• We are going to look at how changes in capital structure affect the value of the
firm, all else equal.
• The firm can increase leverage by issuing debt and repurchasing outstanding
shares.
• The firm can decrease leverage by issuing new shares and retiring outstanding
debt.
CHOOSING A CAPITAL STRUCTURE
• What is the primary goal of financial managers?
- Maximize stockholder wealth
• We want to choose the capital structure that will maximize stockholder wealth

MM Proposition I
The market value of a company is not affected by the capital structure of
the company.
• Based on the assumptions that there are no taxes, costs of financial distress,
or agency costs, so investors would value firms with the same cash flows as
the same, regardless of how the firms are financed.
• Reasoning: There is no benefit to borrowing at the firm level because there is
no interest deductibility. Firms would be indifferent to the source of capital and
investors could use financial leverage if they wish.
• It does not matter to the investor if the debt is held by the company or by the
investor herself. The latter case is termed homemade leverage.
• Bottom line: There is no benefit to using debt versus equity.
MM Proposition II:
The cost of equity is a linear function of the company’s debt/equity ratio.
• Because creditors have a claim to income and assets that has preference over
equity, the cost of debt will be less than the cost of equity.
• As the company uses more debt in its capital structure, the cost of equity increases
because of the seniority of debt:
𝐷𝐷
𝑟𝑟𝑒𝑒 = 𝑟𝑟0 + (𝑟𝑟0 −𝑟𝑟𝑑𝑑 )
𝐸𝐸
where r0 is the cost of equity if there is no debt financing.
• The WACC is constant because as more of the cheaper source of capital is used
(that is, debt), the cost of equity increases.
- In other words, the increase in the cost of equity is balanced out by the increased
use of the cheaper source of capital, debt.
• Bottom line: There is no benefit to using debt versus equity.
Bottom line: There is an optimal capital structure at which the value of the
firm is maximized and the cost of capital is minimized.
• Financial distress
Significant problems in meeting debt obligations
Firms that experience financial distress do not
necessarily file for bankruptcy.
THE STATIC THEORY OF CAPITAL STRUCTURE
• According to the static trade-off theory of capital structure, in choosing a capital
structure, a company balances the value of the tax benefit from deductibility of
interest with the present value of the costs of financial distress.
• At the optimal target capital structure, the incremental tax shield benefit is
exactly offset by the incremental costs of financial distress.
• A company may identify its target capital structure, but its capital structure at
any point in time may not be equal to its target for many reasons.
