The FDIC sold Signature Bank’s $18.5 billion loan portfolio to large private equity and investing firms, including 201 capital-call loans from Starwood Capital Group, Carlyle Group, Blackstone, Thoma Bravo, and Brookfield Asset Management.

The sale was initiated after state authorities closed the bank in March due to regional bank problems.

The July 25 offer is for FDIC-insured depository institutions, and the loans consist of subscription credit facilities to private equity funds.
