■  Board of Corporate Auditors ■  Outside Directors and Outside 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. 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. As a general rule, the Board of Corporate Auditors  meets once a month.
