Stockholders' Equity

Stockholders’ Equity

Preferred Stock

We may issue up to 5.0 million shares of our preferred stock in one or more series. 0.5 million of these shares are designated as Series A Junior Participating Preferred Stock. Our Board of Directors is authorized to fix the rights and terms for any series of preferred stock without additional shareholder approval.

Common Stock

Our Articles of Organization authorize us to issue up to 500 million shares of our common stock. Our Board of Directors has periodically authorized the repurchase of shares of our common stock. For the period of October 1, 2012 through September 30, 2013, we were authorized to repurchase up to $100 million worth of shares with cash from operations. We repurchased 3.1 million shares at a cost of $74.9 million in 2013, 1.6 million shares at a cost of $35.0 million in 2012, and 2.6 million shares at a cost of $54.9 million in 2011. All shares of our common stock repurchased are automatically restored to the status of authorized and unissued. Future repurchases of shares will reduce our cash balances.
