Net Earnings Per Share [Abstract]

Earnings Per Share

13. Net Earnings Per Share

A reconciliation of the number of weighted shares used to compute basic and diluted net earnings per share for the three months ended March 31, 2012 and 2011 are illustrated below:

	Three Months Ended
	March 31,
	2012		2011
Weighted average common shares outstanding for basic EPS		31,399,249		30,375,003
Effect of dilutive securities: employee stock options		412,883		424,832
Adjusted weighted average common shares outstanding for diluted EPS		31,812,132		30,799,835

Weighted options to purchase a total of 400,529 and 43,967 shares of the Company's common stock for the three months ended March 31, 2012 and 2011, respectively, were excluded from the calculations of fully diluted earnings per share, in each case because the effect on fully diluted earnings per share for the period was antidilutive.
