Context RSUs are a form of equity compensation that convert to common shares upon vesting (here, generally one share per RSU). Because this is a compensation grant to a non-employee director, it reflects routine board pay rather than an open-market purchase or sale; it does not, by itself, indicate a trading decision by the insider.
