INCOME PER COMMON SHARE [Abstract]  
INCOME PER COMMON SHARE
7. INCOME PER COMMON SHARE
 
Basic net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding.  Diluted net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding, plus the dilutive effect of stock options and warrants.  The dilutive effect of stock options and warrants is calculated under the treasury stock method using the average market price for the period.  Certain common stock equivalents related to options were not included in the computation of diluted net income per share in the third quarter and first nine months of 2011 because those option exercise prices were greater than the average market price of the common shares.

Basic and diluted earnings per common share for the third quarter and nine months periods were calculated using the weighted average shares as follows:
