Based on previous discussions and posts, Fidelity is one of the few brokers, if not only, that accept ComputerShare certificates of CYDY (likely any OTC). There have been periods of times when even they would not accept them.

From my personal experience (thanks to help from FullTilt and smlf), I contacted their restricted trading desk and confirmed they would accept them. They said I could go to a local branch or mail in the certificate. I contacted the local branch and went in the next day. The local branch manager had to contact the corporate risk desk and I was told they would not accept them. I called the restricted trade desk back and was told if I mailed it in they would likely accept the certificate for deposit. Once they received the certificate, the shares were deposited within 24 hours.

I know others have had conversations with the restricted trade desk and received conflicting information. My understanding is this is because CYDY has so many different offerings with some being restricted and unrestricted shares that they have a maximum quota based on their risk allowances and being that they are one of the few (if not only) broker accepting these CYDY certificates that they are likely pushing the risk envelope sometimes......or the person on the other end of the phone sees that one/some of the certificates they are not accepting and just says no to all CYDY certificate deposit inquiries to cover his/her tail.
