Non-Proportional Reinsurance

Excess of Loss
Tail Risk Protection

Structured non-proportional coverage designed to protect cedents against severe loss events, optimize solvency capital, and smooth earnings volatility through precision-layered treaties.

Precise Attachment. Strategic Limits.

Excess of Loss (XoL) reinsurance triggers when a cedent's losses exceed a predetermined retention or attachment point. Aevum Zenth structures multi-layer XoL programs tailored to your portfolio's risk profile, regulatory capital requirements, and earnings volatility targets.

📊

Capital Optimization

Reduce Solvency II / RBC capital charges by transferring tail risk. Our XoL structures are calibrated to maximize capital relief while preserving profitable book growth.

🛡️

Earnings Volatility Smoothing

Mitigate the impact of large losses and catastrophe events. Stabilize quarterly results and maintain dividend consistency for shareholders and regulators.

⚖️

Flexible Attachment Points

Custom retention levels aligned with your underwriting appetite. From per-occurrence ILW to financial excess, we structure layers that match your risk tolerance.

🌍

Global Capacity & Placement

Access multi-national syndicate capacity, ILS capital markets, and corporate balance sheet through a single point of execution with Aevum Zenth.

Tailored Treaty Structures

Select from industry-standard or bespoke XoL configurations designed for property, casualty, specialty, or financial lines portfolios.

🌪️

Per-Occurrence XoL

Covers aggregate losses from a single event (e.g., hurricane, earthquake, major liability claim) once the attachment point is breached. Ideal for catastrophe risk transfer.

📑

Contract / ILW XoL

Incurred Loss Within coverage protects against large individual policy losses across lines. Triggered when a single risk loss exceeds retention, regardless of occurrence.

💰

Financial Excess of Loss

Capital market-linked structures that optimize balance sheet metrics, provide loan collateral, or facilitate regulatory capital management without traditional indemnity claims.
