BUSINESS SEGMENT INFORMATION

The following table is a summary of segment information for the three and nine months ended September 30, 2024, and 2023. The “management approach” has been used to present the following segment information. This approach is based upon the way the management of the Company organizes segments within an enterprise for making operating decisions and assessing performance. Financial information is reported on the basis that it is used internally by the chief operating decision maker (CODM) for evaluating segment performance and deciding how to allocate resources to segments. The Company’s chief executive officer has been identified as the CODM.

Segment asset information is not presented because it is not used by the CODM at the segment level. The Corporate costs not allocated to segments include the costs of centralized functions, other charges such as acquisition expenses, spin-off costs, remaining unallocated costs of the CDCS business, and COVID-19 related costs unrelated to the segment. Centralized functions include corporate governance, executive management and related human resources, finance, legal, risk management, and information technology functions.
