CHAPTER 6: CAPITAL STRUCTURE Flashcards
COST OF CAPITAL
Cost of capital is the return expected by investors for providing capital to a company.
It ensures that investors earn a return greater than what they could get elsewhere.
Sources of Capital:
Companies can raise capital through equity, debt, or hybrid instruments.
Each source has a specific cost associated with it known as the component cost of capital.
Risk and Return:
Higher-risk investments demand a higher rate of return.
Lower-risk investments require a lower rate of return to attract investors.
Weighted Average Cost of Capital (WACC):
WACC is the weighted average of the costs of different sources of capital.
also called MARGINAL COST OF CAPITAL: because as the business grows, this cost changes: each additional unit of capital you raise, impacts the weights
WEIGHTS must represent the company’s TARGET CAPITAL STRUCTURE, not the current capital structure
It reflects the overall cost a company pays for financing its operations.
WACC is the appropriate discount rate to use for projects having similar risk profile as that of the firm
Common Sources of Capital:
Common shares (equity)
Preferred shares
Debt
WACC
required rate of return or discount rate
% of equity * Ke + % of debt * Kd * (1-T)
can break down ke into common & preferred equity=
% common * k of common
+
% preferred * k of preferred
Weighting in WACC
Weights represent the company’s target capital structure, not necessarily the current one.
Adjustments are made to reflect changes in capital structure when raising new funds.
Examples:
Example calculations involve determining WACC using given weights and costs of debt, preferred stock, and equity.
WACC helps in evaluating projects and making capital budgeting decisions.
CORPORATE LIFE CYCLE
Feature: Startup: Growth: Mature
Revenue Growth: Initial: Rising: Slowing
FCF: -ve: Rising: Stable
Business Risk: High: Medium: Low
Debt: None: Rising: High
Debt Type: Convertible: Secured: Unsecured
Start-Ups:
Revenues close to zero; heavy investment needed.
Negative cash flow; high risk of business failure.
Capital raised mainly through equity, often from venture capital.
Debt financing is scarce and expensive; rarely a part of capital structure.
Growth Businesses:
High revenue growth; ongoing investment required.
Cash flow may be negative but improving and predictable.
Risk of business failure decreases.
Equity remains the primary capital source; debt becomes available at reasonable terms as business attractiveness to lenders grows.
Debt used conservatively to maintain financial flexibility.
Mature Businesses:
Revenue growth slows; investment spending decreases.
Positive and predictable cash flow.
Low risk of business failure.
Debt financing available at attractive terms, often unsecured.
Companies leverage debt significantly to capitalize on cheaper financing compared to equity.
Deleveraging may occur over time through share buybacks rather than dividends, enhancing shareholder value.
Exceptions:
- Capital-Intensive Businesses:
Industries like real estate, utilities, and transportation.
High leverage throughout their lifecycle due to asset-backed collateral availability.
- Capital-Light Businesses:
Software and technology sectors.
Minimal debt usage; rely more on equity due to low capital requirements and early positive cash flows.
Determinants of the Costs of Debt and Equity
The costs of debt and equity are determined in the financial markets by top down factors that affect the overall market, as well as investor’s assessment of issuer specific factors.
- Top-Down Factors
Costs determined by market-wide conditions and investor-specific assessments.
Cost of Debt: Risk-free rate + credit spread specific to the company.
Market Conditions: Impact benchmark rates and credit spreads; widen in recessions, tighten in expansions.
Debt Usage: Increases with lower benchmark rates or tighter credit spreads.
Companies may increase their use of debt when borrowing is less expensive due to
low benchmark interest rates and/or tight credit spreads, and vice versa.
Issuer-Specific Factors:
- Sales Risk
- Profitability Risk
- Financial Leverage
- Collateral/Assets
Investor Assessment: Adjust rates of return based on:
- Sales Risk: Stable (e.g., telecom subscriptions) vs. volatile (e.g., cyclical industries like autos).
- Profitability Risk: Stable margins (fixed costs) vs. variable (operating leverage).
- Financial Leverage: High leverage increases default risk; underleveraged firms can take on more debt.
- Collateral/Assets: Strong assets (real estate, cash, receivables) support increased debt capacity.
Issuer-Specific Factors:
- SALES RISK
- Profitability Risk
- Financial Leverage
- Collateral/Assets
Stability of revenue streams based on business model.
Example: Telecom companies like Vodafone with subscription-based revenues are stable.
Impact: Viewed positively for financial stability.
Contrast: Cyclical industries like automotive (e.g., Toyota) have volatile revenues tied to economic cycles, viewed negatively.
Issuer-Specific Factors:
- Sales Risk
- PROFITABILITY RISK
- Financial Leverage
- Collateral/Assets
Stability of profit margins influenced by cost structure.
Key Factor: Proportion of fixed vs. variable costs determines profit margin stability.
Operating Leverage: Ratio of fixed costs to total costs.
Effect: Higher operating leverage amplifies changes in cash flow and profitability with revenue fluctuations.
Issuer-Specific Factors:
- Sales Risk
- Profitability Risk
- FINANCIAL LEVERAGE
- Collateral/Assets
Influence of existing debt levels on capital structure decisions.
Risk: Highly leveraged firms face higher default risk and reduced capacity for additional debt servicing.
Benefit: Underleveraged firms can more easily support additional debt, enhancing financial flexibility.
Issuer-Specific Factors:
- Sales Risk
- Profitability Risk
- Financial Leverage
- COLLATERAL/ASSETS
Assets that can secure debt or enhance borrowing capacity.
Examples: Real estate, automobiles, aircraft, and receivables from creditworthy customers.
Qualities: Strong collateral, cash-generating, fungible, or liquid assets.
Modigliani-Miller Capital Structure Propositions (VERY IMP)
Theory 1. 1958: No Taxes
Theory 2. Then updated in 1963: With Taxes
Theory 3. Static-Tradeoff Theory: With Taxes & Cost of Financial Distress
XY Axis:
Y: Cost of debt & equity
X: D/E ratio
Theory 1.
Proposition 1: VL=VU
Proposition 2: As you increase DEBT in capital structure= Kd remains same; Ke keeps going up as RISK increases. WACC is SAME/UNCHANGED.
Theory 2.
Proposition 1: VL= VU + tD
(why? because of tax benefit)
Proposition 2: As you increase DEBT in capital structure= Kd doesn’t change; Ke goes up. Debt is a tax-deductible expense. So, WACC goes DOWN.
Theory 3.
Proposition 1: VL=VU + tD - PV (cost of fin-distress)
Proposition 2: As you increase DEBT in capital structure= WACC goes DOWN. But, in financial distress, there is a cost associated with bankruptcy i.e. the cost of financial distress.
The PV of financial distress at some point becomes more than the tax benefit at sometime. So, WACC starts going up.
U shaped curve. WACC first comes down & then increases.
MIGLIANI-MILLER HAVE 2 PROPOSITIONS FOR EACH OF THE 3 THEORIES
Overview: Capital structure (mix of debt and equity financing) does not affect a company’s overall value under certain ideal conditions.
ASSUMPTIONS OF MODIGLIANI-MILLER CAPITAL STRUCTURE PROPOSITIONS
Assumptions:
- Homogeneous Expectations: All investors hold the same expectations regarding bond and stock cash flows.
- Perfect Capital Markets: No transaction costs, taxes, bankruptcy costs, and perfect information for all. No information asymmetry.
- Risk-Free Rate: Investors can borrow and lend at a risk-free rate.
- No Agency Costs: Managers always act in the best interest of shareholders.
- Independent Decisions: Financing and investment decisions are independent; operating income is unaffected by capital structure changes.
Capital Structure Irrelevance (MM Proposition I)
1958 THEORY
Statement: The market value of a company is independent of its capital structure.
Reasoning: Investors can replicate any desired capital structure through personal borrowing and lending, alongside holding company shares.
VL=VU
where,
VL= value of the levered firm
VU= value of the unlevered firm
why? because:
kE increases linearly (i.e. @45 degree angle); D/E on X axis.
kD remains same
WACC stays same
The size of the “pie” (total value of the company) remains constant regardless of how it’s divided between debt and equity.
These propositions form the basis for understanding how, under ideal conditions, a company’s value remains unchanged regardless of its debt-to-equity ratio.
In other words, the value of a company is determined solely by its cash flows, not
by the relative reliance on debt and equity capital.
MM Proposition I (Capital Structure Irrelevance)
(MM Proposition I without Taxes)
1963 Theory:
The value of a company (V) is unaffected by its capital structure.
V= E + D
where,
E= value of equity
D= value of debt
Weighted Average Cost of Capital (WACC):
The weighted average cost of capital (WACC) is unaffected by the capital structure.
% of equity * Ke + % of debt * Kd * (1-T)
The size of the “pie” (total value of the company) remains constant regardless of how it’s divided between debt and equity.
Figures show different capital structures (e.g., 70% equity, 30% debt vs. 70% debt, 30% equity) with the same total value of the company.
MM Proposition II (Higher Financial Leverage Raises the Cost of Equity)
WACC REMAINS CONSTANT
The cost of equity
rE= r0 + (r0-rd) D/E
increases linearly with the company’s debt-to-equity ratio (D/E).
where,
r0: cost of capital for a company with zero debt (equity-only financed).
rd: cost of debt.
𝐷/𝐸: D/E is the debt-to-equity ratio.
Impact: Increasing D/E ratio raises the perceived risk to equity investors, leading to a higher required return (cost of equity).
Relation to MM Proposition I: Despite changes in D/E ratio and subsequent adjustments in WACC (weighted average cost of capital), the overall value of the company remains unaffected (MM Proposition I).
WACC Determination: WACC is primarily determined by the business risk of the company, not its capital structure.
These points summarize MM Proposition II, which explains how increasing financial leverage (higher debt-to-equity ratio) affects the cost of equity while keeping the WACC constant.
Illustration: As leverage increases, the cost of equity rises, while WACC and the cost of debt remain constant.
MM Proposition I and II with Taxes
- MM Propositions I and II traditionally ignore taxes.
- With taxes considered, debt’s interest tax shield increases the company’s value if financial distress and bankruptcy costs are disregarded.
