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. In January 2020, the Company acquired the remaining interest in our redeemable noncontrolling interest. There was no redemption value adjustment of the redeemable noncontrolling interest for the three and nine months ended September 30, 2020 or 2019.
