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. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. 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. Credit unions are financial institutions, financial cooperatives of citizens, and in this capacity they are above all associations of people, not unification of capitals, which is typical, for example, for public companies. Credit unions base their activities on savings of shareholders, their shares and savings contributions, which make up the fund of mutual financial assistance - a source of cash loans to shareholders. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.).
