Net Loss Per Share

10. NET LOSS PER SHARE

Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding. Diluted net loss per share is computed similarly to basic net loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. Diluted net loss per share is the same as basic net loss per common share, since the effects of potentially dilutive securities are antidilutive.

As of December 31, 2018 and 2017, the number of shares of common stock underlying potentially dilutive securities include:

Options to purchase common stock		781,725		463,600
