Earnings Per Share [Abstract] |
Net (Loss) Income per Common Share | 11. Net (Loss) Income per Common Share The following is a reconciliation of the weighted-average common shares outstanding used for the computation of basic and diluted net (loss) income per common share:
|  | Three Months Ended |
|  | April 30, |
|  | 2020 |  |  | 2019 |
Basic weighted-average common shares outstanding |  |  | 97,910,314 |  |  |  | 104,437,460 |
Effect of dilutive options, stock appreciation rights, performance stock units and restricted stock units |  |  | — |  |  |  | 902,688 |
Diluted weighted-average shares outstanding |  |  | 97,910,314 |  |  |  | 105,340,148 |
As a result of the net loss for the three months ended April 30, 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 the three months ended April 30, 2019, awards to purchase 380,000 common shares ranging in price from $35.85 to $46.42 were excluded from the calculation of diluted net income per common share because the impact would be anti-dilutive. Also excluded from the calculation of diluted net income per common share as of April 30, 2019, were 711,418 performance-based equity awards because they did not meet the required performance criteria.
