Borrowing rate for the credit union is a source of income to cover the administrative costs. All excess funds are returned to members in the form of dividends on savings. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. Credit cooperatives and credit unions exist in many different forms. The main differences relate to the nature of the membership and the opening of a credit institution. Worldwide credit union movement is represented by regional confederations and national organizations within the World Council of Credit Unions.
