Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. 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. 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. 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. Membership in the credit union forms responsible citizens and conscientious attitude to their obligations as a norm of behavior, identify the value of a decent man's reputation in the business turnover. 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. A credit union on its own initiative order is created by citizens (individuals) to solve their financial problems that they could not solve in other financial institutions.
