Earnings Per Share

We compute basic and diluted earnings per share ("EPS") in accordance with the two-class method. Net (loss)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 net (loss) income attributable to Ensco shares used in our basic and diluted EPS computations for the three-month and six-month periods ended June 30, 2014 and 2013 (in millions):



	Three Months Ended June 30,						Six Months Ended June 30,
	2014			2013			2014			2013
Net (loss) income attributable to Ensco	$	(1,172.7	)	$	360.9		$	(880.2	)	$	678.0
Net income allocated to non-vested share awards	(2.1		)	(3.9		)	(3.9		)	(7.2		)
Net (loss) income attributable to Ensco shares	$	(1,174.8	)	$	357.0		$	(884.1	)	$	670.8

Net income allocated to non-vested share awards during the three-month and six-month periods ended June 30, 2014 represented dividends paid on non-vested share awards of $2.1 million and $3.9 million, respectively, and reduced net (loss) income from continuing operations attributable to Ensco shares in our basic and diluted EPS computations.

The following table is a reconciliation of the weighted-average shares used in our basic and diluted EPS computations for the three-month and six-month periods ended June 30, 2014 and 2013 (in millions):



	Three Months Ended June 30,		Six Months Ended June 30,
	2014	2013	2014	2013

Weighted-average shares - diluted	231.5	231.0	231.4	230.8
