In the Opinion by Judge Walrath it states that at least 23 entities make up the WMI Noteholder's Group - and it is not clear if the WMI Noteholder's Group are being represented also in the Committee of Unsecured Creditors or maybe these are the secured bondholders who want a say in the proceedings.
Here is the link to the Opinion by Judge Walrath - I may have missed something -
I am looking back at the old filings and I found this one dated October 9, 2008 that lists the creditors - David Bonderman is listed on page 250 - I cannot find TPG listed except for the following names which may or may not be subsidiaries.
Also most interestingly I found a court filing dated Nov 17, 2008 for TPG Olympic Investment that holds the 230 million of WMI common shares and it listed holding several WMI preferred shares as well. I am going to check tomorrow if these preferred shares correspond with the 3.9 billion listed on the MOR.
