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). The number of shareholders of a credit union is limited and formalized by a list. Limit of the number is defined by the assembly and such assembly establishes the charter. First Credit Union was savings unprofitable institution, or rather credit cooperative, providing services to its members. Credit union services are available only to its shareholders. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. Taking a decision to join a credit union, citizens create an organization through which they participate in the shared savings by mutual crediting and joint (collective) use of personal savings. In the case of default the shareholder - individual will respond with its property and, in addition, is jointly and severally liable with the credit union's commitments. To increase the number of credit unions in 1979 was adopted the corresponding law that serves as the legal basis of their activity. Credit union as a consumer cooperative operates on the principles of equality of all its members. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the credit union.
