Context

• "Derivative" here indicates the disposals involved securities tied to awards or options; the footnote clarifies those underlying rights were fully vested and exercisable at sale time. The filing does not state motivations—sales by directors can be routine (diversification, tax planning, exercise/sell of vested awards), and do not necessarily signal a change in view about the company.
