Title: Investment Analysis (Chapter 17)


1
Investment Analysis(Chapter 17)
2
Objectives
  • Explain the time value of money and its use in
    decision making and investment analysis.
  • Illustrate the process of determining the future
    value or present value of a sum of money or a
    series of payments.
  • Discuss the payback period, simple rate of
    return, net present value, and internal rate of
    return.
  • Introduce how income taxes, inflation, and risk
    affect investment analysis.

3
Investment in Capital Assets
  • Capital assets are long-lasting assets.
  • Investment decisions are made less frequently.
  • Large initial expense.
  • Expenses and returns spread over a number of
    future time periods.
  • Note that time is a critical element!
  • Cannot make such decisions and ignore the time
    element!

4
Time Value of Money
  • Would you rather have a dollar today or at some
    time in the future?
  • A dollar received today can be invested to earn
    interest.
  • Interest represents the opportunity cost of using
    money today.

5
Why is interest charged?
  • Consumption
  • We would prefer to have the dollar now so we
    could spend it and enjoy the new item.
  • Risk
  • Unforeseen circumstance could prevent us from
    collecting the dollar in the future.
  • Inflation
  • The general increase in the cost of goods and
    services may diminish what the dollar can buy in
    the future compared to today.
  • Now time for some new terminology

6
Future Value(FV)
  • The amount of money to be received at some future
    time.
  • OR
  • The amount a present dollar value will become at
    some future date when invested at a given
    interest rate.

7
Present Value(PV)
  • The amount of money available or invested at the
    current time
  • Easy to determine.
  • The current value of some amount(s) to be
    received in the future
  • More difficult, since interest plays a role.
  • Need to discount back to the present!

8
Payment(PMT)
  • The amount of money to be paid or received at the
    end of each of a number of time periods.

9
Interest Rate(i)
  • Also called the discount rate.
  • The interest rate used to find present and future
    values.
  • Often equal to the opportunity cost of capital.
  • What is appropriate interest rate??
  • If borrowing money?
  • If using own money?

10
Time Periods(n)
  • The number of time periods to be used for
    computing present and future values
  • 1 year or several years.
  • 1 month on several months.
  • The annual interest rate i must be adjusted to
    the length of the time periods
  • The standard is annual (one year), so no
    adjustment necessary.
  • A monthly rate must be used if the time periods
    are months (1/12 of the annual rate).
  • A quarterly rate must be used if the time periods
    are quarters (1/4 of the annual rate).

11
Annuity
  • A series of equal periodic payments.
  • Receipts
  • Expenditures
  • Now lets look more carefully at the concepts of
    future and present value.

12
Future Value of a Present Amount
  • The value of a current investment at a specific
    date in the future.
  • What will a given amount of money today be worth
    at some date in the future?
  • This value depends on
  • PV amount.
  • Interest rate.
  • Length of time.

13
Future Value of a Present Amount
  • Assumptions
  • Investment earns interest.
  • Interest is reinvested.
  • The future value includes
  • The original investment and the interest it has
    earned.
  • The interest on the accumulated interest
    (compounding).

14
Future Value of a Present Amount(1,000
invested for 3 years at 8 interest)
  • FV PV (1 i)n
  • Year 1 FV 1000 (1 0.08)1 1000 (1.080)
    1080.00
  • Year 2 FV 1000 (1 0.08)2 1000 (1.1664)
    1166.40
  • Year 3 FV 1000 (1 0.08)3 1000 (1.2597)
    1259.70

15
Future Value of a Present Amount
  • FV PV (1 i)n
  • Appendix Table 2 (text page 420).
  • Calculates (1i)n for a range of i and n.
  • - based on 1, so must multiply by PV.
  • Look under i 8 for 1, 2, and 3 years.
  • What is FV of 100 invested for 10 years
    at 5.0?
  • Answer

16
Rule of 72
  • To find the approximate time it takes for an
    investment to double divide 72 by the interest
    rate.
  • Example
  • An investment at 8 interest will double in
    approximately 9 years 72 8 9
  • Check this approximation with the table value?
  • Table value is 1.999 (look under 8 and 9 years)

17
Future Value of an Annuity
  • What is the future value of a number of payments
    made at the end of each year for a given number
    of years?
  • Each payment will earn interest from the time it
    is invested until the last payment is made.

18
Future Value of an Annuity(1000 at the end of
each year for 3 years at 8)
  • First payment 1,000
    1,000(1 0.08)2 1,166.40
  • Second payment 1,000 1,000(1
    0.08)1 1,080.00
  • Third payment 1,000 1,000(1
    0.08)0 1,000.00
  • Future value 3,246.40
  • FV PMT (1 i)n - 1
  • i
  • Appendix Table 3
  • 1000 (3.2464) 3,246.40

19
FV for a Present Sum and for an Annuity
FV for a single payment FV of
an annuity
20
Present Value
  • The value today of a sum of money to be received
    or paid in the future.
  • A sum to be received in the future is worth less
    than the same amount available today.
  • The future value is discounted back to the
    present.

21
Present Value
  • The sum of money that would have to be invested
    now at the certain interest rate to equal a given
    future value on the same date.
  • Interest rate is called the discount rate.
  • Compounding and discounting are opposite
    procedures.

22
Relationship Between Compounding Discounting
Compounding (FV)
Discounting (PV)
23
Present Valueof a Future Amount
  • The future value is known.
  • The problem is to find the present value of that
    amount.
  • The PV of a FV depends on
  • Interest rate.
  • Length of time
  • High interest rates long time periods will
    reduce the PV.
  • Low interest rates short time periods will
    increase the PV.

24
Present Value of a Single Future Payment
  • PV FV OR FV 1/(1i)n
  • (1 i)n
  • Example A payment of 1,000 to be received in 5
    years using an interest rate of 8 has a PV of
    680.58 (1000/1.4693).
  • An investor should not pay more than 680.58 for
    an investment that will return 1,000 in 5 years
    if the appropriate interest rate is 8.

25
Present Value of a Single Future Payment
  • PV FV OR FV 1/(1i)n
  • (1 i)n
  • Appendix Table 4
  • 5 years at 8 is
  • 0.68058
  • Note gives 1/(1i)n so multiply!
  • 1,000 (0.68058) 680.58

26
Powerball Choices
  • You won the 25 million jackpot
  • 1. Can take the discounted value
  • 14,275,000.00 (current payout).
  • 2. Take the 25-year payout
  • 1,000,000 per year for 25 years.
  • How to approach (personal or economic)?
  • What is implied discount rate for the present
    value (14,275,000) of this 1,000,000 annuity?
  • 14,275,000 1,000,000 14.275 (table value)
  • implied i of between 4.5 and 5.

27
Present Value of an Annuity(1,000 at the end of
the year for 3 years at 8)
  • PV PMT 1 (1 i)-n

  • i
  • Appendix Table 5
  • (1,000 X 2.5771) 2,577.10

29
Some Points about PVs FVs
  • PVs are more useful than FVs when analyzing
    investments
  • Not all investments have the same
  • Useful lives.
  • Pattern of net cash flows.
  • FVs are not directly comparable
  • Different years.
  • Different amounts.
  • FVs are comparable after they have been
    discounted to a common point in time
  • The present!

30
Investment Analysis
  • Determining if the investment is profitable.
  • Comparing the profitability of two or more
    investments.
  • Must know
  • Initial cost.
  • Annual net cash revenues.
  • Terminal or salvage value.
  • Interest or discount rate to be used.

31
Investment Analysis
  • Payback Period
  • Simple Rate of Return
  • Net Present Value
  • Internal Rate of Return

32
Investment Analysis
  • Payback Period (P)
  • The number of years it would take an investment
    to return its original cost through the annual
    net cash revenues it generates
  • Used to rank investments.
  • Establish a minimum payback period.
  • If net cash returns are equal
  • P Cost/Net cash revenue per year.
  • If net cash returns are unequal
  • Sum annual cash revenue year by year until total
    revenue is equal to initial cost and identify the
    years necessary to reach that point.

33
Investment Analysis
  • Payback Period (P)
  • Example 1
  • Cost of investment 10,000.
  • Net cash revenue 2,500 year for 6 years.
  • P 10,000/2,500 4.
  • Example 2
  • Cost 10,000.
  • Net cash revenue year 1 of 500 year 2 of
    1,500
  • year 3 of
    2,500 year 4 of 5,500
  • year 5 of
    6,000 year 6 of 5,000.
  • P 500 1,500 2,500 5,500 4.

34
Investment Analysis
  • Payback Period
  • Advantages
  • Easy to use.
  • Identifies investments with the most immediate
    cash returns.
  • Weaknesses
  • Ignores cash flows after the payback period.
  • Ignores timing of cash flows.
  • Can lead to poor investment decisions (liquidity
    focus).

35
Investment Analysis
  • Simple Rate of Return (RR)
  • Expresses the average annual net revenue as a
    percent return on the investment.
  • Simple rate of return Average annual net
    revenue

  • Initial Cost
  • Multiply times 100 to convert to return.
  • Net revenue is the average annual net cash
    revenue minus the average annual depreciation.

36
Investment Analysis
  • Simple Rate of Return (RR)
  • Example 1
  • Cost of investment 10,000.
  • Net revenue 2,500 year for 6 years
  • Depreciation 1,000/year.
  • RR (1,500/10,000) 0.15 x 100 15.
  • Example 2
  • Cost 10,000 (depreciation 1,000/year).
  • Net cash revenue year 1 of -500 year 2 of
    1,500
  • year 3 of
    2,500 year 4 of 5,500
  • year 5 of
    5,000 year 6 of 1,000.
  • RR (- 1500 500 1,500 4,500 4,000
    0)/6 1,500 1,500/10,000 0.15 x
    100 15.

37
Investment Analysis
  • Simple Rate of Return (RR)
  • Strength
  • Considers an investments earnings over its
    entire life.
  • Weakness
  • Ignores the size and timing of earnings.

38
Investment Analysis
  • Net Present Value (NPV)
  • The sum of the present values for each years net
    cash flow, minus the initial cost of the
    investment
  • NPV P1 P2 . . . Pn -
    C

40
Investment Analysis
  • Net Present Value (NPV)
  • Example 1
  • Cost of investment 10,000.
  • Net cash revenue 2,500 year for 6 years
  • Discount rate 8.
  • Table 4
  • Year Payment PV Factor Present

    1,701.45
  • 6 2,500 0.63017
    1,575.43

  • Total 11,557.72
  • NPV 11,557.72 10,000.00 1,557.72

41
Investment Analysis
  • Net Present Value (NPV)
  • Example 1 (NPV 11,557.72 10,000)
  • Two Issues
  • 1. Since constant net cash revenue each year, is
    there an easier way?
  • Is a 6 year constant annuity of 2,500.
  • PV 2,500 x (Table 5 value of 4.6229)
    11,557.25.
  • 2. What about residual value of investment?
  • Depreciation 1,000/year or 6,000.
  • Residual 4,000 at end of year 6!
  • PV 4,000 (0.63017) 2,520.68
  • Add to NPV of 1,557.72.
  • NPV (including residual value) 4,078.40.

42
Investment Analysis
  • Net Present Value (NPV)
  • Considers the time value of money and the size of
    the stream of cash flows over the entire life of
    the investment.
  • A positive NPV indicates that the rate of return
    on the investment is greater than the discount
    rate.
  • Accept investments with a positive NPV.
  • Reject investments with a negative NPV.

43
Investment Analysis
  • Internal Rate of Return (IRR)
  • The actual rate of return on an investment, with
    proper accounting for the time value of money.
  • The discount rate that makes the NPV just equal
    to zero
  • When the NPV is positive, the IRR is greater than
    the discount rate.
  • When the NPV is negative, the IRR is less than
    the discount rate.

44
Estimation of IRR
Example from textbook
  •  

45
Investment Analysis
  • IRR Drawbacks
  • Difficult to calculate (is IRR function in
    excel).
  • Assumes the annual net returns from the
    investment can be reinvested each period to earn
    a return equal to the IRR.
  • Ignores the size of the investment.

46
Financial Feasibility
  • Final step in investment analysis.
  • Is the investment financially feasible?
  • Will the investment generate sufficient cash
    flows at the right time to meet the required cash
    outflows, including loan payments?

47
Financial Feasibility
  •  

NPV 1,370
NPV 1,272 IRR 15.2
IRR
13.8 Assumes 10,000 borrowed at 8 percent with 5
principal payments of 2,000 interest.
48
Financial Feasibility
  • Taking care of negative cash flows (investment B)
  • Use equity capital for part or all of the initial
    cost of the investment.
  • Lengthen the payment schedule of the loan to make
    the debt payments smaller
  • Smaller payments with a balloon payment at the
    end.
  • Interest-only payments for the first few years.
  • Use excess cash from other parts of the business
    or from savings.

49
Income Taxes
  • Investment analysis didnt consider the effects
    of income taxes on net cash revenues.
  • Investments generate
  • Taxable income.
  • Deductible expenses.
  • Different investments may affect income taxes
    differently
  • Compare them on an after-tax basis

50
Inflation
  • A general increase in price levels over time.
  • Inflation affects
  • Net cash revenues.
  • Terminal value.
  • Discount rate.
  • Two parts of a discount rate
  • Real interest rate
  • - interest rate without inflation
  • 2. Adjustment for inflation.

51
Inflation
  • Two ways to treat inflation in capital budgeting
  • Estimate net cash revenues for each year and the
    terminal value, using current prices, then
    discount these values using a real (nominal rate
    - inflation rate) discount rate.
  • Increase the net cash revenues for each year and
    the terminal value to reflect the expected
    inflation rate, and then use a nominal discount
    rate.
  • For comparing investments, inflation may not
    matter unless they are impacted differently by
    inflation.

52
Risk
  • Unexpected changes can make a potentially
    profitable investment unprofitable
  • Net cash revenues.
  • Terminal value.
  • Future production.
  • Prices.
  • Costs.
  • Add a risk premium to the discount rate
  • Investments with greater risk would have a higher
    risk premium.
  • Margin for error.

53
Sensitivity Analysis
  • Asking What if? questions.
  • What if the net cash revenues were higher or
    lower?
  • What if the timing of net cash revenues was
    different?
  • What if the discount rate was higher or lower?
  • Change one or more values and recalculate the NPV
    or IRR.

54
Summary
  • The future value of a sum of money is greater
    than the present value because of the interest it
    can earn over time.
  • Future values are found through compounding.
  • Present values are found through discounting.

55
Summary
  • Investments can be analyzed by one or more
    methods
  • Payback period
  • Simple rate of return each has
    advantages
  • Net present value and
    disadvantages
  • Internal rate of return
  • The net cash revenues and the discount rate
    should be on an after-tax basis.
  • The discount rate may need to be adjusted for
    risk and inflation.
  • Financial feasibility analysis is the final step
    in analyzing an investment.
