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. National Credit Union Insurance Fund was created by Congress in 1970 to insure deposits of credit union members in the amount of 100 thousand dollars. Shareholders in corporate organizations are basic credit unions, besides the same union can be a shareholder of several corporate organizations. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. To increase the number of credit unions in 1979 was adopted the corresponding law that serves as the legal basis of their activity.
