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 July 31,				Six Months Ended July 31,
(in thousands)	2014		2013		2014		2013
Net earnings for basic and diluted EPS	$	124,120	$	106,781	$	249,729	$	190,358
Weighted-average shares for basic EPS	129,252		127,826		129,093		127,572
Incremental shares based upon the assumed exercise of stock options and unvested restricted stock units	656		945		758		1,034
Weighted-average shares for diluted EPS	129,908		128,771		129,851		128,606

For the three months ended July 31, 2014 and 2013, there were 347,000 and 412,000 stock options and restricted stock units excluded from the computations of earnings per diluted share due to their antidilutive effect. For the six months ended July 31, 2014 and 2013, there were 336,000 and 589,000 stock options and restricted stock units excluded from the computations of earnings per diluted share due to their antidilutive effect.
