Financial strength matters because insurance promises can last for years or decades. A policyholder may pay a premium today and expect the insurer to pay a claim much later. Independent ratings provide one way to evaluate that long-term capacity, but they should be interpreted carefully.
What does an insurer financial-strength rating measure?
Financial-strength ratings focus on an insurer’s capacity to meet ongoing insurance obligations. Agencies analyze factors that can include capital adequacy, operating performance, reserves, reinsurance, investment risk, business profile, risk management and the financial position of the wider group.
The exact methodology differs by agency and can change over time. Ratings are opinions based on information available at the time of analysis, not guarantees of future performance.
Why AM Best, S&P, Moody’s and Fitch ratings are not directly interchangeable
The Insurance Information Institute emphasizes that each agency has its own scale, standards and distribution of ratings. An “A+” from one agency can occupy a different place in that agency’s scale than an “A+” from another. Moody’s also uses a different symbol system.
For that reason, compare the meaning and position of a rating within the issuing agency’s own scale rather than comparing letter symbols alone.
| Agency | What to verify |
|---|---|
| AM Best | Financial Strength Rating, outlook/implication and exact rated legal entity |
| S&P Global Ratings | Insurer financial-strength rating and the agency’s scale definition |
| Moody’s | Insurance financial-strength opinion and exact entity |
| Fitch | Insurer financial-strength rating, outlook and scale definition |
Check the legal insurance company, not only the brand
Large insurance brands can contain multiple underwriting companies. Your policy declarations page identifies the legal entity that actually issued the contract. A group rating, holding-company rating or rating for a sister company may not be the same as the rating of the underwriting entity.
When checking financial strength, match the insurer name and, where available, identifying information on the policy to the agency’s rated entity.
Financial-strength rating vs. credit rating
A financial-strength rating is focused on policyholder obligations. An issuer credit rating or bond rating can address the risk associated with a holding company or a particular debt obligation. They answer related but different questions and should not be substituted for one another without understanding the agency’s definitions.
Ratings vs. state insurance regulation
Private rating agencies do not replace state insurance regulators. Regulators use statutory financial reporting, examinations, risk-based capital and other solvency tools. The NAIC also notes that regulatory reliance on external credit ratings varies by asset class and has been reduced in some areas.
Why ratings can change
Ratings can be upgraded, downgraded or placed on a changing outlook or watch when an agency’s view changes. Factors can include catastrophe losses, reserve development, acquisitions, reinsurance changes, capital transactions, investment losses, rapid premium growth or changes in the operating environment.
How consumers and businesses can use ratings
- Verify the exact legal insurer on the declarations page.
- Check the rating directly with the rating agency or a current authorized source.
- Read the definition of the rating category and outlook.
- Compare more than one agency when practical because methodologies differ.
- Check whether the rating is current and whether it is under review.
- Consider policy coverage, price, claims service and regulatory status separately.
- For long-duration obligations, revisit ratings periodically rather than relying on an old marketing brochure.
What a strong rating does not tell you
A strong financial-strength rating does not tell you whether a policy covers your specific loss, whether a premium is competitive, whether the insurer’s claims service will meet your expectations, or whether an individual claim will be accepted. Those are separate questions.
Likewise, a rating is not the same as a state guaranty-association guarantee. Guaranty-association protection is governed by state law, eligibility and statutory limits if an insurer becomes insolvent.
Frequently asked questions
Is an A+ rating the same at every agency?
No. Rating scales differ, and the same symbol can occupy a different position on different scales.
Which rating agency is best?
There is no single universal answer. The agencies use different methodologies and coverage universes; using more than one source can provide broader context.
Can an insurer with a high rating fail?
A rating is an opinion, not a guarantee. Financial conditions can change and ratings can be revised.
Where can I find the insurer’s legal name?
Look at the policy declarations page, evidence of insurance or other contract documents. The consumer-facing brand may represent several underwriting companies.
