What Is a Managing General Agent (MGA)?

A managing general agent is not simply a distributor that happens to underwrite. It is an entity authorised to bind coverage, administer policies, and in many cases handle claims on behalf of a capacity provider that has formally delegated those functions. The MGA does not carry the underlying insurance risk — the carrier or syndicate behind it does. But within the limits established by their binding authority agreement, the managing general agent acts with the operational autonomy of an underwriting entity.

The model has grown considerably over the past decade. MGAs now write over $200 billion in annual premiums globally, with concentration in specialist lines — construction and engineering, professional liability, cyber, marine cargo, warranty and indemnity, and parametric products. In the UK, one of the most developed MGA markets, the sector accounts for more than 10% of total general insurance premiums. In the United States, the surplus lines market has long depended on MGAs and managing general underwriters (MGUs) to place risk that standard admitted carriers cannot accommodate, with US MGA premium volume growing at approximately 10% annually according to McKinsey.

Understanding how managing general agents operate — the authority structures that underpin them, the financial mechanics that sustain them, and the operational infrastructure that differentiates high-performing businesses — matters for carriers evaluating delegated partners, for finance and operations teams within MGA businesses, and for the platforms that support the delegated authority ecosystem.

The delegated authority structure

At the foundation of every MGA relationship is a binding authority agreement — the contractual instrument through which a capacity provider formally delegates underwriting authority to the managing general agent. This agreement defines the scope of the delegation with precision: the classes of business the MGA may write, the geographic limits within which it may operate, the maximum risk size it may bind without referral, the policy terms and conditions it must apply, and the reporting timelines it must meet.

The binding authority agreement is not a general mandate. It is a constrained delegation. Any risk exceeding the defined parameters — in size, geography, or class — must be referred back to the capacity provider for approval before the MGA can bind coverage. The MGA operates with genuine underwriting discretion within those parameters; outside them, it acts as a conduit rather than a decision-maker.

The binding authority agreement also establishes the MGA's reporting obligations. Typically, this means submitting a bordereaux — a structured data file containing all risks bound, premiums collected, endorsements, and claims activity during the reporting period — to the capacity provider on a monthly or quarterly cycle. The bordereaux is the carrier's primary mechanism for oversight of its delegated book. Without accurate, timely bordereaux data, the carrier cannot understand what risks are on its book, whether claims reserves are adequate, or whether the MGA is operating within its delegated parameters.

The relationship sits within a regulatory framework that varies by jurisdiction. In the United Kingdom, MGAs that handle claims funds must be authorised by the Financial Conduct Authority. Lloyd's MGAs operating under Lloyd's binding authorities are subject to the Delegated Underwriting Committee's standards, which specify requirements for capacity management, data quality, and financial controls. In the United States, state-level surplus lines and admitted market frameworks each impose distinct requirements on managing general agents and the carriers that delegate authority to them.

What distinguishes the MGA model from other intermediary structures is the breadth and depth of the delegation. A coverholder may bind risks within a narrow, pre-agreed range. An MGA typically operates with broader authority, a more substantial policy administration infrastructure, and often a proprietary underwriting model that generates the specialist expertise the capacity provider is paying for.

What managing general agents actually do

The MGA's operational scope varies considerably by class of business and by the terms of its binding authority, but the core functions are consistent across the market.

Underwriting. The MGA evaluates individual risks, determines appropriate terms and pricing, and binds coverage within its delegated authority. This is the function that distinguishes the MGA from a pure distributor. The underwriting judgment resides within the MGA, not with the carrier's centralised underwriting team. In specialist lines, this is the primary value the MGA delivers to its capacity provider: deep class expertise that justifies the delegation and generates returns that a generalist carrier could not achieve independently.

Distribution and policy administration. MGAs typically operate through distribution networks — retail brokers, independent agents, affinity channels, or digital platforms — rather than distributing directly to end buyers. The MGA manages the full policy lifecycle: quotation, binding, endorsement, cancellation, and renewal. The carrier's operations team typically has no direct involvement in individual risk decisions; the MGA manages the book on its behalf.

Claims handling. Some MGAs hold claims-handling authority alongside their underwriting authority, managing claims from notification through to settlement either through an internal claims team or by appointing a third-party administrator. Others delegate claims handling back to the carrier or appoint a specialist TPA under a separate arrangement. Where claims authority is delegated, the MGA manages the claims fund: receiving capital from the carrier, maintaining claim account balances, and disbursing settlement payments.

The MGA business model depends on management fees (a percentage of gross written premium), profit commissions (a share of underwriting profit once losses are settled), and in some arrangements, claims management fees. The financial health of an MGA is therefore directly tied to both the volume and quality of the book it writes — and to how efficiently it manages the operational functions that generate those fees.

The financial mechanics: cash flows, bordereaux, and the claims fund

For finance and operations teams inside MGA businesses, the day-to-day financial mechanics are as consequential as the underwriting function. This is where the structural complexity of the managing general agent model becomes most visible — and where the difference between efficient and inefficient operations translates directly into capital, claimant experience, and carrier relationships.

Premium flows. When a policy is bound, the premium is collected — typically by the MGA or through its distribution network — and must be remitted to the capacity provider according to the terms of the binding authority agreement. The timing of this remittance is governed by the bordereaux cycle: premium collected during period X is remitted by the agreed date following period close. In high-volume MGA operations, managing the accuracy and timing of premium remittances is a material operational function, with discrepancies between bound premium and remitted amounts requiring reconciliation before each submission.

Cash calls and claims fund management. Where the MGA handles claims, it requires capital in its claims account to fund disbursements. That capital comes from the carrier through cash calls — formal requests for funds that trigger a capital transfer from the carrier to the MGA's claims account. In legacy operating models, this process follows a predictable cycle: the claims account balance falls below a threshold, the MGA issues a cash call, the carrier reviews and approves the request, and a bank transfer is initiated. Settlement occurs several days later. In the intervening period, the MGA may be unable to release settled claims payments — a delay that affects claimant experience and carrier relationships, and that recurs with every funding cycle.

Bordereaux reconciliation. The bordereaux is not simply a reporting exercise; it is a financial reconciliation. The claims bordereaux submitted to the carrier must match the disbursements made from the claims account. Discrepancies — misapplied payments, outstanding claims not yet reflected in the data file, timing differences between payment and reporting periods — require manual investigation and correction. The overhead of bordereaux reconciliation is substantial in high-volume portfolios, and errors create material differences between the carrier's view of claims liability and the MGA's operational records.

Capital efficiency. MGAs that lack real-time visibility into their claims account balances tend to hold more capital in reserve than their actual claims liabilities require. The rationale is straightforward: an underfunded account delays settlement, and that risk is managed by over-capitalising. When real-time account visibility is established, MGAs can manage their claims funds with greater precision — maintaining adequate balances without over-reservation, and providing carriers with a more accurate picture of claims liability at any point in the reporting cycle.

Regulatory obligations and carrier oversight

The regulatory obligations of a managing general agent extend in two directions simultaneously: toward the capacity provider that has delegated authority, and toward the regulatory bodies that govern insurance operations in each jurisdiction where the MGA writes business.

FCA authorisation (UK). MGAs that handle client money — including claims funds — must be authorised by the FCA and must hold those funds in compliance with the Client Assets Sourcebook (CASS). CASS specifies how claims funds must be segregated, where they can be held, and how they must be reconciled to the MGA's books. Non-compliance carries material regulatory risk. The FCA's Consumer Duty framework, in force since July 2023, places additional obligations on every firm in the distribution chain — including MGAs — to ensure good policyholder outcomes, of which timely and transparent claims settlement is a central component.

Lloyd's oversight. For MGAs operating under Lloyd's binding authorities, the Delegated Underwriting Committee conducts periodic audits of MGA operations, reviewing data quality, claims handling practices, and financial controls. Performance Standards govern bordereaux submissions, and MGAs that consistently submit inaccurate or late data risk having their binding authority curtailed or withdrawn.

Capacity provider oversight. Beyond formal regulatory requirements, carriers and syndicates typically conduct annual operational audits of their delegated partners — reviewing underwriting decisions, claims handling practices, and financial controls. A carrier with limited visibility into the real-time performance of its delegated book cannot adequately manage the risk it has accepted. The quality of the MGA's financial infrastructure — whether the carrier can access real-time claims fund data, whether reconciliation is accurate, whether claims are being settled within agreed timelines — is increasingly a factor in capacity decisions and binding authority renewals.

Why payment infrastructure defines MGA performance

The operational differentiators that separate high-performing MGAs from the rest are increasingly structural rather than underwriting-related. As the MGA market has matured and underwriting discipline has become more consistent, the variable that most visibly distinguishes top-quartile operations is the infrastructure underlying claims payment and fund management.

Claims settlement speed. An MGA with a fully funded, instantly accessible claims account can release settled claims within hours of approval. An MGA dependent on a periodic cash call cycle may take three to seven additional days to release the same payment — not because the claim is disputed, but because the capital is not yet in the account. That distinction is visible to claimants, to distribution partners, and to the carrier assessing whether its delegated partner is fulfilling its Consumer Duty obligations. In competitive lines, the MGA that settles faster creates a measurable advantage in distribution relationships.

Cash call elimination. Modern payment infrastructure enables MGAs to move from a reactive funding model to a proactive one. With real-time visibility into claims account balances, automated top-up triggers replenish accounts at defined thresholds — before a shortfall occurs. The carrier retains full visibility and control over the trigger conditions and transfer amounts. The MGA operates with uninterrupted capital availability. For high-volume claims operations, removing the cash call cycle from the process has been shown to eliminate days of operational latency while substantially reducing the administrative burden on both the MGA and the carrier's treasury team.

Reconciliation accuracy. Purpose-built insurance payment infrastructure reconciles each claims disbursement against the corresponding claim record in real time, as payments are initiated. The claims bordereaux submitted to the carrier matches the payment record exactly, because both are generated from the same underlying system. The manual reconciliation overhead that characterises legacy claims operations — the spreadsheet matching, the exception workflows, the period-end adjustments — is removed from the process entirely.

Multi-rail, multi-currency capability. MGAs operating in international or specialist lines manage claims payments across multiple currencies and payment systems. A claimant in Brazil requires a different payment rail than a claimant in Germany; both require a different approach than a UK domestic settlement via Faster Payments. Payment infrastructure with direct connectivity to multiple local payment networks — routing each payment through the optimal rail based on destination, speed, and cost — removes the operational complexity of cross-border claims disbursements from the MGA's day-to-day operations.

Vitesse provides the financial infrastructure that connects MGAs, carriers, and TPAs across this operational environment. Purpose-built for insurance rather than adapted from general banking or payments tools, the platform processes over $24 billion in insurance funds annually across 180 markets — enabling MGAs to manage claims accounts with real-time visibility, automated top-up capability, instant payment execution, and full reconciliation.

Frequently Asked Questions

What is a managing general agent (MGA)?

A managing general agent is an intermediary that has been formally authorised by a capacity provider — typically an insurance carrier or Lloyd's syndicate — to bind coverage, administer policies, and in many cases handle claims on the capacity provider's behalf. Unlike a standard broker, an MGA operates with delegated underwriting authority, making risk acceptance decisions independently within the parameters set by its binding authority agreement. The MGA does not carry the underlying insurance risk; it manages it on behalf of the capacity provider in exchange for management fees and profit commissions tied to the performance of the book it writes.

How does delegated authority work in insurance?

Delegated authority is established through a binding authority agreement, under which a capacity provider formally authorises an MGA to underwrite risks within defined limits. These limits specify the classes of business the MGA may write, the maximum risk size, the geographic scope, and the policy terms it must apply. Any risk exceeding those parameters must be referred back to the capacity provider before the MGA can bind coverage. The MGA's activity is monitored through regular bordereaux submissions — structured data files containing all bound risks, premiums, and claims activity — which give the carrier oversight of its delegated book.

What is a bordereaux in insurance?

A bordereaux is a structured data file submitted by an MGA to its capacity provider at regular intervals — typically monthly or quarterly. It contains a detailed record of all risks bound, premiums collected, endorsements, and claims activity during the reporting period. There are two primary types: a premium bordereaux (covering new business and renewals) and a claims bordereaux (covering notifications, reserves, and settlements). Accurate, timely bordereaux submission is a regulatory requirement for FCA-authorised MGAs and a contractual requirement in virtually all binding authority agreements. It also serves as the primary reconciliation mechanism between the MGA's operational records and the carrier's exposure view.

What is a cash call in insurance?

A cash call is a formal request from an MGA to its capacity provider for capital to fund its claims account. When the claims account balance falls below the level required to meet expected settlement obligations, the MGA requests additional funds from the carrier. In legacy operating models, the cash call process adds several days to the payment cycle: the request must be reviewed, approved, and settled via bank transfer before funds are available. Modern payment infrastructure can eliminate this reactive cycle by configuring automated top-up triggers that replenish accounts at pre-defined thresholds — before a shortfall occurs — maintaining continuous capital availability without the operational overhead of manual cash call management.

What does the FCA require of MGAs handling client money?

UK MGAs that handle client money — including claims funds received from capacity providers and premiums collected from policyholders — must be authorised by the FCA and must manage those funds in compliance with the Client Assets Sourcebook (CASS). CASS specifies how funds must be held (in segregated client accounts), where they can be deposited, and how they must be reconciled to the firm's books and records. The FCA's Consumer Duty framework, in force since July 2023, adds a parallel obligation: MGAs must demonstrate that their operations — including claims settlement processes — deliver good outcomes for policyholders throughout the distribution chain.

How is an MGA different from a Lloyd's syndicate?

A Lloyd's syndicate is an underwriting entity that assumes risk on its own capital base, provided by members (Names), corporate investors, or Lloyd's own central fund. An MGA, by contrast, does not carry capital against the risks it writes — it manages those risks on behalf of a capacity provider that holds the capital. An MGA can operate within the Lloyd's market, writing risks under a Lloyd's binding authority, or outside it, through non-Lloyd's carrier capacity. The syndicate is a risk carrier with its own balance sheet. The MGA is a delegated manager: its financial exposure is to its operational economics — fees and profit commissions — not to the insurance risk itself.

The structural case for infrastructure investment

The evolution of the MGA market has brought increasing scrutiny to the operational quality of delegated partners. Carriers that encountered claims reserve surprises, reconciliation failures, or regulatory concerns in delegated books a decade ago have invested substantially in improving oversight frameworks. The consequence for MGAs is a market in which capacity allocation decisions increasingly reflect operational quality alongside underwriting performance.

MGAs that have invested in modern financial infrastructure — real-time fund visibility, automated reconciliation, fast and accurate claims settlement — have found that the investment returns in carrier relationship quality, operational efficiency, and the ability to demonstrate regulatory alignment without significant administrative overhead. The capital freed from over-reserved claims accounts compounds as the fund visibility capability is applied across a wider portfolio. For MGAs operating in high-volume or international lines, the infrastructure choice also shapes how the business presents to prospective capacity providers — an MGA that can offer real-time claims account visibility, automated top-up management, and same-day settlement capability is presenting a materially different operational risk profile than one managing these functions through manual processes and periodic cash calls.
