You can bring the preferred share certificates to your broker, like any other share certificate. Obviously, they are restricted from sale until September, some brokers may require you to hold until then while others will monitor the restriction for you. Check with your broker to see how they will handle it. Physical certificates are a lot more common than you think. I remember back when it was common for companies to provide the when you purchased shares. Things moved a lot slower in those days.

Btw, are you from NL?
