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.). National Credit Union Administration (NCUA) - an independent federal agency, based in Washington (State of Columbia), established by the U.S. Congress to oversee the federal credit union system. 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. Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. 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. Contributions from of shareholders in credit unions in no way can be considered as borrowed funds, they come from the shareholders and for the shareholders and can not be used to provide services to third parties. Worldwide credit union movement is represented by regional confederations and national organizations within the World Council of Credit Unions.
