## ■  Board of Corporate Auditors 

Astellas uses a Corporate Auditor System. The Board of Corporate Auditors consists of four Corporate Auditors, including two outside ones, and each Corporate Auditor conducts audits of performance of duties by Directors. Audits are carried out effectively by both full-time internal Corporate Auditors, who are very familiar with issues in the Company, and outside Corporate Auditors, who have a high degree of independence and a wealth of actual  experience and familiarity in various specialist fields.  Furthermore, a full-time staff member is assigned to assist the Corporate Auditors in carrying out their duties. The function of the Corporate Auditors is enhanced through cooperation with the Accounting Auditors and the Internal Auditing Department. 

As a general rule, the Board of Corporate Auditors meets once a month. 

## ■  Outside Directors and Outside Corporate Auditors 

All four outside Directors are independent Directors with no conflict of interest with general shareholders. Each outside Director has a specific area of expertise, such as business management, law, or medicine. They make use of their wide-ranging experience and expertise to participate in decision-making at Board of Directors meetings and oversee business execution from an independent standpoint. 

Both of the two outside Corporate Auditors are also independent Auditors. They draw on their specific expertise in such areas as finance, accounting, and business management, and their extensive experience to audit the Directors’ performance of their duties from an independent standpoint.
