<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>📐 &#039;&#039;&#039;Aggregation management&#039;&#039;&#039; is the discipline within [[Definition:Insurance carrier | insurance]] and [[Definition:Reinsurance | reinsurance]] organizations that identifies, measures, and controls the accumulation of risk exposures that could produce correlated losses from a single event or common cause. A hurricane making landfall, a widespread [[Definition:Cyber insurance | cyber]] attack, or a systemic legal ruling can trigger thousands of claims simultaneously across policies that appear unrelated when underwritten individually. Aggregation management ensures that the total potential payout from such scenarios stays within the organization&#039;s [[Definition:Risk appetite | risk appetite]] and available [[Definition:Capital | capital]].<br /> <br /> 🗺️ Practitioners rely on a combination of [[Definition:Catastrophe modeling | catastrophe models]], [[Definition:Geospatial analytics | geospatial analytics]], and internal exposure databases to map where concentrations of insured value exist. For a [[Definition:Property insurance | property]] book, the process might involve overlaying policy-level location data onto hazard maps for windstorm, flood, or earthquake. For [[Definition:Casualty insurance | casualty]] and [[Definition:Specialty insurance | specialty]] lines, aggregation analysis often focuses on shared counterparties, common supply chains, or correlated legal triggers such as mass-tort rulings. [[Definition:Underwriting | Underwriters]] receive real-time accumulation dashboards that flag when adding a new risk would push a geographic zone or peril class past a predefined limit, enabling them to decline, modify, or [[Definition:Facultative reinsurance | cede]] the excess before [[Definition:Binding authority agreement | binding]].<br /> <br /> 🔑 Effective aggregation management has moved from a back-office reporting exercise to a board-level priority, particularly after a series of costly [[Definition:Natural catastrophe | natural-catastrophe]] years and the emergence of systemic perils like [[Definition:Pandemic risk | pandemic]] and cyber accumulation. [[Definition:Insurance regulator | Regulators]] and [[Definition:Credit rating agency | rating agencies]] increasingly scrutinize an insurer&#039;s aggregation framework as part of [[Definition:Own Risk and Solvency Assessment (ORSA) | ORSA]] reviews and capital-adequacy evaluations. [[Definition:Insurtech | Insurtech]] firms have responded by building cloud-native platforms that ingest exposure data in near-real time, apply probabilistic scenarios, and push limits directly into [[Definition:Policy administration system | policy administration systems]] — turning what was once a quarterly report into a continuous underwriting guardrail.<br /> <br /> &#039;&#039;&#039;Related concepts:&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Catastrophe modeling]]<br /> * [[Definition:Risk appetite]]<br /> * [[Definition:Probable maximum loss (PML)]]<br /> * [[Definition:Accumulation risk]]<br /> * [[Definition:Exposure management]]<br /> * [[Definition:Reinsurance]]<br /> {{Div col end}}</div>
