KBRA Assigns Preliminary Ratings to BANK 2018-BNK15

Kroll Bond Rating Agency (KBRA) is pleased to announce the assignment of preliminary ratings to 17 classes of BANK 2018-BNK15 (see ratings list below), a $1.1 billion CMBS conduit transaction collateralized by 67 commercial mortgage loans secured by 126 properties.

The collateral properties are located in 32 states, with three state exposures each representing more than 10.0% of the pool balance: California (19.3%), New York (16.8%), and Florida (10.8%). The pool has exposure to all of the major property types, with three each representing 10.0% or more of the pool balance: retail (45.2%), office (17.0%), and lodging (16.2%). The loans have principal balances ranging from $1.3 million to $100.0 million for the largest loan in the pool, Aventura Mall (9.2%), which is secured by 1.2 million sf of Aventura Mall, a 2.2 million sf, super-regional mall located in Aventura, Florida, approximately 18 miles north of the Miami CBD. The five largest loans, which also include Starwood Hotel Portfolio (9.2%), Millennium Partners Portfolio (6.9%), 685 Fifth Avenue Retail (5.5%), and Moffett Towers “ Buildings E,F,G (5.2%), represent 36.1% of the initial pool balance, while the top 10 loans represent 52.4%.

KBRAs 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 KBRAs estimate of sustainable net cash flow (KNCF) and KBRA value using our U.S. CMBS Property Evaluation Methodology. On an aggregate basis, KNCF was 7.4% less than the issuer cash flow. KBRA capitalization rates were applied to each assets KNCF to derive values that were, on an aggregate basis, 38.1% less than third party appraisal values. The pool has an in-trust KLTV of 86.1% and an all-in KLTV of 97.9%. 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.

For complete details on the analysis, please see our pre-sale report, BANK 2018-BNK15 published at www.kbra.com. The report includes our BANK 2018-BNK15 KBRA Conduit Comparative Analytic Tool (KCAT), an easy to use, Excel-based workbook that provides the following information:

  • KBRA Deal Tape “ Contains KBRA loan level details for every loan in the pool, and the ability for users to input adjustments to KNCF and KBRA Cap Rates and see the related impact on key deal metrics.
