I think that if they can somehow find that the debt holders were in cahoots with management to engage in some sort of impropriety, that equity could walk away with the entire company. I don't see how there wasn't impropriety or even fraud, considering they were discussing the reorganization process and bankruptcy in the SAME MONTH that they issued over $20M of new equity.
If I were the company, I would be engaging in some serious settlement talks right about now with equity.
