Earnings Per Share

Earnings Per Share

9. EARNINGS PER SHARE

Basic earnings per share ("EPS") is computed by dividing net earnings (the numerator) by the weighted average number of Common Shares outstanding during each period (the denominator). Diluted EPS is similar to the computation for Basic EPS, except that the denominator is increased by the dilutive effect of vested and nonvested stock options, restricted shares and restricted share units computed using the treasury stock method. The total number of Common Shares issued, less the Common Shares held in treasury, is used to determine the Common Shares outstanding.

The following table reconciles the number of Common Shares used to compute Basic EPS and Diluted EPS for the three months ended September 30, 2011 and 2010:

	Three Months Ended September 30,
(in millions)	2011		2010
Weighted-average Common Shares–basic		344.8		348.9
Effect of dilutive securities:
Employee stock options, restricted shares and restricted share units		4.6		3.0
Weighted-average Common Shares–diluted		349.4		351.9

The following table presents the number of potentially dilutive securities that were anti-dilutive for the three months ended September 30, 2011 and 2010:

	Three Months Ended September 30,
(in millions)	2011		2010
Anti-dilutive securities		9.7		14.9
