All trends are Stable.

The rating confirmations reflect the stable performance of the transaction, which has remained consistent with DBRS Morningstar’s expectations. At issuance, the transaction comprised 33 fixed-rate loans secured by 57 commercial and multifamily properties with a trust balance of $810.7 million. As of the July 2022 remittance report, all loans remain in the pool with an outstanding trust balance of $801.0 million, representing a nominal collateral reduction of 1.2% since issuance.

There are three loans—1000 Wilshire (Prospectus ID#2, 8.1% of the pool balance), Aliso Creek Apartments (Prospectus ID#3, 7.9% of the pool balance), and Marina Heights State Farm (Prospectus ID#11, 3.4% of the pool balance)—that were shadow-rated investment grade by DBRS Morningstar at issuance. With this review, DBRS Morningstar confirmed that the performance of these loans remains consistent with investment-grade loan characteristics.

As of the July 2022 remittance, no loans have been defeased, nor are there any loans in special servicing. There are six loans on the servicer’s watchlist, representing 11.0% of the pool balance. The servicer is monitoring these loans for a variety of reasons, including low debt service coverage ratio (DSCR), concerns with occupancy, and/or tenant rollover risk.

DBRS Morningstar has been closely monitoring the largest loan in the pool, GSK North American HQ (Prospectus ID#1, 9.4% of the pool balance), following the decision by the property’s single tenant, GlaxoSmithKline plc (GSK), to vacate its space in Q1 2022, as announced in 2021. The subject loan is secured by a Class A office complex in Philadelphia’s Navy Yard submarket. The property was built-to-suit for GSK at a cost of $80.0 million in 2013, when GSK executed a 15-year lease through September 2028 with no termination options.

Although the subject is now physically vacant, GSK will continue to honor its rental payments through the remainder of the lease term. According to the servicer, Jones Lang LaSalle has been engaged to market the space for sublease. The loan was structured with a cash flow sweep that was to be triggered if GSK vacated or went dark in at least 90% of its space, excluding subleases signed by GSK. As of the July 2022 reporting, the servicer noted $1.7 million being held in the cash management account but no funds held in tenant reserves. Office properties in the South Philadelphia submarket have historically reported strong market fundamentals, supported by the Q1 2022 vacancy rate of 1.1% as reported by Reis.

According to an article published by The Philadelphia Inquirer on June 28, 2022, a $6.0 billion investment plan to revitalize and redevelop the Navy Yard over the next 20 years was announced, with the hope of creating a new neighborhood in the city. This plan is estimated to bring 12,000 new jobs to the Navy Yard, as well as 8.9 million square feet (sf) of new residential, commercial, retail, and mixed-use space. The developers, Mosaic Development Partners and Ensemble Real Estate Investments, plan to build 4,000 residential units as part of the redevelopment.

Based on the annualized Q1 2022 financials, the loan reported a DSCR of 2.40 times (x), compared with the YE2021 and YE2020 DSCR of 2.33x. The historically strong DSCR figures suggest that some meaningful excess cash can be trapped between the trigger event and loan maturity in June 2023. According to the appraisal at issuance, the dark value of the property was reported at $91.8 million, which is in excess of the whole-loan amount of $85.2 million. Although the loan’s refinance risk has significantly increased following the departure of GSK given the upcoming loan maturity in June 2023, mitigating factors include historically strong submarket and property performance in addition to the redevelopment plans discussed above and the sponsor’s commitment to the property. Korea Investment Management, an investment firm owned by Korea Investment Holdings Co., Ltd. (a financial services firm in South Korea), is the loan sponsor and has been working with Coretrust Capital Partners, LLC, which serves as a domestic asset manager in the United States. At issuance, the sponsor contributed $45.9 million of equity to purchase the property.
