Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. The number of shareholders of a credit union is limited and formalized by a list. Limit of the number is defined by the assembly and such assembly establishes the charter. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. In the UK, credit unions are a source of financing of people groups. This tool is not widely used. Credit unions are financial institutions, financial cooperatives of citizens, and in this capacity they are above all associations of people, not unification of capitals, which is typical, for example, for public companies. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.).
