The Statement of Issues outlines the Commission’s potential competition issues with the acquisition following its initial investigation. A Statement of Issues is not a final decision and does not mean that the Commission intends to decline or clear the acquisition. 

The Commission is seeking submissions from Aon and Willis Towers Watson and other interested parties on the issues raised in the Statement of Issues.

The Statement of Issues can be found on the case register.

Submissions can be sent by email to with the reference “Aon/WTW” in the subject line. 

Submissions are due no later than close of business on 26 January 2021, with cross-submissions due no later than close of business 2 February 2021.

The Commission is currently scheduled to make a decision on the application by 26 February 2021. However, this date may be extended.


The Commission will give clearance to a proposed merger if we are satisfied that the merger is unlikely to have the effect of substantially lessening competition in a market.

Further information explaining how the Commission assesses a merger application is available on our website.
