Contribution In Insurance – Demystifying the Secrets & Implications 2023

Posted by

In recent times, lots of people have been searching to know what contribution in insurance is really all about, as it has been misunderstood by both insurers and policyholders for some time.

Contributions play a crucial role in determining how multiple insurance insurance policies interact when covering a certain shared risk. Before we start, let’s define some key terminologies relating to Contribution in Insurance, so we can flow easily.

Key Terminologies Around Contribution In Insurance

The following terminologies will help you understand how contribution in insurance works, as well as foster better communication with your insurers:

  • Policyholder/Insured: This is you or the entity that purchased the insurance policy.
  • Premium: This is the amount you are to pay to the insurance company for your coverage.
  • Insurer/Insurance Company: The entity providing insurance coverage in exchange for premiums.
  • Coverage: The protection and benefits outlined in the insurance policy.
  • Deductible: The amount the policyholder must pay out of pocket before the insurance coverage kicks in.
  • Contribution: The sharing of loss among multiple insurance policies.

What is Contribution In Insurance?

In the world of insurance, we will simply define contribution as the concept of proportionally sharing the burden of a certain loss among multiple insurance policies that cover the same risk.

From the above definition, I believe you can sense that contribution shields you the policyholder, as it will ensure you don’t receive more than your fair share of compensation in the event of a claim. This ensures fairness and prevents you from profiting unduly from an unfortunate and unforeseen event.

The Different Types of Contribution

In Insurance, there are 2 basic types of contributions, and they we have:

  • Pro-rata Contribution
  • Excess Contribution

#1. Pro-rata Contribution:

Basically, in Pro-rata contribution, the loss is distributed proportionally among the various insurance policies covering the same risk.

From our experience, we observed that this method usually comes into play when policies have the same terms and conditions. See how it works; the amount that was paid by each insurer for the loss is proportional to the limit of liability specified in their respective insurance policies.

Let me give you a simple example:

Consider a scenario where a Building valued at $500,000 is insured by Insurer X for $250,000 and Insurer Y for $150,000. If the building incurs a loss of $100,000, Insurer X would contribute 50% ($250,000 / $450,000) of the loss, amounting to $50,000, while Insurer Y would contribute 30% ($150,000 / $450,000), totaling $30,000.

#2. Excess Contribution

In this type of insurance contribution, multiple insurance policies cover the same claim or risk, and one insurer ends up paying more than their fair share of the claim.

I am sure you can predict that the other insurers will have to reimburse the first insurer for the excess amount that they paid.

Here are some reasons why this happens:

  • When the policies have overlapping coverage.

Overlapping coverage simply means that both insurance policies cover the same event or loss.

  • When the policies have different excess amounts.

An excess is that amount of money that You, the policyholder have to pay out of pocket before the insurance company starts to pay their part. So, this implies that If one policy has a lower excess than the other, that insurer will end up paying more of the claim.

  • Also when the policies have different limits of liability.

Briefly, a limit of liability is the maximum amount that an insurance company will pay for a claim. If one policy has a lower limit of liability than the other, that insurer will reach its limit first and the other insurer will have to pay the rest of the claim. Do you get it now?

Now, this is what you need to do to avoid excess contributions.

First, it is important that you make sure that your insurance policies do not overlap and that you understand the terms and conditions of your policies, including the excess amounts and limits of liability, as we explained earlier.

On the other hand, you may also want to consider purchasing excess contribution insurance, as it will reimburse you for any excess contributions that you have to pay.

Principle of Indemnity in Contribution

You can’t really talk about contribution without mentioning the principle of indemnity. This is where insurance seeks to restore you the insured, to the same financial position as before the loss occurred. If you can clearly understand this principle, playing around with contribution in insurance becomes easy.

Real-World Applications of Contribution in Insurance:

#1. Contribution to Property Insurance:

You know when it comes to property insurance, the risk of damage or loss is ever-present and likely inevitable, so contribution comes in helpful. When you have multiple policies covering the same property for example:

  • Homeowners’ insurance
  • Flood insurance, and
  • Earthquake insurance, then contribution must come into play, so it can necessitate the fair distribution of liability.

#2. Contribution to Liability Insurance:

Here, Contribution comes in when you the policyholder have coverage under multiple liability policies. So in cases of personal injury or property damage, the concept of contribution will ensure that the responsibility of covering the insured is shared appropriately.

#3. Contribution to Commercial Insurance:

If you run a business, you will attest to the fact that most businesses often hold various insurance policies to mitigate diverse risks. Contribution now becomes helpful in commercial insurance scenarios, where overlapping coverage is common.

We advise Insurers to navigate and clearly understand the principles of contribution to determine their respective obligations in case of a claim.

#4. Contribution in Life Insurance:

We all know that Life insurance isn’t like property insurance, where physical assets are at the forefront. In life insurance, we are primarily dealing with human lives and financial protection.

So like other insurance policies, contribution in life insurance would come into play when a policyholder holds multiple life insurance policies. The main objective is to prevent you from over-insuring your life and, in turn, profiting from multiple policies in the event of death.

You also need to know that while contribution is designed to bring clarity to the distribution of loss, disputes can arise. Some of the common challenges include:

  • Disagreements on the valuation of the loss
  • Differences in policy terms, and
  • Varying interpretations of the contribution principle.

Now in order to address these contribution disputes, there need to be provisions for alternative dispute resolution mechanisms, such as arbitration or mediation. These mechanisms over time aim to provide a faster and more cost-effective resolution compared to traditional methods

Some Practical Implications of Contribution in Insurance

  • Coordination of Policies:

As an individual or as one that runs a business hiking multiple insurance policies, it’s very crucial for you to understand the implications of contribution as it has a lot to do with your policy coordination.

This will really save you a lot of stress, as you will now have a well-coordinated and seamless collaboration with your insurers.

  • Subrogation and Contribution:

Subrogation is simply the right of an insurer to pursue a third party that is responsible for a loss, and this case most times intersects with the contribution.

Insurers mostly seek contributions from other parties to help the overall cost of a claim, emphasizing the interconnected nature of these principles.

The Importance of Contribution to Insurance

The following are the importance of contribution in Insurance:

#1. Fair Distribution of Risk:

Contribution helps to ensure that the financial burden of a loss is equitably distributed among the insurers. This has over time helped to prevent any single insurer from bearing the entire responsibility and promotes a sense of shared risk within the industry.

#2. Helps to Avoid Over-Insurance:

Contribution also helps to act as a deterrent against over-insuring a property or asset. If contribution is not in place, you the policyholder might be inclined to secure multiple policies for the same risk, potentially gaining more than the actual loss in the event of a claim, which is not good.

#3. It Encourages Sound Underwriting Practices:

Most of these Insurers that are motivated by the concept of contribution, are usually prompted to engage in serious underwriting practices. This ensures that the pricing of policies is perfect, and the risks involved are thoroughly assessed, which at large contributes to the overall stability of the insurance industry.

#4. Efficient Claim Settlements:

Contribution ensures a smoother and more efficient way to settle the claims process. As the guidelines on how the loss is to be shared have been clearly stated, the insurers involved can streamline the resolution process, minimizing disputes and speeding up compensation to the policyholder.
