Federal regulators have reached a settlement with the owners of defunct Superior Bank. In a statement, the Federal Deposit Insurance Corp. and the Office of Thrift Supervision said Superior’s holding company would pay $460 million to settle "all matters" related to the Illinois-based thrift’s July failure. While admitting no liability, the holding company has already made a $100 million payment. The remainder is slated to be paid off interest free over the next 15 years.
