Earnings per Share (EPS) and Common Stock

EPS

Basic EPS is calculated by dividing net income by the weighted average number of shares outstanding during the period. Unvested restricted stock, although legally issued and outstanding, is not considered outstanding for purposes of calculating basic EPS. Diluted EPS is calculated by dividing net income by the weighted average number of shares outstanding plus the dilutive effect, if any, of outstanding stock options, restricted shares and RSUs using the treasury stock method. The calculation of the dilutive effect of outstanding equity awards under the treasury stock method includes consideration of proceeds from the assumed exercise of stock options, unrecognized compensation expense and any tax benefits as additional proceeds.

Stock options to purchase 0.2 million shares for the first quarter of 2012 and 0.1 million shares for the first quarter of 2011 were outstanding but were not included in the calculation of diluted EPS because the exercise prices per share were greater than the average market price of our common stock for those periods. These shares were excluded from the computation of diluted EPS as the effect would have been anti-dilutive.

Common Stock Repurchases

Our Articles of Organization authorize us to issue up to 500 million shares of our common stock. Our Board of Directors has authorized us to repurchase up to $100 million worth of shares with cash from operations in the period October 1, 2011 through September 30, 2012. We did not repurchase any shares in the first quarter of either 2012 or 2011. All shares of our common stock repurchased are automatically restored to the status of authorized and unissued.
