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. Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the credit union. The right to use the services of the credit union have only its members. Credit unions historically formed as a special form of social support, initially taken upon themselves the social mission of protecting the interests of citizens in the field of financial services. A credit union on its own initiative order is created by citizens (individuals) to solve their financial problems that they could not solve in other financial institutions.
