Participating in the Annual Meeting

Virtual Meeting
This year’s Annual Meeting will be accessible through the Internet. We are conducting a virtual online Annual Meeting so our shareholders can participate from any geographic location with Internet connectivity. We believe this enhances accessibility to our Annual Meeting for all of our shareholders and reduces the carbon footprint of our activities. We have worked to offer the same rights and opportunities for shareholders to participate virtually as those previously provided during in-person shareholder meetings, while also providing an online experience available to all shareholders regardless of their location.
