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 encourage savings of citizens, setting compensation payments (interest) on savings and provide from these savings loans to their members. 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. Credit unions of the open type are still controlled by their members, but at the same time provide services to people who are not its members (external customers). Historically, credit unions have grown from the experience of credit cooperatives, but they took the experience of organizations of mutual aid of citizens by moving methods of social self-protection from labor and toward consumption. Unlike banks credit unions limit their activities to a closed circle of people. Credit Union - one of the most attractive financial institutions for the public being a non-profit alternative to banks.
