EARNINGS PER SHARE

6 Months Ended

Jun. 27, 2020

Basic income per share is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted income per share includes the additional effect of all potentially dilutive securities, which includes dilutive stock-based awards granted under stock-based compensation plans.

The following table sets forth the calculation of earnings per share and weighted-average common shares outstanding at the dates indicated (in thousands, except per share data):


	Three Months Ended						Six Months Ended
	June 27, 2020		June 29, 2019		June 27, 2020		June 29, 2019
Net income	$	33,482	$	22,223	$	41,962	$	24,390

Weighted-average common shares outstanding—basic	86,937		84,577		86,883		84,387
Effect of dilutive securities	540		1,650		586		1,655
Weighted-average common shares outstanding—diluted	87,477		86,227		87,469		86,042

Earnings per share
Basic	$	0.39	$	0.26	$	0.48	$	0.29
Diluted	$	0.38	$	0.26	$	0.48	$	0.28

Effects of potentially dilutive securities are presented only in periods in which they are dilutive. For the three months ended June 27, 2020 and June 29, 2019, outstanding stock-based awards representing 0.5 million and 0.5 million shares, respectively, of common stock were excluded from the calculation of diluted earnings per share, because their effect would be anti-dilutive. For the six months ended June 27, 2020 and June 29, 2019, outstanding stock-based awards representing 0.2 million and 1.1 million shares, respectively, of common stock were excluded from the calculation of diluted earnings, because their effect would be anti-dilutive. In addition, 1.3 million shares of performance-based RSUs were excluded from the calculations of diluted earnings per share for the three and six months ended June 29, 2019, because these units were not considered to be contingent outstanding shares.
