This workforce forms the basis of the HR indicators for ESR. This scope excludes Financial investments and Fintechs. The list of entities in this scope is presentedbelow.

Indicators are broken down by geographic area. The Natixis Worldwide scope covers all of Natixis and its subsidiaries (1) around the world, including Financial investments and entities within the accounting consolidation scope (NatixiAs lgérie).
