15. 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 for the fiscal years ended September 30,

	2015		2016		2017
Weighted average common shares outstanding used in calculating basic income per share		24,466,243		24,203,947		23,966,611
Effect of dilutive options and non-vested restricted stock awards		636,046		616,900		712,189
Weighted average common and common equivalent shares used in calculating diluted income per share		25,102,289		24,820,847		24,678,800

During the fiscal years ended September 30, 2015, 2016, and 2017 there were 1,553,207, 140,521, and 18,526 weighted average shares of 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.
