Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). Credit unions encourage savings of citizens, setting compensation payments (interest) on savings and provide from these savings loans to their members. 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. Share contributions are transferred to the credit union on the basis of membership for the whole stay of a shareholder as member of the credit union and are the basis of membership. 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. Initially, the target groups of credit unions were farmers (Raiffeisen), and now they include both individuals (credit unions), and organizations. Consumer loan and reliable savings - these are the main goals, which mean "natural persons" having decided to unite in credit consumer cooperative. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the credit union.
