5. Stockholders’ Investment

Common Stock — Our authorized capital stock consists of 60,000,000 shares of common stock with a par value of $0.01 per share, with 28,769,799 shares outstanding as of June 30, 2011.

Preferred Stock — Our authorized capital stock consists of 5,000,000 shares of preferred stock with a par value of $0.01 per share, with no preferred shares outstanding as of June 30, 2011.

Earnings Per Share — Basic earnings per share is determined by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share, and all other diluted per share amounts presented, is determined by dividing net income by the weighted average number of common shares and potential common shares outstanding during the period as determined by the Treasury Stock Method. Potential common shares are included in the diluted earnings per share calculation when dilutive. Diluted earnings per share for the three and six months ended June 30, 2011 and 2010 includes the effects of potential common shares consisting of common stock issuable upon exercise of outstanding stock options when dilutive (in thousands, except per share amounts):
