adjusted income, page-7

Its project based, not company based and some projects have much lower upfront costs and development costs while others have high lead in costs. So how much they pay is not dependent on the company, but on how profitable a project is.

Eg a $5billion dollar company with many many producing assets that have not yet broke even may well pay nothing, while a compnay that has one successful project that has covered all lead in costs and expenses will be subject to a 40% tax despite perhaps all its other projects being losses.

As far as two companies owning 50:50 of revenue in a project where one bought in later, that doesn't necessarily mean 50% of those deductible expenses have been transferred to the new half owner of revenue. The new half owner of revenue may have far fewer deductible expenses to offset against any profit.
