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. 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. Until the mid-XX century, credit unions in the United States had little assets that did not exceed, as a rule, 100 thousand dollars Standards by which credit unions build their work do not coincide with the standards and regulations of consumer cooperation of the usual type. Worldwide credit union movement is represented by regional confederations and national organizations within the World Council of Credit Unions.
