What is a Managing General Agent (MGA)?

Anyone working in delegated authority will hear the term "MGA" used constantly - sometimes precisely, sometimes as a loose synonym for any third party that writes business on an insurer's behalf.

That looseness causes real problems. Getting the definition right matters, because the amount of authority an entity holds directly shapes the contractual terms, the reporting expectations, and the oversight burden the insurer carries.

This knowledge article gives a precise, standalone definition of a Managing General Agent, distinguishes it clearly from a standard coverholder and a broker, and explains why this distinction has practical consequences for data flow and oversight.

It is also important not to confuse a Managing General Agent (MGA) with a Managing Agent. Although the names are similar, they perform very different roles. A Managing Agent is a specific legal and regulatory role within the Lloyd’s market, responsible for managing one or more syndicates and the underwriting capacity they provide. An MGA, by contrast, is an organisation that has been granted delegated underwriting authority by an insurer or managing agent to write business on their behalf within agreed limits.

Definition

A Managing General Agent (MGA) is a type of coverholder that has been granted broader underwriting authority by an insurer - typically including the ability to price and underwrite risks within agreed guidelines, and sometimes to handle claims - under the terms of a binder agreement.

Every MGA is a coverholder. Not every coverholder is an MGA.

The insurer that delegates this authority remains ultimately responsible for the risks written under it, regardless of how much day-to-day decision-making has been handed over.

What authority does an MGA typically hold?

The exact authority an MGA holds is set out in its binder agreement, and this varies from arrangement to arrangement. However, MGAs typically hold a meaningfully broader mandate than a standard coverholder, which often includes:

• Underwriting risks within defined guidelines, without referring each one back to the insurer.
• Pricing policies according to agreed rating structures.
• Issuing policy documentation directly to brokers or policyholders.
• Managing renewals within their delegated authority.

Some MGAs are also delegated claims handling authority, allowing them to settle claims up to agreed limits. This is not automatic - it depends entirely on what the binder agreement specifies.

What an MGA cannot do is act outside the guidelines set by the insurer. Authority is delegated, not transferred. The insurer defines the boundaries, and the MGA operates within them.

MGA vs coverholder vs broker

These three terms get used interchangeably in casual market conversation, but they describe different roles.

Coverholder is the broader Lloyd's term for any entity authorised under a binder agreement to enter into contracts of insurance on behalf of an insurer. An MGA is one type of coverholder.

MGA specifically describes a coverholder with a wider scope of delegated authority - typically full underwriting and pricing discretion within guidelines, rather than a narrower administrative or distribution role.

Broker is a different function entirely. A broker acts on behalf of the client to place risk with insurers, and does not hold underwriting authority from the insurer in the way a coverholder or MGA does.

The practical significance of this distinction is that the label alone does not tell you the scope of authority in any given arrangement. Two organisations both described as "MGAs" in the market could have quite different levels of delegated authority, depending on what their individual binder agreements say.

Why the MGA structure matters for oversight and data flow

Because an MGA is making underwriting and often pricing decisions on the insurer's behalf, the insurer's ability to see what has actually been written - and on what terms - depends entirely on the quality and timeliness of reporting coming back from the MGA.

This is why bordereaux, audits and ongoing oversight arrangements exist: the insurer cannot exercise judgement over decisions it never sees in real time, so it relies on structured reporting to reconstruct an accurate picture of the business being written under its licence and capital.

The broader the authority delegated to an MGA, the more this oversight matters. An insurer that has handed over underwriting, pricing and claims authority is more exposed to the consequences of poor data flow than one that has delegated only narrow administrative tasks.

This is not a data processing detail - it is a direct consequence of what an MGA is. Wherever authority is delegated, responsibility is not. That gap has to be actively managed, and it starts with a precise understanding of exactly what has been delegated in the first place.

Example

A Lloyd's managing agent delegates underwriting authority for a specialist agricultural risk portfolio to an MGA based in South Africa.

The MGA underwrites and prices policies within agreed guidelines, issues policy documentation directly to local brokers, and submits monthly bordereaux back to the managing agent detailing premium, risk and claims activity.

The managing agent gains access to local underwriting expertise and market knowledge without opening a local office, while retaining ultimate responsibility for the risks - relying on the binder agreement's terms and monthly bordereaux to maintain appropriate oversight.

FAQs

• Is an MGA the same as a coverholder?

  Not exactly. An MGA is a specific type of coverholder. "Coverholder" is the broader Lloyd's term for any entity authorised to enter into contracts of insurance under a binder agreement, while an MGA typically holds a wider scope of authority, including underwriting and pricing decisions.

• Can an MGA handle claims as well as underwriting?

  Only if its binder agreement specifically grants that authority. Claims handling authority is not automatic simply because an entity is described as an MGA - it depends entirely on the terms agreed with the insurer.

• Who is ultimately responsible for risks written by an MGA?

  The delegating insurer remains ultimately responsible and accountable for risks written under an MGA's authority. This is why ongoing oversight, audits and accurate reporting arrangements remain essential, regardless of how much authority has been delegated.
