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.). Like any financial institution, credit unions have the financial resources. Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. Income received by the credit union shall be distributed among the shareholders or spent for the depreciation of services, that is, are the most effective means of meeting the needs of shareholders. 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. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. Standards by which credit unions build their work do not coincide with the standards and regulations of consumer cooperation of the usual type. Credit cooperatives and credit unions exist in many different forms. The main differences relate to the nature of the membership and the opening of a credit institution.
