Context

These are non-cash equity awards (RSUs and a derivative/option-like grant) that give the director a future right to receive common stock if vesting conditions are met; they are typical compensation/retention arrangements and do not reflect an open-market purchase or sale. Vesting accelerates on a Change in Control and is otherwise contingent on continued service through the vesting date.
