5. You plan to analyze the value of a potential investment by calculating the sum of the present values of its expected cash flows. Which of the following would lower the calculated value of the investment?

CHAPTER 5TIME VALUE OF MONEY

Page 2: CHAPTER 5 - Question 7

a. The cash flows are in the form of a deferred annuity, and they total to $100,000. You learn that the annuity lasts for only 5 rather than 10 years, hence that each payment is for $20,000 rather than for $10,000.

b. The discount rate increases.c. The riskiness of the investment’s cash flows decreases.d. The total amount of cash flows remains the same, but more of the cash flows are received in the earlier

years and less are received in the later years.e. The discount rate decreases.Answer: b

6. You plan to analyze the value of a potential investment by calculating the sum of the present values of its expected cash flows. Which of the following would increase the calculated value of the investment?

a. The cash flows are in the form of a deferred annuity, and they total to $100,000. You learn that the annuity lasts for 10 years rather than 5 years, hence that each payment is for $10,000 rather than for $20,000.

b. The discount rate decreases.c. The riskiness of the investment’s cash flows increases.d. The total amount of cash flows remains the same, but more of the cash flows are received in the later

years and less are received in the earlier years.e. The discount rate increases.Answer: b

7. Your bank account pays a 6% nominal rate of interest. The interest is compounded quarterly. Which of the following statements is CORRECT?

a. The periodic rate of interest is 1.5% and the effective rate of interest is 3%.b. The periodic rate of interest is 6% and the effective rate of interest is greater than 6%.c. The periodic rate of interest is 1.5% and the effective rate of interest is greater than 6%.d. The periodic rate of interest is 3% and the effective rate of interest is 6%.e. The periodic rate of interest is 6% and the effective rate of interest is also 6%.Answer: c

8. Your bank account pays an 8% nominal rate of interest. The interest is compounded quarterly. Which of the following statements is CORRECT?

a. The periodic rate of interest is 2% and the effective rate of interest is 4%.b. The periodic rate of interest is 8% and the effective rate of interest is greater than 8%.c. The periodic rate of interest is 4% and the effective rate of interest is less than 8%.d. The periodic rate of interest is 2% and the effective rate of interest is greater than 8%.e. The periodic rate of interest is 8% and the effective rate of interest is also 8%.Answer: d

9. A $50,000 loan is to be amortized over 7 years, with annual end-of-year payments. Which of these statements is CORRECT?

a. The annual payments would be larger if the interest rate were lower.b. If the loan were amortized over 10 years rather than 7 years, and if the interest rate were the same in

either case, the first payment would include more dollars of interest under the 7-year amortization plan.c. The proportion of each payment that represents interest as opposed to repayment of principal would be

lower if the interest rate were lower.d. The last payment would have a higher proportion of interest than the first payment.e. The proportion of interest versus principal repayment would be the same for each of the 7 payments.Answer: c

Page 3: CHAPTER 5 - Question 7

a, d, and e can be ruled out as incorrect by simple reasoning. b is also incorrect because interest in the first year would be Loan amount × interest rate regardless of the life of the loan, so the interest payment would be identical for the first payment. Think about the situation where r = 0%, statement c is the "most logical guess." One could also set up an amortization schedule and change the numbers to confirm that only c is correct.

10. A $150,000 loan is to be amortized over 7 years, with annual end-of-year payments. Which of these statements is CORRECT?

a. The annual payments would be larger if the interest rate were lower.b. If the loan were amortized over 10 years rather than 7 years, and if the interest rate were the same in

either case, the first payment would include more dollars of interest under the 7-year amortization plan.c. The proportion of each payment that represents interest as opposed to repayment of principal would be

higher if the interest rate were lower.d. The proportion of each payment that represents interest versus repayment of principal would be higher

if the interest rate were higher.e. The proportion of interest versus principal repayment would be the same for each of the 7 payments.Answer: d

a, c, and e are obviously incorrect. b is also incorrect because interest in the first year would be Loan amount × interest rate regardless of the life of the loan. That makes d the "most logical guess." One could also set up an amortization schedule and change the numbers to confirm that only d is correct.

11. Which of the following statements regarding a 15-year (180-month) $125,000, fixed-rate mortgage is CORRECT? (Ignore taxes and transactions costs.)

a. The remaining balance after three years will be $125,000 less one third of the interest paid during the first three years.

b. Because it is a fixed-rate mortgage, the monthly loan payments (which include both interest and principal payments) are constant.

c. Interest payments on the mortgage will increase steadily over time, but the total amount of each payment will remain constant.

d. The proportion of the monthly payment that goes towards repayment of principal will be lower 10 years from now than it will be the first year.

e. The outstanding balance declines at a slower rate in the later years of the loan’s life.Answer: b

b is the correct answer. Thinking through the question, the other answers can all be eliminated. One could also set up an amortization schedule to prove that only statement b is correct.

12. Which of the following statements regarding a 15-year (180-month) $125,000, fixed-rate mortgage is CORRECT? (Ignore taxes and transactions costs.)

a. The remaining balance after three years will be $125,000 less one third of the interest paid during the first three years.

b. Because the outstanding balance declines over time, the monthly payments will also decline over time.c. Interest payments on the mortgage will increase steadily over time, but the total amount of each

payment will remain constant.d. The proportion of the monthly payment that goes towards repayment of principal will be lower 10

years from now than it will be the first year.e. The outstanding balance declines at a faster rate in the later years of the loan’s life.Answer: e

e is the correct answer. Thinking through the question, the other answers can all be eliminated. One could also set up an amortization schedule to prove that only statement e is correct.

Page 4: CHAPTER 5 - Question 7

13. Which of the following statements regarding a 30-year monthly payment amortized mortgage with a nominal interest rate of 10% is CORRECT?

a. The monthly payments will decline over time.b. A smaller proportion of the last monthly payment will be interest, and a larger proportion will be

principal, than for the first monthly payment.c. The total dollar amount of principal being paid off each month gets smaller as the loan approaches

maturity.d. The amount representing interest in the first payment would be higher if the nominal interest rate were

7% rather than 10%.e. Exactly 10% of the first monthly payment represents interest.Answer: b

b is correct. a is clearly wrong, as are c and d. It is not obvious whether e is correct or not, but we could set up an example to see:

Loan 100000 Term 30Rate 10% Periods/Year 12Periodic rate 0.008333333 Total periods 360

Payment -$877.57 Interest, Month 1 $833.33Interest as % of total #360 payment: 1% Interest, Month 360 $7.25Principal as % of total #360 payment 99% Principal, Month 360 $870.32

14. Which of the following statements regarding a 30-year monthly payment amortized mortgage with a nominal interest rate of 10% is CORRECT?

principal, than for the last monthly payment.c. The total dollar amount of interest being paid off each month gets larger as the loan approaches

maturity.d. The amount representing interest in the first payment would be higher if the nominal interest rate were

7% rather than 10%.e. Exactly 10% of the first monthly payment represents interest.Answer: b

b is correct. a is clearly wrong, as are c and d. It is not obvious whether e is correct or not, but we could set up an example to see:

Loan 100000 Term 30Rate 10% Periods/Year 12Periodic rate 0.00833333 Total periods 360

Payment -$877.57 Interest Month 1 $833.33Interest as % of total payment: 95%, which is much larger than 10%.

15. A U.S. Treasury bond will pay a lump sum of $1,000 exactly 3 years from today. The nominal interest rate is 6%, semiannual compounding. Which of the following statements is CORRECT?

a. The periodic interest rate is greater than 3%.b. The periodic rate is less than 3%.c. The present value would be greater if the lump sum were discounted back for more periods.d. The present value of the $1,000 would be smaller if interest were compounded monthly rather than

semiannually.
