Day and time of your section
Instructions:
You have 80 minutes to complete this test, unless you arrive late. Late arrival will lower the time
available to you, and you must finish at the same time as all other students.
Cheating will not be tolerated during any test. Any suspected cheating will be reported to the relevant
authorities on this issue.
You are allowed to use a nonprogrammable four-function or scientific calculator that is NOT a
communication device. You are NOT allowed to have a calculator that stores formulas, buttons that
automatically calculate IRR, NPV, or any other concept covered in this class. You are NOT allowed to
have a calculator that has the ability to produce graphs. If you use a calculator that does not meet these
requirements, you will be assumed to be cheating.
Unless otherwise specified, you can assume the following:
 Negative internal rates of return are not possible.
 Equivalent annual cost problems are in real dollars.
You are allowed to turn in your test early if there are at least 10 minutes remaining. As a courtesy to your
classmates, you will not be allowed to leave during the final 10 minutes of the test.
Your test should have 10 multiple-choice questions (30 points) and 3 problems (40 points), some with
multiple parts. The maximum possible point total is 71 points. If your test is incomplete, it is your
responsibility to notify a proctor to get a new test.

MULTIPLE CHOICE: Answer the following questions on your scantron. Each correct answer is worth 3
points. All incorrect or blank answers are worth 0 points. If there is an answer that does not exactly
match the correct answer, choose the closest answer.
1. If the annual inflation rate is 5%, what is the exact nominal interest rate if the real interest rate is r?

C. 1.5
D. 2.5
E. 4.5
3. A stock is currently valued at $60, which is the correct current value. Today, news is revealed in which
the new correct value of the stock should be 10% higher. However, the price of the stock increases to $70
today, and the value slowly decreases over the next few days until the new correct value is reached. This
is an example of…
A. Efficient market response to new information
B. Overreaction and reversion

D. A random walk similar to the Halloween night example shown in class
E. None of the above
4. A stock pays $9 every six months, starting nine months from today. If the stated annual interest rate is
12%, compounded every three months, what is the present value of the stock’s payments?
A. $143
B. $146
C. $148
D. $150
E. $152
5. Lucky Seventy Jeans needs to buy a new production machine due to increased sales. The machine costs
$60,000 (which must be paid today) and lasts for 10 years. Two maintenance expenses must be paid. The
first will be in 5 years, at a cost of $6,000. The second will be paid in 8 years, at a cost of $15,000. What
is the equivalent annual cost of this machine if the effective annual interest rate is 9%?
A. $8,000
B. $9,000
C. $10,000
D. $11,000
E. $12,000
6. Arianne currently is set to receive 24 payments of $10,000, starting one year from today. Given her
discount rate, the current annuity factor of this annuity is 10.5288. If she were set to receive 25 payments,
the annuity factor would increase to 10.6748. What is the present value of a $10,000 payment to Arianne
paid 25 years from today?
A. $21
B. $1,500
C. $2,000
D. $4,000
E. $6,000
7. A bond has a face value of $500. This bond has an unusual payout policy. The bond pays a 30%
coupon each of the next 8 years, starting one year from today. Nine years from today, no coupon is paid
but twice the face value is paid to the bondholder. How much is the bond currently worth if the effective
annual discount rate is 5%?
A. $2,500
B. $2,000
C. $1,800
D. $1,600
E. $1,500
8. Joe Blockersfield has just purchased a house. The purchase price is $500,000, and Joe is taking out a
loan for 80% of the house’s price. He is paying the loan back with 30 yearly payments, and the equal
principal reduction each year. How much will the first payment be if the effective annual interest rate is
7%?
A. $32,000
B. $34,000
C. $37,000
D. $39,000
E. $41,000
9. Which statement is always true?
A. Invest in any project that has a NPV > 0
B. Invest in any project with a PI > 1
C. Invest in any project with an effective annual discount rate less than the IRR
D. Invest in any project which is most favorable using the undiscounted payback period method
E. When faced with only two mutually exclusive projects to invest in, invest in the larger project if
the incremental IRR is positive and enough money is available to invest in the larger project
10. A bond has a par value of $5,000. It will pay a 5% coupon each of the next 14 years, starting one year
from today. The bond will mature 14 years from today and pay back the par value. If the bond is currently
selling for $5,000, what is the effective annual discount rate of the bond?
A. 4%
B. 5%
C. 6%
D. 7%
E. 8%
For the following problems, you will need to write out the solution. You must show all work to
receive credit. Each problem (or part of problem) shows the maximum point value. Provide at least
four significant digits to each answer or you may not receive full credit for a correct solution. Show
all work in order to receive credit. You will receive partial credit for incorrect solutions in some
instances. Clearly circle your answer(s) or else you may not receive full credit for a complete and
correct solution.
1. Negreanu’s Noodles stock currently sells for $80 per share. The effective annual discount rate for all
parts of the problem below can be assumed to be 10%.
(a) (6 points) For parts (a) and (b), also assume that the stock will change in value 6 months from today,
18 months from today, and 30 months from today. Each time the value changes, it goes up by $4 with
50% probability, and goes down by $2 with 50% probability. What is the present value of a European call
option with an exercise price of $81 per share and an expiration date 36 months from today?
(b) (6 points) What is the present value of a European put option with an exercise price of $83 and an
expiration date 24 months from today?
(c) (8 points) Suppose that Daniel buys one share of a stock at a price at $80 today, and one European put
option with an exercise price of $120. The option expires twelve months from today.
Draw a well-labeled graph that shows the present value of a combination of the share of stock
and the put option as a function of the value of a single share of stock at the put option’s expiration date.
The vertical intercept should have the value of the combination of the share of stock and the put option.
The horizontal intercept should have the value of a single share of stock at the option’s expiration date.
Make sure to label your intercepts and other relevant numbers on each axis, where relevant. (Hint: You
may want to look at the front page of the test to see a well-labeled graph.)
Please note that you need to justify the labels for the graph you provide. Please provide an
explanation wherever necessary.
2. (8 points) Destination Duffle Bags stock currently has an expected rate of return of 8%. Bonds that are
issued by the same company have a 4% rate of return. Currently, the total value of stocks and bonds is
$100,000, with 60% of the company’s value currently in stocks. If the company issues an additional
$10,000 in bonds and uses this money to pay off stockholders, what is the new expected rate of return to
stockholders after the stockholders are paid? Use MM Proposition II to answer this question, and you can
assume that the rate of return on bonds does not change. You can also assume that the entire value of the
company is through stocks and bonds.
3. (12 points) There are 3 known states of the world, high, medium, and low, each with one third
probability. Conglomerates Anonymous has a rate of return of 2% during the low state, 10% during the
medium state, and 12% during the high state. Special Spade Cards has a rate of return of 5% in the low
state, 6% in the medium state, and 7% in the high state. What is the standard deviation of a portfolio
consisting of 25% of Conglomerates Anonymous and 75% Special Spade Cards. (Note: This requires
many steps. So please make sure it is clear to the grader each step of your work.)
