Internal Control Self-Assessment Report

Important Statement

According to the provisions of the Basic Norms for Enterprise Internal Control and its supporting guidelines, as well as other internal control regulatory requirements, the company has evaluated the effectiveness of its internal controls as of December 31, 2022, based on daily supervision and special supervision of internal controls.

The establishment, improvement, and effective implementation of internal controls, as well as the truthful disclosure of the internal control evaluation report, are the responsibilities of the company's board of directors. The supervisory board oversees the establishment and implementation of internal controls by the board. The management is responsible for organizing and leading the daily operation of internal controls. The board of directors, supervisory board, and directors, supervisors, and senior management ensure that the content of this report does not contain any false records, misleading statements, or significant omissions, and bear individual and joint legal responsibility for the truthfulness, accuracy, and completeness of the report.

The goal of the company's internal controls is to reasonably ensure that business management is legal and compliant, assets are secure, financial reports and related information are true and complete, operational efficiency and effectiveness are improved, and the development strategy is promoted. Due to inherent limitations in internal controls, they can only provide reasonable assurance of achieving these objectives. Additionally, changes in circumstances may render internal controls inappropriate or reduce compliance with control policies and procedures, making it risky to infer the future effectiveness of internal controls based on evaluation results.
