Earnings Per Share [Text Block] | 10. PER SHARE DATA The Company uses the treasury stock method to calculate the weighted-average shares used for diluted earnings per share. The number of common shares used to calculate basic and diluted earnings per share for the fiscal years ended December 30, 2017 and December 31, 2016 was determined as follows:
|  | Fiscal Years Ended |
|  | December 30, 2017 |  |  | December 31, 2016 |
Basic weighted average shares outstanding |  |  | 11,995,341 |  |  |  | 12,302,558 |

Weighted average dilutive shares outstanding |  |  | 12,117,201 |  |  |  | 12,423,348 |
For the year ended December 30, 2017 there were no anti-dilutive shares not included in the calculation of common stock equivalents. For the year ended December 31, 2016 there were 40,000 anti-dilutive shares not included in the calculation of common stock equivalents.
