STOCK COMPENSATION PLANS [Abstract]  
Weighted-average assumptions used for grants option
The fair value of each option grant is estimated using the Black-Scholes-Merton option pricing model with the following weighted-average assumptions used for grants issued in 2012 and 2011.  All options were granted at market value with a 10-year option term with a vesting period of one year from the date of grant.

   
2012
  
2011
 
Expected Dividend Yield
  4.18 %  3.99 %
Expected Stock Price Volatility
  25.13 %  24.97 %
Weighted Average Risk-Free Interest Rate
  1.87 %  3.12 %
Weighted Average Expected Life of Options (in years)
  9.47   8.36 

The expected dividend yield was based on a 12-month rolling average of the Company’s dividend yield.  The expected volatility is the standard deviation of the change in the natural logarithm of the stock price (expressed as an annual rate) for the expected term shown above.  The expected term was based on historic exercise patterns for similar grants.  The risk-free interest rate is the 10-year Treasury Constant Maturity rate as of the date of the grants.
