-- Class E at BBB (low) (sf)
-- Class F at BB (low) (sf)
-- Class G at B (high) (sf)

All trends are Stable.

The rating confirmations reflect the overall stable performance of the transaction since DBRS Morningstar’s last review, with collateral revenue generally in line with the Issuer’s figure since closing in 2018. At issuance, the loan was secured by a portfolio of 22 life-sciences buildings (office and laboratory) and one parking garage totaling 2.4 million square feet. The properties are located across California, Washington, Massachusetts, New York, Pennsylvania, and New Jersey. Since issuance, three properties known as Walnut Street, Trade Centre Avenue, and Bernardo Center Drive have been released. These properties collectively represented 6.7% of the issuance allocated loan amount (ALA), and, based on the release provisions as outlined in the transaction documents, a total release premium of $62.5 million was paid, with proceeds applied pro rata across the bond stack. The pro rata paydown structure will remain in place for releases executed to a cap of 25.0% of the unpaid principal balance on the loan. After the 25.0% threshold is met, the release premium will increase to 110.0% from 105.0% of the ALA and release proceeds will be paid sequentially down the bond stack.

At issuance, the whole-loan proceeds included $725.0 million of senior floating-rate debt, which is held in the subject trust, $140.0 million of senior mezzanine debt, and $95.0 million of junior mezzanine debt. The loans were used to refinance existing debt of $714.6 million, with $216.9 million of equity returned to the sponsor. The sponsor is an affiliate of The Blackstone Group Inc., which acquired the subject in 2016 as part of the acquisition of BioMed Realty Trust, Inc. The loan had an initial two-year term with five one-year extension options, with a final maturity date on May 9, 2025. In May 2021, the borrower exercised its second 12-month extension, extending the maturity until May 9, 2022. The loan is interest only for the fully extended term.

According to the trailing 12-month period (T-12) ended September 30, 2021, net cash flow (NCF) was reported at $57.6 million. While the T-12 NCF is down 10.8% compared with the year-end (YE) 2020 NCF, the September 2021 NCF exceeds the DBRS Morningstar NCF figure of $52.8 million. According to the September 2021 rent roll, the portfolio was 81% occupied, which is a decline from the YE2019 occupancy rate of 92.6%. Given the healthy demand for life-sciences space and the portfolio’s stable historical performance and strong sponsorship for the subject loan, DBRS Morningstar expects the occupancy decline will be short-lived. The 2021 financials are inclusive of income and debt service associated with the Bernardo Center Drive property that was released in January 2022.
