The suggestion that COOP's additional $640B in assets is all former WAMU assets is nonsensical since it would mean that JPM retained none of the WMB assets they ""bought"" from the FDIC.
Also as tanja suggests, if former WMI assets/interests controlled by the WMILT were transferred to COOP, what has happened to those returns since they were transferred???
These theories all sound great but unfortunately they, IMO, will likely not materialize.
