reduces the overall revenue requirement by $2.4 71 million.
b. Revise Net Rate Base. Reflects adjustments to net rate base to: 1) update information
related to 2016 capital additions ; 2) remove adjustments proposed by the Company
for Plant Held For Future Use and 2017 capital additions, including related
depreciation expense, as well as the impact on Accumulated Depreciation and
Accumulated Deferred Federal Income Taxes; and 3) remove agreed-upon amount
related to Asset Management Transmission project. This adjustment reduces the
overall revenue requirement by $ I .329 million and reduces net rate base by $740,000.
c. Revise Deferred Debits and Credits. Revises the deferred debits and credits
regulatory balances to reflect corrected balances as of December 2016, rather than the
2017 balances as proposed by the Company. This adjustment decreases the overall
revenue requirement by $62,000 and increases rate base by $107,000.
d. Remove 2017 Non-Union Labor Expenses -This adjustment reduces the overall
revenue requirement by $310,000, by removing 2017 incremental non-union labor
expenses.

expenses. Includes $210,000 of amortization expense representing the customer
portion ($630,000) to recover for regulatory purposes over the period 2017-2019.
This adjustment reduces the overall revenue requirement by $1.057 million.

Purchase Agreement net expenses from base power supply expense. The Parties
agree that, for purposes of this case, the recovery of costs related to the Palouse Wind
Power Purchase Agreement ("PPA") will continue to be included in the PCA, subject
to the current sharing (90% customer, 10% Company). This adjustment decreases the
overall revenue requirement by $4.509 million.

general (A&G) expenses related to: I) removing additional Board of Director
expenses included in 2015 ($ I 59,000); 2) removing legal expenses allocated to Idaho

baseline values for the electric fixed cost adjustment mechanism resulting from the January I,
2017 settlement revenue requirement are detailed in Appendix B.
C. COST OF SERVICE/RATE SPREAD/RATE DESIGN/LOW INCOME
I 0. Cost of Service. For electric operations, the Company prepared an analysis using
a system load factor peak credit method of classifying production costs, allocating 100% of
transmission costs to demand , and allocating transmission costs on a twelve-month coincident
peak allocation factor. For settlement purposes, the Parties agreed to use a pro-rata allocation
based on the Company's proposed 25% move towards unity for purposes of spreading the
revised electric revenue requirement, while not agreeing to any particular cost of service
methodology.
11. Rate Spread/Rate Design (Base Rate Changes). As indicated above, the Parties
agreed that the increase in base revenues would be spread to all electric rate schedules on a pro­
rata allocation of the Company's rate spread percentages from its original filing.
12. Electric Rate Design. With the exception of the Residential Basic Charge, the
Parties agree to the rate design changes proposed by the Company in Mr. Ehrbar's direct
testimony. For the electric Residential Basic Charge (Schedule 1 ), the Parties agreed that it will
increase from $5.25 per month to $5.75 per month, an increase of $0.50 per month. Appendix C
provides a summary of the current and revised rates and charges (as per the Settlement) for
electric service.

next general rate case filing, to meet and confer regarding the Company's electric cost of service
study. Included in the workshop(s) would be discussion related to the methodologies used by
A vista to classify and allocate its costs, as we ll as a review of the changes that occurred between
the cost of service study results from the Company's 2015 general rate case filing and its 2016
general rate case filing.
The Company will provide available information, studies and data requested by a Party
so as to enable meaningful workshop participation and discussion of issues.

contest cost of service and rate spread issues in subsequent proceedings.

meet and confer prior to the Company's next general rate filing in order to assess the Low
