Earnings Per Share

Earnings Per Share

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

(Shares in millions)	Six months ended June 30		Three months ended June 30
	2012	2011	2012	2011
Weighted average shares outstanding	751.8	741.7	753.5	743.0
Participating securities	2.4	2.5	2.4	2.5
Basic weighted average shares outstanding	754.2	744.2	755.9	745.5
Dilutive potential common shares	6.5	6.6	6.1	7.1
Diluted weighted average shares outstanding	760.7	750.8	762.0	752.6

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.
