Earnings Per Share [Abstract] | |
Income (Loss) per Share | Income per Share Basic income 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. Differences between basic and diluted weighted average common shares outstanding for all periods presented 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 one million shares of common stock that were outstanding during the six months ended June 30, 2014, and options to purchase six million and five million shares of common stock that were outstanding during the three and six months ended June 30, 2013, respectively. 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. |
