All trends are Stable with the exception of Class G, which has a rating that does not typically carry a trend in commercial mortgage-backed securities (CMBS) ratings. The rating confirmations reflect the overall stable performance of the underlying collateral, which remains in line with DBRS Morningstar’s expectations since the last review.

As of the May 2023 remittance report, 72 of the original 81 loans remain in the pool, representing a collateral reduction of 19.9% since issuance as a result of scheduled loan amortization, loan repayments, and one loan liquidation. There are 14 loans, representing 13.4% of the pool, that are fully defeased. Excluding collateral that has been defeased, the pool is most concentrated by retail, hotel, and office properties, with loans representing 23.4%, 22.1%, and 12.7% of the pool, respectively. There are currently 12 loans, representing 27.3% of the pool, on the servicer’s watchlist, generally being monitored for low debt service coverage ratios (DSCR).

While there is only one loan that is currently in special servicing, representing 0.7% of the pool, the borrower for the Westin Portland loan (Prospectus ID#8, 4.6% of the pool) has recently requested the loan be transferred back to the special servicer as it is unable to cover operational shortfalls, according to the servicer commentary. DBRS Morningstar’s analysis includes liquidation scenarios for both of these loans. The implied losses total more than $22.0 million, which would partially erode the balance of the first loss piece, Class H.

The Westin Portland loan is secured by a 19-story, full-service, 205-key luxury hotel in the central business district of Portland, Oregon. The loan was transferred to the special servicer in June 2020 for payment default following sustained performance declines, which were exacerbated by the Coronavirus Disease (COVID-19) pandemic. A loan modification was executed in September 2022, including $5.0 million of new borrower equity to cure the loan. While the loan was reinstated in December 2022, performance has continued to struggle, and the borrower has requested the loan be returned to the special servicer.

The hotel’s performance initially declined in 2017 because of a combination of new hospitality properties delivered to the submarket and the sponsor’s conversion of the hotel to the Dossier boutique brand from the original Westin flag, which was completed in 2018. Despite a rebranding of the hotel, performance did not stabilize prior to the onset of the pandemic, when the hotel was closed for most of the time between March 2020 and October 2021. The property’s restaurant tenant remains closed and is not expected to reopen. For the period ended January 31, 2023, the property reported trailing 12-month (T-12) occupancy, average daily rate, and revenue per available room (RevPAR) figures of 37.8%, $142, and $54, respectively. The RevPAR penetration rate for the T-12 period was 59.6%, indicating the property continues to underperform relative to its competitive set.

According to the September 30, 2022, T-12 financials, the loan reported a net cash flow of -$1.9 million (reflecting a DSCR of -0.51 times (x)), a substantial decline from both the YE2019 and issuance figures of $2.3 million (a DSCR of 0.63x) and $6.2 million (a DSCR of 1.69x), respectively. The most recent appraisal is dated August 2022 and valued the property at $44.9 million, below the December 2021 value of $50.2 million and the issuance value of $83.6 million. DBRS Morningstar’s analysis, which includes a liquidation scenario based on a stress to the most recent appraisal, indicates a loss severity of nearly 40.0%.

While the concentration of office properties is relatively low, it is notable that these loans exhibited weaker performance than the pool as a whole. Given the cautious outlook DBRS Morningstar has on office assets, the analysis for this review included a further stress of these loans to test the durability of the ratings, resulting in a weighted-average expected loss that is nearly three times the pool average expected loss.
