For purposes of the maturity table, mortgage-backed securities, which are not due at a single maturity date, have been allocated over maturity groupings based on the weighted-average contractual maturities of underlying collateral. The mortgage-backed securities generally mature earlier than their weighted-average contractual maturities because of principal prepayments. The following table reflects gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, as of September 30, 2015 and December 31, 2014.

Management evaluates securities for other-than-temporary impairment no less frequently than quarterly and more frequently when economic or market concerns warrant such evaluation. Consideration is given to (i) the length of time and the extent to which fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer and (iii) whether the Company intends to sell securities, and whether it is more likely than not that the Company will be required to sell the securities before recovery of their amortized cost bases. As of September 30, 2015, seven debt securities had been in a loss position for more than twelve months, and 77 debt securities had been in a loss position for less than twelve months. The losses for all securities are considered to be a direct result of the effect that the current interest rate environment has on the value of debt securities and are not related to the creditworthiness of the issuers. Further, the Company has the current intent and ability to retain its investments in each issuer for a period of time that management believes to be sufficient to allow for any anticipated recovery in fair value. Therefore, the Company has not recognized any other-than-temporary impairments. Investment securities available-for-sale with a carrying value of $52.1 million and $61.1 million as of September 30, 2015 and December 31, 2014, respectively, were pledged to secure public deposits and for other purposes. Gains realized on sales of securities available-for-sale were approximately $0.4 million and $0.1 million for the nine months ended September 30, 2015 and September 30, 2014, respectively. There were no losses on sales of securities during the nine months ended September 30, 2015 or September 30, 2014.
