Context

• RSUs convert to actual shares when they vest; derivative awards here are structured to vest in tranches and represent rights to future shares subject to service conditions. These grants are routine compensation for executives and do not represent an open-market buy or sale. They do not necessarily indicate the insider's view of the stock; they reflect pay and retention arrangements.
