Sounds very interesting. I am still holding bonds and am watching this. Today, I sent an email to the trustee expressing my interest in participating.
However, the big players would be better suited to finance this.
I suggested to the trustee to
a) contact the Depository Trust & Clearing Corporation (DTCC), which could contact all people still holding the bonds (they can do that for corporate actions like splits/dividends etc.),
b) contact the plaintiffs in the ATP bonds securities class action, Court of Appeals Docket #: 1531094: The Firefighters Pension & Relief Fund; or in general members of the class,
c) contact the Bank of New York Mellon Trust Company, N. A. as trustee and collateral agent for the bonds.
The DIP Lenders should be interested in investing some money as well to recoup their DIP claim.
