Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

A reconciliation of basic and diluted shares follows (in thousands):

	Three months ended March 31,
	2015	2014
Average common shares outstanding	124,294	123,707
Effect of dilutive securities - share-based compensation	806	970
Average shares for diluted computations	125,100	124,677

There were no adjustments to net income required for purposes of computing diluted earnings per share.

Share options, appreciation rights and restricted share units granted under share-based compensation plans are antidilutive and excluded from diluted earnings per share when the hypothetical number of shares that could be repurchased under the treasury stock method exceeds the number of shares to be exercised.  Antidilutive shares, which could potentially dilute earnings per share in the future, are set forth below (in thousands):

	Three months ended March 31,
	2015	2014
Share options and appreciation rights	1,456	1,108
Restricted share units	1,533	—
Total potentially dilutive shares	2,989	1,108
