Capital Structure
Basic concepts: no taxes
Chapter 15 Capital Structure: Basic Concepts
Capital-structure and pie theory
No-arbitrage pricing.
Example: shares for debt
Value
Required return on the levered firm.
Financial Leverage, EPS, and ROE
Current Proposed
Assets $20,000 $20,000
Debt $0 $8,000
Equity $20,000 $12,000
Debt/Equity 0.00 0.67
Interest rate n/a 8%
Shares 400 240
Share price $50 $50
Comments
Straight swap of equity for debt Market prices unchanged Real asset unchanged
Financial leverage and risk
Three states: bust, normal, boom. Probabilities not explicit. Look at each state separately.
EPS, ROE, Current Structure
Shares Outstanding = 400
Bust Normal Boom
EBIT $1,000 $2,000 $3,000
Interest 0 0 0
Net income $1,000 $2,000 $3,000
EPS $2.50 $5.00 $7.50
ROA 5% 10% 15%
ROE 5% 10% 15%
EPS and ROE under Proposed Capital Structure
Shares Outstanding = 240
Bust Normal Boom
EBIT $1,000 $2,000 $3,000
Interest 640 640 640
Net income $360 $1,360 $2,360
EPS $1.50 $5.67 $9.83
ROA 5% 10% 15%
ROE 3% 11% 20%
Find the point of equal EPS
For understanding the situation, not because it is a key to anything.
Let x = EBIT Solve x/400 = (x - 640)/240 Solution x = 1600. EPS = 4 per share, in either structure

No Debt
Break-even Point
Modigliani-Miller (MM) Model
Perpetual Cash Flows (convenient) Firms and investors can borrow and
lend at the same rate (convenient) Only value matters No transaction costs (convenient) No taxes
Homemade is a big concept
What financial managers do in the firm…
can be duplicated by investors in the market …
if they want to. Implication: financial managers can’t
raise value by restructuring.
Homemade leverage
Instead of the firm swapping equity for debt.
The investor does it himself, by borrowing.
It works out just as well.
Borrow $8000, buy the unlevered firm for $20,000
Bust Normal Boom
Earnings $1000 $2000 $3000
Interest at 8% $640 $640 $640
Net Profits $360 $1360 $2360
ROE (on $12K) 3% 11% 20%
Same as owning the levered firm
Okay, don’t buy the whole firm
Buy 10%, forty shares for $2000. Borrow $800. Total cost $1200 Same as having 10% of the levered
firm, that is, 24 shares at $50 per share.
Homemade annihilation of leverage
Idea. Form a portfolio. Part lending… part the levered firm. Portfolio has the action of the unlevered
firm. A levered firm is a portfolio.
Buy the levered firm (240 shares) and lend 8000
Cost of Portfolio = 12000 + 8000 = 20000
Boom Normal Bust
EPS $1.50 $5.67 $9.83
Earnings $360 $1360 $2360
Interest at (8%) $640 $640 $640
Net cash flow $1000 $2000 $3000
ROE 5% 10% 15%
(Net cash flow / $2,000)
The firm is a veil
A way for shareholders to hold a portfolio.
The MM Propositions I & II (No Taxes)
P1: Value is unaffected by leverage P1: VL = VU
P2: Leverage increases the risk and return to stockholders(formula to follow)
Proposition II of M-M
rB is the interest rate
rs is the return on (levered) equity r0 is the return on unlevered equity
B is value of debt SL is value of levered equity
rs = r0 + (B / SL) (r0 - rB)
Quick derivation of MM II
Uses MM I. Value unchanged. Uses cash flow constraint.
Value Random cash flow
A a
B b
Va+b a+b
Va+b = A + B
No arbitrage pricing.
Suppose Va+b not equal to A + B.
Suppose Va+b > A + B.
The potential arbitrage is to buy a and b separately and then sell a+b as a unit.
Gain = Va+b - A – B, which is > 0.
Position a + b – (a+b) = 0 is riskless
Complete markets
Cash flows a and b must be tradable.
e.g., not gambling debts
e.g., not insurance contracts
Value Random cash flow
Shares SL sL
Bonds B b
Unlevered firm SU sU = sL + b
For instance, capital structure
Conclusion: SU= SL + B
Problem: market rate of return on levered shares
Increased risk of levered shares. Solution using definition of rates of
return and MM I.

Weighted average cost of capital
A reorganization of MM 2 with no taxes. Go back to equation (*) in the
derivation, divide by SL + B

Exam review
What is the weighted average cost of capital?
Answer
Give the definitions and the formula. rB = bond rate
rS = expected return on shares
B = market value of bonds S = market value of shares TC = corporate tax rate
Conclusion
WACC =(S/(S+B))rS + (B/(S+B))(1-TC)rB
