Earnings Per Share [Abstract]

Earnings Per Share

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 July 31,				Six Months Ended July 31,
(in millions)	2019		2018		2019		2018
Net earnings for basic and diluted EPS	$	136.3	$	144.7	$	261.5	$	287.0
Weighted-average shares for basic EPS	121.1		123.2		121.3		123.8
Incremental shares based upon the assumed exercise of stock options and unvested restricted stock units	0.3		0.8		0.3		0.7
Weighted-average shares for diluted EPS	121.4		124.0		121.6		124.5

For both the three and six months ended July 31, 2019, there were 1.7 million stock options and restricted stock units that were excluded from the computations of earnings per diluted share due to their antidilutive effect. For the three and six months ended July 31, 2018, there were 0.4 million and 0.7 million, respectively, stock options and restricted stock units that were excluded from the computations of earnings per diluted share due to their antidilutive effect.
