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. Credit unions also differ from the traditional consumer cooperatives. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. The relationship between credit unions and shareholders arise from the membership and are not customer relationship.
