<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>📚 &#039;&#039;&#039;Legacy book&#039;&#039;&#039; refers to a portfolio of [[Definition:Insurance policy | insurance policies]] or [[Definition:Claims reserve | claims reserves]] that an [[Definition:Insurance carrier | insurer]] no longer actively underwrites but remains obligated to manage until all associated liabilities are fully settled. These books typically consist of long-tail lines such as [[Definition:Asbestos liability | asbestos]], [[Definition:Environmental liability insurance | environmental liability]], or older [[Definition:Workers&#039; compensation insurance | workers&#039; compensation]] business where claims can take decades to resolve. A legacy book is sometimes called a &quot;run-off&quot; portfolio, and it sits on the carrier&#039;s balance sheet as a drag on capital until the last claim closes.<br /> <br /> ⚙️ Managing a legacy book requires dedicated expertise in [[Definition:Claims management | claims handling]], [[Definition:Reserving | reserving]], and regulatory compliance across multiple jurisdictions, since many of these portfolios span years or even decades of policy vintages. Carriers often establish a separate [[Definition:Run-off | run-off]] division or outsource administration to a specialist [[Definition:Third-party administrator (TPA) | third-party administrator]] with experience in legacy liabilities. In many cases, insurers choose to transfer legacy books entirely through [[Definition:Loss portfolio transfer (LPT) | loss portfolio transfers]], [[Definition:Adverse development cover (ADC) | adverse development covers]], or outright sales to [[Definition:Legacy market | legacy market]] acquirers who specialize in extracting value from distressed or discontinued portfolios.<br /> <br /> 💡 The strategic importance of addressing a legacy book cannot be overstated for a carrier&#039;s financial health. Trapped capital tied up in old reserves limits an insurer&#039;s ability to deploy resources toward profitable new business or invest in [[Definition:Insurtech | insurtech]] innovation. Regulators also scrutinize legacy reserves closely, and any adverse development can trigger increased [[Definition:Capital requirement | capital requirements]]. By cleanly resolving or transferring a legacy book, a carrier frees up surplus, simplifies its operations, and often improves its [[Definition:Credit rating | credit rating]] — making legacy management a critical lever in modern insurance strategy.<br /> <br /> &#039;&#039;&#039;Related concepts:&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Run-off]]<br /> * [[Definition:Loss portfolio transfer (LPT)]]<br /> * [[Definition:Adverse development cover (ADC)]]<br /> * [[Definition:Legacy insurance carrier]]<br /> * [[Definition:Legacy market]]<br /> * [[Definition:Claims reserve]]<br /> {{Div col end}}</div>
