I suspect the "R" needs to be final. The FDIC-R does not want to go through finalization multiple times. Regardless of what they say, they took WMI assets in case they needed the money for claims. The WMI assets very well may be the first assets returned to WMILT, before #3 above. The "R" needs to be finalized, not necessarily the WMI BK.
Of course JPM is waiting on their payment from "R" - $645MM before they will do anything. I'm sure the terms for even these recent actions were all ironed-out a long time ago then JPM had a strong hand, making the deal. They even have the $645MM that must be paid within 10 days of the DB settlement. We are closer than we have ever been ;)
