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. 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. The difference between credit unions and banks is clearly is apparent when comparing the structure of assets and liabilities of credit unions and banks. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. All the members of the credit union, regardless of gender, ethnicity, religious and political beliefs, as well as the size of the monetary share have equal rights. National Credit Union Insurance Fund was created by Congress in 1970 to insure deposits of credit union members in the amount of 100 thousand dollars. Worldwide credit union movement is represented by regional confederations and national organizations within the World Council of Credit Unions.
