What is Reinsurance? - Know the Types And Benefits

As policyholders, we share our risks with insurance companies by buying insurance policies. However, did you wonder what insurers do when the risk becomes too much for them? Well, they reinsure from other insurance companies, and the process is called reinsurance.

Just as policyholders transfer their risks to insurers, insurers also share their risks with other insurance companies to remain financially secure. In India, companies like Bajaj General Insurance often reinsure their risks with giants such as the General Insurance Corporation of India.

So, dive in to explore what is reinsurance, how it works, its types, objectives, and the key benefits it offers.

What Do You Mean by Reinsurance?

Reinsurance is a risk management tool used by insurance companies to protect themselves from significant, unexpected losses. By transferring a portion of their risk to another insurer, the primary insurer can mitigate the financial impact of large-scale claims.

This process of reinsurance in insurance becomes crucial during natural disasters or catastrophic events that trigger multiple major claims simultaneously. For instance, if an insurer issues policies worth ₹100 crore and transfers 40% of this risk to a reinsurer, it only bears ₹60 crore of potential losses while the reinsurer covers ₹40 crore.

Major reinsurance companies for Indian insurance companies are:

1. General Insurance Corporation of India or (GIC Re)

2. Swiss Re

3. Munich Re

How Does Reinsurance Work?

Now that you know what is reinsurance, read the illustration below to understand how reinsurance works.

1. Risk Assessment: The insurance company thoroughly evaluates its risk portfolio and identifies policies that pose risks to it.

2. Choosing the Type of Reinsurance: Once the insurance company evaluates its risk, it decides on the type of reinsurance it would prefer.

3. Conciliating the Reinsurance Agreement: The insurance company reaches out to a reinsurance company, and they negotiate the terms of the reinsurance contract. The parameters generally include coverage, premiums, rate of risk transfer, and claim sharing.

4. Risk Transfer: The insurance company and the reinsurance company finalise their agreement.

5. Monitoring and Adjusting: During the term of reinsurance, both parties monitor the policy and make adjustments if regulatory changes or shifts in market dynamics alter the risk profile.

6. Making Claims: When a policyholder raises a claim, the insurance company processes it to the reinsurer, and the reinsurer disburses its share of the claim amount as per its agreement.

What are the Benefits of Reinsurance?

Reinsurance is an excellent way for insurance companies to manage risks they cannot handle on their own. Read more to learn about the various advantages of reinsurance.

Risk Sharing

Primary insurance companies diversify their risk across different lines of business and geographic areas. This saves them from having to disburse claims in bulk themselves due to a single unforeseen event.

Solvency Margin Compliance

As per IRDAI’s regulations, all insurance companies must maintain a solvency ratio of at least 1.5 (i.e., 150%). Reinsurance plays a massive role in helping primary insurance companies to comply with this law by sharing their liabilities.

Market Expansion

Reinsurance helps to reduce the risk that primary insurance companies face from individual policyholders. This support enables insurers to underwrite high-value projects such as renewable energy parks or airports without exceeding their capital limits.

Financial Stability

Reinsurance provides a safety net for primary insurers by absorbing the financial impact from a significant catastrophic loss. This helps reduce the likelihood of insolvency arising from bulk claim settlements.

Global Expertise

Reinsurers help primary insurers to learn specialised expertise in complex underwriting and risk management.  Primary insurers use this skill to make insurance more efficient by improving the quality of coverage and premium price for general policyholders.

What are the Types of Reinsurance?

After understanding what is reinsurance in insurance, it is time to look at the types available:

Facultative Reinsurance

Facultative reinsurance is a type of reinsurance in which a reinsurer covers the risk of individual policies on a case-by-case basis. The reinsurer has the right to review and accept each risk separately. This process is generally used for insurance of large-scale commercial or infrastructure coverage in India.

Treaty Reinsurance

This is another form of reinsurance in which the reinsurer covers a portfolio of risks or policies under a single contract or treaty. This is a type of general, ongoing risk-sharing for a specific portfolio, such as all fire, health, or motor risks.

Proportional Reinsurance

This is a type of reinsurance in which the primary insurer and the reinsurer share premiums and claims from policyholders at a fixed ratio. For example, a reinsurer agrees to share 40% of both claims and premiums. 

Non-Proportional Reinsurance

This is a type of reinsurance in which the reinsurer pays only when the loss from claims exceeds a pre-agreed threshold. The Non-Proportional reinsurance was created to manage high-severity events, such as natural disasters. This helps reduce the insurer's financial burden in extreme scenarios.

What is The Effect of Reinsurance on Policyholders?

Reinsurance has an indirect effect on general policyholders. Let us know how.

1. Increased Certainty in Claims: Even after catastrophic events, insurers backed by reinsurance can fulfil claims on time, as reinsurance helps to reduce the pressure of disbursing claims.

2. Stable Premiums: Reinsurance helps primary insurance companies avoid severe losses. This helps to avoid sharp premium hikes, benefiting policyholders.

3. Enhanced Product Innovation: With reinsurance, primary insurers have the space to launch new insurance policy variants and handle the pressure of upcoming liabilities.

4. Trust in Insurer Reliability: You can trust the insurance companies that actively participate in reinsurance, as there is a lower risk of insolvency for them. You can also rest assured of stability in premium prices.
