Some insurance companies are structured as a risk retention group (RRG), and if you're getting a quote from one, the price is probably lower than what you've seen elsewhere. Risk retention groups operate under different rules than traditional carriers, and some of those differences genuinely work in your favor. Others matter most when something goes wrong.

Understanding how a risk retention group is built, what it can cover, how it's regulated, and what backstops it doesn't have is what lets you evaluate one honestly against the alternative. The structure isn't inherently dangerous but it's different enough that the comparison isn't just about price.

Key Takeaways

  • A risk retention group is a member-owned liability insurer created under the federal Liability Risk Retention Act of 1986. Policyholders are also owners.
  • RRGs can only write liability insurance. Property coverage, workers' compensation, and personal lines are excluded by federal law.
  • An RRG licensed in one state can operate across all 50 without separate state licensing.
  • RRG policyholders do not have access to state insurance guaranty funds, so if an RRG fails claims are paid from remaining assets only.
  • Only 44 of the 222 active RRGs in the U.S. carry an A.M. Best financial strength rating.

What Is a Risk Retention Group?

A risk retention group is a liability insurance company owned by the businesses it insures: the policyholders are also the owners. They capitalize the insurer, share in its financial results, and bear more of its risk than a traditional insurance customer would.

Under the Liability Risk Retention Act of 1986 (LRRA), an RRG must be chartered and licensed as a liability insurance company, owned by its member-insureds, and open only to businesses engaged in "similar or related businesses or activities" that expose them to similar liabilities. 

According to Pinnacle Actuarial Resources' 2025 Risk Retention Group Benchmarking Study, 222 RRGs operated in the U.S. with positive written premium in 2024, generating roughly $5.45 billion in total premium. That represents about 0.5 percent of all direct written commercial premium. RRGs are a specialized tool for specific markets, not typically seen as a mainstream alternative to the traditional insurance system.

How RRGs Differ from a Traditional Insurance Company

Three differences matter most to a buyer evaluating an RRG against a traditional carrier option.

Liability Insurance Only

The LRRA restricts RRGs to liability insurance, and can’t directly offer property coverage, workers' compensation, or personal lines. It means a company that buys from an RRG still needs traditional carriers for every line of coverage outside liability. That includes the property coverage on your office space, the workers' comp required by your state, and any other first-party protection.

One carrier for liability and others for other lines can mean mismatched renewal dates, multiple relationships to manage, and gaps that only appear when a claim lands in the space between policies.

Regulatory Structure: One Domicile, Limited Oversight Elsewhere

A traditional admitted insurer is licensed and examined by every state where it writes business. An RRG is licensed and primarily regulated by one domiciliary state. 

Other states can't block a properly registered RRG from operating or impose full state licensing requirements, but they can require registration and collect premium taxes, and they retain the right to enforce unfair claims practices laws and conduct financial examinations if the domicile won't act.

The Ownership Dynamic

In a traditional insurance arrangement, you're a customer. The carrier pays your claim from its own capital.

In an RRG, you're a member of the pool that pays claims. In good years, it may mean dividends or premium stability. At other times, that may mean assessments are possible if the pool is underfunded.

Why Do Risk Retention Groups Exist?

In the late 1970s and mid-1980s, carriers sharply reduced appetite for product liability, medical malpractice, and other specialty liability lines. The result: manufacturers, physicians, and other industry groups couldn't get coverage at any price, or only at prices that threatened to put them out of business.

The LRRA's solution was federal preemption. An RRG licensed in its domiciliary state can operate across all 50 states without going through full licensing in each one. It files a registration form in non-domiciliary states and can begin operating without waiting for formal approval, and those states can't reject a complete registration or use the process as a de facto licensing gate.

That preemption creates real economic advantages for niche markets underserved by the admitted market: lower administrative costs, faster market entry, and the ability to develop specialized underwriting criteria and policy forms tailored to a single industry without needing 50-state regulatory approval. 

Risk Retention Group vs. Captive vs. Purchasing Group

These three structures often appear in the same conversation. They're related but meaningfully different.

Risk Retention Group Captive Purchasing Group
Bears insurance risk? Yes Yes No
Multi-state authority Federal preemption after one-state registration State-by-state licensing or fronting required Federal preemption for group purchasing
Coverage allowed Liability only Any line the domicile permits Liability only
Who owns it Member-policyholders Parent company or affiliated group No insurer ownership
Guaranty fund protection No Varies by domicile Depends on the insurer behind it

A purchasing group is a collective buyer. It's not an insurer and it doesn't bear insurance risk. A group of businesses in the same industry joins together to purchase liability coverage as a group, which can improve pricing and access, but the insurer behind a purchasing group is a separate entity.

A captive insurer is formed by a business or group of businesses to insure their own risks. It's a real insurer, and it can write a wider range of coverage than an RRG. But captives typically need state-by-state licensing or an arrangement with another carrier (often called “fronting”) to write business across multiple states.

An RRG is also a real insurer, owned by its member-policyholders, with the federal preemption that lets it operate nationwide after one domiciliary license. The primary tradeoff is the liability-only restriction.

The Tradeoff Every Insurance Buyer Should Understand

The lower price from an RRG often reflects a real structural difference, not just efficiency. Here's where the comparison with traditional coverage gets specific.

No Guaranty Fund Protection

If an insurer goes bankrupt, admitted carriers can pay claims through the guaranty fund, but that option doesn't exist with an RRG.

When a traditional admitted insurer becomes insolvent, state insurance guaranty funds step in to pay covered claims up to statutory limits. For most property and casualty claims, the standard limit under the NAIC model is $300,000 per claim, though limits vary by state and coverage type. It's an industry-wide backstop that exists specifically to protect policyholders when their carrier fails.

RRG policyholders don't have that protection. The LRRA explicitly prohibits RRGs from participating in state guaranty funds, and every RRG policy must include a disclosure to that effect.

When an RRG fails, claims are paid from its remaining assets and reinsurance. If those run out before your claim is paid, your recourse is limited to whatever is left in receivership.

The Ratings Gap

An A.M. Best rating is independent verification that a carrier's financial strength meets a published standard. It's external scrutiny of reserves, capital adequacy, and the ability to pay future claims. It's also what most enterprise contracts, commercial leases, lender agreements, and vendor requirements use as the proxy for "will this insurer actually be able to pay?"

Only 44 of the 222 RRGs with positive written premium in 2024 carried an A.M. Best financial strength rating, according to Pinnacle's 2025 benchmarking study.

Unrated doesn't automatically mean unsafe. Some unrated RRGs are well-capitalized and responsibly run. But when a carrier is unrated, the burden of due diligence falls entirely to the buyer. There's no independent agency that has done the work of evaluating financial strength and published its conclusion. You're doing that yourself, or you're not doing it at all.

In Vouch advisor conversations, the A.M. Best requirement comes up regularly as a contractual gate. Across SaaS, AI, Fintech, and HealthTech companies, enterprise partners, landlords, and investors often specify minimum A.M. Best ratings, typically A- or better, as a condition of doing business. A quote from an unrated RRG won't satisfy that requirement regardless of its actual financial health.

What RRG Failure Has Looked Like

RRG failures aren't common, but they happen, and they're instructive about what the absence of a guaranty fund looks like in practice.

Spirit Commercial Auto RRG was placed into liquidation in 2019 after its total unpaid claims and loss adjustment expenses, estimated at approximately $199 million, far exceeded the roughly $42 million in assets available to pay them. Members whose claims were pending at liquidation had their recovery limited to the assets remaining in the estate, with no guaranty fund available to fill the gap.

CARE RRG, a medical professional liability insurer covering more than 1,300 physicians, was placed into rehabilitation by the Vermont Department of Financial Regulation in April 2025 after a single arbitration judgment of $35.4 million against it exceeded the company's entire capital and surplus of $3.5 million. All in-force policies were canceled and claims payments were paused, leaving members to find replacement coverage immediately.

Well-governed, adequately capitalized RRGs with strong reinsurance can operate successfully for decades. But the structural reality is that a single large judgment or bad claims year can threaten a pool in ways that a traditional carrier backed by guaranty fund protections can absorb differently.

Who RRGs Work Well For and Where Traditional Coverage Is Better

When RRGs Make Sense

RRGs perform best for industry groups with homogeneous liability exposures, genuine multi-state operations, and limited access to the traditional admitted market.

Medical professional liability remains the largest RRG market by far, at roughly $2.96 billion of the $5.45 billion total in 2024, according to Pinnacle. Commercial auto liability follows at approximately $616 million. Public entities, senior care facilities, and specialized professional associations round out the market. What these groups share: a narrow, well-defined exposure profile; a hard market history that pushed them toward alternative structures; and the benefit of underwriting tailored to their specific risks.

For buyers in those markets, an RRG can offer coverage forms that no admitted carrier has developed for them, pricing that reflects actual loss experience from a homogeneous pool, and member governance over how claims are handled and risks are managed.

When Traditional Coverage Is Usually the Better Fit

For most growth-stage technology, professional services, and financial services companies, traditional broker-placed coverage with a rated carrier is the more reliable foundation.

Contract requirements are the most immediate practical issue. COI requirements blocking or gating a business contract appears often in Vouch calls with clients, making it one of the most common practical pain point in that dataset. An unrated RRG certificate of insurance is precisely the scenario where this materializes: the contract language specifies an A.M. Best-rated carrier, the RRG doesn't meet that threshold, and the deal stalls.

The multiline problem is the second issue. A growing company needs property coverage, workers' compensation, Directors & Officers Insurance, Cyber Insurance, and Errors & Omissions Insurance in addition to General Liability. An RRG can cover the liability side. Everything else still needs a traditional carrier. Managing multiple carriers with separate renewal dates and different underwriting teams creates coordination risk, especially as the business changes quickly and coverage needs to keep pace.

Finally, a well-structured commercial insurance program through a broker can be adjusted as a company raises capital, adds headcount, expands geographically, or takes on enterprise contracts with specific coverage requirements. An RRG membership is harder to exit cleanly and may not adapt as fluidly to the company's changing risk profile.

What to Ask Before Buying from an RRG

Buying from an RRG requires more active evaluation than buying from a traditional rated carrier, because the external backstops that normally do part of the diligence work aren't there. These are the questions that matter.

  1. Is it rated, and by whom? If the RRG carries an A.M. Best or Demotech rating, start there. If not, understand that you're taking on the due diligence those agencies would otherwise perform.
  2. What do the audited financials show? RRGs are required to file annual audited financial statements and actuarial reserve opinions with their domiciliary state regulator. Look at surplus trends, loss reserve development over multiple years, and net-written-premium-to-surplus ratios. Deteriorating surplus or adverse reserve development over multiple periods is a warning sign.
  3. Who handles claims, and what does the reinsurance structure look like? Many RRGs use third-party administrators for claims. The quality of that relationship matters. The reinsurance stack is the backstop when individual claims spike. Ask about net retention per risk and the financial quality of the reinsurers supporting the program.
  4. Will it satisfy your contract, lease, or lender requirements? Pull the actual language before assuming the coverage qualifies. "An admitted, A.M. Best-rated carrier at A- or better" is a common standard that many unrated RRGs can't meet.
  5. Are assessments possible? In a member-owned insurer, your premium may not be the ceiling of your financial obligation. If the pool is underfunded after a bad claims year, some RRG structures allow for assessments on members. Understand whether that's possible and under what conditions before you commit.

If you're comparing an RRG quote to traditional alternatives, a Vouch advisor can help you evaluate what you're actually trading away and whether rated, broker-placed coverage is the right fit for your business.

Risk retention groups aren't the wrong answer for every buyer. For niche liability markets underserved by the traditional market, the right RRG can provide genuine value. But the right buyer is narrower than the price difference alone suggests. For most growing companies with enterprise contracts, investor requirements, or multiline coverage needs, the tradeoffs tip toward rated, broker-placed coverage that can clear contractual requirements, absorb the company's growth, and leave the guaranty fund backstop in place if it's ever needed.

Frequently Asked Questions

Can a Risk Retention Group Write Property Insurance?

No. The Liability Risk Retention Act restricts RRGs to liability insurance only. Property coverage, workers' compensation, and personal lines are excluded by federal statute, not by carrier preference. If your business needs property coverage, you'll need a traditional carrier for that line regardless of whether you're also buying liability coverage from an RRG.

What Happens to Your Claims If My RRG Becomes Insolvent?

Claims are paid from the RRG's remaining assets and reinsurance. There's no state insurance guaranty fund backstop: the LRRA explicitly prohibits RRG participation in guaranty funds, and every policy is required to disclose this. If the remaining assets are insufficient to cover all claims, your recovery is limited to your share of what's left. This is meaningfully different from the outcome with a traditional admitted carrier, where guaranty funds typically cover property and casualty claims up to $300,000 per claim, even if the carrier fails.

Is an RRG the Same as a Captive Insurance Company?

No. Both are member-controlled insurance structures where the insured businesses have an ownership stake. The key difference is that an RRG gets federal preemption to write liability coverage nationwide after licensing in one domiciliary state. Most captives need state-by-state licensing or a fronting arrangement for multi-state business. RRGs are also restricted to liability only; captives can typically write other lines, including property, depending on domicile rules.

Why Won't My Landlord or Enterprise Customer Accept My RRG Certificate of Insurance?

Most commercial leases, loan agreements, vendor contracts, and enterprise partnership agreements specify that coverage must come from an A.M. Best-rated carrier, often at a minimum financial strength rating of A- and a size category of VII or above. If your RRG doesn't carry a qualifying A.M. Best rating, the certificate won't satisfy the requirement regardless of the RRG's actual financial health.

Are Risk Retention Groups Regulated?

Yes. The domiciliary state oversees formation, ongoing solvency, financial examinations, and annual filings including audited financial statements, actuarial reserve opinions, and risk-based capital reports. Non-domiciliary states have more limited authority: they can require registration, collect premium taxes, and enforce unfair claims practices law, but they can't block a registered RRG from operating or impose full state licensing requirements.

How Do I Evaluate Whether an RRG Is Financially Sound?

Start with whether it carries an A.M. Best or Demotech rating. For unrated RRGs, request audited financial statements filed with the domiciliary state regulator and look for surplus growth trends, stable or improving loss reserve development, and a conservative net-written-premium-to-surplus ratio. Ask about reinsurance quality and net retention per risk. Also ask directly whether assessments on members are possible under the structure and, if so, under what conditions.
