In my judgement,all those stock sales by directors are the result of stock options. According to Yahoo, the last time anyone actually bought stock, going back to September 11, 2008, was D. Hanif who bought 10,000 shares and James O'Donovan 35,000 shares on March 10, 2009. They each paid $8.52 for the shares. So, I can only imagine that the directors must sell those shares or lose the right to do so.
