The fair value of stock options is determined using the Black-Scholes option-pricing model using various inputs, including the Company’s estimates of the fair value of common stock on the date of grant, expected term, expected volatility, risk-free interest rate, and expectations regarding future dividends. Stock-based compensation also reflects the Company’s estimate regarding the portion of awards that may be forfeited.
