Zurich has estimated pre-tax losses from US hurricanes Helene and Milton will be less than $US360 million ($546 million).

The company says its third-quarter results include an impact of $US160 million ($243 million) for Helene, while Milton losses are likely to be less than $US200 million ($304 million).

Natural catastrophe losses for the first nine months of the year have had a combined operating ratio impact of 3.4%, compared with 3.1% a year earlier, the company said in an update last week.

Zurich says revenue in each of its divisions has increased in a “robust” performance.

“Our nine-month results confirm the continued strong momentum across all of Zurich’s businesses,” CFO Claudia Cordioli said. “In property and casualty, margins in commercial insurance continue to be favourable, and performance in retail is improving.”

Property and casualty gross written premium grew 4% to $US36.128 billion ($54.8 billion), driven by rate increases.

Asia-Pacific P&C GWP rose 9% on a like-for-like basis to $US2.864 billion ($4.35 billion), with rebounding travel insurance sales in Australia and higher retail sales the main contributors.

Zurich says life revenue and new business grew strongly, while Farmers Management Services reported 6% growth in underlying fee income.

The company will outline its plans for the next three years at an investor day on November 21.
