2.	Shareholders’ Equity and Earnings per Share

Basic earnings per share (“EPS”) is calculated by dividing earnings available to common shareholders by the weighted average number of common shares outstanding, including participating securities outstanding. Diluted EPS is similar to basic EPS, but adjusts for the effect of the potential issuance of common shares. We include all unvested stock awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, in our basic and diluted EPS number of shares outstanding.

The following table presents information about basic and diluted weighted average shares outstanding:

( in thousands )	Three months ended				Nine months ended
	September 30,				September 30,
	2015		2014			2015	2014
Weighted average shares outstanding:
Basic		129,177		140,738		129,817	142,786
Dilutive effect of equity awards		527		890		617	917
Diluted weighted average shares outstanding		129,704		141,628		130,434	143,703
Anti-dilutive share awards		1,193		288		752	301

For the three and nine months ended September 30, 2015 and 2014, we had stock options that were anti-dilutive and, accordingly, were not included in the computation of diluted weighted average shares outstanding.
