Sam Bankman-Fried’s failed FTX business empire misused customer funds and lacked trustworthy financial statements or any real internal controls, according to the new boss of the collapsed $32 billion crypto exchange.

John Ray III, a veteran insolvency professional who oversaw the liquidation of Enron, said in a US court filing on Thursday that FTX was the worst case of corporate failure that he had seen in his more than 40-year career.

“Never in my career have I seen such a complete failure of corporate controls and such a complete absence of trustworthy financial information as occurred here,” he wrote.
