Definition:Reinsurance cession
🔄 Reinsurance cession is the act by which a ceding company transfers a defined portion of risk — and the corresponding share of premium — to a reinsurer under a reinsurance agreement. Each individual transfer of risk constitutes a cession, and the term also refers to the portion of business that has been ceded. A cession can occur automatically under a treaty arrangement, where risks falling within agreed parameters are transferred without case-by-case approval, or on an individual basis through facultative reinsurance.
⚙️ Under a quota share treaty, for example, the ceding company cedes a fixed percentage of every risk in a specified line of business, along with the same percentage of premium, and the reinsurer pays back a ceding commission to cover the cedent's acquisition and administrative expenses. In an excess of loss structure, the cession operates differently: the cedent retains losses up to a retention level and cedes only the layer above that attachment point. The mechanics of each cession — what triggers it, how premium is calculated, and what terms govern the reinsurer's liability — are spelled out in the underlying treaty or facultative certificate. Accurate tracking of cessions is critical for bordereaux reporting, which provides reinsurers with detailed data on the business they have assumed.
📈 Getting cessions right has far-reaching consequences for a primary insurer's financial health and strategic flexibility. Each cession directly affects the cedent's net retention, loss ratio, and solvency metrics, so errors or ambiguities in recording cessions can distort financial statements and lead to disputes during loss recoveries. Regulators scrutinize cession arrangements to ensure that risk transfer is genuine and that cedents are not using reinsurance purely for cosmetic balance-sheet relief. For technology-forward insurers and insurtech platforms, automating cession workflows — from policy-level data capture through to reinsurer reporting — has become a competitive priority, reducing manual reconciliation and accelerating the speed at which reinsurance programs can scale.
