| We have chosen to conduct the Annual Meeting in a virtual-only meeting format, via live audio webcast. A virtual meeting provides a convenient and efficient means to administer our Annual Meeting while enabling increased stockholder attendance and participation because stockholders can participate from any location around the world. |
