Earnings Per Share [Abstract] |
Net Income Per Common Share | (5) Net Income Per Common Share Basic net income per share is calculated by dividing net income by the weighted average number of shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average number of shares and, if dilutive, common equivalent shares, determined using the treasury stock method for stock options, restricted stock awards and restricted stock units outstanding during the period. A reconciliation of the shares used in calculating basic and diluted net income per share is as follows:
|  | Three Months Ended |
|  | April 30, 2016 |  |  | May 2, 2015 |
Weighted Average Common Shares Outstanding—Basic |  |  | 7,357,588 |  |  |  | 7,280,246 |
Effect of Dilutive Options and Restricted Stock Units |  |  | 166,661 |  |  |  | 173,936 |
Weighted Average Common Shares Outstanding—Diluted |  |  | 7,524,249 |  |  |  | 7,454,182 |
For the three months ended April 30, 2016 and May 2, 2015 the diluted per share amounts do not reflect common equivalent shares outstanding of 431,133 and 244,100, respectively, because their effect would have been anti-dilutive.
