The acquisition of Cosegur Re, the largest reinsurance intermediary in Peru, offers Aon Re Global and its clients in Central and South America additional expertise, particularly in the areas of life and marine reinsurance.

Terms of the agreement, which closed May 2, were not disclosed.

"The acquisition of Cosegur Re and its team is terrific for Aon Re Global and, most importantly, for our clients," said Michael D. O'Halleran, executive chairman of Aon Re Global. "Combining Aon Re Peru with Cosegur Re brings new marketplace expertise for Aon Re's current client base and new market access and servicing capabilities for Cosegur Re's clients."

"While Aon Re Global is already the world's largest reinsurance intermediary, our commitment is to continue to be the industry leader everywhere in the world," said Andrew Appel, chief executive officer of Aon Re Global. "Bringing the Cosegur Re team into the Aon Re Global network will provide significant value to our clients in the region while strengthening our global talent base and integrated capital solutions approach."

Cosegur Re founders Jose Antonio Cadarso and Juan Diego Cadarso join Aon Re Peru as chief executive officer and chief operating officer, respectively.

"We are thrilled to be joining Aon Re Global and to have access to the vast network and first class resources that only Aon Re Global can offer," said Jose Antonio Cadarso. "This merger will provide us the necessary tools to develop new business opportunities and provide more value for our clients."

Juan Diego Cadarso added: "Being an independent reinsurance broker, we were looking for ways to have direct access to all worldwide reinsurance markets for the benefit of our clients. Aon's 'One Global Team' approach was a key factor in our decision to join them."

Aon Re Peru currently employs 11 people. As the largest reinsurance broker in the region, Aon Re Latin America has offices in 10 countries and 230 employees.

"Through our dedicated broking resources in London and Miami, and access to the London, European and Bermudan markets, Aon Re Latin America is committed to being a strategic partner to our clients in the region," said Mike Hughes, chief executive officer of Aon Re Latin America. "My personal thanks to Bill Farmer, vice chairman of Aon Re Americas, and Mike Bungert, chairman and chief executive officer of Aon Re Americas, and the many others who have worked to strengthen our team in the region, particularly through this acquisition."
