All of the Company’s debt and equity securities are classified as AFS and are carried at fair value. The Company evaluates whether AFS securities are other-than-temporarily impaired (OTTI) based on criteria that include the extent to which cost exceeds market value, the duration of the market value decline, the credit rating of the issuer or security, the failure of the issuer to make scheduled principal or interest payments and the financial health and prospects of the issuer or security.

Declines in the value of AFS securities determined to be OTTI are recognized in earnings and reported as OTTI losses. Debt securities with unrealized losses are considered OTTI if the Company intends to sell the debt security or if the Company will be required to sell the debt security prior to any anticipated recovery. If the Company determines that a debt security is OTTI under these circumstances, the impairment recognized in earnings is measured as the difference between the amortized cost and the current fair value. A debt security is also determined to be OTTI if the Company does not expect to recover the amortized cost of the debt security. However, in this circumstance, if the Company does not intend to sell the debt security and will not be required to sell the debt security, the impairment recognized in earnings equals the estimated credit loss as measured by the difference between the present value of expected cash flows and the amortized cost of the debt security. Expected cash flows are discounted using the debt security’s effective interest rate. An equity security is determined to be OTTI if the Company does not expect to recover the cost of the equity security. Declines in the value of AFS securities determined to be temporary are reported, net of tax, as other comprehensive losses and included as a component of stockholders’ equity.

Interest and dividend income, amortization of premiums, accretion of discounts and realized gains and losses on AFS securities are included in investment income. Interest income is accrued as earned. Dividend income is recognized as income on the ex-dividend date of the stock. The cost of AFS securities sold is based on the first-in, first-out method.
