"Ross, Marks, Watsa and Wilder each are represented on the BOD. No doubt, if there ever was any, who the new owners of the company will be."
The only way they have any claim to a new company is if they own collateralized debt. And based on all know information, Ross and Marks do not have exposure to collateralized debt. They do have 650M and 750M equity positions, respectively. Watsa and Wilder are the only two who have exposure to collateralized debt (~$400M FairFax/Term Loan for Watsa, and ~$47M Term Loan for Wilder).
So, Ross and Marks are entitled to no more a part of a new company as the shareholders of the same common stock that they own, are.
