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. The economic basis of credit unions - finances of a household. The main objective of the credit union - to ensure financial stability of a household, to ensure the priority of their shareholders' financial interests. Credit union is created by a group of members who pursue a common interest. Agreeing to make regular contributions, they create a fund from which can borrow money for investments and replenishment of working capital at favorable interest rates. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. Historically, credit unions have grown from the experience of credit cooperatives, but they took the experience of organizations of mutual aid of citizens by moving methods of social self-protection from labor and toward consumption. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. Corporate alliances are intermediaries between credit unions and financial markets.
