Typically, donor contributions to the credit unions are targeted and used in the same statutory requirements and restrictions as the Mutual Financial Aid fund as a whole. 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). Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. 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 main advantage of credit unions consists in transparency, controllability, governance for shareholders. As of the January 1, 2012 the national associations and confederations unite more than 196 million members participating in the 51,013 credit unions in 100 countries. 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. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.). Unlike banks credit unions limit their activities to a closed circle of people.
