(2) | Income Per Common Share
Basic income per common share amounts are calculated using the weighted-average number of common shares outstanding for the period. Diluted income per common share amounts are calculated using the weighted-average number of common shares outstanding for the period and include the dilutive impact of exercise of stock options as well as assumed lapse of restrictions on restricted stock awards and shares currently available for purchase under the Company's Employee Stock Purchase Plan, using the treasury stock method. Performance-based restricted stock units are considered contingently issuable shares for diluted income per common share purposes and the dilutive impact, if any, is not included in the weighted-average shares until the performance conditions are met. The following table reconciles net income and the weighted average common shares outstanding used in the computations of basic and diluted income per common share (in thousands, except for share and per share data):
| Fiscal Year
| 2017 |  | 2016 |  | 2015
Numerator: |  |  |  |  |
Net income | $ | 102,451 |  |  | $ | 71,840 |  |  | $ | 57,680 |
Denominator: |  |  |  |  |
Weighted average common shares outstanding - basic | 55,208,246 |  |  | 54,845,708 |  |  | 54,513,622 |
Dilutive impact of options, restricted stock units, and employee stock purchase plan | 353,226 |  |  | 283,162 |  |  | 279,679 |
Weighted average common shares outstanding - diluted | 55,561,472 |  |  | 55,128,870 |  |  | 54,793,301 |
Per common share: |  |  |  |  |
Basic income per common share | $ | 1.86 |  |  | $ | 1.31 |  |  | $ | 1.06 |
Diluted income per common share | $ | 1.84 |  |  | $ | 1.30 |  |  | $ | 1.05 |
The effects of the assumed exercise of stock options outstanding as of February 3, 2018, January 28, 2017 and January 30, 2016 for 66,624, 164,440 and 710,153 shares of common stock, respectively, were excluded from the fiscal 2017, fiscal 2016 and fiscal 2015 calculation of diluted income per common share as their impact would have been anti-dilutive. The effects of non-vested restricted stock units outstanding as of February 3, 2018, January 28, 2017 and January 30, 2016 for 13,323, 3,600 and 6,500 shares of common stock, respectively, were excluded from the fiscal 2017, fiscal 2016 and fiscal 2015 calculation of diluted income per common share as their impact would have been anti-dilutive. The aforementioned excluded shares do not reflect the impact of any incremental repurchases under the treasury stock method.
