ITEM 9A. CONTROLS AND PROCEDURES Disclosure Controls and Procedures The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of December 31, 2023. Based on that evaluation, the Company's Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer) concluded that, as of December 31, 2023, the Company's disclosure controls and procedures were effective to ensure that information required to be disclosed in reports the Company files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) accumulated and communicated to management to allow their timely decisions regarding required disclosure. Changes in Internal Control over Financial Reporting There have been no changes in our internal control over financial reporting that occurred during the three months ended December 31, 2023, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. In order to evaluate the effectiveness of internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, management, with the participation of Company's Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), has conducted an assessment, including testing, using the criteria in Internal Control – Integrated Framework ( 2013 ), issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). The Company’s system of internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Based on its assessment, management has concluded that the Company maintained effective internal control over financial reporting as of December 31, 2023, based on criteria in Internal Control – Integrated Framework ( 2013 ), issued by the COSO. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2023, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report, which is included in Item 8. ITEM 9B.
