Definition / Meaning of Pecking order theory

The pecking order theory is a corporate finance concept that explains how companies prioritize their sources of financing. It suggests that firms have a distinct preference for using internal funds first, then debt, and finally equity as a last resort. This theory was first articulated by economist Gordon Donaldson in the 1960s, and later refined by Stewart Myers and Nicolas Majluf in the 1980s.

The central idea is that because of information asymmetry (where managers know more about the company’s value than outside investors), firms will follow a specific hierarchy when raising capital. The theory assumes that managers act in the best interests of existing shareholders and want to avoid sending negative signals to the market.

The Financing Hierarchy

Companies following the pecking order theory will use these sources in a specific order:

1. Internal Financing (Retained Earnings): The first and most preferred source. This includes using the company’s own profits, cash reserves, and retained earnings. Internal financing has no transaction costs, no dilution of ownership, and does not require disclosing sensitive information to outsiders.
2. Debt Financing: If internal funds are insufficient, the company will turn to borrowing. This can include bank loans, issuing corporate bonds, or other forms of debt. Debt is preferred over equity because it is less sensitive to information asymmetry and interest payments are tax-deductible.
3. Equity Financing: The last resort. Issuing new shares of common stock is seen as a signal that the stock might be overvalued. Companies will only use equity when they have exhausted internal funds and debt capacity are no longer available.

Why Does This Order Exist?

The pecking order is driven by several key factors:

• Information Asymmetry: Managers have more information about the company’s true financial health and future prospects than outside investors. When a company issues new equity, investors may interpret it as a sign that the stock is overvalued, causing the share price to drop.
• Cost of Financing: Internal funds are the cheapest because there are no underwriting fees, legal costs, or disclosure requirements. Debt is next cheapest, followed by equity which carries high issuance costs and potential dilution.
• Signaling Effects: Using internal funds sends a positive signal that the company is profitable. Using debt signals confidence that the company can service the debt. Issuing equity signals desperation or overvaluation.

Practical Implications

In practice, many companies follow the pecking order theory. For example, a profitable company like Apple often uses its massive cash reserves for investments and acquisitions instead of borrowing or issuing shares. A growing startup that has no retained earnings would use venture debt or bank loans before issuing new equity to the public.

This theory also explains why many firms do not have an optimal capital structure target. Instead, they adjust their debt levels based on their need for external financing. A company with strong internal cash flow will have low debt, while one with large investment needs will have higher debt.

Criticisms and Limitations

While influential, the pecking order theory has its critics. Some companies regularly issue equity without experiencing a drop in share price, especially if they have good growth prospects. The theory also does not account for the trade-off theory, which suggests that firms balance the tax benefits of debt against the costs of financial distress.

Additionally, the theory assumes managers are always rational and markets are efficient, which is not always true in the real world. Companies may violate the pecking order due to regulatory requirements, market timing, or strategic reasons unrelated to information asymmetry.

Conclusion

The pecking order theory remains one of the most widely taught and studied concepts in corporate finance. It provides a logical framework for understanding why companies choose certain financing methods over others. By recognizing the hierarchy of preferences, investors and analysts can better interpret a firm’s financial decisions and the signals they send to the market.
