There is no proof anywhere of the 86B. I believe in it but all we have is a letter from Dr. A and the fact that THJMW would not allow the real amount to be discussed during the BK hearings.
Clearly, there is something out there. AZ and others have tracked financial instruments and have given ideas of what is possible.
The following is only my opinion:
I believe that the FDIC is waiting for something to happen before closing the receivership. I believe that what they are waiting for is the purchase of the outstanding loans that were seized. If I understand correctly, JPM was given the job of handling those loans but was not given the loans.
My personal hope and expectation is that WMIH/COOP or some layer of that corporate structure will purchase those loans. This cannot happen until the other assets are 'sorted' if for no other reason than WMIH/COOP does not qualify to buy them yet. That is to say they don't have a large enough balance sheet to back them.
Patiently waiting, hoping, and expecting great things to happen.
