Shortly after the oil from Alaska's North Slope began flowing to market through the Trans-Alaska Pipeline System, the Permanent Fund was created by an amendment to the Alaska Constitution. It was designed to be an investment where at least 25% of the oil money would be put into a dedicated fund for future generations, who would no longer have oil as a resource. This does not mean the fund is solely funded by oil revenue. The Fund includes neither property taxes on oil company property nor income tax from oil corporations, so the minimum 25% deposit is closer to 11% if those sources were also considered.[Context?] The Alaska Permanent Fund sets aside a certain share of oil revenues to continue benefiting current and all future generations of Alaskans. Many citizens also believed that the legislature too quickly and too inefficiently spent the $900 million bonus the state got in 1969 after leasing out the oil fields. This belief spurred a desire to put some oil revenues out of direct political control.
