Securities Held-To-Maturity [Abstract] |
Securities Held-To-Maturity | Note 9—Securities Held to Maturity There were no held-to-maturity debt securities as of December 31, 2011 and 2010. On June 30, 2010, First Commonwealth reclassified its entire held-to-maturity portfolio to the available-for-sale portfolio. At the time of reclassification, the investments had an amortized cost of $22.4 million of which $22.3 million were obligations of states and political subdivisions and $0.1 million were mortgage backed securities. When the securities were transferred, two of the obligations of states and political subdivision securities were in an unrealized loss position totaling $45 thousand, the remaining bonds in that category were in an unrealized gain position of $0.8 million and all of the mortgage backed securities were in an unrealized gain position. In 2010, other-than-temporary impairment charges of $45 thousand were recognized on the two states and political subdivision securities that were in an unrealized loss position when transferred to available-for-sale. During the years ended December 31, 2010 and 2009, gross gains of $50 thousand and $53 thousand, respectively, were recognized on investments called. The transfer of securities from the held-to-maturity portfolio resulted from the implementation of a strategy to liquidate a portion of the obligations of states and political subdivisions portfolio in order to mitigate future credit risk and improve our tax position.
