PV of Perpetuity Jil is due to receive $50,000 every

2 years, forever, starting one year from today. What is the PV of this perpetuity if her effective annual discount rate is 7%? Rate every 2 years = (1.07)2 – 1 =

14.49% (In $1000’s): 50/.1449 * 1.07 =

369.22 PV = $369,220

Loan Payments Remi is taking out a loan for a $20,000 car. He will

make a 20% down payment and borrow the rest, and will pay off the loan with 40 monthly payments. Each month, he will pay off a constant amount of the principal. How much will the first payment be if Remi’s stated annual interest rate is 12%, compounded monthly?

Loan = 0.8 * $20,000 = $16,000 1st payment:

Principal = 16,000/40 = $400 Interest = 16,000 * 0.01 = $160

1st payment = $400 + $160 = $560

Bonds William’s bond will mature in 10

years. The amount that he will receive in 10 years will be $8,000. Assume William’s effective annual discount rate is 5% over the next 3 years, and 9% thereafter. What is the PV of this bond? $8,000 / (1.05)3(1.09)7 = $3780.39

Discount Rates and IRRs Liam is analyzing a project with

cash flows at multiple times. He knows that if the discount rate is 14%, the NPV of the project is positive. If the discount rate is 18%, the NPV is negative. Which statement MUST be true? NPV must hit zero somewhere

between 14% and 18%, so an IRR must exist between 14% and 18%

Leverage and Returns Joel’s Textboks, Inc. is currently an

unlevered company. The current expected return on equity is 12%. If the cost of debt is 7 an Joel’s Textbooks decides to move 60% of the value of the company to bonds, what will the new return on equity be? 12% = 0.6 * 7% + 0.4 * X 12% = 4.2% + 0.4 * X 7.8% = 0.4 * X X = 19.5%

Value of Options Tlinches stock sells for $75/share

today. The value of the stock in one year will come from a uniform distribution, with lower bound $71 and upper bound $81. What is the PV of a European put option with exercise price $67 and expiration date one year from today? The stock will never be below $67 on

the expiration date, so PV = $0

Decreasing Dividends Silly Spring Stock plans on paying out a dividend of

$1/share today. Each subsequent annual dividend will be 1 cent less than the previous, until the dividend paid is 1¢. After the 1¢ dividend is paid, the company will go out of business. The effective annual discount rate is 10%. What is the PV of this stock?

Upper bound on PV is a dividend that goes on forever and does not decrease

Upper bound: $1 / .1 = $10 All other answer choices are greater than $10, so it is the

closest answer

Calculating Dividends Slimy Mushroom Music (SMM) stock

currently sells for $50/share. The beta value for SMM is 1. The risk-free rate of return is currently 4%, and the risk premium is currently 7%. SMM will pay a yearly dividend of $X every year forever, starting one year from today. What is X?

Discount rate for SMM is .04 + .07 = .11 $50 = X / .11 X = $5.50

Geometric Average Return A stock is worth $500/share today.

One year ago, the value was $450/share. Two years ago, the value was $400/share. Three years ago, the value was $350/share. What has been the geometric average rate of return over the last three years? (500/350)1/3 – 1 = 12.625%

Bonds with Changing Yields A zero-coupon bond is purchased for $1,000

at 11 am today, with a face value of $1,250 to be paid two years from today. Later today, at 1:30 pm, the yield to maturity (compounded on an annual basis) changes to 10%. How much does the value of the bond go up between 11 am and 1:30 pm today?

Value at 11 am = $1,000 Value at 1:30 pm = 1,250/(1.1)2 = $1,033.06 Bond value went up by $33.06

Portfolio Standard Deviation Stocks M and N are uncorrelated

with each other. Stock M has an expected return of 5% and a standard deviation of 6%. Stock N has an expected return of 8% and a standard deviation of 10%. What is the standard deviation of a portfolio that has 30% of stock M and 70% of stock N?

Portfolio Standard Deviation Variance = (.3)2(.06)2 + 0 +

(.7)2(.1)2

= .000324 + 0 + .0049 = .005224

Standard deviation = .072277

(Since M and N are uncorrelated)

Option Value U2B4 stock was valued at $60 three years

ago, and has had a geometric average rate of return of 5% over the past three years. Savannah bought an American call option with an exercise price of $68 a few weeks ago. The option expires today. What is the current value of the option if Savannah’s effective annual discount rate is 6%?

Current value = 60 * (1.05)3 = $69.46 Value of option = 69.46 – 68 = $1.46

Project Discount Rates Janie’s Noodles currently has a company-

wide beta value of 2. A stock whose beta is 1 has an expected return of 5%. The risk-free rate is currently 3%. A new project that Janie’s Noodles is considering has a beta value of 1.5. What is the relevant discount rate for this new project?

Risk premium = 5% - 3% = 2% X = 3% + 1.5 * (2%) = 6%

Non-annual Discount Rates If the effective annual discount

rate is 10%, what is the effective discount rate for 9 months? Rate every 3 months = (1.1)1/4 – 1

= 2.41137% Rate every 9 months = (1.0241137)3 –

1= 7.40995%

Probability of Positive Option Value A stock is currently priced at $65.

The stock’s price will change by $2 per year every year, starting 11 months from today. The stock’s price will go up with 50% probability and down with 50% probability. Each change in the stock’s price is independent of all other price changes.

Probability of Positive Option Value Sonia buys a European option with

an exercise price of $70 and an expiration date in five years. What is the probability that the option will have a positive value on the expiration date? Only times with positive value:

UUUUU, DUUUU, UDUUU, UUDUU, UUUDU, UUUUD

25 = 32 possible outcomes, equal chances

6/32 = 3/16 probability of positive value

Jenny’s Furniture Manufacturing (JFM) is considering moving away from California. In order to try to keep JFM in the state, the government is offering to guarantee any bond repayment for bonds issued by JFM this year. JFM’s normal cost of debt capital is 15%.

Value of Bond Guarantees

If JFM is able to issue $1,000,000 in bonds at a coupon rate of 9%, what is the value of this implicit subsidy? NPV = 1,000,000 – [90,000/1.15 +

90,000/1.152 + 90,000/1.153 + 90,000/1.154 + 90,000/1.155 + 1,090,000/1.156]

NPV = 1,000,000 – [78,260.87 + 68,052.93 + 59,176.46 + 51,457.79 + 44,745.91 + 471,237.08

NPV = $227,068.96

Standard Deviation of Stock Returns Suppose the returns of a stock over a four-

year period are 15%, -6%, 19%, and 22%. Find the standard deviation of this sample. Arithmetic average = (15+(-6)+19+22) / 4 =

12.5% Variance= 1/3 * [(.15-.125)2 + (-.06-.125)2 +

(.19-.125)2 + (.22-.125)2] Variance= 1/3 * [.000625 + .034225 + .004225

+ .009025] = 1/3*[.0481] = .01603 Standard deviation = (.01603)1/2 = .126623 Standard deviation = 12.6623%

Annuity Payments An annuity will pay $5 one year from today,

$(5+Y) two years from today, $(5+2Y) three years from today, and $(5+3Y) four years from today. The PV of this annuity is $15, and the effective annual discount rate is 20%. Find Y.

5/1.2 + (5+Y)/1.22 + (5+2Y)/1.23 + (5+3Y)/1.24 = 15

12.9437 + 3.29861*Y = 15 3.29861*Y = 2.0563 Y = 0.623384

Equivalent Annual Cost The Jack Crock Griller costs $6,000

to purchase today and lasts for 9 years. Annual maintenance costs are required. The first annual cost will be $100 one year from today. Each subsequent maintenance cost will be 6% higher than the previous year’s cost. The final cost will be 8 years from today.

Equivalent Annual Cost What is the equivalent annual cost

if the stated annual discount rate is 12%, compounded every six months? EAIR = (1 + .12/2)2 – 1 = 12.36% PV of costs = 6000 +

100*[1/(.1236-.06) – 1/(.1236-.06) * (1.06/1.1236)8] = $6,585.30

EAC: 6585.30 = X/.1236 * [1 – 1/(1.12369)]

6585.30 = 5.25612 * X X = $1,252.88

Funding Future Withdrawals Wendy has two financial

objectives. She would like to withdraw $500,000 every year for 30 years, starting 5 years from now. She would like to donate $3,000,000 to a charity 30 years from today. Wendy will make a single deposit in 3 years to exactly fund these goals. How much will she have to deposit if the EAIR = 4%?

Funding Future Withdrawals First objective:

FVYear 4 = 500,000/.04 * [1 – 1/(1.0430)] = $8,646,016.65 FVYear 3 = 8,646,016.65/1.04 =

$8,313,477.55 Second objective:

FVYear 3 = 3,000,000/(1.0427) = $1,040,449.71

Total in year 3 = $9,353,927.26
