The Alaska Native Regional Corporations (Alaska Native Corporations or ANCSA Corporations) were established in 1971 when the United States Congress passed the Alaska Native Claims Settlement Act (ANCSA) which settled land and financial claims made by the Alaska Natives and provided for the establishment of 13 regional corporations to administer those claims.
Under ANCSA the state was originally divided into twelve regions, each represented by a "Native association" responsible for the enrollment of past and present residents of the region. Individual Alaska Natives enrolled in these associations, and their village level equivalents, were made shareholder in the Regional and Village Corporations created by the Act. The twelve for-profit regional corporations, and a thirteenth region representing those Alaska Natives who were no longer residents of Alaska in 1971, were awarded the monetary and property compensation created by ANCSA. Village corporations and their shareholders received compensation through the regional corporations. The fact that many ostensibly Alaska Native villages throughout the state were not empowered by the ANCSA to form village corporations later led to a number of lawsuits.
The regional and village corporations are now owned by Alaska Native people through privately owned shares of corporation stock. Alaska Natives alive at ANCSA's enactment on December 17, 1971, who enrolled in a Native association (at the regional and/or village level) received 100 shares of stock in the respective corporation. In 2006, the 109th Congress passed S.449 which amended ANCSA, and allowed for shares to be more easily issued to those who had missed the enrollment, or were born after the enrollment period by reducing the requirement for voting from a majority of shareholders to a majority of attending shareholders at corporation meetings.
During the 1970s, ANCSA regional and village corporations selected land in and around native villages in the state in proportion to their enrolled populations. Village corporations own the surface rights to the lands they selected, but regional corporations own the subsurface rights of both their own selections and of those of the village corporations.
