 Alaska residents also receive annual dividend payments from the state's Permanent Fund, based on a five-year average of the fund's performance. The state established the Permanent Fund in 1976, as construction of the Alaska Pipeline concluded. Twenty-five percent of revenue from mineral leases on state-owned lands and from federal mineral revenue-sharing payments go into the Permanent Fund for investment. In 2016, each Alaska resident received $1,022 as a result of this payout, down from $2,072 in 2015 and just below the ten-year average of $1,424.[^27]
