Excel Features: Linear Regression
Linear regression finds the line that best fits a series of points. In finance, it is often used to find the beta ( b ) of a firm’s equity.
In our example, we shall find the beta of MMM using the S&P 500 as a proxy for the market.
Since we want to know the sensitivity of the return on MMM to changes in the return on the
S&P 500, the return on MMM is the dependent variable (y axis) and the return on the S&P 500 the independent variable (x-axis).

17
Rate of return that the suppliers of capital – bondholders and stockholders require as compensation for their contributions of capital
18
As firms take on more debt, financial leverage increases increasing the riskiness of the firm and causing lenders to require a greater return
Additional debt may therefore increase cost of capital
The marginal cost is the cost to raise the additional funds for the potential investment project
19
Cost of capital for entire company
Important for firm/security valuation
Cost of capital for a specific project
WACC must be adjusted for the riskiness of the project

Earlier chapters on capital budgeting focused on the appropriate size and timing of cash flows.
This chapter discusses the appropriate discount rate when cash flows are risky.

Asset Betas and Project Discount
Rates
When a firm uses no leverage, its equity beta equals its asset beta.
An unlevered beta simply tells us how risky the equity of a company might be if it used no leverage at all.

When an all-equity firm invests in an asset similar to its existing assets, the cost of equity is the appropriate discount rate to use in NPV calculations.
When a firm with both debt and equity invests in an asset similar to its existing assets, the
WACC is the appropriate discount rate to use in NPV calculations.

An all-equity firm should accept projects whose IRRs exceed the cost of equity capital and reject projects whose IRRs fall short of the cost of capital.
Market Portfolio - Portfolio of all assets in the market. In practice, a broad stock market index, such as the S&P Composite, is used to represent or proxy the market.
Beta - Sensitivity of a stock’s return to the return on the market portfolio.
• Problems
1. Betas may vary over time.
2. The sample size may be inadequate.
3. Betas are influenced by changing financial leverage and business risk.
• Solutions
– Problems 1 and 2 can be moderated by more sophisticated statistical techniques.
– Problem 3 can be lessened by adjusting for changes in business and financial risk.
– Look at average beta estimates of comparable firms in the industry.
Most analysts argue that betas are generally stable for firms remaining in the same industry.
That’s not to say that a firm’s beta can’t change due to …
Changes in production
Changes in operating leverage
Deregulation
Changes in financial leverage
It is frequently argued that one can better estimate a firm’s beta by involving the whole industry.
If you believe that the operations of the firm are similar to the operations of the rest of the industry, you should use the industry beta.
If you believe that the operations of the firm are fundamentally different from the operations of the rest of the industry, you should use the firm’s beta.
Don’t forget about adjustments for financial leverage.
Business Risk
Cyclicality of Revenues
Operating Leverage
Financial Risk
Financial Leverage
Highly cyclical stocks have higher betas.
Empirical evidence suggests that retailers and automotive firms fluctuate with the business cycle.
Transportation firms and utilities are less dependent upon the business cycle.
Note that cyclicality is not the same as variability – stocks with high standard deviations need not have high betas.
Movie studios have revenues that are variable, depending upon whether they produce “hits” or “flops,” but their revenues may not especially dependent upon the business cycle.
The degree of operating leverage measures how sensitive a firm (or project) is to its fixed costs.
Operating leverage increases as fixed costs rise and variable costs fall.
Operating leverage magnifies the effect of cyclicality on beta.
The degree of operating leverage is given by:

Operating leverage refers to the sensitivity to the firm’s fixed costs of production.
Financial leverage is the sensitivity to a firm’s fixed costs of financing.

• Financial leverage always increases the equity beta relative to the asset beta.
Consider Grand Sport, Inc., which is currently all-equity financed and has a beta of 0.90.
The firm has decided to lever up to a capital structure of 1 part debt to 1 part equity.
Since the firm will remain in the same industry, its asset beta should remain 0.90.
However, assuming a zero beta for its debt, its equity beta would become twice as large: b

= 2 × 0.90 = 1.80
The Firm versus the Project
Any project’s cost of capital depends on the use to which the capital is being put –not the source.
Therefore, it depends on the risk of the project and not the risk of the firm.

A firm that uses one discount rate for all projects may over time increase the risk of the firm while decreasing its value. Why?
Capital Budgeting & Project Risk
Suppose the Conglomerate Company has a cost of capital, based on the
CAPM, of 17%. The risk-free rate is 4%, the market risk premium is 10%, and the firm’s beta is 1.3.
17% = 4% + 1.3 × 10%
This is a breakdown of the company’s investment projects:
1/3 Automotive Retailer b
= 2.0
1/3 Computer Hard Drive Manufacturer b
= 1.3
1/3 Electric Utility b
= 0.6
average b of assets = 1.3
When evaluating a new electrical generation investment, which cost of capital should be used?

Investments in hard drives or auto retailing should have higher discount rates.

r = 4% + 0.6

10% reflects the opportunity cost of capital on an investment in electrical generation, given the unique risk of the project.

• Because interest expense is deductable, we multiply the last term by (1 – t
C
).
First, we estimate the cost of equity and the cost of debt.
We estimate an equity beta to estimate the cost of equity.
We can often estimate the cost of debt by observing the return on the firm’s debt.
Second, we determine the WACC by weighting these two costs appropriately.
The industry average beta is 0.82, the risk free rate is 3%, and the market risk premium is 8.4%.
Thus, the cost of equity capital is:
i

This is International’s cost of capital. It should be used to discount any project where one believes that the project’s risk is equal to the risk of the firm as a whole and the project has the same leverage as the firm as a whole.
