Assumptions Used in Option Valuation Model
In 2016, 2015 and 2014, we used the Monte Carlo simulation valuation technique to estimate the fair value of TSR performance share grants, which used the assumptions in the below table.

(1) The expected life represents the remaining performance period of the awards.
(2) The expected volatility for each grant is determined based on the historical volatility of 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 based on the continuous compounded yield on U.S. Treasury Constant Maturity Rates with varying remaining terms; the yield is determined over a time period commensurate with the performance period from the grant date.
(4) The stock price is the closing price of our common stock on the valuation date.
