There was never a public disclosure as to the holdings of each Ex-employee Claimant. It is possible that they might own more preferreds and commons which they bought in the open market between September 25, 2008 (seizure of WMB) to March 19, 2012 (Effective Date).
IMO...I believe that the Ex-employee Claimants know the exact value of recoveries to WMI Escrow Markers and they are fighting hard to get the right to release their Class 19 and Class 22 claims (obviously they haven’t released their shares because they are still involved in pending lawsuits).
