LONDON, 12 October 2006 - Aon, a leading insurance broker and risk management consultant, today announced the opening of its Captive Services Group office in Hong Kong, which will enable it to take advantage of increasing risk exposures coming out of the Asia Pacific region, particularly China, as well as to increase the choice of captive operations for its existing clients.

Stephen Cross, chief executive officer of ACSG, comments: “Captives are not a new concept, but are relatively new to Asia.  Aon sees a large number of emerging companies from this region that would fit the typical captive profile.  In particular, mainland China is witnessing phenomenal levels of direct foreign investment, which in many cases take the form of a joint venture structure.  This will further enhance opportunities for Hong Kong based captives.”

The Hong Kong office will be overseen by Clive James, the newly appointed group managing director of Aon Insurance Managers (AIM) Global.

AIM is witnessing a rapidly growing demand for captives from the Asia Pacific market place, seeing growth in Australia and Japan, where clients have historically used Singapore as a domicile. In addition, alternative risk transfer opportunities will increase as the Chinese economy continues to grow, with Hong Kong well placed to capitalise.

Clive James, group managing director of AIM Global, the captive management division of Aon Captive Services Group (ACSG), said: “As the recognised leader in the captive market, ACSG will always establish locations aligned to future client demand.  Hong Kong is our 29th office in a captive jurisdiction and our second in Asia, alongside Singapore. With over 1,350 clients worldwide we continue to strive to broaden the options for our clients and will look towards further expansion into 2007.”
