RE:Amerisur
My PDQ shares are at Interactive Brokers, where I have AIM trading permission, so if that's where the AMER shares go, I have no problem.
You might be given shares of ASUXF - the American Pink Sheet version of AMER - and be able to trade it that way.
One thing's for sure, which is that Amerisur's price is going to take a hit when all the PDQ selling comes in. Maybe not much of a hit, but 5-10%, I think.
