Refer to Note D – Hedging Activities and Fair Value Measurements for further detail on our net investment hedges recorded in Foreign currency translation adjustments and our cash flow hedges recorded in Net change in derivative financial instruments. As a result of adopting ASC Update No. 2016-01 in the first quarter of 2018, we recorded a cumulative effect adjustment to retained earnings to reclassify unrealized gains and losses from our equity investments previously recorded to Accumulated other comprehensive income (loss), net of tax. These equity investments were classified as available-for-sale securities under the former accounting guidance, and we now refer to these investments as publicly-held equity securities. Refer to Note A – Significant Accounting Policies for additional information. The gains and losses on defined benefit and pension items before reclassifications and gains and losses on defined benefit and pension items reclassified from Accumulated other comprehensive income (loss), net of tax were reduced by immaterial income tax impacts in 2019 and in 2018.
