7.1 Incremental Cash Flows
• Cash flows matter—not accounting earnings.
• Sunk costs don’t matter.
• Incremental cash flows matter.
• Opportunity costs matter.
• Side effects like cannibalism and erosion matter.
• Taxes matter: we want incremental after-tax cash flows.
• Inflation matters.

Cash Flows—Not Accounting Earnings
• Consider depreciation expense.
• You never write a cheque made out to “depreciation.”
• Much of the work in evaluating a project lies in taking accounting numbers and generating cash flows.

Incremental Cash Flows
• Sunk costs are not relevant
– Just because “we have come this far” does not mean that we should continue to throw good money after bad.
• Opportunity costs do matter. Just because a project has a positive NPV does not mean that it should also have automatic acceptance. Specifically if another project with a higher NPV would have to be passed up we should not proceed.
• Side effects matter.
– Erosion and cannibalism are both bad things. If our new product causes existing customers to demand less of current products, we need to recognize that.
7-6

Estimating Cash Flows
• Cash Flows from Operations
– Recall that:
Operating Cash Flow = EBIT – Taxes + Depreciation
• Net Capital Spending
– Don’t forget salvage value (after tax, of course).
• Changes in Net Working Capital
– Recall that when the project winds down, we enjoy a return of net working capital.

Interest Expense
• Later chapters will deal with the impact that the amount of debt that a firm has in its capital structure has on firm value.
• For now, it’s enough to assume that the firm’s level of debt (hence interest expense) is independent of the project at hand.

7.2 The Majestic Mulch and Compost Company (MMCC): An ExampleCosts of test marketing (already spent): $250,000.
The proposed factory site (which we own) has no resale value.
Cost of the tool making machine: $800,000 (CCA calculations are based on a class 8, 20-percent rate).
Production (in units) by year during 8-year life of the machine: 6,000, 9,000, 12,000, 13,000, 12,000, 10,000, 8,000, and 6,000.
Price during first year is $100; price increases 2-percent per year thereafter.
Production costs during first year are $64 per unit and increase at the annual inflation rate of 5-percent per year thereafter.
Fixed production costs are $50,000 each year.
Working capital: initially $40,000, then 15-percent of sales at the end of each year. Falls to $0 by the project’s end.

The Worksheet for Cash Flows of the MMCC
Recall that production (in units) by year during 8-year life of the machine is given by: (6,000, 9,000, 12,000, 13,000, 12,000, 10,000, 8,000, 6,000).
Price during first year is $100 and increases 2% per year thereafter.
Sales revenue in year 5 = 12,000×[$100×(1.02)4] = $1,298,919.
(All cash flows occur at the end of the year.)

Again, production (in units) by year during 8-year life of the machine is given by: (6,000, 9,000, 12,000, 13,000, 12,000, 10,000, 8,000, 6,000).
Variable costs during first year (per unit) are $64 and (increase 5% per year thereafter). Fixed costs are $50,000 each year.
Production costs in year 2 = 12,000×[$64×(1.05)4] + 50,000= $983,509.
(All cash flows occur at the end of the year.)

7.3 Inflation and Capital Budgeting
• Inflation is an important fact of economic life and must be considered in capital budgeting.
• Consider the relationship between interest rates and inflation, often referred to as the Fisher relationship:(1 + Nominal Rate) = (1 + Real Rate) × (1 + Inflation Rate)
• For low rates of inflation, this is often approximated as Real Rate Nominal Rate – Inflation Rate
• While the nominal rate in the U.S. has fluctuated with inflation, most of the time the real rate has exhibited far less variance than the nominal rate.
• When accounting for inflation in capital budgeting, one must compare real cash flows discounted at real rates or nominal cash flows discounted at nominal rates.
7-16
McGraw-Hill Ryerson © 2003 McGraw–Hill Ryerson Limited
Example of Capital Budgeting under Inflation
Canadian Electronics Inc. (CEI) has an investment opportunity to produce a new stereo colour TV.
The required investment on January 1 of this year is $32 million. CCA calculations are based on a class 8, 20% rate. The firm is in the 34% tax bracket.
This investment will have no resale value at the end of the project (in four years).
The price of the product on January 1 will be $400 per unit. The price will stay constant in real terms.
Labour costs will be $15 per hour on January 1. The will increase at 2% per year in real terms.
Energy costs will be $5 per TV; they will increase 3% per year in real terms.
The inflation rate is 5%.
Revenues are received and costs are paid at year-end.
7-17
McGraw-Hill Ryerson © 2003 McGraw–Hill Ryerson Limited
Example of Capital Budgeting under Inflation
The riskless nominal discount rate is 4%. The real discount rate for costs and revenues is 8%. Calculate the NPV.

adjustment for
– the 1st year 50-percent rule

Example of Capital Budgeting under Inflation
The project NPV can now be computed as the sum of the PV of the cost, the PV of the risky cash flows discounted at the risky rate, and the PV of the risk-free CCA tax shield cash flows discounted at the risk-free discount rate.
NPV = -$32,000,000 + $69,590,868 + $8,892,308 = $46,483,176

7.4 Investments of Unequal Lives: The Equivalent Annual Cost Method• There are times when application of the NPV rule can lead
to the wrong decision. Consider a factory that must have an air cleaner. The equipment is mandated by law, so there is no “doing without.”
• There are two choices:
– The “Cadillac cleaner” costs $4,000 today, has annual operating costs of $100 and lasts for 10 years.
– The “cheaper cleaner” costs $1,000 today, has annual operating costs of $500 and lasts for five years.
• Which one should we choose?

Investments of Unequal Lives
• Replacement Chain
– Repeat the projects forever, find the PV of that perpetuity.
– Assumption: Both projects can and will be repeated.
• Matching Cycle
– Repeat projects until they begin and end at the same time—like we just did with the air cleaners.
– Compute NPV for the “repeated projects.”
• The Equivalent Annual Cost Method

McGraw-Hill Ryerson © 2003 McGraw–Hill Ryerson Limited
Investments of Unequal Lives: EAC• The Equivalent Annual Cost Method
– Applicable to a much more robust set of circumstances than replacement chain or matching cycle.
– The Equivalent Annual Cost is the value of the level payment annuity that has the same PV as our original set of cash flows.
– NPV = EAC × ArT
– For example, the EAC for the Cadillac air cleaner is $750.98

Consider a Belgian Dentist’s office; he needs an autoclave to sterilize his instruments. He has an old one that is in use, but the maintenance costs are rising and so he is considering replacing this indispensable piece of equipment.
New Autoclave– Cost = $3,000 today, – Maintenance cost = $20 per year– Resale value after 6 years = $1,200– NPV of new autoclave (at r = 10%):

Note that the total cost of keeping an autoclave for the first year includes the $200 maintenance cost as well as the opportunity cost of the foregone future value of the $900 we didn’t get from selling it in year 0 less the $850 we have if we still own it at year 1.

7.5 Summary and Conclusions
• Capital budgeting must be placed on an incremental basis.
– Sunk costs are ignored
– Opportunity costs and side effects matter
• Inflation must be handled consistently
– Discount real flows at real rates
– Discount nominal flows at nominal rates
• When a firm must choose between two machines of unequal lives:
– the firm can apply either the matching cycle approach
– or the equivalent annual cost approach
