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). Credit union promotes the effective conservation of personal funds of its members, giving them the loans from the funds of the credit union, as well as the sharing of savings in education, housing, health care and other programs of social support and social development of its members. At the organization of the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Until the 70's there was a proliferation of the U.S. credit unions due to the increase of their number and the number of shareholders, although it must be acknowledged that there was also and a qualitative growth. 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. Unlike banks, in order to use the services of a credit union, you have to become its member, having written an application and having paid thus shares and membership fee. Corporate alliances are intermediaries between credit unions and financial markets. 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.
