Context
RSU grants are a routine form of executive compensation and do not reflect an immediate purchase or sale of stock. Because these RSUs are performance‑based and will vest over time (subject to continued service), they represent a future potential issuance of common shares rather than an immediate change in share ownership or market activity.
