Question for the group. Were the most recent options given to management free and effective now for hitting the milestones or are they timebound, ie. 33% per year they can exercise. For some reason I thought they were free and clear once they hit the milestones which right now if that is the case I do not like. Just wondering. I will try and track it down a bit later when I have more time but if someone knows this answer I appreciate. thx.
