I recently questioned TDA about a different worthless turd, MFNXQ, that's been dormant in my account for 8-10 years. Asked about 'unmarketable securities' and got this response......
Thank you for contacting us regarding removing a security from your account. To remove this security with no market indication from your account, the following option is available:
You may request to sell the entire position to TD AMERITRADE for a sum totaling one dollar. A commission of no more than the current Web rate will be charged for the transaction. This transaction will generate a trade confirmation and will be irreversible.
You may contact Client Services by phone at 1-888-871-9007 to place your request.
Sincerely,
Rachael Peacock
