What is obligatory reinsurance?
Obligatory (or automatic) reinsurance is a treaty under which a ceding insurer must transfer — and the reinsurer must accept — all policies that meet a pre‑agreed set of criteria. Once the treaty is in place, individual risks within that scope are ceded automatically; the reinsurer has no case‑by‑case option to decline them. This creates a standing relationship that shifts an identified “book” or class of risks from the primary insurer to the reinsurer in exchange for a share of premium and subject to agreed terms.

Why insurers use reinsurance (brief)
Reinsurance is “insurance for insurers.” It helps primary insurers reduce exposure to large or concentrated losses, stabilize results, free up regulatory capital, and expand underwriting capacity. Obligatory treaties make that protection routine and predictable for both parties. (Source: Investopedia)
Fast fact
Over‑reliance on reinsurance has contributed to insurer failures — for example, Mission Insurance in 1985 — highlighting the importance of careful risk management and counterparty assessment. (Source: Insurance Journal)
How obligatory reinsurance works — the mechanics
– Scope definition: The treaty specifies which classes, lines, territories, limits, or other characteristics of business are covered.
– Automatic cession: Any new (and sometimes in-force) risk that falls within the scope is ceded automatically, often without prior notification.
– Reinsurer acceptance: The reinsurer must accept all such risks and share in premiums and losses per the contract’s terms.
– Term and review: Most treaties run for a fixed period and include renewal and review provisions.
Types of reinsurance relevant to obligatory treaties
– Facultative vs treaty:
– Facultative: Reinsurance for a single risk or policy, usually negotiated individually. Obligatory status is uncommon for pure facultative reinsurance, but hybrid arrangements exist where the primary can cede and the reinsurer may have limited rights.
– Treaty: Covers a defined book of business for a set period; can be obligatory (automatic) or on a proportional/non‑proportional basis. (Source: Investopedia)
– Proportional vs non‑proportional:
– Proportional (quota share, surplus): Reinsurer takes a fixed percentage of premiums and losses; reimburses a share of acquisition/administrative costs.
– Non‑proportional (excess of loss): Reinsurer pays only if losses exceed a defined retention or priority amount for a period. Obligatory treaties can be structured either way. (Source: Investopedia)
Advantages of obligatory reinsurance
– Predictability and stability: Regular flow of business and premium for reinsurer; consistent protection for cedent.
– Lower transaction costs: Transferring a book is typically less costly than negotiating many one‑off facultative placements.
– Stronger long‑term relationship: Encourages operational integration, information sharing, and coordinated portfolio management.
– Capacity building: Enables primary insurers to write larger or more lines of business with confidence.
Disadvantages and key risks
– Concentration and solvency risk: Reinsurer may be exposed to unexpectedly large accumulations of loss; if reinsurer fails, the cedent may be left with the risk it thought transferred.
– Moral hazard and adverse selection: Automatic acceptance may increase the share of poorer risks in the reinsurer’s portfolio if underwriting standards diverge.
– Ambiguity and disputes: Vague scope definitions or unclear policy descriptions can lead to disagreements and costly contract unwinding.
– Reduced flexibility: Reinsurer cannot pick or choose individual risks, limiting portfolio control.
Special considerations before entering an obligatory treaty
1. Define scope precisely
– Use clear, measurable criteria: class of business, policy limits, geographic boundaries, underwriting dates, product definitions, premium bases.
– Include examples/exclusions to remove ambiguity.
2. Due diligence on the counterparty
– Assess financial strength, ratings, capital adequacy, claims‑paying ability, reinsurance program of the reinsurer/cedent.
– Review prior loss history, portfolio quality, underwriting practices, and reserving methodology. (Mission Insurance example shows dangers of over‑reliance.) (Source: Insurance Journal)
3. Structure and pricing
– Choose proportional vs non‑proportional form based on volatility appetite and capital objectives.
– Negotiate premium ceding commissions, profit‑sharing, and sliding scale commissions if proportional.
– For non‑proportional covers, set retention, attachment points, and limits carefully.
4. Capital, accounting, and regulatory compliance
– Check solvency and reserving impacts for both parties; ensure regulatory approvals where required.
– Clarify ceded/recovered accounting treatment, collateral requirements, and credit for reinsurance rules.
5. Operational and IT readiness
– Ensure systems can automate cessions, premium and loss accounting, reporting, and data transfers.
– Agree on documentation formats, timing, and reconciliations.
6. Claims handling and dispute resolution
– Define roles for claims notification, investigation, settlements, and recoveries.
– Include arbitration or mediation clauses and jurisdiction choice for disputes.
7. Audit rights and transparency
– Provide reinsurer appropriate audit/access rights to books and underwriting files to monitor adherence to scope and standards.
8. Exit and amendment mechanics
– Include renewal negotiations, termination rights, run‑off clauses, and procedures to unwind ambiguous cessions.
Practical steps / checklist for a cedent (insurer)
Pre‑agreement
– Map the book of business proposed for cession: volumes, premiums, exposures, loss history.
– Conduct counterparty financial and operational due diligence.
– Define explicit scope, exclusions, and sample risk illustrations.
– Model expected cash flows, ceded premium, recoveries, and capital impacts.
– Get regulatory approval if required.
Contracting
– Specify treaty type (proportional or non‑proportional), ceding commission, profit share, limits, and retention.
– Set reporting cadence, data standards, and audit rights.
– Define claims process, notification timing, and payment mechanics.
– Include termination, dispute resolution, and run‑off arrangements.
Implementation and monitoring
– Configure systems for automatic cession and reconciliation.
– Perform parallel runs and reconcile premiums and loss run data.
– Monitor reinsurer credit and capital metrics; maintain contingency plans if capacity shrinks.
– Conduct periodic contract and performance reviews.
Practical steps / checklist for a reinsurer
Pre‑agreement
– Obtain full disclosure of underwriting standards, pricing methodology, and historical losses.
– Stress‑test portfolio for plausible catastrophe and accumulation scenarios.
– Price considering expected loss, expenses, profit margin, and capital cost.
– Define limits on concentration and aggregate exposure.
Contracting
– Negotiate clear eligibility criteria and exclusions.
– Include collateral or funds‑with‑held provisions if counterparty risk is material.
– Secure audit and inspection rights; require timely reporting.
– Add clauses allowing temporary capacity limits if portfolio quality deteriorates.
Ongoing management
– Monitor cession volumes and concentration per binding rules.
– Run periodic reserve reviews and loss development analyses.
– Maintain escalation process for adverse loss experience.
– Keep provisions for reducing future capacity or exit if necessary.
Governance and risk control measures
– Limits and sub‑limits: Cap exposure to a particular class, account, or geography.
– Aggregate retention: Build an aggregate retention to protect against accumulation.
– Profit‑sharing/clawback: Align incentives and provide adjustments for deteriorating experience.
– Collateralization: Use trust accounts, letters of credit, or funds‑with‑held to mitigate credit risk.
– Regular independent reviews: Actuarial, audit, and compliance oversight.
Claims handling: practical rules
– Define who has final settlement authority and how recoveries are certified.
– Set timelines for notification, reserve establishment, and recoverable reporting.
– Agree methods for subrogation, salvage, and reinsurance recoverable disputes.
When things go wrong — mitigation and contingency
– Early warning triggers: set loss ratio thresholds that require review and joint action.
– Emergency capacity plans: pre‑agreed actions (temporary rate increases, quota reductions, suspension of cessions).
– Run‑off and novation procedures: how to transfer or wind down the treaty if a party becomes insolvent.
– Legal remedies: arbitration, jurisdiction, and contract enforcement considerations.
Example lesson: Mission Insurance (brief)
Mission Insurance’s collapse (mid‑1980s) is often cited to illustrate the risk of over‑reliance on reinsurance and insufficient counterparty and reserve management. It demonstrates why both cedents and reinsurers must verify capital adequacy, reserve adequacy, and diversification rather than assuming reinsurance automatically immunizes them from insolvency.

Summary — best practices
– Be explicit: define scope, exclusions, and data requirements in writing.
– Do rigorous due diligence on counterparties and portfolios.
– Use the right structure (proportional vs non‑proportional) for your capital and volatility objectives.
– Build operational automation and controls for consistent cessions and reporting.
– Monitor performance continuously and include contractual levers to address deterioration.
– Keep contingency and exit plans ready to protect policyholders and capital.
