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 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. Members of credit unions place in credit unions usually free fund balances, ie those that remain after expenses devoted to education of children, the acquisition of new properties, additional pension benefits, etc. 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. Shareholders in corporate organizations are basic credit unions, besides the same union can be a shareholder of several corporate organizations. In the UK, credit unions are a source of financing of people groups. This tool is not widely used.
