In light of the ongoing fiscal uncertainty in state and local governments, the Company analyzes its exposure to potential losses in its security portfolio on at least a quarterly basis. Management reviews the underlying credit rating and analyzes the financial condition of the respective issuers. Based on this analysis, the Company sold certain securities representing obligations of state and political subdivisions that were classified as held to maturity during 2013. The securities sold showed significant credit deterioration in that an analysis of the financial condition of the respective issuers showed the issuers were operating at net deficits with little to no financial cushion to offset future contingencies. The securities sold in 2013 had carrying values of $4,292, and the Company recognized a net gain of $169 on the sales during the year ended December 31, 2013. No securities classified as held to maturity were sold during the years ended December 31, 2014 or December 31, 2012.

The Company does not intend to sell any of the securities in an unrealized loss position, and it is not more likely than not that the Company will be required to sell any such security prior to the recovery of its amortized cost basis, which may be maturity. Furthermore, even though a number of these securities have been in a continuous unrealized loss position for a period greater than twelve months, the Company has experienced an overall improvement in the fair value of its investment portfolio on account of the decrease in interest rates from the prior year and is collecting principal and interest payments from the respective issuers as scheduled. As such, the Company did not record any other-than-temporary impairment for the years ended December 31, 2014 or 2013.

The Company holds investments in pooled trust preferred securities that had a cost basis of $26,400 and $27,531 and a fair value of $19,756 and $17,671 at December 31, 2014 and 2013, respectively. The investments in pooled trust preferred securities consist of four securities representing interests in various tranches of trusts collateralized by debt issued by over 320 financial institutions. Management’s determination of the fair value of each of its holdings in pooled trust preferred securities is based on the current credit ratings, the known deferrals and defaults by the underlying issuing financial institutions and the degree to which future deferrals and defaults would be required to occur before the cash flow for the Company’s tranches is negatively impacted. In addition, management continually monitors key credit quality and capital ratios of the issuing institutions. This determination is further supported by quarterly valuations, which are performed by third parties, of each security obtained by the Company. The Company does not intend to sell the investments, and it is not more likely than not that the Company will be required to sell the investments before recovery of the investments’ amortized cost, which may be at maturity. At December 31, 2014, management did not, and does not currently, believe such securities will be settled at a price less than the amortized cost of the investment, but the Company previously concluded that it was probable that there had been an adverse change in estimated cash flows for all four trust preferred securities and recognized credit related impairment losses on these securities in 2010 and 2011. For the years ended December 31, 2014, 2013, and 2012, the Company determined the pooled trust preferred securities and their estimated cash flow were fairly valued, and no additional impairment was recognized during these periods.

The Company's analysis of the pooled trust preferred securities in 2014 supported a return to accrual status for two of the four securities (XIII and XXIII.) An observed history of principal and interest payments combined with improved qualitative and quantitative factors described above justified the accrual of interest on these securities. However, one of the remaining securities (XXIV) is still in "payment in kind" status where interest payments are not expected until a future date, and, although the Company has received principal payments from the fourth security (XXVI), the Company's analysis of the qualitative and quantitative factors described above does not justify a return to accrual status at this time. As a result, pooled trust preferred securities XXIV and XXVI remain classified as nonaccruing assets at December 31, 2014, and investment interest is recorded on the cash-basis method until qualifying for return to accrual status.

The following table provides information regarding the Company’s investments in pooled trust preferred securities at December 31, 2014:



Name	Single/ Pooled	Class/ Tranche	Amortized Cost		Fair Value		Unrealized Gain (Loss)			Lowest Credit Rating	Issuers Currently in Deferral or Default
