Kroll Bond Rating Agency (KBRA) said recently it has assigned preliminary ratings to six classes of mortgage pass-through notes from OBX 2023-NQM1 Trust (OBX 2023-NQM1), a $405.2 million non-prime residential mortgage-backed securities (RMBS) transaction.
OBX 2023-NQM1 Trust was issued by Onslow Bay Financial LLC as seller/sponsor. Onslow Bay operates as a wholly owned subsidiary of Hatteras Financial Corp., which is owned by Annaly Capital Management Inc. Annaly purchases all residential whole loans through Onslow Bay.
The loans in the OBX 2023-NQM1 collateral pool were originated by relatively small, unrated entities and underwritten to non-traditional income documentation, KBRA said. With the exception of AmWest Funding Corp., the largest originator comprising 27.8% of the pool, each other originator contributed less than 15% of the mortgage loans.
The underlying collateral, comprising 842 residential mortgages, is characterized by a notable concentration of alternative income documentation (92%). Most of the loans (62.9%) are either classified as non-qualified mortgages (Non-QM) or exempt from the Ability-to-Repay/Qualified Mortgage (ATR/QM) rule due to being originated for non-consumer loan purposes (36.8%).
KBRA assigned the preliminary ratings as follows:
- A-1: AAA (sf)
- A-2: AA (sf)
- A-3: A- (sf)
- M-1: BBB (sf)
- B-1: BB (sf)
- B-2: B (sf)
- B-3, A-IO-S, XS, R: Not rated.
KBRA’s rating approach incorporated loan-level analysis of the mortgage pool through its KBRA RMBS Credit 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.
