On September 25, 2008, JPMorgan Chase bought most of the banking operations of Washington Mutual from the receivership of the Federal Deposit Insurance Corporation. That night, the Office of Thrift Supervision, in what was by far the largest bank failure in American history, had seized Washington Mutual Bank and placed it into receivership. The FDIC sold the bank's assets, secured debt obligations, and deposits to JPMorgan Chase & Co for $1.836 billion, which re-opened the bank the following day. As a result of the takeover, Washington Mutual shareholders lost all their equity.
