Earnings Per Share [Abstract] |
Net Income (Loss) Per Share | Net Income (Loss) Per Share Basic net income (loss) per share is calculated based on the weighted-average number of common shares outstanding during the periods presented. Diluted net income (loss) per share is calculated 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, the net income (loss) available to common stockholders is equal to the reported net income (loss). For the three and six months ended June 30, 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 six months ended June 30, 2019, potentially dilutive securities consisted of common shares underlying outstanding stock options and RSUs. During the three and six months ended June 30, 2019, there were weighted average outstanding stock options and RSUs of 18.0 million and 18.4 million shares, respectively. The calculation of diluted earnings per share includes the weighted-average of potentially dilutive securities, which consists of shares of common stock underlying outstanding stock options and RSUs. The effect of these dilutive securities under the treasury stock method was approximately 10.9 million and 12.1 million shares for the three and six months ended June 30, 2018, respectively. During the three and six months ended June 30, 2018, shares of common stock underlying outstanding stock options totaling approximately 3.2 million and 3.1 million weighted-average shares outstanding, respectively, were excluded from the computation of diluted net income per share for that period because their effect was antidilutive.
