KBRA Assigns Preliminary Ratings to OBX 2020-EXP1 Trust (OBX 2020-EXP1)

NEW YORK–(BUSINESS WIRE)–Kroll Bond Rating Agency (KBRA) assigns preliminary ratings to 43 classes of mortgage notes from OBX 2020-EXP1 Trust (OBX 2020-EXP1), a $467.5 million expanded prime RMBS transaction collateralized by loans with both traditional and alternative borrower documentation.

The $467.5 million RMBS transaction is collateralized by a pool of 722 residential mortgages, with fixed-rate mortgages (FRMs) and hybrid adjustable-rate mortgages (ARMs) making up 52.1% and 47.9% of the pool, respectively. Approximately 64.8% of the loans are classified as non-qualified mortgages (Non-QM, 64.8%) and 8.7% are categorized as qualified mortgages (QM). The remaining 26.5% of the pool are exempt from the Ability-to-Repay/Qualified Mortgage (ATR/QM) rule due to either being originated for non-consumer loan purposes or being originated prior to the rule’s effective date.

The OBX 2020-EXP1 mortgage is characterized by moderate borrower leverage and a combination of traditional and alternative income documentation, including full documentation (e.g. tax return, W-2), bank statements, written verification of employment and profit and loss statements. The borrowers in the pool have a non-zero weighted average (NZWA) original credit score of 756 and a NZWA debt-to-income (DTI) ratio of 37.7%. Borrowers in OBX 2020-EXP1 also exhibit considerable equity in each mortgaged property, as evidenced by the pool’s WA original loan-to-value (LTV) and combined LTV (CLTV) ratios of 67.8% and 68.1%, respectively. The pool has a WA loan age (WALA) of approximately seven months.

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.
