Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. 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. 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. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. Today, the World Council of Credit Unions is represented as members four regional confederations and twelve national associations.
