Enron's shares have been suspended from trading on the New York stock exchange.
The company is expected to detail the sale of its core trading business later today.
Enron lost credibility on Wall Street after it was learned that top company officials engaged in improper accounting practices.
The company has already filed for chapter 11 bankruptcy - which allows a company to continue trading while seeking protection from its creditors.
The US Justice Department launched a criminal investigation into Enron and particularly into how many employees lost their life's savings when it filed for bankruptcy protection. Its collapse is the biggest corporate failure in US history.
The shares, which were once worth over $70, stood at just 67 cents when trading was stopped.
