At the end of 2001, it was revealed that its reported financial condition was sustained substantially by an institutionalized, systematic, and creatively planned accounting fraud, known since as the Enron scandal. Enron has since become a well-known example of willful corporate fraud and corruption. The scandal also brought into question the accounting practices and activities of many corporations in the United States and was a factor in the creation of the Sarbanes–Oxley Act of 2002. The scandal also affected the greater business world by causing the dissolution of the Arthur Andersen accounting company.[2]
Enron filed for bankruptcy protection in the Southern District of New York during 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.[3] On September 7, 2006, Enron sold Prisma Energy International Inc., its last remaining business, to Ashmore Energy International Ltd.
Enron's predecessor was the Northern Natural Gas Company, which was formed during 1932, in Omaha, Nebraska. It was reorganized during 1979 as the main subsidiary of a holding company, InterNorth which was a diversified energy and energy related products company.
