Risk Retention Groups are a specialized part of the U.S. commercial liability market. They were created to let businesses and professionals with similar liability exposures pool risk in an insurer they own. The structure is particularly important in niches where conventional liability capacity can be expensive, volatile or tailored poorly to a specialized membership.
Who owns an RRG?
NAIC guidance states that the insureds of an RRG are also owners of the group, and the owners must be insured by it. That member-owned structure distinguishes an RRG from a conventional stock insurer selling broadly to unrelated policyholders.
What types of insurance can an RRG write?
RRG authority centers on liability insurance permitted under the LRRA. It is not a general shortcut for writing every type of property and casualty coverage nationwide. The group’s plan of operation describes the liability coverages, deductibles, limits, rates and classifications it intends to offer.
How multistate operation works
An RRG is domiciled and licensed in one state. Under the LRRA, it can register in other states and write eligible liability coverage without becoming fully licensed there in the same way as a traditional multistate insurer. Federal law preempts certain non-domiciliary state requirements, although those states retain specified regulatory powers.
| RRG feature | What it means |
|---|---|
| Member owned | Policyholders and owners are linked through the group’s common liability exposure. |
| One primary domicile | The domiciliary state is central to licensing and solvency regulation. |
| Multistate registration | The group can register to operate in other states under LRRA rules. |
| Liability focus | RRG authority is aimed at commercial liability risks rather than general property insurance. |
| No state guaranty fund | LRRA precludes RRG participation in state guaranty funds. |
Why the guaranty-fund point matters
Traditional admitted insurers may participate in state guaranty associations that can provide limited protection when a member insurer becomes insolvent, subject to state law. NAIC guidance states that RRGs are specifically precluded by the LRRA from participating in state guaranty funds. Prospective members should understand that difference when evaluating financial strength and governance.
RRG vs. captive insurer
An RRG can be formed under a state’s captive or traditional insurance laws, but it has a specific federal multistate framework under the LRRA. A single-parent captive usually insures risks of its parent and affiliates, whereas an RRG is designed around a group of members with similar liability exposures.
RRG vs. purchasing group
A purchasing group is not the same as an insurance company. It allows members with similar liability exposures to purchase insurance on a group basis from an insurer. An RRG, by contrast, is itself the risk-bearing insurance company owned by its members.
What a potential member should review
- The RRG’s domicile and regulator.
- Financial statements, capitalization and reinsurance program.
- Member eligibility and ownership obligations.
- Policy form, limits, deductibles and claims handling.
- Assessments, capital contributions or other member obligations.
- Whether the group’s liability coverage satisfies contractual or regulatory requirements.
- The absence of state guaranty-fund protection.
Frequently asked questions
Is an RRG licensed in every state where it writes business?
No. It is licensed in its domiciliary state and registers in other states under the LRRA framework.
Can anyone buy insurance from an RRG?
No. RRGs are built for members with similar or related liability exposures and membership requirements apply.
Does an RRG participate in state guaranty associations?
No. NAIC guidance states that the LRRA precludes RRG participation in state guaranty funds.
Is an RRG the same as self-insurance?
No. An RRG is an insurance company that assumes and spreads member liability risk, although it is an alternative risk-financing structure controlled by its members.
