I didn't see anything in there about a change in the payment schedule. It does look like the high price of oil pushed the payments to a higher percentage. The idea of the Alaska method is that the oil belongs to the residents of the state, not to the oil companies. For pumping the oil the oil companies get to keep some of the money and have to pay some of it to Alaska. Hey, if I had a big puddle of oil underneath my land, I would try to get a similar payment plan - I get at least some of the increase of value of _my_ oil if the world price goes up. It would be pretty stupid to sell it to the oil company many years in advance for a fixed price per barrel.
This isn't done anywhere I know and it wasn't done it Alaska. It was a percentage that already went up when the prices went up, both for royalties and again for taxes on profits. Palin's administration then raised the percentage and made the change retroactive.
Right I noticed that after I had posted it...sorry...I think it was from Monday.
