All trends are Stable.

The rating confirmations and Stable trends reflect the overall stable performance of the transaction, which remains in line with DBRS Morningstar’s expectations.

The $3.0 billion mortgage loan is secured by the borrower’s fee-simple interest in One Vanderbilt, a 1.6 million-square-foot (sf) ultra-luxury Class A office high rise in Midtown Manhattan, New York. In addition to more than 1.5 million sf of luxury office space, the property includes a 67,000-sf observation deck (the Summit) and approximately 32,000 sf of high-end commercial space and is directly adjacent to Grand Central Terminal. The property was developed by the sponsor, SL Green Realty Corp., which owns 71.0% of the property. The remaining 29.0% is owned by The National Pension Service of Korea, one of the largest pension funds in the world, and Hines Interests Limited Partnership, one of the largest privately held real estate investors. The fixed-rate loan is interest-only (IO) throughout its 10-year loan term and matures in July 2031.

According to the December 2022 rent roll, the property was 96.7% occupied, in line with previous years. The property benefits from long-term, investment-grade tenancy, including the two largest tenants, TD Bank and Securities (20.8% of net rentable area (NRA); expiring July 2041) and Carlyle Investment Management (11.8% of NRA; expiring September 2041), which, combined, account for approximately 65.0% of annual rental income. According to Reis, Class A office properties within the Grand Central submarket reported vacancy and effective rental rates of 12.5% and $81.31 per square foot (psf), respectively. The property is outperforming the submarket and reported vacancy and effective rental rates of 3.3% and $91.51 psf, respectively. Additionally, the property benefits from minimal rollover risk, with only 5.2% of NRA expected to roll during the loan term.

The annualized net cash flow (NCF) for the period ended September 30, 2022, was $26.5 million, compared with a loss of $27.5 million at YE2021 and the DBRS Morningstar derived NCF of $175.3 million. DBRS Morningstar accounted for the collateral’s recent delivery in 2021 and the majority of tenants still in free rent and/or buildout phases at issuance. Therefore, the cash flow is not reflective of stabilized property performance.

DBRS Morningstar expects the collateral to continue to improve toward stabilization levels given the property benefits from strong sponsorship, luxury amenities, a prime location, and long-term, investment-grade tenancy.
