DBRS Morningstar Takes Rating Actions on 21 U.S. RMBS Transactions

DBRS, Inc. (DBRS Morningstar) reviewed 165 classes from 21 U.S. residential mortgage-backed securities (RMBS) transactions. All 21 transactions are generally classified as reperforming transactions. Of the 165 classes reviewed, DBRS Morningstar upgraded 112 ratings and confirmed 53 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 ratings assigned to the securities listed below differ from the ratings implied by the quantitative model. DBRS Morningstar considers these differences material deviations; however, in these cases, the ratings on the subject securities may reflect additional seasoning being warranted to substantiate a further upgrade or that the actual deal or tranche performance is not fully reflected in the projected cash flows/model output.
