results of operations, financial position, and cash flows. The results reported in these Consolidated Financial Statements are not necessarily indicative of the results that may be expected for the entire year. The 2015 year-end balance sheet data
was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (GAAP). This Form 10-Q report should be read in conjunction with Alcoa&#146;s
Annual Report on Form 10-K for the year ended December 31, 2015, which includes all disclosures required by GAAP. Certain amounts in previously issued financial statements were reclassified to conform to the current period presentation (see Note B).

2016, Alcoa adopted changes issued by the Financial Accounting Standards Board (FASB) 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,
previously, were required to be presented separately in an entity&#146;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 is no longer required. Notwithstanding this change, an entity is still 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. The
adoption of these changes had no impact on the Consolidated Financial Statements. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On January 1, 2016, Alcoa adopted changes issued by the
FASB to the analysis an entity must perform to determine whether it should consolidate certain types of legal entities.&nbsp;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.&nbsp;The adoption of these changes had no impact on the Consolidated Financial Statements. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On January 1, 2016, Alcoa adopted changes issued by the FASB to the presentation of debt issuance costs. Previously, such costs were required
to be presented as a noncurrent asset in an entity&#146;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&#146;s balance sheet as
a direct deduction from the carrying value of the related debt liability. The amortization of debt issuance costs remains unchanged. The FASB issued an update to these changes based on an announcement of the staff of the U.S. Securities and Exchange
Commission. This update provides an exception to the FASB changes allowing debt issuance costs related to line-of-credit arrangements to continue to be presented as an asset regardless of whether there are any outstanding borrowings under such
arrangement. This additional change also was adopted by Alcoa on January 1, 2016. This adoption is required on a retrospective basis; therefore, the December 31, 2015 Consolidated Balance Sheet has been updated to conform to the March 31, 2016
presentation. As a result, $51 of debt issuance costs (previously reported in Other noncurrent assets) were reclassified to the Long-term debt, less amount due within one year line item on the December 31, 2015 Consolidated Balance Sheet. </P>

changes to employee share-based payment accounting.&nbsp;Currently, an entity must determine for each share-based payment award whether the difference between the deduction for tax purposes and the compensation cost recognized for financial
reporting purposes results in either an excess tax benefit or a tax deficiency.&nbsp;Excess tax benefits are recognized in additional paid-in capital; tax deficiencies are recognized either as an offset to accumulated excess tax benefits, if any, or

in the income statement. Excess tax benefits are not recognized until the deduction reduces taxes payable. The changes require all excess tax benefits and tax deficiencies related to share-based
payment awards to be recognized as income tax expense or benefit in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity also should recognize
excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Additionally, the presentation of excess tax benefits related to share-based payment awards in the statement of cash flows is changed. Currently,
excess tax benefits must be separated from other income tax cash flows and classified as a financing activity. The changes require excess tax benefits to be classified along with other income tax cash flows as an operating activity. Also, the
changes require cash paid by an employer when directly withholding shares for tax-withholding purposes to be classified as a financing activity. Currently, there is no specific guidance on the classification in the statement of cash flows of cash
paid by an employer to the tax authorities when directly withholding shares for tax-withholding purposes. Additionally, for a share-based award to qualify for equity classification it cannot partially settle in cash in excess of the employer&#146;s
minimum statutory withholding requirements. The changes permit equity classification of share-based awards for withholdings up to the maximum statutory tax rates in applicable jurisdictions. These changes become effective for Alcoa on January 1,
2017. Management is currently evaluating the potential impact of these changes on the Consolidated Financial Statements. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In March 2016,
the FASB issued changes eliminating the requirement for an investor to adjust an equity method investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all
previous periods that the investment had been held as a result of an increase in the level of ownership interest or degree of influence.&nbsp;Additionally, an entity that has an available-for-sale equity security that becomes qualified for the
equity method of accounting must recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method.&nbsp;These changes become effective
for Alcoa on January 1, 2017.&nbsp;Management is currently evaluating the potential impact of these changes on the Consolidated Financial Statements. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In March 2016, the FASB issued changes to derivative instruments designated as hedging instruments.&nbsp;These changes clarify that a change
in the counterparty to a derivative instrument that has been designated as a hedging instrument does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met.
These changes become effective for Alcoa on January 1, 2017.&nbsp;Management does not expect these changes to have a material impact on the Consolidated Financial Statements. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In February 2016, the FASB issued changes to the accounting and presentation of leases.&nbsp;These changes require lessees to recognize a
right of use asset and lease liability on the balance sheet for all leases with terms longer than 12 months.&nbsp;For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset
not to recognize a right of use asset and lease liability.&nbsp;Additionally, when measuring assets and liabilities arising from a lease, optional payments should be included only if the lessee is reasonably certain to exercise an option to extend
the lease, exercise a purchase option, or not exercise an option to terminate the lease.&nbsp;These changes become effective for Alcoa on January 1, 2019.&nbsp;Management is currently evaluating the potential impact of these changes on the
Consolidated Financial Statements.</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In January 2016, the FASB issued changes to equity investments.&nbsp;These changes require equity
investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income.&nbsp;However, an entity may choose
to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the
same issuer.&nbsp;Additionally, the impairment assessment of equity investments without readily determinable fair values has been simplified by requiring a qualitative assessment to identify impairment. These changes become effective for Alcoa on
January 1, 2018.&nbsp;Management is currently evaluating the potential impact of these changes on the Consolidated Financial Statements. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In July 2015, the FASB issued changes to the subsequent measurement of inventory.&nbsp;Currently, an entity is required to measure its
inventory at the lower of cost or market, whereby market can be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin.&nbsp;The changes require that inventory be measured at the lower of cost and
net realizable value, thereby eliminating the use of the other two market methodologies.&nbsp;Net realizable value is defined as the estimated selling prices in the ordinary course of business less reasonably predictable costs of completion,
disposal, and transportation.&nbsp;These changes do not apply to inventories measured using LIFO (last-in, first-out) or the retail inventory method.&nbsp;Currently, Alcoa applies the net realizable value market option to measure non-LIFO
inventories at the lower of cost or market.&nbsp;These changes become effective for Alcoa on January 1, 2017.&nbsp;Management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In May 2014, the FASB issued changes to the recognition of revenue from contracts with
customers.&nbsp;These changes created a comprehensive framework for all entities in all industries to apply in the determination of when to recognize revenue, and, therefore, supersede virtually all existing revenue recognition requirements and
guidance.&nbsp;This framework is expected to result in less complex guidance in application while providing a consistent and comparable methodology for revenue recognition.&nbsp;The core principle of the guidance is that an entity should recognize
revenue to depict the transfer of promised goods or services.&nbsp;To achieve this principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract(s),
(iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract(s), and (v) recognize revenue when, or as, the entity satisfies a performance obligation.&nbsp;In August 2015, the FASB
deferred the effective date by one year, making these changes effective for Alcoa on January 1, 2018.&nbsp;In March 2016, the FASB issued amendments to clarify the implementation guidance on principal versus agent considerations.&nbsp;Management is
currently evaluating the potential impact of these changes on the Consolidated Financial Statements. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In August 2014, the FASB issued
changes to the disclosure of uncertainties about an entity&#146;s ability to continue as a going concern. Under GAAP, continuation of a reporting entity as a going concern is presumed as the basis for preparing financial statements unless and until
the entity&#146;s liquidation becomes imminent. Even if an entity&#146;s liquidation is not imminent, there may be conditions or events that raise substantial doubt about the entity&#146;s ability to continue as a going concern. Because there is no
guidance in GAAP about management&#146;s responsibility to evaluate whether there is substantial doubt about an entity&#146;s ability to continue as a going concern or to provide related note disclosures, there is diversity in practice whether,
when, and how an entity discloses the relevant conditions and events in its financial statements. As a result, these changes require an entity&#146;s management to evaluate whether there are conditions or events, considered in the aggregate, that
raise substantial doubt about the entity&#146;s ability to continue as a going concern within one year after the date that financial statements are issued. Substantial doubt is defined as an indication that it is probable that an entity will be
unable to meet its obligations as they become due within one year after the date that financial statements are issued. If management has concluded that substantial doubt exists, then the following disclosures should be made in the financial
statements: (i)&nbsp;principal conditions or events that raised the substantial doubt, (ii)&nbsp;management&#146;s evaluation of the significance of those conditions or events in relation to the entity&#146;s ability to meet its obligations,
(iii)&nbsp;management&#146;s plans that alleviated the initial substantial doubt or, if substantial doubt was not alleviated, management&#146;s plans that are intended to at least mitigate the conditions or events that raise substantial doubt, and
(iv)&nbsp;if the latter in (iii)&nbsp;is disclosed, an explicit statement that there is substantial doubt about the entity&#146;s ability to continue as a going concern. These changes become effective for Alcoa for the 2016 annual financial
statements. Management has determined that the adoption of these changes will not have an impact on the Consolidated Financial Statements. Subsequent to adoption, this guidance will need to be applied by management at the end of each annual period
and interim period therein to determine what, if any, impact there will be on the Consolidated Financial Statements in a given reporting period. </P>

retirement obligations, as this liability was included in Alcoa&#146;s separate reserves for asset retirement obligations. In 2015, Other for layoff costs also included a reclassification of $35 in pension and/or other postretirement benefit costs,
as these obligations were included in Alcoa&#146;s separate liabilities for pension and other postretirement obligations. Additionally, in 2015, Other for exit costs also included a reclassification of $76 and $86 in asset retirement obligations and
environmental obligations, respectively, as these liabilities were included in Alcoa&#146;s separate reserves for asset retirement obligations and environmental remediation. </TD></TR></TABLE>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The remaining reserves are expected to be paid in cash during the remainder of 2016, with the exception of approximately $15 to $20, which is

 <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>E. Acquisitions and Divestitures</B> &#150; In March 2015, Alcoa completed the acquisition of an aerospace structural castings company,
TITAL, for $205 (&#128;189) in cash. Alcoa recognized goodwill of $117 for this transaction, none of which is deductible for income tax purposes. The purchase price allocation has been finalized. </P>
 <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In July 2015, Alcoa completed the acquisition of RTI International Metals, Inc. (RTI). RTI was 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 was to expand Alcoa&#146;s range of titanium offerings and add advanced technologies
and materials, primarily related to the aerospace end market. Alcoa purchased all outstanding shares of RTI common stock in a stock-for-stock transaction valued at $870 (based on the $9.96 per share July 23, 2015 closing price of Alcoa&#146;s common
stock). Each issued and outstanding share of RTI common stock prior to the completion of the transaction was converted into the right to receive 2.8315 shares of Alcoa common stock. In total, Alcoa issued 87,397,414 shares of its common stock to
consummate this transaction. The operating results and assets and liabilities of RTI were included within Alcoa&#146;s Engineered Products and Solutions segment since the date of acquisition. Based on the preliminary allocation of the purchase
price, goodwill of $251 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&#146;s best estimates, including a third-party
valuation of the assets acquired and other studies related to potential environmental and contingent liabilities. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In March 2016, Alcoa
reached an agreement for the sale of its Remmele Medical business for $102 in cash, subject to post-closing adjustments (this transaction closed on April&nbsp;29, 2016). This business, which was acquired by Alcoa in July 2015 in conjunction with the
RTI acquisition, generated sales of approximately $16 in the first quarter of 2016. The operating results and assets and liabilities of the business were included in the Engineered Products and Solutions segment.</P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Also in March 2016, Alcoa&#146;s majority-owned subsidiary, Alcoa of Australia Limited (AofA), which is part of Alcoa World Alumina and
Chemicals (AWAC), reached an agreement to sell its 20% interest in DBP, the owner and operator of the Dampier to Bunbury Natural Gas Pipeline (DBNGP) for $154 (A$205) in cash. As part of the transaction, AofA will maintain its current access to
approximately 30% of the DBNGP transmission capacity for gas supply to its three alumina refineries in Western Australia.&nbsp;See Note&nbsp;G for additional information. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Additionally in March 2016, Alcoa sold certain company-owned life insurance contracts for $234 in cash.&nbsp;No gain or loss was recognized on
the sale of these contracts.&nbsp;These contracts were included in Other noncurrent assets on the accompanying Consolidated Balance Sheet at December&nbsp;31, 2015. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In the first quarter of 2015, 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.&nbsp;The divestiture and post-closing adjustments combined resulted in a net cash payment of $8 and a net loss of $149 ($142 after-tax and
noncontrolling interest), which was recorded in Restructuring and other charges (see Note D) on the accompanying Statement of Consolidated Operations.&nbsp;These four divestitures are no longer subject to post-closing adjustments. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In March 2015, Alcoa completed the sale of a rolling mill located in Belaya Kalitva, Russia to a wholly-owned subsidiary of Stupino Titanium

Delaware Chancery Court for a declaratory judgment and injunctive relief to resolve a dispute between Alcoa and Glencore Ltd. (&#147;Glencore&#148;) with respect to claimed obligations under a 1995 asset purchase agreement between Alcoa and
Glencore.&nbsp;The dispute arose from Glencore&#146;s demand that Alcoa indemnify it for liabilities it may have to pay to Lockheed Martin (&#147;Lockheed&#148;) related to the St. Croix alumina refinery.&nbsp;Lockheed had earlier filed suit against
Glencore in federal court in New York seeking indemnity for liabilities it had incurred and would incur to the U.S. Virgin Islands to remediate certain properties at the refinery property and claimed that Glencore was required by an earlier, 1989
purchase agreement to indemnify it.&nbsp;Glencore had demanded that Alcoa indemnify and defend it in the Lockheed case and threatened to claim against Alcoa in the New York action despite exclusive jurisdiction for resolution of disputes under the
1995 purchase agreement being in Delaware.&nbsp;After Glencore conceded that it was not seeking to add Alcoa to the New York action, AWA and SCA dismissed their complaint in the Chancery Court case and on August 6, 2015 filed a complaint for
declaratory judgment in Delaware Superior Court.&nbsp;AWA and SCA filed a motion for judgment on the pleadings on September 16, 2015. Glencore answered AWA&#146;s and SCA&#146;s complaint and asserted counterclaims on August 27, 2015, and on October
2, 2015 filed its own motion for judgment on the pleadings.&nbsp;Argument on the parties&#146; motions was held by the court on December 7, 2015, and by order dated February 8, 2016, the court granted Alcoa&#146;s motion and denied Glencore&#146;s
motion, resulting in Alcoa not being liable to indemnify Glencore for the Lockheed action. The decision also leaves for pretrial discovery and possible summary judgment or trial Glencore&#146;s claims for costs and fees it incurred in defending and
settling an earlier Superfund action brought against Glencore by the Government of the Virgin Islands. On February 17, 2016, Glencore filed notice of its application for interlocutory appeal of the February&nbsp;8 ruling. AWA and SCA filed an
opposition to that application on February 29, 2016. On March 10, 2016, the court denied Glencore&#146;s motion for interlocutory appeal and on the same day entered judgment on claims other than Glencore&#146;s claims for costs and fees it incurred
in defending and settling the earlier Superfund action brought against Glencore by the Government of the Virgin Islands. On March 29, 2016, Glencore filed a withdrawal of its notice of interlocutory appeal and also noted its intent to appeal the
court&#146;s March 10, 2016 judgment. At this time, the Company is unable to reasonably predict an outcome for this matter. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">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 (&#147;204/1999&#148;). 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 &#147;state aid.&#148; In 2010, the

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).&nbsp;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 (&#128;85), including interest.&nbsp;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 (&#147;44/2012&#148;) came into effect, changing the method to calculate the drawback. On February 21, 2013, Alcoa received a revised request letter from CCSE demanding Alcoa&#146;s subsidiary, Alcoa Trasformazioni S.r.l., make a payment
in the amount of $97 (&#128;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 (&#128;76). Alcoa rejected
that demand and 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 that date, the Administrative Court listened to Alcoa&#146;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&#146;s September 2, 2014
decision; however, a date for the hearing has not been scheduled. Management recorded a partial reserve for this matter of $37 (&#128;34) during the quarter ended December 31, 2015 (see Note N in the Company&#146;s Annual Report on Form 10-K for the

entity owned by the Italian Government. At the time of the acquisition, Alumix indemnified Alcoa for pre-existing environmental contamination at the sites. In 2004, the Italian Ministry of Environment and Protection of Land and Sea (MOE) issued
orders to Trasformazioni and Alumix for the development of a clean-up plan related to soil contamination in excess of allowable limits under legislative decree and to institute emergency actions and pay natural resource damages. Trasformazioni
appealed the orders and filed suit against Alumix, among others, seeking indemnification for these liabilities under the provisions of the acquisition agreement. In 2009, Ligestra S.r.l. (&#147;Ligestra&#148;), Alumix&#146;s successor, and
Trasformazioni agreed to a stay of the court proceedings while investigations were conducted and negotiations advanced towards a possible settlement. </P>

formally presented to the MOE in mid-2010.&nbsp;The agreement was contingent upon final acceptance of the remediation project by the MOE.&nbsp;As a result of entering into this agreement, Alcoa increased the reserve by $12 in 2009 for
Fusina.&nbsp;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.&nbsp;In October 2013, the MOE approved the project submitted by Alcoa, resulting in no adjustment to the reserve. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">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.
The agreement includes both a soil and groundwater remediation project estimated to cost $33 (&#128;24) and requires payments of $25 (&#128;18) to the MOE for emergency action and natural resource damages. The remediation projects are slated to
begin as soon as Alcoa receives final approval from the Ministry of Infrastructure. Based on the final agreement with Ligestra, Alcoa&#146;s share of all costs and payments is $17 (&#128;12), of which $9 (&#128;6) related to the damages will be paid

the one for Fusina.&nbsp;A proposed soil remediation project for Portovesme was formally presented to the MOE in June 2012.&nbsp;Neither the agreement with Ligestra nor the proposal to the MOE resulted in a change to the reserve for
Portovesme.&nbsp;In November 2013, the MOE rejected the proposed soil remediation project and requested a revised project be submitted.&nbsp;In May 2014, Trasformazioni and Ligestra submitted a revised soil remediation project that addressed certain

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.&nbsp;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 S&atilde;o Lu&iacute;s 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.&nbsp;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.&nbsp;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.&nbsp;Separately
from AWAB&#146;s administrative appeal, in June 2015, new tax law was enacted repealing the provisions in the tax code that were the basis for the RFB assessing a 50% penalty in this matter. As such, the estimated range of reasonably possible loss
is $0 to $29 (R$103), whereby the maximum end of the range represents the portion of the disallowed credits applicable to the export sales and excludes the 50% penalty. Additionally, the estimated range of disallowed credits related to AWAB&#146;s
fixed assets is $0 to $32 (R$117), which would increase the net carrying value of AWAB&#146;s fixed assets if ultimately disallowed. It is management&#146;s opinion that the allegations have no basis; however, at this time, management is unable to
reasonably predict an outcome for this matter. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Between 2000 and 2002, Alcoa Alum&iacute;nio (Alum&iacute;nio) sold approximately 2,000
metric tons of metal per month from its Po&ccedil;os de Caldas facility, located in the State of Minas Gerais (the &#147;State&#148;), to Alfio, a customer also located in the State.&nbsp;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, Alum&iacute;nio received an assessment from State auditors on the theory that Alum&iacute;nio should
be jointly and severally liable with Alfio for the unpaid VAT. In June 2003, the administrative tribunal found Alum&iacute;nio liable, and Alum&iacute;nio filed a judicial case in the State in February 2004 contesting the finding.&nbsp;In May 2005,
the Court of First Instance found Alum&iacute;nio solely liable, and a panel of a State appeals court confirmed this finding in April 2006.&nbsp;Alum&iacute;nio filed a special appeal to the Superior Tribunal of Justice (STJ) in Brasilia (the
federal capital of Brazil) later in 2006.&nbsp;In 2011, the STJ (through one of its judges) reversed the judgment of the lower courts, finding that Alum&iacute;nio should neither be solely nor jointly and severally liable with Alfio for the VAT,
which ruling was then appealed by the State.&nbsp;In August 2012, the STJ agreed to have the case reheard before a five-judge panel.&nbsp;A decision from this panel is pending, but additional appeals are likely.&nbsp;At March 31, 2016, the
assessment totaled $38 (R$137), including penalties and interest.&nbsp;While the Company believes it has meritorious defenses, the Company is unable to reasonably predict an outcome. </P>

partners (see below). Both the equity contributions and the guarantees of the project financing are based on the joint venture&#146;s partners&#146; ownership interests. Originally, it was
estimated that Alcoa&#146;s total equity investment in the joint venture would be approximately $1,100, of which Alcoa has contributed $982, including $1 in the 2016 first quarter. Based on changes to both the project&#146;s capital investment and
equity and debt structure from the initial plans, the estimated $1,100 equity contribution may be reduced. As of March 31, 2016 and December 31, 2015, the carrying value of Alcoa&#146;s investment in this project was $906 and $928, respectively.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The smelting and rolling mill companies have project financing totaling $4,311 (reflects principal repayments made through March 31,
2016), of which $1,082 represents Alcoa&#146;s share (the equivalent of Alcoa&#146;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&#146;aden issued similar guarantees for its 74.9%
interest). Alcoa&#146;s guarantees for the smelting and rolling mill companies cover total debt service requirements of $142 in principal and up to a maximum of approximately $40 in interest per year (based on projected interest rates). At March 31,
2016 and December&nbsp;31, 2015, the combined fair value of the guarantees was $7 in both periods, which was included in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. </P>

similar guarantees for its 74.9% interest). Alcoa&#146;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

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In 2004, AofA 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 AofA&#146;s
refineries in Western Australia. AofA 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&#146;s
capacity is planned at this time. In late 2011, the consortium initiated a three-year equity call plan to improve its capitalization structure. The plan required AofA 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 AofA to contribute $30 (A$36) through mid 2016, of which $20
(A$27) was made through March 31, 2016, including $3 (A$5) in the 2016 first quarter. In addition to its equity ownership, AofA has an agreement to purchase gas transmission services from the DBNGP. At March 31, 2016, Alcoa has an asset of $284
(A$369) representing prepayments made under the agreement for future gas transmission services. AofA&#146;s maximum exposure to loss on the investment and the related contract is approximately $400 (A$520) as of March 31, 2016. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In April 2016, AofA completed the sale of its 20% interest in DBP, the owner and operator of the DBNGP for $154 (A$205). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In April 2015, AofA secured a new 12-year gas supply agreement to power its three alumina refineries in Western Australia beginning in July
2020.&nbsp;This agreement was conditional on the completion of a third-party acquisition of the related energy assets from the then-current owner, which occurred in June 2015.&nbsp;The terms of AofA&#146;s gas supply agreement require a prepayment
of $500 to be made in two installments.&nbsp;The first installment of $300 was made in the second quarter of 2015 and the second installment of $200 was paid in April 2016. At March 31, 2016 and December 31, 2015, an asset of $304 (A$395) and $288

 <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>L. Receivables</B> &#150; Alcoa has an arrangement with three financial institutions to sell certain customer receivables without recourse
on a revolving basis. The sale of such receivables is completed through the use of a bankruptcy remote special purpose entity, which is a consolidated subsidiary of Alcoa. This arrangement provides for minimum funding of $200 up to a maximum of $500
for receivables sold. On March 30, 2012, Alcoa initially sold $304 of customer receivables in exchange for $50 in cash and $254 of deferred purchase price under this arrangement. Alcoa has received additional net cash funding of $300 for receivables
sold ($1,358 in draws and $1,058 in repayments) since the program&#146;s inception. Draws and repayments in the 2016 first quarter were $100 and $0, respectively. </P>
 <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As of March 31, 2016 and December 31, 2015, the deferred purchase price receivable was $210 and $249, respectively, which
was included in Other receivables on the accompanying Consolidated Balance Sheet.&nbsp;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.&nbsp;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.&nbsp;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. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The gross amount of receivables sold and total cash collected under this program since its inception was $26,055 and $25,495,
respectively.&nbsp;Alcoa services the customer receivables for the financial institutions at market rates; therefore, no servicing asset or liability was recorded. </P>

2015, management elected to change the manner in which the interest cost component of net periodic benefit cost is determined in 2016 and beyond. Previously, the interest cost component was determined by multiplying the single equivalent rate and
the aggregate discounted cash flows of the plans&#146; projected benefit obligations. Under the new methodology, the interest cost component is determined by aggregating the product of the discounted cash flows of the plans&#146; projected benefit
obligations for each year and an individual spot rate (referred to as the &#147;spot rate&#148; approach). This change resulted in a lower interest cost component of net periodic benefit cost for the pension plans and other postretirement benefit
plans of $24 and $4, respectively, in the first quarter of 2016. </P>

aluminum, energy, interest rate, and foreign exchange contracts are held for purposes other than trading.&nbsp;They are used primarily to mitigate uncertainty and volatility, and to cover underlying exposures.&nbsp;Alcoa is not involved in trading

Financial Statements for all periods. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">For the aluminum contracts classified as Level 1, the total fair value of derivatives recorded as
assets and liabilities was $4 and $35 and $8 and $58 at March 31, 2016 and December 31, 2015, respectively.&nbsp;These contracts were entered into to either hedge forecasted sales or purchases of aluminum in order to manage the associated aluminum
price risk.&nbsp;Certain of these contracts are designated as hedging instruments, either fair value or cash flow, and the remaining are not designated as such.&nbsp;Combined, Alcoa recognized a net gain of $2 and $26 in the first quarter of 2016
and 2015, respectively, in Sales on the accompanying Statement of Consolidated Operations related to these aluminum contracts. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">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.&nbsp;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.&nbsp;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. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The following section describes the valuation methodologies used by Alcoa to measure its Level 3 derivative instruments at fair
value.&nbsp;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.&nbsp;Alcoa uses a discounted cash flow model to
fair value all Level 3 derivative instruments.&nbsp;Where appropriate, the description below includes the key inputs to those models and any significant assumptions.&nbsp;These valuation models are reviewed and tested at least on an annual basis.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">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).&nbsp;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.&nbsp;Additionally, for periods beyond the term of quoted market prices for energy, management has developed a forward curve based on independent consultant market research.&nbsp;Where appropriate,
valuations are adjusted for various factors such as liquidity, bid/offer spreads, and credit considerations.&nbsp;Such adjustments are generally based on available </P>

market evidence (Level 2). In the absence of such evidence, management&#146;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). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Alcoa has embedded derivatives in two power contracts that index the price of power to the LME price of aluminum.&nbsp;Additionally, Alcoa has
embedded derivatives in 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.&nbsp;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 Midwest premium curve.&nbsp;Significant increases or decreases in the actual LME price beyond 10 years and/or the Midwest premium beyond 5 years would result in a higher or lower fair value measurement.&nbsp;An increase in actual LME
price and/or the Midwest premium over the inputs used in the valuation models will result in a higher cost of power and a corresponding decrease to the derivative asset or increase to the derivative liability.&nbsp;The embedded derivatives have been
designated as cash flow hedges of forward sales of aluminum.&nbsp;Unrealized gains and losses were included in Other comprehensive loss on the accompanying Consolidated Balance Sheet while realized gains and losses were included in Sales on the
accompanying Statement of Consolidated Operations. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Also, Alcoa has a power contract separate from above that contains an LME-linked
embedded derivative.&nbsp;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.&nbsp;Significant increases or decreases
in the LME price would result in a higher or lower fair value measurement.&nbsp;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.&nbsp;This embedded derivative did not qualify for hedge accounting treatment.&nbsp;Unrealized gains and losses from the embedded derivative were included in Other expenses (income), net on the accompanying Statement of Consolidated Operations
while realized gains and losses were included in Cost of goods sold on the accompanying Statement of Consolidated Operations as electricity purchases were made under the contract.&nbsp;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.&nbsp;This deferred credit is recognized in Other expenses (income), net on the accompanying Statement of
Consolidated Operations as power is received over the life of the contract.</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Additionally, Alcoa has a natural gas supply contract, which
has an LME-linked ceiling.&nbsp;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.&nbsp;Any change in the interrelationship would result in a higher or lower fair value measurement.&nbsp;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.&nbsp;An increase in oil prices with no similar increase in the LME price would limit the increase of the price paid for natural gas.&nbsp;This embedded derivative did not qualify for hedge accounting treatment.&nbsp;Unrealized
gains and losses from the embedded derivative were included in Other expenses (income), net on the accompanying Statement of Consolidated Operations while realized gains and losses were included in Cost of goods sold on the accompanying Statement of
Consolidated Operations as gas purchases were made under the contract. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">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.&nbsp;Management uses market prices, historical relationships, and forecast services to determine fair
value.&nbsp;Significant increases or decreases in any of these inputs would result in a lower or higher fair value measurement.&nbsp;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.&nbsp;This embedded derivative did not qualify for hedge accounting treatment.&nbsp;Unrealized gains and losses were included in Other expenses (income), net on the accompanying Statement of Consolidated
Operations while realized gains and losses were included in Cost of goods sold on the accompanying Statement of Consolidated Operations as electricity purchases were made under the contract. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">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 September 2016.&nbsp;Beyond the term where market information is available, management has developed a forward curve, for valuation purposes, based on independent consultant market research.&nbsp;Significant increases or
decreases in the power market may result in a higher or lower fair value measurement.&nbsp;Lower prices in the power market would cause a decrease in the derivative asset.&nbsp;The derivative contract has been designated as a cash flow hedge of

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On September 28, 2015, Alcoa announced that its Board of Directors approved a plan to separate into two independent, publicly-traded
companies: An Upstream Company, the new Alcoa, that will primarily comprise the Alumina and Primary Metals segments; and a Value-Add Company, Arconic, that will principally include the Global Rolled Products, Engineered Products and Solutions, and
Transportation and Construction Solutions segments. The Company currently plans that upon separation, which is targeted in the second half of 2016, the new Alcoa will also become owner of the rolling mill at the Warrick, IN Operations and the stake
in the Ma&#146;aden Rolling Company in Saudi Arabia. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The transaction is subject to a number of conditions, including, but not limited to,
final approval by Alcoa&#146;s Board of Directors, receipt of a favorable opinion of legal counsel with respect to the tax-free nature of the transaction for U.S. federal income tax purposes, and the effectiveness of a Form 10 registration statement
to be filed with the U.S. Securities and Exchange Commission. Upon completion of the separation, Alcoa shareholders will own all of the outstanding shares of both companies. Alcoa may, at any time and for any reason until the proposed transaction is
complete, abandon the separation plan or modify or change its terms. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Results of Operations </B></P>

$195, or $0.14 per share, in the 2015 first quarter.&nbsp;The decrease in results of $179 was primarily the result of a lower average realized price for aluminum and alumina, partially offset by net productivity improvements and lower
restructuring-related charges. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Sales declined $872, or 15%, in the 2016 first quarter compared to the same period in 2015.&nbsp;The
decrease was largely attributable to a lower average realized price for alumina, a lower average realized price for aluminum in both the upstream and midstream operations, the absence of sales related to capacity that was closed, sold or curtailed
in the upstream and midstream operations (see Alumina, Primary Metals, and Global Rolled Products in Segment Information below), and net unfavorable foreign currency movements.&nbsp;These negative impacts were partially offset by the addition of
sales from two recently acquired businesses (see Engineered Products and Solutions in Segment Information below) and higher volumes in the upstream operations.</P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Cost of goods sold (COGS) as a percentage of Sales was 81.7% in the 2016 first quarter compared with 76.4% in the 2015 first quarter.&nbsp;The
percentage was negatively impacted by lower average realized prices for alumina and aluminum, partially offset by net productivity improvements across all segments. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Selling, general administrative, and other expenses (SG&amp;A) increased $28 in the 2016 first quarter compared to the corresponding period in
2015.&nbsp;The increase was primarily driven by new SG&amp;A related to inorganic growth in the Engineered Products and Solutions segment ($19) and expenses for professional and consulting services related to the planned separation (see above) of
Alcoa ($18).&nbsp;These increases were partially offset by a decrease in corporate overhead expenses.&nbsp;SG&amp;A as a percentage of Sales increased from 4.0% in the 2015 first quarter to 5.3% in the 2016 first quarter. </P>

quarter compared with the same period in 2015. The decrease was mainly caused by foreign currency movements due to a stronger U.S. dollar and the absence of DD&amp;A ($7) related to the curtailments or closures at Suriname, Po&ccedil;os de Caldas,
and Massena East in the Primary Metals segment and the sale of a Russian rolling mill in the Global Rolled Products segment, partially offset by new DD&amp;A of ($15) associated with two acquisitions that occurred from March 2015 through July 2015
in the Engineered Products and Solutions segment and new DD&amp;A associated with other growth projects. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Restructuring and other charges
in the 2016 first quarter were $93 ($61 after-tax and noncontrolling interest), which were comprised of the following components: $60 ($39 after-tax) related to the 2015 announced permanent closure of the Warrick smelter; $19 ($14 after-tax and
noncontrolling interest) for layoff costs, including the separation of approximately 560 employees (500 in the Engineered Products and Solutions segment, 30 in the Primary Metals segment, and 30 in the Global Rolled Products segment); $18 ($11
after-tax and noncontrolling interest) related to the curtailments of the Point Comfort refinery and Wenatchee smelter; and $4 ($3 after-tax and noncontrolling interest) for the reversal of a number of small layoff reserves related to prior periods
and other miscellaneous items. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In 2016, costs related to the closure and curtailment actions included $70 for accelerated depreciation as
the Warrick facility continued to operate through March 2016, $27 in other exit costs primarily for contract terminations, and $19 for the reversal of previously accrued severance costs that will not be incurred. Additionally in the first quarter of
2016, inventories were written down to their net realizable value, resulting in a charge of $3 ($2 after-tax), which was recorded in COGS. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Restructuring and other charges in the 2015 first quarter were $177 ($158 after-tax and noncontrolling interest), which were comprised of the
following components: $149 ($142 after-tax and noncontrolling interest) related to the March 2015 divestiture of a rolling mill in Russia (see Global Rolled Products in segment Information below) and post-closing adjustments associated with three
December 2014 divestitures; $16 ($11 after-tax) for the separation of approximately 680 employees (Primary Metals segment) and supplier contract-related costs associated with the decision to temporarily curtail the remaining capacity (74
kmt-per-year) at the S&atilde;o Lu&iacute;s smelter in Brazil (see Primary Metals in Segment Information below); $13 ($8 after-tax and noncontrolling interest) for layoff costs, including the separation of approximately 210 employees (80 in the
Engineered Products and Solutions segment, 40 in the Transportation and Construction Solutions segment, 30 in the Global Rolled Products segment, and 60 in Corporate); a net charge of $6 ($3 after-tax and noncontrolling interest) for other
miscellaneous items; and $7 ($6 after-tax) for the reversal of a number of small layoff reserves related to prior periods. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Alcoa does not

</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The rate for the 2016 first quarter differs from the U.S. federal statutory rate of 35% primarily due to book basis in excess of tax
basis of company-owned life insurance contracts that will be sold during 2016, separation expenses for which no tax benefit was recognized, and a $5 discrete income tax charge for valuation allowances of certain deferred tax assets in Australia.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The rate for the 2015 first quarter differs from the U.S. federal statutory rate of 35% primarily due to a loss on the sale of a rolling
mill in Russia (see Global Rolled Products in Segment Information below) for which no tax benefit was recognized, a $35 unfavorable impact related to the interim period treatment of losses in certain foreign jurisdictions for which no tax benefit
was recognized (impact reversed by the end of 2015), and a $33 net discrete income tax charge as described below, somewhat offset by foreign income taxed in lower rate jurisdictions. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In the first quarter of 2015, Alcoa World Alumina and Chemicals (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.&nbsp;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. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Net loss attributable to noncontrolling interests was $5 in the 2016 first quarter compared with Net income attributable to
noncontrolling interests of $60 in the 2015 first quarter. These amounts were virtually all related to Alumina Limited&#146;s 40% ownership interest in AWAC. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In the 2016 first quarter, AWAC generated a loss compared to income in the same period in 2015. The change in AWAC&#146;s results was mainly
driven by a lower average realized price for alumina.&nbsp;This negative impact was partially offset by net productivity improvements and net favorable foreign currency movements due to a stronger U.S. dollar, especially against the Australian
dollar and Brazilian real. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Segment Information </B></P>

by 2016.&nbsp;As part of this review, management decided to curtail all of the operating capacity at both the Suralco (1,330 kmt-per-year) and Point Comfort (2,010 kmt-per-year)
refineries.&nbsp;The curtailment of the capacity at Suralco was completed by the end of November 2015. Management is currently in discussions with the Suriname government to determine the best long-term solution for Suralco due to limited bauxite
reserves and the absence of a long-term energy alternative.&nbsp;The curtailment of the capacity at Point Comfort is expected to be completed by the end of June 2016 (1,553 kmt-per-year was completed by the end of March 31, 2016).&nbsp;Suralco and
Point Comfort have nameplate capacity of 2,207 kmt-per-year and 2,305 kmt-per-year, respectively, of which 877 kmt and 295 kmt, respectively, was curtailed prior to the review. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Third-party sales for the Alumina segment declined 39% in the 2016 first quarter compared to the same period in 2015.&nbsp;The decrease was
primarily due to a 28% decrease in average realized price and a 15% decline in volume.&nbsp;Unfavorable foreign currency movements also contributed to the decline in the 2016 first quarter.&nbsp;The change in average realized price was mostly driven
by a lower average alumina index/spot price. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Intersegment sales decreased 42% in the 2016 first quarter compared with the corresponding
period in 2015 due to lower demand from the Primary Metals segment, as a result of the closure, curtailment or divestiture of a number of smelters (see Primary Metals below), and a lower average realized price.</P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">ATOI for this segment decreased $213 in the 2016 first quarter compared to the same period in 2015.&nbsp;This decrease was principally driven
by the decline in Alumina Price Index and LME.&nbsp;These negative impacts were partially offset by net productivity improvements, net favorable foreign currency movements due to a stronger U.S. dollar, especially against the Australian dollar and
Brazilian real, and a higher percentage of shipments linked to alumina index/spot price. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In the second quarter of 2016 (comparison with
the 2015 second quarter), alumina production is expected to be down 16%, driven by the curtailments of the Suralco and Point Comfort refineries.&nbsp;Also, net productivity improvements are anticipated and third party bauxite sales are expected to

decided to curtail the remaining capacity at the Wenatchee smelter (143 kmt-per-year) and approved the permanent closure of the Warrick, IN smelter (269 kmt-per-year). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Also in March 2015, management decided to curtail the remaining capacity (74 kmt-per-year) at the S&atilde;o Lu&iacute;s smelter in Brazil;
this action was completed in April 2015. In 2013 and 2014 combined, Alcoa curtailed capacity of 194 kmt-per-year at the S&atilde;o Lu&iacute;s smelter under a prior management review. </P>

smelter (96 kmt-per-year) in Brazil effective immediately. The Po&ccedil;os de Caldas smelter had been temporarily idle since May 2014 due to challenging global market conditions for primary aluminum and higher operating costs, which made the
smelter uncompetitive. The decision to permanently close the Po&ccedil;os de Caldas smelter was based on the fact that these underlying conditions had not improved. </P>

quarter was the result of the absence of production at one smelter each in Brazil and the United States.&nbsp;Furthermore, the production at the Warrick smelter decreased in preparation for the closure of this smelter. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Third-party sales for the Primary Metals segment decreased 29% in the 2016 first quarter compared to the same period in 2015.&nbsp;The
decrease was mostly the result of a 26% decrease in average realized price, the absence of sales from two smelters that were curtailed in 2015, and unfavorable foreign currency movements, primarily due to a weaker Brazilian real.&nbsp;These negative
impacts were slightly offset by higher volume in the remaining smelter portfolio.&nbsp;The change in average realized price was driven by a 16% lower average LME price (on 15-day lag) and lower regional premiums, which dropped by an average of 61%
in the United States and Canada and 66% in Europe. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Intersegment sales declined 31% in the 2016 first quarter compared with the

segment decreased $173 in the 2016 first quarter compared to the same period in 2015.&nbsp;The decline was primarily driven by the previously mentioned lower average realized aluminum price. These negative price impacts were somewhat offset by net
productivity improvements and lower alumina costs. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In the second quarter of 2016 (comparison with the 2015 second quarter), aluminum

Alumina Limited.&nbsp;These items were mostly offset by $517 in additions to debt, virtually all of which was the result of borrowings under certain revolving credit facilities, a $26 change in short-term borrowings, and $24 in proceeds from

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I><U>Glencore Contractual Indemnity Claim.</U></I> As previously reported, on June 5, 2015, Alcoa World Alumina LLC (&#147;AWA&#148;) and St. Croix Alumina,
L.L.C. (&#147;SCA&#148;) filed a complaint in Delaware Chancery Court for a declaratory judgment and injunctive relief to resolve a dispute between Alcoa and Glencore Ltd. (&#147;Glencore&#148;) with respect to claimed obligations under a 1995 asset
purchase agreement between Alcoa and Glencore.&nbsp;The dispute arose from Glencore&#146;s demand that Alcoa indemnify it for liabilities it may have to pay to Lockheed Martin (&#147;Lockheed&#148;) related to the St. Croix alumina
refinery.&nbsp;Lockheed had earlier filed suit against Glencore in federal court in New York seeking indemnity for liabilities it had incurred and would incur to the U.S. Virgin Islands to remediate certain properties at the refinery property and
claimed that Glencore was required by an earlier, 1989 purchase agreement to indemnify it.&nbsp;Glencore had demanded that Alcoa indemnify and defend it in the Lockheed case and threatened to claim against Alcoa in the New York action despite
exclusive jurisdiction for resolution of disputes under the 1995 purchase agreement being in Delaware.&nbsp;After Glencore conceded that it was not seeking to add Alcoa to the New York action, AWA and SCA dismissed their complaint in the Chancery
Court case and on August 6, 2015 filed a complaint for declaratory judgment in Delaware Superior Court.&nbsp;AWA and SCA filed a motion for judgment on the pleadings on September 16, 2015.&nbsp;Glencore answered AWA&#146;s and SCA&#146;s complaint
and asserted counterclaims on August 27, 2015, and on October 2, 2015 filed its own motion for judgment on the pleadings.&nbsp;Argument on the parties&#146; motions was held by the court on December 7, 2015 and by order dated February 8, 2016, the
court granted Alcoa&#146;s motion and denied Glencore&#146;s motion, resulting in Alcoa not being liable to indemnify Glencore for the Lockheed action. The decision also leaves for pretrial discovery and possible summary judgment or trial
Glencore&#146;s claims for costs and fees it incurred in defending and settling an earlier Superfund action brought against Glencore by the Government of the Virgin Islands. On February 17, 2016, Glencore filed notice of its application for
interlocutory appeal of the February 8 ruling. AWA and SCA filed an opposition to that application on February 29, 2016. On March 10, 2016, the court denied Glencore&#146;s motion for interlocutory appeal and on the same day entered judgment on
claims other than Glencore&#146;s claims for costs and fees it incurred in defending and settling the earlier Superfund action brought against Glencore by the Government of the Virgin Islands. On March 29, 2016, Glencore filed a withdrawal of its
notice of interlocutory appeal and also noted its intent to appeal the court&#146;s March 10, 2016 judgment. At this time, the Company is unable to reasonably predict an outcome for this matter. </P>

2015, an Alcoa subsidiary, Al&#250;mina Espa&#241;ola S.A., received a request by the Court of Vivero, Spain to provide the names of the &#147;manager,&#148; as well as those of the &#147;environmental managers,&#148; of the San Cipri&#225;n alumina
refinery from 2009 to the present date.&nbsp;Upon reviewing the documents filed with the Court, Alcoa learned for the first time that the request is the result of a criminal proceeding that began in 2010 after the filing of a claim by two San
Cipri&#225;n neighbors alleging that the plant&#146;s activities had adverse effects on vegetation, crops and human health. In 2011 and 2012, some neighbors claimed individually in the criminal court for caustic spill damages to vehicles, and the
judge decided to administer all issues in the court proceeding (865/2011). Currently, that court proceeding is in its first phase (preliminary investigation phase) led by the judge. The purpose of that investigation is to determine whether there has
been a criminal offense for actions against natural resources and the environment. The Spanish public prosecutor is also involved in the case, having requested technical reports. To date, only &#147;Alcoa-Al&#250;mina Espa&#241;ola S.A.&#148; has
been identified as a potential defendant and no Alcoa representative has yet been required to appear before the judge. No other material step has been taken during this preliminary investigation phase. Monetary sanctions for an offense in the form
of a fine could range from 30 to 5,000 euros per day, for a maximum period of three years. Given that this proceeding is in its preliminary stage and the current uncertainty in the case, the Company is unable to reasonably predict an outcome or to
estimate a range of reasonably possible loss. </P>

contractors, and the communities in which Alcoa operates because it is fundamentally the right thing to do. Despite uncertainties and economic challenges, Alcoa remains committed to living its values and managing risks accordingly. In 2015,
44.4%&nbsp;of Alcoa&#146;s global locations reported no recordable injuries, and 79.1%&nbsp;reported zero lost workdays. In Alcoa&#146;s 2015 Employee Global Voices Survey, &#147;If I see a situation that is unsafe, I can stop work&#148; received
the highest overall rating (at 92% favorable) by employees participating in the survey. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Alcoa&#146;s health and safety systems are

weaknesses that develop in Alcoa&#146;s safety systems by identifying potential hazards and error-likely situations and responding to eliminate or control them. </P>

Mine Safety and Health Act of 1977 (the &#147;Mine Act&#148;). The MSHA inspects these facilities on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. Whenever the MSHA issues a
citation or order, it also generally proposes a civil penalty, or fine, related to the alleged violation. Citations or orders can be contested and appealed, and as part of that process, are often reduced in severity and amount, and are sometimes
dismissed. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Management believes the following mine safety disclosures meet the requirements of section 1503(a) of the Dodd-Frank Wall

under section 104 of the Mine Act, along with the contests of the proposed penalties for each of these. The remaining matter was a retaliation complaint filed by an employee, which was dismissed by an Administrative Law Judge on September&nbsp;28,
2015. The employee has appealed the dismissal to the Commission where the matter is currently pending. All of these matters concern citations, orders or proposed assessments issued by MSHA during 2016 (three), 2015 (seven) or 2014 (two). One of the
seven matters filed in 2015 was not previously reported because it was filed by the U.S. Secretary of Labor on December&nbsp;30, 2015, which was not received by Alcoa until 2016. </P>

 In conjunction with the annual measurement of the funded status of
 Alcoa&amp;#x2019;s pension and other postretirement benefit plans at
 December 31, 2015, management elected to change the manner in which
 the interest cost component of net periodic benefit cost is
 determined in 2016 and beyond. Previously, the interest cost
 component was determined by multiplying the single equivalent rate
 and the aggregate discounted cash flows of the plans&amp;#x2019;
 projected benefit obligations. Under the new methodology, the
 interest cost component is determined by aggregating the product of
 the discounted cash flows of the plans&amp;#x2019; projected benefit
 obligations for each year and an individual spot rate (referred to
 as the &amp;#x201C;spot rate&amp;#x201D; approach). This change resulted in a
 lower interest cost component of net periodic benefit cost for the
 pension plans and other postretirement benefit plans of $24 and $4,
 respectively, in the first quarter of 2016.&lt;/p&gt;

 On January 1, 2016, Alcoa adopted changes issued by the Financial
 Accounting Standards Board (FASB) 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, previously, were required to be presented
 separately in an entity&amp;#x2019;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 is no longer required. Notwithstanding
 this change, an entity is still 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. The
 adoption of these changes had no impact on the Consolidated
 Financial Statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 On January 1, 2016, Alcoa adopted changes issued by the FASB to the
 analysis an entity must perform to determine whether it should
 consolidate certain types of legal entities.&amp;#xA0;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.&amp;#xA0;The adoption of these changes
 had no impact on the Consolidated Financial Statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 On January 1, 2016, Alcoa adopted changes issued by the FASB to the
 presentation of debt issuance costs. Previously, such costs were
 required to be presented as a noncurrent asset in an entity&amp;#x2019;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&amp;#x2019;s balance sheet as a direct
 deduction from the carrying value of the related debt liability.
 The amortization of debt issuance costs remains unchanged. The FASB
 issued an update to these changes based on an announcement of the
 staff of the U.S. Securities and Exchange Commission. This update
 provides an exception to the FASB changes allowing debt issuance
 costs related to line-of-credit arrangements to continue to be
 presented as an asset regardless of whether there are any
 outstanding borrowings under such arrangement. This additional
 change also was adopted by Alcoa on January 1, 2016. This adoption
 is required on a retrospective basis; therefore, the December 31,
 2015 Consolidated Balance Sheet has been updated to conform to the
 March 31, 2016 presentation. As a result, $51 of debt issuance
 costs (previously reported in Other noncurrent assets) were
 reclassified to the Long-term debt, less amount due within one year
 line item on the December 31, 2015 Consolidated Balance Sheet.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 &lt;u&gt;Issued&lt;/u&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 In March 2016, the FASB issued changes to employee share-based
 payment accounting.&amp;#xA0;Currently, an entity must determine for
 each share-based payment award whether the difference between the
 deduction for tax purposes and the compensation cost recognized for
 financial reporting purposes results in either an excess tax
 benefit or a tax deficiency.&amp;#xA0;Excess tax benefits are
 recognized in additional paid-in capital; tax deficiencies are
 recognized either as an offset to accumulated excess tax benefits,
 if any, or in the income statement. Excess tax benefits are not
 recognized until the deduction reduces taxes payable. The changes
 require all excess tax benefits and tax deficiencies related to
 share-based payment awards to be recognized as income tax expense
 or benefit in the income statement. The tax effects of exercised or
 vested awards should be treated as discrete items in the reporting
 period in which they occur. An entity also should recognize excess
 tax benefits regardless of whether the benefit reduces taxes
 payable in the current period. Additionally, the presentation of
 excess tax benefits related to share-based payment awards in the
 statement of cash flows is changed. Currently, excess tax benefits
 must be separated from other income tax cash flows and classified
 as a financing activity. The changes require excess tax benefits to
 be classified along with other income tax cash flows as an
 operating activity. Also, the changes require cash paid by an
 employer when directly withholding shares for tax-withholding
 purposes to be classified as a financing activity. Currently, there
 is no specific guidance on the classification in the statement of
 cash flows of cash paid by an employer to the tax authorities when
 directly withholding shares for tax-withholding purposes.
 Additionally, for a share-based award to qualify for equity
 classification it cannot partially settle in cash in excess of the
 employer&amp;#x2019;s minimum statutory withholding requirements. The
 changes permit equity classification of share-based awards for
 withholdings up to the maximum statutory tax rates in applicable
 jurisdictions. These changes become effective for Alcoa on January
 1, 2017. Management is currently evaluating the potential impact of
 these changes on the Consolidated Financial Statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In March 2016, the FASB issued changes eliminating the requirement
 for an investor to adjust an equity method investment, results of
 operations, and retained earnings retroactively on a step-by-step
 basis as if the equity method had been in effect during all
 previous periods that the investment had been held as a result of
 an increase in the level of ownership interest or degree of
 influence.&amp;#xA0;Additionally, an entity that has an
 available-for-sale equity security that becomes qualified for the
 equity method of accounting must recognize through earnings the
 unrealized holding gain or loss in accumulated other comprehensive
 income at the date the investment becomes qualified for use of the
 equity method.&amp;#xA0;These changes become effective for Alcoa on
 January 1, 2017.&amp;#xA0;Management is currently evaluating the
 potential impact of these changes on the Consolidated Financial
 Statements.&lt;/p&gt;

 In March 2016, the FASB issued changes to derivative instruments
 designated as hedging instruments.&amp;#xA0;These changes clarify that
 a change in the counterparty to a derivative instrument that has
 been designated as a hedging instrument does not, in and of itself,
 require dedesignation of that hedging relationship provided that
 all other hedge accounting criteria continue to be met. These
 changes become effective for Alcoa on January 1,
 2017.&amp;#xA0;Management does not expect these changes to have a
 material impact on the Consolidated Financial Statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In February 2016, the FASB issued changes to the accounting and
 presentation of leases.&amp;#xA0;These changes require lessees to
 recognize a right of use asset and lease liability on the balance
 sheet for all leases with terms longer than 12 months.&amp;#xA0;For
 leases with a term of 12 months or less, a lessee is permitted to
 make an accounting policy election by class of underlying asset not
 to recognize a right of use asset and lease
 liability.&amp;#xA0;Additionally, when measuring assets and liabilities
 arising from a lease, optional payments should be included only if
 the lessee is reasonably certain to exercise an option to extend
 the lease, exercise a purchase option, or not exercise an option to
 terminate the lease.&amp;#xA0;These changes become effective for Alcoa
 on January 1, 2019.&amp;#xA0;Management is currently evaluating the
 potential impact of these changes on the Consolidated Financial
 Statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In January 2016, the FASB issued changes to equity
 investments.&amp;#xA0;These changes require equity investments (except
 those accounted for under the equity method of accounting or those
 that result in consolidation of the investee) to be measured at
 fair value with changes in fair value recognized in net
 income.&amp;#xA0;However, an entity may choose to measure equity
 investments that do not have readily determinable fair values at
 cost minus impairment, if any, plus or minus changes resulting from
 observable price changes in orderly transactions for the identical
 or similar investment of the same issuer.&amp;#xA0;Additionally, the
 impairment assessment of equity investments without readily
 determinable fair values has been simplified by requiring a
 qualitative assessment to identify impairment. These changes become
 effective for Alcoa on January 1, 2018.&amp;#xA0;Management is
 currently evaluating the potential impact of these changes on the
 Consolidated Financial Statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In July 2015, the FASB issued changes to the subsequent measurement
 of inventory.&amp;#xA0;Currently, an entity is required to measure its
 inventory at the lower of cost or market, whereby market can be
 replacement cost, net realizable value, or net realizable value
 less an approximately normal profit margin.&amp;#xA0;The changes
 require that inventory be measured at the lower of cost and net
 realizable value, thereby eliminating the use of the other two
 market methodologies.&amp;#xA0;Net realizable value is defined as the
 estimated selling prices in the ordinary course of business less
 reasonably predictable costs of completion, disposal, and
 transportation.&amp;#xA0;These changes do not apply to inventories
 measured using LIFO (last-in, first-out) or the retail inventory
 method.&amp;#xA0;Currently, Alcoa applies the net realizable value
 market option to measure non-LIFO inventories at the lower of cost
 or market.&amp;#xA0;These changes become effective for Alcoa on January
 1, 2017.&amp;#xA0;Management has determined that the adoption of these
 changes will not have an impact on the Consolidated Financial
 Statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%"&gt;
 In May 2014, the FASB issued changes to the recognition of revenue
 from contracts with customers.&amp;#xA0;These changes created a
 comprehensive framework for all entities in all industries to apply
 in the determination of when to recognize revenue, and, therefore,
 supersede virtually all existing revenue recognition requirements
 and guidance.&amp;#xA0;This framework is expected to result in less
 complex guidance in application while providing a consistent and
 comparable methodology for revenue recognition.&amp;#xA0;The core
 principle of the guidance is that an entity should recognize
 revenue to depict the transfer of promised goods or
 services.&amp;#xA0;To achieve this principle, an entity should apply
 the following steps: (i) identify the contract(s) with a customer,
 (ii) identify the performance obligations in the contract(s), (iii)
 determine the transaction price, (iv) allocate the transaction
 price to the performance obligations in the contract(s), and (v)
 recognize revenue when, or as, the entity satisfies a performance
 obligation.&amp;#xA0;In August 2015, the FASB deferred the effective
 date by one year, making these changes effective for Alcoa on
 January 1, 2018.&amp;#xA0;In March 2016, the FASB issued amendments to
 clarify the implementation guidance on principal versus agent
 considerations.&amp;#xA0;Management is currently evaluating the
 potential impact of these changes on the Consolidated Financial
 Statements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In August 2014, the FASB issued changes to the disclosure of
 uncertainties about an entity&amp;#x2019;s ability to continue as a
 going concern. Under GAAP, continuation of a reporting entity as a
 going concern is presumed as the basis for preparing financial
 statements unless and until the entity&amp;#x2019;s liquidation becomes
 imminent. Even if an entity&amp;#x2019;s liquidation is not imminent,
 there may be conditions or events that raise substantial doubt
 about the entity&amp;#x2019;s ability to continue as a going concern.
 Because there is no guidance in GAAP about management&amp;#x2019;s
 responsibility to evaluate whether there is substantial doubt about
 an entity&amp;#x2019;s ability to continue as a going concern or to
 provide related note disclosures, there is diversity in practice
 whether, when, and how an entity discloses the relevant conditions
 and events in its financial statements. As a result, these changes
 require an entity&amp;#x2019;s management to evaluate whether there are
 conditions or events, considered in the aggregate, that raise
 substantial doubt about the entity&amp;#x2019;s ability to continue as a
 going concern within one year after the date that financial
 statements are issued. Substantial doubt is defined as an
 indication that it is probable that an entity will be unable to
 meet its obligations as they become due within one year after the
 date that financial statements are issued. If management has
 concluded that substantial doubt exists, then the following
 disclosures should be made in the financial statements:
 (i)&amp;#xA0;principal conditions or events that raised the substantial
 doubt, (ii)&amp;#xA0;management&amp;#x2019;s evaluation of the significance
 of those conditions or events in relation to the entity&amp;#x2019;s
 ability to meet its obligations, (iii)&amp;#xA0;management&amp;#x2019;s
 plans that alleviated the initial substantial doubt or, if
 substantial doubt was not alleviated, management&amp;#x2019;s plans that
 are intended to at least mitigate the conditions or events that
 raise substantial doubt, and (iv)&amp;#xA0;if the latter in
 (iii)&amp;#xA0;is disclosed, an explicit statement that there is
 substantial doubt about the entity&amp;#x2019;s ability to continue as a
 going concern. These changes become effective for Alcoa for the
 2016 annual financial statements. Management has determined that
 the adoption of these changes will not have an impact on the
 Consolidated Financial Statements. Subsequent to adoption, this
 guidance will need to be applied by management at the end of each
 annual period and interim period therein to determine what, if any,
 impact there will be on the Consolidated Financial Statements in a
 given reporting period.&lt;/p&gt;

 Consolidated Financial Statements of Alcoa Inc. and its
 subsidiaries (&amp;#x201C;Alcoa&amp;#x201D; or the &amp;#x201C;Company&amp;#x201D;) are
 unaudited. These Consolidated Financial Statements include all
 adjustments, consisting of only normal recurring adjustments,
 considered necessary by management to fairly state the
 Company&amp;#x2019;s results of operations, financial position, and cash
 flows. The results reported in these Consolidated Financial
 Statements are not necessarily indicative of the results that may
 be expected for the entire year. The 2015 year-end balance sheet
 data was derived from audited financial statements but does not
 include all disclosures required by accounting principles generally
 accepted in the United States of America (GAAP). This Form 10-Q
 report should be read in conjunction with Alcoa&amp;#x2019;s Annual
 Report on Form 10-K for the year ended December 31, 2015, which
 includes all disclosures required by GAAP. Certain amounts in
 previously issued financial statements were reclassified to conform
 to the current period presentation (see Note B).&lt;/p&gt;

 &lt;b&gt;L. Receivables&lt;/b&gt; &amp;#x2013; Alcoa has an arrangement with three
 financial institutions to sell certain customer receivables without
 recourse on a revolving basis. The sale of such receivables is
 completed through the use of a bankruptcy remote special purpose
 entity, which is a consolidated subsidiary of Alcoa. This
 arrangement provides for minimum funding of $200 up to a maximum of
 $500 for receivables sold. On March 30, 2012, Alcoa initially sold
 $304 of customer receivables in exchange for $50 in cash and $254
 of deferred purchase price under this arrangement. Alcoa has
 received additional net cash funding of $300 for receivables sold
 ($1,358 in draws and $1,058 in repayments) since the
 program&amp;#x2019;s inception. Draws and repayments in the 2016 first
 quarter were $100 and $0, respectively.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 As of March 31, 2016 and December 31, 2015, the deferred purchase
 price receivable was $210 and $249, respectively, which was
 included in Other receivables on the accompanying Consolidated
 Balance Sheet.&amp;#xA0;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.&amp;#xA0;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.&amp;#xA0;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The gross amount of receivables sold and total cash collected under
 this program since its inception was $26,055 and $25,495,
 respectively.&amp;#xA0;Alcoa services the customer receivables for the
 financial institutions at market rates; therefore, no servicing
 asset or liability was recorded.&lt;/p&gt;

 &lt;b&gt;D. Restructuring and Other Charges&lt;/b&gt;&amp;#xA0;&amp;#x2013; In the first quarter
 of 2016, Alcoa recorded Restructuring and other charges of $93 ($61
 after-tax and noncontrolling interest), which were comprised of the
 following components: $60 ($39 after-tax) related to the 2015
 announced permanent closure of the Warrick smelter; $19 ($14
 after-tax and noncontrolling interest) for layoff costs, including
 the separation of approximately 560 employees (500 in the
 Engineered Products and Solutions segment, 30 in the Primary Metals
 segment, and 30 in the Global Rolled Products segment); $18 ($11
 after-tax and noncontrolling interest) related to the curtailments
 of the Point Comfort refinery and Wenatchee smelter; and $4 ($3
 after-tax and noncontrolling interest) for the reversal of a number
 of small layoff reserves related to prior periods and other
 miscellaneous items.&lt;/p&gt;

 In 2016, costs related to the closure and curtailment actions
 included $70 for accelerated depreciation as the Warrick facility
 continued to operate through March 2016, $27 in other exit costs
 primarily for contract terminations, and $19 for the reversal of
 previously accrued severance costs that will not be
 incurred.&amp;#xA0;Additionally in the first quarter of 2016,
 inventories were written down to their net realizable value,
 resulting in a charge of $3 ($2 after-tax), which was recorded in
 Cost of goods sold on the accompanying Statement of Consolidated
 Operations.&lt;/p&gt;

 In the first quarter of 2015, Alcoa recorded Restructuring and
 other charges of $177 ($158 after-tax and noncontrolling interest)
 which were comprised of the following components: $149 ($142
 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; $16
 ($11 after-tax) for the separation of approximately 680 employees
 (Primary Metals segment) and supplier contract-related costs
 associated with the decision to temporarily curtail the remaining
 capacity (74,000 metric-tons-per-year) at the S&amp;#xE3;o Lu&amp;#xED;s
 smelter in Brazil; $13 ($8 after-tax and noncontrolling interest)
 for layoff costs, including the separation of approximately 210
 employees (80 in the Engineered Products and Solutions segment, 40
 in the Transportation and Construction Solutions segment, 30 in the
 Global Rolled Products segment, and 60 in Corporate); a net charge
 of $6 ($3 after-tax and noncontrolling interest) for other
 miscellaneous items; and $7 ($6 after-tax) for the reversal of a
 number of small layoff reserves related to prior periods.&lt;/p&gt;

 As of March 31, 2016, approximately 320 of the 560 employees
 associated with 2016 restructuring programs, approximately 2,750 of
 the 5,050 (previously 5,200 &amp;#x2013; updated to reflect employees
 accepting other positions within Alcoa and natural attrition)
 employees associated with 2015 restructuring programs, and
 approximately 2,590 of the 2,820 employees (previously 2,870
 &amp;#x2013; updated to reflect employees accepting other positions
 within Alcoa and natural attrition) associated with 2014
 restructuring programs were separated. Most of the remaining
 separations for the 2016, 2015, and 2014 restructuring programs are
 expected to be completed by the end of 2016.&lt;/p&gt;

 &lt;td valign="top" align="left"&gt;Other includes reversals of
 previously recorded restructuring charges and the effects of
 foreign currency translation. In the 2016 three-month period, Other
 for exit costs also included a reclassification of $7 in asset
 retirement obligations, as this liability was included in
 Alcoa&amp;#x2019;s separate reserves for asset retirement obligations.
 In 2015, Other for layoff costs also included a reclassification of
 $35 in pension and/or other postretirement benefit costs, as these
 obligations were included in Alcoa&amp;#x2019;s separate liabilities for
 pension and other postretirement obligations. Additionally, in
 2015, Other for exit costs also included a reclassification of $76
 and $86 in asset retirement obligations and environmental
 obligations, respectively, as these liabilities were included in
 Alcoa&amp;#x2019;s separate reserves for asset retirement obligations
 and environmental remediation.&lt;/td&gt;

 special separation benefit payments and ongoing site remediation
 work.&lt;/p&gt;

 On June 5, 2015, Alcoa World Alumina LLC (&amp;#x201C;AWA&amp;#x201D;) and
 St. Croix Alumina, L.L.C. (&amp;#x201C;SCA&amp;#x201D;) filed a complaint in
 Delaware Chancery Court for a declaratory judgment and injunctive
 relief to resolve a dispute between Alcoa and Glencore Ltd.
 (&amp;#x201C;Glencore&amp;#x201D;) with respect to claimed obligations under
 a 1995 asset purchase agreement between Alcoa and
 Glencore.&amp;#xA0;The dispute arose from Glencore&amp;#x2019;s demand that
 Alcoa indemnify it for liabilities it may have to pay to Lockheed
 Martin (&amp;#x201C;Lockheed&amp;#x201D;) related to the St. Croix alumina
 refinery.&amp;#xA0;Lockheed had earlier filed suit against Glencore in
 federal court in New York seeking indemnity for liabilities it had
 incurred and would incur to the U.S. Virgin Islands to remediate
 certain properties at the refinery property and claimed that
 Glencore was required by an earlier, 1989 purchase agreement to
 indemnify it.&amp;#xA0;Glencore had demanded that Alcoa indemnify and
 defend it in the Lockheed case and threatened to claim against
 Alcoa in the New York action despite exclusive jurisdiction for
 resolution of disputes under the 1995 purchase agreement being in
 Delaware.&amp;#xA0;After Glencore conceded that it was not seeking to
 add Alcoa to the New York action, AWA and SCA dismissed their
 complaint in the Chancery Court case and on August 6, 2015 filed a
 complaint for declaratory judgment in Delaware Superior
 Court.&amp;#xA0;AWA and SCA filed a motion for judgment on the
 pleadings on September 16, 2015. Glencore answered AWA&amp;#x2019;s and
 SCA&amp;#x2019;s complaint and asserted counterclaims on August 27,
 2015, and on October 2, 2015 filed its own motion for judgment on
 the pleadings.&amp;#xA0;Argument on the parties&amp;#x2019; motions was held
 by the court on December 7, 2015, and by order dated February 8,
 2016, the court granted Alcoa&amp;#x2019;s motion and denied
 Glencore&amp;#x2019;s motion, resulting in Alcoa not being liable to
 indemnify Glencore for the Lockheed action. The decision also
 leaves for pretrial discovery and possible summary judgment or
 trial Glencore&amp;#x2019;s claims for costs and fees it incurred in
 defending and settling an earlier Superfund action brought against
 Glencore by the Government of the Virgin Islands. On February 17,
 2016, Glencore filed notice of its application for interlocutory
 appeal of the February&amp;#xA0;8 ruling. AWA and SCA filed an
 opposition to that application on February 29, 2016. On March 10,
 2016, the court denied Glencore&amp;#x2019;s motion for interlocutory
 appeal and on the same day entered judgment on claims other than
 Glencore&amp;#x2019;s claims for costs and fees it incurred in defending
 and settling the earlier Superfund action brought against Glencore
 by the Government of the Virgin Islands. On March 29, 2016,
 Glencore filed a withdrawal of its notice of interlocutory appeal
 and also noted its intent to appeal the court&amp;#x2019;s March 10,
 2016 judgment. At this time, the Company is unable to reasonably
 predict an outcome for this matter.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 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 (&amp;#x201C;204/1999&amp;#x201D;). 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 &amp;#x201C;state aid.&amp;#x201D; 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).&amp;#xA0;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 (&amp;#x20AC;85), including interest.&amp;#xA0;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 (&amp;#x201C;44/2012&amp;#x201D;) came into effect, changing the
 method to calculate the drawback. On February 21, 2013, Alcoa
 received a revised request letter from CCSE demanding Alcoa&amp;#x2019;s
 subsidiary, Alcoa Trasformazioni S.r.l., make a payment in the
 amount of $97 (&amp;#x20AC;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 (&amp;#x20AC;76). Alcoa rejected that demand and
 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
 that date, the Administrative Court listened to Alcoa&amp;#x2019;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&amp;#x2019;s
 September 2, 2014 decision; however, a date for the hearing has not
 been scheduled. Management recorded a partial reserve for this
 matter of $37 (&amp;#x20AC;34) during the quarter ended December 31,
 2015 (see Note N in the Company&amp;#x2019;s Annual Report on Form 10-K
 for the year ended December 31, 2015). At this time, the Company is
 unable to reasonably predict an outcome for this matter.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Alcoa participates in environmental assessments and cleanups at
 more than 100 locations.&amp;#xA0;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 A liability is recorded for environmental remediation when a
 cleanup program becomes probable and the costs can be reasonably
 estimated.&amp;#xA0;As assessments and cleanups proceed, the liability
 is adjusted based on progress made in determining the extent of
 remedial actions and related costs.&amp;#xA0;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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Alcoa&amp;#x2019;s remediation reserve balance was $605 and $604 at
 March 31, 2016 and December 31, 2015 (of which $47 and $50 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In the 2016 first quarter, the remediation reserve was increased by
 $7 associated with a number of sites.&amp;#xA0;The changes to the
 remediation reserve in the 2016 first quarter were recorded in Cost
 of goods sold on the accompanying Statement of Consolidated
 Operations.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Payments related to remediation expenses applied against the
 reserve were $11 in the first quarter.&amp;#xA0;This amount includes
 expenditures currently mandated, as well as those not required by
 any regulatory authority or third party.&amp;#xA0;In the 2016 first
 quarter, the change in the reserve also reflects an increase of $5
 due to the effects of foreign currency translation.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 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.&lt;/p&gt;

 The following discussion provides details regarding the current
 status of certain significant reserves related to current or former
 Alcoa sites.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 &lt;b&gt;Massena West, NY&amp;#x2014;&lt;/b&gt;Alcoa has an ongoing remediation
 project related to the Grasse River, which is adjacent to
 Alcoa&amp;#x2019;s Massena plant site.&amp;#xA0;Many years ago, it was
 determined that sediments and fish in the river contain varying
 levels of polychlorinated biphenyls (PCBs).&amp;#xA0;The project, which
 was selected by the U.S. Environmental Protection Agency (EPA) in a
 Record of Decision (ROD) issued in April 2013, is aimed at capping
 PCB contaminated sediments with concentration in excess of one part
 per million in the main channel of the river and dredging PCB
 contaminated sediments in the near-shore areas where total PCBs
 exceed one part per million.&amp;#xA0;At March 31, 2016 and December
 31, 2015, the reserve balance associated with this matter was $233
 and $234, respectively.&amp;#xA0;Alcoa is in the planning and design
 phase, which is expected to be completed in 2017.&amp;#xA0;Subsequently
 in 2017, the actual remediation fieldwork is expected to commence
 and take approximately four years.&amp;#xA0;The majority of the project
 funding is expected to be spent between 2017 and 2021.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 &lt;b&gt;Sherwin, TX&amp;#x2014;&lt;/b&gt;In connection with the sale of the Sherwin
 alumina refinery, which was required to be divested as part of the
 Reynolds merger in 2000, Alcoa agreed to retain responsibility for
 the remediation of the then existing environmental conditions, as
 well as a pro rata share of the final closure of the active bauxite
 residue waste disposal areas (known as the Copano facility).
 Alcoa&amp;#x2019;s share of the closure costs is proportional to the
 total period of operation of the active waste disposal areas. At
 March 31, 2016 and December 31, 2015, the reserve balance
 associated with Sherwin was $30. Approximately half of the project
 funding is expected to be spent through 2019. The remainder is not
 expected to be spent in the foreseeable future as it is dependent
 upon the operating life of the active waste disposal areas.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 &lt;b&gt;East St. Louis, IL&amp;#x2014;&lt;/b&gt;Alcoa has an ongoing remediation
 project related to an area used for the disposal of bauxite residue
 from former alumina refining operations. The project, which was
 selected by the EPA in a ROD issued in July 2012, is aimed at
 implementing a soil cover over the affected area. On November 1,
 2013, the U.S. Department of Justice lodged a consent decree on
 behalf of the EPA for Alcoa to conduct the work outlined in the
 ROD. This consent decree was entered as final in February 2014 by
 the U.S. Department of Justice. As a result, Alcoa began
 construction in March 2014; this project is expected to be
 completed by the end of June 2016 (Alcoa has a second project in
 East St. Louis that is separate from the matter presented herein on
 which Alcoa is expecting an EPA decision in 2016 &amp;#x2013; any
 resulting liability is not expected to be material). At March 31,
 2016 and December 31, 2015, the reserve balance associated with
 this matter was $7 and $8, respectively.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 &lt;b&gt;Fusina and Portovesme, Italy&amp;#x2014;&lt;/b&gt;In 1996, Alcoa acquired
 the Fusina smelter and rolling operations and the Portovesme
 smelter, both of which are owned by Alcoa&amp;#x2019;s subsidiary Alcoa
 Trasformazioni S.r.l. (&amp;#x201C;Trasformazioni&amp;#x201D;), from Alumix,
 an entity owned by the Italian Government. At the time of the
 acquisition, Alumix indemnified Alcoa for pre-existing
 environmental contamination at the sites. In 2004, the Italian
 Ministry of Environment and Protection of Land and Sea (MOE) issued
 orders to Trasformazioni and Alumix for the development of a
 clean-up plan related to soil contamination in excess of allowable
 limits under legislative decree and to institute emergency actions
 and pay natural resource damages. Trasformazioni appealed the
 orders and filed suit against Alumix, among others, seeking
 indemnification for these liabilities under the provisions of the
 acquisition agreement. In 2009, Ligestra S.r.l.
 (&amp;#x201C;Ligestra&amp;#x201D;), Alumix&amp;#x2019;s successor, and
 Trasformazioni agreed to a stay of the court proceedings while
 investigations were conducted and negotiations advanced towards a
 possible settlement.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 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).&amp;#xA0;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.&amp;#xA0;The agreement was contingent
 upon final acceptance of the remediation project by the
 MOE.&amp;#xA0;As a result of entering into this agreement, Alcoa
 increased the reserve by $12 in 2009 for Fusina.&amp;#xA0;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.&amp;#xA0;In October 2013, the MOE
 approved the project submitted by Alcoa, resulting in no adjustment
 to the reserve.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 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. The agreement
 includes both a soil and groundwater remediation project estimated
 to cost $33 (&amp;#x20AC;24) and requires payments of $25 (&amp;#x20AC;18) to
 the MOE for emergency action and natural resource damages. The
 remediation projects are slated to begin as soon as Alcoa receives
 final approval from the Ministry of Infrastructure. Based on the
 final agreement with Ligestra, Alcoa&amp;#x2019;s share of all costs and
 payments is $17 (&amp;#x20AC;12), of which $9 (&amp;#x20AC;6) related to the
 damages will be paid annually over a 10-year period, which began in
 April 2014, and was previously fully reserved.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Separately, in 2009, due to additional information derived from the
 site investigations conducted at Portovesme, Alcoa increased the
 reserve by $3.&amp;#xA0;In November 2011, Trasformazioni and Ligestra
 reached an agreement for settlement of the liabilities related to
 Portovesme, similar to the one for Fusina.&amp;#xA0;A proposed soil
 remediation project for Portovesme was formally presented to the
 MOE in June 2012.&amp;#xA0;Neither the agreement with Ligestra nor the
 proposal to the MOE resulted in a change to the reserve for
 Portovesme.&amp;#xA0;In November 2013, the MOE rejected the proposed
 soil remediation project and requested a revised project be
 submitted.&amp;#xA0;In May 2014, Trasformazioni and Ligestra submitted
 a revised soil remediation project that addressed certain
 stakeholders&amp;#x2019; 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.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%"&gt;
 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.&amp;#xA0;Trasformazioni
 and Ligestra submitted the further revised soil remediation project
 in February 2015.&amp;#xA0;As a result, Alcoa increased the reserve by
 $7 in March 2015 to reflect the increase in the estimated costs of
 the project.&amp;#xA0;In October 2015, Alcoa received a final
 ministerial decree approving the February 2015 revised soil
 remediation project.&amp;#xA0;Work on the soil remediation project will
 commence in 2016 and is expected to be completed in
 2019.&amp;#xA0;Alcoa and Ligestra are now working on a final
 groundwater remediation project, which will be submitted to the MOE
 for review during 2016.&amp;#xA0;The ultimate outcome of this matter
 may result in a change to the existing reserve for Portovesme.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 &lt;b&gt;Baie Comeau, Quebec, Canada&amp;#x2014;&lt;/b&gt;In August 2012, Alcoa
 presented an analysis of remediation alternatives to the Quebec
 Ministry of Sustainable Development, Environment, Wildlife and
 Parks (MDDEP), in response to a previous request, related to known
 PCBs and polycyclic aromatic hydrocarbons (PAHs) contained in
 sediments of the Anse du Moulin bay.&amp;#xA0;As such, Alcoa increased
 the reserve for Baie Comeau by $25 in 2012 to reflect the estimated
 cost of Alcoa&amp;#x2019;s recommended alternative, consisting of both
 dredging and capping of the contaminated sediments. In July 2013,
 Alcoa submitted the Environmental Impact Assessment for the project
 to the MDDEP. The MDDEP notified Alcoa that the project as it was
 submitted was approved and a final ministerial decree was issued in
 July 2015. As a result, no further adjustment to the reserve was
 required in 2015. The decree provides final approval for the
 project and allows Alcoa to start work on the final project design,
 which is expected to be completed in 2016 with construction on the
 project expected to begin in 2017. Completion of the final project
 design and bidding of the project may result in additional
 liability in a future period.&lt;/p&gt;

 &lt;b&gt;Mosj&amp;#xF8;en, Norway&amp;#x2014;&lt;/b&gt;In September 2012, Alcoa
 presented an analysis of remediation alternatives to the Norwegian
 Environmental Agency (NEA) (formerly the Norwegian Climate and
 Pollution Agency, or &amp;#x201C;Klif&amp;#x201D;), in response to a previous
 request, related to known PAHs in the sediments located in the
 harbor and extending out into the fjord. As such, Alcoa increased
 the reserve for Mosj&amp;#xF8;en by $20 in 2012 to reflect the
 estimated cost of the baseline alternative for dredging of the
 contaminated sediments. A proposed project reflecting this
 alternative was formally presented to the NEA in June 2014, and was
 resubmitted in late 2014 to reflect changes by the NEA. The revised
 proposal did not result in a change to the reserve for
 Mosj&amp;#xF8;en.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In April 2015, the NEA notified Alcoa that the revised project was
 approved and required submission of the final project design before
 issuing a final order.&amp;#xA0;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.&amp;#xA0;As a result, Alcoa increased the reserve for
 Mosj&amp;#xF8;en by $11 in June 2015 to reflect the estimated cost of
 the wharf stabilization. Also in June 2015, the NEA issued a final
 order approving the project as well as the final project design. In
 September 2015, Alcoa increased the reserve by $1 to reflect the
 potential need (based on prior experience with similar projects) to
 perform additional dredging if the results of sampling, which is
 required by the order, don&amp;#x2019;t achieve the required cleanup
 levels. Project construction will commence in 2016 and is expected
 to be completed by the end of 2017.&lt;/p&gt;

 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&amp;#x2019;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&amp;#x2019;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&amp;#x2019;s National Court.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Additionally, following a corporate income tax audit of the same
 Spanish tax group for the 2006 through 2009 tax years,
 Spain&amp;#x2019;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&amp;#x2019;s Central Tax Administrative Court, which was denied in
 January 2015. The Company filed an appeal of this second assessment
 in Spain&amp;#x2019;s National Court in March 2015.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The combined assessments (remeasured for a tax rate change enacted
 in November 2014) total $273 (&amp;#x20AC;241), including interest. The
 Company believes it has meritorious arguments to support its tax
 position and intends to vigorously litigate the assessments through
 Spain&amp;#x2019;s court system.&amp;#xA0;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.&lt;/p&gt;

 In March 2013, Alcoa&amp;#x2019;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.&amp;#xA0;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 S&amp;#xE3;o Lu&amp;#xED;s 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.&amp;#xA0;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.&amp;#xA0;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.&amp;#xA0;Separately from
 AWAB&amp;#x2019;s administrative appeal, in June 2015, new tax law was
 enacted repealing the provisions in the tax code that were the
 basis for the RFB assessing a 50% penalty in this matter. As such,
 the estimated range of reasonably possible loss is $0 to $29
 (R$103), whereby the maximum end of the range represents the
 portion of the disallowed credits applicable to the export sales
 and excludes the 50% penalty. Additionally, the estimated range of
 disallowed credits related to AWAB&amp;#x2019;s fixed assets is $0 to
 $32 (R$117), which would increase the net carrying value of
 AWAB&amp;#x2019;s fixed assets if ultimately disallowed. It is
 management&amp;#x2019;s opinion that the allegations have no basis;
 however, at this time, management is unable to reasonably predict
 an outcome for this matter.&lt;/p&gt;

 Between 2000 and 2002, Alcoa Alum&amp;#xED;nio (Alum&amp;#xED;nio) sold
 approximately 2,000 metric tons of metal per month from its
 Po&amp;#xE7;os de Caldas facility, located in the State of Minas Gerais
 (the &amp;#x201C;State&amp;#x201D;), to Alfio, a customer also located in the
 State.&amp;#xA0;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, Alum&amp;#xED;nio received an assessment
 from State auditors on the theory that Alum&amp;#xED;nio should be
 jointly and severally liable with Alfio for the unpaid VAT. In June
 2003, the administrative tribunal found Alum&amp;#xED;nio liable, and
 Alum&amp;#xED;nio filed a judicial case in the State in February 2004
 contesting the finding.&amp;#xA0;In May 2005, the Court of First
 Instance found Alum&amp;#xED;nio solely liable, and a panel of a State
 appeals court confirmed this finding in April
 2006.&amp;#xA0;Alum&amp;#xED;nio filed a special appeal to the Superior
 Tribunal of Justice (STJ) in Brasilia (the federal capital of
 Brazil) later in 2006.&amp;#xA0;In 2011, the STJ (through one of its
 judges) reversed the judgment of the lower courts, finding that
 Alum&amp;#xED;nio should neither be solely nor jointly and severally
 liable with Alfio for the VAT, which ruling was then appealed by
 the State.&amp;#xA0;In August 2012, the STJ agreed to have the case
 reheard before a five-judge panel.&amp;#xA0;A decision from this panel
 is pending, but additional appeals are likely.&amp;#xA0;At March 31,
 2016, the assessment totaled $38 (R$137), including penalties and
 interest.&amp;#xA0;While the Company believes it has meritorious
 defenses, the Company is unable to reasonably predict an
 outcome.&lt;/p&gt;

 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&amp;#x2019;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.&lt;/p&gt;

 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.&amp;#xA0;The joint venture is owned
 74.9% by the Saudi Arabian Mining Company (known as
 &amp;#x201C;Ma&amp;#x2019;aden&amp;#x201D;) 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.&amp;#xA0;Alcoa accounts
 for its investment in the joint venture under the equity
 method.&amp;#xA0;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&amp;#x2019;s partners&amp;#x2019; ownership interests.
 Originally, it was estimated that Alcoa&amp;#x2019;s total equity
 investment in the joint venture would be approximately $1,100, of
 which Alcoa has contributed $982, including $1 in the 2016 first
 quarter. Based on changes to both the project&amp;#x2019;s capital
 investment and equity and debt structure from the initial plans,
 the estimated $1,100 equity contribution may be reduced. As of
 March 31, 2016 and December 31, 2015, the carrying value of
 Alcoa&amp;#x2019;s investment in this project was $906 and $928,
 respectively.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The smelting and rolling mill companies have project financing
 totaling $4,311 (reflects principal repayments made through March
 31, 2016), of which $1,082 represents Alcoa&amp;#x2019;s share (the
 equivalent of Alcoa&amp;#x2019;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&amp;#x2019;aden issued similar guarantees for its 74.9% interest).
 Alcoa&amp;#x2019;s guarantees for the smelting and rolling mill
 companies cover total debt service requirements of $142 in
 principal and up to a maximum of approximately $40 in interest per
 year (based on projected interest rates). At March 31, 2016 and
 December&amp;#xA0;31, 2015, the combined fair value of the guarantees
 was $7 in both periods, which was included in Other noncurrent
 liabilities and deferred credits on the accompanying Consolidated
 Balance Sheet.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The mining and refining company has project financing totaling
 $2,232, of which $560 represents AWAC&amp;#x2019;s 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&amp;#x2019;aden issued
 similar guarantees for its 74.9% interest). Alcoa&amp;#x2019;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 March 31, 2016 and December&amp;#xA0;31, 2015, the combined
 fair value of the guarantees was $3 in both periods, 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.&lt;/p&gt;

 In 2004, AofA 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
 AofA&amp;#x2019;s refineries in Western Australia. AofA 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&amp;#x2019;s capacity is planned at this time. In late 2011,
 the consortium initiated a three-year equity call plan to improve
 its capitalization structure. The plan required AofA 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 AofA to contribute
 $30 (A$36) through mid 2016, of which $20 (A$27) was made through
 March 31, 2016, including $3 (A$5) in the 2016 first quarter. In
 addition to its equity ownership, AofA has an agreement to purchase
 gas transmission services from the DBNGP. At March 31, 2016, Alcoa
 has an asset of $284 (A$369) representing prepayments made under
 the agreement for future gas transmission services. AofA&amp;#x2019;s
 maximum exposure to loss on the investment and the related contract
 is approximately $400 (A$520) as of March 31, 2016.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In April 2016, AofA completed the sale of its 20% interest in DBP,
 the owner and operator of the DBNGP for $154 (A$205).&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In April 2015, AofA secured a new 12-year gas supply agreement to
 power its three alumina refineries in Western Australia beginning
 in July 2020.&amp;#xA0;This agreement was conditional on the completion
 of a third-party acquisition of the related energy assets from the
 then-current owner, which occurred in June 2015.&amp;#xA0;The terms of
 AofA&amp;#x2019;s gas supply agreement require a prepayment of $500 to
 be made in two installments.&amp;#xA0;The first installment of $300 was
 made in the second quarter of 2015 and the second installment of
 $200 was paid in April 2016. At March 31, 2016 and December 31,
 2015, an asset of $304 (A$395) and $288 (A$395), respectively, was
 included in Other noncurrent assets on the accompanying
 Consolidated Balance Sheet.&lt;/p&gt;

 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&amp;#x2019;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&lt;/p&gt;

 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&amp;#x2019;s exposure to the risks of changing commodity prices,
 interest rates, and foreign currency exchange rates.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Alcoa&amp;#x2019;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&amp;#x2019;s Board of Directors on the
 scope of its activities.&lt;/p&gt;

 The aluminum, energy, interest rate, and foreign exchange contracts
 are held for purposes other than trading.&amp;#xA0;They are used
 primarily to mitigate uncertainty and volatility, and to cover
 underlying exposures.&amp;#xA0;Alcoa is not involved in trading
 activities for energy, weather derivatives, or other nonexchange
 commodity trading activities.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 A number of Alcoa&amp;#x2019;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&amp;#x2019;s Consolidated Financial Statements for all
 periods.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 For the aluminum contracts classified as Level 1, the total fair
 value of derivatives recorded as assets and liabilities was $4 and
 $35 and $8 and $58 at March 31, 2016 and December 31, 2015,
 respectively.&amp;#xA0;These contracts were entered into to either
 hedge forecasted sales or purchases of aluminum in order to manage
 the associated aluminum price risk.&amp;#xA0;Certain of these contracts
 are designated as hedging instruments, either fair value or cash
 flow, and the remaining are not designated as such.&amp;#xA0;Combined,
 Alcoa recognized a net gain of $2 and $26 in the first quarter of
 2016 and 2015, respectively, in Sales on the accompanying Statement
 of Consolidated Operations related to these aluminum contracts.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 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.&amp;#xA0;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

 and two of the embedded aluminum derivatives and the embedded

 The following section describes the valuation methodologies used by
 Alcoa to measure its Level 3 derivative instruments at fair
 value.&amp;#xA0;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.&amp;#xA0;Alcoa uses a discounted cash flow model to fair value
 all Level 3 derivative instruments.&amp;#xA0;Where appropriate, the
 description below includes the key inputs to those models and any
 significant assumptions.&amp;#xA0;These valuation models are reviewed
 and tested at least on an annual basis.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 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).&amp;#xA0;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.&amp;#xA0;Additionally, for periods beyond the term of
 quoted market prices for energy, management has developed a forward
 curve based on independent consultant market research.&amp;#xA0;Where
 appropriate, valuations are adjusted for various factors such as
 liquidity, bid/offer spreads, and credit considerations.&amp;#xA0;Such
 adjustments are generally based on available market evidence (Level
 2). In the absence of such evidence, management&amp;#x2019;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).&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Alcoa has embedded derivatives in two power contracts that index
 the price of power to the LME price of aluminum.&amp;#xA0;Additionally,
 Alcoa has embedded derivatives in 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.&amp;#xA0;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 Midwest premium curve.&amp;#xA0;Significant increases or
 decreases in the actual LME price beyond 10 years and/or the
 Midwest premium beyond 5 years would result in a higher or lower
 fair value measurement.&amp;#xA0;An increase in actual LME price and/or
 the Midwest premium over the inputs used in the valuation models
 will result in a higher cost of power and a corresponding decrease
 to the derivative asset or increase to the derivative
 liability.&amp;#xA0;The embedded derivatives have been designated as
 cash flow hedges of forward sales of aluminum.&amp;#xA0;Unrealized
 gains and losses were included in Other comprehensive loss on the
 accompanying Consolidated Balance Sheet while realized gains and
 losses were included in Sales on the accompanying Statement of
 Consolidated Operations.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Also, Alcoa has a power contract separate from above that contains
 an LME-linked embedded derivative.&amp;#xA0;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.&amp;#xA0;Significant increases or decreases
 in the LME price would result in a higher or lower fair value
 measurement.&amp;#xA0;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.&amp;#xA0;This
 embedded derivative did not qualify for hedge accounting
 treatment.&amp;#xA0;Unrealized gains and losses from the embedded
 derivative were included in Other expenses (income), net on the
 accompanying Statement of Consolidated Operations while realized
 gains and losses were included in Cost of goods sold on the
 accompanying Statement of Consolidated Operations as electricity
 purchases were made under the contract.&amp;#xA0;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.&amp;#xA0;This deferred credit is recognized in Other expenses
 (income), net on the accompanying Statement of Consolidated
 Operations as power is received over the life of the contract.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Additionally, Alcoa has a natural gas supply contract, which has an
 LME-linked ceiling.&amp;#xA0;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.&amp;#xA0;Any change
 in the interrelationship would result in a higher or lower fair
 value measurement.&amp;#xA0;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.&amp;#xA0;An
 increase in oil prices with no similar increase in the LME price
 would limit the increase of the price paid for natural
 gas.&amp;#xA0;This embedded derivative did not qualify for hedge
 accounting treatment.&amp;#xA0;Unrealized gains and losses from the
 embedded derivative were included in Other expenses (income), net
 on the accompanying Statement of Consolidated Operations while
 realized gains and losses were included in Cost of goods sold on
 the accompanying Statement of Consolidated Operations as gas
 purchases were made under the contract.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 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.&amp;#xA0;Management uses market prices, historical
 relationships, and forecast services to determine fair
 value.&amp;#xA0;Significant increases or decreases in any of these
 inputs would result in a lower or higher fair value
 measurement.&amp;#xA0;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.&amp;#xA0;This
 embedded derivative did not qualify for hedge accounting
 treatment.&amp;#xA0;Unrealized gains and losses were included in Other
 expenses (income), net on the accompanying Statement of
 Consolidated Operations while realized gains and losses were
 included in Cost of goods sold on the accompanying Statement of
 Consolidated Operations as electricity purchases were made under
 the contract.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 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 September 2016.&amp;#xA0;Beyond the
 term where market information is available, management has
 developed a forward curve, for valuation purposes, based on
 independent consultant market research.&amp;#xA0;Significant increases
 or decreases in the power market may result in a higher or lower
 fair value measurement.&amp;#xA0;Lower prices in the power market would
 cause a decrease in the derivative asset.&amp;#xA0;The derivative
 contract has been designated as a cash flow hedge of future
 purchases of electricity.&amp;#xA0;Unrealized gains and losses on this
 contract were recorded in Other comprehensive loss on the
 accompanying Consolidated Balance Sheet.&amp;#xA0;Once the designated
 hedge period begins in September 2016, realized gains and losses
 will be recorded in Cost of goods sold as electricity purchases are
 made under the power contract.&lt;/p&gt;

 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).&amp;#xA0;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.&amp;#xA0;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.&lt;/p&gt;

 &lt;b&gt;Embedded aluminum derivatives.&lt;/b&gt; Alcoa has entered into energy
 supply contracts that contain pricing provisions related to the LME
 aluminum price.&amp;#xA0;The LME-linked pricing features are considered
 embedded derivatives.&amp;#xA0;Five of these embedded derivatives have
 been designated as cash flow hedges of forward sales of
 aluminum.&amp;#xA0;At March 31, 2016 and December 31, 2015, these
 embedded aluminum derivatives hedge forecasted aluminum sales of
 3,246 kmt and 3,307 kmt, respectively.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 &lt;b&gt;Cash and cash equivalents, Restricted cash, Short-term
 borrowings, and Commercial paper.&lt;/b&gt; The carrying amounts
 approximate fair value because of the short maturity of the
 instruments.&amp;#xA0;The fair value amounts for Cash and cash
 equivalents, Restricted cash, and Commercial paper were classified
 in Level 1, and Short-term borrowings were classified in Level
 2.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 &lt;b&gt;Noncurrent receivables.&lt;/b&gt; The fair value of noncurrent
 receivables was based on anticipated cash flows, which approximates
 carrying value, and was classified in Level 2 of the fair value
 hierarchy.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 &lt;b&gt;Available-for-sale securities.&lt;/b&gt; The fair value of such
 securities was based on quoted market prices.&amp;#xA0;These financial
 instruments consist of exchange-traded fixed income and equity
 securities, which are carried at fair value and were classified in
 Level 1 of the fair value hierarchy.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 &lt;b&gt;Contingent payment related to an acquisition&lt;/b&gt;.&amp;#xA0;The fair
 value was based on the net present value of expected future cash
 flows and was classified in Level 3 of the fair value
 hierarchy.&lt;/p&gt;

 &lt;b&gt;Long-term debt due within one year and Long-term debt, less
 amount due within one year.&lt;/b&gt; The fair value was based on quoted
 market prices for public debt and on interest rates that are
 currently available to Alcoa for issuance of debt with similar
 terms and maturities for non-public debt.&amp;#xA0;The fair value
 amounts for all Long-term debt were classified in Level 2 of the
 fair value hierarchy.&amp;#xA0;In the first quarter of 2016, $750 of
 5.55% Notes with a maturity date of February 2017 were reclassified
 from Long-term debt, less amount due within one year to Long-term
 debt due within one year on the accompanying Consolidated Balance
 Sheet.&lt;/p&gt;

 &lt;b&gt;J. Earnings Per Share&lt;/b&gt; &amp;#x2014; Basic earnings per share (EPS)
 amounts are computed by dividing earnings, after the deduction of

 shares outstanding.&amp;#xA0;Diluted EPS amounts assume the issuance of

 In the first quarter of 2016, 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 available to Alcoa common
 shareholders.&amp;#xA0;As a result, 77 million share equivalents
 related to mandatory convertible preferred were not included in the
 computation of diluted EPS.&amp;#xA0;Additionally, 24 million stock
 awards, 42 million stock options, and 28 million share equivalents
 related to convertible debt were not included in the computation of
 diluted EPS.&amp;#xA0;Had Alcoa generated sufficient net income in the
 first quarter of 2016, 77 million, 28 million, 10 million, and 2
 million potential shares of common stock related to mandatory
 convertible preferred stock, convertible notes, stock awards, and
 stock options, respectively, would have been included in diluted
 average shares outstanding.&lt;/p&gt;

 stock at a weighted average exercise price of $12.74 and $14.79 per

 they were anti-dilutive, as the exercise prices of the options were
 greater than the average market price of Alcoa&amp;#x2019;s common
 stock.&lt;/p&gt;

 goodwill of $117 for this transaction, none of which is deductible
 for income tax purposes. The purchase price allocation has been
 finalized.&lt;/p&gt;

 In July 2015, Alcoa completed the acquisition of RTI International
 Metals, Inc. (RTI). RTI was 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 was to expand Alcoa&amp;#x2019;s range of titanium
 offerings and add advanced technologies and materials, primarily
 related to the aerospace end market. Alcoa purchased all
 outstanding shares of RTI common stock in a stock-for-stock
 transaction valued at $870 (based on the $9.96 per share July 23,
 2015 closing price of Alcoa&amp;#x2019;s common stock). Each issued and
 outstanding share of RTI common stock prior to the completion of
 the transaction was converted into the right to receive 2.8315
 shares of Alcoa common stock. In total, Alcoa issued 87,397,414
 shares of its common stock to consummate this transaction. The
 operating results and assets and liabilities of RTI were included
 within Alcoa&amp;#x2019;s Engineered Products and Solutions segment
 since the date of acquisition. Based on the preliminary allocation
 of the purchase price, goodwill of $251 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&amp;#x2019;s best estimates, including a third-party
 valuation of the assets acquired and other studies related to
 potential environmental and contingent liabilities.&lt;/p&gt;

 In March 2016, Alcoa reached an agreement for the sale of its
 Remmele Medical business for $102 in cash, subject to post-closing
 adjustments (this transaction closed on April&amp;#xA0;29, 2016). This
 business, which was acquired by Alcoa in July 2015 in conjunction
 with the RTI acquisition, generated sales of approximately $16 in
 the first quarter of 2016. The operating results and assets and
 liabilities of the business were included in the Engineered
 Products and Solutions segment.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Also in March 2016, Alcoa&amp;#x2019;s majority-owned subsidiary, Alcoa
 of Australia Limited (AofA), which is part of Alcoa World Alumina
 and Chemicals (AWAC), reached an agreement to sell its 20% interest
 in DBP, the owner and operator of the Dampier to Bunbury Natural
 Gas Pipeline (DBNGP) for $154 (A$205) in cash. As part of the
 transaction, AofA will maintain its current access to approximately
 30% of the DBNGP transmission capacity for gas supply to its three
 alumina refineries in Western Australia.&amp;#xA0;See Note&amp;#xA0;G for
 additional information.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Additionally in March 2016, Alcoa sold certain company-owned life
 insurance contracts for $234 in cash.&amp;#xA0;No gain or loss was
 recognized on the sale of these contracts.&amp;#xA0;These contracts
 were included in Other noncurrent assets on the accompanying
 Consolidated Balance Sheet at December&amp;#xA0;31, 2015.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In the first quarter of 2015, 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.&amp;#xA0;The divestiture
 and post-closing adjustments combined resulted in a net cash
 payment of $8 and a net loss of $149 ($142 after-tax and
 noncontrolling interest), which was recorded in Restructuring and
 other charges (see Note D) on the accompanying Statement of
 Consolidated Operations.&amp;#xA0;These four divestitures are no longer
 subject to post-closing adjustments.&lt;/p&gt;

 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.&amp;#xA0;While owned by Alcoa, the operating results
 and assets and liabilities of the rolling mill were included in the
 Global Rolled Products segment.&lt;/p&gt;

 &lt;td valign="top" align="left"&gt;The fair value of the energy contract
 reflected as a liability in this table is lower by $6 compared to
 the respective amount reflected in the Level 3 tables presented
 below.&amp;#xA0;This is due to the fact that this contract is in a
 liability position for the current portion but is in an asset
 position for the noncurrent portion, and is reflected as such on
 the accompanying Consolidated Balance Sheet.&amp;#xA0;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 its entirety.&lt;/td&gt;

 &lt;b&gt;O. Proposed Separation Transaction&lt;/b&gt; &amp;#x2013; On September 28,
 2015, Alcoa announced that its Board of Directors approved a plan
 to separate into two independent, publicly-traded companies: An
 Upstream Company, the new Alcoa, that will primarily comprise the
 Alumina and Primary Metals segments; and a Value-Add Company,
 Arconic, that will principally include the Global Rolled Products,
 Engineered Products and Solutions, and Transportation and
 Construction Solutions segments. The Company currently plans that
 upon separation, which is targeted in the second half of 2016, the
 new Alcoa will also become owner of the rolling mill at the
 Warrick, IN Operations and the stake in the Ma&amp;#x2019;aden Rolling
 Company in Saudi Arabia.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt"&gt;
 The transaction is subject to a number of conditions, including,
 but not limited to, final approval by Alcoa&amp;#x2019;s Board of
 Directors, receipt of a favorable opinion of legal counsel with
 respect to the tax-free nature of the transaction for U.S. federal
 income tax purposes, and the effectiveness of a Form 10
 registration statement to be filed with the U.S. Securities and
 Exchange Commission. Upon completion of the separation, Alcoa
 shareholders will own all of the outstanding shares of both
 companies. Alcoa may, at any time and for any reason until the
 proposed transaction is complete, abandon the separation plan or
 modify or change its terms. For the first quarter of 2016, Alcoa
 recognized $18 ($17 after-tax) in Selling, general administrative,
 and other expenses on the accompanying Statement of Consolidated
 Operations for costs related to the proposed transaction.&lt;/p&gt;

 On January 1, 2016, Alcoa adopted changes issued by the Financial
 Accounting Standards Board (FASB) 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, previously, were required to be presented
 separately in an entity&#x2019;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 is no longer required. Notwithstanding
 this change, an entity is still 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. The
 adoption of these changes had no impact on the Consolidated
 Financial Statements.</p>

 On January 1, 2016, Alcoa adopted changes issued by the FASB to the
 analysis an entity must perform to determine whether it should
 consolidate certain types of legal entities.&#xA0;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.&#xA0;The adoption of these changes
 had no impact on the Consolidated Financial Statements.</p>

 On January 1, 2016, Alcoa adopted changes issued by the FASB to the
 presentation of debt issuance costs. Previously, such costs were
 required to be presented as a noncurrent asset in an entity&#x2019;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&#x2019;s balance sheet as a direct
 deduction from the carrying value of the related debt liability.
 The amortization of debt issuance costs remains unchanged. The FASB
 issued an update to these changes based on an announcement of the
 staff of the U.S. Securities and Exchange Commission. This update
 provides an exception to the FASB changes allowing debt issuance
 costs related to line-of-credit arrangements to continue to be
 presented as an asset regardless of whether there are any
 outstanding borrowings under such arrangement. This additional
 change also was adopted by Alcoa on January 1, 2016. This adoption
 is required on a retrospective basis; therefore, the December 31,
 2015 Consolidated Balance Sheet has been updated to conform to the
 March 31, 2016 presentation. As a result, $51 of debt issuance
 costs (previously reported in Other noncurrent assets) were
 reclassified to the Long-term debt, less amount due within one year
 line item on the December 31, 2015 Consolidated Balance Sheet.</p>

 In March 2016, the FASB issued changes to employee share-based
 payment accounting.&#xA0;Currently, an entity must determine for
 each share-based payment award whether the difference between the
 deduction for tax purposes and the compensation cost recognized for
 financial reporting purposes results in either an excess tax
 benefit or a tax deficiency.&#xA0;Excess tax benefits are
 recognized in additional paid-in capital; tax deficiencies are
 recognized either as an offset to accumulated excess tax benefits,
 if any, or in the income statement. Excess tax benefits are not
 recognized until the deduction reduces taxes payable. The changes
 require all excess tax benefits and tax deficiencies related to
 share-based payment awards to be recognized as income tax expense
 or benefit in the income statement. The tax effects of exercised or
 vested awards should be treated as discrete items in the reporting
 period in which they occur. An entity also should recognize excess
 tax benefits regardless of whether the benefit reduces taxes
 payable in the current period. Additionally, the presentation of
 excess tax benefits related to share-based payment awards in the
 statement of cash flows is changed. Currently, excess tax benefits
 must be separated from other income tax cash flows and classified
 as a financing activity. The changes require excess tax benefits to
 be classified along with other income tax cash flows as an
 operating activity. Also, the changes require cash paid by an
 employer when directly withholding shares for tax-withholding
 purposes to be classified as a financing activity. Currently, there
 is no specific guidance on the classification in the statement of
 cash flows of cash paid by an employer to the tax authorities when
 directly withholding shares for tax-withholding purposes.
 Additionally, for a share-based award to qualify for equity
 classification it cannot partially settle in cash in excess of the
 employer&#x2019;s minimum statutory withholding requirements. The
 changes permit equity classification of share-based awards for
 withholdings up to the maximum statutory tax rates in applicable
 jurisdictions. These changes become effective for Alcoa on January
 1, 2017. Management is currently evaluating the potential impact of
 these changes on the Consolidated Financial Statements.</p>

 In March 2016, the FASB issued changes eliminating the requirement
 for an investor to adjust an equity method investment, results of
 operations, and retained earnings retroactively on a step-by-step
 basis as if the equity method had been in effect during all
 previous periods that the investment had been held as a result of
 an increase in the level of ownership interest or degree of
 influence.&#xA0;Additionally, an entity that has an
 available-for-sale equity security that becomes qualified for the
 equity method of accounting must recognize through earnings the
 unrealized holding gain or loss in accumulated other comprehensive
 income at the date the investment becomes qualified for use of the
 equity method.&#xA0;These changes become effective for Alcoa on
 January 1, 2017.&#xA0;Management is currently evaluating the
 potential impact of these changes on the Consolidated Financial
 Statements.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 In March 2016, the FASB issued changes to derivative instruments
 designated as hedging instruments.&#xA0;These changes clarify that
 a change in the counterparty to a derivative instrument that has
 been designated as a hedging instrument does not, in and of itself,
 require dedesignation of that hedging relationship provided that
 all other hedge accounting criteria continue to be met. These
 changes become effective for Alcoa on January 1,
 2017.&#xA0;Management does not expect these changes to have a
 material impact on the Consolidated Financial Statements.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 In February 2016, the FASB issued changes to the accounting and
 presentation of leases.&#xA0;These changes require lessees to
 recognize a right of use asset and lease liability on the balance
 sheet for all leases with terms longer than 12 months.&#xA0;For
 leases with a term of 12 months or less, a lessee is permitted to
 make an accounting policy election by class of underlying asset not
 to recognize a right of use asset and lease
 liability.&#xA0;Additionally, when measuring assets and liabilities
 arising from a lease, optional payments should be included only if
 the lessee is reasonably certain to exercise an option to extend
 the lease, exercise a purchase option, or not exercise an option to
 terminate the lease.&#xA0;These changes become effective for Alcoa
 on January 1, 2019.&#xA0;Management is currently evaluating the
 potential impact of these changes on the Consolidated Financial
 Statements.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 In January 2016, the FASB issued changes to equity
 investments.&#xA0;These changes require equity investments (except
 those accounted for under the equity method of accounting or those
 that result in consolidation of the investee) to be measured at
 fair value with changes in fair value recognized in net
 income.&#xA0;However, an entity may choose to measure equity
 investments that do not have readily determinable fair values at
 cost minus impairment, if any, plus or minus changes resulting from
 observable price changes in orderly transactions for the identical
 or similar investment of the same issuer.&#xA0;Additionally, the
 impairment assessment of equity investments without readily
 determinable fair values has been simplified by requiring a
 qualitative assessment to identify impairment. These changes become
 effective for Alcoa on January 1, 2018.&#xA0;Management is
 currently evaluating the potential impact of these changes on the
 Consolidated Financial Statements.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 In July 2015, the FASB issued changes to the subsequent measurement
 of inventory.&#xA0;Currently, an entity is required to measure its
 inventory at the lower of cost or market, whereby market can be
 replacement cost, net realizable value, or net realizable value
 less an approximately normal profit margin.&#xA0;The changes
 require that inventory be measured at the lower of cost and net
 realizable value, thereby eliminating the use of the other two
 market methodologies.&#xA0;Net realizable value is defined as the
 estimated selling prices in the ordinary course of business less
 reasonably predictable costs of completion, disposal, and
 transportation.&#xA0;These changes do not apply to inventories
 measured using LIFO (last-in, first-out) or the retail inventory
 method.&#xA0;Currently, Alcoa applies the net realizable value
 market option to measure non-LIFO inventories at the lower of cost
 or market.&#xA0;These changes become effective for Alcoa on January
 1, 2017.&#xA0;Management has determined that the adoption of these
 changes will not have an impact on the Consolidated Financial
 Statements.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%">
 In May 2014, the FASB issued changes to the recognition of revenue
 from contracts with customers.&#xA0;These changes created a
 comprehensive framework for all entities in all industries to apply
 in the determination of when to recognize revenue, and, therefore,
 supersede virtually all existing revenue recognition requirements
 and guidance.&#xA0;This framework is expected to result in less
 complex guidance in application while providing a consistent and
 comparable methodology for revenue recognition.&#xA0;The core
 principle of the guidance is that an entity should recognize
 revenue to depict the transfer of promised goods or
 services.&#xA0;To achieve this principle, an entity should apply
 the following steps: (i) identify the contract(s) with a customer,
 (ii) identify the performance obligations in the contract(s), (iii)
 determine the transaction price, (iv) allocate the transaction
 price to the performance obligations in the contract(s), and (v)
 recognize revenue when, or as, the entity satisfies a performance
 obligation.&#xA0;In August 2015, the FASB deferred the effective
 date by one year, making these changes effective for Alcoa on
 January 1, 2018.&#xA0;In March 2016, the FASB issued amendments to
 clarify the implementation guidance on principal versus agent
 considerations.&#xA0;Management is currently evaluating the
 potential impact of these changes on the Consolidated Financial
 Statements.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 In August 2014, the FASB issued changes to the disclosure of
 uncertainties about an entity&#x2019;s ability to continue as a
 going concern. Under GAAP, continuation of a reporting entity as a
 going concern is presumed as the basis for preparing financial
 statements unless and until the entity&#x2019;s liquidation becomes
 imminent. Even if an entity&#x2019;s liquidation is not imminent,
 there may be conditions or events that raise substantial doubt
 about the entity&#x2019;s ability to continue as a going concern.
 Because there is no guidance in GAAP about management&#x2019;s
 responsibility to evaluate whether there is substantial doubt about
 an entity&#x2019;s ability to continue as a going concern or to
 provide related note disclosures, there is diversity in practice
 whether, when, and how an entity discloses the relevant conditions
 and events in its financial statements. As a result, these changes
 require an entity&#x2019;s management to evaluate whether there are
 conditions or events, considered in the aggregate, that raise
 substantial doubt about the entity&#x2019;s ability to continue as a
 going concern within one year after the date that financial
 statements are issued. Substantial doubt is defined as an
 indication that it is probable that an entity will be unable to
 meet its obligations as they become due within one year after the
 date that financial statements are issued. If management has
 concluded that substantial doubt exists, then the following
 disclosures should be made in the financial statements:
 (i)&#xA0;principal conditions or events that raised the substantial
 doubt, (ii)&#xA0;management&#x2019;s evaluation of the significance
 of those conditions or events in relation to the entity&#x2019;s
 ability to meet its obligations, (iii)&#xA0;management&#x2019;s
 plans that alleviated the initial substantial doubt or, if
 substantial doubt was not alleviated, management&#x2019;s plans that
 are intended to at least mitigate the conditions or events that
 raise substantial doubt, and (iv)&#xA0;if the latter in
 (iii)&#xA0;is disclosed, an explicit statement that there is
 substantial doubt about the entity&#x2019;s ability to continue as a
 going concern. These changes become effective for Alcoa for the
 2016 annual financial statements. Management has determined that
 the adoption of these changes will not have an impact on the
 Consolidated Financial Statements. Subsequent to adoption, this
 guidance will need to be applied by management at the end of each
 annual period and interim period therein to determine what, if any,
 impact there will be on the Consolidated Financial Statements in a
 given reporting period.</p>

 <b>D. Restructuring and Other Charges</b>&#xA0;&#x2013; In the first quarter
 of 2016, Alcoa recorded Restructuring and other charges of $93 ($61
 after-tax and noncontrolling interest), which were comprised of the
 following components: $60 ($39 after-tax) related to the 2015
 announced permanent closure of the Warrick smelter; $19 ($14
 after-tax and noncontrolling interest) for layoff costs, including
 the separation of approximately 560 employees (500 in the
 Engineered Products and Solutions segment, 30 in the Primary Metals
 segment, and 30 in the Global Rolled Products segment); $18 ($11
 after-tax and noncontrolling interest) related to the curtailments
 of the Point Comfort refinery and Wenatchee smelter; and $4 ($3
 after-tax and noncontrolling interest) for the reversal of a number
 of small layoff reserves related to prior periods and other
 miscellaneous items.</p>

 In 2016, costs related to the closure and curtailment actions
 included $70 for accelerated depreciation as the Warrick facility
 continued to operate through March 2016, $27 in other exit costs
 primarily for contract terminations, and $19 for the reversal of
 previously accrued severance costs that will not be
 incurred.&#xA0;Additionally in the first quarter of 2016,
 inventories were written down to their net realizable value,
 resulting in a charge of $3 ($2 after-tax), which was recorded in
 Cost of goods sold on the accompanying Statement of Consolidated
 Operations.</p>

 divestiture of a rolling mill in Russia and post-closing
 adjustments associated with three December 2014 divestitures; $16
 ($11 after-tax) for the separation of approximately 680 employees
 (Primary Metals segment) and supplier contract-related costs
 associated with the decision to temporarily curtail the remaining
 capacity (74,000 metric-tons-per-year) at the S&#xE3;o Lu&#xED;s
 smelter in Brazil; $13 ($8 after-tax and noncontrolling interest)
 for layoff costs, including the separation of approximately 210
 employees (80 in the Engineered Products and Solutions segment, 40
 in the Transportation and Construction Solutions segment, 30 in the
 Global Rolled Products segment, and 60 in Corporate); a net charge
 of $6 ($3 after-tax and noncontrolling interest) for other

 <b>E. Acquisitions and Divestitures</b> &#x2013; In March 2015,
 Alcoa completed the acquisition of an aerospace structural castings
 company, TITAL, for $205 (&#x20AC;189) in cash. Alcoa recognized
 goodwill of $117 for this transaction, none of which is deductible
 for income tax purposes. The purchase price allocation has been
 finalized.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 In July 2015, Alcoa completed the acquisition of RTI International
 Metals, Inc. (RTI). RTI was 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 was to expand Alcoa&#x2019;s range of titanium
 offerings and add advanced technologies and materials, primarily
 related to the aerospace end market. Alcoa purchased all
 outstanding shares of RTI common stock in a stock-for-stock
 transaction valued at $870 (based on the $9.96 per share July 23,
 2015 closing price of Alcoa&#x2019;s common stock). Each issued and
 outstanding share of RTI common stock prior to the completion of
 the transaction was converted into the right to receive 2.8315
 shares of Alcoa common stock. In total, Alcoa issued 87,397,414
 shares of its common stock to consummate this transaction. The
 operating results and assets and liabilities of RTI were included
 within Alcoa&#x2019;s Engineered Products and Solutions segment
 since the date of acquisition. Based on the preliminary allocation
 of the purchase price, goodwill of $251 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&#x2019;s best estimates, including a third-party
 valuation of the assets acquired and other studies related to
 potential environmental and contingent liabilities.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 In March 2016, Alcoa reached an agreement for the sale of its
 Remmele Medical business for $102 in cash, subject to post-closing
 adjustments (this transaction closed on April&#xA0;29, 2016). This
 business, which was acquired by Alcoa in July 2015 in conjunction
 with the RTI acquisition, generated sales of approximately $16 in
 the first quarter of 2016. The operating results and assets and
 liabilities of the business were included in the Engineered
 Products and Solutions segment.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 Also in March 2016, Alcoa&#x2019;s majority-owned subsidiary, Alcoa
 of Australia Limited (AofA), which is part of Alcoa World Alumina
 and Chemicals (AWAC), reached an agreement to sell its 20% interest
 in DBP, the owner and operator of the Dampier to Bunbury Natural
 Gas Pipeline (DBNGP) for $154 (A$205) in cash. As part of the
 transaction, AofA will maintain its current access to approximately
 30% of the DBNGP transmission capacity for gas supply to its three
 alumina refineries in Western Australia.&#xA0;See Note&#xA0;G for
 additional information.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 Additionally in March 2016, Alcoa sold certain company-owned life
 insurance contracts for $234 in cash.&#xA0;No gain or loss was
 recognized on the sale of these contracts.&#xA0;These contracts
 were included in Other noncurrent assets on the accompanying
 Consolidated Balance Sheet at December&#xA0;31, 2015.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 In the first quarter of 2015, 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.&#xA0;The divestiture
 and post-closing adjustments combined resulted in a net cash
 payment of $8 and a net loss of $149 ($142 after-tax and
 noncontrolling interest), which was recorded in Restructuring and
 other charges (see Note D) on the accompanying Statement of
 Consolidated Operations.&#xA0;These four divestitures are no longer
 subject to post-closing adjustments.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 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.&#xA0;While owned by Alcoa, the operating results
 and assets and liabilities of the rolling mill were included in the
 Global Rolled Products segment.</p>

 On June 5, 2015, Alcoa World Alumina LLC (&#x201C;AWA&#x201D;) and
 St. Croix Alumina, L.L.C. (&#x201C;SCA&#x201D;) filed a complaint in
 Delaware Chancery Court for a declaratory judgment and injunctive
 relief to resolve a dispute between Alcoa and Glencore Ltd.
 (&#x201C;Glencore&#x201D;) with respect to claimed obligations under
 a 1995 asset purchase agreement between Alcoa and
 Glencore.&#xA0;The dispute arose from Glencore&#x2019;s demand that
 Alcoa indemnify it for liabilities it may have to pay to Lockheed
 Martin (&#x201C;Lockheed&#x201D;) related to the St. Croix alumina
 refinery.&#xA0;Lockheed had earlier filed suit against Glencore in
 federal court in New York seeking indemnity for liabilities it had
 incurred and would incur to the U.S. Virgin Islands to remediate
 certain properties at the refinery property and claimed that
 Glencore was required by an earlier, 1989 purchase agreement to
 indemnify it.&#xA0;Glencore had demanded that Alcoa indemnify and
 defend it in the Lockheed case and threatened to claim against
 Alcoa in the New York action despite exclusive jurisdiction for
 resolution of disputes under the 1995 purchase agreement being in
 Delaware.&#xA0;After Glencore conceded that it was not seeking to
 add Alcoa to the New York action, AWA and SCA dismissed their
 complaint in the Chancery Court case and on August 6, 2015 filed a
 complaint for declaratory judgment in Delaware Superior
 Court.&#xA0;AWA and SCA filed a motion for judgment on the
 pleadings on September 16, 2015. Glencore answered AWA&#x2019;s and
 SCA&#x2019;s complaint and asserted counterclaims on August 27,
 2015, and on October 2, 2015 filed its own motion for judgment on
 the pleadings.&#xA0;Argument on the parties&#x2019; motions was held
 by the court on December 7, 2015, and by order dated February 8,
 2016, the court granted Alcoa&#x2019;s motion and denied
 Glencore&#x2019;s motion, resulting in Alcoa not being liable to
 indemnify Glencore for the Lockheed action. The decision also
 leaves for pretrial discovery and possible summary judgment or
 trial Glencore&#x2019;s claims for costs and fees it incurred in
 defending and settling an earlier Superfund action brought against
 Glencore by the Government of the Virgin Islands. On February 17,
 2016, Glencore filed notice of its application for interlocutory
 appeal of the February&#xA0;8 ruling. AWA and SCA filed an
 opposition to that application on February 29, 2016. On March 10,
 2016, the court denied Glencore&#x2019;s motion for interlocutory
 appeal and on the same day entered judgment on claims other than
 Glencore&#x2019;s claims for costs and fees it incurred in defending
 and settling the earlier Superfund action brought against Glencore
 by the Government of the Virgin Islands. On March 29, 2016,
 Glencore filed a withdrawal of its notice of interlocutory appeal
 and also noted its intent to appeal the court&#x2019;s March 10,
 2016 judgment. At this time, the Company is unable to reasonably
 predict an outcome for this matter.</p>

 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 (&#x201C;204/1999&#x201D;). 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 &#x201C;state aid.&#x201D; 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).&#xA0;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 (&#x20AC;85), including interest.&#xA0;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 (&#x201C;44/2012&#x201D;) came into effect, changing the
 method to calculate the drawback. On February 21, 2013, Alcoa
 received a revised request letter from CCSE demanding Alcoa&#x2019;s
 subsidiary, Alcoa Trasformazioni S.r.l., make a payment in the
 amount of $97 (&#x20AC;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 (&#x20AC;76). Alcoa rejected that demand and
 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
 that date, the Administrative Court listened to Alcoa&#x2019;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&#x2019;s
 September 2, 2014 decision; however, a date for the hearing has not
 been scheduled. Management recorded a partial reserve for this
 matter of $37 (&#x20AC;34) during the quarter ended December 31,
 2015 (see Note N in the Company&#x2019;s Annual Report on Form 10-K
 for the year ended December 31, 2015). At this time, the Company is
 unable to reasonably predict an outcome for this matter.</p>

 <b>Massena West, NY&#x2014;</b>Alcoa has an ongoing remediation
 project related to the Grasse River, which is adjacent to
 Alcoa&#x2019;s Massena plant site.&#xA0;Many years ago, it was
 determined that sediments and fish in the river contain varying
 levels of polychlorinated biphenyls (PCBs).&#xA0;The project, which
 was selected by the U.S. Environmental Protection Agency (EPA) in a
 Record of Decision (ROD) issued in April 2013, is aimed at capping
 PCB contaminated sediments with concentration in excess of one part
 per million in the main channel of the river and dredging PCB
 contaminated sediments in the near-shore areas where total PCBs
 exceed one part per million.&#xA0;At March 31, 2016 and December
 31, 2015, the reserve balance associated with this matter was $233
 and $234, respectively.&#xA0;Alcoa is in the planning and design
 phase, which is expected to be completed in 2017.&#xA0;Subsequently
 in 2017, the actual remediation fieldwork is expected to commence
 and take approximately four years.&#xA0;The majority of the project
 funding is expected to be spent between 2017 and 2021.</p>

 <b>Sherwin, TX&#x2014;</b>In connection with the sale of the Sherwin
 alumina refinery, which was required to be divested as part of the
 Reynolds merger in 2000, Alcoa agreed to retain responsibility for
 the remediation of the then existing environmental conditions, as
 well as a pro rata share of the final closure of the active bauxite
 residue waste disposal areas (known as the Copano facility).
 Alcoa&#x2019;s share of the closure costs is proportional to the
 total period of operation of the active waste disposal areas. At
 March 31, 2016 and December 31, 2015, the reserve balance
 associated with Sherwin was $30. Approximately half of the project
 funding is expected to be spent through 2019. The remainder is not
 expected to be spent in the foreseeable future as it is dependent
 upon the operating life of the active waste disposal areas.</p>

 <b>East St. Louis, IL&#x2014;</b>Alcoa has an ongoing remediation
 project related to an area used for the disposal of bauxite residue
 from former alumina refining operations. The project, which was
 selected by the EPA in a ROD issued in July 2012, is aimed at
 implementing a soil cover over the affected area. On November 1,
 2013, the U.S. Department of Justice lodged a consent decree on
 behalf of the EPA for Alcoa to conduct the work outlined in the
 ROD. This consent decree was entered as final in February 2014 by
 the U.S. Department of Justice. As a result, Alcoa began
 construction in March 2014; this project is expected to be
 completed by the end of June 2016 (Alcoa has a second project in
 East St. Louis that is separate from the matter presented herein on
 which Alcoa is expecting an EPA decision in 2016 &#x2013; any
 resulting liability is not expected to be material). At March 31,
 2016 and December 31, 2015, the reserve balance associated with
 this matter was $7 and $8, respectively.</p>

 <b>Fusina and Portovesme, Italy&#x2014;</b>In 1996, Alcoa acquired
 the Fusina smelter and rolling operations and the Portovesme
 smelter, both of which are owned by Alcoa&#x2019;s subsidiary Alcoa
 Trasformazioni S.r.l. (&#x201C;Trasformazioni&#x201D;), from Alumix,
 an entity owned by the Italian Government. At the time of the
 acquisition, Alumix indemnified Alcoa for pre-existing
 environmental contamination at the sites. In 2004, the Italian
 Ministry of Environment and Protection of Land and Sea (MOE) issued
 orders to Trasformazioni and Alumix for the development of a
 clean-up plan related to soil contamination in excess of allowable
 limits under legislative decree and to institute emergency actions
 and pay natural resource damages. Trasformazioni appealed the
 orders and filed suit against Alumix, among others, seeking
 indemnification for these liabilities under the provisions of the
 acquisition agreement. In 2009, Ligestra S.r.l.
 (&#x201C;Ligestra&#x201D;), Alumix&#x2019;s successor, and
 Trasformazioni agreed to a stay of the court proceedings while
 investigations were conducted and negotiations advanced towards a
 possible settlement.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 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).&#xA0;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.&#xA0;The agreement was contingent
 upon final acceptance of the remediation project by the
 MOE.&#xA0;As a result of entering into this agreement, Alcoa
 increased the reserve by $12 in 2009 for Fusina.&#xA0;Based on
 comments received from the MOE and local and regional environmental

 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. The agreement
 includes both a soil and groundwater remediation project estimated
 to cost $33 (&#x20AC;24) and requires payments of $25 (&#x20AC;18) to
 the MOE for emergency action and natural resource damages. The
 remediation projects are slated to begin as soon as Alcoa receives
 final approval from the Ministry of Infrastructure. Based on the
 final agreement with Ligestra, Alcoa&#x2019;s share of all costs and
 payments is $17 (&#x20AC;12), of which $9 (&#x20AC;6) related to the
 damages will be paid annually over a 10-year period, which began in
 April 2014, and was previously fully reserved.</p>

 Separately, in 2009, due to additional information derived from the
 site investigations conducted at Portovesme, Alcoa increased the
 reserve by $3.&#xA0;In November 2011, Trasformazioni and Ligestra
 reached an agreement for settlement of the liabilities related to
 Portovesme, similar to the one for Fusina.&#xA0;A proposed soil
 remediation project for Portovesme was formally presented to the
 MOE in June 2012.&#xA0;Neither the agreement with Ligestra nor the
 proposal to the MOE resulted in a change to the reserve for
 Portovesme.&#xA0;In November 2013, the MOE rejected the proposed
 soil remediation project and requested a revised project be
 submitted.&#xA0;In May 2014, Trasformazioni and Ligestra submitted
 a revised soil remediation project that addressed certain
 stakeholders&#x2019; 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.</p>

 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.&#xA0;Trasformazioni
 and Ligestra submitted the further revised soil remediation project
 in February 2015.&#xA0;As a result, Alcoa increased the reserve by
 $7 in March 2015 to reflect the increase in the estimated costs of
 the project.&#xA0;In October 2015, Alcoa received a final
 ministerial decree approving the February 2015 revised soil
 remediation project.&#xA0;Work on the soil remediation project will
 commence in 2016 and is expected to be completed in
 2019.&#xA0;Alcoa and Ligestra are now working on a final
 groundwater remediation project, which will be submitted to the MOE
 for review during 2016.&#xA0;The ultimate outcome of this matter

 <b>Baie Comeau, Quebec, Canada&#x2014;</b>In August 2012, Alcoa
 presented an analysis of remediation alternatives to the Quebec
 Ministry of Sustainable Development, Environment, Wildlife and
 Parks (MDDEP), in response to a previous request, related to known
 PCBs and polycyclic aromatic hydrocarbons (PAHs) contained in
 sediments of the Anse du Moulin bay.&#xA0;As such, Alcoa increased
 the reserve for Baie Comeau by $25 in 2012 to reflect the estimated
 cost of Alcoa&#x2019;s recommended alternative, consisting of both
 dredging and capping of the contaminated sediments. In July 2013,
 Alcoa submitted the Environmental Impact Assessment for the project
 to the MDDEP. The MDDEP notified Alcoa that the project as it was
 submitted was approved and a final ministerial decree was issued in
 July 2015. As a result, no further adjustment to the reserve was
 required in 2015. The decree provides final approval for the
 project and allows Alcoa to start work on the final project design,
 which is expected to be completed in 2016 with construction on the
 project expected to begin in 2017. Completion of the final project
 design and bidding of the project may result in additional
 liability in a future period.</p>

 <b>Mosj&#xF8;en, Norway&#x2014;</b>In September 2012, Alcoa
 presented an analysis of remediation alternatives to the Norwegian
 Environmental Agency (NEA) (formerly the Norwegian Climate and
 Pollution Agency, or &#x201C;Klif&#x201D;), in response to a previous
 request, related to known PAHs in the sediments located in the
 harbor and extending out into the fjord. As such, Alcoa increased
 the reserve for Mosj&#xF8;en by $20 in 2012 to reflect the
 estimated cost of the baseline alternative for dredging of the
 contaminated sediments. A proposed project reflecting this
 alternative was formally presented to the NEA in June 2014, and was
 resubmitted in late 2014 to reflect changes by the NEA. The revised
 proposal did not result in a change to the reserve for
 Mosj&#xF8;en.</p>

 In April 2015, the NEA notified Alcoa that the revised project was
 approved and required submission of the final project design before
 issuing a final order.&#xA0;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.&#xA0;As a result, Alcoa increased the reserve for
 Mosj&#xF8;en by $11 in June 2015 to reflect the estimated cost of
 the wharf stabilization. Also in June 2015, the NEA issued a final
 order approving the project as well as the final project design. In
 September 2015, Alcoa increased the reserve by $1 to reflect the
 potential need (based on prior experience with similar projects) to
 perform additional dredging if the results of sampling, which is
 required by the order, don&#x2019;t achieve the required cleanup
 levels. Project construction will commence in 2016 and is expected

 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&#x2019;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&#x2019;s

 Additionally, following a corporate income tax audit of the same
 Spanish tax group for the 2006 through 2009 tax years,
 Spain&#x2019;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

 The combined assessments (remeasured for a tax rate change enacted
 in November 2014) total $273 (&#x20AC;241), including interest. The
 Company believes it has meritorious arguments to support its tax
 position and intends to vigorously litigate the assessments through
 Spain&#x2019;s court system.&#xA0;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

 In March 2013, Alcoa&#x2019;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.&#xA0;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 S&#xE3;o Lu&#xED;s 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.&#xA0;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.&#xA0;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.&#xA0;Separately from
 AWAB&#x2019;s administrative appeal, in June 2015, new tax law was
 enacted repealing the provisions in the tax code that were the
 basis for the RFB assessing a 50% penalty in this matter. As such,
 the estimated range of reasonably possible loss is $0 to $29
 (R$103), whereby the maximum end of the range represents the
 portion of the disallowed credits applicable to the export sales
 and excludes the 50% penalty. Additionally, the estimated range of
 disallowed credits related to AWAB&#x2019;s fixed assets is $0 to
 $32 (R$117), which would increase the net carrying value of
 AWAB&#x2019;s fixed assets if ultimately disallowed. It is
 management&#x2019;s opinion that the allegations have no basis;
 however, at this time, management is unable to reasonably predict
 an outcome for this matter.</p>

 Between 2000 and 2002, Alcoa Alum&#xED;nio (Alum&#xED;nio) sold
 approximately 2,000 metric tons of metal per month from its
 Po&#xE7;os de Caldas facility, located in the State of Minas Gerais
 (the &#x201C;State&#x201D;), to Alfio, a customer also located in the
 State.&#xA0;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, Alum&#xED;nio received an assessment
 from State auditors on the theory that Alum&#xED;nio should be
 jointly and severally liable with Alfio for the unpaid VAT. In June
 2003, the administrative tribunal found Alum&#xED;nio liable, and
 Alum&#xED;nio filed a judicial case in the State in February 2004
 contesting the finding.&#xA0;In May 2005, the Court of First
 Instance found Alum&#xED;nio solely liable, and a panel of a State
 appeals court confirmed this finding in April
 2006.&#xA0;Alum&#xED;nio filed a special appeal to the Superior
 Tribunal of Justice (STJ) in Brasilia (the federal capital of
 Brazil) later in 2006.&#xA0;In 2011, the STJ (through one of its
 judges) reversed the judgment of the lower courts, finding that
 Alum&#xED;nio should neither be solely nor jointly and severally
 liable with Alfio for the VAT, which ruling was then appealed by
 the State.&#xA0;In August 2012, the STJ agreed to have the case
 reheard before a five-judge panel.&#xA0;A decision from this panel
 is pending, but additional appeals are likely.&#xA0;At March 31,

 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.&#xA0;The joint venture is owned
 74.9% by the Saudi Arabian Mining Company (known as
 &#x201C;Ma&#x2019;aden&#x201D;) 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.&#xA0;Alcoa accounts
 for its investment in the joint venture under the equity
 method.&#xA0;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&#x2019;s partners&#x2019; ownership interests.
 Originally, it was estimated that Alcoa&#x2019;s total equity
 investment in the joint venture would be approximately $1,100, of
 which Alcoa has contributed $982, including $1 in the 2016 first
 quarter. Based on changes to both the project&#x2019;s capital
 investment and equity and debt structure from the initial plans,
 the estimated $1,100 equity contribution may be reduced. As of
 March 31, 2016 and December 31, 2015, the carrying value of
 Alcoa&#x2019;s investment in this project was $906 and $928,

 In 2004, AofA 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
 AofA&#x2019;s refineries in Western Australia. AofA 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&#x2019;s capacity is planned at this time. In late 2011,
 the consortium initiated a three-year equity call plan to improve
 its capitalization structure. The plan required AofA 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 AofA to contribute
 $30 (A$36) through mid 2016, of which $20 (A$27) was made through

 In the first quarter of 2016, 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 available to Alcoa common
 shareholders.&#xA0;As a result, 77 million share equivalents
 related to mandatory convertible preferred were not included in the
 computation of diluted EPS.&#xA0;Additionally, 24 million stock
 awards, 42 million stock options, and 28 million share equivalents
 related to convertible debt were not included in the computation of
 diluted EPS.&#xA0;Had Alcoa generated sufficient net income in the
 first quarter of 2016, 77 million, 28 million, 10 million, and 2
 million potential shares of common stock related to mandatory
 convertible preferred stock, convertible notes, stock awards, and
 stock options, respectively, would have been included in diluted
 average shares outstanding.</p>

 <b>L. Receivables</b> &#x2013; Alcoa has an arrangement with three
 financial institutions to sell certain customer receivables without
 recourse on a revolving basis. The sale of such receivables is
 completed through the use of a bankruptcy remote special purpose
 entity, which is a consolidated subsidiary of Alcoa. This
 arrangement provides for minimum funding of $200 up to a maximum of
 $500 for receivables sold. On March 30, 2012, Alcoa initially sold
 $304 of customer receivables in exchange for $50 in cash and $254
 of deferred purchase price under this arrangement. Alcoa has
 received additional net cash funding of $300 for receivables sold
 ($1,358 in draws and $1,058 in repayments) since the
 program&#x2019;s inception. Draws and repayments in the 2016 first
 quarter were $100 and $0, respectively.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 As of March 31, 2016 and December 31, 2015, the deferred purchase
 price receivable was $210 and $249, respectively, which was
 included in Other receivables on the accompanying Consolidated
 Balance Sheet.&#xA0;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.&#xA0;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.&#xA0;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.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 The gross amount of receivables sold and total cash collected under
 this program since its inception was $26,055 and $25,495,
 respectively.&#xA0;Alcoa services the customer receivables for the
 financial institutions at market rates; therefore, no servicing
 asset or liability was recorded.</p>

 In conjunction with the annual measurement of the funded status of
 Alcoa&#x2019;s pension and other postretirement benefit plans at
 December 31, 2015, management elected to change the manner in which
 the interest cost component of net periodic benefit cost is
 determined in 2016 and beyond. Previously, the interest cost
 component was determined by multiplying the single equivalent rate
 and the aggregate discounted cash flows of the plans&#x2019;
 projected benefit obligations. Under the new methodology, the
 interest cost component is determined by aggregating the product of
 the discounted cash flows of the plans&#x2019; projected benefit
 obligations for each year and an individual spot rate (referred to
 as the &#x201C;spot rate&#x201D; approach). This change resulted in a
 lower interest cost component of net periodic benefit cost for the
 pension plans and other postretirement benefit plans of $24 and $4,
 respectively, in the first quarter of 2016.</p>

 <b><u>Fair Value</u></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 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&#x2019;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</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt">
 unadjusted quoted prices in active markets for identical assets or
 liabilities (Level 1) and the lowest priority to unobservable
 inputs (Level 3).&#xA0;The three levels of the fair value hierarchy
 are described below:</p>

 <b><u>Derivatives</u></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 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&#x2019;s exposure to the risks of changing commodity prices,
 interest rates, and foreign currency exchange rates.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 Alcoa&#x2019;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&#x2019;s Board of Directors on the
 scope of its activities.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 The aluminum, energy, interest rate, and foreign exchange contracts
 are held for purposes other than trading.&#xA0;They are used
 primarily to mitigate uncertainty and volatility, and to cover
 underlying exposures.&#xA0;Alcoa is not involved in trading
 activities for energy, weather derivatives, or other nonexchange
 commodity trading activities.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 A number of Alcoa&#x2019;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&#x2019;s Consolidated Financial Statements for all
 periods.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 For the aluminum contracts classified as Level 1, the total fair
 value of derivatives recorded as assets and liabilities was $4 and
 $35 and $8 and $58 at March 31, 2016 and December 31, 2015,
 respectively.&#xA0;These contracts were entered into to either
 hedge forecasted sales or purchases of aluminum in order to manage
 the associated aluminum price risk.&#xA0;Certain of these contracts
 are designated as hedging instruments, either fair value or cash
 flow, and the remaining are not designated as such.&#xA0;Combined,
 Alcoa recognized a net gain of $2 and $26 in the first quarter of
 2016 and 2015, respectively, in Sales on the accompanying Statement
 of Consolidated Operations related to these aluminum contracts.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 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.&#xA0;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.&#xA0;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.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 The following section describes the valuation methodologies used by
 Alcoa to measure its Level 3 derivative instruments at fair
 value.&#xA0;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.&#xA0;Alcoa uses a discounted cash flow model to fair value
 all Level 3 derivative instruments.&#xA0;Where appropriate, the
 description below includes the key inputs to those models and any
 significant assumptions.&#xA0;These valuation models are reviewed
 and tested at least on an annual basis.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 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).&#xA0;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.&#xA0;Additionally, for periods beyond the term of
 quoted market prices for energy, management has developed a forward
 curve based on independent consultant market research.&#xA0;Where
 appropriate, valuations are adjusted for various factors such as
 liquidity, bid/offer spreads, and credit considerations.&#xA0;Such
 adjustments are generally based on available market evidence (Level
 2). In the absence of such evidence, management&#x2019;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).</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 Alcoa has embedded derivatives in two power contracts that index
 the price of power to the LME price of aluminum.&#xA0;Additionally,
 Alcoa has embedded derivatives in 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.&#xA0;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 Midwest premium curve.&#xA0;Significant increases or
 decreases in the actual LME price beyond 10 years and/or the
 Midwest premium beyond 5 years would result in a higher or lower
 fair value measurement.&#xA0;An increase in actual LME price and/or
 the Midwest premium over the inputs used in the valuation models
 will result in a higher cost of power and a corresponding decrease
 to the derivative asset or increase to the derivative
 liability.&#xA0;The embedded derivatives have been designated as
 cash flow hedges of forward sales of aluminum.&#xA0;Unrealized
 gains and losses were included in Other comprehensive loss on the
 accompanying Consolidated Balance Sheet while realized gains and
 losses were included in Sales on the accompanying Statement of
 Consolidated Operations.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 Also, Alcoa has a power contract separate from above that contains
 an LME-linked embedded derivative.&#xA0;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.&#xA0;Significant increases or decreases
 in the LME price would result in a higher or lower fair value
 measurement.&#xA0;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.&#xA0;This
 embedded derivative did not qualify for hedge accounting
 treatment.&#xA0;Unrealized gains and losses from the embedded
 derivative were included in Other expenses (income), net on the
 accompanying Statement of Consolidated Operations while realized
 gains and losses were included in Cost of goods sold on the
 accompanying Statement of Consolidated Operations as electricity
 purchases were made under the contract.&#xA0;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.&#xA0;This deferred credit is recognized in Other expenses
 (income), net on the accompanying Statement of Consolidated
 Operations as power is received over the life of the contract.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 Additionally, Alcoa has a natural gas supply contract, which has an
 LME-linked ceiling.&#xA0;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.&#xA0;Any change
 in the interrelationship would result in a higher or lower fair
 value measurement.&#xA0;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.&#xA0;An
 increase in oil prices with no similar increase in the LME price
 would limit the increase of the price paid for natural
 gas.&#xA0;This embedded derivative did not qualify for hedge
 accounting treatment.&#xA0;Unrealized gains and losses from the
 embedded derivative were included in Other expenses (income), net
 on the accompanying Statement of Consolidated Operations while
 realized gains and losses were included in Cost of goods sold on
 the accompanying Statement of Consolidated Operations as gas
 purchases were made under the contract.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 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.&#xA0;Management uses market prices, historical
 relationships, and forecast services to determine fair
 value.&#xA0;Significant increases or decreases in any of these
 inputs would result in a lower or higher fair value
 measurement.&#xA0;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.&#xA0;This
 embedded derivative did not qualify for hedge accounting
 treatment.&#xA0;Unrealized gains and losses were included in Other
 expenses (income), net on the accompanying Statement of
 Consolidated Operations while realized gains and losses were
 included in Cost of goods sold on the accompanying Statement of
 Consolidated Operations as electricity purchases were made under
 the contract.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 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 September 2016.&#xA0;Beyond the
 term where market information is available, management has
 developed a forward curve, for valuation purposes, based on
 independent consultant market research.&#xA0;Significant increases
 or decreases in the power market may result in a higher or lower
 fair value measurement.&#xA0;Lower prices in the power market would
 cause a decrease in the derivative asset.&#xA0;The derivative
 contract has been designated as a cash flow hedge of future
 purchases of electricity.&#xA0;Unrealized gains and losses on this
 contract were recorded in Other comprehensive loss on the
 accompanying Consolidated Balance Sheet.&#xA0;Once the designated
 hedge period begins in September 2016, realized gains and losses
 will be recorded in Cost of goods sold as electricity purchases are
 made under the power contract.</p>

 <b>O. Proposed Separation Transaction</b> &#x2013; On September 28,
 2015, Alcoa announced that its Board of Directors approved a plan
 to separate into two independent, publicly-traded companies: An
 Upstream Company, the new Alcoa, that will primarily comprise the
 Alumina and Primary Metals segments; and a Value-Add Company,
 Arconic, that will principally include the Global Rolled Products,
 Engineered Products and Solutions, and Transportation and
 Construction Solutions segments. The Company currently plans that
 upon separation, which is targeted in the second half of 2016, the
 new Alcoa will also become owner of the rolling mill at the
 Warrick, IN Operations and the stake in the Ma&#x2019;aden Rolling
 Company in Saudi Arabia.</p>
 <p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px">
 &#xA0;</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt">
 The transaction is subject to a number of conditions, including,
 but not limited to, final approval by Alcoa&#x2019;s Board of
 Directors, receipt of a favorable opinion of legal counsel with
 respect to the tax-free nature of the transaction for U.S. federal
 income tax purposes, and the effectiveness of a Form 10
 registration statement to be filed with the U.S. Securities and
 Exchange Commission. Upon completion of the separation, Alcoa
 shareholders will own all of the outstanding shares of both
 companies. Alcoa may, at any time and for any reason until the
 proposed transaction is complete, abandon the separation plan or
 modify or change its terms. For the first quarter of 2016, Alcoa
 recognized $18 ($17 after-tax) in Selling, general administrative,
 and other expenses on the accompanying Statement of Consolidated
 Operations for costs related to the proposed transaction.</p>
