Bermuda-based XL Capital Ltd. expects to record a loss of about $830 million in the fourth quarter related to a dispute with Credit Suisse Group over reserves at some insurance operations it bought from the Swiss bank, Bloomberg News reported.

An independent actuary ruled in a draft report that XL will get about $575 million from Credit Suisse, an amount closer to what Credit Suisse had estimated than to what XL was seeking. The report will be completed on December 5, Hamilton, Bermuda-based XL said yesterday in a statement.

Credit Suisse in 2001 sold the international unit of its Winterthur Group insurance business for $405 million to XL. It bought Winterthur in 1997 under a strategy of combining banking and insurance. Zurich-based Credit Suisse in February had set aside about $258 million related to the matter.

XL had a third-quarter loss of $1.04 billion, or $7.53 per share, on claims from Hurricanes Katrina and Rita. A message left for XL spokesman Roger Scotton wasn't immediately returned.

The shares of XL rose $1.54, or 2.1 percent, to $73.74 in New York Stock Exchange composite trading. The stock has fallen 5 percent this year.
