📋 '''Asbestos claims''' are [[Definition:Liability insurance | liability]] and [[Definition:Workers' compensation | workers' compensation]] claims arising from bodily injury — primarily mesothelioma, asbestosis, and lung cancer — caused by exposure to asbestos fibers. For the global insurance industry, asbestos claims represent one of the largest and most enduring [[Definition:Long-tail liability | long-tail loss]] categories in history, with total insured costs estimated in the hundreds of billions of dollars and new claims still emerging decades after peak asbestos usage. These claims have profoundly shaped [[Definition:Reserving | reserving]] practices, [[Definition:Reinsurance | reinsurance]] structures, and [[Definition:Policy wording | policy interpretation]] across multiple jurisdictions.

⚙️ The mechanics of asbestos claims are complicated by extreme [[Definition:Latency period | latency]]: the interval between initial exposure and the manifestation of disease can span 20 to 50 years, meaning policies written in the 1940s through the 1980s are still being triggered by claims filed today. Insurers and [[Definition:Reinsurer | reinsurers]] face complex coverage disputes over which policy years respond, whether [[Definition:Occurrence | occurrence]]- or [[Definition:Claims-made policy | claims-made]]-based triggers apply, and how aggregate [[Definition:Policy limit | limits]] interact across stacked policy towers. In the United States, litigation has driven the bankruptcy of numerous asbestos defendants and the establishment of statutory trusts to compensate claimants. In the UK, landmark rulings — notably the Fairchild and Trigger cases — have shaped how [[Definition:Employers' liability insurance | employers' liability]] policies respond to mesothelioma claims. [[Definition:Lloyd's of London | Lloyd's of London]] created the Equitas vehicle in the 1990s specifically to manage its enormous legacy asbestos and pollution liabilities, and the broader [[Definition:Run-off | run-off]] market owes much of its existence to the challenge of managing these exposures.

🔎 The enduring impact of asbestos claims on the insurance industry cannot be overstated. They catalyzed the widespread adoption of [[Definition:Asbestos exclusion | asbestos exclusions]] in new policies, drove fundamental changes in how insurers establish [[Definition:Incurred but not reported (IBNR) | IBNR reserves]] for long-tail liabilities, and remain a dominant component of [[Definition:Legacy liabilities | legacy portfolios]] held by [[Definition:Run-off company | run-off companies]] and acquired by specialist consolidators such as [[Definition:Enstar Group | Enstar]] and [[Definition:RiverStone International | RiverStone]]. Regulators in the United States, UK, and continental Europe continue to monitor asbestos reserve adequacy closely, given the potential for adverse development. For actuaries, claims managers, and reinsurance professionals, asbestos claims serve as a defining case study in how latent exposures can generate losses that dwarf original underwriting assumptions — a lesson directly relevant to emerging risks like [[Definition:Per- and polyfluoroalkyl substances (PFAS) | PFAS contamination]] and [[Definition:Climate risk | climate liability]].
