Earnings per share (1): |
Earnings Per Share | 5. Earnings per Share Basic earnings per share have been computed based upon the weighted average number of common shares outstanding during each period. Diluted earnings per share include the effect of all potential common shares outstanding during each period. The diluted earnings per share computations for the three months ended March 31, 2020 and 2019 excluded 100,039 and 32,408, respectively, of unexercised stock options because their inclusion would have been anti-dilutive during such periods. The shares used in the calculation of basic and diluted earnings per share are shown below:
