Big Four (audit Firms) - Legal Structure

Legal Structure

None of the Big Four accounting firms is a single firm - rather, they are accounting networks. Each is a network of firms, owned and managed independently, which have entered into agreements with other member firms in the network to share a common name, brand and quality standards. Each network has established an entity to co-ordinate the activities of the network. In one case (KPMG), the co-ordinating entity is Swiss, and in three cases (Deloitte Touche Tohmatsu, PricewaterhouseCoopers and Ernst & Young) the co-ordinating entity is a UK limited company. Those entities do not themselves practice accountancy, and do not own or control the member firms. They are similar to law firm networks found in the legal profession.

In many cases each member firm practises in a single country, and is structured to comply with the regulatory environment in that country. In 2007 KPMG announced a merger of four member firms (in the United Kingdom, Germany, Switzerland and Liechtenstein) to form a single firm.

Ernst & Young also includes separate legal entities which manage three of its four areas: Americas, EMEIA (Europe, The Middle East, India and Africa), and Asia-Pacific. (Note: the Japan area does not have a separate area management entity). These firms coordinate services performed by local firms within their respective areas but do not perform services or hold ownership in the local entities.

The figures in this article refer to the combined revenues of each network of firms.
