A ceding commission is the payment a reinsurer makes to a primary insurer to reimburse the costs of finding, underwriting, and servicing the policies being reinsured. The rate typically runs between 25% and 45% of the ceded premium and appears almost exclusively in proportional reinsurance arrangements such as quota share and surplus treaties. The logic is direct: the primary insurer already spent money acquiring customers and evaluating risks before the reinsurer entered the picture, so the reinsurer compensates that upfront investment rather than building its own distribution from scratch.
How the Payment Flows
The primary insurer transferring risk is called the cedent. The company accepting the risk is the reinsurer. Money for the commission flows one way: from the reinsurer back to the cedent. Without that reimbursement, the cedent would absorb all the acquisition costs while surrendering a share of the premium revenue.
The mechanics are easiest to see in a quota share treaty. Suppose a cedent cedes 50% of premiums and losses. On $1 million in premiums collected, the reinsurer receives $500,000. It then pays back a ceding commission — say 30% of that $500,000, or $150,000 — to cover the cedent’s share of acquisition expenses. In exchange, the reinsurer picks up 50% of every claim. Surplus treaties work similarly, though the cession varies by policy size rather than a flat percentage.
Non-proportional arrangements like excess-of-loss treaties operate differently. The reinsurer only pays when losses breach a set threshold, and the pricing structure doesn’t lend itself to the same expense-reimbursement logic. A commission or override occasionally appears in non-proportional deals, but the ceding commission as a structural element belongs to proportional reinsurance.
What the Commission Reimburses
The commission is meant to cover identifiable costs the cedent already paid to generate the business now being shared. The largest piece is usually agent and broker commissions. Property and casualty agents earn roughly 7% to 20% of the policy premium depending on the line, and those payments happen at policy inception, well before any reinsurance kicks in.
Underwriting expenses come next: salaries for the specialists who assess risk, fees for background checks and inspection reports, and actuarial analysis used to price policies. State premium taxes also factor in, generally ranging from about 1% to 3.5% of premiums depending on jurisdiction and line. General overhead rounds out the picture — office space, policy administration systems, and the technology needed to issue and service contracts.
When the commission clause pays more than actual acquisition costs, the extra portion is sometimes called an overriding commission. That margin reflects the reinsurer’s recognition that the cedent is delivering an established book with a track record, not just handing over expenses to be repaid.
Types of Ceding Commissions
Flat Commissions
A flat commission is a fixed percentage of the ceded premium, paid regardless of how the reinsured policies perform. If the treaty specifies 30%, the reinsurer pays 30% whether losses come in light or heavy. Both parties know the number upfront, billing is simple, and there are no year-end adjustments. Flat rates work well when both sides have confidence in the expected loss ratio and neither wants the administrative burden of retrospective calculations.
Sliding Scale Commissions
Sliding scale commissions adjust the percentage based on the actual loss ratio of the reinsured book. The relationship is inverse: as losses decrease, the commission rises to reward good underwriting; as losses climb, it drops toward a floor to protect the reinsurer’s margin. A typical structure might set a provisional commission at 30%, climbing to 45% if the loss ratio falls to 35%, or dropping to 25% if the loss ratio hits 65%.1IRMI. Sliding Scale Commission The slide isn’t always one-to-one. A 1% decrease in loss ratio might only produce a half-point increase in commission.
The provisional rate is what the reinsurer pays during the treaty term, before final loss experience is known. Once losses mature and the actual ratio is calculated, the commission is trued up. That adjustment can happen years after the coverage period ends, particularly for long-tail lines where claims take time to develop and settle.2IFRS Foundation.

Contingent (Profit) Commissions
Contingent commissions, often called profit commissions, are paid only if the reinsurer earns a profit on the ceded business after all claims and expenses are settled. If the reinsurer ends up in the red, the cedent gets nothing extra. The structure aligns incentives: the cedent has a direct financial reason to maintain strict underwriting standards and avoid passing along questionable risks. The tradeoff is uncertainty, since the cedent may not know for years whether the payment will materialize.
Overriding Commissions
An overriding commission exceeds the cedent’s actual acquisition and overhead costs, adding a profit element on top of pure expense recovery. In retrocession arrangements, where a reinsurer cedes business to another reinsurer, overrides may also be paid to the intermediary broker who placed the deal. The term appears in Managing General Agent arrangements as well, where an MGA receives commissions above the retail agent’s cut for managing a book on behalf of the insurer.
Risk Transfer Is a Precondition
A ceding commission only receives reinsurance accounting treatment if the underlying contract actually transfers risk. Both U.S. statutory accounting (SSAP No. 62R) and GAAP (ASC Topic 944) require that a reinsurance contract satisfy two conditions before the cedent can take balance sheet credit:
- Significant insurance risk. The reinsurer must assume meaningful exposure to loss under the reinsured policies. If the probability of significant variation in the reinsurer’s payments is remote, this condition isn’t met.
- Reasonably possible significant loss. There must be a realistic chance the reinsurer could lose money on the transaction, evaluated on a present-value basis across all cash flows between the parties.
When a contract fails either prong, it cannot be booked as reinsurance. The premium paid by the cedent is treated as a deposit, and the ceding commission is reclassified accordingly. The cedent loses the ability to reduce reserves and report the commission as an offset to acquisition costs. For a company managing capital ratios, that reclassification can meaningfully affect reported solvency.
Regulators enforce these lines. The SEC charged Assurant, Inc. with improperly booking a $10 million payment as a reinsurance recovery when a side agreement effectively eliminated the reinsurer’s exposure; Assurant settled for a $3.5 million civil penalty and a permanent injunction.3U.S. Securities and Exchange Commission. Assurant, Inc. – Litigation Release AIG paid $126 million to resolve SEC and DOJ investigations into products structured to look like reinsurance but designed to eliminate real risk to the assuming party.
One feature worth flagging in treaty negotiations is a fixed ceding commission set below the cedent’s actual acquisition costs. When the commission doesn’t cover expenses, it may signal that other terms in the contract — loss corridors, caps, or experience accounts — are cutting the reinsurer’s real exposure enough to call risk transfer into question. Contracts with that profile typically require quantitative modeling to demonstrate they still pass the two-prong test.
How Each Party Books It
The Cedent
Primary insurers track the money they spend acquiring new business as deferred acquisition costs, or DAC. These costs include agent commissions, premium taxes, and underwriting fees, which are the same expenses the ceding commission reimburses.4U.S. Securities and Exchange Commission. Deferred Policy Acquisition Costs When a cedent receives a ceding commission, that income is recorded as a direct offset to DAC on the balance sheet.5U.S. Securities and Exchange Commission. Deferred Reinsurance Ceding Commission The commission isn’t recognized as revenue all at once. It’s deferred and earned over the policy term to match the period during which the reinsured risk is active.
The matching principle prevents a cedent from booking a large commission payment as immediate income while the corresponding risk exposure stretches over months or years. If acquisition costs exceed unearned premiums and anticipated investment income, the insurer must recognize the excess as a premium deficiency charge.
The Reinsurer
The reinsurer records the ceding commission as an acquisition expense, which reduces its net income relative to the premiums it receives.2IFRS Foundation. AP3 – Commissions and Reinstatement Premiums in Reinsurance Contracts Issued Under statutory accounting, that expense is recognized over the policy term rather than all at once. The reinsurer’s combined ratio incorporates the ceding commission as part of its expense ratio. A reinsurer paying a 35% ceding commission on a book with a 60% loss ratio is running a 95% combined ratio before its own internal overhead, leaving thin margins.
SSAP No. 62R also requires both parties to maintain documentation showing the commission reflects genuine acquisition costs. Those records are subject to examination by state insurance departments, and inconsistencies between the commission structure and the underlying economics of the treaty tend to surface during routine financial analysis at the NAIC level.
Federal Tax Treatment
Tax treatment splits between the two parties. The cedent reports the ceding commission as non-premium-related income rather than using it to reduce general deductions.6eCFR. Other Insurance Companies – 26 CFR Part 1 The reinsurer treats the commission as a general deduction.
Both parties are also subject to IRC Section 848, which requires insurance companies to capitalize a portion of policy acquisition expenses rather than deducting them immediately. Capitalization rates vary by product: 9.2% of net premiums for most property and casualty contracts, 2.45% for group life insurance, and 2.09% for annuities.7Office of the Law Revision Counsel. 26 U.S. Code 848 – Capitalization of Certain Policy Acquisition Expenses The capitalized amounts are then deducted ratably over 180 months (15 years), though the first $5 million of specified policy acquisition expenses qualifies for a shorter 60-month amortization period.
Assumption reinsurance, where the reinsurer takes over the policies entirely rather than sharing them, adds a layer. The reinsurer must capitalize the ceding commission as a deferred expense. Part of that amount is deducted through the Section 848 mechanism, and the remainder becomes the adjusted basis of an intangible asset amortized over 15 years under Section 197.8IRS. Application of Section 338 to Insurance Companies Getting the allocation wrong between Section 848 and Section 197 can create years of mismatched deductions, which is why this piece typically warrants specialist tax review.
