Bermuda re/insurer Alterra Capital Holdings Ltd expects losses of up to $100 million from last month’s Japanese earthquake and tsunami.The company said in a statement today that its preliminary loss estimate of between $60 million and $100 million, based on industry loss range of $20 billion to $35 billion, equates to 2.1 percent to 3.4 percent of Alterra’s total shareholders’ equity at the start of the year.Alterra said that it could take a further investment loss of up to $25 million through a catastrophe bond which it owns and which has exposure to the Japanese disaster.The company estimates that its losses from other first-quarter catastrophe events continue to be within previously announced ranges.Alterra CEO Marty Becker said: “We continue to be saddened by the extent of damage and suffering that the Japanese earthquake and tsunami have caused. At a magnitude of 9.0, the earthquake was one of the largest ever recorded. Loss estimates are still immature, and we are concerned that the final industry loss may be larger than many of the existing estimates. Accordingly, our estimate of losses to Alterra reflects a wide range of potential industry outcomes.”
