"The continued investment in our international operations and emerging markets is important to the growth of our firm," Aon Chief Executive Greg Case said in a statement on Friday.

Aon's move could boost London's status as one of the pre-eminent global hubs for property and casualty insurance and reinsurance, alongside Zurich, Bermuda and Singapore.
"This is very good news for the London insurance market and for Lloyd's," said John Nelson, chairman of the Lloyd's of London insurance market.
"It will help reinforce London's position in the global insurance marketplace."
Lloyd's, founded 327 years ago, is at the centre of a cluster of insurers and reinsurers in London, backed by specialist bankers and lawyers, which attracts business from across the globe.
Aon's move still requires shareholder approval. Chicago will continue to be Aon's base in the United States, the company said.
Shares of Aon, sponsor of English Premier League football club Manchester United, were down 1.6 percent at $45.9 by 1640 GMT.
