Earnings Per Share

EARNINGS PER SHARE

We use the two-class method to compute basic and diluted EPS. Earnings for the period are allocated pro-rata between the common shareholders and the participating securities. Our only participating securities were related to the Share Repurchase Agreements. The numerator for basic and diluted EPS is net earnings for common stockholders. The denominator for basic EPS is the weighted-average number of shares outstanding during the period. The denominator for diluted EPS also includes the weighted average number of additional common shares that would have been outstanding if the dilutive potential common shares had been issued, unless the shares are anti-dilutive, and excludes shares subject to forward contracts.

The following is a reconciliation of the numerator and denominator for the basic and diluted EPS computations:

Basic weighted average number of shares outstanding attributable to common stockholders	358.5		374.1			420.8			425.7
Dilutive impact of share-based awards	1.8		1.5			1.2			1.2
Diluted weighted average number of shares outstanding	360.3		375.6			422.0			426.9
Basic net earnings per share	$	2.79	$	2.69		$	0.80		$	4.44
Diluted net earnings per share	$	2.78	$	2.68		$	0.80		$	4.42

A total of 2.2 million shares for 2015, 2.1 million shares for 2014, 1.4 million shares for the seven months ended December 31, 2013, and 0.7 million shares for fiscal 2013 of common stock subject to issuance upon exercise of stock awards have been excluded from the calculation of diluted EPS because the effect would be anti-dilutive.
