Claim Denial Rates by Line of Business (2026)
UK motor rejects about 1% of claims. US homeowners closes 31% without payment. The gap is mostly definitional, not behavioural.
Policyholders may own the insurer. Shareholders may own it. Or an underwriting team builds the product while somebody else carries every pound of the risk.
Who owns an insurance business - and whose capital pays the claims?
The answers can be surprisingly different. Policyholders may own the insurer. Shareholders may own it. An entrepreneurial underwriting team may build the product and manage distribution while a separate carrier issues the policy and reinsurers take much of the economic risk.
Understanding these arrangements matters when launching a product, selecting a capacity partner or evaluating an acquisition. It also makes insurance ownership statistics easier to interpret.
The essential distinction is that mutual and stock describe insurer ownership; MGA describes an operating role. A mutual or stock insurer can provide capacity to an MGA. The MGA itself can have founders, a broker, an insurer or private investors as shareholders.
These structures can sit together in the same insurance programme.
| Statistic | Figure | Scope and interpretation |

| Mutual and cooperative insurance premium income | $1.61 trillion | Global 2024 business, reported by ICMIF in July 2026 |
| Mutual and cooperative insurance market share | 26.1% | Share of worldwide insurance premiums in ICMIF’s 2024 dataset |
| Breadth of ICMIF’s latest market research | More than 4,700 insurers across 80 countries and territories | Research coverage, rather than the membership count of one association |
| U.S. MGA premium volume | Approximately $128 billion | Conning’s estimate for 2025; premium handled, not MGA revenue or equity value |
| PE-owned U.S. insurers identified by the NAIC | 137 at year-end 2024 | A company count within the NAIC’s identified population |
| Active Vermont captives | 707 at year-end 2025 | One domicile, which licensed 51 new captives during the year |

These figures belong beside one another as context, not as slices of the same market-share chart. MGA business is also written on insurers’ balance sheets. Captives can have a stock or another permitted legal form. Private equity describes the investor behind a business.
| Structure or role | Who owns or controls it? | Where insured risk sits | When it can make sense |
|---|---|---|---|
| Stock insurer | Shareholders, privately or publicly held | The insurer’s balance sheet, with reinsurance where arranged | Building a carrier with access to equity investors and direct control over underwriting capacity |
| Mutual insurer | Policyholder members under its governing arrangements | The insurer’s balance sheet, with reinsurance where arranged | Serving a durable membership or customer community through a member-owned carrier |
| MGA / MGU | Founders, employees, brokers, insurers or financial investors | Normally with the carrier and its reinsurers; any MGA risk participation needs a separate arrangement | Combining specialist underwriting and distribution with third-party capacity |
| Reciprocal exchange | Subscribers participate in the exchange; an attorney-in-fact administers it | The exchange’s insurance arrangements and surplus, supported by reinsurance where applicable | Combining subscriber participation with a separately organised management function |
| Captive insurer | Typically the insured parent, group or participating organisations | The captive retains its agreed risks and may buy reinsurance | Financing selected risks of the owners or participating businesses |
Definitions draw on the NAIC insurance glossary, NAIC captive insurance overview, NAIC’s explanation of organisational forms and Lloyd’s coverholder guidance. The final column gives practical use cases, rather than a universal ranking.
The boundaries are worth keeping in mind. A captive may be incorporated as a stock company. A mutual group may own stock subsidiaries. A carrier-owned MGA remains an MGA because of the work it is authorised to perform.
A stock insurance company is owned by shareholders. It can be listed on a public exchange, privately held, or a subsidiary of a larger group. A customer buying a policy does not acquire an ownership stake simply through that purchase. NAIC insurance glossary
The structure provides a familiar route for investors to fund the business through equity. It can also support acquisitions and changes of control, subject to the relevant insurance approvals.
For a team building a full carrier, the attraction is control: underwriting appetite, policy terms, claims strategy and balance-sheet deployment can sit within the same organisation.
That control comes with a larger undertaking. The carrier needs the capital, reserving, investment management, governance and operational resources to support the risks it accepts. Raising money for software and distribution is only part of the funding requirement.
When does it fit? A stock carrier can make sense where the business wants to own insurance risk over time, has access to patient capital and can support the regulatory and actuarial infrastructure involved.
Shareholder ownership alone does not tell us whether that carrier prioritises short-term earnings or long-term resilience. Its incentives depend on the owners, board, compensation arrangements and business plan.
A mutual insurance company is owned by its policyholders, with ownership interests that do not take the form of ordinary shares. Demutualisation changes that ownership form into a stock company. IRS explanation of mutual ownership and demutualisation
The economic proposition is to operate the insurer for its members over time. Depending on the company and contract, value can emerge through service, product terms, retained financial strength or eligible policyholder distributions. A distribution should not be assumed simply because the insurer is mutual.
ICMIF’s latest figures put mutual and cooperative insurers at just over one-quarter of global premiums. The 26.1% share relates to 2024, although the report was published in 2026. ICMIF’s latest global market-share findings
This is a broad mutual and cooperative sector measure. It does not justify treating the remaining 73.9% as a verified global stock-insurer share, nor should it be applied to every country or business line.
When does the model fit? It can suit a membership with enduring protection needs and a willingness to build financial strength collectively. Professional communities, regional customer bases and established policyholder groups are potential examples.
The trade-off is access to capital. A mutual cannot issue ordinary ownership shares in the way a stock company can, although it may have other funding options. In the U.S., surplus notes can qualify as statutory capital; their issuance and repayment require regulatory approval. NAIC surplus notes overview
Member ownership still requires commercial discipline. Underpricing and weak claims management can erode a mutual’s surplus just as they can damage a stock carrier’s capital.
A managing general agent performs functions delegated by an insurer, commonly including risk selection, pricing within agreed parameters and binding cover. The scope depends on the contract and applicable rules. Claims authority may be delegated separately or retained by the carrier.
At Lloyd’s, a coverholder’s binding authority sets out the functions it can perform on behalf of the relevant syndicate. Lloyd’s explanation of binding authorities
An MGA can therefore look like an insurer to the customer while the insurance contract is issued by another entity. Its brand, underwriting process and service experience do not by themselves make it the risk carrier.
That separation is commercially useful. A specialist team can develop a cyber, professional liability or niche property programme without first establishing its own insurance balance sheet.
When does it fit? The MGA model is attractive when the team’s strongest assets are underwriting knowledge, distribution access and an ability to manage a defined portfolio - and when suitable capacity partners are willing to support it.
Conning estimates U.S. MGA premium volume at approximately $128 billion in 2025, including business beyond what statutory filings capture. Its broader estimate includes Lloyd’s business and other premium not fully visible in those filings. Conning’s 2026 MGA market study
One fifth of US MGA premium runs through a fronting carrier
Split of Conning’s $128 billion 2025 estimate. The two amounts are our calculation from its reported 20% share.
Conning, 2026 MGA market study
An MGA generally earns commissions and fees, potentially including profit-related remuneration. Premium flowing through the programme should not be mistaken for the MGA’s own revenue, capital or valuation.
Nor is capacity permanent. Appetite, pricing requirements and contract terms can change as experience develops.
As AM Best industry research analyst Helen Andersen puts it:
“The maturing MGA market will need greater discipline in building portfolios”
AM Best’s June 2026 assessment of the MGA market
For an MGA, the ability to provide credible exposure, premium and claims data can be as consequential as winning new distribution.
The phrase “MGA capital” can describe several different funding needs.
| Funding layer | What the money supports | Typical question |
|---|---|---|
| Operating-company equity | Staff, technology, distribution and working capital | Who owns the MGA and funds its development? |
| Carrier capital | The insurer’s obligations and regulatory requirements | Which licensed insurer issues the policy? |
| Reinsurance capacity | Contractually assumed portions or layers of insured risk | How is risk shared beyond the issuing insurer? |
| Additional risk participation | A defined participation through a captive, reinsurer or other permitted arrangement | Does the MGA group or its investors also retain insurance risk? |
An investor can own equity in the MGA without supplying capital to the insurer. Conversely, a reinsurer can provide capacity without owning the MGA.
This explains why two programmes with similar premium volume may have very different economics. One may earn relatively stable administration and underwriting fees. Another may also retain a portion of underwriting results through a separate risk-bearing arrangement.
A fronting insurer issues policies and reinsures all or a substantial share of the risk. Under ordinary indemnity reinsurance, the issuing insurer remains responsible to the policyholder even if its reinsurer fails to pay. That leaves meaningful oversight, counterparty and liquidity responsibilities with the fronting insurer. NAIC 2026 Accounting Practices and Procedures Manual, reinsurance definitions
Conning estimates that approximately 20% of U.S. MGA premium was supported by fronting relationships in 2025. Conning’s 2026 findings
Consider a simplified example: an MGA designs a property programme; a carrier issues the policies; a reinsurer assumes an agreed share of losses. The MGA’s shareholder funds the underwriting team. The carrier and reinsurer supply the insurance capacity.
If that programme writes $100 million of premium, it has not created three separate $100 million markets. The same business appears at different points in the chain.
Private equity is an ownership and financing source, rather than a separate insurance licence or underwriting function.
The NAIC identified 137 PE-owned U.S. insurers at year-end 2024, rising to 139 by June 2025. Those counts concern insurance companies; they are not counts of PE-backed MGAs or brokers. NAIC private equity overview
Across the wider MGA market, outside investment may fund acquisitions, specialist hiring or new distribution. The useful questions are specific: where is debt held, what cash flows service it, how dependent is revenue on a small number of capacity agreements, and what happens when ownership changes?
For a carrier, the assessment also needs to follow the regulated balance sheet, asset management arrangements and support available under stress.
The investor label is a starting point for due diligence. It is not a complete description of the business’s risk.
In a reciprocal, subscribers exchange insurance through an attorney-in-fact that administers the arrangement. The exchange and its management business must be understood separately. NAIC explanation of reciprocal structures
A reciprocal can suit an arrangement seeking subscriber participation alongside professional management. Its design needs particular attention to fees, governance, surplus and any subscriber obligations under the contract.
These are active supervisory issues: the NAIC’s 2026 Reciprocal Exchanges Working Group is working on model-law changes addressing attorney-in-fact fees. Proposed model changes should not be confused with laws already enacted in each state. NAIC Reciprocal Exchanges Working Group
A captive is formed to insure risks associated with its owners or participating organisations. The category includes different arrangements, such as single-parent, group and protected-cell structures. NAIC captive insurance overview
Vermont’s 707 active captives at the end of 2025 illustrate the scale possible in one established domicile. That is not a worldwide captive count. Vermont’s captive industry results
When does it fit? A captive can make sense when an organisation has credible loss data, the resources to retain selected risks and a clear reason to take greater control of its risk financing.
It still needs funding and administration. Retaining a loss through a captive moves the financial responsibility; it does not remove the underlying exposure.
Start with the business objective.
These are potential fits. Portfolio quality, governance, funding and execution determine whether the structure works in practice.
When reviewing insurance company ownership structure statistics, ask whether the data classifies the legal entity, its ultimate parent, its operating role or its source of capital. Without that distinction, a market-share comparison can look precise while answering the wrong question.
Useful insurance ownership statistics preserve those distinctions and connect them to the decision being made.
Each arrangement creates different information needs. A mutual needs reliable member records. A carrier needs policy, claims and financial information that supports its obligations. An MGA needs authority controls, partner reporting and clear allocation of commissions and claims responsibilities.
Openkoda supports configurable insurance applications for carriers, MGAs and other insurance businesses. The aim should be to reflect the actual relationships between owners, underwriters, capacity providers and administrators in day-to-day workflows and reporting.

UK motor rejects about 1% of claims. US homeowners closes 31% without payment. The gap is mostly definitional, not behavioural.

EEA insurers wrote about 1.6 trillion euros in 2025. The harder question is which countries the number actually covers.

The US industry ran a 25.8% expense ratio in 2025. Lloyd's ran 35.6% and made more money. A benchmark is only useful once you know what it is measuring.
