Notching in Credit Ratings

Rating notching is the practice of assigning a rating above or below a reference rating to reflect differences in priority, recovery, support, legal structure, or other credit characteristics. It commonly explains why obligations of the same corporate group do not all carry the issuer’s headline rating.

Key Takeaways

• A notch is one step on the assigning agency’s relevant rating scale.
• Notching can apply to debt issues, subsidiaries, holding companies, preferred securities, or other obligations.
• Seniority, collateral, guarantees, structural subordination, loss absorption, and recovery can affect direction and magnitude.
• Secured debt is not automatically notched up, and subordinated debt is not assigned a universal number of downward notches.
• Agency methodologies, sectors, jurisdictions, and rating levels differ.
• Notching is a credit-rating relationship, not a fixed pricing spread or recovery percentage.

Reference Rating and Notched Rating

The reference point may be an issuer credit rating, issuer default rating, stand-alone credit profile, group credit profile, or another agency-defined anchor. The notched result applies to a specific entity or obligation.

Worked Example: Parent and Subsidiary Debt

Assume a corporate group has an operating subsidiary that owns most assets and generates most cash flow. The subsidiary has secured bank debt, while the parent holding company has unsecured notes with no subsidiary guarantee.

In distress:

1. subsidiary creditors claim operating assets and cash flow first;
2. value reaches the parent only after subsidiary obligations are satisfied; and
3. parent noteholders may therefore face structural subordination.

An agency may notch the parent notes below a reference issuer or group rating. If the operating subsidiaries provide strong guarantees or debt is reorganized, the gap may change. The example does not prescribe a particular number of notches.

Issue Notching and Recovery

Issue notching often connects default risk with expected loss severity. Two obligations can depend on the same issuer but have different recovery prospects because one is secured and senior while the other is unsecured or subordinated.

Some methodologies use separate recovery ratings; others incorporate recovery or priority directly into issue ratings. Read both the rating definitions and the sector methodology before interpreting the result.

Other Forms of Notching

Parent-subsidiary relationships

Ratings can differ because cash, assets, regulation, minority owners, or legal barriers limit support between entities.

Government or group support

An entity may receive uplift from an expected support provider, or its rating may be constrained by a weaker parent or operating environment under agency criteria.

Hybrid and preferred instruments

Deferral, subordination, permanence, write-down, conversion, and loss-absorption features can lead to downward notching from a senior or issuer reference point.

Structured finance

Tranches receive different ratings based on cash-flow priority, credit enhancement, collateral performance, and legal structure. This is broader tranche analysis and should not be reduced to corporate seniority rules.

How to Analyze Notching

1. Identify the agency, methodology, reference rating, and rated obligation.
2. Count notches using that agency’s actual scale and modifiers.
3. Map legal issuers, guarantors, collateral, liens, and structural subordination.
4. Review enterprise value, priority waterfall, recovery assumptions, and jurisdiction.
5. Identify support, deferral, write-down, conversion, and loss-absorption features.
6. Check whether the notching is capped, widened, or compressed at certain rating levels under the methodology.
7. Compare with independent recovery and covenant analysis.
8. Update after refinancing, guarantee release, collateral changes, or capital restructuring.

Common Mistakes and Limitations

• Assuming every secured issue is one notch above the issuer rating.
• Applying one agency’s notching rules to another agency’s scale.
• Ignoring structural subordination between parent and subsidiaries.
• Treating a notch as a fixed spread or loss percentage.
• Comparing issue ratings without identifying the reference rating.
• Assuming guarantees and collateral have full practical value without legal review.
• Ignoring debt issued after the rating date.

Notching is methodology- and structure-specific. This article is educational and is not a credit rating, legal priority opinion, recovery estimate, tax conclusion, lending decision, or investment recommendation.
