Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. 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.). Credit unions encourage savings of citizens, setting compensation payments (interest) on savings and provide from these savings loans to their members. Credit union promotes the effective conservation of personal funds of its members, giving them the loans from the funds of the credit union, as well as the sharing of savings in education, housing, health care and other programs of social support and social development of its members. 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. Credit unions of the open type are still controlled by their members, but at the same time provide services to people who are not its members (external customers). 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. On the consumer credit market in the U.S. credit unions are on the third place after the commercial banks and finance companies and are ahead of savings institutions, not taking into account the loans on real estate. Credit Union - one of the most attractive financial institutions for the public being a non-profit alternative to banks.
