An investment holding company that actively manages and controls subsidiary companies, provides banking services and loans to them, and exercises significant influence over their operations carries on a 'financial enterprise' within the meaning of Government Notice R340 issued under the Regional Services Council Act 109 of 1985, specifically falling within the definition of 'any company which carries on business as an investor of money'. Such a company is not a mere passive investor comparable to an ordinary citizen holding shares, but is engaged in continuing commercial activity. Dividend income received by such a holding company from its subsidiaries and associated companies constitutes 'consideration' in respect of 'leviable transactions' and is therefore subject to regional establishment levies. The activities of an investment holding company cannot be artificially compartmentalized; where a company's stated main object is to carry on business as an investment holding company, its investment activities constitute an enterprise and activity of a continuing nature, particularly where it exercises control, provides financial support, and is intimately involved in the affairs of the companies in which it invests.
