Notes to the Consolidated Financial Statements (unaudited)

(dollars in millions, except per-share amounts)

A. Basis of Presentation– The interim Consolidated Financial Statements of Alcoa Inc. and its subsidiaries (“Alcoa” or the “Company”) are unaudited. These Consolidated Financial Statements include all adjustments, consisting of normal recurring adjustments, considered necessary by management to fairly state the Company’s results of operations, financial position, and cash flows. The results reported in these Consolidated Financial Statements are not necessarily indicative of the results that may be expected for the entire year. The 2012 year-end 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 (GAAP). This Form 10-Q report should be read in conjunction with Alcoa’s Annual Report on Form 10-K for the year ended December 31, 2012, which includes all disclosures required by GAAP. Certain amounts in previously issued financial statements were reclassified to confirm to the current period presentation.

B. Recently Adopted and Recently Issued Accounting Guidance

Adopted

On January 1, 2013, Alcoa adopted changes issued by the Financial Accounting Standards Board (FASB) to the testing of indefinite-lived intangible assets for impairment, similar to the goodwill changes adopted in October 2011. These changes provide an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the fair value of an indefinite-lived intangible asset is less than its carrying amount. Such qualitative factors may include the following: macroeconomic conditions; industry and market considerations; cost factors; overall financial performance; and other relevant entity-specific events. If an entity elects to perform a qualitative assessment and determines that an impairment is more likely than not, the entity is then required to perform the existing two-step quantitative impairment test, otherwise no further analysis is required. An entity also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-step quantitative impairment test. Notwithstanding the adoption of these changes, management plans to proceed directly to the two-step quantitative test for Alcoa’s indefinite-lived intangible assets. The adoption of these changes had no impact on the Consolidated Financial Statements.

On January 1, 2013, Alcoa adopted changes issued by the FASB to the disclosure of offsetting assets and liabilities. These changes require an entity to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The enhanced disclosures will enable users of an entity’s financial statements to understand and evaluate the effect or potential effect of master netting arrangements on an entity’s financial position, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments. Other than the additional disclosure requirements (see Note M), the adoption of these changes had no impact on the Consolidated Financial Statements.

On January 1, 2013, Alcoa adopted changes issued by the FASB to the reporting of amounts reclassified out of accumulated other comprehensive income. These changes require an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required to be reclassified in its entirety to net income. For other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures that provide additional detail about those amounts. These requirements are to be applied to each component of accumulated other comprehensive income. Other than the additional disclosure requirements (see below), the adoption of these changes had no impact on the Consolidated Financial Statements.

The changes in Accumulated other comprehensive loss by component were as follows:

Issued

In February 2013, the FASB issued changes to the accounting for obligations resulting from joint and several liability arrangements. These changes require an entity to measure such obligations for which the total amount of the obligation is fixed at the reporting date as the sum of (i) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors, and (ii) any additional amount the reporting entity expects to pay on behalf of its co-obligors. An entity will also be required to disclose the nature and amount of the obligation as well as other information about those obligations. Examples of obligations subject to these requirements are debt arrangements and settled litigation and judicial rulings. These changes become effective for Alcoa on January 1, 2014. Management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements, as Alcoa does not currently have any such arrangements.

In March 2013, the FASB issued changes to a parent entity’s accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. A parent entity is required to release any related cumulative foreign currency translation adjustment from accumulated other comprehensive income into net income in the following circumstances: (i) a parent entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided; (ii) a partial sale of an equity method investment that is a foreign entity; (iii) a partial sale of an equity method investment that is not a foreign entity whereby the partial sale represents a complete or substantially complete liquidation of the foreign entity that held the equity method investment; and (iv) the sale of an investment in a foreign entity. These changes become effective for Alcoa on January 1, 2014. Management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements.

C. Restructuring and Other Charges – In the first quarter of 2013, Alcoa recorded Restructuring and other charges of $7 ($5 after-tax), which were composed of the following components: $3 ($2 after-tax) for layoff costs, including a pension plan settlement charge related to previously separated employees and the voluntary separation of approximately 60 employees (Primary Metals segment), and a net charge of $4 ($3 after-tax) for other miscellaneous items.

In the first quarter of 2012, Alcoa recorded Restructuring and other charges of $10 ($7 after-tax and noncontrolling interests), which were composed of the following components: $11 ($8 after-tax) for the layoff of approximately 220 employees (150 in the Primary Metals segment and 70 in the Engineered Products and Solutions segment), including $6 ($4 after-tax) for the layoff of an additional 150 employees related to the previously reported smelter curtailments in Spain; $1 ($1 after-tax) in other miscellaneous charges; and $2 ($2 after-tax and noncontrolling interests) for the reversal of a number of small layoff reserves related to prior periods.

Alcoa does not include Restructuring and other charges in the results of its reportable segments. The pretax impact of allocating such charges to segment results would have been as follows:

	2013		2012

Global Rolled Products		3		1
Engineered Products and Solutions		3		3
Segment total		6		9
Corporate		1		1
Total restructuring and other charges	$	7	$	10

As of March 31, 2013, all of the employees associated with the 2013 restructuring program, approximately 400 of the 800 employees associated with 2012 restructuring programs, and

9

approximately 900 of the 1,475 employees associated with 2011 restructuring programs were separated. The remaining separations for the 2012 and 2011 restructuring programs are expected to be completed by the end of 2013.

In the 2013 first quarter, cash payments of less than $1, $7, and $4 were made against the layoff reserves related to the 2013, 2012, and 2011 restructuring programs, respectively.

Activity and reserve balances for restructuring charges were as follows:

	Layoff costs			Other exit costs			Total
Reserve balances at December 31, 2011	$	77		$	57		$	134
2012:
Cash payments		(44	)		(13	)		(57	)
Restructuring charges		47			13			60

Reserve balances at December 31, 2012		59			52			111
2013:

Reserve balances at March 31, 2013	$	46		$	50		$	96

* Other includes reversals of previously recorded restructuring charges and the effects of foreign currency translation.

The remaining reserves are expected to be paid in cash during 2013, with the exception of approximately $50 to $55, which is expected to be paid over the next several years for lease termination costs, special separation benefit payments, and ongoing site remediation work.

D. Inventories

Operating supplies		265		263
	$	2,982	$	2,825

At March 31, 2013 and December 31, 2012, the total amount of inventories valued on a last in, first out (LIFO) basis was 36% and 35%, respectively. If valued on an average-cost basis, total inventories would have been $773 and $770 higher at March 31, 2013 and December 31, 2012, respectively.

E. Debt– In January 2013, Alcoa fully borrowed $150 under an existing credit facility, which was repaid in March 2013. This borrowing was subject to an interest rate equivalent to the 1-month LIBOR plus a 1.375% margin. The related revolving credit agreement was terminated effective March 19, 2013.

In the first quarter of 2013, Alcoa entered into three agreements, each with a different financial institution, for a $200 term loan, a $150 revolving credit facility, and a $75 revolving credit facility. The purpose of any borrowings under all three arrangements is to provide working capital and for other general corporate purposes.

The term loan was fully drawn on the same date as the agreement and was subject to an interest rate equivalent to the 1-month LIBOR plus a 1.5% margin. In March 2013, Alcoa and the lender agreed to terminate the term loan and entered into a revolving credit agreement, providing a $200 credit facility. As provided for in the terms of the revolving credit agreement, the outstanding term loan was automatically deemed to be an outstanding borrowing under the credit facility. This borrowing was subject to an interest rate equivalent to the 1-week LIBOR plus a 1.25% margin. As of March 31, 2013, the outstanding borrowing under this credit facility was repaid.

Additionally, in March 2013, Alcoa fully borrowed and repaid the $75 credit facility. This borrowing was subject to an interest rate equivalent to the 1-week LIBOR plus a 0.95% margin.

The $200 revolving credit facility expires in July 2013, the $150 revolving credit facility expires in February 2014, and the $75 revolving credit facility expires in December 2013. The covenants contained

10

in all three arrangements are the same as Alcoa’s Five-Year Revolving Credit Agreement (see the Commercial Paper section of Note K to the Consolidated Financial Statements included in Alcoa’s 2012 Form 10-K).

Also in the first quarter of 2013, Alcoa’s subsidiary, Alumínio, borrowed and repaid a total of $52 in new loans with a weighted-average interest rate of 0.72% and a weighted-average maturity of 70 days from a financial institution. The purpose of these borrowings was to support Alumínio’s export operations.

Litigation

Alba Civil Suit

On February 27, 2008, Alcoa Inc. (“Alcoa”) received notice that Aluminium Bahrain B.S.C. (“Alba”) had filed suit against Alcoa, Alcoa World Alumina LLC (“AWA”), and William Rice (collectively, the “Alcoa Parties”), and others, in the U.S. District Court for the Western District of Pennsylvania (the “Court”), Civil Action number 08-299, styled Aluminium Bahrain B.S.C. v. Alcoa Inc., Alcoa World Alumina LLC, William Rice, and Victor Phillip Dahdaleh. The complaint alleged that certain Alcoa entities and their agents, including Victor Phillip Dahdaleh, had engaged in a conspiracy over a period of 15 years to defraud Alba. The complaint further alleged that Alcoa and its employees or agents (1) illegally bribed officials of the government of Bahrain and/or officers of Alba in order to force Alba to purchase alumina at excessively high prices, (2) illegally bribed officials of the government of Bahrain and/or officers of Alba and issued threats in order to pressure Alba to enter into an agreement by which Alcoa would purchase an equity interest in Alba, and (3) assigned portions of existing supply contracts between Alcoa and Alba for the sole purpose of facilitating alleged bribes and unlawful commissions. The complaint alleged that Alcoa and the other defendants violated the Racketeer Influenced and Corrupt Organizations Act (RICO) and committed fraud. Alba claimed damages in excess of $1,000. Alba’s complaint sought treble damages with respect to its RICO claims; compensatory, consequential, exemplary, and punitive damages; rescission of the 2005 alumina supply contract; and attorneys’ fees and costs.

In response to a motion filed by the U.S. Department of Justice (“DOJ”) on March 27, 2008 (see “Government Investigations” below), the Court ordered the Alba civil suit administratively closed and stayed all discovery to allow the DOJ to fully conduct an investigation. On November 8, 2011, at Alcoa’s request, the Court removed the case from administrative stay and ordered Alba to file an Amended Complaint by November 28, 2011, and a RICO Case Statement 30 days thereafter for the limited purpose of allowing Alcoa to move to dismiss Alba’s lawsuit. Alcoa filed a motion to dismiss, which was denied on June 11, 2012.

During the second quarter of 2012, Alcoa proposed to settle the suit by offering Alba a cash payment of $45. Alcoa also offered Alba a long-term alumina supply contract. Based on the cash offer, Alcoa recorded a $45 ($18 after-tax and noncontrolling interest) charge in the 2012 second quarter representing Alcoa’s estimate of the minimum end of the range probable to settle the case, and estimated an additional reasonably possible charge of up to $75 to settle the suit.

On October 9, 2012, the Alcoa Parties, without admitting any liability, entered into a settlement agreement with Alba. The agreement called for AWA to pay Alba $85 in two equal installments, one-half at time of settlement and one-half one year later, and for the case against the Alcoa Parties to be dismissed with prejudice. Additionally, AWA and Alba entered into a long-term alumina supply agreement. On October 9, 2012, pursuant to the settlement agreement, AWA paid Alba $42.5, and all claims against the Alcoa Parties were dismissed with prejudice. Under the agreement, AWA is obligated to pay an additional $42.5, without interest or contingency, on October 9, 2013. Based on the settlement agreement, in the 2012 third quarter, Alcoa recorded a $40 ($15 after-tax and noncontrolling interest) charge in addition to the $45 ($18 after-tax and noncontrolling interest) charge it recorded in the 2012 second quarter in respect of the suit. In addition, based on an agreement between Alcoa and Alumina Limited (which holds a 40% equity interest in AWA), Alcoa estimates an additional reasonably possible after-tax charge of between $25 to $30 to reallocate a portion of the costs (including legal fees) of the Alba civil settlement from AWA to Alcoa, but this would occur only if a settlement is reached with the DOJ and the Securities and Exchange Commission (the “SEC”) regarding their investigations (see “Government Investigations” below).

Government Investigations

On February 26, 2008, Alcoa Inc. advised the DOJ and the SEC that it had recently become aware of the claims by Alba as alleged in the Alba civil suit, had already begun an internal investigation, and

11

intended to cooperate fully in any investigation that the DOJ or the SEC may commence. On March 17, 2008, the DOJ notified Alcoa that it had opened a formal investigation and Alcoa has been cooperating with the government since that time.

Alcoa is actively negotiating with the DOJ and the SEC to reach a resolution of their investigations of the Alba matter; however, Alcoa has not reached any agreement with either agency. Given the uncertainty regarding whether a settlement can be reached and, if reached, on what terms, Alcoa is not able to estimate a range of reasonably possible loss with regard to any such settlement. If a settlement of the government investigations is reached, Alcoa believes that the settlement amount would be material to Alcoa’s results of operations for the relevant fiscal period. If a settlement cannot be reached, Alcoa will proceed to trial with the DOJ and the SEC and under those circumstances is unable to predict an outcome or to estimate its reasonably possible loss. There can be no assurance that the final outcome of the government’s investigations would not have a material adverse effect on Alcoa.

Other Matters

In November 2006, in Curtis v. Alcoa Inc., Civil Action No. 3:06cv448 (E.D. Tenn.), a class action was filed by plaintiffs representing approximately 13,000 retired former employees of Alcoa or Reynolds Metals Company and spouses and dependents of such retirees alleging violation of the Employee Retirement Income Security Act (ERISA) and the Labor-Management Relations Act by requiring plaintiffs, beginning January 1, 2007, to pay health insurance premiums and increased co-payments and co-insurance for certain medical procedures and prescription drugs. Plaintiffs alleged these changes to their retiree health care plans violated their rights to vested health care benefits. Plaintiffs additionally alleged that Alcoa had breached its fiduciary duty to plaintiffs under ERISA by misrepresenting to them that their health benefits would never change. Plaintiffs sought injunctive and declaratory relief, back payment of benefits, and attorneys’ fees. Alcoa had consented to treatment of plaintiffs’ claims as a class action. During the fourth quarter of 2007, following briefing and argument, the court ordered consolidation of the plaintiffs’ motion for preliminary injunction with trial, certified a plaintiff class, bifurcated and stayed the plaintiffs’ breach of fiduciary duty claims, struck the plaintiffs’ jury demand, but indicated it would use an advisory jury, and set a trial date of September 17, 2008. In August 2008, the court set a new trial date of March 24, 2009 and, subsequently, the trial date was moved to September 22, 2009. In June 2009, the court indicated that it would not use an advisory jury at trial. Trial in the matter was held over eight days commencing September 22, 2009 and ending on October 1, 2009 in federal court in Knoxville, TN before the Honorable Thomas Phillips, U.S. District Court Judge. At the conclusion of evidence, the court set a post-hearing briefing schedule for submission of proposed findings of fact and conclusions of law by the parties and for replies to the same. Post trial briefing was submitted on December 4, 2009.

On March 9, 2011, the court issued a judgment order dismissing plaintiffs’ lawsuit in its entirety with prejudice for the reasons stated in its Findings of Fact and Conclusions of Law. On March 23, 2011, plaintiffs filed a motion for clarification and/or amendment of the judgment order, which seeks, among other things, a declaration that plaintiffs’ retiree benefits are vested subject to an annual cap and an injunction preventing Alcoa, prior to 2017, from modifying the plan design to which plaintiffs are subject or changing the premiums and deductibles that plaintiffs must pay. Also on March 23, 2011, plaintiffs filed a motion for award of attorney’s fees and expenses. Alcoa filed its opposition to both motions on April 11, 2011. On June 11, 2012, the court issued its memorandum and order denying plaintiffs’ motion for clarification and/or amendment to the original judgment order. On July 6, 2012, plaintiffs filed a notice of appeal of the court’s March 9, 2011 judgment. On July 12, 2012, the trial court stayed Alcoa’s motion for assessment of costs pending resolution of plaintiffs’ appeal. The appeal is docketed in the United States Court of Appeals for the Sixth Circuit as case number 12-5801. On July 26, 2012, the appellate court issued a briefing schedule requiring briefing to be complete by the end of October 2012. On August 29, 2012, the trial court dismissed plaintiffs’ motion for attorneys’ fees without prejudice to refiling the motion following the resolution of the appeal at the Sixth Circuit Court of Appeals. Briefing on the appeal is complete and oral argument was held on March 6, 2013. A decision has not yet been rendered by the Sixth Circuit Court of Appeals.

Before 2002, Alcoa purchased power in Italy in the regulated energy market and received a drawback of a portion of the price of power under a special tariff in an amount calculated in accordance with a published resolution of the Italian Energy Authority, Energy Authority Resolution n. 204/1999 (“204/1999”). In 2001, the Energy Authority published another resolution, which clarified that the drawback would be calculated in the same manner, and in the same amount, in either the regulated or unregulated market. At the beginning of 2002, Alcoa left the regulated energy market to purchase energy in the unregulated market. Subsequently, in 2004, the Energy Authority introduced regulation no. 148/2004 which set forth a different method for calculating the special tariff that would result in a different drawback for the regulated and unregulated markets. Alcoa challenged the new regulation in the Administrative Court of Milan and received a favorable judgment in 2006. Following this ruling, Alcoa

12

continued to receive the power price drawback in accordance with the original calculation method, through 2009, when the European Commission declared all such special tariffs to be impermissible “state aid.” In 2010, the Energy Authority appealed the 2006 ruling to the Consiglio di Stato (final court of appeal). On December 2, 2011, the Consiglio di Stato ruled in favor of the Energy Authority and against Alcoa, thus presenting the opportunity for the energy regulators to seek reimbursement from Alcoa of an amount equal to the difference between the actual drawback amounts received over the relevant time period, and the drawback as it would have been calculated in accordance with regulation 148/2004. On February 23, 2012, Alcoa filed its appeal of the decision of the Consiglio di Stato (this appeal was subsequently withdrawn in March 2013). On March 26, 2012, Alcoa received a letter from the agency (Cassa Conguaglio per il Settore Eletrico (CCSE)) responsible for making and collecting payments on behalf of the Energy Authority demanding payment in the amount of approximately $110 (€85), including interest. By letter dated April 5, 2012, Alcoa informed CCSE that it disputes the payment demand of CCSE since (i) CCSE was not authorized by the Consiglio di Stato decisions to seek payment of any amount, (ii) the decision of the Consiglio di Stato has been appealed (see above), and (iii) in any event, no interest should be payable. On April 29, 2012, Law No. 44 of 2012 (“44/2012”) came into effect, changing the method to calculate the drawback. On February 21, 2013, Alcoa received a revised request letter from CSSE demanding Alcoa’s subsidiary, Alcoa Trasformazioni S.r.l., make a payment in the amount of $97 (€76), including interest, which reflects a revised calculation methodology by CCSE and represents the high end of the range of reasonably possible loss associated with this matter of $0 to $97 (€76). Alcoa has rejected that demand and has formally challenged it through an appeal before the Administrative Court on April 5, 2013. At this time, the Company is unable to reasonably predict an outcome for this matter.

European Commission Matters

In July 2006, the European Commission (EC) announced that it had opened an investigation to establish whether an extension of the regulated electricity tariff granted by Italy to some energy-intensive industries complies with European Union (EU) state aid rules. The Italian power tariff extended the tariff that was in force until December 31, 2005 through November 19, 2009 (Alcoa had been incurring higher power costs at its smelters in Italy subsequent to the tariff end date through the end of 2012). The extension was originally through 2010, but the date was changed by legislation adopted by the Italian Parliament effective on August 15, 2009. Prior to expiration of the tariff in 2005, Alcoa had been operating in Italy for more than 10 years under a power supply structure approved by the EC in 1996. That measure provided a competitive power supply to the primary aluminum industry and was not considered state aid from the Italian Government. The EC’s announcement expressed concerns about whether Italy’s extension of the tariff beyond 2005 was compatible with EU legislation and potentially distorted competition in the European market of primary aluminum, where energy is an important part of the production costs.

On November 19, 2009, the EC announced a decision in this matter stating that the extension of the tariff by Italy constituted unlawful state aid, in part, and, therefore, the Italian Government is to recover a portion of the benefit Alcoa received since January 2006 (including interest). The amount of this recovery will be based on a calculation that is being prepared by the Italian Government (see below). In late 2009, after discussions with legal counsel and reviewing the bases on which the EC decided, including the different considerations cited in the EC decision regarding Alcoa’s two smelters in Italy, Alcoa recorded a charge of $250 (€173), which included $20 (€14) to write off a receivable from the Italian Government for amounts due under the now expired tariff structure and $230 (€159) to establish a reserve. On April 19, 2010, Alcoa filed an appeal of this decision with the General Court of the EU. Alcoa will pursue all substantive and procedural legal steps available to annul the EC’s decision. On May 22, 2010, Alcoa also filed with the General Court a request for injunctive relief to suspend the effectiveness of the decision, but, on July 12, 2010, the General Court denied such request. On September 10, 2010, Alcoa appealed the July 12, 2010 decision to the European Court of Justice (ECJ); this appeal was dismissed on December 16, 2011.

In June 2012, Alcoa received formal notification from the Italian Government with a calculated recovery amount of $375 (€303); this amount was reduced by $65 (€53) of amounts owed by the Italian Government to Alcoa, resulting in a net payment request of $310 (€250). In a notice published in the Official Journal of the European Union on September 22, 2012, the EC announced that it had filed an action against the Italian Government on July 18, 2012 to compel it to collect the recovery amount. On September 27, 2012, Alcoa received a request for payment in full of the $310 (€250) by October 31, 2012. Since then, Alcoa has been in discussions with the Italian Government regarding the timing of such payment. Alcoa commenced payment of the requested amount in five quarterly installments of $64 (€50), paying the first installment on October 31, 2012 and the second installment on March 27, 2013. It is possible that Alcoa may be required to accelerate payment or pay the remaining amount in a lump sum. Notwithstanding the payment request or the timing of such payments, Alcoa’s estimate of the most probable loss of the ultimate outcome of this matter and the low end of the range of reasonably possible

13

loss, which is $203 (€159) to $387 (€303), remains the $203 (€159) (the U.S. dollar amount reflects the effects of foreign currency movements since 2009) recorded in 2009. At March 31, 2013, Alcoa’s reserve for this matter stands at $75 (€59), reflecting the payments made in October 2012 and March 2013. The full extent of the loss will not be known until the final judicial determination, which could be a period of several years.

Separately, on November 29, 2006, Alcoa filed an appeal before the General Court (formerly the European Court of First Instance) seeking the annulment of the EC’s decision to open an investigation alleging that such decision did not follow the applicable procedural rules. On March 25, 2009, the General Court denied Alcoa’s appeal. On May 29, 2009, Alcoa appealed the March 25, 2009 ruling before the ECJ. The hearing of the May 29, 2009 appeal was held on June 24, 2010. On July 21, 2011, the ECJ denied Alcoa’s appeal.

As a result of the EC’s November 19, 2009 decision, management had contemplated ceasing operations at its Italian smelters due to uneconomical power costs. In February 2010, management agreed to continue to operate its smelters in Italy for up to six months while a long-term solution to address increased power costs could be negotiated.

Also in February 2010, the Italian Government issued a decree, which was converted into law by the Italian Parliament in March 2010, to provide interruptibility rights to certain industrial customers who were willing to be subject to temporary interruptions in the supply of power (i.e. compensation for power interruptions when grids are overloaded) over a three-year period. Alcoa applied for and was granted such rights (expired on December 31, 2012) related to its Portovesme smelter. In May 2010, the EC stated that, based on their review of the validity of the decree, the interruptibility rights should not be considered state aid. On July 29, 2010, Alcoa executed a new power agreement effective September 1, 2010 through December 31, 2012 for the Portovesme smelter, replacing the short-term, market-based power contract that was in effect since early 2010.

Additionally in May 2010, Alcoa and the Italian Government agreed to a temporary idling of the Fusina smelter. As of June 30, 2010, the Fusina smelter was fully curtailed (44 kmt-per-year).

At the end of 2011, as part of a restructuring of Alcoa’s global smelting system, management decided to curtail operations at the Portovesme smelter during the first half of 2012 due to the uncertain prospects for viable, long-term power, along with rising raw materials costs and falling global aluminum prices (mid-2011 to late 2011). In March 2012, Alcoa decided to delay the curtailment of the Portovesme smelter until the second half of 2012 based on negotiations with the Italian Government and other stakeholders. In September 2012, Alcoa began the process of curtailing the Portovesme smelter, which was fully curtailed by the end of 2012. This curtailment may lead to the permanent closure of the facility; however, Alcoa will keep the smelter in restart condition during 2013.

In January 2007, the EC announced that it had opened an investigation to establish whether the regulated electricity tariffs granted by Spain comply with EU state aid rules. At the time the EC opened its investigation, Alcoa had been operating in Spain for more than nine years under a power supply structure approved by the Spanish Government in 1986, an equivalent tariff having been granted in 1983. The investigation is limited to the year 2005 and is focused both on the energy-intensive consumers and the distribution companies. The investigation provided 30 days to any interested party to submit observations and comments to the EC. With respect to the energy-intensive consumers, the EC opened the investigation on the assumption that prices paid under the tariff in 2005 were lower than a pool price mechanism, therefore being, in principle, artificially below market conditions. Alcoa submitted comments in which the company provided evidence that prices paid by energy-intensive consumers were in line with the market, in addition to various legal arguments defending the legality of the Spanish tariff system. It is Alcoa’s understanding that the Spanish tariff system for electricity is in conformity with all applicable laws and regulations, and therefore no state aid is present in the tariff system. While Alcoa does not believe that an unfavorable decision is probable, management has estimated that the total potential impact from an unfavorable decision could be approximately $90 (€70) pretax. Also, while Alcoa believes that any additional cost would only be assessed for the year 2005, it is possible that the EC could extend its investigation to later years. If the EC’s investigation concludes that the regulated electricity tariffs for industries are unlawful, Alcoa will have an opportunity to challenge the decision in the EU courts.

Environmental Matters

Alcoa continues to participate in environmental assessments and cleanups at a number of locations (more than 100). These include owned or operating facilities and adjoining properties, previously owned or operating facilities and adjoining properties, and waste sites, including Superfund (Comprehensive Environmental Response, Compensation and Liability Act (CERCLA)) sites. A liability is recorded for

14

environmental remediation when a cleanup program becomes probable and the costs or damages can be reasonably estimated.

As assessments and cleanups proceed, the liability is adjusted based on progress made in determining the extent of remedial actions and related costs and damages. The liability can change substantially due to factors such as the nature and extent of contamination, changes in remedial requirements, and technological changes, among others.

Alcoa’s remediation reserve balance was $524 and $532 at March 31, 2013 and December 31, 2012 (of which $68 and $74 was classified as a current liability), respectively, and reflects the most probable costs to remediate identified environmental conditions for which costs can be reasonably estimated. In the 2013 first quarter, the remediation reserve was decreased by $1 associated with a number of sites. The changes to the remediation reserve were recorded in Cost of goods sold on the accompanying Statement of Consolidated Operations.

Payments related to remediation expenses applied against the reserve were $5 in the 2013 first quarter. This amount includes expenditures currently mandated, as well as those not required by any regulatory authority or third party. In the 2013 first quarter, the change in the reserve also reflects a decrease of $2 due to the effects of foreign currency translation.

Included in annual operating expenses are the recurring costs of managing hazardous substances and environmental programs. These costs are estimated to be approximately 2% of cost of goods sold.

The following discussion provides details regarding the current status of certain significant reserves related to current or former Alcoa sites.

Massena West, NY –Alcoa has been conducting investigations and studies of the Grasse River, adjacent to Alcoa’s Massena plant site, under a 1989 order from the U.S. Environmental Protection Agency (EPA) issued under CERCLA. Sediments and fish in the river contain varying levels of polychlorinated biphenyls (PCBs).

Alcoa submitted various Analysis of Alternatives Reports to the EPA starting in 1998 through 2002 that reported the results of river and sediment studies, potential alternatives for remedial actions related to the PCB contamination, and additional information requested by the EPA.

In June 2003, the EPA requested that Alcoa gather additional field data to assess the potential for sediment erosion from winter river ice formation and breakup. The results of these additional studies, submitted in a report to the EPA in April 2004, suggest that this phenomenon has the potential to occur approximately every 10 years and may impact sediments in certain portions of the river under all remedial scenarios. The EPA informed Alcoa that a final remedial decision for the river could not be made without substantially more information, including river pilot studies on the effects of ice formation and breakup on each of the remedial techniques. Alcoa submitted to the EPA, and the EPA approved, a Remedial Options Pilot Study (ROPS) to gather this information. The scope of this study included sediment removal and capping, the installation of an ice control structure, and significant monitoring.

From 2004 through 2008, Alcoa completed the work outlined in the ROPS. In November 2008, Alcoa submitted an update to the EPA incorporating the new information obtained from the ROPS related to the feasibility and costs associated with various capping and dredging alternatives, including options for ice control. As a result, Alcoa increased the reserve associated with the Grasse River by $40 for the estimated costs of a proposed ice control remedy and for partial settlement of potential damages of natural resources.

In late 2009, the EPA requested that Alcoa submit a complete revised Analysis of Alternatives Report in March 2010 to address questions and comments from the EPA and various stakeholders. On March 24, 2010, Alcoa submitted the revised report, which included an expanded list of proposed remedial alternatives, as directed by the EPA. Alcoa increased the reserve associated with the Grasse River by $17 to reflect an increase in the estimated costs of the Company’s recommended capping alternative as a result of changes in scope that occurred due to the questions and comments from the EPA and various stakeholders. While the EPA reviewed the revised report, Alcoa continued with its on-going monitoring and field studies activities. In late 2010, Alcoa increased the reserve by $2 based on the then most recent estimate of costs expected to be incurred for on-going monitoring and field studies activities. In late 2011, the EPA and various stakeholders completed their review of the March 2010 revised report and submitted questions and comments to Alcoa. As a result, Alcoa increased the reserve by $1 to reflect a revision in the estimate of costs expected to be incurred for on-going monitoring and field studies activities.

In the first half of 2012, Alcoa received final questions and comments from the EPA and other stakeholders on the revised Analysis of Alternatives Report submitted in March 2010, including a requirement that would increase the scope of the recommended capping alternative. In June 2012, Alcoa submitted a revised Analysis of Alternatives Report, which included four less alternatives than the previous report and addressed the final questions and comments from all stakeholders. These final questions and comments resulted in a change to Alcoa’s recommended capping alternative by increasing

15

the area to be remediated. Consequently, Alcoa increased the reserve associated with the Grasse River by $37 in the 2012 second quarter to reflect the changes to the recommended alternative.

In the third quarter of 2012, the EPA selected a proposed remedy from the alternatives included in the June 2012 Analysis of Alternatives Report and released a Proposed Remedial Action Plan (PRAP). The alternative selected by the EPA recommends capping PCB contaminated sediments with concentration in excess of one part per million in the main channel of the river and dredging PCB contaminated sediments in the near-shore areas where total PCBs exceed one part per million. This alternative will result in additional estimated costs above that of the alternative recommended by Alcoa in the June 2012 Analysis of Alternatives Report. As a result, Alcoa increased the reserve associated with the Grasse River by $128 in the 2012 third quarter to reflect such additional estimated costs of the EPA’s proposed remedy. The PRAP was open for public comment until November 29, 2012 (extended from November 15, 2012 due to the effects of Hurricane Sandy).

The EPA completed its review of the comments received during the first quarter of 2013 and, on April 5, 2013, issued a final Record of Decision (ROD). The ROD is consistent with the PRAP issued in October 2012, which reflected the EPA’s selection of a remediation alternative estimated to cost $243. As of March 31, 2013, this amount was fully accrued on the accompanying Consolidated Balance Sheet. Alcoa will now begin the planning and design phase, which is expected to take approximately two to three years, followed by the actual remediation fieldwork that is expected to take approximately four years. The majority of the project funding is expected to be spent between 2016 and 2020.

Sherwin, TX –In connection with the sale of the Sherwin alumina refinery, which was required to be divested as part of the Reynolds merger in 2000, Alcoa agreed to retain responsibility for the remediation of the then existing environmental conditions, as well as a pro rata share of the final closure of the active bauxite residue waste disposal areas (known as the Copano facility). Alcoa’s share of the closure costs is proportional to the total period of operation of the active waste disposal areas. Alcoa estimated its liability for the active waste disposal areas by making certain assumptions about the period of operation, the amount of material placed in the area prior to closure, and the appropriate technology, engineering, and regulatory status applicable to final closure. The most probable cost for remediation was reserved.

For a number of years, Alcoa has been working with Sherwin Alumina Company to develop a sustainable closure plan for the active waste disposal areas, which is partly conditioned on Sherwin’s operating plan for the Copano facility. In the second quarter of 2012, Alcoa received the technical analysis of the closure plan and the operating plan from Sherwin in order to develop a closure cost estimate, including an assessment of Alcoa’s potential liability. It was determined that the most probable course of action would result in a smaller liability than originally reserved due to new information related to the amount of storage capacity in the waste disposal areas and revised assumptions regarding Alcoa’s share of the obligation based on the operating plan provided by Sherwin. As such, Alcoa reduced the reserve associated with Sherwin by $30 in the 2012 second quarter.

East St. Louis, IL –In response to questions regarding environmental conditions at the former East St. Louis operations, Alcoa and the City of East St. Louis, the owner of the site, entered into an administrative order with the EPA in December 2002 to perform a remedial investigation and feasibility study of an area used for the disposal of bauxite residue from historic alumina refining operations. A draft feasibility study was submitted to the EPA in April 2005. The feasibility study included remedial alternatives that ranged from no further action to significant grading, stabilization, and water management of the bauxite residue disposal areas. As a result, Alcoa increased the environmental reserve for this location by $15 in 2005.

In April 2012, in response to comments from the EPA and other stakeholders, Alcoa submitted a revised feasibility study to the EPA, which soon thereafter issued a PRAP identifying a soil cover as the EPA’s recommended alternative. Based on this recommendation, Alcoa submitted a detailed design and cost estimate for implementation of the remedy. A draft consent decree was issued in May 2012 by the EPA and all parties are actively engaged in negotiating a final consent decree and statement of work. As a result, Alcoa increased the reserve associated with East St. Louis by $14 in the 2012 second quarter to reflect the necessary costs for this remedy.

On July 30, 2012, the EPA issued a ROD for this matter and Alcoa began the process of bidding and contracting for the construction work. The ultimate outcome of negotiations and the bidding of the construction work could result in additional liability.

Fusina and Portovesme, Italy –In 1996, Alcoa acquired the Fusina smelter and rolling operations and the Portovesme smelter, both of which are owned by Alcoa’s subsidiary Alcoa Trasformazioni S.r.l. (“Trasformazioni”), from Alumix, an entity owned by the Italian Government. At the time of the acquisition, Alumix indemnified Alcoa for pre-existing environmental contamination at the sites. In 2004, the Italian Ministry of Environment (MOE) issued orders to Trasformazioni and Alumix for the development of a clean-up plan related to soil contamination in excess of allowable limits under legislative decree and to institute emergency actions and pay natural resource damages. Trasformazioni appealed the orders and filed suit against Alumix, among others, seeking indemnification for these liabilities under the provisions of

16

the acquisition agreement. In 2009, Ligestra S.r.l. (“Ligestra”), Alumix’s successor, and Trasformazioni agreed to a stay on the court proceedings while investigations were conducted and negotiations advanced towards a possible settlement.

In December 2009, Trasformazioni and Ligestra reached an agreement for settlement of the liabilities related to Fusina while negotiations continued related to Portovesme. The agreement outlines an allocation of payments to the MOE for emergency action and natural resource damages and the scope and costs for a proposed soil remediation project, which was formally presented to the MOE in mid-2010. The agreement is contingent upon final acceptance of the remediation project by the MOE. As a result of entering into this agreement, Alcoa increased the reserve by $12 for Fusina. Based on comments received from the MOE and local and regional environmental authorities, Trasformazioni submitted a revised remediation plan in the first half of 2012; however, such revisions did not require any change to the existing reserve.

Additionally, due to new information derived from the site investigations conducted at Portovesme, Alcoa increased the reserve by $3 in 2009. In November 2011, Trasformazioni and Ligestra reached an agreement for settlement of the liabilities related to Portovesme, similar to the one for Fusina. A proposed soil remediation project for Portovesme was formally presented to the MOE in June 2012. Neither the agreement with Ligestra nor the proposal to the MOE resulted in a change to the reserve for Portovesme.

Baie Comeau, Quebec, Canada –In August 2012, Alcoa presented an analysis of remediation alternatives to the Quebec Ministry of Sustainable Development, Environment, Wildlife and Parks (MDDEP), in response to a previous request, related to known PCBs and polycyclic aromatic hydrocarbons (PAHs) contained in sediments of the Anse du Moulin bay. As such, Alcoa increased the reserve for Baie Comeau by $25 in the 2012 third quarter to reflect the estimated cost of Alcoa’s recommended alternative, consisting of both dredging and capping of the contaminated sediments. The ultimate selection of a remedy may result in additional liability at the time the MDDEP issues a final decision.

Mosjøen, Norway –In September 2012, Alcoa presented an analysis of remediation alternatives to the Norwegian Climate and Pollution Agency (known as “Klif”), in response to a previous request, related to known PAHs in the sediments located in the harbor and extending out into the fjord. As such, Alcoa increased the reserve for Mosjøen by $20 in the 2012 third quarter to reflect the estimated cost of the baseline alternative for dredging of the contaminated sediments. The ultimate selection of a remedy may result in additional liability at the time the Klif issues a final decision.

Other

In March 2013, Alcoa’s subsidiary, Alcoa World Alumina Brasil (AWAB), was notified by the Brazilian Federal Revenue Office (RFB) that approximately $110 (R$220) of value added tax credits previously claimed are being disallowed and a penalty of 50% assessed. Of this amount, AWAB has received $41 (R$82) in cash as of March 31, 2013. The value added tax credits were claimed by AWAB for both fixed assets and export sales related to the Juruti bauxite mine and São Luís refinery expansion. The RFB has disallowed credits they allege belong to the consortium in which AWAB owns an interest and should not have been claimed by AWAB. Credits have also been disallowed as a result of challenges to apportionment methods used, questions about the use of the credits, and an alleged lack of documented proof. The assessment is currently in the administrative process, which could take approximately two years to complete. AWAB presented defense of its claim to the RFB on April 8, 2013. If AWAB is successful in the administrative process, the RFB would have no further recourse. If unsuccessful in this process, AWAB has the option to litigate at a judicial level. The estimated range of reasonably possible loss is $0 to $75 ($R155), whereby the maximum end of the range represents the sum of the portion of the disallowed credits applicable to the export sales and a 50% penalty of the gross amount disallowed. Additionally, the estimated range of disallowed credits related to AWAB’s fixed assets is $0 to $90 (R$175), which would increase the net carrying value of AWAB’s fixed assets if ultimately disallowed. It is management’s opinion that the allegations have no basis; however, at this time, management is unable to reasonably predict an outcome for this matter.

In addition to the matters discussed above, various other lawsuits, claims, and proceedings have been or may be instituted or asserted against Alcoa, including those pertaining to environmental, product liability, safety and health, and tax matters. While the amounts claimed in these other matters may be substantial, the ultimate liability cannot now be determined because of the considerable uncertainties that exist. Therefore, it is possible that the Company’s liquidity or results of operations in a particular period could be materially affected by one or more of these other matters. However, based on facts currently available, management believes that the disposition of these other matters that are pending or asserted will not have a material adverse effect, individually or in the aggregate, on the financial position of the Company.

Commitments

Investments

17

Alcoa has an investment in a joint venture for the development, construction, ownership, and operation of an integrated aluminum complex (bauxite mine, alumina refinery, aluminum smelter, and rolling mill) in Saudi Arabia. The joint venture is owned 74.9% by the Saudi Arabian Mining Company (known as “Ma’aden”) and 25.1% by Alcoa and consists of three separate companies as follows: one each for the mine and refinery, the smelter, and the rolling mill. Alcoa accounts for its investment in the joint venture under the equity method. Capital investment in the project is expected to total approximately $10,800 (SAR 40.5 billion). Alcoa’s equity investment in the joint venture will be approximately $1,100 over a five-year period (2010 through 2014), and Alcoa will be responsible for its pro rata share of the joint venture’s project financing. Alcoa has contributed $740, including $79 in the 2013 first quarter, towards the $1,100 commitment. As of March 31, 2013 and December 31, 2012, the carrying value of Alcoa’s investment in this project was $890 and $816, respectively.

In late 2010, the smelting and rolling mill companies entered into project financing totaling $4,035, of which $1,013 represents Alcoa’s share (the equivalent of Alcoa’s 25.1% interest in the smelting and rolling mill companies). Also, in late 2012, the smelting and rolling mill companies entered into additional project financing totaling $480, of which $120 represents Alcoa’s share. In conjunction with the financings, Alcoa issued guarantees on behalf of the smelting and rolling mill companies to the lenders in the event that such companies default on their debt service requirements through June 2017 and December 2018, respectively, (Ma’aden issued similar guarantees for its 74.9% interest). Alcoa’s guarantees for the smelting and rolling mill companies cover total debt service requirements of $121 in principal and up to a maximum of approximately $60 in interest per year (based on projected interest rates). At both March 31, 2013 and December 31, 2012, the combined fair value of the guarantees was $10 and was included in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. Under the project financings, a downgrade of Alcoa’s credit ratings below investment grade by at least two agencies would require Alcoa to provide a letter of credit or fund an escrow account for a portion or all of Alcoa’s remaining equity commitment to the joint venture project in Saudi Arabia.

In late 2011, the refining and mining company entered into project financing totaling $1,992, of which $500 represents Alcoa World Alumina and Chemical’s (AWAC) 25.1% interest in the refining and mining company. In conjunction with the financing, Alcoa, on behalf of AWAC, issued guarantees to the lenders in the event that the refining and mining company defaults on its debt service requirements through June 2019 (Ma’aden issued similar guarantees for its 74.9% interest). Alcoa’s guarantees for the refining and mining company cover total debt service requirements of $60 in principal and up to a maximum of approximately $25 in interest per year (based on projected interest rates). At both March 31, 2013 and December 31, 2012, the combined fair value of the guarantees was $4 and was included in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. In the event Alcoa would be required to make payments under the guarantees, 40% of such amount would be contributed to Alcoa by Alumina Limited, consistent with its ownership interest in AWAC. Under the project financing, a downgrade of Alcoa’s credit ratings below investment grade by at least two agencies would require Alcoa to provide a letter of credit or fund an escrow account for a portion or all of Alcoa’s remaining equity commitment to the joint venture project in Saudi Arabia.

Alcoa Alumínio (“Alumínio”), a wholly-owned subsidiary of Alcoa, is a participant in four consortia that each owns a hydroelectric power project in Brazil. The purpose of Alumínio’s participation is to increase its energy self-sufficiency and provide a long-term, low-cost source of power for its two smelters and one refinery. These projects are known as Machadinho, Barra Grande, Serra do Facão, and Estreito.

Alumínio committed to taking a share of the output of the Machadinho and Barra Grande projects each for 30 years and the Serra do Facão and Estreito projects each for 26 years at cost (including cost of financing the project). In the event that other participants in any of these projects fail to fulfill their financial responsibilities, Alumínio may be required to fund a portion of the deficiency. In accordance with the respective agreements, if Alumínio funds any such deficiency, its participation and share of the output from the respective project will increase proportionately.

The Machadinho project reached full capacity in 2002. Alumínio’s investment in this project is 30.99%, which entitles Alumínio to approximately 120 megawatts of assured power. In February 2013, the consortium liquidated the legal entity that owned the facility for tax purposes. The consortium is now an unincorporated joint venture, and, therefore, Alumínio’s share of the assets and liabilities of the consortium are reflected in the respective lines on the accompanying Consolidated Balance Sheet. Prior to February 2013, Alumínio’s investment in Machadinho was accounted for under the equity method. In conjunction with the liquidation, the consortium repaid the remaining outstanding debt related to Machadinho, effectively terminating each partner’s guarantee of such debt.

The Barra Grande project reached full capacity in 2006. Alumínio’s investment in this project is 42.18% and is accounted for under the equity method. This entitles Alumínio to approximately 160

18

megawatts of assured power. Alumínio’s total investment in this project was $160 (R$324) and $159 (R$326) at March 31, 2013 and December 31, 2012, respectively.

The Serra do Facão project reached full capacity in 2010. Alumínio’s investment in this project is 34.97% and is accounted for under the equity method. This entitles Alumínio to approximately 65 megawatts of assured power. Alumínio’s total investment in this project was $98 (R$198) and $98 (R$200) at March 31, 2013 and December 31, 2012, respectively. Alumínio previously issued a third-party guarantee related to its share of the consortium’s debt; however, in October 2012, the lender released all of the consortium’s investors from their respective guarantees.

Even though the Serra do Facão project has been fully operational since 2010, construction costs continue to be incurred to complete the facility related to environmental compliance in accordance with the installation license. Total estimated project costs are approximately $500 (R$1,000) and Alumínio’s share is approximately $175 (R$350). As of March 31, 2013, approximately $170 (R$350) of Alumínio’s commitment was expended on the project (includes both funds provided by Alumínio and Alumínio’s share of the long-term financing).

The Estreito project reached full capacity in March 2013. Alumínio’s investment in this project is 25.49%, which entitles Alumínio to approximately 150 megawatts of assured power. The Estreito consortium is an unincorporated joint venture, and, therefore, Alumínio’s share of the assets and liabilities of the consortium are reflected in the respective lines on the accompanying Consolidated Balance Sheet. Total estimated project costs are approximately $2,560 (R$5,170) and Alumínio’s share is approximately $650 (R$1,320). These amounts reflect an approved increase by the consortium in 2012 of approximately $130 (R$270) to complete the Estreito project due to fluctuations in currency, inflation, and the price and scope of construction, among other factors. As of March 31, 2013, approximately $620 (R$1,250) of Alumínio’s commitment was expended on the project.

As of March 31, 2013, Alumínio’s current power self-sufficiency satisfies approximately 70% of a total energy demand of approximately 690 megawatts from two smelters (São Luís (Alumar) and Poços de Caldas) and one refinery (Poços de Caldas) in Brazil.

In 2004, Alcoa acquired a 20% interest in a consortium, which subsequently purchased the Dampier to Bunbury Natural Gas Pipeline (DBNGP) in Western Australia, in exchange for an initial cash investment of $17 (A$24). The investment in the DBNGP, which is classified as an equity investment, was made in order to secure a competitively priced long-term supply of natural gas to Alcoa’s refineries in Western Australia. Alcoa has made additional contributions of $141 (A$176) for its share of the pipeline capacity expansion and other operational purposes of the consortium through September 2011. No further expansion of the pipeline’s capacity is planned at this time. In late 2011, the consortium initiated a three-year equity call plan to improve its capitalization structure. This plan requires Alcoa to contribute $40 (A$40), of which $21 (A$21) was made through March 31, 2013, including $4 (A$4) in the 2013 first quarter. In addition to its equity ownership, Alcoa has an agreement to purchase gas transmission services from the DBNGP. At March 31, 2013, Alcoa has an asset of $364 (A$350) representing prepayments made under the agreement for future gas transmission services. Alcoa’s maximum exposure to loss on the investment and the related contract is approximately $520 (A$500) as of March 31, 2013.

H. Segment Information – On January 1, 2013, management revised the inventory-costing method used by certain locations within the Global Rolled Products and Engineered Products and Solutions segments, which affects the determination of the respective segment’s profitability measure, After-tax operating income (ATOI). Management made the change in order to improve internal consistency and enhance industry comparability. This revision does not impact the consolidated results of Alcoa. Segment information for all prior periods presented was revised to reflect this change.

19

The operating results of Alcoa’s reportable segments were as follows (differences between segment totals and consolidated totals are in Corporate):

	Alumina			Primary Metals			Global Rolled Products			Engineered Products and Solutions		Total

Items required to reconcile total segment ATOI to consolidated net income attributable to Alcoa include: the impact of LIFO inventory accounting; interest expense; noncontrolling interests; corporate expense (general administrative and selling expenses of operating the corporate headquarters and other global administrative facilities, along with depreciation and amortization on corporate-owned assets); restructuring and other charges; discontinued operations; and other items, including intersegment profit eliminations, differences between tax rates applicable to the segments and the consolidated effective tax rate, the results of the soft alloy extrusions business in Brazil, and other nonoperating items such as foreign currency transaction gains/losses and interest income.

I. Earnings Per Share – Basic earnings per share (EPS) amounts are computed by dividing earnings, after the deduction of preferred stock dividends declared and dividends and undistributed earnings allocated to participating securities, by the average number of common shares outstanding. Diluted

20

EPS amounts assume the issuance of common stock for all potentially dilutive share equivalents outstanding not classified as participating securities.

The information used to compute basic and diluted EPS attributable to Alcoa common shareholders was as follows (shares in millions):

	First quarter ended March 31,
	2013		2012
Net income attributable to Alcoa common shareholders	$	149	$	94
Less: preferred stock dividends declared		1		1
Net income available to common equity		148		93
Less: dividends and undistributed earnings allocated to participating securities		—		—
Net income available to Alcoa common shareholders – basic		148		93
Add: interest expense related to convertible notes		8		8
Net income available to Alcoa common shareholders – diluted	$	156	$	101
Average shares outstanding – basic		1,069		1,066
Effect of dilutive securities:
Stock options		3		4
Stock and performance awards		8		5
Convertible notes		89		89
Average shares outstanding – diluted		1,169		1,164

Participating securities are defined as unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) and are included in the computation of earnings per share pursuant to the two-class method. Prior to January 1, 2010, under Alcoa’s stock-based compensation programs, certain employees were granted stock and performance awards, which entitle those employees to receive nonforfeitable dividends during the vesting period on a basis equivalent to the dividends paid to holders of Alcoa’s common stock. As such, these unvested stock and performance awards met the definition of a participating security. Under the two-class method, all earnings, whether distributed or undistributed, are allocated to each class of common stock and participating securities based on their respective rights to receive dividends. At March 31, 2013, there were no outstanding participating securities, as all such securities have vested and were converted into shares of common stock. At March 31, 2012, there were less than 1 million participating securities outstanding.

Effective January 1, 2010, new grants of stock and performance awards do not contain a nonforfeitable right to dividends during the vesting period. As a result, an employee will forfeit the right to dividends accrued on unvested awards if that person does not fulfill their service requirement during the vesting period. As such, these awards are not treated as participating securities in the EPS calculation as the employees do not have equivalent dividend rights as common shareholders. These awards are included in the EPS calculation utilizing the treasury stock method similar to stock options. At March 31, 2013 and 2012, there were 17 million and 12 million such awards outstanding, respectively.

Options to purchase 31 million and 28 million shares of common stock at a weighted average exercise price of $12.20 and $15.47 per share were outstanding as of March 31, 2013 and 2012, respectively, but were not included in the computation of diluted EPS because they were anti-dilutive, as the exercise prices of the options were greater than the average market price of Alcoa’s common stock.

J.Income Taxes – The effective tax rate for the first quarter of 2013 and 2012 was 27.4% and 28.3%, respectively.

The rate for the 2013 first quarter differs from the U.S. federal statutory rate of 35% primarily due to a $19 discrete income tax benefit related to new U.S. tax legislation.

On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law and reinstated various expired or expiring temporary business tax provisions through 2013. Two specific temporary business tax provisions that expired in 2011 and impacted Alcoa are the look-through rule for payments between related controlled foreign corporations and the research and experimentation credit. The expiration of these two provisions resulted in Alcoa recognizing a higher income tax provision of $19 in 2012. As tax law changes are accounted for in the period of enactment, Alcoa recognized the previously mentioned discrete income tax benefit in the 2013 first quarter related to the 2012 tax year to reflect the extension of these provisions.

The rate for the 2012 first quarter differs from the U.S. federal statutory rate of 35% primarily due to foreign income taxed in lower rate jurisdictions.

K. Receivables – Alcoa had three arrangements, each with a different financial institution, to sell certain customer receivables outright without recourse on a continuous basis. On March 22, 2013, Alcoa terminated these arrangements. All receivables sold under these arrangements were collected as of March 31, 2013. Alcoa serviced the customer receivables for the financial institutions at market rates; therefore, no servicing asset or liability was recorded.

Alcoa has an arrangement with a financial institution to sell certain customer receivables without recourse on a revolving basis. The sale of such receivables is completed through the use of a bankruptcy remote special purpose entity, which is a consolidated subsidiary of Alcoa. This arrangement provides for minimum funding of $50 up to a maximum of $250 for receivables sold. The initial sale of receivables in

21

March 2012 resulted in the setup of a deferred purchase price of $254. In addition to the $205 in cash funding received in 2012, Alcoa received additional cash funding of $45 in the first quarter of 2013. As of March 31, 2013, the deferred purchase price receivable was $15, which was included in Other receivables on the accompanying Consolidated Balance Sheet. The deferred purchase price receivable is reduced as collections of the underlying receivables occur; however, as this is a revolving program, the sale of new receivables will result in an increase in the deferred purchase price receivable. The net change in the deferred purchase price receivable was reflected in the (Increase) in receivables line item on the accompanying Statement of Consolidated Cash Flows. This activity is reflected as an operating cash flow because the related customer receivables are the result of an operating activity with an insignificant, short-term interest rate risk. The gross amount of receivables sold and total cash collections under this program since its inception was $4,390 and $4,125, respectively. Alcoa services the customer receivables for the financial institution at market rates; therefore, no servicing asset or liability was recorded.

L. Pension and Other Postretirement Benefits – The components of net periodic benefit cost were as follows:

	Pension benefits						Other postretirement benefits
First quarter ended March 31,	2013			2012			2013			2012
Service cost	$	51		$	47		$	4		$	4

Net periodic benefit cost	$	135		$	106		$	37		$	39

* This amount was recorded in Restructuring and other charges on the accompanying Statement of Consolidated Operations (see Note C).

M. Derivatives and Other Financial Instruments

Derivatives

Alcoa is exposed to certain risks relating to its ongoing business operations, including financial, market, political, and economic risks. The following discussion provides information regarding Alcoa’s exposure to the risks of changing commodity prices, interest rates, and foreign currency exchange rates.

Alcoa’s commodity and derivative activities are subject to the management, direction, and control of the Strategic Risk Management Committee (SRMC), which is composed of the chief executive officer, the chief financial officer, and other officers and employees that the chief executive officer selects. The SRMC meets on a periodic basis to review derivative positions and strategy and reports to Alcoa’s Board of Directors on the scope of its activities.

The aluminum, energy, interest rate, and foreign exchange contracts are held for purposes other than trading. They are used primarily to mitigate uncertainty and volatility, and to cover underlying exposures. Alcoa is not involved in trading activities for energy, weather derivatives, or other nonexchange commodity trading activities.

The fair values and corresponding classifications under the appropriate level of the fair value hierarchy of outstanding derivative contracts recorded as assets in the accompanying Consolidated Balance Sheet were as follows:

** All margin held is in the form of cash and is valued under a Level 1 technique. The levels that correspond to the margin held in the table above reference the level of the corresponding asset for which it is held. Alcoa elected to net the margin held against the fair value amounts recognized for derivative instruments executed with the same counterparties under master netting arrangements.

The fair values and corresponding classifications under the appropriate level of the fair value hierarchy of outstanding derivative contracts recorded as liabilities in the accompanying Consolidated Balance Sheet were as follows:

* The asset and liability amounts as of December 31, 2012 include $9 of margin held from counterparties.

** The asset and liability amounts as of March 31, 2013 and December 31, 2012 represent margin held from the counterparty.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:

• Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

• Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3 – Inputs that are both significant to the fair value measurement and unobservable.

The following section describes the valuation methodologies used by Alcoa to measure derivative contracts at fair value, including an indication of the level in the fair value hierarchy in which each instrument is generally classified. Where appropriate, the description includes details of the valuation models, the key inputs to those models, and any significant assumptions. These valuation models are reviewed and tested at least on an annual basis.

Derivative contracts are valued using quoted market prices and significant other observable and unobservable inputs. Such financial instruments consist of aluminum, energy, interest rate, and foreign exchange contracts. The fair values for the majority of these derivative contracts are based upon current quoted market prices. These financial instruments are typically exchange-traded and are generally classified within Level 1 or Level 2 of the fair value hierarchy depending on whether the exchange is deemed to be an active market or not.

For certain derivative contracts whose fair values are based upon trades in liquid markets, such as interest rate swaps, valuation model inputs can generally be verified through over-the-counter markets and valuation techniques do not involve significant management judgment. The fair values of such financial instruments are generally classified within Level 2 of the fair value hierarchy.

Alcoa has other derivative contracts that do not have observable market quotes. For these financial instruments, management uses significant other observable inputs (e.g., information concerning time premiums and volatilities for certain option type embedded derivatives and regional premiums for aluminum contracts). For periods beyond the term of quoted market prices for aluminum, Alcoa uses a model that estimates the long-term price of aluminum by extrapolating the 10-year London Metal Exchange (LME) forward curve. For periods beyond the term of quoted market prices for energy, management has developed a forward curve based on independent consultant market research. Where appropriate, valuations are adjusted for various factors such as liquidity, bid/offer spreads, and credit considerations. Such adjustments are generally based on available market evidence (Level 2). In the absence of such evidence, management’s best estimate is used (Level 3). If a significant input that is

24

unobservable in one period becomes observable in a subsequent period, the related asset or liability would be transferred to the appropriate level classification (1 or 2) in the period of such change.

The following table presents Alcoa’s derivative contract assets and liabilities that are measured and recognized at fair value on a recurring basis classified under the appropriate level of the fair value hierarchy (there were no transfers in or out of Levels 1 and 2 during the periods presented):

	March 31, 2013			December 31, 2012
Assets:
Level 1	$	5		$	27
Level 2		42			45
Level 3		530			550
Margin held		(14	)		(26	)

Liabilities:
Level 1	$	68		$	15
Level 2		16			26
Level 3		510			638
Total	$	594		$	679

Financial instruments classified as Level 3 in the fair value hierarchy represent derivative contracts in which management has used at least one significant unobservable input in the valuation model. The following tables present a reconciliation of activity for such derivative contracts:

	Assets					Liabilities

* There were no purchases, sales, issuances or settlements of Level 3 financial instruments. Additionally, there were no transfers of financial instruments into or out of Level 3.

As reflected in the table above, the net unrealized gain on derivative contracts using Level 3 valuation techniques was $20 as of March 31, 2013. This gain was mainly attributed to embedded derivatives in power contracts that index the price of power to the LME price of aluminum. These embedded derivatives are primarily valued using observable market prices; however, due to the length of the contracts, the valuation model also requires management to estimate the long-term price of aluminum

25

based upon an extrapolation of the 10-year LME forward curve. Significant increases or decreases in the actual LME price beyond 10 years would result in a higher or lower fair value measurement. An increase of actual LME price over the inputs used in the valuation model will result in a higher cost of power and a corresponding increase to the liability. The embedded derivatives have been designated as hedges of forward sales of aluminum and related realized gains and losses were included in Sales on the accompanying Statement of Consolidated Operations.

In July 2012, as provided for in the arrangements, management elected to modify the pricing for two existing power contracts, which end in 2014 and 2016 (see directly below), for Alcoa’s two smelters in Australia and the Point Henry rolling mill in Australia. These contracts contain an LME-linked embedded derivative, which previously was not recorded as an asset in Alcoa’s Consolidated Balance Sheet. Beginning on January 1, 2001, all derivative contracts were required to be measured and recorded at fair value on an entity’s balance sheet under GAAP; however, an exception existed for embedded derivatives upon meeting certain criteria. The LME-linked embedded derivative in these two contracts met such criteria at that time. Management’s election to modify the pricing of these contracts qualifies as a significant change to the contracts thereby requiring that the contracts now be evaluated under derivative accounting as if they were new contracts. As a result, Alcoa recorded a derivative asset in the amount of $596 with an offsetting liability (deferred credit) recorded in Other current and non-current liabilities. Unrealized gains and losses from the embedded derivative were included in Other income, net on the accompanying Statement of Consolidated Operations, while realized gains and losses were included in Cost of goods sold on the accompanying Statement of Consolidated Operations as electricity purchases are made under the contracts. The deferred credit is recognized in Other income, net on the accompanying Statement of Consolidated Operations as power is received over the life of the contracts. The embedded derivative is valued using the probability and interrelationship of future LME prices, Australian dollar to U.S. dollar exchange rates, and the U.S. consumer price index. Significant increases or decreases in the LME price would result in a higher or lower fair value measurement. An increase in actual LME price over the inputs used in the valuation model will result in a higher cost of power and a decrease to the embedded derivative asset.

Also, included within Level 3 measurements is a derivative contract that will hedge the anticipated power requirements at Alcoa’s Portland smelter in Australia once the existing contract expires in 2016. This derivative hedges forecasted power purchases through December 2036. Beyond the term where market information is available, management has developed a forward curve, for valuation purposes, based on independent consultant market research. The effective portion of gains and losses on this contract was recorded in Other comprehensive income on the accompanying Consolidated Balance Sheet until the designated hedge period begins in 2016. Once the hedge period begins, realized gains and losses will be recorded in Cost of goods sold. Significant increases or decreases in the power market may result in a higher or lower fair value measurement. Higher prices in the power market would cause the derivative asset to increase in value. Alcoa had a similar contract for its Point Henry smelter in Australia once the existing contract expires in 2014, but elected to terminate the new contract in the first quarter of 2013. This election was available to Alcoa under the terms of the contract and was made due to a projection that suggested the contract would be uneconomical. Prior to termination, the new contract was accounted for in the same manner as the contract for the Portland smelter.

Additionally, Alcoa has a six-year natural gas supply contract, which has an LME-linked ceiling. This contract is valued using probabilities of future LME aluminum prices and the price of Brent crude oil (priced on Platts), including the interrelationships between the two commodities subject to the ceiling. Any change in the interrelationship would result in a higher or lower fair value measurement. An LME ceiling was embedded into the contract price to protect against an increase in the price of oil without a corresponding increase in the price of LME. An increase in oil prices with no similar increase in the LME price would limit the increase of the price paid for natural gas. At inception, this contract had a fair value of $5. Unrealized gains and losses from this contract were included in Other income, net on the accompanying Statement of Consolidated Operations, while realized gains and losses will be included in Cost of goods sold on the accompanying Statement of Consolidated Operations as gas purchases are made under the contract.

Furthermore, an embedded derivative in a power contract that indexes the difference between the long-term debt ratings of Alcoa and the counterparty from any of the three major credit rating agencies is included in Level 3. Management uses market prices, historical relationships, and forecast services to determine fair value. Significant increases or decreases in any of these inputs would result in a lower or higher fair value measurement. A wider credit spread between Alcoa and the counterparty would result in an increase of the future liability and a higher cost of power. Realized gains and losses for this embedded derivative were included in Cost of goods sold on the accompanying Statement of Consolidated Operations and unrealized gains and losses were included in Other income, net on the accompanying Statement of Consolidated Operations.

The following table presents quantitative information for Level 3 derivative contracts:

Fair Value Hedges

For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivative as well as the loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings. The gain or loss on the hedged items are included in the same line items as the loss or gain on the related derivative contracts as follows (there were no contracts that ceased to qualify as a fair value hedge in any of the periods presented):

	Location of Gain or (Loss)	Amount of Gain or (Loss)   Recognized in Earnings on Derivatives
	Recognized in Earnings on	First quarter ended March 31,
Derivatives in Fair Value Hedging Relationships	Derivatives	2013			2012
Aluminum contracts*	Sales	$	(71	)	$	36
Interest rate contracts	Interest expense		3			3

Interest rate contracts	Interest expense		(3	)		(3	)
Total		$	68		$	(51	)

* In the first quarter ended March 31, 2012, the gain recognized in earnings includes a loss of $12 related to the ineffective portion of the hedging relationships.

Aluminum. Alcoa is a leading global producer of primary aluminum and fabricated aluminum products. As a condition of sale, customers often require Alcoa to enter into long-term, fixed-price commitments. These commitments expose Alcoa to the risk of fluctuating aluminum prices between the time the order is committed and the time that the order is shipped. Alcoa’s aluminum commodity risk management policy is to manage, principally through the use of futures and contracts, the aluminum price risk associated with a portion of its firm commitments. These contracts cover known exposures, generally within three years. As of March 31, 2013, Alcoa had 430 kmt of aluminum futures designated as fair value hedges. The effects of this hedging activity will be recognized over the designated hedge periods in 2013 to 2016.

Interest Rates.Alcoa uses interest rate swaps to help maintain a strategic balance between fixed- and floating-rate debt and to manage overall financing costs. As of March 31, 2013, the Company had pay floating, receive fixed interest rate swaps that were designated as fair value hedges. These hedges effectively convert the interest rate from fixed to floating on $200 of debt through 2018. In January 2012, interest rate swaps with a notional amount of $315 expired in conjunction with the repayment of 6% Notes, due 2012.

Cash Flow Hedges

For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income (OCI) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings.

	Amount of Gain or (Loss) Recognized in OCI on Derivatives (Effective Portion)					Location of Gain or (Loss) Reclassified from Accumulated OCI into	Amount of Gain or (Loss) Reclassified from Accumulated OCI into Earnings (Effective Portion)*						Location of Gain or (Loss) Recognized in Earnings on Derivatives (Ineffective Portion and Amount	Amount of Gain or (Loss) Recognized in Earnings on Derivatives (Ineffective Portion and Amount Excluded from Effectiveness Testing)**

Total	$	107	$	(82	)		$	(6	)	$	(1	)		$	—	$	7

* Assuming market rates remain constant with the rates at March 31, 2013, a loss of $16 is expected to be recognized in earnings over the next 12 months.

** For the first quarter ended March 31, 2013 and 2012, the amount of gain or (loss) recognized in earnings represents less than $1 and $9, respectively, related to the ineffective portion of the hedging relationships. There was also $(2) recognized in earnings related to the amount excluded from the assessment of hedge effectiveness for the first quarter ended March 31, 2012.

Aluminum and Energy. Alcoa anticipates the continued requirement to purchase aluminum and other commodities, such as electricity and natural gas, for its operations. Alcoa enters into forwards, futures, and options contracts to reduce volatility in the price of these commodities. Alcoa has also entered into power supply and other contracts that contain pricing provisions related to the LME aluminum price. The LME-linked pricing features are considered embedded derivatives. A majority of these embedded derivatives have been designated as cash flow hedges of future sales of aluminum.

Also, Alcoa has a contract to hedge the anticipated power requirements at its Portland smelter in Australia. This derivative hedges forecasted power purchases through December 2036. Prior to the first quarter of 2013, Alcoa had a similar contract for its Point Henry smelter in Australia but elected to terminate it under the terms of the contract (see additional information in description of Level 3 derivative contracts above).

Interest Rates. Alcoa had no outstanding cash flow hedges of interest rate exposures as of March 31, 2013. An investment accounted for on the equity method by Alcoa has entered into interest rate

28

contracts, which are designated as cash flow hedges. Alcoa’s share of the activity of these cash flow hedges is reflected in the table above.

Foreign Exchange. Alcoa is subject to exposure from fluctuations in foreign currency exchange rates. Contracts may be used from time to time to hedge the variability in cash flows from the forecasted payment or receipt of currencies other than the functional currency. These contracts covered periods consistent with known or expected exposures through 2013.

Alcoa had the following outstanding forward contracts that were entered into to hedge forecasted transactions:

	March 31, 2013		December 31, 2012
Aluminum contracts (kmt)		1,085		1,120
Energy contracts:
Electricity (megawatt hours)		59,409,328		100,578,295
Natural gas (million British thermal units)		19,250,000		19,160,000
Foreign exchange contracts	$	86	$	71

Other

Alcoa has certain derivative contracts that do not qualify for hedge accounting treatment and, therefore, the fair value gains and losses on these contracts are recorded in earnings as follows:

Derivatives Not Designated as Hedging Instruments	Location of Gain or (Loss) Recognized in Earnings on Derivatives	Amount of Gain or (Loss) Recognized in Earnings on Derivatives
		First quarter ended March 31,
		2013			2012
Aluminum contracts	Sales	$	(4	)	$	3
Aluminum contracts	Other income, net		22			(7	)
Embedded credit derivative	Other income, net		(2	)		—
Foreign exchange contracts	Other income, net		(3	)		1
Total		$	13		$	(3	)

The aluminum contracts relate to derivatives (recognized in Sales) and embedded derivatives (recognized in Other income, net) entered into to minimize Alcoa’s price risk related to other customer sales and certain pricing arrangements.

The embedded credit derivative relates to a power contract that indexes the difference between the long-term debt ratings of Alcoa and the counterparty from any of the three major credit rating agencies. If the counterparty’s lowest credit rating is greater than one rating category above Alcoa’s credit ratings, an independent investment banker would be consulted to determine a hypothetical interest rate for both parties. The two interest rates would be netted and the resulting difference would be multiplied by Alcoa’s equivalent percentage of the outstanding principal of the counterparty’s debt obligation as of December 31 of the year preceding the calculation date. This differential would be added to the cost of power in the period following the calculation date.

Alcoa has a forward contract to purchase $57 (C$58) to mitigate the foreign currency risk related to a Canadian-denominated loan due in 2014. All other foreign exchange contracts were entered into and settled within each of the periods presented.

Material Limitations

The disclosures with respect to commodity prices, interest rates, and foreign currency exchange risk do not take into account the underlying commitments or anticipated transactions. If the underlying items were included in the analysis, the gains or losses on the futures contracts may be offset. Actual results will be determined by a number of factors that are not under Alcoa’s control and could vary significantly from those factors disclosed.

Alcoa is exposed to credit loss in the event of nonperformance by counterparties on the above instruments, as well as credit or performance risk with respect to its hedged customers’ commitments. Although nonperformance is possible, Alcoa does not anticipate nonperformance by any of these parties. Contracts are with creditworthy counterparties and are further supported by cash, treasury bills, or

29

irrevocable letters of credit issued by carefully chosen banks. In addition, various master netting arrangements are in place with counterparties to facilitate settlement of gains and losses on these contracts.

Other Financial Instruments

The carrying values and fair values of Alcoa’s other financial instruments were as follows:

	March 31, 2013				December 31, 2012
	Carrying value		Fair value		Carrying value		Fair value
Cash and cash equivalents	$	1,555	$	1,555	$	1,861	$	1,861
Restricted cash		130		130		189		189
Noncurrent receivables		20		20		20		20
Available-for-sale securities		79		79		67		67
Short-term borrowings		51		51		53		53
Commercial paper		104		104		—		—
Long-term debt due within one year		1,025		1,266		465		477
Long-term debt, less amount due within one year		7,745		8,302		8,311		9,028

The following methods were used to estimate the fair values of other financial instruments:

Cash and cash equivalents, Restricted cash, Short-term borrowings, and Commercial paper.The carrying amounts approximate fair value because of the short maturity of the instruments. The fair value amounts for Cash and cash equivalents, Restricted cash, and Commercial paper were classified in Level 1, and Short-term borrowings were classified in Level 2.

Noncurrent receivables.The fair value of noncurrent receivables was based on anticipated cash flows, which approximates carrying value, and was classified in Level 2 of the fair value hierarchy.

Available-for-sale securities.The fair value of such securities was based on quoted market prices. These financial instruments consist of exchange-traded fixed income and equity securities, which are carried at fair value and were classified in Level 1 of the fair value hierarchy.

Long-term debt due within one year and Long-term debt, less amount due within one year. The fair value was based on quoted market prices for public debt and on interest rates that are currently available to Alcoa for issuance of debt with similar terms and maturities for non-public debt. At March 31, 2013 and December 31, 2012, $9,007 and $8,936, respectively, was classified in Level 1 of the fair value hierarchy for public debt and $561 and $569, respectively, was classified in Level 2 of the fair value hierarchy for non-public debt.

N. Subsequent Events – Management evaluated all activity of Alcoa and concluded that no subsequent events have occurred that would require recognition in the Consolidated Financial Statements or disclosure in the Notes to the Consolidated Financial Statements.

Report of Independent Registered Public Accounting Firm*

To the Shareholders and Board of Directors of Alcoa Inc.

We have reviewed the accompanying consolidated balance sheet of Alcoa Inc. and its subsidiaries (Alcoa) as of March 31, 2013, and the related statements of consolidated operations, consolidated comprehensive income, changes in consolidated equity, and consolidated cash flows for each of the three-month periods ended March 31, 2013 and 2012. These consolidated interim financial statements are the responsibility of Alcoa’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet as of December 31, 2012, and the related statements of consolidated operations, consolidated comprehensive (loss) income, changes in consolidated equity, and consolidated cash flows for the year then ended (not presented herein), and in our report dated February 15, 2013, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2012, is fairly stated in all material respects in relation to the consolidated balance sheet from which it has been derived.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

(dollars in millions, except per share amounts and ingot prices; production and shipments in thousands of metric tons [kmt])

Results of Operations

Selected Financial Data:

	First quarter ended March  31,
	2013		2012
Sales	$	5,833	$	6,006
Net income attributable to Alcoa common shareholders:	$	149	$	94
Diluted earnings per share attributable to Alcoa common shareholders:	$	0.13	$	0.09
Shipments of alumina (kmt)		2,457		2,293
Shipments of aluminum products (kmt)		1,224		1,295
Alcoa’s average realized price per metric ton of aluminum	$	2,398	$	2,433

Net income attributable to Alcoa was $149, or $0.13 per diluted share, in the 2013 first quarter compared with $94, or $0.09 per share, in the 2012 first quarter. The improvement of $55 was primarily the result of net productivity improvements, net favorable foreign currency movements, and higher realized prices for alumina, partially offset by lower realized prices for aluminum, unfavorable mix in the midstream segment, and a higher income tax provision, including discrete items.

Sales for the 2013 first quarter declined $173, or 3%, compared to the same period in 2012. The decrease was mainly caused by lower primary aluminum volumes, including those related to curtailed smelter capacity, unfavorable pricing in the midstream segment due to a decrease in metal prices, and a decline in realized prices for aluminum, driven by lower London Metal Exchange (LME) prices, somewhat offset by higher volumes in the Alumina and downstream segments.

Cost of goods sold (COGS) as a percentage of Sales was 83.1% in the 2013 first quarter compared with 84.9% in the 2012 first quarter. The percentage was positively impacted by net productivity improvements across all segments and net favorable foreign currency movements due to a stronger U.S. dollar, partially offset by the previously mentioned price impacts.

Selling, general administrative, and other expenses (SG&A) increased $10 in the 2013 first quarter compared to the corresponding period in 2012. The increase was primarily driven by incentive compensation expense, partly due to a discretionary reduction recorded in the 2012 first quarter related to 2011 for senior management, stock-based compensation expense, and consulting fees. SG&A as a percentage of Sales increased from 4.0% in the 2012 first quarter to 4.3% in the 2013 first quarter.

Restructuring and other charges in the 2013 first quarter were $7 ($5 after-tax), which were composed of the following components: $3 ($2 after-tax) for layoff costs, including a pension plan settlement charge related to previously separated employees and the voluntary separation of approximately 60 employees (Primary Metals segment), and a net charge of $4 ($3 after-tax) for other miscellaneous items.

Restructuring and other charges in the 2012 first quarter were $10 ($7 after-tax and noncontrolling interests), which were composed of the following components: $11 ($8 after-tax) for the layoff of approximately 220 employees (150 in the Primary Metals segment and 70 in the Engineered Products and Solutions segment), including $6 ($4 after-tax) for the layoff of an additional 150 employees related to the previously reported smelter curtailments in Spain; $1 ($1 after-tax) in other miscellaneous charges; and $2 ($2 after-tax and noncontrolling interests) for the reversal of a number of small layoff reserves related to prior periods.

Alcoa does not include Restructuring and other charges in the results of its reportable segments. The pretax impact of allocating such charges to segment results would have been as follows:

	First quarter ended March  31,
	2013		2012
Alumina	$	—	$	—
Primary Metals		—		5
Global Rolled Products		3		1
Engineered Products and Solutions		3		3
Segment total		6		9
Corporate		1		1
Total restructuring and other charges	$	7	$	10

As of March 31, 2013, all of the employees associated with the 2013 restructuring program, approximately 400 of the 800 employees associated with 2012 restructuring programs, and approximately 900 of the 1,475 employees associated with 2011 restructuring programs were separated. The remaining separations for the 2012 and 2011 restructuring programs are expected to be completed by the end of 2013.

In the 2013 first quarter, cash payments of less than $1, $7, and $4 were made against the layoff reserves related to the 2013, 2012, and 2011 restructuring programs, respectively.

Interest expense decreased $8, or 7%, in the 2013 first quarter compared to the corresponding period in 2012. The decrease was principally the result of a 7% lower average debt level due to the absence of outstanding borrowings for short-term liquidity purposes in the form of two term loans, a revolving credit facility, and a higher level of issued commercial paper.

Other income, net was $27 in the 2013 first quarter compared with $16 in the 2012 first quarter. The increase was mainly the result of a favorable change in mark-to-market aluminum derivative contracts ($29), partially offset by a higher equity loss ($10), mostly related to Alcoa’s share of expenses of the joint venture in Saudi Arabia, including smelter startup costs, and the absence of a gain recognized for the ineffective portion of aluminum cash flow hedges ($9).

The effective tax rate for the first quarter of 2013 and 2012 was 27.4% and 28.3%, respectively.

The rate for the 2013 first quarter differs from the U.S. federal statutory rate of 35% primarily due to a $19 discrete income tax benefit related to new U.S. tax legislation.

On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law and reinstated various expired or expiring temporary business tax provisions through 2013. Two specific temporary business tax provisions that expired in 2011 and impacted Alcoa are the look-through rule for payments between related controlled foreign corporations and the research and experimentation credit. The expiration of these two provisions resulted in Alcoa recognizing a higher income tax provision of $19 in 2012. As tax law changes are accounted for in the period of enactment, Alcoa recognized the previously mentioned discrete income tax benefit in the 2013 first quarter related to the 2012 tax year to reflect the extension of these provisions.

The rate for the 2012 first quarter differs from the U.S. federal statutory rate of 35% primarily due to foreign income taxed in lower rate jurisdictions.

Net income attributable to noncontrolling interests for the 2013 first quarter increased $16 compared with the corresponding period in 2012. The increase was primarily due to higher earnings at Alcoa World Alumina and Chemicals (AWAC), which is owned 60% by Alcoa and 40% by Alumina Limited. The improvement in earnings at AWAC was mainly driven by net favorable foreign currency movements, net productivity improvements, and higher realized prices, somewhat offset by input cost increases (see Alumina segment below).

Segment Information

On January 1, 2013, management revised the inventory-costing method used by certain locations within the Global Rolled Products and Engineered Products and Solutions segments, which affects the determination of the respective segment’s profitability measure, After-tax operating income (ATOI). Management made the change in order to improve

33

internal consistency and enhance industry comparability. This revision does not impact the consolidated results of Alcoa. Segment information for all prior periods presented was revised to reflect this change.

Alumina

	First quarter ended March 31,
	2013		2012
Alumina production (kmt)		3,994		4,153
Third-party alumina shipments (kmt)		2,457		2,293
Third-party sales	$	826	$	775
Intersegment sales		595		617
Total sales	$	1,421	$	1,392
ATOI	$	58	$	35

Alumina production decreased 4% in the 2013 first quarter compared with the corresponding period in 2012. The decline was largely due to lower production in Alcoa’s Atlantic refinery system as a result of management’s plan (initiated in the 2012 second quarter) to reduce annual production capacity by approximately 390 kmt. This decision was made to align production with smelter curtailments initiated at the beginning of 2012 and to reflect prevailing market conditions. Lower output at the Pinjarra and Kwinana refineries in Australia and the São Luís refinery in Brazil also contributed to the decrease in overall production.

Third-party sales for the Alumina segment rose 7% in the 2013 first quarter compared with the same period in 2012. The increase was primarily due to an improvement of 7% in volume and positive impacts from moving customer contracts to alumina index pricing and spot-pricing, both of which were somewhat offset by a decrease in contractual LME-based pricing.

Intersegment sales decreased 4% in the 2013 first quarter compared to the corresponding period in 2012 due to decreased demand from the Primary Metals segment.

ATOI for this segment increased 66% in the 2013 first quarter compared to the same period in 2012. The improvement was primarily the result of net favorable foreign currency movements due to a stronger U.S. dollar against the Australian dollar and Brazilian real, net productivity improvements, and the previously mentioned higher realized prices. These favorable impacts were somewhat offset by cost increases for natural gas, bauxite (mining costs such as labor, depreciation, fuel), and caustic soda.

In the second quarter of 2013, the continued shift towards the alumina price index and spot-pricing is expected to average 52% of third-party sales, while those still contractually-linked to the LME will follow a 30-day lag. Additionally, net productivity improvements are anticipated and production is expected to increase 150 kmt. ATOI will be negatively impacted by mining costs of approximately $20 related to Australia (crusher equipment move) and Suriname.

Primary Metals

	First quarter ended March 31,
	2013		2012
Aluminum production (kmt)		891		951
Third-party aluminum shipments (kmt)		705		771
Alcoa’s average realized price per metric ton of aluminum	$	2,398	$	2,433
Third-party sales	$	1,758	$	1,944
Intersegment sales		727		761
Total sales	$	2,485	$	2,705
ATOI	$	39	$	10

34

At March 31, 2013, Alcoa had 568 kmt of idle capacity on a base capacity of 4,227 kmt. In the 2013 first quarter, idle capacity decreased by 23 kmt compared to December 31, 2012, mostly due to the restart of a portion (27 kmt combined) of the capacity that was temporary curtailed in 2012 related to the Avilés and La Coruña smelters in Spain. This restart occurred in order to meet the requirements of the modified interruptibility regime in the Spanish power market (a detailed description follows).

In December 2012, the Spanish Government issued a Ministerial Order that modified the interruptibility regime previously in place in the Spanish power market. The interruptibility regime allows certain industrial customers who are willing to be subject to temporary interruptions in the supply of power to sell interruption rights to the high voltage transmission system operator. In January 2013, Alcoa applied for and was granted rights to sell interruption services under the modified regime from its San Ciprian, Avilés, and La Coruña smelters in Spain. The commitment is taken for a one-year period. Alcoa understands that the Spanish Government intends to notify the European Commission of the modification in the interruptibility regime for review under European state aid rules.

Aluminum production decreased 6% in the 2013 first quarter compared with the corresponding period in 2012. The decline was mainly caused by the absence of production at the Portovesme smelter (150 kmt-per-year) in Italy, which was fully curtailed at the end of 2012, and lower production at the two partially curtailed smelters in Spain (Avilés (35 kmt out of 93 kmt-per-year) and La Coruña (28 kmt out of 87 kmt-per-year)).

Third-party sales for the Primary Metals segment decreased 10% in the 2013 first quarter compared with the same period in 2012. The decline was mostly the result of lower volumes, including from the curtailed smelters in Italy and Spain, and a 1% decrease in average realized prices. The change in realized prices was driven by 6% lower average LME prices, mostly offset by higher regional premiums.

Intersegment sales declined 4% in the 2013 first quarter compared to the corresponding period in 2012, mainly as a result of decreased demand from the midstream and downstream businesses and a decline in realized prices, driven by the lower LME.

ATOI for this segment improved $29 in the 2013 first quarter compared to the same period in 2012. The increase was primarily due to lower costs for carbon, energy, and alumina, somewhat offset by higher costs for transportation, labor, and maintenance, among others; net productivity improvements; positive mix due to value-add products; and net favorable foreign currency movements due to a stronger U.S. dollar. These items were mostly offset by the previously mentioned decrease in realized prices, lower volumes, costs for a planned power plant maintenance outage at Rockdale, TX, and an equity loss related to startup costs of the smelter in Saudi Arabia.

In the second quarter of 2013, pricing is expected to continue to follow a 15-day lag on the LME and net productivity improvements are expected. There will be a significant maintenance outage, which occurs every four years, at the Anglesea power plant in Australia and a maintenance outage at the Warrick power plant in the United States resulting in a negative ATOI impact of approximately $25 combined. Additionally, Alcoa’s share of startup costs for the smelter in Saudi Arabia will negatively impact results.

Global Rolled Products

	First quarter ended March  31,
	2013		2012
Third-party aluminum shipments (kmt)		450		452
Third-party sales	$	1,779	$	1,845
Intersegment sales		51		44
Total sales	$	1,830	$	1,889
ATOI	$	81	$	102

35

Third-party sales for the Global Rolled Products segment decreased 4% in the 2013 first quarter compared with the corresponding period in 2012. The decline was principally the result of unfavorable pricing, due to a decrease in metal prices, and unfavorable product mix.

ATOI for this segment declined 21% in the 2013 first quarter compared to the same period in 2012. The decrease was principally related to unfavorable price/mix and higher input costs, mostly due to inflationary pressure, partially offset by net productivity improvements across all businesses.

In the second quarter of 2013, demand in the aerospace and automotive end markets is expected to remain strong, while the European and North American industrials and China markets will face pricing pressures. Also, net productivity improvements are anticipated.

Engineered Products and Solutions

	First quarter ended March 31,
	2013		2012
Third-party aluminum shipments (kmt)		55		58
Third-party sales	$	1,423	$	1,390
ATOI	$	173	$	157

Third-party sales for the Engineered Products and Solutions segment increased 2% in the 2013 first quarter compared with the corresponding period in 2012, mostly due to higher volumes related to the aerospace and industrial gas turbine end markets, somewhat offset by lower volumes related to the commercial transportation end market.

ATOI for this segment improved 10% in the 2013 first quarter compared to the same period in 2012, mainly the result of net productivity improvements across all businesses.

In the second quarter of 2013, the aerospace end market is expected to remain strong, while the non-residential building and construction end market will be mixed (decline in Europe, slight recovery in North America). Continued net productivity improvements and share gains through innovation are anticipated.

Reconciliation of ATOI to Consolidated Net Income Attributable to Alcoa

Items required to reconcile total segment ATOI to consolidated net income attributable to Alcoa include: the impact of LIFO inventory accounting; interest expense; noncontrolling interests; corporate expense (general administrative and selling expenses of operating the corporate headquarters and other global administrative facilities, along with depreciation and amortization on corporate-owned assets); restructuring and other charges; discontinued operations; and other items, including intersegment profit eliminations, differences between tax rates applicable to the segments and the consolidated effective tax rate, the results of the soft alloy extrusions business in Brazil, and other nonoperating items such as foreign currency transaction gains/losses and interest income.

The following table reconciles total segment ATOI to consolidated net income attributable to Alcoa:

	First quarter ended March  31,
	2013			2012
Total segment ATOI	$	351		$	304
Unallocated amounts (net of tax):
Impact of LIFO		(2	)		—
Interest expense		(75	)		(80	)
Noncontrolling interests		(21	)		(5	)
Corporate expense		(67	)		(64	)
Restructuring and other charges		(5	)		(7	)
Other		(32	)		(54	)
Consolidated net income attributable to Alcoa	$	149		$	94

36

The significant changes in the reconciling items between total segment ATOI and consolidated net income attributable to Alcoa for the 2013 first quarter compared with the corresponding period in 2012 consisted of:

• an increase in Noncontrolling interests, mainly due to higher earnings at AWAC, principally driven by net favorable foreign currency movements, net productivity improvements, and higher realized prices, somewhat offset by input cost increases; and

• a change in Other, mostly driven by a discrete income tax benefit related to the American Taxpayer Relief Act of 2012 ($19) and a net favorable change in mark-to-market derivative contracts ($16), somewhat offset by the difference between the consolidated effective tax rate and the estimated tax rates applicable to the segments.

Liquidity and Capital Resources

Cash From Operations

Cash used for operations was $70 in the 2013 three-month period compared with $236 in the same period of 2012. The improvement of $166 was principally due to higher operating results and lower pension contributions of $130, somewhat offset by a negative change associated with working capital of $130.

The lower pension contributions were principally driven by a change in minimum funding obligations for U.S. pension plans due to enacted legislation in 2012 (see below).

The major components of the negative change in working capital were as follows: an unfavorable change of $182 in receivables, primarily related to fewer sales of receivables, somewhat offset by a smaller increase in customer sales; a negative change of $29 in inventories; a favorable change of $50 in prepaid expenses and other current assets, mostly caused by the sale of excess carbon credits in Australia; a positive change of $177 in accounts payable, trade, principally the result of timing of payments; an unfavorable change of $136 in accrued expenses, largely attributable to a decrease in deferred revenue and a payment made to the Italian Government (see below); and a negative change of $10 in taxes, including income taxes.

In June 2012, Alcoa received formal notification from the Italian Government requesting a net payment of $310 (€250) related to a November 2009 European Commission decision on electricity pricing for smelters. Alcoa has been in discussions with the Italian Government regarding the timing of such payment. Alcoa commenced payment of the requested amount in five quarterly installments of $64 (€50), paying the first installment on October 31, 2012 and the second installment on March 27, 2013. It is possible that Alcoa may be required to accelerate payment or pay the remaining amount in a lump sum.

On July 6, 2012, the Moving Ahead for Progress in the 21^st Century Act (MAP-21) was signed into law by the United States government. MAP-21, in part, provides temporary relief for employers who sponsor defined benefit pension plans related to funding contributions under the Employee Retirement Income Security Act of 1974. Specifically, MAP-21 allows for the use of a 25-year average interest rate within an upper and lower range for purposes of determining minimum funding obligations instead of an average interest rate for the two most recent years, as was the case previously. This relief is expected to reduce Alcoa’s estimated minimum required pension funding by $225 to $250 in 2013.

On October 9, 2013, Alcoa World Alumina LLC, a majority-owned subsidiary of Alcoa, is expected to pay $42.5 to the plaintiff of a civil litigation matter pursuant to an October 2012 settlement agreement.

Financing Activities

Cash provided from financing activities was $47 in the 2013 three-month period, a decrease of $347 compared with $394 in the corresponding period of 2012.

The source of cash in the 2013 three-month period was primarily due to $625 in additions to debt, all of which was the result of borrowings under one existing and three new short-term facilities (see below), and net borrowings of $104 in commercial paper. These items were mostly offset by $639 in payments on debt, mainly related to $625 for the repayment of borrowings under one existing and three new short-term

37

facilities (see below) and $7 for previous borrowings on the loans supporting the Estreito hydroelectric power project in Brazil; $33 in dividends paid to shareholders; and net cash paid to noncontrolling interests of $10, most of which relates to Alumina Limited’s share of AWAC.

In the 2012 three-month period, the source of cash was primarily due to $730 in additions to debt, composed of $450 in borrowings under three new short-term facilities, mainly for working capital purposes, and $280 in new short-term loans to support the export operations of a subsidiary in Brazil; net borrowings of $51 in commercial paper; and net cash received from noncontrolling interests of $64, all of which relates to Alumina Limited’s share of AWAC. These items were partially offset by $414 in payments on debt, mostly related to $322 for the repayment of 6% Notes due 2012 as scheduled, $60 for the repayment of a portion of the new short-term loans to support the export operations of a subsidiary in Brazil, and $29 for previous borrowings on the loans supporting the São Luís refinery expansion, Juruti bauxite mine development, and Estreito hydroelectric power project in Brazil; and $33 in dividends paid to shareholders.

In the first quarter of 2013, Alcoa entered into three agreements, each with a different financial institution, for a $200 term loan, a $150 revolving credit facility, and a $75 revolving credit facility. The purpose of any borrowings under all three arrangements is to provide working capital and for other general corporate purposes.

The term loan was fully drawn on the same date as the agreement and was subject to an interest rate equivalent to the 1-month LIBOR plus a 1.5% margin. In March 2013, Alcoa and the lender agreed to terminate the term loan and entered into a revolving credit agreement, providing a $200 credit facility. As provided for in the terms of the revolving credit agreement, the outstanding term loan was automatically deemed to be an outstanding borrowing under the credit facility. This borrowing was subject to an interest rate equivalent to the 1-week LIBOR plus a 1.25% margin. As of March 31, 2013, the outstanding borrowing under this credit facility was repaid.

Additionally, in March 2013, Alcoa fully borrowed and repaid the $75 credit facility. This borrowing was subject to an interest rate equivalent to the 1-week LIBOR plus a 0.95% margin.

The $200 revolving credit facility expires in July 2013, the $150 revolving credit facility expires in February 2014, and the $75 revolving credit facility expires in December 2013. The covenants contained in all three arrangements are the same as Alcoa’s Five-Year Revolving Credit Agreement (see the Commercial Paper section of Note K to the Consolidated Financial Statements included in Alcoa’s 2012 Form 10-K).

As a result of an agreement between Alcoa and Alumina Limited in September 2012, Alcoa of Australia (part of the AWAC group of companies) will make minimum dividend payments to Alumina Limited of $100 in 2013. In the first quarter of 2013, Alcoa of Australia made $25 in such payments.

Alcoa’s cost of borrowing and ability to access the capital markets are affected not only by market conditions but also by the short- and long-term debt ratings assigned to Alcoa’s debt by the major credit rating agencies.

On April 11, 2013, Fitch Ratings (Fitch) affirmed the following ratings for Alcoa: long-term debt at BBB- and short-term debt at F3. Additionally, Fitch changed the current outlook from stable to negative.

Investing Activities

Cash used for investing activities was $285 in the 2013 three-month period compared with $350 in the 2012 three-month period, resulting in a decrease in cash used of $65.

In the 2013 three-month period, the use of cash was mainly due to $235 in capital expenditures, 34% of which related to growth projects, including the automotive expansion at the Davenport, IA fabrication plant, the aluminum-lithium capacity expansion at the Lafayette, IN plant, and the Estreito hydroelectric power project; and $121 in additions to investments, including equity contributions of $79 related to the aluminum complex joint venture in Saudi Arabia; slightly offset by a net change in restricted cash of $59, principally related to the release of funds to be used for capital expenditures of the automotive expansion at the Davenport, IA fabrication plant.

The use of cash in the 2012 three-month period was mainly due to $270 in capital expenditures, 33% of which related to growth projects, including the automotive expansion at the Davenport, IA fabrication plant and the Estreito hydroelectric power project; and $104 in additions to investments, including equity contributions of $93 related to the aluminum complex joint venture in Saudi Arabia.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

Litigation

As previously reported, before 2002, Alcoa purchased power in Italy in the regulated energy market and received a drawback of a portion of the price of power under a special tariff in an amount calculated in accordance with a published resolution of the Italian Energy Authority, Energy Authority Resolution n. 204/1999 (“204/1999”). In 2001, the Energy Authority published another resolution, which clarified that the drawback would be calculated in the same manner, and in the same amount, in either the regulated or unregulated market. At the beginning of 2002, Alcoa left the regulated energy market to purchase energy in the unregulated market. Subsequently, in 2004, the Energy Authority introduced regulation no. 148/2004 which set forth a different method for calculating the special tariff that would result in a different drawback for the regulated and unregulated markets. Alcoa challenged the new regulation in the Administrative Court of Milan and received a favorable judgment in 2006. Following this ruling, Alcoa continued to receive the power price drawback in accordance with the original calculation method, through 2009, when the European Commission declared all such special tariffs to be impermissible “state aid.” In 2010, the Energy Authority appealed the 2006 ruling to the Consiglio di Stato (final court of appeal). On December 2, 2011, the Consiglio di Stato ruled in favor of the Energy Authority and against Alcoa, thus presenting the opportunity for the energy regulators to seek reimbursement from Alcoa of an amount equal to the difference between the actual drawback amounts received over the relevant time period, and the drawback as it would have been calculated in accordance with regulation 148/2004. On February 23, 2012, Alcoa filed its appeal of the decision of the Consiglio di Stato (this appeal was subsequently withdrawn in March 2013). On March 26, 2012, Alcoa received a letter from the agency (Cassa Conguaglio per il Settore Eletrico (CCSE)) responsible for making and collecting payments on behalf of the Energy Authority demanding payment in the amount of approximately $110 million (€85 million), including interest. By letter dated April 5, 2012, Alcoa informed CCSE that it disputes the payment demand of CCSE since (i) CCSE was not authorized by the Consiglio di Stato decisions to seek payment of any amount, (ii) the decision of the Consiglio di Stato has been appealed (see above), and (iii) in any event, no interest should be payable. On April 29, 2012, Law No. 44 of 2012 (“44/2012”) came into effect, changing the method to calculate the drawback. On February 21, 2013, Alcoa received a revised request letter from CSSE demanding Alcoa’s subsidiary, Alcoa Trasformazioni S.r.l., make a payment in the amount of $97 million (€76 million), including interest, which reflects a revised calculation methodology by CCSE and represents the high end of the range of reasonably possible loss associated with this matter of $0 to $97 (€76). Alcoa has rejected that demand and has formally challenged it through an appeal before the Administrative Court on April 5, 2013. At this time, the Company is unable to reasonably predict an outcome for this matter.

Environmental Matters

As previously reported, representatives of various U.S. federal and state agencies and a Native American tribe, acting in their capacities as trustees for natural resources (Trustees), have asserted that Alcoa and Reynolds Metals Company (Reynolds) may be liable for loss or damage to such resources under federal and state law based on Alcoa’s and Reynolds’ operations at their Massena, New York and St. Lawrence, New York facilities. While formal proceedings had not been instituted at that time, the Company continued to actively investigate these claims. Pursuant to an agreement entered into with the Trustees in 1991, Alcoa and Reynolds had been working cooperatively with General Motors Corporation, which had been facing similar claims by the Trustees, to assess potential injuries to natural resources in the region. With the bankruptcy of General Motors in 2009, Motors Liquidation Company (MLC) took over General Motors’ liability in this matter. In September 2009, MLC notified Alcoa and the Trustees that it would no longer participate in the cooperative process. Alcoa and the Trustees agreed to continue to work together cooperatively without MLC to resolve Alcoa’s and Reynolds’ natural resources damages liability in this matter. In January 2011, the Trustees, representing the United States, the State of New York and the Mohawk tribe, and Alcoa reached an agreement in principle to resolve the natural resource damage claims. The parties have now finalized a proposed consent decree, which was filed with the United States District Court, Northern District of New York on March 27, 2013. The decree calls for Alcoa to pay approximately $20 million for environmental restoration and health and cultural programs for the Mohawk tribe. As of March 31, 2013, this amount was fully accrued on Alcoa’s Consolidated Balance Sheet. The public has 30 days to submit comments and the court may enter a final judgment thereafter.

As previously reported, Orange County Water District v. Sabic, et al, civil action 30-2008-00078246 (Superior Court of California, County of Orange) was filed against Alcoa Global Fasteners, Inc. on June 23, 2008. This matter alleges contamination or threatened contamination of a drinking water aquifer by Alcoa and others. Alcoa believes that it is not responsible for any contamination as alleged in the complaint or that if any liability were to be established, its liability would be insignificant. In 2012, Plaintiff Orange County Water District made a $2.5 million statutory settlement demand to Alcoa and other similar demands to certain other defendants. In January 2013, Alcoa and Plaintiff Orange County Water District reached a settlement in principle, subject to final documentation and court approval. The preliminary settlement amount does not exceed an amount previously reserved by Alcoa.
