Fronting arrangements and fronting carriers: how they work

Fronting means a licensed, rated insurer issues the policy and then passes some or nearly all of the risk to someone else, usually a captive or a group of reinsurers. The buyer, the state and the contract counterparty see a policy from an acceptable carrier. The risk, and most of the premium, sit with the party behind the front. The fronting carrier earns a fee and takes on credit risk: if the party behind it does not pay, the front still owes the policyholder.

Fronting is used in two places that look similar and work differently. One is captive programs, where the owner's captive needs a licensed carrier to issue the paper. The other is program business, where a managing general agent (MGA) designs and sells a book and needs rated capacity. This guide covers both, with the emphasis on captives.

Why a captive needs a front

A captive is licensed in one domicile, and most captives are not admitted to write business in every state where their owners operate. That limits what the owner can show to anyone who demands "insurance." Three common reasons for a front:

• Statutory filings. Workers' compensation, auto liability and similar coverages are tied to state financial responsibility laws that expect a licensed insurer or a state-approved self-insurer. Interstate motor carriers need an insurer or surety to file proof of coverage with the Federal Motor Carrier Safety Administration. The MCS-90 endorsement, the MCS-82 surety bond and FMCSA self-insurance authorization are the options under 49 CFR 387.7(d). See FMCSA insurance requirements and filings for motor carriers.
• Contract requirements. Leases, customer contracts and loan agreements frequently ask for a certificate from a carrier with a minimum AM Best rating (A- is a common floor). A captive may be too new or too small to be rated.
• Local licensing. The front brings state licenses, forms, rate filings, claims and premium tax remittance the captive does not have to build itself.

Captive.com, the IRMI-run reference site, describes the core idea as using an admitted insurer to issue a policy for a self-insured organization or captive without an intent to transfer the risk. In a captive program the front retains a small slice or none, and cedes the rest to the captive by reinsurance agreement.

How the paper and the money flow

1. The business buys a policy from the fronting carrier, pays premium to it, and receives the policy, forms and certificates in the front's name.
2. The front keeps its fee and ceding costs (premium tax, any filing costs) and cedes the rest of the premium to the captive.
3. Claims are reported to the front or to a third-party administrator named in the program. The front pays the policyholder.
4. The front collects from the captive, usually by drawing on collateral the captive posted at the start.
5. Losses above the captive's layer go to excess or reinsurance markets, sometimes through the front and sometimes bought by the captive directly.

The front is the cedent in its reinsurance with the captive. The detailed terms live in the reinsurance agreement and a separate service agreement, not in the policy you hold.

What it costs

Two costs matter: the fee and the collateral.

The fee. Captive.com gives a range of roughly 6 to 10 percent of gross written premium as an illustration, noting that it depends on the services the front provides and interest rates. Treat that as a starting point from a trade source, not a quote. What you are buying changes the number: claims handling, premium audit, loss control, regulatory filings, and how much risk the front keeps.

The collateral. The front faces the credit risk of the captive, so it asks for security. Captive.com says the front's actuaries typically ask for 125 to 150 percent of the projected loss fund, held as funds withheld by the front, a trust funded with the captive's securities, or a letter of credit. IRMI commentary by Michael Mead (2007) describes the method as collateralizing the "gap" between the maximum probable loss and the captive's capital, surplus and earned premium, and warns that the gap, and so the collateral, can grow over time. Letters of credit use bank capacity; a trust usually costs less and earns investment income. Negotiate this early, because it is the term that most often decides whether a captive pencils out. See Is a captive right for your business? A feasibility checklist.

A hypothetical illustration

Say a trucking company's captive takes the first $500,000 of each liability claim and the actuary projects a loss fund of $650,000 for the year, written on $1 million of premium through a front. At 6 to 10 percent, the fee is $60,000 to $100,000. Collateral at 125 to 150 percent of the loss fund is $812,500 to $975,000. The numbers are invented to show the arithmetic, not market prices. If the company's bank would count a $900,000 letter of credit against its credit line, the CFO has to decide whether that borrowing capacity is worth the captive's expected savings.

The risk the front takes

The front can look like a pass-through, but the policyholder's claim runs against the front. If the captive or reinsurer behind it does not pay, the front must still honor the policy, which means the front carries the counterparty credit risk.

That is why ratings agencies and regulators watch the practice. AM Best's special report, "Front" and Center: A Review of the Property/Casualty Fronting Market, published in September 2026, says upwards of $30 billion of premium flowed through fronting arrangements in 2025 and that specialist fronting direct written premium grew from about $1.8 billion in 2015 to nearly $20 billion, with double-digit growth every year through 2025 (as reported by Insurance Business). The same coverage says AM Best follows 16 rated organizations whose primary operation is fronting, and that reinsurers are pushing fronts to keep more risk of their own, especially in specialized MGA programs. AM Best also flagged offshore entities, unauthorized captives and unrated carriers that use fronting to reach business their own ratings would not allow.

The 2023 collapse of the insurtech Vesttoo made the collateral risk concrete. Letters of credit that backed reinsurance with several fronting carriers were alleged to be fraudulent, and AM Best said it was reviewing its rated fronting carriers and other insurers with material reinsurance credit risk. Clear Blue, one of them, took a write-down on reinsurance recoverables and raised new capital before AM Best affirmed its rating in November 2023; its profile has the details (see Clear Blue Insurance Group). The lesson for a captive owner is that the front's security depends on the quality of the collateral, not just the amount.

What the policyholder should check

If you are a captive owner or a buyer insured by a fronted program:

• Who is the issuing company? The declarations page names it. Look up its AM Best rating and financial size category; see AM Best ratings explained for business buyers.
• Admitted or surplus lines? An admitted front brings state guaranty fund protection if the front fails. A surplus lines front generally does not. See admitted vs non-admitted insurers: what the difference means and what happens when an insurer fails: guaranty funds and business policies.
• Who handles claims? The front, a TPA or the captive. Ask who controls settlement and how a dispute is escalated.
• What happens if the program moves? Programs change fronts. Check whether your coverage, tail and claims history move with it, or whether you must re-underwrite at renewal.
• Does the certificate match the contract? Contract requirements often name carrier ratings and forms. A certificate from a front satisfies them; the captive behind it is invisible to the counterparty.

Questions for a front before you sign

1. What fee, and what does it include (claims, audit, filings, premium tax, loss control)?
2. How is the collateral amount calculated, and when is it re-measured and released?
3. What forms of collateral are accepted, and which banks?
4. How much risk does the front keep, and is it a pure front?
5. What are the termination terms, notice periods and run-off provisions, and who pays for run-off claims?
6. What reinsurance does the front buy for itself, and with which counterparties?
7. Can I use my own claims administrator or must I use theirs?

Who offers it

Several insurance groups run fronting units or are fronting specialists. Examples with their own profiles here are Markel (through State National), Clear Blue, Accelerant and Sutton National. Their inclusion is not a recommendation. Some are program-focused fronts that serve MGAs; others serve captives. Ask any candidate for its most recent AM Best rating letter and its fronting terms.

Key takeaways

• A front is a licensed carrier that issues the policy and cedes the risk to a captive or reinsurers; it earns a fee and takes the credit risk if the party behind it fails to pay.
• Captives use fronts to meet state filings, FMCSA proof of coverage, rating requirements in contracts and local licensing.
• Trade sources cite fees of about 6 to 10 percent of premium and collateral of 125 to 150 percent of the projected loss fund; both are negotiable and depend on the program.
• AM Best reported upwards of $30 billion of premium through fronting in 2025 and warned about unrated and offshore reinsurers; the 2023 Vesttoo episode showed that the quality of collateral matters as much as its size.
• The declarations page names the real issuer. Check its rating, whether it is admitted, and who controls claims.
