9. 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 June 30, 2018 and 2017, 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 June 30,
	2018		2017
Convertible preferred shares (as converted to common stock)		—		11,831,489
Unvested common stock from early exercise of options		219,747		360,335
Stock options to purchase common stock		2,641,800		897,622
Total		2,861,547		13,089,446
