The Johns-Manville asbestos litigation took 12 years to reach settlement and is expected to generate nearly 500,000 claims at a value of over $34 billion. This book describes the taks of forecasting the number, timing, and nature os claims from a set of exposed persons of unknown size. The models will be of use in other product liability cases such as those involving tobacco and breast implants. The volume is written for a broad audience of actuaries, biostatisticans, health scientists, financial analysts, and statisticians.
