NET LOSS PER SHARE

13. NET LOSS PER SHARE

The Company’s potential dilutive securities, which include unvested common stock from the early-exercise of stock options and outstanding common stock options, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. 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 December 31, 2019 and 2018, from the computation of diluted net loss per share attributable to common stockholders because including them would have had an anti-dilutive effect:

	As of December 31,
	2019		2018
Unvested common stock from early exercise of options		21,666		151,289
Stock options to purchase common stock		4,843,018		3,203,122
Total		4,864,684		3,354,411
