Weighted average common shares outstanding used in calculating basic net income per share |  | 21,853,557 |  |  |  | 22,299,599 |  |  |  | 21,804,326 |  |  |  | 22,247,587 |
Effect of dilutive options and non-vested restricted stock awards |  | 460,705 |  |  |  | 699,630 |  |  |  | 463,857 |  |  |  | 656,253 |

For the three months ended March 31, 2023 and 2024, there were 14,204 and 5,000 weighted average shares of options outstanding and non-vested restricted stock outstanding, respectively, that were not included in the computation of diluted net income per share because the options’ exercise prices or non-vested restricted stock prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive. For the six months ended March 31, 2023 and 2024, there were 102,568 and 5,000 weighted average shares of options outstanding and non-vested restricted stock outstanding, respectively, that were not included in the computation of diluted net income per share because the options’ exercise prices or non-vested restricted stock prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive.
