Earnings Per Share

Basic earnings per share is computed by dividing net income attributable to common shares by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution of securities that could participate in earnings, but not securities that are anti-dilutive. The computations of basic and diluted earnings per share for the quarters and six months ended March 31, 2016 and March 27, 2015 are as follows:



	For the Quarters Ended				For the Six Months Ended
(in millions, except per share amounts)	March 31, 2016		March 27, 2015		March 31, 2016		March 27, 2015

Denominator:
Basic weighted-average shares outstanding	165		171		165		173
Effect of dilutive securities:

Diluted weighted-average shares outstanding	166		172		166		173

Diluted earnings per share	$	0.37	$	0.40	$	0.76	$	0.81

The computation of diluted earnings per share excludes potentially dilutive securities whose effect would have been anti-dilutive in the amount of approximately 2.9 million shares and 2.2 million shares for the quarters ended March 31, 2016 and March 27, 2015, respectively, and approximately 2.8 million shares and 2.2 million shares for the six months ended March 31, 2016 and March 27, 2015, respectively.
