10. Income Taxes

The differences between Park and ORA's estimates of Income Tax are based on differences in estimates of factors resolved elsewhere in this decision, including Operating Expense and Taxes Other Than Income. Both parties use the same methodology to calculate interest deduction - weighted cost of long-term debt multiplied by the rate base. The differences in Interest Expense are due to differences in rate base estimates. These adjustments have been made in the attached appendices. Similarly, the differences in Park and ORA's estimates of Tax Depreciation are due solely to the remaining differences between the parties' estimate of utility plan in the test years. That adjustment has been made in the attached appendices.
