<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>⚠️ &#039;&#039;&#039;Mass tort&#039;&#039;&#039; is a civil action in which numerous plaintiffs allege injury or harm caused by a single product, substance, or course of conduct — and in the insurance world, mass torts represent some of the most consequential and financially devastating [[Definition:Loss | loss]] events that [[Definition:Liability insurance | liability insurers]] face. Asbestos litigation, opioid lawsuits, and per- and polyfluoroalkyl substances (PFAS) claims are prominent examples where [[Definition:Insurance carrier | carriers]] have been drawn into protracted, multi-billion-dollar disputes stretching across decades and policy periods.<br /> <br /> 🔧 From an insurance standpoint, mass torts create extraordinary complexity in [[Definition:Claims management | claims handling]] and [[Definition:Reserving | reserving]]. A single mass tort can trigger coverage under hundreds of [[Definition:Insurance policy | policies]] issued by dozens of insurers over many years, raising difficult questions about which policies respond, how [[Definition:Policy trigger | policy triggers]] apply, and whether [[Definition:Occurrence | occurrence]]-based or [[Definition:Claims-made policy | claims-made]] wording governs. [[Definition:Actuarial science | Actuaries]] struggle to estimate ultimate liabilities because the volume of claimants, severity of individual awards, and duration of litigation remain deeply uncertain. Insurers and [[Definition:Reinsurer | reinsurers]] often establish dedicated mass tort units and engage specialized [[Definition:Defense counsel | defense counsel]] to manage these exposures.<br /> <br /> 💰 The financial ripple effects of mass torts extend well beyond individual claim payments. They can erode an insurer&#039;s [[Definition:Surplus | surplus]], trigger [[Definition:Reinsurance recovery | reinsurance recoveries]] across multiple [[Definition:Treaty reinsurance | treaty]] layers, and reshape entire lines of business — as the asbestos crisis did when it effectively rewrote how [[Definition:Commercial general liability (CGL) | commercial general liability]] policies are drafted and interpreted. For [[Definition:Underwriter | underwriters]], emerging mass tort risks like PFAS, climate litigation, and [[Definition:Social inflation | social inflation]] trends demand forward-looking exposure analysis that goes far beyond historical loss data. The ability to identify latent mass tort exposures before they fully materialize has become a defining skill for sophisticated [[Definition:Risk management | risk management]] teams.<br /> <br /> &#039;&#039;&#039;Related concepts&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Liability insurance]]<br /> * [[Definition:Asbestos liability]]<br /> * [[Definition:Social inflation]]<br /> * [[Definition:Reserving]]<br /> * [[Definition:Commercial general liability (CGL)]]<br /> * [[Definition:Latent claim]]<br /> {{Div col end}}</div>
