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 us to repurchase shares of our common stock. Under our current authorization, approved by our Board of Directors in September 2012, we are authorized to repurchase up to $100 million worth of shares with cash from operations in the period October 1, 2012 through September 30, 2013. In 2012, we repurchased 1.6 million shares at a cost of $35.0 million. In 2011 and 2010, we repurchased 2.6 million shares at a cost of $54.9 million and 3.7 million shares at a cost of $62.5 million, respectively. 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.
