All trends are Stable. In addition, DBRS Morningstar discontinued the ratings on Classes A-1 and A-2 as they were fully repaid with the June 2022 remittance, following the repayment of the NKX Multifamily Portfolio loan.

The rating confirmations reflect the overall stable performance of the transaction, which has remained in line with DBRS Morningstar expectations since issuance. As of the June 2022 remittance, 47 of the original 49 loans remain in the pool, with an aggregate principal balance of $1.1 billion, reflecting a collateral reduction of 3.4% since issuance. There are seven loans on the servicer's watchlist and one loan in special servicing, representing 13.0% and 0.8% of the pool balance, respectively. One loan, representing 8.0% of the current pool balance, is fully defeased.

4440 East Tropicana Avenue (Prospectus ID#33, 0.8% of the current pool) is secured by a retail building in Las Vegas, Nevada. The loan transferred to special servicing in September 2020 for monetary default, and ownership of the property was transferred to the trust in March 2022. The special servicer is working toward stabilizing the property before selling. The former largest tenant, 24 Hour Fitness (79.8% of net rentable area (NRA)), declared bankruptcy and vacated the subject in June 2020. The borrower was unable to back-fill the space with H&P Tires Express, LLC (20.2% of NRA) remaining as the sole tenant on a lease through July 2029. The March 2022 appraisal reported a value of $6.0 million, which is unchanged from the June 2021 value but a 56.5% decrease from the issuance value of $13.8 million. DBRS Morningstar maintained its liquidation scenario in its analysis from last review, resulting in an implied loss severity in excess of 55.0%.

Three loans, representing 23.2% of the current pool balance, are shadow-rated investment grade by DBRS Morningstar: Park Tower at Transbay (Prospectus ID#1, 10.1% of the pool), 230 Park Avenue South (Prospectus ID#2, 9.6% of the pool), and Grand Canal Shoppes (Prospectus ID#10, 3.5% of the pool). The Grand Canal Shoppes loan has several pari passu pieces secured in several commercial mortgage backed securities (CMBS) transactions, including three rated by DBRS Morningstar (GSMS 2019-GC42, CGCMT 2019-GC41, and BMARK 2019-B12). With this review, DBRS Morningstar confirmed that these loans continue to perform in line with investment-grade loan characteristics.
