Kroll Bond Rating Agency Assigns Preliminary Ratings to CSAIL 2017-C8

NEW YORK--()--Kroll Bond Rating Agency, Inc. (KBRA) is pleased to announce the assignment of preliminary ratings to 16 classes of the CSAIL 2017-C8 transaction (see ratings list below). CSAIL 2017-C8 is an $811.1 million CMBS conduit transaction collateralized by 32 commercial mortgage loans secured by 55 properties.

The properties in the collateral pool are located in 24 states, with only New York (33.1%) and California (19.2%) each representing more than 10.0% of the pool balance. The pool has exposure to all the major property types with the exception of self-storage and manufactured housing communities. There are four property types that each represent more than 10.0% of the pool balance: office (45.3%), lodging (14.5%), retail (14.5%) and mixed-use (12.1%).The loans have principal balances ranging from $5.0 million to $90.0 million for the largest loan in the pool, 85 Broad Street (11.1%), which is secured by a Class-A office building located in the Financial District of Lower Manhattan within New York City. The five largest loans, which also include 245 Park Avenue (9.9%), Apple Sunnyvale (8.7%), Ritz Carlton Rancho Mirage (6.7%), and Hotel Eastlund (5.1%), represent 41.3% of the initial pool balance, while the 10 largest loans represent 62.9%.

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 CMBS Property Evaluation Methodology. On an aggregate basis, KNCF was 6.7% 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, 43.0% less than third party appraisal values. The pool has an in-trust KLTV of 88.2% and an all-in KLTV of 113.3%. 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 presale report, CSAIL 2017-C8 published today at The report includes our KBRA 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.
  • KBRA Credit Metrics Comparison Tool – Enables the user to compare the subject transaction to a user-defined transaction comp set. The feature provides many of the fields that are included in our CMBS Monthly Trend Watch publication.
  • Excel-based property cash flow statements for the top 20 loans.
