We establish internal audit programs, which include reviewing and inspecting the sufficiency and adequacy of the internal control system, providing timely recommendations for improvement, and ensuring the sustained effectiveness of the internal control system. The frequency and content of the audit for each transaction cycle shall be as prescribed by the laws and regulations and be based on the evaluation of internal and external environment and risk assessment. The major procedures or specific items shall be inspected from time to time. The internal audit personnel shall also produce periodic reports that track the audited unit's response to the findings and recommendations of audit reports.
