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. Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. Share contributions are transferred to the credit union on the basis of membership for the whole stay of a shareholder as member of the credit union and are the basis of membership. 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. 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. Important specifics of creating a credit union - an initiative order of organization: people do not receive any instructions, orders or regulations, the unification into a credit union occurs by their will and decision. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. In the UK, credit unions are a source of financing of people groups. This tool is not widely used. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.). Unlike banks credit unions limit their activities to a closed circle of people.
