When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. 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 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.
