Balance Sheet Strength and Capital Structure Review

Capital structure decisions determine whether a company survives a downturn or becomes a distressed-debt case study. Companies with debt-to-equity above 2.0x underperform low-leverage peers by 10.3% annually over long horizons, and those with interest coverage below 1.5x face bankruptcy rates 4.5x higher than adequately covered firms.¹ The practical antidote is a 5-ratio screen that separates sustainable leverage from fragile financing in about 20 minutes per company.

Debt-to-Equity and Debt-to-Capital (The Leverage Gauges)

The calculation: Debt-to-Equity = Total Debt / Total Shareholders' Equity

Use a 4-band classification that forces a decision:

• Conservative: <0.50x D/E (buffers for cyclical stress)
• Moderate: 0.50x-1.00x D/E (typical for stable cash flows)
• Elevated: 1.00x-2.00x D/E (acceptable only with strong coverage)
• High risk: >2.00x D/E (distress probability rises materially)

Why this matters: The 10.3% annual return gap between low-leverage and high-leverage firms persists across market cycles.¹ If D/E exceeds 2.0x, you need exceptional interest coverage or you pass.

The calculation: Debt-to-Capital = Total Debt / (Total Debt + Total Equity)

This ratio tells you what percentage of permanent capital comes from fixed-obligation sources. Below 30% is conservative; 30%-50% is balanced (common for industrials); 50%-65% is debt-heavy (typical for utilities); above 65% signals concentrated creditor risk.

The durable lesson: Debt-to-capital helps you compare across sectors. A utility at 55% debt-to-capital is standard; a retailer at the same level is at risk.

Interest Coverage Ratio (The Cash Flow Test)

The calculation: Interest Coverage = EBIT / Interest Expense

Interest coverage tells you how many times over a company can pay its interest bill from operating earnings. This is where leverage becomes dangerous or manageable.

The 4-tier framework:

• Strong: >6.0x (ample cushion through a recession)
• Adequate: 3.0x-6.0x (survives normal downturns)
• Marginal: 1.5x-3.0x (one bad year and covenants bind)
• Distressed: <1.5x (default probability elevated)

The practical point: A company at 2.0x coverage has roughly one bad year of earnings compression before fixed charges dominate. If coverage drops below 3.0x, you check debt covenants because the company may already be near technical breach territory.

Net Debt vs. Gross Debt (The Cash Offset)

The distinction:

• Gross debt: Total debt on the balance sheet
• Net debt: Total debt minus cash and cash equivalents

Why you use net debt: A company with $500M gross debt and $400M cash has fundamentally different risk than one with $500M gross debt and $50M cash. The first can retire 80% of its debt tomorrow; the second cannot.

The test: Net debt to EBITDA below 2.0x is conservative for most industrials; above 4.0x is elevated risk.

The point is: If a company shows high gross leverage but low net leverage, verify that cash is actually accessible (not trapped in foreign subsidiaries or restricted by working capital needs) before relaxing your concern.

Asset Quality (What Backs the Numbers)

You can have low leverage ratios and still face wipeout risk if assets are intangible, impaired, or illiquid.

Three asset quality checks:

1. Goodwill-to-Equity: If goodwill exceeds 50% of shareholders' equity, a write-down can destroy the equity cushion.

2. Intangibles-to-Total-Assets: When intangibles exceed 30% of total assets, the balance sheet contains limited tangible collateral.

3. Tangible Book Value: A company with $5B in equity and $4B in goodwill really has $1B of tangible equity. Your D/E ratio may understate true leverage by 5x.

The durable lesson: Acquisitive companies often carry hidden leverage in the form of goodwill that can evaporate in a single quarter.

Sector-Appropriate Leverage Levels

Leverage that kills a retailer is normal for a utility. Calibrate thresholds to sector economics:

Why this matters: Comparing a utility at 1.2x D/E to a tech company at the same level is meaningless. The utility has rate-regulated revenue; the tech company has customer acquisition risk.

Worked Example: Analyzing Acme Manufacturing Co.

Your situation: You are evaluating Acme Manufacturing (a hypothetical industrial company) for a potential investment.

Step 1: Compute leverage ratios

From Acme's balance sheet:

• Total Debt: $2.4B
• Shareholders' Equity: $3.2B
• Cash: $600M

You calculate:

• D/E = $2.4B / $3.2B = 0.75x (moderate band)
• Debt-to-Capital = $2.4B / $5.6B = 42.9% (within industrial norms)
• Net Debt = $1.8B

Step 2: Check interest coverage

• EBIT: $850M
• Interest Expense: $120M
• Interest Coverage = $850M / $120M = 7.08x (strong)

The point is: Acme can cover its interest bill 7 times over, leaving substantial cash flow for capex or debt paydown.

Step 3: Compute net debt to EBITDA

• EBITDA: $1.15B
• Net Debt to EBITDA = $1.8B / $1.15B = 1.57x (conservative)

Step 4: Check asset quality

• Goodwill: $1.1B
• Goodwill-to-Equity = $1.1B / $3.2B = 34.4% (below 50% warning line)
• Intangibles-to-Assets = $1.5B / $8.5B = 17.6% (below 30% caution zone)

The verdict: Acme passes all screens with margin. This is a strong capital structure for an industrial company.

Common Mistakes

Mistake 1: Using gross debt when net debt matters. You see $3B in debt but miss $2.5B in cash. Net debt is only $500M. Fix: compute both metrics.

Mistake 2: Ignoring off-balance-sheet obligations. You compute D/E as 0.8x but miss $2B in lease commitments. Adjusted leverage is 1.4x. Fix: add capitalized leases (use 7-8x annual lease expense as a multiplier) to your debt figure.

Mistake 3: Comparing leverage across sectors without adjustment. You avoid a utility at 1.1x D/E while buying a cyclical at 0.9x. The utility is actually safer. Fix: use sector-specific bands.

Next Steps

1. Pull the balance sheet for a company you own. Compute D/E and debt-to-capital. Does it fall in the conservative or elevated band for its sector?

2. Calculate interest coverage using EBIT and interest expense. Is coverage above 3.0x?

3. Check asset quality by computing goodwill-to-equity. Flag any company above 50% for deeper diligence.

4. Stress test coverage by assuming a 25% EBIT decline. Does coverage stay above 2.0x?
