Earnings Per Share [Abstract]

Earnings (Loss) Per Common Share

10. Earnings (Loss) Per Common Share

The Company calculates earnings (loss) per share using the two-class method. The two-class method allocates net income or loss to each class of common stock and participating security according to common dividends declared and participation rights in undistributed earnings. For reporting periods in which a net loss is recorded, net loss is not allocated to participating securities because the holders of such securities bear no contractual obligation to fund or otherwise share in the losses. Participating securities consist of nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents. 

A summary of the information used in the computation of earnings (loss) per common share follows.

Potential common shares consist of stock options, nonvested performance-based awards, and nonvested restricted share awards deferred under the Company’s nonqualified deferred compensation plan. These potential common shares do not enter into the calculation of diluted earnings per share if the impact would be antidilutive, i.e., increase earnings per share or reduce a loss per share. Antidilutive potential common shares with weighted averages totaling 752 and 67 for the three and six months ended June 30, 2021, respectively, were excluded from the calculation of earnings per share. For reporting periods in which a net loss is reported, no effect is given to potentially dilutive common shares in the computation of loss per common share as any impact from such shares would be antidilutive.
