The acquisition of Conrad & Sons will add complementary skills and resources to Aon Consulting's existing business in Singapore and in the broader Asia Pacific region, particularly in the area of flexible benefit design and delivery.

"Conrad & Sons' team of professionals are a welcome addition to our existing team at Aon Consulting in Singapore," said Edouard Merette, Singapore-based CEO of Aon Consulting Asia Pacific. "At a time when organizations aspire to provide innovative and flexible benefits design and ensure an effective and cost efficient delivery of benefit coverages, our professionals are now in an even better position to guide and assist clients in this journey.

"This acquisition follows a number of recent senior leadership additions across Asia Pacific, as Aon Consulting increasingly becomes the destination of choice for top talent in the industry and the provider of choice to leading organizations in the region as they shape their workforce through innovative benefits, compensation and talent management strategies and solutions," Merette said.

Collin Chiew, CEO of Conrad & Sons, added, "By being part of Aon Consulting and the broader Aon organization, we will now be able to respond to the regional needs of -- and increase the scope of services we can offer to -- our clients. This is exciting for my team and is good value for our clients."

Chiew will become managing director of the combined operation of Aon Consulting in Singapore. The current managing director, Richard Tan, will become chairman.
