Activity of the credit union consists of organizing mutual financial assistance by meeting the needs of its members in the services of saving and obtaining loans. 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. The specifics of credit unions and, in some sense, their uniqueness lies in the fact that they work not for profit and do not appropriate profit. Corporate alliances are intermediaries between credit unions and financial markets.
