Net Income Per Share [Abstract]

Net Income Per Share

3.   Net Income Per Share

Basic net income per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding. Diluted net income per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding plus the effect of any dilutive stock options and restricted stock units using the treasury stock method and the net share settlement method for the convertible debt. During the three months ended March 31, 2012 and 2011, the average trading price of the Company's stock did not exceed the conversion price of the convertible debt, therefore there was no impact to the calculation of diluted shares.

The following is a summary of the number of shares entering into the computation of net income per common and potential common shares:

	Three Months Ended March 31,
	2012		2011
Weighted average basic number of shares outstanding		24,210,913		24,839,424
Dilutive stock options		117,413		219,839
Dilutive restricted stock units		32,124		70,661
Dilutive contingent convertible debt common shares		-		-
Number of shares used in fully diluted computations		24,360,450		25,129,924

Not included in the number of shares used in the fully diluted computation for the three months ended March 31, 2012 and 2011 are 209,795 and 93,062 shares, respectively, pertaining to restricted stock units as their impact would be anti-dilutive.
