DBRS Morningstar Takes Rating Actions on 74 U.S. RMBS Transactions

RMBS
January 31, 2020

DBRS, Inc. (DBRS Morningstar) reviewed 649 classes from 74 U.S. residential mortgage-backed security (RMBS) transactions. Of the 649 classes reviewed, DBRS Morningstar upgraded 25 ratings, confirmed 490 ratings, and discontinued 134 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 are the result of the 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 September 2018.

The pools backing these RMBS transactions consist of prime, subprime, Alt-A, seasoned, reperforming, and ReREMIC 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 additional seasoning being warranted to substantiate a further upgrade.
