Under such rules, only one Notice or, if paper copies are requested, only one Proxy Statement and Annual Report on Form 10-K are delivered to multiple stockholders sharing an address unless the Company has received contrary instructions from one or more of the stockholders. If a stockholder sharing an address wishes to receive a separate Notice or copy of the proxy materials, he or she may so request by contacting Broadridge Householding Department by phone at 866-540-7095 or by mail to Broadridge Householding Department, 51 Mercedes Way, Edgewood, New York 11717. A separate copy will be promptly provided following receipt of a stockholder’s request, and such stockholder will receive separate materials in the future. Any stockholder currently sharing an address with another stockholder but nonetheless receiving separate copies of the materials may request delivery of a single copy in the future by contacting Broadridge Householding Department at the number or address shown above. |
