Effective January 1, 2018, we adopted ASU 2016-01, which applies to equity investments that are neither (i) accounted for under the equity method or (ii) result in consolidation. Under ASU 2016-01 we record such investments at fair value and recognize any changes directly in net income, unless there is no readily ascertainable fair value, in which case we record the investment at cost less impairment. For fiscal periods beginning prior to January 1, 2018, marketable securities not accounted for under the equity method were classified as available-for-sale. Unrealized gains and losses on equity securities classified as available-for-sale were recognized in other comprehensive income. When we adopted ASU 2016-01 on January 1, 2018, we reclassified $31 million of previously recognized fair value gains from accumulated other comprehensive income to retained earnings.

Income taxes associated with each component of other comprehensive income were nil for the six months ended June 30, 2019 (Successor) (June 30, 2018 (Predecessor): nil).
