Aon, a leading global professional services firm, has announced the successful renewal of the Aon Client Treaty (ACT). From 1 January 2027, the facility will enable 35% co-insurance on eligible business placed through Aon's Global Broking Centre and on facultative reinsurance placed by Aon's Reinsurance Solutions, up from 28.5%.

According to the company’s press release, strong support from market partners has matched growing client demand for committed capacity. Where permitted by local law and regulation, and subject to eligibility, the ACT Client Dividend of 1.5% will apply to the larger 35% share.

"As the risks our clients face grow more complex and interconnected, efficient access to risk capital has never been more important", said Joe Peiser, CEO, Risk Capital, Aon. "Increasing ACT to 35% gives clients greater efficiency and confidence when placing their risks. ACT is a clear demonstration of how Aon's integrated Risk Capital approach delivers improved outcomes for clients", Joe Peiser added.

The expansion for 2027 is particularly significant for facultative reinsurance, which ACT has supported since late 2025. Insurers placing large or complex individual risks through Aon can now access committed capacity, subject to eligibility criteria, for a larger portion of each placement.

“Facultative reinsurance has quickly become one of the facility's most important areas of growth and moving to 35% allows us to build on that momentum for clients", commented Helene Madell, CEO, Global Broking Centre, Aon.
