The details are as follows:
I. Important Statement In accordance with the "Basic Norms for Enterprise Internal Control", it is the responsibility of the company's board of directors to establish, improve, and effectively implement internal control, evaluate its effectiveness, and disclose the internal control evaluation report truthfully. The Audit Committee supervises the board of directors in establishing and implementing internal control. Management is responsible for organizing and leading the daily operation of the company's internal control. The company's board of directors, directors, and senior management guarantee that the report contains no false records, misleading statements, or major omissions, and shall bear individual and joint legal responsibility for the truthfulness, accuracy, and completeness of the report. The objective of the company's internal control is to reasonably ensure the legality and compliance of business operations, the safety of assets, and the truthfulness and completeness of financial reports and related information, to improve operational efficiency and effectiveness, and to promote the realization of development strategies. Due to the inherent limitations of internal control, it can only provide reasonable assurance for the achievement of these objectives. In addition, due to changes in circumstances that may render internal control inappropriate, or a decrease in the degree of adherence to control policies and procedures, there is a risk in inferring the effectiveness of future internal control based on the results of the internal control evaluation.
II. Conclusion of Internal Control Evaluation Based on the determination of major defects in the company's financial reporting internal control, as of the base date of the internal control evaluation report, there were no major defects in financial reporting internal control. The board of directors believes that the company has maintained effective financial reporting internal control in all material respects in accordance with the requirements of the enterprise internal control norm system and relevant regulations. Based on the determination of major defects in the company's non-financial reporting internal control, as of the base date of the internal control evaluation report, the company found no major defects in non-financial reporting internal control. No factors have occurred between the base date of the internal control evaluation report and the date of issuance of the internal control evaluation report that affect the conclusion of the effectiveness evaluation of internal control.
