Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. Activity of the credit union consists of organizing mutual financial assistance by meeting the needs of its members in the services of saving and obtaining loans. 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. The difference between credit unions and banks is clearly is apparent when comparing the structure of assets and liabilities of credit unions and banks. When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Credit union promotes the effective conservation of personal funds of its members, giving them the loans from the funds of the credit union, as well as the sharing of savings in education, housing, health care and other programs of social support and social development of its members. 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. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. Unlike banks, in order to use the services of a credit union, you have to become its member, having written an application and having paid thus shares and membership fee.
