Fixed-Charge Coverage and Credit Ratings

Fixed-charge coverage and credit ratings evaluate debt capacity from complementary perspectives. The fixed-charge-coverage ratio compares a contractually or analytically defined resource with recurring fixed claims. Corporate credit ratings combine quantitative evidence with business risk, liquidity, financial policy, capital structure, support, and recovery judgment.

A company can pass a covenant while broader credit quality deteriorates. The test may use a permissive adjusted EBITDA definition, while refinancing risk, customer concentration, event risk, or market access weakens. The reverse also can occur: a company may breach a narrowly defined covenant even though it has cash, lender support, or another viable restructuring path.

Connect the Measures Carefully

Before relying on coverage or a rating:

• reconcile adjusted earnings, cash taxes, maintenance capital spending, rent, interest, principal, distributions, and add-backs;
• identify the legal entities, guarantors, collateral, debt priority, and restricted cash;
• distinguish issuer ratings from ratings on specific secured, unsecured, or subordinated obligations;
• review the agency, methodology, date, outlook, watch status, rationale, and rating triggers;
• calculate covenant and rating headroom under lower earnings, higher rates, and weaker refinancing conditions; and
• preserve a source trail to financial statements, agreements, forecasts, and agency publications.

Coverage ratios and ratings are analytical evidence, not guarantees of repayment, liquidity, price stability, or investment suitability. This section is educational and does not provide accounting, credit-rating, financing, legal, tax, or investment advice.
