National Credit Union Administration (NCUA) - an independent federal agency, based in Washington (State of Columbia), established by the U.S. Congress to oversee the federal credit union system. Credit unions also differ from the traditional consumer cooperatives. The number of shareholders of a credit union is limited and formalized by a list. Limit of the number is defined by the assembly and such assembly establishes the charter. 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. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the credit union. The value of credit unions is not limited to the role of the economic agent - they are an important element of the social structure and a factor of social stability and progress. In the UK, credit unions are a source of financing of people groups. This tool is not widely used. Credit union as a consumer cooperative operates on the principles of equality of all its members.
