To get a loan in the credit union a shareholder must be not only a formally adopted there, but necessary pay in cash contributions, the amount and order of payment of which approved by the General Assembly and fixed by the charter. Typically, donor contributions to the credit unions are targeted and used in the same statutory requirements and restrictions as the Mutual Financial Aid fund as a whole. Is necessary that all shareholders of the credit union were members of a single community, would know each other well enough to enjoy mutual trust. 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. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. In the UK, credit unions are a source of financing of people groups. This tool is not widely used. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.).
