All trends are Stable.

The rating confirmations and Stable trends reflect the generally stable performance of the transaction and positive developments for several loans since DBRS Morningstar’s last surveillance rating action in October 2021. As Coronavirus Disease (COVID-19) restrictions have eased across the United States within the past year, retail and hotel properties have significantly benefitted, including some that collateralize loans representing over 50% of the subject pool balance. In addition, one formerly specially serviced loan, 120 NE 39th Street Miami (Prospectus ID#14, 2.0% of the current pool balance), has returned to the master servicer and is no longer delinquent. The transaction also benefits from a moderate amount of defeasance, with 13 loans representing approximately 11% of the pool fully defeased. There are two small specially serviced loans in the pool, but DBRS Morningstar expects losses to be contained to the unrated Class NR certificate.

As of the August 2022 remittance, the trust consists of 84 of the original 87 loans with an aggregate principal balance of $844.7 million, reflecting a collateral reduction of approximately 10% since issuance. There are 14 loans, representing 25.7% of the pool, on the servicer’s watchlist. There are two loans, representing 1.3% of the pool, in special servicing, both of which are delinquent.

The largest loan in the transaction, Fairmont Orchid (Prospectus ID#1, 13.3% of the current pool), is secured by a full-service hotel in Kohala Coast, Hawaii. Hawaii implemented some of the strictest coronavirus restrictions in the United States, and many of those remained in place until March 2022. The loan was added to the servicer’s watchlist in November 2020 because of decreased occupancy and financial performance resulting from the coronavirus pandemic. At the time, the loan was reporting a below-breakeven net cash flow (NCF); however, as of YE2021, the property reported positive cash flow and a debt service coverage ratio (DSCR) of 2.14 times (x). Performance has since continued to improve, with a DSCR of 4.43x for the trailing 12 months (T-12) ended June 30, 2022, and NCF for the period reported at $19.1 million, well above the Issuer’s figure of $13.4 million, a product of an increase in revenue by more than $20 million from the Issuer’s figure. Prior to the onset of the pandemic, the loan consistently reported revenue and DSCR figures comfortably above the issuance figures. According to the May 2022 STR, Inc. report, the T-12 occupancy, average daily rate, and revenue per available room (RevPAR) figures were 60.6%, $503, and $305, respectively, with a T-12 RevPAR penetration rate of 78.7%.

The largest specially serviced loan, Dorsey Business Center III (Prospectus ID#48, 0.7% of the current pool), is secured by a Class B suburban office building in Elkridge, Maryland. The loan transferred to special servicing in October 2021 for payment default and remains delinquent. As of YE2021, the property was 42.1% occupied, falling from 91.8% at YE2019 after several tenants vacated the property at lease expiration. As a result, the DSCR is below breakeven. The October 2021 appraisal revalued the property at $5.3 million, decreasing from $9.1 million at issuance. As of August 2022, a receiver is in place and the property is listed for sale. Based on the October 2021 appraisal, DBRS Morningstar liquidated the loan with this review, with a loss severity exceeding 30.0%.
