Like any financial institution, credit unions have the financial resources. Most modern credit unions represent specialized consumer cooperatives of citizens associated by the principle of social community: place of work, place of residence, profession, or any other shared interest. Borrowing rate for the credit union is a source of income to cover the administrative costs. All excess funds are returned to members in the form of dividends on savings. 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). In the U.S. credit unions timely and full repayment of loans is a common phenomenon. Unpaid and delinquent loans are not more than 3% of their amount. 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). 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. Historically, credit unions have grown from the experience of credit cooperatives, but they took the experience of organizations of mutual aid of citizens by moving methods of social self-protection from labor and toward consumption. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others.
