Capital budeting decisions with the Net Present Value rule1. Foundations Professor André Farber Solvay Business School University of Brussels, Belgium Hanoi April 2000
Time value of money: introduction • Consider simple investment project: • Interest rate r = 10% 121 1 0 -100 Hanoi April 2000
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 future value +121 +100 0 1 -100 -110 Hanoi April 2000
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 +121 +110 -100 -121 Hanoi April 2000
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 Hanoi April 2000
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 Hanoi April 2000
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% IRR: a general definition Hanoi April 2000
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 a market price Hanoi April 2000
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 Hanoi April 2000
NPV calculation - example • Suppose r = 10% Hanoi April 2000
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 Hanoi April 2000
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% Hanoi April 2000
NPV Profiles Hanoi April 2000
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
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
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 Hanoi April 2000
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 Hanoi April 2000
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
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
Interest-bearing debt: definition • + Long-term debt • + Current maturities of long term debt • + Notes payable to banks Hanoi April 2000
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: DSE = STOCK ISSUE + RETAINED EARNINGS = SI + NET INCOME - DIVIDENDS DFA = INVESTMENT - DEPRECIATION • (INV - DEP) + WCR + CASH = (SI + NI - DIV) + D Hanoi April 2000
(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
Free cash flow • FCF = (NI +DEP - WCR) - (INV) • = CFop + CFinv • From the statement of cash flows • FCF = - (SI + D - DIV) + CASH Hanoi April 2000
Understanding FCF CF from operation + CF from investment + CF from financing = CASH Cash flow from operation Cash flow from financing Cash flow from investment Cash Hanoi April 2000
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% Hanoi April 2000
Scenario 1: no inflation Hanoi April 2000
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 Hanoi April 2000
Scenario 2 : Inflation = 100% Nominal discount rate: (1+10%) x (1+100%) = 2.20 Nominal rate = 120% NPV now negative. Why? Hanoi April 2000
