Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). 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. Credit unions encourage savings of citizens, setting compensation payments (interest) on savings and provide from these savings loans to their members. Credit union is created by a group of members who pursue a common interest. Agreeing to make regular contributions, they create a fund from which can borrow money for investments and replenishment of working capital at favorable interest rates. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. 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 unions appeared in England in the 19th century. In 1844 a group of workers from Rochdale established the first cooperative. Standards by which credit unions build their work do not coincide with the standards and regulations of consumer cooperation of the usual type.
