BUSINESS THE COMPANY Yankee Energy System, Inc. ("Yankee Energy" or the "Company"), is a public utility holding company incorporated in Connecticut in 1989. The Company is primarily engaged in the retail distribution of natural gas through its wholly- owned subsidiary, Yankee Gas Services Company ("Yankee Gas"), a Connecticut public service company. Yankee Gas serves approximately 183,000 residential, commercial and industrial customers in 68 cities and towns in Connecticut. The Company is exempt from registration under the Public Utility Holding Company Act of 1935. The Company has four additional wholly-owned operating subsidiaries which support the Company's core natural gas distribution business or allow the Company to position itself in the market place as a provider of a full range of energy-related mechanical services to commercial, industrial and institutional customers. Yankee Energy Services Company ("YESCo") provides comprehensive building automation services, including engineering, installing, and maintaining building control systems through its YESCo Controls Division and comprehensive heating ventilation and air-conditioning ("HVAC"), boiler and refrigeration equipment services and installation through its YESCo Mechanical Services Division. During fiscal 1998, YESCo's Power Division also provided expertise related to the production of thermal and/or electric power. R.M. Services, Inc., directly and under contract with Dun and Bradstreet Receivables Management Services, provides residential collection services for companies throughout the United States, and Yankee Energy Financial Services Company ("Yankee Financial") provides a full range of equipment and home improvement financing services through various programs, such as the Hometown Energy Loan Program. Finally, NorConn Properties, Inc. ("NorConn"), owns selected system real estate and leases it to Yankee Gas. After completing a recent review of the various operating functions of YESCo, management of the Company has decided to focus the efforts of YESCo on its Controls and HVAC lines of business and to significantly reduce its cost structure. As a result, the Company intends to dispose of the assets of the YESCo Power Division in fiscal 1999. In addition, the Company has restructured its HVAC business, including the consolidation of four locations into one operating center, the elimination of redundant administrative and operating positions and better focusing its business both geographically by ceasing all non-Connecticut activities and operationally by discontinuing its HVAC equipment sales operation. GAS MARKETS AND CUSTOMERS General. Yankee Gas operates the largest natural gas distribution system in Connecticut as measured by number of customers and size of service territory. Total throughput (sales and transportation) for fiscal 1998 was 47.1 billion cubic feet ("Bcf"). In fiscal 1998, total gas operating revenues were comprised of the following: 47% residential; 26% commercial; 18% industrial; and the remaining 9% other. Yankee Gas provides firm gas sales service to customers who require a continuous gas supply throughout the year, such as residential customers who rely on gas for their heating, hot water, and cooking needs. Yankee Gas also provides interruptible gas sales service to certain commercial and industrial customers that have the capability to switch from natural gas to an alternative fuel on short notice. Yankee Gas can interrupt service to these customers during peak demand periods. Yankee Gas offers firm and interruptible transportation services to customers who purchase gas from sources other than Yankee Gas. In addition, Yankee Gas performs gas exchanges and capacity releases to marketers to reduce its overall gas expense. Firm Sales. In fiscal 1998, total firm gas sales of 26 Bcf accounted for approximately 84% of total throughput and approximately 84% of the Company's total operating revenues. Firm gas sales, particularly sales for residential space heating, are highly seasonal. In fiscal 1998, about 65% of total firm sales occurred in the five months from November through March. The following tables set forth certain information with respect to firm sales in fiscal 1998. FISCAL 1998 FIRM SALES Volumes as Average Number Volumes a Percent of of Customers in Bcf Revenues Firm Sales -------------- ------- -------- ------------ Residential 160,917 11.9 $134,359,345 46 Commercial 17,762 6.9 66,726,188 26 Industrial 1,728 7.3 36,051,517 28 ------- ---- ------------ --- 180,407 26.1 $237,137,050 100% Interruptible Sales. In fiscal 1998, total interruptible gas sales of 4.9 Bcf accounted for approximately 16% of total throughput and approximately 7% of the Company's total operating revenues. The price charged for interruptible sales service is a market price based on the cost of the customer's alternative fuel, which is usually oil. Interruptible sales depend upon the availability of gas supplies and, generally, have provided lower margins than firm sales. Yankee Gas has authorization from the Connecticut Department of Public Utility Control (the "DPUC") to engage in flexible pricing to meet market prices for alternative fuels available to interruptible customers. The following table sets forth certain information with respect to interruptible sales in fiscal 1998. FISCAL 1998 INTERRUPTIBLE SALES Average Number Volumes of Customers in Bcf Revenues -------------- ------- -------- Commercial and Industrial 241 4.9 $20,066,670 Transportation Services. Yankee Gas offers firm and interruptible transportation service to its industrial and commercial customers. In fiscal 1998, total transportation sales accounted for approximately 8% of the Company's total operating revenues. These transportation services permit customers who desire to purchase gas from sources other than Yankee Gas to do so, provided they have made all the necessary arrangements with the transmission pipelines to deliver their gas to the Yankee Gas distribution system. Industrial and commercial customers can purchase gas directly from producers and suppliers and contract for transportation services rather than purchase gas solely from the local distribution system. Generally, interruptible transportation service is highly sensitive to alternative fuel prices as well as to the availability of interstate pipeline capacity into the region. Under existing tariff structures, the financial condition of the Company is unaffected by customers electing to use transportation service in lieu of making gas purchases from Yankee Gas. Market Expansion Strategy. The Company is near completion of a customer and market segmentation study that the Company believes will provide an in-depth analysis of customer use of the Company's products and services and will be used to identify additional sales opportunities. As this study is completed, marketing information about current customers and new opportunities will direct the Company's efforts to expand its distribution service. These efforts are expected to focus on increasing the number of residential households using natural gas, increasing the uses of natural gas by existing Yankee Gas customers, and increasing the overall number of both large and small customers through expansion of Yankee Gas' distribution system within its service territory. In the residential market, Yankee Gas focuses marketing efforts on households along Yankee Gas' existing mains because they present opportunities to increase gas sales with little or no capital investment. In the commercial and industrial markets, the Company seeks to expand gas sales by increasing sales to existing customers for both traditional and innovative uses, such as infrared heating, cooling and electric generation. The Company also emphasizes attracting new commercial and industrial customers within its service territory. The emergence of natural gas vehicles creates a potential new market for the natural gas industry. The establishment of natural gas vehicle fueling stations, however, is essential to the development of this market. Yankee Gas, in cooperation with various oil companies and gasoline retailers, has opened retail public natural gas vehicle refueling stations in Windsor Locks, Norwalk, and Meriden, Connecticut. Yankee Gas operates two refueling stations for its own fleet of approximately 110 natural gas vehicles. GAS SUPPLY In 1992, the Federal Energy Regulatory Commission ("the FERC") issued Order No. 636, which required natural gas pipeline companies to separate or "unbundle" their services. Prior to the issuance of Order No. 636, natural gas pipeline companies sold pipeline services, such as gas purchasing, storage and transportation, as a package. In 1993, the interstate pipeline companies that provided natural gas to Yankee Gas complied with Order No. 636. As a result, Yankee Gas executed contracts with interstate pipeline companies for services to transport gas from production and underground storage areas to Yankee Gas' service territory to replace the traditional merchant services previously provided by the pipeline companies. Yankee Gas concurrently replaced the gas supply traditionally obtained from the pipeline companies' merchant services with firm purchases directly from producers and/or marketing companies. The FERC continues to regulate the rates charged by interstate pipeline companies for transportation and storage of natural gas, but does not regulate the price of natural gas purchased by the Company from producers and marketing companies. Interstate pipelines delivered over 99.9 percent of Yankee Gas' 1998 fiscal year requirements to its distribution system. Interstate pipeline capacity enabled Yankee Gas to meet its firm customers' requirements with pipeline supplies for more than 99.9 percent of the year. The following table sets forth sources of fiscal 1998 gas supply (including purchases for storage injections): Percent of Source Total Supply ------ ------------ Alberta Northeast Gas, Limited 54.76 Other Canadian Supplies 21.72 Domestic Supply 23.51 Other (Peaking) 0.01 ------ Total 100.00% Yankee Gas is entitled to purchase 68,460 thousand cubic feet ("Mcf") per day of gas, or about 25 Bcf annually, from Canadian gas suppliers. The sales contracts between Yankee Gas and its Canadian suppliers expire in 2003 and 2006. Most of the gas purchased from the Canadian suppliers is delivered in the United States by the Iroquois Gas Transmission System, L.P. ("Iroquois"). The transportation contract between Yankee Gas and Iroquois expires in 2011. During fiscal 1998, Yankee Gas' largest Canadian supplier was Alberta Northeast Gas, Limited ("ANE"). ANE is an entity formed by several utilities in the Northeast to aggregate the purchase of gas from Western Canada and to facilitate its sale to local gas distribution company ("LDC") owners at the United States-Canadian border. Yankee Gas held a 15.9 percent equity interest in ANE until July 1, 1998 at which time Yankee Gas reduced its equity interest to 5.3 percent. Yankee Gas also holds pipeline transportation and storage service contracts with Tennessee Gas Pipeline Company ("Tennessee"), Algonquin Gas Transmission Company ("Algonquin"), Texas Eastern Transmission Corporation ("Texas Eastern"), CNG Transmission Corporation ("CNG Transmission"), Transcontinental Gas Pipe Line Company ("Transco"), and National Fuel Gas Supply Corporation ("National Fuel") as summarized below: TRANSPORTATION SERVICE CONTRACTS: Annual Transport Pipeline Quantity Expiration -------- -------- ---------- Tennessee 27.7 Bcf 2000-2017 Algonquin 39.6 Bcf 1999-2014 Texas Eastern 38.2 Bcf 2000-2014 CNG Transmission 2.7 Bcf 2003-2012 Transco 0.63 Bcf 2008 National Fuel 2.63 Bcf 1999-2003 STORAGE SERVICE CONTRACTS: Annual Storage Pipeline Quantity Expiration -------- -------- ---------- Tennessee 1.9 Bcf 2000 Texas Eastern 1.7 Bcf 2012-2013 CNG Transmission 1.4 Bcf 2003-2012 National Fuel 0.8 Bcf 1999 Although several contracts are scheduled to terminate during 1999 and 2000, they may be continued on a year to year basis by mutual consent of the parties. Yankee Gas has terminated its National Fuel storage and 2 Bcf of its National Fuel transportation effective March 31, 1999. Yankee Gas has also terminated 1.8 Bcf of Algonquin transportation effective October 31, 1999. Yankee Gas has entered comprehensive gas supply agreements with Engage Energy US, L.P. ("Engage") and TransCanada Gas Services Inc. ("TransCanada") which optimize portions of its supply portfolio. Specifically, the Engage agreement optimizes gas supply delivered to Yankee Gas by Algonquin and expires in 2000 while the TransCanada agreement optimizes gas supply delivered by Tennessee and expires in 2001. Under these agreements, the supplier delivers Yankee Gas' full fuel requirements on the respective pipeline while optimizing the value of the supply and associated transportation and storage during off-peak conditions. The agreements also provide Yankee Gas with enhanced supply flexibility. Yankee Gas does not have sufficient capacity entitlements on the interstate pipelines to serve its firm customers with pipeline-delivered gas at all times. During the winter, therefore, whenever daily firm demand exceeds the amount of gas delivered by the pipelines, service to interruptible customers is curtailed. Yankee Gas supplements pipeline gas with a propane-air mixture produced at facilities within Yankee Gas' service territory and with contracted peaking gas supplies. In fiscal 1998, these gas supplies comprised less than 1 percent of Yankee Gas' total supply. REGULATION AND RATES Federal Regulation. Although Yankee Gas is not subject to FERC jurisdiction, the FERC does regulate the interstate pipelines serving Yankee Gas' service territory. Yankee Gas, therefore, is directly and substantially affected by the FERC's policies and actions. Accordingly, Yankee Gas closely follows and, when appropriate, participates in proceedings before the FERC. Connecticut Regulation. Yankee Gas is subject to regulation by the DPUC, which, among other things, has jurisdiction over rates, accounting procedures, certain dispositions of property and plant, mergers and consolidations, issuances of securities, standards of service, management efficiency and construction and operation of distribution, production and storage facilities. The DPUC may, after a special public hearing, order an interim rate decrease if it finds that Yankee Gas' return on equity exceeds a reasonable rate of return and rates are more than just, reasonable and adequate as determined by the DPUC. The DPUC also is empowered to grant an interim rate increase under compelling circumstances. Yankee Gas sells gas to its retail customers under rate schedules filed with and approved by the DPUC. Firm sales rates are subject to monthly adjustments pursuant to a Purchased Gas Adjustment ("PGA") clause approved by the DPUC. The PGA passes through to customers most changes in the cost of gas purchased by Yankee Gas. These adjustments are designed to collect or refund differences between actual purchased gas costs and the costs included in Yankee Gas' base rates. In 1997, the DPUC conducted a review of the Connecticut LDCs' PGA mechanism to determine if any changes were warranted. The most significant change approved by the DPUC was the authorization for LDCs to pass on to customers the costs of the Connecticut Gross Earnings Tax related to PGA revenues. Yankee Gas' rate order, effective for service rendered on and after October 1, 1992, allowed a return on equity (ROE) of 12.43 percent and provided for favorable accounting treatment for environmental cleanup costs, post-retirement benefits and certain other major items. On August 25, 1996, Yankee Gas filed an application with the DPUC for a Financial and Operation Review (Review) of Yankee Gas. This Review was required under Connecticut law because Yankee Gas had not undergone a rate proceeding within the four years preceding the 1996 application. The DPUC issued a decision on July 9, 1997, which called for a reduction of Yankee Gas' ROE from 12.43 percent to 11.15 percent. The DPUC believed that lower interest rates and allowed rates of return for other Connecticut utilities justified a lower ROE for Yankee Gas. On October 1, 1997, the DPUC approved an amendment to the settlement agreement between Yankee Gas and the Connecticut Office of Consumer Counsel that, among other things, required Yankee Gas to credit $3.2 million to firm sales customers through the PGA during fiscal 1998. As of September 30, 1998, the entire $3.2 million had been accrued and approximately $2.9 million had been credited to firm sales customers. The remaining $0.3 million has been included in the Company's annual deferred fuel calculation and credited to firm sales customers beginning in October 1998. Pursuant to the settlement agreement with the Connecticut Office of Consumer Counsel, Yankee Gas agreed not to apply for a rate increase prior to October 1, 2000, except in the event of certain circumstances that would have a significant adverse effect on Yankee Gas' financial condition. If such an event arises, Yankee Gas has the option to apply to the DPUC for a rate increase or to retain up to 80% of any off system sales margin and excess interruptible margin. FERC Order No. 636. In implementing Order No. 636, the FERC recognized that the restructuring of the pipelines' traditional services would cause pipelines to incur transition costs in several areas. The FERC has permitted certain transition costs to be recovered by the pipeline companies from their customers. In July 1994, the DPUC issued an order permitting the recovery of transition costs billed by pipelines under Order No. 636 through various mechanisms authorized by the DPUC. Through September 30, 1998, Yankee Gas has paid approximately $20.5 million of transition costs and an additional $2.5 million are anticipated. To date, Yankee Gas has collected $46.3 million through a combination of credits received from pipeline refunds, capacity release agreements, deferred gas costs credits, off system sales margins and excess interruptible margins. The DPUC approved the settlement agreement in January 1996 and an amendment thereto in October 1997 between Yankee Gas and the Connecticut Office of Consumer Counsel that permits Yankee Gas to retain over-collected transition cost credits to offset certain deferred regulatory assets. As of September 30, 1998, excess collections of approximately $25.8 million were applied against the deferred regulatory assets specified in the agreement. In January 1996, the DPUC, in response to Order No. 636, authorized the Connecticut LDCs to offer unbundled firm transportation rates to its commercial and industrial customers. The DPUC's decision permits Yankee Gas to offer a variety of service options to its commercial and industrial firm transportation customers. Yankee Gas implemented new firm transportation rates and services in April 1996. In October, 1998, the DPUC issued a decision making a number of modifications to the commercial and industrial firm transportation program. These modifications, which will become effective on January 1, 1999, are designed to simplify and improve the program based on the initial firm transportation experience. As of September 30, 1998, Yankee Gas had approximately 3,100 customers under firm transportation service. The conversion by existing customers to transportation service will result in decreased revenues for Yankee Gas, as that portion of revenues representing gas costs will be borne directly by these customers who will purchase their own gas directly. Yankee Gas, however, does not expect customer conversions to transportation services to affect its net income because the cost of gas has traditionally been a pass through item with no income impact. The DPUC's decision did not address Yankee Gas' revenue requirement. Order No. 636 also authorizes LDCs to make off system sales or to release firm pipeline capacity and Yankee Gas has engaged in these activities to maximize revenues and for effective gas supply planning. ENERGY SERVICES On May 6, 1998, Yankee Gas filed an application with the DPUC to discontinue on-demand, non-contract service work. Following the issuance of a draft decision requiring Yankee Gas to continue to provide this type of service work, Yankee Gas withdrew its application. Yankee Gas intends to petition the DPUC for an increase in the applicable service rates. This decision will not have a material impact on the Company's financial condition or results of operations. The Company has refocused its mission to diversify into energy-related businesses. This has resulted in a restructuring of YESCo, which included consolidation of facilities and elimination of certain positions of the HVAC division and a decision to close down the Power Division and sell its Power Projects. The elimination of redundant administrative and operating positions better focuses the business both geographically by ceasing all non-Connecticut activities and operationally by discontinuing HVAC equipment sales operation. YESCo provides comprehensive building automation services, including engineering, installing, and maintaining building control systems through its YESCo Controls Division and comprehensive HVAC, boiler and refrigeration equipment services and installation through its YESCo Mechanical Services Division. During fiscal 1998, YESCo's Power Division also provided expertise related to the production of thermal and/or electric power. COMPETITION Yankee Gas' principal competitors are unregulated fuel-oil retailers and regulated electric utilities. Natural gas competes with oil and electricity in many commercial and industrial applications and in residential space and water heating, clothes drying and cooking. Demand for natural gas is affected by the marketing and pricing of competing sources of energy. Yankee Gas may also face competition from other LDCs. In the past, LDCs did not directly compete with other LDCs for retail customers because the territories they serve are fixed by franchise. However, since 1993, LDCs began marketing efforts within the service territory of other LDCs under blanket certificates granted by the FERC. These certificates allow gas to be sold, but not necessarily delivered, in the service territory of another LDC. Within Yankee Gas' service territory, Yankee makes available its transportation services to move other parties' gas through its distribution system. The Company believes that deregulation of the sale of natural gas has created an opportunity for its commercial and industrial customers to achieve savings on the purchase price of natural gas by helping its customers lower the purchase price of natural gas. The Company believes it will achieve more throughput through its distribution system. This volume increase is expected to result in higher transportation margin. The Company further believes that increasing competition in gas marketing will result in growth in the Company's gas distribution business. There can be no assurance, however, that such deregulation and increased competition in gas marketing will have a beneficial effect on the Company's results of operations. Federal regulation also permits customers within Yankee Gas' distribution system to connect directly with transmission pipelines and bypass Yankee Gas' distribution system. A Connecticut statute currently prohibits an interstate pipeline from bypassing a LDC without the DPUC's prior approval. The Company believes that Yankee Gas is successfully addressing the threat of bypass by its industrial customers by understanding what services they need and executing market-competitive gas service agreements. There is, however, a potential risk of loss of revenues from bypass of Yankee Gas' distribution system. One of Yankee Gas' largest customers during fiscal 1998 was the Foxwoods Hotel and Casino (Foxwoods), operated by the Mashantucket Pequot Indian Tribe, (the "Pequots"). The City of Norwich, Connecticut has completed construction of a pipeline extending from its distribution system to Foxwoods and began service to Foxwoods on December 1, 1998. Norwich, pursuant to its agreement with the Pequots, will become the sole provider of gas transportation service to the Pequots. The Company is currently negotiating with the Pequots to recover its investment in facilities previously constructed to serve them. ENVIRONMENTAL MATTERS The Company is subject to federal and state environmental regulation of its operations and properties and has an ongoing monitoring program to review compliance with existing environmental standards. Such regulation may result in future environmental liabilities that may include significant expenses to remove, contain or remediate contamination, including coal tar deposits, caused by operations of former gas manufacturing plants by Yankee Gas' predecessor companies prior to the introduction of pipeline gas into the region during the 1950s. Those predecessor companies disposed of the coal tar in accordance with the standard operating practices of the time. Fourteen sites containing coal tar became the property of Yankee Gas at the time of divestiture from its former parent company. Yankee Gas has reported the results of environmental studies conducted at these sites to the Connecticut Department of Environmental Protection ("DEP"). Eight of the fourteen sites are currently listed on the Connecticut Inventory of Hazardous Waste Sites. Inclusion of a site on this list is an indication that remediation may be required in the future. Significant remediation efforts have been conducted at three of these properties. In addition, the Company has developed a cost estimate for the remaining sites based on various factors including the probability of clean-up. The Company recorded a liability of $35 million in fiscal year 1993 for future environmental cleanup. Recovery of remediation costs has been specifically allowed by Yankee Gas' 1992 rate case decision. Currently, $325,000 is allowed annually in rates and an additional $2.5 million annually may be deferred. If costs are expected to exceed $2.5 million on an annual basis, Yankee Gas is required to petition the DPUC for review and additional authorization. The DPUC has stated that "to the extent that coal tar remediation expenses are prudently incurred, they should be allowed as proper operating expenses." The Company expects to finance environmental remediation expenditures through a combination of internally generated funds, short-term debt and through funds received from certain of its insurance carriers in settlement of certain claims for actual or potential contamination at certain sites that may give rise to environmental liabilities, which funds have totaled $9.6 million as of September 30, 1998. Management does not believe that the Company's environmental expenditures will have a material adverse effect on its operations, liquidity or financial position, based on known facts and existing laws and regulations and the anticipated period over which expenditures will be made. FRANCHISES Yankee Gas and its predecessors in interest have held valid franchises to sell gas in the areas in which Yankee Gas supplies gas service. Such franchises are perpetual but remain subject to the power of alteration, amendment or repeal by the General Assembly of the State of Connecticut, the power of revocation by the DPUC and certain approvals, permits and consents of public authorities and others prescribed by statute. Yankee Gas franchises include, among other rights and powers, the rights and powers to manufacture, generate, purchase, transmit and distribute gas, to sell gas at wholesale to other utility companies and municipalities and to erect and maintain certain facilities on public highways and grounds, all subject to such consents and approvals of public authorities and others as may be required by law. The franchises include the power of eminent domain. EMPLOYEES Yankee Energy has no employees. Its subsidiaries employ approximately 830 people. FORWARD-LOOKING STATEMENTS This report contains statements which, to the extent they are not recitations of historical fact, constitute "forward-looking statements" within the meaning of the Securities Litigation Reform Act of 1995. Such forward-looking statements, including statements regarding the Company's expectations for demand and sales of natural gas and related services, involve risks and uncertainties. Actual results may differ materially from such forward-looking statements for reasons including, but not limited to, changes to and developments in the legislative and regulatory environments affecting the Company's business, the impact of competitive products and services, changes in the natural gas industry caused by deregulation, weather and other factors, certain environmental matters, internal and/or third party delays or failures in achieving Year 2000 compliance and other risks described in this report and the Company's other filings with the Securities and Exchange Commission. ITEM 2. PROPERTIES Yankee Gas' property consists primarily of its gas distribution facilities including, distribution lines (mains and services), meters, pumps, valves and pressure and flow controllers. Yankee Gas owns various propane facilities with a combined storage capacity equivalent to approximately 245,000 Mcf. In the opinion of management, Yankee Gas' distribution system is in good condition. Virtually all of the gas properties are subject to the lien of the Yankee Gas first mortgage bond indenture. Yankee Gas also owns service buildings in Meriden, Waterbury, Torrington, Mystic, Shelton, Bethel and Danielson, Connecticut. NorConn owns the Company's headquarters building in Meriden, Connecticut and currently leases it to Yankee Gas. This is the site of the Company's corporate administrative and staff functions including the Customer Service Center. NorConn also owns and leases to Yankee Gas a service building in East Windsor. ITEM 3. LEGAL PROCEEDINGS Municipal Tax Assessment. In fiscal 1996, Yankee Gas received revised property tax bills from the City of Meriden, Connecticut (the "City"). The City is asserting a claim for the payment of approximately $5.0 million of back taxes and interest resulting from a retroactive reassessment and revaluation of Yankee Gas' personal property filings. The City did not locate or identify any property which Yankee Gas omitted from its filings. The tax bills reflect a reassessment of property at higher rates than those previously assessed by the City. Yankee Gas is currently in the process of litigating this retroactive reassessment and the Court recently recommended that the parties attempt mediation/arbitration of the issue. The parties have begun the process and are currently selecting a mediator acceptable to both. Although it is anticipated that the outcome of the City's claim will not have a material impact on the Company, based on the information available at this time, management cannot predict what the ultimate impact might be. Licensing Issue. In November 1995, The Connecticut Heating and Cooling Contractors Association, Inc. and others filed a purported class action suit against Yankee Gas and Connecticut's two other LDCs, Connecticut Natural Gas Corporation and The Southern Connecticut Gas Company in Connecticut Superior Court. The action alleges that the LDCs unfairly competed with licensed plumbers and contractors by performing customer service work using employees who did not possess Connecticut state trade licenses. In January 1998, the court struck 31 of the plaintiffs' 32 counts contained in their complaint, leaving one count alleging violations of Connecticut's antitrust statute. The court also ruled that although the plaintiffs' action purported to be a class action, the plaintiffs failed to obtain certification as such. Thereafter, the plaintiffs filed another purported class action against all three LDCs alleging unfair trade practices and additional separate actions against each LDC alleging various business torts. The LDCs have asserted that such licenses are not required for this work based on a statutory exemption enacted in 1965 and amended in 1967. However, in a separate proceeding, a Connecticut Superior Court has upheld an administrative ruling against the LDCs' position, which was affirmed on appeal. In 1995, the Connecticut General Assembly enacted legislation that established prospectively a separate procedure for State certification of gas service employees. Recently, the lawsuits were transferred to the Complex Litigation Docket of the Superior Court where the presiding judge chose to try the case against Connecticut Natural Gas ("CNG") first and no other material action in Yankee Gas' lawsuit will be taken pending the outcome of the CNG trial which is expected to commence in August 1999. While the ultimate results of the suits cannot be determined, management does not expect that they will have a material adverse effect on the Company's consolidated results of operations or financial position. Other legal proceedings involving the Company and its subsidiaries are litigation incidental to the conduct of the Company's business which, in management's opinion, will not have a material impact on the Company's financial condition or results of operation. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS There was no matter submitted to a vote of security holders during the fourth quarter of 1998. EXECUTIVE OFFICERS OF THE COMPANY NAME AGE POSITION AND BUSINESS EXPERIENCE DURING PAST FIVE YEARS - ---- --- ------------------------------------------------------- Charles E.
