All trends are Stable.

The rating confirmations and Stable trends reflect the overall stable performance of the pool, which has remained in line with expectations since DBRS Morningstar’s last rating action in November 2022. In January 2023, the 800 Chester Pike loan (Prospectus ID#52, previously 0.6% of the pool) was liquidated from the pool with a loss of $1.1 million (loss severity of 13.2%), compared with the DBRS Morningstar estimated loss of $1.4 million. Two additional loans, Millside Plaza (Prospectus ID#35, 0.9% of the current pool) and PA Rite Aid Portfolio (Prospectus ID#65, 0.4% of the current pool), were transferred to special servicing in April 2023 and May 2023, respectively. Both loans were analyzed with elevated probabilities of default (POD) for this review.

DBRS Morningstar’s primary concern continues to be the pool’s high exposure to loans secured by regional mall properties, two of which are being monitored on the servicer’s watchlist. Both The Mall of New Hampshire (Prospectus ID#3, 9.0% of the current pool) and Westfield Trumbull (Prospectus ID#7, 3.7% of the current pool) loans were analyzed with elevated PODs to reflect their current risk profiles and, for Westfield Trumbull, an elevated loan-to-value ratio (LTV) was applied given the recent sale of the property. Seven loans, representing 18.2% of the current pool, are secured by office properties. None of the seven office-backed loans are being monitored on the servicer’s watchlist, and they reported a weighted-average (WA) YE2022 debt service coverage ratio (DSCR) of 1.69 times (x). Given the shift in demand for office space following the Coronavirus Disease (COVID-19) pandemic, DBRS Morningstar anticipates upward pressure on vacancy rates in the broader office market. To account for the possibility of value declines and increased refinancing difficulties, DBRS Morningstar applied stressed LTV ratios to all seven loans.

As of the May 2023 remittance, 80 loans remain in the pool with a trust balance of $1.1 billion, representing a collateral reduction of 21.7% since issuance. Nineteen loans, representing 13.5% of the current pool, are fully defeased. In addition, 14 loans, representing 24.1% of the current pool, are being monitored on the servicer’s watchlist and three loans, representing 1.7% of the current pool, are in special servicing.

The Mall of New Hampshire is the largest loan on the servicer’s watchlist and is secured by 405,723 square feet (sf) of in-line space in an 811,573-sf Class B single-level enclosed regional mall in Manchester, New Hampshire. The mall, which is jointly owned by Simon Property Group and the Canadian Pension Plan Investment Board, is anchored by Macy’s, JCPenney, and Dick’s Sporting Goods—none of which act as collateral for the loan. Because of the business interruptions amid the Coronavirus Disease (COVID-19) pandemic, the loan transferred to special servicing and a cash trap was activated in December 2020. The cash trap remains active as of May 2023 and, according to the May 2023 reserve report, $1.4 million of lockbox receipts have been collected, in addition to $213,000 outstanding in a leasing reserve. The loan returned to the master servicer in May 2021 after a forbearance was executed to defer interest payments from May 2020 through December 2020. According to the September 2022 rent roll, the collateral was 84.8% occupied, an increase from the December 2021 occupancy of 83.0%. The largest collateral tenants include Best Buy (10.4% of the net rentable area (NRA), lease expires January 2024), Old Navy (4.6% of NRA, lease expired January 2022), and Ulta (2.9% of NRA, lease expires May 2025). DBRS Morningstar has inquired about the status of Old Navy’s lease and is awaiting response; however, according to the mall’s website, the tenant is still in occupancy. According to YE2022 tenant sales report, the mall reported in-line sales (excluding Apple) of $437 per square foot (psf), which is up from the in-line sale of $396 psf as of August 2021. As of the trailing nine-month financials ended September 30, 2022, the loan reported an annualized net cash flow of $11.6 million, equating to a DSCR of 1.85x compared with the DBRS Morningstar DSCR of 2.30x. Although the loan’s in-place coverage remains healthy, cash flow has not met DBRS Morningstar’s expectations. In the analysis for this loan, DBRS Morningstar applied a stressed POD, resulting in an expected loss more than 50.0% greater than the pool’s WA expected loss.

Westfield Trumbull is secured by 462,869 sf of a 1.1 million-sf regional mall in Trumbull, Connecticut. The collateral includes the Macy’s (18.8% of NRA, lease expired April 2023) anchor pad and all in-line space. Additional anchors, JCPenney, Target, and one pad that was previously occupied by Lord & Taylor but is now vacant, do not act as collateral for the loan. DBRS Morningstar inquired about the status of Macy’s lease but has not been provided an update from the servicer; however, the tenant is reportedly open according to the mall’s website. The loan was added to the watchlist in March 2022 for a declining DSCR and a cash sweep initiation. DSCR was reported at 1.39x with an occupancy rate of 93.2% as of September 2022, in line with the YE2021 DSCR of 1.36x and occupancy rate of 96.6% but well below the DBRS Morningstar DSCR of 2.47x. A lockbox was established after the loan’s debt yield fell below 7.5% and, according to servicer commentary, approximately $775,000 had been trapped as of January 2023. According to various news articles, the subject and another mall owned by Unibail-Rodamco-Westfield (URW) were sold in December 2022 to Mason Asset Management and Namdar Realty Group for a combined sales price of $196.0 million. As part of that transaction, the subject debt was assumed. This loan was previously been flagged by DBRS Morningstar as a loan of concern because of its exposure to Lord & Taylor (which has since closed) JCPenney, weakened sales, declining cash flow performance, and URW’s April 2022 announcement that it would sell all of its U.S. malls by 2024. Given this, DBRS Morningstar expects that the individual sale price for the subject property represents a significant discount from the issuance appraised value. To reflect the elevated refinance risk ahead of the loan’s March 2025 maturity, DBRS Morningstar analyzed this loan with an elevated POD and increased the loan’s LTV to 100.0%, resulting in an expected loss more than 250.0% greater than the pool’s WA expected loss.
