Board Leadership Structure and Role of our Lead Independent Director
We believe that the structure of our board of directors and its committees provides strong overall management
of our company. Our Chairman of our board of directors and our Chief Executive Officer roles are separate and our
independent directors have appointed a Lead Independent Director. This structure enables each person to focus on
different aspects of company leadership. Our Chief Executive officer is responsible for setting the strategic direction
of our company, the general management and operation of the business and the guidance and oversight of senior
management. The Chairman of our board of directors monitors the content, quality and timeliness of information
sent to our board of directors and is available for consultation with our board of directors regarding the oversight of
our business affairs.
