Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company’s reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including the Company’s Chairman and Chief Executive Officer and the Company’s Executive Vice President, Chief Financial Officer and Treasurer, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. The Company’s management, with the participation of the Company's Chairman and Chief Executive Officer and the Company’s Executive Vice President, Chief Financial Officer and Treasurer, has evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K. Based upon that evaluation, the Company’s Chairman and Chief Executive Officer and the Company’s Executive Vice President, Chief Financial Officer and Treasurer concluded that, as of December 31, 2025, the Company’s disclosure controls and procedures were effective to accomplish their objectives.
