PricewaterhouseCoopers LLP was ordered to pay the Federal Deposit Insurance Corp. more than $625 million for negligence in the audit of Colonial BancGroup Inc., an Alabama bank holding company that failed during the financial crisis. The firm didn’t design its audits to detect fraud or gather enough evidence of its funding to sign reports.
