(1) The performance-based unvested RSU’s are shown in this table at target, except for the number of shares vested, which reflect the shares earned. As of July 31, 2016, the maximum number of performance-based unvested RSU’s available to be earned is 334,228.
(2) In addition to the vested options, we expect a portion of the unvested options to vest at some point in the future. Stock options expected to vest are calculated by applying an estimated forfeiture rate to the unvested options.

Fair Value of Option Grant Assumptions

The fair values of option grants were estimated on the grant date using the following assumptions for fiscal years 2015 and 2014:

 

         For the Year ended July 31,    
         2015             2014      

Expected option term in years (1)

      5.31        5.37   

Expected volatility (2)

      29.3 %      38.6 % 

Risk-free interest rate (3)

      1.82 %      1.77 % 

Expected annual dividend yield (4)

      0.56 %      0.52 % 

Weighted average grant date fair value

    $ 19.95      $ 27.55   

 

(1) The expected option term was estimated using historical data.
(2) The expected volatility for each grant is determined based on the review of the average of historical daily price changes of our common stock over the expected option term.
(3) The risk-free interest rate is determined based on the yield of zero-coupon U.S. Treasury securities for a period that is commensurate with the expected term assumption.
(4) The expected annual dividend yield is calculated by dividing the expected annual dividends by the stock price on the date of grant.
  
Fair Value of Awards Grant Assumptions

The fair value of our TSR awards at the date of grant was estimated using the Monte-Carlo simulation model with the following assumptions:

 

     For the Year ended July 31,  
     2016     2015     2014  

Stock price (1)

    $ 84.06      $ 71.33      $ 77.14   

Expected volatility (2)

      26.4 %      29.3 %      27.6 % 

Risk-free interest rate (3)

      1.04 %      1.00 %      0.82 % 

Expected annual dividend yield (4)

      0.00 %      0.00 %      0.00 % 

Weighted average grant date fair value of time-based restricted stock awards

    $ 82.63      $ 73.23      $ 82.46   

Weighted average grant date fair value of performance based restricted stock awards

    $ 98.81      $ 78.62      $ 93.85   

 

(1) The stock price is the closing price of our common stock on the date of grant.
(2) The expected volatility for each grant is determined based on the historical volatility for the peer group companies and our common stock over a period equal to the remaining term of the performance period from the date of grant for all awards.
(3) The risk-free interest rate is determined based on the yield of zero-coupon U.S. Treasury securities for a period that is commensurate with the performance period.
(4) Dividends are considered reinvested when calculating TSR. The dividend yield is therefore considered to be 0%.
