Net Loss Per Share

9 Months Ended

Sep. 30, 2021

We calculate basic net loss per share based on the weighted-average number of common shares outstanding during the periods presented and calculate diluted net loss per share based on the weighted-average number of shares of common stock outstanding, including potentially dilutive securities. For all periods presented in the accompanying Condensed Consolidated Statements of Operations, our net loss available to common stockholders equals the reported net loss.

For the three and nine months ended September 30, 2021 and 2020, basic and diluted net loss per share are the same due to our net losses and the requirement to exclude potentially dilutive securities which would have an antidilutive effect on net loss per share. During the three and nine months ended September 30, 2021 and 2020, potentially dilutive securities consisted of

weighted-average common shares underlying outstanding stock options and RSUs as follows (in thousands):


	Three months ended September 30,		Nine months ended September 30,
	2021	2020	2021	2020
Potentially dilutive securities	17,634	16,575	18,454	17,499
