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				Six Months Ended
	March 31,				March 31,
	2017		2018		2017		2018
Weighted average common shares outstanding used in calculating basic income per share		24,293,764		22,173,194		24,271,880		22,079,065
Effect of dilutive options and non-vested restricted stock awards		822,595		767,400		747,990		746,533
Weighted average common and common equivalent shares used in calculating diluted income per share		25,116,359		22,940,594		25,019,870		22,825,598

For the three months ended March 31, 2017 and 2018, there were 7,417 and 0 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 six months ended March 31, 2017 and 2018, there were 15,918 and 0 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.
