EARNINGS PER SHARE

6 Months Ended

Jun. 30, 2023

Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the periods. Diluted earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average common shares and common share equivalents outstanding during the periods. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method, which includes consideration of equity awards.

The following table sets forth the computation of basic and diluted earnings per share for the periods presented:

(1) Basic and diluted earnings per share for the three and six months ended June 30, 2022 were previously calculated and reported based on amounts as presented in thousands. As such, certain prior year amounts may not foot or recalculate based on the amounts as presented in millions in the current year presentation.

The computation of diluted earnings per share attributable to common stockholders excludes stock-based awards that would have had an antidilutive effect on earnings per share. For the three and six months ended June 30, 2023, there were approximately 0.4 million antidilutive shares.
