Dmdmd2020, thank you very much for your first-class due diligence second to no one! This is about as good as it gets short of LARGE GREEN showing up in our accounts instead of this message board.
Between you and the valuable information that CBA09 showed us, we are totally GOLDEN. Curious, what hotmeat has to say about this. No way any serious person could NOT conclude with this indirect and circumstantial proof that we are more-than-likely GOLDEN.
The real issue is whether WAMU securitizations were held by WMB or shielded by WMI subsidiaries. If they were held by WMB, they were seized and sold as apparently the $26B in Available for Sale Securities were ($18B in MBS's). To date we are yet to see any tangible proof that WMI kept beneficial interests in MBS's or actual MBS assets off WMB's books. If there are we could be in good shape but to date, I have not seen any proof of such.
