Forward-Looking Statements  

This annual report, including any documents incorporated by reference, contains statements that we believe constitute forward-

trends affecting our financial condition, financial ratios, results of operations, business, strategy, geographic concentration, reserves,

available to the company, dates or periods in which production is scheduled or expected to come onstream, 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, 
investments and dividend policies could differ materially from those expressed or implied in any such forward-looking statements. 
Such factors include, but are not limited to, currency fluctuations, the price of petroleum products, the ability to realize cost reductions 
and operating efficiencies without unduly disrupting business operations, replacement of hydrocarbon reserves, environmental, 
regulatory and legal considerations and general economic and business conditions in Argentina, as well as those factors described in

ITEM  3.  Key Information  

Selected Financial Data  

The following tables present our selected financial and operating data. You should read this information in conjunction with our 
Audited Consolidated Financial Statements and related notes, and the information under “Item 5. Operating and Financial Review and 
Prospects” included elsewhere in this annual report.  

The financial data as of December 31, 2009, 2008 and 2007 and for the years then ended is derived from our Audited 
Consolidated Financial Statements, which are included in this annual report. The financial data as of and for the years ended 
December 31, 2006 and 2005 is derived from our audited financial statements, which are not included in this annual report. Our 
audited financial statements have been prepared in accordance with generally accepted accounting principles in Argentina, which we 
refer to as Argentine GAAP and which differ in certain significant respects from generally accepted accounting principles in the 
United States, which we refer to as U.S. GAAP. Notes 13, 14 and 15 to our Audited Consolidated Financial Statements provide a 
description of the significant differences between Argentine GAAP and U.S. GAAP, as they relate to us, and a reconciliation to U.S. 
GAAP of net income and shareholders’ equity as of December 31, 2009, 2008 and 2007 and for the years then ended.  

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

to “Ps.” and “pesos” are to Argentine pesos. Solely for the convenience of the reader, peso amounts as of and for the year ended 
December 31, 2009 have been translated into U.S. dollars at the exchange rate quoted by the Argentine Central Bank (Banco Central 
de la República Argentina or Central Bank) on December 31, 2009 of Ps.3.80 to U.S.$1.00, unless otherwise specified. The exchange 
rate quoted by Central Bank on June 23, 2010 was Ps.3.93 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.”

(1)  Consolidated income and balance sheet data for the year ended December 31, 2005 set forth above include the retroactive effect 

from the application of new accounting rules in Argentina effective since January 1, 2006.  

(2)  The financial statements reflect the effect of changes in the purchasing power of money by the application of the method for 

remeasurement in constant Argentine pesos set forth in Technical Resolution No. 6 of the Argentine Federation of Professional 
Councils in Economic Sciences (“F.A.C.P.C.E.”) and taking into consideration General Resolution No. 441 of the National 
Securities Commission (“CNV”), which established the discontinuation of the remeasurement of financial statements in constant 
Argentine pesos as from March 1, 2003. See Note 1 to the Audited Consolidated Financial Statements.  
Includes Ps.1,433 million for the year ended December 31, 2009, Ps.1,770 million for the year ended December 31, 2008, 
Ps.1,350 million for the year ended December 31, 2007, Ps.1,451 million for the year ended December 31, 2006, and Ps.1,216 
million for the year ended December 31, 2005 corresponding to the proportional consolidation of the net sales of investees in 
which we hold joint control with third parties. See Note 13(b) to the Audited Consolidated Financial Statements.  

(3) 

(4)  Net sales are net to us after payment of a fuel transfer tax, turnover tax and, from 2002, customs duties on hydrocarbon exports. 

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 in 
determining net sales. See “Item 4. Information on the Company—Exploration and Production—Oil and gas production, 
production prices and production costs” and Note 2 (f) to the Audited Consolidated Financial Statements.  
Information has been calculated based on outstanding capital stock of 393,312,793 shares. Each ADS represents one Class D 
share. There were no differences between basic and diluted earnings per share and ADS for any of the years disclosed.  

(5) 

(6)  Amounts expressed in U.S. dollars are based on the exchange rate as of the date of payment. For periods in which more than one 
dividend payment was made, the amounts expressed in U.S. dollars are based on exchange rates at the date of each payment.  
(7)  Total debt under Argentine GAAP includes nominal amounts of long-term debt of Ps.2,140 million as of December 31, 2009, 
Ps.1,260 million as of December 31, 2008, Ps.523 million as of December 31, 2007, Ps.510 million as of December 31, 2006, 
and Ps.1,107 million as of December 31, 2005.  

(8)  Our subscribed capital as of December 31, 2009 is represented by 393,312,793 shares of common stock and divided into four 

classes of shares, with a par value of Ps.10 and one vote per share. These shares are fully subscribed, paid-in and authorized for 
stock exchange listing.

Exchange Rates  

From April 1, 1991 until the end of 2001, the Convertibility Law (Law No. 23,928) established a fixed exchange rate under 
which the Central Bank was obligated to sell U.S. dollars at one peso per U.S. dollar. On January 6, 2002, the Argentine Congress 
enacted the Public Emergency Law (Law No. 25,561, the Public Emergency and Foreign Exchange System Reform Law), formally 
putting an end to the Convertibility Law regime and abandoning over 10 years of U.S. dollar-peso parity. The Public Emergency Law, 
which has been extended until December 31, 2011, grants the executive branch of the Argentine government the power to set the 
exchange rate between the peso and foreign currencies and to issue regulations related to the foreign exchange market. Following a 
brief period during which the Argentine government established a temporary dual exchange rate system pursuant to the Public 
Emergency Law, the peso has been allowed to float freely against other currencies since February 2002 although the government has 
the power to intervene by buying and selling foreign currency for its own account, a practice in which it engages on a regular basis.  

The 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 Controls  

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 currency 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. Since January 2003, the Central Bank has gradually eased these restrictions 
and expanded the list of transfers of funds abroad that do not require its prior authorization (including the transfer of funds to pay 
dividends). In June 2003, the Argentine government set restrictions on capital flows into Argentina, which mainly consisted of a 
prohibition against the transfer abroad of any funds until 180 days after their entry into the country. In June 2005, the government 
established further restrictions on capital flows into Argentina, including increasing the period that certain incoming funds must 
remain in Argentina to 365 calendar days and requiring that 30% of incoming funds be deposited with a bank in Argentina in a non-
assignable, non-interest-bearing account for 365 calendar days. Under the exchange regulations currently in force, restrictions exist in 
respect of the repatriation of funds or investments by non-Argentine residents. For instance, subject only to limited exceptions, the 
repatriation by non-Argentine residents of funds received as a result of the sale of the Class D shares in the secondary market is 
subject to a limit of U.S.$500,000 per person per calendar month. In order to repatriate such funds abroad, non-Argentine residents

also are required to demonstrate that the funds used to make the investment in the Class D shares were transferred to Argentina at least 
365 days before the proposed repatriation. The transfer abroad of dividend payments is currently authorized by applicable regulations 
to the extent that such dividend payments are made in connection with audited financial statements and are approved by a 
shareholders’ meeting.  

Risk Factors  

YPF’s operations and earnings are subject to risks as a result of changes in competitive, economic, political, legal, regulatory, 

social, industrial, business and financial conditions. Investors should carefully consider these risks.  

As a result of the recent global financial crisis and the continuing uncertain economic environment, certain risks may gain more 
prominence either individually or when taken together. Certain oil and gas prices and margins may be lower than in recent years due 
to reduced demand and certain other factors.  

Risks Relating to Argentina  

Our business is largely depend upon economic conditions in Argentina  

Substantially all 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 Argentine economy has experienced significant volatility in 
recent decades, including numerous periods of low or negative growth and high and variable levels of inflation and devaluation. Since 
the most recent crisis of 2001 and 2002, the Argentine economy has grown at a rapid pace during recent years, with real GDP 
increasing at an average cumulative rate of 8.5% between 2003 and 2008. As a result of the crisis in the global economy, Argentina’s 
GDP growth rate decelerated to approximately 1% in 2009, according to preliminary data. No assurances can be given that growth 
will resume at historical rates, or at all, in 2010 or subsequent years or that the economy will not contract. See “Item 5. Operating and 
Financial Review and Prospects—Factors Affecting Our Operations—Macroeconomic Conditions.” If economic conditions in 
Argentina were to deteriorate, it would likely have an adverse effect on our financial condition and results of operations.  

Our domestic operations are subject to extensive regulation.  

The oil and gas industry is subject to extensive 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 materially and 
adversely affected by regulatory and political changes in Argentina. We currently 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 pass higher domestic taxes or increases in international prices of crude oil and other hydrocarbon 
fuels and exchange rate fluctuations through to domestic prices, or to increase local prices of natural gas (in particular for 
residential customers);  

•   higher taxes on exports of hydrocarbons;  
•   restrictions 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; 
and  

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

The Argentine government has made certain changes in regulations and policies governing the energy sector to give absolute 
priority to domestic supply at low, 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. 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—Regulatory Framework and Relationship with the Argentine Government.” 
Similarly, we cannot assure you that future government policies aimed at sustaining economic recovery or in response to domestic 
needs will not adversely affect the oil and gas industry.  

In January 2007, Law No. 26,197 was enacted, which, in accordance with Article 124 of the National Constitution, provided 
that Argentine provinces shall be the owners of the hydrocarbon reservoirs located within their territories. Pursuant to the law, the 
Argentine Congress is charged with enacting laws and regulations aimed at developing mineral resources within Argentina, while the 
provincial governments are responsible for enforcing these laws and administering hydrocarbon fields that fall within the territories of 
their respective provinces. Certain provincial governments, however, have construed the provisions of Law No. 26,197 and Article 
124 to empower the provinces to enact their own regulations concerning exploration and production of oil and gas within their 
territories. There can be no assurance that regulations or taxes (including royalties) enacted or administered by the provinces will not 
conflict with federal law, and such taxes or regulations may adversely affect our operations and financial condition.  

7 

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

In recent years, due to regulatory, economic and government policy factors, our domestic gasoline, diesel and other fuel prices 

have frequently lagged substantially behind prevailing international and regional market prices for such products, and our ability to 
increase prices has been limited. Likewise, the prices at which we sell natural gas in Argentina (particularly to the residential sector) 
are subject to government regulations and currently are substantially below regional market prices for natural gas. For additional 
information on domestic pricing for our products, see “Item 5. Operating and Financial Review and Prospects” and “Item 4. 
Information on the Company—Regulatory Framework and Relationship with the Argentine Government—Market Regulation.” We 
cannot assure you that we will be able to increase the domestic prices of our products in response to future increases in the 
international market prices of such products, and limitations on our ability to do so would continue to adversely affect our financial 
condition and results of operations. Similarly, we cannot assure you that hydrocarbon prices in Argentina will match the increases or 
decreases in hydrocarbon prices at the international or regional levels.  

We are subject to direct and indirect 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 (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 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 extensive 
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 that 
relieve us from any contingent liability for the failure to comply with our contractual obligations, 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.”  

In addition, the effectiveness of certain of our natural gas export authorizations is subject to an analysis by the Argentine 
Secretariat of Energy of natural gas reserves in the Noroeste basin. The result of such analysis is uncertain and may have an adverse 
impact upon our performance of the export gas sales agreements related to such export authorizations should the Argentine Secretariat 
of Energy determine that reserves are inadequate. See “Item 8. Financial Information—Legal Proceedings—Argentina.”  

Crude oil exports, as well as the export of most of our hydrocarbon products, currently require prior authorization from the 
Argentine Secretariat of Energy (pursuant to the regime established under Resolution S.E. No. 1679/04 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 
fuel must also first demonstrate that the local demand of diesel is duly satisfied. Because domestic diesel production does not currently 
satisfy Argentine domestic consumption needs, we have been prevented since 2005 from selling diesel production in the export 
market, and thereby obliged to sell in the local market at prevailing domestic prices.  

We are unable to predict how long these export restrictions will be in place, or whether any further measures will be adopted 
that adversely affect our ability to export gas, crude oil and diesel fuel or other products and, accordingly, our results of operations.  

The imposition of new export duties and other taxes could adversely affect our results  

Since 2002, new duties have been imposed on exports, and have been progressively increased over the years. Resolution 
394/2007 of the Ministry of Economy and Production, published on November 16, 2007, amended the export duties on crude oil and 
other crude derivative products imposed in previous years. The new regime provides that when the WTI international price exceeds 
the reference price, which is fixed at U.S.$60.9/barrel, the producer shall be allowed to collect at U.S.$42/barrel, with the remainder 
being withheld by the Argentine government as an export tax. If the WTI international price is under the reference price but over 
U.S.$45/barrel, a 45% withholding rate will apply. If such price is under U.S.$45/barrel, the applicable export tax is to be determined 
by the Argentine government within a term of 90 business days. The withholding rate determined as indicated above also currently 
applies to diesel, gasoline and other crude derivative products. In addition, the calculation procedure described above also applies to 
other petroleum products and lubricants based upon different withholding rates, reference prices and prices allowed to producers. See 
“Item 4. Information on the Company—Regulatory Framework and Relationship with the Argentine Government—Market 
Regulation.”  

8 

 
  
With respect to natural gas products, Resolution No. 127/2008 of the Ministry of Economy and Production increased export 

duties applicable to natural gas exports from 45% to 100%, mandating a valuation basis for the calculation of the duty as the highest 
price established in any contract of any Argentine importer for the import of gas. Resolution No. 127/2008 provides with respect to 
LPG products (including butane, propane and blends thereof) that if the international price of the relevant LPG product, as notified 
daily by the Argentine Secretariat of Energy, is under the reference price established for such product in the Resolution (U.S.$338/m3 
for propane, U.S.$393/m3 for butane and U.S.$363/m3 for blends of the two), the applicable export duty for such product will be 
45%. If the international price exceeds the reference price, the producer shall be allowed to collect the maximum amount established 
by the Resolution for the relevant product (U.S.$233/m3 for propane, U.S.$271/m3 for butane and U.S.$250/m3 for blends of the 
two), with the remainder being withheld by the Argentine government as an export tax.  

As a result of the aforementioned export tax increases, we may be and, in certain cases, have already been forced to seek the 
renegotiation of our export contracts, despite, in most cases, the prior authorization of such contracts by the Argentine government. 
We cannot provide assurances that we will be able to renegotiate such contracts on terms acceptable to us.  

The imposition of these export taxes has adversely affected our results of operations. We cannot assure you that these taxes will 

not continue or be increased in the future or that other new taxes will not be imposed.  

We may be exposed to fluctuations in foreign exchange rates  

Our results of operations are exposed to currency fluctuation 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 and may do so in the future. 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 would affect our business.  

We may be subject to exchange and capital controls  

In 2001 and 2002, as a result of the economic crisis, Argentina imposed exchange controls and transfer restrictions substantially 

limiting the ability of companies to retain foreign currency or make payments abroad. Under current Argentine law, exporters are 
required to convert proceeds from export operations into domestic currency, subject to certain exceptions applicable to the oil and gas 
industry that permit us to retain abroad 70% of export proceeds. See “Item 4. Information on the Company—Regulatory Framework 
and Relationship with the Argentine Government—Repatriation of Foreign Currency.” There can be no assurances regarding future 
modifications to exchange and capital controls. The imposition of stricter exchange and capital controls could adversely affect our 
financial condition or results of operations and our ability to meet our foreign currency obligations and execute our financing plans.  

Our access to international capital markets is influenced by the perception of risk in Argentina and other emerging economies, 
which may affect our ability to finance our operations and the trading values of our securities.  

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.  

Risks Relating to the Argentine Oil and Gas Business and Our Business  

Oil and gas prices could affect our level of capital expenditures  

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 related to exploration, development, refining and distribution activities by taking into account, among other 
things, market prices for our hydrocarbon products. In the event that current domestic prices for certain products prevail or decrease, 
our ability to improve our hydrocarbon recovery rates, find new reserves and carry out certain of our other capital expenditure plans is 
likely to be adversely affected, which in turn would have an adverse effect on our results of operations.  

Our reserves and production are likely to decline  

Argentina’s oil and gas fields are mature and our reserves and production are declining as reserves are depleted. In the last two 

years our proved reserves declined by approximately 21.0%, and we replaced approximately 42.1% of our production with new 
proved reserves during 2009; average daily production in 2009, on a boe basis, declined by approximately 7.9% from 2008. We are 
engaged in efforts to mitigate these declines by adding reserves through technological enhancements aimed at improving our recovery 
factors as well as through deepwater offshore exploration and development of tight gas. These efforts are subject to material risks and 
may prove unsuccessful due to risks inherent to the oil and gas industry.

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, among which the most 

important are:  

•   the results of drilling, testing and production after the date of the estimates, which may require substantial revisions;  
•   the quality of available geological, technical and economic data and the interpretation and judgment of such data;  
•   the production performance of reservoirs;  
•   developments such as acquisitions and dispositions, new discoveries and extensions of existing fields and the 

application of improved recovery techniques;  

•   changes in oil and natural gas prices, which could have an effect on the size of our proved reserves because the 

estimates of reserves are calculated under existing economic conditions when such estimates are made. A decline in the 
price of oil or gas could make reserves no longer economically viable to exploit and therefore not classifiable as 
proved; and  

•   whether the prevailing tax rules, other government regulations and contractual conditions will remain the same as on 
the date estimates are made. Changes in tax rules and other government regulations could make reserves no longer 
economically viable to exploit.  

Many of the factors, assumptions and variables involved in estimating proved reserves are beyond our control and are subject to 

change over time. See “Item 4. Information on the Company—Exploration and Production—Oil and Gas Reserves.” Consequently, 
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, leading to increased depreciation, depletion and amortization charges and/or impairment 
charges, which would reduce earnings and shareholders’ equity.  

The oil and gas industry is subject to particular economic 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, and 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, oil or natural gas spills or leaks, 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. If these risks 
materialize, we may suffer substantial operational losses and disruptions to our operations and harm to our reputation. 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 net 
revenues to return a profit after drilling, operating and other costs are taken into account.  

Argentine oil and gas production concessions and exploration permits are subject to certain conditions and may not be renewed  
The Hydrocarbons Law provides for oil and gas concessions to remain in effect for 25 years as from the date of their award, and 
further provides for the concession term to be extended for up to 10 additional years, subject to terms and conditions approved by the 
grantor at the time of the extension. The expiration of part of our and other Argentine oil companies’ concessions occurs in 2017. 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 the extension, any concessionaire and permit holder must have complied with its obligations under the 
Hydrocarbons Law and the terms of the particular concession or permit, including evidence of payment of taxes and royalties, the 
supply of the necessary technology, equipment and labor force and compliance with various environmental, investment and 
development obligations. Under the Hydrocarbons Law, non-compliance with these obligations and standards 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. Concessions representing approximately 50% of our proved reserves as of December 31, 2009 have been 
extended prior to the date of this annual report (see Note 10(c) to our Audited Consolidated Financial Statements). We cannot provide 
assurances that concessions that have not yet been renewed will be extended or that additional investment, royalty payment or other 
requirements will not be imposed on us in order to obtain extensions. The termination of, or failure to obtain the extension of, a 
concession or permit could have a material adverse effect on our business and results of our operations.  

10 

 
   
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, which are typically auctioned by 
governmental authorities, especially those areas with the most attractive crude oil and natural gas reserves. Some provinces of 
Argentina, including La Pampa, Neuquén and Chubut, have created provincial government-owned companies to develop activities in 
the oil and gas industry. Energía Argentina S.A. (ENARSA), the Argentine state-owned energy company, has also entered the market, 
particularly in the context of offshore exploration. As a result, the conditions under which we are able to access new exploratory or 
productive areas could be adversely affected.  

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

Our operations, like those of other companies in the oil and gas industry, are subject to a wide range of environmental, health 

and safety laws and regulations in the countries in which we operate. These laws and regulations have a substantial impact on our 
operations and those of our subsidiaries, and could result in material adverse effects on our financial position and results of operation. 
A number of events related to environmental, health and safety matters, including changes in applicable laws and regulations, adverse 
judicial or administrative interpretations of such laws and regulations, changes in enforcement policy, the occurrence of new litigation 
or development of pending litigation, and the development of information concerning these matters, could result in new or increased 
liabilities, capital expenditures, reserves, losses and other impacts that could have a material adverse effect on our financial condition 
and results of operations. See “Item 8. Financial Information—Legal Proceedings,” “Item 4. Information on the Company—
Regulatory Framework and Relationship with the Argentine Government—Argentine Environmental Regulations” and “Item 4. 
Information on the Company—Regulatory Framework and Relationship with the Argentine Government—U.S. Environmental 
Regulations.” Environmental, health and safety regulation and jurisprudence in Argentina is developing at a rapid pace and no 
assurance can be provided that such developments will not increase our cost of doing business and liabilities. 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. If 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.  

We are party to a number of 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 reserves we have established.  

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.  

We could be subject to organized labor action  

Although we consider our current relations with our workforce to be good, we have experienced 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. 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 during 2008 and 2009. See “Item 
5. Operating and Financing Review and Prospects—Factors Affecting Our Operations—Macroeconomic conditions.”  

Risks Relating to Our Class D Shares and ADSs  

Our principal shareholder can exercise control over the company  

Following the Petersen Transaction, as defined in “Item 7. Major Shareholders and Related Party Transactions” Repsol YPF 

controls 84.04% of our capital stock and voting rights and Petersen Energía S.A. (“Petersen Energía”) and Petersen Energía Inversora 
S.A. (“PEISA”, and together with Petersen Energía, the “Petersen Group”) control 15.46% of our shares and voting rights, in each 
case subject to the shareholders’ agreement described below. In addition, Repsol YPF has granted certain affiliates of Petersen Energía 
(in particular, Enrique Eskenazi, Sebastián Eskenazi, Ezequiel Eskenazi Storey and Matías Eskenazi Storey, shareholders of Petersen 
Energía, or to companies that are, directly or indirectly, wholly-controlled by any of them) an option to purchase an additional 10% of 

11 

 
  
our capital stock held by Repsol YPF. A number of YPF corporate matters are subject to the voting and other procedures set forth in a 
shareholders’ agreement entered into between Repsol YPF, certain affiliates of Repsol YPF and Petersen Energía. Repsol YPF will be 
able to determine substantially all other matters requiring approval by a majority of our shareholders, including the election of a 
majority of our directors. Subject to the terms of the shareholders’ agreement, Repsol YPF will also direct our operations and may be 
able to cause or prevent a change in our control. See “Item 7. Major Shareholders and Related Party Transactions—Shareholders’ 
Agreement.” Repsol YPF’s and the Petersen Group’s interests may differ from those of our other shareholders.  

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 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. The interests of our Class A shareholder, the Argentine government, may 
differ from those of our other shareholders, and, as result, we may not be able to undertake certain transactions on terms that are 
advantageous to our other shareholders or at all.  

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.”  

Active markets may not develop for our Class D shares or the ADSs  

As of the date of this annual report, less than 0.5% of our capital stock is held by non-affiliates. As a result, the public markets 

for our Class D shares and ADSs have had limited trading volume. Although the ADSs will continue to be listed on the NYSE and the 
underlying Class D shares will continue to be listed on the BASE, we cannot assure you that more active and liquid markets will 
develop or of the price at which the Class D shares or the ADSs may be sold.  

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  

Argentine law currently permits the government to impose temporary restrictions on capital movements in circumstances where 

a serious imbalance develops in Argentina’s balance of payments or where there are reasons to foresee such an imbalance. Although 
the transfer of funds abroad in order to pay dividends currently does not require Central Bank approval, restrictions on the movement 
of capital to and from Argentina such as those that previously existed during the recent economic crisis could, if reinstated, 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. We cannot assure you that the Argentine government will not take such 
measures in the future.  

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 restrictions 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.  

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  

Repsol YPF owns Class D shares and ADSs representing a significant majority of our capital stock (which may be reduced by 

10% if the Second Petersen Option described under “Item 7. Major Shareholders and Related Party Transactions—Option 
Agreements” is exercised). The Petersen Group owns ADSs representing up to approximately 15.46% of our capital stock (which may 
be increased up to approximately 25.46% if the Second Petersen Option is exercised). In addition, as described in greater detail under 
“Item 7. Major Shareholders and Related Party Transactions—Registration Rights and Related Agreements,” we have filed and 
undertaken to maintain an effective shelf registration statement for the benefit of the lenders under the senior secured term loan facility 

12 

 
  
provided to Petersen Energía to enable it to enter into the Petersen Transaction (as defined in “Item 7. Major Shareholders and Related 
Party Transactions”). The lenders under the senior secured term loan facility, upon the acceleration of such facility following the 
occurrence and continuation of an event of default under such facility, will be able to freely sell up to approximately 15% of our 
outstanding capital stock (which may be increased to approximately 25% if the Second Petersen Option is exercised) under the shelf 
registration statement. Sales of a substantial number of Class D shares or ADSs by Repsol YPF, the Petersen Group, such lenders or 
any other future significant shareholder, or the anticipation of such sales, could decrease the trading price of our Class D shares and 
the ADSs. See “Item 7. Major Shareholders and Related Party Transactions.”  

You may be unable to exercise preemptive, accretion or other rights with respect to the Class D shares underlying your ADSs  
You may not be able to exercise the preemptive or accretion rights relating to the shares underlying your 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, you may receive only the net proceeds from the sale of your 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 Superintendency of Corporations (Inspección General de Justicia, or “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 your ADSs. As a 

holder of ADRs representing the ADSs being held by the depositary in your name, you 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 BASE, 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 fluctuated significantly against many major world currencies, including the U.S. dollar. A depreciation 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.  
History and Development of YPF  

Information on the Company  

Overview  

YPF is a limited liability company (sociedad anónima), incorporated under the laws of Argentina for an unlimited 

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”.  

13 

 
  
   
We are Argentina’s leading energy company, operating a fully integrated oil and gas chain with leading market 
positions across the domestic upstream and downstream 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. In 2009, we had consolidated net sales of Ps.34,320 million (U.S.$9,032 
million) and consolidated net income of Ps.3,486 million (U.S.$917 million).  

Most of our predecessors were state-owned companies with operations dating back to the 1920s. 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.  

Since 1999, we have been controlled by Repsol YPF, an integrated oil and gas company headquartered in Spain with global 
operations. Repsol YPF owned approximately 99% of our capital stock from 2000 until 2008, when the Petersen Group purchased, in 
different stages, shares representing 15.46% of our capital stock. In addition, Repsol YPF granted certain affiliates of Petersen Energía 
an option to purchase up to an additional 10% of our outstanding capital stock. This option will expire on February 21, 2012. See 
“Item 7. Major Shareholders and Related Party Transactions.”  

Upstream Operations  

•   We operate more than 70 oil and gas fields in Argentina, accounting for approximately 39% of the country’s total production 
of crude oil, excluding natural gas liquids, and approximately 39% of its total natural gas production, including natural gas 
liquids, in 2009, according to information provided by the Argentine Secretariat of Energy.  

•   We had proved reserves, as estimated as of December 31, 2009, of approximately 538 mmbbl of oil and 2,672 bcf of gas, 

representing aggregate reserves of 1,013 mmboe.  

•   In 2009, we produced 111 mmbbl of oil (302 mbbl/d) and 533 bcf of gas (1,460 mmcf/d).  

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). We also have a 50% 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, 2009 consisted of 1,632 YPF-branded 

service stations, which we estimate represented approximately 30.9% of all 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 and Plaza Huincul sites. In addition, Profertil S.A. (“Profertil”), a company that we jointly 
control with Agrium Investments Spain S.L. (“Agrium”), is one of the leading producers of urea in the Southern Cone.

The Argentine Market  

Argentina is the second largest producer of natural gas and the fourth largest producer of crude oil in Latin America based on 

2008 production, according to the BP Statistical Review.  

In response to the economic crisis of 2001 and 2002, the Argentine government, pursuant to the Public Emergency Law (Law 

No. 25,561), 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, heightening domestic 
demand for such products. In the case of natural gas, the price at which Bolivia exports natural gas to Argentina was approximately 
U.S.$6.16/mmBtu in December 2009 and in March 2010, while our average sales price in Argentina during 2009 was approximately 
U.S.$1.86/mmBtu.  

Argentina’s gross domestic product, or GDP, has grown at an average annual real rate of approximately 8.5% from 2003 to 
2008, after declines during the economic crisis of 2001 and 2002. Driven by this economic expansion and low domestic prices, energy 
demand has increased significantly during the same period, outpacing energy supply (which in the case of oil declined). For example, 
Argentine natural gas and diesel consumption grew at average annual rates of 6.7% and 4.7%, respectively, during the period 2003-
2008, according to the BP Statistical Review and the Argentine Secretariat of Energy. As a result of this increasing demand and 
actions taken by the Argentine regulatory authorities to support domestic supply, exported volumes of hydrocarbon products, 
especially natural gas, diesel and gasoline, declined steadily over this period. At the same time, Argentina has increased hydrocarbon 
imports, becoming a net importer of certain products, such as diesel, and increased imports of gas (including NGL). In 2003, 
Argentina’s net exports of diesel amounted to approximately 1,349 mcm, while in 2009 its net imports of diesel amounted to 
approximately 545 mcm, according to information provided by the Argentine Secretariat of Energy. Significant investments in the 
energy sector are expected to be required in order to support continued economic growth, as the industry is currently operating near 
capacity.  

Demand for diesel in Argentina exceeds domestic production. In addition, the import prices of refined products have been 

substantially higher than the average domestic sales prices of such products, rendering the import and resale of such products 
uneconomic. As a result, service stations experience temporary shortages and are required to suspend or curtail diesel sales. While we 
are operating our refineries at or above capacity, during peak demand periods we are forced to prorate supplies among our service 
stations according to historical sales levels.  

As the largest integrated oil and gas company in Argentina, we believe that we are well positioned to benefit from potential 

reform in the energy sector, although we cannot assure that reforms will be implemented or, if implemented, that they will be 
advantageous to our business.  

History of YPF  

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, Law No. 24,145 (referred to as the Privatization Law), which established the procedures by which we were 

to be privatized, was enacted. 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 percentage 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 in block (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.  

Between 2004 and 2005 we made non-strategic asset divestitures totaling U.S.$239.5 million.  

17 

 
  
On February 21, 2008, Petersen Energía purchased 58,603,606 of our ADSs, representing 14.9% of our capital stock, from 
Repsol YPF for U.S.$2,235 million. In addition, Repsol YPF granted certain affiliates of Petersen Energía options to purchase up to an 
additional 10.1% of our outstanding capital stock within four years. On May 20, 2008, PEISA exercised an option to purchase shares 
representing 0.1% of our capital stock. Additionally, PEISA launched a tender offer to purchase all of the shares of YPF that were not 
already owned by them at a price of U.S.$49.45 per share or ADS. Repsol YPF, pursuant to its first option agreement with Petersen 
Energía, had stated that it would not tender YPF shares to PEISA. A total of 1,816,879 shares (including Class D shares and ADSs), 
representing approximately 0.462% of our total shares outstanding, were tendered. Repsol YPF owns a majority of our capital stock 
and, subject to the shareholders’ agreement entered into between Repsol YPF and Petersen Energía, is able to determine substantially 
all issues decided by our shareholders. See “Item 7. Major Shareholders and Related Party Transactions.”  

Business Segments  

We organize our business along the following segments:  
•   Exploration and Production;  
•   Refining and Marketing; and  
•   Chemicals.  

The Exploration and Production segment’s sales to third parties in Argentina and abroad include sales of natural gas and 
services fees (primarily for the transportation, storage and treatment of hydrocarbons and products). In addition, crude oil produced by 
us in Argentina, or received from third parties in Argentina pursuant to service contracts, is transferred from Exploration and 
Production to Refining and Marketing at transfer prices established by us, which generally seek to approximate Argentine market 
prices.  

The Refining and Marketing segment purchases crude oil from the Exploration and Production segment and from third parties. 
Refining and Marketing activities include crude oil refining and transportation, as well as the marketing and transportation of refined 
fuels, lubricants, LPG, compressed natural gas and other refined petroleum products in the domestic wholesale and retail markets and 
the export markets.  

The Chemicals segment sells petrochemical products both in the domestic and export markets.  

Additionally, we record certain assets, liabilities and costs under the Corporate and Other segment, including corporate 

administration costs and assets and certain construction activities.

(1)  Net sales are net to us after payment of a fuel transfer tax, turnover tax and customs duties on exports. 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 in determining net sales. 
See “—Exploration and Production—Oil and gas production, production prices and production costs” and Note 2 (f) to the 
Audited Consolidated Financial Statements.  
Includes exploration and production operations in Argentina and the United States.  
Intersegment sales of crude oil to Refining and Marketing are recorded at transfer prices established by us, which generally seek 
to approximate Argentine market prices.

(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 YPF owns a working interest.  
(4) 
(5)  The United States only.  

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

Argentine properties  
Argentina is the fourth largest hydrocarbon producing nation in Latin America and the fourth largest in terms of reserves, after 

Mexico, Venezuela and Brazil based on 2008 data, according to the 2008 edition of BP Statistical Review of World Energy, published 
in June 2009 (the “BP Statistical Report”). 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. According to the BP Statistical Report, a 
total of 23 sedimentary basins have been identified in the country. Six of these are combined onshore/offshore and three are entirely 
offshore. Argentina’s total onshore acreage is composed of approximately 421 million acres, and total offshore acreage consists of 
176 million acres on the South Atlantic shelf within the 200-meter depth line. A substantial portion of the country’s estimated 
571 million acres in sedimentary basins has yet to be evaluated by exploratory drilling. Commercial production is concentrated in five 
basins: Neuquina, Cuyana and Golfo San Jorge in central Argentina, Austral in southern Argentina (which includes onshore and 
offshore fields), and the Noroeste basin in northern Argentina. The Neuquina and Golfo San Jorge basins are the most significant 
basins for our activities in Argentina.  

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

2009:

In addition to productive oil and gas wells located in Argentina, we have interests in oil wells located in the United States (7 
gross wells and 1 net well, as of December 31, 2009).  

(2)  A “gross well” is a well in which YPF owns 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.  
(3)  Gross and net wells include one oil well and three gas wells with multiple completions.

Approximately 86% of our proved crude oil reserves in Argentina are concentrated in the Neuquina (54%) and Golfo San Jorge 

(32%) basins, and approximately 95% of our proved gas reserves in Argentina are concentrated in the Neuquina (73%), Noroeste 
(16%) and Austral (6%) basins.  

As of December 31, 2009, YPF held 107 production concessions and exploration permits in Argentina. YPF directly operates 71 

of them, including 61 production concessions and 10 exploration permits.  

As of December 31, 2009, YPF held 16 exploration permits in Argentina, 11 of which are onshore exploration permits and five 
of which are offshore exploration permits. YPF has 100% ownership of three onshore permits, and its participating interests in the rest 
vary between 50% and 63%. YPF’s interests in the offshore permits vary between 30% and 35%.  

As of December 31, 2009, YPF had 91 production concessions in Argentina. YPF has a 100% ownership interest in 54 
production concessions, and its participating interests in the remaining 37 production concessions vary between 12.2% and 98%.  

Joint ventures and contractual arrangements in Argentina. We participate in 13 exploration and 25 production joint ventures 

and contractual arrangements (18 of them not operated by YPF) in Argentina. Our interests in these joint ventures and contractual 
arrangements range from 12.2% to 98%, and our obligations to share exploration and development costs vary 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 participate, see Note 6 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.

International properties  
As of December 31, 2009, we had mineral rights in 63 blocks in the United States, comprised of 58 exploratory blocks, with a 

net surface area of 857 square kilometers and five development blocks, with a net surface area of 17 square kilometers. Our U.S. 
subsidiaries’ net proved reserves in the United States as of December 31, 2009 were 1.4 mmboe. Our U.S. subsidiaries’ net petroleum 
production in the United States for 2009 was 1.0 mmboe.  

The Neptune Field is located approximately 120 miles from the Louisiana coast within the deepwater region of the Central Gulf 
of Mexico. The unitized field area comprises Atwater Valley Blocks 573, 574, 575, 617 and 618. Our indirect subsidiary, Maxus U.S. 
Exploration Company, has a 15% working interest in the field. The other joint venture participants are BHP Billiton (35%), Marathon 
Oil Corp. (30%) and Woodside Petroleum Ltd (20%). BHP Billiton is the operator of the Neptune Field and the associated production 
facilities. The Neptune reserves are being produced using a standalone, tension leg platform (TLP) located in Green Canyon Block 
613 within 4,230 feet of water. Production began on July 8, 2008. The platform supports seven sub-sea development wells which are 
tied back to the TLP via a subsea gathering system.  

In 2009, YPF Holdings Inc. (“YPF Holdings”) participated in the drilling of the Northwood exploration prospect in the Gulf of 

Mexico with a net interest of 3.5%. YPF Holdings’ total net investment was U.S.$11 million. No reserves were found.  

In addition, YPF Holdings has entered into various operating agreements and capital commitments associated with the 

exploration and development of its oil and gas properties. Such contractual, financial and/or performance commitments are not 
material, except for commitments related to the Neptune Project located in the vicinity of the Atwater Valley Area, Blocks 573, 574, 
575, 617 and 618. Total commitments remaining as of December 31, 2009 for the Neptune Project are capital expenditures of 
U.S.$1.3 million and minimum pipeline transportation payment obligations of U.S.$16.3 million.  

Additionally, as of December 31, 2009, we held through YPF Guyana Ltd, a wholly-owned subsidiary of YPF International, 

S.A., an undivided participating interest of 30% in a petroleum prospecting license (the “Petroleum Prospecting License”) and a 
petroleum agreement (the “Petroleum Agreement”) in Guyana, with a surface exploratory area attributable to our working interest of 
2,520 square kilometers, which represents approximately 622.7 thousand undeveloped acres. The renewal of the Petroleum 
Prospecting License took place on November 25, 2009 and it was granted by the Guyana government for three years. In accordance 
with the Petroleum Agreement, the start of a new renewal period implied a relinquishment of 930 square kilometers (according to our 
30% interest) of the Georgetown exploration block (offshore Guyana), as well as the drilling of an exploratory well, in respect of 
which we have committed to make capital expenditures of U.S.$32.4 million (according to our undivided interest of 30% in that 
exploration block). Drilling of the exploratory well must commence before May 25, 2011.  

The main exploration activities performed during 2009 were the acquisition and primary processing of 3D seismic data for 
1,850 square kilometers. Additionally, the seismic data was re-processed using pre-stack depth migration. Regional and detailed 
geological studies and field and well data were analyzed to assess the potential of the Georgetown block. These studies led to the 
definition of the Jaguar 1 prospect, considered the main exploration target of the block. During 2010, the exploration activities will be 
focused on the final prospect coordinates and depth definition, followed by well planning and pre-drilling activities (such as rig 
contract bidding, the acquisition of long lead items and conducting site surveys).  

Our operations in the United States, through YPF Holdings, are subject to certain environmental claims. See “—Environmental 

Matters—YPF Holdings—Operations in the United States.”  

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.  

In accordance with the SEC’s new rules, information on net proved reserves as of December 31, 2009 (including for the 
calculation of unit-of-production depreciation rates and the standardized measure of discounted net cash flow) was calculated using 
the average price during the 12-month period ending on December 31, 2009, determined as an unweighted average of the first-day-of-
the-month price for each month of that period. Information on net proved reserves as of December 31, 2008 and 2007 was calculated 
using year-end prices and costs, respectively.  

22 

 
  
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, we exclude from our 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 our reported reserves despite the fact that such payments are referred to as “royalties” under local rules. We follow the same 
methodology 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 crude oil and natural gas liquids.  

YPF’s estimated proved reserves as of December 31, 2009 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, surface geological 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.  

The use of new reliable technology as well as the change to an average of the first-day of the month prices from year-end prices 

to calculate proved reserves did not have any material impact on YPF’s proved reserves volumes in 2009.  

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

audits.”

The paragraphs below explain in further detail the most significant changes in our reserves during 2009.  

1. 

Changes in our estimated proved reserves during 2009  
Revisions of previous estimates  
During 2009, our proved reserves were revised upwards by 40 mmbbl of oil and 36 bcf of gas.  

The main revisions to proved reserves have been due to:  
•   A total of 28 mmboe were added as proved reserves in the Ramos, Barranca Baya, Los Perales, Chihuido de La Salina, 
Manantiales Behr, Seco León, Las Heras, Cañadón Yatel and Escalante areas, mainly as a result of better than expected 
production and new development projects.  

•   A total of 11 mmboe were added to net proved reserves as a result of the extension of our concession contracts concerning 

the San Roque, Lindero Atravesado and Aguada Pichana fields, which were extended for 10 years (until 2027).  

•   Changes in economic conditions (in particular, increasing oil prices), resulted in upward adjustments of 7 mmboe in proved 
reserves in some exploitation areas such as Puesto Molina and Cañadón Amarillo. This revision includes the booking of 
development projects in undeveloped proved reserves areas where exploitation would not have been economically viable 
under 2008 year-end oil prices.  

•   In the San Roque field, 7 mmboe of proved reserves were added and 28 mmboe of proved undeveloped reserves were 
transferred to the developed category, as a result of the successful production performance of development projects.  
•   An addition of 3 mmboe of proved reserves was made as a result of successful workover jobs performed in some areas, 

mainly in Chihuido de La Salina, Los Cavaos and Los Perales fields.  

•   The results of our development wells were below expectations in some areas, resulting in a downward revision of 9 mmboe 

of proved reserves, mainly in Loma La Lata field.  

•   New reservoir studies and changes in our development projects resulted in a net reduction of 7 mmboe in proved reserves in 

the Acambuco field.  

2. 

Improved recovery  
In the Golfo de San Jorge and Neuquina basins, 10 mmbbl of proved oil reserves have been added on account of the completion 

of technical/economic feasibility studies on extensions of current improved recovery projects, scheduled to be implemented between 
2010 and 2014, mainly in Aguada Toledo—Sierra Barrosa, Los Perales and Seco León.  

A total of 5 mmbbl of proved oil reserves have been added due to positive production response, well repairs, and new 
production and injection wells drilled as part of the improved recovery projects, mainly in the Chihuido La Salina, Señal Picada, 
Desfiladero Bayo and CNQ 7A fields.  

3. 

Extensions and discoveries  
A total of 27 mmboe (68 bcf of gas and 15 mmbbl of oil) of proved reserves have been added as a result of drilling in unproved 
reserves areas during 2009 (in particular in the San Roque, Manantiales Behr, Loma La Lata, Barranca Baya, Aguarague, Seco León, 
Cañadón Yatel and Desfiladero Bayo fields).  

Exploratory activities in Bandurria (in the Neuquina basin) were successful with the completion of the exploratory well La 

Caverna X-1, adding 0.1 mmboe.  

Changes in our proved undeveloped reserves during 2009  
YPF had estimated net proved undeveloped reserves of 211 mmboe at December 31, 2009, which represented 20.8% of our 
1,013 mmboe total reported proved reserves as of such date. This compares to estimated net proved undeveloped reserves of 286 
mmboe at December 31, 2008 (25% of the 1,133 mmboe total reported proved reserves as of such date). This 26% decrease in net 
proved undeveloped reserves in 2009 was principally due to the implementation of development programs which resulted in the 
transfer of approximately 81 mmboe from proved undeveloped to proved developed reserves during such year. The largest transfers 
were associated with the drilling activity in development projects and the installation of compression facilities in the Loma La Lata, 
Sierras Blancas and San Roque gas fields. On the other hand, newly approved projects and revisions of previous estimates resulted in 
a net addition of 6 mmboe in proved undeveloped reserves for this period.  

YPF’s total expenditure to advance the development of reserves during 2009 was approximately U.S.$738 million, of which 

U.S.$125 million was allocated to projects that resulted in a transfer of proved undeveloped to proved developed reserves during the 
year.  

26 

 
  
  
As at December 31, 2009, 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 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, and aligned with the control of quality of reserves booking of Repsol YPF. This process to manage reserves booking is centrally 
controlled and has the following components:  

(a)  The Reserves Control Direction (RCD) is separate and independent from the Exploration and Production segment. RCD’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 RCD is to 
ensure that YPF’s proved reserves estimates and disclosure are in compliance with the rules of the SEC, the Financial 
Accounting Standard Board (FASB), and the Sarbanes-Oxley Act, and to review annual changes in reserves estimates and 
the reporting of YPF’s proved reserves. The RCD is responsible for preparing the information to be publicly disclosed 
concerning YPF’s reported proved reserves of crude oil and natural gas. The RCD 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 RCD 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 RCD are registered with or affiliated to the relevant professional bodies in their 
fields of expertise.  

(b)  The Reserves Control Director, head of the RCD, who is responsible for overseeing the preparation of the reserves 

estimates. The current director has over 30 years of experience in reservoir-engineering, geology and geophysics, reserves 
estimates, project development, finance and general accounting regulation and with well-rounded exposure to 
international operations. Over the past three years, he has been responsible for supervision over YPF’s governance and 
compliance procedures in respect of reserves estimates. He is an active member of the Society of Petroleum Engineers 
(SPE) and serves on its Editorial Committee for Reservoir Engineering and Evaluation. In addition, he holds a petroleum 
engineering degree from Universidad Central de Venezuela, MSc and PhD degrees in petroleum engineering from 
Pennsylvania State University in the United States, and an MBA from Instituto de Estudios Avanzado de Administración 
in Venezuela. Consistent with our internal control system requirements, the Reserves Control Director’s compensation is 
not affected by changes in reported reserves.  

(c)  A quarterly internal review by the RCD of changes in proved reserves submitted by the Exploration and Production 
business unit and associated with properties where technical, operational or commercial issues have arisen.  

(d)  The Quality Reserve Coordinator (QRC), who is a professional assigned at each Exploration and Production business unit 

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 

27 

 
  
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 10 years of practical experience in petroleum engineering or petroleum production geology, with at least five 
years of such experience in charge of the estimate and evaluation of reserves information, 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, which examines the effectiveness of YPF’s financial controls, designed to ensure the reliability of 
reporting and safeguarding of all the assets and examining 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 

i. 

ii. 

party reserves audit in any given year are selected on the following basis:  
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 third party reserves audit, YPF’s proved reserves figures have to be within 7% 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 reestimate its proved reserves to achieve this tolerance level or should disclose the 
third party figures.  

In 2009, Gaffney, Cline & Associates Inc. audited the areas not operated by YPF in the Austral, Golfo San Jorge, Neuquina and 

Noroeste basins. All these third party audits were performed, as of September 30, 2009 on fields which, in our estimates as of such 
date, contained proved reserves of 242 mmboe in the aggregate, and cumulatively covered 21% of our proved reserves in Argentina as 
of that date. A copy of the related reserves audit report is filed as an Exhibit to this annual report.  

We are required, in accordance with Resolution S.E. No. 324/06 of the Argentine Secretariat of Energy, to file annually and by 
March 31 of every year details of our estimates of our oil and gas reserves and resources with the Argentine Secretariat of Energy, as 
defined in that resolution and certified by an external auditor. The aforementioned certification and external audit only have the 
meaning established by Resolution S.E. No. 324/06, 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, 2009 and the estimates of our proved oil and 
gas reserves filed with the Argentine Secretariat of Energy 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 Energy 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 Energy includes other categories of reserves and resources different to proved reserves that are not included in this 
annual report, which contains estimates of proved reserves consistent with the SEC’s guidance; and (iii) the definition of proved 
reserves under Resolution S.E. No. 324/06 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 oil (including crude oil, condensate and natural gas liquids) and gas production on an as sold 
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.

(2)  Loma La Lata field in Argentina contains over 15% of our total proved reserves expressed on an oil-equivalent barrels basis. Oil 

production in this field was 17, 16 and 17 mbbl for the years ended December 31, 2009, 2008 and 2007, respectively. Natural 
gas production in Loma La Lata field was 207, 238 and 262 bcf for the years ended December 31, 2009, 2008 and 2007, 
respectively.  

(3)  Oil production for the years 2009, 2008 and 2007 include an estimated approximately 12, 14 and 14 mmbbl, respectively, of 

crude oil, condensate and natural gas liquids in respect of royalty payments which are a financial obligation, or are substantially 
equivalent to a production or similar tax.  

(4)  Natural gas production for the years 2009, 2008 and 2007 includes an estimated approximately 54, 69 and 72 bcf, respectively, 
of natural gas, in respect of royalty payments which are a financial obligation, or are substantially equivalent to a production or 
similar tax.  

In 2009, crude oil and natural gas production, on a boe basis, decreased by 8% compared to 2008. As compared to 2008, crude 

oil (including condensate and natural gas liquids) production (including production from our foreign operations) decreased by 3.5% in 
2009. With respect to natural gas, production decreased by 12.2% in 2009 compared to 2008.  

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.

In addition to wells drilled in Argentina, we participated in the drilling of the following “gross” wells in North America: one dry 
exploratory well in 2009 and seven development wells during the last three years, five of which were productive. “Net” wells 
drilled in North America round to less than one well.  
“Gross” wells include all wells in which we have an interest. “Net” wells equals gross wells after deducting third party interests.  
Includes four wells which remained under evaluation as of December 31, 2009.  

Activities in Argentina  
During the past three years our main exploratory activities in Argentina have had the following principal focuses:  

Offshore :  

•   Shallow water. In October 2008, YPF initiated a shallow water drilling campaign using the Ocean Scepter Jack Up. The first 
exploratory well, Aurora x-1, was drilled between October and December 2008 in the GSJM-1 block (operated by us and in 
which we have a 67.0% working interest and Petrobras Energía S.A. (“PESA”) has a 33.0% working interest). Between 
February and July 2009, three more wells were drilled in the GSJM-1 block: Elizabeth x-1, Alicia x-1 and Silvia x-1. While 
all these wells recovered hydrocarbons, they were abandoned as subcommercial discoveries. During 2009, YPF also drilled 
wells Helix x-1, x-2 and x-3 in block E2 (operated by ENAP Sipetrol (33.0%), and in which YPF and ENARSA each have a 
33.0% working interest). All three wells were abandoned as dry holes.  

•   Deep water. YPF currently operates two projects at a well planning stage: the Malvinas Project in blocks CAA40/CAA46 at 
a water depth of 500 meters (operated by us and in which we hold a 33.5% working interest and in which PESA and Pan 
American Energy (“PAE”) have working interests of 33.5% and 33.0%, respectively) and the Colorado Marina Project in 
block E1 at a water depth of 1,500 meters (operated by us and in which we hold a 35.0% working interest and in which 
PESA, ENARSA and Petrouruguay, S.A., have working interests of 25.0%, 35.0% and 5.0%, respectively).

Onshore: YPF continued its near-field exploration activity in its concession blocks, explored for deep gas in the Noroeste and 
Neuquina basins and embarked on three new exploratory fronts:  

•   Shale gas. The first shale gas well ever drilled in Argentina (PSG x-2 in the Loma La Lata Block) was spudded in November 

2009 and is expected to be completed in 2010.  

•   Quintuco formation. New exploratory concepts have been developed for this traditional reservoir (Quintuco Formation 

Carbonates). Two discovery wells were drilled in 2009 (La Caverna x-1 and La Dolina x-1). La Caverna x-1 (in which we 
have a 54.54% working interest) is located in the Bandurria block and is operated by us. La Dolina x-1 (in which we have a 
100% working interest) is located in the Loma La Lata block and is under evaluation. YPF is planning to continue with this 
program with three additional wells in 2010.  

•   Frontier areas. Two seismic acquisition programs were completed in remote underexplored areas (Río Barrancas and 

Tamberías Blocks, in which we have a 100% working interest). A total of 164 km2 of 3D seismic and 441 km of 2D seismic 
were recorded in these two areas.  

During 2009, YPF completed 17 exploratory wells in Argentina: seven in the Neuquina basin, four in the Golfo San Jorge basin 

(three of them, offshore) and six in the offshore Austral basin. Three out of the 17 wells were discoveries.  

During this year, we continued improving our facilities and optimizing our oil and gas properties and production. In the case of 
our U.S.$13 million 6th Stage Low Pressure Compression Project at the Loma La Lata natural gas field, there was gas production and 
wellhead pressure above the initial forecast. New reservoir and facilities simulations will be made during 2010, before continuing the 
compression and surface facilities optimization.  

Our key production asset capital improvement projects during 2009 included a water injection project at Rincón de los Sauces in 

the Neuquina basin, in the Chihuido de la Sierra Negra field, to mitigate the natural production decline attributable to the maturity of 
that field. This project was completed in 2009 at a total cost of approximately U.S.$115 million. In the year 2009, we drilled 8 new 
wells to replace collapsed wells in Chihuido de la Sierra Negra.  

A pilot project study that evaluates the Water Alternating Gas (WAG) process in Chihuido de la Sierra Negra has already been 
completed, concluding that an expansion was not economically feasible. Our current effort is focused on evaluating the Enhanced Oil 
Recovery (EOR) opportunities by chemical methods (Surfactant Polymer, or SP). Delineation and development work has been 
focused on Manantiales Behr, Cañadón Yatel, Barranca Baya, Desfiladero Bayo, Señal Picada and Cañadón Amarillo. Tight gas 
opportunities are being evaluated through a pilot project study in the Lajas formation, in the Cupen Mahuida area. Significant work is 
being devoted to optimizing the secondary waterflooding recovery factor through simulation models by zone in Chihuido de la Sierra 
Negra, Los Perales and Cañadón Seco-Cañadón León.  

In block CNQ7A, operated by Pluspetrol Energy S.A. (“Pluspetrol”), in which we have a 50% working interest, the delineation 

of the El Corcobo Norte, Jagüel Casa de Piedra, Cerro Huanunl Sur and Puesto Pinto Reservoirs has been completed and the 
development of those reservoirs has begun. Steam and water injection pilot projects in Cerro Huanunl Sur have ended with better 
results for the water injection recovery method than the steam injection project.  

In October 2008, eight of our concessions in the province of Neuquén were extended for 10 years (up to the year 2027): Cerro 

Bandera, Señal Cerro Bayo, Chihuido de la Sierra Negra, El Portón, Filo Morado, Octógono and Señal Picada-Punta Barda (100% 
owned and operated by YPF), and Puesto Hernández (operated by another company, and in which YPF has a 61.55% working 
interest).  

We have also extended the term of the concessions of blocks Lindero Atravesado (in which we have a 37.5% working interest) 

until 2026, and block Aguada Pichana (27.27% working interest) and San Roque (34.11% working interest) until 2027.  

Our production declines in recent periods are attributable mainly to the continuing maturity of our fields, although work 
stoppages and pipeline issues have on occasion contributed to production declines and capital project delays. During 2009, a series of 
labor and community conflicts resulted in lost production of approximately 4.9 mmboe.  

Our technical staff is still engaged in efforts to mitigate the decline in reserves and production through field delineation and 

near-field exploration to add reserves and focused water injection and geologically-optimized infill drilling aimed at improving 
recovery factors in producing assets. This initiative started in late 2006 with the Plan de Desarrollo de Activos (Asset Development 
Program or “PLADA”), following a rigorous project management methodology. During 2009 some 2008 PLADA projects were still 
in progress, adding value to static and dynamic models.  

Our project portfolio, updated in June 2009, included 1,440 projects to develop proved, probable and possible exploration and 
development resources focused mainly on crude oil development and the measuring of tight gas in the Neuquina basin. 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.

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, 2009, we were contractually committed to deliver 197 mbbl of crude oil in 
the future, generally under short term delivery contracts. According to our estimates as of December 31, 2009, crude oil commitments 
could be met with our own production.  

As of December 31, 2009, we were contractually committed to deliver 66,639 mmcm of natural gas in the future, of which 

approximately 27,021 mmcm will have to be delivered in the period from 2010 through 2012. According to our estimates as of 
December 31, 2009, our contractual delivery commitments for the next three years could be met with our own production and, if 
necessary, with purchases from third parties.  

However, since 2004 the Argentine government has established regulations for both the export and internal 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. 
Provisions totaling Ps. 139 million, Ps. 61 million and Ps. 596 million have been recorded in 2009, 2008 and 2007, respectively, in 
connection with our contractual commitments in the natural gas export market.  

Among the regulations adopted by the Argentine government, on June 14, 2007, the Argentine Secretariat of Energy passed 

Resolution No. 599/07, according to which we were compelled to enter into an agreement with the Argentine government regarding 
the supply of natural gas to the domestic market during the period 2007 through 2011 (the “Agreement 2007-2011”). It must be noted 
that YPF has not entered into any contractual commitment to supply natural gas to the domestic market. The purpose of the 
Agreement 2007-2011 is to guarantee the supply of natural gas to the domestic market at the demand levels registered in 2006, plus 
the growth in demand by residential and small commercial customers. See “—Regulatory Framework and Relationship with the 
Argentine Government—Market Regulation” and “Risk Factors—We are subject to direct and indirect export restrictions, which have 
affected our results of operations and caused us to declare force majeure under certain of our export contracts.” According to our 
estimates as of December 31, 2009, supply requirements under the Agreement 2007-2011 (which we were compelled to enter into and 
which was approved by a resolution that has been challenged by us) could be met with our own production and, if necessary, with 
purchases from third parties.  

We have appealed the validity of the aforementioned regulations and have invoked the occurrence of a force majeure event 

(government action) under our export natural gas purchase and sales agreements, although certain counterparties to such agreements 
have rejected our position. See “Item 8. Financial Information—Legal Proceedings—Argentina—Reserved, probable contingencies—
Alleged defaults under natural gas supply contracts”, “Item 8. Financial Information—Legal Proceedings—Argentina—Non-reserved, 
possible contingencies—Claims related to the gas market and others” and “Item 8. Financial Information—Legal Proceedings—
Argentina—Non-reserved, remote contingencies—Arbitration with AES Uruguaiana Empreendimentos S.A. (AESU), Companhia de 
Gás do Estado do Río Grande do Sul (Sulgás) and Transportadora de Gas del Mercosur S.A. (TGM).”

Natural gas supply contracts  
As mentioned above, the Argentine government has established regulations for both the export and internal natural gas markets 

which have affected Argentine producers’ ability to export natural gas under their contracts. The principal contracts of YPF among 
these are described briefly below.  

We are currently committed to supply a daily quantity of 125 mmcf/d to the Methanex plant in Cabo Negro, Punta Arenas, in 

Chile (under three 20-year agreements entered into in 1997, 1999 and 2005). Pursuant to instructions from the Argentine government, 
deliveries were interrupted from 2007.  

We have a 12-year contract (entered into in 1999 and subsequently modified) to supply 31 mmcf/d of natural gas to the 

Termoandes power plant located in Salta, Argentina. The natural gas comes from the Noroeste basin. This power plant provides power 
to a high voltage line running from Salta to Región II in Chile.  

We currently have several supply contracts with Chilean electricity producers (through the Gas Andes pipeline linking 
Mendoza, Argentina to Santiago, Chile, which has a transportation capacity of 353 mmcf/d (designed capacity with compression 
plants)), including a 15-year contract (signed in 1998) to provide 63 mmcf/d to the San Isidro Electricity Company (Endesa) in 
Quillota, Chile (all of this plant’s natural gas needs), a 15-year contract (signed in 1999) to supply 20% of the natural gas requirements 
of the electricity company, Colbun (approximately 11 mmcf/d), and a 15-year contract (signed in 2003) to supply 35 mmcf/d to Gas 
Valpo, a distributor of natural gas in Chile. We also have a 21-year contract (entered into in 1999) to deliver 93 mmcf/d of natural gas 
to a Chilean distribution company that distributes natural gas to residential and industrial clients through a natural gas pipeline (with a 
capacity of 318 mmcf/d) connecting Loma La Lata (Neuquén, Argentina) with Chile. Finally, in Chile we also have natural gas supply 
contracts with certain thermal power plants in northern Chile utilizing two natural gas pipelines (with a carrying capacity of 300 
mmcf/d each) connecting Salta, Argentina, to Northern Chile (Región II).  

In Brazil, we had entered into a 20-year supply contract (signed in 2000) to provide 99 mmcf/d of natural gas to the thermal 

power plant of AES Uruguaiana Empreendimentos S.A. (AESU) through a pipeline linking Aldea Brasilera, Argentina, to 
Uruguayana, Brazil (with a capacity of 560 mmcf/d). See “Item 8. Financial Information—Legal Proceedings—Argentina—Reserved, 
probable contingencies—Alleged defaults under natural gas supply contracts” and “Item 8. Financial Information—Legal 
Proceedings—Argentina—Non-reserved, remote contingencies—Arbitration with AES Uruguaiana Empreendimentos S.A. (AESU), 
Companhia de Gás do Estado do Río Grande do Sul (Sulgás) and Transportadora de Gas del Mercosur S.A. (TGM).” At the moment, 
YPF and Sulgás are in arbitration according to the Rules of Arbitration and Conciliation of the International Chamber of Commerce 
(ICC).  

Because of certain restrictions imposed by the Argentine government (see “—The Argentine natural gas market,” below), we 

could not meet our export commitments and were forced to declare force majeure under our natural gas export sales agreements. As a 
result of actions taken by the Argentine authorities, through measures described in greater detail under “—Regulatory Framework and 
Relationship with Argentine Government,” we have been forced to reduce the export volumes authorized to be provided under the 
relevant agreements and permits as shown in the chart below:

The Argentine natural gas market  

We estimate (based on preliminary reports of amounts delivered by transport companies) that natural gas consumption in 
Argentina totaled approximately 1,547 bcf in 2009. We estimate that the number of users connected to distribution systems throughout 
Argentina amounted to approximately 7.4 million as of December 31, 2009. The average annual domestic consumption of natural gas 
has grown significantly over recent years, driven by the forces of economic growth and domestic price; although we do not believe 
that the natural gas market will continue to grow at the same rate as it has recently done.

In 2009, we sold approximately 32% of our natural gas to local residential distribution companies, approximately 64% to 

industrial users (including Compañía Mega S.A. (Mega) and Profertil S.A. (Profertil)) and power plants, and approximately 4% in 
exports to foreign markets (principally Chile). Approximately 75% of our natural gas sales were produced in the Neuquina basin. 
During 2009, our domestic natural gas sales volumes were 9.6% less than those in 2008, mainly due to the greater offer of hydraulic-
generated energy and the lower consumption of residential markets because of the smooth winter temperatures.  

Demand for natural gas has been driven by domestic constraints on natural gas prices that commenced in 2002 following the 
currency devaluation, which created very low prices for natural gas as compared to alternative fuels. However, as explained above, 
domestic sales decreased in 2009.  

In January 2004, Decree No. 181/04 authorized the Argentine Secretariat of Energy to negotiate with 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. Subsequently, the Argentine government has taken a number of additional steps aimed at 
satisfying domestic natural gas demand, including pricing regulations, export controls and higher export taxes and domestic market 
injection requirements. See “Regulatory Framework and Relationship with 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 injection orders pursuant to Resolutions No. 659 and No. 752 (which allow Argentine authorities to 
require exporters to increase supply of natural gas into 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.  

These restrictions were imposed on all Argentine exporting producers, affecting natural gas exports from every producing basin. 

See “—Delivery commitments—Natural gas supply contracts”. Exporting producers, such as us, have no choice but to comply 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. The above-mentioned Resolutions provide penalties for non-compliance. Rule SSC 
No. 27/2004 issued by the Undersecretary of Fuels (“Rule 27”), for example, punishes the violation of any order issued thereunder by 
suspending or revoking the production concession. Resolutions No. 659 and No. 752 also provide that producers not complying with 
injection orders will have their concessions and export permits suspended or revoked and state that pipeline operators are prohibited 
from shipping any natural gas injected by a non-complying exporting producer.  

The Argentine government began restricting 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. The 
regulations pursuant to which the Argentine government has restricted natural gas export volumes in most cases do not have an 
express expiration date. Likewise, we have not received any documentation indicating that the Argentine government will suspend or 
withdraw these actions. Accordingly, we are unable to predict how long these measures will be in place, or whether such measures or 
any further measures adopted will affect additional volumes of natural gas.  

In June 2007, we were compelled pursuant to Resolution No. 599/07 of the Argentine Secretariat of Energy to enter into the 

Agreement 2007-2011, with the Argentine government regarding the supply of natural gas to the domestic market. See “—Delivery 
commitments.”  

In September 2008, the Argentine Secretariat of Energy, through Resolution No. 1070, increased the price of natural gas for 

certain segments, including the residential, NGV (Natural Gas Vehicle) and power plant segments, with part or all of the proceeds of 
the increases to be paid into a fiduciary fund to subsidize the price of LPG consumed by lower income customers. Additionally, 
Resolution No. 1417 (December 2008) increased the price of natural gas for the residential segment with highest energy consumption 
rates, as defined under such Resolution. Pursuant to the Resolution, such increase in prices is effective with respect to consumption 
since November 2008.  

Executive Decree No. 2067/2008 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 internal demand. The fiduciary fund will be funded through the 
following mechanisms: (i) various tariff charges to be paid by users of regular transport (which shall be invoiced by the 
transporters/distributors on firm 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. The application 
of the resolution was temporarily suspended in the period from June to September 2009, with respect to certain users of the residential 
segment.  

35 

 
  
On July 17, 2009, the Ministry of Federal Planning, Public Investment and Services and certain natural gas producers (including 
YPF) signed an agreement which set 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 in respect of volumes sold to the residential segment from 
August 2009 onwards. The previously mentioned amounts will be adjusted monthly so that the resulting amounts represent 50% of the 
amount collected by the fiduciary fund to finance natural gas imports. See “—Regulatory Framework and Relationship with the 
Argentine Government—Market Regulation—Natural gas.”  

Argentine natural gas supplies  

Most of our proved natural gas reserves in Argentina are situated in the Neuquina basin (approximately 77% as of December 31, 

2009), 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. The Framework Agreement between the Bolivian and the Argentine governments 
(executed on June 29, 2006) provides for natural gas imports from Bolivia to Argentina to be managed by ENARSA. The Framework 
Agreement establishes a 20-year delivery plan of between 7.7 and 27.7 mmcm/d of Bolivian gas to Argentina. The delivery of 
volumes exceeding 7.7 mmcm/d is subject to the construction of the North East Pipeline, with an expected capacity of 20 mmcm/d. 
The agreed upon price was approximately U.S.$6.16/mmBtu in December 2009, and is periodically adjusted according to a formula 
based upon a basket of fuels. In the past, the increased cost of the natural gas purchased pursuant to the Framework Agreement has 
been absorbed by ENARSA and financed by the Argentine government with the collection of export duties on natural gas and some 
other charges added to domestic natural gas prices. In the context of the Framework Agreement, on April 25, 2007, we accepted the 
offer made by ENARSA for the sale to us of natural gas obtained by ENARSA from the Republic of Bolivia through December 31, 
2009. The principal terms and conditions of our agreement with ENARSA, effective through December 31, 2009, were as follows: 
(i) maximum contracted quantity of up to 4.4 mmcm/d; (ii) annual take-or-pay quantity equal to 80% of the maximum contracted 
quantity; (iii) price of U.S.$1.9/mmBtu for the natural gas (subject to monthly adjustments), plus U.S.$0.237/mmBtu for the liquid 
components contained therein; (iv) price adjustments may be made at any time in relation to changes in the Argentine government’s 
compensation to ENARSA; and (v) limited allowed curtailments or interruptions of supply due to operative conditions and scheduled 
maintenance. In May 2010, we accepted the offer made by ENARSA for the sale to us of a minimum amount of 2.5 mmcm/d of 
natural gas obtained by ENARSA from the Republic of Bolivia through May 1, 2011.  

In 2008, YPF, jointly with ENARSA, contracted a regasification ship to operate in the Bahía Blanca Port using a ship-to-ship 

process for the conversion of liquefied natural gas (LNG) into its gaseous form. Once converted, the natural gas is injected into a 
newly built pipeline linking to the national network. As a result, an additional supply of up to 8 mmcm/d of natural gas to the 
Argentine market was provided during the peak demand period.  

Following the 2008 regasification season, between May 1 and October 31, 2009, YPF has continued providing regasification 

services to ENARSA. YPF has executed a Charter Party Agreement to provide and operate a regasification vessel, which is moored at 
the Bahía Blanca Port facilities. Using the vessel for the conversion of liquefied natural gas (LNG) into its gaseous state (which allows 
for the supply of up to 8 additional mmcm/d of natural gas), a volume of approximately 780 mmcm of natural gas has been injected 
into the pipeline linking to the national network, most of which was supplied during the peak demand period. The contractual 
regasification period (originally ending at the end of October 2009) has been extended pursuant to an Extension Agreement entered 
into by YPF and ENARSA (at the request of ENARSA) to secure the supply of natural gas to the domestic market over the time 
period starting on November 1, 2009 and ending on April 30, 2010.  

In accordance with the Extension Agreement, the 2010 regasification season will start on May 1 and will end on September 30 

(unless extended for 30 days pursuant to the Charter Party Agreement and Extension Agreement). The current success of the Bahía 
Blanca project in addition to the continued growth of the domestic demand encourages YPF and ENARSA to further analyze new 
alternatives to consolidate the position of LNG in the Argentina energy matrix.  

Natural gas transportation and storage capacity  

Decree No. 180/2004 created two trust funds to help finance an expansion of the North Pipeline operated by Transportadora Gas 
del Norte S.A. (TGN), whose capacity increased by 1.8 mmcm/d (63.6 mmcf/d) in 2005, and an expansion of the San Martín Pipeline 
operated by Transportadora Gas del Sur S.A. (TGS), whose capacity increased by 2.9 mmcm/d (102.4 mmcf/d) in 2005. Both 
expansions are currently operating. In 2008, there was an additional expansion of approximately 67 mmcf/d in the pipelines operated 
by TGS, and additional works were completed in 2009. In mid-2010 (coinciding with winter), the expansion of the San Martín 
pipeline (located in the Strait of Magellan and connected to compression plants in the mainland) is expected to finalize with an 
increase in capacity of 5 mmcm/d (176.6 mmcf/d).  

36 

 
Natural gas is delivered by us through our own gathering systems to the trunk lines from each of the major basins. The firm 
capacity of the natural gas transportation pipelines in Argentina is mainly used by the distribution companies under long-term firm 
transportation contracts. All of the available capacity of the transportation pipelines is taken 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 near consuming markets as underground natural gas storage facilities, 

with the objective of storing natural gas during periods of low demand and selling the natural gas stored during periods of high 
demand. Our principal gas storage facility, “Diadema,” is located in the Patagonia region, near Comodoro Rivadavia City. The 
injection of natural gas into the reservoir started in January 2001.  

Other investments and activities  
Natural gas liquids  

We participated in the development of Mega to increase its ability to separate liquid petroleum products from natural gas. Mega 

allowed YPF, through the fractionation of gas liquids, to increase production at the Loma La Lata gas field by approximately 5.0 
mmcm/d in 2001.  

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 Loma La Lata, in the province of Neuquén.  
•   A natural gas liquids fractionation plant, which produces ethane, propane, butane and natural gasoline. This plant is located 

in the city of Bahía Blanca in the province of Buenos Aires.  

•   A pipeline that links both plants and that transports natural gas liquids.  
•   Transportation, storage and port facilities in the proximity of the fractionation plant.  

Mega commenced operations at the beginning of 2001. Mega’s maximum annual production capacity is 1.35 million tons of 

natural gasoline, LPG and ethane. YPF is Mega’s main supplier of natural gas. The production of the fractionation plant is used 
mainly in the petrochemical operations of Petroquímico Bahía Blanca (“PBB”) and is also exported by tanker to Petrobras’ facilities in 
Brazil.  

Mega’s LPG production is acquired by Petrobras pursuant to the sale contract executed between Petrobras and Mega in 1999 

(the “LPG Contract”), which defines the LPG sale price in relation to the Mont Belvieu quotation. In 2005, Petrobras requested Mega 
to review the price of the LPG Contract since it considered that the Mont Belvieu quotation had departed from other quotations and 
become more expensive and, therefore, alleged that such variation in the quotations was a case of hardship. Mega did not agree with 
that request and, pursuant to the terms of the LPG Contract, the parties appointed an expert, Purvin & Gertz, whose final report was 
issued in 2006 concluding that it was not a case of hardship. In 2008, Petrobras brought an arbitration claim before the International 
Court of Arbitration of the International Chamber of Commerce against Mega regarding this matter, requesting compensation of 
U.S.$91 million and the amendment of the LPG Contract with respect to future transactions in a way that would reduce the Mont 
Belvieu quotation and transform long-term contract into a spot contract. On April 21, 2010, we were notified that the Arbitral Tribunal 
has decided to dismiss all claims brought by Petrobras. Furthermore, the Arbitral Tribunal has ruled that Petrobras shall pay costs 
incurred by Mega in the arbitration proceeding.  

Electricity market – generation  

We participate in three power stations with an aggregate installed capacity of 1,622 megawatts (“MW”):  

•   a 45% interest in Central Térmica Tucumán (410 MW combined cycle) through Pluspetrol Energy Sociedad Anónima 

(“Pluspetrol Energy”);  

•   a 45% interest in Central Térmica San Miguel de Tucumán (370 MW combined cycle) through Pluspetrol Energy; and  
•   a 40% interest in Central Dock Sud (775 MW combined cycle and 67 MW gas turbines), directly and through 

Inversora Dock Sud S.A.  

In 2009, these plants collectively generated approximately 7,160 GWh in the aggregate.  

Additionally, we own assets that are part of Filo Morado, which has an installed capacity of 63 MW. However the relevant 

facilities have not been in operation since November 2008.  

37 

 
  
  
We also own and operate power plants supplied with natural gas produced by us, which produce power for use by us in other 

business units:  

•   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  
•   the power plant located at the Plaza Huincul refinery (40 MW).  

Natural gas distribution  

We currently hold through our subsidiary YPF Inversora Energética S.A. (“YPF Inversora Energética”) a 45.33% stake in Gas 

Argentino S.A. (“GASA”), which in turn holds a 70% stake in Metrogas S.A. (“Metrogas”), which is a natural gas distributor in 
southern Buenos Aires and one of the main distributors in Argentina. During 2009, Metrogas distributed approximately 23.6 mmcm of 
natural gas per day to 2 million customers in comparison with approximately 22.9 mmcm of natural gas per day distributed to 
2 million customers in 2008.  

The economic crisis that affected the country at the end of 2001 and beginning of 2002 caused a severe deterioration of the 
financial and operational situation of GASA. Thus the decision was made on March 25, 2002 to suspend payment of principal and 
interest on its entire financial debt. From then on, Metrogas’ management has focused on an efficient and rational use of its cash flow 
in order to be able to comply with all of the legal requirements agreed with the Argentine government with respect to its services. 
After negotiating a restructuring of the outstanding debt with its creditors, GASA reached and executed on December 7, 2005 an 
agreement (the Master Restructuring Agreement, or “MRA”) with its creditors, by which they would exchange debt for equity in 
GASA and/or Metrogas. After this exchange was completed, YPF Inversora Energética would hold a 31.7% stake in GASA. The 
MRA was presented to the Argentine National Antitrust Protection Board (Comisión Nacional de Defensa de la Competencia or 
“CNDC”) and the National Gas Regulatory Authority (Ente Nacional Regulador del Gas or “ENARGAS”) and was subject to their 
approval as a condition precedent to the closing of the MRA. The MRA included a creditors’ option to terminate the agreement if the 
closing of the debt restructuring had not occurred by December 7, 2006. The MRA obtained ENARGAS’ approval but the CNDC’s 
approval was pending. On May 15, 2008, certain holders of the bonds communicated to YPF Inversora Energética that they were 
terminating the MRA. After the termination of the MRA, three different entities claiming to be holders of GASA bonds commenced 
four different judicial proceedings against GASA aiming to collect a total of U.S.$46 million, including interest and fees, and one of 
them, Coolbrand LLC, started a separate proceeding (“Coolbrand c/Gasa s/acción subrogatoria”). On May 11, 2009, GASA was 
notified of a bankruptcy petition brought by Continental Energy Investment LLC. On May 19, 2009, GASA filed a voluntary 
reorganization petition (“concurso preventivo”), which was approved on June 8, 2009. On June 12, 2009, an official receiver was 
nominated. The period to verify credits ended on October 7, 2009, and on October 22, 2009, GASA filed its comments to such 
presentations. On November 19, 2009, the official receiver issued its report advising that the credits should be admitted. On 
February 10, 2010 the judge declared all the credits verified but for one presented by one of GASA’s advisors. GASA now has an 
exclusivity period to negotiate with the verified creditors. On March 12, 2010, GASA filed motions for review (“incidentes de 
revisión”) of credits verified by Coolbrand LLC, Amanda Venture, Latam Energy and Continental Energy. The filing of these motions 
does not suspend the voluntary reorganization petition. The judge has established August 10, 2010 as the date to formally present 
GASA’s proposal to the creditors.  

In 2006, Metrogas reached an agreement with its main creditors in order to restructure its financial debt and align its future 
financial commitments to the expected generation of funds. The main objective of the restructuring process was to modify certain 
terms and conditions included in its outstanding loans and negotiable agreements by adjusting interest rates and the amortization 
period so as to align them with the expected cash flow required for repayment of the indebtedness. Accordingly, on April 20, 2006, 
Metrogas entered into an out-of-court preventive agreement with creditors representing approximately 95% of its unsecured 
indebtedness, which became effective in May 2006. In October 2008, Metrogas executed an interim agreement (Acuerdo Transitorio) 
with the Unit for the Renegotiation and Analysis of Public Service Contracts (Unidad de Renegociación y Análisis de Contratos de 
Servicios Públicos, or “UNIREN”), including a limited tariff increase that is intended to fund certain projects that Metrogas is required 
to undertake. The government has approved this agreement and it has been published in the Official Gazette on April 14, 2009 but it 
has not been implemented since the new tariff chart has not yet been issued. The negotiation of the general tariff of Metrogas (Acta 
Acuerdo de Renegociación Contractual Integral) with the UNIREN remains pending.  

Metrogas’ financial condition continued to deteriorate in 2009. On June 17, 2010, the Board of Directors of Metrogas, following 
the advice of Metrogas’ external legal advisors and considering Metrogas’ inability to fullfil certain payment obligations, decided that 
Metrogas should file a voluntary reorganization petition (“concurso preventivo”), which was filed on such date.  

As of December 31, 2009, YPF had an allowance for the total value of its investment in YPF Inversora Energética.

Refining and Marketing  

During 2009, our Refining and Marketing activities included crude oil refining and transportation, and the marketing and 

transportation of refined fuels, lubricants, LPG, compressed natural gas and other refined petroleum products in the domestic 
wholesale and retail markets and certain export markets.  

The Refining and Marketing segment is organized into the following divisions:  

•   Refining and Logistic Division;  

•   Refining Division  
•   Logistic Division  
•   Trading Division  

•   Domestic Marketing Division; and  
•   LPG General Division.  

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 (together referred as the “refineries”).  

Our three wholly-owned refineries have an aggregate refining capacity of approximately 319,500 barrels per calendar day. The 

refineries are strategically located along our crude oil pipeline and product pipeline distribution systems. In 2009, our crude oil 
production, substantially all of which was destined to our refineries, represented approximately 78% of the total crude oil processed by 
our refineries. Through our stake in Refinor, we also own a 50% interest in a 26,100 barrel-per-calendar-day refinery located in the 
province of Salta, known as Campo Durán.  

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

years ended December 31, 2009, 2008 and 2007:

In 2009, overall volumes of crude oil/feedstock processed decreased by 5.5% compared with 2008 due mainly to scheduled 
maintenance overhauls at our La Plata refinery, as well as our production optimization efforts in response to market conditions and the 
decrease in sales volumes in foreign markets (which decreased 37% compared with 2008). In 2009, our refinery capacity utilization 
was 94.9%, compared to over 100% in 2008. This was principally due to maintenance overhaul performed at our largest crude 
distillation unit, Topping C (located in our La Plata refinery). In addition, union conflicts in the upstream business and in the port 
crude oil storage facilities resulted in crude shortages. In 2008, overall volumes of crude oil/feedstock processed decreased by 3.8% 
compared with 2007 due to major overhauls at our Luján de Cuyo and La Plata refineries, and in response to the decrease in sales 
volumes in foreign markets (which decreased 8.8% compared with 2007).  

The La Plata refinery is the largest refinery in Argentina, with a nominal capacity of 189,000 barrels of crude oil per calendar 

day. The refinery includes three distillation units, two vacuum distillation units, two catalytic cracking units, two coking units, a coker 
naphtha hydrotreater unit, a platforming unit, a gasoline hydrotreater, a diesel fuel hydrofinishing unit, an isomerization unit, an FCC 
(Fluid Cracking Catalysts) naphtha splitter and desulfuration unit, and a lubricants complex. The refinery is located at the port in the 
city of La Plata, in the province of Buenos Aires, approximately 60 kilometers from the City of Buenos Aires. In 2009, the refinery 
processed approximately 172,400 barrels of crude oil per calendar day. The capacity utilization rate at the La Plata refinery for 2009 
was 91.2%, 9.2% lower than in 2008. In 2008, the refinery processed approximately 192,600 barrels of crude oil per calendar day. The 
capacity utilization rate at the La Plata refinery for 2008 was 0.1% higher than in 2007. The crude oil processed at the La Plata 
refinery comes mainly from our own production in the Neuquina and Golfo San Jorge basins. Crude oil supplies for the La Plata 
refinery are transported from the Neuquina basin by pipeline and from the Golfo San Jorge basin by vessel, in each case to Puerto 
Rosales, and then by pipeline from Puerto Rosales to the refinery.  

In October 2009, we commenced developing a detailed engineering project for a new Gasoil Hydrotreater Unit (HTG “B”), 

seeking to comply with Resolution 478/09, which requires companies to produce diesel fuel with a maximum level of sulfur of 500 
parts per million, to be sold in large cities.  

The Luján de Cuyo refinery has a nominal capacity of 105,500 barrels per calendar day, the third largest capacity among 
Argentine refineries. The refinery includes two distillation units, a vacuum distillation unit, two coking units, one catalytic cracking 
unit, a platforming unit, a Methyl TerButil Eter (“MTBE”) unit, an isomerization unit, an alkylation unit, a naphtha splitter, and 
hydrocracking and hydrotreating units. In 2009, the refinery processed approximately 107,500 barrels of crude oil per calendar day. In 
2009, the capacity utilization rate was 3.3% higher than in 2008, reaching a rate of 101.9%. In 2008, the capacity utilization rate was 
2.4% lower than in 2007, due to maintenance overhauls. Because of its location in the western province of Mendoza and its proximity 
to significant distribution terminals owned by us, the Luján de Cuyo refinery has become the primary facility responsible for providing 
the central 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 83.0% of the crude oil processed 
at the Luján de Cuyo refinery in 2009 was produced by us. Most of the crude oil purchased from third parties comes from oil fields in 
Neuquén or in Mendoza.  

In 2008, we begun constructing a new furnace in Topping III (in the Luján de Cuyo refinery), that will replace the three furnaces 

that are actually in operation. This will also allow us to increase the nominal capacity of the unit by 2,500 barrels per calendar day. 
The start up of the new furnace is planned for the second semester of 2010.  

In order to comply with government regulations on sulfur specifications for fuels, which will become effective in the middle of 

2012, the Luján de Cuyo refinery is developing two projects: a naphtha Hydrotreater Unit (HTN II) and a gasoil Hydrotreater Unit 
(HDS III). The developing basic engineering stage with respect to the first project has been completed, while the second project is 
currently at that stage.  

The Plaza Huincul refinery, located near the town of Plaza Huincul in the province of Neuquén, has an installed capacity of 

25,000 barrels per calendar day. In 2009, the refinery processed approximately 23,400 barrels of crude oil per calendar day. In 2009, 
the capacity utilization rate was 15.4% lower than in 2008, reaching a rate of 93.6%. In 2008, the refinery processed approximately 
27,600 barrels of crude oil per calendar day. In 2008, the capacity utilization rate was 1.6% higher than in 2007. The only products 
currently produced commercially at the refinery are gasoline, diesel fuel 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 La Plata refinery for further processing. The Plaza Huincul refinery receives its crude 
supplies from the Neuquina basin by pipeline. Crude oil processed at the Plaza Huincul refinery is mostly produced by us. In 2009, 
26% of the refinery’s crude supplies were purchased from third parties.

At the end of 2009, we completed the construction of tanks and facilities for the reception and blending of biodiesel in order to 

facilitate compliance in the future with new specifications for diesel fuel as established pursuant to Law 26,093. See “—Domestic 
Marketing Division.” During 1997 and 1998, each of our refineries were certified under ISO (International Organization for 
Standardization) 9001 (quality performance) and ISO 14001 (environmental performance). The Luján de Cuyo and Plaza Huincul 
refineries were also certified under OHSAS 18001 (security performance) in 1999 and 2009, respectively. Between 2007 and 2009, 
our refineries were recertified under ISO 9001:2000, ISO 14001:2004 and OHSAS 18001:2007.  

Capital expenditures in 2009 for environmental projects at the three refineries amounted to U.S.$92.7 million.  

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 kilometers 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:

(1) 

Includes two parallel pipelines of 513 kilometers each from Allen to Puerto Rosales, with a combined daily throughput of 
232,000 barrels.  

(2)  We hold a 36% interest in Oleoducto Transandino Argentina S.A., which operated the Argentine portion of the pipeline, and a 

18% interest in Oleoducto Transandino Chile S.A., which operated the Chilean portion of the pipeline.  

(3)  This pipeline ceased operating on December 29, 2005.  

We own two crude oil pipelines in Argentina. One connects Puesto Hernández to the Luján de Cuyo refinery (528 kilometers), 

and the other connects Puerto Rosales to the La Plata refinery (585 kilometers ) and extends to Shell’s refinery in Dock Sud at the 
Buenos Aires port (another 52 kilometers). 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 cubic meters, and two tanks in the city of Berisso, in the province of Buenos Aires, with 
60,000 cubic meters of capacity. We own 37% of Oleoductos del Valle S.A., operator of an 888-kilometer pipeline network, its main 
pipeline being a double 513 kilometer pipeline that connects the Neuquina basin and Puerto Rosales.  

As of December 31, 2009, we held, through Oleoducto Transandino Argentina S.A. and Oleoducto Transandino Chile S.A., an 
interest in the 428-kilometer 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 assets related to this pipeline were 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 cubic meters, and Caleta Olivia (province of Santa Cruz), which has a capacity 
of 246,000 cubic meters. 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 cubic meters, and of the crude oil pipeline that connects Brandsen (60,000 cubic meters of storage 
capacity) to the ESSO 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 kilometers. We also own 16 plants for the storage and distribution of refined products with an approximate aggregate capacity 
of 1,023,122 cubic meters. Three of these plants are annexed to the refineries of Luján de Cuyo, La Plata and Plaza Huincul. Ten of 
these plants have maritime or river connections. We operate 53 airplane refueling facilities (40 of them are wholly-owned) with a 
capacity of 24,000 cubic meters, own 27 trucks, 112 suppliers and 16 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 shipped mainly by truck, ship or river barge.

In January 2010, we completed the construction of tanks and facilities for the reception and blending of ethanol in the storage 
plants of Luján de Cuyo, Montecristo and San Lorenzo, in order to facilitate compliance with the new specifications for gasoline set 
forth by Law 26,093. YPF is currently producing this blending in the storage plants of Luján de Cuyo, Montecristo and San Lorenzo. 
Similar construction work in the rest of our plants is expected to be finished during the years 2010 and 2011.  

Capital expenditures in 2009 for safety and environmental projects at the logistic division amounted to U.S.$10.4 million.  

Trading division  

Our Trading Division sells refined products and crude oil to international customers and oil to domestic oil companies. Exports 

include crude oil, unleaded gasoline, diesel fuel, fuel oil, LPG, light naphtha and virgin naphtha. This Division’s export sales are made 
principally to Brazil and the United States. Sales to international customers for the years 2009 and 2008 totaled Ps.2,878 million and 
Ps. 5,916 million, respectively, 79% and 84% of which, respectively, represented sales of refined products and 21% and 11% of 
which, respectively, represented sales of marine fuels. On a volume basis, in 2009 and 2008 sales to international customers consisted 
of 11.2 mmbbl and 17.8 mmbbl of refined products, respectively, and 2.49 mmbbl and 1.93 mmbbl of marine fuels, respectively. In 
addition, we sold 2.02 mmbbl of crude oil to international customers in 2008 (compared to almost no sales to international customers 
in 2009). Domestic sales of crude oil totaled Ps.485 million and Ps.377 million and 3.1 mmbbl and 2.7 mmbbl in 2009 and 2008, 
respectively. Domestic sales of marine fuels totaled Ps.380 million and Ps.379 million and 1.4 and 1.5 mmbbl in 2009 and 2008, 
respectively.  

Domestic marketing division  

Through our Marketing Division, we market gasoline, diesel fuel, LPG and other petroleum products to retail and wholesale 

customers.  

In 2009, retail, wholesale, lubricants and specialties and aviation sales reached Ps.20,479 million, representing 74.3% of the 

Refining and Marketing segment’s consolidated revenue, with Ps.12,693 million generated by retail customers.  

As of December 31, 2009, the Marketing Division’s sales network in Argentina included 1,632 retail service stations (compared 

to 1,642 at December 31, 2008), of which 92 are directly owned by us, and the remaining 1,540 are affiliated service stations. 
Operadora de Estaciones de Servicio S.A. (“OPESSA”), our wholly-owned subsidiary, operates 168 of our retail service stations, 79 
of which are directly owned by us, 25 of which are leased to ACA (Automóvil Club Argentino), and 64 of which are leased to 
independent owners. Additionally, we have a 50% interest in Refinor, which operates 71 retail service stations. We will continue our 
efforts to improve our service stations network, through the incorporation of stations in new locations and the elimination of existing 
non-strategic stations, and dealer-operated stations which do not comply with the level of operational efficiency that we require.  

During 2009 we adopted a new design for stations integrating our service stations network. This new image will be deployed 

during 2010-2011.  

We estimate that, as of December 31, 2009, our points of sale accounted for 30.9% of the Argentine market. In Argentina, Shell, 

Petrobras and ESSO are our main competitors and we estimate that, as of December 31, 2009, they owned approximately 15.2%, 
12.8% and 10.5%, respectively, of the points of sale in Argentina, according to the latest information available to us. During 2009, we 
believe all oil companies maintained the number of their points of sales.  

During 2009, we slightly increased our market share in the diesel fuel and gasoline markets from 54.9% to 57.4%, according to 

our analysis of data provided by the Argentine Secretariat of Energy.  

The “Red XXI” marketing program, launched in October 1997, which has significantly improved operational efficiency and 
provides us with immediate performance data from each station, is aimed at connecting most of our service stations network. As of 
December 31, 2009, 1,468 stations were linked to the Red XXI system.  

In 2007, we launched the Escuela Comercial YPF (YPF Business School), which focuses on performance, employability, 
operational excellence and customer satisfaction. The YPF Business School is aligned with our business strategy to promote a sense of 
belonging and common vision shared by all the members of our business chain. In 2008, we worked to give the YPF Business School 
greater regional and thematic focus. During 2008, we complemented its global approach with the development of more specific 
content, focusing on particular areas of our business. In 2008, the YPF Business School carried out 1,011 courses, visits to service 
stations and other business development-related activities, involving 1,832 of our employees or business partners (owned and branded 
service stations and distributors). In 2009, we focused on improving the quality of our customer service. This was done through our 
service and sales courses, specifically designed for our distributors and service stations sales staff. A total of 1,942 students took part 
in 454 courses, out of which 408 focused on service and sales. Between 2007 and 2008, 668 students graduated. During 2009, around 
500 students were added to that number.  

42 

 
  
We began an ISO 9001 certification process involving our gas station network in 1998. Currently, we allow each gas station 

operator to certify its management system. YPF-owned service stations have been certified under ISO 9001 and 14000 standards for 
the past ten years, and a small number of such service stations have been certified under OHSAS 18001 and ISO 22000 in the past 
three years.  

YPF-owned service stations have replaced ISO standards with a self-certification quality standards model, we believe may be 

adopted by our network of affiliated service stations operators. This model was under development during 2008 and 2009, and is 
expected to begin to be phased in at all YPF-owned service stations in 2010.  

Our sales to the agricultural sector are principally conducted through a network of 125 distribution bases operated by 111 
distributors (eight of which are owned by us). Sales to transportation, industrial, utility, and mining sectors are made primarily through 
our direct sales efforts. The main products sold in the domestic wholesale market include diesel fuel and fuel oil.  

Sales to the aviation sector are made directly by us. The products sold in this market are jet fuel and aviation gasoline.  

Our lubricants and specialties unit markets a wide variety of products that includes lubricants, greases, asphalt, paraffin, base 

lubricant, decanted oil, carbon dioxide and coke. This unit is responsible for the production, distribution and commercialization of the 
products in the domestic and exports markets. These operations are ISO 9001:2000 and Tierra 16949 certified. The lubricants 
production facilities are also ISO 14001 certified.  

During 2009, our lubricants and specialties sales to domestic markets increased by 3.2% from Ps.1,586 million in 2008 to 

Ps.1,636 million in 2009. We export lubricants to 6 countries. Sales to export markets decreased by 34.6% from Ps.327 million in 
2008 to Ps.214 million in 2009. During 2009, total lubricants sales decreased by 28%, total asphalt sales increased by 30% and total 
derivatives sales decreased by 20%.  

In a market characterized by increasing costs, the strategy of differentiation followed by our lubricants and specialties unit 
allowed it to maintain its position of leadership in the Argentine market. Our market share as of December 31, 2009 was 36.4%. Lead 
domestic automotive manufacturers Ford, Volkswagen, Scania, Seat, Porsche, Subaru, Alfa Romeo and General Motors, exclusively 
use and recommend YPF-branded lubricant products.  

Since January 2010, every oil company in Argentina is obligated under Argentine law (Law 26,093) to blend all fuels with 5% 

of biofuels.  

Continuing with our commitment to the environment and the development of alternative fuels, the Bioenergy Program 2007-
2010 completed its second year of activity. This nationwide research and development program is being developed together with a 
university and other official entities with the objective of developing alternative crops to be used in the production of biofuels, thereby 
also promoting development in regional economies in Argentina. Our main objectives in the biofuel area are to secure our biofuel 
needs for the domestic market and to create associations for the production and marketing of biofuels in light of Argentina’s potential 
as a biofuels exporter to the European Union and other international markets.  

LPG general division  

Production  
We are one of the largest LPG producers in Argentina, with a yearly production of 534,643 tons in 2009 (not including 

production of LPG destined for petrochemical usage).  

We also have a 50% interest in Refinor, a jointly-controlled company, which produced 323,945 tons of LPG in 2009.  

43 

 
  
The LPG division obtains LPG from natural gas processing plants and from its refineries and petrochemical plant. It also 

purchases LPG from third parties as detailed in the following table:

volume purchased from January to August amounted to 18,671 tons.  

(2)  This production does not include LPG used as petrochemical feedstock (olefins derivatives, polybutenes and maleic).  
(3)  Purchased from Refinor.  

LPG marketing  
We sell LPG to the foreign market, the domestic wholesale market and to distributors that supply the domestic retail market. 
The LPG general division does not directly supply the retail market and such market is supplied by Repsol YPF Gas S.A., which is not 
a YPF company.  

Our LPG sales for the years 2009 and 2008 can be broken down by market as follows:

Total sales of LPG (excluding LPG used as petrochemical feedstock) to all markets (domestic and foreign markets combined) 

were Ps.699 million and Ps.967 million in 2009 and 2008, respectively.  

Chemicals  

In 2009 and 2008, our revenues from chemical sales were Ps.3,037 million and Ps.3,923 million, respectively, and our operating 

income of the Chemicals segment was Ps.559 million and Ps.1,178 million, respectively.  

In 2009, operating income was 52% lower than in 2008, mainly due to the impact of the international economic crisis which 

resulted in a significant decrease in margins and volumes during the first two quarters of the year.  

Petrochemicals are produced at our petrochemical complexes in Ensenada and Plaza Huincul, as well as in Bahía Blanca, where 

Profertil’s petrochemical complex is located.

Our petrochemical production operations in Ensenada are closely integrated with our refining activities (La Plata refinery). This 

close integration allows for a flexible supply of feedstock, the efficient use of byproducts (such as hydrogen) and the supply of 
aromatics to increase gasoline octane levels.

(1)  Corresponds to our 50% interest in Profertil.  

Natural gas, the raw material for methanol, is supplied by our upstream unit. The use of natural gas as a raw material allows us 

to monetize reserves, demonstrating the integration between the petrochemical and the upstream units.  

We also use high carbon dioxide-content natural gas in our methanol production, allowing us to keep our methanol plant 

working at 50% of its production capacity during the winter period.  

The raw materials for petrochemical production in Ensenada, including virgin naphtha, propane, butane and kerosene, are 

supplied mainly by the La Plata refinery.  

In 2009 and 2008, 27.0% and 26.8%, respectively, of our petrochemicals sales (including propylene) were made in the export 

market. Petrochemicals exports are destined to Mercosur countries, Latin America, Europe, and the United States.  

We also participate in the fertilizer business directly and through Profertil, our 50%-owned subsidiary.  

Profertil is jointly controlled by us and Agrium (a worldwide leader in fertilizers), that produces urea and ammonia and started 

operations in 2001.  

Our Ensenada petrochemical plant was certified under ISO 9001 in 1996 and recertified in June 2009 (version 2008). The La 
Plata petrochemical plant was certified under ISO 14001 in 2001 and recertified (version 2004) in October 2007. The plant was also 
certified under OHSAS 18001 in 2005 and recertified in June 2009 (version 2007). For the periods 2008 and 2009, the plant also 
certified the inventory of CO2 emissions under ISO 14064:1. The laboratory of our Ensenada petrochemical plant was certified under 
ISO 17025 (Version 2005) in 2005 and recertified in 2008.  

Our Methanol plant was certified under ISO 9001 (version 2000) in December 2001 (and recertified in June 2009 (version 

2008)), under ISO 14001 (Version 2000) in October 2007 and OHSAS 18001 in December 2008.

During 2009, an investment project was approved to increase our aromatics capacity by 50%. Total investment is estimated to 

be Ps. 1,350 million, which would include the installation of a Continuous Catalytic Reforming unit (CCR) at the Ensenada Industrial 
Complex. Start up is expected by the second half of 2012. New production is expected to meet the growing demand of high octane 
gasoline in the local market, while at the same time the CCR is expected to provide hydrogen to the new Hydrotreater Unit in our La 
Plata Refinery.  

Research and Development  

We have a research and development facility in La Plata, Argentina. YPF pursues an active policy of cooperation with 
technology centers and universities in the public and private sector, nationally and internationally. Our budget for such cooperation 
arrangements was approximately U.S.$1 million in 2009. Two important research and development (R&D) projects were partly 
subsidized by Fontar (the Argentine Technology Fund).  

Uncertainty about what will be the dominant technologies in the future, prospective R&D results, business cycles and cost 
reduction stresses at low points in the cycle have led YPF to develop a Strategic Technology Plan as part of its business strategy. The 
plan covers all parts of the company’s business: exploration and production of hydrocarbons, the natural gas value chain, oil refinery 
and its derivatives and petrochemicals, in addition to avenues for future diversification in energy use and production including the use 
of biofuels and electric transport.  

The R&D projects and activities apply to the entire value chain of the business, including exploration of new deposits of crude 

or gas, extraction and conditioning for transportation, transformation and manufacture of products at industrial complexes, and 
distribution to the end customer. In 2009, our technology unit allocated approximately U.S.$8.8 million to R&D activities, of which 
approximately 10% was allocated to cooperation with technology centers. Our management has decided to increase amounts allocated 
to this budget for the next years.  

R&D efforts are also focused on the development of enhanced oil recovery technologies, for the increased recovery of oil from 

fields in decline. Furthermore, the exploration of hydrocarbons of non-traditional or unconventional sources, in respect of which 
worldwide reserves are estimated to be superior to those hitherto exploited, remains one of YPF’s greatest R&D challenges, requiring 
the development and application of special technologies.  

With respect to the refinery and marketing of petroleum products, we apply our technological knowledge to optimize refinery 

operations and improve product quality, with a strong focus on achieving energy efficiency and environmental improvements.  

With respect to petrochemicals, technological development activities are mainly directed toward the development of new 
products with higher added value, such as special solvents, fertilizers and several agricultural products which use sulphur extracted 
from fuels.  

YPF works in cooperation with the R&D activities of Repsol YPF, to carry out development programs of mutual interest 
including prospects for new opportunities arising out of the long term evolution of the primary technologies used within the energy 
sector. These include bioengineering, future combustion engines, electric transport, the use of hydrogen as an energy carrier, 
renewable energy and the capture and storage of CO2 . These studies allow us and Repsol YPF to develop new capabilities and plan 
our future activities.  

Competition  

The deregulation and privatization process created a competitive environment in the Argentine oil and gas industry. In our 

Exploration and Production business, we encounter competition from major international oil companies and other domestic oil 
companies in acquiring exploration permits and production concessions. Our Exploration and Production business may also encounter 
competition from oil and gas companies created and owned by certain Argentine provinces, including La Pampa, Neuquén and 
Chubut, as well as from ENARSA, the Argentine state-owned energy company, especially in light of the transfer of certain 
hydrocarbon properties to ENARSA and the Argentine provinces in 2007. See “—Regulatory Framework and Relationship with the 
Argentine Government—Overview” and “—Regulatory Framework and Relationship with the Argentine Government—Law 
No. 26,197.” In our Refining and Marketing and Chemicals businesses, we face competition from several major international oil 
companies, such as ESSO (a subsidiary of ExxonMobil), Shell and Petrobras, as well as several domestic oil companies. In our export 
markets, we compete with numerous oil companies and trading companies in global markets.  

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 Argentine regulations and, accordingly, 
may fluctuate for a variety of reasons. Some of the prices in the internal market are controlled by local authorities. See “—Regulatory 
Framework and Relationship with the Argentine Government.” Changes in the domestic and international prices of crude oil and 
refined products have a direct effect on our results of operations and on our levels of capital expenditures. See “Item 3. Key 
Information—Risk Factors— Risks Relating to the Argentine Oil and Gas Business and Our Business—Oil and gas prices could affect 
our level of capital expenditures.”

Environmental Matters  

YPF—Argentine operations  

Our operations are subject to a wide range of laws and regulations relating to the general impact of industrial operations on the 
environment, including emissions into the air and 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 for 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.  

In 2009, we continued making investments in order to comply with new Argentine fuel specifications that are scheduled to come 

into effect gradually through 2016, pursuant to Resolution No. 1283/06 (amended by Resolution No. 478/2009) of the Argentine 
Secretariat of Energy (which replaces Resolution No. 398/03) relating to, among other things, the purity of diesel fuels. In addition, 
we have completed basic engineering packages and began detailed engineering studies for the construction of diesel fuel oil 
desulphuration units at La Plata and Luján de Cuyo refineries and FCC naphtha desulphuration unit in Luján de Cuyo refinery. These 
projects have been delayed due to the postponement of the implementation of the fuel specification regulations, but must be completed 
by July 2012. Construction strategies oriented to meet the July 2012 deadline have been adopted by us. In La Plata refinery, an FCC 
Naphtha Hydrotreater unit to reduce sulphur in gasoline was completed in 2007 and began operating in 2008.  

The basic engineering packages and detailed engineering studies for projects related to biofuels, such as the addition of 
bioethanol to gasoline and Fatty Acid Methyl Esters (FAME) to diesel, were developed during 2008. In 2009, bioethanol facilities at 
several terminals were installed and operational by the end of the same year. Also in 2009, investments were made in projects in La 
Plata, Luján de Cuyo and Plaza Huincul refineries to enable the addition of FAME to diesel, and all of them were operational by the 
beginning of 2010. These projects will enable YPF to comply with governmental requirements and to enter into the renewable energy 
sources market.  

In 2009, we approved a plan to comply with the above-mentioned motor fuels quality environmental specifications. This plan 

contemplates investments of approximately U.S.$710 million between 2010 and 2012.  

At each of our refineries, we are performing, on our own initiative, remedial investigations and feasibility studies and pollution 
abatement projects, which are designed to address liquid effluent discharges 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, we have 

initiated the construction of a Plant Continuous Catalytic Reformer (CCR) which will imply an investment of approximately U.S.$348 
million. The above plant will use the latest technology available worldwide to perform chemical processes which will involve 
improvements in productivity, safety and environmental standards. We estimate that the project will require approximately 3 years. 
The production system will produce about 200,000 additional tons of aromatics that can be used as octane enhancers for gasoline and 
automotive applications. Additionally, it will increase the hydrogen production in approximately 15,000 tons which will feed the fuel 
hydrogenation processes for increasing the fuel quality and reduce the sulfur content, further reducing the environmental impact of 
internal combustion engines.  

In addition to the projects related to the new fuel specification standards mentioned above, we have begun to implement a broad 

range of environmental projects in the domestic Exploration and Production and Refining and Marketing and Chemicals segments.  

Capital expenditures associated with domestic Exploration and Production environmental projects during 2009 were 

approximately U.S.$89.3 million and included expenditures relating to Health, Safety and Environment management systems, waste 
management, energy efficiency, biodiversity plans, remediation of well sites, tank batteries’ integrity and remediation of oil spills in 
the gathering systems of fields. Expenditures will also be made to improve technical assistance and training, and to establish 
environmental contamination remediation plans, air emissions monitoring plans and ground water investigation and monitoring 
programs.  

47 

 
  
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 refineries and harbor 
terminals as well.  

In 1991, we entered into an agreement (Convenio de Cooperación Interempresarial, or “CCI”) 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 facilities.  

Regarding climate change, as a part of Repsol YPF, YPF has actively contributed to Repsol YPF’s climate change strategies 

since 2002. Within Repsol YPF’s efforts on climate change, YPF is working on the following:  

•   actively promoting the identification and pursuit of opportunities to reduce greenhouse gas emissions within our 

operations;  

•   intensifying the execution of internal projects for generating 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;  

•   collaborating with competent authorities, in particular the Argentine Clean Development Mechanism Office 

(“OAMDL”);  

•   in July 2007, the United Nations Clean Development Mechanism Executive Board approved the methodology 

proposed by YPF for the recovery of waste gases from refinery flares, based on a project that is being developed at La 
Plata Industrial Complex. With its approval, the AM0055 “Baseline and Monitoring Methodology for the recovery and 
utilization of waste gas in refinery facilities” may serve as a reference for other companies in the sector. We have also 
requested the registration of this project with the United Nations, and an approval is expected during 2010;  

•   verifying the CO2 inventory of the Ensenada Industrial Complex under the ISO 14064 standard. The inventory was 

successfully verified in 2008 and verification of 2009 emissions is expected to be completed during 2010;  

•   we are seeking OAMDL’s approval for a project of flare gas recovery and utilization at Luján de Cuyo refinery; the 
validation process has already started and the project is expected to be registered during the first half of 2010;  

•   verification of emissions reductions in our refining operations according to the ISO 14064 standard.  

Our estimated capital expenditures and future investments are based on currently available information and on current laws, and 
new information or future changes in laws or technology could cause a revision of such estimates. In addition, while we do not expect 
environmental expenditures to have a significant impact on our future results of operations, 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.  

YPF Holdings—Operations in the United States  

Laws and regulations relating to health and environmental quality in the United States affect YPF Holdings’ operations in the 

United States. See “—Regulatory Framework and Relationship with the Argentine Government—U.S. Environmental Regulations.”  

In connection with the sale of Diamond Shamrock Chemicals Company (“Chemicals”) to a subsidiary of Occidental Petroleum 
Corporation (“Occidental”) in 1986, Maxus Energy Corporation (“Maxus”) agreed to indemnify Chemicals and Occidental from and 
against certain liabilities relating to the business and activities of Chemicals prior to the September 4, 1986 closing date (the “Closing 
Date”), including certain environmental liabilities relating to certain chemical plants and waste disposal sites used by Chemicals prior 
to the Closing Date.  

In addition, under the agreement pursuant to which Maxus sold Chemicals to Occidental, Maxus is obligated to indemnify 
Chemicals and Occidental for certain environmental costs incurred on projects involving remedial activities relating to chemical plant 
sites or other property used to conduct Chemicals’ business as of the Closing Date and for any period of time following the Closing 
Date which relate to, result from or arise out of conditions, events or circumstances discovered by Chemicals and as to which 
Chemicals provided written notice prior to September 4, 1996, irrespective of when Chemicals incurs and gives notice of such costs.  

Tierra Solutions Inc. (“Tierra”) was formed to deal with the results of the alleged obligations of Maxus, as described above, 

resulting from actions or facts that occurred primarily between the 1940s and 1970s while Chemicals was controlled by other 
companies.  

48 

 
  
See “Item 8. Financial Information—Legal Proceedings—YPF Holdings” below for a description of environmental matters in 

connection with YPF Holdings.  

Property, Plant and Equipment  

Most of our property, consisting of interests in crude oil and natural gas reserves, refineries, storage, manufacturing and 
transportation facilities and service stations, is located in Argentina. We also own property in the United States. See “—Exploration 
and Production—Principal properties.”  

There are several classes of property which we do not own in fee. 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. In addition, as of December 31, 
2009, we leased 89 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.  

Regulatory Framework and Relationship with the Argentine Government  
Overview  

The Argentine oil and gas industry has been and continues to be subject to certain policies and regulations that have resulted in 

domestic prices that are, in some cases, substantially lower than prevailing international market prices, export restrictions, 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, and increasingly heavy export duties on the volumes of hydrocarbons allowed to be exported. These governmental 
pricing limitations, export controls and tax policies have been implemented in an effort to satisfy increasing domestic market demand 
at prices below international market prices.  

The Argentine oil and gas industry is regulated by Law No. 17,319, referred to as the “Hydrocarbons Law,” which was adopted 

in 1967 and amended by Law No. 26,197 in 2007, 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.  

The executive branch of the Argentine government 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, Law No. 24,145, referred to as 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 square kilometers and 50 production 
concessions covering approximately 32,560 square kilometers. The Hydrocarbons Law limits to five the number of concessions that 
may be held by any one entity, and also limits the total area of exploration permits that may be granted to a single entity. Based on our 
interpretation of the law, we were exempted from such limit with regard to the exploration permits and production concessions 
awarded to us by the Privatization Law. Nevertheless, the National Department of Economy of Hydrocarbons (Dirección Nacional de 
Economía de los Hidrocarburos), applying a restrictive interpretation of Section 25 and 34 of the Hydrocarbons Law, has objected to 
the award of new exploration permits and production concessions in which we have a 100% interest. As a result, our ability to acquire 
100% of new exploration permits and/or production concessions has been hindered, although this interpretation has not impeded our 
ability to acquire any permits or concessions where an interest is also granted to other parties. As a consequence of the transfer of 
ownership of certain hydrocarbons areas to the provinces, we participate in competitive bidding rounds organized since the year 2000 
by several provincial governments for the award of contracts for the exploration of hydrocarbons.  

In October 2004, the Argentine Congress enacted Law No. 25,943 creating a new state-owned energy company, Energía 

Argentina S.A. (“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).  

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 

49 

 
  
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.  

Law No. 26,197  

Law No. 26,197, which amended the Hydrocarbons Law, transferred to the provinces and the 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 all of 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 which 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 government retained the power to determine the national energy policy.  

It is expressly stated that the transfer will not affect the rights and obligations of exploration permit and production concession 
holders, or the basis for the calculation of royalties, which shall be calculated in accordance with the concession title and paid to the 
province where the reservoirs are located.  

Law No. 26,197 provides that the Argentine government shall retain the authority to grant transportation concessions for: 
(i) transportation concessions located within two or more provinces 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.  

Public Emergency  

On January 6, 2002, the Argentine Congress enacted Law No. 25,561, the Public Emergency and Foreign Exchange System 

Reform Law (“Public Emergency Law”), which represented a profound change of 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 the executive branch of the Argentine government authority to enact all 
necessary regulations in order to overcome the economic crisis in which Argentina was then immersed.  

50 

 
  
After the enactment of the Public Emergency Law, several other laws and regulations have been enacted. The following are the 

most significant measures enacted to date in Argentina to overcome the economic crisis:  

•   Conversion into pesos of (i) all funds deposited in financial institutions at an exchange rate of Ps.1.40 for each U.S.$1.00 and 
(ii) all obligations (e.g., loans) with financial institutions denominated in foreign currency and governed by Argentine law at 
an exchange rate of Ps.1.00 for each U.S.$1.00. The deposits and obligations converted into pesos would be thereafter 
adjusted by a reference stabilization index, the Coeficiente de Estabilidad de Referencia (“CER”), to be published by the 
Argentine Central Bank. Obligations governed by non-Argentine law have not been converted to pesos under the new laws. 
Substantially all of our dollar-denominated debt is governed by non-Argentine law.  

•   Conversion into pesos at an exchange rate of Ps.1.00 for each U.S.$1.00 of all obligations outstanding among private parties 
at January 6, 2002 that are governed by Argentine law and payable in foreign currency. The obligations so converted into 
pesos would be adjusted through the CER index, as explained above. In the case of non-financial obligations, if as a result of 
the mandatory conversion into pesos the resulting intrinsic value of goods or services that are the object of the obligation are 
higher or lower than their price expressed in pesos, either party may request an equitable adjustment of the price. If they 
cannot agree on such equitable price adjustment, either party may resort to the courts. Executive Decree No. 689/02 
established an exception to the Public Emergency Law and regulations and provides that the prices of long-term natural gas 
sale and transportation agreements executed before the enactment of the Decree and denominated in U.S. dollars will not be 
converted into pesos (Ps.1.00 for each U.S.$1.00) when the natural gas is exported.  

•   Conversion into pesos at an exchange rate of Ps.1.00 for each U.S.$1.00 of all tariffs of public services, the elimination of the 
adjustment of tariffs by foreign indexes such as the Purchaser Price Index (PPI)/Consumer Price Index (CPI) index, and the 
imposition of a period of renegotiation with the governmental authorities thereafter.  

•   Imposition of customs duties on the export of hydrocarbons with instructions to the executive branch of the Argentine 

government to set the applicable rate thereof. See also “—Taxation” below.  

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 executive branch of the Argentine government 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 Secretariat of Energy 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 granted to third parties in connection with the deregulation and demonopolization process 
were granted in accordance with procedures specified in Executive Decrees No. 1055/89, 1212/89 and 1589/89 (the “Oil Deregulation 
Decrees”), and permits covering areas in which our predecessor company, Yacimientos Petrolíferos Fiscales S.A., was operating at the 
date of the Privatization Law and that were granted to us by such law. In 1991, the executive branch of the Argentine government 
established a program under the Hydrocarbons Law (known as Plan Argentina) pursuant to which exploration permits were auctioned. 
The holder of an exploration permit has the exclusive right to perform the operations necessary or appropriate for the exploration of 
oil and gas within the area specified by the permit. Each exploration permit may cover only unproved areas not to exceed 10,000 
square kilometers (15,000 square kilometers 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 revert 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.  

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 provides that oil and 
gas production concessions shall remain in effect for 25 years as from the date of the award of the production concession, in addition 
to any remaining exploration term at the date of such award. The Hydrocarbons Law further provides for the concession term to be 
extended for up to 10 additional years, subject to terms and conditions approved by the grantor at the time of the extension. Under 
Law No. 26,197, the authority to extend the terms of current and new permits and concessions and has been vested in the governments 

51 

 
  
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. Upon the expiration of the 10-year extension period of the current concessions, the provinces 
are entitled to award new concessions or contracts in respect of the relevant blocks.  

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” below.  

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. A 12% royalty, and an additional 3% royalty in certain concessions for which the expiration has 
been extended (see “—Extension of Exploitation Concessions in the province of Neuquén” below), is 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 the natural gas volumes commercialized. 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 Resolution S.E. 435/2004 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.  

Considering, among other things, that as a result of Resolution 394/2007 of the Ministry of Economy and Production, 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 calculation of royalties, the Undersecretariat of Fuels, which depends on the 
Argentine Secretariat of Energy, passed Disposition No. 1, which sets a minimum reference price for the calculation of royalties and 
does not permit downward adjustments of this price based upon the quality of crude oil. As of the date of this annual report, we have 
negotiated with certain third parties sale prices of crude oil that we have used as the basis for calculating and paying royalties 
according to the methodology set forth in the Hydrocarbons Law.  

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 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. 
Additionally, Executive Decree No. 1,454/07, dated October 17, 2007, increased the amount of exploration and production surface 
fees expressed in Argentine pesos that are payable to the provinces in which the hydrocarbon fields are located or, in the case of 
offshore and certain other fields, to the Argentine government.  

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;  

52 

 
  
•   bankruptcy of the permit or concession holder;  
•   death or end of legal existence of the permit or concession holder; or  
•   failure to transport hydrocarbons for third parties on a non-discriminatory basis or repeated violation of the authorized tariffs 

for such transportation.  

The Hydrocarbons Law further provides that a cure period, of a duration to be determined by the 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 government in the case of reservoirs under 
federal jurisdiction (i.e., located on the continental shelf or beyond 12 nautical miles offshore), without compensation to the holder of 
the concession.  

Certain of our production concessions expire in 2017. 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 provides that 
applications must be submitted at least six months 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 Resolution S.E. No. 324/06 establishing 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 Resolution S.E. 
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—Oil and Gas Reserves.”  

In March 2007, the Argentine Secretariat of Energy issued Resolution No 407/2007 which approved new regulations concerning 

the Oil and Gas Exploration and Production Companies Registry. According to Resolution No 407/2007, 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.  

Extension of Exploitation Concessions in the province of Neuquén  
In addition to the extension in 2002 of the expiration date of the exploitation concession of Loma La Lata field until 2027, 
during the years 2008 and 2009, YPF entered into a number of agreements with the province of Neuquén, pursuant to which the 
exploitation concession terms of several areas located within the province were extended for a 10-year term, which now expire 
between 2026 and 2027. As a condition to the extension of the concession terms, YPF has undertaken to do the following under the 
relevant agreements: (i) to make initial payments to the province of Neuquén in an aggregate amount of approximately U.S.$204 
million; (ii) to pay the province of Neuquén an “Extraordinary Production Royalty” of 3% of the production of the areas affected by 
this extension (in addition, the parties agreed to make additional adjustments of up to an additional 3% in the event of extraordinary 
income, as defined in each agreement); (iii) to carry out exploration activities in the remaining exploration areas and make certain 
investments and expenditures until the expiration of the concessions in an aggregate amount of approximately U.S.$3,512 million, and 
(iv) to make “Corporate Social Responsibility” contributions to the province of Neuquén in an aggregate amount of approximately 
U.S.$23 million.  

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). 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, such as is currently the case, for any additional 
acquisition of real estate, mineral rights, oil or other Argentine government concessions located within, or with respect to, 
security zones.  

Because approval of Class A shareholders is required for a change in our control under our by-laws, and approval of the 
executive branch of the Argentine government or provincial governments is required for the grant or transfer of hydrocarbon permits 
and concessions, we believe that possible additional requirements under the security zone legislation will not have a significant impact 
on our operations.

Natural Gas Transportation and Distribution  

In June 1992, the Natural Gas Law was passed, providing for the privatization of Gas del Estado Sociedad del Estado (“Gas del 
Estado”) and the deregulation of the price of natural gas. To effect the privatization of Gas del Estado, the five main trunk lines of the 
gas transmission system were divided into two systems principally on a geographical basis (the northern and the southern trunk 
pipeline systems). This was designed to give both systems access to gas sources and to the main centers of demand in and around 
Buenos Aires. These systems were transferred into two new transportation companies. The Gas del Estado distribution system was 
divided into eight regional distribution companies, including two distribution companies serving the greater Buenos Aires area. Shares 
of each of the transportation and distribution companies were sold to consortiums of private bidders. Likewise, in 1997, a distribution 
license for the provinces of Chaco, Formosa, Entre Ríos, Corrientes and Misiones was granted to private bidders.  

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 have 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 Nos. 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. See “—Market Regulation—Natural gas export restrictions and domestic supply 
priorities.”  

Transportation of Liquid Hydrocarbons  

The Hydrocarbons Law permits 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. 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 executive branch. 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 the National Gas Regulatory 
Authority (Ente Nacional Regulador del Gas or “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 S.A. at the 
time. Gas pipelines and distribution systems sold in connection with the privatization of Gas del Estado are subject to a different 
regime under the Natural Gas Law.  

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 executive branch 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 the 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.  

Executive Decree No. 2014/2008 of November 25, 2008, created the “Refining Plus” program to encourage the production of 
diesel fuel and gasoline. The Argentine Secretariat of Energy, by Resolution S.E. No. 1312/2008 of December 1, 2008, approved the 
regulations of the program. Refining companies that undertake the construction of a new refinery or the expansion of their refining 

54 

 
and/or conversion capacity, whose plans are approved by the Argentine Secretariat of Energy, will be entitled to receive export duty 
credits to be applied to exports of products within the scope of Resolution No. 394/2007 and Resolution No. 127/2008 (Annex) issued 
by the Department of Economy and Production.  

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 dispose of such production in the domestic or export markets, in each 
case subject to the conditions described below.  

The Hydrocarbons Law authorizes the executive branch of the Argentine government to regulate the Argentine oil and gas 

markets and prohibits the export of crude oil during any period in which the executive branch finds domestic production to be 
insufficient to satisfy domestic demand. If the executive branch restricts the export of crude oil and petroleum products or the free 
disposition of natural gas, the Oil Deregulation Decrees provide that producers, refiners and exporters shall receive a price:  

•   in the case of crude oil and petroleum products, not lower than that of imported crude oil and petroleum products of similar 

quality; and  

•   in the case of natural gas, not less than 35% of the international price per cubic meter of Arabian light oil, 34° API.  

Furthermore, the Oil Deregulation Decrees expressly required the executive branch to give twelve months’ notice of any future 

export restrictions. Notwithstanding the above provisions, certain subsequently-enacted Resolutions (Resolution S.E. 1679/04, 
Resolution S.E. 532/04 and Resolution of the Ministry of Economy and Production 394/2007) have modified the aforementioned price 
mechanism, resulting, in certain cases, in prices to producers below the levels described above.  

Production of crude oil and reserves  

Executive Decree No. 2014/2008 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, 
by Resolution S.E. No. 1312/2008 of December 1, 2008, approved the regulations of the program. The program entitles production 
companies, whose plans are approved by the Argentine Secretariat of Energy, which increase their production and reserves within the 
scope of the program, to receive export duty credits to be applied to exports of products within the scope of Resolution No. 394/2007 
and Resolution No. 127/2008 (Annex) issued by the Department of Economy and Production.  

Refined products  

In April 2002, the Argentine government and the main oil companies, 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 Fuel (Convenio 
de Estabilidad de Suministro de Gas Oil) was approved by Executive Decree No. 652/02 and assured the transportation companies 
their necessary supply of diesel fuel 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 the fixed price and the market price through 
export duty credits. Through new price-stabilization agreements, the price paid by urban and suburban transporters was revised, the 
current price being Ps.0.80 per liter. In March 2009, Executive Decree No. 1390/2009 empowered the Chief of Cabinet to sign annual 
agreements extending the diesel fuel 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, 
and in defect thereof, in cash. As of the date of this annual report, the annual agreement for the fiscal year 2009 is pending signature.  

The Argentine Secretariat of Energy has issued a series of resolutions affecting the fuel market. For example, Resolution S.E. 
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; Resolution S.E. 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 by fuel manufacturers 
and by sellers; Resolution S.E. 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; and Resolution S.E. 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 overcosts to the refining company.  

55 

 
  
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.  

Resolution S.E. No. 1,679/04 reinstalled the registry of diesel fuel 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 fuel 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 S.E. No. 1338/06 added other petroleum products to the 
registration regime created by Executive Decree No. 645/2002, including gasoline, fuel oil and its derivatives, aviation fuel, coke coal, 
asphalts, certain petrochemicals and certain lubricants. Resolution No. 715/2007 of the Argentine Secretariat of Energy empowered 
the National Refining and Marketing Director to determine the amounts of diesel fuel 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 fuel is necessary to obtain authorization to export the products included under Decree No. 645/2002 (crude, 
fuel oil, diesel fuel, 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 fuel demand, by supplying certain minimum volumes (established pursuant to the resolution) to their usual 
customers, mainly service station operators and distributors.  

Resolution S.E. No. 459/07, of July 12, 2007, created the “Energy Substitution Program”, intended to mitigate gas and 
electricity shortages. This program encouraged industrial users to substitute natural gas and electricity use with diesel, fuel oil and 
LPG.  

Resolution No. 1451/2008 extended until December 31, 2009 the Energy Substitution Program and Rule No. 287/2008, issued 

by the Sub-secretary of Coordination and Control on December 19, 2008, which approved the following general plans for the 
implementation of the Energy Substitution Program in 2009:  

1) General Plan for the Supply of Gaseous Fuels, including:  

(i) a plan for the supply of regasified liquefied natural gas (LNG), which provided for the construction, maintenance, 
management and administration of a system for the regasification of LNG and the supply of natural gas to the Argentine market, 
and empowered ENARSA, directly or through third parties, to take all necessary actions, including the purchase of the LNG, for 
such purpose;  
(ii) a plan for the supply of propane, which provided for the management of a system to acquire and deliver propane to be 
injected into the natural gas distribution network of the province of Buenos Aires, and empowered ENARSA, directly or 
through third parties, to take all necessary actions, including the purchase of propane, for such purpose; and  
(iii) a plan for the provision of imported gas deemed necessary to fulfill the objectives of the Energy Substitution Program. In 
this respect, ENARSA was to purchase the natural gas necessary to fulfill domestic demand.  

2) General Plan for the Supply Liquid Fuels, including:  

(i) a plan designed to guarantee that demand for liquid fuel in the Argentine market was met. For such purpose, ENARSA, 
directly or through third parties, was empowered to buy and sell liquid fuels; and  
(ii) a plan to encourage and subsidize replacement of natural gas and/or electric power consumption with the use of alternative 
fuels in productive activities and/or electric power generation through an efficient use of gas. ENARSA, directly or through 
third parties, was empowered to manage the mechanisms for the supply of liquid fuels to replace the natural gas.  
The Energy Substitution Program has recently been extended for the year 2010.  

Natural gas  

In January 2004, Executive Decree No. 180/04 (i) created the Mercado Electrónico del Gas (MEG) for the trade of daily spot 
sales of gas and a secondary market of transportation and distribution services and (ii) established information duties 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.  

56 

 
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. On April 2, 2004, the 
Argentine Secretariat of Energy and gas producers signed an agreement which was ratified by Resolution No. 208/04 issued by the 
Ministry of Federal Planning, Public Investment and Services. The aim of the agreement was to implement a scheme for the 
normalization of natural gas prices following the 2001 crisis. The main aspects of the agreement were: (i) initial price adjustments 
applied exclusively to gas supplied by producers to industrial users, new direct consumers and electricity generators (to the extent that 
electricity was destined for the domestic market); (ii) prices were adjusted as of May 10, 2004; and (iii) the Argentine Secretariat of 
Energy would implement a progressive scheme for the normalization of the price of natural gas destined to residential end-users and 
small commercial users, which was never implemented. This agreement expired on December 31, 2006.  

On June 14, 2007, Resolution No. 599/07 of the Argentine Secretariat of Energy approved a proposal of agreement with natural 

gas producers regarding the supply of natural gas to the domestic market during the period 2007 through 2011 (the “Propuesta de 
Acuerdo,” or “Agreement 2007-2011”), giving such producers a five-business-day term to enter into the Agreement 2007-2011. If 
within that term, the Agreement 2007-2011 was not executed by a sufficient number of producers to make it viable, the Argentine 
Secretariat of Energy would disregard the Agreement and enact the Procedures for Complementary Supply of the Internal Market 
2007-2011 (Procedimientos de Abastecimiento Complementario al Mercado Interno 2007-2011) (not described in Resolution 
No. 599/07). We executed the agreement taking into account that natural gas exports and certain domestic sales of producers that do 
not enter into the Agreement 2007-2011 are to be called upon first in order to satisfy domestic demand, before the export sales of the 
producers that have signed the Agreement 2007-2011 are affected. While producers are authorized to withdraw from the Agreement 
2007-2011 under its terms, if they do so such producers will be treated as any producer that has not entered into the Agreement 2007-
2011 in the first place.  

The purpose of the Agreement 2007-2011 is 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 (the “agreed demand levels”). Producers that have 
entered into the Agreement 2007-2011 would commit to supply a part of the agreed demand levels according to certain shares 
determined for each producer based upon its share of production for the 36 months prior to April 2004. For this period, our share of 
production was approximately 36.5%, or 36.8 mmcm/d (or 1,300 mmcf/d). The Agreement 2007-2011 also provides guidelines for the 
terms of supply agreements for each market segment, and certain pricing limitations for each market segment of the agreed demand 
levels. In order to guarantee any domestic market demand of natural gas in excess of the agreed demand levels, Resolution S.E. 
No. 599/07 maintains the effectiveness of the Resolutions that implemented the curtailment of natural gas export commitments and the 
re-routing of such natural gas volumes to certain sectors of the domestic market. See “—Natural gas export restrictions and domestic 
supply priorities.” The Resolution also states that the Agreement 2007-2011 does not prevent the possible suspension or termination of 
export permits.  

We were compelled to execute the Agreement 2007-2011, among other reasons, in order to mitigate our potential damages. 

Producers failing to sign the Agreement 2007-2011 could be penalized and subject to other unfavorable measures by regulatory 
authorities. However, we expressly stated that the execution of the 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 the 
Agreement 2007-2011 taking into account the potential consequences of not doing so.  

The Department of Federal Planning, Public Investment and Services, by its Resolution S.E. No. 459/07 of July 12, 2007, 
created the “Energy Substitution Program,” which was designed to mitigate shortages of gas and electricity during the Argentine 
winter of 2007. The program encouraged industrial users to substitute natural gas and electricity use with diesel, fuel oil and LPG.  

The Argentine Secretariat created, by its Resolution No. 24/2008 issued on March 13, 2008, a program named “Gas Plus” to 

encourage natural gas production resulting from new reserves discoveries, new fields and tight gas, among other factors. The natural 
gas produced under the Gas Plus program will not be subject to the Agreement 2007-2011 and will not be subject to the price 
conditions established under such Agreement.  

The Argentine Secretariat of Energy, through Resolution No. 1031/2008 issued on September 12, 2008, modified Resolution 
No. 24/2007, 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. 695/2009 of the Argentine Secretariat of Energy, which demands compliance with 
commitments already assumed.  

The Argentine Secretariat of Energy, through Resolution No. 1070/2008 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. On January 13, 2010 the natural gas producers signed an addendum to the Complementary Agreement which extends the 
commitment to contribute to the fiduciary funds created by Law No. 26,020 until December 31, 2010. See “—Liquefied Petroleum 
Gas.”  

57 

 
Additionally, Executive Decree No. 2067/2008 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 will be 
funded through the following mechanisms: (i) various tariff charges to be 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. To date, the competent authorities have only imposed the tariff on users of transport 
and distribution services. This decree has been subject to different judicial claims and judges throughout the country have issued 
precautionary measures suspending its effects. Through Resolution N° 1.417/2008, the Secretariat of Energy determined the new basin 
prices for the residential segment applicable to the producers that signed the Complementary Agreement.  

On July 17, 2009, the Ministry of Federal Planning, Public Investment and Services and certain natural gas producers (including 
YPF) signed an agreement which set 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. The previously mentioned amounts will be adjusted monthly so that the resulting amounts represent 50% of the amount 
collected by the fiduciary fund to finance natural gas imports.  

Through Resolution 828/2009, ENARGAS ordered natural gas distributors to reinvoice and return to consumers certain tariff 

charges collected from them according to Executive Decree No. 2067/2008 (in different percentages). The ENARGAS Resolution was 
applicable to natural gas consumptions by residential consumers during the period between May 1 and September 30, 2009.  

Natural gas export restrictions and domestic supply priorities  

In March 2004, the Argentine Secretariat of Energy issued Resolution S.E. 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 surpluses of 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  

•   authorizing 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 Resolution S.E. No. 265/04, issued 

Regulation S.S.C. No. 27/04 establishing a rationalization plan of gas exports and transportation capacity. Among other things, 
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 Resolution S.E. No. 659/04, which established a new program to assure 

natural gas supply to the domestic market (which substitutes for the program created by Regulation No. S.S.C. 27/04). Under 
Resolution S.E. No. 659/04 (amended by Resolution S.E. 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 Resolution S.E. 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, Resolution S.E. No. 659/04 and Resolution S.E. No. 752/05, the Argentine Secretariat of 
Energy and/or the Undersecretariat of Fuels have instructed us to re direct 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.”  

Resolution S.E. 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.  

58 

 
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. Resolution of the Argentine Secretariat of Energy S.E. No. 1886/2006, published on 
January 4, 2007, extended the term of effectiveness of this mechanism of standardized irrevocable offers until 2016, and empowered 
the Undersecretariat of Fuels to suspend its effectiveness subject to the satisfaction of internal demand of natural gas achieved by 
means of regulations, agreements or due to the discovery of reserves.  

By means of Resolution S.E. No. 1329/06, later supplemented by Note SSC No. 1011/07, the Argentine Secretariat of Energy 

forced producers to give first priority in their injections of natural gas into the gas pipelines to certain preferential consumers and 
obligates 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 of gas producers as well as 

the transportation companies received instructions from the government to cut off exports, except for certain volumes addressed to 
satisfy Chilean residential consumptions and other specific consumptions.  

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;  

•   required 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);  

•   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 
will be funded through the following mechanisms: (i) penalties established by Law 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. The Argentine 
Secretariat of Energy in 2007 increased the LPG volumes to be sold to bottlers at the reference prices set forth in the above-mentioned 
resolutions.  

Disposition 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 an agreement for the stability of 

the price of LPG in the domestic market (the “Complementary Agreement”). 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 Agreement requires LPG 
producers to supply LPG bottlers with the same volume of LPG supplied the prior year and to accept the price per ton set forth in the 
Complementary Agreement. The Complementary Agreement was extended on October 23, 2009 pursuant to an addendum entered 
into by YPF and Repsol YPF Gas S.A. The addendum requires LPG producers to supply LPG bottlers in 2010 with the same volume 
provided during 2009 plus an additional 5%. This addendum expires on December 31, 2010.

Argentine Environmental Regulations  

The enactment of Articles 41 and 43 in the National Constitution, as amended in 1994, as well as new federal, provincial and 

municipal legislation, has strengthened the legal framework dealing with damage to the environment. Legislative and government 
agencies have become more vigilant in enforcing the laws and regulations regarding the environment, increasing sanctions for 
environmental violations.  

Under the amended Articles 41 and 43 of the National Constitution, all Argentine inhabitants have both the right to an 
undamaged environment and a duty to protect it. The primary obligation of any person held liable for environmental damage is to 
rectify such damage according to and within the scope of applicable law. The federal government sets forth the minimum standards 
for the protection of the environment and the provinces and municipalities establish specific standards and implementing regulations.  

Federal, provincial and municipal laws and regulations relating to environmental quality in Argentina affect our operations. 
These laws and regulations set standards for certain aspects of environmental quality, provide for penalties and other liabilities for the 
violation of such standards, and establish remedial obligations in certain circumstances.  

In general, we are subject to the requirements of the following federal environmental regulations (including the regulations 

issued thereunder):  

•   National Constitution (Articles 41 and 43);  
•   Law No. 25,675 on National Environmental Policy;  
•   Law No. 25,612 on Integrated Management of Industrial and Service Industry Waste;  
•   Law No. 24,051 on Hazardous Waste;  
•   Law No. 20,284 on Clean Air;  
•   Law No. 25,688 on Environmental Management of Waters;  
•   Law No. 25,670 on the Management and Elimination of Polychlorinated Biphenyls;  
•   Criminal Code; and  
•   Civil 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 is established in relation to 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 works 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 Law No. 22,145.  

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. We have commenced the development and implementation of a technical and environmental 
audit plan as required by this Resolution.

The above 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.  

U.S. Environmental Regulations  

In addition, federal, state and local laws and regulations relating to health, safety and environmental quality in the United States, 

where YPF Holdings Inc. (“YPF Holdings”) operates, affect the operations of this subsidiary. YPF Holdings’ U.S. operations, 
conducted primarily through Maxus Energy Corporation (“Maxus”), are subject to the requirements of the following U.S. 
environmental laws:  

•   Safe Drinking Water Act;  
•   Clean Water Act;  
•   Oil Pollution Act;  
•   Clean Air Act;  
•   Resource Conservation and Recovery Act;  
•   National Environmental Policy Act;  
•   Occupational Safety and Health Act;  
•   Comprehensive Environmental Response, Compensation and Liability Act; and  
•   various other federal, state and local laws.  

These laws and regulations set various standards for many aspects of health, safety and environmental quality (including limits 

on discharges associated with oil and gas operations), provide for fines and criminal penalties and other consequences (including 
limits on operations and loss of applicable permits) for the violation of such standards, establish procedures affecting location of 
facilities and other operations, and in certain circumstances impose obligations concerning reporting, investigation and remediation, as 
well as liability for natural resource damages and toxic tort claims.  

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. 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 executive branch of the Argentine government 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.  

61 

 
  
  
Export taxes  

In 2002, the Argentine government began to impose customs duties on the export of hydrocarbons. Export tax rates were 

increased on crude oil to 20%, on butane, methane and LPG to 20% and gasoline and diesel fuel to 5%. In May 2004, Resolution 
No. 337/04 of the Ministry of Economy and Production increased export duties on crude oil to 25%. These export tax rates were 
increased again in 2004, when the Ministry of Economy and Production issued Resolution No. 532/04, establishing a progressive 
scheme of export duties for crude oil, with rates ranging from 25% to 45%, depending on the quotation of the WTI reference price at 
the time of the exportation. In addition, in May 2004, pursuant to Resolution No. 645/04 of the Ministry of Economy and Production, 
an export duty on natural gas and natural gas liquids was established at a rate of 20%. The export duty on natural gas was increased 
again in July 2006, when the Ministry of Economy and Production increased the rate to 45% and instructed the Customs General 
Administration to apply the price fixed by the Framework Agreement between Argentina and Bolivia as the base price to which to 
apply the new tax rate, irrespective of the actual sales price. In addition, on October 10, 2006, the Ministry of Economy and 
Production imposed prevalent export duties on exports from the Tierra del Fuego province, which were previously exempted from 
taxes. Moreover, in May 2007 the Ministry of Economy and Production increased to 25% the export duty on butane, propane and 
LPG. There can be no assurances as to future levels of export taxes.  

Resolution No. 394/2007 of the Ministry of Economy and Production, effective as of November 16, 2007, increased export 

duties on Argentine oil exports (as defined by the regulator) on crude oil and other crude derivatives products. The new regime 
provides that when the WTI international price exceeds the reference price, which is fixed at U.S.$60.9/barrel, the producer shall be 
allowed to collect at U.S.$42/barrel, with the remainder being withheld by the Argentine government as an export tax. If the WTI 
international price is under the reference price but over U.S.$45/barrel, a 45% withholding rate will apply. If such price is under 
U.S.$45/barrel, the applicable export tax is to be determined by the Argentine government within a term of 90 business days. 
Resolution No. 127/2008 of the Ministry of Economy and Production increased export duties applicable to natural gas exports from 
45% to 100%, mandating a valuation basis for the calculation of the duty as the highest price established in any contract of any 
Argentine importer for the import of gas (abandoning the previously applicable reference price set by the Framework Agreement 
between Argentina and Bolivia mentioned above). Resolution No. 127/2008 provides with respect to LPG products (including butane, 
propane and blends thereof) that if the international price of the relevant LPG product, as notified daily by the Argentine Secretariat of 
Energy, is under the reference price established for such product in the Resolution (U.S.$338/m3 for propane, U.S.$393/m3 for butane 
and U.S.$363/m3 for blends of the two), the applicable export duty for such product will be 45%. If the international price exceeds the 
reference price, the producer shall be allowed to collect the maximum amount established by the Resolution for the relevant product 
(U.S.$233/m3 for propane, U.S.$271/m3 for butane and U.S.$250/m3 for blends of the two), with the remainder being withheld by the 
Argentine government as an export tax.  

In addition, the calculation procedure described above also applies to other petroleum products and lubricants based upon 

different withholding rates, reference prices and prices allowed to producers. See “—Market Regulation.”  

Antitrust Agreement  

On June 16, 1999, the Argentine Ministry of Economy and Public Works delivered a letter to Repsol YPF setting forth a series 

of obligations that Repsol YPF was required to assume after the acquisition of the majority of our share capital. Repsol YPF met all of 
the requirements upon execution of the asset swap agreement entered into with Petrobras in December 2001. Repsol YPF believes that 
the acquisition of YPF will not be subject to further antitrust scrutiny in Argentina under existing law. However, the Ministry has not 
stated that there will be no further antitrust scrutiny and no assurances can be given that Repsol YPF will not be required to accept 
additional undertakings or other measures intended to address any perceived anti-competitive effects of the YPF acquisition.  

Repatriation of Foreign Currency  

Executive Decree No. 1,589/89, relating to the deregulation of the upstream oil industry, allows us and other companies engaged 

in oil and gas production activities in Argentina to freely sell and dispose of the hydrocarbons they produce. Additionally, under 
Decree No. 1,589/89, we and other oil producers are entitled to keep out of Argentina up to 70% of foreign currency proceeds they 
receive from crude oil and gas export sales, but are required to repatriate the remaining 30% through the exchange markets of 
Argentina.  

In July 2002, Argentina’s Attorney General issued an opinion (Dictamen No. 235) which would have effectively required us to 
liquidate 100% of our export receivables in Argentina, instead of the 30% provided in Decree No. 1,589/89 based on the assumption 
that Decree No. 1,589/89 had been superseded by other decrees (Decree No. 530/91 and 1,606/01) issued by the government. 
Subsequent to this opinion, however, the government issued Decree No. 1,912/02 ordering the Central Bank to apply the 70%/30% 
regime set out in Decree No. 1,589/89. Nevertheless, the uncertainty generated by the opinion of Argentina’s Attorney General 
resulted in a legal proceeding described under “Item 8. Financial Information—Legal proceedings—Argentina—Non-reserved, remote 
contingencies—Proceedings related to foreign currency proceeds”.

ITEM  5.  Operating and Financial Review and Prospects  

The following discussion should be read in conjunction with our audited consolidated financial statements as of December 31, 

2009, 2008 and 2007 and for the years then ended (the “Audited Consolidated Financial Statements”).  

Overview  

We are Argentina’s leading energy company, operating a fully integrated oil and gas chain with leading market positions across 
the domestic upstream and downstream segments. Our upstream operations consist of the exploration, development and production of 
crude oil, natural gas and liquefied petroleum gas. 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. In 2009, we had consolidated net sales of Ps.34,320 million (U.S.$9,032 million) and consolidated net income of Ps.3,486 
million (U.S.$917 million).  

Most of our predecessors were state-owned companies with operations dating back to the 1920s. 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.  

Since 1999, we have been controlled by Repsol YPF, an integrated oil and gas company headquartered in Spain with global 
operations. Repsol YPF owned approximately 99% of our capital stock from 2000 until 2008, when the Petersen Group purchased, in 
different stages, shares representing 15.46% of our capital stock. In addition, Repsol YPF granted certain affiliates of Petersen Energía 
an option to purchase up to an additional 10% of our outstanding capital stock. This option will expire on February 21, 2012. See 
“Item 7. Major Shareholders and Related Party Transactions.”  

Upstream Operations  

•   We operate more than 70 oil and gas fields in Argentina, accounting for approximately 39% of the country’s total production 
of crude oil, excluding natural gas liquids, and approximately 39% of its total natural gas production, including natural gas 
liquids, in 2009, according to information provided by the Argentine Secretariat of Energy.  

•   We had proved reserves, as estimated as of December 31, 2009, of approximately 538 mmbbl of oil and 2,672 bcf of gas, 

representing aggregate reserves of 1,013 mmboe.  

•   In 2009, we produced 111 mmbbl of oil (302 mbbl/d) and 533 bcf of gas (1,460 mmcf/d).  

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). We also have a 50% interest in 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, 2009 consisted of 1,632 YPF-branded 

service stations, which we estimate represented approximately 30.9% of all 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 plant and Plaza Huincul sites. In addition, Profertil S.A. (“Profertil”), a company that we 
jointly control with Agrium Investments Spain S.L. (“Agrium”), is one of the leading producers of urea in the Southern 
Cone.  

Presentation of Financial Information  

We prepare our audited consolidated financial statements in accordance with Argentine GAAP, which differ in certain 
significant respects from U.S. GAAP. Notes 13, 14 and 15 to the Audited Consolidated Financial Statements provide a summary of 
the effect of these significant differences on net income and shareholders’ equity under Argentine GAAP and U.S. GAAP.  

We fully consolidate the results of subsidiaries in which we have a sufficient number of voting shares to control corporate 

decisions and proportionally consolidate the results of companies that we control jointly.  

63 

 
  
Under Argentine GAAP, we currently are not required to record the effects of inflation in our financial statements. However, 

because Argentina experienced a high rate of inflation in 2002, with the wholesale price index increasing by approximately 118%, we 
were required by Decree No. 1269/2002 and CNV Resolution No. 415/2002 to remeasure our financial statements in constant pesos in 
accordance with Argentine GAAP. On March 25, 2003, Decree No. 664/2003 rescinded the requirement that financial statements be 
prepared in constant currency, effective for financial periods on or after March 1, 2003. According to the Argentine statistics and 
census agency (Instituto Nacional de Estadísticas y Censos, or “INDEC”), the wholesale price index increased 10.6% in 2005, 7.1% in 
2006, 14.4% in 2007, 8.8% in 2008 and 10.0% in 2009. We cannot assure you that in the future we will not be again required to record 
the effects of inflation in our financial statements (including those covered by the financial statements included in this annual report) 
in constant pesos. See “—Critical Accounting Policies—U.S. GAAP reconciliation” for an explanation of how the effect of inflation is 
treated under U.S. GAAP.  

Additionally, certain oil and gas disclosures are included in this annual report under the heading “Supplemental information on 

oil and gas producing activities (unaudited).”  

Segment Reporting  

We organize our business into the following segments: (i) exploration and production, which includes exploration and 
production activities, natural gas and crude oil purchases, sales of natural gas, and to a lesser extent crude oil, to third parties and 
intersegment sales of crude oil, natural gas and its byproducts and to a lesser extent electric power generation (“Exploration and 
Production”); (ii) the production, transport and marketing of crude oil that we sell to third parties and of refined products that we sell 
to third parties and other segments of our business (“Refining and Marketing”); and (iii) the production, transport and marketing of 
petrochemical products (“Chemicals”).Other activities not falling into the previously described categories are reported under a 
separate segment (“Corporate and Other”), principally including corporate administration costs and assets and construction activities.  

Sales between business segments are made at internal transfer prices established by us, which generally seek to approximate 

market prices.

Our operations are affected by a number of factors, including:  
•   the volume of crude oil, oil byproducts and natural gas we produce and sell;  
•   domestic price limitations;  
•   export restrictions and domestic supply requirements;  
•   international prices of crude oil and oil products;  
•   our capital expenditures;  
•   inflation and cost increases;  
•   domestic market demand for hydrocarbon products;  
•   operational risks;

•   taxes, including export taxes;  
•   capital controls;  
•   the Argentine peso/U.S. dollar exchange rate;  
•   dependence on the infrastructure and logistics network used to deliver our products;  
•   laws and regulations affecting our operations; and  
•   interest rates.  

Until 2008, our margins and our consolidated operating profits have trended downwards. This was principally the result of: 

production declines and increased asset depreciation, principally due to the increasing maturity of our oil and gas fields; increases in 
other operating costs, due in part to higher domestic demand and local market supply obligations (which required us to purchase 
certain hydrocarbon inputs from third parties); inflation and higher labor costs; and limitations on our ability to offset those increased 
costs due to, among other things, domestic limitations on the prices at which we could sell gas and refined products.  

Our operating income in 2009 increased by 5.0% compared with 2008, mainly as a result of higher average sales prices and 

benefits related to the Petroleum Plus Program (see “—Policy and regulatory developments in Argentina” below) due to our 
fulfillment of the requirements set forth by that program. The impact of higher sales prices and benefits of the Petroleum Plus Program 
were mostly offset by: increased depreciation of fixed assets as a result of increased assets subject to depreciation (principally 
exploration and production assets that entered into production and the acceleration of depreciation resulting from the decline in our 
proved reserves), a decline in production and higher costs mainly as a result of inflation. Notwithstanding the improvement in trend in 
2009, we cannot guarantee that such improved trend in our margins and operating income will continue in future periods.  

Our operating income in 2008 increased slightly by 0.1% compared with 2007, mainly as a result of higher average sales prices 

(despite decreases in average sales prices of certain products towards the end of the year). The impact of higher sales prices was 
mostly offset by: our continuing decline in production, increased export taxes, increased depreciation of fixed assets as a result of 
increased assets subject to depreciation (principally exploration and production assets that entered into production and the acceleration 
of depreciation resulting from the decline in our proved reserves), and higher costs as a result of the renegotiation of certain service 
contracts and inflation adjustments.  

Macroeconomic conditions  

The Argentine economy has experienced significant volatility in recent 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 was 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.  

With the enactment of the Convertibility Law in 1991, inflation declined progressively and the Argentine economy enjoyed 
seven years of growth. 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 depreciation 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 and favorable raw material pricing from 2003 through the first 

half of 2008 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 GDP growth rate decelerated sharply in 2009 (preliminary 
figures estimate that real GDP grew by 0.9% during 2009). However, according to the Argentine Central Bank, certain economic 
indicators are starting to show signs of recovery in the Argentine economy, mainly due to a recovery in exports, as well as in stock 
levels in certain sectors. According to the IMF’s April 2010 projections, the Argentine economy is expected to grow by 3.5% in 2010.  

According to the IMF, the global economy is beginning to pull out of the recession, owing mainly to cuts in interest rates by 
central banks, continued provision of ample liquidity, credit easing, public guarantees, and bank recapitalization. Nonetheless, the 
pace of recovery is expected to be slow. Several forces are holding back the recovery in Europe. Sizable fiscal and current account 
imbalances are constraining recovery in several euro area countries, with potentially negative spillover effects to the rest of Europe. In 
2010, global economic growth is projected to recover to 3.1%, although the rate of growth or, in some cases, contraction, is expected 
to vary significantly from region to region. The main policy priority remains restoring financial sector health, since bank lending 
conditions are expected to remain tight and external financing conditions constrained for a considerable time.  

65 

 
Weakened global demand since the second half of 2008 has depressed commodity prices, but in line with the signs of recovery, 

oil prices have responded strongly to signs of a demand rebound in China. This is partly attributable to Organization of Petroleum 
Exporting Countries (OPEC) members’ strict observance of lower production quotas. WTI has recently traded over U.S.$79 per 
barrel, compared to approximately U.S.$50 at the end of the first quarter of 2009, though it remains well below the average price of 
2008 (U.S.$99.67).  

In Argentina, domestic fuel prices have increased over the past two years, but have not kept pace with either increases or 
decreases in international market prices for petroleum products due to the characteristics of and regulations affecting the Argentine 
market. Nonetheless, the gap between domestic and international prices for certain products has narrowed as a result of the increase in 
domestic fuel prices as previously mentioned, and also as a result of the decline in the international prices in late 2008 and early 2009. 
See “—Differences between Argentine and international prices for hydrocarbon products.”  

In 2005, Argentina successfully completed the restructuring of a substantial portion of its bond indebtedness and canceled all of 

its debt with the IMF. Additionally, in June 2010, Argentina completed the renegotiation of approximately 66% of defaulted bonds 
that were not swapped in 2005. As a result of the 2005 and 2010 debt swaps, approximately 92.4% of the country’s bond indebtedness 
has now been restructured. Additionally, the Argentine government announced that it would repay the outstanding portion of the 
defaulted debt that was not included in the 2005 debt swap (the “Paris Club” debt). The government has passed a regulation allowing 
the withdrawal of U.S.$6.5 billion from the Argentine Central Bank reserves to support payments to multilateral lenders and 
bondholders. Currently, Standard & Poor’s (S&P) credit rating for Argentina’s sovereign debt is “B-”, with a “stable” outlook since 
October 2008, while Moody’s, which rates Argentina’s sovereign debt at “B3”, has maintained its credit watch of Argentina as 
“stable” since August 2008.  

Public finances both at national and provincial levels recorded a consolidated primary surplus of above 3% between 2004 and 

2008, according to the INDEC. In 2009, government fiscal revenues performance was worse than in previous years, mainly as a 
consequence of a slowdown in activity levels, while public expenditures increased, due to the implementation of anticyclical policies 
aimed at offsetting or reducing the contractive effects of the international crisis described above. This led to a decrease in primary 
surplus, which reached 1.36% in 2009, according to the Argentine Central Bank.  

The annual wholesale price index, according to the Argentine statistics and census agency (Instituto Nacional de Estadísticas y 

Censos, or “INDEC”), increased by 14.6% in 2007, 8.8% in 2008 and, based on preliminary data, 10.0% in 2009. According to reports 
published by the IMF, however, most private sector analysts believe that actual inflation is considerably higher than reflected in 
official data.  

Starting in the first half of 2008, conflicts in certain sectors of the Argentine economy, including blockades by agricultural 
producers in response to an export tax increase and strikes by oil workers, have affected the development and productivity of these and 
related sectors. According to the Argentine Central Bank, exports decreased 21% in 2009 as a result of lower commodity prices and a 
decrease in the exported volumes of certain agricultural products, mainly due to declines in harvest volumes as a result of a severe 
drought in parts of Argentina and reduced seeded areas. Notwithstanding the above, during the last months of 2009, exports began to 
recover, due both to an increase in prices and in exported volumes. During 2009, imports contracted even further than exports (by 
32%), due mainly to decreased imports of intermediate goods and capital assets commensurate with the slower pace of domestic 
activity. As a result, the Argentine trade balance reached an even higher surplus than in previous years. The Argentine Central Bank 
expects that in 2010 the country will complete its ninth year in a row with a trade surplus, along with a strong recovery in both exports 
and imports.  

According to INDEC, the unemployment rate corresponding to the fourth quarter of 2009 showed that 8.4% of the active 

population was unemployed, 1.2% percentage points higher than the 7.2% rate in the fourth quarter of 2008. According to the 
Argentine Central Bank, however, the foreseen increase in activity is expected to help stem the recent growth in unemployment. In 
line with the slowdown in general activity, wages increased at a slower pace than in previous years, but still outpaced price increases, 
resulting in higher purchasing capacity.  

The Argentine Central Bank reserves were U.S.$46.4 billion at the end of 2008. In 2009, reserves remained stable and relatively 

high (U.S.$48.0 billion at the end of 2009), contributing to a sustained strong external position. The exchange rate of the Argentine 
peso against the U.S dollar as of December 31, 2009 was Ps.3.80/ U.S.$1.00, reflecting peso depreciation of 10.1% compared to 
December 31, 2008.  

We cannot predict the evolution of future macroeconomic events, or the effect that they are likely to have on our business, 

financial condition and results of operations. See “Item 3. Risk Factors—Risks Relating to Argentina”.

Energy consumption in Argentina has increased significantly since 2003, driven in part by price limitations that have kept 
Argentine energy prices below international prices. Continued growth in demand and a particularly harsh winter in 2007 have led to 
fuel shortages and power outages, prompting the Argentine government to take additional measures to assure domestic supply. At the 
same time, growth in the production of certain hydrocarbon products has slowed, and in the case of crude oil production has recently 
declined, due to Argentina’s maturing oil and gas fields. As a result of this increasing demand and actions taken by the Argentine 
regulatory authorities to prioritize domestic supply, exported volumes of hydrocarbon products, especially natural gas, declined 
steadily over this period. At the same time, Argentina has increased hydrocarbon imports.  

The table below shows Argentina’s total sales, production, exports and imports of crude oil, diesel and gasoline products for the 

periods indicated.

Policy and regulatory developments in Argentina  

The Argentine oil and gas industry is currently subject to certain governmental policies and regulations that have resulted in: 

(i) domestic prices that have usually been lower than prevailing international market prices; (ii) export restrictions; (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; and (iv) increasingly higher export duties on the volumes of hydrocarbons allowed to be exported. See “Item 4. 
Information on the Company—Regulatory Framework and Relationship with the Argentine Government.” These governmental 
pricing limitations, export controls and tax policies have been implemented in an effort to satisfy increasing domestic market demand 
at prices below international market prices. 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.  

Policy and regulatory developments relating to the oil and gas industry in Argentina include, among others:  
•  Price limitations. In order to support economic growth, the Argentine government has sought to limit increases in 
hydrocarbons prices through a number of policies and measures. As a result, fluctuations in Argentina’s domestic 
hydrocarbon prices have not matched the recent increases or decreases at the pace of international and regional prices, as 
described in “—Differences between Argentine and international prices for hydrocarbon products.”  

•   Export restrictions. Since 2004, the Argentine government has prioritized domestic demand and adopted policies and 
regulations restricting the export of certain hydrocarbon products. These restrictions have impacted our export sales as 
described in “—Declining export volumes.”  

•   Export duties. Since the economic crisis in 2002, the Argentine government has imposed export taxes on certain hydrocarbon 

products. These taxes have increased substantially in the following years as international prices have surged. For a 
description of the most recent export duties on hydrocarbon exports, see “—International oil and gas prices and Argentine 
export taxes.”

•   Domestic supply requirements. The Argentine government has at times issued regulatory orders requiring producers to inject 
natural gas in excess of contractual commitments and supply other hydrocarbon products to the domestic market. As a result, 
we have had to limit our exports. In addition, we have imported diesel in order to satisfy domestic demand, which has 
increased our operating costs, as described in “—Cost of sales.”  

•   Energy Substitution Program. The Department of Federal Planning, Public Investment and Services, by Resolution 

No. 459/07 of July 12, 2007, created the “Energy Substitution Program” (Programa de Energía Total), which is designed to 
mitigate shortages of natural gas and electricity by encouraging industrial users to substitute natural gas and electricity during 
the Argentine winter with imported diesel, fuel oil and LPG subsidized by the government. Resolution No. 1451/2008 of the 
Department of Federal Planning, Public Investment and Services extended the Energy Substitution Program until 
December 31, 2009, and Rule No. 287/08 of the Sub-Secretary of Coordination and Control, issued on December 19, 2008, 
approved the general plans for implementation of the Energy Substitution Program for 2009. See “Item 4. Information on the 
Company—Regulatory Framework and Relationship with the Argentine Government—Market Regulation—Refined 
Products.” Under this program, ENARSA imports diesel, fuel oil, LPG and natural gas that we buy from ENARSA at the 
prevailing domestic prices and then sell to consumers in Argentina, mostly at similar prices. As a result, this program has the 
effect of increasing our net sales and volumes sold, but is mostly operating income-neutral since we do not earn any 
significant margin on products sold under this program. The Energy Substitution Program has recently been extended for the 
year 2010.  

•   Gas Plus. The Argentine Secretariat of Energy, by Resolution S.E. No. 24/2008 of March 13, 2008, created the “Gas Plus” 
program to encourage the production of natural gas from newly discovered reserves, new fields and tight gas, among other 
sources. Natural gas produced under the Gas Plus program will not be subject to the prices set forth in the Agreement 2007-
2011 regarding the supply of natural gas to the domestic market during the period 2007 through 2011. See “Item 4. 
Information on the Company—Regulatory Framework and Relationship with the Argentine Government—Market 
Regulation—Natural Gas.”  

•   Refining and Petroleum Plus Programs. Decree No. 2014/2008 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 operation. The Argentine Secretariat of Energy, by Resolution S.E. No. 1312/2008 of 
December 1, 2008, approved the regulation of these programs. 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 
of products within the scope of Resolution No. 394/2007 and Resolution No. 127/2008 (Annex) issued by the Department of 
Economy and Production. In order to be eligible for the benefits of both programs, companies’ plans must be approved by the 
Argentine Secretariat of Energy. Our participation in the Petroleum Plus program resulted in a positive contribution to our 
net sales in 2009.  

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 restrictions, as well as by declines in production. This shift from exports to domestic sales has 
impacted our results of operations as the prices for hydrocarbons in the domestic market have, due to price limitations, generally not 
kept pace with international and regional prices.  

The table below presents, for the periods indicated, the exported volumes of certain of our principal hydrocarbon products.

Due to the decreased export product volumes indicated above and increasing export duties, the portion of our net sales 
accounted for by exports decreased steadily between 2007 and 2009. Exports accounted for 14.3%, 20.7% and 28.9% of our 
consolidated net sales in 2009, 2008 and 2007, respectively.

The Argentine government requires companies intending to export crude oil, diesel and LPG to obtain prior authorization from 

the Argentine Secretariat of Energy by demonstrating that local demand for those products has been satisfied. Since 2005, because 
domestic diesel production has generally not been sufficient to satisfy Argentine consumption needs, exports of diesel have been 
substantially restricted.  

International oil and gas prices and Argentine export taxes  

Since the economic crisis in 2002, in order to prioritize domestic demand, the Argentine government has imposed export taxes 
on certain hydrocarbon products. These taxes have increased substantially in the following years as international prices have surged. 
For a description of these taxes, see “Item 4. Information on the Company—Regulatory Framework and Relationship with the 
Argentine Government—Taxation.” These export taxes have significantly affected the profitability of hydrocarbon exportation. They 
have also contributed to a shift away from exports and towards domestic sales, as described in “—Declining export volumes,” and 
reduced the export parity prices.  

On November 16, 2007, the Ministry of Economy and Production published Resolution 394/2007, modifying the duties on 

exports of crude oil and other crude oil derivative products. The new regime provides that when the WTI international price exceeds 
the reference price, which is fixed at U.S.$60.9/barrel, the producer shall be allowed to collect at U.S.$42/barrel, with the remainder 
being withheld by the Argentine government as an export tax. If the WTI international price is under the reference price but over 
U.S.$45/barrel, a 45% withholding rate will apply. If such price is under U.S.$45/barrel, the applicable export tax is to be determined 
by the Argentine government within a term of 90 business days. The withholding rate determined as indicated above also currently 
applies to diesel, gasoline and other crude derivative products. In addition, the calculation procedure described above also applies to 
other petroleum products and lubricants based upon different withholding rates, reference prices and prices allowed to producers. See 
“Item 4. Information on the Company—Regulatory Framework and Relationship with the Argentine Government—Market 
Regulation.”  

Under current law, pursuant to Resolution 394/2007, the maximum export sales price per barrel of oil that companies in 
Argentina could realize was U.S.$42, without considering quality price adjustments, while the average international market price per 
barrel of WTI was U.S.$61.81 in 2009.  

In the first quarter of 2008, Resolution No. 127/2008 of the Ministry of Economy and Production increased export duties 
applicable to natural gas to 100%, mandating a valuation basis for the calculation of the duty as the highest price established in any 
contract of any Argentine importer for the import of gas. Resolution No. 127/2008 provides with respect to LPG products (including 
butane, propane and blends thereof) that if the international price of the relevant LPG product, as notified daily by the Argentine 
Secretariat of Energy, is under the reference price established for such product in the Resolution (U.S.$338/m3 for propane, 
U.S.$393/m3 for butane and U.S.$363/m3 for blends of the two), the applicable export duty for such product will be 45%. If the 
international price exceeds the reference price, the producer shall be allowed to collect the maximum amount established by the 
Resolution for the relevant product (U.S.$223/m3 for propane, U.S.$271/m3 for butane and U.S.$250/m3 for blends of the two), with 
the remainder being withheld by the Argentine government as an export tax.  

See “Item 4. Information on the Company—Regulatory Framework and Relationship with the Argentine Government—Taxation.”  

We expect these export tax increases to continue to adversely affect our export net sales and margins in future financial periods, 

especially with respect to any exports of natural gas, diesel, gasoline and petrochemical products.  

Differences between Argentine and international prices for hydrocarbon products  

Prior to the recent decrease in the prices of crude oil and related products, domestic prices for our products had fallen 
significantly below international prices as a result of regulatory policies that had resulted in limitations on our ability to increase 
domestic prices sufficiently to keep pace with international market prices. The following table sets forth the average prices at which 
we sold our principal products in the domestic market (net of taxes passed through to consumers, such as value added and fuel transfer 
taxes) for the periods indicated:

in our consolidated financial statements. The average price shown for each period is the volume-weighted average price of the 
various grades of gasoline products sold by us in the domestic market during such period.  

The disparity between the prices at which hydrocarbon products have been sold in Argentina and the prevailing international 

prices for such products has been mainly due to limitations on our ability to pass increases in international prices of crude oil and 
hydrocarbon fuels and adverse exchange rate movements through to domestic prices, or to increase local prices of natural gas (in 
particular for residential customers), gasoline and diesel.  

In addition, the price at which Bolivia exports natural gas to Argentina (which is purchased by ENARSA) was approximately 

U.S.$6.16/mmBtu in December 2009, while the price at which we purchase natural gas from ENARSA was approximately 
U.S.$2.431/mmBtu in December 2009 and our average sales price for natural gas in Argentina during 2009 was approximately 
U.S.$1.79/mmBtu.  

In addition, pursuant to Resolution 599/2007 of the Argentine Secretariat of Energy dated June 14, 2007 (see “Item 4. 
Information on the Company—Regulatory Framework and Relationship with the Argentine Government—Market Regulation—
Natural gas”), the Argentine government and gas producers, including us, entered into an agreement for the supply of certain volumes 
of gas to each segment of the domestic market during the period 2007 through 2011. Under this agreement, we have supplied a total 
volume of approximately 4,700 mmcm of gas in 2009 (representing approximately 32% of our total gas volume sales for such year) to 
domestic residential and small commercial consumers at a price of approximately Ps.0.67/mmBtu for that period.  

Relative maturity of our oil and gas assets  

Argentina’s oil and gas fields are mature and, as a result, our reserves and production are declining as reserves are depleted. 
Because we mainly have concessions for mature oil and gas fields that are undergoing natural production declines, it is difficult to 
replace our proved reserves from other categories of reserves. In 2009, our estimated proved oil reserves and oil production, without 
considering NGL, declined by 4.9% and 5.6%, respectively, over the preceding year, while our estimated proved gas reserves and gas 
production declined by 13.8% and 12.2%, respectively, over the same period. In an effort to maintain our high refinery utilization 
rates and because of regulatory requirements to supply certain hydrocarbon products to the domestic market, we purchased crude oil 
and natural gas from third parties. We expect our oil and gas proved reserves and production rates to continue their decline. See “Item 
4. Information on the Company—Exploration and Production—Oil and Gas Reserves” for more information on our proved reserves.  

We continue pursuing an initiative, which encompasses comprehensive reviews of our oil and gas fields to identify opportunities 

in light of new technologies and to design novel strategies to rejuvenate old fields and optimize the development of new fields in 
Argentine basins. Many of our fields have similar characteristics to mature fields in other regions of the world that have achieved 
substantially higher recovery factors through the application of new technologies, similar to the ones we are currently evaluating. 
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.  

We have budgeted approximately U.S.$2.1 billion in investments and capital expenditures for 2010, a significant portion of 

which will be dedicated to our exploration and production activities. During the period 2010-2012, we expect to make capital 
expenditures of around U.S.$7.2 billion, principally related to our exploration and production projects, including some to increase 
recovery rates in our fields.  

Cost of sales  

Our cost of sales accounted for 67.5%, 68.9% and 65.3% of our consolidated net sales in 2009, 2008 and 2007, respectively. 

Our cost of sales increased between 2007 and 2009, mainly as a result of: increased purchases of crude oil from third parties, driven 
by our efforts to maintain our high refinery utilization rates in light of our declining production; increased purchases of natural gas and 
diesel from third parties; higher labor costs; higher costs related to the renegotiation of certain service contracts; and inflation. Due to 
prevailing Argentine price limitations, we were unable to pass some of these cost increases to our customers in the form of higher 
hydrocarbon product prices.  

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, the use of this fuel has diversified, generating an increase in its long-term demand throughout the year. However, sales of 
natural gas are still typically much higher in the winter to the residential sector of the Argentine domestic market, the prices for which 
are significantly lower than other sectors of the Argentine market.

Critical Accounting Policies  

Our accounting policies are described in Notes 1 and 2 to the Audited Consolidated Financial Statements. Argentine GAAP 
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 to be most critical in understanding the judgments that are involved in preparing our financial 
statements and the uncertainties that could impact our results of operations, financial condition and cash flows.  

Oil and gas reserves  

The estimation of oil and gas reserves is an integral part of the decision-making process about oil and gas assets, such as 
whether development should proceed or enhanced recovery methods should be implemented. As further explained below, oil and gas 
reserve quantities are used for calculating depreciation of the related oil and gas assets using the unit-of-production rates and also for 
evaluating the impairment of our investments in upstream assets.  

At YPF, all the assumptions made and the basis for the technical calculations used in the estimates regarding oil and gas proved 

reserves are based on the guides and definitions established by Rule 4-10(a) of Regulation S-X promulgated by the SEC.  

See “Item 4. Information on the Company—Exploration and Production—Oil and Gas Reserves” for a detailed discussion on 

reserves estimates internal control and audits.  

We follow the “successful efforts” method of accounting for our oil and gas exploration and production operations. 

Accordingly, exploratory costs, excluding the costs of exploratory wells, have been charged to expense as incurred. Costs of drilling 
exploratory wells, including stratigraphic test wells, have been capitalized pending determination as to whether the wells have found 
proved reserves that justify commercial development. If such reserves were not found, the mentioned costs are charged to expenses. 
Occasionally, however, an exploratory well may be determined to have found oil and gas reserves, but classification of those reserves 
as proved cannot be made when drilling is completed. In those cases, the cost of drilling the exploratory well continues to be 
capitalized if the well has found a sufficient quantity of reserves to justify its completion as a producing well and the enterprise is 
making sufficient progress assessing the reserves and 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 expenses.  

Intangible 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 related to producing activities, including tangible and intangible costs, have been depreciated by field on 
the unit-of-production basis by applying the ratio of produced oil and gas to estimated recoverable proved and developed oil and gas 
reserves.  

The capitalized costs related to acquisitions of properties with proved reserves have been depreciated by field on the unit-of-

production basis by applying the ratio of produced oil and gas to proved oil and gas reserves.  

Revisions of crude oil and natural gas proved reserves are considered prospectively in calculating depreciation.  

Capitalized costs related to unproved properties are reviewed periodically by management to ensure that their carrying value 

does not exceed their estimated recoverable value.  

Impairment of long-lived assets  

We assess the recoverability of our held-for-use assets on a business segment basis for Argentine GAAP purposes. With respect 
to operations that are held as pending sale or disposal, our policy is to record these assets at amounts that do not exceed net realizable 
value.  

For Argentine GAAP, held-for-use properties, grouped by business segment, are reviewed for impairment whenever events or 

changes in circumstances indicate that the carrying amounts may not be recoverable. An asset would be impaired if the discounted 
cash flows were less than its carrying value.  

The impairment of oil and gas producing properties is calculated as the difference between the market value or, if appropriate, 

the discounted estimated future cash flows from its proved reserves and unproved reserves, adjusted for risks related to such reserves, 
owned at the year end with the net book value of the assets relating thereto. Expected future cash flows from the sale or production of 
reserves are calculated considering crude oil prices based on a combination of market forward quotes and standard long-term 
projections. The discounted values of cash flows are determined using a reasonable and supportable discount rate based on standard 
WACC-CAPM (weighted average cost of capital—capital asset pricing model) assumptions including, if appropriate, a risk premium 
related to this type of asset. The estimated cash flows are based on future levels of production, the future commodity prices, lifting and 
development costs, estimates of future expenditures necessary with respect to oil and gas reserves, field decline rates, market demand 
and supply, economic regulatory conditions and other factors.  

71 

 
The impairment of assets corresponding to our Refining and Marketing and Chemicals business segments is calculated as the 

difference between the discounted estimated future cash flows from the use of those assets and the net book value of the assets related 
thereto. The discounted values of cash flows are determined using a discount rate we believe to be reasonable and supportable based 
on standard WACC-CAPM (weighted average cost of capital—capital asset pricing model) assumptions including, if appropriate, a 
risk premium related to the type of asset. The estimated cash flows are based on future levels of production, the future estimated prices 
of our products and costs, other estimates of future expenditures, estimated useful life of the respective asset, market demand and 
supply, economic regulatory conditions and other factors for each business segment.  

Charges for impairment may be recognized in our results from time to time as a result of, among other factors, adverse changes 

in the recoverable reserves from oil and natural gas fields, and changes in economic regulatory conditions. If proved reserves 
estimates were revised downward, net income could be negatively affected by higher impairment charges on the property’s book 
value.  

Therefore, our management must make reasonable and supportable assumptions and estimates with respect to: (i) the market 
value of reserves, (ii) oil fields’ production profiles and future production of refined and chemical products, (iii) future investments, 
taxes and costs, (iv) risk factors for unproved reserves which are measured based on the profile and potential of each specific 
exploration and production asset, (v) future capital expenditures and useful life for properties corresponding to our Refining and 
Marketing and Chemicals business segments, and (vi) future prices, among other factors. As such, any change in the variables used to 
prepare such assumptions and estimates may have a significant effect on the impairment tests.  

Impact of oil and gas reserves and prices on testing for impairment  

Proved oil and gas properties held and used by us are reviewed for impairment whenever events or circumstances indicate that 
the carrying amounts may not be recoverable. Impairments are measured by the amount by which the carrying value exceeds its fair 
value.  

We perform asset valuation analyses on an ongoing basis as a part of our asset management program. In general, we do not view 

temporarily low oil prices as a triggering event for conducting the impairment tests. Accordingly, any impairment tests that we 
perform make use of our long-term price assumptions for the crude oil and natural gas markets and petroleum products.  

Depreciation of oil and gas producing properties  

Volumes produced and asset costs are known, while proved reserves have a high probability of recoverability and are based on 

estimates that are subject to some variability. The impact of changes in estimated proved reserves is treated prospectively by 
depreciating the remaining book value of the assets over the future expected production, affecting the following year’s net income. In 
2009, 2008 and 2007 we recorded depreciation of fixed assets associated with hydrocarbon reserves amounting to Ps.4,019 million, 
Ps.4,058 million and Ps.3,564 million, respectively.  

Asset retirement obligations  

Future costs related to hydrocarbon wells abandonment obligations are capitalized 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 same estimated 
value of the discounted payable amounts. Future estimated retirement obligations and removal costs are based on management’s best 
estimate of the time that the event will occur and the assertion of costs to be incurred upon the retirement or removal of the asset. 
Asset removal technologies and costs, as well as political, environmental, safety and other requirements and public expectations, are 
frequently changing. Consequently, the timing and future cost of dismantling and abandonment are subject to significant modification. 
As such, any change in variables used to prepare such assumptions and estimates can have, as a consequence, a significant effect on 
the liability and the related capitalized asset and future charges related to the retirement obligations. Future obligations are reviewed 
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 the wells in operation and/or not abandoned and 
the complexity with respect to different geographic areas where the wells are located, the current costs incurred in plugging are 
extrapolated to the wells pending abandonment. Management believes that current plugging costs incurred are the best source of 
information at the end of each fiscal year to estimate asset retirement obligations for wells.  

Environmental liabilities, litigation and other contingencies  

Environmental liabilities are recorded when environmental assessments and/or remediation are probable, material and can be 
reasonably estimated. Such estimates are based on either detailed feasibility studies of remediation approach and cost for individual 
sites, or on our estimate of costs to be incurred based on historical experience and available information for the stage of assessment 
and/or remediation of each site. As additional information becomes available regarding each site or as environmental standards 
change, we revise our estimate of costs to be incurred in environmental assessment and/or remediation.  

72 

 
Reserves are established to cover litigation and other contingencies, including counsel fees and judicial expenses, which are 
probable and can be reasonably estimated. The final costs arising from litigation and other contingencies may vary from our estimates 
due to changes in laws or differing interpretations of laws, the issuance of court decisions or other opinions and final assessments of 
the amount of claims. Changes in the facts or circumstances related to these types of contingencies, as well as the future outcome of 
these disputes, can have, as a consequence, a significant effect on the reserves for litigation and other contingencies recorded.  

U.S. GAAP reconciliation  

The recurrent difference between our net income under Argentine GAAP and our net income under U.S. GAAP for the years 

ended December 31, 2009, 2008 and 2007 is primarily due to the remeasurement into functional currency and translation into 
reporting currency, the elimination of the inflation adjustment into Argentine constant pesos, the effects of the reorganization of 
entities under common control, the impairment of long-lived assets, capitalization of financial expenses, accounting for assets 
retirement obligations, proportional consolidation of investments in jointly controlled companies, and the consolidation of variable 
interest entities.  

Under Argentine GAAP, financial statements are presented in constant Argentine pesos (“reporting currency”). Foreign 

currency transactions are recorded in Argentine pesos by applying to the foreign currency amount the exchange rate between the 
reporting and the foreign currency at the date of the transaction. Exchange rate differences arising on monetary items in foreign 
currency are recognized in the income statement of the period.  

Under U.S. GAAP, a definition of the functional currency is required which may differ from the reporting currency. 
Management has determined, for us and certain of our subsidiaries and investees, the U.S. dollar to be the functional currency in 
accordance with ASC 830. Therefore, we have re-measured into U.S. dollars the Audited Consolidated Financial Statements as of 
December 31, 2009, 2008 and 2007, in each case prepared in accordance with Argentine GAAP by applying the procedures specified 
in ASC 830. The objective of the re-measurement process is to produce the same results that would have been reported if the 
accounting records had been kept in the functional currency. Accordingly, monetary assets and liabilities are re-measured at the 
balance sheet date (current) exchange rate. Amounts carried at prices in past transactions are re-measured at the exchange rates in 
effect when the transactions occurred. Revenues and expenses are re-measured on a monthly basis at the average rates of exchange in 
effect during the period, except for consumption of non-monetary assets, which are re-measured at the rates of exchange in effect 
when the respective assets were acquired. Translation gains and losses on monetary assets and liabilities arising from the re-
measurement are included in the determination of net income (loss) in the period such gains and losses arise. Furthermore, for certain 
of our subsidiaries and investees, we have determined the Argentine peso as the functional currency. Translation adjustments resulting 
from the process of translating the financial statements of subsidiaries that use peso as their functional currency into YPF’s functional 
currency (U.S. dollars) are accounted for in other comprehensive income (“OCI”), as a component of shareholders’ equity.  

The amounts obtained from the re-measurement process referred to above are translated into Argentine pesos under the 

provisions of ASC 830. Assets and liabilities are translated at the current selling exchange rate of Ps.3.80, Ps.3.45 and Ps.3.15 to 
U.S.$1.00, as of December 31, 2009, 2008 and 2007, respectively. Revenues, expenses, gains and losses reported in the income 
statement are translated at the exchange rate existing at the time of each transaction or, if appropriate, at the weighted average of the 
exchange rates during the period. Translation effects of exchange rate changes are included as a cumulative translation adjustment in 
shareholders’ equity. For the years ended December 31, 2009, 2008 and 2007, the re-measurement into functional currency and the 
translation into reporting currency decreased net income determined according to Argentine GAAP by Ps.1,478 million, Ps.1,230 
million and Ps.1,513 million, respectively.  

Under Argentine GAAP, we have proportionally consolidated, net of intercompany transactions, assets, liabilities, net sales, cost 

and expenses of investees in which joint control is held. Under U.S. GAAP, these investees are accounted for by the equity method. 
The proportional consolidation mentioned above generated an increase of Ps.820 million, Ps.648 million and Ps.486 million and in 
total assets and total liabilities as of December 31, 2009, 2008 and 2007, respectively, and an increase of Ps.1,433 million, Ps.1,770 
million and Ps.1,350 million in net sales and Ps.551 million, Ps.681 million and Ps.690 million in operating income for the years 
ended December 31, 2009, 2008 and 2007, respectively.  

Under Argentine GAAP, in order to perform the recoverability test, long-lived assets are grouped with other assets at business 

segment level, and they would be impaired if the discounted cash flows, considered at business segment level, were less than its 
carrying value. With respect to assets that were held pending sale or disposal, our policy was to record these assets on an individual 
basis at amounts that did not exceed net realizable value.  

Under U.S. GAAP, until December 31, 2008, we performed the impairment test on proved oil and gas properties on an 

individual field basis. From January 2009, we have reassessed our proved oil and gas properties’ grouping, as a consequence of certain 
regulatory developments that have been implemented in Argentina during recent periods that have also affected our operations, as 
described in “Item 4. Information on the Company—Regulatory Framework and Relationship with the Argentine Government.” As a 
consequence of this reassessment, from January 1, 2009, oil properties are grouped into an unique cash generating unit and gas 

73 

 
properties are grouped by basin, considering logistics restrictions. Impairment charges recorded through December 31, 2008, have not 
been reversed, and the modification in the long-lived asset grouping has therefore not had any effect on our results of operations for 
the period ended December 31, 2009. Other long-lived assets are aggregated, so that the discrete cash flows produced by each group 
of assets may be separately analyzed. Each asset is tested following the guidelines of ASC 360, by comparing the net book value of 
such an asset with the expected undiscounted cash flow. Impairment losses are measured as the amount by which the carrying amount 
of the assets exceeds the fair value of the assets. When market values are not available, we estimate them using the expected future 
cash flows discounted at a rate commensurate with the risks associated with the recovery of the assets. There were no impairment 
charges under U.S. GAAP for the fiscal year ended December 31, 2009. The accumulated adjustments under U.S. GAAP of the 
impairment provisions as of December 31, 2009, 2008 and 2007 were Ps.498 million, Ps.613 million and Ps.554 million, respectively, 
mainly corresponding to our Exploration and Production segment. Additional impairment charges under U.S. GAAP amounted to 
Ps.124 million and Ps.180 million for the years ended December 31, 2008 and 2007, respectively. The impairment recorded in 2008 
and 2007 was mainly the result of a decrease in oil and gas reserves affecting certain long-lived assets of our Exploration and 
Production business segment. See “Item 4. Information on the Company—Exploration and Production.” The adjusted basis after 
impairment resulted in lower depreciation under U.S. GAAP by Ps. 173 million, Ps.119 million and Ps.132 million for the years ended 
December 31, 2009, 2008 and 2007, respectively.  

Under U.S. GAAP, only interest expense on qualifying assets must be capitalized, regardless of the asset’s construction period. 
Under Argentine GAAP, for those assets that necessarily take a substantial period of time to get ready for its intended use, borrowing 
costs (including interest and exchange differences) should be capitalized. Accordingly, borrowing costs for those assets whose 
construction period exceeds one year have been capitalized, provided that such capitalization does not exceed the amount of financial 
expense recorded in that period or year.  

Under U.S. GAAP, ASC 410 addresses financial accounting and reporting for obligations associated with the retirement of 
tangible long-lived assets and the associated asset retirement cost. The standard applies to the legal obligation associated with the 
retirement of long-lived assets that results from the acquisition, construction, development and normal use of the asset. ASC 410 
requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred, if a 
reasonable estimate of fair value can be made. The asset retirement obligations liability is built up in cash flow layers, with each layer 
being discounted using the discount rate as of the date that the layer was created. Remeasurement of the entire obligation using current 
discount rates is not permitted. Each cash flow layer is added to the carrying amount of the associated asset. This additional carrying 
amount is then depreciated over the life of the asset. The liability is increased due to the passage of time based on the time value of 
money (“accretion expense”) until the obligation is settled. Argentine GAAP is similar to ASC 410, except for a change in the 
discount rate is treated as a change in estimates, so the entire liability must be recalculated using the current discount rate, being the 
change added or reduced from the related asset.  

Under U.S. GAAP, results on sales of noncurrent assets to entities under common control (that is, in our case, to companies that 
comprise Repsol YPF) and the corresponding accounts receivable are eliminated and related accounts receivables are considered as a 
capital (dividend) transaction. Under Argentine GAAP, these results and the corresponding accounts receivable are recognized in the 
statement of income and the balance sheet, respectively.  

YPF Holdings has a non-contributory defined-benefit pension plan and postretirement and postemployment benefits. On 
December 31, 2006, under U.S. GAAP, the company adopted the Statement of Financial Accounting Standards (“SFAS”) No. 158 
(currently included in ASC 715). Under provisions of ASC 715, the company fully recognized the underfunded status of defined-
benefit pension and postretirement plans as a liability in the financial statements, reducing the company’s shareholders’ equity through 
the accumulated OCI account. Unrecognized gains and losses are recognized in the income statement during the expected average 
remaining working lives of the employees participating in the plans and the life expectancy of retired employees. Under Argentine 
GAAP, as of December 31, 2009, the actuarial losses and gains are charged to the “Other income/(expense), net” account of the 
statement of income. As of December 31, 2008 and 2007, the unrecognized actuarial losses and gains generated since December 31, 
2003 were disclosed net of the present value of the obligation and were recognized in the statement of income during the expected 
average remaining service period of the employees participating in the plans and the life expectancy of the retired employees. The 
effect on net income related to the change in the accounting recognition criteria for losses and gains due to changes in actuarial 
assumptions for the years ended December 31, 2008 and 2007, is not material. For a more detailed discussion of the most significant 
differences between Argentine GAAP and U.S. GAAP, please refer to Notes 13, 14 and 15 to the Audited Consolidated Financial 
Statements.  

Principal Income Statement Line Items  

The following is a brief description of the principal line items of our income statement.  

74 

 
  
Net sales  

Net sales include primarily our consolidated sales of unrefined and refined fuel and chemical products net of the payment of 
applicable fuel transfer taxes, turnover taxes and custom duties on exports. 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 in determining net sales. See “Item 4. Information on the Company—
Exploration and Production—Oil and gas production, production prices and production costs” and Note 2 (f) to the Audited 
Consolidated Financial Statements.

Other income/(expense), net  

Other income/(expense), net principally include credits and charges for pending lawsuits and other claims, provisions for 

environmental remediation and provisions for defined benefit pension plans and other post-retirement benefits.  

Finance income/(expense), net and holding (losses)/gains  

Finance income/(expense), net and holding (losses)/gains consist of the net of gains and losses on interest paid and interest 

earned, currency exchange differences and the periodic revaluation of inventories.  

Taxes  

The statutory corporate income tax rate in Argentina was 35% during each of the periods presented in this annual report. Our 
effective tax rates for the periods discussed in this annual report exceed the Argentine corporate income tax rate mainly due to the 
non-deductibility of the amortization of the effect of inflation indexation on fixed assets, along with other minor effects. See Note 3(j) 
to the Audited Consolidated Financial Statements.

Net sales  
Net sales in 2009 were Ps.34,320 million, representing a 1.6% decrease compared to Ps.34,875 million in 2008. This decrease 
was primarily attributable to a decline in the average prices and volumes of exported products, resulting from the negative economic 
trend which affected global trading since the second half of 2008, as well as the decrease in the volume of diesel sold in the domestic 
market due to lower demand during 2009 as a result of the economic slowdown. Commodity prices in general were strongly affected 
in 2009, and the average price per barrel of WTI decreased by approximately 38% compared to 2008. As a result, the price of certain 
products sold in the domestic market, which track international prices (such as LPG, aviation fuel, and certain petrochemicals), also 
decreased. See “—Results of operations by business segment for the years ended December 31, 2009, 2008 and 2007—Refining and 
Marketing”. In addition, demand for fertilizers in the domestic market decreased, particularly in the first half of 2009. These decreases 
were mostly offset by increases in the average domestic prices of diesel and gasoline, the higher volume of gasoline sold in the 
domestic market and income recorded under the Petroleum Plus Program, resulting from the efforts we have made within the scope of 
the program and which allowed us to maintain our commitment towards the fulfillment of domestic demand.  

Net sales in 2008 were Ps.34,875 million, representing a 19.8% increase compared to Ps.29,104 million in 2007. This increase 

was primarily attributable to increases in the average domestic prices of diesel (24.7%) and gasoline (27.8%), as well as a 33% 
increase in the average price of natural gas sold in the domestic market. The increase in volume of gasoline sold in the domestic 
market (13.5%) also contributed to this increase. In addition, there were significant price increases in other products, such as jet fuel 
and aviation gasoline, both in the domestic and export markets. As a result, our domestic sales increased 33.5% to Ps.27,647 million in 
2008 from Ps.20,704 million in 2007. These increases were partially offset by higher export taxes attributable to the application of 
Resolution 394/2007, which resulted in an increase, year over year, of approximately Ps.2,470 million in export taxes applicable to 
petrochemical and refined products. Export net sales declined by 13.9% to Ps.7,228 million in 2008 from Ps.8,400 million in 2007, as 
a result of higher export taxes and declines in the exported volumes of natural gas, gasoline and crude oil (which decreased 57%, 31% 
and 24%, respectively), partially offset by an increase in international gasoline and diesel prices. Our export sales in both periods were 
made mainly to the United States and Brazil.  

For further information on our net sales for the periods discussed above, see “—Results of operations by business segment for 

the years ended December 31, 2009, 2008 and 2007.”  

Cost of sales  
Cost of sales in 2009 was Ps.23,177 million, compared to Ps.24,013 million in 2008, representing a 3.5% decrease, which was 

mainly attributable to a decrease in the volume of products purchased from third parties, particularly diesel and fertilizers, in line with 
the decreased demand for these products, and crude oil. Strikes in the Southern region of Argentina in the second quarter of 2008 
adversely affected our oil production and our margins in that year as a result of the higher volume of products purchased from third 
parties, whereas strikes in the third quarter of 2009 had a smaller impact on our margins.  

Cost of sales in 2008 was Ps.24,013 million, compared to Ps.19,000 million in 2007, representing a 26.4% increase, which was 

mainly attributable to a 21% increase in the volume of crude oil purchased from third parties, driven by our efforts to maintain our 
high refinery utilization rates notwithstanding our declining production. Increased volumes of crude oil purchases from third parties 
adversely affect our margins because we lose the margin earned on our internal exploration and production activities. In addition, 
depreciation of fixed assets increased 15.4%, mainly as a result of increased asset values attributable to (i) increased assets (principally 
related to our Exploration and Production business segment) subject to depreciation in 2008, and (ii) higher capitalized well 
abandonment obligations during the first semester of 2008, according to the new estimates performed as of that time based on new 
information concerning future costs associated with those activities, which began to be depreciated in the second half of 2008 based 
on the unit of production method. Salaries and social security taxes, maintenance costs, contract services and certain other production 
costs also increased significantly, driven mainly by inflation and the renegotiation of certain labor and service contracts.  

Selling expenses  
Our selling expenses were Ps.2,490 million in 2009, Ps.2,460 million in 2008 and Ps.2,120 million in 2007, representing an 

increase of 1.2% from 2008 to 2009 and an increase of 16.0% from 2007 to 2008. These higher costs in 2009 were a result of 
increases in operation services and other service contracts, including the refurbishing of our service stations to fit them for the sale of 
our new low-sulfur diesel (Euro Diesel), preservation, repair and maintenance and, to a lesser extent, rental of real estate and 
equipment. The increase in costs in 2008 was due mainly to the increase in the volume of gasoline sold in the domestic market, which 
was sold mainly through service stations and resulted in higher logistics costs for us, the increase in our net sales, which determines 
the amount of transaction taxes we pay in connection with them (a transaction tax of 0.6% or, in certain instances, a different rate is 
levied on debits and credits in bank accounts).  

77 

 
Operating income  
Operating income in 2009 was Ps.6,999 million, compared to Ps.6,665 million in 2008, representing a 5% increase, due to the 

factors described above.  

Operating income in 2008 was Ps.6,665 million, compared to Ps.6,657 million in 2007, representing a slight increase of 0.1%.  

Our operating margins (operating income divided by net sales) were 20.4%, 19.1% and 22.9% in 2009, 2008 and 2007, 
respectively. Increased volumes of crude oil purchases in 2008 and 2007 adversely affected our margins because we lost the margin 
earned on our internal exploration and production activities.  

Other income/(expense), net  
Other income, net amounted to Ps.159 million in 2009 compared to other expenses, net of Ps.376 million in 2008, due mainly 
to: (i) lower expenses related to environmental obligations of our wholly controlled subsidiary YPF Holdings, which in 2008 entered 
into an agreement for the remediation of a portion of the Passaic River, as mentioned in Note 10 (a) to our Audited Consolidated 
Financial Statements; (ii) recoveries related to certain claims, as a result of their reassessment in light of new developments in our 
legal proceedings; (iii) income derived from insurance coverage in compensation for certain damages that we suffered in our facilities, 
and; (iv) certain recoveries from insurance claims related to Profertil, our jointly controlled entity. See Note 3(i) to our Audited 
Consolidated Financial Statements.  

Other expenses, net decreased 14.4% to Ps.376 million in 2008 from Ps.439 million in 2007, mainly as a result of decreased 

provisions for lawsuits, partially offset by increased environmental obligations, due mainly to new information which became 
available during 2008. See Note 3(i) to our Audited Consolidated Financial Statements.  

Financial income/(expense), net and holding gains/(losses)  
In 2009, financial expense, net and holding losses, increased to Ps.1,242 million, from Ps.174 million in 2008. The increase was 

mainly due to higher interest expense from loans attributable to our increased indebtedness and a slight decline in the value of our 
inventories in 2009 (whereas the value of our inventories increased in 2008). In addition, we suffered from higher net negative 
exchange rate differences resulting from the depreciation of the Argentine peso against the U.S. dollar, as our outstanding liabilities 
denominated in U.S. dollars exceed our assets denominated in U.S. dollars.  

In 2008, financial expense, net and holding gains was Ps.174 million, compared to financial income, net and holding gains of 

Ps.518 million in 2007. These negative results were attributable mainly to lower interest earnings resulting from our decreased 
financial investments, the increase of interest expense from loans attributable to our increased indebtedness in 2008 compared to 2007, 
and negative exchange rate differences due to the depreciation of the peso against the US dollar.  

Taxes  
Income tax expense in 2009 decreased 5.9% to Ps.2,408 million from Ps.2,558 million in 2008. The effective income tax rates 

for 2009 and 2008 were 40.9% and 41.3%, respectively, compared to the statutory income tax rate of 35%.  

Income tax expense in 2008 decreased 7.3% to Ps.2,558 million from Ps.2,758 million in 2007. The effective income tax rates 

for 2008 and 2007 were 41.3% and 40.3%, respectively, compared to the statutory income tax rate of 35%.  

Our effective tax rates exceed the Argentine corporate income tax rate due to the negative results from YPF Holdings, which did 

not give rise to a tax credit or deduction under Argentine law because YPF Holdings is a foreign company. In addition, the deferred 
tax assets generated by YPF Holdings’ losses have been fully provisioned because there is no expectation that YPF Holdings will be 
able to make use of any such tax benefits in future periods. The non-deductibility of the amortization of the effect of inflation 
indexation on fixed assets, which is not deductible from income tax under prevailing Argentine tax legislation, also contributed to our 
higher effective tax rates. See Note 3(j) to the Audited Consolidated Financial Statements.  

Net income  
Net income for 2009 was Ps.3,486 million, compared to Ps.3,640 million in 2008, a decrease of 4.2%. This decrease is mainly 

attributable to the increase in financial expense described above.  

Net income for 2008 was Ps.3,640 million, compared to Ps.4,086 million in 2007, a decrease of 10.9%. This decrease is mainly 

attributable to the decline in the financial income described above.

(1)  Net sales are net to us after payment of a fuel transfer tax, turnover tax and custom duties on exports. 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 in determining net sales. See “Item 4. 
Information on the Company—Exploration and Production—Oil and gas production, production prices and production costs” 
and Note 2 (f) to the Audited Consolidated Financial Statements.  
Includes exploration and production operations in Argentina and the United States.  
Intersegment sales of crude oil to Refining and Marketing are recorded at transfer prices that reflect our estimates of Argentine

Exploration and Production  
Exploration and Production net sales in 2009 were Ps.19,981 million, representing a 13.4% increase from Ps.17,618 million in 

2008. Intersegment net sales (substantially all of which relate to intersegment sales of crude oil) increased by Ps.1,810 million in 2009, 
mainly as a result of a 19% increase in the average intersegment price in pesos of a barrel of oil (1% increase in U.S. dollars), which 
was partially offset by a 1.7% decrease in the volumes transferred. Net sales in 2009 were also strengthened by the income recorded 
pursuant to the Petroleum Plus Program and a 7.0% increase in the domestic price of natural gas mainly attributable to price increases 
for gas sold to industrial customers and thermal power plants in the domestic market during 2009, which were partially offset by a 
decrease in the price of natural gas sold to our jointly controlled company, Mega, which is set according to international parameters 
and therefore decreased in line with the WTI price. Natural gas exported volumes remained low in 2009 due to the restrictions we are 
subject to. Export taxes remained relatively stable in 2009 compared with 2008.  

Exploration and Production operating income increased 62% to Ps.5,379 million in 2009 from Ps.3,315 million in 2008, as a 

result of the increase in inter-segment crude oil prices, and the income recorded pursuant to the Petroleum Plus Program, as explained 
above. This was partially offset by a 2.1% increase in segment operating expenses, which was mainly due to increases in the prices of 
service contracts resulting from general costs increase, and an increase in royalties paid by Ps.121 million, due to the higher value, 
expressed in pesos at the wellhead (used as the basis for calculation of such royalties), of hydrocarbons produced (mainly as a result of 
the 10.1% peso depreciation against the U.S. dollar compared to December 31, 2008).  

Average oil production during 2009 decreased 3.5% to 302 thousand barrels per day from 313 thousand barrels per day in 2008. 

Natural gas production in 2009 decreased 11.9% to 1,470 mmcf/d from 1,658 mmcf/d in 2008. These declines were mainly 
attributable to the natural decline in the production curve resulting from the continuing overall maturity of our fields, and the decline 
in natural gas demand from industrial customers and thermal power plants.  

Exploration and Production net sales in 2008 were Ps.17,618 million, representing a 2.5% decrease from Ps.18,068 million in 

2007. Intersegment sales to Refining and Marketing, substantially all of which were crude oil sales, decreased Ps.1,393 million in 
2008. This variation was due to a 6.3% decrease in the volume of crude oil sales that resulted mainly from a decline in our production 
attributable to the strikes that affected our operations in the Southern region of Argentina, and the increasing maturity of our fields, as 
well as a 6% decrease in intersegment oil prices in 2008 compared to 2007. This decrease in intersegment oil prices was due to our 
consideration of the effect of Resolution 394/2007, which among other things, established certain reference prices for crude oil. These 
effects were partially offset by a 33.3% increase in the average price of natural gas sold in the domestic market, due mainly to 
increases in the price of natural gas sold to industrial customers and thermal power plants, during 2008.  

Exploration and Production operating income declined 41.6% to Ps.3,315 million in 2008 from Ps.5,679 million in 2007, due to 

the above-mentioned decline in crude oil sales volumes and to higher operating expenses. Segment operating expenses increased 
15.4% due to significant increases in contract works and services, driven mainly by cost increases in service contracts due to inflation 
and the high oil prices that prevailed during a significant part of the year. Additionally, we recorded a Ps.495 million, or 13.7%, 
increase in depreciation of fixed assets mainly due to the increase in assets subject to depreciation resulting mainly from higher capital 
expenditures, as well as increased well abandonment obligations.  

Average oil production during 2008 decreased 4.9% to 313 thousand barrels per day from 329 thousand barrels per day in 2007. 

Natural gas production in 2008 decreased 4.7% to 1,658 mmcf/d from 1,740 mmcf/d in 2007. These declines were attributable to the 
natural decline in the production curve resulting from the continuing overall maturity of our fields and the strikes that took place in the 
Southern region of Argentina during the first half of 2008.  

Refining and Marketing  
Refining and Marketing net sales in 2009 were Ps.27,562 million, 1.6% lower than the Ps.28,017 million in net sales recorded in 

2008. This decrease was mainly attributable to the sharp decreases in international prices for substantially all of our exported refined 
products, a decrease in the volumes of gasoline sold by us in the export market (11.7%), and a decline in the volumes of diesel sold in 
the domestic market (6.7%). These decreases were partially offset by an increase in the average domestic prices of diesel and gasoline 
(of 17.7% and 23.6%, respectively), as well as a 10.7% increase in the volume of gasoline sold domestically. Notwithstanding the 
increase in the average domestic prices of diesel and gasoline, domestic prices for our products remained below average international 
prices. In addition, the domestic prices of certain refined products that tend to track international prices, such as aviation fuel and 
LPG, decreased in 2009.  

Refining and Marketing operating profit decreased 38.6% to Ps.1,896 million in 2009 from Ps.3,089 million in 2008. This 
decrease was mainly due to the aforementioned decline in international prices. In addition, purchases of crude oil, which account for 
approximately 90% of the segment’s operating costs, were made at a price which was on average 19% higher in Argentine pesos than 
the previous year (although it was less than 1% higher when measured in U.S. dollars). Further, refining costs (excluding crude oil 
purchase and transport costs) increased by approximately 17%, mainly due to the higher costs of energy and increases in operation 
services and service contract costs, as well as higher depreciation costs arising from an increase in assets that commenced operations. 
Refining cost per barrel, which we calculate as the segment’s production costs for the period less crude oil purchase costs, divided by 
the number of barrels produced during the period, was Ps.14.8 in 2009, compared to Ps.12.7 in 2008.  

80 

 
Refinery output in 2009, including 50% of Refinor’s output (we own 50% of Refinor), reached 310 thousand barrels per day, 

representing a 5.4% decrease compared to 328 thousand barrels per day processed in 2008. The decrease is mainly a result of planned 
overhauls in our refineries, as well as external factors which affected our operations such as strikes related to the transport services 
used to receive crude oil supplies.  

Refining and Marketing net sales in 2008 were Ps.28,017 million, 15.4% higher than the Ps.24,278 million in net sales recorded 
in 2007. This increase was mainly attributable to increases in average prices of diesel and gasoline sold in the domestic market (24.7% 
and 27.8%, respectively), the segment’s two principal products, as well as a 13.5% increase in the volume of gasoline sold in the 
domestic market. Notwithstanding the aforementioned increases, average prices of domestic sales remained lower than international 
prices. Diesel volumes sold in the domestic market decreased slightly (0.8%). Our increased domestic sales were partially offset by 
lower volumes of exported gasoline (which decreased by 30.9%).  

Refining and Marketing operating profit increased to Ps.3,089 million in 2008, from Ps.1,234 million in 2007. This increase was 
due to the above-mentioned increase in the domestic price of diesel and increases in domestic prices and volumes of gasoline sales. A 
6% decrease in the average price paid for crude oil to our Exploration and Production business segment was the result of considering 
the effect of Resolution 394/2007, which established certain reference prices for crude oil, in calculating our intersegment oil prices. 
Purchases of crude oil accounted for approximately 90% of the segment’s operating costs. In addition there was a 17% increase in 
refining costs (excluding crude oil purchase and transport costs), mainly due to higher contract service costs as a result of the 
renegotiation of certain service contracts and inflation adjustments, as well as the increase of crude oil purchases from third parties 
driven by our efforts to maintain our high refinery utilization rates. The price of crude oil purchased from third parties was higher than 
our intersegment price principally due to the generally higher quality of the crude oil purchased, compared to the crude oil basket 
considered in setting our internal transfer price. Additionally, the segment’s operating profit was affected by the implementation in 
November 2007 of a new regime for withholding rates on exports, which significantly decreased our margins on the export sales of 
many hydrocarbon products. Refining cost per barrel, which we calculate as the segment’s cost of sales for the period less crude oil 
purchase costs, divided by the number of barrels produced during the period, was Ps.12.7 in 2008, compared to Ps.10.7 in 2007.  

Refinery output in 2008, including 50% of Refinor’s output (we own 50% of Refinor), reached 328 thousand barrels per day, 

representing a slight 1.8% decrease over the 334 thousand barrels per day processed in 2007.  

Chemicals  
Net sales in 2009 decreased by 22.6% to Ps.3,037 million from Ps.3,923 million in 2008. This decrease was attributable mainly 
to lower sales prices in the domestic market, particularly with respect to methanol and fertilizers, and declines in the average prices of 
exported products (in line with lower international market prices for hydrocarbon products during 2009 compared to 2008) and, to a 
lesser extent, lower exported volumes of methanol.  

Net sales in 2008 increased by 13.5% to Ps.3,923 million from Ps.3,455 million in 2007. The increase in net sales was 
attributable mainly to an increase in the domestic prices of petrochemicals, particularly fertilizers. Export sales decreased in 2008, as 
higher average export prices for petrochemicals, which increased by 12%, were offset by a 23% decrease in exported volumes. 
Additionally, increased export taxes resulting from the application of the new withholding tax regime for exports that came into effect 
in November 2007 resulted in a Ps.270 million increase in export taxes, which are deducted from our gross sales, in 2008 compared to 
2007. Operating income in 2008 increased 135.6% to Ps.1,178 million from Ps.500 million in 2007. The increase in operating income 
was attributable to better margins obtained from our aromatics, as well as to the higher results of Profertil, due mainly to higher 
production of urea and other fertilizers and to the higher prices of such products in the domestic and export markets.  

Liquidity and Capital Resources  

Financial condition  

Total debt outstanding as of December 31, 2009 and 2008 was Ps.6,819 million and Ps.4,479 million, respectively, consisting of 

short-term debt (including the current portion of long-term debt) of Ps.4,679 million and long-term debt of Ps.2,140 million as of 
December 31, 2009, and short-term debt of Ps.3,219 million and long-term debt of Ps.1,260 million as of December 31, 2008. As of 
December 31, 2009 and 2008, a major part of our debt was denominated in U.S. dollars.  

Since September 2001, we have repurchased certain of our publicly-traded bonds in open market transactions on an arms-length 
basis. As of December 31, 2009, we had repurchased approximately U.S.$10 million of our outstanding bonds. We may from time to 
time make additional purchases of, or affect other transactions relating to, our publicly-traded bonds if in our own judgment the 
market conditions are attractive.

Net cash flow provided by operating activities was Ps.9,414 million in 2009, compared to Ps.13,558 million in 2008, a decrease 
of approximately 31%, mainly attributable to lower net proceeds from our receivables with related parties during 2009, as well as a net 
increase in our working capital, resulting from our relatively higher level of receivables and relatively lower level of accounts payable 
in 2009. Net cash flow provided by operating activities was Ps.13,558 million in 2008, compared to Ps.8,756 million in 2007, an 
increase of 55% attributable mainly to net proceeds from our receivables with related parties, improvements in the management of our 
working capital, and higher operating income, excluding amortization of fixed assets, in 2008.  

The principal uses of cash in investing and financing activities in 2009 included Ps.5,636 million in fixed asset acquisitions 
relating mainly to exploration and development activities in our upstream operations, Ps.4,897 million in dividend payments, while net 
proceeds from loans reached Ps.2,016 million. In 2008, the principal uses of cash in investing and financing activities included 
Ps.7,035 million in fixed asset acquisitions relating mainly to our Exploration and Production business unit, and Ps.9,287 million in 
dividend payments (which include dividends declared in respect of 2007 and paid in 2008), while net proceeds from loans reached 
Ps.3,140 million. In 2007, the principal uses of cash in investing and financing activities included Ps.6,163 million in fixed asset 
acquisitions relating mainly to drilling equipment used by our Exploration and Production business unit, Ps.2,360 million in dividend 
payments and Ps.449 million in net repayments of outstanding loans. Our current financing policy is to use cash flows provided by 
operating activities and debt to fund both our investing and operating activities.In response to market financial conditions prevailing in 
Argentina as of the date of this annual report, our financial policy seeks to fund a substantial portion of our short-term debt in local 
currency. Pursuant to this policy, we have several domestic credit lines available from financial institutions. We believe that our level 
of working capital will not affect our business operations, mainly as a result of the expected net cash flow provided by operating 
activities in 2010. However, we are currently making efforts to convert our short-term financial debt into long-term financial debt.  

Repsol YPF and Petersen Energía have agreed in the shareholders’ agreement entered into by them in connection with the 
Petersen Transaction to effect the adoption of a dividend policy under which we would distribute 90% of our net income as dividends, 
starting with our net income for 2007. See “Item 8. Financial Information—Dividend Policy” and “Item 7. Major Shareholders and 
Related Party Transactions—Shareholders’ Agreement.”  

The shareholder’s meeting held on January 8, 2008 approved a notes program for an amount up to U.S.$1 billion. The proceeds 

of any offerings under this program must be used exclusively to invest in fixed assets and working capital in Argentina. On 
September 28, 2009, we issued negotiable obligations under this program in an amount of Ps.205 million, which will accrue interest at 
a variable rate and will mature in March 2011. Additionally, in March 2010 we issued two different series of notes under the same 
notes program: one denominated in Argentine pesos and maturing in September 2011, for a total of Ps.143 million, and a second one, 
denominated in U.S. dollars, for a total of U.S.$70 million, which will mature in March 2013.  

The following table sets forth our commitments for the periods indicated below with regard to the principal amount of our debt, 

as of December 31, 2009, plus accrued but unpaid interest through December 31, 2009:

(1)  These projected amounts include interest due during all the periods presented. Interest on variable rate instruments is calculated 

(2) 

using the rate as of December 31, 2009 for all periods.  
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.  

(3)  Reserves for contingent liabilities under commercial contracts, which amounted to U.S.$605 million as of December 31, 2009, 

(4) 

are not included in the table above since we cannot, based on available evidence, reasonably estimate the settlement dates of 
such contingencies.  
In addition to the contractual obligations detailed in the preceding table, we are also committed to carry out exploration 
activities in certain exploration areas and to make certain investments and expenditures until the expiration of some of our 
concessions. These commitments amounted to approximately U.S.$4.5 billion as of December 31, 2009.  

(5)  The table is presented in U.S.$, which is the company’s functional currency, and not in its reporting currency, as the majority of 

the company’s contractual obligations are originally denominated in U.S.$.  

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

provided” below.  

Covenants in our indebtedness  

Our financial debt generally contains customary covenants for contracts of this nature, including negative pledge, material 

adverse change and cross-default clauses, as well as customary acceleration provisions.  

With respect to a significant portion of our financial debt totaling Ps.6,819 million (U.S.$1,794 million), including accrued 

interest (long- and short-term debt) as of December 31, 2009, we have agreed, among other things and subject to certain exceptions, 
not to establish liens or charges on our assets. In the event of a payment default, the creditors may declare due and immediately 
payable the principal and accrued interest on amounts owed to them. Upon an event of default with respect to other matters, in the 
case of outstanding negotiable obligations amounting to Ps.553 million (U.S.$146 million) (included in the figure above), the trustee 
may declare due and immediately payable the principal and accrued interest on amounts owed if required by holders representing at 
least a percentage that varies between 10 and 25% of the total principal of the outstanding obligations.  

Almost all of our total outstanding financial debt is subject to cross-default provisions. As a result of these cross-default 
provisions, a default on our part or, in certain cases, on the part of any of our consolidated subsidiaries covered by such provisions, 
could result in a substantial portion of our debt being declared in default or accelerated. None of our debt or the debt of our 
consolidated subsidiaries is currently in default.

Credit rating  

As of the date of this annual report, FITCH Ratings (FITCH)’s International Rating for our foreign currency denominated debt 

was BB-, and for our domestic currency denominated debt was BB. FITCH Argentina Calificadora de Riesgo S.A. (FITCH 
Argentina)’s National Rating is AAA for our Negotiable Obligation Programs. FITCH and FITCH Argentina have a stable outlook on 
all of our ratings.  

Moody’s Investors Service’s has rated our domestic currency denominated debt Ba1 and maintains a stable outlook.  

A security rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any 

time by the assigning rating organization.  

We do not have any ratings downgrade triggers that would accelerate the maturity dates of our debt or trigger any other 

contractual obligation on our part. However, a downgrade in our credit rating could have a material adverse effect on the cost of 
renewing existing credit facilities, or obtaining access to new ones in the future. In the past, our main sources of liquidity have been 
our cash flows from operations, bank financings, issuances of debt securities and the proceeds from our divestment plan. Any future 
downgrades will not preclude us from using any of our existing credit lines.  

Guarantees provided  

As of December 31, 2009, we had signed guarantees in relation to the financing activities of Pluspetrol Energy S.A. and Central 

Dock Sud S.A. in amounts of approximately U.S.$10 million (U.S.$6.8 million as of June 24, 2010) and U.S.$17 million (U.S.$14.8 
million as of June 24, 2010), respectively. The corresponding loans mature in 2011 and 2013, respectively.  

Capital investments, expenditures and divestitures  

Capital investements and expenditures  
Capital investments in 2009 totaled approximately Ps.5,832 million. The table below sets forth our capital expenditures and

We have budgeted approximately U.S.$2.1 billion in investments and capital expenditures for 2010, a significant portion of 

which will be dedicated to our exploration and production activities. During the period 2010-2012, we expect to make capital 
expenditures of around U.S.$7.2 billion, principally related to our exploration and production projects, including some to increase 
recovery rates in our fields.  

We intend to finance planned capital expenditures through our internally-generated cash flows and, to the extent necessary, 

borrowings. For a detailed description of our principal current investment projects, see “Item 4. Information on the Company—
Overview.”  

Actual investments and capital expenditures may differ from the above estimates.  

Capital divestitures  
We have not made any significant divestitures in the past three years.  

Off-Balance Sheet Arrangements  

We have entered into certain off-balance sheet arrangements, as described in “—Liquidity and Capital Resources—Guarantees 

provided” and “—Liquidity and Capital Resources—Contractual obligations” above.

ITEM  6. 
Board of Directors  

Directors, Senior Management and Employees  

Our business and affairs are managed by the Board of Directors in accordance with our by-laws and the Argentine Corporations 
Law No. 19,550 (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 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. Since the shareholders’ general 

ordinary meeting held on April 28, 2009, our Board of Directors is composed of 17 directors and 13 alternates.  

In accordance with our by-laws, the Argentine government, sole holder of Class A shares, is entitled to elect one director and 

one alternate. The current director representative of Class A shares was appointed to serve up to a one-year term.  

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.  

The current members of our Board of Directors, the year in which they were appointed and the year their current term expires

None of the members of the Board of Directors owns shares in YPF. Sebastián Eskenazi, Enrique Eskenazi, Matías Eskenazi 
Storey and Ezequiel Eskenazi Storey control Petersen Energía and PEISA (the “Petersen Group”), which own 15.46% of our capital 
stock, and aggregately hold an option to purchase up to an additional 10.0% of our capital stock. See “Item 7. Major Shareholders and 
Related Party Transactions.”  

Pursuant to the shareholders’ agreement between Repsol YPF and Petersen Energía, the composition of our Board of Directors 

shall reflect a proportional representation of Repsol YPF’s and Petersen Energía’s interests in our capital stock. See “Item 7. Major 
Shareholders and Related Party Transactions—Shareholders’ Agreement” for a summary of certain material terms of the shareholders’ 
agreement on the composition of our board of directors and the appointment of directors and officers.

Board practices  

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 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 resolution 
of the shareholders’ meeting. In such cases, a director’s liability will be determined by reference to the performance of such duties as 
long as the director’s appointment and the determination of duties approved by a shareholders’ meeting 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 Argentine Corporations Law require prior approval of the 
Board of Directors or, in the case of an absence of a quorum in a Board of Directors meeting, 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.  

The Audit Committee  

The Transparency Decree (as defined in “Item 9. The Offer and Listing—Argentine Securities Market”) and Resolutions 
No. 400/02 and No. 402/02 of the CNV, require that Argentine public companies 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. A majority of the members of the Audit Committee must be independent directors. See “—
Independence of the Members of our Board of Directors and Audit Committee” below.  

Our Audit Committee was created on May 6, 2004. The members of the Audit Committee currently are: president Mario 
Vázquez, members Mario Blejer, Carlos de la Vega, Federico Mañero and Carlos Bruno, and alternate member Javier Monzón.  

Mario Vázquez was determined by our Board of Directors to be an “Audit Committee Financial Expert” pursuant to the rules 

and regulations of the SEC.  

Executive directors may not sit on the Audit Committee.  

Our Audit Committee, among other things:  
•  

•  

periodically inspects the preparation of our financial and economic information;  
reviews and opines with respect to the Board of Directors’ proposals regarding the designation of the external auditors and 
the renewal, termination and conditions of their appointment;  

90 

 
  
•  

•  

•  

•  

•  

evaluates internal and external audit work, monitors our relationship with the external auditors, and assures their 
independence;  
provides appropriate disclosure regarding operations in which there exists a conflict of interest with members of the 
corporate committees or controlling shareholders;  
opines on the reasonability of the proposals by the Board of Directors for fees and stock option plans of the directors and 
administrators;  
verifies compliance with applicable national or international regulations in 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, which pursuant to its regulations meets as many times as needed and at least once every quarter, held 8 

meetings between February 2009 and March 2010.  

Performing its basic function of supporting the Board of Directors in its oversight duties, the Audit Committee periodically 

reviews economic and financial information relating to us, supervises the internal financial control systems and oversees the 
independence of the external auditors.  

Economic and financial information  

With the help of the Director of Administration and Tax and considering 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.  

In addition, because our shares are traded on the NYSE, pursuant to U.S. law we must include our annual financial information 

in an annual report on Form 20-F, which must be filed with the SEC. The Audit Committee reviews such annual report before it is 
submitted to the SEC.  

Oversight of the internal control system  

To supervise the internal financial control systems and ensure that they are sufficient, appropriate and efficient, the Audit 

Committee oversees the progress of the annual internal audit, which is aimed at identifying our critical risks.  

Throughout each year, the Audit Committee is informed by our internal audit department of the most relevant facts and 

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

We have aligned the internal control system for financial reporting with the requirements established by Section 404 of the 
Sarbanes-Oxley Act, a process supervised by the Audit Committee. These regulations require that, along with the annual audit, a 
report must be presented from our management relating to the design, maintenance and periodic evaluation of the internal control 
system for financial reporting, accompanied by a report from our external auditor. Several of our departments are involved in this 
activity, including the internal audit department. Our external auditor reported on our internal control system for financial reporting as 
of December 31, 2009.  

Relations with the external auditors  

The Audit Committee maintains a close relationship with the external auditors, allowing it to make a detailed analysis of the 

relevant aspects of the audit of financial statements and to obtain detailed information on the planning and progress of the work.  

The Audit Committee also evaluates the services provided by our external auditors, determines whether the condition of 

independence of the external auditors, as required by applicable law, is met and monitors the performance of external auditors to 
ensure that it is satisfactory.  

As of December 31, 2009, and as a consequence of the evaluation process described in the paragraph above, the Audit 
Committee had no objections to the designation of Deloitte & Co. S.R.L. as our external auditors of the financial statements for the 
year ending December 31, 2010. The shareholders at a meeting held on April 14, 2010 approved the designation of Deloitte & Co. 
S.R.L. as external auditors of the financial statements for the year ended December 31, 2010.  

91 

 
  
Independence of the Members of our Board of Directors and Audit Committee  

Pursuant to CNV regulations, a director is not considered independent when such director (i) owns at least a 35% equity interest 

in a company, or a lesser interest if the director has the right to appoint one or more directors of the company, which we refer to as a 
“Significant Participation,” or has a Significant Participation in another company that in turn has a Significant Participation in the 
company or a significant influence on the company (“significant influence” is defined by Argentine GAAP); (ii) is a member of the 
Board of Directors of, or depends on, shareholders, or is otherwise related to shareholders, who have a Significant Participation in the 
company or another company in which these shareholders have a direct or indirect Significant Participation or significant influence; 
(iii) is or has been in the previous three years an employee of the company; (iv) has a professional relationship with, or is a member of 
a company that maintains professional relationships with, or receives remuneration (other than that received in consideration of his 
performance as a director) from the company or any of its shareholders who has a direct or indirect Significant Participation in or 
significant influence on the company, or with a third-party company that has a direct or indirect Significant Participation or a 
significant influence; (v) directly or indirectly sells or provides goods or services to the company or to any of its shareholders who has 
a direct or indirect Significant Participation in or significant influence on the company for an amount exceeding his remuneration as a 
member of the Board of Directors or audit committee; or (vi) is the spouse or parent (up to second grade of affinity or up to fourth 
grade of consanguinity) of persons who, if they were members of the Board of Directors or Audit Committee, would not be 
independent, according to the above-listed rules.  

As of the date of this annual report, Messrs. Santiago Carnero, Carlos Bruno, Carlos de la Vega, Federico Mañero, Mario 

Vázquez and Mario Blejer qualified as independent members of our Board of Directors under the above-described criteria.  

Disclosure Committee  

In February 2003, we created a Disclosure Committee to:  
•  

monitor the overall compliance with regulations and principles of conduct of voluntary application, especially in relation 
to listed companies and their corporate governance;  
direct, establish and maintain procedures for the preparation of accounting and financial information to be approved and 
filed by us or which is generally released to the markets;

statements included in annual and quarterly reports, as well as any accounting and financial information to be approved 
and filed by us, are accurate, reliable and clear;

approved and filed;  
assume the activities that, according to U.S. laws and SEC regulations, are applicable to us and may be assumed by 
disclosure committees or other internal committees of a similar nature, especially those activities relating to the SEC 
regulations dated August 29, 2002 (“Certification of Disclosure in Companies’ Quarterly and Prospectus” —SEC Release 
number 33-8124), in relation to the support for the certifications by our Chief Executive Officer and Chief Financial 
Officer as to the existence and maintenance by us of adequate procedures and controls for the generation of the 
information to be included in its annual reports on Form 20-F, and other information of a financial nature;  
take on activities similar to those stipulated in SEC regulations for a disclosure committee with respect to the existence 
and maintenance by us of adequate procedures and controls for the preparation and content of the information to be 
included in the annual financial statements, and any accounting or financial information to be filed with the CNV and 
other regulators of the stock markets on which our stock is traded; and  
formulate proposals for an internal code of conduct on the stock markets that follow applicable rules and regulations or 
any other standards deemed appropriate.

Directors and may be terminated at any time without notice.  

Share Ownership of Executive Officers  

None of our executive officers owned any of our shares or held vested options to purchase YPF stock as of May 4, 2010.  

Compliance with NYSE Listing Standards on Corporate Governance  

On November 4, 2003, the SEC approved rules proposed by the NYSE intended to strengthen corporate governance standards 

for listed companies.  

In accordance with the NYSE corporate governance rules, as of July 31, 2005, all members of the Audit Committee were 
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 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. Because more than 50% of our voting stock is held by another company, Repsol 
YPF, we would not be required to comply with the following NYSE corporate governance requirements even if we were a U.S. 
company: (i) having a majority of independent directors, (ii) corporate governance committee requirements, and (iii) compensation 
committee requirements.  

93 

 
  
 
 
  
  
  
  
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 nominations 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 required.  

Separate meetings for non-management directors  
In accordance with NYSE corporate governance rules, independent directors must meet periodically outside of the presence of 

the 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, the members of 
which are independent directors.  

Code of Ethics  

We have adopted a code of ethics applicable to the Board of Directors and all employees. Since its effective date on August 15, 

2003, we have not waived compliance with or amended the code of ethics.  

Compensation of Directors and Officers  

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) 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 income based on the amount of 
dividends, if any, are paid. The compensation of the president and other directors acting in an executive capacity, together with the 
compensation of all other directors, requires the ratification of an ordinary general shareholders’ meeting as provided by Argentine 
law. The compensation of the members of the Supervisory Committee is determined by the shareholders at the ordinary shareholders’ 
meeting.  

For the period ended December 31, 2009 the aggregate compensation accrued or paid to the members of the Board of Directors 

and YPF’s executive officers for services in all capacities was Ps.59.7 million.  

During 2009, YPF’s performance-based compensation programs included a bonus plan for approximately 5,000 employees. 

This bonus plan provides for cash to be paid to its participants based on a measurable and specific set of objectives under Repsol 
YPF’s Management by Objectives program and the results of the review of individual performance. All of the participants are non-
unionized YPF employees. The participation of each eligible employee in the bonus plan ranges from 15% to 55% of such employee’s 
annual base salary. Bonus percentages are fixed by the president of Repsol YPF with the approval of Repsol YPF’s Compensation 
Committee at the beginning of each calendar year. The total amount of bonuses awarded under the bonus plan cannot exceed 90% of 
the individual maximum participation and will be linked to Repsol YPF’s net cash flow.  

The amount set aside or accrued by YPF to provide pension, retirement or similar benefits to members of its Board of Directors 

or officers with executive responsibilities amounted to a total of Ps.5.6 million in 2009.  

YPF’s directors do not have any service contracts with YPF.  

Supervisory Committee  

The Supervisory Committee is responsible for overseeing compliance by the management and the Board of Directors with the 

Argentine 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 consisting of three to five members and three to five alternate members, 
elected to one-year terms. The Class A shares are entitled to elect one member and one alternate member of the Committee so long as 
one share of such class remains outstanding. The holders of Class D shares 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 meeting requires the presence of all 

94 

 
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.” For the year 2009, the aggregate compensation paid to the members of the Supervisory 
Committee was Ps.1.58 million.  

The current members of the Supervisory Committee, the year in which they were appointed and the year their current term 

expires are as follows:

Employee Matters  

As of December 31, 2009, we had 12,140 employees, including 6,158 employees of the Refining and Marketing business 
segment, 2,277 employees of the Exploration and Production business segment, and 564 employees of the Chemicals business 
segment.  

Approximately 42% of our employees are represented by the labor union “Federación Sindicatos Unidos Petroleros e 
Hidrocarburíferos” (SUPeH) that negotiates with us labor agreements and salaries which apply to YPF and OPESSA unionized 
employees. The SUPeH is permanently negotiating with us, and we maintain a good level of communication. In general, labor unions 
related to the petrochemical industry aligned with general wage increases given by the General Unions Confederation (Confederación 
General del Trabajo or “CGT”).  

At the end of 2006, we began new negotiations with the SUPeH, that resulted in our extending our agreements with such unions 
until the end of 2010. The negotiations involved the economic and social conditions for employees of ours and of third parties that are 
addressed in the labor agreement. We consider our current relations with our workforce to be generally good.  

In addition, labor conditions and salaries of third-party employees working with YPF and OPESSA in refineries, oil fields and 

gas stations, are negotiated with sixteen other unions.  

96 

 
  
  
As part of its privatization, YPF restructured its internal organization and significantly reduced the number of its employees. 

YPF reduced its work force from over 51,000 employees (including approximately 15,000 personnel under contract) at December 31, 
1990 to approximately 7,500 at December 31, 1993. YPF paid to the employees affected by these reductions the termination payments 
required under Argentine labor laws which amounted to Ps.686 million. A substantial majority of lawsuits which were originated as a 
consequence of said restructuring process have been brought by former employees who allege that they received insufficient 
severance payments in connection with their dismissal and various job-related illnesses, injuries, typically seeking unspecified relief.  

As of December 31, 2009, YPF was a party in approximately 1,681 labor lawsuits which relate to events or acts that took place 

after December 31, 1990. The outcome of said lawsuits depends 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 character 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.  

Maxus (a YPF subsidiary) has a number of trustee noncontributory pension plans covering substantially all its full-time 

employees. The benefits provided by these plans are based on the number of years of employment and the compensation earned 
during those years. This company has other noncontributory pension plans for executive officers, selected key employees and former 
employees of the Maxus group. The Maxus Energy Corporation career average pension plan was frozen effective March 1, 2007. The 
Maxus Energy Corporation savings plan was amended effective March 1, 2007 to include a non-elective component, through which 
the plan’s sponsor contributes 7.5% of the employees’ annual base salary. Maxus also grants benefits for health care, life insurance 
and other social benefits to some of its employees who retire early. The amounts payable accrue over the employees’ years of service. 
During March 2008, YPF Holdings purchased a group annuity contract from an insurance company to settle the liability associated 
with the benefits under certain of Maxus’ defined benefits plans, with a one-time premium payment of U.S.$115 million. The 
assumption by the insurance company of liability under the plans was effective on March 20, 2008, the date the premium was paid by 
YPF Holdings.  

As of December 31, 2009 there were also approximately 30,415 third-party employees under contract, mostly with large 

international service providers. Although we have policies regarding compliance with labor and social security obligations by its 
contractors, we are not in a position to ensure that contractors’ employees will not initiate legal actions to seek indemnification from 
us based upon a number of Argentine judicial labor court precedents recognizing joint and several liability between the contractor and 
the entity to which it is supplying services under certain circumstances.

The following are summaries of certain material terms of the agreements entered into by Repsol YPF, Petersen Energía and 

certain of their respective affiliates in connection with the Petersen Transaction and the Petersen Options (as defined below), as 
described in Repsol YPF’s public filings.  

Share Purchase Agreement and Related Financing Agreements  

Pursuant to the share purchase agreement entered into by Petersen Energía and Repsol YPF in 2008, Petersen Energía purchased 

58,603,606 ADSs, representing 14.9% of our outstanding capital stock, from Repsol YPF for a total purchase price of U.S.$2,235 
million, or U.S.$38.13758 per ADS (the “Petersen Transaction”). Petersen Energía’s purchase of our securities was financed by the 
drawdown of U.S.$1,026 million under a senior secured term loan facility provided by certain financial institutions, borrowing of 
U.S.$1,015 million under a seller credit agreement entered into with Repsol YPF and equity provided by Petersen Energía’s 
shareholders. The seller credit agreement matures on February 21, 2018. Principal payments are required to be made at certain 
periodic intervals commencing in 2013 until the maturity date. The loan under the seller credit agreement bears interest at 8.12% per 
year until May 15, 2013, and thereafter at 7.0% per year, and contains other customary terms and provisions.  

Securities purchased by Petersen Energía are pledged as collateral under the senior secured term loan facility and the seller 

credit agreement. The seller credit agreement is subordinated to the senior secured term loan facility.  

Option Agreements  

Repsol YPF granted certain affiliates of Petersen Energía, an option to purchase the number of Class D shares or ADSs 

amounting to 0.1% of our capital stock, pursuant to the first option agreement (which was exercised in May 2008) (the “First Petersen 
Option”), and an option to purchase an additional number of Class D shares or ADSs amounting to 10.0% of our capital stock 
(collectively, the “Option Shares”), pursuant to the second option agreement, subject to certain terms and conditions (the “Second 
Petersen Option” and, together with the First Petersen Option, the “Petersen Options”). The Second Petersen Option expires on 
February 21, 2012. The exercise price per Option Share shall be determined in accordance with the following formula: (i) U.S.$15 
billion multiplied by the consumer price index published monthly by the United States Bureau of Labor Statistics for the period from 
the date of the option agreements through the exercise date, (ii) plus or minus our accumulated results from the date of the option 
agreements through the exercise date (with certain adjustments for taxes paid), determined based on our financial statements for the 
fiscal years ending after the date of the option agreements, (iii) minus dividends paid from the date of the option agreements through 
the exercise date, (iv) plus or minus any changes in our share capital, (v) divided by the number of shares outstanding on the exercise 
date.  

The beneficiaries of the Second Petersen Option may exercise their purchase rights on one or more occasions during the 

exercise period of such second option agreement.  

98 

 
  
 
 
 
  
  
  
 
 
 
 
 
 
 
  
Subject to certain terms and conditions contained in the Petersen Options, Repsol YPF has agreed to provide financing of up to 
48% of the exercise price required to be paid for the Option Shares purchased by certain members of the Eskenazi family pursuant to 
the Petersen Options. Repsol YPF had also agreed to finance or guarantee the financing of up to 100% of the price that the members 
of the Eskenazi family would be required to pay to purchase shares from other shareholders through a mandatory tender offer as a 
result of Petersen Energía and its affiliates, including certain members of the Eskenazi family, acquiring an interest in our capital stock 
of more than 15%. This commitment is limited to a maximum amount equivalent to the price necessary to purchase Class D shares or 
ADSs equal to 0.9% of our capital stock, which corresponds to the percentage of shares that were not owned by Repsol YPF prior to 
the Petersen Transaction.  

The beneficiaries of the Petersen Options agreed that, if they exercise the Second Peterson Option, they will not transfer for a 

period of five years the 10% of our outstanding capital stock that is subject to the second option agreement, but have not made such an 
agreement as to the 0.1% of our capital stock that was acquired pursuant to the First Peterson Option.  

Shareholders’ Agreement  

Petersen Energía, Repsol YPF and certain affiliates of Repsol YPF entered into a shareholders’ agreement on February 21, 2008 

in connection with the Petersen Transaction establishing certain rights and obligations in connection with our governance and certain 
procedures for and limitations on transfers of our shares, among other matters. The following is a summary of certain material terms 
of the shareholders’ agreement based on Repsol YPF’s public filings.  

Voting at Shareholders’ Meetings  
Repsol YPF and Petersen Energía have agreed to discuss and reach agreement on their voting with respect to proposals 
presented at shareholders’ meetings involving certain matters, including certain increases or any reductions in our capital (except 
reductions that are legally required), the merger, divestiture or dissolution of our company or certain of our subsidiaries, the divestiture 
of material assets of our company or certain of our subsidiaries, the modification of our by-laws, and the designation or removal of our 
external auditors, among other matters. In the event that Repsol YPF and Petersen Energía cannot reach an agreement on any of these 
matters, they have agreed to vote against such matters.  

Composition of our Board of Directors  
Repsol YPF and Petersen Energía have agreed that the composition of our Board of Directors shall reflect a proportional 
representation of Repsol YPF’s and Petersen Energía’s interests in our capital stock, with (i) Repsol YPF retaining the right to appoint 
the majority of the members of our Board of Directors for so long as it holds the majority of our capital stock, and (ii) Petersen 
Energía having the right to appoint at least five members to our Board (or three members in the case that its interest in our outstanding 
capital stock falls below 10%).  

Appointment of Directors and Officers and Certain Board Decisions  
Repsol YPF and Petersen Energía have agreed that the Chairman of our Board of Directors and our Chief Operating Officer 

shall be designated by Repsol YPF while our Chief Executive Officer will be designated by Petersen Energía.  

Certain decisions of our Board of Directors shall require the affirmative vote of the directors representing Repsol YPF and 

Petersen Energía, including any action that results in any of the specific matters discussed under “—Voting at Shareholders’ 
Meetings” above, the reduction of our direct or indirect interest in certain of our subsidiaries, the contracting of debts, guarantees or 
investments that contractually limit the payment of dividends or cause our consolidated debt to EBITDA ratio to reach or exceed 3:1, 
undertake non-budgeted investments or acquisitions that individually exceed U.S.$250 million, and the requesting of the declaration 
of insolvency or bankruptcy, among other matters. In the event that Repsol YPF and Petersen Energía cannot reach an agreement on 
any of these specific matters, they have agreed to instruct their directors to vote against such matters.  

Lock-Ups and Transfer Restrictions  
Petersen Energía has agreed not to sell any shares of our capital stock for a period of five years, subject to certain exceptions, 
including the condition that Repsol YPF continues to hold at least 35% of our outstanding capital stock. In addition, if our dividend 
payments are insufficient for Petersen Energía to meet its obligations under the senior secured term loan facility, or if Petersen Energía 
repays the senior secured term loan facility in full, Petersen Energía may sell shares of our capital stock, so long as Petersen Energía 
maintains a minimum interest in our capital stock of between 10% and 15% (depending on whether the beneficiaries of the Petersen 
Options have fully exercised the Petersen Options and excluding certain dilution events in respect of capital increases).  

99 

 
Repsol YPF has agreed to hold at least 50.01% of our capital stock for a period of at least five years, unless Petersen Energía 

repays the senior secured term loan facility in full. Once the senior secured term loan facility has been repaid in full, Repsol YPF has 
agreed to hold at least 35% of our capital stock, so long as Petersen Energía maintains a minimum interest in our capital stock of 
between 10% and 15% (depending on whether its affiliates that are beneficiaries of the Petersen Options have fully exercised the 
Petersen Options and excluding certain dilution events in respect of capital increases), provided that Repsol YPF may sell shares to a 
purchaser that is a “first-tier” company in the oil and gas industry and agrees to be bound by the terms of the shareholders’ agreement.  

After five years: (i) Petersen Energía may transfer its shares without limitation; and (ii) so long as Petersen Energía maintains a 

minimum interest in our capital stock of between 10% and 15% (depending on whether its affiliates that are beneficiaries of the 
Petersen Options have fully exercised the Petersen Options and excluding certain dilution events in respect of capital increases), 
Repsol YPF must maintain an interest that, combined with Petersen Energía’s holdings, amounts to 40% of our outstanding capital 
stock, subject to certain conditions, provided that Repsol YPF may sell shares to a purchaser that is a “first-tier” company in the oil 
and gas industry and agrees to be bound by the terms of the shareholders’ agreement.  

Tag-Along Rights, Right to Participate in Public Offering and Right of First Refusal  
If Petersen Energía has repaid the senior secured term loan facility in full, when Repsol YPF sells more than 5% of our 
outstanding capital stock, Petersen Energía shall have a pro rata tag-along right with respect to such sale by Repsol YPF. Petersen 
Energía also has a right to participate, on a pro rata basis, in any public offering of our outstanding capital stock conducted by Repsol 
YPF.  

Additionally, when Repsol YPF or Petersen Energía sells a block of our shares representing greater than 10% of our capital 

stock, the other party shall have a right of first refusal to purchase such shares, subject to certain terms and conditions.  

Acquisition of Certain of Repsol YPF’s Latin American Assets  
Repsol YPF and Petersen Energía have agreed to allow us to evaluate the possible acquisition, at market price, of certain 

specified Latin American assets of Repsol YPF in order to expand and diversify our business.  

Dividends  
Repsol YPF and Petersen Energía have agreed to effect the adoption of a dividend policy under which we would distribute 90% 

of our net income as dividends, starting with our net income for 2007. They have also agreed to vote in favor of requiring us to 
distribute an additional dividend of U.S.$850 million, which was paid jointly with the ordinary dividends in 2008 and 2009.  

Tender Offer by Petersen Energía  
Repsol YPF agreed not to participate in the tender offer for our shares that Petersen Energía or its affiliates were required to 

make when they acquired 15% or more of our outstanding capital stock (as a result of its exercise of one of the Petersen Options, or 
otherwise).  

Duration and Termination  
The shareholders’ agreement shall remain in effect during our existence, but is subject to immediate termination if Repsol 

YPF’s holdings of our capital stock fall below 12.5% or Petersen Energía’s holdings of our capital stock fall below 10%. The 
shareholders’ agreement is also subject to termination if there are certain defaults under the shareholders’ agreement, or if, within 
thirty days of the bankruptcy of either party, the bankrupt party cannot provide a sufficient guaranty to the other party.  

Registration Rights and Related Agreements  

Under the terms of the registration rights agreement between us, Repsol YPF and the financial institutions providing the senior 

secured term loan facility, we have agreed to file a resale shelf registration statement under the Securities Act with respect to the 
ADSs sold in the Petersen Transaction, have it declared effective by the SEC, and keep it continuously effective until certain specified 
conditions have been met. On February 20, 2008, we filed such shelf registration statement on Form F-3 with the SEC. Upon any 
acceleration of the senior secured term loan facility following the occurrence and continuation of an event of default under such 
facility, Credit Suisse, London Branch, the administrative agent acting on behalf of the lenders under the senior secured term loan 
facility as holders of such pledged securities, may sell such securities under the shelf registration statement after giving us notice, 
provided that we may suspend the use of the registration statement upon the occurrence of certain specified events. Such securities and 
the associated registration rights may be transferred by any holder.  

100 

 
  
In the event that we fail to keep a continuously effective resale shelf registration statement and an acceleration of the senior 

secured term loan facility following an occurrence and continuation of an event of default under such facility occurs, we are required 
to pay certain specified damages to the holders of the securities required to be registered. The registration rights agreement provides 
that the selling shareholders and us will indemnify each other and their and our respective directors, officers, agents, employees and 
controlling persons against specific liabilities in connection with the offer and sale of the ADSs, including liabilities under the 
Securities Act, or will be entitled to contribution in connection with those liabilities. In addition, Repsol YPF and Petersen Energía 
PTY Ltd., the parent holding company of Petersen Energía, S.A., have agreed in a separate agreement to indemnify us against certain 
specific losses resulting from our agreement to indemnify the selling shareholders and their directors, officers and controlling persons 
pursuant to the registration rights agreement (excluding losses resulting from a final judgment determining the existence of a material 
misstatement or omission of fact contained in our resale shelf registration statement or a prospectus included therein, or a settlement 
based on such claims). Repsol YPF or Petersen Energía S.A. will pay all of our expenses incidental to the registration, offering and 
sale of the ADSs to the public (subject to the caps and limitations set forth in the registration rights agreement), and each selling 
shareholder will be responsible for payment of commissions, concessions, fees and discounts of underwriters, broker-dealers and 
agents.  

We have also entered into a separate registration rights agreement with respect to the Option Shares, with terms and conditions 
that are substantially similar to those contained in the registration rights agreement entered into with respect to the ADSs sold in the 
Petersen Transaction.  

Related Party Transactions  

All material transactions and balances with related parties are set forth in Note 7 to the Audited Consolidated Financial 

Statements. The principal such transactions were our sales of refined and other products to certain affiliates (which amounted to 
Ps.1,378 million in 2009), and our purchase of petroleum and other products that we do not produce ourselves from certain affiliates 
(which amounted to Ps.446 million in 2009). The prices of the transactions with related parties approximate the amounts charged by 
and/or to us by unrelated third parties.  

In addition, Repsol YPF and Petersen Energía PTY Ltd., the parent holding company of Petersen Energía, have agreed to 

indemnify us against certain specific losses resulting from our agreement to indemnify the selling shareholders and their directors, 
officers and controlling persons pursuant to the registration rights agreements we have entered into in connection with the Petersen 
Transaction (excluding losses resulting from a final judgment determining the existence of a material misstatement or omission of fact 
contained in our resale shelf registration statement or a prospectus included therein, or a settlement based on such claims). Repsol YPF 
or Petersen Energía will pay all of our expenses incidental to the registration, offering and sale of the securities registered hereby to 
the public. See “—Registration Rights and Related Agreements.”

Information on the Company—Overview.”  

Argentine Law Concerning Related Party Transactions  

Section 73 of the Transparency Decree 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 73 of the Transparency Decree, as amended by Decree No. 1020/03, “significant amount” means an 

amount that exceeds 1% of the issuer’s net worth as reflected in the latest approved financial statements, provided this amount exceeds 
Ps.300,000. For purposes of the Transparency Decree, “related party” means (i) directors, members of the supervisory committee, 
managers; (ii) the persons or entities that control or hold a significant participation in the company or in its controlling shareholder (at 
least 35% of its capital stock, or a lesser amount when they have the right to appoint one or more directors, or have other shareholder 
agreements related to the management of the company or its controlling shareholder); (iii) any other company under common control; 
(iv) direct relatives of the persons mentioned in (i) and (ii); or (v) companies in which the persons referred to in (i) to (iv) hold directly 
or indirectly significant participations.  

The acts or contracts referred to above, immediately after being approved by the board of directors, shall be disclosed to the 

CNV, making express indication of the audit committee’s or independent valuation firm’s opinion, as the case may be. Also, 
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.

Legal Proceedings  
Argentina  

The Privatization Law provides that the Argentine State shall be responsible, and shall hold us harmless, for any liabilities, 
obligations or other commitments existing as of December 31, 1990 that were not acknowledged as such in the financial statements of 
Yacimientos Petrolíferos Fiscales Sociedad del Estado as of that date arising out of any transactions or events that had occurred as of 
that date, provided that any such liability, obligation or other commitment is established or verified by a final decision of a competent 
judicial authority. In certain lawsuits related to events or acts that took place before December 31, 1990, we have been required to 
advance the payment of amounts established in certain judicial decisions, and have subsequently been reimbursed or are currently in 
the process of requesting reimbursement from the Argentine government of all material amounts in such cases. We are required to 
keep the Argentine government apprised of any claim against us arising from the obligations assumed by the Argentine government. 
We believe we have the right to be reimbursed for all such payments by the Argentine government pursuant to the above-mentioned 
indemnity, which payments in any event have to date not been material. This indemnity also covers fees and expenses of lawyers and 
technical consultants subject, in the case of our lawyers and consultants, to the requirement that such fees and expenses not be 
contingent upon the amounts in dispute.  

Reserved, probable contingencies  
Reserves totaling Ps.1,769 million, Ps.1,821 million, and Ps.1,898 million as of December 31, 2009, 2008 and 2007, 

respectively, have been established to provide for contingencies which are probable and can be reasonably estimated. In the opinion of 
our management, in consultation with our external counsel, the amount reserved reflects the best estimation, based on the information 
available as of the date of this annual report, of the probable outcome of the mentioned contingencies. The most significant legal 
proceedings and claims reserved are described in the following paragraphs.  

CNDC anti-competitive activity disputes. On March 22, 1999, we were notified of Resolution No. 189/99 from the former 
Secretariat of Industry, Commerce and Mining of Argentina, which imposed a fine on us of Ps.109 million, stated Argentine pesos as 
of that date, based on the interpretation that we had purportedly abused our dominant position in the bulk LPG market due to the 
existence of different prices between the exports of LPG and the sales to the domestic market from 1993 through 1997. In July 2002, 
the Argentine Supreme Court confirmed the fine, and we made the claimed payment. Additionally, Resolution No. 189/99 provided 
for the commencement of an investigation in order to prove whether the penalized behavior continued from October 1997 to March 
1999. On December 19, 2003, the CNDC completed its investigation and charged us with abuse of dominant market position during 
this period. On January 20, 2004, we answered the notification by (i) claiming the application of the statutes of limitations and 
alleging the existence of defects in the imputation procedure (absence of majority in the resolution that decided the imputation and 
prejudgment by its signers); (ii) arguing the absence of abuse of dominant position; and (iii) offering the corresponding evidence.  

Given that the Argentine Supreme Court has previously established under Law No. 22,262 that the statute of limitations for 

administrative infractions is two years, we believe that our defense based on the statute of limitations is solid. Since the imputed 
conduct occurred before September 29, 1999, which is the effective date of the new law, we believe that the law applicable to the 
proceeding is Law No. 22,262 instead of the new Antitrust Protection Law (No. 25,156). We filed appeals with the National Economic 
Criminal Court: (i) on July 29, 2003, in view of the rejection by the CNDC of the motion to overturn the resolution that ordered the 
opening of the preliminary investigations without deciding in advance on the statute of limitations defense claimed by us; and (ii) on 
February 4, 2004, in view of the rejection by the CNDC of the motion to overturn the resolution that ordered the charge because of a 
lack of majority and prejudgment. On April 13, 2004, the National Court of Appeals in Criminal Economic Matters sustained the 
appeal filed by us on the grounds of lack of majority of the CNDC in passing the objected resolution. On August 31, 2004, we 
appealed the resolution passed by the CNDC that rejected our statute of limitations defense. The CNDC accepted the appeal and 
referred the proceedings to Chamber II of the National Court of Appeals in Federal Civil and Commercial Matters, which 
subsequently referred the proceeding to Chamber B of the National Court of Appeals in Criminal Economic Matters. On March 3, 
2006, the CNDC decided on the evidence that we shall produce during this proceeding. During August and September 2007, hearings 
involving the testimony of witnesses proposed by us took place. On August 12, 2008, Chamber B of the National Court of Appeals in 
Criminal Economic Matters rejected our statute of limitations argument. We have appealed this decision. Upon Chamber B’s 
confirmation of the CNDC’s resolution, YPF filed a cassation and an extraordinary appeal on the basis that the CNDC bases its 
arguments on Law No. 22,262, while Chamber B relies on the application of Law No. 25,156. Chamber B of the National Court of 
Appeals in Criminal Economic Matters rejected both appeals. YPF has consequently presented two complaint appeals: one against the 
rejection of the cassation appeal (rejected on December 18, 2008) and another against the rejection of the extraordinary appeal 
(rejected on February 17, 2009). Both appeals are under evaluation. Regarding the administrative proceedings before the CNDC, the 
evidence production period has ended. Additionally, on November 25, 2009, we presented our closing statement. On December 22, 

102 

 
2009, Chamber IV of the Court of Cassation rejected our cassation appeal against Chamber B of the National Court of Appeals in 
Criminal Economic Matters’ decision. The extraordinary appeal is still pending before the Supreme Court. Furthermore, on 
December 21, 2009, YPF filed another claim concerning the statute of limitations before the CNDC. On April 19, 2010 the CNDC 
rejected this claim and YPF appealed such decision.  

Despite our arguments, the mentioned circumstances make evident that, preliminarily, the CNDC denies the defenses filed by us 

and that it is reluctant to modify the doctrine provided by the Resolution No. 189/1999.  

Alleged defaults under natural gas supply contracts. Since 2004, the Argentine Secretariat of Energy and the Undersecretariat of 
Fuels, through Rule No. 27/04, Resolutions No. 265/04, 659/04, 752/05, 1329/06 and 599/07, have on various occasions instructed us 
to supply certain quantities of natural gas to the Argentine domestic market, in each case notwithstanding the lack of a contractual 
commitment on our part to do so. In addition, the Argentine government has, at various times since 2004, imposed direct volume 
limitations on natural gas exports in different ways. As a result of these measures, from 2004 to the present, 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.  

We appealed these measures, but, pending favorable final resolution of such appeals, we have been obliged to comply in order 

to avoid greater losses to us and our export customers that could be occasioned by the revocation of our export permits or other 
penalties. We informed our natural gas export customers of our position that these governmental measures constitute an event of force 
majeure that releases us from any contractual or extra-contractual liability deriving from the failure to deliver the agreed upon 
volumes of gas. Some of our customers have rejected our position and have sought damages and/or penalties for breach of supply 
commitments under a contractual “deliver or pay” clause, which claims have been rejected by us.  

We have been in pre-arbitral settlement discussions with Electroandina S.A. and Empresa Eléctrica del Norte Grande S.A., 

which have sought damages from us under the “deliver-or-pay” clause. These companies have claimed damages through November 
2006 in a total amount of approximately U.S.$41 million and, from December 2006 through September 2007, for an additional total 
amount of U.S.$52 million. We have opposed such claims. Furthermore, the above-mentioned companies have notified the formal 
start-up period of negotiations previous to any arbitration proceedings. Although such period is overdue, YPF has not been notified of 
the initiation of the arbitration proceedings.  

Additionally, on June 25, 2008, AES Uruguaiana Emprendimientos S.A. (AESU) claimed damages in a total amount of 

U.S.$28.1 million for missed deliveries of natural gas volumes during the period September 16, 2007 through June 25, 2008. On 
July 16, 2008, AESU also claimed damages in a total amount of U.S.$2.7 million for missed deliveries of natural gas volumes during 
the period January 18, 2006 through December 1, 2006. We have contested both of these claims. Both parties have suspended the 
fulfillment of their obligations under the contract. On September 15, 2008, AESU notified YPF the interruption of the fulfillment of its 
commitments alleging delay and breach of YPF’s obligations. YPF has rejected this notification. On December 4, 2008, YPF notified 
that having ceased the force majeure conditions, pursuant to the contract in force, it would suspend its delivery commitments, due to 
the repeated breaches of AESU’s obligations. This notification was also rejected. On December 30, 2008, AESU rejected YPF’s right 
to suspend its natural gas deliveries and on March 20, 2009, AESU notified YPF that it was terminating the contract. See “—
Arbitration with AES Uruguaiana Emprendimentos S.A. (AESU), Companhia de Gás do Estado do Río Grande do Sul (Sulgás) and 
Transportadora de Gas del Mercosur S.A. (TGM).”  

In addition, YPF is subject to certain claims related to transportation fees and charges associated with transportation services 
under contracts associated with natural gas exports. One of the parties to these contracts initiated mediation proceedings with us in 
order to determine the merits of its claim. The mediation proceedings, did not result in an agreement and, on March 12, 2010, YPF 
was notified of the lawsuit filed by such company claiming the fulfillment of contractual obligations and the payment of unpaid 
invoices while reserving the right to claim for damages. YPF has answered the mentioned lawsuit. In the opinion of our management, 
this matter will not have a material adverse effect on our results of operations.  

La Plata refinery environmental disputes. On June 29, 1999, a group of three neighbors of the La Plata refinery filed claims for 

the remediation of alleged environmental damages in the peripheral water channels of the refinery, investments related to 
contamination and compensation for alleged health and property damages as a consequence of environmental pollution caused by YPF 
prior to and after privatization. We notified the executive branch of the Argentine government that there is a chance that the tribunal 
may find us responsible for the damages. In such event, due to the indemnity provided by Law No. 24,145 and in accordance with that 
law, we shall be allowed to request reimbursement of the expenses for liabilities existing on or prior to January 1, 1991 (before 
privatization) from the Argentine government.  

On December 27, 2002, a group of 264 claimants who resided near the La Plata refinery requested compensation for alleged 
quality of life deterioration and environmental damages purportedly caused by the operation of the La Plata refinery. The amount 
claimed is approximately Ps.72 million. We filed a writ answering the complaint. There are three similar additional claims raised by 
three groups of 120, 343, and 126 neighbors, respectively. The first group has made a claim for compensation of approximately Ps.22 
million, the second group has made a claim for compensation of approximately Ps.60 million and the third one has made a claim of 
approximately Ps.21.5 million, in addition to a request for environmental cleanup.  

103 

 
On December 17, 1999, a group of 37 claimants who resided near La Plata refinery, demanded the specific performance by us of 

different works, installation of equipment, technology and execution of work necessary to stop any environmental damage, as well as 
compensation for health damages alleged to be the consequence of gaseous emissions produced by the refinery, currently under 
monitoring.  

Quilmes claims. We have been notified of 34 judicial claims filed by neighbors living near the riverside in Quilmes, in the 

province of Buenos Aires, as a consequence of a leak related to the La Plata – Dock Sud pipeline, which occurred in 1988 as third 
parties damaged and stole fuel from the pipeline, which was then repaired by Yacimientos Petrolíferos Fiscales. One of the claims has 
been filed by a group of people that allegedly live in this area and have requested the remediation of environmental damages and the 
payment of approximately Ps.47 million plus interest as compensation for alleged personal damages for hydrocarbons exposure. We 
have answered the complaint requesting its rejection and impleading the Argentine government. We have also notified the Argentine 
government of the existence of this claim and that we plan to request that it hold us harmless and indemnify us against any liability 
derived from this lawsuit, as provided by Law No. 24,145. The Argentine government, through an administrative decision, has denied 
any responsibility to indemnify us for this matter, and we have sued the Argentine government to obtain a declaratory judgment 
declaring this administrative decision null and void. Such declaratory judgment is still pending. There are 33 other judicial claims that 
have been brought against us based on similar allegations, amounting to approximately Ps.16.7 million. Additionally, we are aware of 
the existence of other actions brought against us that have not yet been served and which are based on similar allegations. As of the 
date of this annual report, a remediation plan is being performed in the affected area, under the supervision of the environmental 
authority of the province of Buenos Aires.  

Tax claims. We have received several claims from the Federal Administration of Public Revenue (Administración Federal de 

Ingresos Públicos, or “AFIP”) and from the provincial and municipal fiscal authorities, which are not individually significant, and 
which have been reserved based on the best information available as of the date of the issuance of this annual report.  

Pluspetrol Energy S.A. contractual obligations. Pluspetrol and Gas Atacama Generación S.A. (“Gas Atacama”), had reached an 

agreement through which, in case that Pluspetrol could not fulfill its natural gas delivery obligations, it would indemnify Gas 
Atacama. This agreement would come into effect once ratified by the Secretariat of Energy. However, on March 10, 2008, the 
Ministry of Economy and Production issued Resolution No. 127/2008, by which the natural gas export tax withholding rate was 
increased, significantly changing the commercial terms of the aforementioned agreement. Consequently, Pluspetrol informed Gas 
Atacama and the Secretariat of Energy of its intention to terminate the aforementioned agreement. As a result, the parties initiated 
discussions concerning the new regulatory framework, and reached a new agreement pursuant to which Pluspetrol shall compensate 
Gas Atacama for non-delivered volumes. The compensation amounts to U.S.$5.8 million per year (U.S.$2.6 million considering 
YPF’s interest in Pluspetrol), from 2008 until 2014.  

Non-reserved, possible contingencies  
In addition to the probable contingencies described in the preceding paragraphs, we have received several labor, civil, 
commercial and environmental claims which had not been reserved since management, based on the evidence available to date and 
upon the opinion of our external counsel, have considered them to be possible contingencies. The most significant of such 
contingencies are described below.  

Noroeste basin reserves review. The effectiveness after certain specific dates of natural gas export authorizations (related to 
production in the Noroeste basin) granted to us pursuant to Resolution S.E. Nos. 165/99, 576/99, 629/99 and 168/00, issued by the 
Argentine Secretariat of Energy, is subject to an analysis by the Argentine Secretariat of Energy to determine whether sufficient 
additional natural gas reserves have been discovered or developed by us in the Noroeste basin. The result of this ongoing review is 
uncertain and may have an adverse impact upon the execution of the export gas sales agreements related to such export authorizations, 
and may imply significant costs and liabilities for us. We have submitted to the Argentine Secretariat of Energy documentation in 
order to allow for the continuation of the authorized exports in accordance with Resolutions SE No. 629/1999, 565/1999, and 
576/1999 (the “Export Permits”) from the Noroeste basin. These Export Permits relate to the long-term natural gas export contracts 
with Gas Atacama Generación S.A., Empresa Eléctrica del Norte Grande S.A. and Electroandina S.A. (collectively, the “Clients”), 
involving volumes of 900,000 m3/day, 600,000 m3/day and 1,750,000 m3/day, respectively. We have not yet received a response 
from the Argentine Secretariat of Energy. However, on March 29, 2007, an internal memorandum of the technical sector of the 
Argentine Secretariat of Energy addressed this file and concluded, without resolving the question that we have not included the 
necessary reserves to continue with the Export Permits. The file is currently awaiting decision from the Argentine Secretariat of 
Energy. If the Argentine Secretariat of Energy were to determine that the reserves are not sufficient to continue to comply with our 
export commitments and other commitments, it could declare the expiration or suspension of one or more of the Export Permits, 
which would have a direct impact on the export contracts, to the injury of the Clients. In the case in which it were determined that we 
did not act as a prudent and diligent operator and/or did not have sufficient reserves, we could be responsible for the damages that this 
situation causes to the Clients.  

104 

 
  
New Jersey claims. On December 13, 2005, the New Jersey Department of Environmental Protection (the “DEP”) and the New 

Jersey Spill Compensation Fund filed a claim with a New Jersey court against Occidental Chemical Corporation, Tierra, Maxus, 
Repsol YPF, YPF, YPF Holdings and CLH Holdings. The plaintiffs are claiming economic compensation in an undetermined amount 
and punitive damages as a consequence of environmental damages, as well as the costs and fees associated with this proceeding, based 
on alleged violations of the Spill Compensation and Control Act, the Water Pollution Control Act and common law claims relating to 
a facility allegedly operated by the defendants and located in Newark, New Jersey that allegedly impacted the Passaic River and 
Newark Bay. DEP filed its Second Amended Complaint in April 2008; YPF’s motion to dismiss for lack of personal jurisdiction was 
denied in September 2008. The decision was affirmed by the Court of Appeals following an appeal from YPF. Notwithstanding the 
above, the Court denied the plaintiffs’ motion to bar third party practice and allowed defendants to file third-party claims. Third-party 
claims against approximately 300 companies and governmental entities (including certain municipalities) which could have 
responsibility in connection with the claim were filed by Tierra and Maxus in February 2009. See “—YPF Holdings.”  

Patagonian Association of Land-Owners claims. On August 21, 2003, the Patagonian Association of Land-Owners 
(“ASSUPA”) sued the companies operating production concessions and exploration permits in the Neuquina basin, including us, 
claiming for the remediation of the general environmental damage purportedly caused in the execution of such activities or the 
establishment of an environmental restoration fund, and the implementation of measures to prevent environmental damages in the 
future. The total amount claimed against all companies is more than U.S.$547.6 million. The plaintiff requested that the Argentine 
government (Secretariat of Energy), the Federal Environmental Council (Consejo Federal de Medio Ambiente), the provinces of 
Buenos Aires, La Pampa, Neuquén, Río Negro and Mendoza and the National Ombudsman 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 Argentine Supreme Court. Once the complaint was 
notified, we and the other defendants filed a motion to dismiss for failure of the plaintiff to state a claim upon which relief may be 
granted. The court granted the motion, and the plaintiff had to file a supplementary complaint. We requested that the claim be rejected 
because the defects of the complaint indicated by the Argentine Supreme Court have not been corrected, but such request was denied. 
However, we have also requested its rejection for other reasons, and impleaded the Argentine government, due to its obligation to 
indemnify us against any liability and hold us harmless for events and claims arising prior to January 1, 1991, according to Law 
No. 24,145 and Decree 546/1993. On February 23, 2009, the Argentine Supreme Court ordered that certain provinces, the Argentine 
government and the Federal Environmental Council be summoned. Therefore, pending issues were deferred until the impleaded 
parties appear before the court.  

Dock Sud claim. We have been sued in the following environmental lawsuits that have been filed by residents living near Dock 
Sud, province of Buenos Aires: (i) “Mendoza, Beatriz against National State et al.,” a lawsuit before the Argentine Supreme Court, in 
which the Argentine government, the province of Buenos Aires, the City of Buenos Aires, 14 municipalities and 44 companies 
(including us) were sued. The plaintiffs have requested unspecified compensation for collective environmental damage to the Matanza 
and Riachuelo river basins and for physical and property damage, which they claim to have suffered. The Argentine Supreme Court 
declared itself legally competent to settle only the conflict related to the collective environmental damages, including prevention of 
future pollution, remediation of environmental damages already caused and monetary compensation for irreparable environmental 
damages, and has requested that the defendants submit specific reports. In particular, it has requested that the Argentine government, 
the province of Buenos Aires, the City of Buenos Aires and the Federal Environmental Council submit a plan with environmental 
objectives. We answered the complaint and requested the impleading of the Argentine government, based on its obligation to 
indemnify us against any liability and hold us harmless for events and claims previous to January 1, 1991, according to Law 
No. 24,145 and Decree No. 546/1993. In July 2008, the Argentine Supreme Court decided that the Basin Authority (Law 26,168) will 
be in charge of performing a remediation plan as well as of taking preventive measures in the area. The National State as well as the 
Province and City of Buenos Aires will be responsible for the performance of these measures. It also declared the exclusive 
competence of the First Instance Federal Court in Quilmes to hear any claims or disputes arising out of the remediation plan or the 
preventive measures and determined that any future action seeking the environmental remediation of the basin will be dismissed (litis 
pendentia). Additionally, the Argentine Supreme Court declared that it will determine whether and how much liability is to be borne 
by the parties involved; (ii) “Cicero, María Cristina against Antivari S.A.C.I. et al. for damages” in which the plaintiffs, who are 
residents of Villa Inflamable, Dock Sud, also demand the environmental remediation of Dock Sud and Ps.33 million in compensation 
for physical and property damages against many companies that have operations there, including us. We answered the complaint by 
requesting its rejection and asked the citation of the Argentine government, due to its obligation to indemnify us against any liability 
and hold us harmless for events and claims previous to January 1, 1991, according to Law No. 24,145 and Decree No. 546/1993.  

La Plata refinery environmental claims. On June 6, 2007, we were served with a complaint in which nine residents of the 
vicinity of the La Plata refinery request (i) the cessation of contamination and other harms they claim are attributable to the refinery 
and (ii) the cleanup of the adjacent canals, Río Santiago and Río de la Plata (water, soils and aquifers, including within the refinery), 
or, if cleanup is impossible, compensation for environmental and personal damages. The plaintiffs have also requested physical and 
property damages of approximately Ps.51.5 million, or an amount to be determined from evidence produced in discovery. We believe 
that most damages that are alleged by the plaintiffs, if proven, may be attributable to events that occurred prior to YPF’s privatization 
and would therefore be the responsibility of the Argentine government in accordance with the Privatization Law of YPF. 

105 

 
Notwithstanding the aforesaid, there is the possibility a judgment could order us to meet the expenses of remedying these liabilities, in 
which case we could ask the Argentine government to reimburse the remediation expenses for liabilities existing prior to January 1, 
1991 pursuant to Law 24,145. In addition, we believe that this claim partially overlaps with the request made by a group of neighbors 
of the La Plata refinery on June 29, 1999, mentioned in preceding paragraphs. Accordingly, we consider that the cases will need to be 
partially consolidated to the extent that the claims overlap. We answered the complaint by requesting its rejection and asked for the 
citation of the Argentine government, due to its obligation to indemnify us against any liability and hold us harmless for events and 
claims previous to January 1, 1991, according to Law No. 24,145 and Decree No. 546/1993. Additionally, we believe that any 
contamination that may exist could be attributable to numerous sources, including dumping of refuse over many years by other 
industrial facilities and by ships.  

Additionally, we are aware of an action in which we have not yet been served, in which the plaintiff requests the cessation of 

contamination and the cleanup of the canals adjacent to the La Plata refinery, in Río Santiago, and other sectors near the coast 
(removal of mud, drainage of wetlands, restoration of biodiversity, among other things), and, if such sanitation is not practicable, 
compensation of Ps.500 million or an amount to be determined from evidence produced in discovery. We believe that this claim 
partially overlaps with the requests made by a group of neighbors of the La Plata refinery on June 29, 1999 and with the complaint 
served on June 6, 2007, mentioned in preceding paragraphs. Accordingly, we consider that if we are served in this proceeding or any 
other proceeding related to the same subject matters, the cases will need to be consolidated to the extent that the claims overlap. With 
respect to claims that would not be included in the previous proceedings, for the time being we are unable to estimate the prospects of 
such claims. Additionally, we believe that most of the damages that do not overlap with the aforementioned claims may be attributable 
to events that occurred prior to YPF’s privatization and could therefore be the responsibility of the Argentine government in 
accordance with the Privatization Law concerning YPF.  

Sale of Electricidad Argentina S.A. and Empresa Distribuidora y Comercializadora Norte S.A. to EDF International S.A. 

(“EDF”). In 2002 EDF initiated an international arbitration proceeding under the Arbitration Regulations of the International 
Chamber of Commerce (“ICC”) against Endesa Internacional S.A. and YPF. EDF sought a payment of U.S.$69 million from YPF, 
which was subsequently increased to U.S.$103 million plus interests, based on dubious reasons, in connection with the sale of 
Electricidad Argentina S.A., parent company of Edenor S.A. EDF claimed that it was entitled to an adjustment in the purchase price it 
paid under the stock purchase agreement, pursuant to which such price would be reviewed upon the occurrence of changes in the 
exchange rate of the Argentine peso occurred prior to December 31, 2001. EDF considered that this had happened. On October 22, 
2007, the Arbitral Court issued a final arbitral award in which EDF’s claim and the defendants’ counterclaim were partially accepted. 
Consequently, the final arbitral award imposed on YPF the payment of U.S.$28.9 million plus interests and judicial expenses. YPF 
and EDF challenged the arbitral decision before the Argentine justice and on April 22, 2008, the Court of Appeals on Commercial 
Matters declared that the appeal filed by YPF has suspension effects on the arbitral decision. Nevertheless, EDF sought the 
enforcement of the arbitral decision before the District Court of the State of Delaware, United States. The mentioned enforcement was 
rejected by the First Instance Court.  

However, the U.S. Court of Appeals partially overturned such decision and ordered that proceedings be suspended until the 

appeals for annulment filed in Argentina have concluded, as YPF had requested. In addition, YPF has been notified of an action filed 
by EDF in Paris, France, also seeking enforcement of the award. On December 9, 2009, the Court of Appeals on Commercial Matters 
handed down a judgment on the parties’ appeals in which it annulled the arbitration decision that condemned Endesa Internacional 
S.A. and YPF to pay compensation for damages to EDF. It likewise annulled the decision which condemned EDF to pay 
compensation to Endesa Internacional S.A. and YPF. On February 8, 2010, YPF was notified that EDF has filed an extraordinary 
appeal against the aforementioned court’s judgment. The Supreme Court has rejected EDF’s extraordinary appeal and, consequently, 
EDF has presented a complaint appeal. In light of the above, our management has reassesed as possible the outcome of this claim, and 
consequently we have recorded a recovery under the item “Other income/(expense), net” in our income statement for the year ended 
December 31, 2009.  

Concessions on Hydrocarbon bearing zones – Provincial claims. We have been notified of Resolution 433/08 issued by the 

Ministry of Production, Hydrocarbon Department of the Río Negro Province concerning compliance with certain obligations by 
exploitation concessionaires in the hydrocarbon bearing zones of Barranca de los Loros, Bajo del Piche, El Medanito and Los 
Caldenes, all located in Río Negro Province. This resolution asserts that we, among others, in our capacity as a concessionaire, are 
liable for failing to meet certain concession and environmental obligations. If found liable, we could be at risk of termination of these 
concession contracts. In light of the above, and consistent with provisions of the Hydrocarbons Law, we were requested to submit a 
response.  

The Hydrocarbons Law grants the concessionaire and/or licensee the right, prior to termination based upon contractual 
provisions, to cure a contractual breach within a certain period of time after receiving notice thereof. Accordingly, on May 29, 2008, 
we filed a request for nullification of Resolution 433/08, since this resolution failed to grant us this right. Additionally, on June 13, 
2008, we submitted a response denying the charges against us and on November 12, 2008, the Ministry of Production ordered the 
initiation of the evidence production period. On November 28, 2008, we filed a writ requesting the production of certain evidence and 
the appointment of our technical expert. As of the date of this report, we have argued certain aspects related to the production of 
evidence. On May 12, 2009, we were notified of the issuance of Resolution No. 31/09 dated March 13, 2009 by the Ministry of 

106 

 
Production, Hydrocarbon Department of the Río Negro Province, which ordered an extension of the evidence production period in this 
case. On December 1, 2009, we presented the requested documentary evidence, while stating that the resolution of our claims related 
to certain aspects related to the production of evidence are still pending.  

Claims related to the gas market and others. In addition to the claims described under “—Alleged defaults under natural gas 

supply contracts”, we are involved in the following proceedings also related to the restrictions imposed by the Argentine government 
in the natural gas market:  

•  

•  

•  

Arbitration with Transportadora de Gas del Mercosur S.A. (TGM). YPF was notified by the International Chamber of 
Commerce (ICC) of an arbitration brought by TGM against YPF claiming unpaid and outstanding payments in an 
approximate amount of U.S.$10 million, in connection with the transportation fee established in the natural gas 
transportation contract entered into in September 1998 between YPF and TGM, associated with the natural gas export 
contract entered into by YPF, AESU and Companhia de Gás do Estado do Río Grande do Sul (Sulgás), referred below. 
See “—Non-reserved, remote contingencies—Arbitration with AES Uruguaiana Empreendimentos S.A. (AESU), 
Companhia de Gás do Estado do Río Grande do Sul (Sulgás) and Transportadora de Gas del Mercosur S.A. (TGM).” 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 Sulgás of the natural gas export 
contract discussed below.  
On July 10, 2009, TGM increased the amount of its claim to approximately U.S.$17.3 million and claimed an additional 
amount of approximately U.S.$366.4 million for lost profits, a claim for which we believe YPF should not be responsible. 
YPF rejected TGM’s arguments. The Arbitration Tribunal has been constituted. On April 20, 2010, the parties agreed on 
the Terms of Reference in coordination with the Arbitration Tribunal. On June 10, 2010, YPF submitted its arguments on 
procedural grounds before the Arbitration Tribunal and requested the Arbitration Tribunal to determine that it was not 
competent to hear the claim. In case such motion is rejected, YPF has requested the Arbitration Tribunal to suspend this 
arbitration until the ongoing arbitration with TGM, AESU and Sulgás is solved.  
On April 6, 2009, YPF registered a request for arbitration at the ICC against TGM, AESU and Sulgás, seeking an award 
declaring the termination of the gas transportation contract with TGM as a result of the termination of the natural gas 
export contract with AESU and Sulgás by such parties. On the same date, YPF was notified by the ICC of an arbitration 
brought against it by AESU and Sulgás. See “—Non-reserved, remote contingencies—Arbitration with AES Uruguaiana 
Empreendimentos S.A. (AESU), Companhia de Gás do Estado do Río Grande do Sul (Sulgás) and Transportadora de Gas 
del Mercosur S.A. (TGM),” below. YPF has requested that the three proceedings be combined.  
Litigation with 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 for the transport of natural gas in 
connection with the natural gas export contract entered with AESU and other parties. The complaint is based on the 
termination of the referenced natural gas export contract and the legal impossibility of assigning the transportation 
contract to other shippers because of certain changes in law in effect since 2002; as a second order matter, the legal 
impossibility for TGN to render the transportation service on a firm basis because of certain changes in law in effect since 
2004; and as a third order matter, the Teoría de la Imprevisión (hardship provision under Article 1198 of the Argentine 
Civil Code) available under Argentine law when extraordinary events render a party’s obligations excessively 
burdensome.  

CNDC investigation. On November 17, 2003, the CNDC requested explanations, within the framework of an official 
investigation pursuant to Art. 29 of the Antitrust Protection Law, from a group of almost 30 natural gas production 
companies, including us, with respect to the following items: (i) the inclusion of clauses purportedly restraining trade in 
natural gas purchase/sale contracts and (ii) gas imports from Bolivia, in particular (a) expired contracts 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, we submitted explanations in 
accordance with Art. 29 of the Antitrust Protection 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, we received a notification of resolution dated December 2, 2005, whereby the CNDC (i) rejected the 
“non bis in idem” petition filed by us, 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 preliminary opening of the proceedings be 
undertaken pursuant to the provisions of Section 30 of Law 25,156. On January 15, 2007, the CNDC charged us and eight 
other producers with violations of Law 25,156. We have 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 have presented evidence in support 
of our position. On June 22, 2007, without acknowledging any conduct in violation of the Antitrust Protection Law, we 
filed with the CNDC a commitment according to Article 36 of the Antitrust Protection Law requesting that the CNDC 
approve the commitment, suspend the investigation and dismiss the proceedings. We are still awaiting a formal response. 
On December 14, 2007, the CNDC elevated the investigation to the Court of Appeals.  

107 

 
  
•  

•  

In addition, we are subject to other claims before the CNDC which are related to alleged price discrimination in the sale of 
fuels. Our management, based on the evidence available to date and upon the opinion of our external counsel, has 
considered them to be possible contingencies.  
Users and Consumers’ Association claim. The Users and Consumers’ Association (Unión de Usuarios y Consumidores) 
claimed (originally against Repsol YPF before extending its claim to YPF) the reimbursement of allegedly excessive 
prices charged to bottled LPG consumers between 1993 and 2001. The claim is for a sum of Ps.91.2 million for the period 
1993 to 1997 (this sum, in current pesos, would amount to approximately Ps.304 million), together with an undetermined 
amount for the period 1997 to 2001. We invoked the statute of limitations, since the applicable two-year statute of 
limitation had already elapsed. A ruling is pending on the applicability of the statute of limitations. Notwithstanding the 
above, the evidence production period commenced on August 6, 2009.  
Alleged defaults under natural gas contracts – Mega. Mega has claimed compensation from us for failure to deliver 
natural gas under the contract between us and Mega. We invoked that natural gas deliveries to Mega pursuant to the 
contract were affected by the Argentine government’s interference. Consequently, we believe that we are not liable for 
such natural gas delivery deficiencies pursuant to the doctrine of “force majeure”.  

Non-reserved, remote contingencies  
Our management, in consultation with our external counsel, believes that the following contingencies, while individually 

significant, are remote:  

Congressional request for investigation to CNDC. On November 7, 2003, certain former members of the Argentine Congress, 

Arturo Lafalla, Ricardo Falu and others, filed with the CNDC a complaint against us for abuse of a dominant position in the bulk LPG 
market during 2002 and part of 2003. The alleged conduct consisted of selling bulk LPG in the domestic market at prices higher than 
the export price, thereby restricting the availability of bulk LPG in the domestic market. On December 15, 2003, the CNDC decided to 
forward the complaint to us, and requested explanations under Art. 29 of the Antitrust Protection Law. On January 21, 2004, we 
submitted explanations in accordance with Art. 29 of the Antitrust Protection Law, contending that no antitrust violations had been 
committed. At this point, the CNDC may accept our explanations or begin a criminal investigation. We contend that we did not restrict 
LPG supply in the domestic market during the relevant period, that during this period all domestic demand for LPG could have been 
supplied by our competitors and that therefore our market share could not be deemed a dominant position. On September 2, 2008, the 
CNDC issued Note No. 1131/08 requesting information in relation to the prices in the internal and external markets corresponding to 
the years 2000-2008. On October 7, 2008, we presented the information. On December 10, 2008, the CNDC requested us to file the 
LPG export contracts signed during the years 2001-2004 as well as to explain the evolution of the prices in the internal and external 
markets of propane and butane during the March to December period in the years 2001-2004. On December 16, 2008, we presented 
the requested information. Having filed the requested information, we have become aware that the CNDC has issued an opinion 
suggesting that the proceedings be dismissed. However, the matter is still pending before the Secretary of Domestic Commerce.  

Pursuant to the provisions of Resolution No. 189/99, referred to above, certain third parties have claimed compensation for 

alleged damages suffered by them as a consequence of our sanctioned conduct. We have denied these claims and presented our 
defenses.  

Other export tax disputes. Between 2006 and 2009, the Customs General Administrations in Neuquén, Comodoro Rivadavia 
and Puerto Deseado informed us that certain summary proceedings had been brought against us based on alleged formal misstatements 
on forward oil deliveries (future commitments of crude oil deliveries) in the loading permits submitted before these agencies. In 
December 2008, the Customs General Administration of Neuquén rejected our arguments and issued a resolution against us. We will 
appeal before the National Fiscal Court. Although our management, based on the opinion of legal counsel, believes the claim has no 
legal basis, the potential fines imposed could be substantial.  

Mendoza royalties dispute. Following certain claims from the province of Mendoza that the international market price be used 
in the calculation of royalties relating to internal market transactions based on its interpretation of Section 6 of Law No. 25,561, we 
commenced an administrative proceeding. Our request is currently pending. Additionally, YPF filed a declaratory action with the 
Argentine Supreme Court, with application for an injunction to declare unconstitutional the interpretation that the province of 
Mendoza applies to Section 6 of Law No. 25,561. On April 7, 2009, we were notified that the Argentine Supreme Court declared itself 
competent to hear the case brought by YPF, and issued a preliminary injunction to restrain the province of Mendoza from applying the 
international market price in calculating the royalties payable by YPF. The final resolution of this case is still pending.  

Arbitration with AES Uruguaiana Empreendimentos S.A. (AESU), Companhia de Gás do Estado do Río Grande do Sul (Sulgás) 

and Transportadora de Gas del Mercosur S.A. (TGM). On April 6, 2009, YPF was notified by the ICC of an arbitration brought 
against it by AESU and Sulgás claiming damages in an amount of approximately U.S.$1,052 million, which includes damages for the 
matter described above with respect to AESU, in connection with YPF’s alleged liability resulting from the termination by AESU and 
Sulgás of the natural gas export contract entered into in September 1998. See “—Alleged defaults under natural gas supply contracts” 

108 

 
above. YPF denies all liability arising from such termination. Moreover, YPF believes that AESU’s damages assessment is far beyond 
any reasonable assessment, since it exceeds six-fold the maximum aggregate deliver-or-pay penalties that would have accrued in the 
event that YPF would breached its delivery obligations for the maximum daily quantity through the expiration of the term of the 
natural gas export contract. In addition, more than 90% of AESU’s damages assessment relates to alleged loss of profits that may be 
strongly challenged on the basis that prior to the termination of the natural gas export contract, AESU voluntarily terminated all of its 
long term power purchase contracts. Furthermore, on April 6, 2009, YPF registered a request for arbitration against AESU, Sulgás and 
TGM at the ICC seeking a declaration from the arbitral tribunal that, among other things, AESU and Sulgás have repudiated and 
unilaterally and illegally terminated the natural gas export contract entered into in September 1998 and declaring AESU and Sulgás 
liable for any damages suffered by the parties because of such termination, including but not limited to the damages resulting from the 
termination of the natural gas transportation contracts associated with the natural gas export contract. See “—Arbitration with 
Transportadora de Gas del Mercosur S.A. (TGM).”  

The Arbitration Tribunal has been constituted in both arbitration proceedings. However, on December 30, 2009, YPF opposed 

to the designation of the president of both Arbitral Tribunals. The president of these Arbitral Tribunals resigned on February 12, 2010 
and a new president was appointed. YPF opposed to the designation of the new president of both Arbitral Tribunals on May 26, 2010. 
The president of these Arbitral Tribunals resigned on June 10, 2010 and a new president is to be appointed.  

Proceedings related to foreign currency proceeds. On December 9, 2002, we filed a declaratory judgment action (Acción 

Declarativa de Certeza) before an Argentine federal court requesting clarification as to the uncertainty generated by opinions and 
statements of several organizations providing official advice that the right of the hydrocarbon industry to freely dispose of up to 70% 
of foreign currency proceeds from exports of hydrocarbons products and byproducts, as provided by Executive Decree No. 1,589/89, 
had been implicitly abolished by the new exchange regime established by Executive Decree No. 1,606/01. On December 9, 2002, a 
federal judge issued an injunction ordering the Argentine government, the Central Bank and the Ministry of the Economy to refrain 
from interfering with our access to and use of 70% of the foreign exchange proceeds from our hydrocarbon exports. Following the 
enactment of Decree No. 2,703/02 in December 2002, we expanded the scope of the declaratory judgment action before the federal 
court to clear any doubts and uncertainty arising after the enactment of this decree. See “Item 4. Information on the Company—
Regulatory Framework and Relationship with the Argentine Government—Repatriation of Foreign Currency”. On December 1, 2003, 
the National Administrative Court of Appeals decided that the issuance of Decree No. 2,703/02, which allows companies in the oil 
and gas sector to keep abroad up to 70% of the export proceeds, rendered the injunction unnecessary. Nevertheless, the Court of 
Appeals’ decision was silent with respect to the availability of the exemption to convert proceeds from export operations carried out 
by oil and gas companies into domestic currency prior to the issuance of Decree No. 2,703/02.  

On October 12, 2007, we were notified of the initiation of an administrative summary proceeding for alleged late repatriation of 

foreign currency proceeds, and the failure to repatriate the remaining 70%, in connection with some hydrocarbon export transactions 
made in 2002 (during the period between the issuance of Decree No. 1,606/01 and the issuance of Decree No. 2,703/02). Nevertheless, 
a final and unchallenged judicial judgment issued by a First Instance Court in Criminal Economic Matters in a similar administrative 
summary proceeding against a different company for alleged violation of the criminal exchange law (lack of repatriation of 70% of 
foreign currency proceeds) regarding export transactions made in 2002 resolved the matter in favor of that company based on well-
founded arguments that were not challenged by the prosecutor. In addition, the Office of the General Prosecutor of Argentina has 
issued an opinion in a similar administrative summary proceeding involving another oil company stating that no criminal law 
violations existed in that case due to the lack of willful misconduct and the existence of differing regulations that created uncertainty 
as to the scope of certain obligations, and stating that the proceeding should be dismissed. On April 30, 2009, in similar administrative 
proceedings involving another oil company, the National Administrative Court of Appeals resolved the matter in favor of that 
company, on the basis that the free disposal regime of up to 70% of export proceeds was in force during 2002, upon the publication of 
Decree No. 1638/01 on December 12, 2001. Extraordinary appeals filed by the Argentine government and the Central Bank have been 
rejected. Consequently, YPF considers that the administrative summary proceeding against YPF is unlikely to be successful.  

Additional information  
On August 11, 2006, we received Note SE No. 1009 (the “Note”) from the Argentine Secretariat of Energy, which reviewed the 

progress of reserves in the Ramos Area in the Noroeste basin, in relation to the export authorization granted by Resolution S.E. 
No. 169/97 (the “Export Authorization”). The Export Authorization concerns the long-term natural gas export contract between us and 
Gas Atacama, for a maximum daily volume of 530,000 m3/day. The Note stated that as a result of the decrease in natural gas reserves 
supporting the Export Authorization, the domestic market supply was at risk. The Note preventively provided that the maximum 
natural gas daily volumes authorized to be exported under the Export Authorization were to be reduced by 20%, affecting the export 
contract. We filed an answer to the Note on September 15, 2006 stating our allegations and defenses.

YPF Holdings  

The following is a brief description of certain environmental and other liabilities related to YPF Holdings Inc., a Delaware 

corporation.  

In connection with the sale of Maxus’ former chemical subsidiary, Chemicals, to 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 the 
Closing Date, including certain environmental liabilities relating to certain chemical plants and waste disposal sites used by Chemicals 
prior to the Closing Date. See “Item 4. Information on the Company—Environmental Matters—YPF Holdings—Operations in the 
United States”.  

As of December 31, 2009, YPF Holdings’ reserves for environmental and other contingencies totaled approximately Ps.531 

million. YPF Holdings management believes it has adequately reserved for all environmental and other contingencies that are 
probable and can be reasonably estimated based on information available as of such time; however, many such contingencies are 
subject to significant uncertainties, including the completion of ongoing studies, the discovery of new facts, and the issuance of orders 
by regulatory authorities, which could result in material additions to such reserves in the future. It is possible that additional claims 
will be made, and additional information about new or existing claims (such as results of ongoing investigations, the issuance of court 
decisions or the signing of settlement agreements) is likely to develop over time. YPF Holdings’ reserves for the environmental and 
other contingencies described below are based solely on currently available information and as a result, YPF Holdings, Maxus and 
Tierra may have to incur costs that may be material, in addition to the reserves already taken.  

In the following discussion concerning plant sites and third party sites, references to YPF Holdings include, as appropriate and 
solely for ease of reference, references to Maxus and Tierra. As indicated above, Tierra is also a subsidiary of YPF Holdings and has 
assumed certain of Maxus’ obligations.  

Newark, New Jersey. A consent decree, previously agreed upon by the U.S. Environmental Protection Agency (the “EPA”), the 
New Jersey Department of Environmental Protection (the “DEP”) and Occidental, as successor to Chemicals, was entered in 1990 by 
the United States District Court of New Jersey for Chemicals’ former Newark, New Jersey agricultural chemicals plant. The approved 
interim remedy has been completed and paid for by Tierra pursuant to the above described indemnification agreement with 
Occidental. Operations and maintenance of the constructed remedy are ongoing, and as of December 31, 2009, YPF Holdings has 
reserved approximately Ps.53 million in connection with such activities.  

Passaic River/Newark Bay, New Jersey. Maxus, acting on behalf of Occidental, negotiated an agreement with the EPA under 
which Tierra has conducted further testing and studies to characterize contaminated sediment and biota in a six-mile portion of the 
Passaic River near the Newark, New Jersey plant site described above. While some work remains, these studies were substantially 
completed in 2005. In addition, the EPA and other agencies are addressing the lower 17-mile portion of the Passaic River (including 
the six-mile portion already studied) in a joint federal, state, local and private sector cooperative effort designated as the Lower 
Passaic River Restoration Project (“PRRP”). Tierra, along with certain other entities, has agreed to participate in and fund a remedial 
investigation and feasibility study (“RIFS”) in connection with the PRRP. The parties are discussing the possibility of further work 
with the EPA. The entities that have agreed to fund the RIFS have negotiated allocations of RIFS costs among themselves based on a 
number of considerations.  

Tierra, acting on behalf of Occidental, is also performing and funding a separate RIFS to characterize sediment contamination 

and evaluate remedial alternatives in Newark Bay and portions of the Hackensack River, the Arthur Kill, and the Kill van Kull 
pursuant to a 2004 administrative order on consent with EPA. The EPA has issued General Notice Letters to a series of additional 
parties concerning the contamination of Newark Bay.  

In December 2005, the DEP issued a directive to Tierra, Maxus and Occidental directing said parties to pay the State of New 

Jersey’s costs of developing a Source Control Dredge Plan focused on allegedly dioxin-contaminated sediment in the lower six-mile 
portion of the Passaic River described above. The development of this Plan was estimated by the DEP to cost approximately U.S.$2.3 
million. The DEP has advised the recipients that they are not required to respond to the directive until otherwise notified. Also in 
December 2005, the DEP and the New Jersey Spill Compensation Fund sued YPF Holdings, Tierra, Maxus and other affiliates, as 
well as Occidental, in connection with dioxin contamination allegedly emanating from Chemicals’ former Newark plant and 
contaminating the lower 17-mile portion of the Passaic River, Newark Bay, other nearby waterways and surrounding areas. The 
defendants have made responsive pleadings and/or filings. In March 2008, the court denied motions to dismiss for failure to state a 
claim by Occidental Chemical Corporation, and by Tierra and Maxus. DEP filed its Second Amended Complaint in April 2008; YPF’s 
motion to dismiss for lack of personal jurisdiction was denied in September 2008. The decision was affirmed by the Court of Appeals 
following an appeal by YPF. The Court denied the plaintiffs’ motion to bar third party practice and allowed defendants to file third-
party claims. Third-party claims against approximately 300 companies and governmental entities (including certain municipalities) 
which could have responsibility in connection with the claim were filed by Tierra and Maxus in February 2009. See “—Argentina—
New Jersey Claims.”

In June 2007, EPA released a draft Focused Feasibility Study (“FFS”) that outlines several alternatives for remedial action in the 

lower eight miles of the Passaic River. These range from no action (which would result in comparatively little cost) to extensive 
dredging and capping (which according to the draft FFS, EPA estimated could cost from U.S.$0.9 billion to U.S.$2.3 billion), and are 
all described by EPA as involving proven technologies that could be carried out in the near term, without extensive research. Tierra, in 
conjunction with the other parties of the PRRP group, submitted comments on the draft FFS to EPA, as did a number of other 
interested parties. A revised remedy proposal is expected to be issued during the first quarter of 2011. Tierra plans to respond to any 
further EPA proposal as may be appropriate at that time.  

In August 2007, the National Oceanic Atmospheric Administration (“NOAA”), as one of the Federal Natural Resources 
Trustees (“Trustees”), sent a letter to the parties of the PRRP group, including Tierra 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. The PRRP 
group has declined the NOAA’s request, citing concerns with matters such as the FFS. In January 2008, the NOAA sent a letter to us, 
YPF Holdings, CLH Holdings Inc. and other entities designating each as a potentially responsible party (“PRP”), all of which have 
denied being a PRP. In November 2008, Occidental and Tierra entered into an agreement with the Trustees to fund a portion of the 
Trustees’ past costs and conduct certain assessment activities during 2009. A group of approximately 20 other parties has also entered 
into a similar agreement with the Trustees. In November 2009, Tierra declined to extend this agreement for one additional year, citing 
concerns arising from the Passaic River litigation.  

In June 2008, the EPA, Occidental, and Tierra entered into an Administrative Order on Consent (“AOC”), pursuant to which 

Tierra (on behalf of Occidental) will undertake the removal of sediment from a portion of the Passaic River in the vicinity of 
Chemicals’ former Newark, New Jersey facility described above. This action will result in the removal of approximately 200,000 
cubic yards of sediment, which will be carried out in two phases. The field work on the first phase, which will encompass the removal 
of 40,000 cubic yards, is scheduled to begin in 2010 and is expected to be completed approximately nine months later. The first phase 
of clean up is estimated to cost approximately U.S.$44.7 million. The second phase, which will encompass the removal of 
approximately 160,000 cubic yards of sediment, will be completed on a different schedule. Pursuant to the AOC, the EPA has required 
the provision of financial assurance in the amount of U.S.$80 million for the performance of the removal work through a trust fund. 
As of the date of this report, U.S.$22 million has been contributed to the fund; an additional U.S.$10 million must be contributed 
every six months until a total of U.S.$80 million has been deposited into the fund. The total amount of required financial assurance 
may be decreased or increased over time if the anticipated cost of completing the removal work contemplated by the AOC changes. 
During the removal work, certain contaminants not produced by the former Chemicals plant, such as PCBs and mercury, will be 
removed along with dioxin. YPF Holdings may seek cost recovery from the parties responsible for such contamination; however, at 
this time it is not possible to make any predictions regarding the likelihood of success or the funds potentially recoverable in a cost-
recovery action. The removal work required pursuant to the AOC will be conducted concurrently with and in addition to the other 
investigations and remedial actions described above, including those undertaken in connection with the FFS concerning the lower 
eight miles of the Passaic River, the RIFS addressing the lower 17-mile portion of the Passaic River, and the RIFS relating to 
contamination in Newark Bay, portions of the Hackensack River, the Arthur Kill and the Kill van Kull.  

As of December 31, 2009, YPF Holdings has reserved approximately Ps.248 million in connection with the foregoing matters 
related to the Passaic River, the Newark Bay and the surrounding area comprising the estimated costs for studies, estimated costs in 
connection with the AOC, and certain other matters related to the Passaic River and Newark Bay. However, it is possible that other 
works, including interim remedial measures, may be ordered. How these matters are resolved, including the development of new 
information, the imposition of natural resource damages or the selection of remedial actions differing from the scenarios we have 
proposed could result in Maxus and Tierra incurring material costs in addition to the amount currently reserved.  

Hudson and Essex Counties, New Jersey. Until the 1970s, Chemicals operated a chromite ore processing plant at Kearny, New 

Jersey (the “Kearny Plant”). Tierra, on behalf of Occidental, is providing financial assurance in the amount of U.S.$20 million for 
performance of the work associated with the issues described below.  

In May 2005, the DEP took two actions in connection with the chrome sites in Hudson and Essex Counties. First, the DEP 
issued a directive to Maxus, Occidental and two other chromium manufacturers (the “Respondents”) directing them to arrange for the 
cleanup of chromite ore residue at three sites in Jersey City and for the conduct of a study by paying the DEP a total of U.S.$19.5 
million. Second, the DEP filed a lawsuit against Occidental and two other entities in state court in Hudson County seeking, among 
other things, cleanup of various sites where chromite ore residue is allegedly located, recovery of past costs incurred by the state at 
such sites (including in excess of U.S.$2.3 million dollars allegedly spent for investigations and studies) and, with respect to certain 
costs at 18 sites, treble damages. The DEP claims that the defendants are jointly and severally liable, without regard to fault, for much 
of the damages alleged. The parties have come to an agreement regarding this matter, pursuant to which Tierra will pay U.S.$5 
million, and will remediate 3 sites, at an estimated cost of U.S.$2.1 million. In addition, in 2008 the DEP approved the construction of 
certain interim remedial measures relating to the Kearny Plant; work on those remedial measures has begun.  

111 

 
Pursuant to a request of the DEP, in the second half of 2006, Tierra and certain other parties tested the sediments in a portion of 

the Hackensack River near the former Kearny Plant. A report of those test results has been submitted to the DEP. The DEP has 
requested additional sampling, and a work plan to conduct such sampling has been prepared and submitted to the DEP for its approval.  

In November 2005, several environmental groups sent a notice of intent to sue the owner of the property adjacent to the former 

Kearny Plant and five other parties, including Tierra, under the Resource Conservation and Recovery Act. The parties have entered 
into an agreement that addresses the concerns of the environmental groups and these groups have agreed, at least for now, not to file 
suit.  

As of December 31, 2009, YPF Holdings has reserved a total of approximately Ps.102 million in connection with the foregoing 
chrome-related matters. Soil action levels for chromium in New Jersey have not been finalized, and the DEP continues to review the 
proposed action levels. The cost of addressing these chrome-related matters could increase significantly depending upon the final soil 
action levels, the DEP’s response to Tierra’s studies and reports and other developments.  

Painesville, Ohio. From about 1912 through 1976, Chemicals operated manufacturing facilities in Painesville, Ohio (the 
“Painesville Works”). The operations there over the years involved several discrete but contiguous plant sites over an area of about 
1,300 acres. The primary area of concern historically has been Chemicals’ former chromite ore processing plant (the “Chrome Plant”). 
The Ohio Environmental Protection Agency (“OEPA”) has approved certain work, including the remediation of specific sites within 
the former Painesville Works area and work associated with development plans (the “Remediation Work”). The Remediation Work 
has begun. As the OEPA approves additional projects for the site of the former Painesville Works, additional amounts may need to be 
reserved. YPF Holdings has reserved a total of approximately Ps.8 million as of December 31, 2009 for its estimated share of the cost 
to perform the remedial investigation and feasibility study, the Remediation Work and other operation and maintenance activities at 
this site.  

Third Party Sites. Pursuant to settlement agreements with the Port of Houston Authority (the “Port”) and other parties, Tierra 

and Maxus are participating (on behalf of Occidental) in the remediation of property adjoining Chemicals’ former Greens Bayou 
facility where dichloro-diphenyl-trichloroethane (“DDT”) and certain other chemicals were manufactured. Additionally, in 2007 the 
parties entered into a settlement with federal and state natural resources trustees in connection with claims for natural resources 
damages. As of December 31, 2009, YPF Holdings has reserved approximately Ps.32 million for its estimated share of the 
remediation and the natural resources damages settlement associated with the Greens Bayou facility. The remediation activities were 
largely finished in 2009, but some minor closure activities, as well as ongoing operations and maintenance, are still in progress.  

In June 2005, the EPA designated Maxus as a PRP at the Milwaukee Solvay Coke & Gas Site in Milwaukee, Wisconsin. The 

basis for this designation is Maxus’ alleged status as the successor to Pickands Mather & Co. and Milwaukee Solvay Coke Co., 
companies that the EPA has asserted are former owners or operators of such site. Preliminary work in connection with the RIFS in 
respect of this site commenced in the second half of 2006. YPF Holdings has reserved approximately Ps.10 million as of 
December 31, 2009 for its estimated share of the costs of the RIFS. Maxus lacks sufficient information to determine additional 
exposure or costs, if any, it might have in respect of this site.  

Maxus is responsible for certain liabilities attributable to Occidental, as successor to Chemicals, in respect of the Malone 
Service Company Superfund Site in Galveston County, Texas. This site is a former waste disposal site where Chemicals is alleged to 
have sent waste products prior to September 1986.  

Chemicals has also been designated as a PRP by the EPA under the Comprehensive Environmental Response, Compensation 
and Liability Act of 1980, as amended (“CERCLA”) with respect to a number of third party sites where hazardous substances from 
Chemicals’ plant operations allegedly were disposed or have come to be located. Numerous PRPs have been named at substantially all 
of these sites. At several of these, Chemicals has no known exposure. At December 31, 2009, YPF Holdings had reserved 
approximately Ps.2 million in connection with its estimated share of costs related to the Milwaukee Solvay Coke & Gas Site, the 
Malone Service Company Superfund Site, and the other sites mentioned in this paragraph.  

“ Agent Orange” and VCM Litigation. In 2002, Occidental sued Maxus and Tierra in state court in Dallas, Texas seeking a 
declaration that Maxus and Tierra have the obligation under the agreement pursuant to which Maxus sold Chemicals to Occidental to 
defend and indemnify Occidental from and against certain historical obligations of Chemicals, including claims related to “Agent 
Orange” and vinyl chloride monomer (VCM), notwithstanding the fact that said agreement contains a 12-year cut-off for defense and 
indemnity obligations with respect to most litigation. Tierra was dismissed as a party, and the matter was tried in May 2006. The trial 
court decided that the 12-year cut-off period did not apply and entered judgment against Maxus. This decision was affirmed by the 
Court of Appeals in February 2008. Maxus’ petition to the Texas Supreme Court for review was denied. This decision will require 
Maxus to accept responsibility for various matters for which it has refused to indemnify Occidental since 1998, which could result in 
the incurrence of costs in addition to YPF Holdings’ current reserves for this matter. This decision will also require Maxus to 
reimburse Occidental for past costs on these matters. In March 2009, Maxus paid U.S.$14.9 million in respect of court costs, interests 
through the end of 2007 and estimates of future costs for which Maxus could become liable under the declaratory judgment. As of 
December 31, 2009, YPF Holdings had reserved approximately Ps.1 million in respect of this matter.  

112 

 
Turtle Bayou Litigation. In March 2005, Maxus agreed to defend Occidental, as successor to Chemicals, in respect of an action 
seeking the contribution of costs for the remediation of the Turtle Bayou waste disposal site in Liberty County, Texas. Judgment was 
entered in this action, and Maxus filed a motion for reconsideration which was partially successful. As a result, the court’s decision 
requires Maxus to pay, on behalf of Occidental, approximately 16% of those costs incurred by one of the plaintiffs. Maxus has 
appealed. As of December, 2009, YPF Holdings has reserved approximately Ps.14 million in respect of this matter.  

YPF Holdings, including its subsidiaries, is a party to various other lawsuits, the outcomes of which are not expected to have a 

material adverse affect on the company’s financial condition. YPF Holdings has established reserves for legal contingencies and 
environmental issues in those situations where a loss is probable and can be reasonably estimated.

Buenos Aires Stock Market  

The Buenos Aires Stock Market is the principal Argentine market for trading the ordinary shares.  

The Buenos Aires Stock Market (Mercado de Valores de Buenos Aires, or “MERVAL”) is the largest stock market in Argentina 

and is affiliated with the BASE. MERVAL is a corporation consisting of 133 shareholders who are the sole individuals or entities 
authorized to trade, either as principals or agents, in the securities listed on the BASE. Trading on the BASE is conducted either 
through the traditional auction system from 11 a.m. to 6 p.m. on trading days, or through the Computer-Assisted Integrated 
Negotiation System (Sistema Integrado de Negociación Asistida por Computación, or “SINAC”). SINAC is a computer trading system 
that permits trading in both debt and equity securities and is accessed by brokers directly from workstations located in their offices. 
Currently, all transactions relating to listed negotiable obligations and listed government securities can be effectuated through SINAC. 
In order to control price volatility, MERVAL imposes a 15-minute suspension on trading when the price of a security registers a 
variation in price between 10% and 15% and between 15% and 20%. Any additional 5% variation in the price of a security will 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 institutional pension funds created under the amendments to the social 
security laws enacted in late 1993.  

Certain information regarding the Argentine stock market is set forth in the table below.

Argentine Securities Market  

The securities market in Argentina is composed of 10 stock exchanges, which are located in the City of Buenos Aires (the 
“BASE”), Bahía Blanca, Corrientes, Córdoba, La Plata, La Rioja, Mendoza, Rosario, Santa Fe, and Tucumán. Five of these exchanges 
(the BASE, Rosario, Córdoba, Mendoza, and Santa Fe) have affiliated stock markets and, accordingly, are authorized to quote 
publicly offered securities. Securities listed on these exchanges include corporate equity and bonds and government securities.  

The BASE, which began operating in 1854, is the principal and longest-established exchange in Argentina. Bonds listed on the 
BASE may simultaneously be listed on the Argentine over-the-counter market (Mercado Abierto Electrónico, or “MAE”), pursuant to 
an agreement between BASE and MAE that stipulates that equity securities are to be traded exclusively on the BASE, while debt 
securities (both public and private) may be traded on both the MAE and the BASE. In addition, through separate agreements with the 
BASE, all of the securities listed on the BASE may be listed and subsequently traded on the Córdoba, Rosario, Mendoza, La Plata and 
Santa Fe exchanges, by virtue of which many transactions originating on these exchanges relate to BASE-listed companies and are 
subsequently settled in Buenos Aires. Although companies may list all of their capital stock on the BASE, controlling shareholders in 
Argentina typically retain the majority of a company’s capital stock, resulting in a relatively small percentage of active trading of the 
companies’ stock by the public on the BASE.

Argentina’s equity markets have historically been composed of individual investors, though in recent years there has been an 

increase in the level of investment by banks and insurance companies in these markets. The participation of Argentine pension funds 
represents an increasing percentage of the BASE market; however, Argentine mutual funds (fondos comunes de inversión) continue to 
have very low participation.  

Regulation of the Argentine securities market  

The Argentine securities market is regulated and overseen by the CNV, pursuant to Law No. 17,811, as amended, which, in 

addition to having created the CNV, governs the regulation of security 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 pension funds and insurance companies are regulated by separate government agencies, whereas financial 
institutions are regulated primarily by the Central Bank.  

In Argentina, debt and equity securities traded on an exchange or the over-the-counter market must, unless otherwise instructed 

by their shareholders, be deposited with Stock Exchange Incorporated (Caja de Valores S.A.), a corporation owned by the BASE, 
MERVAL and certain provincial exchanges. Stock Exchange Incorporated is the central securities depositary of Argentina and 
provides central depositary facilities, as well as acting as a clearinghouse for securities trading and as a transfer and paying agent for 
securities transactions. Additionally, it handles the settlement of securities transactions carried out by the BASE and operates SINAC.  

Despite a change in the legal framework of Argentine securities trading in the early 1990s, which permitted the issuance and 
trading of new financial products in the Argentine capital markets, including commercial paper, new types of corporate bonds and 
futures and options, there is still a relatively low level of regulation of the market for Argentine securities and investors’ activities in 
such markets and enforcement of them has been extremely limited. Because of the limited exposure and regulation in these markets, 
there may be less publicly available information about Argentine companies than is regularly published by or about companies in the 
United States and certain other countries. However, the CNV has taken significant steps to strengthen disclosure and regulatory 
standards for the Argentine securities market, including the issuance of regulations prohibiting insider trading and requiring insiders to 
report on their ownership of securities, with associated penalties for noncompliance.  

In order to improve Argentine securities market regulation, the Argentine government issued Decree No. 677/01 on June 1, 
2001 (the “Transparency Decree”), which provided certain guidelines and provisions relating to capital markets transparency and best 
practices. The Transparency Decree applies to individuals and entities that participate in the public offering of securities, as well as to 
stock exchanges. Among its key provisions, the decree broadens the definition of a “security,” governs the treatment of negotiable 
securities, obligates 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), authorizes market stabilization transactions under certain 
circumstances, governs insider trading, market manipulation and securities fraud and regulates going-private transactions and 
acquisitions of voting shares, including controlling stakes in public companies.  

Before offering securities to the public in Argentina, an issuer must meet certain requirements established by the CNV with 

regard to the issuer’s assets, operating history and management. Only securities approved for a public offering by the CNV may be 
listed on a stock exchange. 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 and various other periodic reports with the CNV and the stock exchange on which their securities are 
listed, as well as to report to the CNV and the relevant stock exchange any event related to the issuer and its shareholders that may 
affect materially the value of the securities traded.  

Money laundering regulations  

Recent modifications to Argentine money laundering regulations have resulted in their application to increasing numbers and 

types of securities transactions.  

Argentine Law No. 25,246 (as amended by Law No. 26,087 and Law 26,119) categorizes money laundering as a crime under 
the Argentine Criminal Code and created the Unidad de Información Financiera (“UIF”), an agency of the Ministry of Justice and 
Human Rights of Argentina responsible for investigating questionable transactions. The Argentine Criminal Code defines money 
laundering as the exchange, transfer, management, sale or any other use of money or other assets obtained through a crime, by a 
person who did not take part in such crime, with the possible result that such original assets (or new asset resulting from such original 
asset) have the appearance of having been obtained through legitimate sources, provided that the aggregate value of the assets 
exceeded Ps.50,000, whether such amount results from one or more connected transactions.  

The money laundering legal framework assigns control and information reporting duties to certain private sector entities, 

including banks, broker-dealers, trading companies and insurance companies, in many cases according to highly general criteria. 
According to the rules of the Guide to Unusual or Questionable Financial and Foreign Exchange Transactions (Guía de Transacciones 
Inusuales o Sospechosas en la Órbita del Sistema Financiero y Cambiario) approved by Resolution No. 2/2002 of the UIF (as 

116 

 
  
amended), such entities have an obligation to notify the UIF of transactions falling into the following general categories: 
(a) investments in securities in amounts significantly exceeding the amounts normally invested by a particular investor, taking the 
business of the investor into account; (b) deposits or back-to-back loans in jurisdictions known as tax havens; (c) requests for asset 
management services where the origin of funds is not certain, is unclear or does not relate to the business of the investor; (d) unusual 
transfers of large amounts of securities or interests; (e) unusual and frequent use of special investment accounts; and (f) frequent 
purchases and sales of securities during the same day for the same amount and volume, when such transactions seem unusual and 
inadequate considering the business of the investor.  

ITEM 10.  
Capital Stock  

Additional Information  

Our capital stock consists of Ps.3,933,127,930, divided into 3,764 Class A shares, 7,624 Class B shares, 65,949 Class C shares 

and 393,235,456 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.  

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 
1,023/06 of the Ministry of Economy and Production, 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. See “Item 4. Information on the Company—History of YPF.”  

The Class A shares held by the Argentine government became eligible for sale in April 1995 upon the effectiveness of 

legislation which permitted the Argentine government to sell such shares. In January 1999, Repsol YPF acquired 52,914,700 Class A 
shares in block (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 at a price of U.S.$44.78 per share (the “Offer”). 
Pursuant to the Offer, in June, 1999, Repsol YPF acquired an additional 82.47% of our outstanding capital stock. On November 4, 
1999, Repsol YPF acquired an additional 0.35%. On June 7, 2000, Repsol YPF announced a tender offer to exchange newly issued 
Repsol YPF’s shares for 2.16% of our Class B, C and D shares held by minority shareholders. Pursuant to the tender offer, and after 
the merger with Astra Compañía Argentina de Petróleo, S.A. (“Astra”) and Repsol Argentina, S.A., Repsol YPF owned 330,551,981 
Class D shares and therefore controlled us through a 99.04% ownership interest until 2008. On February 21, 2008, Petersen Energía 
S.A. (“Petersen Energía”) purchased 58,603,606 of our ADSs, representing 14.9% of our capital stock, from Repsol YPF for 
U.S.$2,235 million (the “Petersen Transaction”). In addition, Repsol YPF granted options to Enrique Eskenazi, Sebastián Eskenazi, 
Ezequiel Eskenazi Storey and Matías Eskenazi Storey, shareholders of Petersen Energía, or to companies that are, directly or 
indirectly, wholly-controlled by any of them to purchase up to an additional 10.1% of our outstanding capital stock within four years 
(the “Petersen Options”). On May 20, 2008, Petersen Energía Inversora S.A. (“PEISA”) exercised an option to purchase shares 
representing 0.1% of our capital stock. Additionally, PEISA launched a tender offer to purchase all of the shares of YPF that were not 
already owned by them at a price of U.S.$49.45 per share or ADS. Repsol YPF, pursuant to its first option agreement with Petersen 
Energía, had stated that it would not tender YPF shares to PEISA. A total of 1,816,879 shares (including Class D shares and ADSs), 
representing approximately 0.462% of our total shares outstanding, were tendered.  

117 

 
  
  
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 Shareholder’s Meeting on April 14, 2010, YPF’s shareholders approved an amendment to YPF’s by-laws which is in the 
process of being registered at the Inspection Board of Legal Entities of the Argentine Republic. Copies of the by-laws, which have 
been filed as described in “Item 19. Exhibits” in this annual report, 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 No. 19,550 (the “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.  

In order to attend the meeting, shareholders must obtain a deposit certificate from a broker or from the depository trust 
company. 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. YPF will issue to each shareholder a deposit certificate required for admission into the 
meeting. Shares certified and registered in the attendance book shall not be disposed of before the meeting is held unless the 
corresponding deposit is cancelled.  

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 to the approval of their management duties or their removal for cause.  

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 close 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 election, performance and remuneration of 
directors and members of the Supervisory Committee. In addition, pursuant to the Transparency Decree, 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.  

118 

 
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 Buenos Aires Stock Exchange, 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 in 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, granted in a special meeting of 
the holders of such shares.  

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 

with the Superintendent of Corporations (Inspección General de Justicia, or IGJ) 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 with the IGJ, 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.  

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.  

119 

 
  
Directors shall hold office from one to three years, as determined by the shareholders’ meetings. Since the shareholders’ general 

ordinary and extraordinary meeting held on April 28, 2009, our Board of Directors is composed of 17 directors and 13 alternates.  

In accordance with our by-laws, the Argentine government, sole holder of Class A shares, is entitled to elect one director and 

one alternate. The current director representative of Class A shares was appointed to serve up to a one-year term.  

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.  

The composition of certain of our Board committees, as well as the roles of certain members thereof, are affected by the 

implementation of the shareholders’ agreement between Repsol YPF and Petersen Energía. See “Item 7. Major Shareholders and 
Related Party Transactions—Shareholders’ Agreement.”  

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 or our by-laws or regulations, and for any damage caused by fraud, abuse 
of authority or gross negligence. Specific duties may be assigned to a director by the by-laws, company regulations, or by resolution of 
the shareholders’ meeting. In such cases, a director’s liability will be determined by reference to the performance of such duties.  

Only shareholders, through a shareholders’ meeting may authorize directors to engage in activities in competition with us. 

Transactions or contracts between directors and us in connection with our activities are permitted to the extent they are performed 
under fair market conditions. Transactions that do not comply with the Argentine 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 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.  

120 

 
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 shareholders at the next shareholders’ meeting.  

We have distributed over 85% of our net income attributable to the years 2001 through 2006 in dividends to our shareholders. 

We have not adopted a formal dividend policy. Any dividend policy adopted will be subject to a number of factors, including our debt 
service requirements, capital expenditure and investment plans, other cash requirements and such other factors as may be deemed 
relevant at the time. In addition, Repsol YPF and Petersen Energía have agreed in the shareholders’ agreement entered into by them in 
connection with the Petersen Transaction to effect the adoption of a dividend policy under which we would distribute 90% of our net 
income as dividends, starting with our net income for 2007. They also agreed to vote in favor of corporate resolutions requiring us to 
distribute a special dividend of U.S.$850 million, which was paid jointly with the ordinary dividends in 2008 and 2009. See “Item 7. 
Major Shareholders and Related Party Transactions—Shareholders’ Agreement.”  

The following table sets forth for the periods and dates indicated, the quarterly dividend payments made by us, expressed in 

pesos.

On April 14, 2010, our shareholder’s meeting approved the creation of a statutory reserve for future dividends in the amount of 
Ps.5,040 million, and empowered the Board of Directors to decide all matters with respect to its distribution. Our Board of Directors 
approved a dividend of Ps.5.50 per share or per ADS, which was paid out of the reserve for future dividends on April 26, 2010.  

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 Argentine GAAP and CNV regulations and approved by a shareholders’ meeting. The Board 
of Directors of a listed Argentine company may declare interim dividends, in which case each member of the Board and of the 
Supervisory Committee is 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 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, an amount equivalent to 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 Directors and Officers”);  
third, an amount is segregated to pay dividends on preferred stock, if any; and  
fourth, the remainder of net income may be distributed as dividends to common shareholders or allocated for voluntary or 
contingent reserves as determined by the shareholders’ meeting.  

•  

•  

•  

Our Board of Directors submits our financial statements for the preceding fiscal year, together with reports thereon by the 
Supervisory Committee and the auditors, 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 approve our yearly financial statements and determine the 
allocation of our net income for such year.  

121 

 
   
 
 
 
 
 
  
  
  
  
  
  
  
  
 
 
 
 
 
 
Under applicable CNV regulations, cash dividends must be paid to shareholders within 30 days of the shareholders’ meeting 

approving such dividends or, in the case in which the shareholders’ meeting delegates the authority to distribute dividends to the 
Board of Directors, within 30 days of the Board of Directors’ meeting approving such dividends. In the case of stock dividends, shares 
are required to be delivered within three months of our 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 Commercial Code, the statute of limitations to the right of any 
shareholder to receive dividends declared by the shareholders’ meeting is three years from the date on which it has been made 
available to the shareholder.  

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 The Bank of New York S.A., 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 Securities 

Act 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.  
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 the Company 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.  

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.  

123 

 
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.” 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.  

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 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) 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;  

(ii) 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;  

(iii) 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  

(iv) 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.  

124 

 
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) 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;  

(ii) 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;  

(iii) 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  

(iv) the net earnings per share of the shares of the Class during the four most recent full fiscal quarters preceding the 

announcement of the Related Party Transaction multiplied by the higher of the (A) the price/earnings ratio during such period 
for the shares of the Class and (B) the highest price/earnings ratio for 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.  

Exchange Controls  

See “Item 3. Key Information—Exchange Controls” for information on the monetary and currency exchange control restrictions 

in effect in Argentina.  

Taxation  
Argentine Tax Considerations  

The following discussion is a summary of the material Argentine tax considerations relating to the purchase, ownership and 

disposition of our Class D shares or ADSs.  

Dividends tax  

Dividends paid on our Class D shares or ADSs, whether in cash, property or other equity securities, are not subject to income 

tax withholding, except for dividends paid in excess of our taxable accumulated income for the previous fiscal period, which are 
subject to withholding 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 (acciones liberadas) rather than in cash.  

Capital gains tax  

Capital gains recognized by non-resident individuals or entities from the sale, exchange or other disposition of our ADSs or 

Class D shares are not subject to Argentine income tax.  

Personal assets tax  

Argentine individuals and undivided estates, foreign individuals and undivided estates, and foreign entities, are responsible for 
the personal assets tax of 0.5% of the value of any shares or ADSs issued by Argentine entities, held as of December 31 of each year. 
The tax is levied on Argentine issuers of such shares or ADSs, such as us, (which must pay this tax in substitution of the relevant 
shareholders) and is based on the equity value (valor patrimonial proporcional), 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, we are entitled to seek 
reimbursement of such paid tax from the applicable shareholders, including by withholding, foreclosing on the shares, or by 
withholding dividends.  

125 

 
  
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.  

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.  

Transfer taxes  

The sale, exchange or other disposition of our Class D shares or ADSs is not subject to transfer taxes.  

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.  

Other taxes  

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 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. A 3% surcharge calculated on the amount of the court tax would also be imposed by 
the City of Buenos Aires Attorneys Social Security Association.  

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, the Netherlands, Norway, Russia, Spain, Sweden, Switzerland and the 
United Kingdom. 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.  

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 tax purposes and it does not describe all of the tax consequences that may be relevant to holders subject to special rules, 
such as:  
•  

certain financial institutions;  
insurance companies;  
dealers and traders in securities or foreign currencies;  
persons holding Class D shares or ADSs as part of a hedge, “straddle,” wash sale, conversion transaction, integrated 
transaction or similar transaction or persons entering into a constructive sale with respect to the class D shares or ADSs;  
persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;  
entities classified as partnerships for U.S. federal income tax purposes;  
persons liable for the alternative minimum tax;  

•  

•  

•  

•  

•  

•  

126 

 
  
•  

•  

•  

•  

persons who acquired our Class D shares or ADSs pursuant to the exercise of an employee stock option or otherwise as 
compensation;  
persons holding Class D shares or ADSs in connection with a trade or business conducted outside of the United States;  
tax-exempt entities, including “Individual retirement accounts” or “Roth IRAs”; or  
persons holding Class D shares or ADSs that own or are deemed to own ten percent or more of our voting stock.  

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;  
a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States or any 
political subdivision thereof; or  
an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.  

•  

•  

In general, if you own ADSs, you will be treated as the owner of the underlying shares represented by those ADSs for U.S. 

federal income tax purposes. Accordingly, no gain or loss will be recognized if you exchange ADSs for the underlying shares 
represented by those ADSs.  

The U.S. Treasury has expressed concerns that parties to whom American depositary shares are released before shares are 

delivered to the depositary (“pre-release”), or intermediaries in the chain of ownership between U.S. Holders and the issuer of the 
security 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 advisers concerning the U.S. federal, state, local and foreign tax consequences of purchasing, 

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 a 

dividend to the extent paid out of current or accumulated earnings and profits (as determined under U.S. federal income tax 
principles). Because YPF does 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) and the discussion above regarding concerns expressed by the U.S. Treasury, certain dividends 
paid by qualified foreign corporations to certain non-corporate U.S. Holders in taxable years beginning before January 1, 2011 are 
taxable at a maximum rate of 15%. 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. You should consult your own tax advisers to 
determine whether the favorable rate may apply to dividends you receive 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 taxes. The amount of the dividend will be treated as foreign-source dividend income to you and will not be eligible for the 
dividends-received deduction generally allowed to U.S. corporations under the Code.  

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 
should not be required to 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 its receipt.  

127 

 
  
Subject to applicable limitations (including a minimum holding period requirement) that may vary depending upon your 
circumstances and subject to the discussion above regarding concerns expressed by the U.S. Treasury, Argentine income taxes 
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, if any, will not be eligible for credit against the U.S. Holder’s U.S. federal income tax 
liability. U.S. Holders should consult their tax advisers to determine the tax consequences applicable to them as a result of amounts 
paid on account of the Argentine personal assets tax 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 advisers 
regarding the availability of the foreign tax credit under your particular circumstances.  

Sale or other disposition of Class D shares or ADSs  

For U.S. federal income tax purposes, gain or loss you realize on the sale or other disposition of Class D shares or ADSs will 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. The 
amount of your gain or loss will equal the difference between the amount realized on the disposition and your tax basis in the Class D 
shares or ADSs disposed of. Such gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes. The 
deductibility of capital losses is subject to limitations.  

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 2009. 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, certain adverse consequences could apply to you.  

If YPF is treated as a PFIC for any taxable year during which you held a Class D share or ADS, any gain you recognize on a 
sale or other disposition of the Class D share or ADS would be allocated ratably over your holding period for the Class D share or 
ADS. The amounts allocated to the taxable year of the disposition and to any year before YPF became a PFIC would be taxed as 
ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or 
corporations, as appropriate, and an interest charge would be imposed on the amount allocated to such taxable year. Further, any 
distribution in respect of ADSs or ordinary shares in excess of 125 percent of the average of the annual distributions on ADSs or 
ordinary shares received by you during the preceding three years or your holding period, whichever is shorter, would be subject to 
taxation in the manner just described for gains.  

In addition, if YPF were to be treated as a PFIC in a taxable year in which it pays dividends or the prior taxable year, the 15% 

dividend rate discussed above with respect to dividends paid 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.  

Available Information  

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. The SEC maintains a World Wide Web site on the Internet at http://www.sec.gov that 
contains reports and information statements and other information regarding us. Such reports and other information may also be 
inspected at the offices of the New York Stock Exchange, 11 Wall Street, New York, New York 10005, on which YPF’s American 
Depositary Shares are listed.

ITEM 11.   Quantitative and Qualitative Disclosures about Market Risk  

The following quantitative and qualitative information is provided about financial instruments to which we are a party as of 
December 31, 2009, and from which we may incur future gains or 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  

We generally follow a policy of not hedging our debt obligations in U.S. dollars due to the fact that, in 1991, the Argentine 
government instituted a set of economic reforms known as the “Convertibility Plan,” the centerpiece of which was a fixed one-to-one 
rate of exchange between the Argentine peso and the U.S. dollar. Although in view of the Argentine economic crisis the Argentine 
authorities implemented a number of monetary and exchange control measures, including the abolishment of the Convertibility Law, 
we have still not hedged our U.S. dollar debt obligations to date. In addition, our costs and receipts denominated in currencies other 
than the Argentine peso, including the U.S. dollar, often do not match. As a result, we are currently exposed to risks associated with 
changes in foreign currency exchange rates. See “Item 3. Key Information—Risk Factors—Risks Relating to Argentina—We may be 
exposed to fluctuations in foreign exchange rates.”  

The table below provides information about our assets and liabilities denominated in currencies other than pesos (principally 

U.S. dollars) that may be sensitive to changes in foreign exchange rates, as of December 31, 2009.

The objective of our financing strategy is to satisfy capital requirements while minimizing our exposure to interest rate 
fluctuations. To realize such objective, we have borrowed under fixed rate debt instruments, based on the availability of capital and 
prevailing market conditions. We generally follow a policy of not hedging our interest rate exposure.  

The table below provides information about our assets and liabilities as of December 31, 2009 that may be sensitive to changes 

in interest rates.

Crude oil and other hydrocarbon product price exposure  

Our results of operations are also exposed to volatility mainly in the prices of crude oil and oil products, especially in the export 

market. 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 intruments. For 
information on our hydrocarbons delivery commitments as of December 31, 2009, see “Item 4. Information on the Company—
Exploration and Production—Delivery commitments” and Note 10 to the Audited Consolidated Financial Statements.  

ITEM  12.  Description of Securities Other than Equity Securities  
12.1 American Depositary Shares  

Our ADSs are listed on the NYSE under the symbol “YPF”. The Bank of New York Mellon is the depositary issuing ADSs 

pursuant to our deposit agreement (the “Depositary”). Each ADS represents the right to receive one share.  

The Depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering 

ADSs for the purpose of withdrawal or from intermediaries acting for them. The Depositary collects fees for making distributions to 
investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The 
Depositary may collect its annual fee for depositary services by deductions from cash distributions or by directly billing investors or 
by charging the book-entry system accounts of participants acting for them. The Depositary may generally refuse to provide fee-
attracting services until its fees for those services are paid.

The table below sets forth the fees payable, either directly or indirectly, by a holder of ADSs as of the date of this annual report.  

Persons depositing or withdrawing shares must pay: 

U.S.$5.00 (or less) per 100 ADSs (or portion of 100 ADSs) 

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 Repsol 
YPF, an exchange of stock or a distribution of rights) and 
surrender of ADRs 

Cancellation of ADSs for the purpose of withdrawal 

Sale, on behalf of the holder, of rights to subscribe for additional 
shares or any right of any nature distributed by Repsol YPF 

Transfer and registration of shares on Repsol 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 2009, 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, 2009, YPF, under the supervision and with the participation of YPF’s management, including our Chief 

Executive Officer and Chief 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(f) 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 such evaluation, YPF’s Chief Executive Officer and Chief Financial Officer concluded that YPF’s disclosure controls 
and procedures were effective at the reasonable assurance level in ensuring that information relating to YPF, required to be disclosed 
in reports it 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 Chief Executive Officer and Chief 
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 generally accepted accounting principles in Argentina including the reconciliation to U.S. GAAP 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 generally accepted accounting principles, 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 the Chief Executive Officer and Chief 
Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the criteria 
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (“COSO”). Based on this assessment, our management concluded that, as of December 31, 2009, our internal control 
over financial reporting was effective based on those criteria.  

Our internal control over financial reporting as of December 31, 2009 has been audited by Deloitte & Co. S.R.L., an 

independent registered public accounting firm, as stated in their report included in the F-pages.  

Changes in Internal Control Over Financial Reporting  
There has been no change in 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 has materially affected, or is reasonably likely to 
materially affect, internal control over financial reporting.

Report of Independent Registered Public Accounting Firm  

To the Board of Directors and Shareholders of YPF SOCIEDAD ANONIMA:  

We have audited the accompanying consolidated balance sheets of YPF SOCIEDAD ANONIMA (an Argentine Corporation) and its 
controlled and jointly controlled companies (the “Company”) as of December 31, 2009, 2008 and 2007, and the related consolidated 
statements of income, cash flows and changes in shareholders’ equity for each of the three years in the period ended December 31, 
2009. These consolidated financial statements are the responsibility of the Company’s Management. Our responsibility is to express 
an opinion on these consolidated financial statements based on our audits.  

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States of 
America). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial 
statements are free of material misstatements. An audit includes examining, on a test basis, evidence supporting the amounts and 
disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made 
by Management, as well as evaluating the overall financial statements presentation. We believe that our audits provide a reasonable 
basis for our opinion.  

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of 
YPF SOCIEDAD ANONIMA and its controlled and jointly controlled companies as of December 31, 2009, 2008 and 2007, and the 
results of their operations and their cash flows for each of the three years in the period ended December 31, 2009, in conformity with 
generally accepted accounting principles applicable to consolidated financial statements in Argentina.  

Accounting principles generally accepted in Argentina vary in certain significant respects from accounting principles generally 
accepted in the United States of America (“U.S. GAAP”). Information relating to the nature and effect of such differences is presented 
in Notes 13, 14 and 15 to the consolidated financial statements.  

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States of 
America), the Company’s internal control over financial reporting as of December 31, 2009, based on the criteria established in 
Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our 
report dated June 28, 2010 expressed an unqualified opinion on the Company’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm  

To the Board of Directors and Shareholders of YPF SOCIEDAD ANONIMA:  

We have audited the internal control over financial reporting of YPF SOCIEDAD ANONIMA (an Argentine Corporation) and its 
controlled and jointly controlled companies (the “Company”) as of December 31, 2009, based on the criteria established in Internal 
Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s 
management is responsible 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 the Company’s internal control over financial reporting 
based on our audit.  

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States of 
America). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal 
control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal 
control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating 
effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the 
circumstances. We believe that our audit provides a reasonable basis for our opinion.  

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal 
executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, 
management, and other personnel 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper 
management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely 
basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are 
subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with 
the policies or procedures may deteriorate.  

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 
2009, based on the criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission.  

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States of 
America), the consolidated financial statements of YPF SOCIEDAD ANONIMA and its controlled and jointly controlled companies 
as of and for the year ended December 31, 2009 and our report dated June 28, 2010 expressed an unqualified opinion on those 
consolidated financial statements and included an explanatory paragraph stating that the accounting principles generally accepted in 
Argentina vary in certain significant respects from accounting principles generally accepted in the United States of America (“U.S. 
GAAP”) and that the information related to the nature and effect of such differences is presented in Notes 13, 14, and 15 to the 
consolidated financial statements of the Company.

YPF SOCIEDAD ANONIMA AND CONTROLLED AND JOINTLY CONTROLLED COMPANIES  
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  
FOR THE YEARS ENDED DECEMBER 31, 2009, 2008 AND 2007  
(Amounts expressed in millions of Argentine pesos, except where otherwise indicated – Note 1)  

1. SIGNIFICANT ACCOUNTING POLICIES  
The financial statements of YPF Sociedad Anónima (“YPF”) and its controlled and jointly controlled companies (the “Company”) 
have been prepared in accordance with generally accepted accounting principles applicable to consolidated financial statements in 
Argentina (“Argentine GAAP”), and taking into consideration the regulations of the National Securities Commission (“CNV”).  

In accordance with generally accepted accounting principles and current Argentine legislation, the presentation of individual financial 
statements is mandatory. Consolidated financial statements are to be included as supplementary information to the individual financial 
statements. For the purpose of this filing, individual financial statements have been omitted since they are not required for the United 
States Securities and Exchange Commission (“SEC”) reporting purposes.  

Furthermore, certain disclosures related to formal legal requirements for reporting in Argentina have been omitted for purposes of 
these consolidated financial statements, since they are not required for SEC reporting purposes.  

On March 20, 2009, the Argentine Federation of Professional Councils in Economic Sciences (“FACPCE”) approved the Technical 
Resolution No. 26 “Adoption of the International Financial Reporting Standards (“IFRS”) of the International Accounting Standards 
Board (“IASB”)”. Such resolution was approved by the CNV through General Resolution No. 562/09 dated December 29, 2009, for 
certain publicly-traded entities under Law No. 17,811. The application of such rules will be mandatory for YPF for the fiscal year 
beginning on January 1, 2012.  

Presentation of financial statements in constant Argentine pesos  
The financial statements reflect the effect of changes in the purchasing power of money by the application of the method for 
restatement in constant Argentine pesos set forth in Technical Resolution No. 6 of the FACPCE and taking into consideration General 
Resolution No. 441 of the CNV, which established the discontinuation of the restatement of financial statements in constant Argentine 
pesos as from March 1, 2003.  

Basis of consolidation  
Following the methodology established by Technical Resolution No. 21 of the FACPCE, YPF has consolidated its balance sheets and 
the related statements of income and cash flows as follows:  

• 

• 

Investments and income (loss) related to controlled companies in which YPF has the number of votes necessary to control 
corporate decisions are substituted for such companies’ assets, liabilities, net revenues, cost and expenses, which are 
aggregated to YPF’s balances after the elimination of intercompany profits, transactions, balances and other consolidation 
adjustments and minority interest if applicable.  
Investments and income (loss) related to companies in which YPF holds joint control are consolidated line by line on the 
basis of YPF’s proportionate share in their assets, liabilities, net revenues, cost and expenses, considering the elimination 
of intercompany profits, transactions, balances and other consolidations adjustments. The effect of this proportional 
consolidation for the year ended December 31, 2009 and comparative information, is disclosed in Note 13.b.  

Foreign subsidiaries are defined as integrated companies when they carry out their operations as an extension of the parent company’s 
operations or as non-integrated companies when they collect cash and other monetary items, incur expenses, generate income and are 
financed principally through their own resources. Assets and liabilities of non-integrated foreign subsidiaries are translated into 
Argentine pesos at the exchange rate prevailing as of the end of each year. Income statements are translated using the relevant 
exchange rate at the date of each transaction. Exchange differences arising from the translation process are included as a component of 
shareholder’s equity in the account “Deferred Earnings”, which are maintained until the sale or complete or partial reimbursement of 
capital of the related investment occurs. Assets, liabilities and income statements of integrated foreign subsidiaries are translated at the 
relevant exchange rate at the date of each transaction. Exchange differences arising from the translation process are credited (charged) 
to the income statement in the account “Gains (losses) on assets—Exchange differences”.  

The consolidated financial statements are based upon the latest available financial statements of those companies in which YPF holds 
control or joint control, taking into consideration, if applicable, significant subsequent events and transactions, available management 
information and transactions between YPF and the related company, which could have produced changes on the latter’s shareholders’ 
equity.  

F - 9 

 
The valuation methods employed by the controlled and jointly controlled companies are consistent with those followed by YPF. If 
necessary, adjustments to the accounting information have been made to conform the accounting principles used by these companies 
to those of YPF. Main adjustments are related to the application of the general accepted accounting principles in Argentina to foreign 
subsidiaries’ financial statements.  

Cash and equivalents  
In the statements of cash flows, the Company considers cash and all highly liquid investments with an original maturity of less than 
three months to be cash and equivalents.  

Revenue recognition 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.  

Subsidies and incentives are recognized as sales in the income statement in the year in which the conditions for obtaining them are 
accomplished.  

Revenues and costs related to construction activities, performed by a domestic subsidiary of YPF, are accounted by the percentage of 
completion method. When adjustments in contract values or estimated costs are determined, any change from prior estimates is 
reflected in earnings in the current year. Anticipated losses on contracts in progress are expensed as soon as they become evident.  

Joint ventures and other agreements  
The Company’s interests in oil and gas related joint ventures and other agreements involved in oil and gas exploration and production, 
have been consolidated line by line on the basis of the Company’s proportional share in their assets, liabilities, revenues, costs and 
expenses (Note 6).  

Production concession and exploration permits  
According to Argentine Law No. 24,145 issued in November 1992, YPF’s areas were converted into production concession and 
exploration permits under Law No. 17,319, which has been amended by Law No. 26,197. Pursuant to these laws, the hydrocarbon 
reservoirs located in Argentine onshore territories and offshore continental shelf, belong to the Provinces or the Nation, depending on 
the location. Exploration permits may have a term of up to 17 years and production concessions have a term of 25 years, which may 
be extended for an additional ten–year term (Note 10.c).  

Fair value of financial instruments and concentration of credit risk  
The carrying value of cash, current investments, trade receivables and current liabilities approximates its fair value due to the short 
maturity of these instruments. Furthermore, the fair value of loans receivable, which has been estimated based on current interest rates 
offered to the Company at the end of each year, for investments with the same remaining maturity, approximates its carrying value. As 
of December 31, 2009, 2008 and 2007 the fair value of loans payable estimated based on market prices or current interest rates at the 
end of each year amounted to 6,827, 4,399 and 1,049, respectively.  

Financial instruments that potentially expose the Company to concentration of credit risk consist primarily of cash, current 
investments, trade receivables and other receivables. The Company invests cash excess primarily in high liquid investments in 
financial institutions both in Argentina and abroad with strong credit rating. In the normal course of business, the Company provides 
credit based on ongoing credit evaluations to its customers and certain related parties. Additionally, the Company accounts for credit 
losses based on specific information of its clients. Credit risk on trade receivables is not significant, as a result of the Company’s large 
customer base.  

As of December 31, 2009, YPF does not hold derivative financial instruments.  

Use of estimates  
The preparation of financial statements in conformity with generally accepted accounting principles requires Management to make 
estimates and assumptions that affect reported assets, liabilities, revenues and expenses and disclosure of contingencies. Future results 
could differ from the estimates made by Management.  

Earnings per share  
Earnings per share have been calculated based on the 393,312,793 shares outstanding during the years ended as of December 31, 
2009, 2008 and 2007.  

F - 10 

 
2. VALUATION CRITERIA  
The principal valuation criteria used in the preparation of the financial statements are as follows:  

a)  Cash, current investments, trade and other receivables and payables:  

•  

•  

Amounts in Argentine pesos have been stated at face value, which includes accrued interest through the end of each year, 
if applicable. Investments with price quotation have been valued at fair value as of the end of each year.  
Amounts in foreign currencies have been valued at the relevant exchange rates as of the end of each year, including 
accrued interest, if applicable. Investments with price quotation have been valued at fair value at the relevant exchange 
rate in effect as of the end of each year. Exchange differences have been credited (charged) to current income. Additional 
information on assets and liabilities denominated in foreign currency is disclosed in Note 16.e.  

When generally accepted accounting principles require the valuation of receivables or payables at their discounted value, that 
value does not differ significantly from their face value.  
If applicable, allowances have been made to reduce receivables to their estimated realizable value.  

b) 

Inventories:  
•  

Refined products, products in process, crude oil and natural gas have been valued at current production cost or 
replacement cost, as applicable, as of the end of each year.  
Raw materials and packaging materials have been valued at cost, which does not differ significantly from its replacement 
cost as of the end of each year.  

•  

Valuation of inventories does not exceed their estimated realizable value.  

c)  Noncurrent investments:  

These include the Company’s investments in companies under significant influence and holdings in other companies. These 
investments are detailed in Note 16.b and have been valued using the equity method, except for holdings in other companies, 
which have been valued at cost remeasured as detailed in Note 1.  

Investments in Gasoducto del Pacífico (Argentina) S.A., Gasoducto del Pacífico (Cayman) Ltd. and Oleoducto Trasandino 
(Chile) S.A., where less than 20% direct or indirect interest is held, are accounted by the equity method since the Company 
exercises significant influence over these companies in making operation and financial decisions based on its representation on 
the Boards of Directors and/or the significant transactions between YPF and such companies.  
If applicable, allowances have been made to reduce investments to their estimated recoverable value. The main factors for the 
recognized impairment were the devaluation of the Argentine peso, lower activity expectations, events of default on certain 
debts and the de-dollarization and freezing of certain utility rates.  
Holdings in preferred shares have been valued at equity method considering the provisions defined in the respective bylaws.  
If necessary, adjustments have been made to the accounting information to conform the accounting principles used by 
companies under significant influence to those of the Company.  
The investments in companies under significant influence, 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 Company and the related companies which have 
produced changes on the latter shareholders’ equity.  
As from the effective date of Law No. 25,063, dividends, either in cash or in kind, that the Company receives from investments 
in other companies and which are in excess of the accumulated taxable income that these companies carry upon distribution 
shall be subject to a 35% income tax withholding as a sole and final payment. The Company 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.  

d) 

Fixed assets:  
Fixed assets have been valued at acquisition cost remeasured as detailed in Note 1, less related accumulated depreciation. 
Depreciation rates, representative of the useful life assigned, applicable to each class of asset, are disclosed in Note 16.a. For 
those assets whose construction requires an extended period of time, financial costs corresponding to third parties’ financing 
have been capitalized during the assets’ construction period.  

F - 11 

 
  
Oil and gas producing activities  
The Company follows the “successful effort” method of accounting for its oil and gas exploration and production operations. 
Accordingly, exploratory costs, excluding the costs of exploratory wells, have been charged to expense as incurred. Costs of 
drilling exploratory wells, including stratigraphic test wells, have been capitalized pending determination as to whether the wells 
have found proved reserves that justify commercial development. If such reserves were 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 when drilling is completed. In those cases, the cost of drilling the exploratory well 
shall continue to be capitalized if the well has found a sufficient quantity of reserves to justify its completion as a producing well 
and the enterprise is making sufficient progress assessing the reserves and the economic and operating viability of the project. If 
any of the mentioned conditions are not met, cost of drilling exploratory wells is charged to expense. As of the issuance date of 
these financial statements, there are no exploratory wells for more than one year after the completion of the drilling.  
•  

Intangible 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 related to producing activities have been depreciated by field on the unit-of-production basis by 
applying the ratio of produced oil and gas to estimate recoverable proved and developed oil and gas reserves.  

The capitalized costs related to acquisitions of properties and extension of concessions with proved reserves have been 
depreciated by field on the unit-of-production basis by applying the ratio of produced oil and gas to proved oil and gas 
reserves.  
The capitalized costs related to areas with unproved reserves are periodically reviewed by Management to ensure that the 
carrying value does not exceed their estimated recoverable value.  
Revisions of crude oil and natural 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 
independent petroleum engineers on a three-year rotation plan.  
Costs related to hydrocarbon wells 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 likewise the complexity with respect to different geographic areas where the wells are located, the current 
costs incurred in plugging are used for estimating the plugging 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.  

•  

•  

•  

•  

•  

Other fixed assets  
•  

The Company’s other fixed assets are depreciated using the straight-line method, with depreciation rates based on the 
estimated useful life of each class of property.  

Fixed assets’ maintenance and repairs have been charged to expense as incurred.  
Major inspections, necessary to continue to operate the related assets, are capitalized and depreciated using the straight-line 
method over the period of operation to the next major inspection.  
Renewals and betterments that extend the useful life and/or increase the productive capacity of properties are capitalized. As 
fixed assets are retired, the related cost and accumulated depreciation are eliminated from the balance sheet.  
The Company capitalizes the costs incurred in limiting, neutralizing or preventing environmental pollution only in those cases in 
which at least one of the following conditions is met: (a) the expenditure improves the safety or efficiency of an operating plant 
(or other productive asset); (b) the expenditure prevents or limits environmental pollution at operating facilities; or (c) the 
expenditures are incurred to prepare assets for sale and do not raise the assets’ carrying value above their estimated recoverable 
value.  
The carrying value of the fixed asset of each business segment, as defined in Note 8, does not exceed their estimated recoverable 
value.  

e) 

Salaries and Social Security – Pension Plans and other Postretirement and Postemployment benefits:  
As of December 31, 2007, YPF Holdings Inc., which has operations in the United States of America, had three trustee defined- 
benefit pension plans and other postretirement and postemployment benefits.  
In March 2008, YPF Holdings Inc. acquired certain contracts from Prudential Insurance Company (“Prudential”) to settle the 
liability associated with two of those defined-benefit pension plans, paying a premium amount of US$ 115 million. Prudential 
assumed the liabilities under these pension plans as of March 20, 2008.  

F - 12 

 
  
f) 

The funding policy related to the outstanding pension plan as of December 31, 2009, is to contribute amounts to the plan 
sufficient to meet the minimum funding requirements under governmental regulations, plus such additional amounts as 
Management may determine to be appropriate.  
In addition, YPF Holdings Inc. provides certain health care and life insurance benefits for eligible retired employees, and also 
certain insurance, and other postemployment benefits for eligible individuals in case employment is terminated by YPF 
Holdings Inc. before their normal retirement. YPF Holdings Inc. accrues the estimated cost of retiree benefit payments during 
employees’ active service periods. Employees become eligible for these benefits if they meet minimum age and years of service 
requirements. YPF Holdings Inc. accounts for benefits provided when the minimum service period is met, payment of the 
benefit is probable and the amount of the benefit can be reasonably estimated.  
During the year 2008, YPF Holdings Inc. curtailed the postretirement health care benefits to certain retirees. The effect of the 
curtailment on net income has not been material (Note 3.h).  
The defined benefits and postretirement pension plans mentioned above are valued at net present value, are accrued on the years 
of active service of employees and are disclosed as non-current liabilities in the “Salaries and social security” account. As of 
December 31, 2009, the actuarial losses and gains were charged to the “Other income (expense), net” account of the statement 
of income. As of December 31, 2008 and 2007, the unrecognized actuarial losses and gains generated since December 31, 2003 
were disclosed net of the present value of the obligation and were recognized in the statement of income during the expected 
average remaining service period of the employees participating in the plans and the life expectancy of the retired employees. 
The effect on net income related to the recognition of the change in the accounting criteria for actuarial gains and losses for the 
years ended December 31, 2008 and 2007, is not material. YPF Holdings Inc. updates the actuarial assumptions at the end of 
each year.  
Other postretirement and postemployment benefits are funded as claims are incurred.  
The additional disclosures related to the pension plans and other postretirement and postemployment benefits, are included in 
Note 3.h.  

Taxes, withholdings and royalties:  
Income tax and tax on minimum presumed income  
The Company recognizes the income tax applying the liability method, which considers the effect of the temporary differences 
between the financial and tax basis of assets and liabilities and the tax loss carryforwards and other tax credits, which may be 
used to offset future taxable income, at the current statutory rate of 35%.  
In deferred income tax computations, the difference between the book value of fixed assets remeasured into constant Argentine 
pesos and their corresponding historical cost used for tax purposes is a temporary difference to be considered in deferred income 
tax computations. However, generally accepted accounting principles in Argentina provide the option to disclose the mentioned 
effect in a note to the financial statements instead. The Company adopted this latter criterion (Note 3.j).  
Additionally, the Company calculates tax on minimum presumed income applying the current 1% tax rate to taxable assets as of 
the end of each year. This tax complements income tax. The Company’s tax liability will coincide with the higher between the 
determination of tax on minimum presumed income and the Company’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.  
For the years ended December 31, 2009, 2008 and 2007, the amounts determined as current income tax were higher than tax on 
minimum presumed income and they were included in the “Income tax” account of the statement of income of each year.  

Royalties and withholding systems for hydrocarbon exports  
A 12% royalty is payable on the estimated value at the wellhead of crude oil production and the commercialized natural gas 
volumes (see additionally Note 10.c). The estimated value is calculated based upon the approximate sale price of the crude oil 
and gas produced, less the costs of transportation and storage. To calculate the royalties, the Company has considered price 
agreements according to crude oil buying and selling operations obtained in the market for certain qualities of such product, and 
has applied these prices, net of the discounts mentioned above, according to regulations of Law No. 17,319 and its amendments.  
Royalty expense is accounted for as a production cost.  
Law No. 25,561 on Public Emergency and Exchange System Reform, 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 also established specifically that this regime is also applicable to exports from “Tierra del 
Fuego” province, which were previously exempted. Up to March 2008, Resolution No. 534/2006 of the Ministry of Economy 
and Production (“MEP”) was in force, which, as from July 25, 2006, had raised the natural gas withholding rate from 20% to 

F - 13 

 
  
  
45% and had established the natural gas import price from Bolivia as the basis for its determination. Resolution No. 532/2004 
(in force until November, 2007) had settled the withholding rate for crude oil between 25% and 45% in function of the West 
Texas Intermediate (“WTI”) price, and between 5% and 25% for other refined products. On November 16, 2007, the MEP 
published Resolution No. 394/2007, modifying the withholding regime on exports of crude oil and other refined products. The 
new regime provides reference prices and floor prices which in conjunction with the WTI determine the export rate for each 
product. For crude oil, when the WTI exceeds the reference price of US$ 60.9 per barrel, the producer is allowed to collect a 
floor price of US$ 42 per barrel, depending on the quality of the crude oil sold, with the remainder being withheld by the 
Argentine Government. When the WTI is under the reference price but over US$ 45 per barrel, a 45% withholding rate should 
be applied. If such price is under US$ 45 per barrel, the Government will have to determine the export rate within a term of 90 
business days. 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. As of 
December 31, 2009, the crude oil withholding rate determined according to Resolutions No. 394/2007 and No. 127/2008 of 
MEP, also currently applies to diesel, gasoline products and other refined products. In addition, the procedure above mentioned 
also applies to fuel oil, petrochemical gasoline, lubricants and liquefied petroleum gas (including propane, butane and blends) 
and other refined products, considering different reference and floor prices disclosed in the mentioned resolutions.  
Natural gas export clients are currently absorbing the payment of export duties established by the Resolution No. 127/08. Some 
of them have paid reserving their rights to future claims.  
Hydrocarbon export withholdings are charged to the “Net sales” account of the statement of income.  

g)  Allowances and reserves:  

•  

•  

Allowances: amounts have been provided in order to reduce the valuation of trade receivables, other receivables, 
noncurrent investments and fixed assets based on the analysis of doubtful accounts and on the estimated recoverable value 
of these assets.  
Reserves for losses: amounts have been provided for various contingencies which are probable and can be reasonably 
estimated, based on Management’s expectations and in consultation with legal counsels. Reserves for losses are required 
to be accounted at the discounted value as of the end of each year, however, as their face value does not differ 
significantly from discounted values, they are recorded at face value.  

The activity in the allowances and reserves accounts is set forth in Note 16.c.  

h)  Environmental liabilities:  

i) 

j) 

Environmental liabilities are recorded when environmental assessments and/or remediation are probable and can be reasonably 
estimated. Such estimates are based on either detailed feasibility studies of remediation approach and cost for individual sites or 
on the Company’s estimate of costs to be incurred based on historical experience and available information based on the stage of 
assessment and/or remediation of each site. As additional information becomes available regarding each site or as environmental 
standards change, the Company revises its estimate of costs to be incurred in environmental assessment and/or remediation 
matters.  

Shareholder’s equity accounts:  
These accounts have been remeasured in Argentine pesos as detailed in Note 1, except for “Subscribed Capital” account, which 
is stated at its historical value. The adjustment required to state this account in constant Argentine pesos is disclosed in the 
“Adjustment to Contributions” account.  
The account “Deferred Earnings” includes the exchange differences generated by the translation into pesos of the investments in 
non-integrated foreign companies.  

Statement of income accounts:  
The amounts included in the income statement accounts have been recorded by applying the following criteria:  
•  

Accounts which accumulate monetary transactions at their face value.  
Cost of sales has been calculated by computing units sold in each month at the replacement cost of that month.  
Depreciation of non-monetary assets, valued at acquisition cost, has been recorded based on the remeasured cost of such 
assets as detailed in Note 1.  
Holding gains (losses) on inventories valued at replacement cost have been included in the “Holding (losses) gains on 
inventories” account.  
Income (loss) on long-term investments in which significant influence is held, has been calculated on the basis of the 
income (loss) of those companies and was included in the “Income on long-term investments” account.

The “Reversal of impairment of other current assets” account for the year ended December 31, 2007, includes the reversal 
of the impairment recorded as a consequence of the decision of the Company to suspend the selling process of certain oil 
and gas exploration and production assets on April, 2007. Consequently, the book value of the mentioned assets was 
transferred to fixed assets held for use.

(2)  Accrues interest at a variable interest rate of BADLAR plus 1.75%.  

In connection with the issued Negotiable Obligations, YPF has agreed for itself and its controlled companies to certain covenants, 
including among others, to pay all liabilities at their maturity and not to create other encumbrances that exceed 15% of total 
consolidated assets. If the Company does not comply with any covenant, the trustee or the holders representing a percentage that 
varies between 10% and 25% of the total principal amount of the outstanding Negotiable Obligations may declare the principal and 
accrued interest immediately due and payable.  

Financial debt contains customary covenants for contracts of this nature, including negative pledge, material adverse change and 
cross–default clauses. Almost of all YPF’s total outstanding debt is subject to cross–default provisions.  

The Shareholders’ meeting held on January 8, 2008, approved a Notes Program for an amount up to US$ 1,000 million. Proceeds from 
this offering shall be used exclusively to invest in fixed assets and working capital in Argentina. On September 24, 2009, YPF issued 
under the mentioned program the Negotiable Obligations “Class I” at variable interest, with final maturity in 2011, for an amount of 
205 million of Argentine pesos. Additionally, on March 4, 2010, the Company issued under the mentioned program the Negotiable 
Obligations “Class II” at variable interest, with final maturity in 2011, for an amount of 143 million of Argentine pesos and the 
Negotiable Obligations “Class III” at fixed interest, with final maturity in 2013, for an amount of US$ 70 million. All the mentioned 
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.

Export sales, net of withholdings taxes, for the years ended December 31, 2009, 2008 and 2007 were 4,904, 7,228 and 8,400, 
respectively. Export sales were mainly to the United States of America and Brazil.  

9. SOCIAL AND OTHER EMPLOYEE BENEFITS  
a) 

Performance Bonus Programs:  
These programs cover certain YPF and its controlled companies’ personnel. These bonuses are based on compliance with 
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 will be paid in cash.  
The amount charged to expense related to the mentioned Performance Bonus Programs was 89, 72 and 61 for the years ended 
December 31, 2009, 2008, and 2007, respectively.  

b)  Retirement Plan:  

Effective March 1, 1995, YPF 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 2% and 9% of his monthly compensation and YPF will 
pay an amount equal to that contributed by each member.  
The plan members will receive the YPF’s 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. YPF has the right to 
discontinue this plan at any time, without incurring termination costs.  
The total charges recognized under the Retirement Plan amounted approximately 15, 13 and 11, for the years ended 
December 31, 2009, 2008 and 2007, respectively.

10. COMMITMENTS AND CONTINGENCIES  
Pending lawsuits and contingencies:  
a) 
As of December 31, 2009, the Company has reserved 2,300 in connection with the pending lawsuits, claims and contingencies 
which are probable and can be reasonably estimated. The most significant pending lawsuits and contingencies reserved are 
described in the following paragraphs.  

•  

•  

Pending lawsuits: In the normal course of its business, the Company has been sued in numerous labor, civil and 
commercial actions and lawsuits. Management, in consultation with the external counsels, has reserved an 
allowance considering its best estimation, based on the information available as of the date of the issuance of these 
financial statements, including counsel fees and judicial expenses.  
Liquefied petroleum gas market: On March 22, 1999, YPF was notified of Resolution No. 189/1999 from the 
former Secretariat of Industry, Commerce and Mining of Argentina, which imposed a fine on the Company of 109 
based on the interpretation that YPF had purportedly abused of its dominant position in the bulk liquefied 
petroleum gas (“LPG”) market due to the existence of different prices between the exports of LPG and the sales to 
the domestic market from 1993 through 1997. In July 2002, the Argentine Supreme Court confirmed the fine and 
YPF carried out the claimed payment.  
Additionally, Resolution No. 189/1999 provided the beginning of an investigation in order to prove whether the 
penalized behavior continued from October 1997 to March 1999. On December 19, 2003, the National Antitrust 
Protection Board (the “Antitrust Board”) imputed the behavior of abuse of dominant position during the 
previously mentioned period to the Company. On January 20, 2004, the Company answered the notification: 
(i) opposing the preliminary defense claiming the application of the statutes of limitation and alleging the 
existence of defects in the imputation procedure (absence of majority in the resolution that decided the imputation 
and pre-judgment by its signers); (ii) arguing the absence of abuse of dominant position; and (iii) offering the 
corresponding evidence.  
The request of invalidity by defects in the imputation procedure mentioned above was rejected by the Antitrust 
Board. This resolution of the Antitrust Board was confirmed by the Economic Penal Appellate Court, and it was 
confirmed, on September 27, 2005, pursuant to the Argentine Supreme Court’s (“CSJN”) rejection of the 
complaint made by YPF due to the extraordinary appeal denial.  
Additionally, on August 31, 2004, YPF filed an appeal with the Antitrust Board in relation to the resolution that 
denied the claim of statutes of limitation. The Antitrust Board conceded the appeal and remitted proceedings for its 
resolution by the Appeal Court. However, in March 2006, YPF was notified that the proceedings were opened for 
the production of evidence. During August and September 2007, testimonial hearings were held for YPF’s 
witnesses. On August 12, 2008, the Appeal Court in Criminal Economic Matters rejected the statute of limitation 
argument opposed by YPF. Such decision was appealed by the Company. Upon the confirmation of the Antitrust 
Board’s decision given by the Chamber B, YPF has appealed that judgment by cassation and extraordinary 
appeals, because the Antitrust Board applied Law No. 22,262 and Chamber B applied Law No. 25,156. The latter 
mentioned rejected both appeals (cassation and extraordinary), consequently YPF presented complaint appeals 
against the cassation appeal, denied on December 18, 2008, and against the Extraordinary Appeal, denied on 
February 17, 2009. Regarding the administrative proceedings before the Antitrust Board, the evidence production 
period has ended, and on November 25, 2009, YPF presented its closing statement. On December 22, 2009, 
Chamber IV of the Court of Cassation rejected the appeal against the rejection of YPF’s statute of limitations 
argument by Chamber B of the National Court of Appeals in Criminal Economic Matters. The extraordinary 
appeal, filed with the cassation appeal, is still pending before the CSJN. Furthermore, on December 21, 2009, YPF 
filed another claim concerning the statutes of limitations before the Antitrust Board. On April 19, 2010, the 
Antitrust Board rejected the presentation and YPF appealed the decision.  
Despite the solid arguments expressed by YPF, the mentioned circumstances make evident that, preliminarily, the 
Antitrust Board denies the defenses filed by the Company and that it is reluctant to modify the doctrine provided 
by the Resolution No. 189/1999 and, furthermore, the Appeal Court in Criminal Economic Matters decisions tend 
to confirm the decisions made by the Antitrust Board.  

•  

Liabilities and contingencies assumed by the Argentine Government: The YPF Privatization Law provided for the 
assumption by the Argentine Government of certain liabilities of the predecessor 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 
advance the payment 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.

•  

Natural gas market:  
Pursuant to Resolution No. 265/2004 of the Secretariat of Energy, the Argentine Government created a program of 
“useful” curtailment of natural gas exports and their associated transportation service. 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 of the 
Secretariat of Energy 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 Injections mechanism created by this Resolution. By 
means of 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 of the Argentine market (“Additional Injection Requirements”). Such additional volumes are 
not contractually committed by YPF, who 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 
the Secretariat of Energy Resolution No. 599/2007, modifying the conditions for the imposition of the 
requirements, depending on whether the producers have signed or not the proposed agreement, ratified by such 
resolution, between the Secretariat of Energy and the Producers. Additionally, the Argentine Government, through 
instructions made using different procedures, has ordered limitations over natural gas exports (in conjunction with 
the Program and the Permanent Additional Injection, named the “Restrictions”).  
As a result of the Restrictions, in several occasions since 2004, YPF has been 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.  
The Company has challenged the Program, the Permanent Additional Injection and the Additional Injection 
Requirements as arbitrary and illegitimate, and has invoked vis-à-vis the relevant clients that such measures of the 
Argentine Government constitute a fortuitous case or force majeure event (act of authority) that releases the 
Company from any liability and/or penalty for the failure to deliver the contractual volumes. These clients have 
rejected the force majeure argument invoked by the Company, demanding the payment of indemnifications and/or 
penalties for the failure to comply with firm supply commitments, and/or reserving their rights to future claims in 
such respect (the “Claims”).  
Electroandina S.A. and Empresa Eléctrica del Norte Grande S.A. (“Edelnor”) have rejected the force majeure 
argument invoked by the Company and have invoiced the penalty stipulated under the “deliver or pay” clause of 
the contract for cutbacks accumulated as of September, 2007, for a total amount of US$ 93 million. These invoices 
have been rejected by the Company, assuming no responsibility. Furthermore, the above-mentioned companies 
had notified the formal start-up period of negotiations previous to any arbitration complaint. Although such period 
is overdue, the Company has not been notified of the initiation of the arbitration proceedings.  
Additionally, on June 25, 2008, AES Uruguaiana Emprendimientos S.A. (“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 through 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 the interruption of the fulfillment of its 
commitments alleging delay and breach of YPF obligations. The Company has rejected this notification. On 
December 4, 2008, YPF notified that having ceased the force majeure conditions, pursuant to the contract in force, 
it would suspend its delivery commitments, due to the 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 and on 
March 20, 2009, notified YPF the termination of the contract. Subsequently, AESU initiated an arbitration process 
in which it claims, among other matters that the Company considers inappropriate, the payment of the “deliver or 
pay” penalties mentioned above. YPF has also started an arbitration process against AESU claiming, among other 
matters, the declaration that the termination of the contract by AESU was unilateral and illegal under its 
responsibility. Both arbitral complaints had been answered by the parties by requesting their rejection.  
Furthermore, there are certain claims in relation with payments of natural gas transportation contracts associated 
with exports of such hydrocarbon. Consequently, one of the parties commenced mediation proceedings in order to 
determine the merits of such claims. The mediation proceedings did not result in an agreement and YPF was 
notified of the lawsuit filed against it in which the plaintiff is claiming the fulfilment of contractual obligations and 
the payment of unpaid invoices while reserving the right to claim for damages. YPF has answered the mentioned 
claims. In the opinion of YPF’s management the claims received up to date will not have a material adverse effect 
on future results of operations.  

F - 27 

 
  
In addition, there are other claims in connection with the natural gas market in which YPF is party, which are not 
individually significant.  
As of December 31, 2009, the Company has reserved costs for penalties associated with the failure to deliver the 
contractual volumes of natural gas in the export and domestic markets which are probable and can be reasonably 
estimated.  

•   La Plata and Quilmes environmental claims:  

La Plata: In relation with the operation of the refinery that the Company 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, the Company 
submitted a presentation before the Environmental Ministry 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 of 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.  
Quilmes: Citizens which 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 of 47 plus interests as a 
compensation for supposedly personal damages. They base their claim mainly on a fuel leak in the poliduct 
running from La Plata to Dock Sud, currently operated by YPF, which occurred in 1988 as a result of an illicit 
detected at that time, being at that moment YPF a state-owned company. Fuel would have emerged and became 
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. YPF has also 
notified the Argentine Government that it will receive a citation, due to its obligation to indemnify the Company 
against any liability according to Law No. 24,145, prior to requesting its citation before the Court upon YPF’s 
response to the complaint. 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 award is still pending. On November 25, 2009, the proceedings were transferred to the Federal Court on Civil 
and Commercial Matters Nº 3, Secretariat Nº 6 in Buenos Aires City and on March 4, 2010, YPF answered the 
complaint. In addition, other 33 judicial claims related to similar matters have been brought against YPF 
amounting to approximately 17. Additionally, the Company is aware of the existence of other out of court claims 
which are based on similar allegations.  

•   Environmental contingencies and other claims of YPF Holdings Inc.- a wholly owned subsidiary of YPF.  

Laws and regulations relating to health and environmental quality in the United States of America affect nearly all 
the operations of YPF Holdings Inc. 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.  
YPF Holdings Inc. believes that its policies and procedures in the area of pollution control, product safety and 
occupational health are adequate to prevent unreasonable risk of environmental and other damage, and of resulting 
financial liability, in connection with its business. Some risk of environmental and other damage is, however, 
inherent in particular operations of YPF Holdings Inc. and, as discussed below, Maxus Energy Corporation 
(“Maxus”) and Tierra Solutions Inc. (“Tierra”), both controlled by YPF Holdings Inc., could have certain potential 
liabilities associated with operations of Maxus’ former chemical subsidiary.  
YPF Holdings Inc. cannot predict what environmental legislation or regulations will be enacted in the future or 
how existing or future laws or regulations will be administered or enforced. Compliance with more stringent law 
regulations, as well as more vigorous enforcement policies of the regulatory agencies, could in the future require 
material expenditures by YPF Holdings Inc. for the installation and operation of systems and equipment for 
remedial measures, possible dredging requirements, among other things. Also, certain laws allow for recovery of 
natural resource damages from responsible parties and ordering the implementation of interim remedies to abate an 
imminent and substantial endangerment to the environment. Potential expenditures for any such actions cannot be 
reasonably estimated.  
In the following discussion, references to YPF Holdings Inc. include, as appropriate and solely for the purpose of 
this information, references to Maxus and Tierra.  
In connection with the sale of Maxus’ former chemical subsidiary, 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 the selling date, 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.  

F - 28 

 
  
As of December 31, 2009, reserves for the environmental contingencies and other claims totaled approximately 
531. YPF Holdings Inc.’s Management believes it has adequately reserved for all environmental contingencies, 
which are probable and can be reasonably estimated; however, changes in circumstances, including new 
information or new requirements of governmental entities, could result in changes, including additions, to such 
reserves in the future. The most significant contingencies are described in the following paragraphs:  
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. 
The approved remedy has been completed and paid for by Tierra. This project is in the operation and maintenance 
phase. YPF Holdings Inc. has reserved approximately 53 as of December 31, 2009, in connection with such 
activities.  
Passaic River, New Jersey. Studies have indicated that sediments of the Newark Bay watershed, including the 
Passaic River adjacent to the former Newark plant, are contaminated with hazardous chemicals from many 
sources. These studies suggest that older and more contaminated sediments located adjacent to the former Newark 
plant generally are buried under more recent sediments deposits. Maxus, forced to act on behalf of Occidental, 
negotiated an agreement with the EPA under which Tierra has conducted further testing and studies near the plant 
site. While some work remains in a pending state, these studies were substantially completed in 2005.  

In addition:  

•  

•  

•   YPF Holdings Inc. has been conducting similar studies under their own auspices for several years.  
•   The EPA and other agencies are addressing the lower Passaic River in a joint federal, state, local and private 
sector cooperative effort designated as the Lower Passaic River Restoration Project (“PRRP”). Tierra, along 
with other entities, participated in an initial remedial investigation and feasibility study (“RIFS”) in 
connection with the PRRP. The parties are discussing the possibility of further work with the EPA. The 
entities have agreed the allocations of costs associated with the RIFS, based on a number of considerations.  
In 2003, the DEP issued Directive No. 1 to Occidental and Maxus and certain of their respective related 
entities as well as other third parties. Directive No. 1 seeks to address natural resource damages allegedly 
resulting from almost 200 years of historic industrial and commercial development along a portion of the 
Passaic River and a part of its watershed. Directive No. 1 asserts that the named entities are jointly and 
severally liable for the alleged natural resource damages without regard to fault. The DEP has asserted 
jurisdiction in this matter even though all or part of the lower Passaic River is subject to the PRRP. Directive 
No. 1 calls for the following actions: interim compensatory restoration, injury identification, injury 
quantification and value determination. Maxus and Tierra responded to Directive No. 1 setting forth good 
faith defenses. Settlement discussions between the DEP and the named entities have been hold, however, no 
agreement has been reached or is assured.  
In 2004, the EPA and Occidental entered into an administrative order on consent (the “AOC”) pursuant to 
which Tierra (on behalf of Occidental) has agreed to conduct testing and studies to characterize 
contaminated sediment and biota in the Newark bay. The initial field work on this study, which includes 
testing in the Newark Bay, has been substantially completed. Discussions with the EPA regarding additional 
work that might be required are underway. EPA has notified other companies in relation to the 
contamination of the Newark Bay. Additionally, Tierra, acting on behalf of Occidental, is performing a 
separate RIFS to characterize sediment contamination and evaluate remediation, if necessary, in certain 
portions of the Hackensack River, the Arthur Kill River and the Kill van Kull River.  
In December 2005, the DEP issued a directive to Tierra, Maxus and Occidental directing said parties to pay 
the State of New Jersey’s cost of developing a Source Control Dredge Plan focused on allegedly dioxin – 
contaminated sediment in the lower six–mile portion of the Passaic River. The development of this plan is 
estimated by the DEP to cost approximately US$ 2 million. This directive was issued even though this 
portion of the lower Passaic River is a subject of the PRRP. The DEP has advised the recipients that (a) it is 
engaged in discussions with the EPA regarding the subject matter of the directive, and (b) they are not 
required to respond to the directive until otherwise notified. Additionally, in December 2005, the DEP sued 
YPF Holdings Inc., Tierra, Maxus and other several companies, besides to Occidental, in connection with 
the dioxin contamination allegedly emanating from Chemicals’ former Newark plant and contaminating the 
lower portion of the Passaic River, Newark Bay, other nearby waterways and surrounding areas. The DEP 
seeks remediation of natural resources damaged and punitive damages and other matters. The defendants 
have made responsive pleadings and filings. The Court denied motions to dismiss by Occidental Chemical 
Corporation, Tierra and Maxus. The DEP filed its Second Amended Complaint in April 2008. YPF filed a 

•

•  

•  

•  

motion to dismiss for lack of personal jurisdiction. The motion mentioned previously was denied in 
September, 2008, and the denial was confirmed by the Court of Appeal. Notwithstanding, the Court denied 
to plaintiffs’ motion to bar third party practice and allowed defendants to file third-party complaints. 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.  
In June 2007, EPA released a draft Focused Feasibility Study (the “FFS”) that outlines several alternatives 
for remedial action in the lower eight miles of the Passaic River. These alternatives range from no action, 
which would result in comparatively little cost, to extensive dredging and capping, which according to the 
draft FFS, EPA estimated could cost from US$ 0.9 billion to US$ 2.3 billion and are all described by EPA as 
involving proven technologies that could be carried out in the near term, without extensive research. Tierra, 
in conjunction with the other parties of the PRRP group, submitted comments on the legal and technical 
defects of the draft FFS to EPA, as did other interested parties. In light of these comments, EPA decided to 
initiate his review and informed that a revised remedy proposal will be forthcoming during the first quarter 
of 2011. Tierra will respond to any further EPA proposal as may be appropriate at that time.  
In August 2007, the National Oceanic Atmospheric Administration (“NOAA”) sent a letter to the parties of 
the PRRP group, including Tierra and Occidental, requesting that the group enters into an agreement to 
conduct a cooperative assessment of natural resources damages in the Passaic River and Newark Bay. The 
PRRP group has declined to do so at this time, citing concerns with matters such as the FFS being revised by 
EPA as described above. In January 2008, the NOAA sent a letter to YPF S.A., YPF Holdings Inc., CLH 
Holdings Inc. and other entities, designating them as potentially responsible parties (“PRP”). Such letters 
have been responded, rejecting the designation as PRP. In November 2008, Tierra 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, Tierra declined to extend this agreement for one additional year, citing 
concerns arising from the Passaic River litigation.  
In June 2008, the EPA, Occidental, and Tierra entered into an AOC, pursuant to which Tierra (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 will result in the removal of approximately 200,000 cubic yards of 
sediment, which will be carried out in two different phases. The first phase, which is scheduled to begin in 
2010, encompasses the removal of 40,000 cubic yards of sediments and is expected to be completed in nine 
months. The first phase estimated cost is approximately US$ 45 million. The second phase involves the 
removal of approximately 160,000 cubic yards of sediment. This second phase will start once the first phase 
is completed. Pursuant to the AOC, the EPA has required the constitution of a trust fund of US$ 80 million 
for the performance of the removal work. As of December 31, 2009, US$ 22 million have been deposited 
and an additional US$ 10 million must be contributed every six months, until the completion of the US$ 80 
million. Notwithstanding, during the first quarter of 2010, a letter of credit to provide financial assurance has 
been issued, in order to avoid the restriction of additional funds pursuant to the AOC. During the removal 
action, contaminants not produced by the former Diamond Alkali plant, such as PCBs and mercury, will 
necessarily be removed along with dioxin. Although having recognized the estimated costs related to all 
works mentioned above, YPF Holdings Inc. and its subsidiaries may seek cost recovery from the parties 
responsible for such contamination, provided contaminants’ origins were not from the Diamond Alkali 
plant. However, as of December 31, 2009, it is not possible to make any predictions regarding the likelihood 
of success or the funds potentially recoverable in a cost-recovery action.  

As of December 31, 2009, there are approximately 248 reserved, comprising the estimated costs for studies, the 
YPF Holdings Inc.’s best estimate of the cash flows it could incur in connection with remediation activities 
considering the studies performed by Tierra, the estimated costs related to the agreement, and in addition certain 
other matters related to Passaic River and the Newark Bay. However, it is possible that other works, including 
interim remedial measures, may be ordered. In addition, the development of new information on the imposition of 
natural resource damages, or remedial actions differing from the scenarios that YPF Holdings Inc. has evaluated 
could result in additional costs to the amount currently reserved.  
Hudson County, New Jersey. Until 1972, Chemicals operated a chromite ore processing plant at Kearny, New 
Jersey (“Kearny Plant”). According to the DEP, wastes from these ore processing operations were used as fill 
material at a number of sites in and near Hudson County. The DEP and Occidental, as successor to Chemicals, 
signed an administrative consent order with the DEP in 1990 for investigation and remediation work at certain 
chromite ore residue sites in Kearny and Secaucus, New Jersey.  

F - 30 

 
Tierra, on behalf of Occidental, is presently performing the work and funding Occidental’s share of the cost of 
investigation and remediation of these sites. In addition, financial assurance has been provided in the amount of 
US$ 20 million for performance of the work. The ultimate cost of remediation is uncertain. Tierra submitted its 
remedial investigation reports to the DEP in 2001, and the DEP continues to review the report.  
Additionally, in May 2005, the DEP took two actions in connection with the chrome sites in Hudson and Essex 
Counties. First, the DEP issued a directive to Maxus, Occidental and two other chromium manufacturers directing 
them to arrange for the cleanup of chromite ore residue at three sites in New Jersey City and the conduct of a study 
by paying the DEP a total of US$ 20 million. While YPF Holdings Inc. believes that Maxus is improperly named 
and there is little or no evidence that Chemicals’ chromite ore residue was sent to any of these sites, the DEP 
claims these companies are jointly and severally liable without regard to fault. Second, the State of New Jersey 
filed a lawsuit against Occidental and two other entities in state court in Hudson County seeking, among other 
things, cleanup of various sites where chromite ore residue is allegedly located, recovery of past costs incurred by 
the state at such sites (including in excess of US$ 2 million allegedly spent for investigations and studies) and, 
with respect to certain costs at 18 sites, treble damages. The DEP claims that the defendants are jointly and 
severally liable, without regard to fault, for much of the damages alleged. In February 2008, the parties reached an 
agreement for which Tierra will pay US$ 5 million and will perform remediation works in three sites, with a total 
cost of approximately US$ 2 million. As a result YPF Holdings Inc. has reserved 27 (which are included in the 
amount of 102 disclosed in the following paragraphs).  
In November 2005, several environmental groups sent a notice of intent to sue the owners of the properties 
adjacent to the former Kearny Plant (the “Adjacent Property”), including among others Tierra, under the Resource 
Conservation and Recovery Act. The stated purpose of the lawsuit, if filed, would be to require the noticed parties 
to carry out measures to abate alleged endangerments to health and the environment emanating from the Adjacent 
Property. The parties have entered into an agreement that addresses the concerns of the environmental groups, and 
these groups have agreed, at least for now, not to file suit.  
Pursuant to a request of the DEP, in the second half of 2006, Tierra and other parties tested the sediments in a 
portion of the Hackensack River near the former Kearny Plant. Tierra has submitted work plans for additional 
sampling requested by the DEP and is presently awaiting DEP comments.  
In March 2008, the DEP approved an interim response action work plan for work to be performed at the Kearny 
Plant by Tierra and the Adjacent Property by Tierra in conjunction with other parties. As a result YPF Holdings 
Inc. has reserved 29 (which are included in the amount of 102 disclosed in the following paragraphs).  
As of December 31, 2009, there are approximately 102 reserved in connection with the foregoing chrome-related 
matters. The study of the levels of chromium has not been finalized, and the DEP is still reviewing the proposed 
actions. The cost of addressing these chrome-related matters could increase depending upon the final soil actions, 
the DEP’s response to Tierra’s reports and other developments.  
Painesville, Ohio. In connection with the operation until 1976 of one chromite ore processing plant (“Chrome 
Plant”), from Chemicals, the Ohio Environmental Protection Agency (“OEPA”) ordered to conduct a RIFS at the 
former Painesville’s Plant area. Tierra has agreed to participate in the RIFS as required by the OEPA. Tierra 
submitted the remedial investigation report to the OEPA, which report was finalized in 2003. Tierra will submit 
required feasibility reports separately. In addition, the OEPA has approved certain work, including the remediation 
of specific sites within the former Painesville Works area and work associated with the development plans 
discussed below (the “Remediation Work”). The Remediation Work has begun. As the OEPA approves additional 
projects for the site of the former Painesville Works, additional amounts will need to be reserved.  
Over ten years ago, the former Painesville Works site was proposed for listing on the national Priority List under 
the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (“CERCLA”); 
however, the EPA has stated that the site will not be listed so long as it is satisfactorily addressed pursuant to the 
Director’s Order and OEPA’s programs. As of the date of issuance of these financial statements, the site has not 
been listed. YPF Holdings Inc. has reserved a total of 8 as of December 31, 2009 for its estimated share of the cost 
to perform the RIFS, the remediation work and other operation and maintenance activities at this site. The scope 
and nature of any further investigation or remediation that may be required cannot be determined at this time; 
however, as the RIFS progresses, YPF Holdings Inc. will continuously assess the condition of the Painesville’s 
plants works site and make any required changes, including additions, to its reserve as may be necessary.  
Third Party Sites. Pursuant to settlement agreements with the Port of Houston Authority and other parties, Tierra 
and Maxus are participating (on behalf of Chemicals) in the remediation of property required Chemicals’ former 
Greens Bayou facility where DDT and certain other chemicals were manufactured. Additionally, the parties have 
reached an agreement with the Federal and State Natural Resources Trustees concerning natural resources 
damages, which could require future additional contributions. As of December 31, 2009, YPF Holdings Inc. has 

F - 31 

 
reserved 32 for its estimated share of future remediation activities associated with the Greens Bayou facility. 
Although the primary work was completed in 2009, some follow-up activities and operation and maintenance 
remain pending.  
In June 2005, the EPA designated Maxus as a PRP at the Milwaukee Solvay Coke & Gas site in Milwaukee, 
Wisconsin. The basis for this designation is Maxus alleged status as the successor to Pickands Mather & Co. and 
Milwaukee Solvay Coke Co., companies that the EPA has asserted are former owners or operators of such site. 
Preliminary works in connection with the RIFS of this site commenced in the second half of 2006. YPF Holdings 
Inc. has reserved 10 as of December 31, 2009 for its estimated share of the costs of the RIFS. YPF Holdings Inc. 
lacks sufficient information to determine additional costs, if any; it might have in respect of this site.  
Maxus has agreed to defend Occidental, as successor to Chemicals, in respect of the Malone Services Company 
Superfund site in Galveston County, Texas. This site is a former waste disposal site where Chemicals is alleged to 
have sent waste products prior to September 1986. It is subject of enforcement activities by the EPA. Although 
Occidental is one of many PRPs that have been identified and have agreed to an AOC, Tierra (which is handling 
this matter on behalf of Maxus) presently believes the degree of Occidental’s alleged involvement as successor to 
Chemicals is relatively small. Chemicals has also been designated as a PRP with respect to a number of third party 
sites where hazardous substances from Chemicals’ plant operations allegedly were disposed or have come to be 
located. At several of these, Chemicals has no known vinculation. Although PRPs are typically jointly and 
severally liable for the cost of investigations, cleanups and other response costs, each has the right of contribution 
from other PRPs and, as a practical matter, cost sharing by PRPs is usually effected by agreement among them. As 
of December 31, 2009, YPF Holdings Inc. has reserved approximately 2 in connection with its estimated share of 
costs related to certain sites and the ultimate cost of other sites cannot be estimated at the present time.  
Black Lung Benefits Act Liabilities. The Black Lung Benefits Act provides monetary and medical benefits to 
miners disabled with a lung disease, and also provides benefits to the dependents of deceased miners if black lung 
disease caused or contributed to the miner’s death. As a result of the operations of its coal-mining subsidiaries, 
YPF Holdings Inc. is required to provide insurance of this benefit to former employees and their dependents. As of 
December 31, 2009, YPF Holdings Inc. has reserved 32 in connection with its estimate of these obligations.  
Legal Proceedings. In 2001, the Texas State Controller assessed Maxus approximately US$ 1 million in Texas 
state sales taxes for the period of September 1, 1995 through December 31, 1998, plus penalty and interest. In 
August 2004, the administrative law judge issued a decision affirming approximately US$ 1 million of such 
assessment, plus penalty and interest. YPF Holdings Inc. believes the decision is erroneous, but has paid the 
revised tax assessment, penalty and interest (a total of approximately US$ 2 million) under protest. Maxus filed a 
suit in Texas state court in December 2004 challenging the administrative decision. The matter will be reviewed 
by a trial de novo in the court action.  
In 2002, Occidental sued Maxus and Tierra in state court in Dallas, Texas seeking a declaration that Maxus and 
Tierra have the obligation under the agreement pursuant to which Maxus sold Chemicals to Occidental to defend 
and indemnify Occidental from and against certain historical obligations of Chemicals, including claims related to 
“Agent Orange” and Vinyl Chloride Monomer (“VCM”), notwithstanding the fact that said agreement contains a 
12-year cut-off for defense and indemnity obligations with respect to most litigation. Tierra was dismissed as a 
party, and the matter was tried in May 2006. The trial court decided that the 12-year cut-off period did not apply 
and entered judgment against Maxus. This decision was affirmed by the Court of Appeals in February 2008. 
Maxus has petitioned the Supreme Court of Texas for review. This lawsuit was denied. This decision will require 
Maxus to accept responsibility of various matters which it has refused indemnification since 1998 which could 
result in the incurrence of costs in addition to YPF Holdings Inc.’s current reserves for this matter. In March 2009, 
Maxus paid US$ 15 million to Occidental, and remains in discussions with Occidental regarding additional costs. 
As of December 31, 2009 YPF Holdings Inc. has reserved approximately 1 in respect to this matter.  
In March 2005, Maxus agreed to defend Occidental, as successor to Chemicals, in respect of an action seeking the 
contribution of costs incurred in connection with the remediation of the Turtle Bayou waste disposal site in Liberty 
County, Texas. The plaintiffs alleged that certain wastes attributable to Chemicals found their way to the Turtle 
Bayou site. Trial for this matter was bifurcated, and in the liability phase Occidental and other parties were found 
severally, and not jointly, liable for waste products disposed of at this site. Trial in the allocation phase of this 
matter was completed in the second quarter of 2007, and pursuant to the court decision, Maxus must pay on behalf 
of Occidental 15.96% of those costs incurred by one of the plaintiffs. That decision was appealed, and the parties 
are awaiting the court’s decision. As of December 31, 2009, YPF Holdings Inc. has reserved 14 in respect of this 
matter.

YPF Holdings Inc., including its subsidiaries, is a party to various other lawsuits and environmental situations, the 
outcomes of which are not expected to have a material adverse effect on YPF’s financial condition or its future 
results of operations. YPF Holdings Inc. reserves legal contingences and environmental situations that are 
probable and can be reasonably estimated.  

•   Tax claims:  

The Company has received several claims from the Administración Federal de Ingresos Públicos (“AFIP”) and 
from provincial and municipal fiscal authorities, which are not individually significant, and which have been 
reserved based on the best information available as of the date of the issuance of these financial statements.  
Additionally, YPF’s Management, in consultation with its external counsels, believes that the following contingencies and 
claims, individually significant, have possible outcome:  

•   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, and 
subsidiary constitution 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 summon 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 summon of the 
Argentine Government, due to its obligation to indemnify YPF for events and claims previous to 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 
of 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 third parties become involved.  

•   Dock Sud environmental claims: 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. At the 
moment, 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 previous to January 1, 1991, according to Law No. 24,145 and Decree 
No. 546/1993.  

By means of sentence dated July 8, 2008, the CSJN: 

(i)  Determined that the Basin Authority (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 Court of First Instance 
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”);  

(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 the CSJN. 

•   Other environmental claims in La Plata: On June 6, 2007, YPF was served with a new complaint in which 9 

residents of the vicinity of La Plata Refinery request: i) the cease of contamination and other harms they claim are 
attributable to the refinery; and ii) the clean-up of the adjacent channels, Río Santiago and Río de la Plata (soil, 
water and acquiferous, including those of the refinery) or, if clean-up is impossible, indemnification for 
environmental and personal damages. The plaintiff has quantified damages in 52 or an amount to be determined 
from evidence produced during the proceeding. YPF believes that most damages that are alleged by the plaintiff, 
might be attributable to events that occurred prior to YPF’s privatization and would, therefore, be covered to that 
extent by the indemnity granted by the Argentine Government in accordance with the Privatization Law of YPF. 

F - 33 

 
  
The Court has accepted the summon of the Argentine Government in this matter. Notwithstanding the foresaid, the 
possibility of YPF being asked to afford these liabilities is not discarded, in which case the Argentine Government 
must be asked to reimburse the remediation expenses for liabilities existing prior to January 1, 1991. In addition, 
the claim partially overlaps with the request made by a group of neighbors of La Plata Refinery on June 29, 1999, 
described in the first paragraph of “La Plata and Quilmes environmental claims”. Accordingly, YPF considers that 
the cases should be partially consolidated to the extent that the claims overlap. Regarding claims not consolidated, 
information and documents in order to answer the claim are being collected, and for the time being, it is not 
possible to reasonably estimate the outcome, as long as, if applicable, estimate the corresponding legal fees and 
expenses that might result. The contamination that may exist could derive from countless sources, including from 
disposal of waste over many years by other industrial facilities and ships.  
Additionally, YPF is aware of an action that has not been served yet, in which the plaintiff requests the clean-up of 
the channel adjacent to the La Plata Refinery, the Río Santiago, and other sectors near the coast line, and, if such 
remediation is not possible, an indemnification of 500 or an amount to be determined from evidence produced in 
discovery. The claim partially overlaps with the requests made by a group of neighbors of La Plata Refinery on 
June 29, 1999, described in the first paragraph of “La Plata and Quilmes environmental claims”, and with the 
complaint served on June 6, 2007, mentioned in the previous paragraph. Accordingly, YPF considers that if it is 
served in this proceeding or any other proceeding related to the same subject matters, the cases should be 
consolidated to the extent that the claims overlap. With respect to claims not consolidated, for the time being, it is 
not possible to reasonably estimate the monetary outcome, as long as, if applicable, estimate the corresponding 
legal fees and expenses that might result. Additionally, YPF believes that most damages alleged by the plaintiff, if 
proved, might be attributable to events that occurred prior to YPF’s privatization and would therefore be the 
responsibility of the Argentine Government in accordance with the Privatization Law concerning YPF.  

•   EDF International S.A. (“EDF”) claim: EDF had initiated an international arbitration proceeding under the 

Arbitration Regulations of the International Chamber of Commerce (“ICC”) against Endesa Internacional S.A. and 
YPF. EDF claimed from YPF the payment of US$ 69 million, which were subsequently increased to US$ 
103 million plus interests, without existing real arguments, in connection with the sale of Electricidad Argentina 
S.A., parent company of Edenor S.A. EDF claimed an adjustment in the purchase price it paid arguing that under 
the stock purchase agreement, the price it paid would be reviewed if changes in the exchange rate of Argentine 
peso occurred prior to December 31, 2001. EDF considered that this had happened. On October 22, 2007, the 
Arbitral Court issued an arbitral final award in which EDF’s claim and the defendants’ counterclaim were partially 
accepted. Consequently, the arbitral final award imposed on YPF the payment of US$ 28.9 million plus interests 
and judicial expenses. The Company and EDF both challenged the arbitral decision before the Argentine justice. 
On April 22, 2008, the Federal Court of Appeals on Commercial Matters declared that the appeal filed with by 
YPF has suspension effects on the arbitral decision. Nevertheless, EDF sought the enforcement of the arbitral 
decision before the Court of the District of Delaware, United States, which was rejected by the Company. The 
mentioned enforcement has been rejected by the First Instance Court. The Court of Appeals of United States 
partially overturned such decision and ordered the suspension of proceedings until the conclusion of the Argentine 
annulment proceedings, as required by YPF. Additionally YPF has been notified of the enforcement proceedings 
EDF has commenced in Paris, France.  
On December 9, 2009, the Court of Appeals on Commercial Matters declared the arbitral award void with regard 
to the payment imposed to Endesa Internacional S.A. and YPF in favor of EDF as well as the payment imposed to 
EDF in favor of Endesa Internacional S.A. and YPF. On February 8, 2010, the Company was notified of the 
extraordinary appeal filed by EDF against the decision of the Court of Appeals on Commercial Matters. The 
Supreme Court has rejected EDF’s extraordinary appeal and, consequently, EDF has presented a complaint appeal.  

•   Hydrocarbon’s concessions - Provincial claims: YPF has been notified of the Resolution No. 433/2008 issued by 
the Direction of Hydrocarbons, Ministry of Production of the Province of Río Negro, concerning compliance with 
certain obligations assumed as production concessionaire of the areas Barranca de los Loros, Bajo del Piche, El 
Medanito and Los Caldenes, all of them located in the Province of Río Negro. The resolution provides that YPF, 
among others, has not complied with certain obligations as production concessionaire and claims for damages to 
the environment.   
Considering the previous paragraph and the dispositions of the Law No. 17,319 (Law of Hydrocarbons), YPF was 
requested to submit its discharge at risk of termination of the mentioned concessions. However, the mentioned 
Law grants the concessionaire and/or licensee the right, prior to termination of the concession, to cure a 
contractual breach within a certain period of time after receiving notice thereof. In this order, on May 29, 2008, 
YPF filed a request for nullification of the Resolution No. 433/2008, since this resolution fail to grant YPF the 
mentioned right. Additionally, on June 13, 2008, YPF submitted a response, denying the mentioned charges. On 
November 12, 2008, the Ministry of Production ordered the initiation of the evidence production period. On 

F - 34 

 
  
November 28, 2008, YPF requested the production of certain evidence and the appointment of a technical expert. 
As of the issuance date of these financial statements, YPF has argued certain aspects related with the production of 
evidence. On May 12, 2009, the Company was notified of the issuance of Resolution No. 31/09, ordering a time 
extension in the evidence production period. On December 1, 2009, YPF filed with the requested documentary 
evidence and stated that certain aspects related to the evidence production period are still pending.  

•   Claims related to the gas market and others:  

In addition to the information described under the title “Natural gas market” in this note, and in relation to the 
existence of clients with whom YPF has commitments to deliver natural gas which, as a result of the Restrictions, 
the Company has been forced to suspend totally or partially the corresponding deliveries, invoking the existence of 
force majeure or fortuitous event, and which constitute in some cases contingencies with possible outcome, the 
Company is also involved in the following litigations related to the natural gas market:  

•   Arbitration process initiated by Transportadora de Gas del Mercosur S.A. (“TGM”): YPF was notified of an 

arbitration process brought by TGM against YPF before the ICC, claiming unpaid and outstanding invoices in an 
approximate amount of US$ 10 million plus interest, in connection with the payments of the invoices established 
in the natural gas transportation contract entered into in September 1998 between YPF and TGM, associated with 
the natural gas export contract entered into by YPF and AESU previously mentioned. On April 8, 2009, YPF 
requested the rejection of this claim and counterclaimed asking for the termination of the natural gas transportation 
contract, based on the termination promoted by AESU and Companhía de Gás do Estado do Río Grande do Sul 
(“Sulgás”) of the natural gas export contract. Additionally, YPF registered a request for arbitration at the ICC 
against TGM, amongst others. TGM answered the arbitral complaint by requesting the rejection of all YPF claims 
and filed a counterclaim against YPF asking the arbitral tribunal: i) that YPF indemnifies TGM for all of the 
present and future damages derived from the termination of the natural gas transportation contract and the 
agreement entered into between the parties on October 2, 1998, by which YPF had agreed to pay TGM non-
capitalizable irrevocable contributions as a compensation for the extension of the natural gas pipeline Proyecto 
Uruguayana; and ii) that AESU / Sulgás be severally obliged to indemnify TGM for all the damages caused to 
TGM derived from the termination of the natural gas supply contract, in case AESU or Sulgas are declared 
responsible for that termination. Additionally, on July 10, 2009, TGM increased the amounts of its claim to US$ 
17 million and claimed an additional amount of US$ 366 million as lost profit, a claim for which YPF believes it 
would not be responsible. YPF rejected TGM’s arguments. As of the date of the issuance of these financial 
statements, the Arbitration Tribunal has been constituted. The parties agreed on the Terms of Reference in 
coordination with the Arbitration Tribunal. On June 10, 2010, YPF submitted its arguments on procedural grounds 
before the Arbitration Tribunal and requested the Arbitration Tribunal to determine that it was not competent to 
hear this claim. In case such motion is rejected, YPF has requested the Arbitration Tribunal to suspend this 
arbitration until the ongoing arbitration with TGM, AESU and Sulgás is solved.  

•   Administrative presentation against Transportadora de Gas del Norte S.A. (“TGN”): On April 8, 2009, YPF filed 
a complaint against TGN before the ENARGAS, seeking the termination of the natural gas transportation contract 
with that company to transport natural gas associated with the natural gas export contract entered with AESU and 
other parties. The termination of the contract with TGN is based on: (a) the impossibility of YPF to use and of 
TGN to render the natural gas transportation service due to the conjunction of (i) the termination of the natural gas 
contract with Sulgás/AESU and (ii) the legal impossibility of assigning the transportation contract to other parties 
under current regulatory framework, (b) the legal impossibility of TGN to render the transportation service on a 
firm basis according to the terms of the contract as a consequence of certain changes in the regulatory framework 
since 2004, and (c) the Hardship Provision (teoría de la imprevisión) as defined under Argentine law, upon the 
existence of extraordinary events which caused an excessive burden.  

•   National Antitrust Protection Board: On November 17, 2003, Antitrust Board requested explanations, within the 
framework of an official investigation pursuant to Art. 29 of the Antitrust Law, from a group of almost thirty 
natural gas production companies, among them YPF, 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 Art. 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 

F - 35 

 
  
  
undertaken pursuant to the provisions of Section 30 of the Antitrust Law. On January 15, 2007, 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 Art. 
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 as a consequence of the appeal presented by YPF against the rejection of the application of the statute 
of limitations.  
In addition, YPF is subject to other claims before the Antitrust Board which are related to alleged price 
discrimination in sale of fuels. Management based on the evidence available to date and upon the opinion of its 
legal advisors, has considered them to be possible contingencies.  

•   Users and Consumers’ association claim: the “Users and Consumers Association” (Unión de Usuarios y 

Consumidores) claimed originally against Repsol YPF (then extending its claim to YPF) the reimbursement of the 
overprice allegedly charged to bottled LPG consumers between 1993 and 2001. The claim is for an unspecified 
sum, amounting to 91 in the period 1993 to 1997 (this sum, brought up-to-date would be approximately 304), 
together with an undetermined amount for the period 1997 to 2001. The Company claimed the application of the 
statute of limitations (as well as other defenses) since, at the date of the extension of the claim, the two-year limit 
had already elapsed. Notwithstanding, on August 6, 2009, the evidence production period commenced and the 
evidence is now being produced.  

•   Compañía Mega claim: Compañía Mega has claimed YPF for cutbacks in natural gas supply pursuant to their 

respective sales contract. YPF affirmed that the deliveries of natural gas to Mega were affected by the interference 
of the Argentine Government. Besides, YPF would not have any responsibility based on the events of force 
majeure and fortuitous case. Despite the fact that the Company has material arguments of defense, taking into 
account the characteristics of the claims, they have been considered as possible contingencies.  

•   Pluspetrol Energy S.A. contractual obligations: Pluspetrol Energy S.A. (“Pluspetrol”) and Gas Atacama 

Generación S.A. (“Gas Atacama”) had reached an agreement through which, in case that Pluspetrol could not 
fulfill its natural gas delivery obligations, it would indemnify Gas Atacama. This agreement would come into 
effect once ratified by the Secretariat of Energy. However, in March 10, 2008, the Ministry of Economy and 
Production issued Resolution No. 127/2008, by which natural gas export withholding rate was increased, 
significantly changing the commercial terms of the aforementioned agreement. Consequently, Pluspetrol informed 
Gas Atacama and the Secretariat of Energy its intention to terminate the aforementioned agreement. As a result, 
the parties initiated conversations in order to consider the new regulatory framework and reached a new agreement 
with a cap to the compensation Pluspetrol must pay to Gas Atacama in case it fails to deliver the committed 
volumes.  

Additionally, the Company 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 reserved since Management, based 
on the evidence available as of the date of issuance of these financial statements, has considered them to be possible 
contingencies.  

b)  Environmental liabilities:  

•  YPF is subject to various provincial and national 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 clean-up and environmental 
damages resulting from operations. Management believes that the Company’s operations are in substantial compliance with 
Argentine laws and regulations currently in force relating to the protection of the environment, as such laws have historically 
been interpreted and enforced.  
However, the Company is periodically conducting new studies to increase its knowledge concerning the environmental situation 
in certain geographic areas where the Company operates 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 Argentine Government, in accordance 
with the contingencies assumed by the Argentine Government for liabilities existing prior to December 31, 1990. Until these 
studies are completed and evaluated, the Company cannot estimate what additional costs, if any, will be required. However, it is 
possible that other works, including provisional remedial measures, may be required.  

F - 36 

 
  
In addition to the hydrocarbon wells abandonment legal obligations for 4,254 as of December 31, 2009, the Company has 
reserved 464 corresponding to environmental remediation, which evaluations and/or remediation works are probable, significant 
and can also be reasonably estimated, based on the Company’s existing remediation program. Legislative changes, on individual 
costs and/or technologies may cause a re-evaluation of the estimates. The Company 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, 
this potential changes and ongoing studies could materially affect future results of operations.  

c)  Contractual commitments and regulatory requirements:  

•  Contractual commitments: The Company has signed contracts by means of which it has committed to buy certain products and 

services, and to sell natural gas, liquefied petroleum gas and other products. Some of the mentioned contracts include penalty 
clauses that stipulate compensations for a breach of the obligation to receive, deliver or transport the product object of the 
contract. In particular, the Company has renegotiated certain natural gas export contracts, and has agreed certain limited 
compensations in case of any delivery interruption and/or suspension, for any reason, except for physical force majeure event. 
The estimated losses for contracts in progress, if any, considering the compensations mentioned above, are charged to the 
income of the year in which are identified.  

•  Natural gas regulatory requirements: In addition to the regulations that affect the natural gas market mentioned in “Natural gas 
market” (Note 10.a), on June 14, 2007, Resolution No. 599/2007 of the Secretariat of Energy was published in the Official 
Gazette (the “Resolution”). 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”). The purpose of this Agreement 
2007-2011 is to guarantee 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’s 
consumption (the “Priority Demand”).  

•   According to the Resolution, the producers that have signed the Agreement 2007-2011 commit to supply a part of the Priority 

• 

Demand according to certain percentage determined for each producer based upon its share of production for the 36 months 
period prior to April 2004. In case of shortage to supply Priority Demand, natural gas exports of producers that did not sign the 
Agreement 2007-2011 will be the first to be called upon in order to satisfy such mentioned shortage. The Agreement 2007-2011 
also establishes terms of effectiveness and pricing provisions for the Priority Demand consumption. Considering that the 
Resolution anticipates the continuity of the regulatory mechanisms that affect the exports, YPF has appealed the Resolution and 
has expressly stated that the execution of the Agreement 2007-2011 does not mean any recognition by YPF of the validity of 
that Resolution. On June 22, 2007, the National Direction of Hydrocarbons notified that the Agreement 2007-2011 reached the 
sufficient level of subscription.  
Liquid hydrocarbons regulatory requirements: Resolution No. 1,679/04 of the Secretariat of Energy 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, Resolution No. 1,338/06 of the Secretariat of Energy added other petroleum products to the registration regime created 
by Executive Decree No. 645/02, including gasoline, fuel oil and its derivatives, diesel, aviation fuel, asphalts, certain 
petrochemicals and certain lubricants. Resolution No. 715/07 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 exports of products included under the regime of Resolution No. 1,679/04; the fulfillment of this obligation to 
import diesel is necessary to obtain authorization to export the products included under Decree No. 645/02. In addition, 
Resolution No. 25/06 of the 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 fuel demand, by supplying certain minimum 
volumes (which at least 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 168/04 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.  
Other regulatory requirements: In connection with certain natural gas export contracts from the Noroeste basin in Argentina, 
YPF presented to the Secretariat of Energy the accreditation of the existence of natural gas reserves of that basin in adherence to 
export permits. In case the Secretariat of Energy considers that the natural gas reserves are insufficient, it could resolve the 
expiration or partial or total suspension of one or several export permits. The Secretariat of Energy limited preventively the 
exportable volumes of natural gas in a 20% by Note No. 1,009/2006. All of this is connected with the export authorization given 
by Resolution No. 167/1997 of the Secretariat of Energy (80% of the maximum exportable quantities still remain).  

F - 37 

 
  
During 2005, the Secretariat of Energy by means of Resolution No. 785/2005 modified by Resolution No. 266/2008 of the 
Ministry of Federal Planning, Public Investment and Services, created the National Program of Hydrocarbons and its derivatives 
Warehousing Aerial Tank Loss Control, measure aimed at reducing and correcting environmental pollution caused by 
hydrocarbons and its derivatives warehousing-aerial tanks. The Company has begun to develop and implement a technical and 
environmental audit plan as required by the resolution.  

•   Agreements for the extension of concessions:  

(i) 

Agreement with the Argentine Government and the Province of Neuquén of the year 2000: On December 28, 2000, 
through Decree No. 1,252/2000, the Argentine Federal Executive Branch (the “Federal Executive”) extended for an 
additional term of 10 years and until November 2027 the concession for the exploitation of Loma La Lata – Sierra Barrosa 
area granted to YPF. The extension was granted under the terms and conditions of the Extension Agreement executed 
between the Argentine Government, the Province of Neuquén and YPF on December 5, 2000. Under this agreement, YPF 
paid US$ 300 million to the Argentine Government for the extension of the concession mentioned above, which were 
recorded in “Fixed Assets” on the balance sheet and committed, among other things, to define a disbursement and 
investment program of US$ 8,000 million in the Province of Neuquén from 2000 to 2017 and to pay to the Province of 
Neuquén 5% of the net cash flows arising out of the concession during each year of the extension term. The previously 
mentioned commitments have been affected by the changes in economic rules established by Public Emergency and 
Exchange System Reform Law No. 25,561.  

(ii)  Agreement with the Province of Neuquén of the year 2008: In September, 2008, YPF entered into a Memorandum of

(iii)  Agreements with the Province of Neuquén of the year 2009:  

•   Aguada Pichana and San Roque: YPF, together with Total Austral S.A., Pan American Energy LLC Sucursal 

Argentina (“PAE”) and Wintershall Energía S.A. entered into a Memorandum of Agreement with the province of 
Neuquén, to extend until the year 2027 the term of Aguada Pichana and San Roque Concessions (the 
“Memorandum of Agreement AP and SR”).  
The aforementioned companies undertook the following commitments: i) to make a total initial payment of US$ 
88 million, paying each company on a pro rata basis based on its working interest in the area (US$ 26 million for 
YPF); ii) to pay in cash to the province an “Extraordinary Production Royalty” of 3% of the production of the

11. RESTRICTIONS ON UNAPPROPRIATED RETAINED EARNINGS  
In accordance with the provisions of Law No. 19,550, 5% of net income for each fiscal year has to be appropriated to the legal reserve 
until such reserve reaches 20% of the Company’s capital (subscribed capital plus adjustment to contributions). As of December 31, 
2009, the legal reserve has reached the 20% of the Social Capital amounting to 2,243.  

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, shall be subject to a 35% income tax withholding as a sole and 
final payment, except for those distributed to shareholders resident in countries benefited from treaties for the avoidance of double 
taxation, which will be subject to a minor tax rate.  

12. MAIN CHANGES IN COMPANIES COMPRISING THE YPF GROUP  
During the year ended December 31, 2007:  

•  YPF acquired an additional 18% interest in Oleoducto Trasandino (Argentina) S.A., an 18% interest in Oleoducto 

Trasandino (Chile) S.A. and an 18% interest in A&C Pipeline Holding Company, for an amount of US$ 5.3 million.  

•  YPF sold its interest in Petróleos Trasandinos S.A., for an amount of US$ 2.  

13. SUMMARY OF SIGNIFICANT DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES FOLLOWED BY THE 
COMPANY AND UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES  
The consolidated financial statements have been prepared in accordance with Argentine GAAP, which differs in certain respects from 
generally accepted accounting principles in the United States of America (“U.S. GAAP”).  

The differences between Argentine GAAP and U.S. GAAP are reflected in the amounts provided in Notes 14 and 15 and principally 
relate to the items discussed in the following paragraphs:  

a. 

Functional and reporting currency  

Under Argentine GAAP, financial statements are presented in constant Argentine pesos (“reporting currency”), as mentioned in Note 
1. Foreign currency transactions are recorded in Argentine pesos by applying to the foreign currency amount the exchange rate 
between the reporting and the foreign currency at the date of the transaction. Exchange rate differences arising on monetary items in 
foreign currency are recognized in the income statement of each year.  

Under U.S. GAAP, a definition of the functional currency is required, which may differ from the reporting currency. Management has 
determined for YPF and certain of its subsidiaries and investees the U.S. dollar as its functional currency in accordance with the 
Accounting Standard Codification (“ASC”) No. 830, “Foreign Currency translation” (“ASC No. 830”). Therefore, the Company has 
remeasured into U.S. dollars its financial statements and the financial statements of the mentioned subsidiaries and investees as of 
December 31, 2009, 2008 and 2007, prepared in accordance with Argentine GAAP by applying the procedures specified in ASC 
No. 830. The objective of the remeasurement process is to produce the same results that would have been reported if the accounting 
records had been kept in the functional currency. Accordingly, monetary assets and liabilities are remeasured at the balance sheet date 
(current) exchange rate. Amounts carried at prices in past transactions are remeasured at the exchange rates in effect when the 
transactions occurred. Revenues and expenses are remeasured on a monthly basis at the average rates of exchange in effect during the 
period, except for consumption of nonmonetary assets, which are remeasured at the rates of exchange in effect when the respective 
assets were acquired. Translation gains and losses on monetary assets and liabilities arising from the remeasurement are included in 
the determination of net income (loss) in the period such gains and losses arise. For certain YPF’s subsidiary and investees, 
Management has determined the Argentine peso as its functional currency. Translation adjustments resulting from the process of 
translating the financial statements of the mentioned subsidiary and investees into U.S. dollars are not included in determining net 
income and are reported in other comprehensive income (“OCI”) as a component of shareholders’ equity.

The amounts obtained from the process referred to above are translated into Argentine pesos following the provisions of ASC 
No. 830. Assets and liabilities were translated at the current selling exchange rate of Argentine pesos 3.80, 3.45 and 3.15 to US$ 1, as 
of December 31, 2009, 2008 and 2007, respectively. Revenues, expenses, gains and losses reported in the income statement are 
translated at the exchange rate existing at the time of each transaction or, if appropriate, at the weighted average of the exchange rates 
during the period. Translation effects of exchange rate changes are included in OCI as a component of shareholders’ equity.  

b. 

Proportional consolidation  

As discussed in Note 1, YPF has proportionally consolidated, net of intercompany transactions, assets, liabilities, revenues, income, 
costs and expenses of investees in which joint control is held. Under U.S. GAAP these investees are accounted for by the equity 
method. The mentioned proportional consolidation generated under Argentine GAAP an increase of 820, 648 and 486 in total assets 
and total liabilities as of December 31, 2009, 2008 and 2007, respectively, and an increase of 1,433, 1,770 and 1,350 in net sales and 
551, 681, and 690 in operating income for the years ended December 31, 2009, 2008 and 2007, respectively.  

c. 

Valuation of inventories  

As described in Note 2.b, the Company values its inventories of refined products for sale, products in process of refining and 
separation, crude oil and natural gas at replacement cost provided that does not exceed net realizable value. Under U.S. GAAP, these 
inventories should be valued at the lower of cost or market, which is defined as replacement cost, provided that it does not exceed net 
realizable value or is not less than net realizable value reduced by a normal profit margin. As the turnover ratio of inventories is high, 
there have been no significant differences between inventories valued at replacement cost and at historical cost using first in first out 
(“FIFO”) method for the years presented.  

d. 

Impairment of long-lived assets  

Under Argentine GAAP, in order to perform the recoverability test, long-lived assets are grouped with other assets at business 
segment level (see Note 8). With respect to long-lived assets that are held as pending for sale or disposal, the Company’s policy is to 
record these assets at amounts that did not exceed net realizable value.  

Under U.S. GAAP, until December 31, 2008, for proved oil and gas properties the Company performed the impairment test on an 
individual field basis. From January 2009, the Company has reassessed its proved oil and gas properties’ grouping for impairment 
purposes, as a consequence of certain regulatory developments that have been implemented in Argentina during recent periods that 
have also affected its operation (Note 10.c). As a consequence of this reassessment from January 1, 2009, oil properties are grouped 
into a unique cash generating unit and gas properties are grouped by basin, considering logistics restrictions. Impairment charges 
recorded until December 31, 2008, has not been reversed, therefore, the modification in the long-lived asset grouping has not had any 
effect in the operation results for the year ended December 31, 2009. Other long-lived assets are aggregated, so that the discrete cash 
flows produced by each group of assets may be separately analyzed. Each asset is tested following the guidelines of ASC No. 360, 
“Accounting for the Impairment of Long-Lived Assets”, by comparing the net book value of such an asset with the expected 
undiscounted cash flow. If the book value exceeds the expected undiscounted cash flow, then the impairment losses are measured as 
the amount by which the carrying amount of the assets exceeds the fair value of the assets. When market values are not available, the 
Company estimates them using the expected future cash flows discounted at a rate commensurate with the risks associated with the 
recovery of the assets.  

There were no impairment charges under U.S. GAAP for the year ended December 31, 2009. Additional impairment charges under 
U.S. GAAP amounted to 124 and 180 for the years ended December 31, 2008 and 2007, respectively, and were included as operating 
income from continuing operations. The impairment recorded in years ended December 31, 2008 and 2007 was mainly the result of a 
decrease in oil and gas reserves affecting certain long-lived assets of the YPF’s Exploration and Production Business Segment.  

The adjusted basis of fixed assets book values after impairment charges results in lower depreciation under U.S. GAAP of 173, 119 
and 132 for the years ended December 31, 2009, 2008 and 2007, respectively.  

e. 

Reorganization of entities under common control  

Under Argentine GAAP, results on sales of noncurrent assets and the corresponding accounts receivable are recognized in the 
statement of income and the balance sheet, respectively. Under U.S. GAAP, results on sales of noncurrent assets to entities under 
common control (within the Repsol YPF Group) are eliminated and the corresponding accounts receivable are considered as a capital 
(dividend) transaction.  

During the year ended December 31, 2007, the Company collected the account receivables related with the reorganization of entities 
under common control. Accordingly, no shareholders’ equity adjustment is required as of December 31, 2009, 2008 and 2007. Net 
income reconciliation for the year ended December 31, 2007, include the elimination of interests accrued under Argentine GAAP in 
relation with the mentioned account receivables, which should not be recognized under U.S. GAAP.

f. 

Pension Plans  

As displayed in Note 2.e, YPF Holdings Inc. has non-contributory defined-benefit pension plans and postretirement and 
postemployment benefits (“pension plans”).  

Under Argentine GAAP, as of December 31, 2009, the Company fully recognized the underfunded status of pension plans as a 
liability. The actuarial losses were charged to the “Other income (expense), net” account of the statement of income. Until 
December 31, 2008, the unrecognized actuarial losses were deferred and recorded in the statement of income during the expected 
average service period of the employees participating in the plans and the life expectancy of retired employees. The effect on net 
income related to the change in the accounting recognition criteria for losses and gains due to changes in actuarial assumptions for the 
years ended December 31, 2008 and 2007 is not material.  

Under U.S. GAAP the Company adopted SFAS No. 158 “Employers’ Accounting for Defined Benefit Pension and Other 
Postretirement Plans-an amendment of FASB Statements No. 87, 88, 106, and 132 (R)” codified into ASC No. 320. Under provisions 
of SFAS No. 158 the Company fully recognized the underfunded status of defined-benefit pension and postretirement plans as a 
liability in the financial statements reducing the Company’s shareholders’ equity through Accumulated OCI account. Unrecognized 
actuarial losses and gains are recognized in the statement of income during the expected average remaining service period of the 
employees participating in the plans and the life expectancy of retired employees.  

g. 

Accounting for asset retirement obligations  

ASC No. 410, “Accounting for Asset Retirement Obligations” (“ASC No. 410”), addresses financial accounting and reporting for 
obligations associated with the retirement of tangible long-lived assets and the associated asset retirement cost. The standard applies to 
legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development and 
normal use of the asset. ASC No. 410 requires that the fair value of a liability for an asset retirement obligation be recognized in the 
period in which it is incurred, if a reasonable estimate of fair value can be made. The asset retirement obligations liability is built up in 
cash flow layers, with each layer being discounted using the discount rate as of the date that the layer was created. Measurement of the 
entire obligation using current discount rates is not permitted. Each cash flow layer is added to the carrying amount of the associated 
asset. This additional carrying amount is then depreciated over the life of the asset. The liability is increased due to the passage of time 
based on the time value of money (“accretion expense”) until the obligation is settled. The activity with respect to retirement 
obligations under US GAAP is detailed in Note 15.c.  

Argentine GAAP is similar to ASC No. 410, except for a change in the discount rate which is treated as a change in estimates, so the 
entire liability must be recalculated using the current discount rate, being the change added or reduced from the related asset.  

h.  Consolidation of variable interest entities—Interpretation of ARB No. 51  
Under Argentine GAAP consolidation is based on having the votes necessary to control corporate decisions (Note 1). FIN 46R, 
“Consolidation of Variable Interest Entities”, codified into ASC No. 810, clarifies the application of Accounting Research Bulletin 
No. 51, Consolidated Financial Statements, to certain entities in which equity investors do not have the characteristics of a controlling 
financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial 
support from other parties. The interpretations explain how to identify variable interest entities and how an enterprise assesses its 
interests in a variable interest entity to decide whether to consolidate that entity. They require existing unconsolidated variable interest 
entities to be consolidated by their primary beneficiaries if the entities do not effectively disperse risks among parties involved.  

Until May, 2008, YPF had operations with one variable interest entity (“VIE”) which had been created in order to structure YPF’s 
future deliveries of oil (“FOS transaction”).  

YPF entered into a forward oil sale agreement that called for the future delivery of oil for the life of the contract. YPF was paid in 
advance for the future delivery of oil. The price of the oil to be delivered was calculated using various factors, including the expected 
future price and quality of the crude oil being delivered. The counterparty or assignee to the oil supply agreement was a VIE 
incorporated in the Cayman Islands, which financed itself through the issuance of notes. The oil to be delivered under the supply 
agreement was subsequently sold in the open market.  

YPF was exposed to any change in the price of the crude oil it will deliver in the future under the outstanding FOS transaction. YPF’s 
exposure derived from crude oil swap agreement under which YPF paid a fixed price with respect to the nominal amount of the crude 
oil sold, and received the variable market price of such crude oil.  

In May 2008, YPF delivered the last barrels committed under the FOS transaction; consequently the transaction and the swap 
agreement expired. As of December 31, 2009 and 2008, no shareholder’s equity reconciliation adjustment is required.  

The effect before taxes of such consolidation was an increase in the “Loans” account of 68, an increase of current assets of 24, the 
elimination of “Net advances from crude oil purchasers” of 9 and a decrease in shareholders’ equity of 35 as of December 31, 2007.

i. 

Capitalization of financial expenses  

Under Argentine GAAP, for those assets that necessarily take a substantial period of time to get ready for its intended use, borrowing 
costs (including interest and exchange differences) should be capitalized. Accordingly, borrowing costs for those assets whose 
construction period exceeds one year have been capitalized, provided that such capitalization does not exceed the amount of financial 
expense recorded in that year.  

Under US GAAP, interest expense on qualifying assets must be capitalized, regardless of the asset’s construction period.  

The effect on net income and shareholders’ equity as of December 31, 2009, 2008 and 2007 is included in “Capitalization of financial 
expenses” in the reconciliation in Note 14.  

The adjusted basis of fixed assets results in higher depreciation under U.S. GAAP of 57, 47 and 41 for the years ended December 31, 
2009, 2008 and 2007, respectively.

SFAS No.141(R), “Business Combinations” and SFAS No. 160, “Noncontrolling Interests in Consolidated Financial 
Statements — an amendment of ARB No. 51”, codified into ASC No. 810  

In December 2007, the FASB issued SFAS No. 141 (Revised 2007), “Business Combinations” (“SFAS No. 141(R)”) which requires 
the recognition of assets acquired, liabilities assumed, and any noncontrolling interest in an acquiree at the acquisition date, measured 
at their fair value as of that date, with limited exceptions. SFAS No. 141(R) changed the accounting treatment for certain specific 
items and includes a substantial number of new disclosure requirements. SFAS No. 141(R) applies prospectively to business 
combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after 
December 15, 2008. Since the Company has not been involved in any business combinations, the adoption of this standard had no 
impact to the Company’s result of operations, financial position or cash flows.  

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements — an 
Amendment of ARB No. 51” (“SFAS No. 160”), which establishes new accounting and reporting standards for noncontrolling interest 
(minority interest) and for the deconsolidation of a subsidiary. SFAS No. 160 also includes expanded disclosure requirements 
regarding the interests of the parent and its noncontrolling interest. SFAS No. 160 is effective for fiscal years, and interim periods 
within those fiscal years, beginning on or after December 15, 2008. The adoption of this statement had no significant effect in the 
Company’s results of operations, financial position or cash flows.  

k. 

SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, codified into ASC No. 815  
In March 2008 the FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities”. The new 
standard is intended to improve financial reporting about derivative instruments and hedging activities by requiring enhanced 
disclosures to enable investors to better understand their effects on an entity’s financial position, financial performance, and cash 
flows. The new standard also improves transparency about the location and amounts of derivative instruments in an entity’s financial 
statements; how derivative instruments and related hedged items are accounted for under SFAS 133; and how derivative instruments 
and related hedged items affect its financial position, financial performance, and cash flows. This Statement is effective for financial 
statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. As the 
Company has not any Derivative Instrument and Hedging Activities, this statement had no impact to the Company’s results of 
operations, financial position or cash flows.  

l. 

SFAS No. 165, Subsequent Events, codified into ASC No. 855  

In May 2009, the FASB issued SFAS No. 165, which establishes general standards of accounting for, and requires disclosure of, 
events that occur after the balance sheet date but before financial statements are issued or are available to be issued. The Company 
adopted the provisions of SFAS No. 165 as of December 31, 2009. The adoption of SFAS No. 165 did not have a material effect on 
the condensed consolidated financial statements.  

m. 

SFAS No. 168, “The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting 
Principles - a replacement of SFAS No. 162”, codified into ASC No. 105  

In June 2009, the FASB issued SFAS No. 168 which replaces SFAS No. 162, “The Hierarchy of Generally Accepted Accounting 
Principles” and establishes the FASB Accounting Standard Codification (“Codification”) as the source of authoritative accounting 
principles recognized by the FASB to be applied by nongovernmental entities in the preparation of financial statements in conformity 
with generally accepted accounting principles in the United States. SFAS No. 168 was prospectively effective for financial statements 
issued for fiscal years ending on or after September 15, 2009 and interim periods within those fiscal years. The adoption of SFAS 
No. 168 did not impact the Company’s results of operations or financial condition. The Codification did not change GAAP, however, 
it did change the way GAAP is organized and presented. As a result, these changes impact how companies reference GAAP in their 
financial statements and in their significant accounting policies. The Company implemented the codification in this Report by 
providing references to the codification topics alongside references to the corresponding standards.

n.  Modernization of Oil and Gas Reporting (Release Nos. 33-8995; 34-59192; FR-78)  
On December 31, 2008, the SEC published the final rules and interpretations updating its oil and gas reporting requirements (“SEC 
Final Rule”). Many of the revisions are updates to definitions in the existing oil and gas rules to make them consistent with the 
petroleum resource management system, which is a widely accepted standard for the management of petroleum resources that was 
developed by several industry organizations. Key revisions include changes to the pricing used to estimate reserves, the ability to 
include non-traditional resources in reserves, the use of new technology for determining reserves, and permitting disclosure of 
probable and possible reserves. The SEC required companies to comply with the amended disclosure requirements for registration 
statements filed after January 1, 2010, and for annual reports for fiscal years ending on or after December 31, 2009. Early adoption 
was not permitted. Additionally, in January 2010, the FASB issued ASU No. 2010-03, “Oil & Gas Reserves. Estimation and 
Disclosures” in order to align the current estimation and disclosure requirements with the requirements in the SEC Final Rule. The 
Company adopted the new requirements effective December 31, 2009. This adoption did not have a material impact on the 
Company’s reported reserves evaluation, results of operations, financial position or cash flows.  

14. RECONCILIATION OF NET INCOME AND SHAREHOLDERS’ EQUITY TO UNITED STATES GENERALLY 
ACCEPTED ACCOUNTING PRINCIPLES  
The following is a summary of the significant adjustments to net income for each of the years ended December 31, 2009, 2008 and

(2)  Cash and equivalents from jointly controlled companies which are proportionally consolidated for Argentine GAAP purposes 

are not included.  

The principal financing and investing transactions not affecting cash and equivalents consisted in increases in assets related to 
revisions in hydrocarbon well abandonment costs for the years ended December 31, 2009, 2008 and 2007 and the acquisitions during 
the years ended December 31, 2009 and 2008, of mineral property in connection with the extension of certain production concessions 
in the Province of Neuquén (Note 10.c.ii and iii), which is payable in installments through 2009 and 2010.  

15. ADDITIONAL U.S. GAAP DISCLOSURES  
a)  Consolidated operating income  
Under U.S. GAAP, costs charged to income for YPF Holdings environmental remediation, holding gains on inventories, impairment 
of long-lived assets, operating income from jointly controlled companies proportionally consolidated, pending lawsuits and other 
claims costs and other items which are not individually significant, would have been deducted from or added to operating income.

c)  Assets retirement obligation  
Under Argentine regulations, the Company has the obligation to incur costs related to the abandonment of hydrocarbon wells. The 
Company does not have assets legally restricted for purposes of settling the obligation.  

The reconciliation of the beginning and ending aggregate carrying amount of assets retirement obligation, translated into Argentine 
pesos at the outstanding selling exchange rate at the end of each year and under US GAAP, is as follows:  

Aggregate assets retirement obligation, beginning of year .....................................................................
Translation effect ....................................................................................................................................
Revision in estimated cash flows ............................................................................................................
Obligations incurred ...............................................................................................................................
Accretion expense...................................................................................................................................

Fair Value Measurements  

In September 2006, FASB issued SFAS No. 157, Fair Value Measurements codified into ASC No. 820, which became effective for 
the Company on January 1, 2008. ASC No. 820 defines fair value, establishes a framework for measuring fair value and expands 
disclosure requirements about fair value measurements. ASC No. 820 does not mandate any new fair-value measurements and is 
applicable to assets and liabilities that are required to be recorded at fair value under other accounting pronouncements. 
Implementation of this standard did not have a material effect on the Company’s results of operations or consolidated financial 
position.  

SFAS No. 157 establishes three levels of the fair-value hierarchy based on the sources of the inputs used in the measurement of the 
fair value, which are described below:  

Level 1: Quoted prices (unadjusted) in active markets for identical assets and liabilities.  

Level 2: Inputs other than Level 1 that are observable, either directly or indirectly.  

Level 3: Unobservable inputs.  

The initial application of SFAS No. 157 on January 1, 2008, had no effect on the Company’s existing fair-value measurement 
practices and is limited to the Company’s investments in mutual funds. The fair value measurements for these assets are based on 
observable market inputs (Level 1) consisting in quotations provided by the mutual funds’ bank sponsor. The fair value of these assets 
is 653 as of December 31, 2009, and the related gains or losses from periodic measurement at fair value is immaterial to the 
Company’s financial statements.  

In February 2008, the FASB issued FASB Staff Position (“FSP”) SFAS No. 157-1, Application of FASB Statement No. 157 to FASB 
Statement No. 13 and Its Related Interpretive Accounting Pronouncements That Address Leasing Transactions (“FSP 157-1”), which 
became effective for the Company on January 1, 2008. This FSP excludes SFAS No. 13, Accounting for Leases, and its related 
interpretive accounting pronouncements from the provisions of SFAS 157.

Also in February 2008, the FASB issued FSP SFAS 157-2, Effective Date of FASB Statement No. 157, which delayed the Company’s 
application of SFAS 157 for nonrecurring non financial assets and liabilities until January 1, 2009. As of December 31, 2009, there are 
not financial assets or liabilities measured at fair value.  

e) 

SFAS Interpretation No. 48, “Accounting for uncertainty in income taxes – an interpretation of FASB Statement 
No. 109” (“FIN 48”), codified into ASC No. 740  

FIN 48 defines the criteria an individual tax position must meet for any part of the benefit of such position to be recognized in the 
financial statements. FIN 48 establishes “a more-likely-than-not” recognition threshold that must be met before a tax benefit can be 
recognized in the financial statements. FIN 48 also provides guidance, among other things, on the measurement of the income tax 
benefit associated with uncertain tax positions, de-recognition, classification, interest and penalties and financial statement disclosures.  

There were no unrecognized tax benefits as of December 31, 2009, 2008 and 2007.  

Under Argentine tax regime, as of December 31, 2009, fiscal years 2002 through 2008 remain to examination by the Federal 
Administration of Public Revenues (“AFIP”).

Results of operations from oil and gas producing activities  
The following tables include only the revenues and expenses directly associated with oil and gas producing activities. It does not 
include any allocation of the interest costs or corporate overhead and, therefore, is not necessarily indicative of the contribution to net 
earnings of the oil and gas operations.  

Differences between these tables and the amounts shown in Note 8, “Consolidated Business Segment Information”, for the exploration 
and production business unit, relate to additional operations that do not arise from those properties held by the Company.

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.  

In accordance with the SEC’s new rules and FASB’s ASC 932 as amended (see Note 13.n), information on net proved reserves as of 
December 31, 2009 was calculated using the average price during the 12-month period ending on December 31, 2009, determined as 
an unweighted average of the first-day-of-the-month price for each month of that period. Information on net proved reserves as of 
December 31, 2008 and 2007 was calculated using year-end prices and costs, respectively.  

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 crude oil and natural gas liquids.  

YPF’s estimated proved reserves as of December 31, 2009, 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, surface geological 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.  

The use of new reliable technology as well as the change to an average of the first-day of the month prices from year-end prices to 
calculate proved reserves did not have any material impact on YPF’s proved reserves volumes in 2009.

(1)  Excludes quantities which have been flared or vented.  
(2)  Natural gas production for the years 2009, 2008 and 2007 includes approximately 56, 69 and 72, respectively, of gas equivalent 

to the royalties, whether payable in cash or in kind, where the royalty owner has not a direct interest in the underlying 
production and the option and ability to make lifting and sale arrangement independently.  

(3)  Proved reserves of natural gas as of December 31, 2009, 2008 and 2007, include approximately 280, 377 and 423, respectively, 
of natural gas equivalent to royalties, whether payable in cash or in kind, where the royalty owner has not a direct interest in the 
underlying production and the option and ability to make lifting and sale arrangement independently.  

Standardized measure of discounted future net cash flows  
The standardized measure is calculated as the excess of future cash inflows from proved reserves less future costs of producing and 
developing the reserves, future income taxes and a discount factor. Future cash inflows represent the revenues that would be received 
from production of year-end proved reserve quantities assuming the future production would be sold at year-end prices. Additionally, 
year-end prices were adjusted in those instances where future sales are covered by contracts at specified prices.

Future production costs include the estimated expenditures related to production of the proved reserves plus any production taxes 
without consideration of future inflation. Future development costs include the estimated costs of drilling development wells and 
installation of production facilities, plus the net costs associated with dismantling and abandonment of wells, assuming year-end costs 
continue without consideration of future inflation. Future income taxes were determined by applying statutory rates to future cash 
inflows less future production costs and less tax depreciation of the properties involved. The present value was determined by 
applying a discount rate of 10% per year to the annual future net cash flows.  

The future cash inflows and outflows in foreign currency have been remeasured at the selling exchange rate of Argentine pesos 3.80, 
3.45 and 3.15 to US$ 1, as of December 31, 2009, 2008 and 2007, respectively.  

The standardized measure does not purport to be an estimate of the fair market value of the Company’s proved reserves. An estimate 
of fair value would also take into account, among other things, the expected recovery of reserves in excess of proved reserves, 
anticipated changes in future prices and costs and a discount factor representative of the time value of money and the risks inherent in 
producing oil and gas.

de la Sociedad;  
Transferir a terceros, la totalidad de los derechos de explotación concedidos en el marco de la Ley 17.319, sus

voto (ya sea transitoria o permanentemente) lo harán, en su caso, como integrantes, a ese efecto, de la clase a la cual 
pertenezcan.

a) 

toda otra delegación admitida por la ley. Toda emisión de acciones ordinarias o preferidas se hará por clases respetando la 
proporción existente entre las distintas clases a la fecha de esa emisión, sin perjuicio de las modificaciones que ulteriormente 
resulten del ejercicio del derecho de preferencia y del derecho de acrecer según se prevé en el artículo 8° de este Estatuto.  

Acciones escriturales: Las acciones no se representarán en títulos sino que serán escriturales y se inscribirán en cuentas 
llevadas a nombre de sus titulares en la Sociedad, bancos comerciales, de inversión o cajas de valores autorizados, según lo 
disponga el directorio. Las acciones son indivisibles. Si existiese copropiedad, la representación para el ejercicio de los 
derechos o el cumplimiento de las obligaciones deberá unificarse.  
Transferencia de acciones clase A o C: Toda transferencia de acciones clase A efectuada en violación de lo dispuesto por el 
último párrafo de artículo 8° de la Ley 24.145, o de acciones clase C efectuada en violación de las normas del Programa de 
Propiedad Participada o del respectivo Acuerdo General de Transferencia comunicado fehacientemente a la Sociedad, será 
nula, carecerá de todo efecto y no será reconocida por la Sociedad.  
Deber de información: Toda persona que, directa o indirectamente, adquiera por cualquier medio o título, acciones clase D, o 
que al transferirse se conviertan en clase D, o títulos de la Sociedad de cualquier tipo que sean convertibles en acciones clase 
D (incluyendo, dentro del significado del término “título”, pero sin limitarse, a los debentures, obligaciones negociables y 
cupones de acciones) que otorguen control sobre más del tres por ciento (3%) de las acciones de la clase D, deberá dentro de 
los cinco (5) días de efectuada la adquisición que causó la superación de dicho límite, informar esa circunstancia a la 
Sociedad, sin perjuicio de cumplir con los recaudos adicionales que las normas aplicables en los mercados de capitales 
impongan para tal evento. La información referida deberá detallar, además, la fecha de la operación, el precio, el número de 
acciones adquiridas y si es propósito del adquirente de esa participación adquirir una participación mayor o alcanzar el 
control de la voluntad social de la Sociedad. Si el adquirente está conformado por un grupo de personas, deberá identificar 
los miembros del grupo. La información aquí prevista deberá proporcionarse con relación a adquisiciones posteriores a la 
informada originariamente brindada, cuando se vuelva a exceder, según lo aquí previsto, los montos de acciones clase D 
indicados en la última información.  
Toma de control: Sin cumplirse con lo indicado en los incisos e) y f) de este artículo no podrán adquirirse, directa o 
indirectamente, por cualquier medio o título, acciones de la Sociedad o títulos de la Sociedad (incluyendo dentro del 
significado del término “título”, pero sin limitarse, a los debentures, obligaciones negociables y cupones de acciones) 
convertibles en acciones cuando, como consecuencia de dicha adquisición, el adquirente resulte titular de, o ejerza el control 
sobre acciones Clase D de la Sociedad que, sumadas a sus tenencias anteriores de dicha clase (si las hubiere) representen, en 
total, el QUINCE POR CIENTO (15%) o más del capital social, o el VEINTE POR CIENTO (20%) o más de las acciones 
clase D en circulación, si las acciones representativas de dicho VEINTE POR CIENTO (20%) constituyeran, al mismo 
tiempo, menos del QUINCE POR CIENTO (15%) del capital social.  

No obstante lo indicado: (i) estarán excluidas de las previsiones de los incisos e) y f) de este artículo, las adquisiciones que 
realice quien ya sea titular o ejerza el control de acciones que representen más del CINCUENTA POR CIENTO (50%) del 
capital social; y (ii) estarán excluidas de las previsiones del inciso e) punto (ii) y del inciso f) de este artículo, las 
adquisiciones posteriores que realice quien ya sea titular o ejerza el control de acciones que representen el QUINCE POR 
CIENTO (15%) o más del capital social, o el VEINTE POR CIENTO (20%) o más de las acciones clase D en circulación, si 
las acciones representativas de dicho VEINTE POR CIENTO (20%) constituyeran, al mismo tiempo, menos del QUINCE 
POR CIENTO (15%) del capital social, siempre que las acciones de las que fuera y/o pase a ser titular el adquirente 
(incluyendo las acciones de las que fuera titular al momento de la adquisición y de las que pase a ser titular en virtud de la 
misma) no superen el CINCUENTA POR CIENTO (50%) del capital social.  
Las adquisiciones a las que se refiere este inciso d) se denominan “Adquisiciones de control”.

Realizar una oferta pública de adquisición de todas las acciones de todas las clases de la Sociedad y de todos los

Toda decisión que la asamblea especial de la clase A adopte en relación con las materias previstas en este inciso e) será 
definitiva y no generará derecho a indemnización alguna para ninguna parte.  
Oferta Pública de Adquisición: Cada oferta pública de adquisición será realizada de acuerdo con el procedimiento indicado 
en este inciso y, en la medida que las normas aplicables en las jurisdicciones en que la oferta pública de adquisición sea 
hecha y las disposiciones de las bolsas y mercados de valores en donde coticen las acciones y títulos de la Sociedad

celebrarse a los diez días hábiles contados a partir de la recepción por la Sociedad del aviso indicado en el 
subinciso (i), a fin de considerar la aprobación de la oferta pública de adquisición y someterá a dicha Asamblea su 
recomendación al respecto. Si tal asamblea no se celebra pese a la convocatoria, o si se celebrara y en ella se 
rechazara la oferta pública de adquisición, ésta no podrá cumplirse y tampoco se llevará a cabo el Acuerdo Previo, 
si existiera.  
La Sociedad enviará por correo, a cada accionista o tenedor de títulos convertibles en acciones, a costa del 
Oferente, con la diligencia razonable, copia de la notificación entregada a la Sociedad de acuerdo con lo indicado 
en el subinciso (i). El Oferente deberá adelantar a la Sociedad los fondos requeridos para este fin.  
El Oferente enviará por correo o de otra forma suministrará, con una diligencia razonable, a cada accionista o 
tenedor de títulos convertibles en acciones que se lo requiera, copia de la notificación suministrada a la Sociedad y 
publicará un aviso conteniendo sustancialmente la información indicada en el subinciso (i), al menos una vez por 
semana, comenzando en la fecha en que dicha notificación es entregada a la Sociedad de acuerdo con el subinciso 
(i) y terminando al expirar la fecha para la oferta pública de adquisición. Sujeto a las disposiciones legales 
aplicables, esta publicación se hará en la sección de negocios de diarios de circulación general en la República 
Argentina, en la ciudad de Nueva York, EE.UU. y en cualquier otra ciudad en cuya bolsa o mercado coticen las 
acciones.  
La contraprestación por cada acción o título convertible en acción pagadera a cada accionista o tenedor del título 
será la misma, en dinero, y no será inferior al precio por acción clase D o en su caso título convertible en acción 
clase D, más alto de los precios siguientes:  
(A) 

el mayor precio por acción o título pagado por el Oferente, o por cuenta del Oferente, en relación con 
cualquier adquisición de acciones clase D o títulos convertibles en acciones clase D dentro del período de 
dos años inmediatamente anterior al aviso de la adquisición de Control, ajustado a raíz de cualquier 
división accionaria, dividendo en acciones, subdivisión o reclasificación que afecte o se relacione a la 
clase D de acciones; o  
El precio más alto cierre vendedor durante el período de treinta días inmediatamente precedente a dicho 
aviso, de una acción clase D según su cotización en la Bolsa de Comercio de Buenos Aires, en cada caso 
ajustado a raíz de cualquier división accionaria, dividendo en acciones, subdivisión o reclasificación que 
afecte o se relacione a la clase D de acciones; o  

(B)

(C) 

(D) 

Un precio por acción igual al precio de mercado por acción de la clase D determinado según lo indicado 
en el subinciso (B) de esta cláusula multiplicado por la relación entre: (a) el precio por acción más alto 
pagado por el Oferente o por cuenta del mismo, por cualquier acción de la clase D, en cualquier 
adquisición de acciones de la clase dentro de los dos años inmediatamente precedentes a la fecha del 
aviso indicado en el subinciso (i), y (b) dicho precio de mercado por acción de la clase D en el día 
inmediatamente precedente al primer día del período de dos años en el cual el Oferente adquirió cualquier 
tipo de interés o derecho en una acción de la clase D. En cada caso el precio será ajustado teniendo en 
cuenta cualquier subsiguiente división accionaria, dividendo en acciones, subdivisión o reclasificación 
que afecte o esté relacionada a la clase D; o  
El ingreso neto de la Sociedad por acción de la clase D durante los cuatro últimos trimestres fiscales 
completos inmediatamente precedentes a la fecha del aviso indicado en el subinciso (i), multiplicado por 
la más alta de las siguientes relaciones: la relación precio/ingreso para ese período para las acciones de la 
clase D (si lo hubiere) o la relación precio/ingreso más alta para la Sociedad en el período de dos años 
inmediatamente precedente a la fecha del aviso indicado en el subinciso (i). Dichos múltiplos serán 
determinados en la forma común en la cual se los computa e informa en la comunidad financiera.  
Los accionistas o tenedores de títulos que los hayan sujetado a la oferta pública de adquisición podrán retirarlos de 
la misma antes de la fecha fijada para el vencimiento de dicha oferta.  
La oferta pública de adquisición no podrá ser inferior a VEINTE (20) días, ni exceder de TREINTA (30) días 
contados desde la fecha de autorización de la solicitud de oferta pública por la Comisión Nacional de Valores de 
Argentina.  
El Oferente adquirirá todas las acciones y/o títulos convertibles en acciones que antes de la fecha de la expiración 
de la oferta, sean puestos a venta de acuerdo al régimen de la oferta pública de adquisición. Si el número de dichas 
acciones o títulos es menor al mínimo al cual condicionó el Oferente la oferta pública de adquisición, el Oferente 
podrá retirarla.  
Si el Oferente no ha fijado un mínimo al cual condiciona su oferta pública de adquisición según lo indicado en el 
subinciso (i) (C) de este inciso, finalizado dicho procedimiento podrá concretar el Acuerdo Previo, si lo hubiera, 
cualquiera sea el número de acciones y/o títulos que haya adquirido bajo el régimen de la oferta pública de 
adquisición. Si hubiere fijado tal mínimo, podrá concretar el Acuerdo Previo sólo si bajo el régimen de la oferta 
pública de adquisición ha superado dicho mínimo. El acuerdo previo deberá concretarse dentro de los treinta días 
de finalizada la oferta pública de adquisición, caso contrario, para poder concretarlo será necesario repetir el 
procedimiento previsto en este Artículo.  
Si no hubiese Acuerdo Previo, el Oferente, en los supuestos y oportunidades indicados previamente en que se 
podría concretar un Acuerdo Previo, podrá adquirir libremente el número de acciones y/o títulos que informó a la

de acciones y/o títulos bajo el régimen de la oferta pública de adquisición.

efectos (en adelante, en este artículo “la Transacción Relacionada”) que comprenda a la Sociedad y cualquier otra persona 
(en adelante en este artículo “el Accionista Interesado”), que haya realizado previamente una Adquisición de control o que 
tenga para el Accionista Interesado los efectos, en cuanto a la tenencia de acciones clase D, de una Adquisición de control, 
sólo será realizada si la contraprestación que recibirá cada accionista de la Sociedad en dicha Transacción Relacionada fuera 
igual para todos los accionistas y no menor a:  

(i) 

(ii) 

El precio por acción más alto pagado por o por cuenta de dicho Accionista Interesado con relación a la adquisición 
de:  
(A) 

Acciones de la clase del tipo a ser transferidas por los accionistas en dicha Transacción Relacionada (en 
adelante, “La clase”), dentro del período de dos años inmediatamente anterior al primer anuncio público 
de la Transacción Relacionada (en adelante, “la Fecha del Anuncio”), o  
Acciones de la Clase adquiridas por dicho Accionista Interesado en cualquier Adquisición de control.  

(B) 

En ambos casos según dicho precio sea ajustado con motivo de cualquier división accionaria, dividendo en 
acciones, subdivisión o reclasificación que afecte o esté relacionada a la clase.  
El precio, cierre vendedor, más alto durante el período de treinta días inmediatamente precedente a la fecha del 
anuncio o la fecha en que el Accionista Interesado adquiera acciones de la Clase en cualquier Adquisición de 
control, de una acción de la clase según su cotización en la Bolsa de Comercio de Buenos Aires, ajustado por 
cualquier división accionaria, dividendo en acciones, subdivisión o reclasificación que afecte o esté relacionada a 
la Clase.

(iii) 

(iv) 

Un precio por acción igual al precio de mercado por acción de la Clase determinado según lo indicado en el inciso 
(ii) de esta cláusula multiplicado por la relación entre: (a) el precio por acción más alto pagado por el Accionista 
Interesado o por cuenta del mismo, por cualquier acción de la Clase, en cualquier adquisición de acciones de la 
Clase dentro de los dos años inmediatamente precedentes a la Fecha del Anuncio, y (b) dicho precio de mercado 
por acción de la Clase en el día inmediatamente precedente al primer día del período de dos años en el cual el 
Accionista Interesado adquirió cualquier tipo de interés o derecho en una acción de la Clase. En cada caso el 
precio será ajustado teniendo en cuenta cualquier subsiguiente división accionaria, dividendo en acciones, 
subdivisión o reclasificación que afecte o esté relacionada a la Clase.  
El ingreso neto de la Sociedad por acción de la Clase durante los cuatro últimos trimestres fiscales completos 
inmediatamente precedentes a la Fecha del Anuncio, multiplicado por la más alta de las siguientes relaciones: la 
relación precio/ ingreso para ese período para las acciones de la Clase (si lo hubiere) o la relación precio/ingreso 
más alta para la Sociedad en el período de dos años inmediatamente precedente a la Fecha del Anuncio. Dichos 
múltiplos serán determinados en la forma común en la cual se los computa e informa en la comunidad financiera.  

Violación de requisitos: Las acciones y títulos adquiridos en violación a lo establecido en los incisos 7 c) a 7 g), ambos 
inclusive, de este artículo, no darán derecho a voto o a cobrar dividendos u otras distribuciones que realice la Sociedad y no 
serán computadas a los fines de determinar el quórum en cualquiera de las asambleas de accionistas de la Sociedad, hasta 
tanto las acciones no sean enajenadas, en el caso de que el adquirente haya obtenido el control directo sobre YPF, o hasta 
tanto el adquirente pierda el control sobre la sociedad controlante de YPF, si la toma de control ha sido indirecta.  
Interpretación: A los efectos de este artículo 7, el término “indirectamente” incluirá a las sociedades controlantes del 
adquirente, las sociedades por él controladas o que resultarían controladas como consecuencia de la Adquisición de control, 
Oferta Pública de Adquisición, Acuerdo Previo, o Transacción Relacionada, según sea el caso, que otorgarían a su vez el 
control de la Sociedad, las sociedades sometidas a control común con el adquirente y a las demás personas que actúen 
concertadamente con el adquirente; asimismo quedarán incluidas las tenencias accionarias que una persona posea a través de 
fideicomisos, certificados de depósito de acciones (“ADR”) u otros mecanismos análogos.  

La Sociedad no se encuentra adherida al Régimen Estatutario Optativo de Oferta Pública de Adquisición Obligatoria previsto 
por el artículo 24 del Decreto 677/01.

a) 

Reglas generales: Los tenedores de acciones ordinarias o preferidas de cada clase gozarán del derecho de preferencia en la 
suscripción de las acciones de la misma clase que se emitan, en proporción a las que posean. Este derecho deberá ejercerse en 
las condiciones y dentro del plazo fijados por la Ley y reglamentaciones aplicables. Las condiciones de emisión, suscripción 
e integración de las acciones clase C podrán ser más ventajosas para sus adquirentes que las previstas para el resto de las 
acciones pero en ningún caso podrán ser más gravosas. Todo titular de un derecho de preferencia, cualquiera sea la clase de 
acción que lo origina, podrá cederlo a cualquier tercero, en cuyo caso la acción objeto de dicho derecho de preferencia se 
convertirá o consistirá en una acción clase D.  
Derecho de acrecer: El derecho de acrecer se ejercerá dentro del mismo plazo fijado para el derecho de preferencia, y 
respecto de todas las clases de acciones que no hayan sido inicialmente suscriptas. A estos efectos:

(iv) 

Las acciones clase A que no hayan sido suscriptas en ejercicio del derecho de preferencia por el Estado Nacional 
se convertirán en acciones clase D y serán ofrecidas a los accionistas de dicha Clase que hubieran manifestado la 
intención de acrecer con relación a las acciones clase A no suscriptas;  
Las acciones clase B que no hayan sido suscriptas por Provincias en ejercicio de sus derechos de preferencia 
originales, por omisión de ejercicio o por cesión del mismo, se asignarán seguidamente a las Provincias que hayan 
suscripto acciones clase B y manifestado la intención de acrecer, y el excedente se convertirá en acciones clase D 
para ser ofrecidas a los accionistas de dicha clase D que hubieran manifestado la intención de acrecer con relación 
a las acciones clase B no suscriptas;  
Las acciones clase C que no hayan sido suscriptas por personas comprendidas en el Programa de Propiedad 
Participada en ejercicio de sus derechos de preferencia originales, por omisión de ejercicio o por cesión del 
mismo, se asignarán a aquellas de las personas comprendidas en dicho régimen que hayan suscripto acciones clase 
C y manifestado la intención de acrecer, y el excedente se convertirá en acciones clase D para ser ofrecidas a los 
accionistas de dicha clase que hubieran manifestado la intención de acrecer con relación a las acciones clase C no 
suscriptas;  
Las acciones clase D que no hubieren sido suscriptas en ejercicio de derechos de preferencia emanados de 
acciones de esa clase serán asignadas a aquellos de los suscriptores de esa clase que hayan manifestado la 
intención de acrecer;

sean exigidos por la legislación societaria vigente en cada momento o sean necesarios para cumplir las disposiciones 
aplicables de las Leyes 23.696 y 24.145.

necesario que la emisión de obligaciones negociables sea decidida por la asamblea, ésta podrá delegar en el Directorio todas 
o algunas de las condiciones de emisión.  
Otros títulos: La Sociedad podrá emitir bonos de preferencia y otros títulos admitidos por la legislación aplicable. Los bonos 
de preferencia otorgarán a sus titulares el derecho de suscripción preferente en los aumentos de capital que se decidan en el 
futuro y hasta el monto que dichos bonos prevean. En la suscripción de dichos bonos y otros títulos convertibles, los 
accionistas tendrán derecho de preferencia en los términos y en los casos previstos en el artículo 8º de este Estatuto.  
Conversión a clase D: Todo título convertible emitido por la Sociedad dará derecho a conversión sólo en acciones clase D. 
Su emisión deberá ser autorizada por asamblea especial de la clase D.  

TITULO V  
DIRECCION Y ADMINISTRACION  

Artículo 11°—Directorio  
a) 

Integración: La dirección y administración de la Sociedad estará a cargo de un directorio integrado por un número de once 
(11) a veintiún (21) directores titulares, según lo determine la Asamblea, los que serán designados con mandato entre 1 y 3 
ejercicios según lo determine la Asamblea en cada caso, pudiendo ser reelegidos indefinidamente, sin perjuicio de lo 
establecido por el inciso e) de este artículo.  
Directores suplentes: Cada clase de acciones designará un número de directores suplentes igual o menor al de titulares que le 
corresponda designar. Los directores suplentes llenarán las vacantes que se produzcan dentro de su respectiva clase en el 
orden de su designación cuando tal vacante se produzca, sea por ausencia, renuncia, licencia, incapacidad, inhabilidad o 
fallecimiento, previa aceptación por el directorio de la causal de sustitución cuando ésta sea temporaria.  
Designación: Los directores serán designados por voto mayoritario dentro de cada una de las clases de acciones ordinarias, 
de la siguiente manera:  

(i) 

(ii) 

(iii) 

la clase A elegirá un director titular y un suplente mientras exista al menos una acción clase A;  
la designación del resto de los directores titulares y suplentes (que en ningún caso será menor de seis titulares y un 
número igual o menor de suplentes) corresponderá a la clase D. Las clases B y C votarán conjuntamente con las 
acciones clase D en la asamblea especial de ésta última convocada para la elección de Directores;  
en las asambleas especiales de clase D convocadas para la elección de directores se podrá votar por voto 
acumulativo con arreglo a las previsiones del artículo 263 de la Ley 19.550, incluso cuando a ella concurran 
accionistas tenedores de acciones A, B ó C conforme a lo previsto anteriormente.  

Ausencia de una clase: Si no hubiere ninguna acción de una determinada clase con derecho a elegir directores de clase, 
presente en una asamblea celebrada en segunda convocatoria y convocada para elegir directores, los directores de dicha clase 
serán elegidos por los accionistas de las restantes clases votando conjuntamente como si constituyeran una sola clase salvo en 
caso en que la ausencia de accionistas ocurriera en las asambleas de las clases A, B o C en cuyo caso el síndico designado 
por las acciones clase A o por las acciones clase A, B y C en conjunto, según corresponda con arreglo a lo previsto en el 
Artículo 21 inciso b) procederá a efectuar la designación de directores titulares y suplentes de aquella de dichas clases que 
hubieren estado ausentes.  
Elección escalonada: La elección será por el plazo que establezca la Asamblea según lo previsto en el art. 11 inc. a), salvo 
cuando se elijan directores para completar el mandato de los reemplazados.

Nominación de candidatos: En cada asamblea que deba elegir directores para la clase D, todo accionista, o grupo de 
accionistas de la clase D que posea más del tres por ciento (3%) del capital representado por acciones clase D, podrá requerir 
que se envíe a todos los accionistas de esa clase la lista de candidatos que ese accionista o grupo de accionistas propondrá a 
la asamblea de dicha clase para su elección. En el caso de bancos depositarios que tengan acciones registradas a su nombre, 
esta regla se aplicará con respecto a los beneficiarios. Igualmente, el directorio podrá proponer candidatos a directores a ser 
electos por las asambleas de las clases respectivas, cuyos nombres se comunicarán a todos los accionistas junto con las listas 
propuestas por los accionistas mencionados en primer término. Las reglas anteriores no impedirán a ningún accionista 
presente en la asamblea proponer candidatos no incluidos en las propuestas circularizadas por el directorio. No podrá 
efectuarse ninguna propuesta de elección de directores para ninguna de las clases, antes del acto de la asamblea o en el curso 
de la misma, sin presentar a la Sociedad prueba escrita de la aceptación del cargo por los candidatos propuestos.  
Forma de la elección: Sin perjuicio de lo establecido sobre voto acumulativo por el subinciso (vi) del inciso (c) de este 
Artículo la elección de directores de la clase D se efectuará por lista siempre que ningún accionista lo objete; en caso 
contrario, se efectuará individualmente. Se declarará electa a la lista o persona, según el caso, que obtenga la mayoría 
absoluta de las acciones clase D presentes en la asamblea; si ninguna lista obtuviera tal mayoría, se realizará una nueva 
votación en la que participarán las dos listas o personas más votadas, considerándose electa la lista o persona que en tal 
votación obtenga la mayor cantidad de votos.  
Remoción: Sujeto a los requisitos de quórum aplicables, cada clase, por mayoría de las acciones de la clase presente en la 
asamblea, podrá remover a los directores por ella elegidos siempre que la remoción haya sido incluida en el orden del día.  

Artículo 12°—Garantía

Class A shares of stock, only the National Government shall be the holder of class A shares of stock;  
Class B shares of stock, originally destined to be acquired by holders of Consolidation Bonds of Gas and Oil 
Royalties or creditors of the Nation on account of gas and oil royalties. Class B shares of stock acquired by a 
holder of such Bonds other than a Province or the National Government shall become Class D shares of stock;  
Class C shares of stock, originally destined by the National Government to the Corporation’s employees under the 
Shared Ownership Program set forth in Act 23,696. Class C shares of stock not purchased by the Corporation’s 
employees under the Shared Ownership Program shall become class A shares of stock; and  
Class D shares of stock, thus converted due to the transfer of class A, B or C shares of stock to any person in 
accordance with the following rules:  
Class A shares of stock transferred by the National Government to any person shall become class D shares of 
stock, except for transfers to the Provinces, if previously authorized by law, in which case they shall not change 
their class.  
Class B shares of stock that the Provinces transfer to any person other than a Province shall become class D shares 
of stock.  

Class C shares of stock that are transferred to third parties beyond the Shared Ownership Program shall become 
class D shares of stock.  
Class D shares of stock shall not change to other classes by virtue of the subscription or acquisition thereof by the 
National Government, the Provinces, other public legal entity or by the personnel participating in the Shared 
Ownership Program.  

c) 

Class A special rights: The affirmative vote of class A shares of stock, whatever the percentage of capital stock that such 
class of shares represents, shall be required so that the Corporation validly resolves to:  

(i) 

(ii) 

(iii) 

(iv) 

(v) 

Determine the merger with another or other companies;  
Accept that the Corporation, through the acquisition of its shares by third parties, shall become subject to a 
takeover, whether consented or hostile, representing the holding of more than fifty percent (50 %) of the capital 
stock of the Corporation;

Preferred shares of stock: The Corporation may issue preferred shares with or without voting right, which shall be divided 
into classes A, B, C, and D. The same rules on ownership and conversion set forth in subsection b) above for the same class 
of shares of common stock shall be applied to each class of preferred stock. When preferred shares of stock exercise their 
voting right (whether temporarily or permanently), they shall do so as members, to such effect, of the class they belong to.  
Capital Increases: The capital may be increased up to five times its original amount by resolution passed at the regular 
shareholders’ meeting, in accordance with the provisions of section 188 of Act 19,550, such limit being ruled out if the 
Corporation is authorized to make a public offering of its shares of stock. The regular shareholders’ meeting shall establish 
the nature of the shares to be issued on account of the capital increase, pursuant to the conditions set forth in these By-laws, it 
being able to delegate to the Board of Directors the power to set the time of issuance, as well as the determination of the 
payment terms and conditions of the shares, being also empowered to carry out any other delegation authorized by law. The 

e)

issuance of shares of preferred or common stock shall be carried out per classes, respecting the proportion existing among the 
different classes as of the date of issuance, without prejudice to the modifications that may subsequently be derived from the

kind of event. The information referred to above shall also include the transaction date, the price, the number of shares 
purchased and the intent of the purchaser to acquire a larger stake or to take over control of the corporate will. If the 
purchaser is made up of a group of individuals, it shall be bound to identify the members composing the group. The 
information herein provided for shall be furnished in relation to acquisitions carried out after the one informed first, when the 
limit on the amounts of class D shares indicated in the latest information shall be exceeded again in accordance with the 
provisions hereunder.  
Takeover: If the terms of subsections e) and f) of this section are not complied with, it shall be forbidden to acquire shares or 
securities of the Corporation, whether directly or indirectly, by any means or instrument (including within the meaning of the 
term “securities”, without limitation, debentures, corporate bonds and stock coupons) convertible into shares if, as a result of 
such acquisition, the purchaser becomes the holder of, or exercises the control of, class D shares of stock of the Corporation 
which, in addition to its prior holdings of such class (if any), represent, in the aggregate, FIFTEEN PERCENT (15%) or more 
of the capital stock, or TWENTY PERCENT (20%) or more of the outstanding class D shares of stock, if the shares 
representing such TWENTY PERCENT (20%) constitute, at the same time, less than FIFTEEN PERCENT (15%) of the 
capital stock.  

Notwithstanding the foregoing: (i) acquisitions by the person already holding, or the person already exercising control of, 
shares representing more than FIFTY PERCENT (50%) of the capital stock shall be excluded from the provisions of 
subsections e) and f) of this section; and (ii) any subsequent acquisitions by any person already holding, or any person 
already exercising the control of, shares representing FIFTEEN PERCENT (15%) or more of the capital stock, or TWENTY 
PERCENT (20%) or more of outstanding Class D shares, if the shares representing such TWENTY PERCENT 
(20%) constitute, at the same time, less than FIFTEEN PERCENT (15%) of the capital stock, provided the shares the 
purchaser already holds or becomes a holder of (including the shares it held prior to the acquisition and those it acquired by 
virtue thereof) do not exceed FIFTY PERCENT (50%) of the capital stock, shall be excluded from the provisions of 
subsection e) paragraph (ii) and subsection f) of this section.  

Acquisitions referred to in this subsection d) are called “Takeovers”.

A statement indicating that the takeover bid shall be open to all shareholders and holders of securities

Any additional information, including the Bidder’s accounting statements, as the Corporation may

wrong conclusions or when the information submitted is incomplete or insufficient.  

The Board of Directors shall call special meeting of class A shares of stock, by any effective means, to be held ten 
business days following the receipt by the Corporation of the notice indicated under paragraph (i), for the purpose 
of considering the approval of the takeover bid, and it shall submit to such meeting its recommendation in that 
regard. If the meeting is not held despite the call, or if it is held but the takeover bid is rejected, the latter shall not 
be carried out, nor shall the Prior Agreement, if any, be executed.  
The Corporation shall send by mail to each shareholder or holder of securities convertible into stock, at the 
Bidder’s cost and expense, and with reasonable due diligence, a copy of the notice delivered to the Corporation in 
accordance with the provisions of paragraph (i). The Bidder shall make an advance payment to Corporation of the 
funds required for such purpose.  
The Bidder shall send by mail or otherwise deliver, with reasonable due diligence, to each shareholder or holder of 
securities convertible into stock who shall so request, a copy of the notice delivered to the Corporation and shall 
publish a notice containing substantially the information stated in paragraph (i), at least once a week, starting on

(A) 

the highest price per share or security paid by the Bidder, or on behalf thereof, in relation to any 
acquisition of class D shares of stock or securities convertible into class D shares of stock within the two-
year period immediately preceding the notice of Takeover, adjusted as a consequence of any division of 
shares, stock dividend, subdivision or reclassification affecting or related to class D shares of stock; or  
The highest closing price, at the seller’s rate, during the thirty-day period immediately preceding such 
notice, of a class D share of stock as quoted by the Buenos Aires Stock Exchange, in each case as 
adjusted as a consequence of any division of shares, stock dividend, subdivision or reclassification 
affecting or related to class D shares of stock; or  
A price per share equal to the market price per class D share of stock determined as stated in paragraph 
(B) herein multiplied by the ratio between: (a) the highest price per share paid by the Bidder, or on his 
behalf, for any class D share of stock, in any share acquisition of this class within the two-year term 
immediately preceding the notice date indicated in paragraph (i), and (b) the market price for class D 
share of stock on the day immediately preceding the first day of the two-year period in which the Bidder 

(B) 

(C)

acquired any type of interest or right in a class D share of stock. In each case the price shall be adjusted 
taking into account the subsequent division of shares, stock dividend, subdivision or reclassification 
affecting or related to class D; or  

(D) 

The Corporation’s net income per class D share during the last four complete fiscal quarters immediately 
preceding the notice date indicated in paragraph (i), multiplied by the higher of the following ratios: the 
price/income ratio for that period for class D shares of stock (if any) or the highest price/income ratio for 
the Corporation during the two-year period immediately preceding the notice date indicated in paragraph 
(i). Such multiples shall be determined by applying the regular method used by the financial community 
for computing and reporting purposes.  

The shareholders or security holders that have subjected them to the takeover bid may withdraw them from the bid 
before the date established for the expiration of such bid.  
The takeover bid shall be open for a minimum term of TWENTY (20) days and a maximum term of THIRTY 
(30) days as from the date the bid was authorized by Comisión Nacional de Valores de Argentina (Argentine 
Securities Exchange Commission).  
The Bidder shall acquire all shares and/or securities convertible into stock that before the expiration date of the 
takeover bid are set on sale in accordance with the regime ruling takeover bids. If the number of such shares or 
securities is lower than the minimum number to which the Bidder conditioned the takeover bid, the Bidder may 
withdraw it.  
If the Bidder has not set a minimum number as a condition to the takeover bid as stated in paragraph (i) (C) of this 
subsection, once this procedure has finished, the Bidder may execute the Prior Agreement, if any, whatever the 
number of shares of stock and/or securities purchased thereby under the regime regulating takeover bids. If he has 
set that minimum number, the Bidder shall execute the Prior Agreement only if the minimum number required 
under the regime ruling takeover bids has been exceeded. The prior agreement shall be executed within thirty days 
as from the closing of the takeover bid, otherwise, it shall be necessary to repeat the procedure provided for in this 
section to execute it.  

(vi) 

(vii) 

(vii) 

(ix) 

g) 

If there existed no Prior Agreement, the Bidder, in the afore-mentioned cases and opportunities where such Prior 
Agreement could be executed, may purchase freely the number of shares of stock and/or securities that he reported 
to the Corporation through the communication set forth in paragraph (i) of this subsection, provided the Bidder has 
not purchased such number of shares of stock and/or securities under the takeover bid regime.  
Related transactions: Any merger, consolidation or any other combination leading to substantially the same effects 
(hereinafter called “the Related Transaction”) comprising the Corporation or any other person (hereinafter “the Interested 
Shareholder”) that has previously carried out a Takeover, or having for the Interested Shareholder the effects, regarding the 
holding of class D shares of stock, of a Takeover, shall only be performed if the consideration to be received by each 
shareholder from the Corporation in such Related Transaction is equal for all shareholders and not lower than:  

(i) 

(ii) 

(iii) 

The highest price per share of stock paid by or on account of such Interested Shareholder in relation to the 
acquisition of:  
(A) 

Shares of the class to be transferred by the shareholders in such Related Transaction (hereinafter called 
“the Class”), within the two-year period immediately preceding the first public announcement of the 
Related Transaction (hereinafter called “the Announcement Date”), or  
Shares of the Class purchased by said Interested Shareholder in any Takeover.  

(B) 

In both cases as adjusted by virtue of any stock division, share dividend, subdivision or reclassification affecting 
or related to the class.  
The highest closing price, at the seller’s rate, during the thirty-day period immediately preceding the 
announcement date or the date of purchase of the shares of the Class by the Interested Shareholder in any 
Takeover, of a share of the Class as quoted at the Buenos Aires Stock Exchange, adjusted by any division of 
shares, stock dividend, subdivision or reclassification affecting or related to the Class.  
A price per share equal to the market price of a share of the Class determined as established in subsection (ii) of 
this section multiplied by the ratio between: (a) the highest price per share paid by the Interested Shareholder or on 
his behalf, for any share of the Class, in any acquisition of shares of the Class within the two-year period 
immediately preceding the Announcement Date, and (b) the market price per share of the Class on the day 
immediately preceding the first day of the two-year period in which the Interested Shareholder acquired any type 
of interest or right in a share of the Class. In each case the price shall be adjusted taking into account the 
subsequent division of shares, stock dividend, subdivision or reclassification affecting or related to the Class.  

5 

 
  
   
      
(iv) 

The net income of the Corporation per each share of the Class during the last four complete fiscal quarters 
immediately preceding the Announcement Date, multiplied by the higher of the following ratios: the price / 
income ratio for that period for the shares of stock of the Class (if any) or the highest price / income for the 
Corporation in the two-year period immediately preceding the Announcement Date. Such multiples shall be 
determined using the regular method used by the financial community for their computation and reporting.  

h) 

i) 

Breach of Requirements: Shares of stock and securities acquired in breach of the provisions of subsections 7 c) through 7 g), 
both included, of this section, shall not grant any right to vote or collect dividends or other distributions that the Corporation 
may carry out, nor shall they be computed to determine the presence of the quorum at any of the shareholders’ meetings of 
the Corporation, until such shares of stock are sold, in the case the purchaser has obtained the direct control of YPF, or until 
the purchaser loses the control of the YPF’s parent company, if the takeover has been indirect.  
Construction: For the purposes of section 7, the term “indirectly” shall include the purchaser’s parent companies, the 
companies controlled by it or that would end up under the control thereof as a consequence of the Takeover, Takeover Bid, 
Prior Agreement, or Related Transaction, as the case may be, that would grant at the same time the control of the 
Corporation, the companies submitted to the common control of the purchaser and other persons acting jointly with the 
purchaser; likewise, the holdings a person has through trusts, American Depositary Receipts (“ADR”) or other similar 
mechanisms shall be included.  

The Corporation is not adhered to the Optional Statutory Regime for the Mandatory Acquisition of Shares in a Takeover Bid 
(Régimen Estatutario Optativo de Oferta Pública de Adquisición Obligatoria) under the regulations of section 24 of Decree 
677/01.  

Section 8 – Preemptive right  
a) 

General rules: The holders of each class of common or preferred stock shall be entitled to a preemptive right in the 
subscription of the shares of stock of the same class to be issued, pro rata their holdings. This right shall be exercised under 
the conditions and terms established in the applicable Law and regulations. The conditions of issuance, subscription and 
payment of class C shares of stock may be more advantageous for their purchasers than the ones provided for the rest of the 
shares; however, under no circumstances shall they be more onerous. Any preemptive right holder, whatever the class of 
stock originating it, may assign it to any third party, in which case the share of stock entitled to such preemptive right shall 
become or consist of a class D share of stock.  
Accretion Right: The accretion right shall be exercised within the same period fixed for the preemptive right, and with 
respect to all classes of shares that have not been initially subscribed. To such purposes:  

b) 

(i) 

(ii) 

(iii) 

(iv) 

(v) 

Class A shares that have not been subscribed in exercise of the preemptive right of by the National Government 
shall be converted into class D shares and shall be offered to the shareholders of such Class that have expressed 
their intention to exercise their accretion right with respect to non-subscribed class A shares;  
Class B shares that have not been subscribed by the Provinces in exercise of their original preemptive rights, for 
failure to exercise such right or due to the assignment thereof, shall be allocated to the Provinces having 
subscribed class B shares and having expressed their intention to exercise their accretion right, and the balance 
shall be converted into class D shares to be offered to class D shareholders who have expressed their intention to 
exercise their accretion right with respect to non-subscribed class B shares;  
Class C shares that have been subscribed by the persons comprised in the Shared Ownership Program in exercise 
of their original preemptive rights, due to failure to do so or to assignment thereof, shall be assigned to those 
persons comprised in such regime that have subscribed class C shares and have stated their intention to exercise 
their accretion right, and the balance shall be converted into class D shares to be offered to shareholders of that 
class who have stated their intention to exercise their accretion right with respect to non-subscribed class C shares;  
Class D shares not subscribed in exercise of the preemptive rights incidental to that class of shares shall be 
assigned to the subscribers of that class who have stated their intention to exercise their accretion right;  
The remaining class D shares shall be assigned to shareholders of other classes who have stated their intention to 
exercise their accretion right.  

c) 

Limits: The preemptive and accretion rights set forth in the preceding paragraphs shall only exist provided they are required 
by the corporate legislation in force at the time or that they are necessary to comply with the applicable provisions of Acts 
23,696 and 24,145.

conditions to the Board of Directors.  
Other securities: The Corporation may issue preferential right securities (“bonos de preferencia”) and other securities

such securities and other convertible securities, the shareholders shall have the preemptive right under the terms and in the 
cases established in section 8 of these By-laws.

ADMINISTRATION AND MANAGEMENT  
Section 11 – Board of Directors  
a) 

Number: The administration and management of the Corporation shall be in the hands of a Board of Directors composed of 
at least eleven (11) and not more than twenty-one (21) regular Directors, as may be decided at the Shareholders’ Meeting, 
who shall be appointed to serve for a term of 1 to 3 fiscal years, as may be decided at the Shareholders Meeting in each case, 
and may be reelected indefinitely, notwithstanding the provisions of subsection e) of this section.  
Alternate directors: Each class of shares shall appoint an equal or lower number of alternate directors than the number of 
regular directors it is authorized to appoint. Alternate directors shall fill the vacancies within their respective class in the 
order of their appointment upon the occurrence of such vacancy, whether by absence, resignation, license, incapacity, 
disability or death, prior acceptance by the Board of the grounds for substitution, should it be temporary.  
Appointment: Directors shall be appointed by the majority vote within each of the classes of ordinary shares of stock, as 
indicated below:  

(i) 
(ii) 

(iii) 

class A shall appoint a regular and an alternate director provided there exists at least one class A share;  
The appointment of the other regular and alternate directors (which shall in no case be lower than six regular 
directors and an equal or lower number of alternate directors) shall correspond to class D. Classes B and C shall 
cast their votes together with class D shares at the special meeting of shareholders of such class called for the 
appointment of Directors;  
at Class D special meetings of shareholders called for the appointment of directors, directors may be elected by 
cumulative voting in compliance with provisions of section 263 of Act 19,550, even when such meeting is 
attended by holders of shares A, B or C as afore-mentioned.  

Absence of a class: If no shares of a given class entitled to vote in the election of directors of a class of shares are present at a 
meeting held on second call for the appointment of directors, then the directors of such class shall be elected by the 
shareholders of the remaining classes voting jointly as if they belonged to a single class, except when the absence of 
shareholders shall occur at meetings of Class A, B or C shareholders, in which case the statutory auditor elected by class A 
shares or jointly by classes A, B and C, as appropriate pursuant to the provisions of section 21, subsection b), shall appoint 
the regular and alternate directors of those classes that are absent.  
Staggered Appointment: Directors shall be appointed for the term decided at the meeting as provided for in section 11, 
subsection a), except when directors are appointed to complete the term of office of the directors being replaced.  
Candidate nomination: Each meeting at which directors for class D shares are to be elected, any class D shareholder or group 
of shareholders holding more than three per cent (3%) of the capital represented by class D shares, may request that all 
shareholders of such class be sent a list of the candidates to be proposed by such shareholder or group of shareholders at the 
meeting of such class for the election thereof. In the case of depositary banks having shares registered in their name, these 
provisions shall apply with respect to the beneficiaries. Likewise, the board of directors may propose candidates for the office 
of directors to be elected at the shareholders’ meetings of the respective classes, whose names shall be notified to all 
shareholders together with the lists proposed by the shareholders first above-mentioned. The preceding provisions shall not 
prevent any shareholder present at the meeting from proposing candidates not included in the nominations notified by the 
Board. No proposal for the election of directors for any of the classes may be made, prior to the meeting or during the course 
thereof, unless the written acceptance of the offices by the nominated candidates is presented to the Corporation.

g) 

h) 

Manner of election: Notwithstanding the provisions related to cumulative voting set forth in paragraph (vi), subsection c) of 
this Section, class D Directors shall be elected by voting a whole list provided no shareholder shall object thereto; otherwise, 
it shall be carried out individually. The list or person, as the case may be, shall be considered elected when it has obtained the 
absolute majority vote of class D shares of stock present at the meeting. Should no list obtain a majority vote, a new voting 
shall take place in which the two lists or persons receiving the higher number of votes shall participate, and the list or person 
obtaining the higher number of votes shall be deemed elected.  
Removal: Subject to the requirements of applicable quorums, each class, by a majority vote of the shares of the class present 
at the meeting, may remove the directors elected thereby, provided the removal has been included in the agenda.  

Section 12 – Performance Bond  
Each Regular Director shall furnish a bond for the amount of at least ten thousand Pesos ($ 10,000) or its equivalent, which may 
consist of securities, sovereign bonds or amounts of money in domestic or foreign currencies deposited with financial institutions or 
securities clearing houses, to the order of the Corporation, or sureties or bank guaranties, or surety bonds or third party insurance to 
the name of the Corporation, which cost shall be borne by each Director; no bond shall be furnished by depositing funds in the 
corporate safe deposit box. When the bond is furnished by depositing securities, sovereign bonds or sums of money in domestic or 
foreign currencies, the conditions under which such deposits are made shall ensure their unavailability during the course of any 
liability claims against him. Alternate Directors shall only furnish the mentioned bond in the event of taking office in replacement of a

Hydrocarbon liquid volumes represent crude oil, condensate, gasoline and NGL estimated to be recovered during field 

separation and plant processing and are reported in thousands of stock tank cubic meters. Natural gas volumes represent expected gas 
sales, and are reported in millions of cubic meters (at standard conditions of 15 degrees Celsius and 1 atmosphere). The volumes have 
not been reduced for fuel usage in the field. Based on the interpretation that Argentine royalties are a financial obligation or 
substantially equivalent to a production or similar tax, royalties payable to the provinces have not been deducted from the reported 
volumes.  

Proved gas volumes are based on firm and existing gas contracts and on the reasonable expectation that such gas sales contracts 

will be renewed on similar terms in the future.  

The Technical Explanations which explain the field work carried out by GCA and general methodology is attached in 

Appendix II.  

This audit examination was based on reserve estimates and other information provided by YPF to GCA through September 30, 
2009 and included such tests, procedures and adjustments as were considered necessary. All questions that arose during the course of 
the certification process were resolved to our satisfaction. GCA believes that the assumptions, data, methods and procedures used in 
connection with the preparation of this report are appropriate for the purpose served by the report.  

The commerciality and economic tests for the September 30, 2009 Reserve volumes were based on realized crude oil, 

condensate, NGL and average gas sales prices as shown in the following table, as advised by YPF.

Future capital costs were derived from development program forecasts prepared by YPF for the field. Recent historical 

operating expense data were utilized as the basis for operating cost projections.  

It is GCA’s opinion that the estimates of total remaining recoverable hydrocarbon liquid and gas volumes as of September 30, 
2009, are, in the aggregate, reasonable and have been prepared in accordance with the definitions for Proved reserves set out in Rule 
4-10 of Regulation S-X of the United States Securities and Exchange Commission, attached in Appendix III.  

This assessment has been conducted within the context of GCA’s understanding of YPF’s petroleum property rights as 
represented by YPF’s management as well as the effects of petroleum legislation, taxation and other regulations that currently pertain 
to the property. GCA is not aware of any potential regulation amendments which could affect the ability to recover the estimated 
reserves. GCA is not in a position to attest to property title, financial interest relationships or encumbrances thereon for any part of the 
appraised properties or interests.

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 reserve engineering and resource assessment 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 reserves or resources prepared by other parties may differ, perhaps materially, from those contained within 
this report. The accuracy of any Reserve or Resource 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, Reserve and Resource 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.  

For this assignment, GCA served as independent Reserve auditors. The firm’s officers and employees have no direct or indirect 

interest holdings in the property units evaluated. GCA’s remuneration was not in any way contingent on reported reserve estimates.  

Finally, please note that GCA reserves the right to approve, in advance, the use and context of the use of any results, statements 

or opinions expressed in this report. Such approval shall include, but not be confined to, statements or references in documents of a

TECHNICAL DESCRIPTION OF THE AUDIT REVIEW  

All of the proved reserve statements made by YPF were audited using the information supplied by the client in the form of 
production databases or spreadsheets on which decline analysis could be used whenever applicable. In those cases where a secondary 
recovery process takes place, a WOR or Oil Cut projection was made to an economic limit to assess the potential reserves to recover 
by those means or in the case of a gas field, a material balance was analyzed using updated static pressure data. What follows is a brief 
introduction on the properties location, concession participation and end of concession dates.  

Acambuco area is comprised of two major gas fields, Macueta and San Pedrito in the Noroeste basin. They are operated by Pan 

American under the UTE Acambuco concession through February 16, 2040 and October 26, 2036 respectively where YPF owns a 
22.5% WI. Royalties paid to the Salta province are 12%.  

Aguada Pichana is a major gas field located in the Neuquina basin that consists of a main production unit and the Aguada 

Pichana Norte block that is being developed. They are operated by Total under the same concession that extends through 
November 14, 2027. YPF owns a 27.27% W.I. and royalties paid to the province of Neuquén are 15%.

analyzed are San Sebastián a major gas field followed by Cañadón Piedras, Cabo Nombre, La Sara, Sección Baños while Los 
Chorrillos (this concession ends April 10, 2016) and Cabeza de León are oil fields with varying amount of solution gas.  

What follows is an explanation of those cases where a discrepancy between YPF and GCA exceeds the tolerance limit required 

by RY and the reasons for those differences.  

Discrepancies Explained  
Acambuco  
1. 
Acambuco block consists of two gas fields, Macueta and San Pedrito. In Macueta the proved developed producing reserves were 

evaluated by YPF using a dynamic model that ties a material balance to nodal analysis. They were verified by GCA using decline 
analysis as the field is at a depletion stage; they seemed reasonable and were accepted. The operator is committed to drill one new well 
(Mac-1006) to the Huamampampa formation, adding compression capacity to the existing facilities to bring PUD reserves on line in 
2011. This block is connected with San Alberto in Bolivia, one of the largest gas fields operating in Bolivia. To model the output from 
the new well and also the impact of compression, YPF used the integrated nodal analysis model assuming that the whole San Alberto 
field is represented by one well. Some concerns expressed by GCA on YPF analysis are as follows.  

a. 

b. 

c. 

d. 

e. 

f. 

It is of public knowledge that on this basin there is always a risk water production associated to the natural fractures which 
is evidenced by the pressure build-up analysis provided by YPF on Mac-1003 as of 3-5 Mar/2008 where a qualified 
interpretation shows an increase of the well skin damage attributed to a water bank.  
However the model included a small aquifer pot, doubts still remain about its behavior in the long range from the 
interaction of both San Alberto and Macueta fields.  
There is also a risk of raising the gas-water contact as the suction pressure is reduced by a much larger reservoir volume 
across the border.  
According to the data provided by YPF there is a long pipeline (about 55 km) with pronounced changes in the pipeline 
layout progressive. However the current LG Ratio is low, there is a risk of producing more water under compression and 
also to have liquid holdups at both the well and the pipeline.  
Another concern is that according to YPF estimates, drilling one well on each field would be almost duplicating the 
proved producing reserves.  
In order to acknowledge an increasing water/gas ratio the Proved Undeveloped volumes were reduced by 40%. Similar 
considerations were given to San Pedrito field attending similar production histories, facilities conditions and same 
reservoirs.  

2.   Aguaragüe  

Aguaragüe proved reserves evaluation was done applying decline analysis by field. There is a good agreement on proved 
reserves for most of the fields except for Aguaragüe Santa Rosa Icla where the decline proposed by the client was significantly 
changed to honor latest production data showing a steep change in the decline rate from 18 to 31 %/year.  

3.   Palmar Largo  

Palmar Largo shows on a long range a steady decline of 14 %/yr. However that on a shorter span there is a cyclic drop of 
45%/yr attributed to a continuous process of well damage by scales that plug perforations and they need to be cleaned to restore 
production.  

The sustainment of the field production is achieved by jobs that in general do not open new zones. Being maintenance jobs like 

pullings, etc they should be considered part of the operating expenses and the decline analysis should reflect that fact.

Reserves Definitions  
(SEC)  

 
 
SEC DEFINITIONS FOR OIL AND GAS RESERVES  

Proved Oil and Gas Reserves  

Proved oil and gas reserves are the estimated quantities of crude oil, natural gas and natural gas liquids which geological and 

engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing 
economic and operating conditions, i.e., prices and costs as of the date the estimate is made. Prices include consideration of changes in 
existing prices provided only by contractual arrangements, but not on escalations based upon future conditions.  
(i)  Reservoirs are considered proved if economic producibility is supported by either actual production or conclusive formation 

tests. The area of a reservoir considered proved includes (A) that portion delineated by drilling and defined by gas-oil and/or oil-
water contacts, if any; and (B) the immediately adjoining portions not yet drilled, but which can be reasonably judged as 
economically productive on the basis of available geological and engineering data. In the absence of information on fluid 
contacts, the lowest known structural occurrence of hydrocarbons controls the lower proved limit of the reservoir.  

(ii)  Reserves which can be produced economically through application of improved recovery techniques (such as fluid injection) are 
included in the “proved” classification when successful testing by a pilot project, or the operation of an installed program in the 
reservoir, provides support for the engineering analysis on which the project or program was based.  

(iii)  Estimates of proved reserves do not include the following: (A) oil that may become available from know reservoirs, but is 

classified separately as “indicated additional reserves”; (B) crude oil, natural gas and natural gas liquids, the recovery of which 
is subject to reasonable doubt because of uncertainty as to geology, reservoir characteristics, or economic factors: (C) crude oil, 
natural gas, and natural gas liquids that may occur in undrilled prospects; and (D) crude oil, natural gas and natural gas liquids 
that may be recovered from oil shales, coal, gilsonite and other such sources.  

Proved Developed Oil and Gas Reserves  

Proved developed oil and gas reserves that can be expected to be recovered through existing wells with existing equipment and 

operating methods. Additional oil and gas expected to be obtained through the application of fluid injection or other improved 
recovery techniques for supplementing the natural forces and mechanisms of primary recovery should be included as “proved 
developed reserves” only after testing by a pilot project or after the operation of an installed program has confirmed through 
production response that increased recovery will be achieved.  

PROVED UNDEVELOPED RESERVES  

Proved undeveloped oil and gas reserves are reserves 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. Reserves or undrilled acreage shall be limited to 
those drilling units offsetting productive units that are reasonably certain of production when drilled. Proved reserves for other 
undrilled units can be claimed only where it can be demonstrated with certainty that there is continuity of production from the existing 
productive formation. Under no circumstances should estimates for proved 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 tests in the area and in the same reservoir.
