Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. Credit union is created by a group of members who pursue a common interest. Agreeing to make regular contributions, they create a fund from which can borrow money for investments and replenishment of working capital at favorable interest rates. In the U.S. credit unions timely and full repayment of loans is a common phenomenon. Unpaid and delinquent loans are not more than 3% of their amount. 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. Credit union services are available only to its shareholders. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. Credit unions are competitors of savings institutions, adding interest on deposits of members. This applies to the shares, as well as to additional funds transferred to the account in the credit union. 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. The right to use the services of the credit union have only its members.
