The Company primarily invests in mortgage-backed securities, variable and fixed rate corporate bonds, municipal bonds, government bonds and to a lesser extent equity securities. The policy of the Company is to recognize other than temporary impairment (OTTI) on equity securities where the fair value has been significantly below cost for three consecutive quarters. Declines in the fair value of the debt securities that can be attributed to specific adverse conditions affecting the credit quality of the investment would be recorded as OTTI and charged to earnings. In order to determine if a decline in fair value is other than temporary, the Company reviews corporate ratings of the investment, analyst reports and SEC filings of the issuers. For fixed maturity investments with unrealized losses due to interest rates where the Company expects to recover the entire amortized cost basis of the security, declines in value below cost are not assumed to be other than temporary. The Company reviews its position quarterly and has asserted that at September 30, 2013, the declines outlined in the above table represent temporary declines due to changes in interest rates and are not reflections of impairment in the credit quality of the securities. Additionally, the Company does not intend to sell the investment and it is not more likely than not that the Company will be required to sell the investment before recovery of its amortized cost basis.

The Company reviews investment debt securities on an ongoing basis for the presence of OTTI with formal reviews performed quarterly. Credit-related OTTI losses on individual securities are recognized in earnings while noncredit-related OTTI on securities not expected to be sold is recognized in accumulated other comprehensive income. There were no OTTI losses on individual securities during the quarter or nine months ended September 30, 2013.

The Company holds one pooled trust preferred security that has previously been determined to be other than temporarily impaired by approximately $2.0 million, due solely to credit related factors. This security is a collateralized debt obligation currently comprised of trust preferred securities of 9 financial institutions and has a Moody’s rating of Ca, which is below investment grade. The Company utilized an independent third party to analyze this bond at June 30, 2013, and it was determined that no additional impairment exists. At September 30, 2013 the Company utilized a discounted cash flow pricing method and determined no additional impairment exists.

Because of the subprime crisis, current markets for variable rate corporate trust preferred securities are illiquid. This includes the Company’s eight stand-alone trust preferred securities and the Company’s one pooled trust preferred security. The Company used a discounted cash flow method to price these securities due to a lack of liquidity for resale of this investment type and the absence of reliable pricing information. This method is described more fully in footnote 9, “Fair Value.”

For purposes of the maturity table, mortgage backed securities, which are not due at a single maturity date, have been allocated over maturity groupings based on weighted-average contractual maturities of underlying collateral. The mortgage-backed securities may mature earlier than their weighted-average contractual maturities because of principal prepayments.
