Aon stock: ACT capacity expands to 35% for eligible 2027 placements

Aon has renewed its Aon Client Treaty facility for 2027, lifting co-insurance capacity for eligible placements to 35 percent from 28.5 percent. The expanded arrangement will apply from January 1, 2027, giving clients access to a larger committed share of selected insurance and reinsurance risks.

Insurance Asia reported that the facility covers eligible business placed through Aon's Global Broking Centre and facultative reinsurance placed by Aon's Reinsurance Solutions. QBE leads the facility, with backing from Lloyd's syndicates.

Broader capacity for complex risks

Clients using the facility can access capacity on the same terms and pricing as the lead placement, subject to client agreement, eligibility rules, local laws and Aon's conflicts of interest framework. Eligible clients may also receive a 1.5 percent ACT Client Dividend on the expanded share where permitted.

The change is particularly relevant to facultative reinsurance, which supports large or complex individual risks that may not fit standard treaty programmes. Insurance Asia said the facility has placed more than 5 billion US dollars in gross written premiums since its launch in 2016.

Aon stock traded at 300.40 euros on Lang & Schwarz at 17:39 CET on Tuesday, November 10, 2026.
