It doesn't work that way. No U.S. court would uphold such a transaction, even if it weren't specifically prohibited in the loan documents, which I guarantee it is. See my post #50. The Fortress Investments folks are not lightweights. You can be sure they bought the loans at a significant discount from BofA, and they already know exactly what their profit will be -- the difference between face value and what they paid for it. Banks don't like to have bad loans on their books for regulatory reasons, and for shareholder image reasons (non-performing or otherwise imparied loans will be shown separately on the bank's publicly available financial statements), so they will often sell them for somewhat less that they could ultimately realize if they held onto them.
I think that Sony (which co-owns the rights under a joint venture with Jackson) has the right to match any offer.
