FDIC is the receiver for WMB. The WMI funds under dispute are those they have presented to the court as a 'deposit'. JPM has argued those funds (4B$) 'MAY' be a deposit BUT they also presented facts which 'MAY' show this money as nothing but a shell game by WMI in the weaning days of this bank. The FDIC position is that they took WMB and all deposits as assets and any claim to those deposits can only be made through the receiver. JPM bought the assets from FDIC and to questionable understanding has limited liability for those funds to the debtor(WMI). FDIC reinforced their position as the receiver and in their judgement the money in dispute represents anything other than a WMI deposit -- whether it's proven to be 'empty funds' or real funds JPM/FDIC allege that the funds may be part of a shell game, may represent capital investment(monies raised by WMI just before the seizure were acknowledged by many as being for the purpose of bolstering WMB), or may have been a loan to WMB and any of those results would stand in the way of WMI getting them back. These things can only be determined in what they call a real trial or discovery. So the FDIC and obviously JPM do not view these funds as a deposit evidenced by manipulations by WMI/WMB in the description or position of these funds in the days leading up to the seizure. Now at least three major players are saying they have rights or a say in the disposition of these funds before WMI does - JPM/FDIC/WMB Bondholders
