Earnings (Loss) per Share [Abstract] |
Earnings (Loss) per Share | Earnings (Loss) per Share We include restricted stock units for which no future service is required as a condition to the delivery of the underlying common stock in our calculation of weighted average shares outstanding. As we incurred a net loss for the year ended December 31, 2011, diluted loss per share for this period is computed on the same basis as basic loss per share, as the inclusion of any other potential shares outstanding would be anti-dilutive. Reconciliations of the amounts used in the basic and diluted earnings (loss) per common share computations for the years ended December 31, 2013, 2012 and 2011, are as follows (shares in thousands):
| 2013 |  | 2012 |  | 2011
Diluted weighted average shares calculation: |  |  |  |  |
Weighted average shares outstanding (basic) | 440,666 |  |  | 467,752 |  |  | 485,381 |
Share-based awards | 4,107 |  |  | 3,591 |  |  | — |
Weighted average shares outstanding (diluted) | 444,773 |  |  | 471,343 |  |  | 485,381 |
We excluded the following items from diluted earnings (loss) per common share for the years ended December 31, 2013, 2012 and 2011, because they were anti-dilutive (shares in thousands):
| 2013 |  | 2012 |  | 2011
Share-based awards | 5,062 |  |  | 10,302 |  |  | 15,260 |
