satisfy our long-term sales commitments from future supplies available to the Company, our ability to pay dividends in the future and to service our 
outstanding  debt,  dates  or  periods  in  which  production  is  scheduled  or  expected  to  come  on-stream,  as  well  as  our  plans  with  respect  to  capital

these forward-looking statements even if experience or future changes make it clear that the projected results or condition expressed or implied therein 
will not be realized.

From April 1, 1991 until the end of 2001, the Convertibility Law (Law No. 23,928) established a fixed exchange rate which required the Central 
Bank to sell U.S. dollars at one peso per U.S. dollar. On January 6, 2002, the Argentine Congress enacted the Public Emergency and Foreign Exchange 
System Reform Law (Law No. 25,561, the “Public Emergency Law”), formally putting an end to the Convertibility Law regime and abandoning the 
U.S.  dollar-peso  parity.  The  Public  Emergency  Law,  which  had  been  periodically  extended  and  expired  on  December 31,  2017,  by  virtue  of  Law 
No. 27,200,  had  granted  the  National  Executive  Office  the  power  to  set  the  exchange  rate  between  the  peso  and  foreign  currencies  and  to  issue 
regulations  related  to  the  foreign  exchange  market.  Following  a  brief  period  during  which  the  Argentine  government  established  a  temporary  dual 
exchange rate system pursuant to the Public Emergency Law, the peso has been allowed to float freely against other currencies since February 2002, 
although the government has the power to intervene by buying and selling foreign currency for its own account, a practice in which it engages on a 
regular  basis.  The  annual  rate  of  devaluation  of  the  peso  was  approximately  101.4%  from  December 31,  2017  to  December 31,  2018,  based  on  the 
period-end  exchange  rates  for  U.S.  dollars  as  of  December 31,  2018  and  2017.  See  “—Risk  Factors—Risks  Relating  to  Argentina—Our  business  is 
largely dependent upon economic conditions in Argentina.” 

By means of Decree No. 27/2018 dated January 11, 2018, the Free Exchange Market (Mercado Libre de Cambios - “MELI”) was created, as a 
replacement of the Free Single Exchange Market (Mercado Unico Libre de Cambios - “MULC”), for purposes of providing additional flexibility to the 
market,  to  enable  competition  and  allow  for  the  entry  of  new  operators  into  the  foreign  exchange  market,  thus  reducing  systemic  costs.  Exchange 
operations  will  be  conducted  through  the  MELI  by  financial  entities  and  other  participants  authorized  by  the  Central  Bank  to  conduct  regular 
transactions  or  purchase  and  sale  of  foreign  currency,  gold  coins  or  deliverable  gold  bars  and  travelers’  checks,  and  transfers  and  similar  analogous 
foreign exchange operations. 

Pursuant  to  Communication  “A”  6,443  of  the  Central  Bank,  which  became  effective  on  March 1,  2018,  companies  from  any  sector  of  the 
economy which operate on a regular basis in the MELI may act as an exchange agency, as long as they comply with the sole requirement of registering 
their electronic signature in the “Exchange operators’ registry”. 

Currently, the Central Bank may intervene the foreign exchange market by selling dollars into the market when the exchange rate is above 44 
pesos  per  dollar  and  by  buying  dollars  from  the  market  when  the  exchange  rate  falls  below  34  pesos  per  dollar  which  range  was  subject  to  a  daily 
adjustment of 3% per month through the end of 2018, and is currently subject to a daily adjustment of 2% per month (1.75% per month for the second 
quarter of 2019), while the area within such range is considered to be a “non-intervention” zone. 

The following table sets forth the annual high, low, average and period-end exchange rates for U.S. dollars for the periods indicated, expressed in 
nominal pesos per U.S. dollar, based on rates quoted by the Central Bank. The Federal Reserve Bank of New York does not report a noon buying rate 
for the Argentine peso.

Exchange Regulations 

Prior  to  December  1989,  the  Argentine  foreign  exchange  market  was  subject  to  exchange  controls.  From  December  1989  until  April  1991, 
Argentina had a freely floating exchange rate for all foreign currency transactions, and the transfer of dividend payments in foreign currency abroad and 
the  repatriation  of  capital  were  permitted  without  prior  approval  of  the  Central  Bank.  From  April 1,  1991,  when  the  Convertibility  Law  became 
effective,  until  December 21,  2001,  when  the  Central  Bank  closed  the  foreign  exchange  market,  the  Argentine  peso  was  freely  convertible  into  U.S. 
dollars. 

On  December 3,  2001,  the  Argentine  government  imposed  a  number  of  monetary  and  currency  exchange  control  measures  through  Decree 
No. 1,570/01,  which  included  restrictions  on  the  free  disposition  of  funds  deposited  with  banks  and  tight  restrictions  on  transferring  funds  abroad 
(including the transfer of funds to pay dividends) without the Central Bank’s prior authorization subject to specific exceptions for transfers related to 
foreign trade. 

In June 2003, the Argentine government set restrictions on capital flows that came into Argentina, which mainly consisted of a prohibition against 

the transfer abroad of any funds until 180 days after their entry into the country. 

On  June 9,  2005,  by  means  of  Decree  No. 616/2005,  the  National  Executive  Office  established  that  (a) all  inflows  of  funds  into  the  domestic 
foreign  exchange  market  arising  from  foreign  debts  incurred  by  individuals  or  entities  of  the  private  sector,  excluding  foreign  trade  financing  and 
primary issuances of debt securities admitted to public offering and authorized to be listed and/or traded on self-regulatory markets; and (b) all inflows 
of funds of non-residents channeled through the local foreign exchange market to be applied to: holdings of local currency, acquisition of all types of 
financial assets or liabilities in the financial or non-financial private sector, to the exclusion of direct foreign investment and primary issuances of debt 
securities and shares admitted to public offering and authorized to be listed and/or traded in self-regulatory markets, and investments in Government 
securities acquired in secondary markets must meet the following requirements: (i) the funds entering the country may only be transferred out of the 
local foreign exchange market at the expiration of a term of 365 calendar days counted as beginning on the date the funds were received in Argentina; 
(ii) the proceeds of the foreign exchange settlement of the funds received in Argentina must be credited to an account in the local banking system; (iii) a 
registered, non-transferable and non-interest bearing deposit equivalent to 30% of the amount involved in the relevant transaction is to be maintained for 
a term of 365 calendar days in the conditions prescribed by the regulations (the “Mandatory Deposit”); and (iv) the Mandatory Deposit is to be made in 
U.S. dollars and held in a financial institution in Argentina. The Mandatory Deposit shall not accrue interest nor any other type of benefits and it shall 
not be used to secure credit facilities of any type. There are various exceptions to the requirements of Decree No. 616/2005, including but not limited to, 
those detailed below. 

However,  Resolution  No. 3/2015  issued  by  the  Ministry  of  Budget  and  Public  Finances  reduced  the  Mandatory  Deposit  percentage  created  by 
Decree No. 616/2005 from 30% to 0% and reduced the period in which the incoming funds must remain in Argentina from 365 calendar days to 120 
calendar days. Moreover, in January 2017, the Ministry of Treasury reduced the holding period of the Mandatory Deposit from 120 calendar days to 0 
calendar days. As a result of these two changes to the regulations, the Mandatory Deposit is currently not required. 

On  August 8,  2016,  the  Central  Bank  of  the  Argentine  Republic  (“BCRA”  or  “Central  Bank”)  established  a  new  exchange  rate  regime  through 
Communication “A” 6,037, substantially modifying existing exchange regulations and facilitating access to the MULC. On May 19, 2017, the Central 
Bank  issued  Communication  “A”  6,244  which,  effective  as  of  July 1,  2017,  significantly  modified  and  relaxed  all  the  regulations  that  regulated  the 
operation of the MULC. By virtue of this last Communication, all the rules that regulated the exchange operations were replaced by this new regulation, 
including  -  among  others-  the  exchange  rate  transaction,  the  general  position  of  changes,  the  provisions  adopted  by  Decree  No. 616/2005,  and 
maintaining the validity of the regulations related to information regimes, surveys or follow-ups related to such topics. 

10 

In addition, through Communication “A” 6,401 of December 26, 2017, the Central Bank replaced the information regimes and surveys established by 
Communications “A” 3,602 and “A” 4,237 with a unified regime, applicable from the corresponding information as of December 31, 2017. 

The  information  required  will  be  used  exclusively  for  statistical  purposes,  framed  in  the  provisions  of  the  Law  on  Statistics  and  Census  No. 17,622. 
According to the new regime, individuals and legal entities, assets and other universal residents are subject (for example: trusts, joint ventures, business 
collaboration  groups,  cooperation  consortiums  or  other  multilateral  associative  contracts),  which  are  not  included  in  the  category  of  General 
Government according to the definition of the Sixth Edition of the Balance of Payments Manual of the International Monetary Fund. 

Three sample levels were contemplated, whose participants will be determined each calendar year based on: 1) the sum of the flows of external assets 
and liabilities during the previous calendar year; and 2) the balance of holdings of external assets and liabilities at the end of the previous calendar year: 
a) Main sample: any individual or legal entity for which the sum of the flows of external assets and liabilities during the previous calendar year, or the 
balance of external assets and liabilities at the end of that calendar year reaches or exceeds the equivalent of U.S.$ 50 million; b) Secondary sample: any 
individual or legal entity for which the sum of the flows of external assets and liabilities during the previous calendar year, or the balance of external 
assets and liabilities at the end of that calendar year, is between the equivalent of U.S.$ 10 million and U.S.$ 50 million; and c) Complementary sample: 
any individual or legal entity for which the sum of the flows of external assets and liabilities during the previous calendar year, or the balance of external 
assets and liabilities at the end of that calendar year is between the equivalent of U.S.$ 1 million and U.S.$ 10 million. For the rest of the individuals or 
legal entities, the declaration will be optional. In the three samples, an annual declaration must be presented and, in the first case, an advance for each of 
the quarters. External assets and liabilities must be reported according to the following classification: (i) shares and equity interests; (ii) non-negotiable 
debt instruments; (iii) negotiable debt instruments; (iv) financial derivatives; and (v) land, structures and real estate. 

Additionally, Decree No. 893 dated November 1, 2017, in order to improve the competitiveness of Argentine exports, make financing conditions more 
flexible and improve financial predictability, repealed the mandatory entry and settlement of export currencies, as well as the obligation to negotiate the 
currencies so that the exporter could have access to the collection of export refunds. In accordance with the aforementioned decree, Communication “A” 
6,363 of the Central Bank dated November 10, 2017 repealed the sections and other provisions related to the entry and settlement of foreign currency 
from exports. 

Pursuant  to  Communication  “A”  6,436,  which  became  effective  on  January 20,  2018,  the  Central  Bank  derogated  all  foreign  exchange  regulations 
(except for those which were explicitly exempt therefrom), and substituted them with the following: 

•

•

•

•

•

•

•

Any individual or entity may freely conduct operations through MELI. 

All transactions involving foreign exchange must be carried out through an authorized financial entity. 

Timing restrictions to operate in MELI were eliminated. 

Persons subjects to these regulations must comply with the information requirements of the “Foreign Assets and Liabilities Survey”, even in 
those  cases  where  they  have  not  deposited  any  amounts  through  MELI  or  if  they  do  not  anticipate  accessing  such  market  for  any 
transactions subject to reporting. 

The  obligation  to  settle  foreign  exchange  transactions  was  eliminated;  however,  the  intervening  financial  entity  must  continue  to  keep 
records thereof. 

The intervening financial entities must satisfy the applicable regulations relating to anti-money laundering, financing of terrorist activities 
and other illegal activities. 

Foreign exchange transactions shall be conducted at the exchange rate determined by the applicable parties. 

As  a  result,  as  of  the  date  of  this  annual  report,  the  Argentine  government  has  eliminated  the  restrictions  on  access  to  the  MELI  and  there  are  no 
limitations for the repatriation of investments by non-residents, without prejudice to the fact that new exchange control policies could be established in 
the future.

may be exposed to fluctuations in foreign exchange rates.” 

The risks and uncertainties described below are those known by us as of the date of this report. However, such risks and uncertainties may not be the 
only ones that we could face. Additional risks and uncertainties that are unknown to us or that we currently think are immaterial also may impair our 
business operations. 

Risk Factors 

Risks Relating to Argentina 

The Argentine Republic owns 51% of the shares of the Company. 

The Argentine Republic owns 51% of the shares of the Company (see “Item 4. Information on the Company—Legal and Regulatory Framework 
and Relationship with the Argentine Government—The Expropriation Law”), and consequently, the federal government is able to determine all matters 
requiring approval by a majority of shareholders, including the election of a majority of directors. We cannot assure you that the decisions taken by our 
controlling shareholder or its interests, would not differ from your interests as a shareholder, including pricing policy of all our main products, and thus 
affect our operational decisions (see additionally “The result of the next presidential and provincial elections that will take place in 2019 could generate 
uncertainty in the Argentine economy and, consequently, in our businesses and the results of our operations;” “Our domestic operations are subject to 
extensive  regulation”,  and  “Limitations  on  local  pricing  in  Argentina  may  adversely  affect  our  results  of  operations.”)  In  addition,  according  to  the 
Argentine Constitution, presidential elections take place every four years. Argentina’s national election for president and vice-president will take place 
in October 2019, and other relevant local and federal elections will also take place in 2019. Accordingly, changes in government or its policies may 
occur. We cannot assure you if and when any such changes may occur, nor the impact they may have on our business. 

Our business is largely dependent upon economic conditions in Argentina. 

Most  of  our  operations,  properties  and  customers  are  located  in  Argentina,  and,  as  a  result,  our  business  is  to  a  large  extent  dependent  upon 
economic  conditions  prevailing  in  Argentina.  The  changes  in  economic,  political  and  regulatory  conditions  in  Argentina  and  measures  taken  by  the 
Argentine  government  have  had  and  are  expected  to  continue  to  have  a  significant  impact  on  us.  You  should  make  your  own  assessment  about 
Argentina and prevailing conditions in the country before taking an investment decision in us. 

The Argentine economy has experienced significant volatility in past decades, including numerous periods of low or negative growth and high and 
variable levels of inflation and currency devaluation. No assurances can be given that the rate of growth experienced over past years will be achieved in 
future years or that the national economy will not suffer recession. If economic conditions in Argentina were to slow down, or contract, if inflation were 
to  accelerate  further,  or  if  the  Argentine  government’s  measures  to  attract  or  retain  foreign  investment  and  international  financing  in  the  future  to 
incentivize domestic economy activity are unsuccessful, such developments could adversely affect Argentina’s economic growth and in turn affect our 
financial health and results of operations. 

Argentina has confronted and continues to confront inflationary pressures. According to inflation data published by the National Statistics Institute 
(Instituto Nacional de Estadística y Censos) (“INDEC”), in 2018 the consumer price index (“CPI”) and the wholesale price index increased by 47.6% 
and 73.5%, respectively and the three-year cumulative inflation rate has exceeded 100% causing Argentina to be now considered as a hyperinflationary 
economy. See “Item 5. Operating and Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions”. 

Additionally, during 2018 certain macroeconomic variables also suffered and continue to face considerable pressure during 2019, which in turn 
affected  the  development  of  the  domestic  economy.  Among  other  variables,  Argentina  had  increasing  interest  rates  (where  the  BADLAR  averaged 
34.3%  during  2018),  the  Argentine  peso  suffered  a  101%  devaluation  during  the  December  2017-December  2018  period,  preliminary  GDP  (gross 
domestic  product)  growth  rate  during  2018  was  negative  2.5%,  and  Argentina’s  country  risk  climbed  to  817.27  points  on  December 31,  2018  from 
350.97 on December 29, 2017. 

Argentine economic conditions are dependent on a variety of factors, including, but not limited to, the following: 

•

•

•

domestic production, international demand and prices for Argentina’s principal commodity exports; 

stability and competitiveness of the Argentine peso against foreign currencies; 

competitiveness and efficiency of domestic industries and services; 

12 

•

•

•

•

•

•

•

•

•

levels of consumer consumption; 

foreign and domestic investment and financing; 

adverse external economic shocks; 

changes in economic or fiscal policies that may be adopted by the National Government; 

labor disputes and work stoppages, which may affect various sectors of the Argentine economy; 

the level of expenditure by the National Government and the difficulty of reducing the fiscal deficit; 

the level of unemployment, which affects consumption; 

political instability; and 

interest and inflation rates. 

The political parties opposed to the current administration maintained the majority of seats in both houses of the National Congress in the last 
elections,  so  the  new  administration  should  generate  political  consensus  with  the  opposition  to  carry  out  their  economic  proposals.  This  situation 
generates more uncertainty regarding the ability of the National Government to get approval for new measures to be implemented. We cannot predict 
exactly if this situation could generate an adverse change in our financial condition and result of our operations. 

The Argentine  economy is also  sensitive  to local  political  developments. Despite  significant measures  taken by  the Argentine  government  that 
was elected on December 10, 2015 such as reforms in the INDEC, the elimination of exchange restrictions, the elimination or reduction of export taxes 
on certain products (although these restrictions were reinstated in September 2018), the adjustment of gas and electricity prices, tax reform and IMF 
financing, among others. Argentina’s economy continues to face challenges. Inflation remains a challenge for Argentina given its persistent nature in 
recent years and also considering its high levels during 2018. The Argentine Government has announced its intention to reduce the primary fiscal deficit 
as  a  percentage  of  GDP  over  time  and  reduce  the  Government’s  reliance  on  Central  Bank  financing.  If  the  measures  adopted  by  the  Macri 
administration  are  not  able  to  resolve  the  structural  inflationary  disruptions  of  Argentina,  the  current  inflationary  levels  could  subsist  and  have  a 
negative impact on the economic and financial conditions of Argentina, and as such affect our operations and financial situation. 

On May 8, 2018, President Macri announced that the Argentine government would begin negotiations with the IMF with the goal of acquiring a 
stand-by line of credit that would grant Argentina access to IMF financing. On June 8, 2018, the key points of the agreement were made public, which 
consist  of  a  stand-by  loan  for  U.S.$  50 billion,  subject  to  strict  adjustments,  mainly  due  to  fiscal  and  political  concerns,  to  which  the  national 
government  will  be  subject  for  the  upcoming  years.  On  June 22,  2018  the  IMF  made  an  initial  disbursement  of  U.S.$  15.0 billion.  In  addition,  on 
September 26, 2018, Argentina published a new agreement with the IMF. This new agreement supported the three-year stand-by agreement, approved 
on June 20, 2018 and includes an increase in available IMF funds of U.S.$ 19.0 billion through the end of 2019. It also raises the maximum loan amount 
available, to U.S.$ 57.1 billion through 2021. The funds available under the program will no longer be treated as preventive reserves, as the Argentine 
government has indicated that they intend to use IMF financing as budget support. The IMF-supported economic plan aims to strengthen the Argentine 
economy by focusing on four key pillars: (a) restore market confidence; (b) protect society’s most vulnerable sectors; (c) strengthen the credibility of the 
Central Bank’s inflation targeting framework; and (d) progressively lessen the strains on the balance of payments. There are no guarantees on the impact 
that the IMF loan will have on the Argentine economy or on the assets, economic and financial situation of Argentine companies. 

Some of the commitments assumed by the National Government, as counterpart of the IMF loan consist of: reduction of the primary fiscal deficit, 
reaching a surplus in 2021, staggered reduction of inflation until 2021, greater power of the BCRA to establish inflation targets with an anticipation of 
three years and a reduction of the stock of titles of the BCRA proportionate to a level of capital that guarantees its financial autonomy, among others. 
The  agreement  includes  a  “social  clause”  according  to  which,  in  case  the  social  situation  worsens,  the  National  Government  can  deviate  from  the 
objectives to reduce the fiscal deficit and increase social spending for the protection of the most vulnerable sectors. 

On October 26, 2018, IMF approved the extension of the stand-by agreement in an amount of approximately U.S.$ 5.6 billion. The IMF approved 
the first review of Argentina’s performance under the new stand-by agreement and authorized a new transfer of approximately U.S.$ 5.7 billion. In turn, 
a new disbursement schedule was established and the amounts to be disbursed for 2018 and 2019 were expanded. Under this new schedule, the expected 
disbursements  through  the  end  of  2018  were  raised  from  U.S.$  6 billion  to  U.S.$  13.4 billion.  On  December 19,  2018,  the  IMF  approved  a  new 
disbursement of U.S.$ 7.6 billion, which together with the previous two disbursements reached a total amount of U.S.$. 

13 

28.3 billion  for  the  year  2018.  In  April  2019,  Executive  Board  of  the  IMF  will  plan  the  following  disbursement.  We  cannot  predict  exactly  what 
measures will be adopted to comply with the agreements concluded with the IMF or their consequences on the Argentine economy, in general and if this 
could generate an adverse change in our financial condition and result of our operations. 

On September 2018, the Central Bank established a new monetary policy with the aim of reducing the inflation rate. The Central Bank committed 
not  to  increase  the  monetary  base  until  June  2019  and  defined  the  ranges  for  an  intervention  zone  and  a  non-intervention  zone  applicable  to  the 
exchange rate through the end of 2018. On October 2018, the lower limit of the non-intervention zone was established at an exchange rate of 34 pesos 
per dollar and the higher limit was set at 44 pesos per dollar, with a daily adjustment of 3% per month through the end of 2018. If the exchange rate rises 
above the maximum or falls below the minimum values of the area of intervention, the BCRA will purchase or sell foreign currency in an amount of up 
to U.S.$ 50 to U.S.$ 150 million per day, respectively. Within the non-intervention zone, the exchange rate fluctuates freely. During the last quarter of 
2018, the exchange rate has remained within the non-intervention zone, although approaching the lower limit. 

On  December 5,  2018,  BCRA  established  that  the  limits  of  the  non-intervention  zone  will  be  updated  daily  at  a  monthly  rate  of  2%  between 
January 1 and March 31, 2019. On March 14, 2019, BCRA announced that the new limits of the non-intervention zone for the second quarter of 2019 
will be updated daily at a monthly rate of 1.75%. Likewise, this new monetary policy scheme is consistent with the goals of the Ministry of Finance of 
achieving  a  primary  fiscal  balance  in  2019,  and  a  surplus  in  2020.  For  its  part,  BCRA  will  not  carry  out  further  transfers  to  the  Treasury,  thus 
eliminating this source of monetary issuance and reinforcing the BCRA’s commitment to a decreasing inflation over time. During January and February 
2019,  inflation  remained  at  high  levels,  where  the  CPI  increased  by  2.9%  and  3.8%,  respectively,  on  a  month-to-month  basis.  In  addition,  as  of 
March 28, 2019, the peso was valued at Ps. 43.59 per U.S.$1.00, an increase of approximately 15.3% compared to December 31, 2018 

If, despite the measures  adopted by the Macri administration, these measures fail to address Argentina’s structural inflationary imbalances, the 
current  levels  of  inflation  may  continue  or  increase  and  have  an  adverse  effect  on  Argentina’s  economy  and,  indirectly,  on  our  business,  financial 
condition and results of operations. Inflation can also lead to an increase in Argentina’s debt and have an adverse effect on Argentina’s ability to service 
its debt, mainly in the medium and long term when most inflation-indexed debt matures. In addition, weaker fiscal results could have a material adverse 
effect  on  the  Government’s  ability  to  access  long  term  financing,  which,  in  turn,  could  adversely  Argentina’s  economy  and  financial  condition. 
Furthermore,  considering  the  Government’s  macroeconomic  program,  the  Argentine  Republic  may  not  be  able  or  willing  to  access  international  or 
domestic capital markets, and Argentina’s ability to service its outstanding public debt could be adversely affected, and consequently adversely affect 
Argentina’s economic and our financial health and results of operations. See “Item 5. Operating and Financial Review and Prospects—Factors Affecting 
Our Operations—Macroeconomic conditions.” 

Argentina’s economy is also vulnerable to adverse developments affecting its principal trading partners. A deterioration of economic conditions in 
Brazil, Argentina’s main trading partner, and a deterioration of the economies of Argentina’s other major trading partners, such as China or the United 
States, could have a material adverse impact on Argentina’s balance of trade and adversely affect Argentina’s economic growth and, consequently, may 
adversely affect our financial health and results of operations. Furthermore, a significant devaluation of the currencies of our trading partners or trade 
competitors may adversely affect the competitiveness of Argentina and consequently adversely affect Argentina’s economic and our financial health and 
results of operations. 

On  the  other  hand,  a  substantial  increase  in  the  value  of  the  Peso  against  the  U.S.  dollar  would  adversely  affect  Argentina’s  economic 
competitiveness. A significant real appreciation of the Peso would adversely affect exports and increase the trade deficit, which could have a negative 
effect  on  GDP  growth  and  employment,  as  well  as  reduce  the  Argentine  public  sector’s  revenues  by  reducing  tax  collection  in  real  terms,  given  its 
current heavy reliance on taxes on exports. 

Additionally,  as  a  consequence  of  the  emergency  measures  which  the  Argentine  government  adopted  during  or  after  the  2001-2002  Argentine 
economic crisis, foreign shareholders of companies with operations in Argentina began arbitration proceedings against the Argentine government before 
the International Centre for Settlement of Investment Disputes (“ICSID”) pursuant to the arbitration regulations of the United Nations Commission on 
International  Trade  Law  (“UNCITRAL”).  Outstanding  claims  against  the  Argentine  government  before  ICSID  under  UNCITRAL  regulations  may 
entail new awards against the Argentine government, which in turn could have a substantially adverse effect on the Argentine government’s ability to 
implement reforms and to foster economic growth. We cannot assure you that in the future the Argentine government will not breach its obligations. If 
the Argentine government were to default on its debt payment obligations, this would probably result in an impairment of economic activity, an increase 
in  interest  rates,  additional  pressure  on  the  foreign  exchange  market  and  an  increase  in  inflation  rates,  which  in  turn  could  adversely  affect  our 
operations and financial position. Likewise, if Argentina’s access to international private financing or financing from multilateral organizations was 

14 

restricted,  or  the  inflows  of  foreign  direct  investments  was  limited,  it  is  possible  that  Argentina  will  be  unable  to  comply  with  its  obligations  and 
financing from multilateral financial entities may be limited or become unavailable. Additionally, a limitation on Argentina’s ability to obtain financing 
in international markets may have, in the future, an adverse effect on our ability to access international credit markets at standard market rates in order to 
finance our operations. 

The result of the next presidential and provincial elections that will take place in 2019 could generate uncertainty in the Argentine economy and, 
consequently, in our businesses and the results of our operations. 

Argentina’s national election for president and vice-president will take place in October 2019, and other relevant local and federal elections will 
also  take  place  in  2019.  The  impact  that  the  electoral  process  and  its  results  could  have  on  the  policies  and  the  economy  of  Argentina  is  uncertain. 
Additionally, it is not possible to predict the measures that may be adopted by the Macri administration or by any potential new administration at the 
national or provincial level, which could have a substantially adverse effect on the economy or the ability of Argentina to comply with its obligations 
that could affect our financial condition and results of operations. We cannot guarantee that current programs and policies that apply to the oil and gas 
sector  will  continue  in  place  in  the  future.  See  “Risks  relating  to  Our  Business—Limitations  on  local  pricing  in  Argentina  may  adversely  affect  our 
results of operations” and “Risks relating to Our Business—We are exposed to the effects of fluctuations in the prices of oil, gas and refined products.” 

Certain risks are inherent in any investment in a company operating in an emerging market such as Argentina. 

According  to  an  MSCI  (Morgan  Stanley  Capital  International)  release,  Argentina  is considered  a  “border  market”  and  from  May  2019  will  be 
considered  an  “emerging  market”.  The  investing  in  emerging  markets  generally  carries  risks.  These  risks  include  political,  social  and  economic 
instability that may affect Argentina’s economic results which can stem from many factors, including the following: 

•

•

•

•

•

•

•

•

high interest rates; 

abrupt changes in currency values; 

high levels of inflation; 

exchange and capital controls; 

wage and price controls; 

regulations to import equipment and other necessities relevant for operations; 

changes in governmental economic or tax policies; and 

political and social tensions. 

In particular, we continue to actively manage our schedule of work, contracting, procurement and supply-chain activities to effectively manage 
costs. However, price levels for capital and exploratory costs and operating expenses associated with the production of crude oil and natural gas can be 
subject to external factors beyond our control including, among other things, the general level of inflation, commodity prices and prices charged by the 
industry’s  material  and  service  providers,  which  can  be  affected  by  the  volatility  of  the  industry’s  own  supply  and  demand  for  such  materials  and 
services. In the past, we and the oil and gas industry generally experienced an increase in certain costs that exceeded the general trend of inflation. 

Any of these factors, as well as volatility in the capital and foreign exchange markets, may adversely affect our financial condition and results of 

operations or the liquidity, trading markets and value of our securities. 

15 

Failure to adequately address actual and perceived risks of institutional deterioration and corruption may adversely affect Argentina’s economy and 
financial condition. 

A lack of a solid and transparent institutional framework for contracts with the Argentine government and its agencies and corruption allegations 
have affected and continue to affect Argentina. Argentina ranked 85 of 180 in the Transparency International’s 2018 Corruption Perceptions Index and 
117 of 190 in the World Bank’s Doing Business 2018 report. 

As of the date of this annual report, there are various ongoing investigations into allegations of money laundering and corruption being conducted 
by the Office of the Argentine Federal Prosecutor, including the largest such investigation, known as Los Cuadernos de las Coimas (the “Notebooks 
Investigation”)  which  have  negatively  impacted  the  Argentine  economy  and  political  environment.  Depending  on  how  long  it  takes  to  close  said 
investigations and their results, companies involved in the investigations may be subject to, among other consequences, a decrease in their credit ratings, 
claims filed by their investors, and may further experience restrictions in their access to financing through the capital markets, together with a decrease 
in their income. Additionally, as the criminal cases against the companies involved in the investigations move forward, said companies may be restricted 
from rendering services or may face new restrictions, due to their customers’ internal standards. These adverse effects could restrict these companies’ 
ability to conduct their operating activities and to meet their financial obligations. As a consequence of the above, the number of suppliers available for 
our operations may be reduced and, as such, have an adverse effect on our commercial activities and results of operations. 

Recognizing that the failure to address these issues could increase the risk of political instability, distort decision-making processes and adversely 
affect Argentina’s international reputation and ability to attract foreign investment, the Argentine Government has announced several measures aimed at 
strengthening Argentina’s institutions and reducing corruption. These measures include the reduction of criminal sentences in exchange for cooperation 
with  the  government  in  corruption  investigations,  increased  access  to  public  information,  the  seizing  of  assets  from  corrupt  officials,  increasing  the 
powers of the Anticorruption Office (Oficina Anticorrupción) submitting a project for a new public ethic law, among others. The government’s ability to 
implement  these  initiatives  is  uncertain  as  it  would  be  subject  to  independent  review  by  the  judicial  branch,  as  well  as  legislative  support  from 
opposition parties. 

We cannot give any assurance that the implementation of these measures by the Argentine government will be successful in stopping institutional 

deterioration and corruption. 

The Argentine economy has been adversely affected by economic developments in other markets. 

Financial  and  securities  markets  in  Argentina,  and  also  the  Argentine  economy,  are  influenced  by  economic  and  market  conditions  in  other 
markets  worldwide,  including  those  relating  to  a  potential  trade  war  between  China  and  the United States.  Although  economic  conditions vary  from 
country to country, investors’ reactions to events occurring in one country sometimes demonstrate a “contagion” effect in which an entire region or class 
of investment is disfavored by international investors. 

Consequently, there can be no assurance that the Argentine financial system and securities markets will not continue to be adversely affected by 
events  in  developed  countries’  economies  or  events  in  other  emerging  markets,  which  could  in  turn,  adversely  affect  the  Argentine  economy  and, 
indirectly, our business, financial condition and results of operations, and the market value of our ADSs. 

The implementation of new export duties, other taxes and import regulations could adversely affect our results. 

In the past, the Argentine government established export taxes on certain hydrocarbon products by Law No. 25,561 of Public Emergency, for a 
period of five years. That period was extended for five more years by Law No. 26,732. The second extension expired on January 7, 2017 and was not 
extended. As a result, export duties on hydrocarbon products ceased to apply. 

However, on September 4, 2018, Decree No. 793/2018 was published which establishes an export duty of 12% on the export for consumption of 
all merchandise included in tariff positions of the Common Mercosur Nomenclature through December 31, 2020. This export duty may not exceed 4 
pesos per U.S. dollar of the taxable value or the official FOB price, as applicable. For merchandise which does not constitute primary sector products, 
the  duty  may  not  exceed  3  pesos  per  U.S.  dollar  of  the  taxable  value  or  the  official  FOB  price,  as  applicable.  See  “Item  4.  Information  on  the 
Company—Legal and Regulatory Framework and Relationship with the Argentine Government—Market Regulation.” 

We  cannot  assure  you  that  taxes  and  import/export  regulations  of  this  nature  will  not  be  modified  in  the  future  or  that  other  new  taxes  or 

import/export regulations will not be imposed. 

We may be exposed to fluctuations in foreign exchange rates. 

Our results of operations are exposed to currency fluctuations, and any devaluation of the peso against the U.S. dollar and other hard currencies 
may  adversely  affect  our  business  and  results  of  operations  (See  “Risks  relating  to  Our  Business  —Limitations  on  local  pricing  in  Argentina  may 
adversely affect our results of operations.”). The value of the peso has fluctuated significantly in the past, such as in January 2014 when the Argentine 
peso  declined  approximately  23%  against  the  U.S.  dollar  and  in  December  2015  when  the  value  of  Argentine  Peso  decreased  approximately  40% 
against the U.S. dollar. During 2018, the value of the Argentine Peso reached its minimum value on September 2018 when the value of the Argentine 
Peso fell to 40.90 per U.S.$1.00, a decrease of approximately 118% 

16 

against the U.S. dollar compared to December 31, 2017. As of December 31, 2018, the value of the Argentine Peso amounted to Ps. 37.81 per U.S.$1.00 
which  represented  a  year-over-year  depreciation  of  approximately  101%.  As  of  March 28,  2019,  the  peso  was  valued  at  Ps.  43.59  per  U.S.$1.00,  an 
increase of approximately 15% compared to December 31, 2018. See “Item 5. Operating and Financial Review and Prospects—Factors Affecting Our 
Operations—Macroeconomic  conditions”  for  additional  information.  The  main  effects  of  the  devaluation  of  the  Argentine  peso  on  our  net  profit  are 
related to (i) deferred income tax related mainly to fixed assets, which we expect would have a negative effect; (ii) current income tax; (iii) increased 
depreciation and amortization resulting from the remeasurement in pesos of our fixed and intangible assets; (iv) exchange rate differences as a result of 
our exposure to the peso, which we expect would have a positive effect due to the fact that our functional currency is the U.S. dollar and (v) higher 
revenues because domestic prices in Argentina for our main products are principally based on international prices quoted in U.S. dollars (See “Risks 
relating  to  Our  Business—We  are  exposed  to  the  effects  of  fluctuations  in  the  prices  of  oil,  gas  and  refined  products.”  and  “Item  5.  Operating  and 
Financial  Review  and  Prospects—Factors  Affecting  Our  Operations—Macroeconomic  conditions”).  In  addition,  regarding  our  financial  position  the 
majority of our debt is denominated in currencies other than the peso; consequently, a devaluation of the peso against such currencies will increase the 
amount of pesos we need to cope with in the terms of loans. 

We are unable to predict whether, and to what extent, the value of the peso may further depreciate or appreciate against the U.S. dollar and how 

any such fluctuations could affect our business. 

Variations  in  interest  rates  and  exchange  rate  on  our  current  and/or  future  financing  arrangements  may  result  in  significant  increases  in  our 
borrowing costs. 

Under  our  financing  arrangements,  we  are  permitted  to  borrow  funds  to  finance  the  purchase  of  assets,  incur capital  expenditures,  repay  other 
obligations and finance working capital. As of December 31, 2018, approximately 18% of our total debt is sensitive to changes in interest rates, mainly 
those  prevailing  in  the  domestic  market.  See  “Item  11.  Quantitative  and  Qualitative  Disclosures  about  Market  Risk—Interest  rate  exposure.” 
Consequently,  variations  in  interest  rates  could  result  in  significant  changes  in  the  amount  required  to  cover  our  debt  service  obligations  and  in  our 
interest  expense,  thus  affecting  our  results  and  financial  condition.  In  addition,  interest  and  principal  amounts  payable  pursuant  to  debt  obligations 
denominated  in  or  indexed  to  U.S.  dollars  are  subject  to  variations  in  the  Argentine  peso/U.S.  dollar  exchange  rate  that  could  result  in  a  significant 
increase in peso terms in the amount of the interest and principal payments in respect of such debt obligations. 

We could be subject to exchange and capital controls. 

In the past, Argentina imposed exchange controls and transfer restrictions substantially limiting the ability of companies to retain foreign currency 
or  make  payments  abroad.  Beginning  in  2011,  additional  foreign  exchange  controls  have  been  imposed  that  restrict  or  limit  purchases  of  foreign 
currency and transfers of foreign currency abroad. Since 2011, oil and gas companies (including YPF), among other entities, were required to repatriate 
100% of their foreign currency export receivables. 

In  December  2015,  the  new  administration  eliminated  certain  exchange  controls  imposed  by  the  previous  administration,  such  as  (i) the 
requirement that foreign currency be deposited and exchanged in Argentina in respect of finance transactions outside Argentina, and (ii) the requirement 
that 30% of funds in U.S. dollars held in Argentina be frozen pursuant to Decree No. 616/05. Additionally, through BCRA Communication “A” 6244, 
the Central Bank derogated the regulations relating to restrictions on exchange rate transactions, settlement of foreign exchange transactions, and the 
provisions  of  Decree  No. 616/05,  except  for  those  regulations  relating  to  information  regimes,  surveys  or  similar  informational  matters  relating  to 
foreign exchange transactions. Following these changes, the Argentine Peso fell to Ps. 12.99 per U.S.$ 1.00, as of December 31, 2015, a decrease of 
approximately  52%  compared  to  December 31,  2014.  Between  December 16,  2015  and  December 31,  2015,  the  peso  decreased  approximately  40% 
against the U.S. dollar. As of December 31, 2018, the Argentine Peso fell to Ps. 37.81 per U.S.$ 1.00 which represented a year-over-year depreciation of 
approximately 101%. As of March [    ], 2019, the peso fell to Ps. [    ] per U.S.$ 1.00, an increase of approximately [    ]% compared to December 31, 
2018. See “Item 4. Information on the Company—Legal and Regulatory Framework and Relationship with the Argentine Government—Repatriation of 
Foreign Currency.” 

17 

There can be no assurance that future regulatory changes related to exchange and capital controls will not adversely affect our financial condition 
or  results  of  operations,  our  ability  to  meet  our  obligations  denominated  in  foreign  currency  or  our  ability  to  execute  our  financing  and  capital 
expenditure plans. 

Our  access  to  international  capital  markets  and  the  market  price  of  our  shares  are  influenced  by  the  perception  of  risk  in  Argentina  and  other 
emerging economies. 

According  to  an  MSCI  (Morgan  Stanley  Capital  International)  release,  Argentina  is considered  a  “border  market”  and  from  May  2019  will  be 
considered  an  “emerging  market”.  Economic  and  market  conditions  in  Argentina  and  in  other  emerging  market  countries,  especially  those  in  Latin 
America, influence the market for securities issued by Argentine companies. Volatility in securities markets in Latin America and in other emerging 
market countries may  have a negative impact on the trading value of our securities  and on  our ability and the terms  on which we are able to access 
international capital markets. Moreover, regulatory and policy developments in Argentina that occurred in recent years, including the enactment of the 
Expropriation Law, as well as the litigation of the Argentine government with Holdout Bondholders have led to considerable volatility in the market 
price of our shares and ADSs. See “—Our business is largely dependent upon economic conditions in Argentina.” We cannot assure that the perception 
of risk in Argentina and other emerging markets may not have a material adverse effect on our ability to raise capital, including our ability to refinance 
our debt at maturity, which would negatively affect our investments plans and consequently our financial condition and results of operations, and also 
have a negatively impact on the trading values of our debt or equity securities. We can give no assurance as to potential adverse impact of the factors 
discussed above on our financial condition and/or results of operations. See “Item 4. Information on the Company—History and Development of YPF.” 

Risks Relating to our Business 

We are exposed to the effects of fluctuations in the prices of oil, gas and refined products. 

Most  of  our  revenue  in  Argentina  is  derived  from  sales  of  refined  products  (mainly  gasoline  and  diesel)  and,  to  a  lesser  extent,  natural  gas. 
International  prices  for  oil  and  oil  products  are  volatile  and,  since  the  liberalization  of  the  domestic  market  at  the  end  of  2017,  the  prices  of  our  oil 
products,  are  strongly  influenced  by  conditions  and  expectations  of  world  supply  and  demand,  among  other  factors.  Volatility  and  uncertainty  in 
international prices for crude oil, oil products will most likely continue. With respect of our pricing policy of fuels see “Limitations on local pricing in 
Argentina may adversely affect our results of operations.” 

In terms of investments, we budget capital expenditures related to exploration, development, refining and distribution activities by considering, 
among  other  things,  current  and  expected  local  and  international  market  prices  for  our  hydrocarbon  products.  In  general  terms,  we  had  come  from 
domestic  prices  for  crude  oil  higher  than  international  benchmark  prices,  however  during  2017  we  entered  into  a  convergence  process  towards  to 
international  prices  that  finally  occurred  in  October  2017  when  prices  were  liberalized  (see  “Item  5.  Operating  and  Financial  Review  and 
Prospects—Factors Affecting Our Operations—Macroeconomic conditions”). 

Nevertheless, due to various factors (including, but not limited to, the abrupt variation in the exchange rate and the increase in international prices 
of  oil  and  the  consequent  difficulties  to  pass-through  the  corresponding  variation  to  domestic  prices)  the  intended  liberalization  could  not  be  fully 
realized during 2018. Accordingly, we cannot guarantee that the liberalization of oil and fuel prices in the domestic market may finally operate in the 
future due to various factors such as, domestic demand, macroeconomic and political conditions prevailing in Argentina or potential new regulatory or 
legal limitations. The international price of crude oil has fluctuated significantly in the past and, if crude oil prices in the domestic market drop for an 
extended period (or if prices for certain products do not match cost increases), this could negatively affect the economic viability of our drilling projects. 
These reductions could lead to changes to our development plans, which could lead to the loss of proved developed reserves and proved undeveloped 
reserves and could also adversely affect our ability to improve our hydrocarbon recovery rates, find new reserves, develop unconventional resources and 
carry out certain of our other capital expenditure plans. In turn, these changes in conditions could have an adverse effect on our financial condition and 
results of operations. Additionally, they could also have an impact on our operating assumptions and estimates and, as a result, affect the recovery value 
of certain assets. 

18 

Furthermore, we may be required to further write down the carrying value of our properties if estimated oil and gas prices decline or if we have 
substantial  downward  adjustments  to  our  estimated  reserves,  increases  in  our  operating  costs,  increases  in  the  discount  rate,  among  others.  See 
additionally “Item 5. Operating and Financing Review and Prospects—Critical Accounting Policies” for information regarding our sensitivity analysis 
related to impairment. In addition, if a reduction in our capital expenditures materializes, including the capital expenditures of our domestic competitors, 
it would likely have a negative impact on the number of active drilling rigs, workovers and pulling equipment in Argentina, alongside related services, 
thus affecting the number of active workers in the industry. We are unable to predict whether, and to what extent, the potential consequences of such 
measures could affect our business, have an impact on our production and consequently affect our financial condition and results of operations. 

Our domestic operations are subject to extensive regulation. 

The Argentine oil and gas industry is subject to government regulation and control. As a result, our business is to a large extent dependent upon 
regulatory and political conditions prevailing in Argentina and our results of operations may be adversely affected by regulatory and political changes in 
Argentina.  (see  “Limitations  on  local  pricing  in  Argentina  may  adversely  affect  our  results  of  operations”  and  “We  are  exposed  to  the  effects  of 
fluctuations in the prices of oil, gas and refined products”). Although recently the Argentine government has promoted and tried to implement policies 
seeking to have domestic prices converge with those of international markets, we may face risks and challenges relating to government regulation and 
control of the energy sector, including those set forth below and elsewhere in these risk factors: 

•

•

•

•

•

•

•

•

limitations on our ability to increase local prices or to reflect the effects of higher domestic taxes, increases in production costs or 
increases in international prices of crude oil and other hydrocarbon fuels and exchange rate fluctuations on our domestic prices. See 
“—Limitations on local pricing in Argentina may adversely affect our results of operations”; 

new export duties, similar taxes or regulations on imports; 

limitations on hydrocarbon export volumes, driven mainly by the requirement to satisfy domestic demand; 

in connection with the Argentine government’s policy to provide absolute priority to domestic demand, regulatory orders to supply 
natural gas and other hydrocarbon products to the domestic retail market in excess of previously contracted amounts, or at prices 
lower  than  those  related  to  import  parity  or  those  we  may  obtain  if  regulated  margins  were  not  being  imposed  or  suggested.  See 
“Item  4. 
the  Argentine 
Government—Market Regulation—Natural gas”; 

the  Company—Legal  and  Regulatory  Framework  and  Relationship  with 

Information  on 

in connection with the former and current incentive programs established by the Argentine government for the oil and gas industry, 
such  as  the  “Natural  Gas  Additional  Injection  Stimulus  Program”  and  the  “Investment  in  Natural  Gas  Production  from 
Non-Conventional Reservoirs Stimulus Program” (“Gas Plan”) (see “A significant percentage of our cash flow from operations is 
derived from counterparties that are governmental entities”) and cash collection of balances with the Argentine government, which 
are additionally subject to the risk of potential changes in current regulations that could affect our projections or profitability. See 
“Item  4. 
the  Argentine 
Government—Market Regulation—Natural gas”; 

the  Company—Legal  and  Regulatory  Framework  and  Relationship  with 

Information  on 

legislation  and  regulatory  initiatives  relating  to  hydraulic  stimulation  and  other  drilling  activities  for  unconventional  oil  and  gas 
hydrocarbons, which could increase our cost of doing business or cause delays and adversely affect our operations; 

restrictions on imports of products which could affect our ability to meet our delivery commitments or growth plans, as the case may 
be; and 

the implementation or imposition of stricter quality requirements for petroleum products in Argentina. 

In past years, the Argentine government has made certain changes in regulations and policies governing the energy sector to give absolute priority 
to  domestic  supply  at  stable  prices  in  order  to  sustain  economic  recovery.  As  a  result  of  the  above-mentioned  changes,  for  example,  on  days  during 
which a gas shortage occurs, exports of natural gas (which are also affected by other government curtailment orders) and the provision of gas supplies to 
industries,  electricity  generation  plants  and  service  stations  selling  compressed  natural  gas  are  interrupted  for  priority  to  be  given  to  residential 
consumers. The Expropriation Law has declared achieving self-sufficiency in the supply of hydrocarbons as well as in the exploitation, industrialization, 
transportation  and  sale  of  hydrocarbons,  a  national  public  interest  and  a  priority  for  Argentina.  In  addition,  its  stated  goal  is  to  guarantee  socially 
equitable economic development, the creation of jobs, the increase of the competitiveness of various economic sectors and the equitable and sustainable 
growth of the Argentine provinces and regions. See “Item 4. Information on the Company—Legal and Regulatory Framework and Relationship with the 
Argentine  Government—The  Expropriation  Law,”  and  “—Risks  Relating  to  Argentina—The  Argentine  Republic  owns  51%  of  the  shares  of  the 
Company.” 

19 

We  cannot  assure  you  that  changes  in  applicable  laws  and  regulations,  or  adverse  judicial  or  administrative  interpretations  of  such  laws  and 
regulations,  will  not  adversely  affect  our  results  of  operations.  See  “Item  4.  Information  on  the  Company—Legal  and  Regulatory  Framework  and 
Relationship with the Argentine Government.” 

Limitations on local pricing in Argentina may adversely affect our results of operations. 

Due  to  regulatory,  economic  and  government  policy  factors,  our  domestic  gasoline,  diesel,  natural  gas  and  other  fuel  prices  have  sometimes 
differed substantially from prevailing international and regional market prices for such products, and our ability to increase prices in connection with 
international  price  increases  or  domestic  cost  increases,  including  those  resulting  from  the  peso  devaluation,  has  been  limited  from  time  to  time.  In 
general  terms,  we  had  come  from  domestic  prices  for  crude  oil  higher  than  international  benchmark  prices,  however  during  2017  we  entered  into  a 
convergence  process  towards  to  international  prices  that  finally  occurred  in  October  2017  when  prices  were  liberalized,  see  “Item 5.  Operating  and 
Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions.” 

As a result of the liberalization of the domestic market, our pricing policy for fuels contemplates several factors such as international crude oil 
prices  and,  refining  spreads,  processing  and  distribution  costs,  biofuel  prices,  exchange  rate,  local  demand  and  supply,  competition,  inventories, 
withholding tax on exports, local taxation, and domestic margins for our products, among others. Nevertheless, due to various factors (including, but not 
limited  to, the  abrupt variation in the  exchange rate and the increase in  international prices of  oil and the consequent difficulties to pass-through the 
corresponding variation to domestic prices) the intended liberalization could not be fully realized during 2018. Accordingly, we cannot guarantee that 
the  liberalization  of  oil  and  fuel  prices  in  the  domestic  market  may  finally  operate  in  the  future  due  to  various  factors  such  as,  domestic  demand, 
macroeconomic  and  political  conditions  prevailing  in  Argentina,  the  interests  of  our  controlling  shareholder,  or  potential  new  regulatory  or  legal 
limitations (see “Item 5. Operating and Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions”). 

On the other hand, Argentina has faced and continues to face high inflationary pressures, which the Argentine Government continues to approach 
through  different  measures.  The  Government  has  the  objective  of  reducing  inflation,  in  line  with  the  agreement  with  IMF  and  pursuant  to  the  new 
policies put in place by the BCRA. Consequently, and taking into account the impact of the increase in the price of fuels in the aforementioned inflation, 
we cannot guarantee that we will be able to increase our fuel prices to compensate for the general increases in costs or import prices. (See “Our business 
is largely dependent upon economic conditions in Argentina.”) 

Regarding natural gas markets, revenues we obtain as a result of selling natural gas in Argentina (including amounts received through the Gas 
Plan,  see  “Item 4.  Information  on  the  Company—Legal  and  Regulatory  Framework  and  Relationship  with  the  Argentine  Government—Market 
Regulation—Natural gas” and “MINEM Resolution No. 46/2017”) are subject to government regulations and could be negatively affected, principally 
considering the evolution of gas prices for residential consumers which in turn are still subject to subsidies and the evolution of sale price to electric 
generation plants. The prices that we are able to obtain for our hydrocarbon products affect the viability of investments in new exploration, development 
and refining and, as a result, the timing and amount of our projected capital expenditures for such purposes. We budget capital expenditures by taking 
into  account,  among  other  things,  market  prices  for  our  hydrocarbon  products.  For  additional  information  on  domestic  pricing  for  our  products,  see

A significant percentage of our cash flow from operations is derived from counterparties that are governmental entities. 

In the normal course of business and considering that we are the primary oil and gas company in Argentina, our portfolio of clients and suppliers 
includes both private sector and governmental entities. All material transactions and balances with related parties as of December 31, 2018 are set forth 
in  Note  31  to  the  Audited  Consolidated  Financial  Statements,  including,  among  others,  accounts  receivables  with  SGE  (related  to  the  Natural  Gas 
Stimulus  Programs),  Ministry  of  Transport  (related  to  compensation  for  providing  gas  oil  to  public  transport  at  a  differential  price)  and  Aerolineas 
Argentinas (related to the provision of jet fuel). 

20 

As  of  December 31,  2018,  the  accounts  receivable  balance  corresponding  to  the  Natural  Gas  Additional  Injection  Stimulus  Program  reflects 
twelve  months  of  accrued,  unpaid  payments  for  year  2017,  representing  Ps.  27.0 billion.  As  of  the  date  of  this  annual  report,  we  have  not  received 
additional payments related to amounts accrued and unpaid as of December 31, 2018 under such program. However, on February 28, 2019, the SGE 
notified YPF the amount of the compensation owed to it, estimated in compliance with Resolution No. 97/2018, which amounted to U.S.$ 758 million. 
See “Item 4. Information on the Company—Legal and Regulatory Framework and Relationship with the Argentine Government— MINEM Resolution 
No. 97/2018.” 

As  of  December 31,  2018,  the  accounts  receivable  corresponding  to  the  Stimulus  Program  for  Investments  in  Developments  of  Natural  Gas 
Production  from  Unconventional  Reservoirs  reflects  twelve  months  of  accrued,  unpaid  payments,  representing  Ps.  1.2 billion.  As  of  the  date  of  this 
annual report, we have received payments of Ps. 0.3 billion related to amounts accrued and unpaid as of December 31, 2018 under such program. 

Additionally,  because  of  the  variation  in  the  exchange  rate,  natural  gas  producers  and  distributors  began  a  process  of  renegotiation  of  the  specific 
agreements  signed  pursuant  to  the  Terms  and  Conditions  for  the  Provision  of  Natural  Gas  to  Gas  Distributors  through  Networks  (the  “Terms  and 
Conditions”) (see “Item 4. Information on the Company—Exploration and Production—Delivery commitments—Natural gas supply contracts)”, where 
prices were denominated in dollars. The renegotiation process included two main aspects: i) payments of the debts arising from the differences between 
the exchange rate paid by the distributors and the exchange rate which had been originally agreed (for the period between April and September 2018), 
and ii) the applicable price for gas during the period between October and December 2018. On November 16, 2018, through Decree No. 1,053/18 the 
Argentine  Government  assumed  on  an  exceptional  basis,  the  payment  of  the  daily  differences  which  accrued  monthly  between  the  price  of  gas 
purchased by the distributors and the valid tariffs during the period between April 1, 2018, and March 31, 2019, exclusively arising from exchange rate 
variations and corresponding to the natural gas volumes delivered in that same period. The conditions are as follows: 

• 30 monthly consecutive installments starting on October 1, 2019, which will be determined by using the BNA effective interest rate for 30-day 

deposits in Argentine currency (“electronic board”). 

• The installments will be collected by distributors, who will immediately pass it through to producers. 

• Distributors and producers must adhere to the system and expressly waive any action or complaint. 

As of the date of this annual report, the complementary regulations for the application of the foregoing conditions to distributors and producers are 
pending issuance by the ENARGAS. See additionally “Item 4. Information on the Company—Legal and Regulatory Framework and Relationship with 
the Argentine Government— Tariff renegotiation.” 

If certain governmental counterparties were (i) not able to pay or redeem such accrued amounts in cash or cash equivalents, or (ii) only able to 
make such payments or redemptions through delivery of financial instruments which: (a) may delay collection of working capital payments in excess of 
our estimates, (b) are subject to change in their listing value, or (c) are denominated a currency other than the origin of the credit, our financial condition 
and results of operations could be adversely affected. 

We are subject to direct and indirect import and export restrictions, which have affected our results of operations and caused us to declare force 
majeure under certain of our export contracts. 

The Argentine Hydrocarbons Law No. 17,319, allows for hydrocarbon exports as long as they are not required for the domestic market and are 
sold at reasonable prices. In the case of natural gas, Law No. 24,076 and related regulations require that the needs of the domestic market be taken into 
account when authorizing long-term natural gas exports. 

In  the  past,  the  Argentine  authorities  have  adopted  a  number  of  measures  that  have  resulted  in  restrictions  on  exports  of  natural  gas  from 
Argentina. Due to the foregoing, we have been obliged to sell a part of our natural gas production previously destined for the export market in the local 
Argentine market and have not been able to meet our contractual gas export commitments in whole or, in some cases, in part, leading to disputes with 
our export clients and forcing us to declare force majeure under our export sales agreements. We believe that the measures mentioned above constitute 
force majeure events, although no assurance can be given that this position will prevail. 

See  “Item  4.  Information  on  the  Company—Exploration  and  Production—Delivery  commitments—Natural  gas  supply  contracts,”  “Item  4. 
Information  on  the  Company—Exploration  and  Production—The  Argentine  natural  gas  market,”  and  “Item  8.  Financial  Information—Legal 
Proceedings.”

Crude oil exports, as well as the export of most of our hydrocarbon products, currently required prior authorization from the SGE pursuant to the 
regime established under S.E. Resolution No. 241-E/17, as amended and supplemented by other regulation. Oil companies seeking to export crude oil or 
LPG must first demonstrate that the local demand for such product is satisfied or that an offer to sell the product to local purchasers has been made and 
rejected. Oil refineries seeking to export diesel must also first demonstrate that the local demand for diesel is duly satisfied. 

In addition, on March 21, 2017, Decree No. 192/2017 was published in the Official Gazette of the Republic of Argentina (the “Official Gazette”), 
which  created  the  “Oil  and  its  Byproducts  Import  Operations  Registry”  (the  “Registry”)  and  set  forth  that  the  MINEM  (through  the  Secretariat  of 
Hydrocarbon Resources) would be responsible controlling the Registry. The Registry involved import operations of: (i) crude oil and (ii) certain other 
specific  byproducts  listed  in  section 2  of  the  decree.  By  means  of  this  regulation,  any  company  that  wished  to  perform  such  import  operations  was 
obligated to register such operation in the Registry and to obtain authorization from MINEM before the import took place. According to this decree, 
MINEM had to set the methodology applicable to issue import authorizations, which will be based in the following criteria: (a) lack of crude oil with the 
same characteristics offered in the domestic market; (b) lack of additional treatment capacity in domestic refineries with domestic crude oil; and (c) lack 
of  byproducts  listed  in  section 2  of  the  decree  offered  in  the  domestic  market.  This  regime  exempted  any  import  by  CAMMESA  in  order  to  supply 
power plants with the main purpose of technical supply to the “Inter-connection Argentinean System” (Sistema Argentino de Interconexión or “SADI”). 
On  November 24,  2017,  Decree  No. 962/2017  was  published  in  the  Official  Gazette  amending  Decree  No. 192/2017  by  providing  that  the  Registry 
would  be  in  effect  until  December 31,  2017.  Decree  No. 962/2017  provided  that  the  need  for  the  Registry  was  temporary  and  therefore,  since 
December 31,  2017,  the  import  operations  related  to  crude  oil,  gasoline,  and  diesel  oil  included  in  Decree  No. 192/2017  are  no  longer  subject  to 
registration. 

On August 22, 2018, the former Ministry of Energy and Mining issued Resolution No.104/2018, later modified by Resolution No. 9/2018 of the 
SGE, which established a new procedure to obtain authorizations to export natural gas. For more information, see “— Legal and Regulatory Framework 
and Relationship with the Argentine Government—“Natural gas export administration and domestic supply priorities.” 

We are unable to estimate how long these restrictions will be in place, or whether any further measures will be adopted that adversely affect our 

ability to export or import gas, crude oil and diesel or other products and, accordingly, our results of operations. 

Our reserves and production are likely to decline. 

Most of our existing oil and gas producing fields in Argentina are mature and, as a  result, our reserves and production are likely to decline as 
reserves are depleted. Our production decreased in 2018 compared to 2017 by 4.5% and our reserves replacement ratio (increases in reserves in the year, 
net divided by the production of the year) was 178% in 2018, compared to 9% in 2017. 

We face certain challenges in order to replace our proved reserves with other categories of hydrocarbons. However, the continuous comprehensive 
technical  review  of  our  oil  and  gas  fields  allows  us  to  identify  opportunities  to  rejuvenate  mature  fields  and  optimize  new  field  developments  in 
Argentine  basins  with  the  aim  of  achieving  results  similar  to  those  achieved  by  mature  fields  in  other  regions  of  the  world  (which  have  achieved 
substantially higher recovery factors with the application of new technology). Additionally, we have been completing the renewal or extension of most 
of  our  concessions,  allowing  us  to  develop  certain  strategic  projects  related  to  water-flooding,  enhanced  oil  recovery  and  unconventional  resources, 
which  represent  an  important  opportunity  not  only  for  us  but  also  for  Argentina.  We  expect  that  unconventional  development  will  require  higher 
investment in future years, principally in connection with the Vaca Muerta formation. These investments are expected to yield economies of scale, de 
risk undeveloped acreage and to significantly increase recovery rates from this resource play. Other resource plays, unconventional prospects, exist in 
Argentina  and  have  positioned  the  country  amongst  the  most  attractive  in  terms  of  worldwide  unconventional  resource  potential.  Nevertheless,  the 
financial  viability  of  these  investments  and  reserve  recovery  efforts  will  generally  depend  on  the  prevailing  economic  and  regulatory  conditions  in 
Argentina, as well as the market prices of hydrocarbon products, and are also subject to material risks inherent to the oil and gas industry. See “—Our 
business  plan  includes  future  drilling  activities  for  unconventional  oil  and  gas  reserves,  such as  shale  oil  and gas  extraction,  and if  we are  unable  to 
successfully acquire and use the necessary new technologies and other support as well as obtain financing and venture partners, our business may be 
adversely affected.” 

Our oil and natural gas reserves are estimates. 

Our oil and gas proved reserves are estimated using geological and engineering data to determine with reasonable certainty whether the crude oil 
or natural gas in known reservoirs is recoverable under existing economic and operating conditions. The accuracy of proved reserve estimates depends 
on a number of factors, assumptions and variables, some of which are beyond our control. Factors susceptible 

22 

to our control include drilling, testing and production after the date of the estimates, which may require substantial revisions to reserves estimates; the 
quality of available geological, technical and economic data used by us and our interpretation thereof; the production performance of our reservoirs and 
our  recovery  rates,  both  of  which  depend  in  significant  part  on  available  technologies  as  well  as  our  ability  to  implement  such  technologies  and  the 
relevant know-how; the selection of third parties with which we enter into business; and the accuracy of our estimates of initial hydrocarbons in place, 
which may prove to be incorrect or require substantial revisions. Factors mainly beyond our control include changes in prevailing oil and natural gas 
prices,  which  could  have  an  effect  on  the  quantities  of  our  proved  reserves  (since  the  estimates  of  reserves  are  calculated  under  existing  economic 
conditions when such estimates are made); changes in the prevailing tax rules, other government regulations and contractual conditions after the date 
estimates are made (which could make reserves no longer economically viable to exploit); and certain actions of third parties, including the operators of 
fields in which we have an interest. 

Information on net proved reserves as of December 31, 2018, 2017 and 2016 was calculated in accordance with SEC rules and FASB’s ASC 932, 

as amended. Accordingly, crude oil prices used to determine reserves were calculated each month, for crude oils of different quality produced by us. 

As previously discussed, we had come from domestic prices for crude oil higher than international benchmark prices, however during 2017 we 
entered  into  a  convergence  process  towards  to  international  prices  that  finally  occurred  in  October  2017  when  prices  were  liberalized.  See  “Item  5. 
Operating and Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions.” Nevertheless, due to various factors 
(including, but not limited to, the abrupt variation in the exchange rate and the increase in international prices of oil and the consequent difficulties to 
pass-through the corresponding variation to domestic prices) the intended liberalization could not be fully realized during 2018. Accordingly, we cannot 
guarantee that the liberalization of oil and fuel prices in the domestic market may finally operate in the future due to various factors such as, domestic 
demand, macroeconomic and political conditions prevailing in Argentina or potential new regulatory or legal limitations. As a result, for calculations of 
our net proved reserves as of December 31, 2018, the Company considered the realized prices for crude oil in the domestic market taking into account 
the effect of export taxes as in effect as of each of the corresponding years (until 2020, in accordance with Decree No. 793/2018). For the years beyond 
the mentioned periods, the Company considered the unweighted average price of the first-day-of-the-month for each month within the twelve-month 
period  ended  December 31,  2018,  which  refers  to  the  Brent  prices  adjusted  by  each  different  quality  produced  by  the  Company.  In  connection  with 
natural gas prices used for estimation of reserves, the Company considered the realized prices in the domestic market according to the SEC and FASB’s 
ASC 932 rules, but also taking into account the effect of certain market regulations which were put in place mainly during the second half of 2018. 

The international price of crude oil has fluctuated significantly in the past. If these prices decrease significantly in the future or if domestic prices 
are set lower than in internationals markets, our future calculations of estimated proved reserves would be based on lower prices. This could result in our 
having  to  remove  non-economic  reserves  from  our  proved  reserves  in  future  periods.  Assuming  all  other  factors  remain  constant,  if  commodity 
reference prices for crude oil used in our year-end reserve estimates were decreased by 10%, our total proved reserves as of December 31, 2018 would 
decrease  by  approximately  2%.  On  the  other  hand,  assuming  all  other  factors  remain  constant,  if  market  prices  for  natural  gas  used  in  our  year-end 
reserve  estimates  were  decreased  by  10%,  our  total  proved  reserves  as  of  December 31,  2018  would  decrease  by  approximately  1%.  Furthermore, 
assuming all other factors remain constant, if costs used in our year-end reserve estimates were increased by 10% for crude oil and natural gas, our total 
proved  reserves  as  of  December 31,  2018  would  decrease  by  approximately  2%.  However,  if  we  combine  the  3  above  mentioned  effects,  our  total 
proved reserves as of December 31, 2018 would decrease by approximately 7%. In addition, as a result of the prices used to calculate the present value 
of future net revenues from our proved reserves, in accordance with SEC rules, which are similar to the calculation of proved reserves described above, 
the present value of future net revenues from our proved reserves will not necessarily be the same as the current market value of our estimated crude oil 
and natural gas reserves. 

As a result of the foregoing, measures of reserves are not precise and are subject to revision. Any downward revision in our estimated quantities of 
proved reserves could  adversely  impact our  financial  results  by  leading  to  increased depreciation, depletion  and  amortization charges or impairment, 
which  could  reduce  earnings  and  shareholders’  equity.  See  “—We  are  exposed  to  the  effects  of  fluctuations  in  the  prices  of  oil,  gas  and  refined 
products.” 

Oil and gas activities are subject to significant economic, environmental and operational risks and to seasonal fluctuation of demand. 

Oil  and  gas  exploration  and  production  activities  are  subject  to  particular  economic  and  industry-specific  operational  risks,  some  of  which  are 
beyond our control, such as production, equipment and transportation risks, as well as natural hazards and other uncertainties, including those relating to 
the physical characteristics of onshore and offshore oil or natural gas fields. Our operations may be curtailed, delayed or cancelled due to bad weather 
conditions, mechanical difficulties, shortages or delays in the delivery of equipment, compliance 

23 

with  governmental  requirements,  fire,  explosions,  blow-outs,  pipe  failure,  abnormally  pressured  formations,  and  environmental  hazards,  such  as  oil 
spills, gas leaks, ruptures or discharges of toxic gases. In addition, we operate in politically sensitive areas where the native population has interests that 
from time to time may conflict with our production or development objectives. If these risks materialize, we may suffer substantial operational losses 
and disruptions to our operations and harm to our reputation. Additionally, if any operational incident occurs that affects local communities and ethnic 
communities in nearby areas, we will need to incur in additional costs and expenses in order to return affected areas to normality and to compensate for 
any damages we may cause. These additional costs may have a negative impact on the profitability of the projects we may decide to undertake. Drilling 
may be unprofitable, not only with respect to dry wells, but also with respect to wells that are productive but do not produce sufficient revenues to return 
a profit after drilling, operating and other costs are taken into account. 

Furthermore, historically our results have been subject to seasonal fluctuations of demand during the year, in the case of natural gas, particularly 
as  a  result  of  increased  demand  during  the  colder  winter  months.  During  2018,  mainly  due  to  the  increase  in  the  natural  gas  supply  in  the  domestic 
market, and also taking into account that GDP decline had a negative impact in demand, forced us to reduce natural gas output thorough the temporary 
stop of certain wells gas production, as well as the reinjection of the hydrocarbon. Based on this new scenario, and new regulations and agreements, 
domestic  gas  prices  were  negatively  impacted.  See  “Item  5.  Operating  and  Financial  Review  and  Prospects—Factors  Affecting  Our 
Operations—Seasonality”  and  “Item  4.  Information  on  the  Company—Legal  and  Regulatory  Framework  and  Relationship  with  the  Argentine 
Government—Market Regulation—Natural Gas—Tariffs.” 

We  could  be  subject  to  fluctuations  in  non-winter  season  in  our  sales  volumes  and  consequently  our  level  of  natural  gas  production  could  be 

negatively affected potentially resulting in market prices lower than expected, thus affecting our result of operations and financial conditions. 

Our acquisition of exploratory or productive acreage and crude oil and natural gas reserves is subject to heavy competition. 

We face intense competition in bidding for crude oil and natural gas production areas, especially those areas with the most attractive crude oil and 
natural gas reserves or prospects. As a result, the conditions under which we would be access new exploratory or productive areas could be adversely 
affected. 

Our  business  plan  includes  future  drilling  activities  for  unconventional  oil  and  gas  reserves,  such  as  shale  oil  and  gas  extraction,  and  if  we  are 
unable  to  successfully  acquire  and  use  the  necessary  new  technologies  and  other  support  as  well  as  obtain  financing  and  venture  partners,  our 
business may be adversely affected. 

Our ability to execute and carry out our business plan depends upon our ability to obtain financing at a reasonable cost and on reasonable terms. 
We have identified drilling locations and prospects for future drilling opportunities of unconventional oil and gas reserves, such as the shale oil and gas 
in the Vaca Muerta formation. These drilling locations and prospects represent a part of our future drilling plans. Our ability to drill and develop these 
locations depends on a number of factors, including seasonal conditions, regulatory approvals, negotiation of agreements with third parties, commodity 
prices,  costs,  access  to  and  availability  of  equipment,  services  and  personnel  and  drilling  results.  In  addition,  the  drilling  and  exploitation  of 
unconventional  oil  and  gas  reserves  depends  on  our  ability  to  acquire  the  necessary  technology  and  hire  personnel  and  other  support  needed  for 
extraction  or  obtain  financing  and  venture  partners  to  develop  such  activities.  Furthermore,  in  order  to  implement  our  business  plan,  including  the 
development  of  our  oil  and  natural  gas  exploration  activities  and  the  development  of  refining  capacity  sufficient  to  process  increasing  production 
volumes,  we  will  need  to  raise  significant  amounts  of  debt  capital  in  the  financial and  capital  markets.  We  cannot  guarantee  that  we  will  be  able  to 
obtain the necessary financing or obtain financing in the international or local financial markets at reasonable cost and on reasonable terms to implement 
our  new  business  plan  or  that  we  would  be  able  to  successfully  develop  our  oil  and  natural  gas  reserves  and  resources  (mainly  those  related  to  our 
unconventional oil and gas business plan). Because of these uncertainties, we cannot give any assurance as to the timing of these activities or that they 
will  ultimately  result  in  the  realization  of  proved  reserves  or  meet  our  expectations  for  success,  which  could  adversely  affect  our  production  levels, 
financial condition and results of operations. 

We may not have sufficient insurance to cover all the operating hazards to which we are subject. 

As discussed under “—Oil and gas activities are subject to significant economic, environmental and operational risks and to seasonal fluctuation 
of demand” and “—We may incur significant costs and liabilities related to environmental, health and safety matters,” our exploration and production 
operations are subject to extensive economic, operational, regulatory and legal risks. We maintain insurance covering us against certain risks inherent in 
the  oil  and  gas  industry  in  line  with  industry  practice,  including  loss  of  or  damage  to  property  and  equipment,  control-of  well  incidents,  loss  of 
production or income incidents, removal of debris, sudden and accidental seepage pollution, contamination and clean up and third-party liability claims, 
including  personal  injury  and  loss  of  life,  among  other  business  risks.  However,  our  insurance  coverage  is  subject  to  deductibles  and  limits  that  in 
certain  cases  may  be  materially  exceeded  by  our  liabilities.  In addition,  certain  of  our  insurance  policies  contain  exclusions  that  could  leave  us  with 
limited coverage in certain events. See “Item 4. 

24 

Information  on  the  Company—Insurance.”  In  addition,  we  may  not  be  able  to  maintain  adequate  insurance  at  rates  or  on  terms  that  we  consider 
reasonable or acceptable or be able to obtain insurance against certain risks that materialize in the future. If we experience an incident against which we 
are not insured, or the costs of which materially exceed our coverage, it could have a material adverse effect on our business, financial condition and 
results of operations. 

Argentine oil and gas production concessions and exploration permits are subject to certain conditions and may be cancelled or not renewed. 

As modified by Law No. 27,007, the Hydrocarbons Law provides for oil and gas concessions to remain in effect for 25 years as from the date of 
their award, 35 years for unconventional concessions and 30 years for offshore concessions. It further provides that concession terms may be extended 
for  periods  of  up  to  10  years  each.  The  authority  to  extend  the  terms  of  current  and  new  permits,  concessions  and  contracts  has  been  vested  in  the 
governments of the provinces in which the relevant area is located (and the federal government in respect of offshore areas beyond 12 nautical miles). In 
order  to  be  eligible  for  an  extension  of  a  concession,  under  the  modifications  of  Law  No. 27,007,  concessionaires  must  (i) have  complied  with  their 
obligations, (ii) be producing hydrocarbons in the concession under consideration and (iii) submit an investment plan for the development of such areas 
as requested by the competent authorities up to a year prior to the termination of each term of the concession. 

Our  extension  of  concessions  includes,  among  others,  certain  level  of  investment  and  activity commitment  in  certain  periods.  Non-compliance 
with the obligations and standards set out under the Hydrocarbons Law or agreements with the competent authorities, as applicable, may also result in 
the  imposition  of  fines  and  in  the  case  of  material  breaches,  following  the  expiration  of  applicable  cure  periods,  the  revocation  of  the  concession  or 
permit. 

We  cannot  provide  assurances  that  any  of  our  concessions  will  be  extended  as  a  result  of  the  consideration  by  the  relevant  authorities  of  the 
investment plans we would submit in the future for the development of the areas as of the date of requesting the extension periods for our relevant areas, 
or other requirements will not be imposed on us in order to obtain extensions as of the date of expiration. Additional royalty payments of 3%, up to a 
maximum  of  18%,  are  provided  for  in  extensions  under  Law  No. 27,007.  The  termination  of,  or  failure  to  obtain  the  extension  of,  a  concession  or 
permit, or its revocation, could have a material adverse effect on our business and results of operations. 

We may incur significant costs and liabilities related to environmental, health and safety matters. 

Operations in the oil and gas industry in which we participate, including those related to our mining and use of sand for purposes of our oil and 
gas operations, are subject to a wide range of environmental, health and safety laws and regulations in the countries in which we operate. These laws 
and regulations have a substantial impact on our operations and those of our subsidiaries and could result in material adverse effects on our financial 
position  and  results  of  operation.  A  number  of  events  related  to  environmental,  health  and  safety  matters,  including  changes  in  applicable  laws  and 
regulations,  adverse  judicial  or  administrative  interpretations  of  such  laws  and  regulations,  changes  in  enforcement  policy,  the  occurrence  of  new 
litigation or development of pending litigation, and the development of information concerning these matters, could result in new or increased liabilities, 
capital expenditures, reserves, losses and other impacts that could have a material adverse effect on our financial condition and results of operations. For 
instance,  on  October  2018,  we  had  a  major  spill  in  the  area  of  Bandurria  Sur  caused  by  a  blowout  (decontrol  of  well),  see  “Item  4.  Upstream 
overview—Exploration  &  Production  Activity  in  Argentina—Unconventional  Region—Bandurria  Sur”.  In  addition,  the  Company’s  sand  mining 
operations and hydraulic stimulation may result in silica-related health issues and litigation that could have a material adverse effect on the Company in 
the future. See “Item 8. Financial Information—Legal Proceedings” and “Item 4. Information on the Company—Legal and Regulatory Framework and 
Relationship with the Argentine Government—Argentine Environmental Regulations.” 

Environmental, health and safety regulation and jurisprudence in Argentina is developing at a rapid pace and no assurance can be provided that 
such developments will not increase our cost of doing business and liabilities, including with respect to drilling and exploitation of our unconventional 
oil and gas reserves. In addition, due to concern over the risk of climate change, a number of countries have adopted, or are considering the adoption of, 
new regulatory requirements to reduce greenhouse gas emissions, such as carbon taxes, increased efficiency standards or the adoption of cap and trade 
regimes. Argentina recently issued new rules which began to phase-in more stringent regulations to lower the amount of sulfur contained in diesel and 
gasoline  fuels  that  will  result  in  an  increase  in  our  investments  and  relative  costs  for  such  production  in  2019  and  following  years,  thus  potentially 
affecting  our  results  of  operations  depending  on  the  future  prices  of  fuels.  Furthermore,  if  additional  requirements  were  adopted  in  Argentina,  these 
requirements could make our products more expensive as well as shift hydrocarbon demand toward relatively lower-carbon sources such as renewable 
energies. 

Furthermore,  water  is  an  essential  component  of  both  the  drilling  and  hydraulic  fracturing  processes.  Consequently,  the  Company  regularly 
disposes  of  the  fluids  produced  from  oil  and  gas  production  operations  directly  or  through  the  use  of  third  party  vendors.  Increased  regulation  or 
limitations to the use of water for our operations, or increased scrutiny or limitations on the injection of produced water through injection wells (which 
could also result in increased litigation), could adversely affect our operation and our financial condition.

We may be responsible for significant costs and liabilities depending on the outcome of the reorganization proceedings involving our YPF Holdings 
subsidiaries and the alter ego claims filed by the Liquidating Trust. 

As discussed in Note 27 to the Audited Consolidated Financial Statements, on June 17, 2016, Maxus Energy Corporation, Tierra Solutions Inc., 
Maxus  International  Energy  Company,  Maxus  (US)  Exploration  Company  and  Gateway  Coal  Company  (collectively,  the  “Maxus  Entities”), 
subsidiaries of YPF Holdings, Inc., filed for reorganization proceedings in Wilmington, Delaware under Chapter 11 of the U.S. Bankruptcy Code. In 
conjunction  with  those  proceedings,  the  Maxus  Entities  entered  into  an  agreement  with  YPF  along  with  its  subsidiaries  YPF  Holdings  Inc.,  CLH 
Holdings Inc., YPF International S.A. and YPF Services USA Corp (collectively, the “YPF Entities”) to settle any and all claims held by Maxus against 
the YPF Entities, including any alter ego claims, all of which claims the YPF Entities believe are without merit, and to release the YPF entities of any 
and all claims held by the Maxus Entities (the “Agreement”). 

The  Agreement  provided  for  a  payment  of  U.S.$  130 million  to  the  Maxus  Entities  (“Settlement  Payment”)  and  for  the  provision  of  a 

U.S.$63.1 million debtor-in-possession loan (“DIP Loan”) by YPF Holdings Inc. 

However, on March 28, 2017 the Maxus Entities and the Creditors’ Committee submitted an alternative restructuring plan (the “Alternative Plan”) 
which does not include the Agreement with the YPF Entities. Under the Alternative Plan, a Liquidating Trust may submit alter ego claims and any other 
claim belonging to the insolvent’s estate against the Company and the YPF Entities. The liquidating trust would be financed by Occidental Chemical 
Corporation in its capacity as creditor of the Maxus Entities. As YPF did not approve such Alternative Plan and the Alternative Plan did not contemplate 
the implementation of the originally submitted Agreements, on April 10, 2017 YPF Holdings, Inc. sent a note informing that this situation constituted an 
event of default under the loan granted under the Agreement with YPF and the YPF Entities. 

Together with the approval of the financing offered by Occidental under the Alternative Plan, the Judge ordered the repayment of the outstanding 

amounts (approximately U.S.$ 12.2 million) under the terms of the DIP Loan, which were subsequently received. 

On May 22, 2017, the Bankruptcy Court of the District of Delaware issued an order confirming the Alternative Plan submitted by the Creditors’ 
Committee  and  the  Maxus  Entities.  The  effective  date  of  the  Alternative  Plan  was  July 14,  2017,  as  the  conditions  set  forth  in  Article  XII.B  of  the 
Alternative Plan were met. On July 14, 2017, the Maxus Energy Corporation Liquidating Trust (the “Liquidating Trust”) was created. 

On June 14, 2018, the Liquidating Trust filed a lawsuit against the Company, YPF Holdings, CLH Holdings, Inc., YPF International and other 
companies not-related to YPF, claiming alleged damages in an amount up to US$ 14 billion, principally in connection with alleged claims purportedly 
related to corporate restructuring transactions the Company engaged in several years ago (the “Claim”). The lawsuit was filed before the United States 
Bankruptcy Court for the District of Delaware. 

On October 19, 2018, the Company, together with the other companies of the Group that are part of the Claim, filed a motion requesting dismissal 

of the Claim (“Motion to Dismiss”). 

On November 21, 2018, the Liquidating Trust filed its objection to the Motion to Dismiss filed by the Company together with the other companies 

of the Group that are part of the Claim, and to the one filed by the companies not related to YPF and which are part of the Claim. 

On December 10, 2018, the Company, together with the other companies of the Group that are part of the Claim, exercised their right of reply 

regarding the presentation made by the Liquidating Trust 

On January 22, 2019, the hearing regarding the Motion to Dismiss was held in the Bankruptcy Court. 

On February 15, 2019, the Bankruptcy Court ordered the dismissal of the Motions to Dismiss filed by the Company, together with the other Group 

companies and the other defendant companies not related to YPF. 

On March 1, 2019, the Company, together with the other companies of the Group that are part of the Claim, filed an appeal to the resolution dated 

February 15, 2019.

As described in Note 27 to the Audited Consolidated Financial Statements, according to the preliminary status of the lawsuit, the complexity of 
the  demand  and  the  evidence  that  has  to  be  submitted  by  both  parties,  the  Company  will  continuously  reevaluate  the  evolution  of  the  described 
circumstances as they happen and its impact on the results and the financial condition of the Company. 

Depending  on  the  final  outcome  of  these  matters,  including  the  alter  ego  claims,  our  financial  condition  and  results  of  operation  could  be 

materially and adversely affected. See “Item 8. Financial Information—Legal Proceedings.” 

We face risks relating to certain legal proceedings. 

As  described  under  “Item  8.  Financial  Information—Legal  Proceedings,”  we  are  party  to  a  number  of  labor,  commercial,  civil,  tax,  criminal, 
environmental  and  administrative  proceedings  that,  either  alone  or  in  combination  with  other  proceedings,  could,  if  resolved  in  whole  or  in  part 
adversely  to  us,  result  in  the  imposition  of  material  costs,  fines,  judgments  or  other  losses.  While  we  believe  that  we  have  provisioned  such  risks 
appropriately  based  on  the  opinions  and  advice  of  our  external  legal  advisors  and  in  accordance  with  applicable  accounting  rules,  certain  loss 
contingencies,  particularly  those  relating  to  environmental  matters,  are  subject  to  change  as  new  information  develops  and  it  is  possible  that  losses 
resulting from such risks, if proceedings are decided in whole or in part adversely to us, could significantly exceed any accruals we have provided. 

In addition, we may be subject to undisclosed liabilities related to labor, commercial, civil, tax, criminal or environmental contingencies incurred 
by  businesses  we  acquire  as  part  of  our  growth  strategy,  that  we  may  not  be  able  to  identify  or  that  may  not  be  adequately  indemnified  under  our 
acquisition agreements with the sellers of such businesses, in which case our business, financial condition and results of operation may be materially and 
adversely affected. 

Our business depends to a significant extent on our production and refining facilities and logistics network. 

Our oil and natural gas field facilities, refineries and logistics network are our principal production facilities and distribution network on which a 
significant  portion  of  our  revenues  depends.  Although  we  insure  our  properties  on  terms  we  consider  prudent  and  have  adopted  and  maintain  safety 
measures,  any  significant  damage,  accident  or  other  production  stoppage  at  our  facilities  or  network  could  materially  and  adversely  affect  our 
production capabilities, financial condition and results of operations. 

For instance, on April 2, 2013, our facilities in the La Plata refinery were hit by a severe and unprecedented storm, recording over 400 mm of 
rainfall. The rainfall set a new record for the area and disrupted refinery systems, causing a fire that affected the Coke A and Topping C units in the 
refinery. This incident temporarily affected the crude processing capacity of the refinery, which had to be stopped entirely during certain days. 

In addition, on March 21, 2014, a fire occurred at the Cerro Divisadero crude oil treatment plant, located 20 kilometers from the town of Bardas 
Blancas  in  the  province  of  Mendoza.  The  Cerro  Divisadero  plant,  which  has  six  tanks,  four  of  which  are  for  processing  and  two  are  for  dispatch  of 
treated crude oil, concentrates the production of ten fields in the Malargue area. This constitutes a daily production of approximately 9,200 barrels of oil 
as of the date of the incident. The new oil treatment plant was put into production in December 2016. 

We could be subject to organized labor action. 

Our operations have been affected by organized work disruptions and stoppages in the past and we cannot assure you that we will not experience 
them  in  the  future,  which  could  adversely  affect  our  business  and  revenues,  especially  in  the  context  of  activity  reduction.  Labor  demands  are 
commonplace in Argentina’s energy sector and unionized workers have blocked access to and damaged our plants in the recent past. Our operations 
were affected occasionally by labor strikes  in recent years. See “—We are exposed to the effects of fluctuations in the prices  of oil, gas and refined 
products.” and “Item 5. Operating and Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions.” 

We may not be able to pay, maintain or increase dividends. 

On April 29, 2016, our shareholders approved a dividend of Ps. 889 million (Ps. 2.26 per share or ADS), which was paid during July 2016. On April 28, 
2017, our shareholders approved a dividend of Ps. 716 million (Ps.1.82 per share or ADS), which was paid during December 2017. On April 27, 2018, 
our  shareholders  approved  a  dividend  of  Ps.  1,200 million  (Ps.3.05  per  share  or  ADS),  which  was  authorized  and  paid  during  December  2018.  On 
March 7, 2019, our Board of Directors proposed the creation of a reserve for dividend of Ps. 4,800 million. Our 

27 

next  shareholder’s  meeting,  to  be  held  on  April 26,  2019,  will  consider  this  proposal.  Notwithstanding  the  foregoing,  our  ability  to  pay,  maintain  or 
increase dividends  is based  on many  factors, including our  net income, capital expenditures required under our investment  plans, future debt service 
payments, working capital needs, legal or contractual restrictions, and general economic and financial conditions. A change in any of these factors could 
affect our ability to pay, maintain or increase dividends, and the exact amount of any dividend paid may vary from year to year. 

Our performance is largely dependent on recruiting and retaining key personnel 

Our  current  and  future  performance,  the  successful  implementation  of  our  strategy  and  the  operation  of  our  business  are  dependent  upon  the 
contributions  of  our  senior  management  and  our  highly  skilled  team  of  engineers  and  other  employees.  Our  ability  to  continue  to  rely  on  these  key 
individuals is dependent on our success attracting, training, motivating and retaining key management and commercial and technical personnel with the 
necessary skills and experience. There is no assurance that we will be successful in retaining and attracting key personnel and the replacement of any 
key personnel who were to leave could be difficult and time consuming. 

The Expropriation Law provides that the National Executive Office, by itself or through an appointed public entity, shall exercise all the political 
rights associated with the shares subject to expropriation until the transfer of political and economic rights to the provinces that compose the National 
Organization  of  Hydrocarbon  Producing  States  is  completed.  Consequently,  the  Argentine  government  has  the  majority  of  votes  which  allows  it  to 
appoint  the  majority  of  members  of  our  board  of  directors  at  the  General  Shareholder’s  meeting.  See  “—The  Argentine  Republic  owns  51%  of  the 
shares of the Company” and “—Our business is largely dependent upon economic conditions in Argentina.” The loss of the experience and services of 
key personnel or the inability to recruit suitable replacements or additional staff could have a material adverse effect on our business, financial condition 
and our results of operations. 

We could be subject to information technology system failures, network disruptions, and breaches in data security which could negatively affect our 
business, financial position, results of operations, and cash flows. 

As dependence on digital technologies is expanding, cyber incidents, including deliberate attacks or unintentional events have been increasing. 
Computers and telecommunication systems are used to conduct our exploration, development and production activities and have become an integral part 
of  our  business.  We  use  these  systems  to  analyze  and  store  financial  and  operating  data  and  to  communicate  internally  and  with  outside  business 
partners. Cyber-attacks could compromise our computer and telecommunications systems and result in disruptions to our business operations or the loss 
of  our  data.  In  addition,  computers  control  oil  and  gas  production,  processing  equipment,  and  distribution  systems  and  are  necessary  to  deliver  our 
production to market. 

Although we are continuously increasing our security policy to the industrial systems, reinforcing the defenses in case of denial of service and 
increasing the monitoring of suspicious activities, our technologies, systems, networks, and those of our business partners have been and may continue 
to  be  the  target  of  cyber-attacks  or  information  security  breaches,  which  could  lead  to  disruptions  in  critical  systems  (for  example,  SCADAs,  DCS 
Systems), unauthorized release of confidential or protected information, corruption of data or other disruptions of our business operations. In addition, 
certain cyber incidents, such as surveillance, may remain undetected for an extended period. 

As cybersecurity threats continue to evolve, we may be required to expend additional resources to continue to modify or enhance our protective 
measures or to investigate or remediate any cybersecurity or information technology infrastructure vulnerabilities. During the second half of 2018, in 
accordance  with  international  standards,  we  have  organized  and  implemented  a  Cyber  Risk  Management  Center  and  a  Computer  Security  Incident 
Response Team to monitor and mitigate cyber security threats. 

We have also updated our internal cyber incident response procedures and processes, as well as performed on the last quarter of 2018 a major 

cyber-tabletop exercise that was part of the cyber security awareness program. 

The  Company’s  reputation  is  an  important  corporate  asset.  An  operating  incident,  significant  cybersecurity  disruption  or  other  similar  adverse 
event, may have a negative impact on our reputation, which in turn could make it more difficult for us to compete successfully for new opportunities or 
could reduce consumer demand for the company’s branded products. 

During 2018, we have been the target of many attempted attacks and were exposed to malware infections like other companies in the industry, 
which did not result in a significant loss or a negative impact in our operations. There can be no assurance that the Company will not incur such losses in 
the  future.  The  Company’s risk  and  exposure  to these matters  cannot be  fully  calculated  nor mitigated  because  of, among other  things,  the  evolving 
nature of these threats. 

28 

A  cyber-attack  involving  our  information  systems  and  related  infrastructure,  or  those  of  our  business  partners,  could  disrupt  our  business  and 

negatively impact our operations in a variety of ways, including but not limited to: 

•

•

•

•

•

unauthorized access to seismic data, reserves information, strategic information, or other sensitive or proprietary information could have a 
negative impact on our ability to compete for oil and gas resources; 

data corruption or operational disruption of production-related infrastructure could result in a loss of production, or accidental discharge; 

disruption of  our operations, communications,  or processing of  transactions or the loss of, or damage to, sensitive information,  facilities, 
infrastructure and systems which are essential to our business and operations which, in turn, could have a material adverse effect on our 
business, financial position, results of operations, and cash flows; 

a cyber-attack on a service provider could result in supply chain disruptions, which could delay or halt our major development projects; 

a cyber-attack on our accounting or accounts payable systems could expose us to liability to employees and third parties if their sensitive 
personal information is obtained. 

Our derivative risk management activities could result in financial losses. 

As  of  the  date  of  this  annual  report,  the  Company,  through  our  subsidiary  Metrogas,  has  entered  into  derivative  financial  instruments  with 
quotation in active markets (contracts of future exchange rate in dollars). We could be exposed to adverse variations in the price of the assets underlying 
the derivative contract, which would in turn affect our results of operations and financial condition. In addition, any failure in the performance of their 
obligations by our counterparties to any of these agreements could also have a material adverse effect on the Company’s results of operations. 

Our actual production could differ materially from our forecasts. 

From time to time, we provide forecasts of expected quantities of future oil and gas production and other financial and operating results. These 
forecasts are based on a number of estimates and assumptions, including that none of the risks associated with our oil and gas operations summarized in 
this “Item 3. Key Information—Risk Factors” occur. Production forecasts,  specifically,  are based on assumptions such as expectations of  production 
from existing wells, the level and outcome of future drilling activity, the level of gas demand, and the absence of facility or equipment malfunctions, 
adverse weather effects, or downturns in commodity prices or significant increases in costs, which could make certain drilling activities or production 
uneconomical.  Should  any  of  these  estimates  prove  inaccurate,  or  should  our  development  plans  change,  actual  production  could  be  materially  and 
adversely affected. 

We have limited control over the day to day activities carried out on properties which we do not operate. 

Some of the properties in which we have an interest are operated by other companies and involve third-party working interest owners. As a result, 
we  have  limited  ability  to  influence  or  control  the  day  to  day  operations  of  these  companies  and  third-parties,  including  their  compliance  with 
environmental, safety and other regulations, which, in turn, could have a material adverse effect on our business, financial position, results of operations, 
cash flows and/or our reputation. 

We could be affected by violations to anticorruption, anti-bribery, anti-money laundering and other national and international regulations. 

We are subject to anticorruption, anti-bribery, anti-money laundering and other national and international regulations. We are required to comply 
with the regulations of Argentina and various jurisdictions where we conduct operations. Although we have internal policies and procedures designed to 
ensure  compliance  with  applicable  anti-fraud,  anti-bribery  and  anti-corruption  laws  and  sanctions  regulations,  potential  violations  of  anti-corruption 
laws  could  be  identified  on  occasion  as  part  of  our  compliance  and  internal  control  processes.  In  case  such  issues  arise,  we  plan  to  attempt  to  act 
promptly to learn relevant facts, conduct appropriate due diligence, and take any appropriate remedial action to address the risk. Given the size of our 
operations and the complexity of the production chain, there can be no assurance that our internal policies and procedures will be sufficient to prevent or 
detect all  inappropriate practices,  fraud or  violations  of  law  by our  employees, directors, officers, partners, agents and service providers  or that  such 
persons will not  take  actions in  violation  of our  policies  and  procedures  (or otherwise  in violation of  the  relevant anti-corruption  laws  and sanctions 
regulations) for which we or they may be ultimately held responsible. Violations of anti-bribery and anti-corruption laws and sanctions regulations could 
have a material adverse effect on our business, reputation, results of operations and financial condition. In addition, we may be subject to one or more 
enforcement actions, investigations and proceedings by authorities for alleged infringements of these laws. These proceedings may result in penalties, 
fines,  sanctions  or  other  forms  of  liability  and  could  have  a  material  adverse  effect  on  our  reputation,  business,  financial  condition  and  results  of 
operations. 

29 

If we fail to comply with the covenants set forth in our credit agreements and indentures, or upon the occurrence of a change of control, we may be 
required to repay our debt. 

Under the terms of our credit agreements and indentures, if we fail to comply with the covenants set forth thereunder or if we fail to cure any 
breach thereof during a specified period of time, we will be in default of our obligations, which in turn would limit our capacity of borrowing. To the 
extent  we  default  on  any  of  our  obligations,  we  would  expect  to  actively  pursue  formal  waivers  from  the  corresponding  counterparties  to  these 
agreements,  in  order  to  avoid  the  acceleration  of  any  amounts  owed  thereunder.  However,  if  the  corresponding  waivers  are  not  timely  obtained,  in 
accordance with the terms of our credit and indentures certain creditors may declare the principal and accrued interest on amounts owed to them as due 
and immediately payable, resulting in acceleration of other outstanding debt due to cross default provisions, which in turn could have a material adverse 
effect on our business, financial condition and results of operations. 

In addition, upon the occurrence of a change of control, we may be required to make an offer to purchase certain outstanding notes at a price of 
101% of their principal amount plus accrued and unpaid interest, and our other debt may be subject to mandatory prepayment. Our source of funds for 
any such mandatory prepayment will be available cash or other sources, including borrowings, sales of assets or sales of equity. The sources of cash 
may not be adequate to permit us to immediately prepay our indebtedness upon a change of control, which in turn may result in an event of default 
under certain agreements governing our indebtedness. 

Risks Relating to Our Class D Shares and ADSs 

The market price for our shares and ADSs may be subject to significant volatility 

The market price of our ordinary shares and ADSs may fluctuate significantly due to a number of factors, including, among others, our actual or 
anticipated results of operations and financial condition; speculation over the impact of the Argentine government as our controlling shareholder on our 
business and operations, investor perceptions of investments relating to Argentina and political and regulatory developments affecting our industry or 
the  Company.  In  addition,  recent  regulatory  and  policy  developments  in  Argentina,  including  the  passage  of  the  Expropriation  Law,  as  well  as  the 
litigation  of  the  Argentine  government  with  Holdout  Bondholders  (see  “—Risks  Relating  to  Argentina—Our  business  is  largely  dependent  upon 
economic conditions in Argentina”), have led to considerable volatility in the market price of our shares and ADSs. For example, the price of our ADSs 
has varied from U.S.$54.58 on January 5, 2011 to U.S.$ 9.57 on November 16, 2012. The price hit a high closing price of U.S.$ 36.99 on July 1, 2014, 
but subsequently fell to U.S.$ 12.83 on January 20, 2016. During 2017 the price of our ADSs reached a maximum of U.S.$ 26.16 but, mainly due to the 
Argentine economic conditions, decreased to a minimum value of U.S.$ 12.31 on December 24, 2018. As of March 28, 2019, our ADSs reached a price 
of 13.69 U.S.$. See “Item 9. The Offer and Listing.” We cannot assure you that concerns about factors that could affect the market price of our ordinary 
shares as previously mentioned may have a material adverse effect on the trading values of our securities. 

Certain strategic transactions require the approval of the holder of our Class A shares or may entail a cash tender offer for all of our outstanding 
capital stock. 

Under our by-laws, the  approval of the Argentine government,  the sole holder of our  Class A  shares,  is required to undertake certain strategic 
transactions,  including  a  (i)  merger;  (ii)  the  transfer  to  third  parties  of  all  the  exploitation  rights  granted  to  YPF  pursuant  to  the  Hydrocarbons  Law, 
applicable  regulations  thereunder  or  the  Privatization  Law-  if  such  transfer  would  result  in  the  total  suspension  of  the  Company’s  exploration  and 
production activities-;(iii) the voluntary dissolution of the Company, (iv) the transfer of the legal or fiscal domicile of the Company outside Argentina. 
This approval would also be necessary in connection with an acquisition that would result in the purchaser holding 15% or more of our capital stock, 
20% or more of the outstanding Class D shares, or a majority of our capital stock. 

According  to  our  by-laws,  the  transactions  described  in  (iii)  and  (iv)  above  also  require  the  prior  approval  of  the  Argentine  congress  through 

enactment of a law. 

In addition, our by-laws also provide that in order to carry out an acquisition that results in the purchaser holding 15% or more of our capital stock 
or 20% or more of the outstanding Class D shares, such purchaser would be required to make a public tender offer for all of our outstanding shares and 
convertible  securities,  which  could  discourage  certain  investors  from  acquiring  significant  stakes  in  our  capital  stock.  See  “Item  10.  Additional 
Information—Certain Provisions Relating to Acquisitions of Shares”. 

Restrictions on the movement of capital out of Argentina may impair your ability to receive dividends and distributions on, and the proceeds of any 
sale of, the Class D shares underlying the ADSs. 

The  government  is  empowered,  for  reasons  of  public  emergency,  as  defined  in  Article  1  of  Law  No. 25,561,  to  establish  the  system  that  will 
determine the exchange rate between the peso and foreign currency and to impose exchange regulations. Although the transfer of funds abroad in order 
to pay dividends currently does not require Argentine Central Bank approval, restrictions on the movement of capital to and from Argentina may, if 
imposed, impair or prevent the conversion of dividends, distributions, or the proceeds from any sale of Class D shares, as the case may be, from pesos 
into U.S. dollars and the remittance of the U.S. dollars abroad. 

30 

Under  the  terms  of  our  deposit  agreement  with  the  depositary  for  the  ADSs,  the  depositary  will  convert  any  cash  dividend  or  other  cash 
distribution we pay on the shares underlying the ADSs into U.S. dollars, if it can do so on a reasonable basis and can transfer the U.S. dollars to the 
United  States.  If  this  conversion  is  not  possible  for  any  reason,  including  regulations  of  the  type  described  in  the  preceding  paragraph,  the  deposit 
agreement  allows  the  depositary  to  distribute  the  foreign  currency  only  to  those  ADR  holders  to  whom  it  is  possible  to  do  so.  If  the  exchange  rate 
fluctuates significantly during a time when the depositary cannot convert the foreign currency, you may lose some or all of the value of the dividend 
distribution. 

We are traded on more than one market and  this may result in price variations; in addition, investors may not be able to easily move shares for 
trading between such markets. 

Trading  in  the  ADSs  or  Class D  Shares  underlying  ADSs  in  the  United  States  and  Argentina,  respectively,  will  use  different  currencies  (U.S. 
dollars on the New York Stock Exchange (“NYSE”) and Argentine pesos on the Mercado de Valores de Buenos Aires (“S&P MERVAL”), and take 
place at different times (resulting from different trading platforms, different time zones, different trading days and different public holidays in the United 
States and Argentina). The trading prices of the Class D Shares underlying ADSs on these two markets may differ due to these and other factors. Any 
decrease in  the price of the Class D Shares underlying ADSs on the S&P MERVAL could cause a decrease in the trading price of the ADSs on the 
NYSE. Investors could seek to sell or buy the Class D Shares underlying ADSs to take advantage of any price differences between the markets through 
a practice referred to as “arbitrage.” Any arbitrage activity could create unexpected volatility in both our share prices on one exchange, and the ADSs 
available  for  trading  on  the  other  exchange.  In  addition,  holders  of  ADSs  will  not  be  immediately  able  to  surrender  their  ADSs  and  withdraw  the 
underlying Class D Shares for trading on the other market without effecting necessary procedures with the depositary. This could result in time delays 
and additional cost for holders of ADSs. 

Under Argentine law, shareholder rights may be different from other jurisdictions. 

Our corporate affairs are governed by our by-laws and by Argentine corporate law, which differ from the legal principles that would apply if we 
were incorporated in a jurisdiction in the United States or in other jurisdictions outside Argentina. In addition, rules governing the Argentine securities 
markets are different and may be subject to different enforcement in Argentina than in other jurisdictions. 

Actual or anticipated sales of a substantial number of Class D shares could decrease the market prices of our Class D shares and the ADSs. 

Sales  of  a  substantial  number of  Class D  shares  or ADSs  by any present or  future relevant shareholder could decrease the trading price of our 

Class D shares and the ADSs. 

You may be unable to exercise preemptive, accretion or other rights with respect to the Class D shares underlying your ADSs. 

Holders  of  ADSs  may  not  be  able  to  exercise  the  preemptive  or  accretion  rights  relating  to  the  shares  underlying  the  ADSs  (see  “Item  10. 
Additional Information—Preemptive and Accretion Rights”) unless a registration statement under the U.S. Securities Act of 1933 (the “Securities Act”) 
is effective with respect to those rights or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file 
a registration statement with respect to the shares relating to these preemptive rights, and we cannot assure you that we will file any such registration 
statement. Unless we file a registration statement or an exemption from registration is available, holders may receive only the net proceeds from the sale 
of their preemptive rights by the depositary or, if the preemptive rights cannot be sold, they will be allowed to lapse. As a result, U.S. holders of Class D 
shares or ADSs may suffer dilution of their interest in our company upon future capital increases. 

In  addition,  under  the  Argentine  General  Corporations  Law,  foreign  companies  that  own  shares  in  an  Argentine  corporation  are  required  to 
register  with  the  Superintendence  of  Corporations  (Inspección  General  de  Justicia)  (“IGJ”)  in  order  to  exercise  certain  shareholder  rights,  including 
voting rights. If you own our Class D shares directly (rather than in the form of ADSs) and you are a non-Argentine company and you fail to register 
with IGJ, your ability to exercise your rights as a holder of our Class D shares may be limited. 

You may be unable to exercise voting rights with respect to the Class D shares underlying your ADSs at our shareholders’ meetings. 

The  depositary  will  be  treated  by  us  for  all  purposes  as  the  shareholder  with  respect  to  the  shares  underlying  ADSs.  A  holder  of  ADRs 
representing the ADSs being held by the depositary will not have direct shareholder rights and may exercise voting rights with respect to the Class D 
shares represented by the ADSs only in accordance with the deposit agreement relating to the ADSs. There are no 

31 

provisions under Argentine law or under our by-laws that limit the exercise by ADS holders of their voting rights through the depositary with respect to 
the underlying Class D shares. However, there are practical limitations on the ability of ADS holders to exercise their voting rights due to the additional 
procedural  steps  involved  in  communicating  with  these  holders.  For  example,  holders  of  our  shares  will  receive  notice  of  shareholders’  meetings 
through publication of a notice in an official gazette in Argentina, an Argentine newspaper of general circulation and the bulletin of the Buenos Aires 
Stock  Exchange  and  will  be  able  to  exercise  their  voting  rights  by  either  attending  the  meeting  in  person  or  voting  by  proxy.  ADS  holders,  by 
comparison, will not receive notice directly from us. Instead, in accordance with the deposit agreement, we will provide the notice to the depositary. If 
we ask it to do so, the depositary will mail to holders of ADSs the notice of the meeting and a statement as to the manner in which instructions may be 
given  by  holders.  To  exercise  their  voting  rights,  ADS  holders  must  then  instruct  the  depositary  on  how  to  vote  with  regards  to  the  Class D  shares 
represented by their ADSs. Due to these procedural steps involving the depositary, the process for exercising voting rights may take longer for ADS 
holders than for holders of Class D shares,  if no such instructions are received, the depositary  shall vote the Class D  shares  represented by ADSs in 
accordance with the recommendations of the Board of Directors made to all holders of shares. 

Shareholders outside of Argentina may face additional investment risk from currency exchange rate fluctuations in connection with their holding of 
our Class D shares or the ADSs. 

We are an Argentine company and any future payments of dividends on our Class D shares will be denominated in Argentine pesos. The peso has 
historically and recently fluctuated significantly against many major world currencies, including the U.S. dollar. A devaluation of the Argentine peso 
would likely adversely affect the U.S. dollar or other currency equivalent of any dividends paid on our Class D shares and could result in a decline in the 
value of our Class D shares and the ADSs as measured in U.S. dollars. 

ITEM 4.

Information on the Company 

History and Development of YPF 

Overview 

YPF  is  a  corporation  (sociedad  anónima),  incorporated  under  the  laws  of  Argentina  for  a  limited  term.  Our  address  is  Macacha  Güemes  515, 
C1106BKK  Ciudad  Autónoma  de  Buenos  Aires,  Argentina  and  our  telephone  number  is  (011-54-11)  5441-2000.  Our  legal  name  is  YPF  Sociedad 
Anónima and we conduct our business under the commercial name “YPF.” 

We  are  Argentina’s  leading  energy  company,  operating  a  fully  integrated  oil  and  gas  chain  with  leading  market  positions  across  the  domestic 
upstream,  downstream  and  gas  and  power  segments.  Our  upstream  operations  consist  of  the  exploration,  development  and  production  of  crude  oil, 
natural gas and LPG. Our downstream operations include the refining, marketing, transportation and distribution of oil and a wide range of petroleum 
products, petroleum derivatives, petrochemicals, LPG and bio-fuels. Additionally, we are active in the gas separation and natural gas distribution sectors 
both directly and through our investments in several affiliated companies and in power generation through YPF Energía Eléctrica S.A. (“YPF EE”), a 
company that we jointly control with GE EFS Power Investments B.V. (“GE”), a subsidiary of EFS Global Energy B.V. (both corporations indirectly 
controlled by GE Energy Financial Services, Inc.) (see “Item 4. Information on the Company—Gas and Power—YPF in Power Generation.”). In 2018, 
we had consolidated revenues of Ps. 435,820 million and consolidated net profit of Ps. 38,606 million. 

Beginning  in  the  1920s  and  until  1990,  both  the  upstream  and  downstream  segments  of  the  Argentine  oil  and  gas  industry  were  effectively 
monopolies of the Argentine government. During this period, we and our predecessors were owned by the state, which controlled the exploration and 
production of oil and natural gas, as well as the refining of crude oil and marketing of refined petroleum products. In August 1989, Argentina enacted 
laws aimed at the deregulation of the economy and the privatization of Argentina’s state-owned companies, including us. Following the enactment of 
these laws, a series of presidential decrees were promulgated, which required, among other things, us to sell majority interests in our production rights to 
certain major producing areas and to undertake an internal management and operational restructuring program. 

In  November  1992,  the  Argentine  government  enacted  the  Privatization  Law  (Law  No. 24,145),  which  established  the  procedures  for  our 
privatization.  In  accordance  with  the  Privatization  Law,  in  July  1993,  we  completed  a  worldwide  offering  of  160 million  Class D  shares  that  had 
previously been owned by the Argentine government. As a result of that offering and other transactions, the Argentine government’s ownership interest 
in our capital stock was reduced from 100% to approximately 20% by the end of 1993. 

In January 1999, Repsol YPF acquired 52,914,700 Class A shares (14.99% of our shares) which were converted to Class D shares. Additionally, 
on April 30, 1999, Repsol YPF announced a tender offer to purchase all outstanding Class A, B, C and D shares (the “Offer”). Pursuant to the Offer, in 
June  1999,  Repsol  YPF  acquired  an  additional  82.47%  of  our  outstanding  capital  stock.  Repsol  YPF  acquired  additional  stakes  in  us  from  minority 
shareholders and other transactions in 1999 and 2000. 

32 

Repsol YPF owned approximately 99% of our capital stock from 2000 until 2008, when Petersen Energía (“PEISA”) acquired 15% of our capital 
stock, from Repsol YPF. On May 3, 2011, PEISA exercised an option to acquire, from Repsol YPF, shares or ADSs representing 10.0% of our capital 
stock and on May 4, 2011, Repsol YPF acknowledged and accepted such exercise. See “—Legal and Regulatory Framework and Relationship with the 
Argentine Government—The Expropriation Law” and “Item 7. Major Shareholders and Related Party Transactions,” for a detail of our current major 
shareholders. 

On  May 3,  2012,  the  Argentine  Congress  passed  the  Expropriation  Law.  Among  other  matters,  the  Expropriation  Law  provided  for  the 
expropriation of 51% of the share capital of YPF represented by an identical stake of Class D shares owned, directly or indirectly, by Repsol YPF and 
its controlled or controlling entities. The shares subject to expropriation, which have been declared of public interest, will be assigned as follows: 51% 
to the Argentine Republic and 49% to the governments of the provinces that compose the National Organization of Hydrocarbon Producing States. See 
“Item 3. Key Information—Risk Factors—Risks Relating to Argentina—The Argentine Republic owns 51% of the shares of the Company.” As of the 
date of this annual report, the transfer of the shares subject expropriation between the National Executive Office and the provinces that compose the 
National  Organization  of  Hydrocarbon  Producing  States  was  still  pending.  According  to  Article  8  of  the  Expropriation  Law,  the  distribution  of  the 
shares  among  the  provinces  that  accept  their  transfer  must  be  conducted  in  an  equitable  manner,  considering  their  respective  levels  of  hydrocarbon 
production and proved reserves. To ensure compliance with its objectives, the Expropriation Law provides that the National Executive Office, by itself 
or  through  an  appointed  public  entity,  shall  exercise  all  the  political  rights  associated  with  the  shares  subject  to  expropriation  until  the  transfer  of 
political and economic rights to the provinces that compose the National Organization of Hydrocarbon Producing States is completed. In addition, in 
accordance with Article 9 of the Expropriation Law, each of the Argentine provinces to which shares subject to expropriation are allocated must enter 
into a shareholder’s agreement with the federal government that will provide for the unified exercise of its rights as a shareholder. See “—Legal and 
Regulatory  Framework  and  Relationship  with  the  Argentine  Government—The  Expropriation  Law,”  “Item  7.  Major  Shareholders  and  Related  Party 
Transactions.” See “Item 3. Key Information—Risk Factors—Risks Relating to Our Business—We face risk relating to certain legal proceedings”. 

In  addition,  on  February 25,  2014,  the  Republic  of  Argentina  and  Repsol  reached  an  agreement  (the  “Repsol  Agreement”)  in  relation  to 
compensation for the expropriation of 200,589,525 of YPF’s Class D shares pursuant to the Expropriation Law under the Repsol Agreement. Repsol 
accepted  U.S.$5.0 billion  in sovereign  bonds  from the Republic of  Argentina  and  withdrew  judicial  and  arbitral  claims  it  had  filed,  including  claims 
against  YPF,  and  waived  additional  claims.  YPF  and  Repsol  also  executed  a  separate  agreement  (the  “Repsol  Arrangement”)  on  February 27,  2014, 
pursuant to which YPF and Repsol each withdrew, subject to certain exclusions, all present and future actions and/or claims based on causes occurring 
prior to the date of execution of Repsol Arrangement arising from the expropriation of the YPF shares owned by Repsol pursuant to the Expropriation 
Law, including the intervention and temporary possession for public purposes of YPF’s shares. YPF and Repsol agreed to withdraw reciprocal actions 
and claims with respect to third parties and/or pursued by them and to grant a series of mutual indemnities, which at the time were subject to certain 
conditions precedent. The Repsol Arrangement entered into force the day after Repsol notified YPF that the Repsol Agreement had entered into force. 
The  Repsol  Agreement  was  ratified  on  March 28,  2014  at  a  Repsol  general  shareholders’  meeting  and  approved  by  the  Argentine  Congress  by  Law 
No. 26,932 enacted by Decree No. 600/2014. On May 8, 2014, YPF was notified of the entry into force of the Repsol Agreement. As of that date, the 
expropriation pursuant to the Expropriation Law was concluded, and as a result the Republic of Argentina is definitively the owner of 51% of the capital 
stock of each of YPF and YPF GAS S.A. 

We are strongly committed to the country’s energy development and seek to lead the transformation of the industry within the context of industry 

change at an international level. 

In order to achieve our vision of being a company that generates sustainable, profitable and accessible energy for our customers, YPF’s strategy is 

based on the following pillars: 

• Extract the maximum value from conventional fields 

• Develop and achieve efficient costs in shale operations 

• Partner with leading companies worldwide 

• Expand our power generation capacity in order to become a major player in the sector 

• Maintain a financial management discipline of the corporate portfolio 

• Create a new supply chain organization in order to modernize the procurement processes, contracts and associated logistics 

•

•

Incorporate technology and innovation in all business segments to improve productivity and service to our customers 

Implement a transformation program that modernizes the company, enhances efficiency and seeks growth initiatives that support our vision 

• Reduce the company’s specific CO2 emissions in the upcoming years as part of our commitment to sustainability 

The  investment  plan  related  to  our  growth  needs  to  be  accompanied  by  an  appropriate  financial  plan,  whereby  we  intend  to  reinvest  earnings, 

search for strategic partners and raise debt financing at levels we consider prudent for companies in our industry. Consequently, 

33 

the financial viability of these investments and hydrocarbon recovery efforts will generally depend, among other factors, on the prevailing economic and 
regulatory  conditions  in  Argentina,  the  ability  to  obtain  financing  in  satisfactory  amounts  at  competitive  costs,  as  well  as  the  market  prices  of 
hydrocarbon products. See “Item 3. Key Information—Risk Factors—Risks Relating to Argentina.” and “Item 5. Factors Affecting Our Operations” for 
additional information regarding 2018 activity. 

Upstream Operations 

•

As of December 31, 2018, we held interests in 132 oil and gas fields in Argentina. According to the Ministry of Energy and Mining, in 2018 
these assets accounted for approximately 46.4% of the country’s total production of crude oil, excluding NGLs, and approximately 37.4% of 
its total natural gas production, including NGLs. 

• We had proved reserves, as estimated as of December 31, 2018, of approximately 638 mmbbl of oil, including condensates and NGLs, and 
approximately 2,481 bcf of gas, representing aggregate reserves of approximately 1,080 mmboe as of such date, compared to approximately 
480 mmbbl of oil, including condensates and NGLs, and approximately 2,520 bcf of gas, representing aggregate reserves of approximately 
929 mmboe as of December 31, 2017. 

•

In  2018,  we  produced  approximately  83  mmbbl  of  oil  (approximately  227  mbbl/d),  including  condensates,  approximately  14  mmbbl  of 
NGLs  (approximately  39  mbbl/d),  and  approximately  542  bcf  of  gas  (approximately  1,484  mmcf/d),  representing  a  total  production  of 
approximately  193  mmboe  (approximately  530  mboe/d),  compared  to  approximately  83  mmbbl  of  oil  (approximately  228  mbbl/d), 
including  condensates,  approximately  19  mmbbl  of  NGLs  (approximately  50  mbbl/d),  and  approximately  567  bcf  of  gas  (approximately 
1,556 mmcf/d), representing a total production of approximately 202 mmboe (approximately 555 mboe/d) in 2017. 

Downstream Operations 

• We are Argentina’s leading refiner with operations conducted at three wholly-owned refineries with combined annual refining capacity of 
approximately 116 mmbbl (319.5 mbbl/d). See “—Downstream—Refining division.” We also own a 50% equity interest in Refinería del 
Norte,  S.A.  (“Refinor”),  an  entity  jointly  controlled  with  and  operated  by  Petrobras  Energía  S.A.,  which  has  a  refining  capacity  of  26.1 
mbbl/d. 

•

Our  retail  distribution  network  for  automotive  petroleum  products  as  of  December 31,  2018  consisted  of  1,591  YPF-branded  service 
stations, of which we own 113 directly and through our 100%-owned subsidiary Operadora de Estaciones de Servicios S.A. (“OPESSA”), 
and we estimate we held approximately 35.8% of all gasoline service stations in Argentina. 

• We  are one  of the leading petrochemical  producers  in  Argentina and  in  the  Southern  Cone of  Latin  America, with  operations  conducted 
through our Ensenada industrial complex (“CIE”) and Plaza Huincul site. In addition, Profertil S.A. (“Profertil”), a company that we jointly 
control with Agrium Holdco Spain S.L. (“Agrium”), is one of the leading producers of urea in the Southern Cone. 

Gas and Power Operations 

• We are the largest producer of natural gas in Argentina with total natural gas sales of 14,486 mmcm in 2018. As of November 2018, our 

market share was 29.9%, according to ENARGAS. 

• We participated in eight power generation plants with an aggregate installed capacity of 1,819 MW with YPF EE, a company that we jointly 
control with GE EFS Power Investments B.V. (“GE”), a subsidiary of EFS Global Energy B.V. (both corporations indirectly controlled by 
GE Energy Financial Services, Inc). 

• We are the operator of UTE Escobar (a joint venture formed by YPF and IEASA), which operates an LNG Regasification Terminal (“LNG 
Escobar”). Additionally, the gas liquefaction services agreement was signed with the barge called “Tango FLNG”, which will operate in 
Bahía Blanca and is expected to start operating in the second quarter of 2019. See “—Gas and Power—Argentine natural gas supplies.” We 
also distribute natural gas through our subsidiary Metrogas a natural gas distribution company in the capital region and southern suburbs of 
Buenos Aires, and one of the main distributors in Argentina. During 2018, Metrogas distributed approximately 20.8 mmcm (or 733.4 mmcf) 
of natural gas per day to 2.4 million customers. See “Item 4—Information on the Company—Gas and Power—Natural Gas Distribution.”

The Argentine Market 

Argentina is the second largest producer of natural gas and the fourth largest producer of crude oil in Central and South America, based on 2017 

production, according to the 2018 edition of the BP Statistical Review of World Energy, published in June 2018. 

In response to the economic crisis of 2001 and 2002, the Argentine government, pursuant to the Public Emergency Law, established export taxes 
on certain  hydrocarbon  products.  In subsequent years,  in order  to  satisfy  growing  domestic  demand  and  abate  inflationary pressures, this  policy was 
supplemented by constraints on domestic prices, temporary export restrictions and subsidies on imports of natural gas and diesel. As a result, until 2008, 
local  prices  for  oil  and  natural  gas  products  had  remained  significantly  below  those  prevalent  in  neighboring  countries  and  international  commodity 
exchanges. 

In 2012, Argentina’s GDP experienced a slowdown, with GDP increasing 1.9% on an annual basis compared to the preceding year according to 
the methodology of calculation prevailing until March 2014. On March 27, 2014, the Argentine government announced a new method of calculating 
GDP  using  2004  as  the  base  reference  year  (as  opposed  to  1993,  which  was  the  base  reference  year  under  the  prior  method  of  calculating  GDP). 
However, on January 7, 2016 through Decree No. 55/2016, the new leadership of INDEC issued a report declaring a “national statistical emergency.” 
INDEC stated that since 2006 its administration has been irregular and due to that they revised the published data from 2005 to 2015. As a result of this 
revision, the GDP growth rate for 2013 and 2014 was revised from 2.9% to 2.4% and from 0.5% to a decline rate of 2.5%, respectively. As of the date 
of this annual report, Argentina’s provisional GDP growth rate for 2016, the provisional GDP growth rate for 2017 and the preliminary GDP growth rate 
for 2018 published by INDEC were negative 1.8%, positive 2.7% and negative 2.5%, respectively. 

Driven by economic expansion and stable domestic prices, energy demand has increased significantly during last years, outpacing energy supply 
(which,  in  the  case  of  oil,  declined).  As  a  result  of  a  high  number  of  power  outages  caused  by  the  consumption  increase,  the  Ministry  of  Energy 
requested  that  the  National  Executive  Office  declare  a  National  Electric  System  Emergency  through  December 31,  2017.  This  decree  instructs  the 
Minister of Energy to develop and propose measures and to ensure adequate power supplies. Also, the Ministry of Energy and Mining established new 
seasonal  reference  prices  for  power  and  energy  in  the  Wholesale  Electricity  Market  (“MEM”).  See  “Item  4—Legal  and  Regulatory  Framework  and 
Relationship with the Argentine Government—Market Regulation—Electricity.” 

In  2003,  Argentina’s  net  exports  of  diesel  amounted  to  approximately  1,349  mcm,  while  in  2018  its  net  imports  of  diesel  amounted  to 
approximately 2,170 mcm, according to preliminary information provided by the SGE. Significant investments in the energy sector are being carried 
out, and additional investments are expected to be required in order to support continued economic growth, as the industry is currently operating near 
full capacity. 

Demand  for  diesel  in  Argentina  exceeds  domestic  production.  In  addition,  prior  to  the  decline  in  international  oil  prices,  the  import  prices  of 
refined products have been in general substantially higher than the average domestic sales prices of such products, rendering the import and resale of 
such products less profitable. As a result, from time to time in the past, service stations experience temporary shortages and are required to suspend or 
curtail diesel sales. 

With regard to the analysis of prior periods, until recently, the applicable domestic prices of petroleum products were established for the short 
term mainly on the basis of negotiations between Producers and Refiners of the country, without keeping a direct or specific reference with respect to 
the international quotations of such products. That is, the domestic market was decoupled from the international market in terms of prices, which was 
evidenced in certain periods with movements of prices in meanings (or values) substantially different from those observed in the international market. 
Notwithstanding the foregoing, the local market started a process to achieve an orderly transition towards international prices. 

In January 2017, the Producers and Refiners reached a new agreement (the “Transitional Agreement”) for the aforementioned transition, in which 
a price path was established for the commercialization of oil in the domestic market, with the objective of achieving parity with international markets 
during the course of 2017. This took place during the last quarter of 2017, taking into account the internalization costs in the domestic market of the 
referred products, the expected margins and the demand, among other factors. After the completion of the 2017 Transitional Agreement, according to 
Argentina’s Ministry of Energy and Mining, the hydrocarbons market in Argentina became a liberalized market, and oil and fuel prices must be set by 
the  free  market  and,  thus,  fluctuate.  This  decision  formally  ended  the  transition  to  international  oil  price  parity.  Nevertheless,  due  to  various  factors 
(including, but not limited to, the abrupt variation 

36 

in the exchange rate and the increase in international prices of oil and the consequent difficulties to pass-through the corresponding variation to domestic 
prices) the intended liberalization could not be fully realized during 2018. Accordingly, we cannot guarantee that the liberalization of oil and fuel prices 
in  the  domestic  market  may  finally  operate  in  the  future  due  to  various  factors  such  as,  domestic  demand,  macroeconomic  and  political  conditions 
prevailing in Argentina or potential new regulatory or legal limitations. 

In connection with the matters set forth above, during the second quarter of 2018, the MINEM and the refining companies entered into a price 
stability agreement with a compensatory account, whereby refining companies undertook not to make changes in the prices of their products -net of fuel 
taxes- in force as of the date of the agreement, during the months of May and June. Moreover, at the beginning of June, a supplemental agreement was 
entered into, which established a Brent referent price for oil purchase transactions between refining and producing companies, and an increase in the 
final prices of fuel and gasoil as of June 2, 2018, which included the variation of tax on liquid fuels, carbon dioxide tax and the prices of biofuels in 
force at that date. 

However,  in  view  of  the  volatility  and  significant  change  in  the  variables  which  gave  rise  to  the  price  stability  agreements,  YPF  informed  the 
MINEM  of  its  decision  to  implement,  as  of  1 July,  2018,  the  commercial  policies  applicable  to  the  changes  in  the  applicable  variables,  both  for  the 
determination of its products’ sale prices and for the purchase of crude oil, in a manner consistent with the evolution of the business environment in 
general and that of customers in particular, in accordance with the regulatory framework and applicable regulations. Consequently, on June 30, 2018, 
the price stabilization agreements ceased to be in force for YPF. 

On December 6, 2018, YPF requested that the SGE set the guidelines to implement the mechanics necessary for the recovery of the margins not 
reflected in the fuel price for the term during which the price stabilization agreement was in effect. As of the date of this annual report, the Company has 
not received a response to such request.

Upstream overview 

YPF  Upstream  is  focused  on  actively  managing  the  decline  of  the  conventional  fields  and  delivering  profitable  growth  driven  by  unconventional 
projects. 

Smoothing the decline rate in conventional fields is based on reservoir management improvement, accelerated implementation of improved oil recovery 
(IOR) and enhanced oil recovery (EOR) and the deployment of technology to optimize operations in real time while reducing downtime. We plan to 
continue to de-risk projects based on recent successful results in tertiary recovery. 

38 

During recent years, we have been working in mature areas that present profitable opportunities to increase the recovery factor by employing techniques 
including  infill  wells,  extension  of  secondary  recovery,  and  tertiary  recovery  testing.  We  are  focused  on  identifying  new  opportunities  in  both  infill 
potential and improved sweep efficiency in our mature fields. These efforts are guided by subsurface modeling conducted by in-house multidisciplinary 
teams. Furthermore, we place a strong emphasis on surveillance and conformance activities to improve current mature water injection projects. Tertiary 
recovery is being pursued with polymer and surfactant water-flooding in mature reservoirs in the Golfo de San Jorge, Cuyana and Neuquina basins. 

Continuous  technical  reviews  of  our  oil  and  gas  fields  allow  us  to  identify  opportunities  to  rejuvenate  mature  fields  and  optimize  new  field 
developments in Argentine basins in order to achieve similar recovery factors that mature fields have already reached in other regions of the world, with 
the application of new technologies. 

Staying the Path of Unconventional Resources 

In  line  with  the  production  growth  objective  driven  by  unconventional  projects,  we  continued  extending  our  leadership  in  this  area  with  the  full 
development  in  La  Amarga  Chica  block  announced  on  December  2018.  La  Amarga  Chica  has  become  the  third  project  where  YPF  and  its  partners 
successfully achieve massive development, after Loma Campana and El Orejano. Planning for a growth in production is supported by a strong portfolio 
with competitive breakeven prices. 

The international and local scenarios challenge us to adjust our efficiency and costs to be competitive. To drive down the breakeven price of our projects 
we are focused on increasing well productivity and improving operation efficiency in order to reduce development cost and operative expenses. 

During  2018,  we  reaffirmed  our  commitment  to  the  objective  of  growing  our  production  and  reserves  through  the  development  of  unconventional 
resources,  which  we  began  in  2013.  More  than  600  wells  were  drilled  with  Vaca  Muerta  shale  as  the  target,  mostly  in  the  Loma  Campana  field  in 
association  with  Chevron,  continuing  the  massive  development  that  began  in  2013.  The  remaining  wells  were  targeted  to  continue  the  development 
phase in the El Orejano block in association with Dow Chemical, the Narambuena project in association with Chevron, the La Amarga Chica pilot in 
association with Petronas, the Bandurria Sur pilot in association with SPM Argentina S.A., the Bajada de Añelo pilot in association with Shell, and the 
Rincon del Mangrullo, Aguada de la Arena and La Ribera pilots where YPF holds 100% of the working interest in those blocks. The purpose of these 
projects is to determine the potential of Vaca Muerta as a shale oil/gas reservoir. 

The  development  of  unconventional  resources  in  the  Vaca  Muerta  formation  demands  significant  capital  investment.  As  we  rapidly  progress  on  our 
learning curve, substantially improving productivity and reducing well cost by 7% in 2018 compared to 2017, we expect to continue yielding savings 
due to operational optimizations, economies of scale and increasing well productivity through a better understanding of the subsurface and the use of 
new technologies. 

In  this  context,  our  controlled  technological-based  company  of  YPF  (Y-TEC)  has  contributed  providing:  innovative  laboratory  and  operational 
techniques and protocols; better understanding of the rocks behavior; improvements in reservoir simulation and modelling tools; drilling and completion 
products; among others. See “Research and Development.” 

Nevertheless,  the  financial  viability  of  these  investments  and  resource  recovery  efforts  will  depend  on  the  prevailing  economic  and  regulatory 
conditions,  as  well  as  the  market  prices  of  hydrocarbons  in  Argentina.  See  “Item  3.  Key  Information—Risk  Factors.”  and  “Item  5.  Operating  and 
Financial Review and Prospects—Factors Affecting Our Operations” for additional information regarding 2019 activity. 

Tight sands in Rincón del Mangrullo and Aguada de la Arena also contributed to the increase of natural gas production and reserves in 2018. Six wells 
were drilled in these marine tight sands, maintaining gas production at 3.8 mmcm/d. 

Since  2016,  we  have  been  supplying  domestic  sand  as  proppant  (to  be  injected  in  the  hydraulic  stimulation  that  allows  for  the  development  of 
unconventional hydrocarbons) and finalized the sand processing plant. 

In order to guarantee the self-supply of sand for YPF and facing a scenario of increasing demand in the domestic market, we have made investments to 
improve and expand our existing productive capacities (such as the construction of a new classification and furnace for drying said product), increase 
our transportation capacity (through the extension of railway terminals) to supply the production and comply with the new product mix (as part of our 
geology research and development plan). 

39 

During 2017, we commenced testing of dissolvable plugs, chemical and mechanical diverters, frac sleeves, and different types of stimulation fluids, in 
connection with the completion of our shale gas/oil wells, seeking improved operational efficiency and well performance. We are continuing to study 
the  data  from  these  tests,  analyzing  the  results  of  productivity  in  the  medium  term.  Many  of  these  activities  were  carried  out,  and  continue  to  be 
supported by Y-TEC. 

Main properties 

Our production is concentrated in the following basins in Argentina: Neuquina, Golfo San Jorge, Cuyana, Noroeste and Austral. 

Our domestic operations are subject to certain risks. See “Item 3. Key Information—Risk Factors.” 

In 2018, 2017 and 2016, we finalized agreements related to the acquisition and development of properties that are part of our core business. In 

connection with those agreements, see Notes 3 and 29.b to the Audited Consolidated Financial Statements. 

In addition, in connection with the extension of concessions, see Note 29.a to the Audited Consolidated Financial Statements. 

The following table sets forth information regarding our developed and undeveloped acreage by geographic area as of December 31, 2018:

(1) Developed acreage is spaced or assignable to productive wells. 
(2) Undeveloped  acreage  encompasses  those  leased  acres  on  which  wells  have  not  been  drilled  or  completed  to  a  point  that  would  permit  the 

production of economic quantities of oil or gas regardless of whether such acreage contains proved reserves. 

“Net” acreage equals gross acreage after deducting third-party interests. 

(3) A “gross acre” is an acre in which we own a working interest. 
(4)
(5) Relates to Colombia, Bolivia and Chile. In the case of Colombia, YPF and its partners notified the Colombian National Hydrocarbons Agency 
(“ANH”) of the decision to relinquish the COR 12 and COR 33 blocks. In Bolivia, YPF’s net undeveloped surface acreage totaled 147,000 acres. 
Finally, in Chile, YPF’s net undeveloped surface acreage totaled 3,000 acres needed to finish the testing of one exploration well. 

Except  for  the  information  provided  in  the  next  paragraph,  as  of  December 31,  2018,  none  of  our  exploration  permits  considered  as  a  whole,  which 
include undeveloped acreage, will expire in 2019 in accordance with the Hydrocarbons Law and complementary provincial laws. In addition, according 
to Law No. 27,007 that amended  the Hydrocarbons Law, all national  offshore permits  and offshore hydrocarbon production concessions that did not 
have association agreements with ENARSA as of the date of the new law reverted and were transferred to the SGE. Permits and concessions granted 
prior  to  Law  No. 25,943  will  be  exempt  from  this  provision.  In  September  2015,  the  National  Executive  Office  and  YPF  began  negotiating  the 
conversion  of  association  agreements  signed  with  ENARSA.  On  December 29,  2017  YPF  filed  a  note  before  the  Ministry  of  Energy  confirming  its 
willingness to negotiate the conversion of association agreement related to the Area identified as “ENARSA 1”. In the same note, YPF informed that it 
communicated its decision not to convert the association agreements related such Areas to the Operators of Areas “ENARSA 2” and “ENARSA 3”. On 
October 19, 2018 YPF officially filed another note to the SGE to negotiate the conversion of the association agreement related to the area identified as 
“ENARSA 1”; as of the date of this annual report, negotiations related to this note are ongoing. YPF currently participates in three offshore blocks 

40 

in association with ENARSA, which represent approximately 55% of our net exploratory undeveloped acreage. We cannot guarantee that as a result of 
such negotiations we would not decide to relinquish to the SGE part or all of the acreage included in our current association with ENARSA. With the 
exception of the above, none of our exploration permits are regulated by Law No. 27,007. See “—Legal and Regulatory Framework and Relationship 
with the Argentine Government—Law No. 27,007 (amendment of the Hydrocarbons Law)—Exploration and Production.” 

However,  as  a  result  of  the  expiration  in  2019  of  the  first,  second  or  third  exploration  terms  of  certain  of  our  exploration  permits  (according  to  the 
original terms of the Hydrocarbons Law, which applied to our existing exploration permits), we would be required to relinquish a fixed portion of the 
acreage related to each such expiring permit, as set forth in the Hydrocarbons Law, as long as exploitable quantities of oil or gas are not discovered in 
such areas (in which case we may seek to obtain a declaration of their commercial viability from the relevant authorities, and the related areas would 
then be subject to exploitation concessions). Additionally, and depending on the circumstances that could arise in each case (for instance, the state of 
exploratory activity in a certain area), we could request an extension of the expiration of the exploration permit, which would be subject to the approval 
of the respective governing authority. As a result, if no discoveries are made in 2019, we would be required to relinquish approximately 3,542 km2 of 
exploratory  undeveloped  acreage  (approximately  8.2%  of  our  43,055  km2  of  net  exploratory  undeveloped  acreage  as  of  December 31,  2018)  during 
2019. 

Additionally, based on information available as of the date of this annual report, if we fail to make any discoveries or to engage in new activity that 
could extend the expirations of the exploration permits, we could be required or could decide to relinquish a maximum of approximately 6,126 km2 of 
exploratory undeveloped acreage (approximately 14.2% of our 43,055 km2 of net exploratory undeveloped acreage as of December 31, 2018) during 
2020 and 2021. 

According to the Hydrocarbons Law, we are entitled to decide, according to our best interest, which acreage related to each exploration permit to keep if 
we remain within the required relinquishment percentage. Therefore, the areas to be relinquished consist usually of acreage where drilling has not been 
successful and are considered non-core lease acreage. 

Except as described above, we do not have any material undeveloped acreage related to our production concessions expiring in the near term. 

See “—Legal and Regulatory Framework and Relationship with the Argentine Government—Law No. 27,007 (amendment of the Hydrocarbons Law)” 
for a description of new terms that apply to new production concessions or exploration permits, other than those already governed by previous laws. 

Argentine Exploration Permits and Exploitation Concessions 

Based  on 2017  production,  Argentina is  the  second  largest producer  of natural gas  and  the  fourth  largest producer  of crude oil in Central and South 
America, according to the 2018 edition of the BP Statistical Review of World Energy published in June 2018. Oil has historically accounted for the 
majority of the country’s hydrocarbon production and consumption, although the relative share of natural gas has increased rapidly in recent years.

(1) A  “gross  well”  is  a  well  in  which  we  own  a  working  interest.  A “net  well”  is  deemed  to  exist  when  the  sum  of  fractional  ownership working 
interests in gross wells equals one. The number of net wells is the sum of the fractional working interests owned in gross wells expressed as whole 
numbers and fractions of whole numbers 

41 

As  of  December 31,  2018,  we  held  132  exploration  permits  and  production  concessions  in  Argentina.  We  directly  operate  99  of  them,  including  20 
exploration permits and 79 production concessions. 

Exploration permits: As of December 31, 2018, we held 24 exploration permits in Argentina, 21 of which were onshore exploration permits and 3 of 
which  were  offshore  exploration  permits.  We  had  100%  ownership  of  11  onshore  permits,  and  our  participating  interests  in  the  remainder  varied 
between 50% and 70%. Our participating interests in the 3 offshore permits varied between 30% and 35%. 

Production  concessions:  As  of  December 31,  2018,  we  had  108  production  concessions  in  Argentina.  We  had  a  100%  ownership  interest  in  63 
production concessions, and our participating interests in the remaining 45 production concessions varied between 7% and 98%. 

In  addition,  we  have  36 crude  oil  treatment  plants  and  12  pumping  plants  where  oil  is  processed  and  stored.  The  purpose  of  these  plants  is  to 
receive and treat oil from different fields prior to shipment to our refineries and/or commercialization to third parties, as applicable. See “Item 3. Key 
Information—Risk Factors—Risks Relating to Our Business—Our business depends to a significant extent on our production and refining facilities and 
logistics network.” 

In connection with our principal properties, see “—Exploration & Production Activity in Argentina.” Production for each of the last three fiscal 
years by geographic area and by field containing 15% or more of our total proved reserves are set forth under “—Oil and gas production, production 
prices and production costs.” 

Approximately 92% of our proved crude oil reserves in Argentina are concentrated in the Neuquina (52%) and Golfo San Jorge (40%) basins, and 

approximately 85% of our proved gas reserves in Argentina are concentrated in the Neuquina (75%), and Austral (10%) basins. 

Joint ventures and contractual arrangements in Argentina 

As of December 31, 2018, we participated in 8 exploration and 36 production joint ventures and contractual arrangements (26 of which were not 
operated by us) in Argentina. Our interests in these joint ventures and contractual arrangements ranged from 7% to 93%, and our obligations to share 
exploration  and  development  costs  varied  under  these  agreements.  In  addition,  under  the  terms  of  some  of  these  joint  ventures,  we  have  agreed  to 
indemnify our joint venture partners in the event that our rights with respect to such areas are restricted or affected in such a way that the purpose of the 
joint venture cannot be achieved. For a list of the main exploration and production joint ventures in which we participated as of December 31, 2018, see 
Note 24 to the Audited Consolidated Financial Statements. We are also a party to a number of other contractual arrangements that arose through the 
renegotiation of service contracts and risk contracts and their conversion in exploitation concessions and exploration permits, respectively. 

Oil and Gas Reserves 

Proved  oil  and  gas  reserves  are  those  quantities  of  oil  and  gas,  which,  by  analysis  of  geoscience  and  engineering  data,  can  be  estimated  with 
reasonable  certainty  to  be  economically  producible  (from  a  given  date  forward,  from  known  reservoirs,  and  under  existing  economic  conditions, 
operating methods and government regulations) prior to the time at which contracts providing the right to operate expire, unless evidence indicates that 
renewal  is  reasonably  certain,  regardless  of  whether  deterministic  or  probabilistic  methods  are  used  for  the  estimation.  The  project  to  extract  the 
hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within reasonable time. In some cases, 
substantial investments in new wells and related facilities may be required to recover proved reserves. 

Information  on  net  proved  reserves  as  of  December 31,  2018,  2017  and  2016  was  calculated  in  accordance  with  the  SEC  rules  and  Financial 
Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 932, as amended. Accordingly, crude oil prices used to determine 
reserves were calculated each month for crude oils of different quality produced by the Company. Consequently, to calculate our net proved reserves as 
of December 31, 2018, the Company considered the realized prices for crude oil in the domestic market taking into account the effect of export taxes as 
in effect as of each of the corresponding years (until 2020, in accordance with Decree No. 793/2018). For the years beyond the mentioned periods, the 
Company considered the unweighted average price of the first-day-of-the-month for each month within the twelve-month period ended December 31, 
2018, which refers to the Brent prices adjusted by each different quality produced by the Company. 

42 

Additionally, since there are no benchmark market natural gas prices available in Argentina, the Company considered the realized prices in the 
domestic market according to the SEC and FASB’s ASC 932 rules, but also taking into account the effect of certain market regulations which were put 
in place mainly during the second half of 2018. 

Notwithstanding  the  foregoing,  commodity  prices  have  changed  significantly  since  2016.  See  “Item  3. Key  Information—Risk  Factors—Risks 
Relating  to  Our  Business—Our  oil  and  natural  gas  reserves  are  estimates”  and  “Item  3.  Key  Information—Risk  Factors—Risks  Relating  to  Our 
Business—Our reserves and production are likely to decline.” 

Net reserves are defined as that portion of the gross reserves attributable to the interest of YPF after deducting interests owned by third parties. In 
determining net reserves, the Company excludes from its reported reserves royalties due to others, whether payable in cash or in kind, where the royalty 
owner has a direct interest in the underlying production and is able to make lifting and sales arrangements independently. By contrast, to the extent that 
royalty payments required to be made to a third party, whether payable in cash or in kind, are a financial obligation, or are substantially equivalent to a 
production  or  severance  tax,  the  related  reserves  are  not  excluded  from  the  reported  reserves  despite  the  fact  that  such  payments  are  referred  to  as 
“royalties” under local rules. The same methodology is followed in reporting our production amounts. 

Gas  reserves  exclude  the  gaseous equivalent  of  liquids  expected  to  be  removed  from  the  gas  on  concessions  and  leases,  at  field  facilities  and  at  gas 
processing plants. These liquids are included in net proved reserves of NGLs. 

Technology used in establishing proved reserves additions 

YPF’s estimated proved reserves as of December 31, 2018 are based on estimates generated through the integration of available and appropriate 
data,  utilizing  well-established  technologies  that  have  been  demonstrated  in  the  field  to  yield  repeatable  and  consistent  results.  Data  used  in  these 
integrated assessments include information obtained directly from the subsurface via wellbore, such as well logs, reservoir core samples, fluid samples, 
static and dynamic pressure information, production test data, and surveillance and performance information. The data utilized also include subsurface 
information obtained through  indirect measurements, including high  quality  2-D  and  3-D  seismic  data,  calibrated with available well  control.  Where 
applicable,  geological  outcrop  information  was  also  utilized.  The  tools  used  to  interpret  and  integrate  all  this  data  included  both  proprietary  and 
commercial  software  for  reservoir  modeling,  simulation  and  data  analysis.  In  some  circumstances,  where  appropriate  analog  reservoir  models  are 
available, reservoir parameters from these analog models were used to increase the reliability of our reserves estimates. 

For further information on the estimation process of our proved reserves, see “—Internal controls on reserves and reserves audits.”

For information regarding changes in our estimated proved reserves during 2018, 2017 and 2016, see Note 35 to the Audited Consolidated Financial 
Statements. 

The paragraphs below explain in further detail the most significant changes in our proved undeveloped reserves during 2018, 2017 and 2016. 

Changes in our proved undeveloped reserves during 2018 

YPF had estimated a volume of net proved undeveloped reserves of 358 mmboe at December 31, 2018, which represented approximately 33% of 
the  1080  mmboe  total  reported  proved  reserves  as  of  such  date.  This  compares  to  estimated  net  proved  undeveloped  reserves  of  266  mmboe  as  of 
December 31, 2017 (approximately 29% of the 929 mmboe total reported proved reserves as of such date). 

The 35% total net increase in net proved undeveloped reserves in 2018 is mainly attributable to: 

•

•

•

Extensions and discoveries, which added 149 mmboe (238 bcf of Gas and 107 mmbbl of Oil) of proved undeveloped reserves mainly from 
shale oil and gas projects from Vaca Muerta formation at Neuquina basin. 

New  economic  conditions  with  higher  gas  and  oil  average  prices  and  lower  operating  costs  which  resulted  in  a  48  mmboe  Proved 
Undeveloped Reserves  incorporation  mainly  from oil  and  gas  fields  of Neuquina basin  (15  mmboe) and  oil  fields  from  Golfo  San  Jorge 
basin (33 mmboe). 

New  improved  recovery  projects,  adding  approximately  9  mmboe  of  proved  undeveloped  secondary  recovery  reserves.  Most  important 
additions belong to Golfo San Jorge and Neuquina basins. 

This was partially offset by: 

•

•

•

•

Ongoing successful development activities related to proved undeveloped reserves projects, which allowed a transfer of approximately 67 
mmboe to proved developed reserves. The main contributions are related to Development Wells (58 mmboe) mainly in Neuquina basin and 
improved recovery projects (9 mmboe) mainly in Golfo San Jorge and Neuquina basins. 

Change of development strategy in certain areas which resulted in a downwards revision of 43 mmboe from previous projects, mainly from 
Neuquina, Austral and Golfo San Jorge basins. 

Some  primary  and  improved  recovery  oil  projects  development  schedules  were  modified  or  canceled,  resulting  in  a  5  mmboe  proved 
undeveloped reserves reduction, mainly in Austral, Golfo San Jorge and Cuyana basins. 

Changes in gas compression projects which resulted in a 5 mmboe reduction of proved undeveloped reserves, mainly from Neuquina basin. 

YPF’s  total  capital  expenditures  to  continue  the  development  of  reserves  was  approximately  U.S.$  936 million  during  2018,  of  which  U.S.$ 

655 million was allocated to projects related to proved undeveloped reserves. 

As of December 31, 2018, we did not have material amounts of proved undeveloped reserves in individual fields or countries that have remained 

undeveloped for five years or more after being disclosed as proved undeveloped reserves. 

Changes in our proved undeveloped reserves during 2017 

YPF had estimated a volume of net proved undeveloped reserves of 266 mmboe at December 31, 2017, which represented approximately 29% of 
the  929  mmboe  total  reported  proved  reserves  as  of  such  date.  This  compares  to  estimated  net  proved  undeveloped  reserves  of  298  mmboe  as  of 
December 31, 2016 (approximately 27% of the 1,113 mmboe total reported proved reserves as of such date). 

The 11% total net decrease in net proved undeveloped reserves in 2017 is mainly attributable to: 

•

•

•

Ongoing  successful  development  activities  related  to  proved  undeveloped  reserves  projects,  which  allowed  a  transfer  of 
approximately 82 mmboe to proved developed reserves. Main contributions are related to development wells (62 mmboe) mainly in 
Neuquina basin, improved recovery projects (9,5 mmboe) mainly in Golfo San Jorge and Neuquina basins, and Gas Compression 
Projects (9,5 mmboe) in Austral and Neuquina basins. 

New economic conditions with lower gas and oil average prices and higher operating costs affected scheduled projects economics, 
resulting in a 20 mmboe proved undeveloped reserves reduction mainly from oil fields of Neuquina basin (-16 mmboe) and Golfo 
San Jorge basin (-3 mmboe). 

Some primary and improved recovery oil projects development schedule was modified or canceled, resulting in a 2,5 mmboe proved 
undeveloped reserves reduction, mainly in Neuquina and Golfo San Jorge basins. 

45 

This was partially offset by: 

•

•

•

•

Extensions and discoveries, which added 54 mmboe (219 bcf of Gas and 12 mmbbl of Oil) of proved undeveloped reserves mainly 
from Neuquina and Austral basins. 

New  improved  recovery  projects,  adding  approximately  21  mmboe  of  proved  undeveloped  secondary  recovery  reserves.  Most 
important additions belong to Golfo San Jorge and Neuquina basins. 

New project studies in Golfo San Jorge and Neuquina basins added approximately 5 mmboe of proved undeveloped reserves. 

The extension of Rincón del Mangrullo and Magallanes fields’ concessions resulted in approximately 4 mmboe reserves addition in 
proved undeveloped reserves. 

YPF’s  total  capital  expenditure  to  continue  the  development  of  reserves  was  approximately  U.S.$1,113 million  during  2017,  of  which  U.S.$ 

693 million was allocated to projects related to proved undeveloped reserves. 

As of December 31, 2017, we did not have material amounts of proved undeveloped reserves in individual fields or countries that have remained 

undeveloped for five years or more after being disclosed as proved undeveloped reserves. 

Changes in our proved undeveloped reserves during 2016 

YPF had estimated a volume of net proved undeveloped reserves of 298 mmboe at December 31, 2016, which represented approximately 27% of 
the  1,113  mmboe  total  reported  proved  reserves  as  of  such  date.  This  compares  to  estimated  net  proved  undeveloped  reserves  of  337  mmboe  as  of 
December 31, 2015 (approximately 27% of the 1,226 mmboe total reported proved reserves as of such date). 

The approximately 11% net decrease in net proved undeveloped reserves in 2016 is mainly attributable to: 

•

•

•

Ongoing  successful  development  activities  related  to  proved  undeveloped  reserves  projects,  which  allowed  a  transfer  of 
approximately 116 mmboe to proved developed reserves. Main contributions are related to development wells (75 mmboe), mainly 
in  the  Neuquina  basin,  improved  recovery  projects  (14  mmboe),  mainly  in  the  Golfo  San  Jorge  and  Neuquina  basins,  and  gas 
compression projects in the Neuquina basin (12 mmboe). 

New economic conditions with lower average oil prices that affected the economics of scheduled projects, resulting in a reduction of 
proved  undeveloped  reserves  of  45  mmboe,  mainly  from  the  oil  fields  of  the  Golfo  San  Jorge  basin  (-16  mmboe),  the  Neuquina 
basin (-14 mmboe) and the Austral basin (-12 mmboe). 

In the Golfo San Jorge basin, the development schedules of several primary and improved recovery oil projects were modified or 
canceled, resulting in a reduction of proved undeveloped reserves of 20 mmboe. 

This was partially offset by: 

•

•

•

Extensions and discoveries, which added 80 mmboe (242 bcf of gas and 29 mmbbl of oil) of proved undeveloped reserves, mainly 
from the Neuquina basin. 

New project studies, which added approximately 12 mmboe of proved undeveloped reserves, mainly from the Neuquina basin. 

New improved recovery projects, adding approximately 30 mmboe of proved undeveloped secondary recovery reserves. The most 
important additions belong to the Golfo San Jorge and Neuquina basins. 

The acquisition of interests in the Rio Neuquén gas field located in the Neuquina basin resulted in the addition of approximately 11 mmboe of 

proved undeveloped reserves. 

YPF’s  total  capital  expenditure  to  continue  the  development  of  reserves  was  approximately  U.S.$  2,930 million  during  2016,  of  which  U.S.$ 

1,214 million was allocated to projects related to proved undeveloped reserves. 

As of December 31, 2016, we did not have material amounts of proved undeveloped reserves in individual fields or countries that have remained 

undeveloped for five years or more after being disclosed as proved undeveloped reserves. 

Internal controls on reserves and reserves audits 

All of our oil and gas reserves held in consolidated companies have been estimated by our petroleum engineers. In order to meet the high standard 
of  “reasonable  certainty,”  reserves  estimates  are  stated  taking  into  consideration  additional  guidance  as  to  reservoir  economic  producibility 
requirements,  acceptable  proved  area  extensions,  drive  mechanisms  and  improved  recovery  methods,  marketability  under  existing  economic  and 
operating conditions and project maturity. 

46 

Where applicable, the volumetric method is used to determine the original quantities of petroleum in place. Estimates are made by using various 
types  of  logs,  core  analysis  and  other  available  data.  Formation  tops,  gross  thickness  and  representative  values  for  net  pay  thickness,  porosity  and 
interstitial fluid saturations are used to prepare structural maps to delineate each reservoir and isopachous maps to determine reservoir volume. Where 
adequate  data  is  available  and  where  circumstances  are  justified,  material-balance  and  other  engineering  methods  are  used  to  estimate  the  original 
hydrocarbon in place. 

Estimates of ultimate recovery are obtained by applying recovery factors to the original quantities of petroleum in place. These factors are based 
on the drive mechanisms inherent in the reservoir, analysis of the fluid and rock properties, the structural position of the reservoir and its production 
history. In some instances, comparisons are made with similar production reservoirs in the areas where more complete data is available. 

Where  adequate  data  is  available  and  where  circumstances  are  justified,  material-balance  and  other  engineering  methods  are  used  to  estimate 
ultimate recovery. In  these instances, reservoir  performance parameters  such as  cumulative  production,  production rate,  reservoir  pressure, gas  to oil 
ratio behavior and water production are considered in estimating ultimate recovery. 

In certain cases where the above methods could not be used, proved reserves are estimated by analogy to similar reservoirs where more complete 

data are available. 

To control the quality of reserves booking, a process has been established that is integrated into the internal control system of YPF. 

This process to manage reserves booking is centrally controlled and has the following components: 

(a)

(b)

The Reserves Audit (“RA”) is separate and independent from the Upstream segment. RA’s activity is overseen by YPF’s Audit Committee, which 
is  also  responsible  for  supervising  the  procedures  and  systems  used  in  the  recording  of  and  internal  control  over  the  Company’s  hydrocarbon 
reserves. The primary objectives of the RA are to ensure that YPF’s proved reserves estimates and disclosure are in compliance with the rules of 
the SEC, the FASB, and the Sarbanes-Oxley Act, and to review annual changes in reserves estimates and the reporting of YPF’s proved reserves. 
The RA is responsible for preparing the information to be publicly disclosed concerning YPF’s reported proved reserves of crude oil, NGLs, and 
natural gas. In addition, the RA is also responsible for providing training to personnel involved in the estimation of reserves and reporting process 
within  YPF.  The  RA  is  managed  by  and  staffed  with  individuals  that  have  an  average  of  more  than  20  years  of  technical  experience  in  the 
petroleum  industry,  including  in  the  classification  and  categorization  of  reserves  under  the  SEC  guidelines.  The  RA  staff  includes  several 
individuals who hold advanced degrees in either engineering or geology, as well as individuals who hold bachelor’s degrees in various technical 
studies. Several members of the RA are registered with or affiliated to the relevant professional bodies in their fields of expertise. 

The  Reserves  Auditor,  who  has  headed  the  RA  since  June  2017,  is  responsible  for  overseeing  the  preparation  of  the  reserves  estimates  and 
reserves  audits  conducted  by  third  party  engineers.  The  current  Reserves  Auditor  has  over  35  years  of  experience  in  geology  and  geophysics, 
reserves estimate, project development, finance and general accounting regulations. Prior to becoming the Reserves Auditor, he was the general 
manager in E&D, and before that he worked as the Director for Exploration at YPF. He holds a degree in geology from the National University of 
Patagonia, and postgraduate courses at IAE Austral University. Consistent with our internal control system requirements, the Reserves Auditor’s 
compensation is not affected by changes in reported reserves. 

(c) A quarterly internal review by the RA of changes in proved reserves submitted by the Upstream business segment and associated with properties 

where technical, operational or commercial issues have arisen. 

(d) A Quality Reserve Coordinator (“QRC”) is assigned to each Upstream business segment of YPF to ensure that there are effective controls in the 
estimation  of  proved  reserves  and  approval  process  of  the  estimates  of  YPF  and  the  timely  reporting  of  the  related  financial  impact  of  proved 
reserves changes. Our QRCs are responsible for reviewing proved reserves estimates. The qualification of each QRC is made on a case-by-case 
basis  with  reference  to  the  recognition  and  respect  of  such  QRC’s  peers.  YPF  would  normally  consider  a  QRC  to  be  qualified  if  such  person 
(i) has a minimum of 5 years of practical experience in petroleum engineering or petroleum production geology, with at least three years of such 
experience  in  charge  of  the  estimation  and  evaluation  of  reserves,  and  (ii) has  either  (A) obtained,  from  a  college  or  university  of  recognized 
stature,  a  bachelor’s  or  advanced  degree  in  petroleum  engineering,  geology  or  other  related  discipline  of  engineering  or  physical  science,  or 
(B) received, and is maintaining in good standing, a registered or certified professional engineer’s license or a registered or certified professional 
geologist’s license, or the equivalent thereof, from an appropriate governmental authority or professional organization. 

(e) A formal review through technical review committees to ensure that both technical and commercial criteria are met prior to the commitment of 

capital to projects. 

47 

(f)

Our  internal  audit  team  examines  the  effectiveness  of  YPF’s  financial  controls,  which  are  designed  to  ensure  the  reliability  of  reporting  and 
safeguarding of all the assets and examines YPF’s compliance with the law, regulations and internal standards. 

(g) All volumes booked are submitted to a third party reserves audit on a periodic basis. The properties selected for a third party reserves audit in any 

given year are selected on the following basis: 

i.

ii.

all properties on a three-year cycle; and 

recently acquired properties not submitted to a third party reserves audit in the previous cycle and properties with respect to which there is 
new information which could materially affect prior reserves estimates. 

For  those  areas  submitted  to  a  third  party  reserves  audit,  YPF’s  proved  reserves  figures have  to  be  within  7%  or  10  mmboe  of  the  third  party 
reserves audit figures for YPF to declare that the volumes have been ratified by a third party reserves audit. In the event that the difference is greater 
than the tolerance, YPF will re-estimate its proved reserves to achieve this tolerance level or should disclose the third party figures. YPF has adopted the 
above-mentioned procedure by approving the corresponding internal policy. 

In 2018, Gaffney, Cline & Associates audited certain YPF operated and non-operated areas in the Neuquina, Golfo San Jorge, Austral and Cuyana 
basins  of  Argentina.  These  audits  were  performed  as  of  December 31,  2018,  and  the  audited  fields  contain  in  aggregate,  according  to  our  estimates, 
approximately 365 mmboe proved reserves (161 mmboe of which were proved undeveloped reserves) as of such date, which represented approximately 
34% of our proved reserves and 45% of our proved undeveloped reserves as of December 31, 2018. Copies of the related reserves audit reports are filed 
as an exhibit to this annual report. 

We are required, in accordance with Resolutions No. 324/06 and 69/16 of the Argentine Secretariat of Hydrocarbon Resources, to annually file by 
March 31 details of our estimates of our oil and gas reserves and resources with the Argentine Secretariat of Hydrocarbon Resources, as defined in that 
resolution and certified by an external auditor. The aforementioned certification and external audit only have the meaning established by Resolutions 
No. 324/06 and 69/16 and are not to be interpreted as a certification or external audit of oil and gas reserves under SEC rules. We last filed such a report 
for  the  year  ended  December 31,  2017.  Estimates  of  our  oil  and  gas  reserves  filed  with  the  Argentine  Secretariat  of  Hydrocarbon  Resources  are 
materially higher than  the  estimates  of our  proved  oil  and  gas  reserves  contained  in this  annual report mainly  because:  (i) information  filed  with  the 
Argentine Secretariat of Hydrocarbon Resources includes all properties of which we are operators, irrespective of the level of our ownership interests in 
such properties; (ii) information filed with the Argentine Secretariat of Hydrocarbon Resources includes other categories of reserves and resources that 
are not included in this annual report, which are different from estimates of proved reserves consistent with the SEC’s guidance contained in this annual 
report;  and  (iii) the  definition  of  proved  reserves  under  Resolutions  No. 324/06  and  69/16  is  different  from  the  definition  of  “proved  oil  and  gas 
reserves” established in Rule 4-10(a) of Regulation S-X. Accordingly, all proved oil and gas reserve estimates included in this annual report reflect only 
proved oil and gas reserves consistent with the rules and disclosure requirements of the SEC. 

Oil and gas production, production prices and production costs 

The following table shows our crude oil (including oil and condensate), NGL, and gas production on an as sold and annual basis for the years 
indicated. In determining net production, we exclude royalties due to others, whether payable in cash or in kind, where the royalty owner has a direct 
interest in such production and is able to make lifting and sales arrangements independently. By contrast, to the extent that royalty payments required to 
be made to a third party, whether payable in cash or in kind, are a financial obligation or are substantially equivalent to a production or severance tax, 
they are not excluded from our net production amounts despite the fact that such payments are referred to as “royalties” under local rules. This is the 
case for our production in Argentina, where royalty expense is accounted for as a production cost.

Not material (less than 1). 
Loma La Lata Central and Loma La Lata Norte (southern and northern parts of the Loma La Lata field) in Argentina contain approximately 17% 
of our total proved reserves expressed on an oil equivalent barrel basis. Oil and condensate production in these fields was approximately 8, 6 and 
6  mmbbl  for  the  years  ended  December 31,  2018,  2017  and  2016,  respectively.  NGL  production  in  these  fields  was  approximately  5,  8  and  8 
mmbbl for the years ended December 31, 2018, 2017 and 2016, respectively. Natural gas production in the Loma La Lata field was 109, 127 and 
132 bcf for the years ended December 31, 2018, 2017 and 2016, respectively. 

(2) Crude  oil  production  for  the  years  ended  in  December 31,  2018,  2017  and  2016  includes  an  estimated  12,  12  and  13  mmbbl,  respectively,  in 
respect  of  royalty  payments  which  are  a  financial  obligation  or  are  substantially  equivalent  to  a  production  or  similar  tax.  Equity-accounted 
entities production of crude oil in respect of royalty payments which are a financial obligation or are substantially equivalent to a production or 
similar tax is not material. 

(3) NGL production for the years ended in December 31, 2018, 2017 and 2016 includes an estimated 2, 2 and 2 mmbbl, respectively, in respect of 
royalty  payments  which  are  a  financial  obligation  or  are  substantially  equivalent  to  a  production  or  similar  tax.  Equity-accounted  entities 
production of NGL in respect of royalty payments which are a financial obligation or are substantially equivalent to a production or similar tax is 
not material. 

(4) Natural  gas  production  for  the  years  December 31,  2018,  2017  and  2016  includes  an  estimated  61,  64  and  60  bcf,  respectively,  in  respect  of 
royalty  payments  which  are  a  financial  obligation  or  are  substantially  equivalent  to  a  production  or  similar  tax.  Equity-accounted  entities 
production of natural gas in respect of royalty payments which are a financial obligation or are substantially equivalent to a production or similar 
tax is not material. 

(5) Does  not  include  volumes  consumed  or  flared  in  operations  (whereas  sale  volumes  shown  in  the  reserves  table  included  in  “Supplemental 

Information on Oil and Gas Exploration and Production Activities—Oil and Gas Reserves” include volumes consumed in operations). 

(6) Volumes of natural gas have been converted to barrels of oil equivalent at 5,615 cubic feet per barrel. 

The composition of the crude oil produced by us in Argentina varies by geographic area. Almost all crude oil produced by us in Argentina has 
very low or no sulfur content. We sell substantially all the crude oil we produce in Argentina to our Refining and Marketing business segment. Most of 
the natural gas produced by us is of pipeline quality. All of our gas fields produce commercial quantities of condensate, and substantially all of our oil 
fields produce associated gas.

Exploration & Production Activity in Argentina 

During 2018, our main exploratory and development activities in Argentina have had the following principal focus: 

1. Operated Areas—Exploratory Activities 

During 2018, our exploratory activities in Argentina were mainly focused on: 

1.1 Onshore 

Unconventional activities 

We continued the regional exploration of shale oil and gas to determine its productivity in different areas of the Neuquina Basin. During 2018, 
five wells targeting Vaca Muerta Formation (Fm), one well to Agrio Fm and one workover to Los Molles Fm. have been drilled. The workover was 
positive  and  as  of  the  date  of  the  annual  report,  three  Vaca  Muerta  wells  and  one  Agrio  well  are  pending  completion  and  the  other  two  wells  are 
currently being drilled. 

52 

Continuing  the  exploration  of  different  source  rocks,  two  workovers  were  done  to  evaluate  the  potential  of  the  shale  oil  and  gas  in  Tierra  del 

Fuego Province. The result of the first one was below expectation and the second workover is still ongoing. 

Tight gas: Exploration of tight gas continued during 2018 in Estación Fernández Oro, Loma La Lata-Sierra Barrosa and Los Caldenes Blocks. 

Positive results were obtained in three wells and the other two are pending completion. 

Conventional activities 

• Neuquina Basin: 

•

•

•

•

•

A  total  of  seven  wells  targeting  conventional  oil  and  gas  reservoirs  were  drilled  in  the  basin,  obtaining  two  positive  results  in 
Chachahuén Block and one in Valle del Río Grande (all of them oil wells). 

Results in two other wells were below expectations (Los Caldenes Block and Malargüe). As of the date of this annual report, two 
others are pending completion. 

From  the  results  obtained  in  Chachahuén,  we  have  notified  the  Mendoza  Province  of  our  decision  to  convert  the  Chachahuén 
Exploration Permit into an Evaluation Area and to extend the permit until February 2020. We are still waiting for the final approval 
from the province. 

Having  fulfilled  all  commitments  in  Payún  Oeste  Block,  in  2017  we  requested  that  the  Mendoza  province  allow  commercial 
exploitation of the area. However, in 2018, considering all results obtained, we decided not to continue with the exploratory periods. 
Consequently, we sent a new note to the Mendoza Province informing of our decision to relinquish the block. 

During 2018, five new exploration blocks have been awarded in this basin: 

• Mendoza Province: Puesto Pozo Cercado Occidental, CN III Norte, CN VII/A and Los Parlamentos. 

•

Río Negro Province: Cerro Manrique 

• Golfo San Jorge basin 

•

During 2018, eight exploration wells were drilled in the Golfo San Jorge basin. The exploration activity targeted conventional oil 
and gas and tight gas reservoirs with negative results in two tight gas wells in Los Perales Block (gas) and positive results in one 
conventional well in El Trébol-Escalante Block. There are five wells pending completion. 

• Cuyana basin 

•

•

3 wells targeting conventional oil were drilled in Mesa Verde Block, two showing positive results and one below expectation. 

Having  fulfilled  all  commitments  in  CCyB  17/B  and  considering  the  obtained  results,  we  decided  not  to  continue  with  the 
exploratory periods and, as a result, the block was relinquished to the Mendoza Province. As of the date of this annual report, we are 
still awaiting response from the province. 

• Austral basin 

•

Drilling activities took place in Tierra del Fuego Province: 

•

•

•

Positive results were obtained in one oil well drilled in Tierra del Fuego “Fracción E” Block. 

Negative results came from one well drilled in Los Chorrillos Block (conventional oil). 

Two oils and one gas wells are pending completion as of the date of this annual report. 

53 

•

During 2018, one new exploration block has been awarded in Tierra del Fuego: CA-12 Bloque I. 

• Seismic 

During 2018, seismic 3D data covering 450 km2 was recorded in Cerro Manrique Block and 580 km of 2D seismic was registered in Chelforó 

(both in Río Negro Province, Neuquina basin). 

After performing the survey, seismic data processing will be carried out for subsequent interpretation. The purpose of recording and processing 

the seismic data is to fulfil commitments and to identify new exploration opportunities. 

1.2 Offshore:

According  to  the  amendments  to  the  Hydrocarbons  Law  adopted  by  Law  No. 27,007,  all  exploration  permits  owned  by  ENARSA  will  be 
transferred to the Secretariat of Energy. YPF currently participates in three offshore blocks in association with ENARSA (E1 block: YPF 35%, E2 
block: YPF 33% and E3 block: YPF 30%) with total acreage of 23,700 km2. In September 2015, the National Executive Office and YPF began 
negotiating  the  conversion  of  association  agreements  signed  with  ENARSA.  On  December 29,  2017  YPF  filed  a  note  before  the  Ministry  of 
Energy confirming its willingness to negotiate the conversion of association agreement related to the Area identified as “ENARSA 1”. In the same 
note,  YPF  informed  that  it  communicated  its  decision  not  to  convert  the  association  agreements  related  such  Areas  to  the  Operators  of  Areas 
“ENARSA 2” and “ENARSA 3”. On October 19, 2018 YPF officially filed another note to the SGE to negotiate the conversion of the association 
agreement related to the area identified as “ENARSA 1”; as of the date of this annual report, negotiations related to this note are ongoing. As of 
December 31,  2018,  we  do  not  have  registered  assets  in  these  blocks.  See  “—Legal  and  Regulatory  Framework  and  Relationship  with  the 
Argentine Government—Law No. 27,007 (amendment of the Hydrocarbons Law)” for a description of new terms which apply to new production 
concessions or exploitation permits. 

Non-Operated Areas—Exploratory Activities 

During 2018, one workover and nine exploration wells have been drilled in non-operated blocks: 

CNQ-7 and CNQ-7A: a total of six conventional oil wells were drilled by Pluspetrol: three with positive results, two below expectations and one 
is still pending completion. 

Agua Salada: two wells were drilled by Tecpetrol with positive results. 

Aguaragüe: one gas well targeting the Noa Paleozoica Formation was drilled by Tecpetrol with negative results. 

Aguada Pichana Este: one exploratory workover was done by Total showing negative results. 

Development Activities 

During  2018,  our  development  activities  in  Argentina  were  mainly  focused,  according  to  the  organizational  structure  in  force  in  2018,  on  the 
following regions and blocks: 

Unconventional Region 

During 2018, Unconventional Regional production was 98.6 mboe/d, representing 18.6% of YPF’s total production.

Loma Campana Area:

On  July 16,  2013,  YPF  and  Chevron  signed  an  investment  project  agreement  for  the  joint  exploitation  of  unconventional  hydrocarbons  in  Neuquén 
Province. 

During 2018, 37 horizontal wells were put into production, achieving a performance that, on average, met the expectations set by the Type Well for the 
Organico target and above expectations for the Cocina target (the deeper productive interval within Vaca Muerta formation). The well design ranges, 
from 1,500 m of lateral length and 18 frac stages to 3,200 m of lateral length and 40 frac stages (while the space between frac stages was maintained at 
80 m). 

The current development strategy consists of drilling Cocina and Organico targets in order to maximize drainage area (Cocina target had been set aside 
until 2017). Also, the first infill well to the Cocina was put on production with promising early performance, opening an opportunity to develop this 
target in areas where only wells to the Organico (productive interval within Vaca Muerta formation) were drilled. A longer lateral well of 3,200 m of 
lateral length was successfully completed (40 stages) and put into production in August 2018. 

Geosteering has been included as a standard in order to determine the incremental productivity gain from navigating within a desired target zone. 

Due to continued improvements in our drilling performance, drilling time was reduced by 26% between 2015 and 2018. An average drilling time of 35 
days to drill a 4,700 m measured depth (“MD”) well was achieved during 2015, with an improvement to 29 days for a 4,800 m MD in 2016 and an 
improvement to 22 days for a 5,000 m MD in 2017 and further improvement to 26 days for a 5,500 m MD in 2018. This reduction in drilling time is also 
reflected in drilling costs of an average well cost reduction of 2% between 2017 and 2018 for horizontals wells and a reduction in development cost of 
15% during the same period. 

In 2018 various pilots were executed in an effort to reduce our development cost through economically improving EUR (Estimated Ultimate Recovery) 
or reducing well cost with a minimal or negligible impact to well EUR. The executed key pilots to achieve this objective were: 

High Density Completion: a two well pilot was executed on a single location to understand the impact on well productivity and well cost of reducing 
distance between frac stages to 60m (increasing number of stages per well), reaching 10 clusters per stage and the injection of 100% of Slick Water 
(SW). 

Well Spacing: A three well pilot was executed to understand the impact on well productivity and interference by increasing well spacing from 300m to 
400m within the same target and 200m between different targets. 

Cocina Infill: As mentioned above, a Cocina well between depleted Organico wells was completed and put into production with results according to the 
expected curve of the well type. The success of this type of strategy could lead to an increase in drilling and completion activity of more than 50 wells in 
the field. 

Activity in this area in 2018 involved a gross investment of U.S.$ 376 million in drilling and completion (D&C) and U.S.$ 39 million in production 
facilities. 

La Amarga Chica Area:

On December 10, 2014, YPF and PETRONAS E&P ARGENTINA S.A., an affiliate of PETRONAS E&P Overseas Ventures Sdn. Bhd (“PEPOV”) of 
Malaysia, executed a Project Investment Agreement (the “Investment Agreement”) aiming to perform joint exploitation of unconventional hydrocarbons 
in the La Amarga Chica area in the Neuquén province. YPF will be the operator of the area. 

The Pilot Plan, comprising 30 wells in three years, started in May 2015. At the end of the first phase, a total of six horizontal and three vertical wells 
were  drilled,  with  results  over  performing  previous  expectations.  Based  on  those  positive  results,  PETRONAS  E&P  ARGENTINA  S.A.  agreed  to 
continue co-investing in a second phase of the pilot project. By the end of 2016, four additional horizontal wells from this phase were drilled, reaching a 
total of nine drilled wells during 2016, with a drilling rig fully dedicated to the project. During 2017, 12 horizontal wells were drilled, completing phase 
2 of the project and paving the way for the final phase of the project. Six of those wells were put into production with the expected performance. All of 
the drilled horizontal drains were standardized at 1,500m long except for two wells that reached 2,000m. An improvement in performance of drilling 
(time and cost) is still observed, with drilling time and well cost being reduced by 22% and 11%, respectively, between 2017 and 2018. This drilling and 
completion activity developed during 2018 comprised a total gross investment of U.S.$ 138 million, with an additional U.S.$ 38 million expended on 
production facilities. 

56 

During the pilot phase, the lateral length of the wells was increased to 2,500m in PAD33 and a new landing zone was drilled (LZ 2.5). A pilot of High 
Density Completion was executed in PAD30, increasing the number of fracture stages in two wells (spacing between stages was reduce to 60m), and 
larger fluid volumes (2,000cm per stage). The LACh-49 well drilled in a zone considered as low maturity, performed above expectations, opening new 
drilling  prospects  in  this  sector  of  the  field.  An  intensive  data  acquisition  plan  that  considers  Pressure,  Volume,  Temperature  (“PVT”),  Diagnostic 
Fracture Injection Testing (“DFITs”), static gradients and fluid samples for geochemistry studies is ongoing. The first water disposal well was put into 
operation as part of the water management plan for the field. 

At the beginning of 2018, YPF and PETRONAS E&P ARGENTINA S.A., an affiliate of PETRONAS E&P Overseas Ventures Sdn. Bhd (“PEPOV”) of 
Malaysia, ratified their intention to continue with the pilot in the area. During 2018, the pilot phase of the LACh project was completed (7 wells were 
drilled, initial results behave according to expectations) and the third phase was initiated, where both companies considered the drilling of 10 horizontal 
wells and the construction of new facilities and installations in order to transport the shale oil production derived from the area. 

By December 2018, the development phase of the Shale Oil Field started, reaching a production curve higher than expected. 

By the end of 2018, the total oil production increased to 1,599 cm/d (135% higher than December 2017) with a total of 35 wells in production. 

In 2019, a pilot test of five wells will evaluate five different landing zones and well spacing and stimulation design. 

Bandurria Sur Area: 

On July 5, 2017, YPF and SPM Argentina S.A. executed an agreement defining the main terms and conditions for the joint development of a shale oil 
pilot in two phases. YPF will be the operator of the area. 

Prior to the agreement, between 2012 and early 2016, YPF drilled and completed three vertical and two horizontal wells. 

Three  additional  horizontal  wells  were  drilled  during  2017  in  the  South  East  (“SE”)  area  of  the  block.  The  objective  of  these  wells  was  to  test 
productivity  in  different  landing  zones  within  the  Vaca  Muerta  organic-rich  section.  Two  of  the  wells  were  completed  with  performance  exceeding 
expectations. 

During  2018,  YPF  and  SPM  drilled  one  vertical  well,  one  vertical  plus  side  track,  and  six  horizontal  wells  distributed  in  three  pads  located  in  the 
northwest, center and southeast of the block. The objective of the vertical well/section was data acquisition (core and full suite of logs) for reservoir 
characterization. The objective of the horizontal wells was to test Vaca Muerta productivity across different fluid windows in different landing zones. 
The horizontal wells have between 1,500m and 2,000m of lateral length and between 20 and 38 frac stages. 

On  July 18,  2018,  by  means  of  Decree  No. 1,020/18,  the  National  Executive  Office  of  the  Province  of  Neuquén,  authorized  the  assignment  of 
participation foreseen in the definitive agreements. 

All horizontal wells were recently connected for production. Initial results are in line with the estimated type curve. 

On  October 10,  2018,  we  had  a  major  spill  in  the  area  of  Bandurria  Sur  caused  by  a  blowout  (decontrol  of  well).  For  this  reason,  the  provincial 
government  decided  to  revoke the  environmental  licences  for  the pad  8  and  9  (this  last  one  containing  the  uncontrolled  well).  As  of the date  of  this 
annual  report  the  pad  8  has  already  normalized  and  continues  the  scheduled  perforation  activities  and  with  respect  to  the  pad  9  we  continue  the 
remediations activities. 

The plan for 2019 is to start factory mode development in the southeast corner of the block while derisking of the center and western areas continues.

Bajo del Toro Area: 

Between 2012 and 2015, YPF and its partners (EOG Resources Inc, successor to Enron Oil & Gas Company, and Gas y Petróleo de Neuquén) drilled 
one slanted and two vertical exploratory wells. One of the vertical wells and the slanted well were completed (with 6 and 8 frac stages respectively) and 
proved oil production from the whole organic-rich section of the Vaca Muerta Formation. The other vertical well was used for reservoir characterization 
and  for  microseismic  monitoring  of  the  slanted  well.  Between  2016  and  2017  the  joint  venture  was  dissolved,  and  part  of  the  block  reverted  to  the 
province. 

On January 17, 2018, YPF, Bajo del Toro I S.R.L. and Statoil Argentina B.V- Sucursal Argentina entered into an agreement defining the main terms and 
conditions for the joint development of a shale oil pilot in Bajo del Toro block, being YPF as the operator of the area. 

During 2018, the joint venture continued with the characterization and evaluation of Vaca Muerta initiated in 2012, placing a pad in the southwestern 
area of the block. The pad included one vertical pilot section plus a side-track horizontal drain and one horizontal well. The objective of the horizontal 
drain/well was to test productivity in different landing zones. The objective of the vertical pilot section was data acquisition (core and full suite of logs) 
for reservoir characterization. 

The horizontal drains/wells have 2,000 m of lateral length and are currently being completed. The plan includes 33 frac stages in each of the laterals. 

Additionally, on October 12, 2018, by Decree No. 1,755/18, the province of Neuquén approved the assignment of a portion of the concession in favor of 
Statoil, thereby satisfying the conditions precedent set forth in the agreement. 

The plan for 2019 is to evaluate all potential landing zones in the central area of the block. The vertical wells drilled during the initial exploratory phase 
were used for landing zone selection. The wells will have 2,500 m of lateral drain. Microseismic monitoring is planned for all the wells. 

El Orejano Area: 

On September 23, 2013, YPF and Dow Europe Holding B.V. and PBB Polisur S.A. (our current 50% partner in the area) signed an agreement relating to 
the joint development of an unconventional gas pilot project in the Neuquén Province. 

The Project has been in the development phase since July 2016, and three targets are being drilled and produced. Through December 2018, 96 wells 
have been drilled and 81 wells have been put on line. During 2018, 10 horizontal wells were drilled, and 15 wells were put into production with a gross 
investment of U.S.$ 122 million in D&C and U.S.$ 6 million in production facilities 

Drilling time and well cost were reduced by 10% and 11%, respectively, between 2017 and 2018, with a reduction in development cost of 16% in the 
same period. 

February 2017 marked the startup of the UPS2 (Unidad de Separación Primaria 2), with the treatment and the separation capacity being upgraded to 4 
mmcm/d. A 16-inch Loop was built in the gas sale pipeline to Gas Pacífico Sale Point to increase gas transport capacity. A wellhead compression pilot 
began by the end of 2016 (2,900 HP installed) and the central compression is planned for 2019. 

Currently, a distance of less than 300m for wells at the same level (Cocina) is under evaluation due to the evidence of lower growth of the fracture wing, 
according to microseismic monitoring observations. 

Due to restrictions in gas treatment and evacuation capacity, in 2018 the production had a cap of 5.2 mmcm/d. The facilities to increase the treatment 
and evacuation capacity is expected to be available during 2019. 

By the end of 2018, the total field gas production was 4.3 mmcm/d (12% higher than December 2017). 

58 

Rincón del Mangrullo Area: 

In  the  Mulichinco  formation  at  the  Rincón  del  Mangrullo  concession,  Pampa  Energía  S.A.  (“Pampa  Energía”)  acquired  50%  of  the  working  interest 
during 2015. By the end of 2018, 124 wells (109 directed wells and 15 horizontal wells) were drilled in these marine tight sands, achieving an average 
gas production of 3.5 mmcm/d through a pipeline that connects to the Loma La Lata facilities. 

During 2018, five horizontal wells were drilled in a very tight zone and one vertical well in a tight zone was drilled with a standard design of 1,000 m 
lateral length and 7 frac stages for the first one. Drilling time and well cost were reduced by 10% and 6%, respectively, between 2017 and 2018, with a 
total investment of U.S.$ 47 million in D&C, and an additional U.S.$ 10 million expended on production facilities. 

On the other hand, the Vaca Muerta Formation in this block is 100% owned by YPF. During 2017, one vertical pilot well and three horizontal wells 
were drilled targeting the Vaca Muerta formation. The objective of the vertical well was data acquisition and landing zone definition. The objective of 
the horizontal  wells  was  to  test productivity in three  different landing  zones  across the  Vaca Muerta  organic rich  section.  The three horizontal wells 
were  put  into  production  by  the  end  of  September  2017.  Two  of  the  wells’  production  levels  have  exceeded  expectations  and  the  other  one,  below 
expectations while the third has fallen short of meeting expectations. 

During 2018, one vertical well was drilled and five more horizontal wells were drilled and stimulated in the block targeting the organic-rich section of 
Vaca Muerta. All the wells are pending completion, that is expected in 2019. In addition, a four-well PAD began to be drilled in 2018, which we expect 
to be completed and put into production in 2019. 

Aguada de la Arena Area: 

On May 13, 2016, YPF and Pampa Energía executed an agreement that subjects them to certain conditions precedent under which, upon closing of the 
acquisition by Pampa Energía of a controlling stake in Petrobras Argentina S.A (“PESA”). PESA will assign to YPF certain participating interests in 
two  exploitation  concessions  in  areas  with  gas  production  and  significant  gas  development  potential  (tight  and  shale)  located  in  the  Neuquina  basin, 
which shall be operated by YPF. The conditions previously mentioned, and the assignment to YPF of the participating interest were concluded during 
2016.  As  a  result,  the  participating  interests  acquired  were:  (i) a  33.33%  participating  interest  in  the  Río  Neuquén  block  located  in  the  province  of 
Neuquén and the province of Río Negro and (ii) an 80% participating interest in the Aguada de la Arena block located in the province of Neuquén. In 
addition, on February 23, 2017, YPF and PetroUruguay S.A. signed a definitive agreement for the transfer of a 20% participating interest in the Aguada 
de la Arena area. As a result, YPF has increased its participating interest in the Aguada de la Arena area to 100%. 

By the end of 2016, 14 wells were operating in the Mulichinco formation. During 2017 and 2018 there was no activity in this formation. 

During 2018, six horizontal wells were drilled, out of which three were completed with performance exceeding expectations (and the other three are 
expected to be completed during 2019). 

Activity in this area in 2018 involved a gross investment of U.S.$ 51.6 million in drilling and completion (D&C) and U.S.$ 16 million in production 
facilities. 

In 2019, a PAD of one vertical well and three horizontal wells from the pilot phase will be drilled, and nine horizontal wells will be put into production. 
An extended test is planned in the northeast area in order to evaluate the initial productivity, determine the gas oil ratio (GOR) and to take a PVT sample 
to characterize the reservoir fluid (Dewpoint and Liquid Drop Out). 

The field has restrictions on gas treatment and evacuation capacity. It is expected that the necessary facilities will be built during 2019. The accelerated 
development of the field was postponed to 2020 due to macroeconomic conditions related to the price of gas. 

La Ribera Area: 

This block, located in the center on the Neuquina basin, is 100% owned by YPF. The concession area comprises two separated regions: La Ribera I, 
covering 21.88 km2, and La Ribera II, covering 61.1 km2. Two vertical exploratory wells (one in each region) targeting the Vaca Muerta formation 
were drilled and completed in 2014. Both wells tested gas and condensate. During 2017, two horizontal wells targeting two landing zones in the Vaca 
Muerta  organic-rich  section  were  drilled  and  completed.  These  wells  were  connected  in  October  2017  and  one  of  them  has  obtained  results  in 
accordance with expectations. 

59 

During  2018,  two  horizontal  wells  were  put  in  production  showing  a  better  performance  than  expected.  Additionally,  one  vertical  (with  a  horizontal 
sidetrack) and one horizontal wells were drilled. The objective of the vertical well was to identify the number of landing zones at the extreme east of the 
block and the objective of the two horizontal wells was to confirm productivity and test drilling capability for the longest Lateral Length achievable in 
the block (2,350m). The horizontal wells will be put in production during 2019. 

Chihuido de la Sierra Negra Sudeste – Narambuena Area: 

During  April  2014,  YPF  and  subsidiaries  of  Chevron  Corporation  executed  a  new  agreement  with  the  objective  of  the  joint  exploration  of 
unconventional hydrocarbons in Neuquén, within the area Chihuido de la Sierra Negra Sudeste – Narambuena. During 2015, this activity began with the 
drilling and completion of two vertical wells that allowed for the defining of the location and landing zone for the horizontal well. This well was drilled 
at the end of 2015 and the beginning of 2016, covering 1,200m of lateral length at 2,400m of vertical depth, within the younger internal sequence of 
Vaca Muerta and becoming the first well in the basin with this objective. Subsequently, a third vertical well was drilled to delineate the extension of the 
area to the eastern sector of the block. By the drilling, completion and testing of these wells, the commitment for the initial phase of the project signed in 
April  2014  was  fulfilled.  During  the  second  half  of  2016,  the  joint  venture  between  YPF  and  subsidiaries  of  Chevron  Corporation  continued  the 
exploratory stage by evaluating the long-term tests of the horizontal well and third vertical well in this area located in the black oil window of the area. 
During 2018, there was no activity in the area. 

Non-Operated Areas—Development Activities: 

Aguada Pichana Este: 

This block is operated by Total S.A. YPF holds in this block a 27.2% working interest in the Mulichinco Formation, and a 22.50% working interest in 
the Vaca Muerta Formation. 

Tight gas projects: during 2018, we continued with the tight gas development in Aguada Pichana Norte (“APN”) in the North of the block and three

Octógono Block: 

Continuing  with  the  activity  of  2017,  during  2018  five  wells  were  drilled  in  the  northern  area  of  the  field  targeting  gas-bearing  intervals  in  Lajas 
formation. Three had positive results and the other two are being studied for optimization. 

In May 2018 we started the waterflooding in Campamento Dos field. We are injecting in two pilots in Challacó formation. 

During 2019, we are planning three workovers in Basamento formation. 

Al Norte de la Dorsal Block: 

Guanaco field: During 2018, two wells were carried out (1 drilled in 2017 and completed in 2018 and one drilled and completed in 2018). One with 
positive result and the other is under study due to low productivity. No activity is planned for 2019. 

Cerro Bandera Block: 

On November 22, 2017, YPF entered into an assignment agreement with Oilstone Energia S.A., in respect of 100% of the exploitation concession in the 
Cerro Bandera area. YPF holds La Via field and the exploration concession in Vaca Muerta and Los Molles formations. 

No rig activity was performed in 2018. 

Anticlinal Campamento Block 

During 2018, the gas well drilled in 2017 in Chachil formation, was completed with negative results. No drilling activity is expected during 2019. 

Loma La Lata – Sierra Barrosa Block: 

Loma La Lata field: During 2018 we drilled 10 gas wells in Sierras Blancas formation (six vertical and four horizontal wells), of which six wells were 
completed,  and  four  of  which  are  already  in  production,  with  an  achieved  production  rate  according  to  expectations.  The  other  four  remaining 
completions are planned to be finished in the first quarter of 2019. 

During 2019, we are planning to drill 17 wells targeting gas-bearing intervals in Sierras Blancas. 

The goal of this project is to design a field development plan for Vaca Muerta formation in the western area of Loma La Lata – Sierra Barrosa block. It 
was divided into stages. The first stage includes the drilling of six wells aiming to investigate a) the number of productive layers and their productivity, 
b) the type of fluid (oil or gas) and c) to get data to reduce uncertainty for future development. During 2018, the first two wells were drilled, and their 
completion in scheduled for the first quarter of 2019. 

Aguada Toledo–Sierra Barrosa field: Tight gas segment 5 (Lajas formation) 

During 2018, seven wells were drilled in Lajas formation (1 was horizontal). One of the wells is in study phases and therefore not producing, while the 
rest are already in production. 

Additionally, one well was drilled in Pre-Cuyano and Lajas formations. It produces from Pre-Cuyano and results were below than expectations. 

No drilling activity is expected during 2019. 

63 

Barrosa Norte tight gas field (Lajas formation) 

One vertical gas well was drilled with positive results. This well is in production and its productivity is above the type well. No activity is planned for 
2019. 

Los Caldenes Block: 

Manzano Grande field, oil target: In order to continue with the activity in the oil block, in 2018 we drilled two wells in the Manzano Grande block. They 
are currently in production. 

Los Caldenes field, gas target: two developing wells were drilled during 2017. One completion was achieved during the first quarter of 2018. 

Due to the lack of gas demand, the facilities to extract the gas (consisting of a connection with Pta. Entre Lomas) which were scheduled for 2019, were 
postponed to 2020. 

Estación Fernández Oro (“EFO”) 

During  2018,  several  projects  were  completed  that  allowed  an  increase  in  production,  treatment  and  compression  capacities.  With  respect  to  drilling 
activity, we completed 28 gas wells targeting the Lajas formation, in general with positive results for the development wells. 

The main objective of the activities conducted during 2018 was the expansion of the gas treatment capacities, the compression and transport plants. The 
most relevant projects were the following: 

•

•

•

•

Construction and assembly of an LTS (Low Temperature Separator) EFO plant 

Construction of a new gas pipeline for the sale of EFO plant to NEUBA I trunk gas pipeline 

Expansion of the low and ultra-low pressure compression plant 

Separator Revamp in Battery 2 ultra-low pressure Compressor Entry Scrubber and Expansion of the Gathering Network 

The development of the gas field will continue during 2019, focusing on drilling activity, where 21 new wells are scheduled to be completed. 

Rio Neuquén block: 

During 2017, the four wells drilled in 2016 were completed, all of them above the average estimated production. An Integral Field Development Plan 
(FDP) was defined, considering appraisal, infill and development sub-projects. The goal of these projects is to define the optimum production rate. In 
any case, from the proposed plan investments will be made in facilities to increase the production capacity from 3.5 up to 5.5 million cubic meters per 
day. As a result of the FDP six wells were drilled during 2017 (2 of them were already completed, one of them with initial production rate above the 
expected average and the other was an appraisal with results under expectations). 

Following a proposed Integral FDP, during 2018, four wells were drilled and completed in 2017 (one well was for delimitation and the other three for 
development, all with positive results). During 2018 a total of 12 wells were drilled: (four of which were drilled in 2017 and completed in 2018, and the 
remaining eight were drilled and completed in 2018). Of those wells, there were three delineation wells, with satisfactory results and nine development 
wells, three with results according to the type well, three with few data production up to date, one currently in process of completion and two of them 
were finished in 2019 with positive results. 

Works  were  carried  out  in  the  area  that  allowed  to  increase  the  compression  capacity.  The  LP  (low  pressure)  gathering  network  was  built  partially, 
following the development and location of new wells. The Gathering Ultra Low-Pressure Network will continue in 2019.

Operated Areas 

Barrancas block: 

The drilling activity during the last years focused in the following fields: 

Barrancas: During 2018, the development of the northwest zone continued in order to expand the area discovered in 2014. The objective is the 
Barrancas formation.  Three  wells were drilled, but the results were  below expectations.  Given these results, this development  project has been 
temporarily  suspended  to  re-evaluate  the  opportunities  of  the  field.  In  turn,  the  activity  for  the  optimization  of  secondary  recovery  continued 
through three conversions to water injector and the re-intubation of a one injector well. 

Ugarteche:  The  area  restarted  its  activity  in  2015  after  10  years  without  drilling.  Until  2017,  the  project  included  four  wells  drilled  in  the 
Ugarteche  Occidental  area.  During  2018,  ten  wells  targeting  oil  were  drilled  and  three  workovers  were  made.  The  results  were  better  than 
expected. The total remaining project activity is expected to be executed between 2019 and 2021. 

Estructura Cruz de Piedra: During 2018, two oil wells were drilled, with results below expectations. Likewise, we continued the execution of 
the  project  of  secondary  recovery  expansion  towards  the  southwest  of  the  field  by  repairing  two  producing  wells  and  one  water  injector 
conversion. As results had been below expectations, the project has been temporarily suspended, while a re-evaluation is carried out. 

Mesa Verde block: 

In 2014, exploration well MV.x-1 revealed the Río Blanco formation to be a productive horizon. The exploitation concession of this block was 

obtained during the second half of 2016. This allowed us to drill an appraisal well, which confirmed the expansion of the field. 

In  2017,  the  delineation  and  development  continued  with  the  drilling  of  nine  wells  (between  advanced  and  development  wells)  with  results 

according to expectations. 

During 2018 the development of  Zone 1  (Middle Zone) was  completed  through  the drilling of  seven  wells and two  workovers,  with  results  as 

expected. 

The mineralized area is not yet fully delineated. The project includes the study, delineation and development of Zone 2 (Eastern area of the block) 

and includes the future drilling of oil wells. 

La Ventana block: 

Between 2015 and 2017, a new integrated static-dynamic model of La Ventana Central was developed in Vacas Muertas. Through this study, a 
Secondary  Recovery  Optimization  Project  was  created.  The  objective  of  the  project  aims  to  improve  both  the  aerial  and  vertical  efficiency  of  the 
Secondary Recovery Project through the drilling of 21 wells and 45 workovers during the upcoming years. The project began its first phase in 2018, 
with the drilling of three wells. In these wells, were made special profiles (log profiles) and crowns were made, to capture new information and reduce 
uncertainties of the project. Depending on the results obtained from these wells and the analysis of the information obtained, the rest of the drilling and 
workover activity will be carried out during the upcoming years, as well as the adequacy and revamping of the surface facilities. 

Additionally, La Ventana was selected as part of a regional study to the Barrancas formation to develop EOR (tertiary recovery) with the objective 
of determining if it is convenient to start with a pilot project. During 2016, the identification of the SP formulation (Surfactant Polymer) compatible with 
the temperature and salinity of the formation was made. In 2018 the activity of SWTT (Single Well Tracer Test) was carried out, in order to test the SP 
formulation  identified.  Positive  results  were  obtained  confirming  that  a  reduction  in  the  range  of  40%  to  50%  of  the  residual  oil  saturation  can  be 
achieved. A pilot of four patterns of secondary recovery with a five spot arrangement will be carried out, initiating well activity during 2019 and the 
injection of SP from 2020. 

67 

Vizcacheras block: 

During 2018, one well was drilled in Vizcacheras Mainfield with the objective of Papagayos Fm. whose productive results were as expected. In 
addition, one producer well targeting oil was drilled in the northern area of Cañada Dura, which was abandoned due to its classification as unproductive. 

Additionally,  Vizcacheras  was  selected  as  part  of  a  regional  study  to  the  Barrancas  formation  to  develop  EOR  (tertiary  recovery)  with  the 
objective  of  determining  whether  it  is  convenient  to  start  a  pilot  project.  During  2016  the  identification  of  the  SP  (Surfactant  Polymer)  formulation 
compatible with the temperature and salinity of the formation was made. During 2017 and 2018, two single well tracer tests were carried out to test the 
potential  of  the  formulation.  Positive  results  were  obtained  confirming  that  a  reduction  in  a  range  of  40  to  50%  of  the  residual  oil  saturation  can  be 
achieved. According La Ventana SP pilot results, other SP pilots are expected to start in Vizcacheras Block during 2021. 

Llancanelo Block: 

During 2018, there was no drilling activity in this heavy oil field since the new corporate agreement within the joint venture was not achieved. 

The behavior of the bottom heater in the well Ll-2012(h), installed in 2017, continued to be evaluated. The aim of the heater is to improve the 
productivity of the well by increasing the mobility of the oil. The initial preliminary results were above productivity expectations, so we are evaluating 
to install heaters in other wells. 

In 2019, we plan to drill four horizontal oil wells, two advanced horizontal oil wells and two multilateral oil wells of five horizontal branches 

each. 

Cerro Fortunoso Block: 

During 2018, the development for secondary recovery of the Northern Block of the field was completed by drilling four water injector wells, three 

oil wells and two water conversions. The results obtained are in accordance with those expected. 

In the Central East South Block, one injector well was drilled, five oil wells were repaired, and four wells were converted to injectors. The results 

obtained are in accordance with those expected. 

In 2019 we plan to drill one well and the conversion of six more wells to complete the secondary recovery arrangement. 

Valle del Río Grande Block: 

During 2018, after visualizing the development opportunity for the productive formation “Neuquén Group” in the Malal del Medio Oeste field, 
three advanced oil wells were drilled during the conceptualization stage to obtain information and delineate the size of the opportunity. The two wells 
that were drilled in the Northern Plunge of the structure were unproductive, while the well located in the South Sector was productive for oil. 

With  the  results  obtained  in  this  stage  of  conceptualization,  the  project  of  delineation  and  development  of  this  field  is  being  reinterpreted  and 

reformulated, and no activity is planned for 2019. 

Chihuido Sierra Negra Block: 

Desfiladero Bayo: 

The Secondary Optimization project that started in 2016, which included injection well workovers, wellhead acids, the adequacy of the injection 

facilities (with the installation of a Water Injection Plant) to guarantee the water quality required, allowed the recovery of 

68 

production  to  the  expected  volumes.  During  2018,  two  producing  wells  were  drilled  and  14  workovers  were  made  and  the  results  obtained  are  in 
accordance with those expected. At the same time, the Polymer Injection Pilot Project continues. It started in 2016 and included drilling of producing 
wells, injector conversions, and the construction and assembly of a polymer injection plant. Polymer injection began in August 2016. As of the date of 
this  annual  report,  a  change  in  the  vertical  injection  profile  has  been  observed  and  is  awaiting  the  oil  response  of  this  pilot.  During  2018,  in  the 
Desfiladero  Bayo  East  area,  four  wells  were  drilled  to  optimize  the  development  and  expand  it  to  the  northern  part  of  the  field.  The  results  were  as 
expected. Three appraisal wells were also drilled, but with negative results. As of the date of this annual report, another Polymer Injection Pilot is also 
being implemented. The drilling activity has been completed, and as of the date of this annual report the secondary recovery production baseline is being 
prepared. It is expected that the Polymer Injection Plant will be installed by the beginning of 2019. 

Puesto Molina: 

During 2017, the first appraisal well was drilled, achieving completion in 2018 in the Eastern Flank of the field where there is no production. As 
of  the  date  of  this  annual  report,  the  well  is  in  production  but  with  a  high-water  percentage,  so  the  project  is  being  reviewed  and  activity  has  been 
temporarily suspended. 

Chihuido Sierra Negra: 

During 2017, in this mature field, a 3D seismic survey on the western area was carried out and its results are still under review. Additionally, to 
evaluate tertiary recovery potential, a single well chemical tracer test (SWCTT) and log-inject-log operation (assay technique) was performed during 
2018. It confirmed the prior positive results achieved in 2015 in displacing post water-flooding residual oil by an Alkali Surfactant Polymer formulation 
(ASP). During 2018 the main activities consisted of surveillance and maintenance of secondary recovery production project. 

Chachahuén Sur Block: 

During 2018, to complete the development of productive formations Rayoso Clástico Cycle 1, Cycle 2a and Cycle 3a, the drilling activity in the 
block continued with 52 new wells: 32 development oil producers, eight horizontal oil producers, three appraisals well, two extension wells and seven 
water injectors. The results were as expected, except in Cycle 1 which was below expectations. The secondary recovery project for Cycle 2a and Cycle 
3a is also under execution and results continue to be as expected. 

Cerro Morado Este Block: 

In 2016, YPF discovered the Cerro Morado Este field with the drilling of the CMoE.x-1 well, which was productive in the Centenario formation. 

During 2017 the delineation of the Cerro Morado Este field continued by drilling five extension wells. 

In 2018 YPF obtained the exploitation concession of this field. Four evaluation wells were drilled with positive results to delimit and estimate the 

productivity of block. Other evaluation wells are scheduled to be drilled in 2019. 

Cañadón Amarillo Block: 

During 2018, three wells targeting oil were drilled corresponding to the Cañadón Amarillo Somero project (La Tosca and Chorreado in both the 
North  and the  South areas). The  wells were drilled at the end of 2018 and are under evaluation. In addition, one  gas appraisal well was drilled with 
positive results. Drilling of five new wells is planned for 2019. 

Volcán Auca Mahuida and Las Manadas blocks: 

The development of the Centenario and Mulichinco formations continued. Five wells targeting oil were drilled during 2018 with results below 

expectations. Further appraisal and development wells are scheduled to be drilled in 2019. 

69 

Señal Picada – Punta Barda block: 

Señal Picada Field: During 2018, four wells were drilled with results as expected (3 oil development producers and one water injector). Drilling of 

nine new wells is planned for 2019. 

Punta Barda Field: During 2018, 14 wells were drilled with results as expected (10 oil development producers and four water injectors). 13 new 

wells are planned to be drilled during 2019. 

Non Operated Areas 

Puesto Pinto (CNQ7/A) and Jagüel Casa de Piedra Blocks: 

During 2018, 29 oil producing wells and 10 water injection wells were drilled to the Centenario Formation with results as expected, to continue 
with the water flooding project started in 2006. Most of the new wells were located in border zones, to expand the productive area of the project. For 
2019, 38 oil producer wells and 13 water injector wells are planned to be drilled. It is also planned to finish the construction of surface facilities for the 
expansion of the Polymer Injection Project, whose pilot was implemented in 2012. 

Gobernador Ayala (CNQ7) Block: 

During 2018, 17 oil producing wells and nine water injection wells were drilled to the Centenario Formation with results as expected, to continue 

with the development of secondary recovery project in the area, and the development of the new field Jagüel Casa de Piedra Sur. 

In  2019  we  plan  to  drill  17  oil  producer  wells  and  four  water  injection  wells  in  the  block.  During  2019,  surface  facilities  are  scheduled  to  be 

completed, and we also plan to start the injection of water in Jagüel Casa de Piedra Sur field. 

Campo Durán – Madrejones Block: 

In the period October 2017 - May 2018, two gas development wells were drilled in the Block and aimed at the Tupambi Bajo II Formation. The 

two wells resulted in the production of gas and condensate, as we expected. 

Due  to  these  results,  Tecpetrol,  the  partner  of  the  Joint  Venture  Aguaragüe  in  which  YPF  holds  a  53%  working  interest,  proposes  to  drill  two 

additional gas wells in 2019. 

Confluencia Sur Block: 

Towards the middle of 2017, one well was drilled, with the objective of the Troncoso Inferior Formation with good results. There was no activity 

during 2018 and no activity is planned for 2019. 

Sur Region 

During 2018, Sur Region production was 133.4 mboe/d, representing 25.2% of YPF’s total production.

Operated Areas 

El Trébol – Escalante 

During 2018, in El Trebol - Escalante, seven oil primary deep wells were drilled, with the objective of developing reserves in its three categories and 
incorporating new volumes, expanding the reserve, with positive results. 
Additionally, we began with the implementation of the secondary optimization project in El Trébol Area. This optimization was proposed by drilling 13 
wells (producers and injectors) closer to each other, thus improving the areal and vertical efficiency of the area. These drillings were carried out from 
existing locations, minimizing the environmental impact. Activity on the project started in the second half of 2018. 

Additionally, 15 interventions were carried out with workover equipment, for optimizations of both primary and secondary production and injection. 
These low-cost activities will have an aggregate annual result higher than expected. 

During 2019 we expect to continue to develop the area with deep wells and secondary recovery optimization. 

Zona Central – Cañadón Perdido 

This block is located in the urban area of Comodoro Rivadavia. 

Since 2016, there has been no drilling of wells, due to legal issues relating to a claim from a group of neighbors of the city regarding the extension of the 
Bella Vista Sur drilling project. The project was reformulated so that it can be executed in 2018, from another geographical location. 

During  2018  two  primary  directed  wells  were  drilled.  Within  the  framework  of  this  integral  project,  activity  was  carried  out  with  10  workovers  to 
implement the secondary recovery of the block. 

Restinga Alí 

During 2018, three horizontal wells that navigate in the Glauconitic formation, were drilled in the offshore zone of the coast. These wells were put into 
production during 2019. 

Manantiales Behr 

During  2018,  43  wells  were  drilled  (35  producers  and  eight  injectors).  The  projected  total  production  (EUR)  associated  with  primary  wells  exceeds 
expectation, being positive in both gas and oil. 

The Myburg block was one of the blocks with best results (9 producers and one injector). For this reason, activity in this area was accelerated for the 
year 2019. 

The drilling of the eight injectors of the Grimbeek Norte block was ahead of schedule during the first half of 2018. 

The  activity  associated  with  secondary  projects  in  La  Carolina  and  El  Alba  blocks  was  postponed  to  the  last  quarter  of  2018  due  to  delays  in  the 
issuance of environmental permits by the application authority. 

Progress was made with the manufacturing of five mobile Polymer Injection plants and associated facilities, which will allow us to advance the tertiary 
development of the GBKII and GBK Norte blocks during 2019. 

The workover activity was accomplished in 55 primary wells, with positive results. 

Cañadón Seco 

During 2018, 14 wells were drilled (12 producers, where 3 operated above expectations, two in order with expectations and seven below expectation, 
and two injectors with positive injectivity). Furthermore, 34 workovers were executed, including 14 conversions into injectors (one of which could not 
be finalized due to bad well integrity), and 20 producers (nine with results below expectations, and 11 consistent with expectations). The drilling activity 
was concentrated in Cañadón Seco, Caleta Olivia and Mina El Carmen formation. Additionally, we continue the investigations in the D-129 geological 
formation (an important formation from which studies are demonstrating its potential and the results of the activities carried out so far encourage us to 
continue with the planned activities). During 2019 we plan to take samples of rock and fluids to characterize better the D129 Formation and decrease the 
risk of the area with a new project, to be able to propose a development plan in the medium term. From the point of view of improved recovery, the 
objective 

72 

continues  to  center  on  the  geological  formation  of  Cañadón  Seco.  Several  projects  were  executed,  some  of  them  still  ongoing,  in  which  injection  is 
expanded horizontally as well as vertically, improving the efficiency in the production-injector wells relationship. In addition, we continue to expand the 
secondary  recovery  in  the  Mina  El  Carmen  Formation,  which  has  the  challenge  of  higher  depth  and  injection  pressures  than  those  required  for  the 
Cañadon Seco formation. 

Barranca Baya 

During 2018, 51 workovers (mainly secondary recovery objectives) were executed with results as expected. 

We deepened the secondary recovery control, in addition to the integrity of the facilities, which allows us to obtain a better quality of the water that is 
injected into the formations. We also began expanding the deeper injection in Castillo formation, as well as the usual Bajo Barreal zone. 

Las Heras 

During 2018, 11 workovers were executed, which include six conversions (one of which could not be finalized due to bad well integrity) into injectors 
with positive injectivity, and five producers (two with lower production than expected and three which met expectations). The activity was focused on 
the secondary recovery projects. The projects continued to be expanded both horizontal and vertically, incorporating both new layers to be flooded and 
optimizing the existing secondary recovery, with activity in cleaning injectors, re-layering and maintenance of the installation in the well. 

Lomas del Cuy 

During 2018, in order to continue the development of D-129 formation in El Guadal Sur field, three advanced wells were drilled and tested, and we plan 
to drill three more during 2019. 

Additionally, 29 workovers were executed with primary and secondary recovery objectives and we continue improving quality of water injection. The 
results were below expectations. 

In 2019, we plan to conduct three new secondary recovery optimization studies in Estancia San Justo, Anticlinal Perales Sur and El Guadal Bat.2 aimed 
to be implemented in 2020. 

Los Perales - Las Mesetas 

During 2018, two wells (including one injector and one producing well of polymer project) were drilled and 106 workovers were executed, with results 
as expected. The potential of this polymer project is important for the area and the company overall because the potential of production, the associated 
resources and the capacity for expansion is promising, not only in this field but also in other fields. 

Secondary  activity  is  present  in  all  blocks;  although  we  have  injected  water  only  in  the  Bajo  Barreal  geological  formation.  We  have  focused  on 
maintaining the existing secondary and expanding projects from the vertical and aerial point of view, incorporating new layers and completing existing 
meshes. During 2018 17 water supply wells were intervened in order to provide the necessary water for the development of the field with mixed results. 

The first polymer injection project was started in the Santa Cruz region in Los Perales Central Block III block. The project began on December 2017 
with a first phase: “Injectivity Test”, aimed to reduce critical uncertainties. The injection test was performed during 2018, using injection units provided 
by the companies TIORCO and NALCO. The project continues in 2019 to the next phase with two pilots, which include: drilling of 12 new wells, the 
workover  of  another  23  wells,  the  installation  of  two  full  modular  Polymer  Injection  Units  (constructed  in  France)  and  a  water  treatment  unit 
(constructed by Water tectonics). Drilling activity started in January 2019 and injection activity is expected to begin during the second half of 2019. 

Cañadón Yatel 

During  2018,  23  wells  were  completed,  22  were  drilled,  and  seven  workovers  (six  of  them  initiated  in  2017)  were  executed  with  results  below 
expectations. Drilling activity was concentrated at the Estancia Cholita field mainly in southern and central blocks where the development of a new area 
that targets an oil zone in D-129 formation. We also changed the strategy of well completions, increasing from three to six hydraulic fractures per well 
on average.

The electrification of the block began in 2016 and continued during 2017 and 2018 allowing us to exploit the wells with greater reliability, minimizing 
downtime and reducing lifting costs. Electrification activities are planned to continue during 2019. 

Tierra del Fuego 

Since 2016, the drilling activity in Tierra del Fuego focused on gas in the Lago Fuego field. 

The main objective was the exploitation of the Springhill formation and the exploration of the Tobífera series. We drilled four wells during 2018 (2 core 
samples  were  taken  during  drill  operation),  and  we  completed  four  (1  depleted  well  was  closed),  where  fracking  and  flow  back  programs  are  being 
analyzed in order to improve productivity. The results were below expectations. Additionally, source rock “Pampa Rincon” and “Margas Chicas” was 
studied. 

Other activities in the San Sebastian field were aimed at improving the production of gas through the installation of compressors, dewatering artificial 
lift  systems  such  as  capillary  injection  and  the  optimization  of  the  vertical  performance  with  high  water  gas  ratio  wells.  These  activities  slowed  the 
declining output in the field, as expected. 

Non-Operated Areas - Development Activities: 

Magallanes block: 

On November 17, 2014, we agreed to extend the joint venture contract with ENAP Sipetrol Argentina S.A. in the Magallanes block. The objective of 
this agreement was to extend the rights and obligations of ENAP in the original joint venture agreement and confirm its role as operator, maintaining its 
50% share until the end of the concession. On January 8, 2016, the Argentine government approved a concession extension through November 17, 2027. 
See “—Main Properties.” 

During 2017, we continued to develop an incremental production project, known as the “PIAM-Magallanes Block Incremental Project.” This project 
aims to increase the production capacity of the area by approximately 1.6 mmcm/d of gas with the startup originally expected in 2017, but effectively 
began in June 2018. During 2017, we signed an Engineering and Procurement Contract (EPC) to manage the engineering tasks. This project involves 
laying a marine pipeline and expanding compression capacity. The total value of the project was U.S.$ 401.3 million. 

El Tordillo and La Tapera-Puesto Quiroga blocks: 

Beginning in January 2014, under an agreement with the province of Chubut related to the negotiation of an extension of YPF concessions there, we 
transferred 41% of our working interest in the joint venture, El Tordillo and La Tapera-Puesto Quiroga, to Petrominera Chubut S.E. As a result, our 
interest in the joint venture will decrease from 12.196% to 7.196% in 2020. 

During 2016 and 2017, no Wells were drilled due to the low price of oil. 

In 2017 a new agreement was signed with Chubut Province, in which the future compliance scheme of pending investments was established, under the 
agreement for the implementation of an activity commitment and investment in hydrocarbon areas of Chubut Province. 

During  2018,  in  order  to  restore  activity  in  the  area,  nine  wells  were  drilled.  In  2019  we  plan  to  drill  17  wells  incorporating  additional  drilling 
equipment, with a total of two drilling rigs. 

Properties and Exploration and Production Activities in Rest of South America 

1.

Bolivia: On July 26, 2017, the formalization of the contract with YPFB originally signed in January 2017 was signed, to begin exploration 
work in Charagua, Bolivia, in a block that has a potential in natural gas resources. In addition, one exploration block was awarded in 2017 
(Charagua Block). Activities to fulfil commitments have already started in 2018. YPF holds a 100% working interest in the Charagua Block. 
However, a partnership agreement has been signed by YPF and YPFB Chaco, whereby YPF would operate holding a 60% working interest 
and YPFB Chaco would hold 40%. As of the date of this annual report, both parties are still waiting for the Legislative Assembly of Bolivia 
to formalize the agreement.

2.

Colombia:  Blocks  COR 12  and  COR  33  are  located  in  the Cordillera  Oriental  basin,  which  we  operate  pursuant  to  authorization  by  the 
Colombian National Hydrocarbons Agency (Agencia Nacional de Hidrocarburos or “ANH”). Our working interest is 60% in COR 12 and 
55% in COR 33. The combined net acreage in these blocks is 700 km2. We and our partners informed the ANH of our decision to relinquish 
both blocks. As of the date of this annual report, the parties are in the process of formalizing and executing the final agreements for the 
relinquishment. 

3.

Chile: From the results obtained in San Sebastián Block we did not foresee any new exploratory opportunities so we: 

•

•

•

•

Asked  the  National  Authority  for  the  commercial  exploitation  concession  of  only  a  portion  of  the  area  where  wells  with  positive 
results had been drilled. 

Informed  the  National  Authority  of  our  decision  not  to  enter  the  Third  Exploration  Period,  and  to  relinquish  the  rest  of  the  area 
except for 3,000 acres needed to finish the testing of one exploration well. For this exception, we have requested a period of two 
years, starting on December 2017. 

We started well testing during 2018 oil production at Carpintero x1, with results in line with expectations. However, it had to be 
closed from October 17, 2018 until January 17, 2019 as consequence of the Cullen spill. 

Cullen spill (Chile): in storage facilities of YPF in Chile (Cullen plant), a hydrocarbon spill was detected in a pump room. The spill 
was controlled, and the sanitation tasks finished on November 18, 2018. 

Additional information on our current activities

During 2018, our downstream activities included crude oil refining and transportation, and the marketing and transportation of refined fuels, lubricants, 
LPG, and other refined petroleum products in the domestic wholesale and retail markets and certain export markets. 

During 2018, the downstream segment was organized into the following divisions: 

•

•

•

•

•

Refining Division (oil refining and petrochemical production); 

Domestic Marketing (commercialization and marketing of refined products); 

Chemicals Division (commercialization and marketing of petrochemical products); 

Logistic  (transportation  of  oil  to  refineries  and  distribution  of  refined  and  petrochemical  products  to  be  marketed  in  the  different  sales 
Channels); and 

Trading Division (trading refined products and crude oil to international markets) 

We  market  a  wide  range  of  refined  petroleum  products  throughout  Argentina  through  an  extensive  network  of  sales  personnel,  YPF-owned  and 
independent distributors, and a broad retail distribution system. In addition, we export refined products, mainly from the port at La Plata. The refined 
petroleum products marketed by us include gasoline, diesel, jet fuel, kerosene, heavy fuel oil and other crude oil products, such as motor oils, industrial 
lubricants, LPG and asphalts.

Refining division 

We wholly own and operate three refineries in Argentina: 

•

•

•

La Plata refinery, located in the province of Buenos Aires; 

Luján de Cuyo refinery, located in the province of Mendoza; and 

Plaza Huincul refinery, located in the province of Neuquén. 

Our three wholly-owned refineries have an aggregate refining capacity of approximately 319,500 boe/d. The refineries are strategically located along 
our  crude  oil  pipeline  and  product  pipeline  distribution  systems.  In  2018,  our  crude  oil  production,  substantially  all  of  which  was  destined  to  our 
refineries, represented approximately 82.3% of the total crude oil processed by our refineries, while in 2017 it was 78.6%. Through our stake in Refinor, 
we also own a 50% interest in a 26,100 boe/d refinery located in the province of Salta, known as Campo Durán. 

The  following  table  sets  forth  the  throughputs  and  production  yields  for  our  three  wholly-owned  refineries  for  each  of  the  three  years  ended

During 2018, our global refinery utilization amounted to 88.81%, compared to 91.73% in 2017, based on a nominal capacity of 319.5 mboe/d. 

The  La  Plata  refinery  is  the  largest  refinery  in  Argentina,  with  a  nominal  capacity  of  189  mbbl/d.  The  refinery  includes  three  distillation  units,  two 
vacuum  distillation  units,  two  fluid  catalytic  cracking  units,  two  coking  units,  a  coker  naphtha  hydrotreater  unit,  a  platforming  unit,  two  diesel 
hydrofinishing  units,  a  gasoline  hydrotreater,  an  isomerization  unit,  an  FCC  (fluid  cracking  catalysts)  naphtha  splitter  and  desulfuration  unit  and  a 
lubricants complex, in addition to a petrochemical complex that generates MTBE, TAME and aromatics compounds used for blending gasoline, and 
other chemical products for sale. The refinery is located at the port in the city of La Plata, in the province of Buenos Aires, approximately 60 km from 
the City of Buenos Aires. During 2018, the refinery processed approximately 160.6 mbbl/d, with a capacity utilization rate of 84.96 % compared with 
172.3 mbbl/d processed in 2017, with a capacity utilization rate of 91.15 %. The lower capacity utilization compared to the previous year was a result of 
lower demand of fuel oil from power generation plants as there was more availability of natural gas in the period and scheduled maintenance stoppages 
in our industrial 

76 

complexes. The crude oil processed at the La Plata refinery, 84.83 % of which was YPF-produced in 2018, comes mainly from the Neuquina and San 
Jorge basins. Its crude oil supplies come from the Neuquina basin by pipeline and from the San Jorge basin by vessel, in each case to Puerto Rosales, 
and then by pipeline from Puerto Rosales to the refinery. 

A new Coke A facility that allowed for an increase in the conversion capacity was officially started up in September 2016, and the test run was made in 
October  2016.  The  capacity  of  the  new  unit  is  1,160  bbl/h  of  fresh  feed  pumped  from  the  bottoms  of  the  Topping  and  Vacuum  units,  providing  the 
refinery with an increase in crude processing of 23,800 bbl/d, representing an increase of almost 12% in the capacity utilization rate. The production of 
this facility is a component for the blend to be used in the generation of diesel, motor gasoline and coke. 

The Luján de Cuyo refinery has a nominal capacity of 105.5 mbbl/d, the third largest capacity among Argentine refineries. The refinery includes two 
distillation  units,  a  vacuum  distillation  unit,  two  coking  units,  one  fluid  catalytic  cracking  unit  (FCCU),  a  platforming  unit,  a  MTBE  unit,  an 
isomerization unit,  an  alkylation unit, an FCC naphtha  splitter, a hydrocracking  unit, an FCC  naphtha hydrotreater  unit and two  gasoil hydrotreating 
units. During 2018, the refinery processed approximately 99.7 mbbl/d, with a capacity utilization rate of 94.5% compared with 98.0 mbbl/d processed in 
2017, with a capacity utilization rate of 92.9%. 

Due to its location in the western province of Mendoza and its proximity to significant distribution terminals we own, the Luján de Cuyo refinery has 
become  the  primary  facility  responsible  for  providing  to  the  central  and  northwest  provinces  of  Argentina  with  petroleum  products  for  domestic 
consumption.  The  Luján  de  Cuyo  refinery  receives  crude  supplies  from  the  Neuquina  and  Cuyana  basins  by  pipeline  directly  into  the  facility. 
Approximately 78.4 % of the crude oil processed at the Luján de Cuyo refinery in 2018 (and 77.5% of the crude oil processed in this refinery in 2017) 
was produced by us. Most of the crude oil purchased from third parties comes from oil fields located in the provinces of Neuquén and Mendoza. 

The  Plaza  Huincul  refinery,  located  in  the  province  of  Neuquén,  has  an  installed  capacity  of  25  mbbl/d.  During  2018,  the  refinery  processed 
approximately 23.5 mbbl/d, with a capacity utilization rate of 94.1%, compared with 22.8 mbbl/d processed in 2017 with a capacity utilization rate of 
91.2%. 

The  only  products  currently  produced  at  the  refinery  are  gasoline,  diesel  and  jet  fuel,  which  are  sold  primarily  in  nearby  areas  and  in  the  southern 
regions of Argentina. Heavier products, to the extent production exceeds local demand, are blended with crude oil and transported by pipeline from the 
refinery to our facilities in La Plata for further processing. The Plaza Huincul refinery receives its crude supplies from the Neuquina basin by pipeline. 
In 2018, 19% of the refinery’s crude supplies were purchased from other companies, while 100% of such supplies were produced by us in 2017. 

According to Ministry of Energy regulations, sales of gasoline and diesel must be blended by biofuels. The gasoline requires a 12% blend of ethanol 
(Resolution No. 37/2016) and diesel requires a 10% blend of FAME (Resolution No. 1125/2013), the same blend request of 2017 and 2016. 

Since  1997  and  1998,  each  of  our  refineries  (La  Plata,  Luján  de  Cuyo,  and  Plaza  Huincul)  have  been  certified  under  International  Organization  for 
Standardization  (“ISO”)  9001  (quality  performance)  and  ISO  14001  (environmental  performance).  All  of  them  are  also  certified  under  the  OHSAS 
18001  (occupational  health  and  safety  performance)  standard.  Inventories  of  industrial  greenhouse  gases  and  savings  of  CO2  emissions  equivalent 
(MDL projects) have been verified in accordance with ISO 14064 in the three refineries (2009 La Plata and Lujan de Cuyo; 2017 Plaza Huincul). The 
refineries maintain their systems under continuous improvement and revision by authorized organizations. 

During 2018, the energy produced by renewable energy from the wind farm of Manantiales Behr (located in Chubut Province), represents 12% of the 
electricity  consumption of the Luján  de  Cuyo and La  Plata  Refineries. This park was  incorporated into the  matrix  of electricity consumption in July 
2018 and is owned by YPF Energía Eléctrica (YPF EE) (“See “Item 4. Information on the Company—Gas and Power—YPF in Power Generation.”). 

Marketing Division 

Our Marketing Division supplies gasoline, diesel, JET-A1 Fuel, lubricants, asphalts, LPG and other petroleum products throughout Argentina and other 
countries in the region. We supply several industries such as, retail, transport and agriculture.

During 2018, as a result of the macroeconomic situation in Argentina, there was a change in the performance of fuel sales. See “Item 5. Operating and 
Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions.” During the second half, registration of new vehicles 
(0 Km) decreased by 33% compared to 2017. This resulted in a direct adverse effect on the performance of fuel sales. 

YPF maintained its leading position in Argentina, reaching a market share of 57.9% for liquefied fuels. 

YPF  sells  two  types  of  gasoline:  Infinia,  a  premium  98  octane  gasoline,  and  Super,  a  regular  95  octane  gasoline.  As  a  result  of  a  change  in  market 
behavior, the high values of mix in 2017 (34.7%) were difficult to maintain reaching an annual average mix during 2018 of 31.4%. In the second half of 
2018, the mix fell to its lowest value in the month of November (26.0%). In December, the trend reverses, rising to 27.8%. 

Our market share of Infinia and Super gasolines, according to our estimates, was 61.5% and 53.8%, respectively, as of December 31, 2018, compared 
with 61.3% and 52.4%, respectively, as of December 31, 2017. Our sales volume for Infinia was 1,643 mcm in 2018 (7.4% less than in 2017) and 3,590 
mcm for Super in 2018 (7.4% higher than in 2017). 

With  respect  to  diesel,  according  to  our  own  estimates,  our  market  share  of  diesel  (500  and  1500  ppm)  and  Infinia  diesel  (10  ppm)  was  58.9%  and 
60.1%, respectively, as of December 31, 2018, compared with 56.5% and 57.6%, respectively, as of December 31, 2017. The greatest volume growth 
was in Infinia Diesel increasing 16.6% compared to 2017, as a consequence of the arrival of new vehicles to the country with the Euro 5 standard (with 
SCR technology) in the transport segment. Along with Infinia diesel (10 ppm), for which sales volume was 2,041 mcm in 2018 compared to 1,751 mcm 
in 2017, our diesel (500 and 1500 ppm) decreased sales volume of 5,853 mcm in 2018 compared to 5,946 mcm in 2017. This sales volume does not 
include  bunker  sales  to  the  foreign  market  and  sales  to  other  companies.  Accounting  for  such  sales,  sales  volume  of  diesel  (500  and  1500  ppm) 
increased 1.0% compared to 2017. Finally, sales volume of Infinia diesel reached 25.9% of total diesel sales volumes, up from 22.7% in 2017. 

Our main competitors are still active in communication, promotions, loyalty cards and bank discounts. 

Consequently, 2018 was a year during which YPF focused its efforts on three strategic pillars: construction of perceived quality, loyalty and closeness to 
the customer and the offer of a best value proposal for the customer. 

In connection with the creation of perceived quality, this was implemented through YPF’s authority program, which focuses its efforts on creating a 
strong  relationship  between  the  advisors  and  role  models  of  the  mobility,  fuels  and  lubricants  industry.  In  August  2018,  the  Infinia  Communication 
Campaign was carried out. Additionally, we sponsored the main car competition categories in Argentina, with particular focus on GM’s competition 
team (Super TC 2000). 

As  to  the  loyalty  and  closeness  to  the  client  pillar,  YPF  multiplied  the  efforts  of  the  Serviclub  program  with  proposals  from  alliances  and  special 
promotions during the World Cup and the creation of a campaign relating to reduced energy consumption through LED lightbulbs during October. In 
addition, we implemented special promotions during the summer and other regional campaigns aimed at specific targets such as millennials and women. 

In connection with the value proposal pillar, in 2018 its main drivers were: alliances with benefit clubs, national and regional banks and discounts in fuel 
prices for members of the Serviclub program. During the year we also carried out several campaigns impacting three million customers (distribution of 
soccer  balls  in  exchange  for  fidelity  points  or  cash,  and  promotional  activities  within  the  Lollapalooza  Festival),  we  sponsored  sporting  events  (car 
racing, national soccer team), and we furthered our relationship with opinion leaders of fuel matters, automobile care and products for the vehicle. 

The Domestic Marketing Division includes six main segments: Retail, Agriculture, Industry, Aviation, Lubricants and Specialties and LPG. 

Retail Division 

As  of  December 31,  2018,  the  Retail  Division’s  sales  network  in  Argentina  consisted  of  1,591  retail  service  stations,  compared  to  1,563  as  of 
December 31, 2017. Of these, 113 are owned by YPF. The remaining 1,478 service stations are associated service stations. OPESSA, our wholly-owned 
subsidiary, actively operates 166 retail service stations, of which 88 are owned by YPF, 22 are leased to the Automóvil Club Argentino (ACA) and 56 
are leased to independent owners. Additionally, YPF owns 50% of Refinor, a company operating 66 service stations. 

78 

According to our estimates, as of December 31, 2018, we were the main fuel retailer in Argentina, with 35.8% of the country’s gasoline service stations, 
followed by Shell, Axion and Petrobras with 14.4%, 12.3% and 5.4%, respectively. During 2018, our market share in diesel and gasoline, marketed in 
all segments, increased from 56.1% to 58.0%, from December 31, 2017 to December 31, 2018. 

Our convenience stores, YPF Full and YPF Full Express, are present in 492 and 70 points of sale, respectively, as of December 31, 2018. During 2018, 
we established 22 new sale points and implemented 80 new images in Full stores at service stations. Additionally, a modern oil change service shop 
called YPF Boxes is present in 299 service stations across the country. 

During  2018,  YPF successfully  renewed contracts with the operators of retail  associated service stations expiring within the year. We also signed  in 
advance 31 target contracts with expiration in 2019, assuring a 22% market share for the Company. During this time, an aggressive infrastructure plan 
was carried out, mainly to install 70% more fuel-tanks and pumps compared to 2017. 

In October 2018, YPF signed a new agreement with ACA allowing an extension in the lease of the retail service stations run by ACA through October 
2027. This agreement includes 22 service stations owned by ACA and operated by OPESSA.  This major event secures the maintenance of the 5.1% 
market share owned by ACA. 

We highlight the opening of 40 new service stations to our net, consisting of 20 new stations built by YPF and 20 new added through lease contracts 
compared to the 35 incorporations during 2017. 

During 2018, the operational process through which our customers have the possibility of requesting “cash back” in our stores, which consists of cash 
withdrawals  from  their  debit  accounts,  has  gained  relevant  importance.  This  cash  is  withdrawn  directly  from  the  employee’s  cash  register  which 
optimizes cash collection and increases savings by reducing costs of depositing cash in the bank. 

As  part  of  the  +  YPF  program,  on  September,  we  awarded  the  best  operators  in  the  network  with  a  training  trip  to  Disney  (Instituto  Disney).  This 
training focused on three pillars: excellence in leadership, employee commitment and quality service. In addition, in May, the POTENCIAR National 
Convention was held at the Costa Salguero site, where 1,645 people participated, including operators, heads of network stations and retail sales teams. 
This event was of great importance and it was resumed in 2018 after many years, whose main objective was to attract the network of YPF’s operators to 
accompany and invest in service stations network for the next 10 years. 

Agriculture Division 

The Agriculture Division provides an extensive portfolio of products and services to agricultural producers, including agricultural advice, delivery and 
application of products at the consumption site, under a unified brand image, directly or through a network of 103 sale points (nine owned by YPF) with 
exclusive  commercial  areas  in  19  provinces,  offering  diesel,  fertilizers,  lubricants,  phytosanitaries,  and  ensiling  bags,  among  other  products.  During 
2018,  YPF  released  eight  new  products  (phytosanitaries,  fertilizers  and  adjuvants),  under  the  YPF  brand.  The  agriculture  division  works  through 
distribution  agreements  with  leading  local and  international  suppliers.  This  year  our  market  share  of  fertilizers,  according  to  our  estimate,  was  9.4% 
compare to 9.6% (2017). 

YPF developed crop financing with instruments such as credit cards with local banks, for more than U.S. $ 128 million. We accept different types of 
grains as payment (exchange), mainly soybean, but also corn, rice, wheat, sorghum, sunflower, barley and blueberries. Some soybeans are processed by 
third-party companies to obtain soybean oil, meal and hulls that we generally export. Furthermore, part of the soybean oil is processed into fatty acid 
methyl esters (“FAME”) (a natural product added to commercial grade diesel), which covers approximately 11% of YPF’s refinery needs. During 2018, 
we received approximately 1.2 million tons of grains, primarily soybeans (a decrease of 16% compared to 1.5 million tons in 2017, as a consequence of 
the severe draught in the first quarter of the year. Nevertheless, this decrease was less than in soybean production which was around 35%), that positions 
YPF  among  the  top  five  exchangers  in  Argentina.  As  December 31,  2018  the  revenue  from  these  exports  represented  approximately  U.S.$ 
257.6 million, a 30.7% decrease compared with 2017. It is worth noting that in 2018 YPF was the tenth exporter in the Argentine market of soybean 
meal and oil. 

Industry Division 

This  division  supplies  the  entire  national  industry  and  transport  (ground)  sectors,  which  require  a  broad  portfolio  of  products  and  services  to  meet 
customer  needs.  The  division  develops  specific  solutions  for  mining,  oil &  gas,  transport  and  general  industries.  We  supply  products  such  as  fuels 
(diesel,  gasoline,  fuel  oil),  lubricants,  coal,  asphalts,  paraffin  and  derivatives  (sulfur,  CO2,  decanted  oil,  aromatic  extract),  either  directly  from  our 
refineries to the point of consumption (more than 10,000 direct customers) through our own ground and waterway network, or through a network of 22 
industrial distributors with national coverage (Mining, Oil & Gas and Asphalts). 

79 

Our mission is to promote efficiency in the value chains of the industries we serve through energy solutions, supplies and services. Accordingly, our 
strategy is based on close relationships with our clients and the development of innovative solutions focused on creating value for YPF and the region’s 
industries. 

During  2018  we  continued  to  implement  a  control  and  traceability  solution  for  the  gasoline  and  lubricants  consumption  which  was  offered  to  all 
industrial segments customers to improve efficiency in bulk fuel management. 

In the transport segment, we also entered into new commercial agreements (rental of the property and operation) with ConSer, ensuring the continuity of 
the commercialization of 2,500 cm per month of diesel. 

We have entered into a commercial agreement with AGP (General Administration of Ports) in order to install a base of operations in the Port of CABA 
(Autonomous City of Buenos Aires). 

Another  highlight  in  the  transport  segment  in  2018,  was  the  steady  growth  of  sales  through  the  YER  (YPF  en  ruta)  fleet  card,  which  resulted  in  an 
increase of 27% of volume sales compared to 2017, mainly as a result of certain incentive programs that were released. This card is designed to cover 
the supply and administration needs of vehicles of cargo and passengers. 

In  the  mining  segment,  in 2018 we  entered  into  an agreement  with  Sales de  Jujuy  S.A., for  diesel  supply,  for  a  term  of one  year,  with an  estimated 
demand of 600 cm per month of diesel. This year it was possible to close the deal of supply with renewable energies to Mina Aguilar (1400 MW / year). 
Finally, a pilot test of Veladero (Barrick) supply with LNG is being initiated. 

Through  the  general  industries  segment,  we  accompany  the  implementation  of  Strategic  Special  Operations  for  Argentina,  such  as:  G-20,  Youth 
Olympic Games 2018 and the First Stage Antarctic Campaign 2018-2019. 

As a result of a drop in the Argentinian market, during 2018 YPF asphalt sales were 244 thousand tons (68 thousand tons less than in 2017), reaching a 
market share of 42.1% (2.6% less than 2017). 

Aviation Division 

The Aviation Division provides JET-A1 Fuel in 52 airports and AVGas-100LL Fuel in 41 airports across Argentina. We have highly developed logistics 
that  include  150  trucks  and  a  pipe  line  from  La  Plata  Refinery  to  Ezeiza  Airport,  the  most  important  airport  in  Argentina.  In  2018  YPF  invested 
approximately U.S.$ 5,000,000 in new trucks and logistics equipment. 

YPF has a 57% market share of JET-A1 in Argentina and is the second supplier of JET-A1 in Santiago de Chile’s airport, with an 18% market share. 
Our sales volume for JET-A1 was 1,146 mcm in 2018, 8.1% higher than in 2017. 

During  2018  the  company  entered  into  agreements  for  the  supply  of  JET-A1  with  all  low-cost  companies  which  started  to  operate  in  Argentina 
(Flybondi, Norwegian Argentina, JetSmart, Avianca Argentina, Grupo LASA). We expect this market to increase in the near future. 

We  also  entered  into  new  agreements  with  Turkish  Airlines,  Ethiopian  Airlines  and  Norwegian  UK  for  the  supply  of  100%  JET-A1  volume  during 
2019. With American Airlines and KLM (with which we already had agreements during 2018) we completed a new agreement for the supply of 100% 
of their required volume during 2019. 

Lubricants and Specialties Division 

In  the  Lubricants  market,  YPF  has  a  leading  position.  We  manufacture  a  wide  range  of  products  including  Motor  Oil,  Heavy  Duty  and  Industrial 
lubricants in retail, wholesale and industrial markets through a net of dealers and distributors. In the La Plata industrial complex, we operate a modern 
and  efficient  manufacturing  facility  where  we  produce  lubricants  not  only  for  the  domestic  market,  but  also  for  export.  Our  line  of  automotive 
lubricants, including mineral and synthetic oils, has received approval and recommendations from leading global automotive and engine manufacturers, 
including Ford, Volkswagen, Renault, Audi, Deutz, Cummins, Volvo, MAN Truck, GM, Porsche, Scania, Detroit Diesel and Caterpillar. 

80 

During 2018, our sales of lubricants decreased by 5.7% compared to 2017. Sales to the domestic market fell by 7.3%, and sales to the foreign market 
increased by 6%. The reason for the drop in Lubricants sales was due to a collapse of the market, as a result of a severe economic recession in Argentina 
during 2018. 

Exports are made to two large groups. On the one hand, we sell to our wholly-owned companies in the main markets of Brazil and Chile, where the 
volume  sold  increased  54%  in  Brazil  compared  to  2017,  because  exports  were  made  to  cover  problems  with  the  supply  of  premium  materials,  and 
increased 1% in Chile compared to the previous year. On the other hand, we export to our network of distributors located in Bolivia, Uruguay, Paraguay 
and Ecuador, where sales volume was 9% higher than in 2017. 

YPF’s strategy is to continue its leadership in the development of lubricants, to meet the latest generation OEMs (original equipment manufacturers) 
requirements  for  protection  and  performance  needs  in  both  passenger  and  heavy-duty  vehicles,  maintaining  the  leadership  in  a  high-profitability 
lubricants market. Our market share as of December 31, 2018 was 39.4% (a decrease of 0.1% compared to 2017) according to information provided by 
the  Secretary  of  Energy  (formerly  Ministry  of  Energy).  The  critical  factors  of  competitiveness  are  the  usage  and  referral  agreements  from  the  main 
OEMs (Ford, General Motors, Porsche and Scania) and reaching the customer with the best network and service coverage. 

The sales of our passenger car motor oil (PCMO) line (Elaion is the most important brand for the automotive segment) reached 12.5 mcm in 2018, a 
decrease of 11.6% compared to 2017. With respect to our heavy-duty motor oil (HDMO) line (Extravida), 2018 sales decreased by 8.7% compared to 
the previous year. 

In order to meet the technological update required by new vehicles that comply with the Euro 5 standard (with SCR technology) of mandatory use in the 
country for all new vehicles and complemented by the launch of Infinia Diesel and XV500 Extravida, we launched our Nitrous Oxides Reducing Agent 
(ARNox).  Azul  32  is  the  commercial  name  of  a  new  product  used  in  vehicles  that  comply  with  the  emission  standard  EURO  5  (serves  to  reduce 
emissions of gases into the environment). The sales of Azul 32 increased 47% compared to 2017. 

Our quality controls ensure that the product reaches the customer in optimal conditions and complies with the strict standards determined by ISO 22241 
for  this  product.  Since  1995,  Lubricants  and  Specialties  has  been  awarded  with  ISO  9001:  2008,  ISO  14001:  2004,  OSHAS  18.001:  2007  ISO  /  TS 
16949-Third certifications. Also, YPF has obtained for our Azul 32 API’s certification as part of the American Petroleum Institute (API) Diesel Exhaust 
Fluid Certification Program. 

LPG Division 

We are engaged in the LPG wholesale business, which encompasses LPG storage, logistics and commercialization to domestic and foreign markets. We 
obtain LPG from natural gas processing plants and refineries, as well as from third parties. In addition to butane and propane, we also sell propellants 
used in the aerosols manufacturing processes. 

During 2018, we sold approximately 35% of our LPG production to YPF Gas S.A. for the domestic market. 

We  are  the  largest  LPG  producer  in  Argentina,  with  sales  in  2018  reaching  approximately  616  mtn,  compared  with  579  mtn  in  2017.  Of  this, 
approximately 371 mtn were sold in the domestic market, compared to 402 mtn in 2017. Our main clients in the domestic market are companies that sell 
LPG  in  cylinders  or  bulk  packing  to  end-consumers,  also  providing  LPG  to  households  in  some  regions.  Additionally,  exports  in  2018  reached 
approximately 245 mtn, compared to 177 mtn in 2017. The main destinations were Chile and Paraguay. Transportation of LPG to overseas customers is 
carried out by truck, pipeline and barges. 

Total sales of LPG, excluding LPG used as petrochemical feedstock, were Ps. 9,282 million and Ps. 3,547 million in 2018 and 2017, respectively. 

81 

We produced 569 mtn of LPG in 2018, not including LPG destined for petrochemical usage, and purchased LPG from third parties, as detailed in the 
table below:

San Sebastian, El Portón, Loma Negra and EFO are 100% owned by us; General Cerri belongs to a third party with which we have a processing 
agreement. 
This production does not include LPG used as petrochemical feedstock (olefins derivatives, polybutenes and maleic). 
Purchased from Refinor. We also have a 50% interest in Refinor, which produced 187.5 mtn of LPG in 2018. 

Regarding sales prices, the butane local market is regulated by the government. In April (Disposition No. 5-E/2018) the government updated Butane’s 
maximum reference prices for the local market recognizing an improvement in sales prices. In the case of propane, although the market is also regulated 
by the government, local prices published by the former Ministry of Energy and Mining are referred to export parity. 

Chemicals Division 

Petrochemicals are produced at our petrochemical facilities in Ensenada and Plaza Huincul. 

Petrochemical  production  operations  in  the  Complejo  Industrial  Ensenada  (“CIE”)  are  closely  integrated  to  the  refining  activities  at  the  La  Plata 
refinery, allowing a flexible supply of feedstock, the efficient use of by-products, such as hydrogen, and the supply of aromatics to increase gasoline 
octane levels.

Natural  gas,  the  raw  material  for  methanol,  is  supplied  by  our  Upstream  business  segment.  The  use  of  natural  gas  as  a  raw  material  allows  us  to 
monetize reserves, demonstrating the integration between the Chemical and the Upstream divisions. 

In 2018 we signed an agreement with Methanex (one of the biggest global methanol producers) to produce nearly 110,000 tons of methanol in their 
Chilean  facility,  with  YPF’s  natural  gas  as  raw  material.  This  additional  production  of  methanol  allowed  us  to  increase  our  methanol  sales  by  52% 
compared to 2017, mainly through exports to the Brazilian market. 

Raw materials for petrochemical production in the CIE, including virgin naphtha, propane, butane and kerosene, are supplied mainly by the La Plata 
refinery. 

In 2018, 2017 and 2016, 67%, 84% and 80%, respectively, of our petrochemicals sales (including propylene), were made in the domestic market, while 
we exported to Mercosur countries, the rest of Latin America, Europe and the United States. 

The  La  Plata  petrochemical  plant  was  certified  under  ISO  9001  (2018),  ISO  14001  (2014),  OHSAS  18001  (2014),  ISO  50001  (2015)  and  the  plant 
verified  the  inventory  of  CO2,  CH4  and  N2O  emissions  under  ISO  14064  (2011).  The  CIE  laboratory  was  certified  under  ISO  17025  (2013).  The 
methanol plant was certified under ISO 9001 (2016), ISO 14001 (2016) and OHSAS 18001 (2014). 

The certification of our petrochemical business covers the following processes: 

•

refining process of crude oil and production of gas and liquid fuels, base stocks for lubricants and paraffin, petroleum coke (green coke) and 
petrochemical products in the units of refining, conversion, lubricants, aromatics, olefins PIB / Maleic and LAB / LAS, methanol production 
and storage.

• Management  and  development  of  our  petrochemical  business,  planning  and  economic  and  commercial  control,  marketing  and  post-sale 

service of petrochemical products. 

Additionally, we also own a 50% interest in Profertil, a joint venture with Nutrien, a worldwide leader in fertilizers, which initiated operations in 2001. 
Profertil has a production facility in Bahía Blanca which produces 1.3 million tons of urea and 750,000 tons of ammonia per year. In addition, Profertil 
markets other nutrients and special blends of prepared land to optimize soil performance. 

Logistic Division 

Crude oil and products transportation and storage 

We have available for our use a network of five major pipelines, two of which are wholly-owned by us. The crude oil transportation network includes 
nearly 2,700 km of crude oil pipelines with approximately 640,000 barrels of aggregate daily transportation capacity of refined products. We have total 
crude oil tankage of approximately 7 mmbbl and maintain terminal facilities at five Argentine ports. 

Information with respect to YPF’s interests in its network of crude oil pipelines is set forth in the table below:

We own two crude oil pipelines in Argentina. One connects Puesto Hernández to the Luján de Cuyo refinery (528 km), and the other connects Puerto 
Rosales to the La Plata refinery (585 km) and extends to Shell’s refinery in Dock Sud at the Buenos Aires port (another 52 km). We also own a plant for 
the storage and distribution of crude oil in the northern province of Formosa with an operating capacity of 19,000 cm, and three tanks in the city of 
Berisso,  in  the  province  of  Buenos  Aires,  with  90,000  cm  of  capacity.  We  own  37%  of  Oleoductos  del  Valle  S.A.,  operator  of  an  888  km  pipeline 
network, its main pipeline being a double 513 km pipeline that connects the Neuquina basin and Puerto Rosales. 

We hold, through Oleoducto Transandino Argentina S.A. and Oleoducto Transandino Chile S.A., an interest of 36% and 18% respectively, in the 428 
km trans Andean pipeline, which transported crude oil from Argentina to Concepción in Chile. This pipeline ceased operating on December 29, 2005, as 
a consequence of the interruption of oil exports resulting from decreased production in the north of the province of Neuquén. The book value of the 
assets related to this pipeline was reduced to their recovery value. 

We  also  own  33.15%  of  Terminales  Marítimas  Patagónicas  S.A.,  operator  of  two  storage  and  port  facilities:  Caleta  Córdova  (province  of  Chubut), 
which has a capacity of 314,000 cm, and Caleta Olivia (province of Santa Cruz), which has a capacity of 246,000 cm. We also have a 30% interest in 
Oiltanking Ebytem S.A., operator of the maritime terminal of Puerto Rosales, which has a capacity of 480,000 cm, and of the crude oil pipeline that 
connects Brandsen (60,000 cm of storage capacity) to the Axion Energy Argentina S.R.L. (previously ESSO, a former subsidiary of ExxonMobil which 
was acquired by Bridas Corporation) refinery in Campana (168 km), in the province of Buenos Aires. 

In Argentina, we also operate a network of multiple pipelines for the transportation of refined products with a total length of 1,801 km. We also own 
seventeen storage terminals for distribution of refined products and seven LPG storage terminals with an approximate aggregate capacity of 1,620,000 
cm. Three of our storage and distribution terminals are annexed to the refineries of Luján de Cuyo, La Plata and Plaza Huincul. Ten of our storage and 
distribution terminals have maritime or river connections. We operate 52 airplane refueling facilities (40 of which are wholly-owned) with a capacity of 
22,500 mcm, 123 manual fuel dispensers and 17 automatic fuel dispensers. These facilities provide a flexible countrywide distribution system and allow 
us to facilitate exports to foreign markets, to the extent allowed pursuant to government regulations. Products are delivered by an exclusive tanker truck 
fleet of approximately 2,400 units of which 28 are owned. 

During the last year, after a national and international tender, and as the result of a bankruptcy process, YPF and Destilería Argentina de Petróleo 
S.A. (“DAPSA”) were awarded part of Oil Combustibles S.A. We acquired strategic assets that will be integrated to those already operated by YPF, 
especially the docks and fuel storage tanks located in the terminal located on the Paraná River that will allow us to expand the logistics capacity for 
future fuel exports, as well as for possible regional expansion. The network of Oil gas stations was acquired by DAPSA and Delta Patagonia S.A., as the 
result  of  the  bankruptcy  process  mentioned  before  and  an  agreement  with  YPF.  See  Note  3  to  the  Audited  Consolidated  Financial  Statements  for 
additional information. 

84 

As of December 31, 2018, our logistics processes remain certified under ISO 9001, ISO 1400l, OHSAS 1800l, and ISO 39001 Standards. 

Trading Division 

Our Trading Division trades refined products and crude oil to international customers and purchase crude oil from domestic oil companies. The 
refined products traded are unleaded gasoline, diesel, fuel oil, LPG, light naphtha, virgin naphtha, MTBE, green coke, decanted oil and AVGAS, among 
others. 

This  division  exports  to  different  countries,  principally  to  United  States  of  America,  Africa  and  Brazil,  as  well  as  to  other  countries.  Sales  to 
international customers for 2018 and 2017 were Ps. 13,244 million and Ps. 4,982 million, respectively. In 2018, refined products accounted for 53% of 
total sales, up from 49% in 2017. In 2018, 33% of total sales corresponded to marine fuels, down from 48% in 2017. In 2018 and 2017, sales volumes to 
customers outside Argentina consisted of 5.3 mmbbl and 3.0 mmbbl of refined products, respectively, and 2.0 mmbbl and 2.3 mmbbl of marine fuels, 
respectively. 

For the domestic market, sales of crude oil totaled Ps. 2,073 million, or 1.1 mmbbl, in 2018 and Ps. 995 million, or 1.2 mmbbl, in 2017. Sales of 

marine fuels totaled Ps. 3,025 million, or 1.2 mmbbl, in 2018 and Ps. 1,726 million, or 1.2 mmbbl in 2017. 

In addition, imports of low sulfur diesel, gasoline, alkylate and AVGAS in 2018 totaled 6.9 mmbbl, an increase of 49% compared with 4.6 mmbbl 

in 2017. The United States of America and Brazil were the principal origin of these imports. 

Imports of fertilizers, agrochemicals and paraffin totaled 0.24 million tons in 2018, growing 47% compared with 0.16 million tons in 2017. China 

and Morocco were the principal origin of fertilizer imports. 

In 2018, it was not necessary to import crude oil. 

Gas and Power 

During 2018,  our  Gas  and  Power  activities  included:  (i) the commercialization and  distribution  of  natural  gas  to  third  parties; (ii) the  technical 
operation of LNG regasification in Bahía Blanca (until October 31, 2018) and Escobar terminals, through the contracting of two regasification vessels; 
and (iii) the generation of both conventional thermal electricity and renewable energy projects mainly developed by YPF Energía Eléctrica S. A.

Delivery commitments 

We are  committed  to providing fixed  and  determinable  quantities of  crude oil and natural gas  in  the near future  under  a  variety  of contractual 

arrangements. 

With  respect  to  crude  oil,  we  sell  substantially  all  of  our  Argentine  production  to  our  Refining  and  Marketing  business  segment  to  satisfy  our 
refining requirements. As of December 31, 2018, we were not contractually committed to deliver material quantities of crude oil to third parties in the 
future. 

85 

As of December 31, 2018, we were contractually committed to deliver 15.3 mmcm (or 539 bcf) of natural gas in the future, (without considering 
interruptible export supply contracts) of which approximately 8.8 mmcm (or 311 bcf) will have to be delivered from 2019 through 2021. According to 
our estimates as of December 31, 2018, our contractual delivery commitments for the next three years could be met with our own production and, if 
necessary, with purchases from third parties. 

However,  since  2004  the  Argentine  government  has  established  regulations  for  both  the  export  and  domestic  natural  gas  markets  which  have 
affected  Argentine  producers’  ability  to  export  natural  gas.  Consequently,  since  2004  we  have  been  forced  in  many  instances  to  partially  or  fully 
suspend natural gas export deliveries that are contemplated by our contracts with export customers. On August 2018, the Ministry of Energy and Mining 
(predecessor  to  the  SGE)  (“MINEM”)  issued  Resolution  No. 104/2018  which  allows  local  producers  to  export  to  Chile  natural  gas  under  new 
procedures. See “Item 4. Legal and Regulatory Framework and Relationship with the Argentine Government—Market Regulation—Natural gas.” 

For information regarding regulations that have been affecting our operations see “Item 4. Information on the Company—Regulatory Framework 

and Relationship with the Argentine Government—Market Regulation.” 

For information regarding claims arising from restrictions in the natural gas market see “Item 8. Financial Information—Legal Proceedings.” 

On  November 29,  2017,  natural  gas  producers  (among  them,  YPF)  and  ENARSA,  at  the  request  of  the  MINEM,  subscribed  the  Terms  and 

Conditions. 

The  Terms  and  Conditions  set  forth  the  basic  policies  to guarantee  the  adequate  supply  of  natural  gas  to  Distributors,  and  consequently  to  the 
residential  and  commercial  final  consumers,  the  continuity  of  the  gradual  and  progressive  reduction  of  subsidies.  The  Terms  and  Conditions  were 
entered  into  within  the  framework  of  the  normalization  process  of  the  natural  gas  market,  which  provides  that  the  Terms  and  Conditions  will  be 
effective during the “transition period” to normalization which is currently scheduled to run through December 31, 2019. 

Among  other  provisions,  the  Terms  and  Conditions  recognize  the  right  to  transfer  the  cost  of  acquiring  gas  to  the  tariff  paid  by  users  and 
consumers and establish the volume that each producer and each basin must make available on a daily basis to the distributors (who in turn may express 
their lack of interest in receiving such amounts before a certain cut-off date set forth in the Terms and Conditions) during each month. In addition, the 
Terms and Conditions: (i) set forth penalties for any party’s non-compliance with their obligation to take or deliver gas, (ii) set maximum gas prices in 
U.S.  dollars  for  each  basin  for  the  two-year  period  from  the  execution  of  the  Terms  and  Conditions,  which  were  significantly  higher  than  those 
prevailing  until  this  agreement,  (iii) include  payment  guidelines  for  the  purchases  made  by  the  distributors  to  the  producers  and  (iv) they  include 
guidelines  for  early  termination  in  the  event  of  certain  breaches  by  the  parties.  Pursuant  to  the  Terms  and  Conditions,  during  the  transition  period 
ENARSA assumed the obligation to supply the demand corresponding to areas where the subsidies of residential gas consumption set forth in section 75 
of Law No. 25,565 (corresponding to the areas of lower price of residential gas charged to users and consumers) are applicable. 

The Terms and Conditions constitute guidelines for all parties in the negotiation of their respective individual agreements; however, the terms and 
conditions are guidelines and not obligations of the parties who entered into the Terms and Conditions. Entering the Terms and Conditions allows YPF 
to  have  predictability  over  its  demand  since  natural  gas  for  residential  consumers  is  no  longer  dispatched  according  to  priorities  established  in 
Resolution  No. 1410/2010  but  following  the  proportions  and  maximum  quantities  set  forth  in  the  Terms  and  Conditions  annexes,  compelling 
distribution companies to acquire natural gas for peak demand in the spot market. 

On  December 29,  2017,  MINEM  Resolution  No.  508-E/2017  was  published.  This  establishes  the  procedure  for  the  compensation  of  lower 
revenues  than  the  Licensees  of  the  Natural  Gas  Distribution  Service  for  User  Networks  See  “Item  4.  Information  on  the  Company—Legal  and 
Regulatory Framework and Relationship with the Argentine Government—Natural Gas.” 

During 2018, the natural gas market was deeply affected by the adverse situation of the Argentine economy and was also characterized by excess 
supply compared to domestic demand at certain times of the year, which impacted the production of natural gas resulting in the temporary closure of 
production in some locations, as well as in the reinjection of hydrocarbon. Based on this new scenario and new regulations (see “Item 4. Information on 
the  Company—Legal  and  Regulatory  Framework  and  Relationship  with  the  Argentine  Government—Natural  Gas—Tariffs.”)  and  agreements,  a 
reduction in natural gas sales prices in dollar terms, can be seen in relation to the prices stablished in 2017. 

See “Item 5. Operating and Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions” and “Seasonality.” 

86 

The devaluation of the Argentine Peso, among other impacts, triggered a renegotiation process of the agreements reached under the Terms and 
Conditions entered into on November 29, 2017 at request of the MINEM, to partially moderate the impact of passing through the effects of devaluation 
on  tariffs  to  end  users  while  keeping  the  contractual  relations  between  parties.  See  “Item  4.  Information  on  the  Company—Legal  and  Regulatory 
Framework and Relationship with the Argentine Government—Natural Gas—Tariffs.” 

This situation also caused the Local Distribution Companies (“LDC”) to incur debts with producers due to the difference between contractually 

agreed natural gas prices nominated in U.S.$ and the tariffs that LDCs charge to end users which are denominated in pesos. 

As natural gas prices were not passed to end users pursuant to the regulatory framework, the Argentine government issued Decree No. 1053/2018 
which set forth that differences caused by the variations in the exchange rate between natural gas prices and tariffs will be assumed by the Argentine 
Government.  Differences  and  interest  were  to  be  paid  in  30  installments  to  LDCs  beginning  in  October  2019,  and  thereafter  the  LDCs  must  make 
overdue  payments  to  producers.  Additionally,  LDCs  and  producers  agreed  to  waive  all  their  claims  relating  to  these  differences.  ENARGAS  is 
responsible  for  application  of  the  decree  and  its  regulation  is  still  pending.  See  “Item  4.  Information  on  the  Company—Legal  and  Regulatory 
Framework and Relationship with the Argentine Government—Natural Gas.” 

The above mentioned decree also set forth that from April 2019 onwards, differences generated as result of exchange rate variation shall not be 
passed through to final consumers. YPF is analyzing the potential courses of action available to it, in order to protect its rights and obligations under the 
law and the regulatory framework. See “Item 4. Risk Factors—Risks Relating to Our Business—We are exposed to the effects of fluctuations in the 
prices of oil, gas and refined products.” 

The natural gas market for power generation also suffered different changes: 

On August 1, 2018, the MINEM issued Resolution No. 46/2018 lowering natural gas price reference for electric generation by approximately 20% 
and  instructed  Compañía  Administradora  del  Mercado  Mayorista  Eléctrico  S.A.  (CAMMESA),  a  government-controlled  company,  in  charge  of  the 
electricity dispatch that concentrate the purchase of natural gas and fuels for power generation, to acquire combustibles through competitive processes. 

In  September  2018,  CAMMESA,  decided  to  purchase  most  of  the  natural  gas  to  be  consumed  between  September  and  December  through  an 
electronic bidding process. The bids were on a spot basis, not having either Take or Pay or Delivery or Pay obligations therefore there are not penalties 
for not delivering. Prices further decreased, but the process cannot be taken as a term firm price parameter as there were no obligations to deliver or to 
take the natural gas and the bidding conditions imposed a maximum price. 

On November 6, 2018, the SGE issued Resolution No. 70/2018 that gave back to power generators the ability to purchase their own natural gas 
supply.  Most of  the  power  generator  recovered the ability  to do  so,  therefore, prices  of natural  gas purchased  under  the bidding processes decreased 
further because of the competition for demand in the low consumption season and in an environment with oversupply and economic recession. 

At  the  end  of  December  2018,  the  government  decreased  again  the  natural  gas  price  reference  for  power  generation  by  between  16%  and  8% 
based  on  the  supply  basin  of  origin,  with  Neuquina  basin  being  the  most  affected.  Some  days  later,  CAMMESA  called  for  another  bidding  process 
under the same conditions. The term of this bidding was one year and again established maximum prices not related to free market pricing mechanisms. 
This bidding process resulted in even lower natural gas prices for generation. However, this cannot be considered a parameter due to the conditions of 
the bidding. 

Natural gas supply contracts 

The Argentine government has established regulations for both the international and domestic natural gas markets, which have affected the ability 

of producers in Argentina to export natural gas. Our principal supply contracts are briefly described below. 

We were committed to supplying a daily quantity of 125 mmcf/d (or 3.5 mmcm/d) to the Methanex plant in Cabo Negro, Punta Arenas, in Chile 
(under  three  original  agreements  entered  into  on  January 5,  1995,  March 11,  1997  and  November 13,  2001,  which  expire  between  2017  and 
2025). Pursuant  to  instructions  from  the  Argentine  government,  deliveries  have  been  interrupted  since  2007. In  connection  with  these  contracts,  the 
Company signed three new agreements with Methanex through which YPF eliminated all contractual obligations and past and future potential claims 
related to the original agreements through 2018. The first agreement was signed in 2011, through which YPF committed to investments in Upstream. 
The second one was signed in 2012, through which YPF committed to temporarily exporting gas to Chile and importing methanol as the final product 
(“Gas  Tolling  Agreement”),  receiving  the  approval  from  the  Argentine  government.  A  new  Gas  Tolling  Agreement  was  signed  in  December  2016, 
through which YPF committed to supplying a 

87 

total volume of 4 bcf (115 mmcm) of gas to Methanex through April 2018. The new Gas Tolling Agreement was signed by YPF and Methanex and 
presented for approval of the Argentine government to temporarily export gas and import methanol. An addendum to the Gas Tolling Agreement was 
signed on December 4, 2017 by YPF and Methanex, pursuant to which YPF has the option to supply 1 mmcm/d until September 2018 or until reaching 
a total amount of 115 mmcm whatever comes first. Each cubic meter delivered, reduces proportionally the commitment of YPF to deliver natural gas 
according  to  the  1997  Agreement,  from  January 1  to  December 31,  2019.  The  Gas  Tolling  Agreement  as  well  as  the  addendum  (both  approved  by 
MINEM through Resolution  No. 502/2017) states  that if the volumes of the addendum are  completely delivered, the commitment stablished in 1997 
Agreement,  is  considered  fulfilled.  However,  no  sanction  could  apply  to  YPF  if  the  company  decides  not  to  fulfill  the  volumes  mentioned  in  the 
addendum. During 2018, YPF delivered 113 mmcm of natural gas to Methanex fulfilling the agreement reached during 2017. Because of this operation 
and various renegotiations agreements with Methanex all contractual obligations and potential claims related to the original agreements entered into on 
January 5,  1995  and  March 11,  1997  and  the  contractual  obligations  and  potential  claims  through  2018  were  settled,  including  those  related  to  the 
agreement entered on November 13, 2001. 

Additionally,  in  November 23,  2018  Methanex  and  YPF  entered  into  an  agreement  to  suspend  through  December 31,  2019  the  contractual 
obligations  under  the  2001  agreement  and  establishing  contractual  conditions  for  deliveries  until  that  date  under  the  provisions  of  Resolution 
No. 104/2018, which was approved by SGE on March 6, 2019.We were engaged in a 15-year contract signed in 2003 with Gas Valpo, a natural gas 
distributor,  to  supply  35  mmcf/d  (or  1  mmcm/d)  through  the  Gas  Andes  pipeline  linking  Mendoza,  Argentina  to  Santiago,  Chile,  which  has  a 
transportation capacity of 353 mmcf/d (or 10 mmcf/d) (designed capacity with compression plants). As regulations changed, this contract was modified 
to an interruptible contract and subsequently terminated in 2018. 

We have a 21-year contract (entered into in 1999) to deliver 93 mmcf/d (or 2.63 mmcm/d) of natural gas to Innergy Soluciones Energéticas, a 
Chilean  distribution  company  that  distributes  natural  gas  to  residential  and  industrial  clients  through  a  natural  gas  pipeline  (with  a  capacity  of  318 
mmcf/d or 9 mmcm/d) connecting Loma La Lata in Neuquén, Argentina with Chile. The contract was modified to reduce its deliver or pay obligation, 
not to exceed an annual quantity of 20 mmcm with a daily basis of 7.1 mmcf/d (or 0.2 mmcm/d). 

In 2018, YPF renegotiated the 1999 Agreement with Innergy. The parties agreed to suspend the contract until both parties reach a new natural gas 

sales agreement. 

As a result of these negotiations, the parties entered into an interruptible agreement under the provisions of Resolution No. 104/2018 pursuant to 
which  YPF  will  deliver  to  Innergy  up  to  1.5  mmcm  of  natural  gas  per  day.  For  more  information,  see  “—  Legal  and  Regulatory  Framework  and 
Relationship with the Argentine Government—Natural gas export administration and domestic supply priorities.” 

Because of certain regulations implemented by the Argentine government, we could not meet our export commitments and were forced to declare 
force majeure under our natural gas export sales agreements, although certain counterparties have rejected our position. See “Item 4. Information on the 
Company—Exploration  and  Production—The  Argentine  natural  gas  market”  and  “Item  8.  Financial  Information—Legal  Proceedings.”  Because  of 
actions  taken  by  the  Argentine  government,  through  measures  described  in  greater  detail  under  “Item  4.  Information  on  the  Company—Legal  and 
Regulatory Framework and Relationship with the Argentine Government—Market Regulation—Natural gas,” during recent years we have been forced 
to reduce the export volumes authorized to be provided under the relevant agreements and permits. 

In August 2018, MINEM issued Resolution No. 104/2018 which established a new procedure to export natural gas under six different modalities 
and without the obligation to re-import the exported volumes. This resolution derogates Resolution No. 299/98 and its modifications and establishes that 
all the export permits, issued under the abovementioned resolution, must undergo the proceedings established under the new ruling and are subject and 
conditioned  to  the  security  of  local  market  supply.  Resolution  No  104/2018  also  derogates  Resolution  No. 265/2004,  Resolution  No. 883/2005  and 
Resolution No. 8/2017. See “Item 4. Legal and Regulatory Framework and Relationship with the Argentine Government—Market Regulation—Natural 
gas.” 

During 2018 YPF has entered into sales agreements with most of the main potential natural gas consumers from Chile (Colbún S. A., Gas VALPO 
S. A., Aprovisionadora Global de Combustibles S. A., ENEL Generación Chile S. A., Innergy Soluciones Energéticas S. A. and Methanex S. A.) and is 
currently  negotiating  with  other  potential  customers  from  that  country  and  Brazil.  Most  of  the  agreements  are  under  the  interruptible  alternative 
provided  in  Resolution  No.104/2018.  See  for  more  information  —  Legal  and  Regulatory  Framework  and  Relationship  with  the  Argentine 
Government— “Natural gas export administration and domestic supply priorities.”

The Argentine natural gas market 

We  estimate  (based  on  preliminary  reports  of  amounts  delivered  by  gas  transportation  companies)  that  natural  gas  consumption  in  Argentina 
totaled approximately 1,801 bcf (or 51.03 bcm) in 2018. We estimate that the number of users connected to distribution systems throughout Argentina 
was approximately 8.81 million as of October 31, 2018. 

In 2018, we sold approximately 28.5 % of our natural gas to local residential distribution companies, approximately 0.5 % to compressed natural 
gas end users, approximately 30.5 % to industrial users (including our affiliates, Mega and Profertil), approximately 32.7 % to power plants and 7.8 % 
to YPF downstream operations. Sales were affected by increased consumption by residential consumers during winter months (June to August). During 
2018, approximately 80% of our natural gas sales proceeded from the Neuquina basin. 

During  the  past  few  years,  the  Argentine  government  has  taken  many  steps  aimed  to  satisfy  domestic  natural  gas  demand,  including  pricing, 
export regulations, higher export taxes and domestic market injection requirements. These regulations were applied to all Argentine producers, affecting 
natural  gas  production  and  exports  from  every  producing  basin.  See  “Item  4.  Information  on  the  Company—Exploration  and  Production—Delivery 
commitments—Natural gas supply contracts.” Argentine producers such as YPF complied with the Argentine government’s directions to curtail exports 
to  supply  gas to  the  domestic  market,  whether  such  directions are issued  pursuant to  resolutions  or otherwise.  Resolutions  adopted  by  the  Argentine 
government provide penalties for non-compliance. Rule SSC No. 27/2004 issued by the Undersecretary of Fuels (“Rule 27”), for example, punishes the 
violation  of  any  order  issued  thereunder  by  suspending  or  revoking  the  production  concession.  Resolutions  No. 659  and  No. 752  also  provide  that 
producers not complying with injection orders will have their concessions and export permits suspended or revoked and state that pipeline operators are 
prohibited from shipping any natural gas injected by a non-complying exporting producer. 

The Argentine government began suspending natural gas export permits pursuant to Rule 27 in April 2004, and in June 2004 the Argentine government 
began issuing injection orders to us under Resolution No. 659. Thereafter, the volumes of natural gas required to be provided to the domestic market 
under  the  different  mechanisms  described  above  have  continued  to  increase  substantially.  See  additionally  “Item  4.  Information  on  the 
Company—Legal  and  Regulatory  Framework  and  Relationship  with  the  Argentine  Government—Natural  gas  export  administration  and  domestic 
supply priorities.” 

On January 8, 2017, Law No. 26,732, which establishes export duties on hydrocarbon exports, ceased to be in force. As a result, export duties are no 
longer imposed on natural gas exports. 

See  “Item  4.  Information  on  the  Company—Legal  and  Regulatory  Framework  and  Relationship  with  the  Argentine  Government—Natural  gas”  for 
additional information on these and other related regulations. 

Argentine natural gas supplies 

Most of our proved natural gas reserves in Argentina (approximately 75% as of December 31, 2018) are situated in the Neuquina basin, which is 
strategically  located  in  relation  to  the  principal  market  of  Buenos  Aires  and  is  supported  by  sufficient  pipeline  capacity  during  most  of  the  year. 
Accordingly, we believe that natural gas from this region has a competitive advantage compared to natural gas from other regions. The capacity of the 
natural gas pipelines in Argentina has proven in the past to be inadequate at times to meet peak-day winter demand, and there is no meaningful storage 
capacity in Argentina. Since privatization, local pipeline companies have added capacity, improving their ability to satisfy peak-day winter demand, but 
no assurances can be given that this additional capacity will be sufficient to meet demand. 

In order to bridge the gap between supply and demand, especially with respect to peak-day winter demand, the Argentine government has entered 

into gas import agreements. 

YPF has provided regasification services to IEASA (formerly ENARSA) under certain agreements since May 2008. The agreement between the 
parties required YPF to provide a regasification vessel moored in a jetty belonging to Compañía MEGA, S.A. in Bahía Blanca. Such agreement has been 
further extended and renegotiated to last until October 31, 2018 date on which the agreement has ended and the regasification vessel left the jetty. 

Since the beginning of its operations, this regasification vessel has converted 23.54 bcm (or 831.18 bcf) of LNG into natural gas, which has been 
injected into a pipeline which feeds the Argentine national network. Most of this volume was supplied during the peak winter demand period. In 2018, 
until completion of the contract on October 31, 2018 natural gas injected into the network amounted to approximately 1.69 bcm (or 59.5 bcf). 

89 

In addition to regasification activities, YPF is the operator of UTE Escobar (a joint venture formed by YPF and IEASA, which operates an LNG 
Regasification  Terminal  (“LNG  Escobar”)  located  in  Escobar  at  km  74.5  of  the  Paraná  River  in  the  province  of  Buenos  Aires.  UTE  Escobar  has 
executed agreements with Excelerate Energy to provide and operate a 151 mcm (or 533 mcf) regasification vessel moored at the LNG Escobar terminal 
with the capacity to supply up to 20 mmcm/d (or 700 mmcf/d) of natural gas. 

During 2018, UTE Escobar worked with Excelerate Energy towards increasing the regasification capacity. 

Since the beginning of its operations, this regasification vessel has converted 18.35 bcm (or 647.4 bcf) of LNG into natural gas, which has been 

injected into the Argentine network. In 2018, natural gas injected into the network amounted to approximately 1.85 bcm (or 65.3 bcf). 

During 2018, YPF entered into two agreements: a charter agreement for a liquefaction barge, which will be named “Tango FLNG”, with Exmar 
Energy Netherlands B.V. (“Exmar”); and a liquefaction services agreement with Exmar Energy Services B.V. (both companies are affiliated with Exmar 
N.V.). The agreements have a term of 10 years, with an investment by YPF of up to approximately U.S.$ 20 million. 

Through these agreements, YPF will be able to produce an approximate volume of 500,000 tons per year of LNG by taking natural gas from its 
deposits throughout the country. It will allow YPF to export this natural resource to different international markets, including Asia, Europe and regional 
markets. This is the first floating LNG export project in Latin America, the third in the world, which will make Argentina part of the select group of 
LNG exporting countries. The barge has a storage capacity of 16,100 m3 LNG and liquefaction capacity of 2.5 mm3/d of natural gas. 

The Tango FLNG is the first barge of its kind, it will operate in Bahía Blanca and is expected to begin operations during the second quarter of 

2019. 

Natural gas transportation and storage capacity 

Natural gas is delivered by us through our own gathering systems to the five trunk lines operated by Transportadora de Gas del Norte S.A and 
Transportadora de Gas del Sur S.A. from each of the major basins. The capacity of the natural gas transportation pipelines in Argentina is mainly used 
by  distribution  companies.  A  major  portion  of  the  available  capacity  of  the  transportation  pipelines  is  booked  by  firm  customers,  mainly  during  the 
winter, leaving capacity available for interruptible customers to varying extents throughout the rest of the year. 

We  have  utilized  natural  underground  structures  located  close  to  consuming  markets  as  underground  natural  gas  storage  facilities,  with  the 
objective  of  storing  limited  volumes  of  natural  gas  during  periods  of  low  demand  and  selling  such  natural  gas  during  periods  of  high  demand.  Our 
principal  gas  storage  facility,  “Diadema,”  is  located  in  the  Patagonia  region,  near  Comodoro  Rivadavia  city.  The  injection  of  natural  gas  into  the 
reservoir started in January 2001. 

Other investments and activities 

NGLs 

YPF participated in the development of its affiliate Compañía Mega S.A. (“MEGA”) to increase its ability to separate liquid petroleum products 

from natural gas. 

YPF owns 38% of MEGA, while Petrobras and Dow Chemical have stakes of 34% and 28%, respectively. 

MEGA operates: 

•

•

•

•

A separation plant, which is located in the Loma La Lata field, in the province of Neuquén. 

An NGL fractionation plant, which produces ethane, propane, butane and natural gasoline and is in the city of Bahía Blanca in the province 
of Buenos Aires. 

A pipeline that links both plants and that transports NGLs. 

Transportation, storage and port facilities near the fractionation plant. 

90 

MEGA’s maximum annual production capacity is 1.62 million tons of natural gasoline, LPG and ethane. YPF is MEGA’s main supplier of natural 
gas. The production of the fractionation plant is used in the petrochemical operations of PBBPolisur, S.A. (“PBB”), owned by Dow Chemical Company, 
and exported by tanker to Petrobras and other relevant clients. 

Pursuant  to  Decree  No. 2067/08  and  Resolutions  No. 1982/2011  and  1991/2011  of  ENARGAS,  since  December 1,  2011,  MEGA  had  been 
required to pay, monthly, a fee of Ps. 0.405 per cubic meter of natural gas it purchases. This requirement had a significant impact on the operations of 
Mega and was challenged in the Argentine federal courts. On October 27, 2015, the Argentine Supreme Court ruled on the legal proceedings filed by 
Mega covering the period up to the issuance of Law No. 26,784 (November 13, 2012). It ruled that Decree No. 2067/08 was unconstitutional and did not 
apply to Mega. 

In addition, on February 25, 2013, MEGA filed another action requesting that the federal courts declare the unconstitutionality of Articles 53 and 

54 of Law No. 26,784, which included within the provisions of Law No. 26,095 the fee created by Decree No. 2067/08 and ENARGAS regulations. 

On April 1, 2016, the Argentine Government issued Resolution No. 28, which provided for the suspension of the application of the fee created by 

Decree No. 2067/08 and related ENARGAS regulations effective as of the date of issuance. 

On  April 25,  2018,  a  federal  lower  court  ruled  that  Articles  53  and  54  of  Law  No. 26,784  were  unconstitutional  and  were  not  applicable  to 
MEGA.  The  Argentine  Government  appealed  such  decision  before  the  Federal  Chamber  of  Appeals  but  later  withdrew  the  appeal.  Thereafter,  the 
Federal Chamber issued a resolution confirming the Argentine Government’s withdrawal of the appeal and, consequently, the April 25, 2018 ruling was 
upheld. Therefore, this conflict has been definitively resolved in favor of MEGA. 

Electricity market—generation 

The Argentine Electricity Market 

Argentina’s  energy  demand  in  2018  was  almost like  its energy demand  in  2017,  only increased  0.3%  according  to  CAMMESA.  During  2018, 

domestic consumption increased 1.8% and exports increased more than 405%. 

To  satisfy  this  energy  demand,  Argentina’s  overall  power  generation  in  2018  was  0.75%  greater  than  power  generation  in  2017,  according  to 
CAMMESA.  In  2018,  63.8%  of  Argentina’s  power  generation  came  from  thermal  power  plants,  29.1%  from  hydroelectric  power  plants,  4.7%  from 
nuclear power plants, 2.4% from renewable energy sources and 0.25% from spot imports from Uruguay, Brazil, Paraguay and Chile (343.5 Gwh). Those 
spot imports were used to satisfy peak demand hours without capacity reserves and non-used wind energy from Uruguay. 

Peak capacity demand reached its maximum in February 2018 (26,320 Mw), but maintaining 1,895 Mw of capacity reserve for security of the 

electrical system. 

Thermal power plants consumed 874,773 mmcm of diesel oil, a decrease of 37.4% compared to 2017, 565,022 tons of fuel oil, a 56.1% decrease 

compared to 2017, and 18.03 bcm of natural gas, an 5.3% increase compared to 2017. 

The average electricity price was Ps. 2,117.5/MWh, an 80.4% increase compared to 2017, while the annual average marginal cost of production 
was Ps. 1,996/MWh, also a 35.49% increase compared to 2017 due to an improvement in the efficiency of power plants and to a lower consumption of 
liquid fuels. 

In 2017, Resolution No. 19/2017 of the Secretariat of Electric Energy replaced Resolution No. 95/13 and defined a new remuneration method for 
available power and generated energy, allowed the power generation plants to increase the profitability and reliability of the generation of energy. This 
resolution established remuneration based on the available power by type of technology (gas turbine, steam turbine, combined cycles, hydroelectric) and 
remuneration  for energy generated  and  operated. Likewise,  additional remuneration  was established as  incentive to efficiency.  The  payment  of these 
concepts is done in cash and denominated in dollars. This resolution remained in force during 2018. 

In Resolution SEE 287 - E / 2017 of May 10, 2017, the Ministry of Energy instructed CAMMESA to call interested parties to offer new thermal 
generation of technology: a) combined cycle or b) cogeneration, with compromise to be available to meet the demand in the wholesale electric market, 
contribute to the reduction of costs and to the increase of the reliability in the Argentine Electrical System. 

91 

On March 1, 2019, Resolution No. 1/2019 of the Secretary of Renewable Resources and Electric Market which derogated Resolution No. 19/2017 
of  the  former  Secretary  of  Electric  Energy,  effective  as  of  March 1,  2019,  and  among  other  aspects  provided  for  new  mechanisms  for  payment  of 
guaranteed  power  availability  and  generation  by  Generators,  Co-generators  and  Self-generators  from  MEM  (excluding  binational  hydroelectric 
generators,  nuclear  generators  and  Generators,  Co-generators  and  Self-generators  from  MEM  whose  generating  units  had  been  committed  as  part  of 
agreements for purposes of supplying the MEM from such regime). The prices for power and generation during the six months during which electric 
demand  is  lower  which  were  approved  by  Resolution  No. 1/2019  are  approximately  20%  lower  in  dollar  terms  than  those  set  forth  in  Resolution 
No. 19/2017. 

YPF in Power Generation 

On  August 1,  2013,  because  of  the  spinoff  of  the  assets  of  PlusPetrol  Energy  S.A.,  YPF  Energía  Eléctrica  S.A  (“YPF  EE”),  was  created  to 

continue the power generation operations and businesses of Central Térmica Tucumán and Central Térmica San Miguel de Tucumán. 

During 2018, YPF EE participated in the following power generation plants with an aggregate net installed capacity of 1,819 MW: 

•

•

•

•

•

•

•

•

•

a 100% interest in Central Térmica Tucumán (447 MW combined cycle) through YPF EE, in which we have a 100% interest; 

a 100% interest in Central Térmica San Miguel de Tucumán (382 MW combined cycle) through YPF EE, in which we have a 100% 
interest; and 

a 100% interest in Loma Campana Este (17 MW motogenerators) through YPF EE, in which we have 100% interest; 

a 100% interest in Loma Campana I (105 MW gas turbine) through YPF EE, in which we have a 100% interest; 

a 100% interest in La Plata Cogeneración (128 MW gas turbine) through YPF EE, in which we have a 100% interest; 

a 100% interest in Manantiales Behr (99 MW gas turbine) through YPF EE, in which we have a 100% interest; 

a 100% interest in Loma Campana II (107 MW gas turbine) through YGEN, in which we have a 100% interest; 

a 100% interest in El Bracho (267 MW gas turbine) through YGEN II, in which we have a 100% interest; 

a 30% interest in Central Dock Sud (797.5 MW combined cycle and 72 MW gas turbines), directly and through Inversora Dock Sud 
S.A., in which we have a 30% interest. 

Additionally, YPF EE owns assets that are part of Filo Morado Partnership, which has an installed capacity of 63 MW. However, the relevant 

facilities have not been in operation since November 2008. 

In addition to YPF EE, YPF also owns and operates power plants supplied with natural gas produced by itself, which produce power to supply 

upstream and downstream activities: 

•

•

•

Los Perales power plant (74 MW), which is in the Los Perales natural gas field; 

Chihuido de la Sierra Negra Power Plant (40 MW); and 

Plaza Huincul Power Plant (40 MW). 

In 2018, YPF EE generated 5,247 GWh with its two combined cycle plants. Central Térmica Tucuman’s production was 3,031 GWh, and Central 
Térmica  San  Miguel  de  Tucumán’s  production  was  2,216  Gwh.  Additionally, Central  Dock Sud  generated 1,215  GWh  considering  YPF  EE’s  stake. 
Energy produced by both combined cycle plants in Tucumán was 0.9% lower in 2018 compared to 2017. Also, the energy produced by Central Dock 
Sud in 2018 decreased by 20.11%. Throughout August there was a failure in the DSUDTG09 compressor’s fixed parts which caused important damage 
both in the compressor itself as well as in the vanes of the gas turbine. The turbine resumed its operation in December 2018. 

On  November 7,  2017,  YPF  EE  reached  the  commercial  operating  date  of  an  important  new  thermal  power  generation  plant,  Central  Térmica 
Loma  Campana  (105  MW  gas  turbine),  which  is  in  Añelo,  Neuquén.  This  additional  generation  plant  was  designed  with  the  objective  of  supplying 
YPF’s internal energy demand all over the country. In 2018 this power plant generated 432 Gwh. Throughout February there was a booster stall in the 
gas turbine LCAMTG01 that caused the failure in the compressor’s fixed and mobile parts, leading to the subsequent replacement of the compressor. 
Such failure lasted for approximately 20 days. Also, throughout the months of February and March a failure in the cooling system of the gas turbine 
LCAMTG02 due to low flow appeared, causing the subsequent redesign of the cooling towers. Such failure lasted for approximately 40 days. 

92 

At the beginning of 2018 YPF EE bought the cogeneration plant in La Plata from Central Puerto S.A (128 MW), which generated 874 Gwh in 

2018. 

Within the framework of Secretary of Electrical Energy (S.E.E.) Resolution No. 21/2016, YPF EE, together with a subsidiary of General Electric, 

decided to engage in two projects for the development and operation of two power plants. 

One  project  consists  of  a  new  107  MW  thermal  power  plant  located  at  Loma  Campana  in  Neuquén  Province,  Argentina.  The  project  has 
succeeded in obtaining a purchase price agreement at the second round of the power capacity auction established through S.E.E. Resolution No. 21/2016 
and the reference terms issued by CAMMESA. The commercial operating date of this power plant was on November 30, 2017, generating 395 GWh 
during 2018. 

The  second  project  consists  of  a  new  267  MW  thermal  power  plant  located  at  El  Bracho  in  Tucumán  Province,  Argentina.  The  project  has 
succeeded in obtaining a purchase price agreement at the first round of the power capacity auction established through S.E.E. Resolution No. 21/2016 
and the reference terms issued by CAMMESA. The project reached the commercial operating date on January 27, 2018, generating 545 GWh during 
that year. 

Both  projects  involved  an  aggregate  investment  of  U.S.$  307.9 million,  and  the  total  shareholders’  contribution  was  U.S.$  88.4 million 
(approximately  U.S.$  58.9 million  payable  by  YPF  EE),  with  the  remainder  of  the  investment  amount,  U.S.$  219.5 million  financed  by  financial 
institutions. 

Additionally, in order to, to support YPF’s operations, YPF EE owns Loma Campana East, which consists of 12 Jenbacher engines financed by a 
bank lease from Supervielle bank. It is located in Añelo, Province of Neuquén, and built on land owned by YPF. During 2018, these engines generated 
34 GWh. 

As a consequence of Law No. 27,191 related to renewable energy, YPF EE started in 2016 the construction of its renewable generation project, 
Manantiales Behr Wind Farm (99 MW), near Comodoro Rivadavia in the Chubut province, in order to supply the percentage of YPF total demand with 
clean  generation  that  will  be  required  by  law  in  2018.  This  project  reached  the  commercial  operating  date  of  the  first  46.2  MW  on  July 24,  2018, 
completing on December 24, 2018, generating 150 GWh during this period. 

The energy produced by YPF EE and Central Dock Sud (8,891 GWh in total, considering YPF EE’s stake in Central Dock Sud) represented 6.5% 

of Argentina’s electricity generation in 2018. 

In addition, pursuant to Law No. 27,191, the Ministry of Energy and Mining launched in August 2017 the Plan RenovAr 2.0, an auction for 1,200 
MW for the construction of renewable energy generation plants, in which YPF EE was awarded with the construction of the Cañadón Leon Wind Farm, 
a project of another 99 MW of clean generation, in the Santa Cruz province. Under the terms of the auction, this project will allow YPF EE to have 
another power purchase agreement with CAMMESA. This project is expected to be finished during the second quarter of 2020. 

As  far  as  efficient  energy  generation  is  concerned,  YPF  EE  won  the  award  of  two  projects  at  the  second  round  of  the  cycle  closure  and 
cogeneration plants auction established through S.E.E. Resolution No. 287/2017. One project consists of a new 72 MW cogeneration plant located in the 
Buenos Aires province. The other implies the closure of the open cycle of the El Bracho thermal power plant in Tucumán (198 MW). 

In addition, and pursuant to Resolution No. 281-E/2017, YPF EE was awarded dispatch priority for two additional renewable generation projects, 
Los Teros Wind Farm (122.6 MW) and Los Teros II Wind Farm (49.8 MW). These projects will allow YPF EE to commercialize renewable energy in 
the private market (Mercado a Término de Energías Renovables – “MATER”). Los Teros I is expected to be finished by the end of 2019 and Los Teros 
II during the second quarter of 2020. 

With  all  these  projects  in  its  portfolio,  among  others,  YPF  EE  pursues  to  be  one  of  the  strongest  competitors  in  the  electrical  generation  market  in 
Argentina. For this purpose, YPF EE established negotiations with GE Energy Financial Services during 2017 in order to redistribute its share capital, 
trusting that the entrance of the strategic partner will hasten the growth of the company in the country. 

93 

On  December 14,  2017,  the  Board  of  Directors  of  the  Company  approved  the  terms  of  a  memorandum  of  understanding  signed  with  GE  Energy 
Financial Services, Inc. (“GE EFS”) which established the framework conditions under which the parties would agree to the capitalization of YPF EE. 
This Agreement, established that GE EFS intended to contribute capital through a vehicle company and subscribe for shares of YPF EE in order to have 
a shareholding of 25% of its capital stock. 

On February 6, 2018, the conditions of the definitive and binding agreement entered into by YPF with EFS Global Energy B.V. (“GE”) and GE Capital 
Global Energy Investments B.V., companies indirectly controlled by GE EFS, which established the conditions for the capitalization of YPF EE (the 
“Share  Subscription  Agreement”).  The  Share  Subscription  Agreement  established  that  GE,  subject  to  compliance  with  certain  preceding  conditions, 
would subscribe for shares of YPF EE to have a shareholding of 24.99% of its capital stock and jointly control this company with YPF. 

The contribution would be U.S.$ 310 million, composed as follows: 

•

Subscription price of U.S.$ 275 million: 

•

•

U.S.$ 135 million as of the closing date of the transaction; and 

U.S.$ 140 million 12 months after the closing date of the transaction. 

•

Contingent price of up to the maximum sum of U.S.$ 35 million subject to the evolution of the prices of Resolution No. 19/17 (33.33% as of 
24 months from the closing date of the transaction and 16.67% each subsequent year). 

On  March 20,  2018,  GE,  a  subsidiary  of  EFS  Global  Energy  B.V.  (both  corporations  indirectly  controlled  by  GE  Energy  Financial  Services,  Inc.), 
subscribed  for  shares  of  YPF  EE  in  an  amount  equal  to  24.99%  of  YPF  EE’s  capital  stock  through  a  cash  contribution  of  U.S.$  275 million,  plus  a 
contingent payment for up to U.S.$ 35 million. This cash contribution will allow YPF EE a more accelerated development of its business plan. As of the 
date of the subscription of YPF EE shares by GE, GE and YPF have joint control of YPF EE. 

See Note 3 to the Audited Consolidated Financial Statements for additional information. 

Natural gas distribution 

We currently hold a 70% stake in Metrogas S.A. (“Metrogas”), a natural gas distribution company in the capital region and southern suburbs of 
Buenos Aires, and one of the main distributors in Argentina. During 2018, Metrogas distributed approximately 20.8 mmcm (or 733.4 mmcf) of natural 
gas per day to 2.4 million customers in comparison to approximately 20.4 mmcm (or 719.7 mmcf) of natural gas per day to 2.4 million customers in 
2017.  During  May  2013,  we,  through  our  subsidiary  YPF  Inversora  Energética  S.A.  (“YPF  Inversora  Energética”),  gained  100%  ownership  of  Gas 
Argentino S.A. (“GASA”), the controlling company of Metrogas, by acquiring shares representing the remaining 54.7% interest in GASA not already 
owned by us. In 2016, GASA and YPF Inversora Energética were both merged into us and dissolved without liquidation. 

Additionally, on December 28, 2016, YPF has received from Metrogas a copy of the note received by it from ENARGAS, requesting it to adjust 
Metrogas’ equity structure in line with the term provided for in Emergency Law No. 25,561 and in compliance with Section 34 of Law 24,076. In this 
regard, it should be noted that YPF indirectly acquired 70% of Metrogas’ equity, which transaction was approved by ENARGAS Resolution No. I/2,566 
dated April 19, 2013; and, following the merger with YPF Inversora Energética S.A. and Gas Argentino S.A., is the holder of 70% of Metrogas shares. 

On  March 30,  2017,  YPF  filed  an  appeal  for  reconsideration  requesting  to  overrule  the  ENARGAS  Note  and  render  a  new  decision  setting  a 

reasonable timeframe consistent with the current reality of the gas market to comply with the provisions set forth article 34 of Law 24,076. 

On  June 15,  2017,  YPF  submitted  to  ENARGAS  a  tentative  schedule  for  the  process  of  adapting  its  equity  interests  in  Metrogas,  which  was 

expanded in detail on July 3, 2017. 

On April 5, 2018, ENARGAS rejected the reconsideration petition filed by YPF on March 30, 2017. Said decision was notified to YPF on April 6, 

2018, by means of ENARGAS Resolution No. 313/2018. 

YPF requested access to the proceedings, which was granted by ENARGAS on September 10, 2018, which in turn enabled the Company to file a 

timely appeal. 

94 

On October 8, 2018, YPF filed an appeal with the SGE. As of the date of this annual report, this appeal is pending resolution. 

Metrogas tariff issues 

The Emergency Law published in the Official Gazette on January 7, 2002, modified the legal framework in force for license contracts of public 

services. 

The  main  provisions  of  Emergency  Law  that  have  an  impact  on  the  License  duly  granted  to  MetroGAS  by  the  National  Government  and  that 
modified  express  provisions  of  the  Gas  Law  were  the  following:  “pesification”  of  tariffs  that  were  fixed  in  convertible  dollars  at  the  exchange  rate 
specified in the Convertibility Law (Law No. 23,928), the prohibition of tariff adjustments based on any foreign index, thus not allowing the application 
of  the  international  index  specified  in the  Regulatory  Framework  (US  Producer  Price  Index-PPI)  and  the  renegotiation  of  the  License  granted  to  the 
Company in 1992. 

Moreover,  the  Emergency  Law  established  the  beginning  of  a  renegotiation  process  of  public  utility  services  agreements  granted  by  the  PEN 

without detriment to the requirements that utility services companies must go on complying with all their obligations. 

The  Emergency  Law,  which  was  originally  to  be  due  in  December  2003,  was  extended  several  times  until  December 31,  2017.  The  terms  for 
renegotiating  licenses  and  public  services  concessions  were  also  extended.  See  “Item  4.  Information  on  the  Company—Legal  and  Regulatory 
Framework and Relationship with the Argentine Government— Public Emergency.” In the framework of the renegotiation process, the Company signed 
a series of agreements with different entities representing the National Government. 

For the agreements signed in 2017 and 2018, see “Item 4. Information on the Company—Legal and Regulatory Framework and Relationship with 

the Argentine Government—Natural Gas—Tariffs.” 

Seasonality 

For  a  description  of  the  seasonality  of  our  business,  see  “Item  5.  Operating  and  Financial  Review  and  Prospects—Factors  Affecting  Our 

Operations—Seasonality.” 

Research and Development 

At  the  end  of  2013,  YPF  created  YPF  Tecnologia  S.A.  (“Y-TEC”),  a  highly  specialized  company  focusing  on  research  and  development  (“R&D”) 
activities. YPF holds an interest stake of 51% and CONICET, a state-owned research and development organization, holds an equity interest of 49%. 

All lines of R&D carried out by Y-TEC are strategically aligned with the needs of YPF. The Board of Directors of Y-TEC consists of three directors 
appointed by YPF and two directors appointed by CONICET; additionally, the Chairman and the General Manager of Y-TEC are appointed by YPF. 

For the operations of Y-TEC, five hectares from the National University of La Plata (“UNLP”) were acquired, and a 13,000 m2 building consisting of 
47  labs  and  12  experimental  plants  was  recently  built.  The  staff  and  the  equipment  moved  into  the  new  building  in  June  2016.  More  than  300 
professionals work in the new building creating innovative solutions for the energy sector. 

The main goals of Y-TEC are: to generate high-impact technological solutions, provide high quality technical and laboratory support services and lead 
the fast implementation in the industry of existing innovative technologies. 

Y-TEC explores opportunities throughout the actual and future energy sector. This is a broad and diversified strategy approach that covers core areas 
such as Unconventional Resources, Mature Fields and Petrochemical, as well as New Energies, Future Mobility and Environmental Sustainability. 

The new R&D portfolio consists of 51 projects and more than 100 technical assistance and specialized services. 

In 2018, U.S.$23.7 million was allocated to R&D activities, and U.S.$0.56 million (YPF’s working interest) was invested in new equipment. 

95 

Y-TEC believes in the value of liaising with technological partners to reinforce regional leadership, adopting the open innovation concept. This concept 
allows us to reduce technological risk, shorten the time to have the product on the market and minimize costs. 

Since 2016, we have opened more than twenty “Innovation Spaces.” These are areas promoted by Y-TEC to complement scientific capacities in public 
and private institutions and allow the development of high impact technological products for the national energy industry. Knowledge, experience and 
state-of-the-art equipment are brought together by Y-TEC and CONICET. 

In exploration and production of unconventional resources, R&D efforts are focused on reducing the development field cost, by the design, development 
and application of very specific technologies. Our most important challenges include simulation and modeling tools design and development, measuring 
and monitoring solutions, tailored made fluids and smart proppants, additives and chemical products for optimizing drilling, completion and production 
operations. 

To optimize production from mature fields, we focused on increasing the recovery factor by the development of enhanced oil recovery technologies and 
the development of new processes and materials to reduce the operational costs of our facilities, to increase their run life and integrity. 

Regarding oil products refining and marketing, we applied our technological knowledge to optimize refinery operations and improve product quality, 
with a strong focus on the achievement of energy efficiency and environmental improvements. In the petrochemical business, R&D activities are mainly 
focused on the development of new products with higher added value, such as special solvents, fertilizers and several agricultural products. 

Renewable energy is a strategic R&D area. Energy storage based on li-ion technologies, solar energy (photovoltaics and thermal), hydrogen production, 
bioenergy and energy efficiency are among the greatest challenges. 

Supporting  the  process  of  transformation  initiated  by  YPF  and  in  line  with  the  advancement  of  digital  technologies,  we  created  in  Y-TEC  the  first 
Center of Excellence in Analytics (COE, fully dedicated to running data science projects across all YPF businesses. 

The COE combines, under one single department, data scientists, process modeling experts and IT professionals to provide integrated solutions to O&G 
industry. With this initiative, YPF is set at the forefront of other companies in the country by enhancing the use of the data to improve performance, 
protect assets and discover new businesses. The main goals of the COE are: to lead the company cultural revolution by making data analytics accessible 
to all levels of the organization; to promote a vision of “one team” overseeing synergies and the integration of different data science projects and to 
multiply value by prioritizing projects that can give the highest return on investment. 

Competition 

In our Upstream business, we encounter competition from major international oil companies and other domestic oil companies in acquiring exploration 
permits and production concessions. Our Upstream business may also encounter competition from oil and gas companies created and owned by certain 
Argentine  provinces,  including  La  Pampa,  Neuquén,  Santa  Cruz  and  Chubut.  See  “—Legal  and  Regulatory  Framework  and  Relationship  with  the 
Argentine  Government—Overview”  and  “—Legal  and  Regulatory  Framework  and  Relationship  with  the  Argentine  Government—Law  No. 26,197.” 
However,  changes  introduced  in  the  Hydrocarbons  Law  through  Law  No. 27,007  (2014)  limit  the  ability  of  provincial  companies  to  possess  future 
exclusive  rights  over  permits  and  concessions,  which  supports  competition  in  the  Argentine  oil  and  gas  industry.  See  “—Legal  and  Regulatory 
Framework  and  Relationship  with  the  Argentine  Government—Law  No. 27,007,  (amendment  of  the  Hydrocarbons  Law).”  Moreover,  during  the  last 
several years we have made a comprehensive move to secure, either by renewing, extending and converting through mechanisms provided in the Law, 
the majority of such permits and concessions in Argentina considered valuable in the long term. 

In our Downstream businesses, we face competition from domestic and international oil companies. In our export markets, we compete with numerous 
oil and trading companies. We operate in a dynamic market in the Argentine downstream industry and the crude oil and natural gas production industry. 
Crude oil and most refined products prices are subject to international supply and demand and, in certain cases, to Argentine regulations. 

See  “Item  3.  Key  Information—Risk  Factors—Risks  Relating  to  Our  Business—Limitations  on  local  pricing  in  Argentina  may  adversely  affect  our 
results of operations”, “Item 3. Key Information—Risk Factors—Risks Relating to Our Business— We are exposed to the effects of fluctuations in the 
prices  of  oil,  gas  and  refined  products”,  and  “Item  4.  Information  on  the  Company—Legal  and  Regulatory  Framework  and  Relationship  with  the 
Argentine Government—Natural Gas—Tariffs.” 

96 

We  continuously  assess  the  external  environment  and  our  competitive  position  to  adjust  our  business  strategies  and  plans  to  create  and  sustain 
competitive advantage. 

Environmental Matters 

YPF-Argentine operations 

YPF carries forward its mission to produce and provide energy focus on environmental care, trying to minimize the impact, looking enhance the positive 
effects associated with its work and prioritizing the protection of workers, the environment and the community in general. 

We reaffirmed that commitment on environmental management during 2018 through the approval of our Operational Excellence Policy which replaced 
and  upgraded  our  Environmental  Protection  and  Health  Preservation  Policy.  Environmental  management  is  built  upon  a  strong  corporate  culture  of 
security and protection, and it is deployed through a management system focused on occupational risks, the mitigation of industrial risks and integration 
of the principles of process safety to control the risks and the impacts. This management system and its application is certified according to standards 
OHSAS 18001 (Safety) and ISO 14001 (Environment) in the major industrial centers of the company. 

All the company’s segments are constantly upgrading their integrated management systems and major environmental parameters are subject to reporting 
and monitoring as a means to evaluate our performance and implement any necessary improvements. 

Our operations are subject to a wide range of laws and regulations relating to the general impact of industrial operations on the environment, including 
air emissions and waste water, the disposal or remediation of soil or water contaminated with hazardous or toxic waste, fuel specifications to address air 
emissions and the effect of the environment on health and safety. We have made and will continue to make expenditures and investments in order to 
warrant the reliability and integrity of our assets and operations and to comply with these laws and regulations as well. In Argentina, local, provincial 
and national authorities are moving towards more stringent enforcement of applicable laws. In addition, since 1997, Argentina has been implementing 
regulations that require our operations to meet stricter environmental standards that are comparable in many respects to those  in effect in the United 
States and in countries within the European Community. These regulations establish the general framework for environmental protection requirements, 
including the establishment of fines and criminal penalties for their violation. We have undertaken measures to achieve compliance with these standards 
and  are  undertaking  various  abatement  and  remediation  projects,  the  more  significant  of  which  are  discussed  below.  We  cannot  predict  what 
environmental legislation or regulation will be enacted in the future or how existing or future laws will be administered or enforced. Compliance with 
more stringent laws or regulations, as well as more vigorous enforcement policies of regulatory agencies, could require additional expenditures in the 
future  by  us,  including  the  installation  and  operation  of  systems  and  equipment  for  remedial  measures,  and  could  affect  our  operations  generally.  In 
addition, violations of these laws and regulations may result in the imposition of administrative or criminal fines or penalties and may lead to personal 
injury claims or other liabilities. 

Simultaneously,  we  have  in  place  comprehensive  risk  management  policies  in  connection  with  our  assets,  processes,  businesses  and  projects, 
integrating, at all stages of their life cycle, criteria and preventive actions for environmental protection, safety, health, quality, integrity and reliability. 
We  operate  not  only  in  strict  compliance  with  policies,  rules  and  procedures,  within  Argentina’s  current  legal  and  regulatory  framework,  but  also 
proactively adopting reference standards in the absence of legislation. 

As an example of our work towards best practices in the industry, we have implemented an investment plan aimed at improving the quality of fuels. 
Resolution No. 5/2016 of the Secretary of Hydrocarbon Resources set new specifications for sulfur content in fuels. In 2019 the first change in the sulfur 
content  in  gasoline  will  come  into  effect,  for  which  work  in  respect  of  the  gasoline  blending  process  in  the  La  Plata  Refinery  and  Luján  de  Cuyo 
Refinery is being conducted. This Resolution establishes that as of 2022 sulfur specifications will be adjusted for Degree 2 of Gasoil and Gasoline oil. 
Hence,  investments  are  being  made  since  2018  in  order  to  comply  with  these  new  specifications:  the  development  of  a  new  unit  of  coke  petrol 
hydrotreatment, the revamping of the magnaforming units and the FCC petrol hydrotreatment in La Plata Industrial Complex and the revamping of the 
hydrotreatment of petrol and a new gasoil desulphurizing unit in Luján de Cuyo Refinery. These units are expected to begin estimations by the end of 
2021. 

In  La  Plata  Industrial  Complex  an  ambitious  plan  of  effluents  adequacy  is  being  followed  since  2014,  including  drain  fluids  segregation  and  raft 
building which also allows us to strengthen the resilience of our facilities to the new climatic conditions of the region. Furthermore, connection works 
for the discharge of security torches are being completed according to the Resolution No. 231/96 of the Environmental Policies Office of Buenos Aires 
Province. 

97 

In Logistics, the integrity plan for tanks and pipelines is developed annually to ensure their tightness. 

Annually,  plans  are  developed  across  business  units  to  comply  with  different  Security  and  Environmental  Resolutions.  Works  based  on  Resolutions 
No. 785/05 and Resolution No. 404/94 are performed on tanks and inspections of pipes according to Resolution No. 1460/06 are carried out as well. 
Following regulations of the Buenos Aires Province’s Organization for Sustainable Development, we also do pressure container inspections. 

In  addition  to  the  projects  mentioned  above,  we  have  begun  to  implement  a  broad  range  of  environmental  projects  in  the  domestic  Exploration  and 
Production, Refining & Marketing and Chemicals segments, such as increasing the capacity of biological treatment in the La Plata refinery, a new flare 
in the Luján de Cuyo refinery, wastewater treatment and fire protection facilities, new flare in CIPH, improvement of fireproofing in existing facilities 
and implementation of bottom loading systems in terminals. 

We  and  several  other  industrial  companies  operating  in  the  La  Plata  area  have  entered  into  a  community  emergency  response  agreement  with  three 
municipalities and local hospitals, firefighters and other health and safety service providers to implement an emergency response program. This program 
is  intended  to  prevent  damages  and  losses  resulting  from  accidents  and  emergencies,  including  environmental  emergencies.  Similar  projects  and 
agreements were developed at other refineries and harbor terminals as well. During 2016, we implement a similar program in the Luján de Cuyo area. 

In 2018, an agreement was entered into with Oil Spill Response Ltd. enterprise to implement a plan with the purpose of evaluating and reducing the 
possible environmental impact caused by an oil spill in Argentine surface waters, thus reducing the environmental impact of potential oil spills offshore. 
This agreement includes technical and operational support in case of oil spills on rivers or seas caused by accidents involving cisterns or exploration and 
production offshore. 

During 1997 and 1998, each of our refineries (La Plata, Luján de Cuyo, and Plaza Huincul) were certified under the ISO (International Organization for 
Standardization)  9001  (quality  performance)  and  ISO  14001  (environmental  performance).  All  of  them  are  also  certified  under  the  OHSAS  18001 
(occupational  health  and  safety  performance)  standard.  In  addition,  since  2008,  the  La  Plata  and  Luján  de  Cuyo  complexes  have  been  verified  in 
accordance with ISO 14064 for the inventories of industrial greenhouse gases. The refineries maintain their systems under continuous improvement and 
revision by accredited organizations. 

Focusing  on  the  development  and  research,  the  company  created  YPF  Tecnología  S.A.  (see  “Item  4.  Information  on  the  Company—Research  and 
Development”) which is implementing an Environmental Sustainability Program focused on three strategic areas: reduction of emissions, increase of 
sustainable production and bioproduct development. This translates into high-impact projects for the industry, namely, effluent treatment, development 
of new production technologies, soil bioremediation, CO2 capture and valorization, atmospheric contaminant removal, and valorization of agricultural 
products and waste. With respect to climate change, over the next years we are committed to a lower carbon economy through more efficient oil, gas, 
fuels and derivatives production, lower intensity in GHG emissions, and cleaner electric power with a higher share of renewable energies. 

In this context, during 2018 we reaffirmed our Commitment on Climate Change and Energy Efficiency (which was developed in 2015 and renewed in 
2017) which provides the framework for working on mitigation and adaptation activities. The identified lines of action include the following: 

•

Integrate climate risk analysis methods; 

• Become the third electric power generator in the country in the future; 

• Encourage and boost energy efficiency by improving performance in our facilities and activities; 

• Advance research and development of new related technologies; 

• Achieve a reduction of our operations specific GHG emissions in near future. 

• Achieve the target of having approximately 70% of our vehicle fuels conform to low-sulphur standards (Euro V) in the near future. 

• Develop climate change adaptation strategies for our operations. 

Regarding this commitment, we continued working on: 

•

Improving Energy Efficiency. In 2017 we completed an energy assessment of production processes in the Company’s three main 
segments  (Upstream,  Downstream,  and  Gas  and  Power).  This  helped  us  ascertain  YPF’s  balance,  consolidated  and  area-specific 
consumption, establish a baseline, and identify energy efficiency opportunities. 

98 

This assessment will be carried out on completed, in-progress and planned projects. In the Downstream business, the most relevant 
projects are associated with cogeneration in the City of La Plata and revamping of units in La Plata and Luján de Cuyo industrial 
complexes, while in the upstream business, those related to electrification and generation improvements brought about by changes in 
equipment in mature oilfields. In Gas and Power, the key to energy efficiency lies in renewable energy projects, which will be the 
most significant contributors to reducing specific GHG emissions. 

As  part  of  this  process,  at  the  beginning  of  2018,  YPF  has  decided  to  upgrade  the  consumption  and  deficiency  logging  and 
monitoring system, and implement a coordinated, company-wide energy management system 

Monitoring our two projects registered under the Clean Development Mechanism (“CDM”), which allow us to reduce the emissions 
in the different stages and processes of crude oil refining through the recovery of flare gas in La Plata (CILP) and Luján de Cuyo 
(CILC)  industrial  complexes.  Residual  gases  are  compressed  and  injected  into  the  fuel  system  to  feed  furnaces  and  boilers,  thus 
avoiding  the  need  to  use  natural  gas  and  fuel  oil  for  heating.  In  2018,  CO2  was  reduced  by  around  172,909  tCO2  between  both 
projects. 

The  methodology  developed  by  YPF  was  approved  by  the  United  Nations  in  2007  under  the  name  of  AM0055  “Baseline  and 
Monitoring Methodology for the recovery and utilization of waste gas in refinery facilities”. To date, there are six projects registered 
under the CDM that have implemented this methodology around the world (Argentina, China, Kuwait and Egypt). 

Continuing  and  strengthening  Greenhouse  Emissions  (“GHG”)  Inventorying.  Since  2008  we  have  been  gradually  introducing 
management  systems into  our operations to record emissions through GHG inventories,  applying the ISO  14064-1  standard. This 
inventory has been successfully checked in the Ensenada Industrial Complex since 2008. During 2016, we began to implement the 
verification  of  greenhouse  gas  emissions  inventory  by  a  third  party  in  Plaza  Huincul  refinery.  During  2017,  we  completed  an 
external audit of all of YPF’s industrial complexes: La Plata (Refinery and Petrochemical Plant), Luján de Cuyo, and Plaza Huincul 
(Refinery and Methanol Plant). We also monitored other air emissions (SO2, NOx, CO, NMVOC, and particulate) in accordance 
with applicable regulations. 

The  forestry projects  located in the  province of  Neuquén which constitute approximately  7,000  hectares of  trees forested under  a 
long-term work program. Using the afforestation methodologies and tools available at the United Nations Framework Convention on 
Climate  Change  (“UNFCCC”)  Clean  Development  Mechanism  web  site,  it  was  possible  to  arrive  to  a  conservative  estimated 
amount  of  approximately  760,000  tons  of  CO2  equivalents  that  were  captured  by  the  afforestation  project  activities  from  1984 
(when the first afforestation activity occurred) through 2014; 

The  commitment  to  minimize  gas  sent  to  flares  and  gas  vented,  giving  compliance  to  the  requirements  established  in  National 
Resolutions  No. 236/93  and  No. 143/98  issued  by  the  former  Energy  Secretariat  of  the  Nation  (SEN)  and  all  those  applicable 
provincial  regulations.  In  this  sense,  there  is  a  new  initiative,  implemented  in  Mendoza:  the  virtual  gas  pipeline,  that  implies  the 
liquefaction and transportation of the natural gas associated from remote wells to an electric power plant in order to reduce flaring. 

Developing Electric Power and renewable energy business. See “Item 4. Information on the Company—Gas and Power.” 

Climate Change Adaptation: We moved forward with climate risk assessment projects at the Company’s facilities by implementing 
the  Business  Areas  Climate  Impact  Assessment  Tool  or  BACLIAT.  In  2017  we  also  used  it  at  the  Logistics  Terminal  located  in 
Concepción del Uruguay. We looked into past, current and future climate trends; detected primary risks; and identified mitigation 
actions to reduce vulnerability and encourage early action.

Strengthening  the  relationship  established  with  the  Argentinean  Environmental  Authority  (Ministerio  de  Ambiente  y  Desarrollo  Sustentable  de  la 
Nación), in particular with its Climate Change Unit (CCU - Dirección de Cambio Climático) in order to collaborate with the development of the Third 
National Communication on Climate Change to the UNFCCC and during 2017 in workshops organized by the CCU for developing the National Climate 
Change Plans related to the Nationally Determined Contributions (NDCs) committed by the country under the signed Paris Agreement. With respect to 
this, YPF signed a framework agreement with the Argentinean Environmental Authority for a mutual collaboration on environmental issues, particularly 
relating to climate change.

Water Management 

YPF is committed to an integrated water management approach focused on resource sustainability, as embodied in its corporate regulations. This means 
not  only  assessing  water  resources  in terms of  use,  but  also  of transportation and  storage;  consumption optimization,  ensuring  adequate treatment of 
process water to enable reuse; and analysis and treatment of liquid effluents. 

Along these lines, in 2015 we started a water management benchmarking study on several assets within the Downstream and Gas and Power businesses. 
The  three  industrial  refining  complexes,  Tucumán  Thermal  Power  Plant,  and  La  Matanza  Terminal  had  already  been  surveyed  in  2016.  In  2017  we 
finished surveying Dock Sud and La Plata Terminals, Escobar LNG Plant, and Y-TEC. This methodology improved our knowledge of water withdrawal 
sources and effluent disposal points and provided relevant volumes. 

A similar ongoing improvement process is carried out in the Upstream business. Based on a survey performed on all operations in 2015, this area has 
now an annually updated resource management plan. 

In 2018 we also continued implementing the Local Water Tool oriented to the identification of water risks and practices for an adequate management of 
water and effluents. In 2017 we analyzed Fernández Oro Station in the Province of Río Negro (Upstream) and Escobar LNG Plant, in the Province of 
Buenos Aires (Gas and Power). As a result, new potential risks were identified and included in the relevant action plans. Furthermore, during 2018 a 
particular  focus  has  been  placed  on  water  management,  dedicating  personnel  and  resources  exclusively  to  carry  out  a  detailed  study  of  water 
management for the different facilities of the Company, which allowed us to establish the water balances captured and produced and the identification of 
improvement and optimization actions for next years. 

Waste Management 

In compliance with Argentine regulations and our environmental standards, we develop integrated waste management activities seeking to: (a) phase out 
waste generation; (b) reduce waste hazardousness and ensuing environmental impacts; (c) ensure proper treatment and final disposal; and (d) establish 
continuous improvement programs. 

Since 2012, we have been working on initiatives in our Upstream business unit in order to systematically reduce the stock of soil with hydrocarbons. 
This is being performed with the commitment, leadership and responsibility of the entire Company achieving a reduction of 67% of the stock in our 
repositories from 2012 to October 2018. Some of the activities that allow us to achieve this target were related to actions to the providers, mainly with 
the  development  of  technical  specifications  for  the  contractual  arrangements  and  effective  technical  supervision  of  their  activities,  optimizing  the 
biotreatment times. 

During  2017,  the  treatment  of  plastic  materials contaminated  with  hydrocarbons  began  in  Santa  Cruz,  recovery  and  value  has  been  possible  through 
washing and recycling, prioritizing their reuse and avoiding their incineration, promoting a circular economy and reducing CO2 emissions. 

Furthermore, each business unit developed Waste Management Plans in line with the Upstream Waste Management Procedure and the Corporate Norm. 
Together  with  these  plans  the  Oil  spill  cleaning  procedure  was  also  developed  which  is  focused  on  the  minimization  of  waste  during  remediation 
activities. 

Spill Preparedness and Response 

The Company has a Spill Prevention and Control System in place that has helped to reduce the spill frequency rate for the past five years. This system 
provides an investment plan focused on the integrity, maintenance and improvement of facilities and pipelines. It includes a spill communication and 
response procedure reporting to a software program that automatically alerts the relevant environmental authority. 

In the specific Downstream business, improvement activities were aimed at storage, and truck and pipeline transportation. 

Management of biodiversity and ecosystem services 

In 2017 a revision on our corporate Biodiversity Management Standard was done with the participation of representatives of each Business Unit. This 
revision was performed as part of the update of the document. 

The management of biodiversity mainly focuses on instances where operations are being performed in ecological sensitive areas. These activities are 
being documented in the Biodiversity Management Plans. Currently, our Upstream business unit has two of these plans, one for our operations in the 
Llancanelo Ramsar site in the Mendoza province and another in the Auca Mahuida site in the Neuquén province. 

100 

The activities related to biodiversity management in many cases involve changes in operational procedures, such as multiple location development, the 
camouflage  of  drilling  equipment  and  even  actions  that  require  the  adaptation  of  the  operation  sites  in  order  to  promote  the  allocation  of  particular 
species. 

As  operations  continue  to  adapt,  biodiversity  monitoring  activities  are  also  being  performed  under  a  complex  process  due  to  the  frequent  natural 
variations  that  affects  the  wild  populations,  ecosystems  and  ecological  processes  in  the  medium  and  long  term.  This  is  done  in  order  to  gather 
information related to the local ecosystem and is focused on its protection and, when necessary, its restoration. This information is also important for the 
proper and sustainable use of natural resources before operations start. 

During 2018, we performed a technical study which analyzed and reported the degree of ecological restoration of sites devoid of vegetation in our Santa 
Cruz  operations.  The  area  under  study  encompassed  10  blocks,  or  concession  areas,  amounting  to  a  total  area  of  6,943  km2  and  1,968  abandoned 
locations. This technical study concluded that the vegetal coverage status of the area is similar to the environment, so these areas could be released to 
stop being an environmental liability. 

Environmental activities led by YPF in areas of unconventional exploitation of crude oil and natural gas 

Organically rich shale gas and oil accumulations are drawing increasing attention worldwide as sources of significant natural gas and oil reserves. 

Since 2008, YPF has led various exploration and development projects related to unconventional resources in Argentina, the most important being in the 
Vaca Muerta formation within Neuquina basin. 

The Vaca Muerta formation is found between 2,500 and 4,000 meters of depth, more than 2,000 meters below the water table, which is usually located 
at depths of 300-500 meters. See “Item 3. Key Information—Risk Factors—Risks Relating to Our Business—Our domestic operations are subject to 
extensive regulation” and “Item 3. Key Information—Risk Factors—Risks Relating to Our Business—Oil and gas activities are subject to significant 
economic, environmental, operational risks and seasonal fluctuation.” 

Hydraulic  stimulation,  a  long  time  proven  technology,  allows  these  resources  to  be  extracted  in  an  efficient  and  environmentally-friendly  way. 
Hydraulic stimulation consists of injecting high pressure fluids and sand into the wellbore to crack the rock and enable the trapped hydrocarbons in the 
formation to flow to the surface like in any conventional well. 

Generally, this technique uses water and sand (99.5% of the water can be recycled) and additives (0.5%). These additives are the same as those used in 
products for household and commercial applications, such as sodium chloride (used in table salt), borate salts (used in cosmetics), potassium carbonate 
(used in detergents), guar gum (used in ice cream) and isopropyl alcohol (used in deodorants). 

The water used for the development of these reservoirs is acquired from bodies of running water and it represents only a small percentage of the total 
flow, which involves much lower volumes than those used for agricultural and human consumption in the province of Neuquén. 

From  the  beginning  of  unconventional  operations,  YPF  has  considered  the  environmental  protection  as  one  of  the  values  of  its  health,  safety  and 
Operational Excellence policy. 

In  accordance  with  law  Disposition  No. 112/2011  of  the  Environmental  Subsecretary  of  Neuquén,  the  project  has  an  Environmental  Baseline  Study 
(“EBS”).  The  EBS  includes  the  current  description  and  environmental  characterization  of  the  concession  areas  and  specifically  environmental 
components that may be affected significantly by the projects and activities. 

YPF developed a water management framework, which focuses on three key areas of water use: water resources (sustainability factors, measures that 
consider the needs of other local water users, and the net environmental effect); water use and efficiency (controls of replacing water use, reducing water 
consumption, and the reuse and recycling to consider the net environmental effect); and wastewater management (consider similar sustainability factors 
and the net environmental effect as outlined for water resources). 

In  addition,  YPF  commissioned  the  following  studies:  (i) a  hydrogeological  study  of  confined  and  semi-confined  aquifers  of  Neuquén  and  Rayoso 
Groups and hydrogeological study of the unconfined aquifer of the alluvial plain of the Neuquén River in the Loma Campana area and (ii) a similar 
study in the Narambuena area, which was conducted in 2016. 

101 

After the hydrogeological studies carried out in 2015 and 2016, during 2017 YPF focused its studies on the gathering of hydrogeological information 
through  electrical  profiles  and  water  samples  in  order  to  obtain  the  baseline  data  for  a  regional  hydrogeological  study,  aimed  at  conventional  and 
unconventional  areas  in  Neuquén.  This  hydrogeological  study  was  completed  in  November  2018,  which  covered  not  only  the  traditional 
hydrogeological aspects but also the evaluation of water quality for irrigation and drinking water. The main objective of the study is the identification of 
the aquifers that must be protected. 

Our commitment to sustainability 

The oil and gas industry is undergoing a time of profound changes that require the harmonization of the growing energy demand with new challenges in 
terms  of  costs  and  profitability,  diversification  of  the  energy  matrix  and  an  increasing  concern  about  climate  change  and  the  decarbonization  of  the 
economy.  Each  region  or  country  will  have  to  develop  its  own  roadmap  for  transition  based  on  its  specific  starting  point,  resource  availability  and 
capabilities. 

In this context, YPF has started a transformation process to become an integral energy company and the leader for sustainable energy development in 
Argentina. YPF understands sustainability as a way of doing business that involves: 

• Transparent and responsible work at economic, environmental and social levels. 

• Profitability and focus on growth through innovation and new technologies. 

• Short and long-term value generation for shareholders, investors, partners, customers, employees, suppliers, the communities where we operate, 

and our country. 

This approach is described in the relevant Sustainability Policy and reflected in both our management system and operational excellence model, and we 
extend this challenge to our leaders, employees, suppliers and partners. 

The  Executive  Management  Committee,  through  each  one  of  its  members  and  their  respective  vice  presidencies,  reviews  and  monitors  relevant 
sustainability  topics.  The  Board  of  Directors  performs  these  duties  through  the  Risk  and  Sustainability  Committee.  This  Committee  is  in  charge  of 
establishing comprehensive management policies for business risks and monitoring their suitable implementation, as well as promoting best practices in 
sustainability, among other responsibilities. 

As such, we conduct our business in line with the goals of the Paris Climate Change Agreement signed in 2015, the United Nations 2030 Agenda for 
Sustainable Development Goals, and the UN Global Compact’s Ten Principles. 

Guided  by  the  company’s  corporate  values,  policies  and  code  of  conduct,  our  vision  and  strategy  frame  our  understanding  of  and  our  response  to 
sustainability issues. In this sense we have revamped our commitment to sustainability in order to lead the energy transition, through a responsible and 
transparent business based on innovation, new technologies and the best economic, environmental and social practices. And creating shared value for 
our owners, customers, people, suppliers, partners, society and our country, at the same time. 

While  oil  and  gas  will  continue  to  form  the  basis  of  our  portfolio  for  the  next  years,  we  are  committed  to  strengthening  energy  efficiency,  reducing 
specific  emissions and  developing more  sustainable  energy  alternatives,  including  the  promotion  of  natural  gas  production  and  renewable  energy  as 
cleaner  alternatives  to  oil.  We  plan  to  do  so  through  a  responsible  and  transparent  business  based  on  innovation,  new  technologies  and  the  best 
economic, operational excellence and transformation of operations and corporate culture. In particular in renewable energy, by providing strong R&D 
and project investment in this area, the company expects to increase its power-generation capacity by diversifying energy sources, including increased 
uses of natural gas, thermal, solar and wind power. 

In  2018  we  continued  working  on  our  corporate  sustainability  policy  and  our  commitment  to  climate  change  through  our  corporate  sustainability 
department. 

With the objective of consolidating our sustainability strategy and related initiatives, we focused 2018 activities in four main pillars: 

•

Implementation and improvements of initiatives in the main ESG issues: governance, transparency and integrity, human rights, labor 
practices, diversity, environment, health and safety, supply chain and relations with Communities.

Design of the five year Company Sustainability Plan, aligned with the global sustainability commitments we assumed. To do it, we 
developed -among others- an assessment of our performance according to worldwide recognized ESG ratings and an overall analysis 
of human rights (ending during 2019). 

Participation in global, national and local recognized organizations and initiatives regarding corporate and energy sustainability. In 
particular, our Chairman led during 2018 the B20 Task Force on Energy, Resource Efficiency and Sustainability and was appointed 
for the next two years as the President of the Argentinean Network of the United Nations Global Compact Initiative. 

Strengthening  of  the  communication  to  our  stakeholders  through:  the  annual  Sustainability  Report,  delivering  better  and  more 
focused communication on ESG matters; specific workshops for managers and employees in order to increase their knowledge about 
sustainability;  and  publishing  in  the  Argentinean  World  Business  Council  for  Sustainable  Development  (WBCSD)  platform  for 
Sustainable Development Goals the main initiatives that are already underway and that contribute towards the 2030 Global Agenda 
for Sustainable Development. 

Moreover, we updated the materiality assessment of ESG issues in order to strengthen our understanding about their concerns and expectations while 
keeping  an  ongoing  dialogue  with  them.  Their  opinions  and  suggestions  were  collected  in  several  dialogue  instances,  through  different  corporate 
communication channels,  and  by analyzing public opinion surveys,  media reports, and reputation  and  brand  positioning research,  among  others. The 
materiality assessment undertaken to shape the content of the 2017 sustainability report serves as both a retrospective and forward looking review of our 
priorities. This assessment re-emphasized the following stakeholder concerns:

In addition, YPF forms part of the first Sustainability Index of the Argentine stock market. Developed by Bolsas y Mercados Argentinos (BYMA), with 
the  collaboration  of  the  Inter-American  Development  Bank  and  Thomson  Reuters,  the  index  is  composed  by  companies  that  have  outstanding 
performance in sustainability. 

The index, which aims to promote an increasingly responsible capital market in line with the Sustainable Development Goals of the United Nations, 
evaluates  the  performance  of  the  Companies  on  four  axes:  environmental,  social,  corporate  governance  and  sustainable  development,  taking  into 
account  the  information  that  companies  communicate  through  their  Sustainability  Reports  and  corporate  reports  such  as  20-F.  Currently,  the 
Sustainability Index is integrated by 15 companies. 

Property, Plant and Equipment 

Most  of  our  property,  which  comprises  investments  in  assets  which  allow  us  to  explore  or  exploit  crude  oil  and  natural  gas  reserves,  as  well  as 
refineries,  storage,  manufacturing  and  transportation  facilities  and  service  stations,  is  located  in  Argentina.  See  “—Downstream—Refining  division” 
and “—Downstream—Logistic Division.” As of December 31, 2018, 100% of our proved reserves were located in Argentina. 

Our  petroleum  exploration  and  production  rights  are  in  general  based  on  sovereign  grants  of  concession.  Upon  the  expiration  of  the  concession,  our 
exploration and production assets associated with the particular property subject to the relevant concession revert to the government. See “—Upstream 
Overview—Main properties.” In addition, as of December 31, 2018, we leased 78 service stations to third parties and also had activities with service 
stations that are owned by third parties and operated by them under a supply contract with us for the distribution of our products. 

103 

Insurance 

The scope and coverage of the insurance policies and indemnification obligations discussed below are subject to change, and such policies are 
subject  to  cancellation  in  certain  circumstances.  In  addition,  the  indemnification  provisions  of  certain  of  our  drilling,  maintenance  and  other  service 
contracts may be subject to differing interpretations, and enforcement of those provisions may be limited by public policy and other considerations. We 
may also be subject to potential liabilities for which we are not insured or in excess of our insurance coverage, including liabilities discussed in “Item 3. 
Key Information—Risk Factors—Risks Relating to Our Business—We may not have sufficient insurance to cover all the operating hazards that we are 
subject to,” “Item 3. Key Information—Risk Factors—Risks Relating to Our Business—The oil and gas industry is subject to particular economic and 
operational risks” and “Item 3. Key Information—Risk Factors—Risks Relating to Our Business—We may incur significant costs and liabilities related 
to environmental, health and safety matters.” 

Argentine Operations 

We  insure  our  operations  against  risks  inherent  in  the  oil  and  gas  industry,  including  loss  of  or  damage  to  property  and  our  equipment, 
control-of-well  incidents, loss of production or profits incidents, removal of debris, sudden and accidental pollution, damage and clean up and third-
party  claims,  including  personal  injury  and  loss  of  life,  among  other  business  risks.  Our  insurance  policies  are  typically  renewable  annually  and 
generally contain policy limits, exclusions and deductibles. 

Our  insurance  policy  covering  our  Argentine  operations  provides  third  party  liability  coverage  up  to  U.S.$400 million  per  incident,  with  a 
deductible of U.S.$2 million, in each and every loss. Certain types of incidents, such as intentional pollution and gradual and progressive pollution are 
excluded from the policy’s coverage. The policy’s coverage extends to control-of-well incidents, defined as an unintended flow of drilling fluid, oil, gas 
or water from the well that cannot be contained by equipment on site, by increasing the weight of drilling fluid or by diverting the fluids safely into 
production. Our policy provides coverage for third-party liability claims relating to pollution from a control-of-well event ranging from U.S.$ 75 million 
for certain onshore losses and a maximum combined single limit of U.S.$ 250 million for offshore losses. 

Our  insurance  policy  also  covers  physical  loss  or  damage  in  respect  of,  but  not  limited  to,  onshore  and  offshore  property  of  any  kind  and 
description  (whether  upstream  or  downstream),  up  to  U.S.$  2 billion  per  incident  combined  for  downstream  and  upstream  operations,  with  varying 
deductibles  of  between  U.S.$  1 million  and  U.S.$  5 million,  including  loss  of  production  or  profits  with  deductibles  of  90  days  for  downstream 
operations and 60 days with a minimum deductible of U.S.$ 20 million for upstream operations. 

Argentine regulations require us to purchase from specialized insurance companies (Aseguradoras de Riesgos de Trabajo) insurance covering the 
risk of personal injury and loss of life of our employees. Our insurance policies cover medical expenses, lost wages and loss of life, in the amounts set 
forth in the applicable regulations. These regulatory requirements also apply to all of our contractors. 

We  have  adopted  a  position  in  agreements  entered  into  with  contractors  that  provide  drilling  services,  well  services  or  other  services  to  our 
exploration  and  production  operations  (“E&P  Services  Agreements”),  whereby  contractors  are  generally  responsible  for  indemnifying  us  to  varying 
degrees for certain damages caused by their personnel and property above the drilling surface. Similarly, we are generally responsible under our drilling 
contracts to indemnify our contractors for any damages caused by our personnel and property above the drilling surface. 

In connection with losses or liabilities resulting from damages caused below the surface, we have agreed with some contractors that YPF assumes 
responsibility for indemnifying our contractors provided that such damages below the surface have not been caused by the negligence of the contractor 
in which case the contractor shall be liable up to a limited amount agreed by the parties in the E&P Services Agreements. However, we have also agreed 
with a number of contractors that YPF shall be responsible and shall indemnify contractors for damages or liabilities caused below the surface, unless 
such damages or liabilities result from the gross negligence or willful misconduct of contractors, in which case contractor shall be liable in full or, in 
certain cases, up to a limited amount. 

E&P Services Agreements usually establish that contractors are responsible for pollution or contamination including clean-up costs and third party 
damages caused above the surface by the spill of substances under their control, provided that the damage has been caused by the negligence or willful 
misconduct  of  the  contractor.  In  the  event  of  pollution  or  contamination  produced  below  the  surface,  contractors  shall  also  typically  be  liable  for 
damages caused due to the contractor’s negligence or willful misconduct. However, in this last case the damages are also usually limited to an amount 
agreed upon by the parties in the E&P Services Agreement. 

We are also partners in several joint ventures and projects that are not operated by us. Contractual provisions, as well as our obligations arising 

from each agreement, can vary. In certain cases, insurance coverage is provided by the insurance policy entered into 

104 

by the operator, while in others, our risks are covered by our insurance policy covering our Argentine operations. In addition, in certain cases we may 
contract insurance covering specific incidents or damages that are not provided for in the operator’s insurance policy. We also retain the risk for liability 
not indemnified by the field or rig operator in excess of our insurance coverage. With respect to downstream servicing contracts, contractors are usually 
responsible for damages to their own personnel and caused by them to third parties and they typically indemnify us for damages to equipment. 

Legal and Regulatory Framework and Relationship with the Argentine Government 

Overview 

The  Argentine  oil  and  gas  industry  is  regulated  by  Law  No. 17,319,  referred  to  as  the  “Hydrocarbons  Law,”  which  was  enacted  in  1967  and 
amended  by  Law  No. 26,197  enacted  in  2007  and  by  Law  No. 27,007  enacted  in  2014,  which  established  the  general  legal  framework  for  the 
exploration and production of oil and gas, and by Law No. 24,076, referred to as the “Natural Gas Law,” enacted in 1992, which established the basis 
for deregulation of natural gas transportation and distribution industries. See “—Law No. 27,007 (amendment of the Hydrocarbons Law).” 

The  National  Executive  Office  issues  the  regulations  to  complement  these  laws.  The  regulatory  framework  of  the  Hydrocarbons  Law  was 
established  on  the  assumption  that  the  reservoirs  of  hydrocarbons  would  be  national  properties  and  Yacimientos  Petrolíferos  Fiscales  Sociedad  del 
Estado, our predecessor, would lead the oil and gas industry and operate under a different framework than private companies. In 1992, the “Privatization 
Law” privatized YPF and provided for transfer of hydrocarbon reservoirs from the Argentine government to the provinces, subject to the existing rights 
of the holders of exploration permits and production concessions. 

The  Privatization  Law  granted  us  24  exploration  permits  covering  approximately  132,735  km2  and  50  production  concessions  covering 
approximately 32,560 km2. Limits under the Hydrocarbons Law on the number of concessions for transportation that may be held by any entity, and the 
total  area  of  exploration  permits  that  may  be  granted  to  a  single  entity,  were  eliminated  by  Law  No. 27,007.  As  a  consequence  of  the  transfer  of 
ownership  of  certain  hydrocarbons  areas  to  the  provinces,  we  participate  in  competitive  bidding  rounds  organized  since  the  year  2000  by  several 
provincial governments for the award of contracts for the exploration of hydrocarbons. 

In  October  2004,  the  Argentine  Congress  enacted  Law  No. 25,943,  creating  a  new  state-owned  energy  company,  Energía  Argentina  Sociedad 
Anónima (“ENARSA”). The corporate purpose of ENARSA is the exploration and exploitation of solid, liquid and gaseous hydrocarbons, the transport, 
storage,  distribution,  commercialization  and  industrialization  of  these  products,  as  well  as  the  transportation  and  distribution  of  natural  gas,  and  the 
generation, transportation, distribution and sale of electricity. Moreover, Law No. 25,943 granted to ENARSA all exploration concessions in respect to 
offshore areas located beyond 12 nautical miles from the coast line up to the outer boundary of the continental shelf that were vacant at the time of the 
effectiveness of this law (i.e., November 3, 2004). Law No. 25,943 has been modified by Law No. 27,007, as described below, eliminating all permits 
and offshore hydrocarbon production concessions where association agreements with ENARSA have not been signed and reverting them to the SGE 
(except  for  permits  and  concessions  granted  prior  to  Law  No. 25,943).  Additionally,  Law  No. 27,007  provides  for  a  six  month  negotiating  period  to 
convert  association  agreements  with  ENARSA  into  permits  or  concessions.  In  September  2015,  the  National  Executive  Office  and  YPF  began 
negotiating the conversion of association agreements executed with ENARSA. On December 29, 2017 YPF filed a note before the Ministry of Energy 
confirming its willingness to negotiate the conversion of association agreement related to the Area identified as “ENARSA 1”. In the same note, YPF 
informed its decision not to convert the association agreements related such Areas to the Operators of Areas “ENARSA 2” and “ENARSA 3”. Likewise, 
on October 19, 2018, YPF formally presented a draft agreement for the conversion of the association agreement for Area “ENARSA 1”, which, as of the 
date of this annual report, is still under review. 

In addition, in October 2006, Law No. 26,154 created a regime of tax incentives aimed at encouraging hydrocarbon exploration and which apply 
to  new  exploration  permits  awarded  in  respect  of  the  offshore  areas  granted  to  ENARSA  and  those  over  which  no  rights  have  been  granted  to  third 
parties under the Hydrocarbons Law, provided the provinces in which the hydrocarbon reservoirs are located adhere to this regime. Association with 
ENARSA is a precondition to qualifying for the benefits provided by the regime created by Law No. 26,154. The benefits include: early reimbursement 
of  the  value  added  tax  for  investments  made  and  expenses  incurred  during  the  exploration  period  and  for  investments  made  within  the  production 
period;  accelerated  amortization  of  investments  made  in  the  exploration  period  and  the  accelerated  recognition  of  expenses  in  connection  with 
production over a period of three years rather than over the duration of production; and exemptions to the payment of import duties for capital assets not 
manufactured within Argentina. As of the date of this annual report, we have not used the tax incentives previously mentioned.

In 1992, the Privatization Law approved the transfer of the ownership of hydrocarbons reserves to the provinces where they are located. However, 
this law provided that the transfer was conditioned on the enactment of a law amending the Hydrocarbons Law to contemplate the privatization of 
Yacimientos Petrolíferos Fiscales Sociedad del Estado. 

In  October  1994,  the  Argentine  National  Constitution  was  amended  and  pursuant  to  Article  124  thereof,  provinces  were  granted  the  primary 
control of natural resources within their territories. 

In August 2003, Executive Decree No. 546/03 transferred to the provinces the right to grant exploration permits, hydrocarbons exploitation and 
transportation  concessions  in  certain  locations  designated  as  “transfer  areas,”  as  well  as  in  other  areas  designated  by  the  competent  provincial 
authorities. 

In January 2007, Law No. 26,197 acknowledged the provinces’ ownership of the hydrocarbon reservoirs in accordance with Article 124 of the 
National Constitution (including reservoirs to which concessions were granted prior to 1994) and granted provinces the right to administer such 
reservoirs. 

Decree No 882/2017 

On November 1, 2017, Decree No. 882/2017 was published in the Official Gazette, which ordered the merger of ENARSA and Emprendimientos 

Energéticos Binacionales Sociedad Anónima (EBISA) and formed a new company named Integración Energética Argentina S.A. (“IEASA”). 

The Expropriation Law 

On May 3, 2012, the Expropriation Law (Law No. 26,741) was passed by the Argentine Congress and, on May 7, 2012, it was published in the 
Official  Gazette.  The  Expropriation  Law  declared  achieving  self-sufficiency  in  the  supply  of  hydrocarbons,  as  well  as  in  the  exploitation, 
industrialization,  transportation  and  sale  of  hydrocarbons,  a  national  public  interest  and  a  priority  for  Argentina.  In  addition,  its  stated  goal  is  to 
guarantee  socially  equitable  economic  development,  the  creation  of  jobs,  the  increase  of  the  competitiveness  of  various  economic  sectors  and  the 
equitable and sustainable growth of the Argentine provinces and regions. 

Article 3 of the Expropriation Law provides that the principles of the hydrocarbon policy of the Republic of Argentina are the following: 

• Promote the use of hydrocarbons and their derivatives to promote development, and as a mechanism to increase the competitiveness of the various 

economic sectors and that of the provinces and regions of Argentina; 

• Convert hydrocarbon resources to proved reserves and their exploitation and the restoration of reserves; 

•

Integrate  public  and  private  capital,  both  national  and  international,  into  strategic  alliances  dedicated  to  the  exploration  and  exploitation  of 
conventional and unconventional hydrocarbons; 

• Maximize  the  investments  and  the  resources  employed  for  the  achievement  of  self-sufficiency  in  hydrocarbons  in  the  short,  medium  and  long 

term; 

•

Incorporate  new  technologies  and  categories  of  management  that  contribute  to  the  improvement  of  hydrocarbon  exploration  and  exploitation 
activities and the advancement of technological development in the Republic of Argentina in this regard; 

• Promote the industrialization and sale of hydrocarbons with a high added-value; 

• Protect the interests of consumers with respect to the price, quality and availability of hydrocarbon derivatives; and 

• Export hydrocarbons produced in excess of local demand, in order to improve the trade balance, ensuring a rational exploitation of the resources 

and the sustainability of its exploitation for use by future generations. 

106 

According to Article 2 of the Expropriation Law, the National Executive Office will be responsible for setting forth this policy and shall introduce 
the measures necessary to accomplish the purpose of the Expropriation Law with the participation of the Argentine provinces and public and private 
capital, both national and international. 

Creation of Federal Council of Hydrocarbons 

Article 4 of the Expropriation Law provides for the creation of a Federal Council of Hydrocarbons which shall include the participation of (a) the 
Ministry of Economy, the Ministry of Federal Planning, the Ministry of Labor and the Ministry of Industry, through their respective representatives; and 
(b) the  provinces  of  Argentina  and  the  City  of  Buenos  Aires,  through  the  representatives  that  each  may  appoint.  According  to  Article  5  of  the 
Expropriation Law, the responsibilities of the Federal Council of Hydrocarbons will be the following: (a) promote the coordinated action of the national 
and provincial governments, with the purpose of ensuring the fulfillment of the objectives of the Expropriation Law; and (b) adopt decisions regarding 
all questions related to the accomplishment of the objectives of the Expropriation Law and the establishment of the hydrocarbons policy of the Republic 
of Argentina that the National Executive Office may submit for consideration. 

Federal Council of Energy 

On  October 26,  2017,  Decree  No. 854/2017  was  published  in  the  Official  Gazette,  creating  the  Federal  Council  of  Energy  which  includes  the 
participation of the Federal Government as well as of the provinces of Argentina and the Autonomous City of Buenos Aires. The Federal Council of 
Energy shall act as an advisory body on all the matters related to energy development of the Republic of Argentina. 

Expropriation of shares held by Repsol YPF 

For purposes of ensuring the fulfillment of its objectives, the Expropriation Law provided for the expropriation of 51% of the share capital of YPF 
represented  by  an  identical  stake  of  Class D  shares  owned,  directly  or  indirectly,  by  Repsol  YPF  S.A.  and  its  controlled  or  controlling  entities. 
According  to  the  Expropriation  Law,  the  shares  subject  to  expropriation,  which  have  been  declared  of  public  interest  and  were  transferred  to  the 
Republic  of  Argentina,  will  be  assigned  as  follows:  51%  to  the  Argentine  Republic  and  49%  to  the  governments  of  the  provinces  that  compose  the 
National Organization of Hydrocarbon Producing States. In addition, the Expropriation Law provided for the expropriation of 51% of the share capital 
of the company Repsol YPF GAS S.A. represented by 60% of the Class A shares of such company owned, directly or indirectly, by Repsol Butano S.A. 
and its controlled or controlling entities. 

As of the date of this annual report, the transfer of the shares subject to expropriation between the National Executive Office and the provinces 
that  compose  the  National  Organization  of  Hydrocarbon  Producing  States  is  still  pending.  According  to  Article  8  of  the  Expropriation  Law,  the 
distribution of the shares among the provinces that accept their transfer must be conducted in an equitable manner, considering their respective levels of 
hydrocarbon production and proved reserves. 

To ensure compliance with its objectives, the Expropriation Law provides that the National Executive Office, by itself or through an appointed 
public entity, shall exercise all the political rights associated with the shares subject to expropriation until the transfer of political and economic rights to 
the provinces that compose the National Organization of Hydrocarbon Producing States is completed. In addition, in accordance with Article 9 of the 
Expropriation Law, each of the Argentine provinces to which shares subject to expropriation are allocated must enter into a shareholder’s agreement 
with the federal government that will provide for the unified exercise of its rights as a shareholder. 

Any future transfer of the shares subject to expropriation is prohibited without the permission of the Argentine Congress by a vote of two-thirds of 

its members. 

In  accordance  with  Article  9  of  the  Expropriation  Law,  the  appointment  of  YPF  Directors  representing  the  expropriated  shares  shall  be  made 
proportionately considering the holdings of the Argentine Republic and provincial governments, and one Director shall represent the employees of YPF. 

In  accordance  with  Article  16  of  the  Expropriation  Law,  the  federal  government  and  the  provinces  must  exercise  their  rights  pursuant  to  the 
following principles: (a) the strategic contribution of YPF to the achievement of the objectives set forth in the Expropriation Law; (b) the administration 
of YPF pursuant to the industry’s best practices and corporate governance, safeguarding shareholders’ interests and generating value on their behalf; and 
(c) the professional management of YPF.

expropriation  of  51%  of  the  share  capital  of  YPF  owned,  directly  or  indirectly,  by  Repsol,  and  the  arrangement  between  Repsol  and  YPF  for  the 
withdrawal of certain claims and actions relating to such expropriation. 

Legal nature of the Company 

YPF is and will continue to operate as a publicly traded corporation pursuant to Chapter II, Section V of Law No. 19,550 and its corresponding 
regulations, and neither is nor will not be subject to any legislation or regulation applicable to the management or control of companies or entities owned 
by the federal government or provincial governments. 

In  accordance  with  Article  17  of  the  Expropriation  Law,  YPF  will  resort  to  internal  and  external  sources  of  funding,  strategic  alliances,  joint 

ventures, transitory business unions, and cooperation partnerships, whether public, private or mixed companies, domestic and foreign.

Law No. 26,932 

On February 25, 2014, the Republic of Argentina and Repsol reached an agreement (the “Repsol Agreement”) in relation to compensation for the 
expropriation of 200,589,525 of YPF’s Class “D” shares pursuant to the Expropriation Law under the Repsol Agreement. As a result, the Republic of 
Argentina is definitively the owner of 51% of capital stock of each of YPF and YPF GAS S.A. 

Law No. 26,197 

Law No. 26,197, which amended the Hydrocarbons Law, transferred to the provinces and to the Autonomous City of Buenos Aires the ownership 
over  all  hydrocarbon  reservoirs  located  within  their  territories  and  in  the  adjacent  seas  up  to  12  nautical  miles  from  the  coast.  Law  No. 26,197  also 
provides that the hydrocarbon reservoirs located beyond 12 nautical miles from the coast to the outer limit of the continental shelf shall remain within 
the ownership of the federal government. 

Pursuant to Law No. 26,197, the Argentine Congress shall continue to enact laws and regulations to develop oil and gas resources existing within 
the Argentine territory (including its sea), but the governments of the provinces where the hydrocarbon reservoirs are located shall be responsible for the 
enforcement of these laws and regulations, the administration of the hydrocarbon fields and shall act as granting authorities for the exploration permits 
and production concessions. However, the administrative powers granted to the provinces shall be exercised within the framework of the Hydrocarbons 
Law and the regulations that complement this law. 

Consequently,  even  though  Law  No. 26,197  established  that  the  provinces  shall  be  responsible  for  administering  the  hydrocarbon  fields,  the 
Argentine Congress retained its power to issue rules and regulations regarding the oil and gas legal framework. Additionally, the Argentine Republic 
retained the power to determine the national energy policy. 

It  is expressly stated that  the transfer  will not affect the  rights  and  obligations of exploration  permit  and  production concession holders, or the 
basis for the calculation of royalties, which shall be calculated in accordance with the concession title and paid to the province where the reservoirs are 
located. 

Law  No. 26,197  provides  that  the  Argentine  Republic  shall  retain  the  authority  to  grant  transportation  concessions  for:  (i) transportation 
concessions  located  within  two  or  more  provinces  within  the  territory  and  (ii) transportation  concessions  directly  connected  to  export  pipelines  for 
export purposes. Consequently, transportation concessions which are located within the territory of only one province and which are not connected to 
export  facilities  shall  be  transferred  to  the  provinces.  Finally,  Law  No. 26,197  grants  the  following  powers  to  the  provinces:  (i) the  exercise,  in  a 
complete  and  independent  manner,  of  all  activities  related  to  the  supervision  and  control  of  the  exploration  permits  and  production  concessions 
transferred by Law No. 26,197; (ii) the enforcement of all applicable legal and/or contractual obligations regarding investments, rational production and 
information and surface fee and royalties payment; (iii) the extension of legal and/or contractual terms; (iv) the application of sanctions provided in the 
Hydrocarbons Law; and (v) all the other faculties related to the granting power of the Hydrocarbons Law.

Decree No. 1,277/2012 

Decree No. 1,277/12 derogated the main provisions relating to free availability of hydrocarbons which were specifically contained in section 5 
subsection  d)  and  sections  13,  14  and  15  of  Decree  No. 1,055/89,  sections  1,  6  and  9  of  Decree  No. 1,212/89  and  sections  3  and  5  of  Decree 
No. 1,589/89. Decree No. 1,277/12 enacted the “Hydrocarbons Sovereignty Regime Rules,” regulating the Expropriation Law. 

This regulation created a commission, the Commission for Planning and Strategic Coordination of the National Plan of Hydrocarbons Investments 

(the “Commission”). This Commission was entrusted with annually making the National Plan for Hydrocarbons Investments. 

Decree  No. 1,277/12  required  every  company  that  performs  activities  of  exploration,  exploitation,  refining,  transport  and  commercialization  of 
hydrocarbons to  supply the  Commission  with  all required technical information. The Commission was  also  responsible for  a  National  Hydrocarbons 
Investments  Registry  for  all  companies  performing  the  activities  of  exploration,  exploitation,  refining,  transport  and  commercialization.  All  these 
companies were required to file an annual plan of investments before September 30 of each year, including a detail of their quantitative goals regarding 
exploration, exploitation, refining and / or commercialization and transportation of hydrocarbons and fuels. 

With respect to the refining industry, Decree No. 1,277/12 gave the Commission the power to regulate the minimum utilization rates for primary 
or  secondary  refining.  It  also  had  the  ability  to  enact  measures  of  promotion  and  coordination,  aimed  to  guarantee  the  development  of  the  local 
processing capacity according with the goals established by the National Plan of Hydrocarbons Investments. 

With respect to commercialization, the Commission was entitled to publish reference prices of every component of the costs and sales prices of 
hydrocarbons and fuels, which should enable the recovery of production costs plus a reasonable profit margin. The Commission also had to periodically 
audit the reasonability of the informed costs and the respective sales prices, being entitled to adopt necessary measures to prevent or correct distortive 
practices that might affect the interests of consumers. 

This  Commission  was  dissolved  by  Decree  No. 272/2015  on  January 4,  2016,  and  its  remaining  functions  were  assumed  by  the  Ministry  of 

Energy and Mining. See “—Decree No. 272/2015” below. 

Decree No. 13/2015 

On  December 11,  2015,  Decree  No. 13/2015  was  published  in  the  Official  Gazette,  modifying  the  Ministries  Law  No. 22,520.  Among  other 
changes,  it  created  the  Ministry  of  Energy  and  Mining  (“MINEM”),  which  absorbed  the  functions  of  the  Secretaries  of  Energy  and  Mining  and 
decentralized  entities,  from  the  former  Ministry  of  Federal  Planning,  Public  Investment  and  Services.  The  responsibilities  of  the  MINEM  include 
participating “in the management of the State’s shareholdings in the corporations and companies operating in the area of its competence”. 

This Decree was modified by Decree No. 575/2018 published in the Official Gazette on June 22, 2018, and the Ministry of Energy and Mining 

was substituted by the Ministry of Energy. The Secretariat of Mining now reports to the Ministry of Production. See “—Decree No. 575/2018” below. 

Decree No. 272/2015 

On January 4, 2016, Decree No. 272/2015 was published in the Official Gazette, which modified Decree No. 1,277/12. Among other changes, it 
dissolved the Commission, derogated certain responsibilities of the Commission and stated that the tasks previously assigned to the Commission will be 
performed by the Ministry of Energy and Mining (“MINEM”). 

Furthermore, the decree established that the rights derived from the shares owned by the Republic of Argentina in YPF and YPF GAS S.A., with 
the  exception  of  the  shares  that  belong  to  the  Sustainability  Guarantee  of  the  Public  Securities  Regime  Fund  created  by  Decree  No. 897/07,  will  be 
exercised by the MINEM, as of its publication date. 

In addition, the decree established that the MINEM will conduct a comprehensive review and reorganization regarding the creation of records and 
information duties in the hydrocarbon industry, which remains in force as long as it is not derogated by the dispositions of the decree or addressed by the 
re-organization plan to be determined by the MINEM (See “—Decree No. 575/2018” below). 

109 

Decree No. 2/2017 

On January 3, 2017, Decree No. 2/2017 was published in the Official Gazette, modifying the Ministries Law No. 22,520. Among other changes, it 
split the Ministry of Treasury and Public Finance, creating the Ministry of Treasury and the Ministry of Finance and separating their respective powers 
and responsibilities. 

Decree No. 575/2018 

On June 22, 2018, Decree No. 575/2018 was published in the Official Gazette, modifying the Ministries Law No. 22,520. Among other changes, 

the Ministry of Energy and Mining was substituted by the Ministry of Energy. The Secretariat of Mining now reports to the Ministry of Production. 

This  Decree  was  modified  by  Decrees  No. 801/2018  and  No. 802/2018,  and  the  Ministry  of  Energy  was  substituted  by  the  Secretary  of 

Government of Energy (“SGE”), which now reports to the Ministry of Treasury. See “—Decree No. 801/2018 and Decree No. 802/2018” below. 

Decree No. 801/2018 and Decree No. 802/2018 

On  September 5,  2018,  Decree  No. 801/2018  was  published  in  the  Official  Gazette,  modifying  the  Ministries  Law  No. 22,520.  Among  other 

changes, the Ministry of Energy was dissolved, and the Ministry of Treasury was appointed as successor of the Ministry of Energy. 

On that date also, Decree No. 802/2018 was published in the Official Gazette which creates the SGE. 

Decree No. 872/2018 

On October 2, 2018, Decree No. 872/2018 was published in the Official Gazette, instructing the SGE to issue a public invitation to tender for the 
grating  of  exploration  permits  for  the  offshore  area.  This  tender  was  issued  on  November 6,  2018,  according  to  the  terms  set  forth  in  Decree 
No. 872/2018. 

Law No. 27,275, Decree No. 79/2016 and Regulatory Decree No. 206/2017 - Access to Public Information 

On November 10, 2015, the Argentine Supreme Court ordered us to furnish information regarding an agreement we entered into with Chevron, 
based  on  the  requirements  of  Decree  No. 1,172/03,  which  regulates  access  to  information  considered  public.  The  agreement  aims  to  develop 
hydrocarbon resources in Argentina. The information was delivered to the court on February 23, 2016. We believe that public disclosure of confidential 
information  could  put  us  at  a  competitive  disadvantage  in  relation  to  our  contracting  parties  and  potential  partners.  For  this  reason,  and  given  the 
business, industrial, technical, economic and financial value as well as the nature of the information requested, we pursued all avenues to preserve its 
confidentiality. We have stated we intend to comply with the requirements of aforementioned Decree No. 1,172/03 while preserving our right to keep 
certain  industrial,  commercial,  financial  and  technical  matters  confidential  as  provided  by  the  decree.  Notwithstanding  the  foregoing,  on  March 14, 
2016, the court ordered us to deliver the requested agreement within five business days without an opportunity to keep certain information confidential 
as  requested  by  us  and  in  accordance  with  the  exemptions  contemplated  by  Decree  No. 1,172/03.  On  March 16,  2016,  the  Company  appealed  this 
decision. 

On July 14, 2016, the Federal Administrative Court  – Room I (Cámara Contencioso Administrativo Federal – Sala I) upheld the ruling of the 
Court of First Instance, stipulating that the Company must comply with the order to deliver the required documentation in relation to its agreement with 
Chevron within five business days. 

On August 11, 2016, the Company filed a Federal Extraordinary Appeal contesting the decision of the Federal Administrative Court. 

On September 22, 2016, the Company reported that it was served with notice on September 15, 2016 of the decision handed down by Panel I of 
the Federal Administrative Court of Appeals hearing Disputed Administrative Matters (Cámara Contencioso Administrativo Federal), which rejected 
the  Federal  Extraordinary  Appeal  filed  by  the  Company  from  such  Panel’s  docket  that  ordered  the  Company  to  deliver  the  Project  Investment 
Agreement (“PIA”) executed with Chevron on July 16, 2013. 

The Company submitted a full copy of the PIA in compliance with the decision of the Federal Administrative Court – Room I. 

In both cases, the Company noted that the PIA was entered into under Law No. 19,550 and the confidentiality of the terms thereof was intended to 

safeguard geological, commercial and financial information, which was of strategic value to both parties to the PIA. 

110 

Delivery of the PIA does not imply the Company’s waiver of rights in the event that any other confidential information and/or documents of the 

Company are required to be disclosed in the future. 

On  September 29,  2016,  Law  No. 27,275  was  published  in  the  Official  Gazette,  guaranteeing  the  general  public’s  right  to  access  public 
information. This right includes the ability to freely seek, access, request, receive, copy, analyze, process, use and distribute information in possession of 
the parties subject to this law. State owned companies, companies where the state owns a majority of their capital stock, mixed economy companies and 
all other business organizations where the National Government has a majority interest in the capital stock or has the ability to adopt corporate decisions 
are deemed the parties subject to this law, with a specific exception for those companies who are authorized to make public offerings of their securities. 
Law No. 27,275 came into effect one year after its publication in the Official Gazette. 

On January 31, 2017, Decree No. 79/2017 was published in the Official Gazette, modifying the public information access right established under 
the  “General  Regulation  of  Access  to  Public  Information  for  the  National  Executive  Office.”  The  decree  established  that  exceptions  to  the  scope  of 
parties subject to the law would become effective the day after their publication in the Official Gazette. 

On March 28, 2017 Regulatory Decree No. 206/2017 was published in the Official Gazette and came into effect on September 29, 2017, which 
regulates  certain  aspects  of  Law  No. 27,275,  including  further  clarifications  with  respect  to  scope  of  the  exceptions  to  the  obligation  of  the  parties 
subject to this law to furnish certain information. 

Law No. 27,007 (amendment of the Hydrocarbons Law) 

On October 31, 2014, Law No. 27,007 amending the Hydrocarbons Law was published in the Official Gazette. The Hydrocarbons Law applies in 

certain aspects of some of YPF’s existing concessions, as well as future concessions. The most relevant modifications in that law are detailed below. 

• With  respect  to  exploration  permits,  it  distinguishes  between  those  with  conventional  and  unconventional  objectives,  and  those  in  which 
exploration is undertaken in the territorial sea and continental shelf. Law No. 27,007 modifies the basic time periods governing such activities, 
from three to two periods and limiting the two basic periods to (i) three years each for exploration with conventional objectives and (ii) four years 
each for exploration with unconventional objectives and (iii) four years each for exploration in the territorial sea or on the continental shelf. In 
each of these cases, the extension period of up to five years (already established in the Hydrocarbons Law) is maintained, although it is subject to 
the permit holder having complied with its investment and other obligations. At the end of the first basic period and so long as the permit holder 
has complied with its obligations under the permit, the permit holder may continue to hold the entire area. After the second basic period ends, the 
permit holder may surrender the entire area or, if the holder decides to trigger the extension period, 50% of the remaining area. 

•

In  relation  to  concessions,  Law  No. 27,007  provides  for  three  types  of  concessions:  conventional  production,  unconventional  production  and 
production  in  the  territorial  sea  or  on  the  continental  shelf.  Each  of  these  concessions  will  last  25,  35  and  30  years,  respectively.  In  addition, 
permit holders or production concessionaires may request unconventional production concessions on the basis of the development of a pilot plan. 
So  long  as  the  concessionaires  (i) have  complied  with  their  obligations,  (ii) are  producing  hydrocarbons  in  the  areas  under  consideration  and 
(iii) present an investment plan for the development of such areas as requested by the competent authorities up to a year prior to the termination of 
each term of the concession, they may request extension periods of ten years each. 

• The amounts to be paid with respect to annual surface fee pursuant to Sections 57 and 58 of the Hydrocarbons Law for the periods of exploration 
and production have been increased with the goal of incentivizing exploration and development of these areas. Additionally, beginning with the 
second basic exploration period, these may be reduced partially in light of investments actually carried out in the relevant areas. Restrictions on 
the number of exploration permits and/or production concessions that an individual or legal entity may hold were eliminated. 

• The  Hydrocarbons  Law  established  a  35-year  term  for  those  concessions  granted  for  the  transportation  of  oil,  gas  and  petroleum  products  that 
holders of production concessions are entitled to receive. Law No. 27,007 modified the awarded term for hydrocarbon transportation concessions 
to be synchronized with the production concession periods. 

111 

•

In connection with exploration and production offerings, tenders may be made by Argentine and foreign companies, with the goal of obtaining the 
highest number of tenders possible. In addition, the bidding documents must be prepared by the competent authorities on the basis of the model 
bidding document which will be drafted jointly by the competent authorities of the provinces and the SGE. This model bidding document must be 
prepared within 180 days of the effective date of Law No. 27,007. Tenders will be awarded to offerors who present the most relevant offer, in 
particular, the one proposing the highest amount of investments or exploratory activity. 

• Royalties have been set at a maximum of 12% on the results of liquid hydrocarbons or natural gas production. Royalties may be reduced, taking 
into account the productivity of the area and the type of production. In cases of extension periods, an additional royalty of 3% will be added for 
each  extension,  up  to  a  maximum  of  18%.  In  addition,  in  case  of  such  extensions,  the  competent  authority  may  include  the  payment  of  an 
extension bond, which maximum amount shall equal the result of multiplying the remaining proved reserves at the end of the concession period to 
be  extended  by  2%  of  the  average  basin  price,  for  the  two-year  period  prior  to  the  moment  when  the  extension  is  granted,  applicable  to  the 
hydrocarbons at issue. 

• Law No. 27,007 also provides that the Argentine Republic and the provinces may not establish, in the future, new areas reserved in favor of state-
owned entities or companies with state participation. Further, with respect to existing reserved areas that do not have association agreements with 
third parties as of the date of this new law, associative schemes may be carried out so long as, during the development phase, the participation of 
state-owned entities or companies with state participation is proportional to the effective investments promised and carried out by them. 

• Law  No. 27,007  additionally  incorporates  into  the  Investment  Promotion  Regime  for  the  Exploration  of  Hydrocarbons  (Decree  No. 929/2013) 
projects, as authorized by the MINEM, that imply direct investments in foreign currency greater than U.S.$ 250 million to be invested during the 
first three years of the project. Also, it modifies the percentages of hydrocarbons that, beginning with the third year, will be subject to the benefits 
of the  regime. For  conventional  and  unconventional production concessions, as well as offshore concessions at  depths less  than or equal  to 90 
meters, the percentage shall be 20%; for offshore concessions at depths greater than 90 meters, the percentage shall be 60%. 

• Within the framework of the Investment Promotion Regime for the Exploration of Hydrocarbons, Law No. 27,007 provides for contributions by 
companies to the provinces where the projects take place, which amount to 2.5% of the initial investment amount of the project, to be directed to 
“Corporate Social Responsibility” contributions. In addition, an amount to be determined by the Commission in light of the extent of the project 
must be contributed by the Argentine Republic to finance infrastructure. 

• Law No. 27,007 establishes that capital goods and inputs that are essential to the execution of the investment plans of companies registered in the 
National  Registry  of  Hydrocarbon  Investments  shall  pay  import  duties  as  indicated  in  Decree  No. 927/13  (reduced  rates).  This  list  may  be 
extended to other strategic products. 

• According  to  Law  No. 27,007,  the  federal  government  and  the  provinces  shall  attempt  to  establish  uniform  environmental  legislation  and  the 
adoption of uniform fiscal treatment in this sector. The competent authorities, including the SGE and the MINEM, will promote unification of 
procedures and registries. 

• All national offshore permits and offshore hydrocarbon production concessions that had no association agreements with ENARSA as of the date 
of the new law reverted and were transferred to the SGE. Permits and concessions granted prior to Law No. 25,943 shall be exempted from this 
provision.  The  National  Executive  Office  may  negotiate,  for  180  days  following  the  enactment  of  the  new  law,  the  conversion  of  association 
agreements  signed  with  ENARSA  to  permits  or  production  concessions.  In  September  2015,  the  National  Executive  Office  and  YPF  began 
negotiating the conversion of association agreements executed with ENARSA. On December 29, 2017 YPF filed a note before the Ministry of 
Energy confirming its willingness to negotiate the conversion of association agreement related to the Area identified as “ENARSA 1”. Likewise, 
on October 19, 2018, YPF formally presented a draft agreement for the conversion of the association agreement for Block ENARSA 1, which, as 
of  the  date  of  this  annual  report,  is  still  under  review.  In  the  same  note,  YPF  communicated  to  the  Operators  of  Areas  “ENARSA  2”  and 
“ENARSA 3” of its decision not to convert the association agreements. 

Resolution No. 14/2015 

On  February 4,  2015,  Resolution  No. 14/2015  was  published  in  the  Official  Gazette,  that  created  the  Crude  Oil  Production  Stimulus  Program 
(Programa de Estímulo a la Producción de Petróleo Crudo) (the “Program”), which was in force from January 1, 2015 through December 31, 2015. 
This Program provided for a payment in Argentine pesos to beneficiary companies, in an amount of up to U.S.$ 3.00 

112 

per barrel when such company’s quarterly production of crude oil was equal to or greater than the base production level under the Program, in addition 
to the compliance with certain other requirements related to the level of activity of the Company as set for Resolution No. 33/2015. The base production 
level under the Program was the total production of crude oil of the beneficiary company for the fourth quarter of 2014. Those beneficiary companies 
that had satisfied the demand of all of the domestic refineries operating within Argentina may direct a portion of their production to the international 
market and receive an additional payment of U.S.$ 2.00 or U.S.$ 3.00 per barrel of crude oil exported, depending on the volume exported. 

The payments would be made in Argentine pesos using the Reference Exchange Rate of BCRA Communication “A” 3,500 of the last business day prior 
to  the  presentation  of  the  information  of  the  corresponding  quarter  to  the  Commission.  See  “Item  5.  Operating  and  Financial  Review  and 
Prospects—Principal Income Statement Line Items—Revenues.” 

MINEM Resolution No. 21/2016 

On  March 11,  2016,  MINEM  Resolution  No. 21/2016  was  published  in  the  Official  Gazette,  which  established  an  export  stimulus  program  of 
crude oil surplus, after satisfying domestic demand for crude oil Escalante from the San Jorge Gulf basin. The stimulus was paid for each shipment to 
the extent that the average price of Brent oil did not exceed U.S.$ 47.50 per barrel two days after the shipment and was valid until December 31, 2016. 
The compensation paid by the Argentine government amounted to U.S.$ 7.50 per barrel as long as the criteria was met. 

Decree No. 442/2016 – Province of Chubut 

On April 11, 2016, Decree No. 442/2016 was published in the Official Gazette of the province of Chubut, which established an export stimulus 
program of crude oil surplus, after satisfying domestic demand. The stimulus was paid for each shipment to the extent that the average price of Brent oil 
did not exceed U.S.$ 47.20 per barrel two days after the shipment and was valid until December 31, 2016. The compensation paid by the province of 
Chubut amounted to U.S.$ 2.50 per barrel as long as the criteria was met. 

MINEM Decree No. 192/2017 

On March 21, 2017, Decree No. 192/2017 was published in the Official Gazette,  which created the “Oil and  its Byproducts Import Operations 
Registry” (the “Registry”), which authority of application is MINEM (through the Secretariat of Hydrocarbon Resources). The Registry involves import 
operations  of:  (i) crude  oil  and (ii) certain  other  specific byproducts  listed  in  section  2  of  the  decree. By means of  this  regulation,  any  company  that 
wishes to perform such import operations was obligated to register such operation in the Registry and to obtain authorization from the MINEM before 
the import takes place. The registration of the operation with the MINEM had to be filed in accordance with a specific proceeding that the MINEM had 
to establish for such purpose. 

According  to  this  decree,  the  MINEM  set  the  methodology  applicable  to  issue  import  authorizations,  which  had  to  be  based  in  the  following 
criteria: (a) lack of crude oil with the same characteristics offered in the domestic market; (b) lack of additional treatment capacity in domestic refineries 
with domestic crude oil; and (c) lack of byproducts listed in section 2 of the decree offered in the domestic market. This regime excludes any import by 
the national electric market administration company (Compañía Administradora del Mercado Mayorista Eléctrico, “CAMMESA”) in order to supply 
power plants with the main purpose of technical supply to the “Inter-connection Argentinean System” (Sistema Argentino de Interconexión or “SADI”). 

Decree  No. 192/2017  was  in  force  until  December 31,  2017,  according  to  Decree  No. 962/2017  (published  in  the  Official  Gazette  on 

November 27, 2017). 

Public Emergency 

On January 6, 2002, the Argentine Congress enacted the Public Emergency Law, which represented a profound change in the economic model 
effective as of that date, and rescinded the Convertibility Law No. 23,928, which had been in effect since 1991 and had pegged the peso to the dollar on 
a one-to-one basis. In addition, the Public Emergency Law granted to the National Executive Office the authority to enact all necessary regulations in 
order  to  overcome  the  economic  crisis  that  Argentina  was  then  facing.  The  situation  of  emergency  declared  by  Law  No. 25,561  has  been  partially 
extended until December 31, 2019 by Law No. 27,345; specifically, with respect to social emergency as established by Law 27,200 (but not with respect 
to economic emergency which expired on December 31, 2017). The National Executive Office is authorized to execute the powers delegated by Law 
No. 25,561 until such date. 

113 

After  the  enactment  of  the  Public  Emergency  Law,  several  other  laws  and  regulations  have  been  enacted  to  overcome  the  economic  crisis, 
including (1) the conversion into pesos of deposit, obligations and tariffs of public services, among others, and (2) the imposition of customs duties on 
the export of hydrocarbons with instructions to the National Executive Office to set the applicable rate thereof. The application of these duties and the 
instruction  to  the  National  Executive  Office  has  been  extended  until  January  2017  by  Law  No. 26,732.  On  January 8,  2017,  export  duties  upon 
hydrocarbon exports established by Law No. 26,732 had ceased to be enforceable; however, export duties to hydrocarbons and its derivatives have been 
reinstated  through  Decree  No. 793/2018,  published  on  September 4,  2018.  See  “Item  3.  Key  Information—Risk  Factors—Risks  Relating  to  Our 
Business—“The implementation of new export duties, other taxes and import regulations could adversely affect our results” and “—Export Taxes.” 

Exploration and Production 

The  Hydrocarbons  Law  establishes  the  basic  legal  framework  for  the  regulation  of  oil  and  gas  exploration  and  production  in  Argentina.  The 
Hydrocarbons Law empowers the National Executive Office to establish a national policy for development of Argentina’s hydrocarbon reserves, with 
the principal purpose of satisfying domestic demand. 

Pursuant to the Hydrocarbons Law, exploration and production of oil and gas is carried out through exploration permits, production concessions, 
exploitation  contracts  or  partnership  agreements.  The  Hydrocarbons  Law  also  permits  surface  reconnaissance  of  territory  not  covered  by  exploration 
permits or production concessions upon authorization of the SGE and/or competent provincial authorities, as established by Law No. 26,197, and with 
permission of the private property owner. Information  obtained as a result of  surface reconnaissance must  be provided to the SGE and/or competent 
provincial authorities, which may not disclose this information for two years without permission of the party who conducted the reconnaissance, except 
in connection with the grant of exploration permits or production concessions. 

Under the Hydrocarbons Law, the federal and/or competent provincial authorities may grant exploration permits after submission of competitive 
bids. Permits were granted to third parties in connection with the deregulation and demonopolization process and permits covering areas in which our 
predecessor company, Yacimientos Petrolíferos Fiscales Sociedad del Estado, was operating at the date of the Privatization Law were granted to us by 
such law. In 1991, the National Executive Office established a program under the Hydrocarbons Law (known as “Plan Argentina”) pursuant to which 
exploration permits were auctioned. The holder of an exploration permit has the exclusive right to perform the operations necessary or appropriate for 
the exploration of oil and gas within the area specified by the permit. Under the Hydrocarbons Law, each exploration permit may cover only unproved 
areas not to exceed 10,000 km2 (15,000 km2 offshore) and may have a term of up to 14 years (17 years for offshore exploration). The 14-year term is 
divided into three basic terms and one extension term. The first basic term is up to four years, the second basic term is up to three years, the third basic 
term is up to two years and the extension term is up to five years. At the expiration of each of the first two basic terms, the acreage covered by the 
permit is reduced, at a minimum, to 50% of the remaining acreage covered by the permit, with the permit holder deciding which portion of the acreage 
to keep. At the expiration of the three basic terms, the permit holder is required to surrender all of the remaining acreage to the Argentine government, 
unless the holder requests an extension term, in which case such grant is limited to 50% of the remaining acreage. Under Law No. 27,007, which applies 
to exploration permits issued on or after October 31, 2014, each exploration permit may have a term of up to 11 years for conventional objectives and 13 
years for unconventional objectives and offshore exploration. The terms are divided into two basic terms and one extension term. The first and second 
basic  terms  are  up  to  three  years  for  conventional  objectives  and  up  to  four  years  for  unconventional  objectives  and  offshore  exploration,  and  the 
extension term is up to five years, so long as the permit holder has complied with its investments and other obligations. At the expiration of the first 
basic term, the permit holder will have the right to continue exploring the entire area for the second basic term so long as it has complied with all its 
obligations under the permit. At the expiration of the second basic term, the permit holder is required to surrender all of the remaining acreage, unless 
the holder requests an extension term, in which case such grant is limited to 50% of the remaining acreage. 

If the holder of an exploration permit discovers commercially exploitable quantities of oil or gas, the holder has the right to obtain an exclusive 
concession  for  the  production  and  development  of  this  oil  and  gas.  The  Hydrocarbons  Law,  as  modified  by  Law  No. 27,007,  provides  that  new 
conventional  oil  and  gas  production  concessions  shall  remain  in  effect  for  25  years  from  the  date  of  the  award  of  the  production  concession,  new 
unconventional  oil  and  gas  production  concessions  shall  remain  in  effect  for  35  years  from  that  date,  and  new  offshore  oil  and  gas  production 
concessions  shall  remain  in  effect  for  30  years  from  that  date,  in  addition  to  any  remaining  exploration  term  at  the  date  of  such  award.  The 
Hydrocarbons Law, as modified by Law No. 27,007, further provides for the concession term to be extended for periods of up to ten additional years 
each, subject to terms and conditions approved by the grantor at the time of the extension. Such conditions may include the payment of an extension 
bond with a maximum amount equal to the result of multiplying the remaining proved reserves at the end of the concession period by 2% of the average 
basin  price,  for  the  period  two  years  prior  to  the  date  the  extension  is  granted,  applicable  to  the  hydrocarbons  at  issue.  Under  Law  No. 26,197,  the 
authority to extend the terms of current and new permits and concessions has been vested in the governments of the provinces in which the relevant 
block  is  located  (and  the  Argentine  government  in  respect  of  offshore  blocks  beyond  12  nautical  miles).  In  order  to  be  entitled  to  the  extension,  a 
concessionaire, such as us, 

114 

must have complied with all of its obligations under the Hydrocarbons Law, including, without limitation, evidence of payment of taxes and royalties 
and compliance with environmental, investment and development obligations, must be producing hydrocarbons in the area at issue and must present an 
investment plan to develop the concession. A production concession also confers on the holder the right to conduct all activities necessary or appropriate 
for the production of oil and gas, provided that such activities do not interfere with the activities of other holders of exploration permits and production 
concessions. A production concession entitles the holder to obtain a transportation concession for the oil and gas produced. See “—Transportation of 
Liquid Hydrocarbons.” 

Exploration permits, and production concessions require holders to carry out all necessary work to find or extract hydrocarbons, using appropriate 

techniques, and to make specified investments. In addition, holders are required to: 

• avoid damage to oil fields and waste of hydrocarbons; 

• adopt adequate measures to avoid accidents and damage to agricultural activities, fishing industry, communications networks and the water table; 

and 

• comply with all applicable federal, provincial and municipal laws and regulations. 

According to  the  Hydrocarbons Law,  holders  of  production concessions,  including us,  are also  required  to pay royalties to  the  province  where 
production occurs. As modified by Law No. 27,007, royalty rates are set at a maximum of 12% (though 3% will be added for each extension up to a 
maximum of 18%). They are payable on the value at the wellhead (equal to the price upon delivery of the product, less transportation, treatment costs 
and other deductions) of crude oil production and natural gas volumes sold. These royalty rates may be reduced taking into account productivity and the 
type of production at issue. Notwithstanding the foregoing, in concessions extended prior to the effectiveness of Law No. 27,007, October 31, 2014, the 
previous conditions remain in force. In some cases, an additional 3% royalty has been added. See “—Main Properties—Argentine Exploration Permits 
and  Exploitation  Concessions.”  In  the  extension  of  our  concessions  in  Santa  Cruz,  we  agreed  to  a  10%  royalty  (instead  of  12%)  for  unconventional 
hydrocarbons. The value is calculated based upon the volume and the sale price of the crude oil and gas produced, less the costs of transportation and 
storage.  In  addition,  pursuant  to  S.E.  Resolution  No. 435/04  issued  by  the  SGE,  if  a  concession  holder  allots  crude  oil  production  for  further 
industrialization  processes  at  its  plants,  the  concession  holder  is  required  to  agree  with  the  provincial  authorities  or  the  SGE,  as  applicable,  on  the 
reference price to be used for purposes of calculating royalties. 

As a result of Resolution No. 394/07 of the Ministry of Economy, among other things, which increased duties on exports of certain hydrocarbons, 
Argentine companies began to negotiate the price for crude oil in the domestic market, which would in turn be used as the basis for the calculation of 
royalties.  In  January  2013,  the  Ministry  of  Economy  issued  Resolution  No. 1/13,  modifying  Exhibit  I  of  Resolution  No. 394/07  of  the  Ministry  of 
Economy, thus setting a new reference price for crude oil (U.S.$ 70 per barrel) and certain products. In October 2014, the Ministry of Economy issued 
Resolution No. 803/2014, incorporating Exhibit III to Resolution No. 394/07 of the Ministry of Economy, thus modifying the applicable percentages of 
duties of exports for certain products below certain prices. 

However,  on  December 29,  2014,  Resolution  No. 1,077/2014  repealed  Resolution  No. 394/07,  as  amended,  and  set  forth  a  new  withholding 
program based on the international price of crude oil (the “International Price”). The International Price was calculated based on the Brent value for the 
applicable  month  less  U.S.$  8  per  barrel.  The  new  program  established  a  1%  general  nominal  withholding  applicable  to  all  products  covered  by  the 
resolution, including crude oil, diesel, gasoline and lubricants as well as other petroleum products, to the extent that the International Price was below 
U.S.$ 71 per barrel. The resolution further provides an increasing variable withholding rate for crude oil exports to the extent the International Price 
exceeds U.S.$ 71 per barrel. As a result, the maximum a producer may charge was approximately U.S.$ 70 per barrel exported, depending on the quality 
of  crude  sold.  The  resolution  also  sets  forth  increasing  withholding  rates  for  exports  of  diesel,  gasoline,  lubricants  and  other  petroleum  when  the 
International Price exceeds U.S.$ 71 per barrel at rates that allow the producer to receive a portion of the elevated price. 

On January 8, 2017, export duties on hydrocarbon exports established by Law No. 26,732 ceased to be enforceable. 

However, on September 3, 2018, customs duties were established on the export of hydrocarbons through Decree No. 793/2018, published in the 
Official Gazette on September 4, 2018. The export tax rate was increased to 12%, with a threshold of Ps. 3 or Ps. 4 per dollar depending on the product. 
In  addition  to  the  above,  the  Public  Emergency  Law,  which  created  the  export  withholdings,  established  that  export  withholdings  were  not  to  be 
deducted from the export price for purposes of calculating the 12% royalties. The royalty expense incurred in Argentina is accounted for as a production 
cost (as explained in “—Exploration and Production—Oil and gas production, production prices and production costs”). According to the Hydrocarbons 
Law, any oil and gas produced by the holder of an exploration permit prior to the grant of a production concession is subject to the payment of a 15% 
royalty. 

115 

Furthermore, pursuant to Sections 57 and 58 of the Hydrocarbons Law, holders of exploration permits and production concessions must pay an 
annual surface fee that is based on acreage of each block and that varies depending on the phase of the operation, such as exploration or production, and 
in  the  case  of  the  former,  depending  on  the  relevant  period  of  the  exploration  permit.  These  amounts  were  updated  by  Law  No. 27,007  and  may  be 
partially  adjusted  as  from  the  second  basic  exploration  period  in  light  of  investments  actually  carried  out.  Exploration  permits,  and  production  or 
transportation concessions may be terminated upon any of the following events: 

•

•

•

•

•

failure to pay annual surface taxes within three months of the due date; 

failure to pay royalties within three months of the due date; 

substantial and unjustifiable failure to comply with specified production, conservation, investment, work or other obligations; 

repeated failure to provide information to, or facilitate inspection by, authorities or to utilize adequate technology in operations; 

in  the  case  of  exploration  permits,  failure  to  apply  for  a  production  concession  within  30  days  of  determining  the  existence  of  commercially 
exploitable quantities of hydrocarbons; 

• bankruptcy of the permit or concession holder; 

• death or end of legal existence of the permit or concession holder; or 

•

failure  to  transport  hydrocarbons  for  third  parties  on  a  non-discriminatory  basis  or  repeated  violation  of  the  authorized  tariffs  for  such 
transportation. 

The Hydrocarbons Law further provides that a cure period, of a duration to be determined by the SGE and/or the competent provincial authorities, 

must be provided to the defaulting concessionaire prior to the termination. 

When  a  production  concession  expires  or  terminates,  all  oil  and  gas  wells,  operating  and  maintenance  equipment  and  facilities  automatically 
revert to the province where the reservoir is located or to the Argentine Republic in the case of reservoirs under federal jurisdiction (for instance, located 
on the continental shelf or beyond 12 nautical miles offshore), without compensation to the holder of the concession. 

Most  of  our  production  concession  expirations  have  been  extended  from  their  original  expiration  dates.  See  “Item  3.  Key  Information—Risk 
Factors—Risks Relating to Our Business—Argentine oil and gas production concessions and exploration permits are subject to certain conditions and 
may  be  cancelled  or  not  renewed.”  The  granting  of  an  extension  is  an  unregulated  process  and  normally  involves  lengthy  negotiations  between  the 
applicant and the relevant government. Although the Hydrocarbons Law, as modified, provides that applications must be submitted at least one year 
prior  to  the  concession  expiration  date,  it  is  industry  practice  to  commence  the  process  far  earlier,  typically  as  soon  as  the  technical  and  economic 
feasibility of new investment projects beyond the concession term become apparent. 

On March 16, 2006, the former Argentine Secretariat of Energy issued S.E. Resolution No. 324/06 requiring that holders of exploration permits 
and hydrocarbon concessions must file with such agency details of their proved reserves existing in each of their areas, certified by an external reserves 
auditor,  each  year.  Holders  of  hydrocarbon  concessions  that  export  hydrocarbons  are  obliged  to  certify  their  oil  and  gas  proved  reserves.  The 
aforementioned  certification  only  has  the  meaning  established  by  S.E.  Resolution  No. 324/06,  according  to  which  it  is  not  to  be  interpreted  as  a 
certification of oil and gas reserves under the SEC rules. See “—Upstream Overview—Oil and Gas Reserves.” On November 7, 2016, MINEM issued 
Resolution No. 69/2016, which included technical modifications to S.E. Resolution No. 324/06 by amending some of its technical annexes regulating 
the  reserves  information  required  to  be  provided.  It  also  established  sanctions  for  hydrocarbon  producers  in  the  case  of  irregularities  in  the  reserves 
reports  filed,  including  admonishment,  suspension  or  cancellation  of  the  Hydrocarbons  Producers  Registry,  depending  on  the  magnitude  of  the 
irregularity. 

In March 2007, the former Argentine Secretariat of Energy issued Resolution No. 407/07 that approved new regulations concerning the Oil and 
Gas Exploration and Production Companies Registry. According to Resolution No. 407/07, YPF, as a holder of production concessions and exploration 
permits,  is  banned  from  hiring  or  in  any  way  benefiting  from  any  company  or  entity  which  is  developing  or  has  developed  oil  and  gas  exploration 
activities within the Argentine continental platform without an authorization from the relevant Argentine authorities. 

116 

In connection with the extension of concessions, see “—Upstream Overview—Main properties.” 

Security Zones Legislation 

Argentine law restricts the ability of non-Argentine companies to own real estate, oil concessions or mineral rights located within, or with respect 

to areas defined as, security zones (principally border areas). 

•

•

Additionally, prior approval of the Argentine government is required: 

for non-Argentine shareholders to acquire control of us; or 

if  and  when  the  majority  of  our  shares  belong  to  non-Argentine  shareholders,  as  was  the  case  when  we  were  controlled  by  Repsol  for  any 
additional  acquisition  of  real  estate,  mineral  rights,  oil  or  other  Argentine  government  concessions  located  within,  or  with  respect  to,  security 
zones. 

Natural Gas Transportation and Distribution 

The  gas  transmission  system  is  currently  divided  into  two  systems  principally  on  a  geographical  basis  (the  northern  and  the  southern  trunk 
pipeline systems), designed to give both systems access to gas sources and to the main centers of demand in and around Buenos Aires. These systems 
are operated by two transportation companies. In addition, the distribution system is divided into nine regional distribution companies, including two 
distribution companies serving the greater Buenos Aires area. 

The regulatory structure for the natural gas industry creates an open-access system, under which gas producers, such as us, will have open access 

to future available capacity on transmission and distribution systems on a non-discriminatory basis. 

Cross-border gas pipelines were built to interconnect Argentina, Chile, Brazil and Uruguay, and producers such as us had been exporting natural 
gas to the Chilean and Brazilian markets, to the extent permitted by the Argentine government. During the last several years the Argentine authorities 
have  adopted  a  number  of  measures  restricting  exports  of  natural  gas  from  Argentina,  including  issuing  domestic  supply  instruction  pursuant  to 
Regulation No. 27/04 and Resolutions No. 265/04, 659/04 and 752/05 (which require exporters to supply natural gas to the Argentine domestic market), 
issuing express instructions to suspend exports, suspending processing of natural gas and adopting restrictions on natural gas exports imposed through 
transportation companies and/or emergency committees created to address crisis situations. However, since 2017 the Argentine authorities have adopted 
a number of measures aiming at allowing companies to resume natural gas exports. See “—Market Regulation— Natural gas export administration and 
domestic supply priorities.” 

Transportation of Liquid Hydrocarbons 

The  Hydrocarbons  Law  permits  the  National  Executive  Office  to  award  35-year  concessions  for  the  transportation  of  oil,  gas  and  petroleum 
products following submission of competitive bids. Pursuant to Law No. 26,197, the relevant provincial governments have the same powers. Holders of 
production  concessions  are  entitled  to  receive  a  transportation  concession  for  the  oil,  gas  and  petroleum  products  that  they  produce.  The  term  of  a 
transportation concession may be extended for an additional ten-year term upon application to the National Executive Office. 

Law  No. 27,007,  which  applies  to  concessions  issued  on  or  after  October  2014  other  than  those  already  governed  by  previous  laws,  for  the 
transportation  of  liquid  hydrocarbons,  permits  the  National  Executive  Office  to  award  concessions  for  the  transportation  of  oil,  gas  and  petroleum 
products for terms equivalent to those granted for production concessions linked to those transport concessions, following submission of competitive 
bids. The term of a transportation concession may be extended for additional terms equivalent to those of the associated production concession. The 
holder of a transportation concession has the right to: 

•

transport oil, gas and petroleum products; and 

• construct and operate oil, gas and products pipelines, storage facilities, pump stations, compressor plants, roads, railways and other facilities and 

equipment necessary for the efficient operation of a pipeline system. 

117 

The  holder  of  a  transportation  concession  is  obligated  to  transport  hydrocarbons  for  third  parties  on  a  non-discriminatory  basis  for  a  fee.  This 
obligation,  however,  applies  to  producers  of  oil  or  gas  only  to  the  extent  that  the  concession  holder  has  surplus  capacity  available  and  is  expressly 
subordinated to the transportation requirements of the holder of the concession. Transportation tariffs are subject to approval by the SGE for oil and 
petroleum  pipelines  and  by  ENARGAS  for  gas  pipelines.  Upon  expiration  of  a  transportation  concession,  the  pipelines  and  related  facilities 
automatically revert to the Argentine government without payment to the holder. The Privatization Law granted us a 35-year transportation concession 
with respect to the pipelines operated by Yacimientos Petrolíferos Fiscales Sociedad del Estado at the time. Gas pipelines and distribution systems sold 
in connection with the privatization of Gas del Estado are subject to a different regime as described above. 

Additionally,  pursuant  to  Law  No. 26,197,  all  transportation  concessions  located  entirely  within  a  province’s  jurisdiction  and  not  directly 
connected  to  any  export  pipeline  are  to  be  transferred  to  such  province.  The National  Executive  Office  retains  the  power  to  regulate  and  enforce  all 
transportation concessions located within two or more provinces and all transportation concessions directly connected to export pipelines. 

Refining 

Crude oil refining activities conducted by oil producers or others are subject to prior registration of oil companies in the registry maintained by the 
SGE  and  compliance  with  safety  and  environmental  regulations,  as  well  as  to  provincial  environmental  legislation  and  municipal  health  and  safety 
inspections. 

In  January  2008,  the  Argentine  Secretariat  of  Domestic  Commerce  issued  Resolution  No. 14/2008,  whereby  the  refining  companies  were 

instructed to optimize their production in order to obtain maximum volumes according to their capacity. 

Executive Decree No. 2,014/08 of November 25, 2008, created the “Refining Plus” program to encourage the production of diesel and gasoline. 
The former Argentine Secretariat of Energy, by S.E. Resolution No. 1,312/08 of December 1, 2008, approved the regulations of the program. Pursuant 
to this program, refining companies that undertook the construction of a new refinery or the expansion of their refining and/or conversion capacity, and 
whose  plans  were  approved  by  the  former  Argentine  Secretariat  of  Energy,  were  entitled  to  receive  export  duty  credits  to  be  applied  to  exports  of 
products within the scope of Resolution No. 394/07 and Resolution No. 127/08 (Annex) issued by the Ministry of Economy. In February 2012, by Notes 
No. 707/12  and  800/12  (the  “Notes”)  of  the  former  Argentine  Secretariat  of  Energy,  YPF  was  notified  that  the  benefits  granted  under  the  “Refining 
Plus” program had been temporarily suspended. The effects of the suspension extend to benefits accrued and not yet redeemed by YPF at the time of the 
issuance of the Notes. The reasons alleged for such suspension were that the “Refining Plus” program had been created in a context where domestic 
prices were lower than prevailing prices and that the objectives sought by the program had already been achieved. On March 16, 2012. YPF filed an 
administrative complaint against the temporary suspension. As of the date of this annual report, YPF has partially collected the compensation expected 
according to the Program. 

Market Regulation 

Overview 

Under the Hydrocarbons Law and the applicable Decrees, holders of production concessions, such as us, have the right to produce and own the oil 

and gas they extract and are allowed to sell such production in the domestic or export markets, in each case subject to the conditions described below. 

The Hydrocarbons Law authorizes the National Executive Office to regulate the Argentine oil and gas markets and prohibits the export of crude 
oil during any period in which the National Executive Office finds domestic production to be insufficient to satisfy domestic demand. If the National 
Executive  Office  restricts  the  export  of  crude  oil  and  petroleum  products  or  the  sale  of  natural  gas,  the  applicable  Decrees  provide  that  producers, 
refiners and exporters shall receive a price for the crude oil and petroleum products, not lower than that of imported crude oil and petroleum products of 
similar quality. 

Furthermore,  the  applicable  Decrees  required  the  National  Executive  Office  to  give  twelve  months’  notice  of  any  future  export  restrictions. 
Notwithstanding  the  above  provisions,  certain  subsequently-enacted  resolutions  (S.E.  Resolution  No. 1,679/04,  S.E.  Resolution  No. 532/04  and 
Resolution No. 394/07 of the Ministry of Economy and Production) have modified the aforementioned price mechanism, resulting, in certain cases, in 
prices to producers that are below the levels described above.

In addition, in May 2012, the Expropriation Law was passed by the Argentine Congress and became effective. See “—The Expropriation Law” 

and “—Decree No. 1,277/2012” and “—Decree No. 272/2015.” 

On  July 15,  2013,  Decree  No. 929/2013  was  published  in  the  Official  Gazette,  which  provides  for  the  creation  of  an  Investment  Promotion 
Regime for the Exploitation of Hydrocarbons (the “Promotion Regime”), both for conventional and unconventional hydrocarbons to be applied across 
the Argentine territory. Applications to be included in this Promotion Regime may be filed by subjects duly registered with the National Registry of 
Hydrocarbon Investments who are holders of exploration permits and/or exploitation concessions and/or third parties associated with those holders and 
who  submit  an  Investment  Project  for  Hydrocarbon  Exploitation  (the  “Investment  Project”)  to  the  Commission  created  by  Decree  No. 1,277/12, 
entailing a direct investment in foreign currency of at least U.S.$ 1 billion, calculated at the time of submission of the Investment Project, and to be 
invested in the first five years of the Investment Project. Beneficiaries of this Promotion Regime shall enjoy the following benefits, among others: i) 
they  shall  be  entitled,  under  the  terms  of  the  Hydrocarbons  Law,  from  the  fifth  anniversary  of  the  start-up  of  their  respective  Investment  Project,  to 
freely export 20% of the production of liquid and gaseous hydrocarbons produced under such Investment Projects, at a 0% export tax rate, if applicable; 
ii)  they  shall  freely  dispose  of  100%  of  the  proceeds  derived  from  the  export  of  the  hydrocarbons  mentioned  in  i)  above,  provided  the  approved 
Investment Project would have generated an inflow of foreign currency into Argentina’s financial market equal to at least U.S.$ 1 billion, following the 
requirements mentioned above; iii) if hydrocarbon production in Argentina is not enough to cover domestic supply needs in accordance with section 6 
of the Hydrocarbons Law, beneficiaries of the Promotion Regime, from the fifth anniversary of the start-up of their respective Investment Projects, shall 
be entitled to obtain, in relation to the aforementioned exportable rate of liquid and gaseous hydrocarbons produced in the Investment Projects, a price 
not lower than the reference export price calculated without deducting any export duties that would have been applicable. Law No. 27,007, as described 
above,  has  incorporated  into  this  regime  projects  submitted  to  the  Commission  entailing  a  direct  investment  in  foreign  currency  of  at  least  U.S.$ 
250 million, calculated at the time of submission of the Investment Project, and to be invested in the first three years of the Investment Project. Further, 
Law No. 27,007 modifies the percentages of hydrocarbons to be benefitted under this regime to 20% of the production of conventional, unconventional 
and offshore concessions at depths less than or equal to 90 meters and 60% of the production of offshore concessions at depths greater than 90 meters. 
See “—Law No. 27,007 (amendment of the Hydrocarbons Law)” and “—Decree No. 272/2015.” 

Additionally,  the  decree  discussed  above  created a  new type of  concession  for  the “Exploitation of  Unconventional  Hydrocarbons,” which  has 
been  incorporated  into  the  Hydrocarbons  Law  by  Law  No. 27,007,  consisting  of  the  extraction  of  liquid  and/or  gaseous  hydrocarbons  through 
unconventional  stimulation  techniques  applied  to  reservoirs  located  in  geological  formations  of  schist  and  slates  (shale  gas  or  shale  oil),  tight  sands 
(tight oil and tight gas), coal layers (coal bed methane) and, in general, from any reservoir that presents low-permeability rock as its main feature. The 
Decree provides that holders of exploration permits and/or exploitation concessions that are beneficiaries of the Promotion Regime shall be entitled to 
apply  for  a  “Concession  for  Unconventional  Hydrocarbons  Exploitation.”  Likewise,  holders  of  a  Concession  for  Unconventional  Hydrocarbons 
Exploitation  who  are  also  holders  of  an  adjacent  and  pre-existing  concession  may  request  the  unification  of  both  areas  into  a  single  unconventional 
exploitation concession, provided the geological continuity of such areas is duly proven. 

As noted above, Law No. 27,007 provides for contributions by companies to the provinces where the projects take place, which amount to 2.5% 
of  the  initial  investment  amount  of  the  project,  to  be  directed  to  “Corporate  Social  Responsibility”  contributions.  In  addition,  an  amount  to  be 
determined by the Commission in light of the extent of the project, to finance infrastructure, have to be contributed by the Argentine Republic. Finally, 
Law  No. 27,007  establishes  that  capital  goods  and  inputs  that  are  essential  to  the  execution  of  the  investment  plans  of  companies  registered  in  the 
National  Registry  of  Hydrocarbon  Investments  shall  pay  import  duties  indicated  in  Decree  No. 927/13  (reduced  rates).  This  list  may  be  extended  to 
other strategic products. 

Production of crude oil and reserves 

Executive Decree No. 2,014/08 of November 25, 2008, created the “Petroleum Plus” program to encourage the production of crude oil and the 
increase  of  reserves  through  new  investments  in  exploration  and  development.  The  former  Argentine  Secretariat  of  Energy,  through  S.E.  Resolution 
No. 1,312/08  of  December 1,  2008,  approved  the  regulations  of  the  program.  The  program  entitled  production  companies  which  increased  their 
production  and  reserves  within  the  scope  of  the  program,  and  whose  plans  were  approved  by  the  former  Argentine  Secretariat  of  Energy,  to  receive 
export duty credits to be applied to exports of products within the scope of Resolution No. 394/07 and Resolution No. 127/08 (Annex) issued by the 
Ministry of Economy. In February 2012, YPF was notified by the former Argentine Secretariat of Energy that the benefits granted under the “Petroleum 
Plus” program had been temporarily suspended. The effects of the suspension extend to benefits accrued and not yet redeemed by YPF at the time of the 
issuance  of  the  notice.  The  reasons  stated  for  the  suspension  were  that  the  “Petroleum  Plus”  program  had  been  created  in  a  context  where  domestic 
prices were lower than prevailing prices and that the objectives sought by the program had already been achieved. On March 16, 2012, YPF filed and 
administrative  complaint  against  the  temporary  suspension.  Executive  Decree  No. 1,330/2015  of  July 13,  2015  provided  for  the  termination  of  the 
“Petroleum  Plus”  program,  establishing  compensation  in  BONAR  2024  Argentine  public  bonds.  As  of  the  date  of  this  report,  YPF  has  not  been 
compensated for the benefits accrued and not yet redeemed by YPF.

Refined products 

In April 2002, the Argentine government and the main oil companies in Argentina, including us, reached an agreement on a subsidy provided by 
the Argentine government to public bus transportation companies. The Agreement on Stability of Supply of Diesel was approved by Executive Decree 
No. 652/02 and assured the transportation companies their necessary supply of diesel at a fixed price of Ps. 0.75 per liter from April 22, 2002 to July 31, 
2002. Additionally, it established that the oil companies are to be compensated for the difference between this fixed price and the market price through 
export  duty  credits.  Subsequent  agreements  entered  into  between  the  Argentine  government  and  the  main  oil  companies  in  Argentina  extended  the 
subsidy scheme until December 2009, while the aforementioned fixed price was revised from time to time. 

In  March  2009,  Executive  Decree  No. 1,390/09  empowered  the  Chief  of  Staff  to  sign  annual  agreements  extending  the  diesel  subsidy  to 
transportation companies for the fiscal year 2009 and until the end of the public emergency declared by the Public Emergency Law and its amendments, 
and instructed such official to incorporate the necessary modifications in order to extend the possibility to compensate with export duty credits on all 
hydrocarbon products currently exported, or with cash. As of the date of this annual report, execution of the annual agreements for the fiscal years 2010 
and 2011 is pending. Nevertheless, the subsidy scheme has continued to be in place on the basis of the monthly communications issued by the Argentine 
Secretariat of Transport notifying oil companies of the volumes to be delivered to each beneficiary of the scheme at the fixed price, and the Argentine 
government has continued to compensate oil companies for deliveries of diesel made under the scheme. 

The former Argentine Secretariat of Energy has issued a series of resolutions in order to provide the market with information about liquid fuel 
prices  and  volumes.  For  example,  S.E.  Resolution  No. 1,102/04  created  the  Registry  of  Liquid  Fuels  Supply  Points,  Self-Consumption,  Storage, 
Distributors  and  Bulk  Sellers  of  Fuels  and  Hydrocarbons,  and  of  Compressed  Natural  Gas;  S.E.  Resolution  No. 1,104/04  created  a  bulk  sales  price 
information  module  as  an  integral  part  of  the  federal  fuel  information  system,  as  well  as  a  mechanism  for  communication  of  volumes  sold.  S.E. 
Resolution  No. 1,834/05  compels  service  stations  and/or  supply  point  operators  and/or  self-consumption  of  liquid  fuels  and  hydrocarbons  who  have 
requested  supply,  and  have  not  been  supplied,  to  communicate  such  situation  to  the  former  Argentine  Secretariat  of  Energy.  S.E.  Resolution 
No. 1,879/05 established that refining companies registered by the former Argentine Secretariat of Energy, who are parties to contracts that create any 
degree of exclusivity between the refining company and the fuel seller, shall assure continuous, reliable, regular and non-discriminatory supply to its 
counterparties, giving the right to the seller to obtain the product from a different source, and thereupon, charging any applicable cost overruns to the 
refining company. 

Disposition  S.S.C.  No. 157/06  of  the  Undersecretariat  of  Fuels  provides  that  fuel  sellers  who  are  parties  to  contracts  that  create  any  degree  of 
exclusivity  between  the  refining  company  and  the  fuel  seller,  and  which  for  any  reason  are  seeking  to  terminate  such  contract,  shall  report  the 
termination in advance with the Undersecretariat of Fuels in order to inform the Argentine Secretariat of Domestic Commerce of the situation. In that 
case, the Argentine Secretariat of Domestic Commerce is to: (i) issue a statement regarding the validity of the termination of the contract and (ii) use all 
necessary means to allow the fuel seller terminating the contract to execute another agreement with a refining company and/or fuel broker in order to 
guarantee its fuel supply. The Disposition has not been imposed by the authorities in cases involving YPF. 

S.E.  Resolution  No. 1,679/04  reinstated  the  registry  of  diesel  and  crude  oil  export  transactions  created  by  Executive  Decree  No. 645/02,  and 
mandated that producers, sellers, refining companies and any other market agent that wishes to export diesel or crude oil to register such transaction and 
to demonstrate that domestic demand has been satisfied and that they have offered the product to be exported to the domestic market. In addition, S.E. 
Resolution No. 1,338/06 added other petroleum products to the registration regime created by Executive Decree No. 645/02, including gasoline, fuel oil 
and  its  derivatives,  aviation  fuel,  coke  coal,  asphalts,  certain  petrochemicals  and  certain  lubricants.  Resolution  No. 715/07  of  the  former  Argentine 
Secretariat of Energy empowered the National Refining and Marketing Direction to determine the amounts of diesel to be imported by each company, in 
specific periods of the year, to compensate exports of products included under the regime of Resolution No. 1,679/04; the fulfillment of this obligation 
to  import  diesel  is  necessary  to  obtain  authorization  to  export  the  products  included  under  Decree  No. 645/02  (crude,  fuel  oil,  diesel,  coke  coal  and 
gasoline, among others). In addition, Resolution No. 25/06 of the Argentine Secretariat of Domestic Commerce, issued within the framework of Law 
No. 20,680, imposes on each Argentine refining company the obligation to supply all reasonable diesel demand, by supplying certain minimum volumes 
(established pursuant to the resolution) to their usual customers, mainly service station operators and distributors. YPF has duly fulfilled its obligation 
under this Resolution and has not received any type of sanction from the authorities in this regard. 

On August 17, 2010, the Argentine Secretariat of Domestic Commerce issued Resolution No. 295/10, imposing that the trade price of liquid fuels 
should  be  rolled  back  to  those  prices  prevailing  on  July 31,  2010.  This  resolution  has  been  successfully  challenged  by  another  company  and  a 
preliminary injunction was granted suspending the effectiveness of such Resolution. This Resolution was later on repealed by Resolution No. 543/10 of 
the Argentine Secretariat of Domestic Commerce. 

120 

On February 2, 2011, the Argentine Secretariat of Domestic Commerce issued Resolution No. 13/11 stating that the retail price of liquid fuels had 
to  be  rolled  back  to  those  prices  prevailing  on  January 28,  2011.  This  resolution  also  required  refineries  and  oil  companies  to  continue  to  supply 
amounts of fuel to the domestic market consistent with amounts supplied the prior year, as adjusted for the positive correlation between the increase in 
the  demand  of  fuel  and  gross  domestic  product.  On  March 29,  2011,  however,  the  Argentine  Secretariat  of  Domestic  Commerce  issued  Resolution 
No. 46/11, which repealed Resolution No. 13/11, alleging that market conditions had changed since its issuance. 

On  April 10,  2013,  Resolution  No. 35/2013  of  the  Argentine  Secretariat  of  Domestic  Commerce,  determined  a  price  cap  for  fuel  at  all  service 
stations for period of six months, which shall not exceed the highest outstanding price as of April 9, 2013 in each of the regions identified of the Annex 
of the Resolution. 

The above resolutions affecting domestic prices expired on November 24, 2013 and are no longer in effect. 

In addition, in May 2012, the Expropriation Law was enacted by the Argentine Congress and became effective. See “—The Expropriation Law” 

and “—Decree No. 1,277/2012.” 

On  December 30,  2013,  the  Commission  approved,  through  Resolution  No. 99/2013,  the  general  rules  for  the  grant  of  quotes  of  liquid  fuels 
volumes  allowed  to  be  imported  by  locally  registered  companies,  including,  among  others,  oil  companies  registered  in  the  relevant  registries  of  the 
Secretariat  of  Energy.  These  rules  regulate  the  requirements,  grant  of  volumes  to  be  imported  and  other  conditions  to  be  complied  with  by  the 
companies  that  wish  to  import  liquid  fuels  free  of  the  tax  on  liquid  fuels  (imposed  by  Law  No. 23,966)  and  the  tax  on  diesel  (imposed  by  Law 
No. 26,098), jointly with other fuels up to a maximum aggregate amount of 7 mmcm. 

The  Secretariat  of  Hydrocarbon  Resources  from  MINEM  approved  Resolution  No. 5/2016  on  May 31,  2016,  replacing  Annex  II  of  Resolution 
No. 1,283/2006,  which  previously  established  specifications  for  Argentina’s  two  grades  of  gasoline,  naphtha  grades  2  and  3.  The  resolution’s  new 
Annex includes modifications to the content of lead, manganese, oxygen and ethanol and, most significantly, sulfur, and requires oil and gas companies 
to implement a plan to lower sulfur limits to 50mg/kg for grade 2 gasoline, 10mg/kg for grade 3 gasoline, and to 350 mg/kg for diesel between 2019 and 
2022. Oil and gas companies must file with the Secretariat of Hydrocarbon Resources a detailed timeline of the program of investments for the next four 
years, to reach the goals provided in Annex I. From June 1, 2016, the sulfur limit for fuel oil will be 7,000 mg/kg. Local refineries producing fuel oil 
that does not fulfill the above mentioned specifications must present to the Secretariat of Hydrocarbon Resources a remediation plan that includes steps 
and actions to fulfill the maximum limit of sulfur within 24 months. Based on the above, YPF has undertaken several studies in respect of investment 
configurations and estimations, under the advice of main technological experts in the field in order to adapt its industrial networking units according to 
the parameters required by the regulation. In October 2016, YPF submitted to the MINEM the following information: a) an investment plan towards 
2019  containing  detailed  information  about  projects  and  terms  necessary  to  fulfill  the  new  quality  specification  of  products  required  by  Resolution 
No. 5/2016; and b) an evaluation of the necessary terms in order to develop the configuration of studies, as discussed in the previous sentence. Once 
those studies, together with their economic impact, are completed, YPF will obtain internal approval from its Board of Directors and then submit to the 
MINEM its investment program towards 2022 to fulfill additional quality requirements established by Resolution No. 5/2016. 

Agricultural Commodity Export Tax Changes 

By Executive Decree No. 133/2015, published in the Official Gazette on December 17, 2015, the Argentine government reduced the export tax on 
soybeans and soybean byproducts by 5% to 30% and eliminated the export taxes on all other commodities. Agricultural commodities with a new 0% 
export tax include meat products, grains, fruits, and vegetables, among other products. In addition, through Executive Decree No. 1343/2016, published 
in  the  Official  Gazette  on  December 30,  2016,  the  Argentine  government  established  that,  beginning  January  2018,  the  soybean  export  tax  will  be 
reduced by 0.5 % each month until December 2019. However, said monthly reduction applied until the adoption of Executive Decree No. 793/2018. See 
“Export Taxes.” 

Finally, by Joint Resolutions Nos. 4/2015 and 7/2015 of the Ministries of Agroindustry, Treasury and Public Finance and Production published in 
the Official Gazette on December 29, 2015, the export permits known as “ROEs” were eliminated and replaced by the registration of a Sworn Affidavit 
of Exports Sales, known as a “DJVE”. 

121 

Automatic and Non-Automatic Import Licenses 

On December 23, 2015, the Ministry of Production published Resolution No. 5/2015, in the Official Gazette, which reinstated the automatic and 
non-automatic import licenses (“LAI” and “LNA,” respectively). In  2013, the former Ministry of Economy and Public Finance eliminated the LNA, 
stating that it existed alongside the Anticipated Import Affidavit (Declaración Jurada Anticipada de Importación) requirement implemented in February 
2012, which was recently repealed by AFIP (Administración Federal de Ingresos Públicos) Resolution No. 3823. 

Resolution No. 5/2015 also established that importers of products included in the Mercosur Tariff Code must obtain a LAI prior to the entrance of the 
product into Argentina. 

Certain products which are listed in Annexes II to XVII of Resolution No. 5/2015 will be subject to an LNA. The LNA will be applicable to a wide 
variety of products, including, but not limited to, textile, footwear, toys, domestic appliances, motorbikes, and automobile parts. 

In order to obtain the LNA, importers must submit certain information from the importer itself (name, tax identification number) and the product (FOB 
value, type and quantity, commercial brand, model, country of origin and of shipping, etc.) through the Integral Import Monitoring System (Sistema 
Integral  de  Monitoreo  de  Importaciones)  (“SIMI”)  created  by  AFIP  Resolution No. 3,823.  After  submitting  this  information,  importers  will  have  ten 
business days to complete certain additional information required by Resolution No. 5/2015. If the ten-day term expires, the SIMI declaration will be 
automatically cancelled. 

Regarding the LNA, Resolution No. 5/2015 establishes that, at any stage of the process, importers may be required to submit additional information or 
documents of the product subject to the LNA and request verification of technical agencies, as applicable. 

Import licenses will be valid for 90 calendar days, once approved by the SIMI. 

The following imports are exempt from the import regime established by Resolution No. 5/2015: 

•

•

•

•

•

•

•

Donation regime. 

Sample regime. 

Diplomatic exemption regime. 

Import of products with duties and tax exemption. 

Import of products from Special Custom Zone (Tierra del Fuego, Antártida and Islas del Atlántico Sur). 

Import of products by the General Secretary of National Executive Office (Secretaria General de la Presidencia de la Nación). 

Courier and mail delivery, only for importer private use or consumption. 

Resolution  No. 5/2015  became  effective  on  December 24,  2015,  and  the  Secretariat  of  Trade  was  the  application  authority,  and  was  derogated  by 
Resolution N° 292/2017 published in the Official Gazette on July 7, 2017. 

Resolution No. 523- E/2017 from the Ministry of Production established a new import licensing regime that will still require importers of a broad 

range of products to obtain an import license prior to importation. 

According to the new Resolution No. 523-E/2017, imports into Argentina must obtain an automatic import license except for a range of items that 
will need  to obtain a non-automatic license.  Automatic licenses  will be processed through the SIMI) after  the importer provides certain  information, 
including its name and tax identification number, the FOB value of the product, tariff classification, type and quantity, brand, model, version, state of 
the goods, country of origin and country of provenance. 

Importers  wishing  to  obtain  a  non-automatic  import  license  must  be  duly  registered  in  the  Ministry  of  Production  Single  Registry  (R.U.M.P.), 
provide  the  aforementioned  information,  and  provide  within  10  (ten)  working  days  from  the  date  the  procedure  was  formalized  and  viewed  certain 
additional information that may include, among other things, the name and address of the exporter and 

122 

more detailed information on the goods to be imported as well as any applicable standards or certification requirements. In the case of covered travel 
goods and textile, apparel and footwear products (as well as certain other items), information must also be provided on the composition of the product. If 
the required information is not provided within 10 (ten) working days, the request for the non-automatic import license will be cancelled. 

Decree No. 629/2017 

Decree No. 629/2017—published in August 10, 2017 in the Official Gazette—introduces a “Regime for the Import of Used Good for the Oil & Gas 
Industry” (the “Regime”), that admits definitive import of used goods not older than 10 years since fabrication. 

The Regime establishes an import rate ranging between 0% and 14% for goods included in the duty positions included in the annexes to the Decree. 

Both the company registered under the Registry of Oil Companies and the company providing services directly to the oil and gas industry may apply for 
the benefit. 

The Regime will be in force from August 11, 2017 until June 30, 2019. 

Natural gas 

In  January  2004,  Executive  Decree  No. 180/04  (i)  created  the  Electronic  Gas  Market  (“MEG”)  for  the  trade  of  daily  spot  sales  of  gas  and  a 
secondary market of transportation and distribution services, and (ii) established information obligations for buyers and sellers of natural gas in relation 
to  their  respective  commercial operations,  required  as  a  condition  to  be  authorized  to  inject into  and  transport through  the  transportation  system  any 
volume  of  natural  gas  (further  regulated  by  Resolution  No. 1,146/04  issued  on  November 9,  2004  and  Resolution  No. 882/05  issued  by  the  former 
Argentine Secretariat of Energy). According to Executive Decree No. 180/04, all daily spot sales of natural gas must be traded within the MEG. 

In January 2004, Executive Decree No. 181/04 authorized the former Argentine Secretariat of Energy to negotiate with natural gas producers a 
pricing  mechanism  for  natural  gas  supplied  to  industries  and  electric  generation  companies.  Domestic  market  prices  at  the  retail  market  level  were 
excluded from these negotiations. 

On  June 14,  2007,  Resolution  No. 599/07  of  the  former  Argentine  Secretariat  of  Energy  approved  a  proposed  agreement  with  natural  gas 
producers  regarding  the  supply  of  natural  gas  to  the  domestic  market  during  the  period  2007  through  2011  (“Agreement  2007-2011”).  We  executed 
Agreement 2007-2011 taking into account that producers that did not enter into Agreement 2007-2011 would be required to satisfy domestic demand 
before  those  who  entered  into  Agreement  2007-2011.  The  purpose  of  Agreement  2007-2011  was  to  guarantee  the  supply  of  the  domestic  market 
demand at the levels registered in 2006, plus the growth in demand by residential and small commercial customers. However, we expressly stated that 
the execution of Agreement 2007-2011 did not entail any recognition by us of the validity of the terms and conditions of the various resolutions of the 
former Argentine Secretariat of Energy establishing programs for the curtailment or re-routing of exports to satisfy domestic demand. We challenged 
Resolution No. 599/07 and stated that we signed Agreement 2007-2011 taking into account the potential consequences of not doing so. 

The former Argentine Secretariat  of Energy created,  through Resolution No. 24/08 issued on March 13, 2008, a program named “Gas Plus” to 
encourage natural gas production resulting from discoveries, new fields and tight gas, among other factors. The natural gas produced under the Gas Plus 
program is not subject to Agreement 2007-2011 and the price conditions established under such agreement. 

The  former  Argentine  Secretariat  of  Energy,  through  Resolution  No. 1031/08  issued  on  September 12,  2008,  modified  Resolution  No. 24/08, 
establishing the specific  conditions petitioners  must  meet  in  order  to  qualify for  the Gas Plus  program.  Certain  of such conditions  were  modified by 
Resolution No. 695/09 of the former Argentine Secretariat of Energy, which demands compliance with commitments already assumed. 

The former Argentine Secretariat of Energy, through Resolution No. 1070/08 issued on October 1, 2008, ratified the complementary agreement 
entered  into  between  Argentine  natural  gas  producers  and  the  former  Argentine  Secretariat  of  Energy  on  September 19,  2008  (the  “Complementary 
Agreement”), which (i) modified gas prices at the wellhead and segmented the residential sector in terms of natural gas demand, and (ii) established the 
requirement that natural gas producers contribute to the fiduciary fund created by Law No. 26,020. The Complementary Agreement also contains certain 
requirements  concerning  the  provision  of  LPG  to  the  domestic  market.  See  “—Liquefied  petroleum  gas.”  Through  Resolution  No. 1,417/08,  the 
Secretariat of Energy determined the basin prices for the residential 

123 

segment applicable to the producers that signed the Complementary Agreement. On January 13, 2010, the natural gas producers signed an addendum to 
the  Complementary  Agreement  which  extended  the  commitment  to  contribute  to  the  fiduciary  funds  created  by  Law  No. 26,020  until  December 31, 
2010. On January 25, 2011, the natural gas producers signed a second addendum to the Complementary Agreement which extended such commitment 
until December 31, 2011. 

On  March 19,  2012,  S.E.  Resolution  No. 55/2012  of  the  Secretariat  of  Energy  was  published  in  the  Official  Gazette,  which  extended  the 
Complementary Agreement for 2012 and established the following with respect to non-signing parties: (i) the natural gas price increase established by 
the  Complementary  Agreement  will  not  be  applicable  to  natural  gas  injected  into  the  gas  system  by  non-signing  parties;  (ii) natural  gas  injected  by 
non-signing parties will be consumed first in the order of priority by residential users, which has the lowest tariffs; and (iii) non-signing parties must 
fulfill all of the commitments undertaken by natural gas producers under Agreement 2007-2011, which was extended by Resolution S.E. No. 172. On 
March 23,  2012,  S.E.  Resolution  No. 55/2012  was  supplemented  by  ENARGAS  Resolution  No. 2087/2012,  which  sets  forth,  among  others,  the 
procedure that distribution companies should follow to secure amounts to be deposited with the fiduciary fund created by Law No. 26,020. Additionally, 
according to this resolution, producers that have not signed the 2012 extension of the Complementary Agreement are not allowed to charge the wellhead 
price increases for gas set forth in S.E. Resolutions No. 1,070/2008 and 1417/2008 to consumers directly supplied by distribution companies. Thus, such 
non-signing  producers  have  to  invoice  the  lower  prices  which  were  in  effect  prior  to  the  adoption  of  these  resolutions  for  the  gas  supplied  to  the 
distribution companies. 

Thereafter,  on  April 19,  2012,  December 18,  2012  and  December 19,  2013,  YPF  signed  the  2012,  2013  and  2014  extensions  of  the 

Complementary Agreement, respectively. The dispatch mechanism for natural gas was regulated further by Resolution No. 1,410, as explained below. 

Executive Decree No. 2067/08 of December 3, 2008, created a fiduciary fund to finance natural gas imports destined for injection into the national 
pipeline system, when required to satisfy the internal demand. The fiduciary fund is funded through the following mechanisms: (i) various tariff charges 
which are paid by users of regular transport and distribution services, gas consumers that receive gas directly from producers and companies that process 
natural gas; (ii) special credit programs that may be arranged with domestic or international organizations; and (iii) specific contributions assessed by 
the  former  Argentine  Secretariat  of  Energy  on  participants  in  the  natural  gas  industry.  This  decree  has  been  subject  to  different  judicial  claims  and 
judges  throughout  the  country  have  issued  precautionary  measures  suspending  its  effects.  On  November 8,  2009,  ENARGAS  published  Resolution 
No. 1,982/11, which supplements Decree No. 2067/08. This Resolution adjusts the tariff charges established by Executive Decree No. 2,067/08 to be 
paid by users in the residential segment and gas processing and electric power companies, among others, starting December 1, 2011. On November 24, 
2011, ENARGAS issued Resolution No. 1,991/11, which extends the type of users that will be required to pay tariff charges. YPF has challenged these 
resolutions.  On  April 13,  2012,  a  precautionary  measure  was  granted  regarding  the  processing  plant  El  Porton,  suspending  the  effects  of  these 
resolutions with respect to such plant. 

On  November 5,  2012,  Law  No. 26,784  was  published  in  the  Official  Gazette,  which  approved  the  National  Administration  Budget  for  2013. 
Article 54 of the Law established that the tariff charges and the fiduciary fund established by Executive Decree No. 2,067/08 and all its supplementary 
acts, shall be ruled by Law No. 26,095. 

Through Resolution No. 28/2016, published on April 1, 2016, MINEM declared that all acts which determined the imposition of the tariff charge 

ceased to be effective and instructed ENARGAS to adopt measures to cease invoicing the tariff charge. 

In April 2018 and with respect to tariff charge “Decree No. 2,067/08”, the Federal Administrative Court of Appeals No. 11 delivered judgement in 
favor  of  Mega  (for  the  period  subsequent  to  the  adoption  of  the  2013  Budget  Law  No. 26,784),  declaring  Articles  53  and  54  of  such  law 
unconstitutional, with regards to Mega. The judgment is final since it was not appealed by the Argentine Government. 

On  July 17,  2009,  the  Ministry  of  Federal  Planning  and  certain  natural  gas  producers  (including  YPF)  signed  an  agreement  which  sets  forth: 
(i) natural gas prices at the wellhead for the electric power generators segment from July to December 2009, and (ii) amounts to be received by natural 
gas  producers  for  volumes  sold  to  the  residential  segment  from  August  2009  onwards.  These  amounts  are  adjusted  on  a  monthly  basis  so  that  they 
represent 50% of the amount collected by the fiduciary fund to finance natural gas imports. 

124 

On  October 4,  2010,  ENARGAS  Resolution  No. 1,410/10,  was  published  in  the  Official  Gazette,  which  set  forth  new  rules  for  natural  gas 
dispatch applicable to all participants in the gas industry and imposing the following new and more severe priority demand gas restrictions on producers: 

• Distributors remain able to solicit all the gas necessary to cover the priority demand despite such gas volumes’ exceeding those that the former 
Argentine Secretariat of Energy would have allocated by virtue of Agreement 2007-2011 ratified by the Resolution No. 599/07. See “—Gas and 
Power—Delivery commitments.” 

• Producers are obligated to confirm all the natural gas requested by distributors in respect of the priority demand. The producers’ portion of such 
volumes  follows  the  allocation  criterion  established  by  the  Resolution  No. 599/07.  We  cannot  predict  the  amount  of  the  estimated  domestic 
demand that a producer may be required to satisfy, regardless of whether such producer signed Agreement 2007-2011. 

• Once the priority demand has been satisfied, the remaining demands are fulfilled, with exports last in order of priority. 

•

In the event a producer is unable to meet the requested demand, transporters are responsible for redirecting gas until a distributor’s gas demand is 
met. The gas deficiency is either (i) deducted from the producer suffering the deficiency if it is able to meet the demands of its other clients in the 
same basin or (ii) recuperated from the remainder of the gas producers in the event the deficient producer is not able to serve any of its clients in 
the same basin. 

As a result, this regime imposes a jointly liable supply obligation on all producers in the event any producer experiences a gas supply deficiency. 

We have challenged the validity of the aforementioned regulation. On December 9, 2015, ENARGAS denied our administrative appeal. 

On  December 17,  2010  certain  natural  gas  producers  (including  YPF)  signed  an  agreement  which  set  forth  the  percentage  of  regasified  LNG 
assigned to each natural gas producer for 2011. Amounts produced under this agreement were counted towards such producers’ commitments to supply 
natural gas to distributors under Resolution No. 599/07. As of the date of this annual report, similar agreements have not been entered into for years 
subsequent to 2011. 

ENARGAS  Resolution  No. 1410/10  was  amended  by  MINEM  Resolution  No. 89/2016,  dated  June 1,  2016,  which  required  ENARGAS  to 
develop  a  procedure  to  amend  and  supplement  ENARGAS  Resolutions  No. 716/1998  and  1410/2010  and  establish  daily  operating  conditions  of  the 
Transportation and Distribution Systems, established the volumes that distributors may request in order to satisfy priority demand and, if there has been 
a contract with a producer to fulfill such request, reduced the contracted volume requirement in accordance with the framework provided by Resolution 
No. 1,410/2010. Pursuant to this resolution, ENARGAS Resolution I/3833 was issued on June 5, 2016, which established the “Supplementary Procedure 
for Gas Requests, Confirmations and Control”. 

Pursuant to this resolution, on June 5, 2016 ENARGAS Resolution No. I/3833 was issued, which establishes the “Supplementary Procedure for 
Gas  Requests,  Confirmations  and  Control.”  The  purpose  of  the  Procedure  is  to  establish  the  transition  mechanism  and  application  criteria  for  the 
administration of the natural gas dispatch to preserve the operation of the transportation and distribution systems giving priority to the consumption of 
the Priority Demand in cases of supply crisis and / or emergencies which may put at risk the normal provision of the natural gas public service or which 
may affect the provision of another public service. 

The  new  Procedure  establishes  that  each  day  the  Distribution  Service  Providers  will  request  in  the  programming  computer  systems  of  the  Transport 
Companies  for  the  operational  day  n  +  1,  with  first  priority,  the  natural  gas  necessary  to  supply  the  Priority  Demand,  based  on  their  consumption 
estimate and in accordance with the contracted transport capacity and its supply agreements. 

The  confirmation  of  natural  gas  in  the  TSEP  (“Transport  System  Entering  Point”)  for  Priority  Demand  will  have  priority  over  other  segments.  The 
confirmation of gas for segments other than the Priority Demand will maintain the confirmation priority established by the Producer in the respective 
contracts with direct consumers (or Marketers), which will be informed to Transportation and Distribution Service Providers. 

The transportation nomination of each Distribution Service Provider will give priority to the supply of their Priority Demand over any other user of that 
Provider. 

The Providers of the Transportation and Distribution Service that verify that the transportation capacity is not sufficient to supply the Priority Demand 
must summon the Emergency Committee, chaired by the president of ENARGAS, who will procure the means to allocate the volumes in the emergency 
situation. 

125 

On June 6, 2017 ENARGAS Resolution No 4.502/17 was issued which approved the Procedure for the administration of the office in the Emergency 
Executive Committee (“EEC”), modifying the procedure for the delivery request and gas confirmations which were approved by ENARGAS Resolution 
No. 3,833/16  and  provided  for  measures  and  criteria  to  be  adopted  in  a  supply  crisis  of  the  Priority  Demand  for  Natural  Gas  declared  by  the 
Transportation Companies, Distribution Companies or the ENARGAS. 

Among such measures, it was provided that the EEC or (if the EEC disagrees to it) the ENARGAS, will define the way in which the Priority Demand 
will be supplied considering the quantities of natural gas available in each basin for each producer and discounting the amounts contracted to supply the 
Priority Demand. 

On  June 29,  2018,  ENARGAS  Resolution  No. 124/2018  was  published  in  the  Official  Gazette  which  (i) approves  the  restated  text  of  the  internal 
regulation  of  dispatch  centers  applicable  as  of  June 30,  2018;  (ii)  derogates  ENARGAS  Resolutions  No.  I-1410/10,  I-3833/16  and  I-4502/17;  (iii) 
acknowledges that ENARGAS has no observations to the reprogramming proposal made by the Transporter if there are no statements to the contrary 
within  one  hour  of  the  request;  and  (iv) establishes  that  during  this  winter  the  Transitory  Procedure  for  Dispatch  Management  in  the  Emergency 
Executive Committee shall be applicable. 

Under  the  energy  sector  normalization  process,  the  MINEM  called  on  natural  gas  producers  (including  YPF)  and  ENARSA  to  establish  the  basic 
conditions of those supply agreements to be executed to the distribution of Natural Gas through Networks as of January 1, 2018. The MINEM stated 
that before the end of the extension period established in Law No. 27,200 regarding the public emergency that began in 2002, Law No. 24,076 regained 
effectiveness as it sets forth that the price of natural gas supply agreements will be that determined by the supply and demand free interaction. 

In this sense, on November 29, 2017, natural gas producers (among them, YPF) and ENARSA, at the request of the MINEM, subscribed the “Terms and 
Conditions for the Provision of Natural Gas to Gas Distributors through Networks “(the” Terms and Conditions”). 

The Terms and Conditions establish the basic guidelines to assure the adequate supply of natural gas to the Distributors, and consequently to residential 
and commercial final consumers. Moreover, they establish the continuity of the gradual and progressive path of reduction of subsidies, all within the 
framework of the  process of normalization  of the  natural gas  market, which occurs  within the  period of validity of such Terms and Conditions until 
December 31, 2019 considered as the “transition period” until the normalization indicated above. 

The guidelines established in the Terms and Conditions include, among others, the recognition of the right to transfer to the gas tariff the cost of gas 
acquisition  paid  by  users  and  consumers;  establishes  the  available  volumes  that  each  producer  and  each  basin  must  make  available  daily  to  the 
distributors for each month, who may express their lack of interest before a certain date set forth in the Terms and Conditions; establishes penalties for 
non-compliance for any of the parties regarding their obligation to deliver or take gas; establishes gas prices for each basin for the next two years, in 
U.S. dollars, the parties being able to set prices lower than those established under the applicable free negotiations; establishes payment guidelines for 
the  purchases  made  by  the  Distributors  to  producers;  ENARSA  assumes  the  obligation  to  supply  the  demand  corresponding  to  areas reached  by  the 
subsidies  of  residential  gas  consumption  contemplated  in  article  75  of  Law  No. 25,565  (corresponding  to  the  areas  of  lower  price  of  residential  gas 
charged to users and consumers), during the period of Transition. 

The  Terms  and  Conditions  constitute  the  terms  and  conditions  to  consider  in  the  negotiations  of  their  respective  individual  agreements,  without  this 
being construed as an obligation. Additionally, the Terms and Conditions establish guidelines for early termination in the event of non-compliance by 
the parties. YPF fulfilled its commitment to sign supply agreements, according to the Terms and Conditions. 

As a consequence of certain macroeconomic variables, natural gas producers (including YPF) and distributors entered into a renegotiation process 
of the individual supply agreements entered into pursuant to the Terms and Conditions to address two main issues: (i) payment by distributors of debts 
arising from exchange rate differences (which resulted from the U.S. Dollars-Argentine Peso exchange rate used by distributors for natural gas volume 
prices payment (the exchange rate considered in natural gas tariffs) vs. the exchange rate that should have been considered as per the supply agreements, 
for April through September 2018 period) (“ER Debt”) and (ii) natural gas prices for the October-December 2018 period. 

Regarding debts arising from exchange rate differences, the recovery mechanism has not yet been defined or implemented, since SGE Resolution 
No. 20/2018 published on October 5, 2018 established that in relation to differences between the price of gas provided in the contracts and the price of 
gas recognized in the final tariffs of distribution companies, valued for the quantity of gas purchased from April 1 to September 30, 2018, ENARGAS 
would  instruct  distribution  companies  to  recover  the  credit  in  favor  of  producers  on  a  separate  line  in  the  invoice  to  be  issued  to  its  users,  in  24 
installments starting on January 1, 2019. 

126 

On  October 16,  2018  the  SGE  issued  Resolution  No. 41/2018  which  abrogated  Resolution  No. 20/2018  which  attempted  to  establish  an 
extraordinary and transitory mechanism to resolve the ER Debt by passing through such exchange rate difference into natural gas tariffs to be paid by 
final consumers. 

On November 16, 2018, the Argentine Government published Decree No. 1,053/18 in the Official Gazette, through which it assumed the payment 
of the daily differences accumulated on a monthly basis between the price of gas purchased by distributors and the price of natural gas included in tariff 
schemes effective  from  April 1, 2018 to March 31,  2019, exclusively generated due to exchange  rate  variations and corresponding  to the natural  gas 
volumes delivered in that same period. The conditions are as follows: 

• Payment shall be made in 30 consecutive monthly installments beginning on October 1, 2019, at an interest rate determined using the Banco de la 

Nación Argentina effective interest rate for 30 day deposits in Argentine Pesos.

•

Installments will be paid to distributors, and distributors will immediately pay natural gas producers. 

• Distributors and natural gas producers should adhere to this regime and waive any claims relating to this matter. 

In  addition,  Decree  No. 1,053/18  established  that  from  April  2019  onwards  future  gas  supply  agreements  between  distributors  and  natural  gas 
producers  shall  determine  that  in  no  event  will  additional  costs  generated  as  exchange  rate  differences  for  each  season  be  passed  through  to  final 
consumers. It also empowered ENARGAS to further regulate the abovementioned conditions. As of the date of this annual report, ENARGAS has not 
implemented this regime. 

On  February 12,  2019,  Resolution  ENARGAS  N°  72/2019  was  published  in  the  Official  Gazette,  which  approved  the  methodology  for  gas 
transfer pricing and the general procedures for the calculation of the accumulated daily differences, which will be in effect as of April 1, 2019. Such 
resolution sets forth, among other things, with regards to transfer pricing for gas agreed in dollars, that ENARGAS will determine the type of exchange 
rate to the be used in the conversion to Argentine pesos based on the BNA (Divisas) average seller exchange rate observed between the first and the 
fifteenth day of the month immediately preceding each seasonal period, or the exchange rates contained in the contracts when they contemplate lower 
rates.  Regarding  volumes  of  gas  subject  to  export  which  are  not  covered  by  specific  agreements,  the  provisions  of  Section 9.4.2.6  of  the  Basic 
Regulations  of  the  Distribution  License  and  Decree  No. 1020/95  will  apply,  as  long  as  the  necessary  information  for  purposes  of  the  applicable 
calculations is available. 

On August 27, 2012, Resolution No. 1,445/2012 of the Secretariat of Energy was published in the Official Gazette, according to considerations set by 
Decree No. 1,277/2012, which modified gas prices at the wellhead for compressed natural gas (CNG) which represents an increase of approximately 
369% of the prices realized by the Company for such segment product. 

On February 14, 2013, Resolution No. 1/2013 of the Commission was published in the Official Gazette. This resolution creates the “Natural Gas 
Additional Injection Stimulus Program.” Under this regulation, gas producing companies were invited to file with the Commission before June 30, 2013 
projects to increase natural gas injection, in order to receive a compensation up to U.S.$7.50 per mmBtu for all additional natural gas injected. These 
projects  shall  comply  with  minimum  requirements  established  in  Resolution  No. 1/2013  and  will  be  subject  to  consideration  approval  by  the 
Commission, including a maximum term of five years, renewable at the request of the beneficiary, upon decision of the Commission. If the beneficiary 
company in a given month does not reach the committed production increase it will have to make up for such volumes not produced. In addition, the 
Commission may withdraw a previously approved proposal to increase the total injection of natural gas if some of the following events occur: (i) any 
omission, inaccuracy or distortion of information provided by a company participating in a project or during its execution; (ii) breach of the obligations 
set forth in Decree No. 1,277/2012 and its regulations or supplementary acts; (iii) breach by a company of its obligations under the program after notice 
of not less than 15 business days; (iv) if the import price is equal to or lower than the price of the additional natural gas injected for at least 180 days or 
(v) if the value of a company’s supply contracts or invoices used in the monthly calculation corresponding to each month covered by the program had 
weighted average price decreases or unjustified amounts. On May 23, 2013, the Commission approved the project submitted by YPF. A similar program 
was created under Resolution No. 60/2013 of the Commission, as amended by Resolution No. 83/2013 of the Commission for gas producers that failed 
to  file their  natural  gas  additional  injection  program  filings  before the expiration  date established by Resolution  No. 1/2013 of  the  Commission. The 
compensation to be received under this new program varies from U.S.$ 4.00 per mmBtu to U.S.$ 7.50 per mmBtu, depending on the production curve 
reached  by  the  applicable  company.  Additionally,  a  third  stimulus  program  entered  into  effect  under  Commission  Resolution  No. 185/2015  for 
companies without any prior gas production in Argentina at the time of issuance of the resolution. Similar to the Gas Plan, companies with an approved 
program under this new resolution will receive compensation for the difference between the price obtained in the market for the sale of all their gas 

127 

production  and  U.S.$  7.50  per  mmBtu.  The  gas  production  subject  to  such  compensation  only  applies  to  the  production  from  areas  acquired  by 
companies  with  approved  programs  under  either  Resolution  No. 1/2013  or  Resolution  No. 60/2013,  as  long  as  such  production  was  computed  under 
these programs as “increased injection” as opposed to “base injection”. 

On May 18, 2016, MINEM Resolution No. 74/2016 created the “Natural Gas New Projects Stimulus Program” in order to incentivize natural gas 
production for companies submitting new natural gas projects that are not beneficiaries of the “Natural Gas Additional Injection Stimulus Program” or 
the “Natural Gas Injection Stimulus for Companies with Reduced Injection” created by Resolutions No. 1/2013 and 60/2013, respectively, of the former 
Commission. The submission of new projects, which must be approved by the Secretariat of Hydrocarbon Resources, may obtain a stimulus price of 
U.S.$ 7.50/mmBtu. 

Moreover,  the  “Natural  Gas  Injection  Stimulus  for  Companies  without  Injection”,  created  by  Resolution  No. 185/2015  of  the  former  Strategic 
Planning  and  Coordination  Commission  of  the  Hydrocarbon  Investments  National  Plan  has  been  abolished,  but  any  projects  submitted  under  such 
program which are pending approval must be evaluated under the “Natural Gas New Projects Program”. 

The “Natural Gas New Projects Program” will be effective from the date of the publication of the resolution in the Argentine Official Gazette 
(May  18,  2016)  until  December 31,  2018.  The  requirements  to  be  considered  a  new  natural  gas  project  are  as  follows:  it  must  (i) come  from  an 
exploitation concession granted as a result of a discovery reported after the effective date of Resolution No. 1/2013 of the former Commission; (ii) come 
from an exploitation concession of areas classified as “Tight Gas” or “Shale Gas”; or (iii) belong to companies without natural gas injection registers 
which acquire an interest in areas belonging to companies registered in the “Natural Gas Additional Injection Stimulus Program” or the “Natural Gas 
Injection Stimulus for Companies with Reduced Injection” created by Resolutions No. 1/2013 and 60/2013, respectively, of the former Commission, but 
for which total injection coming from the areas in question, including the acquired areas, would have been zero during the period in which the selling 
company would have calculated its base injection. 

Following this Resolution, no new projects may be submitted under the natural gas production incentive Program known as “Gas Plus”, created by 
Resolution  No. 24/2008  of  the  former  Energy  Secretariat  of  the  former  Ministry  of  Federal  Planning,  Public  Investment  and  Services,  as  amended. 
Notwithstanding  the  foregoing,  any  projects  approved  under  said  Program  would  remain  in  full  force  according  to  the  terms  of  their  respective 
approvals. 

On May 20, 2016, Decree No. 704/2016 was published, whereby the pending debt which were in Peso terms for the natural gas stimulus programs 
debt was cancelled in Argentine National Bonds nominated in U.S. dollars and at an interest rate of 8% per annum maturing in 2020 (“BONAR 2020 
USD”). 

Accordingly, on July 13, 2016, the Group received, under the Natural Gas Additional Injection Stimulus Program, BONAR 2020 USD, with a 

face value of U.S.$ 630 million. 

In addition, on September 21, 2016, under the Supply of Propane Gas for Undiluted Propane Gas Distribution Networks Agreement, the Group 

received BONAR 2020 USD, with a face value of U.S.$ 12 million. 

MINEM Resolution No. 97/2018 

On April 3, 2018, the MINEM Resolution No. 97/2018 was published in the Official Gazette that approves the procedure for cancelation of the pending 
compensations  for  settlement  and/or  payment  in  the  context  of  the  “Natural  Gas  Surplus  Additional  Injection  Stimulus  Program”, the  “Natural  Gas 
Surplus  Injection  Stimulus  Program  for  Companies  with  Reduced  Injection”  and  the  “Natural  Gas  New  Projects  Program”  to  which  beneficiary 
companies may adhere (the “Procedure”). 

Gas producing companies are invited to join the Procedure by filing a form during 20 business days following the publication in the Official Gazette of 
the Resolution. 

Each company may opt to receive compensations under the approved Procedure by demonstrating its accession within 20 business days of publication 
of  the  Resolution.  It  is  required  to  waive  all  rights,  actions,  appeals  and  claims,  administrative  and/or  judicial,  based  on  the  Procedure,  except  for: 
(i) challenge of the administrative acts that determine compensations that correspond according to the Procedure; and (ii) failure to make the payments 
provided under the Procedure for a minimum amount of three installments, at the discretion of each beneficiary company. 

128 

The amount of the compensation is determined in the following way: 85% of the amount in dollars calculated according to the exchange rate at 
the moment of the injection (“Program Exchange Rate”) and 15% of the amount in dollars multiplied by the quotient of the Program Exchange Rate and 
the  exchange  rate  corresponding  to  the  payment  dates  of  the  compensation  resolutions  that  have  already  been  issued  or  the  date  of  publication  of 
Resolution No. 97/2018, as the case may be. The debt will begin to be repaid on January 2019 in 30 monthly and consecutive installments, in pesos at 
the exchange rate of Communication “A” 3,500 Wholesale of the BCRA monthly average of the month preceeding each installment. 

On May 5, 2018, YPF adhered to the repayment Procedure. 

On December 4, 2018, Law No. 27,467 which approved the 2019 Budget of the National Administration was published in the Official Gazette, 
which includes in its Article 55 the authorization for the issuance of public debt instruments for up to U.S.$ 1.6 billion for the cancellation of the 2017 
compensations of Plan Gas I (according to Resolution No. 97 of March 28, 2018 of the Ministry of Energy). 

On February 21, 2019, Resolution SGE 54/2019, which partially modified Resolution 97/2018, was published in the Official Gazette, in order to 
conform  Resolution  97/2018  to  the  payment  mechanism  set  forth  in  article  55  of  Law  No. 27,467.  It  provides,  among  other  things,  that  in  order  to 
request  payment  in  accordance  with  such  mechanism,  the  beneficiary  must  provide  its  consent  (within  ten  of  receiving  notice)  to  waive  all  rights, 
actions or claims in relation to such programs, the administrative compensation acts and payment orders which they may have issued prior to such date. 

On February 28, 2019, Resolution No 21/19 from the Ministry of Finance was published in the Official Gazette which established the issuance on 
February 27,  2019,  of  the  Natural  Gas  Program  Bonds,  with  an  aggregate  nominal  value  of  up  to  U.S.$  1.6 billion,  maturity  on  June 28,  2021,  and 
amortization in 29 consecutive monthly installments. The Natural Gas Program Bonds do not accrue interest. 

Also on February 28, 2019, YPF received notice from the SGE informing it that, in accordance with the framework of Resolution No. 97/2018, 

YPF was entitled to an aggregate compensation of U.S.$758 million. 

On March 1, 2019, the Company presented its consent letter to the SGE in the terms provided under the SGE Resolution No. 54/19. 

As of the date of this annual report we have not received any payment compensation. 

MINEM Resolution No. 46/2017 

On March 6, 2017, the MINEM Resolution No. 46-E/2017 was published in the Official Gazette, which approved the “Investment in Natural Gas 
Production from Non-Conventional Reservoirs Stimulus Program.” The program  was established in order to  stimulate  the  investments  in  natural  gas 
from non-conventional reservoirs in the Neuquina basin and will be in effect until December 31, 2021. 

Resolution No. 46/2017 establishes compensation for the volume of non-conventional gas production from concessions located in the Neuquina 
basin  included  in  the  program.  To  be  included  in  the  program,  the  concessions  must  have  a  specific  investment  plan  approved  by  the  province’s 
application authority and the Secretariat of Hydrocarbon Resources. 

The  compensation  will  be  determined  by  deducting  from  the  effective  sales  price  obtained  from  sales  to  the  internal  market,  including 
conventional and non-conventional natural gas, the minimum sales prices established by Resolution No. 46/2017 each year, multiplied by the volumes 
of production of non-conventional gas. The minimum prices established by Resolution No. 46/2017 are U.S.$ 7.50 per mmBtu for 2018, U.S.$ 7.00 per 
mmBtu for 2019, U.S.$ 6.50 per mmBtu for 2020 and U.S.$ 6.00 per mmBtu for 2021. 

Compensation  from  the  program  shall  be  paid,  for  each  concession  included  in  the  program,  88%  to  the  companies  and  12%  to  the  province 
corresponding to each concession included in the program. 

On November 2, 2017, Resolution MINEM 419-E/2017 was published and its Annex replaces the similar Annex of Resolution 46-E/2017. The 

new resolution modifies the previous one in the following aspects: 

a)  It  defines  that  the  Initial  Production  to  be  computed  will  be  the  “monthly  mean  Non-Conventional  Gas  production  assessed  for  the  period 
between July 2016 and June 2017”. Also, it states that the Production Included, to the effect of the compensation, shall be i) for the concessions with 
Initial Production lower than 500,000 cm/d, the total monthly production of Non-Conventional Gas coming from such Included Concession, to which 
the  requesting  company  is  entitled,  and  ii)  for  the  concessions  with  Initial  Production  higher  than  500,000  cm/d,  the  total  monthly  production  of 
Non-Conventional Gas coming from such Included Concession, to which the requesting party is entitled, discounting the Initial Production. 

129 

b) It  modifies the definition of  Effective Price,  previously defined  as  “the  average  price weighted  by  volume of  total natural gas  sales  of  each 
company in the domestic market”, to “the average price weighted by volume of total natural gas sales in the Argentine Republic that will be published 
by the Secretariat of Hydrocarbon Resources”, regulating the guidelines to be followed for such calculation. 

c) A requirement to qualify for the Program is included, that is, that the investment plan submitted for each concession reaches a yearly mean 
production,  in  any  consecutive  period  of  twelve  months  before  December 31,  2019,  equal  to  or  higher  than  500,000  cm/d,  and  the  obligation  to 
reimburse  the  amounts  of  the  compensation  received  (updated  to  reflect  interest)  corresponding  to  the  concessions  that  do  not  reach  the  above 
mentioned  production  level,  with  the  possibility  that  the  Secretariat  of  Hydrocarbon  Resources  may  require  filing  a  surety  bond  to  guarantee  the 
eventual reimbursement of the compensations received by the participating companies, and retaining the power to suspend payments if such bond is not 
submitted. 

On November 17, 2017, Resolution MINEM No. 447-E/2017 which extends the Stimulus Program to the non-conventional gas production from 
the Austral Basin was published. The only difference with respect to the Program applicable to the Neuquina Basin is that this resolution allows the 
Hydrocarbon  Secretary  to  determine  special  technical  conditions  (such  as  initial  production  flow)  that  the  production  must  meet  in  order  to  be 
considered “non-conventional gas” and thus be suitable for the program. 

During 2018, YPF has filled requests to be included in the program for non-conventional gas production from several concessions located in the 

Neuquina basin. 

On January 23, 2018, MINEM Resolution No. 12-E/2018, which modified Resolution No. 46-E/2017, was published in the Official Gazette. Said 

Resolution entails the following: 

(i) Makes the incentives applicable to the adjacent concessions that are operated in a unified manner and comply with the following requirements: 
have a common investment plan; be operated in joint manner using, substantially, the same surface installations; in case of co-ownership, there shall be 
the  same  participation  percentages  in  all  concessions  and  every  transfer  of  participation  is  performed  in  a  joint  and  simultaneous  manner  by  all 
participants. 

(ii) Adjusts the payment date of the first compensation under the Program and, correspondingly, performs the following revisions related to initial 
provisional  payment,  establishing  that  for  requests  presented  until  January 31,  2018,  such  date  shall  be  the  respective  date  in  January  2018,  and  for 
requests  presented  after January 31, 2018,  such date  shall be  the respective  date in  the month in  which  the request for  inclusion in the Program was 
presented. 

On December 4, 2018, Law No. 27,467 corresponding to the Budget of the National Administration for the year 2019, established in its section 58 
the  creation  of  a  guarantee  trust  for  contingent  liabilities  of  the  Gas  Plan  IV  (“Stimulus  Program  for  Investments  in  Natural  Gas  Production 
Developments  from  Non-Conventional  Reservoirs”  created  by  Resolution  No. 46  dated  March 2,  2017  issued  by  the  former  MINEM)  in  order  to 
guarantee up to 30% of the obligations that may arise under such program after January 1, 2019. 

In  connection  with  Fernández  Oro  Concession,  the  Secretariat  of  Energy  issued  resolutions  authorizing  the  payment  to  YPF  of  Definitive 
Compensations for the first quarter of 2018 and Provisional Compensations for the third quarter of 2018, whose amounts were determined considering 
as  a  limit  the  estimation  of  the  Included  Production  YPF  initially  reported.  Recently,  YPF  has  administratively  challenged  these  resolutions, 
understanding  that  the  amount  of  the  Compensations  must  be  determined  on  the  basis  of  the  production  actually  produced  each  month  in  the 
Concession, without applying any limit. 

As  of  the  date  of  this  annual  report,  YPF  subscribed  to  the  Program  for  its  participation  in  the  concessions  known  as  Aguada  Pichana  Este, 

Aguada Pichana Oeste-Aguada de Castro, Estación Fernández Oro and La Ribera I and II. 

Tariffs 

On April 4, 2014, Resolution S.E. No. 226/2014 of the former Argentine Secretariat of Energy was published in the Official Gazette. Under 
this resolution, the Secretariat of Energy set new prices for residential, commercial consumers and compressed natural gas consumers. Residential and 
commercial consumers that achieve certain consumption savings compared to prior years will be: (i) excluded from the price increase or (ii) subject to a 
lower price increase. Industrial users and power generation plants are excluded from the price increase. Consumers served by distributor Camuzzi Gas 
del Sur S.A., which is not an affiliate of YPF, or its sub-distributors, are excluded. 

On November 17, 2014, Resolution No. 231/2014 of the Commission was published in the Official Gazette. Under this resolution, the price 
of compressed natural gas in service stations will be raised by the same percentage as the weighted average price within Argentina, excluding taxes, of 
“super” quality gasoline over 93 octane or of any product that replaces it in the future as provided for under the resolution. 

130 

After  public  hearings  with  respect  to  the  tariff  review  were  held  on  September 16,  17  and  18,  2016,  MINEM  issued  Resolution 
No. 212/2016 on October 7, 2016 that set forth new TSEP prices for natural gas and new natural gas tariff schedules for users who purchase gas from 
distributors. 

Resolution No. 212/2016 instructs the Secretariat of Hydrocarbons to, until TSEP gas prices are established by the free interaction of supply 
and demand, submit to the MINEM for its approval a proposal of natural gas TSEP prices corresponding to each half-year period, starting April 1 and 
October 1 of each year, based on the values contemplated in the subsidy reduction scheme, adjusting the target price for each half-year period, as per the 
market conditions at the time of elaboration of the proposed prices. Such a proposal shall be submitted 30 days in advance at the beginning of each half-
year period and shall be submitted with a report containing the basis of the adjustments or modifications proposed. 

Resolution No. 212/2016 also instructs ENARGAS to provide for any such measures as required so that the final amount, including taxes of 
bills issued by distributors of utility gas through networks across the country, that users are required to pay based on consumptions after the effective 
date  of  the  TSEP  gas  prices  established  in  this  resolution,  does  not  exceed  maximum  amounts  equivalent  to  the  percentages  below,  considered  as 
incremental percentages over the total amount, including taxes, of the bill issued to the same user for the same billing period in the previous year: 

• Users R1-R23: 300%; 

• Users R31-R33: 350%; 

• Users R34: 400%; and 

• Users SGP: 500%. 

It further sets forth that the increase limits established above on the final invoice amounts shall apply, provided that the total amount of the bill 

exceeds the amount of Ps. 250. 

On  such  same  date,  ENARGAS  published  Resolutions  No. 4,044/2016,  4,045/2016,  4,046/2016,  4,047/2016,  4,048/2016,  4,049/2016, 
4,050/2016, 4,,051/2016, 4,052/2016, 4,053/2016 and 4054/2016, whereby it approved the tariff schedules for the users in the following license areas: 
Metrogas  S.A.,  Gasnea  S.A.,  Gas  Natural  Ban  S.A.,  Camuzzi  Gas  Del  Sur  S.A.,  Camuzzi  Gas  Pampeana  S.A.,  Distribuidora  de  Gas  Cuyana  S.A., 
Distribuidora de Gas del Centro S.A., Gasnor S.A., Litoral Gas S.A., Transportadora de Gas del Norte S.A. and Transportadora de Gas del Sur S.A. 

On February 16, 2017, MINEM published Resolution No. 29-E/2017, through which it called a public hearing to be held on March 10, 2017 to 
consider new natural gas prices at TSEP that would be determined to apply to the half-year period commencing in April 2017. The hearing took place, 
and the final report by the Secretariat of Hydrocarbon Resources was issued to the MINEM; See – “New gas prices at the TSEP and Metrogas transition 
tariff schemes.” 

Tariff renegotiation 

Transitional Agreement 2017 

On March 30, 2017, Metrogas executed a Transitional Agreement with the MINEM and the Ministry of Finance providing for the temporary adjustment 
of prices and tariffs for the Natural Gas Distribution Public Service, the specific impact of the amounts provided therein until the subscription of the 
Memorandum of Agreement for Comprehensive Contractual Renegotiation and the entry into force of the definitive tariff schemes resulting from the 
Comprehensive Tariff Review (the “CRT”). The 2017 Transitional Agreement is supplementary to the 2008 Transitional Agreement and amends the 
2017 Transitional Agreement and the 2016 Transitional Agreement previously executed. 

The 2017 Transitional Agreement, which is not subject to ratification by the PEN establishes a transitional tariff regime as of April 1, 2017, consisting 
of the readjustment of tariffs based on the guidelines necessary to maintain the continuity of the service for the purpose of allowing Metrogas to meet its 
operating and maintenance, administration and marketing expenses, those expenses corresponding to the execution of the mandatory investment plan 
determined by the ENARGAS and to comply with the respective payment obligations, maintaining its chain of payments for the purpose of ensuring the 
continuity of the regular provision of the public service under their charge until the entry into force of the tariff regime resulting from the Memorandum 
of Agreement for a Contractual Renegotiation. 

Likewise, the 2017 Transitional Agreement provides for the transfer of the impact of changes in tax regulations pending resolution, except for the, and 
incorporates a Mandatory Investment Plan to which Metrogas is committed. 

131 

Lastly,  Metrogas  will  not  be  authorized  to  distribute  dividends  without  previously  proving  to  ENARGAS  the  full  compliance  with  the  Mandatory 
Investment Plan. 

On March 30, 2017, the MINEM instructed the ENARGAS, through Resolution No. 74 - E/2017, to put into effect the tariff schemes resulting from the 
CRT process. 

In this regard, it set forth that for the gradual and progressive implementation of this measure, the ENARGAS should apply on a progressive basis, the 
rate  increases  resulting  from  the  CRT  as  follows:  30%  of  the  increase,  from  April 1,  2017,  40%  of  the  increase,  as  of  December 1,  2017,  and  the 
remaining 30%, as of April 1, 2018. 

Moreover, and for cases in which the corresponding Memorandum of Agreement for a Contractual Renegotiation had not entered into force, it instructed 
the ENARGAS to apply to the Licensees (including Metrogas) a transitory tariff adjustment because of the CRT. 

On March 31, 2017, ENARGAS Resolution No. 4,356/2017 was published in the Official Gazette through which the tariff schemes resulting from the 
Metrogas  CRT,  effective  as  of  April 1,  2017  and  the  temporary  tariff  schemes  applicable  to  Metrogas  users  were  approved.  Through  differentiated 
tariffs, ENARGAS Resolution No. 4,356/2017 determined tariff schemes for residential users who recorded savings in their consumption equal to or 
greater  than  15%  with  respect  to  the  same  period  of  2015,  as  well  as  those  that  would  apply  to  the  beneficiaries  of  the  “Social  Tariff”  (Resolutions 
No. 28/2016 of the MINEM and ENARGAS No. I-2,905/2014 and No. 3,784/2016) and the Entidades de Bien Público (Public Welfare Entities) (Law 
No. 27,218). 

The tariff schemes corresponding to beneficiaries of the “Social Tariff” were rectified by ENARGAS Resolution No. 4,369 2017. The billing resulting 
from  the  application  of  the  new  transitory  tariff  shames  must  respect  the  limits  established  in  Article  10  of  MINEM  Resolution  No. 212/2016,  and 
therefore the criteria of ENARGAS Resolution No. I-4,044/2016 are maintained. 

Likewise, ENARGAS Resolution No. 4,356/2017 overruled ENARGAS Resolutions No. I-2,407/12 and No. I-3,249/15 that enabled the collection of a 
fixed amount per invoice under the operation of the Fund for Gas Distribution Consolidation and Expansion Works (“FOCEGAS “). 

In addition, ENARGAS Resolution No. 4,356/2017 approved: (i) the technical economic studies of the Company’s CTR, (ii) the non-automatic Semi-
Annual  Adjustment  Methodology  to  become  effective  jointly  with  the  License  Readjustment  Memorandum  of  Agreement  and  (iii) the  Metrogas 
Investment Plan for the next five-year term. 

On  October 24,  2017,  and  through  ENARGAS  Resolution  No. 74/2017,  a  public  hearing  was  called  for  November 15,  2017  in  order  to  consider  the 
transitory tariff adjustment effective as of December 1, 2017, corresponding to Metrogas. 

On  December 1,  2017,  the  following  were  published  in  the  Official  Gazette:  (i) ENARGAS  Resolution  No. 131/2017  that  ordered  (a) to  declare  the 
validity  of  the  Public  Hearing  called  by  ENARGAS  Resolution  No. 74/2017,  (b)  approve  Metrogas  temporary  tariff  scheme  applicable  as  of 
December 1, 2017; and (c) approve new values for the Rates and Charges received by Metrogas for Additional Services; and (ii) ENARGAS Resolution 
N° 132/2017 that provides for a bonus to be implemented by Metrogas in favor of certain users who (a) record savings in their consumption; or (b) are 
beneficiaries of the Social Tariff. 

On  January 31,  2018,  ENARGAS  Resolution  No. 249/2018  was  published  in  the  Official  Gazette,  which  called  for  a  public  hearing  to  be  held  on 
February 22,  2018  to  consider  (i) the  application  of  the  Semi-Annual  Tariff  Adjustment  Methodology,  if  applicable,  for  the  adjustment  of  Metrogas 
tariffs; (ii) the application of the transfer to tariffs of the price of the purchased gas; and (iii) methodological alternatives for a more predictable billing of 
residential users’ consumption. 

On  March 27,  2018,  a  letter  of  intent  was  entered  into  with  ENARGAS,  producers,  distributors  and  transporters  of  natural  gas  with  the  objective  of 
committing efforts towards the development of a financing program of wintertime consumptions of natural gas between the signing parties. 

On  May 23,  2018,  MINEM  Resolution  No. 218/2018  (previously  regulated  by  ENARGAS  by  means  of  Resolution  No. 86/2018)  establishes  the 
suspension of the application of the discount criteria for social tariff users according to Resolution No. 474/2017 for consumptions made during May 
and June 2018, while the social tariff regime pursuant to MINEM Resolution No. 28/2016 must apply for the invoicing of said consumptions, which 
establishes a discount of 100% of the consumed natural gas. 

132 

On  June 12,  2018,  ENARGAS  Resolution  No. 97/2018  that  establishes  the  Financing  Program  of  Wintertime  Consumptions  of  Natural  Gas  (the 
“Program”)  was  published  in  the  Official  Gazette.  Adherence  to  the  program  by  beneficiary  users  is  optional  and  voluntary.  In  accordance  with  the 
terms and conditions of the Program, residential and commercial consumers may finance the payment of 25% of the invoices issued between July 1 and 
October 31, 2018. The applicable interest rate shall be the private non-finance sector electronic channel rate of the BNA for placement at 30 days of the 
month prior to the month in which the invoice is issued. The accumulated financing and its interests are recovered as of the issuance of regular invoices 
from November 1, 2018, and for three consecutive periods for bimonthly clients and six consecutive periods for monthly clients. The financing involves 
each activity segment (gas, transport and distribution) and was exceptional for the winter of 2018. 

As a consequence of the exchange rate variation, producers and distributors of natural gas initiated a renegotiation process with regard to the particular 
agreements  signed  under  the  Terms  and  Conditions,  with  prices  denominated  in  U.S.  dollars.  This  process  has  not  yet  terminated  and  includes  two 
principal topics: (i) payment of debts generated due to the difference between the exchange rate at which the distributors made their payments and the 
exchange rate set forth contractually (period April – September 2018); and (ii) gas price to be applied for the period October – December 2018. 

In terms of debts generated by the exchange rate differences, on November 18, 2018, by means of Decree No. 1,053/18, the Argentine Government, as 
an  exception,  assumed  responsibility  for  the  payment  of  the  daily  differences  accumulated  monthly  between  the  value  of  gas  purchased  by  the 
distributors and the tariffs in force between April 1, 2018, and March 31, 2019. See “—Natural Gas.” 

On  August 13,  2018,  ENARGAS  Resolution  No. 184/2018  was  published  in  the  Official  Gazette,  which  called  for  a  public  hearing  to  be  held  on 
September 4, 2018 to consider (i) the application of the Semi-Annual Tariff Adjustment Methodology, for the adjustment of Metrogas Tariffs; (ii) the 
application of the transfer to tariffs of the price of the purchased gas and the consideration of the pass-through of the debt arising from cumulative daily 
differences; and (iii) the presentation of the Argentine Gas Subdistribution Institute. 

On October 8, 2018, ENARGAS Resolution No. 281/2018 was published in the Official Gazette that (a) declare the validity of the Public Hearing called 
by ENARGAS Resolution No. 184/2018; (b) approve Metrogas temporary tariff scheme applicable as of October 8, 2018; (c) approve new values for 
the Rates and Charges received by Metrogas for Additional Services; (d) order Metrogas to implement the corresponding bonus to beneficiaries of the 
Social Tariff equivalent to 100% of the gas price on a block of consumption established by Resolution MINEM No. 474/2017. Gas consumptions over 
such block have to be fully paid; (e) limit to 50% the gas price increase for SGP 1 and SGP 2 Social Tariff consumers for consumptions made as from 
October 1, 2018; (f) order SGP 1 and SGP 2 Social Tariff consumers (small industries and retail stores) to register in the Company Registry established 
by  Law  No. 24,467  or  being  beneficiaries  of  Law  No. 27,218  that  established  Public  Welfare  Entities  regime;  (g) SGP  1  and  SGP  2  bonus  shall  be 
detailed in the invoice in a separate line as “Bonus Resolution N° 14/18”; and (h) GNC consumers shall be entitled to request distribution services only 
in case distribution companies have guaranteed the purchase of natural gas for twelve months and as from April 1, 2019 and shall inform distribution 
companies their natural gas needs 60 days in advance as from April 1, 2019. 

On October 12, 2018, ENARGAS Resolution No. 292/2018 amended Metrogas tariff scheme and values for the Rates and Charges. 

Memorandum of Understanding for the Natural Gas Distribution License Contract (also known as “Memorandum of Understanding for the 

Comprehensive Contractual Renegotiation”) 

On  March 30,  2017,  and  within  the  framework  of  the  renegotiation  process  of  the  public  service  contracts  established  by  the  Emergency  Law,  its 
extensions  and  Decrees  No. 367/2016  and  N°  2/2017,  Metrogas  subscribed  with  the  MINEM  and  with  the  Ministry  of  Finance,  a  Memorandum  of 
Agreement for the Adaptation of the Natural Gas Distribution License Agreement (which contains the terms of the comprehensive renegotiation and 
conditions  for  the  adjustment  of  the  License  Agreement.  The  Memorandum  of  Agreement  is  based  on  the  2008  Transitional  Agreement,  the  2014 
Transitional Agreement, the 2016 Transitional Agreement and the 2017 Transitional Agreement. 

The  provisions  contained  in  the  Memorandum  of  Agreement,  once  it  has  entered  into  full  force  and  effect  after  being  ratified  by  the  PEN,  will  be 
applied during the contractual period ranging from January 6, 2002 and the termination of the License Agreement. 

A series of guidelines to be contemplated by the CRT process are established in the terms provided for therein. 

The Metrogas tariff scheme resulting from the Integral Tariff Review according to the indicated guidelines will be applicable once all the procedures 
provided  for  the  entry  into  force  of  the  Memorandum  of  Agreement  has  been  fulfilled.  The  CTR  will  become  in  full  force  and  effect  not  later  than 
December 31,  2017.  In  the  event  that  ENARGAS  provides  for  the  phased  and  progressive  application  of  the  tariff  increase  resulting  from  the 
Comprehensive Tariff Review, the application of the last step may not exceed April 1, 2018. 

133 

As a condition prior to ratification, the Memorandum of Agreement for the Comprehensive Contractual Renegotiation provides for the suspension and 
withdrawal of all claims, appeals and complaints filed, pending or in the process of being executed, whether administrative, arbitral or judicial, in the 
Argentine  Republic  or  abroad,  which  are  founded  or  linked  to  the  facts  or  provided  measures,  with  respect  to  the  License  Agreement,  as  of  the 
Emergency  Law  and/or  in  the  annulment  of  the  PPI  Index  (Producer  Price  Index  of  the  United  States  of  America).  Moreover,  the  Memorandum  of 
Agreement must be ratified by the Shareholders’ Meeting of Metrogas, so that the PEN issues the Decree ratifying the terms of the Memorandum of 
Agreement. On April 27, 2017, the Shareholders’ Meeting of Metrogas ratified the Memorandum of Agreement for the Adaptation of the Natural Gas 
Distribution License Agreement. 

Finally, the Memorandum of Agreement provides for the Company’s commitment to make, during the effective term of the License, plus its potential 
ten-year extension and within the area of its License, additional sustainable investments equivalent to the amount of the award rendered in the arbitration 
proceedings  in:  “BG  Group  Plc.  vs.  The  Argentine  Republic  (UNC  54  KGA)”  with  the  proportional  abatement  percentage  that  would  have  been 
established in the payment agreement and excluding the amounts corresponding to the default interest on the payment of the award. The amount and the 
plan for additional investments will be determined by ENARGAS at the proposal of the Company and they will not be included in the rate base. 

With  respect  to  those  Licensees  whose  Memorandum  of  Agreement  had  not  entered  into  effect,  the  ENARGAS  was  instructed  to  apply  to  them  a 
temporary adjustment of tariffs on account of the CTR, taking into consideration, to such effects, the studies carried out under such CTR in compliance 
with the provisions set forth in Article 1 of MINEM Resolution No. 31/2016. 

The Memorandum of Agreement is subject to the controls established by the Emergency Law in order for the PEN to issue the ratification Decree. On 
March 28,  2018  Decree  No. 252/2018  was  published  in  the  Official  Gazette  by  which  the  PEN  ratified  the  Memorandum  of  Agreement.  Also, 
Resolution ENARGAS No. 300/2018 was published on that day, with the new tariffs scheme applicable as from April 1, 2018. 

On September 27, 2018, SGE Resolution No. 14/2018, applicable to invoicing of distributors as of October 1, 2018, was published, which, inter alia, 
(i) revokes the ceilings and discounts that were established in due time in MINEM Resolutions No. 212/2016 and No. 474/2017 and sets forth a new 
discount of 100% for social tariff users for the consumption block set forth in Annex II of MINEM Resolution No. 474/2017 and consumptions that 
exceed  said  block  are  paid  at  100%;  and  (ii) established  that  the  Fiduciary  Fund  for  Residential  Gas  Consumption  Subsidies  (Section  75  of  Law 
No. 25,565) shall be 2.96% on the gas price in the TSEP by cubic meter and established that the invoicing shall be adjusted to the procedures established 
by ENARGAS. 

On October 8, 2018, Resolution ENARGAS No. 281/2018 was published in the Official Gazette, declaring valid Public Hearing No. 96 and approving 
the Metrogas Tariff Tables, in force as of the day of their publication for the summer period 2018-2019. Subsequently, on October 12, 2018, Resolution 
ENARGAS  No. 292/2018  was  published  in  the  Official  Gazette  rectifying  the  tariff  tables  of  mentioned  Resolution  ENARGAS  No. 281/2018,  with 
retroactive application as of October 8, 2018. ENARGAS Resolution No. 292/2018 published on October 12, 2018, modified the Tariff Schemes and the 
Schedule of Rates and Charges for the additional services provided by Metrogas. 

In addition, on the same date, MINEM Resolution No. 91/2018 was published in the Official Gazette, by means of which the periods for adjustment of 
the  purchased  gas  price  variations  or  the  seasonal  adjustment  and  the  semi-annual  adjustment  of  the  tariffs  are  unified,  establishing  that  once  the 
transition  period  has  passed,  the  adjustments  shall  be  seasonal,  covering  the  periods  of  April 1  to  September 30  of  each  year  and  of  October 1  to 
March 31 of the following year. 

Temporary economic assistance 

MINEM Resolution No. 312-E/2016 was published in the Official Gazette, on December 30, 2016, which ordered a new temporary economic assistance 
to  the  Licensees  of  the  Natural  Gas  Distribution  Service  through  Networks  for  the  period  April-September  2016,  for  the  purpose  of  funding  the 
mandatory investments established (with respect to Metrogas) in ENARGAS Resolutions No. 3,726/2016 and No. 4,044/2016, and the payment to gas 
producers; all of which is on account of the CTR. 

Under  the  terms  of  the  Resolution,  the  transfer  of  the  amounts  assigned  to  Metrogas  of  759  was  applicable  as  long  as,  at  the  discretion  of  the 
ENARGAS, the financial situation of Metrogas that gave rise to the assistance was maintained taking into account the availability of funds to meet its 
investment obligations and payments to gas producers. 

For the release of the funds corresponding to the temporary financial assistance, Metrogas had to file a sworn statement with the ENARGAS, in the 
terms of ENARGAS Note No. 106/2017, on the allocation to be given to the amounts required. In accordance with 

134 

the ENARGAS  criteria,  if  the  sworn  statements meet the requirements  of MINEM Resolution  No. 312—E/2016,  they would  be  sent to the  MINEM 
Hydrocarbons Secretariat in order to arrange for the transfer of the assistance. Likewise, the Resolution set forth that the Licensees could not distribute 
dividends under the terms of Resolution No. 31/2016 of the MINEM. 

On March 31, 2017, Metrogas received the amount of 759 corresponding to MINEM Resolution No. 312—E/2016. 

New gas prices at the TSEP and Metrogas transition tariff schemes 

Through Resolution No. 74—E/2017, the MINEM determined the new natural gas prices at the TSEP applicable from April 1, 2017 to the categories of 
users indicated therein. Moreover, it determined the new prices at the TSEP, subsidized for natural gas Residential users who register a saving in their 
consumption equal or superior to fifteen percent (15%) with respect to the same period in 2015. These new prices in the TSEP have been contemplated 
in ENARGAS Resolution No. 4,356/2017. 

MINEM Resolution No. 474-E/2017 determined the new Gas prices at the TSEP as of December 1, 2017. In addition, a 10% discount is established on 
the Gas price for all categories of Residential users who register a saving in their consumption equal to or greater than 20% with respect to the same 
period in 2015, and it establishes that the bonus corresponding to the Social Tariff beneficiaries will be equivalent to: i) 100% of the Natural Gas price 
on the consumption block base determined by Resolution; and ii) 75% of the price of Natural Gas on a surplus consumption block of equal volume to 
that determined in paragraph i). Consumptions over  and above the block indicated in paragraph ii) will be paid by 100%. It also establishes that the 
billing resulting from the application of the new tariff schedules must respect the limits established in Article 10 of Resolution No. 212 dated October 6, 
2016 of the MINEM. These new prices in the TSEP have been contemplated in the ENARGAS Resolution No. 131/2017, which approved the Metrogas 
temporary tariff scheme, applicable as of December 1, 2017. 

On August 1, 2018, MINEM Resolution No. 46/2018 was published in the Official Gazette, instructing the Electric Power Under-Secretariat to take the 
necessary measures in order for CAMMESA to implement the competitive mechanisms to assure availability of gas for electricity generation, for each 
basin of origin, that shall be applicable for the valuation of natural gas volumes destined for the generation of electricity to be commercialized in the 
MEM or, in general, destined for the provision of the public service of electricity distribution as of August, 1, 2018. 

Procedure for the compensation of the lower revenues that the Distributors receive from their users for benefits and / or bonuses and for higher costs 
of unaccounted gas 

MINEM Resolution No. 508-E/2017, published on December 29, 2017, established the procedure for the compensation of the lower revenues that the 
Licensees  of  the  Natural  Gas  Distribution  Service  through  Networks  receive  from  their  users,  as  a  product  of:  (i) the  application  of  benefits  and/or 
discounts to users arising from the regulations in force in the tariff area of the distribution service of natural gas through networks, and (ii) the higher 
UNG costs compared to those established for its recognition in the rates, applicable as of January 1, 2018. 

Note from the ENARGAS on deferred collection to residential users 

On  August 25,  2017,  the  ENARGAS  issued  some  Notes  instructing  the  Licensees  of  the  Gas  Distribution  Service  (“Distributors”),  by  virtue  of  the 
presentation received from the MINEM, and in relation to the invoices to be issued from August 25, 2017 and until October 31, 2017 for residential 
users,  to  contemplate  a  fifty  percent  (50%)  payment  deferral  of  the  total  amount  of  the  settlement  corresponding  to  the  billing  period,  without  any 
interest. According to this instruction, the amounts subject to deferral must be included in the first invoice issued after October 31, 2017 in accordance 
with the guidelines related to the issuance of Public Service Settlement receipts for bimonthly invoicing with monthly payment obligations currently in 
force, i.e., in two equal and consecutive monthly installments. Such deferral is  not applicable to residential users  who are beneficiaries of the Social 
Tariff. 

The Notes sent by the ENARGAS also contemplate that, if there is a financial impact on the Distributors’ income by virtue of such deferral, such impact 
will be timely evaluated and assumed by the Argentine Government through the corresponding budgetary management. 

On September 20, 2017, YPF submitted a note to the MINEM (with a copy to ENARGAS), requesting the intervention of the MINEM so that it adopts 
the necessary measures to prevent the instruction given by the ENARGAS from being misinterpreted by some Distributors to place on the Producers, 
such as YPF, the financial impact that such a measure could cause, through the unilateral postponement of the payment obligations by the Distributors. 
As of the date hereof, the note submitted by YPF is yet to be answered. 

135 

As a result of the changes introduced through MINEM Resolution No. 474—E/2017 and ENARGAS Resolutions No. 131/2017 and No. 132/2017, and 
the guidelines established in the Terms and Conditions MINEM, Resolution No. 508-E / 2017 was published on December 29, 2017, which establishes 
the procedure for the compensation of the lower revenues that the Licensees of the Natural Gas Distribution Service through Networks receive from 
their users, as a result of: (i) the application of benefits and / or discounts to users resulting from the regulations in force regarding the tariffs applicable 
to  the  natural  gas  distribution  service  through  networks;  and  (ii) the  higher  costs  of  the  Unaccounted  Natural  Gas  (“UNG”)  with  respect  to  those 
established for its recognition in the tariffs. 

In  accordance  with  the  compensation  procedure,  the  Distribution  Licensees  must  inform  to  the  ENARGAS  within  the  terms  established  therein  and 
based on the annualized monthly consumption and as a sworn statement, the amounts required to compensate the aforementioned differences. The same 
information regime is adopted in relation to UNG. 

Thus,  in  order  to  calculate  compensations  for  the  amount  that  they  do  not  receive  for  the  discounts  in  billing  as  well  as  for  the  UNG  differences, 
compensation is established resulting from the difference between the purchase price to the natural gas producer and the sale to its customers. 

Benchmark prices for the butane commercialization chain 

On April 5, 2017, the Secretariat of Hydrocarbon Resources published Resolution No. 56-E/2017 in the Official Gazette, establishing new maximum 
benchmark  prices  for  the  different  segments  of  the  butane  commercialization  chain  to  be  bottled  in  10,  12  and  15  kg  bottles  under  the  Household 
Program  (Decree  No. 470/2015  and  former  Energy  Secretariat  Resolution  No. 49/2015),  and  modifying  the  benchmark  prices  established  in  former 
Energy Secretariat Resolution No. 70/2015. The new maximum benchmark prices for the Company are Ps. 2,568/TN for butane and Ps. 2,410/TN for 
propane. For fractionators such as YPF GAS S.A., the prices established by Resolution No. 56-E/2017 are Ps. 63.89 for 10 kg bottles, Ps. 76.67 for 12 
kg bottles and Ps. 95.84 for 15 kg bottles. 

On June 7, 2017, the Secretariat of Hydrocarbon Resources published Resolution No. 75/2017 in the Official Gazette, which modified the regulations 
applicable  to  the  Household  Program  (former  Energy  Secretariat  Resolution  No. 49/2015)  and  provides  that  the  adjustment  of  benchmark  prices 
applicable to the different segments of the butane commercialization chain to be bottled in 10 and 12 kg bottles will not be implemented automatically 
in quarterly periods. Instead, those adjustments will be made at the discretion of the Secretariat of Hydrocarbon Resources in its capacity as enforcement 
authority of the Household Program. In addition, the resolution establishes that the adjustment of benchmark prices for LPG producers and fractionators 
on account of the Comprehensive Tariff Review established by the Household Program in its regulations will take place only after the prior analysis of 
cost variations and their incidence, and taking into account regional, distribution and logistical factors. 

MINEM Resolution No. 287-E/2017, published on December 1, 2017, established new maximum benchmark prices and compensations for butane and 
propane  producers  effective  from  December 1,  2017,  and  introduced  amendments  to  the  Annex  to  the  Regulation  of  the  Bottle-to-Bottle  Program 
approved by Resolution No. 49/2015, among which, it is prohibited to charge the distributors for any additional service whatever its denomination, if in 
doing so the maximum benchmark prices and the maximum allowed deviations are exceeded. 

On March 28, 2018, Disposition No. 5/2018 of the Under-Secretariat of Hydrocarbon Resources was published, establishing new maximum reference 
prices for the commercialization of butane destined for sale of bottled LPG, in force as of April 1, 2018. 

Hydrocarbon  Resources  Under-Secretariat  Disposition  No. 5/2018  published  in  the  Official  Gazette  on  March 28,  2018,  established  new  maximum 
benchmark prices and compensations for butane and propane producers effective from April 1, 2018. 

Natural gas export administration and domestic supply priorities 

In March 2004, the former Argentine Secretariat of Energy issued S.E. Resolution No. 265/04 adopting measures intended to ensure the adequate 

supply of natural gas to the domestic market and regulate its consequences on electricity wholesale prices. Among the measures adopted were: 

•

the suspension of all exports of surplus natural gas; 

136 

•

•

•

the suspension of automatic approvals of requests to export natural gas; 

the  suspension  of  all  applications  for  new  authorizations  to  export  natural  gas,  filed  or  to  be  filed  before  the  former  Argentine  Secretariat  of 
Energy; and 

the authorization to the Undersecretariat of Fuels to create a rationalization plan of gas exports and transportation capacity. 

In March 2004, the Undersecretariat of Fuels, pursuant to the authority given to it under S.E. Resolution No. 265/04, issued S.S.C. Regulation 
No. 27/04 establishing a rationalization plan of gas exports and transportation capacity. Among other things, S.S.C. Regulation No. 27/04 established a 
limit on natural gas export authorizations, which, absent an express authorization by the Undersecretariat of Fuels, may not be executed for volumes 
exceeding exports registered during 2003. 

In June 2004, the former Argentine Secretariat of Energy issued S.E. Resolution No. 659/04, which established a new program to assure natural 
gas  supply  to  the  domestic  market  (which  substitutes  for  the  program  created  by  S.S.C.  Regulation  No. 27/04).  Under  S.E.  Resolution  No. 659/04 
(amended  by  S.E.  Resolution  No. 1,681/04),  natural  gas  exports  may  be  restricted  due  to  shortages  of  natural  gas  in  the  domestic  market,  because 
exporting  producers  may  be  required  to  supply  additional  volumes  of  natural  gas  to  the  domestic  market  beyond  those  that  they  are  contractually 
committed to supply. The export of natural gas under current export permits is conditioned on the fulfillment of additional supply requirements imposed 
on exporting producers by governmental authorities. 

This program was further amended and supplemented by S.E. Resolution No. 752/05 issued by the former Argentine Secretariat of Energy in May 
2005, which further reduced the ability of producers to export natural gas, and created a mechanism under which the former Argentine Secretariat of 
Energy  may  require  exporting  producers  to  supply  additional  volumes  to  domestic  consumers  during  a  seasonal  period  (“Permanent  Additional 
Supply”), which volumes of natural gas are also not committed by the exporting producers. Based on the provisions of Rule No. 27/04, S.E. Resolution 
No. 659/04  and  S.E.  Resolution  No. 752/05,  the  former  Argentine  Secretariat  of  Energy  and/or  the  Undersecretariat  of  Fuels  have  instructed  us  to 
redirect natural gas export volumes to the internal market, thereby affecting natural gas export commitments. We have challenged the validity of the 
aforementioned  regulations  and  resolutions  and  have  invoked  the  occurrence  of  a  force  majeure  event  under  the  corresponding  natural  gas  export 
purchase  and  sale  agreements.  The  counterparties  to  such  agreements  have  rejected  our  position.  See  “Item  8.  Financial  Information—Legal 
Proceedings.” 

S.E. Resolution No. 752/05 also establishes (i) a special market, open and anonymous, for compressed natural gas stations to purchase natural gas 
under regulated commercial conditions, with the demand being ensured by the former Argentine Secretariat of Energy through Permanent Additional 
Supply  required  of  exporting  producers,  and  (ii) a  mechanism  of  standardized  irrevocable  offers  for  electric  power  generators  and  industrial  and 
commercial  consumers  to  obtain  supply  of  natural  gas,  with  the  demand  being  ensured  by  the  former  Argentine  Secretariat  of  Energy  through  the 
issuance of the Permanent Additional Supply mentioned above. 

Pursuant to the standardized irrevocable offers procedure mentioned above, which operates at the MEG, any direct consumer may bid for a term 
gas purchase at the export average gas price, net of withholdings by basin. The volume necessary to satisfy the standardized irrevocable offers which 
have not been satisfied will be required as a Permanent Additional Supply only until the end of the seasonal period during which the unsatisfied requests 
should be made (October–April or May–September). Such Permanent Additional Supply will be requested from the producers that export gas and that 
inject the natural gas from the basins that are able to supply those unsatisfied irrevocable offers. S.E. Resolution No. 1,886/06, published on January 4, 
2007, extended the term of effectiveness of this mechanism of standardized irrevocable offers until 2016, and empowered the Undersecretariat of Fuels 
to  suspend  its  effectiveness  subject  to  the  satisfaction  of  internal  demand  of  natural  gas  achieved  by  means  of  regulations,  agreements  or  due  to  the 
discovery of reserves. 

By means of S.E. Resolution No. 1,329/06, later supplemented by S.S.C. Note No. 1,011/07, the former Argentine Secretariat of Energy required 
producers  to  give  first  priority  in  their  injections  of  natural  gas  into  the  gas  pipelines  to  certain  preferential  consumers  and  obligated  transportation 
companies to guarantee these priorities through the allocation of transportation capacity. In general, these regulations subordinate all exports of natural 
gas to the prior delivery of natural gas volumes that are sufficient to satisfy domestic market demand. 

Also, beginning during the severe Argentine winter in 2007 and continuing thereafter, we and most gas producers, as well as the transportation 
companies  in  Argentina,  received  instructions  from  the  government  to  decrease  exports,  except  for  certain  volumes  addressed  to  satisfy  Chilean 
residential consumption and other specific consumption. 

National Decree No. 893/2016, dated July 25, 2016, determined that MINEM would be empowered to regulate the award of export permits for the 
following  purposes:  i)  to  deliver  assistance  with  natural  gas  emergency  situations  of  foreign  countries,  and  ii)  to  replace  natural  local  transport 
restrictions by means of utilizing foreign transportation infrastructure to ease transportation of natural gas within the Argentine market and allow for an 
increase in local production. 

137 

On January 8, 2017, export duties on hydrocarbon exports established by Law No. 26,732 ceased to be enforceable. Thereafter, there will be no 

export duties on natural gas exports. 

On January 13, 2017, MINEM published Resolution No. 8/2017 regulated National Decree No. 893/2016, establishing an especial procedure to 
grant  natural  gas  export  permits  subject  to  import  commitments.  Solicitors  for  both  types  of  permits  will  have  to  commit  to  import  the  volumes  of 
natural  gas  exported  and  to  indemnify  the  Argentine  government  for  breaching  such  obligation,  including  the  payment  of  150%  of  the  import  costs 
incurred by the Argentine government to replace the outstanding natural gas. Permits would be extended for a maximum period of two years and are 
subject to possible termination in the event that public interest makes it convenient for local market supply in accordance with MINEM’s criteria. 

On November 27, 2017, MINEM published Decree No. 962/2017 in the Official Gazette, which, among other aspects, modifies Article 3 of the 
Regulatory Decree of the gas law, establishing the following principles for export authorizations: 1) export authorizations will be issued by the MINEM 
once  the  applications  have  been  evaluated;  2)  the  export  agreements  that  imply  the  construction  of  new  facilities  and/or  new  connections  to  the  gas 
pipelines,  or  the  use  of  any  of  the  existing  systems,  or  other  transportation  alternatives,  will  be  approved  by  the  MINEM  with  the  intervention  of 
ENARGAS; 3) the authorizations issued by the MINEM may provide for the export of gas surplus to the amounts established therein, provided they are 
subject to interruption when there are internal supply problems. 

In this case, it will not be necessary to obtain the approval of each surplus export transaction in the authorization, only to submit to ENARGAS, 
for informative purposes only, the respective contract evidencing the existence of a condition relating to the possibility of interruption should arise and 
the absence of compensation in case of such interruption. The modifications introduced by Decree No. 962/2017 do not modify the regime of temporary 
export permits subject to export commitments provided for in Decree No. 893/2016. 

On August 22, 2018, the former Ministry of Energy and Mining issued Resolution No. 104/2018, later modified by Resolution No. 9/2018 of the 
SGE, by which: i) it established a new procedure to obtain authorizations to export natural gas, ii) it abrogated Resolution No. 299/98 clarifying that any 
export  permit  awarded  under  such  resolution  would  have  to  comply  with  the  new  procedure;  iii)  it  abrogated  former  Energy  and  Mining  Secretary 
Resolutions  No. 131/2001,  265/2004,  883/2005  and  former  Ministry  of  Energy  and  Mining  Resolution  No. 8/2017;  and  iv)  it  delegates  to  the 
Hydrocarbon Resources Sub-Secretary the power to exercise the tasks described in the new procedure. 

Resolution  No. 104/2018  provided  that  in  the  case  of  export  requests  from  a  project  included  in  MINEN  Resolution  No.  46-E/2017 
(Unconventional Gas Production Stimulus Program), the quantities of gas would not be computed as part of and/or within the production included under 
the mentioned Program. 

On September 4, 2018 Decree No. 793/2018 was published in the Official Gazette. See “—Export Taxes.” 

On  November 14,  2018,  in  the  Official  Gazette  was  published  the  SGE  Resolution  No. 95/2018  by  which  it  granted  YPF  a  permit,  under 
Resolution  No. 104/2018,  to  export  natural  gas  to  Innergy  Soluciones  Energéticas  S.A.  on  interruptible  conditions  for  a  volume  of  1,500,000  cm/d 
during the summer season. 

On  December 14,  2018,  in  the  Official  Gazette  was  published  the  S  G  E  Resolution  No. 262/2018  by  which  it  granted  YPF  a  permit,  under 

Resolution No. 104/2018, to export natural gas to Colbún S.A. on interruptible conditions for a volume of 1,500,000 cm/d during the summer season. 

On  December 21,  2018,  in  the  Official  Gazette  was  published  the  SGE  Resolution  No. 313/2018  by  which  it  granted  YPF  a  permit,  under 
Resolution No. 104/2018, to export natural gas to Aprovisionadora Global De Energía Sociedad Anónima (AGESA) on interruptible conditions for a 
volume of 1,500,000 cm/d during the summer season. 

On  December 27,  2018,  in  the  Official  Gazette  was  published  the  SGE  Resolution  No. 339/2018  by  which  it  granted  YPF  a  permit,  under 
Resolution No. 339/2018, to export natural gas to Enel Generación Chile Sociedad Anónima on interruptible conditions for a volume of 2,000,000 cm/d 
during the summer season. 

On December 4, 2018, Law No. 27,467 relating to the National Budget for 2019 was published. Sections 81 and 82 thereof respectively establish 
i) that the PEN may fix export duties until December 31, 2020 which rate may not exceed 30% of the taxable value or the official FOB price, with a 
maximum limit of 12% for those goods that were not subject to export duties as of September 2, 2018 or that were taxed with a 0% rate as of that date, 
and ii) that Decree No. 793/18 continues in full force and effect.

Liquefied petroleum gas 

Law  No. 26,020,  enacted  on  March 9,  2005,  sets  forth  the  regulatory  framework  for  the  industry  and  commercialization  of  LPG.  This  law 
regulates  the  activities  of  production,  bottling,  transportation,  storage,  distribution,  and  commercialization  of  LPG  in  Argentina  and  declares  such 
activities to be of public interest. Among other things, the law: 

1.

2.

creates the registry of LPG bottlers, obliging LPG bottlers to register the bottles of their property; 

protects the trademarks of LPG bottlers; 

• creates a reference price system, pursuant to which the SGE shall periodically publish reference prices for LPG sold in bottles of 45 kilograms or 

less; 

•

requires the SGE to comply with the following tasks: (i) create LPG transfer mechanisms, in order to guarantee access to the product to all the 
agents of the supply chain; (ii) establish mechanisms for the stabilization of LPG prices charged to local LPG bottlers; and (iii) together with the 
CNDC, analyze the composition of the LPG market and its behavior, in order to establish limitations on market concentration in each phase, or 
limitations  to  the  vertical  integration  throughout  the  chain  of the  LPG  industry  (such  limitations  apply  to  affiliates,  subsidiaries  and  controlled 
companies); 

• grants open access to LPG storage facilities; and 

• creates  a  fiduciary  fund  to  finance  bottled  LPG  consumption  for  low-income  communities  in  Argentina  and  the  extension  of  the  natural  gas 
distribution  network  to  new  areas,  where  technically  possible  and  economically  feasible.  The  fiduciary  fund  is  funded  through  the  following 
mechanisms: (i) penalties established by Law No. 26,020, (ii) assignments from the General State Budget, (iii) funds from special credit programs 
that  may  be  arranged  with  national  or  international  institutions,  and  (iv) funds  that  may  be  assessed  by  the  SGE  on  participants  in  the  LPG 
industry. 

The  former  Argentine  Secretariat  of  Energy  established,  through  several  subsequent  resolutions,  reference  prices  applicable  to  sales  of  LPG 
bottles of less than 45 kilograms, and to sales of bulk LPG exclusively to LPG bottlers. Also, the former Argentine Secretariat of Energy approved the 
method  for  calculating  the  LPG  export  parity,  to  be  updated  monthly  by  the  Undersecretariat  of  Fuels.  In  2007,  the  former  Argentine  Secretariat  of 
Energy increased the LPG volumes to be sold to bottlers at the reference prices set forth in the unconventional above mentioned resolutions. 

Disposition  No. 168/04  of  the  Under-Secretariat  of  Fuels  requires  companies  intending  to  export LPG  to  first  obtain  an  authorization  from  the 
former Argentine Secretariat of Energy. Companies seeking to export LPG must first demonstrate that the local demand is satisfied or that an offer to 
sell LPG to local demand has been made and rejected. 

On September 19, 2008, the Secretariat of Energy and Argentine LPG producers entered into the Complementary Agreement which, among other 
objectives, seeks to stabilize the price of LPG in the domestic market. The Complementary Agreement applies only to LPG sold to bottlers that declare 
their intention to bottle such LPG in LPG bottles of 10, 12 or 15 kilograms. The Complementary Agreement requires LPG producers to supply LPG 
bottlers with a prescribed volume and accept the price per ton set forth in the Complementary Agreement. The Complementary Agreement was then 
extended in the following years until 2015 with certain modifications in quantities and prices to be provided every year. 

On April 7, 2015, Resolution No. 73 of the former Argentine Secretariat of Energy terminated the fiduciary agreement to which YPF was a party 
as a natural gas producer, contributing funds for the payment of compensation for LPG producers and bottlers. As a result, natural gas producers that 
were parties to the Complementary Agreement are no longer required to contribute funds. At the same time, a new program for the provision of bottled 
LPG  at  reference  prices  was  established  by  Decree  No. 470/2015  dated  March 31,  2015.  This  decree  established  that  LPG  producers  and  bottlers 
provide LPG at reference prices in the domestic market, gradually increasing the volumes provided in 2014. 

This new program for the provision of bottled LPG has been modified by different succeeding resolutions which modified the reference prices and 
the  methodology  for  reference  price  future  updates,  among  other  changes.  These  resolutions  are:  Hydrocarbon  Secretary  Resolution  No.  56-E/2017, 
No. 75/2017 and MINEM Resolution No. 287-E/2017.

Electricity 

By means of Decree No. 134/2015, published in December 2015, the National Executive Office declared the National Electric System Emergency 

through December 31, 2017. This decree instructs the Minister of Energy to develop and propose measures and to ensure adequate power supplies. 

The  following  regulations  were  issued  by  the  Ministry  of  Energy  and  its  Secretariat  of  Electric  Power  (“SEE”)  as  measures  to  the  National 

Electric System Emergency among others: MINEM No. 6/2016; SEE No. 21/2016; SEE No. 22/2016; SEE No. 19/2017 and SEE No. 256/2017. 

Through  Resolution  No. 06/2016,  published  in  January  2016,  MINEM  established  new  seasonal  reference  prices  of  power  and  energy  for  the 
MEM  from  February 1,  2016  to  April 30,  2016.  The  resolution  also  establishes  a  stimulus  plan,  with  reference  prices  for  residential  consumers  that 
reduce their consumption over the same month in 2015, and a social tariff. 

Through Resolution SEE No. 21/2016, dated February 2016, the Secretariat of Electric Power called for a public bid for the installation of new 
thermic  power  generation  and  associated  electric  energy  production  that  may  confirm  availability  for  summer  2016/2017,  winter  2017  and  summer 
2017/2018. 

Through Resolution No. 41/2016, published in January 2016, which modified Resolution No. 6/2016, MINEM established new seasonal reference 
prices of power and energy in the MEM from May 1, 2016 to October 31, 2016. It also confirms the applicability of the stimulus plan and social tariff 
until October 31, 2016. 

Through Resolution No. 20/2017, published in January 2017, MINEM established, among other things, new seasonal reference prices of power 

and energy in the MEM from February 1, 2017 to April 30, 2017. 

National  Decree  No. 531/2016,  dated  March 31,  2016,  regulates  Law  No. 27,191  (regarding  the  national  incentive  for  the  use  of  renewable 
sources to generate electricity) and, among other things, establishes that “big consumers” shall contract for or co-generate renewable energy to comply 
with the obligation to consume 8% of its electricity from renewable sources, by December 2017. If such requirement is not met, the “big consumers” 
will be punished with a fine equal to the variable cost of producing the unmet electricity by a thermos-electrical power plant with imported gasoil fuel. 

Argentine  Secretariat  of  Electric  Power  Resolution  No. 22/2016,  dated  March 30,  2016,  modified  Resolution  No. 482/2015,  adjusting  the 

remuneration components for power generators that adhered to Resolutions No. 95/2013, 529/2014 and 482/2015, retroactively to February 2016. 

MINEM Resolution No. 41/2016, dated April 13,  2016, establishes new prices on the natural gas at TSEP for each basin which would then be 
acquired  for  electric  generation  purposes  and  therefore  commercialized  within  the  MEM  or  generally  destined  to  satisfy  the  electricity  distribution 
services. 

SEE Resolution No. 420/2016, published on November 2016, called for projects which may contribute to the electric market cost reduction and 

the increase in the Argentine electric system reliance. 

Through Resolution No. 19/2017, published in January 2017, MINEM, through its Secretariat of Electric Power established a new set of prices for 
installed electricity generation facilities for any new contracts regarding guaranteed energy offers. Prices have been dollarized and represent an increase 
with respect to those in force in 2016. Resolution No. 19/2017 also determined a stimulus mechanism towards operative efficiency. 

Through Resolution No. 256/2017, published in April 2017, MINEM established, among other things, new seasonal reference prices of power and 

energy in the MEM from May 1, 2017 until October 31, 2017. 

Through  Resolution  SEE  No. 287/2017,  dated  May  2017,  within  the  framework  of  Resolution  No. 420/2016  the  Electric  Power  Secretariat 

established a public bid for projects willing to sell electricity produced by co-generation or close cycle projects. 

140 

Through  Resolution  No.1091/2017,  published  in  November  2017,  MINEM  established,  among  other  things,  new  seasonal  reference  prices  of 
power and energy in the MEM from November 1, 2017 to April 30, 2018. It also establishes the Social Tariff Subsidy and the Stimulus Plan discounts 
for the period running from December 1, 2017 through April 30, 2018. 

Electricity Secretary Resolution No. 926-E/2017, dated October 17, 2017 authorized CAMMESA the signature of purchase power agreements for 
YPF EE co-generation project in La Plata, Buenos Aires Province and YGEN Eléctrica S.R.L. close cycle project in El Bracho, Province of Tucumán, 
awarded in Resolution No. 287 public bid framework. 

On  November 7,  2018,  SGE  Resolution  No. 70/2018  was  published  in  the  Official  Gazette  which  allows  Generators,  Co-generators  and  Self-
generators from MEM to buy their own fuel for power generation. The fuel costs will be recognized by the mechanism of Production Variable Costs 
established by CAMMESA, who will continue to buy fuels for those generators who do not or cannot exercise the abovementioned purchase. 

On March 1, 2019, Resolution No. 1/2019 of the Secretary of Renewable Resources and Electric Market which derogated Resolution No. 19/2017 
of  the  former  Secretary  of  Electric  Energy,  effective  as  of  March 1,  2019,  and  among  other  aspects  provided  for  new  mechanisms  for  payment  of 
guaranteed  power  availability  and  generation  by  Generators,  Co-generators  and  Self-generators  from  MEM  (excluding  binational  hydroelectric 
generators,  nuclear  generators  and  Generators,  Co-generators  and  Self-generators  from  MEM  whose  generating  units  had  been  committed  as  part  of 
agreements for purposes of supplying the MEM from such regime). The prices for power and generation during the six months during which electric 
demand  is  lower  which  were  approved  by  Resolution  No. 1/2019  are  approximately  20%  lower  in  dollar  terms  than  those  set  forth  in  Resolution 
No. 19/2017. 

Argentine Environmental Regulations 

The  enactment  of  Articles  41  and  43  in  the  National  Constitution,  as  amended  in  1994,  as  well  as  new  federal,  provincial  and  municipal 
legislation,  has  strengthened  the  legal  framework  dealing  with  damage  to  the  environment.  Legislative  and  government  agencies  have  become  more 
vigilant in enforcing the laws and regulations regarding the environment, increasing sanctions for environmental violations. 

Under the amended Articles 41 and 43 of the National Constitution, all Argentine inhabitants have both the right to an undamaged environment 
and a duty to protect it. The primary obligation of any person held liable for environmental damage is to rectify such damage according to and within the 
scope  of  applicable  law.  The  federal  government  sets  forth  the  minimum  standards  for  the  protection  of  the  environment  and  the  provinces  and 
municipalities establish specific standards and implementing regulations. 

Federal,  provincial  and  municipal  laws  and  regulations  relating  to  environmental  quality  in  Argentina  affect  our  operations.  These  laws  and 
regulations set standards for certain aspects of environmental quality, provide for penalties and other liabilities for the violation of such standards, and 
establish remedial obligations in certain circumstances. 

In general, we are subject to the requirements of the following federal environmental regulations (including the regulations issued thereunder): 

• National Constitution (Articles 41 and 43); 

• Law No. 25,675 on National Environmental Policy; 

• Law No. 25,612 on Integrated Management of Industrial and Service Industry Waste; 

• Law No. 24,051 on Hazardous Waste; 

• Law No. 20,284 on Clean Air; 

• Law No. 25,688 on Environmental Management of Waters; 

• Law No. 25,670 on the Management and Elimination of Polychlorinated Biphenyls; 

• Criminal Code; and 

•

the Argentine Civil and Commercial Code, which sets forth the general rules of tort law. 

141 

These  laws  address  environmental  issues,  including  limits  on  the  discharge  of  waste  associated  with  oil  and  gas  operations,  investigation  and 
cleanup  of  hazardous  substances,  workplace  safety  and  health,  natural  resource  damages  claims  and  toxic  tort  liabilities.  Furthermore,  these  laws 
typically require compliance with associated regulations and permits and provide for the imposition of penalties in case of non-compliance. 

In  addition,  we  are  subject  to  various  other  provincial  and  municipal  regulations,  including  those  relating  to  gas  venting,  oil  spills  and  well 

abandonment, among other matters. 

By Resolution No. 404/94, the former Argentine Secretariat of Energy amended Resolution No. 419/93, and created the Registry of Independent 
Professionals  and  Safety  Auditing  Companies  (Registro  de  Profesionales  Independientes  y  Empresas  Auditoras  de  Seguridad),  which  may  act  with 
respect to areas of hydrocarbons storage, oil refineries, gas stations, fuel commercialization plants and plants for fractionation of LPG in containers or 
cylinders.  The  Resolution  provides  that  external  audits  of  oil  refineries,  gas  stations  and  all  fuel  storage  plants  must  be  carried  out  by  professionals 
registered in the Registry. Domestic fuel manufacturing companies and companies that sell fuels are prohibited from supplying these products to any 
station failing to comply with its obligations. Penalties for failure to perform the audits and remedial or safety tasks include the disqualification of plants 
or  gas  stations.  In  addition,  a  set  of  obligations  was  established  regarding  underground  fuel  storage  systems,  including  a  mechanism  for  instant 
notification in cases of loss or suspicion of loss from the storage facilities. 

On July 19, 2001, the Secretariat of Environmental Policy of the province of Buenos Aires issued Resolution No. 1,037/01 ordering us to clean up 
certain  areas  adjacent  to  the  La  Plata  refinery.  The  resolution  was  appealed  through  an  administrative  procedure  which  has  not  yet  been  resolved. 
Nevertheless,  we  have  commenced  certain  actions  in  order  to  identify  potential  technical  solutions  for  the  treatment  of  the  historical  contamination, 
while  reserving  that  the  remediation  must  be  made  by  the  parties  responsible  for  the  environmental  damage.  Under  current  law,  the  Argentine 
government  has  the  obligation  to  indemnify  us  against  any  liability  and  hold  us  harmless  for  events  and  claims  arising  prior  to  January 1,  1991, 
according to the Privatization Law. 

During  2005,  the  former  Argentine  Secretariat  of  Energy,  by  means  of  Resolution  No. 785/05,  created  the  National  Program  of  Hydrocarbons 
Warehousing  Aerial  Tank  Loss  Control,  a  measure  aimed  at  reducing  and  correcting  environmental  pollution  caused  by  hydrocarbons  warehousing-
aerial tanks. 

The description of the material Argentine environmental regulations is only a summary and does not purport to be a comprehensive description of 
the Argentine environmental regulatory framework. The summary is based upon Argentine regulations related to environmental issues as in effect on the 
date of this annual report, and such regulations are subject to change. 

Taxation 

Holders of exploration permits and production concessions are subject to federal, provincial and municipal taxes and regular customs duties on imports. 
The Hydrocarbons Law grants such holders a legal guarantee against new taxes and certain tax increases at the provincial and municipal levels, except 
in the case of a general increase in taxes. 

Pursuant to Sections 57 and 58 of the Hydrocarbons Law, holders of exploration permits and production concessions must pay an annual surface fee that 
is  based  on  acreage  of  each  block  and  which  varies  depending  on  the  phase  of  the  operation,  i.e.,  exploration  or  production,  and  in  the  case  of  the 
former, depending on the relevant period of the exploration permit. On October 17, 2007, the Official Gazette published Executive Decree No. 1,454/07, 
which  significantly  increased  the  amount  of  exploration  and  production  surface  fees  expressed  in  Argentine  pesos  that  are  payable  to  the  different 
jurisdictions  where  the  hydrocarbon  fields  are  located.  Law  No. 27,007  published  in  the  Official  Gazette  on  October 31,  2014  updated  amounts  that 
must be paid pursuant to Sections 57 and 58 of the Hydrocarbons Law. See “—Upstream.” 

In addition, “net profit” (as defined in the Hydrocarbons Law) of holders of permits, or concessions accruing from activity as such holders, might be 
subject to the application of a special 55% income tax. This tax has never been applied. Each permit or concession granted to an entity other than us has 
provided that the holder thereof is subject instead to the general Argentine tax regime, and a decree of the National Executive Office provides that we 
are also subject to the general Argentine tax regime. 

Following  the  introduction  of  market  prices  for  downstream  petroleum  products  in  connection  with  the  deregulation  of  the  petroleum  industry,  Law 
No. 23,966 established a volume-based tax on transfers of certain types of fuel, replacing the prior regime, which was based on the regulated price. Law 
No. 25,745 modified, effective as of August 2003, the mechanism for calculating the tax, replacing the old fixed-value per liter according to the type of 
fuel for a percentage to apply to the sales price, maintaining the old fixed value as the minimum tax. Through Laws No. 26,028 and 26,181, new taxes 
on diesel and gasolines sales have been established. 

142 

See additionally Note 30.a to the Audited Consolidated Financial Statements. 

Reduction in tax rates for fuels 

On December 30, 2014, Decree No. 2,579/2014 set forth a reduction in fuel taxes established by Laws No. 23,966 and 26,181 with respect to diesel and 
unleaded gasoline products. The reductions took effect on January 1, 2015. 

On December 29, 2017, Law No. 27,430 introducing modifications to the fuel tax was published in the Official Gazette as follows (Laws No. 26,028 
and 26,181 were repealed): 

1.

2.

A new tax was created (the so called “CO2 Tax”). This new tax essentially applies to Fuel Oil, coke and coal, as well as the same fuels 
taxed by Law 23,966. 

Starting in March 2018, the fuel tax and CO2 Tax will be calculated as a fixed amount per liter instead of as a percentage of the sales price. 

Export taxes 

Export duties on hydrocarbons were established in 2002 by Law No. 25,561 of Public Emergency, for a term of five years. The regime varied during in 
different periods until it ceased after the second extension expired on January 7, 2017. 

However, on September 4, 2018, Decree No. 793/2018 reinstated customs duties on the export of hydrocarbons. See “Item 3. Key Information—Risk 
Factors—Risks Relating to Argentina.” 

Repatriation of Foreign Currency 

Decree  No. 893/2017,  published  on  November 1,  2017,  completely  revoked  the  different  types  of  requirements  and restrictions  which  were  imposed 
from time to time in Argentina, with respect to the repatriation of foreign currency proceeds derived from exports. 

Particularly  concerning  the  upstream  oil  industry,  Executive  Decree  No. 1,589/89,  had  allowed  us  and  other  companies  engaged  in  oil  and  gas 
production activities in Argentina to freely sell and dispose of the hydrocarbons we produce. Additionally, under Decree No. 1,589/89, we and other oil 
producers were entitled to keep up to 70% of foreign currency proceeds received from crude oil and gas export sales outside of Argentina, but were 
required, at that time, to repatriate the remaining 30% through the exchange markets of Argentina. 

After  that,  Decree  No. 1,722/2011  of  October 26,  2011  had  required  all  oil  and  gas  companies  (including  YPF  to  repatriate  100%  of  their  foreign 
currency export receivables. Although such mandatory requirement imposed by Decree No. 1,722/2011 remained in force and effect until late 2017, its 
practical  application  had  been  substantially  relaxed  during  2016  and  2017,  specially  buy the  Resolution  No.  47-E/2017  (issued  by  the  Argentine 
Secretariat  of  Commerce)  which  for  the  repatriation  of  foreign  currency  export  receivables  had  significantly  extended,  from  30  calendar  days  as  of 
December 2015, up to 10 years on December 2017. 

However,  as  a  result  of  Decree  No. 893/2017  described  in  the  first  paragraph,  complemented  by  the  Argentine  Central  Bank’s  Communication  “A” 
6244, there are currently no requirements regarding mandatory repatriation of foreign currency export receivables.

Our operating profit in 2018 was Ps. 43,780 million, compared to a profit of Ps. 16,073 million in 2017. This increase was attributable to the factors 
explained in “-Principal Income Statement Line Items-Operating profit (loss).” 

Our business is inherently volatile due to the influence of external factors, such as those listed above. Consequently, our past financial condition, 
results  of  operations  and  the  trends  indicated  by  such  results  and  financial  condition  may  not  be  indicative  of  the  financial  conditions,  results  of 
operations or trends in future periods. We will continue to focus on accelerating our shale oil developments following the outstanding results obtained 
during 2018. This was the first year during which the growth of our shale oil production was enough to offset the decline in conventional fields, which 
indicates  our  current  strategy  may  lead  to  sustainable  growth  in  production.  As  explained  in  “Item  5.  Operating  and  Financial  Review  and 
Prospects—Factors  Affecting  Our  Operations—Seasonality”,  it  is  not  reasonable  to  accelerate  shale  gas  production  in  a  scenario  of  excess  supply. 
Therefore, we estimate that we will not see production growth in 2019 (estimated to be around 2% - 3% lower than 2018 on a boe basis) mainly as a 
consequence  of  recent  mature  asset  divestments  in  the  order  of  4.8  mboe  per  day  and  lower  gas  production  than  previously  expected.  We  expect  to 
increase our capital expenditures during 2019 compared to 2018, in an amount of between U.S.$3.5 billion and U.S.$4 billion, mainly focused in our 
Upstream operations. 

Our strategy is to accelerate production in Loma Campana and replicate the success of such area in La Amarga Chica and Bandurria. So far, we 
have obtained positive results in both areas, while we de risk other clusters within our extensive shale oil acreage. Additionally, we will continue to 
focus on our conventional production and to pursue our aim of reducing the natural decline of these fields. 

With regard to our Downstream segment, we know that in an inflationary scenario and with a volatile Argentine peso, the pass-through to pump 
prices is always difficult. While our plan contemplates the aforementioned pass-through, we cannot assure you that we will be successful in doing so. 
We have a unique brand and footprint that we expect will allow us to keep our volumes evolving better than local economic activity. 

See “Item 5. Operating and Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions.” 

Notwithstanding the foregoing, there can be no assurance that our production, costs, prices, volumes of sales or our estimates of future cash flows 
from  operations,  among  other  items,  could  not  be  affected  by  factors  beyond  our  control  and,  as  such,  differ  from  our  estimates.  See  “Item  3.  Key 
Information—Risk Factors.” 

Macroeconomic conditions 

Overview 

Substantially all of our revenues are derived from our operations in Argentina and are therefore subject to prevailing macroeconomic conditions in 
Argentina. Changes in economic, political and regulatory conditions in Argentina and measures taken by the Argentine government have had and are 
expected to continue to have a significant impact on us. 

The  Argentine  economy  has  experienced  significant  volatility  in  past  decades,  characterized  by  periods  of  low  or  negative  growth  and  high 
variable levels of inflation. Inflation reached its peak in the late 1980s and early 1990s. Due to inflationary pressures prior to the 1990s, the Argentine 
currency devalued repeatedly, and macroeconomic instability led to broad fluctuations in the real exchange rate of the Argentine currency relative to the 
U.S. dollar. To address these pressures, past Argentine governments implemented various plans and utilized a number of exchange rate systems. 

In  the  fourth  quarter  of  1998,  adverse  international  financial  conditions  caused  the  Argentine  economy  to  enter  into  a  recession  and  GDP  to 
decrease between 1999 and 2001. By the end of 2001, Argentina suffered a profound deterioration in social and economic conditions, accompanied by 
high political and economic instability. The restrictions on the withdrawal of bank deposits, the imposition of exchange controls, the suspension of the 
payment of Argentina’s public debt and the abrogation of the peso’s one-to-one peg to the dollar (with the consequent devaluation of the peso against 
the dollar) caused a decline in economic activity. Real GDP declined by 10.9% in 2002, annual inflation rose to 41%, the exchange rate continued to be 
highly volatile, and the unemployment rate rose to more than 20%. The political and economic instability not only curtailed commercial and financial 
activities in Argentina but also severely restricted the country’s access to international financing. 

Strong  economic  growth  in  the  world’s  developed  economies,  favorable  raw  material  prices  from  2003  through  the  first  half  of  2008  and  the 
implementation of new macroeconomic policies paved the way for Argentina’s economic recovery. Real GDP grew at an average cumulative rate of 
8.5% between 2003 and 2008. As a result of the crisis in the global economy, Argentina’s real GDP growth

rate decelerated in 2009 to 0.9% but recovered in 2010 and 2011 growing by approximately 9% each year. According to the IMF’s estimates, global 
economic  growth  reached  3.1%  in  2015,  although  the  rate  of  growth  or,  in  some  cases,  contraction,  varied  significantly  from  region  to  region.  On 
March 27, 2014, the Argentine government announced a new method of calculating GDP by reference to 2004 as the base year (as opposed to 1993, 
which was the base reference year under the prior method of calculating GDP). 

After the growth in 2010 and 2011, several factors led to a decrease in growth of the Argentine economy in 2012 and 2013. The growth of the 
global economy was not as strong as expected following the easing of U.S. economic crisis that started in 2007, and financial volatility continued at high 
levels. 

The  decline  in  the  price  of  Brent  crude  from  mid  2015  to  the  end  of  2018,  to  nearly  U.S.$  50  per  barrel,  among  other  things,  presented  a 
complicated international scenario that creates uncertainty about the future performance, including potential downside risks, of developed and emerging 
economies, including Argentina. 

In  2015,  this  decline  resulted  in  an  approximately  U.S.$7  reduction  to  the  domestic  price  per  barrel  compared  to  the  price  in  effect  on 
December 31, 2014. This change stemmed from negotiations between producers and refiners to reduce the domestic price of Medanito and Escalante 
crude  during  January  2015  to  U.S.$77  and  U.S.$63  per  barrel,  respectively.  These  prices  stood  at  U.S.$75  and  U.S.$61,  respectively,  as  of 
November 30, 2015. Average prices of the crude Brent barrel were U.S.$ 71.06, U.S.$ 54.25 and U.S.$ 43.56 for 2018, 2017 and 2016, respectively. 
Nonetheless, there was a decline in the rate during the last quarter of 2018, reaching a value of U.S.$ 50.57 on December 31, 2018. 

Mauricio Macri was elected president of Argentina, and his administration took office on December 10, 2015. The new administration has been facing 
and  continues  to  face  challenges  in  respect  of  Argentina’s  economy,  such  as  reducing  the  rate  of  inflation,  the  devaluation  of  the  Argentine  peso, 
improving the competitiveness of the local industries and normalizing or adjusting prices of certain goods and services, such as electricity and natural 
gas for certain residential consumers of Argentina, agreement with bondholders, reforms in foreign trade operations and tax and social security reforms. 
Some  of  the  measures  necessary  to  meet  these  objectives  were  and  continue  to  be  potentially  unpopular  and  could  generate  political  and  social 
opposition or unrest. 

It  is  difficult  to  predict  the  impact  of  these  and  other  measures  such  as  those  mentioned  below  on  the  Argentine  economy  as  a  whole  and  the 
energy sector in particular, including revisions and reforms to pricing mechanisms for oil and gas and elimination of energy subsidies, as well as other 
policy  changes  that  may  affect  the  energy  sector.  This  includes  decisions  that  the  new  administration  has  already  taken,  such  as  the  elimination  of 
exchange restrictions, the partial adjustment of gas and electricity prices, the intention of liberalization of prices for oil and its main fuel products, or 
future measures it may take to address inflation or changes to the exchange rate. Uncertainty regarding the measures to be taken on the economy could 
further  lead  to  price  volatility  of  Argentine  companies,  including  in  particular  companies  like  ours  in  the  energy  sector,  given  the  high  level  of 
regulation. In addition, there can be no assurance that current government programs and policies that apply to the oil and gas sector will continue to be 
in place in the future. 

In addition, Argentina’s national election for president and vice-president will take place in October 2019, and other relevant local and federal 
elections will also take place in 2019. We cannot guarantee that current programs and policies that apply to the oil and gas sector will continue in place 
in the future. See Item 3. Key Information—Risk Factors— Risks Relating to Argentina —The result of the next presidential and provincial elections 
that will take place in 2019 could generate uncertainty in the Argentine economy and, consequently, in our businesses and the results of our operations”, 
“Item 3. Key Information—Risk Factors—Risks Relating to Our Business—Limitations on local pricing in Argentina may adversely affect our results 
of  operations”  and  “Item  3.  Key  Information—Risk  Factors—Risks  Relating  to  Our  Business—  We  are  exposed  to  the  effects  of  fluctuations  in  the 
prices of oil, gas and refined products.” 

One of the measures taken by the new government was regulate the INDEC. On January 7, 2016 through Decree No. 55/2016, the new leadership 
of INDEC issued a report declaring a “national statistical emergency.” INDEC stated that since 2006 its administration has been irregular and due to that 
they revised the published data from 2005 to 2015. As a result of this revision, the GDP growth rate for 2013 and 2014 was revised from 2.9% to 2.4% 
and  from  0.5%  to  a  decline  rate  of  2.5%,  respectively.  As  of  the  date  of  this  annual  report,  Argentina’s  provisional  GDP  growth  rate  for  2016,  the 
provisional  GDP  growth  rate  for  2017  and  the  preliminary  GDP  growth  rate  for  2018  published  by  INDEC  were  negative  1.8%,  positive  2.7%  and 
negative 2.5%, respectively. 

Throughout  2018,  the  variation  of  certain  macroeconomic  variables  such  as  the  exchange  rate  and  inflation,  as  explained  below,  resulted  in  a 
negative impact in the economic activity level, mostly in the second half of 2018. In addition, the plan agreed upon between the Federal Government 
and IMF, as commented below, which had the intention of containing inflation and the exchange rate, determined the need to act upon the monetary 
policy  in  restrictive  terms,  absorbing  Pesos  from  the  market,  acting  upon  the  interest  rates,  among  others,  which  also  had  consequences  over  the 
consumption and, as such, the economy behavior in general.

During May 2018, the Argentine Government began negotiations with the IMF to obtain a preventive financial support, which would mitigate the 
pressure on the federal reserves and the exchange rate at lower interest rate, in an international context marked by the rising cost of credit. On June 20, 
2018, a three-year stand-by agreement to Argentina for an amount of U.S.$ 50.0 billion was approved by the Executive Board of the IMF. During 2018, 
a disbursement of U.S.$ 15.0 billion was made to Argentina, allowing to the Government the use of U.S.$ 7.5 billion to support the Argentine budget. 
On  September 26,  2018,  Argentina  published  a  new  agreement  with  the  IMF.  This  new  agreement  supported  the  three-year  stand-by  agreement, 
approved on June 20, 2018 and includes an increase in available IMF funds of U.S.$ 19.0 billion through the end of 2019. It also raises the maximum 
loan amount available, to U.S.$ 57.1 billion through 2021. Under this new schedule, the expected disbursements through the end of 2018 were raised 
from  U.S.$  6 billion  to U.S.$ 13.4 billion. In  April  2019,  Executive Board of  the  IMF  will  plan  the following disbursement. We  cannot provide  any 
assurances as to the impact of the loan subscribed with the IMF on the Argentine economy or on our economic, financial or other condition, or on our 
results and those of our operations and businesses. 

The  official  exchange  rate  of  the  Argentine  peso  to  the  U.S.  dollar  as  of  December 31,  2017,  the  peso  fell  to  Ps.  18.77  per  U.S.$1.00,  a 
devaluation of approximately 18.4% compared to the rate as of the end of 2016. During 2018, the Argentine peso declined approximately 101.4%. As of 
December 31, 2018, the Argentine peso fell to Ps 37.81 per U.S. dollar 1,00. As of March 28, 2019, the peso was valued at Ps. 43.59 per U.S.$1.00, an 
increase of approximately 15.3% compared to December 31, 2018. 

Argentina has confronted and continues to experience inflationary pressures. According to inflation data published by INDEC, from 2008 to 2013, 
the  Argentine  consumer  price  index  (“CPI”)  increased  7.2%,  7.7%,  10.9%,  9.5%,  10.8%  and  10.9%,  respectively,  and  the  wholesale  price  index 
increased  8.8%,  10.3%,  14.5%,  12.7%,  13.1%  and  14.7%,  respectively.  Before  the  new  administration  took  office,  certain  private  sector  analysts 
believed that inflation was significantly higher than the rate published by INDEC. In 2014, the Argentine government established a new consumer price 
index known as the IPCNU that more broadly reflects consumer prices by considering price information from the 24 provinces of the country, divided 
into six regions. According to INDEC, the IPCNU increased 23.9% in 2014. In 2015, the new administration of INDEC published an alternative CPI 
that showed an increase of 26.9%. In 2016, the alternative CPI, from January to April, increased 4.1%, 4.0%, 3.3% and 6.5%, respectively, and from 
May to December, a new CPI was published that showed increases of 4,2%, 3.1%, 2.0%, 0.2%, 1.1%, 2.4%, 1,6% and 1.2% respectively. In 2017 and 
2018, the CPI increased 24.8% and 47.6% respectively. In January and February 2019, the CPI increased 2.9% and 3.8% respectively. 

The  wholesale  price  index  increased  34.5%,  18.8%  and  73.5%  in  2016,  2017  and  2018,  respectively.  In  January  and  February  2019,  the 

provisional wholesale price index increased 0.6% and 3.4%, respectively. 

As mentioned before, inflation has increased significantly during 2018 and the three-year cumulative inflation has exceeded 100%, which is the 
quantitative  reference  established  by  IAS  29  Financial  Reporting  in  Hyperinflationary  Economies.  As  a  result,  Argentina  is  now  considered  as  a 
hyperinflationary economy. Although the application of IAS 29 does not directly affect YPF because its functional currency is the US dollar, it does 
affect the investments that the Company has in its subsidiaries, associates and joint ventures whose functional currency is the Peso, all of which have 
restated  their  financial  statements.  See  Note  2.a).  “Basis  of  preparation  of  the  consolidated  financial  statements”  and  “Financial  information  of 
subsidiaries, associates and joint ventures in hyperinflationary economies” to the Audited Consolidated Financial Statements. 

In such context, as explained in its Monetary Policy brochure of January 2019, the Central Bank established a new monetary policy in the end of 
September  2018 with  views to  resume the path to  reducing inflation, setting  aside  the  former  inflation  goal regime.  According  to the new  policy,  in 
effect  as  of  October 1,  2018,  the  Argentine  Central  Bank  committed  not  to  increase  the  monetary  base  until  December  2019.  This  monetary  base 
objective  is  complemented  by  the  definition  of  intervention  and  non-intervention  exchange  rate  zones.  The  non-intervention  zone  was  defined  as  of 
October with a lower limit exchange rate of 34 pesos per dollar and the higher limit was set at 44 pesos per dollar, which are to be adjusted daily at a 
rate of 3% a month in the last quarter of 2018, 2% a month in the first quarter of 2019 (based on the limits in effect as of December 31, 2018) and 1.75% 
a month in the second quarter of 2019 (based on the limits in effect as of March 31, 2019), with updates in later months to be established in its future 
decisions. Within the non-intervention zone, the exchange rate fluctuates freely. During the last quarter of 2018, the exchange rate has remained within 
the non-intervention zone, although approaching the lower limit as the demand for pesos increased. 

See  “Item  3.  Key  Information—Risk  Factors—Risks  Relating  to  Argentina—Our  business  is  largely  dependent  upon  economic  conditions  in 

Argentina.” 

During  2018,  Argentina’s  provisional  trade  balance  was  a  deficit  of  approximately  U.S.$  3.8 billion  according  to  preliminary  estimates  from 
INDEC, with total exports of approximately U.S.$ 61.6 billion during 2018, representing a 5.1% increase compared to the same period in 2017. Total 
imports were approximately U.S.$ 65.4 billion, representing a decrease of 2.2% compared to the same period in 2017.

Domestic Oil Prices 

In 2016, a new reduction of approximately 10% in the domestic crude oil price per barrel compared to the price in effect on December 31, 2015 
was agreed upon. This change stemmed from negotiations between producers, refiners and MINEM, whereby it was agreed to reduce the domestic price 
of Medanito crude and Escalante crude since January 2016 until July 2016 to U.S.$67.50 and U.S.$54.90 per barrel, respectively. In addition, in August 
2016 a new agreement between producers, refiners and MINEM provided for a new gradual reduction in the domestic crude oil price per barrel by 2% 
per month in August, September and October for a 6% aggregate drop before November 2016. 

In  2017,  continuing  with  the  gradual  reduction  of  crude  oil  prices  in  the  domestic  market,  an  agreement  among  producers  (the  “Transitional 
Agreement”),  refiners  and  MINEM  was  reached  to  attain  price  parity  with  international  markets  during  the  course  of  2017  and  sustain  domestic 
production and labor sources. This agreement establishes decreasing prices for domestic crude oil during 2017, with the aim of reaching the price of 
Brent crude in the international market as of the effective date of the agreement. As a starting point, a reference price of U.S.$ 59.40 and U.S.$ 48.30 
was set for Medanito and Escalante crude, respectively, for January 2017, with a gradual reduction to U.S.$ 55.00 and U.S.$ 47.00, respectively, in July 
2017 and maintaining those prices until December 2017, provided that the price of Brent crude oil and the exchange rate of the Argentine peso to the 
U.S.  dollar  remains  within  certain  parameters.  It  was  also  agreed  that  imports  of  crude  oil  and  petroleum  products  as  a  complement  to  domestic 
production of these hydrocarbons will be subject to the shortage of both products in the domestic market, for which MINEM will promote the creation 
of  a  registry  of  imports  of  crude  oil  and  derivatives  to  ensure  the  full  utilization  of  domestic  production  within  the  constraints  of  production  and 
processing of each producer and/or refiner. 

The  Transitional  Agreement  provided  that  if,  at  any  time,  the  international  average  price  of  a  barrel  of  Brent  crude  oil  exceeded  the  reference 
value  for  local  crude  oil  of  Medanito  type  by  less  than  one  U.S.  dollar  per  barrel  for  a  period  greater  than  10  consecutive  days,  the  commitments 
assumed by the parties to the agreement would be suspended, effective as of the immediately succeeding calendar month. 

Additionally,  the  Transitional  Agreement  establishes  mechanisms  to  adjust  fuel  prices,  on  a  quarterly  basis,  in  the  domestic  market  in  2017  to 
reflect the impact of changes in crude oil prices, biofuels and changes to the exchange rate, in accordance with the formula established in the agreement. 
In  the  past,  domestic  fuel  prices  had  been  adjusted  but  not  in  line  with  international  market  prices  for  petroleum  products  mainly  due  to  the  market 
conditions affecting the Argentine market. 

On  September 26,  2017,  MINEM  informed  that  the  conditions  for  the  suspension  of  the  Transitional  Agreement  had  been  achieved  on 
September 13,  2017,  and  consequently  the  terms  of  the  Transitional  Agreement  (other  than  the  requirements  relating  to  the  import  of  crude  oil  and 
derivatives)  were  suspended,  effective  as  of  October 1,  2017.  During  November  and  December  of  2017,  the  average  price  of  the  Brent  crude  oil 
continued to run higher than the reference value for local crude oil of Medanito. Consequently, the Transitional Agreement remained suspended and 
finally, as of December 31, 2017, the Transitional Agreement was officially discontinued. 

As a result of the liberalization of the domestic market, our pricing policy for fuels contemplates several factors such as international crude oil 
prices  and,  refining  spreads,  processing  and  distribution  costs,  biofuel  prices,  exchange  rate,  local  demand  and  supply,  competition,  inventories, 
withholding tax on exports, local taxation, and domestic margins for our products, among others. Nevertheless, due to various factors (including, but not 
limited  to, the  abrupt variation in the  exchange rate and the increase in  international prices of  oil and the consequent difficulties to pass-through the 
corresponding  variation  to  domestic  prices)  the  intended  liberalization  could  not  be  fully  realized  during  2018.  Irrespective  of  our  expectation  to 
substantively keep our internal prices referenced to those in the international markets, we cannot assure you that other factors which are also considered 
in  our  price  policy  as  mentioned  above,  will  lead  us  not  to  entirely  reflect  the  import  parity  prices  in  our  domestic  prices,  which  was  evidenced 
throughout 2018. 

Despite  the  price  fixing  mechanisms  described  above,  due  to  the  abrupt  variation  in  the  exchange  rate  and  the  consequent  difficulties  to  pass-
through the corresponding variation to domestic prices, in addition to the increase in international prices of oil, during the second quarter of 2018, the 
MINEM and the refining companies entered into a price stability agreement with a compensatory account, whereby refining companies undertook not to 
make changes in the prices of their products -net of fuel taxes- in force as of the date of the agreement, during the months of May and June. Moreover, 
at  the  beginning  of  June,  a  supplemental  agreement  was  entered  into,  which  established  a  Brent  referent  price  for  oil  purchase  transactions  between 
refining and producing companies, and an increase in the final prices of fuel and gasoil as of June 2, 2018, which included the variation of tax on liquid 
fuels, carbon dioxide tax and the prices of biofuels in force at that date. 

However,  in  view  of  the  volatility  and  significant  change  in  the  variables  which  gave  rise  to  the  price  stability  agreements,  YPF  informed  the 

MINEM of its decision to implement, as of 1 July, 2018, the commercial policies applicable to the changes in the applicable 

149 

variables,  both  for  the  determination  of  its  products’  sale  prices  and  for  the  purchase  of  crude  oil,  in  a  manner  consistent  with  the  evolution  of  the 
business  environment  in  general  and  that  of  customers  in  particular,  in  accordance  with  the  regulatory  framework  and  applicable  regulations. 
Consequently, on June 30, 2018, the price stabilization agreements ceased to be in force for YPF. 

Domestic Gas Prices 

Regarding  the natural  gas market and within  the framework of normalization process of the energy sector, the Ministry of Energy and Mining 
(“MINEM”) convened the natural gas producers (including YPF), the former ENARSA and the distributors to establish basic conditions that serve as 
framework for the supply agreements between them as of January 1, 2018. In the announcement,  MINEM informed that before the ending period of 
extension established in Law No. 27,200 that began in 2002, Law No. 24,076 once again takes full effect, which stipulates that the price of natural gas 
supply agreements will be that determined by free interaction of supply and demand. 

On  November 29,  2017,  the  aforementioned  parties,  at  the  request  of  the  MINEM,  subscribed  the  “Terms  and  Conditions  for  the  Supply  of 
Natural  Gas  to  Gas  Distributors  by  Networks”.  In  them,  the  basic  guidelines  are  established  to:  (i) guarantee  the  adequate  gas  natural  supply  to  the 
distributors, and consequently to the residential and commercial final consumers; (ii) the continuity of the gradual and progressive subsidies reduction 
path, all within the framework of the process of normalization of natural gas market, occurring within the period of validity of said terms and conditions 
until  December 31,  2019;  (iii)  the  recognition  of  the  right  to  transfer  the  cost  of  gas  acquisition  to  the  tariff  payed  by  users  and  consumers;  (iv) gas 
prices  for  each  basin  for  the  next  two  years,  in  U.S.  dollars;  (v) the  ex  ENARSA  assumes  responsibility  to  supply  the  demand  in  areas  reached  by 
subsidies of residential consumption; among others. 

However, as mentioned in the preceding paragraph, and because of the variation in the exchange rate parity, producers and distributors of natural 
gas  began  a  process  of  renegotiation  of  the  specific  agreements  signed  at  the  request  of  the  Terms  and  Conditions,  with  prices  denominated  in  U.S. 
dollars. The renegotiation process includes two main issues: (i) the payment of the debts generated by the differences between the exchange rate paid by 
the  distributors  and  the  contractually  anticipated  exchange  rate  (period  April  -  September  2018)  and  (ii) the  price  of  the  gas  to  apply  for  the  period 
October - April 2019. 

Regarding the account receivables generated by the exchange differences on October 5, 2018, SGE Resolution No. 20/2018 was published, which 
stipulated that, for the differences between the price of gas provided in the contracts and the price of gas recognized in the final tariffs of the service 
providers  of  distribution,  valued  by  the  volume  of  gas  purchased  from  April 1  to  September 30,  2018,  the  ENARGAS  would  instruct  to  the  service 
providers of distribution to the recovery of the credit in favor of producers as a separate line item in the bill of their users, in 24 installments starting on 
January 1, 2019. However, the Resolution No. 20/2018 was subsequently rendered null for reasons of opportunity by Resolution No. 41/2018 published 
on October 12, 2018. Finally, on November 18, 2018, through Decree No. 1053/18, the National State assumed on an exceptional character the payment 
of the daily differences accumulated monthly between the value of the gas purchased by the distributors and the tariffs in force between April 1, 2018 
and March 31, 2019. It is to be paid in 30 consecutive monthly installments, with interest to be paid as of October 1, 2019. 

In addition, the natural gas market for power generation also suffered changes. On August 1, 2018, the MINEM (predecessor to the SGE) issued 
Resolution No. 46/2018 lowering natural gas price reference for electric generation by approximately 20% and instructed Compañía Administradora del 
Mercado Mayorista Eléctrico S.A. (CAMMESA), a government-controlled company, in charge of the electricity dispatch that concentrates the purchase 
of natural gas and fuels for power generation, to acquire combustibles through competitive processes. 

On August 22, 2018, the former Ministry of Energy and Mining issued Resolution No.104/2018, later modified by Resolution No. 9/2018 of the 

SGE, which established a new procedure to obtain authorizations to export natural gas. 

See additionally “Item 4. Information on the Company—Legal and Regulatory Framework and Relationship with the Argentine Government— 

Tariff renegotiation.” 

Energy Demand 

Energy  consumption  in  Argentina  has  increased  significantly  since  2003.  Continued  growth  in  demand  has  led  to  fuel  shortages  and  power 

outages, prompting the Argentine government to take additional measures to assure domestic supply. As a result of this 

150 

increasing  demand,  declines  in  the  production  of  certain  products  and  companies  in  our  industry,  and  actions  taken  by  the  Argentine  regulatory 
authorities to prioritize domestic supply the volumes of hydrocarbon product exports, especially natural gas, have declined steadily during this period. 
At the same time, in recent years, Argentina has increased its imports of natural gas and refined products. 

On December 17, 2015, as a result of Decree No. 134/2015, the new government declared an emergency of the national electricity system until 
December 31, 2017 and instructed the Ministry of Energy and Mining to develop and propose measures that would ensure power supply under adequate 
technical  conditions.  See  “Item  4.  Information  on  the  Company—Legal  and  Regulatory  Framework  and  Relationship  with  the  Argentine 
Government—Market  Regulation—Electricity,”  “Item  3.  Key  Information—Risk  Factors—Risks  Relating  to  Argentina—Our  business  is  largely 
dependent upon economic conditions in Argentina.”

Policy and regulatory developments in Argentina, including the Expropriation Law 

The Argentine oil and gas industry has been subject to certain governmental policies and regulations that have resulted in: (i) domestic prices that 
do not keep pace with those prevailing in international markets (which usually resulted in lower local prices compared to prevailing international market 
prices before the recent decrease in international oil prices); (ii) export and import regulations; (iii) domestic supply requirements that oblige us from 
time to time to divert supplies from the export or industrial markets in order to meet domestic consumer demand; (iv) increasingly higher export duties 
on the volumes of hydrocarbons allowed to be exported, before the recent decrease in international oil prices and before Law No. 26,732 ceased to be in 
force, which established export duties; (v) increasingly higher investment and costs expenditure requirements in order to satisfy domestic demand and 
(vi) increasingly higher taxes, although certain taxes have recently declined as a result of the incentives set by the Argentine government in response to 
the decrease in international oil prices to promote domestic activity. These governmental pricing and tax policies have been implemented in an effort to 
satisfy increasing domestic market demand and, in recent years, to incentivize domestic activity as a result of recent decreases in international oil prices 
allowing domestic prices to stay above those prevailing in international market for certain periods. Since December 2015, the new government has taken 
measures to improve general economic and business conditions in Argentina, such as the elimination of exchange restrictions, the partial adjustment of 
gas  and  electricity  prices  and  the  elimination  or  reduction  of  export  taxes  for  certain  products.  See  “Item  5.  Operating  and  Financial  Review  and 
Prospects—Factors Affecting Our Operations—Macroeconomic conditions.” As discussed in “Item 3. Key Information—Risk Factors” and elsewhere 
in this annual report, actions by the Argentine government have had and will continue to have a significant effect on Argentine companies, including us. 

Notwithstanding  the  foregoing,  after  the  termination  of  the  2017  Transitional  Agreement,  according  to  Argentina’s  Ministry  of  Energy  and 

Mining, the hydrocarbons market in Argentina had become a liberalized market and oil and fuel prices must be set by the 

151 

market conditions and, thus,  fluctuate. As mentioned  before,  this  decision  formally  ended the transition to international oil price parity.  See “Item 5. 
Operating  and  Financial  Review  and  Prospects—Factors  Affecting  Our  Operations—Macroeconomic  conditions.”  and  see  “Item  3.  Key 
Information—Risk Factors—Risks Relating to Our Business—Limitations on local pricing in Argentina may adversely affect our results of operations” 
and “Item 3. Key Information—Risk Factors—Risks Relating to Our Business—We are exposed to the effects of fluctuations in the prices of oil, gas 
and refined products.” 

For information regarding policy and regulatory developments relating to the oil and gas industry in Argentina see “Item 4. Information on the 

Company—Legal and Regulatory Framework and Relationship with the Argentine Government.” 

The  Expropriation  Law  declared  achieving  self-sufficiency  in  the  supply  of  hydrocarbons,  as  well  as  in  the  exploitation,  industrialization, 
transportation  and  sale  of  hydrocarbons,  a  national  public  interest  and  a  priority  for  Argentina.  In  addition,  its  stated  goal  is  to  guarantee  socially 
equitable economic development, the creation of jobs, the increase of the competitiveness of various economic sectors and the equitable and sustainable 
growth of the Argentine provinces and regions. See “Item 4. Information on the Company—Legal and Regulatory Framework and Relationship with the 
Argentine  Government—The  Expropriation  Law.”  Upon  the  passage  of  the  Expropriation  Law,  the  Argentine  government  gained  control  over  the 
Company.  See  “Item  3.  Key  Information—Risk  Factors—  Risks  Relating  to  Argentina—The  Argentine  Republic  owns  51%  of  the  shares  of  the 
Company.” 

Export volumes 

The  exported  volumes of  many  of  our  hydrocarbon  products  have  declined  significantly  in  recent  years,  driven  mainly  by  increasing  domestic 

demand and export administration, as well as by declines in production. 

The table below presents, for the periods indicated, the exported volumes of certain of our principal hydrocarbon products.

Includes bunker oil sales of 228 mtn, 282 mtn and 375 mtn in 2018, 2017 and 2016, respectively. 

Exports accounted for 10.3%, 8.7% and 7.8% of our consolidated revenues in 2018, 2017 and 2016, respectively. Export duties are accounted for 

as tax expenses in our Audited Consolidated Financial Statements. 

The Argentine government currently requires companies intending to export crude oil and diesel to obtain prior authorization from the Argentine 
Ministry of Energy and Mining by demonstrating that local demand for those products has been satisfied. The same criteria is applied to exports of LPG 
upon Law 26,020, dated 2005. 

Seasonality 

Historically, our results have been subject to seasonal fluctuations during the year, particularly as a result of greater natural gas sales during the 
winter. After the 2002 devaluation and as a consequence of the natural gas price freeze imposed by the Argentine government until recent years, the use 
of this fuel has diversified, generating an increase in its long-term demand throughout the year. However, during 2018, mainly due to the increase in the 
natural gas supply in the domestic market, and also taking into account that GDP decline had a negative impact in demand, forced us to reduce natural 
gas output thorough the temporary stop of certain wells gas production, as well as the reinjection of the hydrocarbon. Based on this new scenario and 
new  regulations  (see  “Item  4.  Information  on  the  Company—Legal  and  Regulatory  Framework  and  Relationship  with  the  Argentine 
Government—Natural Gas—Tariffs.”) and agreements, a reduction in natural gas sales prices can be seen in relation to the prices stablished in 2017. 
Based  on  the  detailed,  we  could  be  subject  to  fluctuations  in  non-winter  season  in  our  sales  volumes  and  consequently,  our  level  of  natural  gas 
production could be negatively affected and resulted market prices could be lower than expected. See “Item 3. Key Information—Risk Factors— Risks 
Relating to Our Business—Oil and gas activities are subject to significant economic, environmental, operational risks and seasonal fluctuation.”

Critical Accounting Policies 

Our accounting policies are described in Note 2.a and b. to the Audited Consolidated Financial Statements. IFRS requires us to make estimates 
and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and disclosures of contingent assets and liabilities in 
our  financial  statements.  Actual  results  could  differ  from  those  estimates.  We  consider  the  following  policies  or  matters  to  be  most  critical  in 
understanding the judgments that are involved in preparing our Audited Consolidated Financial Statements and the uncertainties that could impact our 
results of operations, financial condition and cash flows: 

•

•

•

•

•

•

•

•

Functional and reporting currency. See Note 2.b.1 to the Audited Consolidated Financial Statements. 

Impairment of long-lived assets. See Notes 2.b.8 and 2.b.9 to the Audited Consolidated Financial Statements. Furthermore, for additional 
information regarding assumptions used for our impairment calculation as of December 31, 2018, see Note 2.c to the Audited Consolidated 
Financial Statements. 

Impairment of financial assets. See Notes 2.b.2, 2.b.18) and 2.b.26) to the Audited Consolidated Financial Statements. 

Depreciation of oil and gas producing properties. See Note 2.b.6 to the Audited Consolidated Financial Statements. 

Asset retirement obligations. See Notes 2.b.6 and 14.b to the Audited Consolidated Financial Statements. 

Consolidation  decisions  and  classification  of  joint  arrangements.  See  Notes  2.a),  2.b.5),  3  and  9  to  the  Audited  Consolidated  Financial 
Statements. 

Environmental  liabilities,  litigation  and  other  contingencies.  See  Notes  2.c,  14,  27  and  28.b  to  the  Audited  Consolidated  Financial 
Statements. 

Income tax and deferred tax. See Note 15 to the Audited Consolidated Financial Statements. 

In connection with the disclosure of the impact that recently issued accounting standards will have on financial statements in future periods, see 

Note 2.b.26 to the Audited Consolidated Financial Statements as of December 31, 2018. 

In addition, for information regarding our estimates of oil and gas reserves, see “Item 4. Information on the Company—Upstream—Oil and Gas 

reserves.” 

As of December 31, 2018, the Company recognized a reversion of an impairment in the value of its assets to UGE Petroleo of Ps. 39,837 million 
and an impairment of property, plant and equipment mainly to UGE Gas - Cuenca Neuquina of Ps. 28,326 million and UGE Gas – Cuenca Austral of 
Ps. 8,246 million. During 2017, YPF recorded a recovery of Ps. 5,032 million on a prior impairment for property, plant and equipment. As discussed in 
Note  2.c  to  the  Audited  Consolidated  Financial  Statements  as  of  December 31,  2018,  the  recoverable  amount  of  property,  plant  and  equipment  and 
intangible  assets  analysis  is  performed  on  the  year-end  date  or  whenever  there  is  evidence  of  impairment  of  the  recoverable  value.  See  Note  2.c  – 
“Provision for impairment of property, plant and equipment and intangible assets” to the Audited Consolidated Financial Statements. 

It is difficult to predict with reasonable certainty the amount of expected future impairment losses given the many factors impacting the asset base 
and  the  cash  flows  used  in  the  prescribed  ceiling  test  calculation.  These  factors  include,  but  are  not  limited  to,  future  prices,  operating  costs  and 
negotiated savings, foreign exchange rates, capital expenditures timing and negotiated savings, production and its impact on depletion and cost base, 
upward or downward reserve revisions, reserve additions, and tax attributes. According to the foregoing, and in connection with impairment of long-
lived assets according to our estimation as of December 31, 2018, if the average of the oil prices and natural gas prices used for impairment tests as of 
December 31, 2018 were reduced by approximately 10% each year (U.S.$ 5 of the oil prices and U.S.$ 0.50 of the natural gas prices), assuming all other 
factors  remain  constant,  our  ceiling  test  limitation  related  to  the  net  book  value,  of  our  properties,  plant  and  equipment  would  be  reduced  by 
approximately U.S.$ 0.8 billion before tax effects. 

Consequently,  as  noted  above,  actual  cash  flows  may  be  materially  affected  by  other  factors.  There  are  numerous  uncertainties  inherent  in  the 
estimation present value of future cash flow, so this hypothetical calculation should not be construed as indicative of our development plans or future 
results. For more information on recent declines in the international Brent crude oil prices, domestic crude oil prices and domestic gasoline prices, see 
“Item 5. Operating and Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions.” For information regarding 
our domestic oil prices and reserves sensitivity analysis, see “Item 3. Key Information—Risk Factors—Risks Relating to Argentina—Our oil and natural 
gas reserves are estimates.”

Principal Income Statement Line Items 

The following is a brief description of the principal line items of our income statement. 

Revenues 

Revenues  include  primarily  our  consolidated  sales  of  crude  oil  and  natural  gas  and  refined  fuel  and  chemical  products  net  of  the  payment  of 
applicable fuel transfer taxes and turnover taxes. Customs duties on exports are accounted as selling expenses in our consolidated results of operations. 
Royalty  payments  required  to  be  made  to  a  third  party,  whether  payable  in  cash  or  in  kind,  which  are  a  financial  obligation,  or  are  substantially 
equivalent to a production or similar tax, are accounted for as a cost of production and are not deducted from revenues. See “Item 4. Information on the 
Company—Upstream—Oil and gas production, production prices and production costs” and Note 19 to the Audited Consolidated Financial Statements.

Our cost accounted for 82.5%, 83.78% and 84.4% of our consolidated revenues in 2018, 2017 and 2016, respectively. Our cost of sales increased by 
69.8% from 2017 to 2018 due to the factors explained in “-Principal Income Statement Line Items-Cost.” 

Other net operating results 

Other operating results, net principally include provisions for pending lawsuits and other claims, provisions for environmental remediation and 

provisions for defined benefit pension plans and other post-retirement benefits. See “—Other net operating results.” 

Financial income (expense), net 

Financial  income  (expense),  net  consists  of  the  net  of  gains  and  losses  on  interest  paid  and  interest  earned  and  foreign  currency  exchange 

differences. 

Income Tax 

The effective income tax rates for the periods discussed in this annual report differ from the statutory tax rate (30%) mainly because: the registration of 
the deferred income tax as a result of the effect of applying the current tax rate (30%) on the difference generated between the tax basis of fixed and 
intangible  assets  (for  which  any  asset  remeasurement  from  the  original  value  in  pesos  is  not  acceptable  under  income  tax  law)  and  their  book  value 
under IFRS, measured in its functional currency and converted into pesos, as described in Note 2.b.1 to our Audited Consolidated Financial Statements. 
See Note 15 to the Audited Consolidated Financial Statements for a more detailed description of the difference between statutory income tax rate and 
effective  income  tax  rate.  For  information  regarding  the  Law  No. 27,430  and  27,432  introducing  modifications  to  the  Income  Tax,  see  “Item  10. 
Additional Information—Taxation.”

Revenues 

Revenues  in  2018  were  Ps.  435,820 million,  representing  a  72.4%  increase  compared  to  Ps.  252,813 million  in  2017.  Among  the  main  factors 

contributing to the increase were: 

•

•

•

Diesel revenues increased by Ps. 59,097 million in the domestic market, or 73.3%, as a result of an increase in the average price for diesel 
mix  of  approximately  65.9%  and  higher  dispatched  volumes  of  approximately  4.5%.  Additionally,  a  16.5%  increase  in  sales  volumes  of 
Infinia diesel, a premium diesel; 

Gasoline  revenues  increased  by  Ps.  37,863 million,  or  63.9%,  as  a  result  of  an  increase  in  the  average  price  for  gasoline  mix  of 
approximately 58.0% and higher volumes dispatched of approximately 3.7%. Despite the aforementioned, there was a decrease of 7.6% in 
the sales volumes of Nafta Infinia, a premium gasoline; 

Fuel oil revenues in the domestic market decreased by Ps. 3,721 million, or 90.4%, primarily as a result of a decrease in sales volumes of 
94.5% to power generation plants which consumed alternative fuels such as natural gas, partially offset by an increase in the average price 
of approximately 75.7%; 

156 

•

•

•

•

Natural gas revenues in the domestic market increased by Ps. 17,798 million, or 41.8%, as a result of an increase of 50.7% in the average 
sale price in Argentine peso terms, partially offset by a decrease in sales volumes of 6.2%. This reduction is explained by the 4.6% decrease 
in dispatched volumes due to lower production and demand for natural gas in 2018, and in the first quarter of 2017, 242 Mm3 injected and 
pending of nominating were invoiced; 

Natural gas revenues to the retail segment (residential and small business and industries) increased by Ps. 14,515 million, or 140.6%. This 
increase  is  mainly  explained  by  our  affiliated  company  Metrogas  S.A.,  which  as  described  in  Note  2.a  of  the  Consolidated  Audited 
Financial  Statements  as  of  December 31,  2018  (see  “Financial  Information  of  Subsidiaries,  Associates  and  Joint  Ventures  in 
Hyperinflationary Economies”), as it is an Argentine peso functional currency and based on current local regulations, recorded in its sales 
an inflation adjustment of Ps. 4.748 million corresponding to 2018. In addition, this company obtained a higher average price of 122.2%, 
partially offset by a 2.0% decrease in sales volumes through its distribution network; 

The remaining sales in the domestic market increased by Ps. 34,609 million, or 102.2%, primarily due to the increase of sales of LPG by 
90.0%, aerokerosene by 121.4%, petrochemical products by 58.6%, coal by 192.1%, fertilizers by 110.4%, asphalts by 37.0% and lubricants 
by 42.2%, in all of these cases mainly due to the higher prices of these products in Argentine peso terms and higher sales volumes; 

Export  revenues  increased  by  Ps.  22,843 million,  or  103.4%.  Mainly  due  to  the  higher  exports  sales  of  aerokerosene  for  Ps.  8,735,  or 
139.4%,  as  a  result  of  an  increase  in  average  sales  prices  in  Argentine  peso  terms  of  117.9%  and  9.8%  in  sales  volumes,  as  well  as  the 
highest sales volumes and better prices obtained in petrochemical products and LPG, with increases in sales of 4,568 or 156.9% and Ps. 
1,782  or  121.3%,  respectively.  There  were  also  more  export  sales  of  residual  coal  for  Ps.  1,963 million,  and  of  crude  oil  for  Ps. 
1,258 million, in both cases as a result of higher sales volumes. Exports of soy meal and oil had an increase of Ps. 646 million or 10.3%, as 
a result of a 60.6% increase in the prices obtained in Argentine peso terms, partially offset by a decrease in sales volumes of 31.3%. 

Revenues  in  2017  were  Ps.  252,813 million,  representing  a  20.3%  increase  compared  to  Ps.  210,100 million  in  2016.  Among  the  main  factors 

contributing to the increase were: 

•

•

•

•

•

•

•

Diesel revenues increased by Ps. 10,713 million, or 15.1%, as a result of an increase in the average price for diesel mix of 15.9%, partially 
offset by a decrease in sales volumes of 0.7%, despite an 27.5% increase in sales volumes of Infinia diesel, a premium diesel; 

Gasoline revenues increased by Ps. 12,976 million, or 28.1%, primarily as a result of an increase in the average price for gasoline mix of 
19.9%, and an increase in sales volumes of 6.8%, reflecting additionally an increase of 20.0% in sales volumes of Infinia gasoline; 

Fuel  oil  revenues  in  the  Argentine  domestic  market  decreased  by  Ps.  5,531 million,  or  57.3%,  primarily  as  a  result  of  a  decrease  in  the 
average price of 15.5% and a decrease in sales volumes of 49.5%; 

Natural gas revenues  increased by Ps. 6,171 million, or 16.9%,  primarily as a result  of an  increase of  14.1% in the  average sale  price in 
Argentine peso terms, which includes not only higher prices from third parties but also the Gas Plan, which increased the average prices 
obtained  by  YPF  as  a  result  of  increasing  YPF’s  natural  gas  production,  and  also  a  result  of  an  increase  in  sales  volumes  of  1.1%. 
Additionally, in the first quarter of 2017, we invoiced Ps. 603 million corresponding to 242 million m3 opportunely injected and pending 
nomination, which were assigned to the commercial segment of CNG, and resulted in an increase of 2.8% in sales volumes; 

Natural  gas  revenues  to  the  retail  segment  (residential  and  small  general  service  category)  increased  by  Ps.  3,783 million,  or  57.8%, 
primarily  due  to  our  subsidiary  Metrogas  which  registered  an  increase  in  the  average  price  of  approximately  70.1%  partially  offset  by  a 
decrease in sales volumes of 13.1%; 

The  remaining  sales  in  the  domestic  market  increased  by  Ps.  8,875 million,  or  37.1%,  primarily  due  to  the  increase  of  asphalts  sales  by 
154.2%, the increase of LPG sales by 48.9%, petrochemical products by 35.9% and aerokerosene by 37.3%, in all of these cases mainly due 
to the higher prices of these products, with the exception of asphalts, which also registered an increase of 103.5% in sales volumes; 

Export revenues increased by Ps. 5,727 million, or 35.0%, primarily due to increases in exports of petrochemical products of 23.8%, and 
LPG of 57.7%, in both cases due to an increase in average prices in Argentine peso terms, as well as increases in exports of flour and soy 
oils of 24.0%, aerokerosene of 53.9%, and virgin naphtha of 110.3%, all due to an increase in average prices in Argentine peso terms and in 
sales volumes.

Costs 

Costs in 2018 were Ps. 359.570 million, representing a 69.8% increase compared to Ps. 211,812 million in 2017, including increases in production 

costs and purchases of 59.0% and 88.5%, respectively. Among the main factors contributing to this increase were: 

Production costs 

•

•

•

•

•

•

Property, plant and equipment depreciation costs increased by Ps. 32,093 million, or 62.2%, primarily due to the appreciation of the assets 
taking into account their valuation in historical U.S. dollars according to the functional currency of the Company; 

Lifting costs increased by Ps. 19,815 million, or 46.5%, considering an increase of the unit indicator in Argentine peso terms of 52.7%, in 
line with the general increase of prices in the economy, offset by a decrease of the production; 

Refining costs increased by Ps. 2,812 million, or 27.3%. This increase was driven by higher charges for repair and maintenance services, 
consumption of materials, spare parts and other supplies, considering an increase of the unit indicator in Argentine peso terms of 31.5%, 
offset by a decrease of the processed volumes; 

Higher  charges  for  environmental  contingencies  increased  by  Ps.  1,772 million,  or  119.2%,  linked  to  the  activity  developed  by  the 
Downstream and Upstream business areas, fundamentally from the activities of characterization and valorization of environmental actions 
developed during 2018; 

Increments  in  royalties  and  other  charges  associated  with  production  increased  by  Ps.  13,542 million,  or  80.8%,  with  an  increase  of  Ps. 
10,903 million, or 102.9%, in the crude oil production, and an increase of Ps 2,639 million, or 42.8%, in the natural gas production, in both 
cases due to the higher wellhead value of this products, which is established in U.S. dollars measured in Argentine pesos; 

Transportation costs increased by Ps. 3,990 million, or 45.7%, mainly due to increases in rates and higher transported volumes. 

Purchases 

•

•

•

•

•

•

Purchases of crude oil from third parties increased by Ps. 11,463 million, or 57.6%, due to an increase of 97.4% in average prices charged 
by third parties in Argentine peso terms, mainly related to an increase in the international reference price, partially offset by a decrease in 
purchased volumes of approximately 20.2%. However, there has been an increase in purchases of light crude oil compared to heavy crude 
oil; 

Purchases of biofuels (FAME and ethanol biofuel) increased by Ps. 5,910 million, or 32.8%, primarily as a result of an increase in the prices 
of FAME and ethanol biofuel of 46.5% and 19.6%, respectively, and an increase in purchased volumes of ethanol biofuel of 3.6%, partially 
offset by a decrease in purchased volumes of FAME of 3.9%; 

Purchases of natural gas from other producers for resale in the distribution segment to retail customers (residential and small businesses and 
industries) increased by Ps. 8,851 million, or 141.6%, primarily due to our affiliated company Metrogas S.A., which, as described in Note 
2.a of the Consolidated Audited Financial Statements as of December 31, 2018 (see “Financial Information of Subsidiaries, Associates and 
Joint  Ventures  in  Hyperinflationary  Economies”),  as  it  is  an  Argentine  peso  functional  currency  and  based  on  current  local  regulations, 
registered  in  its  purchases  an  adjustment  for  inflation  of  Ps.  1,959 million,  and  additionally  due  to  an  increase  in  the  purchase  price  of 
approximately 122.2%, partially offset by a decrease in purchased volumes of 5.4%; 

Grain purchases in the agricultural sales segment through the form of barter, which were recorded as purchases for accounting purposes, 
increased by Ps. 1,799 million, or 34.0%. This increase is due to an increase in the average price of 58.7%, partially offset by a decrease in 
purchased volumes of 15.6%; 

Imports of fuels increased by Ps. 15,582 million, or 235.0%, as a result of an increase in imports of gasoline Premium for Ps. 1,183 million, 
due  to  the  lower  processing  of  this  product  mainly  (net  of  the  lower  commercialized  volume  of  gasoline  Infinia),  as  well  as  the  higher 
import volumes of gas oil and jet fuel, with increases of Ps. 10,700 million and Ps. 3,699 million, respectively, due to higher international 
prices, higher imported volumes, as well as the devaluation that occurred in the aforementioned period; 

Fertilizers purchases for resale increased by Ps. 2,436 million, or 142.0%, due to an increase in the purchase price of approximately 117.3% 
and an increase in purchased volumes of 11.3%; 

158 

•

In  2018  a  negative  stock  variation  of  Ps.  951 million  was  recorded,  compared  to  the  positive  stock  variation  recorded  in  2017  of  Ps. 
1,556 million, mainly as a result of the decrease in the replacement cost of the Company´s inventories, fundamentally affected by the lower 
amortization from the higher reserves. 

Costs in 2017 were Ps. 211,812 million, representing a 19.5% increase compared to Ps. 177,304 million in 2016, including increases in production 

costs and purchases of 16.0% and 35.5%, respectively. Among the main factors contributing to this increase were: 

•

•

•

•

•

•

•

•

•

•

•

Property, plant and equipment depreciation costs increased by Ps. 8,530 million, or 19.8%, primarily as a result of (i) overall increases in 
Argentine peso terms of the value of fixed assets, which was related to the devaluation of the Argentine peso against the U.S. dollar, which 
is the functional currency of the Company, and (ii) the increase in the depreciation rate due to the decrease in net reserves of crude oil as a 
consequence of a reduction in the selling price in the domestic market, offset by the net decrease in these assets as a result of the impairment 
charge recorded in the third quarter of 2016, which is explained below, and the lower production recorded in 2017; 

Total lifting costs increased by Ps. 5,380 million, or 14.4%, considering an increase of the unit indicator in Argentine peso terms of 19.4%, 
in line with the general increase of prices in the economy, offset by lower production; 

Refining costs increased by Ps. 1,762 million, or 20.6%. This increase was driven by higher charges for consumption of materials, spare 
parts, electricity and other supplies and fuels, considering an increase of the unit indicator in Argentine peso terms of 21.1%; 

Higher charges for environmental contingencies for Ps. 738 million, or 110.9%, linked to the activity developed by the Downstream and 
Upstream business areas; 

Net  increase  in  royalties  and  other  charges  associated  with  production  by  Ps.  319 million,  or  1.9%,  with  an  increase  of  Ps  1,045 million 
related to natural gas production, due to the higher wellhead value of this product, partially offset by a decrease of Ps. 726 million related to 
crude oil production, due to the lower production. 

Transportation costs increased by Ps. 1,772 million, or 25.5%, mainly due to increases in rates in 2017; 

Purchases of crude oil from third parties increased by Ps. 6,259 million, or 45.9%, primarily as a result of an increase in purchased volumes 
of approximately 49.1%, due to lower production, partially offset by a decrease in average prices charged by third parties in Argentine peso 
terms of approximately 2.2%, mainly related to the price agreement between producers and refiners. See “Item 5. Operating and Financial 
Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions”; 

Purchases  of  biofuels  increased  by  Ps.  4,807 million,  or  36.4%,  primarily  as  a  result  of  an  increase  in  the  average  prices  of  FAME  and 
ethanol biofuel of approximately 22.2% and 20.0%, respectively, and an increase in purchased volumes of FAME and ethanol biofuel of 
8.7% and 17.3%, respectively; 

Purchases of natural gas from other producers for resale in the distribution segment to retail customers (residential and small businesses and 
industries)  increased  by  Ps.  1,069 million,  or  20.6%,  primarily  as  a  result  of  an  increase  in  the  purchase  price  of  approximately  22.7%, 
partially offset by a decrease in purchased volumes of 1.7%; 

Grain purchases in the agricultural sales segment through the form of barter, which were recorded as purchases for accounting purposes, 
increased by Ps. 1,141 million, or 27.5%. This increase is due to an increase in the average price of approximately 4.2%, and an increase in 
volumes of 22.3%; and 

Imports of fuels increased by Ps. 1,023 million, or 18.2%, primarily as a result of an increase in purchased Infinia gasoline of 200.1%, jet 
fuel of 21.7%, gas oil of 2.8%. In all cases, purchase prices increased and in terms of imported volumes, there was an increase in Infinia 
gasoline  volumes  and  a  decrease  in  the  other  two  mentioned  products.  Increased  purchases  mentioned  above  were  partially  offset  by  a 
positive  stock  variation  of  Ps.  1,686 million  in  2017,  primarily  due  to  a  recomposition  in  crude  oil  stocks  and  a  revaluation  of  refined 
products,  while in 2016,  this  amount was  negative  for Ps.  1,469 million, primarily due to a  decrease in  crude oil stocks observed in  that 
year. 

Administrative expenses 

Administrative expenses in 2018 were Ps. 13,922 million, representing a 59.4% increase compared to Ps. 8,736 million in 2017, primarily as a 
result  of  increases  in  personnel  costs,  service  contracts  and  IT  licenses,  many  of  which  are  dollarized,  and  due  to  the  higher  charges  related  to 
institutional advertising and depreciation of fixed assets. 

159 

Administrative  expenses  in  2017  were  Ps.  8,736 million,  representing  a  22.6%  increase  compared  to  Ps.  7,126 million  in  2016,  primarily  as  a 

result of increases in personnel costs and IT service contracts, licenses, and institutional advertising. 

Selling expenses 

Selling expenses in 2018 were Ps. 27,927 million, representing a 55.5% increase compared to Ps. 17,954 million in 2017, primarily as a result of 
higher charges for product transportation, mainly related to an increase of the transported volumes, and to an increase in the rates for the transportation 
of fuels in the domestic market, as well as higher charges related to commercial campaigns for customer loyalty, depreciation of fixed assets, personnel 
costs, the provision of doubtful accounts, bank credits and debit and export tax. 

Selling expenses in 2017 were Ps. 17,954 million, representing an 18.0% increase compared to Ps. 15,212 million in 2016, primarily as a result of 
higher charges for product transportation, mainly related to increased transport volumes due to higher sales, and to increased rates for the transportation 
of fuels in the domestic market, as well as increases in personnel costs, charges related to bank credits and debits taxes and export taxes, primarily flours 
and oils, partially offset by a decrease in doubtful accounts in the segment of natural gas distributors and customers of our subsidiary Metrogas. 

Exploration expenses 

Exploration investment in 2018 was 171.6% higher than in 2017. Exploration expenses in 2018 were Ps. 5,466 million, representing a 122.6% 
increase compared to Ps. 2,456 million in 2017, primarily as a result of a Ps. 1,931 million increase in negative results from unproductive exploratory 
drilling in 2018 compared to 2017. Additionally, higher expenses of seismic and geological studies were recorded for Ps. 634 million. 

Exploration  expenses  in  2017  were  Ps.  2,456 million,  representing  a  22.2%  decrease  compared  to  Ps.  3,155 million  in  exploration  expenses  in 

2016, primarily as a result of a Ps. 650 million decrease in negative results from unproductive exploratory drilling in 2017 compared to 2016. 

Recovery / (Impairment) of property, plant and equipment 

In the last quarter of 2018, the Company recognized a net reversal in the charge for impairment of its assets of Ps. 2,900 million, composed mainly 
of the reversal of the provision for impairment assets of the oil CGU of Ps. 39,837 million, mainly due to the increase in reserves and improvements in 
estimated  costs;  partially  offset  by  the  increase  in  the  discount  rate  due  to  the  increase  in  the  country  risk  rate  and  the  debt  cost  and  due  to  higher 
investments associated with the higher reserves considered in the cash flow; partially offset by the impairment of property, plant and equipment for the 
Natural  Gas  CGU—Neuquina  Basin  of  Ps.  28,326 million  and  for  the  Gas  CGU—Austral  Basin  of  Ps.  8,246 million,  mainly  based  on  the  expected 
reduction in the gas market price due to the decrease in the sale price to distributors and power plants (mainly as a result of the offer excess compared to 
domestic  demand  at  certain  times  of  the  year),  and  the  increase  in  the  discount  rate  mentioned  above.  For  a  further  description,  see  “Provisions  for 
impairment of property, plant and equipment” in Note 2.c to the Consolidated Financial Statements as of December 31, 2018. 

In 2017,  the  Company  recorded  a partial  reversal of  the  impairment  for  property, plant  and  equipment  registered  in 2016  of  Ps.  5.032 million, 
mainly due to multiple factors such as the  variation in production and  associated investments considered  in the cash flow: the effect of variations in 
operating and abandonment costs, the variation in the discount rate and, to a lesser extent, the variation in oil prices, also considering the book value of 
the assets as of December 31, 2017 compared to the end of the previous year, based on the depreciation charge versus the increase for new investments 
made,  among  others.  For  a  further  description,  see  additionally  “Item  5.  Operating  and  Financial  Review  and  Prospects—Factors  Affecting  Our 
Operations—Critical Accounting Policies.” and Note 2.c to the Consolidated Financial Statements as of December 31, 2017. 

Other net operating results 

Other  net  operating  results,  in  2018  were  a  gain  of  Ps.  11,945 million,  compared  to  the  loss  of  Ps.  814 million  in  2017.  Mainly,  due  to  the 
recording of the result of the revaluation of YPF’s investment in YPF Energía Eléctrica (“YPF EE”) for Ps. 11,980 million, as a result of the agreement 
for the capitalization of the latter, subscribed between YPF and a subsidiary of GE Financial Services, Inc. as described in Note 3 to the Consolidated 
Audited Financial Statements as of December 31, 2018. 

160 

Other net operating results, in 2017 were a loss of Ps. 814 million, compared to the gain of Ps. 3,394 million in 2016. In 2016, other net operating 
results  mainly  included  a  net  income  of  Ps.1,528 million  attributable  to  the  deconsolidation  of  the  Maxus  Entities  (see  Note  27  to  the  Consolidated 
Financial  Statements  as  of  December 31,  2017)  and  an  income  of  Ps.  1,407 million  related  to  the  PIAM  under  the  concession  agreement  with  the 
Company’s  partner  to  participate  in  the  extension  of  the  concession  of  this  area  and  the  temporary  economic  assistance  accrued  by  our  subsidiary 
Metrogas. 

Operating Profit / (loss) 

Operating profit in 2018 was Ps. 43,780 million due to the factors discussed above representing a 172.4%, compared to the operating profit of Ps. 

16,073 million in 2017. 

Operating profit in 2017 was Ps. 16,073 million due to the factors discussed above, compared to a loss of Ps. 24,246 million in 2016. 

Financial results, net 

In 2018, financial results, net, represented a gain of Ps. 41,525 million, compared to the loss of Ps. 8,798 million in 2017. The Company recorded 
higher positive foreign exchange differences on net monetary liabilities in Argentine pesos of Ps. 45,509 due to the devaluation of the Argentine peso 
against  the  U.S.  dollar  in  2018  compared  to  2017  when  the  devaluation  of  the  local  currency  had  been  substantially  lower.  Additionally,  higher  net 
positive charges were recorded for financial updates for Ps. 10,796 mainly as a result of the increase in the discount rate applied in the abandonment 
provision.  The  aforementioned  was  partially  offset  by  higher  negative  interests  of  Ps.  10,332 million,  as  a  result  of  higher  average  indebtedness, 
measured in Argentine pesos, during 2018 and compared to 2017. 

In 2017, financial results, net, represented a loss of Ps. 8,798 million, representing a 43.2% increase negative results compared to the loss of Ps. 
6,146 million in 2016. The Company recorded lower positive foreign exchange differences on net monetary liabilities in pesos of Ps. 2,661 due to lower 
devaluation of the Argentine peso against the U.S. dollar in 2017 compared to the same period in 2016. The Company recorded higher interest expenses 
of Ps. 276, as a result of higher average indebtedness in 2017 compared to the same period in 2016, almost totally offset by lower interest rates on debt 
in Argentine peso. Additionally, better results were obtained due to an increase of Ps. 382 million from the measurement of the fair value of investments 
in financial assets. 

Income tax 

Income tax in 2018 represented a loss of Ps. 51,538 million, compared to a gain of Ps. 3,969 million in 2017. This increase was mainly due to the 
negative deferred tax charge of Ps. 50,595 million recorded in 2018, mainly as a result of the effects of the exchange rate fluctuations and as mentioned 
previously, in comparison with the positive charge registered in 2017 for Ps. 4,574, due to the effect of the deferred tax liability reduction corresponding 
to the decrease in the tax rate from the approved tax reform in 2017. 

Income tax in 2017 represented a gain of Ps. 3,969 million, representing a 178.5% increase compared to a gain of Ps. 1,425 million in 2016. This 
increase  was  mainly  due  to  the  higher  positive  deferred  tax  charge  of  Ps.  2,415 million.  In  2017,  the  effect  of  the  deferred  tax  liability  reduction 
corresponding to the decrease in the tax rate was recorded from the recently approved tax reform (See “Item 10. Additional Information—Taxation), 
while in 2016 the deferred asset effect was recorded related to the impairment for property, plant and equipment discussed above. 

Net profit / (loss) for the year 

Net profit in 2018 represented a gain of Ps. 38,606 million, compared to a gain of Ps. 12,672 million in 2017. 
Other comprehensive income in 2018 was Ps. 172,600 million, compared to an income of Ps. 21,917 million in 2017. This increase was mainly 

attributable to the higher appreciation of property, plant and equipment. 

161 

As  a  result  of  the  foregoing,  total  comprehensive  income  in  2018  represented  a  gain  of  Ps.  211,206 million,  compared  to  a  gain  of  Ps. 

34,589 million in 2017. 

Net profit / (loss) in 2017 represented a gain of Ps. 12,672 million, compared to a loss of Ps. (28,379) million in 2016. 

Other  comprehensive  income  in  2017  was  Ps.  21,917 million,  representing  a  20.1%  decrease  compared  to  Ps.  27,414 million  in  2016.  This 

decrease was mainly attributable to lower appreciation of property, plant and equipment. 

As a result of the foregoing, total comprehensive income in 2017 represented a gain of Ps. 34,589 million, compared to a loss of Ps. (965) million 

in 2016. 

Consolidated results of operations by business segment for the years ended December 31, 2018, 2017 and 2016 

In  2016,  our  activities  related  to  power  generation  and  natural  gas  distribution  was  separated  from  the  Downstream  activities.  See  “Item  4.

See the table of revenues and operating profit for each of our business segments for the years ended December 31, 2018, 2017 and 2016 in “Item 

4. Information on the Company—Business Organization.” 

Upstream 

During 2018, the Upstream segment had an operating profit of Ps. 22,483 million, compared to an operating profit of Ps. 3,877 million in 2017. 

Crude oil and natural gas sales revenues, net in 2018 were Ps. 210,588 million, representing an 80.5% increase compared to Ps. 116,694 million in 
2017. This increase was principally due to the following factors: 

•

•

Natural gas sales increased by Ps. 18,864 million, or 42.3%, as a result of an increase of 55.7% in the average price in Argentine pesos, 
considering that the average price of natural gas in U.S. dollars registered by the Company during the last quarter of 2018 reached U.S.$ 
4.49 per million BTU, an 8.6% lower compared to U.S.$ 4.92 million BTU during 2017 and considering the devaluation produced between 
both  periods.  Additionally,  the  sales  volumes  showed  a  decrease  of  6.2%,  in  comparison  with  2017  due  to  the  decrease  of  4.6%  in 
dispatched  volumes  as  a  result  of  the  lower  production  and  demand  of  natural  gas  in  2018  and  in  the  first  quarter  of  2017,  242  mmcm 
injected and pending of nominating were invoiced. Also, the total natural gas production corresponding to 2018, reached 42 mmcm/d, which 
represents a decrease of 4.6% compared to 2017 due to lower demand; 

Crude  oil  sales  increased  Ps.  72,001 million,  or  98.2%,  due  to  the  fact  that  the  intersegment  price  of  crude  oil  increased  approximately 
99.5%  measured  in  Argentine  pesos  (an  increase  of  17.5%  in  U.S.  dollars).  Additionally,  the  crude  oil  volume  transferred  between  the 
Upstream  and  the  Downstream  segments  increased  by  0.9%  (approximately  0.12 million  m3),  while  the  sales  volumes  to  third  parties 
increased  by 33.4% (approximately 75  mmcm).  The  crude oil production  during 2018, had  a  slight  decrease of  0.2%  compared  to  2017, 
reaching 227 thousand bbl/d. 

Total  operating  costs  in  2018  were  Ps.  186,426 million  (excluding  exploration  costs),  representing  a  61.6%  increase  compared  to  Ps. 
115,380 million in 2017. Among the main factors contributing to the increase were: 

•

•

•

Property,  plant and  equipment depreciation  costs increased by  Ps.  26,767 million,  or  59.1%,  mainly  due  to the  appreciation  of  the  assets 
taking into account their valuation in historical U.S. dollars according to the functional currency of the Company. 

Lifting costs increased by Ps. 19,815 million, or 46.5%, considering an increase of the unit indicator in Argentine peso terms of 52.7%, in 
line with the general increase of prices in the economy, offset by lower production aforementioned; 

Net  increase  in  royalties  and  other  charges  associated  with  production  by  Ps.  13,542 million,  or  80.8%,  with  an  increase  of  Ps. 
10,903 million, or 102.9%, related to crude oil production, and an increase of Ps 2,639 million, or 42.8%, related to natural gas production, 
in both cases due to the higher wellhead value of this products, which is established in U.S. dollars measured in Argentine pesos;

•

•

Higher charges for environmental contingencies for approximately Ps. 1,291 million, linked to the activity developed in Upstream business 
areas, fundamentally from the activities of characterization and valorization of environmental actions developed during 2018; 

In  2018  a  negative  stock  variation  of  Ps.  1,932 million  was  recorded,  compared  to  the  positive  stock  variation  recorded  in  2017  of  Ps. 
113 million,  mainly  as  a  result  of  the  lower  depreciation,  which  is  a  component  part  of  the  valuation  of  the  products,  based  on  higher 
reserves. 

Exploration expenses in 2018 were Ps. 5,466 million, representing a 122.6% increase compared to Ps. 2,456 million in 2017, primarily as a result 
of a Ps. 1,931 million increase in negative results from unproductive exploratory drilling in 2018 compared to 2017. Additionally, higher expenses of 
seismic and geological studies were recorded for Ps. 634 million. 

In the last quarter of 2018, the Company recognized a net reversal in the charge for impairment of its assets of Ps. 2,900 million, composed mainly 
of  reversal of the provision for impairment assets  of the  oil CGU of  Ps. 39,837 million,  mainly due to the increase  in  reserves and improvements  in 
estimated  costs;  partially  offset  by  the  increase  in  the  discount  rate  due  to  the  increase  in  the  country  risk  rate  and  the  debt  cost  and  due  to  higher 
investments associated with the higher reserves considered in the cash flow; partially offset by the impairment of property, plant and equipment for the 
Natural Gas CGU—Neuquina Basin of Ps. 28,326 million and for the Gas CFGU—Austral Basin of Ps. 8,246 million, mainly based on the expected 
reduction in the gas market price due to the decrease in the sale price to distributors and power plants (mainly as a result of the offer excess compared to 
domestic  demand  at  certain  times  of  the  year),  and  the  increase  in  the  discount  rate  mentioned  above.  For  a  further  description,  see  “Provisions  for 
impairment of property, plant and equipment and intangible assets” in Note 2.c to the Consolidated Financial Statements as of December 31, 2018. 

In the last quarter of 2017, the Company recorded a partial reversal of the impairment for property, plant and equipment mentioned above of Ps. 
5,032 million, mainly due to multiple factors such as the variation in production and its associated investments considered in the cash flow, the effect of 
variations in operating and abandonment costs, the variation in the discount rate and, to a lesser extent, the variation in oil prices, also considering the 
book value of the assets as of December 31, 2017 compared to the end of the previous year, based on the depreciation charge versus the increase for new 
investments made, among others. 

Additionally,  in  2018  the  operating  profit  of  this  business  segment  included  a  gain  of  Ps.  2,322 million  related  to  the  transfer  of  participation, 

mainly, in the areas of Aguada Pichana, Aguada de Castro, Bajo del Toro and Cerro Bandera. 

Operating profit in 2017 for the Upstream business segment represented a gain of Ps. 3,877 million, compared to a loss of Ps. 26,845 million in 

2016. 

Revenues from the Upstream business segment in 2017 were Ps. 116,694 million, representing a 2.2% increase compared to Ps. 114,143 million 

in 2016. 

This increase in operating income was principally due to the following factors: 

•

•

The intersegment oil price measured in U.S. dollars decreased 8.2%, while increasing 3.0% in Argentine peso terms. Oil production in 2017 
reached 227,500 barrels per day, representing a 7.0% decrease compared to 2016. The natural decline of the mature fields, together with the 
effects of the heavy rain and snow storms during the second quarter of 2017, that affected mainly the province of Chubut, and to a lesser 
extent  the  province  of  Santa  Cruz,  are  the  reasons  leading  to  this  decrease  in  crude  production.  This  contributed  to  the  decrease  of 
1.05 mmcm of crude oil, or 7.5%, transferred from the Upstream business segment to the Downstream business segment and a decrease of 
approximately 204 mcm of crude oil, or 47.6%, in sales to third parties; and 

Natural  gas  production  in  respect  of  our  operations  in  Argentina  in  2017  reached  44.1 mmcm  per  day,  representing  a  1.1%  decrease 
compared to 2016. In the fourth quarter of 2016, certain volumes of natural gas were injected that were pending of nomination and were 
only billed in the first quarter of 2017. Sales volumes increased 1.1% in 2017 compared to 2016. The Upstream business segment records 
the average price obtained by YPF in such sales, net of sales and marketing fees. The Upstream segment also includes revenues from the 
Gas Plan, which increases the average prices obtained by YPF as a result of increasing YPF’s natural gas production. The average natural 
gas revenue recorded by the Company in 2017, including revenues from the Gas Plan, was U.S.$ 4.92 per million BTU, a 3.7% increase 
compared to U.S.$ 4.74 per million BTU in 2016.

Total operating costs in respect of our operations in Argentina in 2017 were Ps. 115,380 million (excluding exploration costs), representing 
a 11.0% increase compared to Ps. 103,965 million in 2016. Among the main factors contributing to the increase were: 

Property,  plant  and  equipment  depreciation  costs  increased  by  Ps.  7,188 million,  or  18.9%,  primarily  as  a  result  of overall  increases  in 
Argentine peso terms of the value of fixed assets, which was related to the devaluation of the Argentine peso against the U.S. dollar, which 
is the functional currency of the Company, compensated by the net decrease of assets as a result of the impairment charge recorded in 2016, 
described above and by the lower production recorded in the year; 

Total lifting costs increased by Ps. 5,380 million, or 14.4%, considering an increase of the unit indicator in Argentine peso terms of 19.4%, 
in line with the general increase of prices in the economy, offset by lower production; 

Net  increase  in  royalties  and  other  charges  associated  with  production  by  Ps.  319 million,  or  1.9%,  with  an  increase  of  Ps  1,045 million 
related to natural gas production, due to the higher wellhead value of this product, partially offset by a decrease of Ps. 726 million related to 
crude oil production, due to the lower production; 

Decrease in provisions for stand-by equipment by Ps. 523 million, or 14%, and: 

In 2017, a positive stock variation was recorded for Ps.195, compared to a negative stock variation recorded in 2016 for Ps. 1,330 million, 
due to a reduction in the volumes in stock in 2016. 

Exploration expenses  in 2017 were Ps.  2,456 million,  representing  a 22.2% decrease  compared  to  Ps. 3,155 million in exploration expenses in 2016, 
primarily as a result of a Ps. 650 million decrease in negative results from unproductive exploratory drilling in 2017 compared to 2016. 

In 2016, the Company recorded an impairment for property, plant and equipment of Ps. 34,943 million, mainly due to an estimated reduction in 
the  price  of  oil  marketed  in  the  domestic  market,  together  with  the  estimated  evolution  of  costs  based  on  both  macroeconomic  variables  and  the 
operational  behavior  of  the  Company’s  assets.  For  a  more  detailed  description,  see  Note  2.c  to  the  Consolidated  Financial  Statements  as  of 
December 31, 2016. 

In 2017, the Company recognized a partial reversal of the impairment charge mentioned in the previous paragraph for Ps. 5,032 million, which is 
generated by the combination of multiple factors, such as the variation in production and associated investments considered in the flow, the effect of 
variations in operating and abandonment costs, the variation in the rate of discount and, to a lesser extent, the variation in oil prices, taking into account 
also  the  book  value  of  the  assets  as  of  December 31,  2017  compared  to  the  previous  year,  based  on  the  accounting  depreciation  charge  versus  the 
increase  for  new  investments  made,  among  others.  See additionally  “Item  5.  Operating  and  Financial  Review  and  Prospects—Factors  Affecting  Our 
Operations—Critical Accounting Policies.” and Note 2.c to the Consolidated Financial Statements as of December 31, 2017. 

In 2016, other net operating profit included income of Ps. 1,407 million related to the PIAM under the concession agreement with the Company’s 

partner to participate in the extension of the concession of this area. 

Downstream 

Revenues  from  the  Downstream  segment  in  2018  were  Ps.  339,730 million,  representing  a  73.1%  increase  compared  to  Ps.  196,309 million  in 

2017. 

Operating  profit  for  the  Downstream  business  segment  in  2018  was  Ps.  7,818 million,  representing  a  50.6%  decrease  compared  to  Ps. 

15,813 million in 2017. Among the different aspects, favorable and unfavorable, that affected the operating profit, the following stand out: 

•

In 2018, the processing levels of the refineries reached 88.8%, 3.2% lower than 2017, mainly as a result of the lower demand for Fuel oil 
due to higher availability of natural gas in the system. With these levels of processing a higher production of Diesel (+0.6%) and Gasoline 
(+2.1%) was obtained (the latter corresponding to the higher production of Super gasoline (+10.9%) partly offset by lower production of 
Infinia gasoline (-14.8%). Additionally, the production of other refined products such as liquefied petroleum gas (LPG) and petroleum coal 
increased; and production of Fuel Oil, asphalts, lubricant bases and petrochemical gasoline decreased, all compared to 2017 production;

Diesel revenues increased by Ps. 59,097 million, or 73.3%, as a result of an increase in the average price for diesel mix of 65.9%, and of an 
increase in dispatched volumes of 4.5%. Additionally, sales volumes of Infinia diesel, a premium diesel, increased by 16.5%; 

Gasoline revenues increased by Ps. 37,863 million, or 63.9%, as a result of an increase in the average price for gasoline mix of 58.0%, and 
of an increase in dispatched volumes of 3.7%. Despite the aforementioned, the Infinia gasoline reflecting additionally a decrease of 7.6% in 
sales volumes of Infinia gasoline; 

Fuel oil revenues in the domestic market decreased by Ps. 3,721 million, or 90.4%, as a result of a decrease in the commercialized volumes 
of 94.5% to the power generation plants which consumed alternative fuels as natural gas, partially offset by an increase in the average price 
of approximately 75.7%; 

The remaining sales in the domestic market increased by Ps. 27,338 million, or 90.3%, primarily as a result of increased sales of Asphalts 
by 37.0%, of LPG by 90.0%, petrochemical products by 58.6% and aerokerosene by 121.4%, in all these cases mainly due to the higher 
prices of these products in Argentine peso terms; 

Export revenues obtained by the Downstream segment increased by Ps. 22,843 million, or 103.4%, primarily due to increases in exports of 
aerokerosene of 139.4%, as a result of an increase in the average price of 117.9% measured in Argentine pesos and of an increase of 9.8% in 
the sales volumes. As well as, the higher sales volumes and better prices obtained in petrochemicals products and LPG, with increases in 
sales of 156.9% and 121.3%, respectively. There were also more export sales of residual coal for Ps. 1,963 million, and of crude oil for Ps. 
1,258 million,  in  both  cases  due  to  higher  sales  volumes.  Exports  of  soy  meal  and  oil  had  an  increase  of  Ps.  646 million,  or  10.3%,  in 
comparison with 2017, motivated by a 60.6% increase in the prices obtained, partially offset by a decrease in sales volumes of 31.3%. 

The operating costs in 2018 were Ps. 305,234 million, 88.1% higher compared to the Ps. 162,309 million corresponding to 2017. Among other 

aspects, the following stand out: 

•

•

•

•

•

•

Purchases  of  crude  oil  increased  by  Ps.  84,310 million,  or  91.4%.  The  purchased  volume  from  third  parties  decreased  by  20.2% 
(approximately  708  Mm3),  while  the  crude  oil  volume  transferred  from  the  Upstream  segment  increased  by  0.9%  (approximately  0.12 
Mm3). Additionally, an increase of 98.5% in average prices of crude oil in Argentine peso terms, mainly related to the occurred devaluation 
and to an increase in the international reference price; 

Purchases of biofuels (FAME and ethanol biofuel) increased by Ps. 5,910 million, or 32.8%, primarily as a result of an increase in the prices 
of FAME and ethanol biofuel of 46.5% and 19.6%, respectively, and an increase in purchased volumes of ethanol biofuel of 3.6%, partially 
offset by a decrease in purchased volumes of FAME of 3.9%; 

Imports of fuels increased by Ps. 15,582 million, or 235.0%, as a result of an increase in imports of gasoline Premium for Ps. 1,183 million, 
due  to  the  lower  processing  of  this  product  mainly  (net  of  the  lower  commercialized  volume  of  gasoline  Infinia),  as  well  as  the  higher 
import volumes of gas oil and jet fuel, with increases of Ps. 10,700 million and Ps. 3,699 million, respectively, due to higher international 
prices, higher imported volumes, as well as the devaluation that occurred in the aforementioned period; 

Grain purchases in the agricultural sales segment through the form of barter, which were recorded as purchases for accounting purposes, 
increased by Ps. 1,799 million, or 34.0%. This increase is due to an increase in the average price of 58.7%, partially offset by a decrease in 
purchased volumes of 15.6%; 

In  2018  a  negative  stock  variation  of  Ps.  1,808 million  was  recorded,  compared  to  the  positive  stock  variation  recorded  in  2017  of  Ps. 
3,693 million, mainly as a result of a lower valuation of the stocks in comparison with 2017, due to a decrease in the crude oil price towards 
the end of 2018 (transfer price valuation); 

Refining costs increased by Ps. 2,812 million, or 27.3%. This increase was driven by higher charges for repair and maintenance services, 
consumption of materials, spare parts and other supplies, considering an increase of the unit indicator in Argentine peso terms of 31.5%, 
offset by a decrease of the processed volumes afore mentioned;

Higher charges for environmental contingencies for Ps. 480 million, or 56.0%, linked to the activity developed by the Downstream business 
areas, fundamentally from the activities of characterization and valorization of environmental actions developed during 2018; 

Property, plant and equipment depreciation increased by Ps. 4,383 million, or 75.7%, primarily as a result of (i) increased investments in 
property,  plant  and  equipment  and  (ii) overall  increases  in  Argentine  peso  terms  of  the  value  of  fixed  assets,  which  was  related  to  the 
devaluation of the Argentine peso against the U.S. dollar, which is the functional currency of the Company; 

Fertilizers purchases for resale increased by Ps. 2,436 million, or 142.0%, due to an increase in the purchase price of approximately 117.3% 
and an increase in purchased volumes of 11.3%; 

Transportation  costs  (naval  and  pipelines)  increased  by  Ps.  1,977 million,  mainly  due  to  an  increase  of  38.6%  in  the  rates  in  Argentine 
pesos; 

Selling expenses increased by Ps. 8,934 million, or 51.8%, primarily as a result of an increase in transport expenses, mainly related to an increase 
in  transported  volumes,  due  to  higher  sales,  and  of  an  increase  in  the  transportation  rates  of  fuels  in  the  domestic  market,  as  well  as  increases  in 
personnel costs, charges related to bank credits and debits tax and export tax, primarily meals and oils; 

Revenues  from  the  Downstream  segment  in  2017  were  Ps.  196,309 million,  representing  a  20.1%  increase  compared  to  Ps.  163,463 million  in 

2016. 

Operating  profit  for  the  Downstream  business  segment  in  2017  was  Ps.  15,813 million,  representing  a  411.3%  increase  compared  to  Ps. 

3,093 million in 2016. This increase in operating profit is primarily due to the following factors: 

•

•

•

•

•

•

•

•

The average volume of oil processed per day in YPF’s refineries was about 293,000 barrels of oil per day, without significant changes with 
respect to 2016. With these similar processing levels we obtained a similar production overall, with an increase of diesel by 0.5%, gasoline 
by  2.0%  and  a  decrease  of  fuel  oil  by  35,8%  and  with  increased  production  of  jet  fuel,  petrochemical  gasoline,  asphalts,  coal  oil  and 
lubricant bases; 

Diesel revenues increased by Ps. 10,713 million, or 15.1%, as a result of an increase in the average price for diesel mix of 15.9%, partially 
offset by a decrease in sales volumes of 0.7%, despite an 27.5% increase in sales volumes of Infinia diesel, a premium diesel; 

Gasoline revenues increased by Ps. 12,976 million, or 28.1%, primarily as a result of an increase in the average price for gasoline mix of 
19.9%, and an increase in sales volumes of 6.8%, reflecting additionally an increase of 20.0% in sales volumes of Infinia gasoline; 

Fuel  oil  revenues  in  the  Argentine  domestic  market  decreased  by  Ps.  5,531 million,  or  57.3%,  primarily  as  a  result  of  a  decrease  in  the 
average price of 15.5%and a decrease in sales volumes of 49.5%; 

The remaining sales in the domestic market increased by Ps. 8,848 million, or 43.4%, primarily as a result of increased sales of Asphalts by 
154.2%, of LPG by 48.9%, petrochemical products by 35.9% and aerokerosene by 37.3%, in all these cases mainly due to the higher prices 
of these products, with the exception of asphalts, which also registered an increase of 103.5% in sales volumes; 

Export revenues obtained by the Downstream segment increased by Ps. 5,840 million, or 36.0%, primarily due to increases in exports of 
petrochemical products of 23.8%, and LPG of 57.7%, in both cases due to an increase in average prices in Argentine peso terms, as well as 
increases in exports of flour and soy oils of 24.0%, aerokerosene of 53.9%, and virgin naphtha of 110.3%, all due to an increase in average 
prices in Argentine peso terms and in sales volumes.

Purchases of crude oil increased by Ps. 2,688 million, or 3.0%, primarily as a result of an increase in oil prices of approximately 2.3% in 
Argentine peso terms as a result of the devaluation of the Argentine peso against the U.S. dollar. Crude oil transferred volumes from the 
Upstream  business  segment  decreased  by  7.5%  (approximately  1.05  mmcm),  while  crude  oil  purchased  volumes  from  third  parties 
increased approximately 49.1% (approximately 1.16 mmcm); 

Purchases  of  biofuels  increased  by  Ps.  4,807 million,  or  36.4%,  primarily  as  a  result  of  an  increase  in  the  average  prices  of  FAME  and 
ethanol biofuel of approximately 22.2% and 20.0%, respectively, and an increase in purchased volumes of FAME and ethanol biofuel of 
8.7% and 17.3%, respectively;

Imports of fuels increased by Ps. 1,023 million, or 18.2%, primarily as a result of an increase in import prices of gas oil of 34.3% and jet 
fuel of 35.0%, and of an increase in volumes of 83.7% and purchase prices of 63.4% of Premium gasoline. All of this was partially offset by 
a decrease in imported volumes of gas oil of 23.5% and in imported volumes of jet fuel of 9.8%. 

Grain purchases in the agricultural sales segment through the form of barter, which were recorded as purchases for accounting purposes, 
increased by Ps. 1,141 million, or 27.5%. This increase was due to an increase in the average price of approximately 4.2%, and an increase 
in volumes of 22.3%. 

In 2017, a positive stock variation was recorded by Ps. 3.667, representing an increase of Ps. 3,173 million compared to 2016, mainly as a 
result  of  a  higher  valuation  of  the  stocks,  and  to  a  lesser  extent,  by  an  accumulation  of  stock,  especially  of  crude  oil,  due  to  the  higher 
purchases made in the year 2017; 

Higher  charges  for  environmental  contingencies  of  approximately  Ps.  594 million,  or  328.9%,  linked  to  the  activity  developed  by  the 
Downstream business segment; 

Property, plant and equipment depreciation increased by Ps. 1,247 million, or 27.4%, primarily as a result of (i) increased investments in 
assets (in particular, the launch of the new Coke unit at the La Plata refinery in the fourth quarter of 2016) and (ii) an overall increase in 
property, plant and equipment values in Argentine pesos, which was related to the devaluation of the Argentine peso against the U.S. dollar, 
which is the functional currency of the Company; 

Selling  expenses  increased  by  Ps.  2,707 million,  or  18.6%,  primarily  as  a  result  of  increases  in  transport  expenses,  mainly  related  to 
increased  transport  volumes,  due  to higher  sales, and  to  increased  rates  for  the  transportation  of fuels  in  the  domestic market,  as  well  as 
increases in personnel costs, charges related to bank credits and debits taxes and export taxes, primarily flours and oils; 

Production  costs  related  to  refining  costs  increased  by  Ps.  1,762 million,  or  20.6%.  This  increase  was  driven  by  higher  charges  for 
consumption  of  materials,  spare  parts,  electricity  and  other  supplies  and  fuels.  As  a  result  of  this,  and  considering  that  the  level  of 
processing in refineries was 0.2% lower, the cost of unit refining increased by 21.1% in 2017 compared to 2016. In turn, transportation costs 
related to production (naval and pipelines) increased by Ps. 985 million, or 23.8%. 

In the other net operating results for this segment, we recorded an increase in the provision for lawsuits and contingencies of approximately 
Ps. 528 million compared to the previous year. 

Gas and Power 

In  2016,  the  Company  began  to  report  separately  its  Gas  and  Power  business  segment,  as  explained  in  “Item  4.  Information  on  the 
Company—Business  Organization,”  which  includes  the  transportation,  distribution  and  commercialization  of  natural  gas  to  third  parties,  natural  gas 
liquid (NGL), regasification services and electricity generation. 

Revenues  from  the  Gas  and  Power  segment  in  2018  were  Ps.  99,038 million,  which  represents  an  increase  of  62.7%  compared  to  the  Ps. 

60,880 million in 2017. Among the different aspects that affected this segment the following stand out: 

• As producers, sales of natural gas in the domestic market increased by Ps 17,798 million, or 41.8%, as a result of an increase in the average price 
of  50.7%  in  Argentine  pesos,  partially  offset  by  a  reduction  of  6.2%  in  the  sales  volume.  This  reduction  is  explained  by  the  4.6%  decrease  in 
shipped volumes as a result of lower production and demand for natural gas in 2018, and in the first quarter of 2017, 242 mmcm injected and 
pending of nominating were invoiced; 

• Sales  of  natural  gas  to  the  retail  segment  (residential  and  small  businesses  and  industries)  increased  by  Ps.  14,515 million,  or  140.6%.  This 
increase  is  mainly  explained  by  our  affiliated  company  Metrogas  S.A.,  which,  as  described  in  Note  2.a  of  the  Consolidated  Audited  Financial 
Statements as of December 31, 2018 (see “Financial information of subsidiaries, associates and joint ventures in hyperinflationary economies”), as 
it  is  an  Argentine  peso  functional  currency  and  based  on  current  local  regulations,  registered  in  its  revenues  an  adjustment  for  inflation  of  Ps. 
4,748 million in 2018. Additionally, obtained a higher average price of 122.2%, partially offset by a 2.0% decrease in sales volumes through its 
distribution network. 

Operating profit in 2018 was Ps. 16,786 million, representing an increase of 415.1% compared to Ps. 3,259 million of operating profit in 2017. 
This increase is mainly due to the fact that in the first quarter of 2018, a result was recorded from the revaluation of YPF’s investment in YPF Energía 
Eléctrica (YPF EE) for Ps. 11,980 million. 

167 

Revenues  from  the  Gas  and  Power  business  segment  in  2017  were  Ps.  60,880 million,  representing  a  108.0%  increase  compared  to  Ps. 
29,276 million in 2016, mainly due to the fact that the Stimulus Plan for Surplus Natural Gas Injection in this business segment began to be accrued in 
2017. 

The  operating  profit  for  the  Gas  and  Power  business  segment  in  2017  represented  a  gain  of  Ps.  3,259 million,  representing  a  62.3%  increase 
compared to a gain of Ps. 2,008 million in 2016. This increase was mainly due to the gradual recomposition of rates obtained by our subsidiary company 
Metrogas S.A.,  which recorded an operating  income  of Ps. 1,427 million in  2017, compared to an  operating profit of Ps. 310 million in 2016. There 
were also better operating results from our subsidiary company YPF EE attributable to this segment. 

Central Administration and Others 

The operating  loss of Central  Administration and Others in 2018 was Ps, 6,055 million, compared to the operating loss of Ps. 4,400 million in 
2017, which represents an increase of 37.6%. The variation is mainly related to increases in personnel costs, services contracts and IT licenses, many of 
which are dollarized, and due to the higher charges related to institutional advertising and depreciation of fixed assets. 

The operating loss for the Central Administration and Others in 2017 represented a loss of Ps. 4,400 million, representing a 172.4% increase in 
loss compared to a loss of Ps. 1,615 million in 2016. In the second quarter of 2016, this segment included a net profit of Ps.1,528 million attributable to 
the deconsolidation of the Maxus Entities (see Note 27 to the Audited Consolidated Financial Statements). The remaining variation is mainly related to 
increases in personnel costs, higher charges for computer licenses and lower results obtained by our subsidiary A-Evangelista SA, resulting in part from 
the lower incentives for construction by Ps. 234 million. 

Liquidity and Capital Resources 

Financial condition 

Total  loans  outstanding  as  of  December 31,  2018,  2017  and  2016  were  Ps.  335,078 million,  Ps.  191,063 million  and  Ps.  154,345 million, 
respectively,  consisting  of  (i) current  loans  (including  the  current  portion  of  non-current  loans)  of  Ps.  64,826 million  and  non-current  loans  of  Ps. 
270,252 million as of December 31, 2018, (ii) current loans of Ps. 39,336 million (including the current portion of non-current loans) and non-current

and non-current loans of Ps. 127,568 million as of December 31, 2016. As of December 31, 2018, 2017 and 2016, 86%, 77%, and 70% of our loans 
were denominated in U.S. dollars, respectively. 

In the past we have repurchased certain of our publicly-traded bonds in open market transactions on an arms-length basis. As of December 31, 
2018,  we  had  repurchased  Ps.  410 million  of  our  outstanding  bonds.  We  may,  from  time  to  time,  make  additional  purchases  of,  or  effect  other 
transactions relating to, our publicly-traded bonds if, in our own judgment, the market conditions are attractive.

Net  cash  flows  from  operating  activities  were  Ps.  125,058 million  in  2018  compared  to  Ps.  71,974 million  in  2017.  This  73.8%  increase  was 
primarily attributable to better operating results, without considering impairment of property, plant and equipment and intangible assets, depreciation of 
property, plant and equipment and amortization of intangible assets, increased non-cash provisions,

which did not involve expenditures, and without considering the revaluation result of the aforementioned investment in YPF EE. We believe that, given 
the  high  level  of  cash  flow  provided  by  operating  activities,  including  our  expectation  of  reducing  accounts  receivable  from  transactions  with 
government entities (see “Item 3. Key Information—Risk Factors—Risks Relating to Our Business—A significant percentage of our cash flow from 
operations is derived from counterparties that are governmental entities”) and certain private clients, our working capital is reasonable for the current 
requirements of the Company. 

Net  cash  flows  from  operating  activities  were  Ps.  71,974 million  in  2017  compared  to  Ps.  49,183 million  in  2016.  This  46.3%  increase  was 
primarily attributable to better operating results, without considering impairment of property, plant and equipment and intangible assets, depreciation of 
property,  plant  and  equipment  and  amortization  of  intangible  assets,  increased  non-cash  provisions,  which  did  not  involve  expenditures,  and  lower 
income tax. On the other hand, there was a decrease in net working capital, mainly due to the higher accounts payable as a result of higher purchases 
and  higher  collections  from  the  natural  gas  distribution  companies.  In  addition,  in  2016,  we  received  pending  payments  under  the  Gas  Plan  until 
December 31, 2015, through the delivery of public debt instruments, specifically BONAR 2020 USD (see “Item 4. Information on the Company—Legal 
and Regulatory Framework and Relationship with the Argentine Government—Market Regulation—Natural gas”). The bonds were in portfolios as of 
December 31, 2016 and did not increase the operating cash of the Company. 

Cash flows used in investing activities were Ps. 82,251 million in 2018, compared to Ps. 55,242 million in 2017, representing a 48.9% increase 
compared  with  2017,  as  a  result  of  an  increase  in  investments  of  property,  plant  and  equipment  and  intangible  assets  in  pesos  mainly  due  to  the 
devaluation of the Argentine peso against the U.S. dollar, which is the functional currency of the Company, and a greater liquidation of investments in 
financial assets, which came mainly from the collection of the Gas Plan through the receipt of public securities mentioned in the previous paragraph. 

Cash flows used in investing activities were Ps. 55,242 million in 2017, compared to Ps. 66,174 million in 2016, representing a 16.5% decrease 
compared with 2016, as a result of a reduction in investments of property, plant and equipment and intangible assets in order to align said investments to 
the  operational  generation  of  funds,  a  greater  liquidation  of  investments  in  financial  assets,  which  came  mainly  from  the  collection  of  the  Gas  Plan 
through the receipt of public securities mentioned in the previous paragraph, and a decrease in financial loans granted. 

Net cash flows provided by financing activities in 2018 were Ps. (43,656) million, which came primarily from lower takeover, net cancellation of 
debt maturity and higher interest payment. In 2018, at the shareholders’ ordinary and extraordinary general meeting held on April 27, 2018, a dividend 
of Ps. 1,200 million (Ps. 3.05 per share or ADS) was authorized and paid in December 2018. 

Net cash flows provided by financing activities in 2017 were Ps. (355) million, which came primarily from lower takeover, net cancellation of 
debt maturity and higher interest payment. In 2017, at the shareholders’ ordinary and extraordinary general meeting held on April 28, 2017, a dividend 
of  Ps. 716 million (Ps. 1.82 per share or ADS)  was authorized and paid in December 2017. In 2016, at the shareholders’ ordinary and extraordinary 
general meeting held on April 29, 2016, a dividend of Ps. 889 million (Ps. 2.26 per share or ADS) was authorized for payment in 2016. 

A Global Medium-Term Notes Program was approved at a shareholders’ meeting held on January 8, 2008 for an amount up to U.S.$1.0 billion. 
On September 13, 2012 and on April 30, 2013, the shareholders’ meeting approved the increase of the amount of the program, mentioned above, for an 
amount of U.S.$ 2.0 billion each time, resulting in a maximum nominal amount in circulation at any time under the program of U.S.$ 5.0 billion, or its 
equivalent  in  other  currencies,  and  providing  the  use  of  the  proceeds  to  cover  all  alternatives  contemplated  by  Article  36  of  Law  No. 23,576  of 
Negotiable  Obligations  and  Supplementary  rules.  On  February 5,  2015,  the  shareholders’  meeting  resolved  by  a  majority  of  computable  votes  to 
approve the increase of the amount of the Company’s Global Medium-Term Notes Program of U.S.$ 5.0 billion or its equivalent in other currencies by 
U.S.$  3.0 billion,  resulting  in  the  total  maximum  nominal  amount  outstanding  under  the  program  at  any  time  becoming  U.S.$  8.0 billion,  or  its 
equivalent in other currencies, or a lower amount as may be determined by the Board of Directors. 

On  April 29,  2016,  the  Ordinary  and  Extraordinary  General  Meeting  of  Shareholders  approved  the  increase  of  the  amount  of  the  Company’s 
Global Medium Term Note Program (Programa Global de Emisión de Títulos de Deuda de Mediano Plazo de la Compañía) by U.S.$2.0 billion, to a 
total of U.S.$10.0 billion, or its equivalent in other currencies to remain outstanding at any time under the program. In addition, the term of the Program 
was extended for five years starting from October 25, 2017 by our shareholders at a meeting held on April 28, 2017 and in a meeting of our Board of 
Directors held on June 7, 2017. 

On December 28, 2018, by means of Resolution No. RESFC-2018-19961-APN-DIR # CNV, we were registered as “frequent issuer No. 4” under 
the  simplified  regime  for  frequent  capital  markets’  issuers  (régimen  simplificado  para  emisores  frecuentes)  created  by  the  CNV  on  June  2018.  This 
regime  seeks  to  speed  up  internal  authorization  processes  within  the  CNV  in  order  to  promote  the  development  of  local  capital  markets,  while  also 
generating  more  efficient  control.  The  main  benefit  for  frequent  issuers  such  as  YPF  is  that  the  new  regime  allows  them  to  significantly  reduce  the 
timeline of the offering process, which would in turn provide us with more flexibility and agility to take advantage of favorable market conditions in 
local and international markets. 

Under the Global Medium-Term Notes Program,  the Company issued several series  of  notes  in the local  and international  markets  at different 
interest  rates.  All  such  securities  are  authorized  to  be  traded  on  the  Buenos  Aires  Stock  Exchange  (Bolsa  de  Comercio  de  Buenos  Aires)  and  the 
Electronic  Open  Market  (Mercado  Abierto  Electrónico)  in  Argentina.  For  additional  information  about  the  outstanding  notes  of  YPF  S.A.  and  our 
controlled companies as of December 31, 2017, see Notes 4 and 16 to the Audited Consolidated Financial Statements.

We closely monitor our liquidity levels in order to attend cash needs from business operations and financial obligations. We have a conservative 
approach to the management of our liquidity which consists mainly of (i) cash and cash equivalents (cash in banks, liquidity funds and investments with 
a maturity of less than three months at the date of purchase), and (ii) other investments (fixed income securities, time deposits, and fund investments). 
We hold our liquidity primarily in U.S. dollars and in first-class financial entities. 

Description of Indebtedness 

As of December 31, 2018, our total consolidated debt was Ps. 335,078 million, of which 19% was current debt and 81% was non-current debt. 
Additionally, 86% of our total consolidated debt was denominated in U.S. dollars, 10% in Pesos and 4% in Swiss Francs. Moreover, 82% of our total 
consolidated  debt  accrues  interest  at  a  fixed  rate.  Regarding  our  debt  composition,  our  senior  notes  represent  78%,  while  the  remaining  22%  is 
represented by trade facilities and other loans. 

Uncommitted bank credit facilities together with debt capital markets provide a material source of funding for the Company. 

For detailed information regarding our indebtedness, see Notes 4 and 16 to the Audited Consolidated Financial Statements. 

Covenants in our indebtedness 

Our  financial  debt  generally  contains  customary  covenants  for  such  type  of  transaction  including,  among  other  things  and  subject  to  certain 
exceptions, not to establish liens or charges on our assets. In addition, approximately 56% of our debt outstanding as of December 31, 2018 was subject 
to financial covenants related to our leverage ratio and debt service coverage ratio. 

As of December 31, 2018, we were in compliance with all covenants in connection with our indebtedness. See “Item 3. Key Information—Risk 
Factors—Risks  Relating  to  Our  Business—If  we  fail  to  comply  with  the  covenants  set  forth  in  our  credit  agreements  and  indentures,  we  will  be  in 
default under such agreements and we may be required to repay all of our outstanding debt.” and “Certain of our outstanding financial indebtedness 
contains change of control provisions that may require us to prepay our debt.” 

Guarantees provided 

As  of  December 31,  2018,  in  relation  to  compliance  with  obligations  of  YPF  and  its  subsidiaries,  YPF  has  issued  bank  guarantees  for 
approximately U.S.$ 223 million (which include U.S.$ 200 million corresponding to corporate guarantees in favor of banks for borrowed money by our 
subsidiaries) and has assumed other commitments for an approximately U.S.$ 42 million. 

Additionally, see Note 29.e to the Audited Consolidated Financial Statements for a description of the Chevron transaction and see Note 16 to the 

Audited Consolidated Financial Statements for a description of the financial loans and notes secured by cash flows.

The expected timing for payments of the obligations in the preceding table is estimated based on current information. Timing of payments and 
actual  amounts  paid  may  be  different,  depending  on  the  time  of  receipt  of  goods  or  services,  or  changes  to  agreed-upon  amounts  for  some 
obligations. 
These projected amounts include interest due during all the periods presented. Interest on variable rate instruments is calculated using the rate as 
of  December 31,  2018  for  all  periods.  See  additionally  “Item  5.  Operating  and  Financial  Review  and  Prospects—Liquidity  and  Capital 
Resources—Covenants in our indebtedness.” 
Purchase obligations are obligations under contractual agreements to purchase goods or services, including capital projects. These obligations are 
enforceable and legally binding on YPF and specify all significant terms, including fixed or minimum quantities to be purchased; fixed, minimum, 
or variable price provisions; and the approximate timing of the transaction. For obligations with cancellation provisions, the amounts included in 
the  preceding  table  were  limited  to  the  non-cancellable  portion  of  the  agreement  terms or  the  minimum  cancellation  fee.  In  addition,  the  table 
includes purchase commitments under commercial agreements that do not provide for a total fixed amount, which have been valued using our best 
estimates. Accordingly, our actual purchase obligations may differ from the estimated amounts shown in the table. 
Some  of  our  purchase  orders  represent  authorizations  to  purchase  rather  than  binding  agreements.  In  that  regard,  we  have  entered  into  certain 
agreements for the purchase of products that specify minimum prices and quantities based on a percentage of the total available market or based 
on a percentage of our future purchasing requirements. Due to the uncertainty of the future market and our future purchasing requirements, as well 
as the non-binding nature of these agreements, obligations under these agreements have been excluded from the preceding table. Payments related 
to these obligations were not significant as of December 31, 2018. 
Provisions for contingent liabilities under commercial contracts, which amounted to U.S.$ 595 million as of December 31, 2018, are not included 
in the table above since we cannot, based on available evidence, reasonably estimate the settlement dates of such contingencies. 

(6) As a result of the extension of our concessions in certain exploration areas, we are committed to carrying out exploration activities and making 
certain investments and expenditures until the expiration of some of our concessions. The commitments for these investments and expenditures 
amounted to U.S.$ 9.7 billion as of December 31, 2018. The table includes the portion of this amount for which contracts have been executed. 
The table is presented in U.S.$, which is the Company’s functional currency. 
Includes  accounts  payable,  salaries  and  social  security,  taxes  payable,  provisions  for  pensions,  provisions  for  environmental  liabilities  and 
provisions  for  hydrocarbon  wells  abandonment  obligations  as  set  forth  in  our  audited  consolidated  financial  statements  included  as  of 
December 31, 2018.

We  have  additional  commitments  under  guarantees.  For  a  discussion  of  these  additional  commitments  see  “Item  5.  Operating  and  Financial 

Review and Prospects—Liquidity and Capital Resources—Guarantees provided.”

ITEM 6.

Directors, Senior Management and Employees 

Management of the Company 

On May 3, 2012, the Argentine Congress enacted the Expropriation Law. Among other matters, the Expropriation Law provided for the expropriation of 
51%  of  the  share  capital  of  YPF  represented  by  an  identical  stake  of  Class D  shares  owned,  directly  or  indirectly,  by  Repsol  and  its  controlled  or 
controlling entities. The shares subject to expropriation, which have been declared of public interest, will be assigned as follows: 51% to the Argentine 
Republic and 49% to the governments of the provinces that compose the National Organization of Hydrocarbon Producing States. To ensure compliance 
with its objectives, the Expropriation Law provides that the National Executive Office, by itself or through an appointed public entity, shall exercise all 
the political rights associated with the shares subject to expropriation until the transfer of political and economic rights to the provinces that compose the 
National Organization of Hydrocarbon Producing States is completed. 

172 

The Expropriation Law states that YPF shall continue as a publicly traded corporation and the management of the shares subject to expropriation shall 
be carried out according to the following principles: (i) strategic contribution of the Company to the aims established in the Expropriation Law; (ii) the 
management  of  the  Company  in  accordance  with  the  best  industry  and  corporate  governance  practices,  preserving  the  interests  of  the  Company’s 
shareholders and creating value for them; and (iii) the professional management of the Company. See “Item 4. Information on the Company—Legal and 
Regulatory Framework and Relationship with the Argentine Government—The Expropriation Law.”

The information provided below describes the responsibilities of our Board of Directors. 

Board practices of our Board of Directors 

In accordance with the Argentine General Corporations Law, directors have an obligation to perform their duties with loyalty and with the diligence of a 
prudent business person. Directors are jointly and severally liable to the Company, its shareholders and to third parties for the improper performance of 
their  duties,  for  violating  the  law  or  our  by-laws  or  regulations,  and  for  any  damage  caused  by  willful  misconduct,  abuse  of  authority  or  gross 
negligence. Specific duties may be assigned to a director by the by-laws, applicable regulations, or by shareholders resolution. In such cases, a director’s 
liability will be determined by reference to the performance of those specific duties so long as the director’s appointment and assignment of duties was 
approved at a shareholders’ meeting and was registered with the Superintendency of Corporations. 

Only shareholders, through a shareholders’ meeting, may authorize directors to engage in activities in competition with the Company. Transactions or 
contracts  between  directors  and  us  in  connection  with  our  activities  are  permitted  to  the  extent  they  are  performed  under  fair  market  conditions. 
Transactions that do not comply with the above requirements may only be carried out with prior approval of the Board of Directors or, in the absence of 
a  quorum  at  a  Board  of  Directors  meeting,  the  Supervisory  Committee.  In  addition,  these  transactions  must  be  subsequently  approved  by  our 
shareholders at a general meeting. If our shareholders do not approve the relevant transaction, the directors and members of the Supervisory Committee 
who approved the transactions will be held jointly and severally liable for any damages caused to us. 

Any  director  whose  personal  interest  conflicts  with  those  of  the  Company  on  any  matter  shall  notify  the  Board  of  Directors  and  the  Supervisory 
Committee and abstain from voting on the matter. Otherwise, such director may be held liable to the Company. 

A  director  will  not  be  liable  if,  notwithstanding  his  presence  at  the  meeting  at  which  a  resolution  is  adopted  or  his  knowledge  of  such  resolution,  a 
written record exists of his opposition to such resolution and he reports his opposition to the Supervisory Committee before any complaint against him is 
brought before the Board of Directors, the Supervisory Committee, the shareholders’ meeting, the appropriate governmental agency or judicial action is 
brought  to  the  courts.  Any  liability  of  a  director  to  us  terminates  upon  approval  of  the  director’s  actions  by  the  shareholders  at  a  general  meeting, 
provided  that  shareholders  representing  at  least  5%  of  our  capital  stock  do  not  object  and  provided  further  that  such  liability  does  not  result  from  a 
violation of the law, our by-laws or other regulations.

The Audit Committee 

The information provided below describes the composition and responsibilities of our Audit Committee. 

Composition and responsibilities of our Audit Committee 

The Capital Markets Law, as such term is defined in “Item 9. The Offer and Listing Argentine Securities Market,” and Resolution No. 622/2013 of the 
Argentine National Securities and Exchange Commission (Comisión Nacional de Valores) (“the CNV”) require Argentine public companies to appoint 
an Audit Committee (Comité de Auditoría) composed of at least three members of the Board of Directors. The by-laws must set forth the composition 
and  regulations  for  the  operation  of  the  Audit  Committee  and  a  majority  of  its  members  must  be  independent  directors.  Executive  directors  of  the 
Company are not permitted to sit on the Audit Committee. 

See “—Independence of the Members of our Board of Directors and Audit Committee.” 

The Board of Directors of the Company, at its meeting held on April 27, 2018, appointed the current members of the Audit Committee, who as of the 
date of this filing are: Carlos Felices, as chairman, and Daniel Gustavo Montamat and Emilio José Apud, as members. Additionally, Mr. Felices was 
determined by our Board of Directors to be an “Audit Committee Financial Expert” pursuant to the rules and regulations of the SEC. 

Our Audit Committee, among other functions: 

•

•

•

•

•

•

•

periodically inspects the preparation of our financial and economic information; 

reviews  and  opines  on  the  Board  of  Directors’  proposals  regarding  the  designation  of  the  external  auditors  and  the  renewal, 
termination and conditions of their appointment; 

evaluates internal and external audit work, monitors our relationship with the external auditors, and assures their independence; 

provides  complete  disclosure  regarding  transactions  where  a  conflict  of  interest  exists  with  members  of  the  corporate  bodies  or 
controlling shareholders; 

opines  on  the  reasonability  of  proposals brought  forth  by the Board of  Directors  on fees and  stock  option  plans  for directors  and 
administrators; 

verifies compliance with applicable national or international regulations for matters related to behavior in the stock markets; and 

ensures that the internal Code of Ethics complies with normative demands and is adequate. 

Activities of the Audit Committee 

The Audit Committee, pursuant to its regulations, must meet as many times as needed and at least once every quarter. Since April 2018 to the date of 
this annual report, the Audit Committee held 14 formal meetings. 

The Audit Committee must support the Board of Directors in its oversight duties, periodically review economic and financial information relating to us, 
supervise the internal financial control systems and oversee the independence of external auditors. 

Economic and financial information 

Using the assessment of the CFO and the work performed by our external and internal auditors, the Audit Committee analyzes the consolidated annual 
and  quarterly  financial  statements  before  they  are  submitted  to  the  Board  of  Directors.  The  Audit  Committee  reviewed  our  consolidated  financial 
statements as of and for the year ended December 31, 2018 included in our report on Form 6-K furnished to the SEC on March 15, 2019. 

182 

Oversight of the internal control system 

The  Audit  Committee  oversees  the  progress  of  our  annual  internal  audit,  which  is  aimed  at  identifying  critical  risks,  to  supervise  internal  financial 
control systems and ensure that they are sufficient, appropriate and efficient. 

Throughout the year, the Audit Committee is kept informed by our internal audit department of the most relevant facts and recommendations arising out 
of its work and the status of the recommendations issued. 

The Audit Committee supervised the alignment of our internal control system for financial reporting with the requirements established by Section 404 of 
the  Sarbanes-Oxley  Act.  These  regulations  require  that,  along  with  the  annual  audit,  a  report  must  be  presented  by  our  management  relating  to  the 
design, maintenance  and  periodic  evaluation of  the  internal  control  system for  financial  reporting and be  accompanied by  a  report  from  our external 
auditor. Several of our departments are involved in this activity, including the internal audit department. 

Relations with the external auditors 

The  Audit  Committee  interacts  closely  with  the  external  auditors,  allowing  them  to  make  a  detailed  analysis  of  the  relevant  aspects  of  the  audit  of 
financial statements and to obtain detailed information on the planning and progress of the work. 

The Audit Committee also evaluates the services provided by our external auditors, determines whether the conditions for independence of the external 
auditors, as required by applicable law, are met and monitors the performance of external auditors to ensure that it is satisfactory. 

As of the date of this annual report, and pursuant to the evaluation process described in the above paragraph, the Audit Committee had no objections to 
the designation of Deloitte & Co. S.A. as our external auditors of the financial statements for the year ended December 31, 2018. In addition, the Audit 
Committee, at its meeting held on March 6, 2019, as a result of the evaluation process outlined in the preceding paragraph, had no objections to the 
designation  of  Deloitte &  Co.  S.A.  as  our  external  auditors  for  the  year  ended  December 31,  2019,  which  will  be  considered  at  the  next  general 
shareholders’ meeting. 

Independence of the Members of our Board of Directors and Audit Committee 

The  following  described  CNV  regulations  were  taken  into  account  to  asses  a  director’s  independence.  In  that  sense,  a  director  is  not  considered 
independent when such director (i) owns at least a 15% equity interest in a company, or a lesser interest if the director has the right to appoint one or 
more  directors  of  the  company  (hereinafter  “Significant  Participation”),  or  has  a  Significant  Participation  in  another  company  that  in  turn  has  a 
Significant Participation in the company, or has a significant influence on the company (“significant influence” as defined by Argentine GAAP); (ii) is a 
member of the Board of Directors of, or depends on, or is otherwise related to shareholders who have a Significant Participation in the company or in 
other companies in which these shareholders have a direct or indirect Significant Participation or significant influence; (iii) is or has been in the previous 
three years an employee of the company; (iv) has a professional relationship with, or is a member of a company that maintains professional relationships 
with,  or  receives  remuneration  or  fees  (other  than  those  received  in  consideration  of  his  performance  as  a  director)  from  the  company  or  any  of  its 
shareholders who has a direct or indirect Significant Participation in or significant influence on the company, or with a third-party company that has a 
direct or indirect Significant Participation or a significant influence; (v) directly or indirectly sells or provides goods or services to the company or to 
any  of  its  shareholders  who  has  a  direct  or  indirect  Significant  Participation  in  or  significant  influence  on  the  company  for  an  amount  substantially 
exceeding his remuneration as a member of the Board of Directors or Audit Committee, as the case may be; or (vi) is the spouse or parent (up to second 
grade of affinity or up to fourth grade of consanguinity) of persons who, if they were members of the Board of Directors or Audit Committee, as the 
case may be, would not be independent, according to the above-listed rules. 

As of the date of this annual report, Directors Miguel Ángel Gutiérrez, Roberto Luis Monti, Norberto Alfredo Bruno, Néstor José Di Pierro, Ignacio 
Perincioli, Gabriel Alejandro Fidel, Sebastián Caldiero, Carlos Alberto Felices, Daniel Gustavo Montamat, Fabián Jorge Rodriguez Simón and Emilio 
José  Apud,  and  Alternate  Directors  Liliana  Amelia  Murisi,  Fernando  Martín  Cerdá,  Lucio  Mario  Tamburo  and  Miguel  Lisandro  Nieri  qualified  as 
independent members of our Board of Directors under the above-described criteria. 

On April 17, 2018, Resolution No. 730/2018 of the CNV became effective (“Resolution No. 730”). Said Resolution approved new criteria for assessing 
Directors independence and provides that companies that are obligated to have independent members within their board of directors should adjust their 
composition  to  these  new  criteria  in  the  first  ordinary  shareholders’  meeting  that  presents  financial  statements  to  be  held  after  December 31,  2018. 
Consequently,  the  independence  condition  of  our  Board  of  Directors  informed  herein  has  been  assessed  according  to  the  above  described  CNV 
regulations. 

183

Compliance with New York Stock Exchange Listing Standards on Corporate Governance 

In  accordance  with  the  NYSE  corporate  governance  rules,  effective  as  of  July 31,  2005,  all  members  of  the  Audit  Committee  are  required  to  be 
independent.  Independence  is determined in accordance with highly  detailed  rules  promulgated by  the NYSE and SEC. Each of the members of our 
Audit Committee was determined to be independent in accordance with the applicable NYSE and SEC rules. 

Significant differences between our corporate governance practices and those required by NYSE listing standards 

Non-U.S. NYSE-listed companies may, in general, follow their home country corporate governance practices in lieu of most of the NYSE corporate 
governance requirements. The NYSE rules, however, require that non-U.S. companies disclose any significant ways in which their specific corporate 
governance practices differ from those of U.S. companies under the NYSE listing standards. 

The following is a summary of the significant differences between our corporate governance practices and those applicable to U.S. companies under the 
NYSE listing standards. 

Independence of the directors on the Board of Directors 

In accordance with the NYSE corporate governance rules, a majority of the board of directors of U.S. companies listed on the NYSE must be composed 
of independent directors, whose independence is determined in accordance with highly detailed rules promulgated by the NYSE. The relevant Argentine 
rules  for  determining  director  independence  are  described  under  “—Independence  of  the  Members  of  our  Board  of  Directors  and  Audit  Committee” 
above. 

Compensation and nomination committee 

In  accordance  with  the  NYSE  corporate  governance  rules,  all  U.S.  companies  listed  on  the  NYSE  must  have  a  compensation  committee  and  a 
nomination committee and all members of such committees must be independent in accordance with highly detailed rules promulgated by the NYSE. 
Under  Argentine  law,  these  committees  are  not  mandatory,  but  are  recommended  by  the  CNV  under  CNV’s  General  Resolution  No. 622/13.  The 
Company  follows  the  CNV’s  recommendation  and  has  a  Nomination  and  Compensation  Committee  established  by  the  Board  of  Directors under  the 
option provided in Article 17 clause (xii) of the Company’s by-laws, which currently is composed of Directors Daniel Gustavo Montamat, Roberto Luis 
Monti, Carlos Alberto Felices and Fabián Jorge Rodríguez Simón. As a result of the foregoing, all the members of the Compensation and Nomination 
Committee are independent. 

Shareholder approval of equity compensation plans 

The  NYSE  rules  require  that,  with  limited  exemptions,  all  equity  compensation  plans  be  subject  to  a  shareholder  vote.  Under  Argentine  law,  the 
approval of equity compensation plans is within the authority of the Board of Directors. 

Separate meetings for non-management directors 

In  accordance  with  the  NYSE  corporate  governance  rules,  independent  directors  must  meet  periodically  outside  of  the  presence  of  its  executive 
directors. Under Argentine law, this practice is not required and as such, the independent directors on our Board of Directors do not meet outside of the 
presence of the other directors, except for the meetings of the Audit Committee, which is comprised of independent directors. 

186 

Compensation of members of our Board of Directors 

Argentine law provides that the aggregate annual compensation paid to the members of the Board of Directors (including those directors acting in an 
executive capacity) and of the members of the Shareholders’ Surveillance Committee (Consejo de Vigilancia), if applicable, with respect to a fiscal year 
may  not  exceed  5%  of  net  profit  for  such  year  if  YPF  is  not  paying  dividends  in  respect  of  such  net  income.  If  the  Company  pays  dividends,  that 
percentage is increased proportionally up to 25% of net income, based on the amount of such dividends. 

The Shareholders’ Surveillance Committee is a control entity regulated by the Argentine General Corporations Law, composed of shareholders of 
a  corporation.  As  of  the  date  of  this  annual  report,  YPF  does  not  have  a  Shareholders’  Surveillance  Committee  (Consejo  de  Vigilancia),  since  the 
Argentine General Corporations Law requires us to have a Supervisory Committee, composed of Statutory auditors. 

The compensation of the Chairman and other directors acting in an executive capacity, together with the compensation of all other directors and 
members of the Shareholders’ Surveillance Committee (Consejo de Vigilancia), if applicable, requires the approval of an ordinary general shareholders’ 
meeting as provided by Argentine law. When one or more directors exercise special commissions or technical administrative functions and there are 
reduced profits or there is a lack of them, and there is a need to exceed the abovementioned limits, such remunerations may only be paid in excess of 
those limits if expressly agreed by the shareholders’ meeting, for which purpose the matter should be included on the agenda. 

For  the  year  ended  December 31,  2018,  the  aggregate  compensation  accrued  by  the  members  of  the  Board  of  Directors  and  YPF’s  executive 
officers for services in all capacities was Ps. 406.2 million, excluding social security payments made by the Company as required by law, but including 
Ps.  68.9 million  in  the  form  of  equity  compensation  plans,  pensions,  retirement  or  similar  benefits  that  YPF  provides  to  its  Board  of  Directors  and 
executive  officers.  During  2018,  YPF’s  performance-based  compensation  programs  included  a  performance  bonus  program  for  approximately  7,100 
non-unionized YPF employees and 9,100 unionized YPF employees. This bonus program is intended to motivate and reward individuals for the annual 
achievement of business objectives. The program compensated participants in cash based on a measurable and specific set of objectives established by 
YPF’s Management by Objectives Program and individual performance results. 

In  2018,  our  shareholders’  meeting,  as  proposed  by  our  Board  of  Directors,  approved  the  creation  of  a  voluntary  reserve  of  Ps.  120 million  for  the 
fulfillment our long-term incentive plan which contemplates compensation in shares for certain employees. To that end, the Company purchased its own 
shares in accordance with Section 64 et seq. of Law No. 26,831. For additional information see Note 2.b.10.iii to our Audited Consolidated Financial 
Statements. The share-based benefit plan: (i) encourages key personnel to align their performance with the objectives of the Company’s strategic plan, 
(ii) generates a clear and direct link between the creation of shareholder value and compensation of key personnel, rewarding them for achieving long-
term results reflected in share price and (iii) assists in the retention of key personnel in the organization. 

YPF’s  directors  do  not  have  any  service  contracts  with  YPF  involving  the  payment  of  compensation  other  than  those  previously  mentioned  for  the 
performance  of their duties with the  Company. None of  the members  of our Board of  Directors are  party to any service contract  with  us or  any our 
subsidiaries providing for benefits upon termination of their term in office. 

Supervisory Committee 

The  Supervisory  Committee  is  responsible  for  overseeing  compliance  by  the  management  and  the  Board  of  Directors  with  Argentine  General 
Corporations  Law,  the  by-laws  and  regulations  (if  any),  and  shareholders’  resolutions.  The  functions  of  the  Supervisory  Committee  include,  among 
others,  attending  all  meetings  of  the  Board  of  Directors,  preparing  a  report  of  the  financial  statements  for  our  shareholders,  attending  shareholders’ 
meetings and providing information upon request to holders of at least 2% of our capital stock. 

The by-laws provide for a Supervisory Committee composed of three to five members and three to five alternate members that are elected for one-fiscal 
year term. The Class A shares are entitled to elect one member and one alternate member of the Supervisory Committee so long as one share of such 
class remains outstanding. The holders of Class D shares may elect up to four members and up to four alternates. Under the by-laws, meetings of the 
Supervisory Committee may be called by any member. The meetings require the presence of all members and a majority vote of the members in order to 
make  a  decision.  The  members  and  alternate  members  of  the  Supervisory  Committee  are  not  members  of  our  Board  of  Directors.  The  role  of  our 
Supervisory Committee is distinct from that of the Audit Committee. See “—The Audit Committee.” In 2018, the aggregate compensation paid to the 
members of the Supervisory Committee was Ps. 5.1 million.

Diversity and Inclusion 

Position
Director—President

Director

Director

YPF  operates  in  every  corner  of  Argentina  reaching  more  than  one  million  customers  per  day  through  its  network  of  gas  stations.  That  is  why  we 
believe  that  our  commitment  to  promoting  inclusion,  gender  equality  and  equal  opportunities  not  only  contributes  to  create  a  more  representative 
workforce  but  also  to  build  a  more  successful  and  profitable  company.  It  also  generates  a  positive  impact  on  all  those  with  whom  we  interact,  and 
contributes in favor of diversity and inclusion in society. 

We have taken important steps towards diversity and inclusion: 

We added Diversity as a strategic value in the 2017 Sustainability Report. 

We  incorporated  a  new  value  in  our  Code  of  Ethics  and  Conduct:  Gender  Equality  which  provides  that  YPF  guarantees  that  both  women  and  men 
receive  the  same  treatment  and  opportunities  to  grow  within  the  company,  with  identical  conditions  and  possibilities,  including  those  of  economic 
nature, for persons holding the same jobs. Besides, it ensures access to institutional programs and benefits in equality of conditions for both genders. 

Since  2016,  we  have  been  carrying  out  the  Training  Program  for  the  Employability  of  Persons  with  Disabilities,  in  conjunction  with  the  Labor  and 
Production Ministry. An initiative that gives participants the opportunity to perform qualifying and professionalizing practices in different areas of the 
company, guided by a YPF tutor, during a ten month period 

We  believe  that  access  to  work  is  key  to  inclusion,  and  based  on  that  belief  we  have  an  Inclusive  Procurement  Program  in  which  we  also  facilitate 
access to the YPF Suppliers network to organizations, cooperatives, protected workshops, associations and entities committed to the employability of 
people with physical, sensory or mental disability with skills to create and produce articles of aesthetic value, practical utility and / or attractive for the 
use. We believe that people with disabilities need the same opportunities as everyone else. 

During 2017, we invited more than 1,900 YPF women to participate in a survey to find out their opinion about diversity and its impact on the work 
environment. We also convened open talks in which men and women from our company, from all regions and businesses, shared with us their approach 
about gender equality. 

Thanks to an active collaboration and participation, we were able to identify ten areas in which women find obstacles to fully develop their careers. 

To  guarantee  equal  opportunities,  we  created  a  Diversity  Committee,  with  the  main  objectives  of  leading  the  implementation  of  gender  equality, 
removing those obstacles and foster Diversity and Inclusion across YPF. 

190 

This Committee developed and presents a 5-year plan that includes projects to promote and care for diversity and inclusion for our people and for 

our customers and suppliers. The plan is currently underway with the Diversity Committee monitoring its advance and results. 

On a yearly basis, overall focuses of the Action Plan are: 
2018 Start 
2019 Drive awareness 
2020 Extend 
2021 Change 
2022 Naturalize 

During  2018  we  moved forward  targeting  to  remove  the 10 main  obstacles  identified in  the  2017  survey: what  women find  when  onboarding, 
participation, promotion, remuneration and recognition in the industry, and promote and ensure the inclusion and full participation of women at YPF. 
Aiming to remove these obstacles by the end of 2020. 

We  are  currently  working  on  the  first  YPF  Diversity  Report  with  2018  results,  and  have  appointed  a  Diversity  Leader  to  coordinate  the 

implementation of the actions that bring us closer to a pluralistic YPF. 

We issued and communicated a Diversity Policy that establishes the expectations, commitments and requirements for inclusive behavior at YPF. 

It reflects our way of promoting diversity and inclusion and what is required of each person working at YPF to achieve it. 

We  have  scheduled  a  program  of  open  talks  about  gender,  innovation,  bias,  diversity  and  inclusion  to  discuss  and  sensibilize  our  workforce, 
organized  meetings  with  other  companies  and  organizations  to  promote  actions  in  favor  of  diversity  and  inclusion  and  joined  the  group  of  private 
companies that participate in the Gender Parity Initiative of the Federal Government. 

We  understand  leadership  is  fundamental  in  this  process  and  therefore  encourage  leaders  to  promote  diversity,  create  an  environment  of 

innovation, and integrate the plurality of thoughts and styles to position themselves as role models. 

Employee Matters 

Our  total  workforce  consists  of  permanent  and  temporary  employees.  As  of  December 31,  2016,  2017  and 2018,  we  had  19,257,  19,072 and  21,314 
employees,  respectively.  In  2018,  the  number  included  9,029  employees  in  the  Downstream  business  segment,  3,405  employees  in  the  Upstream 
business  segment,  1,568  employees  in  the  Gas &  Power  business  segment  and  7,312  employees  in  the  Central  Administration  and  Others  business 
segments. We had 1,672 temporary employees in 2018. The most significant variation in 2018 included an increase of employees at A-Evangelista S.A., 
by 1,791 employees during 2018 due to the implementation of new projects. Approximately 42% of our employees are represented by the Federation of 
Oil  Workers  Union  (“SUPeH”)  that  negotiates  labor  agreements  and  salaries  applicable  to  YPF  and  OPESSA  unionized  employees.  SUPeH  is 
continually  negotiating  with  us,  and  we  maintain  a  good  level  of  communication.  In  general,  requests  of  labor  unions  in  connection  with  the 
petrochemical industry were consistent with general wage increases given by the General Unions Confederation. 

191 

In  addition,  labor  conditions  and  salaries  of  third-party  employees  are  represented  by  sixteen  other  unions.  Approximately  49%  of  third-party 
employees,  mostly  in  the  Upstream  business,  are  represented  by  nine  unions  with  whom  we  directly  negotiate  labor  agreements  and  salaries.  These 
unions  are  clustered  into  three  groups:  Petroleros  Privados,  which  consists  of  five  unions,  Personal  Jerárquico,  which  consists  of  three  unions,  and 
SUPeH  Emprendimientos.  The  remaining  51%  of  third-party  employees  are  represented  by  unions  with  whom  we  do  not  participate  in  labor 
agreements. 

During 2016, YPF sought to create an addendum to the main Union’s Labor Agreements that would result in greater levels of efficiency, productivity 
and  sustainability  in  the  Shale  and  Tight  operations.  During  2017,  as  a  result  of  collaboration  with  the  main  actors  in  the  industry,  including  the 
Argentine government, provincial governors, Unions and representatives of the main production companies, YPF created and rolled out an addendum to 
the main union’s labor agreements that resulted in greater levels of efficiency, productivity and sustainability in the Shale and Tight operations. The 
addendum  was  signed  with  both  Neuquén  Unions  in  January  2017,  and  extended  to  the  Chubut  unions,  including  shale,  tight  and  conventional 
operations. By the end of 2017, similar agreements were reached individually with Santa Cruz’s main services companies. During 2018, as a result of 
collaboration with the main actors in the industry, including Neuquén authorities, and the Oil & Gas Unions, YPF came out with an “armor” to prevent 
strikes,  by  using  every  dispute  resolution  mechanism  included  in  Collective  Bargaining  Agreements.  During  the  first  quarter  of  2019  collective 
bargaining agreements with similar mechanisms were reached in Mendoza. 

As of December 31, 2018, YPF was a party to approximately 1,037 labor lawsuits related to events or acts that took place after December 31, 1990. The 
outcome of these lawsuits will depend on factual issues that vary from case to case, and it is not always feasible to predict the outcome of particular 
cases.  However,  based  on  the  number  and  nature  of  the  lawsuits  already  commenced,  the  estimated  likelihood  of  additional  claims  in  view  of  the 
number  of  dismissed  employees,  applicable  statutes  of  limitations,  the  legal  principles  involved  in  the  suits  and  the  financial  statement  reserves 
previously established, our management does not expect the outcome of these lawsuits to have a material adverse effect on our financial condition or 
future results of operations. 

As of December 31, 2018, there were also approximately 43,000 third-party employees under contract, mostly with large international service providers. 
Although we have policies regarding compliance with labor and social security obligations for our contractors, we are not in a position to ensure that the 
contractors’  employees  will  not  initiate  legal  actions  against  us  seeking  indemnification  based  upon  a  number  of  Argentine  judicial  labor  court 
precedents  that  recognized  joint  and  several  liability  between  the  contractor  and  the  entity  to  which  it  was  supplying  services  under  certain 
circumstances.

Major Shareholders and Related Party Transactions 

The  Expropriation  Law  has  significantly  changed  our  shareholding  structure.  The  Class D  shares  subject  to  expropriation  from  Repsol  or  its 
controlling or controlled entities, which represent 51% of our share capital and have been declared of public interest, will be assigned as follows: 51% to 
the  Argentine  Republic  and  49%  to  the  governments  of  the  provinces  that  compose  the  National  Organization  of  Hydrocarbon  Producing  States.  In 
addition, the Argentine Republic and certain provincial governments already own our Class A and Class B shares. See “Item 3. Key Information—Risk 
Factors—Risks  Relating  to  Argentina—  The  Argentine  federal  government  owns  51%  of  the  shares  of  the  Company.”  Additionally,  see  “Item  4. 
Information on the Company—Legal and Regulatory Framework and Relationship with the Argentine Government—Law No. 26,932” for a description 
of the agreement between Repsol and the Argentine Republic relating to compensation for the expropriation of 51% of the share capital of YPF owned, 
directly or indirectly, by Repsol. As of the date of this annual report, the transfer of the shares subject to expropriation between the National Executive 
Office  and  the  provinces  that  compose  the  National  Organization  of  Hydrocarbon  Producing  States  is  still  pending.  According  to  Article  8  of  the 
Expropriation Law, the distribution of the shares among the provinces that accept their transfer must be conducted in an equitable manner, taking into 
account  their  respective  levels  of  hydrocarbon  production  and  proved  reserves.  To  ensure  compliance  with  its  objectives,  the  Expropriation  Law 
provides  that  the  National  Executive  Office,  by  itself  or  through  an  appointed  public  entity,  shall  exercise  all  the  political rights  associated  with  the 
shares  subject  to  expropriation  until  the  transfer  of  political  and  economic  rights  to  the  provinces  that  compose  the  National  Organization  of 
Hydrocarbon  Producing  States  is  completed.  In  addition,  in  accordance  with  Article  9  of  the  Expropriation  Law,  each  of  the  Argentine  provinces  to 
which shares subject to expropriation are allocated must enter into a shareholder’s agreement with the federal government which will provide for the 
unified exercise of its rights as a shareholder. See “Item 4. Information on the Company—Legal and Regulatory Framework and Relationship with the 
Argentine Government—The Expropriation Law.”

The  expropriated  Class D  shares,  which  represent  51%  of  our  share  capital,  and  which  now  are  owned  by  the  Republic  of  Argentina,  will  be 
assigned  as  follows:  51%  to  the  Argentine  Republic  and  49%  to  the  governments  of  the  provinces  that  compose  the  National  Organization  of 
Hydrocarbon Producing States. The completion of this assignment is pending. To ensure compliance with its objectives, the Expropriation Law 
provides that the National Executive Office, by itself or through an appointed public entity, shall exercise all the political rights associated with 
the shares subject to expropriation until the transfer of political and economic rights to the provinces that compose the National Organization of 
Hydrocarbon Producing States is completed. In addition, in accordance with Article 9 of the Expropriation Law, each of the Argentine provinces

Argentine Law Concerning Related Party Transactions 

Section 72  of  the  Capital  Markets  Law  provides  that  before  a  company  whose  shares  are  listed  in  Argentina  may  enter  into  an  act  or  contract 
involving a “significant amount” with a related party or parties, such company must obtain approval from its Board of Directors, and obtain an opinion, 
prior to such board approval, from its audit committee or from two independent valuation firms that states that the terms of the transaction are consistent 
with those that could be obtained on an arm’s-length basis. 

For the purpose of Section 72 of the Capital Markets Law and CNV Regulations, “significant amount” means an amount that exceeds 1% of the 
issuer’s net worth as reflected in the latest approved financial statements. For purposes of the Capital Markets Law, “related party” means (i) directors, 
members of the Supervisory Committee or managers; (ii) the persons or entities that control or hold a significant participation in the company or in its 
controlling shareholder (as regulated by CNV); (iii) any other company under common control; (iv) direct relatives of the persons mentioned in (i) and 
(ii); or (v) companies in which the persons referred to in (i) to (iv) hold directly or indirectly significant participations. 

The acts or contracts referred to above, immediately after being approved by the board of directors, shall be disclosed to the CNV, making express 
indication  of  the  audit  committee’s  or  independent  valuation  firm’s  opinion,  as  the  case  may  be.  Also,  on  the  business  day  following  the  day  the 
transaction was approved by the board of directors, the Audit Committee’s or the independent valuation firms’ report, as the case may be, shall be made 
available to the shareholders at the Company’s principal executive offices. 

If  the  Audit  Committee  or  the  two  independent  valuation  firms  do  not  find  that  the  contract  is  on  arm’s-length  terms,  prior  approval  must  be 

obtained at the Company’s shareholders’ meeting, prior to the transaction.

Argentine Securities Market 

The securities market in Argentina was originally composed of 5 stock exchanges, which are located in the City of Buenos Aires (the “BASE”), 
Córdoba, Mendoza, Rosario and Santa Fe, with affiliated stock markets and, accordingly, authorized to quote publicly offered securities. However, this 
system  was  affected  by  the  enactment  of  Law  No. 26,831,  Decree  No  1,203/2013  issued  by  the  National  Executive  Office  and  the  new  regulations 
issued by the CNV, mainly contained in Resolution No. 622/2013, as amended, which stated that securities can only be listed and exchanged in stock 
markets authorized to function as such by the CNV. 

195 

The BASE, which began operating in 1854, was the principal and longest-established stock exchange in Argentina. The exchange functions of the 
BASE have now been absorbed by the S&P MERVAL, which is a stock market authorized by the CNV to function as such, under Law No. 26,831. The 
S&P MERVAL and the BASE have entered into an agreement which has been approved by the CNV, whereby the S&P MERVAL has delegated to the 
BASE  certain  functions,  such  as:  (i) the  authority  to  grant  listing  authorization  for  securities;  (ii) the  authority  to  constitute  arbitration  courts;  and 
(iii) the issuance of a public information bulletin. 

On December 29, 2016, the Board of Directors of the CNV approved the creation of Bolsas y Mercados Argentinos (“ByMA”) as a new market. 

The shareholders of ByMA are the S&P MERVAL and BASE, with each holding 60% and 40% of the capital stock of ByMA, respectively. 

The Argentine securities market is regulated and overseen by the CNV, pursuant to Law No. 26,831 (the “Capital Markets Law”) which governs the 
regulation of securities exchanges, as well as stockbroker transactions, market operations, the public offering of securities, corporate governance matters 
relating to public companies and the trading of futures and options. Argentine institutional investors and insurance companies are regulated by separate 
government agencies, whereas financial institutions are regulated primarily by the Argentine Central Bank. 

In Argentina, debt and equity securities traded on an exchange or the over-the-counter market must, unless otherwise instructed by their shareholders, be 
deposited with Stock Exchange Incorporated (Caja de Valores S.A.), a corporation owned 99.96% by Bolsas y Mercados Argentinos S.A. (“ByMA”). 
Stock  Exchange  Incorporated  is  the  central  securities  depositary  of  Argentina  and  provides  central  depositary  facilities,  as  well  as  acting  as  a 
clearinghouse  for securities trading and as a transfer and paying  agent for securities transactions. Additionally, it handles the settlement of securities 
transactions carried out by the ByMA and operates through Millenium. 

Among  the  key  provisions  of  the  Capital  Markets  Law  are  the  following:  the  definition  of  a  “security,”  that  governs  the  treatment  of  negotiable 
securities; the corporate governance requirements, including the obligations for publicly listed companies to form audit committees composed of three 
or more members of the Board of Directors (the majority of whom must be independent under CNV regulations); regulations for market stabilization 
transactions under certain circumstances, regulations that governs insider trading, market manipulation and securities fraud and regulates going-private 
transactions  and  acquisitions  of  voting  shares,  including  controlling  stakes  in  public  companies.  In  addition,  the  Capital  Markets  Law  includes 
provisions regarding the demutualization of the stock exchanges; new regulatory powers and resources for the CNV; a mandatory tender offer system – 
as well as regulations for voluntary tender offers—and other provisions, like new requirements for brokers/dealers and other market participants. These 
provisions were regulated by the CNV pursuant to General Resolution No. 622/2013, as amended. Before offering securities to the public in Argentina, 
an issuer must fulfill certain requirements established by the CNV in regard to the issuer’s assets, operating history and management. Only securities 
approved for a public offering by the CNV may be listed on an authorized market. However, CNV approval does not imply any kind of certification as 
to  the  quality  of  the  securities  or  the  solvency of  the  issuer,  even  though  issuers  of  listed  securities  are  required  to  file  unaudited quarterly  financial 
statements and audited annual financial statements in accordance with IFRS and various other periodic reports with the CNV and the authorized market 
on which their securities are listed, as well as to report to the CNV and the relevant authorized market any event related to the issuer and its shareholders 
that may materially affect the value of the securities traded. 

Admission to the ByMA Corporate Governance Plus Panel 

The Company has been admitted to the special panel denominated “Corporate Governance Plus Panel” (CG+ Panel) created by ByMA. 

ByMA’s Corporate Governance Panel is a new market segment which shall be composed by companies who voluntarily adhere to increased standards 
of good corporate governance and transparency than those required under Argentine regulations and who assume the commitment to their monitoring on 
a periodic basis. Such standards are in line with the corporate governance principles of the Organization for Economic Co-operation and Development 
(OECD), which were adopted by the G20. 

Anti-Money laundering and Terrorism Prevention regulations 

Modifications to Argentine money laundering regulations have resulted in their application to increasing numbers and types of securities transactions. 

196 

The  notion  of  money  laundering  is  generally  used  to  refer  to  transactions  aimed  at  introducing  funds  derived  from  unlawful  activities  into  the 
institutionalized system and therefore, transforming profits obtained from unlawful activities into assets having a presumed lawful origin. 

Law  No. 25,246  (as  subsequently  amended  by  Law  No. 26,087,  Law  No. 26,119,  Law  No. 26,268  and  Law  No  26,683),  Law  No. 26,374  and  Law 
No. 27,446) provides for an administrative criminal system and replaces several sections of the Argentine Criminal Code, incorporating, among other 
matters, the definition of money laundering as a type of crime committed whenever a person converts, transfers, manages, sells, charges, conceals or 
otherwise markets any asset derived from a criminal offense, with the possible consequence that the original assets or substitutes thereof appear to come 
from a lawful source, provided that the total value of the asset exceeds Ps. 300,000 regardless of whether such amount results from one act or a series of 
related acts. Law No. 26,683 considers money laundering to be an autonomous crime against the economic and financial order, separate from the crime 
of  concealment,  which  is  an  offense  against  the  public  administration,  which  allows  for  sanctions  for  the  autonomous  crime  of  money  laundering 
regardless of participation in the crime that originated the funds subject to such money laundering. With the enactment of Law No. 27,260 and Decree 
No. 895/2016,  the  Financial  Information  Unit  (Unidad  de  Información  Financiera  or  “UIF”)  was  moved  under  the  jurisdiction  of  the  Ministry  of 
Finance and Public Finance. Subsequently, in accordance with Decree No. 2/2017, the UIF acts under the jurisdiction of the Ministry of Finance. 

According  to  Article  303  of  the  Argentine  Criminal  Code,  money  laundering  (as  defined  above)  shall  be  punished  with  three  to  ten  years  of 
imprisonment and a fine of two to ten times the amount of the transactions made. The penalty prescribed above shall be increased by one third of the 
maximum and one half of the minimum if: (a) the wrongdoer carries out the act on a regular basis or as a member of an association or gang organized 
with the purpose of continuously committing acts of a similar nature; or (b) if the primary wrongdoer is a public officer who committed the infringement 
in the exercise of his/her duties (in such a case, the wrongdoer shall also be punished by special disqualification for three to ten years, and the same 
penalty shall apply to a wrongdoer who commits the offense in the service of a profession or trade requiring special qualification). The individual who 
receives money or other assets derived from a criminal offense with the purpose of applying them to a money laundering transaction shall be punished 
with imprisonment from six months to three years. If the value of the assets is not over Ps. 300,000, the wrongdoer will be punished with imprisonment 
from  six  months  to  three  years.  The  provisions  in  this  section  shall  apply  even  when  the  criminal  offense  is  committed  outside  the  geographical 
jurisdiction of the Argentine Criminal Code, so long as the crime is also penalized in the jurisdiction where it was committed. 

Article  277  of  the  Argentine  Criminal  Code  sets  forth  that  an  imprisonment  of  between  six  months  and  three  years  shall  be  applied  (with  varying 
minimum  terms  attaching  depending  on  the  particular  circumstances)  to  any  person  who  helps  a  perpetrator  avoid  or  be  removed  from  prosecution, 
obscures or destroys evidence of a crime, acquires, receives, hides or alters money or other proceeds from a crime, does not report the commission of the 
crime or does not identify the perpetrator or participant in a crime with knowledge that such person would have been obliged to assist in the criminal 
prosecution  of  such  crime  and/or  aids  or abets  the  perpetrator  or  participant  in  making  safe  the  proceeds  of  the  crime.  The  minimum  and  maximum 
terms of punishment shall be doubled when: (a) the offense implies a particularly serious crime (for which minimum penalty is higher than three years 
of imprisonment); (b) the abettor acts for profit; (c) the abettor habitually commits concealment acts; or (d) the abettor is a public official. 

At the end of 2011, with the enactment of Laws No. 26,733 and 26,734, new crimes were introduced into the Argentine Criminal Code to protect 
financial and stock market activities and to prevent the financing of terrorism. On the one hand, Law No. 26,733 established penalties of imprisonment, 
fines and special disqualification for anyone who: uses or supplies inside information to conduct securities transactions (Article 307); manipulates stock 
markets by offering or conducting securities transactions through false information, feigned negotiations or meeting of the main shareholders in order to 
negotiate at a certain price (Article 308); and carry out financial and stock market activities without corresponding authorization (Article 309). On the 
other hand, Law No. 26,734 incorporated into the Argentine Criminal Code Article 306, which punishes with imprisonment and fines those who directly 
or indirectly collect assets or money to be used to finance a crime or an individual or organization that threatens the population, or to force national or 
foreign authorities or an international organization to perform or refrain from performing a particular act. The penalties will apply regardless of whether 
the crime was committed, or the financing was used. Additionally, the penalties will apply if the crime, individual or organization that is intended to be 
financed is carried out or located outside of Argentina. Likewise, the UIF was empowered to freeze assets linked to the financing of terrorism through a 
reasoned decision and immediate communication to a competent judge. 

Law No. 25,246 contemplates that the legal entity whose management collected or provided assets or money, whatever their value, knowing that such 
assets were to be used by a terrorist organization, may be subject to a fine between five to 20 times the value of such assets. Furthermore, whenever the 
management of the legal entity infringes the duty to treat the information submitted to the UIF as confidential, the legal entity shall be subject to a fine 
between  Ps.  50,000  to  Ps.  500,000.  Additionally,  such  regulation  created  the  UIF  as  an  autonomous  and  financially  self-sufficient  entity  within  the 
jurisdiction of the Argentine Ministry of Justice and Human Rights, in charge of analyzing, treating and transmitting information in order to preclude 
and prevent money laundering. Pursuant to this legislation, 

197 

the UIF  is empowered  to  receive and  request reports,  documents,  background  and  any other  information  deemed  useful  to fulfill  its  duties  from  any 
public  entity,  whether  federal,  provincial  or  municipal,  and  from  individuals  or  public  or  private  entities,  all  of  which  entities  must  furnish  such 
information  in  accordance  with  Law  No. 25,246.  Whenever  the  information  furnished,  or  analyses  performed  by  the  UIF  show  the  existence  of 
sufficient  evidence  to  suspect  that  a  money  laundering  or  terrorist  financing  crime  has  been  committed,  the  UIF  shall  transmit  such  evidence  to  the 
Government  Attorney’s  Office  so  that  it  may  start  the  relevant  criminal  action,  and  the  UIF  may  appear  as  an  accusing  party  to  such  proceedings. 
Moreover,  Law  No. 26,087  mandates  that  banking  secrecy  or  professional  privilege,  or  legal  or  contractual  commitments,  cannot  be  considered 
exceptions to the compliance with the obligation to submit information to the UIF in the context of an investigation of suspicious activity. The main goal 
of Law No. 25,246 is to prevent money laundering and the financing of terrorism. In line with internationally accepted practices, the duty to control such 
illegal transactions is not concentrated solely in Argentine federal governmental entities but also distributed among several private sector entities such as 
banks, brokers, brokerage firms and insurance companies. One of the mechanisms of the regime of preventing and combating these crimes consists of 
the obligation to inform the UIF imposed by Article 20 of the Prevention of Money Laundering Law to those parties listed that, due to their profession, 
activity or industry, hold a key position in the detection of suspicious money-laundering operations and/or terrorist financing transactions. Such duties 
mainly  consist  of  data  collection  functions,  such  as:  (i) gathering  from  clients,  applicants  or contributors  any  documentation sufficient  to  prove  their 
identity, legal capacity, domicile and further data as necessary on a case by case basis; (ii) reporting any suspicious fact or transaction irrespective of its 
amount; and (iii) abstaining from disclosing to the client or third parties any procedures being followed pursuant to law. According to Law No. 25,246, a 
suspicious  transaction  shall  mean  any  transaction  that,  in  accordance  with  standard  business  practices  and  in  the  experience  of  the  entities  and 
individuals subject to reporting obligations, is regarded as unusual, unjustified from an economic or legal standpoint, or unnecessarily complex, whether 
it is a one-time transaction or a series of transactions. 

In February 2016, the National Executive Office issued Decree No. 360/2016, through which it creates, under the jurisdiction of the Ministry of 
Justice and Human Rights, and directly dependent on its leadership, the “National Coordination Program in the Fight against Money Laundering and 
Terrorist  Financing,”  with  the  mission  of  reorganizing,  coordinating  and  strengthening  the  national  anti-money  laundering  system  and  against  the 
financing  of  terrorism,  attending  to  the  specific  risks  that  could  impact  national  terrorism  and  effective  global  exigencies  in  compliance  with 
international  obligations  and  recommendations  established  by  the United  Nations  Conventions  and  the  standards  of  the  Financial  Action  Task  Force 
(“FATF”). By virtue of Article 6 of Decree No. 360/2016, the UIF will act as the coordinator in the material operation of the national, provincial and 
municipal order in the strict compliance of its duties as a financial information organization. 

Resolution No. 30-E/2017 of the UIF (“Resolution 30”), which became effective on September 15, 2017, abrogated Resolution No. 121/2011 and set 
forth new obligations that financial entities subject to Law No. 21,526 and exchange entities subject to Law No. 18,924, as amended (the “Resolution 30 
Reporting Parties”), must observe in their capacity as reporting parties pursuant to article 20, paragraphs 1 and 2, of Law No. 25,246. Resolution 30 
follows the International Standards on Combating Money Laundering and the Financing of Terrorism and Proliferation issued by the Financial Action 
Task Force in 2012, with the purpose of adopting a risk-based approach to ensure that measures to prevent or mitigate money laundering and terrorist 
financing are commensurate with the risks identified. 

Among other duties and obligations, Resolution 30 provided that Resolution 30 Reporting Parties must: (i) develop and document the risk identification 
and  assessment  methodology  they  will  implement  in order  to  identify,  evaluate,  mitigate  and  monitor  their  ML/TF  (as  defined  below)  risks,  prior  to 
December 31,  2017;  (ii)  have  a  technical  report  reflecting  the  results  of  the  implementation  of  the  methodology  described  in  (i) above,  prior  to 
March 31, 2018; and (iii) have adjusted their policies and procedures, as set forth in Resolution 30, and in accordance with the results of the risk self-
assessment  performed  (which  policies  should  be  incorporated  into  the  Resolution  30  Reporting  Party’s  money  laundering  and  financing  of  terrorism 
(“ML/FT”) Prevention Manual (as defined below). 

Resolution No. 229/2011 of the UIF, as amended by UIF Resolutions No. 52/2012, 140/2012, 104/2016, 141/2016 and 4/2017 (“Resolution 229”), is 
applicable to Stockbrokers and stockbrokerage firms, companies managing mutual funds, over-the-counter market agents, and all those intermediaries 
engaged  in  the  purchase,  lease  or  borrowing  of  securities  trading  in  the  field  of  stock  exchanges  with  or  without  markets  attached  to  them  and 
intermediaries registered with futures and options markets, whichever their purpose may be (“Resolution 229 Reporting Parties”, and together with the 
Resolution 30 Reporting Parties, the “Reporting Parties”). Resolution 30 and Resolution 229 regulate, among other matters, (i) the obligation to collect 
certain documentation from clients, (ii) the obligations and internal restrictions to be implemented for purposes of complying with their duty to report 
suspicious  ML/TF  operations  and  (iii) know  your  customer  (KYC)  policies  (including  the  distinction  between  regular  and  occasional  clients), 
information  which  must  be  requested  from  clients,  documentation  storage  requirements  and  the  procedures  for  purposes  of  detecting  and  reporting 
suspicious transactions. 

Pursuant  to  Resolution  30  and  Resolution  229,  the  Reporting  Parties’  main  duties  consist  of:  a)  implementing  a  manual  (the  “Prevention  Manual”), 
based on the Reporting Party’s particular activities, setting forth the mechanisms and procedures to be used to prevent ML/TF; b) the designation of a 
compliance officer pursuant to article 20 bis of Law 25,246, as amended, and article 20 of Decree 

198 

No. 290/07,  as  amended;  c)  the  implementation  of  periodic  audits;  d)  personnel  training;  e)  elaborating  and  maintaining  analysis  records  and  risk 
management of detected unusual operations and operations reported because they were considered suspicious; f) implementation of technological tools 
to have efficient control systems and be able to prevent money laundering and terrorism financing; and g) implementation of measures that allow the 
Reporting  Parties,  respectively,  to  electronically  consolidate  the  operations  they  perform  with  clients,  as  well  as  technological  tools,  which  enable 
analyzing or monitoring different variables to identify certain behaviors and detect possible suspicious operations. The Reporting Parties must report to 
the  UIF  any  suspicious  transaction  within  30  calendar  days  from  the  day  a  transaction  is  qualified  as  a  suspicious  transaction  on  money  laundering 
grounds (and regardless of whether the action was completed or attempted) and any suspicious transaction on terrorism financing grounds of within 48 
hours of its occurrence. 

Resolution 30 defines (i) “unusual transactions” as those which lack economic and/or legal justification, whether attempted or performed in isolation or 
repeatedly, regardless of their amount, do not correspond to the client’s risk or transactional profile, or that, due to their frequency, recurring nature, 
amount,  complexity,  nature  and/or  other  particular  characteristics,  deviate  from  standard  market  practices,  and  (ii)  “suspicious  transactions”  as  those 
operations,  whether  attempted  or  performed,  that  cause  a  suspicion  of  ML/FT  activities,  or  that  have  previously  been  identified  as  an  unusual 
transaction,  and  after  the  analysis  and  evaluation  carried  out  by  the  Reporting  Party,  cannot  be  justified.  Resolution  229  defines  (i)  “unusual 
transactions” as those operations that are attempted or carried out in isolation or repeatedly, without economic and/or legal justification, and that do not 
relate  to  the  risk  or  transactional  profile  of  the  client  or  deviate  from  standard  market  practices,  due  to  their  frequency,  recurring  nature,  amount, 
complexity, nature and/or particular characteristics, and (ii) “suspicious transactions” as those operations that are attempted or carried out that cause a 
suspicion of ML/FT activities, or that have previously been identified as an “unusual transaction”, and after the analysis and evaluation carried out by 
the Reporting Party, they create a doubt about the authenticity, veracity or coherence of the documentation presented by the client, in relation to their 
activity.  Pursuant  to  Resolution  30,  financial  entities  have  the  duty  to  (i) implement  an  ML/FT  prevention  system  (the  “Prevention  System”),  which 
must  contain  all  the  policies,  procedures  and  controls  established  for  ML/FT  risk  management  to  which  they  are  exposed,  and  the  elements  of 
compliance required by such resolution and (ii) constitute an anti-ML/FT prevention committee. 

Furthermore, Resolution 30 modified compliance officers’ duties and required entities to upload the following reports through the UIF website: (a) a 
report  of  cash  transactions  in  excess  of  Ps.  200,000;  (b)  a  report  detailing  international  transfers  from  and  to  Argentine  accounts;  and  (c) an  annual 
systematic report. 

Resolution  No. 92/2016  of  the  UIF  imposed  on  the  reporting  parties  the  obligation  to  implement  a  risk  management  system  in  accordance  with  the 
“voluntary and exceptional  affidavit of holding  of national currency, foreign currency  and other assets  in the country or abroad” established by Law 
No. 27,260, in order to report suspicious transactions performed by clients until March 31, 2017, derived from the tax amnesty regime. 

In addition, the CNV rules, under Title XI of “Prevention of Money Laundering and Terrorist Financing,” establish that brokers and brokerage firms, 
and  companies  managing  common  investment  funds,  agents  of  the  over-the-counter  market,  intermediaries  in  the  purchase  or  lease  of  securities 
affiliated  with  stock  exchange  entities  with  or  without  associated  markets  and  intermediary  agents  registered  on  forwards  or  option  markets,  and 
individuals or legal entities acting as trustees, for any type of trust fund, and individuals or legal entities, owners of or related to, directly or indirectly, 
with  trust  accounts,  trustees  and  grantors  in  the  context  of  a  trust  agreement,  shall  comply  with  Law  No. 25,246,  the  UIF’s  rulings  and  the  CNV’s 
regulations. Additionally, companies managing common investment funds, any person acting as placement agent or performing activities relating to the 
trading of common investment funds, any person acting as placement agent in any primary issuance of marketable securities, and any issuer with respect 
to capital contributions, irrevocable capital contributions for future issuances of stock or significant loans, must also comply with such regulations. 

Such  resolutions  also  contain  certain  requirements  for  the  reception  and  delivery  of  checks  and  payments  made  between  the  individuals  and  entities 
listed above, as well as the prohibition of transactions relating to the public offering of securities, when they are consummated or ordered by individuals 
or  companies  domiciled  or  residing  in  domains,  jurisdictions,  territories  or  associated  states  not  included  in  the  list  of  Decree  No. 589,  as  amended 
(regulating mainly the jurisdictions which are considered “cooperatives for fiscal transparency purposes”). 

Brokers and dealers must duly know their clients and apply policies and maintain adequate structures and systems in line with a policy against money 
laundering and terrorist financing. Also, interested investors undertake the obligation to submit any information and documents that may be required in 
order  to  comply  with  criminal  regulations  and  other  laws  and  regulation  in  connection  with  money  laundering,  including  capital  market  regulations 
preventing money laundering issued by the UIF and similar regulations issued by the CNV. 

199 

According to the regulations related to the prevention of money laundering, the financing of terrorism and other illicit activities issued by the Central 
Bank, financial entities should take certain measures with respect to its clients, including, without limitation: 

•

•

•

•

•

•

observe the regulations governing the collection of proceeds, the legislation applicable to these matters (laws and regulatory decrees) and 
the regulations of the UIF. This includes the decrees of the National Executive Office with reference to the decisions adopted by the United 
Nations Security Council in combatting terrorism and comply with the resolutions (and their respective annexes) issued by the Ministry of 
Foreign Affairs and Worship; 

in the absence of documentation or the existence of doubts and/or the detection of irregularities regarding veracity, accuracy, coherence or 
integrity  of  the  documents  provided  by  the  clients,  or  because  situations  have  been  detected  that  deviate  from  the  customer  profile  (as 
determined  in  accordance  with  existing  regulations),  require  additional  information  and/or  documentation,  indicating  to  the  client  the 
obligation to comply with such additional requests; 

under  no  circumstance  can  relationships  with  new  clients  be  carried  out  until  the  provisions  of  current  regulations  regarding  the 
identification and knowledge of the client, and risk management are duly complied with; 

in  the  case  of  existing  clients  in  respect  of  which  identification  and  knowledge  could  not  be  complied  with  in  accordance  with  the 
regulations in force, an analysis should be made with a risk-based approach, in order to assess the continuity of the relationship with the 
client. In September 2016, Communication “A” 6,060 of the BCRA came into force, which set forth that the criteria and procedures to be 
applied  in  this  process  must  be  described  by  the  financial  entities  in  their  Prevention  Manual.  If  it  is  appropriate  to  discontinue  the 
relationship with a client, the procedures and deadlines established by the provisions of the Argentine Central Bank that are specific to the 
applicable product(s) must be observed. The reporting subjects must keep the written records of the procedures applied in each case where 
they discontinue the relationship with a client, for a period of 10 years; 

send a certified copy of the designation of the regular and alternate chief compliance officer, if any, to the UIF of the Central Bank, carried 
out in accordance with the conditions and within the terms established in the regulations issued by the UIF; 

keep  a  database  with  information  corresponding  to  clients  that  perform  individual  operations  for  amounts  equal  to  or  greater  than  Ps. 
240,000 (or its equivalent in other currencies) for certain concepts. The scope of this obligation will also include cases relating to customers 
who, in the opinion of the intervening entity, carry out related-party operations that do not reach the minimum threshold on an individual 
basis,  but  exceed  or  reach  such  amount  in  the  aggregate.  For  such  purpose,  they  are  also  required  to  store  information  corresponding  to 
persons who conduct transactions which in the aggregate during any day are equal to or greater than Ps. 30,000 (or its equivalent in other 
currencies). 

Failure to comply with the requirements established by the BCRA to access the local exchange market for transactions involving the purchase and 

sale of securities of all types constitute an infraction subject to the criminal exchange regime. 

In addition, in November 2016, BCRA Communication “A” 6,094 established that the regulations of the prevention of money laundering, terrorist 
financing and other illicit activities issued by the Central Bank must also be complied with by the foreign representatives of the financial entities that are 
not authorized to operate in Argentina. 

Through the enactment of Law No. 27,260 and its related regulations and Decree No. 895/2016, the UIF was granted the power to communicate 
information to other public entities with intelligence or investigation powers, provided that such powers can only be exercised following a well-founded 
resolution issued by the UIF’s president and solely in those case where there are serious, precise and concordant signs regarding the commission of any 
of  the  crimes  set  forth  by  Law  No. 25,246.  Any  information  provided  by  the  UIF  will  be  transferred  along  with  the  obligation  to  maintain  secrecy 
pursuant to Article 22 of Law No. 25,246, and any unlawful disclosure of confidential information by any entity will be subject to certain penalties. The 
UIF will not exercise the authority referred to in cases related to voluntary and exceptional declarations made under Law No. 27,260. 

On June 18, 2018, by means of Law No. 27,446, modifications to numerous sections of the Anti-Money Laundering Law were introduced, with 
the purpose of simplifying and streamlining judicial proceedings, adapting the regulations in force to the operative reality of the UIF and to adopt certain

Law No. 27,401 on Corporate Criminal Liability 

On  November 8,  2017,  a  law  establishing  the  criminal  liability  regime  applicable  to  private  legal  entities,  state-owned  or  not,  was  enacted  by  the 
Argentine Congress and published in the Official Gazette of the Argentine Republic on December 1, 2017 (the “Corporate Criminal Liability Law”). 
The law entered into force in March 2018, 90 days following its publication. 

The  Corporate  Criminal  Liability  Law  applies  to  private  legal  entities  for  the  crimes  of  national  and  transnational  bribery  and  influence  peddling; 
transactions that are incompatible with the exercise of public offices; and illegal exaction committed by public officials; among others. 

Legal entities are liable for those crimes, carried out directly or indirectly, with their intervention or in their name, interest or benefit. The legal entity is 
also liable if a third party, without any capacity to act on its behalf, acted in its own benefit or interest, provided the legal entity has ratified the third 
party’s acts, even implicitly. 

In the event of transformation, merger, absorption, spin-off or any other corporate restructuring, the legal entity’s responsibility will be transferred to the 
resulting or absorbing legal entity. 

The  law  also  provides  that  the  legal  entity  may  be  convicted  even  if  the  individual  involved  could  not  be  identified  or  judged,  provided  that  the 
circumstances of the case allow establishing that the crime could not have been committed without the acquiescence of the legal entity’s bodies. 

The penalties that could be applicable to legal entities included fines, total or partial suspension of business activities of up to ten (10) years, suspension 
from participating in public bids or tenders for the execution of public works or services, dissolution and winding up of the legal entity under certain 
circumstances, loss or suspension of government benefits, among others. 

Penalties can be graduated by judges, who will contemplate the compliance of internal rules and procedures, the number and hierarchy of the officials, 
employees and collaborators involved; the lack of surveillance; the extent of damage caused; the amount of money involved; the willingness to reduce 
or repair the damage and recidivism. 

The  legal  entity  will  be  exempted  from  penalties  and  administrative  liability  provided  that:  a)  It  has  self-reported  an  offense  under  the  Corporate 
Criminal  Liability  Law;  b)  It  has  implemented  an  adequate  monitoring  and  supervision  system  (Compliance  Program),  prior  to  the  fact  under 
prosecution occurred, and c) It has returned the undue benefit obtained. 

The Ministerio Público Fiscal (Public Prosecutor’s Office) and the legal entity may enter into an effective collaboration agreement, whereby the latter 
undertakes to cooperate by disclosing data or information for the clarification of the facts, the identification of the participants and/or the recovery of the 
assets or profits proceeding from the crime, as well as to comply with the other conditions established by the Corporate Criminal Liability Law. 

Legal entities are not required under the Corporate Criminal Liability Law to implement Compliance Programs with the exception of those entering into 
certain  agreements  with  the  Government.  The  Compliance  Programs  shall  include  a  set  of  internal  actions,  mechanisms  and  procedures  to  promote 
integrity, supervision and control aimed at preventing, detecting and correcting irregularities and unlawful acts under this law. 

ITEM 10.

Additional Information 

Capital Stock 

Our capital stock consists of Ps.3,933,127,930, divided into 3,764 Class A shares, 7,624 Class B shares, 40,422 Class C shares and 393,260,983 Class D 
shares, each fully subscribed and paid, with a par value of ten pesos each and the right to one vote per share. Our total capital stock has not changed 
since December 31, 2004. 

In  November  1992,  the  Privatization  Law  became  effective.  Pursuant  to  the  Privatization  Law,  in  July  1993,  we  completed  a  worldwide  offering  of 
160 million Class D shares, representing approximately 45% of our outstanding capital stock, which had been 

201 

owned  by  the  Argentine  government.  Concurrently  with  the  completion  of  such  offering,  the  Argentine  government  transferred  approximately 
40 million  Class B  shares  to  the  Argentine  provinces,  which  represented  approximately  11%  of  our  outstanding  capital  stock,  and  made  an  offer  to 
holders of pension bonds and certain other claims to exchange such bonds and other claims for approximately 46.1 million Class B shares, representing 
approximately 13% of our outstanding capital stock. As a result of these transactions, the Argentine government’s ownership percentage of our capital 
stock was reduced from 100% to approximately 30%, including shares that had been set aside to be offered to our employees upon establishment of the 
terms and conditions by the Argentine government in accordance with Argentine law. The shares set aside to be offered to employees represented 10% 
of our outstanding capital stock. 

In July 1997, the Class C shares set aside for the benefit of our employees in conjunction with the privatization, excluding approximately 1.5 million 
Class C shares set aside as a reserve against potential claims, were sold through a global public offering, increasing the percentage of our outstanding 
shares  of  capital  stock  held  by  the  public  to  75%.  Proceeds  from  the  transactions  were  used  to  cancel  debt  related  to  the  employee  plan,  with  the 
remainder distributed to participants in the plan. Additionally, Resolution No. 1,023/06 of the Ministry of Economy, dated December 21, 2006, effected 
the transfer to the employees covered by the employee share ownership plan, or PPP, of 1,117,717 Class C shares, corresponding to the Class C shares 
set aside as a reserve against potential claims, and reserving 357,987 Class C shares until a decision was reached in a pending lawsuit. Subsequently, 
with  a  final  decision  having  been  reached  in  the  lawsuit,  and  consistent  with  the  mechanism  of  conversion  of  Class C  shares  into  Class D  shares 
established  by  Decree  628/1997  and  its  accompanying  rules,  as  of  December 31,  2009,  1,447,983  Class C  shares  had  been  converted  into  Class D 
shares. In 2010, a former employee of the Company who was allegedly excluded from the Argentine government’s YPF PPP filed a claim against YPF 
seeking  recognition  of  his  status  as  a  shareholder  of  YPF.  In  addition,  the  Federation  of  Former  Employees  of  YPF  joined  the  proceeding  as  a 
supporting  third-party  claimant,  purportedly  acting  on  behalf  of  other  former  employees  who  were  also  allegedly  excluded  from  the  PPP.  Under  the 
jurisprudence of the CSJN upholding numerous decisions of the relevant Argentine Courts of Appeals, YPF believes it will not be held liable for claims 
of this nature related to the PPP. Through Law No. 25,471, the Argentine government assumed sole responsibility for any compensation to be received 
by YPF’s former employees who were excluded from the PPP. 

The  Expropriation  Law  has  significantly  changed  our  shareholding  structure.  The  Class D  shares  subject  to  expropriation  from  Repsol  YPF  or  its 
controlling or controlled entities, which represent 51% of our share capital and were declared of public interest and are currently held by the Republic of 
Argentina,  will  be  assigned  as  follows:  51%  to  the  Argentine  federal  government  and  49%  to  the  governments  of  the  provinces  that  compose  the 
National Organization of Hydrocarbon Producing States. In addition, the Argentine federal government and certain provincial governments already own 
our Class A and Class B shares. See “Item 3. Key Information—Risk Factors—Risks Relating to Argentina—The Argentine Republic owns 51% of the 
shares of the Company.” 

See Note 25 to the Audited Consolidated Financial Statements, “Item 4. Information on the Company—History and Development of YPF,” “Item 4. 
Information on the Company—Legal and Regulatory Framework and Relationship with the Argentine Government—The Expropriation Law,” “Item 4. 
Information on the Company—Legal and Regulatory Framework and Relationship with the Argentine Government—Decree No. 272/2015” and “Item 
7. Major Shareholders and Related Party Transactions.” 

Memorandum and Articles of Association 

YPF’s by-laws were approved by National Executive Decree No. 1,106, dated May 31, 1993, and notarized by public deed No. 175, dated June 15, 1993 
at  the  National  Notary  Public  Office,  sheet  801  of  the  National  Registry,  and  registered  at  the  Inspection  Board  of  Legal  Entities  of  the  Argentine 
Republic on the same date, June 15, 1993 under number 5,109 of the book of Corporations number 113, volume “A.” 

At a shareholders’ meeting on April 29, 2016, YPF’s shareholders approved an amendment to YPF’s by-laws. Copies of the by-laws, which have been 
filed as Exhibit 1.2. to YPF’s 2016 annual report on Form-20 filed on April 7, 2017, are also available at the offices of YPF. 

For a detailed description of YPF’s object and purpose, see “Item 4. Information on the Company.” YPF’s object is set forth in Section 4 of its by-laws. 

Pursuant to Argentine General Corporations Law, the Board of Directors or the Supervisory Committee shall call either annual general or extraordinary 
shareholders’  meetings  in  the  cases  provided  by  law  and  whenever  they  consider  appropriate.  Shareholders  representing  not  less  than  5%  of  YPF’s 
capital stock may also request that a shareholders’ meeting be called. 

202 

A  shareholders’  meeting  shall  be  called  at  least  twenty  calendar  days  –  and  no  more  than  45  calendar  days—prior  to  the  meeting  date  by  notice 
published in the legal publications journal for a period of five days. The notice shall include the nature, date, time and place of the meeting, the agenda 
to be discussed and the specific requirements shareholders must meet to attend the meeting. 

Shareholders’ Meetings 

As previously noted, pursuant to the Argentine General Corporations Law, the Board of Directors or the Supervisory Committee shall call either annual 
ordinary or extraordinary shareholders’ meetings in the cases provided by law and whenever they consider appropriate. Shareholders representing not 
less than 5% of our capital stock may also request that a shareholders’ meeting be called, in which case the meeting must be held within 40 days of such 
shareholders’ request. If the Board of Directors or the Supervisory Committee fails to call a meeting following such a request, a meeting may be ordered 
by the CNV or by the courts. 

Shareholders’  meetings  may  be  ordinary  meetings  or  extraordinary  meetings.  The  Company  is  required  to  convene  and  hold  an  ordinary  meeting  of 
shareholders within  four  months  of  the closing of  each fiscal  year to  consider the matters specified  in the  first two  paragraphs of  Section 234  of the 
Argentine  General  Corporations  Law,  such  as  the  approval  of  our  financial  statements,  allocation  of  net  profit  for  such  fiscal  year,  approval  of  the 
reports of the Board of Directors and the Audit Committee and the election, performance and remuneration of directors and members of the Supervisory 
Committee. In addition, pursuant to the Capital Markets Law, at ordinary shareholders’ meetings, shareholders must consider (i) the disposition of, or 
creation of any lien over, all or substantial part of the assets of the Company as long as such decision has not been performed in the ordinary course of 
business  and  (ii) the  execution  of  administration  or  management  agreements  and whether  to  approve  any  agreement  by  virtue  of  which  the  assets or 
services  provided  to  the  Company  are  paid  partial  or  totally  with  a  percentage  of  our  income,  results  or  earnings,  if  the  payment  is  material  when 
measured against the volume of the ordinary course of business and our shareholders’ equity. Other matters which may be considered at an ordinary 
shareholders’  meeting  convened  and  held  at  any  time  include  the  responsibility  of  directors  and  members  of  the  Supervisory  Committee,  capital 
increases and the issuance of certain notes. Extraordinary shareholders’ meetings may be called at any time to consider matters beyond the authority of 
an ordinary meeting including, without limitation, the amendment of our by-laws, issuance of debentures, early dissolution, merger, spin-off, reduction 
of capital stock and redemption of shares, transformation from one type of entity to another and limitation or suspension of shareholders’ preemptive 
rights. 

Notices of meetings 

Notice  of  shareholders’  meetings  must  be  published  for  five  days  in  the  Official  Gazette,  in  an  Argentina  newspaper  of  wide  circulation  and  in  the 
bulletin of the BASE, at least 20 but not more than 45 calendar days prior to the date on which the meeting is to be held. Such notice must include 
information  regarding  the  type  of  meeting  to  be  held,  the  date, time  and  place of  such  meeting  and  the  agenda.  If  a  quorum  is  not  available at  such 
meeting, a notice for a meeting on second call, which must be held within 30 days of the date on which the first meeting was called, must be published 
for three days at least eight days before the date of the meeting on second call. The above-described notices of shareholders’ meetings may be affected 
simultaneously  for  the  meeting  on  second  call  to  be  held  on  the  same  day  as  the  first  meeting,  only  in  the  case  of  ordinary  meetings.  Shareholders’ 
meetings may be validly held without publication of the call if all the shares of our outstanding share capital are present and resolutions are adopted by 
unanimous vote of shares entitled to vote. 

Quorum and voting requirements 

Except as described below, the quorum for ordinary meetings of shareholders on first call is a majority of the shares entitled to vote, and action may be 
taken by the affirmative vote of an absolute majority of the shares present that are entitled to vote on such action. If a quorum is not available at the first 
meeting, a meeting on second call may be held at which action may be taken by the holders of an absolute majority of the shares present, regardless of 
the number of such shares. The quorum for an extraordinary shareholders’ meeting on first call is 60% of the shares entitled to vote, and if such quorum 
is not available, a meeting or second call may be held with the presence of 30% of the shares entitled to vote, and in both cases action may be taken by 
the holders of an absolute majority of the shares present, regardless of the number of such shares. 

Our by-laws establish that in order to approve (i) the transfer of our domicile outside Argentina, (ii) a fundamental change of the corporate purpose set 
forth in our by-laws, (iii) delisting of our shares from the BASE or NYSE, and (iv) a spin-off by us, when as a result of such spin-off more than 25% of 
our assets are transferred to the resulting corporations, a majority of the shares representing 75% or more of our voting shares is required, both in first 
and  second  call.  Our  by-laws  also  establish  that  in  order  to  approve  (i) certain  amendments  to  our  by-laws  concerning  tender  offers  of  shares  (as 
described  below),  (ii)  the  granting  of  certain  guarantees  in  favor  of  our  shareholders,  (iii) full  stop  of  refining,  commercialization  and  distribution 
activities and (iv) rules regarding appointment, election and number of members of our Board of Directors, a majority of the shares representing 66% or 
more of our voting shares is required, both in first and second call, as is the affirmative vote of the Class A shares, voting at a special meeting of the 
holders of such shares. 

203 

In order to attend the meeting, shareholders must deposit their shares, or a certificate representing book-entry shares issued by a bank, clearing house or 
depository trust company, with us. This certificate will allow each shareholder to be registered in the attendance book which closes three business days 
before  the  date on which  the  meeting  will be  held.  The  Company  will  issue  to  each  shareholder  a  deposit certificate  required  for  admission  into  the 
meeting. Shares certified and registered in the attendance book may not be disposed of before the meeting is held unless the corresponding deposit is 
cancelled. 

Under the Argentine General Corporations Law, foreign companies that own shares in an Argentine corporation are required to register in the National 
Corporations Registry (held by the Ministry of Justice and Human Rights, or the agency to be determined by such ministry to that effect, according to 
Decree  No.  27/2018—published  on  January 11,  2018  in  the  Official  Gazette)  in  order  to  exercise  certain  shareholder  rights,  including  voting  rights. 
Such registration requires the filing of certain corporate and accounting documents. Accordingly, if a shareholder owns Class D shares directly (rather 
than in the form of ADSs) and it is a non-Argentine company, and such shareholder fails to register in the National Corporations Registry, the ability to 
exercise its rights as a holder of Class D shares may be limited. 

Directors,  members  of  the  Supervisory  Committee  and  senior  managers  are  both  entitled  and  required  to  attend  all  shareholders’  meetings.  These 
persons may only exercise voting power to the extent they have been previously registered as shareholders, in accordance with the provisions described 
in the above paragraph. Nevertheless, these persons are not allowed to vote on any proposal regarding the approval of their management duties or their 
removal for cause. 

Shareholders who have a conflict of interest with the Company and who do not abstain from voting may be liable for damages to us, but only if the 
transaction would not have been approved without such shareholders’ votes. Furthermore, shareholders who willfully or negligently vote in favor of a 
resolution that is subsequently declared void by a court as contrary to the law or our by-laws may be held jointly and severally liable for damages to us 
or to other third parties, including shareholders. 

Our major shareholders do not have different voting rights. 

Directors 

Election of Directors 

Our  business  and  affairs  are  managed  by  the  Board  of  Directors  in  accordance  with  our  by-laws  and  the  Argentine  General  Corporations  Law.  Our 
by-laws provide for a Board of Directors of 11 to 21 members, and up to an equal number of alternates. Alternates are elected by the shareholders to 
replace directors who are absent from meetings or who are unable to exercise their duties, when and for whatever period appointed to do so by the Board 
of Directors. Alternates have the responsibilities, duties and powers of Directors only if and to the extent they are called upon to attend board meetings 
and as long as they perform duties of a Director. 

Directors  hold  office  from  one  to  three  fiscal  years,  as  determined  by  the  shareholders’  meetings.  In  accordance  with  our  by-laws,  the  Argentine 
government, as sole holder of Class A shares, is entitled to elect one director and one alternate. 

Under the Argentine General Corporations Law, a majority of our directors must be residents of Argentina. All directors must establish a legal domicile 
in Argentina for service of notices in connection with their duties. 

The  Argentine  General  Corporations  Law  and  our  by-laws  require  the  Board  of  Directors  to  meet  at  least  once  every  quarter  in  person  or  by  video 
conference,  and  a  majority  of  directors  is  required  in  order  to  constitute  a  quorum.  If  a  quorum  is  not  met  one  hour  after  the  start  time  set  for  the 
meeting, the  President or his substitute may invite alternates of the same class as that of the absent directors to join the meeting until the quorum is 
reached,  or  call  a  meeting  for another  day.  Resolutions  must  be  adopted  by  a  majority  of  the  directors  present,  and  the  President  or  his  substitute  is 
entitled to cast the deciding vote in the event of a tie. Our Directors are not required to hold any shares in us, and there is no age limit requirement for 
the retirement or non-retirement of our Directors. 

According to our by-laws, the Board of Directors shall have wide powers to organize, conduct and manage the affairs of the Corporation. Specifically, it 
is  empowered to approve  the annual budget, expenditure and investment estimates, the necessary borrowing  levels  and  the annual action plan of the 
Corporation. 

204 

Duties and liabilities of Directors 

In accordance with the Argentine General Corporations Law, directors have an obligation to perform their duties with loyalty and with the diligence of a 
prudent  business  person.  Directors  are  jointly  and  severally  liable  to  us,  our  shareholders  and  to  third  parties  for  the  improper  performance  of  their 
duties, for violating the law or our by-laws or regulations, and for any damage caused by fraud, abuse of authority or gross negligence. Specific duties 
may be assigned to a director by the by-laws, company regulations, or by resolution of the shareholders’ meeting. In such cases, a director’s liability will 
be determined by reference to the performance of such duties. 

Only  shareholders,  through  a  shareholders’  meeting  may  authorize  directors  to  engage  in  activities  in  competition  with  us.  Transactions  or  contracts 
between directors and us in connection with our activities are permitted to the extent they are performed under fair market conditions. Transactions that 
do  not  comply  with  the  Argentine  General  Corporations  Law  require  prior  approval  of  the  Board  of  Directors  or  the  Supervisory  Committee.  In 
addition, these transactions must be subsequently approved by the shareholders at a general meeting. If our shareholders do not approve the relevant 
transaction, the directors and members of the Supervisory Committee who approved such transactions are jointly and severally liable for any damages 
caused to us. 

Any director whose personal interests are averse to ours, shall notify the Board of Directors and the Supervisory Committee and abstain from voting on 
such matters. Otherwise, such director may be held liable to us. 

A director will not be liable if, notwithstanding his presence at the meeting at which a resolution was adopted or his knowledge of such resolution, a 
written record exists of his opposition to such resolution and he reports his opposition to the Supervisory Committee before any complaint against him is 
brought before the Board of Directors, the Supervisory Committee, the shareholders’ meeting, the appropriate governmental agency or the courts. Any 
liability  of  a  director  to  us  terminates  upon  approval  of  the  director’s  actions  by  the  shareholders  at  a  general  meeting,  provided  that  shareholders 
representing at least 5% of our capital stock do not object and provided further that such liability does not result from a violation of the law, our by-laws 
or other regulations. 

Foreign Investment Legislation 

Under  the  Argentine  Foreign  Investment  Law,  as  amended,  and  its  implementing  regulations  (together,  referred  to  as  the  “Foreign  Investment 
Legislation”),  the  purchase  of  shares  of  an  Argentine  corporation  by  an  individual  or  legal  entity  domiciled  abroad  or  by  an  Argentine  company  of 
“foreign capital” (as defined in the Foreign Investment Legislation) constitutes foreign investment. Currently, foreign investment in industries other than 
broadcasting, purchase land located in frontier and other security areas by foreigners and limits on the ownership of rural land by foreign individuals or 
legal entities according to Law 26,737, is not restricted, and no prior approval is required to make foreign investments. No prior approval is required in 
order to purchase Class D shares or ADSs or to exercise financial or corporate rights thereunder. 

Dividends 

Under our by-laws, all Class A, Class B, Class C and Class D shares rank equally with respect to the payment of dividends. All shares outstanding as of 
a particular record date share equally in the dividend being paid, except that shares issued during the period to which a dividend relates may be entitled 
only to a partial dividend with respect to such period if the shareholders’ meeting that approved the issuance so resolved. No provision of our by-laws or 
of the Argentine General Corporations Law gives rise to future special dividends only to certain shareholders. 

The amount and payment of dividends are determined by majority vote of our shareholders voting as a single class, generally, but not necessarily, on the 
recommendation of the Board of Directors. In addition, under the Argentine General Corporations Law, our Board of Directors has the right to declare 
dividends subject to further approval of the shareholders’ meeting. 

Although we have not adopted a formal policy regarding dividends, we intend to maintain the practice of an annual distribution, within the framework 
of  a  management  that  will  also  consider,  among  other  factors,  the  capital  requirements  related  to  investment  plans,  the  attention  of  debt  services, 
working capital needs, legal and / or contractual restrictions that apply at all times, and the general conditions of the economic and financial context. At 
the shareholders’ ordinary and extraordinary general meeting held on April 29, 2016, a dividend of Ps. 889 million (Ps. 2.26 per share or ADS) was 
authorized for distribution by December 31, 2016, which was paid in July 2016. At the shareholders’ ordinary and extraordinary general meeting held 
on April 28, 2017, a dividend of Ps. 716 million (Ps. 1.82 per share or ADS) was authorized and paid in December 2017. At the shareholders’ ordinary 
and  extraordinary  general  meeting  held  on  April 27,  2018,  a  dividend  of  Ps.  1,200 million  (Ps.  3.05  per  share  or  ADS)  was  authorized  and  paid  in 
December 2018. On March 7, 2019, the 

205 

Board decided to propose the following to the General Ordinary Shareholders’ Meeting: (i) allocate the sum of Ps. 280 million to constitute a Reserve 
for  the  purchase  of  own  shares,  in  order  to  grant  the  Board  the  possibility  of  acquiring  shares  owned  at  the  time  it  deems  appropriate,  and  comply, 
during the execution of the plans, with the commitments generated and to be generated by it in the future, (ii) allocate the sum of Ps. 33,235 million to 
constitute a reserve for investments in the terms of Article 70, third paragraph of the Argentine General Corporations Law, and (iii) allocate the sum of 
Ps.  4,800 million  to  a  reserve  for  future  dividends,  empowering  the  Board  of  Directors,  up  to  the  date  of  the  next  Ordinary  General  Shareholders 
Meeting that deals with the Financial Statements for the period ended December 31, 2019, to determine the opportunity and amount for its distribution, 
taking  into account the financial  and  availability  of funds as  well  as operating  results, investments  and  other aspects that  it  considers  relevant  in the 
development  of  the  activities  of  the  Company,  or  its  application  in  accordance  with  the  provisions  of  article  224  second  paragraph  of  the  General 
Companies Act and other applicable regulations. 

The following table sets forth for the periods and dates indicated, the dividend payments made by us, expressed in pesos.

Amount Available for Distribution 

Under Argentine law, dividends may be lawfully paid only out of our retained earnings reflected in the annual audited financial statements prepared in 
accordance with accounting rules prevailing in Argentina and CNV regulations and approved by a shareholders’ meeting. The Board of Directors of a 
listed Argentine company that makes public offering of its shares may declare interim dividends, based on special or quarterly financial statements with 
the report of the external auditor and the Supervisory Committee, in which case the members of the Board and of the Supervisory Committee are jointly 
and severally liable for the repayment of such dividend if retained earnings at the close of the fiscal year in which the interim dividend was paid would 
not have been sufficient to permit the payment of such dividend. 

According to the Argentine General Corporations Law and our by-laws, the Company is required to maintain a legal reserve of at least 5% of the fiscal 
year’s income until such reserve equals 20% of our then-outstanding capital stock. The legal reserve is not available for distribution to shareholders. 

Under our by-laws, the Company’s liquid and realized profits are applied as follows:

first, at least 5% of net income, plus (less) prior year adjustments, is segregated to build the legal reserve until such reserve is equal to 20% 
of our subscribed capital; 

second, an amount is segregated to pay the accrued fees of the members of the Board of Directors and of the Supervisory Committee. See 
“Item 6. Directors, Senior Management and Employees—Compensation of members of our Board of Directors”; 

third, an amount is segregated to pay dividends on preferred stock, if any; and 

206 

•

fourth, the remainder of net profit in whole or in part may be distributed as dividends to common shareholders or allocated for voluntary or 
contingent reserves as determined by the shareholders’ meeting. 

Our  Board  of  Directors  submits  the  Company’s  financial  statements  for  the  preceding  fiscal  year,  together  with  reports  thereon  by  the  Supervisory 
Committee and the external auditor, at the annual ordinary shareholders’ meeting for approval. Within four months of the end of each fiscal year, an 
ordinary shareholders’ meeting must be held to consider our yearly financial statements and determine the allocation of our net profit for such year. 

Under  applicable  CNV  regulations,  cash  dividends  must  be  paid  to  shareholders  within  30  days  from  the  shareholders’  meeting  approving  such 
dividends. In cases where the shareholders meeting delegates the authority for the distribution of dividends to the Board of Directors, the Company has 
consistently paid the declared dividends within 30 days from the relevant Board of Directors’ resolution. In the case of payment of stock dividends, or 
payment  of  both  stock  and  cash  dividends,  both  shares  and  cash  are  required  to  be  available  within  three  months  of  the  receipt  of  notice  of  the 
authorization  of  the  CNV  for  the  public  offering  of  the shares  arising  from such  dividends.  In  accordance  with  the Argentine  Civil  and  Commercial 
Code, the statute of limitations to the right of any shareholder to receive dividends declared by the shareholders’ meeting is five years from the date on 
which it has been made available to the shareholder. However, according to Article 2,537 of the Argentine Civil and Commercial Code, the statute of 
limitations on the right of any shareholder to receive dividends declared before August 1, 2015 is three years. 

Owners of ADSs are entitled to receive any dividends payable with respect to the underlying Class D shares. Cash dividends are paid to the Depositary 
in pesos, directly or through BoNY, as depositary, although the Company may choose to pay cash dividends outside Argentina in a currency other than 
pesos, including U.S. dollars. The deposit agreement provides that the Depositary shall convert cash dividends received by the Depositary in pesos to 
dollars, to the extent that, in the judgment of the Depositary, such conversion may be made on a reasonable basis, and, after deduction or upon payment 
of the fees and expenses of the Depositary, shall make payment to the holders of ADSs in U.S. dollars. 

Preemptive and Accretion Rights 

Except as described below, in the event of a capital increase, a holder of existing shares of a given class has a preferential right to subscribe a number of 
shares  of  the  same  class  sufficient  to  maintain  the  holder’s  existing  proportionate  holding  of  shares  of  that  class.  Preemptive  rights  also  apply  to 
issuances  of  convertible  securities,  but  do  not  apply  upon  conversion  of  such  securities.  Pursuant  to  the  Argentine  General  Corporations  Law,  in 
exceptional cases and on a case-by-case basis when required for the best interest of the Company, the shareholders at an extraordinary meeting with a 
special  majority  may  decide  to  limit  or  suspend  shareholders’  preemptive  rights,  provided  that  such  limitation  or  suspension  of  the  shareholders’ 
preemptive rights is included in the agenda of the meeting and the shares to be issued are paid in kind or are issued to cancel preexisting obligations. 

Under its by-laws, the Company may only issue securities convertible into Class D shares, and the issuance of any such convertible securities must be 
approved by a special meeting of the holders of Class D shares. 

Holders  of  ADSs  may  be  restricted  in  their  ability  to  exercise  preemptive  rights  if  a  registration  statement  under  the  Capital  Markets  Law  relating 
thereto  has not  been  filed or is  not  effective.  Preemptive rights  are  exercisable  during  the  30  days following the last  publication  of notice informing 
shareholders of their right to exercise such preemptive rights in the Official Gazette and in an Argentine newspaper of wide circulation. Pursuant to the 
Argentine General Corporations Law, if authorized by an extraordinary shareholders’ meeting, companies authorized to make public offering of their 
securities, such as YPF, may shorten the period during which preemptive rights may be exercised from 30 to 10 days following the publication of notice 
of the offering to the shareholders to exercise preemptive rights in the Official Gazette and a newspaper of wide circulation in Argentina. Pursuant to our 
by-laws,  the  terms  and  conditions  on  which  preemptive  rights  may  be  exercised  with  respect  to  Class C  shares  may  be  more  favorable  than  those 
applicable to Class A, Class B and Class D shares. 

Shareholders who have exercised their preemptive rights have the right to exercise accretion rights, in proportion to their respective ownership, with 
respect to any non-preempted shares, in accordance with the following procedure: 

•

•

Any non-preempted Class A shares will be converted into Class D shares and offered to holders of Class D shares that exercised preemptive 
rights and indicated their intention to exercise additional preemptive rights with respect to any such Class A shares. 

Any  non-preempted  Class B  shares  will  be  assigned  to  those  provinces  that  exercised  preemptive  rights  and  indicated  their  intention  to 
exercise  accretion rights  with  respect to  such  shares;  any  excess will be  converted  into  Class D  shares and  offered  to  holders  of  Class D 
shares that exercised preemptive rights and indicated their intention to exercise accretion rights with respect to any such Class B shares. 

207 

•

•

Any non-preempted Class C shares will be assigned to any PPP participants who exercised preemptive rights and indicated their intention to 
exercise  accretion rights  with  respect to  such  shares;  any  excess will be  converted  into  Class D  shares and  offered  to  holders  of  Class D 
shares that exercised preemptive rights and indicated their intention to exercise accretion rights with respect to any such Class C shares. 

Any non-preempted rights will be assigned to holders of Class D shares that exercised their preemptive rights and indicated their intention 
to exercise accretion rights; any remaining Class D shares will be assigned pro rata to any holder of shares of another class that indicated his 
or her intention to exercise accretion rights. 

The term for exercise of additional preemptive rights is the same as that fixed for exercising preemptive rights. 

Voting of the Underlying Class D Shares 

Under the by-laws, each Class A, Class B, Class C and Class D share entitles the holder thereof to one vote at any meeting of the shareholders of YPF, 
except  that  a  specified  number  of  Directors  is  elected  by  majority  vote  of  each  class  (except  as  provided  below).  See  “—Directors—Election  of 
Directors” above for information regarding the number of directors that holders of each class of shares are entitled to elect and certain other provisions 
governing  nomination  and  election  of  directors.  The  Depositary  has  agreed  that,  as  soon  as  practicable  after  receipt  of  a  notice  of  any  meeting  of 
shareholders of YPF, it will mail a notice to the holders of ADRs, evidencing ADSs, registered on the books of the Depositary which will contain the 
following: 

•

•

•

a summary in English of the information contained in the notice of such meeting; 

a statement that the holders of ADRs at the close of business on a specified record date will be entitled, subject to any applicable provisions 
of Argentine law, the by-laws of YPF and the Class D shares, to instruct the Depositary to exercise the voting rights, if any, pertaining to the 
Class D shares evidenced by their respective ADSs; and 

a statement as to the manner in which such instructions may be given to the Depositary. 

The  Depositary  shall  endeavor,  to  the  extent  practicable,  to  vote  or  cause  to  be  voted  the  amount  of  Class D  shares  represented  by  the  ADSs  in 
accordance with the  written instructions of the  holders  thereof. The  Depositary  will  vote Class D shares,  as to  which no  instructions are received, in 
accordance with the recommendations of the Board of Directors of YPF. The Depositary will not vote Class D shares, as to which no instructions have 
been received, in accordance with the recommendations of the Board of Directors, however, unless YPF has provided to the Depositary an opinion of 
Argentine counsel stating that the action recommended by the Board of Directors is not illegal under Argentine law or contrary to the by-laws or Board 
regulations  of  YPF.  In  addition,  the  Depositary  will,  if  requested  by  the  Board  of  Directors  and  unless  prohibited  by  any  applicable  provision  of 
Argentine law, deposit all Class D shares represented by ADSs for purposes of establishing a quorum at meetings of shareholders, whether or not voting 
instructions with respect to such shares have been received. 

Voting 

Under our by-laws, each Class A, Class B, Class C and Class D share entitles the holder thereof to one vote at any meeting of our shareholders, except 
that the Class A shares (i) vote separately with respect to the election of our Board of Directors and are entitled to appoint one director and one alternate 
director and, (ii) have certain veto rights, as described below. 

Class A Veto Rights 

Under the by-laws, so long as any Class A shares remain outstanding, the affirmative vote of such  shares is required in order to: (i) decide upon the 
merger of the company; (ii) approve any  acquisition of shares by a third party representing more than 50% of the company’s capital; (iii) transfer to 
third parties all the exploitation rights granted to YPF pursuant to the Hydrocarbons Law, applicable regulations thereunder or the Privatization Law, if 
such  transfer  would  result  in  the  total  suspension  of  the  company’s  exploration  and  production  activities;  (iv) voluntarily  dissolve  the  company;  and 
(v) transfer  our  legal  or  fiscal  domicile  outside  Argentina.  The  actions  described  in  clauses  (iii) and  (iv)  above  also  require  prior  approval  of  the 
Argentine Congress through enactment of a law. 

208 

Reporting Requirements 

Pursuant  to  our  by-laws,  any person  who,  directly  or  indirectly,  through  or together  with  its  affiliates  and  persons  acting  in  concert  with  it,  acquires 
Class D shares or securities convertible into Class D shares, so that such person controls more than 3% of the Class D shares, is required to notify the 
Company  of  such  acquisition  within  five  days  of  its  closing,  in  addition  to  complying  with  any  requirements  imposed  by  any  other  authority  in 
Argentina or elsewhere where our Class D shares are traded. Such notice must include the name or names of the person or persons, if any, acting in 
concert with it, the date of the acquisition, the number of shares acquired, the price at which the acquisition was made, and a statement as to whether it is 
the purpose of the person or persons to acquire a greater shareholding in, or control of, us. Each subsequent acquisition by such person or persons, as 
long as it exceeds the above mentioned 3% of the Class D shares, requires a similar notice. 

Certain Provisions Relating to Acquisitions of Shares 

Pursuant to our by-laws: 

•

•

•

•

each acquisition of shares or convertible securities, as a result of which the acquirer, directly or indirectly, through or together with 
its affiliates and persons acting in concert with it (jointly referred to as an “Offeror”), would hold or control shares that, in concert 
with the prior holdings of such Offeror, if any, of shares of such class, would represent: 

15% or more of the outstanding capital stock, or 

20% or more of the outstanding Class D shares; and 

each subsequent acquisition by an Offeror (other than subsequent acquisitions by an Offeror owning or controlling more than 50% 
of our capital prior to such acquisition) (collectively, “Control Acquisitions”), must be carried out in accordance with the procedure 
described under “—Restrictions on Control Acquisitions”. 

In  addition, any merger,  consolidation or  other combination with substantially the  same effect  involving an Offeror that has  previously carried out a 
Control  Acquisition,  or by  any  other person  or  persons, if  such transaction  would  have  for  such  person  or  persons  substantially  the same effect as  a 
Control  Acquisition  (“Related  Party  Share  Acquisition”),  must  be  carried  out  in  accordance  with  the  provisions  described  under  “—Restrictions  on 
Related Party Share Acquisitions” below. The voting, dividend and other distribution rights of any shares acquired in a Control Acquisition or a Related 
Party Share Acquisition carried out other than in accordance with such provisions will be suspended, and such shares will not be counted for purposes of 
determining the existence of a quorum at shareholders’ meetings. 

The Expropriation Law has not triggered these obligations. 

Restrictions on Control Acquisitions 

Prior to consummating any Control Acquisition, an Offeror must obtain the approval of the Class A shares, if any are outstanding, and make a public 
tender offer for all of the outstanding shares and convertible securities of the Company. Such public tender offer shall not be needed for the subsequent 
acquisitions  of  an  Offeror,  who  already  owns  or  controls  shares  that  represent  15%  or  more  of  the  outstanding capital  stock, or  20%  or  more  of  the 
outstanding Class D shares, as long as such Offeror does not own or control, previously or as a consequence of these acquisitions, shares that represent 
more than 50% of the capital stock. For any subsequent acquisition made by an Offeror already owning or controlling more than 50% of the capital 
stock of the Company prior to such acquisition it is neither required to obtain the approval of the Class A shares, nor to make a public tender offer. The 
Offeror will be required to provide the Company with notice of, and certain specified information with respect to, any such tender offer at least fifteen 
business  days  prior  to  the  commencement  of  the  offer,  as  well  as  the  terms  and  conditions  of  any  agreement  with  any  shareholder  proposed  for  the 
Control Acquisition (a “Prior Agreement”). The Company will send each shareholder and holder of convertible securities a copy of such notice at the 
Offeror’s expense. The Offeror is also required to publish a notice containing substantially the same information in a newspaper of general circulation in 
Argentina,  New  York  and  each  other  city  in  which  the  Company’s  securities  are  traded  on  an  exchange  or  other  securities  market,  at  least  once  per 
week, beginning on the date notice is provided to us, until the offer expires. 

209 

Our Board of Directors shall call a special meeting of the holders of Class A shares to be held 10 business days following the receipt of such notice for 
the purpose of considering the tender offer. If the special meeting is not held, or if the shareholders do not approve the tender offer at such meeting, 
neither the tender offer nor the proposed Control Acquisition may be completed. 

The  tender  offer  must  be  carried  out  in  accordance  with  a  procedure  specified  in  our  by-laws  and  in  accordance  with  any  additional  or  stricter 
requirements of jurisdictions, exchanges or markets in which the offer is made or in which our securities of the Company are traded. Under the by-laws, 
the tender offer must provide for the same price for all shares tendered, which price may not be less than the highest of the following (the “Minimum 
Price”): 

(i)

(ii)

(iii)

(iv)

the highest price paid by, or on behalf of, the Offeror for Class D shares or convertible securities during the two years prior to the notice 
provided to the Company, subject to certain antidilution adjustments with respect to Class D shares; 

the highest closing price for the Class D shares on the BASE during the thirty-day period immediately preceding the notice provided to the 
Company, subject to certain antidilution adjustments; 

the price resulting from clause (ii) above multiplied by a fraction, the numerator of which shall be the highest price paid by or on behalf of 
the  Offeror  for  Class D  shares  during  the  two  years  immediately  preceding  the  date  of  the  notice  provided  to  the  Company  and  the 
denominator of which shall be the closing price for the Class D shares on the BASE on the date immediately preceding the first day in such 
two-year  period  on  which  the  Offeror  acquired  any  interest  in  or  right  to  any  Class D  shares,  in  each  case  subject  to  certain  antidilution 
adjustments; and 

the net earnings per Class D share during the four most recent full fiscal quarters immediately preceding the date of the notice provided to 
us, multiplied by the higher of (A) the price/earnings ratio during such period for Class D shares (if any) and (B) the highest price/earnings 
ratio  for  the  Company  in  the  two-year  period  immediately  preceding  the  date  of  the  notice  provided  to  the  Company,  in  each  case 
determined in accordance with standard practices in the financial community. 

Such offer must remain open for a minimum of 20 days and a maximum of 30 days following the provision of notice to the shareholders or publication 
of the offer, and shareholders must have the right to withdraw tendered shares at any time up until the close of the offer. Following the close of such 
tender offer, the Offeror will be obligated to acquire all tendered shares or convertible securities, unless the number of shares tendered is less than the 
minimum, if any, upon which such tender offer was conditioned, in which case the Offeror may withdraw the tender offer. Following the close of the 
tender offer, the Offeror may consummate any Prior Agreement within thirty days following the close of the tender offer; provided, however, that if 
such tender offer was conditioned on the acquisition of a minimum number of shares, the Prior Agreement may be consummated only if such minimum 
was reached. If no Prior Agreement existed, the Offeror may acquire the number of shares indicated in the notice provided to the Company on the terms 
indicated in such notice, to the extent such number of shares were not acquired in the tender offer, provided that any condition relating to a minimum 
number of shares tendered has been met. 

The Expropriation Law has not triggered these obligations. 

Restrictions on Related Party Share Acquisitions 

The  price  per  share  to  be  received  by  each  shareholder  in  any  Related  Party  Share  Acquisition  must  be  the  same  as,  and  must  not  be  less,  than  the 
highest of the following: 

(i)

(ii)

(iii)

the highest price paid by or on behalf of the party seeking to carry out the Related Party Share Acquisition (an “Interested Shareholder”) for 
(A) shares  of  the  class  to  be  transferred  in  the  Related  Party  Share  Acquisition  (the  “Class”)  within  the  two-year  period  immediately 
preceding  the  first  public  announcement  of  the  Related  Party  Share  Acquisition  or  (B) shares  of  the  Class acquired  in  any  Control 
Acquisition, in each case, subject to certain antidilution adjustments; 

the highest  closing sale price of shares of the Class on the BASE  during the thirty days immediately  preceding the announcement of the 
Related  Party  Share  Acquisition  or  the  date  of  any  Control  Acquisition  by  the  Interested  Shareholder,  subject  to  certain  antidilution 
adjustments; 

the price resulting from clause (ii) multiplied by a fraction, the numerator of which shall be the highest price paid by or on behalf of the 
Interested  Shareholder  for  any  share  of  the  Class during  the  two  years  immediately  preceding  the  announcement  of  the  Related  Party 
Transaction and the denominator of which shall be the closing sale price for shares of the Class on the date immediately preceding the first 
day in the two-year period referred to above on which the Interested Shareholder acquired any interest or right in shares of the Class, in each 
case, subject to certain antidilution adjustments; and 

210 

(iv)

the  net  earnings  per  share  of  the  shares  of  the  Class during  the  four  most  recent  full  fiscal  quarters  preceding  the  announcement  of  the 
Related  Party  Transaction  multiplied  by  the  higher  of  the  (A) the  price/earnings  ratio  during  such  period  for  the  shares  of  the  Class and 
(B) the highest price/earnings ratio for the Company in the two-year period preceding the announcement of the Related Party Transaction, in 
each case determined in accordance with standard practices in the financial community. 

In addition, any transaction that would result in the acquisition by any Offeror of ownership or control of more than 50% of our capital stock, or that 
constitutes a merger or consolidation of us, must be approved in advance by the Class A shares while any such shares remain outstanding. 

The Recently amended Capital Markets Law and CNV Regulations:

CNV passed in December 2018 the General Resolution No. 779 which regulates the new regime of tender offers established by Law No. 27,440 which 
amended  the  Capital  Markets  Law  and  was  published  in  May  2018.  Under  this  new  regime,  a  mandatory  tender  offer  at  a  fair  price  (determined 
according to such law) shall be issued by anyone who acting individually or in coordination with others, has effectively obtained a controlling interest of 
a public company, which is deemed to occur: i) directly or indirectly, when obtaining a percentage of votes equal to or higher  than 50% of a public 
company or, ii) when the percentage of votes obtained is below 50% but acts as controller of a public company (i.e. has an interest in the capital stock of 
the company or securities with voting rights that grants the necessary votes to adopt resolutions in ordinary general shareholders meetings or to appoint 
or  revoke  the  majority  of  the  directors  or  members  of  the  Statutory  Auditor´s  Committee).  The  tender  offer  shall  be  made  as  soon  as  possible  after 
closing of the share acquisition but no later than 1 month from such closing. 

Material Contracts 

None. 

Exchange Regulations 

See “Item 3. Key Information—Exchange Regulations” for information on the monetary and currency exchange control restrictions in effect in 

Argentina. 

Taxation 

Argentine Tax Considerations 

The following discussion is a summary of the material Argentine tax considerations relating to the purchase, ownership and disposition of our Class D 
shares or ADSs. 

Dividends tax 

Dividends paid on our Class D shares or ADSs, whether in cash, property or other equity securities, are subject to income tax withholding for dividends 
paid in excess of our taxable accumulated income for the previous fiscal period, at a rate of 35% in respect of such excess. This is a final tax, and it is 
not applicable if dividends are paid in shares rather than in cash. On December 29, 2017, Law No. 27,430 introducing modifications to the income tax 
was published in the Official Gazette, and this “equalization tax” no longer applied to income accrued from January 1, 2018. 

The law also establishes dividend withholding tax rates of 7% for profits accrued during fiscal years starting January 1, 2018 to December 31, 

2019, and 13% for profits accrued in fiscal years starting January 1, 2020 and onwards. 

Personal assets tax 

Argentine individuals and undivided estates, foreign individuals and undivided estates, and foreign entities are subject to personal assets tax of 0.25% of 
the  value  of  any  shares  or  ADSs  issued  by  Argentine  entities,  held  at  December 31  of  each  year.  The  tax  is  levied  on  the  Argentine  issuers  of  such 
shares or ADSs, such as the Company, which must pay this tax in substitution of the relevant shareholders, 

211 

and is based on the equity value (valor patrimonial proporcional), of the shares derived from the latest financial statements at December 31 of each year. 
Pursuant to the Personal Assets Tax Law, we are entitled and expect to seek reimbursement of such paid tax from the applicable shareholders, including 
by foreclosing on the shares, or by withholding dividends. 

On July 22, 2016, Law 27,260 was published  in  the Official Gazette which makes changes to the Argentine tax laws and establishes a new tax debt 
settlement plan and new benefits for compliant taxpayers. According to this law, the Company has applied for an exemption in 2017, for the benefit of 
its shareholders, from this tax. That exemption will apply for fiscal years 2016 to 2018, inclusive. 

Tax on debits and credits in bank accounts 

Tax  on  debits  and  credits  in  bank  accounts  is  levied,  with  certain  exceptions,  for  debits  and  credits  on  checking  accounts  maintained  at  financial 
institutions located in Argentina and other transactions that are used as a substitute for the use of checking accounts. The general tax rate is 0.6% for 
each debit and credit, although in certain cases a decreased rate may apply. The account holder may use up to 34% of the tax paid in respect of credits as 
a credit against other federal taxes. On December 29, 2017, Law No. 27,432 introducing modifications to this credit mechanism was published in the 
Official Gazette. The PEN may fix the tax percentage to be computed as payment on account of the income tax, which will be progressively increased 
by up to 20% per year as of January 1, 2018, and it may also establish that this tax will be fully computed as payment on account of the income tax in 
2022. 

On May 7, 2018 Decree No 409/2018 established that the account holder may use up to 33% of the tax paid in respect of credits and debits as a credit 
against other federal taxes. This rule was applicable as of January 1, 2018. 

Value added tax 

The sale, exchange or other disposition of our Class D shares or ADSs and the distribution of dividends are exempt from the value added tax. 

Stamp taxes 

Stamp taxes may apply in certain Argentine provinces if transfer of our Class D shares or ADSs is performed or executed in such jurisdictions by means 
of written agreements. Transfer of our Class D shares or ADSs is exempt from stamp tax in the City of Buenos Aires. 

Estate and gift tax 

The province of Buenos Aires has imposed a tax on the reception of assets through inheritance or gift, effective January 1, 2011. The tax rates vary from 
1.6026%  to  8.784%,  depending  on  the  value  of  the  transferred  assets  and  the  relationship  between  the  transferor  and  the  transferee.  The  transfer  of 
Class D shares or ADSs among residents of the province of Buenos Aires shall be subject to this tax if other applicable conditions are met. 

Other taxes 

Subject to the discussion above regarding estate and gift taxes in the province of Buenos Aires, there are no Argentine inheritance or succession taxes 
applicable to the ownership, transfer or disposition of our Class D shares or ADSs. In addition, neither the minimum presumed income tax nor any local 
gross turnover tax in the City of Buenos Aires is applicable to the ownership, transfer or disposition of our Class D shares or ADSs. 

In the case of litigation regarding the Class D shares or ADSs before a court of the City of Buenos Aires, a 3% court fee would be charged, calculated on 
the basis of the claim. 

Tax treaties 

Argentina  has  tax  treaties  for  the  avoidance  of  double  taxation  currently  in  force  with  Australia,  Belgium,  Bolivia,  Brazil,  Canada,  Chile,  Denmark, 
Finland, France, Germany, Italy, Mexico, the Netherlands, Norway, Russia, Spain, Sweden, Switzerland, the United 

212 

Kingdom and Uruguay. The tax treaties between Argentina and the United Arab Emirates, Qatar, Turkey, China and Japan have been signed, but the 
treaties have not yet been ratified by their respective governments. There is currently no tax treaty or convention in effect between Argentina and the 
United States. It is not clear when, if ever, a treaty will be ratified or entered into effect. As a result, the Argentine tax consequences described in this 
section  will  apply,  without  modification,  to  a  holder  of  our  Class D  shares  or  ADSs  that  is  a  U.S.  resident.  Foreign  shareholders  located  in  certain 
jurisdictions  with  a  tax  treaty  in  force  with  Argentina  may  be  (i) exempted  from  the  payment  of  the  personal  assets  tax  and  (ii) entitled  to  apply  for 
reduced withholding tax rates on payments to be made by Argentine parties. 

Modifications to the Income Tax Law 

On December 29, 2017, Law No. 27,430 and 27,432 introducing modifications to the Income Tax and other taxes was published in the Official Gazette. 
This summary describes some of the main changes to the corporate income tax and cross-border transaction provisions. On December 27, 2018, this law 
has been regulated by the National Executive Office, by Decrees Nos. 1,170/2018, 279/2018 and 976/2018. 

Income tax 

•

Corporate income tax rate and dividend withholding tax 

The law decreases the corporate income tax rate from 35% to 30% for fiscal years starting January 1, 2018 to December 31, 2019, and to 25% for fiscal 
years starting January 1, 2020 and onwards. The law also establishes a dividend withholding tax and repeals the current “equalization tax”. See section 
“Dividends tax.” 

•

Nonresident’s capital gains tax 

The  new  law  establishes  a  15%  withholding  on  capital  gains  derived  from  the  sale  of  shares  or  other  similar  securities  (calculated  on  the  actual  or 
presumed gains equivalent to 90% of the sale price). The law establishes an exemption applicable to foreign beneficiaries who sell listed shares under 
the  supervision  of  the  CNV.  Furthermore,  an  exemption  is  established  for  the  interest  and  sale  results  of  government  bonds,  NO  and  ADRs.  These 
exemptions will only apply to non-resident foreign beneficiaries do not reside or whose funds do not derive from non-cooperating jurisdictions. Finally, 
such exemptions do not apply to those benefits derived from the securities known as Lebacs. 

In the case of ADRs, the law established that the “source” thereof is given by the residence of the issuer of the respective shares. The law established 
that the income from the purchase-sale of an ADR is of Argentine source if the company that issues the share is Argentine and that it is from a foreign 
source if the issuer is foreign. 

•

Indirect transfers made by nonresidents 

The law establishes a tax on the indirect transfer of assets located in Argentina. In particular, the tax is triggered on the sale or transfer by nonresidents 
of shares or other participations in foreign entities when the following two conditions are met: (i) at least 30% of the value of the foreign entity derives 
from assets located in Argentina; and (ii) the participation being transferred represents (at the moment of the sale or during the 12 prior months) at least 
10% of the equity of the foreign entity. 

The applicable rate is generally 15% (calculated on the actual net gain or a presumed net gain equal to 90% of the sale price), of the proportional value 
that corresponds to the Argentine assets. 

For other Tax Regulations see Note 30.j) to the Audited Consolidated Financial Statements. 

Additionally, on March 21, 2019, the Company’s management informed the Board of Directors of the decision to adhere to the tax revaluation and 
to the payment plan for lawsuits maintained within the Argentine Tax Court as mentioned in Note 30.j. The quantified effects, as of January 1, 2019, are 
detailed below. 

With respect to the tax revaluation, which expired on March 29, 2019 and to which the Company adhered, in relation to the category of “Mines, 
quarries, forests and similar goods”, the regulation establishes the payment of a special tax of 10%, which implies a loss of approximately Ps. 4,600 and 
will allow a greater deduction of the depreciation of the revalued assets on income tax (including its annual revaluation for tax deduction purposes) from 
2018 fiscal period inclusive, and which it also implies the recognition of a gain of approximately Ps. 32,700 as a result of the recognition of the effect of 
such revaluation on deferred tax. 

Additionally,  in  relation  to  the  dispute  with  AFIP  over  the  cost  deduction  for  wells  abandonment  on  income  tax  (see  also  Note  28.b.4),  the 
Company has decided to adhere to the payment plan for the years 2005-2010, for an amount of approximately Ps. 5,500, to be paid on 60 installments, 
plus a variable interest. The loss due to the recording of the liabilities for all the years not prescribed (including the previous mentioned amount) would 
amount to approximately Ps. 18,800. 

The effects resulting from these recently adopted decisions will impact the Company’s financial statements for the first quarter of the year 2019. 

United States Federal Income Tax Considerations 

The following are the material U.S. federal income tax consequences of owning and disposing of our Class D shares or ADSs. This discussion does not 
purport to be a comprehensive description of all the tax considerations that may be relevant to a particular person’s decision to hold such securities. 

213 

This discussion applies only if you are a U.S. Holder (as defined below) and you hold our Class D shares or ADSs as capital assets for U.S. federal 
income tax purposes, and it does not describe all of the tax consequences that may be relevant to holders, subject to special rules, such as: 

•

•

•

•

•

•

•

•

•

•

•

•

certain financial institutions; 

insurance companies; 

dealers and traders in securities or financial instruments, who use a mark-to-market method of tax accounting; 

persons holding Class D shares or ADSs as part of a hedge, “straddle,” wash sale, conversion transaction, integrated transaction or 
similar transaction or persons entering into a constructive sale with respect to the Class D shares or ADSs; 

persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar; 

certain taxpayers who file applicable financial statements required to recognize income for U.S. federal income tax purposes no later 
than when the associated revenue is reflected on such financial statements; 

entities classified as partnerships for U.S. federal income tax purposes; 

persons liable for the alternative minimum tax; 

persons  who  acquired  our  Class D  shares  or  ADSs  pursuant  to  the  exercise  of  an  employee  stock  option  or  otherwise  as 
compensation; 

persons holding Class D shares or ADSs in connection with a trade or business conducted outside of the United States; 

tax-exempt entities, including “individual retirement accounts” or “Roth IRAs”; or 

persons holding Class D shares or ADSs that own or are deemed to own ten percent or more of the total combined vote or value of 
the outstanding shares. 

The discussion does not address non-U.S. federal income taxes like any state, local or foreign taxes, the Medicare tax on net investment income or the 
federal alternative minimum tax. Special rules also apply to individuals, certain of which may not be discussed below. Prospective investors should note 
that  no  rulings  have  been,  or  are  expected  to  be,  sought  from  the  U.S.  Internal  Revenue  Service  (the  “IRS”)  with  respect  to  any  of  the  U.S.  federal 
income tax consequences discussed below, and no assurance can be given that the IRS or a court will not take contrary positions. 

If an entity that is classified as a partnership for U.S. federal income tax purposes holds Class D shares or ADSs, the U.S. federal income tax treatment 
of a partner will generally depend on the status of the partner and upon the activities of the partnership. Partnerships holding Class D shares or ADSs 
and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of holding and disposing of 
the Class D shares or ADSs. 

This discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), administrative pronouncements, judicial decisions and final, 
temporary and proposed Treasury regulations, all as of the date hereof. These laws are subject to change, possibly on a retroactive basis. It is also based 
in part on representations by the Depositary and assumes that each obligation under the deposit agreement and any related agreement will be performed 
in accordance with its terms. 

You are a “U.S. Holder” if you are a beneficial owner of Class D shares or ADSs and are, for U.S. federal income tax purposes: 

•

•

•

a citizen or individual resident of the United States for U.S. federal income tax purposes; 

a  corporation,  or  other  entity  taxable  as  a  corporation,  created  or  organized  in  or  under  the  laws  of  the  United  States,  any  state 
therein or the District of Columbia; or 

an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source. 

In general, if you own ADSs, you will be treated as the owner of the underlying shares represented by those ADSs for U.S. federal income tax purposes. 
Accordingly, no gain or loss will be recognized if you exchange ADSs for the underlying shares represented by those ADSs. 

The U.S. Treasury has expressed concerns that parties to whom American depositary shares are released before the underlying shares are delivered to 
the depositary, or intermediaries in the chain of ownership between U.S. Holders and the issuer of the shares underlying the American depositary shares, 
may be taking actions that are inconsistent with the claiming of foreign tax credits by U.S. holders of American depositary shares. Such actions would 
also be inconsistent with the claiming of the reduced rate of tax, described below, applicable to dividends received by certain non-corporate holders. 
Accordingly, the creditability of Argentine taxes, and the availability of the reduced tax rate for dividends received by certain non-corporate holders, 
each described below, could be affected by actions taken by such parties or intermediaries. 

214 

Please consult your own tax adviser concerning the U.S. federal, state, local and foreign tax consequences of owning and disposing of Class D shares or 
ADSs in your particular circumstances. 

This discussion assumes that YPF is not, and will not become, a passive foreign investment company, as described below. 

Taxation of distributions 

Distributions paid on Class D shares or ADSs, other than certain pro rata distributions of ordinary shares, will be treated as dividends to the extent paid 
out of current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not maintain calculations of 
earnings and profits under U.S. federal income tax principles, it is expected that distributions will generally be reported to U.S. Holders as dividends. 
Subject  to  applicable  limitations  (including  a  minimum  holding  period  requirement),  the  discussion  above  regarding  concerns  expressed  by  the  U.S. 
Treasury  and  the  discussion  below  regarding  passive  foreign  investment  company  rules,  certain  dividends  paid  by  qualified  foreign  corporations  to 
certain non-corporate U.S. Holders that constitute “qualified dividend income” are taxable at a reduced rate. Dividends paid on the Class D shares or 
ADSs generally will be treated as “qualified dividend income” if (i) the Class D shares or ADSs are readily tradable on an established securities market 
in the United States, (ii) the U.S. Holder meets the holding period requirement for the Class D shares or ADSs (generally more than 60 days during the 
121-day period that begins 60 days before the ex-dividend date), and (iii) we were not in the year prior to the year in which the dividend was paid, and 
are  not  in  the  year  in  which  the  dividend  is  paid,  a  passive  foreign  investment  company  (as  defined  below).  A  foreign  corporation  is  treated  as  a 
qualified foreign corporation with respect to dividends paid on stock that is readily tradable on an established securities market in the United States, 
such as the NYSE, where our ADSs are listed. As it relates to certain corporate U.S. Holders, U.S. tax rules may apply to reduce the tax rate on dividend 
income  based  on  the  holders’  ownership  and  minimum  holding  period  in  the  Class D  shares  or  ADSs.  You  should  consult  your  own  tax  adviser  to 
determine whether the favorable rate may apply to dividends you receive in respect of our Class D shares or ADSs and whether you are subject to any 
special rules that limit your ability to be taxed at this favorable rate. The amount of a dividend will include any amounts withheld by us in respect of 
Argentine income taxes. The dividends will be treated as foreign-source dividend income and may, other than as discussed above, not be eligible for the 
dividends-received deduction generally allowed to U.S. corporations under the Code. 

Any dividends paid in Argentine pesos will be included in your income in a U.S. dollar amount calculated by reference to the exchange rate in effect on 
the  date  of  your,  or  in  the  case  of  ADSs,  the  Depositary’s,  receipt  of  the  dividend,  regardless  of  whether  the  payment  is  in  fact  converted  into  U.S. 
dollars. If the dividend is converted into U.S. dollars on the date of receipt, you generally would not recognize foreign currency gain or loss in respect of 
the dividend income. You may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt. Foreign currency 
gain or loss that you recognize will generally be treated as U.S.-source ordinary income or loss. 

Subject  to  generally applicable limitations  that may vary  depending upon  your  circumstances  (including a minimum  holding  period  requirement  and 
limits on credits that may be claimed with respect to qualified dividend income) and, in the case of ADSs, subject to the discussion above regarding 
concerns expressed by the U.S. Treasury, Argentine income taxes, if any, withheld from dividends on Class D shares or ADSs will be creditable against 
your U.S. federal income tax liability. Amounts paid on account of the Argentine personal assets tax may not be eligible for credit against your U.S. 
federal income tax liability. You should consult your tax adviser to determine the tax consequences applicable to you as a result of the payment of the 
Argentine personal assets tax or the withholding of the amount of such tax from distributions, including whether such amounts are includible in income 
or are deductible for U.S. federal income tax purposes. The rules governing the foreign tax credit are complex. You are urged to consult your tax adviser 
regarding the availability of the foreign tax credit under your particular circumstances. 

Sale or other disposition of Class D shares or ADSs 

For U.S. federal income tax purposes, gain or loss you realize on the sale or other disposition of Class D shares or ADSs generally will, subject to the 
discussion below regarding passive foreign investment company rules, be capital gain or loss and will be long-term capital gain or loss if you held the 
Class D shares or ADSs for more than one  year. Certain non-corporate U.S. Holders (including individuals) generally will be subject to U.S. federal 
income tax on long-term capital gain at preferential rates. The amount of your gain or loss will be equal to the difference between the amount realized 
on the disposition and your adjusted tax basis in the relevant Class D shares or ADSs, each as determined in U.S. dollars. The deductibility of capital 
losses is subject to limitations. 

If Argentine income tax is withheld on the sale or other taxable disposition of a Class D share or ADS, the amount realized by a U.S. Holder will include 
the gross amount of the proceeds of the sale or other taxable disposition before deduction of such tax. Capital gain or loss, if any, realized by a U.S. 
Holder on the sale or other taxable disposition of the Class D share or ADS generally will be treated as U.S.-source gain or loss for U.S. foreign tax 
credit purposes. Consequently, in the case of a gain from the disposition of a Class D share or ADS that is subject to Argentine income tax, the U.S. 
Holder may not be able to benefit from the U.S. foreign tax credit for the tax unless the U.S. Holder can apply the credit against U.S. federal income tax 
payable on other income from foreign sources. Alternatively, the U.S. Holder may take a deduction for the Argentine income tax if it does not elect to 
claim a foreign tax credit for any non-U.S. income taxes paid during the taxable year. 

215 

Passive foreign investment company rules 

YPF believes that it was not a “passive foreign investment company” (“PFIC”) for U.S. federal income tax purposes for the taxable year of 2018 and 
does not expect to be a PFIC in the foreseeable future. However, since PFIC status depends upon the composition of a company’s income and assets and 
the market value of its assets from time to time, there can be no assurance that YPF will not be considered a PFIC for any taxable year. If YPF were 
treated as a PFIC for any taxable year during which you held a Class D share or ADS, you generally would be subject to additional filing requirements, 
imputed interest charges and other disadvantageous tax treatment (including the denial of taxation at the lower rates applicable to long-term capital gains 
with  respect to  any gain from  the  sale  or  exchange  of Class D  shares or  ADSs).  Certain  elections  might be  available  that would result  in  alternative 
treatments  (such  as  mark-to-market  treatment).  U.S.  Holders  should  consult  their  tax  advisers  to  determine  whether  any  of  these  elections  would  be 
available and, if so, what the consequences of the alternative treatments would be in their particular circumstances. 

In  addition,  if  YPF  were  to  be  treated  as  a  PFIC  in  a  taxable  year  in  which  it  paid  a  dividend  or  the  prior  taxable  year,  the  reduced  dividend  rate 
discussed above with respect to dividends paid by qualified foreign corporations to certain non-corporate holders would not apply. 

Information reporting and backup withholding 

Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are 
subject  to  information  reporting  and  may  be  subject  to  backup  withholding  unless  (i) you  are  an  exempt  recipient  or  (ii) in  the  case  of  backup 
withholding, you provide a correct taxpayer identification number and certify that you are not subject to backup withholding. 

The amount of any backup withholding from a payment to you will be allowed as a credit against your U.S. federal income tax liability and may entitle 
you to a refund, provided that the required information is timely furnished to the IRS. 

Certain U.S. Holders may be required, generally on IRS Form 8938, to report information relating to their ownership of securities of a non-U.S. person, 
subject to certain exceptions (including an exception for stock held in certain accounts maintained by a U.S. financial institution, such as our ADSs). A 
U.S.  Holder  who  fails  to  timely  furnish  the  required  information  may  be  subject  to  a  penalty.  U.S.  Holders  are  urged  to  consult  their  tax  advisers 
regarding the effect, if any, of these rules on their ownership and disposition of Class D shares or ADSs. 

Documents on Display 

YPF is subject to the information requirements of the U.S. Securities Exchange Act (the “Exchange Act”), except that as a foreign issuer, YPF is 
not subject to the proxy rules or the short-swing profit disclosure rules of the Exchange Act. In accordance with these statutory requirements, YPF files 
or furnishes reports and other information with the SEC. Reports and other information filed or furnished by YPF with the SEC may be inspected and 
copied at the public reference facilities maintained by the SEC at 100 F Street, N. E., Washington, D.C. 20549. Copies of such material may be obtained 
by mail from the Public Reference Section of the SEC at 100 F Street, N.E., Washington, D.C. 20549, at prescribed rates. You may obtain information 
on  the  operation  of  the  Public  Reference  Section  by  calling  the  SEC  at  +1-800-732-0330.  All  of  the  SEC  filings  made  electronically  by  YPF  are 
available to the public on the SEC’s website at http://www.sec.gov. 

ITEM 11.

Quantitative and Qualitative Disclosures about Market Risk 

The following quantitative and qualitative information is provided about financial instruments to which we are a party as of December 31, 2018, 
and from which we may derive gains or incur losses from changes in market, interest rates, foreign exchange rates or commodity prices. We do not enter 
into derivative or other financial instruments for trading purposes. 

This discussion contains forward-looking statements that are subject to risks and uncertainties. Actual results could vary materially as a result of a 

number of factors including those set forth in “Item 3. Key Information—Risk Factors.” 

Foreign currency exposure 

The value of financial assets and liabilities denominated in a currency different from the Company’s functional currency is subject to variations 
resulting from fluctuations in exchange rates. Since YPF’s functional currency is the U.S. dollar, the currency that generates the greatest exposure is the 
Argentine peso, the Argentine legal currency. See Note 2.b.1 to the Audited Consolidated Financial Statements. 

216 

In addition, our costs and receipts denominated in currencies other than the Argentine peso, including the U.S. dollar, often do not match. We 
generally  follow  a  policy  of  not  hedging  our  debt  obligations  in  U.S.  dollars.  See  “Item  3.  Key  Information—Risk  Factors—Risks  Relating  to 
Argentina—We may be exposed to fluctuations in foreign exchange rates.” 

Additionally, YPF is enabled to operate as settlement agent in the Rosario Futures Market (“ROFEX”). 

The annual rate of devaluation of the Argentine peso was approximately 101.4% considering the period-end exchange rates for U.S. dollars as of 
December 31,  2018  and  2017.  See  “Item  5.  Operating  and  Financial  Review  and  Prospects—Factors  Affecting  Our  Operations—Macroeconomic 
conditions” for additional information. The main effects of a devaluation of the Argentine Peso on our net profit are those related to the accounting of 
deferred income tax related mainly to fixed assets, which we expect would have a negative effect; current income tax which we expect would have a 
positive effect; increased depreciation and amortization resulting from the remeasurement in pesos of our fixed and intangible assets; and exchange rate 
differences as a result of our exposure to the peso, which we expect would have a positive effect due to the fact that our functional currency is the U.S. 
dollar. See “Item 3. Key Information—Risk Factors—Risks Relating to Argentina—We may be exposed to fluctuations in foreign exchange rates.” 

As  mentioned  in  Note  2.b.1  to  Audited  Consolidated  Financial  Statements,  the  Company  has  determined  that  the  U.S.  dollar  is  its  functional 
currency. Therefore, the effect of changes in the dollar exchange rate on dollar currency positions have no impact on the exchange difference recorded 
in the consolidated statements of comprehensive income included in the Audited Consolidated Financial Statements, but affect the amount of our assets 
and liabilities remeasured in pesos as a consequence of devaluation and considering our reporting currency (pesos). For additional information about our 
assets  and  liabilities  denominated  in  currencies  other  than  pesos  (principally  U.S.  dollars)  see  Note  33  to  our  Audited  Consolidated  Financial 
Statements. 

Interest rate exposure 

The table below provides information about our assets and liabilities as of December 31, 2018 that may be sensitive to changes in interest rates. 
See “Item 3. Key Information—Risk Factors—Risks Relating to Argentina—Variations in interest rates and exchange rate on our current and/or future 
financing arrangements may result in significant increases in our borrowing costs”. See additionally, Note 4 and Note 16 to the Audited Consolidated 
Financial Statements.

Crude oil and other hydrocarbon product price exposure 

Our results of operations are also exposed to volatility mainly in the prices of certain oil products, especially in connection with imports. Although 
we have occasionally contracted financial derivatives in the past with the aim of decreasing exposure to these commodities price risks, as of the date of 
this annual report YPF was not a party to any commodity hedging instruments in connection with crude oil and other hydrocarbon product prices. For 
information  on  our  hydrocarbons  delivery  commitments  as  of  December 31,  2018,  see  “Item  4.  Information  on  the  Company—Upstream—Delivery 
commitments.” 

ITEM 12.

Description of Securities Other than Equity Securities 

American Depositary Shares 

Our ADSs are listed on the NYSE under the symbol “YPF.” The Bank of New York Mellon is the Depositary. Each ADS represents the right to 

receive one share. 

The  Depositary  collects  its  fees  for  delivery  and  surrender  of  ADSs  directly  from  investors  depositing  shares  or  surrendering  ADSs  for  the 
purpose of withdrawal or from intermediaries acting for them. The Depositary collects fees for making distributions to investors by deducting those fees 
from the amounts distributed or by selling a portion of distributable property to pay the fees. The Depositary may collect its annual fee for depositary 
services by deductions from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for 
them. The Depositary may generally refuse to provide fee-attracting services until its fees for those services are paid. 

The table below sets forth the fees payable, either directly or indirectly, by a holder of ADSs as of the date of this annual report. 

Persons depositing or withdrawing shares must pay:
U.S.$5.00 (or less) per 100 ADSs (or portion of 100 ADSs)

Cancellation of ADSs for the purpose of withdrawal

A fee equivalent to the fee that would be payable if securities distributed to a 
holder  had  been  shares  and  the  shares  had  been  deposited  for  issuance  of 
ADSs

Transfer fees, as may from time to time be in effect

Expenses of the depositary

For:
Issuance of ADRs (including, without limitation, issuance pursuant to a 
stock dividend or stock split declared by YPF, an exchange of stock or 
a distribution of rights) and surrender of ADRs

Sale, on behalf of the holder, of rights to subscribe for additional shares 
or any right of any nature distributed by YPF

Transfer and registration of shares on YPF share register to or from the 
name  of  the  depositary  or  its  agent  when  a  holder  deposits  or 
withdraws shares

Cable,  telex  and  facsimile  transmission  expenses,  as  provided  in  the 
deposit agreement

Expenses  incurred  by  the  depositary  in  the  conversion  of  foreign 
currency (1)

Taxes and other governmental charges the depositary or the custodian have to 
pay  on  any  ADS  or  share  underlying  an  ADS,  for  example,  stock  transfer 
taxes, stamp duty or withholding taxes

As necessary

(1)

Pursuant to our deposit agreement, whenever the depositary shall receive foreign currency, as a cash dividend or other distribution which, in the 
judgment  of  the  depositary,  can  be  converted  on  a  reasonable  basis  into  U.S.  dollars  and  transferred  to  the  United  States,  it  will  convert  such 
foreign currency into U.S. dollars and transfer the resulting U.S. dollars (after deduction of its customary charges and expenses in effecting such 
conversion) to the United States.

Controls and Procedures 

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures 

As of December 31, 2018, YPF, under the supervision and with the participation of YPF’s management, including our current Principal Executive 
Officer  and  Principal  Financial  Officer,  performed  an  evaluation  of  the  effectiveness  of  the  design  and  operation  of  our  disclosure  controls  and 
procedures  (as  defined  in  Rule  13a-15(e)  or  Rule  15d-15(e)  under  the  Exchange  Act).  There  are,  as  described  below,  inherent  limitations  to  the 
effectiveness of any control system, including disclosure controls and procedures. Accordingly, even effective disclosure controls and procedures can 
provide only reasonable assurance of achieving their control objectives. 

Based  on  this  evaluation,  the  Chief  Executive  Officer  and  the  Controller  concluded  that  there  was  reasonable  assurance  that  the  design  and 
operation of these disclosure controls and procedures were effective as of December 31, 2018, in ensuring that information required to be disclosed in 
reports  that  the  company  files  under  the  Exchange  Act  is  (1) recorded,  processed,  summarized  and  reported  within  the  time  periods  specified  in  the 
SEC’s rules and forms, and (2) accumulated and communicated to our management, including our Principal Executive Officer and Principal Financial 
Officer, as appropriate to allow timely decisions regarding required disclosure. 

Management’s Report on Internal Control Over Financial Reporting 

Management  of  YPF  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting  (as  defined  in  Rule 
13a-15(f) under the Exchange Act). YPF’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS and includes those policies 
and procedures that: 

•

•

•

Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of 
YPF; 

Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with 
IFRS, and that our receipts and expenditures are being made only in accordance with authorizations of YPF’s management and directors; 
and 

Provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use  or  disposition  of  our  assets  that 
could have a material effect on the financial statements. 

Because of its inherent limitations, any system of internal control over financial reporting, no matter how well designed, may not prevent or detect 
misstatements, due to the possibility that a control can be circumvented or overridden or that misstatements due to error or fraud may occur that are not 
detected. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of 
changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

219 

Under the supervision and with the participation of YPF’s management, including our current Principal Executive Officer and Principal Financial 
Officer,  we  conducted  an  evaluation  of  the  effectiveness  of  our  internal  control  over  financial  reporting  using  the  criteria  established  in  “Internal 
Control-Integrated  Framework  (2013)”  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (“the  COSO  criteria”). 
Based on this assessment, our management concluded that, our internal control over financial reporting was effective as of December 31, 2018. 

Our internal control over financial reporting as of December 31, 2018 has been audited by Deloitte & Co. S.A., an independent registered public 

accounting firm, as stated in their report included in the F-pages of this annual report.

CONSOLIDATED FINANCIAL STATEMENTS 
AS OF DECEMBER 31, 2018, 2017 and 2016 

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and shareholders of YPF SOCIEDAD ANONIMA 

Opinions on the Financial Statements and Internal Control over Financial Reporting 

We have audited the accompanying consolidated statements of financial position of YPF SOCIEDAD ANONIMA (an Argentine Corporation) and its 
controlled  companies  (the  “Company”)  as  of  December 31,  2018,  2017,  and  2016,  the  related  consolidated  statements  of  comprehensive  income, 
changes in shareholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2018, and the related notes (collectively 
referred to as the “financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2018, based 
on  criteria  established  in  Internal  Control  —  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission (COSO). 

In  our  opinion,  the  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  as  of 
December 31, 2018, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 
2018, in conformity with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). 
Also,  in  our  opinion,  the  Company  maintained,  in  all  material  respects,  effective  internal  control  over  financial  reporting  as  of  December 31,  2018, 
based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. 

Basis for Opinions 

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its 
assessment  of  the  effectiveness  of  internal  control  over  financial  reporting,  included  in  the  accompanying  Management’s  Report  on  Internal  Control 
over Financial Reporting (Item 15). Our responsibility is to express an opinion on these financial statements and an opinion on the Company’s internal 
control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board 
(United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We  conducted  our  audits  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and  perform  the  audits  to  obtain 
reasonable  assurance  about  whether  the  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud,  and  whether  effective 
internal control over financial reporting was maintained in all material respects. 

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether 
due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the 
amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made 
by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included 
obtaining an understanding of internal control over financial reporting, assessing the risk that 

a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits 
also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis 
for our opinions. 

Definition and Limitations of Internal Control over Financial Reporting 

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable  assurance  regarding  the  reliability  of  financial 
reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s 
internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, 
accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the  company;  (2) provide  reasonable  assurance  that  transactions  are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (3) provide 
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a 
material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation 
of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of 
compliance with the policies or procedures may deteriorate.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS 

2.a) Basis of preparation 

Application of IFRS 

The consolidated financial statements of the Group for the year ended December 31, 2018 are presented in accordance with IFRS as issued by IASB and 
interpretations issued by the IFRIC. 

Moreover, some additional issues required by the LGS and/or CNV’s regulations have been included. 

The amounts and other information corresponding to the years ended on December 31, 2017 and 2016 are an integral part of the consolidated financial 
statements mentioned above and are intended to be read only in relation to these financial statements. 

These consolidated financial statements were approved by the Board of Directors’ meeting and authorized to be issued on March 7, 2019. 

Current and Noncurrent classification 

The  presentation  in  the  statement  of  financial  position  makes  a  distinction  between  current  and  noncurrent  assets  and  liabilities,  according  to  the 
activities operating cycle. Current assets and liabilities include assets and liabilities, which are realized or settled within the 12-month period from the 
end of the fiscal year. 

All other assets and liabilities are classified as noncurrent. Current and deferred tax assets and liabilities (payable income tax) are presented separately 
from each other and from other assets and liabilities, as current and noncurrent, as applicable. 

Fiscal year-end 

The Company’s fiscal year begins on January 1 and ends on December 31, each year. 

Accounting criteria 

The consolidated financial statements have been prepared under historical cost criteria, except for financial assets measured at fair value through profit 
or loss and share-based compensation, which were measured at fair value. 

Non-monetary assets and liabilities of subsidiaries having the Peso as functional currency, were adjusted for inflation. See Note 2.b.1.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2018, 2017 AND 2016

2.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

Use of estimates 

The preparation of financial statements at a certain date requires the Management to make estimates and assessments affecting the amount of assets and 
liabilities recorded, contingent assets and liabilities disclosed at such date, as well as income and expenses recorded during the period. Future results 
might differ from the estimates and assessments made on the date of preparation of these consolidated financial statements. 

The description of  any significant  estimates and  accounting judgments made by Management in applying the  accounting policies, as well as the key 
estimates and areas with greater degree of complexity which require more critical judgments, are disclosed in Note 2.c. 

Consolidation policies 

For purposes of presenting the consolidated financial statements, the full consolidation method was used with respect to all subsidiaries, which are those 
companies which the Group controls. The Group controls an entity when it is exposed, or is entitled to the variable results arising from its equity interest 
in the entity, and has the ability to affect those results through its power over the entity. This capacity is, in general but not solely, obtained by the direct 
or indirect ownership of more than 50% of the voting shares of a company. 

Interest  in  JO  and  other  agreements  which  gives  the  Group  a  contractually-established  percentage  over  the  rights  of  the  assets  and  obligations  that 
emerge  from  the  contract,  have  been  consolidated  line  by  line  on  the  basis  of  the  mentioned  participation  over  the  assets,  liabilities,  income  and 
expenses related to each contract. Assets, liabilities, income and expenses of JO are presented in the consolidated statement financial position and in the 
consolidated statement of comprehensive income, in accordance with their respective nature. 

Note 9 details the fully consolidated controlled subsidiaries. Furthermore, Note 24 details the main JO, proportionally consolidated. 

In the consolidation process, balances, transactions and profits between consolidated companies and JO have been eliminated. 

The  Company’s  consolidated  financial  statements  are  based  on  the  most  recent  available  financial  statements  of  the  companies  which  YPF  controls, 
taking into consideration, where applicable, significant subsequent events and transactions, information available to the Company’s management and 
transactions between YPF and such subsidiaries, which could have produced changes to their shareholders’ equity. The date of the financial statements 
of  such  subsidiaries  used  in  the  consolidation  process  may  differ  from  the  date  of  YPF’s  financial  statements  due  to  administrative  reasons.  The 
accounting principles and procedures used by subsidiaries have been homogenized, where appropriate, with those used by YPF in order to present the 
consolidated  financial  statements  based  on  uniform  accounting  and  presentation  policies.  The  financial  statements  of  subsidiaries  whose  functional 
currency is different from the presentation currency are translated using the procedure set out in Note 2.b.1. 

The  Group  holds  100%  of  capital  of  the  consolidated  companies,  with  the  exception  of  the  holdings  in  Metrogas  and  YTEC.  The  Group  takes  into 
account quantitative and qualitative aspects to determine which subsidiaries have significant non-controlling interests. In accordance with the previously 
mentioned, there are no material non-controlling interests to be disclosed, as required by IFRS 12 “Disclosure of Interests in Other Entities”. 

Financial information of subsidiaries, associates and joint ventures in hyperinflationary economies 

Under IAS 29 “Financial Reporting in Hyperinflationary Economies” the financial statements of an entity whose functional currency is the currency of a 
hyperinflationary economy shall be stated in terms of the measuring unit current at the end of the reporting period. The standard sets forth quantitative 
and qualitative factors to be contemplated in order to determine whether or not an economy is hyperinflationary. In recent years, inflation in Argentina 
has  been  high,  with  an  accumulated  inflation  rate  exceeding  100%  over  the  last  three  years.  In  addition,  certain  recent  qualitative  and  quantitative 
factors, such as the significant devaluation of the Peso, lead to the conclusion that the restatement by inflation of annual or interim financial statements

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2018, 2017 AND 2016

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

Companies could not present their restated financial statements because Decree No. 664/03 of the PEN prohibited regulatory agencies (including the 
CNV) from receiving financial statements adjusted for inflation. 

Law  No. 27,468,  published  on  December 4,  2018  in  the  Official  Gazette  repealed  Decree  No. 1,269/02  of  the  PEN  as  amended  (including  the 
aforementioned Decree No. 664/03 of the PEN). The provisions of the aforementioned law became in full force and effect as of December 28, 2018, the 
date  of  the  publication  of  the  CNV  General  Resolution  No. 777/18,  which  established  that  annual  financial  statements,  interim  and  special  periods 
closing  from  December 31,  2018  inclusive,  must  be  submitted  adjusted  for  inflation,  as  established  by  IAS  29.  The  FACPCE’s  guidelines  will  be 
applied to those issues not specifically addressed in the aforementioned regulations. 

Although the application of IAS 29 does not directly affect YPF because its functional currency is the U.S. dollar as mentioned in section b) of this 
Note, it does affect the investments that the Company has in its subsidiaries, associates and joint ventures whose functional currency is the Peso, all of 
which have restated their financial statements. 

In compliance with IAS 29 guidelines, the adjustment was based on the last date on which subsidiaries, associates and joint ventures whose functional 
currency is the Peso restated their financial statements to reflect the effects of inflation. For this purpose, in general terms, the inflation from the date of 
acquisition or addition, or from the date of asset revaluation, as applicable, was computed in balances of non-monetary assets and liabilities. As a result 
of the adjustment for inflation in such financial statements, the value of non-monetary items increased, with the cap of their recoverable value, and with 
the consequent effect on deferred tax. Regarding income statement, in addition to the restatement of revenues, costs, expenses and other items, the net 
monetary position effect was included in a separate item in the Other financial results. 

In accordance with the above, the application of IAS 29 generated an increase in equity, net income and other comprehensive income for the fiscal year 
of the Company. 

2.b) Significant Accounting Policies 

2.b.1) Functional and reporting currency and tax effect on Other comprehensive income 

Functional currency 

YPF, based on parameters set out in IAS 21 “The effects of change in foreign exchange rates”, has defined the U.S. dollar as its functional currency. 
Consequently,  non-monetary  cost-based  measured  assets  and  liabilities,  as  well  as  income  or  expenses,  are  remeasured  into  functional  currency  by 
applying the exchange rate prevailing at the date of the transaction. 

Transactions in currencies other than the functional currency of the Company are deemed to be “foreign currency transactions” and are remeasured into 
functional currency by applying the exchange rate prevailing at the date of the transaction (or, for practical reasons and when exchange rates do not 
fluctuate significantly, the average exchange rate for each month). At the end of each year or at the time of payment, the balances of monetary assets and 
liabilities in currencies other than the functional currency are measured at the exchange rate prevailing at such date and the exchange differences arising 
from  such  measurement  are  recognized  as  “Net  financial  results”  in  the  consolidated  statement  of  comprehensive  income  for  the  year  in  which  they 
arise. 

Assets,  liabilities  and  results  of  subsidiaries,  associates  and  joint  ventures  are  shown  in  their  respective  functional  currencies.  The  effects  of  the 
conversion  into  U.S.  dollars  of  the  financial  information  of  those  companies  whose  functional  currency  is  other  than  the  U.S.  dollar  are  recorded  as 
“Other comprehensive income” in the Consolidated Statement of Comprehensive Income.

Presentation currency 

According to CNV Resolution No. 562, the Company must present its financial statements in pesos. Therefore, the financial statements prepared in the 
Company’s functional currency are translated into the presentation currency, as per the following procedures: 

•

•

•

Assets and liabilities of each of the balance sheets presented are translated using the exchange rate on the balance sheet closing date; 

Items  of  the  consolidated  statement  of  comprehensive  income  are  translated  using  the  exchange  rate  at  the  time  the  transactions  were 
generated (or, for  practical reasons, and provided the  exchange  rate  has not changed  significantly, using  each month’s average exchange 
rate); 

All  translation  differences  resulting  from  the  foregoing  are  recognized  under  “Other  Comprehensive  Income”  in  the  statement  of 
comprehensive income. 

Effects  of  the  translation  of  investments  in  subsidiaries,  associates  and  joint  ventures  with  the  Peso  as  functional  currency  corresponding  to  a 
hyperinflationary economy 

Under IAS 21, the financial statements of a subsidiary with the functional currency of a hyperinflationary economy are to be restated according to IAS 
29  before  they  are  included  in  the  consolidated  financial  statements  of  its  parent  company  with  a  functional  currency  of  a  non-hyperinflationary 
economy, except for their comparative figures. 

Following the aforementioned guidelines, the results and financial position of subsidiaries with the Peso as functional currency were translated into U.S 
dollars by the following procedures: all amounts (i.e., assets, liabilities, stockholders’ equity items, expenditures and revenues) were translated at the 
exchange rate effective at the closing date of the financial statements, except for comparative amounts, which were presented as current amounts in the 
financial  statements  of  the  previous  fiscal  year  (i.e.,  these  amounts  were  not  be  adjusted  to  reflect  subsequent  variations  in  price  levels  or  exchange 
rates). Thus, the effect of the restatement of comparative amounts was recognized in other comprehensive income. 

These criteria were also implemented by the Group for its investments in associates and joint ventures. 

When  an  economy  ceases  to  be  hyperinflationary  and  an  entity  ceases  to  restate  its  financial  statements  in  accordance  with  IAS  29,  it  will  use  the 
amounts restated according to the price level of the date on which the entity ceased to make such restatement as historical costs, in order to translate 
them into the presentation currency. 

Tax effect on Other Comprehensive Income 

Results  included  in  Other  Comprehensive  Income  in  connection  with  translation  differences  generated  by  investments  in  subsidiaries,  associates  and 
joint  ventures  whose  functional  currency  is  other  than  U.S.  dollar  as  well  as  conversion  differences  arising  from  the  translation  of  YPF’s  financial 
statements  into  its  presentation  currency  (Pesos),  have  no  effect  on  the  income  tax  or  in  the  deferred  tax  since  at  the  time  they  were  generated,  the 
relevant transactions did not make any impact on net income or taxable income. 

2.b.2) Financial Assets 

Classification 

In accordance with IFRS 9 “Financial instruments”, the Group classifies its financial assets into two categories: 

•

Financial assets at amortized cost 

Financial assets are measured at amortized cost if both of the following criteria are met: (i) the objective of the Group’s business model is to hold 
the assets to collect the contractual cash flow, and (ii) the contractual terms only require specific dates for payment of principal and interest.

AS OF DECEMBER 31, 2018, 2017 AND 2016

2.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

In addition, and for assets that meet the above conditions, IFRS 9 contemplates the option of designating, at the time of the initial recognition, an 
asset as measured at its fair value, if doing so would eliminate or significantly reduce the valuation or recognition inconsistency that could arise in 
the event that the valuation of the assets and liabilities or the recognition of profit or losses resulting therefrom be carried out on different bases. 
The Group has not designated a financial asset at fair value by using this option. 

As of the closing date of these consolidated financial statements, the Group’s financial assets at amortized cost include certain elements of cash 
and cash equivalents, trade receivables and other receivables. 

•

Financial assets at fair value through profit or loss 

If either of the two criteria above are not met, the financial asset is classified as an asset measured “at fair value through profit or loss”. 

As of the closing date of these consolidated financial statements, the Group’s financial assets at fair value through profit or loss include mutual 
funds and public securities. 

Recognition and measurement 

Purchases  and  sales  of  financial  assets  are  recognized  on  the  date  on  which  the  Group  commits  to  purchase  or  sell  the  assets.  Financial  assets  are 
recognized when the rights to receive cash flows from the investments and the risks and rewards of ownership have expired or have been transferred. 

Financial assets at amortized cost are initially recognized at fair value plus transaction costs. These assets accrue interest based on the effective interest 
rate method. 

Financial assets at their fair value through profit or loss are initially recognized at fair value and transaction costs are recognized as an expense in the 
statement of comprehensive income. They are subsequently valued at fair value. Changes in fair values and results from sales of financial assets at fair 
value through profit or loss are recorded in “Net financial results” in the statement of comprehensive income. 

In general, the Group uses the transaction price to ascertain the fair value of a financial instrument on initial recognition. In other cases, the Group 
records a gain or loss on initial recognition only if the fair value of the financial instrument can be supported by other comparable and observable market 
transactions for the same type of instrument or if it is based in a technical valuation that only inputs observable market information. Unrecognized gains 
or losses on initial recognition of a financial asset are recognized later on, only to the extent they arise from a change in the factors (including time) that 
market participants would consider upon setting the price. 

Gains/losses on debt instruments measured at amortized cost and not included for hedging purposes are charged to income when the financial assets are 
derecognized or an impairment loss is recognized and during the amortization process using the effective interest rate method. The Group reclassifies all 
investments on debt instruments only when its business model for managing those assets changes. 

Impairment of financial assets 

The Group assesses the impairment of its financial assets according to the expected credit losses model. The impairment methodology applied depends 
on whether there has been a significant increase in credit risk. 

For  trade  receivables,  the  Group  applies  the  simplified  approach  allowed  by  IFRS  9,  which  requires  expected  lifetime  losses  to  be  recognized  from 
initial recognition of the receivables. See Note 2.b.18. 

Offsetting financial instruments 

Financial assets and liabilities are offset when there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a 
net basis, or realize the asset and settle the liability simultaneously.

2.b.3) Inventories 

Inventories are valued at the lower value between their cost and their net realizable value. Cost includes acquisition costs (less trade discount, rebates 
and other similar items), transformation and other costs, which have been incurred when bringing the inventory to its present location and condition. The 
net realizable value is the estimated selling price in the ordinary course of business less selling expenses. 

In the case of refined products, costs are allocated in proportion to the selling price of the related products (isomargen method) due to the difficulty for 
distributing the production costs to each product. Raw materials, packaging and other inventory are valued at their acquisition cost. 

The Group assesses the net realizable value of the inventories at the end of each year and recognizes in profit or loss in the consolidated statement of 
comprehensive  income  the  appropriate  valuation  adjustment  if  the  inventories  are  overstated.  When  the  circumstances  that  previously  caused 
impairment  no  longer  exist  or  when  there  is  clear  evidence  of  an  increase  in  the  inventories’  net  realizable  value  because  of  changes  in  economic 
circumstances, the amount of a write-down is reversed. 

2.b.4) Intangible assets 

The Group initially recognizes intangible assets at their acquisition or development cost. This cost is amortized on a straight-line basis over the useful 
lives of these assets. At the end of each year, such assets are measured at their acquisition or development cost, considering the criteria adopted by the 
Group in the transition to IFRS, less any accumulated amortization and any accumulated impairment losses. 

The main intangible assets of the Group are as follows: 

i.

Service concessions arrangements 

Includes transportation and storage concessions. These assets are valued at their acquisition cost, considering the criteria adopted by the Group in 
the transition to IFRS, net of accumulated amortization. They are depreciated using the straight-line method during the course of the concession 
period. 

The Argentine Hydrocarbons Law allows the executive branch of the Argentine government to award 35-year concessions for the transportation 
of  oil,  gas  and  petroleum  products  following  submission  of  competitive  bids.  The  term  of  a  transportation  concession  may  be  extended  for  an 
additional  ten-year  term.  Pursuant  to  Law  No. 26,197,  provincial  governments  have  the  same  powers.  Holders  of  production  concessions  are 
entitled to receive a transportation concession for the oil, gas and petroleum products that they produce. The holder of a transportation concession 
has the right to: 

•

•

Transport oil, gas and petroleum products; 

Build and operate oil, gas and products pipelines, storage facilities, pump stations, compressor plants, roads, railways and other facilities 
and equipment necessary for the efficient operation of a pipeline system. 

In  addition,  a  transportation  concession  holder  is  under  an  obligation  to  transport  hydrocarbons  to  third  parties,  without  discrimination,  in 
exchange  for  a  tariff.  This  obligation,  however,  is  applicable  to  oil  or  gas  producers  only  to  the  extent  the  concession  holder  has  available 
additional  capacity,  and  is  expressly  subject  to  the  transportation  requirements  of  the  concession  holder.  Transportation  tariffs  are  subject  to 
approval by the Federal Energy Secretariat for oil and petroleum derivatives pipelines, and by ENARGAS, for gas pipelines. Upon expiration of a 
transportation concession, oil pipelines and related facilities revert to the Argentine Government, without any payment to the concession holder.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

In connection with the foregoing, the Privatization Law granted the Company 35-year transportation concessions for the transportation facilities 
operated by Yacimientos Petrolíferos Fiscales S.E. as of such date. The main pipelines related to said transportation concessions are the following: 

•

•

La Plata / Dock Sud 

Puerto Rosales / La Plata 

• Monte Cristo / San Lorenzo 

•

•

Puesto Hernández / Luján de Cuyo 

Luján de Cuyo / Villa Mercedes 

Thus,  assets  meeting  certain  requirements  set  forth  by  the  IFRIC  12,  which  the  Company  Management’s  judgment  are  met  in  the  facilities 
mentioned in the preceding paragraphs, are recognized as intangible assets. 

ii.

Exploration rights 

The Group classifies exploration rights as intangible assets, which are valued at their cost, considering the criteria adopted by the Group in the 
transition to IFRS, net of the related impairment, if applicable. 

Investments related to unproved oil reserves or fields under evaluation are not depreciated. These investments are reviewed for impairment at least 
once a year, or whenever there are indicators that the assets may have become impaired. Any impairment loss or reversal is recognized in profit or 
loss in the consolidated statement of comprehensive income. Exploration costs (geological and geophysical expenditures, expenditures associated 
with the maintenance of unproved reserves and other expenditures relating to exploration activities), excluding exploratory well drilling costs, are 
charged to expense in the consolidated statement of comprehensive income as incurred. 

iii. Other intangible assets 

In this section, it mainly includes costs relating to computer software development expenditures, as well as assets that represent the rights to use 
technology and knowledge (“know how”) for the manufacture and commercial exploitation of equipment related to oil extraction. These items are 
valued  at  their  acquisition  cost,  considering  the  criteria  adopted  by  the  Group  in  the  transition  to  IFRS,  net  of  the  related  depreciation  and 
impairment, if applicable. 

These assets are amortized on a straight-line basis over their useful lives, which range between 3 and 14 years. The Group reviews annually the 
mentioned estimated useful life. 

The Group has no intangible assets with indefinite useful lives as of December 31, 2018, 2017 and 2016. 

2.b.5) Investments in associates and joint ventures 

Investments in associates and joint ventures are valued using the equity method. 

According to this method, the investment is initially recognized at cost under “Investments in associates and joint ventures” in the statement of financial 
position, and the book value increases or decreases to recognize the investor’s interest in the income of the associate or joint venture after the acquisition 
date, which is reflected in the statement of comprehensive income under “Income from equity interest in associates and joint ventures”. The investment 
includes, if applicable, the goodwill identified in the acquisition. 

Associates are considered those in which the Group has significant influence, understood as the power to participate in the financial and operating policy 
decisions  of  the  investee  but  does  not  have  control  or  joint  control  over  those  policies.  Significant  influence  is  presumed  in  companies  in  which  a 
company has an interest of 20% or more and less than 50%.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

Joint arrangements are contractual agreements through which the Group and the other party or parties have joint control. Under the provisions of IFRS 
11,  “Joint  arrangements”,  and  IAS  28,  “Investments  in  Associates  and  Joint  Ventures”,  investments  in  which  two  or  more  parties  have  joint  control 
(defined  as a  “joint  arrangement”) will  be  classified as  either  a joint  operation  (when  the parties  that  have joint  control have rights to the  assets and 
obligations for the liabilities relating to the joint arrangement) or a joint venture (when the parties that have joint control have rights to the net assets of 
the  joint  arrangement).  Considering  such  classification,  joint  operations  will  be  proportionally  consolidated  and  joint  ventures  will  be  accounted  for 
under the equity method. 

Associates and joint ventures have been valued based upon the latest available financial statements of these companies as of the end of each year, taking 
into consideration, if applicable, significant subsequent events and transactions, available management information and transactions between the Group 
and  the  related  company,  which  have  produced  changes  on  the  latter’s  shareholders’  equity.  The  dates  of  the  financial  statements  of  such  related 
companies  used  in  the  consolidation  process  may  differ  from  the  date  of  the  Company’s  financial  statements  due  to  administrative  reasons.  The 
accounting principles and procedures used by associates and joint ventures have been homogenized, where appropriate, with those used by the Group in 
order to present the consolidated financial statements based on uniform accounting and presentation policies. The financial statements of associates and 
joint ventures whose functional currency is different from the presentation currency are translated using the procedure set out in Note 2.b.1. 

Investments in companies in which the Group has no significant influence or joint control, are valued at cost. 

Investments in companies with negative shareholders’ equity are disclosed in the “Other Liabilities” account. 

On each closing date or upon the existence of signs of impairment, it is determined whether there is any objective evidence of impairment in the value of 
the  investment  in  associates  and  joint  ventures.  If  this  is  the  case,  the  Group  calculates  the  amount  of  the  impairment  as  the  difference  between  the 
recoverable value of associates and joint ventures and their book value, and recognizes the difference under “Income from equity interest in associates 
and joint ventures” in the statement of comprehensive income. The recorded value of investments in associates and joint ventures does not exceed their 
recoverable value. 

Note 9 details the investments in associates and joint ventures. 

2.b.6) Property, plant and equipment 

General criteria 

Property, plant and equipment are valued at their acquisition cost, plus all the costs directly related to the location of such assets for their intended use, 
considering the deemed cost criteria adopted by the Group in the transition to IFRS. 

Borrowing costs of assets that require a substantial period to be ready for their intended use are capitalized as part of the cost of these assets. 

Major inspections, necessary to restore the service capacity of the related asset are capitalized and depreciated on a straight-line basis over the period 
until the next overhaul is scheduled. 

The costs of renewals, betterments and enhancements that extend the useful life of properties and/or improve their service capacity are capitalized. As 
property, plant and equipment are retired, the related cost and accumulated depreciation are derecognized. 

Repair, conservation and ordinary maintenance expenses are recognized in the statement of comprehensive income as incurred. 

These assets are reviewed for impairment at least once a year, or whenever there are indicators that the assets may have become impaired, as detailed in 
Note 2.b.8.

Depreciation 

Property,  plant  and  equipment,  other  than  those  related  to  oil  and  gas  exploration  and  production  activities,  are  depreciated  using  the  straight-line 
method, over the years of estimated useful life of the assets, as follows: 

Buildings and other constructions
Refinery equipment and petrochemical plants
Infrastructure of natural gas distribution
Transportation equipment
Furniture, fixtures and installations
Selling equipment
Electric power generation facilities
Other property

Land is classified separately from the buildings or facilities that may be located on it and is deemed to have an indefinite useful life. Therefore, it is not 
depreciated. 

The Group reviews annually the estimated useful life of each class of assets. 

Oil and gas exploration and production activities 

The Group recognizes oil and gas exploration and production transactions using the “successful-efforts” method. The costs incurred in the acquisition of 
new  interests  in  areas  with  proved  and  unproved  reserves  are  capitalized  as  incurred  under  Mineral  properties,  wells  and  related  equipment.  Costs 
related to exploration permits are classified as intangible assets. 

Exploration costs, excluding the costs associated with exploratory wells, are charged to expense as incurred. Costs of drilling exploratory wells, 
including stratigraphic test wells, are capitalized pending determination as to whether the wells have found proved reserves that justify commercial 
development. If such reserves are not found, the mentioned costs are charged to expense. Occasionally, an exploratory well may be determined to have 
found oil and gas reserves, but classification of those reserves as proved cannot be made. In those cases, the cost of drilling the exploratory well will 
continue to be capitalized if the well has found a sufficient quantity of reserves to justify its completion as a producing well, and the Group is making 
sufficient progress assessing the reserves as well as the economic and operating viability of the project. If any of the mentioned conditions are not met, 
the cost of drilling exploratory wells is charged to expense. In addition, the exploratory activity involves, in many cases, the drilling of multiple wells 
through several years in order to completely evaluate a project. As a consequence, some exploratory wells may be kept in evaluation for long periods, 
pending the completion of additional wells and exploratory activities needed to evaluate and quantify the reserves related to each project. The detail of 
the exploratory well costs in evaluation stage is described in Note 8. 

Drilling costs applicable to productive wells and to developmental dry holes, as well as tangible equipment costs related to the development of oil and 
gas reserves, have been capitalized. 

The capitalized costs described above are depreciated as follows: 

a)

b)

The capitalized costs related to productive activities have been depreciated by field on a unit-of-production basis by applying the ratio of produced 
oil and gas to estimate proved, developed oil, and gas reserves. 

The capitalized costs related to the acquisition of property and the extension of concessions with proved reserves have been depreciated by field 
on a unit-of-production basis by applying the ratio of produced oil and gas to the estimated proved oil and gas reserves. 

Revisions in estimates of crude oil and gas proved reserves are considered prospectively in the calculation of depreciation. Revisions in estimates of 
reserves are performed at least once a year. Additionally, estimates of reserves are audited by external independent petroleum engineers on a three-year 
rotation plan.

Costs related to hydrocarbon well abandonment obligations 

Costs related to hydrocarbon well abandonment obligations are capitalized at their discounted value along with the related assets, and are depreciated 
using  the  unit-of-production  method.  As  compensation,  a  liability  is  recognized  for  this  concept  at  the  estimated  value  of  the  discounted  payable 
amounts.  Revisions  of  the  payable  amounts  are  performed  upon  consideration  of  the  current  costs  incurred  in  abandonment  obligations  considering 
internal and external available information. Due to the number of wells in operation and/or not abandoned and as well as the complexity with respect to 
different geographic areas where the wells are located, current costs incurred in plugging activities, weighted by the complexity level of the wells, are 
used for estimating the plugging activities costs of the wells pending abandonment. Current costs incurred are the best source of information in order to 
make the best estimate of asset retirement obligations. Future changes in the costs mentioned above, the useful life of the wells and their estimate of 
abandonment,  as  well  as  changes  in  regulations  related  to  abandonment,  which  are  not  possible  to  be  predicted  at  the  date  of  issuance  of  these 
consolidated  financial  statements,  could  affect  the  value  of  the  abandonment  obligations  and,  consequently,  the  related  asset,  affecting  the  results  of 
future operations. Such changes are recognized pursuant to IFRIC 1. 

Environmental property, plant and equipment 

The Group capitalizes the costs incurred in limiting, neutralizing or preventing environmental pollution only in those cases where at least one of the 
following conditions is met: (a) the expenditure improves the safety or efficiency of an operating plant (or other productive assets); (b) the expenditure 
prevents or limits environmental pollution at operating facilities; or (c) the expenditure is incurred to prepare assets for sale and does not raise the assets’ 
carrying value above their estimated recoverable value. 

The environmental  related property,  plant and  equipment and  the  corresponding accumulated  depreciation  are  disclosed  in  the  consolidated  financial 
statements  together  with  the  other  elements  that  are  part  of  the  corresponding  property,  plant  and  equipment  which  are  classified  according  to  their 
accounting nature. 

2.b.7) Provisions and contingent liabilities 

The Group makes a distinction between: 

i.

Provisions 

Represent legal or assumed obligations arising from past events, the settlement of which is expected to give rise to an outflow of resources and 
which amount and timing are uncertain. Provisions are recognized when the liability or obligation-giving rise to an indemnity or payment arises, 
to the extent that its amount can be reliably estimated and that the obligation to settle is probable or certain. Provisions include both obligations 
whose  occurrence  does  not  depend  on  future  events  (such  as  provisions  for  environmental  liabilities  and  provision  for  hydrocarbon  wells 
abandonment obligations); as well as obligations that are probable and can be reasonably estimated whose realization depends on the occurrence 
of future events that are out of the control of the Group (such as provisions for contingencies). The amount recorded as provision corresponds to 
the best estimate of expenditures required to settle the obligation, taking into consideration the relevant risks and uncertainties. See Note 14. 

ii.

Contingent liabilities 

Represent possible obligations that arise from past events and whose existence will be confirmed only by the occurrence or non-occurrence of one 
or more future events not wholly within the control of the Group, or present obligations arising from past events, the amount of which cannot be 
estimated  reliably  or  whose  settlement  is  not  likely  to  give  rise  to  an  outflow  of  resources  embodying  future  economic  benefits.  Contingent 
liabilities are not recognized in the consolidated financial statements, but rather are disclosed to the extent they are significant, as required by IAS 
37, “Provisions, contingent liabilities and contingent assets”. See Note 28. 

When a contract qualifies as onerous, the related unavoidable liabilities are recognized in the consolidated financial statements as provisions, net of the 
expected benefits.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2018, 2017 AND 2016

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

Except for provisions for hydrocarbon wells abandonment obligations, where the timing of settlement is estimated on the basis of the work plan of the 
Group,  and  considering  the  estimated  production  of  each  field  (and  therefore  its  abandonment),  in  relation  to  other  noncurrent  provisions,  it  is  not 
possible to reasonably estimate a specific schedule of settlement of the provisions considering the characteristics of the concepts included. 

In relation to certain provisions and contingent liabilities, the Group, in accordance with the established exemption contemplated in IAS 37, has decided 
not to set forth certain critical information that could seriously impair it in the claims made by third parties. 

2.b.8) Impairment of property, plant and equipment and intangible assets 

To  evaluate  the  impairment  of  property,  plant  and  equipment  and  intangible  assets,  the  Group  compares  their  carrying  value  with  their  recoverable 
amount at the end of each year, or more frequently, if there are indicators that the carrying value of an asset may not be recoverable. 

In order to assess impairment, assets are grouped into CGU, whereas the assets do not generate cash flows that are independent of those generated by 
other assets or CGU, considering regulatory, economic, operational and commercial conditions. Considering the above mentioned, the Group’s assets 
were grouped into nine CGU, which are described below: 

i.

Upstream Segment 

The assets included in this segment have been grouped into four CGU: one of them groups the assets of YPF fields with crude oil reserves, and 
three of them group the assets of fields with natural gas reserves, according to Argentina’s basins. 

•

•

•

•

CGU Oil; 

CGU Gas – Neuquina Basin; 

CGU Gas – Noroeste Basin; 

CGU Gas – Austral Basin; 

As of December 31, 2016, there were the Gas CGU—Neuquina Basin—YSUR and CGU Gas—Austral Basin—YSUR, which after the operative 
merger of the YSUR Group with YPF, were incorporated to the CGU Gas—Neuquina Basin and CGU Gas—Austral Basin, both of YPF. 

ii.

Gas and Power Segment 

The  assets  of  this  segment  have  been  grouped  into  three  CGU:  CGU  Gas  and  Power  YPF,  which  mainly  includes  the  commercialization  and 
regasification of natural gas; CGU Metrogas, which includes assets related to natural gas distribution activities; and CGU YPF EE, which includes 
the assets related to the generation and commercialization of electric energy. In connection with CGU YPF EE, see Notes 3 and 5. 

iii. Downstream Segment 

The assets of this segment have been grouped in the CGU Downstream YPF, which mainly comprises the assets involved in crude oil refining (or 
supplementing that activity), the petrochemical industry and the marketing of such products. 

iv.

Central Administration and Others 

It includes the CGU AESA, which primarily comprises the assets used for construction purposes related to the activities of the subsidiary.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

This aggregation is the best reflection of how the Group currently makes its assets management decisions for the generation of independent cash flows. 

The recoverable amount is the higher of the fair value less costs of disposal and the value in use. In assessing the value in use, the estimated future cash 
flows are discounted to their present value using a rate that reflects the weighted average cost of capital employed for the Group. 

If  the  recoverable  amount  of  a  CGU  is  estimated  to  be  less  than  its  carrying  amount,  the  carrying  amount  of  the  CGU  is  reduced  to  its  recoverable 
amount, and an impairment loss is recognized in the consolidated statement of comprehensive income. 

Any impairment loss is allocated to the assets comprising the CGU on a pro-rata basis based on their carrying amount. Consequently, the basis for future 
depreciation or amortization will take into account the reduction in the value of the asset as a result of any accumulated impairment losses. 

Upon  the  occurrence  of  new  events  or  changes  in  existing  circumstances,  which  prove  that  an  impairment  loss  previously  recognized  could  have 
disappeared  or  decreased,  a  new  estimate  of  the  recoverable  amount  of  the  corresponding  asset  is  calculated  to  determine  whether  a  reversal  of  the 
impairment losses recognized in previous periods needs to be made. See Note 2.c. 

In  the  event  of  a  reversal,  the  carrying  amount  of  the  asset  (or  the  CGU)  is  increased  to  the  revised  estimate  of  its  recoverable  amount  so  that  the 
increased carrying amount does not exceed the carrying amount that would have been determined in case no impairment loss had been recognized for 
the asset (or the CGU) in the past. 

2.b.9) Methodology used in the estimation of recoverable amounts 

The methodology used to estimate the recoverable amount of property, plant and equipment and intangible assets consists of using the higher of: i) the 
calculation of the value in use, based on expected future cash flows from the use of such assets, discounted at a rate that reflects the weighted average 
cost of capital, and, if available, ii) the price that would be received in a regular transaction between market participants to sell the asset as of the date of 
these consolidated financial statements, less the disposal costs of such assets. 

In the assessment of the value in use, cash flow forecasts based on the best estimate of income and expense available for each CGU using sector inputs, 
past results and future expectations of business evolution and market development are utilized. The most sensitive aspects included in the cash flows 
used in all the CGU are the purchase and sale prices of hydrocarbons (including applicable gas distribution fees), outstanding regulations, estimates of 
cost increases, personnel costs and investments. 

The cash flows from Upstream assets are generally projected for a period that covers the economically productive useful lives of the oil and gas fields 
and  is  limited  by  the  contractual  expiration  of  the  concession  permits,  agreements  or  exploitation  contracts.  The  estimated  cash  flows  are  based  on 
production  levels,  commodity  prices  and  estimates  of  the  future  investments  that  will  be  necessary  in  relation  to  undeveloped  oil  and  gas  reserves, 
production costs, field decline rates, market supply and demand, contractual conditions and other factors. The unproved reserves are weighted with risk 
factors, based on the type of each one of the Upstream assets. 

Downstream and Gas and Power cash flows are estimated on the basis of projected sales trends, contribution margins by unit, fixed costs and investment 
flows,  in  line  with  the  expectations  regarding  the  specific  strategic  plans  of  each  business.  However,  cash  inflows  and  outflows  relating  to  planned 
restructurings  or  productivity  enhancements  are  not  considered.  The  projections’  evaluation  horizon  is  10  years,  considering  annual  rent  for  the  last 
period, based on the long useful life of these CGU assets. 

The  reference  prices  considered  are  based  on  a  combination  of  market  prices  available  in  those  markets  where  the  Group  operates,  also  taking  into 
consideration specific circumstances that could affect different products the Group commercializes and management’s estimations and judgments.

2.b.10) Employee benefit plans and share-based payments 

i.

Retirement plan 

Effective March 1, 1995, the Group has established a defined contribution retirement plan that provides benefits for each employee who elects to 
join the plan. Each plan member will pay an amount between 3% and 10% of his monthly compensation, and the Group will pay an amount equal 
to that contributed by each member. 

The plan members will receive from the Group the contributed funds before retirement only in the  case of voluntary termination under certain 
circumstances or dismissal without cause and, additionally, in case of death or incapacity. The Group has the right to discontinue this plan at any 
time, without incurring termination costs. 

ii.

Performance Bonus Programs 

These  programs  cover  certain  of  the  Group’s  personnel.  These  bonuses  are  based  on  compliance  with  corporate  business  unit  objectives  and 
performance. They are calculated considering the annual compensation of each employee, certain key factors related to the fulfillment of these 
objectives and the performance of each employee, and are paid in cash. 

iii.

Share-based benefit plan 

From the year 2013, YPF has decided to implement a share-based benefit plan. This plan, organized in annual programs, covers certain executive 
and management positions and key personnel or personnel with critical technical knowledge. The above-mentioned plan is aimed at aligning the 
performance of these personnel with the objectives of the strategic plan of the Company. 

This plan consists in giving participation, through shares of the Company, to each selected employee with the condition of remaining in it for the 
previously defined period (up to three years from the grant date, hereinafter “service period”), being this the only condition necessary to access the 
agreed final retribution. 

For accounting purposes, YPF recognizes the effects of the plans in accordance with the guidelines of IFRS 2, “Share-based Payment”. In this 
order, the total cost of the plans granted is measured at the grant date, using the fair value or market price of the Company’s share in the United 
States market. The above-mentioned cost is accrued in the Company’s net income for the year, over the vesting period, with the corresponding 
increase in Shareholders’ equity in the “Share-based Benefit Plans” account. 

2.b.11) Revenue recognition 

Revenue from ordinary activities arising from contracts entered into with customers 

In compliance with IFRS 15, the Group has classified the main contracts with customers, as follows: 

•

•

•

•

•

Contracts for the sale of fuel in consignment; 

Contracts for the direct sale of fuel; 

Contracts for the sale of natural gas; 

Contracts and agreements for the sale of other refined products; 

Construction contracts. 

In the first four types of contracts, related to the sale of goods, income is recognized when the control of the goods is transferred to the customer. Even 
in  the  case  of  consignment  contracts,  revenue  is  not  recognized  until  the  good  is  sold  to  the  intermediary’s  customer.  It  is  emphasized  that  in  these 
contracts there are no performance obligations that are separate or different from the delivery of goods.

AS OF DECEMBER 31, 2018, 2017 AND 2016

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

In the case of the construction contracts, revenue is recognized considering the estimated final margin for each project that arises from technical studies 
on sales and the estimated total costs of each of them, as well as their physical progress. In this type of contracts, performance obligations are satisfied 
over time. 

As  mentioned  in  Note  2.b.26,  as  IFRS  15  became  effective,  the  Group  has  adopted  the  full  retrospective  approach  for  the  implementation  of  this 
standard, which has not affected the accounting policies related to the recognition of revenues from contracts with customers for the years ended 2017 
and 2016. 

In compliance with IAS 18, in fiscal years 2017 and 2016, revenue was recognized on sales of crude oil, refined products and natural gas, in each case, 
when title and risks were transferred to the customer following the conditions described below: 

•

•

•

•

•

The Group has transferred to the buyer the significant risks and rewards of ownership of the goods. 

The Group does not retain neither continuing managerial involvement to the degree usually associated with ownership nor effective control 
over the goods sold. 

The amount of revenue can be measured reliably. 

It is probable that the economic benefits associated with the transaction will flow to the Group. 

The costs incurred or to be incurred in respect of the transaction can be measured reliably. 

In compliance with IAS 11, in fiscal years 2017 and 2016, revenues and costs related to construction activities performed by AESA are accounted for in 
the consolidated statement of comprehensive income for the year using the percentage of completion method, considering the final contribution margin 
estimated for each project at the date of issuance of the financial statements, which arises from technical studies on sales and total estimated costs for 
each of them, as well as their physical progress. The adjustments in contract values, changes in estimated costs and anticipated losses on contracts in 
progress are reflected in earnings in the year when they become evident. 

Revenue recognition related to Government incentive programs 

The  following  are  the  main  revenues  that  fall  within  the  scope  of  the  IAS  20  “Accounting  for  Government  grants  and  disclosure  of  government 
assistance”: 

•

Incentives  for  the  Additional  Injection  of  Natural  Gas  Stimulus  Program  and  benefits  from  the  Stimulus  Program  for  Investments  in  the 
Natural Gas Production Development from Unconventional Reservoirs 

Granted by the former Planning and Strategic Coordination Commission of the National Plan of Hydrocarbons Investment by Resolutions 
No. 1/2013  and  No. 14/2015  and  by  the  MINEM  by  Resolution  46-E/2017,  respectively  (see  Note  30.g),  they  constitute  economic 
compensation for the companies committed to increase their respective production. These incentives have been included in “Revenues” in 
the consolidated statement of comprehensive income. 

•

Compensation for providing gas oil to public transport of passengers at a differential price 

Economic  compensations  to  hydrocarbon  producing  and  refining  companies  committed  to  ensure  the  supply  of  gasoil  in  the  necessary 
volumes  to  meet  domestic  needs.  These  incentives  have  been  included  in  “Revenues”  in  the  consolidated  statement  of  comprehensive 
income. 

•

Procedure to compensate for the lower income that Natural Gas Piping Distribution Service Licensed Companies receive from their users 

Compensations received as a result of (i) the application of benefits and/or discounts to users under the regulations in force regarding tariffs 
of  the  natural  gas  distribution  service  through  networks  and  (ii) the  higher  costs  of  UNG  with  respect  to  those  established  for  their 
recognition in tariffs. These incentives have been included in “Revenues” in the consolidated statement of comprehensive income.

•

Payment of the daily differences accumulated on a monthly basis between the price of gas purchased by Distributors and the natural gas 
price included in the tariff schemes effective from April 1, 2018 to March 31, 2019 

Under  Decree  No. 1053/18,  the  Argentine  Government  assumed  the  payment  of  the  differences  exclusively  arising  from  exchange  rate 
variations and corresponding to natural gas volumes delivered in such term. These incentives have been included as reversals in “Costs” in 
the consolidated statement of comprehensive income. 

•

Temporary economic assistance to Metrogas 

Enacted by the MINEM under Resolution No. 312-E/2016 and by the former Argentine Energy Secretariat under Resolution No. 263/2015 
(see Note 30.h), its purpose was to fund the expenses and investments related to the normal operation of the natural gas distribution service 
through networks, while preserving the chain of payment to natural gas producers until the Tariff Review was concluded. The incentives 
were included in the item “Other net operating results” in the consolidated statement of comprehensive income. 

•

Incentive for investment in capital goods, computers and telecommunications for domestic manufacturers 

It takes place through a fiscal bond, provided that manufacturers have industrial establishments located in Argentina, a requirement that is 
satisfied by the controlled company AESA. The Group recognizes such incentive when the formal requirements established by Decrees of 
the PEN No. 379/2001, No. 1551/2001, its amendments and regulations are satisfied, to the extent that there is reasonable certainty that the 
grants  will  be  received.  The  bond  received  may  be  computed  as  a  tax  credit  for  the  payment  of  national  taxes  (i.e.,  income  tax,  tax  on 
minimum presumed income, value added tax and domestic taxes) and may be transferred to third parties only one time. The incentives have 
been included in the item “Other net operating results” in the consolidated statement of comprehensive income. 

Recognition  of  these  incomes  are  made  at  their  fair  value  when  there  is  a  reasonable  certainty  that  incentives  will  be  received  and  that  regulatory 
requirements related therewith have been fulfilled. 

2.b.12) Leases 

The Group’s leases are classified as operating or financial leases, taking into account the economic substance of the contracts. 

The Group as a lessee: 

•

Operating leases 

A lease is classified as an operating lease when the lessor does not transfer substantially to the lessee the entire risks and rewards incidental to 
ownership of the asset. 

Costs related to operating leases are recognized on a straight-line basis in “Rental of real estate and equipment” and “Operation services and other 
service contracts” of the consolidated statement of comprehensive income for the year in which they arise. 

•

Financial Leases 

Leases are classified as financial when the lessor transfers to the lessee substantially all the risks and benefits inherent in the leased property. 

The Group has no significant financial leases as they are defined by current IFRS regulations. 

The Group does not own significant assets leased to third parties. 

See also Note 2.b.26 regarding the initial application of IFRS 16 “Leases” on January 1, 2019.

2.b.13) Net income per share 

Net income per share is calculated by dividing the net income for the year attributable to YPF’s shareholders by the weighted average of shares of YPF 
outstanding during the year net of repurchased shares as mentioned in Note 25. 

Diluted  net  income  per  share  is  calculated  by  dividing  the  net  income  for  the  fiscal  year  by  the  weighted  average  of  shares  outstanding,  and  when 
dilutive, adjusted for the effect of all potentially dilutive shares, including share options, on an as if they had been converted. 

In computing diluted net income per share, income available to ordinary shareholders, used in the basic earnings per share calculation, is adjusted by 
those results that would result of the potential conversion into ordinary stock. The weighted average number of ordinary shares outstanding is adjusted 
to include the number of additional ordinary shares that would have been outstanding if the dilutive potential ordinary shares had been issued. Diluted 
net income per share is based on the most advantageous conversion rate or exercise price over the entire term of the instrument from the standpoint of 
the security holder. The calculation of diluted net income per share excludes potential ordinary shares if their effect is anti-dilutive. 

As of the date of the issuance of these consolidated financial statements, there are no YPF instruments outstanding that imply the existence of potential 
ordinary shares (taking into account the Company’s intent to cancel the share-based benefit plans through their repurchase in the market), thus the basic 
net income per share matches the diluted net income per share. See Note 26. 

2.b.14) Financial liabilities 

Financial liabilities are initially recognized at their fair value less the transaction costs incurred. Because the Group does not have financial liabilities 
whose  characteristics  require  the  recognition  at  their  fair  value,  according  to  IFRS,  after  their  initial  recognition,  financial  liabilities  are  measured  at 
amortized  cost.  Any  difference  between  the  financing  received  (net  of  transaction  costs)  and  the  repayment  value  is  recognized  in  the  consolidated 
statement of comprehensive income over the life of the related debt instrument, using the effective interest rate method. 

The  Group  eliminates  a  financial  liability  (or  a  part  thereof)  from  its  statement  of  financial  position  when  it  has  been  extinguished,  i.e.,  when  the 
obligation specified in the corresponding contract has been paid or canceled, or has expired. 

The  Group  will  account  for  a  swap  of  financial  instruments  with  substantially  different  conditions  by  eliminating  the  original  financial  liability  and 
registering a new financial liability. Similarly, the Group will account for a substantial change in the current conditions of an existing financial liability 
or part of it as a cancellation of the original financial liability and the recognition of a new financial liability. 

At the closing of these consolidated financial statements, the Group’s financial liabilities at amortized cost include accounts payable, other liabilities, 
loans and liabilities associated with assets held for disposal. 

2.b.15) Taxes, withholdings and royalties 

Income tax and tax on minimum presumed income 

The Group recognizes income tax applying the deferred tax method, which considers the effect of temporary differences between the carrying amount of 
an asset or a liability and its tax base and the tax loss carryforwards and other tax credits, which may be used to offset future taxable income, at the 
statutory rate then in force, at the time of its use or reversion. 

Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary 
differences can be utilized.

Tax expense for the year includes current and deferred income tax. Income tax is recognized in the consolidated statement of net income, except to the 
extent  that  it  relates  to  items  recognized  in  other  comprehensive  income  or  directly  in  equity,  in  which  case,  the  tax  is  also  recognized  in  other 
comprehensive income or directly in equity, respectively. 

Tax  expense  is  calculated  on  the  basis  of  the  tax  laws  enacted  or  substantially  enacted  at  the  date  of  the  fiscal  year  end,  in  the  countries  where  the 
Company  and  its  subsidiaries  operate  and  generate  taxable  income.  The  Group  periodically  evaluates  positions  taken  in  tax  returns  with  respect  to 
situations in which applicable tax regulation is subject to interpretation. The Group establishes provisions where appropriate on the basis of amounts 
expected to be paid to the tax authorities. 

According to the amendments introduced by the Argentine Tax Reform Law No. 27,430 published in the Official Gazette on December 29, 2017 (see 
Note 30.j), the general tax rate is reduced from 35% for fiscal years 2016 y 2017 to 30% for fiscal years 2018 and 2019 and to 25% from year 2020. 
Accordingly, although the gradual changes of the income tax rate are not applicable to the measurement of the current tax, the main accounting impact 
of the new regulations occurs in the measurement of deferred assets and tax liabilities. See Note 15. 

Additionally, upon the determination of taxable profit on minimum presumed income is calculated by applying the current 1% tax rate to taxable assets 
as of the end of each year. This tax supplements income tax. The tax liability will coincide with the higher of the determination of tax on minimum 
presumed income and the Group’s tax liability related to income tax, calculated applying the current income tax rate to taxable income for the year. 
However, if the tax on minimum presumed income exceeds income tax during one tax year, such excess may be computed as prepayment of any income 
tax excess over the tax on minimum presumed income that may be generated in the next ten years. It is worth mentioning that it was overruled for the 
years beginning on January 1, 2019, as established by Law No. 27,260. 

Personal assets tax – Substitute responsible 

Individuals and foreign entities, as well as their undistributed estates, regardless of whether they are domiciled or located in Argentina or abroad, are 
subject to personal assets tax of 0.25% of the value of any shares or ADSs issued by Argentine entities, held at December 31 of each year. The tax is 
levied on the Argentine issuers of such shares or ADSs, such as YPF, which must pay this tax in substitution of the relevant shareholders, and is based 
on the equity value (following the equity method), or the book value of the shares derived from the latest financial statements at December 31 of each 
year. Pursuant to the Personal Assets Tax Law, the Group is entitled to seek reimbursement of such paid tax from the applicable shareholders, using the 
method  the  Group  considers  appropriate.  However,  according  to  Law  27,260  YPF  has  requested  the  exemption  of  this  tax  (for  the  benefit  of  its 
shareholders). This exemption applied to fiscal periods 2016 to 2018. 

Royalties and withholding systems for hydrocarbon exports 

A 12% (or 15%, if applicable) royalty is payable on the value at the wellhead of crude oil production and the commercialized natural gas volumes, on 
the wellhead value of such products, which is similar to the final sales price less transportation and storage costs. 

Pursuant to the extension of the original terms of exploitation concessions, the Group has agreed to pay an extraordinary production royalty and in some 
cases a royalty of 10% is payable over the production of unconventional hydrocarbons (see Note 30.a). 

Royalty expense and extraordinary production royalties are accounted for as a production cost. 

Besides, the Group is subject to the withholding regimes for hydrocarbon exports outlined in Note 30.d.

or regulations. 

Subscribed capital stock and adjustments to contributions 

Consists of the shareholders’ contributions represented by shares and includes the outstanding shares at face value net of treasury shares mentioned in 
the following paragraph “Treasury shares and adjustment to treasury shares”. The subscribed capital account has remained at its historical value and the 
adjustment required previous Argentine GAAP (Generally Accepted Accounting Principles) to state this account in constant Pesos is disclosed in the 
“Adjustments to contributions” account. 

The adjustment to contributions cannot be distributed in cash or in kind, but is allowed its capitalization by issuing shares. In addition, this item may be 
used to compensate for accumulated losses. 

Treasury shares and adjustments to treasury shares 

Corresponds to the reclassification of the nominal value and the corresponding adjustment for inflation (Adjustment to Contributions) of shares issued 
and repurchased by YPF in market transactions, as is required by the CNVs regulations in force. 

Share-based benefit plans 

Corresponds to the balance related to the share-based benefit plans as mentioned in Note 2.b.10.iii. 

Acquisition cost of repurchased shares 

Corresponds to the cost incurred in the acquisition of the shares that YPF holds as treasury shares. Additionally, see Note 25. 

Considering CNV regulations RG 562, the balance of this account restricts the distribution of retained earnings. 

Share trading premium 

Corresponds to the difference between accrued amount in relation to the share-based benefit plans and acquisition cost of the shares settled during the 
year in relation with the mentioned plans. 

Considering the debit balance of the premium, distribution of retained earnings is restricted by the balance of this premium. 

Issuance premiums 

Corresponds to the difference between the amount of subscription of the capital increase and the corresponding face value of the shares issued. 

Legal reserve 

In accordance with the provisions of LGS, YPF has to appropriate to the legal reserve no less than 5% of the algebraic sum of net income, prior year 
adjustments,  and  transfers  from  other  comprehensive  income  to  retained  earnings  and  accumulated  losses  from  previous  years,  until  such  reserve 
reaches 20% of the subscribed capital plus adjustment to contributions. As of December 31, 2018, the legal reserve has been fully integrated, amounting 
to 2,007. 

Reserve for future dividends 

Corresponds to the allocation made by the YPF’s Shareholders’ meeting, whereby a specific amount is transferred to the reserve for future dividends.

accordance  with  the  General  Resolution  No. 609  of  the  CNV.  Such  reserve  was  disaffected  for  absorption  of  negative  balance  on  the  “Retained 
earnings” in the fiscal year ended December 31, 2017, according the aforementioned Resolution. 

Other comprehensive income 

Includes income and expenses recognized directly in equity accounts and the transfer of such items from equity accounts to the income statement of the 
year or to retained earnings, as defined by IFRS. 

Retained earnings 

Includes accumulated gains or losses without a specific appropriation that being positive can be distributed upon the decision of the Shareholders’ 
meeting, while not subject to legal restrictions. Additionally, it includes the net income of previous years that was not distributed, the amounts 
transferred from other comprehensive income and adjustments to income of previous years produced by the application of accounting standards. 

Additionally, pursuant to the regulations of the CNV, when the net balance of other comprehensive income account is positive, it will not be distributed 
or capitalized nor used to compensate accumulated losses, and when the net balance of these results at the end of a year is negative, a restriction on the 
distribution of retained earnings for the same amount will be imposed. 

Non-controlling interest 

Corresponds to the interest in the net assets of Metrogas (30%) and YTEC (49%), representing the rights on shares that are not owned by YPF. 

2.b.17) Derivative financial instruments and hedge transactions 

Derivative financial instruments are recognized at fair value. The method of recognizing the resulting gain or loss depends on whether the derivative is 
designated as a hedge instrument, and, if so, the nature of the item being hedged. 

The  Group  manages  exposures  to  several  risks  using  different  financial  instruments.  The  Group  does  not  use  derivative  financial  instruments  for 
speculative purposes. 

The Group’s policy is to apply hedge accounting to hedging relationships where it is both permissible and practical under IFRS 9, and its application 
reduces volatility. Transactions that may be effective hedges in economic terms may not always qualify for hedge accounting under IFRS 9. 

•

•

•

During the fiscal year ended December 31, 2018, the Group only used derivative financial instruments traded on active markets (futures contracts 
in U.S. dollars) and has not applied hedge accounting. 

During the fiscal year ended as of December 31, 2017, the Group did not used derivative financial instruments. 

During the fiscal year ended December 31, 2016, the Group only used derivative financial instruments traded on active markets (futures contracts 
in U.S. dollars) and has not applied hedge accounting. 

Gains or losses from these derivative financial instruments are classified as “Other financial results”, in the statement of comprehensive income.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2018, 2017 AND 2016

2.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

Fair values of derivative financial instruments that are traded in active markets are computed by reference to market prices. The fair value of derivative 
financial instruments that are not traded in an active market is determined using valuation techniques. The Group uses its judgment to select a variety of 
methods and make assumptions that are mainly based on market conditions existing at the end of each fiscal year. 

2.b.18) Trade receivables and other receivables 

Trade receivables are initially recognized at fair value and subsequently measured at amortized cost using the effective interest rate method. 

Under IFRS 9, a provision for bad debt is created by preparing a matrix per category and grouping the assets based on the type of customer: i) related 
parties, ii) public sector and iii) private sector. These groups were subsequently divided into sub-groups based on special characteristics indicative of the 
repayment capacity, such as i) payment arrears, ii) existence of guarantees and iii) existence of a legal proceeding already initiated or in process of 
initiation for collection purposes, among others. Once each group was defined, an expected bad-debt rate is assigned based on historical default rates 
adjusted to future economic conditions. 

The  carrying  amount  of  the  assets  is  reduced  through  the  use  of  the  provision  account,  and  the  amount  of  the  loss  is  recognized  in  the  statement  of 
comprehensive income within “Selling expenses”, as well as subsequent recoveries. 

As IFRS 9 became effective, the Group has retroactively applied the changes in the standard, without restating the comparative amounts. Therefore, the 
difference between the previous accounting amounts and the new initial amounts resulting from the initial application of the standard were recognized as 
an adjustment in the “Retained Earnings” as of January 1, 2018. The information disclosed for 2017 and 2016 reflects the requirements set forth in IAS 
39, and not those of IFRS 9 in relation to impairment of financial assets. 

In compliance with IAS 39, in fiscal years 2017 and 2016, the impairment of a financial asset was recorded only when there was an objective evidence 
of  the  impairment of  the asset,  based  on the  difference between the book value  of the  asset  and  the current value  of the  estimated  future cash flows 
(excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate. 

2.b.19) Cash and cash equivalents 

In  the  statement  of  cash  flow,  cash  and  cash  equivalents  include  cash  in  hand,  deposits  held  at  call  with  banks  and  other  short-term  highly  liquidity 
investments with original maturities of three months or less. They do not include bank overdrafts. 

2.b.20) Dividends distribution 

Dividends payable by the Group are recognized as liabilities in the period in which they are approved. 

2.b.21) Business combinations 

Business combinations are accounted for by applying the acquisition method when the Group takes effective control over the acquired company. 

The Group recognizes in its financial statements the identifiable assets acquired, the liabilities assumed, any non-controlling interest and goodwill, if 
any, in accordance with IFRS 3. 

The  acquisition  cost  is  measured  as  the  sum  of  the  consideration  transferred,  measured  at  fair  value  at  its  acquisition  date  and  the  amount  of  any 
non-controlling  interest  in  the  acquired  entity.  The  Group  will  measure  the  non-controlling  interest  in  the  acquired  entity  at  fair  value  or  at  the 
non-controlling interest’s proportionate share of the acquired entity’s identifiable net assets. 

If the business combination is achieved in stages, the Group will remeasure its previously held equity interest in the acquired entity at its acquisition date 
fair value and recognize a gain or loss in the statement of comprehensive income. 

The  goodwill  cost  is  measured  as  the  excess  of  the  consideration  transferred  over  the  identifiable  assets  acquired  and  liabilities  assumed  net  by  the 
Group. If this consideration is lower than the fair value of the assets identifiable and liabilities assumed, the difference is recognized in the statement of 
comprehensive income.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

IFRS  3  authorizes  a  term  of  12  months  from  the  acquisition  date  to  complete  the  measurement  process  of  a  business  combination.  When  this  is  not 
recorded at the closing of the fiscal year in which the business combination takes place, the Group reports provisional amounts. 

2.b.22) Total or partial disposal of foreign operation whose functional currency is other than the U.S. dollar 

On the disposal of a foreign operation (a disposal of the Group’s entire interest, or a partial disposal involving loss of control over a subsidiary), all of 
the translation differences accumulated in equity in respect of that operation attributable to the equity holders of the Company are reclassified to profit 
or loss of that fiscal year. 

In the case of a partial disposal that does not result in the Group losing control over a subsidiary that includes a foreign operation, the proportionate 
share of accumulated translation differences is reclassified to non-controlling interest and are not recognized in profit or loss. 

Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and translated 
using the closing rate. Translation differences arising are recognized in other comprehensive income. 

2.b.23) Segment Information 

Operating  segments  are  reported  in  a  manner  consistent  with  the  internal  reporting  provided  to  the  top  authority  decision-maker,  who  is  the  person 
responsible for allocating resources and assessing the performance of the operating segments. Operating segments are described in Note 5. 

2.b.24) Assets held for disposal and related liabilities 

An asset (or group of assets) is classified as held for disposal together with its related liabilities when the Group is expected to recover their value by 
means of a sale transaction (rather than through use) and where such sale is highly probable. In the event that the Group is engaged in a disposal plan, 
which  involves  the  loss  of  control  of  a  subsidiary,  it  will  classify  the assets  and  liabilities  of  such  subsidiary  as  held  for  disposal  provided  that  they 
comply with the criteria required by the IFRS 5 and its interpretations, regardless of whether the Group withholds a non-controlling interest in its former 
subsidiary after the transaction. 

In order to apply the above classification, the asset (or group of assets) must be available for its immediate disposal or dilution in its current conditions, 
exclusively subject to the usual and habitual terms for the disposal or dilution of this asset (or group of assets). 

For the transaction to be highly probable the appropriate level of Management or Board of Directors of the Company must be committed to a plan and 
an  active  program  must  have  been  actively  initiated.  In  addition,  the  disposal  of  the  asset  (or  groups  of  assets)  must  be  actively  negotiated  at  a 
reasonable price in relation to its or their current fair value. Moreover, the transaction must also be expected to meet the conditions for recognition as a 
completed disposal within one year after the classification date, with the exceptions permitted by IFRS 5, and the activities required to complete the plan 
should indicate that it is unlikely that significant changes are made to the plan or that it will be canceled. 

Assets classified as held for disposal will be measured at the lower of their carrying amount or fair value less sale-related costs. 

As of December 31, 2018, the Group classified certain areas as assets held for disposal. See Note 3. 

As of December 31, 2017, the Group classified the investment in YPF EE as an asset held for disposal. See Note 3.

2.b.25) Borrowing costs 

Borrowing costs that are directly attributable to the acquisition, construction or production of suitable assets for which a prolonged period is required to 
place them in the conditions required for their use or sale, are capitalized as part of the cost of those assets until the assets are substantially ready for use 
or  sale.  Interests  are  capitalized  according  to  the  average  debt  rate  of  the  Group.  Foreign  exchange  differences  for  loans  in  foreign  currency  are 
capitalized if they are considered an adjustment to interest costs. The rest of the borrowing costs are recognized as expenses in the period in which they 
are incurred. 

2.b.26) New standards issued 

As required by IAS 8 “Accounting policies, changes in accounting estimates and errors”, below is a brief summary of the standards or interpretations 
issued  by  the  IASB,  whose  application  is  mandatory  as  of  the  closing  date  of  these  consolidated  financial  statements,  as  well  as  of  those  whose 
application has not been mandatory as of the closing date of these consolidated financial statements and have, therefore, not been adopted by the Group.

financial statements, have been adopted by the Group, if applicable

IFRS 15 - Income from ordinary activities arising from contracts entered into with customers 

IFRS 15 is in effect for periods to be reported as from January 1, 2018, or afterwards, and may also be implemented in advance. Entities may decide 
whether to retrospectively apply the model or to use a modified transitional approach, to which the standard will be retrospectively applied only with 
regard to those contracts that are not completed by the initial date of application (e.g., January 1, 2018 for an entity with a fiscal year ended December 
31). 

It replaced the following Income Standards and Interpretations: 

•

•

•

•

•

•

IAS 18 Revenue; 

IAS 11 Construction contracts; 

IFRIC 13 Customer loyalty programs; 

IFRIC 15 Agreements for the construction of real estate; 

IFRIC 18 Transfers of assets from customers; and 

SIC 31 Revenue – Barter transactions involving advertising services. 

IFRS 15 presents a five-step approach to explain income from ordinary activities arising from contracts entered into with customers: 

1.

2.

3.

4.

5.

Identify the contract entered into with the customer. 

Identify the separable obligations of the contract. 

Determine the transaction price. 

Allocate the transaction price between the obligations of the contract. 

Recognize the income when the entity meets the obligations. 

It is mainly based on the principle that the entity has to recognize revenue to represent the transfer of goods or services promised to customers in an 
amount that reflects the consideration that the entity expects to receive in exchange for the goods or services at the time a performance obligation is 
satisfied. An asset is transferred when (or as) the customer obtains control over that asset, with control defined as the ability to direct the use of and 
obtain substantially all of the remaining benefits from the asset.

It has also introduced more prescriptive indications: 

•

•

If  the  contract  (or  a  combination  of  contracts)  contains  more  than  one  promised  good  or  service,  when  and  how  the  goods  and  services 
should be delivered. 

If the transaction price distributed to each performance obligation should be recognized as income over the course of a period of time or at a 
certain point in time. Under IFRS 15, an entity recognizes revenue when a performance obligation is satisfied, namely, when the control of 
the goods and services which has a particular obligation is transferred to the customer. The new model does not include separate guidelines 
for the “sale of goods” and the “render of services”. Instead, it requires that entities evaluate whether the revenue should be recognized over 
a period of time or at a given point in time, regardless of whether the said revenue includes “the sale of goods” or “the render of services”. 

• Where the transaction price contains an estimation of variable payments, how the amount and the time will affect the recognition of 

revenue. The concept of estimation of variable consideration is broad. A transaction price is considered variable on account of discounts, 
refunds, credits, price concessions, incentives, performance bonuses, penalties and contingency agreements. The new model introduces a 
major condition for a variable consideration to be recognized as revenue: only until it is highly improbable that a significant change in the 
accumulated revenue amount will occur, once the uncertainty associated with the variable consideration has been resolved. 

• When the incurred costs to execute a contract and the costs to perform it may be recognized as an asset. 

The accounting policies related to revenues from ordinary activities from contracts entered into with customers of the Group are described in detail in 
Note 2.b.11. 

The Group has adopted the full retrospective approach for the implementation of this standard, which has not affected the accounting policies related to 
the recognition of revenues from contracts with customers and therefore the initial retained earnings have not been affected either. 

The  Group  has  not  identified  a  significant  impact  on  its  financial  statements  with  respect  to:  (i) changes  in  transactions  within  the  scope  of  the  new 
standard;  (ii) the  identification  of  performance  obligations;  (iii) the  determination  and  distribution  of  the  price;  and  (iv) the  recognition  of  income 
accounts; with respect to the income recognition criteria previously applied. 

The Group has adopted the standard’s terminology, identifying “Contract Assets” and “Contract Liabilities”. Thus, certain reclassifications have been 
made in the comparative amounts of the statements of financial position for the fiscal year ended December 31, 2017 and 2016, as shown below:

IFRS 9 - Financial Instruments 

In  July  2014,  the  IASB  completed  the  amendment  to  the  accounting  for  financial  instruments  and  issued  IFRS  9  “Accounting  for  financial 
instruments” (in its revised version of 2014 in effect for annual periods beginning on or after January 1, 2018), which will replace IAS 39 “Financial 
Instruments: Recognition and Measurement” after the expiration of the effective date thereof. 

The following describes the key requirements of IFRS 9: 

Classification and measurement of financial assets and liabilities 

The IFRS 9 requires that all recognized financial assets that are within the scope of IAS 39 “Financial Instruments: Recognition and Measurement” be 
subsequently measured at amortized cost or at fair value. Specifically, the debt instruments that are maintained within a business model whose objective 
is  to  collect  the  contractual  cash  flows,  and  which  have  contractual  cash  flows  that  are  only  principal  and  interest  payments  on  the  amount  of 
outstanding  capital,  are  generally  measured  at  amortized  cost  at  the  end  of  subsequent  accounting  periods.  All  other  investments  in  debt  and  equity 
securities are measured at their fair values as of the closing of subsequent accounting periods. 

The most significant effect of IFRS 9 with respect to the classification and measurement of financial liabilities is related to the accounting for changes in 
the fair value of a financial liability (designated at fair value through profit or loss) attributable to the changes in the credit risk of such liability. 
Specifically, under IFRS 9, for financial liabilities that are designated at fair value through profit or loss, the amount of the change in the fair value of 
the financial liability that is attributable to changes in the credit risk of that liability is recognized in other comprehensive income, unless the recognition 
of the effects of the changes in the credit risk of the liability in other comprehensive income creates or increases a measurement inconsistency 
(accounting asymmetry) in the results. The changes in fair value attributable to the credit risk of the financial liability are not reclassified subsequently 
to the results of the fiscal year. Previously, under IAS 39, the total amount of the change in the fair value of the financial liability designated at fair value 
through profit or loss was recognized in the income statement of the fiscal year. 

The  Group  has  adopted  IFRS  9  as  of  the  transition  date  in  advance  in  accordance  with  the  regulations  in  force  in  2013,  which  deal  with  everything 
related  to  the  classification  and  measurement  of  financial  assets  and  liabilities,  so  it  is  not  expected  that  there  will  be  an  impact  on  the  described 
treatments. 

Hedge accounting 

The  general  hedge  accounting  requirements  of  IFRS  9  maintain  the  three  types  of  hedge  accounting  mechanisms  included  in  IAS  39.  However,  the 
eligible  types  of  hedge  accounting  transactions  are  now  much  more  flexible,  especially  by  expanding  the  types  of  instruments  that  are  classified  as 
hedging instruments and the types of risk components of non-financial elements ideal for hedge accounting. 

In addition, the effectiveness test has been reviewed and replaced by the principle of “economic relationship”. A retrospective evaluation is no longer 
required  to  measure  the  effectiveness  of  the  coverage.  Many  more  disclosure  requirements  have  been  added  regarding  the  entity’s  risk  management 
activities. 

The  initial  application  of  this  standard  related  to  hedge  accounting,  has  not  had  any  impact  because  the  Group  has  not  carried  out  these  types  of 
transactions in the fiscal years ended December 31, 2018, 2017 and 2016. 

Impairment Methodology 

The impairment model in accordance with IFRS 9 reflects expected credit losses, as opposed to credit losses incurred under IAS 39. In regard to the 
impairment  in  IFRS  9,  it  is  no  longer  necessary  for  a  credit  event  to  occur  before  it  is  incurred.  In  contrast,  an  entity  always  accounts  for  both  the 
expected credit losses and their changes. The amount of expected credit losses must be updated on each reporting date to reflect changes in credit risk 
from initial recognition. 

The Group estimated the impairment of its financial assets and contract assets in compliance with the accounting policy outlined in Note 2.b.18 to these 
consolidated financial statements.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

Thereby, it is replaced the previous accounting policy under which the impairment of a financial asset was recorded only when there was an objective 
evidence of the impairment of the asset, based on the difference between the book value of the asset and the current value of the estimated future cash 
flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate. 

In  compliance  with  the  exception  provided  under  IFRS  9,  the  Group  has  retroactively  applied  the  changes  in  the  standard,  without  restating  the 
comparative  amounts.  Therefore,  the  difference  between  the  previous  accounting  amounts  and  the  new  initial  amounts  resulting  from  the  initial 
application  of  the  standard  were  recognized  as  an  adjustment  in  the  “Retained  Earnings”  as  of  January 1,  2018.  The  information  disclosed  for  2017 
reflects  the  requirements  set  forth  in  IAS  39,  and  not  those  of  IFRS  9  in  relation  to  impairment  of  financial  assets.  The  implementation  of  the 
impairment method introduced by the standard generated a loss of 425 with the consequent effect on the deferred tax of 127. The net effect shown in the 
statement of changes in shareholders’ equity was 298, not being significant for the financial position and/or performance of the Group.

Amendments to IAS 40 – Investment Properties 

In December 2016, the IASB made amendments to IAS 40 applicable to fiscal years beginning on or after January 1, 2018. 

IAS 40 has been modified to reflect that in relation to transfers, an entity will transfer an investment property to, or from investment properties when, 
and only when, there is a change in use. This change in use occurs when a property meets or fails to meet the definition of investment property and there 
is evidence of a change in use. It also clarifies that the change in the management’s intentions regarding the use of a property does not provide evidence 
of a change of use. 

The adoption of the foregoing modifications did not have any effects on the consolidated financial statements of the Group. 

•

Amendments to IFRS 4 – Application of IFRS 9 “Financial Instruments” with IFRS 4 “Insurance Contracts” 

In September 2016, the IASB issued amendments to IFRS 4 that are applicable to those fiscal years beginning on or after January 1, 2018. 

The adoption of the foregoing modifications did not have any effects on the consolidated financial statements of the Group. 

•

Amendments to IFRS 2 – Classification and Measurement of Share-based Payment Transactions 

In June 2016, the IASB amended IFRS 2, and such amendments are to be applied for fiscal years beginning on or after January 1, 2018, though they 
may be implemented in advance. 

IFRS 2 has been amended to reflect the following: 

•

•

For share-based payment transactions that are settled in cash, the goods or services purchased and the liability, which they incur, will be measured 
at the fair value of the liability, subject to the requirements of this standard. Until the liability is settled, the fair value of the liability is remeasured 
at the end of each reporting period, as well as on the settlement date, recognizing any change in fair value in the results for the period. 

The conditions for the irrevocability of concession and conditions other than the irrevocability of the concession, other than market conditions, 
will  not  be  taken  into  account  when  estimating  the  fair  value  of  the  share-based  payment  that  is  settled  in  cash  on  the  date  of  measurement. 
Instead,  they  will  be  taken  into  account  by  adjusting  the  number  of  incentives  included  in  the  measurement  of  liabilities  arising  from  the 
transaction.  Accordingly,  an  amount  will  be  recognized  for  the  goods  or  services  received  during  the  period  up  to  the  irrevocability  of  the 
concession. This amount will be based on the best available estimate of the number of incentives that are expected to be irrevocable.

•

If the terms and conditions of a share-based payment transaction to be settled in cash are modified to become a share-based payment transaction 
that is settled by equity securities, such transaction will be accounted for as of the date of the modification. Specifically: (a) a share-based payment 
transaction  that  is  settled  by  equity  securities  is  measured  by  reference  to  the  fair  value  of  the  equity  securities  granted  on  the  date  of  the 
modification. The share-based payment transaction settled by equity securities is recognized in equity on the date of the change, in proportion to 
the  goods  or  services  that  have  been  received;  (b) the  liability  for  the  share-based  payment  transaction  settled  in  cash  on  the  date  of  the 
amendment will be written off in the accounts on the same date; and (c) any difference between the carrying amount of the written off liability and 
the amount of equity recognized on the date of the change will be recognized immediately in the income statement for such period. 

The adoption of the foregoing modifications did not have any effects on the consolidated financial statements of the Group.

IFRIC 22 – Transactions in Foreign Currency and Advance Payments 

In December 2016, the IASB approved the interpretation of IFRIC 22 “Transactions in foreign currency and advance payments”, which is applicable for 
the fiscal years beginning on or after January 1, 2018, though they may be implemented in advance. The scope of this interpretation applies to a foreign 
currency  transaction  (or  any  part  thereof)  where  an  entity  recognizes  a  non-financial  asset  or  non-financial  liability  arising  from  the  payment  or 
collection of an early consideration before the entity recognizes the asset, expense or related income (or any part thereof that may be appropriate). This 
interpretation  does  not  apply  when  an  entity  measures  the  related  asset,  expense  or  income  at  the  time  of  the  initial  recognition:  (a) at  fair  value;  or 
(b) the fair value of the consideration paid or received as of a date other than that of the initial recognition of the non-monetary asset, or non-monetary 
liability, arising from the anticipated consideration (e.g., measurement of the goodwill by applying the IFRS 3 “Business Combinations”). 

The adoption of the foregoing modifications did not have any effects on the consolidated financial statements of the Group.

IFRS 16 – Leases

Type of modification 

IFRS  16  was  issued  in  January  2016.  Under  this  standard  all  leases  will  be  recognized  in  the  statement  of  financial  position  by  lessees,  since  the 
distinction between finance and operating leases is eliminated. The new standard recognizes a financial asset (the right to use the leased item) and a 
financial liability to pay the lease. The only exceptions are short-term and low value leases. 

Description of IFRS 16 requirements 

IFRS 16 is in effect for reporting periods beginning on January 1, 2019 and its implementation in advance is permitted for entities that have applied 
IFRS 15 “Revenue from ordinary activities from contracts entered into with customers” prior to the date of initial application of IFRS 16. 

It will replace IAS 17 “Leases” and its interpretations after the effective date thereof. 

IFRS 16 sets out the principles required for the recognition, measurement, presentation and disclosure of leases. The purpose thereof is to ensure that 
lessees and lessors provide relevant information in a way that faithfully represents those transactions. The changes incorporated by such standard mainly 
impact the lessees accounting. 

This standard applies to all leases, including leases of rights-of-use assets in a sublease, with the exception of specific leases covered by other standards: 

•

•

•

•

•

Leases to explore or use minerals, oil, natural gas and similar non-renewable resources; 

Leases of biological assets within the scope of IAS 41 “Agriculture” kept by a lessee; 

Contracts included in the scope of application of IFRIC 12 “Service Concession Agreements”; 

Intellectual property licenses granted by a lessor within the scope of IFRS 15 “Revenue from contracts with customers”; and 

Rights kept on by a lessee under license agreements that are within the scope of IAS 38 “Intangible assets” for items such as movies, videos, 
games, manuscripts, patents and copyrights. 

The model introduced by this standard is based on the definition of the term “lease”, which is mainly related to the concept of control. IFRS 16 makes a 
difference between lease contracts and service contracts on the basis of whether an identified asset is under the customer’s control, which is deemed to 
exist if the customer has the right to: i) substantially obtain all the economic benefits from the use of the asset; and ii) control the use of the asset. 

Lessor’s accounting: 

IFRS 16 requires the lessor to classify the lease as operating or finance. A finance lease is a lease in which substantially all the risks and benefits derived 
from ownership of the asset are transferred. A lease will be classified as operating if it does not transfer substantially all the risks and benefits derived 
from the ownership of an underlying asset.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

The classification of the lease is made on the effective date of the agreement and is evaluated again only if there is an amendment to the lease. Changes 
in estimates (e.g., changes in the economic life or in the residual value of the underlying asset) or changes in circumstances (e.g., non-compliance by the 
lessee) will not result in a new classification of the lease for accounting purposes. 

Lessee’s accounting: 

The standard establishes that once the lease is identified, an entity should recognize the following items: 

•

Right-of-use asset, whose cost includes: 

(a)

(b)

(c)

(d)

the amount of the initial measurement of the lease liability (as described below); 

any rent paid to the lessor prior to the commencement date or on the same date, after discounting any incentive received for the lease; 

the initial direct costs incurred by the lessee; and 

an estimate of the costs to be incurred by the lessee in dismantling and eliminating the underlying asset, restoring the place where the 
underlying asset is located or restoring the underlying asset to the condition required by the terms and conditions of the lease, unless such 
costs are incurred at the time of making of the inventories. The lessee could incur in certain obligations because of such costs either on the 
date of commencement of the term of the lease, or because of having used the underlying asset during a specified period. 

Subsequently, the valuation of the right of use of assets will be based on the cost model or the revaluation model under IAS 16 “Property, Plant 
and Equipment” (recognizing therefore the amortization and impairment in the profit and loss account and, if applicable the revaluation model, 
revaluations  in  equity).  However,  the  IFRS  16  requires  that  the  right  to  use  a  leased  property  investment  be  valued  at  its  fair  value  under  the 
provisions set forth in IAS 40 “Investment properties” for the investment property it holds. 

•

Lease liability, measured at the present value of the lease payments that have not been paid on that date. Lease payments will be discounted using 
the interest rate implied in the lease, if that rate could be easily determined. If that rate cannot be easily determined, the lessee will use the lessee’s 
incremental borrowing rate. 

Lease liabilities must include the following items: 

(a)

(b)

(c)

(d)

(e)

fixed payments (including in substance fixed payments), less any lease incentive receivable; 

variable payments, which depend on an index or a rate, initially measured by using the index or rate (e.g., payments related to the consumer 
price index, prices related to a benchmark interest rate such as LIBOR, or payments that vary to reflect changes in market rental prices) on 
the effective date of the contract; 

amounts that the lessee expects to pay as residual value guarantees; 

the price of the purchase option if the lessee is reasonably certain to exercise that option; and 

payment of penalties for terminating the lease, if the lease period reflects that the lessee will exercise an option to terminate it (i.e., because 
there is a reasonable certainty thereon). 

Subsequently, the lessee will increase the liability for the lease to reflect the accrued interest (and recognized in the income statement), deduct the 
installments that are being paid from such liability and recalculate the book value to reflect any review, amendment to the lease or review of the 
so-called “in-substance” fix payments.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

The lessee must review the lease liability in the following cases: 

(a) when there is a change in the amount expected to be paid under a residual value guarantee; 

(b) when there is a change in future rental payments to reflect the variation of an index or an interest rate used to determine such rental 

payments (including, for example, a market rent review); 

(c) when there is a change in the term of duration of the lease as a result of a change in the non-cancellable period of the lease (for example, if 

the lessee does not exercise an option previously included in the determination of the lease period); or 

(d) when there is a change in the evaluation of the purchase option of the underlying asset. 

Preliminary assessment 

During fiscal year 2018, the Group has developed the IFRS 16 implementation project to evaluate the application effects of this standard, including the 
impacts on the consolidated financial statements, key performance indicators and financial metrics, as well as the development of accounting policies. 
Additionally, an evaluation of the necessary changes in the  systems  and processes has  been carried out. For these purposes, the Group has reviewed 
substantially all of the Group’s leasing arrangements in light of the new lease accounting rules in IFRS 16. 

Based on such analysis, it was preliminary concluded that the new definition of lease does not significantly change the scope of the contracts deemed as 
leases. 

The Group expects to recognize right-of-use assets and lease liabilities of about 23,059, as of January 1, 2019, in the consolidated statement of financial 
position measured at the present value of future lease payments. 

Regarding the comprehensive statement of income, the Group expects that the net fiscal year result will decrease by about 541 for fiscal year 2019, as a 
result of recognizing depreciations of right-of-use assets and the accrual of interest of lease liabilities. 

On the other hand, as the payment of the principal portion of lease liabilities will be classified as cash flows from financing activities, the Group expects 
a decrease thereof and that cash flows from operating activities will increase in about 9,224 for 2019. 

The application of this standard will have no effect on the retained earnings since the Group intends to apply the simplified model without restating any 
comparative  figures,  recognizing  a  right-of-use  asset  equivalent  to  the  lease  liability  on  the  initial  date  of  transition  (January  1,  2019).  There  are  no 
adjustments to be made due to impairment arising from the provision for onerous contracts related to these right-of-use assets. 

With  regard  to  short-term  leases,  and  leases  of  low-value  assets,  the  Group  intends  to  continue  recognizing  them  as  straight-line  expense  over  the 
effective term of the lease, unless another systematic basis is more representative, in accordance with the option indicated by the standard. 

Moreover, the Group intends to apply the practical solution of the standard whereby leases expiring within the term of 12 months from the date of the 
initial  application,  regardless  of  the  original  date,  and  which  comply  with  the  conditions  to  be  classified  as  short  term  leases,  follow  the  treatment 
described in the previous paragraph. 

The group’s activities as a lessor are not material and hence the Group does not expect any significant impact on the financial statements.

IFRS 9 – Prepayment with negative compensation

In October 2017, an amendment was introduced in connection with the feature of prepayment with negative compensation, whereby the lender (i.e., the 
holder) might be forced to accept in payment a prepayment amount that is substantially lower than the unpaid amounts of principal and interest. In these 
cases,  the  amendment  proposes  that  financial  assets  with  this  feature  should  be  measured  at  amortized  cost  or  fair  value  with  changes  in  other 
comprehensive income. 

The Group estimates that the implementation of this last amendment, effective as from January 1, 2019, which may be applied in advance, will not have 
a significant impact on its financial statements as the Group does not perform this type of transactions.

IFRIC 23 – Uncertainty about income tax treatment

The  Interpretation  issued  in  June  2017  clarifies  how  to  apply  the  recognition  and  measurement  requirements  of  IAS  12  when  there  is  uncertainty 
regarding income tax treatment. 

For such purpose, the entity must evaluate whether the tax authority will accept an uncertain tax treatment used, or proposed to be used, or which is 
intended to be used in its income tax filing. 

If an entity concludes that the tax authority is likely to accept an uncertain tax treatment, the entity will determine the tax position consistent with the tax 
treatment used or intended to be used on its income tax filing. If an entity concludes that such acceptance is improbable, the entity will reflect the effect 
of the uncertainty in determining the fiscal result, the tax bases, unused tax losses, unused tax credits and tax rates. An entity will reflect the effect of the 
uncertainty for each uncertain tax treatment by using one of the following methods, depending on which method the entity expects to better predict the 
resolution of the uncertainty: 

•

•

The most probable amount—the only most probable amount in a range of possible outcomes. The most probable amount may better predict the 
resolution of the uncertainty if the possible outcomes are dual or are concentrated in a value. 

The expected value—the addition of the amounts weighted by their probability in a range of possible outcomes. The expected value may better 
predict the resolution of the uncertainty if there is a range of possible outcomes that are not dual or are concentrated in a value. 

This amendment will be effective for the fiscal years beginning on or after January 1, 2019 and may be early applied. 

The Group estimates that the application of the aforementioned interpretation will not have a significant effect on its financial statements. Additionally, 
see Note 28.b.4. 

•

Amendments to IAS 28 – Long-term Investments in associates and joint ventures

In October 2017, the IASB issued amendments to IAS 28, which are applicable to the fiscal years beginning on or after January 1, 2019, allowing early 
application. 

The amendment defines that the long-term investments in associates and joint ventures, which are not accounted for using the equity method, will be 
accounted for in accordance with IFRS 9. 

The Group estimates that the application of the aforementioned interpretation will not have a significant effect on its financial statements.

IFRS 17 – Insurance contracts

The IFRS 17 issued in May 2017 is applicable to those fiscal years beginning on or after January 1, 2021, allowing its early application and replacing 
IFRS 4. 

The Group does not anticipate that this standard will have effects on its financial statements because it does not provide this type of services. 

•

Amendments to IFRS 10 and IAS 28 – Sale or contribution of assets between an investor and its associate or joint venture 

In September 2014, the IASB amended IFRS 10 and IAS 28 to clarify that in transactions involving a controlled company, the extent of the gain or loss 
to be recognized in the financial statements depends on whether the sold or contributed controlled company is considered a business in accordance with 
IFRS 3. 

On August 10, 2015, the IASB issued a proposal to postpone the effective date of these changes indefinitely depending on the outcome of its research 
project on accounting by the equity method, which was approved on December 17, 2015.

Annual improvements to IFRS – 2015-2017 Cycle

In December 2017, the IASB issued the 2015-2017 cycle of annual improvements that are applicable for the years beginning on or after January 1, 2019, 
allowing early application. 

A summary of the main modified standards and their purpose follows: 

Standard

“Joint

Detail
The amendment to IFRS 3 establishes that when obtaining control of a business that 
was  a  joint  operation,  the  acquirer  will  apply  the  requirements  for  a  business 
combination  carried  out  in  stages,  including  the  re-measurement  of  its  previously 
held share in the joint operation at the fair value on the acquisition date. On the other 
hand,  the  amendment  to  IFRS  11  establishes  that  when  obtaining joint  control  of  a 
business  that  was  a  joint  operation,  it  does  not  measure  again  its  previously  held 
shares.

IAS 12 “Income Tax”

Exposure  of 
dividends on Income Tax

The  amendment  clarifies  that  the  entity  will  recognize  the  consequences  of  the 
dividends on the income tax where it has recognized the transactions or events that 
gave rise to those distributable profits.

IAS 23 “Borrowing Costs”

Capitalization 
loans

of 

generic 

The  amendment  to  this  standard  clarifies  that,  for  the  capitalization  of  costs  from 
generic  loans,  it  must  necessarily  consider  all  outstanding  loans  when  determining 
the capitalization rate, except those taken specifically to finance an eligible asset that 
is not yet ready for its intended use or sale; i.e., if any specific loan remains unpaid 
after  the  related  eligible  asset  is  ready  for  its  intended  use  or  for  sale,  that  loan 
becomes part of the funds that the entity took as generic loans.

The Group estimates that the application of the amendments to the mentioned standards will not have a significant effect on its financial statements.

Amendments to IAS 19 – Employee benefits

In  February  2018,  the  IASB  issued  amendments  to  this  standards’  guidance,  in  relation  to  the  accounting  for  Plans  amendments,  curtailments  and 
settlements. 

An  entity  shall  determine  the  cost  of  services  for  the  current  period  and  the  net  interest  for  the  remainder  of  the  annual  period,  using  actuarial 
assumptions determined at the beginning of the annual reporting period. However, if an entity remeasures the liability (asset) for net defined benefits, it 
will determine the current cost of the service and the net interest for the remainder of the annual period, using actuarial assumptions updated after the 
plan change. 

Another modification consists in recognizing in results any reduction in the surplus, even if that surplus was not previously recognized due to the impact 
of the asset ceiling. 

The Group estimates that the application of this amendment, effective as of January 1, 2019, allowing early application, will not have any significant 
effects on its financial statements. 

•

Amendments to IFRS 3 – Business combinations

In October 2018, the IASB has issued Definition of a Business (Amendments to IFRS 3), aimed at resolving the difficulties that arise when an entity 
determines whether it has acquired a business or a group of assets. The amendments are effective for business combinations for which the acquisition 
date is on or after the beginning of the first annual reporting period beginning on or after 1 January 2020. Early application is allowed. 

•

The amendments:

•

•

•

•

•

clarify that to be considered a business, an acquired set of activities and assets must include, at least, an input and a substantive process that 
together significantly contribute to the ability to create outputs; 

remove the assessment of whether market participants are capable of replacing any missing inputs or processes and continuing to produce 
outputs; 

add guidance and illustrative examples to help entities assess whether a substantive process has been acquired; 

narrow the definitions of a business and of outputs by focusing on goods and services provided to customers and by removing the reference 
to an ability to reduce costs; and 

add an optional concentration test that permits a simplified assessment of whether an acquired set of activities and assets is not a business. 

The Group estimates that the application of these amendments will not have significant effects on its financial statements. 

•

Amendments  to  IAS  1  “Presentation  of  financial  statements”  and  IAS  8  “Accounting  policies,  changes  in  accounting  estimates  and 
errors” – Definition of material

In  October  2018,  the  IASB  issued  amendments  that  are  applicable  to  fiscal  years  beginning  on  or  from  January 1,  2020,  allowing  for  its  anticipated 
application. 

The  amendments  to  the  definitions  of  “material”  or  “with  relative  importance”  seek  to  unify  the  definition  of  such  concepts  to  the  definitions  of 
Conceptual Framework, also amended in 2018. 

The Group estimates that the implementation of these amendments will not affect its financial statements. 

•

Amendments to References to the Conceptual Framework for Financial Reporting

In March 2018, the IASB issued the revised Conceptual Framework applicable to annual periods beginning on or after January 1, 2020. This revision 
process did not imply a substantial change in the set of definitions, concepts and guidelines used as a basis for preparing financial information.

2.c) Accounting Estimates and Judgments 

The  items  in  the  financial  statements  and  areas  which  require  the  highest  degree  of  judgment  and  estimates  in  the  preparation  of  these  financial 
statements are: 

Crude oil and natural gas reserves 

Estimating crude oil and gas reserves is an integral part of the Group’s decision-making process. The volume of crude oil and gas reserves is used to 
calculate depreciation using the unit of production ratio and to assess the impairment of the capitalized costs related to the Upstream assets (see Notes 
2.b.8, 2.b.9 and the last paragraph of this Note). 

The Group prepares its estimates of crude oil and gas reserves in accordance with the rules and regulations established for the crude oil and natural gas 
industry by Rule 4-10 (a) of Regulation S-X of the SEC. 

Provision for litigation and other contingencies 

The final costs arising from litigation and other contingencies, and the perspective given to each issue by the Management of the Company may vary 
from their estimates due to different interpretations of laws, contracts, opinions and final assessments of the amount of the claims. Changes in the facts 
or circumstances related to these types of contingencies and the strategy defined in each case can have, consequently, a significant effect on the amount 
of the provisions for litigation and other contingencies recorded or the perspective given by the Management of the Company. 

Provision for environmental costs and obligations for the abandonment of hydrocarbon wells 

Given the nature of its operations, the Group is subject to various laws and regulations relating to the protection of the environment. These laws and 
regulations  may,  among  other  things,  impose  liability  on  companies  for  the  cost  of  pollution  cleanup  and  environmental  damages  resulting  from 
operations.  YPF  management  believes  that  the  Group’s  operations  are  in  substantial  compliance  with  laws  and  regulations  of  Argentina  and  the 
countries where the Group operates, relating to the protection of the environment as such laws have historically been interpreted and enforced. 

The Group periodically conducts new studies to increase its knowledge of the environmental situation in certain geographic areas where it operates in 
order to establish the status, cause and remedy action of a given environmental issue and, depending on its years of existence, analyze the Argentine 
Government’s possible responsibility for any environmental liabilities existing prior to December 31, 1990. The Group cannot estimate what additional 
costs, if any, will be required until such studies are completed and evaluated; however, provisional remedial actions or other measures may be required. 

In  addition  to  the  hydrocarbon  wells  abandonment  legal  obligation,  the  Group  has  accrued  environmental  remediation  which  evaluations  and/or 
remediation  works  are  probable  and  can  be  reasonably  estimated,  based  on  the  Group’s  existing  remediation  program.  Legislative  changes,  on 
individual costs and/or technologies may cause a re-evaluation of the estimates. The Group cannot predict what environmental legislation or regulation 
will be enacted in the future or how future laws or regulations will be administered. In the long-term, these potential changes and ongoing studies could 
materially affect the Group’s future results of operations. 

The main guidelines on the provision for the obligations for the abandonment of hydrocarbon wells are set forth in detail in Note 2.b.6. 

Income tax and deferred income tax 

The  proper  assessment  of  income  tax  expenses  depends  on  several  factors,  including  interpretations  related  to  tax  treatment  for  transactions  and/or 
events that are not expressly provided for by current tax law, options established by the law or its regulations, as well as estimates of the timing and 
realization of deferred income taxes. The actual collection and payment of income tax expenses may differ from these estimates due to, among others, 
changes in applicable tax regulations and/or their interpretations, as well as unanticipated future transactions affecting the Group’s tax balances.

Provision for impairment of property, plant and equipment and intangible assets 

The methodology used in estimating the recoverable amount of property, plant and equipment and intangible assets is detailed in Note 2.b.8 and 2.b.9. 

The determination of whether an asset is impaired, and by how much, involves management’s estimates of highly uncertain matters such as the effects 
of inflation and deflation on operating expenses, discount rates, production profiles, reserves and future prices of the products, including the prospects of 
supply and demand conditions of the world or regional market for crude oil, natural gas and refined products, all of which affects the prices taken into 
account in the projection. Consequently, for oil and natural gas assets, the expected future cash flows are determined using management’s best estimate 
of future oil and natural gas prices and production volumes and reserves. The foregoing implies the use of assumptions about future commodity prices, 
production and development costs, field decline rates, current tax regimes and other factors. These assumptions and the management decisions on which 
the estimates of expected cash flows are based are subject to changes as new information becomes available. Changes in economic conditions may also 
affect the rate used to discount future cash flow estimates. 

In  general,  the  Group  does  not  consider  temporarily  low  (or  high)  prices  or  margins  as  an  indication  of  impairment  (or  reversal  of  an  impairment 
charge).  The  impairment  assessment  mainly  reflects  long-term  oil  and  natural  gas  prices  that  are  consistent  with  intermediate  points  between  the 
maximum and minimum ranges observed in the market and that are in the range of price forecasts published by third-party experts of the industry and 
government agencies, within which are the long and short term projections of the “US Energy Information Administration” and the Brent crude forward 
curve. The assumptions of future prices used by the Management of the Company tend to be stable because it does not consider short-term increases or 
decreases  in  prices  to  be  indicative  of  long-term  levels,  but  they  are  subject  to  change.  Besides,  oil  prices  do  no  rise  above  the  historical  oil  prices 
observed  in  the  past,  applied  to  projected  future  production  volumes.  Gas  prices  correspond  to  the  average  weighted  price  per  basin  and  channel, 
determined according to the market’s supply and demand. 

With regard to the oil market of prior periods, the applicable domestic prices of petroleum products were established for the short term mainly based on 
negotiations between Producers and Refiners of the country, without keeping a direct or specific reference with respect to the international quotations of 
such products. In 2016, due to the continued fall in international average prices for Brent crude oil, it was agreed to reduce in about 10% the domestic 
crude oil price per barrel with respect to effective price as of December 31, 2015. Additionally, in August 2016, a new agreement between producers, 
refiners and  the  MINEM  allowed  for  a  new  gradual reduction  in  the  domestic crude oil  price  per barrel  in  a  monthly  2% in  August,  September  and 
October, reaching an accumulated 6% drop by November 2016. 

As detailed on Note 30.e., in January 2017, Producers and Refiners reached a new agreement in which a path of prices was established for the sale of oil 
in the domestic market for the purpose of achieving parity with the international markets during 2017, which took place during the last quarter of 2017. 

In relation with the gas market, incentive schemes were established in recent years in order to increase the total injection of natural gas (see Note 30.g). 
In particular, in 2018 an excess in the supply with respect to the domestic demand took place at specific times of the year, an unusual situation in the 
past, which affected natural gas production due to the temporary shutdown of wells, as well as to the reinjection of the hydrocarbon. In this new scenario 
and under the new regulations (see Note 30) and agreements, domestic gas prices declined, and therefore it is expected a future reduction in natural gas 
sales prices compared to those contemplated in the 2017 projections.

BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

Based on the aforementioned methodology, the expected decrease in the crude oil price as of December 31, 2016 together with the evolution of the cost 
behavior in terms of macroeconomic variables and the operational behavior of the Group’s assets, caused CGU Oil to record an impairment charge for 
property, plant and equipment in the Upstream segment of 34,943 as of December 31, 2016. 

The discount rate after taxes used as of December 31, 2016 was 8.67%, the recoverable value, after taxes, as of such date of the CGU Oil was 71,495. 

As of December 31, 2017, the Group recognized a reversal in the charge for impairment of the value of its assets for the CGU Oil of 5,032, which arises 
from  the  combination  of  multiple  factors,  such  as  the  variation  in  production  and  associated  investments  considered  in  the  cash  flows,  the  effect  of 
variations in operating and abandonment costs, the variation in the discount rate and, to a lesser extent, the variation in oil prices, taking into account 
also the book value of the assets as of December 31, 2017 affected by depreciation charges for the year and investments made, among others. 

The discount rate after taxes used as of December 31, 2017 was 8.28% for 2018 and 2019 and 8.42% for 2020 and thereafter, the recoverable value after 
taxes as of such date of the CGU Oil was 82,802. 

As of December 31, 2018, the Group recognized a reversal in the charge for impairment of the value of its assets for the CGU Oil of 39,837 and an 
impairment charge of property, plant and equipment, mainly for the CGU Gas – Neuquina Basin of 28,326 and CGU Gas – Austral Basin of 8,246. 

The reversal of impairment charge of the CGU Oil assets is mainly due to the increase in oil reserves coupled with estimated cost improvements, all of 
which is mainly set off by: (i) the rise in the discount rate as a result of the higher country risk and cost of debt and (ii) larger investments associated to 
higher reserves contemplated in cash flows. All the foregoing taking into account the book value of assets as of December 31, 2018, affected by the 
deprecation charges for the fiscal year and the investments made, among others. 

The impairment of the CGU Gas – Neuquina Basin and CGU Gas – Austral Basin assets arises from a combination of multiple factors, mainly from the 
anticipated reduction in gas market prices due to the lower sales price to distributors and power plants (see Note 30 in sections “Terms and Conditions 
for the Distribution of Natural Gas through Networks” and “Natural Gas Sales for Electricity Generation”) and the higher discount rate due to higher 
country risk and cost of debt, all of which is partially set off by a reduction in costs. 

The discount rate after taxes used as of December 31, 2018 was 10.94% for 2019 and 11.19% for 2020 and thereafter, the recoverable value after taxes 
as of such date of the CGU OIL, CGU Gas – Neuquina Basin and CGU Gas – Austral Basin are 254,549, 108,509 and 8,606, respectively. 

As mentioned above, as of the fiscal year end 2018, the Company’s Management does not anticipate any relevant changes in long-term price curves, as 
it  does  not  consider  the  recent  (positive)  changes  in  commodity  prices,  all  the  foregoing  taking  into  account  the  high  volatility  observed,  until  the 
variables affecting them shall evidence certain stability in the course of time. 

2.d) Comparative Information 

Balance items as of December 31, 2017 and 2016 presented in these financial statements for comparison purposes arise from the consolidated financial

Agreement for YPF EE’s capitalization

On  December 14,  2017,  the  Board  of  Directors  of  the  Company  approved  the  terms  of  a  memorandum  of  understanding  signed  with  GE  Energy 
Financial Services, Inc. (“GE EFS”) which established the framework conditions under which the parties would agree to the capitalization of YPF EE. 
This Agreement, the framework conditions of which were approved by the Board of Directors of the Company, established that GE EFS intended to 
contribute capital through a vehicle company and subscribe for shares of YPF EE in order to have a shareholding of 25% of its capital stock. 

As of December 31, 2017, the Group had classified its investment in YPF EE as assets and liabilities held for disposal in separate lines from the rest of 
the assets and liabilities, given that as of that date they had met all the requirements for this classification (see Note 2.b.24). Given that, at the time of 
classification,  the  fair  value  less  costs  of  the  transaction  was  higher,  the  investment  in  YPF  EE  has  been  valued  at  its  book  value,  therefore,  no 
impairment has been recorded at the time of reclassification. Although YPF EE represented a component within YPF because it was an individual CGU 
within  the  Gas  and  Energy  segment,  it  did  not  qualify  as  a  discontinued  operation  since  it  did  not  represent  a  significant  line  of  business  nor  a 
geographical area. 

On  February 6,  2018,  YPF  entered  into  a  definitive  and  binding  agreement  with  EFS  Global  Energy  B.V.  (“GE”)  and  GE  Capital  Global  Energy 
Investments  B.V.,  companies  indirectly  controlled  by  GE  EFS,  which  establishes  the  conditions  for  the  capitalization  of  YPF  EE  (the  “Share 
Subscription  Agreement”).  The  Share  Subscription  Agreement  establishes  that,  subject  to  compliance  with  certain  conditions  precedent,  GE  will 
subscribe for shares of YPF EE in order to achieve a participation equal to 24.99% of its capital stock and jointly control this company with YPF. 

On March 20, 2018, GE EFS Power Investments B.V., a subsidiary of EFS Global Energy B.V  (both companies indirectly controlled by GE Energy 
Financial Services, Inc.; jointly “GE”), subscribed YPF EE shares representing 24.99% of its capital stock. Since then, GE EFS Power Investments and 
YPF jointly control YPF EE, undertaking to contribute as follows: 

•

Subscription price of US$ 275 million: 

•

•

US$ 135 million on the closing date of the transaction; and 

US$ 140 million 12 months after the closing date of the transaction. 

•

Contingent price of up to the maximum sum of US$ 35 million subject to the evolution of the electric market prices (33.33% as of 24 months from 
the closing date of the transaction and 16.67% each subsequent year).

As a result of the implementation of IFRS 10 and the aforementioned capitalization process of YPF EE, the Group recorded a gain of 11,980 (11,879 
through YPF and 101 through OPESSA) included in the item “Other net operating results”, which includes a gain of 13,552 (13,451 through YPF and 
101 through OPESSA) due to the dilution of its interest in YPF EE with the consequent loss of control over it and the subsequent revaluation of its 
residual interest (3,438 y 10,114, respectively) and a loss of 1,572 (fully corresponding to YPF) for the reversal to net profit for the period of the accrued 
translation corresponding to the investment in this Company. 

In order to determine the fair value of the investment in YPF EE, the Group has considered all the elements available as of the date of these financial 
statements, including the best estimation of the occurrence of the contingent payments provided in the operation. However, for the measurement of this 
fair  value  the  Group  has  a  term  of  one  year  to  evaluate  all  the  facts  and  circumstances  existing  as  of  the  transaction  date  that  might  modify  such 
measurement. 

Regarding  the  participation  held  after  the  aforementioned  transaction,  the  Group  has  followed  the  guidelines  of  IFRS  10  “Consolidated  financial 
statements” and has concluded that from the entry of GE in YPF EE, GE and YPF jointly control YPF EE. Consequently, the Group applied IFRS 11 
“Joint  Arrangements”  defining  such  company  as  a  joint  venture,  and  measured  it  according  to  the  equity  method  under  the  IAS  28  “Investments  in 
associates and joint ventures”. 

Some of the main evaluated assumptions are described below: 

(i)

Any decisions about the relevant activities of YPF EE thereof are to be taken jointly, there being no power of one shareholder over the other in 
relation to such activities, regardless of the different percentages of equity interests held in YPF EE by each of them. Although the Group owns a 
75.00001% stake in YPF EE, according to the shareholders’ agreement, the following is required for decision-making purposes regarding the 
relevant activities: the approval of at least one Director appointed by each class of shares at the meeting of the Board of Directors and the approval 
of each class of shares for the adoption of such decisions at the Shareholders’ meeting; 

(ii) No shareholder has any power, as defined in IFRS 10, to the detriment of any other, independently of the number of Directors or personnel (key or 
not) appointed by each class of shares, in the management of the Company for its own benefit or to unilaterally modify the variable investment 
returns or ultimately, to unilaterally direct any of the decisions associated with the relevant activities.

Acquisition of strategic assets of Oil Combustibles S.A. (“Oil”)

On May 11, 2018, Oil’s bankruptcy was determined and, by means of a resolution dated June 1, 2018, the intervening judge decided to grant YPF and 
Destilería  Argentina  de  Petróleo  S.A.  (“DAPSA”)  the  management  of  Oil  in  accordance  with  the  terms  of  the  offer  presented  by  both  companies, 
pursuant to which YPF and DAPSA were entitled for a two-month period to use the logistic assets (docks and fuel storage tanks located in the Oil River 
Terminal  on  the  Paraná  River),  to  exclusively  and  directly  supply  fuel  to  the  entire  network  of  Oil  gas  stations  by  DAPSA,  and  to  match  the  best 
purchase offer made by any third party, whether for the whole or a part of Oil’s facilities, and for the exclusive supply of Oil’s commercial network as 
part of the liquidation process of Oil’s assets. 

On  July 27,  2018,  YPF  and  DAPSA  filed  a  brief  stating  that  they  were  able  to  continue  the  management  for  two  additional  months  under  certain 
conditions, which was accepted by the bankruptcy trustee and the judge. 

The hearing for the opening of bids for the parties interested in acquiring Oil’s industrial assets, originally scheduled for September 14, 2018, was held 
on October 1, 2018. 

On October 2, 2018, YPF received notice of the decision adopted by the judge in charge of Oil Combustibles S.A.’s bankruptcy proceedings, which 
awarded  the  industrial  assets  of  the  bankrupt  company  to  YPF  and  DAPSA,  pursuant  to  the  local  and  international  bidding  process  carried  out  in 
connection with the sale of Oil Combustibles S.A.’s assets. 

The total price of the transaction amounted to US$ 85 million, which was paid on November 2, 2018. From such amount, US$ 63 million correspond to 
net assets acquired by YPF. These, especially the docks and fuel storage tanks located in the Paraná River fluvial terminal, will allow the expansion of 
YPF’s logistics capacity for actual and future business. 

YPF requested the unavailability of the funds, which will remain deposited in the judicial account at the order of the court until the conveyance of title 
and registration of the real estate acquired in favor of YPF. 

Additionally,  on  November 6,  2018,  Division  D  of  the  Argentine  Court  of  Appeals  rejected  the  appeal  filed  by  some  of  the  former  Oil  shareholders 
which challenged the award in favor of YPF and DAPSA under the bidding process described herein. 

The acquisition of these assets qualified as a business combination under IFRS 3. 

The following table resumes consideration and fair value of the acquired assets and the liabilities assumed on the acquisition date:

Agreement for the exploitation of the Aguada Pichana and Aguada de Castro Areas

Once the agreements have been finalized and the corresponding conditions have been fulfilled (see Note 29.b), YPF’s interest are as follows: 

(i)

In the APE area, the interest of YPF is 22.50% (which implied the sale of a 4.77% stake); 

(ii)

In the APO area, the interest of YPF is 30% (which implied the purchase of a 2.73% stake); 

(iii)

In the ACA area, the interest of YPF is 30% (which implied the sale of a 20% stake). 

Consequently, the Group has recorded a profit of 1,167 included in the item “Other net operating results”.

As part of the acquisition by Pampa Energía S.A. (“PEPASA”) of the total shares of Petrobras Participaciones S.L., which held 67.2% of the capital and 
voting rights of Petrobras Argentina S.A. (“PESA”), YPF and PEPASA entered into an agreement subject to certain conditions precedent under which, 
once  the  acquisition  by  PEPASA  of  shareholding  control  of  PESA  had  been  completed,  PESA  transferred  to  YPF  its  interest  in  the  operating 
concessions  of  two  areas  located  in  the  Neuquén  basin  with  production  and  high  potential  for  gas  development  (of  the  tight  and  shale  type),  to  be 
operated by YPF, in the percentages detailed below: (i) 33.33% participation in the Río Neuquén area, located in the Province of Neuquén and in the 
Province of Río Negro; and (ii) 80% participation in the Aguada de la Arena area, located in the Province of Neuquén. 

In  order  to  implement  this  agreement,  PEPASA  and  YPF  signed  a  Framework  Agreement  for  the  Financing  and  Acquisition  of  Units  and  a  Loan 
Agreement  under  which  YPF,  on  July 25,  2016,  granted  PEPASA  a  guaranteed  loan  for  the  Indirect  acquisition  of  the  aforementioned  areas  in  the 
amount of US$ 140 million, equivalent to the acquisition price of the aforementioned units, which does not differ from the fair value of the participation 
in said areas. 

On October 14, 2016, the assignment of the interest in the operating concessions between YPF and PESA was consummated, as follows: (i) an interest 
of  33.33%  in  the  Río  Neuquén  area  for  the  sum  of US$  72 million; and  (ii) an  interest of  80%  in the Aguada  de  la  Arena area, for  the  sum  of  US$ 
68 million. 

On February 23, 2017, YPF and Petrouruguay S.A. subscribed the definitive agreement for the assignment in favor of YPF of 20% of the interest in the 
Aguada de la Arena area for US$ 18 million. Thus, YPF increased its participation to 100% in the aforementioned area. 

On March 31, 2017, YPF cancelled, 33.33% of its participation in the Río Neuquén area and 80% of its participation in the Aguada de la Arena area 
through a payment in kind pursuant to an assignment in favor of PESA of its contractual position under the loan contract with PEPASA. 

On September 5,  2018 the Province of  Neuquén issued Decree No. 1401/18 which authorized the  assignment  of 33.33% of the Rio Neuquén area in

FINANCIAL RISK MANAGEMENT 

The Group’s activities expose it to a variety of financial risks: market risk (including foreign currency risk, interest rate risk, and price risks), credit risk 
and liquidity risk. Within the Group, risk management functions are conducted in relation to financial risks associated to financial instruments to which 
the Group is exposed during a certain period or as of a specific date. 

This section provides a description of the principal risks that could have a material adverse effect on the Group’s strategy in each operations center, 
performance,  results  of  operations  and  financial  condition.  The  risks  facing  the  businesses,  set  out  below,  do  not  appear  in  any  particular  order  of 
potential materiality or probability of occurrence. 

The sensitivity analysis of market risks included below are based on a change in one factor while holding all other factors constant. In practice this is 
unlikely to occur, and changes in some of the factors may be correlated, for example, changes in interest rate and changes in foreign currency rates. 

This sensitivity analysis provides only a  limited, point-in-time view. The actual  impact on the Group’s financial instruments may differ significantly 
from the impact shown in the sensitivity analysis.

FINANCIAL RISK MANAGEMENT (Cont.) 

• Market Risk management

The market risk to which the Group is exposed is the possibility that the valuation of the Group’s financial assets or financial liabilities as well as certain 
expected cash flows may be adversely affected by changes in interest rates, exchange rates or certain other price variables. 

The following is a description of these risks as well as a detail of the extent to which the Group is exposed and a sensitivity analysis of possible changes 
in each of the relevant market variables. 

Exchange Rate Risk 

The value of financial assets and liabilities denominated in a currency different from the Company’s functional currency is subject to variations resulting 
from fluctuations in exchange rates. Since YPF’s functional currency is the U.S. dollar, the currency that generates the greatest exposure is the Peso (the 
Argentine legal currency). 

The Group does not use derivatives as a hedge against exchange rate fluctuations. 

Otherwise,  according  to  the  Company’s  functional  currency,  and  considering  the  currency  exchange  process,  the  fluctuations  in  the  exchange  rate 
related to the financial assets and liabilities’ value in Pesos do not have any effect in the Other comprehensive income in Shareholders’ equity.

The  following  table  provides  a  breakdown  of  the  effect  a  variation  of  10%  in  the  prevailing  exchange  rates  on  the  Group’s  net  income,  taking  into 
consideration the exposure of financial assets and liabilities denominated in Pesos as of December 31, 2018:

The Group is exposed to risks associated with fluctuations in interest rates on loans and investments. Changes in interest rates may affect the interest 
income or loss derived from financial assets and liabilities tied to a variable interest rate. Additionally, the fair value of financial assets and liabilities 
that accrue interests based on fixed interest rates may also be affected. 

The table below provides information about the financial assets and liabilities as of December 31, 2018 that accrues interest considering the applicable

Includes temporary investments, loans with related parties and trade receivables with interest-bearing payment agreements. It does not include the 
rest of the trade receivables that are mostly non-interest bearing. 
Includes only financial loans. Does not include accounts payable, which mostly do not accrue interest. 
Includes principal and interest. 

The  variable  rate  financial  loans  represent  18%  of  the  total  loans  as  of  December 31,  2018,  and  include  NO,  pre-financing  of  exports,  financing  of 
imports and financial loans with local and international entities. The portion of the loan, which accrues variable interest rate, is mainly exposed to the 
fluctuations  in  LIBOR  and  BADLAR.  Approximately  26,277  accrues  variable  interest  of  BADLAR  plus  a  spread  between  0%  and  10%  and  30,879 
accrues variable interest of LIBOR plus a spread between 1.25% and 4%. 

Approximately 86% (289,569) of the total of the financial loans of the Group is denominated in U.S. dollars, 3% (11,563) is in Swiss francs and the 
remainder is mainly in Pesos, as of December 31, 2018.

FINANCIAL RISK MANAGEMENT (Cont.) 

Financial assets mainly include, in addition to trade receivables, which have low exposure to interest rate risk, bank deposits, fixed-interest deposits and 
investments in mutual funds such as money market or short-term fixed interest rate instruments. 

The Group’s strategy to hedge interest rate risk is based on investing funds at a variable interest rate, which partially offset financial loans at a variable 
interest rate, as well as on maintaining relatively low percentages of debt at a variable interest rate. 

The Group does not usually use derivative financial instruments to hedge the risks associated with interest rates. 

The table below shows the estimated impact on consolidated statement of comprehensive income that an increase or decrease of 100 basis points in the 
interest rate would have.

Price Risks 

The Group is exposed to the own price risk for investments in financial instruments (public securities and mutual funds), which were classified in the 
statement of financial position as “at fair value through profit or loss”. The Group continuously monitors the change in these investments for significant 
movements. 

As of December 31, 2018, the aggregate value of financial assets at fair value through profit or loss amounts to 18,733. 

The following table shows the effect that a 10% variation in the prices of investments in financial instruments would have on the Group’s results as of 
December 31, 2018:

The Group does not use derivative financial instruments to hedge the risks associated with the fluctuation of the price of commodities as well as the risk 
inherent to investments in public securities and mutual funds. 

Likewise, although not considered a financial risk, until recently, the Group was not significantly exposed to commodity price risks, as a result, among 
other reasons, of the existing regulatory, economic and government policies in force that determined that local prices charged for gasoline, diesel and 
other fuels were not affected in the short-term by fluctuations in the price of such products in international and regional markets. That is, there was a gap 
between  domestic  market  prices  and  international  market  prices,  which  was  evident  in  certain  periods  with  price  variations  in  directions  (or  values) 
substantially different from those observed in the international market. 

However, since the second semester of 2016 a local process was initiated to achieve an orderly transition towards international prices, which implied a 
gradual decrease in the sales prices of local crude oils (Medanito and Escalante). In the same way, Producers and Refiners entered into new agreements 
for the above mentioned transition for the purpose of achieving parity with international markets. 

The negative domestic macroeconomic conditions that prevailed in 2018 represented a challenge for the new market model, which prevented the full 
deployment of such conditions over the year. Also, see Note 2.c. 

In consequence, the aforementioned price risk exposure has changed and it will depend on the capacity of the Group to transfer to its fuel prices on the 
local market, the variations in international prices as well as the possibility of adapting its costs to such changes.

FINANCIAL RISK MANAGEMENT (Cont.) 

•

Liquidity Risk management

Liquidity risk is associated with the possibility of a mismatch between the need of funds to meet short, medium or long-term obligations. 

As mentioned in previous paragraphs, the Group intends to align the maturity profile of its financial debt to be related to its ability to generate enough 
cash  flows  for  its  cancellation,  as  well  as  to  finance  the  projected  expenditures  for  each  year.  As  of  December 31,  2018  the  availability  of  liquidity 
reached 46,028, considering cash of 6,678 and other liquid financial assets of 39,350. Uncommitted bank credit lines together with the capital market 
constitute  an  important  source  of  funding.  Likewise,  YPF  has  the  ability  to  issue  additional  debt  under  the  negotiable  obligations  global  program 
originally approved by the Shareholders meeting in 2008 expanded in September 2012, in April 2013, in February 2015, in April 2016 and extended in 
2017 

The following table sets forth the maturity dates of the Group’s financial liabilities as of December 2018:

The amounts disclosed are the contractual, undiscounted cash flows associated to the financial liabilities given that they do not differ significantly 
from their face values 

Most of the Group’s loans contain usual covenants for contracts of this nature. Approximately 56% of the outstanding loans as of December 31, 2018 
are subject to financial covenants related to the average ratio and debt service coverage ratio. 

Under the terms of the loan agreements and NO, if the Group breached a covenant or if it could not remedy it within the stipulated period, it would 
default,  a  situation  that  would  limit  its  liquidity  and,  given  that  the  majority  of  its  loans  contain  cross  default  provisions,  it  could  result  in  an  early 
enforceability of its obligations. 

•

Credit Risk management

Credit risk is defined as the possibility of a third party not complying with its contractual obligations, thus negatively affecting results of operations of 
the Group. 

Credit risk in the Group is measured and controlled on an individual customer basis. The Group has its own systems to conduct a permanent evaluation 
of credit performance of all of its debtors, and the determination of risk limits with respect to third parties, in line with best practices using for such end 
internal customer records and external data sources. 

Financial instruments that potentially expose the Group to a credit concentration risk consist primarily of cash and cash equivalents, trade receivables 
and other receivables. The Group invests excess cash primarily in high liquid investments with financial institutions with a strong credit rating both in 
Argentina  and  abroad.  In  the  normal  course  of  business  and  based  on  ongoing  credit  evaluations  to  its  customers,  the  Group  provides  credit  to  its 
customers and certain related parties. 

Likewise, the Group accounts for doubtful trade losses in the statement of comprehensive income, based on specific information regarding its clients. 

Provisions for doubtful accounts are measured by the criteria mentioned in Note 2.b.18.

Considering the maximum exposure to the risk of the Other financial assets based on the concentration of the counterparties, credit with the National 
Government and direct agencies accounts for approximately 34% (36,979), while the Group’s remaining debtors are diversified. 

Following is the breakdown of the financial assets past due as of December 31, 2018: 

Less than three months past due
Between three and six months past due

At such date, the provision for doubtful trade receivables amounted to 2,776 and the provisions for other doubtful receivables amounted to 619. These 
provisions are the Group’s best estimate of the losses incurred in relation with accounts receivables. 

Guarantee Policy 

As  collateral  of  the  credit  limits  granted  to  customers,  the  Group  receives  several  types  of  guarantees  from  its  customers.  In  the  gas  stations  and 
distributors market, where generally long-term relationships with customers are established, mortgages prevail. For foreign customers, joint and several 
bonds  from  their  parent  companies  prevail.  In  the  industrial  and  transport  market,  bank  guarantees  prevail.  To  a  lesser  extent,  the  Group  has  also 
obtained other guarantees such as credit insurances, surety bonds, guarantee customer – supplier, and car pledges, among others. 

The Group has effective guarantees granted by third parties for a total amount of 24,377, 10,789 and 9,300 as of December 31, 2018, 2017 and 2016, 
respectively. 

During the fiscal year ended December 31, 2018, the Group did not execute guarantees. During the fiscal years ended December 31, 2017 and 2016, the 
Group executed guarantees received for an amount of 2 and 1, respectively.

SEGMENT INFORMATION 

The different segments in which the Group is organized take into consideration the different activities from which the Group obtains income and incurs 
expenses. The aforementioned organizational structure is based on the way in which the highest decision-making authority analyzes the main financial 
and operating magnitudes for making decisions about resource allocation and performance assessment also considering the Group’s business strategy. 

•

Upstream 

The Upstream segment carries out all activities relating to the exploration, development and production of oil and natural gas. 

Revenue is generated from (i) the sale of produced crude oil to the Downstream segment and, marginally, from its sale to third parties; (ii) the sale 
of produced gas to the Gas and Power segment. 

• Gas and Power 

The Gas and Power segment generates its revenue from the development of activities relating to: (i) the natural gas commercialization to third 
parties  and  the  Downstream  segment,  (ii) the  commercial  and  technical  operation  of  LNG  regasification  terminals  in  Bahía  Blanca  (until 
October 31, 2018) and Escobar, by hiring two regasification vessels, and (iii) the natural gas distribution. 

Additionally, for the years ended December 31, 2017 and 2016, it included revenues derived from the generation of conventional and renewable 
electricity corresponding to YPF EE. See Note 3. 

In addition to the proceeds derived from the sale of natural gas to third parties and the intersegment, which is then recognized as a “purchase” to 
the Upstream segment, and including Stimulus Plan for Natural Gas production in force (see Note 30.g), Gas and Power accrues a fee in its favor 
with the Upstream segment to carry out such commercialization. 

•

Downstream 

The Downstream segment develops activities relating to: (i) crude oil refining and petrochemical production, (ii) commercialization of refined and 
petrochemical  products  obtained  from  such  processes,  (iii) logistics  related  to  the  transportation  of  crude  oil  and  gas  to  refineries  and  the 
transportation and distribution of refined and petrochemical products to be marketed in the different sales channels. 

It obtains its income from the marketing mentioned in item (ii) above, which is developed through the Retail, Industry, Agro, LPG, Chemicals and 
Lubricants and Specialties businesses. 

It incurs in all expenses relating to the aforementioned activities, including the purchase of crude oil from the Upstream segment and third parties 
and the natural gas to be consumed in the refinery and petrochemical industrial complexes from the Gas and Power segment. 

•

Central Administration and Others 

It  covers  other  activities,  not  falling  into  the  aforementioned  categories,  mainly  including  corporate  administrative  expenses  and  assets  and 
construction activities. 

Sales between business segments were made at internal transfer prices established by the Group, which generally seek to approximate market prices. 

Operating profit and assets for each segment have been determined after consolidation adjustments.

Fair value measurements 

IFRS 9 defines the fair value of a financial instrument as the amount for which an asset could be exchanged, or a financial liability settled, between 
knowledgeable, independent parties in an arm’s length transaction. All financial instruments recognized at fair value are allocated to one of the valuation 
hierarchy levels of IFRS 7. This valuation hierarchy provides for three levels. 

In the case of Level 1, valuation is based on unadjusted quoted prices in active markets for identical financial assets or liabilities that the Group can refer 
to at the end of the period. A market is deemed active if transactions take place with sufficient frequency and in sufficient quantity for price information 
to be available on an ongoing basis. Since a quoted price in an active market is the most reliable indicator of fair value, this should always be used if 
available. Financial instruments assigned by the Group to this level comprise investments in listed mutual funds and public securities. 

In  the  case  of  Level 2,  fair  value  is  determined  by  using  valuation  methods  based  on  inputs  directly  or  indirectly  observable  in  the  market.  If  the 
financial instrument concerned has a fixed contract period, the inputs used for valuation must be observable for the whole of this period. The Group has 
not valued financial instruments under this category. 

In the case of Level 3, the Group uses valuation techniques not based on inputs observable in the market. This is only permissible insofar as no market 
data  are  available.  The  inputs used  reflect the Group’s assumptions regarding the  factors,  which  market  players would  consider  in  their pricing. The 
Group uses the best available information for this, including internal company data. The Group has not valued financial instruments under this category. 

YPF’s  Corporative  Finance  Division  has  a  team  in  place  in  charge  of  the  valuation  of  financial  instruments  required  to  be  reported  in  the  financial 
statements, including the fair value of Level 3 instruments. The team directly reports to the CFO. The CFO and the valuation team discuss the valuation 
methods and results upon the acquisition of a financial instrument and, if necessary, on a quarterly basis, in line with the Group’s quarterly reports.

The Group has no financial liabilities measured at fair value through profit or loss. 

The Group’s policy is to acknowledge transfers among the several categories of valuation hierarchies when occurred, or when there are changes in the 
prevailing  circumstances  requiring  such  transfer.  During  the  years  ended  December 31,  2018,  2017  and  2016,  there  were  no  transfers  between  the 
different hierarchies used to determine the fair value of the Group’s financial instruments. 

Fair value of financial assets and financial liabilities measured at amortized cost 

The estimated fair value of loans, considering unadjusted listed prices (Level 1) for NO and interest rates offered to the Group (Level 3) for the other 
financial loans remaining, amounted to 293,972, 200,264 and 157,133 as of December 31, 2018, 2017 and 2016, respectively. 

The fair value of other receivables, trade receivables, cash and cash equivalents, accounts payable and other liabilities do not differ significantly from 
their book value.

YPF SOCIEDAD ANONIMA
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2018, 2017 AND 2016

14. PROVISIONS (Cont.) 

The Group is part to a number of labor, commercial, civil, tax, criminal, environmental, customs and administrative proceedings that, either alone or in 
combination  with  other proceedings, could, if resolved in whole or in part adversely against it,  result in the imposition of  material costs, judgments, 
fines  or  other  losses.  While  the  Group  believes  that  such  risks  have  been  provisioned  appropriately  based  on  the  opinions  and  advice  of  our  legal 
advisors  and  in  accordance  with  applicable  accounting  standards,  certain  loss  contingencies  are  subject  to  change  as  new  information  develops  and 
results  of the presented  evidence  are  obtained, among other factors. It  is possible  that losses resulting  from  such  risks, if proceedings  are  decided  in 
whole or in part adversely to the Group, could significantly exceed the recorded provisions. 

Additionally, due to its operations, the Group is subject to various laws and regulations relating to the protection of the environment. These laws and 
regulations  may  impose,  among  other  things,  liability  on  companies  for  the  cost  of  pollution  cleanup  and  environmental  damages  resulting  from 
operations. Management believes that the Group’s operations are in substantial compliance with laws and regulations currently in force relating to the 
protection of the environment as such laws have historically been interpreted and enforced. 

However, the Group is periodically conducting new studies to increase its knowledge concerning the environmental situation in certain geographic areas 
where the Group operates in Argentina, in order to establish their status, causes and necessary remediation and, based on the aging of the environmental 
issue, to analyze the possible responsibility of the Argentine Government, in accordance with the contingencies assumed by the Argentine Government 
for which YPF has the right of indemnity for liabilities existing as of December 31, 1990. Until these studies are completed and evaluated, the Group 
cannot estimate what additional costs, if any, will be required. However, it is possible that other work, including provisional remedial measures, may be 
required. 

14.a) Provision for lawsuits and contingencies 

The Group has accrued pending lawsuits, claims and contingencies, which are probable and can be reasonably estimated. The most significant pending 
lawsuits and contingencies accrued are described in the following paragraphs. 

14.a.1) Liabilities and contingencies assumed by the Argentine Government before 1990 

Under  YPF’s  Privatization  Law,  the  Argentine  Government  took  over  certain  obligations  of  the  predecessor  company  as  of  December 31,  1990.  In 
certain lawsuits related to events or acts that took place before December 31, 1990, YPF has been required to make advance payments established in 
certain  judicial  decisions.  YPF  has  the  right  to  be  reimbursed  for  these  payments  by  the  Argentine  Government  pursuant  to  the  above-mentioned 
indemnity. 

14.a.2) Claims arising from restrictions in the natural gas market 

•

DOP Claims 

Pursuant  to  Resolution  No. 265/2004  of  the  Secretariat  of  Energy,  the  Argentine  Government  created  a  program  of  useful  cutbacks  of  natural  gas 
exports  and  their  associated  transportation  services.  Such  program  was  initially  implemented  by  means  of  Regulation  No. 27/2004  of  the  Under-
Secretariat  of  Fuels,  which  was  subsequently  substituted  by  the  Program  of  Rationalization  of  Gas  Exports  and  Use  of  Transportation  Capacity  (the 
“Program”)  approved  by  Resolution  No. 659/2004  of  the  Secretariat  of  Energy.  Additionally,  Resolution  No. 752/2005 provided  that  industrial  users 
and  thermal  generators  (which  according  to  this  resolution  will  have  to  request  volumes  of  gas  directly  from  the  producers)  could  also  acquire  the 
natural  gas  from  the  cutbacks  on  natural  gas  exports  through  the  Permanent  Additional  Injection  mechanism  created  by  this  resolution.  Through  the 
Program and/or the Permanent Additional Injection, the Argentine Government requires natural gas exporting producers to deliver additional volumes to 
the domestic market in order to satisfy natural gas demand of certain consumers in the Argentine market (“Additional Injection Requirements”). Such 
additional volumes are not contractually committed by YPF, which is thus forced to affect natural gas exports, which execution has been conditioned. 
The  mechanisms  established  by  the  Resolutions  No. 659/2004  and  752/2005  have  been  adapted  by  Secretariat  of  Energy  Resolution  No. 599/2007, 
which modifies the conditions for the imposition of the requirements, depending on whether the producers have signed the proposed agreement, ratified 
by such resolution, between the Secretariat of Energy and the producers.

YPF SOCIEDAD ANONIMA
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2018, 2017 AND 2016

14. PROVISIONS (Cont.) 

Resolution No. 1410/2010 of the ENARGAS also approved the “Procedure for Applications, Confirmations and Gas Control” which sets new rules for 
natural gas dispatch applicable to all participants in the natural gas industry, imposing new and more severe regulations to the producers’ availability of 
natural  gas.  Additionally,  the  Argentine  Government,  through  instructions  made  using  different  procedures,  has  ordered  limitations  on  natural  gas 
exports (in conjunction with the Program and the Permanent Additional Injection, named the “Export Administration”). On January 5, 2012, the Official 
Gazette  published  Secretariat  of  Energy  Resolution  No. 172,  which  temporarily  extends  the  rules  and  criteria  established  by  Resolution  No. 599/07, 
until  new  legislation  replaces  the  resolution  previously  mentioned.  This  resolution  was  appealed  on  February 17,  2012  by  filing  a  motion  for 
reconsideration with the Secretariat of Energy. 

Because  of  the  resolutions  mentioned  before,  in  several  occasions  since  2004,  YPF  was  forced  to  suspend,  either  totally  or  partially,  its  natural  gas 
deliveries to some of its export clients, with whom YPF has undertaken firm commitments to deliver natural gas. 

YPF has challenged the Program, the Permanent Additional Injection and the Additional Injection Requirements, established by Secretariat of Energy 
Resolutions No. 599/2007 and 172/2011 and ENARGAS Resolution No. 1410/2010, as arbitrary and illegitimate, and has invoked vis-à-vis the relevant 
clients that the Export Administration constitute a fortuitous case or force majeure event (act of authority) that releases YPF from any liability and/or 
penalty for the failure to deliver the contractual volumes. These clients have rejected the force majeure argument invoked by YPF, and some of them 
have demanded the payment of indemnifications and/or penalties for the failure to comply with firm supply commitments, and/or reserved their rights to 
future claims in such respect. On December 9, 2015, the ENARGAS rejected YPF’s challenge to Resolution No. 1410/2010. YPF did not appeal the 
ENARGAS  resolution  that  dismissed  the  presented  challenge.  On  June 29,  2018  ENARGAS  Resolution  No. 124/2018  was  published,  approving  the 
restated text of the internal regulations of dispatch centers applicable as from June 30, 2018 and derogates ENARGAS Resolution No. 1410/10. 

Costs from contractual penalties arising from the failure to deliver natural gas until December 31, 2018, have been charged to provision to the extent 
that such costs are probable and can be reasonably estimated.

AES Uruguaiana Emprendimentos S.A. (“AESU”) and Transportadora de Gas del Mercosur S.A. (“TGM”) 

On June 25, 2008, AESU claimed damages in a total amount of US$ 28.1 million for natural gas “deliver or pay” penalties for cutbacks accumulated 
from September 16, 2007 until June 25, 2008, and also claimed an additional amount of US$ 2.7 million for natural gas “deliver or pay” penalties for 
cutbacks accumulated from January 18, 2006 until December 1, 2006. YPF has rejected both claims. On September 15, 2008, AESU notified YPF that it 
would no longer be complying with its obligations, alleging late payments and non-compliance by YPF. YPF rejected the arguments of this notification. 
On  December 4,  2008,  YPF  notified  AESU  that,  having  ceased  the  force  majeure  conditions  pursuant  to  the  contract  in  force;  it  would  suspend  its 
delivery  commitments,  due  to  repeated  breaches  of  AESU  obligations.  AESU  has  rejected  this  notification.  On  December 30,  2008,  AESU  rejected 
YPF’s right to suspend its natural gas deliveries. On March 20, 2009, AESU formally notified YPF of the termination of the contract.     On April 6, 
2009, YPF promoted an arbitration process at the International Chamber of Commerce (“ICC”) against AESU, Companhía do Gas do Estado do Río 
Grande do Sul (“SULGAS”) and Transportadora de Gas del Mercosur S.A. (“TGM”). On the same date, YPF was notified by the ICC of an arbitration 
process initiated by AESU and SULGAS against YPF in which they claimed, among other matters considered inadmissible by YPF, consequential loss, 
AESU’s plant dismantling costs and the payment of DOP penalties mentioned above, all of which totaled approximately US$ 1,052 million. 

Additionally, YPF was notified of the arbitration process brought by TGM at the ICC, claiming from YPF the payment of approximately US$ 10 million 
plus interest up to the date of effective payment, in connection with the payment of invoices related to the Transportation Gas Contract entered into in 
September 1998 between YPF and TGM, associated with the aforementioned exportation of natural gas contract signed with AESU.

14. PROVISIONS (Cont.) 

On April 8, 2009, YPF requested that this claim be rejected and counterclaimed for the termination of the natural gas transportation contract based on its 
termination rights upon the termination by AESU and SULGAS of the related natural gas export contract. In turn, YPF initiated an arbitration process at 
the ICC against TGM, among others. YPF received the reply to the complaint from TGM, which requested the full rejection of YPF’s claims and filed a 
counterclaim against YPF asking the Arbitration Tribunal to require YPF to compensate TGM for all present and future damages suffered by TGM due 
to the termination of the Transportation Gas Contract and the Memorandum of Agreement dated on October 2, 1998, through which YPF undertook to 
pay irrevocable non-capital contributions to TGM in return for the Uruguayana Project pipeline expansion, and to require AESU and SULGAS (in the 
case the Arbitration Tribunal finds that the termination of the Gas Contract occurred due to the failure of AESU or SULGAS) to indemnify all damages 
caused by such termination to TGM jointly and severally. Additionally, on July 10, 2009, TGM increased the amount of its claim to US$ 17 million and 
claimed an additional amount of approximately US$ 366 million for loss of profits, which were considered inadmissible with respect to YPF, based on 
the foregoing the amendment to the complaint was answered rejecting the grounds alleged by TGM. 

On  April 6,  2011,  the  Arbitration  Tribunal  appointed  in  the  “YPF  vs.  AESU”  arbitration  decided  to  sustain  YPF’s  motion,  and  determined  the 
consolidation  of  all  the  related  arbitrations  (“AESU  vs.  YPF”,  “TGM  vs.  YPF”  and  “YPF  vs.  AESU”)  in  the  “YPF  vs.  AESU”  arbitration. 
Consequently, AESU and TGM desisted from and abandoned their respective arbitrations, and all the matters claimed in the three proceedings are to be 
resolved in the “YPF vs. AESU” arbitration. 

On January 10, 2014, YPF was served with the complaint for damages filed by AESU with the Arbitration Tribunal claiming a total amount of US$ 
815.5 million and also with the complaint for damages filed by TGM with the Arbitration Tribunal claiming a total amount of US$ 362.6 million, which 
were rejected by YPF. 

As a result of the legal and commercial complexities of the dispute between YPF, AESU and SULGAS, as well as the existence of litigation rights in 
different  jurisdictions  around  the  world  (including  the  Republic  of  Argentina,  the  Republic  of  Uruguay  and  the  United  States  of  America),  on 
December 30, 2016, these companies executed an agreement under which YPF undertook to pay a total of US$ 60 million for which, without admitting 
facts  or  rights,  they  waived  all  claims  that  as  of  the  date  they  had  or  could  reciprocally  have,  with  the  exception,  in  the  case  of  YPF,  of  the  nullity 
remedies filed against the arbitral awards that remain in effect. The payment was made on January 10, 2017. 

Moreover, on December 4, 2017, YPF entered into a settlement agreement with TGM terminating all existing claims between the parties, under which 
YPF agreed to pay TGM the sum of US$ 114 million in compensation as total and final payment of all the arbitration and legal actions of TGM (US$ 
107 million  in  an  initial  payment  on  January 2,  2018  and  the  balance  of  US$  7 million  in  7  annual  installments  of  US$  1 million  each,  the  first  one 
maturing on February 1, 2018 and the rest on the same date of the following years). In addition, YPF committed to pay TGM the sum of US$ 13 million 
(in 7 annual installments of US$ 1.86 million each, with the same maturity date as the compensation balance) as payment on account of an interruptible 
exportation  transport  contract  to  be  entered  into  by  the  parties  and  effective  until  2027.  This  settlement  agreement  implied  the  withdrawal  of  the 
proceedings brought by YPF to obtain the declaration of the annulment of the Final Award of Damages and of the resources filed by TGM to obtain the 
revocation of the ruling of Division IV of the Federal Contentious Administrative Court of Appeals, which ordered the annulment of the Responsibility 
Award.  Both  the initial  payment  for  US$ 107 million and the first installments for US$ 1 million  and  US$  1.86 million were made on  the stipulated 
dates.

Transportadora de Gas del Norte S.A. (“TGN”) 

On April 8, 2009, YPF filed a complaint against TGN with ENARGAS, seeking the termination of the natural gas transportation contract with TGN in 
connection with the natural gas export contract entered into with AESU and other parties. The termination of the contract with that company is based on: 
(a) the impossibility of YPF to receive the service and of TGN to render the transportation service, due to (i) the termination of the natural gas contract 
with SULGAS and AESU and (ii) the legal impossibility of assigning the transportation contract to other shippers because of the regulations in effect, 
(b) the legal impossibility of TGN to render the transportation service on a firm basis because of certain changes in law in effect since 2004, and (c) the 
“Teoría de la Imprevisión” available under Argentine law, when extraordinary events render a party’s obligations excessively burdensome. As of the 
date of these financial statements, this complaint has not been resolved.

14. PROVISIONS (Cont.) 

In the complaint, TGN claimed the compliance with the contract and payment of unpaid invoices from February 20, 2007 until March 20, 2009 for a 
total of US$ 30 million. TGN then amended the complained and claimed the payment of unpaid invoices (i) from April 20, 2009 until June 20, 2010 for 
a  total  of  US$  31 million,  (ii) from  July 20,  2010  until  November 20,  2010  for  a  total  of  US$  10 million,  and  (iii) from  December 6,  2010  until 
January 4, 2011 for a total of US$ 3 million. 

Additionally, TGN notified YPF of the rescission of its transportation contract because of YPF’s alleged failure to pay its transportation invoices. YPF 
has responded to these claims, rejecting them based on the legal impossibility of TGN to render the transportation service and in the termination of the 
transportation contract determined by YPF and formalized with a complaint initiated before ENARGAS. 

On  the  trial  for  the  collection  of  bills,  on  September  2011,  YPF  was  notified  of  the  resolution  of  the  Court  of  Appeals  rejecting  YPF’s  claims  and 
declaring that ENARGAS is not the appropriate forum to decide on the matter and giving jurisdiction to the Civil and Commercial Federal courts to 
decide on the claim for the payment of unpaid invoices mentioned above. 

On  September 21,  2016,  evidence  was  submitted  and  the  case  was  opened.  Upon  the  expiration  of  the  trial  period  and  the  submission  of  the  final 
arguments, the case was set for rendering judgment. 

On April 3, 2013, YPF was notified of the complaint for damages brought by TGN, whereby TGN demanded the amount of US$ 142 million from YPF, 
plus interest and legal fees for the termination of the transportation contract. On May 31, 2013, YPF responded to the claim, requesting the dismissal 
thereof. On April 3, 2014, the evidence production period commenced for a 40-day lapse, and the court notified the parties that they would submit a 
copy of evidence offered by them to create an exhibit binder. YPF submitted its plea on June 21, 2017, after the closing of the evidentiary period. 

After both parties’ pleas were submitted, the Lower Court decided it would defer its final judgment until after deciding on the claim brought by TGN to 
litigate in forma pauperis. TGN appealed through separate complaints, which were dismissed by the Court of Appeals in November 2017. On June 21, 
2018, TGN filed for a withdrawal to the waiver it obtained in respect of payment of Court fees and costs, based on the improvement in its financial 
situation during 2018, and paid the Court fees. The Court requested TGN to express the taxable basis on which payment of the Court fees was assessed 
and ordered to notify YPF of this waiver. YPF opposed TGN’s request that each party bears its own legal costs and on November 28, 2018 the court 
decided to dismiss the request for the benefit of litigation without costs and charged TGN with legal costs. TGN appealed such court decision, which as 
of the date of issuance of these financial statements is still pending determination. Without prejudice to this, the main file went on to dictate sentence.

Nación Fideicomisos S.A. (“NAFISA”) 

NAFISA initiated a claim against YPF in relation to payments of applicable fees to Fideicomiso Gas I and Fideicomiso Gas II, respectively, for natural 
gas transportation services to Uruguaiana corresponding to the transportation invoices claimed by TGN. A mediation hearing finished without resulting 
in an agreement, concluding the pre-trial stage. Additionally, on January 12, 2012 and following a mediation process that ended without any agreement, 
NAFISA filed a complaint against YPF, under article 66 of Law No. 24,076, before ENARGAS, claiming the payment of certain transportation charges 
in an approximate amount of 339. On February 8, 2012, YPF answered the claim raising ENARGAS’ lack of jurisdiction, referring to the connection 
with the “TGN vs. YPF” trial, the consolidation in the “TGN vs. YPF” trial and rejecting the claim based on the theory of legal impossibility of TGN to 
provide  the  transportation  services.  On  the  same  date,  a  similar  order  of  consolidation  was also  submitted  in  the  “TGN  vs.  YPF”  trial.  On  April 12, 
2012, ENARGAS resolved in favor of NAFISA. On May 12, 2012, YPF filed an appeal against such resolution to the National Court of Appeals in the 
Federal Contentious Administrative. On November 11, 2013, the court dismissed the direct appeal filed by YPF. In turn, on November 19, 2013, YPF 
submitted  an  ordinary  appeal  before the CSJN  and  on November 27, an extraordinary  appeal  was lodged before  the  CSJN.  The  ordinary appeal was 
granted and YPF timely filed the grounds of such appeal. On September 29, 2015, the CSJN upheld YPF’s appeal and reversed the resolution issued by 
the Federal Contentious Administrative Court – Division IV – because ENARGAS lacks legal capacity to participate in these proceedings, as the parties 
are not subject to the Gas Law. The administrative instance for this case has been concluded, following the exhaustion of the administrative proceedings 
before ENARGAS. NAFISA has failed to file a complaint in court to date.

14.a.3) Claims within the jurisdiction of the National Antitrust Protection Board CNDC 

The  Users  and  Consumers  Association  claimed  (originally  against  Repsol  YPF  S.A.  before  extending  its  claim  to  YPF)  the  reimbursement  of  the 
overprice  allegedly  charged  to  bottled  LPG  consumers  between  1993  and  1997  and  1997  to  2001.  In  the  response  to  the  claim,  YPF  requested  the 
application of the statute of limitations since at the date of the extension of the claim, the two-year limit had already elapsed. 

On December 28, 2015, the lower court rendered judgment admitting the claim seeking compensation for the term between 1993 and 1997 filed by the 
Users  and  Consumers  Association  against  YPF  and  ordered  the  Company  to  transfer  the  amount  of  98  plus  interest  (to  be  estimated  by  the  expert 
witness in the settlement period) to the Secretariat of Energy, to be allocated to the trust fund created by Law No. 26,020. 

The judgment dismissed the claim for the items corresponding to the period between 1997 and 2001, considering the dominant position of YPF in the 
domestic bulk LPG market had not been sufficiently proved. The Company appealed the decision of the lower court. 

Furthermore,  the  judgment  dismissed  the  complaint  against  Repsol  S.A.,  as  Repsol  YPF  S.A.  had  no  equity  interest  in  YPF,  nor  any  other  kind  of 
relation with YPF from 1993 to 1997, the period in which the plaintiffs claim YPF abused its dominant position. 

The Company appealed the judgment, which was admitted with staying effect. The Users and Consumers Association also appealed the judgment and 
both parties filed their respective appellate briefs. 

On  December 7,  2017,  the  Company  was  served  with  notice  of  the  judgment  of  the  Court  of  Appeals  whereby:  (i) confirming  the  claims  for 
compensation for the 1993 to 1997 period; (ii) extending the claim of Users and Consumers Association for the period 1997 to December 1999 for the 
item “equity transfer of consumers to producers for the higher cost of liquefied petroleum gas”, postponing the liquidation of the item for the execution 
stage of the judgment (the Court of Appeals did not set this amount); and (iii) partially granting the appeal filed by the defendant with respect to the item 
“damage  caused  by  lower  or  different  energy  consumption  due  to  the  higher  cost  of  Liquefied  Petroleum  Gas”.  The  Company  has  analyzed  the 
economic impact of the judgment of the Court of Appeals, which by extending the item of paragraph (i) above for the period 1997-1999, would increase 
the duly estimated amount. It should be noted that the ruling confirmed by the Court of Appeals does not order YPF to pay the claimant the ultimately 
settled  amount,  but  rather  to  transfer  such  funds  to  the  National  Secretariat  of  Energy  for  the  funds  to  be  allocated  to  a  trust  fund  created  by  Law 
No. 26,020,  for  purposes  of  the  expansion  of  the  natural  gas  network  in  areas  with  lower  resources  according  to  the  criteria  established  by  the 
enforcement  authority.  The  enforcement  authority,  within  six  months  from  the  settlement  of  the  judgment  amount,  must  present  the  corresponding 
feasibility studies (Dec. 470/15) together with a work plan, which must begin within six months from the presentation of the feasibility studies. Finally, 
the  Company  has  filed  an  extraordinary  appeal  against  the  judgment  of  the  Court  of  Appeals,  which  has  been  sustained  and  the  court  file  has  been 
submitted to the CSJN. 

14.a.4) Environmental claims: 

•

La Plata 

In  relation  with  the  operation  of  the  refinery  that  YPF  has  in  La  Plata,  there  are  certain  claims  for  compensation  of  individual  damages  purportedly 
caused by the operation of the La Plata refinery and the environmental remediation of the channels adjacent to the mentioned refinery. During 2006, 
YPF  submitted  a  presentation  before  the  Environmental  Secretariat  of  the  Province  of  Buenos  Aires,  which  put  forward  for  consideration  the 
performance of a study for the characterization of environmental associated risks. As previously mentioned, YPF has the right to indemnity for events 
and claims prior to January 1, 1991, according to Law No. 24,145 and Decree No. 546/1993. Besides, there are certain claims that could result in the 
requirement to make additional investments connected with the operations of La Plata refinery.

14. PROVISIONS (Cont.) 

On January 25, 2011, YPF entered into an agreement with the environmental agency of the Government of the Province of Buenos Aires (Organismo 
Provincial para el Desarrollo Sostenible, or “OPDS”), within the scope of the Remediation, Liability and Environmental Risk Control Program, created 
by Resolution No. 88/2010 of the OPDS. Pursuant to the agreement, the parties agreed to jointly perform an eight-year work program in the channels 
adjacent to the La Plata refinery, including characterization and risk assessment studies of the sediments. The agreement provides that, in the case that a 
required remediation action is identified because of the risk assessment studies, the different alternatives and available techniques will be considered, as 
well as the steps needed for the implementation. Dating studies will also be performed pursuant to the agreement, in order to determine responsibilities 
of  the  Argentine  Government  in  accordance  with  its  obligation  to  hold  YPF  harmless  in  accordance  with  the  article  9  of  Law  No. 24,145  of  the 
Privatization  of  YPF.  In  this  context,  YPF,  with  the  agreement  of  OPDS,  has  carried  out  several  studies  and  characterizations  through  specialized 
consultants whose progress has been notified to the provincial body. 

In addition to the above, there are other similar claims made by neighbors of the same locale, alleging environmental and other associated damages. 

• Quilmes 

The  plaintiffs  who  allege  to  be  residents  of  Quilmes,  Province  of  Buenos  Aires,  have  filed  a  lawsuit  in  which  they  have  requested  remediation  of 
environmental damages and also the payment as compensation for alleged personal damages. They base their claim mainly on a fuel leak in the pipeline 
running from La Plata to Dock Sud, currently operated by YPF, which occurred in 1988 as a result of an unlawful act that caused the rupture of the 
polyduct, when YPF was a state-owned company. Fuel would have emerged and become perceptible on November 2002, which resulted in remediation 
works that are being performed by the Company in the affected area, supervised by the environmental authority of the Province of Buenos Aires. The 
Argentine Government has denied any responsibility to indemnify YPF for this matter, and the Company has sued the Argentine Government to obtain a 
declaration of invalidity of such decision. The suit is still pending. 

In addition to the above, YPF was notified of a similar environmental claim made by residents of the same locale, for damages. Such complaint has been 
answered in due course. At present, the case is undergoing the evidentiary stage. 

• Other environmental claims 

In addition to claims discussed above, the Group has other legal claims against it based on similar arguments. In addition, non-judicial claims have been 
initiated against YPF based on similar arguments. In all these cases, considering the information available to date, the estimated time remaining until the 
end of the proceedings, and the results of the additional evidence presented during the continuation of the litigation, the Group has charged to provision 
its best estimate for the objective value of the claims. 

14.a.5) Tax claims 

The  Group  has  received  a  number  of  complaints  from  the  Federal  Administration  of  Public  Income  AFIP  and  the  provincial  and  municipal  tax 
authorities that are not individually significant, and for which the corresponding provision has been granted, based on the best estimate according to the 
information available as of the date of the issuance of these consolidated financial statements. 

14.a.6) Other pending litigation 

During the normal course of its business dealings, the Group has been sued in numerous legal proceedings in labor, civil and commercial courts. The 
management  of  the  Company,  in  consultation  with  its  outside  counsel,  has  established  a  provision  considering  the  best  estimate  for  these  purposes, 
based on the information available as of the date of issuance of these consolidated financial statements, including legal fees and expenses. 

14.b) Provision for environmental expenses and obligations for the abandonment of hydrocarbon wells 

Based on the Group’s current remediation plan, the Group has accrued environmental remediation costs where assessments and/or remedy actions are 
probable and can reasonably be estimated.

For fiscal year ended December 31, 2018, the Group estimated a tax loss carryforward of 57,267. Deferred income tax assets are recognized for tax loss 
carryforwards to the extent their setoff through future taxable profits is probable. Tax loss carryforwards in Argentina expire within 5 years. 

In order to fully realize the deferred income tax asset, the Group will need to generate taxable income. Based upon the level of historical taxable income 
and projections for future over the years in which the deferred income tax are deductible, Management of the Company believes that as of December 31, 
2018 it is probable that the Group will realize all of the deferred income tax assets. 

As of December 31, 2018, Group’s tax loss carryforwards at the expected recovery rate were as follows:

INVESTMENTS IN JOINT OPERATIONS 

The  Group  participates  in  JO  and  other  agreements  that  give  to  the  Group  a  contractually  established  percentage  over  the  rights  of  the  assets  and 
obligations that emerge from the contracts. Interest in such JO have been consolidated line by line on the basis of the mentioned interest over the assets, 
liabilities, income and expenses related to each contract. Interest in JO have been calculated based upon the latest available financial statements as of the 
end of each year, taking into consideration significant subsequent events and transactions as well as management information available. 

The exploration and production JO and other agreements in which YPF participates allocate the hydrocarbon production to each partner based on the 
ownership interest; consequently, such hydrocarbons are commercialized directly by the partners recognizing each of them the corresponding economic 
effects.

SHAREHOLDERS’ EQUITY 

The  Company’s  subscribed  capital  as  of  December 31,  2018,  is  3,923  and  10  own  treasury  shares  represented  by  393,312,793  book-entry  shares  of 
common  stock  and  divided  into  four  classes  of  shares  (A,  B,  C  and  D),  with  a  par  value  of  Pesos  10  and  1  vote  per  share.  These  shares  are  fully 
subscribed, paid-in and authorized for stock exchange listing. 

As  of  December 31,  2018,  there  are  3,764  Class A  outstanding  shares.  As  long  as  any  Class A  share  remains  outstanding,  the  affirmative  vote  of 
Argentine Government is required for: 1) mergers, 2) acquisitions of more than 50% of YPF shares in an agreed or hostile bid, 3) transfers of all the 
YPF’s  production  and  exploration  rights,  4)  the  voluntary  dissolution  of  YPF  or  5)  change  of  corporate  and/or  tax  address  outside  the  Argentine 
Republic. Items 3) and 4) will also require prior approval by the Argentine Congress. 

Until  the  enactment  of  Law  No. 26,741  detailed  in  the  next  paragraphs,  Repsol  S.A.  had  a  participation  in  the  Company,  directly  and  indirectly,  of 
approximately 57.43% shareholding while Petersen Energía S.A.U. and its affiliates exercised significant influence through a 25.46% shareholding of 
YPF’s capital stock. 

Law No. 26,741 enacted on May 4, 2012, changed YPF’s shareholding structure. The mentioned Law declared as national public interest and subject to 
expropriation the Class D Shares of YPF owned by Repsol S.A., its controlled or controlling entities, representing the 51% of YPF’s equity. According 
to  Law  26,741,  achieving  self-sufficiency  in  the  supply  of  hydrocarbons  as  well  as  in  the  exploitation,  industrialization,  transportation  and  sale  of 
hydrocarbons,  is  thereby  declared  of  national  public  interest  and  a  priority  for  Argentina,  with  the  goal  of  guaranteeing  socially  equitable  economic 
development,  the  creation  of  jobs,  the  increase  of  the  competitiveness  of  various  economic  sectors  and  the  equitable  and  sustainable  growth  of  the 
provinces and regions. The shares subject to expropriation were distributed as follows: 51% for the Argentine federal government and 49% for certain 
Argentine Provinces. 

The  General  and  Extraordinary  Shareholders’  Meeting  was  held  on  April 27,  2018  and  approved  the  financial  statements  of  YPF  for  the  fiscal  year 
ended December 31, 2017 and additionally, approved the following resolution in relation to the allocation of profits: a) to allocate the sum of 120 to 
create  a  Reserve for the  purchase of treasury  shares  in  order to give the Board of Directors  the possibility of acquiring treasury shares at the time it 
deems appropriate, and complying, during the execution of the plans, with the commitments assumed and to be assumed by them in the future; b) to 
allocate the sum of 11,020 to create a reserve for investments under the terms of article 70, third paragraph of the LGS; and c) to allocate the sum of 
1,200  to  a  reserve  for  future  dividends,  empowering  the  Board  of  Directors,  until  the  date  of  the  next  General  Shareholders’  Meeting  at  which  the 
financial statements ended as of December 31, 2018 will be dealt with, to determine the time and amount for their distribution, taking into account the 
financial conditions and availability of funds as well as the operating results, investments and other matters that are deemed relevant in the development 
of  the  Company’s  activities,  or  their  allocation  in  accordance  with  the  provisions  set  forth  in  article  224,  second  paragraph,  of  the  LGS  and  other 
applicable regulations. 

On  December 12,  2018,  the  Board  of  Directors  of  the  Company  decided  to  pay  a  dividend  of  3.05  per  share,  which  was  made  available  to  the 
shareholders on December 27, 2018.

ISSUES RELATED TO MAXUS ENTITIES 

27.a) Legal proceedings 

27.a.1) Introduction 

Laws and regulations relating to health and environmental quality in the United States of America affect the majority of the operations of: (a) Maxus 
Energy  Corporation  (“Maxus”)  and  its  subsidiaries  Maxus  International  Energy  Company,  Maxus  (US)  Exploration  Company  and  Gateway  Coal 
Company and (b) Tierra Solutions Inc. (“TS”) (collectively, the “Maxus Entities” or “Debtors”). These laws and regulations set certain aspects of health 
and environmental quality, provide for penalties and other liabilities for the violation of such standards and establish in certain circumstances remedial 
obligations. However, upon the Debtors filing voluntary petitions under Chapter 11 (as define in the following section) of the United States Bankruptcy 
Code (the “Bankruptcy Code”), actions to collect a monetary claim for such liabilities against the Debtors were stayed. 

Maxus and TS could have certain potential liabilities associated with operations of Maxus’ former chemical subsidiary with respect to the health and 
environmental  regulations  mentioned  in  the  previous  paragraph;  the  sole  shareholder  of  both  companies  was  YPF  Holdings.  Nevertheless,  this 
circumstance must be analyzed in the context of the limitations indicated below. 

27.a.2) Reorganization Process under Chapter 11 of the Bankruptcy Code of the United States (hereafter, “Chapter 11”) 

On June 17, 2016, voluntary petitions under Chapter 11 of the Bankruptcy Code were filed with the United States Bankruptcy Court of the District of 
Delaware (hereafter, the “Bankruptcy Court”) by the Debtors, subsidiaries of YPF Holdings. Prior to the Debtors’ bankruptcy filing, the Debtors entered 
into an agreement (the “Agreement”) with YPF, jointly with its subsidiaries YPF Holdings, CLH Holdings Inc., YPF International and YPF Services 
USA Corp (jointly, the “YPF Entities”), subject to Bankruptcy Court Approval, to settle all of the Debtors’ claims against the YPF Entities, including 
any alter ego claims which, in the YPF Entities’ opinion, have no merit. 

The  Agreement  provided  for:  i)  the  granting  of  a  loan  by  YPF  Holdings  for  an  amount  of  up  to  US$  63.1 million  (the  “DIP  Loan”)  to  finance  the 
Debtors’ activities during a year-long bankruptcy case, and ii) a payment of US$ 130 million to the Maxus Entities (“Settlement Payment”) for a release 
of all claims that the Debtors might have against the YPF Entities. 

The  first  hearing  corresponding  to  the  filing  under  Chapter  11  (the  “Filing”)  took  place  on  June 20,  2016.  At  that  hearing,  the  Bankruptcy  Court 
approved, among other things, the Debtors’ motions under the DIP Loan, regarding their day-to-day operations, including the Debtors’ use of the system 
for fund management, administration, payment of salaries and benefits to retired employees. 

On December 29, 2016, the Debtors filed with the Bankruptcy Court a proposed Chapter 11 Plan of Liquidation (the “Plan”) and a statement revealing 
information from the Debtors. The Plan foresaw a US$ 130 million Settlement Payment under the Agreement. The Plan (as filed) provided that if the 
Agreement was approved, portions of the US$ 130 million Settlement Payment would be deposited into (i) a liquidating trust for distribution to creditors 
and  (ii) an  Environmental  Response  Trust  for  use  in  remediation.  Moreover,  if  the  Agreement  were  approved,  the  Debtors’  Plan  would  likely  be 
confirmed and the claims against the YPF Entities, including the alter-ego claims, would be settled and released in exchange for the US$ 130 million 
Settlement Payment. 

The Plan, however, provided for certain contingencies should the Bankruptcy Court not approve the Agreement. In that scenario, the Debtors’ claims 
against  YPF  Entities,  including  the  alter-ego  claims  or  piercing  the  corporate  veil,  would  be  transferred  into  a  liquidating  trust,  which  would  likely 
pursue those claims for the creditors’ benefit.

ISSUES RELATED TO MAXUS ENTITIES (Cont.) 

Subject to certain exceptions under the Bankruptcy Code, effective as of the date of the filing of the Chapter 11 petitions with the Bankruptcy Court, 
most  decisions,  as  well  as  the  issues  related  to  creditors’  claims  and  actions  for  the  collection  of  their  claims  that  arose  prior  to  the  filing  date  are 
automatically stayed (among others, those corresponding to claims against the Maxus Entities at the local court  of New Jersey related to the Passaic 
River litigation, which are explained under 27.a.5.i and 27.a.6 of this note). 

On March 28, 2017, the Maxus Entities and the Creditors Committee submitted an alternative restructuring plan (the “Alternative Plan”) which did not 
include the Agreement with the YPF Entities. 

Under  the  Alternative  Plan,  a  Liquidating  Trust  may  submit  alter  ego  claims  and  any  other  claim  belonging  to  the  insolvent’s  estate  against  the 
Company and the YPF Entities. The liquidating trust would be financed by Occidental Chemical Corporation in its capacity as creditor of the Maxus 
Entities. As YPF did not approve such Alternative Plan and the Alternative Plan did not contemplate the implementation of the  originally submitted 
Agreements, on April 10, 2017 YPF Holdings, Inc. sent a note giving notice that this situation constituted an event of default under the loan granted 
under the Agreement with YPF and the YPF Entities (the “DIP Loan”). By the approval of the financing offered by Occidental under the Alternative 
Plan,  the  Judge  ordered  the  repayment  of  the  outstanding  amounts  (approximately  US$  12.2  million)  under  the  terms  of  the  DIP  Loan,  which  were 
subsequently received. 

On May 22, 2017, the Bankruptcy Court of the Delaware District issued an order confirming the Alternative Plan submitted by the Creditors Committee 
and the Maxus Entities. The effective date of the Alternative Plan was July 14, 2017, as the conditions set forth in Article XII.B of the Alternative Plan 
were met. On July 14, 2017, a liquidating trust was also created, which brought the complaint referred to in 27.a.3 in 2018. 

27.a.3) Maxus Energy Corporation Liquidating Trust (“Liquidating Trust”) Claim 

On  June 14,  2018,  the  Liquidating  Trust  filed  a  lawsuit  against  the  Company,  YPF  Holdings,  CLH  Holdings,  Inc.,  YPF  International  and  other 
companies  non-related  to  YPF,  claiming  alleged  damages  in  an  amount  up  to  US$  14,000 million,  principally  in  connection  with  alleged  claims 
purportedly related to corporate restructuring transactions the Company engaged in several years ago (the “Claim”). The lawsuit was filed before the 
United States Bankruptcy Court for the District of Delaware. 

On October 19, 2018, the Company, together with the other companies of the Group that are part of the Claim, filed a motion requesting dismissal of the 
Claim (“Motion to Dismiss”). 

On November 21, 2018, the Liquidating Trust filed its objection to the Motion to Dismiss filed by the Company together with the other companies of 
the Group that are part of the Claim, and to the one filed by the companies not related to YPF and which are part of the Claim. 

On December 10, 2018, the Company, together with the other companies of the Group that are part of the Claim, exercised their right of reply regarding 
the presentation made by the Liquidating Trust 

On January 22, 2019, the hearing regarding the Motion to Dismiss was held in the Bankruptcy Court. 

On  February 15,  2019,  the  Bankruptcy  Court  ordered  the  dismissal  of  the  Motions  to  Dismiss  filed  by  the  Company,  together  with  the  other  Group 
companies and the other defendant companies not related to YPF. 

On  March 1,  2019,  the  Company,  together  with  the  other  companies  of  the  Group  that  are  part  of  the  Claim,  filed  an  appeal  to  the  resolution  dated 
February 15, 2019. 

As described on Note 2.c, according to the preliminary status of the lawsuit, the complexity of the demand and the evidence that have to submit both 
parties,  the  Company  will  continuously  reevaluate  the  evolution  of  the  described  circumstances  as  they  happen  and  its  impact  on the results  and  the 
financial condition of the Group. 

The  Company,  YPF  Holdings,  CLH  Holdings,  Inc.  and  YPF  International  will  file  and  interpose  the  necessary  legal  remedies  and  will  exercise  the 
defensive measures in accordance with the applicable legal procedure in order to defend their rights.

ISSUES RELATED TO MAXUS ENTITIES (Cont.) 

27.a.4) Background of Maxus and TS 

In  connection  with the  sale  of  Diamond  Shamrock Chemicals Company  (“Chemicals”)  to Occidental  Petroleum  Corporation (“Occidental”)  in  1986, 
Maxus  agreed  to  indemnify  Chemicals  and  Occidental  from  and  against  certain  liabilities  relating  to  the  business  or  activities  of  Chemicals  prior  to 
September 4, 1986 (the “selling date”), including environmental liabilities relating to chemical plants and waste disposal sites used by Chemicals prior 
to the selling date. The indemnity obligation and other liabilities described under 27.a.6 determined that Maxus, TS and other related companies submit 
a reorganization petition under the Bankruptcy Law mentioned above. 

27.a.5) Maxus and TS Matters 

The following are the alleged liabilities borne by the Debtors in their reorganization petition, updated up to the date of filing, the date on which YPF 
Holdings ceased to have control over the relevant activities of the Debtors (see point b) of the present Note). 

27.a.5.i) Environmental administrative issues relating to the lower 8 miles of the “Passaic River” 

•

Newark, New Jersey

A  consent  decree,  previously  agreed  upon  by  the  U.S.  Environmental  Protection  Agency  (“EPA”),  the  New  Jersey  Department  of  Environmental 
Protection and Energy (“DEP”) and Occidental, as successor to Chemicals, was entered in 1990 by the United States District Court of New Jersey and 
requires implementation of a remedial action plan at Chemical’s former Newark, New Jersey agricultural chemicals plant. 

•

Passaic River, New Jersey 

Maxus, complying with its contractual obligation to act on behalf of Occidental, negotiated an agreement with the EPA (the “1994 AOC”) under which 
TS has conducted testing and studies near the Newark plant site, adjacent to the Passaic River. 

In 2003, the DEP issued Directive No. 1 seeking to identify those responsible for the damages to natural resources resulting from almost 200 years of 
historic  industrial  and  commercial  development  along  a  portion  of  the  Passaic  River  and  a  part  of  its  basin.  Directive  No. 1  asserts  that  the  notified 
companies,  including  Maxus  and  Occidental,  are  jointly  and  severally  liable  for  the  mentioned  environmental  damage,  despite  all  evidence  to  the 
contrary.  Directive  No.1  demanded  compensation  for  the  restoration,  identification,  and  quantification  of  the  damage  and  determination  of  its  value. 
Despite negotiations between the said entities, no agreement was reached and the DEP assumed jurisdiction in this matter. 

In 2004, the EPA and Occidental entered into an administrative order on consent (the “2004 AOC”) pursuant to which TS (on behalf of Occidental) has 
agreed  to  conduct  testing  and  studies  to  characterize  contaminated  sediment  and  biota  and  evaluate  remedial  alternatives  in  the  Newark  Bay  and  a 
portion of the Hackensack, the Arthur Kill and Kill van Kull rivers. The initial fieldwork on this study was substantially completed. Discussions with the 
EPA  regarding  additional  work  that  might  be  required  are  underway.  The  EPA  issued  General  Notice  Letters  to  other  companies  concerning  the 
contamination of Newark Bay and the works that were performed by TS under the 2004 AOC. 

In December 2005, the DEP issued a directive to TS, Maxus and Occidental directing said parties to pay the State of New Jersey’s cost of developing a 
Source  Control  Dredge  Plan  in  the  lower  six-mile  portion  of  the  Passaic  River.  The  development  of  this  plan  was  estimated  by  the  DEP  to  cost 
approximately US$ 2 million. 

While  some  remedial  works  are  underway,  the  works  under  the  1994  AOC  was  substantially  subsumed  by  reason  of  an  administrative  arrangement 
dated 2007 (the “2007 AOC”) with about 70 companies (including Occidental and TS) in the lower portion of the Passaic River due to an administrative 
agreement of 2007 (“the 2007 AOC”).

ISSUES RELATED TO MAXUS ENTITIES (Cont.) 

Under  the  2007  AOC,  the  lower  17  miles  of  the  Passaic  River,  from  the  mouth  at  Newark  Bay  to  Dundee  Dam,  should  have  been  subjected  to  a 
Remedial Investigation / Feasibility Study (“RI/FS”).The AOC 2007 participants discussed the possibility of carrying out additional remediation work 
with the EPA. The companies that accepted to fund the RI/FS have negotiated an interim allocation of RI/FS costs among themselves based on a number 
of considerations. This group is called the Cooperative Parties Group (the “CPG”). The AOC 2007 was coordinated in a federal, state, local and private 
sector cooperative effort called the Restoration Project for the lower reaches of the Passaic River (“PRRP”). 

EPA’s conclusions regarding the 2007 AOC indicated that the discharges of the underwater sewage pipe are an active source of hazardous substances in 
the lower sections of the Passaic River under study. During the first semester of 2011, Maxus and TS, acting on behalf of Occidental, entered into an 
administrative  agreement  with  the  EPA  (the  “CSO  AOC”),  which  establishes  the  implementation  of  studies  of  the  underwater  sewage  pipe  on  the 
Passaic River, and confirms that there are no pending obligations under the AOC 1994. In the last semester of 2014, TS filed its report with the EPA 
(thus completing phase 1).TS estimated, as of December 31, 2015, that the total cost to implement the CSO AOC is approximately US$ 5 million and 
will take approximately 2 years to be completed once EPA authorizes phase 2 (the work plan). 

On May 29, 2012, Occidental, Maxus and TS withdrew from the CPG under protest and reserving all their rights. However, Occidental continues to be a 
member of the 2007 AOC and its withdrawal from the CPG has not changed its obligations under the 2007 AOC. 

In addition, in August 2007, the National Oceanic Atmospheric Administration (“NOAA”) sent a letter to a number of entities it alleged have a liability 
for natural resources damages, including TS and Occidental, requesting that the group enter into an agreement to conduct a cooperative assessment of 
natural resources damages in the Passaic River and Newark Bay. In November 2008, TS and Occidental entered into an agreement with the NOAA to 
fund a portion of the costs it has incurred and to conduct certain assessment activities during 2009. Approximately 20 other PRRP members have also 
entered into similar agreements. In November 2009, TS declined to extend this agreement.

Feasibility Study for the environmental remediation of the lower 8.3 miles of the Passaic River– Record of Decision (“ROD”) 

On June 2007, the EPA released a draft Focused Feasibility Study (the “FFS 2007”). The FFS 2007 outlines several alternatives for remedial action in 
approximately the lower 8.3 miles of the Passaic River. On April 11, 2014, the EPA published a new FFS draft (“FFS 2014”). The FFS 2014 contains 
four  remediation  alternatives  analyzed  by  the  EPA,  as  well  as  the  estimate  of  the  cost  of  each  alternative,  which  consist  of:  (i) no  action;  (ii) deep 
dredging  with  9.7 million  cubic  yards  of  filling  material;  (iii) filling  and  dredging  of  4.3 million  cubic  yards  and  the  placement  of  a  physical  barrier 
mainly built of sand and stone (tapa de ingeniería); and (iv) focused dredging with 1 million cubic yard of filling material. On March 4, 2016, the EPA 
issued the ROD choosing Alternative 3 as a remedy to remove the contaminated sediments. The estimated cost is US$ 1,382 million (estimated present 
value at a rate of 7%). 

The ROD requires  the removal of 3.5 million cubic  yards of sediment from the  lower  8.3  miles of the Passaic  River by  bank-to-bank  dredging, to a 
depth of approximately 5 to 30 feet in the federal navigation channel from mile 0 to mile 1.7, and approximately 2.5 feet in the remaining areas of the 
lower 8.3 miles of  the Passaic River. A two-foot  thick cap  will be installed  over  the dredged  areas. Contaminated segments  would be  transported to 
disposal  sites  outside  the  state.  The  EPA  estimates  the  whole  project  will  take  approximately  11  years,  including  one  year  for  negotiations  among 
potentially responsible parties, three to four years for project design and six years for its implementation. 

On March 31, 2016, the EPA notified to more than one hundred potentially responsible parties, including Occidental Chemical Corporation (“OCC”), of 
the liabilities relating to the 8.3 mile area of the Passaic River relating to the ROD. In the same notice the EPA stated that it expected OCC (against 
whom Maxus is litigating a dispute over indemnity) to prepare the remediation plan design and that it would send a second letter with an administrative 
proposal to this end, which was received by counsel to OCC, Maxus and TS on April 26, 2016.

ISSUES RELATED TO MAXUS ENTITIES (Cont.) 

As  of  the  date  of  the  Maxus  Entities’  bankruptcy  filing,  OCC  under  Chapter  11,  Maxus  and  TS  were  holding  discussions  with  EPA  to  define  their 
participation in a potential negotiation aimed at taking part in the design of the EPA’s proposed remediation plan, taking into account that the ROD has 
identified over one hundred potentially responsible parties and eight contaminants of concern, many of which have not been generated at the Lister Site. 
As of such date, Maxus was evaluating the situation resulting from the issuance of the ROD by the EPA, as well as its subsequent associated letters.

Removal Action Next to Lister Avenue Site 

During June 2008, the EPA, Occidental, and TS entered into an Administrative Order of Consent, pursuant to which TS, on behalf of Occidental, will 
undertake a removal action of sediment from the Passaic River in the vicinity of the former Diamond Alkali facility. This action results in the removal 
of approximately 200,000 cubic yards of sediment, which will be carried out in two different phases. The first phase, which commenced in July 2011 
and  was  substantially  completed  in  the  fourth  quarter  of  2012.  The  EPA  conducted  a  site  inspection  in  January  2013,  and  TS  received  written 
confirmation of completion in March 2013. 

The term for compliance with the second phase began after the agreement entered into with EPA regarding certain aspects related to the development of 
the  same.  The  Focused  Feasibility  Study  (“FFS”)  published  on  April 11,  2014  provides  that  Phase  II  of  the  removal  action  was  consistently 
implemented with the FFS. On September 18, 2014, the EPA requested that Tierra Solutions, Inc. (“TS”) conducted an additional sampling of the Phase 
II area. The sampling was completed in the first quarter of 2015 and TS is expected to present the validated results to the EPA during 2016. 

27.a.5.ii) Environmental administrative issues relating to the lower 17 miles of the “Passaic River” – feasibility study 

•

Feasibility study for the lower 17 miles of the Passaic River 

Notwithstanding what is discussed above, the lower 17-mile section of the Passaic River, (the area contemplated in AOC 2007), was subject to a RIF/FS 
study expected to be completed by 2015, after which EPA would choose a remediation action that will be made public in order to receive comments. 

The CGP (“Cooperation Group Parties”) submitted in the first semester of 2015, the draft of the RI/FS in which offers potential remediation alternatives, 
(which comprises the lower 8 miles of the Passaic River) of the EPA. The EPA may or may not consider this report. 

27.a.5.iii) Other environmental proceedings 

Other matters relating to the eventual liability of Maxus and TS include liabilities arising from: (a) a ferrous chromate processing plant in Kearny, New 
Jersey; (b) the Standard Chlorine Chemical Company Superfund Site; (c) a ferrous chromate processing plant in Painesville, Ohio; (d) certain removals 
of contaminants located in Greens Bayou; (e) the Milwaukee Solvay Coke & Gas site located in Milwaukee, Wisconsin; (f) the Black Leaf Chemical 
Site, Tuscaloosa Site, Malone Services Site and Central Chemical Company Superfund Site (Hagerstown, Maryland); (g) the remediation action in Mile 
10.9. 

27.a.6) Trial for the Passaic River 

In relation to the alleged contamination related to dioxin and other hazardous substances in the lower stretch of the Passaic River, Newark Bay, other 
nearby  waterways  and  surrounding  areas,  the  DEP  sued  YPF  Holdings,  TS,  Maxus  and  several  companies,  including  Occidental.  The  DEP  sought 
remediation of natural resources damages and punitive damages and other matters. 

The defendants made responsive pleadings and filings.

ISSUES RELATED TO MAXUS ENTITIES (Cont.) 

In March 2008, the Court denied motions to dismiss by Occidental, TS and Maxus. The DEP filed its Second Amended Complaint in April 2008. YPF 
filed  a  motion  to  dismiss  for  lack  of  jurisdiction  of  the  New  Jersey  Court  over  YPF  because  it  was  a  foreign  company  lacking  the  requirements  to 
become a party to a lawsuit in such Courts. The previously mentioned motion filed by YPF was denied in August 2008, and the denial was confirmed by 
the Court of Appeal. 

Without  prejudice  to  the  foregoing,  the  Court  denied  the  plaintiffs’  motion  to  bar  third  party  practice  and  allowed  defendants  to  file  third-party 
complaints. Consequently, third party claims against approximately 300 companies and governmental entities (including certain municipalities) which 
could have responsibility in connection with the claim were filed in February 2009. DEP filed its Third Amended Complaint in August 2010, adding 
Maxus International Energy Company and YPF International as additional named defendants. During the course of the litigation, the third parties filed 
motions to sever and stay and motions to dismiss. The motions were rejected by the judge. Some of the entities appealed the court decision, but such 
appeals were dismissed in March 2011. 

In May 2011, the judge issued Case Management Order No. XVII (CMO XVII), which contained the Trial Plan for the case. This Trial Plan divides the 
case into two phases, each with its own mini-trials (“Tracks” or “procedural stages”) which totaled nine Tracks considered individual trials. Phase one 
would  determine  liability  and  phase  two  would  determine  damages.  Regarding  the  sub-stages:  (a) sub-stages  I  to  III  (Tracks  I  to  III)  correspond  to 
damage  claimed  by  Occidental  and  the  State  of  New  Jersey;  (b) sub-stages  IV  to  VII  (Tracks  IV  to  VII)  correspond  to  liability  for  alter  ego  and 
fraudulent conveyance with respect to YPF, Maxus and Repsol and to the liability of third parties to Maxus; (c) sub-stage VIII (Track VIII) corresponds 
to  damages  claimed  by  the  State  of  New  Jersey;  (d) sub-stage  IX  (Track  IX)  is  the  percentage  of  liability  that  would  correspond  to  Maxus  for  the 
cleanup and remediation costs. 

Specifically,  sub-stage  III  (Track  III)  will  determine  the  extent  of  Maxus’  liability  for  the  operation  of  the  Lister  Site;  sub-stage  IV  (Track  IV)  will 
determine the possible scope of YPF and Repsol’s liability for damages to the Lister Site (alter ego and fraudulent conveyance). 

Following the issuance of CMO XVII, the State of New Jersey and Occidental filed motions for partial summary judgment. The State filed two motions: 
the first one against Occidental and Maxus on liability under the Spill Act, and against TS on liability under the Spill Act. In addition, Occidental filed a 
motion  for  partial  summary  judgment  that  Maxus  owes  a  duty  of  contractual  indemnity  to  Occidental  for  liabilities  under  the  Spill  Act.  In  July  and 
August 2011, the judge ruled that, although the discharge of hazardous substances by Chemicals was proven, liability allegation could not be made if the 
nexus between any discharge and the alleged damage is not established. Additionally, the Court ruled that TS has Spill Act liability to the State based on 
(1) its current ownership of the site where the discharges were made (Lister Avenue); and (2) that Maxus has the obligation to indemnify Occidental 
(previously mentioned). 

In November 2011, the Special Master called for and held a settlement conference between the State of New Jersey, on the one hand, and Repsol S.A., 
YPF and Maxus, on the other hand to discuss the parties’ respective positions, but no agreement was reached. 

In  February  2012,  the  plaintiffs  and  Occidental  filed  motions  for  partial  summary  judgment,  seeking  summary  adjudication  that  Maxus  has  liability 
under  the  Spill  Act  of  New  Jersey.  The  Judge  held  that  Maxus  and  TS  have  direct  liability  for  the  contamination  generated  into  the  Passaic  River. 
Volume, toxicity and cost of the contamination have not been verified yet. 

On  September 11,  2012,  the  Court  issued  the  Track  VIII  order.  The  Track  VIII  order  governs  the  process  by  which  the  Court  would  conduct  the 
discovery  and  trial  of  the  claim  for  damages  of  the  State  of  New  Jersey  (the  “Administration”)  against  Occidental,  Maxus  and  TS  (caused  by  the 
Diamond Alkali Lister Avenue plant).

ISSUES RELATED TO MAXUS ENTITIES (Cont.) 

On  September 27,  2012,  Occidental  filed  its  Amended  Cross-Claims  and  the  following  day,  the  State  of  New  Jersey  (the  “Administration”)  filed  its 
fourth Amended Complaint. The principal changes to the Administration’s pleading concern the State’s allegations against YPF and Repsol, which were 
included  in  its  cross-claim.  In  particular,  based  on  the  Mosconi  Report  of  the  Argentine  State,  three  new  allegations  against  Repsol  were  included 
involving asset stripping from Maxus and YPF. 

During the fourth quarter of 2012 and the first quarter of 2013, YPF, YPF Holdings, Maxus and TS together with certain other direct defendants in the 
litigation, have engaged in on-going mediation and negotiation seeking to settle Track VIII with the State of New Jersey. During this time, the Court has 
stayed the litigation. On March 26, 2013, the State advised the Court that a proposed settlement between the State and certain third party defendants had 
been  approved  by  the  requisite  threshold  number  of  private  and  public  third  party  defendants.  The  respective  Boards  of  Directors  of  YPF,  YPF 
Holdings, Maxus and TS approved at their Board meetings the settlement agreement (the “Agreement”). The proposal of the Agreement, which did not 
imply endorsement of facts or rights and presented only for conciliatory purposes, was subject to an approval process, publication, comment period and 
court  approval.  According  to  the  terms  of  the  Agreement,  the  state  of  New  Jersey  would  agree  to  release  certain  claims  related  with  environmental 
liabilities  within  a  geographic  area  of  the  Passaic  River,  New  Jersey  initiated  against  YPF  and  certain  subsidiaries,  recognizing  to  YPF  and  other 
participants in the litigation, a limited liability of up to US$ 400 million, if they are found responsible. In return, Maxus would make cash payment of 
US$ 65 million at the time of approval of the Agreement. 

In  September  2013,  the  Court  published  its  Case  Management  Order  XVIII  (“CMO  No.  XVIII”),  which  provides  a  schedule  for  approval  of  the 
Agreement. Pursuant to the CMO XVIII, the Court rejected Occidental’s claims and approved the Agreement. Occidental appealed the approval of the 
Agreement, which was dismissed. Notwithstanding the foregoing, on February 10, 2014, in compliance with the settlement agreement, Maxus made a 
deposit of US$ 65 million in an escrow account. On April 11, 2014, Occidental notified the parties that it would not seek an additional revision of the 
approval of the Agreement. 

On August 20, 2014, the lawyers of the State of New Jersey reported that Occidental and the State of New Jersey had entered into an agreement on the 
general  terms  and  conditions  of  a  settlement  agreement  that  would  end  the  Track  VIII  proceedings.  On  December 16,  2014,  the  Court  approved  the 
Settlement Agreement whereby the State of New Jersey agreed to settle all claims against Occidental related to the environmental liabilities within a 
specific geographical area of the Passaic River, New Jersey, in consideration for the payment of US$ 190 million in three installments, the last payable 
on June 15, 2015; and a sum amounting up to US$ 400 million if the State of New Jersey had to pay its percentage for future remedial actions. 

On  January 5,  2015,  Maxus  received  a  letter  from  Occidental  requesting  Maxus,  pursuant  to  the  purported  contractual  obligation  to  indemnify 
Occidental, to compensate Occidental for all the payments that Occidental agreed to pay to the Administration. Maxus holds that both the existence and 
the amount of such obligation to indemnify under the settlement agreement are pending issues that must wait for the Court decision on the Passaic River 
case. 

In addition, on July 31, 2014 Occidental submitted its third amendment to the complaint YPF, Repsol and Maxus filed motions to limit Occidental’s 
third amended complaint arguing that such claims were not included in the second. Occidental answered that the third amendment incorporated new 
facts, but not new claims. The Court rejected Occidental’s arguments and dismissed the third amendment to the complaint. 

Moreover, Repsol countersued Occidental alleging that the US$ 65 million paid by Repsol as per the agreement between Repsol, YPF, YPF Holdings, 
Maxus and Tierra Solutions with the State of New Jersey was paid for damages caused by (a) Chemicals, for which Occidental is liable under the share 
purchase agreement of 1986 or (b) Occidental’s individual conduct. 

On April 15, 2015, Occidental sent Maxus a letter claiming indemnity protection under the share purchase agreement with respect to the counterclaim 
filed by Repsol against Occidental. On 28 April 2015, Maxus replied contesting the claims reserving all arguments and defenses regarding the SPA’s 
indemnification provisions.

ISSUES RELATED TO MAXUS ENTITIES (Cont.) 

Furthermore, the scheduled dates were changed through Case Management Order XXVI Depositions of witnesses residing in the U.S. and abroad began 
in  December  2014.  Nearly  forty  witnesses  deposed  in  the  case,  including  the  corporate  representatives  of  all  the  parties.  The  issues  being  explored 
include  Track  IV  (the  alter  ego  and  fraudulent  transfers  of  assets)  and  Track  III  (indemnity  claims  filed  by  OCC  against  Maxus).  Depositions  of 
witnesses were completed in mid-October 2015. 

Notwithstanding the above, the Special Master authorized the parties to file briefs specifying any issue in respect of which each party believed that the 
court should authorize early summary judgment motions. The motions filed by the parties and the non-binding opinions as issued by the Special Master 
on January 14, 2016, are summarized below: 

(a) YPF filed for early summary judgment against OCC on four issues: i) dismissal of the portion of OCC’s claims for alter ego liability, based on the 

financing of YPF’s acquisition of Maxus shares in 1995; ii) dismissal of the portion of OCC’s claims for alter ego liability, based on the transfer 
of Maxus’ assets from 1995 through 1999; iii) dismissal of the portion of OCC’s liability claims based on the alleged “control” by YPF of 
Maxus’s Board of Directors’ decision, in 1996, to sell its subsidiaries in Bolivia and Venezuela to YPF International; and iv) dismissal of the 
portion of OCC’s claims for alter ego liability, based on the transfer of Maxus’ environmental liabilities to Tierra in 1996. 

The  Special  Master’s  Recommendation  on  YPF’s  motion  recommended  to  deny  the  motion  on  the  grounds  that  i)  the  statute  of  repose  for 
fraudulent transfers is not applicable to the remedy of alter ego for breach of contract and ii) a finder of fact should be permitted to consider all 
portions of YPF actions when determining if there is alter ego liability so dismissal of portions of these claims is inappropriate. 

(b) OCC filed a motion for early summary judgment against Maxus in relation to Occidental’s claim to recover the amount of US$ 190 million (plus 

expenses) under the settlement agreement. 

The motion sought to establish that Maxus is liable for all obligations at the Lister Site, regardless of any actions taken by OCC (including the 
period  of  time  that  the  OCC  operated  Lister  Site).  Therefore,  the  Special  Master’s  Recommendation  on  OCC’s  motion  against  Maxus 
recommended to grant the motion on the grounds that (i) the language of the SPA was not ambiguous and required Maxus to indemnify OCC for 
its  own  conduct  at  the  Lister  Site  and  (ii) OCC  was  not  estopped  from  seeking  indemnity  from  Maxus  for  its  own  conduct  at  the  Lister  Site 
because  it  did  not  take  inconsistent  legal  positions  in  prior  litigations.  Notwithstanding  the  foregoing,  Occidental  will  have  to  prove  the 
reasonableness of the US$ 190 million amount settled with the State of New Jersey, for which Maxus may eventually be liable. 

In addition, OCC filed for early summary judgment dismissing the cross-claims of Repsol against OCC, which seek to recover from OCC the US$ 
65 million payment made by Repsol to New Jersey State under the settlement agreement. 

The  Special  Master’s  Recommendation  on  OCC’s motion  against  Repsol  recommended  to deny  the  motion  in  part  as  to  Repsol’s  contribution 
claim and to grant the motion in part as to Repsol’s unjust enrichment claim, on the grounds that i) Repsol’s contribution claims are permissible 
under the New Jersey Spill Act even if a settlement did not fully discharge liability to the State; ii) demonstrating Repsol’s liability under the Spill 
Act  is  not  a  prerequisite  for  Repsol  to  receive  contribution  from  OCC;  iii)  Repsol  is  not  liable  to  OCC  for  indemnification  as  an  alter  ego  of 
Maxus, and iv) OCC was not unjustly enriched when Repsol settled with the state. 

(c)

Repsol filed for early summary judgment against OCC to dismiss OCC’s cross-claims: i) to the extent that OCC’s claims are based on prescribed 
claims for fraudulent transfers; ii) on the grounds that OCC cannot prove that it has suffered damages due to a failure to perform an agreement; iii) 
on the grounds that OCC cannot prove that Repsol has caused any damage even if a non-performance occurred, because OCC has alleged that 
Maxus became insolvent before Repsol acquired YPF in 1999; and iv) on the grounds that OCC has failed to pierce the corporate veil between 
YPF and Repsol. 

The Special Master’s Recommendation on Repsol’s motion against OCC recommended granting the motion because the OCC failed to set out any 
basis to pierce the corporate veil between YPF and Repsol, which the Special Master held OCC was required to do, and because OCC did not 
allege that YPF was insolvent.

ISSUES RELATED TO MAXUS ENTITIES (Cont.) 

(d) Maxus filed for early summary judgment against OCC to dismiss the claims for damages filed by OCC regarding costs not yet incurred by OCC 

(future remediation costs). YPF joined in this motion. 

The  Special  Master’s  Recommendation  on  Maxus’s  motion  against  OCC  was  to  grant  the  motion  on  the  grounds  that  OCC’s  request  for 
declaratory judgment has no basis due to the uncertainty regarding future costs. 

(e)

Finally, related to the claims that OCC sought to add against YPF and Repsol for alleged interference with OCC’s contractual rights under the 
Stock Purchase Agreement of 1986 (between Maxus and OCC), the Special Master recommended that the motion be denied on the grounds that 
OCC improperly delayed in seeking to supplement its claims despite having multiple earlier opportunities to do so. 

The parties appealed the respective Special Master’s Recommendations on February 16, 2016. On February 18, 2016, the parties sought leave from the 
Special  Master  to  file  additional  motions  for  summary  judgment.  On  March 7,  2016,  the  Special  Master  denied  each  of  the  parties’  requests  to  file 
additional motions, while ruling that the parties could raise the factual issues raised in the motions at the time of trial as motions in limine. On April 5, 
2016, the judge denied the motions and adopted the Special Master’s Recommendations in their entirety. 

On April 25, 2016, the parties moved to request permission to file interlocutory appeals and a stay of the litigation during the appellate proceedings. 
Maxus filed a motion requesting permission to appeal the ruling granting summary judgment to OCC against Maxus, which held that Maxus is liable 
under the stock purchase and sale agreement for all obligations under, or arising from, the Lister Site, even if attributable to OCC’s own acts. YPF filed 
a motion requesting permission to appeal the ruling denying its motion for summary judgment and Occidental filed a motion, appealing the ruling that 
granted Repsol its motion for summary judgment, On May 24, 2016, the Superior Court of New Jersey—Appellate Division denied all interlocutory 
appeals. 

On April 5, 2016, the Superior Court issued Case Management Order XXVIII establishing the trial date as June 20, 2016. However, all litigation against 
Maxus and YPF has been stayed upon Maxus’ filing under Chapter 11 of the Bankruptcy Code. 

On  June 20,  2016,  Occidental  filed  a  Notice  of  Removal  of  Claims  and  a  motion  to  transfer  venue  of  the  remaining  claims  in  the  Passaic  River 
Litigation  from  the  New  Jersey  Bankruptcy  Court  to  the  Delaware  Bankruptcy  Court.  On  June 28,  2016,  the  New  Jersey  Bankruptcy  Court  granted 
Occidental’s motion to transfer venue. 

On  July 20,  2016,  Repsol  filed  a  motion  with  the  Delaware  Bankruptcy  Court  to  have  its  cross-claims  seeking  environmental  contribution  from 
Occidental  under  the  Spill  Act  to  be  remanded  to  the  New  Jersey  Superior  Court.  On  November 15,  2016,  the  Bankruptcy  Court  granted  Repsol’s 
motion  to  remand.  On  November 29,  2016,  Occidental  filed  a  motion  for  clarification  or,  in  the  alternative,  for  reconsideration  of  the  Bankruptcy 
Court’s Order granting Repsol’s motion to remand. At a hearing on January 25, 2017, the Delaware Bankruptcy Court denied Occidental’s motion and 
allowed Repsol’s cross-claims to go forward in the New Jersey Superior Court. 

27.b) Accounting matters 

In connection with the petition that the Maxus Entities filed with the Bankruptcy Court on June 17, 2016, as described in detail in part a) of this Note, 
the  Management  of  the  Company  considered  this  an  event  that  required  reconsideration  of  whether  the  consolidation  of  such  entities  remained 
appropriate.  In  order  to  carry  out  this  analysis,  the Company  followed  the  guidelines  established in  IFRS  10 “Consolidated Financial Statements”  to 
reassess  whether  it  maintained  control  over  the  activities  of  the  Maxus  Entities.  This  analysis,  in  accordance  with  IAS  8,  was  complemented  by  the 
criteria set forth in the United States Standard ASC 810 published by the FASB, the principles of which are consistent with IFRS 10, but addresses in 
more detail the issues related to the consolidation of entities that file a reorganization proceeding under Chapter 11.

ISSUES RELATED TO MAXUS ENTITIES (Cont.) 

Generally, when an entity files a petition under Chapter 11, shareholders do not generally maintain the ability to exercise the power to make decisions 
that have a significant impact on the economic performance of the business of entities because that power is subject to Bankruptcy Court approval. 

The petition filed by the Maxus Entities under Chapter 11 had relevant effects on the rights of YPF Holdings as a shareholder of these entities, because 
creditors replaced the shareholders in their legal capacity to file derivative suits against the directors on behalf of the entities for breach of the Debtors’ 
fiduciary obligations, since the creditors would be the main beneficiaries in any increase in value of these entities. However, at the time of the filing 
under Chapter 11, it should be noted that YPF Holdings retained its right to designate directors of the Debtors through Shareholders’ Meetings, unless 
the Bankruptcy Court orders otherwise. In addition, the bankruptcy cases also affected the responsibilities and functions of the board of directors and 
management of each of the respective Maxus Entities. Each of the Maxus Entities had become a “Debtor in Possession” and, in accordance with the 
Bankruptcy Code, remained in possession of its property and, subject to certain limitations, was authorized to carry out its normal operations, unless the 
Bankruptcy Court ordered otherwise. Nevertheless, during the Chapter 11 cases, the directors of the Debtors do not have absolute discretion, since any 
transaction “outside the ordinary course of business” of the Debtors, such as the sale of a significant asset, the expansion of a line of business involving 
the use of significant funds (or the commitment to do so), or the provision of loans or other types of financing, will be subject to the approval of the 
Bankruptcy Court. 

Likewise, on November 8, 2016, the Maxus Entities amended their by-laws in order to give greater discretion to the independent directors. 

As a result, due to the Chapter 11 filing, YPF Holdings is not empowered to make decisions unilaterally, which could significantly affect the Debtors’ 
businesses,  both  operationally  and  economically.  Likewise,  the  Debtors  are  required  to  seek  the  approval  of  the  Bankruptcy  Court  for  typical 
commercial activities, if such activities could have a significant effect on their operations or on any of their stakeholders. 

In view of the foregoing, the Management of the Company understands that, it is no longer able to exercise its power over such entities to significantly 
influence on the Maxus Entities’ operations and results, a necessary condition established by IFRS 10 to establish the existence of an effective financial 
control and therefore, it proceeded to deconsolidate the investments in the Maxus Entities from June 17, 2016. 

According to ASC 810, this loss of control may involve a gain or loss for the controlling company, since the controlling company must reconcile its 
non-controlling interest at fair value after deconsolidating the assets and liabilities of the entities. The obligations related to the reorganization process 
undertaken as described in part a) of this Note have also been considered for purposes of this calculation. As a result, in fiscal year 2016, the Group has 
recorded a gain of 1,528 in “Other net operating results”. 

28. CONTINGENT ASSETS AND LIABILITIES 

28.a) Contingent assets 

The Group does not have any significant contingent assets. 

28.b) Contingent liabilities 

The Group has the following contingencies and claims, individually significant, that the Management of the Company, in consultation with its external 
counsels, believes have possible outcome. Based on the information available to the Group, including the amount of time remaining before trial among 
others, the results of discovery and the judgment of internal and external counsel, the Group is unable to estimate the reasonably possible loss or range 
of loss on certain matters referred to below:

28.b.1) Environmental claims 

•

Asociación Superficiarios de la Patagonia (“ASSUPA”) 

In  August  2003,  ASSUPA  sued  18  companies  operating  exploitation  concessions  and  exploration  permits  in  the  Neuquén  Basin,  YPF  being  one  of 
them,  claiming  the  remediation  of  the  general  environmental  damage  purportedly  caused  in  the  execution  of  such  activities,  in  addition  to  the 
establishment of an environmental restoration fund, and the implementation of measures to prevent environmental damages in the future. The plaintiff 
requested that the Argentine Government, the Federal Environmental Council (Consejo Federal de Medio Ambiente), the Provinces of Buenos Aires, La 
Pampa,  Neuquén,  Río  Negro  and  Mendoza  and  the  Ombudsman  of  the  Nation  be  summoned.  It  requested,  as  a  preliminary  injunction,  that  the 
defendants  refrain  from  carrying  out  activities  affecting  the  environment.  Both  the  Ombudsman’s  summons  as  well  as  the  requested  preliminary 
injunction  were  rejected  by  the  CSJN.  YPF  has  answered  the  demand  requesting  its  rejection,  opposing  failure  of  the  plaintiff  and  requiring  the 
summons  of  the  Argentine  Government,  due  to  its  obligation  to  indemnify  YPF  for  events  and  claims  before  January 1,  1991,  according  to  Law 
No. 24,145  and  Decree  No. 546/1993.  The  CSJN  gave  the  plaintiffs  a  term  to  correct  the  defects  in  the  complaint.  On  August 26,  2008,  the  CSJN 
decided  that  such  defects  had  already  been  corrected  and  on  February 23,  2009,  ordered  that  certain  provinces,  the  Argentine  Government  and  the 
Federal Environmental Council be summoned. Therefore, pending issues were deferred until all third parties impleaded appear before the court. As of 
the  date  of  issuance  of  these  consolidated  financial  statements,  the  provinces  of  Río  Negro,  Buenos  Aires,  Neuquén,  Mendoza,  and  the  Argentine 
government have made their presentations, which are not available to the Company yet. The Provinces of Neuquén and La Pampa have claimed lack of 
jurisdiction, which was answered by the plaintiff. 

On December 30, 2014, the CSJN issued two interlocutory judgments. By the first, it supported the claim of the Provinces of Neuquén and La Pampa, 
and declared that all environmental damages related to local and provincial situations were outside the scope of his original competence, and that only 
“inter-jurisdictional situations” (such as the Colorado River basin) would fall under his venue. 

By the second judgment, the Court rejected the petition filed by ASSUPA to incorporate Repsol and the directors who served in YPF until April 2012 as 
a necessary third party. The Court also rejected precautionary measures and other proceedings related to such request. 

In addition, it should be highlighted that YPF learned about other three court complaints filed by ASSUPA against: 

(i)

Concessionary companies in the San Jorge Gulf basin areas 

On December 28, 2016, YPF received notice of the complaint. The deadline set for preliminary defenses was May 31, 2017, and the deadline to 
respond to the complaint was June 30, 2017. YPF has timely filed a defense for a legal flaw and the court ordered the suspension of the terms to 
answer the complaint. The terms will continue to be suspended until a final decision is entered thereon asserted by the company. 

(ii) Concessionary companies in the Austral basin areas 

A highly summarized action has been ordered. In addition, an interim relief has been issued by the Lower Court to notify several companies of the 
existence  of  the  suit,  and  for  the  defendants  to  contribute  certain  information.  YPF  appealed  this  decision,  and  the  Court  of  Appeals  partially 
upheld the appeal, reversing the lower court ruling ordering various entities to provide notification of this claim. In the same decision, the Court of 
Appeals confirmed that the defendants had an obligation to provide certain information but stated that YPF and the other defendants had already 
complied  with  such  obligation.  On  November 2,  2015,  YPF  was  notified  of  the  lawsuit.  Following  YPF’s  request,  the  court  ordered  on 
November 4, 2015 to suspend the procedural time limits. 

On November 23, 2017, the plaintiff requested the Court to decide on its motion requesting the National Government and the Provinces of Santa 
Cruz and Tierra del Fuego to be summoned to appear as third parties in compliance with the ruling dated December 6, 2017 whereby the court 
ordered the  issuance of such summons, so  that the  National Government–and the provinces mentioned above  –enter  an appearance in the case 
within the term of 60 days. The court ordered the suspension of deadlines until their appearance or expiration of the deadline.

28. CONTINGENT ASSETS AND LIABILITIES (Cont.) 

On June 4, 2018, the  Argentine  Government  answered as the third party summons sought by the plaintiff, and requested dismissal thereof. On 
August 14, 2018 the province of Tierra del Fuego answered a summons as a third party stating its intention not to voluntarily appear in the case 
and requested its exclusion thereof. On September 11, 2018, the Province of Santa Cruz answered the summons as a third party, stating that it has 
no interest in participating in the case and adhered to what was stated by the Province of Tierra del Fuego. 

(iii) Concessionary companies in the Northwest basin areas 

The  action  was  submitted  to  ordinary  proceedings.  On  December 1,  2014,  the  Company  was  notified  about  the  complaint.  The  procedural 
deadlines  were  suspended  at  the  Company’s  request.  Subsequently,  on  May 3,  2016,  YPF  was  once  again  notified  of  the  complaint,  and  the 
deadlines  were  reinstated.  Consequently,  the  Company  filed  a  motion  requesting  that  the  deadlines  be  suspended  until  the  plaintiff  clarifies 
whether or not it will annex certain documentary evidence referred to in the complaint. The Judge sustained the Company’s motion and suspended 
again the deadlines to answer the complaint. On April 19, 2017, YPF was served with notice of the ruling of the Court ordering to resume the 
procedural  time  limits  against  which  YPF  has  timely  filed  a  defense  for  a  legal  flaw.  The  court  has  not  decided  upon  it  yet  and  ordered  the 
suspension of the terms to answer the complaint. The terms will continue to be suspended until a final decision is entered on such defense asserted 
by YPF.

Dock Sud, Río Matanza, Riachuelo, Quilmes and Refinería Luján de Cuyo 

A group of neighbors of Dock Sud, Province of Buenos Aires, have sued 44 companies, among which YPF is included, the Argentine Government, the 
Province of Buenos Aires, the City of Buenos Aires and  14 municipalities, before the CSJN, seeking the remediation and the indemnification of the 
environmental collective damage produced in the basin of the Matanza and Riachuelo rivers. Additionally, another group of neighbors of the Dock Sud 
area,  have  filed  two  other  environmental  lawsuits,  one  of  them  desisted  in  relation  to  YPF,  claiming  several  companies  located  in  that  area,  among 
which  YPF  is  included,  the  Province  of  Buenos  Aires  and  several  municipalities,  for  the  remediation  and  the  indemnification  of  the  environmental 
collective damage of the Dock Sud area and for the individual damage they claim to have suffered. Currently, it is not possible to reasonably estimate 
the outcome of these claims, as long as, if applicable, the corresponding legal fees and expenses that might result. YPF has the right of indemnity by the 
Argentine Government for events and claims prior to January 1, 1991, according to Law No. 24,145 and Decree No. 546/1993. 

By means of judgment dated July 8, 2008, the CSJN: 

(i)

Determined that the Basin Matanza Riachuelo Authority (“ACUMAR”) (Law No. 26,168) should be in charge of the execution of the program of 
environmental remediation of the basin, being the Argentine Government, the Province of Buenos Aires and the City of Buenos Aires responsible 
of its development; delegated in the Federal Lower Court of Quilmes the knowledge of all the matters concerning the execution of the remediation 
and reparation; declared that all the litigations related to the execution of the remediation plan will accumulate and will proceed before this court 
and established that this process produces that other collective actions that have for object the environmental remediation of the basin be 
dismissed (“littispendentia”). YPF has been notified of certain resolutions issued by ACUMAR, by virtue of which YPF has been requested to 
present an Industrial Reconversion Program, in connection with certain installations of YPF. The Program has been presented although the 
Resolutions had been appealed by the Company; 

(ii) Decided that the proceedings related to the determination of the responsibilities derived from past behaviors for the reparation of the 

environmental damage will continue before that Court. 

In  addition  to  the  claims  discussed  under  14.a.4),  which  discusses  environmental  claims  in  Quilmes,  the  Company  has  other  legal  and  non-judicial 
claims against it, based on similar arguments. 

On the other hand, the monitoring tasks carried out routinely by YPF have allowed YPF to warn against degrees of affectation in the subsoil within the 
vicinity of the Luján de Cuyo refinery, which led to the creation of a program for surveying, evaluating and remedying liabilities that the Company is in 
the process of implementing with agencies in the Province of Mendoza, the costs which have been charged to provision in the remediation program of 
environmental issues of the Group.

28.b.2) Contentious claims 

•

Petersen Energía Inversora, S.A.U and Petersen Energía, S.A.U. (collectively, “Petersen”) 

On April 8, 2015, Petersen, former YPF Class D shareholder, filed a lawsuit against the Republic of Argentina and YPF in the Federal District Court for 
the  Southern  District  of  New  York.  The  litigation  is  being  conducted  by  the  bankruptcy  trustee  of  the  previously  mentioned  companies  due  to  a 
liquidation process pending in a Commercial Court in Spain. The complaint contains claims related to the expropriation of the controlling interest of 
Repsol in YPF by the Argentine Republic in 2012, asserting that the obligation by the Argentine Republic to make a purchase offer to the remaining 
shareholders would have been triggered. Claims are grounded on allegations that the expropriation breached contract obligations contained in the initial 
public offering and bylaws of YPF and seeks unspecified compensation. YPF considers that the claim against the Company has no merit and filed a 
motion to dismiss on September 8, 2015, the date which was set as a result of the extension of the term provided for by the Court. On the other hand, 
Petersen filed an objection against YPF’s motion to dismiss. 

On July 20, 2016, the Court held a hearing during which the parties made their arguments regarding the motion to dismiss, and responded to questions 
asked by the Judge. On September 9, 2016, the United States District Court for the Southern District of New York issued a decision partially dismissing 
the  complaint  filed  by  Petersen  against  YPF  at  this  preliminary  stage.  The  Company  appealed  this  decision,  requesting  a  complete  dismissal  of  the 
complaint at this preliminary stage. 

On June 15, 2017, a hearing was held so that the parties could orally present their arguments. 

On July 10, 2018, the United States Court of Appeals for the Second Circuit held that the United States District Court for the Southern District of New 
York  has  jurisdiction  over  this  judicial  matter,  but  without  rendering  an  opinion  as  to  the  merits  of  the  complaint.  The  Company  and  the  Argentine 
Republic appealed such resolution on July 24, 2018 requesting reconsideration by the Court of Appeals that ruled (“Panel rehearing”) or a review of the 
resolution by the Court of Appeals as a whole (“Rehearing en banc”). 

On August 30, 2018, the Rehearing en banc filed by the Company and the Argentine Republic was rejected. For that reason, the process was suspended 
until the case was remanded to the United States District Court for the Southern District of New York. However, YPF requested a stay motion (“stay of 
mandate”),  which  was  granted  on  October 2,  2018  for  a  period  of  thirty  days.  On  October 31,  2018,  the  Company  filed  a  writ  of  certiorari  with  the 
Supreme Court of Justice of the United States so that the process is stayed until this court finally decides on its merits. 

Additionally, the republics of Mexico and Chile appeared in Court as Amicus Curiae. 

On January 7, 2019, the Supreme Court of Justice of the United States requested the Solicitor General (advisor to the U.S. Ministry of Justice in charge 
of all the proceedings pending in the U.S. Supreme Court of Justice) to decide on the admissibility of the writ of certiorari filed by the Company and the 
Argentine Republic. At present, the file is waiting for the Solicitor General to request the opinion of the U.S. Department of State. 

As  of  the  date  of  issuance  of  these  consolidated  financial  statements,  there  are  no  elements  in  YPF’s  possession  that  allow  quantifying  the  possible 
impact that this claim could have on the Company. 

The Company categorically rejects the claims asserted in the complaint for being inadmissible and will file all necessary legal remedies and take all 
defensive measures in accordance with the applicable legal procedure in order to defend its rights.

Eton Park Capital Management, L.P., Eton Park Master Fund, LTD. y Eton Park Fund, L.P. (jointly referred to as “Eton Park”) 

On June 2, 2017, Eton Park, a former YPF shareholder, filed a complaint against the Argentine Republic and YPF in the United States District Court for 
the Southern District of New York, for alleged damages that it would have suffered during the process of expropriation of shares that the Argentine 
Republic  took  over  the  majority  stake  of  Repsol  in  YPF  in  2012.  The  complaint,  which  seeks  unspecified  compensation,  states  that  the  alleged 
obligations assumed in the bylaws and in the initial public offering of YPF shares were violated, which imposed obligations related to a public offering 
made to the rest of the shareholders. 

The claim was temporarily on hold, pending the resolution of the Second Circuit of the United States on the Petersen case; however, after the resolution 
referred to in the preceding paragraph, Eton Park requested that procedural terms be resumed. Likewise, YPF requested the Court to summon the parties 
to a hearing in order to agree on how the trial should proceed, proposing the answer to the complaint be filed within 45 days from the final resolution in 
the Petersen case. 

On  July 30,  2018,  the  Court  ruled  that  the  suspension  of  the  process  will  stand  for  10  days  after  the  date  of  the  Appeal  Court’s  resolution  on  the 
admissibility of the appeal in the Petersen Case, which was filed on July 24, 2018. 

On August 30, 2018, the appeal filed by the Company and the Argentine Republic in the Petersen case was rejected. On October 2, 2018, the stay of 
mandate was granted for thirty days requested by YPF and on October 31, 2018, the Company filed the writ of certiorari, as mentioned in the Petersen 
Case. 

On September 6, 2018, the Company made a filing so that the Eton Park process remained stayed until the stay of mandate in Petersen was still in force. 
On September 11, 2018, the Court granted the petition to the Company. Thus, as the Second Circuit of the United States has not made the “issuance of 
the mandate” in the Petersen case, the Eton Park case remains stayed. 

As  of  the  date  of  these  financial  statements,  there  are  no  factors  that  YPF  can  use  to  quantify  the  possible  impact  that  this  claim  might  have  on  the 
Company. 

The Company categorically rejects the claims asserted in the complaint for being inadmissible and will file all necessary legal remedies and take all 
defensive measures in accordance with the applicable legal procedure in order to defend its rights. 

28.b.3) Claims before the CNDC 

•

Claims for fuel sale prices 

The Group was subject to certain claims before the Antitrust Board, which are related to alleged price discrimination in sale of fuels. And which were 
timely answered by YPF. 

28.b.4) Tax claims 

•

Dispute over the cost deduction for well abandonment 

The  Company  has  consistently  recorded  the  cost  of  abandoning  wells  in  accordance  with  the  criteria  detailed in  Note  2.b.6  and,  in  the  absence  of  a 
specific treatment of that subject in the income tax law and its Regulatory Decree, has deducted the charge for well plugging costs in the calculation of 
this tax, based on the general criteria of the standard for deduction of expenses (accrual criteria). Nevertheless, this interpretation has been objected to by 
the AFIP, which would allow for deductions once the expense has been done. 

Although both consider it a deductible expense, the disagreement between YPF and the AFIP stems from the criteria that each of them uses to decide 
when the obligation to plug arises which, in turn, is the one that determines when the deduction from the income tax should be taken. 

The AFIP understands that the deduction of costs due to the abandonment of wells should be deferred until the taxpayer has the opportunity to proceed 
with plugging the well, once the wells have been exhausted, considering the abandonment of the well to be the event generating the charge for well 
plugging costs.

28. CONTINGENT ASSETS AND LIABILITIES (Cont.) 

On the other hand, the Company, as well as other companies in the oil industry, understands that the event that generates the well plugging costs in 
connection with the abandonment  of wells is  the  act of  drilling, as  the  drilling  constitutes  environmental  impact and,  consequently, the obligation  to 
repair such impact through well plugging arises from that moment. This obligation is not subject to any condition since there is no uncertainty as to 
whether well depletion will inevitably occur. The Company has learned that similar disputes have been raised by the AFIP with other companies in the 
oil industry. 

In  June  2016,  the  Ministry  of  Hydrocarbons  Resources  of  MINEM  (Secretaría  de  Recursos  Hidrocarburíferos  del  MINEM),  the  competent  body  to 
clarify the origin of the legal obligation in the matter, and in response to a consultation of the Chamber of Oil Exploration and Production, ruled in favor 
of the position of the oil companies and concluded that the substantial event generating the charge for the abandonment of wells is the drilling. 

This response of the Chamber has been reported to the AFIP by both the Ministry of Hydrocarbon Resources and by YPF but, with respect to different 
questions  the  AFIP  disregarded  this  position  and,  on  December 29,  2016,  notified  the  Company  of  two  resolutions,  adjusting  the  income  tax  for  the 
fiscal periods 2005 to 2009 and questioning the criteria followed by the Company. On February 20, 2017, YPF filed the corresponding appeal to the 
Fiscal Tribunal of the Nation (Tribunal Fiscal de la Nación) for such unilateral determinations. 

The disputed amount for the years claimed by AFIP amounts to a total of 4,354 considering principal and interest. 

On  June 15,  2018,  the  Company  was  notified  of  the  AFIP’s  determination,  whereby  the  income  tax  for  fiscal  year  2010  was  adjusted  by  1,175.  On 
July 10, 2018 the Company filed the corresponding appeal to the Fiscal Tribunal of the Nation. 

On July 24, 2018, the Company was given notice of the commencement of an inspection procedure regarding fiscal year 2017. 

On November 7, 2018, the Company was notified of the commencement of a determination procedure with respect to the projected adjustment for fiscal 
years 2011 to 2016, inclusive. The Company filed its defense on December 21, 2018. 

Notwithstanding the progress of these proceedings and ongoing investigations (and prosecution of other companies in the industry), the Company, based 
on its opinion and that of its external advisors, considers that it has strong arguments defending the adopted criteria to be strong. Without prejudice to 
the foregoing, the Company will evaluate the most convenient alternatives related to this issue. See Note 30.j.

Dispute over customs duties 

Between  2006  and  2009,  the  Customs  General  Administrations  in  Neuquén,  Comodoro  Rivadavia  and  Puerto  Deseado  brought  certain  summary 
proceedings  based  on  alleged  formal  misstatements  on  future  commitments  of  crude  oil  deliveries  in  the  loading  permits,  for  periods  prior  to  and 
subsequent to the existence of export duties, for which they calculated the difference between the contractual price declared and the price in force at the 
time of export to determine fines under the terms of the Customs Code. 

The  Customs  General  Administration  may  question  whether  the  contractual  price  agreed  to  by  the  Company  and  declared  in  loading  permits  is  an 
appropriate amount when calculating export duties. However, the Company understands that there is no violation for declaring the contractual price of a 
transaction. 

The summaries ended the administrative reviews before the Customs General Administration and are in full appeal before the Argentine Tax Court. On 
March 3, 2017, the Company was notified of an adverse judgment handed down by the Argentine Tax Court regarding the criteria employed for crude 
oil delivery operations after 1998 and for which fines were determined in accordance with Article 954 (c) of the Customs Code for approximately 11 
exports that occurred prior to the existence of export duties. The Company appealed before the Court of Appeals with staying effects.

28. CONTINGENT ASSETS AND LIABILITIES (Cont.) 

On  March 31,  2017,  the  Company  resolved  to  pay  differences  in  export  duties  that  had  been  objected  to  by  several  Customs,  arising  from  future 
deliveries  of  crude  oil  commitments,  by  adhering  to  the  anticipated  moratorium  provided  for  in  Law  27,260.  This  action  allowed  the  abatement  of 
interest and cancellation of the applied fines underlying the substantial obligation. For this purpose, presentations were file in all pending administrative 
and judicial cases evidencing the payment of the export duties and, where appropriate, the request for remission of the fines applied under the provisions 
set forth in Law 27,260. The summary proceedings and other proceedings in which the application of a fine is the matter at issue when there were no 
export  duties  are  still  pending,  applying  in  that  case  the  fine  contemplated  in  article  954  clause  c),  which  amounts  to  400  as  of  the  date  of  this 
consolidated financial statements. 

On April 18, 2018, the Company was notified of the judgement rendered by the Federal Appeals’ Court No. IV which ruled that the fines imposed by 
the customs authority of Neuquén were condoned, due to the fact that there were no export duties, based on section 56 of Act No. 27,260. The Customs 
authority filed an extraordinary appeal before CSJN. The same decision was adopted in a judgment recently rendered in another case by the same Court 
of Appeals, which was also appealed to the CSJN. 

The Company, based on its opinion and that of its external advisors, believes the claim has no legal merit and that it has a strong case in defense of the 
approach adopted in the dispute mentioned above. 

28.b.5) Other claims 

Additionally,  the  Group  has  received  other  labor,  civil and  commercial claims  and  several claims  from  the  AFIP  and  from provincial and  municipal 
fiscal  authorities,  not  individually  significant,  which  have  not  been  accrued  since  Management,  based  on  the  evidence  available  as  of  the  date  of 
issuance of these consolidated financial statements, has assessed them to be possible contingencies.

29.a) Agreements of extension of concessions

Neuquén 

Loma La Lata - Sierra Barrosa Areas 

On December 28, 2000, through Decree No. 1,252/2000, the Argentine Federal Executive Branch (the “Federal Executive”) extended for an additional 
term of 10 years (until November 2027) the concession for the exploitation of Loma La Lata – Sierra Barrosa area granted to YPF. The extension was 
granted under the terms and conditions of the Extension Agreement executed between the Argentine Government, the Province of Neuquén and YPF on 
December 5, 2000. Under this agreement, YPF paid US$ 300 million to the Argentine Government for the extension of the concession mentioned above 
and committed, among other things, to define a disbursement and investment program of US$ 8,000 million in the Province of Neuquén from 2000 to

YPF SOCIEDAD ANONIMA
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2018, 2017 AND 2016

29. CONTRACTUAL COMMITMENTS (Cont.) 

During September 2013, and upon the fulfillment of certain precedent conditions (which included the granting of an extension of the Loma Campana 
concession  maturity  until  2048  and  the  unitization  of  that  area  with  the  sub-area  Loma  La  Lata  Norte),  Chevron  made  the  initial  payment  of  US$ 
300 million. 

On December 10, 2013, the Company and some of its subsidiaries and subsidiaries of Chevron successfully completed the pending documents for the 
settlement of the Investment Project Agreement, which enables the disbursement by Chevron of US$ 940 million, in addition to the US$ 300 million 
that such company has already disbursed. For such purposes, the Company and Chevron made the necessary contracts for the assignment in favor of 
Compañía de Hidrocarburo No Convencional S.R.L. (“CHNC”) of 50% of the exploitation concession Loma Campana, and supplementary agreements 
including the contract for the organization of the JO and the Joint Operating Agreement for the operation of Loma Campana, where YPF participates as 
area operator. 

The  Company  indirectly  holds  100%  of  the  capital  stock  of  CHNC,  but  under  the  existing  contractual  arrangements,  it  does  not  make  financial  or 
operative decisions relevant to CHNC and does not fund its activities either. Therefore, the Company is not exposed to any risk or rewards due to its 
interest in CHNC. Thus, as required by IFRS, the Company has valued its interest in CHNC at cost, which is not significant, and has not recorded any 
profit or loss for such interest for the years ended December 31, 2018, 2017 and 2016. 

Considering the rights that Chevron could exercise in the future over CHNC to access to the 50% of the concession and supplementary rights, and as a 
guarantee  for  such  rights  and  other  obligations  under  the  LC  Agreement,  a  pledge  over  the  shares  of  YPF’s  affiliate,  which  is  an  indirect  holder  of 
YPF’s interest in CHNC, has been made in favor of Chevron. 

In  this  context,  and  considering  that  YPF  is  the  Loma  Campana  area  operator,  the  parties  have  executed  a  Project  Obligations,  Indemnities  and 
Guarantee Agreement, by virtue of which the Company makes certain representations and guarantees in relation to the LC Agreement. This guarantee 
on  the  operation  and  management  of  the  Project  does  not  include  the  project’s  performance  or  return  on  investment,  both  at  the  exclusive  risk  of 
Chevron. 

Finally, other supplementary agreements and documents related to the LC Agreement have been signed, including: (a) the agreement for the allocation 
of certain benefits deriving from Decree No. 929/2013 from YPF to CHNC; (b) terms and conditions for YPF’s acquisition of natural gas and crude oil 
pertaining to CHNC for 50% of the interest in the Loma Campana area; and (c) certain agreements for the technical assistance of Chevron to YPF. 

During April 2014, YPF and certain of its subsidiaries and subsidiaries of Chevron, successfully completed the second phase of the LC Agreement and 
Chevron  has  confirmed  its  decision  to  continue  with  the  investment  project  in  unconventional  hydrocarbons  in  the  Loma  Campana  area,  thereby 
commencing the third phase of such project. The duration of this third phase will encompass the life of the project, until the expiration of the Loma 
Campana concession. 

During fiscal years 2018, 2017 and 2016, YPF and CHNC carried out transactions, among others, the purchases of gas and crude oil by YPF for 14,295, 
5,672 and 5,912, respectively. These transactions will be consummated in accordance with the general and regulatory conditions of the market. The net 
balance payable to CHNC as of December 31, 2018, 2017 and 2016 amounts to 2,064, 654 and 544, respectively.

Agreements for the development of the Chihuído de la Sierra Negra Sudeste– Narambuena area 

During  April  2014,  YPF  and  Chevron  signed  a  new  project  investment  agreement  with  the  objective  of  the  joint  exploration  of  unconventional 
hydrocarbons  in  the  Province  of  Neuquén,  within  the  area  Chihuido  de  la  Sierra  Negra  Sudeste  –  Narambuena.  The  investment  will  be  undertaken 
exclusively by, and at the sole risk of, Chevron. The investment will be disbursed in two stages. 

To  this  end,  the  Company  and  Chevron  entered  into  the  necessary  agreements  to  implement  the  assignment  to  Compañía  de  Desarrollo  No 
Convencional  S.R.L  (“CDNC”)  of  (a) a  50%  interest  in  the  Narambuena  Exploration  Project  Area  and  (b) a  7%  legal  interest  in  the  Exploitation 
Concession of Chihuido de la Sierra Negra in Neuquén and Mendoza. However, contractual rights of Chevron are limited to Narambuena Area, as YPF 
will hold 100% ownership of the conventional production and reserves outside the Project Area and Desfiladero Bayo field. On May 29, 2015, the first 
phase of the agreement was settled with the fullfilment of the relevant assignments.

In October 2017, Chevron decided to go ahead with the second phase of the project that consists of the drilling and completion of 43 horizontal wells in 
the  period  2018  –  2019.  The  Company  indirectly  holds  a  100%  interest  in  the  capital  stock  of  CDNC;  however,  as  pursuant  to  effective  contractual 
agreements, the Company neither exercises CDNC’s relevant financial and operating decision-making rights nor funds its activities, the Company is not 
exposed to risks and benefits for its interest in CDNC. Therefore, according to IFRS, the Company has valued its interest in CDNC at cost, which is not 
significant, and has not recorded any income (loss) for the said interest for the fiscal years ended December 31, 2018, 2017 and 2016.

30. MAIN REGULATIONS AND OTHER 

30.a) Hydrocarbon Law 

On October 31, 2014, the Argentine Republic Official Gazette published the text of Law No. 27,007, amending the Hydrocarbon Law No. 17,319. The 
most relevant aspects of the law are as follows: 

•

•

•

•

•

•

As regards exploration permits, it distinguishes between those with conventional and unconventional objectives, and between explorations 
in the continental shelf and in territorial waters, establishing the respective terms for each type. 

As  regards  concessions,  three  types  of  concessions  are  provided,  namely,  conventional  exploitation,  unconventional  exploitation,  and 
exploitation in the continental shelf and territorial waters, establishing the respective terms for each type. 

The terms for hydrocarbon transportation concessions were adjusted in order to comply with the exploitation concessions terms. 

As  regards  royalties,  a  maximum  of  12%  is  established,  which  may  reach  18%  in  the  case  of  granted  extensions,  where  the  law  also 
establishes the payment of an extension bond for a maximum amount equal to the amount resulting from multiplying the remaining proven 
reserves at the end of effective term of the concession by 2% of the average basin price applicable to the respective hydrocarbons over the 2 
years preceding the time on which the extension was granted. 

The extension of the Investment Promotion Regime for the Exploitation of Hydrocarbons (Decree No. 929/2013) is established for projects 
representing a direct investment in foreign currency of at least US$ 250 million, increasing the benefits for other type of projects. 

Reversion and transfer of hydrocarbon exploitation permits and concessions in national offshore areas is established when no association 
contracts subscribed with ENARSA to the National Secretariat of Energy exist. 

30.b) Hydrocarbon Sovereignty Regime – Decree No. 1,277/2012 

On  July 25,  2012,  the  executive  decree  of  Law  No. 26,741,  Decree  No. 1,277/2012,  was  published,  creating  the  “Regulation  of  the  Hydrocarbons 
Sovereignty Regime in the Argentine Republic”. Among other matters, the mentioned decree establishes: the creation of the National Plan of Investment 
in Hydrocarbons; the creation of the Commission for Planning and Coordination of the Strategy for the National Plan of Investment in Hydrocarbons 
(the  “Commission”),  which  will  elaborate  on  an  annual  basis,  within  the  framework  of  the  National  Hydrocarbon  Policy,  the  National  Plan  of 
Investment  in  Hydrocarbons;  the  National  Registry  of  Investments  in  Hydrocarbons  in  which  the  companies  undertaking  activities  of  exploration, 
exploitation, refining, transport and commercialization of hydrocarbons and fuels will have to register; and the obligation for the registered companies to 
provide  their  Plan  of  Investments  every  year  before  September 30,  including  a  detail  of  quantitative  information  in  relation  to  the  activities  of 
exploration, exploitation, refining, transport and commercialization of hydrocarbons and fuels according to each company. 

Additionally, the mentioned companies will have to provide their plans in relation to the maintenance and increase of hydrocarbons reserves, including: 
a)  an  investment  in  exploration  plan;  b)  an  investment  plan  in  primary  hydrocarbons  reserves  recovery  techniques;  and  c)  an  investment  plan  in 
secondary  hydrocarbons  reserves  recovery  techniques,  which  will  be  analyzed  by  the  Commission;  the  Commission  will  adopt  the  promotion  and 
coordination measures that may consider necessary for the development of new refineries in the National Territory, that may allow the growth in the 
local processing capacity in accordance with the aims and requirements of the National Plan of Investment in Hydrocarbons; in relation to prices, and 
accordingly to the Decree, for the purpose of granting reasonable commercial prices, the Commission will determine the criteria that will govern the 
operations in the domestic market. In addition, the Commission will publish reference prices of each of the components of the costs and the reference 
prices for the sale of hydrocarbons and fuels, which will allow to cover the production costs attributable to the activity and to reach a reasonable margin 
of profit. 

Not complying with the dispositions included in the Decree and supplementary rules may result in the following penalties: fine, admonition, suspension 
or deregistration from the registry included in section 50 of Law No. 17,319 or the nullity or expiration of the concessions or permits. Moreover, the 
mentioned decree abrogates the dispositions of the Decrees No. 1055/1989, 1212/1989 and 1589/1989 which set, among other matters, the right to the 
free disposition of hydrocarbon production.

30. MAIN REGULATIONS AND OTHER (Cont.) 

On December 29, 2015, the Executive Branch issued Decree No. 272/2015, resolving for the dissolution of the Commission and its Regulations, and 
also providing that the powers vested on the Commission were to be exercised by the MINEM. 

30.c) Investment Promotion Regime for the Exploitation of Hydrocarbons - Decree No. 929/2013 

Decree No. 929/2013 provides for the creation of an Investment Promotion Regime for the Exploitation of Hydrocarbons (the “Promotional Regime”), 
both conventional and unconventional, which will apply throughout the territory of the Republic of Argentina. Inclusion in the Promotional Regime may 
be  applied  for  by  subjects  registered  with  the  Hydrocarbon  Investments  National  Register  and  holding  hydrocarbon  exploration  permits  and/or 
exploitation  concessions  and/or  any  third  party  associated  and  together  with,  such  holders,  provided  they  file  with  the  Strategic  Planning  and 
Coordination  Commission  of  the  Hydrocarbon  Investments  Nation  Plan  created  by  Decree  No. 1,277/2012  a  “Hydrocarbon  Exploitation  Investment 
Project”  entailing  a  direct  investment  in  foreign  currency  of  at  least  US$  1,000 million,  computed  as  of  the  filing  of  the  Hydrocarbon  Exploitation 
Investment Project to be invested during the first five years of the Project (this amount was amended by the subsequent Law No. 27,007 to US$ 250 
million). Among the benefits to subjects comprised by the Promotional Regime, the following are highlighted: i) they will be entitled, subject to the 
terms of Law No. 17,319 and as from the fifth successive year of actual execution of their respective “Hydrocarbon Exploitation Investment Projects”, 
to freely sell to foreign markets 20% of their production of liquid and gaseous hydrocarbons produced under the said Projects, with a 0% rate for export 
duties, should these be otherwise applicable; ii) they will be entitled to free availability of 100% of any foreign currency obtained from export of the 
hydrocarbons mentioned in the preceding item, provided that the approved “Hydrocarbon Exploitation Investment Project” implies the entry of foreign 
currency  to  the  Argentine  market  of  at  least  US$  1,000 million  and  as  mentioned  hereinabove;  iii)  it  is  provided  that,  during  periods  where  national 
production is not enough to meet domestic supply needs under the terms of section 6 of Law No. 17,319, subjects included In the Promotional Regime 
will be entitled, as from the fifth year from approval and execution of their respective “Hydrocarbon Exploitation Investment Projects”, to obtain, in 
compensation for the percentage of liquid and gaseous hydrocarbons produced under such Projects available for export as mentioned herein above, an 
export  price  of  not  less  than  the  reference  export  price,  for  whose  determination  the  incidence  of  export  duties  otherwise  applicable  will  not  be 
computed. 

In  addition,  the  Decree  creates  the  figure  of  “Unconventional  Hydrocarbon  Exploitation”,  consisting  of  the  extraction  of  liquid  and/or  gaseous 
hydrocarbons through unconventional stimulation techniques applied in fields located in shale gas or shale oil, tight sands, tight gas and tight oil, and 
coal bed methane geological rock formations and/or characterized, generally, by the presence of low permeability rocks. In connection therewith, it has 
been  provided  that  subjects  holding  hydrocarbon  exploration  permits  and/or  exploitation  concessions  included  in  the  Promotional  Regime  will  be 
entitled  to  apply  for  an  “Unconventional  Hydrocarbon  Exploitation  Concession”.  In  addition,  holders  of  “Unconventional  Hydrocarbon  Exploitation 
Concessions”  who  in  turn  are  holders  of  an  adjacent  pre-existing  exploitation  concession,  may  apply  for  the  merging  of  both  areas  into  a  sole 
unconventional area, provided that due evidence is given of the geological continuity of the relevant areas. 

30.d) Withholding rates of hydrocarbon exports 

On September 4, 2018, Decree No. 793/2018 was published in the Official Gazette establishing, until December 31, 2020, an export duty of 12% on all 
goods under the tariff items of the Mercosur Common Nomenclature (“NCM”). This export duty will be capped at 4 Pesos per U.S. dollar of the taxable 
amount or official FOB price, as applicable. For goods other than primary products, the cap will be 3 Pesos per U.S. dollar of the taxable amount or 
official FOB price, as applicable.

30.e) Liquid hydrocarbons regulatory requirements 

Resolution No. 1,679/2004 of the Secretariat of Energy reinstalled the registry of diesel and crude oil export transactions created by Executive Decree 
No. 645/2002, and mandated that producers, sellers, refining companies and any other market agent that wishes to export diesel or crude oil to register 
such  transaction  and  to  demonstrate  that  domestic  demand  has  been  satisfied  and  that  they  have  offered  the  product  to  be  exported  to  the  domestic 
market.  In  addition,  Resolution  No. 1,338/2006  of  the  Secretariat  of  Energy  added  other  petroleum  products  to  the  registration  regime  created  by 
Executive Decree No. 645/2002, including gasoline, fuel oil and its derivatives, diesel, aviation fuel, asphalts, certain petrochemicals, certain lubricants, 
coke and petrochemical derivatives. Resolution No. 715/2007 of the Secretariat of Energy empowered the National Refining and Marketing Director to 
determine the amounts of diesel to be imported by each company, in specific periods of the year, to compensate for exports of products included under 
the regime of Resolution No. 1,679/2004; the fulfillment of this obligation to import diesel is necessary to obtain authorization to export the products 
included under Decree No. 645/2002. 

In  addition,  certain  regulations  establish  that  exports  are  subordinate  to  supplying  the  domestic  market.  In  this  way,  Resolution  No. 25/2006  of  the 
Secretariat of Domestic Commerce, issued on October 11, 2006, imposes on each Argentine refining and/or retail company the obligation to supply all 
reasonable diesel fuel demand, by supplying certain minimum volumes (which at minimum should be volumes supplied the year before plus the positive 
correlation between diesel demand and GDP accumulated from the month reference). The mentioned commercialization should be done without altering 
or affecting the normal operation of the diesel market. 

Additionally,  Rule  No.168/2004  requires  companies  intending  to  export  LPG  to  first  obtain  an  authorization  from  the  Secretariat  of  Energy,  by 
demonstrating that local demand was satisfied or that an offer to sell LPG to local demand has been made and rejected. 

In  January  2008,  the  Secretariat  of  Domestic  Commerce  issued  Resolution No.14/2008, whereby  the  refining  companies  were  instructed  to  optimize 
their production in order to obtain maximum volumes according to their capacity. 

Decree  No. 1,189/2012  of  the  National  Executive  Branch,  dated  July 17,  2012,  established  that  the  jurisdictions  and  entities  of  the  National  public 
Sector  included  in  section  8,  subsection  a)  of  Law  No. 24,156  (National  Administration,  formed  by  the  central  administration  and  the  decentralized 
agencies including the social insurance institutions) must contract with YPF the provision of fuels and lubricants for the fleet of official cars, boats and 
aircrafts, except in those cases which have the prior authorization of the Chief of the Cabinet of Ministers.

Agreements of local crude oil and fuel prices

In January 2017, oil producers and refiners reached an agreement for the transition to international prices of the Argentine hydrocarbon industry, which 
established proposed prices for the commercialization of crude oil on the domestic market in order to achieve parity with international markets during 
the  course  of  2017.  Notwithstanding  the  foregoing,  the  agreement  provided  for  the  power  of  either  party  to  abandon  the  agreement  during  its  term, 
which was also subject to compliance with certain variables such as the exchange rate or price of Brent crude oil within certain established parameters. 
During the last quarter of 2017, the price agreement was suspended because it considered this suspension in case the average international price of 10 
days exceeds the local price, but it also states that it may be restored if the average price of Brent crude is positioned below the local price for more than 
10 days. 

Since then, the market players –producers and refiners– began to freely agree on domestic crude oil prices, generally valid on a calendar-month basis 
and  linked  to the  Brent  international  benchmark,  while  maintaining  limits  on  the  exchange  rate.  Peso/US$  and  Brent’s  own  value,  depending  on  the 
capacity to transfer its price (expressed in US$/Bbl) to the prices of the products obtained from it –basically fuels (expressed in Peso/unit)– for their 
market sale.

30. MAIN REGULATIONS AND OTHER (Cont.) 

However, and in light of the current domestic macroeconomic situation, e.g. the substantial increase in crude oil price and the short-term exchange rate, 
among other factors, on May 8, 2018, the MINEM and the refining companies (among them, YPF) entered into a price stabilization agreement with a 
compensatory account, whereby the refining companies undertook not to modify fuel prices (net of taxes) in force as of such date during the months of 
May and June, in order to benefit the general economic interest which, in turn, would have potential effects on the Company. 

Moreover, the agreement included the creation of a compensatory account which incorporated the distortion in prices in terms of international reference 
prices  accrued  as  of  the  date  of  the  agreement,  together  with  the  adjustments  resulting  from  additional  cost  variations  (crude  oil,  exchange  rate  and 
biofuel price) which would not be transferred to prices during the months of May and June. The agreement set forth that such compensatory account 
would be transferred to the market through price increases during the second semester or, otherwise, the MINEM undertook the commitment to find 
mechanisms so that the refining companies may recover such difference. 

On June 1,  2018,  the  MINEM  and  the  refining  companies (among  them YPF)  entered  into  a supplementary  agreement  that considered to  establish  a 
Brent reference price for crude oil purchases among refining and producing companies for the months of May (66 US$/bbl), June (67 US$/bbl) and July 
(68 US$/bbl), 2018, and an increase in final prices of gasolines and gasoil of up to 5% and 4.5%, respectively, as from June 2, 2018, which included the 
variation in the liquid fuel tax, the carbon dioxide tax and the prices of biofuel prevailing as from that date. Additionally, an increase in an amount of up 
to 3% in the consumer prices of fuels, net of any variation in taxes, was expected to take place during the month of July. 

On June 29, 2018, in face of the volatility and significant change in the variables that were the basis for the agreements above mentioned, YPF informed 
the  MINEM  on  the  decision  to  implement  as  from  July 1,  2018,  the  applicable  commercial  policies  according  to  the  changes  in  the  variables  stated 
above, both for determination of sales prices of its products and of those for the purchase of crude oil, in accordance with the evolution of the general 
business environment and the evolution of customers in particular, consistent with the regulatory framework and current provisions. Consequently, the 
aforementioned agreements have ceased to be in force for YPF as from June 30, 2018; however, the Company has submitted the resulting amounts in 
the compensatory account to the relevant authorities, which represent contingent rights. 

On December 6, 2018, YPF requested the SGE to set the guidelines for the implementation of the mechanism to recover the costs not transferred to fuel 
prices for the period contemplated under the Agreement, having received no response to the date of issuance of these consolidated financial statements. 

30.f) Regulatory requirements for natural gas 

• Mechanisms for allocating the demand for natural gas

SE Resolution No. 599/2007 - ENARGAS Resolution No. 1410/2010 

SE Resolution No. 599/2007 (the “Resolution”) stands out which was issued on June 14, 2007. This Resolution approved an agreement with natural gas 
producers regarding the natural gas supply to the domestic market during the period 2007 through 2011 (the “Agreement 2007-2011”) which guaranteed 
the normal supply of the natural gas domestic market during the period 2007 through 2011, considering the domestic market demand registered during 
2006 plus the growth of residential and small commercial customer consumption (the “Priority Demand”). According to the Resolution, the Producers 
had  to supply  a  part  of the Priority Demand according to  certain  percentage  determined for  each  producer based  upon  its  share  of  production  of  the 
previous years. Considering that the Resolution provided for the continuity of the regulatory mechanisms that affect the exports, YPF filed an appeal 
against the resolution and expressly stated that the execution of the Agreement 2007-2011 did not mean any recognition by YPF of the validity thereof.

Additionally, on October 4, 2010, the Official Gazette published ENARGAS Resolution No. 1410/ 10 that approved the “Supplementary Procedure for 
Gas  Requests,  Confirmations  and  Control”  which  set  out  new  rules  for  natural  gas  dispatch  applicable  to  all  participants  in  the  natural  gas  industry, 
imposing new and more severe regulations to the producers’ availability of natural gas. By virtue of these procedures, distributors were authorized to 
request  all  the  natural  gas  necessary  to  cover  the  Priority  Demand  even  in  the  case  of  natural  gas  volumes  that  exceed  those  that  the  Secretariat  of 
Energy  would  have  allocated  by  virtue  of  the  Agreement  ratified  by  the  Resolution  No. 599/07.  The  Company’s  appeal  against  Resolution 
No. 1410/2010 was rejected. As of the date of issuance of these consolidated financial statements, this Resolution has not been repealed. ENARGAS 
Resolution No. 124/18 published on June 29, 2018, approved the restated text of the internal regulations of dispatch centers applicable as of June 30, 
2018 and repealing ENARGAS Resolution No. 1410/10. 

MINEM  Resolution  No.  89/16  -  ENARGAS  Resolution  No. 3833/16  –  ENARGAS  Resolution  No. 4502/17  –  ENARGAS  Resolution  No. 59/18  – 
ENARGAS Resolution No. 124/18 – ENARGAS Resolution No. 302/18 

On June 1, 2016, the MINEM published Resolution No. 89 whereby: 

a)

b)

ENARGAS was instructed to develop a procedure that modifies and supplements the one established in ENARGAS Resolutions 
No. 716/1998 and 1410/2010 and establishes daily operation conditions of the Transportation and Distribution Systems. 

It was decided that the volumes that may be requested by the Distributors to supply the priority and fixed demand which in case of 
contracting the natural gas to such destination with a natural gas producer, will reduce the requirement of natural gas to said producer as set 
forth in Resolution 1410/2010 to the extent of the contracted volume. 

According  to  this  Resolution,  ENARGAS  Resolution  I/3833  was  issued  on  June 5,  2016,  which  approves  the  “Supplementary  Procedure  for  Gas 
Requests, Confirmations and Control”. 

The  purpose  of  the  Procedure  is  to  establish  the  transition  mechanism  and  application  criteria  for  the  administration  of  the  natural  gas  dispatch  to 
preserve the operation of the transportation and distribution systems giving priority to the consumption of the Priority Demand in cases of supply crisis 
and/or emergencies which may put at risk the normal provision of the natural gas public service or which may affect the provision of another public 
service. 

The  new  Procedure  establishes  that  each  day  the  Distribution  Service  Providers  will  request  in  the  programming  computer  systems  of  the  Transport 
Companies  for  the  operational  day  n  +  1,  with  first  priority,  the  natural  gas  necessary  to  supply  the  Priority  Demand,  based  on  their  consumption 
estimate and in accordance with the contracted transport capacity and its supply agreements. 

The confirmation of natural gas in the TSEP for Priority Demand will have priority over other segments. The confirmation of gas for segments other 
than  the  Priority  Demand  will  maintain  the  confirmation  priority  established  by  the  Producer  in  the  respective  contracts  with  direct  consumers  (or 
Marketers), which will be informed to Transportation and Distribution Service Providers. 

The transportation nomination of each Distribution Service Provider will give priority to the supply of their Priority Demand over any other user of that 
Provider. 

The Providers of the Transportation and Distribution Service that verify that the transportation capacity is not sufficient to supply the Priority Demand 
must summon the Emergency Committee, chaired by the president of ENERGAS, who will procure the means to allocate the volumes in the emergency 
situation. 

On June 6, 2017 ENARGAS Resolution No 4,502/17 was issued which approved the Procedure for the administration of the office in the Emergency 
Executive Committee (“EEC”), modifying the procedure for the delivery request and gas confirmations which were approved by ENARGAS Resolution 
No. 3,833/16  and  provided  for  measures  and  criteria  to  be  adopted  in  a  supply  crisis  of  the  Priority  Demand  for  Natural  Gas  declared  by  the 
Transportation Companies, Distribution Companies or the ENARGAS. 

Among such measures, it was provided that the EEC or (if the EEC disagrees to it) the ENARGAS, will define the way in which the Priority Demand 
will be supplied considering the quantities of natural gas available in each basin for each producer and discounting the amounts contracted to supply the 
Priority Demand.

On May 18, 2018 ENARGAS Resolution No. 59/18 was published, approving the Temporary Procedure for Shipment Management in the Emergency 
Executive Committee (EEC), effective until the end of winter 2018. The EEC will be composed of at least one representative of the Transporters, the 
Providers and each carrier which, due to their geographical location and their respective demand have or may have incidence to resolve the situation. It 
will  be  chaired  by  a  representative  of  the  relevant  Transportation  Company  and  the  decisions  agreed  in  the  EEC  will  be  mandatory  for  all  Active 
Subjects of the Gas Industry. 

On  June 29,  2018,  ENARGAS  Resolution  No. 124/2018  was  published  in  the  Official  Gazette  which  (i) approves  the  amended  and  restated  internal 
regulations  for  dispatch  centers  as  from  June 30,  2018;  (ii)  derogates  ENARGAS  Resolutions  No. 1410/10,  3833/16  and  4502/17;  (iii)  sets  forth  its 
presumption  that  there  are  no  observations  by  ENARGAS  to  the  proposed  rescheduling  made  by  the  Transportation  companies  if  there  is  no 
communication to the contrary within 1 hour after it has been requested; and (iv) sets forth that the Temporary Procedure for Shipment Management in 
the Emergency Executive Commitee shall be applicable during the winter of 2018. 

On October 18, 2018 ENARGAS Resolution No. 302/2018 was published, which, considering that not all of the gas supply contracts for the Priority 
Demand  between  Producers  and  Distribution  Licensees  had  been  executed,  extended  the  effective term  of  ENARGAS  Resolution  No. 59/18  for  180 
calendar days as from October 1, 2018. 

Terms and Conditions for the Distribution of Natural Gas through Networks 

Under  the  energy  sector  normalization  process,  the  MINEM  called  on  natural  gas  producers  (including  YPF)  and  ENARSA  to  establish  the  basic 
conditions  that  will  constitute  the  framework  for  the  supply  agreements  to  be  executed  for  Natural  Gas  distribution  as  of  January 1,  2018.  In  the 
meeting, MINEM informed that given the expiration of the extension period established in Law No. 27,200 regarding the public emergency that began 
in 2002, Law No. 24,076 regained effectiveness, which sets forth that the price of natural gas supply agreements will be the price resulting from the free 
interaction of supply and demand. 

In this context, on November 29, 2017, natural gas producers (including YPF) and ENARSA, at the request of the MINEM, subscribed the “Terms and 
Conditions for the Provision of Natural Gas to Gas Distributors through Networks” (the “Terms and Conditions”). 

The Terms and Conditions establish the basic guidelines to assure the adequate supply of natural gas to the Distributors, and consequently to residential 
and commercial final consumers. Moreover, they establish the continuity of the gradual and progressive path of reduction of subsidies, all within the 
framework of the  process of normalization  of the  natural gas  market, which occurs  within the  period of validity of such Terms and Conditions until 
December 31, 2019 considered as the “transition period” until the normalization indicated above. 

The guidelines established in the Terms and Conditions include, among others, the recognition of the right to transfer to the gas tariff the cost of gas 
acquisition  paid  by  users  and  consumers;  establishes  the  available  volumes  that  each  producer  and  each  basin  must  make  available  daily  to  the 
distributors for each month, who may express their lack of interest before a certain date set forth in the Terms and Conditions; establishes penalties for 
non-compliance for any of the parties regarding their obligation to deliver or take gas; establishes gas prices for each basin for the next two years, in 
U.S. dollars, the parties being able to set prices lower than those established under the applicable free negotiations; establishes payment guidelines for 
the  purchases  made  by  the  Distributors  to  producers;  ENARSA  assumes  the  obligation  to  supply  the  demand  corresponding  to  areas reached  by  the 
subsidies of residential gas consumption contemplated in article 75 of Law 25,565 (corresponding to the areas of lower price of residential gas charged 
to users and consumers), during the period of transition. 

The  Terms  and  Conditions  constitute  the  terms  and  conditions  to  consider  in  the  negotiations  of  their  respective  individual  agreements,  without  this

30. MAIN REGULATIONS AND OTHER (Cont.) 

As  a  consequence  of  the  exchange  rate  variation,  natural  gas  producing  and  distribution  companies  began  a  renegotiation  process  for  the  special 
agreements  executed  pursuant  to  the  Terms  and  Conditions,  with  prices  denominated  in  U.S.  dollars.  The  renegotiation  process,  still  underway, 
comprises two major issues: i) the payment of debts arising from differences between the exchange rate at which distribution companies actually paid 
gas purchases and the exchange rate contractually provided (period April – September 2018), and ii) the gas price to be applied to the period October – 
December 2018. 

On October 5, 2018, Resolution No. 20/2018 was published, establishing that in relation to differences between the price of gas provided in the contracts 
and the price of gas recognized in the final tariffs of distribution companies, valued for the quantity of gas purchased from April 1 to September 30, 
2018, the ENARGAS would instruct distribution companies to recover the credit in favor of producers on a separate line in the invoice to be issued to its 
users,  in  24  installments  from  1 January,  2019.  However,  SGE  Resolution  No. 20/2018  was  later  repealed  by  Resolution  No. 41/2018  published  on 
October 16, 2018, alleging opportunity issues for such implementation. 

On November 16, 2018, by Decree No. 1053/18, published in the Official Gazette, the Argentine Government decided to assume the payment of the 
daily  differences  accumulated  on  a  monthly  basis  between  the  price  of  gas  purchased  by  Distributors  and  the  price  of  natural  gas  included  in  tariff 
schemes effective  from  April 1, 2018 to March 31,  2019, exclusively generated due to exchange  rate  variations and corresponding  to the natural  gas 
volumes delivered in that same period. The conditions are as follows: 

•

•

•

30 monthly consecutive installments as from October 1, 2019, which will be determined by using the BNA effective interest rate for 30-day 
deposits in Argentine currency (“electronic board”). 

The installments will be collected by Distributors, which will immediately pay the Producers. 

Distributors and Producers must adhere to the system and expressly waive any action or complaint. 

As of the date of issuance of these consolidated financial statements, the complementary regulations for the application of the foregoing conditions for 
the distributors and producers are pending issuance by the ENARGAS. 

Besides, Decree No. 1053/18 established that since April 1, 2019, contracts between natural gas producers and distributors shall provide that the higher 
cost due to exchange rate variations during each seasonal period shall never be transferred to natural gas full-service users. 

On February 12, 2019, ENARGAS Resolution No. 72/2019 published in the Official Gazette, approved the methodology for transferring the gas price to 
tariffs and the general procedure to calculate the accumulated daily differences, applicable from April 1, 2019, which established, among other aspects, 
that for the purpose of transferring the gas price agreed in U.S. dollars to tariffs, the ENARGAS will define the exchange rate to be considered for the 
conversion into Pesos based on the average selling exchange rate of the BNA (foreign currencies) effective between the 1st and 15th day of the month 
immediately preceding the beginning of each seasonal period, or the exchange rates established in the contracts should the rates contemplated therein be 
lower.

New natural gas exports

National  Decree  No. 893/2016,  dated  July 25,  2016,  determined  that  the  MINEM  is  empowered  to  regulate  the  awarding  of  export  permits  for  the 
following  purposes:  (i) provide  assistance  in  natural  gas  emergency  cases  from  foreign  countries;  and  (ii) replace  the  natural  restrictions  of  local 
transportation through the use of external transportation infrastructure to facilitate natural gas transportation within the Argentine market and allow an 
increase in local production. 

On January 8, 2017, the export duties on hydrocarbon exports established by Law No. 26,732 ceased to be applicable. Thereafter, there are no export 
duties on natural gas exports.

30. MAIN REGULATIONS AND OTHER (Cont.) 

On  January 13,  2017,  MINEM  Resolution  No. 8/2017  was  published,  which  regulated  Decree  No. 893/2016,  establishing  a  special  procedure  for 
granting natural gas export permits subject to re-import commitments. The resolution is applicable for two types of exports; (i) those aimed at providing 
assistance in emergency cases (“Exports for Assistance”); and (ii) Exports required to make up for internal transport restrictions in order to allow both 
the use of infrastructure from neighboring countries to facilitate natural gas transportation to Argentine domestic market and the increase of domestic 
production (“Exports for Transportation Restriction”). The beneficiaries of both types of permits will be liable for the damages that might be caused to 
the Argentine natural gas supply system in the event of non-compliance with their re-import obligations as and when agreed and the costs of the import 
that the National Government must make to replace the exported gas which was not re-entered, with a penalty of 50% of such costs. Such permits would 
be extended for a maximum period of two years and will be subject to a possible termination if the public interest makes it advisable for the domestic 
market offer in accordance with MINEM criteria. 

On November 27, 2017, Decree 962/2017 was published which, among other aspects, modifies Art. 3 of the Regulatory Decree of the Law No. 24,076, 
establishing the following principles for export authorizations: 1) that the authorizations will be issued by the MINEM once the applications have been 
evaluated; 2) the export agreements that involve the construction of new facilities and / or new connections to the gas pipelines, or the use of any of the 
existing systems, or other transportation alternatives, will be approved by the MINEM with the intervention of ENARGAS; 3) the authorizations issued 
by the MINEM may provide for the export of surplus gas up to the amounts established therein, provided they are subject to interruption when there are 
internal supply problems. In such case, we would not be required to obtain the approval for each export of surplus amounts; instead, we would only be 
required  to  submit  to  the  ENARGAS,  for  informative  purposes  only,  the  respective  agreement  which  allows  us  to  interrupt  deliveries  without  any 
penalties. 

The modifications introduced by Decree No. 962/2017 do not modify the regime of temporary export permits, provided for in Decree No. 893/2016. 

On August 22, 2018, MINEM Resolution No. 104/2018, later modified by SGE Resolution No. 9/2018, was published in the Official Gazette, which: i) 
established a new Procedure to Obtain Natural Gas Export Licenses; ii) abrogated Resolution No. 299/98 issued by the former Secretariat of Energy, as 
amended, and established that export licenses granted under the repealed regulation would be subject to the Procedure to Obtain Natural Gas Export 
Licenses; iii) abrogated Resolution No. 131/01 issued by the former Secretariat of Energy and Mining, and its amendments; iv) abrogated Resolution 
No. 265/04  issued  by  the  former  Secretariat  of  Energy  and  Mining,  and  its  amendments,  v)  abrogated  Resolution  No. 883/05  issued  by  the  former 
Secretariat of Energy, as amended; vi) abrogated Resolution No. 8/17 issued by the former MINEM, as amended; and vii) delegated to Sub-secretariat 
of Hydrocarbon Resources the tasks related to this new Procedure. 

Resolution No. 104/2018 provided that in the case of export requests from a project included in MINEN Resolution No. 46-E/2017 (Unconventional 
Gas Production Stimulus Program), the quantities of gas would not be computed as part of and/or within the production included under the mentioned 
Program. 

On September 4, 2018, Decree No. 793/2018 was published in the Official Gazette imposing export duties on various goods, including natural gas. This 
decree set forth a 12% export duty on natural gas exports, which may not exceed 4 Pesos per each U.S. dollar of the taxable amount or official FOB 
price, as applicable. See Note 30.d. 

On  December 4,  2018,  Law  No. 27,467  of  the  Budget  of  the  National  Administration  for  the  Year  2019  was  published.  Sections  81  and  82  thereof 
respectively establish i) that the PEN may fix export duties until December 31, 2020 which rate may not exceed 30% of the taxable value or the official 
FOB price, with a maximum limit of 12 % for those goods that were not subject to export duties as of September 2, 2018 or that were taxed with a 0% 
rate as of that date, and ii) that Decree No. 793/18 continues in full force and effect.

Trust Fund to finance natural gas imports

On November 27, 2008 through Executive Decree No. 2067/08, a trust fund was created to finance imports of natural gas for its injection in the national 
gas  pipeline  system  when  necessary  to  satisfy  the  domestic  demand.  The  trust  fund  is  financed  through  the  following  mechanisms:  (i) diverse  tariff 
charges  paid  by  users  of  transportation  services  and  regularly  distributed,  gas  consumers  receiving  gas  directly  from  producers,  and  companies 
processing natural gas; (ii) special credit programs that may be agreed upon with national or international organizations; and (iii) specific contributions 
assessed by the Secretariat of Energy on the participants in the natural gas industry. This Decree has been object of diverse judiciary claims, and judges 
from all over the country have issued precautionary measures for suspension of its effects, grounded on the violation of the principle of legality on tax 
matters.  On  November 8,  2009,  ENARGAS  published  Resolution  No. 1982/11  that  adjusted  the  tariff  charges  established  by  Executive  Decree 
No. 2067/08 to be paid by users as from December 1, 2011. 

On November 24, 2011, ENARGAS passed Resolution No. 1991/2011, enlarging the number of users obliged to pay tariff charges, including residential 
services, natural gas processing, industrial premises and electric power plants, among others; this has affected the operations of the Company, and has 
had  a  significant  impact  on  our  joint  subsidiary  companies,  all  of  which  have  filed  appeals  against  the  mentioned  resolution.  For  its  part,  YPF  has 
challenged these resolutions and rejected the charge invoice made by Nación Fideicomiso. On April 13, 2012, YPF obtained a precautionary measure 
related to the El Portón processing plant, suspending the effects of these resolutions in relation to that plant until a decision on the administrative appeals 
filed by YPF had been reached. 

In November 2012, Law No. 26,784 was passed which granted legal hierarchy, since such date, to the decisions enacted by the Executive Branch and 
ENARGAS, in relation to the charge. Dated December 11, 2014, the CSJN pronounced the “Alliance” judgment, deciding that the charge created by 
decree 2067/2008 a tariff charge and not a tax, and thus not subjected to the principle of tax legality. However, the Court left open the possibility of 
eventual claims or defenses in cases different from the claims raised in the “Alliance” judgment. 

In particular, the application of the above mentioned tariff charge produces an impact so significant in Mega operations that, if not favorably resolved, 
Mega  could  have  in  the  future  serious  difficulties  continuing  its  business.  On  October 27,  2015,  the  CSJN  issued  a  resolution  on  the  motion  for 
protection of constitutional rights filed by Mega (for the period until the enactment of the 2013 Budget Enactment Law No. 26,784) providing that the 
charge under “Decree 2067/08” was unconstitutional and not applicable to Mega. 

On  April 1,  2016  the  MINEM  issued  Resolution  No. 28/2016,  which,  among  others,  revoked  resolutions  passed  by  the  former  Ministry  of  Federal 
Planning, Public Investment and Services under Section 6 of Decree No. 2067/2008 and Section 7 of Resolution No. 1,451/2008 of the aforementioned 
Ministry related to the assessment of tariff charges, which instructs the ENARGAS to take the necessary measures to cease applying those charges in the 
bills issued to users. 

In April 2018 and regarding “Decree 2067/08” on tariff charges, the Federal Administrative Court No 11 passed judgement on the unconstitutionality 
action  filed  by  Mega  (for  the  period  after  the  Budget  Act  for  2013  No  26,784),  which  admitted  the  complaint  and  declared  the  unconstitutionality, 
regarding Mega, of sections 53 and 54 of the law referred to above. Such first instance judgement took effect since it was not appealed by the Argentine 
Government.

Natural Gas Additional Injection Stimulus Programs

On  December  2012,  YPF  and  other  gas  producing  companies  of  Argentina  agreed  with  the  Planning  and  Strategic  Coordination  Commission  of  the 
National  Plan of  Hydrocarbon  Investments (the “Commission”)  to establish  an  incentive  scheme  for  the  Additional  Injection  (all  gas  injected  by  the 
companies  above  certain  threshold)  of  natural  gas.  On  February 14,  2013  Resolution  No. 1/2013  of  the  Commission  was  published  in  the  Official 
Gazette. This resolution formally creates the “Natural Gas Additional Injection Stimulus Program”.

AS OF DECEMBER 31, 2018, 2017 AND 2016

30. MAIN REGULATIONS AND OTHER (Cont.) 

Under this regulation, gas producing companies were invited to file projects for increasing total natural gas injection (“the projects”) to the Commission, 
in order to receive a price of US$ 7.50/MMBtu for all gas injected in excess (above the base injection level of each company). The Projects will comply 
with minimum requirements established in Resolution No. 1/2013, and will be subject to approval consideration by the Commission. The Projects have 
a  maximum  term  of  five  (5) years,  renewable  at  the  request  of  the  beneficiary,  and  subject  to  the  decision  of  the  Commission.  If  the  beneficiary 
company,  for  a  certain  month,  does  not  reach  the  compromised  production  increase  of  its  project,  approved  by  the  Commission,  it  will  have  to 
compensate its failure to achieve the minimum total injection committed in such Project. Resolution No. 60/2013, regulated by Resolution No. 83/2013, 
called Natural Gas Additional Injection Stimulus for Companies with Reduced Injection” established a similar program for the companies that failed to 
comply with the requirements of Resolution No. 1/2013 and those that had failed to register in time under such Resolution. The price to be paid under 
the program established in Resolution No. 60/2013 varies between US$ 4.00/MMBtu and US$ 7.50/MMBtu, according to the highest production curve 
reached by the beneficiary company under the program. 

On  September 29,  2015,  Resolution  No. 185/2015  was  published  in  the  Official  Gazette  regulating  the  so-called  Natural  Gas  Injection  Stimulus  for 
Companies without Injection in favor of those producers which do not have a previous record of natural gas injection the beneficiary companies will 
receive a compensation resulting from the difference between US$ 7.50/MMBtu and the price received for the sale of the natural gas in the market. Such 
compensation shall be received only for natural gas originating in areas whose production rights will have been acquired from companies registered with 
any of the two previous programs and provided that during the period in which the transferor will have calculated its “base injection”, according to its 
program, the injection of the area operated by the current beneficiary –transferee– will have been null. 

On May 20, 2016, Decree No. 704/2016 was published, whereby the debt was converted into pesos under the Stimulus Plan for Surplus Natural Gas 
Injection, the Stimulus Plan for Natural Gas Injection Program for Companies with Reduced Injection and those derived from the Supply of Propane 
Gas for Undiluted Propane Gas Distribution Networks Agreement at the exchange rate in force at the end of each period, and Argentine National Bonds 
were granted in U.S. dollars at an interest rate of 8% per annum maturing in 2020 (“BONAR 2020 US$”) for the cancellation thereof. 

The sale of these BONAR 2020 US$ was restricted according to the letters of accession; therefore, until and including December 2017, the Group could 
not  sell  on  a monthly basis  more  than 3%  of  the  aggregate  amount of  the  BONAR  2020  US$ received.  In addition, during  the  months in  which  the 
Group did not exercise its right to sell the BONAR 2020 US$ up to the above-mentioned percentage, it could accumulate the unused percentage for its 
sale in subsequent months. In no event could the sale in a single month of the accrued balances exceed 12% of the total BONAR 2020 US$ received. 

In  order  to  request  the  cancellation  of  outstanding  payments,  beneficiaries  had  to  sign  letters  of  accession  and  submit  them  to  the  Hydrocarbon 
Resources Secretariat of the MINEM. YPF filed the letters of accession and reserved the right to claim the exchange differences and interest. 

On  July 13,  2016,  the  Group  received,  under  the  Natural  Gas  Additional  Injection  Stimulus  Program,  BONAR  2020  US$,  with  a  face  value  of  US$ 
630 million. In addition, on September 21, 2016, under the Supply of Propane Gas for Undiluted Propane Gas Distribution Networks Agreement, the 
Group received BONAR 2020 US$, with a face value of US$ 12 million. 

These programs had a maximum duration of 5 years, and terminated on December 31, 2017, without having been renewed. 

On April 3, 2018, MINEM Resolution No. 97/2018 was published in the Official Gazette approving the procedure (the “Procedure”) for the cancellation 
of  compensations  pending  settlement  and/or  payment  under  the  Natural  Gas  Surplus  Injection  Stimulus  Program,  Natural  Gas  Surplus  Injection 
Stimulus Program for Companies with Reduced Injection and the Stimulus Program for New Natural Gas Projects, to which the beneficiary companies 
may adhere.

Each company may choose to receive compensation under the approved procedure stating its accession within 20 business days from the publication of 
the resolution. It is required that the company waive any rights, actions, remedies, appeals, and claims, either administrative and/or judicial, based on the 
Program, except for: i) the objection to the administrative acts that determine the relevant compensation according to the Procedure; and ii) the failure to 
comply with the payments provided for under the Procedure for a minimum amount of 3 installments, at the option of each beneficiary Company. 

The  debt  amount  will  be  determined  as  follows:  85%  of  the  U.S.  dollar  amount  will  be  calculated  according  to  the  exchange  rate at  the  time  of  the 
injection (“Program exchange rate”) and 15% of the U.S. dollar amount but devalued (multiplied by the quotient between the Program exchange rate 
and  the  exchange  rate  corresponding  to  the  payment  dates  of  the  compensation  resolutions  already  issued  or  the  date  of  publication  of  Resolution 
97/2018, as applicable). The debt will begin to be canceled as of January 2019 in 30 monthly and consecutive installments, in Pesos, at the monthly 
average reference rate set forth in the Communication A 3500 of the BCRA (Wholesale) of the month preceding each installment. 

On May 3, 2018, the Group adhered to the aforementioned Procedure. 

As a consequence of the foregoing, the Group recorded a gain of 804 included in the item “Net financial results”. 

On December 4, 2018, Law No. 27,467 of the Budget of the National Administration for the year 2019 was published. Section 55 thereof authorized the 
issue of public debt instruments for up to US$1,600 million, for the cancellation of compensations of the Gas Plan I for the year 2017 (in accordance 
with the provisions set forth in Resolution No. 97, dated March 28, 2018 of the former MINEM) 

SGE Resolution No. 54/19, published on February 21, 2019, partially amended Resolution No. 97/2018, adjusting it to the payment method defined in 
section  55  of  Law  No. 27,467.  It  established,  among  other  things,  that  in  order  to  request  cancellation  according  to  this  mechanism,  beneficiary 
companies  are  required  to  express  their  consent  within  ten  days  from  notice  receipt,  and  that,  upon  accession  to  the  aforementioned  cancellation 
procedure, they had to waive any rights, actions or claims in relation to the programs, the administrative compensation acts and the payment orders they 
have issued. 

Joint Resolution No. 21/19 issued by the Secretariats of Finance and Treasury published on February 28, 2019 in the Official Gazette, established the 
issuance  of  the  “Natural  Gas  Program  Bonds”  for  an  amount  of  up  to  US$  1,600 million,  maturing  on  June 28,  2021,  to  be  repaid  in  29  monthly 
consecutive installments. 

Also on February 28, 2019, the SGE notified YPF the amount of the compensations included, estimated in compliance with Resolution No. 97/18 for a 
total amount of US$ 758 million. 

On March 1, the Company presented its accession letter to the SGE in compliance with SGE Resolution 54/19.

Stimulus Program for New Natural Gas Projects

On May 18, 2016, MINEM Resolution No. 74/2016 created the “Natural Gas New Projects Stimulus Program” in order to foster natural gas production 
for  those  companies  submitting  new  natural  gas  projects,  provided  they  are  not  beneficiaries  of  the  “Natural  Gas  Additional  Injection  Stimulus 
Program” or the “Natural Gas Injection Stimulus for Companies with Reduced Injection”, created by Resolutions No. 1/2013 and 60/2013, respectively, 
of the former Strategic Planning and Coordination Commission of the Hydrocarbon Investments National Plan. 

The submission of new projects, which must be approved by the Hydrocarbon Resources Secretariat, may obtain a stimulus price of US$ 7.50/MMBtu. 

Moreover, the “Natural Gas Injection Stimulus for Companies without Injection”, created by Resolution No. 185/2015 of the former Strategic Planning 
and Coordination Commission of the Hydrocarbon Investments National Plan has been abolished, but any projects submitted under such program which 
are pending approval must be evaluated under the “Natural Gas New Projects Program”. 

The “Natural Gas New Projects Program” will be effective as from the publication of the relevant resolution in the Official Gazette (May 19, 2016) until 
December 31, 2018.

Stimulus Program for Investments in Natural Gas Production Developments from non-conventional Reservoirs

On March 6, 2017, MINEM Resolution No. 46-E/2017 was published in the Official Gazette, which created the “Investment in Natural Gas Production 
from Non-Conventional Reservoirs  Stimulus Program” (hereinafter the “Program”), established in order to stimulate investments in natural gas from 
non-conventional reservoirs in the Neuquina basin, and in effect as of its publication until December 31, 2021. 

The Resolution establishes compensation for the volume of non-conventional gas production from concessions located in the Neuquina Basin included 
in  the  Program,  for  which  such  concessions  must  first  have  a  specific  investment  plan  approved  by  the  province’s  application  authority  and  the 
Secretariat of Hydrocarbon Resources. 

The compensation will be determined by deducting from the effective sales price obtained from sales to the internal market, including conventional and 
non-conventional  natural  gas,  the  minimum  sales  prices  established  by  the  Resolution  each  year,  multiplied  by  the  volumes  of  production  of 
non-conventional  natural  gas.  The  minimum  prices  established  by  the  Resolution  are  US$  7.50/MMBtu  for  2018,  US$  7.00/MMBtu  for  2019,  US$ 
6.50/MMBtu for 2020 and US$ 6.00/MMBtu for 2021. 

The compensation from the Program will be distributed, for each concession included in the Program, as follows: 88% to the companies and 12% to the 
province corresponding to each concession included in the Program. 

On  November 2,  2017,  MINEM  Resolution  419-E/2017  was  published  and  its  Annex  replaces  the  similar  Annex  of  Resolution  46-E/2017. The  new 
resolution modifies the previous one in the following aspects: 

a)

b)

c)

It defines that the Initial Production to be calculated will be the “monthly mean Non-Conventional Gas production assessed for the period between 
July 2016 and June 2017”. It also states that the Production Included, to the effect of the compensation, will be i) for the concessions with Initial 
Production lower than 500,000 m3/day, the total monthly production of Non-Conventional Gas coming from such Included Concession, to which 
the requesting company is entitled, and ii) for the concessions with Initial Production higher than 500,000 m3/day, the total monthly production of 
Non-Conventional Gas coming from such Included Concession, to which the requesting party is entitled, discounting the Initial Production. 

It modifies the definition of Effective Price, previously defined as “the average price weighted by volume of total natural gas sales of each 
company in the domestic market”, to “the average price weighted by volume of total natural gas sales in the Argentine Republic that will be 
published by the Secretariat of Hydrocarbon Resources”, regulating the guidelines to be followed for such calculation. 

A requirement to qualify for the Program is included, that is, that the investment plan submitted for each concession reaches a yearly mean 
production, in any consecutive period of twelve months before December 31, 2019, equal to or higher than 500,000 m3/day, and the obligation to 
reimburse the amounts of the compensation received (updated to reflect interest) corresponding to the concessions that do not reach the above 
mentioned production level, with the possibility that the Secretariat of Hydrocarbon Resources may require filing a surety bond to guarantee the 
eventual reimbursement of the compensations received by the participating companies, and retaining the power to suspend payments if such bond 
is not submitted.

Natural gas sales for electricity generation

On August 1, 2018, MINEM Resolution 46/2018 was published in  the Official Gazette, which instructed the Under-Secretariat of Electric Energy to 
take  the  necessary  measures  for  CAMMESA  to  implement  competitive  mechanisms  aimed  at  securing  the  availability  of  gas  for  the  production  of 
electric energy, and established new maximum prices (20% lower than the then current prices) for natural gas at the TSEP, for each basin of origin, to be 
applied in order to estimate the cost of the natural gas volumes to be used in the production of electricity to be marketed on the WEM , or, generally, to 
be used in the provision of the electric power public distribution service from August 1, 2018. 

On  November 7,  2018,  SGE  Resolution  No. 70/2018  was  published  in  the  Official  Gazette,  which  amended  Resolution  No. 95/2013  issued  by  the 
former Secretariat of Energy, authorized Generators, Co-Generators and Self-Generators of the WEM to contract the supply of their own fuel for the 
generation of electric energy. In addition, this Resolution establishes the costs of generation with their own fuel shall be appraised in accordance with 
the mechanism of recognizing the Variable Production Costs recognized by CAMMESA. 

30.h) Regulatory requirements applicable to Natural Gas distribution 

The Group participates in natural gas distribution through its subsidiary Metrogas. 

The natural gas distribution system is regulated by Law No. 24,076 (the “Gas Act”) that, together with Decree No. 1,738/1992, issued by the Executive 
Power, other regulatory decrees, the specific bidding rules (Pliego), the Transfer Agreement and the License, establishes the Regulatory Framework for 
Metrogas’ business. 

The License, the Transfer Agreement and the regulations issued pursuant to the Gas Act establish requirements regarding the quality of service, capital 
investment,  restrictions  on  transfer  and  encumbrance  on  assets,  cross-ownership  restrictions  among  producers,  transporters  and  distributors,  and 
Metrogas stock transfer.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2018, 2017 AND 2016

30. MAIN REGULATIONS AND OTHER (Cont.) 

The Gas Act and the License created ENARGAS as the regulatory entity to administer and enforce the Gas Act and the applicable regulations. In this 
order, the tariffs for the gas distribution service were established by the License and are regulated by ENARGAS. ENARGAS’ jurisdiction extends to 
gas transportation, sale, storage and distribution. Its mandate under the Gas Act includes consumer protection, competition protection in gas supply and 
demand, and the promotion of long-term investments in the gas industry. 

Gas distribution tariffs have been established in the License and are regulated by ENARGAS. 

•

Distribution License

The License authorizes Metrogas to provide the public distribution service for a term of 35 years. The Gas Law provides that Metrogas may request 
from  ENARGAS  a  License  renewal  for  an  addition  term  of  ten  years  upon  the  expiration  of  the  original  35  year-term.  The  ENARGAS  will  then 
evaluate  Metrogas’  performance  and  make  a  recommendation  to  the  Argentine  Executive  Branch.  Metrogas  is  entitled  to  the  renewal  of  its  License 
unless the ENARGAS proves that it has not substantially performed all of its obligations under the Gas Law, the respective regulations and decrees and 
the License. 

At the end of the 35 or 45-year period, as the case may be, the Gas Law requires a new competitive bidding to grant the license, for which, if it has 
performed its obligations, Metrogas will have the option to equal the best bid made to the Government by a third party. 

Generally, upon the termination of a License due to completion of its time-period, Metrogas will be entitled to a consideration equal to the value of the 
designated assets or to the amount paid by the successful bidder in a new call for tenders, whichever is lower. 

Metrogas has various obligations under the Gas Law, including the obligation to comply with all reasonable requests within its service area. A service 
request  will  not  be  deemed  reasonable  if  it  were  uneconomic  for  a  distribution  company  to  undertake  the  requested  service.  Metrogas  is  obliged  to 
operate and maintain its facilities in a safe manner, which may require certain investments to replace or upgrade its facilities pursuant to the License. 

The License specifies other obligations of Metrogas, including the obligation to provide a distribution service, to maintain continuous service, to operate 
the system in a prudent manner, to maintain the distribution network, to make the Mandatory Investments, to keep certain accounting records and to 
provide certain regular reports to the ENARGAS. 

The License may be revoked by the Argentine Government, upon recommendation from the ENARGAS, in the following cases: 

•

•

•

•

•

•

Serious and repeated failure by the Metrogas to meet its obligations. 

Total or partial interruption in the uninterruptible service for reasons attributable to Metrogas for a term exceeding the periods set forth in 
the License in one calendar year. 

Sale, disposition, transfer and encumbrance of Metrogas Core Assets, without the prior authorization of the ENARGAS, except where the 
said encumbrance is used to finance extensions and improvements to the gas pipeline system. 

Bankruptcy, dissolution or liquidation of Metrogas. The bankruptcy proceedings did not affect the normal course of Metrogas operations, 
and therefore, could not be the reason for the revocation of the Metrogas License. 

Ceasing  the  provision  of  the  services  provided  for  in  the  License,  or  the  attempt  to  unilaterally  assign  or  transfer,  in  whole  or  in  part 
(without the previous authorization of the ENARGAS), or the waiver of, other than as permitted. 

Transfer of the Technical Assistance Contract or the delegation of the duties specified in the Contract, without the previous authorization of 
the ENARGAS, during the first ten years from License granting. 

In relation to restrictions, the License provides that Metrogas will not assume its parent company’s debts or grant credits or encumber assets to secure 
debt of, or award any other benefit to, its parent company’s creditors.

Tariff renegotiation

The Emergency Law published in the Official Gazette on January 7, 2002 affected the legal framework for license contracts of public utility companies. 

The main provisions of the Emergency Law that affected the License granted to Metrogas by the Argentine Government are: The “pesification” of the 
tariffs  established  in  U.S.  dollars  convertible  at  the  exchange  rate  specified  in  the  Convertibility  Law  (Law  No. 23,928),  the  prohibition  of  tariff 
adjustment based on any foreign index, thereby preventing the application of the international index fixed in the Regulatory Framework (Producer Price 
Index -PPI- of the United States) and the renegotiation of the License granted to Metrogas in 1992. 

In  addition,  the  Emergency  Law  ordered  the  renegotiation  of  public  services  contracts  awarded  by  the  Argentine  Executive  Branch,  and  that  public 
utility companies were bound to continue performing all their duties. 

The Emergency Law, which originally expired in December 2003, was successively extended to December 31, 2017. The terms for license renegotiation 
and public services concessions were also progressively extended. 

Within  the  framework  of  the  renegotiation  process,  Metrogas  executed  a  number  of  agreements  with  the  various  entities  on  behalf  of  the  Argentine 
Government. 

The agreements entered into and in force as of December 31, 2018 are described below: 

i.

Transitional Agreement 

In  this  regard,  on  March 30,  2017,  Metrogas  executed  a  Transitional  Agreement  with  the  MINEM  and  the  Ministry  of  Finance  providing  for  the 
temporary adjustment of prices and tariffs for the Natural Gas Distribution Public Service, the specific impact of the amounts provided therein until the 
subscription of the Memorandum of Agreement for Comprehensive Contractual Renegotiation and the entry into force of the definitive tariff schemes 
resulting from the Comprehensive Tariff Review (the “CTR”). The 2017 Transitional Agreement is supplementary to the 2008 Transitional Agreement 
and amends the 2017 Transitional Agreement and the 2016 Transitional Agreement previously executed. 

The 2017 Transitional Agreement, which is not subject to ratification by the PEN establishes a transitional tariff regime as of April 1, 2017, consisting 
of the readjustment of tariffs based on the guidelines necessary to maintain the continuity of the service for the purpose of allowing Metrogas to meet its 
operating and maintenance, administration and marketing expenses, those expenses corresponding to the execution of the mandatory investment plan 
determined by the ENARGAS and to comply with the respective payment obligations, maintaining its chain of payments for the purpose of ensuring the 
continuity of the regular provision of the public service under their charge until the entry into force of the tariff regime resulting from the Memorandum 
of Agreement for a Contractual Renegotiation. 

Likewise,  the  2017  Transitional  Agreement  provides  for  the  transfer  of  the  impact  of  changes  in  tax  regulations  pending  resolution,  except  for  the 
income tax, and incorporates a Mandatory Investment Plan to which Metrogas is committed. 

Lastly,  Metrogas  will  not  be  authorized  to  distribute  dividends  without  previously  proving  to  ENARGAS  the  full  compliance  with  the  Mandatory 
Investment Plan. 

On March 30, 2017, the MINEM instructed the ENARGAS, through Resolution No. 74—E/2017, to put into effect the tariff schemes resulting from the 
CTR process. 

In this regard, it set forth that for the gradual and progressive implementation of this measure, the ENARGAS should apply on a progressive basis, the 
rate  increases  resulting  from  the  CTR  as  follows:  30%  of  the  increase,  from  April 1,  2017,  40%  of  the  increase,  as  of  December 1,  2017,  and  the 
remaining 30%, as of April 1, 2018.

30. MAIN REGULATIONS AND OTHER (Cont.) 

Moreover, and for cases in which the corresponding Comprehensive Contractual Renegotiation Memorandum of Agreement had not entered into force, 
it instructed the ENARGAS to apply to the Licensees (including Metrogas) a transitory tariff adjustment because of the CTR. 

On March 31, 2017, ENARGAS Resolution No. 4,356/2017 was published in the Official Gazette through which the tariff schemes resulting from the 
Metrogas  CTR,  effective  as  of  April 1,  2017  and  the  temporary  tariff  schemes  applicable  to  Metrogas  users  were  approved.  Through  differentiated 
tariffs, ENARGAS Resolution No. 4,356 / 2017 determined tariff schemes for residential users who recorded savings in their consumption equal to or 
greater  than  15%  with  respect  to  the  same  period  of  2015,  as  well  as  those  that  would  apply  to  the  beneficiaries  of  the  “Social  Tariff”  (Resolutions 
No. 28/2016 of the MINEM and ENARGAS No. I-2,905/2014 and No. 3,784/2016) and the Entidades de Bien Público (Public Welfare Entities) (Law 
No. 27,218). 

The tariff schemes corresponding to beneficiaries of the “Social Tariff” were rectified by ENARGAS Resolution No. 4,369 2017. The billing resulting 
from  the  application  of  the  new  transitory  tariff  shames  must  respect  the  limits  established  in  Article  10  of  MINEM  Resolution  No. 212/2016,  and 
therefore the criteria of ENARGAS Resolution No. I-4,044/2016 are maintained. 

Likewise, ENARGAS Resolution No. 4,356/2017 overruled ENARGAS Resolutions No. I-2,407/12 and No. I-3,249/15 that enabled the collection of a 
fixed amount per invoice under the operation of the Fund for Gas Distribution Consolidation and Expansion Works (“FOCEGAS”). 

In addition, ENARGAS Resolution No. 4,356/2017 approved: (i) the technical economic studies of the Company’s CTR, (ii) the non-automatic Semi-
Annual  Adjustment  Methodology  to  become  effective  jointly  with  the  License  Readjustment  Memorandum  of  Agreement  and  (iii) the  Metrogas 
Investment Plan for the next five-year term. 

On  October 24,  2017,  and  through  ENARGAS  Resolution  No. 74/2017,  a  public  hearing  was  called  for  November 15,  2017  in  order  to  consider  the 
transitory tariff adjustment effective as of December 1, 2017, corresponding to Metrogas. 

On  December 1,  2017,  the  Official  Gazette  published:  (i) ENARGAS  Resolution  No. 131/2017  that  ordered  (a) to  declare  the  validity  of  the  Public 
Hearing  called  by  ENARGAS  Resolution  No. 74/2017,  (b)  approve  Metrogas  temporary  tariff  scheme  applicable  as  of  December 1,  2017;  and 
(c) approve  new  values  for  the  Rates  and  Charges  received  by  Metrogas  for  Additional  Services;  and  (ii) ENARGAS  Resolution  N°  132/2017  that 
provides for a bonus to be implemented by Metrogas in favor of certain users who (a) record savings in their consumption; or (b) are beneficiaries of the 
Social Tariff. 

On  January 31,  2018,  ENARGAS  Resolution  No. 249/2018  was  published  in  the  Official  Gazette,  which  called  for  a  public  hearing  to  be  held  on 
February 22,  2018  to  consider  (i) the  application  of  the  Semi-Annual  Tariff  Adjustment  Methodology,  if  applicable,  for  the  adjustment  of  Metrogas 
tariffs; (ii) the application of the transfer to tariffs of the price of the purchased gas; and (iii) methodological alternatives for a more predictable billing of 
residential users’ consumption.

On  March 28,  2018,  ENARGAS  Resolution  No. 300/2018  was  published  in  the  Official  Gazette  declaring  the  Public  Hearing  No. 94  valid  and 
approving the final tariff schedules applicable as of April 1, 2018. 

On September 27,  2018, SGE Resolution No. 14/2018 applicable to distribution companies’ billing as of  October 1, 2018,  was published and among 
other factors: i) eliminated the billing limits and discounts established by MINEM Resolutions No. 212/2016 and No. 474/2017, and established a new 
discount of 100% for social tariff users for the base consumption block established in Annex II to MINEM Resolution No. 474/2017, and consumptions 
in  excess  of  such  block  will  be  paid  at  100%;  ii)  established  that  the  Trust  Fund  for  Subsidies  of  Residential  Gas  Consumption  (section  75  of  Law 
No. 25,565)  would  be  2.96%  over  the  price  of  gas  at  the  TSEP  per  cubic  meter  and  also  that  the  billing  should  be  made  in  accordance  with  the 
procedures to be established by the ENARGAS. 

On October 8, 2018, FC ENARGAS Resolution No. 281/2018 was published in the Official Gazette declaring the validity of Public Hearing No. 96 and 
approving Metrogas Tariff Schedules, effective from its publication date for the summer period 2018-2019. Subsequently, FC ENARGAS Resolution 
No. 292/2018  issued  on  the  Official  Gazette  on  October 12,  2018,  rectified  the  tariff  schedules  of  the  aforementioned  FC  ENARGAS  Resolution 
No. 281/2018, with retroactive  application as of  October 8, 2018.  ENARGAS Resolution No. 292/2018  published on October 12,  2018, modified the 
Tariff Schemes and the Schedule of Rates and Charges for the additional services provided by Metrogas.

ii. Memorandum of Understanding for the Natural Gas Distribution License Contract (also known as “Memorandum of Understanding for the 

Comprehensive Contractual Renegotiation”) 

On  March 30,  2017,  and  within  the  framework  of  the  renegotiation  process  of  the  public  service  contracts  established  by  the  Emergency  Law,  its 
extensions  and  Decrees  No. 367/2016  and  N°  2/2017,  Metrogas  subscribed  with  the  MINEM  and  with  the  Ministry  of  Finance,  a  Memorandum  of 
Agreement for the Adaptation of the Natural Gas Distribution License Agreement (which contains the terms of the comprehensive renegotiation and 
conditions  for  the  adjustment  of  the  License  Agreement.  The  Memorandum  of  Agreement  is  based  on  the  2008  Transitional  Agreement,  the  2014 
Transitional Agreement, the 2016 Transitional Agreement and the 2017 Transitional Agreement. 

The  provisions  contained  in  the  Memorandum  of  Agreement,  once  it  has  entered  into  full  force  and  effect  after  being  ratified  by  the  PEN,  will  be 
applied during the contractual period ranging from January 6, 2002 and the termination of the License Agreement. 

A series of guidelines to be contemplated by the CTR process are established in the terms provided for therein. 

The Metrogas tariff scheme resulting from the Integral Tariff Review according to the indicated guidelines will be applicable once all the procedures 
provided  for  the  entry  into  force  of  the  Memorandum  of  Agreement  has  been  fulfilled.  The  CTR  will  become  in  full  force  and  effect  not  later  than 
December 31,  2017.  In  the  event  that  ENARGAS  provides  for  the  phased  and  progressive  application  of  the  tariff  increase  resulting  from  the 
Comprehensive Tariff Review, the application of the last step may not exceed April 1, 2018. 

As a condition prior to ratification, the Memorandum of Agreement for the Comprehensive Contractual Renegotiation provides for the suspension and 
withdrawal of all claims, appeals and complaints filed, pending or in the process of being executed, whether administrative, arbitral or judicial, in the 
Argentine  Republic  or  abroad,  which  are  founded  or  linked  to  the  facts  or  provided  measures,  with  respect  to  the  License  Agreement,  as  of  the 
Emergency  Law  and/or  in  the  annulment  of  the  PPI  Index  (Producer  Price  Index  of  the  United  States  of  America).  Moreover,  the  Memorandum  of 
Agreement must be ratified by the Shareholders’ Meeting of Metrogas, so that the PEN issues the Decree ratifying the terms of the Memorandum of 
Agreement. On April 27, 2017, the Shareholders’ Meeting of Metrogas ratified the Memorandum of Agreement for the Adaptation of the Natural Gas 
Distribution License Agreement. 

Finally, the Memorandum of Agreement provides for the Company’s commitment to make, during the effective term of the License, plus its potential 
ten-year extension and within the area of its License, additional sustainable investments equivalent to the amount of the award rendered in the arbitration 
proceedings  in  re:  “BG  Group  Plc.  vs.  The  Argentine  Republic  (UNC  54  KGA)”  with  the  proportional  abatement  percentage  that  would  have  been 
established in the payment agreement and excluding the amounts corresponding to the default interest on the payment of the award. The amount and the 
plan for additional investments will be determined by ENARGAS at the proposal of the Company and they will not be included in the rate base. 

With  respect  to  those  Licensees  whose  Memorandum  of  Agreement  had  not  entered  into  force,  the  ENARGAS  was  instructed  to  apply  to  them  a 
temporary adjustment of tariffs on account of the CTR, taking into consideration, to such effects, the studies carried out under such CTR in compliance 
with the provisions set forth in Article 1 of MINEM Resolution No. 31/2016. 

On March 28, 2018, Decree No 252/2018 was published in the Official Gazette whereby the PEN ratifies the Memorandum of Agreement entered into 
by MINEM, the Ministry of Economy and Metrogas. 

iii.

Temporary economic assistance 

MINEM  Resolution  No.  312  -  E/2016  was  published  in  the  Official  Gazette,  on  December 30,  2016,  which  ordered  a  new  temporary  economic 
assistance to the Licensees of the Natural Gas Distribution Service through Networks for the period April-September 2016, for the purpose of funding 
the mandatory investments established (with respect to Metrogas) in ENARGAS Resolutions No. 3,726/2016 and No. 4,044/2016, and the payment to 
gas producers; all of which is on account of the CTR. 

Under  the  terms  of  the  Resolution,  the  transfer  of  the  amounts  assigned  to  Metrogas  of  759  was  applicable  as  long  as,  at  the  discretion  of  the 
ENARGAS, the financial situation of Metrogas that gave rise to the assistance was maintained taking into account the availability of funds to meet its 
investment obligations and payments to gas producers.

30. MAIN REGULATIONS AND OTHER (Cont.) 

For the release of the funds corresponding to the temporary financial assistance, Metrogas had to file a sworn statement with the ENARGAS, in the 
terms of ENARGAS Note No. 106/2017, on the allocation to be given to the amounts required. In accordance with the ENARGAS criteria, if the sworn 
statements meet the requirements  of MINEM  Resolution  No.  312 -  E/2016, they  would  be  sent  to the MINEM Hydrocarbons  Secretariat  in  order  to 
arrange  for  the  transfer  of  the  assistance.  Likewise,  the  Resolution  set  forth  that  the  Licensees  could  not  distribute  dividends  under  the  terms  of 
Resolution No. 31/2016 of the MINEM. 

On March 31, 2017, Metrogas received the amount of 759 corresponding to MINEM Resolution No. 312 - E/2016. 

iv. New gas prices at the TSEP and Metrogas transition tariff schemes 

Through Resolution No. 74 - E/2017, the MINEM determined the new natural gas prices at the TSEP applicable from April 1, 2017 to the categories of 
users indicated therein. Moreover, it determined the new prices at the TSEP, subsidized for natural gas Residential users who register a saving in their 
consumption equal or superior to fifteen percent (15%) with respect to the same period in 2015. These new prices in the TSEP have been contemplated 
in ENARGAS Resolution No. 4.356/2017. 

MINEM Resolution No. 474-E/2017 determined the new Gas prices at the TSEP as of December 1, 2017. In addition, a 10% discount is established on 
the Gas price for all categories of Residential users who register a saving in their consumption equal to or greater than 20% with respect to the same 
period in 2015, and it establishes that the bonus corresponding to the Social Tariff beneficiaries will be equivalent to: i) 100% of the Natural Gas price 
on the consumption block base determined by Resolution; and ii) 75% of the price of Natural Gas on a surplus consumption block of equal volume to 
that determined in paragraph i). Consumptions over  and above the block indicated in paragraph ii) will be paid by 100%. It also establishes that the 
billing resulting from the application of the new tariff schedules must respect the limits established in Article 10 of Resolution No. 212 dated October 6, 
2016 of the MINEM. These new prices in the TSEP have been contemplated in the ENARGAS Resolution No. 131/2017, which approved the Metrogas 
temporary tariff scheme, applicable as of December 1, 2017. 

v.

Procedure for the compensation of the lower revenues that the Distributors receive from their users for benefits and / or bonuses and for higher 
costs of unaccounted gas 

MINEM Resolution No. 508-E/2017, published on December 29, 2017, established the procedure for the compensation of the lower revenues that the 
Licensees  of  the  Natural  Gas  Distribution  Service  through  Networks  receive  from  their  users,  as  a  product  of:  (i) the  application  of  benefits  and/or 
discounts to users arising from the regulations in force in the tariff area of the distribution service of natural gas through networks, and (ii) the higher 
UNG costs compared to those established for its recognition in the rates, applicable as of January 1, 2018. 

vi. Winter consumption financing program 

On March 27, 2018, a memorandum of intent was signed with ENARGAS, natural gas producers, distribution and transportation companies in order to 
commit efforts aimed at the development of a natural gas winter consumption financing program jointly with the subscribing parties. 

On  June 12,  2018,  ENARGAS  Resolution  No  97/2018  was  published  in  the  Official  Gazette,  which  set  forth  the  Natural  Gas  Winter  Consumption 
Financing Program (the “Program”). Adherence to the Program by beneficiary users was optional and voluntary. In accordance with the terms of the 
Program, the residential and commercial consumers of natural gas full service could hereunder finance payment of 25% of the invoices issued between 
July 1  and  October 31,  2018.  The  interest  rate  applicable  to  this  option  was  the  BNA  deposit  rate  for  electronic  means  for  the non-financial  private 
sector for 30-day deposits for the month prior to the one being invoiced. Accrued financing and interest thereon would be recovered through the regular 
invoices  issued  after  November 1,  2018,  and  for  three  succeeding  consecutive  periods  for  bimonthly  customers  and  for  six  consecutive  periods  for 
monthly customers. Financing involved each of the activity segments (gas, transport and distribution), and it was exceptional for the winter of 2018.

vii. Amendment to Basic Rules for the Distribution License 

On March 28, 2018, MINEM Resolution No. 91/2018 was published in the Official Gazette. Such resolution unifies the terms for the adjustment due to 
variations in prices of the purchased gas or seasonal adjustment and the six-month adjustment of tariffs, providing that once the transition period has

following year. 

viii. Reduction for social tariff users 

On  May 23,  2018,  MINEM  Resolution  218/2018  was  published  in  the  Official  Gazette  (later  instrumented  by  ENARGAS  by  means  of  Resolution 
No. 86/2018)  which  provides  for  suspension  of  the  reduction  criteria  application  for  social  tariff  users  set  forth  in  Resolution  No. 474/2017  for 
consumptions  made  in  May  and  June  2018.  For  invoicing  such  consumption,  the  social  tariff  regime  within  the  scope  provided  for  in  MINEM 
Resolution No. 28/2016 shall be applicable, to which end the 100% reduction of the natural gas price these users consume should be considered.

Note of ENARGAS relating to the equity interest of YPF in Metrogas

The Company has received from Metrogas a copy of the note received by it from ENARGAS, requesting it to adjust Metrogas’ equity structure in line 
with the term provided for in Emergency Law No. 25,561 and in compliance with Section 34 of Law 24,076. In this regard, it should be noted that YPF 
indirectly acquired 70% of Metrogas equity, transaction that was approved by ENARGAS Resolution No. I/2,566 dated April 19, 2013; and, following 
the merger with YPF Inversora Energética S.A. and Gas Argentino S.A., is the holder of 70% of Metrogas shares. 

On March 30, 2017, YPF filed an appeal for reconsideration requesting to overrule the ENARGAS Note and render a new decision setting a reasonable 
timeframe consistent with the current reality of the gas market to comply with the provisions set forth article 34 of Law 24,076. 

On June 15, 2017, YPF submitted to ENARGAS a tentative schedule for the process of adapting its equity interests in Metrogas, which was expanded in 
detail on July 3, 2017. Such presentation does not imply withdrawal of the aforementioned appeal. 

On  April 5,  2018,  ENARGAS  rejected  the  reconsideration  petition  filed  by  YPF  on  March 30,  2017.  ENARGAS  decision  was  notified  to  YPF  on 
April 6, 2018 by means of ENARGAS Resolution No. 313/2018. 

YPF requested examination of the proceedings, which was granted by ENARGAS on September 10, 2018, which in turn enabled the company to file an 
appeal in time. 

On October 8, 2018, YPF filed an appeal for resolution by the SGE. As of the date of issuance of these consolidated financial statements, this appeal is 
pending resolution.

Note from the ENARGAS on deferred collection to residential users

On  August 25,  2017,  the  ENARGAS  issued  some  Notes  instructing  the  Licensees  of  the  Gas  Distribution  Service  (“Distributors”),  by  virtue  of  the 
presentation received from the MINEM, and in relation to the invoices to be issued from August 25, 2017 and until October 31, 2017 for residential 
users,  to  contemplate  a  fifty  percent  (50%)  payment  deferral  of  the  total  amount  of  the  settlement  corresponding  to  the  billing  period,  without  any 
interest. According to this instruction, the amounts subject to deferral must be included in the first invoice issued after October 31, 2017 in accordance 
with the guidelines related to the issuance of Public Service Settlement receipts for bimonthly invoicing with monthly payment obligations currently in 
force, i.e., in two equal and consecutive monthly installments. Such deferral is  not applicable to residential users  who are beneficiaries of the Social 
Tariff. 

The Notes sent by the ENARGAS also contemplate that, if there is a financial impact on the Distributors’ income by virtue of such deferral, such impact 
will be timely evaluated and assumed by the Argentine Government through the corresponding budgetary management.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2018, 2017 AND 2016

30. MAIN REGULATIONS AND OTHER (Cont.) 

On September 20, 2017, YPF submitted a note to the MINEM (with a copy to ENARGAS), requesting the intervention of the MINEM so that it adopts 
the necessary measures to prevent the instruction given by the ENARGAS from being misinterpreted by some Distributors to place on the Producers, 
such as YPF, the financial impact that such a measure could cause, through the unilateral postponement of the payment obligations by the Distributors. 
As of the date hereof, the note submitted by YPF is yet to be answered. 

As a result of the changes introduced through MINEM Resolution No. 474—E/2017 and ENARGAS Resolutions No. 131/2017 and No. 132/2017, and 
the guidelines established in the Terms and Conditions MINEM, Resolution No. 508-E / 2017 was published on December 29, 2017, which establishes 
the procedure for the compensation of the lower revenues that the Licensees of the Natural Gas Distribution Service through Networks receive from 
their users, as a result of: (i) the application of benefits and / or discounts to users resulting from the regulations in force regarding the tariffs applicable 
to the natural gas distribution service through networks; and (ii) the higher costs of the UNG with respect to those established for its recognition in the 
tariffs. 

In  accordance  with  the  compensation  procedure,  the  Distribution  Licensees  must  inform  to  the  ENARGAS  within  the  terms  established  therein  and 
based on the annualized monthly consumption and as a sworn statement, the amounts required to compensate the aforementioned differences. The same 
information regime is adopted in relation to UNG. 

Thus,  in  order  to  calculate  compensations  for  the  amount  that  they  do  not  receive  for  the  discounts  in  billing  as  well  as  for  the  UNG  differences, 
compensation is established resulting from the difference between the purchase price to the natural gas producer and the sale to its customers.

Benchmark prices for the butane commercialization chain

On April 5, 2017, the Secretariat of Hydrocarbon Resources published Resolution No. 56-E/2017 in the Official Gazette, establishing new maximum 
benchmark  prices  for  the  different  segments  of  the  butane  commercialization  chain  to  be  bottled  in  10,  12  and  15  kg  bottles  under  the  Household 
Program  (Decree  No. 470/2015  and  former  Energy  Secretariat  Resolution  No. 49/2015),  and  modifying  the  benchmark  prices  established  in  former 
Energy Secretariat Resolution No. 70/2015. The new maximum benchmark prices for the Company are Ps. 2,568/TN for butane and Ps. 2,410/TN for 
propane. For fractionators such as YPF GAS S.A., the prices established by Resolution No. 56-E/2017 are Ps. 63.89 for 10 kg bottles, Ps. 76.67 for 12 
kg bottles and Ps. 95.84 for 15 kg bottles. 

On June 7, 2017, the Secretariat of Hydrocarbon Resources published Resolution No. 75/2017 in the Official Gazette, which modifies the regulations 
applicable  to  the  Household  Program  (former  Energy  Secretariat  Resolution  No. 49/2015)  and  provides  that  the  adjustment  of  benchmark  prices 
applicable to the different segments of the butane commercialization chain to be bottled in 10 and 12 kg bottles will not be implemented automatically 
in quarterly periods. Instead, those adjustments will be made at the discretion of the Secretariat of Hydrocarbon Resources in its capacity as enforcement 
authority of the Household Program. In addition, the resolution establishes that the adjustment of benchmark prices for LPG producers and fractionators 
on account of the Comprehensive Tariff Review established by the Household Program in its regulations will take place only after the prior analysis of 
cost variations and their incidence, and taking into account regional, distribution and logistical factors. 

MINEM Resolution No. 287-E/2017, published on December 1, 2017, established new maximum benchmark prices and compensations for butane and 
propane  producers  effective  from  December 1,  2017,  and  introduced  amendments  to  the  Annex  to  the  Regulation  of  the  Bottle-to-Bottle  Program 
approved by Resolution No. 49/2015, among which, it is prohibited to charge the distributors for any additional service whatever its denomination, if in 
doing so the maximum benchmark prices and the maximum allowed deviations are exceeded. 

Regulation  No. 5  of  the  Undersecretariat  of  Hydrocarbon  Resources  was  published  on  March 28,  2018,  which  established  new  maximum  reference 
prices for the commercialization of butane for the sale of bottled LPG, effective as of April 1, 2018.

Tax Reform

Laws  No. 27,430  and  27,432  were  published  in  the  Official  Gazette  on  December 29,  2017,  and  significantly  modified  several  taxes.  The  main 
modifications are the following: 

•

Income tax 

•

Corporate tax rate and withholdings on dividends 

The  general  income  tax  rate  applicable  to  limited  companies  (sociedades  de  capital)  is  reduced  from  the  current  35%  to  30%  for  fiscal  years 
beginning January 1, 2018 and ending December 31, 2019 inclusive, and to 25% for those fiscal years beginning January 1, 2020 onwards. 

Moreover, a new withholding on dividends is established, which will be 7% for those fiscal years beginning on January 1, 2018 and ending on 
December 31, 2019, and 13% for those fiscal years beginning on or after January 1, 2020 onwards. 

Finally, the tax equalization (a 35% withholding is applicable when dividends exceed the amount of the taxable income) is no longer applied on 
the income accrued as of January 1, 2018. 

•

Capital gains for foreign beneficiaries 

The new law establishes a 15% withholding on capital gains derived from the sale of shares or other similar securities (calculated on the actual or 
presumed gains equivalent to 90% of the sale price). The law establishes an exemption applicable to foreign beneficiaries who sell listed shares 
under the supervision of the CNV. Furthermore, an exemption is established for the interest and sale results of government bonds, NO and ADRs. 
These  exemptions  will  only  apply  to  non-resident  foreign  beneficiaries  whose  funds  do  not  derive  from  non-cooperating  jurisdictions.  Finally, 
such exemption does not apply to those benefits derived from the securities known as Lebacs. 

In the case of ADRs, the law defines that the source thereof is given by the residence of the issuer of the respective shares. 

•

Indirect transfers made by the Foreign Beneficiaries 

The law establishes a tax on the indirect sale of assets located in Argentina. In particular, such tax will be levied on sales or transfers made by 
foreigners who own a company also abroad who owns assets in the country, when such assets are significant, i.e., when the following conditions 
are met: (i) at least 30% of the value of the shares in the foreign company derives from assets located in Argentina; and (ii) the transferred shares 
represent at least 10% of the assets of the foreign company. 

The  applicable  rate  will  be  15%  (calculated  on  real  net  profit  or  presumed  net  profit  equivalent  to  90%  of  the  sale  price)  in  the  proportion 
corresponding to Argentine assets. It is applicable to indirect transfers over assets acquired as from January 1, 2018. 

•

Costs for the abandonment of hydrocarbon wells 

The deduction of well abandonment expenses is admitted as they are considered as an integral part of the computable cost of the investments in 
wells,  those  costs  intended  to  satisfy  the  technical  and  environmental  requirements  by  the  concessionaire  and/or  permit  holder  required  by  the 
enforcement authority. They will be included from the date on which such obligations arise in accordance with current regulations, regardless of 
the period in which the effective disbursement is made.

•

Other modifications 

It replaces the tax transparency rules contemplating broader situations and introduces the presumed dividend concept. 

Moreover, it ratifies the taxability of the sales of shares of Argentine companies made by non-residents as of the effectiveness of Law 26,983, 
although it establishes the taxation of results in the cases of sales made through stock exchanges or similar markets, when the stockbroker did not 
withhold the tax. 

•

Tax revaluation of assets 

The regulation establishes that, at the option of the companies, tax revaluation of assets is permitted for assets located in Argentina and affected to 
the generation of taxable profits. The special tax on the amount of the revaluation depends on the asset, being 8% for real estate not classified as 
inventories, 15% for real estate classified as inventories, 5% for shares, quotas and equity interests owned by individuals and 10% for the rest of 
the assets. As of the date of approval by the Board of Directors of these consolidated financial statements, the Group was analyzing the possibility 
of  exercising  the  option.  The  gain  generated  by  the  revaluation  is  exempted  according  to  article  291  of  Law  27,430  and,  the  additional  tax 
generated by the revaluation is not deductible. For information relating subsequent events after the approval by the Board of Directors of these 
consolidated financial statements, see Note 34. 

•

Tax on Fuels 

The main modifications are the following: 

•

•

A new tax is introduced: tax on carbon dioxide, which added to the tax on fuels as of the date of publication of the rule provided a similar 
tax burden as the previous one. 

Both  taxes  are  levied  based  on  a  fixed  amount  per  liter  adjusted  for  CPI  on  a  quarterly  basis.  In  the  case  of  carbon  dioxide,  two  new 
products are incorporated: petroleum coke and mineral coal. 

•

Tax on bank debit and credits 

The PEN may fix the tax percentage to be computed as payment on account of the income tax, which will be progressively increased by up to 
20% per year as of January 1, 2018, and it may also establish that this tax will be fully computed as payment on account of the income tax in 
2022. 

On May 7, 2018, by means of Decree No. 409/2018, the PEN provided that 33% of the amounts debited from the tax may be computed both for 
account credits and debits. 

•

Value added tax 

A system of refund of tax paid for investments in fixed assets is established, subject to the future generation of tax debits, in order to reduce the 
financial cost generated by the accumulation of tax credits of new investments. 

•

Social Security 

There will be a minimum monthly salary exempt from employer contributions, while the rate of the same will be unified around 19.5%, although 
VAT tax credits will be eliminated for employment in secondary areas. These changes will occur by 2022, gradually converging from the current 
situation. 

•

Payment Plan

On March 1, 2019, AFIP’s Resolution No. 4434/2019, was published in the Official Gazette, establishing a payment facility plan for tax liabilities being 
heard at the Fiscal Tribunal of the Nation (Tribunal Fiscal de la Nación). This financing plan, which may be submitted until June 30, 2019, establishes a 
variable rate with payment terms of up to 5 years. In order to adhere to this regime, the taxpayer shall previously waive any action or right, including the 
right of recourse, in relation to the obligation to be repaid under the payment plan.

SUBSEQUENT EVENTS 

•

•

•

Resolution No. 1/219 of the Secretariat of Renewable Resources and Electricity Market was published on March 1, 2019, which, effective as from 
March 1, 2019, abrogated Resolution No. 19/2017 issued by the former Secretariat of Electric Energy and, among other aspects, established new 
compensation  schemes  for  guaranteed  power  availability  and  generation  of  Generators,  Co-Generators  and  Self-Generators  of  the  WEM 
(exempting  from  this  regime  the  generation  of  Bi-national  Hydroelectric  Power  Plants  and  Nuclear  Generation,  as  well  as  Generators,  Co-
Generators and Self-Generators of the WEM with generating units with power committed within the framework of centralized contracts aimed at 
the Supply of the WEM demand). The power charges for the six months of lowest electric demand and for generation approved by Resolution No. 
1/2019 are about 20% lower in U.S. dollars than those provided under Resolution No. 19/2017. 

In  connection  with  Fernández  Oro  Concession,  the  Secretariat  of  Energy  issued  resolutions  authorizing  the  payment  to  YPF  of  Definitive 
Compensations  for  the  first  quarter  of  2018  and  Provisional  Compensations  for  the  third  quarter  of  2018,  whose  amounts  were  determined 
considering  as  a  limit  the  estimation  of  the  Included  Production  YPF  initially  reported.  Recently,  YPF  has  administratively  challenged  these 
resolutions, understanding that the amount of the Compensations must be determined on the basis of the production actually produced each month 
in the Concession, without applying any limit. 

On  March  21,  2019,  the  Company’s  management  informed  the  Board  of  Directors  of  the  decision  to  adhere  to  the  tax  revaluation  and  to  the 
payment plan for lawsuits maintained within the Argentine Tax Court as mentioned in Note 30.j. The quantified effects, as of January 1, 2019, are 
detailed below. 

With respect to the tax revaluation, which expired on March 29, 2019 and to which the Company adhered, in relation to the category of “Mines, 
quarries, forests and similar goods”, the regulation establishes the payment of a special tax of 10%, which implies a loss of approximately 4,600 
and  will  allow  a  greater  deduction  of  the  depreciation  of  the  revalued  assets  on  income  tax  (including  its  annual  revaluation  for  tax  deduction 
purposes)  from  2018  fiscal  period  inclusive,  and  which  it  also  implies  the  recognition  of  a  gain  of  approximately  32,700  as  a  result  of  the 
recognition of the effect of such revaluation on deferred tax. 

Additionally,  in  relation  to  the  dispute  with  AFIP  over  the  cost  deduction  for  wells  abandonment  on  income  tax  (see  also  Note  28.b.4),  the 
Company  has  decided  to  adhere  to  the  payment  plan  for  the  years  2005-2010,  for  an  amount  of  approximately  5,500,  to  be  paid  on  60 
installments,  plus  a  variable  interest.  The  loss  due  to  the  recording  of  the  liabilities  for  all  the  years  not  prescribed  (including  the  previous 
mentioned amount) would amount to approximately 18,800. 

The effects resulting from these recently adopted decisions will impact the Company’s financial statements for the first quarter of the year 2019. 

As  of  the  date  of  issuance  of  these  consolidated  financial  statements,  there  are  no  other  significant  subsequent  events  that  require  adjustments  or 
disclosure in the financial statements of the Group as of December 31, 2018, or their description in a note to these consolidated financial statements, 
which were not already considered in such consolidated financial statements according to IFRS. 

The consolidated financial statements as of December 31, 2018, presented for regulatory purposes before the CNV, have been approved by the Board of 
Director’s  meeting  and  authorized  to  be  issued  on  March 7,  2019,  and  will  be  considered  in  the  shareholders’  meeting.  These  consolidated  financial 
statements, which comprise those presented before the CNV on March 7, 2019, an update of Note 34 – “Subsequent events” and the inclusion of Note 
35 – “Supplemental information on oil and gas producing activities (unaudited)”, have been approved by Management on April 3, 2019.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2018, 2017 AND 2016

SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED) 

The following information is presented in accordance with ASC No. 932 “Extractive Activities – Oil and Gas”, as amended by ASU 2010 – 03 “Oil and 
Gas Reserves. Estimation and Disclosures”, issued by FASB in January 2010. 

Oil and gas reserves 

Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable 
certainty to be economically producible (from a given date forward, from known reservoirs, and under existing economic conditions, operating methods 
and  government  regulations)  prior  to  the  time  at  which  contracts  providing  the  right  to  operate  expire,  unless  evidence  indicates  that  renewal  is 
reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must 
have  commenced  or  the  operator  must  be  reasonably  certain  that  it  will  commence  the  project  within  reasonable  time.  In  some  cases,  substantial 
investments in new wells and related facilities may be required to recover proved reserves. 

Information on net proved reserves as of December 31, 2018, 2017 and 2016 was calculated in accordance with the SEC rules and Financial Accounting 
Standards  Board  (“FASB”)  Accounting  Standards  Codification  (“ASC”)  932,  as  amended.  Accordingly,  crude  oil  prices  used  to  determine  reserves 
were  calculated  each  month  for  crude  oils  of  different  quality  produced  by  the  Company.  Consequently,  to  calculate  our  net  proved  reserves  as  of 
December 31, 2018, the Company considered the realized prices for crude oil in the domestic market taking into account the effect of export taxes as in 
effect as of each of the corresponding years (until 2020, in accordance with Decree No. 793/2018). For the  years beyond the mentioned periods, the 
Company considered the unweighted average price of the first-day-of-the-month for each month within the twelve-month period ended December 31, 
2018, which refers to the Brent prices adjusted by each different quality produced by the Company. 

Additionally, since there are no benchmark market natural gas prices available in Argentina, the Company considered the realized prices in the domestic 
market according to the SEC and FASB’Ss ASC 932 rules, but also taking into account the effect of certain market regulations set forth mainly during 
the second half of the year for certain natural gas segments. 

Notwithstanding the foregoing, commodity prices have changed significantly since 2016. See “Item 3. Key Information—Risk Factors—Risks Relating 
to  the  Argentine  Oil  and  Gas  Business  and  Our  Business—Our  oil  and  natural  gas  reserves  are  estimates”  and  “Item  3.  Key  Information—Risk 
Factors—Risks Relating to the Argentine Oil and Gas Business and Our Business—Our reserves and production are likely to decline”. 

Net  reserves  are  defined  as  that  portion  of  the  gross  reserves  attributable  to  the  interest  of  YPF  after  deducting  interests  owned  by  third  parties.  In 
determining net reserves, the Group excludes from its reported reserves royalties due to others, whether payable in cash or in kind, where the royalty 
owner has a direct interest in the underlying production and is able to make lifting and sales arrangements independently. By contrast, to the extent that 
royalty payments required to be made to a third party, whether payable in cash or in kind, are a financial obligation, or are substantially equivalent to a 
production  or  severance  tax,  the  related  reserves  are  not  excluded  from  the  reported  reserves  despite  the  fact  that  such  payments  are  referred  to  as 
“royalties” under local rules. The same methodology is followed in reporting our production amounts. 

Gas  reserves  exclude  the  gaseous equivalent  of  liquids  expected  to  be  removed  from  the  gas  on  concessions  and  leases,  at  field  facilities  and  at  gas 
processing plants. These liquids are included in net proved reserves of natural gas liquids. 

Technology used in establishing proved reserves additions in 2018 

YPF’s estimated proved reserves are based on estimates generated through the integration of available and appropriate data, utilizing well-established 
technologies  that  have  been  demonstrated  in  the  field  to  yield  repeatable  and  consistent  results.  Data  used  in  these  integrated  assessments  include 
information obtained directly from the subsurface via wellbore, such as well logs, reservoir core samples, fluid samples, static and dynamic pressure 
information, production test data, and surveillance and performance information. The data utilized also include subsurface information obtained through 
indirect measurements, including high quality 2-D and 3-D-seismic data, calibrated with available well control. Where applicable, geological outcrops 
information was also utilized. The tools used to interpret and integrate all these data included both proprietary and commercial software for reservoir 
modeling,  simulation  and  data  analysis.  In  some  circumstances,  where  appropriate  analog  reservoir  models  are  available,  reservoir  parameters  from 
these analog models were used to increase the reliability of our reserves estimates.

SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED) (Cont.) 

The paragraphs below explain in further detail the most significant changes in our proved reserves during 2018, 2017 and 2016. 

Changes in our estimated proved reserves during 2018 

Extensions and Discoveries 

As a result of wells drilled in unproved reserves and resources areas approximately 25 mmboe of proved developed reserves (8 mmbbl of crude oil, 1 
mmbbl of NGL and 92 bcf of natural gas), and 149 mmboe of proved undeveloped reserves (95 mmbbl of crude oil, 12 mmbbl of NGL and 238 bcf of 
natural gas) were added mainly due to new shale oil and gas projects from Loma La Lata Norte, Loma Campana, Bandurria Sur and La Amarga Chica 
fields. 

Main  proved  undeveloped  reserves  additions  are  related  to  Unconventional  and  Tight  Gas  activities  in  the  Neuquina  basin,  while  proved  developed 
reserves contributions come in most cases from the Neuquina, Noroeste and San Jorge basin projects. 

Improved Recovery 

A total of approximately 15 mmboe of proved reserves were added mainly due to new projects and positive production response. Main contributions 
come from Golfo San Jorge basin addition was 4.4 mmboe of proved developed and 8 mmboe of proved undeveloped secondary recovery reserves and 
3 mmboe from Neuquina basin. 

Sales and Acquisitions 

As  a  net  result  of  Sales  and  Acquisitions,  1.4  mmboe  of  proved  developed  reserves  were  reduced.  These  reserves  decrease  is  related  mainly  to  the 
change in participation for Cerro Bandera and Bandurria Sur fields and acquisition of participation in Llancanelo field. 

Revisions of Previous Estimates 

During 2018, the Company’s proved reserves were revised upwards by 156 mmboe (126 mmbbl of crude oil and 178 bcf of natural gas and a decrease 
of 1 mmbbl of NGL). 

The main revisions to proved reserves have been due to the following: 

• As a result of 2018 higher average oil and gas prices and lower operating costs, its impact on incomes, and on fields economic limit, 143 mmboe of 
Proved  Developed Reserves  were added. Changes occured mainly in fields of Neuquina  Basin  (56 mmboe),  Golfo San Jorge  basin (40  mmboe) and 
Austral Basin (31 mmboe). 

• New economic scenario also improved scheduled projects economics, resulting in a 48 mmboe Proved Undeveloped Reserves incorporation mainly 
from oil fields of Golfo San Jorge Basin (33 mmboe) and Neuquina basin (15 mmboe). 

• Total liquids and gas production performance from existing wells was better than expected, resulting in an addition of approximately 33 mmboe to 
proved developed reserves, according to new reserves estimates, mainly in the Neuquina and Golfo San Jorge basins. 

• Change of development strategy in certain areas which resulted in a downwards revision of 43 mmboe from previous projects mainly from Neuquina, 
Austral, and Golfo San Jorge basins. 

•  Same  primary  and  improved  recovery  oil  projects  development  schedules  were  modified  or  canceled,  resulting  in  5  mmboe  proved  undeveloped 
reserves reduction, mainly in Austral, Golfo San Jorge and Cuyana basins. 

• Changes in gas compression projects which resulted in a 5 mmboe reduction of proved undeveloped reserves, mainly from Neuquina basin 

• Net production results and forecasts from existing and new wells were lower than expected, resulting in a 13 mmboe reduction of proved reserves. 
Main differences were found in Nequina basin.

SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED) (Cont.) 

Changes in our estimated proved reserves during 2017 

Extensions and Discoveries 

As a result of wells drilled in unproved reserves and resources areas approximately 26 mmboe of proved developed reserves (7,4 mmbbl of crude oil, 
1,9 mmbbl of NGL and 94 bcf of natural gas), and 54 mmboe of proved undeveloped reserves (11,7 mmbbl of crude oil, 3,4 mmbbl of NGL and 219 bcf 
of natural gas) were added. 

Main  proved  undeveloped  reserves  additions  are  related  to  Unconventional  and  Tight  Gas  activities  in  the  Neuquina  basin,  while  proved  developed 
reserves contributions come in most cases from the Neuquina and San Jorge basin projects.     

Improved Recovery 

A total of approximately 32 mmboe of proved reserves were added mainly due to new projects and positive production response. Main contributions 
come from Neuquina basin (5,4 mmboe of proved developed and 10 mmboe of proved undeveloped reserves) while Golfo San Jorge basin addition was 
5,6 mmboe of proved developed and 9,6 mmboe of proved undeveloped secondary recovery reserves. 

Sales and Acquisitions 

As  a  net  result  of  Sales  and  Acquisitions,  2.3  mmboe  of  proved  developed  reserves  were  added.  These  reserves  increase  is  related  to  the  change  in 
participation for Aguada de la Arena field. 

Revisions of Previous Estimates 

During 2017, the Company’s proved reserves were revised downwards by 96 mmboe (71 mmbbl of crude oil and 161 bcf of natural gas and an increase 
of 4 mmbbl of NGL). 

The main revisions to proved reserves have been due to the following: 

• As a result of 2017 lower average oil and gas prices and higher operating costs, its impact on incomes, and on fields economic limit, 105 mmboe of 
Proved Developed Reserves were deducted. Changes occured mainly in fields of Neuquina basin (-60 mmboe, Golfo San Jorge Basin (-25 mmboe) and 
Cuyana Basin (-14 mmboe). 

• New economic scenario also affected scheduled projects economics, resulting in a 20 mmboe Proved Undeveloped Reserves reduction mainly from oil 
fields of Neuquina basin (-15 mmboe) and Golfo San Jorge Basin (-3 mmboe). 

• Total liquids and gas production performance from existing wells was better than expected, resulting in an addition of 25 mmboe to proved developed 
reserves, according to new reserves estimates. Upward revisions of 48 mmboe are primarily due to better than expected well performance mainly in the 
Neuquina  basin  (31  mmboe)  and  Golfo  San  Jorge  basin  (14  mmboe).  Downward  revisions  of  approximately  23  mmboe  are  mainly  related  to 
performance updates in certain wells in the Neuquina basin. 

• A total volume of 5,6 mmboe of proved reserves was added due to feasibility studies performed to include new projects to field development plans, 
mainly in Golfo San Jorge basin (3,5 mmboe) and Neuquina basin (2,1 mmboe). 

•  Net  production  results  and  forecasts  from  some  new  wells  were  lower  than  expected,  resulting  in  a  7  mmboe  reduction  of  proved  reserves.  Main 
differences were found in Nequina and Golfo San Jorge basins. 

• As a better than expected WO jobs performance, 4.2 mmboe of Proved Reserves were added, mainly in Golfo San Jorge and Neuquina basins.

SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED) (Cont.) 

Changes in our estimated proved reserves during 2016 

Extensions and Discoveries 

As a result of wells drilled in unproved reserves and resources areas, approximately 42 mmboe of proved developed reserves (15.5 mmbbl of crude oil, 
3.8 mmbbl of NGL and 128.8 bcf of natural gas), and 79 mmboe of proved undeveloped reserves (29 mmbbl of crude oil, 7 mmbbl of NGL and 242 bcf 
of natural gas) were added. 

The main proved undeveloped reserves additions are related to non-conventional and tight gas activities in the Neuquina basin, while proved developed 
reserves contributions are mainly from projects in the Neuquina and Golfo San Jorge basins. 

Improved Recovery 

A  total  of  approximately  35  mmboe  of  proved  reserves  were  added,  mainly  due  to  new  projects  and  positive  production  response.  The  main 
contributions come from the Golfo San Jorge basin (8 mmboe of proved developed and 17 mmboe of proved undeveloped reserves), while 7 mmboe of 
proved developed reserves and 2 mmboe of proved undeveloped secondary recovery reserves were added in the Neuquina basin. 

Sales and Acquisitions 

As  a  net  result  of  sales  and  acquisitions,  30.7  mmboe  of  proved  reserves  (19.5  mmboe  of  proved  developed  reserves  and  11.2  mmboe  of  proved 
undeveloped  reserves)  were  added.  These  reserves  increases  are  related  mainly  to  the  acquisition  of  interests  in  the  Río  Neuquén  and  Aguada  de  la 
Arena fields. 

Revisions of Previous Estimates 

During 2016, the Company’s proved reserves were revised downwards by 89 mmboe (75 mmbbl of crude oil and 110 bcf of natural gas and an increase 
of 5 mmbbl of NGL). 

The main revisions to proved reserves were due to the following: 

• As a result of a lower average oil price in 2016, its impact on incomes, and on the economic limit of fields, 105 mmboe of proved developed reserves 
were  deducted  mainly  from  oil  fields.  Changes  occurred  mainly  in  the  fields  of  the  Golfo  San  Jorge  basin  (-40  mmboe),  the  Neuquina  basin  (-43 
mmboe), the Austral basin (-14 mmboe) and the Cuyana basin (-8 mmboe). 

•  New  economic  conditions  also  affected  the  economics  of  scheduled  projects,  resulting  in  a  45  mmboe  reduction  of  proved  undeveloped  reserves, 
mainly from oil fields of the Golfo San Jorge basin (-16 mmboe), the Neuquina basin (-15 mmboe), the Austral basin  (-12 mmboe) and the Cuyana 
basin (-2 mmboe). 

• Total liquids and gas production performance from existing wells was better than expected, resulting in an addition of 68 mmboe to proved developed 
reserves, according to new reserves estimates. Upward revisions of 80 mmboe are primarily due to better than expected well performance mainly in the 
Neuquina  basin  (27  mmboe)  and  the  Golfo  San  Jorge  basin  (42  mmboe).  Downward  revisions  of  approximately  12  mmboe  are  mainly  related  to 
performance updates in certain wells in the Neuquina basin. 

• A total volume of 12 mmboe of proved reserves was added due to feasibility studies performed to include new field development projects, mainly in 
the Neuquina basin (10 mmboe) and the Golfo San Jorge basin (2 mmboe). 

•  Net  production  and  forecasts  from  some  new  wells  were  lower  than  expected,  resulting  in  a  10  mmboe  reduction  of  proved  reserves.  The  main 
differences were found in the Neuquina, Golfo San Jorge and Austral basins.

SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED) (Cont.) 

Results of operations from oil and gas producing activities 

The following tables include only the revenues and expenses directly associated with oil and gas producing activities. It does not include any allocation 
of the interest costs or corporate overhead and, therefore, is not necessarily indicative of the contribution to net earnings of the oil and gas operations. 

Differences between these tables and the amounts shown in Note 5 “Segment information”, for the exploration and production business unit, relate to 
additional operations that do not arise from those properties held by the Group.

There is no Group’s share in equity method investees’ results of operations during the years ended December 31, 2018, 2017 and 2016. 

Standardized measure of discounted future net cash flows 

The  standardized  measure  is  calculated  as  the  excess  of  future  cash  inflows  from  proved  reserves  less  future  costs  of  producing  and  developing  the 
reserves,  future  income  taxes  and  a  discount  factor.  Future  cash  inflows  represent  the  revenues  that  would  be  received  from  production  of  year-end 
proved reserve quantities assuming the future production would be sold at the prices used for reserves estimates as of year-end (the “average price”). 
Accordingly, crude oil prices used to determine reserves were calculated each month, for crude oils of different quality produced by the Group.

SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED) (Cont.) 

For the year ended December 31, 2018, the Company considered the realized prices for crude oil in the domestic market taking into account the effect of 
export  taxes  as  in  effect  as  of  each  of  the  corresponding  years  (until  2020,  in  accordance  with  Decree  No. 793/2018).  For  the  years  beyond  the 
mentioned periods, the Company considered the unweighted average price of the first-day-of-the-month for each month within the twelve-month period 
ended December 31, 2018, which refers to the Brent prices adjusted by each different quality produced by the Company. 

Additionally, since there are no benchmark market natural gas prices available in Argentina, the Company considered the realized prices in the domestic 
market according to the SEC and FASB’Ss ASC 932 rules, but also taking into account the effect of certain market regulations set forth mainly during 
the second half of the year for certain natural gas segments. 

Future production costs include the estimated expenditures related to production of the proved reserves, plus any production taxes without consideration 
of future inflation. Future development costs include the estimated costs of drilling development wells and installation of production facilities, plus the 
net  costs  associated  with  dismantling  and  abandonment  of  wells,  assuming  year-end  costs  continue  without  consideration  of  future  inflation.  Future 
income taxes were determined by applying statutory rates to future cash inflows less future production costs and less tax depreciation of the properties 
involved. The present value was determined by applying a discount rate of 10% per year to the annual future net cash flows. 

The  future  cash  inflows  and  outflows  in  foreign  currency  have  been  remeasured  at  the  selling  exchange  rate  of  Argentine  pesos  37.60  as  of 
December 31, 2018. 

The standardized measure does not purport to be an estimate of the fair market value of the Group’s proved reserves. An estimate of fair value would 
also take into account, among other things, the expected recovery of reserves in excess of proved reserves, anticipated changes in future prices and costs 
and a discount factor representative of the time value of money and the risks inherent in producing oil and gas.

interest in each asset is shown in Appendix V. This report is intended for inclusion in YPF’s filings (20-F, F-3) with the United States 
Securities and Exchange Commission. 

GCA has conducted an independent audit examination as of December 31, 2018, of the hydrocarbon liquid and natural gas proved 
reserves of 36 units. On the basis of technical and other information made available to GCA concerning these property units, GCA 
hereby provides the reserves statement in the following table:

Notes: 

1. Gross (100%) Field Volumes represents 100% working interest. 

2. YPF Net Reserves represent YPF’s working interest volumes and therefore include volumes related to royalties payable to 
the relevant Argentine provinces. According to YPF’s accounting procedures, royalties are accounted for as a cost of 
production and are not deducted in determining reserves. 

3. Hydrocarbon liquid volumes represent crude oil, condensate, gasoline and NGL estimated to be recovered during field 

separation and plant processing and are reported in millions of stock tank cubic meters (MMm3). 

4. Natural gas volumes represent expected gas sales plus produced gas used for consumption and are reported in billion 

(109) standard cubic meters (Bm3) at standard condition of 15 degrees Celsius and 1 atmosphere. The total YPF Net Proved 
reserves gas volume estimate of 20.7 Bm3 includes 2.0 Bm3 used for fuel. 

5.

Totals may not exactly equal the sum of the individual entries because of rounding. 

This report relates specifically and solely to the subject matter as defined in the scope of work in the Proposal for Services and is 
conditional upon the assumptions described herein. The report must be considered in its entirety and must only be used for the purpose 
for which it was intended. 

Gas reserves sales volumes are based on firm and existing gas contracts, or on the reasonable expectation of a contract or on the 
reasonable expectation that any such existing gas sales contracts will be renewed on similar terms in the future. 

Appendices II and III provide the Gross (100%) Field and YPF Net Reserves for each basin, respectively. 

YPF has advised GCA that the YPF reserves estimated in this report constitute approximately 33.8% percent of YPF’s Proved reserves 
and that the Proved Undeveloped Reserves estimated in this report constitute approximately 45% percent of all of YPF’s Proved 
Undeveloped Reserves as of December 31, 2018. These proportions are on a barrel oil equivalent (BOE) basis. GCA is not in a position 
to verify these statements because it was not requested to review YPF’s other oil and gas assets. Our study was completed on 
February 5, 2019.

Reserves Assessment 

GCA’s audit of the YPF reserves estimates was based on decline curve analysis to extrapolate the production of existing wells or 
prepare type curves to estimate future production from the locations proposed by YPF. Geological information, material balance, fluid 
laboratory tests and other pertinent information was used to assess the reserves estimates and the classification and categorization of the 
volumes to be recovered based on the proposed development plan. 

This audit examination was based on reserves estimates and other information provided by YPF to GCA from September 2018 to 
February 2019 and included such tests, procedures and adjustments as were considered necessary under the circumstances to prepare 
the report. All questions that arose during the course of the audit process were resolved to our satisfaction. 

The economic tests for the December 31, 2018 Proved Reserves volumes were based on realized crude oil, condensate, NGL and 
average gas sales prices as shown in the Appendix IV, as advised by YPF. YPF is subject to extensive regulations relating to the oil and 
gas industry in Argentina, which include specific natural gas market regulations. 

Information on net proved reserves as of December 31, 2018 was calculated in accordance with the SEC regulations1 and Financial 
Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 932, as amended. Accordingly, oil prices 
used to determine volumes and reserves were calculated each month, for crude oils of different quality produced by YPF. Consequently, 
for calculation of volumes and reserves as of December 31, 2018 YPF considered the realized price for crude oil in the domestic market 
taking into account the unweighted average price for each month within the twelve-month period ended December 31, 2018. There 
were no published benchmark crude oil prices during 2018 in Argentina that relate to YPF’s oil production from which 
first-day-of-month prices could be obtained. Additionally, YPF considered that the current export fees will not be in place after 
December 31, 2020 based on the amendments of the legislation promulgated during 2018. Therefore, two set of prices resulted, one for 
2019-2020 which includes export fees, and the other for 2021 and thereafter as indicated in Appendix III. Additionally, since there are 
no benchmark market natural gas prices available in Argentina, YPF used average realized gas prices during the year to derive its 
reserves estimates. GCA reviewed and accepted the methodology and prices used by YPF in estimating the reserves in Argentina. 

Future capital costs were derived from development program forecasts prepared by YPF for the fields. Recent historical operating 
expense data were utilized as the basis for operating cost projections. GCA has found that YPF has projected sufficient capital 
investments and operating expenses to produce economically the projected volumes. 

It is GCA’s opinion that the estimates of total remaining recoverable hydrocarbon liquid and gas volumes at December 31, 2018, are, in 
the aggregate, reasonable and the reserves categorization is appropriate and consistent with the definitions for reserves set out in 
17-CFR Part 210 Rule 4-10(a) of Regulation S-X of the United States Securities and Exchange Commission (as set out in Appendix 
VII). GCA concludes that the methodologies employed by YPF in the derivation of the volume estimates are appropriate and that the 
quality of the data relied upon, the depth and thoroughness of the estimation process are adequate.

Basis of Opinion 

This document reflects GCA’s informed professional judgment based on accepted standards of professional investigation and, as 
applicable, the data and information provided by the Client, the limited scope of engagement, and the time permitted to conduct the 
evaluation. 

In line with those accepted standards, this document does not in any way constitute or make a guarantee or prediction of results, and no 
warranty is implied or expressed that actual outcome will conform to the outcomes presented herein. GCA has not independently 
verified any information provided by, or at the direction of, the Client, and has accepted the accuracy and completeness of this data. 
GCA has no reason to believe that any material facts have been withheld, but does not warrant that its inquiries have revealed all of the 
matters that a more extensive examination might otherwise disclose. 

The opinions expressed herein are subject to and fully qualified by the generally accepted uncertainties associated with the 
interpretation of geoscience and engineering data and do not reflect the totality of circumstances, scenarios and information that could 
potentially affect decisions made by the report’s recipients and/or actual results. The opinions and statements contained in this report are 
made in good faith and in the belief that such opinions and statements are representative of prevailing physical and economic 
circumstances. 

There are numerous uncertainties inherent in estimating reserves and resources, and in projecting future production, development 
expenditures, operating expenses and cash flows. Oil and gas resources assessments must be recognized as a subjective process of 
estimating subsurface accumulations of oil and gas that cannot be measured in an exact way. Estimates of oil and gas resources 
prepared by other parties may differ, perhaps materially, from those contained within this report. 

The accuracy of any resources estimate is a function of the quality of the available data and of engineering and geological interpretation. 
Results of drilling, testing and production that post-date the preparation of the estimates may justify revisions, some or all of which may 
be material. 

Accordingly, resources estimates are often different from the quantities of oil and gas that are ultimately recovered, and the timing and 
cost of those volumes that are recovered may vary from that assumed. 

GCA’s review and audit involved reviewing pertinent facts, interpretations and assumptions made by YPF in preparing estimates of 
reserves. GCA performed procedures necessary to enable it to render an opinion on the appropriateness of the methodologies employed, 
adequacy and quality of the data relied on, depth and thoroughness of the reserves and resources estimation process, classification and 
categorization of reserves and resources appropriate to the relevant definitions used, and reasonableness of the estimates. 

Definition of Reserves 

Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a 
given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable 
expectation that there will exist, the legal right to produce, or a revenue interest in, the production, installed means of delivering oil and 
gas or related substances to market, and all permits and financing required to implement the project. 

4 

Reserves are further categorized in accordance with the level of certainty associated with the estimates and may be sub-classified based 
on project maturity and/or characterized by development and production status. All categories of reserves volumes quoted herein have 
been derived within the context of an economic limit test (ELT) assessment (pre-tax and exclusive of accumulated depreciation 
amounts). 

GCA is not aware of any potential changes in regulations applicable to these fields that could affect the ability of the Client to produce 
the estimated reserves. 

GCA has not undertaken a site visit and inspection because it was not part of the scope of work. As such, GCA is not in a position to 
comment on the operations or facilities in place, their appropriateness and condition, or whether they are in compliance with the 
regulations pertaining to such operations. Further, GCA is not in a position to comment on any aspect of health, safety, or environment 
of such operation. 

This report has been prepared based on GCA’s understanding of the effects of petroleum legislation and other regulations that currently 
apply to these properties. However, GCA is not in a position to attest to property title or rights, conditions of these rights (including 
environmental and abandonment obligations), or any necessary licenses and consents (including planning permission, financial interest 
relationships, or encumbrances thereon for any part of the appraised properties).

SEC Reserves Definitions 

U.S. SECURITIES AND EXCHANGE COMMISSION (SEC) 
MODERNIZATION OF OIL AND GAS REPORTING1

Oil and Gas Reserves Definitions and Reporting 

(a) Definitions 

(1) Acquisition of properties. Costs incurred to purchase, lease or otherwise acquire a property, including costs of lease bonuses and 
options to purchase or lease properties, the portion of costs applicable to minerals when land including mineral rights is purchased in 
fee, brokers’ fees, recording fees, legal costs, and other costs incurred in acquiring properties. 

(2) Analogous reservoir. Analogous reservoirs, as used in resources assessments, have similar rock and fluid properties, reservoir 
conditions (depth, temperature, and pressure) and drive mechanisms, but are typically at a more advanced stage of development than the 
reservoir of interest and thus may provide concepts to assist in the interpretation of more limited data and estimation of recovery. When 
used to support proved reserves, an “analogous reservoir” refers to a reservoir that shares the following characteristics with the reservoir 
of interest: 

(i)

Same geological formation (but not necessarily in pressure communication with the reservoir of interest); 

(ii) Same environment of deposition; 

(iii) Similar geological structure; and 

(iv) Same drive mechanism. 

Instruction to paragraph (a)(2): Reservoir properties must, in the aggregate, be no more favorable in the analog than in the 
reservoir of interest. 

(3) Bitumen. Bitumen, sometimes referred to as natural bitumen, is petroleum in a solid or semi-solid state in natural deposits with a 
viscosity greater than 10,000 centipoise measured at original temperature in the deposit and atmospheric pressure, on a gas free basis. In 
its natural state it usually contains sulfur, metals, and other non-hydrocarbons. 

(4) Condensate. Condensate is a mixture of hydrocarbons that exists in the gaseous phase at original reservoir temperature and pressure, 
but that, when produced, is in the liquid phase at surface pressure and temperature. 

(5) Deterministic estimate. The method of estimating reserves or resources is called deterministic when a single value for each 
parameter (from the geoscience, engineering, or economic data) in the reserves calculation is used in the reserves estimation procedure. 

(6) Developed oil and gas reserves. Developed oil and gas reserves are reserves of any category that can be expected to be recovered: 

(i)

Through existing wells with existing equipment and operating methods or in which the cost of the required equipment is 
relatively minor compared to the cost of a new well; and 

(ii) Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is 

by means not involving a well.

Extracted from 17 CFR Parts 210, 211, 229, and 249 [Release Nos. 33-8995; 34-59192; FR-78; File No. S7-15-08] RIN 3235-
AK00]. 

(7) Development costs. Costs incurred to obtain access to proved reserves and to provide facilities for extracting, treating, gathering and 
storing the oil and gas. More specifically, development costs, including depreciation and applicable operating costs of support 
equipment and facilities and other costs of development activities, are costs incurred to: 

(i) Gain access to and prepare well locations for drilling, including surveying well locations for the purpose of determining 
specific development drilling sites, clearing ground, draining, road building, and relocating public roads, gas lines, and 
power lines, to the extent necessary in developing the proved reserves. 

(ii) Drill and equip development wells, development-type stratigraphic test wells, and service wells, including the costs of 

platforms and of well equipment such as casing, tubing, pumping equipment, and the wellhead assembly. 

(iii) Acquire, construct, and install production facilities such as lease flow lines, separators, treaters, heaters, manifolds, 

measuring devices, and production storage tanks, natural gas cycling and processing plants, and central utility and waste 
disposal systems. 

(iv) Provide improved recovery systems. 

(8) Development project. A development project is the means by which petroleum resources are brought to the status of economically 
producible. As examples, the development of a single reservoir or field, an incremental development in a producing field, or the 
integrated development of a group of several fields and associated facilities with a common ownership may constitute a development 
project. 

(9) Development well. A well drilled within the proved area of an oil or gas reservoir to the depth of a stratigraphic horizon known to be 
productive. 

(10) Economically producible. The term economically producible, as it relates to a resource, means a resource which generates revenue 
that exceeds, or is reasonably expected to exceed, the costs of the operation. The value of the products that generate revenue shall be 
determined at the terminal point of oil and gas producing activities as defined in paragraph (a)(16) of this section. 

(11) Estimated ultimate recovery (EUR). Estimated ultimate recovery is the sum of reserves remaining as of a given date and 
cumulative production as of that date. 

(12) Exploration costs. Costs incurred in identifying areas that may warrant examination and in examining specific areas that are 
considered to have prospects of containing oil and gas reserves, including costs of drilling exploratory wells and exploratory-type 
stratigraphic test wells. Exploration costs may be incurred both before acquiring the related property (sometimes referred to in pail as 
prospecting costs) and after acquiring the property. Principal types of exploration costs, which include depreciation and applicable 
operating costs of support equipment and facilities and other costs of exploration activities, are: 

(i) Costs of topographical, geographical and geophysical studies, rights of access to properties to conduct those studies, and 
salaries and other expenses of geologists, geophysical crews, and others conducting those studies. Collectively, these are 
sometimes referred to as geological and geophysical or “G&G” costs. 

(ii) Costs of carrying and retaining undeveloped properties, such as delay rentals, ad valorem taxes on properties, legal costs for 

title defense, and the maintenance of land and lease records. 

(iii) Dry hole contributions and bottom hole contributions. 

(iv) Costs of drilling and equipping exploratory wells. 

(v) Costs of drilling exploratory-type stratigraphic test wells. 

(13) Exploratory well. An exploratory well is a well drilled to find a new field or to find a new reservoir in a field previously found to 
be productive of oil or gas in another reservoir. Generally, an exploratory well is any well that is not a development well, an extension 
well, a service well, or a stratigraphic test well as those items are defined in this section. 

(14) Extension well. An extension well is a well drilled to extend the limits of a known reservoir. 

(15) Field. An area consisting of a single reservoir or multiple reservoirs all grouped on or related to the same individual geological 
structural feature and/or stratigraphic condition. There may be two or more reservoirs in a field which are separated vertically by 
intervening impervious strata, or laterally by local geologic barriers, or by both. Reservoirs that are associated by being in overlapping 
or adjacent fields may be treated as a single or common operational field. The geological terms “structural feature” and “stratigraphic 
condition” are intended to identify localized geological features as opposed to the broader terms of basins, trends, provinces, plays, 
areas-of-interest, etc. 

(16) Oil and gas producing activities. 

(i) Oil and gas producing activities include: 

(A)

(B)

(C)

The search for crude oil, including condensate and natural gas liquids, or natural gas (“oil and gas”) in their natural 
states and original locations; 

The acquisition of property rights or properties for the purpose of further exploration or for the purpose of removing 
the oil or gas from such properties; 

The construction, drilling, and production activities necessary to retrieve oil and gas from their natural reservoirs, 
including the acquisition, construction, installation, and maintenance of field gathering and storage systems, such as: 

(1) Lifting the oil and gas to the surface; and 

(2) Gathering, treating, and field processing (as in the case of processing gas to extract liquid hydrocarbons); 

and 

(D)

Extraction of saleable hydrocarbons, in the solid, liquid, or gaseous state, from oil sands, shale, coalbeds, or other 
nonrenewable natural resources which are intended to be upgraded into synthetic oil or gas, and activities undertaken 
with a view to such extraction. 

Instruction 1 to paragraph (a)(16)(i): The oil and gas production function shall be regarded as ending at a “terminal point”, which 
is the outlet valve on the lease or field storage tank. If unusual physical or operational circumstances exist, it may be appropriate to 
regard the terminal point for the production function as: 

a.

b.

The first point at which oil, gas, or gas liquids, natural or synthetic, are delivered to a main pipeline, a common 
carrier, a refinery, or a marine terminal; and 

In the case of natural resources that are intended to be upgraded into synthetic oil or gas, if those natural resources are 
delivered to a purchaser prior to upgrading, the first point at which the natural resources are delivered to a main 
pipeline, a common carrier, a refinery, a marine terminal, or a facility which upgrades such natural resources into 
synthetic oil or gas. 

Instruction 2 to paragraph (a)(16)(i): For purposes of this paragraph (a)(16), the term saleable hydrocarbons means hydrocarbons 
that are saleable in the state in which the hydrocarbons are delivered. 

(ii) Oil and gas producing activities do not include: 

(A)

Transporting, refining, or marketing oil and gas; 

(B)

Processing of produced oil, gas or natural resources that can be upgraded into synthetic oil or gas by a registrant that 
does not have the legal right to produce or a revenue interest in such production; 

(C) Activities relating to the production of natural resources other than oil, gas, or natural resources from which synthetic 

oil and gas can be extracted; or 

(D)

Production of geothermal steam. 

(17) Possible reserves. Possible reserves are those additional reserves that are less certain to be recovered than probable reserves. 

(i) When deterministic methods are used, the total quantities ultimately recovered from a project have a low probability of 

exceeding proved plus probable plus possible reserves. When probabilistic methods are used, there should be at least a 10% 
probability that the total quantities ultimately recovered will equal or exceed the proved plus probable plus possible reserves 
estimates. 

(ii) Possible reserves may be assigned to areas of a reservoir adjacent to probable reserves where data control and interpretations 

of available data are progressively less certain. Frequently, this will be in areas where geoscience and engineering data are 
unable to define clearly the area and vertical limits of commercial production from the reservoir by a defined project. 

(iii) Possible reserves also include incremental quantities associated with a greater percentage recovery of the hydrocarbons in 

place than the recovery quantities assumed for probable reserves. 

(iv) The proved plus probable and proved plus probable plus possible reserves estimates must be based on reasonable alternative 
technical and commercial interpretations within the reservoir or subject project that are clearly documented, including 
comparisons to results in successful similar projects. 

(v) Possible reserves may be assigned where geoscience and engineering data identify directly adjacent portions of a reservoir 
within the same accumulation that may be separated from proved areas by faults with displacement less than formation 
thickness or other geological discontinuities and that have not been penetrated by a wellbore, and the registrant believes that 
such adjacent portions are in communication with the known (proved) reservoir. Possible reserves may be assigned to areas 
that are structurally higher or lower than the proved area if these areas are in communication with the proved reservoir. 

(vi) Pursuant to paragraph (a)(22)(iii) of this section, where direct observation has defined a highest known oil (HKO) elevation 

and the potential exists for an associated gas cap, proved oil reserves should be assigned in the structurally higher portions of 
the reservoir above the HKO only if the higher contact can be established with reasonable certainty through reliable 
technology. Portions of the reservoir that do not meet this reasonable certainty criterion may be assigned as probable and 
possible oil or gas based on reservoir fluid properties and pressure gradient interpretations. 

(18) Probable reserves. Probable reserves are those additional reserves that are less certain to be recovered than proved reserves but 
which, together with proved reserves, are as likely as not to be recovered. 

(i) When deterministic methods are used, it is as likely as not that actual remaining quantities recovered will exceed the sum of 

estimated proved plus probable reserves. When probabilistic methods are used, there should be at least a 50% probability that 
the actual quantities recovered will equal or exceed the proved plus probable reserves estimates. 

(ii) Probable reserves may be assigned to areas of a reservoir adjacent to proved reserves where data control or interpretations of 
available data are less certain, even if the interpreted reservoir continuity of structure or productivity does not meet the 
reasonable certainty criterion. Probable reserves may be assigned to areas that are structurally higher than the proved area if 
these areas are in communication with the proved reservoir. 

(iii) Probable reserves estimates also include potential incremental quantities associated with a greater percentage recovery of the 

hydrocarbons in place than assumed for proved reserves. 

(iv) See also guidelines in paragraphs (a)(17)(iv) and (a)(17)(vi) of this section. 

(19) Probabilistic estimate. The method of estimation of reserves or resources is called probabilistic when the full range of values that 
could reasonably occur for each unknown parameter (from the geoscience and engineering data) is used to generate a full range of 
possible outcomes and their associated probabilities of occurrence. 

(20) Production costs. 

(i) Costs incurred to operate and maintain wells and related equipment and facilities, including depreciation and applicable 
operating costs of support equipment and facilities and other costs of operating and maintaining those wells and related 
equipment and facilities, they become part of the cost of oil and gas produced. Examples of production costs (sometimes 
called lifting costs) are: 

(A) Costs of labor to operate the wells and related equipment and facilities. 

(B) Repairs and maintenance. 

(C) Materials, supplies, arid fuel consumed and supplies utilized in operating the wells and related equipment and 

facilities. 

(D) Property taxes and insurance applicable to proved properties and wells and related equipment and facilities. 

(E) Severance taxes.

(ii) Some support equipment or facilities may serve two or more oil and gas producing activities and may also serve 

transportation, refining, and marketing activities. To the extent that the support equipment and facilities are used in oil and 
gas producing activities, their depreciation and applicable operating costs become exploration, development or production 
costs, as appropriate. Depreciation, depletion, and amortization of capitalized acquisition, exploration, and development 
costs are not production costs but also become part of the cost of oil and gas produced along with production (lifting) costs 
identified above. 

(21) Proved area. The part of a property to which proved reserves have been specifically attributed. 

(22) Proved oil and gas reserves. Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and 
engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known 
reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which 
contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether 
deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the 
operator must be reasonably certain that it will commence the project within a reasonable time. 

(i)

The area of the reservoir considered as proved includes: 

(A) The area identified by drilling and limited by fluid contacts, if any, and 

(B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with 

it and to contain economically producible oil or gas on the basis of available geoscience and engineering data. 

(ii)

In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons 
(LKH) as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes 
a lower contact with reasonable certainty. 

(iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for 

an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if 
geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty. 

(iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not 

limited to, fluid injection) are included in the proved classification when: 

(A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the 

reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other 
evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the 
project or program was based; and 

(B) The project has been approved for development by all necessary parties and entities, including governmental 

entities. 

(v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. 
The price shall be the average price during the 12-month period prior to the ending date of the period covered by the report, 
determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, 
unless prices are defined by contractual arrangements, excluding escalations based upon future conditions. 

(23) Proved properties. Properties with proved reserves. 

(24) Reasonable certainty. If deterministic methods are used, reasonable certainty means a high degree of confidence that the quantities 
will be recovered. If probabilistic methods are used, there should be at least a 90% probability that the quantities actually recovered will 
equal or exceed the estimate. A high degree of confidence exists if the quantity is much more likely to be achieved than not, and, as 
changes due to increased availability of geoscience (geological, geophysical, and geochemical), engineering, and economic data are 
made to estimated ultimate recovery (EUR) with time, reasonably certain EUR is much more likely to increase or remain constant than 
to decrease. 

(25) Reliable technology. Reliable technology is a grouping of one or more technologies (including computational methods) that has 
been field tested and has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation 
being evaluated or in an analogous formation. 

(26) Reserves. Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically 
producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there 
must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means 
of delivering oil and gas or related substances to market, and all permits and financing required to implement the project. 

Note to paragraph (a)(26): Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until 
those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly 
separated from a known accumulation by a non-productive reservoir (i.e., absence of reservoir, structurally low reservoir, or 
negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered 
accumulations). 

(27) Reservoir. A porous and permeable underground formation containing a natural accumulation of producible oil and/or gas that is 
confined by impermeable rock or water barriers and is individual and separate from other reservoirs. 

(28) Resources. Resources are quantities of oil and gas estimated to exist in naturally occurring accumulations. A portion of the 
resources may be estimated to be recoverable, and another portion may be considered to be unrecoverable. Resources include both 
discovered and undiscovered accumulations. 

(29) Service well. A well drilled or completed for the purpose of supporting production in an existing field. Specific purposes of service 
wells include gas injection, water injection, steam injection, air injection, salt-water disposal, water supply for injection, observation, or 
injection for in-situ combustion. 

(30) Stratigraphic test well. A stratigraphic test well is a drilling effort, geologically directed, to obtain information pertaining to a 
specific geologic condition. Such wells customarily are drilled without the intent of being completed for hydrocarbon production. The 
classification also includes tests identified as core tests and all types of expendable holes related to hydrocarbon exploration. 
Stratigraphic tests are classified as “exploratory type” if not drilled in a known area or “development type” if drilled in a known area. 

(31) Undeveloped oil and gas reserves. Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered 
from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. 

(i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably 

certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of 
economic producibility at greater distances. 

(ii) Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating 

that they are scheduled to be drilled within five years, unless the specific circumstances, justify a longer time. 

(iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of 
fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by 
actual projects in the same reservoir or an analogous reservoir, as defined in paragraph (a)(2) of this section, or by other 
evidence using reliable technology establishing reasonable certainty. 

(32) Unproved properties. Properties with no proved reserves.
