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 stockholders can participate from any geographic location with Internet connectivity. We believe this enhances accessibility to our Annual Meeting for all of our stockholders and reduces the carbon footprint of our activities. We have worked to offer the same rights and opportunities for stockholders to participate virtually as those previously provided during in-person stockholder meetings, while also providing an online experience available to all stockholders regardless of their location.
