2.            Earnings Per Share (in thousands, except per share data)

A reconciliation of the basic and diluted earnings per share is as follows:

		Three months ended								Six months ended
		December 31,								December 31,
		2011				2010				2011				2010
Weighted average common shares outstanding – basic			22,248				22,051				22,233				22,054
Dilutive effect of stock options and unvested restricted stock units			449				518				454				509
Weighted average common shares outstanding – diluted			22,697				22,569				22,687				22,563
Net income		$	5,448			$	2,858			$	10,820			$	7,279
Earnings per common share
Diluted		$	0.24			$	0.13			$	0.48			$	0.32
Basic		$	0.24			$	0.13			$	0.49			$	0.33

Certain shares of common stock were excluded from the computation of diluted earnings per share because the options exercise prices were greater than the average market price of the common shares, and therefore, the effect would be anti-dilutive. A summary of those options follows:

		Three months ended								Six months ended
		December 31,								December 31,
		2011				2010				2011				2010
Number of anti-dilutive shares			811				5				813				125
