The System is an exempt public utility holding company under the provisions of the Public Utility Holding Company Act of 1935 with investments in four operating public utility companies located in central, eastern and southeastern Massachusetts. In addition, the System has interests in other utility and several non- regulated companies. The system has 1,792 regular employees including 1,142 (64%) represented by various collective bargaining units covered by separate contracts with expiration dates ranging from March 2001 through April 2003. Accounting Policies (a) Principles of Accounting The system's significant accounting policies are described in Note 2 of Notes to Consolidated Financial Statements included in its 1997 Annual Report on Form 10-K filed with the Securities and Exchange Commission. For interim reporting purposes, the system follows these same basic accounting policies but considers each interim period as an integral part of an annual period and makes allocations of certain expenses to interim periods based upon estimates of such expenses for the year. Generally, certain expenses which relate to more than one interim period are allocated to other periods to more appropriately match revenues and expenses. Principal items of expense which are allocated other than on the basis of passage of time are depreciation and property taxes of the gas subsidiary, Commonwealth Gas Company (Commonwealth Gas). These expenses are recorded for interim reporting purposes based upon projected gas revenue. Income tax expense is recorded using the statutory rates in effect applied to book income subject to tax for each interim period. The unaudited financial statements for the periods ended September 30, 1998 and 1997, reflect, in the opinion of the System, all adjustments (consisting of only normal recurring accruals, except for a one-time charge recorded in June 1997 as described in Management's Discussion and Analysis of Financial Condition and Results of Operations) necessary to summarize fairly the results for such periods. In addition, certain prior period amounts are reclassified from time to time to conform with the presentation used in the current period's financial statements. <PAGE 7> COMMONWEALTH ENERGY SYSTEM The results for interim periods are not necessarily indicative of results for the entire year because of seasonal variations in the consumption of energy and Commonwealth Gas' seasonal rate structure. (b) Regulatory Assets and Liabilities The system's operating utility companies are regulated as to rates, accounting and other matters by various authorities, including the Federal Energy Regulatory Commission (FERC) and the Massachusetts Department of Telecommunications and Energy (DTE). Based on the current regulatory framework, the system accounts for the economic effects of regulation in accordance with the provisions of Statement of Financial Accounting Standards (SFAS) No. 71, "Accounting for the Effects of Certain Types of Regulation." Regulated subsidiaries of the System have established various regulatory assets in cases where the DTE and/or the FERC have permitted or are expected to permit recovery of specific costs over time. Similarly, the regulatory liabilities established by the system are required to be refunded to customers over time. In the event the criteria for applying SFAS No. 71 are no longer met, the accounting impact would be an extraordinary, non-cash charge to operations of an amount that could be material. Criteria that give rise to the discontinuance of SFAS No. 71 include: 1) increasing competition that restricts the system's ability to establish prices to recover specific costs, and 2) a significant change in the current manner in which rates are set by regulators from cost based regulation to another form of regulation. These criteria are reviewed on a regular basis to ensure the continuing application of SFAS No. 71 is appropriate. Based on the current evaluation of the various factors and conditions that are expected to impact future cost recovery, the system believes that its regulatory assets, including those related to generation, are probable of future recovery. As a result of electric industry restructuring, the system's retail electric companies discontinued application of accounting principles applied to their investment in electric generation facilities effective March 1, 1998. The system will not be required to write off any of its generation-related assets, including regulatory assets. These assets will be retained on the Consolidated Condensed Balance Sheets because the legislation and the DTE's plan for a restructured electric industry specifically provide for their recovery through a non-bypassable transition charge. <PAGE 8> COMMONWEALTH ENERGY SYSTEM The principal regulatory assets included in deferred charges were as follows: September 30, December 31, 1998 1997 (Dollars in thousands) Transition costs $ 34,055 $ - Maine Yankee unrecovered plant and decommissioning costs 31,574 34,908 Fuel charge stabilization 27,283 29,655 Connecticut Yankee unrecovered plant and decommissioning costs 26,007 28,566 Postretirement benefits costs 24,459 25,475 Power contract buy-out 16,116 17,609 Deferred income taxes 13,212 13,089 FERC Order 636 transition costs 6,310 7,336 Pilgrim litigation costs 5,553 5,929 Environmental costs 5,171 3,930 Yankee Atomic unrecovered plant and decommissioning costs 4,552 6,184 Seabrook related costs 2,339 4,324 Other 1,974 1,859 $198,605 $178,864 The regulatory liabilities, reflected in deferred credits in the accompanying Consolidated Condensed Balance Sheets and related primarily to deferred income taxes, were $13.4 million and $14.1 million at September 30, 1998 and December 31, 1997, respectively. In November 1997, the Commonwealth of Massachusetts enacted a comprehensive electric utility industry restructuring bill. On November 19, 1997, the System's electric subsidiaries filed a restructuring plan with the DTE. The plan, approved by the DTE on February 27, 1998, provides that the System's retail electric subsidiaries, beginning March 1, 1998, initiate a ten percent rate reduction for all customer classes and allow customers to choose their energy supplier. As part of the plan, the DTE authorized the recovery of certain strandable costs and provides that certain future costs may be deferred to achieve or maintain the rate reductions that the restructuring bill mandates. The legislation gives the DTE the authority to determine the amount of strandable costs that will be eligible for recovery. Costs that will qualify as strandable costs and be eligible for recovery include, but are not limited to, certain above market costs associated with generating facilities, costs associated with long-term commitments to purchase power at above market prices from independent power producers and regulatory assets and associated liabilities related to the generation portion of the electric business. <PAGE 9> COMMONWEALTH ENERGY SYSTEM The cost of transitioning to competition will be mitigated, in part, by the sale of the system's non-nuclear generating assets. The sale was approved by the DTE on October 30, 1998 and by the FERC on November 12, 1998 (see the "Industry Restructuring - Electric" section under Management's Discussion and Analysis of Financial Condition and Results of Operations for further discussion of the sale). The net proceeds from the sale of these assets will be used to mitigate transition costs. The system's ability to recover its transition costs will depend on several factors, including the aggregate amount of transition costs the system will be allowed to recover and the market price of electricity. Management believes that the system will recover its transition costs. A change in any of the above listed factors could affect the recovery of transition costs and may result in a loss to the system. For additional information relating to industry restructuring, see the "Industry Restructuring - Electric" section under Management's Discussion and Analysis of Financial Condition and Results of Operations. (3) Commitments and Contingencies Capital Expenditures Construction Program The system is engaged in a continuous construction program presently estimated at $248.6 million for the five-year period 1998 through 2002. Of that amount, $60.7 million is estimated for 1998. The program is subject to periodic review and revision. Acquisition On June 1, 1998, Advanced Energy Systems, Inc. (AES), a wholly-owned subsidiary of the System, acquired for $146.3 million all of the issued and outstanding shares of capital stock of Harvard University's Medical Area Total Energy Plant, Inc. subsidiary (MATEP) and all rights under customer contracts owned by Harvard University. MATEP's principal asset is a cogeneration plant that provides heating, chilled water service and electricity to several hospitals, medical research centers and teaching institutions in the 200-acre Longwood Medical Area of Boston pursuant to the contracts that were assigned to AES. The purchase price was established through a sealed-bid auction process and the transaction was initially financed with a short-term bank loan of $150 million that was subsequently reduced with the proceeds from an equity contribution from the System to AES of approximately $40 million. A permanent financing was completed on August 26, 1998 that consisted of $112.5 million in 23-year term notes at a rate of 6.92% with sinking fund payments scheduled to begin in 2003. The notes are secured by long-term contracts between MATEP and its customers. MATEP had revenues of $58 million and net earnings of $7.3 million for the fiscal year ended June 30, 1997. Results for MATEP are included in the accompanying Consolidated Condensed Financial Statements from the date of acquisition. <PAGE 10> COMMONWEALTH ENERGY SYSTEM The acquisition was accounted for under the purchase method of accounting. The purchase price was allocated based on the fair value of assets acquired and resulted in the recognition of an intangible asset amounting to approximately $31 million that is being amortized on a straight-line basis over fifteen years. Based on unaudited data, the following pro forma summary presents the consolidated results of operations for the three and nine months ended September 30, 1998 and 1997 as if the acquisition had occurred at the beginning of the years presented: Three Months Ended Nine Months Ended September 30, September 30, 1998 1997 1998 1997 (Dollars in thousands except per share amounts) Revenues $233,606 $239,386 $736,591 $806,227 Net Income Applicable to Common Shares $ 15,836 $ 9,305 $ 40,253 $ 33,835 Basic and Diluted Earnings per Common Share $ .74 $ .43 $1.87 $1.57 The pro forma results do not purport to be indicative of the results of operations that actually would have resulted had the acquisition been made at the beginning of the years presented, or of results that may occur in the future. <PAGE 11> COMMONWEALTH ENERGY SYSTEM Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations Financial Condition Capital resources of the System and its subsidiaries are derived principally from retained earnings. Supplemental interim funds are borrowed on a short-term basis and, when necessary, replaced with new equity and/or debt issues through permanent financing secured on an individual company basis. The system purchases 100% of all subsidiary common stock issues and provides, to the extent possible, a portion of the subsidiaries' short-term financing needs. These capital resources provide the funds required for the subsidiary companies' construction programs, current operations, debt service and other capital requirements. Real estate consisting primarily of a ten acre site in Cambridge, MA was sold for $22.2 million and resulted in a net gain of $10.8 million. Future plans for the site announced by the developer include a hotel, research and development facilities, laboratories, office, retail and entertainment space and housing. This project represents further economic growth in our service territory. For the current nine-month period, cash flows from operating activities amounted to approximately $69.3 million and reflect net income of $42.7 million (which includes the net gain of $10.8 million from the aforementioned sale of real estate) and noncash items including depreciation of $45.5 million and amortization of $9.5 million. The change in working capital since December 31, 1997, exclusive of cash and interim financing, amounted to $32 million and had a positive impact on cash flows from operating activities, reflecting a lower level of accounts receivable ($28.4 million) and unbilled revenues ($20.6 million) coupled with a higher level of other current liabilities ($18.1 million) and accrued taxes ($6.9 million). These factors were offset, in part, by a decline in accounts payable ($33.1 million) and a higher level of inventories ($2 million), prepaid taxes ($5.8 million) and other current assets ($1.7 million). Construction expenditures for the current nine-month period were approximately $39.1 million, including an allowance for funds used during construction (AFUDC) and nuclear fuel. Construction expenditures and the preferred and common dividend requirements of the System ($26.9 million) were funded entirely with internally-generated funds. The system, through its Advanced Energy Systems, Inc. subsidiary (AES), purchased a total energy plant (MATEP), that was formerly owned and operated by Harvard University and is located in the Longwood Medical Area of Boston, and related contracts for $146.3 million on June 1, 1998. This acquisition was originally financed through a $150 million term loan agreement. The System, pursuant to a permanent financing plan, has provided a $40 million equity contribution to AES which was financed with <PAGE 12> COMMONWEALTH ENERGY SYSTEM a 2-year term note. The permanent financing, completed in August 1998, consists of $112.5 million in 23-year term notes at a rate of 6.92% with sinking fund payments scheduled to begin in 2003. The notes are secured by long-term contracts between MATEP and its customers. It is projected that this new venture will increase system revenues by approximately $45 million in 1998 and, on average, by approximately $65 million in the years 1999 through 2002. On May 27, 1998, the System announced that three of its subsidiary companies (Commonwealth Electric Company, Cambridge Electric Light Company and Canal Electric Company) selected affiliates of Southern Energy New England, L.L.C., an affiliate of The Southern Company, to buy substantially all of their non-nuclear electric generating assets for $462 million, an amount that is six times the book value of $79 million. The sale was approved by the DTE on October 30, 1998 and by the FERC on November 12, 1998. The net proceeds from the sale of these assets will be used to mitigate transition costs. Results of Operations The following is a discussion of certain significant factors which have affected operating revenues, expenses and net income during the periods included in the accompanying Consolidated Condensed Statements of Income. This discussion should be read in conjunction with the Notes to Condensed Financial Statements appearing elsewhere in this report. <PAGE 13> COMMONWEALTH ENERGY SYSTEM A summary of the period to period changes in the principal items included in the Consolidated Condensed Statements of Income for the three and nine months ended September 30, 1998 and 1997 and unit sales for these periods are shown below: Three Months Nine Months Ended September 30, Ended September 30, 1998 and 1997 1998 and 1997 Increase (Decrease) (Dollars in thousands) Operating Revenues - Electric $ 473 0.3 % $(38,385) (7.5)% Gas 1,438 3.4 (18,385) (7.8) Steam and other 9,580 379.9 11,022 82.2 11,491 5.2 (45,748) (6.0) Operating Expenses - Fuel and purchased power (2,502) (2.6) (38,541) (13.3) Cost of gas sold (245) (1.0) (12,079) (9.4) Other operation and maintenance 13,333 22.3 (2,120) (1.1) Depreciation 2,378 19.7 4,614 11.4 Taxes - Federal and state income (1,082) (24.0) 542 2.7 Local property and other 537 8.7 (151) (0.7) 12,419 6.1 (47,735) (6.8) Operating Income (928) (5.5) 1,987 3.3 Other Income 12,554 3,692.4 12,423 630.6 Income Before Interest Charges 11,626 67.5 14,410 23.0 Interest Charges 2,703 26.8 3,929 13.0 Net Income 8,923 124.8 10,481 32.5 Dividends on preferred shares (14) (5.6) (43) (5.7) Earnings Applicable to Common Shares $ 8,937 129.5 $ 10,524 33.4 Unit Sales Electric - Megawatthours (MWH) Retail 64,504 4.9 37,261 1.0 Wholesale (82,983) (8.1) (91,105) (3.1) (18,479) (0.8) (53,844) (0.8) Gas - Billions of British Thermal Units (BBTU) Firm (425) (14.0) (4,921) (18.2) Interruptible and other (61) (6.0) 419 12.1 (486) (12.0) (4,502) (14.7) <PAGE 14> COMMONWEALTH ENERGY SYSTEM The following is a summary of electric unit sales and gas throughput for the periods indicated: Three Months Ended Nine Months Ended September 30, September 30, 1998 1997 1998 1997 Electric Sales - MWH Residential 517,615 482,030 1,369,746 1,376,795 Commercial 733,428 700,817 1,934,289 1,891,519 Industrial 113,564 117,416 329,091 327,433 Other 5,558 5,398 17,201 17,319 Total retail sales 1,370,165 1,305,661 3,650,327 3,613,066 Wholesale sales 941,029 1,024,012 2,803,404 2,894,509 Total 2,311,194 2,329,673 6,453,731 6,507,575 Gas Sales - BBTU Residential 1,480 1,466 13,243 15,123 Commercial 818 1,012 6,333 7,776 Industrial 196 393 1,363 2,663 Other 108 156 1,228 1,526 Total firm sales 2,602 3,027 22,167 27,088 Interruptible and other 959 1,020 3,876 3,457 Total sales 3,561 4,047 26,043 30,545 Transportation 1,075 498 6,474 4,627 Total throughput 4,636 4,545 32,517 35,172 Electric Revenues, Fuel and Purchased Power Costs Operating revenues from regulated operations for the current quarter and nine-month period were $8.8 million and $54.5 million lower, respectively, than the corresponding periods in 1997 due to the 10 percent rate reduction (further discussed below), decreases in electricity purchased for resale, fuel and transmission charges ($3.9 million and $38 million, respectively), and a lower level of revenues associated with demand-side management programs. The decline in these costs reflects a cost deferral of $2 million for the quarter and $31.3 million for the nine- month period in conjunction with the Company's restructuring plan as approved by the DTE. As a result of industry restructuring, the Company has unbundled its rates, provided customers with a 10 percent rate reduction as of March 1, 1998 and has afforded customers the opportunity to purchase generation supply in the competitive market consistent with the electric industry restructuring legislation further discussed below. Delivery rates are composed of a customer charge (to collect metering and billing costs), a distribution charge, a transition charge (to collect stranded costs), a transmission charge, an energy conservation charge (to collect costs for demand-side management programs) and a renewable energy charge. Electricity supply services provided by the Company include optional standard offer service and default service. Amounts collected through these various charges will be reconciled to actual expenditures on an on-going basis. Operating revenues from two non-regulated subsidiaries increased by $9.3 million and $16.1 million for the current quarter and nine-month period. Total unit sales decreased in both the current quarter and nine- <PAGE 15> COMMONWEALTH ENERGY SYSTEM month period despite increases in retail sales as wholesale sales decreased by 8.1% and 3.1%, respectively. Gas Revenues and Cost of Gas Sold Operating revenues from regulated operations decreased by $1.5 million and $29.7 million during the current quarter and nine-month period, respectively, due primarily to the considerable declines in firm unit sales. Operating revenues from an unregulated subsidiary increased by $2.9 million and $11.3 million for the current quarter and nine-month period. Also affecting revenues in both periods was a lower average cost of gas. The decrease in unit sales to firm customers reflects the impact of the milder weather conditions experienced during 1998 on all customer segments. The fluctuation in interruptible and other sales reflects the competitive market that exists today in the natural gas industry. Other Operating Expenses For the current quarter, other operation and maintenance increased by $13.3 million (22.3%) and reflects costs associated with new business development ($5.8 million), higher costs relating to the outsourcing of the information technology, telecommunications and network services function ($3 million) that includes costs associated with Year 2000 compliance, higher conservation and load management (C&LM) costs ($2.6 million), an increase in costs associated with non-regulated real estate operations ($1.5 million) and an increase in transmission charges ($1 million). These increases were partially offset by a decline in insurance and employee benefits costs ($2.3 million) and labor savings resulting from a personnel reduction program (PRP) initiated during the second quarter of 1997 ($1 million). For the current nine-month period, other operation and mainten- ance decreased by $2.1 million (1.1%) reflecting the absence of a one-time charge ($17.7 million) related to the aforementioned PRP program, labor savings realized from the PRP ($5.4 million), a reduction in insurance and employee benefits costs ($3.8 million, the absence of storm damage costs related to an April 1997 blizzard ($2 million) and a decline in the pro- vision for bad debts ($1.6 million). These decreases were offset, in part, by costs associated with new business development ($11.5 million), higher costs ($9.1 million) associated with information technology and related services as detailed above, increased C&LM costs ($2.6 million) and higher costs associated with non-regulated real estate operations ($1.2 million). Depreciation increased $2.4 million (19.7%) during the current quarter and $4.6 million (11.4%) in the nine-month period and reflects the treatment allowed for certain production plant pursuant to the electric industry restructuring legislation as well as a higher level of depreciable plant including the newly acquired MATEP facility. Federal and state income taxes decreased $1.1 million (24%) during the current quarter and increased $542,000 (2.7%) for the nine-month period reflecting the level of pretax income related to continuing operations. The tax impact from the sale of real estate ($6.3 million) was reflected as an offset to the gain from the sale in Other Income on the Consolidated Condensed Statements of Income. The increase of $537,000 (8.7%) in local property and other taxes for the current quarter was due primarily to real estate taxes associated <PAGE 16> COMMONWEALTH ENERGY SYSTEM with MATEP and higher real estate tax rates and assessments offset, in part, by a decline in payroll taxes attributable to savings realized from the aforementioned PRP. Other Income and Interest Charges During the current quarter and nine-month period, other income increased by $12.6 million and $12.4 million due to the gain from the aforementioned sale of real estate ($10.8 million net of taxes). The increase in total interest charges for the current three and nine-month periods mainly reflects higher levels of short-term borrowings, the issuance of two new series of long-term debt in September 1997 and the issuance of 23-year term notes in August 1998 partially offset by maturing long-term debt and scheduled sinking fund payments. Industry Restructuring - Electric On November 25, 1997, the Governor of Massachusetts signed into law the Electric Industry Restructuring Act (the Act). This legislation provided, among other things, that customers of retail electric utility companies who take standard offer service receive a 10 percent rate reduction and be allowed to choose their energy supplier, effective March 1, 1998. The Act also provides that utilities be allowed full recovery of transition costs subject to review and an audit process. The rate reduction mandated by the legislation increases to 15 percent effective September 1, 1999 for customers who continue to take standard offer service. A statewide ballot referendum that sought to repeal the legislation was defeated by a wide margin on November 3 of this year. The system filed a comprehensive electric restructuring plan with the DTE in November 1997, that was substantially approved by the DTE in February 1998. The divestiture of the system's non-nuclear generation assets and the entitlements associated with its purchased power contracts is an integral part of the system's restructuring plan and is consistent with the Act. While the system is encouraged with the treatment afforded net non-mitigable transition costs (which, for the system, are primarily the result of above-market purchased power contracts with non-utility generators) by the legislation and the DTE, the mandated rate reduction has had a significant impact on cash flows of the system. However, the successful results of the generation auction, as discussed below, could significantly reduce the impact that the rate reductions will have on future cash flows. In March 1997, the system had submitted a report to the DTE that detailed the proposed auction process for selling its electric generation assets and the entitlements associated with purchased power contracts. The auction process provided a market-based approach to maximizing stranded cost mitigation and minimizing the transition costs that retail customers will have to pay for stranded cost recovery. A request for bids from interested parties was issued in August 1997 and an Offering Memorandum followed in October 1997. Potential bidders examined all pertinent information related to the generating facilities and purchased power <PAGE 17> COMMONWEALTH ENERGY SYSTEM contracts in order to prepare and submit their first round of bids in mid- December. Final binding bids were submitted in May 1998. On May 27, 1998, the System announced that three of its subsidiary companies (Cambridge Electric Light Company, Canal Electric Company and Commonwealth Electric Company) selected affiliates of Southern Energy New England, L.L.C. (Southern Energy), an affiliate of The Southern Company of Atlanta, Georgia, to buy substantially all of their non-nuclear electric generating assets for approximately $462 million (subject to certain adjustments at closing). These facilities represent 984 megawatts (mw) of electric capacity and have an approximate book value of $79 million. The plants being sold include: Canal Unit 1 (566 mw) and a one-half interest in Canal Unit 2 (282.5 mw) located in Sandwich, MA and owned by Canal Electric; the Kendall Station facility (67 mw) and the adjacent Kendall Jets (46 mw), located in Cambridge, MA and owned by Cambridge Electric; five diesel generators (13.8 mw) in Oak Bluffs and West Tisbury on the island of Martha's Vineyard that are owned by Commonwealth Electric, and a 1.4 percent joint-ownership interest (8.9 mw) in Wyman Unit No. 4 located in Yarmouth, ME, also owned by Commonwealth Electric. The system continues to evaluate bids related to the purchased power contracts. The system is also evaluating the disposition of the Blackstone Station generating unit (15.3 mw) owned by Cambridge Electric and located in Cambridge, MA which is subject to a right of first offer held by Harvard University on any divestiture of the facility. On July 31, 1998, a formal divestiture filing was submitted to the FERC and the DTE that requested approval of the sale of the system's generating assets to Southern Energy and further proposes (subject to completion of the sale) that the current 10 percent rate reduction increase, effective January 1, 1999, to 12.1 percent for Commonwealth Electric and to 15.2 percent for Cambridge Electric. In addition, the companies propose to increase the retail price of standard offer service, starting January 1, 1999, from the present rate of 2.8 cents per kilowatthour (kwh) to 3.5 cents. At the same time that the price for standard offer service is increased, the transition charge for Commonwealth Electric's customers will decline from 4.08 cents per kwh to 3.13 cents and for Cambridge Electric's customers from 2.73 cents per kwh to 1.56 cents. These proposed changes, which are intended to further reduce the cost of electricity to customers, to make the market increasingly more attractive for independent power suppliers to sell electricity directly to consumers, and to reduce the system's cost deferrals associated with the pricing of standard offer service, are based on a specific allocation methodology for the net proceeds from the sale of the Canal units. On October 30, 1998, the DTE approved the system's sale of its generating assets to Southern Energy. The DTE, however, deferred ruling on the allocation of proceeds from the sale of Canal Units 1 and 2 between Cambridge Electric and Commonwealth Electric and on the rate of return to be paid to customers on the net proceeds from the sale over an eleven-year period. These issues are not expected to impact the asset sale that is scheduled to close in the fourth quarter. The FERC approved the sale on November 12, 1998. <PAGE 18> COMMONWEALTH ENERGY SYSTEM Industry Restructuring - Gas On July 18, 1997, the DTE directed the ten Massachusetts gas utilities, including Commonwealth Gas, to initiate a collaborative process that will establish guiding principles and specific procedures for unbundling rates and services for all customers. The DTE listed six principles that it considers important to the success of a competitive natural gas market that will provide safe and reliable service at the lowest possible cost to customers. The natural gas market would: (1) provide the broadest possible choice; (2) provide all customers with an opportunity to share in the benefits of increased competition; (3) ensure full and fair competition in the gas supply market; (4) functionally separate supply from local distribution services; (5) support and further the goals of environmental regulation; and lastly (6) rely on incentive regulation where a fully competitive market cannot or presently does not exist. In addition, the DTE outlined several specific issues that it expects the collaborative to address: (1) services that can be offered on a competitive basis; (2) terms and conditions of service; (3) consumer protections and social programs; (4) mitigation of gas related and non-gas related transition costs; (5) third-party supplier qualifications; and (6) curtailment principles. The DTE also suggested that the collaborative reconsider the pricing and provision of interruptible transportation services. On August 18, 1997, the DTE noted that the development of unbundling principles and procedures constitutes only a part of the effort necessary to develop full customer choice for gas service. The DTE recognized that each local distribution company will be filing a comprehensive unbundling proposal at some later date. In the interim, the DTE directed those companies that do not currently have unbundled rates, including Common- wealth Gas, to have such rates in effect no later than November 1, 1998. Commonwealth Gas and eight other gas utilities initiated the Massachusetts Gas Unbundling Collaborative (the Collaborative) on September 15, 1997, to explore and develop generic principles to achieve the goals set forth by the DTE. Collaborative participants represented a broad array of stakeholder interests including the utilities, natural gas marketers, interstate pipelines, producers, energy consultants, labor unions, consumer advocates and representatives for the DTE, the Massachusetts Attorney General's Office, and the Massachusetts Division of Energy Resources. On November 15, 1997, the Collaborative filed a status report with the DTE that outlined its progress in moving the gas industry to a more competitive structure that provides all customers with meaningful access to competitive markets consistent with public-policy objectives. The status report summarized the substantive issues that had been the subject of Collaborative discussion, including: (1) the disposition of interstate pipeline capacity; (2) the unbundling of rates; (3) customer enrollment, billing, termination, and information exchange procedures; and, (4) consumer protections, low-income discounts, and competitive supplier <PAGE 19> COMMONWEALTH ENERGY SYSTEM registration. The status report also established a schedule to implement a final unbundling plan by November 1, 1998. In accordance with that schedule, the Collaborative submitted to the DTE a Rate Unbundling Status Report on January 16, 1998. The report detailed an overall process for developing unbundled rates consistent with the DTE's rate structure goals of efficiency, fairness, simplicity, continuity and earnings stability. In response to the Collaborative's proposal, the DTE ordered Commonwealth Gas to submit, by April 15, 1998, a consensus-based settlement, or partial settlement, of unbundled rate tariffs designed according to the general concepts set forth in the report. Subsequently, the DTE granted Commonwealth Gas an extension to reach a settlement with the Collaborative's participants. On March 18, 1998, the Collaborative filed a second status report that summarized the progress made by the Collaborative since it had last updated the DTE on its activities. The Collaborative reported that it had made substantial progress in the areas of rate unbundling and terms and conditions for unbundled services. The report also described at least two policy issues, capacity disposition and cost responsibility, on which the Collaborative's participants require specific regulatory guidance before completing a comprehensive framework for the transition to a more competitive market structure. In response to the March report, the DTE issued a Notice of Inquiry to address the Collaborative's unresolved issues. On May 1, 1998, Common- wealth Gas filed initial written comments in the proceeding arguing in favor of a mandatory capacity assignment proposal. On June 8, 1998, the DTE, as part of the aforementioned Notice of Inquiry, received final comments regarding the feasibility of implementing comprehensive unbundling for all local distribution companies by November 1, 1998. On June 29, 1998, Commonwealth Gas and three other Massachusetts local distribution companies submitted unbundled rate settlements to the DTE for consideration. The DTE issued a procedural order regarding the Notice of Inquiry on July 2, 1998 which stated that the introduction of comprehensive un- bundling for all classes of customers for all local distribution companies is not feasible by November 1, 1998. The DTE stated that unbundled rates for the four local distribution companies that filed settlements on June 29, 1998 (including Commonwealth Gas) shall be in place by November 1, 1998 and that comprehensive unbundling shall be implemented no later than April 1, 1999. Also, as part of the July 2, 1998 procedural order, the DTE ordered that a set of proposed Model Terms and Conditions be submitted by the Collaborative no later than July 15, 1998. These Model Terms and Conditions were submitted on July 10, 1998 but a decision has not yet been issued by the DTE. <PAGE 20> COMMONWEALTH ENERGY SYSTEM Environmental Matters Commonwealth Gas is participating in the assessment of a number of former manufactured gas plant (MGP) sites and alleged MGP waste disposal locations to determine if and to what extent such sites have been contaminated and whether Commonwealth Gas may be responsible for remedial actions. The DTE has approved recovery of costs associated with MGP sites. Commonwealth Gas is also involved in certain other known or potentially contaminated sites where the associated costs may not be recoverable in rates. For further information on other related environmental matters, refer to the System's 1997 Annual Report on Form 10-K. New Accounting Standards In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133 (SFAS No. 133), "Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133 establishes accounting and reporting standards requiring that every derivative instrument (including certain derivative instruments embedded in other contracts possibly including fixed-price fuel supply and power contracts) be recorded on the balance sheet as either an asset or liability measured at its fair value. SFAS No. 133 requires that changes in the derivative's fair value be recognized currently in earnings unless specific hedge accounting criteria are met. Special accounting for qualifying hedges allows a derivative's gains and losses to offset related results on the hedged item in the income statement, and requires that a company must formally document, designate and assess the effectiveness of transactions that receive hedge accounting. SFAS No. 133 is effective for fiscal years beginning after June 15, 1999 and may be implemented as of the beginning of any fiscal quarter after issuance but cannot be applied retroactively. SFAS No. 133 must be applied to derivative instruments and certain derivative instruments embedded in hybrid contracts that were issued, acquired or substantively modified after December 31, 1997 and, at the company's election, before January 1, 1998. The system has not yet quantified the impacts of adopting SFAS No. 133 on its financial statements and has not determined the timing of its method of adopting SFAS No. 133. In April 1998, the American Institute of Certified Public Accountants issued Statement of Position 98-5 "Reporting on the Costs of Start-Up Activities" (SOP 98-5). SOP 98-5 provides guidance on the financial reporting of start-up and organization costs and requires that these costs be expensed as incurred. The impact of SOP 98-5 is not expected to have a material impact on the system's results of operations or financial condition. <PAGE 21> COMMONWEALTH ENERGY SYSTEM Year 2000 The Year 2000 issue is the result of computer programs being written using two digits rather than four to define the applicable year. Any computer program that has date sensitive software may recognize a date using "00" as the year 1900 rather than the year 2000. This could result in a temporary inability to process transactions or engage in normal business activities. The system has been involved in Year 2000 compliancy since 1996. The system, on a coordinated basis and with the assistance of RCG Information Technologies and other consultants, is addressing the Year 2000 issue. The system has inventoried and assessed all date sensitive informa- tion and transaction processing computer systems and determined that a substantial portion of its software needed to be modified or replaced. Plans have been developed and are being implemented to correct and test all affected systems, with priorities assigned based on the importance of the activity. The system has identified the software and hardware installations that will be necessary. All installations are expected to be completed and tested by mid-1999. The system has also inventoried its non- information technology systems that may be date sensitive, (facilities, electric and gas operations, energy supply/production and distribution), that use embedded technology such as micro-controllers and micro- processors. The system anticipates that these systems will be updated or replaced as necessary and tested by mid-1999. Modifying and testing the system's information and transaction processing systems from 1996 through 2000 is currently expected to cost $6 to $7 million, including approximately $900,000 incurred through 1997 and $1.6 million spent during the first nine months of 1998. Approximately $1.2 million is expected to be spent in the fourth quarter of this year and the balance of $2.5 to $3 million in 1999 and 2000. Year 2000 costs have been expensed as incurred and will continue to be funded from operations. The system has initiated formal communications with its significant suppliers to determine the extent to which the system may be vulnerable to their failure to correct their own Year 2000 issues. The system has not received enough responses to its survey to make an accurate assessment of the Year 2000 readiness of its suppliers. Failure of the system's significant suppliers to address Year 2000 issues could have a material adverse effect on the system's operations, although it is not possible at this time to quantify the amount of business that might be lost or the costs that could be incurred by the system. In addition, parts of the global infrastructure, including national banking systems, electrical power grids, gas pipelines, transportation facilities, communications and governmental activities, may not be fully functional after 1999. Infrastructure failures could significantly reduce the system's ability to acquire energy and its ability to serve its customers as effectively as they are now being served. The system is identifying elements of the infrastructure that are critical to its operations and is obtaining information as to the expected Year 2000 readiness of these elements. <PAGE 22> COMMONWEALTH ENERGY SYSTEM The system has started its contingency planning for critical operational areas that might be effected by the Year 2000 issue if compliance by the system is delayed. System gas and electric operations currently have emergency operating plans as well as information technology disaster recovery plans as components of its standard operating procedures. These plans will be enhanced to identify potential Year 2000 risks to normal operations and the appropriate reaction to these potential failures including contingency plans that may be required for any third parties that fail to achieve Year 2000 compliance. All necessary contingency plans are expected to be completed by early 1999, although in certain cases, especially infrastructure failures, there may be no practical alternative course of action available to the system. The system is working with other energy industry entities, both regionally and nationally with respect to Year 2000 readiness and is cooperating in the development of local and wide-scale contingency planning. While the system believes its efforts to address the Year 2000 issue will be successful in avoiding any material adverse effect on the system's operations or financial condition, it recognizes that failing to resolve Year 2000 issues on a timely basis would, in a "most reasonably likely worst case scenario," significantly limit its ability to acquire and distribute energy and process its daily business transactions for a period of time, especially if such failure is coupled with third party or infrastructure failures. Similarly, the system could be significantly effected by the failure of one or more significant suppliers, customers or components of the infrastructure to conduct their respective operations after 1999. Adverse affects on the system could include, among other things, business disruption, increased costs, loss of business and other similar risks. The foregoing discussion regarding Year 2000 project timing, effectiveness, implementation and costs includes forward-looking statements that are based on management's current evaluation using available information. Factors that might cause material changes include, but are not limited to, the availability of key Year 2000 personnel, the readiness of third parties, and the system's ability to respond to unforeseen Year 2000 complications. Forward-Looking Statements This discussion contains statements which, to the extent it is not a recitation of historical fact, constitute "forward-looking statements" and is intended to be subject to the safe harbor protection provided by the Private Securities Litigation Reform Act of 1995. A number of important factors affecting the System's business and financial results could cause actual results to differ materially from those reflected in the forward- looking statements or projected amounts. Those factors include developments in the legislative, regulatory and competitive environment, certain environmental matters, demands for capital and new business development expenditures and the availability of cash from various sources. <PAGE 23> COMMONWEALTH ENERGY SYSTEM PART II - OTHER INFORMATION Item 1. Legal Proceedings The System is subject to legal claims and matters arising from its course of business including when Cambridge Electric was an intervenor in an appeal at the Massachusetts Supreme Judicial Court (SJC) filed by the Massachusetts Institute of Technology (MIT) involving a DTE decision approving a customer transition charge (CTC) for the recovery of stranded investment costs. By its terms, the CTC was terminated on March 1, 1998, coincident with the retail access date established by the Massachusetts Legislature in the Electric Industry Restructuring Act. On September 18, 1997, the SJC remanded the CTC matter to the DTE for further consideration. The SJC stated that, although recovery of prudent and verifiable stranded costs by utility companies is in the public interest and consistent with the Public Utility Regulatory Policies Act, the insufficiencies of the DTE's subsidiary findings precluded the SJC from undertaking a meaningful review of the DTE's calculations that formed the basis of the CTC. The DTE is in the process of determining whether to hear additional evidence in the remand or to rely on the record and pleadings already filed. On January 16, 1998 Cambridge Electric submitted to the DTE a customer exit charge rate tariff and sought a finding that the tariff would apply to MIT. On July 23, 1998 the DTE issued a ruling which rejected the form of customer exit charge rate tariff, but opened a new investigation into whether MIT should be required to pay an exit charge, and, if so, what the amount of the exit charge should be. Also, the DTE's investigation includes whether this case should be joined with the remand proceeding currently before the DTE. This issue is discussed more fully in the System's 1997 Annual Report on Form 10-K. At this time, management is unable to predict the ultimate outcome of this proceeding. Item 2.
