NEW YORK--(BUSINESS WIRE)--Kroll Bond Rating Agency, Inc. (KBRA) assigns ratings to six classes of mortgage pass-through certificates from Western Asset Management Company’s inaugural non-prime RMBS securitization, Arroyo Mortgage Trust 2018-1 (ARRW 2018-1).
Arroyo Mortgage Trust 2018-1 (ARRW 2018-1) is the first residential mortgage-backed securities (RMBS) transaction issued by the Sponsor (Arroyo Mortgage Acquisition Company I, LLC) an affiliate of Western Asset Management Company (WAMCO Fund). The transaction includes both seasoned performing (pre-implementation of the Ability-to Repay rule) and newly-originated non-prime collateral with a weighted average life (WAL) of 20.1 months. The loans were primarily underwritten using non-traditional income documentation sources to borrowers with substantial equity. The collateral pool contains both non-qualified mortgages (Non-QM) and loans that are exempt from the ATR rule such as: investor properties and loans originated prior to implementation of the Ability-to Repay rule. The $1.25 billion RMBS transaction is collateralized by a pool of 3,160 residential mortgages.
The underlying collateral consists of hybrid adjustable rate mortgages (96.4%) and fully-amortizing fixed-rate loans (3.6%), including interest only loans (1.7%) with seven-year interest only periods. Loans in the pool exhibit substantial borrower equity in each mortgaged property, as evidenced by the WA original LTV and CLTV of 60.8%. Additionally, ARRW 2018-1 exhibits the third lowest WA original LTV of any KBRA rated transaction. The weighted average original credit score is 743.
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 third-party loan file due diligence, 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.
