Earnings Per Share [Abstract]

Income Per Share

INCOME PER SHARE

Basic per share amounts were computed using the weighted average number of common shares outstanding. Diluted per share amounts were calculated using the number of basic weighted average shares outstanding increased by dilutive potential common shares related to stock-based awards, as determined by the treasury stock method. The weighted average numbers of shares outstanding used to compute income per share were as follows (in thousands):

	Three months ended March 31,
	2014	2013
Shares used to calculate basic income per share	31,172	30,947
Dilutive effect of outstanding options, performance stock units and restricted stock units	378	317
Shares used to calculate diluted income per share	31,550	31,264

The weighted average numbers of shares outstanding listed in the table below were anti-dilutive and excluded from the computation of diluted income per share, primarily because the average market price did not exceed the exercise price. These shares may be dilutive potential common shares in the future (in thousands):
