Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). Principles of cooperative democracy and interaction were adequate to the purposes for which people joined credit unions. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. Members of credit unions place in credit unions usually free fund balances, ie those that remain after expenses devoted to education of children, the acquisition of new properties, additional pension benefits, etc. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. Initially, the target groups of credit unions were farmers (Raiffeisen), and now they include both individuals (credit unions), and organizations. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. Credit Union - a non-profit financial institution specialized in mutual financial assistance by providing savings and credit services to their members. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.).
