4.Earnings Per Share

Net income per common share attributable to Bruker Corporation shareholders is calculated by dividing net income attributable to Bruker Corporation by the weighted-average shares outstanding during the period. The diluted net income per share computation includes the effect of shares which would be issuable upon the exercise of outstanding stock options and the vesting of restricted stock, reduced by the number of shares which are assumed to be purchased by the Company under the treasury stock method.

The following table sets forth the computation of basic and diluted weighted average shares outstanding and net income per common share attributable to Bruker Corporation shareholders (in millions, except per share amounts):

	Three Months Ended March 31,
	2017		2016
Net income attributable to Bruker Corporation, as reported	$	21.6	$	23.6
Weighted average shares outstanding:
Weighted average shares outstanding-basic	159.7		163.3
Effect of dilutive securities:
Stock options and restricted stock	0.8		1.0
	160.5		164.3
Net income per common share attributable to Bruker Corporation shareholders:
Basic	$	0.14	$	0.14
Diluted	$	0.13	$	0.14

Stock options to purchase approximately 0.3 million shares and 0.0 million shares were excluded from the computation of diluted earnings per share in the three months ended March 31, 2017 and 2016, respectively, as their effect would have been anti-dilutive.
