|  | 2019 |  |  | 2018 |
(table only in thousands) Numerator (for basic and diluted earnings (loss) per share) |  |  |  |  |  |  |  |
Net income (loss) |  | $ | 1,931 |  |  | $ | (12,915 | )
Denominator |  |  |  |  |  |  |  |
Basic weighted-average shares outstanding |  |  | 35,070 |  |  |  | 34,779 |
Common stock equivalents arising from stock options and restricted stock awards |  |  | 555 |  |  |  | — |
Diluted weighted-average shares outstanding |  |  | 35,625 |  |  |  | 34,779 |

(table only in thousands) Numerator (for basic and diluted earnings (loss) per share) |  |  |  |  |  |  |  |
Net income (loss) |  | $ | 9,310 |  |  | $ | (8,053 | )
Denominator |  |  |  |  |  |  |  |
Basic weighted-average shares outstanding |  |  | 34,944 |  |  |  | 34,681 |
Common stock equivalents arising from stock options and restricted stock awards |  |  | 579 |  |  |  | — |
Diluted weighted-average shares outstanding |  |  | 35,523 |  |  |  | 34,681 |
Options and restricted stock units included in the computation of diluted earnings per share are calculated using the treasury stock method. For the three-month periods ended September 30, 2019 and 2018, 0.4 million and 0.9 million, respectively, and during the nine-month periods ended September 30, 2019 and 2018, 0.5 million and 0.8 million, respectively, of outstanding options and restricted stock units were excluded from the computation of diluted earnings per share due to their having an anti-dilutive effect. Once a restricted stock unit vests, it is included in the computation of weighted average shares outstanding for purposes of basic and diluted earnings per share.
