This lesson examines the practical factors that influence how financial managers design a firm’s capital structure. It covers both the theoretical drivers identified in the literature and the practical considerations managers weigh in their decision-making.

• Taxation: Corporate taxation is a key determinant because interest on debt is tax-deductible, while dividends on equity are not. Higher corporate tax rates make debt financing more attractive due to the tax shield benefit.

• Risk and Financial Distress: The risk of cash insolvency and the risk of variation in earnings are critical factors. Higher debt increases financial risk as fixed interest charges must be met regardless of profitability. The potential for financial distress and bankruptcy costs creates a limit on the use of debt. Firms with stable and certain earnings can support higher debt levels.

• Profitability and Growth: The pecking order theory is supported by the significant negative correlation between profitability and leverage—more profitable firms tend to borrow less. Growth opportunities can also affect leverage, with firms having high growth potential often preferring equity to avoid financial distress costs.

• Agency Conflicts and Managerial Incentives: Agency problems between shareholders and managers influence capital structure. Issues such as debt overhang (where existing debt discourages new investment) and risk-shifting (where shareholders take excessive risks) are critical considerations.

• Flexibility and Control: Financial flexibility—the ability to raise funds as and when required—is a major concern for CFOs. Control is also important; if existing shareholders do not wish to dilute control, they may prefer debt capital, which has no voting rights.

• Industry and Size: Smaller firms find it more difficult to raise debt capital on favourable terms and thus depend more on equity and retained earnings. Larger firms can issue various securities and often have easier access to debt markets.
