Earnings Per Share [Abstract] |
Income (Loss) Per Share | INCOME (LOSS) PER SHARE Basic net income (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted-average number of common shares and the effect of potentially dilutive securities outstanding during the period. Potentially dilutive securities include stock options, restricted stock units, performance share units, unvested restricted stock awards, ESPP shares, warrants and convertible senior notes. If dilutive, those potentially dilutive securities are reflected in diluted net income (loss) per share by application of the treasury stock method, except for the convertible senior notes, which are subject to the if-converted method. Each share of the Company's Class A and Class B common stock automatically converted into a single class of common stock on October 31, 2016. Refer to Note 8, Stockholders’ Equity and Compensation Arrangements, for additional information. Prior to the conversion, the Company computed net income (loss) per share of Class A and Class B common stock using the two-class method. Under the two-class method, the undistributed earnings for each period were allocated based on the contractual participation rights of the Class A and Class B common shares as if the earnings for the period had been distributed. As the liquidation and dividend rights were identical for Class A and Class B common shares, the undistributed earnings were allocated on a proportionate basis. Under the two-class method, the computation of diluted net income (loss) per share of Class A common stock would reflect the conversion of Class B common stock, if dilutive, while the computation of diluted net income (loss) per share of Class B common stock would not reflect the conversion of those shares. The following table sets forth the computation of basic and diluted net income (loss) per share of common stock for the three and nine months ended September 30, 2017 (in thousands, except share amounts and per share amounts):

(1) | The potentially dilutive impact of the warrants and the convertible senior notes has been excluded from the calculation of diluted net income (loss) per share for the three and nine months ended September 30, 2017 as the effect on net income (loss) per share from continuing operations was antidilutive. The potentially dilutive impact of equity awards has also been excluded from the calculation of diluted net income (loss) per share for the nine months ended September 30, 2017 as the effect on net income (loss) per share from continuing operations was antidilutive.

(1) | The potentially dilutive impacts of a conversion of Class B to Class A shares, outstanding equity awards, warrants and convertible senior notes have been excluded from the calculation of diluted net income (loss) per share for the three and nine months ended September 30, 2016 as their effect on net income (loss) per share from continuing operations was antidilutive.
The following weighted-average outstanding potentially-dilutive securities are not included in the diluted net income (loss) per share calculations above because they would have had an antidilutive effect on the net income (loss) per share from continuing operations:

The Company had outstanding performance share units as of September 30, 2017 and 2016 that were eligible to vest into shares of common stock subject to the achievement of specified performance conditions. Contingently issuable shares are excluded from the computation of diluted earnings per share if, based on current period results, the shares would not be issuable if the end of the reporting period were the end of the contingency period. There are 1,876,785 and 778,092 performance share units for the three months ended September 30, 2017 and 2016, respectively, and 1,179,984 and 525,861 performance share units for the nine months ended September 30, 2017 and 2016, respectively, that were excluded from the table above as the performance conditions were not satisfied as of the end of the respective periods.
