At the organization of the credit union it is important that people know each other and know the extent to which each of them is trustworthy. 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. Is necessary that all shareholders of the credit union were members of a single community, would know each other well enough to enjoy mutual trust. Credit unions of the open type are still controlled by their members, but at the same time provide services to people who are not its members (external customers). 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.
