Context RSUs are awards representing the right to receive shares in the future if vesting conditions are met; they are not open‑market purchases or sales. This grant is a routine, compensation-related award for a non-employee director and does not by itself indicate buying or selling sentiment. The derivative-classed portion simply reflects reporting convention for contingent rights to receive shares.
