Context

• RSU grants are a form of compensation, not an open-market purchase or sale; they become shares only if and when they vest. Such awards compensate and retain executives and do not by themselves indicate an insider view of near-term company performance. Taxes and net-share settlement rules may apply when RSUs vest (not detailed in this filing).
