MONTANA-DAKOTA UTILITIES CO.
Before the Public Service Commission of Wyoming
Docket No. 30013-351-GR-19
Direct Testimony of
Nicole A. Kivisto
Q. Please state your name and business address. 1
A. My name is Nicole A. Kivisto and my business address is 400 North 2
Fourth Street, Bismarck, North Dakota 58501. 3
Q. By whom are you employed and in what capacity? 4
A. I am the President and Chief Executive Officer (CEO) of Montana-5
Dakota Utilities Co. (Montana-Dakota), Cascade Natural Gas Corporation 6
and Intermountain Gas Company, subsidiaries of MDU Resources Group, 7
Inc. as well as Great Plains Natural Gas Co., a division of Montana-8
Dakota, collectively the MDU Utilities Group. 9
Q. Have you testified in other proceedings before regulatory bodies? 10
A. Yes. I have previously presented testimony before this Commission, 11
the Public Service Commissions of Montana and North Dakota, the Public 12
Utilities Commissions of Idaho, Minnesota and South Dakota, the Public 13
Utility Commission of Oregon, and the Washington Utilities and 14
Transportation Commission. 15
Q. Please describe your duties and responsibilities with Montana-16
Dakota. 17
2
A. I have executive responsibility for the development, coordination, 1
and implementation of strategies and policies relative to operations of the 2
above mentioned companies that, in combination, serve over one million 3
customers in eight states. 4
Q. Please outline your educational and professional background. 5
A. I hold a Bachelor’s Degree in Accounting from Minnesota State 6
University Moorhead. I began working for MDU Resources/Montana-7
Dakota in 1995 and have been in my current capacity since January 2015. 8
I was the Vice President-Operations of Montana-Dakota and Great Plains 9
from January of 2014 until assuming my present position. 10
Prior to that, I was the Vice President, Controller and Chief 11
Accounting Officer for MDU Resources for nearly four years and held 12
other finance related positions prior to that. 13
Q. What is the purpose of your testimony? 14
A. The purpose of my testimony is to provide an overview of the 15
Company’s Wyoming natural gas operations, explain the Company’s 16
request for a natural gas distribution rate increase and discuss the policies 17
and reasons underlying the major aspects of the request. I will also 18
introduce the other Company witnesses that will present testimony and 19
exhibits in further support of the Company’s request. 20
Q. Would you provide a summary of Montana-Dakota's gas operations 21
in Wyoming? 22
3
A. Montana-Dakota provides natural gas service to approximately 1
19,059 customers in nine communities, operating approximately 656 miles 2
of distribution mains and approximately 19,600 services. The customer 3
base is 87 percent residential and 13 percent commercial and industrial. 4
As of December 31, 2018, the Company had 31 full and part time 5
employees who live and work throughout the Wyoming service area. 6
Montana-Dakota's Wyoming district office is located in Sheridan, 7
Wyoming. Additionally, there are gas related service technicians and 8
construction employees headquartered in Lovell and Powell. A gas 9
service technician is also located in Buffalo. In addition to Sheridan, these 10
three Wyoming communities are deemed strategic to the safe and reliable 11
operation of the Company’s natural gas distribution system. 12
Service technicians and construction employees in Montana, North 13
Dakota and South Dakota support operations in Wyoming communities as 14
needed. A map of the gas distribution system in Wyoming is included as 15
Exhibit No. ___(NAK-1). 16
Montana-Dakota’s customers have toll-free access to the Customer 17
Service Center located in Meridian, Idaho and Bismarck, North Dakota as 18
well as the Credit Center in Bismarck, North Dakota, to place routine utility 19
service requests and inquiries from 7:00 am to 7:00 pm local time, 20
Monday through Friday and emergency calls on a 24-hour basis. A 21
scheduling center, located in Meridian, Idaho transmits electronic service 22
orders to the mobile terminals placed in our fleet of service and 23
4
construction vehicles. This network allows the Company to respond 1
quickly to customer requests and emergency situations. 2
Q. Would you please provide more information regarding the customers 3
the Company serves? 4
A. Yes. The residential, firm general service and small interruptible 5
customers use natural gas primarily for space and water heating. As 6
such, Montana-Dakota’s system has a low load factor with peak gas 7
requirements occurring during the winter. Summer loads are small by 8
comparison. The total annual natural gas used by our Wyoming 9
customers is 5,252,781 Dk as identified for the test period in this 10
proceeding. 11
The Company is proposing to discontinue the non-core revenue 12
credit wherein interruptible volumes and revenues have previously been 13
eliminated for purposes of establishing the firm core rates and the revenue 14
associated with the non-core customers is tracked and has been 15
subsequently credited to the core firm residential and general service 16
customer classes. 17
Montana-Dakota has included interruptible customers’ volumes and 18
revenues in the development of the revenue requirement in this filing. The 19
Company has experienced reasonably stable volume usage for these 20
customers in recent years and expects the current price environment 21
surrounding natural gas to continue to make natural gas an economic and 22
environmental choice for its customers well into the future. Discontinuing 23
5
the non-core credit will increase price transparency for customers and will 1
better match the recovery of costs from customers with the costs incurred 2
by the Company to serve the same customers. 3
Q. Would you please describe the basic elements that make up the total 4
costs of providing natural gas service? 5
A. For a natural gas distribution utility, the basic elements which make 6
up the cost of providing natural gas service are the cost of gas delivered at 7
the town border stations in its service territory and the cost of distributing 8
the gas from the town border station to the end use customer. It is the 9
second of these two elements, the distribution costs, which are the subject 10
of this application for a general rate increase. 11
The natural gas the Company purchases from suppliers is a 12
commodity like wheat or corn, the price of which is not regulated. The 13
cost of delivering the gas to the Company’s distribution system at the town 14
border station is regulated by the FERC or other regulatory agencies. 15
These gas costs are passed on to customers on a dollar-for-dollar basis 16
as specified in the Commission approved Purchased Gas Cost Adjustment 17
tariff. The gas portion of the cost of providing natural gas service 18
comprises about 58 percent of a typical residential bill for gas service. 19
The distribution cost portion of the Company’s cost of service is the 20
subject of this proceeding. This element includes the costs of new 21
distribution investments, replacement of aging infrastructure, operation 22
and maintenance expenses, depreciation, taxes, and the opportunity to 23
6
earn a return on the Company’s investments in facilities that provide 1
natural gas service. Distribution costs are currently about 42 percent of a 2
typical residential bill. 3
Q. Ms. Kivisto, did you authorize the filing of the rate application in this 4
proceeding? 5
A. Yes, I did. 6
Q. What is the amount of the increase requested? 7
A. As will be fully explained by other Company witnesses, the 8
Company is requesting a natural gas rate increase of $1,052,167 9
representing a 6.96 percent increase in revenues based on a 2018 test 10
year adjusted for known and measurable changes through year end 2019. 11
Q. Why has Montana-Dakota filed this application for a natural gas rate 12
increase? 13
A. Montana-Dakota is requesting an increase in its general gas rates 14
at this time because the current rates do not reflect the cost of providing 15
natural gas service to the Company’s Wyoming customers. 16
Q. When was the Company’s last general rate case? 17
A. The Company’s last rate case was Docket No. 30013-297-GR-14. 18
The resulting rate increase was $501,000, or a 2.62 percent overall 19
increase. Final rates in that case became effective on June 1, 2015. 20
Q. What are the primary reasons that Montana-Dakota needs an 21
increase at this time? 22
7
A. As noted earlier, the last rate increase was implemented June 1, 1
2015 and was based on a pro forma 2014 revenue requirement. The 2
primary reason for the need for an increase in rates is increased operating 3
expenses and Montana-Dakota's continued investment in distribution 4
facilities to improve system safety and reliability. The additional 5
investment has generally increased the associated depreciation, taxes 6
and operation and maintenance expenses. 7
Without an increase in distribution rates, the Company projects its 8
2019 rate of return will be 2.399 percent, well below its cost of capital. 9
Q. Would you please describe the investment in distribution facilities to 10
improve system safety and integrity in greater detail? 11
A. The investment in system safety and integrity is a focused effort 12
based on the Company's Distribution Integrity Management Program 13
(DIMP). The objective of the DIMP is to develop a model to assist in 14
determining which areas of the gas distribution system to focus 15
replacement, maintenance, and repair efforts and resources due to known 16
or predicted threats to the distribution system. 17
The model assesses nine different threat categories: Corrosion, 18
Natural Forces, Equipment Failure, Material Failure, Excavation Damage, 19
Incorrect Operation, Weld/Joint Failure, Outside Force, and Other all 20
equally weighted. 21
The DIMP model data was updated in 2019, as it will be each year, 22
by an internal Integrity Department group comprised of Subject Matter 23
8
Experts where updates will be made each year to 1) document progress 1
from the prior year and 2) reassess the risk attributed to each community 2
to determine if the course of replacement should be modified for the 3
upcoming construction year. 4
Q. How much has the gross investment increased since the last rate 5
case? 6
The pro forma 2019 investment is $37.6 million representing an 7
increase of $6.3 million or approximately 20 percent greater than the 8
investment as of 2013. 9
Q. What other adjustments are contributing to the need for an increase 10
in distribution rates? 11
A. In addition to the operating expenses, the Company is requesting 12
the inclusion of the provision for pension and post-retirement benefits, net 13
of the associated deferred taxes, to be added to rate base. 14
Q. Why has the Company proposed to include these assets and 15
liabilities in rate base at this time? 16
A. Recent contributions to the Company’s pension trust fund have 17
resulted in a significant prepaid asset related to the Company’s pension 18
plan as shown in Table 1 below: 19

1
As shown in Table 1, the cash contributions made by the Company 2
have significantly exceeded the pension expense, which is the amount 3
included in the Company’s revenue requirement and recovered through 4
rates charged to customers. Similar to other investments, Montana-5
Dakota has a significant outlay in cash and its only opportunity to earn a 6
return on the outlay of cash is by inclusion in the Company’s rate base. 7
Montana-Dakota has taken a number of steps to minimize pension 8
costs. They include closing the pension plan to new participants as well 9
as freezing the level of benefits accrued. In addition, the Company’s 10
contributions generally result in lower pension expense recovered through 11
the revenue requirement. 12
10
The post retirement prepaid asset, while much smaller in size, has 1
similar characteristics as the prepaid pension asset and was included in 2
the pro forma rate base as well. 3
Q. Have the benefits of the Tax Cuts and Jobs Act of 2017 (TCJA) been 4
reflected in this request for increased revenues? 5
A. Yes. 2018 was the first year of the TCJA and is the test year in this 6
general rate case. As such, the provisions of the TCJA were incorporated 7
in the test year and have been included as pro forma adjustments as 8
explained in detail by Mr. Jacobson. 9
Q. Have you included any provisions related to the TCJA for calendar 10
year 2018? 11
A. Montana-Dakota has accrued a reserve of $80,000 for calendar 12
year 2018. However, the Company's position remains the same as 13
presented in Docket No. 30013-344-GR-18. The rates set in this 14
proceeding will properly reflect the benefits of the TCJA and a separate 15
adjustment is not appropriate for calendar year 2018 as demonstrated by 16
the rate of return of 5.052 percent earned in 2018. As also noted in 17
Docket No. 30013-344-GR-18, Montana-Dakota supports the combination 18
of that docket into this rate case docket to allow both customers and the 19
Commission an opportunity to properly analyze the impact of the TCJA 20
and to provide a reasonable and fair outcome. 21
11
Q. Ms. Kivisto, would you explain how Montana-Dakota strives to 1
efficiently provide safe and reliable service to its Wyoming 2
customers? 3
A. Montana-Dakota works hard to control its costs by continually 4
looking for opportunities that create efficiencies and control costs. In spite 5
of Montana-Dakota’s efforts to control costs, the Company is seeing a 6
need for increased revenue as the need to replace existing infrastructure 7
and add new infrastructure continues. 8
The MDU Utilities Group, which encompasses the four brands I 9
discussed previously, has recently moved forward from a regional 10
operations structure by brand to a functional approach across all brands 11
covering an eight-state service area, striving for operational consistency. 12
The goal is to develop an operations organizational structure to 13
operate as one utility with one vision. 14
• Create efficiencies in operations, technology and support services 15
through common approaches and standards 16
• Gain economics of scale by using resources more effectively 17
• Streamline decision making 18
• Reduce duplication of effort 19
• Better manage the need for additional resources 20
• Implementation of a Pipeline Safety Management System 21
• Ensure the organization is better prepared for growth 22
• Evolution of continuous improvement 23
12
• Build specialized groups with a high level of expertise in their field 1
The functions are organized as follows, each reporting to a Vice 2
President who will oversee the function across all brands and eight states: 3
• Field Operations (Eric Martuscelli - Vice President) 4
Directs and coordinates activities for the entire gas and electric 5
distribution field operations across the eight-state service territory. 6
Oversee the delivery of regulated products and services to our 7
customers. 8
• Operations and Engineering Services (Pat Darras - Vice 9
President) 10
Oversee the development, design and execution of critical and 11
transformative operational strategic initiatives including but not 12
limited to asset management, infrastructure upgrades, and 13
compliance while maintaining engineering and operational 14
excellence across the MDU Utilities Group. 15
• Safety, Process Improvement, and Operations Technology 16
(Hart Gilchrest - Vice President) 17
Oversee the development, design and execution of critical and 18
transformative operational excellence strategic initiatives including 19
but not limited to safety, technical training, safety management 20
systems, process improvement and operations technology. 21
Q. What return is Montana-Dakota requesting in this case? 22
13
A. Montana-Dakota is requesting an overall return of 7.754 percent, 1
inclusive of a return on equity (ROE) of 10.3 percent. Ms. Bulkley’s 2
analysis indicates that a 10.3 percent ROE is fully justified and supported 3
based on the results of her studies. 4
Q. How will the requested increase affect the various classes of 5
customers? 6
A. The proposed percentage change in rates by customer class is as 7
follows: 8
Customer Class Percent
Increase Residential 8.41
Firm General 5.36
Small Interruptible (1.03 ) Large Interruptible (3.06 ) Overall 6.96
Q. Would you please identify the witnesses who will testify on behalf of 9
Montana-Dakota in this proceeding? 10
A. Yes. Following is a list of witnesses that will provide testimony 11
and/or exhibits in support of the Company’s application: 12
• Ms. Tammy J. Nygard, Controller for Montana-Dakota, will testify 13
regarding the overall cost of capital, capital structure and overall 14
debt costs. 15
• Ms. Ann Bulkley, Senior Vice President of Concentric Energy 16
Advisors, Inc. will testify regarding the appropriate cost of common 17
equity for Montana-Dakota’s Wyoming gas operations. 18
14
• Mr. Travis R. Jacobson, Regulatory Analysis Manager for Montana-1
Dakota, will testify regarding the total revenue requirement 2
necessary for Wyoming gas operations. 3
• Mr. Jordan R. Hatzenbuhler, Senior Regulatory Analyst for 4
Montana-Dakota will testify regarding the Company’s embedded 5
class cost of service study and proposed rate design. 6
• Ms. Stephanie Bosch, Regulatory Affairs Manager for Montana-7
Dakota will testify regarding proposed tariff changes as well as 8
volume and revenue analysis. 9
Q. Ms. Kivisto, are the rates requested in this proceeding just and 10
reasonable? 11
A. Yes. In my opinion, the proposed rates are just and reasonable as 12
they are reflective of the total costs being incurred by Montana-Dakota to 13
provide safe and reliable natural gas service to its customers. The 14
proposed rates will provide Montana-Dakota the opportunity to earn a fair 15
and reasonable return on its Wyoming natural gas operations. 16
Q. Does this complete your direct testimony? 17
A. Yes, it does. 18

MONTANA-DAKOTA UTILITIES CO.
Before the Public Service Commission of Wyoming
Docket No. 30013-351-GR-19
Direct Testimony of
Tammy J. Nygard
Q. Please state your name and business address. 1
A. My name is Tammy J. Nygard, and my business address is 400 2
North Fourth Street, Bismarck, North Dakota 58501. 3
Q. By whom are you employed and in what capacity? 4
A. I am the Controller for Montana-Dakota Utilities Co. (Montana-5
Dakota), Cascade Natural Gas Corporation and Intermountain Gas 6
Company, subsidiaries of MDU Resources Group, Inc. as well as Great 7
Plains Natural Gas Co., a division of Montana-Dakota, collectively the 8
MDU Utilities Group. 9
Q. Please describe your duties and responsibilities with Montana-10
Dakota. 11
A. I am responsible for providing leadership and management of the 12
accounting and the financial forecasting/planning functions, including the 13
analysis and reporting of all financial transactions for the MDU Utilities 14
Group. 15
Q. Would you please outline your educational and professional 16
background? 17
2
A. I graduated from the University of Mary with a Bachelor of Science 1
degree in Accounting and Computer Information Systems. I have over 17 2
years of experience in the utility industry. During my tenure with the MDU 3
Utilities Group, I have held positions of increasing responsibility, including 4
Financial Analyst for Montana-Dakota, Director of Accounting and Finance 5
for Cascade, and now as MDU Utilities Group Controller. 6
Q. What is the purpose of your testimony in this proceeding? 7
A. I am responsible for presenting Statement E. 8
Q. Was this statement and the data contained therein prepared by you 9
or under your supervision? 10
A. Yes, it was. 11
Q. Is it true to the best of your knowledge and belief? 12
A. Yes, it is. 13
Q. Would you please explain Statement E? 14
A. Statement E shows the utility capital structure of Montana-Dakota 15
for the twelve months ended December 31, 2018 and the projected capital 16
structure for 2019. Statement E includes the associated costs of debt and 17
common equity. This capital structure and the associated costs serve as 18
the basis for the overall rate of return requested by Montana-Dakota in this 19
rate filing of 7.754 percent. The basis for the requested 10.30 percent 20
return on common equity contained within the overall requested rate of 21
return is supported by the testimony of Ms. Ann Bulkley. 22
3
The components of the 2019 projected overall annual rate of return, 1
which are used by Mr. Jacobson to calculate the revenue requirement, 2
are: 3
Weighted Cost of Capital
Long Term Debt 2.294%
Short Term Debt 0.096% Common Equity 5.364% Required Rate of Return 7.754%
Q. How does the Company finance its natural gas utility operations and 4
determine the amount of common equity and debt to be included in 5
its capital structure? 6
A. As a regulated public utility, the Company has a duty and obligation 7
to provide safe and reliable service to its customers across its service 8
territory while prudently balancing cost and risk. In order to fulfill its 9
service obligations, the Company has made significant capital 10
expenditures for new plant investment throughout its service territory, 11
especially in mains and services. These new investments also have 12
associated operating and maintenance costs. Through its financial 13
planning process, the Company determines the amounts of necessary 14
financing required to support these activities. Montana-Dakota finances its 15
operations with a year-end target of 50 percent common equity. Capital 16
expenditure investments are financed through a mix of internally 17
generated funds, the utilization of the Company’s short-term credit line 18
4
and the issuance of additional debt and common equity financing as 1
required to maintain targeted capital ratios and finance the combined utility 2
operations. 3
The Company obtained $30.0 million of additional common equity 4
in 2018 in order to achieve and maintain the targeted capital structure. 5
The Company redeemed $100.0 million of senior notes upon 6
maturity in September 2018 and issued a thirteen month $100 million 7
London Interbank Offered Rate (LIBOR) floating rate note in September 8
2018 and another in October 2018, for a total of $200 million. This 9
temporary bridge financing was put in place to delay issuance of 10
permanent private placement debt in order to aggregate debt issuances 11
and achieve more attractive long-term pricing and avoid duplication of 12
issuance costs. The Company anticipates a $175 million debt issuance in 13
August 2019. 14
Q. What does Statement E, Schedule E-1 show? 15
A. The debt costs reflected on Statement E, Schedule E-1, page 1 16
represent the actual weighted embedded costs of the long-term debt at 17
December 31, 2018 and those projected to be outstanding at December 18
31, 2019. In calculating the debt costs, the “Yield-to-Maturity” method 19
(also referred to as the Internal Rate of Return (IRR) method) is used to 20
determine the total cost for each respective debt issue, shown on pages 2 21
through 3. The yield-to-maturity calculation of each debt issue outstanding 22
gives consideration to the stated rates of interest being paid on such debt, 23
5
the timing of the interest payments, related issuance expenses, 1
underwriters' commissions, the discount or premium realized upon 2
issuance and the amortization of losses on bond redemption transactions. 3
Q. Would you please describe Statement E, Schedule E-2? 4
A. Schedule E-2 presents the twelve-month average short-term debt 5
balance for 2018 and projected 2019 as well as the average cost of short-6
term debt. A twelve-month average of short-term debt is used in the cost 7
of capital calculation to reflect the seasonality in the short-term debt 8
balance. Short-term debt is historically at or near its peak in December 9
and the twelve-month average calculation is more reflective of the 10
borrowing level than a year-end balance. 11
Q. What does Statement E, Schedule E-3 show? 12
A. The schedule presents the common equity balance at December 13
31, 2018 and the projected balance for December 31, 2019 reflecting the 14
projected activity in the balance. 15
Q. Montana-Dakota's previous capital structure included preferred 16
stock. Has the preferred stock been redeemed? 17
A. Yes, all preferred stock issued and outstanding was redeemed on 18
April 1, 2017. Preferred stock comprised about 0.6 percent of the 2017 19
average capital structure and was replaced with lower cost long-term debt. 20
The redemption reduces the administrative burden associated with the 21
preferred stock and, at the same time, reduces the overall cost of capital. 22
The Company did incur a redemption premium to redeem the preferred 23
6
stock and has deferred the costs of the redemption. As further discussed 1
in the testimony of Mr. Jacobson, Montana-Dakota has included those 2
costs in the rate base similar to debt redemption costs. The inclusion of 3
deferred preferred stock redemption charges in rate base continues to 4
show a net present value benefit to customers. 5
Q. Was it prudent to redeem the preferred stock? 6
A. Yes. By redeeming preferred stock, Montana-Dakota reduced its 7
financing costs. The preferred stock had dividend rates of 4.5% and 4.7%. 8
This was replaced with the fifteen year long-term debt issuance issued in 9
March 2017 at an interest rate of 3.36%. The result of the redemption is a 10
lower overall cost of capital. An analysis has been prepared which 11
demonstrates the overall net benefit of the redemption, inclusive of the 12
rate base impact, is beneficial to customers. 13
Q. Does this conclude your direct testimony? 14
A. Yes, it does. 15

PURPOSE AND OVERVIEW OF DIRECT TESTIMONY 18
Q7. What is the purpose of your Direct Testimony? 19
A7. The purpose of my Direct Testimony is to present evidence and provide a 20
recommendation regarding the appropriate Return on Equity (“ROE”) 1 for the 21
1 Throughout my Direct Testimony, I interchangeably use the terms “ROE” and “cost of equity”.
3
Company’s natural gas utility operations in Wyoming and to provide an assessment 1
of its proposed capital structure to be used for ratemaking purposes. My analyses 2
and recommendations are supported by the data presented in Exhibit No.___(AEB-3
2), Schedules 2 through 14, which were prepared by me or under my direction. 4
Q8. Please provide a brief overview of the analyses that led to your ROE 5
recommendation. 6
A8. As discussed in more detail in Section VI, I applied the Constant Growth form of 7
the Discounted Cash Flow (“DCF”) model, the Capital Asset Pricing Model 8
(“CAPM”), the Risk Premium Approach and the Expected Earnings Analysis. My 9
recommendation also takes into consideration: (1) the Company’s small size; (2) 10
Flotation Cost; (3) the Company’s capital expenditure requirements; (4) the 11
regulatory environment in which the Company operates; and (5) the Company’s 12
adjustment mechanisms. Finally, I considered the Company’s proposed capital 13
structure as compared to the capital structures of the proxy companies.2 While I 14
did not make any specific adjustments to my ROE estimates for any of these factors, 15
I did take them into consideration in aggregate when determining where the 16
Company’s ROE falls within the range of analytical results. 17
Q9. How is the remainder of your Direct Testimony organized? 18
A9. Section II provides a summary of my analyses and conclusions. Section III reviews 19
the regulatory guidelines pertinent to the development of the cost of capital. 20
Section IV discusses current and projected capital market conditions and the effect 21

of those conditions on Montana-Dakota’s cost of equity in Wyoming. Section V 1
explains my selection of a proxy group of natural gas utilities. Section VI describes 2
my analyses and the analytical basis for the recommendation of the appropriate 3
ROE for Montana-Dakota. Section VII provides a discussion of specific regulatory, 4
business, and financial risks that have a direct bearing on the ROE to be authorized 5
for Montana-Dakota in this case. Section VIII assesses the proposed capital 6
structure of Montana-Dakota as compared with the capital structures of the utility 7
operating subsidiaries of the proxy group companies. Section IX presents my 8
conclusions and recommendations for the market cost of equity. 9
SUMMARY OF ANALYSIS AND CONCLUSIONS 10
Q10. Please summarize the key factors considered in your analyses and upon which 11
you base your recommended ROE. 12
A10. My analyses and recommendations considered the following: 13
• The Hope and Bluefield decisions 3 that established the standards for 14
determining a fair and reasonable allowed ROE, including consistency of 15
the allowed return with other businesses having similar risk, adequacy of 16
the return to provide access to capital and support credit quality, and that 17
result must lead to just and reasonable rates. 18
• The effect of current and projected capital market conditions on investors’ 19
return requirements. 20
3 Federal Power Commission v. Hope Natural Gas Co., 320 U.S. 591 (1944); Bluefield Waterworks
& Improvement Co., v. Public Service Commission of West Virginia, 262 U.S. 679 (1923).
5
• The Company’s regulatory, business, and financial risks relative to the 1
proxy group of comparable companies and the implications of those risks 2
in arriving at the appropriate ROE for Montana-Dakota. 3
Q11. Please explain how you considered those factors. 4
A11. I have relied on several analytical approaches to estimate the Company’s cost of 5
equity based on a proxy group of publicly traded companies. As shown in Figure 6
1, those ROE estimation models produce a wide range of results. My conclusion 7
as to where within that range of results Montana-Dakota’s ROE falls is based on 8
the Company’s business and financial risk relative to the proxy group. Although 9
the companies in my proxy group are generally comparable to Montana-Dakota, 10
each company is unique, and no two companies have the exact business and 11
financial risk profiles. Accordingly, we settle on a proxy group with similar, but 12
not the same risk profiles; and adjust the results of our analysis either upwards or 13
downwards within the reasonable range of results to account for any residual 14
differences in risk. 15
Q12. Please summarize the ROE estimation models that you considered to establish 16
the range of ROEs for Montana-Dakota. 17
A12. I considered the results of the Constant Growth DCF model using current dividends, 18
earnings growth rates and stock prices. In addition, I considered two risk premium 19
approaches, the CAPM and a Bond Yield Plus Risk Premium methodology, as well 20
as an Expected Earnings analysis. Figure 1 summarizes the range of results 21
established using each of these estimation methodologies. 22
6
Figure 1: Summary of Cost of Equity Analytical results4 1
2 As shown on Figure 1 (and in Exhibit No.___(AEB-2), Schedule 2), the range of 3
the DCF model results is wide, particularly in relation to the results of the other 4
methodologies. While it is common to consider multiple models to estimate the 5
cost of equity, it is particularly important when the range of results is wide. 6
The requested ROE is for the future rate period; therefore, the analyses supporting 7
my recommendation rely on forward-looking inputs and assumptions (e.g., 8
projected growth rates in the DCF model, forecasted risk-free rate and Market Risk 9
Premium in the CAPM analysis, etc.) and takes into consideration the current high 10
valuations of utility stocks and the market’s expectation for higher interest rates. 11
The use of historical inputs and assumptions would tend to understate the required 12

for individual companies that did not meet the minimum threshold of 7.00 percent.
7
ROE for Montana-Dakota, when considering current and projected conditions in 1
capital markets. 2
As discussed in more detail in Sections IV and VI, the DCF models are influenced 3
by current market conditions that are not projected to be sustained in the long-term. 4
Those conditions result in lower estimates of the ROE using the DCF model. For 5
example, the median low Constant Growth DCF results (prior to exclusions for 6
outliers) for the proxy group, ranging from 7.34 to 7.51 percent for the 30-, 90-, 7
and 180-day assumption, are below an acceptable range of returns for a natural gas 8
utility and are below any authorized ROE for an electric utility or natural gas utility 9
in the U.S. since at least 1980. 5,6 Based on prospective capital market conditions, 10
and the inverse relationship between the market risk premium and interest rates, I 11
conclude that the median low DCF results do not provide a sufficient risk premium 12
to compensate equity investors for the residual risks of ownership, including the 13
risk that they have the lowest claim on the assets and income of Montana-Dakota. 14
Due to these concerns about the results produced by the DCF model, my ROE 15
recommendation considers the median and median-high results of the DCF model, 16
a forward-looking CAPM analysis, a Bond Yield plus Risk Premium analysis, and 17
an Expected Earnings analysis. I also consider company-specific risk factors and 18
current and prospective capital market conditions. 19
5 My DCF models generated a median low, median, and median high result. The median low result
is the median of the proxy group DCF results calculated using the lowest earnings growth rate for each company from Value Line, Yahoo! Finance or Zacks.

Q13. What is your recommended ROE for Montana-Dakota? 1
A13. In addition to the analytical results presented in Figure 1, I also considered the level 2
of regulatory, business, and financial risk faced by Montana-Dakota’s natural gas 3
operations in Wyoming relative to the proxy group to establish the range of 4
reasonable returns. Considering these factors, I believe a range from 10.00 to 10.75 5
percent is reasonable. This recommendation reflects the range of results for the 6
proxy group companies, the relative risk of Montana-Dakota’s natural gas 7
operations in Wyoming as compared to the proxy group, and current capital market 8
conditions. Within that range, a return of 10.30 percent is reasonable. 9
Q14. Please summarize the analysis you conducted in determining that Montana-10
Dakota’s requested capital structure is reasonable and appropriate. 11
A14. Based on the analysis presented in Section VII of my testimony, I conclude that 12
Montana-Dakota’s proposed 52.076 percent common equity is reasonable. To 13
determine if Montana-Dakota’s requested capital structure was reasonable, I 14
reviewed the capital structures of the utility subsidiaries of the proxy companies. 15
As shown in Exhibit No.___(AEB-2), Schedule 13, the results of that analysis 16
demonstrate that the average equity ratios for the utility operating companies of the 17
proxy group range from 47.00 percent to 63.18 percent with an average of 52.94 18
percent. Montana-Dakota’s proposed equity ratio of 52.076 percent is slightly 19
below the average equity ratio for the utility operating subsidiaries of the proxy 20
group companies and is therefore reasonable, especially considering that Federal 21
tax reform legislation has had a negative effect on the cash flows and credit metrics 22
of regulated utilities. 23
9
REGULATORY GUIDELINES 1
Q15. Please describe the guiding principles to be used in establishing the cost of 2
capital for a regulated utility. 3
A15. The United States Supreme Court’s precedent-setting Hope and Bluefield cases 4
established the standards for determining the fairness or reasonableness of a 5
utility’s allowed ROE. Among the standards established by the Court in those cases 6
are: (1) consistency with other businesses having similar or comparable risks; (2) 7
adequacy of the return to support credit quality and access to capital; and (3) that 8
the result, as opposed to the methodology employed, is the controlling factor in 9
arriving at just and reasonable rates.7 10
Q16. Has the Commission provided similar guidance in establishing the appropriate 11
return on common equity? 12
A16. Yes, it has. In Docket No. 20000-ER-03-198, PacifiCorp’s 2003 rate case, the 13
Commission stated that: 14
Consistent with the discretion given to the Commission in 15 examining cases and reaching a just result (discussed 16 generally, infra), there are no precise bases in Wyoming law 17 to guide the Commission in determining a utility’s rate of 18 return on equity. Therefore, the Commission must apply its 19 informed judgment to all of the evidence in the case. In this 20 traditional rate-base rate-of-return case, the Commission must 21 determine the cost of capital, and we are guided by the 22 earnings and capital attraction standards of Bluefield Water 23 Works & Improvement Co. v. Public Service Commission of 24 West Virginia, 262 U. S. 679 (1923); and Federal Power 25 Comm’n v. Hope Natural Gas Co., 320 U. S. 391 (1944); 26 accepted in Wyoming in In re Northern Utilities, 70 Wyo. 275, 27 249 P.2d 769 (Wyo. 1952). A public utility remains entitled to 28

10
rates which will permit it a reasonable opportunity to earn a 1 return on its investment properly reflecting the risk of the 2 business and which will reasonably preserve the financial 3 soundness of the company and allow it to raise the capital 4 needed to provide service in the public interest. Having said 5 that, we also acknowledge that the measurement of the 6 required level of return is not a matter of simple mathematics 7 but is a matter requiring judgment and the employment of 8 discretion. The United States Supreme Court, in Hope, supra, 9 noted that a “just and reasonable end result” is the desired 10 outcome and that it is the end reached, rather than the method 11 employed in achieving it, that should control.8 12
My view accords with this guidance that an allowed ROR must be sufficient to 13
enable regulated companies, like Montana-Dakota, the ability to attract capital on 14
reasonable terms. 15
Q17. Why is it important for a utility to be allowed the opportunity to earn an ROE 16
that is adequate to attract capital at reasonable terms? 17
A17. An ROE that is adequate to attract capital at reasonable terms enables the Company 18
to continue to provide safe, reliable natural gas service while maintaining its 19
financial integrity. To the extent the Company is provided the opportunity to earn 20
its market-based cost of capital, neither customers nor shareholders are 21
disadvantaged. 22
Q18. Is a utility’s ability to attract capital also affected by the ROEs that are 23
authorized for other utilities? 24
A18. Yes. Utilities compete directly for capital with other investments of similar risk, 25
which include other natural gas and electric utilities. Therefore, the ROE awarded 26
to a utility sends an important signal to investors regarding whether there is 27
8 PacifiCorp, Docket No. 20000-ER-03-198, Order, February 28, 2004, at ¶ 34 a13.
11
regulatory support for financial integrity, dividends, growth, and fair compensation 1
for business and financial risk. The cost of capital represents an opportunity cost 2
to investors. If higher returns are available for other investments of comparable 3
risk, investors have an incentive to direct their capital to those investments. Thus, 4
an authorized ROE significantly below authorized ROEs for other natural gas and 5
electric utilities can inhibit the utility’s ability to attract capital for investment in 6
Wyoming. 7
While Montana-Dakota is committed to investing the required capital to provide 8
safe and reliable service, because Montana-Dakota is a subsidiary of MDU 9
Resources, Montana-Dakota competes with the other MDU Resources subsidiaries 10
for discretionary investment capital. In determining how to allocate its finite 11
discretionary capital resources, it would be reasonable for MDU Resources to 12
consider the authorized ROE of each of its subsidiaries. 13
Q19. What are your conclusions regarding regulatory guidelines? 14
A19. The ratemaking process is premised on the principle that, for investors and 15
companies to commit the capital needed to provide safe and reliable utility services, 16
a utility must have the opportunity to recover the return of, and the market-required 17
return on, its invested capital. Because utility operations are capital-intensive, 18
regulatory decisions should enable the utility to attract capital at reasonable terms 19
under a variety of economic and financial market conditions; doing so balances the 20
long-term interests of the utility and its ratepayers. 21
12
The financial community carefully monitors the current and expected financial 1
condition of utility companies, and the regulatory framework in which they operate. 2
In that respect, the regulatory framework is one of the most important factors in 3
both debt and equity investors’ assessments of risk. The Commission’s order in 4
this proceeding, therefore, should establish rates that provide the Company with the 5
opportunity to earn an ROE that is: (1) adequate to attract capital at reasonable 6
terms under a variety of economic and financial market conditions; (2) sufficient to 7
ensure good financial management and firm integrity; and (3) commensurate with 8
returns on investments in enterprises with similar risk. To the extent Montana-9
Dakota is authorized the opportunity to earn its market-based cost of capital, the 10
proper balance is achieved between customers’ and shareholders’ interests. 11
CAPITAL MARKET CONDITIONS 12
Q20. Why is it important to analyze capital market conditions? 13
A20. The ROE estimation models rely on market data that are either specific to the proxy 14
group, in the case of the DCF model, or to the expectations of market risk, in the 15
case of the CAPM. The results of the ROE estimation models can be affected by 16
prevailing market conditions at the time the analysis is performed. While the ROE 17
that is established in a rate proceeding is intended to be forward-looking, the analyst 18
uses current and projected market data, specifically stock prices, dividends, growth 19
rates and interest rates in the ROE estimation models to estimate the required return 20
for the subject company. 21
13
As discussed in the remainder of this section, analysts and regulatory commissions 1
have concluded that current market conditions have affected the results of the ROE 2
estimation models. As a result, it is important to consider the effect of these 3
conditions on the ROE estimation models when determining the appropriate range 4
and recommended ROE for a future period. If investors do not expect current 5
market conditions to be sustained in the future, it is possible that the ROE 6
estimation models will not provide an accurate estimate of investors’ required 7
return during that rate period. Therefore, it is very important to consider projected 8
market data to estimate the return for that forward-looking period. 9
Q21. What factors are affecting the cost of equity for regulated utilities in the 10
current and prospective capital markets? 11
A21. The cost of equity for regulated utility companies is being affected by several 12
factors in the current and prospective capital markets, including: (1) the current low 13
interest rate environment and the corresponding effect on valuations and dividend 14
yields of utility stocks relative to historical levels; (2) the market’s expectation for 15
interest rates; and (3) recent Federal tax reform. In this section, I discuss each of 16
these factors and how it affects the models used to estimate the cost of equity for 17
regulated utilities. 18
A. The Effect of Market Conditions on Valuations 19
Q22. How has the Federal Reserve’s monetary policy affected capital markets in 20
recent years? 21
A22. Extraordinary and persistent federal intervention in capital markets artificially 22
lowered government bond yields after the Great Recession of 2008-2009, as the 23
14
Federal Open Market Committee (“FOMC”) used monetary policy (both reductions 1
in short-term interest rates and purchases of Treasury bonds and mortgage-backed 2
securities) to stimulate the U.S. economy. As a result of very low or zero returns 3
on short-term government bonds, yield-seeking investors have been forced into 4
longer-term instruments, bidding up prices and reducing yields on those 5
investments. As investors have moved along the risk spectrum in search of yields 6
that meet their return requirements, there has been increased demand for dividend-7
paying equities, such as natural gas and electric utility stocks. 8
Q23. How has the period of abnormally low interest rates affected the valuations 9
and dividend yields of utility shares? 10
A23. The Federal Reserve’s accommodative monetary policy has caused investors to 11
seek alternatives to the historically low interest rates available on Treasury bonds. 12
A result of this search for higher yield is that the share prices for many common 13
stocks, especially dividend-paying stocks such as utilities, have been driven higher 14
while the dividend yields (which are computed by dividing the dividend payment 15
by the stock price) have decreased to levels well below the historical average. As 16
shown in Figure 2, over the period from 2009 through 2017, since the Federal 17
Reserve intervened to stabilize financial markets and support the economic 18
recovery after the Great Recession of 2008-09, Treasury bond yields and utility 19
dividend yields declined. Specifically, Treasury bond yields declined by 20
approximately 118 basis points, and natural gas utility dividend yields have 21
decreased by about 144 basis points over this same period. 22
15

Q24. How have higher stock valuations and lower dividend yields for utility 5
companies affected the results of the DCF model? 6
A24. During periods of general economic and capital market stability, the DCF model 7
may adequately reflect market conditions and investor expectations. However, in 8
the current market environment, the DCF model results are distorted by the 9
historically low level of interest rates and the higher valuation of utility stocks. 10
Value Line recently commented on the high valuations of electric utilities: 11
Even after a pullback in late 2018, most stocks in the Electric 12 Utility Industry are still priced expensively, in our view. Many 13 of the equities are still trading within our 2021-2023 Target 14 Price Range. The industry’s average dividend yield is 3.5%, 15 and some stocks have yields that aren’t significantly higher 16 than the median of all stocks under our coverage. For the 3- to 17

5-year period, the group’s average total return potential is just 1 5%.9 2
This is further supported by a recent Edward Jones report on the utility sector: 3
Utility valuations have climbed back to near-record levels as 4 10-year Treasury bond rates have fallen back to around 2.5%. 5 On a price-to-earnings basis, remain significantly above their 6 historical average, and have been trading near all-time highs. 7 We have seen utility valuations moving in line with interest 8 rate movements, although there have been exceptions to this. 9 Overall, however, we believe the low-interest rate 10 environment has been the biggest factor in pushing utilities 11 higher since many investors buy them for their dividend yield. 12
Utilities recently hit new all-time highs, and are still trading 13 significantly above their average price-to-earnings ratio over 14 the past decade. The premium valuation continues to reflect 15 not only the low interest rate environment, but also the stable 16 and predominantly regulated earnings growth we foresee.10 17
As noted by Value Line and Edward Jones, over the last few years, utility stocks 18
have experienced high valuations and low dividend yields; driven by investors 19
moving into dividend paying stocks from bonds due to the low interest rates in the 20
bond market, however, those dynamics are changing. Value Line and Edward 21
Jones recognize that as interest rates increase, bonds become a substitute for utility 22
stocks. As utility stock prices decline, the dividend yields will increase. This 23
change in market conditions implies that the ROE calculated using historical market 24
data in the DCF model may understate the forward-looking cost of equity. 25

Q25. How did the Standard & Poor’s (“S&P”) Utilities Index respond to the market 1
conditions that existed following the Great Recession of 2008-2009? 2
A25. Figure 3, demonstrates market conditions from 2007-2019 as measured by the S&P 3
Utilities index and the yield on 30-year Treasury bonds. As shown in Figure 3, the 4
S&P Utilities index increased steadily from the beginning of 2009 through early 5
November 2017, as yields on 30-year Treasury bonds declined in response to 6
accommodative federal monetary policy. 7

Q26. How do the valuations of public utilities compare to the historical average? 11
A26. Figure 4 summarizes the average historical and projected P/E ratios for the proxy 12
companies calculated using data from Bloomberg Professional and Value Line.11 13
As shown in Figure 4, the average P/E ratio for the proxy companies was higher in 14

18
2017 than at any other time in the last seventeen years and is significantly higher 1
than the average projected P/E ratio for the group for the period from 2022-2024. 2
In 2018 however, the average P/E ratio for the proxy companies has decreased to 3
19.66 from the high in 2017 of 24.63. All else equal, if P/E ratios for the proxy 4
companies continue to decline, as Value Line projects, the ROE results from the 5
DCF model would be higher. Therefore, the DCF model using historical market 6
data is likely understating the forward-looking cost of equity for the proxy group 7
companies. 8

Q27. Have you reviewed any other market indicators that compare the current 1
valuation of utilities to the historical average? 2
A27. Yes. To further assess how the current low interest rate environment has affected 3
the valuations of the companies in my proxy group, I reviewed the price/earnings 4
to growth (“PEG”) ratio for the S&P Utilities Index. The PEG ratio is commonly 5
used by investors to determine if a company is considered over- or under-valued. 6
The ratio compares the P/E ratio of a company to the expected growth rate of future 7
earnings. This allow investors to compare companies with similar P/E ratios but 8
different earnings growth projections. If two companies have a P/E ratio of 20, but 9
Company A is growing at a rate of 6 percent and Company B is growing at a rate 10
of 15 percent, then on a relative valuation basis Company B is the better investment. 11
As shown on page 7 of Exhibit __(AEB-2), Schedule 14, which is a report 12
published by Yardeni Research, Inc., the PEG ratio for the S&P Utilities Index has 13
been significantly higher than it has historically as a result of the accommodative 14
monetary policy pursued by the Federal Reserve following the Great Recession of 15
2008/09. 12 While the PEG ratio has declined in recent years due to the Federal’s 16
Reserve’s shift to normalize monetary policy, the PEG ratio for the S&P Utilities 17
Index is still above the historical average. In general, stocks with lower long-term 18
PEG ratios are considered better values. As the PEG ratio increases above the long-19
term historical average, as has been the case with the S&P Utilities Index, then the 20
stocks are considered relatively over-valued unless the growth rate increases to 21
12 Yardeni Research, Inc. “S&P 500 Industry Briefing: Utilities.” April 30, 2019,

20
support the higher valuation. The PEG ratio for the S&P Utilities Index as of April 1
2019 is close to 3.5, which indicates that many of the stocks contained in the index 2
are currently trading at levels well above the historical average. Based on this 3
valuation metric, investors should expect the stock prices of utilities to decline in 4
the future. This analysis supports the P/E Ratio projections produced by Value 5
Line, which as noted above, are projecting the P/E ratios of utilities to decline over 6
the near-term. 7
Q28. How do equity investors view the utilities sector based on these recent market 8
conditions? 9
A28. Investment advisors have suggested that utility stocks may underperform as a result 10
of market conditions. Barron’s recently published the results of its survey of 148 11
profession money manager in which 64 percent of the professional money 12
managers surveyed recommended selling utility stocks.13 This position was further 13
supported in a separate article where Barron’s noted that: 14
Utilities, by contrast, have returned about 19% in the past year. 15 Investors view them as a safer bet and more-reliable dividend 16 plays. Higher share prices have pushed down their yields, 17 which have averaged about 3.8% over the past 10 years, 18 according to FactSet. 19
Nancy Tengler, chief investment strategist at Tengler Wealth 20 Management, is avoiding utility stocks, which in her view 21 offer "high multiples for no growth."14 22

Similarly, a recent report on the market outlook for 2019 from J.P. Morgan Asset 1
Management noted that due to higher volatility the Fed may pause increasing the 2
federal funds rate; however, they are not recommending rotation into the utility 3
sector: 4
As prospects for slower economic growth become clearer in 5 the middle of next year, the Fed may signal it will pause. Such 6 a signal, or a trade agreement with China, could lead multiples 7 to expand, pushing the stock market higher and potentially 8 adding years to this already old bull market. However, even if 9 the bull market does end in the next few years, it is important 10 to remember that late-cycle returns have typically been quite 11 strong. 12
This leaves investors in a tough spot – should they focus on a 13 fundamental story that is softening, or invest with an 14 expectation that multiples will expand as the bull market runs 15 its course? The best answer is probably a little bit of each. We 16 are comfortable holding stocks as long as earnings growth is 17 positive, but do not want to be over-exposed given an 18 expectation for higher volatility. As such, higher-income 19 sectors like financials and energy look more attractive than 20 technology and consumer discretionary, and we would lump 21 the new communication services sector in with the latter 22 names, rather than the former. However, given our 23 expectation of still some further interest rate increases, it does 24 not yet seem appropriate to fully rotate into defensive sectors 25 like utilities and consumer staples. Rather, a focus on cyclical 26 value should allow investors to optimize their 27 upside/downside capture as this bull market continues to 28 age.15 29
This view was further supported by UBS who underweights utilities: 30
Our underweight views on consumer staples and utilities 31 sectors reflect our preference for sectors that are more 32 leveraged to continued favorable economic growth than these 33 two defensive sectors. In addition, consumer staples are 34
15 J.P. Morgan Asset Management, “The investment outlook for 2019: Late-cycle risks and
opportunities”, November 30, 2018, at 5.
22
contending with sluggish organic growth. High dividend 1 yields for the utilities sector makes it most negatively exposed 2 to higher interest rates. Our industrials underweight is a bit of 3 a hedge against a potential increase in trade frictions.16 4
Q29. Have regulators recently responded to the historically low dividend yields for 5
utility companies and the corresponding effect on the DCF model? 6
A29. Yes. The FERC recently proposed a methodology that reflects their current view 7
that investors rely on multiple ROE estimation models. The proposed methodology 8
includes an equal weighting of the DCF, CAPM, Expected Earnings and Risk 9
Premium models to better reflect investor behavior and capital market conditions.17 10
In addition, the Illinois Commerce Commission (“ICC”), the Pennsylvania Public 11
Utility Commission (“PPUC”) and the Missouri Public Service Commission 12
(“Missouri PSC”) have all considered the effect of low dividend yields on the DCF 13
results in recent decisions. I discuss the response of these regulators to historically 14
low dividend yields and the impact on the DCF model in detail later in my 15
testimony. 16
B. The Current and Expected Interest Rate Environment 17
Q30. Please provide a brief summary of the recent monetary policy actions of the 18
Federal Reserve. 19
A30. Based on stronger conditions in employment markets, a relatively stable inflation 20
rate, steady economic growth, and increased household spending, the Federal 21
Reserve raised the short-term borrowing rate by 25 basis points on four occasions 22
16 UBS, “2019 outlook: Aging gracefully”, December 5, 2018, at 7. 17 Federal Energy Regulatory Commission, Docket No. EL 11-66-001, et al., Order Directing Briefs,
issued October 16, 2018, at para. 32.
23
in 2018. Since December 2015, the Federal Reserve has increased interest rates 1
nine times, bringing the federal funds rate to the range of 2.25 percent to 2.50 2
percent. While, the Federal Reserve recently indicated at the March 2019 meeting 3
that going forward it will be patient in determining future adjustments to the federal 4
funds rate due to recent global economic and financial developments and low 5
inflationary pressures, the FOMC has not indicated that they will not raise interest 6
rates over the coming year. In fact, Bloomberg recently noted that some officials 7
saw higher rates as appropriate later this year if economic growth continued above 8
its longer-run trend rate, according to the minutes. 18 This view was further 9
supported following the May 2019 meeting by Federal Reserve Bank of 10
Philadelphia President Patrick Harker who indicated that he still expects the Federal 11
Reserve to increase rates once in both 2019 and 2020.19 12
Additionally, in October 2017, the FOMC started reducing the size of the Federal 13
Reserve’s $4.5 trillion bond portfolio by no longer reinvesting the proceeds of the 14
bonds it holds. In response to the Great Recession, the Federal Reserve pursued a 15
policy known as “Quantitative Easing,” in which it systematically purchased 16
mortgage-backed securities and long-term Treasury bonds to provide liquidity in 17
financial markets and drive down yields on long-term government bonds. Although 18
the Federal Reserve discontinued the Quantitative Easing program in October 2014, 19

it continued to reinvest the proceeds from the bonds it holds. Under the initial 1
balance sheet normalization policy, the FOMC gradually reduced the Federal 2
Reserve’s securities holdings by $10 billion per month initially, ramping up to $50 3
billion per month by the end of the first twelve months.20 However, at the March 4
2019 meeting, the FOMC announced that it intends to slow the reduction of its 5
holdings of Treasury Securities starting in May 2019 and ultimately conclude the 6
program in September 2019.21 7
Q31. How does the recent change in the Federal Reserve’s policy affect the yields 8
on long-term government bonds? 9
A31. While the Federal Reserve has recently indicated to that will it will be patient in 10
determining future adjustments the federal funds rate, this is not unusual as 11
monetary policy has a lagged effect on the economy. As Federal Reserve Bank of 12
San Francisco notes: 13
It can take a fairly long time for a monetary policy action to 14 affect the economy and inflation. And the lags can vary a lot, 15 too. For example, the major effects on output can take 16 anywhere from three months to two years. And the effects on 17 inflation tend to involve even longer lags, perhaps one to three 18 years, or more.22 19
Since December 2015, the Federal Reserves has increased the federal funds rate 20
nine times, four of which occurred in 2018 and three in 2017. Therefore, given 21
20 Federal Reserve press release, Addendum to the Policy Normalization Principles and Plans, June
14, 2017, implemented at FOMC meeting, September 20, 2017. 21 Federal Reserve press release, Balance Sheet Normalization Principles and Plans, March 20, 2019. 22 Federal Reserve Bank of San Francisco, "U.S. Monetary Policy: An Introduction - How does
monetary policy affect the U.S. economy?", February 6, 2004. https://www.frbsf.org/education/teacher-resources/us-monetary-policy-introduction/real-interest-rates-economy/
25
recent market volatility and lagged effect that monetary policy has on the economy, 1
it is reasonable to expect the Federal Reserve to be patient with future increases. 2
However, it is important to note, that the Federal Reserve is continuing to reduce 3
the size of its balance sheet by no longer reinvesting the proceeds of the bonds it 4
holds over the near-term. This policy in conjunction with the lagged effect of past 5
increases in the federal funds rate suggests that the yields on long-term government 6
bonds should continue to increase over the near-term which is consistent with 7
investors’ expectations. 8
Q32. Have you examined the effect of the Federal Reserve’s monetary policy on the 9
yields of long-term government bonds over the past few years? 10
A32. Yes. The increase in long-term government bond yields has not been as 11
pronounced as the rise in short-term interest rates. This is due to a shift in the supply 12
and demand of long-term government bonds that has occurred since 2009. For 13
example, since the Great Recession of 2008-2009, federal debt has increased 14
significantly which has resulted in an increase in the supply of Treasury bonds in 15
the market. In general, an increase in supply should result in a decrease in the price 16
of Treasury bonds and an increase in yield. However, long-term government bonds 17
yields have not increased as fast as expected given the increase in supply. This is 18
because the demand for Treasury bonds has also increased since 2009. As noted in 19
a recent article published by the St. Louis Federal Reserve, the demand for 20
government bonds increased for a number of reasons some of which included 21
increased holdings by foreign governments as countries in Europe and Asia faced 22
their own economic uncertainty, and increased holdings from commercial banks 23
26
due to new regulations that required banks to hold a larger portion of high-quality 1
liquid assets.23 This has resulted in a more gradual increase in the yields on long-2
term government bonds over the past few years. 3
Q33. Is the demand for long-term government bonds currently increasing? 4
A33. No, it is not. As noted in the Federal Reserve article: 5
Some evidence suggests that the growth in demand for 6 Treasuries has already begun to soften. Returning to Figures 7 1 and 2, foreign holdings have remained more or less constant 8 since 2014, largely because of declining holdings in Japan and 9 China. Likewise, regulation and policy changes such as the 10 Dodd-Frank Act and new rules for prime money market funds 11 may have only transitory effects on the demand for Treasuries. 12 For example, the pace of growth of the ratio of commercial 13 bank Treasury security holdings to private loans has slowed 14 since 2014 (see Figure 3), as has the growth of investment in 15 government money market funds since 2017 (Figure 4).24 16
Furthermore, another indicator of the demand for Treasury bonds is the bid-to-17
cover ratio, which represents the dollar amount of bids received versus the dollar 18
amount sold in a Treasury security auction. Therefore, a higher bid-to-cover ratio 19
is indicative of an increase in the demand for government bonds. As shown in 20
Figure 5, the bid-to-cover ratio for the 10-year U.S. Treasury bond is currently at 21
its lowest point since 2009, which indicates that the demand for long-term 22
government bonds has declined. The decline in demand is occurring at a time when 23
the supply of Treasury bonds is expected to increase as the Federal Reserve 24
continues its balance sheet unwind over the near-term and the federal government 25

issues bonds to offset the reduced tax revenue associated with the implementation 1
of the TCJA. As a result, yields on long-term government bonds are expected to 2
continue to increase over the near-term. 3

5 Q34. What effect do rising interest rates have on the cost of equity? 6
A34. As interest rates increase, the cost of equity for the proxy companies using the DCF 7
model is likely to be an overly conservative estimate of investors’ required returns 8
because the proxy group average dividend yield reflects the increase in stock prices 9
that resulted from substantially lower interest rates. As such, rising interest rates 10
support the selection of a return toward the upper end of a reasonable range of ROE 11
estimates resulting from the DCF analysis. Alternatively, my CAPM and Bond 12
Yield Plus Risk Premium analyses include estimated returns based on near-term 13
projected interest rates, reflecting investors’ expectations of market conditions over 14
the period that the rates that are determined in this case will be set. 15
28
C. Effect of Tax Reform on the ROE and Capital Structure 1
Q35. Are there other factors that should be considered in determining the cost of 2
equity for Montana-Dakota? 3
A35. Yes. The effect of the TCJA should also be considered in the determination of the 4
cost of equity. The credit rating agencies have commented on the effect of the 5
TCJA on regulated utilities. In summary, the TCJA is expected to reduce utility 6
revenues due to the lower federal income taxes and the requirement to return excess 7
accumulated deferred income taxes. This change in revenue is expected to reduce 8
Funds From Operations (“FFO”) metrics across the sector, and absent regulatory 9
mitigation strategies, is expected to lead to weaker credit metrics and negative 10
ratings actions for some utilities.25 11
Q36. Have credit or equity analysts commented on the effect of the TCJA on 12
utilities? 13
A36. Yes. Moody’s Investors Services (“Moody’s”) indicated that while the TCJA was 14
credit positive for many sectors, it has an overall negative credit impact on 15
regulated operating companies of utilities and their holding companies due to the 16
reduction in cash flow metrics that results from the change in the federal tax rate 17
and the loss of bonus depreciation. 18
Moody’s noted that the rates that regulators allow utilities to charge customers is 19
based on a cost-plus model, with tax expense being one of the pass-through items. 20
Utilities will collect less taxes at the lower rate, reducing revenue. While the taxes 21
25 FitchRatings, Special Report, What Investors Want to Know, “Tax Reform Impact on the U.S.
Utilities, Power & Gas Sector”, January 24, 2018.
29
are ultimately paid out as an expense, under the new law utilities lose the timing 1
benefit, reducing cash that may have been carried over a number of years. The 2
lower tax rate combined with the loss of bonus depreciation will have a negative 3
effect on utility cash flows and will ultimately negatively impact the utilities’ ability 4
to fund ongoing operations and capital improvement programs. 5
Q37. How has Moody’s responded to the increased risk for utilities resulting from 6
the TCJA? 7
A37. In January 2018, Moody’s issued a report changing the rating outlook for several 8
regulated utilities from Stable to Negative.26 At that time, Moody’s noted that the 9
rating change affected companies with limited cushion in their ratings for 10
deterioration in financial performance. In June 2018, Moody’s issued a report in 11
which the rating agency downgraded the outlook for the entire regulated utility 12
industry from Stable to Negative for the first time ever. Moody’s cites ongoing 13
concerns about the negative effect of the TCJA on cash flows of regulated utilities. 14
While noting that “[r]egulatory commissions and utility management teams are 15
taking important first steps” 27 and that “we have seen some credit positive 16
developments in some states in response to tax reform,”28 Moody’s concludes that 17
“we believe that it will take longer than 12-18 months for the majority of the sector 18
to show any material financial improvement from such efforts.”29 19
26 Moody’s Investor Service, Global Credit Research, Rating Action: Moody’s changes outlooks on
25 US regulated utilities primarily impacted by tax reform, January 19, 2018. 27 Moody’s Investors Service, “Regulated utilities – US: 2019 outlook shifts to negative due to weaker
cash flows, continued high leverage”, June 18, 2018, at 3. 28 Ibid. 29 Ibid.
30
Q38. Has Moody’s changed its outlook for utilities in 2019? 1
A38. No. Consistent with the prior reports issued by Moody’s in January and June of 2
2018, Moody’s is maintaining its negative outlook for regulated utilities in 2019 as 3
a result of continued concerns over the effect of the TCJA on cash flows as well as 4
increasing debt.30 Moody’s notes that “[t]he combination of financial pressures is 5
expected to keep the sector’s ratio of FFO to debt down around 15% in the year 6
ahead.” 31 7
Q39. What does it mean for Moody’s to downgrade a credit outlook? 8
A39. A Moody’s rating outlook is an opinion regarding the likely rating direction over 9
what it refers to as “the medium term.” A Stable outlook indicates a low likelihood 10
of a rating change in the medium term. A Negative outlook indicates a higher 11
likelihood of a rating change over the medium term. While Moody’s indicates that 12
the time period for changing a rating subsequent to a change in the outlook from 13
Stable will vary, on average Moody’s indicates that a rating change will follow 14
within a year of a change in outlook.32 15
Q40. Have any utilities experienced a downgrade related to cash flow metrics 16
resulting from the TCJA? 17
A40. Yes. Figure 6 summarizes credit rating downgrades for utilities that have resulted 18
from tax reform. 19

outlook for 2019 remains negative, November 8, 2018. 31 Ibid. 32 Moody’s Investors Service, Rating Symbols and Definitions, July 2017, at 27.

2 Q41. Have other rating agencies commented on the effect of the TCJA on ratings? 3
A41. Yes. S&P and Fitch have also commented on the implications of the TCJA on 4
utilities. S&P published a report on January 24, 2018, entitled “U.S. Tax Reform: 5
For Utilities’ Credit Quality, Challenges Abound” in which S&P concludes: 6
The impact of tax reform on utilities is likely to be negative to 7 varying degrees depending on a company’s tax position going 8 into 2018, how its regulators react, and how the company 9 reacts in return. It is negative for credit quality because the 10 combination of a lower tax rate and the loss of stimulus 11 provisions related to bonus depreciation or full expensing of 12 capital spending will create headwinds in operating cash-flow 13 generation capabilities as customer rates are lowered in 14 response to the new tax code. The impact could be sharpened 15 or softened by regulators depending on how much they want 16 to lower utility rates immediately instead of using some of the 17 lower revenue requirement from tax reform to allow the utility 18 to retain the cash for infrastructure investment or other 19
32
expenses. Regulators must also recognize that tax reform is a 1 strain on utility credit quality, and we expect companies to 2 request stronger capital structures and other means to offset 3 some of the negative impact. 4
Finally, if the regulatory response does not adequately 5 compensate for the lower cash flows, we will look to the 6 issuers, especially at the holding company level, to take steps 7 to protect credit metrics if necessary. Some deterioration in 8 the ability to deduct interest expense could occur at the parent, 9 making debt there relatively more expensive. More equity 10 may make sense and be necessary to protect ratings if financial 11 metrics are already under pressure and regulators are 12 aggressive in lowering customer rates. It will probably take 13 the remainder of this year to fully assess the financial impact 14 on each issuer from the change in tax liabilities, the regulatory 15 response, and the company's ultimate response. We have 16 already witnessed differing responses. We revised our outlook 17 to negative on PNM Resources Inc. and its subsidiaries on Jan. 18 16 after a Public Service Co. of New Mexico rate case decision 19 incorporated tax savings with no offsetting measures taken to 20 alleviate the weaker cash flows. It remains to be seen whether 21 PNM will eventually do so, especially as it is facing other 22 regulatory headwinds. On the other hand, FirstEnergy Corp. 23 issued $1.62 billion of mandatory convertible stock and $850 24 million of common equity on Jan. 22 and explicitly referenced 25 the need to support its credit metrics in the face of the new tax 26 code in announcing the move. That is exactly the kind of 27 proactive financial management that we will be looking for to 28 fortify credit quality and promote ratings stability.33 29
In S&P’s 2019 trends report, the rating agency notes that the utility industry’s 30
financial measures weakened in 2018 and attributed that to tax reform, capital 31
spending and negative load growth. In addition, S&P expects that weaker credit 32
metrics will continue into 2019 for those utilities operating with minimal financial 33
cushion. S&P further expects that these utilities will look to offset the revenue 34
reductions from tax reform with equity issuances. The rating agency reported that 35
33 Standard and Poor’s Global Ratings, “U.S. Tax Reform: For Utilities’ Credit Quality, Challenges
Abound”, January 24, 2018.
33
in 2018 regulated utilities issued nearly $35 billion in equity, which is more than 1
twice the equity issuances in 2016 and 2017.34 2
Finally, FitchRatings recognized the implications of tax reform but indicated that 3
any ratings actions will be guided by the response of regulators and the management 4
of the utilities. Fitch notes that the solution will depend on the ability of utility 5
management to manage the cash flow implications of the TCJA. Fitch offers 6
several solutions to provide rate stability and to moderate changes to cash flow in 7
the near term, including increasing the authorized ROE and/or equity ratio.35 8
Q42. What conclusions do you draw from your analysis of capital market 9
conditions? 10
A42. The important conclusions resulting from capital market conditions are: 11
• The assumptions used in the ROE estimation models have been affected by 12
recent historical market conditions. 13
• Recent market conditions are not expected to persist as yields on long-term 14
bonds are expected to increase. As a result, the recent historical market 15
conditions are not reflective of the market conditions that will be present 16
when the rates for Montana-Dakota will be in effect. 17
• It is important to consider the results of a variety of ROE estimation models, 18
using forward-looking assumptions to estimate the cost of equity. 19
34 Standard & Poor’s Ratings, “Industry Top Trends 2019, North America Regulated Utilities”,
November 8, 2019. 35 FitchRatings, Special Report, What Investors Want to Know, “Tax Reform Impact on the U.S.
Utilities, Power & Gas Sector”, January 24, 2018.
34
• Without adequate regulatory support, the TCJA will have a negative effect 1
on utility cash flows, which increases investor risk expectations for utilities. 2
PROXY GROUP SELECTION 3
Q43. Why have you used a group of proxy companies to estimate the cost of equity 4
for Montana-Dakota? 5
A43. In this proceeding, we are focused on estimating the cost of equity for a natural gas 6
utility company that is not itself publicly traded. Because the cost of equity is a 7
market-based concept and given that Montana-Dakota’s natural gas operations in 8
Wyoming do not make up the entirety of a publicly traded entity, it is necessary to 9
establish a group of companies that is both publicly traded and comparable to 10
Montana-Dakota in certain fundamental business and financial respects to serve as 11
its “proxy” in the ROE estimation process. 12
Even if Montana-Dakota was a publicly-traded entity, it is possible that transitory 13
events could bias its market value over a given period. A significant benefit of 14
using a proxy group is that it moderates the effects of unusual events that may be 15
associated with any one company. The proxy companies used in my analyses all 16
possess a set of operating and risk characteristics that are substantially comparable 17
to the Company, and thus provide a reasonable basis to derive and estimate the 18
appropriate ROE for Montana-Dakota. 19
Q44. Please provide a brief profile of Montana-Dakota. 20
A44. Montana-Dakota is a natural gas distribution company that is a wholly-owned 21
subsidiary of MDU Resources. The Company operates in Montana, North Dakota, 22
South Dakota and Wyoming. In Wyoming, the Company distributes natural gas to 23
35
approximately 19,000 residential, commercial and industrial customers in 9 1
communities.36 As of December 31, 2018, Montana-Dakota’s net utility natural 2
gas plant in Wyoming was approximately $16.89 million.37 In addition, Montana-3
Dakota had total natural gas sales in Wyoming in 2018 of approximately 5.56 4
million Dths, made up of 28.67 percent residential, 19.56 percent commercial, 0.29 5
percent industrial, 0.05 percent interdepartmental and 51.43 percent 6
transportation. 38 For Montana-Dakota’s parent company, MDU Resources, 7
Wyoming accounted for 2.00 percent of the natural gas distribution operating sales 8
revenues in 2018, while Idaho (30.00 percent), Washington (26.00 percent), North 9
Dakota (15.00 percent), Montana (9.00 percent), Oregon (8.00 percent), South 10
Dakota (7.00 percent), and Minnesota (3.00 percent) accounted for the other 98.00 11
percent of retail gas distribution operating sales revenues. 39 Montana-Dakota 12
currently has an investment grade long-term rating of A- (Outlook: Stable) from 13
S&P and A- (Outlook: Stable) from Fitch.40 14
Q45. How did you select the companies included in your proxy group? 15
A45. I began with the group of 10 companies that Value Line classifies as Natural Gas 16
Distribution Utilities and applied the following screening criteria to select 17
companies that: 18

36
• pay consistent quarterly cash dividends, because companies that do not 1
cannot be analyzed using the Constant Growth DCF model; 2
• have investment grade long-term issuer ratings from S&P and/or Moody’s; 3
• are covered by at least two utility industry analysts; 4
• have positive long-term earnings growth forecasts from at least two utility 5
industry equity analysts; 6
• derive more than 70.00 percent of their total operating income from 7
regulated operations; 8
• derive more than 60.00 percent of regulated operating income from gas 9
distribution operations; and 10
• were not parties to a merger or transformative transaction during the 11
analytical periods relied on. 12
Q46. Did you eliminate any other companies that otherwise met your screening 13
criteria? 14
A46. Yes. On September 13, 2018, Columbia Gas of Massachusetts, a wholly-owned 15
subsidiary of NiSource Inc. (“NiSource”) experienced a significant event as a result 16
of over pressured lines on their system. The market response to this incident was 17
immediate. In fact, NiSource’s stock price fell approximately 12.00 percent 18
immediately following the incident. The total cost to NiSource for this event is 19
not yet defined. Given the impact the incident had on the stock price of NiSource, 20
and the potential effect on the company’s financial performance, it is appropriate 21
to exclude NiSource from my proxy group. 22

COST OF EQUITY ESTIMATION 6
Q48. Please briefly discuss the ROE in the context of the regulated rate of return. 7
A48. The overall ROR for a regulated utility is based on its weighted average cost of 8
capital, in which the cost rates of the individual sources of capital are weighted by 9
their respective book values. While the costs of debt and preferred stock can be 10
directly observed, the cost of equity is market-based and, therefore, must be 11
estimated based on observable market data. 12
Q49. How is the required ROE determined? 13
A49. The required ROE is estimated by using one or more analytical techniques that rely 14
on market-based data to quantify investor expectations regarding required equity 15
returns, adjusted for certain incremental costs and risks. Informed judgment is then 16
38
applied to determine where the company’s cost of equity falls within the range of 1
results. The key consideration in determining the cost of equity is to ensure that 2
the methodologies employed reasonably reflect investors’ views of the financial 3
markets in general, as well as the subject company (in the context of the proxy 4
group), in particular. 5
Q50. What methods did you use to determine Montana-Dakota’s ROE? 6
A50. I considered the results of the Constant Growth DCF model, the CAPM model, the 7
Bond Yield Plus Risk Premium methodology and an Expected Earnings analysis. 8
As discussed in more detail below, a reasonable ROE estimate appropriately 9
considers alternative methodologies and the reasonableness of their individual and 10
collective results. 11
A. Importance of Multiple Analytical Approaches 12
Q51. Why is it important to use more than one analytical approach? 13
A51. Because the cost of equity is not directly observable, it must be estimated based on 14
both quantitative and qualitative information. When faced with the task of 15
estimating the cost of equity, analysts and investors are inclined to gather and 16
evaluate as much relevant data as reasonably can be analyzed. Several models have 17
been developed to estimate the cost of equity, and I use multiple approaches to 18
estimate the cost of equity. As a practical matter, however, all of the models 19
available for estimating the cost of equity are subject to limiting assumptions or 20
other methodological constraints. Consequently, many well-regarded finance texts 21
recommend using multiple approaches when estimating the cost of equity. For 22
39
example, Copeland, Koller, and Murrin41 suggest using the CAPM and Arbitrage 1
Pricing Theory model, while Brigham and Gapenski42 recommend the CAPM, 2
DCF, and Bond Yield Plus Risk Premium approaches. 3
Q52. Is it important given the current market conditions to use more than one 4
analytical approach? 5
A52. Yes. As discussed in Section IV above, the U.S. economy is beginning to emerge 6
from an unprecedented period of low interest rates. Low interest rates, and the 7
effects of the investor “flight to quality” can be seen in high utility share valuations, 8
relative to historical levels and relative to the broader market. Higher utility stock 9
valuations produce lower dividend yields and result in lower cost of equity 10
estimates from a DCF analysis. Low interest rates also impact the CAPM in two 11
ways: (1) the risk-free rate is lower, and (2) because the market risk premium is a 12
function of interest rates, (i.e., it is the return on the broad stock market less the 13
risk-free interest rate), the risk premium should move higher when interest rates are 14
lower. Therefore, it is important to use multiple analytical approaches to moderate 15
the impact that the current low interest rate environment is having on the ROE 16
estimates for the proxy group and, where possible, consider using projected market 17
data in the models to estimate the return for the forward-looking period. 18

Q53. Are you aware of any regulatory commissions who have recognized that recent 1
conditions in capital markets are causing ROE recommendations based on 2
DCF models to be unreasonable? 3
A53. Yes, several regulatory commissions have addressed the effect of capital market 4
conditions on the DCF model, including FERC, the ICC, the PPUC and the 5
Missouri PSC. 6
Q54. Please summarize how the FERC has responded to the effect of market 7
conditions on the DCF. 8
A54. Understanding the important role that dividend yields play in the DCF model, the 9
FERC determined that capital market conditions have caused the DCF model to 10
understate equity costs for regulated utilities. In Opinion No. 531, the FERC noted: 11
There is ‘model risk’ associated with the excessive reliance or 12 mechanical application of a model when the surrounding 13 conditions are outside of the normal range. ‘Model risk’ is the 14 risk that a theoretical model that is used to value real world 15 transactions fails to predict or represent the real phenomenon 16 that is being modeled.43 17
In Opinion No. 531, the FERC also noted that the low interest rates and bond yields 18
that persisted throughout the analytical period that was relied on (study period) had 19
affected the results of the DCF model and recognized the need to move away from 20
the midpoint of the DCF analysis. In that case, the FERC relied on the CAPM and 21
other risk premium methodologies to inform its judgment to set the return above 22
43 FERC Docket No. EL11-66-001, Opinion No. 531 (June 19, 2014), fn 286.
41
the midpoint of the DCF results. These positions were affirmed by the FERC in 1
Opinion No. 551 in September 2016. 44 2
Finally, in October 2018, the FERC issued an Order in response to the remand from 3
the U.S. Court of Appeals for the District of Columbia indicating plans to establish 4
ROEs based on an equal weighting of the results of four financial models: the DCF, 5
CAPM, Expected Earnings and Risk Premium. FERC explains its reasons for 6
moving away from sole reliance on the DCF model as follows: 7
Our decision to rely on multiple methodologies in these four 8 complaint proceedings is based on our conclusion that the 9 DCF methodology may no longer singularly reflect how 10 investors make their decisions. We believe that, since we 11 adopted the DCF methodology as our sole method for 12 determining utility ROEs in the 1980s, investors have 13 increasingly used a diverse set of data sources and models to 14 inform their investment decisions. Investors appear to base 15 their decisions on numerous data points and models, including 16 the DCF, CAPM, Risk Premium, and Expected Earnings 17 methodologies. As demonstrated in Figure 2 below, which 18 shows the ROE results from the four models over the four test 19 periods at issue in this proceeding, these models do not 20 correlate such that the DCF methodology captures the other 21 methodologies. In fact, in some instances, their cost of equity 22 estimates may move in opposite directions over time. 23 Although we recognize the greater administrative burden on 24 parties and the Commission to evaluate multiple models, we 25 believe that the DCF methodology alone no longer captures 26 how investors view utility returns because investors do not 27 rely on the DCF alone and the other methods used by investors 28 do not necessarily produce the same results as the DCF. 29 Consequently, it is appropriate for our analysis to consider a 30 combination of the DCF, CAPM, Risk Premium, and 31 Expected Earnings approaches.45 32

42
Q55. How have the PPUC, the ICC and the Missouri PSC addressed the effect of 1
market conditions on the DCF? 2
A55. In a 2012 decision for PPL Electric Utilities, while noting that the PPUC has 3
traditionally relied primarily on the DCF method to estimate the cost of equity for 4
regulated utilities, the PPUC recognized that market conditions were causing the 5
DCF model to produce results that were much lower than other models such as the 6
CAPM and Bond Yield Plus Risk Premium. The PPUC’s Order supported the 7
consideration of multiple ROE estimation methodologies.46 8
The PPUC ultimately concluded: 9
As such, where evidence based on the CAPM and RP methods 10 suggest that the DCF-only results may understate the utility’s 11 current cost of equity capital, we will give consideration to 12 those other methods, to some degree, in determining the 13 appropriate range of reasonableness for our equity return 14 determination.47 15
In a recent ICC case, Docket No. 16-0093, Staff relied on a DCF analysis that 16
resulted in average returns for their proxy groups of 7.24 percent to 7.51 percent. 17
The company demonstrated that these results were uncharacteristically too low, by 18
comparing the results of Staff’s models to recently authorized ROEs for regulated 19
utilities and the return on the S&P 500.48 In Order No. 16-0093, the ICC agreed 20
with the Company that Staff's proposed ROE of 8.04 percent was anomalous and 21

43
recognized that a return that is not competitive will deter investment in Illinois.49 1
In setting the return in this proceeding the ICC recognized that it was necessary to 2
consider other factors beyond the outputs of the financial models, particularly 3
whether or not the return is sufficient to attract capital, maintain financial integrity, 4
and is commensurate with returns for companies of comparable risk, while 5
balancing the interests of customers and shareholders.50 6
Finally, in February 2018, the Missouri PSC issued a decision in Spire’s 2017 gas 7
rate case, in which the allowed ROE was set at 9.80 percent. In explaining the 8
rationale for its decision, the Commission cited the importance of considering 9
multiple methodologies to estimate the cost of equity and the need for the 10
authorized ROE to be consistent with returns in other jurisdictions and to reflect 11
the growing economy and investor expectations for higher interest rates. 12
Based on the competent and substantial evidence in the record, 13 on its analysis of the expert testimony offered by the parties, 14 and on its balancing of the interests of the company’s 15 ratepayers and shareholders, as fully explained in its findings 16 of fact and conclusions of law, the Commission finds that 9.8 17 percent is a fair and reasonable return on equity for Spire 18 Missouri. That rate is nearly the midpoint of all the experts’ 19 recommendations and is consistent with the national average, 20 the growing economy, and the anticipated increasing interest 21 rates. The Commission finds that this rate of return will allow 22 Spire Missouri to compete in the capital market for the funds 23 needed to maintain its financial health.51 24
49 Illinois Staff’s analysis and recommendation in that proceeding were based on its application of the
multi-stage DCF model and the CAPM to a proxy group of water utilities. 50 State of Illinois Commerce Commission Decision, Docket No. 16-0093, Illinois-American Water
Company, 2016 WL 7325212 (2016), at 55. 51 File No. GR-2017-0215 and File No. GR-2017-0216, Missouri Public Service Commission, Report
and Order, Issue Date February 21, 2018, at 34.
44
Q56. Has the Commission made similar findings regarding the reliance on multiple 1
models? 2
A56. Yes. It is my understanding that the Commission has emphasized that “[t]he 3
determination of cost of capital in rate proceedings, as noted above, combines 4
economic science, economic art and sound judgment as to what yields the most 5
reasonable result.”52 Moreover, in Docket No. 20000-ER-02-184, the Commission 6
concluded that the ROE should not be set based on one specific model or a variation 7
of a specific model and encouraged the evolution of economic thought be presented 8
in future cases.53 9
Q57. What are your conclusions about the results of the DCF and CAPM models? 10
A57. Recent market data that is used as the basis for the assumptions for both models 11
have been affected by market conditions. As a result, relying exclusively on 12
historical assumptions in these models, without considering whether these 13
assumptions are consistent with investors’ future expectations, will underestimate 14
the cost of equity that investors would require over the period that the rates in this 15
case are to be in effect. In this instance, relying on the historical average of 16
abnormally high stock prices results in low dividend yields that are not expected to 17
continue over the period that the new rates will be in effect. This, in turn, 18
underestimates the ROE for the rate period. 19
The use of recent historical Treasury bond yields in the CAPM also tends to 20
underestimate the projected cost of equity. Recent experience indicates that interest 21
52 PacifiCorp, Docket No. 20000-ER-03-198, Order, February 28, 2004, at ¶ 34 b1. 53 PacifiCorp, Docket No. 20000-ER-02-184, Order, March 6, 2003, at ¶ 260.
45
rates are increasing. The expectation that bond yields will not remain at currently 1
low levels means that the expected cost of equity would be higher than is suggested 2
by the CAPM using historical average yields. The use of projected yields on 3
Treasury bonds results in CAPM estimates that are more reflective of the market 4
conditions that investors expect during the period that the Company’s rates will be 5
in effect. 6
B. Constant Growth DCF Model 7
Q58. Please describe the DCF approach. 8
A58. The DCF approach is based on the theory that a stock’s current price represents the 9
present value of all expected future cash flows. In its most general form, the DCF 10
model is expressed as follows: 11
[1] 12
Where P0 represents the current stock price, D1…D∞ are all expected future 13
dividends, and k is the discount rate, or required ROE. Equation [1] is a standard 14
present value calculation that can be simplified and rearranged into the following 15
form: 16
[2] 17
Equation [2] is often referred to as the Constant Growth DCF model in which the 18
first term is the expected dividend yield and the second term is the expected long-19
term growth rate. 20

Q59. What assumptions are required for the Constant Growth DCF model? 1
A59. The Constant Growth DCF model requires the following four assumptions: (1) a 2
constant growth rate for earnings and dividends; (2) a stable dividend payout ratio; 3
(3) a constant price-to-earnings ratio; and (4) a discount rate greater than the 4
expected growth rate. To the extent that any of these assumptions is violated, 5
considered judgment and/or specific adjustments should be applied to the results. 6
Q60. What market data did you use to calculate the dividend yield in your Constant 7
Growth DCF model? 8
A60. The dividend yield in my Constant Growth DCF model is based on the proxy 9
companies’ current annualized dividend and average closing stock prices over the 10
30-, 90-, and 180-trading days ended March 29, 2019. 11
Q61. Why did you use 30-, 90-, and 180-day averaging periods? 12
A61. In my Constant Growth DCF model, I use an average of recent trading days to 13
calculate the term P0 in the DCF model to ensure that the ROE is not skewed by 14
anomalous events that may affect stock prices on any given trading day. The 15
averaging period should also be reasonably representative of expected capital 16
market conditions over the long-term. However, the averaging periods that I use 17
rely on historical data that is not consistent with the forward-looking expectation 18
that interest rates will increase. Therefore, the results of my Constant Growth DCF 19
model using historical data may underestimate the forward-looking cost of equity. 20
As a result, I place more weight on the median to median-high results produced by 21
my Constant Growth DCF model. 22
47
Q62. Did you make any adjustments to the dividend yield to account for periodic 1
growth in dividends? 2
A62. Yes, I did. Because utility companies tend to increase their quarterly dividends at 3
different times throughout the year, it is reasonable to assume that dividend 4
increases will be evenly distributed over calendar quarters. Given that assumption, 5
it is reasonable to apply one-half of the expected annual dividend growth rate for 6
purposes of calculating the expected dividend yield component of the DCF model. 7
This adjustment ensures that the expected first year dividend yield is, on average, 8
representative of the coming twelve-month period, and does not overstate the 9
aggregated dividends to be paid during that time. 10
Q63. Why is it important to select appropriate measures of long-term growth in 11
applying the DCF model? 12
A63. In its Constant Growth form, the DCF model (i.e., Equation [2]) assumes a single 13
growth estimate in perpetuity. To reduce the long-term growth rate to a single 14
measure, one must assume a constant payout ratio, and that earnings per share, 15
dividends per share and book value per share all grow at the same constant rate. 16
Over the long run, however, dividend growth can only be sustained by earnings 17
growth. Therefore, it is important to incorporate a variety of sources of long-term 18
earnings growth rates into the Constant Growth DCF model. 19
Q64. Which sources of long-term earnings growth rates did you use? 20
A64. My Constant Growth DCF model incorporates three sources of long-term earnings 21
growth rates: (1) Zacks Investment Research; (2) Thomson First Call (provided by 22
Yahoo!Finance); and (3) Value Line Investment Survey. 23
48
C. Discounted Cash Flow Model Results 1
Q65. How did you calculate the range of results for the Constant Growth DCF 2
Model? 3
A65. I calculated the low result for my DCF models using the minimum growth rate (i.e., 4
the lowest of the First Call, Zacks, and Value Line earnings growth rates) for each 5
of the proxy group companies. Thus, the low result reflects the minimum DCF 6
result for the proxy group. I used a similar approach to calculate the high results, 7
using the highest growth rate for each proxy group company. The mean results 8
were calculated using the average growth rates from all sources. 9
Q66. Have you excluded any of the Constant Growth DCF results for individual 10
companies in your proxy group? 11
A66. Yes, I have. It is appropriate to exclude Constant Growth DCF results below a 12
specified threshold at which equity investors would consider such returns to provide 13
an insufficient return increment above long-term debt costs. The average credit 14
rating for the companies in my proxy group is A-/A3. The average yield on 15
Moody’s A-rated utility bonds for the 30 trading days ending March 29, 2019, was 16
4.18 percent. 54 As shown on Exhibit No.___(AEB-2), Schedule 4, I have 17
eliminated Constant Growth DCF results lower than 7.00% because such returns 18
would provide equity investors a risk premium only 282 basis points above A-rated 19
utility bonds. 20
54 Source: Bloomberg Professional.
49
Q67. Has the Office of Consumer Advocate (“OCA”) considered a low-end 1
threshold for ROE results? 2
A67. Yes. In Docket No. 20000-469-ER-15, OCA witness Mr. Ornelas indicated that 3
the results of his CAPM analysis which resulted in an ROE of 8.40 percent 4
represented the minimum authorized ROE that could be authorized in the 5
proceeding.55 However, Mr. Ornelas concluded that this absolute minimum ROE 6
of 8.40 percent would not be adequate to balance the interests of Rocky Mountain 7
Power Company.56 Specifically, Mr. Ornelas noted that: 8
I believe the results of my CAPM (8.40%) represent the 9 absolute minimum cost of equity which could be authorized in 10 this proceeding. However, establishing the cost of equity at its 11 absolute minimum does not adequately balance the interests of 12 RMP and could discourage continued investment which is 13 necessary for the provision of safe and reliable service. 14 Therefore, I have looked primarily toward the remaining DCF 15 estimates to base my recommendation.57 16
Thus, the OCA determined that an ROE of 8.40 percent would not provide a 17
sufficient risk premium to compensate investors for the additional risk of an equity 18
investment. As shown in Exhibit __(AEB-2), Schedule 4, the 30-day average mean 19
ROE result using the low growth rate scenario would have been 7.34 percent prior 20
to my exclusion of the low-end outliers and would have been eliminated based on 21
the OCA’s criterion. Therefore, the low-end screen of 7.00 percent that I have 22
applied to the individual results of my Constant Growth DCF analysis is generally 23

Office of Consumer Advocate, July 28, 2015, at 31. 56 Ibid. 57 Ibid.
50
consistent with the OCA’s position and well below the minimum threshold outlined 1
by the OCA above in the case for Rocky Mountain Power Company. 2
Q68. What were the results of your DCF analyses? 3
A68. Figure 8 summarizes the results of my DCF analyses. As shown in Figure 8, the 4
median DCF results range from 9.10 percent to 9.30 percent and the median high 5
results are in the range of 11.12 percent to 11.22 percent. While I also summarize 6
the median low DCF results, I do not believe that the low DCF results provide a 7
reasonable spread over the expected yields on Treasury bonds to compensate 8
investors for the incremental risk related to an equity investment. 9

Q69. What are your conclusions about the results of the DCF models? 11
A69. As discussed previously, one primary assumption of the DCF models is a constant 12
P/E ratio. That assumption is heavily influenced by the market price of utility 13
stocks. To the extent that utility valuations are high and may not be sustainable, it 14
is important to consider the results of the DCF models with caution. As I indicated 15
previously, this is due to the high utility equity valuations that occurred in the lower 16
interest rate environment as investors have sought higher returns. With the 17
expectation of rising long-term interest rates, such levels are not expected to be 18
sustained in the upcoming years. Because the low dividend yields may result in the 19
58 See Exhibit No.___(AEB-2), Schedule 4.
51
DCF model understating investors’ expected return, I have given primary weight 1
to the median and high-end DCF results. My overall recommendation also relies 2
on the results of other ROE estimation models. 3
D. CAPM Analysis 4
Q70. Please briefly describe the Capital Asset Pricing Model. 5
A70. The CAPM is a risk premium approach that estimates the cost of equity for a given 6
security as a function of a risk-free return plus a risk premium to compensate 7
investors for the non-diversifiable or “systematic” risk of that security. This second 8
component is the product of the market risk premium and the Beta coefficient, 9
which measures the relative riskiness of the security being evaluated. 10
The CAPM is defined by four components, each of which must theoretically be a 11
forward-looking estimate: 12
[3] 13 Where: 14
Ke = the required market ROE; 15
β = Beta coefficient of an individual security; 16
rf = the risk-free rate of return; and 17
rm = the required return on the market. 18
In this specification, the term (rm – rf) represents the market risk premium. 19
According to the theory underlying the CAPM, because unsystematic risk can be 20
( )fmfe rrrK −+= β
52
diversified away, investors should only be concerned with systematic or non-1
diversifiable risk. Non-diversifiable risk is measured by Beta, which is defined as: 2
β = Covariance(re,
rm) [4] Variance(rm)
The variance of the market return (i.e., Variance (rm)) is a measure of the 3
uncertainty of the general market, and the covariance between the return on a 4
specific security and the general market (i.e., Covariance (re, rm)) reflects the extent 5
to which the return on that security will respond to a given change in the general 6
market return. Thus, Beta represents the risk of the security relative to the general 7
market. 8
Q71. What risk-free rate did you use in your CAPM analysis? 9
A71. I relied on three sources for my estimate of the risk-free rate: (1) the current 30-day 10
average yield on 30-year U.S. Treasury bonds of 2.99 percent;59 (2) the average 11
projected 30-year U.S. Treasury bond yield for Q3 2019 through Q3 2020 of 3.16 12
percent;60 and (3) the average projected 30-year U.S. Treasury bond yield for 2020 13
through 2024 of 3.90 percent.61 14
Q72. Would you place more weight on one of these scenarios? 15
A72. Yes. Based on current market conditions, I place more weight on the results of the 16
projected yields on the 30-year Treasury bonds. As discussed previously, the 17
estimation of the cost of equity in this case should be forward looking because it is 18
59 Bloomberg Professional, as of March 29, 2019. 60 Blue Chip Financial Forecasts, Vol. 38, No. 4, April 1, 2019, at 2. 61 Blue Chip Financial Forecasts, Vol. 37, No. 12, December 1, 2018, at 14.
53
the return that investors would receive over the future rate period. Therefore, the 1
inputs and assumptions used in the CAPM analysis should reflect the expectations 2
of the market at that time. As discussed above, leading economists surveyed by 3
Blue Chip are expecting an increase in long-term interest rates over the next five 4
years. This is an important consideration for equity investors as they assess their 5
return requirements. While I have included the results of a CAPM analysis that 6
relies on the current average risk-free rate, this analysis fails to take into 7
consideration the effect of the market’s expectations for interest rate increases on 8
the cost of equity. 9
Q73. What Beta coefficients did you use in your CAPM analysis? 10
A73. As shown on Exhibit No.___(AEB-2), Schedule 5, I used the average Beta 11
coefficients for the proxy group companies as reported by Bloomberg and Value 12
Line. The Beta coefficients reported by Bloomberg were calculated using ten years 13
of weekly returns relative to the S&P 500 Index. Value Line’s calculation is based 14
on five years of weekly returns relative to the New York Stock Exchange 15
Composite Index. 16
Q74. Why did you select a ten-year period to calculate the Beta coefficients from 17
Bloomberg? 18
A74. As I discussed in Section IV, the TCJA has had a significant effect on utility 19
companies. While other industries are able to retain the benefits of a reduced 20
corporate income tax rate, this benefit has largely been passed through to customers 21
by utility companies. This fundamental difference affected investors’ view of the 22
utility industry relative to other industries. As shown in Figure 9, after the Senate 23
54
passed the TCJA on December 2, 2017, utilities significantly deviated from the 1
broader market. 2
Figure 9: Performance of the Utility Industry Relative to the S&P 500 3
4 The TCJA’s effect on the utility industry relative to other industries caused a short-5
term significant shift in the returns on the utility industry relative to the broader 6
market. Over the last three to five years, volatility for the utility industry has been 7

Beta coefficients for utility companies. However, in short-term calculations of the 9
Beta coefficient, the significant effect of the shift in returns related to the TCJA has 10
outweighed the effect of longer-term measures of relative volatility. As such, to 11
reflect the long-term relationship that suggests utility stocks are less volatile than 12
the broader market (i.e. the relative volatility for utility companies has been lower 13

than the S&P 500 over the ten-year measure63), I selected a ten-year period to 1
calculate the Beta coefficients from Bloomberg. 2
Q75. How did you estimate the market risk premium in the CAPM? 3
A75. I estimated the market risk premium based on the expected return on S&P 500 4
Index less the yield on the 30-year Treasury bond. I calculate the expected return 5
on the S&P 500 Index companies for which dividend yields and long-term earnings 6
projections are available using the Constant Growth DCF model discussed earlier 7
in my Direct Testimony. Based on an estimated market capitalization-weighted 8
dividend yield of 2.00 percent and a weighted long-term growth rate of 11.69 9
percent, the estimated required market return for the S&P 500 Index is 13.80 10
percent. As shown in Exhibit No.___(AEB-2), Schedule 6, the implied market risk 11
premium over the current 30-day average of the 30-year U.S. Treasury bond yield, 12
and projected yields on the 30-year U.S. Treasury bond, range from 9.90 percent to 13
10.81 percent. 14
Q76. Have other regulators endorsed the use of a forward-looking market risk 15
premium? 16
A76. Yes. The FERC and the Staff in the Maine Public Utilities Commission (“Maine 17
PUC”) have supported the forward-looking market risk premium. In Opinion No. 18
531-B, the FERC specifically endorsed a method that is similar to the method I 19
have used to calculate the forward-looking market risk premium (i.e., applying a 20
63 Ibid.
56
Constant Growth DCF analysis to the S&P 500 and using the 30-year Treasury 1
bond yields).64 2
In response to arguments against this methodology, the FERC stated: 3
We are also unpersuaded that the growth rate projection in the 4 NETOs’ CAPM study was skewed by the NETOs’ reliance on 5 analysts’ projections of non-utility companies’ medium-term 6 earnings growth, or that the study failed to consider that those 7 analysts’ estimates reflect unsustainable short-term stock 8 repurchase programs and are not long-term projections. As 9 explained above, the NETOs based their growth rate input on 10 data from IBES, which the Commission has found to be a 11 reliable source of such data. Thus, the time periods used for 12 the growth rate projections in the NETOs’ CAPM study are 13 the time periods over which IBES forecasts earnings growth. 14 Petitioners’ arguments against the time period on which the 15 NETOs’ CAPM analysis is based are, in effect, arguments that 16 IBES data are insufficient in a CAPM study. 65 17
*** 18 While an individual company cannot be expected to sustain 19 high short term growth rates in perpetuity, the same cannot be 20 said for a stock index like the S&P 500 that is regularly 21 updated to contain only companies with high market 22 capitalization, and the record in this proceeding does not 23 indicate that the growth rate of the S&P 500 stock index is 24 unsustainable.66 25

calculating the market return that was proposed by the companies.67 In each case, 1
the market return was the expected return for the S&P 500 which was calculated 2
using a Constant Growth DCF model. In Docket No. 2017-00198, Staff noted the 3
following: 4
Staff has no issue with the methodology used by Mr. Perkins 5 in calculating market parameters based on the S&P 500 and 6 used the model provided by Mr. Perkins with the revised risk 7 free rate to re-calculate the market risk premiums.68 8
Furthermore, the Maine PUC in Docket No. 2017-0198 used the CAPM results 9
calculated by Staff and Emera Maine as a check on the reasonableness of the DCF 10
results in the case and did not dispute the use of the forward-looking market risk 11
premium by the parties (i.e., Staff and Emera Maine).69 12
Q77. What are the results of your CAPM analyses? 13
A77. As shown in Figure 10 (see also Exhibit No.___(AEB-2), Schedule 6), my CAPM 14
analysis produces a range of returns from 10.41 percent to 10.84 percent. The mean 15
returns using Bloomberg’s average Beta coefficient and three measures of the risk-16
free rate is 10.68 percent. Using the average Value Line Beta coefficient and three 17
measures of the risk-free rate, the mean result is 10.52 percent. 18

E. Bond Yield Plus Risk Premium Analysis 3
Q78. Please describe the Bond Yield Plus Risk Premium approach. 4
A78. In general terms, this approach is based on the fundamental principle that equity 5
investors bear the residual risk associated with equity ownership and therefore 6
require a premium over the return they would have earned as a bondholder. That 7
is, because returns to equity holders have greater risk than returns to bondholders, 8
equity investors must be compensated to bear that risk. Risk premium approaches, 9
therefore, estimate the cost of equity as the sum of the equity risk premium and the 10
yield on a particular class of bonds. In my analysis, I used actual authorized returns 11
for natural gas utility companies as the historical measure of the cost of equity to 12
determine the risk premium. 13
Q79. Are there other considerations that should be addressed in conducting this 14
analysis? 15
A79. Yes. It is important to recognize both academic literature and market evidence 16
indicating that the equity risk premium (as used in this approach) is inversely 17
related to the level of interest rates. That is, as interest rates increase (decrease), 18
the equity risk premium decreases (increases). Consequently, it is important to 19
develop an analysis that: (1) reflects the inverse relationship between interest rates 20
59
and the equity risk premium; and (2) relies on recent and expected market 1
conditions. Such an analysis can be developed based on a regression of the risk 2
premium as a function of U.S. Treasury bond yields. If we let authorized ROEs for 3
natural gas utilities serve as the measure of required equity returns and define the 4
yield on the long-term U.S. Treasury bond as the relevant measure of interest rates, 5
the risk premium simply would be the difference between those two points.70 6
Q80. Is the Bond Yield Plus Risk Premium analysis relevant to investors? 7
A80. Yes. Investors are aware of ROE awards in other jurisdictions, and they consider 8
those awards as a benchmark for a reasonable level of equity returns for utilities of 9
comparable risk operating in other jurisdictions. Because my Bond Yield Plus Risk 10
Premium analysis is based on authorized ROEs for utility companies relative to 11
corresponding Treasury yields, it provides relevant information to assess the return 12
expectations of investors. 13
Q81. What did your Bond Yield Plus Risk Premium analysis reveal? 14
A81. As shown in Figure 11 below, from 1992 through March 2019, there was a strong 15
negative relationship between risk premia and interest rates. To estimate that 16
relationship, I conducted a regression analysis using the following equation: 17
𝑅𝑅𝑅𝑅 = 𝑎𝑎 + 𝑏𝑏(𝑇𝑇) [5] 18 Where: 19
70 See e.g., S. Keith Berry, Interest Rate Risk and Utility Risk Premia during 1982-93, Managerial and
Decision Economics, Vol. 19, No. 2 (March, 1998), in which the author used a methodology similar to the regression approach described below, including using allowed ROEs as the relevant data source, and came to similar conclusions regarding the inverse relationship between risk premia and interest rates. See also Robert S. Harris, Using Analysts’ Growth Forecasts to Estimate Shareholders Required Rates of Return, Financial Management, Spring 1986, at 66.

premium would be 6.73 percent, resulting in an estimated ROE of 9.72 percent. 1
Based on the near-term (Q3 2019 – Q3 2020) projections of the 30-year U.S. 2
Treasury bond yield (i.e., 3.16 percent), the risk premium would be 6.64 percent, 3
resulting in an estimated ROE of 9.80 percent. Based on longer-term (2020-2024) 4
projections of the 30-year U.S. Treasury bond yield (i.e., 3.90 percent), the risk 5
premium would be 6.23 percent, resulting in an estimated ROE of 10.13 percent. 6
Q82. How did the results of the Bond Yield Risk Premium inform your 7
recommended ROE for Montana-Dakota? 8
A82. I have considered the results of the Bond Yield Risk Premium analysis in setting 9
my recommended ROE for Montana-Dakota. The results of both my CAPM and 10
Bond Yield Risk Premium analyses provide support for my view that the DCF 11
model is understating investors’ return requirements under current market 12
conditions. Also, as noted above, investors will consider the ROE award of a 13
company when assessing the risk of that company as compared to utilities of 14
comparable risk operating in other jurisdictions. The risk premium analysis takes 15
into account this comparison by estimating the return expectations of investors 16
based on the current and past ROE awards of gas utilities across the US. 17
F. Expected Earnings Analysis 18
Q83. Have you considered any additional analysis to estimate the cost of equity for 19
Montana-Dakota? 20
A83. Yes. I have considered an Expected Earnings analysis based on the projected ROEs 21
for each of the proxy group companies. 22
62
Q84. What is an Expected Earnings Analysis? 1
A84. The Expected Earnings methodology is a comparable earnings analysis that 2
calculates the earnings that an investor expects to receive on the book value of a 3
stock. The expected earnings analysis is a forward-looking estimate of investors’ 4
expected returns. The use of an Expected Earnings approach based on the proxy 5
companies provides a range of the expected returns on a group of risk comparable 6
companies to the subject company. This range is useful in helping to determine the 7
opportunity cost of investing in the subject company, which is relevant in 8
determining a company’s ROE. 9
Q85. Have regulators endorsed the use of an Expected Earnings Analysis? 10
A85. Yes. As discussed above, the FERC issued an Order in October 2018 indicating 11
plans to establish ROEs based on an equal weighting of the results of four financial 12
models: the DCF, CAPM, Expected Earnings and Risk Premium. In regard to the 13
expected earnings analysis, FERC noted the following: 14
A comparable earnings analysis is a method of calculating the 15 earnings an investor expects to receive on the book value of a 16 particular stock. The analysis can be either backward looking 17 using the company’s historical earnings on book value, as 18 reflected on the company’s accounting statements, or forward-19 looking using estimates of earnings on book value, as reflected 20 in analysts’ earnings forecasts for the company. The latter 21 approach is often referred to as an “Expected Earnings 22 analysis.” The returns on book equity that investors expect to 23 receive from a group of companies with risks comparable to 24 those of a particular utility are relevant to determining that 25 utility’s cost of equity, because those returns on book equity 26 help investors determine the opportunity cost of investing in 27 that particular utility instead of other companies of comparable 28 risk. Because investors rely on Expected Earnings analyses to 29 help estimate the opportunity cost of investing in a particular 30
63
utility, we find this type of analysis useful in determining a 1 utility’s ROE.72 2
Q86. Have any other regulators considered the use of an Expected Earnings 3
Analysis? 4
A86. Yes. The Washington Utilities & Transportation Commission (“Washington 5
UTC”), in its order in Dockets UE-170485 and UG-170486, considered the results 6
of the Comparable Earnings analysis 73 in establishing the authorized ROE for 7
Avista Corporation. The Washington UTC noted that it tends to place more weight 8
on the results of the DCF, CAPM and Risk Premium analyses; however, given the 9
wide range of CAPM results presented by the ROE witnesses in the case, the 10
Washington UTC decided to apply weight to the results of the Comparable 11
Earnings analysis.74 Specifically, the Washington UTC stated the following: 12
Finally, as additional data points for our consideration of 13 establishing Avista’s ROE, we note that two witness, Mr. 14 McKenzie for Avista and Mr. Parcell for Staff, employ the CE 15 approach to two proxy groups of companies. The respective 16 mid-points of each witnesses’ CE analysis are 10.5 and 9.5 17 percent, respectively, with an average of 10.0 percent. 18 Although we generally do not apply material weight to the CE 19 method, having stronger reliance on the DCF, CAPM and RP 20 methods, we are inclined to include the CE method here given 21 the anomalous CAPM results described previously.75 22

issued October 16, 2018, at 42. 73 The Expected Earnings analysis is a form of the Comparable Earnings analysis that relies
exclusively on forward-looking projections. 74 Wash. Utils. & Transp. Comm’n v. Avista Corp., Docket Nos. UE-170485 and UG-170486, Order
07, ¶ 65 (April 26,2018). 75 Ibid.
64
Q87. How did you develop the Expected Earnings Approach? 1
A87. I relied primarily on the projected ROE capital for the proxy companies as reported 2
by Value Line for the period from 2022-2024. The projected ROEs are adjusted to 3
account for the fact that the ROEs reported by Value Line are calculated on the 4
basis of common shares outstanding at the end of the period, as opposed to average 5
shares outstanding over the period. This adjustment is consistent with FERC’s 6
methodology for the Expected Earnings analysis that was included in its October 7
2018 order. As shown in Exhibit No.___(AEB-2), Schedule 8, the Expected 8
Earnings analysis results in a mean of 11.04 percent and a median of 10.66 percent. 9
REGULATORY AND BUSINESS RISKS 10
Q88. Do the median DCF and mean CAPM, Risk Premium and Expected Earnings 11
results for the proxy group, taken alone, provide an appropriate estimate of 12
the cost of equity for Montana-Dakota? 13
A88. No. These results provide only a range of the appropriate estimate of the 14
Company’s cost of equity. There are several additional factors that must be taken 15
into consideration when determining where the Company’s cost of equity falls 16
within the range of results. These factors, which are discussed below, should be 17
considered with respect to their overall effect on the Company’s risk profile. 18
A. Small Size Risk 19
Q89. Please explain the risk associated with small size. 20
A89. Both the financial and academic communities have long accepted the proposition 21
that the cost of equity for small firms is subject to a “size effect.” While empirical 22
65
evidence of the size effect often is based on studies of industries other than 1
regulated utilities, utility analysts also have noted the risk associated with small 2
market capitalizations. Specifically, an analyst for Ibbotson Associates noted: 3
For small utilities, investors face additional obstacles, such as 4 a smaller customer base, limited financial resources, and a lack 5 of diversification across customers, energy sources, and 6 geography. These obstacles imply a higher investor return.76 7
Q90. How does the smaller size of a utility affect its business risk? 8
A90. In general, smaller companies are less able to withstand adverse events that affect 9
their revenues and expenses. The impact of weather variability, the loss of large 10
customers to bypass opportunities, or the destruction of demand as a result of 11
general macroeconomic conditions or fuel price volatility will have a 12
proportionately greater impact on the earnings and cash flow volatility of smaller 13
utilities. Similarly, capital expenditures for non-revenue producing investments, 14
such as system maintenance and replacements, will put proportionately greater 15
pressure on customer costs, potentially leading to customer attrition or demand 16
reduction. Taken together, these risks affect the return required by investors for 17
smaller companies. 18
Q91. How does Montana-Dakota’s natural gas distribution operations in Wyoming 19
compare in size to the proxy group companies? 20
A91. As noted previously, Montana-Dakota serves approximately 19,000 residential, 21
commercial and industrial customers in 9 communities and as of year-end 2018, 22
76 Michael Annin, Equity and the Small-Stock Effect, Public Utilities Fortnightly, October 15, 1995.
66
had net utility natural gas plant in Wyoming of approximately $16.89 million.77 1
Montana-Dakota’s natural gas distribution operations in Wyoming are substantially 2
smaller than the median for the proxy group companies in terms of market 3
capitalization. Exhibit No.___(AEB-2), Schedule 9 provides the actual market 4
capitalization for the proxy group companies and estimates the implied market 5
capitalization for Montana-Dakota (i.e., the implied market capitalization if 6
Montana-Dakota’s natural gas distribution operations in Wyoming were a stand-7
alone publicly-traded entity). To estimate the size of the Company’s market 8
capitalization relative to the proxy group, I calculated Montana-Dakota’s proposed 9
capital structure equity component of $18.06 million by multiplying Montana-10
Dakota’s test year rate base of $15.39 million by Montana-Dakota’s test year 11
common equity ratio of 52.076 percent. I then applied the median market-to-book 12
ratio for the proxy group of 2.25 to Montana-Dakota’s implied common equity 13
balance and arrived at an implied market capitalization of approximately $18.06 14
million, or 0.41 percent of the median market capitalization for the proxy group. 15
Q92. How did you estimate the size premium for Montana-Dakota? 16
A92. Given this relative size information, it is possible to estimate the impact of size on 17
the ROE for Montana-Dakota using Duff and Phelps data that estimates the stock 18
risk premia based on the size of a company’s market capitalization. As shown in 19
Exhibit No.___(AEB-2), Schedule 9, the median market capitalization of the proxy 20
group of approximately $4.36 billion corresponds to the fifth decile of the Duff and 21
77 Montana-Dakota Utilities, 2018 Annual Report to the Wyoming Public Service Commission, at 10,
18, 40 and Montana-Dakota Utilities Co., Wyoming Natural Gas Tariff, Communities Served.
67
Phelps market capitalization data. Based on Duff and Phelps’ analysis, that decile 1
corresponds to a size premium of 1.28 percent (i.e., 128 basis points). Montana-2
Dakota’s implied market capitalization of approximately $18.06 million falls 3
within the tenth decile, which comprises market capitalization levels up to $321.578 4
million and corresponds to a size premium of 5.22 percent (i.e., 522 basis points). 5
The difference between those size premia is 394 basis points (i.e., 5.22 percent 6
minus 1.28 percent). 7
Q93. Have regulators in other jurisdictions made a specific risk adjustment to the 8
ROE results based on a company’s small size? 9
A93. Yes. In Order No. 15, the Regulatory Commission of Alaska (“RCA”) concluded 10
that Alaska Electric Light and Power Company (“AEL&P”) was riskier than the 11
proxy group companies due to small size as well as other business risks. The RCA 12
did “not believe that adopting the upper end of the range of ROE analyses in this 13
case, without an explicit adjustment, would adequately compensate AEL&P for its 14
greater risk.”78 Thus, the RCA awarded AEL&P an ROE of 12.875 percent which 15
was 108 basis points above the highest return on equity estimate from any model 16
presented in the case.79 Similarly, in Order No. 19, the RCA noted that small size 17
as well as other business risks such as structural regulatory lag, weather risk, 18
alternative rate mechanisms, gas supply risk, geographic isolation and economic 19

68
conditions increased the risk of ENSTAR Natural Gas Company.80 Ultimately, the 1
RCA concluded that: 2
Although we agree that the risk factors identified by ENSTAR 3 increase its risk, we do not attempt to quantify the amount of 4 that increase. Rather, we take the factors into consideration 5 when evaluating the remainder of the record and the 6 recommendations presented by the parties. After applying our 7 reasoned judgment to the record, we find that 11.875% 8 represents a fair ROE for ENSTAR.81 9
Q94. How have you considered the smaller size of Montana-Dakota in your 10
recommendation? 11
A94. While I have estimated the effect of Montana-Dakota’s small size on the ROE, I 12
am not proposing a specific adjustment for this risk factor. Rather, I believe it is 13
important to consider the small size of Montana-Dakota’s natural gas distribution 14
operations in Wyoming in the determination of where, within the range of analytical 15
results, the Company’s required ROE falls. Therefore, the additional risk 16
associated with small size indicates that the Company’s ROE should be established 17
above the mean results for the proxy group companies. 18
B. Flotation Cost 19
Q95. What are flotation costs? 20
A95. Flotation costs are the costs associated with the sale of new issues of common stock. 21
These costs include out-of-pocket expenditures for preparation, filing, 22
underwriting, and other issuance costs. 23
80 Docket No. U-16-066, In the Matter of the Tariff Revision Designated as TA285-4 Filed by
ENSTAR Natural Gas Company, A Division of Semco Energy, Inc., Order entered September 22, 2017 (Order No. 19) at 50-52.
81 Ibid.
69
Q96. Why is it important to consider flotation costs in the allowed ROE? 1
A96. A regulated utility must have the opportunity to earn an ROE that is both 2
competitive and compensatory to attract and retain new investors. To the extent 3
that a company is denied the opportunity to recover prudently incurred flotation 4
costs, actual returns will fall short of expected (or required) returns, thereby diluting 5
equity share value. 6
Q97. Are flotation costs part of the utility’s invested costs or part of the utility’s 7
expenses? 8
A97. Flotation costs are part of the invested costs of the utility, which are properly 9
reflected on the balance sheet under “paid in capital.” They are not current 10
expenses, and, therefore, are not reflected on the income statement. Rather, like 11
investments in rate base or the issuance costs of long-term debt, flotation costs are 12
incurred over time. As a result, the great majority of a utility’s flotation cost is 13
incurred prior to the test year but remains part of the cost structure that exists during 14
the test year and beyond, and as such, should be recognized for ratemaking 15
purposes. Therefore, whether an issuance occurs during the test year, or is planned 16
for the test year, is irrelevant, because failure to allow recovery of past flotation 17
costs may deny Montana-Dakota the opportunity to earn its required ROR in the 18
future. 19
Q98. Please provide an example of why a flotation cost adjustment is necessary to 20
compensate investors for the capital they have invested. 21
A98. Suppose MDU Resources issues stock with a value of $100, and an equity investor 22
invests $100 in MDU Resources in exchange for that stock. Further suppose that, 23
70
after paying the flotation costs associated with the equity issuance, which include 1
fees paid to underwriters and attorneys, among others, MDU Resources ends up 2
with only $97 of issuance proceeds, rather than the $100 the investor contributed. 3
MDU Resources invests that $97 in plant used to serve its customers, which 4
becomes part of rate base. Absent a flotation cost adjustment, the investor will 5
thereafter earn a return on only the $97 invested in rate base, even though she 6
contributed $100. Making a small flotation cost adjustment gives the investor a 7
reasonable opportunity to earn the authorized return, rather than the lower return 8
that results when the authorized return is applied to an amount less than what the 9
investor contributed. 10
Q99. Is the date of MDU Resources last issued common equity important in the 11
determination of flotation costs? 12
A99. No. As shown in Exhibit No.___(AEB-2), Schedule 10, MDU Resources closed 13
on equity issuances of approximately $58 million and $54 million (for a total of 4.7 14
million shares of common stock) in November 2002 and February 2004, 15
respectively. The vintage of the issuance, however, is not particularly important 16
because the investor suffers a shortfall in every year that he should have a 17
reasonable opportunity to earn a return on the full amount of capital that he has 18
contributed. Returning to my earlier example, the investor who contributed $100 19
is entitled to a reasonable opportunity to earn a return on $100 not only in the first 20
year after the investment, but in every subsequent year in which he has the $100 21
invested. Leaving aside depreciation, which is dealt with separately, there is no 22
basis to conclude that the investor is entitled to earn a return on $100 in the first 23
71
year after issuance, but thereafter is entitled to earn a return on only $97. As long 1
as the $100 is invested, the investor should have a reasonable opportunity to earn a 2
return on the entire amount. 3
Q100. Is the need to consider flotation costs recognized by the academic and financial 4
communities? 5
A100. Yes. The need to reimburse shareholders for the lost returns associated with equity 6
issuance costs is recognized by the academic and financial communities in the same 7
spirit that investors are reimbursed for the costs of issuing debt. This treatment is 8
consistent with the philosophy of a fair ROR. According to Dr. Shannon Pratt: 9
Flotation costs occur when new issues of stock or debt are sold 10 to the public. The firm usually incurs several kinds of flotation 11 or transaction costs, which reduce the actual proceeds received 12 by the firm. Some of these are direct out-of-pocket outlays, 13 such as fees paid to underwriters, legal expenses, and 14 prospectus preparation costs. Because of this reduction in 15 proceeds, the firm’s required returns on these proceeds equate 16 to a higher return to compensate for the additional costs. 17 Flotation costs can be accounted for either by amortizing the 18 cost, thus reducing the cash flow to discount, or by 19 incorporating the cost into the cost of capital. Because 20 flotation costs are not typically applied to operating cash flow, 21 one must incorporate them into the cost of capital.82 22
Q101. How did you calculate the flotation costs for Montana-Dakota? 23
A101. My flotation cost calculation is based on the costs of issuing equity that were 24
incurred by MDU Resources in its two most recent common equity issuances. 25
Those issuance costs were applied to my proxy group. Based on the issuance costs 26
82 Shannon P. Pratt, Cost of Capital Estimation and Applications, Second Edition, at 220-221.
72
provided in Exhibit No.___(AEB-2), Schedule 10, flotation costs for Montana-1
Dakota are approximately 0.09 percent (i.e., 9 basis points) for the proxy group. 2
Q102. Do your final results include an adjustment for flotation cost recovery? 3
A102. No. I did not make an explicit adjustment for flotation costs to any of my 4
quantitative analyses. Rather, I provide the above result for consideration in my 5
recommended ROE, which reflects the range of results from my Constant Growth 6
DCF, CAPM, Risk Premium and Expected Earnings analyses. 7
C. Capital Expenditures 8
Q103. Please summarize the Company’s capital expenditure requirements. 9
A103. The Company’s current projections for 2019 through 2023 include approximately 10
$12.43 million in capital investments for the period.83 Based on the Company’s net 11
utility plant of approximately $17.07 million as of December 31, 2017,84 the $12.43 12
million anticipated capital expenditures are approximately 72.80 percent of 13
Montana-Dakota’s net utility plant as of December 31, 2017. 14
Q104. How is the Company’s risk profile affected by their substantial capital 15
expenditure requirements? 16
A104. As with any utility faced with substantial capital expenditure requirements, the 17
Company’s risk profile may be adversely affected in two significant and related 18
ways: (1) the heightened level of investment increases the risk of under recovery or 19
83 Data provided by Montana-Dakota Utilities Co. for Capital Expenditures 2019-2023. 84 Data provided by Montana-Dakota Utilities Co.
73
delayed recovery of the invested capital; and (2) an inadequate return would put 1
downward pressure on key credit metrics. 2
Q105. Do credit rating agencies recognize the risks associated with elevated levels of 3
capital expenditures? 4
A105. Yes, they do. From a credit perspective, the additional pressure on cash flows 5
associated with high levels of capital expenditures exerts corresponding pressure 6
on credit metrics and, therefore, credit ratings. To that point, S&P explains the 7
importance of regulatory support for large capital projects: 8
When applicable, a jurisdiction’s willingness to support large 9 capital projects with cash during construction is an important 10 aspect of our analysis. This is especially true when the project 11 represents a major addition to rate base and entails long lead 12 times and technological risks that make it susceptible to 13 construction delays. Broad support for all capital spending is 14 the most credit-sustaining. Support for only specific types of 15 capital spending, such as specific environmental projects or 16 system integrity plans, is less so, but still favorable for 17 creditors. Allowance of a cash return on construction work-18 in-progress or similar ratemaking methods historically were 19 extraordinary measures for use in unusual circumstances, but 20 when construction costs are rising, cash flow support could be 21 crucial to maintain credit quality through the spending 22 program. Even more favorable are those jurisdictions that 23 present an opportunity for a higher return on capital projects 24 as an incentive to investors.85 25
Therefore, to the extent that Montana-Dakota’s rates do not permit the opportunity 26
to recover its capital investments on a regular basis, the Company will face 27
increased recovery risk and thus increased pressure on its credit metrics. 28

74
Q106. How do Montana-Dakota’s capital expenditure requirements compare to 1
those of the proxy group companies? 2
A106. As shown in Exhibit No.___(AEB-2), Schedule 11, I calculated the ratio of 3
expected capital expenditures to net utility plant for Montana-Dakota and each of 4
the companies in the proxy group by dividing each company’s projected capital 5
expenditures for the period from 2019-2023 by its total net utility plant as of 6
December 31, 2017. As shown in Exhibit No.___(AEB-2), Schedule 11 (see also 7
Figure 12 below), Montana-Dakota’s ratio of capital expenditures as a percentage 8
of net utility plant of 72.80 percent is approximately 1.01 times the median for the 9
proxy group companies of 71.83 percent. This result indicates moderately elevated 10
risk relative to the companies in the proxy group. 11

Q107. Does Montana-Dakota have a capital tracking mechanism to recover the costs 1
associated with its capital expenditures plan between rate cases? 2
A107. No. Montana-Dakota currently has not requested approval to recover capital 3
investment costs between rate cases utilizing a capital tracking mechanism. 4
Therefore, Montana-Dakota depends entirely on rate case filings for capital cost 5
recovery. However, significant programs like Montana-Dakota’s that drive capital 6
expenditure requirements generally receive cost recovery through infrastructure 7
and capital trackers. As shown in Exhibit No.___(AEB-2), Schedule 12, 67.00 8
percent of the proxy group utilities recover costs through capital tracking 9
mechanisms. Since Montana-Dakota does not currently have a capital tracking 10
mechanism, Montana-Dakota’s risk relative to the proxy group is increased. 11
Q108. What are your conclusions regarding the effect of the Company’s capital 12
spending requirements on its risk profile and cost of capital? 13
A108. The Company’s capital expenditure requirements as a percentage of net utility plant 14
are significant and will continue over the next few years. Additionally, unlike a 15
number of the operating subsidiaries of the proxy group, Montana-Dakota does not 16
have a comprehensive capital tracking mechanism to recover the Company’s 17
projected capital expenditures. Therefore, Montana-Dakota’s significant capital 18
expenditures plan and limited ability to recover the capital investment on an as-19
incurred basis results in a risk profile that is greater than that of the proxy group 20
and supports an ROE toward the higher end of the reasonable range of ROEs. 21
76
D. Regulatory Risk 1
Q109. Please explain how the regulatory environment affects investors’ risk 2
assessments. 3
A109. The ratemaking process is premised on the principle that, for investors and 4
companies to commit the capital needed to provide safe and reliable utility service, 5
the subject utility must have the opportunity to recover the return of, and the 6
market-required return on, invested capital. Regulatory authorities recognize that 7
because utility operations are capital intensive, regulatory decisions should enable 8
the utility to attract capital at reasonable terms; doing so balances the long-term 9
interests of investors and customers. Montana-Dakota is no exception. They must 10
finance their operations and require the opportunity to earn a reasonable return on 11
their invested capital to maintain their financial profiles. In that respect, the 12
regulatory environment is one of the most important factors considered in both debt 13
and equity investors’ risk assessments. 14
From the perspective of debt investors, the authorized return should enable the 15
Company to generate the cash flow needed to meet their near-term financial 16
obligations, make the capital investments needed to maintain and expand their 17
systems, and maintain the necessary levels of liquidity to fund unexpected events. 18
This financial liquidity must be derived not only from internally generated funds, 19
but also by efficient access to capital markets. Moreover, because fixed income 20
investors have many investment alternatives, even within a given market sector, the 21
Company’s financial profiles must be adequate on a relative basis to ensure their 22
77
ability to attract capital under a variety of economic and financial market 1
conditions. 2
Equity investors require that the authorized return be adequate to provide a risk-3
comparable return on the equity portion of the Company’s capital investments. 4
Because equity investors are the residual claimants on the Company’s cash flows 5
(which is to say that the equity return is subordinate to interest payments), they are 6
particularly concerned with the strength of regulatory support and its effect on 7
future cash flows. 8
Q110. Please explain how credit rating agencies consider regulatory risk in 9
establishing a company’s credit rating. 10
A110. Both S&P and Moody’s consider the overall regulatory framework in establishing 11
credit ratings. Moody’s establishes credit ratings based on four key factors: (1) 12
regulatory framework; (2) the ability to recover costs and earn returns; (3) 13
diversification; and (4) financial strength, liquidity and key financial metrics. Of 14
these criteria, regulatory framework and the ability to recover costs and earn returns 15
are each given a broad rating factor of 25.00 percent. Therefore, Moody’s assigns 16
regulatory risk a 50.00 percent weighting in the overall assessment of business and 17
financial risk for regulated utilities.86 18
S&P also identifies the regulatory framework as an important factor in credit ratings 19
for regulated utilities, stating: “One significant aspect of regulatory risk that 20
86 Moody’s Investors Service, Rating Methodology: Regulated Electric and Gas Utilities, June 23,
2017, at 4.
78
influences credit quality is the regulatory environment in the jurisdictions in which 1
a utility operates.”87 S&P identifies four specific factors that it uses to assess the 2
credit implications of the regulatory jurisdictions of investor-owned regulated 3
utilities: (1) regulatory stability; (2) tariff-setting procedures and design; (3) 4
financial stability; and (4) regulatory independence and insulation.88 5
Q111. How does the regulatory environment in which a utility operates affect its 6
access to and cost of capital? 7
A111. The regulatory environment can significantly affect both the access to, and cost of 8
capital in several ways. First, the proportion and cost of debt capital available to 9
utility companies are influenced by the rating agencies’ assessment of the 10
regulatory environment. As noted by Moody’s, “[f]or rate regulated utilities, which 11
typically operate as a monopoly, the regulatory environment and how the utility 12
adapts to that environment are the most important credit considerations.” 89 13
Moody’s further highlighted the relevance of a stable and predictable regulatory 14
environment to a utility’s credit quality, noting: “[b]roadly speaking, the 15
Regulatory Framework is the foundation for how all the decisions that affect 16
utilities are made (including the setting of rates), as well as the predictability and 17
consistency of decision-making provided by that foundation.”90 18

Q112. Have you conducted any analysis of the regulatory framework in Wyoming 1
relative to the jurisdictions in which the companies in your proxy group 2
operate? 3
A112. Yes. I have evaluated the regulatory framework in Wyoming on four factors that 4
are important in terms of providing a regulated utility an opportunity to earn its 5
authorized ROE. These are: 1) test year convention (i.e., forecast vs. historical); 6
2) method for determining rate base (i.e., average vs. year-end); 3) use of revenue 7
decoupling mechanisms or other clauses that mitigate volumetric risk; and 4) 8
prevalence of capital cost recovery between rate cases. The results of this 9
regulatory risk assessment are shown in Exhibit No.___(AEB-2), Schedule 12 and 10
are summarized below. 11
Test year convention: Montana-Dakota uses a historical test year adjusted for 12
known and measurable changes in Wyoming, while 39.00 percent of the 13
operating companies held by the proxy group provide service in jurisdictions 14
that use a fully or partially forecast test year. Forecast test years have been relied 15
on for several years and produce cost estimates that are more reflective of future 16
costs which results in more accurate recovery of incurred costs and mitigates 17
the regulatory lag associated with historical test years. As Lowry, Hovde, 18
Getachew, and Makos explain in their 2010 report, Forward Test Years for US 19
Electric Utilities: 20
This report provides an in depth discussion of the test year 21 issue. It includes the results of empirical research which 22 explores why the unit costs of electric IOUs are rising and 23 shows that utilities operating under forward test years realize 24 higher returns on capital and have credit ratings that are 25
80
materially better than those of utilities operating under 1 historical test years. The research suggests that shifting to a 2 future test year is a prime strategy for rebuilding utility credit 3 ratings as insurance against an uncertain future.91 4
Rate Base: The Company’s rate base in Wyoming is determined using the year-5
end methodology. As shown in Exhibit No.___(AEB-2), Schedule 12, 61.00 6
percent of the operating companies held by proxy group have also relied on a 7
year-end rate base. The year-end methodology means that the rate base includes 8
capital additions that occurred in the second half of the test year and is more 9
reflective of net utility plant going forward. 10
Volumetric Risk: Montana-Dakota has protection against volumetric risk in 11
Wyoming through customer charges that recover a high percentage of the 12
Company’s fixed costs. By comparison, 89 percent of the operating companies 13
held by the proxy group have some form of protection against volumetric risk 14
either through a revenue decoupling mechanism or a weather normalization 15
adjustment clause. Therefore, these operating companies have a slightly better 16
opportunity to achieve their authorized return than Montana-Dakota does due 17
to more stable revenues and cash flows. 18
Capital Cost Recovery: As discussed above, Montana-Dakota does not have a 19
capital tracking mechanism to recover capital investment costs between rate 20
cases. However, 67 percent of the operating companies held by the proxy group 21
have some form of capital cost recovery mechanism in place. 22

Q113. Has RRA provided recent commentary regarding its regulatory ranking for 1
Wyoming? 2
A113. Yes. In May 2017, RRA updated its evaluation of the regulatory environment in 3
Wyoming and lowered the overall rating of this regulatory jurisdiction. RRA noted 4
that the regulatory climate was restrictive and that the authorized ROEs were below 5
industry averages. 6
The Wyoming regulatory climate is relatively restrictive from 7 an investor point of view. A majority of the base rate 8 proceedings that have come before the PSC have been 9 resolved via settlements, and the authorized ROEs in both 10 settled and fully litigated cases have generally approximated 11 or have been somewhat below prevailing industry averages. 12 Retail electric competition has not been implemented, and the 13 state's electric utilities have fuel and purchased power 14 mechanisms in place, some of which contain incentive 15 provisions. In addition, several of the state's utilities have 16 mechanisms in place that provide for expedited recovery of 17 demand-side management costs. The PSC has generally relied 18 on a year-end original-cost rate base for a historical test period, 19 updated to reflect known-and-measurable changes. In more 20 recent cases for PacifiCorp, the PSC permitted the company to 21 utilize test years that have contained forecasted data. While 22 earning a cash return on construction work in progress 23 associated with new generation projects is permitted, such 24 treatment has only been granted by the PSC on a limited basis. 25 In the gas regulatory sphere, retail customers are permitted to 26 select an alternative supplier, and the utilities have the ability 27 to recover stranded costs related to retail competition. Gas 28 supply costs for those customers that do not opt to be served 29 by an alternative supplier may be recovered through an 30 automatic adjustment mechanism, and the gas utilities operate 31 under incentive mechanisms that permit the companies to 32 retain a portion of gas cost savings relative to PSC-approved 33 benchmarks. In addition, the state's gas utilities operate under 34 a partial revenue decoupling mechanism. In May 2017, RRA 35 performed a comprehensive audit of its regulatory rankings. 36 The ranking accorded Wyoming was lowered as a result of this 37
82
process. RRA now accords Wyoming an Average/3 ranking, 1 versus the previous Average/2 ranking.92 2
Q114. What are your conclusions regarding the perceived risks related to the 3
Wyoming regulatory environment? 4
A114. As discussed throughout this section of my testimony, both Moody’s, and S&P 5
have identified the supportiveness of the regulatory environment as an important 6
consideration in developing their overall credit ratings for regulated utilities. 7
Considering the regulatory adjustment mechanisms, many of the companies in the 8
proxy group have slightly more timely cost recovery through forecasted test years, 9
year-end rate base, cost recovery trackers and revenue stabilization mechanisms 10
than Montana-Dakota has in Wyoming. In addition, RRA recently lowered its 11
regulatory ranking for Wyoming from an Average/2 to an Average/3 ranking. 12
Therefore, the average ROE for the proxy group would understate the return on 13
equity that an investor would require in Wyoming because the risks of timely and 14
full cost recovery are moderately greater for Montana-Dakota in Wyoming than for 15
the proxy group. For that reason, I conclude that the authorized ROE for Montana-16
Dakota should be higher than the proxy group mean. 17
CAPITAL STRUCTURE 18
Q115. Is the capital structure of the Company an important consideration in the 19
determination of the appropriate ROE? 20
A115. Yes, it is. Assuming other factors equal, a higher debt ratio increases the risk to 21
investors. For debt holders, higher debt ratios result in a greater portion of the 22
92 Regulatory Research Associates, Profile of Wyoming Public Commission, accessed May 7, 2019.
83
available cash flow being required to meet debt service, thereby increasing the risk 1
associated with the payments on debt. The result of increased risk is a higher 2
interest rate. The incremental risk of a higher debt ratio is more significant for 3
common equity shareholders. Common shareholders are the residual claimants on 4
the cash flow of the Company. Therefore, the greater the debt service requirement, 5
the less cash flow available for common equity holders. 6
Q116. What is Montana-Dakota’s proposed capital structure? 7
A116. The Company’s proposal is to establish a capital structure consisting of 52.076 8
percent common equity, 45.717 percent long-term debt and 2.207 percent short-9
term debt. 10
Q117. Did you conduct any analysis to determine if this requested equity ratio was 11
reasonable? 12
A117. Yes, I did. I reviewed the Company’s historical actual capital structure and the 13
capital structures of the utility operating subsidiaries of the proxy companies. 14
Because the ROE is set based on the return that is derived from the risk-comparable 15
proxy group, it is reasonable to look to the proxy group average capital structure to 16
benchmark the equity ratio for the Company. 17
Q118. Please discuss your analysis of the capital structures of the proxy group 18
companies. 19
A118. I calculated the mean proportions of common equity, long-term debt, short-term 20
debt and preferred equity for the most recent year for each of the companies in the 21
84
proxy group at the operating subsidiary level. 93 My analysis of the capital 1
structures of the proxy group companies is provided in Exhibit No.___(AEB-2), 2
Schedule 13. As shown in Exhibit No.___(AEB-2), Schedule 13, the equity ratios 3
for the proxy group at the operating utility company level ranged from 47.00 4
percent to 63.18 percent with an average of 52.94 percent. Montana-Dakota’s 5
proposed equity ratio of 52.076 percent is well within the range of equity ratios for 6
the utility operating subsidiaries of the proxy group companies and is therefore 7
reasonable. 8
Q119. Are there other factors to be considered in setting the Company’s capital 9
structure? 10
A119. Yes. The credit rating agencies’ response to the TCJA must also be considered 11
when determining the equity ratio. As discussed previously in my testimony, all 12
three rating agencies have noted that the TCJA has negative implications for utility 13
cash flows. S&P and FitchRatings have specifically identified increasing the equity 14
ratio as one approach to ensure that utilities have sufficient cash flows following 15
the tax cuts and the loss of bonus depreciation. Furthermore, Moody’s 16
unprecedented downgrade of the rating outlook for the entire utilities sector in June 17
2018 stresses the importance of maintaining adequate cash flow metrics for the 18
industry as a whole and Montana-Dakota in the context of this proceeding. 19
93 Source: SNL Financial and FERC Form 1 and FERC Form 2 annual reports.
85
Q120. Is there a relationship between the equity ratio and the authorized ROE? 1
A120. Yes. The equity ratio is the primary indicator of financial risk for a regulated utility 2
such as Montana-Dakota. To the extent the equity ratio is reduced, it is necessary 3
to increase the authorized ROE to compensate investors for the greater financial 4
risk associated with a lower equity ratio. 5
Q121. What is your conclusion regarding an appropriate capital structure for 6
Montana-Dakota? 7
A121. Considering the actual capital structures of the proxy group operating companies, I 8
believe that Montana-Dakota’s proposed common equity ratio of 52.076 percent is 9
reasonable. The proposed equity ratio is well within the range established by the 10
capital structures of the utility operating subsidiaries of the proxy companies. In 11
addition, based on the cash flow concerns raised by credit rating agencies as a result 12
of the TCJA, it is reasonable to rely on a higher equity ratio than the Company may 13
have relied on in prior. 14
CONCLUSIONS AND RECOMMENDATION 15
Q122. What is your conclusion regarding a fair ROE for Montana-Dakota? 16
A122. Based on the quantitative and qualitative analyses presented in my Direct 17
Testimony, and in light of the business and financial risks of Montana-Dakota 18
compared to the proxy group, and the effects of Federal tax reform on the cash flow 19
metrics of utilities, it is my view that an ROE of 10.30 percent is reasonable and 20
would fairly balance the interests of customers and shareholders. This ROE would 21
enable the Company to maintain its financial integrity and therefore its ability to 22
86
attract capital at reasonable rates under a variety of economic and financial market 1
conditions, while continuing to provide safe, reliable and affordable natural gas 2
utility service to customers in Wyoming. 3

Notes:[i] Offering Completion Date[ii] Underwriting discount was calculated as the market price minus the offering price when not explicitly given in the prospectus.
The flotation cost adjustment is derived by dividing the dividend yield by 1 − F (where F = flotation costs expressed in percentage terms), or by 0.9632, and adding that result to the constant growth rateto determine the cost of equity. Using the formulas shown previously in my testimony, the Constant Growth DCF calculation is modified as follows to accommodate an adjustment for flotation costs:

Q. What statements, schedules and exhibits are you sponsoring? 16
A. I am sponsoring Statements A through D, Statement F, Schedule F-17
1 and F-4, Statements G through J, Statement M, Purchased Gas Cost 18
Adjustment - Rate 88 and Exhibit No.___(TRJ-1). 19
Pro Forma Revenue Requirement 20
Q. What were the results of Wyoming gas operations for the twelve 21
months ended December 31, 2018? 22
3
A. Statement A, pages 2 and 4 show the per books income statement 1
and rate base for Wyoming. As shown on page 2, Wyoming gas 2
operations had a return on rate base of 5.052 percent and a return on 3
equity of 5.366 percent for the twelve months ended December 31, 2018. 4
The details for each line item (i.e. sales revenue, other revenue, etc.) are 5
included in the applicable Statement listed. Pages 3 and 5 list the pro 6
forma adjustments to operating revenues, expenses and rate base. All 7
adjustments were calculated on either a Wyoming specific basis or on a 8
total Company basis and allocated to Wyoming, as indicated on the 9
statement or schedule detailing each adjustment. 10
Q. How was the per books cost of service allocated to Wyoming? 11
A. The Company utilizes a jurisdictional accounting system that 12
directly assigns and/or allocates every item of revenue, expense and rate 13
base to the jurisdictions as part of the regular accounting process on a 14
monthly basis. The allocation methods and procedures are the same as 15
have previously been used in Commission proceedings and are based on 16
the principle of assigning and/or allocating costs to the cost causer. The 17
Company’s Cost Allocation Manual details the method of assigning costs 18
to the Wyoming gas operations and is included in Statement M. 19
Q. What criteria were used to determine the pro forma adjustments? 20
A. The pro forma adjustments to operating revenue, expenses and 21
rate base were based on known and measurable changes occurring by 22
December 31, 2019, conform to past Commission practices and are listed 23
4
on pages 3 and 5 of Statement A. All adjustments are reasonably certain 1
to occur and can be measured with reasonable accuracy, thus meeting the 2
criteria of known and measurable. 3
Q. Would you describe the pro forma adjustments to the income 4
statement and rate base? 5
A. Yes. The adjustments to the income statement are summarized on 6
Statement A, page 3 and consist of adjustments to revenue, operation and 7
maintenance expenses, depreciation expense, taxes other, and current 8
and deferred income taxes. The adjustments to rate base are 9
summarized on Statement A, page 5 and include plant, accumulated 10
reserve and associated additions and deductions. 11
Pro Forma Income Statement 12
Q. What adjustments were made to operating revenues? 13
A. The adjustments to operating revenues are contained in Statement 14
F. Retail sales and transportation revenues are presented in Schedule F-15
1. Adjustment No. 1 restates the per books consumption at current rates, 16
adjusted to reflect the March 2019 cost of gas, exclusive of the surcharge 17
adjustment, and eliminates the unbilled revenue and reserve for refunds, 18
increasing revenue by $700,555. 19
Adjustment No. 2 decreases revenues by $895,249 to reflect the 20
effect of normal weather on sales and transportation volumes, as weather 21
was 13.2 percent colder than normal in 2018. As discussed in Ms. 22
Kivisto’s testimony, Montana-Dakota is proposing to discontinue the non-23
5
core revenue credit in this filing. Therefore, interruptible volumes have 1
been included in the normalized revenues. 2
Adjustment No. 3 is an increase to revenues of $113,480 to reflect 3
the annualization of firm customers to the December 2018 level. 4
Interruptible volumes were based on two- or three-year average usage 5
and do not require annualization. 6
Montana-Dakota did not include customer growth within its revenue 7
analysis. The recent level of customer additions has been insignificant 8
and not reliably predictable. Because incremental customers and volumes 9
have not been included the Company has not included the associated 10
investment required to connect new customers. 11
Adjustment No. 4, presented in Schedule F-4, includes adjustments 12
to other operating revenues. The pro forma adjustment consists of the 13
adjustment to late payment revenue based on the three-year average ratio 14
of late payment revenues to sales and transportation revenue applied to 15
pro forma revenue, and a three-year average of reconnect fees, NSF 16
check fees, sale of junk material and penalty revenue. 17
Q. What adjustments were made to operations and maintenance (O&M) 18
expenses? 19
A. The adjustments to operation and maintenance expenses are 20
contained in Statement G with each adjustment set forth in Statement G, 21
Schedule G-1. 22
6
The $74,417 reduction to the cost of gas (Adjustment No. 5), 1
shown on page 4, uses the pro forma dk sales, adjusted for losses, and 2
the cost of gas calculated in the March 2019 Purchased Gas Cost 3
Adjustment. The distribution loss factor of 0.68 percent represents the 4
loss factor currently used in the Company’s cost of gas filings. 5
Q. How were the pro forma labor and benefits developed? 6
A. The adjustment to labor is Adjustment No. 6. The pro forma labor 7
was developed by applying a weighted average percentage increase in 8
labor costs to the actual 2018 Wyoming labor expense. Wages and 9
salaries for straight time, premium time and vacation were based on total 10
Company costs with the application of an increase of 2.92 percent for 11
union employees and 3.46 percent for nonunion employees effective in 12
2019 resulting in an overall increase in wages of 3.25 percent. Bonuses 13
and commissions have been adjusted to reflect ongoing stock 14
compensation and miscellaneous bonuses. In addition, incentive 15
compensation has been adjusted to reflect an average level of 11.05% of 16
straight time and vacation. These changes result in an overall increase in 17
labor of 5.84 percent, or $102,261. 18
Benefits are shown on page 6 of Schedule G-1. Adjustment No. 7 19
is an overall increase of $15,133 in benefits. Benefits expense consists of 20
medical/dental insurance, pension expense, post-retirement, 401-K, 21
workers compensation, and other benefits (primarily disability insurance). 22
7
Each of these items was adjusted individually using current information 1
and applying the percentage increase to each type of benefit. 2
Medical and dental expense is increasing 8.0 percent and is based 3
on the Company’s actual 2019 premium increase compared to 2018. 4
Pension expense is decreasing 45.05 percent based on the actuarial 5
results of the total Company pension estimates. Post-retirement expense 6
is increasing by 3.50 percent from 2018. The 401K expense, workers 7
compensation and other benefits are tied to labor costs and increase 3.25 8
percent to reflect the overall average increase in wages and salaries. 9
Q. Would you describe the other adjustments made to O&M expense? 10
A. Yes. Vehicles and work equipment (Adjustment No. 8) reflects all 11
expenses associated with the Company’s vehicles and work equipment, 12
such as backhoes, including the costs of fuel, insurance, maintenance and 13
depreciation expense. Adjustment No. 8 reflects an increase of $65,567 in 14
this account due to the change in the depreciation component of the 15
expense. It is calculated based on the pro forma vehicle and work 16
equipment investment and the depreciation rates in Statement H. The 17
depreciation component on these items is not charged to depreciation 18
expense but rather is charged to a clearing account where it is then 19
recorded in O&M expense as the vehicles or work equipment is used. 20
This method allows the Company to match the cost of vehicles or work 21
equipment to the service provided or as a component of the associated 22
capital investment. 23
8
Company consumption (Adjustment No. 9) is the expense for 1
electric and natural gas consumption in Company buildings. An overall 2
decrease of $927 reflects the electric volumes at current rates and the 3
normalized gas volumes at current rates. 4
Uncollectible accounts (Adjustment No. 10) is a decrease of $5,694 5
based on the ratio of the five-year average ratio of net write-offs to sales 6
and transportation revenues and applied to pro forma revenues. The 7
decrease is due to a slight decrease in the write-off ratio and revenues. 8
Postage expense (Adjustment No. 11) is a decrease of $592 and 9
reflects the annualized December 2018 e-billing (electronic billing) level, 10
partially offset by a 1.32 percent increase in postage rates effective 11
1/1/2019. 12
Advertising expense (Adjustment No. 12) is shown on page 11 and 13
represents a decrease of $9,276. Pursuant to Wyoming General 14
Regulations Section 248, general promotional and institutional advertising 15
expense has been eliminated. Informational advertising is adjusted to 16
exclude advertising not directly applicable to Wyoming gas operations. 17
Insurance expense (Adjustment No. 13) reflects the expense at 18
current levels for 2019 and represents an increase of $7,274. Self-19
insurance expense was adjusted to reflect a five-year average of claims 20
and related expenses paid. 21
9
Materials expense (Adjustment No. 14) is an increase of $9,982 1
and is adjusted to reflect an increase in materials associated with pipeline 2
safety and integrity replacement projects. 3
Software maintenance (Adjustment No. 15) is found on page 14 4
and is an increase of $20,983. The Pro Forma increase is related to 5
contract increases as well as the purchase of additional cyber security 6
software. 7
Industry dues (Adjustment No. 16) reflects the removal of dues not 8
applicable to Wyoming gas operations for a decrease of $654. All other 9
industry dues remain at the current level. 10
Regulatory Commission Expense (Adjustment No. 17) reflects a 11
three-year average of ongoing regulatory commission expenses, the 12
expenses expected to be incurred in this filing, amortized over a three-13
year period, and a five-year average of the costs of performing gas and 14
common depreciation studies. The adjustment is an increase of $48,812. 15
Adjustment No. 18 is related to the allocation of MDU Resources 16
Group, Inc. (MDUR) expenses (Corporate Charges). MDUR charges that 17
are not specifically allocable to Montana-Dakota, or another subsidiary of 18
MDUR, are allocated based on the average invested capital for each 19
subsidiary. A three-factor formula for corporate charges was 20
recommended by the Office of Consumer Advocate (OCA) in the 21
Settlement Agreement approved by the Commission in Docket No. 20004-22
117-ER-16. The three-factor formula is comprised of employees and 23
10
earnings in addition to average invested capital. Adjustment No. 18 1
reflects the application of the resulting three-factor formula and is a 2
decrease in expense of $77,834. 3
The items adjusted individually above represent approximately 90 4
percent of total Wyoming gas O&M, as shown on pages 19 through 21. 5
The remaining items, which make up approximately 2.4 percent of total 6
O&M, are assumed to remain flat. 7
Q. What adjustments were made to depreciation expense? 8
A. The adjustment to depreciation expense is contained in Statement 9
H. Adjustment No. 19, as shown in Schedule H-1, restates annual 10
depreciation expense to the pro forma level of plant in service and 11
proposed depreciation rates. The depreciation rates for distribution and 12
general plant are from a 2015 study prepared by AUS Associates. The 13
depreciation rates are shown in Statement Workpapers H1 – H4. The 14
proposed depreciation rates for common plant match the rates approved 15
in Docket No. 20004-117-ER-16. 16
On April 1, 2017, Montana-Dakota redeemed all outstanding 17
preferred stock. Preferred stock has characteristics of both debt and 18
equity. For instance, only $180,000 of the $685,000 in dividends paid 19
each year are deductible on the Company’s tax return. Similar to debt, 20
quarterly dividends paid are based on a stated rate of 4.5 and 4.7 percent. 21
$20 million of long-term debt issued in the first quarter of 2017 provided an 22
opportunity to redeem the preferred stock and replace it with long term 23
11
debt with a stated interest cost of 3.36 percent. At the same time, interest 1
on the debt outstanding is deductible for tax purposes which further 2
reduces the revenue requirement. The result of the redemption is a lower 3
overall cost of capital. 4
As discussed in the testimony of Ms. T. Nygard, a call premium of 5
$600,000 was incurred upon redemption of preferred stock. The call 6
premium has been deferred on the Company’s books. The Company is 7
now proposing to include this regulatory asset in its rate base and began 8
amortizing the balance over the life of the long-term debt of 15 years. An 9
analysis has been prepared which demonstrates the overall net benefit of 10
the redemption, inclusive of the rate base impact, is beneficial to Montana-11
Dakota’s customers. The analysis has been included in the Statement 12
Workpapers beginning on H5. This item has been reflected in the revenue 13
requirement in a manner similar to the unamortized loss on debt 14
Montana-Dakota began amortizing the preferred stock redemption 15
costs during 2018 and has included a pro forma adjustment to reflect the 16
annualization of the amortization as a part of Adjustment 19. 17
Q. What adjustments were made to taxes other than income? 18
A. The adjustments to taxes other than income are contained in 19
Statement I. Adjustment No. 20 restates ad valorem taxes to the pro 20
forma level of plant in service based on the 2018 ratio of ad valorem taxes 21
to plant. The net result is an increase of $4,056. 22
12
The adjustment to payroll taxes (Adjustment No. 21) is an increase 1
of $6,961 based on the ratio of payroll taxes to labor expense for 2018 2
applied to pro forma labor expense. 3
The Wyoming franchise taxes are restated to the pro forma 4
revenue levels by applying the composite franchise rate to pro forma 5
revenues. Likewise, the Wyoming Uniform Assessment tax is also 6
restated to reflect projected revenues and the tax rate effective July 1, 7
2018. Adjustment No. 22 is an increase of $62 and Adjustment No. 23 is a 8
decrease of $664. 9
All other taxes other than income remained at the 2018 level. 10
Q. Does this filing incorporate the changes resulting from the 11
enactment of The Tax Cuts and Jobs Act of 2017 (TCJA)? 12
A. The Tax Cuts and Jobs Act of 2017 (TCJA) was signed into law on 13
December 22, 2017 and incorporated a number of changes which 14
impacted Montana-Dakota’s Wyoming gas operations. The primary 15
impact of the TCJA is the reduction in the corporate income tax rate from 16
35 percent to 21 percent. The rate reduction has a two-fold effect: 17
• A reduction in prospective income taxes on the Company’s income 18
statement beginning January 1, 2018; and 19
• The Company was required to remeasure utility-related deferred 20
income taxes based on the 21 percent tax rate with a regulatory 21
liability established representing the difference between the old and 22
new tax rate and referred to as excess deferred taxes (EDITs). 23
13
As noted, 2018 was the first full year of the reduced income tax 1
rate. Therefore, the per books current and deferred tax calculations for 2
2018 were based on a 21 percent federal income tax rate. The per books 3
deferred income tax expense also reflected the actual EDIT amortizations 4
of all plant related EDITs based on the average rate assumption method 5
(ARAM) that occurred in 2018 as well as first year of straight line 6
amortization of non-plant related EDITs. 7
Q. What adjustments were made to income taxes? 8
A. The adjustments to income taxes are contained in Statement J. 9
The adjustment to current income tax (Adjustment No. 24) reflecting the 10
previously mentioned pro forma revenue and expense adjustment has 11
been calculated on Schedule J-1, page 1 of Statement J. Current income 12
tax expense also incorporates the adjustments to operating income for the 13
change in interest expense and book/tax differences related to 14
depreciation. 15
The adjustment to operating income to reflect the change in interest 16
expense (Adjustment No. 25) is shown on Schedule J-1, page 2. Interest 17
is deductible for tax purposes and interest expense is calculated on the 18
pro forma rate base using the weighted cost of debt and debt ratio from 19
Statement E. The resulting interest expense is an increase of $22,537 20
from the per books level. 21
14
The income tax expense adjustments for the difference between 1
book and tax depreciation and deferred income tax expense on the pro 2
forma plant additions are shown as Adjustment I on Schedule J-2, page 3. 3
The closing/filing and prior period adjustments in the current 4
income tax accrual and in the deferred taxes are eliminated in Adjustment 5
No. 26. Adjusted current and deferred income taxes match those 6
calculated for Wyoming and conform to past Commission practices. 7
As mentioned previously, the plant related EDITs are recognized 8
based on the ARAM method. The amortization does change each year 9
depending on the level of tax depreciation relative to the level of book 10
depreciation. The pro forma amount for the TCJA Excess DIT Plant – 11
ARAM is shown in Adjustment No. 27 on Schedule J-2, page 2 and is an 12
increase in the amortization to deferred taxes of $26,265. 13
Pro Forma Rate Base 14
Q. How was the rate base developed? 15
A. Per books and pro forma rate base for Wyoming gas operations is 16
summarized in Statement A, page 4. The pro forma rate base is based on 17
the year end 2018 rate base and reflects known and measurable 18
adjustments that will occur within twelve months of December 31, 2018. 19
The pro forma adjustments to rate base are summarized on Statement A, 20
page 5. 21
Statement B, page 1 summarizes the pro forma plant in service. 22
Adjustment A is the known and measurable plant additions that will be in 23
15
service by December 31, 2019. The additions of $1,751,297 include 1
additions to distribution, general and common plant and are shown on 2
Statement B, Schedule B-2, pages 1-3. 3
Projects that typically result in incremental customers and 4
associated volumes, labeled Growth Projects, have not been included in 5
the Company’s capital additions to plant as the level of customer additions 6
has typically been insignificant and not reliably predictable. In addition, 7
the Company’s extension policy should result in a matching level of 8
revenue to allow a reasonable return in the capital investments associated 9
with growth projects. 10
Adjustment B, shown in Statement C, increases the reserve for 11
depreciation on the per books plant by $1,712,591 to restate the reserve 12
to the pro forma level in order to match the pro forma plant levels. 13
Q. How were the pro forma adjustments to working capital derived? 14
A. The working capital items are shown in Statement D. Materials and 15
supplies are restated to a thirteen-month average balance, with actual 16
balances through December 31, 2018, in Adjustment C, for an increase of 17
$17,383. 18
Prepaid insurance expense is restated to a thirteen-month average 19
balance in Adjustment D with actual balances through December 31, 2018 20
Pro Forma balances reflect the 2018 levels of insurance expense and is 21
an increase of $30,414. 22
16
The unamortized loss on reacquired debt balance reflects the pro 1
forma 2019 amortization as well as the January 1, 2019 reallocation 2
adjustment and is included as Adjustment E. 3
Adjustment F is the Unamortized Redemption Cost of Preferred 4
Stock and is a decrease of $424 reflecting the pro forma amortization 5
based on a 15 year amortization. The 15 year amortization matches the 6
life of the long term debt that was used in the redemption of the preferred 7
stock. 8
As discussed in the testimony of Ms. Kivisto, the Company’s 9
required contributions to the pension account resulted in a significant 10
prepaid asset and exceeded the amount of pension expense (commonly 11
referred to as FAS 87 or ASC 715 expense) through the revenue 12
requirement. The contributions are tax deductible for Montana-Dakota 13
and any earnings on those contributions in the pension trust account are 14
not subject to income tax. With that in mind, the contributions help 15
maintain the required funding level and, at the same time, typically result 16
in lower FAS 87 expense. 17
Post retirement contributions are typically much more closely 18
matched to the annual expense, so the prepaid asset is much smaller. 19
However, Montana-Dakota considers the benefits and the circumstances 20
surrounding the creation of the prepaid assets or liabilities that it is 21
appropriate to include both pension and post retirement similarly. 22
17
Adjustments G and H are to add the Provision for Pension Benefits 1
of $2,021,350 and Provision for Post Retirements of $27,242 to rate base. 2
Although the 2018 per books amount was recorded on Montana-Dakota’s 3
books it has not been included in order to provide the return on rate base 4
comparable to the authorized rate base. 5
Q. Would you describe the deductions to rate base? 6
A. The adjustments to accumulated deferred income taxes are 7
summarized on Statement J, Schedule J-2, page 1. Adjustment I – 8
Liberalized Depreciation reflects the deferred income taxes related to the 9
2019 plant additions and book/tax differences for 2018 and prior vintage 10
assets and is shown on page 3. 11
Adjustment J shown on Schedule J-2, page 5 is associated with 12
excess deferred income taxes resulting from changes in tax rates. These 13
EDITs are associated with assets and liabilities that are included on the 14
Company’s rate base statement for Wyoming gas operations. Adjustment 15
J includes full normalization, non-plant rate base items and EDITs related 16
to the pension and post retirement prepaid assets the Company has 17
proposed to include in rate base in this filing. 18
Full normalization reflects plant related EDITs from the 1986 tax 19
reform and have been amortized on a straight-line basis using the South 20
Georgia amortization approach. The amortization of the non-plant and 21
pension and post retirement benefits were established upon the 22
enactment of the TCJA. The non-plant and pension and post retirement 23
18
EDITs amortization began in January 2018 and have been proposed to be 1
amortized over a 10 year time frame. 2
The deferred taxes associated with the unamortized loss on debt 3
(Adjustment E, Statement D, Schedule D-1, page 3), included on page 1 4
reflects the anticipated 2019 amortization and Adjustment J is the 5
decrease to deferred taxes to reflect the amortization of the full 6
normalization adjustment for 2019 as shown on Schedule J-2, page 5. 7
As previously discussed, Montana-Dakota is proposing to include 8
Provision for Pension Benefits (Adjustment G) and Provision for Post-9
Retirement (Adjustment H) in rate base. Both prepaid assets have an 10
associated deferred income tax liability associated and has been reflected 11
in these adjustments in Statement D, Schedule D-1, pages 5 and 6, 12
respectively. 13
These are all of the pro forma adjustments to revenue, expense 14
and rate base. 15
Q. Are you proposing changes to the Purchased Gas Cost Adjustment - 16
Rate 88? 17
A. Yes. As discussed above, Montana-Dakota has proposed to 18
include revenues from interruptible customers in the development of the 19
revenue requirement in this proceeding. As such, Subsection 6 will no 20
longer be necessary and the Company has proposed to remove this 21
section from its tariff. 22
19
Upon implementation of final rates in this Docket, the non-core 1
revenue credit will be eliminated and the Company will establish a non-2
core revenue credit balance that will be returned to firm customers. In the 3
Company’s next annual Rate 88 filing, the remaining non-core credit 4
balance will included as a component of the surcharge for firm customers 5
only. The following year, any remaining balance will be included in the 6
unrecovered purchased gas cost account. 7
Q. What is the additional revenue requirement calculated on Exhibit 8
No.__(TRJ-1)? 9
A. Exhibit No.__(TRJ-1), which is identical to Statement A, page 1, 10
shows the calculation of the revenue deficiency of $1,051,927 based on 11
the pro forma operating income and rate base and using the overall rate of 12
return of 7.754 percent from Statement E, page 1. 13
Q. Does this complete your direct testimony? 14
A. Yes, it does. 15

class cost of service study by the major rate classifications, Residential, 16
Small Firm General, Large Firm General, Small Interruptible Sales and 17
Transportation, and Large Interruptible Sales and Transportation. 18
Statement K, Schedule K-1 provides a report entitled "Cost of Service by 19
Component." This report shows the total dollars and unit cost required 20
under each rate if the Pro Forma rate of return of 7.754 percent were to be 21
earned for the demand, energy and customer cost components of each 22
rate schedule. 23
3
Statement K, Schedule K-2, is a report of the rate base, income 1
statement and Pro Forma adjustments as allocated to each rate schedule. 2
The description of the distribution plant allocators is provided in Statement 3
K, Schedule K-3. The allocation factors for each class and cost 4
component are provided in Statement K, Schedule K-4. 5
The embedded class cost of service study is based on the 6
Wyoming natural gas operations results for the 12 months ended 7
December 31, 2018 as adjusted to reflect the Pro Forma adjustments as 8
sponsored by Mr. Jacobson. 9
Q. What were the results of the embedded class cost of service study? 10
A. The overall Wyoming natural gas rate of return based on the actual 11
results for the 12 months ending December 31, 2018 adjusted for known 12
and measurable changes is 2.399 percent. The returns by customer class 13
are as shown below: 14
Customer Class ROR Residential Service 0.498 % Small Firm General Service 1.764 % Large Firm General Service 2.575 % Small Interruptible Service 40.312 % Large Interruptible Service 63.687 %
Q. How did you determine what costs should be assigned to each class 15
of customers? 16
A. The starting point was classifying the functionalized costs by 17
FERC account for all rate base and income statement items as demand, 18
energy or customer related based on the component of service being 19
4
provided. Demand-related costs are costs that vary with the demand 1
imposed by the customer, energy-related costs are costs that vary with the 2
amount of natural gas used by the customer and customer-related costs 3
are fixed costs driven by the number of customers served. 4
Next the plant, expense and revenue items that were identified as 5
directly related to a specific class of customers were directly assigned to 6
the appropriate class. Finally, the remaining costs were allocated using 7
the various allocation factors shown in Statement K, Schedule K-4, on the 8
basis of cost responsibility. 9
Q. Would you please provide an overview of the allocation process 10
including the rationale underlying the choice of allocation factors? 11
A. Yes. I will start with the plant in service items from the Gas Utility 12
Plant in Service, Statement B starting on Statement K, Schedule K-2, 13
Page 1. The allocation of distribution plant serves as the basis for 14
allocating many of the rate base items. 15
Turning now to the distribution plant investment; each distribution 16
plant account is analyzed and allocated based on the cause for the 17
investment. Distribution mains, services and meters represent 18
approximately 93 percent of the total gross distribution investment and 19
therefore the allocation of these three accounts drives the allocation of the 20
remaining distribution investment. The investment in distribution mains 21
has been assigned 75 percent to the demand component and 25 percent 22
to the customer component. The amount classified as demand related 23
was allocated to each rate class based on the design day demand 24
5
attributed to each class and the amount classified as customer related 1
was allocated to each rate class based on the average number of 2
customers in each rate class. The investment in services, service 3
regulators and meters is related solely to a customer connection and 4
therefore classified as customer related. Service regulators and meters 5
were allocated to the rate classes based on Factor 10 which represents a 6
meter weight for each customer class. The meter weights were derived by 7
comparing the installed cost per meter for each rate class to the cost 8
necessary to serve residential customers with the residential class 9
weighted as one. A description of the distribution plant allocators is 10
provided in Statement K, Schedule K-3. 11
The allocation of the remainder of the rate base items is self-12
explanatory with the allocation factor noted for each line item. 13
Q. Can you elaborate on why the investment in distribution mains was 14
assigned 75 percent to the demand component and 25 percent to the 15
customer component? 16
A. If all customer classes had equal but minimal gas service needs, 17
the Company would install a system comprised of only two-inch mains. 18
Seeing that two-inch mains would be the minimal size of a system, it is 19
appropriate to assign a portion of the main costs to the customer 20
component to reflect the system design the Company would employ if all 21
customers were to use little or no gas. To reflect customer needs, or 22
demands on the system, the Company installs larger mains when 23
6
customers use more gas than can be served from a two-inch main 1
system. 2
To estimate the portion of the mains balance that is customer-3
related the Company utilizes the minimum system method. In general 4
terms, the approach calls for the analyst to compute the cost of the 5
distribution system’s total footage utilizing the average book cost of the 6
minimum sized pipe commonly in use (two-inch mains) and compare this 7
amount to the actual mains plant balance. The cost of the minimum 8
system divided into the actual mains plant balance is thought to be the 9
approximate customer-related component, with the remainder being 10
demand-related. 11
The Company’s financial data at the level of detail required is 12
limited to the mains with a vintage of 1995 or later so the minimum system 13
study was performed using only that data. The data available reflects 14
approximately 41% of the total footage of mains and approximately 65% of 15
the plant balance. The results of the study indicate the customer 16
component of the mains plant is approximately 70%. However, the 17
Company is proposing to maintain its conservative 25% allocation to the 18
customer component and 75% to the demand component for this 19
proceeding. 20
Q. Would you please continue your discussion of the embedded class 21
cost of service study with an explanation of the income statement 22
items in the study? 23
7
A. The allocation of the income statement items starts on Statement 1
K, Schedule K-2, Pages 2, 10, and 18 for the Residential, Firm General, 2
and Interruptible classes, respectively, with the allocation of revenues. As 3
shown, sales and transportation service revenues are directly assigned 4
based on the revenues produced by each rate class. The other revenues 5
are allocated based on the source of the revenue item. Each item is 6
shown along with the allocation factor applied. 7
Operation and maintenance expenses consisting of cost of 8
purchased gas, production, distribution customer accounts, customer 9
service and information, sales and administrative and general expenses 10
are shown starting in Statement K, Schedule K-2, Pages 3, 11, and 19 for 11
the Residential, Firm General, and Interruptible classes, respectively. The 12
cost of purchased gas is directly assigned to each class based on the gas 13
costs included in the Pro Forma revenues. The cost of purchased gas is 14
recovered through the gas cost tracking adjustment and is not recovered 15
through the rates that will be established in this rate case. The remaining 16
operation and maintenance expenses are allocated based on cost 17
causation and typically follow the plant investment previously described in 18
the rate base section. The remainder of the income statement reflects the 19
allocation of depreciation expense, taxes other than income and income 20
taxes as denoted by each line item. Finally, the Pro Forma adjustments 21
are set forth in the Overall Cost of Service section, Statement K, Schedule 22
K-2, Pages 5, 13, and 21 for the Residential, Firm General, and 23
Interruptible classes, respectively. The Pro Forma allocation factors begin 24
8
on Pages 2, 5, and 8 of Statement K, Schedule K-4 for the Residential, 1
Firm General, and Interruptible classes, respectively. The allocation of 2
costs to each rate schedule is presented in the same format as described 3
above for Residential Rate 60. 4
Q. For what purpose has the embedded class cost of service study 5
been used? 6
A. The study results have been used to guide the allocation of the 7
revenue requirement to the various classes as well as the rate designs 8
applicable to each customer class. 9
Q. What methodology did you use to apportion the proposed rate 10
increase among the customer classes? 11
A. As discussed in Ms. Kivisto’s testimony, the core/non-core revenue 12
allocation process authorized in Docket No. 30013-GR-93-47 is proposed 13
to be discontinued in this proceeding. Accordingly, costs were assigned to 14
the interruptible sales and transportation classes in the same manner as 15
the firm classes. 16
I used the embedded class cost study as a guide to allocating the 17
revenue deficiency to the various customer classes. The revenue 18
increase necessary to bring the classes to the overall rate of return ranges 19
from an increase of approximately 10.9 percent for Residential Rate 60 to 20
a reduction of 62.1 percent for Large Interruptible Rate 82. In allocating 21
the revenue increase I first considered the rates of return each class is 22
achieving, as well as the required increases or decreases necessary to 23
move rates to cost of service. The magnitude of the decreases required 24
9
for the interruptible class rates to be based solely on the cost to serve is 1
too substantial and therefore and unreasonable proposition in this case. 2
However, my goal with the allocation of the increase is still to move in that 3
direction. 4
With the overall increase in revenues at 6.96% I wanted to ensure 5
the interruptible classes received a moderate decrease while keeping the 6
impact to the firm classes reasonable in nature and not excessively out of 7
line with the overall increase. This balance was struck by moving the 8
small and large firm classes to cost of service rates while giving the 9
interruptible classes 5% of their respective decreases and allowing the 10
remainder of the increase to the residential class. 11
Q. What is the percentage of the proposed increase by class of 12
customer? 13
A. The proposed increase to each of the classes is shown in the table 14
below: 15
Class Increase Residential 8.41 % Small Firm General 7.76 % Large Firm General 4.32 % Small Interruptible -1.03 % Large Interruptible -3.06 % Overall 6.96 %
16
The greatest increase, 8.4 percent for Residential, is approximately 17
1.2 times the overall increase and compares to the 1.6 times that would be 18
required to achieve cost of service rates for the class. 19
10
Q. What is the total revenue effect of the proposed changes to the 1
Company’s natural gas distribution rates? 2
A. The proposed rates will produce additional revenues of $1,052,167 3
or 6.96 percent annually based on the Pro Forma 2018 throughput. This 4
is different than the revenue deficiency presented in Mr. Jacobson’s 5
testimony due to rounding occurring in the revenue allocation process. 6
Exhibit No. __ (JRH-1) represents a summary of the proposed revenue 7
increase to the firm service customers. The exhibit shows the rate number 8
and a description along with the revenues calculated under the present 9
and proposed rates. The amount and percentage increase is also shown 10
for the proposed revenue increase. 11
Q. Would you please explain Exhibit No. ____(JRH-2)? 12
A. Yes. Exhibit No. ____ (JRH-2) depicts bill comparisons based on 13
typical monthly consumption levels for an annual period for Residential 14
and Firm General Service customers. As shown by the comparisons, the 15
proposed rate structure will result in an average increase, based on final 16
proposed rates, of approximately $3.94 per month for the typical 17
Residential customer using 88 dk on an annual basis. A Small Firm 18
General Service customer (Rate 70 with a meter rated less than 500 cubic 19
feet per hour) would see an increase of approximately $5.59 per month 20
and a Large General Service customer (Rate 70 with a meter rated 500 21
cubic feet per hour or more) would see an increase of approximately 22
$20.59 per month. 23
11
Q. What were the objectives underlying the allocation of the increase 1
and the rates proposed to recover the revenue requirement? 2
A. The embedded class cost of service study and proposed revenue 3
allocation embody several of the recognized ratemaking objectives by 4
their effectiveness in yielding the total revenue requirement under the fair-5
return standard, fairness of the specific rates in the apportionment of the 6
total costs of service among the different consumers, and efficiency of the 7
rate classes. The rate forms proposed also recognize a balanced and 8
gradual move toward meeting the objectives noted above to be cognizant 9
of the rate stability objective. To capture that balance, the proposed rates 10
reflect a move toward cost-based rates but not the full step necessary to 11
price each service to reflect the specific embedded cost components. 12
Q. How are you proposing to collect the allocated increase from each of 13
the rate classes? 14
A. First, I am proposing increases to the Basic Service Charges for the 15
Residential class. The Basic Service Charge under Residential Rate 60 is 16
proposed at $0.64 per day which reflects an average monthly charge of 17
$19.46, an increase of $3.65 per month from the currently effective charge 18
based on the customer related costs identified in the Embedded Class 19
Cost of Service Study provided in Statement K. The Company is not 20
proposing an increase to any of the remaining customer classes. 21
After taking into account any revenue increase associated with the 22
changes in the Basic Service Charge, the remaining increase in revenues 23
is proposed to be reflected through the Distribution Delivery Charge 24
12
components for the Residential class. The entire increase or decrease in 1
revenues assigned to the other rate classes was assigned to the 2
Distribution Deliver Charge. 3
The rate design calculations supporting the final rate levels are 4
included in Statement L, Pages 3-6. A representation of the annual billing 5
impact for the Residential and Firm General Service classes is provided 6
on Pages 7-9 of Statement L. 7
Q. Would you please explain the rationale increasing the Residential 8
Basic Service Charge? 9
A. Aligning fixed and variable rates with the costs they are intended to 10
recover will lead to better and more efficient outcomes for both the 11
Company and its customers by: 12
1. Reducing the volatility in the Company’s revenues due to 13
extreme weather or economic conditions; 14
2. Creating more stable customer bills and sensible price signals 15
for customers seeking to invest in energy efficiency, energy conservation 16
measures or distributed generation; and 17
3. Reducing the cross-subsidies within the class. 18
By increasing the Basic Service Charge the Company is less dependent 19
on sales to recover its fixed costs. Higher fixed charges can reduce the 20
need for frequent rate increases caused by reduced sales, create a more 21
stable customer bill and align rates with costs. 22
Q. Does this conclude your direct testimony? 23
A. Yes, it does. 24

Before the Wyoming Public Service Commission
Docket No. 30013-351-GR-19
Direct Testimony of
Stephanie Bosch
Q. Would you please state your name and business address? 1
A. My name is Stephanie Bosch and my business address is 400 2
North Fourth Street, Bismarck, North Dakota 58501. 3
Q. What is your position with Montana-Dakota Utilities Co.? 4
A. I am the Regulatory Affairs Manager for Montana-Dakota Utilities 5
Co. (Montana-Dakota). 6
Q. Would you please describe your duties as Regulatory Affairs 7
Manager? 8
A. I am responsible for the proper application of the Company’s gas 9
and electric rates in the Customer Care and Billing System (CC&B), the 10
application of tariffs and the preparation of miscellaneous rate filings. 11
Q. Would you please describe your education and professional 12
background? 13
A. I graduated from the University of North Dakota in 1995 with a 14
Bachelor of Business and Public Administration degree in Banking and 15
Financial Economics. I joined Montana-Dakota in June 1997 as a Rate 16
Clerk in the Regulatory Affairs area and realized positions of increasing 17
responsibility within the Regulatory Affairs Department until 2011 when I 18
2
left the Company. In 2013 I returned to the Company as a Regulatory 1
Analyst before attaining my current position in August of 2015. 2
Q. Have you testified in other proceedings before regulatory bodies? 3
A. Yes. I have previously presented testimony before this Commission 4
and the Public Service Commissions of Montana and North Dakota. 5
Q. What is the purpose of your testimony in this proceeding? 6
A. The purpose of my testimony is present the gas revenues at current 7
rates included in Statement F Schedules F-2 and F-3 of this Application 8
and the changes proposed to the Company’s tariffs provided in Appendix 9
B. 10
Q. What statements and exhibits are you sponsoring in this 11
proceeding? 12
A. I am sponsoring Statement F Schedules F-2 and F-3 and the 13
proposed rate schedules provided in Appendix B to the Application, with 14
the exception of the proposed change to the Purchased Gas Cost 15
Adjustment (PGA) Rate 88 tariff, which is sponsored by Mr. Jacobson. 16
Q. Would you please explain the calculation of revenue at current rates 17
included in Statement F Schedules F-2 and F-3? 18
A. Yes. The Company applied the Basic Service Charges and 19
Distribution Delivery Charges (including the current non-core credit rate) 20
applicable under each rate schedule, and as authorized in Docket No. 21
30013-297-GR-14, to an annualized level of customers and volumes. 22
Interruptible sales and transportation customers were priced at the 23
3
applicable rate schedules’ maximum rate per Dk, unless service is being 1
provided for under a contract rate. The PGA rates are reflective of the 2
March 2019 PGA rates, excluding the current surcharge. 3
Q. Would you please describe changes the Company is proposing to its 4
gas tariffs? 5
A. Yes. The Company is proposing the following changes to the gas 6
tariffs as clearly identified in the legislative copy of the tariffs provided in 7
Appendix B of this Application: 8
• The rates described by Mr. Hatzenbuhler have been incorporated 9
into the proposed tariffs. 10
• Remove the “core” and “non-core” designations included in select 11
rate schedules’ titles. 12
• Revise the Metering Requirements provisions under the 13
Company’s Interruptible Gas Sales Rates 71 and 85 tariffs to 14
recognize that, while most customers are located within the 15
Company’s fixed network system used for meter reading and 16
therefore additional equipment is not needed for their meter data, 17
select customers may still be required to install additional 18
equipment for the transmission of such meter data if located 19
outside the Company’s fixed network communication system. 20
• Clarify the charges included in the determination of a penalty 21
payment as provided for under the Penalty for Failure to Curtail or 22
Interrupt provisions applicable under the Company’s Interruptible 23
4
Gas Sales Rates 71 and 85 and Transportation Rates 81 and 82 1
tariffs. The proposed change clarifies that all charges billed under 2
Rate 70, with the exception of the Basic Service Charge, would be 3
billed a customer in the event of a penalty situation. 4
• Revise the following provisions included in the Conditions of 5
Service Rate 100 tariff to: 6
o Revise the non-residential reconnection fee for seasonal or 7
temporary customers to reduce the seasonal reconnection 8
fee for distribution revenues collected while the customer 9
was in-service for usage above the respective class’ 10
average annual authorized use. 11
o Remove the word “written” from Paragraph 20h 12
(Reconnection after Nonpayment) of the General Terms 13
and Conditions section of Rate 100. The proposed change 14
eliminates the need to have a payment arrangement be in 15
written form. 16
• Other minor wording changes are included throughout the 17
Company’s tariffs to improve the readability of the rate without 18
modifying any conditions. These changes are clearly denoted on 19
the tariff sheets in the legislative format. 20
Q. Is the Company proposing any changes to the Company’s Extension 21
Policies Rate 119 and 120? 22
5
A. Yes. The Company is proposing to update the Levelized Annual 1
Revenue Requirement (LARR) Factor identified on the tariff to reflect the 2
costs and return included in this case. 3
The Company is also proposing to clarify that the cost of the 4
extension shall include all costs from the main, if applicable, up to, and 5
including the riser. All costs after the riser will not be included in the cost 6
of the extension. 7
Q. Does this conclude your testimony? 8
A. Yes. 9
