Context
RSU grants are a common form of director compensation and represent a promise to deliver shares if vesting conditions are met; they do not involve an immediate cash purchase by the insider. Because RSUs can be forfeited before vesting, they are different from open-market purchases and typically do not, by themselves, signal an immediate insider market conviction.
