Earnings Per Share [Abstract] |
Income Per Share of Common Stock | INCOME PER SHARE OF COMMON STOCK Basic earnings per share is computed by dividing net income attributable to Ark Restaurants Corp. by the weighted-average number of common shares outstanding for the period. Our diluted earnings per share is computed similarly to basic earnings per share, except that it reflects the effect of common shares issuable upon exercise of stock options, using the treasury stock method in periods in which they have a dilutive effect. A reconciliation of shares used in calculating earnings per basic and diluted share follows:
|  | 13 Weeks Ended
|  | December 28, |  | December 29,
|  | 2019 |  | 2018
Basic | 3,499 |  |  | 3,474 |
Effect of dilutive securities: |  |  |
Stock options |  | 42 |  |  | — |
Diluted |  | 3,541 |  |  | 3,474 |
For the 13-week period ended December 28, 2019, the dilutive effect of options to purchase 192,000 shares of common stock at exercise prices ranging from $22.30 per share to $22.50 per share were not included in diluted earnings per share as their impact would have been anti-dilutive. For the 13-week period ended December 29, 2018 all options were excluded from diluted earnings per share as all were anti-dilutive.
