The FDIC got their back scratched because JP Morgan got what they wanted at an unbelievable price. With the new accounting rules though they had to mark the value of acquired assets immediately. They found a buyer of those real quick and at an appealing price still or else they wouldn’t have done it.
Under, I don’t have any media or print confirmation on that and according to the company memo that went out after the deal, they are still using the WaMu brand name temporarily. You likely got some fluke check but I doubt you’ll be able to tie it to any proof of an early takeover. That would get some dirty dealers in a lot of trouble.
