premiums were more than outlays by 5.2%.
The Operating Ratio = Combined Ratio after Dividends – Investment Yield
Operating Ratio = 94.8 – 10.6 = 84.2
With the operating ratio < 100, the numbers indicate that the loss ratios coupled with
relatively strong investment yields generated profitability for the P&C industry as a
whole for the year.
Uncertain loss ratios, high expense ratios, the need to pay dividends, a lack of flexibility
to adjust premiums and uncertain investment yields all indicate the need for large policy
surpluses, which the industry currently has (equal to about 36.2% of assets).
Many low frequency, high severity losses occurred in the 1990s and 2000s including
many natural disasters such as the strong El Nino, the many severe hurricanes, including
Katrina, earthquakes, tsunamis, cyclones, tornadoes and flooding, and some manmade
disasters such as asbestos and tobacco liability claims and the attack on the World Trade
Center. These have generated abnormally large losses. Some have estimated that the
dollar cost of the terrorist attacks was as high as $40 billion. The federal government
now has a terrorism insurance program. The government is responsible for 90% of
insurance industry losses that arise from a terrorist incident if the losses exceed a certain
amount. Each insurer would have to pay 15% of its commercial P&C premiums.
Nevertheless the cost to insure high probability targets remains expensive.

The text mentions the court decision that allowed Halliburton to resolve its asbestos
liability (asbestos causes lung cancer and workers and community members in production
sites such as Libby, Montana have suffered decades of higher cancer rates) by
bankrupting one of its subsidiaries. This could help keep liability insurance down but it
may set a disturbing precedent and may encourage other firms to engage in unethical
behavior because the potential penalties may now be perceived as lower.
Insurance companies can attempt to share risks by buying insurance from other insurance
companies. This growing practice is called reinsurance. About 10% of all insurance
contracts world wide are ‘reinsured.’ P&C insurers engage in reinsurance to a greater
extent than life insurers due to the greater unpredictability of P&C claims. Foreign
insurance firms write about 75% of the reinsurance contracts used by U.S. insurers.
Catastrophe bonds are a unique form of reinsurance. Different bonds may have different
structures but the basic idea is that the bond’s principal and interest are reduced if a given
catastrophe occurs. The reduction in the bond issuer’s payments then can offset the
