Like any financial institution, credit unions have the financial resources. Most modern credit unions represent specialized consumer cooperatives of citizens associated by the principle of social community: place of work, place of residence, profession, or any other shared interest. 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. First Credit Union was savings unprofitable institution, or rather credit cooperative, providing services to its members. The difference between credit unions and banks is clearly is apparent when comparing the structure of assets and liabilities of credit unions and banks. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. Historically, credit unions have grown from the experience of credit cooperatives, but they took the experience of organizations of mutual aid of citizens by moving methods of social self-protection from labor and toward consumption. 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. To increase the number of credit unions in 1979 was adopted the corresponding law that serves as the legal basis of their activity. Corporate alliances are intermediaries between credit unions and financial markets.
