Accounting Changes and Error Corrections [Abstract] | |
Recently Adopted and Recently Issued Accounting Guidance | B. Recently Adopted and Recently Issued Accounting Guidance Adopted On January 1, 2015, Alcoa adopted changes issued by the Financial Accounting Standards Board (FASB) to reporting discontinued operations and disclosures of disposals of components of an entity. These changes require a disposal of a component to meet a higher threshold in order to be reported as a discontinued operation in an entity’s financial statements. The threshold is defined as a strategic shift that has, or will have, a major effect on an entity’s operations and financial results such as a disposal of a major geographical area or a major line of business. Additionally, the following two criteria have been removed from consideration of whether a component meets the requirements for discontinued operations presentation: (i) the operations and cash flows of a disposal component have been or will be eliminated from the ongoing operations of an entity as a result of the disposal transaction, and (ii) an entity will not have any significant continuing involvement in the operations of the disposal component after the disposal transaction. Furthermore, equity method investments now may qualify for discontinued operations presentation. These changes also require expanded disclosures for all disposals of components of an entity, whether or not the threshold for reporting as a discontinued operation is met, related to profit or loss information and/or asset and liability information of the component. The adoption of these changes had no impact on the Consolidated Financial Statements. This guidance will need to be considered in the event Alcoa initiates a disposal of a component. Issued In January 2015, the FASB issued changes to the presentation of extraordinary items. Such items are defined as transactions or events that are both unusual in nature and infrequent in occurrence, and, currently, are required to be presented separately in an entity’s income statement, net of income tax, after income from continuing operations. The changes eliminate the concept of an extraordinary item and, therefore, the presentation of such items will no longer be required. Notwithstanding this change, an entity will still be required to present and disclose a transaction or event that is both unusual in nature and infrequent in occurrence in the notes to the financial statements. These changes become effective for Alcoa on January 1, 2016. Management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements. In February 2015, the FASB issued changes to the analysis that an entity must perform to determine whether it should consolidate certain types of legal entities. These changes (i) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities, (ii) eliminate the presumption that a general partner should consolidate a limited partnership, (iii) affect the consolidation analysis of reporting entities that are involved with variable interest entities, particularly those that have fee arrangements and related party relationships, and (iv) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. These changes become effective for Alcoa on January 1, 2016. Management is currently evaluating the potential impact of these changes on the Consolidated Financial Statements. In April 2015, the FASB issued changes to the presentation of debt issuance costs. Currently, such costs are required to be presented as a noncurrent asset in an entity’s balance sheet and amortized into interest expense over the term of the related debt instrument. The changes require that debt issuance costs be presented in an entity’s balance sheet as a direct deduction from the carrying value of the related debt liability. The amortization of debt issuance costs remains unchanged. These changes become effective for Alcoa on January 1, 2016. Management has determined that the adoption of these changes will result in a decrease of approximately $60 to both Other noncurrent assets and Long-term debt, less amount due within one year on the accompanying Consolidated Balance Sheet. |

Restructuring and Other Charges Restructuring and other charges in the 2015 second quarter included $179 ($115 after-tax and noncontrolling interest) for exit costs related to decisions to permanently shut down and demolish a smelter and a power station (see below); $18 ($10 after-tax and noncontrolling interest) for the separation of approximately 120 employees (Alumina segment) and other charges related to the decisions to temporarily curtail both a portion of the capacity (443,000 metric-tons-per-year) at the refinery in Suriname and the remaining capacity (74,000 metric-tons-per-year) at the São Luís smelter in Brazil; $16 ($13 after-tax and noncontrolling interest) for layoff costs, including the separation of approximately 390 employees (210 in the Engineered Products and Solutions segment, 150 in the Primary Metals segment, and 30 in the Global Rolled Products segment); $10 ($7 after-tax and noncontrolling interest) related to post-closing adjustments associated with two December 2014 divestitures (see Note E); a net credit of $5 ($3 after-tax and noncontrolling interest) for other miscellaneous items; and $1 ($1 after-tax and noncontrolling interest) for the reversal of a few layoff reserves related to prior periods. In the 2015 six-month period, Restructuring and other charges included the aforementioned $179 ($115 after-tax and noncontrolling interest); $159 ($149 after-tax and noncontrolling interest) related to the March 2015 divestiture of a rolling mill in Russia and post-closing adjustments associated with three December 2014 divestitures (see Note E); $38 ($23 after-tax and noncontrolling interest) for the separation of approximately 800 employees (680 in the Primary Metals segment and 120 in the Alumina segment), supplier contract-related costs, and other charges associated with the aforementioned decisions to temporarily curtail certain capacity at the São Luís smelter and the refinery in Suriname; $29 ($21 after-tax and noncontrolling interest) for layoff costs, including the separation of approximately 600 employees (340 in the Engineered Products and Solutions segment, 150 in the Primary Metals segment, 60 in the Global Rolled Products segment, and 50 in Corporate); a net credit of $3 ($2 after-tax and noncontrolling interest) for other miscellaneous items; and $8 ($7 after-tax and noncontrolling interest) for the reversal of a number of small layoff reserves related to prior periods. In the second quarter of 2015, management approved the permanent shutdown and demolition of the Poços de Caldas smelter (capacity of 96,000 metric-tons-per-year) in Brazil and the Anglesea power station (includes the closure of a related coal mine) in Australia. The entire capacity at Poços de Caldas has been temporarily idled since May 2014 and the Anglesea power station is expected to be shut down by the end of August 2015. Demolition and remediation activities related to the Poços de Caldas smelter and the Anglesea power station will begin in 2016 and the second half of 2015, respectively, and are expected to be completed by the end of 2026 and 2020, respectively. The decision on the Poços de Caldas smelter was due to management’s conclusion that the smelter was no longer competitive as a result of challenging global market conditions for primary aluminum, which led to the initial curtailment, that have not dissipated and higher costs. For the Anglesea power station, the decision was made because a sale process did not result in a sale and there would be imminent operating costs and financial constraints related to this site in the remainder of 2015 and beyond, including significant costs to source coal from available resources, necessary maintenance costs, and a depressed outlook for forward electricity prices. The Anglesea power station previously supplied approximately 40 percent of the power needs for the Point Henry smelter, which was closed in August 2014. In the 2015 second quarter and six-month period, costs related to the shutdown actions included asset impairments of $86, representing the write-off of the remaining book value of all related properties, plants, and equipment; $11 for the layoff of approximately 100 employees (Primary Metals segment); and $82 in other exit costs. Additionally in the 2015 second quarter and six-month period, remaining inventories, mostly operating supplies and raw materials, were written down to their net realizable value resulting in a charge of $4 ($2 after-tax and noncontrolling interest), which was recorded in Cost of goods sold on the accompanying Statement of Consolidated Operations. The other exit costs of $82 represent $45 in asset retirement obligations and $29 in environmental remediation, both of which were triggered by the decisions to permanently shut down and demolish the aforementioned structures in Brazil and Australia (includes the rehabilitation of a related coal mine), and $8 in other related costs, including supplier and customer contract-related costs. In the second quarter and six-month period of 2014, Alcoa recorded Restructuring and other charges of $110 ($54 after-tax and noncontrolling interests) and $571 ($328 after-tax and noncontrolling interests), respectively. Restructuring and other charges in the 2014 second quarter included $107 ($51 after-tax and noncontrolling interest) for exit costs related to decisions to permanently shut down and demolish two smelters and two rolling mills (see below) and $3 ($3 after-tax) for other miscellaneous items, including layoff costs for the separation of approximately 75 employees (30 in the Global Rolled Products segment, 30 in Corporate, and 15 in Alcoa’s other three segments combined). In the 2014 six-month period, Restructuring and other charges included $443 ($240 after-tax and noncontrolling interest) for exit costs related to decisions to permanently shut down and demolish two smelters and two rolling mills (see below); $68 ($44 after-tax and noncontrolling interest) for the temporary curtailment of two smelters and a related production slowdown at one refinery (see below); $33 ($26 after-tax) for asset impairments related to prior capitalized costs for a modernization project at a smelter in Canada that is no longer being pursued; $17 ($11 after-tax) for layoff costs, including the separation of approximately 245 employees (115 in the Engineered Products and Solutions segment, 30 in the Global Rolled Products segment, 10 in the Alumina and Primary Metals segments combined, and 90 in Corporate); $17 ($11 after-tax) for other miscellaneous items; and $7 ($4 after-tax and noncontrolling interests) for the reversal of a number of small layoff reserves related to prior periods. In the 2014 first quarter, management approved the permanent shutdown and demolition of the remaining capacity (84,000 metric-tons-per-year) at the Massena East smelter in New York and the full capacity (190,000 metric-tons-per-year) at the Point Henry smelter in Australia. The capacity at Massena East was fully shut down by the end of March 2014 and the Point Henry smelter was fully shut down in August 2014. Demolition and remediation activities related to both the Massena East and Point Henry smelters began in late 2014 and are expected to be completed by the end of 2020 and 2018, respectively. The decisions on the Massena East and Point Henry smelters were part of a 15-month review of 460,000 metric tons of smelting capacity initiated by management in May 2013 for possible curtailment. Through this review, management determined that the remaining capacity of the Massena East smelter was no longer competitive and the Point Henry smelter had no prospect of becoming financially viable. Management also initiated the temporary curtailment of the remaining capacity (62,000 metric-tons-per-year) at the Poços de Caldas smelter and additional capacity (85,000 metric-tons-per-year) at the São Luís smelter, both in Brazil. These curtailments were completed by the end of May 2014. As a result of these curtailments, 200,000 metric-tons-per-year of production at the Poços de Caldas refinery was reduced by the end of June 2014. Also in the 2014 first quarter, management approved the permanent shutdown of Alcoa’s two rolling mills in Australia, Point Henry and Yennora. This decision was made due to the significant impact of excess can sheet capacity in both Australia and Asia. The two rolling mills had a combined can sheet capacity of 200,000 metric-tons-per-year and were closed by the end of 2014. Demolition and remediation activities related to the two rolling mills will begin mid 2015 and are expected to be completed by the end of 2018. In the second quarter and six-month period of 2014, costs related to the shutdown and curtailment actions included $4 and $137, respectively, for the layoff of approximately 1,830 employees (1,230 in the Primary Metals segment, 470 in the Global Rolled Products segment, 90 in the Alumina segment, and 40 in Corporate); accelerated depreciation of $91 and $150, respectively, related to the three facilities in Australia as they continued to operate during 2014; and $10 and $133, respectively, in other exit costs. Additionally, the costs in the 2014 six-month period also include asset impairments of $91, representing the write-off of the remaining book value of all related properties, plants, and equipment. Furthermore in the six-month period of 2014, remaining inventories, mostly operating supplies and raw materials, were written down to their net realizable value resulting in a charge of $34 ($20 after-tax and noncontrolling interest), which was recorded in Cost of goods sold on the accompanying Statement of Consolidated Operations. The other exit costs of $133 in the 2014 six-month period represent $55 in asset retirement obligations and $38 in environmental remediation, both of which were triggered by the decisions to permanently shut down and demolish the aforementioned structures in the United States and Australia, and $40 in other related costs, including supplier and customer contract-related costs. 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: Second quarter ended June 30, Six months ended June 30, 2015 2014 2015 2014 Alumina $ 10 $ — $ 17 $ 7 Primary Metals 173 84 198 415 Global Rolled Products 1 23 136 113 Engineered Products and Solutions 9 — 14 4 Segment total 193 107 365 539 Corporate 24 3 29 32 Total restructuring and other charges $ 217 $ 110 $ 394 $ 571 As of June 30, 2015, approximately 730 of the 1,500 employees associated with 2015 restructuring programs, approximately 2,460 of the 2,870 employees (previously 2,910 – updated to reflect employees accepting other positions within Alcoa and natural attrition) associated with 2014 restructuring programs, and 1,460 of the 1,530 employees associated with 2013 restructuring programs were separated. The remaining separations for the 2015, 2014, and 2013 restructuring programs are expected to be completed by the end of 2015. In the 2015 second quarter and six-month period, cash payments of $14 and $15, respectively, were made against the layoff reserves related to the 2015 restructuring programs, $6 and $56, respectively, were made against the layoff reserves related to the 2014 restructuring programs, and $2 and $5, respectively, were made against the layoff reserves related to the 2013 restructuring programs. Activity and reserve balances for restructuring charges were as follows: Layoff costs Other exit costs Total Reserve balances at December 31, 2013 $ 96 $ 42 $ 138 2014 Cash payments (191 ) (22 ) (213 ) Restructuring charges 259 194 453 Other* (66 ) (180 ) (246 ) Reserve balances at December 31, 2014 98 34 132 2015 Cash payments (76 ) (6 ) (82 ) Restructuring charges 61 88 149 Other* (23 ) (89 ) (112 ) Reserve balances at June 30, 2015 $ 60 $ 27 $ 87 * Other includes reversals of previously recorded restructuring charges and the effects of foreign currency translation. In the 2015 six-month period, Other for layoff costs also included a reclassification of $13 in pension and other postretirement benefits costs, as this obligation was included in Alcoa’s separate liability for pension and other postretirement benefit obligations (see Note M). Additionally in the 2015 six-month period, Other for other exit costs also included a reclassification of the following restructuring charges: $45 in asset retirement and $29 in environmental obligations, as these liabilities were included in Alcoa’s separate reserves for asset retirement obligations and environmental remediation (see Note G). In 2014, Other for layoff costs also included a reclassification of $26 in pension costs, as this obligation was included in Alcoa’s separate liability for pension obligations. Additionally in 2014, Other for other exit costs also included a reclassification of the following restructuring charges: $95 in asset retirement and $47 in environmental obligations, as these liabilities were included in Alcoa’s separate reserves for asset retirement obligations and environmental remediation. The remaining reserves are expected to be paid in cash during the second half of 2015, with the exception of approximately $20 to $25, which is expected to be paid over the next several years for ongoing site remediation work, lease termination costs, and special separation benefit payments. |

Business Combinations [Abstract] | |
Acquisitions and Divestitures | E. Acquisitions and Divestitures In March 2015, Alcoa completed the acquisition of an aerospace structural castings company, TITAL, for $204 (€188) in cash. TITAL, a privately held company with approximately 650 employees based in Germany, produces aluminum and titanium investment casting products for the aerospace and defense end markets. The purpose of this acquisition is to capture increasing demand for advanced jet engine components made of titanium, establish titanium-casting capabilities in Europe, and expand existing aluminum casting capacity. The assets and liabilities of this business were included within Alcoa’s Engineered Products and Solutions segment since the date of acquisition. Based on the preliminary allocation of the purchase price, goodwill of $123 was recorded for this transaction, none of which is estimated to be deductible for income tax purposes. The final allocation of the purchase price will be based on management’s best estimates, including a valuation of the assets acquired and liabilities assumed, which may result in the identification of other intangible assets, and other studies related to potential environmental and contingent liabilities. This transaction is subject to certain post-closing adjustments as defined in the purchase agreement. Also in March 2015, Alcoa signed a definitive agreement to acquire RTI International Metals, Inc. (RTI), a U.S. company publicly traded on the New York Stock Exchange under the ticker symbol “RTI.” Alcoa plans to purchase all outstanding shares of RTI common stock in a stock-for-stock transaction valued at approximately $1,100 (based on the $12.92 per share March 31, 2015 closing price of Alcoa’s common stock). Each issued and outstanding share of RTI common stock immediately prior to the completion of the transaction will be converted into the right to receive 2.8315 shares of Alcoa common stock (no fractional shares will be issued; a cash payment (without interest) in an amount reflecting prevailing market prices of Alcoa common stock on the New York Stock Exchange following the effective time of the merger will be made in lieu thereof). The exchange ratio is the quotient of a $41 per RTI common share acquisition price and the $14.48 per share March 6, 2015 closing price of Alcoa’s common stock. As of March 31, 2015, RTI had 30,794,405 shares of common stock outstanding. Additionally, Alcoa will assume approximately $500 in debt (see below) and acquire approximately $300 in cash (amounts are based on RTI’s Condensed Consolidated Balance Sheet at March 31, 2015). The outstanding shares of RTI common stock as of March 31, 2015 do not include certain compensatory RTI equity awards that will be granted the right to receive the exchange ratio as provided for in the merger agreement upon completion of the transaction. Additionally, the $500 of assumed debt relates to two outstanding series of RTI convertible senior notes, of which holders may elect to convert into shares of RTI common stock (13,070,774) upon meeting certain conditions in the related indenture prior to completion of the transaction. If such conversion occurs, these shares of RTI common stock also would be granted the right to receive the exchange ratio upon completion of the transaction. RTI is a global supplier of titanium and specialty metal products and services for the commercial aerospace, defense, energy, and medical device end markets. The purpose of this acquisition is to expand Alcoa’s range of titanium offerings and add advanced technologies and materials, primarily related to the aerospace end market. In 2014, RTI generated net sales of $794 and had approximately 2,600 employees. The proposed transaction is subject to customary conditions, including the receipt of all applicable regulatory approvals and RTI shareholder approval. All regulatory approvals were received in the second quarter of 2015, and on July 21, 2015, RTI’s shareholders approved the proposed transaction at RTI’s annual shareholders meeting. As a result, the transaction is expected to close on July 23, 2015, subject to the satisfaction of the remaining closing conditions set forth in the agreement. Subsequent to closing, RTI will be included within Alcoa’s Engineered Products and Solutions segment. In the 2015 six-month period, Alcoa completed the divestiture of an operation in Russia (see below) and had post-closing adjustments, as provided for in the respective purchase agreements, related to three divestitures completed in December 2014. The divestiture and post-closing adjustments combined resulted in net cash received of $30 and a net loss of $159 ($149 after-tax and noncontrolling interest), which was recorded in Restructuring and other charges (see Note D) on the accompanying Statement of Consolidated Operations. Two of these four divestitures remain subject to certain post-closing adjustments as defined in the respective purchase agreements. In March 2015, Alcoa completed the sale of a rolling mill located in Belaya Kalitva, Russia to a wholly-owned subsidiary of Stupino Titanium Company. While owned by Alcoa, the operating results and assets and liabilities of the rolling mill were included in the Global Rolled Products segment. The rolling mill generated sales of approximately $130 in 2014 and, at the time of divestiture, had approximately 1,870 employees. |

Commitments and Contingencies Disclosure [Abstract] | |
Contingencies and Commitments | G. Contingencies and Commitments Contingencies Litigation 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 (€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. The Administrative Court scheduled a hearing for December 19, 2013, which was subsequently postponed until April 17, 2014, and further postponed until June 19, 2014. On this date, the Administrative Court listened to Alcoa’s oral argument, and on September 2, 2014, rendered its decision. The Administrative Court declared the payment request of CCSE and the Energy Authority to Alcoa to be unsubstantiated based on the 148/2004 resolution with respect to the January 19, 2007 through November 19, 2009 timeframe. On December 18, 2014, the CCSE and the Energy Authority appealed the Administrative Court’s September 2, 2014 decision; however, a date for the hearing has not been scheduled. 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 complied 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 was to be based on a calculation 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 (see below). Prior to 2012, Alcoa was involved in other legal proceedings related to this matter that separately sought the annulment of the EC’s July 2006 decision to open an investigation alleging that such decision did not follow the applicable procedural rules and requested injunctive relief to suspend the effectiveness of the EC’s November 19, 2009 decision. However, the decisions by the General Court, and subsequent appeals to the European Court of Justice, resulted in the denial of these remedies. 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) for 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 October 17, 2013, the European Court of Justice ordered Italy to so collect). On September 27, 2012, Alcoa received a request for payment in full of the $310 (€250) by October 31, 2012. Following discussions with the Italian Government regarding the timing of such payment, Alcoa paid the requested amount in five quarterly installments of $69 (€50) beginning in October 2012 through December 2013. Notwithstanding the payments made, 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 loss, which is $176 (€159) to $337 (€303), remains the $176 (€159) recorded in 2009 (the U.S. dollar amount reflects the effects of foreign currency movements since 2009). Alcoa no longer has a reserve for this matter; instead, Alcoa has a noncurrent asset reflecting the excess of the total of the five payments made to the Italian Government over the reserve recorded in 2009. At June 30, 2015, the noncurrent asset was $102 (€91) (this does not include the $59 (€53) for amounts owed by the Italian Government to Alcoa mentioned above). On October 16, 2014, Alcoa received notice from the General Court of the EU that its April 19, 2010 appeal of the EC’s November 19, 2009 decision was denied. On December 27, 2014, Alcoa filed an appeal of the General Court’s October 16, 2014 ruling to the European Court of Justice. On April 22, 2015, Alcoa was notified that the EC filed its response to Alcoa’s appeal, and on April 30, 2015, Alcoa filed an application with the European Court of Justice seeking permission to file a reply to the EC’s response. This application was denied; therefore, Alcoa requested an oral hearing in this matter. A decision by the European Court of Justice in this matter could take up to two years or longer. 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. Over a portion of this time, a long-term solution was not able to be reached related to the Fusina smelter, therefore, in May 2010, Alcoa and the Italian Government agreed to a temporary idling of the Fusina smelter. As of September 30, 2010, the Fusina smelter was fully curtailed (44,000 metric-tons-per-year). For the Portovesme smelter, Alcoa executed a new power agreement effective September 1, 2010 through December 31, 2012, replacing the short-term, market-based power contract that was in effect since early 2010. This new agreement along with interruptibility rights (i.e. compensation for power interruptions when grids are overloaded) granted to Alcoa for the Portovesme smelter provided additional time to negotiate a long-term solution (the EC had previously determined that the interruptibility rights were not considered state aid). 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 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). As of December 31, 2012, the Portovesme smelter was fully curtailed (150,000 metric-tons-per-year). In June 2013 and August 2014, Alcoa decided to permanently shut down and demolish the Fusina and Portovesme smelters, respectively, due to persistent uneconomical conditions. Environmental Matters Alcoa participates in environmental assessments and cleanups at more than 100 locations. 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 environmental remediation when a cleanup program becomes probable and the costs 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. 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 $574 and $543 at June 30, 2015 and December 31, 2014 (of which $53 and $70 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 2015 second quarter and six-month period, the remediation reserve was increased by $45 and $53, respectively. The change in the second quarter of 2015 was due to a charge of $29 related to the planned demolition of the Poços de Caldas smelter and the Anglesea power station (see Note D), a charge of $11 related to the Mosjøen location (see below), and a net charge of $5 associated with a number of other sites. In the 2015 six-month period, the change was due to the previously mentioned charges of $29 and $11, a charge of $7 related to the Portovesme location (see below), and a net charge of $6 associated with a number of other sites. The changes to the remediation reserve in the 2015 second quarter and six-month period, except for the charge of $29, were recorded in Cost of goods sold on the accompanying Statement of Consolidated Operations. Payments related to remediation expenses applied against the reserve were $10 and $16 in the 2015 second quarter and six-month period, respectively. These amounts include expenditures currently mandated, as well as those not required by any regulatory authority or third party. In the 2015 second quarter and six-month period, the change in the reserve also reflects an increase of $1 and a decrease of $6, respectively, 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— Sherwin, TX— East St. Louis, IL— Fusina and Portovesme, Italy— In December 2009, Trasformazioni and Ligestra reached an initial agreement for settlement of the liabilities related to Fusina while negotiations continued related to Portovesme (see below). The agreement outlined 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 was 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 in 2009 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. In October 2013, the MOE approved the project submitted by Alcoa, resulting in no adjustment to the reserve. In January 2014, in anticipation of Alcoa reaching a final administrative agreement with the MOE, Alcoa and Ligestra entered into a final agreement related to Fusina for allocation of payments to the MOE for emergency action and natural resource damages and the costs for the approved soil remediation project. The agreement resulted in Ligestra assuming 50% to 80% of all payments and remediation costs. On February 27, 2014, Alcoa and the MOE reached a final administrative agreement for conduct of work. This agreement includes both a soil and groundwater remediation project estimated to cost $33 (€24) and requires payments of $25 (€18) to the MOE for emergency action and natural resource damages. The remediation projects are slated to begin in the second half of 2015. Based on the final agreement with Ligestra, Alcoa’s share of all costs and payments is $17 (€12), of which $9 (€6) related to the damages will be paid annually over a 10-year period, which began in April 2014, and was previously fully reserved. Separately, in 2009, due to additional information derived from the site investigations conducted at Portovesme, Alcoa increased the reserve by $3. 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. In November 2013, the MOE rejected the proposed soil remediation project and requested a revised project be submitted. In May 2014, Trasformazioni and Ligestra submitted a revised soil remediation project that addressed certain stakeholders’ concerns. Alcoa increased the reserve by $3 in 2014 to reflect the estimated higher costs associated with the revised soil remediation project, as well as current operating and maintenance costs of the Portovesme site. In October 2014, the MOE required a further revised project be submitted to reflect the removal of a larger volume of contaminated soil than what had been proposed, as well as design changes for the cap related to the remaining contaminated soil left in place and the expansion of an emergency containment groundwater pump and treatment system that was previously installed. Trasformazioni and Ligestra submitted the further revised soil remediation project in February 2015. As a result, Alcoa increased the reserve by $7 in the 2015 first quarter to reflect the increase in the estimated costs of the project. The ultimate outcome of this matter may result in a change to the existing reserve for Portovesme. Baie Comeau, Quebec, Canada— Mosjøen, Norway— In the second quarter of 2015, the NEA notified Alcoa that the revised project was approved and required submission of the final project design before issuing a final order. Alcoa completed and submitted the final project design, which identified a need to stabilize the related wharf structure to allow for the sediment dredging in the harbor. As a result, Alcoa increased the reserve for Mosjøen by $11 in the 2015 second quarter to reflect the estimated cost of the wharf stabilization. In June 2015, the NEA issued a final order approving the project as well as the final project design. Project construction is expected to begin in the second half of 2015 and be completed by the end of 2017. Other In September 2010, following a corporate income tax audit covering the 2003 through 2005 tax years, an assessment was received as a result of Spain’s tax authorities disallowing certain interest deductions claimed by a Spanish consolidated tax group owned by the Company. An appeal of this assessment in Spain’s Central Tax Administrative Court by the Company was denied in October 2013. In December 2013, the Company filed an appeal of the assessment in Spain’s National Court. Additionally, following a corporate income tax audit of the same Spanish tax group for the 2006 through 2009 tax years, Spain’s tax authorities issued an assessment in July 2013 similarly disallowing certain interest deductions. In August 2013, the Company filed an appeal of this second assessment in Spain’s Central Tax Administrative Court, which was denied in January 2015. The Company filed an appeal of this second assessment in Spain’s National Court in March 2015. The combined assessments (remeasured for a tax rate change enacted in November 2014) total $253 (€228). The Company believes it has meritorious arguments to support its tax position and intends to vigorously litigate the assessments through Spain’s court system. However, in the event the Company is unsuccessful, a portion of the assessments may be offset with existing net operating losses available to the Spanish consolidated tax group. Additionally, it is possible that the Company may receive similar assessments for tax years subsequent to 2009. At this time, the Company is unable to reasonably predict an outcome for this matter. 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 received $41 (R$82) in cash in May 2012. 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. AWAB presented defense of its claim to the RFB on April 8, 2013. If AWAB is successful in this 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 $50 (R$155), 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 $55 (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. Between 2000 and 2002, Alcoa Alumínio (Alumínio) sold approximately 2,000 metric tons of metal per month from its Poços de Caldas facility, located in the State of Minas Gerais (the “State”), to Alfio, a customer also located in the State. Sales in the State were exempted from value-added tax (VAT) requirements. Alfio subsequently sold metal to customers outside of the State, but did not pay the required VAT on those transactions. In July 2002, Alumínio received an assessment from State auditors on the theory that Alumínio should be jointly and severally liable with Alfio for the unpaid VAT. In June 2003, the administrative tribunal found Alumínio liable, and Alumínio filed a judicial case in the State in February 2004 contesting the finding. In May 2005, the Court of First Instance found Alumínio solely liable, and a panel of a State appeals court confirmed this finding in April 2006. Alumínio filed a special appeal to the Superior Tribunal of Justice (STJ) in Brasilia (the federal capital of Brazil) later in 2006. In 2011, the STJ (through one of its judges) reversed the judgment of the lower courts, finding that Alumínio should neither be solely nor jointly and severally liable with Alfio for the VAT, which ruling was then appealed by the State. In August 2012, the STJ agreed to have the case reheard before a five-judge panel. A decision from this panel is pending, but additional appeals are likely. At June 30, 2015, the assessment totaled $41 (R$130), including penalties and interest. While the Company believes it has meritorious defenses, the Company is unable to reasonably predict an outcome. 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 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) and has been funded through a combination of equity contributions by the joint venture partners and project financing by the joint venture, which has been guaranteed by both partners (see below). Both the equity contributions and the guarantees of the project financing are based on the joint venture’s partners’ ownership interests. Originally, it was estimated that Alcoa’s total equity investment in the joint venture would be approximately $1,100, of which Alcoa has contributed $961, including $5 and $9 in the 2015 second quarter and six-month period, respectively. Based on changes to both the project’s capital investment and equity and debt structure from the initial plans, the estimated $1,100 equity contribution may be reduced. As of June 30, 2015 and December 31, 2014, the carrying value of Alcoa’s investment in this project was $952 and $983, respectively. The smelting and rolling mill companies have project financing totaling $4,515, of which $1,133 represents Alcoa’s share (the equivalent of Alcoa’s 25.1% interest in the smelting and rolling mill companies). 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 2017 and 2020 for the smelting company and 2018 and 2021 for the rolling mill company (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 $176 in principal and up to a maximum of approximately $50 in interest per year (based on projected interest rates). At June 30, 2015 and December 31, 2014, the combined fair value of the guarantees was $8, which was included in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. The mining and refining company has project financing totaling $2,232, of which $560 represents Alcoa World Alumina and Chemical’s (AWAC) 25.1% interest in the mining and refining company. In conjunction with the financings, Alcoa, on behalf of AWAC, issued guarantees to the lenders in the event that the mining and refining company defaults on its debt service requirements through 2019 and 2024 (Ma’aden issued similar guarantees for its 74.9% interest). Alcoa’s guarantees for the mining and refining company cover total debt service requirements of $120 in principal and up to a maximum of approximately $30 in interest per year (based on projected interest rates). At June 30, 2015 and December 31, 2014, the combined fair value of the guarantees was $3 and $4, respectively, which 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. Alumínio, a wholly-owned subsidiary of Alcoa, is a participant in four consortia that each owns a hydroelectric power project in Brazil. One of these projects is known as Estreito, which 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 $1,650 (R$5,170) and Alumínio’s share is approximately $420 (R$1,320). As of June 30, 2015, approximately $400 (R$1,270) of Alumínio’s commitment was expended on the project. 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 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 required Alcoa to contribute $39 (A$40), all of which was made through December 2014. Following the completion of the three-year equity call plan in December 2014, the consortium initiated a new equity call plan to further improve its capitalization structure. This plan requires Alcoa to contribute $30 (A$36) through mid 2016, of which $9 (A$12) was made through June 30, 2015, including $5 (A$6) and $8 (A$11) in the 2015 second quarter and six-month period, respectively. In addition to its equity ownership, Alcoa has an agreement to purchase gas transmission services from the DBNGP. At June 30, 2015, Alcoa has an asset of $280 (A$364) 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 $400 (A$520) as of June 30, 2015. On April 8, 2015, Alcoa’s majority-owned subsidiary, Alcoa of Australia Limited (AofA), which is part of AWAC, secured a new 12-year gas supply agreement to power its three alumina refineries in Western Australia beginning in July 2020. This agreement was conditional on the completion of a third-party acquisition of the related energy assets from the current owner, which occurred in the 2015 second quarter. The terms of AofA’s gas supply agreement require a prepayment of $500 to be made in two installments. The first installment of $300 was made at the time of the completion of the third-party acquisition in June and was reflected in Other noncurrent assets on the accompanying Consolidated Balance Sheet. The second installment of $200 will be made in January 2016. |

In the 2014 six-month period, basic average shares outstanding and diluted average shares outstanding were the same because the effect of potential shares of common stock was anti-dilutive since Alcoa generated a net loss. As a result, 33 million share equivalents related to convertible notes (see below), 19 million stock awards, and 31 million stock options were not included in the computation of diluted EPS. Had Alcoa generated sufficient net income in the 2014 six-month period, 33 million, 10 million, and 6 million potential shares of common stock related to the convertible notes, stock awards, and stock options, respectively, would have been included in diluted average shares outstanding. In the first quarter of 2014, holders of convertible notes exercised their option to convert the notes into 89 million shares of Alcoa common stock. As a result, for the 2014 second quarter, these 89 million shares were outstanding for the entire period and were included in both basic and diluted average shares outstanding. For the 2014 six-month period, these 89 million shares were outstanding for a portion of the period equivalent to a weighted average of 56 million shares. The 56 million shares were included in both basic and diluted average shares outstanding for the 2014 six-month period. For the portion of the 2014 six-month period that the notes were still outstanding debt, a weighted average of the 89 million share equivalents (33 million) would have been included only in the diluted average shares outstanding if their effect was dilutive. Options to purchase 13 million and 3 million shares of common stock at a weighted average exercise price of $14.78 and $16.24 per share were outstanding as of June 30, 2015 and 2014, 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. In March 2015, Alcoa entered into an agreement to acquire RTI (see Note E). The purchase price will be paid in Alcoa common stock equivalent to approximately 90 million shares as of June 30, 2015. |

Income Taxes | K. Income Taxes The rate for the 2015 second quarter differs from the U.S. federal statutory rate of 35% primarily due to a $21 favorable impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized (partial reversal of the 2015 first quarter impact). The rate for the 2014 second quarter differs from the U.S. federal statutory rate of 35% primarily due to the U.S. tax impact of deemed distributions from otherwise lower tax rate foreign jurisdictions and operational income of certain foreign subsidiaries taxed in lower rate jurisdictions, mostly offset by a $20 favorable impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized (partial reversal of the 2014 first quarter impact). The effective tax rate for the 2015 and 2014 six-month periods was 39.4% (provision on income) and 1.5% (provision on a loss), respectively. The rate for the 2015 six-month period differs from the U.S. federal statutory rate of 35% primarily due to a $34 net discrete income tax charge as described below, a loss on the sale of a rolling mill in Russia (see Note E) for which no tax benefit was recognized, and a $14 unfavorable impact related to the interim period treatment of losses in certain foreign jurisdictions for which no tax benefit was recognized (impact is expected to reverse by the end of 2015), somewhat offset by foreign income taxed in lower rate jurisdictions. In the first quarter of 2015, AWAC, a joint venture owned 60% by Alcoa and 40% by Alumina Limited (Alcoa consolidates AWAC for financial reporting purposes), recognized an $83 discrete income tax charge (increased to $85 in the 2015 second quarter) for a valuation allowance on certain deferred tax assets, which were related mostly to employee benefits and tax loss carryforwards. Alcoa also had a $50 deferred tax liability (increased to $51 in the 2015 second quarter) related to its 60%-share of these deferred tax assets that was written off as a result of the valuation allowance recognized by AWAC. The rate for the 2014 six-month period differs (by (36.5) percentage points) from the U.S. federal statutory rate of 35% primarily due to a $36 unfavorable impact related to the interim period treatment of operational losses in certain foreign jurisdictions for which no tax benefit was recognized (impact reversed by the end of 2014). |

Receivables As of June 30, 2015 and December 31, 2014, the deferred purchase price receivable was $401 and $356, respectively, 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 collected under this program since its inception was $21,320 and $20,669, respectively. Alcoa services the customer receivables for the financial institutions at market rates; therefore, no servicing asset or liability was recorded. |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivatives and Other Financial Instruments | N. Derivatives and Other Financial Instruments Fair Value 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 (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (ii) 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. 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. A number of Alcoa’s aluminum, energy, and foreign exchange contracts are classified as Level 1 and an interest rate contract is classified as Level 2 under the fair value hierarchy. These energy, foreign exchange, and interest rate contracts are not material to Alcoa’s Consolidated Financial Statements for all periods presented except as follows for a foreign exchange contract. Alcoa had a forward contract to purchase $231 (R$543) to mitigate the foreign currency risk associated with a potential future transaction denominated in Brazilian reais. This contract expired on March 31, 2014 and a loss of $4 was recognized in Other expenses, net on the accompanying Statement of Consolidated Operations in the 2014 first quarter. For the aluminum contracts classified as Level 1, the total fair value of derivatives recorded as assets and liabilities was $2 and $56 and $2 and $31 at June 30, 2015 and December 31, 2014, respectively. These contracts were entered into to either hedge forecasted sales or purchases of aluminum in order to manage the associated aluminum price risk. Certain of these contracts are designated as hedging instruments, either fair value or cash flow, and the remaining are not designated as such. Combined, Alcoa recognized a net gain of $15 and $41 in the 2015 second quarter and six-month period, respectively, and a net gain of $8 and a net loss of $17 in the 2014 second quarter and six-month period, respectively, in Sales on the accompanying Statement of Consolidated Operations related to these aluminum contracts. In addition to the Level 1 and 2 derivative instruments described above, Alcoa has nine derivative instruments classified as Level 3 under the fair value hierarchy. These instruments are composed of seven embedded aluminum derivatives, an energy contract, and an embedded credit derivative, all of which relate to energy supply contracts associated with eight smelters and three refineries. Five of the embedded aluminum derivatives and the energy contract were designated as cash flow hedging instruments and two of the embedded aluminum derivatives and the embedded credit derivative were not designated as hedging instruments. The following section describes the valuation methodologies used by Alcoa to measure its Level 3 derivative instruments at fair value. Derivative instruments classified as Level 3 in the fair value hierarchy represent those in which management has used at least one significant unobservable input in the valuation model. Alcoa uses a discounted cash flow model to fair value all Level 3 derivative instruments. Where appropriate, the description below includes the key inputs to those models and any significant assumptions. These valuation models are reviewed and tested at least on an annual basis. Inputs in the valuation models for Level 3 derivative instruments are composed of the following: (i) quoted market prices (e.g., aluminum prices on the 10-year London Metal Exchange (LME) forward curve and energy prices), (ii) significant other observable inputs (e.g., information concerning time premiums and volatilities for certain option type embedded derivatives and regional premiums for aluminum contracts), and (iii) unobservable inputs (e.g., aluminum and energy prices beyond those quoted in the market). For periods beyond the term of quoted market prices for aluminum, Alcoa estimates the price of aluminum by extrapolating the 10-year LME forward curve. Additionally, 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 unobservable in one period becomes observable in a subsequent period, the related asset or liability would be transferred to the appropriate classification (Level 1 or 2) in the period of such change (there were no such transfers in the periods presented). Alcoa has embedded derivatives in two power contracts that index the price of power to the LME price of aluminum. Additionally, in late 2014, Alcoa renewed three power contracts, each of which contain an embedded derivative that indexes the price of power to the LME price of aluminum plus the Midwest premium. The embedded derivatives in these five power contracts are primarily valued using observable market prices; however, due to the length of the contracts, the valuation models also require management to estimate the long-term price of aluminum based upon an extrapolation of the 10-year LME forward curve and/or 5-year Also, Alcoa has a power contract separate from above that contains an LME-linked embedded derivative. 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 corresponding decrease to the derivative asset. This embedded derivative did not qualify for hedge accounting treatment. Unrealized gains and losses from the embedded derivative were included in Other (income) expenses, 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 were made under the contract. At the time this derivative asset was recognized, an equivalent amount was recognized as a deferred credit in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. This deferred credit is recognized in Other (income) expenses, net on the accompanying Statement of Consolidated Operations as power is received over the life of the contract. Alcoa had a similar power contract and related embedded derivative associated with another smelter and rolling mill combined; however, the contract and related derivative instrument matured in July 2014. Additionally, Alcoa has a natural gas supply contract, which has an LME-linked ceiling. This embedded derivative 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. This embedded derivative did not qualify for hedge accounting treatment. Unrealized gains and losses from the embedded derivative were included in Other (income) expenses, 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 gas purchases were made under the contract. Furthermore, Alcoa has 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. 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 a higher cost of power and a corresponding increase in the derivative liability. This embedded derivative did not qualify for hedge accounting treatment. Unrealized gains and losses were included in Other (income) expenses, 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 were made under the contract. Finally, Alcoa has a derivative contract that will hedge the anticipated power requirements at one of its smelters once the existing power contract expires in 2016. Beyond the term where market information is available, management has developed a forward curve, for valuation purposes, based on independent consultant market research. Significant increases or decreases in the power market may result in a higher or lower fair value measurement. Lower prices in the power market would cause a decrease in the derivative asset. The derivative contract has been designated as a cash flow hedge of future purchases of electricity. Unrealized gains and losses on this contract were recorded in Other comprehensive income (loss) on the accompanying Consolidated Balance Sheet. Once the designated hedge period begins in 2016, realized gains and losses will be recorded in Cost of goods sold as electricity purchases are made under the power contract. The following table presents quantitative information related to the significant unobservable inputs described above for Level 3 derivative contracts: Fair value at June 30, 2015* Unobservable input Range ($ in full amounts) Assets: Embedded aluminum derivatives $ 557 Price of aluminum beyond forward curve Aluminum: $2,660 per metric ton in 2025 to $2,460 per metric ton in 2029 (two contracts) and $2,756 per metric ton in 2036 (one contract) Midwest premium: $0.0920 per pound in 2020 to $0.0920 per pound in 2029 (two contracts) and 2036 (one contract) Embedded aluminum derivative 119 Interrelationship of future aluminum prices, foreign currency exchange rates, and the U.S. consumer price index (CPI) Aluminum: $1,668 per metric ton in 2015 to $1,761 per metric ton in 2016 Foreign currency: A$1 = $0.77 in 2015 to $0.77 in 2016 CPI: 1982 base year of 100 and 234 in 2015 to 241 in 2016 Embedded aluminum derivative — Interrelationship of future aluminum and oil prices Aluminum: $1,668 per metric ton in 2015 to $1,910 per metric ton in 2018 Oil: $62 per barrel in 2015 to $72 per barrel in 2018 Liabilities: Embedded aluminum derivative 294 Price of aluminum beyond forward curve Aluminum: $2,260 per metric ton in 2025 to $2,353 per metric ton in 2027 Embedded aluminum derivative — Interrelationship of LME price to overall energy price Aluminum: $1,802 per metric ton in 2015 to $1,935 per metric ton in 2019 Embedded credit derivative 19 Credit spread between Alcoa and counterparty 1.65% to 1.95% (1.80% median) Energy contract 9 Price of electricity beyond forward curve Electricity: $43 per megawatt hour in 2018 to $130 per megawatt hour in 2036 * The fair value of embedded aluminum derivatives reflected as assets and liabilities in this table are both lower by $4 compared to the respective amounts reflected in the Level 3 table presented below. This is due to the fact that Alcoa has one derivative that is in an asset position for the current portion but is in a liability position for the noncurrent portion, and is reflected as such on the accompanying Consolidated Balance Sheet. However, this derivative is reflected as a net liability in the above table for purposes of presenting the assumptions utilized to measure the fair value of the derivative instrument in their entirety. The fair values of Level 3 derivative instruments recorded as assets and liabilities in the accompanying Consolidated Balance Sheet were as follows: June 30, 2015 December 31, Asset Derivatives Derivatives designated as hedging instruments: Prepaid expenses and other current assets: Embedded aluminum derivatives $ 49 $ 24 Other noncurrent assets: Embedded aluminum derivative 512 73 Energy contract — 2 Total derivatives designated as hedging instruments $ 561 $ 99 Derivatives not designated as hedging instruments*: Prepaid expenses and other current assets: Embedded aluminum derivatives $ 95 $ 98 Other noncurrent assets: Embedded aluminum derivatives 24 71 Total derivatives not designated as hedging instruments $ 119 $ 169 Total Asset Derivatives $ 680 $ 268 Liability Derivatives Derivatives designated as hedging instruments: Other current liabilities: Embedded aluminum derivative $ 17 $ 24 Other noncurrent liabilities and deferred credits: Embedded aluminum derivatives 281 352 Energy contract 9 — Total derivatives designated as hedging instruments $ 307 $ 376 Derivatives not designated as hedging instruments*: Other current liabilities: Embedded credit derivative $ 3 $ 2 Other noncurrent liabilities and deferred credits: Embedded credit derivative 16 16 Total derivatives not designated as hedging instruments $ 19 $ 18 Total Liability Derivatives $ 326 $ 394 * See the “Other” section within Note N for additional information on Alcoa’s purpose for entering into derivatives not designated as hedging instruments and its overall risk management strategies.

Derivatives Designated As Hedging Instruments – Cash Flow Hedges For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of unrealized gains or losses on the derivative is reported as a component of other comprehensive income (OCI). Realized gains or losses on the derivative are reclassified from OCI into earnings in the same period or periods during which the hedged transaction impacts earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized directly in earnings immediately. Alcoa has five Level 3 embedded aluminum derivatives and one Level 3 energy contract that have been designated as cash flow hedges as follows. Embedded aluminum derivatives. In the 2015 second quarter and six-month period and the 2014 second quarter and six-month period, Alcoa recognized an unrealized gain of $616 and $518 and an unrealized loss of $54 and $24, respectively, in Other comprehensive income (loss) related to these five derivative instruments. Additionally, Alcoa reclassified a realized loss of $12 and $24 and $6 and $11 from Accumulated other comprehensive loss to Sales in the 2015 second quarter and six-month period and the 2014 second quarter and six-month period, respectively. Assuming market rates remain constant with the rates at June 30, 2015, a realized gain of $21 is expected to be recognized in Sales over the next 12 months. In the 2015 second quarter and six-month period and the 2014 second quarter and six-month period, Alcoa also recognized a gain of less than $1 and $1 and $1 and $1, respectively, in Other (income) expenses, net related to the amount excluded from the assessment of hedge effectiveness. There was no ineffectiveness related to these five derivative instruments in the 2015 second quarter and six-month period and the 2014 second quarter and six-month period. Energy contract. Derivatives Not Designated As Hedging Instruments Alcoa has two Level 3 embedded aluminum derivatives and one Level 3 embedded credit derivative that do not qualify for hedge accounting treatment. As such, gains and losses related to the changes in fair value of these instruments are recorded directly in earnings. In the second quarter of 2015 and 2014, Alcoa recognized a loss of $5 and a gain of $6, respectively, in Other (income) expenses, net, of which a loss of $2 and less than $1, respectively, related to the two embedded aluminum derivatives and a loss of $3 and a gain of $6, respectively, related to the embedded credit derivative. In the six-month period of 2015 and 2014, Alcoa recognized a loss of $2 and a gain of $7, respectively, in Other (income) expenses, net, of which a loss of $1 and less than $1, respectively, related to the two embedded aluminum derivatives and a loss of $1 and gain of $7, respectively, related to the embedded credit derivative. 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 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: June 30, 2015 December 31, 2014 Carrying Fair value Carrying Fair value Cash and cash equivalents $ 1,311 $ 1,311 $ 1,877 $ 1,877 Restricted cash 29 29 20 20 Noncurrent receivables 17 17 17 17 Available-for-sale securities 157 157 153 153 Short-term borrowings 50 50 54 54 Commercial paper — — — — Long-term debt due within one year 26 26 29 29 Long-term debt, less amount due within one year 8,713 9,215 8,769 9,445 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.

Schedule of Quantitative Information for Level 3 Derivative Contracts | The following table presents quantitative information related to the significant unobservable inputs described above for Level 3 derivative contracts: Fair value at June 30, 2015* Unobservable input Range ($ in full amounts) Assets: Embedded aluminum derivatives $ 557 Price of aluminum beyond forward curve Aluminum: $2,660 per metric ton in 2025 to $2,460 per metric ton in 2029 (two contracts) and $2,756 per metric ton in 2036 (one contract) Midwest premium: $0.0920 per pound in 2020 to $0.0920 per pound in 2029 (two contracts) and 2036 (one contract) Embedded aluminum derivative 119 Interrelationship of future aluminum prices, foreign currency exchange rates, and the U.S. consumer price index (CPI) Aluminum: $1,668 per metric ton in 2015 to $1,761 per metric ton in 2016 Foreign currency: A$1 = $0.77 in 2015 to $0.77 in 2016 CPI: 1982 base year of 100 and 234 in 2015 to 241 in 2016 Embedded aluminum derivative — Interrelationship of future aluminum and oil prices Aluminum: $1,668 per metric ton in 2015 to $1,910 per metric ton in 2018 Oil: $62 per barrel in 2015 to $72 per barrel in 2018 Liabilities: Embedded aluminum derivative 294 Price of aluminum beyond forward curve Aluminum: $2,260 per metric ton in 2025 to $2,353 per metric ton in 2027 Embedded aluminum derivative — Interrelationship of LME price to overall energy price Aluminum: $1,802 per metric ton in 2015 to $1,935 per metric ton in 2019 Embedded credit derivative 19 Credit spread between Alcoa and counterparty 1.65% to 1.95% (1.80% median) Energy contract 9 Price of electricity beyond forward curve Electricity: $43 per megawatt hour in 2018 to $130 per megawatt hour in 2036 * The fair value of embedded aluminum derivatives reflected as assets and liabilities in this table are both lower by $4 compared to the respective amounts reflected in the Level 3 table presented below. This is due to the fact that Alcoa has one derivative that is in an asset position for the current portion but is in a liability position for the noncurrent portion, and is reflected as such on the accompanying Consolidated Balance Sheet. However, this derivative is reflected as a net liability in the above table for purposes of presenting the assumptions utilized to measure the fair value of the derivative instrument in their entirety. |
