Assumptions Used in Calculating Fair Value of Options

The fair value of options granted was estimated on the date of grant using the Black-Scholes pricing model with the assumptions noted in the following table (all in weighted averages for options granted during the year):

 

     Year Ended September 30,  
     2016     2015     2014  

Risk-free interest rate(1)

     1.40     1.26     1.30

Expected life of stock options(2)

     4.50        4.50        4.50   

Expected volatility(3)

     18.5     15.6     17.3

Expected dividend yield(4)

     1.40     1.37     1.45

Fair value per option

   $ 7.97      $ 5.97      $ 5.56   

 

(1) Risk-free interest rate is based upon U.S. Treasury yield curve appropriate for the term of the Company’s employee stock options.
(2) Expected life of stock options is based upon historical experience.
(3) Expected volatility is based on blended volatility. Please see Note 2 to the consolidated financial statements.
