Earnings Per Share [Abstract]
Net Loss Per Share	Net Loss Per ShareWe 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 months ended March 31, 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 months ended March 31, 2020 and March 31, 2019, potentially dilutive securities consisted of the weighted-average common shares underlying outstanding stock options and RSUs, which totaled 18.8 million and 18.9 million shares, respectively.
