American Safety Insurance Holdings Ltd. has announced it expects to report pre-tax losses of between $5 million and $7 million from the New Zealand earthquake and other events in the first quarter.The insurer said that catastrophe losses within the assumed reinsurance division attributable to the New Zealand earthquake were expected to be from $1.5 million to $2 million and other weather related property losses within its excess and surplus lines division were expected to be between $1 million to $1.5 million.The remainder is primarily attributable to prior year casualty net reserve strengthening in the assumed reinsurance division related to two contracts that have been non-renewed.Additionally, the company is in the process of assessing its exposure to the earthquake and tsunami that struck Japan on March 11, 2011.
