Liability insurance provides efficient protection against this significant low-frequency, high-severity risk. In the US, the average cost of commercial liability insurance was about 0.2% of revenues in 2008. The average cost of liability insurance is lower in other countries. Worldwide liability insurance premiums In 2008, businesses spent approximately USD 142bn on liability insurance. were approximately USD 142bn in 2008. This is about 25% of the premiums corporations spent on insurance and slightly less than 9% of the global non-life market premium volume of USD 1 585bn. The developed economies account for roughly 95% of commercial liability premiums. The United States, which is by far the largest market, generates 54% of premiums worldwide. The demand for commercial liability insurance in the US is driven by the size of the economy and the sheer volume of lawsuits that are filed in the country. Liability insurance is growing faster The amount spent on liability insurance continues to expand rapidly, exceeding than world GDP. the overall growth of world GDP, due to increasing litigation in almost all regions, rising healthcare costs and the overall increase in damages awarded to plaintiffs.

As a result, the market is more concentrated than other commercial lines markets. The unique aspects of liability insurance The following characteristics distinguish liability insurance from other lines: pose challenges for the industry. ̤ Liability insurance may cover unknown and unexpected risks. New emerging risks can lead to significant losses that are the result of the interaction of tech- nological innovation and changes in the social and legal environment. ̤ The long-tail nature of liability risks results in a higher exposure to inflation, social claims escalation and investment risks. Dynamics in the liability system can create surprise exposures and unexpected changes in the number of claims and claims costs, which were not considered at the time of underwriting the policy. ̤ Over the long run, the profitability of liability insurance has been insufficient. The current profitability is low The industry is currently in a phase of a rapidly decreasing profitability, especially and rapidly declining. in the US. Rates and conditions have been weakening since 2004. Results have been boosted by massive reserves releases and the market has not yet adjusted to the current low-yield environment. Swiss Re, sigma No 5/2009 3 Executive summary Insurers must actively maintain control How can insurers and their clients respond to these challenges? Insurance buyers over exposures and profitability. need to include liability risks in an integrated risk management process. Risk assessment and mitigation play an important role in reducing the overall cost of risk and keeping certain risks insurable. Insurers must better understand and monitor the drivers of liability claims costs and then reflect this in the actuarial models. Insurers must also pay closer attention to wording and policy language in order to manage their exposure to liability risks that are rapidly changing. Finally, the underwriting process must at all times remain focused on maintaining control over exposures and underlying profitability. 4 Swiss Re, sigma No 5/2009 Introduction: characteristics of liability insurance Third party liability insurance is basically Third party liability insurance is usually an ”all-perils” insurance.

The insurance of liability risks can be The insurance of liability risks is a relatively new line of business compared to traced back to the early 19th century. marine, fire or life insurance. It has its roots in the industrialisation of the early 19th century. Interestingly, the introduction of third party liability insurance was heavily disputed among scholars and politicians. While the proponents empha- sised the compensation of innocent victims, the opponents perceived the insurance of “negligence” as frivolous. Today, the concept of insurance is not contest- ed anymore. Moreover, current tort law and compensation levels would not be possible without a well organised liability insurance system.

Because the insurance policy. the trigger events are usually not restricted and because the claim is only defined by the size of the cover and not the value of an insured object, liability claims are much more dependent on changes in the risk landscape.1 While the majority of losses are small high-frequency losses, high-severity events occur. Since large companies tend to buy policies with high deductibles, claims tend to be larger. 1 For a discussion of uncertainty associated with all-perils policies, see Kunreuther, Howard and Pauly, Mark (2004), What You Don’t Know Can Hurt You: Terrorism Losses and All Perils Insurance.
