In 1908. the spread of credit unions has reached the United States. In 1935 President Roosevelt signed the state Charter on credit unions, which became a law. 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. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. The right to use the services of the credit union have only its members. The specifics of credit unions and, in some sense, their uniqueness lies in the fact that they work not for profit and do not appropriate profit. Unlike banks credit unions limit their activities to a closed circle of people. Worldwide credit union movement is represented by regional confederations and national organizations within the World Council of Credit Unions.
