Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. 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. Until the mid-XX century, credit unions in the United States had little assets that did not exceed, as a rule, 100 thousand dollars In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. Unlike banks credit unions limit their activities to a closed circle of people.
