MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of PETRÓLEO BRASILEIRO S.A. - PETROBRAS and subsidiaries (‘the Company”) is responsible for establishing and maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting.

The Company’s internal control over financial reporting is a process designed by, or under the supervision of, the Company’s Audit Committee, Chief Executive Officer, Chief Financial Officer 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 consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States. The 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 consolidated financial statements in accordance with accounting principles generally accepted in the United States, 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 consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements on a timely basis. Therefore even those systems determined to be effective can provide only reasonable assurance with respect to consolidated financial statements preparation and presentation. 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.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006, based on the criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations – COSO – of the Treadway Commission. Based on that assessment, management has concluded that as of December 31, 2006 the Company’s internal control over financial reporting is effective.

Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006 has been audited by KPMG Auditores Independentes, the Company’s independent registered public accounting firm, which opinion is stated in their report, dated April 5, 2007, included herein.

The Executive Board and Shareholder of
Petróleo Brasileiro S.A. - Petrobras

We have audited the accompanying consolidated balance sheet of Petróleo Brasileiro S.A. – Petrobras (and subsidiaries) as of December 31, 2006, and the related consolidated statements of income, shareholders' equity and comprehensive income, and cash flows for the year then ended. We also have audited management's assessment, included in the accompanying Management's Report on the Internal Control over Financial Reporting, that Petróleo Brasileiro S.A. - Petrobras (and subsidiaries) maintained effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Petróleo Brasileiro S.A. – Petrobras' management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financ ial r eport ing. Our responsibility is to express an opinion on these consolidated financial statements, an opinion on management's assessment, and an opinion on the effectiveness of the Company's internal control over financial reporting based on our audits. The accompanying consolidated balance sheet of Petróleo Brasileiro S.A. – Petrobras as of December 31, 2005 and the related consolidated statements of income, shareholders' equity and cash flows for each of the years ended December 31, 2005 and 2004, were audited by other auditors whose report thereon dated February 17, 2006, expressed a unqualified opinion on those statements.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audit of financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Petróleo Brasileiro S.A. - Petrobras as of December 31, 2006, and the results of its operations and its cash flows for the year then ended, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, management's assessment that Petróleo Brasileiro S.A. - Petrobras maintained effective internal control over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Furthermore, in our opinion, Petróleo Brasileiro S.A. – Petrobras maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

As discussed in the Note 2(k) to the consolidated financial statements, the Company adopted the recognition and disclosure provisions of Statement of Financial Accounting Standards No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, as of December 31, 2006.

PETRÓLEO BRASILEIRO S.A. - PETROBRAS
AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 
Expressed in Millions of United States Dollars 
(except when specifically indicated)
 

1. The Company and its Operations

PETRÓLEO BRASILEIRO S.A. - PETROBRAS is Brazil’s national oil company and, directly or through its subsidiaries (collectively, "Petrobras" or the "Company"), is engaged in the exploration, exploitation and production of oil from reservoir wells, shale and other rocks, and in the refining, processing, trade and transport of oil and oil products, natural gas and other fluid hydrocarbons, in addition to other energy related activities. Additionally, Petrobras may promote the research, development, production, transport, distribution and marketing of all sectors of energy, as well as other related or similar activities.

Petrobras was incorporated under Law No. 2,004 on October 3, 1953. Until November of 1995, Petrobras was the exclusive agent of the Brazilian Federal Government (the "Federal Government") for purposes of exploiting the Federal Government’s constitutional and statutory control over activities involving exploration, production, refining, distribution, import, export, marketing and transportation of hydrocarbons and oil products in Brazil and its continental waters. When adopted in 1953, the relevant provisions of the Brazilian constitution and statutory law gave the Federal Government a monopoly in these areas subject only to the right of companies then engaged in oil refining and the distribution of oil and oil products to continue those activities in Brazil. Therefore, except for limited competition from those companies in their grandfathered activities, Petrobras had a monopoly over its businesses for approximately 42 years. As a result of a change in the Brazilian constitution in November of 1995, and the subsequent and ongoing implementation of that change, Petrobras has ceased to be the Federal Government’s exclusive agent in Brazil’s hydrocarbons sector and up to 2001 had been operating in an environment of gradual deregulation and increasing competition.

In accordance with Law No. 9,478 ("Petroleum Law") and Law No. 9,990, dated August 6, 1997 and July 21, 2000, respectively, the fuel market in Brazil was totally liberalized beginning January 1, 2002 permitting other companies to produce and sell on the domestic market, and also to import and export oil products.

The Company also has oil and gas operations in international locations, with the most significant international operations being in other Latin American countries.

2. Summary of Significant Accounting Policies

In preparing these consolidated financial statements, the Company has followed accounting policies that are in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The preparation of these financial statements requires the use of estimates and assumptions that affect the assets, liabilities, revenues and expenses reported in the financial statements, as well as amounts included in the notes thereto.

Estimates adopted by management include: oil and gas reserves, pension and health care liabilities, environmental obligations, depreciation, depletion and amortization, abandonment costs, contingencies and income taxes. While the Company uses its best estimates and judgments, actual results could differ from those estimates as future confirming events occur.

Certain prior years amounts have been reclassified to conform to current year presentation standards. These reclassifications had no impact on the Company's net income

(a) Basis of financial statements preparation

The accompanying consolidated financial statements of PETRÓLEO BRASILEIRO S.A. - PETROBRAS (the Company) have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and the rules and regulations of the Securities and Exchange Commission (SEC). U.S. GAAP differs in certain respects from Brazilian accounting practice as applied by Petrobras in its statutory financial statements prepared in accordance with Brazilian Corporate Law and regulations promulgated by the Brazilian Securities and Exchange Commission (CVM).

2. Summary of Significant Accounting Policies (Continued)

(a) Basis of financial statements preparation (Continued)

The U.S. dollar amounts for the years presented have been translated from the Brazilian Real amounts in accordance with Statement of Financial Accounting Standards SFAS No. 52 - Foreign Currency Translation ("SFAS 52") as applicable to entities operating in non-hyperinflationary economies. Transactions occurring in foreign currencies are first remeasured to the Brazilian Real and then translated to the U.S. dollar, with remeasurement gains and losses being recognized in the statements of income. While Petrobras has selected the U.S. Dollar as its reporting currency, the functional currency of Petrobras and all Brazilian subsidiaries is the Brazilian Real. The functional currency of PIFCo and certain of the special purpose companies is the U.S. dollar, and the functional currency of Petrobras Energia Participaciones S.A. - PEPSA is the Argentine Peso.

The Company has translated all assets and liabilities into U.S. dollars at the current exchange rate (R$2.138 and R$2.3407 to US$1.00 at December 31, 2006 and 2005, respectively), and all accounts in the statements of income and cash flows (including amounts relative to local currency indexation and exchange variances on assets and liabilities denominated in foreign currency) at the average rates prevailing during the year. The net translation gain in the amount of US$3,230 in 2006 (2005 - US$3,107 and 2004 - US$1,911) resulting from this remeasurement process was excluded from income and presented as a cumulative translation adjustment ("CTA") within Accumulated Other Comprehensive Income in the consolidated statements of changes in shareholders’ equity.

(b) Basis of consolidation

The consolidated financial statements include the accounts of the Company and all majority-owned subsidiaries in which (a) the Company directly or indirectly has either a majority of the equity of the subsidiary or otherwise has management control, or (b) the Company has determined itself to be the primary beneficiary of a variable interest entity in accordance with FIN 46(R).

The marketable securities classified as trading are short term in nature as the investments are expected to be liquidated, sold, or used for current cash requirements. The marketable securities classified as available-for-sale are long term in nature as the investments are not expected to be sold or otherwise liquidated in the next twelve months. Debt securities that management has the intent and the ability to hold to maturity are classified as held-to-maturity.

The Company uses the equity method of accounting for all long-term investments for which it owns between 20% and 50% of the investee’s outstanding voting stock or has the ability to exercise significant influence over operating and financial policies of the investee. The equity method requires periodic adjustments to the investment account to recognize the Company’s proportionate share in the investee’s results, reduced by receipt of investee’s dividends.

16


Table of Contents

2. Summary of Significant Accounting Policies (Continued)

(h) Property, plant and equipment

The costs incurred in connection with the exploration, development and production of oil and gas are recorded in accordance with the “successful efforts” method. This method requires that costs the Company incurs in connection with the drilling of developmental wells and facilities in proved reserve production areas and successful exploratory wells be capitalized. In addition, costs the Company incurs in connection with geological and geophysical activities are charged to the statements of income in the year incurred, and the costs relating to exploratory dry wells on unproven reserve properties are charged to the statements of income when determined as dry or uneconomical.

The capitalized costs are depreciated based on the unit-of-production method using proved developed reserves. These reserves are estimated by the Company’s geologists and petroleum engineers in accordance with SEC standards and are reviewed annually, or more frequently when there are indications of significant changes in the Company’s reserves.

Costs of acquiring developed or undeveloped leaseholds including lease bonus, brokerage, and other fees are capitalized. The costs of undeveloped properties that become productive are transferred to a producing property account.

Exploratory wells that find oil and gas in an area requiring a major capital expenditure before production begins are evaluated annually to assure that commercial quantities of reserves have been found or that additional exploration work is underway or planned. Exploratory costs related to areas where commercial quantities have been found are capitalized, and exploratory costs where additional work is underway or planned continue to be capitalized pending final evaluation. Exploratory well costs not meeting either of these tests are charged to expense. All other exploratory costs (including geological and geophysical costs) are expensed as incurred. Exploratory dry holes are expensed.

17


Table of Contents

2. Summary of Significant Accounting Policies (Continued)

(h) Property, plant and equipment (Continued)

Costs of development wells including dry holes, platforms, well equipment and attendant production facilities are capitalized.

Costs incurred with producing wells are recorded as inventories and are expensed when the products are sold.

The Company makes its annual reviews and revision of its estimated costs associated with well abandonment and the demobilization of oil and gas production areas, considering new information about date of expected abandonment and revised cost estimates to abandon. The changes in estimated asset retirement obligation are principally related to the commercial declaration of new fields, certain changes in cost estimates, and revisions to abandonment information provided for non-operated joint ventures.

Depreciation, depletion and amortization of leasehold costs of producing properties are recorded using the unit-of-production method applied on a field by field basis as a ratio of proved developed reserves. Production platform under capital lease are depreciated on a straight-line basis over the estimated useful lives of the platforms. Depreciation, depletion and amortization of all other capitalized costs (both tangible and intangible) of proved oil and gas producing properties is recorded using the unit-of-production method applied on a field by field basis as a ratio of proved developed reserves produced. The straight-line method is used for assets with a useful life shorted than the life of the field.

2. Summary of Significant Accounting Policies (Continued)

(h) Property, plant and equipment (Continued)

Other plant and equipment are depreciated on a straight-line basis over the following estimated useful lives:

Building and improvements    25-40 years 
Equipment and other assets    3-30 years 
Platforms (1)   15-25 years 
Pipelines    30 years 

(1) In 2006 the Company reviewed prospectively the estimation of depreciation and changed the rate from 10-25 to years to 15-25 years and the effect in the result was US$67.

In accordance with SFAS No. 144 - Impairment of Long-Lived Assets (“SFAS 144”), management reviews long-lived assets, primarily property, plant and equipment to be used in the business and capitalized costs relating to oil and gas producing activities, whenever events or changes in circumstances indicate that the carrying value of an asset or group of assets may not be recoverable on the bases of undiscounted future cash flows. The reviews are carried out at the lowest level of assets to which the Company is able to attribute identifiable future cash flows. The net book value of the underlying assets is adjusted to their fair value using a discounted future cash flows model, if the sum of the expected undiscounted future cash flows is less than the book value.

The actual costs of major maintenance, including turnarounds at refineries and vessels, as well as other expenditures for maintenance and repairs, are expensed as incurred.

2. Summary of Significant Accounting Policies (Continued)

(h) Property, plant and equipment (Continued)

Interest is capitalized in accordance with SFAS No. 34 - Capitalization of Interest Cost (“SFAS 34”). Interest is capitalized on specific projects when a construction process involves considerable time and involves major capital expenditures. Capitalized interest is allocated to property, plant and equipment and amortized over the estimated useful lives or unit-of-production method of the related assets. Interest is capitalized at the Company’s weighted average cost of borrowings.

(i) Revenues, costs and expenses

Revenues from sales of crude oil and oil products, petrochemical products and others are recognized on an accrual basis when the title is transferred to the customer. Revenues from sales of natural gas are accounted for when the natural gas is transferred to the customer. Subsequent adjustments to revenues based on production sharing agreements or volumetric delivery differences are not significant. Costs and expenses are accounted for on an accrual basis.

(j) Income taxes

The Company accounts for income taxes in accordance with SFAS No. 109 - Accounting for Income Taxes ("SFAS 109"), which requires an asset and liability approach to recording current and deferred taxes. The effects of differences between the tax bases of assets and liabilities and the amounts recognized in the financial statements have been treated as temporary differences for the purpose of recording deferred income taxes.

The Company records the tax benefit of all net operating losses as a deferred tax asset and recognizes a valuation allowance for any part of this benefit which management believes will not be recovered against future taxable income using a "more likely than not" criterion.

(k) Employees’ post-retirement benefits

The Company sponsors a contributory defined-benefit pension plan covering substantially all of its employees, which is accounted for by the Company in accordance with SFAS No. 87 - Employers’ Accounting for Pensions ("SFAS 87") and SFAS 158 - “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans — an Amendment of FASB Statements No. 87, 88, 106 and 132(R)” (“SFAS 158”). Disclosures related to the plan are according to FASB Statement No. 132-R, “Employers’ Disclosures about Pensions and Other Post-retirement Benefits” (“SFAS No. 132-R”) (see Note 2 (r)).

In addition, the Company provides certain health care benefits for retired employees and their dependents. The cost of such benefits is recognized in accordance with SFAS No. 106 - Post-retirement Benefits Other Than Pensions ("SFAS 106") and “SFAS 158”.

The Company also contributes to the Brazilian pension and government sponsored pensions of international subsidiaries, social security and redundancy plans at rates based on payroll, and such contributions are expensed as incurred. Further indemnities may be payable upon involuntary severance of employees but, based on current operating plans, management does not believe that any amounts payable under this plan will be significant.

(l) Environmental and remediation costs

Environmental and remediation costs relating to current operations are expensed or capitalized, as appropriate, depending on whether such costs are expected to provide future economic benefits. Liabilities are recognized when the costs are considered probable and can be reasonably estimated.

(m) Compensated absences

The liability for future compensation of employees for vacations is accrued as earned.

(n) Earnings per share

Earnings per share are computed using the two-class method, which is an earnings allocation formula that determines earnings per share for both preferred shares, which are participating securities and common shares. The preferred shares participate in dividends and undistributed earnings with the common shares at a predetermined formula. Such formula allocates the net income, as if all of the net income for each year had been distributed, first to the preferred shares in an amount equal to the preferred shares’ priority minimum annual dividend of the higher of 3% of their shareholders equity or 5% of their paid-in capital as stated in the statutory accounting records, then to common shares in an amount equal to the preferred shares’ priority dividend on a per share basis and any remaining net income is allocated equally to the common and preferred shares. As a result of a 2005 stock split, each American Depositary Share (ADS) for common shares represents four shares of the Company’s common shares or four shares of the Company’s preferred shares.

(o) Research and development costs

Research and development costs are charged to expense when incurred.

(p) Accounting for derivatives and hedging activities

The Company applies SFAS No. 133 – Accounting for Derivative Instruments and Hedging Activities, together with its amendments and interpretations, referred to collectively herein as “SFAS 133”. SFAS 133 requires that all derivative instruments be recorded in the balance sheet of the Company as either an asset or a liability and measured at fair value. SFAS 133 requires that changes in the derivative’s fair value be recognized in the income statement unless specific hedge accounting criteria are met; and the Company designates. For derivatives designated as accounting hedges, fair value adjustments are recorded either in the income statements or Accumulated Other Comprehensive Income, a component of shareholders’ equity, depending upon the type of accounting hedge and the degree of hedge effectiveness.

(p) Accounting for derivatives and hedging activities (Continued)

The Company uses derivative financial instruments for economic hedging purposes to mitigate the risk of unfavorable price movements for crude oil purchases. These instruments are marked-to-market with the associated gains or losses recognized as Financial Income or Financial Expense.

The Company may also use derivative financial instruments for economic hedging purposes to mitigate the risk of unfavorable exchange-rate movements on its foreign currency-denominated funding. Gains and losses from changes in the fair value of these contracts are recognized as Financial Income or Financial Expense.

For cash flow hedges, the gains and losses associated with the derivative instruments are deferred and recorded in Accumulated Other Comprehensive Income until such time as the hedged transaction impacts earnings, with the exception of any hedge ineffectiveness; which is recorded directly in earnings.

(q) Recently issued accounting pronouncements

In July 2006, the FASB issued FIN 48, that clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a threshold of more-likely-than-not for recognition of tax benefits of uncertain tax positions taken or expected to be taken in a tax return. FIN 48 also provides related guidance on measurement, derecognition, classification, interest and penalties, and disclosure. The provisions of FIN 48 will be effective for the Company on January 1, 2007, with any cumulative effect of the change in accounting principle recorded as an adjustment to opening retained earnings. The Company is in the process of assessing the impact of adopting FIN 48 on its results of operations and financial position. The Company does not expect that the adoption of FIN 48 will have a material effect on the Company’s financial position or results from operations.

(q) Recently issued accounting pronouncements (Continued)

In September 2006, the FASB issued SFAS 157, which will become effective for the Company on January 1, 2008. This standard defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. SFAS 157 does not require any new fair value measurements but would apply to assets and liabilities that are required to be recorded at fair value under other accounting standards. The impact, if any, to the Company from the adoption of SFAS 157 in 2008 will depend on the Company’s assets and liabilities at that time that are required to be measured at fair value.

In February 2007, the FASB issued SFAS 159 “The Fair Value Option for Financial Assets and Financial Liabilities.” SFAS 159, that permits the measurement of certain financial instruments at fair value. Entities may choose to measure eligible items at fair value at specified election dates, reporting unrealized gains and losses on such items at each subsequent reporting period. SFAS 159 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the potential impact of the fair value option but it is not expected to have a significant effect on reported financial position or statements of income.

(r) Recently adopted accounting pronouncements

In September 2006, the FASB issued SFAS 158, which became effective for the Company on December 31, 2006. See Note 16(d).

3. Income Taxes

Income taxes in Brazil comprise federal income tax and social contribution, which is an additional federal income tax. The statutory enacted tax rates for income tax and social contribution have been 25% and 9%, respectively for the years ended December 31, 2006, 2005 and 2004.

The Company’s taxable income is substantially generated in Brazil and is therefore subject to the Brazilian statutory tax rate. The following table reconciles the tax calculated based upon statutory tax rates to the income tax expense recorded in these consolidated financial statements.

TRANSPORTADORA BRASILEIRA GASODUTO BOLÍVIA-BRASIL S.A. – TBG, a subsidiary of GASPETRO, has accumulated tax losses which have resulted in income tax and social contribution carryforwards amounting to US$345 as of December 31, 2006 (US$377 in 2005). These credits are being carried forward on a monthly basis against the taxes payable, in accordance with the existing legislation. These credits were accumulated between 1999 and 2002, based on a technical study approved by the Board of Directors on the expected generation of future taxable income and profitability in the past three years which allows realization thereof in ten years at the maximum.

PEPSA also has tax credits amounting to US$366 as of December 31, 2006 (US$443 in 2005), which could be offset against future taxable income and, for which a valuation allowance is recognized in the consolidated financial statements for December 31, 2006 and 2005. As of December 31, 2006, PEPSA has booked a US$335 allowance for tax loss carryforwards (US$352 in 2005) because, as of such dates, management believes that it is more likely than not that future taxable income will not be sufficient to absorb the net deductible temporary differences and accumulated tax loss carryforwards. These tax loss carryforwards have been generated mainly due to operating losses occurred during the Argentinean crisis in 2001 and 2002.

Annually PEPSA’s management evaluates the recovery of tax loss carryforwards taking into consideration, among other elements, the projected business profits, tax planning strategies, temporariness of future taxable income, considering the term of expiration of the loss carryforwards, the future reversions of the existing temporary differences and the recent-year tax history. All the evidence available both positive and negative is duly weighted and considered in the analysis.

At December 31, 2006 and 2005, the PEPSA’s management partially reversed the tax loss carryforward allowance booked in prior years recognizing a tax benefit of US$17 and US$63, respectively. PEPSA’s management will continue analyzing the feasibility of recovering the tax loss carryforwards for which the allowance was recognized.

The deferred tax amounts recorded are principally generated through transactions occurring in Brazil and there are no significant deferred tax amounts from international locations. There is no netting of taxes between international jurisdictions.

The major components of the deferred income tax accounts in the consolidated balance sheet are as follows:

Although realization of net deferred tax assets is not assured, management believes that, except where a valuation allowance has been provided, such realization is more likely than not to occur. The amount of the deferred tax asset considered realizable could, however, be reduced if estimates of future taxable income are reduced. Tax loss carryforwards generated in Brazil do not expire and are available for offset against future taxable income, limited to 30% of taxable income in any individual year. PEPSA tax loss carryfoward principally expire in years beyond 2007, and may be offset against future taxable income without limitation. The following presents the changes in the valuation allowance for the years ended December 31, 2006, 2005 and 2004:

             Year ended December 31, 
   
    2006    2005    2004

The Company has not recognized a deferred tax liability of approximately US$190 for the undistributed earnings of its foreign operations that arose in 2006 and prior years as the Company considers these earnings to be indefinitely reinvested. A deferred tax liability will be recognized when the Company no longer demonstrates that it plans to permanently reinvest the undistributed earnings. As of December 31, 2006 the undistributed earnings of these subsidiaries were approximately US$560.

Marketable securities are comprised primarily of amounts the Company has invested in an exclusive fund, excluding the Company’s own securities, which are considered repurchased. The exclusive fund is consolidated, and the equity and debt securities within the portfolio are classified as trading or available-for-sale under SFAS 115 based on management’s intent. Trading securities are principally Brazilian bonds, which are bought and sold frequently with the objective of making short-term-profits on market price changes. Available-for-sale securities are principally, LCN (Credit Liquid Note) agreements and certain other bonds for which the Company does not have current expectations to trade actively. Trading securities are presented as current assets, as they are expected to be used in the near term for cash funding requirements. Available-for-sale securities are presented as “other assets”, as they are not expected to be sold or liquidated within the next twelve months.

The Company holds National Treasury Bonds "Series P" (NTN-P) issued by the Federal Government which are accounted for as available-for-sale securities in accordance with SFAS 115.

6. Accounts Receivable, Net (Continued)

At December 31, 2006 and 2005, long-term receivables include US$608 and US$599 respectively relating to payments made by the Company to suppliers and subcontractors on behalf of certain contractors. These contractors had been hired by the subsidiary BRASOIL for the construction/conversion of vessels into FPSO (“Floating Production, Storage and Offloading”) and FSO (“Floating, Storage and Offloading”) and failed to make the payments to their suppliers and subcontractors. The Company made the payments to avoid further delays in the construction/conversion of the vessels and consequent losses to BRASOIL.

Based on consultations with legal advisers, the Company’s management has determined that these payments can be reimbursed, since they represent BRASOIL’s rights with respect to the contractors, for which reason judicial action was filed with international courts to seek reimbursement. However, as a result of the uncertainties related to the realization of such receivables, the Company recorded an allowance for all credits not backed by collateral. Such allowance amounted to US$536 and US$527 as of December 31, 2006 and 2005, respectively.

Less: Long-term recoverable taxes    (1,292)   (639)
     
 
Current recoverable taxes    2,593    2,087 
     

(1) Domestic value-added sales tax are composed of credits generated by commercial operations and by the acquisition of property, plant and equipment and can be offset with taxes of the same nature.

(2) PASEP and COFINS are social security contributions payable in respect of sales of products and services and financial revenues.

These contributions and the domestic value-added tax (ICMS) are not cumulative and amounts paid related to these taxes in the acquisition of products and/or services can be offset when these products and services are sold, which means a tax credit is generated when the purchase is made and such credit is then offset upon sale to final customer.

The income tax and social contribution recoverable will be offset against future taxable income.

Petrobras plans to fully recover these taxes, and as such, no allowance has been provided.

(b) New Hydrocarbons Law of Bolivia

The new Bolivian Hydrocarbons Law 3,058 has been in force since May 19, 2005. This law revokes the former Hydrocarbons Law 1,689 dated April 30, 1996.

The new law establishes, among other matters, a higher tax burden for companies of the sector, through royalties of 18% and a direct tax on hydrocarbons (IDH) of 32%, to be applied directly on 100% of the production, on top of taxes in force by operation of Law No. 843. In addition, the new legislation determines substitution of shared risk contracts for new contracts observing the models established in the Law, and introduces changes in the oil products distribution activity.

On May 20, 2005, contracts were entered into for association among Yacimientos Petrolíferos Fiscales Bolivianos - YPFB (Bolivian state-owned company) and fuel distribution companies to extend the term of Distributors’ operations up until YPFB accumulates sufficient funds to develop this segment all over the Bolivian territory. On June 30, 2006 the contracts term expired through which the major distribution companies distributed hydrocarbons in Bolivia. YPFB took over national distribution as from that date. The company Petrobras Bolívia Distribución, which allowed the ownership of a major part of this business, is still operating in the sector through the service stations it owns.

As of May 1, 2006, Supreme Decree 28,701 was enacted in Bolivia, through which, the natural hydrocarbon resources were nationalized. As a consequence, the companies that are currently engaged in gas and petroleum production activities, will have to transfer the ownership of all hydrocarbon production to Yacimientos Petrolíferos Fiscales Bolivianos (YPFB). A transition period has also been established of 180 days as from the date the aforementioned decree is enacted, in which companies that are currently operating should execute the new contracts established by YPFB. Companies which have not executed these contracts by the end of this term may be unable to continue operating in the country.

(b) New Hydrocarbons Law of Bolivia (Continued)

The aforementioned Decree establishes that fields with a certified average natural gas production of over 100 million cubic feet per day in 2005, as is the case with the San Alberto and San Antonio fields where the Company operates, an additional amount will be paid to YPFB of 32% over of the production value, rising to a total of 82% of the Bolivian government’s interest. The Bolivian Ministry of Hydrocarbons and Energy shall determine on a case-by-case basis via auditing the final share to be paid to the Companies in the contract to be executed. Up to December 31, 2006 the Company had recorded a provision to pay the additional share to YPFB of 32% on the hydrocarbon production, to an amount equal to US$99. The regulatory decrees which among other matters shall establish the means for paying this share have not yet been issued.

Furthermore, according to this decree the State is nationalizing the shares required for YPFB to control, with a minimum of 50% plus one share, Petrobras Bolívia Refinación S.A. - PBR, in which Petrobras has an indirect interest of 100% (Petrobras International Braspetro B.V. - 51% and Petrobras Energia S.A. - 49%). The equity interest will be transferred to YPFB when the parties reach an agreement about the amount of economic compensation to be paid by YPFB to Petrobras, besides the former compliance of some legal and statutory assumptions. The parties have not yet commenced the assessment process.

On October 28, 2006 Petrobras Bolívia and its partners executed operating contracts with YPFB for San Alberto and San Antonio fields. These contracts establish that the revenues, royalties, profit shares, IDH, shipment and compression will be absorbed by YPFB, and the cost of production and investments made by the companies should be reimbursed as remuneration to the owner. Any difference which may exist will be distributed between the Bolivian state company and the companies, at percentages varying according to production and the investment recovery factor. These contracts will come into force as from approval by the Bolivian National Congress and their official registration.

In a document attached to contracts entitled “Investments made”, Petrobras and its partners state the investment amounts net of amortization, which will be reviewed taking into account the results of the audits contracted by the Hydrocarbons Ministry, that are currently in progress. To date, the Company is not aware of the result of these audits and the possible effects on its investments.

Supreme Decree 28,900-A issued October 28, 2006 established that the companies will continue operating in Bolivia in accordance with Supreme Decree 28,701, including article 3, paragraph 1 which establishes the additional payment of 32% for the San Alberto and San Antonio fields until the aforementioned contracts have been registered.

On November 28, 2006 the National Congress approved the 44 oil contracts (exploration and production), which include the contracts that Petrobras participates in/or operates, which mainly include the San Alberto and San Antonio fields. On January 11, 2007 Laws were published by which the Bolivian Legislative Branch approved these contracts, including those referring to the San Alberto and San Antonio fields. To date the contracts have not been registered at a registry office, despite the fact there is no justifiable reason for the delay. The contracts will come into force after they have been effectively registered.

PBR and PEBIS continue their normal operations under the control and management of the Company, and hence their consolidated financial statements are still being included in the Company’s consolidated financial statements. The consolidated total assets balance of PEBIS as of December 31, 2006 amounted to US$1,173.

(c) Review of operating agreements in Venezuela

In March of 2006, PESA, through its controlled and associated companies in Venezuela, entered into Memoranda of Understanding (MOU) with PDVSA and Corporación Venezolana del Petróleo S.A. (CVP) in order to finalize the migration of operational agreements to mixed-capital companies. The MOUs establish that the interest of private partners in mixed-capital corporate companies should be limited to 40%, while the Venezuelan government participates with the remaining 60%. Thus, PESA’s indirect interest in the fields of Oritupano Leona, La Concepción, Acema and Mata Areas was defined as being of 22%, 36%, 34.5% and 34.5%, respectively.

Pursuant to the terms of the MOU, CVP shall acknowledge dividable and transferable credits in favor of the private companies with interest in the mixed-capital companies, which shall not be subject to interest and may be used in payment of the acquisition bonus of new areas for petroleum exploration and production activities or for a license to engage in gas exploration and production.

(c) Review of operating agreements in Venezuela (Continued)

During the transition period and until the mixed capital companies are in operation, the consortia’s operations have been conducted and supported by Petrobras Energia Venezuela under the supervision of an integrated operating committee, on which PDVSA representatives shall form the majority.

Due to the change in structure of shareholding interest in the mixed capital companies, from April 1, 2006 the Company no longer consolidates the assets, liabilities and results of the aforesaid operations in its consolidated statements, but presents them as equity investments in non-consolidated companies and other investments, which increased the balance of such account by US$878.

(d) New Hydrocarbons Law in Ecuador

In April 2006, the Law which amended the Hydrocarbons Law (Ley de Hidrocarburos) was enacted in Ecuador, which establishes the Government shall hold a minimum share of 50% in the extraordinary revenues, generated by increases to the sale price of Ecuadorian oil (average monthly effective FOB sale price) as compared to the monthly average oil sale price established in the contract, stated in the currency of the month of settlement. In July, 2006 the regulations of said Law were published which Ecuadortlc S.A., a subsidiary of PESA, and Petroecuador interpreted differently. The application of this law is being disputed by Ecuadortlc and Petroecuador.

(e) SFAS No. 143 - Accounting for asset retirement obligations

Since January 1, 2003, Petrobras adopted SFAS No. 143 - Accounting for Asset Retirement Obligations ("SFAS 143"). Under SFAS 143, the fair value of asset retirement obligations are recorded as liabilities on a discounted basis when they are incurred, which is typically at the time the related assets are installed. Amounts recorded for the related assets will be increased by the amount of these obligations and depreciated over the related useful lives of such assets. Over time, the amounts recognized as liabilities will be accreted for the change in their present value until the related assets are retired or sold.

Measurement of asset retirement obligations is based on currently enacted laws and regulations, existing technology and site-specific costs. There are no assets legally restricted to be used in the settlement of asset retirement obligations.

During 2005, the impairment charge was primarily related to investments in Venezuela (US$134), due to the tax and legal changes implemented by the Ministry of Energy and Petroleum of Venezuela (MEP), previously mentioned. During 2004, the impairment charge was related to producing properties in Brazil, principle amounts were related to the Company’s Cioba’s off-shore field (US$30). The impairment expenses recorded in 2004 were primarily due to capital expenditures made in 2004 to producing fields with only marginal reserves.

The contract established in its 4th clause that the parties receiving the shares of EG3 and REFAP should, in the course of eight years after January 1, 2001, review every year the reference values of EG3 Group and REFAP S.A. (denominated “escalators”) to adjust them observing the conditions of said clause and to allow determining at the end of the period the definitive value of the shares of EG3 and REFAP, as well as definitive assets position and payment thereof to the creditor, under common agreement between the parties.

Petrobras and Petrobras Finance Ltd. - PFL have certain contracts (Master Export Contract and Prepayment Agreement) between themselves and a special purpose entity not related to Petrobras, PF Export Receivables Master Trust (“PF Export”), relating to the prepayment of export receivables to be generated by PFL by means of sales on the international market of fuel oil and other products acquired from Petrobras.

As stipulated in the contracts, PFL assigned the rights to future receivables in the amount of US$1,800 (1st and 2nd tranches) to PF Export, which, in turn, issued and delivered to PFL the following securities, also in the amount of US$1,800:

The assignment of rights to future export receivables represents a liability of PFL, which will be settled by the transfer of the receivables to PF Export as and when they are generated. This liability will bear interest on the same basis as the Senior and Junior Trust Certificates, as described above. The Junior Trust Certificates form a 20% guarantee to the Senior Trust Certificates.

On September, 2005 Petrobras prepaid an amount of US$330 to PETROBRAS FINANCE LTD. – PFL respective to the export prepayments. Subsequent, PETROBRAS FINANCE LTD. – PFL paid on September 1, 2005 an equal amount related to the Senior Trust Certificates series A2 and C with floating rates, issued by PF Export, maturing on 2010 and 2013, respectively.

The Company’s debt agreements contain affirmative covenants regarding, among other things, provision of information; financial reporting; conduct of business; maintenance of corporate existence; maintenance of government approvals; compliance with applicable laws; maintenance of books and records; maintenance of insurance; payment of taxes and claims; and notice of certain events. The Company’s debt agreements also contain negative covenants, including, without limitation, limitations on the incurrence of indebtedness; limitations on the incurrence of liens; limitations on transactions with affiliates; limitations on the disposition of assets; limitation on consolidations, mergers, sales and/or conveyances; negative pledge restrictions; change in ownership limitations; ranking; use of proceeds limitations; and required receivables coverages. Petrobras’ management affirms that the Company is in compliance with the covenants within debt agreements.

At December 31, 2006 and 2005, GASPETRO had secured certain debentures issued to finance the purchase of the transportation rights in the Bolivia/Brazil pipeline with 3,000 shares of its interest in TBG, a subsidiary of GASPETRO responsible for the operation of the pipeline.

The Federal Government guarantees TBG’s Multilateral Credit Agency debt, which had an outstanding balance of US$367 and US$402 at December 31, 2006 and 2005, respectively. During 2000, the Federal Government, the Company, TBG, PETROQUISA and Banco do Brasil S.A. entered into an agreement whereby the revenues of TBG will serve as a counter-guarantee to this debt until the debt has been extinguished.

Petrobras entered into standby purchase agreements in support of the obligations of its wholly-owned subsidiary, PIFCo, under the note issuances in 2001, 2002 and 2003 and their respective indentures. Petrobras has the obligation to purchase from the noteholders any unpaid amounts of principal, interest or other amounts due under the notes and the indenture applies, subject to certain limitations, irrespective of whether any such amounts are due at maturity of the notes or otherwise.

14. Project Financings

Since 1997, the Company has utilized project financings to provide capital for the continued development of the Company’s exploration and production and related projects.

The special purpose entities associated with the project finance projects are consolidated based on FIN 46(R) and the project financing obligation represents the debt of the consolidated SPEs with the third-party lender.

The Company’s responsibility under these contracts is to complete the development of the oil and gas fields, operate the fields, pay for all operating expenses related to the projects and remit a portion of the net proceeds generated from the fields to fund the special purpose companies’ debt and return on equity payments. At the conclusion of the term of each financing project, the Company will have the option to purchase the leased or transferred assets from the consolidated special purpose company.

The following summarizes the liabilities related to the projects that were in progress at December 31, 2006 and 2005:

(b) Pension plan - Fundação Petrobras de Seguridade Social – PETROS (Continued)

The PETROS plan is a contributory defined-benefit pension plan introduced by Petrobras in July of 1970, to supplement the social security pension benefits of employees of Petrobras and its Brazilian subsidiaries and affiliated companies. In order to fund its objectives, PETROS receives monthly contributions from the sponsoring companies of the PETROS Plan amounting to 12.93% of the salaries of participants in the plan. Additionally PETROS is funded by income resulting from the investment of these contributions. The Company’s funding policy is to contribute to the plan annually the amount determined by actuarial calculations. In the calendar 2006 year, benefits paid totaled US$713 (US$570 in 2005).

The Company’s liability related to future benefits to plan participants is calculated on an annual basis by an independent actuary, based on the Projected Unit Credit method. The assets that guarantee the pension plan are presented as a reduction to the net actuarial liabilities.

The actuarial gains and losses generated by the differences between the values of the obligation and assets determined based on projections and the actual figures, are respectively included or excluded from the calculation of the net actuarial liability and recorded as “Postretirements benefit reserves adjustments net of tax - pension cost”, in shareholders’ equity. Actuarial gains and losses are amortized during the average remaining service period of the active employees of approximately 10 years at December 31, 2006, in accordance with the procedure established by SFAS 87.

The relation between contributions by the sponsors and participants of the PETROS Plan, considering only those attributable to the Company and subsidiaries in the 2006 and 2005 financial years, was 1.00 to 1.00. The Company’s best estimate of contributions expected to be paid in 2007 respective to the pension plan approximates US$194, with total pension benefit payments in 2007 expected to be US$830.

According to Constitutional Amendment No. 20, the computation of any deficit in the defined-benefit plan in accordance with the actuarial method of the current plan (which differs from the method defined in SFAS 87), must be equally shared between the sponsor and the participants, by an adjustment to the normal contributions.

Plan assets (Continued)

The Company uses 6.19% as the expected long-term rate of return over inflation on PETROS’ assets. The PETROS’ portfolio of investments as of December 31, 2006 was comprised of 71% securities, 44% of which were held-to-maturity government securities that earn interest at 6% annually plus the IPCA (Consumer Price Index) variation and 27% of which were Investments Funds that earn interest approximate to the CDI (Certificado de Depósito Interbancário, or Interbank Deposit Certificate), which has been yielding more than 6% annually. Thus, the Company considers a 6.19% long term interest rate appropriate to calculate the expected return on assets, as such aligns with the composition of the PETROS’ asset portfolio.

PETROS has a significant volume of investments in government securities, mainly NTN-B bonds, which by an agreement with the Supplementary Social Security Department will be held-to-maturity being recorded at fair value, for which a net present adjustment was required. Thus, the percentage of assets allocated in this investment will remain the same over the short term.

New benefits plan

In May of 2001, the Board of Directors of Petrobras approved the creation of a mixed social security plan, for current and new employees, based on defined contribution formula for programmable benefits and a defined benefit formula for risk benefits. However, the migration of participants and beneficiaries of the previous plan (PETROS) to the new plan was suspended, pursuant to a Federal Judicial ruling arising from an injunction filed by the employee union. A court order in 2004 granted the injunction ruling against the new plan and invalidating any changes to the PETROS plan premised upon intended migration to a new plan. This court decision is under appeal.

In 2003, the Company formed a task force with representatives of the National Union of Oil Workers (FUP), unions and PETROS, among others, in order to evaluate alternatives to a new model for the Company’s supplementary pension plan, including analyses of negotiated arrangements for the settlement of actuarial deficits.

New benefits plan (Continued)

On April 19, 2006, the Company, aiming to achieve an agreement regarding its Supplementary Pension Plan, presented to employee participants and retirees a proposal to bring equilibrium to the actual PETROS Plan and the implementation of a new plan, denominated PETROS Plan 2.

Execution of the proposal presented by the Company’s Executive Board was subject to a number of conditions, including the renegotiation of the PETROS Plan Regulations, in relation to the means of readjusting the benefits and pensions, considering a significant rate of individual accession of employees and dependants.

The overall renegotiation target previously set by the Company had not been achieved. As a result the proposal presented by Petrobras became null and void.

On January 08, 2007, the Petrobras Board of Directors approved the reopening of the PETROS Plan renegotiation process, in order to meet the claims of the trade unions, as most participants were in favor of the renegotiation.

The new target for the minimum accession number to the renegotiation was set at 2/3 (two-thirds) of the members and the final deadline for them to make their choice was February 28, 2007. The renegotiation target was met and the proposal submitted by the Company became effective, and PETROS is calculating the amounts to be funded by the sponsors, that will reduce the deficit of the PETROS Plan, as established by Brazilian pension law.

On October 20, 2006, the Board of Directors of Petrobras approved the introduction of PETROS Plan 2 for employees currently with no pension plan.

The New Supplementary pension plan was formulated according to the Variable Contribution model. In this model, the contributions are capitalized in individuals accounts, and the pension benefits are established according to the account balances. This plan also includes risk benefits with coverage for illness, incapacity and death, and a lifetime income.

New benefits plan (Continued)

The PETROS Plan 2 also includes a minimum benefit for payment of annuities which guarantees coverage of the benefit to ensure it does not have a monetary value of under 30% of the average contribution salary.

On December 20, 2006 the Department for Coordinating and Controlling State Companies (DEST) decided to approve the proposed PETROS Plan 2, which was also approved on January 05, 2007 by the Ministry of Mines and Energy.

On January 19, 2007, the PETROS Decision-making Board approved the PETROS Plan 2, which will be referred for assessment and statement by the Supplementary Pensions Office - SPC, for the proper final approval, whereupon it may be offered to the employees who are not presently covered by a supplementary pension plan sponsored by the Company.

Petrobras and the other sponsors will fully assume the contributions corresponding to the period in which the new participants had no plan. This past service shall consider the period from the date of admission to the date enrolment commenced in the PETROS Plan 2. The disbursements will be conducted over the first months for contributions up to the total months the participant had no plan, and shall cover the portion relating to the participants and sponsor. The maximum estimated value of this actuarial commitment as of December 31, 2006 if the plan is approved by SPC and accepted by all new employees was US$109.

This New Plan also allows the Company to maintain the pension coverage it offers, mitigates the risks presented by the defined benefit model adopted and considerably reduces the possibility of future deficits. The impact of joining the new plan and its related benefit costs will be valued according to the standards established in SFAS 87, 132 and 158 and will only be computed and recognized in the accounts when the plan is implemented.

TRANSPETRO

TRANSPETRO maintains a defined-contribution private pension scheme with PETROS called Plano TRANSPETRO, which receives monthly contributions equivalent to 5.32% of the payroll of the members and is equal to the contributions made by the participants.

(c) PETROBRAS ENERGIA – PEPSA (including PESA)

Defined contribution plan

Supplementary Pension Plan for Personnel

In November 2005, the Board of Directors of Petrobras Energía approved the implementation of a defined voluntary contributions plan which all of the Company’s employees may elect to join Petrobras Energia. Through this plan, Petrobras Energía will make contributions to a trust equivalent to the contributions made by the employees that will subscript to the plan to a mutual fund or AFJP, at their choice, in conformity with a scheme defined for each salary level. The participating employees may make voluntary contributions exceeding those established in the mentioned scheme, which will not be considered for purposes of the contributions to be made by Petrobras Energia.

In the fiscal years ended December 31, 2006 and 2005, Petrobras Energía recorded an expense of US$3 and US$7, respectively, attributable to such benefits.

Defined benefit plan

Indemnity Plan

This is a defined benefit plan for all the employees who fulfill certain conditions, and consists of granting, upon retirement, a one-month salary per years of service at the Company, in conformity with a decreasing scale considering the years of effectiveness of the plan.

Compensating Fund

This is a defined benefit plan for all employees of Petrobras Energía who have joined the Company prior to May 31, 1995, and have reached a certain number of years of service. The employee benefit is based on the last computable salary and years of service of each employee included in the fund.

The plan is of a supplemental nature, that is to say the benefit to the employee is represented by the amount determined under the provisions of this plan, after deducting benefits payable to the employee under the contribution plan and the public retirement system, in order that the aggregate benefit to each employee equals the one stipulated in this plan.

(c) PETROBRAS ENERGIA – PEPSA (including PESA) (Continued)

Defined benefit plan (Continued)

The plan calls for a contribution to a fund exclusively by Petrobras Energía and without any contribution by the employees, provided that they should make contributions to the retirement system for their whole salary. As provided in Petrobras Energía’s By-laws, the Company makes contributions to the fund on the basis of a Board of Directors’ proposal to the Shareholders’ Meeting up to 1.5% of net income for each year. The assets of the fund were contributed to a trust. The goals with respect to asset investment are: (i) the preservation of capital in US dollars, (ii) the maintenance of high levels of liquidity, and (iii) the attainment of the highest yields possible on a 30-days basis. For this reason, the assets are invested mainly in bonds, corporate bonds, mutual funds, and certificates of deposits. The Bank of New York is the trustee and Watson Wyatt is the managing agent. Should there be an excess (duly certified by an independent actuary) of the funds under the trust agreement to be used to settle the benefits granted by the plan, Petrobras Energía will be entitled to make a choice and use it, in which case it would have to notify the trustee thereof.

(d) SFAS 158 - “Employers” Accounting for Defined Benefit Pension and Other Postretirement Plans

In September 2006, the FASB issued SFAS 158 - “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans — an Amendment of FASB Statements No. 87, 88, 106 and 132(R)” (“SFAS 158”), which became effective for the Company on December 31, 2006. This standard requires the Company to recognize the overfunded or underfunded status of each of its defined benefit pension and other postretirement benefit plans as an asset or liability and to reflect changes in the funded status through “Accumulated other comprehensive income,” as a separate component of shareholders’ equity.

(e) Health care benefits - “Assistência Multidisciplinar de Saúde” (AMS)

Petrobras and its Brazilian subsidiaries maintain a health care benefit plan (AMS), which offers defined benefits and covers all employees (active and inactive) together with their dependents. The plan is managed by the Company, with the employees contributing fixed amounts to cover principal risks and a portion of the costs relating to other types of coverage in accordance with participation tables defined by certain parameters including salary levels.

The Company's commitment related to future benefits to plan participants is calculated on an annual basis by an independent actuary, based on the Projected Unit Credit method. The health care plan is not funded or otherwise collateralized by assets. Instead, the Company makes benefit payments based on annual costs incurred by plan participants.

(e) Health care benefits - “Assistência Multidisciplinar de Saúde” (AMS) (Continued)

Until 2006, the actuarial gains and losses generated by the differences between the values of the obligation determined based on projections and the actual figures, were respectively included or excluded when defining the net actuarial obligation.

As of December 31, 2006, according to SFAS 158 (See Note 16(d)), the actuarial gains and losses generated by the differences between the values of the obligation determined based on projections and the actual figures, are respectively included or excluded from the calculation of the actuarial obligation and recorded as “Postretirements benefit reserves adjustments net of tax- health care cost”, as Accumulated Other Comprehensive Income,in shareholders’ equity.

The gains and losses recorded as Accumulated Other Comprehensive Income are amortized over the average remaining service period of the active employees.

Upon adoption of SFAS 158, as of December 31, 2006 the liabilities related to health care increased by US$1,495 and shareholders’ equity reduced by US$987, net of income taxes.

On December 15, 2006, Petrobras implemented the Medicine Benefit, which provides special terms on the acquisition of certain medicines by members of the AMS from participating drugstores, located throughout Brazil.

Following the introduction of this benefit, the unrecognized prior service cost estimated by independent actuary, as of December 31, 2006 was US$86, and wil be amortized over the average remaining service period of the active employees. The unrecognized prior service cost was included in Accumulated Other Comprehensive Income and presented in Change in Benefit Obligations, as “Plan Amendments”.

For measurement purposes, a 10% annual rate of increase in the per capita cost of covered health care benefits was assumed upon adoption of SFAS 106. The annual rate was assumed to decrease to 4.5% from 2007 to 2036.

Petrobras has aggregated information for all defined benefit pension plans. The domestic benefit plans of Petrobras, BR Distribuidora, PETROQUISA, and REFAP contain similar assumptions and the benefit obligation related to PEPSA, the international plan, is not significant to the total obligation and thus has also been aggregated. All Petrobras group pension plans have accumulated benefit obligation in excess of plan assets.

(f) Funded status of the plans (Continued)

The determination of the expense and liability relating to the Company’s pension plan involves the use of judgment in the determination of actuarial assumptions. These include estimates of future mortality, withdrawal, changes in compensation and discount rate to reflect the time value of money as well as the rate of return on plan assets. These assumptions are reviewed at least annually and may differ materially from actual results due to changing market and economic conditions, regulatory events, judicial rulings, higher or lower withdrawal rates or longer or shorter life spans of participants.

According to the requirements of SFAS 87, and subsequent interpretations, the discount rate should be based on current prices for settling the pension obligation. Applying the precepts of SFAS 87 in historically inflationary environments such as Brazil creates certain issues as the ability for a company to settle a pension obligation at a future point in time may not exist as long-term financial instruments of suitable grade may not exist locally as they do in the United States.

Although the Brazilian market has been demonstrating signs of stabilization under the present economic model, as reflected in market interest rates, it is not yet prudent to conclude that market interest rates will be stable.

In 2004, Petrobras approved a change to a new mortality table of the actuarial assumptions of the pension and healthcare plans in Brazil; this new mortality table reflects updated assumptions and changes relative to the profile of employees, retirees and pensioners, based on longevity, age of invalidity and invalid mortality tables.

(g) Cash contributions and benefit payments

In 2006, the Company contributed US$187 to its pension plans. In 2007, the Company expects contributions to be approximately US$194. Actual contribution amounts are dependent upon investment returns, changes in pension obligations and other economic factors. Additional funding may ultimately be required if investment returns are insufficient to offset increases in plan obligations.

(a) Capital

The Company’s subscribed and fully paid-in capital at December 31, 2006 consisted of 2,536,673,672 common shares and 1,850,364,698 preferred shares, and at December 31, 2005 consisted of 2,536,673,672 common shares and 1,849,478,028 preferred shares, as retroactively restated for stock split, mentioned below. The preferred shares do not have any voting rights and are not convertible into common shares and vice-versa. Preferred shares have priority in the receipt of dividends and return of capital.

On May 13, 2005, Petrobras management approved the proposed share split and the related amendment to article 4 of the Company’s by-laws. These issues were discussed by the shareholders at the Extraordinary General Meeting (EGM) held on June 15, 2005.

The Extraordinary General Meeting held on July 22, 2005 decided to effect a split of each Company’s share into four, resulting in a free distribution of 3 (three) new shares of the same type for each original share, based on the shareholding structure at August 31, 2005. At the same date, an amendment to article 4 of the Company’s by-laws to cause capital be divided into 4,386,151,700 shares, of which 2,536,673,672 are common shares and 1,849,478,028 are preferred shares, with no nominal value, was approved. This amendment to the Company’s bylaws is effective from September 1, 2005.

The relation between the American Depository Receipt (ADS) and shares of each class was changed from one to four shares for one ADS. All share and per share information in the accompanying financial statements and notes has been adjusted to reflect the result of the share split.

Current Brazilian law requires that the Federal Government retain ownership of 50% plus one share of the Company’s voting shares.

Shareholders at the Extraordinary General Meeting held June 01, 2006 approved the incorporation of shares in PETROQUISA by Petrobras, pursuant to the re-ratification of the Protocol of Merger and Incorporation on the share incorporation transaction executed by the two companies. The Board of Directors of the Company approved the issue of 886,670 preferred shares of the Company in connection with the incorporation of shares in PETROQUISA by Petrobras.

To implement the transaction, the exchange ratio for the shares to be used was based on the net equity value of both companies at the base date of December 31, 2005, when 4.496 preferred shares issued by Petrobras were attributed to each batch of 1,000 common or preferred shares issued by PETROQUISA.

No Petrobras’ shareholders had stated their intention to exercise the right withdraw by the legal deadline of July 07, 2006. Five PETROQUISA’s shareholders with a total interest of 1,015,910 shares exercised the right to withdraw by the established deadline (by July 05, 2006) and were reimbursed at the rate of R$153.47 (US$71) per batch of 1,000 shares, using funds provided by PETROQUISA, on July 10, 2006. Petrobras then acquired the shares for the same price, thereby transferring ownership.

On December 15, 2006, pursuant to article 29, section II of the Company By-laws, the Board of Directors authorized the buyback of part of the preferred shares in circulation for future cancellation, using funds from the profit reserves subject to the following terms:

In line with its share buyback policy, the Board of Directors concluded the current cash situation enables this project to be implemented without compromising the dividend payment and the investment program, while maintaining the operating and financial targets established in the Strategic Plan.

At an Extraordinary General Meeting held together with the General Ordinary Meeting, on April 2, 2007, the shareholders of Petrobras approved an increase in the Company’s capital to US$24,623 (R$52,644) through the capitalization of revenue reserves accrued during previous financial years, in the amount of US$1,577 (R$3,372), and of statutory reserve, in the amount of US$471 (R$1,008), and without the issuance of new shares, in accordance with article 169, paragraph 1, Law No. 6.404/76.

(b) Dividends and interest on shareholders’ equity (Continued)

Brazilian corporations are permitted to attribute interest on shareholders’ equity, which may either be paid in cash or be used to increase capital stock. The calculation is based on shareholders’ equity amounts as stated in the statutory accounting records and the interest rate applied may not exceed the Taxa de Juros de Longo Prazo (long-term interest rate or the "TJLP") as determined by the Brazilian Central Bank. Such interest may not exceed the greatest of 50% of net income or 50% of retained earnings plus revenue reserves.

(l) TermoMacaé Ltda. and TermoMacaé Comercializadora de Energia Ltda. (former Macaé Merchant)

In February 2005, the arbitration proceedings began related to the dispute between Petrobras and El Paso arising from the economic and financial imbalance deemed to exist relative to the construction and operation of the Macaé Merchant Thermoelectric Plant. Petrobras claims such contract to be invalid and require renegotiation as a result of changed economics.

(a) Litigation (Continued)

As of December 31, 2006 and 2005, in accordance with Brazilian law, the Company had paid US$816 and US$775, respectively, into federal depositories to provide collateral for these and other claims until they are settled. These amounts are reflected in the balance sheet as restricted deposits for legal proceedings and guarantees.

The Company is a party to several contracts related to the acquisition and upgrade of production Platform P-36, which was lost in its entirety in 2001. Pursuant to those contracts, the Company had an obligation to pay the insurance proceeds to a Security Agent for distribution according to specified clauses established in the contracts. The Company contends that it is entitled to the insurance proceeds under the contractual arrangements, and other parties contend that they are also entitled to such proceeds. The issue is subject to international proceedings in a British court. Pending determination of the issue by the international court, the Company committed to deposit cash collateral in the amount of US$175, in order to facilitate the issuance of a guarantee by a Security Agent, for the payment of creditors. At December 31, 2006, this amount was included in the balance sheet as restricted deposits for legal proceedings and guarantees.

Plaintiff: Kallium Mineração S.A.

On May 28, 1981, Kallium Mineração S.A. brought an action against Petromisa, a former subsidiary of Petrobras, in the Federal Court of the State of Rio de Janeiro alleging damages of approximately US$450 relating to the rescission of a contract to develop a potassium salt mine. On August 10,1999, a decision was handed down that considered most of the plaintiff’s petitions to be without grounds (losses, damages and loss of profit), requiring only the Company to reimburse “all expenses incurred as a result of the prospecting research” carried out, in accordance with amounts to be calculated in the final award. No award for loss of profit was established in the decision. In September of 1999 both parties filed appeals with the appeals court in the state of Rio de Janeiro. Granted by the lower court, both parties filed appeals, which were rejected. Petrobras is awaiting judgment of the Extraordinary Appeal filed before the STF and the special appeal on December 18, 2003. A special appeal brought by Kallium is also pending judgment. Based on the opinion of its legal advisers, management does not expect an unfavorable outcome in this case and considers the risk of loss with respect to this lawsuit to be possible.

(a) Litigation (Continued)

Plaintiff: PORTO SEGURO IMÓVEIS LTDA.

On November 23, 1992, PORTO SEGURO IMÓVEIS LTDA., a minority shareholder of PETROQUISA, filed a suit against Petrobras in the State Court of Rio de Janeiro related to alleged losses resulting from the sale of a minority holding by PETROQUISA in various petrochemical companies included in the National Privatization Program introduced by Law No. 8,031/90.

In this suit, the plaintiff claims that Petrobras, as the majority shareholder in PETROQUISA, should be obliged to reinstate the “loss” caused to the net worth of PETROQUISA, as a result of the acts that approved the minimum sale price of its holding in the capital of privatized companies. A decision was handed down on January 14, 1997 that considered Petrobras liable with respect to PETROQUISA for losses and damages in an amount equivalent to US$3,406.

In addition to this amount, Petrobras was required to pay the plaintiff 5% of the value of the compensation as a premium (see art. 246, paragraph 2 of Law No. 6,404/76), in addition to attorneys’ fees of approximately 20% of the same amount. However, since the award would be payable to PETROQUISA and Petrobras holds 99.0% of its capital, the effective disbursement if the ruling is not reversed will be restricted to 25% of the total award. Petrobras filed an appeal with the State Court of Rio de Janeiro, and received a favorable decision from the Third Civil Court on February 11, 2003, which, by a majority vote, accepted Petrobras’ appeal to reverse the judgment and ruled the plaintiff’s case to be without grounds, the revising judge’s decision that held the case to be partially with grounds to reduce the amount of compensation to US$1,538 being overruled. Against this decision, Porto Seguro filed another appeal (motion to reverse or annul) with the State Court of Rio de Janeiro, and the Fourth Civil Court handed down a unanimous decision on March 30, 2004 requiring Petrobras to indemnify PETROQUISA and Porto Seguro the amounts of US$2,359 and US$590 respectively (the latter representing 5% in premium and 20% in attorney’s fees). Due to this result, Petrobras lodged appeal with high and supreme courts, which was dismissed. In view of this decision, interlocutory appeal was filed with High Court - STJ and Supreme Court - STF, which was converted into Special Appeal by STJ.

Plaintiff: PORTO SEGURO IMÓVEIS LTDA. (Continued)

On May 6, 2005, the Superior Court of Justice (STJ) accepted the interlocutory appeal and determined that the special appeal was to be proceeded with. Porto Seguro lodged an appeal against the interlocutory decision, which was accepted by a majority vote on December 15, 2005, and suspension of the special appeal filed by Petrobras was reinstated. The Company filed an Interlocutory appeal against this latest decision, which was ruled on April 4, 2006 and which unanimously overturned a decision which restored the impediment on the Special Appeal brought by Petrobras, due to an impediment on one of the justices, determining another decision be pronounced. Special Appeal by PORTO SEGURO rejected under a judgment delivered on September 05, 2006. In performance of the decision published on June 05, 2006, we are now awaiting assignment of the agenda to reexamine the matter relating to the blocking of Petrobras’ Special Appeal. If the award is not reversed, the indemnity estimated to PETROQUISA, including monetary correction and interest, would be US$4,612. As Petrobras owns 100% of PETROQUISA’s share capital, a portion of the indemnity estimated at US$3,044, will not represent a disbursement from Petrobras’ Group. In case of loss, Petrobras would have to pay US$201 to Porto Seguro and US$922 to Lobo & Ideas by means of attorney’s fees, however based on the opinion of its legal advisers, the Company does not expect to obtain an unfavorable ruling in this case and considers the risk of loss with respect to this lawsuit to be possible.

(a) Litigation (Continued)

Plaintiff: The Fisherman’s Federation of the State of Rio de Janeiro (FEPERJ)

The Fisherman’s Federation of the State of Rio de Janeiro (FEPERJ) filed a civil suit against the Company with the Rio de Janeiro State Court for compensation of miscellaneous damages amounting to US$224, which it is claiming in the name of its members, as a result of the oil spill in Guanabara Bay on January 18, 2000. At that time, Petrobras paid out extrajudicial indemnification to everyone who proved to be fishermen when the accident occurred. According to the records of the national fishermen’s register, only 3.339 could claim indemnification. A decision was handed down on February 7, 2002 which ruled the claim partially without grounds, rejecting pain and suffering, and requiring the Company to pay compensation for material damages and loss of profit to be calculated at the award phase. The ruling expressly declares that it is not reasonable to consider an award based on the amount claimed, since it was without economic base. On February 02, 2007 a decision, partly accepting the expert report, was published. That expert report was prepared to stablish the parameters for calculating the award, which amounts to US$516 at that date. Petrobras will appeal before Rio de Janeiro’s Supreme Court, because the parameters set in the decision differs from those already defined by that same court. In accordance with the Company’s expert assistant calculation, the recorded amount of US$12 represents the award that will be set by the court at the end of the process. Based on its legal counsels opinion, the Company´s Administration believes it is possible that the Company will not prevail in this case.

Plaintiff: São Paulo State tax authorities

The São Paulo tax authorities filed a tax suit against the Company, to demand payment of ICMS on naphta-petrochemical operations carried out in the state for the period from September 1984 to February 1989.

The case was settled and the Company entered into an agreement to pay US$122 plus interest, totaling US$151, in 60 equal successive installments beginning April 2005.

Plaintiff: Distribution Companies

The Company was sued in court by certain small oil distribution companies under the allegation that it does not pass on to state governments the State Value-Added Tax (ICMS) collected according to the legislation upon fuel sales. These suits were filed in the states of Goiás, Tocantins, Bahia, Pará, Maranhão and in the Federal District.

Of the total amount related to legal actions of approximately US$419, up to December 31, 2006 some US$38 (US$34 in 2005) had been withdrawn from the Company’s accounts as a result of judicial rulings of advance relief, which were annulled as a result of an appeal filed by the Company.

The Company, with the support of the state and federal authorities, has succeeded in stopping the execution of other withdrawals, and is making all possible efforts to obtain reimbursement of the amounts that were previously withdrawn from its accounts.

(b) Notification from the INSS - joint liability

The Company received various tax assessments related to social security amounts payable as a result of irregularities in presentation of documentation required by the INSS, to eliminate its joint liability in contracting civil construction and other services, stipulated in paragraphs 5 and 6 of article 219 and paragraphs 2 and 3 of article 220 of Decree No. 3,048/99.

In order to guarantee the appeals’ filing and/or the obtainment from INSS of Debt Clearance Certificate, US$55 from the amounts disbursed by the Company is recorded as sheet as restricted deposits for legal proceedings and guarantees and may be recovered under the respective proceedings in progress, which are related to 343 assessments amounting to US$178. Petrobras’ legal department expects a possible defeat regarding these assessments, as it considers the risk of future disbursement to be possible.

Plaintiff: Internal Revenue Service of Rio de Janeiro – Withholding Tax related to charter of vessels

The Internal Revenue Service of Rio de Janeiro filed two Tax Assessments against the Company in connection with Withholding Tax (IRRF) on foreign remittances of payments related to charter of vessels of movable platform types for the years 1998 through 2002.

The Internal Revenue Service, based on Law No. 9,537/97, Article 2, considers that drilling and production platforms cannot be classified as sea-going vessels and therefore should not be chartered but leased. Based on this interpretation, overseas remittances for servicing chartering agreements would be subject to withholding tax at the rate of 15% or 25%.

The Company disagrees with the Internal Revenue Service’s interpretation as to charter contracts, given that the Federal Supreme Court has already ruled that, in the context of its judgment with respect to the IPI (Federal VAT) tax, offshore platforms are to be classified as sea-going vessels. Additionally, the 1994 and 1999 Income Tax Regulations support the “non-taxation” (RIR/1994) and the “zero tax rate” (RIR/1999) for the remittances in question.

On June 27, 2003, the Internal Revenue Service served a tax assessment notice on the Company amounting to R$3,064 million (US$1,066) covering the period from 1999 to 2002. Using the same arguments, on February 17, 2003, another tax assessment notice had already been issued for R$93 million (US$32) with respect to 1998, against which, on March 20, 2003, the Company filed an appeal. According to the fiscal authorities, the Company should have withheld that tax, incident on remittances made to abroad for payment of the hiring of vessels of the mobile platform type, used in oil exploration and production.

20. Derivative Instruments, Hedging and Risk Management Activities

The Company is exposed to a number of market risks arising from its normal course of business. Such market risks principally involve the possibility that changes in interest rates, foreign currency exchange rates or commodity prices will adversely affect the value of the Company's financial assets and liabilities or future cash flows and earnings. The Company maintains a corporate risk management policy that is executed under the direction of the Company's executive officers.

108


Table of Contents

20. Derivative Instruments, Hedging and Risk Management Activities (Continued)

The Company may use derivative and non-derivative instruments to implement its corporate risk management strategy. However, by using derivative instruments, the Company exposes itself to credit and market risk. Credit risk is the failure of a counterparty to perform under the terms of the derivative contract. Market risk is the possible adverse effect on the value of an assets or liability, including financial instruments that results from changes in interest rates, currency exchange rates, or commodity prices. The Company addresses credit risk by restricting the counterparties to such derivative financial instruments to major financial institutions. Market risk is managed by the Company's executive officers. The Company does not hold or issue financial instruments for trading purposes.

In 2004, the Petrobras Executive Board organized a Risk Management Committee comprising executive managers of all business areas and of several corporate areas for the purpose of ensuring integrated management of risk exposures and formalization of the main guidelines adopted by the Company to manage significant risks and uncertainties associated with its activities. The Risk Management Committee was created with a view towards concentrating risk management information and discussions and facilitating communications with the Board of Directors and the Executive Board.

(a) Foreign currency risk management

The Company’s foreign currency risk management strategy may involve the use of derivative instruments to protect against foreign exchange rate volatility which may impact the value of certain of the Company’s obligations.

During 2000, the Company entered into three zero cost foreign exchange rate collars to reduce its exposure to variations between the U.S. Dollar and the Japanese Yen, and between the U.S. Dollar and the EURO, relative to long-term debt denominated in foreign currencies with a face value of approximately US$470. The Company did not apply hedge accounting for these relationships. The collars were constructed by the simultaneous purchase of a call option and sale of a put option with the same counterparty and with equal premiums.

20. Derivative Instruments, Hedging and Risk Management Activities (Continued)

(a) Foreign currency risk management (Continued)

These collars establish a price ceiling and a price floor for the associated exchange rates. If the exchange rate falls below the floor, the counterparties will pay the Company the difference between the spot rate at the maturity date and the floor, calculated based on the notional amount of the contracts. Conversely, if the exchange rate increases above the ceiling, the Company will pay the counterparties the difference between the spot rate at the maturity date and the ceiling, calculated based on the notional amount of the contracts on the notional amount. The maturity dates of the derivatives contracts coincide with the maturity dates of each of the notes.

The Yen zero cost collar contracts were settled on September 8, 2003, with a cash payment of US$68. One of the Euro zero cost collars was settled on December 31, 2004, with a cash receipt of US$18.

The call option component of the Company’s zero cost foreign exchange collars at December 31, 2006 had a fair value of US$21 (US$12 at December 31, 2005) and the put option components a fair value of zero at December 31, 2006 (US$(1) at December 31, 2005).

(b) Commodity price risk management

Petroleum and oil products

The Company is exposed to commodity price risks as a result of the fluctuation of crude oil and oil product prices. The Company’s commodity risk management activities are primarily undertaking through the uses of future contracts traded on stock exchanges; and options and swaps entered into with major financial institutions. The futures contracts provide economic hedges for anticipated crude oil purchases and sales, generally forecasted to occur within a 30 to 360 day period, and reduce the Company’s exposure to volatility of such prices.

The Company's exposure from these contracts is limited to the difference between the contract value and market value on the volumes contracted. Crude oil future contracts are marked-to-market and related gains and losses are recognized in currently period earnings, irrespective of when the physical crude sales occur. For the years ended December 31, 2006, 2005 and 2004, the Company entered into commodity derivative transactions for 26.42%, 26.79% and 33.06%, respectively, of its total import and export trade volumes.

(b) Commodity price risk management (Continued)

The open positions in the futures market, compared to spot market values, resulted in recognized losses of US$2, US$1 and US$2 for the years ended December 31, 2006, 2005 and 2004, respectively.

A long-term position was opened in January 2001 via the sale of put options for 52 million barrels of West Texas Intermediate (WTI) oil, over a period extending from 2004 to 2007, with the objective of obtaining price protection for this quantity of oil and to provide the funding institutions of the Barracuda/Caratinga project with a minimum guaranteed margin to cover the debt servicing. The put options were structured to ensure that the financial institutions participating in the financing of the development of the fields receive the price required to generate the minimum required return on investment. The Company accounts for the put options on a mark to market basis. During 2006, 2005 and 2004 the Company realized no gain or loss.

(c) Interest rate risk management

The Company’s interest rate risk is a function of the Company’s long-term debt and to a lesser extent, its short-term debt. The Company’s foreign currency floating rate debt is principally subject to fluctuations in LIBOR and the Company’s floating rate debt denominated in Reais is principally subject to fluctuations in the Brazilian long-term interest rate (TJLP) as fixed by the National Monetary Counsel. The Company currently does not utilize derivative financial instruments to manage its exposure to fluctuations in interest rates. However, the Company will consider assessing the use of various types of derivatives to reduce its exposure to interest rate fluctuations and may use such financial instruments in the future.

(d) Risk Management activity at PEPSA

PEPSA uses derivative instruments such as options, swaps and others, mainly to mitigate the risk of changes in crude oil prices, interest rates and foreign exchange rates. Such derivative instruments are designed to mitigate specific exposures, and when designated as accounting hedges are assessed periodically to assure high correlation of the derivative instrument to the hedged risk exposure identified and to ensure that the derivative is highly effective in achieving offsetting changes in the cash flows of the hedged risk. PEPSA in the past designated certain relationships as accounting hedges for its crude oil derivative instruments and its interest rate swaps derivative instruments, but holds no such instruments at December 31, 2006; nor are any implemented accounting hedges outstanding.

As of December 31, 2006, PEPSA did not have commodity derivative transactions that qualify for hedge accounting purposes in accordance with SFAS No. 133 – Accounting for Derivative Instruments and Hedging Activities ("SFAS 133"). PEPSA accounted for a loss of US$103 for the year ended December 31, 2005 due to derivative financial instruments that did not qualify for hedge accounting.

At December 31, 2006, PEPSA had forward sales of US dollars in exchange for Argentine pesos. During the current fiscal year, the Company recognized a US$2 gain. As of December 31, 2006 and 2005 the face value of effective contracts amounts to US$18 and US$52, respectively, at the average exchange rate of 3.26 and 3 Argentine pesos per US dollar, respectively. Without considering the above-mentioned operations, as of December 31, 2006, the Company did not have any other positions in derivatives instruments.

(e) Cash flow hedge

In September, 2006 PIFCo entered into cross currency swap under which it swaps principal and interest payments on Yen denominated bonds for U.S. dollar amounts. Under U.S. GAAP, foreign currency cash flow hedges can only be designated as such when hedging the risk to the entity’s functional currency, and therefore, this cross currency swaps is qualified for hedge accounting designation take into account that PIFCo’s functional currency is the US dollar, and the assessment of hedge effectiveness indicates that the change in fair value of the designated hedging instrument is highly effective.

(e) Cash flow hedge (Continued)

The hedged item is ¥ 35 billion bond, ten-year maturity, carrying a semi-annual coupon of 2.15% p.a. The hedge instrument is a cross currency swap, ten year maturity, under which US dollars is paid and Japanese Yen is received mirroring the Yen bond conditions. The effectiveness test was made at the inception at the hedge based on the hypothetical derivative method. The effectiveness test will be made on an ongoing basis on a quarterly basis.

The transaction gain or loss arising from the remeasurement of Yen denominated bonds is offset by the reclassification relating to the remeasurement of the hedged item at spot rates from other comprehensive income to earnings. The cross currency swap at December 31, 2006 had a fair value of (US$9) due to the devaluation of the Japanese Yen when compared to US dollar since the inception of the instrument.

21. Natural Gas Derivative Contract

In connection with the long-term contract to buy gas (“The Gas Supply Agreement” or "GSA") to supply thermoelectric plants and for other uses in Brazil, the Company entered into a contract, with the company Empresa Petrolera ANDINA, a gas producer in Bolivia, that constituted a derivative financial instrument under SFAS 133. This contract, the Natural Gas Price Volatility Reduction Contract (the "PVRC"), was executed with the purpose of reducing the effects of price volatility under the GSA.

The terms of the PVRC provided for a price collar for the period from 2005 to 2019, with the Company receiving cash payments when the calculated price is above the established ceiling, and the Company making cash payments when the price is below the established floor, with no cash payments being made when the price is between the ceiling and the floor.

As of December 31, 2005, the Company recorded an asset based on the fair value of the derivative in the amount of US$547 and a liability of US$144, which was deemed a deferred purchase incentive.

Due to the new Hydrocarbons Law of Bolivia (see Note 9(b)), the other party to the PVRC contested the contract, alleging among others, “force majeure” and excessive onus. On August 12, 2006, the parties agreed to cancel the PVRC. As a result, on August 14, 2006 the Company received US$41 and wrote-off accounts receivable related to the PVRC amounting to US$77.

21. Natural Gas Derivative Contract (Continued)

The Company adjusted the fair value asset and liabilities related to the PVRC by recording a financial expense of US$328 during the first quarter of 2006 as a result of the tax increases in Bolivia. In the second quarter of 2006, the Company wrote-off the remaining fair value asset of US$94 as a consequence of the cancellation of contract.

22. Financial Instruments

In the normal course of its business activities, the Company acquires various types of financial instruments.

(a) Concentrations of credit risk

Substantial portions of the Company’s assets including financial instruments are located in Brazil while substantially all of the Company’s revenues and net income are generated in Brazil. The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of its cash and cash equivalents, government securities, the Petroleum and Alcohol account, trade receivables and futures contracts.

The Company takes several measures to reduce its credit risk to acceptable levels. All cash and cash equivalents in Brazil are maintained with major banks. Time deposits in U.S. dollars are placed with creditworthy institutions in the United States. Additionally, all of the Company’s available-for-sale securities and derivative contracts are either exchange traded or maintained with creditworthy financial institutions. The Company monitors its credit risk associated with trade receivables by routinely assessing the creditworthiness of its customers. At December 31, 2006 and December 31, 2005, the Company’s trade receivables were primarily maintained with large distributors.

(b) Fair value

Fair values are derived either from quoted market prices where available, or, in their absence, the present value of expected cash flows. Fair values reflect the cash that would have been either received or paid if the instruments were settled at year end in an arms length transaction between willing parties. Fair values of cash and cash equivalents, trade receivables, the Petroleum and Alcohol account, short-term debt and trade payables approximate their carrying values. The fair value for the Company’s available-for-sale government securities equals their carrying value.

(b) Fair value (Continued)

The fair values of other long-term receivables and payables do not differ materially from their carrying values.

The Company’s debt including project financing obligations, resulting from FIN 46(R) consolidation amounted to US$14,702 at December 31, 2006 and US$15,132 at December 31, 2005 and had estimated fair values of US$13,984 and U$15,239, respectively.

(1) In 2005 revenues from commercialization of oil to third parties are being classified in accordance with the points of sale, which could be Exploration & Production or Supply segments. Until 2004, revenues from commercialization of oil were completely allocated to Exploration & Production. This classification generated no significant impact on the results reported for these segments and segments information has not been restated as it is impractical to gather and collect data for prior periods as to point of sale.
(2) In order to align the financial statements of each business segment with the best practices of companies in the Oil & Gas sector and to improve the understanding of Petrobras’ management, the Company, since the first quarter of 2006, switched to allocating all financial results and items of financial nature to the corporate level.

25. Accounting for Suspended Exploratory Wells

The Company’s accounting for exploratory drilling costs is governed by Statement of Financial Accounting Standards No. 19, “Financial Accounting and Reporting by Oil and Gas Producing Companies” (SFAS No. 19). On April 4, 2005, the Financial Accounting Standards Board (FASB) issued FASB Staff Position (FSP FAS 19-1) that amended SFAS No. 19 with respect to the deferral of exploratory drilling costs. The Company adopted FASB Staff Position FAS 19-1) “Accounting forSuspended Wells Costs” effective from January 1, 2005. There was no material impact at adoption.

25. Accounting for Suspended Exploratory Wells (Continued)

Costs the Company has incurred to drill exploratory wells that find commercial quantities of oil and gas are carried as assets on its balance sheet under the classification “Property, plant and equipment” as unproved oil and gas properties. Each year, the Company writes off the costs of these wells that have not found sufficient proved reserves to justify completion as a producing well, unless (1) the well is in an area requiring major capital expenditure before production can begin and (2) additional exploratory drilling is under way or firmly planned to determine whether the capital expenditure is justified.

As of December 31, 2006, the total amount of unproved oil and gas properties was US$2,054, and of that amount US$321 (US$195 of which related to projects in Brazil) represented costs that had been capitalized for more than one year, which generally are a result of (1) extended exploratory activities associated with offshore production and (2) the transitory effects of deregulation in the Brazilian oil and gas industry, as described below.

In 1998, the Company’s government-granted monopoly ended and the Company signed concession contracts with the Agência Nacional de Petróleo (National Petroleum Agency, or ANP) for all of the areas the Company had been exploring and developing prior to 1998, which consisted of 397 concession blocks. Since 1998, the ANP has conducted competitive bidding rounds for exploration rights, which has allowed the Company to acquire additional concession blocks. After a concession block is found to contain a successful exploratory well, we must submit an “Evaluation Plan” to the ANP for approval. This Evaluation Plan details the drilling plans for additional exploratory wells. An Evaluation Plan is only submitted for those concession areas where technical and economic feasibility analyses on existing exploration wells evidence justification for completion of such wells. Until the ANP approves the Evaluation Plan, the drilling of additional exploratory wells cannot commence. If companies do not find commercial quantities of oil and gas within a specific time period, generally 4-6 years depending on the characteristics of the exploration area, then the concession block must be relinquished and returned to the ANP. Because the Company was required to assess a large volume of concession blocks in a limited time frame even when an exploratory well has found sufficient reserves to justify completion and additional wells are firmly planned, finite resources and expiring time frames in other concession blocks have dictated the timing of the planned additional drilling.

Of the US$321 for 50 projects that include wells suspended for more than one year since the completion of drilling, approximately US$103 are related to wells in areas for which drilling was under way or firmly planed for the near future and that we have submitted an “Evaluation Plan” to the ANP for approval and approximately US$54 incurred in costs for activities necessary to assess the reserves and their potential development.

The US321 of suspended well cost capitalized for a period greater than one year as of December 31, 2006 represents 66 exploratory wells and the table below contains the aging of these costs on a well basis:

26. Subsequent Events

(a) Global Notes

On January 4, 2007, PIFCo, a wholly owned subsidiary of Petrobras, announced an offer for the exchange of securities (Exchange Offering) totaling up US$500 (face value) for the five series of notes.

The objective of the Exchange was offer to the investors the opportunity to substitute the five old notes listed below, with PIFCo’s new benchmark issued on October 06, 2006, with a coupon of 6.125% per annum and maturity in 2016.

The settlement of the Exchange Offering occurred on February 7, 2007 and as a result, PIFCo received and accepted a tender amount of US$399 (face value of the Notes). All the notes received were cancelled in the same day and as a consequence, PIFCo issued US$399 of Global Notes due 2016 that bear interest at the rate of 6.125% per annun, payable semi-annually. The new Notes constitute a single, fungible series with the US$500 Global Notes due 2016 and issued on October 06, 2006, amounting to US$899 in securities issued with maturity in 2016. PIFCo also paid to the investors a cash amount equivalent to US$56 as a result of the Exchange. The table below presents the result of the Exchange.

(b) Leasing of the Araucária Gas Thermoelectric Power Station

Petrobras announced on January 3, 2007 that it had executed two service provision and leasing contracts with UEG Araucária and COPEL. The first contract refers to the leasing of the Araucária Gas Thermoelectric Power Station executed by Petrobras and UEG, in force until December 31, 2007 which may be extended for a period of up to 12 months. The second contract involves the provision of maintenance and operating services regarding the UEG Araucária, executed by Petrobras and COPEL Geração, in force until December 31, 2008 or the end of the leasing agreement, whichever occurs first.

Under the two contracts, a fixed monthly payment will be due of US$8.89 per MWh multiplied by the reference voltage (428,35 MW) plus a variable monthly payment of US$15.54 per MWh, on the effective energy generated. These proceeds are used to cover all costs and taxes incurred by UEG.

Executing these contracts will enable better allocation of the gas produced to meet the fundamental commitments referring to the energy sold by the Company.

(c) Repactuation of PETROS Plan

During 2006 Petrobras presented to employee participants and retirees a proposal to bring equilibrium to the actual PETROS Plan. On February 28, 2007 the target for the minimum accession number to the renegotiation set at 2/3 (two-thirds) of the members and was met (see Note 16 (b)).

The renegotiation process consists of changing the plan’s regulation, particularly the articles related to how the benefits are readjusted, disentailing the readjustment of the benefits paid to retirees and pensioners from wage increases granted to active employees and INSS retirees. Petros Plan benefits, disentailed from the active employees wage and INSS retirement and pension plan readjustments, will be adjusted based on the IPCA (cost of living index).

(c) Repactuation of PETROS Plan (Continued)

The financial incentive to be granted to the participants, whether employees or retirees, as negotiated by the labor union representatives as a counterpart for the Plan’s repactuation, amounted to US$425 and was paid on March 2007.

The proposal’s approval also opens the way to reach agreements with Labor Union Representations in order to liquidate and extinguish legal suits, particularly the Public Civil Suit regarding Petrobras System’s complementary retirement issues. The demands that refer to the items to be removed from the lawsuits will be attended to through the calculation of their actuarial value and paid for by Petrobras, in 20 years, respecting the Plan’s liquidity conditions.

(d) Ipiranga Group Acquisition

On March 19, 2007, Ultrapar Participações S.A. ("Ultrapar") has celebrated, with the acknowledgement of Petróleo Brasileiro S.A. ("Petrobras") and Braskem S.A.("Braskem") a contract with the controlling shareholders of Refinaria de Petróleo Ipiranga S.A, Distribuidora de Produtos de Petróleo Ipiranga S.A. and Companhia Brasileira de Petróleo Ipiranga for the acquisition of their total interest in those companies, including petrochemical and distribution assets.

After the completion of the acquisition, the businesses of the Ipiranga Group will be managed by Ultrapar, Petrobras and Braskem. Ultrapar will hold 100% interest of the oil products and lubricant distribution businesses located in the South and Southeast regions of Brazil, Petrobras will hold 100% interest of the oil products and lubricant distribution businesses located in the North, Northeast and Central West regions of Brazil. Petrobras and Braskem will hold the petrochemical assets in the proportion of 60% and 40% respectively. The assets related to refining operations will be equally shared between Petrobras, Ultrapar and Braskem.

The conclusion of operation is estimated to occur during the fourth quarter of 2007. The transaction will occur in some fases including acquisitions and incorporation of shares, delisting of public companies in Brazilian Stock Exchange and segregation of the distribution and petrochemical assets.

The total value estimated for the operation is US$4.0 billion and Petrobras will pay approximately US$1.3 billion for its interest. The transaction will be presented for appreciation of the Brazilian Anti-trust Authorities (CADE – Administrative Board for Economic Defense), the Secretary for Economic Rights and the Secretary for Economic Monitoring.

SUPPLEMENTARY INFORMATION ON OIL AND GAS EXPLORATION AND 
PRODUCTION ACTIVITIES (UNAUDITED)
Expressed in Millions of United States Dollars 
(except when specifically indicated)
 

In accordance with SFAS 69 - Disclosures About Oil and Gas Producing Activities ("SFAS 69"), this section provides supplemental information on oil and gas exploration and producing activities of the Company. The information included in items (i) through (iii) provides historical cost information pertaining to costs incurred in exploration, property acquisitions and development, capitalized costs and results of operations. The information included in items (iv) and (v) present information on Petrobras’ estimated net proved reserve quantities, standardized measure of estimated discounted future net cash flows related to proved reserves, and changes in estimated discounted future net cash flows.

Beginning in 1995, the Federal Government of Brazil undertook a comprehensive reform of the country’s oil and gas regulatory system. On November 9, 1995, the Brazilian Constitution was amended to authorize the Federal Government to contract with any state or privately-owned company to carry out the activities related to the upstream and downstream segments of the Brazilian oil and gas sector. This amendment eliminated Petrobras’ effective monopoly. The amendment was implemented by the Petroleum Law, which liberated the fuel market in Brazil beginning January 1, 2002.

The Petroleum Law established a new regulatory framework ending Petrobras’ exclusive agency and enabling competition in all aspects of the oil and gas industry in Brazil. As provided in the Petroleum Law, Petrobras was granted the exclusive right for a period of 27 years to exploit the petroleum reserves in all fields where the Company had previously commenced production. However, the Petroleum Law established a procedural framework for Petrobras to claim exclusive exploratory (and, in case of success, development) rights for a period of up to three years with respect to areas where the Company could demonstrate that it had "established prospects". To perfect its claim to explore and develop these areas, the Company had to demonstrate that it had the requisite financial capacity to carry out these activities, alone or through financing or partnering arrangements.

The "International" geographic includes activities in Angola, Argentina, Bolivia, Colombia, Ecuador, Mexico, Nigeria, Peru, the United States of America, Venezuela, Iran, Lybia and Tanzania. The Company has immaterial non-consolidated companies involved in exploration and production activities; the amounts related to such are in the line item titled “Company’s share of unconsolidated affiliates”.

(iii) Results of operations for oil and gas producing activities

The Company’s results of operations from oil and gas producing activities for the years ending December 31, 2006, 2005 and 2004 are shown in the following table. The Company transfers substantially all of its Brazilian crude oil and gas production to the supply segment in Brazil. The prices calculated by the Company’s model may not be indicative of the price the Company would have realized had this production been sold in an unregulated spot market. Additionally, the prices calculated by the Company’s model may not be indicative of the future prices to be realized by the Company after January 1, 2002, when full price deregulation began. Gas prices used are contracted prices to third parties.

Production costs are lifting costs incurred to operate and maintain productive wells and related equipment and facilities, including such costs as operating labor, materials, supplies, fuel consumed in operations and the costs of operating natural liquid gas plants. Production costs also include administrative expenses and depreciation and amortization of equipment associated with production activities.

Exploration expenses include the costs of geological and geophysical activities and non-productive exploratory wells. Depreciation and amortization expenses relate to assets employed in exploration and development activities. In accordance with SFAS 69, income taxes are based on statutory tax rates, reflecting allowable deductions. Interest income and expense are excluded from the results reported in this table.

(iv) Reserve quantities information

The Company’s estimated net proved oil and gas reserves and changes thereto for the years 2006, 2005 and 2004 are shown in the following table. Proved reserves are estimated by the Company’s reservoir engineers in accordance with the reserve definitions prescribed by the Securities and Exchange Commission.

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. Proved reserves do not include additional quantities recoverable beyond the term of the concession or contract, or that may result from extensions of currently proved areas, or from application of secondary or tertiary recovery processes not yet tested and determined to be economic.

Proved developed reserves are the quantities expected to be recovered from existing wells with existing equipment and operating methods. Proved undeveloped reserves are those volumes which are expected to be recovered as a result of future investments in drilling, re-equipping existing wells and installing facilities necessary to deliver the production from these reserves.

In some cases, substantial new investments in additional wells and related facilities will be required to recover these proved reserves. Due to the inherent uncertainties and the limited nature of reservoir data, estimates of reserves are subject to change as additional information becomes available.

(iv) Reserve quantities information (Continued)

The decrease in reserves is related to revisions of previous estimates due to Bolivia and Venezuela new nationalization measures during 2006. The new regulation in Venezuela reduced our reserves as PDVSA became the main controller of the companies created to operate the fields with private companies. In Bolivia, due to new government regulations, occurred a decrease in the reserves. In Nigeria, the consortium in charge of Akpo field was constituted by Total, Petrobras and a Nigerian private company called SAPETRO. The agreement underwritten by these companies established that TOTAL and Petrobras carried the investment cost of the third part and it would be compensated in the future with SAPETRO’s production/reserves.

Along 2006, SAPETRO sold its participation to a Chinese oil company and, as part of this agreement, Petrobras and TOTAL were reimbursed for their past carrying investments

(v) Standardized measure of discounted future net cash flows relating to proved oil and gas quantities and changes therein

The standardized measure of discounted future net cash flows, related to the above proved oil and gas reserves, is calculated in accordance with the requirements of SFAS 69. Estimated future cash inflows from production in Brazil are computed by applying year-end prices based upon the Company’s internal pricing methodology for oil and gas to year-end quantities of estimated net proved reserves. Estimated future cash inflows from production related to the Company’s International segment are computed by applying year-end prices for oil and gas to year-end quantities of estimated net proved reserves. Future price changes are limited to those provided by contractual arrangements in existence at the end of each reporting year. Future development and production costs are those estimated future expenditures necessary to develop and produce year-end estimated proved reserves based on year-end cost indicators, assuming continuation of year-end economic conditions. Estimated future income taxes are calculated by applying appropriate year-end statutory tax rates. These rates reflect allowable deductions and are applied to estimated future pre-tax net cash flows, less the tax basis of related assets. Discounted future net cash flows are calculated using 10% midperiod discount factors. This discounting requires a year-by-year estimate of when the future expenditures will be incurred and when the reserves will be produced.

The information provided does not represent management’s estimate of Petrobras’ expected future cash flows or value of proved oil and gas reserves. Estimates of proved reserve quantities involves uncertainty and change over time as new information becomes available. Moreover, probable and possible reserves, which may become proved in the future, are excluded from the calculations.

(v) Standardized measure of discounted future net cash flows relating to proved oil and gas quantities and changes therein (Continued)

The arbitrary valuation prescribed under SFAS 69 requires assumptions as to the timing and amount of future development and production costs. The calculations are made as of December 31 each year and should not be relied upon as an indication of Petrobras’ future cash flows or the value of its oil and gas reserves.
