Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. 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. 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. The relationship of shareholders with credit union are not client-based, they are co-operative, based on different principles and standards, in particular, on the principles of the law of obligations. Until the mid-XX century, credit unions in the United States had little assets that did not exceed, as a rule, 100 thousand dollars Credit unions appeared in England in the 19th century. In 1844 a group of workers from Rochdale established the first cooperative. Credit cooperatives and credit unions exist in many different forms. The main differences relate to the nature of the membership and the opening of a credit institution. The specifics of credit unions and, in some sense, their uniqueness lies in the fact that they work not for profit and do not appropriate profit. Credit union as a consumer cooperative operates on the principles of equality of all its members.
