Standards and Interpretations in force

IFRS 7 - Disclosure - Transfers of Financial Assets

In October 2010, the IASB revised IFRS 7. This amendment has the objective of adding disclosures that enable users of financial statements to assess the risk of exposure over transfers of financial assets and the effects of these risks on the entity’s financial position. The change in the standard IFRS 7 is effective for annual periods beginning on or after July 01, 2011. The adoption of this revised standard did not have an impact in the Company’s Consolidated Financial Statements.

Standards and Interpretations of standards not yet effective

IFRS 9 – Financial Instruments

In November 2009, the IASB issued IFRS 9, which has the objective of replacing the standard IAS 39 Financial Instruments: Recognition and Measurement , in three stages. This standard is the first part of stage 1 of IAS 39 replacement and addresses the classification and measurement of financial assets. In October 2010, the IASB added to this standard the requirements for classification and measurement of financial liabilities. This standard and its subsequent change are effective for annual reporting periods beginning on or after January 1, 2015. The Company is assessing the impacts from the adoption of this standard and possible differences compared to IAS 39.

IFRS 10 — Consolidated Financial Statements

In May 2011, the IASB issued IFRS 10. This standard establishes the principles for presentation and preparation of consolidated financial statements when an entity control one or more entities. This standard is effective for annual reporting periods beginning on or after January 1, 2013. The Company is assessing the impact of adopting this standard on its Consolidated Financial Statements.

IFRS 11 — Joint Arrangements

In May 2011, the IASB issued IFRS 11. This standard addresses aspects related to the accounting treatment for jointly-controlled entities and joint operations. This standard also limits the use of proportional consolidation just for joint operations, and also establishes the equity accounting method as the only method acceptable for joint ventures. This standard is effective for annual reporting periods beginning on or after January 1, 2013. The Company has already adopted the equity accounting method for investments in associates and jointly-controlled entities and it is currently assessing the impact of adopting this standard on its Consolidated Financial Statements.

IFRS 12 — Disclosure of Interests in Other Entities

I n May 2011, the IASB issued IFRS 12. This standard addresses aspects related to the disclosure of nature of risks related to interests owned in subsidiaries, jointly-controlled entities and associate companies. This standard is effective for annual reporting periods beginning on or after January 1, 2013. The Company is assessing the impact of adopting this standard on its Consolidated Financial Statements.

IFRS 13 — Fair Value Measurement

I n May 2011, the IASB issued IFRS 13. This standard establishes fair value and consolidates in a single standard the aspects of fair value measurement and establishes the requirements of disclosure related to fair value.

IAS 28 — Investments in Associates and Joint Ventures

I n May 2011, the IASB revised IAS 28.

The Company already adopted the equity accounting method for its investments in associate companies and jointly-controlled entities and is assessing the impact of the other changes of this standard on its Consolidated Financial Statements.

IAS 19 – Employee Benefits

In June 2011, the IASB revised IAS 19. The most significant modification refers to recognizing the changes on defined benefit obligations and plan assets. The modifications require the recognition of changes in defined benefit obligations and fair value of plan assets as they occur, and therefore the elimination of the “corridor approach” allowed in the previous version of IAS 19 and the advanced recognition of past service costs. Additionally, the amendments require that all actuarial gains and losses be recognized immediately through other comprehensive income so that the net asset or liability of the pension plan is recognized in its Consolidated Financial Statements to reflect the full amount of the plan deficit or surplus. The revised standard is effective for annual reporting periods beginning on or after January 1, 2013. The Company is assessing the impact of adopting this standard on its Consolidated Financial Statements.

NOTE 7 – INCOME AND SOCIAL CONTRIBUTION TAXES

The Company’s subsidiaries in Brazil used R$ 6,930 and R$ 11,882 for the three-month and nine-month periods ended on September 30, 2012, respectively, (R$ (1,716) and R$ 6,382 for the three-month and nine-month periods ended on September 30, 2011, respectively) of tax incentives in the form of income tax credits, related to technological innovation, funds for the rights of children and adolescents, PAT (Workers’ Meal Program), and cultural and artistic activities. The units of the subsidiary Gerdau Aços Longos S.A., located in the northeast region of Brazil, will receive until 2013, a 75% reduction in income tax on operating profit, which represents R$ 5,177 and R$ 6,673for the three-month and nine-month period ended on September 30, 2012 (R$ (6,345) and R$ 0 for the three-month and nine-month periods ended on September 30, 2011). The respective tax incentives were recorded directly in the income and social contribution tax account in the statement of income.

As of September 30, 2012, the Company had tax loss carryforwards arising from its operations in Brazil of R$ 540,075 for income tax (R$ 606,139 as of December 31, 2011) and R$ 1,406,705 for social contribution tax (R$ 1,291,616 as of December 31, 2011), representing a deferred tax asset of R$ 261,622 (R$ 267,780 as of December 31, 2011). The Company believes that the amounts will be realized based on future taxable income. In addition to these deferred tax assets, the Company has not recorded a portion of the tax asset of R$ 176,795 (R$ 172,556 as of December 31, 2011), due to the Company’s inability to use the tax loss carryforwards in its subsidiaries. Notwithstanding, these tax loss carryforwards do not have an expiration date.

As of September 30, 2012, the subsidiary Gerdau Ameristeel has a deferred tax asset from tax losses in its operation in Canada in the amount of R$ 138,599 related to income tax (R$ 123,572 as of December 31, 2011). These credits expire on various dates between 2025 and 2031. The subsidiary believes the amounts will be used with future taxable income, and historically the subsidiary has generated enough taxable income to the use of these assets.

As of September 30, 2012, the subsidiary Gerdau Ameristeel had R$ 144,353 (R$ 133,881 as of December 31, 2011) of capital losses that had not been recognized in the Company’s condensed consolidated interim balance sheets. These losses are primarily related to the write-down of the subsidiary’s long-term investments and none of these losses currently have an expiration date except for R$ 66,939 and R$ 1,854 included in the condensed consolidated interim balance sheets as of September 30, 2012 which expires in 2015 and 2016, respectively (R$ 61,836 and R$ 1,713 as of December 31, 2011). The subsidiary had various state tax losses totaling R$ 118,898 (R$ 208,060 as of December 31, 2011) which had not been recognized in the Company’s condensed interim financial statements and which expires between 2012 and 2031. The subsidiary also had R$ 82,920 of state tax credits for the period ended September 30, 2012 (R$ 76,771 as of December 31, 2011), that were not recognized in the Company’s condensed consolidated interim balance sheet. These credits will expire on various dates between 2015 and 2018 with the exception of a portion of R$ 9,130 (R$ 13,147 as of December 31, 2011), which has no expiration date.

In Brazil, income taxes include the federal income tax (IR) and social contribution (CS), which represent an additional federal income tax. The applicable tax rates for income tax and social contribution are 25% and 9%, respectively, for the periods of three and nine months ended on September 30, 2012 and 2011. Beyond the domestic tax rates mentioned above, the Company is also subject to taxes on income in its subsidiaries abroad, which tax rate ranges between 20% and 38.5%.

a) Covenants

Certain debt agreements contain financial covenants as a tool used by creditors to monitor the Company’s financial position. The following is a brief description of the financial covenants required under the Company’s debt agreements.

I) Consolidated Interest Coverage Ratio — measures the interest expense payment capacity in relation to EBITDA (Earnings before Interest, Taxes, Depreciation, Amortization, Impairment and Restructuring Costs) as defined in the bank agreements. The contractual ratio indicates that the EBITDA for the last 12 months should represent at least 3 times of the interest expense of the same period. As of September 30, 2012 such covenant was 4.3 times;

as of September 30, 2012

(In thousands of Brazilian Reais — R$, unless otherwise stated)

(Unaudited)

II) Consolidated Leverage Ratio — measures the level of gross debt in relation to EBITDA as defined in the bank agreements. The contractual ratio indicates that the gross debt should not surpass 4 times the EBITDA for the last 12 months. As of September 30, 2012 such covenant was 3.5 times;

III) Required Minimum Net Worth — measures the minimum net worth required in financial agreements. The contractual ratio indicates that the Net Worth must be greater than R$ 3,795,200. As of September 30, 2012 such level was R$ 28,886,052; and

IV) Current Ratio — measures the company’s ability in fulfilling its short term obligations. The contractual terms indicate that the ratio of Current Assets divided by Current Liabilities must be greater than 0.8 times. As of September 30, 2012 the current ratio was 1.9 times.

All covenants described above are calculated based on the IFRS Consolidated Financial Statements of Gerdau S.A., except item IV, which refers to the Metalúrgica Gerdau S.A. and has been met. The penalty for non-compliance with such financial covenants is the possibility of a declaration of default by the creditors which could cause the loans to become currently due and payable.

The company has established new financial covenant standards in which cash, cash equivalents and financial revenue are considered in the ratios calculations. In accordance with this new strategy, any new financial agreement of the Company and its subsidiaries, which has financial covenants, follows the new standard. The new financial covenants standard is: Net Debt / EBITDA must be less or equal to 4 and EBITDA / Net Financial Expenses must be greater or equal to 3. As of September 30, 2012, the Net Debt / EBITDA was 2.8 times and the EBITDA / Net financial expense was 6.9 times.

Based on the Company’s internal forecasts, the Company does not expect to be in breach of any of the financial covenants over the next twelve months. Nevertheless, this forecast can be affected positive or negatively by the global economics and the steel market.

The fair value of Ten-Year bond Securities is based on quotations in the secondary market for these securities.

All other financial instruments, which are recognized in the Condensed Consolidated Interim Financial Statements at their carrying amount, are substantially similar to those that would be obtained if they were traded in the market. However, because there is no active market for these instruments, differences could exist if they were settled in advance.

c) Risk factors that could affect the Company’s and its subsidiaries’ businesses:

Price risk of commodities: this risk is related to the possibility of changes in prices of the products sold by the Company or in prices of raw materials and other inputs used in the productive process. Since the Company operates in a commodity market, their sales revenues and cost of sales may be affected by changes in the international prices of their products or materials. In order to minimize this risk, the Company constantly monitors the price variations in the domestic and international markets.

Interest rate risk: this risk arises from the possibility of losses (or gains) due to fluctuations in interest rates applied to the Company’s financial liabilities or assets and future cash flows and income. The Company evaluates its exposure to these risks: (i) comparing financial assets and liabilities denominated at fixed and floating interest rates and (ii) monitoring the variations of interest rates like Libor and CDI. Accordingly, the Company may enter into interest rate swaps in order to reduce this risk.

SEQ.=1,FOLIO='',FILE='C:\JMS\105733\12-25799-1\task5636445\25799-1-mm-11.htm',USER='105733',CD='Nov 1 08:34 2012'

(Unaudited)

Exchange rate risk: this risk is related to the possibility of fluctuations in exchange rates affecting the amounts of financial assets or liabilities or of future cash flows and income. The Company assesses its exposure to the exchange rate by measuring the difference between the amount of its assets and liabilities in foreign currency. The company believes that the accounts receivables originated from exports, its cash and cash equivalents denominated in foreign currencies and its investments abroad are more than equivalent to their liabilities denominated in foreign currency. Since the management of these exposures occurs at each operation level, if there is a mismatch between assets and liabilities denominated in foreign currency, the Company may employ derivative financial instruments in order to mitigate the effect of exchange rate fluctuations.

Credit risk: this risk arises from the possibility of the subsidiaries not receiving amounts arising from sales to customers or investments made with financial institutions. In order to minimize this risk, the subsidiaries adopt the procedure of analyzing in details of the financial position of their customers, establishing a credit limit and constantly monitoring their balances. In relation to cash investments, the Company invests solely in financial institutions with low credit risk, as assessed by rating agencies. In addition, each financial institution has a maximum limit for investment, determined by the Company’s Credit Committee.

Capital management risk: this risk comes from the Company’s choice in adopting a financing structure for its operations. The Company manages its capital structure, which consists of a ratio between the financial debts and its own capital (Equity) based on internal policies and benchmarks. The BSC (Balance Scorecard) methodology has been used in the last years to elaborate strategic maps with objectives and indicators of the main processes. The KPIs (Key Performance Indicators) related to the objective “Capital Structure Management” are: WACC (Weighted Average Cost of Capital), Total Indebtedness/adjusted EBITDA, Interest Coverage Ratio, and Indebtedness/Equity Ratio. The Total Debt is composed of loans and financing (note 11) and debentures (note 12). The Company can change its capital structure depending on economic-financial conditions in order to optimize its financial leverage and its debt management. At the same time, the Company tries to improve its ROCE (Return on Capital Employed) by implementing a working capital management process and an efficient fixed asset investment program.

The Company seeks to remain between the following parameters:

WACC between 10% to 13% a year
Gross debt/EBITDA between 3 and 4 times
Interest Coverage Ratio greater than 3 times
Debt/Equity ratio less or equal 60%

These key indicators are used to monitor objectives described above and may not necessarily be used as indicators for other purposes, such as impairment tests.

Liquidity risk: the Company’s management policy of indebtedness and cash on hand is based on using the committed lines and the currently available credit lines with or without a guarantee in export receivables for maintaining adequate levels of short, medium, and long-term liquidity. The maturity of long-term loans, financing, and debentures are presented in Notes 11 and 12, respectively.

Sensitivity analysis:

The Company performed sensitivity analysis, which can be summarized as follows:

Impact in the net income or statement of comprehensive income

Assumption Variation September 30, 2012
Changes in foreign currency 5 % 155,961
Changes in interest rates 0.1 % 83,111
Changes in sales price of goods 1 % 289,940

Foreign currency sensitivity analysis: As of September 30, 2012, the Company is mainly exposed to variations between Brazilian real and US Dollar. The sensitivity analysis made by the Company considers the effects of an increase or a reduction of 5% between the Brazilian real and the US Dollar on debts that do not have hedge operations. The impact calculated considering such variation in the foreign exchange rate totals R$ 155,961 — R$ 74,356 after the effects of changes in the net investment hedge described in note 13.g, as of September 30, 2012 (R$ 41,369 as of September 30, 2011) and represents an income if an appreciation of the Brazilian real against the US Dollar occurs or an expense in the case of a depreciation of the Brazilian real against the US Dollar, however due to the investment hedge these effects would be mitigated.

The net amounts of trade accounts receivable and trade accounts payable denominated in foreign currency do not represent any relevant risk in the case of any fluctuation of exchange rates.

Interest rate sensitivity analysis: The interest rate sensitivity analysis made by the Company considers the effects of an increase or reduction of 0.1% on the average interest rate applicable to the floating part of its debt. The impact calculated considering this variation in the interest rate totals R$ 83,111 as of September 30, 2012 (R$ 72,393 as of September 30, 2011) and would impact the Financial expenses account in the Consolidated Statements of Income. The specific interest rates the Company is exposed, which are related to loans, financing, and debentures are presented in Notes 11 and 12, and are mainly comprised by Libor and CDI — Interbank Deposit Certificate.

Sensitivity analysis of changes in sales price of products and price of raw materials and other inputs used in production: the Company is exposed to changes in the price of its products. This exposure is associated with the fluctuation of the sales price of the Company’s products and the price of raw materials and other inputs used in the production process, especially because the Company operates in a commodities market. The sensitivity analysis made by the Company considers the effects of an increase or of a reduction of 1% on both prices. The impact measured considering this variation in the price of products sold totals R$ 289,940 as of September 30, 2012 (R$ 263,410 as of September 30, 2011) and raw materials and other inputs totals R$ (182,913) as of September 30, 2012 (R$ (163,289) as of September 30, 2011). The impact in the price of products sold and raw materials would be recorded in the accounts Net Sales and Cost of Sales, respectively, in the Consolidated Statements of Income. The Company does not expect to be more vulnerable to a change in one or more specific product or raw material.

Sensitivity analysis of interest rate swaps: the Company has an interest rate swaps exposure for some of its loans and financing. The sensitivity analysis calculated by the Company considers the effects of either an increase or a decrease of 0.1% in the interest curve (Libor), and its impacts in the swaps mark to market. An increase of 0.1% change in the interest rates represents an income of R$ 1,113 (income of R$ 139 as of September 30, 2011) and a decrease of 0.1% change in the interest rates represents an expense of R$ 1,113 (expense of R$ 139 as of September 30, 2011). All these swaps were contracted to hedge debt positions from floating to fix (Liability). On September 30, 2012, these effects were recognized in the statement of comprehensive income and in the statement of income in the amounts of R$ 1,074 and R$ 39, respectively (R$ 139 in the statement of income on September 30, 2011). The effects of changes in cash flow hedges are recorded in the statement of income. The interest rate swaps to which the Company is exposed to are presented in note 13.e.

Sensitivity analysis of currency swaps and NDF’s (Non Deliverable Forwards): the Company has currency swaps ( cross currency swaps ) and NDF’s exposure to some of its assets and liabilities. The sensitivity analysis calculated by the Company considers an effect of a 5% US Dollar depreciation or appreciation against Brazilian Real and Colombian Pesos, and its effects on these derivatives mark to market. An increase of 5% on the US Dollar against these currencies represents an income of R$ 5,755 as of September 30, 2012 (R$ 2,789 as of September, 30 2011) and a decrease of 5% on the US Dollar against these currencies represents an expense of R$ 5,755 as of September 30, 2012 (R$ 2,789 as of September, 30 2011). The Dollar/Real NDF’s were contracted to hedge asset positions (Exports) and these effects of mark to market have been recognized in the statement of comprehensive income. The Dollar/Colombian Pesos NDF’s were contracted to hedge liability positions (Debt) and these effects of mark to market would be recognized in the statement of comprehensive income. The NDF’s to which the Company is exposed are presented in note 13.e.

f) Put options on non-controlling interests

On December 23, 2010, the Santander Group and the Company, through its subsidiary Gerdau Hungria Holdings, renewed the put option on Sidenor interest and the new maturity date is January 10, 2014, and can be settled in advanced in January at each year, beginning 2012. As of September 30, 2012, such potential obligation totaled R$ 583,779 (R$ 528,821 as of December 31, 2011).

The Company, through its subsidiary Gerdau Ameristeel Inc., has the call option for the remaining 1% stake in Pacific Coast Steel (PCS) interest with a fixed price of US$ 3 million. On September 30, 2012, the amount recognized as a potential obligation amounts to R$ 5,355 (R$ 4,723 as of December 31, 2011).

g) Net investment hedge

Based on IFRIC Interpretation 16 issued in July 2008, and substantiated by IAS 39, the Company designated as hedge of part of its net investments in subsidiaries abroad the operations of Ten Year Bonds, contracted by the subsidiary GTL Trade Finance Inc., in the amount of US$ 1.5 billion and by the subsidiary Gerdau Trade Inc., in the amount of US$ 1.25 billion, totaling US$ 2.75 billion. As a consequence, the effect of exchange rate changes on these debts has been recognized in comprehensive income, while the effect of taxation (income and social contribution taxes) is recognized in income.

Starting from April 1, 2012, with the objective of eliminating the tax effect from the exchange variance of these debts, the Company decided to change the value of the net investment hedge designation in foreign subsidiaries for the operations of Ten Years Bonds. Thus, the exchange rate variance over the amount of US$ 1.96 billion will continue to be recognized in equity while the exchange rate variance on the portion of US$ 0.79 billion is recognized in income.

Additionally, the Company chose to designate as hedge part of the net investments in financing operations held by the subsidiary Gerdau Açominas SA, in the amount of US$ 0.6 billion, which were made in order to provide part of the resources for these investments acquisitions abroad.

Based on the standard and interpretation of standard mentioned above, the Company demonstrated high effectiveness of the hedge as from the debt hiring for acquisition of these companies abroad, whose effects were measured and recognized directly in the statement of Comprehensive Income as an unrealized loss in the amount of R$ 370,495 (loss of R$ 572,920 on September 30, 2011).

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.

h) Measurement of fair value:

IAS 32 defines fair value as the amount for which an asset could be exchanged, or a liability settled, between knowledgeable, willing parties in an arm’s length transaction. IFRS 7 establishes a hierarchy of three levels for the fair value, which prioritizes information when measuring the fair value by the company, to maximize the use of observable

Level 1 - quoted prices (unadjusted) in active markets for identical assets and liabilities.

Level 2 - Inputs other than quoted prices included in Level 1 available, where (unadjusted) quoted prices are for similar assets and liabilities in non-active markets, or other data that is available or may be corroborated by market data for substantially the full term of the asset or liability.

Level 3 - Inputs for the asset or liability that are not based on observable market data, because market activity is Insignificant or does not exist.

As of September 30, 2012, the Company had some assets which the fair value measurement is required on a recurring basis. These assets include investments in private securities and derivative instruments.

Expected period until maturity 5 years 5 years 5 years 5 years 5 years 5 years 5 years 5 years 5 years

II) Gerdau Ameristeel Corporation — (“Gerdau Ameristeel”)

In February 2010, the Board of Directors of Gerdau Ameristeel approved the adoption of the Equity Incentive Plan (the “EIP”). Awards under the EIP may take the form of stock options, SARs, deferred share units (“DSUs”), restricted share units (“RSUs”), performance share units (“PSUs”), restricted stock, and/or other share-based awards. Except for stock options, which must be settled in common shares, awards may be settled in cash or common shares as determined by the Gerdau Ameristeel at the time of grant.

For the portion of any award which is payable in options or SARs, the exercise price of the options or SARs will be no less than the fair market value of a common share on the date of the award. The vesting period for all awards (including RSUs, DSUs and PSUs) is determined by the Company at the time of grant. Options and SARs have a maximum term of 10 years.

On March 16, 2012, an award of approximately US$ 9.9 million (R$ 20.1 million) was granted to participants under the EIP for 2011 performance. The Company issued 1,504,780 equity-settled SARs, 97,516 RSUs, and 195,032 PSUs under this plan. This award is being accrued over the vesting period of 5 years.

On March 16, 2011, an award of approximately US$ 11.2 million (R$ 22.7 million) was granted to participants under the EIP for 2010 performance. The Company issued 1,280,082 equity-settled SARs, 107,286 RSUs, and 214,572 PSUs under this plan. This award is being accrued over the vesting period of 5 years.

In connection with the adoption of the EIP, the Company terminated the existing long-term incentive plan (“LTIP”), and no further awards will be granted under the LTIP. All outstanding awards under the LTIP will remain outstanding until either exercised, forfeited or they expire. On September 30, 2012, there were 2,088,113 cash-settled SARs, 1,063,498 stock options, and 89,333 phantom shares outstanding under the LTIP. These awards are being accrued over the vesting period of 4 years.

During the three-month and nine-month periods ended on September 30, 2012, the compensation costs recognized for all equity-settled awards were an expense of US$ 2.2 million (R$ 4.5 million) and US$ 5.8 million (R$ 11.1 million), respectively, and, during the three-month and nine-month periods ended September 30, 2011, the compensation costs recognized were an expense of US$ 1.5 million (R$ 2.5 million) and US$ 4.1 million (R$ 6.7 million), respectively.

During the three-month and nine-month periods ended on September 30, 2012, the compensation costs related to cash-settled awards were expenses of US$ 1.3 million (R$ 2.6 million) and a expense of US$ 3.8 million (R$ 7.3 million), respectively, and, during the three-month and nine-month ended on September 30, 2011, a gain of US$ 5 million (R$ 8.2 million) and US$ 8.4 million (R$ 13.7 million), respectively.

As of September 30, 2012 and December 31, 2011, the outstanding liability for share-based payment transactions included in Other non-current liabilities of Gerdau Ameristeel was US$ 9.5 million (R$ 19.3 million) and US$ 8 million (R$ 15 million), respectively. The total intrinsic value of share-based liabilities for which the participant’s right to cash had vested was US$ 4.8 million (R$ 9.7 million) and US$ 3.1 million (R$ 5.8 million) as of September 30, 2012 and December 31, 2011, respectively.

Phantom Shares

Phantom Shares provide the holder with the opportunity to receive a cash payment equal to the fair market value of the ADSs. Phantom Shares vest 25% each year over a four year period with the holders receiving payment for vested shares on each grant anniversary date. The holders of Phantom Shares have no voting rights, but accumulate additional shares based on notional dividends paid by Gerdau S.A. on its ADRs at each dividend payment date, which are reinvested as additional Phantom Shares. Compensation expense related to Phantom Shares is recognized over the vesting period based upon the number of shares that are expected to vest and remain outstanding at the end of the reporting period. On the date of grant, the fair value of a Phantom Share is equal to the fair value of the underlying reference shares. For Phantom Shares, the fair value is remeasured at each balance sheet reporting date.

Share Appreciation Rights (SARs)

SARs provide the holder with the opportunity to receive either ADRs or a cash payment equal to the fair market value of the ADRs less the grant price. The grant price is set at the closing price of the Company’s common shares on the grant date. SARs have a vesting period of four to five years and expire ten years after the grant date. Expenses with this plan are recognized based on the fair value of the awards that are still in the vesting period and remain outstanding at the end of the reporting period. The Black-Scholes option pricing model is used to calculate an estimate of fair value. Gerdau Ameristeel has SARs that may be settled in shares or in cash. For equity-settled SARs, the fair value is estimated only on the grant date. For cash-settled SARs, the fair value is remeasured at each reporting date.

The grant date fair value of equity-settled SARs granted during the nine-month period ended on September 30, 2012 and 2011 was US$ 4.51 and US$ 5.45 (R$ 8.7 and R$ 8.9), respectively and the principal assumptions used in applying the Black-Scholes option pricing model were as follows:

2012 2011
Dividend yield 2.09 % 2.56 %
Stock price volatility 52.30 % 52.75 %
Risk-free rate of return 1.43 % 2.37 %
Expected period until maturity 6.50 years 6.51 years

The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions. The model requires the use of subjective assumptions. Expected volatility was based on historical volatility of the Company’s stock as well as other companies operating similar businesses. The expected life (in years) was determined using historical data to estimate SARs exercise patterns. The expected dividend yield was based on the historical annualized dividend rates. The risk free interest rate was based on the rate for US Treasury bonds commensurate with the expected term of the granted SARs.

Restricted Share Units (RSUs)

RSUs entitle their holders to receive a certain number of common shares after a determined vesting period. The RSUs have a vesting period of five years. The holders of RSUs have no voting rights, but accumulate additional units based on notional dividends paid by the Company on its common shares at each dividend payment date, which are reinvested as additional RSUs. Expenses related to RSUs are recognized over the vesting period based on the fair value of the Company’s RSUs on the grant date and the awards that are expected to be granted. The fair value is calculated based on the closing price of the Company’s common shares on the grant date. The weighted average fair value of RSUs granted was US$ 10.67 and US$ 13 (R$ 20.50 and R$ 21.23) for the nine-month period ended September 30, 2012 and 2011, respectively.

Performance Share Units (PSUs)

PSUs give the holder the right to receive one common share for each unit that vests on the vesting date as determined by the Company. The holders of PSUs accumulate additional units based upon notional dividends paid by the Company on its ADRs on each dividend payment date, which are reinvested as additional PSUs. The percentage of PSUs initially granted depends upon the Company’s performance over the performance period against pre-established performance goals.

Expenses related to each PSU grant are recognized over the performance period based upon the fair value of the Company’s PSUs on the grant date and the number of units expected to be exercised. The fair value is calculated based on the closing price of the Company’s common shares on the date of grant. The weighted average fair value of PSUs granted was US$ 10.67 and US$ 13 (R$ 20.50 and R$ 21.23) for the nine-month period ended September 30, 2012 and 2011, respectively.

Stock Options

The Company’s stock options vest over a period of four years. The maximum term of an option is 10 years from the date of grant. On the date of grant, the exercise price of options is based on the fair value of the underlying reference shares.

There were no stock options granted during the nine-month period ended on September 30, 2012 and September 30, 2011.

III) Gerdau MacSteel Inc. (“Gerdau MacSteel”)

Gerdau Macsteel Inc. and its subsidiaries have long-term incentive plans that 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 or stock appreciation rights (“SARs”). 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 market value of the Gerdau S.A. ADRs at the date the award of phantom stock is made, based in the average price of Preferred Shares in the New York Stock Exchange. Phantom stock and SAR’s vest 25% on each of the first four anniversaries of the date of the award. Phantom Stock is paid in cash when exercised. An award of approximately US$ 1.7 million (R$ 3.5 million) was earned by participants in the first semester of 2012 and was granted 52% in SARs, 31% in Performance Shares and 17% in Restrict Shares. In 2011 an award of approximately US$ 0.8 million (R$ 1.6 million) was granted to the employees and was issued 41% in SAR’s, 39% in Performance Shares and 20% in Restrict Shares.

The subsidiary Gerdau MacSteel uses the Black-Scholes pricing method to determine the fair value of stock appreciation rights, recognizing the stock compensation cost as services are provided. The subsidiary used the following economic assumptions to recognize the fair value of these instruments:

Performance Shares

2012 Grant 2011 Grant
Dividend yield 2.09 % 2.56 %
Volatility in the share price 52.30 % 52.75 %
Free rate of return risk 1.43 % 2.37 %

NOTE 22 — SEGMENT REPORTING

The Gerdau Executive Committee, which is composed of certain senior officers of the Company, is responsible for managing the business.

Starting in 2012, the operation of metallurgical coal and coke in Colombia, which was previously reported in the Latin America segment, has been considered in the Brazil segment. The change is due to the strategic decision to integrate the operation of coal and coke with Gerdau Açominas, due to its growing importance in the supply of metallurgical coal to that plant. Also from 2012, the Company’s corporate expenses, which were previously reported in Brazil segment, started to be considered in the column “Eliminations and Adjustments.”

For presentation purposes, the comparative information have been modified with respect to the information originally presented, to reflect the changes approved by the Gerdau Executive Committee, according to the criteria established by IFRS 8.

The segments of the Company are as follows: Brazil Operation (includes operations in Brazil, except specialty steels and the operation of metallurgical coal and coke in Colombia), North America Operation (includes all operations in North America, except those in Mexico and specialty steels (Macsteel)), Latin America Operation (includes all operations in Latin America, except Brazil and the operation of metallurgical coal and coke in Colombia) and Specialty Steel Operation (including specialty steel operations in Brazil, Europe, the United States and India).

IFRSs require that the Company discloses the revenue per product unless the information is not available and the cost to obtain it would be excessive. Accordingly, management does not consider this information useful for its decision making process, because it would entail aggregating sales for different markets with different currencies, subject to the effects of exchange differences. Steel consumption patterns and the pricing dynamics of each product or group of products in different countries and different markets within these countries are poorly correlated, and thus the information would not be useful and would not serve to conclude on historical trends and progresses. In light of this scenario and considering that the information on revenue by product is not maintained on a consolidated basis and the cost to obtain revenue per product would be excessive compared to the benefits that would be derived from this information, the Company is not presenting the breakdown of revenue by product.

NOTE 23 — IMPAIRMENT OF ASSETS

The impairment test of goodwill and other long-lived assets is tested based on the analysis and identification of facts or circumstances that may involve the need to perform the impairment test. The Company performs impairment tests of goodwill and other long-lived assets, based on projections of discounted cash flows, which take into account assumptions such as: cost of capital, growth rate and adjustments applied to flows in perpetuity, methodology for working capital determination, investment plans, and long-term economic-financial forecasts. The goodwill impairment test allocated to business segments is performed annually in December, being anticipated if events or circumstances indicate the need of test anticipation.

To determine the recoverable amount of each business segment, the Company used the discounted cash flow method, taking as basis, financial and economic projections to each segment. The projections were updated taken into consideration observed changes in the economic scenario to the market where the Company performs its business, as well as premises of expected results and historical profitability to each segment.

The Company concluded that there are no indications that an impairment test of goodwill and other long-lived assets for the period ended on September 30, 2012 is required.
