Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. 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. Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. Credit unions encourage savings of citizens, setting compensation payments (interest) on savings and provide from these savings loans to their members. Credit union is created by a group of members who pursue a common interest. Agreeing to make regular contributions, they create a fund from which can borrow money for investments and replenishment of working capital at favorable interest rates. 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. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings.
