23. Ms. Higden has been offered yet another incentive scheme (see Section 20-2 ). She will receive a bonus of $500,000 if the stock price at the end of the year is $120 or more;

otherwise she will receive nothing. (Don’t ask why anyone should want to offer such an arrangement. Maybe there’s some tax angle.)

a. Draw a position diagram illustrating the payoffs from such a scheme.

b. What combination of options would provide these payoffs? ( Hint: You need to buy a large number of options with one exercise price and sell a similar number with a different exercise price.)
