 awards on the date of grant using an option pricing model. We use the Black -Scholespricing model to estimate the fair value of options granted that are then expensed on a straight -linebasis over the vesting period. We account for forfeitures as they occur. Option valuation models, including the Black -Scholesoption -pricingmodel, require the input of highly subjective assumptions, and changes in the assumptions used can materially affect the grant -datefair value of an award. These assumptions include the risk -freerate of interest, expected dividend yield, expected volatility, and the expected life of the award. • Expected Term. The expected term is calculated using the simplified method, which is available where there is insufficient historical data about exercise patterns and post -vestingemployment termination behavior. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting -tranchefor awards with graded vesting. The mid -pointbetween the vesting date and the maximum contractual expiration date is used as the expected term under this method. For awards with multiple vesting -tranches, the times from grant until the mid -pointsfor each of the tranches may be averaged to provide an overall expected term. 273 • Expected Volatility. The expected stock price volatility assumption was determined by examining the historical volatilities for industry peers, as we did not have any trading history for our common stock. We will continue to analyze the historical stock price volatility and expected term assumptions as historical data for our common stock becomes available. • Risk -Free Interest Rate. The risk -freeinterest rate is based on the implied yield currently available on U.S. Treasury zero -couponissues with a remaining term equivalent to the expected term of a stock award. • Dividend Yield. We have not paid and does not anticipate paying any dividends in the near future. Accordingly, we have estimated the dividend yield to be zero.
