That is not true. Bankruptcy cases often use those numbers to help determine the value of a company.
The judge will take into account that the POR has the bondholders receiving 8 cents on the dollar while they are paying 110 cents on the dollar.

The open market has and will continue to be used as a valuable measuring stick in these cases.
