Insurance policies have covered the negative effects of asbestos for both workers and the companies embroiled in the problem. Asbestos insurance has not been embraced by the insurance companies. They have sought and fought to have the concept of "single occurrence" applicable to meet their designs .Recently, the companies lost in Wisconsin in the United States in their attempt to implement their definition of "occurrence." The Wisconsin Supreme Court ruled that each time a plaintiff sues is a separate occurrence. The total bill for asbestos continues to impact the various companies. It will be an ongoing matter unless legislation or courts decide otherwise. A major factor in this matter is not only the attitude of governments and companies but the very nature of asbestos. The effects of asbestos exposure may not be immediately obvious to an individual. Mesothelioma has a latency period of between 15 to 50 years. As a result, people affect in the past 20 years may now only be seeking redress through lawyers and their company policies.
