This wasn't his personal PNL. He didn't have a contract that specified his cut, as otherwise he would have no need for arbitration. Ergo, this guy has no case and should stop wasting everyone's time.
agree.... if he worked at GS and 'helped' make the money 'and expected' to get the same as before, and sure he may have been stiffed by the 'discretionary bonus' system but hey - if he had not worked out that there is politics involved, someone needs to be a scapegoat and that he ended up on the short end of the stick then it explains why he got shafted. On the other hand - he is simply rolling the dice and looking for a payout which is what one might expect. Does anyone else find it slightly ironic that his mother house burnt down and she should not worry because he will be paid a big bonus. Surely he could a) either have used his financial knowledge to have ensured she was at least insured an hence his bonus would not be needed or b) buy her a house with his previous bonus.
