(Bloomberg) -- Investors snapped up $1.2 billion of bonds linked to a San Francisco office tower that makes up much of Donald Trump’s fortune.

The AAA slice of the commercial mortgage-backed security sold Friday with a discount margin, or risk premium, of 125 basis points over one-month Libor -- roughly in line with other recent office-tower deals.

The bonds are being used to refinance a loan on the 555 California Street property in a deal that gives joint owners Vornado Realty Trust and Trump a $617 million payout.

The complex, among the tallest buildings in San Francisco, is one of two Trump-linked office towers that Vornado is refinancing. The other is in New York. While Vornado majority owns them, Trump’s 30% stake is the most valuable part of his portfolio, making up about one-third of his $2.3 billion fortune, according to the Bloomberg Billionaires Index.

The refinancing -- and cash windfall for Vornado and Trump -- comes months after several banks tied to the former president said they would no longer work with him after the deadly U.S. Capitol riot in January.
