Net Loss Per Share |
Net Loss Per Share | NOTE 9. NET LOSS PER SHARE Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period, less shares subject to repurchase, and excludes any dilutive effects of stock-based awards and warrants. Diluted net loss per common share is computed giving effect to all potential dilutive common shares, including common stock issuable upon exercise of stock options, and unvested restricted common stock and stock units. As the Company had net losses for the three and nine months ended September 30, 2018 and 2017, all potential common shares were determined to be anti-dilutive. The following table sets forth the computation of net loss per common share (in thousands, except share and per share amounts):
|  | Three Months Ended |  | Nine Months Ended
|  | September 30, |  | September 30,
|  | 2018 |  | 2017 |  | 2018 |  | 2017
Numerator: |  |  |  |  |  |  |  |  |  |  |  |
Net loss |  | $ | (24,126) |  | $ | (20,724) |  | $ | (63,436) |  | $ | (74,453)
Denominator: |  |  |  |  |  |  |  |  |  |  |  |
Weighted average common shares outstanding - basic and diluted |  |  | 62,071,397 |  |  | 47,464,310 |  |  | 54,204,907 |  |  | 47,404,039
Net loss per share - basic and diluted |  | $ | (0.39) |  | $ | (0.44) |  | $ | (1.17) |  | $ | (1.57)
For the three and nine months ended September 30, 2018 the total number of securities that could potentially dilute basic net loss per share in the future that were not included in the computation of diluted net loss per share because the effect would have been antidilutive was 8.3 million and 8.1 million, respectively. For the three and nine months ended September 30, 2017, the total number of securities that could potentially dilute basic net loss per share in the future that were not included in the computation of diluted net loss per share because the effect would have been antidilutive was 7.0 million and 6.6 million, respectively.
