Captive restructuring and run-off tools

Greg Lang (pictured), founder of the Reinsurance and Insurance Network (RAIN), looks at four tools that captives can use in the period coming up to renewals.

Third-quarter captive conversations often change from growth plans to concerns of loss development and a need for collateral.  These conversations often precipitate reinsurance discussion and positioning for renewal. 

Commutation, novation, loss portfolio transfer (LPT), and adverse development cover (ADC) are four tools captive owners can deploy to close out, restructure or reassign liabilities. Each tool is designed for a specific purpose and chosen for a different reason. In the context of prudent risk management, captive owners often have strategic or capital reasons to restructure rather than let a contract expire.

Commutation

A commutation is a settlement agreement between a cedant/captive and its reinsurer.  It discharges all obligations under the reinsurance contract. This includes reserves, IBNR and any closed claims that may reopen. In exchange for a cash payment from the reinsurer, the reinsurer’s future obligations are extinguished and the contract is terminated. Commutation can apply to an entire contract or specific years or losses.

Reasons for commutation

• Reinsurers can sometimes have solvency issues. Commutations can convert an uncertain claim recovery into a certainty of cash today. Claim disputes and disagreements also lead to commutation. No one wants an ongoing relationship that can be costly or contentious.

• Removing a reinsurance recoverable can simplify the balance sheet, improve financial ratios and free up collateral tied to reinsurance.

• Provide administrative efficiency eliminating ongoing claims handling, reporting, audit and collateral-management costs on long-tail or legacy business.

Novation

The substitution of one party to a contract for another, such that the original party is fully released and the new party steps in with the same rights and obligations of the original contract. Novations are often completed through an assumption agreement, replacing the original insurer or reinsurer with a new one as the direct counterparty to the policyholder or cedant. Because it extinguishes the original party's obligations entirely, novation generally requires the consent of the remaining party (e.g., the policyholder(s), or the retrocedent/reinsured), which distinguishes it from an LPT or commutation.

Reasons for novation

• Provides the most complete transfer: original insurer/reinsurer has no residual liability or credit exposure to the transferred book.

• Obligations move fully off the original balance sheet (subject to consent and regulatory approval), offering cleaner statutory accounting and capital treatment than arrangements that leave indemnity risk in place.

• When a programme's fronting carrier or reinsurer changes. Novating existing policies or treaties to the new carrier/reinsurer avoids running two overlapping risk-bearing structures during a transition.

Retroactive reinsurance

This broadly covers any contract that indemnifies against liabilities tied to past insurable events.  Reinsurance structures can be customised and combined in several ways. Retroactive reinsurance does not cover new or future risks. The captive or ceding company pays a premium to an assuming reinsurer to take over financial responsibility for existing, open and IBNR claims. Under regulatory and statutory accounting, retroactive reinsurance must be accounted for retroactively, rather than prospectively. We will get into that more in a minute.  There are two major types of retroactive reinsurance: lost portfolio transfers (LPTs) and adverse development covers (ADCs). Let’s look at both.

Loss portfolio transfer (LPT)

A loss portfolio transfer is a reinsurance contract where the insurer or captive cedes losses (open claims and IBNR) for a defined book to a reinsurer in exchange for a premium reflecting a discounted present value of future payments. Unlike commutation, an LPT is a transfer of liability into a new reinsurance arrangement. The new reinsurer assumes responsibility for the transferred claims. Claims handling and associated cost usually transfer to the reinsurer as well.

Reasons for an LPT

• LPTs move incurred and unreported reserves off the balance sheet, improving a captive’s capital/surplus position. This will occur only if the premium paid is less than the carried reserve. This often is not the case. It is the biggest reason many LPTs are never consummated as buyer and seller cannot agree on a reserve figure or its future development.  

• Removing legacy reserves frees up capital. Collateral can be redeployed to current underwriting or other strategic use. This is a common driver for captives with long-tail liabilities such as workers’ compensation and general liability. LPTs can also free up capital for profitable programmes which are growing quickly.  

• Free up management’s time disproportionately consumed by discontinued operations relative to new business.

• Clean up legacy liabilities ahead of a sale, merger, redomestication, or restructuring, making the remaining entity easier to value.

Adverse development cover (ADC)

This is another form of retroactive reinsurance. It protects cedants against unexpected increases in open and IBNR claims. Like an LPT, ADCs cover historical liabilities from past underwriting years. What differentiates them is they only start paying after paid losses exceed an agreed upon attachment point. Most ADCs are caped. The reinsurer stops paying once the reinsurance reaches the maximum agreed coverage limit. If the cap is reached, liabilities over the cap again become the responsibility of the captive or ADC purchaser  

Pricing and picking an attachment point requires balancing current reserve confidence against the ADC premium cost. Actuarial projections are used to pinpoint where the captive’s reserves might fall and price the risk using time-value-of-money simulations.

Reasons for an ADC

• Like an LPT, caping legacy reserves frees up capital.  Collateral can be redeployed to current underwriting or other strategic use. Unlike traditional LPTs, an ADC’s risk exposure is capped.  Purchasers need to be aware that risk might return when the limit purchased is exhausted. 

Retroactive accounting and pricing

Retroactive reinsurance is evaluated differently from traditional reinsurance. The focus is on the timing of cash flows, P&L recognition and actuarial loss modelling. I am neither an actuary nor a CPA, so I am not trying to offer any advice here.  These are just some basics every prospective purchaser should understand. 

The accounting treatment of retroactive coverage treats past and existing liabilities as a financing or deposit arrangement rather than risk transfer. Cash flows are often recognised as deposits rather than immediate underwriting income. For an LPT, if the amount paid to the reinsurer is less than the current reserves, a financial gain is recognised. Under US GAAP and statutory accounting (SAP), this gain is typically deferred and amortised over the settlement period. For an ADC, any net gain to surplus is usually restricted until the actual recovery exceeds the premium paid.

The pricing of adverse development coverage depends heavily on where coverage attaches relative to current reserves. Pricing can be "in-the-money", where the premium is less than the reserves or "out-of-the-money" where the premiums paid are more than the carried reserve. The aggregate limit is also important. If the limit provided is small the transaction might not qualify for true risk transfer. 

For LPTs, payouts on long-tail casualty liabilities typically happen years into the future. Pricing models should discount projected cash flows and factor in investment income on the upfront premium. This is known as pricing for the time value of money.

Pricing models will also account for social inflation, legal environment changes and confidence variance percentages such as 60th or 80th percentile outcomes to charge a margin over the expected mean loss. 

The players – deal volume and size  

No single publication tracks the number of commutations, novations, LPTs and ADCs completed each year. PwC’s Global Insurance Run-off Survey counts publicly disclosed £legacy” transactions as a single category. They identified 31 deals in 2023, 33 in 2024 and 42 in 2025. Activity is most prevalent in the 4th quarter. Commutations are mostly absent from public data. They are private settlements without disclosure requirements. 

Captives sit on both sides of LPTs, as both cedants of legacy reserves and as named counterparties in deals done directly with a legacy acquirer. Two of the largest-disclosed LPTs in 2025-26 involved rideshare company captives: RiverStone International assumed $1.2 billion of commercial auto liability reserves from Pacific Valley Insurance Company, Lyft’s wholly owned captive, effective January 1, 2025 and signed a second LPT with Pacific Valley effective July 1, 2026. James River Group has an ongoing commercial auto LPT with Aleka Insurance, a captive affiliate of Uber's Rasier LLC, with cumulative reserves ceded of $451.4 million as of March 31, 2026. 

The supply side of the LPT market is concentrated among a few specialists. Six firms, Enstar, RiverStone International, Premia Holdings, Compre Group, Marco Capital (via Marco Re), and DARAG, account for more than half of global non-life run-off transactions.  RiverStone and Enstar are the largest and most established. Swiss Re (through its corporate solutions unit) and National Indemnity Company (Berkshire Hathaway) are also active, particularly on very large adverse development and retroactive covers. Randall & Quilter (R&Q) was historically known for pursuing smaller, niche legacy and captive transactions before its book was broken up and sold to Onex, Brickell, and Marco Capital in 2023-24.

None of the major acquirers publishes a minimum deal size. Appetite varies by firm and by how much actuarial/claims complexity a transaction carries. PwC’s 2025 review found that roughly 40% of all publicly disclosed non-life run-off deals were sub-$50 million in liabilities. I have personally been involved in transactions with reserves in the single-digit millions. One was for a single claim. That said, the largest, most established acquirers tend to gravitate toward transactions that justify deal costs. Very small captives are often better served by boutique or regional legacy specialists, or by bundling several years or lines into a single transaction to reach an economically viable size.

Conclusion 

Commutations terminate an existing reinsurance obligation for a final cash settlement. Loss portfolio transfers cede existing loss reserves into a new reinsurance arrangement, for balance sheet and capital relief. Underlying policies remain untouched. 

Adverse development, as the name implies, covers protection against adverse development without the necessity of transferring reserves off balance sheet. 

Novations substitute one risk-bearing party for another while requiring consent. They are the tool of choice for a complete and permanent transfer of a book of business. In programme and captive business, the choice of which tool to use depends on whether the goal is to end a relationship, (commutation), offloading a reserve (LPT), offloading a reserve drag while holding on to reserves (ADC), or to fully replace a carrier, captive or reinsurer in an ongoing programme (novation). It’s good to remember, there is a tool for that.
