No sales of available-for-sale securities occurred during the years ended December 31, 2015 and 2014.

At December 31, 2016 and 2015, securities with a fair value of $22.4 million and $23.0 million, respectively, were pledged to secure interest rate swap contracts, outstanding FHLB advances, if any, and additional FHLB availability.

The amortized cost and fair value of securities by contractual maturity at December 31, 2016 are shown below. Actual maturities may differ from contractual maturities because issuers have the right to call or prepay certain obligations without call or prepayment penalties.

The tables below show the Corporation’s gross unrealized losses and fair value of available-for-sale investments with unrealized losses aggregated by investment category and length of time that individual investments were in a continuous loss position at December 31, 2016 and 2015. At December 31, 2016, the Corporation held 108 available-for-sale securities that were in an unrealized loss position. Such securities have not experienced credit rating downgrades; however, they have primarily declined in value due to the current interest rate environment. At December 31, 2016, the Corporation held seven available-for-sale securities that had been in a continuous unrealized loss position for twelve months or greater.

The Corporation also has not specifically identified available-for-sale securities in a loss position that it intends to sell in the near term and does not believe that it will be required to sell any such securities. The Corporation reviews its securities on a quarterly basis to monitor its exposure to other-than-temporary impairment. Consideration is given to such factors as the length of time and extent to which the security has been in an unrealized loss position, changes in security ratings and an evaluation of the present value of expected future cash flows, if necessary. Based on the Corporation’s evaluation, it is expected that the Corporation will recover the entire amortized cost basis of each security. Accordingly, no other than temporary impairment was recorded in the Consolidated Statements of Income for the years ended December 31, 2016 and 2015.

A summary of unrealized loss information for securities available-for-sale, categorized by security type and length of time for which the security has been in a continuous unrealized loss position, follows:
