Aon Risk Solutions Australia says James Baum will take over as CEO in the second quarter from Lambros Lambrou, who will move into a broader role with the global business.

Mr Baum is currently Commercial MD and Aon Broking Pacific Chairman, and has been an insurance broker for more than 20 years.

He joined Aon in 2005 and has worked in every facet of the placement business, the company says.

As reported in a Breaking News bulletin last week, Mr Lambrou will move to his new role in the second quarter after heading the Australian business since late 2013.

The company says CFO and Aon Pacific COO Bill Hooper will also represent the Pacific region on the global Aon Risk Solutions operating committee, adding to his current responsibilities.

Mr Hooper will work closely with Mr Baum, the company says.

Before moving to Australia, Mr Hooper was Aon Asia-Pacific CFO based in Hong Kong, where he oversaw businesses in 20 countries, including five joint ventures.
