Integration and restructuring costs left Willis Towers Watson with a third-quarter net loss of $US32 million ($41.67 million).

This compares with a pro-forma net profit attributable to Willis and Towers Watson of  $US209 million ($272.08 million) in the corresponding period last year.

Broker Willis merged with professional services company Towers Watson in January.

The third-quarter loss includes $US49 million ($63.8 million) of restructuring costs and $US36 million ($46.87 million) of integration expenses.

Total revenue was $US1.78 billion ($2.31 billion), up 2% on the Willis and Towers Watson pro forma revenues.

Commissions and fees for investment, risk and reinsurance services fell 9% to $US292 million ($380.34 million).

CEO John Haley says he is happy with continued revenue growth, driven by the acquisition of French broker Gras Savoye and organically through the Exchange Solutions platform.

“I am pleased with the progress against our integration plans, revenue synergy activities and our enhanced efforts to manage profit margin,” he said.

“We expect to see strong earnings growth [this year] and I remain very confident in achieving our long-term merger objectives.”
