>>you transfer money from your account to a whole new account <<
This is what you and Wayne are missing. There is no transfer of money back the Lehman. LBHI paid cash for a claim. All Lehman receives back is a claim against the Lehman estate. A claim against itself.
Now explain to me how they would monetize that claim? All the cash they have must go to creditors. Even if they paid themselves a distribution on the claim (they can't because the claim is now cancelled), but saying they could it would be dollars going out the estate and dollars coming back in. It is a wash.
