U.S. Government agencies and corporations include callable and bullet agency issues and agency-backed mortgage backed securities. The maturity of mortgage backed securities is shown based on contractual maturity of the security although repayments occur each year.

The amortized cost and fair value of available for sale debt securities by contractual maturity date at December 31, 2013 is provided in the following table. Mortgage backed securities are not due at a single maturity date and are therefore shown separately.

The following table shows the proceeds from sales of available-for-sale securities for each of the three years ended December 31. The gross realized gains and losses on those sales that have been included in earnings.

The carrying value of securities pledged to secure trust deposits, public deposits, line of credit, and for other purposes required by law amounted to $154,479 and $150,197 at December 31, 2013 and 2012, respectively.

The following is a summary of securities that had unrealized losses at December 31, 2013 and 2012. The information is presented for securities that have been in an unrealized loss position for less than 12 months and for more than 12 months. At December 31, 2013, the Corporation held 53 securities with unrealized losses totaling $8,651. At December 31, 2012 there were 12 securities with unrealized losses totaling $338. There are temporary reasons why securities may be valued at less than amortized cost. Temporary reasons are that the current levels of interest rates as compared to the coupons on the securities held by the Corporation are higher and impairment is not due to credit deterioration. The Corporation has the intent and the ability to hold these securities until their value recovers, which may be until maturity.

On a quarterly basis, the Corporation performs a comprehensive security-level impairment assessment on all securities in an unrealized loss position to determine if other-than-temporary impairment ("OTTI") exists. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis. For debt securities, an OTTI loss must be recognized for a debt security in an unrealized loss position if the Corporation intends to sell the security or it is more likely than not that the Corporation will be required to sell the security before recovery of its amortized cost basis. In this situation, the amount of loss recognized in income is equal to the difference between the fair value and the amortized cost basis of the individual security. If the Corporation does not expect to sell the security, the Corporation must evaluate the expected cash flows to be received to determine if a credit loss has occurred. If a credit loss is present, only the amount of impairment associated with the credit loss is recognized in income. The portion of the unrealized loss relating to other factors, such as liquidity conditions in the market or changes in market interest rates, is recorded in other comprehensive income.

The security-level assessment is performed on each security, regardless of the classification of the security as available for sale or held to maturity. The assessments are based on the nature of the securities, the financial condition of the issuer, the extent and duration of the securities, the extent and duration of the loss and the intent and whether Management intends to sell or it is more likely than not that it will be required to sell a security before recovery of its amortized cost basis, which may be maturity. For those securities for which the assessment shows the Corporation will recover the entire cost basis, Management does not intend to sell these securities and it is not more likely than not that the Corporation will be required to sell them before the anticipated recovery of the amortized cost basis, the gross unrealized losses are recognized in other comprehensive income, net of tax.

Management does not believe that the investment securities that were in an unrealized loss position as of December 31, 2013 represent an other-than-temporary impairment. Total gross unrealized losses were primarily attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. The Corporation does not intend to sell the investment securities that were in an unrealized loss position and it is not more likely than not that the Corporation will be required to sell the investment securities before recovery of their amortized cost bases, which may be at maturity.
