DBRS Takes Rating Action on U.S. RMBS Securities
RMBSDBRS has today reviewed 544 classes from 43 U.S. residential mortgage-backed security (RMBS) transactions. Of the 544 classes reviewed, 74 classes were upgraded, 468 classes were confirmed and two classes were downgraded. These classes 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 experienced increases in credit support sufficient to withstand stresses at their new rating level or have been linked to the rating of corporate entities providing credit support to the tranche or transaction. 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 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. RMBS transactions. A majority of the pools backing these transactions consists of primarily subprime, 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.
