1 Amounts of actuarial loss and prior service cost are components of net periodic benefit cost. See note 18 above for additional details. 2 We reclassified certain tax effects from tax law changes of $16 million from "Accumulated other comprehensive loss" to "Retained earnings" on our Consolidated Balance Sheet in accordance with ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which we adopted in 2018. Foreign currency translation adjustments exclude income tax expense (benefit) given that these adjustments arise out of the translation of assets into the reporting currency that is separate from the taxable income and is deemed to be reinvested for an indefinite period of time. The pension adjustments included an income tax provision of $2 million, $1 million and $3 million in 2020, 2019 and 2018, respectively.
