The Chairman’s Committee performs the collective tasks of a nominating, compensation and corporate governance committee to the extent that the tasks are not performed by the Nominating Committee. In particular, it makes proposals regarding the appointment of Managing Board members and establishes guidelines for the conditions of employment and for the structure and level of the remuneration of Managing Board members.
The Audit Committee consists of three shareholder representatives and three employee representatives. The Supervisory Board monitors the independence of the members of the committee and sees to it that they have special knowledge and experience in the application of accounting principles and internal control processes. Siemens relies on the exemption afforded by Rule 10A-3(b)(1)(iv)(C) under the Securities Exchange Act. We believe that such reliance does not materially adversely affect the ability of the Audit Committee to act independently or to satisfy the other requirements of Rule 10A-3. The Audit Committee oversees the appropriateness and the effectiveness of the Company’s external and internal accounting processes. Together with the independent auditors, it also reviews the Company’s financial statements prepared quarterly, half-yearly and annually by management. On the basis of the independent auditors’ report on the annual financial statements, the Audit Committee makes a recommendation to the Supervisory Board whether or not it should approve those financial statements. In addition, the Audit Committee oversees the Company’s internal control system related to financial reporting and its procedures for assessing, monitoring and managing risk. The Company’s Financial Audit department reports regularly to the Audit Committee. In addition, the Audit Committee monitors the independence, qualifications, rotation and performance of the independent auditors and performs the other functions required of it under the SOA.
For the remainder of the current internal investigations, the Compliance Committee will deal with the following matters on behalf of the Supervisory Board: overseeing the ongoing compliance-related investigations, processing reports by the law firm Debevoise & Plimpton LLP on its independent investigation and review of Siemens’ internal compliance and control systems, and monitoring compliance with legal and regulatory requirements and Company guidelines.
The Mediation Committee submits proposals to the Supervisory Board in the event that the Supervisory Board cannot reach the two-thirds majority required to appoint a Managing Board member.
In July 2007, the Supervisory Board established a Nominating Committee. It is composed of the Chairman of the Supervisory Board and two shareholder representatives. This Nominating Committee is responsible for making recommendations to the Supervisory Board’s shareholder representatives on the shareholder candidates for election to the Supervisory Board by the Annual Shareholders’ Meeting.
