Earnings Per Share [Abstract] |
Net Income Per Share Data | 12. Net Income Per Share Data Basic net income per common share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the weighted average number of common and dilutive common equivalent shares outstanding during the period. The Company’s potentially dilutive common shares are those that result from dilutive common stock options, non-vested stock relating to restricted stock awards, restricted stock units and deferred stock units, as well as performance shares in years prior to fiscal 2020. Options to purchase shares of common stock as well as unvested restricted stock and performance stock units are considered to be potentially dilutive common shares. The calculation of weighted average diluted shares outstanding excludes outstanding stock options associated with the right to purchase 0.1 million shares of common stock for both the three months ended December 31, 2019 and 2018, as their inclusion would have had an antidilutive effect on diluted net income per share for those periods. The following table sets forth the denominator for the computation of basic and diluted net income per share (in thousands):
|  | Three Months Ended |
|  | December 31, |
|  | 2019 |  |  | 2018 |
Net income available to common shareholders |  | $ | 148 |  |  | $ | 1,310 |
Basic weighted average shares outstanding |  |  | 13,469 |  |  |  | 13,367 |
Dilutive effect of outstanding stock options, non-vested restricted stock, restricted stock units, deferred stock units and performance shares |  |  | 300 |  |  |  | 460 |
Diluted weighted average shares outstanding |  |  | 13,769 |  |  |  | 13,827 |
The Company’s Board of Directors has authorized the repurchase of up to $25.3 million of the Company’s outstanding common stock. This authorization does not have an expiration date.
