In the U.S., credit unions have a clear organizational structure. All credit unions belong to one or the other parent credit union (there are 35 of them in the U.S.). 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 economic basis of credit unions - finances of a household. The main objective of the credit union - to ensure financial stability of a household, to ensure the priority of their shareholders' financial interests. Taking a decision to join a credit union, citizens create an organization through which they participate in the shared savings by mutual crediting and joint (collective) use of personal savings. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. 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. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the credit union.
