In April 2016, Arconic’s majority-owned subsidiary, Alcoa of Australia Limited (AofA), sold its 20% interest in a consortium, DBP, the owner and operator of the Dampier to Bunbury Natural Gas Pipeline (DBNGP) in Western Australia, to the only other member of the consortium, DUET Group. AofA received $145 (A$192) in cash, which was included in Sales of investments on the accompanying Statement of Consolidated Cash Flows, and recorded a gain of $27 (A$35) ($11 (A$15) after-tax and noncontrolling interest) in Other income, net on the accompanying Statement of Consolidated Operations. Prior to this transaction, AofA’s 20% interest was previously classified as an equity investment on Arconic’s Consolidated Balance Sheet. 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. AofA is part of Alcoa World Alumina and Chemicals (AWAC), an unincorporated joint venture that consists of a group of companies, which are owned 60% by Arconic and 40% by Alumina Limited of Australia. In the 2016 nine-month period, Arconic sold various exchange-traded fixed income and equity securities held by its captive insurance company for $130, which was included in Sales of investments on the accompanying Statement of Consolidated Cash Flows, and recorded a loss of $3 ($2 after-tax) in Other income, net on the accompanying Statement of Consolidated Operations. Previously, these securities were classified as available-for-sale investments on Arconic’s Consolidated Balance Sheet and were carried at fair value with unrealized gains and losses recognized in other comprehensive income. As of September 30, 2016 and December 31, 2015, the carrying value of available-for-sale-securities was $83 and $193, respectively, which was included in Investments on the accompanying Consolidated Balance Sheet.
