Due to the significant impact that this required investment company classification has on the presentation of the company’s operating cash flow, the company has elected to remove the impact of these net investing activities of these investment companies. The investment company presentation is not consistent with our consolidated cash flow presentation. These net investing activities are more appropriately classified outside of operating cash flows, consistent with our consolidated investing activities, and may impact a reader’s analysis of our underlying operating cash flow related to the core insurance company operations. Accordingly, we believe that it is appropriate to adjust operating cash flow for the impact of these consolidated investment products."]

For the ROTE calculation, the denominator is also adjusted to exclude Chubb goodwill and other intangible assets, net of tax. These measures enhance the understanding of the return on shareholders’ equity by highlighting the underlying profitability relative to shareholders’ equity and tangible equity excluding the effect of these items as these are heavily influenced by changes in market conditions.

[null,null,"Catastrophe losses (Cats): We generally define catastrophe loss events consistent with the definition of the Property Claims Service (PCS) for events in the U.S. and Canada. PCS defines a catastrophe as an event that causes damage of $25 million or more in insured losses and affects a significant number of insureds. For events outside of the U.S. and Canada, we generally use a similar definition. Catastrophe loss events are events that occurred in the current calendar year only. Changes in catastrophe loss estimates in the current calendar year that relate to loss events that occurred in previous calendar years are considered prior period development."]
