A. Please state your name and business address. William E. Avera, 3907 Red River, Austin, Texas, 4 78751. 5 6 Q. A. In what capacity are you employed? I am the President of FINCAP, Inc. , a firm 7 providing financial,economic,and policy consulting 8 services to business and government. 9 Q. Please describe your educational background and 10 professional experience.11 A. A description of my background and 12 qualifications, including a resume containing the details 13 of my experience, is attached as Schedule WEA-1. 14 A. Overview 15 16 17 Q.What is the purpose of your testimony in this case? A.The purpose of my testimony is to present to the 18 Idaho Public Utilities Commission (the ~Commission" or 19 ~ IPUC") my independent evaluation of the fair rate of 20 return on equity (~ROE") for the jurisdictional electric 21 and gas utility operations of Avista Corp. ("Avista" or 22 ~the Company").In addition,I also examined the 23 reasonableness of Avista' s capital structure, considering 24 both the specific risks faced by the Company and other 25 industry guidelines. Avera, Di 1 Avista Corporation 1 Q. Please suirize the informtion and materials 2 you relied on to support the opinions and conclusions 3 contained in your testimony. 4 A. To prepare my testimony, I used information from 5 a variety of sources that would normally be relied upon by 6 a person in my capaci ty .I am familiar with the 7 organization, finances, and operations of Avista from my 8 participation in prior proceedings before the I PUC , the 9 Washington Utilities and Transportation Commission, and the 10 Oregon Public Utility Commission.In connection with the 11 present filing, I considered and relied upon corporate 12 disclosures, publicly available financial reports and 13 filings, and other published information relating to 14 Avista.I also reviewed information relating generally to 15 current capital market conditions and specifically to 16 current investor perceptions,requirements,and 17 expectations for Avista' s utility operations.These 18 sources, coupled with my experience in the fields of 19 finance and utility regulation, have given me a working 20 knowledge of this issues relevant to investors' required 21 return for Avista, and they form the basis of my analyses 22 and conclusions. 23 Q. What is the role of the rate of return on common 24 equity in setting a utility's rates? 25 A. The ROE serves to compensate common equity 26 investors for the use of their capital to finance the plant Avera, Di 2 Avista Corporation 1 and equipment necessary to provide utility service. 2 Inves tors commi t capi tal only if they expect to earn a 3 return on their investment commensurate with returns 4 available from alternative investments with comparable 5 risks.To be consistent with sound regulatory economics 6 and the standards set forth by the Supreme Court in the 7 Bluefield1 and Hope2 cases, a utility's allowed ROE should 8 be sufficient to: 1) fairly compensate the utility's 9 investors, 2) enable. the utility to offer a return adequate 10 to attract new capital on reasonable terms, and 3) maintain 11 the utility's financial integrity. 12 13 14 Q. How did you go about developing your conclusions regarding a fair rate of return for Avista? A. I first reviewed the operations and finances of 15 Avista and the general conditions in the utility industry. 16 With this as a background, I conducted various well- 17 accepted quantitative analyses to estimate the current cost 18 of equity,including alternative applications of the 19 discounted cash flow (~DCF") model and the Capital Asset 20 Pricing Model (~CAPMtt), as well as reference to expected 21 earned rates of return for utilities. Based on the cost of 22 equity estimates indicated by my analyses, the Company's 23 ROE was evaluated taking into account the specific risks 1 Bluefield Water Works & Improvement Co. v. Pub. Servo Comm 'n, 262 U.8. 679 (1923).2 Fed. Power Comm 'n v. Hope Natural Gas Co., 320 U. 8. 591 (1944). Avera, Di 3 Avista Corporation 1 and potential challenges for Avista' s utility operations in 2 Idaho. 3 B. Suiry of Conclusions 4 Q. What are your findings regarding the fair rate of 5 return on equity for Avista? 6 A. Based on the results of my analyses and the 7 economic requirements necessary to support continuous 8 access to capital under reasonable terms, I determined that 9 a fair ROE for Avista falls in the range of 10.7 percent to 10 12.2 percent.The bases for my conclusion are surarized 11 below: 12 13 14 15 16 17 18 19 20 . In order to reflect the risks and prospects associated with Avista' s jurisdictional utility operations, my analyses focused on a proxy group of twenty other utilities with comparable investment risks. Consistent with the fact that utilities must compete for capital with firms outside their own industry, I also referenced a proxy group of comparable risk companies in the non-utility sector of the economy; 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 . Because investors' required return on equity is unobservable and no single method should be viewed in isolation, I applied both the discounted cash flow (~DCF") and capital asset pricing model (~CAPM") methods, as well as the expected earnings approach, to estimate a fair ROE for Avista: o My application of the constant growth DCF model considered four alternative growth measures based on proj ected earnings growth, as well as the sustainable, ~br+sv" growth rate for each firm in the respective proxy groups; o After eliminating low- and high-end outliers, my DCF analyses implied a cost of equity of 10.7 percent for the proxy group of utilitiesand 12.6 percent for the group of non-utility companies; Avera, Di 4 Avista Corporation 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 o Application of the CAPM approach using forward- looking data that best reflects the underlying assumptions of this approach implied a cost of equity of 12.2 percent for the utility proxy group and 11.4 percent for the firms in the non-utility proxy group; o Applying the CAPM method using historical realized rates of return resulted in a cost of equity of 10.7 percent for the utility proxygroup and 10.0 percent for the non-utility proxy group;o My evaluation of earned rates of return expected for utilities suggested a cost of equi ty on the order of 11.0 percent; o Based on these results, I concluded that the cost of equity for the proxy groups of electric utilities and non-utility companies is in the 10.7 percent to 12.2 percent range. 19 Considering investors'expectations for capital 20 markets and the need to support financial integrity and 21 fund crucial capital investment even under adverse 22 circumstances, I concluded that Avista' s requested ROE of 23 10.8 percent is reasonable.Based on my evaluation, I 24 determined that: 25 26 27 28 . Because Avista' s requested ROE of 10.8 percent barely exceeds the lower bound of my recommended range, it represents a conservative estimate of investors' required rate of return; 29 30 31 32 33 34 35 36 37 38 39 40 . The reasonableness of a 10.8 percent minimum ROE for Avista is also supported by the need to consider the Company's credit standing, which remains relatively weak: o The pressures of funding significant capitalexpenditures and increased operating risks heighten the uncertainties associated withAvista; o Because of Avista' s reliance on hydroelectric generation, the Company is exposed to relatively greater risks of power costvolatility; Avera, Di 5 Avista Corporation 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 o Investors view the Power Cost Adjustment Mechanism ( \\ PCA" ) as supportive of the Company's financial integri ty, but they understand that the PCA does not apply to 100percent of power costs; nor does it insulate Avista from the need to finance accrued power production and supply costs or shield theCompany from potential regulatorydisallowances; o Given Avista' s present credit ratings, an inadequate rate of return imposed in this proceeding would further pressure the Company's financial flexibility and credit standing; o My conclusion that a 10.8 percent ROE for Avista is a conservative estimate of investors' required return is also reinforced by the Company's relatively greater risks as comparedwith the proxy group, the greater uncertainties associated with Avista' s relatively small size, and the fact that my recommended ROE range doesnot consider flotation costs. 22 23 Q. What is your conclusion as to the reasonableness 24 of the Company's capital structure? 25 A. Based on my evaluation, I concluded that a common 26 equi ty ratio of 47.94 percent represents a reasonable basis 27 from which to calculate Avista' s overall rate of return. 28 This conclusion was based on the following findings: 29 . Avista' s requested capitalization is consistent30 with the Company's need to strengthen its credit31 standing and financial flexibility as it seeks to32 raise additional capital to fund significant system33 investments and meet the requirements of its34 service territory; 35 36 37 38 39 . Avista' s proposed common equity ratio is entirely consistent with the 47.8 percent and 49.0 percent average equity ratio maintained by the firms in my utility proxy group, based on year-end 2007 data and near-term expectations, respectively. Avera, Di 6 Avista Corporation 1 2 3 4 5 6 7 . My conclusion is reinforced by the investment community's focus on the need for a greater equity cushion to accommodate higher operating risks andthe pressures of funding significant capital investments, as well as the impact of off-balance sheet commi tments such as purchased poweragreements. 8 Q. What other evidence did you consider in 9 evaluating your recommendation in this case? 10 A. My recommendation was reinforced by the following 11 findings: 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 .Sensitivity to regulatory uncertainties has increased dramatically and investors recognize that constructive regulation is a key ingredient in supporting utility credit standing andfinancial integrity; Providing Avista with the opportunity to earn a return that reflects these realities is an essential ingredient to strengthen the Company's financial position, which ultimately benefits customers by ensuring reliable service at lowerlong-run cos ts ; My conclusion is reinforced by the economicreali ty that Avista' s actual returns have fallen systematically short of the allowed ROE; and the financial impact of an ROE below the minimum level requested by Avista would threaten the Company's ability to maintain an investment grade creditrating; Investors are aware of the near-term challenges posed by upward pressure on costs and rising capital expenditures. For Avista, these concerns are magnified by the fact that financial metrics continue to be anemic and its credit standing, accordingly, remains relatively weak; Regulatory support, including a reasonable ROE, will be a key driver in securing additional progress towards restoring the Company's financial heal th. Further strengthening Avista' s financial integrity is imperative to ensure that the Company has the capability to maintain an investment grade rating while confronting potential challenges . . . .

What is the purpose of this section? 5 A. As a predicate to my economic and capital market 6 analyses, this section examines the investment risks that 7 investors consider in evaluating their required rate of 8 return for Avista. 9 A. Operations & Finances 10 11 Q. A. Briefly describe Avista. Avista is engaged primarily in the procurement, 12 transmission, and distribution of natural gas and electric 13 energy.Avista's generating facilities include 8 14 hydroelectric generating stations with a combined capacity 15 of approximately 980 megawatts (~MW") and the electrical 16 output of these plants, which has a significant impact on 17 total energy costs, is dependent on streamflows. Although 18 Avista estimates that. hydroelectric generation is capable 19 of supplying approximately 50 percent of total system 20 requirements under normal conditions, the Company has 21 experienced prolonged periods of persistent below-normal 22 water conditions in the past. 23 Because close to one-half of Avista' s total energy 24 requirements are provided by hydroelectric facilities, the 25 Company is exposed to a level of uncertainty not faced by 26 most utilities.While hydropower confers advantages in Avera, Di 8 Avista Corporation 1 terms of fuel cost savings and di vers i ty ,reduced 2 hydroelectric generation due to below-average water 3 condi tions forces Avista to rely more heavily on wholesale 4 power markets or more costly thermal generating capacity to 5 meet its resource needs. As S&P recently observed: 6 7 8 9 10 11 12 13 14 15 16 A reduction in hydro generation typically increases an electric utility's costs by requiring it to buy replacement power or run more expensive generation to serve customer loads. Low hydro generation can also reduce utilities' opportunity to make off-system sales. At thesame time, low hydro years increase regional wholesale power prices, creating potentially a double impact - companies have to buy more powerthan under normal conditions, paying higher. 3prices. 17 Additionally, all but one of Avista's hydroelectric 18 facilities are subject to licensing under the Federal Power 19 Act, which is administered by FERC.After agreeing to 20 institute various protections, mitigation, and enhancement 21 measures in order to address environmental concerns, Avista 22 received new 45-year operating licenses covering its two 23 largest hydroelectric facilities - Cabinet Gorge and Noxon 24 Rapids - in 2001.The license covering five hydroelectric 25 plants on the Spokane River expired in August 2007, with an 26 annual permit being issued to temporarily extend the 27 current license.Relicensing is not automatic under 28 federal law, and Avista must demonstrate that it has 3 Standard & Poor's Corporation, uPacific Northwest Hydrology And Its Impact On Investor-Owed Utilities' Credit Quality, II RatingsDirect (Jan. 28, 2008). Avera, Di 9 Avista Corporation 1 operated its facilities in the public interest, which 2 includes adequately addressing environmental concerns. 3 4 5 6 Q. How are fluctuations in expenses caused by varying hydro conditions accommdated in its rates? Avista's operating and power market A. Under the PCA, Avista's Idaho jurisdictional 7 rates are adjusted periodically to reflect changes in 8 variable power production and supply costs.When 10 rise above those included in base rates, the PCA allows 9 hydroelectric generation is reduced and power supply costs 11 Avista to increase rates to recover a portion of its 12 additional costs.Conversely, if increased hydroelectric 13 generation were to lead to lower power supply costs, rates 14 would be reduced.Although the PCA provides for rates to 15 be adjusted periodically, it applies to 90 percent of the 16 deviation between actual power supply costs and normalized 17 rates. 18 Q. Does the PCA completely eliminate the risk 19 associated with fluctuations in power supply costs? 20 A. No. The PCA is viewed as supportive of the 21 22 constructive regulation, but it does not apply to 100 Company's financial integrity and example of 23 an 24 utilities with permanent energy cost adjustment mechanisms percent of Avista' s power costs.Moreover, even for 25 in place, there can be a significant lag between the time 26 the utility actually incurs the expenditure and when it is Avera, Di 10 Avista Corporation 1 recovered from ratepayers.The PCA does not insulate 2 Avista from the need to finance deferred power production 3 and supply costs, with Moody's observing, ~The historical 4 financial metrics for Avista have been pressured by debt 5 added to fund energy cost deferrals during times when 6 drought conditions prevailed and this has caused us to 7 consider the metrics in line with the Ba rating category. "4 8 Moreover, even with a PCA, investors recognize the ongoing 9 potential for regulatory disallowances if the Commission 10 determines that the amounts were not prudently incurred. 11 Q. Are there other mechanisms that affect Avista's 12 Idaho jurisdictional rates for utility service?13 A. Yes. With respect to its Idaho gas utility 14 operations, Avista is allowed to adjust natural gas rates 15 to reflect the difference between actual purchased natural 16 gas costs and amounts collected through rates under a 17 Purchased Gas Adjustment (~PGA") clause. 18 Q. Does Avista anticipate the need to access the 19 capital markets going forward?20 A. Most definitely. Avista will require capital 21 investment to meet customer growth, provide for necessary 22 maintenance and replacements of its natural gas utility 23 systems, as well as fund new investment in electric 24 generation, transmission and distribution facilities.As · Moody's Investors Service, UCredit Opinion: Avista Corp., II Global Credit Qpinion (Dec. 21, 2007). Avera, Di 11 Avista Corporation 1 discussed by Company witness Mr. Malquist, planned capital 2 expenditures for 200S total approximately $190 million, and 3 approximately $200 million annually going forward.in 4 addition to funding investment in utility infrastructure, 5 Avista will also be required to refinance $31S million of 6 its long-term debt outstanding in 200S and will need to 7 issue new securities to fund a significant portion of these S requirements. 9 Continued support for Avista's financial integrity and 10 flexibility will be instrumental in attracting the capital 11 necessary to fund these projects in an effective manner. 12 Similarly, bolstering Avista' s financial position will also 13 support the Company's efforts to refinance securities at 14 favorable terms, thereby lowering costs for customers in 15 the future.Avista's reliance on purchased power to meet 16 shortfalls in hydroelectric generation magnifies the 17 importance of strengthening financial flexibility, which is 1S essential to guarantee access to the cash resources and 19 interim financing required to cover inadequate operating 20 cash flows, as well as fund required investments in the 21 utility system. 22 23 Q. A. What credit ratings have been assigned to Avista? Standard & Poor's Corporation (~S&P") recently 24 raised the Company's corporate credit rating from ~BB+" to 25 ~BBB-~, in large part due to improved financial metrics Avera, Di 12 Avista Corporation 1 resulting from the settlement of Avista' s last general rate 2 case in Washington. 5 Similarly, Moody's Investors Service 3 (~Moody' s") upgraded Avista' s issuer credit rating from 4 "Ba1" to ~Baa3" in December 2007.6 Fitch Ratings, Ltd. 5 ("Fitch") upgraded its issuer default rating for Avìsta one 6 notch to ~BB+", and has assigned the Company a ~positive 7 Outlook", indicating the potential for higher ratings going 8 forward. 7 The ratings assigned by S&P and Moody's 9 represent the lowest rung on the ladder of the investment 10 grade scale. 11 Q. How have investors' risk perceptions for firms 12 involved in the utility industry evolved? 13 A. Implementation of structural change and related 14 events caused investors to rethink their assessment of the 15 relative risks associated with the utility industry.The 16 past decade witnessed steady erosion in credit quality 17 throughout the utility industry, both as a result of 18 revised perceptions of the risks in the industry and the 19 weakened finances of the utilities themselves.S&P 20 recently reported that the majority of the companies in the 5 Standard & Poor's Corporation, UAvista Corp.'s Corporate Credit Rating Raised One Notch To 'BBB-', II RatingsDirect (Feb. 7, 2008).6 Moody's Investors Service, uCredi t Opinion: Avista Corp., II Global Credit Research (Dec. 21, 2007).7 Fitch Ratings, Ltd, UFitch Upgrades Avista Corp.'s IDR to 'BB+' from 'BB'; Outlook positive, II Press Release (Aug. 9, 2007).

"10 7 8 9 Q. Is the potential for energy market volatility an ongoing concern for investors? A.Most definitely.Investors recognize the ongoing prospect for further turmoil in energy markets.S&P has 11 reported continued spikes in wholesale market prices, 11 with 12 13 contribute to a ~challenging environment" for electric Fitch noting that ~elevated energy commodity prices" 14 utili ties. 12 Similarly, the FERC Commission Staff has 15 continued to recognize the ongoing potential for market 16 disruption in the West, as a 2007 market assessment report 17 concluded: 18 Prices are likely to remain a concern.

S. Department of 10 Energy, reported that average delivered coal prices for 11 12 13 14 15 16 17 18 19 20 electric utilities increased 9.7 percent in 2006, the sixth consecutive annual rise.19 Q. What are the key uncertainties considered by investors in assessing their required rate of return for Avista? A. Because close to one-half of Avista' s total energy requirements provided by hydroelectricare facili ties,the Company is exposed to a level of uncertainty not faced by most utilities.Investors 21 stream flows, and Avista' s reliance on wholesale purchases recognize that volatile energy markets,unpredictable 22 to meet a significant portion of its resource needs can 23 expose the Company to the risk of reduced cash flows and 24 unrecovered power supply costs. S&P cited this exposure as 18 Standard & Poor's Corporation, uRising Coal Prices May Threaten U. S. Utility Credit Profiles," RatingsDirect (Aug. 12, 2004).19 Energy Information Administration, Annual Coal Report 2006 at 9 (Nov. 2007). Avera, Di 16 Avista Corporation 1 the ~key utility risk"confronting the 20Company,and 2 concluded that Avista, along with Idaho Power Company, 3 "face the most substantial risks despite their PCAs and 4 d h. 21cost-up ate mec anisms."Similarly, Fitch concluded, ~The 5 potential negative cash flow impact from a prolonged period 6 of below normal hydro conditions and high natural gas 7 prices are primary sources of concern"for Avista' s 8 inves tors. 22 9 In addition, investors are aware of the financial and 10 regulatory pressures faced by utilities associated with 11 rising costs and the need to undertake significant capital 12 investments. As Moody's observed: 13 14 15 16 17 18 19 20 (T) here are concerns arising from the sector's sizeable infrastructure investment plans in the face of an environment of steadily rising operating costs. Combined, these costs and investments can create a continuous need for regulatory rate relief, which in turn can increase the likelihood for political and/or regulatory intervention. 23 21 Similarly, S&P noted that ~onerous construction programs", 22 along with rising operating and maintenance costs and 23 volatile fuel costs, were a significant challenge to the 20 Standard & Poor's Corporation, UAvista Corp.'s Corporate Credit Rating Raised One Notch to 'BBB-'," RatingsDirect (Feb. 7, 2008).21 Standard & Poor' sCorporation, uPacific Northwest Hydrology And Its Impact On Investor-Owed Utilities' Credit Quality," RatingsDirect (Jan. 28, 2008).22 Fitch Ratings, Ltd., "Fitch Affirms Avista Corp.'s IDR at 'BB+'; Outlook positive," Press Release (Feb. 6, 2008).23 Moody's Investors Service, UStorm Clouds Gathering on the Horizon for the North American Electric Utility Sector," Special Comment (Aug. 2007) . Avera, Di 17 Avista Corporation 1 utility . d 24in ustry.Moody's recently echoed this 2 assessment, concluding, ~There are significant negative 3 trends developing over the longer-term horizon. "25 4 While providing the infrastructure necessary to meet 5 the energy needs of customers is certainly desirable, it 6 imposes additional financial responsibilities on Avista. 7 As noted earlier, the Company's plans include capital 8 expendi tures of approximately $200 million annually, 9 including enhancements to its transmission and distribution 10 system and investment in generating resources.Investors 11 are aware that the challenge of achieving timely regulatory 12 recovery associated with rising costs and burdensome 13 capital expenditure requirements impacts Avista's ability 14 to earn a fair rate of return. 15 16 17 Q.What other considerations affect investors' evaluation of Avista? A. Avista and other utilities are confronting 18 increased environmental pressures that could impose 19 significant uncertainties and costs.In 2007 S&P cited 20 environmental mandates, including emissions, conservation, 24 Standard & Poor's Corporation, uu.

"29 Q. Does Avista also face additional risks because of the impact of industry restructuring on transmission operations? A.Yes.Policy evolution in the transmission area has been wide reaching and Avista must address changes in 22 the electric transmission function of its business.

Would investors consider Avista's relative size in their assessment of the Comany's risks and prospects? A. Yes. A firm's relative size has important 11 implications for investors in their evaluation of 12 alternative investments, and it is well established that 13 smaller firms are more risky than larger firms.With a 14 market capitalization of approximately $1.1 billion, Avista 15 is one of the smallest publicly traded electric utili ties 16 followed by Value Line,which have an average 17 capitalization of approximately $8.1 billion.31 18 The magnitude of the size disparity between Avista and 19 other firms in the utility industry has important practical 20 implications with respect to the risks faced by investors. 21 All else being equal, it is well accepted that smaller 22 firms are more risky than their larger counterparts, due in 23 part to their relative lack of diversification and lower 30 Standard & Poor's Corporation, "Capital Spending On Electric Transmission Is On The Upswing Around The World," RatingsDirect (Aug. 7, 2006).31 ww.valueline.com (Retrieved Feb. 13, 2008).

B. capital Structure Q. Is an evaluation of the capital structure maintained by a utility relevant in assessing its return on equity? A. Yes. Other things equal, a higher debt ratio, or 16 financial risk for all investors. A greater amount of debt lower common equity ratio,translates into increased 17 means more investors have a senior claim on available cash 18 flow, thereby reducing the certainty that each will receive 19 his contractual paYfents.This increases the risks to 20 which lenders are exposed, and they require correspondingly 21 higher rates of interest.From common shareholders' 32 It is well established in the financial literature that smaller firms are more risky than larger firms. See, e.g., Eugene F. Fama and Kenneth R. French, "The Cross-Section of Expected Stock Returns", The Journal of Finance (June 1992); George E. Pinches, J. Clay Singleton, and Ali Jahankhani, "Fixed Coverage as a Determinant of Electric Utility Bond Ratings", Financial Management (Sumer 1978).33 See for example Rolf W. Banz, "The Relationship Between Return and Market Value of Common Stocks", Journal of Financial Economics (Septemer 1981) at 16. Avera, Di 21 Avista Corporation 1 standpoint, a higher debt ratio means that there are 2 proportionately more investors ahead of them, thereby 3 increasing the uncertainty as to the amount of cash flow, 4 if any, that will remain. 5 6 7 Q. requested A. What common equity ratio is implicit in Avista's capi tal structure? Avista's capital structure is presented in the 8 testimony of Mr. Malquist. As surarized in his testimony, 9 the pro-forma common equity ratio used to compute Avista' s 10 overall rate of return was 47.94 percent in this filing. 11 Q. What was the average capitalization maintained by 12 the utility proxy group? 13 A. As shown on Schedule WEA-3, for the twenty firms 14 in the utility proxy group, common equity ratios at 15 December 31, 2007 ranged between 40.1 percent and 57.9 16 percent and averaged 47.8 percent. 17 Q. What capitalization is representative for the 18 proxy group of utilities going forward? 19 A. As shown on Schedule WEA-3, The Value Line 20 Investment Survey (~Value Line") expects an average common 21 equity ratio for the proxy group of utilities of 49.0 22 percent for its three-to-five year forecast horizon, with 23 the individual common equity ratios ranging from 42.5 24 percent to 60.5 percent. Avera, Di 22 Avis ta Corporation 1 Q. How does Avista' s common equity ratio compare 2 with those maintained by the reference group of utilities? 3 A. The 47.94 percent common equity ratio requested 4 by Avista is entirely consistent with the 47.8 percent and 5 49.0 percent average equity ratios for the firms in the 6 proxy group at year-end 2007 and based on Value Line's 7 near-term expectations , respectively. 8 Q. What implication does the increasing risk of the 9 utility industry have for the capital structures maintained 10 by utilities? 11 A. As discussed earlier, the average credit rating 12 associated with firms in the electric industry has fallen 13 to triple-B, with Avista's "BBB-~ rating occupying the 14 lowest rung on the ladder of the investment grade scale. 15 At the same time, electric utili ties are facing rising cost 16 structures,the need to finance significant capital 17 investment plans, uncertainties over accommodating future 18 environmental mandates,and ongoing regulatory risks. 19 Coupled with the decline in credit quality,these 20 considerations warrant a stronger balance sheet to deal 21 wi th an increas ingly uncertain and competi ti ve market.A 22 more conservative financial profile, in the form of a 23 higher common equity ratio, is consistent with increasing 24 uncertainties and the need to maintain the continuous 25 access to capital that is required to fund operations and 26 necessary system investment, even during times of adverse Avera, Di 23 Avista Corporation 1 capi tal market condi tions .This is especially the case if 2 electric utilities are to be successful in raising the 3 substantial funds necessary to boost investments for 4 network reliability. 5 Moody's has warned investors of the risks associated 6 with debt leverage and fixed obligations and advised 7 utilities not to squander the opportunity to strengthen the 8 balance sheet as a buffer against future uncertainties. 34 9 Moody's recently noted that, absent a stronger equity 10 cushion, utilities would be faced with lower credit ratings 11 in the face of rising business and operating risks: 12 There are significant negative trends developing13 over the longer-term horizon. This developing14 negative concern primarily relates to our view15 that the sector's overall business and operating16 risks are rising - at an increasingly fast pace -17 but that the overall financial profile remains18 relatively steady. A rising risk profile19 accompanied by a relatively stable balance sheet20 profile would ultimately result in credit quality 21 deterioration. 35 22 This is especially the case for electric utilities that are 23 exposed to the potential for significant fluctuations in 24 power supply costs, such as Avista. 34 Moody's Investors Service, UStorm Clouds Gathering on the Horizon for the North American Electric Utility Sector," Special Comment (Aug. 2007) .35 Moody's Investors Service, "u. S. Electric Utility Sector," Industry Outlook (Jan. 2008). Avera, Di 24 Avista Corporation 1 2 3 Q. What other factors do investors consider in their assessment of a company's capital structure? A. Depending on their specific attributes, 4 contractual agreements or other obligations that require 5 the utility to make specified paYfents may be treated as 6 debt in evaluating Avista' s financial risk.Because power 7 purchase agreements (~PPAs") and leases typically obligate 8 the utility to make specified minimum contractual paYfents 9 akin to those associated with traditional debt financing, 10 investors consider a portion of these commitments as debt 11 in evaluating total financial risks.Because investors 12 consider the debt impact of such fixed obligations in 13 assessing a utility's financial position,they imply 14 greater risk and reduced financial flexibility.In order 15 to offset the debt equivalent associated with off-balance 16 sheet obligations, the utility must rebalance its capital 17 structure by increasing its common equity in order to 18 restore its effective capitalization ratios to previous 19 levels. 36 20 Reflecting the longstanding perception of investors 21 that the fixed obligations associated with PPAs, leases, 22 and other off-balance sheet obligations diminish a 23 utility's creditworthiness and financial flexibility, the 36 The capital structure ratios presented earlier do not include imputed debt associated with power purchase agreements or the impact of other off-balance sheet obligations. Avera, Di 25 Avista Corporation 1 implications of these commitments have been repeatedly 2 ci ted by maj or bond rating agencies in connection with 3 assessments of utility financial risks.For example, in 4 explaining its evaluation of the credit implications of 5 PPAs, S&P affirmed its position that such agreements give 6 rise to ~debt equivalents" and that the increased financial 7 risk must be considered in evaluating a utility's credit 8 risks. 37 As the rating' agency explained: 9 10 11 12 13 14 15 16 17 18 19 20 21 22 For many years, Standard & Poor's Ratings Services has viewed power supply agreements (PPA) in the U. S. utility sector as creating fixed, debt-like, financial obligations that represent substitutes for debt-financed capital investments in generation capacity. In a sense, a utility that has entered into a PPA has contracted with a supplier to make the financial investment on its behalf. Consequently, PPA fixed obligations, in the form of capacity paYfents, merit inclusion in a utility's financial metrics as though they are part of a utility's permanent capital structure and are incorporated in our assessment of a utility's creditworthiness. 38 23 Apart from reaffirming the importance of imputed debt in 24 its analysis of credit standing, S&P also noted that it has 25 refined its methodology to include imputed debt associated 26 with shorter-term PPAs. 39 Similarly, S&P recently affirmed 27 its policy of modifying a utility's balance sheet to 37 Standard & Poor's Corporation, u Standard & Poor's Methodology For Imputing Debt For U.S. Utilities' Power Purchase Agreements," RatingsDirect (May 7, 2007).38 Id. 39 Id. Avera, Di 26 Avista Corporation 10 1 include the debt equivalents associated with operating 2 leases. 40 3 As discussed earlier, a significant portion of the 4 Company's power requirements are currently obtained through 5 purchased power contracts.These contractual paYfent 6 obligations, along with operating leases and obligations 7 associated with postretirement benefits,fixedare 8 commitments with debt-like characteristics and are properly 9 considered when evaluating the financial risks implied by Avista's capital structure.S&P reported that it adjusts 11 Avista' s capitalization to include approximately $226 12 13 million in imputed debt from off-balance sheet bl' . 41o igations.Unless the Company takes action to offset 14 this additional financial risk by maintaining a higher 15 equity ratio, the resulting leverage will weaken Avista's 16 17 18 19 20 21 creditworthiness, implying a higher required rate of return to compensate investors for the greater risks. 42 Q. What did you conclude with respect to the Company's capital structure? A. Based on my evaluation, I concluded that Avista' s requested capital structure represents a reasonable mix of 40 Standard & Poor's Corporation, "Implications Of Operating Leases On Analysis Of u.s. Electric Utilities," RatingsDirect (Jan. 15, 2008).41 Standard & Poor's Corporation, "Avista Corp.," RatingsDirect (Aug. 1, 2007).42 Apart from the immediate impact that the fixed obligation of purchased power costs has on the utility's financial risk, higher fixed charges also reduce ongoing financial flexibility, and the utility may face other uncertainties, such as potential replacement power costs in the event of supply disruption. Avera, Di 27 Avista Corporation 1 capital sources from which to calculate the Company's 2 overall rate of return.Avista's requested common equity 3 ratio is entirely consistent with the average capital 4 structure for the utility proxy group, based on year-end 5 2007 data and Value Line's near-term projections. 6 While industry averages provide one benchmark for 7 comparison, each firm must select its capitalization based 8 on the risks and prospects it faces, as well its specific 9 needs to access the capital markets. A public utility with 10 an obligation to serve must maintain ready access to 11 capital under reasonable terms so that it can meet the 12 service requirements of its customers. The need for access 13 becomes even more important when the company has capital 14 requirements over a period of years, and financing must be 15 continuously available, even during unfavorable capital 16 market conditions. 17 Avista's capital structure reflects the Company's 18 ongoing efforts to strengthen its credit standing and 19 support access to capital on reasonable terms.As 20 indicated earlier, the challenges posed by significant 21 capi tal requirements, volatile energy prices, and reliance 22 on hydro generation and wholesale markets magnifies the 23 importance of preserving financial flexibility.Moody's 24 observed that Avista's financial metrics have been 25 pressured by the need to finance power cost deferrals Avera, Di 28 Avista Corporation 1 during low-water years,and noted that its ratings 2 anticipate ~conservative financing strategies. ,,43 Financial 3 flexibili ty plays a crucial role in ensuring the 4 wherewithal to meet the needs of customers, and utilities 5 wi th higher leverage may be foreclosed from addi tional 6 borrowing, especially during times of stress.In this 7 regard, Avista' s equity ratio reflects the challenges posed 8 by its resource mix, as well as the burden of significant 9 capital spending requirements. 10 III. CAPITAL MAT ESTIMATES 11 12 Q. A. What is the purpose of this section? This section presents capital market estimates of 13 the cost of equity.The details of my quantitative 14 analyses are contained in Schedule WEA-2, with the results 15 being sumarized below. 16 A. Overview 17 18 19 Q. What role does the rate of equity play in a utility's rates? A. The return on common equity return on common is the cost of 20 inducing' and retaining investment in the utility's physical 21 plant and assets.This investment is necessary to finance 22 the asset base needed to provide utility service. 23 Investors will commit money to a particular investment only 43 Moody's Investors Service, UCredit Opinion: Avista Corp.," Global Credit Research (Dec. 21, 2007). Avera, Di 29 Avista Corporation 1 if they expect it to produce a return commensurate with 2 those from other investments with comparable risks. 3 Moreover, the return on common equity is integral in 4 achieving the sound regulatory objectives of rates that are 5 sufficient to: 1) fairly compensate capital investment in 6 the utility, 2) enable the utility to offer a return 7 adequate to attract new capital on reasonable terms, and 3) 8 maintain the utility's financial integrity. Meeting these 9 objectives allows the utility to fulfill its obligation to 10 provide reliable service while meeting the needs of 11 customers through necessary system expansion. 12 Q. Did you rely on a single method to estimate the 13 cost of equity for Avista? 14 A. No. In my opinion, no single method or model 15 should be relied upon to determine a utility's cost of 16 equity because no single approach can be regarded as wholly 17 reliable.As the Federal Communications Commission 18 recognized: 19 Equity prices are established in highly volatile20 and uncertain capital markets. Different 21 forecasting methodologies compete with each other 22 for eminence, only to be superceded by other23 methodologies as conditions change. . .. In these24 circumstances, we should not restrict ourselves 25 to one methodology, or even a series of26 methodologies, that would be applied27 mechanically. Instead, we conclude that we Avera, Di 30 Avista Corporation 1 2 should adopt a more accommodating and flexible.. 44position. 3 Therefore, I used both the DCF and CAPM methods to estimate 4 the cost of equity.In addition, I also evaluated a fair 5 ROE return us ing an earnings approach based on inves tors' 6 current expectations in the capital markets.In my 7 opinion, comparing estimates produced by one method with 8 those produced by other approaches ensures tha t the 9 estimates of the cost of equity pass fundamental tests of 10 reasonableness and economic logic. 11 Q. What was your conclusion regarding a fair rate of 12 return on equity for the proxy companies? 13 A. Based on the results of my quantitative analyses, 14 and my assessment of the relative strengths and weaknesses 15 inherent in each method, I concluded that the cost of 16 17 18 19 20 21 22 23 24 equity for the proxy companies is in the 10.7 percent 12.2 percent range. B. Results of Quantitative Anlyses Q. How did you define the proxy groups you used to implement the DCF model? A. In estimating the cost of equity, the DCF model is typically applied to publicly traded firms engaged in similar business activities or with comparable investment risks.As described in detail in Schedule No. WEA-2, I 44 Federal Communications Commission, Report and Order 42-43, CC Docket No. 92-133 (1995). Avera, Di 31 Avista Corporation 1 applied the DCF model to a utility proxy group composed of 2 those dividend-paying companies included by Value Line in 3 its Electric Utilities Industry groups with:(1) S&P 4 corporate credit ratings between ~BBB-" and "BBB+," (2) a 5 Value Line Safety Rank of ~2tt or ~3tt, (3) a Value Line 6 Financial Strength Rating of ~B+" to ~B++" , and (4) 7 published growth estimates from IBES,45 Value Line, Reuters, 8 Inc. (~Reuters"), and Zacks Investment Research (~Zacks"). 9 I excluded two companies that otherwise would have been in 10 the proxy group because they are in the process of being 11 acquired. 12 Under the regulatory standards established by Hope and 13 Bluefield,the salient criteria in establishing a 14 meaningful benchmark to evaluate a fair rate of return is 15 relative risk, not the particular business activity or 16 degree of regulation.Consistent with this accepted 17 regulatory standard, I also applied the DCF model to a 18 reference group of comparable risk companies in the non- 19 utility sector of the economy. My assessment of comparable 20 risk relied on three objective benchmarks for the risks 21 associated with common stocks -- Value Line's Safety Rank, 22 Financial Strength rating, and beta. My non-utility proxy 23 group was composed of those U. S. companies followed by 45 IBES growth rates are compiled and reported by Thompson Financial, an arm of The Thompson Corporation, which also publishes consensussecuri ties analyst growth rates under the First Call brand. Avera, Di 32 Avista Corporation 8 9 10 11 12 13 14 15 1 Value Line that 1) pay common dividends, 2) have a Safety 2 Rank of ~ 1", 3) have a Financial Strength Rating of ~A" or 3 above, 4) have beta values of 0.90 or less,46 and 5) have 4 published data from IBES, Value Line, Reuters, and Zacks. 5 6 Consistent with the development of my utility proxy group, I also eliminated firms with below-investment grade credit 7 ratings. Q. How do the overall risks of your proxy groups compare with Avista? A. As shown below, Table 1 compares the non-utility proxy group with the utility proxy group and Avista across four key indicators of investment risk: TABLE 1 COMPARISON OF RISK INDICATORS S&P Value Line Credit Safety Financial Rating Rak Strength ~ Non-Utility Group A+i A+0.80 Utility Proxy Group BBB 3 B++0.89 Avista Corp.BBB-3 B+0.95 16 Considered together, a comparison of these objective 17 measures indicates that the risks investors associate with 18 19 result, the cost of equity estimates indicated by my Avista generally exceed those of the proxy groups.As a 46 This threshold corresponds to the average beta of 0.89 for the utili ty proxy group discussed earlier. Avera, Di 33 Avista Corporation 1 analyses provide a conservative estimate of investors' 2 required rate of return for Avista. 3 Q. What cost of equity is implied by your DCF 4 resul ts for the utility proxy group? 5 A. My application of the DCF model, which is 6 discussed in greater detail in Schedule No. WEA-2, 7 considered four alternative measures of expected earnings 8 growth, as well as the sustainable growth rate based on the 9 relationship between expected retained earnings and earned 10 rates of return ("br + sv").As shown on Schedule WEA-4 11 and sumarized below in Table 2,after eliminating 12 illogical low- and high-end values, application of the 13 constant growth DCF model resulted in the following cost of 14 equity estimates:15 TABLE 2 16 DCF RESULTS - UTILITY PROXY GROUP Growth Rate IBES Value LineReuters Zacks br+sv Average Cost of Equity 11'.3% 10.4% 10.6% 10.9% 9.2% 17 18 Taken together, and considering the relative strengths and 19 weaknesses associated with the alternative growth measures, 20 I concluded that the constant growth DCF results for the 21 utility proxy group implied a cost of equity of 10.8 22 percent. Avera, Di 34 Avista Corporation 1 2 3 Q. What were the results of your DCF analysis for the non-utility reference group? A. As shown on Schedule WEA-6, I applied the DCF 4 model to the non-utility companies in exactly the same 5 manner described earlier for the utility proxy group.As 6 surarized below in Table 3, after eliminating illogical 7 low- and high-end values, application of the constant 8 growth DCF model resulted in the following cost of equity 9 estimates:10 TABLE 311 DCF RESULTS - NON-UTILITY GROUP Growth Rate IBES Value LineReuters Zacks br+sv Average Cost of Equity 12.9% 12.2% 12.5% 12.7% 13.0% 12 13 Based on my assessment of these results, I concluded that 14 the constant growth DCF results for the non-utility proxy 15 group implied a cost of equity of 12.6 percent. 16 Q.Do you believe the constant growth DCF model 17 should be relied on exclusively to evaluate a reasonable 18 19 ROE for Avista? A. No.Because the cost of equity is unobservable, 20 no single method should be viewed in isolation. While the 21 DCF model has been routinely relied on in regulatory 22 proceedings as one guide to investors' required return, it 23 is a blunt tool that should not be used exclusively. Avera, Di 35 Avista Corporation 1 Regulators have customarily considered the results of 2 alternative approaches in determining allowed returns. 47 It 3 is widely recognized that no single method can be regarded 4 as a panacea; all approaches having their own advantages 5 and shortcomings.For example, a publication of the 6 society of Utility and Financial Analysts (formerly the 7 National Society of Rate of Return Analysts), concluded 8 that: 9 Each model requires the exercise of judgment as 10 to the reasonableness of the underlying 11 assumptions of the methodology and on the12 reasonableness of the proxies used to validate13 the theory. Each model has its own way of14 examining investor behavior, its own premises,15 and its own set of simplifications of reality. 16 Each method proceeds from different fundamental17 premises, most of which cannot be validated18 empirically. Investors clearly do not subscribe19 to any singular method, nor does the stock price20 reflect the application of anyone single method21 by investors. 48 22 Moreover, evidence suggests that reliance on the DCF 23 model as a tool for estimating investors' required rate of 24 return has declined outside the regulatory sphere, with the 25 CAPM being ~the dominant model for estimating the cost of 47 For example, a NARUC survey reported that 26 regulatory jurisdictions ascribe to no specific method for setting allowed ROEs, with the results of all approaches being considered. "Utility Regulatory Policy in the U.S. and Canada, 1995-1996," National Association of Regulatory Utility Commissioners (Decemer 1996).4B Parcell, David C., "The Cost of Capital - A Practitioner's Guide," Society of Utility and Regulatory Financial Analysts (1997) at Part 2, p. 4. Avera, Di 36 Avista Corporation 1 . 49equity. "Regulatory Finance: Utilities Cost of Capital 2 noted the inherent difficulties of the DCF approach: 3 (C) aution and judgment are required in 4 interpreting the results of DCF models because of 5 (1) the questionable applicability of the DCF 6 model to utility stocks in certain market 7 environments, (2) the effect of declining 8 earnings and dividends on financial inputs to the 9 DCF model and biases caused by the effect of10 changes in risk and growth, and (3) the11 conceptual and practical difficulties associated 12 wi th the growth component of the DCF model. 50 13 The publication concluded,~If the cost of equity 14 estimation process is limited to one methodology, such as 15 DCF, it may severely bias the results. ,,51 16 17 18 Q. How did you apply the CAPM to estimate the cost of equity? A. Like the DCF model, the CAPM is an ex-ante, or 19 forward-looking model based on expectations of the future. 20 As a result, in order to produce a meaningful estimate of 21 investors' required rate of return, the CAPM is best 22 applied using estimates that reflect the expectations of 23 actual investors in the market, not with backward-looking, 24 historical data. 25 I applied the CAPM to the utility proxy group based on 26 a forward-looking estimate for investors' required rate of 49See, e.g., Bruner, R.F., Eades, K.M., Harris, R.S., and Higgins, R. C., "Best Practices in Estimating Cost of Capital: Survey and Synthesis," Financial Practice and Education (1998).50 Morin, Roger A., "Regulatory Finance: Utilities' Cost of Capital," Public Utilities Reports, Inc. (1994) at 238.51 Id. Avera, Di 37 Avista Corporation 1 return from common stocks.In addition, because it is 2 frequently referenced in regulatory proceedings, I also 3 applied the CAPM using risk premiums based on historical 4 realized rates of return published by Ibbotson Associates 5 (now Morningstar). Reference to historical data represents 6 one way to apply the CAPM, but these realized rates of 7 return reflect, at best, an indirect estimate of investors' 8 current requirements.As a result,forward-looking 9 applications of the CAPM that look directly at investors' 10 expectations in the capital markets are apt to provide a 11 more meaningful guide to investors' required rate of 12 return. 13 Q. What cost of equity was indicated by the CAPM 14 approach? 15 A. As shown on Schedule WEA-8, my forward-looking 16 application of the CAPM model indicated an ROE of 17 approximately 12.2 percent for the utility proxy group. 18 Applying the forward-looking CAPM approach to the firms in 19 the non-utility proxy group (Schedule WEA-9) implied a cost 20 of equity of 11.4 percent. 21 Application of the CAPM to the firms in the utility 22 and non-utility proxy groups using risk premiums based on 23 historical realized rates of return published by Ibbotson 24 Associates is presented on Schedules WEA-10 and WEA-11, 25 respectively.As shown there,this historical CAPM 26 approach implied a cost of equity of 10.7 percent for the Avera, Di 38 Avista Corporation 1 utility proxy group and 10.0 percent for the firms in the 2 non-utility proxy group. 3 Q. Wht other analyses did you conduct to estimate 4 the cost of equity? 5 A. As I noted earlier, I also evaluated the cost of 6 equi ty using the expected earnings method.Reference to 7 rates of return available from alternative investments of 8 comparable risk can provide an important benchmark in 9 assessing the return necessary to assure confidence in the 10 financial integrity of a firm and its ability to attract 11 capital.This expected earnings approach is consistent 12 wi th the economic underpinnings for a fair rate of return 13 established by the Supreme Court. Moreover, it avoids the 14 complexities and limitations of capital market methods and 15 instead focuses on the returns earned on book equity, which 16 are readily available to investors. 17 Q. What rates of return on equity are indicated for 18 utilities based on the expected earnings approach? 19 A. Value Line reports that its analysts anticipate 20 an average rate of return on common equity for the electric 21 utility industry of 11.5 percent over its forecast 22 horizon, 52 with natural gas distribution utilities expected 23 to earn an average rate of return on common equity of 11.5 52 The Value Line Investment Survey at 1776 (Feb. 8, 2008). Avera, Di 39 Avista Corporation 1 percent to 12.0 percent. 53 As shown on Schedule WEA- 12, 2 Value Line's projections for the utility proxy group 3 suggested an average ROE of 10.5 percent after eliminating 4 potential outliers. 54 Based on the results discussed above, 5 I concluded that the expected earnings approach implies a 6 fair rate of return on equity of 11.0 percent. 7 8 9 Q. Wht did you equi ty implied by your A. The cost of conclude analyses equity wi th respect to the cost for the proxy groups? estimates implied by of my 10 quantitative analyses are sumarized in Table 4, below:11 TABLE 412 SUMY OF QUANITATIVE RESULTS Method DCF CAPM Forward - looking Historical Expected Earnings Cost of Equity Estimates utility Non-utility Proxy Group Proxy Group 10.7%12.6% 12.2% 10.7% 11. 0% 11.4% 10.0% 13 Based on the results of my quantitative analyses, and 14 my assessment of the relative strengths and weaknesses 15 inherent in each method, I concluded that the cost of 16 equi ty is in the 10.7 percent to 12.2 percent range. 53 The Value Line Investment Survey 445 (Dec. 14, 2007).54 As highlighted on Schedule WEA-12, I eliminated two low-end estimates of 7.1 percent, as well as an extreme high-end outlier of24.4%.

In addition to presenting the conclusions of my 4 evaluation of a fair rate of return on equity range for 5 Avista,this section also discusses the relationship 6 between ROE and preservation of a utility's financial 7 integrity and the ability to attract capital under 8 reasonable terms on a sustainable basis. 9 A. implications for Financial integrity 10 Q. Why is it important to allow Avista an adequate 11 return on equity? 12 A. Given the importance of the utility industry to 13 the economy and society, it is essential to maintain 14 reliable and economical service to all consumers.While 15 Avista remains committed to provide reliable utility 16 service, a utility's ability to fulfill its mandate can be 17 compromised if it lacks the necessary financial wherewithal 18 or is unable to earn a return sufficient to attract 19 capital.Coupled with the ongoing potential for energy 20 market volatility,Avista's plans for infrastructure 21 investment and ongoing exposure to regulatory uncertainty 22 pose a numer of potential challenges that might require 23 the relatively swift commitment of significant capital 24 resources in order to maintain the high level of service 25 that customers have come to expect. Avera, Di 41 Avista Corporation 1 As documented earlier, the maj or rating agencies have 2 warned of exposure to uncertainties associated with 3 poli tical and regulatory developments, especially in view 4 of the pressures associated with large capital expenditure 5 programs and the potential for high and volatile commodity 6 costs in wholesale energy markets.Inves tors unders tand 7 just how swiftly unforeseen circumstances can lead to 8 deterioration in a utility's financial condition, and 9 stakeholders have discovered first hand how difficult and 10 complex it can be to remedy the situation after the fact. 11 While providing the infrastructure necessary to enhance the 12 power system and meet the energy needs of customers is 13 14 15 certainly desirable,it imposes additional financial responsibili ties on Avista.For a utility with an 16 increased reticence to supply additional capital during obligation provide reliable service,investors'to 17 times of crisis highlights the necessity of preserving the 18 flexibility necessary to overcome periods of adverse 19 20 21 22 23 24 25 These considerations heightencapi tal market conditions. the importance of allowing Avista an adequate return on the fair value of its investment. Q. What role does. regulation play in ensuring that Avista has access to capital under reasonable terms and on a sustainable basis? A. Considering investors' heightened awareness of 26 the risks associated with the utility industry and the Avera, Di 42 Avista Corporation 1 damage that results when a utility's financial flexibility 2 is compromised, supportive regulation remains crucial to 3 Avista's access to capital.Investors recognize that 4 regulation has its own risks,and that constructive 5 regulation is a key ingredient in supporting utility credit 6 ratings and financial integrity, particularly during times 7 of adverse conditions. S&P noted that: 8 9 10 11 12 13 14 Regulatory rulings have returned to center stage as a dominant factor in assessing companies' credit quality. These decisions will be critical for an industry that in many jurisdictions is nearing the end of extended transition periods and will be making significant capital investment in infrastructure during the next several years. 55 15 with respect to Avista specifically, the major bond 16 rating agencies have noted the near-term challenges posed 17 by upward pressure on costs and rising capital 18 expendi tures, while explicitly citing the potential that 19 adverse regulatory rulings could compromise the Company's 20 credi t standing. 56 Of particular concern to investors is 21 the impact of regulatory lag and cost-recovery on Avista' s 22 ability to earn its authorized ROE and maintain its 23 financial metrics, with Moody's noting an ongoing need for 55 Standard & Poor's Corporation, U Industry Report Card: U. S. Electric/Gas/Water," RatingsDirect (May 3,2005).56 See, e.g., Standard & Poor's Corporation, UAvista Corp.'s Corporate Credit Rating Raised One Notch To 'BBB-'," RatingsDirect (Feb 7, 2008); Moody's Investors Service, "Credit Opinion: Avista Corp.," Global Credit Research (Dec. 21, 2007). Avera, Di 43 Avista Corporation 1 supportive regulation in light of a significant capital 2 investment program. 57 Moody's concluded: 3 Continuation of supportive treatment in future 4 PGA and general rate cases would be particularly 5 important in helping Avista continue to make 6 progress towards consistently earning at the7 utility division's allowed level of return on its 8 inves tmen t . 58 9 S&P concluded that Avista' s credit outlook could be revised 10 to "negative" if the Company's financial profile is 11 weakened due to an inability to obtain timely rate relief. 59 12 Moreover, the negative impact of declining credit 13 quality on a utility's capital costs and financial 14 flexibility becomes more pronounced as debt ratings move 15 down the scale from investment to non-investment grade. In 16 light of Avista' s present ratings, an inadequate rate of 17 return imposed in this proceeding would further pressure 18 the Company's financial flexibility and credit standing. 19 20 21 22 Q. highlight financial Do the potential exposures the need for ongoing support strength and ability to attract Most definitely.

Avera, Di 44 Avista Corporation 1 which its customers have become accustomed.Avista faces 2 the potential for fluctuating stream flows and significant 3 volatili ty in wholesale fuel and energy markets.S&P 4 concluded that Avista' s ~key utility risk going forward is 5 its exposure to high-cost replacement power, particularly 6 in low water years. ,,60 Given utili ties' lack of control 7 over the timing of such events, the Company must have the 8 wherewi thal to meet these challenges even when capital and 9 energy market conditions are unfavorable. 10 For Avista, these concerns are magnified by the fact 11 that its credit standing remains relatively weak.While 12 the Company's efforts to regain an investment grade credit 13 rating have been successful, Avista' s financial metrics 14 remain pressured.As Mr. Malquist confirms in his 15 testimony, regulatory support will be a key driver in 16 securing additional progress towards restoring the 17 Company's financial health. Further strengthening Avista's 18 financial integrity is imperative to ensure that the 19 Company has the capability to maintain an investment grade 20 rating while confronting potential challenges. 60 Standard & Poor's Corporation, "Avista Corp.'s Corporate Credit Rating Raised One Notch To 'BBB-'," RatingsDirect (Feb. 7, 2008). Avera, Di 45 Avista Corporation 1 Q. Do customers benefit by enhncing the utility's 2 financial flexibility? 3 A. Yes. While providing an ROE that is sufficient 4 to maintain Avista's ability to attract capital, even in 5 times of financial and market stress, is consistent with 6 the economic requirements embodied in the Supreme Court' s 7 Hope and Bluefield decisions, ¡t is also in customers' best 8 interests.Ultimately, it is customers and the service 9 area economy that enjoy the benefits that come from 10 ensuring that the utility has the financial wherewithal to 11 take whatever actions are required to ensure reliable 12 service.By the same token, customers also bear a 13 significant burden when the ability of the utility to 14 attract necessary capital is impaired and service quality 15 is compromised. 16 B. Flotation Costs 17 Q. Wht other considerations are relevant in setting 18 the return on equity for a utility? 19 A. The common equity used to finance the investment 20 in utility assets is provided from either the sale of stock 21 in the capi tal markets or from retained earnings not paid 22 out as dividends.When equity is raised through the sale 23 of common stock, there are costs associated with ~floating" 24 the new equity securities.These flotation costs include 25 services such as legal, accounting, and printing, as well 26 as the fees and discounts paid to compensate brokers for Avera, Di 46 Avista Corporation 1 selling the stock to the public. Also, some argue that the 2 "market pressure" from the additional supply of common 3 stock and other market factors may further reduce the 4 amount of funds a utility nets when it issues common 5 equity. 6 Q.Is there an established mechanism for a utility 7 to recognize equity issuance costs? 8 A. No. While debt flotation costs are recorded on 9 the books of the utility, amortized over the life of the 10 issue, and thus increase the effective cost of debt 11 capital, there is no similar accounting treatment to ensure 12 that equity flotation costs are recorded and ultimately 13 recognized. Alternatively, no rate of return is authorized 14 on flotation costs necessarily incurred to obtain a portion 15 of the equity capital used to finance plant.In other 16 words, equity flotation costs are not included in a 17 utility's rate base because neither that portion of the 18 gross proceeds from the sale of common stock used to pay 19 flotation costs is available to invest in plant and 20 equipment, nor are flotation costs capitalized as an 21 intangible asset.Unless some provision is made to 22 recognize these issuance costs,a utility's revenue 23 requirements will not fully reflect all of the costs 24 incurred for the use of investors' funds. Because there is 25 no accounting convention to accumulate the flotation costs 26 associated with equity issues, they must be accounted for Avera, Di 47 Avista Corporation 10 11 1 indirectly, with an upward adjustment to the cost of equity 2 being the most logical mechanism. 3 4 5 Q. What is the magnitude of the adjustment to the "bare bones" cost of equity to account for issuance costs? A. There are any numer of ways in which a flotation 6 cost adjustment can be calculated, and the adjustment can 7 range from just a few basis points to more than a full 8 One of the most common methods used to accountpercent. 9 for flotation costs in regulatory proceedings is to apply an average flotation-cost percentage to a utility's di vidend yield.Based on a review of the finance 12 li terature, Regulatory Finance: Utili ties' Cost of Capi tal 13 14 15 16 17 18 concluded: allowance requires anthe return on equi ty of depending on the size The flotation costestimated adjustment to approximately 5% to 10%, and risk of the issue. 61 Al ternati vely,a study of data from Morgan Stanley 19 regarding issuance costs associated with utility common 20 stock issuances flotation costsuggestsanaverage 21 percentage of 3.6%.62 Applying these expense percentages to 22 a representative dividend yield for a utility of 4.0 61 Roger A. Morin, Regulatory Finance: Utilities' Cost of Capital, 1994, at 166.62 Application of Yankee Gas Services Company for a Rate Increase, DPUC Docket No. 04-06-01, Direct Testimony of George J. Eckenroth (Jul. 2, 2004) at Exhibit GJE-11.1. Updating the results presented by Mr. Eckenroth through April 2005 also resulted in an average flotation cost percentage of 3.6%. Avera, Di 48 Avista Corporation i percent implies a flotation cost adjustment on the order of 2 14 to 40 basis points. 3 4 5 Q. Has flotation costs A. Yes. the i PUC Staff previously considered in estimating a fair ROE? For example, in Case No. IPC-E-07-8, IPUC 6 Staff witness Terri Carlock noted that she had adjusted her 7 DCF analysis to incorporate an allowance for flotation 8 costS.63 While issuance costs are a legitimate 9 consideration in setting the return on equity for a 10 utility, a specific adjustment for flotation costs was not 11 included in defining my recommended ROE range. 12 c. Return on EQUity Recommendation 13 Q. What then is your conclusion as to a fair rate of 14 return on equity range for Avista? 15 A. As explained above,. based on the capital market 16 oriented analyses for the utility and non-utility proxy 17 groups described in my testim~ny, I concluded that the fair 18 rate of return on equity range was 10.7 percent to 12.2 19 percent.Considering capital market expectations, the 20 potential exposures faced by Avista, and the economic 21 requirements necessary to maintain financial integrity and 22 support additional capital investment even under adverse 23 circumstances, it is my opinion that this represents a fair 24 and reasonable ROE range for Avista. 63 Case No. IPC-E-07-8, Direct Testimony of Terri Carlock at 10 (Dec. 10, 2007). Avera, Di 49 Avista Corporation 1 Q. Based on the results of your evaluation, what is 2 your opinion regarding the reasonaleness of the ROE 3 requested by Avista in this case? 4 A. My evaluation indicates that Avista' s requested 5 ROE of 10.8 percent represents a conservative estimate of 6 investors' required rate of return.Given the fact that 7 the Company's requested ROE falls barely above the lower 8 bound of my recommended range, it should be viewed as an 9 absolute floor in establishing rates for Avista.This 10 conclusion is reinforced by the need to buttress the 11 Company's credit standing, which remains relatively weak, 12 as well as the pressures of funding significant capital 13 expendi tures and meeting increased operating risks, 14 including those associated with Avista' s reliance on 15 hydroelectric generation and wholesale energy markets. The 16 reasonableness of a minimum 10.8 percent ROE for Avista is 17 also supported by the Company's relatively greater risks as 18 compared with the proxy groups, the higher uncertainties 19 associated with Avista' s relatively small size, and the 20 fact that my recommended ROE range does not consider 21 flotation costs. 22 23 24 Q.

Schedule WEA-2 presents capital market estimates 3 of the cost of equity. First, I examine the concept of the 4 cost of equity, along with the risk-return tradeoff 5 principle fundamental to capital markets. Next, I describe 6 DCF, CAPM, and expected earnings analyses conducted to 7 estimate the cost of equity for reference groups of S comparable risk firms. 9 10 11 12 A. Overview Q. What role does the rate of return on commn equity play in a utility's rates? A. The return on common equity is the cost of inducing and retaining investment in the utility's physical 13 plant and assets.This investment is necessary to finance 14 the asset base needed to provide utility service. 15 Investors will commit money to a particular investment only 16 if they expect it to produce a return commensurate with 17 those from other investments with comparable risks. lS Moreover, the return on common equity is integral in 19 achieving the sound regulatory objectives of rates that are 20 sufficient to: 1) fairly compensate capital investment in 21 the utility, 2) enable the utility to offer a return 22 adequate to attract new capital on reasonable terms, and 3) Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 1 of 27 1 maintain the utility's financial integrity. Meeting these 2 obj ectives allows the utility to fulfill its obligation to 3 provide reliable service while meeting the needs of 4 customers through necessary system expansion. 5 Q. What fundamntal economic principle underlies any 6 evaluation of investors' required return on equity? 7 A. The fundamental economic principle underlying the S cost of equity concept is the notion that investors are 9 risk averse. The required rate of return for a particular 10 asset at any point in time is a function of: 1) the yield 11 on risk-free assets, and 2) its relative risk, with 12 investors demanding correspondingly larger risk premiums 13 for assets bearing greater risk. Given this risk-return 14 tradeoff, the required rate of return (k) from an asset (i) 15 can be generally expressed as: 16 ki = Rf + RPi 17 lS 19 where:Rf = Risk-free rate of return; and RPi = Risk premium required to holdrisky asset i. 20 Thus, the required rate of return for a particular asset at 21 any point in time is a function of: 1) the yield on risk- 22 free assets, and 2) its relative risk, with investors 23 demanding correspondingly larger risk premiums for assets 24 bearing greater risk. 25 Because common shareholders have the lowest priority 26 claim on a firm's cash flows, they receive only the Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 2 of 27 1 residual that remains after all other claimants (employees, 2 suppliers, governments, lenders) have been paid. As a 3 result, the rate of return that investors require from a 4 utility's common stock, the most junior and riskiest of its 5 securi ties, is considerably higher than the yield on the 6 utili ty' s long-term debt. 7 Q. Is the cost of equity observable in the capital S markets? 9 A. No. Unlike debt capital, there is no 10 contractually guaranteed return on common equity capital 11 since shareholders are the residual owners of the utility. 12 Because it is unobservable, the cost of equity for a 13 particular utility must be estimated by analyzing 14 information about capital market conditions generally, 15 assessing the relative risks of the company specifically, 16 and employing various quantitative methods that focus on 17 investors' current required rates of return. These various lS quantitative methods typically attempt to infer investors' 19 required rates of return from stock prices, interest rates, 20 or other capital market data. 21 22 23 Q. equity? A. A. Discounted Cash Flow Analvses How are DCF models used to estimate the cost of DCF models attempt to replicate the market 24 valuation process that sets the price investors are willing 25 to pay for a share of a company's stock. The model rests Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 3 of 27 1 on the assumption that investors evaluate the risks and 2 expected rates of return from all securities in the capital 3 markets. Given these expectations, the price of each stock 4 is adjusted by the market until investors are adequately 5 compensated for the risks they bear. Therefore, we can 6 look to the market to determine what investors believe a 7 share of common stock is worth. By estimating the cash S flows investors expect to receive from the stock in the way 9 of future dividends and capital gains, we can calculate 10 their required rate of return. In other words, the cash 11 flows that investors expect from a stock are estimated, and 12 given its current market price, we can ~back-into" the 13 discount rate, or cost of equity, that investors implicitly 14 used in bidding the stock to that price. 15 16 17 Q. models? A. Wht market valuation process underlies DCF DCF models assume that the price of a share of lS common stock is equal to the present value of the expected 19 cash flows (i. e., future dividends and stock price) that 20 will be received while holding the stock, discounted at 21 investors' required rate of return. That is, the cost of 22 equi ty is the discount rate that equates the current price 23 of a share of stock with the present value of all expected 24 cash flows from the stock. Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 4 of 27 1 Q. What form of the DCF model is customarily used to 2 estimate the cost of equity in rate cases? 3 A. Rather than developing annual estimates of cash 4 flows into perpetuity, the DCF model can be simplified to a 5 "constant growth" f~rm: 1 6 p _ 010- ke-g 7 S 9 10 11 12 where: Po = Current price per share; D1 = Expected dividend per share in the coming year; ke = Cost of equity; g = Investors' long-term growthexpectations. 13 The cost of equity (Ke) can be isolated by rearranging 14 terms: 15 ok =-1+ge p o 16 This constant growth form of the DCF model recognizes that 17 the rate of return to stockholders consists of two parts: lS 1) dividend yield (D1/PO)' and 2) growth (g).In other 19 words, investors expect to receive a portion of their total 20 return in the form of current dividends and the remainder 21 through price appreciation. 1 The constant growth DCF model is dependent on a numer of strict assumptions, which in practice are never strictly met. These include a constant growth rate for both dividends and earnings; a stable dividend payout ratio; the discount rate exceeds the growth rate; a constant growth rate for book value and price; a constant earned rate of return on book value; no sales of stock at a price above or below book value; a constant price-earnings ratio; a constant discount rate(i. e., no changes in risk or interest rate levels and a flat yield curye); and all of the above extend to infinity. Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 5 of 27 1 2 3 Q. How did you define the utility proxy group you used to implement the DCF model? A. As discussed in my testimony, my utility proxy 4 group was composed of those dividend-paying companies 5 included by Value Line in its Electric Utilities Industry 6 groups with: (1) S&P corporate credit ratings between ~BBB- 7 "and ~BBB+," (2) a Value Line Safety Rank of ~2" or ~3", Sand (3) a Value Line Financial Strength Rating of ~B+" to 9 ~B++", and (4) published growth estimates from IBES, Value 10 Line, Reuters, and Zacks. I excluded two companies that 11 otherwise would have been in the proxy group (Energy East 12 Corporation and Puget Energy, Inc.) because they are in the 13 process of being acquired. 14 Q. Do these criteria provide objective evidence that 15 investors would view the fir.s in the utility proxy group 16 as risk-comparable to Avista? 17 A. Yes. Credit ratings are assigned by independent lS rating agencies to provide investors with a broad 19 assessment of the creditworthiness of a firm. Because the 20 rating agencies' evaluation includes virtually all of the 21 factors normally considered important in assessing a firm's 22 relative credit standing, corporate credit ratings provide 23 a broad measure of overall investment risk that is readily 24 available to investors. Widely cited in the investment 25 community and referenced by investors as an objective 26 measure of risk, credit ratings are also frequently used as Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 6 of 27 1 a primary risk indicator in establishing proxy groups to 2 estimate the cost of equity. 3 Apart from the broad assessment of investment risk 4 provided by credit ratings, other quality rankings 5 published by investment advisory services also provide 6 relative assessments of risk that are considered by 7 investors in forming their expectations. Given that Value S Line is perhaps the most widely available source of 9 investment advisory information, its Safety Rank and 10 Financial Strength Rating provide useful guidance regarding 11 the risk perceptions of investors. 12 The Safety Rank is Value Line's primary risk indicator 13 and ranges from ~1" (Safest) to ~S" (Riskiest). This 14 overall risk measure is intended to capture the total risk 15 of a stock, and incorporates elements of stock price 16 stability and financial strength. The Financial Strength 17 Rating is designed as a guide to overall financial strength lS and creditworthiness, with the key inputs including 19 financial leverage, business volatility measures, and 20 company size. Value Line's Financial Strength Ratings 21 range from ~A++" (strongest) down to "C" (weakest) in nine 22 steps. 23 As discussed earlier, Avista is rated "BBB-" by S&P, 24 which indicates slightly greater risk than the ~BBB" 25 average rating for the firms in the utility proxy group. 26 Meanwhile, Value Line has assigned Avista a Safety Rank of Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 7 of 27 9 10 1 ~3" and a Financial Strength Rating of ~B+" versus averages 2 of "3" and ~B++", respectively for the utility proxy group. 3 Based on my screening criteria, which reflect objective, 4 published indicators that incorporate consideration of a 5 broad spectrum of risks, including financial and business 6 position, relative size, and exposure to company specific 7 factors, investors are likely to regard this group as S having risks and prospects generally comparable to Avista. Q. A. What steps are required to apply the DCF model? The first step in implementing the constant 11 growth DCF model is to determine the expected dividend 12 yield (D1/Po) for the firm in question. This is usually 13 14 15 16 17 lS 19 20 21 22 23 calculated based on an estimate of dividends to be paid in the coming year divided by the current price of the stock. The second, and more controversial, step is to estimate investors i long-term growth expectations (g) for the firm. The final step is to sum the firm's dividend yield and estimated growth rate to arrive at an estimate of its cost of equity. Q. How was the dividend yield for the utility proxy group det er.i ned ? A. Estimates of dividends to be paid by each of these utili ties over the next twelve months, obtained from 24 Value Line, served as D1. This annual dividend was then 25 divided by the corresponding stock price for each utility 26 to arrive at the expected dividend yield. The expected Exhibi t No. 3 Case -Nos AVU-E-OS-01 & AVU-G-08-01 W. Avera, Avista Schedule WEA-2, p. S of 27 1 dividends, stock prices, and resul ting dividend yields for 2 the firms in the utility proxy group are presented on 3 Schedule WEA-4. As shown there, dividend yields for the 4 twenty firms in the utility proxy group ranged from 2.4 5 percent to 6.0 percent. 6 7 S Q. What is the next step in applying the constant growth DCF model? A. The next step is to evaluate long-term growth 9 expectations, or "g", for the firm in question. In 1 0 cons tan t growth DCF theory, earnings , dividends, book 11 value, and market price are all assumed to grow in 12 lockstep, and the growth horizon of the DCF model is 13 infinite. But implementation of the DCF model is more than 14 just a theoretical exercise; it is an attempt to replicate 15 the mechanism investors used to arrive at observable stock 16 prices. A wide variety of techniques can be used to derive 1 7 growth rates, but the only ~ g" that matters in applying the lS DCF model is the value that investors expect. 19 Q. Are historical growth rates likely to be 20 representative of investors' expectations for utilities? 21 A. No. If past trends in earnings, dividends, and 22 book value are to be representative of investors' 23 expectations for the future, then the historical conditions 24 giving rise to these growth rates should be expected to 25 continue. That is clearly not the case for utili ties, 26 where structural and industry changes have led to declining Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 9 of 27 1 dividends, earnings pressure, and, in many cases, 2 significant write-offs. While these conditions serve to 3 depress historical growth measures, they are not 4 representative of long-term expectations for the utility 5 industry. Moreover, to the extent historical trends for 6 utili ties are meaningful, they are also captured in 7 proj ected growth rates, since securities analysts also S routinely examine and assess the impact and continued 9 relevance (if any) of historical trends. 10 Q. What are investors most likely to consider in 11 developing their long-term growth expectations? 12 A. While the DCF model is technically concerned with 13 growth in dividend cash flows, implementation of this DCF 14 model is solely concerned with replicating the forward- 15 looking evaluation of real-world investors. In the case of 16 electric utilities, dividend growth rates are not likely to 17 provide a meaningful guide to investors i current growth lS expectations. This is because utilities have significantly 19 altered their dividend policies in response to more 20 accentuated business risks in the industry. 2 As a result 21 of this trend towards a more conservative payout ratio, 22 dividend growth in the utility industry has remained 23 largely stagnant as utilities conserve financial resources 24 to provide a hedge against heightened uncertainties. 2 For example, the payout ratio for electric utilities fell from approximately 80% historically to on the order of 60%.

Avera, Avis ta Schedule WEA-2, p. 10 of 27 1 As payout ratios for firms in the utility industry 2 trended downward, investors' focus has increasingly shifted 3 from dividends to earnings as a measure of long-term 4 growth. Future trends in earnings, which provide the 5 source for future dividends and ultimately support share 6 prices, playa pivotal role in determining investors' long- 7 term growth expectations. The importance of earnings in 8 evaluating investors' expectations and requirements is well 9 accepted in the investment community. As noted in Finding 10 Reali ty in Reported Earnings published by the Association 11 for Investment Management and Research: 12 (E) arnings, presumably, are the basis for the13 investment benefits that we all seek. ~Healthy14 earnings equal healthy investment benefits" seems15 a logical equation, but earnings are also a16 scorecard by which we compare companies, a filter 17 through which we assess management, and a crystal18 ball in which we try to foretell future19 performance. 3 20 Value Line's near-term projections and its Timeliness 21 Rank, which is the principal investment rating assigned to 22 each individual stock, are also based primarily on various 23 quantitative analyses of earnings. As Value Line 24 explained: 25 The future earnings rank accounts for 65% in the26 determination of relative price change in the27 future; the other two variables (current earnings28 rank and current price rank) explain 35%.4 3 Association for Investment Manag~ent and Research, uFinding Reality in Reported Earnings: An Overview", p. 1 (Dec. 4, 1996).4 The Value Line Investment Survey, Subscriber i s Guide, p. 53. Exhibi t No. 3 Case Nos AVU-E-08-01 & AVU-G-08-01 W. Avera, Avista Schedule WEA-2, p. 11 of 27 1 The fact that investment advisory services, such as Value 2 Line, Thompson, and Reuters, focus on growth in earnings 3 indicates that the investment community regards this as a 4 superior indicator of future long-term growth. Indeed, ~A 5 Study of Financial Analysts: Practice and Theory," 6 published in the Financial Analysts Journal, reported the 7 resul ts of a survey conducted to determine what analytical S techniques investment analysts actually use. 5 Respondents 9 were asked to rank the relative importance of earnings, 10 dividends, cash flow, and book value in analyzing 11 securities. Of the 297 analysts that responded, only 3 12 ranked dividends first while 276 ranked it last. The 13 article concluded: 14 Earnings and cash flow are considered far more15 important than book value and dividends. 6 16 More recently, the Financial Analysts Journal reported 17 the results of a study of the relationship between lS valuations based on alternative multiples and actual market 19 prices, which concluded, ~ In all cases studied, earnings 20 dominated operating cash flows and dividends.

What are security analysts currently projecting in the way of growth for the firms in the utility proxy group? A. The IBES earnings growth projections for each of 5 the firms in the utility proxy group reported by Thomson 6 Financial are displayed on Schedule WEA-4. Also presented 7 are the earnings per share (~EPS") growth projections S reported by Value Line, Reuters, and Zacks. Q. How else are investors' expectations of future long-term growth prospects often estimated for use in the constant growth DCF model? A. Based on the assumptions underlying constant growth theory, conventional applications of the constant growth DCF model often examine the relationship between retained earnings and earned rates of return as an indication of the sustainable growth investors might expect 17 from the reinvestment of earnings within a firm. The lS sustainable growth rate is calculated by the formula, g = 19 br+sv, where ~b" is the expected retention ratio, ~r" is 20 the expected earned return on equity, ~s" is the percent of 21 common equity expected to be issued annually as new common 22 stock, and "v" is the equity accretion rate. 23 24 Q. A. What is the purpose of the "sv" term? Under DCF theory, the ~sv" factor is a component 25 of the growth rate designed to capture the impact of 26 issuing new common stock at a price above, or below, book 27 value. When a company's stock price is greater than its Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 13 of 27 1 book value per share, the per-share contribution in excess 2 of book value associated with new stock issues will accrue 3 to the current shareholders. This increase to the book 4 value of existing shareholders leads to higher expected 5 earnings and dividends, with the ~sv" factor incorporating 6 this additional growth component. 7 Q. How did you apply the earnings retention method S for the proxy group of utilities? 9 A. The sustainable, . ~br+sv" growth rates for each 10 firm in the proxy group are sumarized on Schedule WEA-4, 11 with the underlying details being presented on 12 Schedule WEA-S. For each firm, the expected retention 13 ratio (b) was calculated based on Value Line's projected 14 dividends and earnings per share. Likewise, each firm's 15 expected earned rate of return (r) was computed by dividing 16 projected earnings per share by projected net book value. 17 Because Value Line reports end-of-year book values, an lS adjustment was incorporated to compute an average rate of 19 return over the year, consistent with the theory underlying 20 this approach to estimating investors' growth expectations. 21 Meanwhile, the percent of common equity expected to be 22 issued annually as new common stock (s) was equal to the 23 product of the projected market-to-book ratio and growth in 24 common shares outstanding, while the equity accretion rate 25 (v) was computed as 1 minus the inverse of the projected 26 market-to-book ratio.

What cost of equity estimates were implied for 2 the utility proxy group using the DCF model? 3 A. After combining the dividend yields and 4 respective growth projections for each utility, the 5 resulting cost of equity estimates are shown on 6 Schedule WEA-4. Q. In evaluating the results of the constant growth DCF model, is it appropriate to eliminate cost of equity estimates that fail to meet threshold tests of economic logic? A. Yes. It is a basic economic principle that investors can be induced to hold more risky assets only if they expect to earn a return to compensate them for their 14 risk bearing. As a result, the rate of return that 15 investors require from a utility's common stock, the most 16 junior and riskiest of its securities, must be considerably 17 higher than the yield offered by senior, long-term debt. lS Consistent with this principle, the DCF range for the proxy 19 group of electric utilities must be adjusted to eliminate 20 cost of equity estimates that fail fundamental tests of 21 economic logic. 22 23 Q. A. Have similar tests been applied by regulators? Yes. The FERC has noted that adjustments are 24 justified where applications of the DCF approach produce 25 illogical results. FERC evaluates DCF results against 26 observable yields on long-term public utility debt and has 27 recognized that it is appropriate to eliminate cost of Exhibi t No. 3 Case Nos AVU-E-08-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 15 of 27 1 equity estimates that do not sufficiently exceed this 2 threshold. In a 2002 opinion establishing its current 3 precedent for determining ROEs for electric utili ties, for 4 example, FERC concluded: 5 An adjustment to this data is appropriate in the 6 case of PG&E's low-end return of 8.42 percent, 7 which is comparable to the average Moody's "A"S grade public utility bond yield of S. 06 percent, 9 for October 1999. Because investors cannot be10 expected to purchase stock if debt, which has11 less risk than stock, yields essentially the same12 return, this low-end return cannot be considered13 reliable in this case. 8 14 More recently, in its October 2006 decision in Kern River 15 Gas Transmission Company, FERC noted that: 16 (T)he 7.31 and 7.32 percent costs of equity for 17 El Paso and Williams found by the ALJ are only lS 110 and 122 basis points above that average yield19 for public utility debt. 9 20 FERC upheld the opinion of Staff and the Administrative Law 21 Judge that cost of equity estimates for these two proxy 22 group companies ~were too low to be credible. ,,10 23 Q. What does this test of logic imply with respect 24 to the DCF results for the utility proxy group? 25 A. The average bond rating associated with the firms 26 in the utility proxy group is triple-B, with Moody's 27 monthly yields on triple-B bonds averaging approximately 2S 6.4 percent in January 200S. 11 As highlighted on 29 Schedule WEA-4, six of the individual equity estimates for 8 Southern California Edison Company, 92 FERC î 61,070 (2000) at p. 22. 9 Kern River Gas Transmission Company, Opinion No. 486, 117 FERC î 61,077 at P 140 & n. 227 (2006).10 Id. 11 Moody's Investors Service, Credit Perspectives (Feb. 11, 2008).

Avera, Avista Schedule WEA-2, p. 16 of 27 1 the firms in the utility proxy group exceeded this 2 threshold by 120 basis points or less. 12 In light of the 3 risk-return tradeoff principle and the test applied in Kern 4 River Gas Transmission Company, it is inconceivable that 5 investors are not requiring a substantially higher rate of 6 return for holding common stock, which is the riskiest of a 7 utility's securities. As a result, these values provide S little guidance as to the returns investors require from 9 the common stock of an electric utility. 10 Q. Do you also recommend excluding cost of equity 11 estimates at the high end of the range of DCF results? 12 A. Yes. As highlighted on Schedule WEA-4, I also 13 eliminated cost of equity estimates at the upper end of the 14 range of DCF results.Compared with the balance of the 15 remaining estimates, these values are extreme outliers and 16 should also be excluded in evaluating the results of the 17 DCF model for the utility proxy group. This is also lS consistent with the approach and threshold adopted by FERC, 19 which established that a 17.7 percent DCF estimate for an 20 electric utility was ~an extreme outlier" and should be 21 disregarded.

As shown on Schedule WEA-4 and sumarized in 4 Table 1, below, after eliminating illogical low- and high- 5 end values, application of the constant growth DCF model 6 resulted in the following cost of equity estimates:7 TABLE 1S DCF RESULTS - UTILITY PROXY GROUP Growth Rate IBES Value Line Reuters Zacksbr+sv Average Cost of Equity 11. 3% 10.4% 10.6% 10.9% 9.2% 9 Q.

Under the regulatory standards established by Hope and Bluefield, the salient criteria in establishing a meaningful benchmark to evaluate a fair rate of return is relative risk, not the particular business activity or 22 degree of regulation.

Avera, Avista Schedule WEA-2, p. lS of 27 1 other investment opportunities of comparable risk. with 2 regulation taking the place of competitive market forces, 3 required returns for utili ties should be in line with those 4 of non-utility firms of comparable risk operating under the 5 constraints of free competition. Consistent with this 6 accepted regulatory standard, I also applied the DCF model 7 to a reference group of comparable risk companies in the S non-utility sector of the economy. 9 Q. What criteria did you apply to evaluate 10 investors' risk perceptions? 11 A. As discussed in my testimony, my assessment of 12 comparable risk relied on three objective benchmarks for 13 the risks associated with common stocks -- Value Line's 14 Safety Rank, Financial Strength rating, and beta. My lS comparable risk proxy group was composed of those U.S. companies followed by value Line that 1)pay common dividends,2 )have a Safety Rank of ~ 1 It ,2 )have a Financial Strength Rating of ~AIt or above,and 3)have beta values of 0.90 or less,14 and (4 )have published data from 15 16 17 19 20 IBES, Value Line, Reuters, and Zacks. Cons is ten t wi th the 21 development of my utility proxy group, I also eliminated 22 firms with below-investment grade credit ratings. 14 This threshold corresponds to the average beta of 0.89 for the utility proxy group discussed earlier.

As shown on Schedule WEA-6, I applied the DCF 4 model to the non-utility proxy group in exactly the same 5 manner described earlier for the utility proxy group. 15 As 6 sumarized in Table 2, below, after eliminating illogical 7 low- and high-end values, application of the constant S growth DCF model resulted in the following cost of equity 9 estimates: 10 TABLE 2 11 DCF RESULTS - NON-UTILITY PROXY GROUP Growth RateI/B/E/S Value LineReuters Zacksbr+sv Average Cost of EQUity 12.9% 12.2% 12.5% 12.7% 13.0% 12 Taken together, I concluded that the constant growth DCF 13 results for the non-utility proxy group implied a cost of 14 equity of 12.6 percent. 15 16 Q A. B. Capi tal Asset Pricing Model Please describe the CAPM. The CAPM is a theory of market equilibrium that 17 measures risk using the beta coefficient. The CAPM assumes lS that investors are fully diversified, so the relevant risk 19 of an individual asset (e.g., common stock) is its 20 volatility relative to the market as a whole. Beta 15 Schedule WEA-7 contains the details underlying the calculation of the br+sv growth rates for the non-utility proxy group. Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 20 of 27 S 9 10 11 12 13 14 15 16 17 lS 19 20 21 22 23 24 1 reflects the tendency of a stock's price to follow changes 2 in the market. A stock that tends to respond relatively 3 less to market movements has a beta less than 1.00, while 4 stocks that tend to move more than the market have betas 5 greater than 1.00. The CAPM is mathematically expressed 6 as: 7 Rj = Rf + e j (Rm - Rf) where: Rj = required rate of return for stock j; Rf = risk-free rate; R. = expected return on the market portfolio; and,ej = beta, or systematic risk, for stock j. Like the DCF model, the CAPM is an ex-ante, or forward-looking model based on expectations of the future. As a result, in order to produce a meaningful estimate of investors' required rate of return, the CAPM must be applied using estimates that reflect the expectations of actual investors in the market, not with backward-looking, historical data. Q. How did you apply the CAPM to estimate the cost of equity? A. Application of the CAPM to the utility proxy group based on a forward-looking estimate for investors' 25 Schedule WEA-S. In order to capture the expectations of required rate of return from common stocks is presented on 26 today's investors in current capital markets, the expected Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 21 of 27 1 market rate of return was estimated by conducting a DCF 2 analysis on the dividend paying firms in the S&P 500. 3 The dividend yield for each firm was obtained from 4 Value Line, with the growth rate being equal to the average 5 of the earnings growth proj ections for each firm compiled 6 by IBES and Value Line, with each firml s dividend yield and 7 growth rate being weighted by its proportionate share of S total market value. Based on the weighted average of the 9 proj ections for the 354 individual firms, current estimates 10 imply an average growth rate over the next five years of 11 11.0 percent. Combining this average growth rate with a 12 dividend yield of 2.2 percent results in a current cost of 13 equity estimate for the market as a whole of approximately 14 13.2 percent. Subtracting a 4.4 percent risk-free rate 15 based on the average yield on 20-year Treasury bonds for 16 January 200S produced a market equity risk premium of S. S 17 percent. Multiplying this risk premium by the average lS Value Line beta of O. S9 for the utility proxy group, and 19 then adding the resulting 7. S percent risk premium to the 20 average long-term Treasury bond yield, indicated an ROE of 21 approximately 12.2 percent. Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 22 of 27 1 Q. What cost of equity was indicated for the non- 2 utility proxy group based on this forward-looking 3 application of the CAPM? 4 A. As shown on Schedule WEA-9, applying the forward- 5 looking CAPM approach to the firms in the non-utility proxy 6 group implied a cost of equity of 11.4 percent. 7 Q. What other CAPM analyses did you conduct to S estimate the cost of equity? 9 A. I also applied the CAPM using risk premiums based 10 on historical realized rates of return. This approach to 11 estimating investors' equity risk premiums is premised on 12 the notion that past experience heavily conditions future 13 expectations. The essential assumption of the historical 14 risk premium when used in the CAPM approach is that, while 15 historical returns do not predict the future, investors 16 form expectations of future stock returns based on 17 observable debt yields and the historical experience of lS returns from common stock investments relative to debt 19 investments. 20 While reference to historical data represents one way 21 to apply the CAPM, these realized rates of return reflect, 22 at best, an indirect estimate of investors' current 23 requirements. The cost of capital is a forward-looking, or 24 expectational concept that is focused on the perceptions of 25 today's capital market investors. Past investment returns 26 are frequently referenced and may provide a useful 27 benchmark, but the only factors that actually determine the Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avis ta Schedule WEA-2, p. 23 of 27 1 current required rate of return are investors' expectations 2 for the future. As a result, forward-looking applications 3 of the CAPM that look directly at investors' expectations 4 in the capi tal markets are apt to provide a more meaningful 5 guide to investors' required rate of return. 6 Q. What CAPM cost of equity is produced based on 7 historical realized rates of return for stocks and long- S term governent bonds? 9 A. I applied the CAPM using data published by 10 Ibbotson Associates, which is perhaps the most exhaustive 11 and widely referenced annual study of realized rates of 12 return. Application of the CAPM based on historical 13 realized rates of return is presented in Schedule WEA-10. 14 In their 2007 Yearbook, Valuation Edition, Ibbotson 15 Associates reported that, over the period from 1926 through 16 2006, the arithmetic mean realized rate of return on the 17 S&P 500 exceeded that on long-term government bonds by 7.1 lS percent. 16 Multiplying this historical market risk 19 premium by the average Value Line beta of O. S9 20 produced an equity risk premium of 6.3 percent for the 21 utility proxy group. As shown on Schedule WEA-10, 22 adding this equity risk premium to the January 200S 23 average yield on 20-year Treasury bonds of 4.4 percent 24 resulted in an implied cost of equity of 10.7 percent. 16 Ibbotson Associates computes the equity risk premium by subtracting the income return (not the total return) on long-term Treasury bonds from the return on common stocks.

As shown on Schedule WEA-11, applying the Q. utility A. 4 historical CAPM approach to the firms in the non-utility 5 proxy group implied a cost of equity of 10.0 percent. C. Exected Earnings Method 6 Q. What other analyses did you conduct to estimate 7 the cost of equity? S A. As I noted earlier, I also evaluated the ROE 9 using the expected earnings method. Reference to rates of return available from alternative investments of comparable risk can provide an important benchmark in assessing the return necessary to assure confidence in the financial integrity of a firm and its ability to attract capital. This expected earnings approach is consistent with the economic underpinnings for a fair rate of return established by the Supreme Court in Hope and Bluefield. Moreover, it avoids the complexities and limitations of capi tal market methods and instead focuses on expected earned returns on book equi ty, which are more readily available to investors. Q. What rates of return are indicated for utili ties based on this approach? A. with respect to expectations for electric utilities generally, the February S, 200S edition of Value Line reports that its analysts anticipate an average rate of return on common equity for the electric utility Exhibi t No. 3 Case Nos AVU-E-OS-01 & AVU-G-OS-01 W. Avera, Avista Schedule WEA-2, p. 25 of 27 1 industry of 11.5 percent in 200S and over its three-to-five 2 year forecast horizon.17 Meanwhile, Value Line expects that 3 natural gas utilities will earn an average rate of return 4 on common equity of 11.5 percent in 200S and 12.0 percent 5 over the years 2010 through 2012. 18 6 For the firms in the utility proxy group specifically, 7 the returns on common equity proj ected by Value Line over Sits three-to-five year forecast horizon are shown on 9 Schedule WEA-12. Consistent with the rationale underlying 10 the development of the br+sv growth rates, these year-end 11 values were converted to average returns using the same 12 adjustment factor discussed earlier. As shown on Schedule 13 WEA-12, after eliminating potential outliers, Value Line's 14 projections suggested an average ROE of 10.5 percent for 15 the utility proxy group. 16 Q. What return on equity is indicated by the results 17 of the expected earnings approach? lS A. Based on the results discussed above, I concluded 19 that the comparable earnings approach implies a fair rate 20 of return on equity of 11.0 percent. D. Sumry of Quantitative Results 21 Q. Please sumrize the results of your quantitative 22 analyses. 23 A.
