Yeah...billions and billions of shares dumped. And not one dime recovered. Do you find that a bit unusual in this day of sophisticated forensic methods? Just asking.
Any move to de-register the stock will be based upon the company's failure to submit financial filings. However, it was the initial bankruptcy trustee who failed to submit the last filing. All I care about, in terms of that filing, are the number of shareholders then reported (which was one billion more than the company claimed).
