The following table presents shares used in the calculation of basic and diluted net income per share:

	Three Months Ended				Six Months Ended
	March 31,				March 31,
	2018		2019		2018		2019
Weighted average common shares outstanding used in calculating basic income per share		22,173,194		22,836,571		22,079,065		22,807,756
Effect of dilutive options and non-vested restricted stock awards		767,400		581,117		746,533		601,117

For the three months ended March 31, 2018 and 2019, there were no weighted average shares related to options outstanding and non-vested restricted stock awards and 5,082 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, 2018 and 2019, 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.
