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 outstandi ng stock equivalents during the three months ended March 31, 2014 and 2013. 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.
