FTX's vast web of entities had a total of around $1.24 billion in cash balances as of Nov.
The filing was penned by Alvarez & Marsal North America, which is advising FTX on restructuring efforts after the exchange filed for bankruptcy protection earlier this month.
Edgar Mosley, managing director at Alvarez & Marsal North America, said FTX and his team managed to trace "substantially higher cash balances" than they had initially been able to identify by Nov.
A separate filing on Saturday said the company owed $3.1 billion to its largest 50 unsecured creditors.
