Definition:Indemnity reinsurance

🔁 Indemnity reinsurance is the traditional form of reinsurance in which the reinsurer agrees to reimburse the ceding insurer for actual losses incurred on the underlying policies, rather than making payments based on a parametric index or other non-indemnity trigger. This structure preserves the principle of indemnity at the reinsurance level: the cedent must demonstrate that it has sustained a genuine financial loss before the reinsurer's obligation is activated. Indemnity reinsurance stands in contrast to parametric or industry loss warranty arrangements, where payouts are determined by an external metric regardless of the cedent's actual experience.

⚙️ Under an indemnity reinsurance contract—whether structured as proportional ( quota share, surplus share) or non-proportional ( excess of loss, stop loss)—the reinsurer follows the fortunes of the cedent. When a covered claim is paid, the cedent submits a bordereau or individual claim report, and the reinsurer reimburses its share based on the contract terms. Because recovery depends on the cedent's actual net loss, accurate and timely loss reporting, supported by sound reserving practices, is critical. The follow-the-fortunes and follow-the-settlements doctrines that underpin indemnity reinsurance mean the reinsurer generally cannot second-guess the cedent's good-faith claim payments, though disputes can arise when payments fall outside the agreed scope of coverage.

💡 Indemnity reinsurance remains the dominant mechanism by which primary insurers manage volatility, protect solvency, and expand underwriting capacity. Its alignment of reinsurer and cedent interests—since the reinsurer only pays when the cedent actually loses money—creates a natural incentive for both parties to focus on underwriting quality and claims discipline. This contrasts with non-indemnity products, which can introduce basis risk when the payout does not match the actual loss. Regulatory frameworks, including Solvency II and U.S. risk-based capital standards, grant favorable capital treatment to indemnity reinsurance arrangements that meet risk transfer tests, reinforcing the structure's centrality to the global reinsurance market.
