Structuring a Marine Catastrophe Bond: From Exposure Data to Investor Package

The ILS market is dominated by US wind and quake because those perils have standardised exposure data, mature vendor models and a long loss record. Marine has none of that by default: exposure sits in schedules of vessels, voyages, ports and cargo interests that change continuously, and loss data is fragmented across hull, cargo, liability and specialty lines.

That is a data-engineering obstacle, not a conceptual one. Sponsors who invest in exposure structuring can bring marine perils to investors credibly.

Before any structuring, the portfolio needs a stable, auditable exposure representation: insured interests with values, geocoded locations or route geometries, time-on-risk, peril attribution, policy limits and deductibles, and a reconciled bridge from the portfolio to the accounting numbers.

Investors and their modelling agents will test that bridge. A portfolio that cannot reconcile will be priced with an uncertainty loading far larger than the cost of fixing the data.

Peril definition and trigger definition are a single design decision. An indemnity trigger requires an airtight definition of covered loss, claims control, reporting cadence and loss-development treatment. An industry-loss or parametric trigger shifts the burden to index construction and basis-risk analysis but removes investor exposure to the sponsor's claims philosophy.

For marine perils such as port accumulation, cargo concentration, flood at terminals or named-storm damage to fixed marine assets, modelled-loss and parametric designs are often quicker to place than indemnity.

Attachment and exhaustion should be set from the modelled loss distribution and from the sponsor's capital objective, not from the spread the sponsor hopes to pay. The relevant outputs are expected loss, attachment probability, exhaustion probability, conditional expected loss given attachment, and the multiple of expected loss implied by indicative spreads.

Sponsors should also model what the layer does to their own solvency position and reinsurance programme, so that the ILS layer is complementary to traditional cover rather than duplicative.

The package that actually moves a transaction contains a documented model with reproducible assumptions, sensitivity analysis around the key parameters, a historical event re-run, a clear reset mechanism, event-notification and reporting commitments, and a plain statement of what is excluded and why.

Independent analytical review of that package — commissioned by the sponsor before marketing — consistently shortens the placement process, because it removes the objections investors would otherwise raise late.
