Other-Than-Temporary-Impairment

Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Investment securities classified as available-for-sale are generally evaluated for OTTI under ASC Topic 320, “Investments - Debt and Equity Securities.”

In determining OTTI under the ASC Topic 320 model, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time.

All rated securities are investment grade. For those that are not rated, the financial condition has been evaluated and no adverse conditions were identified related to repayment. Declines in fair value are a function of rate differences in the market and market illiquidity. The Company does not intend or is not expected to be required to sell these securities before recovery of their amortized cost basis.

96.4% of the Company’s unrealized losses 12 months or more relate to its investment in a single trust preferred security. The security is a single-issuer trust preferred that is not rated. No impairment charge is being taken as no loss of principal or interest is anticipated. All principal and interest payments are being received as scheduled. On a quarterly basis, we evaluate the creditworthiness of the issuer, a bank holding company with operations in the state of Kentucky. Based on the issuer’s continued profitability and well-capitalized position, we do not deem that there is credit loss. The decline in fair value is primarily attributable to illiquidity affecting these markets and not the expected cash flows of the individual securities. We have evaluated the financial condition and near term prospects of the issuer and expect to fully recover our cost basis. This security continues to pay interest as agreed and future payments are expected to be made as agreed. This security is not considered to be other-than-temporarily impaired.
