The Office of Thrift Supervision on Thursday closed BankUnited of Coral Gables and appointed the Federal Deposit Insurance Corporation as receiver. BankUnited was "critically undercapitalized and in an unsafe condition to conduct business," the OTS said in a statement. The bank reported losses of $1.2 billion in 2008. BankUnited had $8.7 billion in deposits and 85 branches, including 23 in Broward County and 16 in Palm Beach County.
