Investment in AB InBev	Investment in AB InBev: At September 30, 2018, Altria had an approximate 10.1% ownership of AB InBev, consisting of approximately 185 million restricted shares of AB InBev (the “Restricted Shares”) and approximately 12 million ordinary shares of AB InBev. Altria accounts for its investment in AB InBev under the equity method of accounting because Altria has the ability to exercise significant influence over the operating and financial policies of AB InBev, including having active representation on AB InBev’s Board of Directors (“AB InBev Board”) and certain AB InBev Board Committees. Through this representation, Altria participates in AB InBev policy making processes. Altria reviews its investment in AB InBev for impairment by comparing the fair value of its investment to its carrying value. If the carrying value of its investment exceeds its fair value and the loss in value is other than temporary, the investment is considered impaired and impairment is recognized in the period identified. The factors used to make this determination include the duration and magnitude of the fair value decline, AB InBev’s financial condition and near-term prospects, and Altria’s intent and ability to hold its investment in AB InBev until recovery. The fair value of Altria’s equity investment in AB InBev is based on: (i) unadjusted quoted prices in active markets for AB InBev’s ordinary shares and was classified in Level 1 of the fair value hierarchy and (ii) observable inputs other than Level 1 prices, such as quoted prices for similar assets for the Restricted Shares, and was classified in Level 2 of the fair value hierarchy. Altria may, in certain instances, pledge or otherwise grant a security interest in all or part of its Restricted Shares. In the event the pledgee or security interest holder forecloses on the Restricted Shares, the relevant Restricted Shares will be automatically converted, one-for-one, into ordinary shares. Therefore, the fair value of each Restricted Share is based on the value of an ordinary share. The fair value of Altria’s equity investment in AB InBev at September 30, 2018 and December 31, 2017 was $17.2 billion and $22.1 billion, respectively, compared with its carrying value of $17.8 billion and $18.0 billion, respectively. The fair value of Altria’s equity investment has continued to decline after September 30, 2018. On October 25, 2018, AB InBev announced a 50% rebase in the dividends it pays to its shareholders, which will result in a reduction of cash dividends AB InBev shareholders receive. The fair value of Altria’s equity investment at October 25, 2018 was approximately $14.5 billion. Based on its evaluation of the factors identified above, Altria concluded that the decline in fair value of its investment in AB InBev below its carrying value is temporary and, therefore, no impairment was recorded.
