|  | Three Months Ended |
|  | April 30, |
|  | 2022 |  |  | 2021 |
Basic weighted-average common shares outstanding |  |  | 95,479,927 |  |  |  | 98,108,245 |
Effect of dilutive options, performance stock units and restricted stock units |  |  | 867,284 |  |  |  | 1,213,975 |
Diluted weighted-average shares outstanding |  |  | 96,347,211 |  |  |  | 99,322,220 |
For the three months ended April 30, 2022 and 2021, awards to purchase 200,000 common shares ranging in price from $28.47 to $46.42 and 200,000 common shares ranging in price from $35.85 to $46.42, respectively, 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 April 30, 2022 and April 30, 2021, were 197,501 and 161,254 performance-based equity awards, respectively, because they did not meet the required performance criteria.
