11.	Net Loss Per Share Available to Common Stockholders

Basic net loss per share of common stock is calculated by dividing the net loss available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Diluted net loss per share of common stock is computed by dividing the net loss using the weighted-average number of shares of common stock, excluding common stock subject to repurchase, and, if dilutive, potential shares of common stock outstanding during the period. Basic and diluted net loss per share is the same for all periods presented, as the impact of all potentially dilutive outstanding securities was anti-dilutive.

The following table presents the calculation of basic and diluted net loss per share for the periods presented:

	Three Months Ended June 30,						Six Months Ended June 30,
	2019			2018			2019			2018

The following table presents the potential shares of common stock outstanding that were excluded from the computation of diluted net loss per share available to common stockholders for the periods presented because including them would have been anti-dilutive:

	Three and Six Months Ended June 30, June 30,
	2019	2018
Options to purchase common stock	553	548
Unvested RSUs	1,152	938
