Share-based Compensation Arrangement by Share-based Payment Award, Options, Maximum Term 10 years
Share-based Compensation Arrangement by Share-based Payment Award, 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.   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.
Share-based Compensation Arrangement by Share-based Payment Award, Description Stock options are valued primarily using the binomial lattice option pricing model and are granted with an exercise price equal to the closing price of our common stock on the grant date. Time-based and performance-based restricted stock awards are valued using the closing price of our common stock on the grant date. For awards that have market conditions, such as attaining a specified stock price or based on total shareholder return, we use a Monte Carlo simulation model to determine the value of the award. Our current plan does not permit awarding stock options below grant-date market value nor does it allow any repricing subsequent to the date of grant.
