Earnings Per Share [Abstract] 
Earnings Per Share
Note 9 - 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 includes the dilutive effect of share options using the treasury stock method and excludes non-vested shares.
 
 
 
 
    The following table is a reconciliation of net income attributable to Ensco shares used in our basic and diluted EPS computations for the three-month and nine-month periods ended September 30, 2011 and 2010 (in millions):
