Reading notes
Share is each line’s part of that breakdown. Margin is the company’s reported segment operating income divided by that segment’s revenue. Companies define segment profit differently and may re-cut segments over time, so a company’s lines can differ between years. Breakdowns that do not add up to within 5% of reported revenue are left out.
