Fund of Mutual Financial Aid of the credit union can be extended by sponsorship contributions from businesses, organizations, including on a returnable basis. Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. 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). The number of shareholders of a credit union is limited and formalized by a list. Limit of the number is defined by the assembly and such assembly establishes the charter. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. 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). Consumer loan and reliable savings - these are the main goals, which mean "natural persons" having decided to unite in credit consumer cooperative. A credit union on its own initiative order is created by citizens (individuals) to solve their financial problems that they could not solve in other financial institutions.
