Kroll Bond Rating Agency Assigns Final Ratings to Sequoia Mortgage Trust 2013-4 Certificates

NEW YORK--(BUSINESS WIRE)--Kroll Bond Rating Agency (KBRA) assigns final ratings to seven classes of mortgage pass-through certificates from Sequoia Mortgage Trust 2013-4, a jumbo prime RMBS transaction. Concurrently we have withdrawn our preliminary ratings on the certificates, which were assigned on March 12, 2013.

The mortgage pool backing SEMT 2013-4 is comprised of 716 first-lien mortgage loans with an aggregate principal balance of $576,435,465 as of the cut-off date. Over 98% of the loans in the pool are 30-year fixed-rate mortgages; the remainder are 20-year and 25-year fixed mortgages. About 2.2% of the loans are interest-only for the first 10 years; the remainder are fully amortizing. The pool is characterized by substantial borrower equity in each mortgaged property, as evidenced by the average LTV (64%) and CLTV (65%). The weighted average credit score of the mortgage pool is 773 which is well within the prime mortgage range. The SEMT 2013-4 pool is also notable for offering even stronger levels of borrower equity.

KBRA’s analysis of the transaction included a loan-level analysis of the mortgage pools using our Residential Mortgage Default and Loss Model, together with a review of the transaction parties, results of loan file reviews performed by independent third party firms and review of the legal structure and key documentation. This analysis is further described in our U.S. RMBS Rating Methodology.
