The expected term for options was based on the results of a Monte Carlo simulation model, using the model’s estimated fair value as an input to the Black-Scholes-Merton model, and then solving for the expected term. The risk-free interest rate for periods within the contractual life of the option was based on the U.S. Treasury yield curve in effect at the time of the grant. The expected volatility was derived using a term structure based on historical volatility and the volatility implied by exchange-traded options on our common stock. The dividend yield was calculated based on our annual dividend as of the option grant date.
