Understanding reinsurance in Australia

• Reinsurance is a crucial component of the insurance market and enables insurance companies to share and minimise exposure to risks
• As a global company based in Australia, QBE is in a unique position as an Australian-based insurer with its own reinsurance division
• By understanding the reinsurance arrangements of your insurer, you can be more confident in their ability to deliver in the event of large-scale claims

Just as businesses and individuals take out insurance to cover themselves and their interests in the event of an incident, so too do insurance companies. Reinsurance – insurance for insurance companies – is commonplace in the insurance industry and enables insurers to share their risk with other parties.

As Senior Underwriting Manager for Global Reinsurance Underwriting Operations, Sigi Dobry, explains, “reinsurance is an important part of the global insurance market. It provides stability and enables the insurer to take on larger, more complex or non-standard risks.”

While reinsurance comes at a cost for insurers – with Dobry sharing that it is not unusual for an insurer to spend more than a fifth of their premium income on reinsurance – this spend is essential.

“Sharing the risk with a reinsurer allows insurers to reduce the amount of capital that may be reserved to cover the claims, which means more capital is available to support broader business operations,” says Dobry.

With reinsurance playing such a significant role in the insurance market, it’s important as brokers and business owners to understand the reinsurance arrangements of your insurer. Armed with this knowledge, you can be more confident that you’re offering and buying products from an insurer that is properly covered and has sufficient funds to pay large-scale claims.

Additionally, the insurers’ reinsurance purchases are heavily supervised by the Australian Prudential Regulation Authority (APRA), providing another level of certainty and confidence for brokers and business owners.

How reinsurance works: treaty vs facultative

Treaty reinsurance – sometimes called obligatory reinsurance – is when the reinsurer and the reinsured agree to share their risk across a whole portfolio of insurance businesses.

“A framework is agreed, and every type of business that falls within that framework will be covered by the reinsurer,” says Dobry.

“This works well, as you can have thousands upon thousands of policies that you don’t have to assess individually, and won’t be rejected, as long as they fit the criteria.”

Facultative insurance is the opposite and is used when risks fall outside of the treaty reinsurance.

With facultative insurance, the reinsurer has the choice to either accept or reject individual policies, based on the risk they present.

“If it has unique risks that don’t really fit into a box, you would go down the facultative path; if it fits into the box, you go down the treaty path,” says Dobry.

How reinsurance works: proportional vs non-proportional

Once risks have been reinsured via treaty or facultative, they can be proportionally or non-proportionally reinsured.

This effectively determines how the risk is shared – whether it’s split, for example, 50/50 (proportional), or whether there’s a limit to the risk (non-proportional).

“Proportional means the insurer and reinsurer agree how the risk is shared,” says Dobry. 

“Non-proportional means the insurer will keep and pay claims up to a certain value, but when a claim reaches a certain amount, the reinsurer will step in and take over.

“Catastrophic weather events can result in billions of dollars of damage to property across communities. An insurer might purchase non-proportional catastrophe reinsurance so that after insurance claims for an event surpass a certain amount, the reinsurer will cover the remainder of claims costs up to the amount of coverage that was pre-agreed and purchased,” says Dobry.

How reinsurance works: retrocession

Retrocession is when a reinsurance company also buys reinsurance, which enables it to further share its risk. The reinsurance company will also decide how to manage that risk – whether it’s proportional or non-proportional – in exactly the same way as described above.

What is reinsurance commonly used for?

A common assumption is that reinsurance is only purchased to lessen the risk associated with catastrophic events. While reinsurance does commonly provide protection for such events, it also offers protection from the frequency of individual losses and the occasional large losses, such as a fire at a large building or a significant liability claim.

The importance of reinsurance expertise

QBE has a unique position in the insurance industry, as an Australian based insurer and reinsurer. QBE’s dedicated in-house reinsurance business provides reinsurance to internal QBE operations, while QBE Re – a separate division – offers reinsurance to other insurance companies externally.

Our experienced teams of actuaries, catastrophe modelers and other specialists, model scenarios to help understand the things that could go wrong – which in essence is what reinsurance aims to protect against.

“This can be difficult, as the world is changing and what’s happened before doesn’t necessarily provide all of the clues,” says Dobry.

For example, Cyclone Tracey made landfall in Darwin in December 1974, the original estimated insured losses added up to approximately AUD$200 million. If the very same cyclone occurred today, the financial impact would be significantly different due to shifts in population, inflation, changes in building codes and of course the amount of insurance purchased by the public. Also, the impact of changes in the climate could alter the paths and intensity of similar storms in the future. The insured losses from Cyclone Tracey today are estimated to exceed AUD$5 billion¹.

“While it’s challenging to cover all the possibilities, here at QBE, we’re constantly working on scenarios to ensure we’re giving the very best service to our reinsurance customers, both internally and externally.”
