What we do know, is the company has gained control of several million certified shares that have been converted to PDRs. Those shares are supposed to be locked down like gold and represent the backing of the PDR (reciept). If the company chose to sell those shares, the PDRs would no longer be backed by them and then all hell would break lose.
Bottom line is one stock based PDR is equal to 10,000 shares. They can not have more PDRs then the OS/10,000 which is just over 500,000 pdrs. I wonder how many stock pdrs exist on the exchange right now. Now the company does know that.
