Issue vs Issuer Ratings

Rating agencies publish two types of ratings: the issuer rating, which summarizes the company's overall creditworthiness, and issue-specific ratings for individual bonds or tranches. A company rated A overall might issue senior secured bonds rated AA (lower default risk due to seniority and collateral) and subordinated bonds rated BBB or BB (higher default risk because subordinated creditors absorb losses first). Understanding this hierarchy explains bond price differences and recovery prospects in distress.

Key takeaways

• The issuer rating reflects the company's overall ability to meet all financial obligations; it is often an unweighted average of the company's debt profile.
• Issue ratings account for the specific bond's seniority level (senior vs. subordinated) and security (secured vs. unsecured) and therefore often differ materially from the issuer rating.
• A senior secured bond is typically rated 1–3 notches higher than the issuer rating because collateral and priority reduce loss-given-default.
• A subordinated or junior bond is typically rated 1–3 notches lower than the issuer rating because subordinated creditors absorb losses after senior creditors.
• In bankruptcy, the waterfall of recovery favors senior secured → senior unsecured → subordinated → equity. This legal priority is reflected in issue ratings.

The issuer rating: the company as a whole

The issuer rating is a rating of the company or government entity's overall creditworthiness. For example, Johnson & Johnson has an issuer rating of AAA; General Motors has an issuer rating of B−/Ba3; Ford Motor has BB/Ba1.

The issuer rating synthesizes the company's:

• Total debt load and leverage.
• Operating earnings stability.
• Market position and competitive moat.
• Management and financial policy.
• Industry dynamics and cyclicality.

It is not tied to a specific bond maturity or obligation. Rather, it reflects the agency's assessment of the company's ability to meet all financial commitments (short-term and long-term, principal and interest).

Many investors use the issuer rating as a shorthand for the company's credit quality. A portfolio statement might say "85% of our credits are A-rated or higher" to indicate broad credit quality, referring implicitly to issuer ratings.

Issue ratings: the specific bond

Each bond or debt instrument issued by a company receives its own rating. A large corporation might have 20–50 individual bonds outstanding, each with its own issue rating.

The issue rating reflects:

• Seniority: Is the bond senior or subordinated in the payment waterfall?
• Security: Is the bond secured (backed by specific collateral) or unsecured?
• Maturity: Longer-dated bonds sometimes carry higher default probabilities than shorter-dated bonds from the same issuer.
• Covenants: Bonds with tight covenants (restrictions on asset sales, dividend payments, new debt) may receive higher ratings.

Because of these factors, issue ratings can diverge substantially from the issuer rating.

Seniority and the recovery waterfall

When a company enters bankruptcy, creditors are paid according to a legal waterfall:

1. Secured senior debt (backed by collateral, first lien): Recovers from collateral proceeds; if collateral is worth 70% of the loan, the bondholder recovers 70%.
2. Senior unsecured debt: Recovers from remaining company assets; typically recovers 30–60% depending on asset availability.
3. Subordinated debt: Recovers only after senior debt is satisfied; typically recovers 10–40%, sometimes nothing.
4. Preferred shares: Recover after debt, before equity; typically recover 5–20%.
5. Common equity: Recovers last, often nothing.

Rating agencies assign issue ratings using a "recovery rate" assumption. A bond expected to recover 70% in default scenarios receives a higher rating than a bond expected to recover only 20%, even if both are from the same issuer.

Example: three bonds from the same company

Consider a mid-size industrial company rated BBB on an issuer basis. The company issues three tranches of debt:

1. Senior secured bond (backed by plant and equipment): Rated BBB+ or A− (1–2 notches higher than issuer) because collateral secures it and it has first claim on assets.

2. Senior unsecured bond (same seniority to other senior unsecured debt): Rated BBB (same as issuer rating) because it receives standard treatment in bankruptcy.

3. Subordinated note (junior to all senior debt): Rated BB or BB+ (1–2 notches lower than issuer) because subordinated creditors absorb losses after senior creditors.

The yield premiums typically track the ratings:

• Senior secured: 100–150 bps over Treasuries.
• Senior unsecured: 120–200 bps.
• Subordinated: 200–300 bps.

An investor accepting subordinated status earns extra yield, but shoulders higher loss probability.

Security and collateral

Secured bonds are backed by specific collateral (real estate, equipment, receivables, inventory). In bankruptcy, the bondholder has a claim on the collateral before other creditors.

Types of secured bonds:

• Mortgage bonds: Backed by real property; typically senior. Often issued by utilities, railroads, or REITs.
• Equipment bonds: Backed by machinery, vehicles, or other tangible assets. Common in transportation and leasing.
• Collateral trust bonds: Backed by securities (stocks, bonds, other financial assets) held in trust.

Secured bonds typically receive issue ratings 1–3 notches higher than senior unsecured from the same issuer, reflecting the collateral support.

Example: Utility Company X has an issuer rating of A. Its mortgage bond (secured by utility plant) might be rated AA− or AA. Its unsecured debt is rated A. A subordinated note might be rated BBB+ or A−.

Covenants and issue rating nuances

Bonds with tight covenants—restrictions on the company's actions—sometimes receive higher issue ratings because the covenants limit the company's ability to weaken its balance sheet.

Examples of restrictive covenants:

• Debt-to-EBITDA limit: Issuer cannot let leverage exceed 4x; breached, the bond becomes immediately due (acceleration).
• Interest coverage limit: EBITDA must remain above 3x interest expense.
• Dividend restriction: Issuer cannot pay dividends if leverage exceeds 3x.
• Asset sale restriction: Issuer cannot sell major assets without bondholder consent.

A bond with a debt-to-EBITDA covenant capped at 3x may receive a higher rating than a bond with a looser 5x cap, even if both are senior unsecured, because the covenant constrains the issuer's financial flexibility.

Maturity and issue ratings

In rare cases, longer-maturity bonds from the same issuer receive lower issue ratings than shorter-maturity bonds if the company's prospects are uncertain over extended horizons.

Example: A startup tech company rated B might issue a 3-year note at B and a 10-year bond at B− because the 10-year horizon introduces greater uncertainty. More commonly, maturity has little impact on issue ratings if the issuer's fundamentals are stable.

Bank loans and first-lien structures

Many companies borrow via bank loans (often syndicated) that are senior secured and have strict covenants. These loans typically receive issue ratings 1–2 notches higher than senior unsecured bonds, sometimes even higher than the issuer rating if the collateral is substantial and covenant packages are tight.

A company rated BBB overall might have:

• Term loan A (senior secured, strict covenants): Rated BBB+ or A−.
• Bond (senior unsecured): Rated BBB.
• Subordinated notes: Rated BB or BB+.

Professional investors (banks, CLO managers, distressed specialists) pay close attention to covenant packages because they affect not just the issue rating but also the probability of workout scenarios and recovery rates.

Hybrid securities: the gray zone

Some securities blur the line between debt and equity. Examples:

• Convertible bonds: Bonds that can be converted into equity. They are debt senior to equity but subordinate to straight debt. Ratings: typically 1–2 notches lower than straight debt from the same issuer.
• Perpetual notes: Debt that never matures (unless the company calls it). From a rating perspective, these are treated as more equity-like. Ratings: typically 2–3 notches lower than senior unsecured.
• Preferred shares: Equity instruments with debt-like dividend commitments. Not rated by agencies (though credit analysts often apply implicit ratings). In bankruptcy, recover after all debt but before common equity.

These hybrids are rated lower because they have subordinated status or equity-like characteristics.

Practical implications for investors

1. If you are seeking stability, prioritize senior secured or senior unsecured bonds from A-rated or higher issuers. Issue ratings should match or slightly exceed the issuer rating.

2. If you are seeking yield, consider subordinated bonds from stable issuers. A subordinated note from an A-rated issuer might yield 200 bps more than a senior unsecured bond, for an acceptable risk trade-off.

3. In distressed scenarios, issue rating matters enormously. A senior secured bond at 50 cents on the dollar might recover to par; a subordinated bond at 20 cents might recover only to 15 cents.

4. Monitor covenant packages. A bond with tight covenants may recover better in distress because the covenants restrict deterioration. A bond with loose covenants gives the issuer more room to weaken its balance sheet.
