Problem ESQBSF1.

Similar to Question 20 from the Casualty Actuarial Society's Spring 2007 Exam 3:

You are aware of the following information for the dividend-paying stock of Astonishing Co. and a European call option on that stock. The current stock price is $600, and the call option strike price is $654. The stock's volatility is 0.4, and the expected annual return on the stock is 15%. The annual continuously-compounded risk-free interest rate is 0.12, and the stock's annual continuously-compounded dividend yield is 0.04. The call option expires in 2 years. Find the call price using the Black-Scholes formula.

IMPORTANT: The solution as given here to Problem ESQBSF5 is incorrect. The work for d_1 uses ln(K/S) instead of ln(S/K). I have issued the correct answer to this problem here: http://www.associatedcontent.com/article/703455/errata_for_section_38_of_the_actuarys.html
