|  | 2013 |  |  | 2014 |  |  | 2015 |
Weighted average common shares outstanding used in calculating basic income per share |  |  | 23,253,992 |  |  |  | 23,916,238 |  |  |  | 24,466,243 |
Effect of dilutive options and non-vested restricted stock awards |  |  | 749,736 |  |  |  | 739,024 |  |  |  | 636,046 |
Weighted average common and common equivalent shares used in calculating diluted income per share |  |  | 24,003,728 |  |  |  | 24,655,262 |  |  |  | 25,102,289 |
During the fiscal years ended September 30, 2013, 2014, and 2015 there were 1,728,042, 1,144,600, and 1,553,207 weighted average shares of options outstanding, respectively, that were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive.
