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 expenditures, business, strategy, 
geographic concentration, cost savings, investments and dividends payout policies. These statements are not a guarantee of future 
performance and are subject to material risks, uncertainties, changes and other factors which may be beyond our control or may be 
difficult to predict. Accordingly, our future financial condition, prices, financial ratios, results of operations, business, strategy, 
geographic concentration, production volumes, reserves, capital expenditures, cost savings, WACC (weighted average cost of capital) 
investments and ability to meet our long-term sales commitments or pay dividends or service our outstanding debt could differ

“Item 3. Key Information—Risk Factors” and “Item 5. Operating and Financial Review and Prospects.” YPF does not undertake to 
publicly update or revise 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.

Key Information 

Selected Financial Data 

The following tables present our selected financial data. This information should be read in conjunction with our Audited 

Consolidated Financial Statements, and the information under “Item 5. Operating and Financial Review and Prospects” included 
elsewhere in this annual report. 

Our Audited Consolidated Financial Statements are prepared in accordance with International Financial Reporting Standards 

(“IFRS”) as issued by the International Accounting Standards Board (“IASB”). 

In this annual report, except as otherwise specified, references to “$,” “U.S.$” and “dollars” are to U.S. dollars, and references to

la República Argentina) (the “Central Bank”) on December 31, 2017 of Ps. 18.77 to U.S.$1.00, unless otherwise specified. The 
exchange rate quoted by the Central Bank on April 19, 2018 was Ps. 20.16 to U.S.$1.00. The U.S. dollar equivalent information should 
not be construed to imply that the peso amounts represent, or could have been or could be converted into U.S. dollars at such rates or 
any other rate. See “—Exchange Rates.” 

The financial data contained in this annual report as of and for the years ended December 31, 2017, 2016 and 2015 has been

For information regarding macroeconomic conditions such as exchange rates and inflation rates that affected our results of 
operations, see “Item 3. Key Information—Selected Financial Data—Exchange Rates” and “Item 5. Operating and Financial Review 
and Prospects—Factors Affecting Our Operations—Macroeconomic conditions.” In addition, for an explanation of our results of

Exchange Rates 

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 

9 

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 18.4% from December 31, 2016 to December 31, 2017, 
based on the period-end exchange rates for U.S. dollars as of December 31, 2017 and 2016. See “—Risk Factors—Risks Relating to 
Argentina—Our business is highly dependent upon economic conditions in Argentina.” 

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 Argentine pesos.

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 1570/01, 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. 

10 

On June 9, 2005, by means of Decree No. 616/2005, the Argentine Executive Branch 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 US 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” 6037, substantially modifying existing exchange regulations and facilitating access to the Free Single 
Exchange Market (Mercado Unico Libre de Cambios—“MULC”). On May 19, 2017, the Central Bank issued Communication “A” 
6244 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 / 
05, and maintaining the validity of the norms related to information regimes, surveys or follow-ups related to such topics. 

Recently, through Communication “A” 6401 of December 26, 2017, the Central Bank replaced the information regimes and surveys 
established by Communications “A” 3602 and “A” 4237 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 plurilateral 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 are 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. 

As a result, as of the date of this annual report, the Argentine government has eliminated the restrictions on access to the MULC 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. 

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” 3636 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.

legal advisors and read the applicable rules mentioned herein, as well as their amendments and complementary regulations, which are 
available at the website: http://www.infoleg.gob.ar/, or the Central Bank’s website: www.bcra.gov.ar, as applicable. Information

Risk Factors 

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. 

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 would not differ from your interests as a 
shareholder. In addition, according to the Argentine Constitution, presidential elections take place every four years. 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 subsequent 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 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 2017 the Argentine alternative consumer price index 
(“CPI”) and the wholesale price index increased by 24.8% and 18.8%, respectively. 

12 

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; 

levels of consumer consumption; 

foreign and domestic investment and financing; and 

the rate of inflation. 

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 the elimination of exchange restrictions, the partial adjustment of gas and 
electricity prices and the elimination or reduction of export taxes for certain products, Argentina’s economy continues to face 
challenges. Inflation remains a challenge for Argentina given its persistent nature in recent years. The Macri administration has 
announced its intention to reduce the primary fiscal deficit as a percentage of GDP over time and also reduce the Government’s reliance 
on Central Bank financing. 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 and have an adverse effect on Argentina’s economy and, 
indirectly, our business, financial condition and results of operations. Inflation can also lead to an increase in the Republic’s debt and 
have an adverse effect on the Republic’s ability to service its debt, principally 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 
current macroeconomic program, which has been and is also expected to require domestic and international financing, in the future, the 
Argentine Republic may not be able or willing to access international or domestic capital markets, and the Republic’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 may consequently 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. 

In 2005, Argentina restructured a substantial portion of its bond indebtedness with approximately 76% of its bondholders, and in 
2006 it settled all of its debt with the International Monetary Fund (“IMF”). In June 2010, Argentina restructured additional defaulted 
bond indebtedness that was not swapped in 2005. As a result of the 2005 and 2010 debt swaps, over 92% of the bond indebtedness on 
which Argentina had defaulted in 2002 has been restructured (“Exchange Bonds”). 

Certain holders of bonds that were not swapped in the debt restructuring sued Argentina for payment (“Holdout Bondholders”). 

After several years, in February 2016, Argentina negotiated and reached agreements in principle with respect to a substantial number of 
the Holdout Bondholders. On April 22, 2016, Argentina issued U.S.$16.5 billion of new debt securities in the international capital 
markets, and applied U.S.$9.3 billion to satisfy settlement payments on agreements with holders of approximately U.S.$8.2 billion 
principal amount of defaulted bonds. The District Court ordered the vacatur of all pari passu injunctions upon confirmation of such 
payments. For additional information related to the evolution of the Argentine economy see “Item 5. Operating and Financial Review 
and Prospects—Factors Affecting Our Operations—Macroeconomic conditions.” 

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

Argentina is an emerging market economy, and 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. 

13 

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. 

14 

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. Argentina’s economy remains vulnerable to external shocks, 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. 

Although the Argentine government recently eliminated export taxes to hydrocarbon products, including crude oil, in the past, the 
Argentine government established export taxes on certain hydrocarbon products. 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 regulations of this nature will not be reinstated or modified in the future or that other 

new taxes or import 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. 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 Argentine peso declined approximately 40% against the U.S. dollar. The peso may fluctuate in the future. 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 income are related to the accounting treatment of (i) deferred income 
tax related mainly to fixed assets, which we expect would have a negative effect; (ii) current income tax, which we expect would have a 
positive effect; (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 based on international prices (See “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. 

15 

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, 2017, approximately 22% 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. See “Item 4. Information on the 
Company—Legal and Regulatory Framework and Relationship with the Argentine Government—Repatriation of Foreign Currency.” 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. Following these 
changes, the 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 April 19, 2018, the peso fell to Ps. 20.16 per U.S.$1.00, an increase of approximately 7.4% compared to December 31, 
2017. 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. 

International investors consider Argentina to be an emerging market. Economic and market conditions 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 recent liberalization of the domestic market, 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. 

After the above mentioned recent liberalization of the domestic market, our pricing policy of fuels depends on several factors such 

as international crude oil prices, international refining spreads, processing and distribution costs, biofuel prices, exchange currencies, 
local demand and supply, competition, stocks, local taxation, and domestic margins for our products, among others. Notwithstanding 
our expectation to substantially maintain our domestic prices with reference to those in international markets (see “Item 5. Operating 
and Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions”), we cannot assure you that 
other factors that are also considered into account in our pricing policy as mentioned before, lead us not to completely reflect import 

parity prices in our domestic prices, thus affecting our business, results of operations and financial condition. In addition, substantial or 
extended declines in international crude oil prices or its derivatives, , may also have a material adverse effect on our business, results of 
operations and financial condition. 

16 

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. The 
Argentine government has adopted a policy geared towards the convergence between domestic prices for crude oil and related products 
and international benchmark prices for such products. This convergence finally occurred during the second semester of 2017 (see “Item 
5. Operating and Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions”). 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 cause reduce 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, this change 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. 

Furthermore, we may be required to further write down the carrying value of our properties if estimated oil prices decline or if we 
have substantial downward adjustments to our estimated proved reserves, increases in our operating costs, increases in the discount rate 
of return, 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, including 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. 

In addition, until recently domestic prices for crude oil and certain oil products were not closely co-related or linked to those prevailing 
in international market. The Argentine government has adopted a policy geared towards the convergence between domestic prices for 
crude oil and related products and international benchmark prices for such products. This convergence finally occurred during the 
second semester of 2017 (see “Limitations on local pricing in Argentina may adversely affect our results of operations” and “Item 5. 
Operating and Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions”). Therefore, 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. See “Item 4. Information on the Company—Legal and Regulatory Framework and Relationship 
with the Argentine Government—Market Regulation—Natural gas”; 

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; 

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 at lower prices. 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.” Moreover, 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. 

In the past, due to regulatory, economic and government policy factors, our domestic gasoline, diesel, natural gas and other fuel 

prices have 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 January 2017, the Argentine government adopted a policy geared towards the convergence 
between domestic prices for crude oil and related products and international benchmark prices for such products and in October 2017 
eliminated the price-setting system for domestically-consumed fuel, which led to the current free float of fuel prices. (see “Item 5. 
Operating and Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions”). After the above 
mentioned recent liberalization of the domestic market, our pricing policy of fuels depends on several factors such as international crude 
oil prices, international refining spreads, processing and distribution costs, biofuel prices, exchange currencies, local demand and 
supply, competition, stocks, local taxation, and domestic margins for our products, among others. Notwithstanding our expectation to 
substantially maintain our domestic prices with reference to those in international markets (see “Item 5. Operating and Financial 
Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions”), we cannot assure that we will be successful 
in implementing this policy, as a result of different factors (such as, among others, strong competition or new regulatory or potential 
legal limitations). 

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”) 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. In addition, a 
new stimulus program for natural gas production from non-conventional reservoirs was created (see “Item 4. Information on the 
Company—Legal and Regulatory Framework and Relationship with the Argentine Government—MINEM Resolution No. 46/2017”). 
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 “Item 4. Information on the Company—Legal and Regulatory Framework and Relationship with 
the Argentine Government—Market Regulation.” 

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, 2017 are set forth in Note 31 to the Audited Consolidated Financial Statements, including those related to the 
Natural Gas Additional Injection Stimulus Program. As of December 31, 2017, the accounts receivable balance corresponding to the 
Natural Gas Additional Injection Stimulus Program reflects twelve months of accrued, unpaid payments, representing Ps. 13.4 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, 2017 under such programs. See additionally “Item 4. Information on the Company—Legal and Regulatory Framework 
and Relationship with the Argentine Government— MINEM Resolution No. 97/2018.”. 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 may delay collection of working capital payments in excess of our estimates, our 
financial condition and results of operations could be adversely affected. 

18 

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. 

During the last several years, 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 
Argentine Secretariat of Energy 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, 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. 

19 

We are unable to predict 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 2017 compared to 2016 by 3.9% and our reserves replacement ratio 
(increases in reserves in the year, net divided by the production of the year) was 9% in 2017, compared to 46% in 2016. 

20 

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 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 and may 
prove unsuccessful. 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 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, 2017, 2016 and 2015 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, the Argentine government has adopted a policy geared towards the convergence between domestic prices 

for crude oil and related products and international benchmark prices for such products. This convergence finally occurred during the 
second semester of 2017. See “Item 5. Operating and Financial Review and Prospects—Factors Affecting Our 
Operations—Macroeconomic conditions”. Accordingly, for calculations of our net proved reserves as of December 31, 2017, we 
considered the realized prices for crude oil in the domestic market, taking into account the unweighted average price for each month 
within the twelve-month period ending December 31, 2017. 

The international price of crude oil has fluctuated significantly in the past. If these prices decrease significantly in the future, 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. Holding all other factors constant, if commodity reference prices 
used in our year-end reserve estimates were decreased by 10% for crude oil, our total proved reserves as of December 31, 2017 would 
decrease by approximately 12.3%. Furthermore, holding all other factors 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, 2017 would decrease by approximately 
11.7%. 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 oil products” 

21 

Oil and gas activities are subject to significant economic, environmental and operational risks. 

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 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 during the year, particularly as a result of increased 
demand for natural gas during the colder winter months. In the fourth quarter of 2017, an unusually lower natural gas demand forced us 
to reduce natural gas output. We could be subject to seasonal fluctuations in our sales volumes and consequently our level of natural gas 
production could be negatively affected. (See “Item 5. Operating and Financial Review and Prospects—Factors Affecting Our 
Operations—Seasonality.”) 

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. 

22 

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 “—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. 
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. Under the Hydrocarbons Law, non-compliance with the 
obligations and standards set out therein 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. 

Our acquisition of exploratory 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. As a result, the conditions under which we are able to access new exploratory or productive 
areas could be adversely affected. In addition, fewer offerings of exploratory acreages available to be bid upon could affect our future 
results. 

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. In addition, we or YPF Holdings, our wholly-owned 
subsidiary, may have certain environmental liabilities through certain subsidiaries. See “—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.” 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. 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.” 

23 

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 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. 

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 giving notice 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 (“Pospetition DIP Facility”) under the Alternative Plan, the 
Judge ordered the repayment of the outstanding amounts (approximately US$12.2 millon) 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. The Liquidating Trust stated to 
the Bankruptcy Court that it intends to file claims in 2018. 

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.” 

24 

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. 

25 

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 to, 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 “—Oil and gas prices, 
including the recent decline in global prices for oil and gas, could affect our business” 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 30, 2015, our shareholders approved a dividend of Ps.503 million (Ps.1.28 per share or ADS), which was paid during 
July 2015. 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 March 2, 2018, our Board of Directors proposed a dividend of Ps. 1.200 million. Our next 
shareholder’s meeting, to be held on April 27, 2018, 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. 

26 

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 has increased, cyber incidents, including deliberate attacks or unintentional events, have 

also increased in the world. 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 have extended 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 
(Eg: 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. For 
example, during the last fiscal year we have increased the budget assigned to cyber security. 

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. 

In the past we have been the target of many attack attempts and we are exposed to malware infections like other companies in the 
industry, which did not result in a significant loss. 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. 

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 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 has not entered into any derivative arrangement. Notwithstanding, in case we 
were to evaluate and decide to enter into contracts of this nature, 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. 

27 

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 and the level and outcome of future drilling activity, 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. 

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. 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. 

28 

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 merger, an acquisition that results in the purchaser holding 15% or more of our capital stock or 
an acquisition that results in the purchaser holding a majority of our capital stock, requiring consequently the approval of the National 
State (the holder of our Class A shares) for such decisions. 

In addition, under our by-laws, an acquisition that results in the purchaser holding 15% or more of our capital stock would require 

such purchaser to make a public cash 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. 

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 pesos on the 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 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. 

29 

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 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 
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 as to voting 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, and Class D shares represented by ADSs may not be voted as you desire. Class D shares represented by 
ADSs for which the depositary fails to receive timely voting instructions may, if requested by us, be voted as we instruct at the 
corresponding meeting. 

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 pesos. The 
peso has historically and recently fluctuated significantly against many major world currencies, including the U.S. dollar. A devaluation 
of the 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, our controlled company (see “Item 4—Information of the 

Company—Gas and Power—YPF in Power Generation.”). In 2017, we had consolidated revenues of Ps. 252,813 million and 
consolidated net profit of Ps. 12,672 million. 

30 

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. 

Repsol YPF owned approximately 99% of our capital stock from 2000 until 2008, when Petersen Energía (“PEISA”) aquired 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 the Argentine Oil and Gas Business and Our Business—We face risk relating to certain 
legal proceedings” for a description of the Repsol Agreement relating to compensation for the expropriation of 51% of the share capital 
of YPF owned, directly or indirectly, by Repsol. 

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. 

31 

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’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 disciplined corporate portfolio management 

• 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, 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 2017 activity. 

Upstream Operations 

• As of December 31, 2017, we held interests in 112 oil and gas fields in Argentina. According to the Ministry of Energy and 
Mining, in 2017 these assets accounted for approximately 49.7% of the country’s total production of crude oil, excluding 
NGLs, and approximately 42.6% of its total natural gas production, including NGLs. 

• We had proved reserves, as estimated as of December 31, 2017, of 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 such 
date, compared to approximately 592 mmbbl of oil, including condensates and NGLs, and approximately 2,924 bcf of gas, 
representing aggregate reserves of approximately 1,113 mmboe as of December 31, 2016. 

•

In 2017, we produced approximately 83 mmbbl of oil (approximately 228 mbbl/d), including condensates, approximately 18 
mmbbl of NGLs (approximately 50 mbbl/d), and approximately 568 bcf of gas (approximately 1,556 mmcf/d), representing 
a total production of approximately 203 mmboe (approximately 555 mboe/d), compared to approximately 90 mmbbl of oil 
(approximately 245 mbbl/d), including condensates, approximately 19 mmbbl of NGLs (approximately 52 mbbl/d), and 
approximately 576 bcf of gas (approximately 1,573 mmcf/d), representing a total production of approximately 211 mmboe 
(approximately 577 mboe/d) in 2016. 

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, 2017 consisted of 1,563 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 35.3% 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. 

32 

Gas and Power Operations 

• We are the largest producer of natural gas in Argentina with total natural gas sales of 14,544.2 mmcm in 2017, accounting 

for 30.1% of the market. 

• We participated in three power generation plants with an aggregate installed capacity of 1,367 MW. In addition, 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, 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 is expected to be 
finished by 2018 with the generation of 99 MW. 

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”) and 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. On March 20, 2018, 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.), subscribed for shares of YPF Energía Eléctrica S.A. (“YPF EE”) in an amount equal to 
24.99% of YPF EE’s capital stock through a cash contribution of US$ 275,000,000, plus a contingent payment for up to

The Argentine Market 

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

on 2016 production, according to the 2017 edition of the BP Statistical Review of World Energy, published in June 2017. 

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 2015, the preliminary GDP growth rate for 2016 and the preliminary GDP growth rate for 2017 published by 
INDEC were positive 2.6%, negative 2.3% and positive 2.9%, 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 Executive Branch 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 2017 its net imports of diesel 
amounted to approximately 2,131 mcm, according to preliminary information provided by the Argentine Secretariat of Energy. 
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 (which evidenced a substantial reduction since mid-2014), all of which 
caused a gradual 6% reduction in the prices of sales of Medanito and Escalante crude oil on the local market (2% monthly as of August 
2016). 

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

Upstream overview 

Development and Exploration Upstream projects represent our integrated vision of optimal field development, identifying each 
project’s reserves category, stage of maturity, risk and strategy. 

In addition to development projects for proved reserves, our portfolio of projects is composed of more than 280 new integral 
development projects, including new Vaca Muerta developments, which gives us the opportunity for considerable growth of our proved 
reserves. In line with this objective, we are planning a massive pilot phase to develop 13 differents clusters in the Non Conventional 
zone. We also have a portfolio of visualized exploratory opportunities which includes more than 700 cases related to contingent and 
prospective resources that contemplate potential development in the event of exploratory success. 

The international and local situation challenges us to adjust our efficiency and costs to be sustainable. In that context, it is critical that 
our portfolio of projects and the production and development of initiatives to reduce costs for our operations and investments are 
properly executed. Part of those initiatives are related to labor efficiency, where we have started to work with labor unions and the 
Argentine government and entered into addenda to the labor agreements with various unions during 2016, as well as the Santa Cruz and 
Chubut agreement during 2017, both aiming for a reduction of development costs. See “Item 6. Directors, Senior Management and 
Employees—Employee Matters.” 

Our business growth objectives, whereby we seek to maximize the productivity and profitability of our portfolio, are based on the 
following key concepts: the rejuvenation of mature fields, an ongoing focus on gas development and the intensive development of 
unconventional reservoirs. See “Item 3. Key Information—Risk Factors.” 

The projects selected to be pursued and their schedules for completion are periodically determined by a portfolio optimization process, 
in accordance with our strategic guidelines. 

Meeting the challenge of the mature oil and gas fields 

Most of our oil and gas producing fields in Argentina are mature, requiring strong commitments to overcome their decline. 

During recent years, we have been working in mature areas that present profitable opportunities for increases in 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 Neuquén basins. 

37 

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. 

We have managed, through the extension of most of our concessions with relatively favorable terms and conditions, to continue with 
the development of strategic water-flooding and improved oil recovery projects, improving our perspectives of production and reserves. 
Nevertheless, we cannot assure you that our efforts will achieve the expected results, mainly because of the risks related to our activities 
(See “Item 3. Key Information—Risk Factors—Risks Relating to the Argentine Oil and Gas Business and Our Business.”). 

In addition, we are also focused on producing and developing initiatives related to reducing costs, in operating expenses and capital 
expenditures. 

Nevertheless, the financial viability of these investments and reserve recovery efforts will generally depend on prevailing economic and 
regulatory conditions in Argentina, as well as the market prices of hydrocarbon products. See “Item 3. Key Information—Risk Factors.” 
and “Item 5. Operating and Financial Review and Prospects—Factors Affecting Our Operations” for additional information regarding 
2018 activity. 

Staying the Path of Unconventional Resources 

During 2017, we continued extending our leadership in this area. 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 500 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 13% in 2017 compared to 2016, we 
expect to continue yielding substantial 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 2018 
activity. 

Tight sands in Rincón del Mangrullo and Aguada de la Arena also contributed to the increase of natural gas production and reserves in 
2017. 19 wells were drilled in these marine tight sands, increasing gas production to 4.2 mmcm/d. 

The important 57 km long evacuation gas pipeline built between Rincón del Mangrullo and the facilities of Loma La Lata, today allows 
gas evacuation of the tight development of the Rincón del Mangrullo block and the shale pilots in the Rincón del Mangrullo and La 
Ribera. During 2017, the construction of a 16 inch loop commenced to this gas pipeline that will allow the evacuation of the gas coming 
from the shale development of these and other areas of this zone. 

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.

We are planning a pilot in 2018 using domestic sand from a quarry in Rio Negro (200 km from Añelo city) which we expect will allow 
to get higher reductions in well cost. 

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. 

Vaca Muerta Formation 

38 

• 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 2017, 27 horizontal wells were drilled and 30 horizontal wells were put into production, achieving a performance that, on 
average, met the expectations set by the Type Well. The well design has been gradually changing, from 1,500 m of lateral length and 18 

frac stages to 2,500 m of lateral length and 32 frac stages (while the space between frac stages was maintained at 80 m), in order to 
continue the reduction of the development cost. 

39 

The Cocina target (deeper productive interval within Vaca Muerta formation) was re-incorporated as a productive interval and is 
expected to double the potential area for drilling. Also, the first infill well to the Cocina was drilled in order to analyze the opportunity 
to develop this target in areas where only wells to the Organico (productive interval within Vaca Muerta formation) were drilled. We 
commenced drilling of a longer lateral well of 3,200 m of lateral length in November 2017. This well was successfully drilled and 
established a national record. Its stimulation is planned for April 2018. Two horizontal wells of 2,000 m targeting Organico and Cocina 
were drilled and completed in the southeast zone of Loma Campana. Those two wells were successfully stimulated in December 2017 
and are expected to start production during the first quarter of 2018. The goal of these activities is data acquisition to incorporate the 
area into the development plan. 

Due to continued improvements in our drilling performance, drilling time was reduced by 21% between 2015 and 2017. An average 
drilling time of 35 days to drill a 4700 m measured depth (“MD”) well was achieved during 2015, with an improvement to 29 days for a 
4800 m MD in 2016 and an improvement to 22 days for a 4800 m MD in 2017. This reduction in drilling time is also reflected in 
drilling costs of an average well cost reduction of 13% between 2016 and 2017 for a horizontal well of 1500 m lateral length and a 
reduction in development cost of 8.3% in the same period. 

In 2017 we conducted various pilots 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 key pilots that we executed to enable 
us to achieve this objective were: 

•

•

Lateral length: A 4 well pilot was executed on a single location to understand the impact to well productivity and well cost 
by increasing well length from 1500m to 2500m. 

Proppant Intensity & Frac Fluid Intensity: A 4 well Design-of-Experiment (DoE) pilot was conducted on a single location at 
varying proppant intensities (lbs/ft) and frac fluid intensities (gals/ft) to identify the incremental well productivity obtained 
per feet of lateral given the incremental cost per additional pound of proppant or gal of fluid, and thereby identify the 
optimum economic point for these two well design variables. 

• Chemical diverter: A chemical diverter pilot was conducted on a single well of a three well pad to understand what 

incremental productivity could be achieved if we could improve the perforation cluster efficiency across a given fracture 
stage. 

• Geosteering (technology that allows the drilling of the horizontal section of the well throughout the productive interval 

without detours): Two geosteering pilots were executed on two different locations in which two wells were geosteered on a 
given location and then compared against two wells on the same location which had not been geosteered. The objective was 
to determine what the incremental productivity gain could be from geosteering within a desired target zone. 

Due its geographical location and its potentially expandable treatment capacity, Loma Campana Crude Oil Treatment Plant became the 
central treatment facility for the Vaca Muerta oil cluster starting in January, 2017. 

In addition, in 2017 a 33 Kilovolt electrical power line, a generation power station and a transformer substation were put on line. These 
facilities allow increasing power and give more reliability to the system as well as facilitating power for neighboring blocks. 

Activity in this area in 2017 involved a gross investment of U.S.$362 million in drilling and completion (D&C) and U.S.$47 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. 
Nine of those wells were put into production with the expected performance (the other 3 wells will be put into production 

40 

in 2018). All of the drilled horizontal drains were standardized at 1,500 m long except for 2 wells that reached 2,000 m. An 
improvement in performance of drilling (time and cost) is still observed, with drilling time and well cost being reduced by 16% and 
21%, respectively, between 2016 and 2017. This drilling and completion activity developed during 2017 comprised a total gross 
investment of U.S.$132 million, with an additional U.S.$41 million expended on production facilities. 

The development phase of the block is estimated to start in September 2018, incorporating a second drilling rig. 

Additionally, both parties in the Investment Agreement ratified their intention to continue with the Pilot in the La Amarga Chica block 
located in the Province of Neuquén. During the third and final phase of the La Amarga Chica Pilot, both companies are considering 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. The joint investment commitment for this third Pilot phase amounts to 192.5 million U.S. Dollars. This phase is 
expected to be completed in the third quarter of 2018, after which both parties will be able to decide on the full development of the 
block. 

During the second half of 2017 the first production battery was put in production with a total gross capacity of 1,000 m3/d. 

We completed the facilities of the southern sector for water supply on a continuous basis (flexipipe) in order to ensure continuous water 
supply when fracturing the PADs with multiple wells (drilling practice that allows drilling multiple wells from a single portion of 
compact land known as PAD). Work associated with the gathering and acquisition of production (internal pipelines and field collectors) 
in the southern and central parts of the area are being executed. In addition, the center and south triangles were connected by an oil 
pipeline, reducing oil transportation and associated production delay. 

An electrical power line was built to provide more reliability to the system, reducing expenses associated with electrical generator 
rentals. 

By the end of 2017, the total oil production increased to 680 m3/d (113% higher than December 2016) with a total of 21 wells in 
production. 

• 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 two vertical and two horizontal wells. Currently one 
vertical and two horizontal wells are in production. Three additional horizontal wells were drilled, one of which being completed by 
December 2017, with performance exceeding expectations. The objective of these wells is to test productivity in different landing zones 
within the Vaca Muerta organic-rich section. These wells will be evaluated during the first months of 2018. 

The standard design for horizontal wells was 2000 m of lateral length and 25 frac stages. 

Additionally, in 2017, the pipeline of dispatch to the PTC LC, the construction of EPF (Early Production Facility) and the point of 
measurement were completed. These facilities allow for evacuating the production of the pilot without the need to use trucks. 

This activity comprised a total investment of U.S.$35.1 million in D&C and U.S.$1.7 million in production facilities. 

• 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 
2017, 78 wells have been drilled and 64 wells have been put on line. During 2017, 19 horizontal wells were drilled reducing the well 
spacing to 300 m at the same landing zone, and 25 wells were put into production, with a gross investment of U.S.$262.2 million in 
D&C and U.S.$24.9 million in production facilities. 

Drilling time and well cost were reduced by 37% and 39%, respectively, between 2016 and 2017, with a reduction in development cost 
of 42.3% in the same period. 

February 2017 marked the start up of the UPS2 (Unidad de Separación Primaria 2), with the treatment and the separation capacity being 
upgraded to 4Mm3/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 (2900 HP installed) and the central compression is planned for December 2018. 

41 

In 2017, the well lateral length was increased to around 2,100 meters. The maximum length drilled was 2,715 meters. The first 6 wells 
inline pad were drilled at beginning of 2017 reducing the drilling and completion costs. The performance of these wells exceeded 
expectations. A space reduction pilot was carried out in the southern area of the block at the higher production performance level. Static 
and Geomechanic Model generation allowed us to select the development zone based on the petrophysical and geomechanical 
properties. 

Regarding the frac plan, new technologies were evaluated such as mechanical diverters and different slickwater frac designs, in order to 
achieve better operational efficiency as well as better well performance. In 2018, a pilot is planned using domestic sand in all hydraulic 
stimulations in order to reduce well cost. In addition, new technologies such as open hole sleeves and high density completion designs 
are expected to be tested. 

By the end of 2017, the total field gas production was 3.9 Mm3/d (105% higher than December 2016). 

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 2017, 88 wells (74 directed wells and 14 horizontal wells) 
were drilled in these marine tight sands, achieving an average gas production of 4.2 mmcm/d through a pipeline that connects to the 
Loma La Lata facilities. During 2016, a pilot of 3 horizontal wells was developed in 2 different zones of very low permeability (very 
tight sand), with results exceeding expectations. These results were encouraging for continued development of horizontal wells. 

During 2017, 11 horizontal wells were drilled in a very tight zone and 8 vertical wells in a tight zone 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 18% and 12%, respectively, between 2016 and 2017, with a reduction in development cost 
of 6% in the same period, with a total investment of U.S.$80.7 million in D&C, and an additional U.S.$17 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. 

In the production facilities, a 16 inch Loop of 33 kms long was started in the existing gas sale pipeline to Loma La Lata to increase gas 
transport capacity. 

This activity, developed during 2017, comprised a total investment of U.S.$34.8 million in D&C and U.S.$1.8 million in production 
facilities. 

• 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, all activity was oriented to the Vaca Muerta formation. One vertical pilot well and three horizontal wells were drilled 
targeting these formation. The objective of the pilot well was data acquisition and landing zone definition. The horizontal wells targeted 
three different landing zones across the Vaca Muerta organic rich section. 

Total investment in connection therewith was U.S.$32.3 million in D&C. 

42 

Bajada de Añelo Area: In February 23, 2017, YPF and O&G Developments Ltd. S.A. (hereinafter “O&G”), an affiliate of Shell 
Compañía Argentina de Petróleo S.A., executed an agreement, through which YPF and O&G agreed on the main terms and conditions 
for the joint development of a shale oil and shale gas pilot in two phases. O&G will be the operator of the area. On August 15, 2017, the 
Province of Neuquén authorized the assignments provided for in the Agreement concluded between YPF S.A. and O & G 
Developments Ltd. S.A., an affiliate of Shell Compañía Argentina de Petroleo S.A., with the objective of carrying out the joint 
exploitation of hydrocarbons in the Bajada de Añelo area in the Province of Neuquén. 

Although there was no drilling and completion activity during 2016, YPF acquired 3D seismic data covering 618 km2 in this area. 

Drilling activity in 2017 started in the southeast corner of the block with one vertical pilot well dedicated to data acquisition (core 
across the entire Vaca Muerta organic-rich section and complete suite of logs). By the end of 2017, we commenced drilling three 
horizontal wells, targeting 3 landing zones, were started to drill from the same pad using the skidding methodology. 

The foregoing activity in 2017 comprised a total investment of U.S.$6.6 million. 

La Ribera Area: This block, located in the center on the Neuquén basin, is 100% owned by YPF. The concession area comprises two 
separated regions: La Ribera I, covering 21.85 km2, and La Ribera II, covering 49.8 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 have obtained results in accordance with expectations. 

• 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 1200 m of lateral length at 2400 m 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 play 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 play. 

During 2017, Chevron evaluated the results of the drilled wells, and informed YPF of its interest in continuing to a second phase, which 
was negotiated during the second half of 2017. 

During 2017, Unconventional Regional production was 84.7 mboe/d, representing 15% of YPF’s total production. 

1. 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 2017, we continued tight gas development in different areas of the block and 4 wells were drilled. One of 
those wells and another three production wells drilled in 2016 were put into production in 2017. One of the well drilled in 2016 was 
abandoned and the others produced less than expected. 

Shale project: six shale gas wells were drilled in 2017. These wells are part of a 22 well pre-development project that we expect to 
continue in the following years. Sixteen of these wells are expected to be connected in 2018. 

2. Aguada San Roque block: This block is operated by Total S.A., and YPF holds a 34.11% working interest. 

Shale oil pilot project: two wells were drilled during 2017. These wells are expected to be completed and connected during first quarter 
of 2018. 

3. Other Blocks:

Aguada Pichana Oeste is operated by PAE, and YPF holds a 30% working interest in this block. One well started drilling operations 
during November 2017. Drilling pilot activities are planned to continue in 2018. 

43 

Pampa de las Yeguas I is operated by EXXON, YPF holds a 50% working interest in this block. One well has been drilled in 2017 and 
two more wells are expected to be drilled in 2018 as part of a pilot project. Three wells are expected to be connected in 2019. 

La Calera is operated by Pluspetrol, and YPF holds a 50% working interest. One exploration well was drilled and completed during 
2017. This well is expected to be connected during first quarter 2018. 

Lindero Atravesado is operated by PAE, and YPF holds a 37.5% working interest. During 2017, 19 tight and development wells were 
drilled to the Lajas Formation. Twelve of these wells were put into production in 2017 with performance being less than expected. 

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 2017, 2016 and 2015, 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 with regard to our developed and undeveloped acreage by geographic area as of

(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. 

(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 

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

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, 2017, none of our exploration permits considered as a 
whole, which include undeveloped acreage, will expire in 2018 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 Argentine Secretariat of Energy. 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 willingess 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”.. As of the date of this annual report, negotiations related to Area ENARSA 1 are ongoing. YPF currently participates in 
three offshore blocks in association with ENARSA, which represent approximately 55% of our net 

44 

exploratory undeveloped acreage. We cannot guarantee that as a result of such negotiations we would not decide to relinquish to the 
Argentine Secretariat of Energy 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, amending the Hydrocarbons Law—Exploration and Production.” 

However, as a result of the expiration in 2018 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 2018, we would be required to relinquish approximately 2,600 
km2 of exploratory undeveloped acreage (approximately 6% of our 43,400 km2 of net exploratory undeveloped acreage as of 
December 31, 2017) during 2018. 

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 7,200 km2 of exploratory undeveloped acreage (approximately 17% of our 43,400 km2 of net exploratory undeveloped 
acreage as of December 31, 2017) during 2019 and 2020. 

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, amending 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 2016 production, Argentina is the largest producer of natural gas and the fourth largest producer of crude oil in Central and 
South America, according to the 2017 edition of the BP Statistical Review of World Energy published in June 2017. 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. As of the date of this annual report, a total of 24 sedimentary basins were re-evaluated in the country, 
in the line with (Plan Exploratorio Argentina). The total surface area of the continent represents approximately 408 million acres and 
the total offshore surface area includes 194 million acres on the South Atlantic shelf within the 200-meter line. Of the total 602 million 
acres of the sedimentary basins, a significant part still needs to be evaluated through exploratory and study drilling. 

The following table shows our gross and net interests in productive oil and gas wells in Argentina by basin, as of December 31, 2017:

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. Gross and net wells include one oil well and 
three gas wells with multiple completions. 

45 

As of December 31, 2017, we held 133 exploration permits and production concessions in Argentina. We directly operate 98 of them, 
including 17 exploration permits and 81 production concessions. 

•

Exploration permits. As of December 31, 2017, we held 21 exploration permits in Argentina, 18 of which were onshore 
exploration permits and 3 of which were offshore exploration permits. We had 100% ownership of 8 onshore permits, and our 
participating interests in the remainder varied between 50% and 80%. Our participating interests in the 3 offshore permits varied 
between 30 % and 35%. 

Production concessions. As of December 31, 2017, we had 112 production concessions in Argentina. We had a 100% ownership 
interest in 67 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 10 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 the Argentine Oil and Gas Business and Our 
Business—Our business depends to a significant extent on our production and refining facilities and logistics network.” 

46 

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 (49%) and Golfo San Jorge 

(43%) basins, and approximately 87% of our proved gas reserves in Argentina are concentrated in the Neuquina (79%), and Golfo San 
Jorge (8%) basins. 

Joint ventures and contractual arrangements in Argentina 

As of December 31, 2017, we participated in 11 exploration and 37 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 
98%, 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, 2017, 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, 2017, 2016 and 2015 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, 2017, the Company considered the realized prices for crude oil 
in the domestic market (which were higher than those that had prevailed in the international market), taking into account the 
unweighted average price for each month within the twelve-month period ended December 31, 2017. Additionally, since there are no 
benchmark market natural gas prices available in Argentina, the Company used average realized gas prices during the year to determine 
its gas reserves. 

Notwithstanding the foregoing, commodity prices have declined significantly since 2014. 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 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. 

47 

Technology used in establishing proved reserves additions 

YPF’s estimated proved reserves as of December 31, 2017 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.”

(2) Volumes of natural gas in the table above and elsewhere in this annual report have been converted to barrels of oil equivalent at 

5,615 cubic feet per barrel. 

(3) Proved crude oil and NGL reserves of consolidated entities include an estimated approximately 61 mmbbl of crude oil and 6 mmbl 
of NGLs in respect of royalty payments which, as described above, are a financial obligation or are substantially equivalent to a 
production or similar tax. Proved natural gas reserves of consolidated entities include an estimated approximately 289 bcf in 
respect of such payments. Equity-accounted entities reserves in respect of royalty payments that are a financial obligation or are 
substantially equivalent to a production or similar tax are not material. 

For information regarding changes in our estimated proved reserves during 2017, 2016 and 2015, 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 2017, 2016 

and 2015. 

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. 

This was partially offset by: 

•

Extensions and discoveries, which added 54 mmboe (219 mmscf 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. 

49 

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 mmcf 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 Neuquen 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. 

Changes in our proved undeveloped reserves during 2015 

YPF had estimated a volume of net proved undeveloped reserves of 337 mmboe at December 31, 2015, which represented 

approximately 27% of the 1,226 mmboe total reported proved reserves as of such date. This compares to estimated net proved 
undeveloped reserves of 307 mmboe as of December 31, 2014 (approximately 25% of the 1,212 mmboe total reported proved reserves 
as of such date). 

The approximately 10% net increase in net proved undeveloped reserves in 2015 is mainly attributable to: 

•

•

•

Extensions and discoveries, which added 93 mmboe (24.5 mmbbl of crude oil, 7.3 mmbbl of NGL and 341.8 bcf of 
natural gas) of proved reserves, mainly in the Neuquina basin. 

New project studies and revisions of gas and oil development projects, which added approximately 18 mmboe (7.5 
mmbbl of crude oil, 0.9 mmbbl of NGL and 52.4 bcf of natural gas) of proved undeveloped reserves. The main 
contributions came from fields in the Neuquina, Golfo San Jorge, and Austral basins. 

New improved recovery projects, which added approximately 10 mmbbl of proved undeveloped secondary recovery 
reserves of crude oil. The most important additions belong to the Golfo San Jorge, Neuquina and Cuyana Basins. 

This was partially offset by: 

•

Ongoing successful development activities related to proved undeveloped reserves projects, which allowed a transfer 
of approximately 77 mmboe (29 mmbbl of crude oil, 10.2 mmbbl of NGL and 212 bcf of natural gas) to proved 
developed reserves. The main contributions are related to development wells (51 mmboe), gas compression projects 
(15 mmboe) and improved recovery projects (8 mmboe). 

50 

•

A new joint venture agreement for the Rincón del Mangrullo field resulted in a reduction of approximately 8 mmboe 
(0.3 mmbbl of crude oil, 1.6 mmbbl of NGL and 34.7 bcf of natural gas) of proved undeveloped reserves, due to a 
change in YPF’s working interest in this area. 

YPF’s total capital expenditure to continue the development of reserves was approximately U.S.$4,592 million during 2015, of 

which U.S.$1,557 million was allocated to projects related to proved undeveloped reserves. 

As of December 31, 2015, 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. 

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) 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 reserves estimation 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. 

(b) The Reserves Auditor, who has headed the RA since July 2017, is responsible for overseeing the preparation of the reserves 

estimates and reserves audits conducted by third party engineers. The current director has over 35 years of experience in geology 
and geophysics, reserves estimates, 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 in YPF. 

51 

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 proved reserves estimation 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. 

(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 2017, 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, 2017, and the audited fields contain in 
aggregate, according to our estimates, approximately 262 mmboe proved reserves (90.82 mmboe of which were proved undeveloped 
reserves) as of such date, which represented approximately 28.2% of our proved reserves and 34.1% of our proved undeveloped 
reserves as of December 31, 2017. 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.

(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 6, 6 and 6 mmbbl for the years ended December 31, 2017, 2016 and 2015, respectively. NGL production 
in these fields was approximately 8, 8 and 8 mmbbl for the years ended December 31, 2017, 2016 and 2015, respectively. Natural 
gas production in the Loma La Lata field was 127, 132 and 133 bcf for the years ended December 31, 2017, 2016 and 2015, 
respectively. 

(2) Crude oil production for the years ended in December 31, 2017, 2016 and 2015 includes an estimated 12, 13 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, 2017, 2016 and 2015 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, 2017, 2016 and 2015 includes an estimated 64, 60 and 58 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 2017, our main exploratory and development activities in Argentina have had the following principal focus, 

1. Operated Areas—Exploratory Activities 

During 2017, our exploratory activities in Argentina were mainly focused on: 

1.1 Onshore 

Unconventional activities 

The successful exploration results achieved in 2015 continued into 2016 and 2017. We continued the regional exploration of the 
Vaca Muerta formation to determine the productivity of the wet and dry gas in different areas of the Neuquina Basin. During 
2017, we focused on the regional definition of the shale gas strip area obtaining positive results in Cerro Arena and Salinas del 
Huitrín blocks. Discoveries will be evaluated further in order to establish their commercial production potential. 

• Neuquina Basin: 

Tight gas: Exploration of tight gas continued during 2017 in Estación Fernández Oro, Loma La Lata-Sierra Barrosa and Paso de 

las Bardas Blocks. Positive results were obtained in two wells, three wells continue to be evaluated and work on one well is still 
ongoing. 

Conventional activities 

• Neuquina Basin: 

A total of 13 wells targeting conventional oil and gas reservoirs were drilled in the basin, obtaining seven positive results, in the 

following blocks, 

56 

• Chachahuén (oil) 

•

Señal Picada – Punta Barda (gas). 

Results in six other wells were below expectations. 

From the results obtained in Chachahuén, we have notified the Mendoza Province, and waiting for their answer, of the following: 

Chachahuén Exploration Permit: decision to enter the Third Exploration Period and to relinquish a fixed portion of the area (50%) 
as it is considered non-core lease acreage. 

Chachahuén Norte Evaluation Area: decision to relinquish 40% of the area and the need to extend the permit of the remaining 
acreage until February 2020. 

Chachahuén Sur Evaluation Area: commercial exploitation for part of the block (Cerro Morado Este) and the need to extend the 
permit of the remaining acreage until February 2020. 

We also have requested that the Mendoza province allow commercial exploitation of the Payún Oeste block. As of the date of this 
annual report, we are still awaiting final approval from the province. 

• Golfo San Jorge basin 

During 2017, the exploration activity targeted conventional oil and gas reservoirs in the Golfo San Jorge basin, with positive 
results in two wells in the Cañadón de la Escondida Block (oil). 

We also continued to conduct exploration activities targeting conventional gas in the Escalante—El Trébol Block (where one well 
is currently awaiting termination), Los Perales Block (where one well was completed and is currently being evaluated and a 
second well is close to completion) and Cañadón de la Escondida Block (where one well is currently awaiting termination). 

• Cuyana basin 

One well targeting conventional oil was drilled in Zampal Norte with no positive results and two other wells were drilled in Mesa 
Verde Block (currently under evaluation).Zampal Norte Block: having fulfilled all commitments and considering that the drilled 
well does not show evidence of hydrocarbons, we decided not to continue with the third exploratory period and, as a result, the 
block was relinquished to the province of Mendoza.CCyB 17/B Block: we have been awarded an extension for the 3rd Exploration 
Period until June 2018. 

• Austral basin 

Drilling activities took place in Tierra del Fuego Province. Positive results were obtained in the wells drilled in the Lago Fuego 
Block (gas) and the ones drilled in Tierra del Fuego Fracción “E” Block are currently subject to completion (gas). 

In addition, during 2017 the El Turbio Block has been awarded. Commitments for the First Exploration Period are mainly related 
to seismic activities. 

With respect of Seismic activities a long-term 2D-3D seismic survey campaign began in 2015 and continued through 2016 and 
2017. During 2017, seismic 3D data covering 239 km2 was recorded in Chihuido de la Sierra Negra Block (Neuquén 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 identify new exploration opportunities. 

57 

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 willingnessto 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”. 
As of the date of this annual report, negotiations related to Area ENARSA 1 are ongoing. As of December 31, 2017, we do not 
have registered assets in these blocks. See “—Legal and Regulatory Framework and Relationship with the Argentine 
Government—Law No. 27,007, amending the Hydrocarbons Law” for a description of new terms which apply to new production 
concessions or exploitation permits. 

2. Non-Operated Areas—Exploratory Activities 

Exploration wells have been drilled in La Calera and CNQ-7 Blocks, which are operated by Pluspetrol (both under evaluation) and in 
Aguada Salada, operated by Tecpetrol, with positive results. 

3. Development Activities 

During 2017, our development activities in Argentina were mainly focused, according to the organizational structure in force in 
2017, on the following regions and blocks: 

3.1 Neuquén—Río Negro Region 

During 2017, Neuquén—Río Negro Region production was 218.8 mboe/d, representing 39% of YPF’s total production. 

• Neuquén concession: 

•

Operated Areas—Development Activities: 

1. Octógono block: 

Continuing with the activity of the previous year, during 2017, 5 wells were drilled in the northern sector of the field, targeting 
gas-bearing intervals in the Lajas formation. Four of those had positive results and the other one are being studied for 
optimization. Based on these results in 2018 we plan the development of the field with 6 more wells with Lajas formation as its 
principal objective.

2. Al Norte de la Dorsal block: 

Guanaco field: During 2017, 4 wells were drilled, 3 of them are completed and 1 is in process of completion. All of them targeting gas 
in Lajas formation and their results are still under review. Lajas 2018 training campaign includes the plan to drill 6 more wells in the 
area. The Basamento formations is also planned to be evaluated in 2 wells to determine its potential for future development. To that 
end, we plan to complete and test this formation on 2 of the wells planned to be drill in 2018.

Several actions for well productivity and economic improvement are planned to be conducted in 2018. 

Barda Gonzalez field: During 2017, 1 well was drilled targeting gas in Lajas formation and its result is still under review. If the results 
are positive, the activity on the Lajas formation will continue in 2018 by drilling 1 more well in the area. 

3.

Cerro Bandera Block: 

La Vía field: During 2017, 1 well was drilled targeting gas in Lajas formation. The well is not currently in production (it is without 
facilities), and we made five PLT (Production Logging Tool) studies to determinate its potential. 

On November 22, 2017, YPF entered into an assignment agreement in respect of 100% of the exploitation concession in the Cerro 
Bandera area. See “—Exploration and Production Overview—Main properties.” 

4. Anticlinal Block: 

Bardita Zapala Field: During 2017, 1 well was drilled targeting gas in Chachil formation and its result is still under review.

5.

Loma La Lata – Sierra Barrosa block: 

Loma La Lata field: The Sierras Blancas Infill project in the southeast area continues its development with 5 wells drilled (2 horizontal 
and 3 directional) during 2017. All of them are already in production and the production rate achieved was as expected. 
During 2017 a successful recompletion of a horizontal well, using stage frack technology was performed. 
During 2018, we plan to drill 15 wells and recomplete 4 horizontal wells. 

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

During 2017, 18 wells were drilled in Lajas formation, based on infill development activity. In addition, deeper wells in the Precuyano 
and Los Molles formations are being drilled and tested in two of these infill wells, taking advantage of the low incremental cost as a 
result of the deepening of wells raised to meet our objectives for the Lajas formation. We continue with implementation of several 
actions to reduce well cost successfully not only in the drilling phase, but also in the completion phase, improving project economics. 

A second horizontal well was drilled in the Sierra Barrosa field as part of a pilot to improve the recovery factor in the tightest sands of 
the formation (in the lowest section). It produced gas over expectations 

7.

Barrosa Norte tight gas field (Lajas formation) 

During 2017, three wells were drilled in this area, as a part of a plan to investigate different objectives: Precuyano and Los Molles 
Formation are two of them, also investigating the west structure of the area, and the third, is an infill type well (reducing distancing 
from 40 to 20 acres). The first two successfully confirmed very interesting accumulation for those deep reservoirs, and the infill well 
has verified original pressure and initial gas productivity was better than expected. 

8.

El Triángulo Field (Tordillo formation) 

During 2017 an outpost well was drilled in order to investigate Tordillo formation, and is scheduled to be completed and tested in 2018 
to determine its potential. 

9.

Sierra Barrosa Este tight gas field (Lajas formation) 

During 2017 an outpost well was drilled in nearby structure to Barrosa Norte field. It produced gas at low levels, and failed to achieve 
expected rates. 

10. Loma Campana Block:

The use of new technologies allowed the drilling of a pilot well to evaluate the development of gas and condensate near the gas water 
contact in Sierras Blancas formation. The well was drilled during 2017 and the production rate achieved was as expected. The drilling 
of a second well was completed in early 2018 using the same technology. 

11. 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 6 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). 12 new wells are expected to be drilled in 2018. 

12. Volcán Auca Mahuida and Las Manadas blocks: 

We continued with the appraisal and development of the Centenario and Mulichinco formations from the previous years. Four new 
wells were completed during 2017, two of them being appraisal wells. Positive results were provided by three of the four wells and the 
other one tested dry gas and is currently shut-in. Further appraisal and development wells are scheduled to be drilled in 2018. 

13. Señal Picada – Punta Barda block: 

Piedras Negras field: one exploration well was completed during 2017 and began production in May 2017 and is currently active. Also 
we acquired 210 sq.km of new 3D seismic to the west of the block. No drilling activity is expected during 2018. 

59 

14. Chihuido de la Sierra Negra block: 

Chihuido de la Sierra Negra field: In this mature field, we completed a 3D seismic survey on the western area. Also, in order to 
evaluate tertiary recovery potential, a second single well chemical tracer test and log-inject-log operation (assay technique) was 
performed and it confirmed the previous positive results achieved in 2015 in displacing post water-flooding residual oil by an 
Alkali Surfactant Polymer formulation.

Stage I Increase dispatch capacity to Neuba I (Concessioned gas pipeline) 

Put in operation an LTS (Low Temperature Separator) 

Enlargement network gathering 

With respect to drilling activity, we completed 34 gas wells targeting the Lajas formation (29 development gas wells, and 5 step-out gas 
wells) in general with positive results for the development wells; however, one step-out wells have not yet been evaluated. On 
September 2016, we started to drill with a fourth rig until November 2017, when we reverted to three rigs. 

The development of the gas field will continue during 2018, focusing on drilling activity, 34 new wells are planned to be drilled. 
In addition, work in the first quarter of 2018 to increase the gas pipeline sales capacity has been planned, and an LTS plant of 2 Mm3/d 
capacities. We plan to install it in third quarter 2018. 

17. Señal Picada-Punta Barda block: 

Señal Picada Block: During 2017 only workover activities were performed in this mature oil field, 12 wells were intervened, 6 for gas 
and 6 water injectors. Drilling of new wells is planned for 2018. 

In the Punta Barda area no rig activity was performed in 2017. Three injector wells became active, as they started water injection during 
the first half of 2017. We plan to drill 14 new wells during 2018. 

Six workovers were executed in this block, in order to test gas from the Neuquén Group formation. Four of them proved gas production 
and the other two were dry. 

18. Los Caldenes block: 

Manzano Grande field, oil target: In order to continue with the development activity in the oil block, in early 2018 we plan to drill two 
wells in the Manzano Grande block. No drilling activity was conducted during 2017 in this block. 

Los Caldenes field, gas target: one appraisal well was drilled during 2017, and completion was achieved in 2018. According to well log 
information, reservoir properties are according as expected. A second appraisal well is planned to be completed during first quarter 
2018.

1. Barrancas block: 

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

a.

b.

c.

Barrancas: During 2017, the development of the northwest zone continued in order to expand the area discovered in 
2014, through the drilling of six oil producing wells. The target is the Barrancas Formation. The results of the wells 
drilled in the western flank found the limits of the field. It was also included in this zone a Secondary Recovery 
Project. The Development Plan of the area, including this Secondary Recovery Project, provides for the drilling of 
new producing wells and the conversion of other wells to water injectors during the upcoming years. 

Ugarteche: After ten years without activity in this area, the drilling of two development wells in 2015 showed that 
there were still related opportunities in the Western zone. This scenario allowed the rejuvenation of the area through a 
redefinition of its development plan. As a result, four wells were drilled during 2016 and four wells in 2017, all of 
them with results over expectations. It is expected to continue drilling wells in order to expand the field to the south 
and west. 

Estructura Cruz de Piedra: During 2017, two production wells were drilled with results below expectations, and the 
project of secondary recovery expansion continued through workover activity. It is planned to continue this activity by 
drilling more wells. 

2. 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. 

63 

During 2017, the delineation and development continued through the drilling of nine wells (between advanced and development 

wells), with results according to expectations. The field is not yet fully delineated. The opportunity includes the drilling of development 
and advanced wells during the upcoming years. 

3. La Ventana block: 

Continuing with the activity of the previous years, during 2017, three infill wells were drilled in La Ventana Central area and two 
wells in Vacas Muertas Sur area. The results were below expectations, so the activity has been temporarily suspended, prioritizing other 
opportunities in the block, including the revamping of some surface installations. 

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 or not a pilot project. During 2016 the identification of the ASP (Alcali 
Surfactant Polymer) formulation compatible with the temperature and salinity of the formation was made, while a workover to do a 
single well test is planned for 2018, prior to the possible identification of a tertiary recovery pilot. 

4. Vizcacheras block: 

During 2017, seven wells were drilled to the Barrancas and Papagayos formations, with mixed results (four wells with results over 

expectations and the other three below expectations). 

Four interventions were carried out with radial drilling technology (technique that seeks to increase the productivity of the 
formation), which technically met the stated objective (be able to make the horizontal branches and navigate inside the reservoir), but 
the wells did not respond with the expectation of oil production. 

Additionally, Vizcacheras 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 or not a pilot project. During 2016 the identification of the ASP formulation 
compatible with the temperature and salinity of the formation was made, and in 2017 a workover and a Single Well Chemilcal Tracer 
Test (SWCTT) were carried out with very good results, obtaining almost 50% of reduction of residual saturation. Pilot implementations 
are been studied. Prior to the identification of a tertiary recovery pilot, another SWCTT has been planned in another well in Vizcacheras 
Block and another one in La Ventana Block. 

5. Llancanelo block: 

During 2017 there was no drilling activity, due to negotiations with new partner, which will continue in 2018. As a remarkable 
fact, a bottom heater was installed in one well with the objective of increasing production by improving the mobility of the heavy crude 
oil. The initial results regarding the operation of the tool were as expected. Currently the well is in evaluation regarding its productivity. 

6. Cerro Fortunoso block: 

Since 2016, the new water treatment plant has been in operation, which allowed the expansion of the secondary recovery project 

in the Northeast Block. The very good Secondary response obtained meant that during the year 2017 an expansion was made to the 
Central East North zone. In the two zones (Northeast Zone and Central East Zone), 16 wells were drilled, with results over expectations. 
The expansion of the secondary to the entire field will be completed with the drilling of new wells (between producers and injectors) 
and the repair of another wells. This activity will be carried out during the upcoming years. 

7. Valle del Río Grande Block: 

After visualizing a development opportunity for the Grupo Neuquén Formation at the Malal del Medio field, two wells were 
drilled in 2017. The good results obtained, allowed for a reinterpretation that increased the mineralized area. During 2018 the activity 
will be focus on the delineation of this opportunity.

Desfiladero Bayo: The Secondary Optimization project started in 2016, which included workover injection wells, 
wellhead acids, the adequacy of the injection facilities (with the installation of a Water Injection Plant) in order to 
guarantee the Water quality required, allowed to recover the production of the field to the expected volumes. During 
2017 41 workovers were carried out. Additionally, a Polymer Injection Pilot Project (Tertiary Recovery) has been 
implemented in 2016, which included drilling of producing wells, workovers, and the construction and assembly of a 
polymer injection plant. The injection began in August 2016. As of the date of this annual report change in the vertical 
profile has been observed waiting for oil response. In the Desfiladero Bayo East area, six wells were drilled during 
2017: two injectors and four producers (two with results over expectations and the other two below expectations.) in 
order to expand the southern zone and optimize development. As of the date of this annual report a Polymer Injection 
Pilot is also being implemented. Drilling activity has been completed and the pilot is on secondary recovery base line. 
Polymer plant will be installed by the end of 2018. 

Puesto Molina: During 2017, the Secondary Optimization Project continued through the drilling of five producing 
wells, with good results, and two water injector wells. Additionally, an opportunity was visualized to identify a 
mineralized zone in the eastern flank where there is no production, which would allow the drilling of new wells during 
the upcoming years. As of the date of this anual report , the first advanced well of this project was drilled. The well is 
producing a high percentage of water. If current flows are maintained, the project will be re-evaluated.. 

9. Chachahuén Sur Block: 

During 2017 the drilling activity in the block continued with the drilling of 124 wells (102 development producers, one horizontal 

producer, seven advanced wells, five extension wells and 9 water injectors), in order to complete the development of productive 
formations Rayoso Clástico Cycles 1a, 2a and 3a. The results were as expected. The secondary recovery project for Cycle 2a and Cycle 
3a is also under execution, where response is already observed. The results were as expected. New wells will be drilled in the next 
years.

During 2017, Chubut-Tierra del Fuego Region production was 49 mboe/d, representing 9% of YPF’s total production. 

Operated Areas—Development activities 

• Chubut concession: 

During 2017 the activities in Chubut Province oilfields were affected by the occurrence of two severe climatic events that led to 
significant production losses and also delays in the development execution programs. 

In March 2017, an unprecedented rainstorm occurred in the city of Comodoro Rivadavia and surrounding areas, declaring government 
of the province of Chubut a disaster zone. In June of 2017, a large-scale snow storm occurred, also declared by the government of the 
province of Chubut climatic emergency. 

That was the reason for which the production decreases as it was detailed previously. 

In order to recover production losses additional development plans were launched. In November 2017 the daily production reach the 
targeted values, and the delay in the execution of the drilling and workover activity was recovered. 

1. Manantiales Behr block: 

Despite the climatic issues, the gas production increased 3,3% in 2017 compared to 2016, due to the optimization of gas exploitation, 
with the adaptation and expansion of the facilities. 

48 wells were drilled in 2017. 24 of those wells reached expected results, and 24 resulted below expectations. The 24 that did not reach 
expectations were recently finished and are still under production optimization. 

The workover activity carried out gave positive results in all the fields except in La Carolina. 

The assisted recovery project in Grimbeek began in 2013 with a focus on standard water-flooding. The field was divided in three main 
areas (GbkII, GbkN and GbkNII). 

GBKII field is currently in an advanced stage of development with results, over expectations. On the other hand, activity in the GBKN / 
GNKNII fields is in the initial stage. 

Also, the construction of the facilities for the assisted recovery project in Grimbeek, has already begun and will be completed by 2019. 

During 2017, progress was made with the conceptualization of the second stage of the polymer injection development in GBKII, 
foreseeing the installation of new modular plants for the injection of polymers in 2018 and 2019. 

A third stage of development is being evaluated for the subsequent years. 

67 

The short-term focus on the Manantiales Behr block is to extend water-flooding projects along the field (GbkN full area and GbkNII) in 
order to sustain production growth. 

Throughout 2017 progress was made with the construction of water flooding facilities and conversion of wells to extend the secondary 
recovery area in La Carolina field where low reservoir pressure affects results in primary production new wells and workovers.. 

2. El Trébol – Escalante block: 

8 wells were drilled in the deepest reservoirs related to structural and stratigraphic traps with positive results. One of them, is an 
advanced well, that will allow the development of a new zone. 

The Workover activity also gave positive results 

3. Zona Central – Cañadón Perdido block: 

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. 

4. Restinga Alí block: 

Located on the coast between the urban area and the sea, development in this block was reactivated in 2013. 

Despite the climatic issues, oil production increased 4,3 % in 2017 compared to 2016, due to the construction of facilities (oil 
pipelines), allowing production optimization. 

Two wells were drilled in 2017. The first was an oil well with positive results, and the other a gas well that is under study, due to lower 
than expected production results.

Tierra del Fuego concession: 

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 have completed 6 
wells during 2017, with 3 wells reaching expected results, and 3 wells under evaluation due to lower than expected production results, 
where fracking and flow back programs are being analyzed in order to improve productivity. Additionally, source rock “Pampa Rincon” 
is present in these wells so studies are performed to define workover activity in Lago Fuego. 

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. 

In the Uribe block, 2 exploration wells were drilled targeting Springhill formation and the exploration of Tobífera series and 
unconventional resources. 2 core samples were taken during both drills; whose analysis, allows to focus future activity in the sector of 
the block with the best petro physical characteristics. Completion of the two wells are pending, and will be executed in 2018.

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 decreased from 12.196% to 7.196% since 2019. 

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

In 2017 a new agreement was signed with Chubut Province, in which it was established the future compliance scheme of the pending 
investments, under the Agreement for the implementation of an activity commitment and investment in hydrocarbon areas of Chubut 
Province. It is planned to drill 10 wells during 2018.

Santa Cruz Region 

During 2017, Santa Cruz Region production was 81.6 mboe/d, representing 15% of YPF’s total production. 

During 2017, our development activities in Argentina were mainly focused on the following regions and blocks: 

Operated Areas—Development activities 

During 2017, we implemented 18 integral development projects across six major development areas in the province of Santa 
Cruz (Cañadon de la Escondida, Las Heras, El Guadal, Los Perales, Cañadon Yatel and Cañadon Seco), comprising a total 
portfolio of 22 projects. The main projects include the following reserve areas: Cañadón Escondida, Las Heras, Cerro 
Grande, Seco León, Los Perales, Cañadon Yatel and El Guadal. 14 wells were drilled (13 development wells and 1 
exploration well) meeting expectations in the Cañadon Seco, Cañadon Yatel and Los Perales blocks and 348 workovers and 
associated facilities were executed focusing our strategy mainly on conversions and repairs of water injectors, which allow 
us to sustain our secondary production. 

The main objectives of these integral projects are: 

• Comprehensively developing the areas through the drilling of new wells and deep formations with gas 

objectives. 

• Acquiring the necessary information with electrical logs, rotated plugs and well testing. 

•

•

•

•

Increasing the recovery factor with new enhanced oil recovery projects. 

Increasing water injection to improve sweep efficiency. 

Extending horizontal and vertical limits with new appraisal and exploration wells. 

Providing development support through appropriate surface facilities. 

In the fourth quarter of 2017, we started an additional and challenging cost optimization plan, which as of the date of this annual report 
has progressed significantly, achieving results as expected. 

6. Cañadón Seco 

During 2017, 7 wells were drilled and 83 workovers were executed, with positive results. The drilling activity was concentrated in the 
Mina El Carmen formation, and 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) continues to be 
delineated. During 2018 we plan to take samples of rock and fluids in order to characterize better the D129 Formation and decrease the 
risk of the area, to be able to propose a development plan in the medium term. From the point of view of improved recovery, the 
objective 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. 

70 

7. Barranca Baya 

During 2017, 88 workovers were executed with results as expected. All the models that supported the drilling activity in previous years 
were based on 2D models. During 2017, 3D models were started to increase the original oil in situ, but the economic nature of the 
projects is being analyzed based on the price of crude oil. 

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. 

8. Las Heras 

During 2017, 32 workovers were executed with results as expected. 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. 

9. Lomas del Cuy 

During 2017, 29 workovers were executed. Secondary recovery was concentrated in Cerro Doce Grande Oeste, El Guadal Batería 2, 
Lomas del Cuy Norte and La Chitita Este blocks, implementing new projects and expanding existing projects.. We continued our 
improvements in water quality. 

Although in 2016 deeper drilling had been carried out in El Guadal Sur with the objective of Castillo and D129 geological formations, 
due to the economic conditions of 2017, it was decided not to continue with this activity. We plan to continue with the study of the 
block during 2018, to propose some horizontal well during 2019 with objective of D129 formation. 

10. Los Perales—Las Mesetas 

During 2017, 2 wells (including one replacement injector and one producing well of polymer project) and 78 workovers were drilled, 
with results as expected. There are several expectations with this polymer project and this well is aimed at gas. 

Secondary activity is present in all blocks; however 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 aeral point of view, incorporating new 
layers and completing existing meshes. 

The first pilot of polymer injection was started in the Santa Cruz regional, in Los Perales Central B III block at December 2017. 

11. Cañadón Yatel 

During 2017, 5 wells and 38 workovers were drilled with positive results. Drilling activity was concentrated at the Estancia Cholita 
reservoir. An oil reservoir under the gas cap of the D-129 formation began to be developed in the southern and central blocks. The 
electrification of the block began in 2016, and continued during 2017 allowing us to exploit the wells with greater reliability and 
minimize mechanical problems. We plan to continue such activities during 2018.

4. Non-Operated Areas—Development Activities: 

12. 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 start up originally 
expected in 2017 and then postponed to March 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 estimated 
value of the project is approximately U.S.$387 million. 

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 fulfill commitments are planned to begin early 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.

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 2 years, starting on December 2017. 

3.

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.

Downstream 

During 2017, 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 2017, the Downstream segment was organized into the following divisions: 

• Refining Division (oil refining and petrochemical production); 

• Domestic Marketing and Chemicals Division (commercialization of refined and petrochemical products obtained from such 

processes); and 

•

Logistic and Trading Division (logistics related to the transportation of oil and gas to refineries and the transportation and 
distribution of refined and petrochemical products to be marketed in the different sales Channels). 

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 2017, our crude oil production was substantially 
destined to our refineries, represented approximately 78.6 % of the total crude oil processed by our refineries, while in 2016 it was 
85.7%. 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

During 2017, our global refinery utilization reached 91.73%, compared to 91.87% in 2016, 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 189,000 bbl/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 2017, the refinery processed 
approximately 172.3 mbbl/d. The capacity utilization rate at the La Plata refinery for 2017 was 91.15 % compared with 165.5 mbbl/d 
processed in 2016, with a utilization rate of 87.6 %. The crude oil processed at the La Plata refinery, 77.96 % of which was 
YPF-produced in 2017, 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 105,500 bbl/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 2017, the refinery processed approximately 98.0 mbbl/d, with a capacity utilization rate of 
more than 92.9%. In 2016, the refinery processed 106.0 mbbl/d, with a capacity utilization rate of more than 100%. The lower capacity 
utilization during 2017 was due to planned maintenance shut-downs of the topping, isomerization, gasoil hydrotreating and coking units 
from June to July. 

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 77.5% of the crude oil processed at the Luján de Cuyo refinery in 2017 (and 
77.8% of the crude oil processed in this refinery in 2016) 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 25,000 bbl/d. During 2017, the refinery 
processed approximately 22.8 mbbl/d, with a capacity utilization rate of 91.2%, compared with 22.0 mbbl/d processed in 2016 with a 
capacity utilization rate of 88.1%. 

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 2017, 100% of the refinery’s crude supplies (and 98.2% of the crude oil 
processed in this refinery in 2016) were produced by us. 

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 37/2016) and diesel requires a 10% blend of FAME (resolution 1125/2013), the same blend request of 2016 
and 2015, except from gasoline which blend requirement was 10% in 2015. 

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.

Marketing Division 

Our Marketing Division supplies gasoline, diesel, LPG and other petroleum products throughout Argentina and other countries in the 
region. We supply several industries, including retail, transport and agriculture. 

During 2017, YPF maintained its leading position in Argentina, reaching a market share of 56.1% for liquefied fuels. 

YPF sells two types of gasoline: Infinia, a premium 98 octane gasoline, and Super, a regular 95 octane gasoline. 

Our market share of Infinia and Super gasolines, according to our estimates, was 61.3 % and 52.4%, respectively, as of December 31, 
2017, compared with 60.7% and 52.8%, respectively, as of December 31, 2016. Our sales volume for Infinia was 1,774 mcm in 2017 
(20.1% higher than in 2016) and 3,344 mcm for Super in 2017 (2.1% less than in 2016). 

With respect to diesel, according to our own estimates, our market share of diesel (500 and 1500 ppm) and Infinia diesel (10 ppm) was 
56.5% and 57.6 %, respectively, as of December 31, 2017, compared with 55.7% and 58.1%, respectively, as of December 31, 2016. 
Along with Infinia diesel (10 ppm), for which sales volume was 1,750 mcm in 2017 compared to 1,372 mcm in 2016, our diesel (500 
and 1500 ppm) decreased a sales volume of 5,947 mcm compared to 6,239 mcm in 2016. Finally, sales volume of Infinia diesel reached 
22.7% of total diesel sales volumes, up from 18% in 2016. 

During 2017, the competition was fiercer in the domestic Argentine market than in previous years, with our competitors implementing 
several aggressive marketing activities. Due to new market conditions for fuels in Argentina (see “Item 5. Operating and Financial 
Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions”), we expect that this competition will 
continue, challenging us to respond with effective marketing and promotional tools. Consequently, during 2017 we worked on regional 
promotions based on the needs of each market. Micro-marketing kits have been created in order to maintain and increment sales in 
markets that have become competitive due to new competitor operations, such us promotion “Promo Rally” in Cordoba, “Double KM 
Serviclub”, “Tall Cafee” in our YPF Full stores, “YPF Collections Competitions Cars”, among others. 

We continue with certain promotions based on the Serviclub loyalty program which allowed us to improve sales of Infinia gasoline and 
diesel and increase the base of members of the program. As of December 31, 2017 the loyalty Serviclub program has more than 2.6 
millon members (67% higher than 2016). 

The communication and relationship actions carried out during 2017 have been focused on our Premium fuels in order to maintain the 
perceived quality of our premium products. 

In November 2016, YPF launched Infinia diesel, a new premium diesel with a new formulation. The release plan involved an ambitious 
campaign in mass media and at sales points, and strong internal training of our salesforce. The launch of this product is aligned with the 
projected migration of heavy duty vehicles fleets to Euro 5 and 6 technology (regulatory command) in the coming years and, to a lesser 
extent, to capture particular premium customers. 

YPF markets lubricants through three segments of the domestic market: retail, agriculture and industry. Our three manufacturing 
facilities, part of the La Plata industrial complex, include lubricant, asphalt and paraffin production lines. Our line of automotive 
lubricants, including mono-grade, multi-grade and oil, 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. 

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. 

YPF also markets lubricants in Brazil and Chile, where we have subsidiary companies. Additionally, through a network of exclusive 
resellers, we market lubricants in three bordering countries (Uruguay, Paraguay and Bolivia). 

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

a) Retail Division 

As of December 31, 2017, the Retail Division’s sales network in Argentina consisted of 1,563 retail service stations, compared to 1,547 
as of December 31, 2016. Of these, 113 are owned by YPF. The remaining 1,450 service stations are associated service stations. 
OPESSA, our wholly-owned subsidiary, actively operates 172 retail service stations, of which 88 are owned by YPF, 26 are leased to 

the Automóvil Club Argentino and 58 are leased to independent owners. Additionally, YPF owns 50% of Refinor, a company operating 
66 service stations. 

76 

According to our estimates, as of December 31, 2017, we were the main fuel retailer in Argentina, with 35.3% of the country’s gasoline 
service stations, followed by Shell, Axion, Oil and Petrobras and with 14.2%, 11.8%, 6.3% and 6.0%, respectively. During 2017, our 
market share in diesel and gasoline, marketed in all segments, increased from 55.6% to 56.1%, from December 31, 2016 to 
December 31, 2017. 

Our convenience stores, YPF Full and YPF Full Express, are present in 435 and 107 points of sale, respectively, as of December 31, 
2017. Additionally, a modern oil change service shop called YPF Boxes is present in 283 service stations across the country. 

We highlight the opening of 35 new service stations in our network during 2017. This marks a milestone in the development of the YPF 
retail service station network in recent years because of its relevance in investment, sales volume and the full national coverage, as the 
openings were made in 14 of the 23 provinces of Argentina. 

We became the first retailer in the Argentinian market to implement ATMs (automatic teller machines), reaching an amount of 15 
machines working in service station owned by YPF. The cash in the machines comes from the service station operation, optimizing the 
operative process of cash recollection. 

With the purpose of providing technological solutions to contribute the competitiveness of our network, we began the Intelligent 
Operation Control (CIO) project. This new solution replaces the actual system that links YPF to the service station. It allows a superior 
transactional processing of our clients information, with an on-line visualization of each individual operation. As of December 31, 2017, 
the project was implemented in 125 service stations and we plan to finish the system implementation during the first half of 2019. 

With the commitment to streamline payment processes at service stations and continue to improve our consumer’s experience, we 
recently launched two virtual payment methods (QR payment method and “Serviclub PASS”). 

In July 2017, we renew the AUBASA service stations on the Buenos Aires—La Plata highway, becoming the largest service area in the 
country. 

b) Agriculture Division 

The Agriculture Division provides an extensive portfolio of products and services to agricultural producers, including agricultural 
advice, and delivery and application of products at the consumption site, under a unified brand image, directly or through a network of 
104 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 2017, YPF launched 9 new products (phytosanitaries, fertilizers and 
adjuvants), under the YPF brand. Additionally, through distribution agreements with leading local and international suppliers, the 
product palette has been extended to 29 more completing an offer of 120 different agro products. This year our market share of 
fertilizers, according to our estimate, was 9.6% compare to 8.7% (2016). 

YPF developed crop financing with instruments such as credit cards with local banks, for more than U.S. $ 100 million. YPF accepts 
different types of grains as payment (canje), mainly soybean, but also corn, rice, wheat, sorghum, sunflower, barley and blueberries. 
Some of 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 7% of YPF’s refinery needs. During 2017, we received approximately 1.5 million tons of grains (a 27% increase 
compared to 1.2 million tons in 2016), primarily soybeans, that positions YPF among the top five exchangers in Argentina. As 
December 31, 2017 the revenue from these exports represented approximately U.S. $ 371.6 million, a 9.2% increase compared with 
2016. It is worth noting that in 2017 YPF is the tenth exporter in the argentine market of soybean meal and also is the tenth exporter in 
the argentine market of soybean oil. 

c) Industry Division 

This division supplies the entire national industry and transportation (ground and air) sectors, which require a broad portfolio of 
products and services that meet the needs of the customers. The division develops specific solutions for the mining, oil & gas, aviation, 
transport, infrastructure and construction sectors. We supply products such as fuels (diesel, gasoline, fuel oil, Jet A-1), 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 11 industrial 
distributors with national coverage. 

77 

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 2017 we implemented 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, in 2017 we completed long term agreements with main argentine railway companies to supply diesel, gasoline, 
lubricants and services. 

Another highlight of the year 2017 in the transportation segment was the steady growth of sales through the YER (YPF en ruta) fleet 
card, which resulted in an increase of 36% of volume sales than 2016, mainly as a result of certain incentive programs that were 
launched. This card is designed to cover the supply and administration needs of vehicles of cargo and passengers. 

Regarding to the aviation segment, low cost airlines have recently entered the Argentine market. Consequently, during 2017 the 
company completed agreements for the supply of JET A1 with two low-cost companies which recently started to operate in Argentina. 
We expect this market to increase in the future. 

In addition, we have become the second oil company in Santiago de Chile’s airport, reaching 21.5% of market share. 

In the mining segment, in 2017 we closed a long term agreement for the supply of diesel and gasoline (1.000 m3 per month) and we 
implemented an operation “in house” in Cerro Moro mining project. This operation includes the administration, maintenance and 
operation of the fuel plant. Besides, we closed an agreement with another mining company for 2 years for the supply of diesel and 
gasoline (1.600 m3/month). 

In the asphalt segment, during 2017 we reached asphalt sales record of 313 ktn, double the previous year, reaching a market share of 
45% (approximately 11 points of market share higher compared to 2016). 

d) Lubricants and Specialties Division 

In our industrial complex located in the city of La Plata, lubricants, asphalts, paraffin and Blue 32 are produced. In 2017, the necessary 
investments were made to ensure the supply of market demands, highlighting the start-up of the Blue 32 plant and the expansion of 
production capacity of modified asphalts according to the latest trends in the road construction industry. Blue 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). 

During 2017, our sales of lubricants increased by 2.4% with respect to 2016. Sales to the domestic market grew by 2%, and sales to the 
external market increased by 5%. 

Exports are made to two large groups. On the one hand, we sale to our wholly-owned companies in the main markets of Brazil and 
Chile, where the volume sold decreased by 39% in Brazil with respect 2016 due to the increase in local production and increased 3% in 
Chile with respect to the previous year. On the other hand, we export to our network of distributors located in Bolivia, Uruguay, 
Paraguay and Ecuador, where the volume of sales were 18% higher than 2016. 

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 market in high-end lubricants. Our market share as of December 31, 2017 was 39.5% (an increase of 
1.4% compared to 2016) according to information provided by the Ministry of Energy. The critical factors of competitiveness are the 
usage and referral agreements from the main OEMs (Ford, Volkswagen, 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 14.1 
Km3 in 2017, an increase of 0.8% compared to 2016. With respect to our heavy duty motor oil (HDMO) line (Extravida), 2017 sales 
decreased by 1.8%.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). 

78 

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. 

e) LPG Division 

Through our LPG Division, we sell LPG to the foreign market, the domestic wholesale market and to distributors that supply the 
domestic retail market. The LPG Division does not directly supply the retail market. It is supplied by YPF Gas S.A., which is our 
affiliate. 

During 2017, 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 2017 reaching approximately 580 mtn, compared with 574 mtn in 2016. Of 
this, approximately 402 mtn were sold in the domestic market, compared to 410 mtn in 2016. 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 2017 reached approximately 176 mtn, compared to 164 mtn in 2016. The main destinations were Chile, 
Paraguay and Bolivia. 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. 3,512 million and Ps. 2,096 million in 2017 and 2016, 
respectively. 

The LPG Division obtains LPG from natural gas processing plants and from our refineries and petrochemical plants. We produced 541

(1) The San Sebastian plant is a joint venture in which we own a 30% interest; El Portón is 100% owned by us; General Cerri belongs 

to a third party with which we have a processing agreement. 

(2) This production does not include LPG used as petrochemical feedstock (olefins derivatives, polybutenes and maleic). 
(3) Purchased from Refinor. We also have a 50% interest in Refinor, which produced 179.4 mtn of LPG in 2017. 

Regarding to sales prices, the butane local market is regulated by the government, where the local prices have been unmodified since 
April 2015 until 2017. In April (resolution 56-E / 2017) and December 2017 (resolution 287-E / 2017) the government updated 
Butano’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 Ministry of Energy are referred to export parity.

Chemicals Division 

Petrochemicals are produced at our petrochemical facilities in Ensenada and Plaza Huincul. Additionally, we also own a 50% interest in 
Profertil, a company that has a petrochemical complex in Bahía Blanca, as discussed below. 

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. 

The main petrochemical products and production capacities per year are as follows:

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 2017 we successfully installed a new gas flare in our methanol plant in the Plaza Huincul refinery and a maleic anhydride pastillator 
in the CIE. 

Additionally, in accordance with our midterm commercial strategy of stablishing YPF as one of the main players of the Southern 
Cone’s petrochemical industry, in 2017 we managed to sell over 87,000 tons of our solvents and specialties product lines to the 
Southern Cone region, 18% higher than 2016 and the highest sales to that destination in the last five years. 

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

In 2017, 2016 and 2015, 84%, 80% and 72%, 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. 

We also participate in the fertilizer business, directly and through Profertil, a 50%-owned subsidiary. Profertil is a joint venture with 
Agrium, 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. 

The CIE was certified under ISO 9001 in 1996 and recertified in 2013 (2008 version). The La Plata petrochemical plant was certified 
under ISO 14001 in 2001 and recertified in 2014 (2008 version). The plant was also certified under OHSAS 18001 in 2005 and 
recertified in 2014. Since 2008, the plant verified the inventory of CO2 emissions under ISO 14064: 1 and, in 2011, inventories of CH4 
and N2O emissions were verified as well. The CIE laboratory was certified under ISO 17025, in 2005 and recertified in 2013. 

The CIE has recently attained ISO 50001 certification (2011 version) in November 2015, covering the following processes: production 
of complex aromatics, olefins, maleic, polybutenes and the energy generation facilities that operate within the La Plata petrochemical 
complex. 

The methanol plant was certified under ISO 9001 in December 2001 and recently recertified with ISO 9001 (2015 version) in July 
2016. The methanol plant was also certified under ISO 14001 in July 1998 together with the Plaza Huincul refinery, and recertified in 
July 2016 with ISO 14001:2015. In addition, the plant was also certified under OHSAS 18001 in December 2008, and the last date of 
recertification was August 2014.

• management and development of our petrochemical business, planning and economic and commercial control, marketing 

and post-sale service of petrochemical products. 

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 transandean 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 53 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.

YPF currently blends ethanol in the Luján de Cuyo, Monte Cristo, San Lorenzo, La Plata, Junín, Plaza Huincul, Barranqueras, 

Concepción del Uruguay, Villa Mercedes and La Matanza storage plants. 

In 1998, our logistics activities were certified under ISO 9001 (quality performance) and ISO 14001 (environmental performance), 
and recertified in 2012 under ISO 9001:2008 and ISO 14001:2004. In 2010, logistics activities were also certified under OHSAS 18001 
(security performance) and recertified in 2013. In 2014, our trucking activities were certified under ISO 39001 (road traffic safety 
management system). 

Our logistics activities were recertified in 2015 under ISO 9001 and ISO 14001, and recertified in 2016 under OHSAS 18001. 
Additionally, in 2016, our land transport and light vehicle logistics activities were certified under ISO 39001:2012. As of December 31, 
2017, our logistics processes remain certified under ISO 9001, ISO 14001, OHSAS 18001, and ISO 39001 Standards. 

Trading Division 

Our Trading Division sells refined products and crude oil to international customers and crude oil to domestic oil companies. 
Exports may include crude oil, unleaded gasoline, diesel, fuel oil, LPG, light naphtha, virgin naphtha, MTBE, green coke and decanted 
oil. 

This division exports to different countries, principally to United States of America and Brazil, as well as to other countries. Sales 

to international customers for 2017 and 2016 were Ps. 4,982 million and Ps. 3,305 million, respectively. In 2017, refined products 
accounted for 49% of total sales, up from 37% in 2016. In 2017, 48% of total sales corresponded to marine fuels, down from 59% in 
2016. In 2017 and 2016, sales volumes to customers outside Argentina consisted of 3.0 mmbbl and 2.4 mmbbl of refined products, 
respectively, and 2.3 mmbbl and 2.7 mmbbl of marine fuels, respectively. 

For the domestic market, sales of crude oil totaled Ps. 995 million, or 1.2 mmbbl, in 2017 and Ps. 784 million, or 0.9 mmbbl, in 

2016. Sales of marine fuels totaled Ps. 1,726 million, or 1.2 mmbbl, in 2017 and Ps. 1,652 million, or 1.3 mmbbl in 2016. 

In addition, imports of low sulfur diesel, gasoline, AVGAS and JP1 in 2017 totaled 4.6 mmbbl, a decrease of 18% compared with 

5.6 mmbbl in 2016. Imports of fertilizers, agrochemicals and paraffin totaled 0.16 million tons in 2017, a decrease of 16% compared 
with 0.20 million tons in 2016. China and Morocco were the principal origin of these imports. 

In 2017, imports of crude oil totaled 1.4 mmbbl. All of them came from Nigeria. 

Gas and Power 

During 2017, 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 and Escobar terminals, through the contracting of two regasification 
vessels; and (iii) the generation of both conventional thermal electricity and renewable energy projects. 

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, 2017, we were not contractually committed to deliver material quantities of crude 
oil to third parties in the future. 

As of December 31, 2017, we were contractually committed to deliver 13,511 mmcm (or 477 bcf) of natural gas in the future, (without 
considering interruptible export supply contracts) of which approximately 10,153 mmcm (or 359 bcf) will have to be delivered from 
2018 through 2020. According to our estimates as of December 31, 2017, our contractual delivery commitments for the next three years 
could be met with our own production and, if necessary, with purchases from third parties. In addition, in regard with The Terms and 
Conditions (See “Item 4. Information on the Company—Legal and Regulatory Framework and Relationship with the Argentine 
Government—Market Regulation—Natural gas”), during January 2018, we signed agreements with natural gas distribution companies 
compromising to deliver 4,755.9 mmcm (or 167.9 bcf) of natural gas in 2018. 

82 

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. 

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 araising 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 for the Provision of Natural Gas to Gas Distributors through Networks “(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 US 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 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 N ° 508-E / 2017 Resolution 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—Regulatory Framework and Relationship with the Argentine Government—Natural Gas.” 

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 

83 

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 E&P. 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 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 fulfilled the volumes mentioned in the 
addendum. 

We are currently 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). This contract has been modified to an interruptible contract. 

We have a 21-year contract (entered into in 1999) to deliver 93 mmcf/d (or 2.63 mmcm/d) of natural gas to a Chilean distribution 
company (Innergy) 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). 

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 “—The Argentine natural gas market” and “Item 8. Financial Information—Legal Proceedings.” As a result of actions 
taken by the Argentine government, through measures described in greater detail under “—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. 

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 1,775 bcf (or 50.26 bcm) in 2017. We estimate that the number of users connected to distribution 
systems throughout Argentina was approximately 8.7 million as of October 31, 2017. 

In 2017, we sold approximately 35% of our natural gas to local residential distribution companies, approximately 1.5% to 
compressed natural gas end users, approximately 55.9% to industrial users (including our affiliates, Mega and Profertil) and power 
plants and 7.2% to YPF downstream operations. Sales were affected by increased consumption by residential consumers during winter 
months (June to August). During 2017, approximately 87.6% of our natural gas sales were produced in the Neuquina basin. In 2017, 
our domestic natural gas sales volumes were approximately equal to 2016. 

During the past few years, the Argentine government has taken a number of 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 “—Delivery 
commitments—Natural gas supply contracts.” Argentine producers such as YPF complied with the Argentine government’s directions 
to curtail exports in order 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. 

84 

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—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—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 79% as of December 31, 2017) 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 ENARSA under certain agreements since May 2008. As of the date of this annual 

report, both parties are engaged in renegotiations towards an extension of the agreement, which expires in October 2018 

Since the beginning of its operations, this regasification vessel has converted 21.85 bcm (or 771,6 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 2017, natural gas injected into the network amounted to approximately 2.21 bcm (or 78.2 bcf). 

YPF is the operator of UTE Escobar (a joint venture formed by YPF and ENARSA), which operates an LNG Regasification 

Terminal (“LNG Escobar”) located in the km 74.5 of the Paraná River. The LNG Escobar terminal has a floating storage and 
regasification unit permanently moored at a new port facilities, for which UTE Escobar has executed agreements with Excelerate 
Energy to provide and operate a 151,000 cm (or 533,252 cf) regasification vessel moored at the LNG Escobar terminal with the 
capacity to supply up to 20 mmcm/d (or 700 mmscf/d) of natural gas. 

Since the beginning of its operations, this regasification vessel has converted 16.50 bcm (or 582.6 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 2017, natural gas injected into the network amounted to approximately 2.23 bcm (or 78.7 bcf). 

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. 

85 

Other investments and activities 

NGLs 

We participated in the development of our affiliate Mega to increase its ability to separate liquid petroleum products from natural 
gas. Through the fractionation of gas liquids, Mega increased production at the Loma La Lata gas field by approximately 5.0 mmcm/d 
(or 176.5 mmcf/d) in 2001 with our assistance. 

We own 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 located 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 in close proximity to the fractionation plant. 

Mega’s maximum annual production capacity is 1.62 million tons of natural gasoline, LPG and ethane. YPF is Mega’s only 

supplier of natural gas. The production of the fractionation plant is used mainly in the petrochemical operations of PBBPolisur S.A. 
(“PBB”), owned by Dow Chemical Company, and is also exported by tanker to Petrobras’ facilities in Brazil. 

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, on a monthly basis, a fee of Ps. 0.405 per cubic meter of natural gas it purchases. This requirement has a 
significant impact on the operations of Mega and has been challenged in the Argentine federal courts. On October 27, 2015, the 
Argentine Supreme Court (“CSJN”) 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 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, which, as of the date hereof, has not been ruled on by the first instance judge. 

Finally, on April 1, 2016, MINEM 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. 

Electricity market—generation 

The Argentine Electricity Market 

Argentina’s energy demand in 2017 was almost similar to its energy demand in 2016, according to Compañía Administradora del 
Mercado Mayorista Eléctrico S.A. (“CAMMESA”). During 2017, domestic consumption decreased 2.14% and exports decreased more 
than 79%. 

In order to satisfy this energy demand, Argentina’s overall power generation in 2017 was similar to its power generation in 2016, 
according to CAMMESA. In 2017, 64,5% of Argentina’s power generation came from thermal power plants, 28.9% from hydroelectric 
power plants, 4.2% from nuclear power plants, 1.9% from renewable energy sources and 0.5% from spot imports from Uruguay, Brazil, 
Paraguay and Chile (733.8 Gwh). Those spot imports were used to satisfy peak demand hours without capacity reserves. 

Peak capacity demand reached its maximum in February 2017 (25,628 Mw), but maintaining1,614 Mw of capacity reserve for 

security of the electrical system. 

Thermal power plants consumed 1,396,122 cm of diesel oil, a decrease of 41.4% compared to 2016, 1.286 million tons of fuel oil, 

a 51.5% decrease compared to 2016, and 17.08 billion cm of natural gas, an 9.8% increase compared to 2016. 

The average electricity price was Ps. 1157.1/MWh, a 9.7% increase compared to 2016, while the annual average marginal cost of 
production was Ps. 1,473/MWh, also a 28.8% decrease compared to 2016 due to an improvement in the efficiency of power plants and 
to a lower consumption of liquid fuels. 

86 

In 2017, Resolution No. 19/2017 of the Secretariat of Electric Energy replaced Resolution 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. 

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. 

YPF in Power Generation 

On August 1, 2013, as a result 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 2017, YPF EE participated in the following power generation plants with an aggregate net installed capacity of 1,367 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 100% interest; and 

a 100% interest in Loma Campana Este (14 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 100% interest; 

a 66,67% interest in Loma Campana II (107 MW gas turbine) through YGEN, in which we have 66,67% interest; and 

a 40% 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 42.86% 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 located in the Los Perales natural gas field; 

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

•

Plaza Huincul Power Plant (40 MW). 

In 2017, YPF EE generated 5,270 GWh with its two combined cycle plants. Central Térmica Tucuman’s production was 2,498 
GWh, and Central Térmica San Miguel de Tucumán’s production was 2,772 Gwh. Additionally, Central Dock Sud generated 4,944 
GWh. The energy produced by YPF EE and Central Dock Sud (10,214 GWh in total) represented 7.45% of Argentina’s electricity 
generation in 2017. 

Energy produced by both combined cycle plants in Tucumán was 5% lower in 2017 compared to 2016, because of major 

overhauls on units TUCUTV01 and TUCUTG02 at Central Térmica Tucumán in September 2017 and October 2017. 

Energy produced by Central Dock Sud in 2017 decreased by 1.62% for annual borscopy inspection on units DSUDTG10 and 

DSUDTG09. 

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 located in Añelo, Neuquén. This additional generation plant was 
designed with the objective of supplying YPF’s internal energy demand all over the country. 

87 

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. 

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 
the January 27, 2018. 

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. 

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, 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 is expected to be finished by 2018 with the 
generation of 99 MW. 

In addition, and in the context of the 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 100 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 by January 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). Besides, in January, 2018 YPF EE bought the cogeneration plant in La Plata to Central Puerto S.A 
(128 MW). 

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. 

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 GEEFS 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 establishes the conditions for the 
capitalization of YPF EE (the “Share Subscription Agreement”). The Share Subscription Agreement establishes that GE, subject to 
compliance with certain preceding conditions, will subscribe for shares of YPF EE in order to have a shareholding of 24.99% of its 
capital stock and jointly control this company with YPF. 

The contribution will be US$ 310 million, composed as follows: 

•

Subscription price of US $ 275 million: 

•

•

US $135 million as of 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 prices of Resolution 19/17 

(33.33% as of 24 months from the closing date of the transaction and 16.67% each subsequent year). 

88 

On March 20, 2018, 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.), subscribed for shares of YPF Energía Eléctrica S.A. (“YPF EE”) in an amount equal 
to 24.99% of YPF EE’s capital stock through a cash contribution of US$ 275,000,000, plus a contingent payment for up to 
US$35,000,000. 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 S.A. have joint control of YPF EE. 

Additionally, YPF continues negotiating with a possible third partner for the purposes of granting an option to subscribe an additional 
24.5% of YPF EE’s capital stock, on similar terms as agreed with GE. 

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 2017, Metrogas distributed approximately 20.4 
mmcm (or 719.7 mmcf) of natural gas per day to 2.3 million customers in comparison to approximately 19.3 mmcm (or 681.0 mmcf) of 
natural gas per day to 2.4 million customers in 2016. 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. As of the date of this annual report, ENARGAS has not issued any decision regarding the 
appeal or the submitted tentative schedule. 

Such presentation does not imply withdrawal of the aforementioned appeal. 

On April 5, 2018, the Company was notified that the ENARGAS rejected the motion for reconsideration submitted by YPF on 
March 30, 2017. As of the date of this annual report, we are discussing the following legal steps as a result of the previously mentioned 
rejection. 

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—Regulatory Framework and Relationship with the Argentine Government— Public Emergency”. 

89 

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, see “Item 4. Information on the Company—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 Tecnología 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, to create 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 (quick wins). 

Y-TEC explores opportunities throughout the actual and future energy sector. This is a broad and diversified strategy approach that 
cover 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 66 projects, 35 short-term high impact quick wins and more than 100 technical assistance and 
specialized services. 

In 2017, U.S.$30.3 million was allocated to R&D activities, and U.S.$4.56 million (YPF’s working interest) was invested in new 
equipment. In 2016, U.S.$27.7 million was allocated to R&D activities, and U.S.$12.23 million (YPF’s working interest) was invested 
in new laboratory building and equipment. In 2015, U.S.$29.7 million was allocated to R&D activities, and U.S.$22.7 million (YPF’s 
working interest) was invested in a new laboratory building and equipment. 

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 technological products of high impact 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 the design, development and application of very 
specific technologies. Our most important challenges include the design and development of simulation and modeling tools; measuring 
and monitoring solutions; proppants and smart proppants; fluids, smart fluids, additives and chemical products for optimizing drilling, 
completion and production operations. 

To optimize production from mature fields, we focused on 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. 

90 

Regarding refining and marketing of petroleum products, 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 greater challenges. 

Supporting the process of transformation initiated by YPF and in line with the advancement of digital technologies, we created in 
Y-TEC first Center of Excellence in Analytics (COE) fully dedicated to run 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. For 2018, 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 multiply value, by prioritizing projects which 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, amending 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. 

In January 2017 the government adopted a policy of convergence between the domestic oil price and the international benchmark 
and since October 2017 has suspended the price-setting system for domestically-consumed fuel. Since then, the hydrocarbons market in 
Argentina had become a liberalized market and, thus, fluctuate. This decision formally ended the transition to international oil price 
parity and, consequently, it is expected that, from 2018 onwards, that petroleum companies in Argentina will establish their own pricing 
policies. See “Item 3. Key Information—Risk Factors—Risks Relating to the Argentine Oil and Gas Business and 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 the Argentine Oil and Gas Business and Our Business— We are exposed to the effects 
of fluctuations in the prices of oil, gas and oil products.” 

We continuously assess the external environment and our competitive position in order to adjust our business strategies and plans to 
create and sustain competive advantage. 

91 

Environmental Matters 

YPF-Argentine operations 

YPF is committed to operate in balance with its environment. In this sense, it 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. 

The approach is based on the Policy of Safety, Protection of the Environment and Preservation of Health, on 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. 

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 to comply with these laws and regulations. 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. 

We continued making investments in order to comply with new Argentine fuel specifications, pursuant to Resolution No. 1283/06 
(amended by Resolution No. 478/2009) of the Argentine Secretariat of Energy (currently as Argentine Ministry of Energy and Mines) 
(which replaces Resolution No. 398/03) relating to, among other things, the purity of diesels. In the La Plata refinery, a new ultra-low 
sulfur diesel desulfurization plant was started up during 2012. In Luján de Cuyo refinery, new HDS III (diesel desulfurization) and HTN 
II (gasoline desulfurization) plants were started up in 2013. Additionally, we are increasing the tankage capacity of several of our 
terminals in order to optimize fuel distribution logistics. First stage projects related to biofuels, such as the addition of bioethanol to 
gasoline and FAME to diesel, were accomplished by the end of 2009 and were operational by the beginning of 2010. During 2010 and 
2011, additional bioethanol facilities at several terminals were installed and became ready to operate. Also, during this period, further 
investments were made in several terminals in order to allow the increased addition of FAME to diesel and to improve the related 
biofuel logistics. A new facility for FAME blending was started up in 2013 in the Montecristo terminal. In 2014, a 3,000 cm FAME 
tank at Terminal Dock Sud (“TDS”) a 3,000 cm FAME tank at TVM and two 200 cm ethanol tanks at Concepción del Uruguay were 
built. A new 3,000 cm FAME tank was also completed in the San Lorenzo terminal. 

As in previous years, we continued with the initiatives relating to remedial investigations, feasibility studies and pollution abatement 
projects, which are designed to address potentially contaminated sites and air emissions. In addition, we have implemented an 
environmental management system to assist our efforts to collect and analyze environmental data in our upstream and downstream 
operations. 

Also, as part of our commitment to satisfying domestic demand for fuels and meeting high environmental standards, during 2013 we 
started up a new Continuous Catalyst Regeneration (“CCR”) unit. The plant uses the latest worldwide technology to perform chemical 
processes and improvements in productivity, safety and environmental standards. Additionally, the plant produces aromatics that can be 
used as octane enhancers for gasoline and automotive applications, as well as increases hydrogen production to feed the fuel 
hydrogenation processes to increase fuel quality and reduce sulfur content, further reducing the environmental impact of internal 
combustion engines. 

92 

On September 2016, we started up a new coke unit at the La Plata refinery, replacing the one that was severely damaged in the incident 
that occurred on April 2, 2013. The new unit design is expected to optimize energy efficiency and minimize particulate matter 
emissions. 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 1991, we entered into an agreement with certain other oil and gas companies to implement a plan to reduce and assess environmental 
damage resulting from oil spills in Argentine surface waters to reduce the environmental impact of potential oil spills offshore. This 
agreement involves consultation on technological matters and mutual assistance in the event of any oil spills in rivers or at sea due to 
accidents involving tankers or offshore exploration and production. 

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. 

With respect to climate change, YPF has: 

•

•

•

committed to active promotion of identification and pursuit of opportunities to reduce greenhouse gas emissions 
in our operations; 

a Company target has been set to reduce the intensity of CO2 emissions in future periods; 

established a new internal corporate commitment on climate change and energy efficiency which was developed 
in June 2015. This document sets the framework for the company to work on reducing greenhouse gas 
emissions, contributing to mitigation activities while promoting sustainable development and preserving natural 
resources. In October 2017, it was renewed together with the Company’s Sustainable Policy; 

intensified the execution of internal projects to obtain credits under the relevant clean development mechanisms 
through the efficient use of resources, contributing to the transfer of technology and to the sustainable 
development of Argentina; 

obtained the approval of the United Nations in December 2010 for an industrial project developed by YPF in 
Argentina defined as a Clean Development Mechanism (“CDM”) project, the first of its kind in the world. The 
project in the La Plata refinery reduces the emissions of greenhouse gases from fossil fuels used for process 
heating by replacing these fuels with recovered waste gases that were previously burned in flares. The project 
increases energy efficiency by reducing the demand for fuel oil and natural gas, allowing an estimated annual 
emission reduction of approximately 200,000 tons of CO2. On September 7, 2012, 89,930 Certified Emission 
Reductions (CERs) were issued by the United Nations after a peer review of the reported reduction in emissions. 
During 2017, La Plata project reduced CO2 emissions by approximately 119,200 tons; 

obtained the approval of the United Nations in December 2011 for an industrial project developed by YPF in 
Argentina defined as a CDM at the Luján de Cuyo refinery. During 2017, Luján de Cuyo project reduced CO2 
emissions by approximately 24,700 tons; 

developed a methodology which 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.” Six 
CDM projects are being developed around the world (Argentina, China, Kuwait and Egypt) applying this 
methodology developed by YPF;

•

undertook third-party greenhouse gas emission inventory verification for refining and chemical operations in 
accordance with the ISO 14064 Standard. The inventory at CIE has been verified since 2008. In July 2017, the 
inventory verification process for greenhouse gases in the La Plata complex and the Luján de Cuyo refinery was 
completed. During 2016, we began to implement third-party greenhouse gas emission inventory verification in 
the Plaza Huincul refinery, achieving its verification in 2017. Based on our estimations regarding the 
contribution that forestry projects located in the province of Neuquén had with respect to climate change we 
found that these projects constitute approximately 6,500 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 2013; 

• We continue working on the commitment to minimize gas sent to flares and gas vented, giving compliance to the 
requirements established in National Resolutions 236/93 and 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.

strengthened 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; 

signed a framework agreement with the Argentinean Environmental Authority for a mutual collaboration on 
environmental issues, particularly relating to climate change; and 

executed a pilot project on adaptation activities in a particular site of the company, using an adaptation tool that 
required the identification of climate risks, research on past, current and future climate trends and the 
identification of current taken and needed adaptation activities. In 2017, we implemented the same tool in 
another facility and co-organized in partnership with ARPEL (Asociación latinoamericana de empresas de 
Petróleo) a workshop on Climate Change vulnerability and adaptation. 

In relation with water management activities, the “Local Water Tool” has been implemented on two sites for the identification of water 
risks and practices taken of the proper management of water and effluents during 2016, continuing the implementation in 2017 in 
another two sites. Furthermore, during the past years a baseline study on water management has been performed for the different 
facilities of the company, which allowed us to establish the points of water intake and water disposal (effluent) with corresponding 
volumes. Focusing on the development and research, the company created YPF Tecnología S.A. (see “Item 4. Information on the 
Company—Research and Development”) where environmental activities are being undertaken in different fields. In particular, during 
2016 we started performing activities on strengthening the biological restoration of sites which were continued during 2017. These 
activities were supported by local universities as well. 

Our estimated capital expenditures are based on currently available information and on current laws. Any future information or future 
changes in laws or technology could cause a revision of such estimates. Changes in management’s business plans or in Argentine laws 
and regulations may cause expenditures to become material to our financial position, and may affect results of operations in any given 
year. 

Waste Management 

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 65% of the stock in our repositories from 2012 to 2017. 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. 

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.

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 Neuquen 
province. 

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. 

Furthermore, as previously mentioned, in 2017 we continued the activities started in 2016 on strengthening the biological treatment of 
certain sites, particularly in the Santa Cruz province. 

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 the Argentine Oil and Gas 
Business and Our Business—Our domestic operations are subject to extensive regulation” and “Item 3. Key Information—Risk 
Factors—Risks Relating to the Argentine Oil and Gas Business and Our Business—Oil and gas activities are subject to significant 
economic, environmental and operational risks.” 

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 environment 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). 

95 

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. 

Following the hydrogeological studies that took place in 2015 and 2016, during 2017 YPF focused its studies on gathering 
hydrogeological information by electric profiles and water samples in order to perform a regional hydrogeological study for all the 
convencional and non-conventional areas in 2018. This hydrogeological study will cover not only the traditional hydrogeological 
aspects but also the assessment on the quality of the water for irrigation and potable water. In addition, the aim of this study is to 
identify the depth of the aquifer that should 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. 

In this context, YPF has started a transformation process to become an integral energy company and the leader for sustainable energy 
development in Argentina. 

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. 

We know that energy transition cannot happen overnight. This is why, 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. 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 2017, we designed and approved our corporate sustainability policy and our commitment to climate change and we structured the 
corporate sustainability department. 

We also renewed our commitment to the UN Global Compact and its Ten Principles on Human Rights, Labor Rights, the Environment 
and the Fight against Corruption, and keep participating as a Board member of the Argentine Network. 

We carried on a process to explore the role that the company should play to contribute towards the 2030 Global Agenda for Sustainable 
Development, particularly in the framework of the country endorsement. Some initiatives in line with these Sustainable Development 
Goals are already under way and this process will continue for the next few years. 

We have defined and developed the contents of this Report by taking into account those internal and external groups, because we 
believe that the only way to create value for our stakeholders is by understanding 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, and reputation and brand positioning research, among others. The 
materiality assessment undertaken to shape the content of this annual sustainability report serves as both a retrospective and forward 
looking review of our priorities. This assessment re-emphasised the following stakeholder concerns:

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—Logistics Division.” As of December 31, 2017, 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 “—Exploration and Production Overview—Main properties.” In addition, as of December 31, 2017, we leased 84 
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. 

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 the Argentine Oil 
and Gas Business and 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 the Argentine Oil and Gas Business and 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 the 
Argentine Oil and Gas Business and 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. 

97 

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 
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. A mutual hold-harmless provision for indirect damages such as those 
resulting from loss of use or loss of profits is normally included. 

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 Law No. 27,007 enacted in 2014, which established the general legal 
framework for the exploration and production of oil and gas, and 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, 
amending 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. 

98 

In October 2004, the Argentine congress enacted Law No. 25,943, creating a new state-owned energy company, 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 hydrocarbon production concessions where association agreements with 
ENARSA have not been signed and reverting them to the Argentine Secretariat of Energy (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 that it communicated its decision not to convert the association agreements related such Areas to the 
Operators of Areas “ENARSA 2” and “ENARSA 3”. As of the date of this annual report, negotiations related to Area ENARSA 1 are 
ongoing. 

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. 

Ownership of hydrocarbons reserves was transferred to the provinces through the enactment of the following legal provisions that 

effectively amended the Hydrocarbons Law: 

•

•

•

•

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. 

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 of the Republic of Argentina. 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. 

99 

Article 3 of the Expropriation Law provides that the principles of the hydrocarbon policy of the Republic of Argentina are the 

following: 

(a) 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; 

(b) Convert hydrocarbon resources to proved reserves and their exploitation and the restoration of reserves; 

(c)

Integrate public and private capital, both national and international, into strategic alliances dedicated to the exploration and 
exploitation of conventional and unconventional hydrocarbons; 

(d) Maximize the investments and the resources employed for the achievement of self-sufficiency in hydrocarbons in the short, 

medium and long term; 

(e)

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; 

(f)

Promote the industrialization and sale of hydrocarbons with a high added-value; 

(g) Protect the interests of consumers with respect to the price, quality and availability of hydrocarbon derivatives; and 

(h) 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. 

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. 

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. 

See “—Law No. 26,932” for descriptions 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, 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.

the SEC on May 9, 2012. 

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. 

101 

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. 1277/2012 

Decree No. 1277/12 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. 1055/89, sections 1, 6 and 9 of Decree No. 1212/89 and sections 3 
and 5 of Decree No. 1589/89. Decree No. 1277/12 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. 1277/12 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 the 
Commission. 

With respect to the refining industry, Decree No. 1277/12 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 of the Republic of Argentina, 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.” 

Decree No. 272/2015 

On January 4, 2016, Decree No. 272/2015 was published in the Official Gazette of the Republic of Argentina, which modified 
Decree No. 1277/12. 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. 

102 

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. 

Decree No. 2/2017 

On January 3, 2017, Decree No. 2/2017 was published in the Official Gazette of the Republic of Argentina, modifying the 
Ministries Law No. 22,520. Among other changes, it split the Ministry of Economy and Public Finance, creating the Ministry of 
Economy and the Ministry of Finance and separating their respective powers and responsibilities. 

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. 1172/03, 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. 1172/03 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.1172/03. 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. 

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 of the Republic of Argentina, guaranteeing a right 

of access to public information. This right includes the ability to freely seek, access, request, receive, copy, analyze, process, use and 
distribute information in possession of the bound parties as defined under the law. State-owned companies, companies with majority 
state-owned capital, mixed-economy companies and all other business organizations where the National State has a majority interest in 
capital or in the formation of corporate decisions are deemed bound parties, except for companies authorized to make public offerings 
of their securities. Law No. 27,275 has come 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 of the Republic of Argentina, 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 definition of bound parties, as described in Law No. 27,275, will come into effect 
the day after their publication in the Official Gazette. 

On March 28, 2017 Regulatory Decree No. 206/2017 was published in the Official Gazette of the Republic of Argentina and came into 
effect on September 29, 2017, which regulates certain aspects ot Law No. 27,275, including further clarifications with respect to scope 
of the exceptions to the obligation of the bound parties to furnish certain information. 

103 

Law No. 27,007, amending the Hydrocarbons Law 

On October 31, 2014, Law No. 27,007 amending the Hydrocarbons Law was published in the Official Gazette of the Republic of 
Argentina. 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. 

•

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 Argentine Secretariat of Energy. 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%. 

104 

• 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 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 Argentine 
Secretariat of Energy 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 Argentine Secretariat of Energy. 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”. 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”. As of the date of this annual report, negotiations related to Area ENARSA 1 
are ongoing. 

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 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” 3500 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—Results of Operations—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. 

105 

MINEM Decree No. 192/2017 

On March 21, 2017, Decree No. 192/2017 was published in the Official Gazette of the Republic of Argentina, 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 is 
obligated to register such operation in the Registry and obtain authorization from the MINEM before the import takes place. The 
registration of the operation with the MINEM will be filed in accordance with a specific proceeding that the MINEM will establish for 
such purpose. 

According to this decree, the MINEM will also 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 excepts 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”). 
Decree No. 192/2017 was in force until December 31, 2017, according to Decree No. 962/2017 (published in the Official Gazette of the 
Republic of Argentina 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. 

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 ceased to be enforceable. 
See “—Taxation.” 

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 Argentine Secretariat of Energy 
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 Argentine MINEM 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 

106 

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, 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 

107 

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 Argentine Secretariat of Energy, 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 Argentine Secretariat of Energy, 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. 1077/2014 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. 

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. 

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 

108 

•

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 Argentine Secretariat of Energy 

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 the Argentine Oil and Gas Business and 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 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 “—Exploration and Production 
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 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. 

In connection with the extension of concessions, see “—Exploration and Production 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. 

109 

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. 

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 Argentine Secretariat of Energy 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 Argentine Secretariat of Energy 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. 

110 

Executive Decree No. 2014/08 of November 25, 2008, created the “Refining Plus” program to encourage the production of diesel 

and gasoline. The Argentine Secretariat of Energy, by S.E. Resolution No. 1312/08 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 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 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 Oil Deregulation 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 
Oil Deregulation 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 Oil Deregulation 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. 1679/04, S.E. 
Resolution No. 532/04 and Ministry of Economy Resolution No. 394/07) 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. 1277/2012” 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, amending the Hydrocarbons Law” and 
“—Decree No. 272/2015.” 

111 

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. 2014/08 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 Argentine Secretariat of Energy, through 
S.E. Resolution No. 1312/08 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 
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 
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. 1330/2015 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. 1390/09 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. 

112 

The 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 Argentine Secretariat of Energy. S.E. Resolution No. 1,879/05 established that refining companies registered by the 
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. 1679/04 reinstalled 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. 1338/06 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 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. 1679/04; 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. 

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. 1277/2012.” 

113 

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. 1283/2006, 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 350mg/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. By the end 
of 2019, the soybean export tax will be 18%, down from its current level of 30%. 

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.” 

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 Resolution No. 3823. 

Resolution No. 5/2015 also established that importers of products included in the Mercosur Tariff Code must obtain an 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 Import 
Monitoring System (Sistema Integral de Monitoreo de Importaciones) (“SIMI”) created by AFIP Resolution No. 3823. 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. 

114 

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 Executive Branch (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 is the application authority. 

Decree N° 629/2017 

Decree N° 629/2017—published in August 10, 2017 in the official Gazzette of the Republic of Argentina- introduces a “Regime for the 
Import of Used Good for the Oil & Gas Industry” (the “Régime”), 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 companies registered under the Registry of Oil Companies and companies 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 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 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 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 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. 

115 

The 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 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 Argentine Secretariat of Energy, which demands compliance with 
commitments already assumed. 

The 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 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. 1417/08, the Secretariat of Energy determined the basin prices for the residential 
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, the Official Gazette published S.E. Resolution No. 55/2012 of the Secretariat of Energy, 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. 1070/2008 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. 1410, 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 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. 1982/11, which supplements Decree 
No. 2067/08. This Resolution adjusts the tariff charges established by Executive Decree No. 2067/08 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. 1991/11, 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. 

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. 

116 

On November 5, 2012 the Official Gazette published Law No. 26,784 which approves 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. 2067/08 and 
all its supplementary acts shall be ruled by Law No. 26,095. 

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. 

On October 4, 2010, the Official Gazette published ENARGAS Resolution No. 1410/10, 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 Argentine Secretariat of Energy would have allocated by virtue of Agreement 2007-2011 ratified by the Resolution 
No. 599/07. See “—Exploration and Production Overview—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. 

Rules established by ENARGAS Resolution No. 1410/10 were 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, establishes 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, reduces 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 establishes the “Supplementary Procedure for Gas Requests, Confirmations and 
Control.” 

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. 

In addition, on June 1, 2016, MINEM published Resolution No. 89/2016, which: 

• Requires 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. 

• Establishes 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, reduces the contracted volume requirement in accordance with the framework provided by Resolution 
No. 1,410/2010. 

117 

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 for Priority Demand will have priority over other segments.Theconfirmation 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. 

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 in the notice of call that before the end of the extension period established in Law 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 US 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. 

118 

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 
established in the Agreement. 

On August 27, 2012, the Official Gazette published S.E. Resolution No. 1445/2012 of the Secretariat of Energy, 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. Addionally, 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 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. 

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. 

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 US dollars and at an interest rate of 8% per annum 
maturing in 2020 (“BONAR 2020 US$”). 

119 

Accordingly, 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. 

MINEM Resolution No. 97/2018 

On April 3, 2018, the Ministry of Energy and Mining published Resolution N° 97/2018 in the Official Gazette that approves the 
procedure for cancelation of the pending compensations under the “Natural Gas Additional Injection Stimulus Program”, the “Natural 
Gas Injection Stimulus Program for Companies with Reduced Injection” and the “Natural Gas New Projects Program” corresponding to 
2017 natural gas injections (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. 

In order to determine the amount of the compensation, the Secretariat of Hydrocarbon Resources shall issue a “Resolution of 
Compensation”, calculated as follows: 

1. 85%: the amount in USD calculated using the exchange rate at the time of injection of the natural gas. 

2. 15%: the amounts in USD calculated using the exchange rate between the time of injection and the time of payment due or the 

exchange rate as of the date of the Resolution, as per corresponds. 

The compensation shall be monthly paid in 30 equal and consecutive payments as from January 2019 using the exchange rate 
“Comunicacion A 3500 Mayorista” corresponding to each payment of each month. 

Gas producing companies joining the Procedure shall waive all claims, legal actions and measures as well as accept the terms and 
conditions of payment compensations under the Procedure during the maximun period of 20 working days since the publication of the 
Resolution in the Official Gazette of the Republic of Argentina. As of the date of this annual report we are analyzing the necessary steps 
to comply with said Resolution. 

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. 

120 

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 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. 

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 
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. 

On November 17, 2017, Resolution MINEM 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. 

Tariffs 

On April 4, 2014, Resolution S.E. No. 226/2014 of the 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. 

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 (Transport System Entering Point)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%; 

121 

• Users R34: 400%; and 

• Users SGP: 500%. 

It further sets forth that the increase limits established above on the final invoiced 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. 4044/2016, 4045/2016, 4046/2016, 4047/2016, 4048/2016, 4049/2016, 

4050/2016, 4051/2016, 4052/2016, 4053/2016 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. 

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). 

122 

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.

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. 

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. 

123 

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. 

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 
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. 

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. 

124 

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. 

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 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.

Natural gas export administration and domestic supply priorities 

In March 2004, the 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; 

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 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 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 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 
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 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 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 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. 1886/06, 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. 

126 

By means of S.E. Resolution No. 1329/06, later supplemented by S.S.C. Note No. 1011/07, the 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. 

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. 

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: 

• 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 Argentine Secretariat of Energy shall periodically publish reference prices 

for LPG sold in bottles of 45 kilograms or less; 

•

requires the Argentine Secretariat of Energy 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); 

127 

• 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 Argentine Secretariat of Energy on participants in the LPG industry. 

The 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 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 
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. 168/05 of the Undersecretariat of Fuels requires companies intending to export LPG to first obtain an 

authorization from the 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 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 Executive Branch 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 in 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. 

Though 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. 

128 

Through Resolution No. 41/2016, published in January 2016, which modifies Resolution No. 06/2016, 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 the 
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. 

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 926-E/2017, dated October 17, 2017 authorized CAMMESA the signature of purchase power 
agreements for YPF Energía Eléctrica S.A. 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. 

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. 

129 

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 Comercial Code, which sets forth the general rules of tort law. 

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 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. 1037/01 
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 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. 

130 

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 “—Exploration and Production.” 

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. 

See additionaly Note 30.l to the Audited Consolidated Financial Statements. 

Reduction in tax rates for fuels 

On December 30, 2014, Decree No. 2579/2014 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 follow (Laws 
No. 26,028 and 26,181 were repealed): 

1. 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. 

2.

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. As a result, export duties on 
hydrocarbons are no longer applied. 

We cannot give any assurances as to future levels of export taxes. 

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 uspstream 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. 

131 

After that, Decree No. 1722/2011 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. 1722/2011 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 7 (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. 

ITEM 4A. Unresolved Staff Comments. 

YPF does not have any unresolved Staff comments.

Our operating profit in 2017 was Ps. 16,073 million, compared to a loss of Ps. 24,246 million in 2016. 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 internal demand, market prices, availability of 

financial resources for our business plan and its corresponding costs and government regulations. 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 increasing productivity and efficiency in 2018. 
We believe that we need to create a more efficient industry that is sustainable in a lower crude oil price environment. Therefore, we 
estimate that we will not see production growth this year (estimated to be around 2% - 3% lower than 2017 on a boe basis). We expect 
to increase our capital expenditures during 2018 compared to 2017, reaching approximately U.S.$4 billion, mainly in our Upstream 
operations, considering the startup of new non-conventional projects. In addition, we expect a decrease of capital expenditures in our 
Gas and Power segment (mainly in conection with projects that will be executed by our former controlled company YPF Energía 
Eléctrica (See “Item 4—Information of the Company—Gas and Power—YPF in Power Generation.”) which are not going to be 
consolidated any more since 2018. 

Most of our shale oil production comes from the Loma Campana area through our joint venture with Chevron, which was the first 

and largest farm-out. As we gathered more experience, drilling activity migrated to horizontal wells, obtaining wells with a promising 
relation between expected EURs and well costs. As we pushed forward several initiatives to improve efficiency and significantly reduce 
well costs, we have been reducing the cost per fracture reaching at the end of 2017 an average cost of approximately U.S.$1.4 thousand 
for lateral foot (approximately 54% lower than the average cost in 2015). Our strategy is to continue to invest and de-risk, but at a 
slower pace than some years ago. 

Since October 2017, Crude oil prices in Argentina have been based on import parity and export parity references, , taking into 
account that domestic prices and costs had previously been decoupled from international prices. We expect to implement fuel price 
increases following international oil prices, Argentine peso and biofuel pricing evolution. We expect to preserve refining margins and 
do not expect refining margins to decrease going forward. Nevertheless, we cannot assure we will have the chance to implement those 
increases, principally considering the relevant conditions that affect the domestic market such as domestic demand and growth, among 
others. 

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 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 

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. 

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 to below 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. 

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. 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. As a 
result, it is difficult to predict the impact of these measures 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 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.See “Item 3. Key Information—Risk Factors—Risks Relating to 
the Argentine Oil and Gas Business and 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 the Argentine Oil and Gas Business and Our Business— 
We are exposed to the effects of fluctuations in the prices of oil, gas and oil products.”

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). 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 
2015, the preliminary GDP growth rate for 2016 and the preliminary GDP growth rate for 2017 published by INDEC were positive 
2.6%, negative 2.3% and positive 2.9%, respectively. 

The official exchange rate of the Argentine peso to the U.S. dollar as of December 31, 2016 was Ps. 15.85 per U.S.$1.00, a 
devaluation of approximately 21.9% compared to Ps. 13.01 per U.S.$1.00 as of December 31, 2015. In addition, 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. 

Argentina has confronted and continues to confront 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. 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, the CPI increased 24.8%. In January, 
February and March 2018, the CPI increased 1.8% ,2.4% and 2.3%, respectively. 

The wholesale price index increased 28.3%, 34.5% and 18.8% in 2014, 2016 and 2017 (provisional), respectively. In January, 

February and March 2018, the provisional wholesale price index increased 4.6%, 4.8% and 1.9%, respectively. Before the new 
administration took office, certain private sector analysts believed that inflation was significantly higher than the rate published by 
INDEC. 

See “Item 3. Key Information—Risk Factors—Risks Relating to Argentina—Our business is largely dependent upon economic 

conditions in Argentina.” 

During 2017, Argentina’s provisional trade balance was a deficit of approximately U.S.$ 8.5 billion according to preliminary 
estimates from INDEC, with total exports of approximately U.S.$ 58.4 billion during 2017, representing a 0.9% increase compared to 
the same period in 2016. Total imports were approximately U.S.$ 66.9 billion, representing an increase of 19.7% compared to the same 
period in 2016. 

The drop occurred some years ago in the international price of Brent crude has affected and will likely continue to affect the oil 
industry’s expected activities worldwide, particularly with respect to expected investments in the industry. 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. 

In 2016, following the continuous drop in the average international price of Brent crude, 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. 

136 

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. 

After the finalization of the 2017 Transitional Agreement, according to Argentina’s Ministry of Energy and Mining, hydrocarbons 

market in Argentina has become a completely liberalized market and oil and fuel prices must be set by the market conditions and 
fluctuate. This decision formally ends the transition to international oil price parity and consequently, it is expected that from 2018 
onwards, petroleum companies in Argentina will -establish -their own pricing policy. 

In general terms, the pricing policy of fuels depends on several factors such as crude oil prices, international refining spreads, 
processing and distribution costs, biofuel prices, exchange currencies, local demand and supply, stocks, local taxation, and domestic 
margins for our products, among others. 

As a result of these new market conditions, since October of 2017 YPF has been negotiating the prices of crude purchases with 
producer companies based on import parity and export parity references, and the fuel prices based on the factors discussed above. We 
expect to continue negotiating crude oil prices based on market condition and continue to apply the market-based fuel pricing strategy, 
in the future. See “Item 3. Key Information—Risk Factors—Risks Relating to Argentina—Limitations on local pricing in Argentina 
may adversely affect our results of operations.” 

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 
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 
market conditions and, thus, fluctuate. As mentioned before, this decision formally ended the transition to international oil price parity. 

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.”

Declining 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 282 mtn, 375 mtn and 462 mtn in 2017, 2016 and 2015, respectively. 

Due to the decreased export product volumes indicated above, the portion of our revenues accounted for by exports decreased 
steadily in recent years. Exports accounted for 8.7%, 7.8% and 7.9% of our consolidated revenues in 2017, 2016 and 2015, 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, with the recent adjustments in gas prices (See “Item 4. Information on the Company—Regulatory Framework and 
Relationship with the Argentine Government—Market Regulation—Natural Gas.”), which also affect de residential market where 
demand has demonstrated some sensitivity to gas price, we could be subject to seasonal fluctuations in our sales volumes, which could 
have negative impact on our level of natural gas production and sales. See “Item 3. Key Information—Risk Factors— Risks Relating to 
Our Business—Oil and gas activities are subject to significant economic, environmental and operational risks.” 

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, 2017, see Note 2.c 
to the Audited Consolidated Financial Statements. 

• Depreciation of oil and gas producing properties. See Note 2.b.6 to the Audited Consolidated Financial Statements. 

139 

• Asset retirement obligations. See Note 2.b.6 to the Audited Consolidated Financial Statements. 

•

•

Environmental liabilities, litigation and other contingencies. See Notes 2.c, 14.a and b., 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.25 to the Audited Consolidated Financial Statements as of December 31, 2017. 

In addition, for information regarding our estimates of oil and gas reserves, see “Item 4. Information on the 

Company—Exploration and Production—Oil and Gas reserves.” 

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, 2017, 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, 
2017, if the average of the oil prices used for impairment tests as of December 31, 2017 were reduced by U.S.$5 each year, holding all 
other factors constant, our ceiling test limitation related to the net book value of our proved oil properties would be reduced by 
approximately U.S.$1.5 billion. This hypothetical calculation was prepared assuming all other factors remain constant to isolate the 
impact of commodity prices on our ceiling test limitation. 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—Exploration and Production—Oil and gas production, production 
prices and production costs” and Note 19 to the Audited Consolidated Financial Statements.

increased by 19.5% from 2016 to 2017 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 (35%) mainly because: the 
registration of the deferred income tax as a result of the effect of applying the current tax rate (35%) 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 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.

Revenues in 2016 were Ps. 210,100 million, representing a 34.6% increase compared to Ps. 156,136 million in 2015. Among the 

main factors contributing to the increase were: 

• Diesel revenues increased by Ps. 14,303 million, or 25.2%, as a result of an increase in the average price for diesel mix of 

30.5%, partially offset by a decrease in sales volumes of 4.1%, despite an 8.3% increase in sales volumes of Infinia diesel, a 
premium diesel; 

143 

• Gasoline revenues increased by Ps. 11,298 million, or 32.3%, primarily as a result of an increase in the average price for 

gasoline mix of 34.1%, partially offset by a decrease in sales volumes of 1.3%, despite an 1.1% increase in sales volumes of 
Infinia gasoline; 

•

Fuel oil revenues in the Argentine domestic market increased by Ps. 2,583 million, or 36.6%, primarily as a result of an 
increase in the average price of 54.5%, partially offset by a decrease in sales volumes of 11.6%; 

• Natural gas revenues increased by Ps. 14,409 million, or 65.5%, primarily as a result of an increase of 67.8% in the average 
sale price in Argentine peso terms (or a 5.8% increase in U.S. dollar 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, partially offset by a decrease in sales volumes of 1.4%; 

• Natural gas revenues to the retail segment (residential and small general service category) increased by Ps. 2,866 million, or 
78.0%, primarily due to an increase in the average price of approximately 60.1% and an increase in sales volumes of 11.2%; 

Export revenues increased by Ps. 4,054 million, or 33.0%, primarily due to increases in exports of flour, grains and oils of 
38.8%, aerokerosene of 29.0%, and petrochemicals of 37.2%, all due to an increase in average prices in Argentine peso 
terms, partially offset by decreases in sales volumes; and 

Partially compensating for the effect of the above mentioned increments, in 2015, the Company recorded Ps. 1,988 million of 
revenue corresponding to the Crude Oil Production Stimulus Program (Programa de Estímulo a la Producción de Petróleo 
Crudo) set forth under Resolution No. 14/2015 of the Hydrocarbon Commission. See “Item 4. Information on the 
Company—Legal and Regulatory Framework and Relationship with the Argentine Government—Market 
Regulation—Resolution No. 14/2015.” This program was discontinued in 2016.

Cost 

Cost in 2017 was 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; 

144 

•

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. 

Cost of sales in 2016 was Ps. 177,304 million, representing a 48.3% increase compared to Ps. 119,537 million in 2015, including 

increases in production costs and purchases of 48.5% and 43.9%, respectively. Among the main factors contributing to this increase 
were: 

•

•

Property, plant and equipment depreciation costs increased by Ps. 17,371 million, or 67.6%, primarily as a result of 
(i) increased investments in assets 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; 

Total lifting costs increased by Ps. 8,405 million, or 29.1%, considering an increase of the unit indicator in Argentine peso 
terms of 28.2%; 

• Refining costs increased by Ps. 2,530 million, or 42.0%. 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 44.2%; 

• Royalty payments increased by Ps. 5,163 million, or 45.7%, primarily as a result of increases of (i) Ps. 3,179 million related 
to crude oil production and (ii) Ps. 1,984 million related to natural gas production, due to the higher wellhead values of these 
products; 

•

•

•

•

Transportation costs increased by Ps. 2,156 million, or 45.0%, mainly due to increases in rates in 2016; 

Purchases of crude oil from third parties increased by Ps. 2,228 million, or 19.5%, primarily as a result of an increase in 
average prices charged by third parties in Argentine peso terms of approximately 35%, which was mainly related to the 
devaluation of the Argentine peso, in comparison, there was a 13.4% decrease in average prices charged by third parties in 
U.S. dollar terms, partially offset by a decrease in purchased volumes of approximately 11.4%; 

Purchases of biofuels increased by Ps. 5,454 million, or 70.5%, primarily as a result of an increase in the average prices of 
FAME and ethanol biofuel of approximately 76.3% and 45.6%, respectively, and an increase in purchased volumes of 
FAME and ethanol biofuel of 1.4% and 11% (due to an increase in the cut rate of naphthas), 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. 2,274 million, or 78.2%, primarily as a result of an increase in the purchase price 
of approximately 70.0% and an increase in purchased volumes of 4.8%; and 

• Grain purchases in the agricultural sales segment through the form of barter, which were recorded as purchases for 

accounting purposes, increased by Ps. 1,526 million, or 58.1%. This increase is due to an increase in the average price of 
approximately 91.1%, partially offset by a decrease in volumes of 17.3%. 

All of this was partially offset by the following: 

•

Imports of fuels decreased by Ps. 621 million, or 10.0%, primarily as a result of a decrease in purchased volumes of gas oil 
of 38.5%, partially offset by an increase in imported volumes of gasoline and jet fuel of 15.7% and an increase in average 
prices of fuels of 23.9%; and 

• Additionally, insurance payments related to the losses suffered from an incident at our La Plata refinery in April 2013 were 
Ps. 615 million in 2015, which did not recur in 2016. This had a negative impact on cost of sales for 2016 compared to the 
same period in 2015. In addition, with respect to the incident that affected the facilities of our oil treatment plant in Cerro 
Divisadero in Mendoza in March 2014, an insurance payment amount of Ps. 1,165 million was recorded in 2015, of which 
Ps. 794 million was recorded as a lower cost for purchases and Ps. 371 million as other operating income, which did not 
recur in 2016. 

145 

Administrative expenses 

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. 

Administrative expenses in 2016 were Ps. 7,126 million, representing a 27.6% increase compared to Ps. 5,586 million in 2015, 

primarily as a result of increases in personnel costs and IT service contracts. 

Selling expenses 

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. 

Selling expenses in 2016 were Ps. 15,212 million, representing a 37.1% increase compared to Ps. 11,099 million in 2015, 
primarily as a result of higher charges for product transportation, mainly related to increased rates for the transportation of fuels in the 
domestic market, as well as increases in personnel costs, charges related to depreciation of property, plant and equipment, advertising 
and promotional activities, and in the provision for doubtful accounts, which was negatively affected by recoveries in the provision for 
doubtful accounts in the natural gas distribution segment in 2015. 

Exploration expenses 

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. 

Exploration expenses in 2016 were Ps. 3,155 million, representing a 27.6% increase compared to Ps. 2,473 million in exploration 
expenses in 2015, primarily as a result of a Ps. 625 million increase in negative results from unproductive exploratory drilling in 2016 
compared to 2015. Additionally, expenditures for the development of geological and geophysical studies did not vary significantly in 
2016 compared with 2015. However, total investments in exploration decreased Ps.1,375 million, or 49.7%, compared to 2015. 

Recovery / (Impairment) of property, plant and equipment and intangible assets 

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. 

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 Argentine 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 “Item 5. Operating 
and Financial Review and Prospects—Critical Accounting Policies” and Note 2.c to the Audited Consolidated Financial Statements as 
of December 31, 2017. 

Other net operating results 

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 areaand the 
temporary economic assistance accrued by our subsidiary Metrogas. 

146 

Other net operating results, in 2016 were a gain of Ps. 3,394 million, or 101.8%, compared to the gain of Ps. 1,682 million in 

2015. In 2016, other net operating results mainly includes 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, 2016) 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. The remaining variation mainly corresponds to a Ps. 199 million decrease in construction incentives received by our subsidiary 
A-Evangelista S.A and a Ps. 48 million increase in the temporary economic assistance accrued by our subsidiary Metrogas. 

Operating Income / (loss) 

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. 

Operating loss in 2016 was Ps. 24,246 million due to the factors discussed above, representing a 246.2% decrease compared to a 

gain of Ps. 16,588 million in 2015. 

Financial results, net 

In 2017, financial results, net, was 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. 

In 2016, financial results, net, was a loss of Ps. 6,146 million, representing a 150.6% decrease compared to income of Ps. 
12,157 million in 2015. The Company recorded lower positive foreign exchange differences on net monetary liabilities in pesos of Ps. 
8,603 due to lower devaluation of the Argentine peso against the U.S. dollar in 2016 compared to the same period in 2015. The 
Company recorded higher interest expenses and other financial expenses of Ps. 9,700, as a result of higher average indebtedness and 
higher interest rates in 2016 compared to the same period in 2015. The average net debt in 2016 was Ps. 116,976 million, while the 
average net debt in 2015 was Ps. 64,956 million. The average amount of net debt was calculated as the linear average of current and 
non-current loans at the beginning and end of the corresponding period, net of the linear average of cash and cash equivalents at the 
beginning and end of the corresponding period. 

Income tax 

Income tax in 2017 was 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. 

Income tax in 2016 was a gain of Ps. 1,425 million, representing a 105.8% decrease compared to a loss of Ps. 24,637 million in 
2015. This decrease was mainly due to lower deferred tax of Ps. 27,313 million, partially offset by an increase of Ps. 1,251 in current 
income tax. The lower deferred tax charge is due to the recognition of the deferred tax assets of Ps. 12,230 related to the impairment for 
property, plant and equipment discussed above and the lower difference generated by the revaluation of the book value of the 
Company’s property, plant and equipment in U.S. dollars, which is the functional currency of the Company, with respect to the tax 
values of property, plant and equipment held in historical Argentine pesos to be deducted from tax as they are depreciated and the lower 
devaluation of the Argentine peso in 2016. 

Net profit / (loss) for the year 

Net profit / (loss) in 2017 was 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 was a gain of Ps. 34,589 million, compared to a loss of Ps. 

965 million in 2016. 

Net profit / (loss) in 2016 was a loss of Ps. 28,379 million, representing a 741.2% decrease compared to a net income of Ps. 

4,426 million in 2015. 

147 

Other comprehensive income in 2016 was Ps. 27,414 million, representing a 37.4% decrease compared to Ps. 43,758 million in 

2015. This decrease was mainly attributable to lower appreciation of property, plant and equipment. 

As a result of the foregoing, total comprehensive income in 2016 was a loss of Ps. 965 million, representing a 102.0% increase 

compared to a gain of Ps. 48,184 million in 2015. 

Consolidated results of operations by business segment for the years ended December 31, 2017, 2016 and 2015 

In 2016, our activities related to power generation and natural gas distribution was separated from the Downstream activities. See 

“Item 4. Information on the Company—Business Organization.” 

See the table of revenues and operating income for each of our business segments for the years ended December 31, 2017, 2016 

and 2015 in “Item 4. Information on the Company—Business Organization.” 

Upstream 

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. 

Operating income in 2017 for the Upstream business segment was a gain of Ps. 3,877 million, compared to a loss of Ps. 

26,845 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. 

148 

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 results 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. 

Revenues from the Upstream business segment in 2016 were Ps. 114,143 million, representing a 42.2% increase compared to Ps. 

80,287 million in 2015. 

Operating income in 2016 for the Upstream business segment was a loss of Ps. 26,845 million, including an impairment for 
property, plant and equipment of Ps. 34,943 million in 2016, compared to a gain of Ps. 7,535 million in 2015, including an impairment 
for property, plant and equipment and intangible assets of Ps. 2,535 million in 2015. 

This decrease in operating income was principally due to the following factors: 

•

The intersegment oil price measured in U.S. dollars decreased 13.1%, while increasing 38.8% in Argentine peso terms. Oil 
production in 2016 reached 244,700 barrels per day, representing a 2.0% decrease compared to 2015. This contributed to the 
increase of 82 mcm of crude oil, or 0.6%, transferred from the Upstream business segment to the Downstream business 
segment and a decrease of approximately 40 mcm of crude oil, or 8.4%, in sales to third parties; and 

• Natural gas production in respect of our operations in Argentina in 2016 reached 44.6 mmcm per day, representing a 0.9% 

increase compared to 2015. With the exception of the YSUR production, all natural gas produced, net of internal 
consumption, is assigned to the Gas and Power segment for sale to third parties (in the case of YSUR, the Gas and Power 
segment is solely responsible for the commercialization of the gas produced by YSUR). Sales volumes decreased 1.4% in 
2016 compared to 2015. 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 and YSUR’s natural gas production. The average natural gas revenue 
recorded by the Company in 2016, including revenues from the Gas Plan, was U.S.$4.76 per million BTU, a 5.8% increase 
compared to U.S.$4.50 per million BTU in 2015. 

All of this was more than offset by the following: 

•

•

In 2015, the Company recorded Ps. 1,988 million corresponding to the Crude Oil Production Stimulus Program (Programa 
de Estímulo a la Producción de Petróleo Crudo) set forth by Resolution No. 14/2015 of the Hydrocarbon Commission. See 
“Item 4. Information on the Company—Legal and Regulatory Framework and Relationship with the Argentine 
Government—Market Regulation —Resolution No. 14/2015.” This program was discontinued as of 2016. 

Total operating costs in respect of our operations in Argentina in 2016 were Ps. 103,965 million (excluding exploration 
costs), representing a 51.9% increase compared to Ps. 68,421 million in 2015. Among the main factors contributing to the 
increase were: 

•

Property, plant and equipment depreciation costs increased by Ps. 15,050 million, or 65.2%, 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; 

149 

•

•

•

Total lifting costs increased by Ps. 8,405 million, or 29.1%, considering an increase of the unit indicator in Argentine 
peso terms of 28.2%; 

Royalty payments increased by Ps. 5,163 million, or 45.7%, primarily as a result of increases of (i) Ps. 3,179 million 
related to crude oil production and (ii) Ps. 1,984 million related to natural gas production; and 

Transportation costs increased by Ps.641 million, or 40.2%, mainly due to increases in rates in 2016. 

Exploration expenses in 2016 were Ps. 3,155 million, representing a 27.6% increase compared to Ps. 2,473 million in exploration 
expenses in 2015, primarily as a result of a Ps. 625 million increase in negative results from unproductive exploratory drilling in 2016 
compared to 2015. Additionally, expenditures for the development of geological and geophysical studies did not vary significantly in 
2016 compared with 2015. However, total investments in exploration decreased Ps.1,375 million, or 49.7%, compared to 2015. 

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 2015, the Company recognized an impairment of property, plant and equipment and intangible assets for Ps. 2,535 million, 
mainly due to a reduction in the price of domestically traded oil in the short term and a reduction in expected medium and long-term 
international prices. This loss impacted the assets of fields in Argentina with reserves and oil production in the amount of Ps. 
2,361 million and the assets of fields with crude oil production in the United States for Ps.174 million. 

In 2016, other net operating results includes 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. 

With respect to the incident that affected the facilities of our oil treatment plant in Cerro Divisadero in Mendoza in March 2014, 

an insurance payment amount of Ps. 1,165 million was recorded in 2015, which did not recur in 2016, and of which Ps. 794 million was 
recorded as a lower cost for purchases and Ps. 371 million as other operating income. 

Downstream 

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 income 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 income is primarly 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; 

150 

•

•

•

•

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. 

Revenues from the Downstream business segment in 2016 were Ps. 163,463 million, representing a 30.0% increase compared to 

Ps. 125,766 million in 2015. 

Operating income for the Downstream business segment in 2016 was Ps. 3,093 million, representing a 55.5% decrease compared 

to Ps. 6,948 million in 2015. This decrease in operating income is primarily due to the following factors: 

•

The average volume of oil processed per day in YPF’s refineries decreased 1.8% to 293,500 barrels of oil per day, with 
decreased production of diesel by 1.3%, gasoline by 1.0% and fuel oil by 16.0% and with increased production of LPG by 
8.8% and petrochemical gasoline by 5.6%; 

151 

• Diesel revenues increased by Ps. 14,303 million, or 25.2%, as a result of an increase in the average price for diesel mix of 
approximately 30.5%, partially offset by a decrease in sales volumes of approximately 4.1%, despite an 8.3% increase in 
sales volumes of Infinia diesel, a premium diesel; 

• Gasoline revenues increased by Ps. 11,298 million, or 32.3%, primarily as a result of an increase in the average price for 

gasoline mix of approximately 34.1%, partially offset by a decrease in sales volumes of approximately 1.3%, despite a 1.1% 
increase in sales volumes of Infinia gasoline; 

•

•

•

Fuel oil revenues in the Argentine domestic market increased by Ps. 2,583 million, or 36.6%, primarily as a result of an 
increase in the average price of approximately 54.5%, partially offset by a decrease in sales volumes of approximately 
11.6%; 

Export revenues obtained by the Downstream segment increased by Ps. 3,979 million, or 32.5%, primarily due to increases 
in exports of flour, grains and oils of 38.8%, aerokerosene of 29.0%, and petrochemicals of 37.2%, all due to an increase in 
average prices in Argentine peso terms, partially offset by decreases in sales volumes; and 

Imports of fuels decreased by Ps. 621 million, or 10.0%, primarily as a result of a decrease in purchased volumes of gas oil 
of 38.5%, partially offset by an increase in imported volumes of gasoline and jet fuel of 15.7% and an increase in average 
prices of fuels of 23.9%. 

All of this was more than offset by the following: 

•

•

Purchases of crude oil increased by Ps. 23,744 million, or 36.1%, primarily as a result of an increase in oil prices of 
approximately 38.0% in Argentine peso terms as a result of the devaluation of the Argentine peso against the U.S. dollar, 
partially offset by a decrease in purchased volumes. Crude oil transferred volumes from the Upstream business segment 
increased by 0.6% (approximately 82 mcm), and crude oil purchased volumes from third parties decreased approximately 
11.4% (approximately 304 mcm); 

Purchases of biofuels increased by Ps. 5,454 million, or 70.5%, primarily as a result of an increase in the average prices of 
FAME and ethanol biofuel of approximately 76.3% and 45.6%, respectively, and an increase in purchased volumes of 
FAME and ethanol biofuel of 1.4% and 11% (due to an increase in the cut rate of naphthas), respectively; 

• Grain purchases in the agricultural sales segment through the form of barter, which were recorded as purchases for 

accounting purposes, increased by Ps. 1,526 million, or 58.1%. This increase is due to an increase in the average price of 
approximately 91.1%, partially offset by a decrease in volumes of 17.3%; 

•

•

•

Property, plant and equipment depreciation increased by Ps. 2,504 million, or 100.5%, primarily as a result of (i) increased 
investments in assets (in particular, the launch of the new Coke unit at the La Plata refinery) 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. 3,820 million, or 35.6%, primarily as a result of (i) increases in transport expenses, mainly 
related to increased fuel prices in the Argentine domestic market and (ii) the increase in the depreciation of assets linked to 
commercial use and of advertising and promotional activities; and the provision for contingencies increased in 2015 by Ps. 
650 million in connection with a ruling against YPF regarding a claim filed by the Union of Consumers and Users (Unión de 
Usuarios y Consumidores) for claims alleging that excess fees were charged to LPG consumers during the period 1993 to 
1997; 

Production costs related to refining costs increased by Ps. 2,530 million, or 42.0%. This increase was driven by higher 
charges for consumption of materials, spare parts, electricity and other supplies and fuels As a consequence of this, and 
considering also that the level of processing in refineries was 1.8% lower, the cost of unit refining increased by 44.2% in 
2016 compared to 2015. In turn, transportation costs related to production (naval and pipelines) increased by Ps. 
1,182 million, or 40.0%. 

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 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 

152 

The operating income for the Gas and Power business segment in 2017 was 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, c compared to an 
operating profit of Ps. 310 million in 2016. There were also better operating results from our subsidiary company YPF Energía Eléctrica 
S.A. attributable to this segment. 

The operating income for the Gas and Power business segment in 2016 was a gain of Ps. 2,008 million, representing a 34.0% 
increase compared to a gain of Ps. 1,498 million in 2015. This increase was mainly due to (i) the improved results in pesos obtained by 
LNG regasification services in Bahía Blanca and Escobar, which rates are set in U.S. dollars, (ii) the improved results obtained by our 
subsidiary YPF Energía Eléctrica S.A. and (iii) the Transitional Economic Assistance of Ps. 759 million accrued by our subsidiary 
Metrogas in 2016 in comparison with Ps. 711 million accrued in 2015. 

Central Administration and Others 

The operating loss for the Central Administration and Others in 2017 was 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 income 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. 

The operating loss for the Central Administration and Others in 2016 was a loss of Ps. 1,615 million, representing a 30.7% 

decrease in loss compared to a loss of Ps. 2,331 million in 2015. During 2016, this group of activities includes a net income of 
Ps.1,528 million attributable to the deconsolidation of the Maxus Entities (see Note 27 to the Audited Consolidated Financial 
Statements), offset by the increase in personnel costs, mainly due to higher wages, IT service contracts and depreciation of property, 
plant and equipment. 

Liquidity and Capital Resources 

Financial condition 

Total loans outstanding as of December 31, 2017, 2016 and 2015 were Ps. 191,063 million, Ps. 154,345 million and Ps. 

105,751 million, respectively, consisting of (i) current loans (including the current portion of non-current loans) of Ps. 39,336 million 
and non-current loans of Ps. 151,727 million as of December 31, 2017, (ii) current loans of Ps. 26,777 million (including the current 
portion of non-current loans) and non-current loans of Ps. 127,568 million as of December 31, 2016 and (iii) current loans of Ps. 
27,817 million (including the current portion of non-current loans) and non-current loans of Ps. 77,934 million as of December 31, 
2015. As of December 31, 2017, 2016 and 2015, 77%, 70%, and 73% 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, 2017, we had repurchased Ps. 309 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. 

The following tables set forth our consolidated cash flow information for the periods indicated.

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 Argentine Bonds denominated in U.S. Dollars due 2020 (“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. 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 the Argentine Oil and Gas 
Business and 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. 49,183 million in 2016 compared to Ps. 41,404 million in 2015. This 19% 

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 intangible assets, increased non-cash provisions, which did not 
involve expenditures, and lower income tax. This was partially offset by an increase in working capital in 2016 related to the accrual of 
accounts receivable, including the Gas Plan. In addition, in 2016, we received pending payments under the Gas Plan until December 31, 
2015, through the delivery of public debt instruments, specifically Argentine Bonds denominated in U.S. Dollars due 2020 (“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. 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. Cash flows used in investing activities were Ps. 66,174 million in 2016, compared to Ps. 
64,049 million in 2015, representing a 3% increase compared with 2015, which related mainly to investments made by our Upstream 
business segment and investment in our refineries. 

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.Net cash flows provided by financing activities in 2016 were Ps. 
10,817 million, which came primarily from the issuance of notes in the local market and international markets, net of repayments of 
principal and interest, including issuance of notes in the international debt capital markets for an aggregate principal amount of Ps, 
13.3 billion, U.S.$1.2 billion and of CHF 0.3 billion.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. In 2015, at the shareholders’ ordinary and extraordinary general meeting held on April 30, 
2015, a dividend of Ps. 503 million (Ps. 1.28 per share or ADS) was authorized for payment in 2015. 

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, 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.

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

(1) 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. 

(2) 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, 2017 for all periods. See additionally “Item 5. Operating and Financial Review and 
Prospects—Liquidity and Capital Resources—Covenants in our indebtedness.” 

(3) 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. 

(4) 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, 2017. 

155 

(5) Provisions for contingent liabilities under commercial contracts, which amounted to U.S.$ 664 million as of December 31, 2017, 
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.$ 12.3 billion as of December 31, 2017. The table includes the portion of this 
amount for which contracts have been executed. 

(7) The table is presented in U.S.$, which is the Company’s functional currency. 
(8)

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, 2017. 

We have additional commitments under guarantees. For a discussion of these additional commitments see “—Guarantees 

provided.” 

Covenants in our indebtedness 

Our financial debt generally contains customary covenants. With respect to a significant portion of our financial debt totaling Ps. 
191,063 million, including accrued interest (current and non-current debt) as of December 31, 2017, we have agreed, among other 
things and subject to certain exceptions, not to establish liens or charges on our assets. In addition, approximately 52 % of our debt 
outstanding as of December 31, 2017 were subject to financial covenants related to our leverage ratio and debt service coverage ratio. 

Bank credit facilities together with capital market debt provide a material source of liquidity for the Company. Under the terms of our 
credit agreements and indentures, if we fail to comply with the covenants previously described or fail to remedy them during an 
established period of time, we will be in default; an event that would limit our capacity of borrowing under our credit facilities and 
would therefore materially limit our sources of liquidity. 

In addition, upon an event of default, any creditor, including the holders of outstanding notes amounting to Ps. 165,154 million as of 
December 31, 2017, may declare due and immediately payable the principal and accrued interest on amounts owed to them, which 
could result in other accelerations due to cross default provisions.As of the date of this annual report, none of our debt is under any 
event of default that could trigger an acceleration provision. As of December 31, 2017, we were in compliance with all covenants in 
connection with our indebtedness. 

Guarantees provided 

As of December 31, 2017, in relation to compliance with obligations of subsidiaries, YPF has issued bank guarantees for an 
approximate amount of US$ 26 million and has assumed other commitments for an approximate value of US$ 42 million. 

Additionally, see Note 29.b 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 guaranteed financial debt.

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. 

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. The information provided below describes the composition and responsibilities of our Board of Directors and committees 
as of the date of this annual report.

Board of Directors 

Composition of our Board 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 composed of 11 to 21 members and up to an equal number of alternates. Alternates 
are those elected by the shareholders or the Supervisory Committee, when applicable, 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 the duties of a director. 

Directors shall hold office from one to three years, as determined by the shareholders’ meetings. As of the Shareholders’ Meeting held 
on April 28, 2017, our Board of Directors was composed of 15 directors and 11 alternates.

alternate. 

Under the Argentine General Corporations Law, a majority of our directors must be residents of Argentina and all directors must 
establish a legal domicile in Argentina for service of notices in connection with their duties. 

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 to constitute a quorum. If a quorum is not met within 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 or call a meeting for another 
day. Resolutions must be adopted by a majority of the directors present (including those connected by video conference), and the 
President or his substitute is entitled to cast the deciding vote in the event of a tie.

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 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, applicable regulations, or by shareholder 
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 is registered with the Superintendency of 
Corporations. 

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 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 interests conflict with ours 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 us. 

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 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 Stock Market Law, as defined in “Item 9. The Offer and Listing Argentine Securities Market,” and Resolution No. 622/2013 of the 
Argentina National Securities Commission (Comision 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. 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, 28, 2017, 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, Luis Augusto Domenech, Emilio José 
Apud and Inés María Leopoldo, as members. Additionally, Mr. Felices was determined by our Board of Directors to be an “Audit

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. From April 2017 
to April 23, 2018 the Audit Committee held 9 formal meetings, regardless of all the working meetings held. 

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

recommendations arising out of its work and the status of the recommendations issued in prior years. 

The Audit Committee supervised the alignment of our internal control system for financial reporting with the requirements established

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.

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.

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 committees 

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 Compensation and Nomination 
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. 

Compensation of members of our Board of Directors and Supervisory Committee 

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 the Supervisory Committee with respect to a fiscal year may not exceed 5% of net income 
for such year if YPF is not paying dividends in respect of such net income, which percentage is increased up to 25% of net 

171 

income based on the amount of dividends, if any, are paid. 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 Supervisory Committee, requires the ratification of 
an ordinary general shareholders’ meeting as provided by Argentine law. When the exercise of special commissions or technical 
administrative functions by one or more directors and the reduced or lack of profits exceed the limits, such remunerations may only be 
paid in excess if expressly agreed by the shareholders’ meeting, for which the matter should be included on the agenda. For the year 
ended December 31, 2017, the aggregate compensation accrued by the members of the Board of Directors and YPF’s executive officers 
for services in all capacities was Ps. 373.3 million, excluding social security payments made by the Company as required by law, but 
including Ps. 43.8 million in the form of equity compensation plans, pensions, retirement or similar benefits that YPF provides to its 
Board of Directors and executive officers and Ps. 4.2 million in compensation paid to the members of the Supervisory Committee. 
During 2017, YPF’s performance-based compensation programs included a performance bonus program for approximately 6,400 
non-unionized YPF employees and 9,000 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 2017, our shareholders’ meeting, as proposed by our Board of Directors, approved the creation of a voluntary reserve of Ps. 
100 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-year terms. 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 2017, the aggregate compensation paid to the members of the Supervisory 
Committee was Ps. 4.2 million. 

The current members of the Supervisory Committee, the year in which they were appointed and the year their current term expires is as 
follows:

Alejandro Fabián Díaz
María Dolores Pujol

Diversity and Inclusion 

President of the Risk and Sustainability Committee

Director for Class A Shares

We know that diversity and inclusion, which make it possible to create a more representative workforce, help to build a more successful 
and profitable company. 

Our people are key in this way. Without their commitment, the company could not develop. That is why we are guided by the 
conviction to respect and value singularity. The will to create opportunities and develop talents. The certainty of promoting inclusion, of 
seeking plurality, of growing in diversity. 

We have taken important steps towards diversity and inclusion. 

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 offices. 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 
Ministry of Labor. An initiative that lasts ten months and gives participants the opportunity to perform qualifying and professionalizing 
practices in different areas of the company with the guidance of a tutor assigned by YPF. 

We believe that one of the bases of inclusion is access to work, that is why we have an Inclusive Procurement Program that facilitates 
access to the network of YPF suppliers to all those organizations, cooperatives, protected workshops, associations and entities 
committed to the employability of people with some physical, sensory or mental disability with skills to create and produce articles of 
aesthetic value, practical utility and / or attractive for the use. Because people with disabilities do not need special help, they 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, 
told us what they think 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. 

These axes were the basis for the definition of actions to remove these obstacles that will be implemented between 2018 and 2020. 

To guarantee equal opportunities, we created a Diversity Committee, with the main objective of leading the implementation of gender 
equality. 

In parallel, the Committee works on the development and presentation of a 5-year plan that includes projects to promote and care for 
diversity and inclusion for our people and for our customers and suppliers. It will also define the strategy for monitoring and evaluating 
results. 

175 

Employee Matters 

Our total workforce consists of permanent and temporary employees. As of December 31, 2015, 2016 and 2017, we had 22,025, 19,257 
and 19,072 employees, respectively. In 2017, the number included 8,506 employees in the Downstream business segment, 3,255 
employees in the Upstream business segment, 1,649 employees in the Gas & Energy business segment and 5,662 employees in the 
Central Administration and Others business segments. We had 813 temporary employees in 2017. The most significant variation in 
2017 included a decrease of employees at YPF Servicios Petroleros S.A, by approximately 220 employees during 2017. Approximately 
45% 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. 

In addition, labor conditions and salaries of third-party employees are represented by sixteen other unions. Approximately 55% 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 45% 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. 

As of December 31, 2017, YPF was a party to approximately 1,024 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, 2017, 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. 

The following table provides a breakdown of our employees by segment as of December 31, 2017.

ITEM 7.

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 following table sets forth information regarding ownership of our capital stock by each person known to us to own beneficially at 
least 5% of our common shares, the Argentine federal and provincial governments and our Employee fund as of April 9, 2018 :

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 to which shares subject to 
expropriation are allocated must enter into a shareholder’s agreement with the federal government which will provide for the

ourselves from certain joint ventures and affiliates (which amounted to Ps. 3.667 million in 2017), as well as what is mentioned in the 
following paragraphs. 

In addition, since the the Expropriation Law (See “Item 4. Information on the Company—Legal and Regulatory Framework and 
Relationship with the Argentine Government—The Expropriation Law.”), the Argentine Republic owns 51% of the shares of the 
Company. Consequently, and in addition to transactions mentioned in the paragraph above, we are party to numerous agreements with 
the federal government, as well as with certain agencies or institutions dependent on such governments and stated-owned companies. 

The information disclosed in Note 31 to the Audited Consolidated Financial Statements disclose the balances with joint ventures and 
affiliated companies as of December 31, 2017, December 31, 2016 and December 31, 2015, and transactions with the aforementioned

Argentine Law Concerning Related Party Transactions 

Section 72 of the Stock Market 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 Stock Market 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 Stock Market 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 (to be 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. 

178 

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, beginning on the 
business day following the day the transaction was approved by the board of directors, the audit committee’s or independent valuation 
firm’s reports 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.

According to data provided by The Bank of New York Mellon, as of April 9, 2018, there were 170,483,216 ADSs outstanding and 
47 holders of record of ADSs. Such ADSs represented approximately 43% of the total number of issued and outstanding Class D shares 
as of such date. The Buenos Aires Stock Market is the principal Argentine market for trading the ordinary shares. 

“BYMA” (Bolsas y Mercados Argentinos) is the largest stock market in Argentina and has been authorized by the CNV to 

delegate certain functions to the Buenos Aires Stock Exchange (“BASE”). Trading on the BYMA is conducted either through the 
traditional auction system from 11 a.m. to 5 p.m. on trading days, or through Millenium, which allows electronic negotiation with 
automatic execution of transactions. Currently, all transactions relating to listed securities can be executed through Millenium result in 
an additional 10-minute successive suspension period. 

Investors in the Argentine securities market are mostly individuals and companies. Institutional investors, which are responsible 

for a growing percentage of trading activity, consist mainly of insurance companies and to a lesser extent mutual funds.

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 Buenos Aires Stock Exchange “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. 

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 Buenos Aires Stock Market (“MERVAL”), which is a stock market authorized 
by the CNV to function as such, under Law No. 26,831. The MERVAL and the BASE have entered into an agreement which has been 
approved by the CNV, whereby the 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 MERVAL and BASE, with each holding initially 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 Caja de Valores S.A., a corporation owned 99.96% by Bolsas y Mercados Argentinos S.A. (“ByMA”) . 
This company 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 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. 

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. 

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. 

182 

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) 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, 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 

183 

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 an 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. 

184 

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 
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”). 

185 

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. 

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 norms governing the collection of proceeds, the legislation applicable to these matters (laws and regulatory 
decrees) and the norms 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” 6060 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” 6094 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 N° 25,246. Any information provided by the UIF 
will be transferred along with the obligation to maintain secrecy pursuant to Article 22 of Law N°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. 

For a more exhaustive analysis of the anti-money laundering regime applicable as of the date of this annual report, it is suggested 

that investors should consult with their legal advisors and read Title XVIII, Book Two of the Argentine Criminal Code, and the 
regulations issued by the UIF, the CNV and the Central Bank, which can be found on the website of the Ministry of Justice and Human 
Rights of Argentina, under the section Legislative Information (www.infoleg.gov.ar), and/or on the UIF’s website (www.uif.gov.ar) 
and/or on the CNV’s website (www.cnv.gov.ar) and/or the Central Bank’s website (www.bcra.gov.ar).

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 and 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 commercial 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 a 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 conditions established. 

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 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. 

187 

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 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. 

A shareholders’ meeting shall be called at least twenty 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. 

188 

Shareholders’ Meetings 

Pursuant to the Argentine 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 take place 
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. We are 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 Corporations Law, such as the approval of our financial statements, allocation of net income 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 Stock Market Law, at ordinary shareholders’ 
meetings, shareholders must consider (i) the disposition of, or creation of any lien over, assets 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 us 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 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 effected 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 notice 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, at which 
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. 

189 

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. We 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 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 N°27/2018—published on January 11, 2018 in the Official Gazette of the Republic of Argentina) 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 us 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 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 those 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 or for such longer period as they may act as replacements. 

Directors hold office from one to three years, as determined by the shareholders’ meetings. As of the General Ordinary and 
Extraordinary Shareholders’ meeting and the Board of Directors’ meeting, both held on April 28, 2017, and the Board of Director’ 
meeting held on February 15, 2018, our Board of Directors is composed of 14 directors and 9 alternates. 

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 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. 

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, 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 aprove the annual budget, expenditure and investment estimates, the necessary borrowing 
levels and the annual action plan of the Corporation. 

190 

Duties and liabilities of Directors 

In accordance with the Argentine 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 o r 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 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 adverse 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 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 Corporations Law, our Board of 
Directors has the right to declare dividends subject to further approval of the shareholders’ meeting. 

After the enactment of the Expropriation Law, at our shareholder’s meeting held on July 17, 2012 a dividend of Ps. 303 million (Ps. 
0.77 per share or ADS) was authorized for payment during 2012. 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 30, 2015, a dividend of Ps. 503 million (Ps. 1.28 per share or ADS) was 
authorized for distribution by December 31, 2015, which was paid in July 2015. 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, 

191 

2017, a dividend of Ps. 716 million (Ps. 1.82 per share or ADS) was authorized and paid in December 2017. On March 2, 2018, the 
Board decided to propose the following to the General Ordinary Shareholders’ Meeting: (i) allocate the sum of Ps. 120 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. 11,020 million to constitute a reserve for investments in the terms of Article 70, third paragraph of the 
General Companies Act No. 19,550 (TO 1984) and its amendments, and (iii) allocate the sum of Ps. 1,200 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, 2018, 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 quarterly 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 Corporations Law and our by-laws, we are 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, our net income is 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 and Supervisory Committee”; 

third, an amount is segregated to pay dividends on preferred stock, if any; and 

fourth, the remainder of net income 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. 

192 

Our Board of Directors submits our 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 income 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 2537 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 we 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 holdings 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 Corporations Law, in exceptional cases and on a case-by-case basis when required for our best interest, 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 our by-laws, we 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 Stock Market 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 Corporations Law, if authorized by an extraordinary shareholders’ meeting, companies 
authorized to make public offering of their securities, such as us, may shorten the period during which preemptive rights may be 
exercised from 30 to ten 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 unpreempted shares, in accordance with the following procedure: 

• Any unpreempted 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 unpreempted 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 D shares. 

193 

• Any unpreempted 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 unpreempted 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. 

194 

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 us of such acquisition within five days of such acquisition, 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 and 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 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 (collectively, an “Offeror”), would own or control 
shares that, combined with such Offeror’s prior holdings, 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” below. 

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 our outstanding shares and convertible securities. The Offeror will be required to provide us 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”). We 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 our 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. 

Our Board of Directors shall call a special meeting of the holders of Class A shares to be held ten 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 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)

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 us, 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 us, subject to certain antidilution adjustments; 

195 

(iii)

(iv)

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 
us 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 us in the two-year period immediately preceding the date of the notice provided to 
us, in each case determined in accordance with standard practices in the financial community. 

Any 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, plus an additional period of a minimum of five days and a maximum of ten days required by 
CNV regulations, 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 us 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)

(iv)

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 as adjusted for any stock split, reverse stock split, stock dividend 
or other reclassification affecting the Class; 

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, 
adjusted as described above; 

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 as adjusted as described above; and 

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 us 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. 

Material Contracts 

None.

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, 
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. 

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. 

197 

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 4% to 21.925%, 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 
Kingdom and Uruguay. The tax treaty between Argentina and the United Arab Emirates has been signed, but the treaty has not yet been 
ratified by their respective governments. The new tax treaty between Argentina and Mexico was ratified by their governments and went 
into effect as of January 1, 2018. 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. 
As of the date of this annual report, this law has not been regulated by the Executive Branch. 

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. 

198 

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. 

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 of the tax considerations that may be relevant to a particular 
person’s decision to hold such securities. 

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:

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. 

199 

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 analysis of 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. 

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 non-corporate U.S. dividends paid by qualified foreign corporations to certain non-corporate U.S. Holders are 
taxable at a reduced rate if they are “qualified dividend income”. Dividends paid on the Class D shares or ADSs will be treated as 
qualified dividend income if (i) the Class D shares or ADSs are readily tradable on an established securities marked 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 PFIC (Passive foreign investment company). Some 
non-corporate U.S. Holders may also be subject to a 3.8% net investment surtax. 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 applicable limitations (including a minimum holding period requirement) that may vary depending upon your circumstances 
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. 

200 

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) may be eligible for preferential rates of U.S. federal income tax in respect of longterm capital gains. The deductibility of 
capital losses is subject to limitations under the Code. 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. 

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 2017 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 (including, among other things, less than 25 percent owned equity 
investments) 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 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 Internal Revenue Service. 

Certain U.S. Holders may be required, generally on Internal Revenue ServiceForm 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.

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, 2017, 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. 

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 18.4% considering the period-end exchange rates for U.S. 

dollars as of December 31, 2017 and 2016. 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 
income 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 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 Annex iii to our Audited Consolidated Financial Statements. 

Interest rate exposure 

The table below provides information about our assets and liabilities as of December 31, 2017 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, 
2017, see “Item 4. Information on the Company—Exploration and Production—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. 

203 

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. 

In 2017, the Depositary made no direct or indirect payments to YPF.

Controls and Procedures 

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures 

As of December 31, 2017, 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 Chief Financial Officer concluded that there was reasonable 

assurance that the design and operation of these disclosure controls and procedures were effective as of December 31, 2017, 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. 

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, 2017. 

Our internal control over financial reporting as of December 31, 2017 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. 

Changes in Internal Control Over Financial Reporting 

There were no changes in the YPF’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange 

Act) that occurred during the period covered by this annual report on Form 20-F that have materially affected, or are reasonably likely 
to materially affect our internal control over financial reporting. 

ITEM 16.

ITEM 16A.

Audit Committee Financial Expert 

Our Board of Directors determined that Carlos Alberto Felices is the Audit Committee Financial Expert at the meetings held on on 

April 29, 2016 and April 28, 2017. YPF believes that Mr. Felices possesses the attributes of an Audit Committee Financial Expert set 
forth in the instructions to Item 16A of Form 20-F. Mr. Felices is an independent director. 

ITEM 16B.

Code of Ethics 

YPF has adopted a Code of Ethics and Conduct (“Code of Ethics”) applicable to the Board of Directors, all YPF employees, 
contractors, sub-contractors, vendors, suppliers and business partners conducting business with YPF, which was most recently amended 
effective August 8, 2017. The amendment introduced a new value to the Code of Ethics regarding gender equality. Since August 15, 
2003, we have not waived compliance with the Code of Ethics. YPF undertakes to provide to any person without charge, upon request, 
a copy of such Code of Ethics. 

The Code of Ethics establishes the implementation of an ethics hotline to receive complaints regarding the lack of fulfilment of the 

Code of Ethics, an Ethics Committee that will consider complaints received, the appointment of an Ethics Officer who will conduct 
pertinent investigations, the incorporation of a policy on prohibited periods for trading YPF securities to be followed by officers and 
those others to whom the Code of Ethics is applicable when conducting stock transactions, among other requirements. 

Ethics Committee

The Board of Directors created the Ethics Committee, which is in charge of implementing the Code of Ethics and Conduct of 
YPF, and assessing and establishing the actions required to address the reported situations. It also supervises YPF’s “Ethics Line”. It is 
composed of five members, three of which shall serve as Internal Auditor, Legal Affairs Corporate Vice-President and Human 
Resources Vice-President, while the other two will be appointed by the Chairman of the Board of Directors of YPF S.A. from among 
employees which perform in operative or business areas. As of the date of this annual report, the Ethics Committee is composed of the 
following members: Javier Fevré (Internal Auditor) Germán Fernánez Lahore (Legal Affairs Corporate Vice President) , José Manuel 
Aggio (Human Resources Vice President), Marcos Browne (Gas and Energy Executive Vice President) and Carlos Alfonsi (Operations 
and Transformation Executive Vice President ).

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, 2017, 2016, and 2015, the related consolidated 
statements of comprehensive income, changes in shareholders’ equity, and cash flow, for each of the three years in the period ended 
December 31, 2017, 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, 2017, 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, 2017, 2016 and 2015, and the results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2017, 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, 2017, 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.

As of December 31, 2017, the Group carries out its transactions and operations in accordance with the following structure: 

• Upstream; 

• Gas and Power; 

• Downstream; 

• Central administration and others, which covers the remaining activities not included in the previous categories.

2. 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, 2017 are presented in accordance with IFRS, as 
issued by IASB. 

Additionally, some additional issues required by the LGS and/or CNV’s regulations have been included. This information is contained 
in the Notes to these consolidated financial statements, with the purpose of fulfilling regulatory requirements. 

The amounts and other information corresponding to the years ended on December 31, 2016 and 2015 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 2, 
2018. Additionally, see Note 34. 

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. 

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. Actual future results might differ from the estimates and assessments made at the date of preparation of 
these consolidated financial statements.

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

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 in which the Group holds control. 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 exclusively, obtained by the ownership, direct or indirect, of more than 50% of the voting shares of a 
company. 

Interest in JO and other agreements which give 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 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, on a pro rata consolidation basis. 

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 in which 
YPF holds control, taking into consideration, where necessary, 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 

IAS 29 “Financial reporting in hyperinflationary economies” requires the financial statements of an entity whose functional currency is 
that of a hyperinflationary economy to be expressed in terms of the current measurement unit as of the closing date of the reporting 
fiscal year, regardless of whether they are based on the historical cost method or the current cost method. For such purpose, in general 
terms, inflation that has occurred from the date of acquisition or from the revaluation date, as appropriate, is to be computed in 
non-monetary items. In order to conclude on the existence of a hyperinflationary economy, such standard describes in detail a number 
of quantitative and qualitative factors to be taken into account including an accumulated inflation rate during a three–year period that 
amounts to or exceeds 100%. 

As of December 31, 2017, taking into account the decreasing inflation trend, the inconsistency of the published inflation data in 
previous years, and the fact that the rest of the indicators do not lead to a definitive conclusion, the Management of the Company 
understands that there is not enough evidence for Argentina to be considered a country with a hyperinflationary economy. This 
conclusion is in line with that expressed by the International Practices Task Force of AICPA (“American Institute of Certified Public 
Accountants”) which did not consider Argentina as a country with a hyperinflationary economy. Therefore, the criteria for restatement 
of information established under IAS 29 in the current year have not been applied.

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

However, in recent years, certain macroeconomic variables affecting the business of these companies, such as wages, prices of main 
raw materials and inputs and services, have undergone variations of some importance. This circumstance must be considered in the 
evaluation and interpretation of the financial condition and the results of these companies in the financial statements. 

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 
cancellation, 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 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 at 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. 

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. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

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. 

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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2017, 2016 AND 2015

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

Impairment of financial assets 

The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or group of financial 
assets measured at amortized cost is impaired. Impairment losses are recognized only if there is objective evidence of impairment 
because of one or more events that occurred after the initial recognition of the assets and such impairment may be reliably measured. 

Evidence of impairment includes indications that a debtor or a group of debtors are experiencing significant financial difficulty, default 
or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganization, and 
when observable information indicates that there is a measurable decrease in the estimated future cash flows. 

The impairment amount is measured as the difference between the asset’s carrying amount and the present value of estimated future 
cash flows (excluding future credit losses that have not been incurred), discounted at the financial asset’s original effective interest rate. 
The carrying amount of the asset is reduced and the amount or the loss is recognized in the statement of comprehensive income. For 
practical purposes, the Group may measure impairment based on an instrument’s fair value, using an observable market price. If, in a 
subsequent period, the amount the impairment loss decreases and the decrease can be related objectively to an event occurring after the 
impairment was recognized, the reversal of the previously recognized impairment loss is recognized in the statements of comprehensive 
income. 

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 of 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. 

F-14 

YPF SOCIEDAD ANONIMA
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2017, 2016 AND 2015

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

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. 

In connection with the foregoing, the Privatization Law granted the Company 35-year transportation concessions for the 
transportation facilities operated by Yacimientos Petrolíferos Fiscales 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 at Management of the Company’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 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.

AS OF DECEMBER 31, 2017, 2016 AND 2015

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

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, 2017, 2016 and 2015. 

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 “Result from 
participation 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%. 

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 “Result from participation 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. 

As from the effective date of Law No. 25,063, dividends, either in cash or in kind, that the Group receives from investments in other 
companies and which are in excess of the accumulated income that these companies carry upon distribution will be subject to a 35% 
income tax withholding as a sole and final payment. The Group has not recorded any charge for this tax since it has estimated that 
dividends from earnings recorded by the equity method will not be subject to such tax. However, according to of the aforementioned 
Argentine Tax Reform Law No. 27,430, this tax is eliminated for income accrued as of 2018 (see Note 30.l).

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

Years of Estimated
Useful Life

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.

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

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 on a field-by-field basis or other external available information if abandonment obligations were not 
performed. 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. 

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. 

Provisions are measured at their current value of cash flows estimated to satisfy the obligation, applying a pre-tax rate that reflects the 
market valuations of the time value of money and the specific risks of the obligation. The increase in the provision due to the passage of 
time is recognized in the statement of comprehensive income. 

When a contract qualifies as onerous, the related unavoidable liabilities are recognized in the consolidated financial statements as 
provisions, net of the expected benefits. 

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.

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

• CGU Oil; 

• CGU Gas – Neuquina Basin; 

• CGU Gas – Noroeste Basin; 

• CGU Gas – Austral Basin; 

As of December 31, 2016, there were the Gas UGE—Neuquina Basin—YSUR and UGE Gas—Austral Basin—YSUR, which after the 
operative merger of the YSUR Group with YPF, were incorporated to the UGE Gas—Neuquina Basin and UGE Gas—Austral Basin, 
both of YPF. 

As of December 31, 2015, the Petroleum CGU—YPF Holdings, was in existence; however, such CGU was deconsolidated during fiscal 
year 2016. 

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 Note 3. 

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 AESA CGU, which primarily comprises the assets used for construction purposes related to the activities of the 
subsidiary. 

This aggregation is the best reflection of how the Group currently makes its management decisions for the generation of separate cash 
flows of the assets. 

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 capital cost 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 use value, based on expected future cash flows from the use of such assets, discounted at a rate that 
reflects the weighted average cost of the allocated principal amount, 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.

AS OF DECEMBER 31, 2017, 2016 AND 2015

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

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.

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

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 

General criteria 

Revenue is recognized on sales of crude oil, refined products and natural gas, in each case, when title and risks are 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. 

Revenue recognition related to Government incentive programs 

Incentives for the additional injection of natural gas and for the production of crude oil granted by the Planning and Strategic 
Coordination Commission of the National Plan of Hydrocarbons Investment by Resolutions No. 1/2013 and No. 14/2015, respectively 
(see Note 30), fall within the scope of the IAS 20 “Accounting for Government grants and disclosure of government assistance”, 
because they constitute economic compensation for the companies committed to increasing their respective production. Incentives have 
been included in “Revenues” in the consolidated statement of comprehensive income. 

Likewise, these regulations also apply to the temporary economic assistance by Metrogas (see Note 30), as enacted by the MINEM 
under Resolution No. 312-E/1016 and by the former Argentine Energy Secretariat under Resolution No. 263/2015, as its purpose is 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 is concluded. The incentives have been included in the 
item “Other net operating results” in the consolidated statement of comprehensive income. 

In addition, Argentine tax authorities provide a tax incentive for investment in capital goods, computers and telecommunications for 
domestic manufacturers 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 No. 379/2001, 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 this income is made at its fair value when there is a reasonable certainty that incentives will be received and that 
regulatory requirements related therewith have been fulfilled.

Recognition of revenues and costs associated with construction contracts method 

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.

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 has not entered into any significant leases with third parties. 

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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2017, 2016 AND 2015

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

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 and loans. 

2.b.15) Taxes, withholdings and royalties 

Income tax and tax on minimum presumed income 

The Group recognizes income tax applying the liability method, which considers the effect of temporary differences between the 
financial and tax bases of assets and liabilities and the tax loss carry forwards 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. 

According to the latest amendments introduced by the Argentine Tax Reform Law No. 27,430 published in the Official Gazette on 
December 29, 2017 (see Note 30.l), the general tax rate is reduced from 35% currently in force 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 accrued as of December 31, 2017, 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 tax 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 
35% 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. 

In relation to the minimum presumed income tax, it is worth mentioning that it was overruled for the years beginning on January 1, 
2019, as established by Law No. 27,260.

Under Law No. 25,063, dividends distributed, either in cash or in kind, in excess of accumulated taxable income as of the end of the 
year immediately preceding the dividend payment or distribution date, will be subject to a 35% income tax withholding as a sole and 
final payment, except for those distributed to shareholders residing in countries benefited from treaties for the avoidance of double 
taxation, which will be subject to a minor tax rate. However, according to the aforementioned Tax Reform Law No. 27,430, this tax is 
eliminated for those incomes accrued as of 2018 (See Note 30.l). 

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 will apply 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. In addition, and 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). 

Royalty expense and extraordinary production royalties are accounted for as a production cost. 

2.b.16) Shareholders’ equity accounts 

Shareholders’ equity accounts have been valued in accordance with accounting principles in effect as of the transition date. The 
accounting transactions that affect shareholders’ equity accounts were accounted for in accordance with the decisions taken by the 
Shareholders’ meetings, and legal standards 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 Argentine 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 in constant peso (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, 2017, 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. 

Reserve for investments and reserve for purchase of treasury shares 

Corresponds to the allocation made by the YPF’s Shareholders’ meeting, whereby a specific amount is being assigned to be used in 
future investments and in the purchase of YPF’s shares to meet the obligations arising from share-based benefit plan described in Note 
2.b.10.iii). 

Initial IFRS adjustment reserve 

Corresponds to the initial adjustment in the transition to IFRS application, which was approved by the Shareholders’ meeting of 
April 30, 2013, in accordance with the General Resolution No. 609 of the CNV. 

Such reserve may not be used in distributions in cash or in kind to the shareholders or owners of YPF and may be reversed only for 
capitalization or absorption of an eventual negative balance on the “Retained earnings” account according the aforementioned 
Resolution. 

Such reserve was disaffected in the fiscal year ended December 31, 2017. See Note 25. 

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 as of December 31, 2017, the Group did not used derivative financial 
instruments. During the fiscal years ended December 31, 2016, and 2015, the Group has not applied hedge accounting to its derivative 
financial instruments. Gains or losses from these derivative financial instruments are classified as “Net financial results”, in the 
statement of comprehensive income. 

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. 

During the fiscal year ended December 31, 2017, the Group did not use derivative financial instruments. During the fiscal years ended 
December 31, 2016 and 2015, the Group only used derivative financial instruments traded on active markets (futures contracts in 
dollars). 

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. 

A provision for bad debt is created where there is objective evidence that the Group may not be able to collect all receivables within the 
original payment terms. Indicators of bad debts include significant financial distress of the debtor, the debtor potentially filing a petition 
for reorganization or bankrupt, or any event of default or past due account. 

In the case of larger non-homogenous receivables, the impairment provision is calculated on an individual basis. When assessed 
individually, the Group records a provision for impairment which amounts to the difference between the value of the discounted 
expected future cash flows of the receivable and its carrying amount, taking into account existing collateral, if any. This provision takes 
into consideration the financial condition of the debtor, the resources, payment track record and, if applicable, the value of collateral. 

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”. Subsequent recoveries of amounts previously written off are also 
credited against “Selling expenses” in the statement of comprehensive income. 

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. 

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 (that is, a disposal of the Group’s entire interest in a foreign operation, or a disposal involving 
loss of control over a subsidiary that includes a foreign operation), 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 are 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 at 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 

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 these assets (or groups of assets) 
and such transaction must be highly probable. 

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.

Noncurrent 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 the closing of these consolidated financial statements, the Group classified the investment in the subsidiary YPF EE as an asset 
held for disposal. See Note 3. 

2.b.25) New standards issued 

As required by IAS 8“Accounting policies, changes in accounting estimates and errors”, we detail below 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. 

Those standards or interpretations issued by the IASB, the application of which is mandatory as of the closing date of these consolidated 
financial statements, have been adopted by the Group, if applicable. 

•

Amendments to IAS 7—Information disclosure initiative 

In January 2016, the IASB amended IAS 7 and such amendments are to be applied to fiscal years beginning on or after January 1, 2017, 
though they may be implemented in advance. 

The Disclosure Initiative was amended for the purpose of disclosing information that allows users of financial statements to evaluate the 
changes in liabilities (and certain assets) that have occurred during a period, derived from financing activities. 

The explanation for the changes must differentiate those “changes from cash flows deriving from financing” from those “changes other 
than cash”. 

Also, when explaining changes other than cash, the following sources of changes should be differentiated, to the extent necessary to 
meet the purpose: (i) changes resulting from the acquisition or loss of control of subsidiaries and other businesses; (ii) the effect of 
foreign exchange rate changes; (iii) changes in fair value; and (iv) other changes (by separately identifying any variance deemed 
relevant). 

The IASB defines liabilities arising from financing activities as liabilities “for which cash flows were or will be classified in the 
statement of cash flows as cash flows deriving from financing activities”. Additionally, it emphasizes that new disclosure requirements 
also relate to changes in financial assets (for example, assets covering liabilities arising from financing activities) if they meet the same 
definition. 

Finally, the amendments set forth that changes in liabilities arising from financing activities must be disclosed separately from changes 
in other assets and liabilities. 

The adoption of such amendments did not have any effects on the Group’s consolidated financial statements. 

•

Amendments to IAS 12—Recognition of deferred tax assets for unrealized losses 

In January 2016, the IASB amended IAS 12 and such amendments are to be applied to fiscal years beginning on or after January 1, 
2017, though they may be implemented in advance. 

The amendment to IAS 12 provides that when an entity assesses whether the taxable profit against which a deductible temporary 
difference may be available, it will consider whether the tax legislation restricts the sources of taxable income against which it may 
make deductions at the time of the reversal of that temporary deductible difference. If the tax law does not impose those restrictions, an 
entity will evaluate a deductible temporary difference in combination with all others. However, if the tax law restricts the use of losses 

to be deducted against income of a specific type, a deductible temporary difference will be evaluated in combination only with the 
appropriate rate. 

The adoption of the foregoing modifications did not have any effects on the consolidated financial statements of the Group.

Amendments to IFRS12 – Disclosure of interests in other entities 

The amendment made in compliance with the annual improvements to IFRS 2014-2016, applicable to those fiscal years beginning on or 
after January 1, 2017, introduces a change in the scope of this standard, considering that an entity does not need to provide summarized 
financial information for those equity interests in subsidiaries, associates or joint ventures which are classified (or included in a the 
held-for-sale group which is classified) as held for disposal. The amendments clarify that this is the only concession of the disclosure 
requirements of IFRS 12 for such equity interests. 

The adoption of the foregoing modifications did not have any effects on the consolidated financial statements of the Group. 

Standards or interpretations issued by the IASB, the application of which is not mandatory as of the closing date of these consolidated 
financial statements and which, therefore, have not been adopted by the Group. 

•

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. 

•

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, based on the analysis of the Group’s financial assets and liabilities as of December 31, 
2017, and based on the facts and circumstances that exist on that date.

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. 

During fiscal year 2017, the Group has analyzed the calculation model of the impairment of its commercial loans and other 
receivables, based on the simplified approach indicated by such standard. Moreover, it has evaluated the necessary changes in the 
systems and processes to record the expected credit losses, since until now the calculation contemplated the impairment due to the 
incurred loss. 

The Group has prepared a matrix, based on certain special characteristics indicating the ability to repay the loan, such as i) 
payments in arrears, ii) existence of guarantees, iii) existence of a legal proceeding, among others; and it has also assigned an 
expected uncollectibility rate based on historical default rates adjusted to future economic conditions. 

After the analysis, the Group considers that the application of the model will not have a significant effect on the financial 
statements for the fiscal year beginning on January 1, 2018. 

• 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 Group does not anticipate that the application of this part of the standard will have a significant effect on its financial 
statements because it has not carry out this type of transactions at the end of the fiscal year ended December 31, 2017. 

Additionally, during October 2017, a modification related to the early cancellation with negative compensation was introduced, for 
which the lender (i.e., the holder) could be forced to accept the payment for the early cancellation, of an amount substantially less than 
the unpaid amounts of principal and interest. In these cases, the amendment proposes that financial assets with these characteristics be 
measured at amortized cost or at fair value with changes in other comprehensive income. 

The Group estimates that the application of this latest amendment, effective as of January 1, 2019 with the possibility of being applied 
before such date, will not have a significant effect on its financial statements because it has not carried out transactions with these 
characteristics. 

•

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).

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2017, 2016 AND 2015

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

IFRS 15 establishes an extensive and detailed model to be used by entities at the time of accounting for income from contracts entered 
into with their customers. It will replace the following Income Standards and Interpretations after the effective date: 

•

•

•

•

•

•

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. 

As stated in the heading of the new income standard, IFRS 15 will only cover income from contracts entered into with clients. Under 
IFRS 15, a customer of an entity is a party that has executed a contract with such entity for the provision of goods and services that are 
the product of ordinary business activities in exchange for consideration. Unlike the scope of the IAS 18, the recognition and 
measurement of income from interest and dividends on the debt and investments in shareholders’ equity are not contemplated under the 
scope of IFRS 15. Conversely, they are contemplated under the scope of IAS 39 “Financial Instruments: Recognition and 
Measurement” (or IFRS 9 “Financial Instruments”, if such IFRS is adopted in advance). 

As mentioned above, the new income standard relies upon a detailed model to explain income from contracts entered into with 
customers. Its fundamental principle is that an entity should recognize income 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 those goods or services. 

The new income recognition standard adds a five-step approach to income recognition and measurement: 

1. Identify the contract entered into with the customer. 

2. Identify the separable obligations of the contract. 

3. Determine the transaction price. 

4. Allocate the transaction price between the obligations of the contract. 

5. Recognize the income when the entity meets the obligations. 

The new revenue standard has introduced many indications that are more prescriptive: 

•

•

If the contract (or combination of contracts) contains or does not contain more than one of the promised goods or services 
and, if so, when and how the goods or services should be delivered or provided. 

If the transaction price distributed to each performance obligation should be recognized as income over time or at a specific 
time. Under IFRS 15, an entity recognizes income when the obligation is satisfied, that is, when the control of the goods and 
services underlying a particular obligation is transferred to the customer. Unlike IAS 18, the new model does not include 
separate guidelines for the “sale of goods” and the “provision of services”; instead, it requires entities to assess whether 
income should be recognized over time or at a specific time, regardless of whether such income includes “the sale of goods” 
or “the provision of services”. 

• When the transaction price includes an element of estimation of variable payments, the way in which it will affect the 

amount and the time for the recognition of the income. The concept of variable payment estimation is broad. A transaction 
price is considered as a variable for discounts, refunds, credits, price concessions, incentives, performance bonds, penalties 
and contingency agreements. The new model introduces a material condition for variable consideration to be recognized as 
income: only until it is very unlikely that a significant change in the amount of accumulated income will occur when the 
uncertainties inherent in the variable payment estimate have been resolved. 

• When the execution costs of an agreement and the performance costs thereof may be recognized as an asset.

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

During fiscal year 2017, the Group has carried out tasks aimed at a preliminary evaluation of the impact generated by the application of 
this standard. In this process, the unique model of five-step income recognition, described in previous paragraphs, has been taken as the 
basis for analysis, and it has been applied to the following main income from contracts with customers: 

• Contracts for the sale of fuels under the consigned pattern; 

• Contracts for the direct sale of fuels; 

• Contracts for the sale of natural gas; 

• Contracts and sales agreements of other refined products; 

• Construction contracts. 

In the first four types of contracts, related to the sale of goods, income is recognized when ownership and risks of the goods are 
transferred to the customer. Even in the case of contracts under the consigned pattern, income is not recognized until the good is sold to 
the intermediary’s customer. It is emphasized that in these contracts there are no separate performance obligations nor any obligations 
other than the delivery of goods. 

In the case of the construction contracts, income 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 the physical progress thereof. In this type of contract, 
there are performance obligations that are fulfilled over time. 

From such analysis, 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; (iv) the accrual of income accounts; with respect to the income recognition criteria that are being applied and 
which are described in the foregoing paragraphs. 

On the contrary, in accordance with the introduced requirements the need has been identified to make new dissagregations of the 
information to be disclosed. To such effect, the Group has evaluated to make such dissagregations based on the analysis carried out by 
the Board of Directors on this item; consequently, it is expected that a breakdown of the income reported in note 19 will be incorporated 
by (i) type of good or service and target market, and (ii) sales channels. In addition, the Group has reviewed and adapted its 
information, management and reporting systems. 

•

IFRS 16—Leases 

IFRS 16 is in effect for reporting periods beginning on January 1, 2019 and its implementation in advance is permitted for entities that 
use IFRS 15 “Revenue from ordinary activities from contracts entered into with customers” prior to the date of initial application of 
IFRS 16. 

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 accounting of tenants. It will replace the following Standards and Interpretations after 
the effective date thereof: 

•

•

•

•

IAS 17 “Leases”; 

IFRIC 4 “Determination whether an agreement contains a lease”; 

SIC 15 “Operating leases-incentives”; and 

SIC 27 “Evaluating the substance of transactions involving the legal form of a lease”. 

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 enjoyed 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 new leasing rule has introduced many other prescriptive indications: 

• Measurement of the asset by right of use 

The cost of the right to use the assets includes the following items: 

(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 
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 to use the 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 

A lessee will measure the lease liability 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 incremental rate for the lessee’s loans. 

Lease liabilities must include the following items: 

(a)

(b)

(c)

(d)

(e)

fixed payments (including essentially 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 exercise price of a call 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 be increasing the liability for the lease to reflect the accrued interest (and recognized in 
the profit and loss account), 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” installments.

• Revision of the lease liability 

The lessee must review the lease liability in the following cases: 

(a)

(b)

(c)

when there is a change in the amount expected to be paid under a residual value guarantee; 

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); 

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 call option of the underlying asset. 

•

Lessor’s accounting 

IFRS 16 requires the lessor to classify the lease as operational or financial. 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. 

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. 

•

Sale and Leaseback Transactions 

This type of transaction is dealt with from the point of view of the lessee-seller as lessor-buyer. The fundamental aspect of 
dealing with such transactions depends on whether the transfer of the relevant asset meets the criteria of IFRS 15 “Revenue 
from contracts with customers”, to be recognized as a sale. 

The Group is still in the process of assessing the full impact of the IFRS 16 application on its financial statements and does not intend to 
apply such standard in advance. 

• 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 Group does not anticipate that the application of the amendments to the standard will have a significant effect on its financial

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 Group does not anticipate that the application of the interpretation of the standard will have a significant effect on its financial

Annual improvements to IFRS –2014 – 2016 Cycle 

In December 2016, the IASB issued the annual improvements 2014 – 2016, which are applicable to fiscal years beginning on or after 
January 1, 2018, though they may be implemented in advance. 

Standard
IFRS 1 “First-time 
Adoption of International 
Financial Reporting 
Standards”

Amended Subject
Elimination of short-
term exemptions for 
first-time adopters of 
IFRS.

IAS 28 “Investments in 
associates and joint 
ventures”

Measurement at fair 
value of an associate or 
joint venture.

Detail

The amendment introduces the deletion of paragraphs that consider the limited 
exemption of comparative disclosure from IFRS 7 for first-time adopters of 
IFRS, disclosures of transfers of financial assets and paragraph 39AA considered 
the annual best improvements to IFRS 2014-2016 Cycle.

The amendment introduces changes in relation to the exemption and the 
procedures to be applied to the equity method, clarifies that an entity will apply 
this exemption or the method separately to each associate or joint venture, in the 
case of exemption in the initial recognition of the associate or joint venture, and 
with respect to the method on a date that is the later of: a) when the associate or 
joint venture that is an investment entity is initially recognized; b) when the 
associate or joint venture becomes an investment entity; or c) when the associate 
or joint venture that is an investment entity becomes a parent company.

The Group does not anticipate that the application of the amendments to the standard will have a significant effect on its financial

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 Group does not anticipate that the application of the amendments to the abovementioned standards will have a significant effect on 
its financial statements. 

•

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 return. 

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 return. 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 is in the process of evaluating the impact of this modification on its financial statements. 

•

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. It is recommended to apply this modification simultaneously with the application of IFRS 9 for the first 
time. 

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 the financial 
statements of the Company.

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
IFRS 3 “Business 
Combinations” and IFRS 
11 “Joint arrangements”

Amended Subject
Holdings previously 
held in a joint operation

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 reasonable 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 the effect 
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 “Loan Costs”

Capitalization of 
generic loans

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 does not anticipate that the application of the amendments to the mentioned standards will have a significant effect on its 
financial statements. 

•

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 Group does not anticipate that this standard will have effects on its financial statements, because of not providing this type of 
services.

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 and 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 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 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 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, 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 stated 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. 

With regard to the analysis of prior periods until recently, 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. 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 (which evidenced a substantial reduction since mid-2014), all of which caused a gradual 6% 
reduction in the prices of sales of Medanito and Escalante crude oil on the local market (2% monthly as of August 2016). 

Likewise, in January 2017, Producers and Refiners reached a new agreement for the transition referred to above, 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. As stated above, this readjustment of prices in the domestic market and other 
signs that aimed at a convergence with international prices in the near future, coupled with a decline in the prices expected in the 
medium term compared to the estimates existing as of December 31, 2015, were considered as evidence of impairment of the value of 
the assets of the CGU Oil in the fiscal year ended December 31, 2016. 

Based on the aforementioned methodology, the expected decrease in the 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 and 2,361 as of December 31, 2016 and 
2015, respectively. The CGU Oil recoverable value after taxes as of December 31, 2016 and 2015 was 71,495 and 76,829 respectively. 

In addition, as of December 31, 2015, the Group had recorded a charge for impairment of property, plant and equipment, with respect to 
the CGU Oil—YPF Holdings, which grouped the assets of the crude oil production fields in the United States which amounted to 94, 
due to a decline in international crude oil prices. The fair value of the CGU Oil—YPF Holdings amounted to 179. The Group also 
recorded an impairment charge of intangible assets of 80 related to rights in exploratory areas whose recoverable value was zero. 
During the fiscal year 2016, this CGU was deconsolidated.

2. BASIS OF PREPARATION OF THE CONSOLIDATED FINANCIAL STATEMENTS (Cont.) 

Considering what has been mentioned in the previous paragraphs, and in terms specifically of prices according to the expected new 
behavior of the domestic fuel market (import / export parity), as of December 31, 2017 the expected future cash flows were determined 
using the estimated future prices, which are based on a forecast thereof made by the Group, which takes into account multiple forecasts 
or independent estimates. Additionally, prices do not scale to levels that exceed historical market prices observed in the past, applied to 
projected future production volumes. Moreover, the projected and estimated production volumes for estimating the cash flow are based 
on the oil and natural gas estimates made at the end of the period. 

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 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.

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 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, 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. As indicated above, at the end of 2017, Management of the Company does not see 
any significant changes in the long-term price curves, given that it does not consider recent (positive) changes in commodity prices, 
taking into account the high observed volatility, and until the variables that impact them demonstrate a certain stability over time. The 
recoverable value as of December 31, 2017 of the CGU Oil, after taxes, was 82,802. 

2.d) Comparative Information 

Balance items as of December 31, 2016 and 2015 presented in these financial statements for comparison purposes arise from the

As a result of this process, the Group reflects the investment in YPF EE in its consolidated financial statements as of December 31, 
2017 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). 

According to IFRS 5, assets and liabilities held for disposal must be valued at book value or fair value less costs of the transaction, 
whichever is lower. 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 nor has it been 
recorded as of December 31, 2017. 

Although YPF EE represents a component within YPF because it is an individual CGU within the Gas and Energy segment, it does not 
qualify as a discontinued operation since it does not represent a significant line of business nor a geographical area.

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 will jointly control YPF EE Consequently, 
the Group will apply IFRS 11 “Joint Arrangements” defining such company as a joint venture, and will assess it according to the equity 
method under the IAS 28 “Investments in associates and joint ventures”, once the transaction has been concluded. 

Some of the main evaluated assumptions are described below: 

(i) Any decisions about the relevant activities thereof are to be taken jointly, there being no power of one shareholder over the 
other in relation to the investment, regardless of the different percentages of equity interests held by each of them. Although 
the Group will own a 75% stake in YPF EE, according to the shareholders’ agreement, the approval of at least one Director 
appointed by each class of shares at the meeting of the Board of Directors or the approval of the full class of shares at the 
meeting of Shareholders is required for decision-making purposes regarding the relevant activities; 

(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.

Assignment of the Cerro Bandera area 

YPF and Oilstone Energía S.A. (“OESA”) entered into an agreement for the assignment of 100% of the exploitation concession of the 
Cerro Bandera area in the province of Neuquen (the “Concession”) on November 22, 2017. It should be noted that OESA operates the 
block since 2011 under the respective operating Agreement subscribed with YPF. 

The agreement considers the assignment of the Concession for US$14 million. Moreover, the agreement sets forth that YPF maintains 
rights, under certain terms and conditions, to (i) the Vaca Muerta and Molles formations, in which it may continue to carry out 
exploration and potential exploitation works; and (ii) an exploratory project in the northern region of the Concession, and its potential 
exploitation. 

The entry into force of the assignment is subject to compliance with certain conditions precedent, which must be met before May 22, 
2018. The above conditions mainly refer to the authorization of the assignments of participation provided in the assignment Agreement 
by the Executive Branch of the Province of Neuquén.

Assignment of equity interest in the Aguada de la Arena area 

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 equity interests 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 equity interests in the operating concessions between YPF and PESA was consummated, as 
follows: (i) an equity interest of 33.33% in the Río Neuquén area for the sum of US$ 72 million; and (ii) an equity 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 equity interests in the Aguada de la Arena area for US$ 18 million. Thus, YPF increased its participation to 100% in the

4. FINANCIAL RISK MANAGEMENT 

The Group’s activities involve various types of financial risks: market risk (including exchange rate risk, interest rate risk and price 
risk), credit risk and liquidity risk. The Group maintains an organizational structure and systems that allow the identification, 
measurement and control of the risks to which it is exposed. 

• Market Risk 

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 Argentine peso (the Argentine legal currency). 

The Group does not use derivatives as a hedge against exchange rate fluctuations. While during fiscal year 2015 the Group started to 
operate with U.S. dollars future exchange rate agreements (until their complete termination in fiscal year 2016), for IFRS 7“Financial 
instruments: disclosures” no exchange rate risk arises from financial instruments denominated in the Company’s functional currency. 

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, 2017:

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 expenses 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.

4. FINANCIAL RISK MANAGEMENT (Cont.) 

The variable rate financial loans represent 22% of the total loans as of December 31, 2017, 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 31,500 accrues variable interest of BADLAR plus a 
spread between 0% and 6% and 8,509 accrues variable interest of LIBOR plus a spread between 1.4% and 7.5%. 

Approximately 77% (146,353) of the total of the financial loans of the Group is denominated in U.S. dollars, 3% (5,785) is in Swiss 
francs and the remainder is mainly in Argentine pesos, as of December 31, 2017. 

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 placingfunds 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 floating 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 comprehensive income that an increase or decrease of 100 basis points in 
the interest rate would have.

Other Price Risks 

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. Additionally, the Group was impacted by certain regulations that affected the determination of export prices received 
by the Group, such as those mentioned in Note 30, which consequently limits the effects of short-term price volatility in the 
international market. 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, as mentioned above, 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 crudes (Medanito and Escalante). In the same way, in 
January 2017, the Producers and Refiners entered into a new agreement for the above mentioned transition, in which a range of prices 
was established for the sale of oil on the domestic market, for the purpose of achieving parity with international markets during fiscal 
year 2017, all of which occurred during the last quarter of 2017. 

Given this transition process to international prices and also that export duties on external prices were not extended in January 2017, 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. 

In addition, 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, 2017, the aggregate value of financial assets at fair value through profit or loss amounts to 31,987. 

The following table shows the effect that a 10% variation in the prices of investments in financial instruments would have on the

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. 

•

Liquidity Risk 

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, 2017 
the availability of liquidity reached 44,454, considering cash of 9,672, other liquid financial assets of 19,066 and available credit lines 
with banks of 15,716. 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 and in April 2016.

(1) 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 52% of the outstanding loans as of 
December 31, 2017 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 

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.

4. FINANCIAL RISK MANAGEMENT (Cont.) 

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. 

The provisions for doubtful accounts are measured by the following criteria: 

•

•

The aging of the receivable; 

The analysis of the customer’s capacity to return the credit granted, also taking into consideration special situations such as 
the existence of a voluntary reorganization petition, bankruptcy and arrears, and guarantees, among others. 

The maximum exposure to credit risk of the Groups of December 31, 2017 based on the type of its financial instruments and without 
excluding the amounts covered by guarantees and other arrangements mentioned below is set forth below: 

Cash and cash equivalents
Other financial assets

Maximum
exposure as of
December 31, 2017
28,738
63,911

Considering the maximum exposure to the risk of the Other financial assets based on the concentration variable of the counterparties, 
credit with the National Government and direct agencies accounts for approximately 31% (14,911), while the Group’s remaining 
debtors are diversified. 

Following is the breakdown of the financial assets past due as of December 31, 2017.

At such date, the provision for doubtful trade receivables amounted to 1,323 and the provisions for other doubtful receivables amounted 
to 292. 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 service 
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 10,789, 9,300 and 6,277 as of December 31, 2017, 
2016 and 2015, respectively. 

During the fiscal years ended December 31, 2017, 2016, and 2015, the Group executed guarantees received for an amount of 2, 1 and 2, 
respectively.

5. 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 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 

On March 15, 2016, the Gas and Power Executive Vice-presidency was created, and during the current fiscal year, the complete 
scope of management of this new business unit was determined. 

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 and Escobar, by hiring two regasification vessels, (iii) the natural gas distribution, and 
(iv) the generation of conventional and renewable electricity. 

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 since 2017, the Stimulus Plan for Surplus Natural Gas Injection, 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) oil refining and petrochemical production, (ii) commercialization of 
refined and petrochemical products obtained from such processes, (iii) logistics related to the transportation of 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 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. 

As required by IFRS 8, comparative information has been given retroactive effect by the creation of the new segment.

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 US 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 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.

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.

AS OF DECEMBER 31, 2017, 2016 AND 2015

6. FINANCIAL INSTRUMENTS BY CATEGORY (Cont.) 

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 estimating 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 Chief Financial 
Officer (“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 tables below show the Group’s financial assets measured at fair value as of December 31, 2017, 2016 and 2015 and their allocation 
to their fair value levels.

(1) As of December 31, 2017, it has been classified as Current. As of December 31, 2016, 7,737 have been classified as Noncurrent 

and 7,495 has been classified as Current. 

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, 2017, 2016 and 2015, 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 Negotiable Obligations and interest rates offered to 
the Group (Level 3) for the other financial loans remaining, amounted to 200,264, 157,133 and 106,336 as of December 31, 2017, 2016 
and 2015, 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.

On May 13, 2016, the companies Y-GEN I and Y-GEN II were created, for the purpose of submitting a bid to the tender No. 21/2016 
launched by the MINEM, for the new generation of energy and thermal power, which, if awarded, they would enter into with Compañía 
Administradora del Mercado Mayorista Eléctrico S.A. (“CAMMESA”) a contract of sale of offered energy for a term of between 5 and 
10 years, as offered, and with a price denominated in U.S. dollars. The created companies submitted their bids for the construction of 
new thermal power plants in Loma Campana (Añelo, Province of Neuquén) and in Central El Bracho (Province of Tucumán), which 
were finally awarded. 

In both companies, 66.67% of the shareholding is owned by the subsidiary YPF EE and the remaining 33.33% is owned by Guayama 
PR Holdings of the General Electric Group. 

The Group has followed the guidelines set forth in IFRS 10 “Consolidated financial statements” and has concluded that it exercises joint 
control over Y-GEN I and Y-GEN II. As a result, it has applied IFRS 11 “Joint Arrangements” which defines these companies as joint 
ventures, and has measured them in accordance with the equity method in accordance with IAS 28 “Investments in associates and joint 
ventures”. Some of the main assumptions under evaluation were as follows: (i) Contractually, both shareholders exercise joint control 

over each of the companies, so any decisions on their relevant activities are taken jointly, requiring their unanimous vote to do so and 
there is no power of one party (shareholder) over the other in relation to the investment, regardless of the different percentages of 
ownership thereof; (ii) there is no power as defined in IFRS 10 of one party to the detriment of another, either in relation to the voting 
rights in the nomination of directors or even personnel (whether key or not), in the management of the entity to benefit itself or to 
unilaterally modify the variable return on investment, or ultimately to unilaterally address any of the decisions associated with the 
relevant activities. In addition, see Note 3.

YPF SOCIEDAD ANONIMA
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2017, 2016 AND 2015

14. PROVISIONS (Cont.) 

The Group is party 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, among other factors, new information develops and results of the presented evidence are obtained. 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 clean up 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 litigation and contingencies 

As of December 31, 2017, 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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2017, 2016 AND 2015

14. PROVISIONS (Cont.) 

Resolution No. 1410/2010 of the ENARGAS also approved the procedure 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 
(Procedimiento para Solicitudes, Confirmaciones y Control de 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. 

Costs from contractual penalties arising from the failure to deliver natural gas until December 31, 2017, have been provisioned to the 
extent that such costs are probable and can be reasonably estimated.

AES Uruguaiana Empreendimentos 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 “deliver or pay” penalties mentioned 
above, all of which totaled approximately US$ 1,052 million.

AS OF DECEMBER 31, 2017, 2016 AND 2015

14. PROVISIONS (Cont.) 

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. 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 May 24, 2013, YPF was notified of the partial award decreed by a majority in the ICC Arbitration “YPF vs. AESU and TGM” 
whereby YPF was deemed responsible for the termination in 2009 of natural gas export and transportation contracts signed with AESU 
and TGM. Such award only decided on the responsibility of the parties, leaving the determination of the damages that could exist 
subject to the subsequent proceedings before the same Tribunal. Moreover, the Tribunal rejected the admissibility of “deliver or pay” 
claims asserted by SULGAS and AESU for the years 2007 and 2008 for a value of US$ 28 million and for the year 2006 for US$ 
2.4 million. On May 31, 2013, YPF filed with the Arbitration Tribunal a writ of nullity, in addition to making several presentations in 
order to safeguard its rights, which was rejected by such court. Against the rejection of the writ of nullity, on August 5, 2013 YPF filed 
an appeal with the Argentinian Ordinary Court (finally heard by the Federal Contentious Administrative Tribunal). Despite the 
foregoing, the Arbitration Tribunal continued as scheduled. 

On December 27, 2013, the Federal Contentious Administrative Tribunal hearing Administrative Litigation matters was moved to grant 
the reconsideration motion from denial on appeal, then sustaining the appeal for procedural violations and declaring that the grant 
thereof will have stay effects in connection with the arbitration process. 

Despite the foregoing, 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. 

On October 7, 2014, the Federal Court of Appeals hearing Administrative Litigation matters, besides having jurisdiction in the 
application of the writ of nullity, ordered the suspension of the court calendar related to the second stage of its arbitration process until a 
final court decision was rendered on the writ of nullity filed by YPF against the arbitral award on adjudication of liability. On 
October 8, 2014, the Arbitration Tribunal was served with notice of the decision rendered by the said Federal Court of Appeals and on 
October 31, 2014, the Arbitration Tribunal determined to suspend the arbitration process. In spite of the foregoing, on April 24, 2015, 
the Arbitration Tribunal resumed the proceedings and invited the parties to consult with each other regarding the continuation of the 
arbitration and to provide joint or individual report on next steps. On December 23, 2015, the Federal Contentious Administrative 
Tribunal granted the nullity request and vacated the partial arbitral award. On the same date, YPF notified the Arbitration Tribunal of 
the decision and requested the termination of the arbitration proceeding. On February 3, 2016, TGM filed an extraordinary appeal 
against the Federal Contentious Administrative Tribunal ruling to the National Supreme Court of Justice (“CSJN”). On February 2, 
2016, AESU and SULGAS filed a nullity request against the Federal Contentious Administrative Tribunal ruling, and on February 23, 
2016, the Tribunal rejected the request in limine. AESU and SULGAS filed a motion before the CSJN contesting this rejection, which 
was communicated to YPF on March 31, 2016. On the same date, the Court of Appeals rejected the motion to appeal before the CSJN 
filed by TGM on February 2, 2016.

14. PROVISIONS (Cont.) 

On April 26, 2016, Division IV of the Court denied the motion filed by AESU and SULGAS (which was communicated to YPF on 
March 31, 2016) and passed a new resolution declaring the nullity and ineffectiveness of all proceedings filed by the parties until then 
and by the Arbitration Tribunal regarding the second stage of the arbitration, on the basis that they lacked legal grounds. In turn, the 
resolution reiterates the legal order arising from Section 34, subsection 5, paragraph b, of the Argentine Civil and Commercial Code of 
Procedures (“CPCCN”), advising the Arbitration Tribunal that it may not issue any resolution regarding the second stage of the 
arbitration, including a final award of damages, and also advising AESU, SULGAS and TGM that any of their respective acts to that 
end or any act of the Arbitration Tribunal that might involve them, in violation of the above referred judgment, will be evaluated by the 
court in the exercise of its powers granted by the CPCCN as process manager (pursuant to section 45 and related sections). In addition, 
this Division was ordered to notify the Arbitration Tribunal and the International Arbitration Secretary’s Office for the ICC, advising 
them that the Arbitration Tribunal is not in a position to issue an award in accordance with applicable law. 

This resolution was communicated by YPF to the Arbitration Tribunal, the parties and the ICC. On the same date but following this 
notification, YPF was given notice of the arbitration damages award issued by a majority of the Arbitration Tribunal, whereby the 
Company was ordered to pay damages of US$185 million to AESU for the early termination of the gas export contract in 2009 and on 
account of the DOP penalty, and of US$ 319 million to TGM on account of the amount of its principal invoices, irrevocable 
contributions and damages for the early termination of the transportation contract. 

On May 2, 2016, YPF filed a writ of nullity with the ICC and the Arbitration Tribunal contesting the arbitration award. On the same 
date, it also filed a writ of nullity and, in the event the writ of nullity were not accepted, a complaint, before Division IV of the Federal 
Contentious Administrative Tribunal. 

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.) 

On March 12, 2010, YPF was notified of a complaint filed by TGN demanding compliance with the contract and payment of unpaid 
invoices from February 20, 2007 until December 15, 2010 for a total of US$ 64 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. 

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. As of the date of issuance of these consolidated financial statements, TGN’s claim is still pending. 

Taking into account the information available to date, the estimated time remaining until the completion of the process and the results of 
additional evidence presented in the continuation of the litigation, YPF has provisioned its best estimate with respect to the value of 
these claims.

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. 

YPF has provisioned its best estimate with respect to the claim mentioned above.

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. 

The Company has provisioned its best estimate for the aforementioned claim. 

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. 

The estimate of the claims for damages discussed above and the cost of the remediation actions, if required, are recorded in those 
situations where the loss is probable and can be reasonably estimated. 

•

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. 

Considering the information available as of the date hereof, the estimated time remaining until the completion of the litigation 
proceedings and the results of additional evidence presented in the litigation proceedings, the Company has provisioned its best estimate 
with respect to the value of the claims. 

•

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 provisioned 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.

15. INCOME TAX (Cont.) 

For fiscal year ended December 31, 2017, the Group estimated a tax loss carryforward of 8,776. 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, 2017 it is probable that the Group will realize all of the deferred income tax assets. 

As of December 31, 2017, Group’s tax loss carryforwards at the expected recovery rate were as follows:

• As of December 31, 2016, the Group did not record 1,138, corresponding to tax loss carry forwards from subsidiaries, 1,090 of 

which matured from 2017 onwards and 48 of which had indeterminate maturity. 

• As of December 31, 2015, the Group did not record 4,373, 2,041 of which corresponded to non-recoverable taxable temporary 

differences and 2,332 of which corresponded to tax loss carry forwards from subsidiaries. 

As of December 31, 2017, 2016, and 2015, the Group has classified as deferred tax assets for 588, 564, and 954, respectively, and as 
deferred tax liability 37,645, 42,465, and 44,812, respectively, all of which arise from the net deferred tax balances of each of the

As of December 31, 2017, 2016, and 2015, the causes that generate allocations to other comprehensive income, did not create

24. 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. 

The assets and liabilities as of December 31, 2017, 2016 and 2015, and expenses for the three fiscal years ended on December 31, 2017, 
2016 and 2015 of the JO and other agreements are as follows:

25. SHAREHOLDERS’ EQUITY 

The Company’s subscribed capital as of December 31, 2017, is 3,924 and 9 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 Argentine pesos 10 and 1 vote per 
share. These shares are fully subscribed, paid-in and authorized for stock exchange listing. 

As of December 31 2017, 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, 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. 

On April 28, 2017, the General and Extraordinary General Shareholders’ Meeting was held, which approved the financial statements of 
YPF for the fiscal year ended December 31, 2016 and, in addition, adopted the following resolution in relation to the distribution of 
profits: a) fully release the special reserve for initial adjustment due to the implementation of the IFRS in accordance with the 
provisions set forth in article 10 Chapter III Title IV of the CNV Regulations (TO 2013), the reserve for future dividends, the reserve 
for the purchase of own shares and the reserve for investments; b) fully absorb the accumulated losses in Unretained Results up to 
28,231 against the amounts corresponding to the released reserves for up to such amount; and c) the remainder of the released reserves 
to be allocated as follows: (i)the sum of 100 to a reserve fund for the purchase of own shares, for the purpose of granting the Board of 
Directors the possibility of acquiring its own shares at the time they deem appropriate, and to fulfill, during the execution of the plans, 
the commitments made and to be made by them in the future; and (ii) the sum of 716 to create a reserve fund for investments, 
authorizing the Board of Directors to determine the time of payment within a term that may not exceed the closing date of the fiscal 
year ended December 31, 2017. 

On June 8, 2017, the Board of Directors of the Company resolved the payment of a dividend of 1.82 per share for the sum of 716, 
which was overruled by the resolution of the Board of Directors adopted at the meeting held on July 9, 2017. Subsequently, on 
December 14, 2017, the Board of Directors of the Company decided to pay the aforementioned dividend, which was made available to 
the shareholders on December 27, 2017.

27. DECONSOLIDATION OF 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 various standards regulating 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 of the United States Bankruptcy Code (the “Bankruptcy Code”), actions to collect a 
monetary claim for such liabilities against the Debtors were generally 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 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 
Disclosure Statement. The Plan was structured around the 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. 

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 a.4.i) of this note).

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 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 (“Pospetition DIP Facility”) 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. The liquidating trust stated to the 
Bankruptcy Court that it intends to file claims in 2018. 

Considering the preceding events, and that the originally submitted agreements have not been approved by the Judge, the Management 
of the Company, in consultation with its legal advisors, has re-evaluated the amounts accounted for, based on the existing uncertainties. 

27.a.3) 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.4) determined that Maxus, TS and other related companies submit a reorganization petition under the Bankruptcy 
Law mentioned above. 

27.a.4) 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 Note 27.b). 

27.a.4.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.

27. DECONSOLIDATION OF MAXUS ENTITIES (Cont.) 

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 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”). 

Under the 2007 AOC, the lower 17 miles of the Passaic River, from the mouth at Newark Bay to Dundee Dam, should be 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 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. 

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 
(”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 (“2008 Removal Agreement”), 
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.4.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 the draft of the RI/FS in which offers potential remediation alternatives, (which 
comprises the lower 8 miles of the Passaic River). The EPA may or may not consider this report. 

27.a.4.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.5) 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 in December 2005, the DEP sued YPF, YPF Holdings, TS, Maxus and 
several companies, including Occidental (the “DEP Litigation”). The DEP sought remediation of natural resources damages and 
punitive damages and other matters. 

The defendants made responsive pleadings and filings. 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.

27. DECONSOLIDATION OF MAXUS ENTITIES (Cont.) 

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). 

The Special Master called for and held a settlement conference in November 2011 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). 

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 Moconi 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.

27. DECONSOLIDATION OF MAXUS ENTITIES (Cont.) 

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. 

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.

27. DECONSOLIDATION OF MAXUS ENTITIES (Cont.) 

(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. 

(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 tortious 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.

27. DECONSOLIDATION OF MAXUS ENTITIES (Cont.) 

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, and requiring 
that all pre-trial motions be filed with the Special Master by May 4, 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.

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 considers 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 Financial 
Accounting Standards Board, 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. 

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 has relevant effects on the rights that YPF Holdings has as a shareholder of 
these entities, because creditors generally replace 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, it should be noted that YPF Holdings retains its right to designate directors of the Debtors through 
Shareholders’ Meetings, unless the Bankruptcy Court orders otherwise. In addition, the bankruptcy cases also affect the responsibilities 
and functions of the board of directors and management of each of the respective Maxus Entities. Each of the Maxus Entities has 
become a “Debtor in Possession” and, in accordance with the Bankruptcy Code, remains in possession of its property and, subject to 
certain limitations, is authorized to carry out its normal operations, unless the Bankruptcy Court orders 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.

27. DECONSOLIDATION OF MAXUS ENTITIES (Cont.) 

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, the Group has recorded a gain of 1,528 in “Other net operating results”. 

As a result of the deconsolidation, the consolidated statements of financial position as of December 31, 2017 and 2016 are not 
comparable to the one issued as of December 31, 2015. As of December 31, 2015, the following asset and liability balances were

28.a) Contingent assets 

•

Cerro Divisadero 

On March 21, 2014 a fire incident damaged the facilities of Crude Oil Treatment Plant of Cerro Divisadero in Mendoza, belonging to 
the North Mendoza business, located 59 kilometers south from Malargüe city. In the mentioned facilities located in North Malargüe and 
South Malargüe, crude oil production was treated. Because of the incident, the facilities were almost completely unusable with the 
corresponding production loss. 

The pertinent insurers/reinsurers were notified of the event and after analyzing various technological options, in November 2015, all 
liquidated claims were settled for US$ 122.5 million, of which US$ 45.3 million corresponded to material damages and US$ 
77.2 million corresponded to loss of production, taking into account a US$ 60 million advance. 

In 2015, the Group recorded a gain of 1,165 in the consolidated statements of comprehensive income under “Other net operating 
results” and “Costs” in accordance with the nature of the claim (material damage and loss of production, respectively). 

In 2016, the Group received a second and final payment of US$ 62.5 million. 

•

La Plata Refinery 

On April 2, 2013, YPF’s facilities at the La Plata refinery were struck by unprecedented severe weather, which led to a fire that caused 
damage to the Coke A and Topping C units in the refinery. In operational terms, the incident temporarily affected the refinery’s ability 
to process crude oil, which left the entire complex out of service for several days. 

Based on the documentation provided to the liquidators appointed by the reinsurance companies, and following their analysis, the total 
indemnification amount as a result of the accident amounted to US$ 615 million, of which US$ 227 million corresponded to material 
damages and US$ 388 million corresponded to loss of profits. The indemnity period for loss of earnings because of the accident was 
extended to January 16, 2015. Payments were received gradually, US$ 300 million during the last quarter of 2013, US$ 130 million 
during the third quarter of 2014 and the remaining balance of US$ 185 million during the second quarter of 2015. 

In 2015, the Group recorded a gain of 523 in the consolidated statements of comprehensive income under “Revenues” and “Costs” in 
accordance with the nature of the claims. 

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. As of the date of issuance of 
these consolidated financial statements, the terms continue to be suspended as the plaintiff has not enforced the summons of the 
National Government;

(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 of which 
have been provisioned 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 shareholders, 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 seem to be mainly 
grounded on allegations that the expropriation breached contract obligations contained in the initial public offering and bylaws of YPF 
and seeks unspecified compensation. The Company 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. Currently, the matter is pending the 
resolution of the Court of Appeals. 

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. 

Currently, the proceedings are temporarily stayed, pending the decision of the Court of Appeals in the Petersen case. 

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.

Claims against natural gas producers 

On November 17, 2003, the CNDC requested explanations, within the framework of an official investigation pursuant to Article 29 of 
Law No. 25,156 of Antitrust Protection, from a group of almost thirty natural gas production companies, YPF among them, with respect 
to the following items: (i) the inclusion of clauses purportedly restraining trade in natural gas purchase/sale contracts; and 
(ii) observations on gas imports from Bolivia, in particular (a) old expired contract signed by YPF, when it was state-owned, and YPFB 
(the Bolivian state-owned oil company), under which YPF allegedly sold Bolivian gas in Argentina at prices below the purchase price; 
and (b) the unsuccessful attempts in 2001 by Duke and Distribuidora de Gas del Centro to import gas into Argentina from Bolivia. On 
January 12, 2004, YPF submitted explanations in accordance with article 29 of the Antitrust Law, contending that no antitrust violations 
had been committed and that there had been no price discrimination between natural gas sales in the Argentine market and the export 
market. On January 20, 2006, YPF received a notification of resolution dated December 2, 2005, whereby the Antitrust Board 
(i) rejected the “non bis in idem” petition filed by YPF, on the grounds that ENARGAS was not empowered to resolve the issue when 
ENARGAS Resolution No. 1,289 was enacted; and (ii) ordered that the opening of the proceedings be undertaken pursuant to the 
provisions of Section 30 of the Antitrust Law. On January 15, 2007, the Antitrust Board charged YPF and eight other producers with 
violations of the Antitrust Law. YPF has contested the complaint on the basis that no violation of the law took place and that the 
charges are barred by the applicable statute of limitations and has presented evidence in support of its position. On June 22, 2007, YPF 
presented to the Antitrust Board, without acknowledging any conduct in violation of the Antitrust Law, a commitment consistent with 
article 36 of the Antitrust Law, requiring to the Antitrust Board to approve the commitment, to suspend the investigation and to file the 
proceedings. On December 14, 2007, the Antitrust Board decided to transfer the motion to the Court of Appeals because of the appeal 
presented by YPF against the rejection of the application of the statute of limitations. The file was filed by the CNDC, without 
consequences for YPF.

Claims for fuel sale prices 

In addition, the Group was subject to other 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 abandoning wells 

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. 

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 exhaustion will inevitably occur. The Company has learned that similar 
disputes have been raised by the AFIP with other companies in the oil industry.

28. CONTINGENT ASSETS AND LIABILITIES (Cont.) 

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 3,997 considering principal and interest. 

On June 28, 2017, the Company was served with notice of an information request by AFIP through which it initiates a verification 
process regarding the deduction of the settlement costs corresponding to the fiscal periods 2011 to 2016 inclusive. 

On October 10, 2017, the Company was served with a notice sent by the AFIP, through which it reports an adjustment for the 2010 
fiscal period. On November 23, 2017, the corresponding discharge was filed. 

On October 13, 2017, the Company was notified of the closing of the inspection and the planned adjustment for the fiscal periods 2011 
to 2016 inclusive, which was rejected by means of a note submitted on October 23, 2017. 

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 its arguments defending the criteria adopted to be strong. 

•

Dispute over customs duties 

Between 2006 and 2009, the Customs General Administrations in Neuquén, Comodoro Rivadavia and Puerto Deseado informed the 
Company that certain summary proceedings had been brought against YPF based on alleged formal misstatements on future 
commitments of crude oil deliveries in the loading permits submitted before these agencies, 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. In addition, YPF has paid export duties on the market value of crude oil since its 
existence. 

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 the 
adverse judgment of the Tax Court in a timely fashion before the Court of Appeals, which has the power to grant staying effects on 
sanctions, which may only be requested under a final judgment, if applicable, and in the event the CSJN rules in favor of the Customs 
General Administration.

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 450 as of the date of this consolidated financial statements. 

Notwithstanding the progression of this process, 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.

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

On December 28, 2000, through Decree No. 1,252/2000, the Argentine Federal Executive Branch (the “Federal Executive”) extended

Agreements for the development of Loma La Lata Norte and Loma Campana areas 

On July 16, 2013, the Company and subsidiaries of Chevron Corporation (“Chevron”) subscribed a Project Investment Agreement (the 
“LC Agreement”) with the objective of the joint exploitation of unconventional hydrocarbons in the province of Neuquén. The LC 
Agreement contemplates an expenditure, subject to certain conditions, of US$ 1,240 million by Chevron for the first phase of work to

On December 10, 2013, the Company and some of its subsidiaries and subsidiaries of Chevron successfully completed the pending 
documents for the closing 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, 2017, 2016 and 2015. 

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 2017, 2016 and 2015, YPF and CHNC carried out transactions, among others, the purchases of gas and crude oil by 
YPF for 5,672, 5,912 and 3,556, 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, 2017, 2016 and 2015 amounts to 654, 544 and 553, 
respectively.

Agreements for the development of the Chihuído de la Sierra NegraSudeste– 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 closed with the perfection of the relevant assignments.

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

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. MAIN REGULATIONS AND OTHER (Cont.) 

30.d) Withholding rates of hydrocarbon exports 

Law No. 25,561 on Public Emergency and Exchange System Reform (“Public emergency law”), issued in January 2002, established 
duties for hydrocarbon exports for a five-year period. In January 2007, Law No. 26,217 extended this export withholding system for an 
additional five-year period and established specifically that this regime is also applicable to exports from the Province of Tierra del 
Fuego, which were previously exempt. In addition, Law No. 26,732 published in the Official Gazette in December 2011 extended for an 
additional 5 years the mentioned regime. On November 16, 2007, the Ministry of Economy and Production (“MEP”) published 
Resolution No. 394/2007, modifying the withholding regime on exports of crude oil and other refined products. 

In addition, Resolution No. 1/2013, published on January 3, 2013, and Resolution No. 803/2014, published on October 21, 2014, by the 
Ministry of Economy and Public Finance modified the reference and floor prices. Resolution No. 1,077/2014, dated December 29, 
2014, repealed Resolution No. 394/2007 and amended and established a new withholding system based on the International Price of 
crude oil (“IP”), calculated on the basis of the “Brent value” applicable to the export month minus eight dollars per barrel (US$ 
8.00/bbl). The new regime establishes a general nominal rate of 1% while IP is below US$ 71/bbl. Additionally, the resolution 
establishes an increasing variable rate for export of crude oil while IP is above US$ 71/bbl; therefore, the producer will collect a 
maximum value of about US$ 70 per exported barrel, depending on the quality of crude oil sold. Likewise, the resolution establishes a 
variable increasing withholding rates for exports of diesel, gasoline, lubricants and other petroleum derivatives when IP exceeds US$ 
71/bbl by using formulas allowing the producer to collect a portion of such higher price. 

Furthermore, in March 2008, Resolution No. 127/2008 of the MEP increased the natural gas export withholding rate to 100% of the 
highest price from any natural gas import contract. This resolution has also established a variable withholding system applicable to 
liquefied petroleum gas, similar to the one established by the Resolution No. 394/2007. In February 2015, Ministry of Economy and 
Public Finance Resolution No. 60/2015 modified the reference values of Resolution No. 127/2008 and reduced the export duty rate 
from 45% to 1% when IP was lower than the reference value. 

Notwithstanding the above, upon the expiration of the 5-year extension established by Law No. 26,732, which was in effect on 
January 7, 2017, the right to export hydrocarbons created by Article 6 of Law No. 25,561 was not extended. 

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.

30. MAIN REGULATIONS AND OTHER (Cont.) 

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.

Price agreement between crude oil producers and refiners 

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 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 oil prices, generally valid on a calendar-
month basis and linked to the Brent international benchmark, while maintaining limits on the exchange rate. 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.f) Programs for the production and refining of liquid hydrocarbons 

•

Refining and Petroleum Plus Programs 

Decree No. 2,014/2008 of the Department of Federal Planning, Public Investment and Services of November 25, 2008, created the 
“Refining Plus” and the “Petroleum Plus” programs to encourage (a) the production of diesel fuel and gasoline and (b) the production of 
crude oil and the increase of reserves through new investments in exploration and production. The programs entitle refining companies 
that undertake the construction of a new refinery or the expansion of their refining and/or conversion capacity and production 
companies that increase their production and reserves within the scope of the program to receive export duty credits to be applied to 
exports withholdings. In order to be eligible for the benefits of both programs, companies’ plans must be approved by the Argentine 
Secretariat of Energy.

30. MAIN REGULATIONS AND OTHER (Cont.) 

During February 2012, through Note No. 707/2012, supplemented by Note No. 800/2012, both issued by the Secretariat of Energy, YPF 
was notified that the benefits granted under the “Refining and Petroleum Plus” programs had been temporarily suspended. The effects 
of the suspension also apply to benefits accrued and not yet redeemed by YPF at the time of the issuance of the Notes. The reasons 
alleged for such suspension are that the programs had been created in a context where domestic prices were lower than prevailing prices 
and that the objectives of those programs had already been achieved. On March 16, 2012, YPF has challenged this temporary 
suspension. 

Pursuant to Decree No. 1,330/15 of July 6, 2015, the Government resolved to render ineffective the “Petroleum Plus” program, which 
had been created by Decree No. 2,014 of November 25, 2008.

Stimulus program for the production of crude oil 

On February 3, 2015, the Argentine Republic Official Gazette published the text of Resolution No. 14/2015 passed by the Commission 
for Planning and Coordination of the Strategy for the National Plan of Investment in Hydrocarbons that created the Crude Oil 
Production Promotion Program for 2015 under which beneficiary companies are awarded economic compensation, payable in pesos, for 
an amount equivalent to up to US$ 3.00/bbl for the total production of each beneficiary company, provided that its quarterly production 
of crude oil is higher or equal to the production taken as basis for such program. Basis production is defined as the total production of 
crude oil by beneficiary companies corresponding to the fourth quarter of 2014, expressed in barrels per day. The beneficiary 
companies that have met the demands of all refineries authorized to operate in the country and direct part of their production to the 
foreign market may receive an additional economic compensation of US$ 2.00 or US$ 3.00 for each barrel of exported crude oil, 
depending on the level of exported volume achieved. 

30.g) 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. 1,410/2010 that approved the procedure 
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 (Procedimiento para Solicitudes, Confirmaciones y Control de 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. 

MINEM Resolution No. 89/2016 - ENARGAS Resolution I - 3833 /16 – ENARGAS Resolution No. 4.502/17 

On June 1, 2016, the MINEM published Resolution No. 89 whereby: 

a)

ENARGAS was instructed to develop a procedure that modifies and supplements the one established in ENARGAS 
Resolutions No. 716/1998 and 1,410/2010 and establishes daily operation conditions of the Transportation and Distribution 
Systems.

30. MAIN REGULATIONS AND OTHER (Cont.) 

b)

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 1,410 / 2010 to the extent of the contracted volume. 

According to this Resolution, ENARGAS Resolution I/ 3,833 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. 

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 stated in the notice of call that given the expiration of the 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.

30. MAIN REGULATIONS AND OTHER (Cont.) 

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 US 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 being construed as an obligation. Additionally, the Terms and Conditions establish guidelines for early termination in the 
event of non-compliance by the parties.

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. 

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) 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 this case, it will be unnecessary 
to obtain the approval of each surplus export in the authorization, it will only be required to submit to the ENARGAS, for informative 
purposes only, the respective contract from which the interruptibility condition 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, provided for in Decree 
No. 893/2016.

Trust Fund to finance natural gas imports 

On November 27, 2008 through Executive Decree No. 2,067/08, 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. 1,982/11 that adjusted the tariff charges established by Executive Decree 
No. 2,067/08 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 2,067/2008 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 S.A. (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. 2,067/2008 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.

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”.

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 corporate producers which do not have a previous record of natural gas 
injection 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 will 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. 

These programs had a maximum duration of 5 years, and terminated on December 31, 2017, without having been renewed.

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. 

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.

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,

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)

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. 

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 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.

There have not been amendments to the definitions of included Non-Conventional Gas and Included Concessions, Price, or the Payment 
Conditions and Dates and Production Control, among other aspects initially included in the annex approved by Resolution 46-E/2017. 

On November 17, 2017, MINEM Resolution No. 447-E/2017 was published, which extends the application of the “Program to 
Encourage Investment in Development of Natural Gas Production from Unconventional Reservoirs” (applicable to the Neuquén Basin, 
created by MINEM Resolution No. 46-E/2017 and amended by MINEM Resolution No. 419-E/2017) to the production of natural gas 
from unconventional reservoirs located in the Austral Basin. 

30.i) 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. 

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.

30. MAIN REGULATIONS AND OTHER (Cont.) 

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 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, 2017 are described below: 

i.

2017 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 “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.

AS OF DECEMBER 31, 2017, 2016 AND 2015

30. MAIN REGULATIONS AND OTHER (Cont.) 

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. 

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 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 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 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.

30. MAIN REGULATIONS AND OTHER (Cont.) 

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. 

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 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. 

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. 

To date, the Memorandum of Agreement is subject to the controls established by the Emergency Law in order for the PEN to issue the 
ratification Decree. 

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. 

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.

30. MAIN REGULATIONS AND OTHER (Cont.) 

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 
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.

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, 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. As of the date of issuance of these consolidated financial statements, ENARGAS has not issued 
any decision regarding the appeal or the submitted tentative schedule. 

Such presentation does not imply withdrawal of the aforementioned appeal.

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. 

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 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. 

30.k) Regulatory framework for the electric energy industry 

Legal Framework 

Law No. 24,065, passed in 1992 and governed by Decree No. 1,398/92, has established the current basic regulatory framework for the 
electricity sector (the “Regulatory Framework”). This Regulatory Framework is supplemented by the regulations of the Secretariat of 
Energy (“SE”) for the generation and marketing of electric power, including the Resolution of the former Secretariat of Electric Energy 
No. 61/1992, “Procedures for the Scheduling of Operations, Load Dispatch and Price Calculation”, with its supplementary and 
amending regulations. 

The ENRE is the agency that regulates, oversees and controls the electric power industry and, in such capacity, it is responsible for the 
enforcement of Law No. 24,065. 

The technical dispatch, operation and economic organization of the Argentine Interconnection System (Sistema Argentino de 
Interconexion, or “SADI”) and the MEM is under the responsibility of CAMMESA. CAMMESA also acts as a collection agency for all 
MEM agents. 

It is possible to underscore the following main supplementary and amending resolutions of the sector, taking into consideration the 
power generation business of YPF EE: 

•

SE Resolution No. 146/2003: this resolution established the framework within which generators may request funding for 
major or extraordinary maintenance works with the goal of maintaining their units available. This funding may be repaid out 
of the future profits of the generation business, and it may be repaid in advance. Against this backdrop, YPF Energía 
Eléctrica, as the successor of the operations of the Power Plants of Tucumán and San Miguel de Tucumán, has requested 
funding for its plan for the maintenance and availability improvement of the plants in Tucumán, and has offered its Sale 
Settlements with No Expiration Date to Define (Liquidaciones de Venta sin Fecha de Vencimiento a Definir, or “LVFVD”) 
for the advanced repayment of the funded amounts.

SE Resolution No. 406/2003: this resolution established the mechanism to set collection priorities among various 
remunerative items of the power generation plants. This set priorities for the collection of items related to variable costs and 
the collection of the power made available to the system, and finally, of amounts related to generation margins for the sales 
made in the Spot market as per the curve of contracts with Large Users registered between May and August 2004. 

2008-2011 Generators Agreement: On November 25, 2010, the SE and the main electricity generator companies signed the 
“Agreement for the Management and Operation of Projects, Increase of Power Generation Availability and Adjustment of 
Remuneration for 2008-2011 Generation” (hereinafter, the “Generators Agreement”). This Generators Agreement was aimed 
at establishing the framework, conditions and undertakings that the parties should make to continue with the MEM 
adjustment process, to enable the entry of new generation to cover the increase in the demand for energy and power in such 
market, to determine a mechanism for the repayment of the consolidated debts of generators incurred between January 1, 
2008, and December 31, 2011, and the acknowledgment of global remuneration for MEM Generator Agents adhering to the 
Generators Agreement. YPF Energía Eléctrica, as a company continuing with the operation of the power plants of El Bracho 
Generation Complex, has debts with CAMMESA, arising from this agreement. 

SE Resolution No. 95/2013: this resolution establishes a new remuneration scheme based on the items described below and 
classified in terms of size and type of generation technology used. The defined remunerative items pertain to: a) 
remuneration for fixed costs; b) remuneration for variable costs other than fuel; c) direct additional remuneration; and d) 
indirect additional remuneration, which will be allocated to a trust for the development of electric power infrastructure 
works. It is necessary to accept the terms and conditions of the resolution to access such remunerations. YPF Energía 
Eléctrica has adhered to this system in August 9, 2013, backdated to February 1, 2013. Among other matters governed by 
this resolution, it should be noted that it established that until the SE decides otherwise, generators and large users will 
refrain from making new contracts and/or renewing existing contracts (except for contracts under the framework of SE 
Resolution No. 1,281/2006 “Energy Plus” and SE Resolution No. 220/2007, among others) as of the entry into force of the 
resolution. Furthermore, it establishes that as from the date of termination of existing contracts, large users will begin to 
make their power purchases through the agency in charge of dispatch (CAMMESA). Similarly, it establishes that fuel supply 
contracts will only be acknowledged as long as they are in force, and no new contracts may be made and existing contracts 
may not be renewed as from their termination dates. Similarly, it provides that fuel supply contracts will only be recognized 
while they are in force, and new ones may not be entered into or the current ones renewed as from their expiration date. 

SE Resolution No. 529/2014: this resolution replaces the remuneration scheme established by SE Resolution No. 95/2013, 
increasing the tariff schedule of the 4 remunerative concepts included by that resolution. In relation to the Fixed Costs, this 
resolution establishes an increase related to the availability of each Generator Agent and incorporates a new remuneration 
scheme of non-recurring maintenance, which aims to the funding of major maintenance subject to the approval of the SE. 
This resolution will be applicable to economic transactions from February 2014 for generators that had adhered to SE 
Resolution No. 95/2013. 

SE Resolution No. 482/2015: this resolution provides adjustments to the compensation scheme set forth in SE Resolution 
No. 529/2014, by increasing the tariff schedule of the five concepts provided for therein. In addition, it introduces a new 
specific contribution scheme known as “Resources for 2015-2018 FONINVEMEM Investments” to be allocated to 
generators participating in the investment projects approved or to be approved by the Secretariat of Energy, and a new 
incentive scheme for the Production of Energy and Operating Efficiency for the relevant generator agents therein included. 
The provisions of this resolution are retroactively applied to financial transactions made as of February 2015 for those 
generators who have adhered to SE Resolution No. 95/2013.

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.

exchanges or similar markets, when the stockbroker did not withhold the tax. 

•

Tax on Fuels 

The main modifications are the following: 

•

The tax modifies its name (formerly “Tax on Liquid Fuels and Natural Gas”, and now “Tax on liquid fuels”). 

• A new tax is introduced: Tax on carbon dioxide.

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. 

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. 

Other than as mentioned in Note 15 with respect to taxes on gains, the mentioned modifications do not have a significant effect on the 
financial statements of the Group.

34. SUBSEQUENT EVENTS 
•

On February 8, 2018, our subsidiary Metrogas entered into an unsecured loan with (i) Industrial and Commercial Bank of China 
Limited – Dubai Branch and (ii) Itaú Unibanco – New York Branch, in an amount of US$ 250 million for a term of 36 months. 
The loan is repayable in 9 quarterly installments as from the 12 months anniversary of the disbursement date. This loan will accrue 
interest (payable quarterly) at a rate of LIBOR plus an annual nominal margin of (a) 3.00% during the first 12 months, (b) 3.50% 
from month 13th to month 18th, (c) 3.75% from month19th to month 24th and (d) 4.00% from month 25th to the maturity date. 
Metrogas used the funds mainly to redeem, on February 27, 2018, all its NOs at a redemption price equal to 100% of the principal 
amount of the NOs to be redeemed, plus any accrued and unpaid interest thereon, and all the other amounts that were due and 
payable up to the redemption date.

Regarding the agreement for the capitalization of YPF EE mentioned in Note 3, 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.), 
subscribed YPF EE shares representing 24.99% of its capital stock, undertaking to such end to contribute US$ 275 million plus a 
contingent payment of up to US$ 35 million. Since then, GE EFS Power Investments and YPF jointly control YPF EE. 

On April 3, 2018, the MINEM published Resolution N° 97/2018 in the Official Gazette that approves the procedure for 
cancelation of the pending compensations under the “Natural Gas Additional Injection Stimulus Program”, the “Natural Gas 
Injection Stimulus Program for Companies with Reduced Injection” and the “Natural Gas New Projects Program” corresponding 
to 2017 natural gas injections (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. 

In order to determine the amount of the compensation, the Secretariat of Hydrocarbon Resources shall issue a “Resolution of 
Compensation”, calculated as follows: 

1.

2.

85%: the amount in USD calculated using the exchange rate at the time of injection of the natural gas. 

15%: the amounts in USD calculated using the exchange rate between the time of injection and the time of payment 
due or the exchange rate as of the date of the Resolution, as per corresponds. 

The compensation shall be monthly paid in 30 equal and consecutive payments as from January 2019 using the exchange rate 
“Comunicacion A 3500 Mayorista” corresponding to each payment of each month. 

Gas producing companies joining the Procedure shall waive all claims, legal actions and measures as well as accept the terms and 
conditions of payment compensations under the Procedure during the maximun period of 20 working days since the publication of 
the Resolution in the Official Gazette of the Republic of Argentina. As of the date of this annual report we are analyzing the 
necessary steps to comply with said Resolution. 

On March 28, 2018 Decree No. 252/2018 was published in the Official Gazette by which the PEN ratified the Memorandum of 
Agreement, mentioned in Note 30.i). Also, Resolution ENARGAS No. 300/2018 was published on that day, with the new tariffs 
scheme applicable as from April 1, 2018 

On April 5, 2018, the Company was notified that the ENARGAS rejected the motion for reconsideration submitted by YPF on 
March 30, 2017, mentioned in Note 30.i). As of the date of this annual report, we are discussing the following legal steps as a 
result of the previously mentioned rejection. 

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, 2017, which were not already considered in such 
consolidated financial statements according to IFRS. 

The consolidated financial statements as of December 31, 2017, presented for regulatory purposes before the CNV, have been approved 
by the Board of Director’s meeting and authorized to be issued on March 2, 2018, and will be considered in the shareholders’ meeting. 
These consolidated financial statements, which comprise those presented before the CNV on March 2, 2018, 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 23, 2018.

35. SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED) 

The following information is presented in accordance with Accounting Standards Codification (“ASC”) No. 932 “Extractive Activities 
– Oil and Gas”, as amended by Accounting Standards Update (“ASU”) No. 2010 – 03 “Oil and Gas Reserves. Estimation and 
Disclosures”, issued by Financial Accounting Standards Board (“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, 2017, 2016 and 2015 was calculated in accordance with the SEC rules and ASC 
932, as amended. Accordingly, crude oil prices used to determine reserves were calculated at the beginning of each month, for crude 
oils of different quality produced by the Group. Consequently, for calculation of our net proved reserves as of December 31, 2017, the 
Group considered the realized prices for crude oil in the domestic market (which are higher than those that had prevailed in the 
international market), taking into account the unweighted average price for each month within the twelve-month period ended 
December 31, 2017. Additionally, since there are no benchmark market natural gas prices available in Argentina, the Group used 
average realized gas prices during the year to determine its gas reserves. 

Notwithstanding the foregoing, commodity prices have declined significantly since 2014. 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 2017 

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. 

Changes in YPF’s Estimated Net Proved Reserves 

The table below sets forth information regarding changes in YPF’s net proved reserves during 2017, 2016 and 2015, by hydrocarbon 
product.

(1) Volumes of natural gas have been converted to barrels of oil equivalent at 5,615 cubic feet per barrel. 
(2) Revisions in estimates of reserves are performed at least once a year. Revision of crude oil, natural gas liquids and natural gas 

reserves are considered prospectively in the calculation of depreciation. 

(3) Barrel of oil equivalent production of consolidated entities for the years 2017, 2016 and 2015 includes an estimated approximately 
25, 27 and 26 mmboe, respectively, in respect of royalty payments which, as described above, are a financial obligation, or are 
substantially equivalent to a production or similar tax. Barrel of oil equivalent production of equity-accounted entities in respect of 
royalty payments which are a financial obligation, or are substantially equivalent to a production or similar tax, are not material. 

(4) Proved oil equivalent reserves of consolidated entities as of December 31, 2017, 2016 and 2015 include an estimated 

approximately 119, 144 and 176 mmboe, respectively, in respect of royalty payments which, as described above, are a financial 
obligation, or are substantially equivalent to a production or similar tax. Proved oil equivalent reserves of equity-accounted entities 
in respect of royalty payments which are a financial obligation, or are substantially equivalent to a production or similar tax, are 
not material. 

The paragraphs below explain in further detail the most significant changes in our proved reserves during 2017, 2016 and 2015. 

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 occurred mainly in fields of Neuquina 
basin (-60 mmboe), Golfo San Jorge Basin (-25 mmboe) and Cuyana Basin (-14 mmboe).

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2017, 2016 AND 2015

35. SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED) (Cont.) 

• 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 reserved 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. 

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.

YPF SOCIEDAD ANONIMA
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2017, 2016 AND 2015

35. SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED) (Cont.) 

• 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. 

Changes in our estimated proved reserves during 2015 

•

Extensions and Discoveries 

Wells drilled in unproved reserves and resource areas added approximately 54 mmboe of proved developed reserves (20 mmbbl of 
crude oil, 2 mmbbl of NGL and 178 bcf of natural gas), and 93 mmboe of proved undeveloped reserves (24 mmbbl of crude oil, 8 
mmbbl of NGL and 342 bcf of natural gas). 

The 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 

Approximately 23 mmboe of proved reserves were added mainly due to new projects and positive production response. The main 
contributions came from the Golfo San Jorge basin (8 mmboe proved developed reserves and 5 mmboe proved undeveloped reserves) 
and the Neuquina basin (5 mmboe proved developed reserves and 3 mmboe proved undeveloped reserves). Minor additions came from 
the Cuyana and Austral basins. 

•

Sales and Acquisitions 

As a result of sales and acquisitions, proved reserves declined by 16.3 mmboe (-8.2 mmboe proved developed reserves and -8.1 mmboe 
proved undeveloped reserves). This reduction in reserves was mainly related to a modification in the joint venture agreement in the 
Rincón del Mangrullo field. Additionally, in the El Orejano field, a new joint venture resulted in a reduction of proved developed 
reserves. 

•

Revisions of Previous Estimates 

During 2015, the Company’s proved reserves were revised upwards by 71 mmboe (31 mmbbl of crude oil, 9 mmbbl of NGL and 175 
bcf of natural gas). 

The main revisions to proved reserves were due to the following: 

•

•

Total liquids and gas production performance was better than expected, resulting in a 56 mmboe (29.3 mmbbl of crude oil, 
5.7 mmbbl of NGL and 117 bcf of natural gas) addition to proved developed reserves. The most significant additions came 
from the Neuquina and Golfo San Jorge basins. The main fields which performed below expectations were in the Austral 
basin, resulting in these cases in a reduction of proved reserves. 

Scheduled compression projects and corresponding production forecasts were reviewed according to the reservoir’s current 
performance and the available compression technology. This revision resulted in a 21 mmboe addition to proved reserves in 
the Neuquina basin. 

• Approximately 17 mmboe (8.8 mmbbl of crude oil and 47.4 bcf of natural gas) of proved reserves were added as a result of 
feasibility studies performed to include new projects pursuant to field development plans, mainly in the Golfo San Jorge 
basin. Proved reserves were also added in the Austral and Neuquina basins. 

This was partially offset by: 

• Mainly as a result of the impact of lower average oil prices in 2015 on economics, 21 mmboe (9.4 mmbbl of crude oil and 

64.6 bcf of natural gas) of proved reserves were removed. This price reduction primarily affected reserves in the Austral, 
Golfo San Jorge and Neuquina basins. 

• 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 and Golfo San Jorge basins.

Introduction 

YPF S.A. is a company widely recognized for its high quality standards relative to the values and principles it promotes. Ethics is 
embedded in all its activities, focusing not only on the results but also on how they are achieved. YPF S.A. expects integrity across the 
Organization and shall not tolerate the accomplishment of goals in violation of the laws or ethical principles. 

This Code of Ethics and Conduct demands the commitment of all those to whom it is addressed. 

1.

Considerations 

These Regulations as well as any amendments thereto and any compliance exemption require the approval of the Board of Directors of 
YPF S.A. Besides, the Board of Directors of YPF S.A. may decide to extend its scope of application to other individuals whenever 
required by regulations applicable to YPF S.A. 

The compliance of this Code of Ethics and Conduct (hereinafter the “Code of Ethics and Conduct” or the “Code”) shall be the sole and 
personal responsibility of each and every Subject Person (as defined below). Upon publication of the application of this Code, no 
infringement based on lack of awareness or obedience to a superior officer shall be admitted. 

All Subject Persons are expected to adopt a proactive attitude towards potential breaches, acting either on their own initiative or upon 
detection of incidents in breach of the Code of Ethics and Conduct. 

Non-compliance of this Code shall result in disciplinary actions proportional to the breach involved, which may even lead to the 
termination of the employment or contractual relationship, as appropriate, and give rise to the initiation of the relevant legal 
proceedings. 

This Code of Ethics and Conduct provides a wide guideline relative to the acceptable individual or corporate behavior. However, it 
cannot cover all potential situations. Consequently this Code does not relieve any of the Subject Persons from the responsibility or duty 
to exercise their sound judgment reflecting the values and principles outlined in this Code. 

These Regulations together with other internal documents and instruments support YPF S.A. commitment to good corporate 
governance, transparency and social responsibility. 

2.

and regulations governing the Company’s activity. 

Upon the publication of this Code, references to the specific rules and standards issued by the Company will be included in each case. 

5.

The “Ethics Line” is a system for reporting, among other things, situations and/or acts that might constitute an actual or potential breach 
of this Code. 

YPF shall encourage the use of this Line and ensure that the good faith reports informed through it shall not be subject to reprisals 
affecting the employment and/or contractual relationship and professional development of the reporting party. 

The “Ethics Line” shall be supervised by YPF’s Ethics Committee, which is in charge of implementing the Code of Ethics and Conduct 
of YPF, and assessing and establishing the actions required to address the reported situations. 

The Committee will be composed of five members, three of which shall serve as Internal Auditor, Legal Affairs Corporate Vice-
President and Human Resources Vice-President, while the other two will be appointed by the Chairman of the Board of Directors of 
YPF S.A. from among the employees discharging functions in operative or business areas. The presence of an absolute majority of its 
members shall be required at Committee meetings and decisions shall be adopted by a simple majority. Investigations shall be 
conducted by an Ethics and Compliance Officer reporting to the Legal Affairs Vice-Presidency. 

Any situation contrary to this Code informed by, or related to the behavior of the members of the Company’s Board of Directors shall 
be reported to the Audit Committee. The following situations shall also be reported forthwith to the Audit Committee: i) any situation 
that might have an impact on the supervision of the financial information or material events submitted to the National Securities 
Commission (Comisión Nacional de Valores) and the markets; and ii) any report related to the operation of YPF’s internal control, 
administrative-accounting and audit systems.

• Not to use confidential information for fraudulent purposes. The restriction on use and non-disclosing duty shall survive the 

termination of the employment, business or any other type of relationship with YPF.

lead to legal actions. 

The Subject Persons under this Code shall take the strictest care to protect the confidentiality of, and may not disclose, directly or 
indirectly, any relevant non-public information, including highly sensitive information that could affect the price of YPF securities or 
their trading process in the markets. Any breach of the existing policy for the management of this type of information may derive in

periods that might be applicable to the circumstances being faced by YPF. 

6.2.8. Prohibited periods for trading YPF securities

exclusively and fully owned by YPF. Reports, proposals, studies, programs and any other product resulting from the professional 
activity discharged at YPF shall remain in the possession of YPF. Moreover the Subject Person no longer serving the Company shall 
not copy, reproduce or disclose the same without the written approval from YPF. 

Subject Persons further undertake to return all materials owned by YPF which are in their possession upon the termination of their 
activity at YPF. 

6.2.11.Anti-bribery and anti-corruption measures 

Subject Persons shall not directly or indirectly make or offer any payment in cash, in kind or any other benefit to any person at the 
service of a public or private entity, political party or candidates to public offices with the intention of unlawfully procuring, gaining or 
maintaining a given business or any other advantage. 

Furthermore, Subject Persons shall not directly or indirectly make or offer any payment in cash, in kind or any other benefit to any 
person with the intention of causing the latter to abuse its actual of presumed influence to conclude a deal or derive another advantage 
from a public or private entity.

Subject Persons shall not make any payments in cash or deliver any items of value, regardless of their amount, to facilitate or speed up 
processes or to ensure the course of a procedure or action before any judicial authority, public administration or official body in which 
YPF is involved for the benefit or in the interest of YPF. 

In addition to the consequences of violating these Regulations provided in the specific paragraph hereof, and other consequences not 
related to employment/contractual issues, Subject Persons acknowledge that the breach of the provisions of this paragraph may cause a 
considerable damage to the reputation and good name of YPF. 

In order to prevent and avoid the laundering of money from criminal or illegal activities, the Directors and Employees shall devote 
special attention to cases where there are signs of lack of integrity of the individuals or entities with whom business is carried out, as 
well as observing their duty to comply with the applicable legal provisions.

5.1. Relevant Information: Concept

The term “Relevant Information” refers to every fact or situation that, in view of its significance, might materially affect the 
placement of securities, their trading or the conduct of the Subject Person’s business. The concept of Relevant Information equally 
includes any information whose knowledge might reasonably influence an investor to acquire or transfer securities or other 
financial instruments, with the consequent material effect on their trading on a secondary market. 

5.2. Duty to report Relevant Information 

YPF hereby undertakes to immediately inform the market through a notice addressed to the National Securities Commission 
(Comisión Nacional de Valores – CNV) as well as to any pertinent entities according to the markets where YPF’s securities are 
traded, of any Relevant Information concerning the Company, in compliance with applicable regulations. Where appropriate, 
YPF’s Internal Transparency Committee —created by the Board of Directors and composed by the Company’s senior 
executives— shall take cognizance of this situation and proceed accordingly.

Subject Persons shall refrain from preparing or conducting practices that falsify free pricing, and from those stipulated in 
Section 117, subsection b) of Law 26,831 and Section 2, Chapter III, Title XII (Listing Transparency) of CNV’s Rules (as 
amended in 2013), and any regulatory or superseding provisions thereof. 

7.2. Prohibited practices 

This term encompasses practices and behaviors aimed at or allowing for the manipulation of prices or trading volume of securities, 
thereby altering the normal development of the supply and demand, and any other practices capable of misleading market 
participants, in respect of the purchase or sale of any listed securities, whether by means of artifices, false or inaccurate statements 
omitting basic facts or any act, practice or course of action with deceptive and detrimental effects on any person operating in the 
market. 

8. CONFLICTS OF INTEREST 

8.1. Prior communication 

In order to control any potential conflicts of interest, all Subject Persons shall inform the Ethics Committee and/or the Audit 
Committee (in the case of Board members), before conducting any transaction or concluding any business, with sufficient time in 
advance to enable the timely implementation of adequate measures, regarding situations that might potentially, and in each 
specific circumstance, give rise to a conflict of interest with YPF or any subsidiary and/or affiliate, by virtue of said Subject 
Persons’ activities outside YPF, or those of their relatives or acquaintances, their assets, or for any other reason, and that might 
compromise their impartial performance. 

8.2. Duty of abstention 

The Subject Persons shall refrain from participating in situations that might give rise to a conflict between their personal interests 
—and/or the interest of Related Persons— and YPF’s interests. The Subject Persons shall also abstain from participating in or 
exerting influence over decisions regarding situations where a personal interest is at stake, whether directly or indirectly; in all

Dear Mr. Carlos Colo, 

Proved Hydrocarbon Reserves Statement 
for YPF S.A. for Certain Argentine Properties 
as of December 31, 2017 

This Proved reserves statement has been prepared by Gaffney, Cline & Associates (GCA) and issued on February 21, 2018 at the 
request of YPF S.A. (YPF or “the Client”), in respect of certain assets in Argentina where YPF has a participating interest. YPF’s 
participating 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, 2017, of the hydrocarbon liquid and natural gas proved 
reserves of 50 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 Field (100%) 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 21.4 Bm3 includes 1.6 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 Field (100%) and YPF Net Reserves for each basin. 

YPF has advised GCA that the YPF reserves estimated in this report constitute approximately 28.2% percent of YPF’s Proved reserves 
and that the Proved Undeveloped Reserves estimated in this report constitute approximately 34.1% percent of all of YPF’s Proved 
Undeveloped Reserves as of December 31, 2017. 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 6, 2018. 

2 

Reserves Assessment 

GCA’s audit of the YPF reserves estimates was based on decline curve analysis to extrapolate the production of existing wells or 
elaborate 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/categorization of the 
proposed development plan. 

This audit examination was based on reserves estimates and other information provided by YPF to GCA from September 2017 to 
February 2018 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, 2017 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, 2017 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, 2017 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, 2017. There 
were no published benchmark crude oil prices during 2017 in Argentina that relate to YPF’s oil production from which 
first-day-of-month prices could be obtained. Additionally, since there are no benchmark market natural gas prices available in 
Argentina, YPF used average realized gas prices during the year to determine its reserves. 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, 2017, 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 is 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.

Reserves are further categorized in accordance with the level of certainty associated with the estimates and may be sub-classified based

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. 

1

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]. 

19 

(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. 

20 

(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; 

21 

(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. 

22 

(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. 

23 

(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. 

24 

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.
