NEW YORK--(BUSINESS WIRE)--Kroll Bond Rating Agency (KBRA) assigns preliminary ratings to fifty-three classes of mortgage pass-through certificates from Agate Bay Mortgage Trust 2015-4 (ABMT 2015-4), a prime jumbo RMBS transaction.
The underlying ABMT 2015-4 mortgage pool comprises 319 first-lien, residential loans with an aggregate principal balance of $252,919,473 as of the cut-off date. ABMT 2015-4 represents the eighth RMBS transaction sponsored by TH TRS Corp. (a subsidiary of Two Harbors Investment Corp.) through the Agate Bay Mortgage Trust shelf. The mortgage pool consists entirely of fully amortizing fixed rate loans, all of which have 30-year maturities. The pool is characterized by substantial borrower equity in each mortgaged property, as evidenced by the weighted average LTV (63.7%) and CLTV (64.1%). The CLTV ratio incorporates 3.55% of the pool possessing known junior mortgages. The weighted average original credit score of the mortgage pool is 775, which is within the prime mortgage range.
KBRA’s rating approach incorporated loan-level analysis of the mortgage pool through its Residential Mortgage Default and Loss Model, an examination of the results from loan file reviews performed by independent third-party firms, cash flow modeling analysis of the transaction’s payment structure, reviews of key transaction parties and an assessment of the transaction’s legal structure and documentation. This analysis is further described in our U.S. RMBS Rating Methodology.
