The Company regularly reviews its investment portfolio to evaluate the necessity of recording impairment losses for other-than-temporary declines in the fair value of our investments. The Company considers various factors in determining if a decline in the fair value of an individual security is other-than-temporary. The key factors considered 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.
The Company reviewed all securities with unrealized losses in accordance with the impairment policy described above. 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. The Company expects to recover the carrying value of these securities since management does not intend to sell the securities and it is not more likely than not that the Company will be required to sell the security before the recovery of its amortized cost basis. In addition, none of the unrealized losses on debt securities are considered credit losses.
