The Risk & Control department and each internal audit department of major subsidiaries ("Internal Audit Department") play an important function in maintaining the Sony Group's governance in order to strengthen the Sony Group's management structure, promote efficiency of management, and maintain and avoid any loss of material assets, including Sony's brand image, by evaluating the effectiveness of the internal control system and risk management structure through independent and objective audit. The Risk & Control department and each Internal Audit Department conducts the internal audit of each department or subsidiary it supervises, guided by the annual audit plan that is established based on the risk assessments conducted in the beginning of each fiscal year and any matters proposed by Sony's management or the Audit Committee. Each internal audit is conducted under a planned audit procedure. Afterward, each Internal Audit Department follows up until the completion of any improvement plan based on the audit result.

The appointment and dismissal of the person in charge of each Internal Audit Department requires the prior approval of the person in charge of the Risk & Control department. The Internal Audit Departments of major subsidiaries are required to provide the Risk & Control department with a report on the material items and a copy of the issued audit report, and the Risk & Control department makes periodic presentations to the Audit Committee, the CFO, and the Corporate Executive Officer in charge of Internal Audit on these reports.
