Context
RSU grants are common compensation/retention tools for directors and do not represent an immediate market buy or sell. If and when the RSUs vest, they typically convert to common shares (and may be subject to tax withholding or sale if required), at which point a separate filing may reflect the issuance or any subsequent sale.
