Membership in the credit union is voluntary and is open to all citizens bound by with joint work or residence, who wished to create a credit union to use its services and are willing to take on relevant commitments and responsibilities. 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. Principles of cooperative democracy and interaction were adequate to the purposes for which people joined credit unions. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. 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 value of credit unions is not limited to the role of the economic agent - they are an important element of the social structure and a factor of social stability and progress. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.). Unlike banks credit unions limit their activities to a closed circle of people. 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.
