16. CHANGE IN ACCUMULATED OTHER COMPREHENSIVE LOSS

Accumulated other comprehensive loss includes unrealized gains and losses on available-for-sale investments, unrealized gains and losses on cash flow hedges, as well as unrecognized prior service costs and actuarial gains and losses on defined benefit pension plans. Changes to accumulated other comprehensive loss are presented, net of tax, as a component of stockholders’ equity. Amounts that are reclassified out of accumulated other comprehensive loss are recorded on the unaudited Consolidated Statements of Income either as a gain or loss. Changes to accumulated other comprehensive loss by component are shown, net of taxes, in the following tables for the period indicated:
