Remember that Alice claim is similar to the employee claims, she has to win first or otherwise she won't get a penny for her attorney fees. If she wins which I think it is unlikely, the underwriters will be kicked out of class 19, which will save us money in case that more than 10B will be returned.
I think that Alice ultimate goal is to open the other Pandora box which is why we may get near zero if it is the case.
Now the only thing I worry about is if escrow will get a decent 5-15B but not hundreds of billions like Alice thinks then she can tie up everything with her litigation for the phantom money.
