How to decide the optional capital structure?

What’s the objective?maximize firm valuemaximize firm valueminimize WACC

A particular debt/equity ratio represents the optional capital structure if it results in the lowest possible WACC.

Financial Leverage 財務槓桿／ Financial Risk 財務風險

Financial leverage affects the payoffs to stockholders.

An example:Panel A: Current capital structure: no debtRecession Expected ExpansionEBIT 500000 1000000 1500000interest 0 0 0net income 500000 1000000 1500000ROE 6.25% 12.50% 18.75%EPS 1.25 2.5 3.75

Panel B: Proposed capital structure: debt = 4 million

Conclusion

The effect of financial leverage depends on the firm’s EBIT. When EBIT is relatively high, leverage is beneficial.Shareholders are exposed to more risk under the proposed capital structure since the EPS and ROE are much more sensitive to change in EBIT.

9

Question

Because of the impact that financial leverage has on both the expected return to stockholders and the riskness of the stock, capital structure is an important consideration.Answer: no.∵Shareholders can adjust the amount of financial leverage by borrowing and lending on their own. The use of personal borrowing to alter the degree of financial leverage is called homemade leverage.

Homemade leverage

Panel A: proposed capital structure

Recession Expected ExpansionEPS 0.5 3 5.5Earnings for 100 shares 50 300 550Net cost 100*20=2000

11

Panel B: original capital structure and homemade leverage

Recession Expected ExpansionEPS 1.25 2.5 3.75Earnings for 200 shares 250 500 750Less: interest on 2000 at 10% 200 200 200Net earnings 50 300 550Net cost 200*20-amount borrowed=4000-2000=2000

12

Investors can always increase financial leverage themselves to create a different pattern of payoffs. It thus makes no different whether a firm restructure the capital structure.There is nothing special about corporate borrowing because investors can borrow or lend on their own. As a result, whichever capital structure a firm chooses, the stock price will be the same.

M&M proposition I: Modigliani and Miller

The value of the firm is independent of its capital structure.Example:

• .firm value distribution: stockholders vs. debtholders.

• .whole milk: cream vs. skim milk.• .pie: more pieces, but not more pizza. The siz

e of the pizza does not depend on how it is sliced.

14

M&M proposition II

A firm’s cost of equity is a positive linear function of its capital structure.

Without debt, the WACC is 10%, and, with debt, the WACC is 9.6%. The firm is better off with debt.
