Aon has expanded its IBEX transaction insurance program to provide 100 days of interim breach coverage. This update now covers the United Kingdom and European Economic Area, offering risk protection for businesses during the window between signing and closing deals.
Why it matters
The expansion addresses the critical risk gap that often emerges between a transaction being signed and its official closing. By securing coverage during this interim period, firms can finalize M&A activities without leaving themselves exposed to unexpected breaches.
Aon is applying four years of IBEX trading history to this expansion, which leverages the Sidecar X platform that offers up to US $200 million in capacity. The product is supported by A+ AM Best-rated security to back the new interim breach coverage.
The players
Aon
A global professional services firm providing risk, retirement, and health solutions to enterprise clients.
The details
The program utilizes Aon's property data and actuarial analytics to provide interim protection between the signing and closing of a deal. Capacity for the associated risks is managed through pre-negotiated arrangements with insurers via the Sidecar X platform. This structure allows operators to bridge potential liability gaps without requiring separate, bespoke insurance policies for every phase of a transaction.

Market Landscape
This move follows the August 2026 launch of the Aon Sidecar X platform, which modernized how capacity is delivered for representations and warranties. By integrating IBEX into this infrastructure, Aon is positioning itself to streamline insurance procurement for cross-border deals.
Operators managing cross-border transactions in the UK and EEA should evaluate whether this 100-day interim coverage fits their deal timelines to mitigate closing risks. Consult with your insurance broker to determine if your current representations and warranties coverage can be integrated with these new terms.
The takeaway
Securing interim coverage is an essential step in modern transaction management to protect against late-stage breach surprises. Operators should track the availability of this product as a benchmark for negotiating liability terms with insurers in upcoming deals.
