Earnings Per Share [Abstract] |
Net Income Per Share | 11. Net Income Per Share Basic net income per share is computed using the weighted-average number of shares outstanding during the period. Diluted net income per share uses the weighted-average number of shares outstanding during the period plus the dilutive effect of stock-based compensation calculated using the treasury stock method. Weighted average shares used in the computation of basic and diluted net income per share follows:
|  | Three months ended |
(amounts in thousands) |  | January 31, 2016 |  |  | February 1, 2015 |
Weighted average common shares outstanding, basic |  |  | 12,331 |  |  |  | 12,219 |
Dilutive effect of stock-based compensation |  |  | 155 |  |  |  | 198 |
Weighted average common shares outstanding, diluted |  |  | 12,486 |  |  |  | 12,417 |
All options to purchase shares of common stock were included in the computation of diluted net income for the three months ended January 31, 2016 and February 1, 2015, as the exercise price of the options was less than the average market price of the common shares.
|  | Nine months ended |
(amounts in thousands) |  | January 31, 2016 |  |  | February 1, 2015 |
Weighted average common shares outstanding, basic |  |  | 12,317 |  |  |  | 12,216 |

Weighted average common shares outstanding, diluted |  |  | 12,488 |  |  |  | 12,410 |
All options to purchase shares of common stock were included in the computation of diluted net income for the nine months ended January 31, 2016 and February 1, 2015, as the exercise price of the options was less than the average market price of the common shares.
