Earnings Per Share [Abstract]  
EARNINGS PER COMMON SHARE EARNINGS PER COMMON SHARE
Basic earnings per common share is computed by dividing net income, excluding net earnings allocated to participating securities, by the weighted average number of shares outstanding during the applicable period, excluding outstanding participating securities. Diluted earnings per common share is computed using the weighted average number of shares determined for the basic computation plus the dilutive effect of potential common shares issuable under certain stock compensation plans. For the three months ended March 31, 2022 and 2021, there were no outstanding stock options to include in the diluted earnings per common share calculations.

Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are included in the computation of earnings per common share pursuant to the two-class method. The Corporation has determined that its outstanding unvested time-based stock awards are participating securities.

The computation of basic and diluted earnings per common share is shown below:
