At September 30, 2011, the combined depreciation in value of the 24 individual securities in an unrealized loss position was approximately 5.11% of the combined reported value of the aggregate securities portfolio. At December 31, 2010, the combined depreciation in value of the 214 individual securities in an unrealized loss position was approximately 5.93% 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 non-beneficial 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. Non-beneficial interest debt securities consist of U. S. government agency 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 credit related impairment and records any credit related OTTI through earnings and the non-credit related OTTI through other comprehensive income (“OCI”). During the three- and nine-month periods ended September 30, 2011, the Company incurred no OTTI charges related to non-beneficial interest debt securities. The 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 pooled trust preferred securities, corporate FDIC insured, and mortgage-backed securities. 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 non-credit related OTTI is accounted for in OCI. During the three- and nine-month periods ended September 30, 2011, the Company incurred credit-related OTTI charges related to beneficial interest debt securities of $210 thousand and $737 thousand, respectively. These charges were related to a non-Agency mortgage-backed security (“MBS”). During the three-month period ended September 30, 2010, the Company incurred no credit-related OTTI charges related to beneficial interest debt securities. During the nine-month period ended September 30, 2010, the Company incurred credit-related OTTI charges on beneficial interest debt securities of $134 thousand. These charges were related to two pooled trust preferred security holdings and brought the carrying value of those securities to zero. For the non-Agency, Alt-A residential MBS, the Company models cash flows using the following assumptions: voluntary constant prepayment speed of 5, a customized constant default rate scenario that assumes approximately 23% of the remaining underlying mortgages will default, and a loss severity of 60. The table below provides a cumulative roll forward of credit losses recognized in earnings for debt securities for which a portion of an OTTI is recognized in OCI:
(In Thousands) |  | For the Three Months Ended September 30, 2011 |  |  | For the Nine Months Ended September 30, 2011 |
Estimated credit losses, beginning balance (1) |  | $ | 4,778 |  |  | $ | 4,251 |
Additions for credit losses on securities not previously OTTI |  |  | — |  |  |  | — |
Additions for credit losses on securities previously OTTI |  |  | 210 |  |  |  | 737 |
Reduction for increases in cash flows |  |  | — |  |  |  | — |
Reduction for securities management no longer intends to hold to recovery |  |  | — |  |  |  | — |
Reduction for realized losses |  |  | — |  |  |  | — |
Estimated credit losses, ending balance |  | $ | 4,988 |  |  | $ | 4,988 |
(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 three- and nine-month periods ended September 30, 2011, the Company did not recognize any OTTI charges on equity securities. For the three months ended September 30, 2010, the Company recognized no OTTI charges on its equity securities. For the nine months ended September 30, 2010, the Company recognized OTTI charges on certain of its equity securities of $51 thousand. As a condition to membership in the Federal Home Loan Bank (“FHLB”) system, the Company is required to subscribe to a minimum level of stock in the FHLB of Atlanta (“FHLBA”). The Company believes this ownership position provides access to relatively inexpensive wholesale and overnight funding. The Company accounts for FHLBA and Federal Reserve Bank stock as a long-term investment in other assets. At September 30, 2011, and December 31, 2010, the Company owned approximately $11.14 million and $12.24 million, respectively, in FHLBA stock, which is classified as other assets. The Company’s policy is to review for impairment of such assets at the end of each reporting period. Based on the Company’s review of publicly available information about the FHLBA and its own internal analysis, the Company believes that its FHLBA stock was not impaired as of September 30, 2011.
