LG, you still have not provided a logical explanation to "why" issue separate escrow markers 19 and 22 if 75/25 split to the end. You yourself stated that all the old prospectus for preferred and commons were cancelled and void...
So why set up class 19 and 22 markers distinguishing different classes for preferred and commons who released?
If the objective is to nullify all the old prospectus and split all returning assets 75/25 to the end, then the logical action would be to issue one class of escrow markers and split the markers 75/25 to the releasing old preferred and commons. So that one class of marker guarantees that the old prospectus of preferred and commons were nullified and the returning assets dont care if you are old preferred or commons - one class of marker would guarantee 75/25 split for everything to the end.
I highly doubt the estate issued separate classes of class 19 and 22 just because they can... there is a reason why they maintained separate identity for releasing preferred and common classes. If there is no distinguishing need, and all they want is 75/25 split to the end, then they would have just issued one class of escrow and split the markers 75/25...just like they did for the initial issue of WMIH common stock.
