Accumulated Other Comprehensive Income or Loss (“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”), including the Company’s share of unrealized gains and losses reported by a partnership accounted for under the equity method, gains and losses associated 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 and 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 or losses on cash flow hedges of variable rate loans described in Note 6 - Derivatives will be reclassified into income over the life of the hedge. Accumulated other comprehensive loss resulting from the terminated interest rate swaps are being amortized over the remaining maturities of the designated instruments. Gains and losses within AOCI are net of deferred income taxes, where applicable.

The following table shows the line items in the consolidated statements of income affected by amounts reclassified from AOCI.
