DBRS Morningstar Takes Rating Actions on 33 U.S. RMBS Transactions

DBRS, Inc. (DBRS Morningstar) reviewed 311 classes from 33 U.S. residential mortgage-backed security (RMBS) transactions. Of the 311 classes reviewed, DBRS Morningstar upgraded 19 ratings, confirmed 291 ratings, and discontinued one rating.

The rating upgrades reflect positive performance trends and increases in credit support sufficient to withstand stresses at their new rating levels. The rating confirmations reflect asset performance and credit-support levels that are consistent with the current ratings. The discontinued rating reflects a full repayment of principal to bondholders.

The rating actions are a result of DBRS Morningstar’s application of the “U.S. RMBS Surveillance Methodology” published in February 2020.

The pools backing these RMBS transactions consist of prime, Alt-A, option adjustable-rate mortgage, second-lien, and subprime collateral.

The ratings assigned to the securities below differ from the ratings implied by the quantitative model. DBRS Morningstar considers this difference to be a material deviation, but in this case, the ratings of the subject notes reflect either additional seasoning being warranted to substantiate a further upgrade or actual deal or tranche performance not being fully reflected in the projected cash flows/model output.
