Amlin has said that it expects an insured loss of $52m from Hurricane Wilma.
In a trading update, Amlin said that Syndicate 2001's premium income to the end of October 2005 was £715m, in line with market expectations.
The company said that its average renewal rate fell 4%, reflecting market conditions prior to the season's hurricane losses, but added that rate movements would accelerate for the January renewals.
Amlin said that the 2004 year of account forecast has remained stable, despite absorbing a net claim estimate of approximately £19m for the 2005 hurricane losses, with the underlying improvement reflecting better than forecast development across all divisions of the Syndicate.
