View source for Definition:Legacy business

📦 '''Legacy business''' refers to blocks of [[Definition:Insurance policy | insurance]] or [[Definition:Reinsurance | reinsurance]] business that are no longer actively written but remain on an insurer's or reinsurer's balance sheet because outstanding [[Definition:Claims | claims]] obligations, [[Definition:Loss reserves | reserves]], or policy liabilities have not yet been fully settled. Often called "run-off" business, these portfolios can linger for years — sometimes decades in [[Definition:Long-tail liability | long-tail lines]] like [[Definition:Asbestos liability | asbestos]], [[Definition:Environmental liability insurance | environmental]], or [[Definition:Workers' compensation insurance | workers' compensation]] — consuming capital, management attention, and operational resources long after the last [[Definition:Premium | premium]] was collected.

🔄 Managing legacy business is a specialized discipline. Insurers may handle run-off internally through dedicated teams that focus on [[Definition:Claims handling | claims resolution]], [[Definition:Commutation | commutations]], and [[Definition:Loss reserve | reserve]] optimization, or they may pursue external solutions. The legacy market has grown into a sophisticated ecosystem: [[Definition:Run-off company | run-off specialists]], [[Definition:Loss portfolio transfer (LPT) | loss portfolio transfers]], [[Definition:Adverse development cover (ADC) | adverse development covers]], and outright [[Definition:Portfolio transfer | legal entity transfers]] allow carriers to shed legacy liabilities and redeploy capital toward active [[Definition:Underwriting | underwriting]]. Buyers of legacy blocks — often backed by [[Definition:Private equity | private equity]] — acquire these portfolios at a discount and profit by managing [[Definition:Claims | claims]] more efficiently or investing the associated [[Definition:Float | float]] more effectively than the original carrier.

📉 For the broader insurance industry, legacy business is far more than an accounting footnote. Trapped capital tied to old reserves limits an insurer's ability to write new business, pursue growth, or satisfy [[Definition:Solvency | solvency]] requirements efficiently. [[Definition:Insurance regulator | Regulators]] scrutinize legacy portfolios closely because under-reserved run-off books can threaten [[Definition:Policyholder | policyholder]] protection. Meanwhile, the burgeoning legacy transaction market — estimated at tens of billions of dollars annually — has become a vital mechanism for recycling capital within the industry, enabling sellers to clean up their balance sheets and buyers to build scale in [[Definition:Claims management | claims management]] and reserve arbitrage.
