All trends are Stable.

The rating confirmations reflect the overall stable performance of the transaction and generally healthy financial performance. The pool has a strong weighted-average (WA) debt service coverage ratio (DSCR) of 2.28 times (x); however, DBRS Morningstar notes that the transaction’s high concentration of loans collateralized by office properties, representing 25.4% of the pool balance, poses increased credit risk as there is an element of uncertainty around future demand for the property type. In general, the office sector’s performance has been strained, given the low investor appetite for the property type and high vacancy rates in many submarkets as a result of the shift in workplace dynamics. In the analysis for this review, loans backed by office properties and other properties that were showing performance declines from issuance or exhibiting increased risks from issuance were analyzed with stressed scenarios to increase the expected losses as applicable. The resulting WA expected loss for the stressed office loans is approximately 20.0% higher than the pool’s average expected loss.

As of the July 2023 remittance, 65 of the original 68 loans remain in the trust, with an outstanding trust balance of $1.2 billion resulting in a collateral reduction of 4.1% since issuance because of loan repayments/liquidation and scheduled amortization. Two loans, representing 7.4% of the current pool balance, are fully defeased. Five loans, representing 9.8% of the current pool balance, are on the servicer’s watchlist, primarily because of low DSCRs, occupancy concerns, and/or recent transfers back to the master servicer from the special servicer. One loan, representing 0.8% of the balance at issuance, liquidated from the pool in September 2021 with a loss of approximately $1.3 million contained to the nonrated Class G. There are currently no loans in special servicing.

The largest loan on the servicer’s watchlist, Wisconsin Hotel Portfolio (Prospectus ID#4, 5.4% of the pool balance), is secured by the borrower's fee-simple interests in a portfolio of 11 hotel properties with a combined 1,255 keys located across five submarkets in Wisconsin. The loan was added to the servicer’s watchlist in November 2020 for a low DSCR, reported at -0.24x at YE2020. Based on the financials for the trailing 12 month (T-12) period ended March 31, 2023, the loan reported a DSCR of 0.53x, an improvement from the YE2020 figure and relatively unchanged from the YE2022 figure of 0.55x, but still well below breakeven. Occupancy has not improved since the onset of the Coronavirus Disease (COVID-19) pandemic, hovering around 40% to 50%, while the pre-pandemic occupancy rate was reported at 63.7% as of YE2019. However, average daily rate and revenue per available room (RevPAR) has improved with the T-12 March 31, 2023, figures at $144.50 and $57.55, respectively, compared with the YE2020 figures of $84.57 and $33.12, respectively, but ultimately still below the YE2019 figures of $101.76 and $64.65, respectively. Despite the year-over-year RevPAR growth, performance continues to be well below DBRS Morningstar expectations. As such, DBRS Morningstar applied a probability of default penalty in its analysis, resulting in an expected loss that was nearly triple the pool’s WA expected loss.

At issuance, DBRS Morningstar shadow-rated two loans, Apple Campus 3 (Prospectus ID#1, 7.6% of the pool balance) and Moffett Towers II (Prospectus ID#10, 3.3% of the pool balance), as investment grade. With this review, DBRS Morningstar maintained the shadow ratings of the loans as they continue to perform in line with the investment-grade characteristics.
