Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). Like any financial institution, credit unions have the financial resources. 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). Is necessary that all shareholders of the credit union were members of a single community, would know each other well enough to enjoy mutual trust. At the organization of the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Credit union services are available only to its shareholders. 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. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. Credit unions are competitors of savings institutions, adding interest on deposits of members. This applies to the shares, as well as to additional funds transferred to the account in the credit union. U.S. credit unions have another significant difference from the credit cooperatives of farmers: the first have major proportion of short-term loans, the second - long and mostly in real estate.
