The Alaska Department of Revenue, Permanent Fund Dividend Division is responsible for determining applicant eligibility for the distribution of an annual dividend that is paid to Alaska residents from investment earnings of mineral royalties. The annual payment allows for Alaskans to share in a portion of the State minerals revenue in the form of a dividend to benefit current and future generations. Eligibility to receive a Permanent Fund Dividend is defined by the Alaska Legislature through Statute and Regulation. The dividend calculation is based on the number of eligible Alaskan applicants in a dividend year and half of the statutory net income averaged over the five most recent fiscal years. The available funds are also reduced by prior-year dividend obligations, PFD operation expenses, and other state agency program appropriations. The Alaska Permanent Fund Corporation is responsible for investment of the fund's principal balance.
