Earnings Per Share [Abstract]

Income per Share

Income per Share

Basic income or loss per share is based on the weighted average number of common shares outstanding during the period. Diluted income per share includes additional common shares that would have been outstanding if potential common shares with a dilutive effect had been issued. Antidilutive securities represent potentially dilutive securities which are excluded from the computation of diluted income or loss per share as their impact was antidilutive.

A reconciliation of the number of shares used for the basic and diluted income per share computations is as follows:

Dilutive effect of awards granted under our stock incentive plans	1	3	4
Diluted weighted average common shares outstanding	883	902	908
Antidilutive shares:
Options with exercise price greater than the average market price	10	12	15
Total antidilutive shares	10	12	15
