Cost of Capital

Cost of Capital - The return the firm’s
investors could expect to earn if they
invested in securities with comparable
degrees of risk

Capital Structure - The firm’s mix of
long term financing and equity financing

Cost of Capital

The cost of capital represents the overall cost
of financing to the firm

The cost of capital is normally the relevant
discount rate to use in analyzing an
investment

The overall cost of capital is a weighted
average of the various sources:

WACC = Weighted Average Cost of Capital

WACC = After-tax cost x weights

Cost of Debt

The cost of debt to the firm is the effective yield
to maturity (or interest rate) paid to its
bondholders

Since interest is tax deductible to the firm, the
actual cost of debt is less than the yield to
maturity:

After-tax cost of debt = yield x (1 - tax rate)

The cost of debt should also be adjusted for
flotation costs (associated with issuing new
bonds)

Prescott Corporation issues a

20 year

bond paying the market

rate of

10%.

Coupons are annual.

The bond will sell for par since it pays

the market rate, but flotation costs

amount to

$50

per bond.

What is the pre-tax and after-tax cost

of debt for Prescott Corporation?

Cost of Equity:
Retained Earnings

Why is there a cost for retained
earnings?

Earnings can be reinvested or paid out
as dividends

Investors could buy other securities,
and earn a return.

Thus, there is an opportunity cost if
earnings are retained

Cost of Equity:
Retained Earnings

Common stock equity is available through
retained earnings (R/E) or by issuing new
common stock:

Common equity = R/E + New common

stock

Cost of Equity:
New Common Stock

The cost of new common stock is
higher than the cost of retained
earnings because of flotation costs

(such as sales commissions) for
the new securities

Dividend Growth Model

This model has drawbacks:

Some firms concentrate on growth and do

not pay dividends at all, or only irregularly

Growth rates may also be hard to estimate

Also this model doesn’t adjust for market

risk

Therefore many financial managers prefer

the capital asset pricing model (CAPM) - or

security market line (SML) - approach for

estimating the cost of equity

CAPM/SML approach

Advantage: Evaluates risk, applicable
to firms that don’t pay dividends

Disadvantage: Need to estimate

the risk premium (usually based on past
data, not future projections)

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 WIG, is used to
represent the market

Beta - sensitivity of a stock’s return to
the return on the market portfolio

Estimation of Beta

Theoretically, the calculation of beta is

straightforward:

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 (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.

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

Changes in financial leverage

What is the appropriate risk-
free rate?

Use the yield on a long-term bond if you are
analyzing cash flows from a long-term investment

For short-term investments, it is entirely
appropriate to use the yield on short-term
government securities

Use the nominal risk-free rate if you discount
nominal cash flows and real risk-free rate if you
discount real cash flows

Weighted Average Cost of Capital
(WACC)

WACC weights the cost of equity and the
cost of debt by the percentage of each
used in a firm’s capital structure

WACC=(E/ V) x R

E

+ (D/ V) x R

D

x (1-T

C

)

(E/V)= Equity % of total value

(D/V)=Debt % of total value

(1-Tc)=After-tax % or reciprocal of corp tax rate
Tc. The after-tax rate must be considered
because interest on corporate debt is deductible

WACC Illustration

ABC Corp has 1.4 million shares common valued at
$20 per share =$28 million. Debt has face value of
$5 million and trades at 93% of face ($4.65 million)
in the market. Total market value of both equity +
debt thus =$32.65 million. Equity % = .8576 and
Debt % = .1424

Risk free rate is 4%, risk premium=7% and ABC’s
β=.74

Return on equity per SML : R

E

= 4% + (7% x .

74)=9.18%

Tax rate is 40%

Current yield on market debt is 11%

Final notes on WACC

WACC should be based on market rates and

valuation, not on book values of debt or

equity

Book values may not reflect the current

marketplace

WACC will reflect what a firm needs to earn

on a new investment. But the new

investment should also reflect a risk level

similar to the firm’s Beta used to calculate

the firm’s R

E

.

In the case of ABC Co., the relatively low WACC of

8.81% reflects ABC’s β=.74. A riskier investment

should reflect a higher interest rate.

Final notes on WACC

The WACC is not constant

It changes in accordance with the
risk of the company and with the
floatation costs of new capital

The End ….

KAPITAŁ - bogactwo zebrane uprzednio w celu podjęcia dalszej produkcji

(F. Quesnay, XVIII)

wszelki wynik procesu produkcyjnego, który przeznaczony jest do

późniejszego wykorzystania w procesie produkcyjnym (MCKenzzie,

Nardelli,1991)

całokształt zaangażowanych w przedsiębiorstwie wewnętrznych i

zewnętrznych, własnych i obcych, terminowych i nieterminowych

zasobów (bilans)

STRUKTURA KAPITAŁU

proporcja udziału kapitału własnego i obcego w finansowaniu działalności

przedsiębiorstwa

relacja wartości zadłużenia długoterminowego do kapitałów własnych

przedsiębiorstwa

struktura finansowania – struktura kapitału = zobowiązania

bieżące

ramy statycznego kompromisu, w którym przedsiębiorstwo ustala

docelową wielkość wskaźnika zadłużenia i stopniowo zbliża się do jego

osiągnięcia.
