Earnings Per Share [Abstract] |
Computation of Earnings Per Share | Note I - 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 shares that were outstanding during the years presented. The calculation of basic and diluted earnings per share for the year ended December 31 was as follows:
|  | 2019 |  |  | 2018 |  |  | 2017 |
Numerator |  |  |  |  |  |  |  |  |  |  |  |
Net income |  | $ | 23,303 |  |  | $ | 26,581 |  |  | $ | 12,654 |
Denominator |  |  |  |  |  |  |  |  |  |  |  |
Determination of shares (in thousands) |  |  |  |  |  |  |  |  |  |  |  |
Weighted-average common shares outstanding |  |  | 5,031 |  |  |  | 5,032 |  |  |  | 5,102 |
Dilutive effect - share-based awards |  |  | 56 |  |  |  | 75 |  |  |  | 31 |
Diluted weighted-average common shares outstanding |  |  | 5,087 |  |  |  | 5,107 |  |  |  | 5,133 |
Earnings per common share |  |  |  |  |  |  |  |  |  |  |  |
Basic |  | $ | 4.63 |  |  | $ | 5.28 |  |  | $ | 2.48 |
Diluted |  | $ | 4.58 |  |  | $ | 5.21 |  |  | $ | 2.47 |
For the year ended December 31, 2019, 2018 and 2017, 15,041, 260 and 13,000 stock options, respectively, were excluded from the calculation of diluted earnings per share as the effect would have been anti-dilutive.
