Corporate legal structure is defined as the legal framework of entities that make up the conglomerate.

Business activities structure is defined as the way in which the conglomerate organises and operates the primary business activities in which it is engaged.

Management structure is defined as the form of direct supervision and oversight exercised by management on the corporate and business activities structures, and on the corporate control functions of the conglomerate.

Corporate control functions are defined to be risk measurement, monitoring and control systems and include internal and external audit, financial control, compliance, human resources, and information technology.

The Primary supervisor is generally considered to be the supervisor of the parent or the dominant regulated entity in the conglomerate, for example, in terms of balance sheet assets, revenues or solvency requirements. Where the identity of the primary supervisor is not clear, the relevant supervisors should work cooperatively to identify, on a case by case basis, an appropriate information sharing structure.
