MBS sponsored, sold via securitizations prior to...
...WMB seizure are OWNED BY THE INVESTORS THAT BOUGHT THE MBS SECURITIES.
...WMB, and subs, retained interests in such, depending on asset quality (investment grade, recorded as asset, less than recorded as retained interest and reported as trading assets) WERE ASSETS OF WMB that were 'seized and sold.
...the proof was to be the Deutsche Bank CA Probate Court notice to the 'mom and pops (i.e., WMI escrows).
...nope, didn't happen.
...WMI/WMIIC had "NOTHING TO DO WITH" such MBS; neither were BANKS.
...and 'Safe Harbor is re: IN PROCESS MBS that quality for protection and sale treatment (FASB); THERE WERE NONE AT SEIZURE.
...just an FYI, such "protection" is for the BUYERS OF THE MBS SECURITIES (i.e., not the former shareholders, of the former holding company, that owned the abandoned former bank after it was seized and sold).
