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,
	2016		2017		2016		2017
Weighted average common shares outstanding used in calculating basic income per share		24,154,397		24,293,764		24,183,926		24,271,880
Effect of dilutive options and non-vested restricted stock awards		604,429		822,595		566,812		747,990
Weighted average common and common equivalent shares used in calculating diluted income per share		24,758,826		25,116,359		24,750,738		25,019,870

For the three months ended March 31, 2016 and March 31, 2017, there were 1,246,371 and 7,417 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. For the six months ended March 31, 2016 and March 31, 2017, there were 1,223,292 and 15,918 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.
