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. 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. 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. Like the credit cooperatives, credit unions form associations of a higher level, which are called corporate credit unions. 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). The value of credit unions is not limited to the role of the economic agent - they are an important element of the social structure and a factor of social stability and progress. In the UK, credit unions are a source of financing of people groups. This tool is not widely used.
