|  | 2018 |  |  | 2017 |  |  | 2016 |
Numerator: |  |  |  |  |  |  |  |  |  |  |  |
Net income (loss) |  | $ | 4,968 |  |  | $ | (2,139 | ) |  | $ | (12,129 | )
Denominator: |  |  |  |  |  |  |  |  |  |  |  |
Weighted average common shares: |  |  |  |  |  |  |  |  |  |  |  |
Common shares outstanding |  |  | 42,598 |  |  |  | 41,025 |  |  |  | 40,352 |
Less: Unvested restricted stock |  |  | (11 | ) |  |  | (21 | ) |  |  | (23 | )
Denominator for basic calculation |  |  | 42,587 |  |  |  | 41,004 |  |  |  | 40,329 |
Weighted average effects of potentially diluted common stock: |  |  |  |  |  |  |  |  |  |  |  |

Net income (loss) per share: |  |  |  |  |  |  |  |  |  |  |  |
Basic |  | $ | 0.12 |  |  | $ | (0.05 | ) |  | $ | (0.30 | )
Diluted |  | $ | 0.11 |  |  | $ | (0.05 | ) |  | $ | (0.30 | )
Because the Company had a net loss for the years ended 2017 and 2016, the number of diluted shares is equal to the number of basic shares. Outstanding options, 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 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.
