&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;📋 &amp;#039;&amp;#039;&amp;#039;Asbestos&amp;#039;&amp;#039;&amp;#039; is a group of naturally occurring fibrous minerals that, in the insurance industry, has become synonymous with one of the longest-running and most financially devastating [[Definition:Mass tort | mass tort]] liabilities in history. Decades of widespread use in construction, shipbuilding, and manufacturing — combined with the discovery that inhaling asbestos fibers causes [[Definition:Mesothelioma | mesothelioma]], lung cancer, and asbestosis — generated an enormous wave of [[Definition:Bodily injury | bodily injury]] claims against manufacturers, building owners, and employers, with their [[Definition:General liability insurance | general liability]] and [[Definition:Workers&amp;#039; compensation insurance | workers&amp;#039; compensation]] insurers ultimately absorbing much of the financial impact. The long [[Definition:Latency period | latency period]] between exposure and disease onset, sometimes exceeding 30 years, created extraordinary challenges in allocating losses across multiple policy years and successive carriers.&lt;br /&gt;
&lt;br /&gt;
⚙️ When asbestos-related claims began flooding courts in the late 20th century, insurers faced a host of coverage disputes: which policy years were triggered, whether [[Definition:Occurrence | occurrence]]-based or [[Definition:Claims-made policy | claims-made]] wordings applied, how [[Definition:Policy limits | limits]] stacked across consecutive years, and whether [[Definition:Pollution exclusion | pollution exclusions]] or other [[Definition:Exclusion | exclusions]] relieved the insurer of liability. Landmark court decisions varied by jurisdiction, producing a patchwork of legal standards. Carriers established dedicated [[Definition:Asbestos and environmental (A&amp;amp;E) | A&amp;amp;E]] reserve units to model exposure, and [[Definition:Reinsurance | reinsurers]] — particularly at [[Definition:Lloyd&amp;#039;s of London | Lloyd&amp;#039;s of London]] — faced existential stress as [[Definition:Incurred but not reported (IBNR) | IBNR]] estimates ballooned. The [[Definition:Actuarial | actuarial]] complexity of projecting future claim filings, plaintiff survival rates, and settlement values pushed insurers to develop specialized [[Definition:Reserving | reserving]] methodologies that remain in use today.&lt;br /&gt;
&lt;br /&gt;
💡 Asbestos reshaped the insurance industry&amp;#039;s approach to long-tail [[Definition:Liability insurance | liability]] in fundamental ways. It drove the adoption of more precise [[Definition:Policy language | policy language]], absolute [[Definition:Pollution exclusion | pollution exclusions]], and [[Definition:Aggregate limit | aggregate caps]] designed to prevent open-ended exposure. Regulators now require carriers to report asbestos reserves separately, and [[Definition:Rating agency | rating agencies]] scrutinize these liabilities closely when assessing an insurer&amp;#039;s financial strength. Billions of dollars remain in outstanding reserves industry-wide, and new claims continue to emerge — albeit at a declining rate — ensuring that asbestos remains a live topic in [[Definition:Loss reserving | loss reserving]] discussions, [[Definition:Run-off | run-off]] portfolio transactions, and [[Definition:Legacy liability | legacy liability]] management strategies. The experience also serves as a cautionary benchmark whenever the industry confronts emerging long-tail risks such as [[Definition:Per- and polyfluoroalkyl substances (PFAS) | PFAS]] contamination or [[Definition:Climate change risk | climate change]].&lt;br /&gt;
