Not sure. I think if they have taken shares as payment there would be form 4. BUT, that might only apply to Tim because he is over the 10% ownership threshold. If little ole me has millions of shares, I am sure they all do as well. They can buy whenever they want as long as they don’t go over a certain percentage of ownership. I think it’s 5% for you and I, and 10% for insiders. Then you have reporting rules. I may be wrong on that, but’s that’s how I remember it.
They will also have restrictions. I get them at my work. So many days before and after there is to be bigger news, we all get a notice that company shares are not to be bought or sold by the employees.
