Earnings Per Share

Note 4 – Earnings Per Share

The weighted-average number of shares outstanding used to compute earnings per share are as follows:

(Shares in millions) Years ended December 31,	2011		2010		2009
Weighted average shares outstanding		744.1		735.0		705.9
Participating securities		2.5		3.1		3.7
Basic weighted average shares outstanding		746.6		738.1		709.6
Dilutive potential common shares		6.5		6.2		3.8
Diluted weighted average shares outstanding		753.1		744.3		713.4

Basic earnings per share is calculated by the sum of (1) net earnings less declared dividends and dividend equivalents related to share-based compensation divided by the basic weighted average shares outstanding and (2) declared dividends and dividend equivalents related to share-based compensation divided by the weighted average shares outstanding.

The weighted average number of shares outstanding, included in the table below, were excluded from the computation of diluted earnings per share because the average market price did not exceed the exercise/threshold price. However, these shares may be dilutive potential common shares in the future.
