Earnings Per Share [Abstract]

Earnings Per Share

Note 3 – Earnings Per Share

Basic earnings per share is computed using the weighted-average number of shares outstanding. Diluted earnings per share is computed using the weighted-average number of shares outstanding adjusted for the incremental shares attributed to outstanding stock equivalents during the three and nine months ended September 30, 2012 and 2011. Stock equivalents include common shares issuable upon the exercise of stock options and other equity instruments, and are computed using the treasury stock method. Under the treasury stock method, the exercise price of a share, the amount of compensation cost, if any, for future service that the Company has not yet recognized, and the amount of estimated tax benefits that would be recorded in paid-in-capital, if any, when the share is exercised are assumed to be used to repurchase shares in the current period.

The following table sets forth the calculation of basic and diluted earnings per share.

Options to purchase 3.8 million and 3.7 million common shares for the three and nine months ended September 30, 2012, respectively, were not included in the computation of diluted earnings per share because their effect would have been anti-dilutive. Options to purchase 3.8 million and 3.5 million common shares for the three and nine months ended September 30, 2011, respectively, were not included in the computation of diluted earnings per share because their effect would have been anti-dilutive.
