JPM, nor the FDIC owes us any more money for WMB and it's assets...IF, and that's an enormous IF, distributions are made by JPM to Equity holders it will be the accumulated cash from any remaining WMI/WMIIC's retained Snr, and/or Sub residual interests in WAMU MBS's.
When bankruptcy is filed cash returns from any such interests are halted as per the Law and/or Trust Agreements, as such if JPM is the current servicer of such MBS interests they would be accumulating these payments in specific accounts on behalf of the ??Estate/WMILT??.
If true, once the bankruptcy cases are closed that should trigger the distribution of those funds from these accounts by JPM or the relevant Trustee to ??Equity/WMILT??.
