KBRA Assigns Preliminary Ratings to 3650R 2021-PF1

NEW YORK--(BUSINESS WIRE)--Kroll Bond Rating Agency (KBRA) is pleased to announce the assignment of preliminary ratings to 16 classes of 3650R 2021-PF1, a $918.6 million CMBS conduit transaction collateralized by 35 commercial mortgage loans secured by 42 properties.

The collateral properties are located throughout 15 MSAs, of which the three largest are Los Angeles (22.2%), New York (13.9%) and Boston (8.5%). The pool has exposure to most major property types, with four types representing more than 15.0% of the pool balance: office (27.5%), retail (23.9%), multifamily (23.0%), and mixed-use (16.1%). The loans have principal balances ranging from $4.4 million to $77.9 million for the largest loan in the pool, CX - 350 & 450 Water Street (8.5%), which is secured by a 915,233 sf Class-A office and lab complex located in Cambridge, Massachusetts. The five largest loans, which also include 50 Horseblock (6.4%), Rox San (5.7%), 520 Almanor (5.4%), and Plaza La Cienega (5.4%), represent 31.5% of the initial pool balance, while the top 10 loans represent 53.5%.

KBRA’s analysis of the transaction incorporated our multi-borrower rating process that begins with our analysts' evaluation of the underlying collateral properties' financial and operating performance, which determine KBRA’s estimate of sustainable net cash flow (KNCF) and KBRA value using our U.S. CMBS Property Evaluation Methodology. On an aggregate basis, KNCF was 12.3% less than the issuer cash flow. KBRA capitalization rates were applied to each asset’s KNCF to derive values that were, on an aggregate basis, 45.0% less than third party appraisal values. The pool has an in-trust KLTV of 104.1% and an all-in KLTV of 113.5%. The model deploys rent and occupancy stresses, probability of default regressions, and loss given default calculations to determine losses for each collateral loan that are then used to assign our credit ratings.
