rate of 7.0%. What is the expected percentage change in value if the required rate drops to
6.5% immediately after the mortgage is issued?

technique is the same, there are 360 months to handle. Doing this, the duration
can be calculated as 10.15 years.

2.   You would enter into a contract that specifies that you will sell the \$25 million of 8s of 2015
at a price of 110 one year from now.

7. The put option is out of the money because you would not want to take the option to sell the
futures at 95 when the price at expiration is 120. Since the premium is \$4,000 and you did
not exercise the contract, your loss on the contract is \$4,000.

8. You have a profit of 1 point (\$1000) when you exercise the contract, but you have paid a
premium of \$1500 for the call option, so your net profit is \$500, a loss of \$500.

12. You would hedge the risk by buying 80 euro futures contracts that mature 3 months from
now.
