Capital Structure I:
Basic Concepts
The Capital-Structure Questionand The Pie Theory
The value of a firm is defined to be the sum of the value of the firm’s debt and the firm’s equity.
V = B + SIf the goal of the management of the firm is to make the firm as valuable as possible, the the firm should pick the debt-equity ratio that makes the pie as big as possible.

The Capital-Structure Question
There are really two important questions:1. Why should the stockholders care about
maximizing firm value? Perhaps they should be interested in strategies that maximize shareholder value.
2. What is the ratio of debt-to-equity that maximizes the shareholder’s value?
As it turns out, changes in capital structure benefit the stockholders if and only if the value of the firm increases.

Consider an all-equity firm that is considering going into debt. (Maybe some of the original shareholders want to cash out.)

Homemade Leverage: An Example
Recession Expected ExpansionEPS of Unlevered Firm $2.50 $5.00 $7.50
Earnings for 40 shares $100 $200 $300Less interest on $800 (8%) $64 $64 $64Net Profits $36 $136 $236ROE (Net Profits / $1,200) 3% 11% 20%
We are buying 40 shares of a $50 stock on margin. (40% of funds borrowed) We get the same ROE as if we bought into a levered firm.Our personal debt equity ratio is:
32
200,1$

Homemade (Un)Leverage:An Example
Recession Expected ExpansionEPS of Levered Firm $1.50 $5.67 $9.83
Earnings for 24 shares $36 $136 $236Plus interest on $800 (8%) $64 $64 $64Net Profits $100 $200 $300ROE (Net Profits / $2,000) 5% 10% 15%
Buying 24 shares of an other-wise identical levered firm along with the some of the firm’s debt gets us to the ROE of the unlevered firm.This is the fundamental insight of M&M
The MM Proposition I: Capital Structure and Firm Value
Assuming a un-levered firm, and funds from equity. The after-tax profit is The operation cash flows is To maintain same asset size, the firm needs to invest, same as
Dep., on capital. So the firm’s free cash flows becomes
The value of this un-levered firm, assuming perpetuity, is defined as
ksu is the cost of capital (equity) for a un-levered firm.

For a levered firm, funds from both equity and debt. The total cash flow for firm can be divided by that goes to
Debt holders: where D is the value of debt, and kD is risk-free rate
Stockholders:
So the total cash flows to firm becomes
EBIT(1-t) is the same as that of un-levered firm, and tkD is a risk-free cash flow. So the value of firm is

One firm now has 20% debt and 80% equity. The CFO believes it can increase leverage to 40% debt financing without raising its 7% cost of debt. Assuming that and marginal tax rate is 25%

If the firm faces a project (same risk as the firm) with a return of 9.5%, should the firm accept the project?
No it should not. The project return 9.5% is lower than that of WACC 9.94%。
