Like any financial institution, credit unions have the financial resources. Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. 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. Credit unions historically formed as a special form of social support, initially taken upon themselves the social mission of protecting the interests of citizens in the field of financial services. To increase the number of credit unions in 1979 was adopted the corresponding law that serves as the legal basis of their activity.
