Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding. Diluted earnings per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period, increased to include the number of shares of common stock that would have been outstanding had potential dilutive shares of common stock been issued. The dilutive effect of stock options, RSUs and performance share units are reflected in diluted earnings per share by applying the treasury stock method.

A reconciliation of the amounts included in the computation of basic earnings per share from continuing operations and diluted earnings per share from continuing operations is as follows:



	Three Months Ended				Six Months Ended
	June 30,				June 30,

(In millions, except per share data)	2020		2019		2020		2019
Income from continuing operations	$	40	$	42	$	41	$	95
Weighted-average common shares outstanding		131.9		136.0		133.4		135.9
Effect of dilutive securities:
RSUs⁽¹⁾		0.1		0.2		0.1		0.2
Stock options⁽²⁾		—		0.3		—		0.2
Weighted-average common shares outstanding—assuming dilution		132.0		136.5		133.5		136.3
Basic earnings per share from continuing operations	$	0.30	$	0.31	$	0.31	$	0.70
Diluted earnings per share from continuing operations	$	0.30	$	0.30	$	0.31	$	0.70

(1)RSUs to purchase 0.1 million shares for the three and six months ended June 30, 2020 were not included in the diluted earnings per share calculation because their effect would have been anti-dilutive.

(2)Options to purchase 1.6 million shares for the three months ended June 30, 2020, and 1.4 million and 0.4 million shares for the six months ended June 30, 2020, and 2019, respectively, were not included in the diluted earnings per share calculation because their effect would have been anti-dilutive.
