Capital Structure & Financial Leverage Cheat Sheet

Explore how a firm's mix of debt and equity (capital structure) impacts its value, cost of capital, and shareholder returns, considering various theories from perfect markets to real-world complexities.

Core Principles

Capital structure is the mix of debt and equity used to finance a firm's assets.
The guiding principle for capital structure decisions is to maximize shareholders' wealth.
Financial leverage amplifies both gains and losses for shareholders.
The Modigliani-Miller (M&M) theorems provide foundational insights into capital structure irrelevance and the impact of taxes.
The Static Trade-off Theory suggests an optimal capital structure balances tax benefits against financial distress costs.

Action Steps

Understand the basic definition of capital structure and its components (debt and equity).
Recognize that the ultimate goal of capital structure decisions is to maximize firm value.
Analyze how financial leverage magnifies returns (EPS, ROE) but also increases risk.
Study the M&M propositions to grasp theoretical impacts of capital structure under different assumptions (no taxes, with taxes).
Consider the Static Trade-off Theory to understand the real-world balance between tax shields and financial distress costs.

Formulas

$V = E + D$
$WACC = \frac{E}{V} R_E + \frac{D}{V} R_D (1-T_c)$
$R_E = R_A + (R_A - R_D) \times \frac{D}{E}$
$V_L = V_U + D \times T_c$
$V_L = V_U + D \times T_c - PV(\text{Cost of Financial Distress})$

Key Terms

Capital Structure: The specific mix of debt and equity a company uses to finance its operations and assets.
Financial Leverage: The extent to which a firm relies on debt financing; amplifies returns and risks.
WACC: Weighted Average Cost of Capital; the average rate a company expects to pay to finance its assets.
Modigliani-Miller Theorems: Theories proposing capital structure irrelevance (no taxes) and value maximization with debt (with taxes).
Interest Tax Shield: The reduction in taxes a firm achieves due to the tax deductibility of interest payments on debt.
Financial Distress Costs: Costs incurred when a firm faces bankruptcy or severe financial difficulty, including direct (legal) and indirect (lost business) costs.

Pro Tips

In the absence of taxes and bankruptcy costs, capital structure is irrelevant (M&M Proposition I).
With taxes, debt financing offers a tax shield, increasing firm value (M&M Proposition I with taxes).
The optimal capital structure balances the tax benefits of debt against the costs of financial distress.
Shareholders are exposed to higher risk with increased financial leverage.
The 'break-even point' in EPS/EBIT analysis shows where leverage becomes advantageous.

Pitfalls to Avoid

Assuming capital structure is always irrelevant without considering taxes or distress costs.
Ignoring the increased financial risk associated with higher debt levels.
Overlooking the potential costs of financial distress and bankruptcy.
Applying M&M theorems without accounting for their underlying assumptions.
Failing to recognize that the 'optimal' structure is a trade-off, not a single point.

Real World Examples

Trans Am Corporation restructuring: Demonstrates how issuing debt and repurchasing equity increases financial leverage, amplifying EPS and ROE but also risk.
BF Ltd debt financing: Illustrates M&M Propositions I & II, showing how cost of equity increases with leverage, but WACC can remain constant (Case I) or decrease (Case II) due to tax shields.
Ricardo Corporation's cost of equity: Applies M&M Proposition II to calculate the cost of equity and WACC at different debt-equity ratios, confirming WACC remains constant without taxes.
