🏗️ '''Property and casualty insurer''' — known in many markets outside North America as a general insurer or non-life insurer — is a company that underwrites [[Definition:Insurance policy | insurance policies]] covering damage to physical assets and legal [[Definition:Liability insurance | liability]] exposures, as distinct from [[Definition:Life insurance | life insurers]] and [[Definition:Health insurance | health insurers]] whose products center on mortality, longevity, and medical costs. The property and casualty (P&C) sector encompasses a vast range of lines, from [[Definition:Homeowners insurance | homeowners]] and [[Definition:Motor insurance | motor insurance]] for individuals to [[Definition:Commercial property insurance | commercial property]], [[Definition:General liability insurance | general liability]], [[Definition:Workers' compensation insurance | workers' compensation]], [[Definition:Marine insurance | marine]], [[Definition:Professional liability insurance | professional liability]], and [[Definition:Cyber insurance | cyber coverage]] for businesses.

⚙️ P&C insurers collect [[Definition:Premium | premiums]] and invest them — a pool known as the [[Definition:Float | float]] — while reserving for future [[Definition:Claims | claims]]. Because many P&C lines are short-tail (claims are reported and settled relatively quickly), the investment strategy tends to be more conservative than in life insurance, emphasizing fixed-income securities, though the float can still be a significant source of earnings. Underwriting performance is measured through the [[Definition:Combined ratio | combined ratio]]: a ratio below 100% indicates an [[Definition:Underwriting profit | underwriting profit]], while a ratio above 100% means the insurer is relying on investment returns to achieve overall profitability. Regulatory and accounting treatment of P&C insurers varies considerably around the world. In the United States, P&C carriers file statutory financial statements under [[Definition:Statutory accounting principles (SAP) | SAP]] and are subject to [[Definition:Risk-based capital (RBC) | risk-based capital]] requirements administered by state regulators coordinated through the [[Definition:National Association of Insurance Commissioners (NAIC) | NAIC]]. European non-life insurers operate under the [[Definition:Solvency II | Solvency II]] capital framework, while markets like China apply [[Definition:C-ROSS | C-ROSS]] and Japan relies on its own solvency margin standards. The emergence of [[Definition:IFRS 17 | IFRS 17]] has also reshaped financial reporting for P&C entities in adopting jurisdictions, introducing the [[Definition:Premium allocation approach (PAA) | premium allocation approach]] as a simplified measurement model for short-duration contracts.

🌍 Property and casualty insurers occupy a foundational role in the global economy, enabling commerce by absorbing risks that businesses and individuals cannot efficiently retain. The sector's health is closely tied to [[Definition:Catastrophe | catastrophe]] exposure — natural disasters such as hurricanes, earthquakes, and floods can produce industry-wide losses that reshape pricing cycles, trigger [[Definition:Hard market | hard markets]], and test the strength of [[Definition:Reinsurance | reinsurance]] programs. In recent years, P&C insurers have faced rapid evolution driven by [[Definition:Climate risk | climate change]], the growth of [[Definition:Cyber insurance | cyber risk]], and the entry of [[Definition:Insurtech | insurtech]] competitors offering digital-first distribution and data-driven underwriting. Some of the world's largest and most recognized insurance organizations — including [[Definition:Allianz | Allianz]], [[Definition:AIG | AIG]], [[Definition:Tokio Marine | Tokio Marine]], and [[Definition:Zurich Insurance Group | Zurich]] — derive substantial portions of their business from P&C operations, underscoring the segment's scale and strategic importance.
