Context

• This was an option grant (a form of compensation), not an open‑market purchase or sale. Such director option awards are common as routine compensation and do not by themselves indicate insider buying or selling of stock. The options give the right to buy shares in the future; they were not exercised for shares or sold at the time of grant.
