Type 1 adjustment includes temperature adjustment, out of period adjustment, nonnalization of special contracts, and adjustment made to reconcile Blocking kWh with booked kWh, 2. Includes irrigation. 3. The curtailed load is added back, since the reduction in loads due to curtailment is considered an acquisition of resources to meet the load. 4.

Schedule 19 is an optional schedule, closed to new service, for commercial and industrial customers who have space heating. Some customers, depending upon their usage characteristics, could be receiving service on either schedule 6 or 23. In the normalization process we recalculate the schedule 19 customer's monthly bill applying schedules 6 and 23 rates to see if they would have billed cheaper on either one of these two schedules. This adjustment reflects the calculated reduction in revenue for those customers who would have billed cheaper on schedules 6 or 23. This adjustment also includes the annualization of the NuWest September 1, 2006 price change that occurred during the test period.

Please see page 3.3 for a breakout by customer class The removal of $31.7 million BPA credit makes up the majority of this type (1) adjustment. The bulk of the credit is being removed from the residential and irrigation customer classes. The BPA credit is also removed from expense in adjustment 5. The removal of $524 857 representing deferred revenues from two merger commitments. The first is West Valley lease, commitment no. (I 27) and the other one is administrative & general credit, commitment no. (I 31). These merger commitments are accounted for in separate regulatory adjustment numbers 5.3 and 4. The type three (3) adjustments include the proforma price change of Monsanto ($6.8m) and Irrigation tariffs contracts ($1.9m) which were effective January 1, 2007.

Amortizing the revenues, allows the Company to spread the revenue credits evenly to customers over time as they pay for the assets that provided the credits. This amortization also matches the sales of the credits to the future periods when the credits are to be used.

However, the Company has profit centers in California, Oregon, Washington and Wyoming that cross state boundaries. This adjustment correctly assigns allocation factors by tax jurisdiction code rather than by profit center. (2) Also, this adjustment corrects the allocation code on several transactions where other electric revenues were assigned situs to individual states but should be assigned a system allocation code.

Rocky Mountain Power Idaho General Rate Case Labor Escalation- December 2006 The base period, 12 months ended December 2006, and the proforma period, 12 months ended December 2007, labor expenses are summarized on page 4.2. The following is an explanation of the procedures used to develop the proforma labor expenses. 1. Actual December 2006 total labor related expenses are identified on page 4., including bare labor, incentive, other labor, pensions, benefits, and payroll taxes. 2. Actual December 2006 expenses for regular time, overtime , and premium pay were identified by labor group and annualized to reflect wage increases during the base period (see pages 4.3 and 4.5.4). 3. The annualized December 2006 regular time, overtime, and premium pay expenses were then escalated prospectively by labor group to December 2007 (see pages 4.5.4 and 4.5). Union costs were escalated using the contractual rates found on page 4.6. Non-union costs were not escalated in 2007 because the increase will not be effective until December 26 2007. 4. Non-union incentive payments were provided by the Human Resources department and were calculated based on the calendar year 2007 projections. Union employees do not participate in the Company s annual incentive program; instead , they receive annual increases to their wages that are reflected in the escalation described above. 5. Proforma December 2007 pension and employee benefits expenses were provided by the Human Resource department. These expenses can be found on page 4.2 and page 4.8. The proforma payroll tax calculations can be found on page 4., along with the wage amounts used in the calculation. December 2006 Wage 80.

Description of Adjustment: This adjustment replaces the actuarially determined pension expense for calendar year 2006 with the actual amount funded (cash basis). The Commission has recently ordered other in-state electric utilities to include the cash contributions for pension funding in rates rather than the corresponding FAS 87 expense. Refer to Order Nos. 29602 (A VU-04-01) and 29505 (IPC-03-13). The Company would prefer to include FAS 87 expense in rates, and does so for the other states it serves. However, given the Commission s direction in other cases, the Company has adjusted its expense to the level of cash contributions in the test year.

Description of Adjustment: The company committed to hold customers harmless for costs that were previously assigned to affiliates relating to management fees and set the total company amount at $1 ,500 000. This commitment is offsettable to the extent PacifiCorp demonstrates to the Commission s satisfaction that Corporate allocations from MEHC to PacifiCorp included in PacifiCorps rates are less than $7.3 million. Since this is the case for calendar year 2006, no adjustment is necessary. The company also committed to hold customers harmless for costs that were previously direct billed to affiliates.

As a result of this accounting period closing change, there are two (2) year end closing tax provision true-ups recorded during the twelve months ended December 2006 period. The first year end tax true-up was for the twelve (12) months ended March 2006. The second tax true-up was for the nine (9) months ended December 2006. This adjustment removes the April through December 2005 portion of the March 2006 true-up from results, leaving the calendar year ended December 2006 in results. These true-ups were recorded as permanent differences, therefore there was no impact to deferred income tax expense.
