The New Principle-Based Bond Definition (SSAP No. 26 & 43)#

Under US Statutory Accounting Principles (SAP) governed by the NAIC, classifying an investment as a "Bond" allows for favorable capital treatment. Historically, insurers classified highly complex, risky equity-like structures as "bonds." To stop this, the NAIC implemented The Principle-Based Bond Project.

The Two Distinct Categories#

A security must pass a strict principle-based test to qualify for Schedule D-1 reporting:

1. Issuer Credit Obligations (SSAP No. 26R)#

The repayment must rely entirely on the general creditworthiness of the operating entity. Does the issuer have operations and cash flows separate from the specific assets backing the bond? If yes, it’s an Issuer Credit Obligation.

2. Asset-Backed Securities (ABS) (SSAP No. 43R)#

Repayment relies entirely on the cash flows generated by a specific pool of underlying assets. To qualify, an ABS must have a "substantive credit enhancement" (like overcollateralization) ensuring the bondholder gets paid even if underlying assets suffer losses.

If a security fails, it must be reported as standard equity, subjecting the insurance company to massive, punitive risk-based capital (RBC) charges.

Why the Definition Matters#

Classification drives where a holding is reported, how it is measured and what capital charge it attracts. That is why the label "bond" carries so much weight. A holding that sits in Schedule D-1 as a bond receives the treatment the article describes above; one that fails is pushed into a different category with a very different capital outcome. For a finance team, the practical question is therefore not "what did we call it when we bought it?" but "does it pass the principle-based test on its own terms?"

Decision Approach: A Practical Walk-Through#

The following is a simplified way to think through a holding. It is a working aid, not a substitute for the text of the statements.

  1. Start with the source of repayment. Ask what the holder is relying on to be paid back.
  2. If repayment relies on the general creditworthiness of an operating entity that has its own operations and cash flows separate from any specific assets, the holding points toward an issuer credit obligation (SSAP No. 26R).
  3. If repayment relies entirely on cash flows from a specific pool of assets, the holding points toward an asset-backed security (SSAP No. 43R).
  4. For an ABS, test the credit enhancement. Look for a substantive credit enhancement, such as overcollateralization, that supports payment to the bondholder even if the underlying assets suffer losses.
  5. If the holding fits neither category, it is not reported as a bond and, as noted above, faces the harsher capital treatment.

Worked Example (Illustrative Only)#

The numbers are round figures to show the logic, not real transactions.

  • Holding A: A note issued by a company that runs an operating business. Repayment depends on that company's general ability to pay from its overall operations. The analysis points to an issuer credit obligation.
  • Holding B: A security whose repayment comes only from the cash flows of a pool of receivables worth 100 (illustrative), with notes issued totalling 90 (illustrative). The 10 excess of collateral over notes is a form of overcollateralization. Whether it is "substantive" is a judgement that depends on the specifics of the structure, so the question must be assessed, not assumed.
  • Holding C: A structure where repayment depends on the assets alone and there is no meaningful credit enhancement. It risks failing the test and being reported outside bonds.

Where Judgement Is Needed#

Some of the hardest calls sit in the wording of the tests. What counts as "substantive" credit enhancement, and whether an issuer's operations are sufficiently separate from the assets backing a security, depend on facts and on how the statements are read. Preparers, auditors and regulators may not always view borderline structures the same way. Where a holding is borderline, document the analysis, and consider raising it with your auditor or a specialist before filing.

Practical Steps for Reclassification Work#

  • Build an inventory of holdings currently reported as bonds, with the offering documents for each.
  • Record the source of repayment for every holding in a working file.
  • Identify structured holdings where repayment depends on specific assets, and flag them for closer review.
  • Assess credit enhancement for each ABS and write down the reasoning.
  • Estimate the capital effect of any holding that may fail, so management sees the exposure early.
  • Keep the documentation so the classification can be explained to examiners and auditors.

Common Pitfalls#

  • Relying on the label in the marketing material rather than the actual repayment mechanics.
  • Treating a bare assertion of credit enhancement as sufficient without testing it.
  • Reviewing only new purchases and ignoring existing portfolios, which the article notes face a reclassification burden.
  • Leaving the reasoning undocumented, which makes the position hard to defend later.
