In addition to the five factors discussed in the chapter, dividends also affect the price of an option. The Black-Scholes option pricing model with dividends is: C=S × e−dt × N(d1) − E × e−Rt × N(d2) d1= [ln(S /E ) +(R−d+σ2 / 2) × t ] (σ − t√) d2=d1−σ × t√ All of the variables are the same as the Black-Scholes model without dividends except for the variable d, which is the continuously compounded dividend yield on the stock. A stock is currently priced at $89 per share, the standard deviation of its return is 54 percent per year, and the risk-free rate is 6 percent per year, compounded continuously. What is the price of a call option with a strike price of $85 and a maturity of six months if the stock has a dividend yield of 2 percent per year? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
Price of a call option = $15.92

The time to maturity is 6 months and the same is represented in years as 1/2 (6/12).
