This additional tax was SP's baby and was layered on top of the royalties and other existing fees. It was an aggressive progressive tax on net profits.
According to industry officials it brought Alaska's share of revenue (revenue - not profits) up to 75%.
Part of the revenue derived from this additional tax did go to Alaskans in the form of a check. But, and this is key, this was not an agreed upon quid pro quo driven royalty...it was a levied tax and as with any tax those entities paying had no say in the matter.
To take it a step further, it was a tax (confiscation) of corporate revenues for the purpose of re-distribution.
