SOLUTIONS TO PROBLEMS P4.1

The investor would earn $8.25 on a stock that paid $3.75 in current income and sold for $67.50. Part of the total dollar return includes a $4.50 capital gain which is the difference between the proceeds of the sale and the original purchase price ($67.50 – $63.00) of the stock.

$2.70

$10

c. Total return: 1) In dollars: $2.70 + $10.00 = $12.70 2) As a percentage of the initial investment: $12.70 = .25 or 25%. 50.00 P4.5

a. Total return = Current income + Capital gains (or losses) where: Capital gains (or losses) = Ending price – Beginning price (3) (4) (5) (1) (2) (1) – (2) (3) + (4) Ending Beginning Capital Current Total Price – Price = Gain + Income = Return Year 2001 $32.50 $30.00 $2.50 $1.00 $3.50 2002 35.00 32.50 2.50 1.20 3.70 2003 33.00 35.00 – 2.00 1.30 – .70 2004 40.00 33.00 7.00 1.60 8.60 2005 45.00 40.00 5.00 1.75 6.75 b. Of course, there is no correct answer here, but one might forecast using the arithmetic average or the average one-year holding period return. (i) The arithmetic average: $3.50 + $3.70 – $.70 + $8.60 + $6.75 = $4.37 5

(ii) The average holding period return (HPR): HPR = Ending price – Beginning price + Current income = Total Return Beginning price Beginning Price (1) Total Year Return* 2001 $3.50 2002 3.70 2003 - .70 2004 8.60 2005 6.75 *From part (a) above.

(2) Beginning Price $30.00 32.50 35.00 33.00 40.00

(3) (1)÷(2) HPR 11.7% 11.4 - 2.0 26.1 16.9

Average HPR = 11.7 + 11.4 – 2.0 + 26.1 + 16.9 5 b. (i) Forecasts for: 2006 2007

(ii) Based on Arithmetic Average $4.37 $4.37

= 12.8%

Based on Average HPR ($45.00)* × .128 = $5.76 ($49.00)** × .128 = $6.27

* End of 2005 price gain in original data. ** For lack of information, we are assuming the 2006 return is $4.00 from capital gains and $1.76 from current income. c. Students should be made aware of the fact that many other forecasts are possible. Other factors may be relevant here: Will the pattern of two good years followed by a bad one continue? Do future prospects seem bright? (We will discuss forecasting returns on specific investment vehicles in later chapters.)

P4.7

The simple interest calculations for parts a. and b. can be presented in tabular form: b. a. Beginning Annual Ending Balance* Interest Balance** Date 1/1/05 $5,000 $5,000 ×.06 = $300 $5,000 1/1/06 1,000 1,000 ×.06 =60 1,000 1/1/07 3,000 3,000 ×.06 =180 3,000 1/1/08 6,000 6,000 ×.06 = 360 6,000 * Assuming all transactions occur at the beginning of the period. ** Since all interest earned is withdrawn, the ending account balance equals the beginning account balance. c. The true rate of interest is 6 percent, the same as the stated rate of interest since the simple interest method is being used.

Future Value of an Investment:

FVn = Investment Amount x (FVIFk,n)

(FVIFA from Appendix A, Table A.2)

P4.13 The least you would accept for each investment is its future value at the end of six years: a. Future Value of an Investment: FVn = Investment Amount × (FVIFk,n) FV9%,6 yrs. = $5,000 × 1.677 = $8,385 Calc. Sol’n = $8,385.50 b. Future Value of an Annuity Investment: FVAk,n = Annual Deposit × FVIFAk,n FVA9%,6 yrs. = $2,000 × 7.523 = $15,046 Calc. Sol’n. = $15,046.67 c.

FV of $3,000 at 9% for 6 years + FVA of $1,000 deposit at 9% at end of each of the next five years: 1. FV9%,6 yrs. = $3,000 × 1.677 (From App. A, Table A.1) = $5,031 Calc. Sol’n = $5,031.30 = $1,000 × 7.523 (From App. A, Table A.2) 2. FVA9%,6 yrs. = $7,523 Calc. Sol’n. = $7,523.33

P4.15 This problem uses present value to solve an investment problem. The amount at which the bond will sell today is the value today of its value at maturity (in eight years), given an interest rate of 6%:. PV = FV × (PVIFk,n) $1,000 ×.627 PV6%, 8 yrs. = = $627 (Calculator Solution = $627.41) P.4.17 This is a present value question. Calculate the present value of $10,000 using a PVIF 3%, 10 periods value. $10,000 x 0.744 = $7,440.

b. Income Stream A, with a present value of $7,636, is higher than Income Stream B’s present value of $6.644 because the larger cash inflows occur in A in the early years when their present value is greater. The smaller cash flows are received further in the future. P4.21 Find the present value of the annuity and compare it to the lump sum payment. PVIVA 8%, 20 periods x $1,000,000 = 9.818 = $9,818,000. Since this is less than $15 million, you should take the $15 million today. P4.23 The analysis of Terri’s investment opportunities uses the formula: FVn = PV × (FVIFk,n) Investment A

An alternative approach accurately answering the same questions would be the calculation of the present value of cash inflows and comparing the results to the investment’s cost. Investment A $30,000 x .621 = $18,630 (using PVIF10%,5 years) Cost of Investment = $18,000 Return exceeds cost - Invest Investment B $3,000 x .149 = $447 (using PVIF10%,20 years) Cost of Investment = $600 Cost exceeds return - forgo Investment C $10,000 x .386 = $3,860 (using PVIF10%,10 years) Cost of Investment = $3,500 Return exceeds cost - Invest Investment D $15,000 x ..022 = $330 (using PVIF10%,40 years) Cost of Investment = $18,000 Cost exceeds return - forgo P4.25 $15,000 = PVIFA1%, 50 payments $15,000 = 39.196 $15,000 / 39.196 = $382.69 P4.27 a. Using the notation given in the chapter, the risk-free rate of interest for both Investments is:

R = r* + IP = 3% + 5% = 8% b. The required returns for each investment are calculated as follows: r1 = r* + IP + RPi or RF + RPi rA = 3% + 5% + 3% 8% + 3% = 11% rB = 3% + 5% + 5% 8% + 5% = 13%

P4.29 Holding period return (HPR) = Current income + Ending price – Beginning price Beginning price HPRX = $1.00 + $1.20 + $0 + $2.30 + $29.00 – $30.00 = $ 3.50 $30.00 $30.00 = 11.67% HPRY = $0 + $0 + $0 + $2.00 + $56.00 – $50.00 50.00 = 16.0%

= $ 8.00 $50.00

If the investments are held beyond a year, the capital gain (loss) component would not be realized and would likely change. Assuming they are of equal risk, Investment Y would be preferred since it offers the higher return (16.0% for Y versus 11.67% for X). P4.31 HPR = ($50 + ($1,000 - $950)) / $950 = $100/$950 = 10.5% P4.33 Using PFIV of 4%: $

(5) Approximate Yield* 4% (.822) 10% (.513) 8% (.215) 5% (.747) 5% (.231)

P4.37 The yield for these investments is the discount rate that results in the stream of income equaling the initial investment. Investment A: Using the present value of an annuity formula: PVA = Annual deposit × PVIFAk%,5 yrs. $8,500 = $2,500 × PVIFAk%,5 yrs. $8,500 = PVIFAk%,5 yrs. $2,500 3.4 = PVIFAk%,5 yrs. Looking at Table A.4, Appendix A, the closest factor for five years occurs at 14% (3.433); therefore, this investment yields about 14%. Investment B: It is necessary to try several different discount rates to determine the yield for Investment B. One way to estimate a starting point is to use the average annual income in the formula used in Part A. and adjusting it based on whether the larger cash flows are received in the earlier or later years. The Internal Rate of Return (IRR) function on a business calculator makes the task easier. PVA = Annual deposit × PVIFAk%,5 yrs. $9,500 = $3,000 × PVIFAk%,5 yrs. $9,500 = PVIFAk%,5 yrs. $3,000 3.167 = PVIFAk%,5 yrs. The closest interest rate to 3.167 in Table A.4, Appendix A, is 17%. Because the larger cash flows are received in the later years, 16% is a good starting point.

Since the yield of 11% is greater than the minimum required return of 9.0%, the investment is recommended. This project would result in positive Net Present Value to the investor P4.41

2004 – 1997 = 7 years $1 x FVIF ?%, 7 years = $2.21 FVIF = $2.21/$1 = 2.21 FVIF 12%, 7 years = 2.211, so the yield is about 12%

P4.43 a. Investment A, with returns that vary widely – from 1% to 26% – appears to be more risky than Investment B, whose returns vary from 8% to 16%. b.

S A = √ 40 = √ 10 = 3.16% 5–1 CV = 3.16% = 0.26 12.00% c. Investment A, with a standard deviation of 10.42, is considerably more risky than Investment B, whose standard deviation is 3.16. This confirms the conclusions reached in Part A. d. Because the real benefit of calculating the coefficient or variation is in comparing investments that have different average returns, the standard deviation is not improved upon.
