Capital budeting decisions with the Net Present Value rule1. Foundations
Professor André Farber
Solvay Business School
University of Brussels, Belgium
Hanoi April 2000 2
Time value of money: introduction
• Consider simple investment project:
• Interest rate r = 10%
121
-100
0 1

Net future value
• NFV = +121 - 100 1.10 = 11
• = + C1 - I (1+r)
• Decision rule: invest if NFV>0
• Justification: takes into cost of capital
– cost of financing
– opportunity cost

Net Present Value
• NPV = - 100 + 121/1.10 = + 10
• = - I + C1/(1+r)
• = - I + C1 DF1
• DF1 = 1-year discount factor
• a market price
• C1 DF1 =PV(C1)
• Decision rule: invest if NPV>0
• NPV>0 NFV>0

Internal Rate of Return
• Alternative rule: compare the internal rate of return for the project to the opportunity cost of capital
• Definition of the Internal Rate of Return IRR : (1-period)
IRR = (C1 - I)/I
• In our example: IRR = (121 - 100)/100 = 21%
• The Rate of Return Rule: Invest if IRR > r

IRR versus NPV
• In this simple setting, the NPV rule and the Rate of Return Rule lead to the same decision:
• NPV = -I+C1/(1+r) >0
C1>I(1+r)
• (C1-I)/I>r
IRR>r

IRR: a general definition
• The Internal Rate of Return is the discount rate such that the NPV is equal to zero.
• -I + C1/(1+IRR) 0
• In our example:
• -100 + 121/(1+IRR)=0
• IRR=21% -25.0-20.0
-15.0-10.0

Extension to several periods
• Investment project: -100 in year 0, + 150 in year 5.
• Net future value calculation:
NFV5 = +150 - 100 (1.10)5 = +150 - 161 = -11 <0
Compound interest
• Net present value calculation:
NPV = - 100 + 150/(1.10)5
= - 100 + 150 0.621 = - 6.86
0.621 is the 5-year discount factor DF5 = 1/(1+r)5

NPV: general formula
• Cash flows: C0 C1 C2 … Ct … CT
• t-year discount factor: DFt = 1/(1+r)t
• NPV = C0 + C1 DF1 + … + Ct DFt + … + CT DFT

IRR in multiperiod case
• Reinvestment assumption: the IRR calculation assumes that all future cash flows are reinvested at the IRR
• Disadvantages:– Does not distinguish between investing and financing– IRR may not exist or there may be multiple IRR – Problems with mutually exclusive investments
• Advantages:– Easy to understand and communicate

IRR and NPV - Example
Compute the IRR and NPV for the following two projects. Assume the required return is 10%.
Year Project A Project B
0 -$200 -$150
1 $200 $50
2 $800 $100
3 -$800 $150
NPV 42 91
IRR 0%, 100% 36%

The Payback Period Rule
• How long does it take the project to “pay back” its initial investment?
• Payback Period = # of years to recover initial costs
• Minimum Acceptance Criteria: set by management
• Ranking Criteria: set by management
Hanoi April 2000 15
The Payback Period Rule (continued)
• Disadvantages:– Ignores the time value of money
– Ignores CF after payback period
– Biased against long-term projects
– Payback period may not exist or multiple payback periods
– Requires an arbitrary acceptance criteria
– A project accepted based on the payback criteria may not have a positive NPV
• Advantages:– Easy to understand
– Biased toward liquidity
Hanoi April 2000 16
The Profitability Index (PI) Rule
• PI = Total Present Value of future CF’s / Initial Investment
• Minimum Acceptance Criteria: Accept if PI > 1
• Ranking Criteria: Select alternative with highest PI
• Disadvantages:
– Problems with mutually exclusive investments
• Advantages:
– May be useful when available investment funds are limited
– Easy to understand and communicate
– Correct decision when evaluating independent projects

Incremental Cash Flows
• Cash, Cash, Cash, CASH
• Incremental
– Sunk Costs
– Opportunity Costs
– Side Effects
• Tax and Inflation
• Estimating Cash Flows
– Cash flows from operation
– Net capital spending
– Changes in net working capital
• Interest Expense

Summarized balance sheet
• Assets• Fixed assets (FA)
• Working capital requirement (WCR)
• Cash (Cash)
• Liabilities• Stockholders' equity (SE)
• Interest-bearing debt (D)
• FA + WCR + Cash = SE + D
Hanoi April 2000 19
Working capital requirement : definition
• + Accounts receivable
• + Inventories
• + Prepaid expenses
•
• - Account payable
• - Accrued payroll and other expenses
• (WCR sometimes named "operating working capital")
– Copeland, Koller and Murrin Valuation: Measuring and Managing the Value of Companies, 2d ed. John Wiley 1994
Hanoi April 2000 20
Interest-bearing debt: definition
• + Long-term debt
• + Current maturities of long term debt
• + Notes payable to banks
Hanoi April 2000 21
The Cash Flow Statement
• Let us start from the balance sheet identity:
– FA + WCR + CASH = SE + D
• Over a period: FA + WCR + CASH = SE + D
• But:
SE = STOCK ISSUE + RETAINED EARNINGS
= SI + NET INCOME - DIVIDENDS
FA = INVESTMENT - DEPRECIATION
• (INV - DEP) + WCR + CASH = (SI + NI - DIV) + D
Hanoi April 2000 22
• (NI +DEP - WCR) - (INV) + (SI + D - DIV) = CASH • Net cash flows from
• operating activities (CFop)
• • Cash flow from
• investing activities (CFinv)
• • Cash flow from
• financing activities (CFfin)
Hanoi April 2000 23
Free cash flow
• FCF = (NI +DEP - WCR) - (INV)
• = CFop + CFinv
• From the statement of cash flows
• FCF = - (SI + D - DIV) + CASH
Hanoi April 2000 24
Understanding FCF
CF from operation + CF from investment + CF from financing = CASHCF from operation + CF from investment + CF from financing = CASH
Cash flow from operation
Cash flow from investment
Cash flow from financing

NPV calculation: example
• Length of investment : 2 years
• Investment : 60 (t = 0)
• Resale value : 20 (t = 3, constant price)
• Depreciation : linear over 2 years
• Revenue : 100/year (constant price)
• Cost of sales : 50/year (constant price) WCR/Sales : 25%
• Real discount rate : 10%
• Corporate tax rate : 40%

Inflation
• Use nominal cash flow
• Use nominal discount rate
• Nominal versus Real Rate (The Fisher Relation)(1 + Nominal Rate) = (1 + Real Rate) x (1 + Inflation Rate)
• Example:
• Real cash flow year 1 = 110
• Real discount rate = 10%
• Inflation = 20%
• Nominal cash flow = 110 x 1.20
• Nominal discount rate = 1.10 x 1.20 - 1
• NPV = (110 x 1.20)/(1.10 x 1.20) = 110/1.10 = 100
