Earnings Per Share [Abstract] |
Computation of Earnings Per Share | NOTE E – COMPUTATION OF EARNINGS PER SHARE Basic earnings per share were computed by dividing Net income by the weighted-average number of common shares outstanding for each respective period. Diluted earnings per share were calculated by dividing Net income by the weighted-average of all potentially dilutive common stock that was outstanding during the periods presented. The calculation of basic and diluted earnings per share for the three and six months ended June 30, 2017 and 2016 was as follows:
|  | Three Months Ended June 30 |  |  | Six Months Ended June 30 |
|  | 2017 |  |  | 2016 |  |  | 2017 |  |  | 2016 |
