	2021		2022		2021		2022
Weighted average common shares outstanding used in calculating basic net income per share		22,143,043		21,861,438		22,083,827		21,880,558
Effect of dilutive options and non-vested restricted stock awards		843,018		668,664		781,123		716,547

For the three months ended March 31, 2021 and 2022, there were no weighted average shares of options and non-vested restricted stock outstanding and 153,825 weighted average shares of options 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, 2021 and 2022, there were 104 and 63,924 weighted average shares of options 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.
