Unrealized losses on debt securities are generally due to higher current market yields relative to the yields of the debt securities at their amortized cost. Unrealized losses due to credit risk associated with the underlying collateral of the debt security, if any, are not material. All securities with unrealized losses are reviewed quarterly to determine if any impairment is considered other than temporary, requiring a write-down to fair market value. First Financial considers the percentage loss on a security, duration of the loss, average life or duration of the security, credit rating of the security, as well as payment performance and the company’s intent and ability to hold the security to maturity when determining whether any impairment is other than temporary. At this time First Financial does not intend to sell, and it is not more likely than not that the Company will be required to sell debt security issues temporarily impaired prior to maturity or recovery of book value. First Financial had no other than temporary impairment charges for the six months ended June 30, 2011.
