13. NET INCOME PER SHARE:

The following is a reconciliation of the shares used in the denominator for calculating basic and diluted net income per share:

	Three Months Ended				Nine Months Ended
	June 30,				June 30,
	2017		2018		2017		2018
Weighted average common shares outstanding used in    calculating basic income per share		24,336,777		22,399,079		24,293,512		22,185,736
Effect of dilutive options and non-vested restricted stock    awards		758,621		783,467		751,534		758,845
Weighted average common and common equivalent shares    used in calculating diluted income per share		25,095,398		23,182,546		25,045,046		22,944,581

For the three months ended June 30, 2017 and 2018, there were 7,418 and 110 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 nine months ended June 30, 2017 and 2018, there were 18,084 and 1,193 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.
