My understanding is when the judge signs off (which could take a while) the shares become worthless. That's probably is the worse case scenario. Because of the heavy volume this week there maybe something else going on, like a buy-out might be in the works. In that case, I think our shares would still have value or a new company may be formed in that case our shares would get transferred and for every x number of shares we have we would get x number of shares of the new company.
Remember this ch. 11 had nothing to do with the business itself, just a lawsuit by the two former executives and UNXL could simply not pay the settlement therefore they had to file ch. 11. The company still has technology, patents and other assets that have value and has been recognized by other more established companies. This is the positive side of this situation. So we will see only time will tell now, just hold onto to your shares and see what happens I guess.
