The term Bermuda Form refers to various types of insurance policies. In the 1980s, American companies found it increasingly difficult to buy large amounts of casualty (liability) insurance, partly because American courts interpreted policies in ways which gave coverage to policyholders which was wider than the insurers had anticipated, causing insurers large losses particularly in relation to asbestos and pollution. To meet the needs of corporate insurance buyers, new insurance companies were set up in Bermuda, notably ACE, XL, and Starr Excess Casualty. Each of these insurers produced its own standard-form policy (which has been revised and re-issued over the years), and collectively these policies are loosely described as the "Bermuda Form".
