Earnings Per Share [Abstract] |
NET INCOME (LOSS) PER SHARE | NET INCOME (LOSS) PER SHARE Basic net income (loss) per share is computed by dividing the net income (loss) by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding adjusted for the dilutive effect of all potential shares of common stock. In periods when the Company reported a net loss, diluted net loss per share is the same as basic net loss per share because the effects of potentially dilutive items were anti-dilutive. The following table presents the calculation of basic and diluted net income (loss) per share (in thousands, except per share data):

Diluted | $ | 0.06 |  |  | $ | 0.04 |  |  | $ | (0.04 | ) |  | $ | (0.03 | )
Additionally, since the Company intends to settle future conversions of its outstanding 2022 Notes and 2023 Notes entirely in shares of its Class A common stock, the Company will consider the number of shares expected to be issued in calculating any potential dilutive effect of the conversions, if applicable. The following potential common shares were excluded from the calculation of diluted net income (loss) per share because their effect would have been anti-dilutive for the periods presented (in thousands):
| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2019 |  | 2018 |  | 2019 |  | 2018
Stock options and restricted stock units | 15,113 |  |  | 12,079 |  |  | 46,045 |  |  | 62,822 |
