In U.S. marine cargo insurance, it is common for more than one insurer to underwrite a single policy. You may hear this subscription market called a market placement or a slip policy, where multiple insurers each take a percentage of the risk. While this arrangement spreads risk efficiently, it can also introduce confusion and friction when a loss occurs.

Knowing how that shared responsibility unfolds in a claim can save time—and headaches—when losses are significant. As slip arrangements become more common, driven by capacity fluctuations and other market conditions, it is increasingly important for cargo owners and policyholders to understand an area long familiar to brokers and marine underwriters; knowing how responsibility is divided, who calls the shots, and where the process can break down.
What Is a Slip or Market Cargo Policy?
A market cargo policy features multiple insurers underwriting a percentage of the same risk under a single policy structure; the insured contracts directly with multiple insurers. (This is not to be confused with reinsurance, which involves an insurer transferring their own risk behind the scenes without the insured’s involvement.)
In the U.S., this typically includes one lead underwriter, who is designated in the policy or binding documents to handle claims day-to-day. Some policies include a claims control or claims handling clause allowing this insurer (sometimes “claims agreement party”) to settle claims up to specified limits on behalf of the others.
The additional participating (following) underwriters are carriers that insure the remaining percentage(s) of the risk. Depending on the policy wording, they may agree to be bound by the lead’s decision or reserve rights to concur on larger or complex claims.
In the US, the extent to which following insurers are bound by a lead’s decision is primarily a matter of policy wording. If there is no explicit settlement-authority clause, participating underwriters may retain the right to approve settlements. This can result in delays when following insurers do not agree with the lead’s interpretation of the policy wording or require additional documentation before they will contribute their percentage of the loss.
How Claims with Multiple Insurers Typically Proceed in the U.S.
When a loss is reported, the claims process unfolds in stages:
Initial Coordination: The lead/handling insurer confirms coverage, assigns a loss adjuster and oversees the investigation. This includes preliminary verification of policy terms, reviewing the circumstances of loss, and determining whether the claim generally falls within the scope of the policy.
Investigation and Valuation: An independent claims adjuster investigates the loss to establish causation (i.e., who, what, where, when, and how), and quantum, the value of the loss. The adjuster’s role is to provide an impartial, technically sound analysis that includes evidence, inspection findings, salvage or repair information, and recommended settlement ranges.
Follower Involvement: If the policy grants settlement authority, the lead can settle within that authority without separate approvals. If no such authority exists, participating followers may review and concur on larger, complex, or unusual claims before settlement is offered
Broker Coordination: The broker keeps the train on the tracks, gathering documentation, relaying updates, and coordinating each carrier’s share of any settlement. The broker also ensures participating underwriters receive all relevant information and coordinates payments by each.
Payment Execution: Payments are typically funded by each market share directly via the coordination of the broker. Lloyd’s Central Settlement may be used where London market capacity is involved. This arrangement aims to balance speed (via a designated handler) with objectivity (honoring each carrier’s share and rights). As a result, final payment to the cargo owner depends not solely on the lead’s approval, but on the administrative processes of every participating carrier.
Resolution & Subrogation: The lead insurer may take on the task of managing the rights to recover from the responsible party, once payment has been completed. Some market policies contain a formal subrogation agreement which identifies each party, their roles and duties, along with the scope of subrogation, control and decision making.
The Adjuster’s Critical Role
An independent loss adjuster serves as the investigative and technical backbone of the claims process.
Every claim begins with a thorough investigation of the loss, usually through site visits, interviews and documentation reviews to understand liabilities, circumstances and underlying causes of the incident. The valuation phase follows where loss value is determined by examining invoices, contracts and shipping documentation in the context of policy terms and conditions.
Throughout the process, adjusters serve as a critical link between the insured and insurers, reporting their findings to the lead insurer. Once they align their insights with the specific terms, conditions and exclusions outlined in the policy, the adjuster often also assesses salvage strategies and positions the claim for subrogation pursuit.
Although an independent adjuster tracks the policy numbers, market shares and settling authority, it is important to note the adjuster does not negotiate separately with each participating underwriter. Instead, their findings provide the lead and reviewing followers with the information and analysis they need to reach resolution quickly and efficiently.
Common Friction Points and How to Avoid Them
While the lead-follower model is designed to streamline the claims process, several common issues can postpone resolution; for example, ambiguous settlement authority. If the policy wording does not clearly spell out what the lead can decide independently, even simple claims might require approval from each individual market. Making settlement authority language clear at policy inception will expedite the claims process.
Documentation quality is also critical. When files are well-organized and complete from the outset, claims move through a system much more efficiently. However, the process becomes more complex when dealing with multiple insurers, each operating with their own unique procedures, approval workflows, and timelines. Maintaining effective communication between the markets, broker and independent adjuster promotes alignment and supports efficient resolution.
Sometimes disputes arise over coverage or valuation. If authority is ambiguous and just one insurer disagrees with the lead’s determination, the process can come to a complete standstill. Clear, evidence-based evaluation in the adjuster’s report leaves less room for argument.
As with any business transaction, clear communication is key. All parties need to be well informed throughout all stages of the process. Silence leads to frustration and mistrust.
Why Subscription Markets Matter
As underwriting capacity in marine cargo lines continues to shift, subscription placements are becoming both more widespread and complicated. Cargo owners moving complex or high-value shipments increasingly find their coverage spread across multiple insurers.
Understanding how multi-insurer policies operate is no longer optional. How subscription markets work directly impacts how fast claims are resolved, when funds are received, and ultimately, whether operations can continue uninterrupted following a loss.
Conclusion: Clarity and Information are Key
For U.S. market cargo policies, one loss is touched by many parties. Multiple carriers share the risk but claims typically flow through one designated lead who manages all aspects. This system works best when everyone understands their role, the authority is clear, and the documentation is solid.
For policyholders and brokers navigating these programs, success comes down to a few basics: understand how the policy is structured, provide complete information as early as possible, and engage adjusters who clearly communicate technical loss details in straightforward terms and are trusted by all subscribing insurers. By keeping all stakeholders aligned with clear facts and transparent communication, we guide claims efficiently toward a timely resolution.
