Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. 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. Initially, the target groups of credit unions were farmers (Raiffeisen), and now they include both individuals (credit unions), and organizations. The value of credit unions is not limited to the role of the economic agent - they are an important element of the social structure and a factor of social stability and progress. 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. Credit unions are financial institutions, financial cooperatives of citizens, and in this capacity they are above all associations of people, not unification of capitals, which is typical, for example, for public companies. Credit unions base their activities on savings of shareholders, their shares and savings contributions, which make up the fund of mutual financial assistance - a source of cash loans to shareholders. Credit Union - one of the most attractive financial institutions for the public being a non-profit alternative to banks.
