Net Income Per Share | 3 Months Ended
--- | ---
Jul. 29, 2012
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) |  | July 29, 2012 |  |  | July 31, 2011 |
Weighted average common shares outstanding, basic |  |  | 12,551 |  |  |  | 13,061 |
Dilutive effect of stock-based compensation |  |  | 160 |  |  |  | 144 |
Weighted average common shares outstanding, diluted |  |  | 12,711 |  |  |  | 13,205 |
All options to purchase shares of common stock were included in the computation of diluted net income for the three months ended July 29, 2012, as the exercise price of the options was less than the average market price of the common shares. Options to purchase 24,750 shares of common stock were not included in the computation of diluted net income per share for the three months ended July 31, 2011, as the exercise price of the options was greater than the average market price of the common shares. The computations of basic net income per share did not include 123,335 and 185,000 shares of time vested restricted common stock as these shares were unvested for the three months ending July 29, 2012 and July 31, 2011, respectively.
