Fair value assumptions, method used Valuation Method. We estimate the fair value of stock option awards on the date of grant using primarily the binomial lattice model. We believe that the binomial lattice model is a more accurate model for valuing employee stock options since it better reflects the impact of stock price changes on option exercise behavior.   Expected Term. Our expected option term represents the average period that we expect stock options to be outstanding and is determined based on our historical experience, giving consideration to contractual terms, vesting schedules, anticipated stock prices and expected future behavior of option holders.   Expected Volatility. Our expected volatility is based on a blend of the historical volatility of JCPenney stock combined with an estimate of the implied volatility derived from exchange traded options.   Risk-Free Interest Rate. Our risk-free interest rate is based on zero-coupon U.S. Treasury yields in effect at the date of grant with the same period as the expected option life. Expected Dividend Yield. The dividend assumption is based on our current expectations about our dividend policy.
