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.

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 December 31, 2014 and 2013, based on the aforementioned considerations, management did not record an other-than-temporary impairment on any security that was in an unrealized loss position.

The following table reflects the Company’s investments’ 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 December 31, 2014 and 2013.

As of December 31, 2014, 10 debt securities had been in a loss position for more than 12 months, and 31 debt securities had been in a loss position for less than 12 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 the issuer for a period of time that we believe to be sufficient to allow for any anticipated recovery in fair value. Therefore, the Company has not recognized any other-than-temporary impairments.
