CAPITAL STOCK	CAPITAL STOCK Common Stock - We are authorized to issue 75,000,000 shares of common stock. Holders of common stock are entitled to one vote for each share held of record on each matter submitted to a vote of shareholders. Holders of our common stock do not have a cumulative voting right, which means that the holders of more than one half of our outstanding shares of common stock, subject to the rights of the holders of preferred stock, can elect all of our directors, if they choose to do so. In this event, the holders of the remaining shares of common stock would not be able to elect any directors. Subject to the prior rights of any class or series of preferred stock which may from time to time be outstanding, if any, holders of common stock are entitled to receive ratably, dividends when, as and if declared by our Board of Directors out of funds legally available for that purpose and, upon our liquidation, dissolution, or winding up, are entitled to share ratably in all assets remaining after payment of liabilities and payment of accrued dividends and liquidation preferences on the preferred stock, if any. Holders of common stock have no preemptive rights and have no rights to convert their common stock into any other securities. The outstanding common stock is duly authorized and validly issued, fully-paid and non-assessable. Except as otherwise required by Delaware law and subject to the rights of the holders of preferred stock, all stockholder action is taken by the vote of a majority of the outstanding shares of common stock present at a meeting of shareholders at which a quorum consisting of a majority of the outstanding shares of common stock is present in person or by proxy. Shares repurchased are held as treasury shares and used for general corporate purposes including, but not limited to, satisfying obligations under our employee benefit plans.
