The Company calculates earnings per common share using the two-class method. The two-class method allocates net income to each class of common stock and participating security according to common dividends declared and participation rights in undistributed earnings. 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 per common share follows.

Potential common shares consist of nonvested performance-based awards, nonvested restricted stock units, and 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. The weighted average of potentially dilutive common shares that were anti-dilutive totaled 1,749 and 3,152 for the three and six months ended June 30, 2026, respectively, and 142,030 and 3,008 for the three and six months ended June 30, 2025, respectively, and were excluded from the calculation of diluted earnings per share for the respective periods.
