Meaning
A reinsurance structure provides coverage for losses that exceed a specific predetermined dollar threshold, often called a retention or attachment point. This excess of loss insurance operates as a protective layer for the primary insurer or the policyholder by triggering indemnity only when the total claim amount surpasses the defined limit. The contract protects against large, unpredictable losses rather than high-frequency events.
Underwriting Logic
Underwriters assess the historical loss data of the cedent to determine a probable maximum loss before setting the attachment point. A lower attachment point leads to higher premium costs because the likelihood of the reinsurer making a payment increases significantly. The structure allows primary insurers to stabilize their balance sheets by transferring the volatility of large catastrophic risks to another entity.
Financial Mechanism
Total loss amounts calculated across multiple policies or within a single event define the eligibility of the claim. Recovery occurs for the difference between the total loss and the attachment point, capped at a maximum specified limit set within the reinsurance agreement. This layering mechanism prevents the primary insurer from absorbing the entirety of a severe financial shock.
Contractual Boundary
Agreements regarding this coverage remain limited by exclusions that define which perils fall outside the scope of the indemnity. Provisions regarding aggregate annual limits protect the reinsurer from a cumulative series of claims occurring within a single policy period. Precise language in the underlying contract dictates the exact point where liability transfers from the cedent to the reinsurer.
