Overview and Cost of Capital5 min
This chapter introduces capital structure—the long-term mix of debt and equity financing that supports a firm's assets and operations—and its relationship to the firm's weighted-average cost of capital (WACC). The component costs are investors' required returns: cost of debt (rd), typically observed from market yields or recent borrowings and adjusted for taxes, and cost of equity (re), which is higher because equity is riskier. WACC blends these costs by market or target weights and is the hurdle rate for investment appraisal. Top-down factors (macro conditions, credit markets, industry cycles) and issuer-specific factors (cash-flow stability, operating leverage, asset tangibility, interest coverage) jointly determine the costs of debt and equity and therefore influence feasible capital structures. Business model and life-cycle stage determine financing needs: startups favor equity and convertible instruments, growth firms use limited secured debt, and mature firms can support unsecured debt.

Key Points

  • Capital structure is the long-term mix of debt and equity.
  • WACC is the weighted blend of after-tax cost of debt and cost of equity.
  • Cost of equity exceeds cost of debt because equity bears more risk.
  • Business model and life cycle shape financing needs and feasible debt levels.
Modigliani–Miller and Taxes5 min
MM Proposition I (no taxes) states firm value equals the present value of expected cash flows and is independent of capital structure; equity cost rises linearly with leverage (MM Proposition II) so WACC stays constant. Introducing corporate taxes makes debt attractive because interest is tax-deductible: VL = VU + tD, which lowers WACC as leverage increases. However, additional leverage raises the probability and expected costs of financial distress (direct legal/administrative costs and indirect costs like lost customers or suppliers), which offset tax benefits. The static trade-off theory posits an optimal leverage level where marginal tax shield benefits equal marginal expected distress costs. The chapter shows algebraic forms of MM propositions and examples illustrating the changes in cost of equity, WACC, and firm value when debt is introduced with and without taxes.

Key Points

  • MM without taxes: capital structure irrelevant to firm value.
  • MM Proposition II: higher leverage raises cost of equity, offsetting cheaper debt.
  • With corporate taxes, debt creates a tax shield: VL = VU + tD.
  • Financial distress costs create a trade-off against tax benefits.
Practical Theories and Corporate Policy5 min
Pecking-order theory arises from asymmetric information and signaling: firms prefer internal financing, then debt, then equity; this yields no single optimal capital structure but explains issuance patterns. Agency considerations such as the free cash flow hypothesis argue debt disciplines managers by committing cash to fixed obligations. Firms use target capital structures, often expressed with book values for operational and rating purposes, and maintain target ranges. Analysts estimate WACC using market or target weights, adjust for hybrids, and consider leasing and secured debt as debt-like financing. Industry regulation, asset tangibility, and collateral markets affect distress costs and therefore optimal leverage. Managers cannot precisely compute the exact optimal debt level, so they set practical policies and ranges and periodically rebalance. Practical tools include using market-value weights for WACC, incorporating tax rates, and modeling expected distress costs when estimating value-maximizing leverage.

Key Points

  • Pecking-order theory: internal funds, then debt, then equity.
  • Agency costs and the disciplining role of debt are important considerations.
  • Target capital structures are implemented as ranges; book values often used for policy.
  • Analysts must account for taxes, distress costs, and hybrid instruments in estimating WACC.
