Item 1. Business General Commonwealth Electric Company (the Company) has been engaged in the generation, transmission, distribution and sale of electricity to approximate- ly 327,000 retail customers (including 45,500 seasonal) in 40 communities located in southeastern Massachusetts, including Cape Cod and the island of Martha's Vineyard, having an approximate year-round population of 549,000 and a large influx of summer residents. The results of the 1990 federal census taken in the Company's service area indicated a population increase of 18.1% since 1980. The Company also sells power to the Independent System Operator (ISO) - New England (the agency that operates a centralized facility to ensure reliability of service and dispatch of economically available generating units throughout New England), and is actively marketing sales of certain available capacity to other utilities in and outside the New England region. In early 1997, the Company received approval to participate as a broker in the purchase and sale of electricity. The Company, which was organized on April 4, 1850 pursuant to a special act of the legislature of the Commonwealth of Massachusetts, operates under the jurisdiction of the Massachusetts Department of Telecommunications and Energy (DTE) that regulates retail rates, accounting, issuance of securities and other matters. In addition, the Company files its wholesale rates with the Federal Energy Regulatory Commission (FERC). Since the date of its organization, the Company has from time to time acquired or disposed of the property and franchises of or merged with various gas or electric companies. The Company is a wholly-owned subsidiary of Commonwealth Energy System (the Parent), which, together with its subsidiaries, is collectively referred to as "COM/Energy." In response to the significant changes that have taken place in the electric utility industry, the Company sold all of its generating assets in late 1998 to focus on the transmission and distribution of energy and related services. For additional information, refer to the "Restructuring Legisla- tion" section under the "Rates, Regulation and Legislation" section of this Item 1. In December 1998, the Parent signed an Agreement and Plan of Merger with BEC Energy, the parent company of Boston Edison Company, that will create an energy delivery company serving approximately 1.3 million customers located entirely within Massachusetts including more than one million electric customers in 81 communities and 240,000 gas customers in 51 communities. The merger is expected to occur shortly after the satisfaction of certain condi- tions, including receipt of certain regulatory approvals. The regulatory approval process is expected to be completed during the second half of 1999. By virtue of its charter, which is unlimited in time, the Company has been involved in the production, purchase, distribution and sale of electricity without direct competition in kind from any privately or municipally-owned utilities. Alternate sources of energy are available to customers within the service territory, but competition from these sources has not been signifi- cant. However, on November 25, 1997, the Governor of Massachusetts signed into law the Electric Industry Restructuring Act that subjects the generation <PAGE 4> COMMONWEALTH ELECTRIC COMPANY element of traditional electric utility operations to competition effective March 1, 1998, and further allows consumers for the first time to choose their electric energy supplier. While competition to provide electric supply has not yet achieved the starting point for residential customers in Massachu- setts, several of the Company's commercial and industrial customers (as of March 1999) are already buying power in the competitive market. For addition- al information, refer to the "Unbundled Rates" section under the "Rates, Regulation and Legislation" section of this Item 1. Of the Company's 1998 retail electric unit sales (70.6% of total sales), 47.1% was sold to residen- tial customers, 42.0% to commercial customers, 10.4% to industrial and 0.5% to streetlighting and similar types of customers. Electric Power Supply The Company sold its generating assets that consisted of five diesel generators (13.8 megawatts (MW)) in Oak Bluffs and West Tisbury on the island of Martha's Vineyard that were principally used for emergency and peaking purposes and a 1.4 percent joint-ownership interest (8.9 MW) in Central Maine Power's Wyman Unit No. 4 located in Yarmouth, ME, to an affiliate of The Southern Company of Atlanta, Georgia effective December 30, 1998. The Company now relies entirely on purchased power to meet its electric energy require- ments. The sale was the result of an auction process initiated during 1997 in response to electric industry restructuring legislation enacted in Massachu- setts in November 1997. For additional information, refer to the "Restructur- ing Legislation" section under the "Rates, Regulation and Legislation" section of this Item 1. Power purchases for the Company and Cambridge Electric Light Company (Cam- bridge Electric), the other wholly-owned electric distribution subsidiary of the Parent, are arranged in accordance with their requirements. These arrangements have included purchases from Canal Electric Company (Canal Electric), another wholly-owned subsidiary of the Parent. These purchases included power generated at Canal Electric's generating facilities located in Sandwich, MA, which were also part of the aforementioned auction and sale. However, Cambridge Electric and the Company continue to purchase energy and capacity under a series of long-term contracts, and these entitlements include one-quarter (139.8 MW) of the capacity and energy of Canal Unit 1, which is now purchased from the new plant owner, Southern Energy Canal, L.L.C. (South- ern). The Company's entitlement in Unit 1 is 111.1 MW. The Company's and Cambridge Electric's cost of service agreements with Canal Electric for one- half (275.7 MW) of the capacity and energy purchased from Canal Unit 2 were terminated as part of the generating asset sale on December 30, 1998. The Company's entitlement in this unit was 220.7 MW. The former Unit 2 agreement was replaced by a new agreement under which Southern sells energy and capacity to the Company to support its customer load obligation, at fixed rates that are equivalent to the Company's standard offer (wholesale) rates. Pursuant to a Capacity Acquisition and Disposition Agreement (CADA), Canal Electric seeks to secure bulk electric power on a single system basis to provide cost savings for the customers of the Company and Cambridge Electric. The CADA has been accepted for filing as an amendment to Canal Electric's FERC rate schedule and allows Canal Electric to act on behalf of the Company and Cambridge Electric in the procurement of additional capacity for one or both companies, or, to sell capacity and/or energy from each company's entitle- ments. The CADA is in effect for Seabrook 1 and Phases I and II of Hydro- Quebec. Exchange agreements are in place with these utilities whereby, in certain circumstances, it is possible to exchange capacity so that the mix of power improves the pricing for dispatch for both the seller and the purchaser. <PAGE 5> COMMONWEALTH ELECTRIC COMPANY Power contracts are in place whereby Canal Electric bills or credits the Company and Cambridge Electric for the costs or revenues associated with these facilities. The Company and Cambridge Electric, in turn, have billed or are billing these charges (net of revenues from sales) to their customers through rates subject to DTE approval. The Company has other long-term contracts for the purchase of electricity from various other sources including a 73.1 MW entitlement from a nuclear unit in Plymouth, MA (Pilgrim) under a life-of-the-unit contract with Boston Edison Company. The Pilgrim unit is expected to be sold by Boston Edison Company in 1999 to Entergy Nuclear Generating Company. In conjunction with this sale, the Company has reached an agreement to buy out of this contract, but will continue to buy power on a declining basis through 2004. Also, through Canal Electric's equity ownership in Hydro-Quebec Phase II and its 3.52% interest in the Seabrook nuclear power plant, the Company has entitlements of 48.2 MW and 32.8 MW, respectively. Pursuant to other long-term contracts, several non-utility generating (NUG) sources provided a substantial portion of the Company's power entitle- ments in 1998 as follows: 180.5 MW from four (4) natural gas-fired units; 67 MW from a waste-to-energy unit (including an expansion unit); and 23.4 MW from four (4) hydro-electric suppliers. In early 1995, the Company restructured a NUG power sale agreement with Lowell Cogeneration Company L.P. (23 MW) that defers the purchase of capacity and energy until December 31, 2000 and, when called back into service, power will be dispatched only when needed at the discretion of the Company. Also, the Company terminated a NUG power sale agreement with Pepperell Power Associates L.P. (38 MW) effective January 27, 1995. This buy-out is expected to save the Company's customers approximately $37 million over the next 20 years. In June 1995, the Company signed an agreement that terminates in 1999 with another New England utility (Northeast Utilities) to purchase peaking- unit capacity at rates lower than that available from ISO - New England or other regional utilities. In addition to power purchases, the Company has aggressively pursued the opportunity to market excess energy and capacity at rates greater than it would receive from sales to ISO - New England. This competitive business developed for the Company in the early 1990's when it began to formally respond to requests for proposals to supply short-term energy and associated capacity to other utilities. There has been increased emphasis on the marketing of excess energy and capacity as well as increased emphasis on reducing production cost expenses through aggressively seeking least-cost energy and capacity on the market. ISO - New England The Company, together with other electric utility companies in the New England area, is a member of ISO - New England (formerly the New England Power Pool (NEPOOL)), which was formed in 1971 to provide for the joint planning and operation of electric systems throughout New England. ISO - New England operates a centralized dispatching facility to ensure reliability of service and to dispatch the most economically available generating units of the member companies to fulfill the region's energy <PAGE 6> COMMONWEALTH ELECTRIC COMPANY requirement. This concept is accomplished by use of computers to monitor and forecast load requirements. The Company and the Parent's other electric subsidiaries are also members of the Northeast Power Coordinating Council (NPCC), an advisory organization that includes the major power systems in New England and New York plus the provinces of Ontario and New Brunswick in Canada. NPCC establishes criteria and standards for reliability and serves as a vehicle for coordination in the planning and operation of these systems. The reserve requirements used by the ISO - New England participants in planning future additions are determined by ISO - New England to meet the reliability criteria recommended by NPCC. COM/Energy estimates that, during the next ten years, reserve requirements so determined will be approximately 20% of peak load. Energy Mix The Company's energy mix, which includes purchased power, is shown below: 1998 1997 1996 Natural gas 33% 33% 39% Oil 42 37 21 Nuclear 14 13 20 Waste-to-energy 9 11 12 Hydro 2 6 8 Total 100% 100% 100% The Company's energy mix reflects the use of natural gas and other fuels due to the requirement to purchase capacity from NUG facilities. The higher oil component in 1998 and 1997 reflects the greater availability of Canal Units 1 and 2 as compared to 1996 when significant scheduled and unscheduled maintenance resulted in reduced output. Rates, Regulation and Legislation The Company operates under the jurisdiction of the DTE, which regulates retail rates, accounting, issuance of securities and other matters. In addition, the Company files its wholesale rates with the FERC. (a) Restructuring Legislation 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 legisla- tion 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, 1998. The Company, together with Cambridge Electric and Canal Electric, had <PAGE 7> COMMONWEALTH ELECTRIC COMPANY 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 COM/Energy's generation assets and the entitlements associated with purchased power contracts through an auction process was an integral part of the restructuring plan and is consistent with the Act. While the Company is encouraged with the treatment afforded net non-mitigable transition costs (which, for the Company, 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 Company. However, the successful sale of the generating assets, as discussed below, will reduce the negative impact that the rate reductions will have on future cash flows. On May 27, 1998, COM/Energy selected affiliates of Southern Energy New England, L.L.C., an affiliate of The Southern Company of Atlanta, Georgia, to buy substantially all of its non-nuclear electric generating assets. As a result of construction-related adjustments at the closing on December 30, 1998, the final amount of proceeds from the sale was approximately $454 million. These facilities represented 984 MW of electric capacity and had a book value of $74 million. The plants 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 Elec- tric; five diesel generators (13.8 MW) in Oak Bluffs and West Tisbury on the island of Martha's Vineyard that are owned by the Company, and a 1.4 percent joint-ownership interest (8.9 MW) in Wyman Unit No. 4 located in Yarmouth, ME, also owned by the Company. The Company continues to evaluate bids related to its purchased power contracts. On July 31, 1998, a divestiture filing was submitted to the FERC and the DTE that requested approval of the sale of the generating assets to Southern Energy and further proposed (subject to completion of the sale) that the current 10 percent rate reduction increase, effective January 1, 1999. On October 30, 1998, the DTE approved COM/Energy's sale of assets to Southern Energy. However, at that time, the DTE deferred ruling on the allocation of the net proceeds from the sale of Canal Units 1 and 2 between the Company and Cambridge Electric and on the rate of return to be paid to customers on the net proceeds from the sale over an eleven-year period. The FERC approved the sale on November 12, 1998. On December 23, 1998, the DTE approved COM/Energy's proposal to establish a special purpose affiliate, Energy Investment Services, Inc. (EIS), that will administer the above-book value net proceeds from the sale of the Canal units with the goal of preserving capital and maximizing earnings for the benefit of retail customers. EIS will credit the proceeds and any return earned to the accounts of the Company and Cambridge Electric, resulting in a reduction in the transition costs to be billed to customers. In addition, COM/Energy agreed to pursue the buyout of above-market purchased power contracts, including the Pilgrim nuclear unit in which the Company has an 11% entitle- ment. This transaction is expected to occur in the second quarter of 1999. On December 23, 1998, the DTE approved the divestiture filing that was submitted to the FERC and the DTE on July 31, 1998 that requested approval of <PAGE 8> COMMONWEALTH ELECTRIC COMPANY the sale of the generating assets to Southern Energy and further proposed (subject to completion of the sale which occurred on December 30, 1998) that the 10 percent rate reduction increase, effective January 1, 1999, to approxi- mately 12 percent. In addition, the Company proposed to increase the retail price of standard offer service, starting January 1, 1999, from 2.8 cents per kilowatthour (kwh) to 3.5 cents. At the same time, the transition charge for the Company's customers declined from 4.08 cents per kwh to 3.159 cents. These changes 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 Company's cost deferrals associated with the pricing of standard offer service. (b) Unbundled Rates As a result of electric 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. Unbundled delivery rates are composed of a customer charge (to collect metering and billing costs), a distribution charge (to collect the costs of delivering electricity), a transition charge (to collect past costs for investments in generating plants and costs related to power contracts), a transmission charge (to collect the cost of moving the electricity over high voltage lines from a generating plant), an energy conservation charge (to collect costs for demand-side management programs) and a renewable energy charge (to collect the cost to support the development and promotion of renewable energy projects). Electricity supply services provided by the Company include optional standard offer service and default service. Standard offer service is the electricity that is supplied by the local distribution company (such as the Company) until a competitive power supplier is chosen by the customer. It is designed as a seven-year transitional service to give the customer time to learn about competitive power suppliers. The price of standard offer service will increase over time. Default service is supplied by the local distribution company when a customer is not receiving power from either standard offer service or a competitive power supplier. The market price for default service will fluctuate based on the average market price for power. Amounts collected through these various charges will be reconciled to actual expenditures on an on-going basis. Prior to the implementation of industry restructuring on March 1, 1998, the Company had a Fuel Charge rate schedule that generally allowed for current recovery, from retail customers, of fuel used in electric production, pur- chased power and transmission costs. This schedule required a quarterly computation and DTE approval of a Fuel Charge decimal based upon forecasts of fuel, purchased power, transmission costs and billed unit sales for each period. To the extent that collections under the rate schedule did not match actual costs for that period, an appropriate adjustment was reflected in the calculation of the next subsequent calendar quarter decimal. This rate schedule is no longer in effect. Also prior to March 1, 1998, the Company collected a portion of capacity- related purchased power costs associated with certain long-term power arrange- ments through base rates. The recovery mechanism for these costs used a per kwh factor that was calculated using historical (test-period) capacity costs and unit sales. This factor was then applied to current monthly kwh sales. <PAGE 9> COMMONWEALTH ELECTRIC COMPANY When current period capacity costs and/or unit sales varied from test-period levels, the Company experienced a revenue excess or shortfall that had a significant impact on net income. However, as part of the settlement agree- ments approved by the DTE in May 1995, the Company was allowed to defer these costs (within certain limits) which neutralized their sometimes volatile effect on net income. The Company also had separately stated Conservation Charge rate schedules that allowed for current recovery, from retail custom- ers, of conservation and load management costs. These rate schedules are no longer in effect. (c) Conservation and Load Management Programs The Company has implemented a variety of cost-effective C&LM programs that are designed to reduce future energy use by its customers. In 1993, the DTE began allowing the recovery by the Company of its "lost base revenues" from customers as a rate component employed by the DTE to encourage effective implementation of C&LM programs. These and other C&LM costs were recovered through a Conservation Charge decimal. The KWH savings that were realized as a result of the successful implementation of C&LM programs served as the basis for determining lost base revenues. Pursuant to the Restructuring Act, the Company has agreed to mandatory charges per KWH to fund energy efficiency and demand-side management activities. (d) Retail Choice Pilot Program Prior to March 1, 1998, the date retail choice was available for all customers, the Company had designed a program to allow a limited number of customers the opportunity to possibly reduce their electric bills while the Company learned more about real-time pricing and the administrative require- ments associated with open-market competition. Through the program, the Company developed internal procedures for billing and allocating the costs for providing an alternative supply to its retail customers, and developed methods for educating customers regarding retail choice. The program was available to the 18 commercial and industrial customers that took service under one of the Company's economic development rates. This program was discontinued on February 28, 1998. (e) Transmission Rate Matters The Company provides power supply and transmission services to its FERC- jurisdictional wholesale customers and requires FERC approval to change its wholesale rates. On March 29, 1995, the FERC issued two notices of proposed rulemaking concerning open access transmission and stranded costs. The FERC's notices proposed to remove impediments to competition in the wholesale bulk power mar- ketplace and to bring more efficient, lower-cost power to electric consumers. On April 24, 1996, the FERC issued Order No. 888, a set of three interre- lated rules resolving the above rulemakings. The FERC required all public utilities that own, control or operate transmission facilities in interstate commerce to have on file wholesale Open Access Transmission Tariffs (OATTs) that conform to the FERC pro-forma tariff contained in Order No. 888. On July 9, 1996, the Company filed OATTs that conform to the FERC's pro-forma tariffs. On November 13, 1996, the FERC accepted the non-rate terms and conditions of <PAGE 10> COMMONWEALTH ELECTRIC COMPANY these tariffs effective July 9, 1996, subject to a revision of one section dealing with the scheduling of services. On January 21, 1997, the Company filed revised OATTs to be consistent with the most recently filed NEPOOL OATT. On March 4, 1997, the FERC issued Order No. 888-A which required revisions to the tariffs filed in compliance with Order No. 888. The Company filed its revised OATTs on July 14, 1997. On July 31, 1997, the FERC issued an order on the July 9, 1996 filings, approving the rates, pending the outcome of any outstanding proceedings. On November 25, 1997, the FERC issued Order No. 888-B requiring minor changes that did not require an additional filing. On September 31, 1998, following the filing of NEPOOL's revised OATT, the Company filed revised OATTs for consistency with NEPOOL. Currently, the Company is awaiting decisions by FERC on the OATTs filed after 1996. (f) Energy Rate Matters On December 31, 1996, the Company filed market-based power sales tariffs with the FERC with the intent to make wholesale power sales at fully negotiat- ed rates. FERC approved the tariffs on February 27, 1997. In addition, the Company requested and received authorization to participate as brokers in the sale and purchase of electricity. Competition The Company continues to develop and implement strategies that deal with the restructured utility industry. The planned merger with BEC Energy and the sale of its generating assets are actions that are indicative of the Company's commitment to seeking competitive advantages and other benefits by taking advantage of its strengths. For a more detailed discussion of the pending merger with BEC Energy, refer to the "Merger with BEC Energy" section of Management's Discussion and Analysis of Results of Operations filed under Item 7 of this report. Prior to March 1, 1998, the Company developed and implemented strategies that dealt with the increasingly competitive environment then facing the electric utility business. The inherently high cost of providing energy services in the Northeast had placed the region at a competitive disadvantage as more customers began to explore alternative energy supply options. Pursuant to preliminary electric industry restructuring rules issued in late 1996, the DTE proposed to implement programs under which utility and non- utility generators could sell electricity to customers of other utilities without regard to previously closed franchise service areas. The DTE initial- ly began an inquiry into incentive ratemaking in 1994. The Company had developed innovative pricing mechanisms designed to retain existing customers, add new retail and wholesale customers and expand beyond current markets. On February 6, 1997, due to the dramatically changing nature of the electric and gas industries, COM/Energy announced the consolidation of management personnel of the Company and affiliates Cambridge Electric, Commonwealth Gas Company and COM/Energy Services Company effective on that date. The Company and these affiliates continue to operate under their existing company names. The consolidation process for these companies involved the merging of similar functions and activities to eliminate duplica- tion in order to create the most efficient and cost-effective operation <PAGE 11> COMMONWEALTH ELECTRIC COMPANY possible. As part of this consolidation effort, the Company initiated a voluntary Personnel Reduction Program that ultimately resulted in a decrease of 127 regular employees (15.1%) in 1997. In 1998, there was a further net reduction of 21 regular employees. Some of the more specific details of the innovative measures taken in response to competition include the following: Rate Stabilization Plan The Company implemented a FC rate settlement on April 1, 1994, amended in May 1995, that stabilized its quarterly FC rate during the years 1994 through 1996 at 6.5 cents per KWH and no greater than 6.7 cents per KWH during 1997. However, the Company decided to maintain a FC of 6.5 cents per KWH in 1997 and defer, for later recovery, the difference between the 6.5 and 6.7 cents per KWH FC. The rate stabilization was achieved through the use of a cost deferral mechanism that was sponsored jointly by the Company and the Massachusetts Attorney General and approved by the DTE. The deferred costs are reflected as a regulatory asset to be recovered, with carrying charges, over the subsequent six-year period beginning in 1998. The deferred amount, excluding carrying charges, was restricted to a maximum of $40 million during the settlement period (1994 through 1997) and was further limited to an annual amount of $16 million. The deferred balance at December 31, 1998 amounted to $26.7 million. Effective March 1, 1998, this and other regulatory assets are reflected in rates charged to customers to be recovered over the next 11 years pursuant to the restructuring legislation discussed previously. The rate stabilization mechanism was part of a long-term plan to control the Company's retail rates. This plan helped to eliminate the disincentive for economic development resulting from a volatile and unpredictable FC rate. The stabilized FC rate had enabled current and prospective customers to better plan their business and personal finances in a more efficient and effective manner. In addition to the Massachusetts Attorney General, this proposal was widely supported by various business and customer groups and other political interests. Economic Development Realizing a healthy regional economy benefits not only businesses but all area residents, the Company actively encourages economic growth by working in partnership with communities and businesses, providing resources and incentives to help the region's economy. The Company also funded the development of a business plan that focused on improving infrastructure, regulation, access to capital, marketing and promotion, cooperation and leadership on Cape Cod. In an effort to foster industrial development in its service area, the Company began offering an Economic Development Rate in October 1991 to new or existing industrial customers with an electric demand of 500 kilowatts or more and meet specific financial and other criteria. The number of commercial and industrial customers that participated in this special rate were 21 and 31 at December 31, 1997 and 1996, respectively. The rate was available for a six- year term that terminated on March 1, 1998. The Company also offered a Vacant Space Rate that was available to qualifying small commercial and industrial customers who established loads in previously unoccupied building space. These rates were terminated on March 1, 1998 as retail choice was introduced to provide consumers with the opportunity to purchase power from a competitive supplier or remain with the Company through standard offer service. However, <PAGE 12> COMMONWEALTH ELECTRIC COMPANY the DTE encourages the Company to pursue all necessary solutions to meet the energy needs of their customers and will support properly designed economic development rates that can be provided to customers by distribution companies in the future. Construction and Financing Information concerning the Company's financing and construction programs is contained in Note 3(a) of Notes to Financial Statements filed under Item 8 of this report. Employees The total number of full-time employees for the Company declined 2.9% in 1998 to 695 from 716 employees at year-end 1997. The Company has 485 employ- ees (69.8%) who are represented by the Brotherhood of Utility Workers of New England, Inc. under three separate collective bargaining units with agreements that expire October 31, 2001, September 30, 2002 and April 30, 2003. Employee relations have generally been satisfactory. Item 2. Properties The principal properties of the Company consist of an integrated system of transmission and distribution lines, substations, an office building in the Town of Wareham, MA and other structures such as garages and service build- ings. The Company sold to an affiliate of The Southern Company of Atlanta, GA, two diesel plants with a combined capability of 13.8 MW located on the island of Martha's Vineyard that were used for standby and emergency purposes. Also sold was the Company's 1.4% joint-ownership interest in Central Maine Power Company's Wyman Unit 4 with an entitlement of 8.8 MW. At December 31, 1998, the electric transmission and distribution system consisted of 5,768 pole miles of overhead lines, 3,803 cable miles of under- ground line, 139 substations and 339,925 active customer meters.

Management's Discussion and Analysis of Results of Operations The following is a discussion of certain significant factors that have affected operating revenues, expenses and net income during the periods included in the accompanying Statements of Income and is presented to facili- tate an understanding of the results of operations. This discussion should be read in conjunction with Item 1 of this report and the Notes to Financial Statements filed under Item 8 of this report. A summary of the period to period changes in the principal items included in the accompanying Statements of Income for the years ended December 31, 1998 and 1997 and unit sales for these periods is shown below: Years Ended Years Ended December 31, December 31, 1998 and 1997 1997 and 1996 Increase (Decrease) (Dollars in thousands) Electric Operating Revenues $(46,450) (9.9)% $ 17,669 3.9% Operating Expenses - Electricity purchased for resale and fuel (41,695) (13.7) 14,619 5.0 Transmission 1,661 31.5 1,230 30.5 Other operation (3,114) (3.9) 7,065 9.8 Maintenance (1,413) (11.0) 22 0.2 Depreciation 455 2.6 513 3.0 Taxes - Federal and state income (1,242) (11.9) (2,553) (19.7) Local property and other 62 0.7 612 7.5 (45,286) (10.3) 21,508 5.2 Operating Income (1,164) (3.6) (3,839) (10.6) Other Income 270 131.1 271 56.8 Income Before Interest Charges (894) (2.8) (3,568) (9.9) Interest Charges 920 6.0 (886) (5.4) Net Income $ (1,814) (10.7) $ (2,682) (13.7) Unit Sales (Megawatthours or MWH) Retail (17,129) (0.5) 88,213 2.6 Wholesale 282,177 24.0 325,054 38.1 Total unit sales 265,048 5.6 413,267 9.6 <PAGE 15> COMMONWEALTH ELECTRIC COMPANY Unit Sales and Customers The following is a summary of unit sales and customers for the periods indicated: Years Ended December 31, 1998 1997 1996 % % Unit Sales (MWH): Change Change Residential 1,652,797 (0.9) 1,668,193 1.4 1,645,011 Commercial 1,473,761 0.2 1,470,179 3.7 1,417,790 Industrial 363,559 (1.3) 368,509 3.5 356,009 Streetlighting 15,815 (2.3) 16,180 0.9 16,039 Total retail 3,505,932 (0.5) 3,523,061 2.6 3,434,849 Wholesale 1,460,170 24.0 1,177,993 38.1 852,938 Total 4,966,102 5.6 4,701,054 9.6 4,287,787 Customers - 12 Month Average: Residential (a) 285,659 1.3 281,927 1.2 278,653 Commercial (a) 39,978 2.4 39,044 1.1 38,609 Industrial 292 (1.4) 296 (1.0) 299 Streetlighting 1,106 2.3 1,081 (1.7) 1,100 Total 327,035 1.5 322,348 1.2 318,661 (a) Includes seasonal customers of 45,537 in 1998, 46,147 in 1997 and 46,862 in 1996. Service is considered to be "seasonal" when the kilowatthours used in the billing months ending between June 1 and September 30 exceed the kilowatthours used in the preceding eight months. Total unit sales for 1998 and 1997 increased primarily as a result of greater sales to Independent System Operator (ISO) - New England (the agency that operates a centralized facility to ensure reliability of service and dispatch of economically available generating units throughout New England). The Company's residential customer segment provides approximately 47% of its total retail sales and approximately 8% of those customers rely on electricity for space heating. The Company expects that its retail unit sales compound annual growth rate over the next five years will average 2.1%. Operating Revenues Operating revenues for 1998 declined $46.5 million (9.9%) despite higher unit sales, primarily due to the 10 percent rate reduction (further discussed below), and a net decrease in electricity purchased for resale, fuel and transmission charges of $40 million (12.9%). The decline in these costs reflects a cost deferral of $35.3 million in conjunction with the Company's restructuring plan as approved by the Massachusetts Department of Telecommuni- cations and Energy (DTE). As a result of electric 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. 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 <PAGE 16> COMMONWEALTH ELECTRIC COMPANY 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. For addition- al information concerning electric industry restructuring, refer to the "Rates, Regulation and Legislation" section filed under Item 1 of this report. Operating revenues for 1997 increased $17.7 million (3.9%) due to a greater level of wholesale sales ($9.7 million) reflecting the changing capacity needs of ISO - New England. Fluctuations in the level of wholesale electric sales have no impact on net income. Also contributing to the increase in revenues were higher retail unit sales ($4.2 million), higher revenues related to the recovery of electricity purchased for resale, trans- mission and fuel to retail customers ($4.6 million), and the recovery of costs associated with conservation and load management programs (C&LM) ($1 million). Offsetting these factors was the absence of a $4 million refund associated with a 1996 power contract settlement agreement. Wholesale revenues have increased in each of the past three years and amounted to $27.9 million, $27.8 million and $18.2 million in 1998, 1997 and 1996, respectively. Pursuant to a 1995 settlement agreement with the DTE that limited the Company's return on equity through 1997, revenues in 1997 and 1996 reflect a customer refund of $1.7 million and $1.8 million, respectively. As a result of a DTE mandated recovery mechanism implemented in July 1991 for capacity-related costs associated with certain long-term purchased power contracts, the Company had experienced a revenue excess or shortfall when unit sales and/or the costs recoverable in base rates varied from test-period levels. This issue, which had a significant impact on net income, was addressed in a settlement agreement approved by the DTE in May 1995. The Company was able to defer these costs (within certain limits) to neutralize the sometimes volatile effect on net income. For the first two months of 1998 and in 1997 and 1996, there was an overcollection of approximately $764,000, $1.9 million and $400,000, respectively, that reduced the deferred balance in the fuel charge stabilization account pursuant to the May 1995 settlement agreement. There was no net income impact in these periods. The deferred balance at December 31, 1998 amounted to $26.7 million. Effective March 1, 1998, this regulatory asset is reflected in rates charged to customers to be recovered over the next 11 years pursuant to the restructuring legislation. Electricity Purchased for Resale, Transmission and Fuel To satisfy demand requirements and provide required reserve capacity, the Company purchased power on a long and short-term basis through entitlements pursuant to power contracts with other New England and Canadian utilities, Qualifying Facilities and other non-utility generators through a competitive bidding process that was regulated by the DTE. The Company supplemented these sources with its own generating capacity that was sold on December 30, 1998. The cost of electricity purchased for resale, fuel and transmission constituted 63.5%, 65.8% and 64.8% in 1998, 1997 and 1996, respectively, of electric operating revenues. These costs reflect higher unit sales in each <PAGE 17> COMMONWEALTH ELECTRIC COMPANY succeeding year and in addition, a cost deferral of $35.3 million in 1998 that resulted primarily from providing the required 10% rate reduction for retail customers. Other Operating Expenses Other operation declined $3.1 million (3.9%) in 1998 and primarily reflects the absence of a one-time charge ($8.4 million) related to a person- nel reduction program (PRP) initiated in the second quarter of 1997. Also contributing to the decrease were labor savings realized from the aforemen- tioned PRP ($2.4 million), a reduction in the provision for bad debts ($1.5 million), and a reduction in insurance and employee benefits costs ($2.1 million). The impact of these factors was offset, in part, by higher costs relating to the outsourcing of the information technology, telecommunications and network services function ($6.1 million) including costs associated with Year 2000 compliance, higher costs related to conservation and load management programs ($2.9 million) and costs related to supporting the industry restruc- turing referendum question on the November 1998 ballot ($735,000). Other operation in 1997 increased $7.1 million (9.8%) due to the aforemen- tioned PRP charge, an increase in the provision for bad debts ($750,000) that reflected higher reserve requirements, and an increase in costs associated with C&LM programs ($2.3 million). The impact of these factors was offset, in part, by lower pension costs ($1.5 million) and lower operating costs ($2.9 million) that resulted, in part, from the PRP. Included in other operation is amortization of certain prior-period deferred costs, including costs associated with C&LM programs, purchased power, certain postretirement benefits, and litigation costs related to the Pilgrim nuclear power unit that in total amounted to $6 million, $6.4 million and $4.8 million in 1998, 1997 and 1996, respectively. In 1998, maintenance declined $1.4 million (11%) due to the absence of storm damage costs related to an April 1997 blizzard ($1.8 million). Mainte- nance was virtually unchanged in 1997 but included costs associated with reduced maintenance primarily on transmission and distribution facilities and the aforementioned blizzard that was offset by the absence of storm damage costs that resulted from Hurricane Edouard ($2.1 million) in 1996. Depreciation expense increased $455,000 and $500,000 in 1998 and 1997, respectively, and reflected additions to property, plant and equipment. Federal and state income taxes declined $1.2 million (11.9%) in 1998 and $2.6 million (19.7%) in 1997 due mainly to the change in pretax income. Local property and other taxes in 1998 and in 1997 increased primarily due to higher property tax assessments and rates. Payroll and other taxes declined $371,000 in 1998 due to the PRP and increased by $117,000 in 1997. Other Income (Expense) Other income increased in 1998 due to interest accrued on the deferred transition costs associated with electric industry restructuring ($1.3 million) effective March 1, 1998. <PAGE 18> COMMONWEALTH ELECTRIC COMPANY Other income increased in 1997 primarily due to the absence of a $300,000 settlement paid in 1996 by the Company related to costs associated with energy conservation management services provided by an outside vendor. Interest Charges Total interest charges increased in 1998 reflecting a greater level of short-term borrowings, offset somewhat by slightly lower short-term rates and scheduled sinking fund payments on long-term debt. Total interest charges declined in 1997 reflecting scheduled sinking fund payments and lower interest on potential federal and state income tax defi- ciencies ($361,000). Interest on short-term borrowings also declined due to a lower average level of borrowings despite a slightly higher average interest rate (5.8%) for the year. 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 Company's business and financial results could cause actual results to differ materially from those stated in the forward-looking state- ments or projected amounts. Those factors include developments in the legislative, regulatory and competitive environment, certain environmental matters, demands for capital expenditures and the availability of cash from various sources. Merger with BEC Energy The electric utility industry has continued to change in response to legislative and regulatory mandates that are aimed at lowering prices for energy by creating a more competitive marketplace. These pressures have resulted in an increasing trend in the electric industry to seek competitive advantages and other benefits through business combinations. On December 5, 1998, the Parent and BEC Energy (BEC), headquartered in Boston, Massachusetts, entered into an Agreement and Plan of Merger (the Merger Agreement). Pursuant to the Merger Agreement, COM/Energy and BEC will be merged into a new holding company to be known as NSTAR. The merger is expected to occur shortly after the satisfaction of certain conditions, including the receipt of certain regulatory approvals including that of the DTE. The regulatory approval process is expected to be completed during the second half of 1999. The merger will create an energy delivery company serving approximately 1.3 million customers located entirely within Massachusetts, including more than one million electric customers in 81 communities and 240,000 gas custom- ers in 51 communities. Shareholder votes on the merger will be held as part of each of COM/Energy's and BEC's annual shareholder meetings scheduled for the second quarter of 1999. The Merger Agreement may be terminated under certain circumstances, including by any party if the merger is not consummated by December 5, 1999, subject to an automatic extension of six months if the requisite regulatory approvals have not yet been obtained by such date. The <PAGE 19> COMMONWEALTH ELECTRIC COMPANY merger will be accounted for using the purchase method of accounting. Upon effectiveness of the merger, Thomas J. May, BEC's current Chairman, President and Chief Executive Officer (CEO), will become the Chairman and CEO of NSTAR. Russell D. Wright, COM/Energy's current President and CEO, will become the President and Chief Operating Officer of NSTAR and will serve on NSTAR's board of directors. Also, upon effectiveness of the merger, NSTAR's board of directors will consist of COM/Energy's and BEC's current trustees. Provisions of Statement of Financial Accounting Standards No. 71 As described in Note 2(b) of the Notes to Financial Statements, the Company follows the provisions of Statement of Financial Accounting Standards (SFAS) No. 71, "Accounting for the Effects of Certain Types of Regulation." In the event the Company is somehow unable to meet the criteria for following SFAS No. 71, the accounting impact would be an extraordinary, non-cash charge to operations in an amount that could be material. Conditions that could give rise to the discontinuance of SFAS No. 71 include: 1) increasing competition restricting the Company'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. The Company monitors these criteria to ensure that 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 Company believes that its utility operations, excluding generation-related assets, remain subject to SFAS No. 71 and its regulatory assets, including those related to electric generation, remain probable of future recovery. As a result of electric industry restructuring, the Company discontinued application of accounting principles applied to its electric generation facilities effective March 1, 1998. The Company will not be required to write off any of its generation-related assets, including regulatory assets. These assets will be retained on the Company's Balance Sheets because the legisla- tion and the DTE's plan for a restructured electric industry specifically provide for their recovery through the non-bypassable transition charge. 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. COM/Energy has been involved in Year 2000 compliancy since 1996. COM/Energy, on a coordinated basis and with the assistance of RCG Informa- tion Technologies and other consultants, is addressing the Year 2000 issue. COM/Energy has followed a five-phase process in its Year 2000 compliance efforts, as follows: Awareness (through a series of internal announcements to employees and through contacts with vendors); Inventory (all computers, applications and embedded systems that could potentially be affected by the Year 2000 problem); Assessment (all applications or components and the impact on overall business operations and a plan to correct deficiencies and the cost to do so); Remediation (the modification, upgrade or replacement of deficient hardware and software applications and infrastructure modifications); and <PAGE 20> COMMONWEALTH ELECTRIC COMPANY Testing (a detailed, comprehensive testing program for the modified critical component, system or software that involves the planning, execution and analysis of results). COM/Energy's inventory phase required an assessment of all date sensitive information and transaction processing computer systems and determined that approximately 90% of its software systems needed some modifications or replacement. Plans were developed and are being implemented to correct and test all affected systems, with priorities assigned based on the importance of the activity. COM/Energy has identified the software and hardware installa- tions that are necessary. All installations are expected to be completed and tested by mid-1999. COM/Energy 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. COM/Energy is approximately 86% complete in its efforts to resolve non-compliance with Year 2000 requirements related to its non-information technology systems. COM/Energy anticipates that these systems will be updated or replaced as necessary and tested by mid- 1999. At present, the remediation phase for information technology as it applies to hardware and non-technology issues is scheduled for completion by June 1, 1999. The testing phase for Year 2000 compliance is approximately 70% complete and is scheduled to be concluded by June 30, 1999. All other phases are complete. Modifying and testing COM/Energy's information and transaction processing systems from 1996 through 2000 is currently expected to cost approximately $7 million, including approximately $900,000 incurred through 1997 and $3.1 million spent in 1998. Approximately $3 million is expected to be spent in 1999 and 2000. Year 2000 costs have been expensed as incurred and will continue to be funded from operations. In addition to its internal efforts, COM/Energy has initiated formal communications with its significant suppliers to determine the extent to which COM/Energy may be vulnerable to its suppliers' failure to correct their own Year 2000 issues. As of February 1, 1999, COM/Energy has received responses from approximately 75% of those entities contacted, and nearly all have indicated that they are or will be Year 2000 compliant. Failure of COM/Energy's significant suppliers to address Year 2000 issues could have a material adverse effect on COM/Energy'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 COM/Energy. Contact with significant vendors is continuing and inadequate or marginal responses are being pursued by COM/Energy. COM/Energy is prepared to replace certain suppliers or to initiate other contingency plans should these vendors not respond to COM/Energy's satisfaction by July 1, 1999. 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 COM/Energy's ability to acquire energy and its ability to serve its customers <PAGE 21> COMMONWEALTH ELECTRIC COMPANY as effectively as they are now being served. COM/Energy 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 ele- ments. COM/Energy has started its contingency planning for critical operational areas that might be effected by the Year 2000 issue if compliance by COM/Energy is delayed. COM/Energy 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 June 30, 1999, although in certain cases, especially infrastructure failures, there may be no practical alternative course of action available to COM/Energy. COM/Energy 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 COM/Energy believes its efforts to address the Year 2000 issue will allow it to be successful in avoiding any material adverse effect on COM/Energy'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 distrib- ute 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, COM/Energy 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 COM/Energy could include, among other things, business disruption, increased costs, loss of business and other similar risks. The foregoing discussion regarding Year 2000 project timing, effective- ness, 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 COM/Energy's ability to respond to unforeseen Year 2000 complications. Environmental Matters The Company is subject to laws and regulations administered by federal, state and local authorities relating to the quality of the environment. These laws and regulations affect, among other things, the siting and operation of electric generating and transmission facilities and can require the installa- tion of expensive air and water pollution control equipment. These regula- tions have had an impact on the Company's operations in the past and will continue to have an impact on future operations, capital costs and construc- tion schedules of major facilities. On January 1, 1997, COM/Energy adopted the provisions of Statement of Position (SOP) 96-1, "Environmental Remediation Liabilities." SOP 96-1 <PAGE 22> COMMONWEALTH ELECTRIC COMPANY provides authoritative guidance for recognition, measurement, display and disclosure of environmental remediation liabilities in financial statements. The Company has recorded environmental remediation liabilities net of amounts paid of $849,000 at December 31, 1998. The adoption of SOP 96-1 did not have a material adverse effect on COM/Energy's results of operations or financial position. New Accounting Principles In June 1998, the Financial Accounting Standards Board issued 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 con- tracts) 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 adoption of SFAS No. 133 is not expected to have a material impact on the Company's results of operations or financial condition. Item 7A. Quantitative and Qualitative Disclosures About Market Risk Although the Company has material commodity purchase contracts and financial instruments (debt), these instruments are not subject to market risk. The Company has a rate making mechanism which allows for the recovery of fuel costs from customers. The fuel adjustment mechanism allows the Company to pass all costs related to the purchase of commodities to the customer, thereby insulating the Company from market risk. Similarly, any change in the fair market value of the Company's prudently incurred debt obligations realized by the Company would be borne by customers through future rates. Item 8.

Changes in and Disagreements With Accountants on Accounting and Financial Disclosure None. <PAGE 23> COMMONWEALTH ELECTRIC COMPANY Item 8. Financial Statements and Supplementary Data REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Board of Directors of Commonwealth Electric Company: We have audited the accompanying balance sheets of COMMONWEALTH ELECTRIC COMPANY (a Massachusetts corporation and wholly-owned subsidiary of Common- wealth Energy System) as of December 31, 1998 and 1997, and the related statements of income, retained earnings and cash flows for each of the three years in the period ended December 31, 1998. These financial statements and the schedules referred to below are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedules based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Commonwealth Electric Company as of December 31, 1998 and 1997, and the results of its operations and its cash flows for each of the three years in the period ended Decem- ber 31, 1998, in conformity with generally accepted accounting principles. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The schedules listed in the index to financial statements and schedules are presented for purposes of complying with the Securities and Exchange Commission's rules and are not part of the basic financial statements. These schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, fairly state, in all material respects, the financial data required to be set forth therein in relation to the basic financial statements taken as a whole.

The Parent, together with its subsidiaries, is collectively referred to as "COM/Energy." The Parent 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 and several non-regulated companies. The Company's operations have been involved in the production, distribution and sale of electricity to 327,000 customers (including 45,500 seasonal) in 40 communities located in south- eastern Massachusetts, including Cape Cod and the island of Martha's Vineyard, having an approximate year-round population of 549,000 and a large influx of summer residents. In December 1998, the Parent signed an Agreement and Plan of Merger with BEC Energy, the parent company of Boston Edison Company, that will create an energy delivery company, that includes the Company, serving approximately 1.3 million customers located entirely within Massachusetts including more than one million electric customers in 81 communities and 240,000 gas customers in 51 communities. The Company has 695 regular employees including 485 (70%) represented by three collective bargaining units covered by separate contracts with expira- tion dates ranging from October 2001 through April 2003. Employee relations have generally been satisfactory. In response to the significant changes that have taken place in the utility industry, the Company sold all of its non-nuclear generating assets in 1998 to focus on the transmission and distribution of energy and related services. (2) Significant Accounting Policies (a) Principles of Accounting The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain prior year amounts are reclassified from time to time to conform with the presentation used in the current year's financial statements. (b) Regulatory Assets and Liabilities The Company is 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 Company 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." The Company has established various regula- <PAGE 31> COMMONWEALTH ELECTRIC COMPANY tory 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 Company 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 Company'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 Company believes that its regulatory assets, including those related to generation, are probable of future recovery. As a result of electric industry restructuring, the Company discontinued application of accounting principles applied to its investment in electric generation facilities effective March 1, 1998. The Company will not be required to write off any of its generation-related assets, including regula- tory assets. These assets will be retained on the Company's 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. The principal regulatory assets included in deferred charges were as follows: 1998 1997 (Dollars in thousands) Transition costs $ 38,622 $ - Power contract buy-out 15,717 17,609 Fuel charge stabilization 26,682 29,655 Postretirement benefit costs 12,269 12,271 Yankee Atomic unrecovered plant and decommissioning costs 2,042 3,436 Pilgrim nuclear plant litigation costs 5,417 5,929 Other 1,146 1,212 $101,895 $70,112 The regulatory liabilities, reflected in the accompanying Balance Sheets were as follows: 1998 1997 (Dollars in thousands) Regulatory liability related to sale of generating assets $293,186 $ - Demand-side management deferral 2,274 - Excess Seabrook-related deferred income taxes 319 698 Other deferred income taxes 1,782 1,875 Excess replacement power refunds 132 246 $297,693 $ 2,819 The regulatory liability of $293.2 million was established pursuant to the Company's divestiture filing that was approved by the DTE in which the Company agreed to use its share of the net proceeds from affiliate Canal Electric <PAGE 32> COMMONWEALTH ELECTRIC COMPANY Company's (Canal Electric) sale of generation assets and the sale of its own generating assets to reduce transition costs that are billed to its retail electric customers over the next several years as a result of electric industry restructuring. COM/Energy established Energy Investment Services, Inc. as the vehicle to invest the net proceeds from the sale of Canal Electric's generating assets. These proceeds will be invested in a conserva- tive portfolio of securities that is designed to maintain principal and earn a reasonable return. Both the principal amount and income earned will be used to reduce the transition costs that would otherwise be billed to customers of the Company and Cambridge Electric. The Company's share of the net proceeds from the sale of Canal Electric's generating assets has been classified as a long-term receivable - affiliate on the accompanying Balance Sheets. The Company's regulatory assets, including the costs associated with an existing power contract with the Yankee Atomic nuclear power plant that was shut down permanently (see Note 3(d)), and all of its regulatory liabilities are reflected in rates charged to customers. Regulatory assets are to be recovered over the next 11 years pursuant to the legislation discussed below. In November 1997, the Commonwealth of Massachusetts enacted a comprehen- sive electric utility industry restructuring bill. On November 19, 1997, the Company, together with affiliates Cambridge Electric Light Company (Cambridge Electric) and Canal Electric, filed a restructuring plan with the DTE. The plan, approved by the DTE on February 27, 1998, provides that the Company and Cambridge Electric, 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 liabili- ties related to the generation portion of the electric business. (c) Transactions with Affiliates Transactions between the Company and other COM/Energy companies include purchases and sales of electricity, including purchases from Canal Electric, an affiliated wholesale electric generating company. Other Canal transactions include costs relating to the abandonment of Seabrook 2 and the recovery of a portion of Seabrook 1 pre-commercial operation costs. In addition, payments for management, accounting, data processing and other services are made to an affiliate, COM/Energy Services Company. Transactions with other COM/Energy companies are subject to review by the DTE. <PAGE 33> COMMONWEALTH ELECTRIC COMPANY The Company's operating expenses include the following major intercompany transactions for the periods indicated: Purchased Power Purchased Power and Transmission Period Ended Purchased Power and Transmission From Canal December 31, Canal Units Seabrook 1 as Agent (Dollars in thousands) 1998 $56,269 $29,403 $ 2,605 1997 61,087 31,417 6,524 1996 40,733 31,848 9,096 The costs for the Canal and Seabrook 1 units are included in the long-term obligation table listed in Note 3(b). The Company sold electricity to other affiliates, primarily station service for Canal, totaling $1,026,000, $1,290,000 and $1,453,000 in 1998, 1997 and 1996, respectively. (d) Operating Revenues Customers are billed for their use of electricity on a cycle basis throughout the month. To reflect revenues in the proper period, the estimated amount of unbilled sales revenue is recorded each month. The Company is generally permitted to bill customers for costs associated with purchased power and transmission, fuel used in electric production and conservation and load management (C&LM) costs. The amount of such costs incurred by the Company but not yet reflected in customers' bills is recorded as unbilled revenues. (e) Depreciation Depreciation is provided using the straight-line method at rates intended to amortize the original cost and the estimated cost of removal less salvage of properties over their estimated economic lives. The average composite depreciation rates were 3.33% in 1998 and 3.32% in 1997 and 1996. (f) Maintenance Expenditures for repairs of property and replacement and renewal of items determined to be less than units of property are charged to maintenance expense. Additions, replacements and renewals of property considered to be units of property are charged to the appropriate plant accounts. Upon retirement, accumulated depreciation is charged with the original cost of property units and the cost of removal less salvage. (g) Allowance for Funds Used During Construction Under applicable rate-making practices, the Company is permitted to include an allowance for funds used during construction (AFUDC) as an element of its depreciable property costs. This allowance is based on the amount of construction work in progress that is not included in the rate base on which the Company earns a return. An amount equal to the AFUDC capitalized in the current period is reflected in other interest charges in the Company's Statements of Income and amounted to $163,000, $145,000 and $98,000 in 1998, 1997 and 1996, respectively. <PAGE 34> COMMONWEALTH ELECTRIC COMPANY While AFUDC does not provide funds currently, these amounts are recover- able in revenues over the service life of the constructed property. The amount of AFUDC recorded was at a weighted average rate of 5.75% in 1998 and 6.25% in 1997 and 1996. (3) Commitments and Contingencies (a) Financing and Construction Programs The Company is engaged in a continuous construction program presently estimated at $135.8 million for the five-year period 1999 through 2003. Of that amount, $30.5 million is estimated for 1999. The program is subject to periodic review and revision because of factors such as changes in business conditions, rates of customer growth, effects of inflation, maintenance of reliable and safe service, equipment delivery schedules, licensing delays, availability and cost of capital and environmental factors. The Company expects to finance these expenditures on an interim basis with internally generated funds and short-term borrowings that are ultimately expected to be repaid with the proceeds from sales of long-term debt and equity securities. (b) Power Contracts The Company has long-term contracts to purchase capacity from various generating facilities. Generally, these contracts are for fixed periods and require payment of a demand charge for the capacity entitlement and an energy charge to cover the cost of fuel. In addition, the Company pays its share of decommissioning expenses under its nuclear contracts. Information relative to these long-term contracts is as follows: Range of Contract Expiration Entitlement Cost Dates % MW 1998 1997 1996 (Dollars in thousands) Type of Unit Natural Gas 2008-2017 (a) 184.1 $107,118 $114,773 $111,007 Oil 2002 (b) 266.0 54,957 58,187 36,060 Nuclear 2004-2026 (c) 106.1 66,775 68,381 68,716 Waste-to-energy 2015 100 67.0 44,423 43,038 39,622 Hydro 2014-2023 100 23.9 11,359 10,952 12,537 Total 647.1 $284,632 $295,331 $267,942 (a) Includes contracts to purchase power from various non-utility genera- ting facilities with capacity entitlements ranging from 11.1% to 100%. (b) Includes entitlements in Canal Unit 1 (20%) and Canal Unit 2 (40%). On May 27, 1998, COM/Energy selected affiliates of Southern Energy New England, L.L.C., an affiliate of The Southern Company of Atlanta, Georgia, to buy substantially all of its non-nuclear electric generat- ing assets, including Canal Units 1 and 2. Under long-term contracts, the Company's entitlement in Unit 1 is 111.1 MW. However, the Company continues to purchase energy and capacity under a series of long-term contracts, and this entitlement includes its share of one-quarter of the capacity and energy of Canal Unit 1, which is now purchased from the new plant owner, Southern Energy Canal, L.L.C. (Southern). The Company's cost of service agreement with Canal Electric for its share <PAGE 35> COMMONWEALTH ELECTRIC COMPANY of the capacity and energy purchased from Canal Unit 2 was terminated as part of the generating asset sale on December 30, 1998. The former Unit 2 agreement was replaced by a new agreement under which Southern sells energy and capacity to the Company to support its customer load obligation, at fixed rates that are equivalent to the Company's standard offer (wholesale) rates. (c) Includes entitlements in Seabrook 1 (2.8%) and Pilgrim (11% through 2001, 8.8% in 2002, and 5.5% for 2003 through 2004). The Pilgrim unit is expected to be sold in 1999 to Entergy Nuclear Generating Company. In conjunction with the sale, the Company has reached an agreement to buy out of this contract, but will continue to buy power on a declin- ing basis through 2004. Costs pursuant to these contracts are included in electricity purchased for resale in the Company's Statements of Income and are recoverable in revenues. The costs associated with these power contract obligations are a significant component of the Company's stranded costs that are being recovered through a transition charge pursuant to DTE approval. The estimated aggregate obligations for capacity under the long-term purchased power contracts and a life-of-the-unit contract from the Seabrook 1 unit in effect for the five years subsequent to 1998 is as follows: Long-Term Purchased Power (Dollars in thousands) 1999 $286,019 2000 284,006 2001 340,921 2002 329,744 2003 289,270 (c) Environmental Matters The Company is subject to laws and regulations administered by federal, state and local authorities relating to the quality of the environment. These laws and regulations affect, among other things, the siting and operation of electric generating and transmission facilities and can require the installa- tion of expensive air and water pollution control equipment. These regula- tions have had an impact on the Company's operations in the past and will continue to have an impact on future operations, capital costs and construc- tion schedules of major transmission and distribution facilities. (4) Income Taxes For financial reporting purposes, the Company provides federal and state income taxes on a separate-return basis. However, for federal income tax purposes, the Company's taxable income and deductions are included in the consolidated income tax return of the Parent and it makes tax payments or receives refunds on the basis of its tax attributes in the tax return in accordance with applicable regulations. <PAGE 36> COMMONWEALTH ELECTRIC COMPANY The following is a summary of the Company's provisions for income taxes for the years ended December 31, 1998, 1997 and 1996: 1998 1997 1996 (Dollars in thousands) Federal Current $ (3,824) $ 5,852 $10,818 Deferred 11,843 3,174 374 Investment tax credits, net (472) (430) (433) 7,547 8,596 10,759 State Current (833) 1,254 1,997 Deferred 2,442 548 195 1,609 1,802 2,192 $ 9,156 $10,398 $12,951 The significant change in the current and deferred provisions for income taxes in 1998 reflects the current tax related to the sale of the company's non-nuclear generating assets and the related deferred tax benefit. Deferred tax liabilities and assets are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect in the year in which the differences are expected to reverse. Accumulated deferred income taxes consisted of the following in 1998 and 1997: 1998 1997 (Dollars in thousands) Liabilities Property-related $ 55,342 $54,605 Transition costs 14,778 - Fuel charge stabilization 11,300 12,241 Power contract buy-out 6,135 6,853 All other 9,447 8,647 97,002 82,346 Assets Deferred tax asset 114,340 - Investment tax credit 4,046 4,322 All other 9,454 9,120 127,840 13,442 Accumulated deferred income taxes (deferred tax asset), net $(30,838) $68,904 The net deferred tax asset for 1998 is included in other deferred charges in the accompanying Balance Sheets. The net year-end deferred income tax liability for 1997 includes a current deferred tax liability of $18,621,000 that is included in accrued income taxes. <PAGE 37> COMMONWEALTH ELECTRIC COMPANY The total income tax provision set forth previously represents 38% in 1998 and 1997 and 40% in 1996 of income before such taxes. The following table reconciles the statutory federal income tax rate to these percentages: 1998 1997 1996 (Dollars in thousands) Federal statutory rate 35% 35% 35% Federal income tax expense at statutory levels $ 8,493 $ 9,562 $11,395 Increase (Decrease) from statutory levels: State tax net of federal tax benefit 1,046 1,171 1,425 Tax versus book depreciation 198 105 103 Amortization of investment tax credits (472) (430) (433) Reversals of capitalized expenses (76) (63) (64) Additional reserves for tax deficiencies - - 431 Other (33) 53 94 $ 9,156 $10,398 $12,951 Effective federal income tax rate 38% 38% 40% (5) Employee Benefit Plans (a) Pension The Company has a noncontributory pension plan covering substantially all regular employees who have attained the age of 21 and have completed a year of service. Pension benefits are based on an employee's years of service and compensation. The Company makes monthly contributions to the plan consistent with the funding requirements of the Employee Retirement Income Security Act of 1974. The following tables set forth the change in the pension benefit obliga- tion and plan assets as well as the plan's funded status reconciled to the amount included in the financial statements: 1998 1997 (Dollars in thousands) Change in benefit obligation Obligation at beginning of year $ 184,290 $ 157,604 Service cost 2,954 3,245 Interest cost 12,702 11,306 Actuarial loss 17,760 22,150 Benefits paid (11,539) (10,015) Obligation at end of year $ 206,167 $ 184,290 1998 1997 (Dollars in thousands) Change in plan assets Fair value of plan assets at beginning of year $ 177,112 $ 155,650 Actual return on plan assets 13,692 27,678 Employer contributions 2,469 3,799 Transfers to affiliated companies (74) - Benefits paid (11,539) (10,015) Fair value of plan assets at end of year $ 181,660 $ 177,112 <PAGE 38> COMMONWEALTH ELECTRIC COMPANY 1998 1997 (Dollars in thousands) Funded status $ (24,507) $ (7,178) Unrecognized transition obligation 1,930 2,574 Unrecognized prior service cost 4,030 4,594 Unrecognized net actuarial (gain) loss 11,120 (6,560) Prepaid (accrued) benefit cost $ (7,427) $ (6,570) Weighted-average assumptions as of December 31 were as follows: 1998 1997 Discount rate 6.50% 7.00% Expected return on plan assets 9.00 8.75 Rate of increase in future compensation 3.75 3.75 Plan assets consist primarily of fixed-income and equity securities. Fluctuations in the fair market value of plan assets will affect pension expense in future years. Components of net periodic pension cost were as follows: 1998 1997 1996 (Dollars in thousands) Service cost $ 2,954 $ 3,245 $ 3,405 Interest cost 12,702 11,306 11,300 Expected return on plan assets (13,537) (12,055) (11,065) Amortization of transition obligation 643 643 643 Amortization of prior service cost 562 563 563 Total 3,324 3,702 4,846 Transfer from (to) affiliated companies, net 76 (231) (191) Less: Amounts capitalized and deferred 1,454 1,714 1,369 Net periodic pension cost $ 1,946 $ 1,757 $ 3,286 The net periodic pension cost reflects the use of the projected unit credit method which is also the actuarial cost method used in determining future funding of the plan. The Company, in accordance with current ratemaking, is deferring the difference between the pension contribution that is reflected in base rates, and pension expense. (b) Other Postretirement Benefits Certain employees are eligible for postretirement benefits if they meet specific requirements. These benefits could include health and life insurance coverage and reimbursement of Medicare Part B premiums. Under certain circumstances, eligible employees are required to make contributions for postretirement benefits. To fund its postretirement benefits, the Company makes contributions to various voluntary employees' beneficiary association trusts that were estab- lished pursuant to section 501(c)(9) of the Internal Revenue Code (the Code). The Company also makes contributions to a subaccount of its pension plan pursuant to section 401(h) of the Code to fund a portion of its postretirement benefit obligation. <PAGE 39> COMMONWEALTH ELECTRIC COMPANY The following tables set forth the change in the postretirement benefit obligation and plan assets as well as the plan's funded status reconciled to the amount included in the financial statements: 1998 1997 (Dollars in thousands) Change in benefit obligation Obligation at beginning of year $ 68,697 $ 58,928 Service cost 1,046 980 Interest cost 4,751 4,355 Actuarial loss 7,060 6,863 Participant contributions 47 28 Benefits paid (3,705) (2,457) Obligation at end of year $ 77,896 $ 68,697 1998 1997 (Dollars in thousands) Change in plan assets Fair value of plan assets at beginning of year $ 30,229 $ 22,635 Actual return on plan assets 2,092 4,369 Employer contributions 5,418 5,654 Participant contributions 47 28 Benefits paid (3,705) (2,457) Fair value of plan assets at end of year $ 34,080 $ 30,229 Funded status $ (43,816) $ (38,468) Unrecognized transition obligation 33,832 36,250 Unrecognized net actuarial loss 9,984 2,218 Prepaid (accrued) benefit cost $ - $ - Weighted-average assumptions as of December 31 were as follows: 1998 1997 Discount rate 6.50% 7.00% Expected return on plan assets 9.00 8.75 Rate of increase in future compensation 3.75 3.75 For measurement purposes, a 6.50% annual rate of increase in the per capita cost of covered medical claims was assumed for 1999. The rates were assumed to decrease gradually to 4.5% for 2007 and remain at that level thereafter. Dental claims and Medicare Part B premiums are expected to increase at 4.5% and 3.1%, respectively. Plan assets consist primarily of fixed-income and equity securities. Fluctuations in the fair market value of plan assets will affect the periodic postretirement benefit cost in future years. <PAGE 40> COMMONWEALTH ELECTRIC COMPANY Components of net periodic postretirement benefit cost were as follows: 1998 1997 1996 (Dollars in thousands) Service cost $ 1,046 $ 980 $ 1,132 Interest cost 4,751 4,355 4,382 Expected return on plan assets (2,796) (2,098) (1,564) Amortization of transition obligation 2,417 2,417 2,417 Total 5,418 5,654 6,367 Transfers from affiliates, net (211) (645) (500) Add: Net amortization of deferrals 858 858 858 Less: Amounts capitalized and deferred 807 936 1,022 Net periodic postretirement benefit cost $ 5,258 $ 4,931 $ 5,703 Assumed healthcare cost trend rates have a significant effect on the amounts reported for health care plans. A one-percentage point change in assumed healthcare cost trend rates would have the following effects: One-Percentage-Point Increase Decrease (Dollars in thousands) Effect on total of service and interest cost components $ 903 $ (723) Effect on postretirement benefit obligation $10,217 $ (9,550) Effective May 1, 1995 the DTE approved a settlement proposal sponsored jointly by the Company and the Attorney General of Massachusetts that allows the Company to fully recover costs relating to postretirement benefits and to amortize its $8.6 million deferred balance over a ten-year period. At December 31, 1998 and 1997, the Company's deferral amounted to approximately $5.4 million and $6.3 million, respectively. (c) Savings Plan The Company has an Employees Savings Plan that provides for Company contributions equal to contributions by eligible employees of up to four percent of each employee's compensation rate and up to five percent for those employees no longer eligible for postretirement health benefits. The total Company contribution was $1,435,000 in 1998, $1,672,000 in 1997, and $1,788,000 in 1996. <PAGE 41> COMMONWEALTH ELECTRIC COMPANY (6) Long-Term Debt and Interim Financing (a) Long-Term Debt Maturities and Retirements Long-term debt outstanding, exclusive of current maturities, current sinking fund requirements and related premiums, is as follows: Original Balance December 31, Issue 1998 1997 (Dollars in thousands) 15-Year Term Loan, 9.30%, due 2002 $30,000 $ 30,000 $ 30,000 25-Year Term Loan, 9.37%, due 2012 20,000 13,684 14,737 10-Year Notes, 7.43%, due 2003 15,000 15,000 15,000 15-Year Notes, 9.50%, due 2004 15,000 5,000 7,500 15-Year Notes, 7.70%, due 2008 10,000 10,000 10,000 18-Year Notes, 9.55%, due 2007 10,000 10,000 10,000 20-Year Notes, 7.98%, due 2013 25,000 25,000 25,000 25-Year Notes, 9.53%, due 2014 10,000 10,000 10,000 30-Year Notes, 9.60%, due 2019 10,000 10,000 10,000 30-Year Notes, 8.47%, due 2023 15,000 15,000 15,000 $143,684 $147,237 The Company, under favorable conditions, may purchase its outstanding notes in advance; however, an early payment premium may be incurred. Certain of these agreements require the Company to make periodic sinking fund payments for retirement of outstanding long-term debt. The required sinking fund payments for the five years subsequent to December 31, 1998 are as follows: Sinking Fund Maturing Year Payments Debt Issues Total (Dollars in thousands) 1999 $3,553 $ - $ 3,553 2000 3,553 - 3,553 2001 3,481 - 3,481 2002 3,481 30,000 33,481 2003 3,481 15,000 18,481 (b) Notes Payable to Banks The Company and other COM/Energy companies maintain both committed and uncommitted lines of credit for the short-term financing of their construction programs and other corporate purposes. As of December 31, 1998, COM/Energy had $122 million of committed lines of credit that will expire at varying intervals in 1999. These lines are normally renewed upon expiration and require annual fees of up to .1875% of the individual line. At December 31, 1998, the uncommitted lines of credit totaled $10 million. Interest rates on the outstanding borrowings generally are at an adjusted money market rate and averaged 5.7% and 5.8% in 1998 and 1997, respectively. At December 31, 1998, the Company had no notes payable to banks. Notes payable to banks totaled $14.9 million at December 31, 1997. <PAGE 42> COMMONWEALTH ELECTRIC COMPANY (c) Advances from Affiliates The Company is a member of the COM/Energy Money Pool (the Pool), an arrangement among the subsidiaries of the Parent, whereby short-term cash surpluses are used to help meet the short-term borrowing needs of the utility subsidiaries. In general, lenders to the Pool receive a higher rate of return than they otherwise would on such investments, while borrowers pay a lower interest rate than those available from banks. Interest rates on the out- standing borrowings are based on the monthly average rate the Company would otherwise have to pay banks, less one-half the difference between that rate and the monthly average U.S. Treasury Bill weekly auction rate. The borrow- ings are for a period of less than one year and are payable upon demand. Rates on these borrowings averaged 5.3% and 5.4% in 1998 and 1997, respective- ly. Notes payable to the Pool totaled $40,350,000 and $5,315,000 at December 31, 1998 and 1997, respectively. The Company had no notes payable to the Parent at December 31, 1998 or December 31, 1997. However, this source of financing may be utilized by the Company and notes are written for a term of up to 11 months and 29 days. Interest is at the prime rate and is adjusted for changes in that rate during the term of the notes. The rate averaged 8.3% and 8.5% in 1998 and 1997, respectively. (d) Disclosures About Fair Value of Financial Instruments The fair value of certain financial instruments included in the accompany- ing Balance Sheets as of December 31, 1998 and 1997 are as follows: 1998 1997 (Dollars in thousands) Carrying Fair Carrying Fair Value Value Value Value Long-term debt $147,204 $171,667 $150,745 $171,787 The carrying amount of cash, notes payable to banks and advances to/from affiliates approximates the fair value because of the short maturity of these financial instruments. The estimated fair value of long-term debt is based on quoted market prices of the same or similar issues or on the current rates offered for debt with the same remaining maturity. The fair values shown above do not purport to represent the amounts at which those obligations would be settled. (7) Dividend Restriction At December 31, 1998, there were no retained earnings restricted against the payment of cash dividends pursuant to the Company's term loans and note agreements securing long-term debt. (8) Lease Obligations The Company leases equipment and office space under arrangements that are classified as operating leases. These lease agreements are for terms of one <PAGE 43> COMMONWEALTH ELECTRIC COMPANY year or longer. Leases currently in effect contain no provisions that prohibit the Company from entering into future lease agreements or obliga- tions. Future minimum lease payments, by period and in the aggregate, of non-can- celable operating leases consisted of the following at December 31, 1998: Operating Leases (Dollars in thousands) 1999 $ 2,857 2000 1,384 2001 794 2002 794 2003 450 Beyond 2003 1,840 Total future minimum lease payments $ 8,119 Total rent expense for all operating leases, except those with terms of a month or less, amounted to $2,718,000 in 1998, $3,174,000 in 1997 and $2,814,000 in 1996. There were no contingent rentals and no sublease rentals for the years 1998, 1997 and 1996. <PAGE 44> COMMONWEALTH ELECTRIC COMPANY PART IV. Item 14.
