You're oversimplifying this. If someone owes you $1B and they owe me $2B, and they've got an asset worth $500M, I can't just pledge $2B of bad debt to buy the asset. The only fair way is to sell it for $500M in actual cash. Then it gets divied up accordingly.

Isn't it telling that the same judge said it was done improperly? Trustees have an obligation to follow standard practices which maximize cash flow or at least don't give the appearance of impropriety.
