I will assume if you are not registered in Computershare as owning the shares bought OTC you would be $hit out of luck,,,,,thats my guess,,,,the trading is sort of like dealing in crypto shares imo.

As DM explained at the AGM, Zenith shares are trading on the OTC.  And the CUSIP number on the trade confirmations matches Zenith's.  Sooooooo what do you think is trading if not Zenith shares?
