Shareholders in corporate organizations are basic credit unions, besides the same union can be a shareholder of several corporate organizations. 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. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. Credit unions encourage savings of citizens, setting compensation payments (interest) on savings and provide from these savings loans to their members.
