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 April 30,
(in millions)	2020			2019
Net (loss) earnings for basic and diluted EPS	$	(64.6	)	$	125.2
Weighted-average shares for basic EPS	121.2			121.4
Incremental shares based upon the assumed exercise of stock options and unvested restricted stock units	—			0.5
Weighted-average shares for diluted EPS	121.2			121.9

For the three months ended April 30, 2020, stock options and restricted stock units were excluded from the computation of diluted earnings per share due to the net loss incurred during the period. For the three months ended April 30, 2019, there were 1.7 million stock options and restricted stock units that were excluded from the computation of earnings per diluted share due to their antidilutive effect.
