(A)The reclassification from accumulated other comprehensive income (loss) to interest expense was related to terminated interest rate contracts. The current period charge in 2020 and 2019 relates to losses on the interest rate contracts entered into in November 2018 and June 2018 that were terminated in 2020. The current period credit in 2018 relates to the gain on the interest rate contract terminated in 2018. For additional information, see Note 10: Derivative Financial Instruments.

(B)Amortization of net losses and prior service costs was reclassified from accumulated other comprehensive income (loss) to other income (expense) – net.

(C)During 2018, we adopted ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allowed us to reclassify the stranded income tax effects resulting from the Tax Act from accumulated other comprehensive income (loss) to retained earnings.
