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 $12 million and $23 million of credit-related OTTI losses on AFS debt securities which were recognized in other income for the three and nine months ended September 30, 2018 compared to $0 and $33 million for the same periods in 2017. The amount of noncredit-related OTTI losses recognized in OCI was not significant for all periods presented.
The cumulative OTTI credit losses recognized in income on AFS debt securities that the Corporation does not intend to sell were $135 million and $284 million at September 30, 2018 and 2017.
For more information on OTTI losses and significant assumptions used for the Corporation’s underlying collateral, see Note 3 – Securities to the Consolidated Financial Statements of the Corporation’s 2017 Annual Report on Form 10-K. 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 September 30, 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 16.2 percent for prime, 16.4 percent for Alt-A and 22.2 percent for subprime at September 30, 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 16.1 percent for prime, 21.9 percent for Alt-A and 22.7 percent for subprime at September 30, 2018.
The remaining contractual maturity distribution and yields of the Corporation’s debt securities carried at fair value and HTM debt securities at September 30, 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.
