Aon has reported a rise in first quarter revenues and earnings and says global volatility has further reinforced the relevance of its business strategy.

Net income increased to $US1.02 billion ($1.44 billion), up 12% on the previous corresponding quarter, while revenues gained 4% to $US3.7 billion ($5.2 billion) including impacts from foreign currency translations.

Revenue from the largest business line, Commercial Risk Solutions, grew 5% to $US1.7 billion ($2.4 billion), with organic growth reported across every major geography. Retentions, new business generation and management of the renewal book portfolio boosted the result, the global broker says.

“Our performance demonstrates how increasing global volatility has further reinforced the relevance of our Aon United strategy,” CEO Greg Case said.

“In the face of rising complexity and uncertainty, our colleagues will continue to employ the advanced analytics and underlying technology of our Aon Business Services platform to identify areas of unmet need, improve service standards, and accelerate delivery of new solutions that provide clients the clarity and confidence they need to protect and grow their business.”

Reinsurance Solutions revenue rose 6% to $US976 million ($1.38 billion), health increased 4% and wealth experienced a 3% decline.

Aon says highlights during the quarter include the announced acquisition of actuarial software platform Tyche. The platform will expand the group’s existing capital modelling capabilities to help clients rethink access to capital and make better business decisions, it says.
