Earnings Per Share [Abstract]

Earnings per Share

Note 9. Earnings per Share

Basic earnings per share is calculated by dividing net earnings 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 ("RSUs"), performance share units ("PSUs") and restricted stock.

The reconciliation of the numerator and denominator of the basic and diluted earnings per share calculation and the anti-dilutive share-based awards for the three months ended March 31, 2023 and 2022 were as follows:
