Certain investments in debt securities are reported in the financial statements at an amount less than their historical cost. Total fair value of these investments at September 30, 2012 and December 31, 2011, respectively, was approximately $11.1 million and $172.6 million, which is approximately 1.4% and 19.7% of the Company’s available-for-sale and held-to-maturity investment portfolio, respectively.

Based on evaluation of available evidence, including recent changes in market interest rates, credit rating information and information obtained from regulatory filings, management believes the declines in fair value for these debt securities are temporary at September 30, 2012.

During the nine months ended September 30, 2012, the Company determined that the impairment of a non-agency collateralized mortgage obligation with a book value of $962,000 had become other than temporary.  Consequently, the Company recorded a $262,000 pre-tax charge to income.  During the nine months ended September 30, 2011, the Company determined that the impairment of a non-agency collateralized mortgage obligation with a book value of $1.8 million had become other than temporary.  Consequently, the Company recorded a $400,000 pre-tax charge to income.

The following table shows the Company’s gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at September 30, 2012 and December 31, 2011:

Gross gains of $572,000 and $483,000 and gross losses of $66,000 and $0 resulting from sales of available-for-sale securities were realized for the three months ended September 30, 2012 and 2011, respectively.  Gross gains of $2.7 million and $483,000 and gross losses of $625,000 and $0 resulting from sales of available-for-sale securities were realized for the nine months ended September 30, 2012 and 2011, respectively.

Other-than-temporary Impairment.  Upon acquisition of a security, the Company decides whether it is within the scope of the accounting guidance for beneficial interests in securitized financial assets or will be evaluated for impairment under the accounting guidance for investments in debt and equity securities.

The accounting guidance for beneficial interests in securitized financial assets provides incremental impairment guidance for a subset of the debt securities within the scope of the guidance for investments in debt and equity securities.  For securities where the security is a beneficial interest in securitized financial assets, the Company uses the beneficial interests in securitized financial asset impairment model.  For securities where the security is not a beneficial interest in securitized financial assets, the Company uses the debt and equity securities impairment model.  The Company does not currently have securities within the scope of this guidance for beneficial interests in securitized financial assets.

The Company conducts periodic reviews to identify and evaluate each investment security to determine whether an other-than-temporary impairment has occurred.  The Company considers the length of time a security has been in an unrealized loss position, the relative amount of the unrealized loss compared to the carrying value of the security, the type of security and other factors.  If certain criteria are met, the Company performs additional review and evaluation using observable market values or various inputs in economic models to determine if an unrealized loss is other-than-temporary.  The Company uses quoted market prices for marketable equity securities and uses broker pricing quotes based on observable inputs for equity investments that are not traded on a stock exchange.  For non-agency collateralized mortgage obligations, to determine if the unrealized loss is other-than-temporary, the Company projects total estimated defaults of the underlying assets (mortgages) and multiplies that calculated amount by an estimate of realizable value upon sale in the marketplace (severity) in order to determine the projected collateral loss.  The Company also evaluates any current credit enhancement underlying these securities to determine the impact on cash flows.  If the Company determines that a given security position will be subject to a write-down or loss, the Company records the expected credit loss as a charge to earnings.

Credit Losses Recognized on Investments.  Certain debt securities have experienced fair value deterioration due to credit losses. 

The following table provides information about debt securities for which only a credit loss was recognized in income and other losses are recorded in other comprehensive income.
