DBRS Takes Rating Action on U.S. RMBS Securities

DBRS has today reviewed 402 classes from 24 U.S. residential mortgage-backed security (RMBS) transactions. Of the 402 classes reviewed, 36 classes were upgraded, 363 classes were confirmed and three classes were downgraded. Of the confirmed classes, ten ratings were subsequently discontinued as the notes were fully repaid. All of the classes reviewed were also removed from Under Review with Developing Implications (see “DBRS Publishes Updated U.S. RMBS Surveillance Methodology and Places Ratings Under Review with Developing Implications,” published on March 3, 2014).

The transactions that have been upgraded have exhibited positive performance trends and have experienced increases in credit support sufficient to withstand stresses at their new rating level. For transactions where the rating has been confirmed, current asset performance and credit support levels have been consistent with the current rating. The downgrades taken reflect a combination of the continued erosion of credit support in these transactions as a result of negative trends in delinquency and projected loss activity.

The rating actions are the result of DBRS applying its updated “U.S. RMBS Surveillance Methodology” and “RMBS Insight 1.2: U.S. Residential Mortgage-Backed Securities Model and Rating Methodology.”

The transactions affected by the rating actions consist of U.S. resecuritization of real estate mortgage investment conduit (ReREMIC) transactions. A majority of the pools backing these transactions consist of primarily prime and Alt-A residential loans.

Notes:
The applicable methodologies are U.S. RMBS Surveillance Methodology and RMBS Insight 1.2: U.S. Residential Mortgage-Backed Securities Model and Rating Methodology, which can be found on our website under Methodologies.

These ratings are endorsed by DBRS Ratings Limited for use in the European Union.
