To date, credit unions - virtually the only form of financial institution where people can quickly and without any problems get a relatively inexpensive cash loan. The difference between credit unions and banks is clearly is apparent when comparing the structure of assets and liabilities of credit unions and banks. 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. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. 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. U.S. credit unions have another significant difference from the credit cooperatives of farmers: the first have major proportion of short-term loans, the second - long and mostly in real estate. The specifics of credit unions and, in some sense, their uniqueness lies in the fact that they work not for profit and do not appropriate profit.
