(Reuters) - Lloyd's of London underwriter Hiscox Ltd HSX.L on Monday reported a 14.3 percent rise in gross written premiums for the first nine months of the year, but warned that growth could moderate over the balance of the year.

The insurer, which underwrites a range of risks from oil refineries to hijacks, said it had been hit by catastrophes in the United States and the Far East and reserved net $125 million to cover claims and reduced profit commissions because of Hurricanes Florence and Michael and Typhoons Jebi and Trammi.
