Earnings Per Share [Abstract]  
EARNINGS PER SHARE EARNINGS PER SHARE: Basic and diluted earnings per common share (“EPS”) are computed using the two-class method, which is an earnings allocation formula that determines EPS for each class of common stock and participating security. The Company’s restricted stock awards are considered participating securities because they are legally issued at the grant date and holders have a non-forfeitable right to receive dividends.
