3 Months Ended

16.	NET INCOME PER SHARE:

The following table presents shares used in the calculation of basic and diluted net income per share:

	Three Months Ended
	December 31,
	2020		2021
Weighted average common shares outstanding used in calculating basic net income per share		22,025,898		21,899,264
Effect of dilutive options and non-vested restricted stock awards		719,227		764,430
Weighted average common and common equivalent shares used in calculating diluted net income per share		22,745,125		22,663,694

For the three months ended December 31, 2020 and 2021, there were 30,807 and 328,185 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.
