Enron was an energy trading company that grew tremendously in the 1990s to become the 7th largest company in America by 2001 with assets of $65.5 billion. However, in late 2001 it filed for bankruptcy. A journalist had questioned Enron's accounting in early 2001 based on signs like increasing debt, declining cash flows and poor returns. An analysis of Enron's 2000 annual report also revealed worrying financial indicators such as low profit margins, returns and high gearing that suggested problems but were overlooked.
