NEW YORK--(BUSINESS WIRE)--Fitch Ratings has removed the rating outlooks from distressed securities in U.S. Scratch and Dent RMBS transactions. As a policy Fitch does not maintain Rating Outlooks on distressed securities. The removal of the outlooks has no effect on the long term credit ratings of the distressed classes. This is an amendment to the Nov. 16, 2012 rating actions.
On Nov. 16, 2012 Fitch Ratings took various rating actions on 948 classes in 144 U.S. Scratch and Dent RMBS transactions.
The transactions reviewed are generally comprised of residential mortgage loans which were either (a) originated with exceptions to the originator's underwriting guidelines or (b) delinquent, or had been previously delinquent, at the time of issuance. The reviewed transactions were issued between 1996 and 2008.
A spreadsheet detailing Fitch's rating actions can be found using the web link below for 'U.S. Scratch & Dent RMBS Rating Actions for Nov. 16, 2012'.
A summary of the rating actions:
--781 classes affirmed;
--167 classes downgraded.
The majority of the rating revisions affected classes which held non-investment grade or distressed ratings prior to the review. Additionally, the majority of the revisions were one rating category and no rating revision was greater than two categories.
Delinquency trends for the mortgage pools have remained relatively stable over the past year. On average, delinquency percentages improved modestly from 36% to 35%, while realized losses to date increased modestly from 11% to 12%.
The rating revisions primarily reflect revised assumptions for future loan modifications, servicer advancing and liquidation timelines to better reflect recent trends. Additionally, projected default assumptions were revised based on a recently-introduced non-prime loan loss model. The new model incorporates recent performance data and improves the consistency of methodologies across the Prime, Alt-A and Subprime sectors.
For mortgage pools without loan-level information, Fitch used vintage average default assumptions adjusted for each pool's delinquency distribution and performance. The loss-severity assumptions for all pools reflected loss severity trends of loans liquidated over the past 12 months. After determining each underlying pool's projected base-case and stressed scenario mortgage loss assumptions, Fitch performed cash flow analysis to determine the risk of principal loss or interest shortfall for each class.
