 * A company's revenue disaggregated by business segment, geography, and product/service from its dimensional XBRL facts, annual fiscal years only, latest restated values. Also carries per-segment operating income and margin when tagged. Empty axes mean the issuer reports revenue only as a consolidated total. Axis members may overlap hierarchically (a parent line tagged alongside its children), so never sum members — consolidatedRevenue carries the real per-year totals.
