In 2018, Non-service related net periodic benefit cost included lower net actuarial losses as a result of pension actions taken during 2018 (see Note G) and Other, net included a benefit from establishing a tax indemnification receivable of $29 reflecting Alcoa Corporation’s 49% share of a Spanish tax reserve (see Note U). In 2017, Net loss (gain) from asset sales included a gain on the sale of a portion of Arconic’s investment in Alcoa Corporation common stock of $351 (see Note V) and a gain of $167 on the Debt-for-Equity Exchange (see Note V). In 2017, Other, net included an adjustment of $81 to the contingent earn-out liability related to the 2014 acquisition of Firth Rixson (see Note T) and an adjustment of $25 associated with a separation-related guarantee liability (see Note U). In 2016, Non-service related net periodic benefit cost included a reduction of the recognition of actuarial losses and a methodology change in the calculation of interest cost, which were partially offset by the reduction in the expected return on plan assets. In 2016, Other, net included an adjustment of $56 to the contingent earn-out liability and a post-closing adjustment of $20, both related to the acquisition of Firth Rixson.
