Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). To date, credit unions - virtually the only form of financial institution where people can quickly and without any problems get a relatively inexpensive cash loan. 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. 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. Since the early 80's started the process of consolidation of credit unions, leading to a decrease in their number with a simultaneous increase in the total number of members. 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.
