Earnings Per Share [Abstract]

EARNINGS PER SHARE

NOTE 2.    EARNINGS PER SHARE

Basic earnings per share (“EPS”) is computed as net income divided by the weighted-average number of shares of common stock outstanding for the period. Diluted EPS is computed as net income divided by the weighted-average number of shares outstanding of common stock and common stock equivalents for the period, including the dilutive effects of stock options and other potentially dilutive securities. Common stock equivalents result from the number of dilutive options and are computed using the treasury stock method and the average share price for the reported period. The table below presents the weighted-average number of shares of common stock used to calculate basic and diluted earnings per share:

	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands)	2012		2011		2012		2011
Weighted-average number of shares of common stock for calculating basic earnings per share		24,765		24,340		24,702		24,299
Effect of potentially dilutive securities from equity-based compensation		384		402		437		401
Weighted-average number of shares of common stock for calculating diluted earnings per share		25,149		24,742		25,139		24,700

The following securities were not included in the computation of diluted earnings per share as their effect would have been anti-dilutive:
