The premium on the put is theinsurance premium.b.The guaranteed tuition arrangement is a call option granted to you by the school. If you enroll now,you can "purchase" the education at a fixed price up through the next four years. The premium on theoption is the fact that you have to enroll in this particular school for your freshman year.
