Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

EARNINGS PER SHARE

Basic earnings per share ("EPS") is computed as net earnings divided by the weighted-average number of common shares outstanding for the period. Diluted EPS includes the dilutive effect of the assumed exercise of stock options and unvested restricted stock units.

The following table summarizes the reconciliation of the numerators and denominators for the basic and diluted EPS computations:

	Three Months Ended April 30,
(in millions)	2015		2014
Net earnings for basic and diluted EPS	$	104.9	$	125.6
Weighted-average shares for basic EPS	129.2		128.9
Incremental shares based upon the assumed exercise of stock options and unvested restricted stock units	0.6		0.9
Weighted-average shares for diluted EPS	129.8		129.8

For the three months ended April 30, 2015 and 2014, there were 0.7 million and 0.3 million stock options and restricted stock units excluded from the computations of earnings per diluted share due to their antidilutive effect.
