Representative organization, leading the coordination work in the field of development of both global and national credit union movement is the World Council of Credit Unions (WOCCU) established in 1971 (headquartered in Madison, USA). Some credit unions are closed, serving only their members. However, the more and more popularitywin cooperatives of open type. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. In the UK, credit unions are a source of financing of people groups. This tool is not widely used. Standards by which credit unions build their work do not coincide with the standards and regulations of consumer cooperation of the usual type. The right to use the services of the credit union have only its members. Credit unions historically formed as a special form of social support, initially taken upon themselves the social mission of protecting the interests of citizens in the field of financial services. Corporate alliances are intermediaries between credit unions and financial markets.
