|  | Three Months Ended |
|  | March 30, 2018 |  | March 31, 2017 |
Numerator: |  |  |  |  |  |  |
Net income (loss) |  | $ | 583 |  | $ | (2,203) |
Denominator: |  |  |  |  |  |  |
Weighted average common shares and denominator for basic calculation: |  |  |  |  |  |  |
Weighted average common shares outstanding |  |  | 41,431 |  |  | 40,772 |
Less: Unvested restricted stock |  |  | (21) |  |  | (23) |
Denominator for basic calculation |  |  | 41,410 |  |  | 40,749 |
Weighted average effects of potentially dilutive common stock: |  |  |  |  |  |  |
Stock options |  |  | 1,396 |  |  | — |
Unvested restricted stock |  |  | 264 |  |  | — |
Restricted stock units |  |  | 17 |  |  | — |
Warrants |  |  | — |  |  | — |
Denominator for diluted calculation |  |  | 43,087 |  |  | 40,749 |
Net income (loss) per share – basic |  | $ | 0.01 |  | $ | (0.05) |
Net income (loss) per share – diluted |  | $ | 0.01 |  | $ | (0.05) |
Because the Company had a net loss for the quarter ended March 31, 2017, the number of diluted shares is equal to the number of basic shares. Outstanding options and warrants to purchase common stock, restricted stock and restricted stock units would have had an anti-dilutive effect on diluted per share amounts. The following table sets forth (in thousands) the weighted average number of options and warrants to purchase shares of common stock, restricted stock, and restricted stock units with either exercise prices or unrecognized compensation cost per share greater than the average market price per share of the Company’s common stock, which were not included in the calculation of diluted per share amounts because the effects would be anti-dilutive.
|  | Three Months Ended |

Options |  | $ | 385 |  | $ | 2,567 |
Restricted stock and restricted stock units |  |  | 4 |  |  | 146 |
Total |  | $ | 389 |  | $ | 2,713 |
