Diluted weighted-average common shares outstanding |  | 37,838 |  |  | 37,249 |  |  | 37,789 |  |  | 36,233
Diluted income (loss) per common share | $ | 0.07 |  | $ | 0.01 |  | $ | 0.07 |  | $ | (0.10)
We excluded stock options from the calculation of diluted weighted-average common shares outstanding if the per share value, including the sum of (i) the exercise price of the options and (ii) the amount of the compensation cost attributed to future services and not yet recognized, was greater than the average market price of the shares because the inclusion of these stock options would be antidilutive to loss per common share. Accordingly, for the three and six months ended June 30, 2019 stock options to purchase a weighted-average of 158,000 and 105,000 shares, respectively, were antidilutive and excluded from the calculation of diluted weighted-average common shares outstanding. For the three months ended June 30, 2018 stock options to purchase a weighted-average of 219,000 shares were antidilutive and excluded from the calculation of diluted weighted-average common shares outstanding. For the six months ended June 30, 2018 all stock options and awards were excluded from the calculation of diluted weighted-average common shares outstanding as these would be antidilutive due to the net loss.
