The amortization of actuarial losses and prior service cost is part of total net periodic retirement benefit cost when reclassified to net income.  Net periodic retirement benefit cost also includes service cost, interest cost, expected return on assets, and settlement losses.  Total service cost is allocated between cost of revenues and selling, general and administrative expenses on a plan-by-plan basis and the remaining net periodic retirement benefit cost items are allocated to interest and other income (expense):

Prior to adoption of ASU 2016-01 (see Note 1) in the first quarter of 2018, gains and losses on sales of available-for-sale securities were reclassified from accumulated other comprehensive loss to the condensed consolidated statements of operations when the gains or losses were realized.  Pretax amounts were classified in the condensed consolidated statements of operations as interest and other income (expense).
(c)
Pretax gains and losses on cash flow hedges are classified in the condensed consolidated statements of operations as:
•
other operating income (expense) (no gains or losses in the three months ended March 31, 2018 and $0.2 million of losses in the three months ended March 31, 2017)
•
interest and other income (expense) (no gains or losses in the three months ended March 31, 2018 and no gains or losses in the three months ended March 31, 2017).
