The Board has not adopted a formal policy regarding whether the roles of the Chairman and Chief Executive Officer should be separate or combined but recognizes the value to the Company of the separation of these positions and having an independent director serve as Chairman. We believe that this structure is appropriate for the Company because it allows our independent Chairman to lead the Board in its fundamental role of governing the Company and providing advice to management, while also providing for effective independent oversight and allowing our President and Chief Executive Officer to focus on the execution of our business strategy, growth and development. The Board evaluates whether this leadership structure is in the best interests of our stockholders on a regular basis.
