Capital Structure

Definition

Capital structure is the specific mix of debt and equity that a company uses to finance its overall operations and growth. Equity comes from ownership shares in the company and claims on its future cash flows and profits.

Origin

The concept of capital structure dates back to the early 20th century, evolving with the increasing financing needs of modern enterprises. In 1958, Franco Modigliani and Merton Miller introduced the famous MM theory, marking a significant milestone in capital structure theory.

Categories and Features

Capital structure is primarily divided into two categories: debt financing and equity financing. Debt financing typically includes bank loans and bond issuance, characterized by the need for regular interest payments but without diluting shareholder equity. Equity financing involves raising funds through issuing stocks, which does not require regular interest payments but dilutes existing shareholders' ownership. Companies must balance interest costs, shareholder control, and financial risk when choosing their capital structure.

Case Studies

A typical example is Tesla, Inc. Throughout its development, Tesla has extensively used equity financing to support its rapid expansion and technological development. Through multiple stock issuances, Tesla successfully raised substantial funds, which, although diluting existing shareholders' stakes, provided significant growth potential for the company. Another example is Apple Inc., which prefers debt financing in its capital structure. By issuing bonds, Apple can raise funds at low interest rates and use its strong cash flow to pay interest, maintaining stable shareholder equity.

Common Issues

Investors often face challenges in evaluating a company's financial risk and determining the optimal debt-to-equity ratio when analyzing capital structure. A common misconception is that a high proportion of debt financing is always harmful; in reality, moderate debt can enhance shareholder returns through tax shields and leverage effects.
