Context
RSU grants are a form of compensation, not an open-market purchase or sale, and become actual shares only as they vest. The Form 4 records the grant value as $0 at issuance (common for equity awards); taxable and economic value to the recipient will depend on the market price when and if the RSUs vest and convert to shares. Such awards are routine executive compensation and should not be read as an immediate buying or selling signal.
