Reinsurance is the transfer of all or part of an insurer's assumed risk to another insurer or a reinsurer. Often referred to as insurance for insurers, reinsurance enables risk sharing in both premiums and claims, helping insurers strengthen their financial capacity and manage exposures more effectively.

Participation reinsurance applies these principles within a participation-based insurance framework, supporting the sustainable development and resilience of the participation insurance ecosystem.

According to AAOIFI Shariah Standard No. 41 on Islamic Reinsurance, Islamic reinsurance is defined as an arrangement whereby insurance companies, acting on behalf of the insurance funds under their management that are exposed to specific risks, obtain reinsurance coverage to indemnify a portion of the losses arising from those risks. This arrangement is funded through the allocation of a portion of the participants' contributions, which are paid based on the principle of donation (tabarru). These contributions form a reinsurance fund that possesses a distinct legal personality and an independent financial liability. Through this fund, losses arising from certain risks insured by the insurance company and otherwise payable by the company are compensated in accordance with the terms of the reinsurance arrangement. Under AAOIFI Shariah Standard No. 41, the rules governing reinsurance arrangements between Islamic insurance companies and conventional reinsurance companies are as follows:

• An Islamic insurance company should engage Islamic reinsurance providers to the greatest extent possible.

• An Islamic insurance company may not maintain cash reserves allocated for potential claims with a conventional reinsurance company where such reserves are held subject to an interest-bearing commitment. However, an Islamic insurance company and a conventional reinsurance company may agree that a portion of the amounts payable to the reinsurance company remains with the Islamic insurance company and is managed under a Mudarabah or Wakalah investment arrangement. Under such an arrangement, the Islamic insurance company acts as the Mudarib (investment manager) or investment agent, while the reinsurance company acts as the capital provider. Profits are distributed in accordance with the terms of the agreement. The reinsurance company's share of the profit is credited to its account maintained with the Islamic insurance company. The share of profit earned by the Islamic insurance company in return for its investment management activities, conducted independently from the insurance fund, is credited to the account of the investors or shareholders, as applicable.

• Agreements between an participation insurance company and a conventional reinsurance company should be limited to the duration required by necessity.

• Prior to entering into such arrangements, the Islamic insurance company must obtain the approval and endorsement of its Shariah Supervisory Board.

• Arrangements with conventional reinsurance companies should be kept to the minimum extent necessary. The Shariah Supervisory Board is responsible for monitoring and overseeing compliance with this requirement.

• Shariah Treatment of Commissions and Indemnities Paid by Conventional Reinsurance Companies to Islamic Insurance Companies: There is no Shariah prohibition preventing an Islamic insurance company from receiving indemnity payments made by conventional reinsurance companies in respect of covered losses.

• An Islamic insurance company may not receive profit-sharing distributions or profit rebates derived from the residual income of a conventional reinsurance company. However, it may negotiate a reduction in the reinsurance contribution payable to the conventional reinsurance company.

Islamic jurists permit Takaful operators to engage with reinsurance companies to the extent required by necessity, based on the legal maxim stated in Article 21 of the Majalla: Al-darurat tubih al-mahzurat (necessities render prohibited matters permissible).

Accordingly, Takaful operators may utilise conventional reinsurance capacity to manage risks that cannot be fully accommodated by Retakaful providers. For example, if a Retakaful operator is able to provide coverage for only up to 50% of a given risk, the remaining 50% may be reinsured through a conventional reinsurance company.

Functions of Reinsurance

As the scale and complexity of risks across nearly all classes of insurance often exceed the capacity of a single insurer, the transfer and distribution of such exposures among reinsurers constitutes one of the primary purposes of reinsurance. Just as policyholders purchase insurance protection from insurers, insurers obtain reinsurance protection from reinsurers to manage their risk exposures and strengthen their underwriting capacity. In this respect, an underlying insurance contract serves as the fundamental basis for any reinsurance arrangement. The principal functions of reinsurance can be summarised as follows:

1. Enhancing underwriting capacity. Reinsurance enables insurers to expand their underwriting capacity and provide coverage for larger and more complex risks. It also facilitates the geographical diversification of risks while strengthening an insurer's overall capacity and market position.

2. Supporting underwriting strategy. By determining retention levels based on technical expertise, financial strength and anticipated loss experience, insurers can develop and implement more effective underwriting strategies.

3. Expanding market reach. As insurers generally possess more detailed knowledge of the underlying risks than reinsurers, reinsurance allows them to adopt a more flexible underwriting approach, optimise portfolio management and expand their market presence.

4. Providing financial support. Reinsurance contributes to an insurer's financial stability through reinsurance commissions and by sharing claim obligations in proportion to the reinsurer's assumed share of risk. In certain circumstances, reinsurers may also provide advance claim payments within agreed limits, helping insurers manage liquidity and meet their financial obligations.

5. Facilitating knowledge transfer. Reinsurers provide valuable technical expertise and market insight, particularly for newly established insurers. This exchange of knowledge supports the development of underwriting, pricing and risk management capabilities.

6. Supporting tailored coverage solutions. Reinsurance enables insurers to offer specialised coverage, competitive pricing and policy terms that meet the evolving needs of their clients.

7. Stabilising claims experience. By spreading risk across a broader portfolio, reinsurance helps smooth claims fluctuations and ensures that large or catastrophic losses can be absorbed without disrupting claim payments.

8. Contributing to economic development. Through strengthening the resilience and capacity of the insurance sector, reinsurance plays an important role in supporting economic stability and sustainable growth.
