DBRS Morningstar Takes Rating Actions on 26 U.S. RMBS Transactions

DBRS, Inc. (DBRS Morningstar) reviewed 327 classes from 26 legacy U.S. residential mortgage-backed security (RMBS) transactions issued prior to the Great Recession. Of the 327 classes reviewed, DBRS Morningstar confirmed all classes.

Due to the potential economic hardship caused by Coronavirus Disease (COVID-19), DBRS Morningstar anticipates that delinquencies may arise in the coming months for many RMBS asset classes, some meaningfully. In the legacy sector, borrowers who recently defaulted and/or modified, or those who are currently “underwater,” may be most at risk for future defaults. However, these same borrowers have also weathered the last downturn and have generally accumulated some equity in their homes. In addition, compared with those in the prime jumbo sector, these borrowers are more likely to benefit from the direct-to-consumer economic support offered by the various government relief initiatives.

DBRS Morningstar will continue to monitor transactions across U.S. RMBS asset classes with respect to their exposure to coronavirus and will take necessary rating actions if performance deteriorates beyond expectation.

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 Alt-A, 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 securities 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.
