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. 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. Until the mid-XX century, credit unions in the United States had little assets that did not exceed, as a rule, 100 thousand dollars Taking a decision to join a credit union, citizens create an organization through which they participate in the shared savings by mutual crediting and joint (collective) use of personal savings. 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. Corporate alliances are intermediaries between credit unions and financial markets.
