3 Months Ended

15.	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,
	2018		2019
Weighted average common shares outstanding used in calculating basic income per share		22,779,567		21,453,914
Effect of dilutive options and non-vested restricted stock awards		621,118		436,151
Weighted average common and common equivalent shares used in calculating diluted income per share		23,400,685		21,890,065

For the three months ended December 31, 2018, there were no weighted average shares related to options outstanding and non-vested restricted stock awards, respectively, that were not included in the computation of diluted income per share because the options’ exercise prices or assumed proceeds per share were greater than the average market price of our common stock, and

therefore, would have an anti-dilutive effect. For the three months ended December 31, 2019, there were 32,366 shares related to options outstanding and non-vested restricted stock awards, respectively, that were not included in the computation of diluted income per share because the options’ exercise prices or assumed proceeds per share were greater than the average market price of our common stock, and therefore, would have an anti-dilutive effect.
