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). Activity of the credit union consists of organizing mutual financial assistance by meeting the needs of its members in the services of saving and obtaining loans. Credit union is created by a group of members who pursue a common interest. Agreeing to make regular contributions, they create a fund from which can borrow money for investments and replenishment of working capital at favorable interest rates. Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. Membership in the credit union forms responsible citizens and conscientious attitude to their obligations as a norm of behavior, identify the value of a decent man's reputation in the business turnover. Initially, the target groups of credit unions were farmers (Raiffeisen), and now they include both individuals (credit unions), and organizations. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. Credit union as a consumer cooperative operates on the principles of equality of all its members.
