Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

Earnings per share

Basic earnings per share is based on the average number of common shares outstanding during the period. Diluted earnings per share is based on the average number of shares used for the basic earnings per share calculation, adjusted for the dilutive effect of stock options and restricted stock equivalents.

The following table sets forth the computation of basic and diluted earnings per share for the quarter ended December 31, 2012 and 2011, respectively.

(in millions, except per share data)	Quarter Ended December 31,
	2012		2011
Numerator:
Net earnings for basic and dilutive earnings per share	$	129.8	$	143.8
Denominator:
Weighted-average shares - basic	61.8		66.2
Effect of dilutive securities:
Stock options	0.1		0.2
Restricted stock equivalents	0.7		0.5
Total dilutive securities	0.8		0.7
Weighted-average shares - diluted	62.6		66.9
Basic net earnings per share	$	2.10	$	2.17
Diluted net earnings per share	$	2.07	$	2.15

At December 31, 2012 and 2011, approximately 0.4 and 0.6 of the Company’s outstanding RSEs and stock options were not included in the diluted net earnings per share calculation, for each period, because to do so would have been anti-dilutive. In the event that potentially dilutive securities are anti-dilutive on net earnings per share (i.e., have the effect of increasing EPS because the exercise price is higher than the current share price), the impact of the potentially dilutive securities is not included in the computation.
