Today in the UK there are about 700 credit unions with assets exceeding 200 million pounds. Credit unions of the open type are still controlled by their members, but at the same time provide services to people who are not its members (external customers). International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. Initially, the target groups of credit unions were farmers (Raiffeisen), and now they include both individuals (credit unions), and organizations. 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. The supreme body of the World Council of Credit Unions is the Assembly, which elects the president and the board of directors of WOCCU. The right to use the services of the credit union have only its members. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.). 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.
