12. The current price of a stock is $60. The one-year call option on the stock at a strike of
$60 is trading at $10. If the one-year rate of interest is 10%, is the call price free from
arbitrage, assuming that the stock pays no dividends? What if the stock pays a dividend
of $5 one day before the maturity of the option?

compounded) is flat at 10%. What is the six-month forward price of the stock?
Denote this as F. The six-month call price at strike F is equal to $8. The six-month
