11. Earnings per Share

Basic earnings per share is calculated by dividing net earnings attributable to RRD common stockholders by the weighted average number of common shares outstanding for the period. In computing diluted earnings per share, basic earnings per share is adjusted for the assumed issuance of all potentially dilutive share-based awards, including stock options, restricted stock units and performance share units. Performance share units are considered anti-dilutive and excluded if the performance targets upon which the issuance of the shares is contingent have not been achieved and the respective performance period has not been completed as of the end of the current period. Additionally, stock options are considered anti-dilutive when the exercise price exceeds the average of the Company’s stock price during the applicable period. In periods when the Company is in a net loss from continuing operations, share-based awards are excluded from the calculation of earnings per share as their inclusion would have an anti-dilutive effect.

During the six months ended June 30, 2017 and 2016, no shares of common stock were purchased by the Company; however, shares were withheld for tax liabilities upon the vesting of equity awards.

The reconciliation of the numerator and denominator of the basic and diluted earnings per share calculation and the anti-dilutive share-based awards for three and six months ended June 30, 2017 and 2016 were as follows:
