Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Exchange Act. Because of inherent limitations, a system of 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 due to a change in conditions, or that the degree of compliance with policies or procedures may deteriorate.

Our management evaluated, with the participation of our principal executive officer and principal financial officer, the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) (2013) in “Internal Control-Integrated Framework.” Based on that evaluation, our principal executive officer and principal financial officer concluded that our internal control over financial reporting was effective as of the end of the period covered by this report.

The Company’s internal control over financial reporting as of December 31, 2023 has been audited by BDO USA, P.C., the independent registered public accounting firm that also audited the Company’s consolidated financial statements included in this Annual Report on Form 10-K. The attestation report of BDO USA, P.C. on the effectiveness of the Company’s internal control over financial reporting appears on page F-5 herein.
