How assumption reinsurance works: A guide for insurance brokers

Reinsurance News

By Ramon Berenguer

Among the various types of reinsurance, assumption reinsurance stands out for its unique approach to transferring obligations and liabilities. Understanding how assumption reinsurance works is crucial for brokers advising clients on risk transfer strategies.  

When a reinsurance contract is executed, the ceding insurer’s obligations are transferred to the reinsurer, who then assumes all rights and responsibilities associated with the policies. This guide will clarify how this type of reinsurance operates and what it means for insurance companies, brokers, and policyholders alike. 

What is assumption reinsurance?  

Assumption reinsurance is a type of reinsurance agreement in which a reinsurer takes over the primary insurer’s entire contractual obligations for certain policies. In this arrangement, the reinsurer becomes directly liable to the policyholders. This means that they effectively “assume” all rights, responsibilities, and risks associated with those policies.  

This differs from indemnity reinsurance, where the original insurer remains responsible to policyholders and the reinsurer only reimburses the insurer for claims paid. In the US, assumption reinsurance typically requires regulatory approval and, in most states, the consent of affected policyholders.  

The process involves transferring policy administration, claims handling, and all future liabilities to the reinsurer. Policyholders are notified and may need to agree to the transfer, ensuring transparency and protection of their rights. 

Key points of assumption reinsurance: 

  • The reinsurer replaces the original insurer as the direct insurer for the affected policies. 
  • Policyholder consent and regulatory approval are often required. 
  • The transaction is used in portfolio transfers, company exits, or restructuring. 

Assumption reinsurance provides a clean break for the ceding insurer and clarity for policyholders, as they now deal directly with the new insurer for all policy matters. Assumption reinsurance, however, is only one type of reinsurance. If you need to know more about the other types of reinsurance, check out our guide to the most common types of reinsurance.  

How assumption reinsurance works 

This process ensures that the ceding company can effectively manage its risk exposure. It also ensures that primary insured receives clear communication about who is liable for their coverage and that reinsurer assumes all contractual obligations under the reinsurance agreement.  

Here's how it works:  

Step 1. Identify the need for risk transfer 

The original insurance company (the ceding company) evaluates its portfolio. Typically, they would then determine that transferring a specific line of business or group of reinsured risks will improve its risk management strategy. 

Step 2. Select the type of reinsurance contract 

The ceding insurer, often with broker guidance, chooses between types of contracts. In most cases, this is between assumption reinsurance or indemnity reinsurance.  

In assumption reinsurance, the reinsurer assumes full responsibility for the original insurance obligations. Meanwhile, in indemnity reinsurance, the reinsurer agrees to indemnify the ceding insurance company without direct policyholder involvement. 

Step 3. Structuring the reinsurance agreement 

A reinsurance contract is drafted, outlining the terms under which the ceding company will transfer the designated line of business to the reinsurer. The contract specifies which policies and reinsured risks are included. 

Step 4. Getting regulatory and policyholder approvals 

US regulations require that the transaction be reviewed and approved by state insurance regulators. Policyholders (primary insured) are notified, and in most states, their consent is required before the transfer can proceed. 

Step 5. Doing the transfer of obligations 

Once approvals are secured, the ceding insurer’s obligations under the original insurance policies are formally transferred to the reinsurer. The reinsurer assumes all rights, responsibilities, and liabilities for the covered policies. 

Step 6. Policyholder notification and transitioning policies 

The primary insured is informed that the reinsurer is now directly responsible for their policy. All future claims, servicing, and communications are handled by the reinsurer. 

Step 7. Doing ongoing risk management and monitoring 

Finally, insurance brokers continue to support clients by monitoring the performance of the reinsurance agreement. This ensures that the reinsurer fulfills its obligations. Brokers can also give advice on future risk management strategies.

Real world examples of assumption reinsurance treaties 

Here are some recent cases where reinsurers got into assumption reinsurance contracts:  

1. RGA’s acquisition of John Hancock’s US group life, disability, and accident business (2021) 

RGA entered an assumption reinsurance agreement with John Hancock, taking over a block of the latter's group life, disability, and accident insurance policies. Through this transaction, RGA became directly liable to the policyholders. This deal shows how assumption reinsurance can facilitate a ceding company’s exit from a specific line of business while ensuring continuity for the primary insured. 

2. Swiss Re’s assumption of closed blocks from US life insurers (2020–2023) 

Swiss Re has completed several assumption reinsurance transactions in recent years, acquiring closed blocks of life insurance from US carriers. In these deals, Swiss Re assumed all policyholder obligations, providing the ceding company with capital relief and policyholders with a new, financially strong insurer. 

3. Munich Re America’s assumption of long-term care blocks (2022) 

Munich Re America has engaged in assumption reinsurance agreements with US insurers seeking to transfer legacy long-term care insurance portfolios. These transactions allowed the ceding company to reduce risk exposure and administrative burden, while Munich Re America became the direct insurer for the affected policyholders. 

4. Global Atlantic’s assumption reinsurance with Allstate Life Insurance Company (2021) 

Global Atlantic entered an assumption reinsurance agreement with Allstate Life Insurance Company, taking over a significant block of fixed annuity and life insurance policies. This transaction involved regulatory approval and policyholder notification, with Global Atlantic assuming all future liabilities and servicing responsibilities. 

Key benefits of assumption reinsurance   

Using this type of reinsurance brings several advantages to insurance brokers, including:  

1. Complete transfer of liability 

The reinsurer assumes full responsibility for the reinsured risks, making them directly liable to the policyholder. This provides a clean break for the ceding company, as all obligations under the original insurance contract are transferred. 

2. Capital relief and balance sheet optimization 

By transferring a block of business, the ceding insurer can free up capital, improve solvency ratios, and better manage its balance sheet. This is especially useful for insurers looking to exit a line of business or reduce exposure to long-duration risks. 

3. Streamlined policy administration 

The reinsurer takes over policy administration, claims handling, and customer service for the affected policies. This reduces the operational burden and administrative costs for the ceding company. 

4. Regulatory and strategic flexibility 

Assumption reinsurance can help insurers meet regulatory requirements, restructure their portfolios, or focus on core lines of business. It is often used as part of mergers, acquisitions, or strategic exits. 

5. Policyholder clarity and continuity 

Policyholders are notified of the transfer and deal directly with the new insurer, ensuring transparency and continuity of coverage. This can enhance trust and reduce confusion compared to indemnity reinsurance, where the original insurer remains involved. 

6. Risk management 

Assumption reinsurance allows the ceding company to transfer specific risks like mortality, longevity, or long-term care. The transfer is typically done to a reinsurer with specialized expertise and capacity, supporting overall risk management objectives. 

Assumption reinsurance vs. traditional reinsurance 

How does this type of reinsurance compare to traditional forms of reinsurance? Their main difference is that assumption reinsurance results in a full transfer of policy obligations and direct policyholder relationship to the reinsurer, often requiring regulatory and policyholder approval.  

In contrast, traditional or indemnity reinsurance works as a risk-sharing arrangement where the original insurer retains the policyholder relationship. Also, the reinsurer simply indemnifies the insurer for covered losses. Here’s a summary of how they compare:  

Feature 

Assumption reinsurance 

Traditional reinsurance 

Liability to policyholder 

Reinsurer becomes directly liable to the policyholder; the original insurer is released from all obligations 

Original insurer remains liable to the policyholder; reinsurer only reimburses the insurer 

Policyholder consent 

Typically requires regulatory approval and policyholder consent 

Policyholder consent is not required; only insurer and reinsurer are parties to the contract 

Transfer of obligations 

Complete transfer of all rights, responsibilities, and administration to the reinsurer 

Only the financial risk is transferred; administration and claims handling remain with the original insurer 

Purpose 

Used for portfolio transfers, company exits, or restructuring

Less regulatory involvement; viewed as a business-to-business transaction 

Examples 

Block transfers of life, annuity, or long-term care policies 

Quota share, excess-of-loss, or facultative reinsurance contracts 

 
Assumption reinsurance vs. Novation 

More experienced insurance brokers or those with a background in law may notice similarities between this type of reinsurance and novation. Novation and assumption reinsurance are similar in several important ways, especially in the context of insurance and reinsurance transactions. 

Here’s a comparison to show their similarities and differences:  

Feature

Contract structure 

The original insurance contract remains in force, but the reinsurer steps in as the new insurer for affected policies 

The original contract is extinguished and replaced by a new one; the new party assumes all rights and obligations 

Policyholder consent

When should brokers use assumption reinsurance? 

Assumption reinsurance is best used for complete, permanent transfers of policy blocks. This is especially applicable when an insurer seeks a clean exit, improved capital management, or operational simplification. It ensures policyholders have continuity of coverage with a new, directly responsible insurer. 

Impact of assumption reinsurance on clients and carriers 

This type of reinsurance provides policyholders with continuity and clarity about who manages their policy. At the same time, it allows insurance carriers to efficiently transfer risk, free up capital, and simplify their operations. Here’s a rundown of effects on clients and carriers:  

On clients or policyholders 

  • Direct relationship change: Policyholders’ contracts are transferred to a new insurer (the reinsurer), who becomes directly responsible for claims, policy administration, and customer service 

  • Continuity of coverage: The terms and benefits of the original insurance policy remain unchanged, ensuring uninterrupted coverage 

  • Notification and consent: Clients are notified of the transfer and, in most cases, must provide consent. This ensures transparency and allows clients to be aware of who is now responsible for their policy 

  • Potential for improved service: If the new insurer specializes in the relevant line of business, clients may benefit from more focused expertise or resources 

On carriers or insurance companies 

  • Risk and liability transfer: The ceding insurer is fully relieved of all future obligations and liabilities for the transferred policies, reducing risk exposure and administrative burden 

  • Capital relief: By removing liabilities from the balance sheet, the original carrier can free up capital, improve solvency ratios, and focus on core business areas 

  • Operational simplification: The ceding company no longer needs to service or administer the transferred policies, streamlining operations 

  • Regulatory compliance: The transaction may help carriers meet regulatory requirements for risk concentration or capital adequacy 

Assumption reinsurance offers insurance brokers and carriers an effective solution for transferring risk, increasing operational efficiency, and optimizing capital. By understanding how this approach works and its implications for both policyholders and insurers, brokers can provide informed guidance on portfolio transfers and strategic business changes.  

With clear benefits for all parties involved, assumption reinsurance remains a valuable option for managing risk and supporting long-term business goals.
