International Assurance of Tennessee and Aran Insurance Underwriters, two managing general underwriters specialising in medical stop-loss coverage owned by Jencap Group, have combined operations under a new unified brand, Jencap A&H Insurance Solutions. The combination reflects a broader consolidation trend among specialist stop-loss MGUs at a moment when the market they serve is expanding rapidly and its regulatory boundaries remain actively contested.
IAT, founded in 1984 and based in Franklin, Tennessee, has written employer and medical stop-loss insurance for more than 40 years, including coverage for prisons and jails - an unusual niche that distinguishes it from standard employer stop-loss underwriters. Jencap acquired the company in January 2022. AIU, founded in 2010, is a full-service MGU offering medical stop-loss insurance to self-funded employer group plans and was an early adopter of reference-based pricing in the stop-loss industry. Both will now operate under the Jencap A&H name.
Scott Eastland, president of Jencap A&H, said the combination was "a meaningful step forward for our business and our partners."
The combined platform is backed by the wider Jencap Group, which administers roughly 30 programmes across admitted and non-admitted lines, partnering with a national network of independent agents, wholesalers, third-party administrators and affinity groups. Its programme brands include MiniCo, Eventsured and HRMP alongside other specialty divisions spanning property and casualty as well as accident and health lines, giving Jencap A&H access to shared back-office infrastructure, carrier relationships and distribution reach as it integrates the two legacy MGUs.
The rebrand comes as the US medical stop-loss market continues to expand rapidly alongside rising claims costs. The global stop-loss insurance market was valued at $26.9 billion in 2024 and is projected to grow to $113.5 billion by 2034, driven largely by increased adoption of self-funded health plans among small and mid-sized employers, according to Allied Market Research.
That growth reflects a structural shift in how American employers fund health benefits. Roughly 65% of workers with employer-sponsored health coverage are enrolled in self-funded plans, up from 44% in 1999, according to a US House Ways and Means Committee report - the date of which should be confirmed against the primary source before publication, as "recent data" is too imprecise for a figure of this specificity. That shift has been driven in large part by the availability of stop-loss coverage that lets employers cap their exposure to catastrophic claims, making the MGU the enabling mechanism for a market transformation now four decades in the making.
Stop-loss MGUs are operating against an evolving regulatory landscape. Because stop-loss coverage sits at the boundary between self-funded ERISA plans and state-regulated insurance, several states have moved to regulate policies with low attachment points on the grounds that they function as de facto health insurance for very small groups. Congress has considered legislation - the Self-Insurance Protection Act - that would clarify that stop-loss insurance is not health insurance coverage under ERISA and would limit states' ability to restrict its availability, though the bill has not become law.
Consolidation among specialist MGUs has become more common as underwriters look to combine underwriting expertise and distribution scale to compete for business from brokers and third-party administrators navigating both rising claims costs and regulatory uncertainty. Jencap A&H's combination of two MGUs with a shared parent, each carrying decades of stop-loss experience, reflects that trend toward scale in a market where underwriting discipline and data capability are becoming key differentiators.
