Segment Reporting [Abstract]

Schedule of revenues and earnings or loss before income taxes by segment

Our operating businesses include a large and diverse group of insurance, 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. Revenues and earnings before income taxes by segment for the third quarter and first nine months of 2022 and 2021 were as follows (in millions).
