4. Investments (continued) As of December 31, 2012, there were approximately 32 securities in an unrealized loss position with a fair value of $397,186 and unrealized losses of $8,016. Of these securities, there are 9 securities that have been in an unrealized loss position for 12 months or greater with a fair value of $143,853 and unrealized losses of $5,445. Other-Than-Temporary Impairments ("OTTI") We review our investment portfolio for impairment on a quarterly basis. Impairment of investments results in a charge to operations when a fair value decline below cost is deemed to be other-than-temporary. As of June 30, 2013, we reviewed our portfolio to evaluate the necessity of recording impairment losses for other-than-temporary declines in the fair value of investments. During the three and six months ended June 30, 2013 and 2012, the Company recognized no OTTI. Based on our qualitative and quantitative OTTI review of each asset class within our fixed maturity portfolio, the unrealized losses on fixed maturities at June 30, 2013 were primarily due to widening of credit spreads relating to the market illiquidity, rather than credit events. Because we do not intend to sell these securities and it is not more likely than not that we will be required to sell these securities until a recovery of fair value to amortized cost, we currently believe it is probable that we will collect all amounts due according to their respective contractual terms. Therefore, we do not consider these fixed maturities to be other-than-temporarily impaired at June 30, 2013. The following summarizes the credit ratings of our fixed maturities:
