Management recognizes that all internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to risk. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

Under the supervision and with the participation of the Company’s principal executive officer and principal financial officer, management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2024.
