Dell Financial Corp, a large US bank, has been a major target of US regulators and US politicians in the wake of the financial meltdown of 2008.
In April, the Federal Reserve announced a plan to close Dell’s US operations by September 2020.
The bank said it had “significant operational risks” and that it had incurred losses that exceeded $1bn.
The US Department of Justice (DoJ) said in August it was considering criminal charges against Dell, which had $8bn of debt outstanding at the end of February.
Dell said the DOJ had not contacted it for comment.
“The Department of the Treasury is not involved in this matter,” Dell spokesman Andrew Smith said.
The Justice Department said in a statement that the department was looking into the bank’s “management of its finances, including its ability to repay its debts.”
