The CUSIP changed from dummy CUSIP 794CNT980 to the new CUSIP 794016204.
It looks like this happened about a month ago (06/15/18) according to my TD Ameritrade account, but I just now noticed.
Per the email response MightyBull received from TD Ameritrade a couple months ago:
Thank you for the e-mail. At this time the new CUSIP 794016204 will not be made DTC (Depository Trust Company) eligible. Therefore, the CONTRA CUSIP 794CNT980 has been created to receive the new entitlement. Upon receipt of the new shares, the shares will be exited. There is no ETA on this deposit at this time, thank you for your patience in this matter.
Since this transition from the dummy CUSIP to the new CUSIP actually did go through, maybe this means they truly are taking concrete steps towards becoming DTC eligible and being relisted?
