&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;Derivative Instruments and Hedging Activities&amp;#8212;&lt;/b&gt;On July 1, 2010, Alcoa adopted changes to existing accounting requirements for embedded credit derivatives. Specifically, the changes clarify the scope exception regarding when embedded credit derivative features are not considered embedded derivatives subject to potential bifurcation and separate accounting. The adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On January 1, 2009, Alcoa adopted changes issued by the FASB to disclosures about derivative instruments and hedging activities. These changes require enhanced disclosures about an entity's derivative and hedging activities, including (i) how and why an entity uses derivative instruments, (ii) how derivative instruments and related hedged items are accounted for, and (iii) how derivative instruments and related hedged items affect an entity's financial position, financial performance, and cash flows. Other than the required disclosures (see the Derivatives section of Note X), the adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;&lt;/div&gt; &lt;/div&gt;</aa:DerivativeInstrumentsAndHedgingActivitiesPolicyTextBlock>

Liabilities are recorded when remediation costs are probable and can be reasonably estimated. The liability may include costs such as site investigations, consultant fees, feasibility studies, outside contractors, and monitoring expenses. Estimates are generally not discounted or reduced by potential claims for recovery. Claims for recovery are recognized as agreements are reached with third parties. The estimates also include costs related to other potentially responsible parties to the extent that Alcoa has reason to believe such parties will not fully pay their proportionate share.

The equity method is applied in situations where Alcoa has the ability to exercise significant influence, but not control, over the investee. Management reviews equity investments for impairment whenever certain indicators are present suggesting that the carrying value of an investment is not recoverable. This analysis requires a significant amount of judgment from management to identify events or circumstances indicating that an equity investment is impaired. The following items are examples of impairment indicators: significant, sustained declines in an investee's revenue, earnings, and cash flow trends; adverse market conditions of the investee's industry or geographic area; the investee's ability to continue operations measured by several items, including liquidity; and other factors. Once an impairment indicator is identified, management uses considerable judgment to determine if the impairment is other than temporary, in which case the equity investment is written down to its estimated fair value. An impairment that is other than temporary could significantly and adversely impact reported results of operations. &lt;/font&gt;&lt;/p&gt;&lt;/div&gt; &lt;/div&gt;</aa:EquityInvestmentsPolicyTextBlock>  <aa:EquityMethodInvestmentsAndInvestmentsInDebtAndMarketableEquitySecuritiesDisclosureTextBlock contextRef="Duration_1_1_2011_To_12_31_2011">&lt;div&gt; &lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;Equity Investments. &lt;/b&gt;As of December 31, 2011 and 2010, Equity investments included an interest in a project to develop a fully-integrated aluminum complex in Saudi Arabia (see below), hydroelectric power projects in Brazil (see Note N), a smelter operation in Canada (&lt;font class="_mt"&gt;25.05&lt;/font&gt;% of Pechiney Reynolds Quebec, Inc.), bauxite mining interests in Guinea (&lt;font class="_mt"&gt;45&lt;/font&gt;% of Halco Mining, Inc.) and Brazil (&lt;font class="_mt"&gt;18.2&lt;/font&gt;% of Minera&amp;#231;&amp;#227;o Rio do Norte S.A.), and a natural gas pipeline in Australia (see Note N). In 2011, 2010, and 2009, Alcoa received $&lt;font class="_mt"&gt;100&lt;/font&gt;, $&lt;font class="_mt"&gt;33&lt;/font&gt;, and $&lt;font class="_mt"&gt;56&lt;/font&gt;, respectively, in dividends from its equity investments. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In December 2009, Alcoa and Saudi Arabian Mining Company (known as "Ma'aden") entered into a &lt;font class="_mt"&gt;30&lt;/font&gt;-year joint venture shareholders' agreement (automatic extension for an additional&amp;nbsp;&lt;font class="_mt"&gt;20&lt;/font&gt; years, unless the parties agree otherwise or unless earlier terminated) setting forth the terms for the development, construction, ownership, and operation of an integrated bauxite mine, alumina refinery, aluminum smelter, and rolling mill, in Saudi Arabia. Specifically, the project to be developed by the joint venture will consist of: (i) a bauxite mine for the extraction of approximately&amp;nbsp;&lt;font class="_mt"&gt;4,000&lt;/font&gt; kmt of bauxite from the Al Ba'itha bauxite deposit near Quiba in the northern part of Saudi Arabia; (ii) an alumina refinery with an initial capacity of&amp;nbsp;&lt;font class="_mt"&gt;1,800&lt;/font&gt; kmt; (iii) a primary aluminum smelter with an initial capacity of&amp;nbsp;&lt;font class="_mt"&gt;740&lt;/font&gt; kmt; and (iv) a rolling mill with an initial capacity of&amp;nbsp;&lt;font class="_mt"&gt;380&lt;/font&gt; kmt. The refinery, smelter, and rolling mill will be constructed in an industrial area at Ras Al Khair (formerly Ras Az Zawr) on the east coast of Saudi Arabia. The facilities will use critical infrastructure, including power generation derived from reserves of natural gas, as well as port and rail facilities, developed by the government of Saudi Arabia. First production from the smelter and rolling mill is anticipated in 2013, and first production from the mine and refinery is expected in 2014. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;As initially conceived, the joint venture was to be owned &lt;font class="_mt"&gt;60&lt;/font&gt;% by Ma'aden with the other &lt;font class="_mt"&gt;40&lt;/font&gt;% being controlled by Alcoa through a special-purpose vehicle (SPV). Through this SPV arrangement, Alcoa and Aluminum Financing Limited would each have had a &lt;font class="_mt"&gt;20&lt;/font&gt;% economic interest in the joint venture. Aluminum Financing Limited's investment was in the form of subordinated, participating convertible notes issued by the SPV (the "Notes"), which had common equity rights in the SPV, and were to be converted into permanent equity at a future date based on certain conditions as defined in the underlying SPV agreement. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Following the signing of the joint venture shareholders' agreement, Alcoa paid Ma'aden $&lt;font class="_mt"&gt;80&lt;/font&gt; representing the initial investment of the &lt;font class="_mt"&gt;40&lt;/font&gt;% interest in the project. This investment was included in Additions to investments on the accompanying Statement of Consolidated Cash Flows. Aluminum Financing Limited's &lt;font class="_mt"&gt;50&lt;/font&gt;% share of the $80 was reflected as Convertible securities of subsidiary on the Consolidated Balance Sheet and in Contributions from noncontrolling interests on the accompanying Statement of Consolidated Cash Flows. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In March 2010, Alcoa and Ma'aden executed a supplement to the joint venture shareholders' agreement and modified the ownership structure such that the joint venture is now owned &lt;font class="_mt"&gt;74.9&lt;/font&gt;% by Ma'aden and &lt;font class="_mt"&gt;25.1&lt;/font&gt;% by Alcoa (Aluminum Financing Limited is no longer a participant). Concurrent with modifying the joint venture shareholders' agreement with Ma'aden, Alcoa entered into an agreement with Aluminum Financing Limited under which Alcoa redeemed the $&lt;font class="_mt"&gt;40&lt;/font&gt; in Notes, and Aluminum Financing Limited terminated all of its current and future interests in the SPV, for a payment of $&lt;font class="_mt"&gt;60&lt;/font&gt;. This $60 was included in Acquisitions of noncontrolling interests on the accompanying Statement of Consolidated Cash Flows. The difference between the redemption amount and the carrying value of the Notes was reflected as a reduction in Additional capital on the accompanying Consolidated Balance Sheet. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Going forward, Ma'aden and Alcoa will have put and call options, respectively, whereby Ma'aden can require Alcoa to purchase from Ma'aden, or Alcoa can require Ma'aden to sell to Alcoa, a &lt;font class="_mt"&gt;14.9&lt;/font&gt;% interest in the joint venture at the then fair market value. These options may only be exercised in a six-month window that opens five years after the Commercial Production Date (as defined in the joint venture shareholders' agreement) and, if exercised, must be exercised for the full 14.9% interest. In addition, Alcoa paid $&lt;font class="_mt"&gt;22&lt;/font&gt; and $&lt;font class="_mt"&gt;34&lt;/font&gt; to Ma'aden in 2011 and 2010, respectively, representing Alcoa's pro rata share of certain agreed upon pre-incorporation costs incurred by Ma'aden before formation of the joint venture. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Alcoa affiliate that holds Alcoa's interests in the smelting company and the rolling mill company is wholly owned by Alcoa, and the Alcoa affiliate that holds Alcoa's interests in the mining and refining company is wholly owned by Alcoa World Alumina and Chemicals (AWAC), which is owned &lt;font class="_mt"&gt;60&lt;/font&gt;% by Alcoa and &lt;font class="_mt"&gt;40&lt;/font&gt;% by Alumina Limited. Except in limited circumstances, Alcoa may not sell, transfer or otherwise dispose of or encumber or enter into any agreement in respect of the votes or other rights attached to its interests in the joint venture without Ma'aden's prior written consent. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;A number of Alcoa employees perform various types of services for the smelting, rolling mill, and refining and mining companies as part of the construction of the fully-integrated aluminum complex. At December 31, 2011, Alcoa has an outstanding receivable of $&lt;font class="_mt"&gt;25&lt;/font&gt; from the smelting, rolling mill, and refining and mining companies for labor and other employee-related expenses. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Capital investment in the project is expected to total approximately $&lt;font class="_mt"&gt;10,800&lt;/font&gt; (SAR&amp;nbsp;&lt;font class="_mt"&gt;40.5&lt;/font&gt; billion). As a result of the changes in the ownership structure described above, Alcoa's equity investment in the joint venture will be approximately $&lt;font class="_mt"&gt;1,100&lt;/font&gt; over a &lt;font class="_mt"&gt;four&lt;/font&gt;-year period, and Alcoa will be responsible for its pro rata share of the joint venture's project financing. During 2011 and 2010, Alcoa contributed $&lt;font class="_mt"&gt;249&lt;/font&gt; and $&lt;font class="_mt"&gt;160&lt;/font&gt;, respectively, towards the $1,100 commitment. As of December 31, 2011 and 2010, the carrying value of Alcoa's investment in this project, including the initial investment and respective pre-incorporation costs, was $&lt;font class="_mt"&gt;565&lt;/font&gt; and $&lt;font class="_mt"&gt;285&lt;/font&gt;, respectively. &lt;/font&gt;&lt;/p&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;/font&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In late 2010, the smelting and rolling mill companies entered into project financing totaling $&lt;font class="_mt"&gt;4,035&lt;/font&gt;, of which $&lt;font class="_mt"&gt;1,013&lt;/font&gt; represents Alcoa's share (the equivalent of Alcoa's &lt;font class="_mt"&gt;25.1&lt;/font&gt;% interest in the smelting and rolling mill companies). In conjunction with the financing, 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 &lt;font class="_mt"&gt;74.9&lt;/font&gt;% interest). Alcoa's guarantees for the smelting and rolling mill companies cover total debt service requirements of $&lt;font class="_mt"&gt;108&lt;/font&gt; in principal and up to a maximum of approximately $&lt;font class="_mt"&gt;50&lt;/font&gt; in interest per year (based on projected interest rates). At December 31, 2011 and 2010, the combined fair value of the guarantees was $&lt;font class="_mt"&gt;8&lt;/font&gt; and was included in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. 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. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;In late 2011, the refining and mining company entered into project financing totaling $&lt;font class="_mt"&gt;1,992&lt;/font&gt;, of which $&lt;font class="_mt"&gt;500&lt;/font&gt; represents AWAC's &lt;font class="_mt"&gt;25.1&lt;/font&gt;% 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 &lt;font class="_mt"&gt;74.9&lt;/font&gt;% interest). Alcoa's guarantees for the refining and mining company cover total debt service requirements of $&lt;font class="_mt"&gt;60&lt;/font&gt; in principal and up to a maximum of approximately $&lt;font class="_mt"&gt;25&lt;/font&gt; in interest per year (based on projected interest rates). At December 31, 2011, the combined fair value of the guarantees was $&lt;font class="_mt"&gt;4&lt;/font&gt;. 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. &lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Power for the refinery, smelter, and rolling mill will be supplied under a gas allocation from Saudi Aramco, based on authorization of the Ministry of Petroleum and Mineral Resources of Saudi Arabia (the "Ministry of Petroleum"). The letter authorizing the gas allocation provides for gas to be tolled and power to be supplied to the refinery, smelter, and rolling mill from an adjacent power and water desalination plant being constructed by a company ultimately owned by the government of Saudi Arabia, with the major tolling elements fixed at cost. The gas allocation is contingent on the finalization of implementing contractual arrangements and on the achievement of certain milestones, as defined in the joint venture shareholders' agreement, and includes possible penalties if the milestones are not met, including the following: (i) potential forfeiture of a $&lt;font class="_mt"&gt;350&lt;/font&gt; letter of credit required to be provided to the Ministry of Petroleum by Ma'aden (with Alcoa responsible for its pro rata share) to ensure completion of the refinery, (ii) potential forfeiture of the gas allocation if the smelter is not completed, (iii) a potential requirement for the smelter to allocate 275 kmt of aluminum to other entities determined by the Ministry of Petroleum if the rolling mill is not constructed, and (iv) under a new version of the gas allocation (issued in early 2011), forfeiture of a $&lt;font class="_mt"&gt;60&lt;/font&gt; letter of credit if certain auxiliary rolling facilities are not completed. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The parties subject to the joint venture shareholders' agreement and the SPV agreement may not sell, transfer, or otherwise dispose of, pledge, or encumber any interests in the joint venture or SPV until certain milestones have been met as defined in both agreements. Under the joint venture shareholders' agreement, upon the occurrence of an unremedied event of default by Alcoa, Ma'aden may purchase, or, upon the occurrence of an unremedied event of default by Ma'aden, Alcoa may sell, its interest for consideration that varies depending on the time of the default. Under the SPV agreement, upon the occurrence of an unremedied event of default by Alcoa, Alcoa's right to receive distributions will be suspended. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;Other Investments. &lt;/b&gt;As of December 31, 2011 and 2010, Other investments included $&lt;font class="_mt"&gt;92&lt;/font&gt; and $&lt;font class="_mt"&gt;93&lt;/font&gt;, respectively, in exchange-traded fixed income and equity securities, which are classified as available-for-sale and are carried at fair value with unrealized gains and losses recognized in other comprehensive income. Unrealized and realized gains and losses related to these securities were immaterial in 2011, 2010, and 2009. &lt;/font&gt;&lt;/p&gt;&lt;/div&gt; &lt;/div&gt;</aa:EquityMethodInvestmentsAndInvestmentsInDebtAndMarketableEquitySecuritiesDisclosureTextBlock>

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;Fair Value Accounting&lt;/b&gt;&amp;#8212;On January 1, 2011, Alcoa adopted changes issued by the FASB to disclosure requirements for fair value measurements. Specifically, the changes require a reporting entity to disclose, in the reconciliation of fair value measurements using significant unobservable inputs (Level 3), separate information about purchases, sales, issuances, and settlements (that is, on a gross basis rather than as one net number). These changes were applied to the disclosures in Note W and the Derivatives section of Note X to the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Effective January 1, 2010, Alcoa adopted changes issued by the FASB on January 21, 2010 to disclosure requirements for fair value measurements. Specifically, the changes require a reporting entity to disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and describe the reasons for the transfers. The changes also clarify existing disclosure requirements related to how assets and liabilities should be grouped by class and valuation techniques used for recurring and nonrecurring fair value measurements. The adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On June 30, 2009, Alcoa adopted changes issued by the FASB to fair value accounting. These changes provide additional guidance for estimating fair value when the volume and level of activity for an asset or liability have significantly decreased and includes guidance for identifying circumstances that indicate a transaction is not orderly. This guidance is necessary to maintain the overall objective of fair value measurements, which is that fair value is 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 under current market conditions. The adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On June 30, 2009, Alcoa adopted changes issued by the FASB to fair value disclosures of financial instruments. These changes require a publicly traded company to include disclosures about the fair value of its financial instruments whenever it issues summarized financial information for interim reporting periods. Such disclosures include the fair value of all financial instruments, for which it is practicable to estimate that value, whether recognized or not recognized in the statement of financial position; the related carrying amount of these financial instruments; and the method(s) and significant assumptions used to estimate the fair value. Other than including the required disclosures in Alcoa's Forms 10-Q, the adoption of these changes had no impact on the Consolidated Financial Statements (these disclosures were already required for annual reporting periods &amp;#8211; see the Other Financial Instruments section of Note X). &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On June 30, 2009, Alcoa adopted changes issued by the FASB to the recognition and presentation of other-than-temporary impairments. These changes amend existing other-than-temporary impairment guidance for debt securities to make the guidance more operational and to improve the presentation and disclosure of other-than-temporary impairments on debt and equity securities. The adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On October 1, 2009, Alcoa adopted changes issued by the FASB to fair value accounting for liabilities. These changes clarify existing guidance that in circumstances in which a quoted price in an active market for the identical liability is not available, an entity is required to measure fair value using either a valuation technique that uses a quoted price of either a similar liability or a quoted price of an identical or similar liability when traded as an asset, or another valuation technique that is consistent with the principles of fair value measurements, such as an income approach (e.g., present value technique). This guidance also states that both a quoted price in an active market for the identical liability and a quoted price for the identical liability when traded as an asset in an active market when no adjustments to the quoted price of the asset are required are Level 1 fair value measurements. The adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;&lt;/div&gt; &lt;/div&gt;</aa:FairValueAccountingPolicyTextBlock>  <aa:FairValueAssetsMeasuredOnRecurringBasisGainLossIncludedInCostOfGoodsSold xsi:nil="true" contextRef="Duration_1_1_2010_To_12_31_2010_aa_FairValueLevelThreeCategorizationByAssetTypeAxis_aa_FinancialInstrumentsMember" unitRef="Unit1" />

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;Litigation Matters. &lt;/b&gt;For asserted claims and assessments, liabilities are recorded when an unfavorable outcome of a matter is deemed to be probable and the loss is reasonably estimable. Management determines the likelihood of an unfavorable outcome based on many factors such as the nature of the matter, available defenses and case strategy, progress of the matter, views and opinions of legal counsel and other advisors, applicability and success of appeals processes, and the outcome of similar historical matters, among others. Once an unfavorable outcome is deemed probable, management weighs the probability of estimated losses, and the most reasonable loss estimate is recorded. If an unfavorable outcome of a matter is deemed to be reasonably possible, then the matter is disclosed and no liability is recorded. With respect to unasserted claims or assessments, management must first determine that the probability that an assertion will be made is likely, then, a determination as to the likelihood of an unfavorable outcome and the ability to reasonably estimate the potential loss is made. Legal matters are reviewed on a continuous basis to determine if there has been a change in management's judgment regarding the likelihood of an unfavorable outcome or the estimate of a potential loss. &lt;/font&gt;&lt;/p&gt;&lt;/div&gt; &lt;/div&gt;</aa:LitigationMattersPolicyTextBlock>  <aa:LossContingencyDamagesAwardedValue contextRef="Duration_1_11_2011_To_1_20_2011_aa_LitigationCaseTypeAxis_aa_ScrgBrownfieldRecoveryCorpEnergyAnswersCorporationOfPuertoRicoMember_us-gaap_LossContingenciesByNatureOfContingencyAxis_aa_BreachesOfWarrantyMember" unitRef="Unit1" decimals="-6">13000000</aa:LossContingencyDamagesAwardedValue>

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;Other&amp;#8212;&lt;/b&gt;On January 1, 2011, Alcoa adopted changes issued by the FASB to revenue recognition for multiple-deliverable arrangements. These changes require separation of consideration received in such arrangements by establishing a selling price hierarchy (not the same as fair value) for determining the selling price of a deliverable, which will be based on available information in the following order: vendor-specific objective evidence, third-party evidence, or estimated selling price; eliminate the residual method of allocation and require that the consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method, which allocates any discount in the arrangement to each deliverable on the basis of each deliverable's selling price; require that a vendor determine its best estimate of selling price in a manner that is consistent with that used to determine the price to sell the deliverable on a standalone basis; and expand the disclosures related to multiple-deliverable revenue arrangements. The adoption of these changes had no impact on the Consolidated Financial Statements, as Alcoa does not currently have any such arrangements with its customers. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On January 1, 2011, Alcoa adopted changes issued by the FASB to the classification of certain employee share-based payment awards. These changes clarify that there is not an indication of a condition that is other than market, performance, or service if an employee share-based payment award's exercise price is denominated in the currency of a market in which a substantial portion of the entity's equity securities trade and differs from the functional currency of the employer entity or payroll currency of the employee. An employee share-based payment award is required to be classified as a liability if the award does not contain a market, performance, or service condition. Prior to this guidance, the difference between the currency denomination of an employee share-based payment award's exercise price and the functional currency of the employer entity or payroll currency of the employee was not a factor considered by management when determining the proper classification of a share-based payment award. The adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On January 1, 2010, Alcoa adopted changes issued by the FASB to accounting for transfers of financial assets. These changes remove the concept of a qualifying special-purpose entity and remove the exception from the application of variable interest accounting to variable interest entities that are qualifying special-purpose entities; limit the circumstances in which a transferor derecognizes a portion or component of a financial asset; define a participating interest; require a transferor to recognize and initially measure at fair value all assets obtained and liabilities incurred as a result of a transfer accounted for as a sale; and require enhanced disclosure. The adoption of these changes had no impact on the Consolidated Financial Statements. In March 2010, management terminated the Company's accounts receivable securitization program (see Note U); had this program not been terminated, the adoption of these changes would have resulted in a $&lt;font class="_mt"&gt;250&lt;/font&gt; increase to both Receivables from customers and Short-term borrowings on the accompanying Consolidated Balance Sheet. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Effective January 1, 2010, Alcoa adopted changes issued by the FASB on February 24, 2010 to accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or available to be issued, otherwise known as "subsequent events." Specifically, these changes clarify that an entity that is required to file or furnish its financial statements with the SEC is not required to disclose the date through which subsequent events have been evaluated (see directly below). Other than the elimination of disclosing the date through which management has performed its evaluation for subsequent events (see Note Y), the adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On June 30, 2009, Alcoa adopted changes issued by the FASB to accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued, otherwise known as "subsequent events." Specifically, these changes set forth the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements, the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements, and the disclosures that an entity should make about events or transactions that occurred after the balance sheet date (see directly above). The adoption of these changes had no impact on the Consolidated Financial Statements as management already followed a similar approach prior to the adoption of this new guidance (see Note Y). &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px; font-size: 1px;"&gt;&amp;nbsp;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On January 1, 2009, Alcoa adopted changes issued by the FASB to the calculation of earnings per share. These changes state that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method (see Note S). The computation of earnings per share for all periods presented in the Consolidated Financial Statements was prepared in accordance with these changes. As a result, the adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On December 31, 2009, Alcoa adopted changes issued by the FASB to employers' disclosures about postretirement benefit plan assets. These changes provide guidance on an employer's disclosures about plan assets of a defined benefit pension or other postretirement plan. This guidance is intended to ensure that an employer meets the objectives of the disclosures about plan assets in an employer's defined benefit pension or other postretirement plan to provide users of financial statements with an understanding of the following: how investment allocation decisions are made; the major categories of plan assets; the inputs and valuation techniques used to measure the fair value of plan assets; the effect of fair value measurements using significant unobservable inputs on changes in plan assets; and significant concentrations of risk within plan assets. Other than the required disclosures (see Note W), the adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;
&lt;div class="MetaData"&gt;

&lt;div&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;Recently Issued Accounting Guidance.&lt;/b&gt; In May 2011, the FASB issued changes to conform existing guidance regarding fair value measurement and disclosure between GAAP and International Financial Reporting Standards. These changes both clarify the FASB's intent about the application of existing fair value measurement and disclosure requirements and amend certain principles or requirements for measuring fair value or for disclosing information about fair value measurements. The clarifying changes relate to the application of the highest and best use and valuation premise concepts, measuring the fair value of an instrument classified in a reporting entity's shareholders' equity, and disclosure of quantitative information about unobservable inputs used for Level 3 fair value measurements. The amendments relate to measuring the fair value of financial instruments that are managed within a portfolio; application of premiums and discounts in a fair value measurement; and additional disclosures concerning the valuation processes used and sensitivity of the fair value measurement to changes in unobservable inputs for those items categorized as Level 3, a reporting entity's use of a nonfinancial asset in a way that differs from the asset's highest and best use, and the categorization by level in the fair value hierarchy for items required to be measured at fair value for disclosure purposes only. These changes become effective for Alcoa on January 1, 2012. Other than the additional disclosure requirements, management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In June 2011, the FASB issued changes to the presentation of comprehensive income. These changes give an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements; the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity was eliminated. The items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income were not changed. Additionally, no changes were made to the calculation and presentation of earnings per share. These changes become effective for Alcoa on January 1, 2012. Other than the change in presentation, management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In December 2011, the FASB issued changes 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.

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;Goodwill and Other Intangible Assets&amp;#8212;&lt;/b&gt;On January 1, 2011, Alcoa adopted changes issued by the FASB to the testing of goodwill for impairment. These changes require an entity to perform all steps in the test for a reporting unit whose carrying value is zero or negative if it is more likely than not (more than &lt;font class="_mt"&gt;50&lt;/font&gt;%) that a goodwill impairment exists based on qualitative factors. This will result in the elimination of an entity's ability to assert that such a reporting unit's goodwill is not impaired and additional testing is not necessary despite the existence of qualitative factors that indicate otherwise. Based on the most recent impairment review of Alcoa's goodwill (2011 fourth quarter), the adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In September 2011, the FASB issued changes to the testing of goodwill for impairment. 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 &lt;font class="_mt"&gt;50&lt;/font&gt;%) that the fair value of a reporting unit 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. Under either option, the ultimate outcome of the goodwill impairment test should be the same. These changes are required to become effective for Alcoa for any goodwill impairment test performed on January 1, 2012 or later; however, early adoption is permitted. Alcoa elected to early adopt these changes in conjunction with management's annual review of goodwill in the fourth quarter of 2011 (see the Goodwill and Other Intangible Assets section of Note A above). The adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On January 1, 2009, Alcoa adopted changes issued by the FASB to accounting for intangible assets. These changes amend the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset in order to improve the consistency between the useful life of a recognized intangible asset outside of a business combination and the period of expected cash flows used to measure the fair value of an intangible asset in a business combination. The adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;&lt;/div&gt; &lt;/div&gt;</aa:RecentlyAdoptedAccountingGuidanceGoodwillAndOtherIntangibleAssetsPolicyTextBlock>

These changes establish the FASB Accounting Standards Codification&lt;/font&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="1"&gt;&lt;sup style="position: relative; bottom: 0.8ex; vertical-align: baseline;"&gt;TM&lt;/sup&gt;&lt;/font&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt; (Codification) as the source of authoritative accounting principles recognized by the FASB to be applied by nongovernmental entities in the preparation of financial statements in conformity with GAAP. Rules and interpretive releases of the Securities and Exchange Commission (SEC) under authority of federal securities laws are also sources of authoritative GAAP for SEC registrants. The FASB will no longer issue new standards in the form of Statements, FASB Staff Positions, or Emerging Issues Task Force Abstracts; instead the FASB will issue Accounting Standards Updates. Accounting Standards Updates will not be authoritative in their own right as they will only serve to update the Codification. These changes and the Codification itself do not change GAAP. Other than the manner in which new accounting guidance is referenced, the adoption of these changes had no impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;&lt;/div&gt; &lt;/div&gt;</aa:RecentlyAdoptedAccountingGuidancePolicyTextBlock>  <aa:RecentlyIssuedAccountingGuidancePolicyTextBlock contextRef="Duration_1_1_2011_To_12_31_2011">&lt;div&gt; &lt;div class="MetaData"&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;Recently Issued Accounting Guidance.&lt;/b&gt; In May 2011, the FASB issued changes to conform existing guidance regarding fair value measurement and disclosure between GAAP and International Financial Reporting Standards. These changes both clarify the FASB's intent about the application of existing fair value measurement and disclosure requirements and amend certain principles or requirements for measuring fair value or for disclosing information about fair value measurements. The clarifying changes relate to the application of the highest and best use and valuation premise concepts, measuring the fair value of an instrument classified in a reporting entity's shareholders' equity, and disclosure of quantitative information about unobservable inputs used for Level 3 fair value measurements. The amendments relate to measuring the fair value of financial instruments that are managed within a portfolio; application of premiums and discounts in a fair value measurement; and additional disclosures concerning the valuation processes used and sensitivity of the fair value measurement to changes in unobservable inputs for those items categorized as Level 3, a reporting entity's use of a nonfinancial asset in a way that differs from the asset's highest and best use, and the categorization by level in the fair value hierarchy for items required to be measured at fair value for disclosure purposes only. These changes become effective for Alcoa on January 1, 2012. Other than the additional disclosure requirements, management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In June 2011, the FASB issued changes to the presentation of comprehensive income. These changes give an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements; the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity was eliminated. The items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income were not changed. Additionally, no changes were made to the calculation and presentation of earnings per share. These changes become effective for Alcoa on January 1, 2012. Other than the change in presentation, management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top: 12px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In December 2011, the FASB issued changes 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. These changes become effective for Alcoa on January 1, 2013. Other than the additional disclosure requirements, management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;&lt;/div&gt;&lt;/div&gt; &lt;/div&gt;</aa:RecentlyIssuedAccountingGuidancePolicyTextBlock>  <aa:RecognitionOfIncomeCausedByPartialLiquidationsOfLowerCostLifoInventoryBaseGross contextRef="Duration_1_1_2009_To_12_31_2009" unitRef="Unit1" decimals="-6">175000000</aa:RecognitionOfIncomeCausedByPartialLiquidationsOfLowerCostLifoInventoryBaseGross>
