Proposition

Treaty reinsurance is the foundation of Guarant's portfolio. The Company writes both proportional and non-proportional treaty structures for cedants across all ten specialty lines of business.

Proportional programmes include quota share and surplus share treaties. Non-proportional programmes include per-risk excess of loss, catastrophe excess of loss and aggregate stop-loss covers. Structures are tailored to each cedant's retention strategy, portfolio profile and capital requirements.

Treaty types

Quota share

The cedant cedes a fixed proportion of every risk within the treaty scope to Guarant. Premium and losses are shared in the same proportion. Quota share treaties provide cedants with predictable capacity, stable loss ratios and proportional capital relief across their book.

Surplus share

The cedant retains each risk up to a defined retention and cedes the surplus to Guarant, up to an agreed number of lines. Surplus share treaties allow cedants to retain smaller and more favourable risks in full while transferring larger exposures that exceed their net appetite.

Per-risk excess of loss

Guarant responds when an individual risk loss exceeds a defined deductible, paying up to the agreed limit. Per-risk XoL protects cedants against severity on single risks without transferring attritional premium.

Catastrophe excess of loss

Covers aggregate losses from a single catastrophic event that affects multiple risks simultaneously. Cat XoL is essential for cedants with exposure to natural catastrophe, industrial disaster or accumulation perils.

Aggregate stop-loss

Caps the cedant's total claims burden across the portfolio over a defined period, typically expressed as a loss-ratio trigger. Stop-loss treaties protect against sustained adverse experience across the entire book, stabilising annual results.

Underwriting and pricing

Treaty pricing is experience-rated, exposure-rated or a blend of both methodologies, depending on the maturity of the cedant relationship and the availability of historical data. Catastrophe-exposed treaties are priced with the support of vendor catastrophe models.

The pricing methodology applied to each programme is disclosed to the cedant's broker at the indicative-terms stage, ensuring transparency throughout the negotiation process.
