At September 30, 2014, the Company held 126 individual fixed maturity securities and two equity securities that were in an unrealized loss position, of which 21 individual fixed maturity securities were in a continuous unrealized loss position for longer than 12 months. The Company holds investments in a long/short equity fund, accounted for under the equity method. The carrying value of this investment is $11.2 million at September 30, 2014. Investment income is recognized as it is earned. The discount or premium on fixed maturity securities is amortized using the “constant yield” method. Anticipated prepayments, where applicable, are considered when determining the amortization of premiums or discounts. Realized investment gains and losses are determined using the specific identification method. We regularly review our investment portfolio to evaluate the necessity of recording impairment losses for other-than-temporary declines in the fair value of our investments. We consider various factors in determining if a decline in the fair value of an individual security is other-than-temporary. The key factors we consider are:
| • |  | any reduction or elimination of dividends, or nonpayment of scheduled principal or interest payments;
| • |  | the financial condition and near-term prospects of the issuer of the applicable security, including any specific events that may affect its operations or earnings;
| • |  | how long and by how much the fair value of the security has been below its cost or amortized cost;
| • |  | any downgrades of the security by a rating agency;
| • |  | our intent not to sell the security for a sufficient time period for it to recover its value;
| • |  | the likelihood of being forced to sell the security before the recovery of its value; and
| • |  | an evaluation as to whether there are any credit losses on debt securities.
We reviewed all securities with unrealized losses in accordance with the impairment policy described above. The Company expects to hold investments in equity securities for a reasonable period of time sufficient for a recovery of fair value. With the exception of one security deemed to be other-than-temporarily impaired, the Company determined that the unrealized losses in the fixed maturity securities portfolio related primarily to changes in market interest rates since the date of purchase, current conditions in the capital markets and the impact of those conditions on market liquidity and prices generally, and the transfer of the investments from the available-for-sale classification to the held-to-maturity classification in January 2004. We expect to recover the carrying value of these securities as it is not more likely than not that we will be required to sell the security before the recovery of its amortized cost basis. During the third quarter of 2014, the Company impaired a fixed maturity security in the amount of $0.2 million. The impairment charge is included in “Net realized gains (losses) on investments” for 2014. We impaired the security due to a recent downgrade of the security and the amount of the accumulated unrealized loss. Net realized gains in the nine months ended September 30, 2014 were $0.2 million resulting from $0.4 million in gains on called fixed maturity securities offset by an impairment loss of $0.2 million recognized for the other-than-temporary decline in the fair value of a fixed maturity security. Net realized losses in the nine months ended September 30, 2013 were $1.9 million due to $2.2 million of impairment losses recognized for other-than-temporary declines in the fair value of certain equity securities offset by realized gains of $0.2 million.
