| Definition | An operational unit defined by the company itself; how the group organizes and reports its operations (AXA France, AXA XL). |
🗂️ Business unit is the label a company gives to an operational division it defines for itself: a perimeter of businesses run by one management team, with its own targets and its own line in the group's reporting. The axis of division is the company's choice. AXA cuts by geography and by specialty franchise, so AXA France and AXA XL are business units; another group might cut by customer type or by brand. Nothing in accounting standards fixes the term; the org chart does.
🧭 Business units matter to reporting because segment disclosure follows management structure: IFRS 8 requires listed companies to report the operating segments management actually steers by, so published segment tables usually mirror the business-unit map. The unit axis is organizational, which distinguishes it from the risk-based axis of the business segment. One business unit can write several segments, as AXA France does with both life & health and property & casualty, while a segment total cuts across many units.
🔎 For a reader of company documents, the business-unit map is the decoder ring for every figure below group level: a number is comparable to last year's only if the unit's perimeter has not moved. Perimeters do move, when groups reorganize, acquire, or dispose, and restated comparatives follow. Checking which units exist in a given reporting year, and what each contained, is the first step in tracking any division-level trend through time.
