What is the main purpose of the announced changes?

The main purpose of the announced changes is to further accelerate Aon's 'Aon United' strategy by realigning the company's reporting structure into four distinct solution lines. This is intended to provide a clearer presentation of its principal service line revenues and organic revenue growth.

Will these changes affect Aon's overall financial performance or reported results?

No, these changes primarily affect the internal reporting and presentation of revenue by service line. They have no impact on Aon's previously reported consolidated financial statements, overall results of operations, or total organic revenue growth. Aon continues to operate as a single reportable segment.
