Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share We compute basic and diluted earnings per share ("EPS") in accordance with the two-class method. Net income attributable to Ensco used in our computations of basic and diluted EPS is adjusted to exclude net income allocated to non-vested shares granted to our employees and non-employee directors. Weighted-average shares outstanding used in our computation of diluted EPS is calculated using the treasury stock method and excludes non-vested shares. The following table is a reconciliation of income from continuing operations attributable to Ensco shares used in our basic and diluted EPS computations for the quarter s ended March 31, 2015 and 2014 (in millions):

Income from continuing operations attributable to Ensco | $ | 324.9 |  |  | $ | 294.6 |
Income from continuing operations allocated to non-vested share awards | (3.7 | ) |  | (3.0 | )
Income from continuing operations attributable to Ensco shares | $ | 321.2 |  |  | $ | 291.6 |
