DBRS Takes Rating Action on U.S. RMBS Securities
RMBSDBRS has today reviewed 568 classes from 41 U.S. residential mortgage-backed security (RMBS) transactions. Of the 568 classes reviewed, 183 classes were upgraded, 360 classes were confirmed and 25 classes were downgraded. Of the confirmed classes, fifteen classes were placed as Discontinued-Repaid due to full principal repayment to bondholders. 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 ratings have 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 the underlying 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. ReREMIC transactions. A majority of the pools backing these transactions consists primarily of 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.
