EARNINGS PER SHARE [Abstract]  
Earnings per share
The computation of basic earnings per share (EPS) is based on the number of weighted average common shares outstanding during the period.  The computation of diluted EPS is based on the weighted average number of shares outstanding plus the incremental shares that would be outstanding assuming exercise of dilutive stock options and issuance of restricted stock.  The number of incremental shares is calculated by applying the treasury stock method.  The following table sets forth the computation of basic and diluted earnings per share in thousands:
