Treatment of Financing Costs
Should you subtract interest expense or dividends when calculating CF?
NO.
We discount project cash flows with a cost of capital that is the rate of return required by all investors (not just debtholders or stockholders), and so we should discount the total amount of cash flow available to all investors.
They are part of the costs of capital. If we subtracted them from cash flows, we would be double counting capital costs.

Sunk Costs
Suppose $100,000 had been spent last year to improve the production line site. Should this cost be included in the analysis?
NO. This is a sunk cost. Focus on incremental investment and operating cash flows.

Incremental Costs
Suppose the plant space could be leased out for $25,000 a year. Would this affect the analysis?
Yes. Accepting the project means we will not receive the $25,000. This is an opportunity cost and it should be charged to the project.
A.T. opportunity cost = $25,000 (1 – T) = $15,000 annual cost.

Externalities
If the new product line would decrease sales of the firm’s other products by $50,000 per year, would this affect the analysis?
Yes. The effects on the other projects’ CFs are “externalities.”
Net CF loss per year on other lines would be a cost to this project.
Externalities will be positive if new projects are complements to existing assets, negative if substitutes.

Why is it important to include inflation when estimating cash flows?
Nominal r > real r. The cost of capital, r, includes a premium for inflation.
Nominal CF > real CF. This is because nominal cash flows incorporate inflation.
If you discount real CF with the higher nominal r, then your NPV estimate is too low.

Inflation (Continued)
Nominal CF should be discounted with nominal r, and real CF should be discounted with real r.
It is more realistic to find the nominal CF (i.e., increase cash flow estimates with inflation) than it is to reduce the nominal r to a real r.

What if you terminate a project before the asset is fully depreciated?
Basis = Original basis – Accum. deprec.
Taxes are based on difference between sales price and tax basis.
| Cash flow from sale | = | Sale proceeds | – | Taxes paid |
© 2020 Cengage Learning. All Rights Reserved. May not be copied, scanned, or duplicated, in whole or in part, except for use as permitted in a license distributed with a certain product or service or otherwise on a password-protected website for classroom use.
Example: If Sold After 3 Years for $25 ($ thousands)
Original basis = $240.
After 3 years, basis = $17.8 remaining.
Sales price = $25.
Gain or loss = $25 – $17.8 = $7.2.
Tax on sale = 0.25($7.2) = $1.80.
Cash flow = Sales price – taxes
Cash flow = $25 – $1.80 = $23.2.

Example: If Sold After 3 Years for $10 ($ thousands)
Original basis = $240.
After 3 years, basis = $17.8 remaining.
Sales price = $10.
Gain or loss = $10 – $17.8 = -$7.8.
Tax on sale = 0.25(-$7.8) = -$1.95.
Cash flow = sales price – taxes paid on sale
Cash flow = $10 – (-$1.95) = $11.95.
Sale at a loss provides a tax credit, so cash flow is larger than sales price!

Calculator Solution
Enter positive CFs in CFLO. Enter I/YR = 10. Solve for NPV = 326,592.77.
Now use TVM keys: PV = -326,592.77, N = 4, I/YR = 10; PMT = 0; Solve for FV = 478,164.47. (This is TV of inflows)
Use TVM keys: N = 4; FV = 478,164.47; PV = -264,000; PMT= 0; Solve for I/YR = 16.0%.
MIRR = 16.0%.

What does “risk” mean in capital budgeting?
Uncertainty about a project’s future profitability.
Measured by σNPV, σIRR, beta.
Will taking on the project increase the firm’s and stockholders’ risk?

Is risk analysis based on historical data or subjective judgment?
Can sometimes use historical data, but generally cannot.
So risk analysis in capital budgeting is usually based on subjective judgments.

Stand-Alone Risk
The project’s risk if it were the firm’s only asset and there were no shareholders.
Ignores both firm and shareholder diversification.
Measured by the σ or CV of NPV, IRR, or MIRR.

Corporate Risk
Reflects the project’s effect on corporate earnings stability.
Considers firm’s other assets (diversification within firm).
Depends on project’s σ, and its correlation, ρ, with returns on firm’s other assets.
Measured by the project’s corporate beta.

Market Risk
Reflects the project’s effect on a well-diversified stock portfolio.
Takes account of stockholders’ other assets.
Depends on project’s σ and correlation with the stock market.
Measured by the project’s market beta.

How is each type of risk used? (1 of 2)
Market risk is theoretically best in most situations.
However, creditors, customers, suppliers, and employees are more affected by corporate risk.
Therefore, corporate risk is also relevant.

How is each type of risk used? (2 of 2)
Stand-alone risk is easiest to measure, more intuitive.
Core projects are highly correlated with other assets, so stand-alone risk generally reflects corporate risk.
If the project is highly correlated with the economy, stand-alone risk also reflects market risk.

What is sensitivity analysis?
Shows how changes in a variable such as unit sales affect NPV or IRR.
Each variable is fixed except one. Change this one variable to see the effect on NPV or IRR.
Answers “what if” questions, e.g. “What if sales decline by 30%?”

Results of Sensitivity Analysis
Steeper sensitivity lines show greater risk. Small changes result in large declines in NPV.
The cost line per unit line is steepest.
Unit sales line is also steep, but not as steep as the cost per unit line.
Salvage line is flat.
Managers should focus on costs and sales demand.

What are the weaknesses of sensitivity analysis?
Does not reflect diversification.
Says nothing about the likelihood of change in a variable, i.e. a steep sales line is not a problem if sales won’t fall.
Ignores relationships among variables.

Are there any problems with scenario analysis?

Assumes that inputs are perfectly correlated—all “bad” values occur together and all “good” values occur together.
Focuses on stand-alone risk, although subjective adjustments can be made.

What are the disadvantages of simulation? (2 of 2)
Sensitivity, scenario, and simulation analyses do not provide a decision rule. They do not indicate whether a project’s expected return is sufficient to compensate for its risk.
Sensitivity, scenario, and simulation analyses all ignore diversification. Thus they measure only stand-alone risk, which may not be the most relevant risk in capital budgeting.

If the firm’s average project has a CV of 0.2 to 0.4, is this a high-risk project? What type of risk is being measured?
CV from scenarios = 1.43, CV from simulation = 1.65. Both are > 0.4, this project has high risk.
CV measures a project’s stand-alone risk.
High stand-alone risk usually indicates high corporate and market risks.

With a 3% risk adjustment, should our project be accepted?
Project r = 10% + 3% = 13%.
That’s 30% above base r.
NPV = $41,584.
Project remains acceptable after accounting for differential (higher) risk.

Should subjective risk factors be considered?
Yes. A numerical analysis may not capture all of the risk factors inherent in the project.
For example, if the project has the potential for bringing on harmful lawsuits, then it might be riskier than a standard analysis would indicate.

What is a real option?
Real options exist when managers can influence the size and risk of a project’s cash flows by taking different actions during the project’s life in response to changing market conditions.
Alert managers always look for real options in projects.
Smarter managers try to create real options.
