Through direct and indirect ownership, the Company has 28 operating locations in nine countries around the world, situated primarily in Australia, Brazil, Canada, Iceland, Norway, Spain, and the United States.</p> <p style="margin-top:9pt;margin-bottom:0pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">References in these Notes to “ParentCo” refer to Alcoa Inc., a Pennsylvania corporation, and its consolidated subsidiaries through October 31, 2016, at which time it was renamed Arconic Inc. (Arconic) and since has been subsequently renamed Howmet Aerospace Inc.</p> <p style="margin-top:9pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-size:10pt;font-family:Times New Roman;font-style:normal;text-transform:none;font-variant: normal;">Separation Transaction.<span style="font-weight:normal;"> On November 1, 2016 (the Separation Date), ParentCo separated into two standalone, publicly-traded companies, Alcoa Corporation and ParentCo, effective at 12:01 a.m. Eastern Time (the Separation Transaction). Regular-way trading of Alcoa Corporation’s common stock began with the opening of the New York Stock Exchange on November 1, 2016 under the ticker symbol “AA.” The Company’s common stock has a par value of $0.01 per share.</span></p> <p style="margin-top:9pt;margin-bottom:0pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">In connection with the Separation Transaction, Alcoa Corporation and ParentCo entered into certain agreements to implement the legal and structural separation between the two companies, govern the relationship between the Company and ParentCo after the completion of the Separation Transaction, and allocate between Alcoa Corporation and ParentCo various assets, liabilities, and obligations. These agreements included a Separation and Distribution Agreement, Tax Matters Agreement, Employee Matters Agreement, Transition Services Agreement, certain Patent, Know-How, Trade Secret License and Trademark License Agreements, and Stockholder and Registration Rights Agreement.</p> <p style="margin-bottom:0pt;margin-top:9pt;text-indent:0%;font-weight:bold;font-size:10pt;font-family:Times New Roman;font-style:normal;text-transform:none;font-variant: normal;">Basis of Presentation.<span style="font-weight:normal;"> The Consolidated Financial Statements of Alcoa Corporation are prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). In accordance with GAAP, certain situations require management to make estimates based on judgments and assumptions, which may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. They also may affect the reported amounts of revenues and expenses during the reporting periods. Management uses historical experience and all available information to make these estimates, including considerations for the impact of the coronavirus (COVID-19) pandemic on the macroeconomic environment. The Company has experienced certain negative impacts as a result of the COVID-19 pandemic to date; however, the ultimate magnitude and duration of the COVID-19 pandemic continues to be unknown, and the pandemic’s ultimate future impact on the Company’s business, financial condition, operating results, cash flows, and market capitalization is uncertain. In addition, the COVID-19 pandemic could adversely impact estimates made as of December 31, 2020 regarding future results, such as the recoverability of goodwill and long-lived assets and the realizability of deferred tax assets. Despite these inherent limitations, management believes that the amounts recorded in the financial statements related to these items are based on its best estimates and judgments using all relevant information available at the time. Management regularly evaluates the judgments and assumptions used in its estimates, and results could differ from those estimates upon future events and their effects or new information. Certain amounts in previously issued financial statements were reclassified to conform to the current period presentation. </span></p> <p style="margin-top:9pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-size:10pt;font-family:Times New Roman;font-style:normal;text-transform:none;font-variant: normal;">Principles of Consolidation.<span style="font-weight:normal;"> The Consolidated Financial Statements of the Company include the accounts of Alcoa Corporation and companies in which Alcoa Corporation has a controlling interest, including those that comprise the Alcoa World Alumina &amp; Chemicals (AWAC) joint venture (see below). Intercompany transactions have been eliminated. The equity method of accounting is applied to investments in affiliates and other joint ventures over which the Company has significant influence but does not have effective control. Investments in affiliates in which Alcoa Corporation cannot exercise significant influence are accounted for on the cost method.</span></p> <p style="margin-top:9pt;margin-bottom:0pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">AWAC is an unincorporated global joint venture between Alcoa Corporation and Alumina Limited and consists of several affiliated operating entities, which own, have an interest in, or operate the bauxite mines and alumina refineries within the Company’s Bauxite and Alumina segments (except for the Poços de Caldas mine and refinery and portions of the São Luís refinery and investment in Mineração Rio do Norte S.A., all in Brazil) and a portion (55%) of the Portland smelter (Australia) within the Company’s Aluminum segment. Alcoa Corporation owns 60% and Alumina Limited owns 40% of these individual entities, which are consolidated by the Company for financial reporting purposes and include Alcoa of Australia Limited (AofA), Alcoa World Alumina LLC (AWA), Alcoa World Alumina Brasil Ltda. (AWAB), and Alúmina Española, S.A. (Española). Alumina Limited’s interest in the equity of such entities is reflected as Noncontrolling interest on the accompanying Consolidated Balance Sheet. </p> <p style="margin-top:9pt;margin-bottom:0pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Management evaluates whether an Alcoa Corporation entity or interest is a variable interest entity and whether the Company is the primary beneficiary. Consolidation is required if both of these criteria are met. Alcoa Corporation does not have any variable interest entities requiring consolidation.</p> <p style="margin-top:9pt;margin-bottom:0pt;text-indent:0%;font-weight:bold;font-size:10pt;font-family:Times New Roman;font-style:normal;text-transform:none;font-variant: normal;">Related Party Transactions.<span style="font-weight:normal;"> Alcoa Corporation buys products from and sells products to various related companies, consisting of entities in which the Company retains a 50% or less equity interest, at negotiated prices between the two parties. These transactions were not material to the financial position or results of operations of Alcoa Corporation for all periods presented.</span></p>
