Reinsurance

Concept and Function

Reinsurance is the contract by which an insurer procures another insurer to insure it against loss or liability arising from an insurance policy or a defined portfolio of insurance policies. The first insurer is commonly called the ceding insurer, cedent, or reinsured; the second insurer is the reinsurer or assuming insurer.

Reinsurance is insurance of an insurer's risk. The risk transferred is not the property, life, health, liability, or casualty risk of the original insured in its direct form, but the insurer's exposure to pay because it issued the original insurance. The original policy remains the source of the cedent's liability, while the reinsurance contract is the source of the reinsurer's liability.

The practical purpose of reinsurance is to distribute large or numerous risks, stabilize loss experience, increase underwriting capacity, protect solvency, reduce concentration in catastrophic exposures, and allow insurers to write risks that exceed their desired retention. It is also used to manage capital, align portfolios, obtain underwriting support, and protect against unusual severity or frequency of claims.

Reinsurance may cover all or part of the insurer's risk. It may relate to a single policy, a specified percentage of each policy in a class, losses above a defined retention, catastrophe losses from one event, aggregate losses over a period, or other exposures defined by the agreement.

Legal Character

Separate Contract

Reinsurance is distinct from the original insurance. The original insurance is between the insurer and the insured; the reinsurance is between the cedent and the reinsurer. The original insured ordinarily does not become a party to the reinsurance contract and does not acquire rights under it merely because the original policy was reinsured.

The reinsurance contract is governed by its own terms on subject matter, attachment, duration, premium, limits, exclusions, warranties, notice, claims handling, settlement authority, and dispute resolution. The original policy may influence the reinsurer's exposure only to the extent that the reinsurance incorporates, follows, or refers to the original coverage.

Reinsurance does not cancel, reduce, novate, or transfer the direct insurer's obligation to the policyholder. The cedent remains liable to the original insured even if the reinsurer refuses to pay, becomes insolvent, contests coverage, or delays reimbursement. The policyholder's contract is with the direct insurer, and the direct insurer cannot defeat the policyholder's claim by invoking problems in its reinsurance recovery.

Contract of Indemnity Against Liability

The Insurance Code treats reinsurance as presumptively an indemnity against liability, not merely an indemnity against actual damage after payment. This means that, unless the contract provides otherwise, the cedent's right to recover may arise when its liability under the original insurance has become fixed, even if the cedent has not yet actually paid the original insured.

The presumption matters when the cedent's liability is established by judgment, binding settlement, adjustment, arbitration, or other contractually recognized determination. If the reinsurance wording requires loss to be paid before recovery, the cedent must satisfy that contractual condition. If the wording indemnifies liability, a prior actual disbursement by the cedent is not indispensable once liability is definite and within the reinsured risk.

The reinsurer's obligation is still limited by the reinsurance contract. A cedent cannot recover for an ex gratia payment, a compromise outside the original coverage, a loss excluded by the reinsurance, or an amount beyond the reinsured limit unless the contract clearly covers that exposure.

Parties and Working Terms

The cedent has an insurable interest in the reinsurance because it may suffer loss or liability under the original insurance. That interest is measured by the cedent's exposure, not by ownership of the original insured's property or life. If the cedent has no possible liability on the original policy, there is generally no reinsured loss to indemnify, subject to contract wording on settlements, defense costs, and related expenses.

Premium in reinsurance is the consideration paid by the cedent to the reinsurer. In proportional arrangements, the reinsurer commonly receives a corresponding share of the original premium and may pay a ceding commission. In non-proportional arrangements, the reinsurer's premium is usually priced by layer, attachment point, limit, exposure, loss experience, and reinstatement terms.

Principal Forms

Facultative and Treaty Reinsurance

Facultative reinsurance is negotiated risk by risk. The cedent may offer a particular policy or exposure, and the reinsurer may accept, reject, or modify the proposed terms. It is useful for unusual, large, hazardous, or nonstandard risks that fall outside automatic capacity or require individual underwriting.

Treaty reinsurance covers a class, line, portfolio, or category of business under prearranged terms. Once a risk falls within the treaty, the cedent cedes and the reinsurer assumes the risk according to the treaty. Treaty reinsurance allows speed, automatic capacity, and consistent portfolio treatment.

An automatic treaty reduces individual disclosure at the moment each covered risk is ceded, but it does not remove the cedent's obligation of good faith in forming and performing the treaty. The cedent must not use a treaty to pass off risks that are knowingly outside the agreed class, concealed by manipulation, or written contrary to treaty underwriting conditions.

Proportional and Non-Proportional Reinsurance

In quota share reinsurance, the cedent and reinsurer share every covered risk in a fixed percentage. It is simple and gives immediate capacity, but it also requires the cedent to share profitable small risks that it might otherwise retain.

In surplus share reinsurance, the cedent retains a defined line and cedes only the surplus above that retention. It allows the cedent to keep more of smaller risks and obtain capacity for larger risks.

In excess of loss reinsurance, the reinsurer indemnifies losses exceeding a stated retention up to a stated limit. The layer may respond per risk, per occurrence, per event, or per aggregate period, depending on the wording.

In catastrophe reinsurance, the reinsurer protects the cedent against accumulation of losses from a single catastrophic occurrence or event. The definition of event, hours clause, territorial scope, aggregation language, and excluded perils become central to determining recovery.

In stop loss reinsurance, the reinsurer protects against an adverse aggregate loss ratio or total loss amount over a period. This form addresses frequency and overall portfolio deterioration rather than a single large claim.

Disclosure and Utmost Good Faith

Reinsurance is subject to the principle of utmost good faith. The cedent knows more about its underwriting, policy terms, risk selection, loss history, claims practices, and insureds than the reinsurer ordinarily can know. The reinsurer relies on the cedent to present the risk honestly and completely.

The Insurance Code requires an insurer obtaining reinsurance, except under automatic reinsurance treaties, to communicate the representations of the original insured and all knowledge and information it possesses that are material to the risk. Materiality is judged by whether the information would influence a prudent reinsurer in accepting the risk, pricing the risk, fixing limits, imposing conditions, or rejecting the cession.

Material information may include the original policy terms, warranties, exclusions, values, hazard details, prior losses, claims-made circumstances, concentration of exposure, occupancy, prior cancellations, underwriting exceptions, known defects, moral hazard indicators, pending claims, and any deviation from normal underwriting guidelines. The duty covers material knowledge acquired before placement and, where relevant to the placement or continuation of the reinsurance, subsequently acquired information.

Concealment or material misrepresentation by the cedent may avoid the reinsurance or give the reinsurer contractual remedies. The rule is stricter in facultative reinsurance because the reinsurer evaluates the individual risk based on the cedent's presentation. In treaty reinsurance, the same good-faith standard applies to treaty formation, bordereaux, accounts, risk classifications, and compliance with underwriting conditions.

The reinsurer also owes good faith. It must not accept premium while intending to evade valid claims, impose post-loss grounds not found in the contract, misuse access to confidential underwriting information, or withhold payment contrary to the agreed claims mechanism.

Liability of the Reinsurer

The reinsurer's liability depends on three connected inquiries: whether the original insurer is liable or has made a covered settlement, whether the risk or loss falls within the reinsurance, and whether the cedent has complied with the reinsurance conditions. The original policy may establish the cedent's exposure, but the reinsurance wording determines the reinsurer's share.

A reinsurer may raise defenses arising from the reinsurance contract itself, such as non-disclosure, breach of warranty, late notice when material under the wording, exclusions, limits, attachment point, territorial restrictions, temporal restrictions, non-payment of reinsurance premium, or failure to submit required accounts. It may also rely on defenses showing that the cedent had no covered liability under the original policy, unless the reinsurance validly binds the reinsurer to the cedent's good-faith settlement.

Many reinsurance contracts contain follow-the-fortunes or follow-the-settlements language. Such clauses generally require the reinsurer to accept the cedent's reasonable, good-faith underwriting or settlement decisions when the loss is arguably within the original policy and within the reinsurance. They do not require the reinsurer to pay for fraud, collusion, bad faith, purely voluntary payments, losses clearly outside the reinsured contract, or amounts beyond agreed limits.

Claims cooperation or claims control clauses may require timely notice, consultation, access to records, consent before settlement, or reinsurer participation in defense. Breach of these clauses is significant when the clause is a condition of liability or when the breach prejudices the reinsurer's rights under the contract.

Loss adjustment expenses, defense costs, extra-contractual obligations, penalties, attorney's fees, and interest are recoverable from the reinsurer only if the reinsurance wording covers them or if they are treated as part of the covered loss under the agreed terms. The cedent should not assume that all consequences of a direct claim automatically pass to the reinsurer.

Rights of the Original Insured

The original insured has no interest in the ordinary contract of reinsurance. The reinsurance proceeds belong to the cedent, and the insured's direct claim remains against the insurer that issued the policy. The insured generally cannot sue the reinsurer merely because the insurer ceded the policy, because there is no privity between them.

A different result may follow when the reinsurance contract contains a clear stipulation in favor of the original insured, a direct payment or cut-through clause, an assumption of policy obligations, or another arrangement that creates enforceable rights in the policyholder. The right must arise from the reinsurance wording or a valid transfer of obligation, not from the mere existence of reinsurance.

Assumption reinsurance must be distinguished from ordinary indemnity reinsurance. In ordinary reinsurance, the reinsurer indemnifies the cedent and the cedent remains the direct obligor. In assumption reinsurance, the assuming insurer takes over direct policy obligations, usually with regulatory supervision and policyholder-facing consequences. Assumption reinsurance may operate like a transfer or novation of insurance obligations when legally and contractually completed.

Operational Clauses

A reinsurance contract commonly states the business covered, period of coverage, territorial scope, classes of risks, retention, limits, exclusions, premium calculation, ceding commission, reporting schedule, bordereaux, loss notice, access to records, claims handling, settlement authority, currency, taxes, commutation, termination, run-off, and dispute mechanism.

The retention defines the cedent's own share. A cedent that exceeds its underwriting authority, misstates retention, or secretly shifts more risk than permitted may breach the reinsurance. Retention provisions matter because reinsurers price the contract on the assumption that the cedent keeps meaningful risk and therefore has an incentive to underwrite carefully.

The attachment point identifies when a non-proportional layer begins to respond. If the cedent's loss does not exceed the attachment point, the reinsurer owes nothing under that layer. If the loss exceeds the attachment point, the reinsurer pays only within the layer and subject to reinstatement, aggregate limits, and event definitions.

An errors and omissions clause may excuse clerical or inadvertent mistakes in reporting cessions or accounts when the mistake is promptly corrected and no bad faith is present. It does not excuse deliberate concealment, underwriting outside treaty terms, or a material change in the risk assumed.

Termination of a reinsurance treaty is usually prospective. Risks that attached before termination may remain covered in run-off unless the parties agree to portfolio withdrawal, portfolio transfer, commutation, or another mechanism that ends or restructures existing liabilities. Cancellation of reinsurance does not cancel the original policies.

Regulatory and Insolvency Effects

Reinsurance is part of insurer solvency supervision. Domestic insurers use reinsurance to manage risk, but they remain responsible for maintaining adequate capital, reserves, liquidity, and claims-paying ability. A reinsurance program that merely moves risk on paper without reliable recoverability does not substitute for sound capitalization.

Credit for reinsurance, reserve treatment, admissibility of recoverables, and recognition of foreign or domestic reinsurers are matters of regulatory concern. The commercial effect of a treaty between cedent and reinsurer does not automatically mean that the cedent may treat every recoverable as fully available capital for regulatory purposes.

If the cedent becomes insolvent, ordinary reinsurance recoverables are generally assets of the insolvent insurer's estate or liquidation proceedings, not direct property of individual policyholders. Payment is made according to the reinsurance contract and applicable insolvency arrangements. A policyholder obtains direct payment from the reinsurer only when a valid clause or legal arrangement gives that right.

If the reinsurer becomes insolvent, the cedent remains liable to its policyholders and must pursue its reinsurance claim in the reinsurer's insolvency process. The cedent bears the credit risk of the reinsurer unless the contract is protected by collateral, trust, funds withheld, letters of credit, or other security recognized by the parties and regulators.

Related Distinctions

The central rule is that reinsurance reallocates risk between insurers without disturbing the original insured's right to demand performance from the direct insurer. The cedent buys protection for its own liability, the reinsurer assumes only the contractually defined reinsured exposure, and the original policyholder remains protected by the direct insurance contract unless a separate lawful arrangement changes that relationship.
