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 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.
