Internal Audit Structure

Basic Approach

Internal audits are designed as an integrated process, independent from other business operations, for evaluating the extent to which internal control achieves its objectives in key areas, including appropriate risk management; efficient and effective business operations; reliable financial reporting; and compliance with laws, regulations, and internal rules. We conduct internal audits from an objective and comprehensive standpoint, independent of operational reporting lines, and offer advice and remedial recommendations in connection with any problems that may be identified. Through this process, internal audits assist the Boards of Directors of each of our group companies to fulfill their managerial duties efficiently and effectively.

In line with the Basic Policy for Internal Audit established by Mizuho Financial Group, our core group companies conduct internal audits, which include the auditing of their respective subsidiaries. In addition, with respect to the management of risks applicable across the group, we coordinate internal audits throughout the group to assess the risk management status of the group as a whole.

Internal Audit Management Structure

Mizuho Financial Group

Our Internal Audit Committee, which determines all important matters concerning internal audits, is chaired by the President & Group CEO and is independent of our other business operations. The Committee monitors and manages internal audits at our core group companies based on internal audit reports submitted by the companies.

Our Internal Audit Committee discusses and makes decisions regarding internal audits at our core group companies and submits these decisions, together with the results of their examination of the internal audit reports, to the Audit Committee and our Board of Directors.

Mizuho Bank and Mizuho Trust & Banking

Mizuho Bank and Mizuho Trust & Banking have also established Internal Audit Committees that are independent of their other business operations. The two banks have established internal audit departments to conduct internal audits at their respective domestic and overseas offices, head office departments, and group companies. Specifically, we assess the suitability and effectiveness of business activities associated with compliance and risk management.

Other Core Group Companies

Other core group companies have also established effective and efficient internal audit structures adapted to the characteristics of their respective businesses.
