Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. Borrowing rate for the credit union is a source of income to cover the administrative costs. All excess funds are returned to members in the form of dividends on savings. Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. First central bank of credit unions appeared in 1876. Credit unions began to appear rapidly in many European countries. Until the 70's there was a proliferation of the U.S. credit unions due to the increase of their number and the number of shareholders, although it must be acknowledged that there was also and a qualitative growth. Over 30% of the assets of credit unions are investments in government securities, certificates of deposit of banks and savings loan associations, as well as in the parent credit unions, and other risk-free investments. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. Credit unions base their activities on savings of shareholders, their shares and savings contributions, which make up the fund of mutual financial assistance - a source of cash loans to shareholders. 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. Worldwide credit union movement is represented by regional confederations and national organizations within the World Council of Credit Unions.
