Aon Holdings Asia, created a year ago by United States insurance giant Aon Group, claims to have overtaken Jardines to become the largest risk-management operator in Singapore following a string of acquisitions. Yesterday it announced it had merged a string of smaller brokers it had bought in the past year with its operations to form newly named vehicle Aon Singapore. Regional chief executive Bernie Fung said the merger would automatically make it the market leader in terms of revenue, experience and resources. Aon Singapore will be spilt into three divisions offering services in retail broking, reinsurance broking and employee benefits: Aon Risk Services Singapore, Aon Reinsurance Brokers Asia and Aon Benefits Insurance Brokers. The group will specialise in assisting private corporations and government bodies, as well as other insurance companies, in managing their risk. Aon Risk is the result of a merging of Rollins Hudig Hall, Heath Hudig Langeveldt, Inchcape Insurance Brokers, Alexander & Alexander and Minet Insurance Brokers. Aon Reinsurance has been further strengthened by the injection of Alexander Howden. While Aon Benefits is a new vehicle for Singapore which will draw on the specialist skill of other Aon-merged companies in the republic as well as its international parent to offer services in employee benefits and consulting, Mr Fung said existing Aon clients and clients of the merged companies would have access to Aon Group's worldwide network. The organisation employs more than 40,000 people in 60 countries. Aon Singapore chief executive Chris Lawrence said: 'Clients will benefit from Aon's leading position in Singapore and globally. Our significant industry leverage will allow us to offer a very competitive range of products.' Aon Singapore will look after the group's interests in the region, excluding Hong Kong, China, Macau and Japan. The greater China region, excluding Taiwan, will be managed from Hong Kong, where the group announced a similar restructuring last week. Aon Holdings Asia has operations in 14 countries in Asia, including offices in Beijing and Shanghai, employing 1,100 people in the region.
