2Basis of presentation

2.1Accounting practices

The accompanying condensed consolidated financial information has been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”), which differ in certain aspects from the accounting practices adopted in Brazil (“Brazilian GAAP”) applied by the Company in the preparation of its legal financial statements. In accordance with Brazilian Securities and Exchange Commission (CVM) rules, the Company has started to present its consolidated financial statements under IFRS (International Financial Reporting Standards) beginning the third quarter of 2007. The consolidated financial statements under IFRS are prepared in Brazilian reais.

The condensed consolidated financial information as of and for the three-month and nine-month periods ended September 30, 2008 and 2007 are unaudited. However, in the opinion of management, this financial information includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the consolidated financial position, results of operations and cash flows for the interim periods presented. The results for the three-month and nine-month periods ended September 30, 2008 are not necessarily indicative of the results to be expected for the entire year.

This condensed financial information has been prepared on substantially the same basis as the consolidated financial statements as of and for the year ended December 31, 2007, except for the recognition of a qualifying cash flow hedge and a net investment hedge (Note 9), and should be read in conjunction therewith.

The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

2.2Recently issued accounting standards

In December 2007, the FASB issued Statement of Financial Accounting Standards No. 141 (revised 2007) “Business Combinations” (“SFAS 141R”). SFAS 141R replaces FASB Statement No. 141, “Business Combinations,” (“SFAS 141”).  SFAS 141R establishes the requirements for how an acquirer recognizes and measures the identifiable assets acquired, the liabilities assumed, any non-controlling interest in the acquired and the goodwill acquired. SFAS 141R also establishes disclosure requirements for business combinations. SFAS 141R applies to business combinations for which the acquisition date is on or after December 15, 2008. For business combinations in which the acquisition date was before the effective date of this Statement, the acquirer shall apply the requirements of Statement 109, as amended by this Statement, prospectively. That is, the acquirer shall not adjust the accounting for prior business combinations for previously recognized changes in acquired tax uncertainties or previously recognized changes in the valuation allowance for acquired deferred tax assets. However, after the effective date of this Statement. The Company is evaluating the potential impact on its consolidated financial statements upon adoption of SFAS 141R.

In December 2007, the FASB issued SFAS No. 160 “Non-controlling Interests in Consolidated Financial Statements — an amendment to ARB No. 51” (“SFAS 160”). SFAS 160 establishes accounting and reporting for minority interests, now termed “non-controlling interests”. SFAS 160 requires non-controlling interests to be presented as a separate component of equity and requires the amount of net income attributable to the parent and to the non-controlling interest to be separately identified on the consolidated statement of income. SFAS 160 is effective for fiscal years beginning on or after December 15, 2008. The Company is evaluating the potential impact on its consolidated financial statements upon adoption of SFAS 160.

In March 2008, the FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities—an amendment of FASB Statement No. 133” (Statement 161).  SFAS 161 requires entities that utilize derivative instruments to provide qualitative disclosures about their objectives and strategies for using such instruments, as well as any details of credit-risk-related contingent features contained within derivatives. SFAS 161 also requires entities to disclose additional information about the amounts and location of derivatives located within the financial statements, how the provisions of SFAS 133 has been applied, and the impact that hedges have on an entity’s financial position, financial performance, and cash flows. SFAS 161 is effective for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged.  The Company is evaluating the potential impact on its consolidated statements upon adoption of Statement 161.

In April 2008, the FASB issued FSP 142-3, “Determination of the Useful Life of Intangible Assets”, (“FSP 142-3”). FSP 142-3 amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset under SFAS No. 142, “Goodwill and Other Intangible Assets”. FSP 142-3 is effective for fiscal years beginning after December 15, 2008. The Company is evaluating the potential impact of FSP 142-3 on its consolidated financial statements.

In May 2008, the FASB issued SFAS No. 162 “The Hierarchy of Generally Accepted Accounting Principles”. SFAS 162 identifies the sources of accounting principles and the framework for selecting the principles to be used in the preparation of financial statements. SFAS 162 is effective 60 days following the SEC´s approval of the Public Company Accounting Oversight Board amendments to AU Section 411, “The Meaning of Present Fairly in Conformity with Generally Accepted Accounting Principles”. The Company does not expect to have any significant impact of adopting this SFAS.

In May 2008, the FASB issued SFAS No. 163 “Accounting for Financial Guarantee Insurance Contracts—an interpretation of FASB Statement No. 60”. SFAS 163 clarifies how FASB Statement No. 60, Accounting and Reporting by Insurance Enterprises, applies to financial guarantee insurance contracts issued by insurance enterprises, including the recognition and measurement of premium revenue and claim liabilities. It also requires expanded disclosures about financial guarantee insurance contracts. SFAS 163 is effective for fiscal

years and interim periods beginning after December 15, 2008. The Company does not expect to have any impact of adopting this SFAS.

In October 2008, the FASB issued FSP 157-3 “Determining Fair Value of a Financial Asset in a Market that is Not Active” (“FSP 157-3”). FSP 157-3 clarified the application of SFAS No. 157 in an inactive market. It demonstrated how the fair value of a financial asset is determined when the market for that financial asset is inactive. FSP 157-3 was effective upon issuance, including prior periods for which financial statements had not been issued. The implementation of this standard did not have a significant impact on Company’s consolidated financial statements consolidated.

2.3Adoption of new accounting standards

In September 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 157 “Fair Value Measurements” (“SFAS 157”).  SFAS 157 introduces a framework for measuring fair value and expands required disclosure about fair value measurements of assets and liabilities. SFAS 157 for financial assets and liabilities is effective for fiscal years beginning after November 15, 2007, and the Company has adopted the standard for those assets and liabilities as of January 1, 2008. The adoption of SFAS 157 did not materially impact the Company balance sheet, statement of income, or cash flow. The Company is now required to provide additional disclosures as a part of its consolidated financial statements.

In February 2008, the FASB issued Staff Position (“FSP”) 157-2, “Effective Date of FASB Statement No. 157”. This FSP delays the effective date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value on a recurring basis (at least annually) to fiscal years beginning after November 15, 2008, and interim periods within those fiscal years. The Company is currently assessing the impact of SFAS No. 157 for nonfinancial assets and nonfinancial liabilities on its consolidated balance sheets and statements of income.

SFAS 157 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. SFAS 157 also establishes a three – tier fair value hierarchy which prioritizes the inputs in measuring fair value requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than Level 1 prices such as quoted prices (unadjusted) for similar assets or liabilities; quoted prices (unadjusted) in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

As of September 30, 2008, the Company held certain assets that are required to be measured at fair value on a recurring basis. These assets included investments in private securities and derivative instruments.

The private securities refer to investment funds and stocks that were classified as Level 1 and fixed-income investments (Bank Deposit Certificate – “CDB” and Interbank Deposit – “DI”) that were classified as Level 2. The Company’s derivative instruments consist of interest rate swaps and collar contracts which are traded on a public exchange. See Note 9 for further information on the Company’s derivative instruments and hedging

activities. The fair values of the derivatives were determined based on inputs that are readily available in public markets or derived from information available in publicly quoted markets. Therefore, the Company utilized level 2 inputs to measure the fair market value of these derivatives. The Company utilized a standard pricing model based on inputs that were either readily available in public markets, derived from information available in publicly quoted markets, or quoted by counterparties to these contracts to determine the value of the derivatives. The Company has consistently applied these valuation techniques in all periods presented and believes it has obtained the most accurate information available for the types of derivative contracts it holds.

The Company also held auction rate securities instruments with a fair market value of $47.2 million. Over the past several months, auctions for certain auction rate securities failed because sell orders have exceeded buy orders. As a result of these failed auctions or future failed auctions, the Company may not be able to liquidate these securities until a future auction is successful, the issuer redeems the outstanding securities or the securities mature. Although it is the Company’s intention to sell these investments when liquidity returns to the market for these securities, during the three months ended June 30, 2008, the Company reclassified the investments from a current asset to a non-current asset. Due to the lack of availability of observable market quotes on the Company’s investment portfolio of auction rate securities, the Company utilizes valuation models including those that are based on expected cash flow schemes and collateral values, including assessments of counterparty credit quality, default risk underlying the security, discount rates and overall capital market liquidity in a non-active market as of September 30, 2008. Therefore, the Company utilized level 3 inputs to measure the fair market value of these investments.

The Company’s financial assets and liabilities measured at fair value on a recurring basis subject to the disclosure requirements of SFAS 157 at September 30, 2008, were as follows:

	Fair Value Measurements at Reporting Date Using

In February 2007, the FASB issued Statement No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”). The standard provides companies with an option to report selected financial assets and liabilities at fair value and establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar types of assets and liabilities. The Company did not elect the fair value option for any financial assets or financial liabilities as of January 1, 2008, the effective date of the standard.

2.4Currency translation

The Company has selected the United States dollar as its reporting currency. The U.S. dollar amounts have been translated following the criteria established in SFAS No. 52, “Foreign Currency Translation” from the financial statements expressed in the local currency of the countries where Gerdau and each subsidiary operates.

The Company’s main operations are located in Brazil, the United States, Canada, Spain and Chile. The local currency is the functional currency for those operations. These financial statements, except for those of the subsidiaries located in the United States which already prepare their financial statements in U.S. dollars, are translated from the functional currency into the U.S. dollar. Assets and liabilities are translated at the exchange rate in effect at the end of each period. Average exchange rates are used for the translation of revenues, expenses, gains and losses in the statement of income. Capital contributions, treasury stock transactions and dividends are translated using the exchange rate as of the date of the transaction. Translation gains and losses resulting from the translation methodology described above are recorded directly in “Cumulative other comprehensive loss” within shareholders’ equity. Gains and losses on foreign currency denominated transactions are included in the consolidated statement of income.

2.5Controlling shareholder

As of September 30, 2008, the Company’s parent, Metalúrgica Gerdau S.A. (“MG”, collectively with its subsidiaries and affiliates, the “Conglomerate”) owned 45.51% (December 31, 2007 and September 30, 2007 — 44.86% and 44.53% respectively) of the total capital of the Company. MG’s share ownership consisted of 76.45% (December 31, 2007 and September 30, 2007 — 74.89% and 74.94% respectively) of the Company’s voting common shares and 28.97% (December 31, 2007 and September 30, 2007 — 28.71% and 28.38% respectively) of its non-voting preferred shares.

compensation plans. The Company accounts for the stock-based compensation plans as from January 1, 2006 under SFAS 123 — R (“SFAS 123R”) “Shared-based payment”. SFAS 123R addresses the accounting for employee stock options and eliminates the alternative use of the intrinsic value method of accounting that was provided in Statement 123 as originally issued.  This statement requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments, based on the grant-date fair value of the award. That cost will be recognized over the period during which an employee is required to provide services in exchange for the award (vesting period). The grant-date fair value of employee share options and similar instruments is estimated using option-pricing models adjusted to the unique characteristics of those instruments.

The Company applied the modified prospective application method to account for the implementation of SFAS 123R, which consists recognizing costs of services rendered as from January 1, 2006 according to the grant-date fair value of stock options instruments, but does not require to restate previous year financial statements, and instead requires pro forma disclosures of net income and earnings per share for the effects on compensation had the grant-date fair value been adopted in prior periods. Under this transition method, compensation cost for stock options plans as from January 1, 2006, include the applicable amount of: (a) compensation cost for all share based instruments granted prior to, but not yet vested, as of January 1, 2006 (based on the grant-date fair value in accordance with the provisions of SFAS 123), and (b) compensation cost for all share based instruments granted after January 1, 2006 (based on the grant-date fair value estimated in accordance with the new provisions of SFAS 123R).

Through December 31, 2005, the Company applied the intrinsic value method established by Accounting Principles Board (“APB”) Opinion Nº 25, “Accounting for Stock Issued to Employees” to account compensation for stock based compensation.

The Company and its subsidiary Gerdau Ameristeel have several stock based compensation plans. A brief summary of those plans is presented below:

Gerdau Plan

The Extraordinary Stockholders’ General Meeting of Gerdau held on April 30, 2003 decided, based on a plan approved by an Annual Stockholders’ meeting and up to the limit of authorized capital, to grant options to purchase shares to management, employees or individuals who render services to the Company or to entities under its control, and approved the creation of the “Long Term Incentive Program”. Under the plan, the Board of Directors may grant options to purchase shares at an exercise price established by the Board of Directors and that can be exercised after a vesting period and up to 5 years after vested.

During the three-month and nine-month periods ended September 30, 2008, the Company recognized $1,317 and $3,369, respectively (September 30, 2007 - $935 and $2,175, respectively) of stock compensation costs related to the options issued during 2007. At September 30, 2008, the remaining unrecognized compensation cost related to these unvested options was approximately $11,620 (September 30, 2007 - $9,422) and the weighted-average period of time over which this cost will be recognized is 3.04 years (September 30, 2007 -3.15 years).

Gerdau Ameristeel Plans

Gerdau Ameristeel has several stock based compensation plans, which are described below.

The long-term incentive plans are designed to reward the Company’s senior management with bonuses based on the achievement of return on capital invested targets.  Bonuses which have been earned are awarded after the end of the year in the form of cash, stock appreciation rights (“SARs”), and/or options. The portion of any bonus which is payable in cash is to be paid in the form of phantom stock. The number of shares of phantom stock awarded to a participant is determined by dividing the cash bonus amount by the fair market value of a Common Share at the date the award of phantom stock is made. Phantom stock and SARs vest 25% on each of

F-14

GERDAU S.A.

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL INFORMATION (Unaudited)

(in thousands of U.S. Dollars, unless otherwise stated)

the first four anniversaries of the date of the award. Phantom stock will be paid out following vesting in the form of a cash payment. The number of options or SARs awarded to a participant is determined by dividing the non-cash amount of the bonus by the fair market value of the option or SAR at the date the award of the options or SARs is made. The value of the options or SARs is determined by the Human Resources Committee of the Company’s Board of Directors based on a Black-Scholes or other method for determining option values. Options vest 25% on each of the first four anniversaries of the date of the award.  Options may be exercised following vesting. Options have a maximum term of 10 years. The maximum number of options able to be granted under this plan is 6,000,000.

An award of approximately $8.3 million was earned by participants in 2007 and was granted 44% in SARs, 28% in options and 28% in phantom stock.  On February 28, 2008, the Company issued 379,564 options, under this plan. These awards are being accrued over the vesting period.

The 2006 Stock Appreciation Rights Plan was designed to attract, retain, and motivate participating employees of the Company through awards of SARs. The SARs vest 25% on each of the first four anniversaries of the date of the award. SARs with a fair market value of approximately $0.3 million were provided to certain participants in 2008 under this plan.

During the nine months ended September 30, 2008 and 2007, the compensation costs recognized by the Company for options issued during 2007 and 2008 were insignificant. At September 30, 2008, the remaining unrecognized compensation cost related to all unvested options was approximately $1.9 million and the weighted-average period of time over which this cost will be recognized is 2.8 years.

Methodology and assumptions used to estimate grant-date fair value

The Company has selected the Black-Scholes model to estimate the grant-date fair value of stock based compensation. Under SFAS 123R, the Company is required to estimate forfeitures when determining the stock based compensation expense as opposed to recognizing the forfeitures and the corresponding reduction in expense when they occur. The following weighted-average assumptions were used to estimate the compensation expense following the fair value method for compensation in stock of Gerdau S.A. and of Gerdau Ameristeel Corp., as appropriate.

Assumptions for options granted during the nine-month period ended September 30, 2008

2.9Derivative financial instruments

Derivative financial instruments that do not qualify for hedge accounting are recognized on the balance sheet at fair value with unrealized gains and losses recognized in the statement of income.

To qualify as a hedge, the derivative must be (i) designated as a hedge of a specific financial asset or liability at the inception of the contract, (ii) effective at reducing the risk associated with the exposure to be hedged, and (iii) highly correlated with respect to changes either in its fair value in relation to the fair value of the item being hedged or with respect to changes in the cash flows, both at inception and over the life of the contract.

As required by SFAS 133, “Accounting for Derivative Instruments and Hedging Activities,” as amended (“SFAS 133”) the Company assess both at the inception of each hedge and on an on-going basis, whether the derivatives that are used in its hedging transactions are highly effective in offsetting the changes in cash flows of the hedged item.

 (in thousands of U.S. Dollars, unless otherwise stated)

Long-term debt, excluding debentures, denominated in Brazilian reais

Long-term debt denominated in Brazilian reais is indexed for inflation using the TJLP (Taxa de Juros de Longo Prazo – “Long term interest rate”) rate set by the Government on a quarterly basis, or based on IGPM (Índice Geral de Preços – Mercado – “General Index Price – Market”).

Long-term debt, excluding debentures, denominated in foreign currencies

(a) Gerdau, Gerdau Açominas, Gerdau Aços Longos, Gerdau Aços Especiais, Gerdau Comercial de Aços and Aços Villares

The debt agreements entered into by the Company’s Brazilian subsidiaries contain covenants, which are described below, that require the maintenance of certain ratios, as calculated in accordance with the Company’s financial statements prepared in accordance with IFRS. The covenants include financial covenants including ratios on liquidity, total debt to EBITDA (earnings before interest, taxes, depreciation and amortization, as defined in the respective debt agreements), debt service coverage and interest coverage, amongst others. At September 30, 2008, the Company was in compliance with all of its debt covenants.

Guaranteed Perpetual Senior Securities

On September 15, 2005, Gerdau S.A. concluded a private placement of the $600,000 with 9.75% p.a. of interest bearing Guaranteed Perpetual Senior Securities. Such bonds are guaranteed by the following operating companies of Gerdau based in Brazil: Gerdau Açominas, Gerdau Aços Longos, Gerdau Aços Especiais and Gerdau Comercial de Aços. The bonds do not have a stated maturity date but should be redeemed by Gerdau S.A. in the event of certain specified events of default (as defined in the terms of the bonds) which are not fully under the control of the Company. The Company has a call option to redeem these bonds at any moment after 5 years of placement (September 2010). Interest payments are due on a quarterly basis, and each quarterly payment date is also a call date after September 2010.

Covenants

As a way of monitoring the financial condition of the Company, the banks involved in certain of the financing agreements use restrictive covenants, as described below:

I) Consolidated Interest Coverage Ratio - measures the debt service payment capacity in relation to EBITDA (Net Income before Interest, Taxes, Depreciation and Amortization)

II) Consolidated Leverage Ratio - measures the debt coverage capacity in relation to EBITDA (Net Income before Interest, Taxes, Depreciation and Amortization).

III) Required Minimum Net Worth - measures the minimum net worth required in financing agreements.

IV) Current Ratio (current liquidity ratio) - measures the capacity to pay current liabilities.

All the covenants mentioned above are calculated based on the Consolidated Financial Statements in IFRS of Gerdau S.A., except for item IV, which refers to Metalúrgica Gerdau S.A., and have been complied with. Pursuant to the agreements, the penalty for non-compliance with such covenants is the possibility of a default statement by the banks and acceleration of maturity of loans.

(b) Sipar Aceros, Diaco, Cleary Holdings,Sidelpa, Gerdau AZA, Siderperú, Siderúrgica Zuliana, Gerdau GTL Mexico and GTL Trade Finance Inc.

GERDAU S.A.

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL INFORMATION (Unaudited)

 (in thousands of U.S. Dollars, unless otherwise stated)

The subsidiary Siderperú has obtained a financing for working capital of $150,067, maturing in 2014 with a variable rate of Libor + 0.9% p.a.. Such proceeds were used to pay out the outstanding debt with suppliers and credits acquired by the Company by the time of the acquisition of this subsidiary.

Ten-Years Bonds

On October 22, 2007, the subsidiary GTL Trade Finance Inc. concluded the placement of Ten-Years Bonds in the amount of $1 billion. Such Bonds, which mature on October 20, 2017, are subject to interest of 7.25% p.a., payable semi-annually in the months of April and October, beginning April 2008, and guaranteed by Gerdau S.A., Gerdau Açominas S.A., Gerdau Aços Longos S.A., Gerdau Aços Especiais S.A., and Gerdau Comercial de Aços S.A. In May 2008 the Company concluded the reopening of the Bond with a maturity in 2017, through the subsidiary GTL Trade Finance Inc. in the amount of $500.0 million and a yield of 6.875% p.a.. The new issuance will be incorporated into the issuance made in October 2007 and will be subject to interest of 7.25% p.a., which will be paid every six months (in April and October). These funds will be used to repay the Bridge Loan of $1 billion that was taken by this subsidiary on April 16, 2008. The bonds are senior unsecured obligations of the Issuer, ranking equal in right of payment with all of the Issuer’s other existing and future senior unsecured debt. The guarantees of the bond will rank pari passu with all unsecured and unsubordinated obligations of each of the Guarantors.

The bonds and the guarantees of the bonds were not registered under the U.S. Securities Act of 1933, as amended, or the Securities Act, or under any state securities law. Therefore, the bonds were not offered or sold within the United States to, or for the account or benefit of, any U.S. person unless the offer or sale was qualified for a registration exemption from the Securities Act and applicable state securities laws. Accordingly, the bonds were offered and sold to qualified institutional buyers (as defined in Rule 144A under the Securities Act) and to non U.S. people outside the United States in compliance with Regulation S under the Securities Act.

(c) Long-term Debt of Gerdau Ameristeel

On June 27, 2003, Gerdau Ameristeel refinanced its debt by issuing $405.0 million aggregate principal 10 3/8% Senior Notes. The notes mature July 15, 2011 and were issued at 98% of face value.  Gerdau Ameristeel amortizes the bond discount using the straight line method, which is not materially different from the effective interest method.  Gerdau Ameristeel can call these Senior Notes at any time at a redemption price ranging from 105 3/8% to 100%, depending on the year the call is made. As a result of the Company having hedged a portion of its 10 3/8% Senior Notes and then subsequently terminating these hedges, the carrying value of those notes was adjusted to reflect the final fair value of the derivatives as of the time they were terminated. Gerdau Ameristeel amortizes this final fair value using the straight line method which approximates the effective yield method.

On October 31, 2005, Gerdau Ameristeel amended the Senior Secured Credit Facility, which provided commitments of up to $650.0 million and expires on October 31, 2010.  In June 2008, Gerdau Ameristeel increased the Senior Secured Credit Facility from $650.0 million to $950.0 million. The Company is in compliance with the terms of the facility at September 30, 2008.  The borrowings under the Senior Secured Credit Facility are secured by the Company’s inventory and accounts receivable.  At both September 30, 2008 and December 31, 2007, there was nothing drawn against this facility based upon available collateral under the terms of the agreement. At September 30, 2008 and December 31, 2007, approximately $873.7 million and $583.0 million, respectively, were available under the Senior Secured Credit Facility, net of $76.3 million and $67.0 million, respectively of outstanding letters of credit.

Gerdau Ameristeel had $50.4 million and $54.6 million of industrial revenue bonds outstanding at September 30, 2008 and December 31, 2007, respectively. In April 2008, Gerdau Ameristeel repaid the $4.2 million industrial revenue bond that was assumed with the acquisition of the Beaumont, Texas facility in November 2004. Approximately $23.8 million of the bonds were issued by Gerdau Ameristeel US Inc., a wholly owned subsidiary of the Company, in prior years to construct facilities in Jackson, Tennessee. The interest on the

The Jackson, Tennessee and Cartersville, Georgia bonds are secured by letters of credit issued under the Senior Secured Credit Facility. On May 3, 2007, Gerdau Ameristeel US Inc. entered into a new industrial revenue bond for the Jacksonville, Florida facility. The industrial revenue bond is for $23.0 million and matures on May 1, 2037. The interest on this bond is 5.3% payable semi-annually. This bond is secured by a guarantee by the Company.

On September 14, 2007, the Gerdau Ameristeel entered into a $2.75 billion Term Loan Facility to partially finance its acquisition of Chaparral of which $150.0 million of the Term Loan has been repaid.

The Term Loan Facility has tranches maturing between 5 and 6 years from the closing date and bearing interest at LIBOR plus between 1.00% and 1.25%. The Term Loan Facility is not secured by the assets of Gerdau Ameristeel or its subsidiaries. Gerdau S.A. and certain of its Brazilian affiliates have guaranteed the obligations of the borrowers. The Term Loan Facility includes financial covenants requiring Gerdau S.A. and its subsidiaries on a consolidated basis to satisfy maximum total debt to EBITDA and minimum EBITDA to interest expense tests, and the value of Gerdau S.A.’s and certain of its subsidiaries’ receivables under certain off-take supply contracts to at all times exceed the principal amount of the outstanding term loans. The Term Loan Facility is unsecured but provides for a springing lien in the off-take supply contracts.  The Term Loan Facility also contains customary covenants restricting the Company’s ability, including the ability of certain of its subsidiaries, including Gerdau Ameristeel US Inc. and GNA Partners, GP, to incur additional liens on such entities’ assets, enter into certain transactions with affiliates and enter into certain merger transactions.  The Company is in compliance with the terms of the Term Loan Facility.

6Commitments and contingencies

The Company is party to claims with respect to certain taxes, civil and labor matters. Management believes, based in part on advice from legal counsel, that the provision for contingencies is sufficient to meet probable and reasonably estimable losses from unfavorable rulings, and that the ultimate resolution will not have a significant effect on the consolidated financial position as of September 30, 2008, although it may have a significant effect on future results of operations or cash flows.

The following table summarizes the contingent claims and related judicial deposits:

	Contingencies			Judicial deposits
	September 30,		December	September 30,		December
Claims	2008	2007	31, 2007	2008	2007	31, 2007

Probable losses on tax matters, for which a provision was recorded

All contingencies described in the section below correspond to instances where the Company is challenging the legality of taxes and contributions. The description of the contingent losses includes a description of the tax or contribution being challenged, the current status of the litigations as well as the amount of the probable loss which has been provided as of September 30, 2008.

·Of the total provision, $17,216 relates to amounts of State Value Added Tax (“Imposto sobre Circulação de Mercadorias e Serviços” – ICMS), the majority of which relating to credit rights. Most of the proceedings under judgment by the Finance Department of the States of Mato Grosso, Maranhão, Amazonas, Bahia, Rio de Janeiro and Minas Gerais, by the State Courts of Pernambuco e Minas Gerais e by the Federal Courts of Pernambuco. The contingencies were properly updated, as established by legislation. The reduction of the amount is due to the inclusion of debts in the Special Installment Payment Program for ICMS, established by Law No. 17247 of December 27, 2007, and Decrees No. 44695 of December 28, 2007 and No. 44704 of January 15, 2008, in the State of Minas Gerais.

·$21,178 corresponds to lawsuits related to INSS in the lower and appellate courts of Minas Gerais, Rio de Janeiro, Espírito Santo, Pernambuco and Bahia. The consolidated balance refers to lawsuits related to SAT (Occupational Accident Insurance), as well as tax delinquency notices for INSS on outside services relating to the last 10 years for which the National Institute of Social Security understands that Gerdau Açominas S.A. is jointly liable. The assessments were maintained at the administrative level and Gerdau Açominas S.A. filed annulment actions with judicial deposits for the amount under discussion based on the understanding that the right to assess part of the charge has prescribed and that there is no joint liability.

·$17,759 relates to the Emergency Capacity Charge (ECE) (“Encargo de Capacidade Emergencial” - ECE) and Extraordinary Tariff Adjustment (RTE) (“Recomposição Tarifária Extraordinária” - RTE) are charges required in the electricity bills of the industrial units of the Company. According to the Company, these charges are of a tax nature and, as such, are incompatible with the National Tax System set forth in the Federal Constitution. For this reason the constitutionality of these charges is being challenged in court. Lawsuits are in progress in the Federal Courts of Sao Paulo and Rio Grande do Sul, as well as in the Federal Regional Courts, Superior Court of Justice and the Federal Supreme Court (STF). The Company has fully deposited in judicial the amounts of the charges under discussion.

·$63,173 relates the reserve recorded by the subsidiary Gerdau Açominas S.A. is intended to cover amounts required by the Federal Revenue Service for Import Tax, IPI (Federal VAT) and applicable charges on

GERDAU S.A.

(in thousands of U.S. Dollars, unless otherwise stated)

transactions made under a drawback that was subsequently annulled by the Foreign Trade Operations Department (DECEX). The Company does not agree with the administrative decision that annulled the drawback and defends the legality of the transactions made. This issue is under litigation that currently awaits judgment in the Federal Supreme Court (STF).

·The reserve was recorded, considering the legal counsel’s and management’s opinion, for lawsuits assessed as probable loss, in an amount sufficient to cover expected losses.

Possible or remote losses on tax matters for which no provision was recorded

There are other contingent tax liabilities, for which the probability of losses are possible or remote and, therefore, are not recognized in the provision for contingencies. These claims are comprised by:

·The Company is a defendant in a tax collection action filed by the state of Minas Gerais demanding ICMS tax payments mainly on sales of products to commercial exporters. The updated amount of the action is $26,830. The Company did not record any reserve for contingencies for such action since it believes that this tax payment is undue, because products for export are exempted from ICMS (State VAT).

·The Company is a defendant in debt foreclosures filed by the State of Minas Gerais to demand ICMS credits arising mainly from exports of semi-finished processed products. Currently, the total amount demanded is $18,771. The Company has not made any reserve for such claims since it believes that this tax is not applicable, the products do not fall under the definition of semi-finished processed products as established in federal complementary law and, therefore, are not subject to ICMS.

·On December 6, 2000, the Company has entered into Tax Debt Refinancing Program (Programa de Recuperação Fiscal – “REFIS”), paying the Employees’ Profit Participation Program – “PIS” and the Tax for Social Security Financing – “COFINS” contributions in 60 installments, having paid the last one on May 31, 2005. The payment of all the installments for the remaining balance of $11,035 of the REFIS Account was contested. Once the pending issues in the administrative process are solved with the REFIS Management Committee, the Company understands that the installments will become extinct.

·The Company and its subsidiaries Gerdau Aços Longos S.A. and Gerdau Comercial de Aços S.A. have other lawsuits related to the Value-Added Tax on Sales and Services (ICMS) which are mostly related to credit rights and rate differences, and whose demands reach a total of $93,892. An accounting provision was not made for these demands since they were considered of possible loss, but not probable, by our legal advisors.

·The Company and its subsidiary Gerdau Açominas S.A., are parties to the lawsuits relating to Property Tax (IPTU), Import Taxes (II), and Excise Tax (IPI). The total amount of these lawsuits is $10,423. No reserve has been recorded for these lawsuits since they were assessed as possible loss, but not probable, by the legal counsel.

Unrecognized contingent tax assets

Management believes the realization of certain contingent assets is possible. However, no amount has been recognized for these contingent tax assets that would only be recognized upon final realization of the gain:

·The Company believes that the realization of certain contingent assets is possible. Among them is a court-order debt security issued in 1999 in the amount of $13,885, arising from an ordinary lawsuit against the state of Rio de Janeiro for non-compliance with the Loan Agreement for Periodic Execution in Cash under the Special Industrial Development Program (PRODI). Due to the default by the state of Rio de Janeiro and the non-regulation of Constitutional Amendment 30/00 (which granted the government a ten-year moratorium for payment of securities issued to cover court-order debts not related to food), the realization of this asset is not expected in 2008 and following years. For this reason, this asset is not recorded in the Financial Statements.

GERDAU S.A.

(in thousands of U.S. Dollars, unless otherwise stated)

·Also, the Company and its subsidiary Gerdau Açominas S.A. expect to recover Excise Tax (IPI) premium credits. Gerdau S.A. has filed administrative requests for reimbursement, which are pending judgment. With regards to the subsidiary Gerdau Açominas S.A., the proceeding was judged unfavorably. Currently, the proceeding awaits judgment of the appeal filed by the subsidiary. The Company estimates the credits at $170,559 (consolidated). Due to the uncertainty as to its realization, the credit is not recorded.

Labor contingencies

The Company and its subsidiaries are also a party to labor claims, which include indemnity claims for occupational accidents and diseases. None of these claims involve significant amounts and refer mainly to overtime pay, health hazard premium, and hazardous duty premium, among others.

Other contingencies

The Company is also defending in court civil proceedings arising from the normal course of its operations and has accrued $5,243 for these claims. Escrow deposits related to these contingencies, at September 30, 2008, totalized to $13,212.

Other contingent liabilities with remote or possible chances of loss, involving uncertainties as to their occurrence, and therefore, not included in the provision for contingencies, are comprised by:

Antitrust proceeding involving the Company brought by two civil construction unions in the State of São Paulo alleging that Gerdau S.A. and other long steel producers in Brazil share customers, thus violating the antitrust legislation. After investigations carried out by the Economic Law Department (SDE) and based on public hearings, the SDE was of the opinion that a cartel existed. This conclusion was also supported by an earlier opinion by the Secretariat for Economic Monitoring (SEAE). The proceeding was therefore forwarded to the Administrative Council for Economic Defense (CADE) for judgment. However, the proceeding was suspended from May 2004 to August 16, 2005 due to a legal protection granted within a new lawsuit filed by Gerdau S.A. with the purpose of annulling the administrative proceeding grounded on formal irregularities found in its discovery. The annulment of the legal protection by the Federal Regional Court occurred as a result of appeals filed by CADE.

CADE, regardless of the request for submission of negative evidence of cartel made by Gerdau S.A., judged the merits of the administrative proceedings on September 23, 2005 and, by a majority of votes, fined the Company and other long steel producers an amount equivalent to 7% of gross revenues in the year before the Administrative Proceeding was commenced, excluding taxes, for formation of a cartel. The content of this decision proved to be contradictory, forcing Gerdau to seek, at two different moments, clarifications through the Amendment of Judgment – a procedural instrument that does not seek to reexamine the merits of a decision, but rather provide an explanation for the “obscurity,” “contradiction” or “omission” contained in the decision. Both Amendments were judged, disclosed and provided, respectively, on March 29, 2006 and May 24, 2006. It is important to point out that there was no reexamination of the merits of the decision in these judgments, nor do the decisions in the fundamental principal of “Amendments” correspond to new convictions or judgments in a higher court.

Despite the CADE decision, the legal action filed by Gerdau S.A. follows its normal course and, at present, awaits judgment in the lower court. In the event the processual irregularities alleged by Gerdau are recognized by the court, the CADE decision may be annulled. Furthermore, to reverse the terms of the decision by CADE, Gerdau appealed to the Judiciary on July 26, 2006 by bringing a new ordinary suit that not only ratifies the terms of the first suit, but also points out the irregularities found during the course of the administrative proceeding with CADE. The Federal Judge in charge of analyzing the action decided on August 30, 2006, for legal protection purposes, to suspend the effects of CADE’s decision until the Judge’s final decision. The judicial guarantee was performed by a bank guarantee corresponding to 7% on the gross income before taxes

calculated in 1999 ($128,021). For clarity purposes it should be pointed out that because of the current norms for civil lawsuits, this ordinary action is linked to the suit originally proposed. An order was announced on June 28, 2007, which made the parties aware of the decision from the lower court judge about the maintenance of the legal protection granted, after contested by CADE. On July 3, 2008, Gerdau filed a Bill of Exceptions against the interlocutory decision concerning the untimely presentation of defense on the part of CADE.

It should be noted that just prior to the CADE decision, the Public Prosecution Office of the state of Minas Gerais filed a Public Civil Action, based on the above-mentioned SDE decision, and, without mentioning any new elements, alleged that the Company was involved in activities which violated the antitrust legislation. Gerdau S.A. contested this allegation on July 22, 2005. The Company denies any type of anti-competitive conduct and believes, based on information available, including the opinion of its legal counsel, that the administrative proceeding until now has irregularities, some of which are impossible to resolve. In relation to the merit, Gerdau is sure that it did not practice the alleged conduct and, supported by the opinion of renowned experts, believes that it is possible to reverse its conviction.

Insurance claim

A civil lawsuit has been filed by Sul América Cia. Nacional de Seguros against Gerdau Açominas S.A. and Westdeustsche Landesbank Girozentrale, New York Branch (WestLB), for the payment of $21,599 to settle an indemnity claim, which has been deposited in court. The insurance company pleaded doubt in relation to whom payment should be made and alleged that the subsidiary is resisting receiving the payment and settling the matter. The lawsuit was challenged both by the Bank (which claims to have no right to the amount deposited, which settles the doubt raised by Sul América) and by the subsidiary (which claims that there is no such doubt and justification to refuse payment since the amount owed by Sul América is higher than the amount involved). Subsequently, Sul América claimed fault in the Bank’s representation, a matter that has already been settled, and the judicial deposit was withdrawn in December 2004.

Based on the opinion of its legal counsel, the subsidiary assesses the risk of loss as remote and that the sentence will declare the amount payable within the amount stated in the pleading. Also, Gerdau Açominas S.A. filed, prior to this lawsuit, a collection lawsuit for the amounts recognized by the insurance companies. The lawsuits are pending. The subsidiary expects a favorable outcome in this lawsuit. The civil lawsuits arise from an accident on March 23, 2002 with the blast furnace regenerators of the Ouro Branco steel plants, which resulted in the stoppage of several activities, with damages to the steel mill equipment and loss of profits. The equipment and the loss of profits arising from the accidents were covered by an insurance policy. The report on the events and the loss claim for prompt payment were filed with IRB – Brasil Resseguros, and an advance payment of $32,388 was received in 2002.

In 2002, a preliminary and conservative estimate of indemnities related to the coverage of loss of profits and property damages, in the total amount of approximately $57,462, was recorded based on the amount of fixed costs incurred during the period of partial stoppage of the steel mill activities and the immediate expenses to be incurred to recover the equipment temporarily. This estimate approximates the advance received ($32,388) plus the amount proposed by the insurance company as a complement to settle the indemnity ($17,961). Subsequently, new amounts were added to the dispute as stated in the subsidiary’s answer, although not yet recorded. In addition to these amounts, the Company incurred other costs for the recovery of the damage resulting from the accident, as well as other related losses that were listed in its challenge to the lawsuit in progress and which will be confirmed during the discovery phase, when they will be recorded. The case is still in progress with the engineering and accounting experts, who will judicially demonstrate the amounts stated by Gerdau Açominas S.A.

Based on the opinion of its legal counsel, Management considers that the risk of losses from other contingencies affecting the results of operations or the consolidated financial position of the Company is remote.

8Earnings per share (EPS)

Pursuant to SFAS No. 128, “Earnings per Share” the following tables reconcile net income to the amounts used to calculate basic and diluted EPS. All computations of EPS presented below have been retroactively adjusted to reflect the stock bonus of one share per each share hold approved by the Shareholder’s Meeting on May 30, 2008 (Note 7).

The capital of the Company is comprised of Common and Preferred shares. There are no differences between common and preferred shares either related to rights with respect to dividends or the percentage each share represents on the capital of the company or other matters with the only difference being that only common shares are entitled to vote. The preferred shares can not be converted into common shares.

Considering the fact that both classes of shares have the same rights for dividends and ultimately share equally in the distribution of earnings, net income is allocated proportionally to the quantity of Common and Preferred shares, as a manner to ensure net income allocated to each Common and Preferred shares are the same under the two class method for computing earnings per share. Diluted earnings per share reflect the potential dilution resulting from options granted during those years to acquire shares of Gerdau S.A..

9Derivative instruments

The use of derivatives by the Company is limited. Derivative instruments are used to manage clearly identifiable foreign exchange and interest rate risks arising out of the normal course of business.

Gerdau and operations in Brazil

As part of its normal business operations, Gerdau and operations in Brazil have obtained U.S. dollars denominated debt at fixed rates which exposes them to market risk from changes in foreign exchange and interest rates. Changes in the rate of the Brazilian real against the U.S. dollar expose Gerdau and operations in

F-40

GERDAU S.A.

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL INFORMATION (Unaudited)

 (in thousands of U.S. Dollars, unless otherwise stated)

Brazil to foreign exchange gains and losses which are recognized in the statement of income and also to changes in the amount of Brazilian reais necessary to pay such U.S. dollar denominated debt. Changes in interest rates on their fixed rate debt expose Gerdau and operations in Brazil to changes in fair value on its debt. In order to manage such risks, Gerdau and operations in Brazil periodically enters into derivative instruments, primarily cross-currency interest rate swap contracts, and interest rate swaps. Under the swap contracts Gerdau and operations in Brazil has the right to receive on maturity U.S. dollars plus accrued interest at a fixed rate and have the obligation to pay Brazilian reais at a variable rate based on the CDI rate.

Although such instruments mitigate the foreign exchange and interest rate risks, they do not necessarily eliminate them. The Company generally does not hold derivative instruments for trading purposes.

All swaps have been recorded at fair value and realized and unrealized losses are presented in the consolidated statement of income under “Gain (losses) on derivatives, net”.

Options on minority interest in consolidated subsidiaries

On January 10, 2006, the Company completed its acquisition of 40% of Corporación Sidenor S.A. (“Sidenor”), a Spanish steel producer with operations in Spain and Brazil (Aços Villares S.A. — “Aços Villares”). The Santander Group, the Spanish financial conglomerate, and an entity owned by executives of Sidenor, purchased simultaneously 40% and 20% of Sidenor, respectively. The acquisition price of 100% of Sidenor consists of a fixed installment of € 443,820 plus a contingent variable installment to be paid only by the Company. The fixed price paid by the Company on January 10, 2006 for its 40% in Sidenor was € 165,828 ($261,080). The Santander Group has the option to sell its interest in Sidenor to the Company 5 years after the purchase at a fixed price with a fixed interest rate and Sidenor has the right of preference to purchase these shares and also may at any time during the period of the put option validity to require that the Santander Group exercises the put option before the expiration date. Furthermore, the Company consented to guarantee to pay to the Santander Group an agreed amount (the same as the fixed price of the put option mentioned above plus interest accrued using the same fixed interest rate) at any time up to 6 years after exercising the option in the event that Santander Group has not sold the shares acquired up to that date. In this case, if the Santander Group requires payment of the guarantee, the Company has the right to acquire Sidenor’s shares or to indicate a third party to acquire the shares. The amount received for the sale of shares and dividends paid by Sidenor to the Santander Group should be reimbursed to the Company. The Company’s obligation to purchase from Santander Group its 40% interest in Corporación Sidenor is recorded in Minority Interest. As of September 30, 2008, such potential commitment totaled $243,536 ($258,038 as of September 30, 2007 and $266,176 as of December 31, 2007).

During 2007, the subsidiary Gerdau Aços Especiais has reached an agreement with BNDES Participações S.A. (“BNDESPAR”), which is the largest minority shareholder of Aços Villares S.A. (“Villares”). This agreement

F-42

GERDAU S.A.

NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL INFORMATION (Unaudited)

 (in thousands of U.S. Dollars, unless otherwise stated)

provides BNDESPAR a put option to sell its interest of 28.8% in Villares to the Company, for a determinable price. Such price was determined to be the higher of: (a) the offering price included in the public offering the Company has made when the acquisition of Corporación Sidenor was completed in 2006, plus interest of TJLP + 4% p.a., less any dividends paid by Villares capitalized on the same interest, or (b) the price per share of the public offering divided by 130% of the price of Gerdau S.A. shares, which result in a total quantity of options to BNDESPAR. At the end of fifth year of the contract, BNDESPAR has the higher option between (a) or (b) above. From the fifth and up to the seventh year, the option is still outstanding, but the price is only the one described on (a) above. As of December 31, 2007, this put option has no market value, because the underlying asset has a market quotation significantly higher than any of the exercise prices described in (a) and (b) above. Therefore, no liability was recorded regarding this put option at that time. On May 21, 2008 BNDESPAR sold its shares to Metalúrgica Gerdau S.A. and the option ceased to exist.

Gerdau Ameristeel has the purchase option of 16% of the remaining shares of PCS, which can be exercised after 5 years from the purchase date. Additionally, the minority shareholders also have the option to sell the 16% of the remaining shares of PCS to Gerdau Ameristeel, for the established price and also after 5 years from the date of transaction. The established price was set as the EBITDAs average in the 5 last years ended before the option exercise, multiplied by 5. If Gerdau Ameristeel does not execute the purchase option, then the minority shareholders are entitled to execute the put option of their remaining share to Gerdau Ameristeel. In case the purchase/sale option execution is requested, the other party is obligated to sell/purchase the remaining share. This purchase option does not qualify as a derivative under SFAS 133 and because of that, it was not recorded in the financial statements. As of September 30, 2008, the fair value of this purchase option totaled $62,056.

Net investment hedge

According to SFAS 133, as clarified by Derivative Implementation Group (DIG) issue H8, the Company, on September 30, 2008, opted to designate as hedge of part of its net investments in subsidiaries abroad, the operations of Ten Year Bonds described in Note 5b in the amount of $1.5 billion, which were made in order to provide part of the resources for the acquisition of Chaparral Steel Company and Gerdau MacSteel Inc. Based on the regulation and interpretation mentioned above, the Company demonstrated how highly effective a hedge can be when contracting debts for acquiring these companies abroad, whose effects will be measured and recognized directly in a shareholders’ equity account beginning October 1, 2008.

The objective of the hedge is to protect, during the existence of the debt, the amount of part of the Company’s investment in the subsidiaries mentioned above against positive and negative oscillations in the exchange rate. This objective is consistent with the Company’s risk management strategy.

intangible assets. As a result of these acquisitions the Gerdau Executive Committee included goodwill and intangible assets in the identifiable assets as from the fourth quarter of 2007 with the objective of analyzing the relevant goodwill and intangible assets acquired in the 2007 acquisitions. For comparative purposes the corresponding information as of September 30, 2007 has been modified with respect to the original information presented  in order to use the same criteria as of September 30, 2008.

During 2007, the Company started to present its consolidated financial statements under IFRS in substitution of Brazilian GAAP to be in accordance with changes in the Brazilian accounting law.

For comparative purposes the corresponding information as of September 30, 2007 and December 31, 2007 has been modified with respect to the original information presented in order to use the same criteria as of September 30, 2008.

11Income tax reconciliation

A reconciliation of the income taxes in the statement of income to the income taxes calculated at the Brazilian statutory rates is as follows:

Income tax expense	299,817		107,769		889,100		429,003

As of September 30, 2008, the Company had $53.0 million of unrecognized tax benefits not included in the contractual obligations table. Based on the uncertainties associated with the settlement of these items, the Company is unable to make reasonably reliable estimates of the period of the potential cash settlements, if any, with taxing authorities.

The Company has several different tax years open to examinations, since each fiscal authority of each country in which the Company operates has different timing for tax examinations. In most cases, the years from 2003 to 2008 remains open for tax examinations. In the United States and Spain, the years from 2005 to 2008 remains open for tax examinations.

12Pension Plans

Gerdau and other related companies in the Conglomerate co-sponsor contributory pension plans (the “Brazilian Plans”) covering substantially all employees based in Brazil. The Brazilian Plans consists of a plan for the employees of Gerdau and its subsidiaries (“Gerdau Plan”) and one plan for the employees of Gerdau Açominas and its subsidiaries (“Gerdau Açominas Plan”). The Brazilian Plans are mainly defined benefit plans with certain limited defined contributions. Additionally, the Company’s Canadian and American subsidiaries, including Gerdau Ameristeel, sponsor defined benefit plans (the “North American Plans”) covering the majority of their employees. Contributions to the Brazilian Plans and the North American Plans are based on actuarially determined amounts.

The subsidiaries in North America currently provide specified health care benefits to retired employees. Employees who retire after a certain age with specified years of service become eligible for benefits under this unfunded plan.

The following tables summarize the pension benefits cost and postretirement medical benefit cost included in the Company’s consolidated statements of financial position:

VII) The Company, in the normal course of its business, has operations denominated in foreign currencies, resulting from imports, exports, trade accounts payable and receivable, and short and long-term debts to financial institutions. Therefore, significant fluctuations in the exchange rate may result in relevant effects in the Company’s financial statements. Due to the current market condition, especially from September, 2008 on, the Brazilian real has experienced a devaluation comparing with other currencies, mainly the U.S. dollar. On September 30, 2008, the U.S. dollar exchange rate was $1.00 = R$ 1.9143. On December 19, 2008, the U.S. dollar exchange rate was $1.00 = R$ 2.3859, which represents a devaluation of approximately 20% comparing to September 30, 2008. The interim financial information has been prepared in accordance with generally accepted accounting principles in the Untied States (“U.S. GAAP”), issued by Financial Accounting Standards Board (“FASB”), which requires that assets and liabilities denominated in foreign currencies be updated based on the respective exchange rates at the financial statement date and, therefore, do not reflect the effects of changes in exchange rates subsequently to the financial statement date.
