Title: Investment Analysis (Chapter 17)
1Investment Analysis(Chapter 17)
2Objectives
- 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.
3Investment 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!
4Time 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.
5Why 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
6Future 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.
7Present 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!
8Payment(PMT)
- The amount of money to be paid or received at the
end of each of a number of time periods.
9Interest 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?
10Time 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).
11Annuity
- A series of equal periodic payments.
- Receipts
- Expenditures
- Now lets look more carefully at the concepts of
future and present value.
12Future 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.
13Future 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).
14Future 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
15Future 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
16Rule 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)
17Future 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.
18Future 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
19FV for a Present Sum and for an Annuity
FV for a single payment FV of
an annuity
20Present 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.
21Present 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.
22Relationship Between Compounding Discounting
Compounding (FV)
Discounting (PV)
23Present 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.
24Present 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. -
25Present 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
26Powerball 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.
27Present 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

PV for a single payment
PV for an annuity
29Some 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!
30Investment 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.
31Investment Analysis
- Payback Period
- Simple Rate of Return
- Net Present Value
- Internal Rate of Return
32Investment 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.
33Investment 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.
34Investment 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).
35Investment 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.
36Investment 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.
37Investment Analysis
- Simple Rate of Return (RR)
- Strength
- Considers an investments earnings over its
entire life. - Weakness
- Ignores the size and timing of earnings.
38Investment 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 -

- Example 1
- Cost of investment 10,000.
- Net cash revenue 2,500 year for 6 years
- Discount rate 8.

41Investment 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.
42Investment 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.
43Investment 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.
44Estimation of IRR
Example from textbook
45Investment 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.
46Financial 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?
47Financial 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.
48Financial 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.
49Income 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
50Inflation
- 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.
51Inflation
- 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.
52Risk
- 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.
53Sensitivity 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.
54Summary
- 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.
55Summary
- 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.
