On the authorized shares, if they use them to pay for drilling or whatever, restricted shares wouldn't hurt us but otherwise I think there will be a date...and before that date they can't be sold. They're also usually issued at a future value, so they wouldn't be sold until the stock was worth more than it is now. For example, they would be issued at a face value of a dime and could be held until they were worth more.
As Larry said, if SIOR does well, it could make the dilution not even noticeable.
I'm obviously no expert, but that's my understanding. If someone can correct me or add to that, please do.
