Traditional reinsurance is often purchased around a line of business and a defined loss layer. Structured reinsurance starts from a wider objective: reduce earnings volatility, support growth, release capital, protect a reserve development risk or manage the timing of losses over several years. The solution may combine proportional and non-proportional features, experience accounts, profit commissions or multi-year limits.
Complexity is justified only when the transaction transfers real insurance risk and produces an outcome that management can explain. Regulators, auditors, rating agencies and boards increasingly focus on whether capital relief is commensurate with the effective risk transfer. A structure that is economically unclear can create governance risk even if the documentation is technically complete.
The design process therefore has to connect actuarial scenarios, contractual cash flows, accounting treatment, solvency recognition and operational execution.
An insurer may need capacity to write more business, protection against an adverse loss ratio, support for a new portfolio, relief from legacy reserve uncertainty or a smoother pattern of results. These are different problems. A quota share may be appropriate for growth and capital support, while an aggregate stop loss may be better for annual volatility. A loss-portfolio transfer or adverse-development cover can address existing reserves.
The objective should be expressed in measurable terms: the losses to be transferred, the capital position to be protected, the time horizon and the maximum retained downside. This allows the parties to compare a structured solution with simpler alternatives and prevents features from being added without a clear purpose.

Solvency frameworks recognise reinsurance when the arrangement transfers risk effectively and the protection is legally enforceable. The amount of recognised benefit should be proportionate to the protection actually provided. Features that return economic risk to the cedant, create material basis risk or make recoveries highly conditional can reduce the expected capital benefit.
This issue is increasingly visible. EIOPA's 2026 consultation on proportional reinsurance focuses on the balance between solvency capital requirement relief and effective risk transfer. For management, the practical lesson is to document the complete economics, including commissions, experience accounts, termination rights, limits and adverse scenarios.
A structured transaction cannot be evaluated from the first-year premium alone. The actuarial model should show cash flows under expected, adverse and extreme outcomes. It should include premium adjustments, commissions, reinstatements, loss corridors, experience-account balances and the effect of early termination. Counterparty exposure and collateral should also be tested.
The output needs to be understandable outside the actuarial team. Finance should see how results move through the income statement and balance sheet. Risk management should see the residual tail. Operations should know which data and settlements are required. The board should be able to explain why the transaction is valuable without relying on opaque terminology.

A frequent source of failure is a mismatch between the actuarial assumptions and the final contract. Definitions of covered business, loss occurrence, attachment, commutation and settlement may change the economic result. Every material modelling assumption should be traced to a contractual provision or documented operational process.
The insurer should also test counterparty and liquidity risk. A recovery that arrives after a long verification period may not solve an immediate capital need. Collateral, trust arrangements, funds withheld and credit quality can affect both solvency treatment and practical security.
Structured treaties require periodic monitoring of experience, recoveries, balances and emerging risk. Changes in business mix or reserving can alter the expected benefit. Management should establish ownership for data, calculations, accounting entries, notifications and renewal decisions.
The Kompetenz helps insurers define the financial objective, compare structures, coordinate actuarial and legal review, test risk transfer and prepare the market presentation. The result is a transparent transaction designed to protect capital and earnings while remaining operationally credible.
