In December 2023, an email from Captive International promoted a medical stop-loss captive white paper. An accessible MSL Captives paper by Phillip Giles and Steven McFarland explains such structures, but the retrieved document is undated and could not be confirmed as the exact edition announced. It provides technical background for examining retained risk, collateral and exit obligations, rather than evidence of a new release or guaranteed employer savings.

Establish the exposure being accepted

Before joining a medical stop-loss captive, an employer should obtain a description of where claims risk sits. The proposal needs to distinguish the employer’s retained layer, any shared captive exposure and the protection supplied by an external insurer. Illustrations should show what happens under adverse experience, not only under the assumptions used to estimate an attractive outcome. The governing documents and contracts should support that description.

The employer should ask who can change the terms and how those changes will be communicated. A diagram of the initial arrangement may conceal decisions that occur at renewal or when membership changes. Management needs to understand the relevant authority and the consequences for its own obligations. A clear description makes it possible to compare the captive proposition with alternatives on a consistent basis.

Examine funding and collateral

A financial comparison should include the funds committed to the arrangement and the conditions governing their release. The timing matters: a projected favourable result does not necessarily make cash available when the employer expects it. Management should ask which amounts are at risk, which support potential obligations and what evidence is needed before they can be returned. The answer should come from the terms applicable to the proposed participation.

An employer should also test adverse scenarios. These need to explain the consequences of unexpectedly high claims and any additional funding obligation the arrangement may create. The assumptions should be reviewed by appropriate specialists rather than inferred from a marketing illustration. A useful comparison makes the downside and timing understandable to the people approving participation, including those who do not work with insurance structures routinely.

Understand the shared arrangement

Where participants share exposure, the employer should ask how membership and underwriting decisions affect the pool. It needs an explanation of who sets the criteria, how information is assessed and what happens when a participant’s experience changes. These questions should be answered without assuming that every other member has the same workforce or risk characteristics as the employer considering entry.

Reporting needs to show the experience relevant to the employer’s obligations. A favourable aggregate measure can coexist with an unfavourable outcome for a particular participant. Management should understand the calculation basis and the arrangements for resolving disputed information. The review should connect claims assumptions to the financial result, with limits on what can be concluded from an early period of experience.

Read the exit provisions at entry

Leaving the arrangement should be examined before joining it. The employer needs to know which obligations can survive withdrawal, who manages outstanding matters and what conditions affect collateral or other committed funds. A quotation for the next year may be insufficient to answer those questions. The relevant agreements should be assessed by advisers who understand both the insurance structure and the employer’s contractual position.

Service continuity also deserves consideration. Management should establish how information, claims administration and employee communications would be handled if the funding arrangement changes. The employee’s experience depends on those processes, even where the captive itself operates behind the employer’s medical programme. A financial exit plan and an operational transition plan should therefore be considered together, with accountable parties identified for the required work.

Match governance to the decision

The captive board should understand the assumptions supporting retained exposure and the information needed to monitor it. An INED can challenge the treatment of adverse scenarios, conflicts and obligations after a member exits. That role requires access to relevant evidence and a clear distinction between board oversight and the work of underwriting, actuarial and service specialists.

This editor recommends a decision record covering the risk layers, funding commitments, adverse scenarios and exit terms before participation is approved. The historical paper can help organise the questions, but the current contractual documents must provide the answers. Claims about savings should remain conditional on the assumptions and experience that support them. A well-understood downside is part of a sound employer decision, alongside the potential advantages of the structure.
