There were no held-to-maturity securities in a continuous unrealized loss position at March 31, 2012, or December 31, 2011.

 

The carrying value of securities pledged to secure public deposits and for other purposes was $270.46 million and $288.80 million at March 31, 2012, and December 31, 2011, respectively.

The following table details the Company’s gross gains and gross losses realized from the sale of securities for the three months ended March 31, 2012 and 2011.

At March 31, 2012, the combined depreciation in value of 41 individual securities in an unrealized loss position was 4.39% of the combined reported value of the aggregate securities portfolio. At December 31, 2011, the combined depreciation in value of 28 individual securities in an unrealized loss position was 4.51% of the combined reported value of the aggregate securities portfolio.

The Company reviews its investment portfolio on a quarterly basis for indications of other-than-temporary impairment (“OTTI”). The analysis differs depending upon the type of investment security being analyzed. For debt securities, the Company has determined that it does not intend to sell securities that are impaired and has asserted that it is not more likely than not that the Company will have to sell impaired securities before recovery of the impairment occurs. This determination is based upon the Company’s investment strategy for the particular type of debt security and its cash flow needs, liquidity position, capital adequacy, and interest rate risk position.

For nonbeneficial interest debt securities, the Company analyzes several qualitative factors such as the severity and duration of the impairment, adverse conditions within the issuing industry, prospects for the issuer, performance of the security, changes in rating by rating agencies, and other qualitative factors to determine if the impairment will be recovered. Nonbeneficial interest debt securities consist of U.S. treasury securities, states and political subdivisions, and single issue trust preferred securities. If it is determined that there is evidence that the impairment will not be recovered, the Company performs a present value calculation to determine the amount of impairment and records any credit-related OTTI through earnings and noncredit-related OTTI through OCI. During the quarters ended March 31, 2012, and March 31, 2011, the Company incurred no OTTI charges related to nonbeneficial interest debt securities. Temporary impairment on these securities is primarily related to changes in interest rates, certain disruptions in the credit markets, destabilization in the Eurozone, and other current economic factors.

For beneficial interest debt securities, the Company reviews cash flow analyses on each applicable security to determine if an adverse change in cash flows expected to be collected has occurred. Beneficial interest debt securities consist of corporate FDIC insured securities and mortgage-backed securities (“MBS”). An adverse change in cash flows expected to be collected has occurred if the present value of cash flows previously projected is greater than the present value of cash flows projected at the current reporting date and less than the current book value. If an adverse change in cash flows is deemed to have occurred, then an OTTI has occurred. The Company then compares the present value of cash flows using the current yield for the current reporting period to the reference amount, or current net book value, to determine the credit-related OTTI. The credit-related OTTI is then recorded through earnings and the noncredit-related OTTI is accounted for in OCI. During the quarter ended March 31, 2012, the Company incurred no credit-related OTTI charges on beneficial interest debt securities. During the quarter ended March 31, 2011, the Company incurred credit-related OTTI charges on beneficial interest debt securities of $527 thousand related to a non-Agency MBS.

For the non-Agency Alt-A residential MBS, the Company uses a discounted cash flow model with the following assumptions: voluntary constant prepayment rate of 5%, a customized constant default rate scenario that assumes approximately 17% of the remaining underlying mortgages will default within three years, and a loss severity rate of 60%.

 

The following table provides a cumulative roll forward of credit losses recognized in earnings for debt securities for which a portion of the OTTI is recognized in OCI:

   $ 6,536     $ 4,778  
   

 

 

    

 

 

  

 

(1) The beginning balance includes credit related losses included in OTTI charges recognized on debt securities in prior periods.

For equity securities, the Company reviews for OTTI based upon the prospects of the underlying companies, analysts’ expectations, and certain other qualitative factors to determine if impairment is recoverable over a foreseeable period of time. During the quarters ended March 31, 2012 and 2011, the Company recognized no OTTI charges on equity securities.

As a condition to membership in the Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) systems, the Company is required to subscribe to a minimum level of stock in the FHLB of Atlanta (“FHLBA”) and FRB of Richmond (“FRB Richmond”). The Company feels this ownership position provides access to relatively inexpensive wholesale and overnight funding. FHLBA and FRB Richmond stock are reported as long-term investments in “Other assets” on the Company’s “Condensed Consolidated Balance Sheets.” At March 31, 2012, and December 31, 2011, the Company owned $11.54 million and $10.82 million, respectively, of FHLBA stock. The Company’s policy is to review the stock for impairment at each reporting period. During the three months ended March 31, 2012, the FHLBA paid quarterly dividends and announced that it will repurchase excess activity-based stock during the second quarter of 2012. Based on the Company’s review and publicly available information concerning the FHLBA, it believes that as of March 31, 2012, its FHLBA stock was not impaired. At March 31, 2012, and December 31, 2011, the Company owned $4.78 million of FRB Richmond stock.
