Sullivan & Cromwell was not aware of the ongoing fraud at FTX while the law firm represented the cryptocurrency exchange in 20 matters before becoming its debtor counsel, a court-appointed examiner stated in a report Thursday.

However, examiner Robert Cleary of Patterson Belknap Webb & Tyler asked the U.S. Bankruptcy Court for the District of Delaware to conduct two additional investigations into Sullivan & Cromwell’s prepetition work for FTX, which occurred in the 16 months before the company’s November 2022 bankruptcy filing.
