Earnings Per Share

Basic earnings per share (EPS) is computed by dividing reported net income by the weighted-average number of shares outstanding. Diluted EPS considers the potential dilution that could occur if common stock equivalents were exercised or converted into stock. The difference between the basic and diluted weighted-average equivalent shares with respect to the Company's EPS calculation is due entirely to the assumed exercise of stock options and the vesting of restricted stock and restricted stock units. The effect of 653 and 541 restricted stock units had no impact upon the years ended December 31, 2011, and 2010, because they were anti-dilutive to EPS. The dilutive effect of stock options and awards for each period reported is summarized below:

	2011		2010		2009
	(in thousands)
Basic weighted-average shares outstanding		19,684		19,375		15,433
Effect of potential exercise of stock options and unvested restricted stock and restricted stock units		244		251		481
Diluted weighted-average shares outstanding		19,928		19,626		15,914
