All of your arguments are based on nothing but "what if's", MB rumors and being uninformed.
A+M was being paid for doing all the accounting work for the LT, and also fully staffing WMIH until the merger with NSM was finalized and the transition complete.
Those duties were why they were being paid $500K/qtr, not some baseless MB fantasy about "managing assets".
BTW, I can't believe you even have to ask why there was so much billing for seemingly so little work...they were "milking" the estate, as has been done in virtually every bankruptcy...EVER!
