The Aon Client Treaty facility has been renewed and will allow for more co-insurance next year, the global broker says.

From January, the facility will support 35% – up from 28.5% – co-insurance on eligible business placed through Aon’s global broking centre and on facultative reinsurance placed by Aon’s reinsurance solutions operation.

The facility is led by QBE and backed by Lloyd’s syndicates.

“As the risks our clients face grow more complex and interconnected, efficient access to risk capital has never been more important,” Aon risk capital CEO Joe Peiser said.

“Increasing ACT to 35% gives clients greater efficiency and confidence when placing their risks.”

Aon says the facility has placed more than $US5 billion ($7.22 billion) in gross written premium since its launch in 2016.

“The expansion for 2027 is particularly significant for facultative reinsurance, which ACT has supported since late 2025,” the company said.

“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.”
