Falls Water Co., Inc.
INTRODUCTION 1
Q. Please state your name and business address. 2
A. My name is Harold Walker, III. My business address is 1010 Adams Avenue, 3
Audubon, Pennsylvania 19403. 4
Q. By whom are you employed and in what capacity? 5
A. I am employed by Gannett Fleming Valuation and Rate Consultants, LLC as 6
Manager, Financial Studies. 7
Q. What is your educational background and employment experience? 8
A. My educational background, business experience and qualifications are provided 9
in Appendix A. 10
SCOPE OF TESTIMONY 11
Q. What is the purpose of your testimony? 12
A. The purpose of my testimony is to recommend an appropriate overall rate of return 13
that Falls Water Co., Inc. (“Falls Water” or the “Company”) should be afforded an 14
opportunity to earn on its water service rate base. My testimony is supported by 15
Exhibit No. 6, which is composed of 19 Schedules. 16
SUMMARY OF RECOMMENDATION 17
Q. What is your recommended cost of equity? 18
A. My recommendation is that Falls Water be permitted an overall rate of return of 19
8.12%, including an 11.00% cost of common equity, based upon the Company’s 20
hypothetical capital structure at December 31, 2022. My recommended cost of 21
common equity reflects Falls Water’s unique risk characteristics. 22
WALKER, Di 2
Falls Water Co., Inc.
Q. How did you determine your recommended common equity cost rate? 1
A. I used several models to help me in formulating my recommended common equity 2
cost rate including Discounted Cash Flow (“DCF”), Capital Asset Pricing Model 3
(“CAPM”) and Risk Premium (“RP”). 4
Q. Is it important to use more than one market model? 5
A. Yes. It is necessary to estimate common equity cost rates using a number of 6
different models. At any given time, a particular model may understate or overstate 7
the cost of equity. While any single investor may rely solely upon one model, 8
different investors rely on different models and many investors use multiple 9
models. Therefore, because the price of common stock reflects a number of 10
valuation models, it is appropriate to estimate the market-required common equity 11
cost rate by applying a broad range of analytical models. 12
Q. Please summarize your common equity cost rate recommendation. 13
A. There is no market data concerning Falls Water’s shares of common stock because 14
Falls Water shares of common stock are not publicly traded. Accordingly, due to 15
the lack of market data concerning Falls Water’s equity, I used a comparable group 16
of publicly traded companies to estimate the common equity cost rate. Based upon 17
the results of my entire analysis, I conclude Falls Water’s current common equity 18
cost rate is at least 11.00%. The current range of common equity cost for Falls 19
Water is 9.70% (DCF), 12.30% (CAPM), and 11.20% (RP). Value Line Investment 20
Survey (“Value Line”) is relied upon by many investors and is the only investment 21
advisory service of which I am aware that projects earned return on equity. As a 22
check on the reasonableness of my common equity cost rate recommendation, I 23
WALKER, Di 3
Falls Water Co., Inc.
reviewed Value Line’s projected returns on common equity for comparable 1
utilities. Value Line’s projected earned returns on common equity for my 2
comparable utilities average 10.7% for the period 2025-2027. For 2021, the 3
comparable utilities earned a return on common equity of 11.3% and earned a return 4
on common equity of 10.5% in 2020. The range of the projected returns and actual 5
returns suggests that my recommendation that Falls Water be permitted an 6
opportunity to earn 11.00% is reasonable, if not conservative. 7
Q. What ROE is the Company requesting? 8
A. As stated in the testimony of Adam Rue, the Company is requesting no change to 9
their currently authorized ROE of 10.2%. 10
PRINCIPLES OF RATE REGULATION AND FAIR RATE OF RETURN 11
Q. What are the principles guiding fair rates of return in the context of rate 12
regulation? 13
A. In a capitalistic or free market system, competition determines the price for all 14
goods and services. Utilities are permitted to operate as monopolies or near 15
monopolies as a tradeoff for a ceiling on the price of service because: (1) the 16
services provided by utilities are considered necessities by society; and (2) capital-17
intensive and long-lived facilities are necessary to provide utility service. 18
Generally, utilities are required to serve all customers in their service territory at 19
reasonable rates determined by regulators. As a result, regulators act as a substitute 20
for a competitive-free market system when they authorize prices for utility service. 21
Although utilities operate in varying degrees as regulated monopolies, they 22
must compete with governmental bodies, non-regulated industries, and other 23
WALKER, Di 4
Falls Water Co., Inc.
utilities for labor, materials, and capital. Capital is provided by investors who seek 1
the highest return commensurate with the perceived level of risk; the greater the 2
perceived risk, the higher the required return rate. In order for utilities to attract the 3
capital required to provide service, a fair rate of return should equal an investor-4
required, market-determined rate of return. 5
Q. What constitutes a fair rate of return? 6
A. Two noted Supreme Court cases define the benchmarks of a fair rate of return. In 7
Bluefield1, a fair rate of return is defined as: (1) equal to the return on investments 8
in other business undertakings with the same level of risks (the comparable earnings 9
standard); (2) sufficient to assure confidence in the financial soundness of a utility 10
(the financial integrity standard); (3) adequate to permit a public utility to maintain 11
and support its credit, enabling the utility to raise or attract additional capital 12
necessary to provide reliable service (the capital attraction standard). The second 13
case, Hope2, determined a fair rate of return to be based upon guidelines found in 14
Bluefield as well as stating that: (1) allowed revenues must cover capital costs 15
including service on debt and dividends on stock; and (2) the Commission was not 16
bound to use any single formula or combination of formulae in determining rates. 17
Utilities are not entitled to a guaranteed return. However, the regulatory-18
determined price for service must allow the utility a fair opportunity to recover all 19
costs associated with providing the service, including a fair rate of return. 20

WALKER, Di 5
Falls Water Co., Inc.
INVESTMENT RISK 1
Q. Previously, you referred to risk. Please define the term risk. 2
A. Risk is the uncertainty associated with a particular action; the greater the 3
uncertainty of a particular outcome, the greater the risk. Investors who invest in 4
risky assets expose themselves to investment risk particular to that investment. 5
Investment risk is the sum of business risk and financial risk. Business risk is the 6
risk inherent in the operations of a business. Assuming that a Company is financed 7
with 100% common equity, business risk includes all operating factors that affect 8
the probability of receiving expected future income such as: sales volatility, 9
management actions, availability of product substitutes, technological 10
obsolescence, regulation, raw materials, labor, size and growth of the market 11
served, diversity of the customer base, economic activity of the area served, and 12
other similar factors. 13
Q. What is financial risk? 14
A. Financial risk reflects the manner in which an enterprise is financed. Financial risk 15
arises from the use of fixed cost capital (leverage) such as debt and/or preferred 16
stock, because of the contractual obligations associated with the use of such capital. 17
Because the fixed contractual obligations must be serviced before earnings are 18
available for common stockholders, the introduction of leverage increases the 19
potential volatility of the earnings available for common shareholders and therefore 20
increases common shareholder risks. 21
Although financial risk and business risk are separate and distinct, they are 22
interrelated. In order for a company to maintain a given level of investment risk, 23
WALKER, Di 6
Falls Water Co., Inc.
business risk and financial risk should complement one another to the extent 1
possible. For example, two firms may have similar investment risks while having 2
different levels of business risk, if the business risk differences are compensated 3
for by using more or less leverage (financial risk) thereby resulting in similar 4
investment risk. 5
DESCRIPTION OF FALLS WATER 6
Q. Please give a brief description of the Company. 7
A. Falls Water is a private or investor-owned company. Falls Water is a regulated 8
public utility that provides water service to about 7,000 (as of December 31, 2022) 9
customers located in its franchise territories in Bonneville County and Jefferson 10
County, Idaho. The price and conditions of service of Falls Water is regulated by 11
the Idaho Public Utilities Commission (“Commission” or “PUC”). 12
Falls Water is a wholly-owned subsidiary of NW Natural Water of Idaho, 13
LLC. NW Natural Water of Idaho, LLC is the sole direct source of Falls Water’s 14
external equity capital. In addition to Falls Water, NW Natural Water of Idaho, 15
LLC also owns Gem State Water Company, LLC (regulated utility) and Gem State 16
Infrastructure, LLC (unregulated). NW Natural Water of Idaho, LLC is a wholly-17
owned subsidiary of NW Natural Water, LLC. NW Natural Water, LLC owns 18
water and wastewater utility companies which are located in five states throughout 19
the United States (e.g., Falls Water). NW Natural Water, LLC is a subsidiary of 20
Northwest Natural Holding Company. 21
Northwest Natural Holding Company, through its subsidiaries, provides 22
regulated natural gas distribution and gas transportation services in two states, gas 23
WALKER, Di 7
Falls Water Co., Inc.
storage facilities, natural gas asset management services, operates an appliance 1
retail center, water and wastewater utility services in five states, non-regulated 2
renewable natural gas, and other investment businesses. 3
THE INDUSTRY 4
Q. Please give a brief overview of the industry in which the Company operates. 5
A. Falls Water operates in the water supply industry. The water supply industry has a 6
Standard Industrial Classification (“SIC”) code of 4941, has water utilities, and 7
includes establishments primarily engaged in distributing water for sale for 8
residential, commercial, and industrial uses. Government controlled 9
establishments such as municipalities, public service districts and other local 10
governmental entities dominate the industry. Private companies or investor owned 11
utilities (“IOU”) are active in the construction and improvement of water supply 12
facilities and infrastructure. There are currently about 11,000 U.S. Businesses with 13
a SIC code of 4941. 14
A comparative industry to the water supply industry is the wastewater 15
supply industry. The wastewater utility industry has a Standard Industrial 16
Classification (“SIC”) code of 4952 (Sewerage Systems), has sewer utilities, and 17
includes establishments primarily engaged in the collection and disposal of wastes 18
conducted through a sewer system, including such treatment processes as may be 19
provided. There are currently about 2,200 U.S. Businesses with a SIC code of 4952. 20
The water supply industry is the most fragmented of the major utility 21
industries with more than 53,000 community water systems in the U.S. (83% of 22
which serve less than 3,300 customers). The nation’s water systems range in size 23
WALKER, Di 8
Falls Water Co., Inc.
from large municipally owned systems, such as the New York City water system 1
that serves approximately 9 million people, to small systems, where a few 2
customers share a common well. 3
According to the U.S. Environmental Protection Agency’s (“EPA”) most 4
recent survey of publicly-owned wastewater treatment facilities in 2008, there are 5
approximately 15,000 such facilities in the nation, serving approximately 74% of 6
the U.S. population. Ninety eight percent of domestic wastewater systems are 7
government owned rather than IOUs. Currently, there are no wastewater utility 8
companies that have actively traded stock.3 9
An estimated 16% of all water supplies are managed or owned by IOUs. 10
IOUs consist of companies with common stock that is either actively traded or 11
inactively traded, as well as companies that are closely held, or not publicly traded. 12
Currently, there are only about nine investor owned water utility companies with 13
publicly traded stock in the U.S. 14
The water utility industry’s and wastewater utility industry’s increased 15
compliance with state and federal water purity levels and large infrastructure 16
replacements are driving consolidation of the wastewater utility and water utility 17
industries. Because many wastewater utility and water utility operations do not 18
have the means to finance the significant capital expenditures needed to comply 19
with these requirements, many have been selling their operations to larger, 20
financially stronger utilities. 21
3Many of the publicly traded water utility stocks also own some wastewater utilities but there are no
publicly traded utility stocks which are comprised solely of wastewater utilities.
WALKER, Di 9
Falls Water Co., Inc.
The larger IOUs have been following an aggressive acquisition program to 1
expand their operations by acquiring smaller wastewater and water systems. 2
Generally, they enter a new market by acquiring one or several wastewater or water 3
utilities. After their initial entry into a new market, the larger investor-owned water 4
utility companies continually seek to expand their market share and services 5
through the acquisition of wastewater and water utility businesses and operations 6
that can be integrated with their existing operations. Such acquisitions may allow 7
a company to expand market share and increase asset utilization by eliminating 8
duplicate management, administrative, and operational functions. Acquisitions of 9
small, independent utilities can often add earning assets without necessarily 10
incurring the costs associated with the SDWA if such acquisitions are contiguous 11
to the potential purchaser. 12
In summary, the result of increased capital spending, to meet the SDWA 13
and CWA requirements4 and replace the aging infrastructure of many systems, has 14
moved the wastewater and water industries toward consolidation. Moreover, 15
Federal and State regulations and controls concerning water quality are still in the 16
process of being developed and it is not possible to predict the scope or the 17
enforceability of regulations or standards which may be established in the future, 18
or the cost and effect of existing and potential regulations and legislation upon Falls 19
4The SDWA, or Safe Drinking Water Act, is the principal federal law in the United States intended to
ensure safe drinking water for the public. Pursuant to the act, the EPA is required to set standards for
drinking water quality and oversee all states, localities, and water suppliers who implement these standards.
The CWA, or Clean Water Act, is the primary federal law in the United States governing water pollution.
The CWA’s objective is to restore and maintain the chemical, physical, and biological integrity of the
nation’s waters by preventing point and nonpoint pollution sources, providing assistance to publicly owned
treatment works for the improvement of wastewater treatment, and maintaining the integrity of wetlands.

Water. However, as a smaller water system, Falls Water faces the cost of 1
compliance with less financial resources when compared to larger IOU water 2
utilities. 3
COMPARABLE GROUP 4
Q. How do you estimate the cost of common equity for Falls Water? 5
A. Falls Water’s common stock is not publicly traded. Accordingly, I employed a 6
comparable group of utility companies with actively traded stock, to determine a 7
market-required cost rate of common equity capital for Falls Water. Since no 8
companies are perfectly identical to Falls Water, it is reasonable to determine the 9
market-required cost rate for a comparable group of utility companies and adjust, 10
to the extent necessary, for investment risk differences between Falls Water and the 11
comparable group. 12
Q. How did you select the comparable group used to determine the cost of 13
common equity for Falls Water? 14
A. I selected a comparable group of water utilities to determine the cost of common 15
equity for Falls Water considering security analysts’ coverage. Unlike the other 16
utility industries, only a portion of the IOU water companies with publicly traded 17
stock in the U.S. are followed by security analysts. Coverage by security analysts 18
is important when determining a market required cost of common equity. 19
Accordingly, security analysts’ coverage was considered when selecting my 20
comparable group. I selected my water utility comparable group, Water Group 21
Followed by Analysts (“Water Group”), based upon a general criteria that includes: 22
(1) all U.S. water utilities that are covered by security analysts as measured by the 23
WALKER, Di 11
Falls Water Co., Inc.
existence of sources of published projected five-year growth rates in earnings per 1
share (“EPS”); (2) with a Standard Industrial Classification (SIC) of 4941 (i.e., 2
Water Supply Facilities and Infrastructure); (3) with a North American Industry 3
Classification System (NAICS) of 221310 (i.e., Water Supply and Irrigation 4
Systems); (4) are not the announced subject of an acquisition; (5) currently pay a 5
common dividend and have not reduced their common dividend within the past four 6
years; (6) have market value of common stock, the product of multiplying the 7
closing stock price by the number of common shares outstanding, greater than 8
$500.0 million; and (7) have a total enterprise, the sum of market value, preferred 9
stock and total debt, greater than $700.0 million. 10
It should be noted that the Water Group is also referred to as the Comparable 11
Group and/or the Comparable Companies.5 The names of the utilities that comprise 12
the Comparable Group and their bond or credit ratings are listed in Table 1. 13
5All of the Comparable Companies also provide some wastewater service.

Table 1 1
Q. Why did you include not being the subject of an acquisition as a criteria for 2
the Water Group? 3
A. To begin with, there are only about nine investor owned water utility companies 4
with publicly traded stock in the U.S., and some of these companies are very small. 5
As stated previously, the IOU water industry receives only limited exposure on 6
Wall Street. 7
Additionally, merger activity in the water industry can result in abnormal or 8
“tainted” stock prices in terms of a DCF analysis because premiums are typically 9
paid in corporate acquisitions. That is, when a tender offer is made for the purchase 10
of all the outstanding stock of a company, the amount of that offer usually exceeds 11
the price at which the stock was previously traded in the market. These large 12
WALKER, Di 13
Falls Water Co., Inc.
premiums are often reflected in the prices of other water utilities that are not 1
currently the announced subject of an acquisition.6 2
CAPITAL STRUCTURE 3
Q. What is required to develop an overall rate of return? 4
A. The first step in developing an overall rate of return is the selection of capital 5
structure ratios to be employed. Next, the cost rate for each capital component is 6
determined. The overall rate of return is the product of weighting each capital 7
component by its respective capital cost rate. This procedure results in Falls 8
Water’s overall rate of return being weighted proportionately to the amount of 9
capital and cost of capital of each type of capital. 10
Q. Is there a set of regulatory and financial principles used in deciding the 11
appropriate capital structure to use for cost of capital purposes? 12
A. Yes. There is a general set of regulatory and financial principles used in deciding 13
the capital structure issue for cost of capital purposes that are consistent with both 14
regulatory and financial theories: 15
1) It is generally preferable to use a utility’s actual capital structure in 16
developing its rate of return. However, in deciding whether a departure 17
from this general preference is warranted in a particular case, it is 18
appropriate to first look to the issue of whether the utility is a financially 19
independent entity. In determining whether a utility is a financially 20
6 Multiple publications mention these impacts including Research Magazine – April 2010, Barron’s – March
2001, Utility Business – June 2002, and Value Line Investment Survey – April 2013.
WALKER, Di 14
Falls Water Co., Inc.
independent entity or self-financing, it is important to look to whether the 1
utility: 2
● has its own bond rating; 3
● provides its own debt financing; and 4
● debt financing is not guaranteed by a parent company. 5
2) When a utility issues its own debt that is not guaranteed by the public or 6
private parent and has its own bond rating, regulatory and financial 7
principles indicate to use a utility’s own capital structure, unless the utility’s 8
capital structure is not representative of the utility’s risk profile or where 9
use of the actual capital structure would create atypical results. Regulatory 10
and financial principles involve determining whether the actual capital 11
structure is atypical when compared with the capital structures approved by 12
the Commission for other utilities that operate in the same industry (i.e., 13
water utility, gas distribution utility, etc.), as well as those of the proxy 14
utility companies that operate in the same industry. 15
3) For utility subsidiaries without publicly traded stock, the manner in which 16
the utility obtains its debt financing determines whether it does its own 17
financing. Public Utility Commissions generally determine if a subsidiary 18
has financial, operational, and managerial relationships with its parent 19
entity. However, having such ties typically has not led to use of a parent’s 20
capital structure for regulatory purposes, unless the subsidiary utility issues 21
no long-term debt, issues long-term debt only to its parent, or issues long-22
term debt to outside investors only with the guarantee of its parent. 23
WALKER, Di 15
Falls Water Co., Inc.
4) If a utility does not provide its own financing, Public Utility Commissions 1
often look to another entity. Generally, Public Utility Commissions use the 2
actual capital structure of the entity that does the financing for the regulated 3
utility as long as it results in just and reasonable rates. This generally means 4
using a parent company. 5
5) If the parent’s capital structure is used, because it finances the operation of 6
the utility, regulatory and financial principles require adjustments in the 7
utility’s allowed rate of return on equity to adjust for risk differences, if any, 8
between the parent and the regulated subsidiary. If, however, the financing 9
entity’s capital structure is inconsistent relative to the capital structures of 10
the publicly-traded proxy companies used in the cost of equity analysis and 11
capital structures approved for other utilities that operate in the same 12
industry (i.e., water utility, gas distribution utility, etc.), Public Utility 13
Commissions employ a hypothetical capital structure. 14
Once the cost of equity for the proxy companies is determined, thereby 15
establishing a range of reasonable returns, Public Utility Commissions should 16
determine where to set the utility’s return in that range based upon how the utility’s 17
risk compares with that of other utilities that operate in the same industry (i.e., water 18
utility, gas distribution utility, etc.). The risk analysis begins with the assumption 19
that the utility generally falls within a broad range of average risk, absent highly 20
unusual circumstances that indicate an inconsistently high or low risk as compared 21
to other utilities that operate in the same industry (i.e., water utility, gas distribution 22
utility, etc.). Generally, financial risk is a function of the amount of debt in an 23
WALKER, Di 16
Falls Water Co., Inc.
entity’s capital structure used for cost of capital purposes. When there is more debt, 1
there is more risk. 2
Q. Does Falls Water directly raise or issue its own debt capital? 3
A. Yes, currently Falls Water has issued its own debt capital. However, prospectively, 4
Falls Water debt capital will be issued by NW Natural Water, LLC. 5
Q. What capital structure ratios are appropriate to be used to develop Falls 6
Water’s overall rate of return? 7
A. Consistent with settled rate setting principles, I believe it is necessary to evaluate 8
Falls Water’s current cost of capital based on a hypothetical capital structure at 9
December 31, 2022. Falls Water’s actual capital structure at December 31, 2022 is 10
14% debt and 86% common equity, which is not consistent with the range of capital 11
ratios used by the Comparison Group water companies. 12
Specifically, Falls Water actual 86% common equity ratio is not similar to 13
the Comparison Group’s current (September 30, 2022) common equity ratio, which 14
ranged from 40.7% to 62.1% and averaged 50.1% (see page 3 of Schedule 2). The 15
Comparison Group’s common equity ratio is relative to companies with an A credit 16
profile based on their bond ratings and have about 555-times more investor 17
provided capital (average $5.4 billion) than Falls Water ($9.8 million). The 18
significance that size plays in the market’s dictation of acceptable common equity 19
ratios can be seen by examining the size and the common equity ratios of the 20
companies which comprise the Comparison Group. 21
The amount of investor provided capital of the companies which comprise 22
Comparison Group ranges from $329.5 million to $19,047.0 million (see page 3 of 23
WALKER, Di 17
Falls Water Co., Inc.
Schedule 2). The two largest companies in the Comparison Group, or those 1
companies with more than $10,000 million of investor provided capital have 2
common equity ratios which range from 40.7% to 45.6%, while the two smallest 3
companies in the Comparison Group had common equity ratios ranging from 4
55.8% to 62.1%. The two smallest companies in the Comparison Group have 5
$329.5 million to $713.5 million of investor provided capital. Therefore, even the 6
two smallest companies in the Comparison Group are much larger than Falls Water, 7
since they have about 53-times more investor provided capital (average $521.5 8
million) than Falls Water’s $9.8 million investor provided capital. 9
Based on the aforesaid, I believe it is appropriate to evaluate Falls Water’s 10
current cost of capital based upon a targeted ratemaking capital structure which 11
contains no less than 55% common equity. A targeted ratemaking capital structure 12
of 45% debt and 55% common equity is similar to the smallest companies in the 13
Comparison Group. Further, the recommended ratios are in line with S&P’s 14
implied ratios, based upon published financial benchmarks for water utilities, and 15
accounts for some of the risk differences between Falls Water and the Comparison 16
Group. 17
Q. How does your recommended capital structure compare with ratios employed 18
by other investor-owned companies? 19
A. The capital structure I recommend for Falls Water reflects a common equity ratio 20
of 55% which is similar to the range of the ratios employed by other investor-owned 21
water companies as shown on pages 1 and 2 of Schedule 2. A comparison of my 22
WALKER, Di 18
Falls Water Co., Inc.
recommendation for Falls Water’s capital structure ratios to those recently 1
employed by the Comparison Group is shown in Table 2. 2

Falls Water’s rate making capital structure ratios are reasonable based upon 5
the above information. 6
EMBEDDED COST RATE 7
Q. What embedded cost rates do you recommend be used to calculate Falls 8
Water’s overall rate of return? 9
A. Consistent with my recommended capital structure ratios I recommend using an 10
embedded debt cost rate of 4.61% for Falls Water as reflected in Schedule 1. The 11
4.61% embedded debt cost rate is a weighted cost rate comprised of Falls Water’s 12
actual embedded debt cost rate, 2.80%, and a 5.40%7 cost rate for the additional 13
7 Based upon the settled yields implied in the Treasury Bond future contracts and the long-term and recent
trends in spreads between long-term government bonds and A-rated public utility bonds available to me at
the time Schedule 11 was prepared, I conclude that the market believes that if the Comparable Companies
issued new long-term bonds near term it would be priced to yield about 5.4% based upon their credit profile
of A.

FINANCIAL ANALYSIS 3
Q. Have you reviewed historical financial information of Falls Water as part of 4
your analysis? 5
A. Yes. On page 1 of Schedule 3, I developed a five-year analysis, ending in 2021, 6
detailing various financial ratios for Falls Water. On Schedule 4, I performed a 7
similar five-year analysis for the Water Group. Schedule 5 reveals the results of 8
operations for a large broad-based group of utilities known as the Standard & Poor’s 9
(“S&P”) Utilities for the five years ending 2021. This information is useful in 10
determining relative risk differences between different types of utilities. 11
Comparing Falls Water, the Comparable Group and the S&P Utilities’ 12
coverage of fixed charges and the various cash flow coverage proves that the 13
Comparable Group has experienced a higher level of coverage than the S&P 14
Utilities. Reviewing Falls Water’s various cash flow coverages shows Falls Water 15
has had higher levels of coverage than the Comparable Group.8 16
Q. What do you conclude from the comparison of all the information shown on 17
Schedules 3 through 5? 18
A. Taken together, these comparisons show that Falls Water is exposed to risk that is 19
similar in nature but greater in degree compared with the Comparable Groups. This 20
is evident in particular when one considers the size and diversification of Falls 21

74.1% to 89.7% during the years analyzed.

Water, or lack thereof, as compared to the Comparable Companies. Moreover, the 1
evidence from the various financial ratios shows Falls Water’s risks as being similar 2
to the Comparable Companies’ but less than the larger S&P Utilities. 3
Q. What information is shown on Schedule 6? 4
A. Schedule 6 lists the names, issuer credit ratings, common stock rankings, betas and 5
market values of the companies contained in the Comparable Group and the S&P 6
Utilities. As is evident from the information shown on Table 3, the Comparable 7
Group and the S&P Utilities are similar to each other in risk. 8

Water Group A High (A) 0.79 3,138.126 Mid-Cap
S&P Utilities BBB+ Average (B+) 0.88 25,329.726 Large-Cap
Table 3 9
The Water Group’s average issuer credit ratings and common stock 10
rankings are higher than the S&P Utilities. The average beta of the Comparable 11
Group, 0.79, is less than the average beta of the S&P Utilities, 0.88. Beta is a 12
measure of volatility or market risk; the higher the beta, the higher the market risk. 13
The market values provide an indication of the relative size of each group. As a 14
generalization, the smaller the average sizes of a group, the greater the risk. 15
Page 2 of Schedule 6 shows that Falls Water has generally experienced the 16
lowest return on equity (“ROE”) when compared to the Comparable Companies. 17
WALKER, Di 21
Falls Water Co., Inc.
Further, Falls Water’s dividend payout ratio is lower than the Comparable 1
Companies’ dividend payout ratio. 2
S&P, the predominant bond rating agency, considers profit to be a 3
fundamental determinant of credit protection. S&P states that a firm’s profit level: 4
Whether generated by the regulated or deregulated side of the 5
business, profitability is critical for utilities because of the need to 6
fund investment-generating capacity, maintain access to external 7
debt and equity capital, and make acquisitions. Profit potential and 8
stability is a critical determinant of credit protection. A company 9
that generates higher operating margins and returns on capital also 10
has a greater ability to fund growth internally, attract capital 11
externally, and withstand business adversity. Earnings power 12
ultimately attests to the value of the company’s assets, as well. In 13
fact, a company’s profit performance offers a litmus test of its 14
fundamental health and competitive position. 15
16
Accordingly, the conclusions about profitability should confirm the 17
assessment of business risk, including the degree of advantage 18
provided by the regulatory environment.9 19
Q. What information is shown on Schedule 7? 20
A. Schedule 7 reveals the capital intensity and capital recovery for Falls Water, the 21
Comparable Companies and the S&P Utilities. Based upon the 2021 capital 22
intensity ratio of plant to revenues, Falls Water ($3.91) is less capital intensive as 23
compared to the Water Group ($6.60) and more than the S&P Utilities ($4.78). 24
From a purely financial point of view, based on current accounting practices, the 25
rate of capital recovery or depreciation rate is an indication of risk because it 26

Investor-Owned Utilities Industry, Nov. 26, 2008, pgs. 8-9.
WALKER, Di 22
Falls Water Co., Inc.
represents cash flow and the return of an investment. Falls Water’s average rate of 1
capital recovery is higher than the Comparable Group’s, suggesting less risk. 2
The return on equity and depreciation expense provides the margin for 3
coverage of construction expenditures. For a utility company, depreciation expense 4
is the single largest generator of cash flow. From a financial analyst’s point of 5
view, cash flow is the life blood of a utility company. Without it, a utility cannot 6
access capital markets, it cannot construct plant, and therefore, it cannot provide 7
service to its customers. 8
RISK ANALYSIS 9
Q. Please explain the information shown on Schedule 8. 10
A. Schedule 8 details the size difference between Falls Water and the Comparable 11
Group. Company size is an indicator of business risk and is summarized in Table 12
4. 13
Number of Times Larger Than Falls
Water
Water Group
Capitalization 689.3x
Revenues 440.4x
Number of Customers 139.5x
Table 4 14
As shown in Table 4, Falls Water is much smaller than the Water Group. The size 15
of a company affects risk. A smaller company requires the employment of 16
proportionately less financial leverage (i.e., debt and preferred capital) than a 17
WALKER, Di 23
Falls Water Co., Inc.
larger company to balance out investment risk. If investment risk is not balanced 1
out, then a higher cost of capital is required. 2
Q. Why is size significant to your analysis? 3
A. The size of a company can be likened to ships on the ocean, since a large ship has 4
a much better chance of weathering a storm than a small ship. The loss of a large 5
customer will impact a small company much more than a large company because a 6
large customer of a small company usually accounts for a larger percentage of the 7
small company’s sales. 8
Moreover, a larger company is likely to have a more diverse geographic 9
operation than a smaller company, which enables it to sustain earnings fluctuations 10
caused by abnormal weather in one portion of its service territory. A larger 11
company operating in more than one regulatory jurisdiction enjoys “regulatory 12
diversification” which makes it less susceptible to adverse regulatory developments 13
or eminent domain claims in any single jurisdiction. Further, a larger company 14
with a more diverse customer base is less susceptible to downturns associated with 15
regional economic conditions than a small company. For example, on average, the 16
average company in the Water Group provides water/sewer service in multiple 17
states for about 968,000 customers. The average population of the communities 18
served by the average company in the Water Group is about 3.5 million people. 19
These wide-ranging operations provide the Water Group substantial geographic, 20
economic, regulatory, weather and customer diversification. Falls Water provides 21
regulated water service to about 6,940 customers (2021). The concentration of 22
Falls Water’s business in eastern Idaho makes it very susceptible to any adverse 23
WALKER, Di 24
Falls Water Co., Inc.
development in local regulatory, economic, demographic, competitive and weather 1
conditions. 2
Further, S&P, a major credit rating agency, recognizes the importance that 3
diversification and size play in credit ratings. S&P believes some of the critical 4
factors include: regional and cross-border market diversification (mitigates 5
economic, demographic, and political risk concentration); customer diversification; 6
and regulatory regime diversification.10 7
The size of a company can be a barrier to fluid access to capital markets 8
(i.e., liquidity risk). Investors require compensation for the lack of marketability 9
and liquidity of their investments. If no compensation is provided, then investors, 10
or at least sophisticated investors, shy away. 11
Q. Is the risk related to the Company’s small size mitigated by who owns the 12
Company’s stock? 13
A. No, investment risk does not change due to ownership. Investment risk is unique 14
to an enterprise, not who owns that enterprise. For example, the market yield 15
provided by a bond does not change based on the geographic distribution of its 16
investors, the wealth of its investors, or the nationality of its investors and the same 17
to true for common stock. That is, common stocks do not provide different amounts 18
of dividends depending on who owns the stock. Similarly, a fair rate of return for 19
a business enterprise should not change based on the composition of its investors 20
either. 21

in The Investor-Owned Utilities Industry, Nov. 26, 2008.
WALKER, Di 25
Falls Water Co., Inc.
Q. Is the impact of size commonly recognized? 1
A. Yes, the National Association of Regulatory Utility Commissioners (“NARUC”), 2
and the majority of acclaimed financial texts, recognize that size affects relative 3
business risk. Liquidity risk and the existence of the small firm effect relating to 4
business risk of small firms are well-documented in financial literature.11 Investors’ 5
expectations reflect the highly-publicized existence of the small firm effect. For 6
example, many mutual funds classify their investment strategy as small 7
capitalization in an attempt to profit from the existence of the small firm effect. 8
As previously discussed, S&P recognizes that size plays a role in credit 9
ratings. 10
Standard & Poor’s has no minimum size criterion for any 11
given rating level. However, size turns out to be 12
significantly correlated to ratings. The reason: size often 13
provides a measure of diversification, and/or affects 14
competitive position. . . . Small companies are, almost by 15
definition, more concentrated in terms of product, number of 16
customers, or geography. In effect, they lack some elements 17
of diversification that can benefit larger companies. To the 18
extent that markets and regional economies change, a 19
broader scope of business affords protection. This 20
consideration is balanced against the performance and 21
prospects of a given business. . . . In addition, lack of 22
financial flexibility is usually an important negative factor in 23
the case of very small companies. Adverse developments 24
that would simply be a setback for companies with greater 25
resources could spell the end for companies with limited 26
access to funds.12 27

As shown on Schedule 9, size plays a role in the composition of investors, and 1
hence liquidity. In 2021, about 112% of the Water Group’s shares traded while the 2
larger companies comprising the S&P Utilities had a much higher trading volume 3
of 149%. Insiders13 hold more than eight times more, as a percent to total, of the 4
Water Group’s shares than the S&P Utilities. Currently, only about 71% of the 5
Water Group shares are held by institutions14 while the larger companies 6
comprising the S&P Utilities had much higher institutional holdings of 80%. Due 7
to small size and less interest by financial institutions, fewer security analysts 8
follow the Comparable Group and none follow Falls Water. 9
The lack of trading activity may affect the cost of equity estimates for small 10
entities such as Falls Water and the Water Group. When stock prices do not change 11
because of inactive trading activity, estimates of dividend yield for use in a dividend 12
cash flow model and beta estimates for use in the capital asset pricing model are 13
affected. In a stock market that is generally up, the beta estimates for the 14
Comparable Companies may be understated due to thin trading. 15
Q. Do Falls Water and the Comparable Companies have similar operating risks? 16
A. Yes. From an operations standpoint, Falls Water and the Comparable Companies 17
have similar risks and are indistinguishable. Both are required to meet Clean Water 18
Act and Safe Drinking Water Act requirements and are also required to provide 19

safe and reliable services to their customers and comply with Commission 1
regulations. 2
Q. Is there any single measure that best shows investment risk from a common 3
stockholder’s perspective? 4
A. No. However, from a creditor’s viewpoint, the best measure of investment risk is 5
debt rating. The debt rating process generally provides a good measure of 6
investment risk for common stockholders because the factors considered in the debt 7
rating process are usually relevant factors that a common stock investor would 8
consider in assessing the risk of an investment. Credit rating agencies, such as 9
S&P, assess the risk of an investment into two categories based on: fundamental 10
business analysis; and financial analysis.15 The business risk analysis includes 11
assessing: Country risk; industry risk; competitive position; and profitability/peer 12
group comparisons. The financial risk analysis includes assessing: accounting; 13
financial governance and policies/risk tolerance; cash flow adequacy; capital 14
structure/asset protection; and liquidity/short-term factors. 15
Q. What is the bond rating of Falls Water and the Comparable Group? 16
A. Page 1 of Schedule 10 shows the average bond/credit rating Comparable Group. 17
The Comparable Group has an A credit profile and Falls Water does not have bonds 18
rated. The major bond rating/credit rating agencies append modifiers, such as +, - 19
for S&P and 1, 2, and 3 for Moody’s Investors Service (“Moody’s”) to each generic 20
rating classification. For example, an “A” credit profile is comprised of three 21

Risk Matrix Expanded, May 27, 2009 and Standard & Poor’s, Criteria Corporates General: Corporate
Methodology, November 19, 2013.
WALKER, Di 28
Falls Water Co., Inc.
subsets such as A+, A, A- for S&P or A1, A2 or A3 for Moody’s. The modifier of 1
either “+” or “1” indicates that the obligation ranks in the higher end of its generic 2
rating category; the modifier “2” indicates a mid-range ranking; and the modifier 3
of “-“ or “3” indicates a ranking in the lower end of that generic rating category. 4
S&P and Moody’s publish financial benchmark criteria necessary to obtain 5
a bond rating for different types of utilities. As a generalization, the higher the 6
perceived business risk, the more stringent the financial criteria so the sum of the 7
two, business risk and financial criteria, remains the same. 8
Q. What are some financial benchmarks applied by credit rating agencies for 9
rating public utility debt? 10
A. S&P describes their range of financial benchmarks as 11
Risk-adjusted ratio guidelines depict the role that financial ratios 12
play in Standard & Poor’s rating process, since financial ratios are 13
viewed in the context of a firm’s business risk. A company with a 14
stronger competitive position, more favorable business prospects, 15
and more predictable cash flows can afford to undertake added 16
financial risk while maintaining the same credit rating. The 17
guidelines displayed in the matrices make explicit the linkage 18
between financial ratios and levels of business risk.16 19
Q. What other information is shown on Schedule 10? 20
A. Page 2 of Schedule 10 summarizes the application of S&P’s and Moody’s measures 21
of financial risk for Falls Water and the Comparable Group. S&P’s and Moody’s 22
measures of financial risk are broader than the traditional measure of financial risk 23
(i.e., leverage). Besides reviewing amounts of leverage employed, S&P and 24
Moody’s also focus on earnings protection and cash flow adequacy. 25

WALKER, Di 29
Falls Water Co., Inc.
As is evident from the information shown on page 2 of Schedule 10, for the 1
five years ending in 2021 and for the year 2021, Falls Water’s cash flow adequacy 2
ratios were generally higher than the Comparable Companies in most instances.17 3
Comparing the Falls Water and the Water Group’s measures of cash flow adequacy 4
shows that the Falls Water has experienced a higher level of cash flow adequacy 5
than Water Group, indicating that Falls Water is a lower investment risk than the 6
Water Group. Based solely upon Falls Water’s historical ratios, it is my opinion 7
that Falls Water’s credit profile is similar but higher to the Comparable Companies. 8
However, based solely upon Falls Water’s size, it is my opinion that Falls 9
Water’s credit profile is lower than the Comparable Groups’. Based on Falls 10
Water’s smaller size, it is highly likely that Falls Water’s credit profile is below 11
BBB (i.e., BB), based solely upon size. An analysis of corporate credit ratings, 12
shown on page 4 of Schedule 10, indicates that there is an 90% (100%-0%-1%-6%-13
3%=90%) chance that Falls Water’s credit profile falls below BBB based on their 14
small size alone.18 As S&P has stated, size is significantly correlated to credit 15
ratings. 16
An analysis of corporate credit ratings, summarized on page 4 of Schedule 17
10, found The Berkshire Gas Company (“Berkshire”) to be the smallest utility with 18
a credit rating. Berkshire’s credit rating is only A- despite having a capitalization 19
17 Falls Water’s various cash flow coverages reflect their actual common equity ratio that ranged from
74.1% to 89.7% during the years analyzed.
18 Additionally, I found no companies with bonds rated higher than BB that had less than $198 million of
capitalization. Of these companies with less than $198 million of capitalization, only 17% had bonds rated
BB and 83% had bonds rated BB.
WALKER, Di 30
Falls Water Co., Inc.
comprised of about $198 million and a common equity ratio of 70%. According to 1
this analysis of corporate credit ratings, the smallest rated water utility is The York 2
Water Company (“York”). York’s credit rating is only A- notwithstanding having 3
a capitalization of about $301 million and a common equity ratio of 51%. 4
In order to compete with the Comparable Group for capital, in the future, it 5
will be necessary for Falls Water to achieve higher returns on equity, and increased 6
cash flow just to maintain a similar credit quality. 7
S&P has stated: 8
... low authorized returns may affect the industry’s ability to attract 9
necessary capital to develop new water supplies and upgrade the 10
quality of existing supplies . . . Traditional ratemaking policy has not 11
provided sufficient credit support during the construction cycle of the 12
electric industry over the past 15 years. To avoid a repeat in the water 13
industry, regulators must be aware of the increased challenges the 14
industry faces.19 15
Investors will not provide the equity capital necessary for increasing the amount of 16
common equity in a capital structure unless the regulatory authority allows an 17
adequate rate of return on the equity.20 18
Q. What do you conclude from the various measures of investment risk 19
information you have testified to? 20
A. A summary of my conclusions regarding the risk analyses discussed previously is 21
shown in Table 5. Overall, the information summarized in Table 5 indicates that 22
Falls Water has similar investment risk as the Water Group. 23

term government bonds and A-rated public utility bonds available to me at the time 1
Schedule 11 was prepared, I conclude that the market believes that if the 2
Comparable Companies issued new long-term bonds near term, they would be 3
priced to yield about 5.4% based upon a credit profile of “A.” Further, it is 4
reasonable to conclude the market anticipates that long-term government bonds will 5
be priced to yield about 3.8%, near term. 6
Since October 2008, the Federal Reserve has been monetizing US Treasury 7
debt to artificially suppress interest rates through expansionary money policies (i.e., 8
quantitative easing). The Federal Reserve, with effectively unlimited money at its 9
disposal, intervenes at any time it wishes, in whatever volume it wishes, to make 10
sure that Treasury bond and bill prices and yields are exactly what the Federal 11
Reserve wants them to be. The US Treasury bond market, and mortgage market, 12
has become an artificial market with no connection to objective risk and interest 13
rates. 14
In August 2011, the Federal Reserve began “Operation Twist.” Under 15
“Operation Twist,” the Federal Reserve began buying $400 billion of long-dated or 16
long-term US Treasury debt, financed by selling short-term US Treasury debt with 17
three years to go or less. The goal of “Operation Twist” was to try to drive long-18
term rates lower, which the Federal Reserve thought would help the mortgage 19
market. This process has created an artificial demand for the US Treasury debt 20
themselves, and easily drives interest rates artificially lower and deceives investors 21
into believing US Treasury debt is safe with wide demand. This has resulted in the 22
WALKER, Di 33
Falls Water Co., Inc.
entire capital system being impacted by the Federal Reserve’s distortion of the price 1
of risk. 2
In the real world of economics, the borrower pays an interest rate to 3
a lender, who makes money (interest) by taking on the risk of 4
lending and deferring gratification. The lender is willing to not 5
spend his money now. In a free market economy, interest rates are 6
essentially a price put on money, and they reflect the time preference 7
of people. Higher interest rates reflect a high demand for borrowing 8
and lower savings. But the higher rates automatically correct this 9
situation by encouraging savings and discouraging borrowing. 10
Lower interest rates will work the opposite way. When the 11
government/central bank tampers with interest rates, savings and 12
lending are distorted, and resources are misallocated. This is evident 13
in looking back on the housing bubble. The artificially low interest 14
rates signaled that there was a high amount of savings. But it was a 15
false signal. There was also a signal for people to borrow more. 16
Again, it was a false signal. As these false signals were revealed, 17
the housing boom turned into a bust.21 18
More recently, in response to COVID-19, the Federal Reserve provided 19
monetary and fiscal stimulus to increase liquidity in the form of new fiscal stimulus 20
programs and rate cuts. “For context, new fiscal stimulus and total fiscal deficits in 21
the US are roughly double the levels seen in 2008-2009, and the US fiscal deficit 22
we project for 2020 of 15%-18% is only matched by deficits seen at the height of 23
WWII in 1942-1943.”22 The combined result of these actions by the Federal 24
Reserve and investors’ flight to quality resulted in artificial and historically low 25
risk-free rates as measured by the 30-year treasury bond yield. 26

Q. What are some of the results from the FED’s monetary and fiscal stimulus? 1
A. The FED’s quantitative easing of expanding its own balance sheet, by buying 2
bonds, and therefore injecting money into the economy, floods the economy with 3
additional cash, keeping interest rates low and impacts equity markets. 4
Additionally, the FED’s uninterrupted and aggressive monetary expansion policy 5
necessarily puts pressure on inflation. The FED’s monetary and fiscal stimulus, 6
which included artificial and historically low interest rates, have produced some of 7
the highest inflation rates in the last 40 years according to CNBC. 8
Inflation rose 9.1% in June, even more than expected, as consumer 9
pressures intensify. 10
11
Shoppers paid sharply higher prices for a variety of goods in June as 12
inflation kept its hold on a slowing U.S. economy, the Bureau of 13
Labor Statistics reported Wednesday. 14
15
The consumer price index, a broad measure of everyday goods and 16
services related to the cost of living, soared 9.1% from a year ago, 17
above the 8.8% Dow Jones estimate. That marked the fastest pace 18
for inflation going back to November 1981.23 19
In response to the recent level of inflation rates, the Federal Reserve 20
announced its goal of increasing interest rates as high as needed to get inflation 21
back to 2%. 22
Americans are headed for a painful period of slow economic growth 23
and possibly rising joblessness as the Federal Reserve raises interest 24
rates to fight high inflation, U.S. central bank chief Jerome Powell 25

for the world's biggest economy. 27

to restrict growth, and would keep them there "for some time" to 1
bring down inflation that is running at more than three times the 2
Fed's 2% goal. 3

"Reducing inflation is likely to require a sustained period of below-5
trend growth," Powell said. "While higher interest rates, slower 6
growth, and softer labor market conditions will bring down 7
inflation, they will also bring some pain to households and 8
businesses. These are the unfortunate costs of reducing inflation. 9
But a failure to restore price stability would mean far greater pain." 10
11
As that pain increases, Powell said, people should not expect the Fed 12
to dial back its monetary policy quickly until the inflation problem 13
is fixed.24 14
Prospectively the capital markets will be affected by the upcoming 15
unprecedented large Treasury financings coupled with increased interest rates. 16
Investors provide capital based upon risk and return opportunities and investors will 17
not provide common equity capital when higher risk-adjusted returns are available. 18
COMMON EQUITY COST RATE ESTIMATE 19
Q. What is the best method of estimating common equity cost rates? 20
A. There is no single method (model) suitable for estimating the cost rate for common 21
equity. While a single investor may rely solely upon one model in evaluating 22
investment opportunities, other investors rely on different models. Most 23
sophisticated investors who use an equity valuation model rely on many models in 24
evaluating their common equity investment alternatives. Therefore, the average 25
price of an equity security reflects the results of the application of many equity 26
models used by investors in determining their investment decisions. 27

WALKER, Di 36
Falls Water Co., Inc.
The application of any single model to estimate common equity cost rates 1
is not appropriate because the security price for which the equity cost rate is being 2
estimated reflects the application of many models used in the valuation of the 3
investment. That is, the price of any security reflects the collective application of 4
many models. Accordingly, if only one model is used to estimate common equity 5
cost rates, that cost rate will most likely be different from the collective market’s 6
cost rates because the collective valuation in the market reflects more than one 7
method. 8
Noted financial texts, investor organizations and professional societies all 9
endorse the use of more than one valuation method. “We endorse the dividend 10
discount model, particularly when used for establishing companies with consistent 11
earnings power and when used along with other valuation models. It is our view 12
that, in any case, an investor should employ more than one model.”25 13
The American Association of Individual Investors state, “No one area of 14
investment is suitable for all investors and no single method of evaluating 15
investment opportunities has been proven successful all of the time.”26 16
In their study guide, the National Society of Rate of Return Analysts state, 17
“No cost of equity model or other concept is recommended or emphasized, nor is 18
any procedure for employing any model recommended . . . it remains important to 19

recognize that alternative methods exist and have merit in cost of capital estimation. 1
To this end, analysts should be knowledgeable of a broad spectrum of cost of capital 2
techniques and issues.”27 3
Several different models should be employed to measure accurately the 4
market-required cost of equity reflected in the price of stock. Therefore, I used 5
three recognized methods: the DCF shown on Schedule 12, the CAPM shown on 6
Schedule 17, and the RP shown on Schedule 18. 7
DISCOUNTED CASH FLOW 8
Q. Please explain the discounted cash flow model. 9
A. The DCF is based upon the assumption that the price of a share of stock is equal to 10
a future stream of cash flows to which the holder is entitled. The stream of cash 11
flows is discounted at the investor-required cost rate (cost of capital). 12
Although the traditional DCF assumes a stream of cash flow into perpetuity, 13
a termination, or sale price can be calculated at any point in time. Therefore, the 14
return rate to the stockholder consists of cash flow (earnings or dividends) received 15
and the change in the price of a share of stock. The cost of equity is defined as: 16
...the minimum rate of return that must be earned on equity 17
finance and investments to keep the value of existing 18
common equity unchanged. This return rate is the rate of 19
return that investors expect to receive on the Company’s 20
common stock . . . the dividend yield plus the capital gains 21
yield . . . 28 22

WALKER, Di 38
Falls Water Co., Inc.
Q. Please explain how you calculated your dividend yield in the DCF shown on 1
Schedule 12. 2
A. As shown on page 1 of Schedule 12, I used the average dividend yield of 1.8% for 3
the Water Group. The individual dividend yields are shown on page 2 of Schedule 4
12 and are based upon the most recent months’ yield, February 2023, and the 5
twelve-month average yield, ending February 2023. The second input to a market 6
DCF calculation is the determination of an appropriate share price growth rate. 7
Q. What sources of growth rates did you review? 8
A. I reviewed both historical and projected growth rates. Schedule 13 shows the array 9
of projected growth rates for the Comparable Companies that are published. 10
Specific historical growth rates are shown for informational purposes because I 11
believe the meaningful historical growth rates are already considered when analysts 12
arrive at their projected growth rates. Nonetheless, some investors may still rely on 13
historical growth rates. 14
Q. Please explain the sources of the projected growth rates shown on Schedule 13. 15
A. I relied upon four sources for projected growth rates, First Call, S&P, Zacks 16
Investment Research and Value Line.29 17
Q. Did you review any other growth rates besides those shown on Schedule 13? 18
A. Yes. I reviewed EPS growth rates reflecting changes in return rates on book 19
common equity (ROE) over time. I summarized recent ROEs on page 1 of 20
29With the exception of Value Line, the earnings growth rate projections are consensus estimates five-year
EPS estimates. These consensus estimates are compiled from more than 1,700 financial analysts and
brokerage firms nationwide. It should be noted that none of the consensus forecasts provides projected DPS
estimates. Value Line publishes projected Cash flow, EPS and DPS five-year growth projections as well.

Schedule 14 and compared those to the Water Group’s higher levels projected to 1
be achieved by Value Line, as shown on page 2 of Schedule 14. ROEs increase 2
when EPS grows at much higher/faster rates than book value. 3
I also reviewed industry specific average projected growth rates that are 4
published by Zacks for the industries in which the Comparable Companies operate. 5
According to Zacks, the Water Group’s industry is projected to have EPS growth 6
rates that average 9.8% over the next five years. 7
Q. What do you conclude from the growth rates you have reviewed? 8
A. Table 6 summarizes some of the various growth rates reviewed. 9

Academic studies suggest that growth rate conclusions should be tested for 11

combined result of adding the growth rate to the market value dividend yield must 15
provide a sufficient margin over yields of public utility debt. 16
WALKER, Di 40
Falls Water Co., Inc.
Q. What method did you use to arrive at your growth rate conclusion? 1
A. No single method is necessarily the correct method of estimating share value 2
growth. It is reasonable to assume that investors anticipate that the Water Group’s 3
current ROE will expand to higher levels. The published historical earnings growth 4
rates for the Water Group averages 5.4%. Because there is not necessarily any 5
single means of estimating share value growth, I considered all of this information 6
in determining a growth rate conclusion for the Comparable Companies. 7
Moreover, while some rate of return practitioners would advocate that 8
mathematical precision should be followed when selecting a growth rate, the fact 9
is that investors do not behave in the same manner when establishing the market 10
price for a stock. Rather, investors consider both company-specific variables and 11
overall market sentiment such as inflation rates, interest rates and economic 12
conditions when formulating their capital gains expectations. This is especially 13
true when one considers the relatively meaningless negative growth rates. That is, 14
use of a negative growth rate in a DCF implies that investors invest with the 15
expectation of losing money. 16
The range of growth rates previously summarized supports the 17
reasonableness of an expected 7.0% growth rate for the Water Group based 18
primarily on the projected five-year growth rates and considering the Water 19
Group’s industry projected EPS growth rates of 9.8%. Like the projected growth 20
rates, this investor-expected growth rate of 7.0% is based on a survey of projected 21
and historical growth rates published by established entities, including First Call, 22
S&P, Zacks Investment Research and Value Line. Use of information from these 23

unbiased professional organizations provides an objective estimation of investor’s 1
expectations of growth. Based on the aforesaid, all growth rates for the Comparison 2
Companies have been considered and have been given weight in determining a 3
7.0% growth rate for the Water Group. 4
Q. What is your market value DCF estimate for the Comparable Companies? 5
A. The market value DCF cost rate estimate for the Water Group is 8.9%, as detailed 6
on page 1 of Schedule 12. 7
Q. Are there other considerations that should be taken into account in reviewing 8
a market value capitalization DCF cost rate estimate? 9
A. Yes. It should be noted that although I recommend specific dividend yields for the 10
Comparable Group, I recommend that less weight be given to the resultant market 11
value DCF cost rate due to the market’s current market capitalization ratios and the 12
impact that the market-to-book ratio has on the DCF results. The Comparable 13
Companies’ current market-to-book ratios of 302% and low dividend yields are 14
being affected by the aforementioned policy of the Federal Reserve that has resulted 15
in the mispricing of capital due to artificial interest rates, not DCF fundamentals. 16
Although the DCF cost for common equity appears to be based upon 17
mathematical precision, the derived result does not reflect the reality of the 18
marketplace since the model proceeds from unconnected assumptions. The 19
traditional DCF derived cost rate for common equity will continuously understate 20
or overstate investors’ return requirements as long as stock prices continually sell 21
above or below book value. A traditional DCF model implicitly assumes that stock 22
price will be driven to book value over time. However, such a proposition is not 23
WALKER, Di 42
Falls Water Co., Inc.
rational when viewed in the context of an investor purchasing stock above book 1
value. It is not rational to assume that an investor would expect share price to 2
decrease 67% (100%÷302%=33%-100%=67%) in value to equal book value. 3
Utility stocks do not trade in a vacuum. Utility stock prices, whether they 4
are above or below book value, reflect worldwide market sentiment and are not 5
reflective of only one element. 6
Q. What do you mean by your statement that utility stocks are not traded in a 7
vacuum? 8
A. Utility stocks cannot be viewed solely by themselves. They must be viewed in 9
the context of the market environment. Table 7 summarizes recent market-to-10
book ratios (“M/B”) for well-known measures of market value reported in the 11
March 13, 2023 issue of Barron’s and the Water Group’s average M/B as shown 12

Table 7. 4
Q. How does a traditional DCF implicitly assume that market price will equal 5
book value? 6
A. Under traditional DCF theory, price will equal book value (M/B=1.00) only when 7
a company is earning its cost of capital. Traditional DCF theory maintains that a 8
company is under-earning its cost of capital when the market price is below book 9
value (M/B<1.00), while a company over-earning its cost of capital will have a 10
market price above its book value (M/B>1.00). If this were true, it would imply 11
that the capitalistic free-market is not efficient because the overwhelming majority 12
of stocks would currently be earning more than their cost of capital. Table 7 shows 13
that most stocks sell at an M/B that is greater than 1.0. 14
Q. Please explain why such a phenomenon would show that the capitalistic free-15
market is not efficient. 16
A. Historically, the S&P 500, which represented the largest 500 companies listed on 17
exchanges in the United States, have not sold at an M/B of 1.0 during the last 24-18
years, 1999-2022. Based upon the traditional DCF assumption, which suggests that 19
companies with M/Bs greater than 1.0 earn more than their cost of capital, this data 20
would suggest that the S&P 500 companies have earned more than their cost of 21
capital while competing in a competitive environment over the 24-year period. In 22
WALKER, Di 44
Falls Water Co., Inc.
a competitive market, new companies would continually enter the market up to the 1
point that the earnings rate was at least equal to their cost of capital. 2
During this period the S&P 500 sold at an average M/B of 306% while 3
experiencing a ROE of 18.0% over a period in which interest rates averaged 3.9%. 4
It is important to note that during this period the S&P 500 M/B ranged from 192% 5
to 490%, all while competing in competitive markets. 6
Q. What is the significance of S&P 500 m/b and the cost of capital for a water 7
utility? 8
A. As stated previously, utility stocks do not trade in a vacuum. They must compete 9
for capital with other firms including the S&P 500 stocks. Over time, there has 10
been a relationship between M/Bs of S&P 500 stocks and utility stocks. Although 11
S&P 500 stocks have generally sold at a higher multiple of book value than utility 12
stocks, both have tracked in similar directions. Because utility and S&P 500 stock 13
prices relative to book values move in similar directions, it is irrational to conclude 14
that stock prices that are different from book value, either higher or lower, suggests 15
that a firm is over-or under-earning its cost of capital when competitive, free-16
markets exist. 17
Q. Does the market value DCF provide a reasonable estimate of the Water 18
Group’s common equity cost rate? 19
A. No, the DCF only provides a reasonable estimate of the Comparable Group’s 20
common equity cost rate when their market price and book value are similar 21
WALKER, Di 45
Falls Water Co., Inc.
(M/B=100%).30 A DCF will overstate a common equity cost rate when M/Bs are 1
below 100% and understate when they are above 100%. Since the Comparable 2
Group’s current M/Bs average 302%, the DCF understates their common equity 3
cost rate. Schedule 15 provides a numerical illustration of the impact of M/Bs on 4
investors’ market returns and DCF returns. The reason that DCF understates or 5
overstates investors’ return requirements depending upon M/B levels is because a 6
DCF-derived equity cost rate is applied to a book value rate base while investors’ 7
returns are measured relative to stock price levels. Based upon this, I recommend 8
that less weight be given to the market value DCF cost rate unless the increased 9
financial risk, resulting from applying a market value cost rate to a book value, is 10
accounted for. 11
Q. How do you resolve the financial risk difference between market value cost 12
rates and book value cost rates? 13
A. The basic proposition of financial theory regarding the economic value of a 14
company is based on market value. That is, a company's value is based on its 15
market value weighted average cost of capital.31 The American Society of 16
Appraisers, ASA Business Valuation Standards, 2009, and the National 17
Association of Certified Valuation Analysts, Professional Standards, 2007, use the 18
same definition: 19

Weighted Average Cost of Capital (WACC). The cost of capital 1
(discount rate) determined by the weighted average, at market 2
values, of the cost of all financing sources in the business 3
enterprise's capital structure. (Emphasis added) 4
Accordingly, the market value derived cost rate reflects the financial risk or 5
leverage associated with capitalization ratios based on market value, not book 6
value. 7
As shown on page 1 of Schedule 16, for the Water Group there is a large 8
difference in leverage as a result of the average $4.400 billion difference in market 9
value common equity and book value common equity. This difference in market 10
values and book values results in debt/equity ratios based on market value of 11
26.2%/73.8% (debt/equity) verses 49.8%/50.2% (debt/equity) based on book value 12
as shown on page 1 of Schedule 16. The larger the difference between market 13
values and book values the less reliable the models’ results are because the models 14
provide an estimate of the cost of capital of market value, not book value. 15
Financial theory concludes that capital structure and firm value are related. 16
Since capital structure and firm value are related, an adjustment is required when a 17
cost of common equity model is based on market value and if its results are then 18
applied to book value. As explained previously, the market value derived cost rate 19
reflects the financial risk or leverage associated with capitalization ratios based 20
on market value, not book value. The authors Brealey, Myers and Allen provide 21
a similar definition of the cost of capital being based on market capitalization, not 22
book value, 23
The values of debt and equity add up to overall firm value (D + E = 24
V) and firm value V equals asset value. These figures are all 25
WALKER, Di 47
Falls Water Co., Inc.
market values, not book (accounting) values. The market value of 1
equity is often much larger than the book value, so the market debt 2
ratio D/V is often much lower than a debt ratio computed from the 3
book balance sheet.32 4
The work of Modigliani and Miller concludes that the market value of any 5
firm is independent of its capital structure and this is precisely the reason why an 6
adjustment is appropriate. The only way for the market value of a firm to remain 7
independent of its capital structure is if the capital cost rates change to offset 8
changes in the capital structure. If the capital cost rates do not change to offset 9
changes in the capital structure, then the value of the firm will change. Clearly an 10
adjustment is required when a cost of common equity model is based on market 11
value and if its results are then applied to book value because the capital structure 12
is changed from market value capitalization ratios to book value capitalization 13
ratios. 14
Differences in the amount of leverage employed can be quantified based 15
upon the Comparable Group’s leveraged beta being “unleveraged” through the 16
application of the a “Hamada Model.” 17
The Hamada equation is a fundamental analysis method of 18
analyzing a firm's cost of capital as it uses additional financial 19
leverage, and how that relates to the overall riskiness of the firm. 20
The measure is used to summarize the effects this type of leverage 21
has on a firm's cost of capital—over and above the cost of capital as 22
if the firm had no debt.33 23

The Hamada Model combines two financial theorems: the Modigliani-Miller 1
Theorem and the CAPM.34 On page 2 of Schedule 16 I used two Hamada Models 2
including the original Hamada formula and the Harris-Pringle formula to account 3
for the 23.7 percentage point change in common equity ratio that results from 4
changing from market value capitalization to book value capitalization. The results 5
of the application of the original Hamada formula and the Harris-Pringle formula 6
determine a range of adjustment of 0.75% to 1.20%, and average 0.98%. The 7
details of the application of the two Hamada models are shown on page 2 of 8
Schedule 16. 9
For example, the inputs to the original Hamada formula for the Water Group 10
market value capitalization consist of their raw leveraged beta of 0.66, debt ratio of 11
26.2%, preferred stock ratio of 0.0%, common equity ratio of 73.8% and combined 12
tax rate of 27.87%. The group's unleveraged beta is determined to be 0.53 through 13
the use of the following original Hamada formula: 14
Bl = Bu (1 + (1 - t) D/E + P/E) 15
where: 16
Bl = observed, leveraged beta 17
Bu = calculated, unleveraged beta 18

Falls Water Co., Inc.
common equity and combined tax rate of 27.87% results in a leveraged beta of 0.90 1
applicable to the group’s book value capitalization. Based upon the Water Group’s 2
risk premium of 5.0% and the difference between Water Group's market value 3
leveraged beta, their book value leveraged beta of 0.24 (0.90 - 0.66) indicates that 4
the Water Group’s common equity cost rate must be increased by 1.20 (0.24 x 5.0 5
= 1.20) in recognition of their book value’s exposure to more financial risk. 6
The inputs to the Harris-Pringle formula for the Water Group market value 7
capitalization consist of their raw leveraged beta of 0.66, debt ratio of 26.2%, 8
preferred stock ratio of 0.0%, common equity ratio of 73.8% and debt beta of 0.34. 9
The group's unleveraged beta is determined to be 0.58 through the use of the 10
following Harris-Pringle formula: 11
Bl = Bu + (Bu - Bd)(D/E) 12
where: 13
Bl = observed, leveraged beta 14
Bu = calculated, unleveraged beta 15
Bd = debt beta 16
D = debt ratio 17
P = preferred stock ratio 18
E = common equity ratio 19
Applying the unleveraged beta of 0.58 along with the Water Group’s book value 20
capitalization ratios of 49.8% long-term debt, 0.1% preferred stock and 50.1% 21
common equity and debt beta of 0.34 results in a leveraged beta of 0.81 applicable 22
to the group’s book value capitalization. Based upon the Water Group’s risk 23
premium of 5.0% and the difference between Water Group's market value 24
leveraged beta, their book value leveraged beta of 0.15 (0.81 - 0.66) indicates that 25
WALKER, Di 50
Falls Water Co., Inc.
the Water Group’s common equity cost rate must be increased by 0.75 (0.15 x 5.0 1
= 0.75) in recognition of their book value’s exposure to more financial risk. 2
Q. Is there another way to reflect the financial risk difference that exists as a 3
result of market capitalization ratios being significantly different from book 4
value capitalization ratios? 5
A. Yes, generally speaking. Although it is possible to know the direction of a financial 6
risk adjustment on common equity cost rate, a specific quantification of financial 7
risk differences is very difficult. Although the end result of a financial risk 8
adjustment is very subjective and specific quantification very difficult, the direction 9
of the adjustment is clearly known. However, hypothetically if the Comparable 10
Group’s debt were rated based on market value debt ratios they would command 11
an Aaa rating. The Comparison Group currently has bonds rated A based upon 12
their book value debt ratios. The yield spread on a bond rated Aaa versus A rated 13
bonds averages about 65 basis points or 0.65% as shown on page 3 of Schedule 16. 14
The result of the original Hamada formula indicates an adjustment of 15
1.20%, the Harris-Pringle formula indicates an adjustment of 0.75%, and the bond 16
yield spread approach indicates an adjustment of 0.65%. Based on the results of 17
these three approaches, I believe the Water Group’s market value common equity 18
cost rate should be adjusted upward by at least 0.80% (0.98% hamada est. + 0.65% 19
yield spread = 1.63% ÷ 2 = 0.8%) since it is going to be applied to a book value 20
equity ratio that is 23.7 percentage points less than the market value equity ratio. 21
WALKER, Di 51
Falls Water Co., Inc.
Accounting for the increased amount of leverage between market value 1
derived DCF cost rates and book value cost rates indicates a book value DCF cost 2
rate of 9.70% for the Water Group (8.9% + 0.8% = 9.70%). 3
CAPITAL ASSET PRICING MODEL 4
Q. Please briefly describe the theory of the capital asset pricing model. 5
A. The CAPM is based upon the assumption that investors hold diversified portfolios 6
and that the market only recognizes or rewards non-diversifiable (or systematic) 7
risk when determining the price of a security because company-specific risk (or 8
non-systematic) is removed through diversification. Further, investors are assumed 9
to require additional or higher returns for assuming additional or higher risk. This 10
assumption is captured by using a beta that provides an incremental cost of 11
additional risk above the base risk-free rate available to investors. The beta of a 12
security reflects the market risk or systematic risk of the security relative to the 13
market. The beta for the market is always equal to 1.00; therefore, a company 14
whose stock has a beta greater than 1.00 is considered riskier than the market, and 15
a company with a beta less than 1.00 is considered less risky than the market. The 16
base risk-free rate is assumed to be a U.S. Government treasury security because 17
they are assumed to be free of default risk. 18
Q. What risk-free rate and beta have you used in your CAPM calculation? 19
A. The risk-free rate used in CAPM should have approximately the same maturity as 20
the life of the asset for which the cost rate is being determined. Because utility 21
assets are long-lived, a long-term Treasury Bond yield serves as an appropriate 22
proxy. Previously, I estimated an appropriate risk-free rate of 3.8% based upon the 23
WALKER, Di 52
Falls Water Co., Inc.
recent and forward long-term Treasury yields. I used the average beta of 0.79 for 1
the Water Group as shown on page 1 of Schedule 17. However, as stated 2
previously, the Comparable Group’s betas are understated due to their small size 3
which affects their stock price changes. 4
Q. After developing an appropriate beta and risk-free rate, what else is necessary 5
to calculate a CAPM derived cost rate? 6
A. A market premium is necessary to determine a traditional CAPM derived cost rate. 7
The market return rate is the return expected for the entire market. The market 8
premium is then multiplied by the company specific beta to capture the incremental 9
cost of additional risk (market premium) above the base risk-free rate (long-term 10
treasury securities) to develop a risk adjusted market premium. For example, if you 11
conclude that the expected return on the market as a whole is 15% and further 12
assume that the risk-free rate is 8%, then the market premium is shown to be 7% 13
(15% - 8% = 7%). 14
Further, assume there are two companies, one of which is considered less 15
risky than the market, and therefore has a beta of less than 1.00 or 0.80. The second 16
company has a beta that is greater than 1.00 or 1.20, and is therefore considered 17
riskier than the market. By multiplying the hypothetical 7.0% market premium by 18
the respective betas of 0.80 and 1.20, risk adjusted market premiums of 5.6% (7.0% 19
x 0.80) and 8.4% (7.0% x 1.20) are shown for the company considered less risky 20
than the market and for the company considered riskier than the market, 21
respectively. 22
WALKER, Di 53
Falls Water Co., Inc.
Adding the assumed risk-free rate of 8% to the risk adjusted market 1
premiums results in the CAPM derived cost rates of 13.6% (5.6% + 8.0%) for the 2
less risky company and 16.4% (8.4% + 8.0%) for the company considered of 3
greater risk than the market. In fact, the result of this hypothetical CAPM 4
calculation shows that: (1) the least risky company, with the beta of 0.80, has a cost 5
rate of 13.6%; (2) the market, with the beta of 1.00, has a cost rate of 15.0%; and 6
(3) that the higher risk company, with a beta of 1.20, has a cost rate of 16.4%. 7
Q. How did you develop a market premium for your CAPM? 8
A. The average projected market premium of 11.1% is developed on page 2 of 9
Schedule 17. It is based upon Value Line’s average projected total market return 10
for the next three to five years of 14.9% less the risk free rate of 3.8%. I also 11
reviewed market premiums derived from Ibbotson Associates’ most recent 12
publication concerning asset returns that show a market premium of 7.5%. The 13
Ibbotson Associates’ market premium may be on the low side reflective of the 14
higher interest rate environment found during their study (i.e., 5.0%). The Value 15
Line market premium reflects the Federal Reserve’s current artificial interest rate 16
levels while the Ibbotson Associates’ market premiums reflect a higher interest rate 17
environment. 18
Q. How did you adjust for the impact that size has on the Comparable Group’s 19
beta? 20
A. The adjustment is reflected in the CAPM size premium. The CAPM size premium 21
is developed on page 4 of Schedule 17. The size premium reflects the risks 22
associated with the Comparable Group’s small size and its impact on the 23
WALKER, Di 54
Falls Water Co., Inc.
determination of their beta. This adjustment is necessary because beta (systematic 1
risk) does not capture or reflect the Comparable Group’s small size. I reduced the 2
size premium by the ratio of the Comparison Group’s beta to their respective market 3
quartile’s beta. 4
Q. What is the comparison group’s market cost of equity based upon your CAPM 5
calculation? 6
A. The CAPM based on Ibbotson Associates’ historical market returns shows a market 7
cost rate of 11.5% for the Water Group. The CAPM based on Value Line’s 8
projected market returns shows a 14.4% for the Water Group, as shown on page 1 9
of Schedule 17. The Comparable Group’s market value CAPM of 11.5% is based 10
100% on the results of the historical market returns and 0% on the projected market 11
returns. Adjusting the market value CAPM based upon the end result of the 12
application of the Hamada Model and the bond yield spread to account for the 13
difference in leverage between market value capitalization ratios and book value 14
ratios discussed previously indicates a cost rate of 12.3% for the Water Group 15
applicable to book value (11.5% + 0.8% = 12.3%). 16
RISK PREMIUM 17
Q. What is a risk premium? 18
A. A risk premium is the common equity investors’ required premium over the long-19
term debt cost rate for the same company, in recognition of the added risk to which 20
the common stockholder is exposed versus long-term debtholders. Long-term 21
debtholders have a stated contract concerning the receipt of dividend and principal 22
repayment whereas common stock investors do not. Further, long-term debtholders 23
WALKER, Di 55
Falls Water Co., Inc.
have the first claim on assets in case of bankruptcy. A risk premium recognizes the 1
higher risk to which a common stock investor is exposed. The risk premium-2
derived cost rate for common equity is the simplest form of deriving the cost rate 3
for common equity because it is nothing more than a premium above the 4
prospective level of long-term corporate debt. 5
Q. What is the appropriate estimated future long-term borrowing rate for the 6
Comparable Companies? 7
A. The estimated near term long-term borrowing rate for the Comparable Companies 8
is 5.4% based upon their credit profile that supports an A bond rating. 9
Q. What is the appropriate risk premium to be added to the future long-term 10
borrowing rate? 11
A. To determine a common equity cost rate, it is necessary to estimate a risk premium 12
to be added to the Comparable Group’s prospective long-term debt rate. Investors 13
may rely upon published projected premiums; they also rely upon their experiences 14
of investing in ultimately determining a probabilistic forecasted risk premium. 15
Projections of total market returns are shown on page 9 of Schedule 18. A 16
projected risk premium for the market can be derived by subtracting the debt cost 17
rate from the projected market return as shown on page 9 of Schedule 18. However, 18
the derived risk premium for the market is not directly applicable to the Comparable 19
Companies because they are less risky than the market. The use of 90% of the 20
market’s risk is a conservative estimation of their level of risk as compared to the 21
market. 22
WALKER, Di 56
Falls Water Co., Inc.
The midpoint of the risk premium range is 9.1% and the average for the 1
most recent quarter is 8.7% as shown on page 9 of Schedule 18. Based on this, a 2
reasonable estimate of a longer term projected risk premium is 8.7%. 3
Q. How do investors’ experiences affect their determination of a risk premium? 4
A. Returns on various assets are studied to determine a probabilistic risk premium. 5
The most noted asset return studies and resultant risk premium studies are those 6
performed by Ibbotson Associates. However, Ibbotson Associates has not 7
performed asset return studies concerning public utility common stocks. Based 8
upon Ibbotson Associates’ methodology of computing asset returns, I calculated 9
annual returns for the S&P utilities and bonds for the period 1928-2021. The 10
resultant annual returns were then compared to determine a recent risk premium 11
from a recent 20-year period, 2002-2021 and subsequent periods that were each 12
increased by ten years until the entire study period was reviewed (pages 2 and 3 of 13
Schedule 18). 14
A long-term analysis of rates of return is necessary because it assumes that 15
investors’ expectations are, on average, equal to realized long-run rates of return 16
and resultant risk premium. Observing a single year’s risk premium, either high or 17
low, may not be consistent with investors’ requirements. Further, studies show a 18
mean reversion in risk premiums. In other words, over time, risk premiums revert 19
to a longer-term average premium. Moreover, since the expected rate of return is 20
defined as “the rate of return expected to be realized from an investment; the mean 21
WALKER, Di 57
Falls Water Co., Inc.
value of the probability distribution of possible results,”35 a long-term analysis of 1
annual returns is appropriate. 2
Q. What do you conclude from the information shown on pages 2 and 3 of 3
Schedule 18? 4
A. The average of the absolute range of the S&P Utilities’ appropriate average risk 5
premium (i.e., bonds rated AAA to A) was 3.8% during the seven periods studied, 6
as calculated from page 2 of Schedule 18. The credit adjusted longer term risk 7
premiums (i.e., bonds rated A), 1928-2021, averages 4.3%. The appropriate 8
average (i.e., bonds rated AAA to A) longer term risk premiums, 1928-2021, have 9
an absolute range of 4.3% to 5.2%, and averages 4.6%. 10
The aforementioned premiums are based on total returns for bonds; and 11
reflect their price risk. A bond’s price risk is not related to its credit quality and is 12
eliminated when a bond is held to maturity from time of purchase. Using the 13
income returns, page 4 of Schedule 18, for bonds eliminates price risk and better 14
measures an investor’s required return based on credit quality. The appropriate 15
average risk premium (i.e., bonds rated AAA to A) based on income returns was 16
5.5% during the seven periods studied. The credit adjusted longer term risk 17
premiums (i.e., bonds rated A), 1928-2021, averages 4.9%. The appropriate 18
average (i.e., bonds rated AAA to A) longer term risk premiums, 1928-2021, have 19
an absolute range of 4.9% to 5.3%, and averages 5.1%. 20

WALKER, Di 58
Falls Water Co., Inc.
Q. What information is shown on page 4 of Schedule 18? 1
A. Page 4 of Schedule 18 proves and measures the negative relationship between 2
interest rate levels and the resulting risk premium. That is, risk premiums are 3
generally higher when interest rates are low and risk premiums are generally lower 4
when interest rates are high. This was proven by sorting the 94-year period, 1928 5
to 2021, annual returns based on interest rate level from lowest interest rate to 6
highest interest rate and distributing the results into two equal groups, a 47-year 7
low interest rate environment group and a 47-year high interest rate environment 8
group. 9
During the period 1928-2021, the 47 years with the lowest interest rates had 10
an average interest rate of 2.9% and reflected a range of interest rates from 1.4% to 11
4.1%. This period resembles the current interest rate environment of 3.8% 12
discussed previously regarding the CAPM's risk free rate. The risk premium based 13
on total returns during this low interest rate environment produced the appropriate 14
average (i.e., bonds rated AAA to A) longer term risk premium of 6.4% and a credit 15
adjusted longer term risk premium (i.e., bonds rated A) of 5.6%. The annual 16
income return based risk premium during this low interest rate environment 17
produced the appropriate average (i.e., bonds rated AAA to A) longer term risk 18
premium of 7.5% and a credit adjusted longer term risk premium (i.e., bonds rated 19
A) of 7.2%. 20
However, during the period 1928-2021, the 47 years with the highest 21
interest rates had an average interest rate of 7.2% and reflected a range of interest 22
rates from 4.1% to 13.5%. This period is far different from the current interest rate 23
WALKER, Di 59
Falls Water Co., Inc.
environment of 3.8%. The risk premium based on total returns during the highest 1
interest rate environment produced an average longer term risk premium of 3.0% 2
over bonds rated AAA to A and a credit adjusted longer term risk premium (i.e., 3
bonds rated A) of only 2.9%. The annual income return based risk premium during 4
the highest interest rate environment produced an average longer term risk premium 5
of 2.8% over bonds rated AAA to A and a credit adjusted longer term risk premium 6
(i.e., bonds rated A) of only 2.7%. 7
Over time, risk premiums are mean reverting. They constantly move toward 8
a long-term average reflecting a long-term level of interest rates. That is, an above-9
average risk premium will decrease toward a long-term average while a below-10
average risk premium will increase toward a long-term average. In any single year, 11
of course, investor-required rates of return may not be realized and in certain 12
instances, a single year’s risk premiums may be negative. Negative risk premiums 13
are not indicative of investors’ expectations and violate the basic premise of finance 14
concerning risk and return. Negative risk premiums usually occur only in the stock 15
market’s down years (i.e., the years in which the stock markets’ return was 16
negative). 17
When interest rate levels are not considered the credit adjusted longer term 18
risk premium (i.e., bonds rated A), 1928-2021, averages 4.6%, discussed previously 19
regarding pages 2 and 3 of Schedule 18. However, the annual income return based 20
risk premium during the low interest rate environment produced a credit adjusted 21
longer term risk premium (i.e., bonds rated A) of 7.2%. Since this period’s interest 22
rate environment resembles the current interest rate environment of 3.8%, a 23
WALKER, Di 60
Falls Water Co., Inc.
reasonable estimate of investors risk premium based on historical returns is based 1
on a 50% weighting on the results of the entire 1928-2021 historical market returns 2
and a 50% weighting on the results of the low interest rate environment to produce 3
a 5.5% historical risk premium. However, I recognize that the current interest rate 4
environment of 3.8% is close to the upper end of the low interest rate environment, 5
which ranged from 1.4% to 4.1%, and have lowered my estimate of the risk 6
premium to 5.0%. 7
Adding the risk premium of 5.0% for the Comparable Group to the 8
prospective cost of newly-issued long-term debt of 5.4% results in a market value 9
risk premium derived cost rate for common equity of 10.4% as reflected on page 1 10
of Schedule 18. Adjusting the market value risk premium based upon the end result 11
of the application of the Hamada Model and the bond yield spread to account for 12
the difference in leverage between market value capitalization and book value ratios 13
discussed previously indicates a cost rate of 11.2% applicable to book value (10.4% 14
+ 0.8% = 11.2%). 15
SUMMARY OF COMMON EQUITY COST RATE 16
Q. What is your Comparable Group’s common equity cost rate? 17
A. Based upon the results of the models employed, the Water Group’s common equity 18
cost rate is in the range of 9.7% to 12.3% as reflected on Schedule 19. Based upon 19
this data, the common equity cost rate for the Water Group is at least 11.00%. My 20
recommendation is based upon the Water Group’s 11.00% common equity cost 21
rate. 22
WALKER, Di 61
Falls Water Co., Inc.
Q. Do you recommend a cost of common equity of 11.00% for Falls Water? 1
A. Yes. Based upon the financial analysis and risk analysis, I conclude that Falls 2
Water is exposed to overall similar investment risk as the Comparable Group. This 3
is evidenced by the factors summarized in Table 5 discussed previously. 4
The results of the three models employed for the Water Group show a 5
current range of common equity cost applicable to book value of Falls Water of 6
9.70% (DCF), 12.30% (CAPM), and 11.20% (RP) as shown in Table 8. 7

Water’s Equity Cost Rates

CAPM 12.30

Table 8 8
Q. What is your common equity cost rate recommendation for Falls Water? 9
A. As discussed above and as shown in Schedule 19, I recommend a 11.00% common 10
equity cost rate for Falls Water. 11
Q. Have you checked the reasonableness of your recommended common equity 12
rate for Falls Water? 13
A. Yes. Page 2 of Schedule 14 reflects the average projected earned return on average 14
book common equity for the companies in the Comparable Group for the period 15
2025-2027, which is shown to average 10.7%. For 2021, the Comparable Group 16
earned a return on common equity of 11.3% and earned a return on common equity 17
of 10.5% in 2020, as shown on page 3 of Schedule 6. Given the large degree to 18
which regulatory lag and attrition impacts water utilities earning, the range of the 19
WALKER, Di 62
Falls Water Co., Inc.
comparable utilities’ projected and actual earned returns suggests that my 1
recommendation that Falls Water be permitted an opportunity to earn 11.00% is 2
reasonable, if not conservative. 3
OVERALL RATE OF RETURN RECOMMENDATION 4
Q. What is your overall fair rate of return recommendation for the Falls Water? 5
A. Based upon the recommended capital structure and my estimate of the Falls Water’s 6
common equity cost rate, I recommend an overall fair rate of return of 8.12%. The 7
details of my recommendation are shown on Schedule 1. 8
Q. Have you tested the reasonableness of your overall fair rate of return 9
recommendation? 10
A. Yes. If my recommended overall rate of return is actually earned, it will give Falls 11
Water ratios that will allow Falls Water to present a financial profile that will enable 12
it to attract capital necessary to provide safe and reliable water service, at 13
reasonable terms. 14
Q. Does that conclude your direct testimony? 15
A. Yes, it does.16

"The simple numerical illustration....demonstrates the impact of market-to-book
ratios on the DCF market return....The DCF cost rate of 10%, made up of a 5%
dividend yield and a 5% growth rate, is applied to the book value rate base of $50
to produce $5.00 of earnings. Of the $5.00 of earnings, the full $5.00 are required
for dividends to produce a dividend yield of 5.0% on a stock price of $100.00, and
no dollars are available for growth. The investor's return is therefore only 5%
versus his required return of 10%. A DCF cost rate of 10%, which implies $10.00
of earnings, translates to only $5.00 of earnings on book value, or a 5%
return.....Therefore, the DCF cost rate understates the investor's required return
when stock prices are well above book, as is the case presently."

CAPM
The Water Group Followed by Analysts
Notes: (1) A projected market premium is based upon the projected market return rate derived from the
Value Line Summary and Index for the various dates shown. For example, Value Line
projects (Feb-23) that the market will appreciate in price 55% over the next three to five years. Using
a four-year midpoint estimate, Value Line's appreciation potential equates to 11.6%
annually ([1.55]^.25). Additionally, Value Line estimates the market will have a dividend yield of 2.1%.
Combining the market dividend yield of 2.1% with the market appreciation results in
a projected market return rate of 13.7% (11.6% + 2.1%).
(2)Mid point of the month-end total market returns in Column E.
(3)Average total market return in Column E.
(4)As discussed in the direct testimony, the risk-free rate is 3.8%.
(5) The historical market premium is based upon studies conducted by Ibbotson Associates concerning
asset returns. Ibbotson Associates' asset return studies are the most noted asset return rate
studies available today. The results are widely disseminated throughout the investment
public. Ibbotson Associates' long-term common stock total market return is 12.33% which, when
reduced by the long-term historic risk-free rate of 4.87% results in a market premium of
7.5% (12.33% - 4.87%).

Notes: (1) Based upon the current and prospective long-term debt cost rates, it is
reasonable to expect that if the comparable group (i.e., Water Group)
issued new long-term bonds, it would both be priced to yield about
5.4% based upon credit profiles of A for the Water Group.
(2) A 5% risk premium is concluded for the Group after reviewing the
tabulation of risk spreads shown on pages 2, 3, 4 and 5 of this Schedule.
