Weighted Average Shares Outstanding [Abstract]

Weighted Average Shares Outstanding

NOTE 4. WEIGHTED AVERAGE SHARES OUTSTANDING

Below is a reconciliation of basic to diluted shares outstanding:

	Three Months Ended March 31,
	2012		2011
Basic		223.4		228.9
Dilutive effect of shares issuable under stock-based compensation plans		4.0		2.5
Diluted		227.4		231.4
Anti-dilutive options to purchase common shares and restricted stock excluded from the table above		7.0		13.7

The calculation of diluted EPS requires certain assumptions regarding the use of both cash proceeds and assumed proceeds that would be received upon the exercise of stock options and vesting of restricted stock outstanding as of March 31, 2012 and 2011. These assumed proceeds include Excess Tax Benefits and any unrecognized compensation of the awards.
