Preliminary estimated losses related to the mid-August 2015 Tianjin, China port explosion are approximately $100 million, of which approximately 30% of this is attributable to the Insurance segment and 70% to the Reinsurance segment;

Preliminary estimated losses related to natural peril catastrophes for the third quarter 2015 of approximately $30 million, primarily attributable to the Reinsurance segment. Natural peril catastrophes include the Chilean earthquake and development on prior quarter events the majority of which pertain to the 2015 US Winter Storms.

Given there is currently a wide range of estimates for the extent of total economic and insured industry losses for these events, the Company’s loss estimates involve the exercise of considerable judgment and are accordingly subject to revision as additional information becomes available. Actual losses may differ materially from these preliminary estimates.
