Representative organization, leading the coordination work in the field of development of both global and national credit union movement is the World Council of Credit Unions (WOCCU) established in 1971 (headquartered in Madison, USA). Like the credit cooperatives, credit unions form associations of a higher level, which are called corporate credit unions. Principles of cooperative democracy and interaction were adequate to the purposes for which people joined credit unions. When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Income received by the credit union shall be distributed among the shareholders or spent for the depreciation of services, that is, are the most effective means of meeting the needs of shareholders. Is necessary that all shareholders of the credit union were members of a single community, would know each other well enough to enjoy mutual trust. Share contributions are transferred to the credit union on the basis of membership for the whole stay of a shareholder as member of the credit union and are the basis of membership. Credit unions of the open type are still controlled by their members, but at the same time provide services to people who are not its members (external customers).
