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

DBRS, Inc. (DBRS Morningstar) took rating actions on 579 classes from 33 U.S. residential mortgage-backed security (RMBS) transactions. Of the 579 classes reviewed, DBRS Morningstar upgraded six ratings, confirmed 569 ratings, and discontinued four ratings.

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 ratings reflect the transactions exercising their cleanup call option or the full repayment of principal to bondholders.

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

The pools backing these RMBS transactions consist of pre-crisis 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 on the subject notes reflect additional seasoning warranted to substantiate a further upgrade and deal or tranche performance that is not fully reflected in the projected model output:
