13. Net Loss Per Share Attributable to Common Stockholders

The Company’s potential dilutive securities, which include common stock options and for the year ended December 31, 2018 included preferred stock,  have been excluded from the computation of diluted net loss per share as the effect would be anti‑dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at period end, from the computation of diluted net loss per share attributable to common stockholders for the period indicated because including them would have had an anti‑dilutive effect:
