KBRA assigns preliminary ratings to Wells Fargo Mortgage Backed Securities Trust 2021-1 (WFMBS 2021-1)


NEW YORK–() – Kroll Bond Rating Agency (KBRA) assigns preliminary ratings to 36 classes of mortgage transfer certificates from Wells Fargo Mortgage Backed Securities Trust 2021-1 (WFMBS 2021-1). KBRA notes that this transaction is commercialized during the global coronavirus pandemic (COVID-19) and that none of the loans are on an active forbearance plan by the deadline.

Wells Fargo Mortgage Backed Securities Trust 2021-1 (WFMBS 2021-1) is a premier RMBS transaction comprising 390 residential mortgages with a total principal balance of $ 404.1 million as of the March 1, 2021 deadline. The underlying collateral consists entirely of non-conforming, fully amortizing fixed rate mortgages, all of which have been designated as Qualified Mortgages (QMs).

KBRA’s scoring approach incorporated a loan-level analysis of the mortgage pool through its US RMBS mortgage default and loss model, a review of the results of due diligence of third-party loan files, a modeling analysis of cash flow of the transaction payment structure, reviews of key transaction parties and an assessment of the legal structure and documentation of the transaction. This analysis is described in more detail in our US RMBS rating methodology.
