Our Annual Report to stockholders on Form 10-K for the year ended December 31, 2023, including audited financial statements, accompanies this Proxy Statement. Copies of our Annual Report on Form 10-K and the exhibits thereto are available from us without charge upon written request of a stockholder to our investor relations department at 1000 Skokie Blvd., Suite 350, Wilmette, IL 60091. Copies of these materials are also available online through the SEC at www.sec.gov. We may satisfy SEC rules regarding delivery of materials, including the Proxy Statement and Annual Report on Form 10-K by delivering a single Proxy Statement and Annual Report on Form 10-K to an address shared by two or more of our stockholders. This delivery method can result in meaningful cost savings for us. In order to take advantage of this opportunity, we may deliver only one Proxy Statement and Annual Report on Form 10-Kto multiple stockholders who share an address, unless contrary instructions are received from one or more stockholders at that address prior to the mailing date. We undertake to deliver promptly upon written or oral request a separate copy of the Proxy Statement and Annual Report on Form 10-K to a stockholder at a shared address to which a single copy of these materials was delivered. If you hold stock as a registered holder and prefer to receive separate copies of these materials either now or in the future, please contact our investor relations department at 1000 Skokie Blvd., Suite 350, Wilmette, IL 60091 or by telephone at (847) 388-0349.
