8. Other Comprehensive Income
     Activity in other comprehensive income (loss) for the three and six months ended June 30, 2011 and 2010 is shown in the table below. The first component of other comprehensive income is the unrealized holding gains and losses on available for sale securities. These gains and losses have been separated into two groups in the table below, as required by current accounting guidance for other-than-temporary impairment (OTTI) on debt securities. Under this guidance, credit-related losses on debt securities with OTTI are recorded in current earnings, while the noncredit-related portion of the overall gain or loss in fair value is recorded in other comprehensive income (loss). Changes in the noncredit-related gain or loss in fair value of these securities, after OTTI was initially recognized, are shown separately in the table below. The remaining unrealized holding gains and losses shown in the table apply to available for sale investment securities for which OTTI has not been recorded (and include holding gains and losses on certain securities prior to the recognition of OTTI).
     In the calculation of other comprehensive income, certain reclassification adjustments are made to avoid double counting gains and losses that are included as part of net income for a period that also had been included as part of other comprehensive income in that period or earlier periods. These reclassification amounts are shown separately in the table below.
     The second component of other comprehensive income is pension gains and losses that arise during the period but are not recognized as components of net periodic benefit cost, and corresponding adjustments when these gains and losses are subsequently amortized to net periodic benefit cost.
