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 March 31,				Six Months Ended March 31,
	2015		2016		2015		2016
Weighted average common shares outstanding used in calculating basic income per share		24,544,272		24,154,397		24,409,969		24,183,926
Effect of dilutive options and non-vested restricted stock awards		721,585		542,484		695,293		515,675
Weighted average common and common equivalent shares used in calculating diluted income per share		25,265,857		24,696,881		25,105,262		24,699,601

For the three months ended March 31, 2015 and 2016, there were 1,361,973 and 1,246,371 weighted average shares related to options outstanding, respectively, that were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive. For the six months ended March 31, 2015 and 2016, there were 1,472,001 and 1,223,292 weighted average shares related to options outstanding, respectively, that were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of our common stock, and therefore, would have an anti-dilutive effect.
