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). Like the credit cooperatives, credit unions form associations of a higher level, which are called corporate credit unions. Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. Since the early 80's started the process of consolidation of credit unions, leading to a decrease in their number with a simultaneous increase in the total number of members. Membership in the credit union forms responsible citizens and conscientious attitude to their obligations as a norm of behavior, identify the value of a decent man's reputation in the business turnover. 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. Contributions from of shareholders in credit unions in no way can be considered as borrowed funds, they come from the shareholders and for the shareholders and can not be used to provide services to third parties. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.).
