As Carriers Release Loss Estimates, Total Continues to Climb

RMS' estimate for total Japan insured losses has reached $34 billion, but some carriers are still basing their loss estimates on earlier numbers.

Three more carriers announced losses related to the Japan earthquake and tsunami this week. Alterra Capital Holdings expects $60 million to $100 million; Everest Re, $320 million; and Aspen Insurance Holdings, $160 million.

However, those losses are based on industry loss estimates of around $30 billion. Yesterday, RMS revised up once again its estimate for total industry losses .

It's understandable that the fluid nature of such an event makes it difficult for insurers to come up with firm numbers. Since most carrier estimates are based on percentages of their view of the total losses, it's unlikely that they will fluctuate too much — by their very nature, some "give" is built in. Still, this serves as a reminder of the uncertainty that accompanies major cat events.
