Earnings Per Share [Abstract] |
Net Income (Loss) per Common Share | 11. Net Income (Loss) per Common Share The following is a reconciliation of the weighted-average common shares outstanding used for the computation of basic and diluted net income (loss) per common share:
|  | Three Months Ended |  |  | Nine Months Ended |
|  | October 31, |  |  | October 31, |
|  | 2020 |  |  | 2019 |  |  | 2020 |  |  | 2019 |
Basic weighted-average common shares outstanding |  |  | 97,784,661 |  |  |  | 97,972,864 |  |  |  | 97,823,948 |  |  |  | 100,458,726 |
Effect of dilutive options, performance stock units and restricted stock units |  |  | 798,371 |  |  |  | 655,305 |  |  |  | — |  |  |  | 688,299 |
Diluted weighted-average shares outstanding |  |  | 98,583,032 |  |  |  | 98,628,169 |  |  |  | 97,823,948 |  |  |  | 101,147,025 |
For the three months ended October 31, 2020 and 2019, awards to purchase 460,000 common shares ranging in price from $23.74 to $46.42 and 415,000 common shares ranging in price from $28.47 to $46.42, respectively, were excluded from the calculation of diluted net income per common share because the impact would be anti-dilutive. As a result of the net loss for the nine months ended October 31, 2020, all share-based awards have been excluded from the calculation of diluted loss per share and therefore there was no difference in the weighted average number of common shares for basic and diluted loss per share as the effect of all potentially dilutive shares outstanding was anti-dilutive. For nine months ended October 31, 2019, awards to purchase 405,000 common shares ranging in price from $28.47 to $46.42 were excluded from the calculation of diluted net income per common share because the impact would be anti-dilutive. Excluded from the calculation of diluted net income per common share as of October 31, 2020 and 2019, were 271,501 and 370,633 performance-based equity awards, respectively, because they did not meet the required performance criteria.
