SUMMARY OF PAPERS
PART 1: capital structure basics
Capital structure: financing investment with:
Internal Capital:
o Retained earnings: own money, no dividend: no fixed cash flow.
Profits not paid back to shareholders, but used to finance
investments, current expenses, etc.
External Capital:
o Debt: usually no voting rights (except in bankruptcy and such),
senior to equity: claim must be paid in full before firm can make
payments to equity holders.
o Equity: no fixed cash flow: receive dividend only after debt holders
claims are satisfied, right to vote at general meeting.
Miller and Merton (1988): Modigliani-Miller Propositions
Assumptions:
1. Perfect financial markets: competitive (individuals and firms are price-
takers: no bargaining, pay for given price), all agents are rational,
frictionless (no transaction costs, no bid-ask price).
2. All agents have same information.
o Lemon markets: seller has more information than buyer. Investors
not able to distinguish; adjust price somewhere in between (more
than bad, cheaper than good). Result: bad companies enter market,
good companies stay out.
Effect is called adverse selection.
o Leads to pecking order theory: information asymmetry between
firm and market makes external finance more costly than internal
funds, debt less costly than equity.
To overcome problem: use retained earnings, then borrow
from debt market (less sensitive to asymmetric information
issues), at last issue equity.
3. Firm’s cash flows don’t depend on financial policy (no bankruptcy costs).
o Cost of financial distress: costs arising from bankruptcy or
distorted business decisions before bankruptcy.
Direct costs: legal and administrative costs.
Indirect costs: impaired ability to conduct business (lost
sales).
Selfish strategy 1: incentive to take large risks.
o Asset substitution: take large risk, invest
more in firm while it’s going bankrupt,
advantage for stockholders.

Expected CF of gamble: 1000 x 0.10 = 100
o Bondholders: 300 x 0.10 = 30
o Stockholders: 1000-300 x 0.10 = 70
100
NPV =−200+ =−116.67
1.20
Expected CF without gamble:
o Bondholders: 200
o Stockholders: 0
, Selfish strategy 2: incentive toward underinvestment:
reject positive NPV projects, because too little cash in
firm (100 extra needed), advantage for bondholders.
o Cost of investment is more than firm has,
stockholders have to supply additional amount.
o Bondholders get paid first, stockholders don’t
see investment back fully.
PV bondholders without project = 200
PV stockholders without project = 0
PV bondholders with project = 300/1.1 =
272.73
PV stockholders with project = 50/1.1 –
100 = -54.55
Selfish strategy 3: milking the property.
o Liquidating dividends: pay out 200 dividend
to shareholders firm insolvent, nothing for
bondholders, plenty for former shareholders
(tactics often violate bond covenants).
o Increase perquisites.
4. No taxes: usually less tax on debt than on equity.
o Efficiency: taxes and subsidies may distort otherwise socially
optimal decisions.
o Financial stability: company may issue too much debt, putting
pressure on banking system.
Debt ×r D ×Tax Rate
PV of Tax Shield= =Debt × Tax Rate
rD
Firm value = value of all equity firm + PV tax shield
MM Propositions: help to focus on real issue, main focus should be investment
(NPV).
MM Proposition I: total market value of firm is independent of its capital
structure. Firm value determined by real assets, capital structure is irrelevant.
Value of firm: present discounted value of future cash flows:
FCF 1 FCF 2
V =E+ D=FCF 0 + + +…
1+ wacc (1+ wacc )2
o Safe stream to bondholders.
o Risky stream to stockholders.
Firm value cannot change total value of securities by splitting cash flows
into two different streams, is determined by real assets, capital structure is
irrelevant.
