Run-off specialists are increasingly acting as strategic capital partners for insurers, as carriers look to optimize capital, streamline operations and concentrate on core lines, according to a new report from AM Best.
The rating agency said the non-life run-off market continues to see steady transaction activity but has become more concentrated among a small number of large acquirers. Run-off deals were historically initiated mainly by major insurers and reinsurers disposing of discontinued or non-core books of business, but a dedicated class of specialist firms has since developed.
Over time, these platforms have established a defined role in the insurance value chain focused on acquiring and managing legacy liabilities. AM Best noted that this allows cedents to release capital and reduce the administrative burden associated with older portfolios.
“Today, these specialists are increasingly recognized for their technical sophistication, transactional agility, and ability to provide customized capital solutions,” said Dan Hofmeister, associate director at AM Best. He said their capabilities now extend beyond simple run-off of old books to supporting broader balance sheet and risk-transfer strategies.
The report challenges the view that run-off buyers primarily target problematic or high-risk portfolios. While many acquired liabilities can be complex for the original carriers, AM Best said specialists often enter deals with structural protections, including the ability to reprice risk, build in buffers for adverse reserve development and, in many cases, set explicit caps on liability exposure.
According to the report, those features are supported by increasingly detailed data analytics, accumulated claims experience and refined reserving methodologies. These tools can help firms quantify uncertainty in long-tail classes and design structures aligned with their risk appetite and return targets.
Global non-life insurance run-off reserves have climbed to a record $1.129 trillion, according to PwC’s latest Global Insurance Run-Off Survey. Respondents described the legacy market as “stable,” “evolving,” and “dynamic,” with 87% expecting new capital inflows over the next three years and nearly half anticipating a return of larger transactions within 18 months.
AM Best also highlighted execution risks for cedents, especially in transactions involving legal entity transfers or complex, multi-jurisdictional regulatory approvals that can slow or halt deals. “Cedents may also face reputational risk if policyholders or claimants perceive the transfer as a retreat from obligations, especially in high-profile or long-tail liability classes,” Hofmeister said.
The report added that counterparty risk is an ongoing consideration if a run-off specialist later becomes financially strained or manages claims in a way that triggers disputes or residual liability for the original insurer.
As dedicated run-off platforms have expanded, AM Best said cedent priorities have shifted from pursuing legal finality alone to emphasizing capital relief, giving acquirers more latitude to design transactions tailored to regulatory and capital objectives.
