WASHINGTON AP – The federal seizure of struggling Florida thrift BankUnited FSB is expected to cost the Federal Deposit Insurance Corp. $4.9 billion, representing the second-largest hit to the FDIC’s insurance fund since the financial crisis began felling banks last year.

The costliest was last year’s seizure of California lender IndyMac Bank, on which the bank insurance fund is estimated to have lost $10.7 billion.
