Well it is true that "The Plan", 2nd plan that is, is to cancel all the existing common stock and restart new ones. After reading this plan carefully it does confirm that common shares (they call interest - "Class 9") will get cancelled and furthermore the holders can not vote against this.
So the bottom line is all the other DIP's get to vote on the plan, and if and only if they vote for it will this plan get approved. Judge Shannon will make his final decision based on this and the current financial status of Quiksilver at this time.
With that being said, the only way the common stocks will not get cancelled is if the DIP's vote against this plan, a new one is established, and the companies financials improve dramatically by the time of the next court date. Will the plan go thru the end of January or will this get dragged out until Quiksilver's financials increase dramatically. Of course if some merger happens in the meantime, however that possibility seems to have come and gone.
