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.). Borrowing rate for the credit union is a source of income to cover the administrative costs. All excess funds are returned to members in the form of dividends on savings. 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. Worldwide credit union movement is represented by regional confederations and national organizations within the World Council of Credit Unions.
