5.    Earnings Per Share

Net income per common share attributable to Bruker Corporation shareholders is calculated by dividing net income attributable to Bruker Corporation, adjusted to reflect changes in the redemption value of the redeemable noncontrolling interest, by the weighted-average number of 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.   There was no redemption value adjustment of the redeemable noncontrolling interest for the three months ended March 31, 2020 or 2019.

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

	2020		2019
Net income attributable to Bruker Corporation, as reported	$	10.5	$	30.8
Weighted average shares outstanding:
Weighted average shares outstanding-basic		154.2		156.7
Effect of dilutive securities:
Stock options and restricted stock awards and units		1.2		1.2
		155.4		157.9
Net income per common share attributable to Bruker Corporation shareholders:
Basic	$	0.07	$	0.20
Diluted	$	0.07	$	0.20

Stock options to purchase approximately 0.1 million shares were excluded from the computation of diluted earnings per share in the three months ended March 31, 2019 as their effect would have been anti-dilutive.
