### Summary of Continuing and Legacy Business
The following tables present supplementary financial information regarding our two reporting segments, Reinsurance and Insurance, for the twelve months ended December 31, 2023, 2022, 2021, 2020, 2019 and 2018 to show the impact on our financial performance from the business which we have ceased underwriting and has been classified as “Legacy.” We have not presented these tables for the twelve months ended December 31, 2024 as we have ceased writing legacy business and they have not had any impact to our financial information in 2024.

“Legacy” business has been represented on a like for like basis, meaning all the same lines of business have been included as Legacy in all the tables. We believe this presentation provides for a more complete understanding of the impact that these lines of business have had on our underlying performance. The following tables show U.S. dollars in millions, except for percentages.
