At the organization of the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Credit union services are available only to its shareholders. 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. 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. Credit unions, like today's credit unions, emerged in the 19th century in Germany as a result of crop failure and famine. Credit unions are financial institutions, financial cooperatives of citizens, and in this capacity they are above all associations of people, not unification of capitals, which is typical, for example, for public companies. Today, the World Council of Credit Unions is represented as members four regional confederations and twelve national associations.
