To date, credit unions - virtually the only form of financial institution where people can quickly and without any problems get a relatively inexpensive cash loan. Credit unions encourage savings of citizens, setting compensation payments (interest) on savings and provide from these savings loans to their members. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. The relationship of shareholders with credit union are not client-based, they are co-operative, based on different principles and standards, in particular, on the principles of the law of obligations. Credit unions historically formed as a special form of social support, initially taken upon themselves the social mission of protecting the interests of citizens in the field of financial services. Unlike banks credit unions limit their activities to a closed circle of people.
