Aon has reported an increase in second-quarter profits, despite falling reinsurance revenue.

Net income attributable to shareholders was $US304 million ($323 million), compared with $US241 million ($256 million) in the corresponding period last year.

In the risk and insurance brokerage business, total revenue was flat at $1.9 billion ($2.02 billion).

Revenue in the Americas increased 2%, while international revenue gained 3% thanks in part to growth in Asia and New Zealand.

Reinsurance revenue fell 4%.

For the half year, net income attributable to shareholders grew 25% to $US629 million ($669 million).

President and CEO Greg Case says the results reflect “underlying operational improvement and effective capital management, despite challenges from both foreign currency translation and market impact”.
