MaPi, Merry Christmas to you and EVERYONE here!
MaPi, hotmeat has explained this very well in a simple post. Do not be distracted by other opinions not backed up in fact.
The key to understanding is to know that while there are certain assets that are protected from Creditors via Safe Harbor, thus cannot be discussed or included in this active bankruptcy case, the actual Delaware bankruptcy rules processes control the last link in the title to prove ownership of ALL FORMER WaMu ASSETS!
Again, hotmeat did a good job on the following:
Before Bankruptcy: Trusts--->$CASH$--->WMI/WMIIC
Bankruptcy: Trusts---XXXX---WMI--->Debtors/DIP
Effective Date: Debtors/DIP--->Successor in Interest--->WMILT
Closure of Bankruptcy/Piers Debt Paid: Trusts--->$CASH$--->WMILT--->Equity Interests (75%/25%)
