The Federal Deposit Insurance Corporation (FDIC) may assume deposits of banks or allow other banks to assume them. The largest banks to be acquired have been the presumed Merrill Lynch acquisition by Bank of America, the Bear Stearns and Washington Mutual acquisitions by JPMorgan Chase, and the Countrywide Financial acquisition also by Bank of America. IndyMac Bank was also a large bank that was changed into a bridge bank by the FDIC, after its failure, until the funds can be disposed of. In addition, the investment bank Lehman Brothers has filed for Chapter 11 bankruptcy protection.
