PDFs do come from state funding. All AS 43.23.045 says is it's a separate fund, but that doesn't mean it can't be spent on for government. Statutes can be changed.

(a) The dividend fund is established as a separate fund in the state treasury. The dividend fund shall be administered by the commissioner and shall be invested by the commissioner in the same manner as provided in AS 37.10.070 .
