Reinsurance is often arranged through specialist intermediaries rather than negotiated directly between the cedent and reinsurer. Calling every intermediary a “broker” can hide an important legal distinction. In the NAIC Reinsurance Intermediary Model Act, the intermediary-broker acts on the ceding side without acting as the reinsurer’s manager, while an intermediary-manager acts as an agent of the reinsurer with broader authority.
The model act is not itself a nationwide federal statute. States adopt and modify insurance laws. Still, Model #790 provides a useful framework for understanding why intermediaries can have licensing, contract, accounting and recordkeeping duties.
Broker vs. manager: the core distinction
| Role | Primary relationship | Typical authority |
|---|---|---|
| Reinsurance intermediary-broker (RB) | Acts in arranging reinsurance for a ceding insurer | Solicits, negotiates or places cessions/retrocessions without acting as the reinsurer’s manager |
| Reinsurance intermediary-manager (RM) | Acts as agent for a reinsurer | May bind or manage all or part of the reinsurer’s assumed reinsurance business, subject to statutory exceptions |
The difference is not simply job title. Authority matters. A firm that has underwriting or binding authority for the reinsurer can create a different regulatory profile than a broker that places a treaty for the cedent.
Why reinsurance intermediaries are regulated
Reinsurance transactions can move large premium balances and create material credit exposure between insurers. An intermediary may handle funds, transmit accounting information, document placements and influence which reinsurer assumes risk. Regulators therefore focus on licensing, fiduciary handling of money, written contracts, records and the insurer’s or reinsurer’s oversight of the intermediary.
NAIC’s broader reinsurance guidance notes that reinsurance may be negotiated directly or arranged through a third party such as a reinsurance broker or intermediary. The model act then supplies a more detailed regulatory structure.
Written agreements are central
A sophisticated reinsurance placement should not depend on informal expectations. Model-law frameworks require written contracts addressing the intermediary’s duties and the rights of the parties. Depending on the role, provisions can address authority, accounting, remittance of funds, records, underwriting standards, claims, reporting and termination.
This becomes especially important for an intermediary-manager because the manager can perform functions that sit close to the reinsurer’s own underwriting operations.
Money handling and fiduciary controls
Premiums, return premiums and claim-related funds passing through an intermediary create operational and credit risk. The model act contains controls around accounts, records and handling funds. A cedent or reinsurer should understand where money is held, who can withdraw it, when balances must be remitted and what reconciliation evidence is available.
Records and auditability
Reinsurance is document-intensive: treaty wording, endorsements, bordereaux, premium statements, claims notices and settlement records may span many years. Regulatory frameworks therefore emphasize record maintenance and access. Poor records can create problems long after placement, especially in long-tail liability lines where claims emerge years after the original underwriting period.
How intermediaries fit into the reinsurance chain
Start with our reinsurance fundamentals guide. A cedent can buy a broad treaty or a specific facultative placement, explained in Treaty vs. Facultative Reinsurance. The intermediary can help structure, market, document and service those placements. In proportional treaties, economics can also include acquisition-cost reimbursement and commissions, discussed in our ceding commission guide.
A practical placement example
A regional insurer wants catastrophe excess-of-loss protection. Its reinsurance broker prepares exposure information, approaches markets, negotiates terms and helps finalize placement. The broker does not automatically have authority to bind the reinsurer’s entire assumed portfolio. By contrast, a reinsurance intermediary-manager working for a reinsurer may be authorized under contract to underwrite or bind assumed business within defined guidelines. The regulatory controls reflect that broader authority.
Due-diligence questions for cedents and reinsurers
- Is the intermediary properly licensed where required?
- Is the firm acting as broker, manager or in another capacity for this transaction?
- Does the written agreement accurately describe authority and limits?
- Who controls premium and claim funds?
- How frequently are accounts reconciled and reported?
- What records are retained and how can the insurer or regulator access them?
- Are conflicts of interest and compensation disclosed and governed?
- What happens to records and funds after termination?
Why terminology matters in contract review
Terms such as broker, intermediary, MGA and manager are sometimes used loosely in market conversation. Regulatory definitions can be narrower. A contract reviewer should map the actual functions performed—soliciting, negotiating, binding, underwriting, claims authority, fund handling—rather than relying on a business card title.
State-law and operational checks before appointment or renewal
Because U.S. insurance regulation is primarily state based, a compliance team should not treat the NAIC model text as a substitute for the law in the states that matter to a transaction. Before appointing or renewing an intermediary relationship, identify the domiciles of the cedent and reinsurer, the states in which the intermediary is acting, the functions it will perform and whether it will hold funds, exercise binding authority or participate in claims handling. Those facts determine which licensing, contract and oversight questions need to be checked against the applicable statutes and regulator guidance.
A useful operational control is a written authority matrix that separates what the intermediary may do from what requires insurer or reinsurer approval. The matrix can cover quotation, binding, premium collection, return premium, claims settlement, commutation, retrocession placement and access to records. It should align with the executed agreement rather than a sales presentation or informal email. Periodic review is also important because personnel, authority limits, counterparties and state requirements can change while a reinsurance program remains in force.
This distinction is especially valuable during audits and disputes. If records show who had authority, where funds were held and which approvals were required, the parties can reconstruct the transaction more reliably than if they rely on job titles or market convention alone.
Frequently asked questions
Is a reinsurance intermediary-broker the same as a retail insurance broker?
No. The reinsurance intermediary operates in transactions between insurers or reinsurers rather than ordinary consumer policy sales.
Can a reinsurance intermediary-manager bind coverage?
The NAIC model definition contemplates a manager with authority to bind or manage assumed reinsurance business, subject to the contract and applicable law.
Are NAIC model laws automatically binding in every state?
No. States enact insurance law and can adopt, modify or decline model language.
Why does fund handling matter so much?
Large premium and claim balances can pass through intermediaries. Segregation, records and timely remittance reduce operational and credit risk.
