Stock-Based Compensation


In 2011, the Company recognized $95 in equity compensation cost, compared to $83 in 2010 and $98 in 2009.


The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions:


   
Years ended December 31,
 
   
2011
   
2010
   
2009
 
                   
Expected dividend amount per quarter
  $ 0.2449     $ 0.2471     $ 0.2466  
Expected stock price volatility
    22.8 %     22.0 %     21.6 %
Risk-free interest rate
    1.19 %     2.08 %     1.76 %
Expected life of options
 
3.6 years
   
4.5 years
   
4.7 years
 


The per share weighted average fair value of options granted during 2011, 2010 and 2009 is $3.09, $3.71 and $2.62, respectively.


All UTMD options vest over a four-year service period.  Expected dividend amounts were estimated based on the actual cash dividend rate at the time the options were granted and an estimate of future dividends based on past dividend rate changes as well as management’s expectations of future dividend rates over the expected holding period of the options.  Expected volatility is based on UTMD’s historical volatility over recent periods of time and trends in that volatility, giving weight to more recent periods.  Risk free interest rates were estimated based on actual U.S. Treasury Securities Interest rates as reported by the Federal Reserve Bank for periods of time equivalent to the holding periods estimated for the options on the dates the options were granted.  Expected term of options were estimated based on historical holding periods for similar options previously granted by UTMD to employees and directors.
