What have we learned in the
last lecture


In the last lecture, we have discussed
the case in the end of chapter 12, what
have you learned from this case?
In the last lecture, we have also
discussed three forms of market
efficiency, what are they and what is your
understanding of these three forms of
market efficiency?

Capital structure


Capital structure refers to the mix of debt and
equity in a firm.
We often use D/E or D/V (V=D+E) to indicate
the capital structure of a firm.
•

Usually, the higher the ratio, the more debt a firm has
The capital structure problem for a firm is to
determine what is the maximum amount of
debt a firm should have to maximize the firm’s
value.

Does capital structure affect
the firm value?

MM’s proposition 1

Modigliani & Miller
• If the investment opportunity is fixed,
there
are no taxes, and capital markets function
well, the market value of a company does not
depend on its capital structure.

How can we understand this?
• The size of a pizza has nothing to do with how
you slice it.
Financial management: lecture 10
MM’s proposition 2

Modigliani & Miller
• If the investment opportunity is fixed,
•
there
are no taxes, and capital markets function
well, the expected rate of return on the
common stock of a levered firm increases in
proportion to the debt-equity ratio (D/E),
expressed in market values.
The WACC is independent of how the firm is
financed

Capital structure and Corporate
Taxes

The use of debt has a lot of implications:
•
•
Financial risk- The use of debt will increase the risk to
share holders and thus Increase the variability of
shareholder returns.
Interest tax shield- The savings resulting from
deductibility of interest payments.
Financial management: lecture 10
An example on Tax shield
You own all the equity of Space Babies Diaper
Co.. The company has no debt. The company’s
annual cash flow is $1,000, before interest and
taxes. The corporate tax rate is 40%. You have
the option to exchange 1/2 of your equity position
for 10% bonds with a face value of $1,000.
Should you do this and why?

Capital Structure and tax shield
PV of Tax Shield =
D x rD x Tc
rD
= D x Tc
Example:
Tax benefit = 1000 x (.10) x (.40) = $40
PV of 40 perpetuity = 40 / .10 = $400
PV Tax Shield = D x Tc = 1000 x .4 = $400
Financial management: lecture 10
MM’s proposition 1 with tax

firm value = value of all equity firm + PV(tax
shield)
Example,
all equality firm value =600/0.1=6,000
PV( tax shield)=400
firm value=6,400
Financial management: lecture 10
MM’s proposition 2

The weighted average cost of capital is
decreasing with the ratio of D/E, that is
 D 
 E 

Optimal Capital structure
Trade-off Theory - Theory that capital structure
is based on a trade-off between tax savings
and distress costs of debt.
Pecking Order Theory - Theory stating that
firms prefer to issue debt rather than equity if
internal finance is insufficient.
