Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. 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. Credit unions encourage savings of citizens, setting compensation payments (interest) on savings and provide from these savings loans to their members. The uniqueness of credit unions is that they put together the principles and benefits of financial cooperatives, consumer cooperatives and mutual aid funds, born once by trade unions. First central bank of credit unions appeared in 1876. Credit unions began to appear rapidly in many European countries. At the organization of the credit union it is important that people know each other and know the extent to which each of them is trustworthy. 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. 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.
