Investment Securities [Abstract] |
Investment Securities | 4. INVESTMENT SECURITIES The amortized cost and fair value of investment securities are shown in the following table. Management performs a quarterly evaluation of investment securities for any other-than-temporary impairment. During 2010, Park recognized an other-than-temporary impairment charge of $23,000, related to an equity investment in a financial institution, which is recorded in "other expenses" within the Consolidated Statements of Income. During 2009, Park recognized impairment losses of $0.6 million related to equity investments in several financial institutions. Since these are equity securities, no amounts were recognized in other comprehensive income at the time of the impairment recognition. Investment securities at December 31, 2010 were as follows:
|  |  |  |  | Gross |  |  | Gross |  |  |  |
|  |  |  |  | Unrealized |  |  | Unrealized |  |  |  |

Park's U.S. Government sponsored entity asset-backed securities consisted of 15-year residential mortgage-backed securities and collateralized mortgage obligations (CMOs). At December 31, 2010, the amortized cost of Park's AFS and held-to-maturity mortgage-backed securities was $988.5 million and $0.1 million, respectively. At December 31, 2010, the amortized cost of Park's AFS and held-to-maturity CMOs was $1.7 million and $670.3 million, respectively. Other investment securities (as shown on the Consolidated Balance Sheets) consist of stock investments in the Federal Home Loan Bank and the Federal Reserve Bank. Park owned $61.8 million of Federal Home Loan Bank stock and $6.9 million of Federal Reserve stock at December 31, 2010. Park owned $62.0 million of Federal Home Loan Bank stock and $6.9 million of Federal Reserve Bank stock at December 31, 2009. Management does not believe any individual unrealized loss as of December 31, 2010 or December 31, 2009, represents an other-than-temporary impairment. The unrealized losses on debt securities are primarily the result of interest rate changes. These conditions will not prohibit Park from receiving its contractual principal and interest payments on these debt securities. The fair value of these debt securities is expected to recover as payments are received on these securities and they approach maturity. Should the impairment of any of these securities become other-than-temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the other-than-temporary impairment is identified. The following table provides detail on investment securities with unrealized losses aggregated by investment category and length of time the individual securities had been in a continuous loss position at December 31, 2010:
