XYZ Corp. will pay a $2 per share dividend in two months. Its stock price currently is $90 per share. A call option on XYZ has an exercise price of $85 and 3-month time to expiration. The risk-free interest rate is 0.6% per month, and the stocks volatility (standard deviation) = 24% per month. Find the Black-Scholes value of the American call option. (Hint: Try defining one period as a month, rather than as a year, and think about the net-of-dividend value of each share.)
