What’s the Big Idea?

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.

Shareholder’s Terminal Value

in financial asset

Because stockholders can reinvest the dividend in risky financial assets, the expected return on a capital-budgeting project should be at least as great as the expected return on a financial asset of comparable risk.

A firm with excess cash can either pay a dividend or make a capital investment

The Cost of Equity

From the firm’s perspective, the expected return is

the Cost of Equity Capital:

To estimate a firm’s cost of equity capital, we need to know three things:

The risk-free rate, RF

Example

Suppose the stock of Stansfield Enterprises, a publisher of PowerPoint presentations,

has a beta of 2.5. The firm is 100-percent equity financed.
Assume a risk-free rate of 5-percent and a market risk premium of 10-percent.
What is the appropriate discount rate for an expansion of this firm?

12.2 Estimation of Beta: Measuring Market Risk

Market Portfolio - Portfolio of

all assets in the economy. In practice a broad stock market index, such as the TSE 300 index, is used to represent the market.
Beta - Sensitivity of a stock’s return to the return on the market portfolio.

12.2 Estimation of Beta

Theoretically, the calculation of beta is straightforward:

Problems
Betas may

vary over time.
The sample size may be inadequate.
Betas are influenced by changing financial leverage and business risk.
Solutions
Problems 1 and 2 (above) 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.
Слайд 10

Stability of Beta Most analysts argue that betas are generally stable

Stability of Beta

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.
Changes in product line
Changes in technology
Deregulation
Changes in financial leverage
Слайд 11

Using an Industry Beta

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.

Cyclicality of Revenues Highly cyclical stocks have high betas. Empirical evidence

Cyclicality of Revenues

Highly cyclical stocks have high 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 are not especially dependent upon the business cycle.
Слайд 14

Operating Leverage The degree of operating leverage measures how sensitive a

Operating Leverage

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 cyclicity on beta.
The degree of operating leverage is given by:

Financial Leverage and Beta

Operating leverage refers to the sensitivity to the

firm’s fixed costs of production.
Financial leverage is the sensitivity of a firm’s fixed costs of financing.
The relationship between the betas of the firm’s debt, equity, and assets is given by:

Financial leverage always increases the equity beta relative to the asset beta.

Financial Leverage and Beta: Example

Consider Grand Sport, Inc., which is currently

all-equity 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:

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 company.

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 × [14% – 4%]
This is a breakdown of the company’s investment projects:

1/3 Automotive retailer β = 2.0
1/3 Computer Hard Drive Mfr. β = 1.3
1/3 Electric Utility β = 0.6

average β of assets = 1.3

When evaluating a new electrical generation investment, which cost of capital should be used?

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

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

12.5 Estimating Bombardier’s Cost of Capital

We aim at estimating Bombardier’s cost

of capital, as of June 15, 2001.
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 YTM of the firm’s debt.
Second, we determine the WACC by weighting these two costs appropriately.

What is Liquidity?

The idea that the expected return on a stock

and the firm’s cost of capital are positively related to risk is fundamental.
Recently a number of academics have argued that the expected return on a stock and the firm’s cost of capital are negatively related to the liquidity of the firm’s shares as well.
The trading costs of holding a firm’s shares include brokerage fees, the bid-ask spread, and market impact costs.
Слайд 31

Liquidity, Expected Returns, and the Cost of Capital The cost of

Liquidity, Expected Returns, and the Cost of Capital

The cost of trading

an illiquid stock reduces the total return that an investor receives.
Investors thus will demand a high expected return when investing in stocks with high trading costs.
This high expected return implies a high cost of capital to the firm.

Liquidity and Adverse Selection

There are a number of factors that determine

the liquidity of a stock.
One of these factors is adverse selection.
This refers to the notion that traders with better information can take advantage of specialists and other traders who have less information.
The greater the heterogeneity of information, the wider the bid-ask spreads, and the higher the required return on equity.
Слайд 34

What the Corporation Can Do

The corporation has an incentive to lower

trading costs since this would result in a lower cost of capital.
A stock split would increase the liquidity of the shares.
A stock split would also reduce the adverse selection costs thereby lowering bid-ask spreads.
This idea is a new one and empirical evidence is not yet in.
Слайд 35

What the Corporation Can Do

Companies can also facilitate stock purchases through

the Internet.
Direct stock purchase plans and dividend reinvestment plans handled on-line allow small investors the opportunity to buy securities cheaply.
The companies can also disclose more information, especially to security analysts, to narrow the gap between informed and uninformed traders. This should reduce spreads.
