[1] This amount is required to be recorded as other-than-temporary impairment through earnings. In measuring the portion of credit losses, Newcastle's management estimates the expected cash flows for each of the securities. This evaluation includes a review of the credit status and the performance of the collateral supporting those securities, including the credit of the issuer, key terms of the securities and the effect of local, industry and broader economic trends. Significant inputs in estimating the cash flows include management's expectations of prepayment speeds, default rates and loss severities. Credit losses are measured as the decline in the present value of the expected future cash flows discounted at the investment's effective interest rate.
[2] This amount represents unrealized losses on securities that are due to non-credit factors and is required to be recorded through other comprehensive income.
