| Earnings Per Share [Abstract] | |
| Earnings Per Share | Earnings per Share Basic earnings per share is computed by dividing net income by the number of weighted average common shares outstanding during the reporting period. Diluted earnings per share is calculated to give effect to all potentially dilutive common shares that were outstanding during the reporting period. The effect of dilutive securities excludes certain stock options, restricted stock units and convertible debt-related shares because the inclusion of these securities was antidilutive to earnings per share. For the three and nine months ended September 30, 2013 and 2012, no common stock equivalents were included in the computation of the diluted loss per share because we reported a net loss. Accordingly, 2.1 million shares for the three and nine months ended September 30, 2013 and 1.9 million shares for the three and nine months ended September 30, 2012 related to stock-based compensation awards were excluded from the diluted loss per share calculation. In addition, 3.0 million common shares related to the convertible notes were excluded from the diluted loss per share calculation for all periods. |
