I will share anything I know with you...having said that, the rub in your question is akin to Clinton's famous definition of "is" :)
The shareholders always think the assets are greater than liabilities based on publicly available reports. Unfortunately, the downward spiral once a company gets close to BK changes last quarters reports tremendously. So, when you ask the question, the real Q is regarding assets/liabilities as the court finds them. Then the answer is no. I was following, but not in court, Pilgrims Pride. A huge winner. Management stated they wanted to preserve shareholders and they were true to their word. In Ambac, shareholders were sure they assets were there, but the court disagreed...shareholders are still holding on, but to very reduced share value. In Wamu, we're going back for a second round this month, to try and gain more value via lawsuits.
Don't know if this helps or not, but I've seen both sides.
