Under the Corporate Governance Guidelines of the company, the Board is free to select its Chairman and company's CEO in the manner it considers to be in its best interests at any given point in time. Since 2008 the positions of Chairman of the Board and CEO have been held by separate persons. The Board believes that this structure is appropriate for them because it allows CEO to focus his time and energy on leading its key business and strategic initiatives while the Board focuses on oversight of management, overall enterprise risk management and corporate governance. The Board and its committees meet throughout the year on a set schedule, usually at least once a quarter, and also hold special meetings from time to time. Agendas and topics for Board and committee meetings are developed through discussions between management and members of the Board and its committees.
