Enron filed for bankruptcy in the Southern District of New York in late 2001 and selected Weil, Gotshal & Manges as its bankruptcy counsel. It ended its bankruptcy during November 2004, pursuant to a court-approved plan of reorganization, after one of the most complex bankruptcy cases in U.S. history. A new board of directors changed the name of Enron to Enron Creditors Recovery Corp., and emphasized reorganizing and liquidating certain operations and assets of the pre-bankruptcy Enron. On September 7, 2006, Enron sold Prisma Energy International Inc., its last remaining business, to Ashmore Energy International Ltd. (now AEI)
