What is Reinsurance?

4 min read

Article Image

Everybody knows the principles of insurance. You probably have subscribed insurance policies for your flat, your car, personal liability and more. In many countries this is even mandatory.Insurance offers you protection against uncertain damage for a fixed premium. Insurers must therefore be able to absorb these damages and shocks, and to do so, they diversify their portfolio of contracts as much as possible. However, they transfer part of their risks to third party companies: reinsurers.Therefore one may wonder, why do insurers need reinsurance? Isn't it their role to analyse risk and provide protection at a fair pricing against it?

The need for reinsurance

One way to conceptualise reinsurance is to see insurers as a first layer of protection, against single risks. However, this is still a risky business, with for example:
• Accumulation of risks on large natural catastrophes, or terrorist events
• Large risks, which are difficult to diversify (e.g. factories, powerplant, satellites)
• Emerging risks (e.g. cyber)
A concrete example could be a hurricane on the east coast of the US, causing billions of dollars in damage. If an insurer holds too large a portion of these damages, it could adversely impact its financial solvency.Insurers therefore need a second layer of diversification to de-risk their business, to protect and optimise their capital. This is where reinsurers enter into action! Reinsurers are able to provide this second layer of protection because they are more diversified: they operate in many markets and regions. The reinsurance industry is therefore by nature a global industry. Reinsurers control their own risk exposures and capital, and can protect themselves through retrocession (third and last layer of protection and diversification) by transferring risks to other reinsurance players.

An unknown but significant industry

Insurers are well known companies given the B2C nature of their activity. They generate globally more than 5 trillion dollars every year in revenue and employ millions of people (150,000 employees in France alone).On the other hand, reinsurers are less known by the general public as they only operate on a B2B basis. The beginning of reinsurance can be traced back to at least the 14th century, when it was used for marine and fire insurance! It is now covering all aspects and lines of business of the modern insurance market.The industry generates 300 billion dollars in revenue every year, which can seem modest compared to the insurance industry, however when you look at the number of players in the industry this is significant. The largest reinsurers make tens of billions of dollars in revenue. In addition to providing reinsurance capacity, reinsurers also generate revenue by supporting cedents (insurers) services in risk, capital and solvency management.

The functioning of the reinsurance industry

Reinsurers generate revenue by taking risks from insurers against a premium, like insurers do with their clients. However transactions are much larger and complex than the usual insurance contracts.There are many types of transactions for insurers and reinsurers to transfer risks. These transactions can be quite complex, are very often tailor-made and involve a lot of players. Several dozen reinsurers can take smaller or bigger parts of a single treaty, negotiating the price, the capacity provided and the wording of the contract.Reinsurance brokers support insurers throughout the process of making transactions, from advising them before the transaction on the structure and amount to be transferred, to negotiating terms and closing the deal. They charge insurers commission on premiums ceded to reinsurers. The actual process to renegotiate transactions (for most of the reinsurance market) is a yearly process which can take up to 4 months. It is a very resource intensive process and has not changed in decades. There was, until recently, no other options available to perform such transactions, and no other options to improve the process. This is what we are changing at Bifröst.


Reinsurance, despite not being well-known, plays a significant role in the stability of the insurance market, and more widely the global economy. At Bifröst, we are convinced that reinsurance market participants (insurers, reinsurers, brokers) could work more efficiently, using new technologies and AI, and this is what we are bringing to the industry.Our solution, a decision support tool for insurers, brokers and reinsurers, enables them to manage their end-to-end renewal process more efficiently than is currently possible. It gives their teams the power and the ability to:
• Take the best decisions backed by data
• Track and report on the placement situation, with a global view on their portfolio
• Optimise their reinsurance processes
Reinsurance teams remain in charge of taking the final decision, but with the power of AI!

The types of Reinsurance

Blog types of reinsurance

4 min read

In our previous article we covered the concept of reinsurance and its different uses. Overall, reinsurance is insurance for insurance companies.
You might wonder — is there a different type of reinsurance for each need? Yes, almost! In this article we will focus on the conventional and most-used types of reinsurance.

Facultative Reinsurance vs Treaty Reinsurance

The first recorded reinsurance contract (circa 1370) was about insuring a cargo ship during its “voyage”. An underwriter decided to ask another party to reinsure part of the journey between two specific locations. This highlights the concept of facultative reinsurance: a reinsurer accepts (or not) an individual risk laid out by an insurer. As it covers large individual risks (gas plants, offshore energy platforms, etc.), facultative reinsurance is tailor-made and the structure is adapted to it. In some cases, it can also be a defined package of risks.The second type of reinsurance is treaty reinsurance. For this type of reinsurance, the insurer transfers the entire book of a business line (e.g. all motor risks). The reinsurer cannot decline any policies from the transferred book — it must accept all of them or none! The cover period of a treaty often lasts for one year and is renewed every year. Usually, non-life insurers have one treaty for each of the following risks: motor, fire and CAT.

Proportional vs. Non-proportional Structures

Because of different needs, the way how risks are transferred to reinsurers varies between different contracts. Fortunately, for reinsurance structures, there are two categories: proportional and non-proportional.A/ Proportional: proportionally shared losses and premiumsThe most common type of proportional treaty is called quota-share. This treaty is a type of pro-rata reinsurance where the insurer cedes, in the same proportion, premium and losses to reinsurers. In return for the administrative tasks and acquisition costs of the insurer, the reinsurers pay a reinsurance commission to the insurer. An annual loss limit paid by each reinsurer may be specified.A quota-share treaty is mainly used to launch new lines of business (or new insurance companies!) or to satisfy solvency requirements. For example, insurtech company Lemonade, underwrites quota-share treaties to “retain a limited share of exposure”.Proportional treaties are not always as simple as quota-share treaties. Another common proportional treaty is: surplus. The proportional rate is estimated in excess of a retention line and depends on the risk sum insured.This type of treaty allows the insurer to write larger risks and diversify its portfolio without fully retaining the risk.B/ Non-proportional: providing covers against specific eventsThe second main category is: non-proportional treaties. There is no proportionality between the premium paid by the insurer and the losses ceded. The first type of non-proportional treaty is excess of loss. It shares similarities with the surplus, but the ceded losses and premium are not related. The reinsurer compensates losses of the insurer exceeding and in deduction of a retention amount. There is also a limit for which the exceeding amount will be once again charged to the insurer. Hence, the reinsurer pays a loss between a threshold and a limit. This type of treaty is mainly defined “per risk” (fire, motor, etc.) or “per event” (windstorm, hail, etc.). Such treaties are used by insurers to protect themselves against major events, such as natural catastrophes.Last but not least: stop-loss treaties. The difference with excess of loss lies in the loss aggregation. Stop-loss is what we call an annual treaty as it aggregates all the losses for a given line of business (or multiple lines of business) during a year. Also, deductibles and limits are given in percentage of loss ratio (ratio between losses and premium). The stop-loss allows insurers to be protected in the event of a poor year in terms of event frequency and/or intensity. For example a multi-line stop-loss treaty will be used to cover all losses negatively impacting the loss ratio from a given percentage.


As the need for reinsurance can greatly vary for every insurer and line of business, different types of reinsurance have been created to protect against event intensity or frequency, per risk or annually, etc. Insurers usually combine different types of reinsurance to be efficiently covered against unexpected events.Bifröst supports all types of structures to enable our clients to efficiently manage their reinsurance treaties all in one place!
