Context RSUs are a form of equity compensation that convert into company shares upon settlement; because these RSUs vested on the grant date, they represent immediate compensation rather than an open-market purchase. Such director awards are commonly part of regular compensation and do not by themselves indicate an insider view on the company's stock price.
