This is news to me. I'll try to contact the BNY Mellon Trustee - John Guiliano - if I can find his phone number again.
UPDATE: Here is the name and address of the Trustee who filed Claims on behalf of the CTS/SUB NOTES Holders:
John M. Guiliano · The Bank of New York Mellon GLOBAL CORPORATE TRUST, 101 Barclay Street, 8 West, New York, NY 10286 · Tel 212.815.5441 · Fax 732.667.9239 · john.guiliano@bnymellon.com
