Explanation

In credit ratings, different types of debt from the same issuer can have different ratings based on their seniority and security. The hierarchy is typically:

1. Senior Secured Debt - Highest priority, backed by specific collateral
2. Senior Unsecured Debt - Unsecured but has priority over subordinated debt
3. Subordinated Debt - Lowest priority, paid after senior debt

When a company has an issuer rating of B, this represents the company's overall creditworthiness. However, different debt instruments can be rated differently:

• Senior Secured Debt would typically be rated higher than the issuer rating (e.g., BB or BB-)
• Senior Unsecured Debt would typically be rated at or near the issuer rating (e.g., B or B+)
• Subordinated Debt would typically be rated lower than the issuer rating (e.g., B- or CCC+)

The question asks which type of debt is most likely to carry a rating of BB- when the issuer rating is B. Since BB- is higher than B, this would be senior secured debt, which typically gets upgraded ratings due to the collateral backing.

Correct Answer: B (Senior secured debt)

Reasoning:

• BB- is one notch higher than B (B → B+ → BB-)
• Senior secured debt typically receives higher ratings than the issuer rating due to collateral protection
• Subordinated debt would be rated lower than the issuer rating
• Senior unsecured debt would typically be rated at or near the issuer rating
