INT-G-22-07 DIRECT TESTIMONY OF ANN E. BULKLEY FOR INTERMOUNTAIN GAS COMPANY December 1, 2022 PAGE 2 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Please state your name and business address. 1 A. My name is Ann E. Bulkley. My business address is One Beacon Street, Suite 2600, 2 Boston, Massachusetts 02108. I am a Principal at The Brattle Group (“Brattle”), a 3 consulting firm that advises clients on regulatory finance and ratemaking issues. 4 On whose behalf are you submitting this Prepared Direct Testimony? 5 A. I am submitting this testimony before the Idaho Public Utilities Commission 6 (“Commission”) on behalf of Intermountain Gas Company (“Intermountain” or “the 7 Company”). 8 Please describe your education and experience. 9 A. I hold a Bachelor’s degree in Economics and Finance from Simmons College and a 10 Master’s degree in Economics from Boston University, with more than 25 years of 11 experience consulting to the energy industry. I have advised numerous energy and utility 12 clients on a wide range of financial and economic issues with primary concentrations in 13 valuation and utility rate matters. Many of these assignments have included the 14 determination of the cost of capital for valuation and ratemaking purposes. I have included 15 my resume and a summary of testimony that I have filed in other proceedings as Exhibit 16 No. 1. 17 PURPOSE AND OVERVIEW OF DIRECT TESTIMONY 18 Please describe the purpose of your testimony. 19 A. The purpose of my Direct Testimony is to present evidence and provide a recommendation 20 regarding the appropriate return on equity (“ROE”) for the Company and to assess the 21 reasonableness of its proposed capital structure for ratemaking purposes. 22 PAGE 3 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Are you sponsoring any schedules in support of your Direct Testimony? 1 A. Yes. My analysis and recommendations are supported by the data presented in Exhibit No. 2 2 through Exhibit No. 12, which were prepared by me or under my direction. 3 Please provide a brief overview of the analyses that led to your ROE recommendation. 4 A. I estimated the Company’s Cost of Equity (“COE”) by applying several traditional COE 5 estimation methodologies to a proxy group of comparable utilities including, Discounted 6 Cash Flow (“DCF”), Capital Asset Pricing Model (“CAPM”), Empirical CAPM 7 (“ECAPM”), and Bond Yield Risk Premium (“BYRP” or “Risk Premium”) analysis. My 8 recommendation also takes into consideration: (1) the Company’s small size, relative to 9 the proxy group, (2) the Company’s actual and anticipated capital expenditure 10 requirements, (3) the Company’s regulatory risk as compared with the proxy group, (4) the 11 Company’s service territory risk as compared to the proxy group, and (5) Flotation Costs. 12 Finally, I considered the Company’s capital structure as compared with the capital 13 structures of the proxy companies. 1 While I did not make any specific adjustments to the 14 ROE recommendation for any of these factors individually, I did take them into 15 consideration in aggregate when determining where the Company’s ROE falls within the 16 range of analytical results. 17 How is the remainder of your Direct Testimony organized? 18 A. Section II provides a summary of my analyses and conclusions. Section III reviews the 19 regulatory guidelines pertinent to the development of the cost of capital. Section IV 20 discusses current and projected capital market conditions and the effect of those conditions 21 1 The selection and purpose of developing a group of comparable companies will be discussed in detail in Section V of my Direct Testimony. PAGE 4 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS on the cost of equity. Section V explains the selection of a proxy group of natural gas 1 distribution utilities. Section VI describes the analyses and analytical basis for the 2 recommendation of an appropriate ROE for Intermountain. Section VII provides a 3 discussion of specific regulatory, business and financial risks that directly affect the ROE 4 to be authorized for the Company in this case. Section VIII addresses the Company’s 5 capital structure as compared with the capital structures of the utility operating company 6 subsidiaries of the proxy group companies. Section IX presents my conclusions and 7 recommendations. 8 SUMMARY OF ANALYSIS AND CONCLUSIONS 9 Please summarize the key factors considered in your analyses and upon which you 10 base your recommended ROE. 11 A. In developing my recommended ROE for Intermountain, I considered the following: 12  The United States Supreme Court’s Hope and Bluefield decisions that established the 13 standards for determining a fair and reasonable allowed ROE, including consistency of 14 the allowed return with the returns of other businesses having similar risk, adequacy of 15 the return to provide access to capital and support credit quality, and the requirement 16 that the result lead to just and reasonable rates.2 17  The effect of current and projected capital market conditions on ROE estimation 18 models and on investors’ return requirements. 19  The results of several analytical approaches that provide estimates of the Company’s 20 cost of equity. Because the Company’s required COE should be a forward-looking 21 2 Hope, 320 U.S. 591 (1944); Bluefield, 262 U.S. 679 (1923). PAGE 5 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS estimate, these analyses rely on forward-looking inputs and assumptions (e.g., 1 projected analyst growth rates in the DCF model, forecasted risk-free rate and Market 2 Risk Premium in the CAPM analysis, etc.) 3  The Company’s regulatory, business, financial and regulatory risks relative to the proxy 4 group of comparable companies, and the implications of those risks in determining an 5 appropriate ROE for the Company over the period during which rates will be in effect. 6 Please explain how you considered those factors. 7 A. I relied on the range of results produced by the Constant Growth DCF model, the CAPM 8 and ECAPM, and a Risk Premium analysis. As shown in Figure 1, these COE estimation 9 models produce a wide range of results. My conclusion as to the appropriate ROE for 10 Intermountain within that range of results is based on Intermountain’s business and 11 financial risk relative to the proxy group and my assessment of market conditions. 12 Although the companies in my proxy group are generally comparable to Intermountain, 13 each company is unique, and no two companies have the exact same business and financial 14 risk profiles. Accordingly, I considered the Company’s business, financial and regulatory 15 risk in aggregate relative to that of the proxy group companies when determining where 16 the Company’s ROE should fall within the reasonable range of analytical results to 17 appropriately account for any residual differences in risk. 18 Q. Please summarize the results of the COE estimation models that you considered to 19 establish the range of the COE for Intermountain. 20 A. Figure 1 summarizes the range of results produced by the Constant Growth DCF, CAPM, 21 ECAPM, and Bond Yield Risk Premium analyses. 22 PAGE 6 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Figure 1: Summary of Cost of Equity Analytical Results 1 2 As shown in Figure 1 (and in Exhibit No. 2), the range of results produced by the 3 COE estimation models is wide. While it is common to consider multiple models to 4 estimate the cost of equity, it is particularly important when the range of results varies 5 considerably across methodologies. As a result, my ROE recommendation considers the 6 range of results of the Constant Growth DCF model, as well as the results of the CAPM, 7 ECAPM, and Bond Yield Plus Risk Premium analyses. My ROE recommendation also 8 considers Intermountain’s company-specific risk factors and current and prospective 9 capital market conditions. 10 What is your conclusion regarding the appropriate authorized ROE for 11 Intermountain in this proceeding? 12 A. Based on the analytical results presented in Figure 1, my assessment of current and 13 anticipated capital market conditions, and the Company’s business, financial and 14 regulatory risk relative to proxy group companies, I conclude that a ROE in the range of 15 7.00%7.50%8.00%8.50%9.00%9.50%10.00%10.50%11.00%11.50%12.00%12.50%13.00% CAPM ECAPM Constant Growth DCF -Mean Constant Growth DCF -Median Risk Premium Recommended ROE Recommended ROE Range PAGE 7 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS 9.90 percent to 10.75 percent is reasonable. Considering underlying market conditions and 1 the business, financial and regulatory risk factors facing Intermountain, including the 2 Company’s small size compared to proxy group, significant capital expenditures and lack 3 of any mechanism to provide for recovery between rate cases, I believe an ROE of 10.30 4 percent is reasonable and appropriate. 5 Please summarize your analysis of the appropriate ratemaking capital structure for 6 the Company. 7 A. Based on the analysis presented in Section VIII of my testimony, I conclude that 8 Intermountain’s proposed 50.00 percent common equity ratio is reasonable. To determine 9 if Intermountain’s requested capital structure was reasonable, I reviewed the capital 10 structures of the utility subsidiaries of the proxy companies. As shown in Exhibit No. 12, 11 the results of that analysis demonstrate that the average equity ratios for the utility 12 operating companies of the proxy group range from 48.73 percent to 61.47 percent, with 13 an average of 56.41 percent. Comparing the recommended equity ratio to the proxy group 14 demonstrates that the Company’s requested equity ratio is well below the average equity 15 ratio for the utility operating subsidiaries of the proxy group companies. Further, the 16 Company’s proposed equity ratio is reasonable considering the negative effects from Tax 17 Cuts and Jobs Act of 2017 (“TCJA”) on coverage ratios and increased capital expenditures 18 on the cash flows and credit metrics of regulated utilities. 19 PAGE 8 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS REGULATORY GUIDELINES 1 Please describe the guiding principles to be used in establishing the cost of equity for 2 a regulated utility. 3 A. The United States Supreme Court’s precedent-setting Hope and Bluefield cases established 4 the standards for determining the fairness or reasonableness of a utility’s allowed ROE. 5 Among the standards established by the Court in those cases are: (1) consistency with other 6 businesses having similar or comparable risks; (2) adequacy of the return to support credit 7 quality and access to capital; and (3) the principle that the result reached, as opposed to the 8 methodology employed, is the controlling factor in arriving at just and reasonable rates.3 9 Has the Commission provided similar guidance in establishing the appropriate return 10 on common equity? 11 A. Yes. In Intermountain’s last rate case in 2016, the Commission findings were based on the 12 standards established in Hope and Bluefield: 13 The standards for determining a fair ROE for a regulated utility have been 14 framed by two decisions of the U.S. Supreme Court: Bluefield Water Works 15 & Improvement Co. v. Public Serv. Commission of West Virginia, 262 U.S. 16 679 (1923), and Federal Power Commission v. Hope Natural Gas Co., 320 17 U.S. 591 (1944). In these cases, the Court provided that the authorized ROE 18 should be: (1) sufficient to maintain financial integrity; (2) sufficient to 19 attract capital under reasonable terms; and (3) commensurate with returns 20 investors could earn by investing in other enterprises of comparable risk. In 21 line with these decisions, the Idaho Supreme Court has stated “that the 22 primary objective in ratemaking is to allow the utility to meet its legitimate 23 operating expenses, as well as to pay creditors, provide dividends to 24 shareholders, and maintain its financial integrity so that it might attract new 25 capital.” Application of Citizens Utilities Co., 112 Idaho 1061, 1067, 739 26 P.2d 360, 366 (1987).4 27 3 Hope, 320 U.S. 591 (1944); Bluefield, 262 U.S. 679 (1923). 4 In the Matter of the Application of Intermountain Gas Company to Change Its Rates and Charges for Natural Gas Service in the State of Idaho, Case No. INT-G-16-02, Order No. 33757, at 7-8 (April 28, 2017). PAGE 9 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS This guidance is in accordance with the Hope and Bluefield decisions and the 1 principles that I employed to estimate the ROE for Intermountain, including the principle 2 that an allowed rate of return must be sufficient to enable regulated companies like 3 Intermountain to attract capital on reasonable terms. Furthermore, the methodologies that 4 I have employed are consistent with the Commission’s recognition, as discussed below, 5 that it is important to consider other information beyond the results of the financial model 6 analysis to establish an ROE that is reasonable and reflects the investor-required return. 7 Why is it important for a utility to be allowed the opportunity to earn an ROE that is 8 adequate to attract capital at reasonable terms? 9 A. An ROE that is adequate to attract capital at reasonable terms enables the Company to 10 continue to provide safe, reliable natural gas service while maintaining its financial 11 integrity. That return should be commensurate with returns expected elsewhere in the 12 market for investments of equivalent risk. If it is not, debt and equity investors will seek 13 alternative investment opportunities for which the expected return reflects the perceived 14 risks, thereby inhibiting the Company’s ability to attract capital at reasonable cost. 15 Is a utility’s ability to attract capital also affected by the ROEs that are authorized 16 for other utilities? 17 A. Yes. Utilities compete directly for capital with other investments of similar risk, which 18 include other natural gas and electric utilities. Therefore, the ROE awarded to a utility 19 sends an important signal to investors regarding whether there is regulatory support for 20 financial integrity, dividends, growth, and fair compensation for business and financial 21 risk. The cost of capital represents an opportunity cost to investors. If higher returns are 22 available for other investments of comparable risk, investors have an incentive to direct 23 PAGE 10 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS their capital to those investments. Thus, an authorized ROE that is not in line with 1 authorized ROEs for other natural gas and electric utilities, on a risk adjusted basis, can 2 inhibit the utility’s ability to attract capital for investment in Idaho. 3 While Intermountain is committed to investing the required capital to provide safe 4 and reliable service, because Intermountain is a subsidiary of MDU Resources, the 5 Company competes with the other MDU Resources subsidiaries for discretionary 6 investment capital. In determining how to allocate its finite discretionary capital resources, 7 it would be reasonable for MDU Resources to consider the authorized ROE of each of its 8 subsidiaries. 9 What are your conclusions regarding these regulatory guidelines? 10 A. The ratemaking process is premised on the principle that a utility must have a reasonable 11 opportunity to recover the return of, and the market-required return on, its invested capital. 12 Because utility operations are capital-intensive, regulatory decisions should enable the 13 utility to attract capital at reasonable terms under a variety of economic and financial 14 market conditions; doing so balances the long-term interests of the utility and its customers. 15 The financial community carefully monitors the current and expected financial 16 condition of utility companies and the regulatory frameworks in which they operate. In that 17 respect, the regulatory framework is one of the most important factors in both debt and 18 equity investors’ assessments of risk. The Commission’s order in this proceeding, 19 therefore, should provide the Company with the opportunity to earn an ROE that is: (1) 20 adequate to attract capital at reasonable terms under a variety of economic and financial 21 market conditions over the period of time that its investment will be recovered; (2) 22 sufficient to reasonably ensure its financial integrity; and (3) commensurate with returns 23 PAGE 11 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS on investments in enterprises with similar risk. Providing the opportunity to earn a market-1 based cost of capital supports the financial integrity of the Company, which is in the interest 2 of both customers and shareholders. 3 What is the standard for setting the ROE in any jurisdiction? 4 A. The stand-alone ratemaking principle is the foundation of jurisdictional ratemaking. This 5 principle requires that the rates that are charged in any operating jurisdiction be for the 6 costs incurred in that jurisdiction. The stand-alone ratemaking principle ensures that 7 customers in each jurisdiction only pay for the costs of the service provided in that 8 jurisdiction, which is not influenced by the business operations in other operating 9 companies. In order to maintain this principle, the COE analysis is performed for an 10 individual operating company as a stand-alone entity. As such, I have evaluated the 11 investor-required return for Intermountain’s natural gas operations in Idaho. 12 CAPITAL MARKET CONDITIONS 13 Why is it important to analyze capital market conditions? 14 A. The COE estimation models rely on market data that are either specific to the proxy group, 15 in the case of the DCF model, or to the expectations of market risk, in the case of the 16 CAPM. The results of the COE estimation models can be affected by prevailing market 17 conditions at the time the analysis is performed. While the ROE that is established in a 18 rate proceeding is intended to be forward-looking, the analyst uses current and projected 19 market data, specifically stock prices, dividends, growth rates and interest rates, in the COE 20 estimation models to estimate the required return for the subject company. 21 As a result, it is important to consider the effect of these conditions on the COE 22 estimation models when determining the appropriate range and recommended ROE for a 23 PAGE 12 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS future period. If investors do not expect current market conditions to be sustained in the 1 future, it is possible that the COE estimation models will not provide an accurate estimate 2 of investors’ required return during that rate period. Therefore, it is very important to 3 consider projected market data to estimate the return for that forward-looking period. 4 What factors are affecting the cost of equity for regulated utilities in the current and 5 prospective capital markets? 6 A. The COE for regulated utility companies is being affected by several factors in the current 7 and prospective capital markets, including: 1) persistently high inflation, 2) changes in 8 monetary policy, and 3) rising long-term interest rates. These factors affect the 9 assumptions used in the COE estimation models. In this section, I discuss each of these 10 factors and how they affect the models used to estimate the cost of equity for regulated 11 utilities. 12 What effect do current and prospective market conditions have on the COE for 13 Intermountain? 14 A. As is discussed in more detail in the remainder of this section, the combination of 15 persistently high inflation, and the Federal Reserve’s changes in monetary policy, 16 contribute to an expectation of increased market risk and an increase in the cost of the 17 investor-required return. It is essential that these factors be considered in setting a forward-18 looking ROE. Inflation has recently been at some of the highest levels seen in 19 approximately 40 years. Interest rates, which have increased from the pandemic lows seen 20 in 2020 are expected to continue to increase in direct response to the Federal Reserve’s 21 monetary policy. Since there is a strong historical inverse correlation between interest rates 22 and the share prices of utility stocks (share prices of utility stocks typically fall when 23 PAGE 13 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS interest rates rise), it is reasonable to expect that investors’ required return for utility 1 companies will also continue to increase. Therefore, COE estimates based solely on 2 current market conditions will understate the COE required by investors during the future 3 period that the Company’s rates determined in this proceeding will be in effect. 4 A. Inflationary Expectations in Current and Project Capital Market Conditions 5 Has inflation increased significantly over the past year? 6 A. Yes. As shown in Figure 2, the YOY change in the Consumer Price Index (“CPI”) published 7 by the Bureau of Labor statistics has increased steadily since the beginning of 2021, rising 8 from 1.37 percent in January 2021. Since that time, and particularly since the start of 2022, 9 inflation has increased steadily, reaching a high of 9.0 percent YOY change in June 2022, 10 which was the largest 12-month increase since 1981 and significantly greater than any level 11 seen since January 2008, in October, CPI decreased to 7.76 percent, which is still at levels 12 not seen since the 1980s. 13 Figure 2: Consumer Price Index—YOY Percent Change January 2008–October 20225 14 15 5 Source: Bureau of Labor Statistics, shaded area indicates a recession. 0.5 0.502 0.504 0.506 0.508 0.51 -4.00% -2.00% 0.00% 2.00% 4.00% 6.00% 8.00% 10.00% Ja n - 0 8 Ap r - 0 8 Ju l - 0 8 Oc t - 0 8 Ja n - 0 9 Ap r - 0 9 Ju l - 0 9 Oc t - 0 9 Ja n - 1 0 Ap r - 1 0 Ju l - 1 0 Oc t - 1 0 Ja n - 1 1 Ap r - 1 1 Ju l - 1 1 Oc t - 1 1 Ja n - 1 2 Ap r - 1 2 Ju l - 1 2 Oc t - 1 2 Ja n - 1 3 Ap r - 1 3 Ju l - 1 3 Oc t - 1 3 Ja n - 1 4 Ap r - 1 4 Ju l - 1 4 Oc t - 1 4 Ja n - 1 5 Ap r - 1 5 Ju l - 1 5 Oc t - 1 5 Ja n - 1 6 Ap r - 1 6 Ju l - 1 6 Oc t - 1 6 Ja n - 1 7 Ap r - 1 7 Ju l - 1 7 Oc t - 1 7 Ja n - 1 8 Ap r - 1 8 Ju l - 1 8 Oc t - 1 8 Ja n - 1 9 Ap r - 1 9 Ju l - 1 9 Oc t - 1 9 Ja n - 2 0 Ap r - 2 0 Ju l - 2 0 Oc t - 2 0 Ja n - 2 1 Ap r - 2 1 Ju l - 2 1 Oc t - 2 1 Ja n - 2 2 Ap r - 2 2 Ju l - 2 2 Oc t - 2 2 Ye a r O v e r Y e a r % C h a n g e i n C P I PAGE 14 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS What are the expectations for inflation over the near-term? 1 A. The expectation is that inflation will remain elevated over the near-term. This expectation 2 is supported by recent comments of the Chair and Vice Chair of the Federal Reserve. For 3 example, in an interview with Bloomberg on November 14, 2022, Vice Chair Lael Brainard 4 noted that: 5 I think it will probably be appropriate soon to move to a slower pace of 6 increases. But I think what’s really important to emphasize -- we’ve 7 done a lot, but we have additional work to do both on raising rates and 8 sustaining restraint to bring inflation down to 2% over time. 9 We have raised rates very rapidly by nearly four percentage points over 10 about nine months and we’ve been reducing the balance sheet, and you can 11 see that in financial conditions. You can see it in inflation expectations, 12 which are quite well anchored. You can see it in interest-rate-sensitive 13 sectors. 14 But as we said last meeting, there are likely to be lags and it’s going to take 15 some time for that cumulative tightening to flow through. And so it makes 16 sense to move to a more deliberate and a more data-dependent pace as we 17 continue to make sure that there’s restraint that will bring inflation down 18 over time.6 19 Similarly, at the Federal Open Market Committee meeting in November 2022, 20 Chairman Powell indicated that: 21 My colleagues and I are strongly committed to bringing inflation back down 22 to our 2 percent goal. We have both the tools that we need and the resolve 23 it will take to restore price stability on behalf of American families and 24 businesses. Price stability is the responsibility of the Federal Reserve and 25 serves as the bedrock of our economy. Without price stability, the economy 26 does not work for anyone. In particular, without price stability, we will not 27 achieve a sustained period of strong labor market conditions that benefit all. 28 6 “Lael Brainard Talks Fed Interest Rates, Inflation, Crypto in Exclusive Interview.” Bloomberg.com, 14 Nov. 2022, https://www.bloomberg.com/news/articles/2022-11-14/fed-s-brainard-on-rates-inflation-crypto-labor-and- more-q-a. (emphasis added). PAGE 15 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Today, the FOMC raised our policy interest rate by 75 basis points, and we 1 continue to anticipate that ongoing increases will be appropriate. We are 2 moving our policy stance purposefully to a level that will be sufficiently 3 restrictive to return inflation to 2 percent. In addition, we are continuing the 4 process of significantly reducing the size of our balance sheet. Restoring 5 price stability will likely require maintaining a restrictive stance of policy 6 for some time. 7 … 8 At today’s meeting the Committee raised the target range for the federal 9 funds rate by 75 basis points. And we are continuing the process of 10 significantly reducing the size of our balance sheet, which plays an 11 important role in firming the stance of monetary policy. 12 With today’s action, we have raised interest rates by 3-3/4 percentage points 13 this year. We anticipate that ongoing increases in the target range for the 14 federal funds rate will be appropriate in order to attain a stance of monetary 15 policy that is sufficiently restrictive to return inflation to 2 percent over 16 time.7 17 Finally, Federal Reserve Governor Christopher Waller provided further support 18 that the Federal Reserve believes there is still significant progress that needs to be made to 19 bring inflation down to the Federal Reserve’s long-term target of 2 percent. At the UBS 20 Group AG conference on November 13, 2022, Federal Reserve Governor Waller stated: 21 “These rates are going to stay -- keep going up -- and they’re going to 22 stay high for a while until we see this inflation get down closer to our 23 target,” Waller said Monday at a UBS Group AG conference in Sydney. 24 “We’ve still got a ways to go. This isn’t ending in the next meeting or 25 two.”8 26 7 Transcript, Chair Powell, Press Conference, November 2, 2022. 8 Pandey, Swati. “Fed's Waller Says There's a 'Ways to Go' before Rate Hikes Done.” Bloomberg.com, Bloomberg, 13 Nov. 2022, https://www.bloomberg.com/news/articles/2022-11-13/fed-s-waller-says-there-s-a-ways-to-go- before-rate-hikes-done.

The use of Monetary Policy to Address Inflation 1 What policy actions has the Federal Reserve enacted to respond to increased inflation? 2 A. The dramatic increase in inflation has prompted the Federal Reserve to pursue an aggressive 3 normalization of monetary policy, removing the accommodative policy programs used to 4 mitigate the economic effects of COVID-19. As of the November 2, 2022 meeting, the 5 Federal Reserve has taken the following actions: 6  Completed its taper of Treasury bond and mortgage-backed securities purchases9; 7  Increased the target federal funds rate beginning in March 2022 through a series of six 8 increases from 0.00 – 0.25 percent to 3.75 percent to 4.00 percent.10 9  Anticipates the need to bring the Fed Funds rate to a restrictive level and keep it there 10 for some time in order to achieve its goals of maximum employment at the inflation 11 rate of 2 percent over the long-run;11 12  Began reducing its holdings of Treasury and mortgage-backed securities on June 1, 13 2022.12 The Federal Reserve is reducing the size of its balance sheet by only 14 reinvesting principle payments on owned securities after the total amount of payments 15 received exceeds a defined cap. For Treasury Securities, the cap is set at $60 billion 16 per month. The cap for mortgage-backed securities is set at $35 billion per month.13 17 9 Source: Federal Reserve Bank of New York, https://www.newyorkfed.org/markets/domestic-market- operations/monetary-policy-implementation/treasury-securities/treasury-securities-operational-details#monthly- details. 10 Federal Reserve, Press Releases, March 16, 2022, May 4, 2022, June 15, 2022, September 22, 2022 and November 2, 2022 11 Transcript, Chair Powell, Press Conference, September 21, 2022. 12 Source: Federal Reserve, Press Release, (May 4, 2022). 13 Source: Federal Reserve, Plans for Reducing the Size of the Federal Reserve's Balance Sheet, Press Release, (May 4, 2022).

The Effect of Inflation and Monetary Policy on Interest Rates and the 1 Investor-Required Return 2 What effect will inflation and Federal Reserve’s normalization of monetary policy 3 have on long-term interest rates? 4 A. Inflation and the Federal Reserve’s normalization of monetary policy will likely result in 5 increases in long-term interest rates. Specifically, inflation reduces the purchasing power 6 of the future interest payments an investor expects to receive over the duration of the 7 bond. This risk increases the longer the duration of the bond. As a result, if investors 8 expect increased levels of inflation, they will require higher yields to compensate for the 9 increased risk of inflation, which means interest rates will increase. 10 Have the yields on long-term government bonds increased in response to inflation and 11 the Federal Reserve’s normalization of monetary policy? 12 A. Yes, they have. As shown in Figure 3, since the Federal Reserve’s December 2021 13 meeting, the yield on 10-year Treasury bond has more than doubled, increasing from 1.47 14 percent on December 15, 2021 to 4.10 percent on October 31, 2022. The increase is due 15 to the Federal Reserve’s announcements at each of the meetings since December 2021, 16 and the continued increased levels of inflation that are now expected to persist much 17 longer than the Federal Reserve and investors had originally projected. 18 PAGE 18 OF 79 A.

No. While FOMC participants have reduced their projections for economic activity for 4 real GDP growth of 0.2 percent in 2022 and 1.2 percent in 202315, which is well below 5 the median estimate for the longer-run normal GDP growth rate, the Fed has highlighted 6 that the labor market continues to be extremely tight.

Expected Performance of Utility Stocks and the Investor-Required Return 3 on Utility Investments 4 Are utility share prices correlated to changes in the yields on long-term government 5 bonds? 6 A. Yes. Interest rates and utility share prices are inversely correlated which means, for 7 example, that an increase in interest rates will result in a decline in the share prices of 8 utilities. For example, Goldman Sachs and Deutsche Bank examined the sensitivity of 9 share prices of different industries to changes in interest rates over the past five years. 10 Both Goldman Sachs and Deutsche Bank found that utilities had one of the strongest 11 negative relationships with bond yields (i.e., increases in bond yields resulted in the 12 decline of utility share prices).18 13 How do equity analysts expect the utilities sector to perform in an increasing interest 14 rate environment? 15 A. Equity analysts project that utilities will underperform the broader market as interest rates 16 increase. Fidelity recently classified the utility sector as underweight19 and Morningstar 17 recently noted that a long as inflation persists the utility sector will underperform.20 18 Specifically, Morningstar noted that: 19 17 Ibid. 18 Lee, Justina. “Wall Street Is Rethinking the Treasury Threat to Big Tech Stocks.” Bloomberg.com, 11 Mar. 2021, www.bloomberg.com/news/articles/2021-03-11/wall-street-is-rethinking-the-treasury-threat-to-big-tech-stocks. 19 Fidelity, “Fourth Quarter 2022, Investment Research Update,” October 26, 2022. 20 Miller, Travis, “As Long as Inflation Worries Persist, We Expect Utilities to Underperform: Renewable energy continues to be a long-term boon for the sector,” July 6, 2022. PAGE 20 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS [a]s long as inflation remains the market’s top concern, we expect utilities 1 to underperform. Utilities are the most sensitive to inflation because of their 2 mostly fixed revenue, large capital investment budgets, and borrowing 3 needs. We think long-term investors who want utilities in their portfolios 4 should focus on those in constructive regulatory environments with the most 5 protection from inflation.21 6 Additionally, the Wall Street Journal (“WSJ”) recently noted in an article published 7 on October 18, 2022 that the S&P Utilities Index was down 14 percent over the past month. 8 The WSJ attributed the decline in the S&P Utilities Index to the recent increase in long-9 term treasury yields: 10 A big draw of utility stocks has become less attractive as interest rates have 11 climbed. Utility stocks are known for their sizable dividends, offering 12 investors a regular stream of income. Companies in the S&P 500 utilities 13 sector offer a dividend yield of 3.3%, among the highest payout percentages 14 in the index, according to FactSet. 15 But the outsize dividends of utility stocks are no match for climbing bond 16 yields. The yield on the benchmark 10-year Treasury note finished above 17 4% on Monday for a second consecutive session. Friday marked the 10-year 18 yield’s first close above the 4% level since 2008 and 11 straight weeks of 19 gains. Treasurys are viewed as essentially risk-free if held to maturity. 20 “The 10-year is repricing everything. I’ve got something that’s even safer 21 and yields even more," said Kevin Barry, chief investment officer at 22 Summit Financial, comparing Treasurys and utility stocks.22 23 Similarly, Barron’s recently noted that the decline in share prices can be attributed 24 to the relatively high valuations and low dividend yields of utilities as compared to other 25 asset classes such as Treasuries.23 According to Barron’s, even after the recent decline in 26 21 Ibid. 22 Miao, Hannah, “Utility Stock stumble as treasury yields climb,” The Wall Street Journal, October 18, 2022. 23 Sonenshine, Jacob, “Utilities Stocks Have Fallen off a Cliff. They Just Got Downgraded, Too.” Barron’s, October 17, 2022. PAGE 21 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS share prices, the Utilities Select ETF was yielding 2.85 percent, which is a yield that will 1 not “lure in buyers when the ultrasafe 10-year Treasury note yields close to 4%.”24 2 Therefore, Barron’s currently recommends not buying utility stocks. 3 Have you reviewed any market indicators that may imply that utilities will 4 underperform over the near-term? 5 A. Yes, I have. As discussed above, the utility sector is considered a “bond proxy” or a 6 sector that investors view as a “safe haven” alternative to bonds, and changes in utility 7 stock prices are therefore inversely related to changes in interest rates. For example, the 8 utility sector tends to perform well when interest rates are low since the dividend yields 9 for utilities offer investors the prospect of higher returns when compared to the yields on 10 long-term government bonds. Conversely, the utility sector underperforms as the yields 11 on long-term government bonds increase and the spread between the dividend yields on 12 utility stocks and the yields on long-term government bonds decreases. Therefore, I 13 examined the difference (“yield spread”) between the dividend yields of utility stocks and 14 the yields on long-term government bonds from January 2010 through October 2022. I 15 selected the dividend yield on the S&P Utilities Index as the measure of the dividend 16 yields for the utility sector and the yield on the 10-year Treasury Bond as the estimate of 17 the yield on long-term government bonds. 18 As shown in Figure 4, the yield spread as of October 31, 2022, was -0.99 percent 19 indicating that the yield on the 10-year Treasury Bond has exceeded the dividend yield for 20 the S&P Utilities Index. Furthermore, the current yield spread of -0.99 percent is well 21 24 Ibid. PAGE 22 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS below the long-term average since January 2010 of 1.39 percent. Given that the yield 1 spread is currently well below the long-term average as well as the expectation that interest 2 rates will continue to increase, it is reasonable to conclude that utility sector will most likely 3 underperform over the near-term. This is because investors that purchased utility stocks as 4 an alternative to the lower yields on long-term government bonds would otherwise be 5 inclined to rotate back into government bonds, particularly as the yields on long-term 6 government bonds continue to increase, thus resulting in a decrease in the share prices of 7 utilities. 8 Figure 4: Yield Spread between the Dividend Yield on the S&P Utilities Index and the 9 Yield on the 10-year Treasury Bond – January 2012 – October 202225 10 11 What is the significance of the inverse relationship between interest rates and utility 12 share prices in the current market? 13 A. As discussed above, the Federal Reserve is currently normalizing monetary policy in 14 response to inflation which actions are expected to increase long-term government bond 15 25 S&P Capital IQ Pro and Bloomberg Professional. -2.00% -1.00% 0.00% 1.00% 2.00% 3.00% 4.00% Yi e l d S p r e a d PAGE 23 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS yields. If interest rates increase as expected, then the share prices of utilities will decline. 1 If the prices of utility stocks decline, then the DCF model, which relies on historical 2 averages of share prices, is likely to understate the cost of equity. For example, Figure 5, 3 below summarizes the effect of price on the dividend yield in the Constant Growth DCF 4 model. 5 Figure 5: The Effect of a Decline in Stock Prices 6 on the Constant Growth DCF Model 7 A decline in stock prices will increase the dividend yields and thus the estimate of 8 the ROE produced by the Constant Growth DCF model. Therefore, this expected change 9 in market conditions supports consideration of the range of ROE results produced by the 10 mean to mean-high DCF results since the mean DCF results would likely understate the 11 cost of equity during the period that the Company’s rates will be in effect. Moreover, 12 prospective market conditions warrant consideration of other ROE estimation models such 13 as the CAPM and ECAPM, which may better reflect expected market conditions. For 14 example, two out of three inputs to the CAPM (i.e., the market risk premium and risk-free 15 rate) are forward-looking. 16 PAGE 24 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Q. Have regulatory commissions acknowledged that the DCF model might understate 1 the COE given the current capital market conditions of high inflation and increasing 2 interest rates? 3 A. Yes. For example, in its May 2022 decision in establishing the cost of equity for Aqua 4 Pennsylvania, Inc., the Pennsylvania Public Utility Commission (“PPUC”) specifically 5 concluded that the current capital market conditions of high inflation and increasing 6 interest rates has resulted in the DCF model understating the utility cost of equity, and 7 that weight should be placed on risk premium models, such as the CAPM, in the 8 determination of the ROE: 9 To help control rising inflation, the Federal Open Market Committee has 10 signaled that it is ending its policies designed to maintain low interest rates. 11 Aqua Exc. at 9. Because the DCF model does not directly account for 12 interest rates, consequently, it is slow to respond to interest rate changes. 13 However, I&E’s CAPM model uses forecasted yields on ten-year Treasury 14 bonds, and accordingly, its methodology captures forward looking changes 15 in interest rates. 16 Therefore, our methodology for determining Aqua’s ROE shall utilize both 17 I&E’s DCF and CAPM methodologies. As noted above, the Commission 18 recognizes the importance of informed judgment and information provided 19 by other ROE models. In the 2012 PPL Order, the Commission considered 20 PPL’s CAPM and RP methods, tempered by informed judgment, instead of 21 DCF-only results. We conclude that methodologies other than the DCF can 22 be used as a check upon the reasonableness of the DCF derived ROE 23 calculation. Historically, we have relied primarily upon the DCF 24 methodology in arriving at ROE determinations and have utilized the results 25 of the CAPM as a check upon the reasonableness of the DCF derived equity 26 return. As such, where evidence based on other methods suggests that the 27 DCF-only results may understate the utility’s ROE, we will consider those 28 other methods, to some degree, in determining the appropriate range of 29 reasonableness for our equity return determination. In light of the above, we 30 PAGE 25 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS shall determine an appropriate ROE for Aqua using informed judgement 1 based on I&E’s DCF and CAPM methodologies.26 2 ….. 3 We have previously determined, above, that we shall utilize I&E’s DCF and 4 CAPM methodologies. I&E’s DCF and CAPM produce a range of 5 reasonableness for the ROE in this proceeding from 8.90% [DCF] to 9.89% 6 [CAPM]. Based upon our informed judgment, which includes consideration 7 of a variety of factors, including increasing inflation leading to increases in 8 interest rates and capital costs since the rate filing, we determine that a base 9 ROE of 9.75% is reasonable and appropriate for Aqua.27 10 E. Conclusion 11 What are your conclusions regarding the effect of current market conditions on the 12 cost of equity for the Company? 13 A. Over the near-term, investors expect long-term interest rates to increase in response to 14 continued elevated levels of inflation and the Federal Reserve’s normalization of 15 monetary policy. Because the share prices of utilities are inversely correlated to interest 16 rates, an increase in long-term government bond yields will likely result in a decline in 17 utility share prices, which is the reason a number of equity analysts expect the utility 18 sector to underperform over the near-term. The expected underperformance of utilities 19 means that DCF models using recent historical data likely underestimate investors’ 20 required return over the period that rates will be in effect. This change in market 21 conditions also supports the use of other ROE estimation models such as the CAPM and 22 the ECAPM, which may more directly reflect expected market conditions. 23 26 Penn.

BULKLEY, DI INTERMOUNTAIN GAS PROXY GROUP SELECTION 1 Please provide a brief profile of Intermountain. 2 A. Intermountain Gas Company is a natural gas distribution company that is a wholly owned 3 subsidiary of MDU Resources Group, Inc. As of September 2022, Intermountain served 4 approximately 404,770 retail customers and 109 transportation customers. Intermountain 5 accounted for 27.00 percent of the natural gas distribution operating sales revenues for 6 Intermountain’s parent, MDU Resources, in 2021, while Washington (29.00 percent), 7 North Dakota (15.00 percent), Montana (10.00 percent), Oregon (8.00 percent), South 8 Dakota (6.00 percent), Minnesota (3.00 percent) and Wyoming (2.00 percent) accounted 9 for the other 73.00 percent of retail gas distribution operating sales revenues.28 MDU 10 Resources currently has long-term issuer ratings of BBB+/Stable from Standard & Poor’s 11 and BBB+/Stable from Fitch.29 12 Why have you used a group of proxy companies to estimate the COE for 13 Intermountain? 14 A. In this proceeding, we focus on estimating the COE for a natural gas utility company that 15 is not itself publicly traded. Because the COE is a market-based concept and because 16 Intermountain’s operations do not make up the entirety of a publicly traded entity, it is 17 necessary to establish a group of companies that is both publicly traded and comparable 18 to the Company in certain fundamental business and financial respects to serve as its 19 “proxy” in the COE estimation process. 20 28 MDU Resources, 2021 Form 10-K, at 15. 29 Source: S&P Capital IQ Pro, (September 15, 2022) and FitchRatings. PAGE 27 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Even if Intermountain was a publicly traded entity, it is possible that transitory 1 events could bias its market value over a given period. A significant benefit of using a 2 proxy group is that it moderates the effects of unusual events that may be associated with 3 any one company. The proxy companies used in my analyses all possess a set of operating 4 and risk characteristics that are substantially comparable to the Company, and thus provide 5 a reasonable basis to derive and estimate the appropriate ROE for Intermountain. 6 How did you select the companies included in your proxy group? 7 A. I began with the group of 10 publicly traded companies that Value Line classifies as 8 Natural Gas Distribution Utilities and applied the following screening criteria to select a 9 group of risk-comparable companies that: 10  pay consistent quarterly cash dividends, because companies that do not 11 cannot be analyzed using the Constant Growth DCF model; 12  have investment grade long-term issuer ratings from S&P and/or Moody’s; 13  are covered by at least two utility industry analysts; 14  have positive long-term earnings growth forecasts from at least two utility 15 industry equity analysts; 16  derive more than 60.00 percent of their total operating income from 17 regulated operations; 18  derive more than 60.00 percent of regulated operating income from gas 19 distribution operations; and 20  were not parties to a merger or transformative transaction during the 21 analytical periods relied on. 22 What is the composition of your proxy group? 23 A. The screening criteria discussed above resulted in a proxy group consisting of the 24 companies shown in Figure 6 below. 25 PAGE 28 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Figure 6: Natural Gas Utility Proxy Group 1 Company Ticker Atmos Energy Corporation ATO New Jersey Resources NJR NiSource NI Northwest Natural Gas Company NWN ONE Gas, Inc. OGS Spire, Inc. SR 2 Do your screening criteria result in a proxy group that is risk comparable to 3 Intermountain? 4 A. Yes, they do. The overall purpose of developing a set of screening criteria is to select a 5 proxy group of companies that align with the financial and operational characteristics of 6 Intermountain and that investors would view as comparable to the Company. I developed 7 the screens and thresholds for each screen based on judgment with the intention of 8 balancing the need to maintain a proxy group that is of sufficient size with establishing a 9 proxy group of companies that are comparable in business and financial risk to 10 Intermountain. This resulted in the group of six companies shown in Figure 6, which 11 have business and financial risks that are comparable to Intermountain. 12 COST OF EQUITY ESTIMATION 13 Please briefly discuss the ROE in the context of the regulated rate of return (“ROR”). 14 A. The ROE is the cost rate applied to the equity capital in the ROR. The ROR for a 15 regulated utility is the weighted average cost of capital, in which the costs of the 16 individual sources of capital are weighted by their respective proportion (i.e. book values) 17 in the utility’s capital structure. While the costs of debt and preferred stock can be 18 PAGE 29 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS directly observed, the COE is market-based and, therefore, must be estimated based on 1 observable market data. 2 How is the required COE determined? 3 A. The required COE is estimated by using analytical techniques that rely on market-based 4 data to quantify investor expectations regarding equity returns, adjusted for certain 5 incremental costs and risks. Informed judgment is then applied to determine where the 6 company’s COE falls within the range of results produced by multiple analytical 7 techniques. The key consideration in determining the COE is to ensure that the 8 methodologies employed reasonably reflect investors’ views of the financial markets in 9 general, as well as the subject company (in the context of the proxy group), in particular. 10 What methods did you use to establish your recommended ROE in this proceeding 11 ROE? 12 A. I considered the results of the Constant Growth DCF model, the CAPM, the ECAPM, 13 and a Bond Yield Plus Risk Premium analysis. As discussed in more detail below, a 14 reasonable ROE estimate appropriately considers alternative methodologies and the 15 reasonableness of their individual and collective results. 16 A. Importance of Multiple Analytical Approaches 17 Why is it important to use more than one analytical approach? 18 A. Because the COE is not directly observable, it must be estimated based on both 19 quantitative and qualitative information. When faced with the task of estimating the COE, 20 analysts and investors are inclined to gather and evaluate as much relevant data as 21 reasonably can be analyzed. Several models have been developed to estimate the COE, 22 and I use multiple approaches to estimate the COE. As a practical matter, however, all the 23 PAGE 30 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS models available for estimating the COE are subject to limiting assumptions or other 1 methodological constraints. Consequently, many well-regarded finance texts recommend 2 using multiple approaches when estimating the COE. For example, Copeland, Koller, and 3 Murrin30 suggest using the CAPM and Arbitrage Pricing Theory model, while Brigham 4 and Gapenski31 recommend the CAPM, DCF, and Bond Yield Plus Risk Premium 5 approaches. 6 Do current market conditions increase the importance of using more than one 7 analytical approach? 8 A. Yes. As previously discussed, interest rates have increased substantially from the lows 9 during the COVID-19 pandemic, and upward pressure is expected to continue as the 10 Federal Reserve continues to combat persistently high inflation. Given the inverse 11 relationship between interest rates and utility share prices, the dividend yields of utilities 12 are expected to increase over the near-term. Therefore, the current low dividend yields 13 for utilities result in DCF cost of equity estimates that are understating the forward-14 looking cost of equity. The CAPM and Bond Yield Plus Risk Premium method offer 15 some balance through the use of projected interest rates. Therefore, it is important to use 16 multiple analytical approaches to ensure that the COE results reflect the market 17 conditions that are expected during the period that Company's rates will be in effect. 18 Given the expectation that interest rates will increase, it is important to moderate the 19 impact that the current lower interest rates are having on the COE estimates, especially 20 30 Tom Copeland, Tim Koller and Jack Murrin, Valuation: Measuring and Managing the Value of Companies, 3rd Ed.

BULKLEY, DI INTERMOUNTAIN GAS the DCF analysis, and where possible consider using projected market data in the models 1 to estimate the return for the forward-looking period. 2 Has the Commission made similar findings regarding the reliance on multiple 3 models? 4 A. Yes. It is my understanding that in determining the authorized ROE for a company, the 5 Commission has considered the evidence presented by the parties in the rate case, which 6 has included a range of COE estimation methodologies such as the DCF, CAPM, Risk 7 Premium and Comparable Earnings.32 8 Are you aware of any other regulatory commissions that have recognized the 9 importance of considering the results of multiple models? 10 A. Yes, regulatory commissions routinely consider the results of multiple COE estimation 11 methodologies such as the DCF, CAPM, ECAPM and Risk Premium in determining the 12 authorized ROE for utilities in jurisdictional rate proceedings, including the Iowa Utilities 13 Board (“IUB”),33 the Minnesota Public Utilities Commission (“Minnesota PUC”),34 the 14 Michigan Public Service Commission (“Michigan PSC”),35 the Washington Utilities and 15 Transportation Commission (“Washington UTC”),36 and the New Jersey Board of Public 16 32 In the Matter of the Application of Intermountain Gas Company to Change Its Rates and Charges for Natural Gas Service in the State of Idaho, Case No. INT-G-16-02, Order No. 33757, at 7-9 (April 28, 2017). 33 Docket RPU-2021-0002, Order Approving Settlement, Approving Compliance Filings, and Granting Confidential Treatment Requests; at 10; Docket RPU-2019-0002, Order Regarding Settlement and Requiring Compliance Filings; at 12-13 34 Docket No. G011/GR-17-563, Findings of Fact, Conclusions and Order, at 27; Docket No. E015/GR-16-664, Findings of Fact, Conclusions and Order, at 60-61 35 Michigan Public Service Commission Order, DTE Gas Company, Case No. U-18999, at 45-47 (Sept. 13, 2018). 36 Wash.

BULKLEY, DI INTERMOUNTAIN GAS Utilities (“NJBPU”).37 For example, the Washington UTC has repeatedly emphasized 1 that it “places value on each of the methodologies used to calculate the cost of equity and 2 does not find it appropriate to select a single method as being the most accurate or 3 instructive.”38 The Washington UTC has also explained that “[f]inancial circumstances 4 are constantly shifting and changing, and we welcome a robust and diverse record of 5 evidence based on a variety of analytics and cost of capital methodologies.”39 6 Additionally, in its recent order for DTE Gas Company (“DTE Gas”) in Case No. 7 U-18999, the Michigan PSC considered the results of each of the models presented by the 8 ROE witnesses which included the DCF, CAPM, ECAPM and Risk Premium in the 9 determination of the authorized ROE.40 The Commission also considered authorized ROEs 10 in other states, increased volatility in capital markets and the company-specific business 11 risks of DTE Gas. 12 B. Constant Growth DCF Model 13 Please describe the DCF approach. 14 A. The DCF approach is based on the theory that a stock’s current price represents the 15 present value of all expected future cash flows. In its most general form, the DCF model 16 is expressed as follows: 17 P0 =D1 (1+k)+D2 (1+k)2 +⋯+D∞ (1+k)∞ [1] 18 37 NJBPU Docket No. ER12111052, OAL Docket No. PUC16310-12, Order Adopting Initial Decision with Modifications and Clarifications, at 71 (March 18, 2015). 38 Wash. Utils. & Transp. Comm’n v. PacifiCorp, Docket UE-130043, Order 05, n. 89 (Dec. 4, 2013). 39 Wash. Utils. & Transp. Comm’n v.

BULKLEY, DI INTERMOUNTAIN GAS Where P0 represents the current stock price, D1…D∞ are all expected future 1 dividends, and k is the discount rate, or required ROE. Equation [1] is a standard present 2 value calculation that can be simplified and rearranged into the following form: 3 k =D0(1+g) P0 +g [2] 4 Equation [2] is often referred to as the Constant Growth DCF model in which the 5 first term is the expected dividend yield and the second term is the expected long-term 6 growth rate. 7 What assumptions are required for the Constant Growth DCF model? 8 A. The Constant Growth DCF model requires the following four assumptions: (1) a constant 9 growth rate for earnings and dividends; (2) a stable dividend payout ratio; (3) a constant 10 price-to-earnings (“P/E”) ratio; and (4) a discount rate greater than the expected growth 11 rate. To the extent that any of these assumptions are violated, considered judgment and/or 12 specific adjustments should be applied to the results. 13 What market data did you use to calculate the dividend yield in your Constant 14 Growth DCF model? 15 A. The dividend yield in my Constant Growth DCF model is based on the proxy companies’ 16 current annualized dividend and average closing stock prices over the 30-, 90-, and 180-17 trading days ended October 31, 2022. 18 Why did you use 30-, 90-, and 180-day averaging periods? 19 A. In my Constant Growth DCF model, I use an average of recent trading days to calculate 20 the term P0 in the DCF model to reflect current market data while also ensuring that the 21 ROE is not skewed by anomalous events that may affect stock prices on any given 22 trading day. However, as discussed above, recent market data is not representative of 23 PAGE 34 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS expected market conditions over the long-term. Therefore, the results of my Constant 1 Growth DCF model using historical data may underestimate the forward-looking COE. 2 Did you make any adjustments to the dividend yield to account for periodic growth 3 in dividends? 4 A. Yes, I did. Because utility companies tend to increase their quarterly dividends at 5 different times throughout the year, it is reasonable to assume that dividend increases will 6 be evenly distributed over calendar quarters. Given that assumption, it is reasonable to 7 apply one-half of the expected annual dividend growth rate for purposes of calculating 8 the expected dividend yield component of the DCF model. This adjustment ensures that 9 the expected first-year dividend yield is, on average, representative of the coming twelve-10 month period, and does not overstate the aggregated dividends to be paid during that 11 time. 12 Why is it important to select appropriate measures of long-term growth in applying 13 the DCF model? 14 A. In its Constant Growth form, the DCF model (i.e., Equation [2]) assumes a single growth 15 estimate in perpetuity. To reduce the long-term growth rate to a single measure, one must 16 assume that the payout ratio remains constant and that earnings per share, dividends per 17 share and book value per share all grow at the same constant rate. Over the long run, 18 however, dividend growth can only be sustained by earnings growth. Therefore, it is 19 important to incorporate a variety of sources of long-term earnings growth rates into the 20 Constant Growth DCF model. 21 PAGE 35 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Which sources of long-term earnings growth rates did you use? 1 A. My Constant Growth DCF model incorporates three commonly referenced sources of 2 long-term earnings growth rates: (1) Zacks Investment Research; (2) Yahoo! Finance; 3 and (3) Value Line Investment Survey. 4 How did you calculate the range of results for the Constant Growth DCF Models? 5 A. I calculated the low result for my DCF model using the minimum growth rate (i.e., the 6 lowest of the Value Line, Yahoo! Finance, and Zacks earnings growth rates) for each of 7 the proxy group companies. Thus, the low result reflects the minimum DCF result for the 8 proxy group. I used a similar approach to calculate the high results, using the highest 9 growth rate for each proxy group company. 10 What were the results of your Constant Growth DCF analyses? 11 A. Figure 7 (see also Exhibit No. 3) summarizes the results of my DCF analyses. As shown 12 in Figure 7 13 A. Figure 7, the median and mean DCF results range from 9.56 percent to 9.91 percent, and 14 the median high and mean high results are in the range of 10.66 percent to 11.41 percent. 15 While I also summarize the low DCF results, given the expected underperformance of 16 utility stocks and thus the likelihood that the DCF model is understating the COE, I do 17 not believe it is appropriate to consider the low DCF results at this time. 18 PAGE 36 OF 79 A.

As discussed previously, one primary assumption of the Constant Growth DCF model is 3 a constant P/E ratio. That assumption is heavily influenced by the market price of utility 4 stocks. Since utility stocks are expected to underperform in the broader market over the 5 near-term as interest rates increase, it is important to consider the results of the DCF 6 models with caution. This means that the results of the current DCF models are below 7 where they would otherwise be under more normal market conditions. Therefore, while I 8 have given weight to the results of the Constant Growth DCF model, my 9 recommendation also gives weight to the results of other COE estimation models. 10 C. CAPM Analysis 11 Please briefly describe the CAPM. 12 A. The CAPM is a risk premium approach that estimates the COE for a given security as a 13 function of a risk-free return plus a risk premium to compensate investors for the non-14 diversifiable, systematic risk of that security. Systematic risk is the risk inherent in the 15 entire market or market segment—which cannot be diversified away using a portfolio of 16 PAGE 37 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS assets. Unsystematic risk is the risk of a specific company that can, theoretically, be 1 mitigated through portfolio diversification. 2 The CAPM is defined by four components, each of which must theoretically be a 3 forward-looking estimate: 4 Ke =rf +β(rm-rf) [3] 5 Where: 6 Ke = the required market COE; 7 β = Beta coefficient of an individual security; 8 rf = the risk-free rate of return; and 9 rm = the required return on the market. 10 In this specification, the term (rm – rf) represents the market risk premium. 11 According to the theory underlying the CAPM, because unsystematic risk can be 12 diversified away, investors should only be concerned with systematic or non-diversifiable 13 risk. Systematic risk is measured by Beta. Beta is a measure of the volatility of a security 14 as compared to the market as a whole. Beta is defined a: 15 16 PAGE 38 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS β = Covariance(re, rm) [4] Variance(rm) The variance of the market return (i.e., Variance (rm)) is a measure of the 1 uncertainty of the general market, and the covariance between the return on a specific 2 security and the general market (i.e., Covariance (re, rm)) reflects the extent to which the 3 return on that security will respond to a given change in the general market return. Thus, 4 Beta represents the risk of the security relative to the general market. 5 What risk-free rate did you use in your CAPM analysis? 6 A. I relied on three sources for my estimate of the risk-free rate: (1) the current 30-day 7 average yield on 30-year U.S. Treasury bonds, which is 3.92 percent;41 (2) the average 8 projected 30-year U.S. Treasury bond yield for the first quarter of 2023 through the first 9 quarter of 2024, which is 4.00 percent;42 and (3) the average projected 30-year U.S. 10 Treasury bond yield for 2024 through 2028, which is 3.80 percent.43 11 What Beta coefficients did you use in your CAPM analysis? 12 A. As shown Exhibit No. 4, I used the Beta coefficients for the proxy group companies as 13 reported by Bloomberg and Value Line. The Beta coefficients reported by Bloomberg 14 were calculated using ten years of weekly returns relative to the S&P 500 Index. Value 15 Line’s calculation is based on five years of weekly returns relative to the New York 16 Stock Exchange Composite Index. 17 Additionally, as shown in Exhibit No. 5, I also considered an additional CAPM 18 analysis which relies on the long-term average utility Beta coefficient for the companies in 19 41 Bloomberg Professional as of October 31, 2022. 42 Blue Chip Financial Forecasts, Vol. 41, No. 11, at 2 (November 1, 2022). 43 Blue Chip Financial Forecasts, Vol. 41, No. 6, at 14 (June 1, 2022). PAGE 39 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS my proxy group. As shown in Exhibit No. 5, the long-term average utility Beta coefficient 1 was calculated as an average of the Value Line Beta coefficients for the companies in my 2 proxy group from 2013 through 2021. 3 How did you estimate the market risk premium in the CAPM? 4 A. I estimated the Market Risk Premium (“MRP”) as the difference between the implied 5 expected equity market return and the risk-free rate. As shown in Exhibit No. 6, the 6 expected return on the S&P 500 Index is calculated using the Constant Growth DCF 7 model discussed earlier in my testimony for the companies in the S&P 500 Index. In my 8 calculation of the market return, I included companies in the S&P 500 that: 1) had either 9 a dividend yield or Value Line long-term earnings projections; and 2) had a Value Line 10 long-term earnings growth rate that was greater than 0 percent and less than or equal to 11 20 percent. Based on an estimated market capitalization-weighted dividend yield of 1.84 12 percent and a weighted long-term growth rate of 10.82 percent, the estimated required 13 market return for the S&P 500 Index is 12.76 percent. 14 How does the current expected market return of 12.76 percent compare to observed 15 historical market returns? 16 A. Given the range of annual equity returns that have been observed over the past century 17 (shown in Figure 8), a current expected return of 12.76 percent is not unreasonable. In 50 18 out of the past 96 years (or roughly 52 percent of observations), the realized equity return 19 was at least 12.76 percent or greater. 20 PAGE 40 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Figure 8: Realized U.S. equity market returns (1926-2021) 44 1 2 Did you consider another form of the CAPM in your analysis? 3 A. Yes. I have also considered the results of an ECAPM or alternatively referred to as the 4 Zero-Beta CAPM45 in estimating the COE for Intermountain. The ECAPM calculates the 5 product of the adjusted Beta coefficient and the market risk premium and applies a 6 weight of 75.00 percent to that result. The model then applies a 25.00 percent weight to 7 the market risk premium, without any effect from the Beta coefficient. The results of the 8 two calculations are summed, along with the risk-free rate, to produce the ECAPM result, 9 as noted in Equation [5] below: 10 44 Depicts total annual returns on large company stocks, as reported in the 2022 Kroll SBBI Yearbook. 45 See Roger A.

BULKLEY, DI INTERMOUNTAIN GAS ke = rf + 0.75β(rm – rf) + 0.25(rm – rf) [5] 1 Where: 2 ke = the required market COE; 3 β = Adjusted Beta coefficient of an individual security; 4 rf = the risk-free rate of return; and 5 rm = the required return on the market as a whole. 6 In essence, the Empirical form of the CAPM addresses the tendency of the 7 “traditional” CAPM to underestimate the cost of equity for companies with low Beta 8 coefficients such as regulated utilities. In that regard, the ECAPM is not redundant to the 9 use of adjusted Betas; rather, it recognizes the results of academic research indicating that 10 the risk-return relationship is different (in essence, flatter) than estimated by the CAPM, 11 and that the CAPM underestimates the “alpha,” or the constant return term.46 12 As with the CAPM, my application of the ECAPM uses the forward-looking market 13 risk premium estimates, the three yields on 30-year Treasury securities noted earlier as the 14 risk-free rate, and the Bloomberg, Value Line, and long-term average Beta coefficients. 15 What are the results of your CAPM analyses? 16 A. As shown in Figure 9 (see also Exhibit No. 4), my traditional CAPM analysis produces a 17 range of returns from 10.34 percent to 11.30 percent. The ECAPM analysis results range 18 from 10.95 percent to 11.66 percent. 19 20 46 Id., at 191. PAGE 42 OF 79 A.

Bond Yield Plus Risk Premium Analysis 2 Please describe the Bond Yield Plus Risk Premium approach. 3 A. In general terms, this approach is based on the fundamental principle that equity investors 4 bear the residual risk associated with equity ownership and therefore require a premium 5 over the return they would have earned as a bondholder. That is, because returns to equity 6 holders have greater risk than returns to bondholders, equity investors must be 7 compensated to bear that risk. Risk premium approaches, therefore, estimate the COE as 8 the sum of the equity risk premium and the yield on a particular class of bonds. In my 9 analysis, I used actual authorized returns for natural gas distribution companies as the 10 historical measure of the COE to determine the risk premium. 11 Are there other considerations that should be addressed in conducting this analysis? 12 A. Yes, there are. It is important to recognize both academic literature and market evidence 13 indicating that the equity risk premium (as used in this approach) is inversely related to 14 the level of interest rates. That is, as interest rates increase, the equity risk premium 15 decreases, and vice versa. Consequently, it is important to develop an analysis that: (1) 16 reflects the inverse relationship between interest rates and the equity risk premium; and 17 PAGE 43 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS (2) relies on recent and expected market conditions. Such an analysis can be developed 1 based on a regression of the risk premium as a function of U.S. Treasury bond yields. If 2 we let authorized ROEs for natural gas utilities serve as the measure of required equity 3 returns and define the yield on the long-term U.S. Treasury bond as the relevant measure 4 of interest rates, the risk premium simply would be the difference between those two 5 points.47 6 Is the Bond Yield Plus Risk Premium analysis relevant to investors? 7 A. Yes, it is. Investors are aware of ROE awards in other jurisdictions, and they consider 8 those awards as a benchmark for a reasonable level of equity returns for utilities of 9 comparable risk operating in other jurisdictions. Because my Bond Yield Plus Risk 10 Premium analysis is based on authorized ROEs for utility companies relative to 11 corresponding Treasury yields, it provides relevant information to assess the return 12 expectations of investors in the current interest rate environment. 13 What did your Bond Yield Plus Risk Premium analysis reveal? 14 A. As shown in Figure 10 below, from 1992 through October 2022, there was a strong 15 negative relationship between risk premia and interest rates. To estimate that relationship, 16 I conducted a regression analysis using the following equation: 17 𝑅𝑃=𝑎+𝑏(𝑇) [6] 18 Where: 19 47 See S. Keith Berry, Interest Rate Risk and Utility Risk Premia during 1982-93, Managerial and Decision Economics, Vol. 19, No. 2 (March, 1998), in which the author used a methodology similar to the regression approach described below, including using allowed ROEs as the relevant data source, and came to similar conclusions regarding the inverse relationship between risk premia and interest rates. See also Robert S. Harris, Using Analysts’ Growth Forecasts to Estimate Shareholders Required Rates of Return at 66, Financial Management (Spring 1986). PAGE 44 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS RP = Risk Premium (difference between allowed ROEs and the yield on 30-year 1 U.S. Treasury bonds) 2 a = intercept term 3 b = slope term 4 T = 30-year U.S. Treasury bond yield 5 Data regarding allowed ROEs were derived from all of natural gas distribution rate 6 cases from 1992 through October 2022 as reported by Regulatory Research Associates 7 (“RRA”).48 This equation’s coefficients were statistically significant at the 99.00 percent 8 level. 9 Figure 10: Risk Premium Results 10 11 As shown in Exhibit No. 7, based on the current 30-day average of the 30-year U.S. 12 Treasury bond yield (i.e., 3.92 percent), the risk premium would be 6.25 percent, resulting 13 48 This analysis began with a total of 1,192 cases and was screened to eliminate limited issue rider cases, transmission-only cases, and cases that were silent with respect to the authorized ROE.

Based on the near-term (Q1 2023 – Q1 2024) 1 projections of the 30-year U.S. Treasury bond yield (i.e., 4.00 percent), the risk premium 2 would be 6.20 percent, resulting in an estimated ROE of 10.20 percent. Based on longer-3 term (2024 – 2028) projections of the 30-year U.S. Treasury bond yield (i.e., 3.80 percent), 4 the risk premium would be 6.32 percent, resulting in an estimated ROE of 10.12 percent. 5 How did the results of the Bond Yield Risk Premium inform your recommended ROE 6 for Intermountain? 7 A. I have considered the results of the Bond Yield Risk Premium analysis in setting my 8 recommended ROE for Intermountain’s natural gas distribution operations in Idaho. As 9 noted above, investors consider the ROE award of a company when assessing the risk of 10 that company as compared to utilities of comparable risk operating in other jurisdictions. 11 The Risk Premium analysis considers this comparison by estimating the return 12 expectations of investors based on the current and past ROE awards of natural gas 13 distribution companies across the U.S. 14 REGULATORY AND BUSINESS RISKS 15 Q. Do the DCF, CAPM, and ECAPM results for the proxy group, taken alone, provide 16 an appropriate estimate of the COE for the Company? 17 A. No. These results provide only a range of the appropriate estimate of Intermountain’s COE. 18 Several additional factors must also be considered with respect to their overall effect on 19 PAGE 46 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS the Company’s risk profile relative to the proxy group when determining where the COE 1 falls within the range of results. 2 A. Small Size 3 Please explain the risk associated with small size. 4 A. Both the financial and academic communities have long accepted the proposition that the 5 COE for small firms is subject to a “size effect”. While empirical evidence of the size 6 effect often is based on studies of industries other than regulated utilities, utility analysts 7 also have noted the risk associated with small market capitalizations. Specifically, an 8 analyst for Ibbotson Associates noted: 9 For small utilities, investors face additional obstacles, such as a smaller 10 customer base, limited financial resources, and a lack of diversification 11 across customers, energy sources, and geography. These obstacles imply a 12 higher investor return.49 13 How does the smaller size of a utility affect its business risk? 14 A. In general, smaller companies are less able to withstand adverse events that affect their 15 revenues and expenses. The impact of weather variability, the loss of large customers to 16 bypass opportunities, or the destruction of demand as a result of general macroeconomic 17 conditions or fuel price volatility will have a proportionately greater impact on the 18 earnings and cash flow volatility of smaller utilities. Similarly, capital expenditures for 19 non-revenue producing investments, such as system maintenance and replacements, will 20 put proportionately greater pressure on customer costs, potentially leading to customer 21 attrition or demand reduction. Taken together, these risks affect the return required by 22 investors for smaller companies. 23 49 Michael Annin, Equity and the Small-Stock Effect, Public Utilities Fortnightly, October 15, 1995. PAGE 47 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS How do Intermountain’s natural gas operations in Idaho compare in size to the proxy 1 group companies? 2 A. Intermountain’s natural gas operations in Idaho are substantially smaller than the median 3 for the proxy group companies in terms of market capitalization. Exhibit No. 8 provides 4 the actual market capitalization for the proxy group companies and estimates the implied 5 market capitalization for Intermountain’s natural gas operations in Idaho (i.e., the implied 6 market capitalization if Intermountain’s natural gas operations in Idaho were a stand-7 alone publicly traded entity). To estimate the size of the Company’s market capitalization 8 relative to the proxy group, I used the Company’s proposed capital structure equity 9 component of $193.76 million.50 I then applied the median market-to-book ratio for the 10 proxy group of 1.60 to the implied common equity balance of Intermountain’s natural gas 11 operations in Idaho and arrived at an implied market capitalization of approximately 12 $310.86 million, or 7.77 percent of the median market capitalization for the proxy group. 13 How did you estimate the size premium for Intermountain? 14 A. Given this relative size information, it is possible to estimate the impact of size on the 15 COE for Intermountain’s natural gas operations in Idaho using Kroll Cost of Capital 16 Navigator data that estimates the stock risk premia based on the size of a company’s 17 market capitalization.51 As shown in Exhibit No. 8, the median market capitalization of 18 the proxy group of approximately $4.00 billion corresponds to the fifth decile of Kroll’s 19 market capitalization data.52 Based on Kroll’s analysis, that decile corresponds to a size 20 premium of 0.89 percent (i.e., 89 basis points). The implied market capitalization of 21 50 Company provided data. 51 Kroll Cost of Capital Navigator – Size Premium. Annual Data as of December 31, 2021. 52 Ibid. PAGE 48 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Intermountain’s natural gas operations in Idaho of approximately $310.86 million falls 1 within the ninth decile, which comprises market capitalization levels up to $627.80 2 million and corresponds to a size premium of 2.10 percent (i.e., 210 basis points). The 3 difference between those size premia is 121 basis points (i.e., 2.10 percent minus 0.89 4 percent). 5 Were utility companies included in the size premium study conducted by Kroll? 6 A. Yes. In fact, as shown in Exhibit 7.2 of Kroll’s 2019 Valuation Handbook, OGE Energy 7 Corp. had the largest market capitalization of the companies contained in the fourth 8 decile.53 Therefore, Kroll did include utility companies in its size risk premium study. 9 Is the size premium applicable to companies in regulated industries such as natural 10 gas utilities? 11 A. Yes, it is. For example, Thomas Zepp in his article “Utility stocks and the size effect – 12 revisited” provided the results of two studies which showed evidence of the required risk 13 premium for small water utilities. The first study conducted by the California Public 14 Utilities Commission Staff (“CPUC Staff”) computed proxies for Beta risk using 15 accounting data from 1981 through 1991 for 58 water utilities and concluded that smaller 16 water utilities had greater risk and required higher returns on equity than larger water 17 utilities.54 The second study referenced by Zepp examined the differences in required 18 returns over the period of 1987-1997 for two large and two small water utilities in 19 California. As Zepp showed, the required return for the two small water utilities 20 53 Duff &Phelps, Valuation Handbook: Guide to Cost of Capital, 2019, Exhibit 7.2. 54 Zepp, Thomas M. “Utility Stocks and the Size Effect—Revisited.” The Quarterly Review of Economics and Finance, vol. 43, no. 3, 2003, pp. 578–582., doi:10.1016/s1062-9769(02)00172-2. PAGE 49 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS calculated using the DCF model was on average 99 basis points higher than the two 1 larger water utilities.55 2 Additionally, Stéphane Chrétien and Frank Coggins in the article “Cost of Equity 3 for Energy Utilities: Beyond the CAPM”,56 recently studied the CAPM and its ability to 4 estimate the risk premium for the utility industry in particular subgroups of utilities. One 5 of the subgroups was a group of natural gas distribution companies that contained many of 6 the same natural gas distribution companies included in my proxy group.57 The article 7 considered the CAPM, the Fama-French three-factor model and a model similar to the 8 ECAPM that I have also considered above. In the article, the Fama-French three-factor 9 model explicitly included an adjustment to the CAPM for risk associated with size. As 10 Chrétien and Coggins show the Beta coefficient on the size variable for the U.S. natural 11 gas utility group was positive and statistically significant indicating that small size risk was 12 relevant for regulated natural gas utilities.58 These two studies demonstrate that the size 13 premium is evident in market data and is clearly applicable to natural gas and water utilities. 14 55 Ibid. 56 Chrétien, Stéphane, and Frank Coggins. “Cost Of Equity For Energy Utilities: Beyond The CAPM.” Energy Studies Review, vol. 18, no. 2, 2011, doi:10.15173/esr.v18i2.531. 57 The U.S. natural gas utility group included: AGL Resources Inc., Atmos Energy Corp., Laclede Group, New Jersey Resources Corp., Northwest Natural Gas Co., Piedmont Natural Gas Co., South Jersey Industries, Southwest Gas Corp. and WGL Holdings Inc. 58 Chrétien, Stéphane, and Frank Coggins. “Cost of Equity For Energy Utilities: Beyond The CAPM.” Energy Studies Review, vol. 18, no. 2, 2011, doi:10.15173/esr.v18i2.531. PAGE 50 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Have regulators in other jurisdictions made a specific risk adjustment to the COE 1 results based on a company’s small size? 2 A. Yes. In Order No. 15, the Regulatory Commission of Alaska (“RCA”) concluded that 3 Alaska Electric Light and Power Company (“AEL&P”) was riskier than the proxy group 4 companies due to small size as well as other business risks. The RCA did “not believe 5 that adopting the upper end of the range of ROE analyses in this case, without an explicit 6 adjustment, would adequately compensate AEL&P for its greater risk.”59 Thus, the RCA 7 awarded AEL&P an ROE of 12.875 percent which was 108 basis points above the 8 highest COE estimate from any model presented in the case.60 Similarly, in Order No. 19, 9 the RCA noted that small size as well as other business risks such as structural regulatory 10 lag, weather risk, alternative rate mechanisms, gas supply risk, geographic isolation and 11 economic conditions increased the risk of ENSTAR Natural Gas Company.61 Ultimately, 12 the RCA concluded that: 13 Although we agree that the risk factors identified by ENSTAR increase its 14 risk, we do not attempt to quantify the amount of that increase. Rather, we 15 take the factors into consideration when evaluating the remainder of the 16 record and the recommendations presented by the parties. After applying 17 our reasoned judgment to the record, we find that 11.875% represents a fair 18 ROE for ENSTAR.62 19 Additionally, in Docket No. E017/GR-15-1033 for Otter Tail Power Company 20 (“Otter Tail”), the Minnesota Public Utilities Commission (“Minnesota PUC”) selected an 21 59 Docket No. U-10-29, In the Matter of the Revenue Requirement and Cost of Service Study Designated as TA381- 1 Filed by Alaska Electric Light and Power Company, Order entered September 2, 2011 (Order No. 15) at 37. 60 Id., at 32 and 37. 61 Docket No. U-16-066, In the Matter of the Tariff Revision Designated as TA285-4 Filed by ENSTAR Natural Gas Company, A Division of Semco Energy, Inc., Order entered September 22, 2017 (Order No. 19) at 50-52. 62 Ibid.

The Minnesota PUC stated: 2 The record in this case establishes a compelling basis for selecting an ROE 3 above the mean average within the DCF range, given Otter Tail’s unique 4 characteristics and circumstances relative to other utilities in the proxy 5 group. These factors include the company’s relatively smaller size, 6 geographically diffuse customer base, and the scope of the Company’s 7 planned infrastructure investments.63 8 Finally, in Opinion No. 569 and 569-A, the FERC has relied on a size premium 9 adjustment in its CAPM estimates for electric utilities. In those decisions, the FERC noted 10 that “the size adjustment was necessary to correct for the CAPM’s inability to fully account 11 for the impact of firm size when determining the cost of equity.”64,65 12 How have you considered the smaller size of Intermountain’s natural gas distribution 13 operations in Idaho in your recommended ROE? 14 A. While I have estimated the effect of the size of Intermountain’s natural gas distribution 15 operations on the COE, I am not proposing a specific adjustment for this risk factor. 16 Rather, I believe it is important to consider the small size of Intermountain’s natural gas 17 distribution operations in the determination of where, within the range of analytical 18 results, the Company’s required COE falls. Therefore, the additional risk associated with 19 small size indicates that the Company’s ROE should be established above the mean and 20 median results for the proxy group companies. 21 63 Order in Docket No. E017/GR-15-1033, In the Matter of the Application of Otter Tail Power Company for Authority to Increase Rates for Electric Service in the State of Minnesota (August 16, 2016) at 55. 64 Federal Energy Regulatory Commission, Opinion No. 569-A, May 21, 2020, at para 75. 65 The U.S. Court of Appeals recently vacated the FERC Order 569 decisions that related to its risk premium model and remanded the case to FERC to reopen proceedings.

The Company’s current projections for 2023 through 2027 include at least $322.64 4 million in capital investments for the period.66 Based on the Company’s net utility plant 5 of approximately $458.07 million as of December 31, 2021,67 the projected capital 6 expenditures are approximately 70.43 percent of Intermountain’s net utility plant as of 7 December 31, 2021. 8 How is the Company’s risk profile affected by their substantial capital expenditure 9 requirements? 10 A. As with any utility faced with substantial capital expenditure requirements, the 11 Company’s risk profile may be adversely affected in two significant and related ways: (1) 12 the heightened level of investment increases the risk of under-recovery or delayed 13 recovery of the invested capital, particularly since the Company does not have any 14 mechanism to provide for recovery between rate cases; and (2) an inadequate return 15 would put downward pressure on key credit metrics. 16 Do credit rating agencies recognize the risks associated with elevated levels of capital 17 expenditures? 18 A. Yes, they do. From a credit perspective, the additional pressure on cash flows associated 19 with high levels of capital expenditures exerts corresponding pressure on credit metrics 20 66 Company provided data. 67 Company provided data. PAGE 53 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS and, therefore, credit ratings. To that point, S&P explains the importance of regulatory 1 support for large capital projects: 2 When applicable, a jurisdiction’s willingness to support large capital 3 projects with cash during construction is an important aspect of our analysis. 4 This is especially true when the project represents a major addition to rate 5 base and entails long lead times and technological risks that make it 6 susceptible to construction delays. Broad support for all capital spending is 7 the most credit-sustaining. Support for only specific types of capital 8 spending, such as specific environmental projects or system integrity plans, 9 is less so, but still favorable for creditors. Allowance of a cash return on 10 construction work-in-progress or similar ratemaking methods historically 11 were extraordinary measures for use in unusual circumstances, but when 12 construction costs are rising, cash flow support could be crucial to maintain 13 credit quality through the spending program. Even more favorable are those 14 jurisdictions that present an opportunity for a higher return on capital 15 projects as an incentive to investors.68 16 Therefore, to the extent that Intermountain’s rates do not permit the opportunity to 17 earn an appropriate return and recover its capital investments on a regular and timely basis, 18 the Company will face increased recovery risk and thus increased pressure on its credit 19 metrics. 20 How do Intermountain’s capital expenditure requirements for the Idaho natural gas 21 operations compare to those of the proxy group companies? 22 A. As shown in Exhibit No. 9, I calculated the ratio of expected capital expenditures to net 23 utility plant for Intermountain’s natural gas distribution operations in Idaho and each of 24 the companies in the proxy group by dividing each company’s projected capital 25 expenditures for the period from 2023-2027 by its total net utility plant as of December 26 31, 2021. As shown in Exhibit No. 9 (see also Figure 11 below), the Company’s ratio of 27 capital expenditures as a percentage of net utility plant is 70.43 percent, which is above 28 68 S&P Global Ratings, “Assessing U.S. Investor-Owned Utility Regulatory Environments,” August 10, 2016, at 7. PAGE 54 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS the median for the proxy group companies of 68.83 percent. This result indicates a risk 1 level for Intermountain’s natural gas distribution operations in Idaho that is higher than 2 the proxy group companies. 3 4 PAGE 55 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Figure 11: Comparison of Capital Expenditures 1 2 Does the Company have a capital tracking mechanism to recover the costs associated 3 with its capital expenditures plan between rate cases? 4 A. No. Intermountain does not have a mechanism to recover capital investment costs 5 between rate cases . Therefore, Intermountain depends entirely on rate case filings for 6 capital cost recovery. 7 Are capital investment recovery mechanisms common amongst natural gas 8 distribution utilities? 9 A. Yes. As shown in Exhibit No. 10, 18 out of 25 (or approximately 72 percent) of the 10 operating companies of the proxy group recover costs through capital investment 11 reconciling mechanisms. Therefore, the Company has significantly greater risk relative to 12 the proxy group from the regulatory lag associated with the recovery of its capital 13 expenditures plan. 14 51.09%52.89% 63.21%70.43%74.45% 88.74%89.67% 1 2 3 4 5 6 7 8 9 10 0.00% 10.00% 20.00% 30.00% 40.00% 50.00% 60.00% 70.00% 80.00% 90.00% 100.00% NWN OGS SR IMG NI NJR ATO Median= 68.83% PAGE 56 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS What are your conclusions regarding the effect of the Company’s capital spending 1 requirements on its risk profile and COE? 2 A. The Company’s capital expenditure requirements as a percentage of net utility plant are 3 significant and will continue over the next few years. Additionally, unlike a number of 4 the operating subsidiaries of the proxy group, Intermountain does not have a 5 comprehensive capital tracking mechanism to recover the Company’s projected capital 6 expenditures. Therefore, Intermountain’s significant capital expenditures plan and limited 7 ability to recover the capital investment on an as incurred basis results in a risk profile 8 that is greater than that of the proxy group and supports an ROE toward the higher end of 9 the reasonable range of ROEs. 10 C. Regulatory Risk 11 How does the regulatory environment affect investors’ risk assessments? 12 A. The ratemaking process is premised on the principle that, for investors and companies to 13 commit the capital needed to provide safe and reliable utility service, the subject utility 14 must have the opportunity to recover the return of, and the market-required return on, 15 invested capital. Regulatory authorities recognize that because utility operations are 16 capital intensive, regulatory decisions should enable the utility to attract capital at 17 reasonable terms; doing so balances the long-term interests of investors and customers. 18 To achieve this balance, the Company must be able to finance its operations assuming a 19 reasonable opportunity to earn an appropriate return on invested capital to maintain an 20 acceptable financial profile. In that respect, the regulatory environment is one of the most 21 important factors considered in both debt and equity investors’ risk assessments. 22 From the perspective of debt investors, the authorized return should enable the 23 Company to generate the cash flow needed to meet its near-term financial obligations, 24 PAGE 57 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS make the capital investments needed to maintain and expand its systems, and maintain the 1 necessary levels of liquidity to fund unexpected events. This financial liquidity must be 2 derived not only from internally generated funds, but also by efficient access to capital 3 markets. Moreover, because fixed income investors have many investment alternatives, 4 even within a given market sector, the Company’s financial profile must be adequate on a 5 relative basis to ensure its ability to attract capital under a variety of economic and financial 6 market conditions. 7 Equity investors, on the other hand, require that the authorized return be adequate 8 to provide a risk-comparable return on the equity portion of the Company’s capital 9 investments. Because equity investors are the residual claimants on the Company’s cash 10 flows (which is to say that the equity return is subordinate to interest payments), they are 11 particularly concerned with the strength of regulatory support and its effect on future cash 12 flows. 13 How do credit rating agencies consider regulatory risk in establishing a company’s 14 credit rating? 15 A. Both S&P and Moody’s consider the overall regulatory framework in establishing credit 16 ratings. Moody’s establishes credit ratings based on four key factors: (1) regulatory 17 framework; (2) the ability to recover costs and earn returns; (3) diversification; and (4) 18 financial strength, liquidity, and key financial metrics. Of these criteria, regulatory 19 framework, and the ability to recover costs and earn returns are each given a broad rating 20 PAGE 58 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS factor of 25.00 percent. Therefore, Moody’s assigns regulatory risk a 50.00 percent 1 weighting in the overall assessment of business and financial risk for regulated utilities.69 2 S&P also identifies the regulatory framework as an important factor in credit ratings 3 for regulated utilities, stating: “One significant aspect of regulatory risk that influences 4 credit quality is the regulatory environment in the jurisdictions in which a utility 5 operates.”70 S&P identifies four specific factors that it uses to assess the credit implications 6 of the regulatory jurisdictions of investor-owned regulated utilities: (1) regulatory stability; 7 (2) tariff-setting procedures and design; (3) financial stability; and (4) regulatory 8 independence and insulation.71 9 How does the regulatory environment in which a utility operates affect its access to 10 and cost of capital? 11 A. The regulatory environment can significantly affect both the access to, and cost of capital 12 in several ways. First, the proportion and cost of debt capital available to utility 13 companies are influenced by the rating agencies’ assessment of the regulatory 14 environment. As noted by Moody’s, “[f]or rate regulated utilities, which typically operate 15 as a monopoly, the regulatory environment and how the utility adapts to that environment 16 are the most important credit considerations.”72 Moody’s further highlighted the 17 relevance of a stable and predictable regulatory environment to a utility’s credit quality, 18 69 Moody’s Investors Service, Rating Methodology: Regulated Electric and Gas Utilities, June 23, 2017, at 4. 70 Standard & Poor’s Global Ratings, Ratings Direct, U.S. and Canadian Regulatory Jurisdictions Support Utilities’ Credit Quality—But Some More So Than Others, June 25, 2018, at 2. 71 Id., at 1. 72 Moody’s Investors Service, Rating Methodology: Regulated Electric and Gas Utilities, June 23, 2017, at 6. PAGE 59 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS noting: “[b]roadly speaking, the Regulatory Framework is the foundation for how all the 1 decisions that affect utilities are made (including the setting of rates), as well as the 2 predictability and consistency of decision-making provided by that foundation.”73 3 Have you conducted any analysis of the regulatory framework in Idaho relative to the 4 jurisdictions in which the companies in your proxy group operate? 5 A. Yes. I have evaluated the regulatory framework in Idaho considering two factors which 6 are important to ensuring Intermountain maintains access to capital at reasonable terms. 7 As I will discuss in more detail below, the two factors are: (1) cost recovery mechanisms 8 which allow a utility to recover costs in a timely manner between rate cases and provide 9 the utility the opportunity to earn its authorized return; and (2) comparable return 10 standard74 because an awarded ROE that is significantly below the ROEs awarded to 11 other utilities with comparable risks can affect the ability of a utility to attract capital at 12 reasonable terms. 13 1. Cost Recovery Mechanisms 14 Have you conducted any analysis to compare the cost recovery mechanisms of 15 Intermountain to the cost recovery mechanisms approved in the jurisdictions in 16 which the companies in your proxy group operate? 17 A. Yes. I selected three mechanisms that are important to provide a regulated utility an 18 opportunity to earn its authorized ROE. These are: (1) test year convention (i.e., forecast 19 vs. historical test year); (2) use of revenue decoupling mechanisms or other clauses that 20 mitigate volumetric risk; and (3) prevalence of capital cost recovery between rate cases. 21 73 Id. 74 Hope and Bluefield require the return be commensurate with returns on investments in enterprises with similar risk. PAGE 60 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS The results of my regulatory risk assessment are summarized as follows, and the details 1 are shown in Exhibit No. 10: 2 Test Year Convention: Intermountain is relying on a partially forecast test year for 3 the period ending December 31, 2022. Similarly, 48 percent of the operating 4 companies held by the proxy group provide service in jurisdictions that use a fully 5 or partially forecast test year. Forecast test years have been relied on for several 6 years and produce cost estimates that are more reflective of future costs which 7 results in more accurate recovery of incurred costs and mitigates the regulatory lag 8 associated with historical test years. As Lowry, Hovde, Getachew, and Makos 9 explain in their 2010 report, Forward Test Years for US Electric Utilities: 10 This report provides an in depth discussion of the test year issue. It includes 11 the results of empirical research which explores why the unit costs of 12 electric IOUs are rising and shows that utilities operating under forward test 13 years realize higher returns on capital and have credit ratings that are 14 materially better than those of utilities operating under historical test 1 15 years. The research suggests that shifting to a future test year is a prime 16 strategy for rebuilding utility credit ratings as insurance against an uncertain 17 future.75 18 Volumetric Risk: Intermountain does not have protection against volumetric risk in 19 Idaho, either through a revenue decoupling mechanism or a weather normalization 20 adjustment clause. By comparison, 88 percent of the operating companies in the 21 proxy group have some form of protection against volumetric risk. 22 Capital Cost Recovery: Intermountain does not have a capital tracking mechanism 23 to recover capital investment costs between rate cases. However, as discussed 24 75 M.N. Lowry, D. Hovde, L. Getachew, and M. Makos, Forward Test Years for US Electric Utilities prepared for Edison Electric Institute, August 2010, at 1. PAGE 61 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS above, approximately 72 percent of the operating companies in the proxy group 1 have some form of capital cost recovery mechanism in place. 2 2. Authorized ROEs 3 How do recent returns in Idaho compare to the authorized returns in other 4 jurisdictions? 5 A. Figure 12 below shows the authorized returns for natural gas distribution companies in 6 other jurisdictions since January 2009, and the returns authorized in Idaho for natural gas 7 companies. While partially the result of settlement agreements approved by the 8 Commission, as shown in Figure 12, the authorized returns for natural gas distribution 9 companies in Idaho have been below the average authorized ROE for natural gas 10 distribution companies in other jurisdictions over the past five years. 11 Figure 12: Comparison of Idaho and U.S. Authorized Electric Returns76 12 13 76 S&P Capital IQ Pro. Authorized ROEs in Arizona and New York are excluded because they are not considered comparable to the manner in which ROE is established in Idaho by the Commission. Specifically, authorizations in Arizona were excluded because their return is subject to a fair value rate base calculation, which is not the case in Idaho. Authorized ROEs in New York have been excluded since the results are relatively formulaic with each utility generally receiving the same ROE without differentiation of risk. 8.50% 9.00% 9.50% 10.00% 10.50% 11.00% 11.50% 1/1/2009 9/28/2011 6/24/2014 3/20/2017 12/15/2019 9/10/2022 Au t h o r i z e d R O E U.S. Average Excl. ID U.S. Auhorized ROEs Idaho Authorized ROEs Rate CaseData through October 31, 2022 PAGE 62 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Should the Commission be concerned about authorizing equity returns that are at the 1 low end of the range established by other state regulatory jurisdictions? 2 A. Yes. Placing Intermountain at the low end of authorized ROEs across the country can 3 negatively affect the Company’s access to capital and the overall cost of capital over the 4 longer term. As I discuss below, the recent negative rate case determination, including a 5 below average authorized ROE, for Arizona Public Service Company (“APS”) resulted in 6 a 24 percent decline in the share price for Pinnacle West Capital Corporation (“PNW”), 7 increasing the overall COE for that company. 8 Second, as noted in Sections IV and VI, interest rates have been increasing in 2022 9 and are expected to continue to increase as the Federal Reserve continues to normalize 10 monetary policy. Therefore, historical authorized ROEs provide investors with a range of 11 recent returns, these decisions do not take into consideration the effect of current market 12 conditions on the investor, required return. Therefore, it is important that the Commission 13 consider the results of forward looking methodologies such as the CAPM, ECAPM, and 14 Bond Yield Plus Risk Premium which rely directly on current and projected interest rates 15 in the estimation of the COE. 16 Do credit rating agencies consider the authorized ROE in the overall risk assessment 17 of a utility? 18 A. Yes, they do. To the extent that the returns in a jurisdiction are lower than the returns 19 that have been authorized more broadly, credit rating agencies will consider this in the 20 overall risk assessment of the regulatory jurisdiction in which the company operates. It is 21 important to consider credit ratings because they affect the overall cost of borrowing, and 22 they act as a signal to equity investors about the risk of investing in the equity of a 23 PAGE 63 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS company. Therefore, lower credit ratings can affect both the cost of debt and equity. 1 Examples of recent credit rating agency responses include ALLETE, Inc., and PNW. 2 Moody’s downgraded ALLETE, Inc. from A3 to Baa1 primarily based on the less than 3 favorable outcome in Minnesota Power’s last fully litigated rate case in Minnesota which 4 included what Moody’s noted was a below average authorized ROE of 9.25 percent.77 In 5 addition, FitchRatings recently downgraded and maintained a negative outlook for APS 6 and its parent, PNW, following the hearings conducted by the Arizona Corporation 7 Commission (“ACC”) in October 2021 regarding APS’ current rate case proceeding.78 8 While the ACC had not issued a final order in APS’ rate case at the time, FitchRatings 9 noted that the developments at the hearing in October indicate a likely credit negative 10 outcome that will negatively affect the financial metrics of both APS and PNW. It is also 11 important to note that both Standard & Poor’s and Moody’s downgraded PNW’s and 12 APS’ credit rating and put the companies on credit watch negative following the 13 Commission’s November vote that officially authorized the 8.70 percent ROE.79 14 Are you aware of any utilities whose market data has been affected by adverse rate 15 case developments? 16 A. Yes, I am. The market has responded negatively to recent returns authorized by the 17 ACC. As noted above, the most recent ROE determination in Arizona was for APS. The 18 77 Moody’s Investors Service, “Credit Opinion: ALLETE, Inc. Update following downgrade,” at 3 (April 3, 2019). 78 FitchRatings, “Fitch Downgrades Pinnacle West Capital & Arizona Public Service to 'BBB+'; Outlooks Remain Negative,” October 12, 2021. 79 See S&P Capital IQ and Moody’s Investors Service, “Rating Actions: Moody's downgrades Pinnacle West to Baa1 and Arizona Public Service to A3; outlook negative,” (Nov. 17, 2021). PAGE 64 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Recommended Opinion and Order (“ROO”) issued in the APS rate proceeding on August 1 2, 2021, recommended an ROE of 9.16 percent. In October 2021, that recommendation 2 was amended to reduce the company’s ROE to 8.70 percent. The final ROE that was 3 established for APS was 8.70 percent.80 The market reacted strongly to the proposed 4 order and subsequent amendment and final decision. Guggenheim Securities LLC, an 5 equity analyst that follows PNW, the parent company of APS, informed its clients that: 6 [T]he “Arizona Corporation Commission is now confirmed to be the single 7 most value destructive regulatory environment in the country as far as 8 investor-owned utilities are concerned”.81 9 S&P Global Market Intelligence (“Regulatory Research Associates”) noted that 10 this decision was “among the lowest ROEs RRA had encountered in its coverage of 11 vertically integrated electric utilities in the past 30 years.”82 12 As shown in Figure 13 below, PNW’s stock price declined approximately 24 13 percent from August 2, 2021 to November 4, 2021 following the issuance of the ROO, 14 which recommended an ROE of 9.16 percent, and then the subsequent amendment to that 15 opinion recommending the 8.70 percent ROE ultimately adopted by the ACC. Moreover, 16 the Value Line five-year projected EPS growth rates for this company have fallen from 5.0 17 percent in July 2021, prior to the deliberations in the rate proceeding to “Nil” in October 18 2021 and most recently 0.5 percent in October 2022. For PNW, the APS decision has had 19 a significant effect on the share price and growth rate assumptions used in the DCF model. 20 80 Arizona Corporation Commission Docket No. E-01345A-19-0236, Commissioner Olson Proposed Amendment No. 1 to the Recommended Opinion and Order.

PAGE 65 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Figure 13: Pinnacle West Capital Stock Price VS. S&P 500 1 2 How should the Commission use the information regarding authorized ROEs in other 3 jurisdictions in determining the ROE for Intermountain? 4 A. As discussed above, the companies in the proxy group operate in multiple jurisdictions 5 across the U.S. Since Intermountain must compete directly for capital with investments 6 of similar risk, it is appropriate to review the authorized ROEs in other jurisdictions. The 7 comparison is important because investors are considering the authorized returns across 8 the U.S. and are likely to invest equity in those utilities with the highest returns. 9 What is your conclusion regarding the regulatory framework in Idaho as compared 10 with the jurisdictions in which the proxy group companies operate? 11 A. As discussed throughout this section of my testimony, both Moody’s and S&P have 12 identified the supportiveness of the regulatory environment as an important consideration 13 in developing their overall credit ratings for regulated utilities. Considering the 14 regulatory adjustment mechanisms, many of the companies in the proxy group have 15 3,000.00 3,200.00 3,400.00 3,600.00 3,800.00 4,000.00 4,200.00 4,400.00 4,600.00 4,800.00 50.00 55.00 60.00 65.00 70.00 75.00 80.00 85.00 90.00 1/4/2021 2/4/2021 3/4/2021 4/4/2021 5/4/2021 6/4/2021 7/4/2021 8/4/2021 9/4/2021 10/4/2021 11/4/2021 S& P 5 0 0 PN W S t o c k P r i c e PNW S&P 500 ROO Amendment ROO issued ROO Issued (ROE -9.16%)ROO Ammendment (ROE -8.70%) PAGE 66 OF 79 A.

Additionally, authorized 2 ROEs in Idaho have been below the average authorized ROEs for natural gas distribution 3 utilities across the U.S. For these reasons, I conclude that Intermountain has greater than 4 average regulatory risk when compared to the proxy group, indicating that the authorized 5 ROE for Intermountain should be higher than the proxy group mean/median. 6 D. Service Territory Risk 7 Please summarize Intermountain’s service territory risk. 8 A. As noted above, Intermountain serves approximately 404,770 retail and 109 9 transportation customers in Idaho. The Company’s service area is in Southern Idaho, 10 where most of Intermountain’s industrial customers are in the agricultural and food 11 processing industry which represents a large portion of the economy and supports the 12 Company’s commercial and residential customers. Approximately 43.22 percent of 13 Intermountain’s total company utility gas sales in 2021 were derived from industrial 14 customers. As shown in Figure 14, Intermountain’s commercial and industrial sales 15 volume as a percentage of total utility gas sales was 66.16 percent, which was higher than 16 all but two of the proxy group companies. However, the two proxy group companies (i.e., 17 One Gas and NiSource) with a higher percentage of commercial and industrial sales 18 volume were only slightly higher with One Gas and NiSource deriving 66.27 percent and 19 66.63 percent, respectively, of their natural gas volumes from commercial and industrial 20 customers. 21 22 PAGE 67 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Figure 14: Customer Concentration83 1 2 How does customer concentration and the Company’s service territory risk affect 3 business risk? 4 A. A relatively high concentration of commercial and industrial customers results in higher 5 business risk. Commercial and industrial customers are large, and can represent a 6 significant portion of a company’s sales which could be lost if a customer goes out of 7 business or switches suppliers. As noted by Dhaliwal, Judd, Serfling and Shaikh in their 8 article, Customer Concentration Risk and the Cost of Equity Capital: 9 83 EIA FORM 176 - Other sales includes Electric Power and Vehicle Fuel Volume. 0.00% 10.00% 20.00% 30.00% 40.00% 50.00% 60.00% 70.00% 80.00% 90.00% 100.00% NJR SR NWN ATO IMG OGS NI Industrial %Commercial %Other %Residential % PAGE 68 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Depending on a major customer for a large portion of sales can be risky for 1 a supplier for two primary reasons. First, a supplier faces the risk of losing 2 substantial future sales if a major customer becomes financially distressed 3 or declares bankruptcy, switches to a different supplier, or decides to 4 develop products internally. Consistent with this notion, Hertzel et al. 5 (2008) and Kolay et al. (2015) document negative supplier abnormal stock 6 returns to the announcement that a major customer declares bankruptcy. 7 Further, a customer’s weak financial condition or actions could signal 8 inherent problems about the supplier’s viability to its remaining customers 9 and lead to compounding losses in sales. Second, a supplier faces the risk 10 of losing anticipated cash flows from being unable to collect outstanding 11 receivables if the customer goes bankrupt. This assertion is consistent with 12 the finding that suppliers offering customers more trade credit experience 13 larger negative abnormal stock returns around the announcement of a 14 customer filing for Chapter 11 bankruptcy (Jorion and Zhang, 2009; Kolay 15 et al., 2015).84 16 17 Therefore, a company that has a high degree of customer concentration will be 18 inherently riskier than a company that derived income from a larger customer base. 19 Furthermore, as Dhaliwal, Judd, Serfling and Shaik detail in the article, the increased risk 20 associated with a more concentrated customer base will have the effect of increasing a 21 company’s COE.85 22 Please describe how changes in economic conditions and the interdependent nature 23 of Intermountain’s service territory can affect its business risk? 24 A. While Intermountain doesn’t depend on any one major customer, Intermountain has a 25 high concentration of industrial customers. Intermountain’s major industrial customers 26 are engaged in the agricultural industry primarily in food processing including but not 27 limited to potato, dairy and meat processing. Commodity and energy price volatility, 28 changes in consumer preferences, increased domestic and international competition as 29 84 Dhaliwal, Dan S., J. Scott Judd, Matthew A. Serfling, and Sarah Shaikh. “Customer Concentration Risk and the Cost of Equity Capital.” SSRN Electronic Journal (2016): 1-2. Web. 85 Id, at 4. PAGE 69 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS well as the current labor shortages and the economic effect of the COVID-19 pandemic 1 are some of the risk factors currently faced by the food processing industry. Depending 2 on how significant the financial effect of the referenced events, companies could respond 3 to such events by decreasing production which will result in volatility in natural gas sales 4 for Intermountain since the Company’s load is heavily based on the food processing 5 industry. 6 What portion of Intermountain’s natural gas deliveries concentrated in one industry? 7 A. In 2021, 37.02 percent of Intermountain’s total natural gas sales were derived from 8 industrial customers in the food processing industry.86 Moreover, since the economy in 9 Southern Idaho is reliant on the food processing industry, Intermountain’s commercial 10 and residential customers also rely on the industry for sales and employment. For 11 example, the agricultural and food processing industry employs nearly 5.4 percent of 12 Idaho’s workforce and contributed $3.9 billion to Idaho’s GDP which represents over 9 13 percent of Idaho’s total GDP.87 Furthermore, Southern Idaho is ranked number 3 in the 14 U.S. for food processing and is one of four regions in the U.S. to receive the U.S. 15 Department of Commerce’s Federal Manufacturing Community Designation in the 16 category of “All Things Food”. 88 Therefore, downside risks to the food processing such 17 as increases in commodity prices, labor shortages, changing consumer preferences and 18 increase domestic and international competition could have an effect on the economic 19 conditions in Intermountain’s service territory. This could result in a reduction in sales to 20 86 Company provided data. 87 Idaho Department of Commerce. “Food Production Industry Fact Sheet”. https://commerce.idaho.gov/content/uploads/2021/05/Industry-One-Sheet-Food-Production-1.pdf 88 Southern Idaho Economic Development, “Key Industries”. https://www.southernidaho.org/key-industries.html PAGE 70 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS industrial customers. If food processors reduce output, the effect would be compounded 1 by a decline in local employment which would also reduce natural gas deliveries for 2 Intermountain’s residential and commercial customers. 3 Are you aware of other risk factors that could affect Intermountain’s business 4 operations? 5 A. Yes. Intermountain is also in direct competition with other sources of energy such as 6 electricity, diesel, solar, and wind among others. This creates an additional risk that 7 customers in the commercial and industrial classes could convert to a different source of 8 energy. Thus, Intermountain’s reliance on a large percentage of commercial and 9 industrial load results in an increased risk of volatility with respect to sales, earnings, and 10 cash flow. 11 What is your conclusion regarding the Company’s customer concentration and its 12 effect on the cost of equity for Intermountain? 13 A. Intermountain is heavily reliant on sales to industrial customers. As noted above, 14 approximately 43.22 percent of Intermountain’s total natural gas deliveries in Idaho were 15 to industrial customers. This concentration is higher than all but two of the proxy group 16 companies. A high degree of customer concentration increases Intermountain’s risk 17 related to customer migration, changes in economic conditions and competition. This risk 18 is greater in Intermountain’s service territory because the residential and commercial 19 customers rely on the success of the food processing industry for sales and employment. 20 Increased customer and economic diversity decreases the effect that any one customer or 21 industry can have on a company’s sales. Thus, Intermountain’s service territory, where 22 industrial customers represent a large portion of natural gas sales and commercial and 23 PAGE 71 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS residential customers rely economically on the success of the one industry segment, 1 implies that Intermountain has an above average risk profile when compared to the 2 companies in the proxy group. 3 E. Flotation Cost 4 Q. What are flotation costs? 5 A. Flotation costs are the costs associated with the sale of new issues of common stock. 6 These costs include out-of-pocket expenditures for preparation, filing, underwriting, and 7 other issuance costs. 8 Q. Why is it important to consider flotation costs in the allowed ROE? 9 A. A regulated utility must have the opportunity to earn an ROE that is both competitive and 10 compensatory to attract and retain new investors. To the extent that a company is denied 11 the opportunity to recover prudently incurred flotation costs, actual returns will fall short 12 of expected (or required) returns, thereby diluting equity share value. 13 Q. Are flotation costs part of the utility’s invested costs or part of the utility’s expenses? 14 A. Flotation costs are part of the invested costs of the utility, which are properly reflected on 15 the balance sheet under “paid in capital.” They are not current expenses, and, therefore, 16 are not reflected on the income statement. Rather, like investments in rate base or the 17 issuance costs of long-term debt, flotation costs are incurred over time. As a result, the 18 great majority of a utility’s flotation cost is incurred prior to the test year but remains part 19 of the cost structure that exists during the test year and beyond, and as such, should be 20 recognized for ratemaking purposes. Therefore, it is irrelevant whether an issuance 21 occurs during the test year or is planned for the test year because failure to allow recovery 22 of past flotation costs may deny Intermountain the opportunity to earn its required ROR 23 in the future. 24 PAGE 72 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Q. Please provide an example of why a flotation cost adjustment is necessary to 1 compensate investors for the capital they have invested. 2 A. Suppose MDU Resources issues stock with a value of $100, and an equity investor 3 invests $100 in MDU Resources in exchange for that stock. Further suppose that, after 4 paying the flotation costs associated with the equity issuance, which include fees paid to 5 underwriters and attorneys, among others, MDU Resources ends up with only $97 of 6 issuance proceeds, rather than the $100 the investor contributed. MDU Resources invests 7 that $97 in plant used to serve its customers, which becomes part of rate base. Absent a 8 flotation cost adjustment, the investor will thereafter earn a return on only the $97 9 invested in rate base, even though she contributed $100. Making a small flotation cost 10 adjustment gives the investor a reasonable opportunity to earn the authorized return, 11 rather than the lower return that results when the authorized return is applied to an 12 amount less than what the investor contributed. 13 Q. Is the date of MDU Resources’ last issued common equity important in the 14 determination of flotation costs? 15 A. No. As shown in Exhibit No. 11, MDU Resources closed on equity issuances of 16 approximately $58 million and $54 million (for a total of 4.7 million shares of common 17 stock) in November 2002 and February 2004, respectively. The vintage of the issuance, 18 however, is not particularly important because the investor suffers a shortfall in every 19 year that he should have a reasonable opportunity to earn a return on the full amount of 20 capital that he has contributed. Returning to my earlier example, the investor who 21 contributed $100 is entitled to a reasonable opportunity to earn a return on $100 not only 22 in the first year after the investment, but in every subsequent year in which he has the 23 PAGE 73 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS $100 invested. Leaving aside depreciation, which is dealt with separately, there is no 1 basis to conclude that the investor is entitled to earn a return on $100 in the first year after 2 issuance, but thereafter is entitled to earn a return on only $97. As long as the $100 is 3 invested, the investor should have a reasonable opportunity to earn a return on the entire 4 amount. 5 Q. Is the need to consider flotation costs recognized by the academic and financial 6 communities? 7 A. Yes. The need to reimburse shareholders for the lost returns associated with equity 8 issuance costs is recognized by the academic and financial communities in the same spirit 9 that investors are reimbursed for the costs of issuing debt. This treatment is consistent 10 with the philosophy of a fair ROR. According to Dr. Shannon Pratt: 11 Flotation costs occur when new issues of stock or debt are sold to the public. 12 The firm usually incurs several kinds of flotation or transaction costs, which 13 reduce the actual proceeds received by the firm. Some of these are direct 14 out-of-pocket outlays, such as fees paid to underwriters, legal expenses, and 15 prospectus preparation costs. Because of this reduction in proceeds, the 16 firm’s required returns on these proceeds equate to a higher return to 17 compensate for the additional costs. Flotation costs can be accounted for 18 either by amortizing the cost, thus reducing the cash flow to discount, or by 19 incorporating the cost into the cost of capital. Because flotation costs are 20 not typically applied to operating cash flow, one must incorporate them into 21 the cost of capital.89 22 Q. How did you calculate the flotation costs for MDU Resources? 23 A. My flotation cost calculation is based on the costs of issuing equity that were incurred by 24 MDU Resources in its two most recent common equity issuance. These issuance costs 25 were applied to my proxy group. Applying the actual issuance costs for MDU Resources 26 89 Shannon P. Pratt, Cost of Capital Estimation and Applications, Second Edition, at 220-221. PAGE 74 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS provided in Exhibit No. 11, to the DCF analysis, the flotation costs are estimated to be 1 0.14 percent (i.e., 14 basis points). 2 Q. Do your final results include an adjustment for flotation cost recovery? 3 A. No. I did not make an explicit adjustment for flotation costs to any of my quantitative 4 analyses. Rather, I provide the above result for consideration in my recommended ROE, 5 which reflects the range of results from my Constant Growth DCF, CAPM, ECAPM and 6 Risk Premium analyses. 7 CAPITAL STRUCTURE 8 Is the capital structure of a company an important consideration in the determination 9 of the appropriate ROE? 10 A. Yes, it is. Assuming other factors equal, a higher debt ratio increases the risk to investors. 11 For debt holders, higher debt ratios result in a greater portion of the available cash flow 12 being required to meet debt service, thereby increasing the risk associated with the 13 payments on debt. The result of increased risk is a higher interest rate. The incremental 14 risk of a higher debt ratio is more significant for common equity shareholders. Common 15 shareholders are the residual claimants on the cash flow of a company. Therefore, the 16 greater the debt service requirement, the less cash flow available for common equity 17 holders. 18 What is Intermountain’s proposed capital structure? 19 A. Intermountain is proposing to establish a capital structure consisting of 50.00 percent 20 common equity and 50.00 percent long-term debt. 21 PAGE 75 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Did you conduct any analysis to determine if this requested equity ratio was 1 reasonable? 2 A. Yes. I reviewed the Company’s proposed capital structure relative to the actual capital 3 structures of the utility operating subsidiaries of the companies in the proxy group. Since 4 the ROE is set based on the return that is derived from the risk-comparable proxy group, 5 it is reasonable to look to the average capital structure for the proxy groups to benchmark 6 the equity ratios for the Company. 7 Please discuss your analysis of the capital structures of the proxy group companies. 8 A. Specifically, I calculated the mean proportions of common equity and long-term debt 9 over the past three years for each of the companies in the proxy group at the operating 10 subsidiary level. Exhibit No. 12 summarizes the actual capital structures of the operating 11 subsidiaries. As shown, the average equity ratios for the operating subsidiaries of the 12 proxy group range from 48.73 percent to 61.47 percent, with a mean of 56.41 percent. 13 Intermountain’s proposed equity ratio of 50.00 percent is well below the mean 14 established by the capital structures of the utility operating subsidiaries of the proxy 15 group. 16 Do you have any additional comments regarding the relationship between the 17 authorized equity ratio and the authorized ROE? 18 A. Yes. There is a direct relationship between the authorized equity ratio and the authorized 19 ROE. In particular, the authorized equity ratio is a primary indicator of financial risk for 20 a regulated utility such as Intermountain. To the extent the authorized equity ratio is 21 reduced, a corresponding increase is necessary in the authorized ROE to compensate 22 investors for the greater financial risk associated with a lower equity ratio. 23 PAGE 76 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS Are there other factors to be considered in setting the Company’s capital structure? 1 A. Yes. The credit rating agencies’ response to the Tax Cuts and Jobs Act of 2017 (TCJA) 2 must also be considered when determining the equity ratio. All three rating agencies 3 have noted that the TCJA has negative implications for utility cash flows. S&P and Fitch 4 specifically identified increasing the equity ratio as one approach to ensure that utilities 5 have sufficient cash flows following the federal income tax rate reductions and the loss of 6 bonus depreciation. As S&P noted “[r]egulators must also recognize that tax reform is a 7 strain on utility credit quality, and we expect companies to request stronger capital 8 structures and other means to offset some of the negative impact.”90 Furthermore, 9 Moody’s downgraded the rating outlook for the entire utilities sector in June 2018 and 10 downgraded the ratings of numerous utilities based in part on the negative effects of the 11 TCJA on cash flows. 12 Most recently, Moody’s revised its 2023 outlook for the utilities sector to 13 “negative” based on ongoing challenges of inflation, increasing interest rates and higher 14 natural gas prices. Moody’s noted that these challenges increase the pressure on customer 15 affordability and the ability of utilities to promptly recover their costs. Moody’s concluded 16 that regulated utilities’ financial metrics are already under pressure with little cushion, and 17 that sustained capital spending is likely as utilities continue progress towards emissions 18 90 Standard & Poor’s Ratings, “U.S. Tax Reform: For Utilities’ Credit Quality, Challenges Abound,” January 24, 2018, at 5. PAGE 77 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS reductions and net-zero goals. Moody’s noted that the outlook could return to stable if 1 regulatory support remains intact.91 2 S&P also continues to maintain a negative outlook for the utility industry in 202292 3 and noted that since downgrades outpaced upgrades for a second consecutive year in 2021 4 for the first time ever the median investor-owned utility credit rating fell to the “BBB” 5 category.93 Further, S&P expects continued pressure on cash flows over the near-term as 6 utilities continue to increase leverage to fund capital expenditure plans necessary to reduce 7 greenhouse gas emission and improve safety and reliability. Finally, S&P also highlighted 8 inflation, higher interest rates and rising commodity prices as additional risks that could 9 further constrain the credit metrics for utilities over the near-term. In regards to inflation 10 S&P noted: 11 Inflation recently spiked to its highest level in decades after rising for 12 several consecutive months in 2021. Given the sustained increase to the 13 U.S. consumer price index in 2021, inflation no longer appears to be just 14 transitory and may have financial implications for the investor-owned North 15 American regulated utility industry. Because of the regulatory lag within 16 the industry, inflation, which causes prices to rise, typically leads to a 17 weakening of financial performance. The regulatory lag is the timing 18 difference between when costs are incurred and when regulators allow those 19 costs to be fully recovered from ratepayers.94 20 The credit ratings agencies’ continued concerns over the negative effects of 21 inflation, and increased capital expenditures underscore the importance of maintaining 22 91 See, e.g., Walton, Robert, “Moody’s adopts negative outlook for regulated utility sector, warns on gas prices, economy and cost recovery,” Utility Dive, November 11, 2022; Bennett, Abbie, “Moody’s revises US regulated utilities outlook to negative,” S&P Capital IQ Pro, November 11, 2022. 92 S&P Global Ratings, “Regulated Utilities: Credit quality has weakened and credit risks are rising,” July 14, 2022. 93 S&P Global Ratings, “For the First Time Ever, the Median Investor-Owned Utility Ratings Falls to the 'BBB' Category,” January 20, 2022. 94 Ibid. PAGE 78 OF 79 A. BULKLEY, DI INTERMOUNTAIN GAS adequate cash flow metrics for the industry, as a whole, and Intermountain, particularly, in 1 the context of this proceeding. 2 What is your conclusion with regard to the Company’s proposed capital structure? 3 A. Considering the actual capital structures of the proxy group operating companies, I 4 believe that Intermountain’s proposed common equity ratio of 50.00 percent is 5 reasonable. The proposed equity ratio is well below the average equity ratio established 6 by the capital structures of the utility operating subsidiaries of the proxy companies, 7 which would suggest that Intermountain has greater financial risk than the proxy group. 8 This proposed capital structure would support an ROE towards the high-end of my 9 recommended ROE range. 10 CONCLUSIONS AND RECOMMENDATION 11 What is your conclusion regarding a fair ROE for Intermountain’s natural gas 12 distribution operations in Idaho? 13 A. Based on the quantitative and qualitative analyses presented in my Direct Testimony, and 14 in light of the business and financial risks of Intermountain as compared to the proxy 15 group, it is my view that an ROE of 10.30 percent on an equity ratio of 50.00 percent 16 would fairly balance the interests of customers and shareholders. This ROE would 17 enable the Company to maintain its financial integrity and therefore its ability to attract 18 capital at reasonable rates under a variety of economic and financial market conditions, 19 while continuing to provide safe, reliable, and affordable gas utility service to customers 20 in Idaho. 21 22 PAGE 79 OF 79 A.
