In the U.S., credit unions have a clear organizational structure. All credit unions belong to one or the other parent credit union (there are 35 of them in the U.S.). 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. 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. 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. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. 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.
