Includes other-than-temporarily impaired (OTTI) AFS debt securities on which an OTTI loss, primarily related to changes in interest rates, remains in accumulated OCI.
The Corporation had $4 million and $27 million of credit-related OTTI losses on AFS debt securities which were recognized in other income for the three months ended March 31, 2018 and 2017. The amount of noncredit-related OTTI losses, which is recognized in OCI, was insignificant for all periods presented.
The cumulative credit loss component of OTTI losses that have been recognized in income related to AFS debt securities that the Corporation does not intend to sell was $278 million and $279 million at March 31, 2018 and 2017.
The Corporation estimates the portion of a loss on a security that is attributable to credit using a discounted cash flow model and estimates the expected cash flows of the underlying collateral using internal credit, interest rate and prepayment risk models that incorporate management’s best estimate of current key assumptions such as default rates, loss severity and prepayment rates. Assumptions used for the underlying loans that support the MBS can vary widely from loan to loan and are influenced by such factors as loan interest rate, geographic location of the borrower, borrower characteristics and collateral type. Based on these assumptions, the Corporation then determines how the underlying collateral cash flows will be distributed to each MBS issued from the applicable special purpose entity. Expected principal and interest cash flows on an impaired AFS debt security are discounted using the effective yield of each individual impaired AFS debt security.
Significant assumptions used in estimating the expected cash flows for measuring credit losses on non-agency residential mortgage-backed securities (RMBS) were as follows at March 31, 2018.

The value of a variable below which the indicated percentile of observations will fall.
Annual constant prepayment speed and loss severity rates are projected considering collateral characteristics such as loan-to-value (LTV), creditworthiness of borrowers as measured using Fair Isaac Corporation (FICO) scores, and geographic concentrations. The weighted-average severity by collateral type was 16.4 percent for prime, 17.6 percent for Alt-A and 27.9 percent for subprime at March 31, 2018. Default rates are projected by considering collateral characteristics including, but not limited to, LTV, FICO and geographic concentration. Weighted-average life default rates by collateral type were 15.1 percent for prime, 20.0 percent for Alt-A and 22.4 percent for subprime at March 31, 2018.
The remaining contractual maturity distribution and yields of the Corporation’s debt securities carried at fair value and HTM debt securities at March 31, 2018 are summarized in the table below. Actual duration and yields may differ as prepayments on the loans underlying the mortgages or other asset-backed securities (ABS) are passed through to the Corporation.
