Accumulated Other Comprehensive Income (Loss), Net of Tax [Abstract]  
Accumulated Other Comprehensive Income (Loss)
Accumulated Other Comprehensive Income (Loss)
The table below shows the activity and accumulated balances for components of other comprehensive income (loss). The largest component is the unrealized holding gains and losses on available for sale debt securities. Unrealized gains and losses on debt securities for which an other-than-temporary impairment (OTTI) has been recorded in current earnings are shown separately below. Another component is amortization from other comprehensive income of losses associated with pension benefits, which occurs as the amortization is included in current net periodic benefit cost. The remaining component is gains and losses in fair value on certain interest rate floors that have been designated as cash flow hedging instruments.

(1) The pre-tax amounts reclassified from accumulated other comprehensive income to current earnings are included in "investment securities gains (losses), net" in the consolidated statements of income.
(2) The pre-tax amounts reclassified from accumulated other comprehensive income to current earnings are included in "interest and fees on loans" in the consolidated statements of income.

The requirement to revalue deferred tax assets and liabilities in the period of enactment stranded the effects of the tax rate change, mandated by the Tax Cuts and Jobs Act, in accumulated other comprehensive income. In response, the FASB issued ASU 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income", which the Company adopted on January 1, 2018. This ASU allowed the reclassification of the stranded tax effects from accumulated other comprehensive income (loss) (as shown in the table above) to retained earnings.
As mentioned in Note 1, new accounting guidance for investment securities, which was effective January 1, 2018, required the reclassification of unrealized gains on equity securities from accumulated other comprehensive income (loss) to retained earnings (also shown above).
