You've received two quotes. The coverage looks similar. The limits are the same. But one is cheaper. Before you sign, there's one question worth asking: when you file a claim, will the money be there?
That question isn't about customer service ratings or claims turnaround time. it's about whether the carrier writing your policy has the financial reserves to pay a complex, multi-year claim, potentially years from now and under adverse conditions. That's what an insurance carrier rating measures. It's not a marketing credential but an independent actuarial assessment of whether a carrier can meet its obligations over time.
For growth-stage companies, this distinction tends to surface at the worst moments: when an enterprise contract won't close because the COI carrier fails procurement review, or when a fundraise stalls because investors require D&O Insurance from a rated carrier and the policy you already have doesn't qualify. Understanding carrier ratings before those moments is considerably easier than navigating them during.
Key Takeaways
- An insurance carrier rating, most commonly issued by A.M. Best, reflects a carrier's ability to pay claims over time, not just a snapshot of today's finances.
- Admitted carriers contribute to state guaranty funds, which provide a backstop if a carrier fails. Non-admitted carriers do not. These are separate from, but related to, carrier financial strength ratings.
- Enterprise contracts and investor due diligence typically require a minimum A.M. Best rating, usually A- or better. A policy from an unrated carrier will not satisfy these requirements.
- A cheaper quote from an unrated carrier isn't a better deal. The price difference often reflects cost structures that rated, admitted carriers maintain to provide those protections.
- Carrier selection is part of what a broker does. You shouldn't have to evaluate financial strength ratings on your own.
What "Rated" Actually Means
When people refer to a carrier's rating, they're almost always referring to a Financial Strength Rating (FSR) issued by A.M. Best, a rating agency that has evaluated insurance companies since 1899 and covers the insurance industry exclusively. Other major agencies, including Moody's, S&P Global, and Fitch, also rate insurers, but A.M. Best is the standard that appears in enterprise vendor contracts, investor side letters, and insurance procurement requirements.
A.M. Best's rating scale runs from A++ (Superior) down to D (Poor). The categories that matter most for commercial buyers:
- Superior: A++ or A+
- Excellent: A or A-
- Good: B++ or B+
Most enterprise contracts set A- as the floor. Companies without any rating have not been independently reviewed at all.
In addition to the letter grade, A.M. Best assigns a Financial Size Category expressed as a Roman numeral from I to XV, based on the carrier's adjusted policyholder surplus: the financial cushion available to pay claims. Size category VIII, for example, indicates a surplus of $100 million to $250 million.
Many contracts specify both, something like "A- VIII," meaning the carrier must be rated Excellent by A.M. Best and carry at least $100 million in surplus. A carrier can be well-rated but too small to absorb a significant claim at scale, which is why both matter.
What A.M. Best actually evaluates is:
- Balance sheet strength (reserves, asset quality, the relationship between assets and liabilities)
- Operating performance (pricing consistency and loss ratios over time)
- Business profile (management depth, market discipline, operational resilience)
What it doesn’t evaluate:
- Claims speed
- Customer service
- Digital experience
What a Carrier Rating Actually Predicts
Insurance isn’[t a transaction that closes at purchase. When you pay a premium, you're buying a commitment to a future event that may not occur for months or years. A D&O claim filed by a departing executive can develop over two years of discovery and litigation. A Cyber Insurance claim triggered by a breach may generate costs through a third wave of regulatory inquiries. An E&O dispute over work delivered 18 months ago may land precisely when a carrier is navigating its own financial stress.
The financial position of the carrier at the time of the claim determines whether you get paid, not its position when you bound the policy. That's why A.M. Best ratings look forward: they assess whether a carrier has the capital to absorb large losses, maintain reserves through adverse conditions, and honor long-tail obligations, not just whether it's solvent today.
An unrated carrier is one that hasn’t undergone independent third-party financial review, chose not to seek one, or couldn’t obtain one. That doesn't mean it's insolvent, but does mean the buyer doesn’t have independent validation of its claims-paying ability and is relying entirely on the carrier's self-reported financials.
For routine claims at small dollar amounts, this might be manageable. For the kinds of claims growth-stage companies actually face, the financial depth of the carrier matters in ways that only become visible at the moment they're needed.
What You May Give Up Without a Rated Carrier
Not every protection a buyer assumes they have is present in every policy. Some protections depend specifically on carrier status. Here's what can change when coverage is placed with an unrated or non-admitted carrier.
The State Guaranty Fund Backstop
Admitted carriers are licensed in each state where they operate and are required to contribute to state guaranty funds, which function as a safety net for policyholders if a carrier fails. If an admitted carrier becomes insolvent, the guaranty fund steps in to cover claims up to the state's limit. For most commercial lines, that limit is $300,000 per covered claim under the NAIC's model guaranty fund framework, though actual limits vary by state.
Non-admitted carriers, often called surplus lines carriers, are not required to contribute to state guaranty funds. If a non-admitted carrier fails, there is no state backstop. Policyholders become unsecured creditors in the insolvency proceeding.
This is an important distinction that frequently surprises buyers: admitted status and A.M. Best rating are two separate questions. A carrier can be non-admitted and still have an A.M. Best rating. A carrier can be admitted and have a poor rating. The A.M. Best rating addresses the carrier's financial strength; admitted status addresses whether the state guaranty fund applies. Both are worth checking.
For buyers evaluating coverage structured as a risk retention group, it's worth knowing that fewer than a third of operational RRGs carry any independent financial strength rating, and even fewer carry a rating of A or better from A.M. Best. Many are also non-admitted, meaning the combination of no rating and no guaranty fund backing represents the widest gap in policyholder protection.
Enterprise Contract and COI Acceptance
For growth-stage companies, the carrier rating question often becomes tangible at a specific moment: when an enterprise contract asks for a Certificate of Insurance and the procurement team checks the carrier.
Enterprise vendor agreements and partnership contracts routinely include insurance requirements specifying a minimum carrier rating. A.M. Best A- is the most common threshold. This isn't a preference; it's a contractual compliance requirement. A COI from a non-rated carrier will fail that check, and the deal stalls until coverage is updated or the contract requirement is renegotiated.
Investor due diligence can create the same requirement on the D&O side. D&O conversations triggered directly by investor or fundraising requirements. When business owners noted that their enterprise contract specified a minimum carrier rating, A.M. Best is almost always named as the standard. Buyers typically discover this requirement when they're already mid-deal.
Regulatory Oversight of Admitted Carriers
Admitted carriers file their rates and policy forms with state insurance regulators, creating a layer of accountability beyond A.M. Best's assessment. Non-admitted (surplus lines) carriers operate under lighter-touch oversight from surplus lines regulators, with fewer consumer protection requirements.
For most technology companies buying standard coverage lines like D&O, Cyber Insurance, or Errors & Omissions Insurance, admitted carrier placement is typically achievable and generally preferred where it's available.
"But It's Cheaper": What the Price Difference Represents
When a competing quote comes in 20 or 30% cheaper, that gap almost always represents something real. Rated, admitted carriers price in the cost of maintaining the reserves A.M. Best evaluates, contributing to state guaranty funds, and sustaining the compliance infrastructure that comes with admitted status. Those costs aren’t free.
A carrier that doesn't bear those obligations can price lower because it isn't carrying them. The cheaper premium isn't a better deal at the same quality level; it's a structurally different product. What the buyer saves on premium is roughly what they're absorbing in terms of the missing protections.
This doesn’t mean that every non-admitted or unrated carrier is a bad choice in every situation. Non-admitted markets exist for good reasons, primarily to provide coverage for complex or unusual risks that admitted carriers won't write. A hardware company with unusual product liability exposure or a fintech company in a specialty market may end up in non-admitted markets by necessity.
But there are scenarios where the tradeoff can go wrong: when a company needs coverage that will satisfy investor diligence, clear enterprise procurement, or hold up under a large and long-tail claim. In those cases, carrier quality matters, and the price difference reflects real value.
How Vouch Approaches Carrier Selection
Evaluating carrier financial strength shouldn't fall to the buyer. It's part of what a broker does, and it happens before a quote reaches you.
When Vouch places coverage, the standard is A-rated or better (A.M. Best), with admitted carrier status the default where the coverage type and state allow. When surplus lines markets are the right fit for a specialized or complex risk, Vouch still screens for A.M. Best ratings. When going to market across multiple carriers on behalf of a client, carrier financial profile is part of the comparison summary alongside pricing and terms.
The question worth asking any broker: what carriers are you placing with, and what is their A.M. Best Financial Strength Rating and Financial Size Category? That answer should be available without digging through policy documents.
If you're ready to review your current coverage or get a quote from carriers that meet this standard, our advisors can walk you through the options.
Carrier ratings may feel like a technical detail. They tend to matter most in the situations where insurance matters most: the close of a funding round, the signing of an enterprise contract, the filing of a large and complex claim. Getting the carrier right is worth doing once, before those moments arrive.
Frequently Asked Questions
What is the A.M. Best rating scale for insurance carriers?
A.M. Best rates insurance companies on a scale from A++ (Superior) to D (Poor). Companies rated A- or better, classified as Excellent, are generally considered financially strong and capable of meeting their obligations over time. A.M. Best also assigns a Financial Size Category using Roman numerals from I to XV, based on adjusted policyholder surplus.
What is the difference between an admitted and a non-admitted insurance carrier?
Admitted carriers are licensed by state insurance regulators and required to contribute to state guaranty funds. If an admitted carrier fails, the guaranty fund can cover claims up to the state's limit. Non-admitted (surplus lines) carriers are not required to contribute, so there is no state backstop if they fail.
Does my insurance carrier's rating affect whether my COI will be accepted?
Yes, in most cases. Enterprise vendor agreements and partnership contracts routinely specify a minimum carrier rating, with A.M. Best A- as the most common threshold. A Certificate of Insurance from a non-rated carrier will fail that review. This is one of the most common ways companies discover they have a carrier problem, often mid-deal and under time pressure. Verifying carrier ratings before you need the COI is considerably easier than renegotiating a contract requirement when a deal is already in front of legal.
Is an unrated insurance carrier safe to buy from?
Not necessarily unsafe, but an unrated carrier means there's no independent third-party validation of its financial strength. You're relying on self-reported financials with no external verification. For low-dollar, short-tail claims, that may be manageable. For the kinds of claims growth-stage companies face, including multi-year D&O suits or complex Cyber Insurance incidents with regulatory follow-on costs, the carrier's long-term financial depth matters. Unrated coverage also typically won't satisfy enterprise procurement requirements or investor due diligence thresholds.
Why is one insurance quote cheaper than another for the same coverage?
Several factors can drive a price difference: different retentions, different coverage scope, and different carrier cost structures. Admitted, A-rated carriers maintain reserves for A.M. Best evaluation, contribute to state guaranty funds, and operate under state regulatory filing requirements. These have real costs. Carriers that don't bear those obligations can price lower. The cheaper premium may reflect a genuine trade-off in the protections underlying the policy. When comparing quotes, looking at carrier rating and admitted status alongside premium gives you a more complete picture.
What happens to my insurance claim if my carrier becomes insolvent?
If your carrier is admitted and fails, the state guaranty fund steps in to cover claims up to the state's limit (varies by state and coverage type; most states follow the NAIC model with a $300,000 per-claim cap for most commercial lines). If your carrier is non-admitted, there isn’t a guaranty fund backstop. You'd become an unsecured creditor in the insolvency proceeding. This distinction matters most for larger, longer-tail claims where the carrier's ability to remain solvent throughout the claim process is a real consideration.
