Earnings Per Share [Abstract] |
Loss Per Share | 9. Loss Per Share Basic loss per share is computed in accordance with ASC 260, Earnings per Share , based on weighted average outstanding common shares. Diluted loss per share is computed based on basic weighted average outstanding common shares adjusted for the dilutive effect of stock options and RSUs. The following table reconciles the weighted average share amounts used to compute both basic and diluted loss per share (in thousands):
|  | Three Months Ended March 31, |
|  | 2019 |  |  | 2018 |
Weighted average shares outstanding: |  |  |  |  |  |  |  |
Basic weighted average shares outstanding |  |  | 116,090 |  |  |  | 115,642 |
Add: Dilutive effect of stock options and RSUs |  |  | — |  |  |  | — |
Diluted weighted average shares outstanding |  |  | 116,090 |  |  |  | 115,642 |
The diluted loss per share computation excludes 7.4 million and 8.6 million options to purchase shares, RSUs, and contingently issuable shares during the three months ended March 31, 2019 and 2018, respectively, as their effect would be anti-dilutive. Common stock outstanding as of March 31, 2019, and December 31, 2018, was 116,530,435 and 116,123,361, respectively.
