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. The uniqueness of credit unions is that they put together the principles and benefits of financial cooperatives, consumer cooperatives and mutual aid funds, born once by trade unions. First central bank of credit unions appeared in 1876. Credit unions began to appear rapidly in many European countries. 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. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.).
