Aspen Insurance Holdings Ltd. put its losses fromThailandat about $54 million. Axis says it expects a loss of $48 million from the flooding to negatively impact results in the fourth quarter.

Alterra Capital Holdings adds an expected $30 million—primarily from contingent business-interruption claims—in Thailand-related, fourth-quarter catastrophe losses.

The massive flooding in Thailand—which began last summer but peaked during the 2011 fourth quarter—could cost the insurance industry between $10 billion and $20 billion. Aspenbases its estimate on a total loss to the industry of $15 billion—the same total used by PartnerRe in coming up with its expected fourth-quarter charge of $120 million.

Other than losses fromThailand, insurers have been adding to previous insured-loss estimates from earthquakes last year in Japanand and New Zealand.

Aspen says it has chosen to up its loss estimate from the Tohoku earthquake by $36 million “as a result of new information in respect to a major Japanese Mutual, to which Aspen is now assuming a total loss from its participation.”

Added losses from the earthquakes are predicted to add $75 million to Axis' fourth-quarter catastrophe losses. The company says a “significant” part of the loss is driven by its decision to “reserve the full limit of its exposure for a large mutual, after consideration of updated loss advices.”

After totaling Thai and additional New Zealand-related losses, New York-based Transatlantic says it expects to record a total of $110 million in catastrophe losses for last year's final quarter.

Alterra says it will record a total of $50 million in fourth-quarter catastrophe losses after factoring in losses from Japanand and New Zealand.
