Definition:Assumed premium
💰 Assumed premium is the premium income that an insurer or reinsurer receives — or expects to receive — for accepting risk transferred from another insurer under a reinsurance agreement. When an insurer cedes a portion of its book of business to a reinsurer, the corresponding share of premium that flows to the reinsurer is recorded as assumed premium on the reinsurer's books, while the ceding company records it as ceded premium.
📊 The mechanics depend on the type of reinsurance arrangement. In a quota share treaty, the reinsurer assumes a fixed percentage of every policy's premium within the defined portfolio — if the treaty cedes 30%, the reinsurer's assumed premium equals 30% of the underlying gross written premium. Under excess of loss contracts, the assumed premium is typically a negotiated flat or variable amount that compensates the reinsurer for covering losses above a specified retention. Assumed premiums appear on the reinsurer's financial statements and statutory filings, and they must be matched against corresponding loss reserves and unearned premium reserves to present an accurate picture of the reinsurer's obligations.
🔍 Tracking assumed premium accurately is essential for multiple stakeholders. For reinsurers, it represents top-line revenue and is a key input into pricing adequacy analysis, capital allocation, and solvency calculations. Regulators and rating agencies scrutinize the relationship between assumed premiums and incurred losses to assess whether a reinsurer is writing business profitably and reserving appropriately. For the broader market, the volume and pricing trends in assumed premiums serve as a gauge of reinsurance market capacity and appetite — rising assumed premiums across the industry can signal either growing demand for risk transfer or a hardening reinsurance cycle.
