Accumulated Other Comprehensive Income (Loss), Net of Tax [Abstract]  
Accumulated Other Comprehensive Income
Accumulated Other Comprehensive Income
The table below shows the accumulated balances for components of other comprehensive income, net of tax. The largest component is the unrealized holding gains and losses on available for sale 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. The other component is pension gains and losses that arise during the period but are not recognized as components on net periodic benefit cost, and corresponding adjustments when these gains and losses are subsequently amortized to net periodic benefit cost.
