AOCI is reported as a component of stockholders’ equity. AOCI can include, among other items, unrealized holding gains and losses on securities available for sale (“AFS”), gains and losses associa ted with pension or other post-retirement benefits that are not recognized immediately as a component of net periodic benefit cost, and gains and losses on derivative instruments that are designated as, and qualify as, cash flow hedges. Net unrealized gains/losses on AFS securities reclassified as securities held to maturity (“HTM”) also continue to be reported as a component of AOCI and will be amortized over the estimated remaining life of the securities as an adjustment to interest income. Subject to certain thresholds, unrealized losses on employee benefit plans will be reclassified into income as pension and post-retirement costs are recognized over the remaining service period of plan participants. Accumulated gains/losses on the cash flow hedge of the variable rate loans describe d in Note 6 will be reclassified into income over the life of the hedge. Gains (losses) in AOCI are net of deferred income taxes. The following table shows the line items of the consolidated statements of income affected by amounts reclassified from AOCI. ﻿ ﻿
