Quick Summary
Insurer financial strength refers to an insurance company's capacity to meet its obligations to policyholders, including the ability to pay claims and deliver promised income even during economic downturns. You can evaluate it by reviewing ratings from AM Best, S&P Global Ratings, and Moody's, checking regulatory solvency data like risk-based capital ratios, and examining the insurer's financial statements and complaint history.
AM Best rates insurers on a scale from A++ (superior) to D (poor), with most major insurers in the A+ to A range.
State regulators use risk-based capital ratios and IRIS financial ratios to monitor insurer solvency independently of rating agencies.
State guaranty associations provide limited coverage for annuity benefits if an insurer becomes insolvent, though limits vary by state.
Compare insurers using the same rating agency, check for rating downgrades or negative outlooks over recent years, and review reserve adequacy and liquidity trends.
A licensed professional can help you interpret financial metrics for a specific annuity contract and explain how guarantees depend on the issuing insurer's financial strength.

Why Insurer Financial Strength Matters for Annuity Holders
An annuity is a long-term commitment. The insurer promises to pay income, sometimes for life, and that promise depends on the company's ability to keep it. (Source: National Association of Insurance Commissioners (NAIC))
Insurer financial strength refers to an insurance company's capacity to meet its obligations to policyholders.
For annuity holders, this matters.
According to the National Association of Insurance Commissioners, insurer financial-strength ratings help assess an insurer's ability to meet policy and contract obligations.
AnnuityTown provides educational resources to help you understand these ratings. A licensed professional can help evaluate a specific insurer's financial strength.
Understanding AM Best Insurance Ratings Explained
What the ratings mean:
AM Best uses a scale from A++ (superior) down to D (poor). Most major insurers carry ratings in the A+ to A range. Here's how to read them:
- A++ or A+: Superior financial strength. The insurer has strong capital and profitability.
- A or A-: Excellent financial strength. The insurer is well-positioned to meet obligations.
- B++ or B+: Good financial strength. The insurer is capable but has less cushion than higher-rated peers.
AM Best also assigns outlooks, stable, positive, or negative, that signal whether a rating may change in the near term.
Learn how to read insurer financial strength ratings to compare agency scales and check outlooks.
Higher-rated insurers have shown stronger capital reserves and lower historical risk of failure, but ratings change and can be downgraded if business conditions shift.
AM Best uses a letter-grade scale to rate insurer financial strength, with higher grades indicating stronger capacity to pay claims.
| Rating | Financial Strength | Capital Position |
|---|---|---|
| A++ or A+ | Superior | Strong capital and profitability |
| A or A- | Excellent | Well-positioned to meet obligations |
| B++ or B+ | Good | Capable with less cushion than higher-rated peers |
| B or B- | Adequate | Meets obligations but faces moderate risk |
| Below B- | Weaker | Higher risk of payment failure |
How to Compare Insurance Company Ratings
Comparing ratings across insurers requires looking beyond a single letter grade. Multiple agencies rate insurers, and their scales differ.
Three major rating agencies:
- AM Best: Focuses on financial strength and claims-paying ability. Ratings range from A++ to D.
- S&P Global Ratings: Provides insurer financial strength ratings as a forward-looking opinion about the insurance organization's ability to pay policies and contracts. Ratings range from AAA to D.
- Moody's Investors Service: Rates insurers on their ability to meet obligations. Scale ranges from Aaa to C.
Why the scales differ: Each agency uses its own methodology.
What to check:
- The rating itself (letter grade)
- The outlook (stable, positive, or negative)
- The date the rating was issued
An insurer rated highly by one agency but lower by another may warrant closer inspection.
The National Association of Insurance Commissioners notes that not all insurer financial strength ratings are created equal.
Assessing Insurance Company Claims-Paying Ability
A high rating tells you an insurer has strong capital. What does that mean for your annuity payments?
Claims-paying ability is the insurer's demonstrated capacity to pay claims on time, even during stress. It is related to, but distinct from, financial strength.
The Regulatory Backstop: Risk-Based Capital and IRIS
State insurance regulators do not rely on rating agencies alone. They run their own solvency tests, and much of that data is public.
- Risk-based capital (RBC): Insurers report an RBC ratio that compares adjusted capital to the minimum capital regulators require for the risk the company has taken on. A ratio comfortably above the regulatory threshold signals a cushion; a ratio near the threshold can trigger closer regulatory attention. The NAIC publishes the formula and the ratio appears in annual statement data.
- IRIS ratios: The NAIC's Insurance Regulatory Information System applies a set of financial ratios, covering liquidity, reserve adequacy, profitability, and leverage, and flags companies that fall outside expected ranges. A single outlier is not necessarily alarming, but multiple flags can prompt a state insurance department to examine the insurer more closely.
- Annual and quarterly statements: Insurers file detailed financial statements with state regulators. These show assets, liabilities, reserves, premium, and claims experience. The NAIC's database and many state insurance department websites make portions of this data available to the public.
State Guaranty Association Coverage
If an insurer becomes insolvent, state guaranty associations provide a limited backstop for policyholders of licensed insurers. These associations are created under state law, and coverage limits and rules vary by state and product type.
Key points to understand about guaranty association coverage:
- It is a backstop of last resort, not a substitute for insurer strength.
- Limits apply per person, per insurer, and sometimes per beneficiary or contract type.
- It generally does not cover certain products or contract features, and it does not protect against market losses.
A licensed professional can help you confirm the current coverage limits and rules that apply in your state and how they would interact with a specific contract.
Other Indicators Worth Reviewing
- Reserves: Annuity obligations require reserves set aside to meet future payments. Reserve adequacy relative to the block of business is a core solvency measure.
- Liquidity: Can the insurer meet cash demands without forced asset sales? Poor liquidity can disrupt payments even when the company is technically solvent.
- Reinsurance arrangements: Insurers often transfer part of their risk to reinsurers. Strong, long-standing reinsurance relationships can support stability, but they also mean part of the promise depends on the reinsurer's own financial strength.
How These Pieces Fit Together
A rating is a summary opinion. RBC ratios, IRIS flags, reserve adequacy, and guaranty association limits are the underlying machinery. Read together, they give a clearer picture of whether an insurer's promise is backed by capital and monitored by regulators.

Key Steps to Evaluate Insurance Company Financial Stability
Here is a practical, repeatable process for assessing an insurer's financial stability, giving you a consistent basis for comparison rather than a single score.
Step 1: Pull the Current Ratings From Each Major Agency
Start with the insurer's current ratings from AM Best, S&P Global Ratings, and Moody's. Record the letter grade, the outlook, and the date of the most recent action. Use the same agency's scale when comparing two insurers; an A from one agency does not equal an A from another.
Step 2: Check Rating History and Direction
A current grade matters less than its direction. Look for downgrades, negative outlooks, or watches over the past few years. A single downgrade is not disqualifying, but a pattern of deterioration is a signal to examine the underlying financials.
Step 3: Read the Regulatory Solvency Data
Go beyond ratings to the regulatory measures described earlier:
- The insurer's risk-based capital ratio and whether it sits comfortably above the regulatory threshold.
- Any IRIS ratio flags in recent NAIC data.
- Reserve adequacy relative to the annuity block.
These are the numbers state regulators use, and they are often available through the NAIC or your state insurance department.
Step 4: Review the Insurer's Financial Statements
Annual and quarterly statements show total assets and liabilities, premium income, claims paid, and capital. Look for trends: growing assets, stable or improving capital, and reserves that keep pace with obligations.
Step 5: Check Complaint and Enforcement History
State insurance departments publish complaint ratios and enforcement actions. A high complaint ratio relative to peers, or a history of market-conduct actions, can matter even when financial ratios look strong. Financial strength and fair dealing are different questions, and both affect the experience of holding a contract.
Step 6: Assess Business Mix and Interest-Rate Exposure
An insurer concentrated in annuities with long-dated guarantees is sensitive to interest-rate changes. A diversified insurer may have more stable earnings but can carry risks from other lines. Ask how product mix and asset-liability management affect the guarantees under consideration.
Step 7: Map Guaranty Association Coverage to Your Contract
Confirm the current coverage limit in your state and how it applies to the annuity type and ownership structure you are considering. If a contract's value would exceed the limit, that is a factor a licensed professional can help you weigh alongside the insurer's rating and capital position.
Step 8: Compare Insurers on the Same Basis
When you have two or more candidates, put the same data side by side:
- Rating and outlook from the same agency
- RBC ratio and any IRIS flags
- Reserve and liquidity trends
A written comparison of this kind is also useful when an existing annuity is being considered against a proposed contract. Replacement can restart surrender periods, change guarantees, create compensation, affect taxes, and remove existing benefits, so a side-by-side review of the old and proposed contracts, including guarantees, fees, surrender schedules, compensation, taxes, and benefits that would be lost, is worth requesting in writing.
What This Method Does and Does Not Do
This process organizes public information so you can see how an insurer's promise is backed. It does not eliminate insurer credit risk, and it does not determine whether any contract is appropriate for your circumstances. A licensed professional can evaluate these factors against your situation.

Using Insurer Strength in Your Annuity Decision
When evaluating an annuity, insurer financial strength is one factor among many. A strong insurer doesn't make a weak contract good. A weak contract doesn't become acceptable just because the insurer is strong.
Consider these elements together:
- Insurer rating: A+ or higher is generally considered strong. Lower-rated insurers carry higher risk.
- Guarantees: What is the insurer actually guaranteeing? Income amount? Duration? Withdrawal options? Read the contract carefully.
- Fees and costs: Annuities carry various fees, mortality and expense charges, investment management fees, and rider costs. These reduce your returns or income.
A licensed professional can help you evaluate how insurer strength fits into your overall retirement strategy.
When comparing annuity quotes from different insurers, ask for side-by-side comparisons that include:
- Insurer rating and outlook
- Guaranteed income or benefit amount
- Fees and costs
This allows you to see how financial strength, costs, and guarantees compare across options.

What does an insurer financial strength rating mean?
An insurer financial strength rating is an independent assessment of a company's ability to pay its obligations, including annuity payments and insurance claims. Ratings are based on financial analysis, capital reserves, and risk factors. S&P Global, for example, describes its Insurer Financial Strength Rating as a forward-looking opinion about an insurance organization's ability to pay its policies and contracts. Ratings help you understand whether an insurer has the resources to honor its commitments over decades.
How do you evaluate an insurance company's financial strength?
Start by checking ratings from agencies like AM Best, S&P Global, Moody's, or Fitch. Review the insurer's financial statements and Own Risk and Solvency Assessment (ORSA) reports, which the National Association of Insurance Commissioners requires insurers to file. Examine capital adequacy, loss reserves, and reinsurance arrangements. Look at the company's history with regulators and complaint records. A licensed professional can help you interpret these data points in the context of your specific situation.
What is a good financial strength rating for an insurer?
Ratings vary by agency and scale, so compare apples to apples. Most agencies use letter grades where A-level ratings indicate strong financial strength, while lower grades suggest higher risk. The National Association of Insurance Commissioners notes that not all insurer financial strength ratings are created equal, so understand the methodology behind each rating. A licensed professional can explain what a specific rating means for the insurer you are considering and how it affects your protection.
Do insurance company ratings guarantee that claims will be paid?
Ratings do not guarantee payment. They reflect an agency's opinion at a point in time based on available data. Guarantees in an annuity contract depend on the contract terms and the issuing insurer's financial strength and claims-paying ability. While a strong rating suggests lower risk, insurers can face unexpected challenges. State insurance regulators oversee insolvency protections, but coverage limits and rules vary by state. A licensed professional can explain your state's protections and help you weigh insurer strength as one factor in your decision.
