Earnings Per Share [Abstract] |
Earnings Per Share | 10. Earnings Per Share Basic earnings (loss) per share is computed as net earnings (loss) divided by the basic weighted average common shares outstanding of 35.4 million and 35.0 million shares for the three months ended March 31, 2018 and 2017, respectively. The calculation of diluted earnings (loss) per share includes the effect of any dilutive equity incentive instruments. The Company uses the treasury stock method to calculate the effect of outstanding dilutive equity incentive instruments, which requires the Company to compute total proceeds as the sum of the amount the employee must pay upon exercise of the award and the amount of unearned stock-based compensation costs attributable to future services. Equity incentive instruments for which the total employee proceeds from exercise exceed the average fair value of the same equity incentive instrument over the period have an anti-dilutive effect on earnings per share during periods with net earnings, and accordingly, the Company excludes them from the calculation. Due to the net loss incurred during the three months ended March 31, 2018 and 2017, the assumed exercise of all equity incentive instruments was anti-dilutive and, therefore, not included in the diluted loss per share calculation for those periods. The following is a reconciliation of the average shares outstanding used to compute basic and diluted earnings per share:
|  | Three Months Ended March 31, |
|  | 2018 |  |  | 2017 |
Basic weighted average common shares outstanding |  |  | 35,367,340 |  |  |  | 35,020,428 |
Effect of dilutive securities |  |  | — |  |  |  | — |
Diluted weighted average common shares outstanding |  |  | 35,367,340 |  |  |  | 35,020,428 |
No cash dividends were paid during any of the three months ended March 31, 2018 and 2017.
