What the rebuild surfaced. The study states two tax rates and a US$117.2M total, but no depreciation method, depletion or loss treatment. Its 17.8% effective tax burden against a 27.0% combined rate needs deductions it names only as 'various tax pool balances'. Built from federal and Oregon statute, the rebuild lands 2.6% below the headline and within 0.6% pre-tax; with the study's implied deduction selected, it is within 0.5%.
