Net Loss Per Share

9 Months Ended

Sep. 30, 2020

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, 2020 and 2019, 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, 2020 and 2019, 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,
	2020	2019	2020	2019
Potentially dilutive securities	16,575	17,163	17,499	18,012
