Thanks for the link. I took a look at the bankruptcy filings. There was a "Notice of Filing of Valuation of Assets" filed on April 19, 2005 which disclosed that the assets in the liquidating totaled $39.7 million. It is hard to imagine that there will be anything left for the shareholders of Enivid, as the company is now called.
I don't know if they have any plans for the shell. I suspect that they have not issued any additional shares since September 20, 2002, so the stock (trading at $.025 today) is currently being valued at approximately $644,000.
The Enron shares are still trading and I would be willing to guarantee that those shares have no value. The shares of United Airlines and Kmart continued to trade until the day that they were worthless.
