⚙️ Casualty insurance operates through a wide spectrum of product lines tailored to different sources of legal exposure. [[Definition:General liability insurance | General liability]] (or public liability) covers bodily injury and property damage arising from business operations or premises. [[Definition:Professional liability insurance | Professional liability]], including [[Definition:Errors and omissions insurance | errors and omissions (E&O)]] and [[Definition:Medical malpractice insurance | medical malpractice]], responds to claims arising from professional services or advice. [[Definition:Workers' compensation insurance | Workers' compensation]] — a statutory form of casualty coverage in many jurisdictions — provides no-fault benefits to employees injured on the job. [[Definition:Product liability insurance | Product liability]], [[Definition:Directors and officers liability insurance (D&O) | directors and officers (D&O)]], [[Definition:Employment practices liability insurance (EPLI) | employment practices liability]], and [[Definition:Cyber insurance | cyber liability]] all fall within the casualty umbrella. These lines share a common characteristic: they are typically [[Definition:Long-tail business | long-tail]] in nature, meaning claims can take years or even decades to fully develop and settle, which introduces significant [[Definition:Reserving | reserving]] complexity and demands sophisticated [[Definition:Actuarial analysis | actuarial analysis]].
🔧 Casualty lines operate on a fundamentally different loss-development timeline than property coverages. Because [[Definition:Claim | claims]] often involve litigation, regulatory proceedings, or medical treatment that unfolds over years or even decades, casualty insurance is classified as [[Definition:Long-tail insurance | long-tail business]]. [[Definition:Reserves | Loss reserves]] must account for extended reporting and settlement periods, requiring sophisticated [[Definition:Actuarial analysis | actuarial techniques]] to estimate ultimate liabilities. The trigger for coverage — whether a policy responds based on [[Definition:Occurrence | occurrence]] during the policy period or on a [[Definition:Claims made | claims-made]] basis — is a critical structural feature that varies by product and jurisdiction. [[Definition:Underwriter | Underwriters]] price casualty risks using [[Definition:Claims experience rating | experience rating]], exposure-based models, and increasingly, [[Definition:Predictive analytics | predictive analytics]] that incorporate litigation trends and regulatory shifts across different legal systems.
