What does an insurance company’s AM Best rating mean? An AM Best rating is an independent assessment of an insurer’s financial strength and its ability to meet ongoing obligations to policyholders. When you see a company listed as A+, A, or B++, that grade is not a marketing slogan. It is a forward-looking opinion issued by a credit rating agency that specializes exclusively in the insurance industry. For consumers evaluating life insurance, annuities, disability coverage, long-term care, or Medicare-related products, understanding what that rating represents can be the difference between simply buying a policy and making a long-term financial decision with confidence.

At Diversified Insurance Brokers, financial strength is never an afterthought. We work with dozens of highly rated carriers and regularly evaluate insurer stability alongside product design, underwriting flexibility, and pricing competitiveness. Whether a client is exploring life insurance as part of a broader financial strategy, comparing annuities as conservative investment alternatives, or weighing group versus individual life insurance, carrier strength is always part of the discussion.

What Is AM Best?

AM Best is a global credit rating agency founded in 1899 that focuses specifically on the insurance sector. Unlike consumer review platforms or generalized financial media rankings, AM Best evaluates insurers through the lens of balance sheet strength, operating performance, business profile, and enterprise risk management. Its core objective is to assess whether an insurance company has the financial capacity to pay claims and honor guarantees not just today, but decades into the future.

This long-term perspective is especially important for products built around promises that may last 20, 30, or even 40 years. Permanent life insurance, income-producing annuities, and disability income policies all depend on the issuing carrier’s ability to maintain reserves, manage risk, and adapt to changing economic environments. When consumers ask whether annuities are worth it or whether life insurance is a good investment, the answer is inseparable from the financial health of the insurer backing the contract.

What an AM Best Rating Actually Measures

An AM Best rating reflects a multi-layered evaluation process. Analysts examine the insurer’s balance sheet, including capital adequacy, reserve levels, asset quality, and liquidity. They analyze operating performance over time, looking at underwriting profitability, expense management, and return on equity. They review the company’s business profile, including market diversification, product mix, and distribution strength. They also evaluate enterprise risk management practices, stress testing capabilities, and exposure to economic or catastrophic events.

The result is a forward-looking opinion on financial strength. This is not simply a snapshot of last quarter’s profits. It is a projection of how resilient the company is likely to be under adverse scenarios such as economic downturns, interest rate volatility, or elevated claims experience. For policyholders, this matters because insurance is fundamentally a contract built on trust in long-term performance.

Understanding the AM Best Rating Scale

The AM Best Financial Strength Rating scale ranges from A++ at the top down to ratings that indicate vulnerability. Companies rated A++ or A+ are considered “Superior,” reflecting exceptional financial strength and claims-paying ability. Insurers rated A or A- fall into the “Excellent” category, demonstrating strong capacity to meet ongoing obligations. Ratings of B++ or B+ are categorized as “Good,” meaning the insurer is financially stable but may be more sensitive to economic stress. Lower ratings indicate increasing levels of financial vulnerability.

In most long-term planning contexts, particularly when evaluating permanent policies or lifetime income products, advisors tend to focus on carriers rated A- or better. That threshold provides a meaningful level of financial confidence while still allowing flexibility to compare pricing and product features. When reviewing specific carriers, such as in our analysis of The Hartford or Transamerica, financial ratings are a core part of the evaluation process.

Why Financial Strength Matters So Much

An insurance policy is not a short-term purchase. It is a legal promise that may extend across decades. While state guaranty associations provide limited backstop protection in the rare event of insurer insolvency, those protections are capped and vary by state. They are not designed to replace the security of a financially strong carrier. Relying solely on guaranty associations rather than prioritizing carrier quality can introduce unnecessary uncertainty.

This is particularly important in markets where underwriting complexity intersects with long-term guarantees. Clients seeking life insurance with pre-existing conditions often need both underwriting flexibility and strong financial backing. The same is true for individuals comparing annuities as conservative planning tools or analyzing whether annuities fit their retirement income needs. Product design and financial strength must work together.

How AM Best Differs From Other Rating Agencies

Agencies such as Moody’s, Standard & Poor’s, and Fitch also issue financial ratings, including for insurance companies. However, AM Best’s specialization in the insurance sector gives it a distinct analytical framework. Its methodologies are built specifically around underwriting cycles, reserve adequacy, reinsurance structures, and regulatory capital requirements unique to insurers. That sector-specific expertise makes AM Best particularly influential in the insurance marketplace.

For consumers, the key takeaway is that multiple rating agencies may evaluate the same company, and reviewing more than one opinion can provide additional context. Nevertheless, AM Best remains one of the most recognized benchmarks within the life and annuity industry.

Does a Higher Rating Automatically Mean a Better Policy?

A higher AM Best rating indicates stronger financial capacity, but it does not automatically make one policy superior to another. Coverage terms, premium structure, rider availability, dividend history, underwriting approach, and customer service all matter. Two insurers may both carry A ratings yet differ significantly in pricing or policy flexibility.

This is why independent analysis is critical. At Diversified Insurance Brokers, we balance financial strength with practical considerations. When a client is deciding between group and individual life insurance, or evaluating whether permanent life insurance aligns with long-term goals, we compare both the insurer’s rating and the structural details of the policy itself.

Do AM Best Ratings Change?

AM Best ratings are reviewed periodically and can change over time. Mergers, acquisitions, shifts in capital structure, adverse claims trends, or broader economic stress can all influence future ratings. Upgrades and downgrades are part of the natural evolution of the insurance marketplace. For long-term policyholders, staying informed about carrier developments is prudent, particularly when large death benefits or significant annuity balances are involved.

Our advisory process includes ongoing awareness of industry developments so clients are not left in the dark about changes in insurer stability years after a policy is issued.

How We Integrate Ratings Into Our Process

Financial strength is one filter among several. We begin by screening for strong carriers, typically focusing on those rated A- or better. From there, we compare underwriting appetite, pricing structure, product design, and suitability for the client’s objectives. A client evaluating annuities for principal protection may prioritize long-term stability and guarantees, while someone assessing cash value life insurance may balance dividend performance with carrier strength.

The goal is not to chase the single highest rating at the expense of fit. Instead, we align strong carriers with well-designed solutions tailored to each client’s financial plan.
