Background and Basis of Presentation	Background and Basis of Presentation ▪Background: At December 31, 2016, Altria Group, Inc.’s wholly-owned subsidiaries included Philip Morris USA Inc. (“PM USA”), which is engaged in the manufacture and sale of cigarettes in the United States; John Middleton Co. (“Middleton”), which is engaged in the manufacture and sale of machine-made large cigars and pipe tobacco and is a wholly-owned subsidiary of PM USA; and UST LLC (“UST”), which through its wholly-owned subsidiaries, including U.S. Smokeless Tobacco Company LLC (“USSTC”) and Ste. Michelle Wine Estates Ltd. (“Ste. Michelle”), is engaged in the manufacture and sale of smokeless tobacco products and wine. Altria Group, Inc.’s other operating companies included Nu Mark LLC (“Nu Mark”), a wholly-owned subsidiary that is engaged in the manufacture and sale of innovative tobacco products, and Philip Morris Capital Corporation (“PMCC”), a wholly-owned subsidiary that maintains a portfolio of finance assets, substantially all of which are leveraged leases. Other Altria Group, Inc. wholly-owned subsidiaries included Altria Group Distribution Company, which provides sales, distribution and consumer engagement services to certain Altria Group, Inc. operating subsidiaries, and Altria Client Services LLC, which provides various support services in areas, such as legal, regulatory, finance, human resources and external affairs, to Altria Group, Inc. and its subsidiaries. Altria Group, Inc.’s access to the operating cash flows of its wholly-owned subsidiaries consists of cash received from the payment of dividends and distributions, and the payment of interest on intercompany loans by its subsidiaries. At December 31, 2016, Altria Group, Inc.’s principal wholly-owned subsidiaries were not limited by long-term debt or other agreements in their ability to pay cash dividends or make other distributions with respect to their equity interests. At September 30, 2016, Altria Group, Inc. had an approximate 27% ownership of SABMiller plc (“SABMiller”), which Altria Group, Inc. accounted for under the equity method of accounting. On October 10, 2016, Anheuser-Busch InBev SA/NV (“Legacy AB InBev”) completed a business combination with SABMiller in a cash and stock transaction (the “Transaction”). A newly formed Belgian company, which retained the name Anheuser-Busch InBev SA/NV (“AB InBev”), became the holding company for the combined SABMiller and Legacy AB InBev businesses. Upon completion of the Transaction, Altria Group, Inc. had a 9.6% ownership of AB InBev based on AB InBev’s shares outstanding at October 10, 2016. Following completion of the Transaction, Altria Group, Inc. purchased 12,341,937 ordinary shares of AB InBev for a total cost of approximately $1.6 billion, thereby increasing Altria Group, Inc.’s ownership to approximately 10.2%. At December 31, 2016, Altria Group, Inc. had an approximate 10.2% ownership of AB InBev, which Altria Group, Inc. accounts for under the equity method of accounting using a one-quarter lag. As a result of the one-quarter lag and the timing of the completion of the Transaction, no earnings from Altria Group, Inc.’s equity investment in AB InBev were recorded for the year ended December 31, 2016. Altria Group, Inc. receives cash dividends on its interest in AB InBev if and when AB InBev pays such dividends. For further discussion, see Note 7. Investment in AB InBev/SABMiller. ▪Basis of Presentation: The consolidated financial statements include Altria Group, Inc., as well as its wholly-owned and majority-owned subsidiaries. Investments in which Altria Group, Inc. has the ability to exercise significant influence are accounted for under the equity method of accounting. All intercompany transactions and balances have been eliminated. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the dates of the financial statements and the reported amounts of net revenues and expenses during the reporting periods. Significant estimates and assumptions include, among other things, pension and benefit plan assumptions, lives and valuation assumptions for goodwill and other intangible assets, marketing programs, income taxes, and the allowance for losses and estimated residual values of finance leases. Actual results could differ from those estimates. Certain prior year amounts have been reclassified to conform with the current year’s presentation due primarily to Altria Group, Inc.’s 2016 adoptions of Accounting Standards Update (“ASU”) No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (“ASU No. 2015-17”) and ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU No. 2015-03”). For further discussion, see Note 15. Income Taxes and Note 10. Long-Term Debt.
