KBRA Affirms and Upgrades Ratings from 68 RMBS Credit Risk Transfer Transactions

KBRA recently reviewed the ratings from 68 RMBS Credit Risk Transfer (CRT) transactions, resulting in 1,694 rating affirmations and 451 rating upgrades. The related transactions are listed further below with links to the appropriate page on kbra.com which show the applicable resulting ratings. The affirmations reflect generally stable collateral and structure performance, as evidenced by increased credit support for rated classes and minimal losses since issuance. The rating upgrades considered each security’s credit support relative to KBRA’s updated loss expectations, as well as the generally positive performance trends exhibited by the related underlying pool since issuance.

KBRA performed its analysis in accordance with its RMBS methodology. In performing these rating actions, KBRA considered transaction performance to date, updated home values via home price indexation, updated expected loss estimates, and capital structure behavior under various cash flow stress scenarios, where applicable. The rating actions, along with related deal and tranche performance information, are available in spreadsheet form in the accompanying KBRA RMBS Surveillance KCAT report.

Certain subordinate classes of the transactions listed below may have experienced losses and/or interest shortfalls. However, KBRA notes that none of the rated classes have experienced losses.

We note that, in general, these RMBS assets and liabilities can have long weighted average lives and structural features that provide for changes in payment priority over time. KBRA often considers seasoning in determining the extent of positive rating actions effectuated in a manner that also considers a transaction’s structure. This includes features such as the remaining size of more senior certificates, principal payments to subordinate tranches, and credit enhancement floor provisions. These features are weighed against, among other things, the tenor of the rated classes and the length of performance history associated with the collateral pool. In light of these considerations, KBRA has taken the rating actions as discussed above, determining that the rated classes were able to withstand the rating stresses applied within an acceptable tolerance.
