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). Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. The supreme body of the World Council of Credit Unions is the Assembly, which elects the president and the board of directors of WOCCU. U.S. credit unions have another significant difference from the credit cooperatives of farmers: the first have major proportion of short-term loans, the second - long and mostly in real estate.
