When the Company purchases a credit-sensitive AFS security at a significant discount to its face value, the Company often does not amortize into income a significant portion of this discount that the Company is entitled to earn because it does not expect to collect it due to the inherent credit risk of the security. The Company may also record an other-than-temporary impairment, or OTTI, for a portion of its investment in the security to the extent the Company believes that principal losses will exceed the discount. The amount of principal that the Company does not amortize into income is designated as a credit reserve on the security, with unamortized net discounts or premiums amortized into income over time using the interest method in accordance with ASC 320.
The following table presents the changes for the six months ended June 30, 2011 and June 30, 2010 of the unamortized net discount and designated credit reserves on non-Agency AFS securities.

Evaluating AFS Securities for Other-than-Temporary Impairments
The Company has adopted the provisions of ASC 320 to evaluate AFS securities for OTTI. This evaluation requires us to determine whether there has been a significant adverse quarterly change in the cash flow expectations for a security. The Company compares the amortized cost of each security in an unrealized loss position against the present value of expected future cash flows of the security. The Company also considers whether there has been a significant adverse change in the regulatory and/or economic environment as part of this analysis. If the amortized cost of the security is greater than the present value of expected future cash flows, an other-than-temporary credit impairment has occurred. If the Company does not intend to sell and is not more likely than not required to sell the security, the credit loss is recognized in earnings and the balance of the unrealized loss is recognized in other comprehensive income (loss). If the Company intends to sell the security or will be more likely than not required to sell the security, the full unrealized loss is recognized in earnings.
The Company recorded a $0.3 million other-than-temporary credit impairment during the quarter ended June 30, 2011 on one non-Agency RMBS where the future expected cash flows was less than its amortized cost. As of June 30, 2011, the impaired security had cumulative losses of 37.2%, three-month prepayment speed of 0.11, 60+ day delinquency of 14.1% of the pool balance, and weighted average FICO score of 691.
