those are restricted stock awards probably given as a year-end bonus...it has no bearing on the open shares available to the public. They are not sales they are distributions...speaking of insider trade there was a lady director Dr Su who purchased $200K of regular shares about two months ago. There may have been others. Havent been looking....its bad news when shares are being sold by insiders...there are a few but low amounts probably sold to pay a mortgage....so not to worry.
