Stock option fair values are calculated at each measurement date using a Black-Scholes valuation model, consistent with the approach used to value the awards at the grant date. Stock option fair values as of each measurement date were determined using updated assumptions (the closing stock price of our common stock as of the measurement date, risk-free interest rate, expected life, expected volatility of the price of our common stock, and expected dividend yield) and fair value increases are primarily driven by an increase in the price of the Company’s common stock.
