Income Per Share

INCOME PER SHARE

Basic Income Per Share was computed using the weighted average number of common shares outstanding. For the computation of Diluted Income Per Share, the number of basic weighted average shares outstanding was 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 September 30,		Nine months ended September 30,
	2013	2012	2013	2012
Shares used to calculate basic income per share	31,128	30,892	31,045	30,892
Dilutive effect of outstanding options and performance stock units	360	51	374	118
Shares used to calculate diluted income per share	31,488	30,943	31,419	31,010

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):

	Three months ended September 30,		Nine months ended September 30,
	2013	2012	2013	2012
Stock options	298	1,115	303	1,072
Performance stock units	84	130	17	47
