Management evaluates each quarter whether unrealized losses on securities represent impairment that is other than temporary. For debt securities, the Company considers its intent to sell the securities or if it is more likely than not the Company will be required to sell the securities. If such impairment is identified, based upon the intent to sell or the more likely than not threshold, the carrying amount of the security is reduced to fair value with a charge to earnings. Upon the result of the aforementioned review, management then reviews for potential other than temporary impairment based upon other qualitative factors. In making this evaluation, management considers changes in market rates relative to those available when the security was acquired, changes in market expectations about the timing of cash flows from securities that can be prepaid, performance of the debt security, and changes in the market’s perception of the issuer’s financial health and the security’s credit quality. If determined that a debt security has incurred other than temporary impairment, then the amount of the credit related impairment is determined. If a credit loss is evident, the amount of the credit loss is charged to earnings and the non-credit related impairment is recognized through other comprehensive income.

As of June 30, 2015, 77 securities had unrealized losses totaling 1.42% of the individual securities’ amortized cost basis and 0.78% of the Company’s total amortized cost basis. Of the 77 securities, 20 had been in an unrealized loss position for over twelve months at June 30, 2015. These 20 securities had an amortized cost basis and unrealized loss of $62.3 million and $2.0 million, respectively. The unrealized losses on debt securities at June 30, 2015 resulted from changing market interest rates over the yields available at the time the underlying securities were purchased. Management identified no impairment related to credit quality. At June 30, 2015, management had the intent and ability to hold impaired securities and no impairment was evaluated as other than temporary. As a result, no other than temporary impairment losses were recognized during the three months ended June 30, 2015.

During the six months ended June 30, 2015, the Company sold 21 securities classified as available-for-sale at a net gain of $1.2 million. Of the 21 securities sold, 11 were sold with gains totaling $1.4 million and 10 securities were sold at a loss of $135,000. During the six months ended June 30, 2014, the Company sold 4 securities classified as available-for-sale at a net gain of $128,000. All of the securities were sold at a gain.

Securities with an aggregate carrying value of approximately $276.4 million and $279.8 million at June 30, 2015 and December 31, 2014, respectively, were pledged to secure public funds on deposit and for other purposes required or permitted by law.
