Earnings Per Share [Abstract] |
Net Income (Loss) Per Share | Net Income (Loss) Per Share We calculate basic net income (loss) per share based on the weighted-average number of common shares outstanding during the periods presented and calculate diluted net income (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 income (loss) available to common stockholders equals the reported net income (loss). For the three and nine months ended September 30, 2019 and the three months ended September 30, 2018, 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, 2019 and the three months ended September 30, 2018, potentially dilutive securities consisted of the weighted-average common shares underlying outstanding stock options and RSUs, which totaled 17.2 million, 18.0 million and 17.6 million shares, respectively. For the computation of diluted earnings per share for nine months ended September 30, 2018, we included approximately 11.3 million weighted-average common shares underlying stock options and RSUs under the treasury stock method and excluded approximately 3.2 million of shares of common stock underlying stock options because their effect was antidilutive.
