Notes to Financial Statements [Abstract] |
Earnings Per Share | Earnings Per Share Basic earnings per share is computed based on the weighted-average number of common shares and stock rights outstanding. Diluted earnings per share is computed based on the weighted-average number of common shares and stock rights outstanding plus the dilutive effects of equity awards, convertible notes and escrow shares. Potential common shares that would increase earnings per share amounts or decrease loss per share amounts are antidilutive and are therefore excluded from diluted earnings per share calculations. Antidilutive potential common shares that could dilute basic earnings per share in the future were 290.9 million for the second quarter and first six months of 2012, and 166.0 million and 167.5 million for the second quarter and first six months of 2011, respectively.
