Earnings Per Share [Abstract]

Income (Loss) 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. For the three months ended June 30, 2015, and the three and six months ended June 30, 2014, differences between basic and diluted weighted average common shares outstanding resulted from the dilutive effect of awards granted under our stock incentive plans.

Excluded from the computation of diluted income per share are options to purchase five million shares of common stock that were outstanding during the three months ended June 30, 2015 and options to purchase one million shares of common stock that were outstanding during the six months ended June 30, 2014. These options were outstanding but were excluded because they were antidilutive, as the option exercise price was greater than the average market price of the common shares. There were no antidilutive shares outstanding for the three months ended June 30, 2014.

For the six months endedJune 30, 2015, we incurred losses from continuing operations attributable to company shareholders and accordingly excluded all potentially dilutive securities from the determination of diluted loss per share as their impact was antidilutive. Antidilutive securities for the six months ended June 30, 2015 totaled nine million shares, which includes options to purchase seven million shares of common stock where the exercise price was greater than the average market price and options to purchase two million shares of common stock which ordinarily would be considered dilutive if not for us being in a net loss position for the six months ended June 30, 2015.
