## Financial Leverage: Trading on Equity and the Double-Edged Sword

### Financial Leverage as Trading on Equity

#### What is it?

Using fixed-cost funds (debentures, preference shares) alongside equity to finance the business, with the goal of boosting returns for equity shareholders.

#### The Mechanism

1. Company borrows money and pays a fixed cost (interest).

2. Business operations generate returns.

3. If returns > fixed cost → Surplus belongs entirely to equity shareholders.

4. This surplus is not diluted across debt holders — only equity holders benefit.

#### When Is It Good (Positive / Favourable Leverage)?

Condition: Earnings on investment > Cost of debt
Effect: EPS increases; equity shareholders earn more than they would without leverage.
Called: Favourable Financial Leverage

#### When Is It Bad (Negative / Unfavourable Leverage)?

Condition: Earnings on investment ≤ Cost of debt
Effect: Equity shareholders bear the fixed cost burden; EPS falls or turns negative.
Called: Unfavourable Financial Leverage

### Financial Leverage as a Double-Edged Sword

Financial leverage amplifies outcomes in both directions — it does not just help, it also hurts.

ROI vs Interest	Effect	Verdict
ROI > Interest	EPS ↑, ROE ↑	Advantageous — use leverage
ROI < Interest	EPS ↓, ROE ↓, financial distress	Disadvantageous — leverage harms
ROI = Interest	No change in EPS	Neutral — leverage has no effect

### Why 'Double-Edged'?

The same fixed commitment that supercharges EPS in good times destroys EPS in bad times.
In a downturn, revenue falls but interest must still be paid → EPS collapses faster than EBIT.
This is why high leverage firms are more volatile and perceived as riskier.

### The Key Rule on DFL

> Degree of Financial Leverage (DFL) can NEVER be between 0 and 1.

> - If DFL = 0 or negative → EBIT is at or below the financial break-even point.

> - If DFL ≥ 1 → Normal operating range above break-even.

> - Values between 0 and 1 are mathematically impossible given the DFL formula.

Worked example

### Example 1

Double-Edged Sword — Both Scenarios:

Capital: ₹10 lakh equity (1,000 shares) + ₹10 lakh @ 10% debt. Tax = 40%.

Interest = ₹1 lakh per year.

Scenario A — Good year (ROI = 20%):

EBIT = ₹20 lakh × 10% × 2 = ₹4 lakh
Actually EBIT = ROI × Total Assets = 20% × ₹20 lakh = ₹4 lakh
EBT = ₹4 − ₹1 = ₹3 lakh; Tax = ₹1.2 lakh; EAT = ₹1.8 lakh
EPS = ₹1.8 lakh ÷ 1,000 = ₹180

Without debt (2,000 shares, all equity):

EAT = ₹4 lakh × 60% = ₹2.4 lakh; EPS = ₹2.4 lakh ÷ 2,000 = ₹120

→ Leverage boosted EPS from ₹120 to ₹180.

Scenario B — Bad year (ROI = 4%):

EBIT = 4% × ₹20 lakh = ₹0.8 lakh
EBT = ₹0.8 − ₹1 = −₹0.2 lakh (loss)
EPS is negative

Without debt:

EAT = ₹0.8 lakh × 60% = ₹0.48 lakh; EPS = ₹24 (still positive)

→ Leverage turned a positive EPS into a negative EPS. The sword cut the wrong way.

⚠️ Common exam mistakes

Thinking DFL between 0 and 1 is possible — it is not. This is a frequently tested conceptual point in MCQs.
Saying financial leverage is always good — it is only good when ROI > cost of debt. When ROI falls, leverage amplifies losses.
Confusing the 'neutral' case (ROI = interest) with 'no leverage' — in the neutral case, leverage still exists (DFL > 1), but the ROI happens to exactly equal the interest rate, so neither gain nor loss accrues.
Forgetting that preference dividend, unlike interest, is not tax-deductible — this makes preference capital more expensive than debt on an after-tax basis, even if the stated rate is the same.
