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 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 September 30,				Nine Months Ended September 30,
(in thousands)	2012		2011		2012		2011
Weighted-average number of shares of common stock for calculating basic earnings per share		24,785		24,362		24,730		24,320
Effect of potentially dilutive securities from equity-based compensation		321		357		403		382
Weighted-average number of shares of common stock for calculating diluted earnings per share		25,106		24,719		25,133		24,702

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