Activity of the credit union consists of organizing mutual financial assistance by meeting the needs of its members in the services of saving and obtaining loans. Like the credit cooperatives, credit unions form associations of a higher level, which are called corporate credit unions. Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. 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. 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. 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.
