Accumulated Other Comprehensive Income (Loss) | ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)The sole component of accumulated other comprehensive income (loss) (“AOCI”) relates to activity in the accounting for pension and postretirement health and life benefit plans. The amortization of prior service costs (credits) are reclassified from AOCI and included in the computation of net periodic benefit cost. In 2019, the effect of pension plan changes related to lump sum payment options has been added to AOCI as an unrecognized prior service cost to be amortized over the average future service of active employees starting in 2020. For further details, refer to Note 12, Pension and Postretirement Health and Life Benefits.
