Earnings Per Share [Abstract] |
Net Income Per Common Share | (6) 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 28, 2018 |  |  | April 29, 2017 |
Weighted Average Common Shares Outstanding—Basic |  |  | 6,787,926 |  |  |  | 7,480,039 |
Effect of Dilutive Options and Restricted Stock Units |  |  | 128,229 |  |  |  | 135,507 |
Weighted Average Common Shares Outstanding—Diluted |  |  | 6,916,155 |  |  |  | 7,615,546 |
For the three months ended April 28, 2018 and April 29, 2017, the diluted per share amounts do not include common equivalent shares outstanding of 248,480 and 472,214, respectively, because their effect would have been anti-dilutive.
