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. Today in the UK there are about 700 credit unions with assets exceeding 200 million pounds. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. 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. Contributions from of shareholders in credit unions in no way can be considered as borrowed funds, they come from the shareholders and for the shareholders and can not be used to provide services to third parties. 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.). Today, the World Council of Credit Unions is represented as members four regional confederations and twelve national associations.
