Earnings Per Common Share

3 Months Ended

Jun. 30, 2017

Basic earnings per common share are computed by dividing net income by the weighted average number of common shares outstanding during the reporting period. Diluted earnings per common share are computed similar to basic earnings per common share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock.

The computations for basic and diluted earnings per common share are as follows:



	Quarter Ended June 30,
(In millions, except per share amounts)	2017			2016
Income from continuing operations	$	363		$	673
Net income attributable to noncontrolling interests	(56		)	(18		)
Income from continuing operations attributable to McKesson	307			655
Income (loss) from discontinued operations, net of tax	2			(113		)
Net income attributable to McKesson	$	309		$	542

Weighted average common shares outstanding:
Basic	211			225
Effect of dilutive securities:
Options to purchase common stock	1			1
Restricted stock units	1			2
Diluted	213			228

Earnings (loss) per common share attributable to McKesson: ⁽¹⁾
Diluted
Continuing operations	$	1.44		$	2.88
Discontinued operations	0.01			(0.50		)
Total	$	1.45		$	2.38
Basic
Continuing operations	$	1.46		$	2.91
Discontinued operations	—			(0.50		)
Total	$	1.46		$	2.41


(1)	Certain computations may reflect rounding adjustments.

Potentially dilutive securities include outstanding stock options, restricted stock units, and performance-based and other restricted stock units. Approximately 2 million potentially dilutive securities were excluded from the computations of diluted net earnings per common share for each of the quarters ended June 30, 2017 and 2016, as they were anti-dilutive.
