In the U.S., credit unions have a clear organizational structure. All credit unions belong to one or the other parent credit union (there are 35 of them in the U.S.). 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). Over 30% of the assets of credit unions are investments in government securities, certificates of deposit of banks and savings loan associations, as well as in the parent credit unions, and other risk-free investments. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. The right to use the services of the credit union have only its members. Worldwide credit union movement is represented by regional confederations and national organizations within the World Council of Credit Unions. Today, the World Council of Credit Unions is represented as members four regional confederations and twelve national associations.
