Segment Reporting [Abstract] |
Business segment data | Note 25. Business segment data Our operating businesses include a large and diverse group of insurance, freight rail transportation, utilities and energy, manufacturing, service and retailing businesses. We organize our reportable business segments in a manner that reflects how management views those business activities. Certain businesses are grouped together for segment reporting based upon similar products or product lines and marketing, selling and distribution characteristics, even though those business units are operated under separate local management. We acquired control of Pilot on January 31, 2023. In this presentation, revenues and pre-tax earnings of the Pilot segment in 2023 are for the two months ending March 31. Prior to January 31, 2023, our earnings from Pilot were determined under the equity method and were included in earnings from non-controlled businesses. Revenues and earnings before income taxes by segment for the first quarter of 2024 and 2023 were as follows (in millions).
