Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. 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 main advantage of credit unions consists in transparency, controllability, governance for shareholders. Contributions from of shareholders in credit unions in no way can be considered as borrowed funds, they come from the shareholders and for the shareholders and can not be used to provide services to third parties.
