Hiscox said its gross written premiums had fallen three percent from a year ago to 1.17 billion pounds ($1.9 billion), which partly reflected its decision not to take on certain high-risk contracts.
In August, Hiscox had posted a bigger-than-expected interim pre-tax loss of 85.6 million pounds as catastrophe claims nearly doubled due to the Japanese earthquake earlier this year and other disasters.
"Hiscox is in good shape. Our strategy of balance and diversity gives us options in challenging times and the strength of our UK business is proof of this," Chief Executive Bronek Masojada said in a statement.
"Although the wider market is slow to turn, the cumulative effect of international catastrophes is pushing reinsurance rates upwards. As nearly a third of our income comes from reinsurance, we are ready to benefit at the January renewal season," he added.
