All trends are Stable.
The credit rating confirmations reflect the overall stable performance of the transaction, which remains in line with DBRS Morningstar expectations, as exhibited by a healthy weighted-average pool debt service coverage ratio (DSCR) of 3.05 times (x) and no loans in special servicing. As of the September 2023 remittance, all 76 of the original loans remain in the pool with a marginal collateral reduction of 0.7% since issuance. To date, no loans have defeased from the pool. There are five loans, representing 1.6% of the pool balance, on the servicer’s watchlist, four of which are being monitored for deferred maintenance and one for failure to provide proof of insurance. The pool is concentrated with loans backed by office and retail properties that make up 27.5% and 25.0% of the pool balance, respectively.
The loans backed by office properties have generally illustrated stable performance since issuance. There is a notable concentration of government- and city-affiliated tenants among these loans, with three loans in the top 15 (accounting for 10.6% of the pool balance) that were 100% leased to government or city agencies. However, given the challenges faced by the office sector as of late with low investor appetite for the property type and high vacancy rates in many submarkets as a result of the shift in workplace dynamics, DBRS Morningstar applied stress scenarios to its analysis, where applicable. This includes the One Trinity Center (Prospectus ID#11, 2.9% of the pool balance), which is secured by a Class B office property located in downtown San Francisco. The $40.0 million fixed-rate loan pays interest-only (IO) for the entirety of its 10-year term. The property was developed by the sponsor in 1990 and at issuance, it was noted that approximately $13.0 million of renovations were completed since 2017. The subject has exposure to government tenants, which is ideal considering the subject is in close proximity to the San Francisco City Hall. According to the June 2023 rent roll, occupancy was reported at 81.2% with tenants representing 56.9% of the net rentable area (NRA) rolling over in the next 12 months, including the largest tenants, City and County of San Francisco (27.4% of NRA, lease expiry in July 2024); the San Francisco Law Library (14.8% of the NRA, lease expiry in June 2023); and San Francisco City Health Service System (14.4% of the NRA, lease expiry in March 2024). However, the borrower is close to finalizing a renewal for San Francisco Law Library that would extend the lease to June 2028. Furthermore, per the Reis Q2 2023 report for the Van Ness/Civic Center submarket, the average vacancy rate was 28.7%, a steep increase from the Q1 2023 vacancy of 14.8%; however, it is expected to decrease to 14.4% in the next five years.
According to YE2022 financial reporting, the subject reported a net cash flow (NCF) and DSCR of $4.2 million and 3.55x, respectively, compared with the DBRS Morningstar NCF and DSCR of $3.4 million and 2.88x, respectively. While performance to date remains stable, the high rollover risk as well as the soft San Francisco office market are concerning. As such, DBRS Morningstar applied a stressed loan-to-value ratio and an elevated probability of default in its analysis for this review, resulting in an expected loss nearly triple the deal average.
At issuance, DBRS Morningstar shadow-rated three loans as investment-grade: Four Constitution (Prospectus ID#3, 4.0% of the pool balance), River House Coop (Prospectus ID#4 3.8% of the pool balance), and Three Constitution (Prospectus ID#12, 2.7% of the pool balance). These loans continue to exhibit strong credit characteristics consistent with investment-grade shadow ratings. The Four Constitution and Three Constitution loans are backed by office properties that are 100% occupied by the United States Department of Justice on 15-year leases with no termination options through maturity, while the River House Coop loan is backed by an exclusive co-operative apartment building in Manhattan that is of excellent property quality. With this review, DBRS Morningstar maintained shadow ratings on all three of the loans.
