There were laws set in place ,so that our government could not come in and change the PFD rules, at any time. The shareholders of the fund are the only ones that can vote on this. Period! This means all of those whom qualify for a check, not the Senate, House or Legislators!
If no one touches the principle , the Dividends, may not go up, but they would still come in. We the people of AK, make that decision, not our government. Wake up people... They have tried this several times before. If we let them do this, they will continue to do so, until it's gone. Don't let "gov" speak deceive you! 
I have not personally read all the ins and out of this, but  in the Juneau paper article: 
( My Turn: The Permanent Fund Dividend in jeopardy, Pt. 1 | Juneau Empire - Alaska's Capital City Online Newspaper )
, you can see for yourself. Maybe I'm missing something...
