Our board of directors currently consists of six persons. The board has three functioning committees, the audit committee, compensation committee and nominating and corporate governance committee. Because a single person controls our Company, we are a "controlled company" within the meaning of the rules of the New York Stock Exchange; accordingly, we are not required to have independent compensation and nominating and corporate governance committees. We have determined, however, that it is in the best interests of the Company to maintain an independent compensation committee, and our compensation committee charter requires that such committee be composed solely of independent directors.
