Weighted average common shares outstanding used in calculating basic net income per share		22,132,915		21,524,315		22,100,190		21,761,811

For the three months ended June 30, 2021 and 2022, there were no weighted average shares of options and non-vested restricted stock outstanding and 89,518 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 nine months ended June 30, 2021 and 2022, there were 578 and 71,455 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.
