Rate of Return GMCLP is asking the Régie to allow a rate of return on common share equity of 10.47%. The distributor is also requesting approval of a regulatory framework that includes a formula for simplifying the annual establishment of the rate of return on common shareholders’ equity. There was also a third request concerning the approval of a new performance incentive mechanism based on improvement of the distributor’s long-term operating performance; however, this request was deferred to a subsequent phase, the format and timetable of which remain to be determined. This topic will be covered subsequently in this decision. 7.1 Business Risks 7.1.1 Evidence and Argumentation As submitted by GMCLP57, the Partnership is exposed to various risks and, while it wants to minimize and manage those risks, its compensation should take them into account. It faces three main types of risks – business risk, financial risk and regulatory risk. In GMCLP’s view, its business risk will be greater for the current year and greater than that of its peers. On the one hand, in terms of the application, the distributor feels its competitive position will become increasingly difficult in relation to fuel oil and more vulnerable because of its high concentration of industrial customers. On the other hand, the upcoming renegotiation of a large number of expiring transportation and storage contracts, while presenting opportunities, causes the distributor certain concern. GMCLP considers its operating risks will not be 57 GMCLP-14, Document 1 different than the current year or substantially different than for other intervenors in the industry. The financial risks are of a different nature, the most important being interest and foreign exchange fluctuations, and counterparty risk. GMCLP considers that, in spite of the present crisis in Asia, the financial risk will be basically comparable to the current year. Furthermore, it considers that most of the financial risks to which it is exposed are similar to those faced by its competitors. In terms of regulatory risk, which is consequent upon the uncertainty related to recent regulatory changes, it considers it is slightly greater as the new Régie de l’énergie brings with it certain uncertainty as to the continuity of treatments allowed in the past. When all is said and done, GMCLP feels that, in light of the various aforementioned risks, its overall risk is greater than the current year, which is already slightly greater than the overall risk for Ontario distributors, as acknowledged by the Régie in Decision D-96-3158. According to certain intervenors, the situation described by GMCLP paints too sombre a picture of the distributor’s overall risk. The ACIG feels the business risk is only marginally greater than for comparable businesses in Canada and that this risk is totally offset by clearly more favourable regulatory treatment, long-term contracts signed by most large industry customers, the diversification and increase in the number of suppliers as well as by a higher than average capitalization ratio for Canadian distributors. Accordingly, the ACIG does not share GMCLP’s position and considers that a number of developments this year improve the distributor’s risk profile. In terms of comparison with other Canadian distributors, this intervenor suggests, based on studies submitted by its expert, that GMCLP’s overall risk is totally comparable to that of Westcoast and BC Gas, and marginally greater than the risk faced by Consumers Gas. Basically similar positions are taken by Option Consommateurs CAMSS and ROEE, reiterating the arguments to the effect that regulatory tools approved by the Régie to protect and develop the Quebec, and the non-regulatory mechanisms reduce or even distributor’s risks. and FNACQ, the numerous gas market in eliminate the 7.1.2 Régie’s Opinion In the Régie’s view, based on the various issues that affect the Partnership and that may have repercussions on its financing strategy, the distributor’s business risk for the coming year is at most the same as for the current year. 58 Decision D-96-31 rendered on October 9, 1996 (Case 3351-96) Concerning business risk, in the Régie’s opinion the numerous regulatory or other tools, such as long-term contracts, presently available to GMCLP as well as the conservation of the dual-energy tariff flexibility program and the reactivation of the flexibility program for Tariffs 1, 3 and M, approved in this decision, enable GMCLP to act promptly and adequately when certain volumes might be threatened. Moreover, the Régie considers that the approval of an additional budget of $400,000 to review the supply portfolio should make it possible for GMCLP to identify and optimize existing or future opportunities and thereby contain the supply risk to at least a similar level as it faces at present. The Régie agrees with the distributor’s positions that the operating and financial risks are the same as the current year. Irrespective of the changes, the Régie feels the regulatory risk will be basically identical to the present year. The regulatory framework remains essentially unchanged, with a rate structure that takes account of the distributor’s cost of service and a framework adapted to the needs of the customers and the Partnership. Furthermore, the decisions already rendered in the preceding sections and in other decisions reflect the regulator’s continuing concern with the distributor’s financial and operating health and confirm its desire, through its approval of various automatic adjustment mechanisms, to lighten and simplify the regulatory process. The Régie also wants to point out that, in its opinion, the speed with which a number of decisions have been issued over the past few months in the natural gas field, either for system extension requests or on other matters, also considerably reduce some of the uncertainties that recent regulatory changes might have generated. In terms of comparative risk, the Régie shares GMCLP’s opinion that its risk is considerably greater than that of Ontario distributors. For the reasons stated, the Régie therefore feels the Partnership’s business risk, based on the different risks mentioned, is also the same as for the current year. 7.2 Access to Capital 7.2.1 Evidence and Argumentation According to GMCLP, the present capital structure enables it to minimize the cost of capital. It feels it needs a credit rating of at least A59 to facilitate access to capital markets and avoid restrictive periods. Considering its financial requirements over the next few months, GMCLP therefore places great importance on maintaining an acceptable rating and prudently suggests that the interest coverage required by CBRS is still relatively higher than the average. As the financial markets require interest coverage between 2.0X and 3.2X for an A rating, GMCLP’s present 2.82X places it, in its view, at a normal enough level with a slightly higher risk than its peers. In GMCLP’s view, if the Régie adopted 59 Shorthand notes of October 27, 1998, volume 4, page 56 the ACIG’s recommendation of an 8.25% rate of return, the ratio would fall to 2.5X60, i.e. at the low end of the A rating standards. Contrary to GMCLP’s position, the ACIG feels the interest coverage ratio was more in the order of 2.5X for 1993 to 1997 inclusively, and even 2.4X for 1994 and 1995, i.e. the same coverage ratio that would result from this intervenor’s recommendation. The ACIG also points out that GMCLP’s ratings have been a model of stability over the past few years and that, when considered overall, the Company’s financial ratios largely justify an A-high rating61. 7.2.2 Régie’s Opinion With a business risk that is slightly greater than for Ontario distributors, and considering that CBRS has given most natural gas distributors and transporters in Canada have an A rating, in the Régie’s opinion, GMCLP has to maintain a credit rating between A and A-high in order to continue to have reasonable access to capital markets and reduce its financial costs. This position had already been clearly stated in Decision D-96-31. It is therefore necessary to maintain a credit rating between A and A-high because this rating has made it possible for GMCLP to significantly reduce its financial costs and have greater access to financial markets.62 Based on the arguments heard, the Régie feels this means that an interest coverage ratio around the average of the CBRS standards, i.e. between 2.0X and 3.2X, should be sufficient to justify maintaining an A rating, especially if GMCLP exceeds the CBRS’ standard criteria, e.g. amount of common equity, debt weighting and cash versus total debt, continue to be met. 7.3 Risk-free Bond Rate 7.3.1 Evidence and Argumentation As any regulatory system is forward-looking by nature, GMCLP advocates the adoption of the average forecasts, for 3 and 12-month periods, in the Consensus Forecasts63 to evaluate the rate of return of Canada 10-year bonds with the addition of the spread between 10 and 30-year bonds. Following the initial submission of GMCLP’s application using projected longterm rates of 6.02% based on the March 1998 edition, the distributor revised the risk-free bond rate to 5.759% based on the August projections. 60 GMCLP-14, Document 1.23. Shorthand notes of October 27, 1998, Volume 4, pages 168-170 62 Decision D-96-31 rendered on October 9, 1996, page 67 63 Shorthand notes of October 27, 1998, volume 4, pages 86, 199-204 61 The ACIG’s expert witness testified64 that he had not used the bond spot rate to establish his rates between 5.75% and 6.25%, but that he had made certain forecasts, taking into consideration a number of factors, including the spread between Canada and U.S. long-term bonds. 7.3.2 Régie’s Opinion While the rate case taken as a whole is forward-looking in nature, it nevertheless remains important that the forecasts used be representative of reality. Based on the testimony and the answers to questions asked, in the Régie’s opinion, the Schedule in Exhibit GMCLP-15, Document 2.14 satisfactorily shows that the use of Consensus Forecasts’ projections is justified. The differences between forecast and actual rates for the past five rate cases were reasonable and both positive and negative, depending on the years, thereby showing they can be considered a representative approximation of reality. The Régie therefore maintains the utilization of the most recent Consensus Forecasts for determining, in the rate cases, the risk-free bond rate, considering in addition that such use will facilitate the implementation of the indexing mechanism. The Régie therefore notes, for the present rate case, a risk-free bond rate of 5.759%. 7.4 Risk Premium 7.4.1 Evidence and Argumentation As stated by GMCLP’s expert, there are four fundamental methods for determining a fair and reasonable rate of return. Three of them rely on market data, i.e. the Discounted Cash Flows (DCF) method, the Risk Premium method and the Capital Asset Pricing Model (CAPM) method. The fourth method involves using accounting data to estimate the income of comparable enterprises. The two experts called by GMCLP and the ACIG respectively only used the Risk Premium method and/or the CAPM method. However, GMCLP’s expert established an average risk premium using three additional methods, i.e. the CAPM empirical version, the History of U.S. Distributors and the Future for U.S. Distributors. On the initial basis of a market risk premium evaluated at 6.50% and an adjusted beta of 0.65, a risk premium of 4.50%, including 30 points for issue costs, was calculated. Considering the results of the three other sub-methods used by 64 Shorthand notes of October 28, 1998, volume 5, pages 32-33. GMCLP’s expert, an average risk premium of 4.55% was initially submitted, and then subsequently revised to 4.71%. The ACIG’s expert only used the CAPM method and, based on different historical studies, determined, on the basis of a market premium evaluated at 4.50% and a gross beta of 0.50, a risk premium of 2.25% for GMCLP, plus 25 points for other factors such as issue costs. The ACIG’s expert did not retain the CAPM empirical version or the methods that treat risk premiums of U.S. companies. Thus, according to the experts heard, the distributor’s average risk premium could be between 2.50% and 4.71%. The experts did not use the exact same historical studies to compare the behaviour of the stock and long-term bond markets. Furthermore, they used two different methods to calculate the average value of the reference market risk premium. Similarly, these experts did not agree on the degree of volatility, or beta coefficient, which should be taken into account. GMCLP suggests the arithmetic average65 is the only appropriate factor to use for evaluating the expected return of an investor in the future, based on present conditions. The ACIG however, suggests that given the fact the rates of return earned by regulated enterprises do not vary to any great extent, compared to the market in general, it would be more appropriate to use the geometric average66. To measure the behaviour of public utilities compared to the market in general, GMCLP proposes using an adjusted beta of 0.65 on the premise that corporate betas tend to move towards maturity or the average, i.e. 1.0. According to their expert67, companies that have betas that vary from 1.0, due to special portfolio policies, will tend to come closer to each other through their dividend, debt and marketing policies. The ACIG’s expert concludes68 that the securities of the Lowest Risk Utilities group are twice as less volatile than the market in general, which equates to a gross beta in the order of 0.50. This estimate is based on a sample of ten companies, including five telephone companies. In terms of the other factors, including issue costs, there were also diverging opinions. GMCLP suggests these costs are in the order of 30 basis points, whereas the ACIG claims they are 25 basis points. 7.4.2 Régie’s Opinion 65 Shorthand notes of October 27, 1998, Volume 4, pages 91-95. ACIG-2, Document 1: Written evidence of William R. Waters, September 1998, Appendix VIII 67 Shorthand notes of October 27, 1998, Volume 4, pages 72-73. 68 ACIG-2, Document 1: Written evidence of William R. Waters, September 1998, page 40 and Schedule 8. 66 In rendering a decision on the reasonable rate of return to allow on Partners’ common equity in accordance with Section 49 of the Act, the Régie takes into consideration, among other things, the following factors – the Partnership’s financial context, its business risk, the economy in general, interest rates and the return on long-term bonds, the rate of return estimation methods presented by the experts, the regulatory context in neighbouring jurisdictions, and maintaining the financial integrity of the Partnership. While the estimate of a reasonable rate of return must be based on methods that are objective or that the validity thereof has been sufficiently proven in practical terms, the Régie is aware that the numerous assumptions made make the results somewhat subjective. In addition, although the Régie will establish estimates it has retained in this section, the exercise and the results thereof have to be considered as a reflection of the Panel’s assessment of the evidence submitted. In other circumstances and based on the evidence submitted in other instances, the Régie may have to revise these estimates. The Régie will indicate to what extent and in what form the technical estimates used have to be used in establishing a reasonable rate. To begin, the Régie notes that the implicit risk premium of 4.71% requested by GMCLP in this case is the highest it has submitted to the Régie in the past seven years. The Régie therefore undertook its review of GMCLP’s application with a great deal of care. As stated by the expert witnesses, the Régie is also of the opinion that greater weighting of risk premium and CAPM-type methods is appropriate for determining a fair and reasonable return. While GMCLP had also used U.S. financial market data in its approach, the Régie considers that Canadian data are more representative of capital markets and taxation in Canada. However, it agrees that with the integration of international financial markets, it might be reasonable to take account of U.S. data, albeit giving them less weight. In terms of the method to use for analyzing historical data, the Régie considers that the geometric average is useful for evaluating the constant rate of return that it would have been necessary to earn each year in order to obtain a given overall return over a historical investment period. To evaluate the expected overall market return for a projected year, in the Régie’s opinion the arithmetic average is more appropriate because the objective is to evaluate the average market risk premium and because actual returns earned on the market are, by their very nature, uncertain. Consequently, the arithmetic average of the historical returns is more suitable for evaluating the expected overall market return for a projected year, because it evaluates the expected future value, based on the breakdown of the realization probabilities of all returns. The Régie therefore concludes that the arithmetic average is more appropriate for establishing the market risk premium and the rate of return based on the risk premium and CAPM methods. Moreover, the Régie weighs the five methods submitted by GMCLP for estimating the market risk premium using factors of 80% for the Canadian studies and 20% for the U.S. studies. This weighting produces a market risk premium of 6.44%. Based on the evidence submitted in the case, a majority of the recognized investment houses, like Value Line69, Bloomberg and others, publish adjusted betas as part of their market returns analyses. However, this beta trend towards 1.0 is not as obvious for regulated sectors like the distribution of natural gas. The ACIG’s evidence70 in effect makes it possible to question the relevance of the unqualified use of the general adjusted betas theory for regulated enterprises. If GMCLP’s beta cannot be measured directly, the experts should use estimates based on either a sample of comparable companies or general studies. As the evidence in the case does not make it possible to directly evaluate GMCLP’s beta, the Régie retains, in the application of the CAPM, a beta of 0.55, which corresponds to the maximum limit of the ACIG expert’s witness, for the regulated entities in question. On the basis of a risk premium of 6.44% and a beta of 0.55, the CAPM estimate of GMCLP’s risk premium is 3.54%. The Régie’s retention of the 30 basis points adjustment to take account of issue costs and other factors (flotation costs) produces a structural risk premium of 3.84%. This compares to the 3.4% estimated by the Ontario Energy Board for Consumers Gas (EBRO 495) and the 3.0% estimated in March 1995 by the NEB (RH-2-94) for regulated pipeline companies. Adding the risk-free rate of 5.759%, i.e. the forecast return for Canada long-term bonds by Consensus Forecasts, adjusted for a 30-year maturity, to this structural risk premium of 3.84% produces a rate of return on equity for the shareholders of GMCLP of 9.60% for the 1999 year. 8. Automatic Mechanism for Establishing Rate of Return 69 70 Value Line Investment Survey, GMCLP-15, Document 2.43 ACIG-2, Document 1, Written Evidence of William R. Waters, September 1998, Appendix V, Table 1. 8.1 Evidence and Argumentation Based on the Régie’s desire to improve the regulatory process, GMCLP proposes that the Régie adopt, for the next five years, an automatic adjustment formula for the rate of return on shareholders’ common equity based on risk-free interest rates, as measured by the average return on Canada long-term bonds. The calculation of the target rate of return would be made in August each year and would reflect the change in interest rates between the base year and the reference year. In order to relate the rate of return to interest rates, a risk premium-based formula is proposed. To establish the base forecast for risk-free interest rates, GMCLP proposes using the average of the forecasts established over 3 and 12-month periods for the longterm return on Canada 10-year bonds, published in Consensus Forecasts in August each year and adding to this 10-year rate the spreads between 10 and 30year bonds for the preceding July. According to the distributor, using the August Consensus Forecasts is justified by the fact that it is the latest forecast available before the start of the rate year, i.e. October 1. Moreover, using the Consensus Forecasts for the same month each year (August) should make it possible to have a constant reference point year after year. Use of the August forecast by GMCLP would enable it to take account of the rates forecast at the end of the second month (November) and the eleventh month (August) of the projected reference year, thereby generating average rate forecasts almost perfectly centred on the reference year. Based on his studies, GMCLP’s expert witness suggests there is a negative relationship between the risk premium and interest rates71. His analyses lead him to conclude that for a change of 100 basis points (1%) in government bond rates, the risk premium changes by 25 basis points in the opposite direction, for a net change of 75 basis points. In other words, GMCLP is suggesting that the elasticity factor that should be used to adjust the risk premium is in the order of 75%. In its request for approval and implementation of this automatic adjustment mechanism for a period of five years, GMCLP acknowledges that, to protect customers and investors, it is desirable to have a review process for the base formula related to bond interest rate fluctuations. Accordingly, the distributor suggests, if the risk-free rate deviates by 300 basis points from the reference point of approximately 6.0% (March 1998), i.e. if the Canada long-term bond return exceeds a range of 3% to 9%, that GMCLP can request changes to the formula for setting the rate of return. As for the proposed five-year period in Exhibit GMCLP-15, Document 2 for the written questions72 and then at the hearings73, GMCLP’s expert witness stated 71 72 GMCLP-15, Document 2, Appendix B, pages 17-21. GMCLP-15, Document 2.2. that, although he wanted a long-enough period to allow the mechanism to function, he would not disagree that the regulatory system be reviewed in three years rather than five years. None of the intervenors objected to introducing such an automatic adjustment mechanism for the rate of return to reflect fluctuations in long-term interest rates. However, the ACIG disagreed with the terms and conditions of the mechanism and the market conditions that would justify holding new hearings to re-evaluate GMCLP’s return. Firstly, according to the ACIG’s expert, in the case of an automatic mechanism, the Consensus Forecasts’ forecasts appear to him, when all is said and done, to be of no value and he would even be satisfied with the use of the bond market spot rate in the indexing mechanism74. Moreover, with respect to the elasticity factor, the ACIG’s expert suggests there is a historical relationship, at a certain bond rate, i.e. less than 10%, that investors in public utilities accept smaller premiums to own shares rather than bonds. In his opinion75 and analyses76, for any interest rate below 10%, there is no elasticity factor; therefore, if Canada long-term bonds increase by 100 basis points, the rate of return should be increased by 100 basis points. According to the ACIG, a review of the adjustment mechanism should be justified by changes in market parameters. This intervenor therefore suggests that the automatic adjustment mechanism for the rate of return be reviewed in the event long-term interest rates creep above 8% and stay at that level for a period of six months. In this expert’s view, such an increase would then in all likelihood be the result of a significant change in the economic environment in which the distributor operates and would justify a review of the mechanism in place. 8.2 Régie’s Opinion In Section 7.3 of this decision, the Régie stated that the use of the most recent Consensus Forecasts’ forecast was appropriate for determining the risk-free bond rate. GMCLP’s arguments in terms of its objectives appear valid to the Régie in the sense that data taken from Consensus Forecasts are neutral, objective and representative of the rates that, according to the forecasts prepared, should prevail during the period the tariffs apply. With respect to the use of the spot rate, the Régie considers that the evidence in the case allows it to conclude that their use would significantly improve the quality of the forecasts. 73 Shorthand notes of October 27, 1998, Volume 4, pages 255-256. Shorthand notes of October 28, 1998, Volume 5, page 33. 75 Id., pages 48-50. 76 ACIG-2, Document 1, pages 28-31. 74 Accordingly therefore, the Régie approves, as the first item of the automatic mechanism for establishing the rate of return, the use of Consensus Forecasts’ August forecasts of each year to determine the risk-free bond rate in accordance with the methodology retained. This rate will be established using the average of the two published forecasts of the long-term Canada 10-year bond rates over future 3 and 12 month periods. The average spread between the actual 10 and 30 year rates the preceding July will be added to this rate. The spread is based on published bond rates. While no method of estimating the cost of capital of regulated enterprises can perfectly reproduce investors’ expectations, the Régie retains that the use of an elasticity factor, reflecting a potential relationship between long-term bond rates and the return expected by shareholders, remains the most widespread practice. Such practice has the advantage of taking into account the fact that investors’ short-term expectations do no necessarily vary directly with the change in the return on bonds. Moreover, the results using this approach should be neutral over longer periods. Accordingly, for the automatic mechanism for establishing the rate of return, the Régie retains the use of an elasticity factor of 75% to adjust GMCLP’s rate of return, the base level of the long-term interest rates being established at 5.76%. The Régie also notes that, during the testimony, certain reservations about the use of an automatic formula for periodically adjusting the rate of return were expressed and that different parameters, for limiting or justifying possible interventions before the Régie, were suggested. In the Régie’s opinion, such an adjustment mechanism will effectively only be useful and valid if, while ensuring the distributor maintains a healthy financial condition, the review rules and circumstances are clear for all interested parties. Thus, on the one hand, taking into consideration that the distributor has to be able to react adequately to unfavourable economic and financial conditions that could arise in the markets during the indexation period, and, on the other hand, that the Régie wants to lighten the regulatory process, the Régie concludes that the present adjustment mechanism for the rate of return will have to be reviewed and, if necessary, adjusted, in the event Canada long-term bond interest rates rise above 8% for a consecutive six-month period. Considering that this automatic mechanism for establishing the rate of return on shareholders’ equity is fair and will simplify the process of determining this rate and consequently reduce the related costs and time, the Régie approves, for an initial period of three years, this new regulatory framework in accordance with the aforementioned terms. Accordingly, for the 1999-2000, 2000-2001 and 2001-2002 rate cases inclusively, the rate of return on the common shareholders’ equity of GMCLP will be determined, rounded to two decimal points, based on variations in risk-free bond rates as published in August each year by Consensus Forecasts, adjusted for the spread between the returns on 10 and 30 year bonds and an elasticity factor of 75%. 9. Capital Structure and Average and Prospective Cost of Capital 9.1 Evidence and Argumentation Over the past few years, GMCLP has stated on numerous occasions that its present capital structure was optimal in that it minimizes the cost of capital and permits access to capital markets at a competitive cost. The distributor refers to previous testimony and decisions, including D-96-31, to state that no exceptional circumstance has occurred or is foreseen that would justify revising the historical capital structure, which is composed of 38.5% common equity, preferred equity of 7.5% of total capitalization and 54% debt. GMCLP therefore intends to maintain this “optimal” capital structure. The distributor is therefore asking the Régie to allow, for the 1998-1999 year, an average cost of capital of 9.07% as a rate of return on the rate base and to initially approve a prospective cost of capital of 7.84% for evaluating planned investment projects by GMCLP during that year. None of the intervenors directly questioned this capital structure. However, the ACIG pointed out that GMCLP has a higher than average financial structure compared to other distributors in Canada, due to a greater proportion of equity and lower proportion of debt. According to that intervenor, such a structure would reduce the financial risks. GMCLP contests this position claiming the distributor’s greater business risk resulted in a slightly higher equity level and not the opposite. 9.2 Régie’s Opinion The Régie considers there are no exceptional circumstances that justify revising GMCLP’s present capital structure and therefore maintains this structure that it still considers optimal for the distributor’s sound financial health and to allow it access to capital markets at a competitive cost. Therefore, based on a financial structure of 38.5% common shares, 7.5% deemed preferred shares and 54% debt and an authorized rate of return on shareholders’ equity of 9.60%, the Régie allows, for the 1998-1999 fiscal year, an average cost of capital and a rate of return on the rate base of 8.74%. Similarly, it approves for the same period a prospective cost of capital of 7.47% for evaluating investment projects.
