Subject:

Moving Corporate Headquarters to London

Date:

January 13, 2012

 

Today, we announced that we will move our corporate headquarters from Chicago to London and Aon’s incorporation from Delaware to the United Kingdom. We believe this move allows us to strengthen Aon’s global business operations and further align resources to drive our long-term growth strategy.

 

Our industry, like the rest of the global economy, is constantly changing. We must align ourselves to more effectively serve our clients in every part of the world, which will help us stay ahead of the competition and increase revenue growth and market share. This decision reinforces our strategy to deliver the highest value to our clients, attract and retain the best talent, and achieve operational excellence. It will also create increased financial flexibility and cash flow, which will allow us to make even greater investments in our business, operations and people.

 

I want to emphasize that we expect there to be minimal impact on our global colleagues. This decision will not cause any loss of jobs. A small number of certain key senior executive positions will be relocating to London. We will continue to grow and invest in Chicago and the U.S. by adding more than 1,000 jobs in the U.S. market during 2012, and moving 750 positions to Chicago.

 

Strengthening Aon’s presence in London will bring us even closer to our global clients, especially those looking for the most innovative solutions or those from fast-growing developing countries who see the value of conducting transactions in London. For more than 400 years, London has been a historical and global center of insurance and risk management innovation, so this decision provides us with the opportunity to create a higher degree of innovative products and solutions to help clients mitigate their most complex and challenging global issues regarding risk and people.

 

Chicago has been our home for many years and will continue to play an important role for our firm as Aon’s headquarters for the Americas, including the U.S., Latin America and Canada. Similarly, Lincolnshire will remain the headquarters for our Aon Hewitt business.

 

We anticipate this move occurring in the second quarter following approval by our stockholders. In the interim, we recognize that you may have additional questions. Please be assured that leaders from across the firm will be available to answer your questions as they arise and will get back to you quickly with a response. In the meantime, please send your questions to aon.united@aon.com.

 

Thank you for all you do to support our clients and fellow colleagues. I look forward to continuing to work with you to build our firm.

 

Best,

 

Greg
