stumbled when the insurance company said its Folksamerica Reinsurance unit increased its gross loss estimates for hurricanes Katrina, Rita and Wilma by $203 million, net of reinstatement premiums.

Without other action, the move would exhaust the bulk of Olympus' capital. However, White Mountains is in advanced talks with Olympus and its two largest shareholders regarding an arrangement to reimburse the firm for up to $137 million of the ceded losses.
