Knowing who owns and controls a company helps you understand how it functions and connects globally. Our corporate hierarchy data allows you to trace relationships between parent companies, subsidiaries, and shareholders, showing control, structure, and risks within any global group. This insight is vital when looking at Aon or other multinational corporations for compliance purposes, market analysis, and better data management. With verified ownership records of over 380 million companies worldwide, CompanyData.com delivers clear data on corporate ownership across industries and countries.
At CompanyData.com, each company profile including Aon is organized using a three-level model: Global, National, and Local headquarters. This structure shows how every entity fits within the larger corporate family.
Each entity receives a unique identifier to link subsidiaries with parent firms, trace ownership paths, and enable easy integration with your internal systems.
Control is defined based on ownership shares. When a company owns over fifty percent of another, it is viewed as a controlled subsidiary. Our focus on majority-controlled subsidiaries provides a clear picture of ownership and corporate hierarchy, capturing the full global scale of groups like Aon.
This methodology highlights who ultimately makes decisions within the Aon Group, streamlines compliance checks, aids in merger and acquisition analysis, and supports risk management. By mapping each company with verified ownership data, CompanyData.com gives you confidence to explore Aon’s corporate structure fully. With over 1,500 entities linked across more than 85 countries, our platform creates transparency for complex international corporate families.
