Bottom right: Photo inset of man in hard hat checking equipment Photo inset of Big Mo - Yankee Gas Mobile Office Vehicle Bottom center: YES 1997 Bottom right: 1 Top half of page: Photo inset of Branko Terzic wearing hard hat, job site in background Chairman's Letter: A Letter from Branko This year -- a year of transition for your company, Yankee Energy System, Inc. -- earnings from our regulated subsidiary, Yankee Gas Services Company, were strong (despite the warm weather). Yet losses from last year s startup diversification effort in Yankee Energy Services Company (YESCo) meant our total earnings for the year were less than anticipated. The earnings for 1997 of $1.62 a share were down from the previous year s earnings of $2.10, based on warmer weather and other variables. The prior year s figure benefited from a $0.24 per share gain on the sale of our interest in the Iroquois Pipeline. As an additional point of reference, 1995 earnings were $1.20 per share (this included a one-time charge of $0.30 per share related to the company s business re-engineering efforts). Focused strategy, improved management I take responsibility for our results and wish to inform you that Yankee Energy is applying the lessons learned from our experience this past year. As we begin a new fiscal year, strategic focus has been sharpened, managerial improvements have been made, and operating performance has improved. Our strategy to increase shareholder wealth has not deviated from its path. We will continue to improve the efficiency and sales effectiveness of Yankee Gas Services Company while creating new earnings in our YESCo subsidiary by focusing on energy-related mechanical services, first in Connecticut and then in the rest of New England. This strategy fits well with the changes now driving the energy sector of the U.S. economy. As I reported in last year s letter, all indicators point to increased competition in the energy industry. Thus, Yankee Energy s prospects continue to be influenced by often unpredictable changes in state and federal regulation of natural gas and electricity. Deregulation and increased opportunities Last year, competition was introduced in Connecticut by a Department of Public Utility Control (DPUC) decision allowing commercial and industrial customers to purchase commodity gas on the market. This year, the DPUC has opened a proceeding to take evidence and testimony on the issue of residential customer choice in gas purchased from other marketers. Since Yankee Gas has successfully implemented transportation services to commercial and industrial customers, we are well-positioned to provide residential gas transportation services. This new service will be boosted by use of our automatic meter reading capability and new informational technology investments. Bottom left: 2 Bottom center: YES 1997 Changes in electric regulation -- particularly new laws facilitating distributed electric generation -- will present a number of opportunities for Yankee Energy subsidiaries. As the largest gas distribution system in Connecticut, Yankee Gas is ready to provide gas sales or gas delivery services to newly constructed gas-fired electric generation facilities. Any new construction of small distributed power plants also creates a market for YESCo, which can provide installation, operation and maintenance services for these types of energy conversion technologies. Diversification moves Yankee closer to customers In contrast to the strategies of many other utilities, Yankee Energy System has chosen to offer "technicians and trucks" through our YESCo subsidiary. Many national companies advertising "energy services" through telemarketing or direct mail are not able to provide these capabilities. Yankee Energy System s diversification strategy is to extend services beyond gas delivery. This means we will offer services on the customer s side of the meter for energy conversion, control, and gas-using devices. Thus, YESCo revenues will increase by providing highly trained and well-equipped field personnel to meet customers needs on-site. YESCo has chosen as its initial service area a region that will benefit from the proximity of Yankee Gas Services. YESCo has chosen as its market segment industrial and commercial targets whose need for mechanical and energy-related services will, within a short time, enable YESCo to become a regional market leader. To enhance our competitive position further, YESCo customers will have the convenience of one-stop financing from its affiliate, Yankee Financial Services Company. Our mission is to increase shareholder value. Yankee Energy will accomplish that mission by the creation of service offerings that will provide our customers with "imaginative and responsive energy solutions." Everyone at Yankee Energy clearly understands that mission. We believe our plan to be well-designed with an appropriate balance of risk and growth. Recent additions to management have strengthened our organization and increased our prospects for financial success even more. I am keenly aware of your expectations as shareholders and of my own responsibilities as Chief Executive Officer of your company. Please feel free to contact me at any time with your critiques, comments, or suggestions concerning your company s performance.

Upper Left: Yankee Gas Photo inset: Charles E. Gooley Upper Right: We're closer to customers, and our sales show it. Growth is the principal indicator of the health of any business, and 1997 sales results clearly show the strength of our anchor company, Yankee Gas, and the improved economic conditions in the areas we serve. We have reorganized our sales force under experienced sales and marketing professionals and doubled our historic rate of customer growth, adding more than 2,300 new customers. We exceeded our sales growth projections by more than 52 percent. Even as we meet the growing demands of almost 160,000 residential energy customers, we added 30 percent more appliance-service customers in 1997. Yankee Gas also was Connecticut s leader in promoting firm transportation services, making our infrastructure available to customers who choose to buy their own gas, and rely upon our distribution system to deliver it. We identified gas-fired electricity generation opportunities and effectively marketed them to businesses throughout the state. Our gas cooling, air compression, infrared heating and natural gas vehicle programs all moved forward. As we grew the business, we tightly controlled operating, maintenance, and capital expenditures. Aggressive goals set for all areas of operations were mostly met or exceeded. That was last year. To succeed in 1998 and the longer term, we need to have a clear understanding of what we are and must be to our customers. We are a quality provider of natural gas distribution and utilization services. We sell gas to those customers who want to buy from us, and we deliver gas for other customers who want to buy their own gas. We provide appliance and equipment installation, maintenance and service directly to our residential customers. To prosper in the future, Yankee Gas must consistently be named by customers as one of the top service companies with which they do business. We no longer compare ourselves only to public utilities, because our customers ceased doing that long ago. We are now compared to the package delivery company, the lawn service, and the local building contractor. Our service must rival that of the "best in its class" of any type of company serving consumers. Because the price of energy is a primary customer concern, we must keep our prices competitive with those of other energy providers. We will do this through aggressive cost management and sales efforts focused in areas where we already have distribution facilities. Yankee Financial will continue to support our ability to make natural gas an affordable option. As changes in regulation require our customers to make choices, we will be the source for clear, reliable information. Technology does and will continue to play a major role in our customer interactions, as is evidenced by our comprehensive Web site and a new customer information system, scheduled for completion next Fall. But technology will not replace the motivated, well-trained, and courteous employees who have come to exemplify Yankee Gas. Rather, it will enable them to delight our customers. Customer delight, not customer satisfaction, is the new target at which we are aiming. Charles E. Gooley signature Charles E.

Upper right: Photo inset of Michael E. Bielonko Yankee Energy Services Company (YESCo) is being positioned in the marketplace to provide a full range of energy equipment mechanical services to commercial, industrial, and institutional customers through YESCo s three divisions: Power, Controls, and Services. YESCo s Power division designs, builds and maintains on-site facilities for the production of thermal and/or electric power. This includes fuel cells, of which YESCo Power installed two in the fourth quarter of fiscal 1997, and began its third installation in the first quarter of 1998. YESCo Controls specializes in the engineering, installation, and maintenance of building control systems. Controls is an authorized installer of Andover Controls, a leading building controls product that we are now installing in major projects for customers such as Southern New England Telecommunications (SNET) and the University of Connecticut. YESCo Services now operates out of three locations, two in Connecticut and one in Massachusetts, to provide comprehensive HVAC, boiler, and refrigeration equipment services and installation. In fiscal 1997, YESCo incurred startup costs at new locations associated with building a sales and marketing infrastructure, and initiated negotiations that led to acquisitions just after the end of the fiscal year. Several on-site energy generation projects expected to begin in fiscal 1997 were also delayed to early 1998. Nonetheless, our identity as a provider of comprehensive energy-related mechanical services is taking shape as we continue to provide excellent service. Substantial progress was made against our aggressive multi-year business plan. In the third quarter we established two additional operations service centers, one in southern Connecticut and one in eastern Massachusetts. Late in the fourth quarter we completed two acquisitions that enhance our technical capabilities in both our Controls and Services divisions. Our goal is to become the largest provider of comprehensive mechanical services in Connecticut and adjacent markets. In fiscal 1998 we plan continued growth internally through targeted sales efforts and acquisitions. All the necessary managerial, financial, and cultural components are in place to enable us to create real shareholder value and continue our acquisitions program. Our strategy of "technicians and trucks" dispatched to provide on-site solutions for customers remains sound. In keeping with the character of Yankee Energy System, YESCo is set for long-term, steady growth. Michael E. Bielonko signature Michael E.

The system, created by IBM Global Services, is a first in the natural gas industry and will provide fast access to data on customer billing, sales, credit, repairs and maintenance. Yankee believes the system will enhance the company s growth strategies. Charles Gooley, president of Yankee Gas, pointed out that "utility customers will compare their utility providers' service to all other service providers. The IBM-CSS system will help us provide the service that will distinguish us from everyone else." The installation is scheduled for completion in late 1998.

And, like almost 1,400 of those customers, Federal Paper Board uses a marketer to supply their natural gas while relying on Yankee to transport it to their factory. We're proud to serve these transportation customers. Bottom left: 6 Bottom center: YES 1997 Top center: Service contracts soar Word in background beneath copy: Growth The growth of gas-appliance service contracts sold by Yankee Gas skyrocketed this past year, exceeding all expectations. "We marketed more aggressively than ever," said Yankee Vice President of Marketing Steve Laden. "Seasonal specials and add-on contracts for installations, conversion projects and new homeowners resulted in thousands of new service contract customers." Laden added that service contracts do more than provide another revenue stream. "Having a contractual relationship with customers encourages them to communicate with us," he said. "It s another way of listening to them and staying in touch with what they want."

Right margin: CAD keeps Yankee Service running on time When a request for service comes in to Yankee Gas, vehicles are responding more efficiently because of Computer Aided Dispatch (CAD). The system, installed last summer, coordinates a fast response by linking service headquarters to computer terminals in service vehicles. Yankee personnel are directed to the customer and already informed about the nature of the problem when they arrive. As the Yankee customer base expands in number and in geographic distribution, CAD will keep Yankee service pointed in the right direction. Yankee OnCall completes customer service loop Graphic of Yankee OnCall logo Yankee Gas has traditionally provided natural gas to its customers and provided service or repair work when needed. But when residential customers wanted to buy and install natural-gas equipment, Yankee could only recommend a contractor. Yankee OnCall changes all that. Yankee OnCall is an equipment-acquisition and installation service for residential customers. "The customer benefits from better, more competitive service through Yankee," said David Ferrante, director of customer service. "And we re now able to provide energy solutions seamlessly, from acquisition to installation, delivery, service, and repairs."

Martha Stewart has the last word on how to address domestic dilemmas, from making artichoke dip to baking zucchini bread. And she wouldn't cook with anything but natural gas. "For precision cooking, nothing comes close to natural gas," she said from her studio in Norwalk, where Yankee recently completed a conversion that enabled the construction of two commercial-grade kitchens. With gas now on-line for her new daily television show, "Martha Stewart Living," the star will saute, bake, broil, and boil with the accuracy for which she s known. "We worked closely with our customer on this project," said Yankee Gas Sales Representative Mike Collins. "We designed subfloor lines to suit the studio layout. Once it was done, we convinced Ms. Stewart to make her heating system natural gas, too, and converted the whole building." Look for Martha Stewart s new syndicated television show, and look for the Yankee Gas name when the credits roll. Yankee answers the need for cleaner power The problem at the Laurel Gardens apartments wasn't that oil heat was costly. It was that oil heat created maintenance problems and environmental issues for the community. Enter Rick Hughes, the Yankee Gas sales representative who called the Director of Danbury's Housing Authority last February. He showed the Director how natural gas could help improve air quality, and today has converted 90 units in five apartment buildings. "The tenants get cleaner heat. And Yankee gets more satisfied customers on-line," said Hughes. Yankee Gas is now focused on similar properties in Danbury -- and the other 67 towns in the service area -- that could use cleaner energy. Bottom left background text: air quality Bottom right: Stonegate finds a cure for the common cold Stonegate was a cold neighborhood. Ninety single-family Stamford homes, all with poor insulation, all heated by electric heat pumps. Each winter, kids got sick and the electric bills soared. Yankee Gas Sales Representative Greta Mead connected with a resident who wanted to sell his home, but because of the electric heat, couldn't get the price he wanted. Together, they attended neighborhood meetings, stuffed flyers in mailboxes, and discovered a market ripe for natural gas. "It was a domino effect," said Mead. "Momentum built on word of mouth, and eventually we converted 60 of the 90 homes to natural gas." Now natural gas furnaces, fireplaces, and water heaters are getting hot. And kids are staying warmer.

The move is expected to reduce Yankee s role as seller of natural gas, and open up new sales opportunities in gas transportation. Hence the formation of a new department: Transportation Services. Transportation Services makes Yankee a partner with customers who need gas and with those who supply gas, by providing the infrastructure that enables gas to arrive at its destination. No matter where customers buy their gas, Yankee gets it there. The new department will also coordinate with Sales to identify transportation-related business opportunities. "We can communicate with people who need gas, and people who supply it," said Richard Tardif, manager of Transportation Services. "This will keep our sales staff supplied with the market information they need, and administer customer requests more effectively."

Right margin: Background photo: Closeup of computer keyboard EBB and flow. On-line natural gas ordering heats up. Now that marketers are opening up natural gas sales, they rely on Yankee Gas more than ever for timely delivery of the product. For this reason, Yankee has established an Electronic Bulletin Board, operational since last summer. The EBB keeps communications with marketers constant, current, and paperless. Orders for natural gas arrive instantly. Marketers receive daily summaries of account activity. The database information is entered once (instead of twice, under the previous faxing method). And, since EBB uses the Internet, no additional hardware or software is required. Bottom line: Customers get the gas they need at competitive prices when they need it.

Infrared heats up; air compression performs under pressure. Background text: infrared Owners of large facilities like warehouses, garages, and airplane hangars have traditionally paid a premium to keep their vast space warm enough to work in during cold, drafty winter months. Until recently, that is. Natural gas-based infrared heating is now replacing older, colder convection heating systems by putting warm air into cold work areas. Infrared heaters heat buildings the same way the sun heats the Earth s surface. Ceiling-mounted units radiate heat that warms walls, floors, equipment and people. Comfort is increased and heat loss is minimized. This explains why infrared heat is now warming an Air National Guard hangar, a large auto-service garage, and a manufacturing facility, all in Connecticut. Other firms are recognizing the benefits of natural gas as a power source for air compression, important in many manufacturing processes. Natural gas-fired air compression is cheaper than electricity, and more reliable, too, since it keeps manufacturers going during power outages. These are just a few reasons why Yankee Gas sees great potential in both these technologies, and will market them aggressively in 1998. Bottom right background text: air compression Bottom left: 10 Bottom center: YES 1997 Top left: Environment Background copy across pages 10 and 11: Technology Environment Economics NGV's hit the road Natural Gas fleets expand United Parcel Service and the U.S. Postal Service have added natural gas-powered trucks to their Connecticut fleets, leading the movement toward more fuel-efficient vehicles on our roads and providing Yankee Gas Services sustained growth in the business of engine conversions and fuel supply. Federal laws mandate that certain fleets begin using alternative fuels, so companies like UPS and the Postal Service are preparing for the future. Ford, GM, and Chrysler all have plans for natural gas vehicle (NGV) production as well. For many companies, the reasons go beyond federal law. Natural gas is less expensive -- about 90 cents a gallon -- and cleaner-burning than gasoline, emitting approximately 90 percent less carbon monoxide. Maintenance costs are lower and safety is higher, since natural gas combusts at twice the temperature of gasoline. That s smart driving. NGVs are especially well-suited to fleet service, since such vehicles rely on central fueling stations, of which Yankee now has five in Connecticut. The latest, at Danby's Exxon station in Meriden, was constructed by Yankee Gas Services last year, adding a critical centrally located link in the state s natural gas fuel network. Check out our web site for other locations. Top right: Photo inset of man fueling UPS vehicle Bottom third: Fuel cells power up. Natural gas goes in, premium AC power comes out. Fuel cells first caught the attention of NASA, which is always looking for new ways to supply power in outer space. Back here on Earth, YESCo is marketing fuel cell technologies for business, highlighting the company s drive to fill the demands for non-traditional, reliable, premium power generation. Fuel cells are currently operating at the Naval Submarine Base in Groton as well as Yankee s corporate headquarters. Fuel cells create AC power by separating the hydrogen and oxygen in natural gas. Thermal energy is also produced, and can be recovered and re-used. The power output from one fuel cell can reach 200 kilowatts at 85 percent efficiency, enough power for about 150 homes. Right now the up-front cost of fuel cells is steep, but the federal government subsidizes their development, making them more affordable. Still, the appeal of fuel cells remains high. They ensure clean, high-quality power even during power outages, eliminate the need for expensive backup systems, and because the current is steady, fuel cells extend the life of the equipment they power. Natural gas fuel cells produce no emissions, so they re easy on Mother Nature. As the demand for fuel cells in the premium power market grows, YESCo will be there to meet it.

(YES or the Company) headquartered in Meriden, Connecticut, is a diversified company specializing in the distribution, conversion, and control of energy to meet our customers' needs. Our principal operating subsidiary is Yankee Gas Services Company (Yankee Gas). Yankee Gas provides retail distribution of natural gas to a service area of 68 cities and towns in Connecticut. The Company's other operating subsidiaries support our core business in natural gas, or allow us to expand our growing businesses in energy-related services. Yankee Energy Services Company (YESCo) provides comprehensive energy-related services through three principle divisions. YESCo Power designs, builds and maintains on-site facilities for the production of thermal and/or electric power. YESCo Controls is in the business of engineering, installing, and maintaining building control systems. YESCo Services provides comprehensive HVAC, boiler and refrigeration equipment services and installation. Other subsidiaries support the operations of Yankee Gas and YESCo. NorConn Properties, Inc. (NorConn) owns selected system real estate, which it leases to Yankee Gas. Yankee Energy Financial Services (Yankee Financial) provides energy equipment financing. R.M. Services, Inc. (RMS) provides receivables management services. The Company reported consolidated net income of $16.9 million, or earnings per share of $1.62, for its fiscal year ended September 30, 1997. This compares with consolidated net income of $21.9 million and $12.4 million, reflecting earnings per share of $2.10 and $1.20, respectively, for fiscal years ended September 30, 1996 and 1995. Fiscal 1996 earnings include a gain of $2.5 million or an after-tax effect of $0.24 per share resulting from the Company's sale of its Iroquois Gas Transmission System (Iroquois) investment. Fiscal 1995 earnings reflect a one-time operating charge of $5.4 million related to the Company's business transformation efforts, or an after-tax effect of $0.30 per share. Earnings for fiscal year 1997 decreased primarily due to operating losses incurred by the Company's non-regulated subsidiaries. Delays in bringing new business on line and integrating these companies into the Yankee Energy organization have contributed to losses which are expected to be eliminated in the next fiscal year. These losses were partially offset by strong operating performance at Yankee Gas during the fiscal year due primarily to a reduction in Operation and Maintenance expense principally as a result of cost controls implemented by the Company. The increase in 1996 earnings from fiscal 1995 was due primarily to colder weather in fiscal 1996, the gain realized on the sale of the Company's 10.5 percent equity interest in Iroquois, and lower expenses relating to the Company's business transformation. Earnings on the Company's investment in Iroquois for the first six months of fiscal 1996 were approximately $1.5 million and contributed $0.14 to earnings per share as compared to $0.4 million in fiscal 1995, or $0.04 per share. On April 30, 1996, the Company announced the sale of its entire 10.5 percent interest in Iroquois. Earnings for fiscal 1996 reflect a $2.5 million net after-tax gain from the sale, or $0.24 per common share, realized in the third quarter of fiscal year 1996. Thus, total earnings related to the investment in Iroquois, including the gain on sale, were $0.38 per common share. The Company increased dividends paid per share to $1.32 in 1997, up 3.1 percent from the $1.28 per share in 1996, the seventh straight year the Company has increased its dividend. Fiscal 1997 earnings per share are based on 10,451,165 weighted average common shares outstanding. Earnings per share were based on 10,435,231 and 10,322,447 weighted average common shares outstanding for fiscal years 1996 and 1995. During fiscal 1997, the Company issued 4,860 new shares of common stock under its Long-term Incentive Plan. In fiscal 1996, the Company issued 52,212 new shares under its Shareholder Investment Plan and 820 shares under its Long-term Incentive Plan. REGULATORY MATTERS On August 25, 1996, Yankee Gas filed an application with the Connecticut Department of Public Utility Control (DPUC) for a Financial and Operational Review (Review). This Review was required under Connecticut statute since Yankee Gas had not undergone a rate proceeding within the previous four years. Yankee Gas' last rate approval was on August 26, 1992, and this Review was necessary to comply with the statute. On July 9, 1997, the DPUC issued its decision in Docket No. 96-08-05. The DPUC decision, which is not a rate order, called for a lowering of Yankee Gas' authorized Return on Equity (ROE) from 12.43 percent to 11.15 percent. The DPUC believed that lower current interest rates and recently allowed rates of return for other Connecticut utilities justified a lower ROE for Yankee Gas. On October 1, 1997, the DPUC approved a settlement whereby Yankee Gas will credit approximately $3.2 million to firm sales customers through the Purchased Gas Adjustment Clause (PGA), during the period November 1997 through March 1998. The settlement also allows Yankee Gas to maintain its base rates until the end of fiscal year 2000, resulting in an eight-year period in which Yankee Gas will have gone without an increase to its base rates. On January 3, 1996, the DPUC issued a Final Decision in reopened Docket No. 92-02-19 to approve a rate agreement Yankee Gas reached with the Office of Consumer Counsel (OCC). The agreement states that Yankee Gas may apply a portion of credits received from pipeline refunds, excess interruptible margin, deferred gas costs, capacity release agreements and off-system sales margin to reduce or eliminate certain deferred regulatory assets. These credits are provided by a mechanism established by the DPUC for the Connecticut Local Distribution Companies (LDCs) to recover the gas supply transition costs relating to Federal Energy Regulatory Commission (FERC) Order No. 636. Through September 30, 1997, Yankee Gas has paid approximately $19.5 million of gas supply transition costs and an additional $3.5 million are anticipated. To date, Yankee Gas has collected $44.2 million through a combination of credits received from pipeline refunds, capacity release agreements, deferred gas costs, off-system sales margin, and excess interruptible margin. These excess collections of approximately $24.7 million have been applied against certain regulatory assets in accordance with the January 3, 1996 DPUC decision. On August 2, 1995, the DPUC issued a Final Decision in Docket No. 94-11-12, DPUC Review of Connecticut Local Distribution Companies' Cost of Service Study Methodologies. The DPUC investigated the issues surrounding the development of firm transportation (FT) rates at the state level in response to FERC Order No. 636. The Decision provided guidelines for the development of FT rates to be offered by the state's three LDCs. On January 24, 1996, the DPUC issued a Final Decision on Docket No. 92-02-19 Reopen I. This Decision enabled Yankee Gas to implement FT rates and services as contemplated in the DPUC August 2, 1995 decision referenced above. The Decision allows Yankee Gas to offer a broad array of service options to commercial and industrial FT customers. Yankee Gas implemented these new FT rates and services on April 1, 1996, and as of September 30, 1997, Yankee Gas had approximately 1,460 customers under the new FT service. Existing customers who switch to transportation tariffs will result in decreased revenues for Yankee Gas as that portion of revenues representing gas costs will now be borne directly by those customers who buy their gas directly. Yankee Gas 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. 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 Private Securities Litigation Reform Act of 1995. Such forward-looking statements 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 and other factors, and certain environmental matters, as well as such other factors as set forth in the Company's Form 10-K for the year ended September 30, 1997. RESULTS OF OPERATIONS OPERATING REVENUES Operating revenues decreased $14.9 million from 1996 to 1997 and increased $45.9 million from 1995 to 1996. The components of the change in operating revenues for the past two years are provided in the following table: (Millions of Dollars) Increase/(Decrease) Years Ended September 30, 1997 vs 1996 1996 vs 1995 Firm sales and other $ (9.0) $12.7 Firm transportation 7.2 (0.4) ____ ____ Subtotal firm sales, transportation and other (excluding gas cost recoveries) (1.8) 12.3 Interruptible/off-system sales and transportation (excluding gas cost recoveries) (1.4) 0.2 ____ ____ Total (excluding gas cost recoveries) $ (3.2) $12.5 Gas cost recoveries (16.9) 32.5 _____ _____ Total change in utility revenues $ (20.1) $45.0 _____ _____ _____ _____ Nonutility revenues 5.2 0.9 Total change in operating revenues $ (14.9) $45.9 _____ _____ _____ _____ The corresponding changes in Yankee Gas throughput were as follows: (Mcf-thousands) Increase/(Decrease) Years Ended September 30, 1997 vs 1996 1996 vs 1995 Firm sales (3,692) 4,485 Firm transportation 3,881 (411) Interruptible/off-system sales (2,937) (342) Interruptible transportation 4,409 (1,210) _____ _____ Total change in throughput 1,661 2,522 _____ _____ _____ _____ The change in operating revenues primarily reflects a decrease in firm sales volumes of approximately 10.5 percent in fiscal 1997 compared to fiscal 1996. This change primarily related to the shift of firm sales to firm transportation and a decrease in residential sales volumes related to warmer weather. Firm transportation increased approximately $7.2 million from 1996 to 1997. The increase in firm and other revenues from 1995 to 1996 was due primarily to weather that was 13 percent colder in 1996, partially offset by an 11.5 percent decrease in off-system sales, interruptible sales and transportation from 1995 to 1996. Revenues from non-regulated operations increased $5.2 million from 1996 to 1997 and $0.9 million from 1995 to 1996 due to the growth of nonutility subsidiaries during those years. Gas cost recoveries decreased in fiscal 1997 compared to fiscal 1996 due to lower firm sales, offset by higher per-unit gas costs. Gas cost recoveries increased in fiscal 1996 compared to fiscal 1995 due to higher firm sales and higher per-unit gas costs. OPERATING EXPENSES Total operating expenses decreased $11.2 million in 1997 compared to 1996 and increased $34.1 million in 1996 compared to 1995 as a result of the following items: Cost of gas decreased $16.4 million in 1997 compared to 1996 and increased $33.8 million in 1996 compared to 1995. Yankee Gas defers differences between actual purchased gas costs and the current cost recovery and recovers or refunds such differences in future periods. This deferral results in an increase or decrease to gas costs in each fiscal year. The 1997 decrease was due primarily to lower firm sales as a result of the warmer weather, partially offset by higher per-unit gas costs. The 1996 increase was primarily due to higher volumes of gas purchased as a result of the colder weather and full recovery of the prior year undercollection of gas costs. Cost of goods sold increased $3.6 million in 1997 compared to 1996, due to increased YESCo activity. Operation and maintenance expense increased $0.1 million in 1997 compared to 1996 and decreased $0.6 million in 1996 compared to 1995. The 1997 increase was primarily due to increased expenses related to nonutility operations, partially offset by a decrease in Yankee Gas operation and maintenance expense. Depreciation expense increased $0.9 million in 1997 compared to 1996 and increased $0.1 million in 1996 from 1995 levels. The 1997 increase was primarily due to additions in plant assets. Taxes other than income taxes increased $0.6 million in 1997 compared to 1996 and increased $0.5 million in 1996 compared to 1995. The 1997 increase was primarily due to higher Connecticut unemployment taxes and municipal taxes, partially offset by lower gross earnings taxes resulting from lower revenues in 1997 compared to 1996. The 1996 increase was primarily due to higher gross earnings taxes which resulted from higher revenues in 1996 compared to 1995, and higher municipal taxes, partially offset by a reduction in Connecticut state unemployment taxes. The 1997 increase and 1996 decrease in Connecticut unemployment taxes was due to a decision by the Connecticut Supreme Court concerning the Company's 1992 work stoppage which allowed the Company to reverse, in fiscal 1996, an accrual for unemployment tax expense associated with claims paid to Yankee Gas bargaining unit employees in 1992. Other income decreased $5.4 million in 1997 compared to 1996 and increased $2.7 million in 1996 compared to 1995. The 1997 decrease was primarily due to the absence of earnings associated with the Company's interest in Iroquois, while the 1996 increase was primarily due to the gain on the sale of the Company's interest in Iroquois. Interest expense in 1997 decreased $2.1 million as compared to 1996 primarily due to lower levels of debt and lower interest expense on Yankee Gas' deferred fuel balance. Interest expense in 1996 decreased $0.2 million as compared to 1995 primarily due to lower debt, offset by higher interest on Yankee Gas' deferred fuel balance. Federal and state income taxes decreased $2.0 million in 1997 compared to 1996, and increased $5.2 million in 1996 compared to 1995. The 1997 decrease was primarily due to lower taxable income as a result of operating losses incurred by Yankee Energy's nonutility subsidiaries. The 1996 increase was primarily due to increased earnings from operations over fiscal 1995. Please refer to Note 2 to the Consolidated Financial Statements for additional information concerning the components of federal and state income taxes. LIQUIDITY AND CAPITAL RESOURCES Expenditures for plant, property and investments totaled $35.2 million in 1997 reflecting a $5.2 million increase from 1996, and was funded primarily through cash generated from current operations and short-term borrowings. Cash flow (defined as net income adjusted for non-cash items such as depreciation, deferred income taxes and the Company's non-cash equity earnings from investments) represents the cash generated from operations available for capital expenditures, dividends and other needs. Cash flows from operating activities decreased $7.8 million in fiscal 1997 compared to fiscal 1996 primarily due to lower net income and changes in working capital, and decreased $2.1 million in fiscal 1996 compared to fiscal 1995. The seasonal nature of gas revenues, inventory purchases and construction expenditures create a need for short-term borrowing to supplement internally generated funds. Yankee Gas has arranged a $60 million revolving line of credit with a group of four banks whereby funds may be borrowed on a short-term revolving basis using either fixed or variable rate loans. Yankee Gas also has an additional $27 million of credit lines available on an uncommitted basis. Yankee Gas had $36.3 million outstanding under its agreements at September 30, 1997 and $20.3 million outstanding at September 30, 1996. In addition, Yankee Energy had $2.7 million outstanding as of September 30, 1997 and no amounts outstanding at September 30, 1996 on a $15 million line of credit, which is available to fund the development of the Company's unregulated businesses. The weighted average interest rates on short-term borrowings at September 30, 1997 and 1996 were 6.0 percent and 5.6 percent, respectively. The long-term credit needs of Yankee Gas are being met by a first mortgage bond indenture that provides for the issuance of bonds from time to time as the need arises, subject to certain restrictions. At September 30, 1997, indenture requirements, including the required coverage ratio, would allow for the issuance of an additional $216 million of bonds at an assumed interest rate of 7.4 percent. On February 1, 1996, the Company's system real estate subsidiary, NorConn, secured a $6 million bank term loan to refinance two existing real estate loans. Under the agreement, the interest rate is fixed at 6.24 percent for the seven-year term of the loan and requires an annual $250,000 sinking fund payment. On April 1, 1997, Yankee Gas redeemed all $30 million Series A Tranche C First Mortgage Bonds which matured on that date. Yankee Gas used cash on hand and the issuance of a $30 million principal amount of Series E First Mortgage Bonds on April 1, 1997, through a private placement. The bonds were sold by the initial purchaser to "qualified institutional buyers" as defined in and pursuant to Rule 144A under the Securities Act of 1933. The bonds will mature April 1, 2012 and interest is payable at an annual rate of 7.19 percent. On November 4, 1994, Yankee Energy filed a Form S-3 registration statement with the Securities and Exchange Commission to issue up to 1,200,000 shares of common stock under its proposed Shareholder Investment Plan (Plan). The Plan, which became effective January 25, 1995, provides existing shareholders and their family members the ability to acquire shares of common stock through dividend reinvestment or voluntary cash purchases. The Plan provides the Company the option to use new shares of common stock or market purchases. The Company issued 52,212 new shares which provided approximately $1.0 million of new equity funding in fiscal 1996. No shares were issued under the Plan during fiscal 1997. The new equity was used primarily to provide capital contributions to the Company's nonregulated subsidiaries. The Company's estimated capital expenditures for the fiscal years 1998 through 2002 are $194 million, including $55 million for 1998. Approximately $54 million, including $15 million for 1998 is for capital expenditures in nonutility operations. The 1998 utility capital expenditures, including the installation of a new customer information system, are expected to be financed by a combination of internally generated funds and short-term borrowings. For Yankee Gas, long-term debt maturities and sinking fund requirements will total $3.4 million in 1998. The Company is currently implementing new systems and enhancing existing systems to address year 2000 issues. Management believes that all system changes will be installed and tested prior to the manifestation of year 2000 issues. Currently, all such charges associated with system enhancements have and will continue be expensed and the costs of new systems will be capitalized as appropriate. Expenditures are expected to continue through the next two fiscal years. In addition, Yankee Gas expects to incur expenditures for coal tar remediation efforts, which is more fully discussed in Note 9 to the Consolidated Financial Statements. Yankee Gas expects to finance such expenditures through a combination of internally generated funds, short-term debt, and through insurance settlements, which have totaled $9.6 million as of September 30, 1997. MANAGEMENT REPORT The consolidated financial statements of Yankee Energy System, Inc. and subsidiaries and other sections of this Annual Report were prepared by management, which is responsible for their integrity and objectivity. These financial statements, which were audited by Arthur Andersen LLP, were prepared in accordance with generally accepted accounting principles using estimates and judgement, where required, and giving consideration to materiality. The Company maintains a system of internal controls over financial reporting, which is designed to provide reasonable assurance to the Company's management and Board of Directors regarding the preparation of reliable published financial statements. The system contains self-monitoring mechanisms, and actions are taken to correct deficiencies as they are identified. Even an effective internal control system, no matter how well designed, has inherent limitations, including the possibility of the circumvention or overriding of controls, and such systems can provide only reasonable assurance with respect to financial statement preparation. Further, because of changes in conditions, internal control system effectiveness may vary over time. Through established programs, the Company regularly emphasizes to its management employees their internal control responsibilities and policies prohibiting conflicts of interest. The Audit Committee of the Board of Directors is composed entirely of outside directors. This Committee meets periodically with management, the internal auditors and the independent auditors to review the activities of each and to discuss audit matters, financial reporting and the adequacy of internal controls. Management believes that its system of internal accounting controls and control environment provide reasonable assurance that its assets are safeguarded from loss or unauthorized use and that its financial records, which are the basis for the preparation of all financial statements, are reliable. Branko Terzic Chairman, President and Chief Executive Officer James M. Sepanski Vice President, Chief Financial Officer and Treasurer REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Board of Directors and Shareholders of Yankee Energy System, Inc.: We have audited the accompanying consolidated balance sheets and consolidated statements of capitalization of Yankee Energy System, Inc. (a Connecticut corporation) and subsidiaries (the Company) as of September 30, 1997 and 1996, and the related consolidated statements of income, common shareholders' equity and cash flows, for each of the three years in the period ended September 30, 1997. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audits 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 Yankee Energy System, Inc. and subsidiaries as of September 30, 1997 and 1996 and the results of their operations and their cash flows for each of the three years in the period ended September 30, 1997, in conformity with generally accepted accounting principles.

Under the Long-term Incentive Compensation Plan the market value of the restricted stock awards has been recorded as unearned compensation and is shown as a separate component of shareholders' equity. The earned compensation is charged to administrative and general expense as shares become vested. Earned compensation was approximately $66,000 for fiscal 1997 and $117,000 for fiscal 1996. (b) On July 20, 1989, Yankee Energy became guarantor of a term loan agreement between the Trustee for the Company's 401(k) Employee Stock Ownership Plan (ESOP), and a commercial bank, in the amount of $4,000,000. The proceeds were used by the Trustee exclusively to acquire outstanding shares of Yankee Energy common stock pursuant to the terms of the Company's ESOP. The final maturity date of the agreement is July 1, 1999 with sinking fund requirements of $400,000 for the fiscal year 1998 and $600,000 for the 1999 fiscal year.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1) Summary of Significant Accounting Policies The Company: Yankee Energy System, Inc. (YES or the Company) headquartered in Meriden, Connecticut, is a diversified company specializing in the distribution, conversion, and control of energy to meet our customers' needs. Our principal operating subsidiary is Yankee Gas Services Company (Yankee Gas). Yankee Gas provides retail distribution of natural gas to a service area of 68 cities and towns in Connecticut. The Company's other operating subsidiaries support our core business in natural gas, or allow us to expand our growing businesses in energy-related services. Yankee Energy Services Company (YESCo) provides comprehensive energy-related services through three principle divisions. YESCo Power designs, builds and maintains on-site facilities for the production of thermal and/or electric power. YESCo Controls is in the business of engineering, installing, and maintaining building control systems. YESCo Services provides comprehensive HVAC, boiler and refrigeration equipment services and installation. Other subsidiaries support the operations of Yankee Gas and YESCo. NorConn Properties, Inc. (NorConn) owns selected system real estate, which it leases to Yankee Gas. Yankee Energy Financial Services (Yankee Financial) provides energy equipment financing. R.M. Services, Inc. (RMS) provides receivables management services. Principles of Consolidation: The consolidated financial statements of Yankee Energy include the accounts of all subsidiaries. Intercompany transactions have been eliminated in consolidation. Public Utility Regulation: Yankee Gas is subject to regulation for rates and other matters by the Connecticut Department of Public Utility Control (DPUC) and follows accounting policies prescribed by the DPUC. The Company prepares its financial statements in accordance with generally accepted accounting principles which include the provisions of Statement of Financial Accounting Standards No. 71, "Accounting for the Effects of Certain Types of Regulation," (FAS 71). FAS 71 requires a cost-based, rate-regulated enterprise such as Yankee Gas to reflect the impact of regulatory decisions in its financial statements. The DPUC, through the rate regulation process, can create regulatory assets that result when costs are allowed for ratemaking purposes in a period other than the period in which the costs would be charged to expense by an unregulated enterprise. Following the provisions of FAS 71, the Company has recorded regulatory assets or liabilities as appropriate primarily related to deferred gas costs, pipeline transition costs, hardship customer receivables, environmental cleanup costs, income taxes and postretirement benefits costs. The specific amounts related to these items are disclosed in the consolidated balance sheets. Yankee Gas continues to be subject to cost-of-service-based rate regulation by the DPUC. Based upon current regulation and recent regulatory decisions, the Company believes that its use of regulatory accounting is appropriate and in accordance with the provisions of FAS 71. Revenues: Utility revenues are based on authorized rates applied to each customer's use of gas. Rates can be changed only through a formal proceeding before the DPUC. At the end of each accounting period, a revenue estimate for the amount of gas delivered but unbilled is accrued. Depreciation: The provision for utility depreciation is calculated using the straight-line method based on estimated remaining useful lives of depreciable utility plant in service, adjusted for net salvage value and removal costs as approved by the DPUC. The depreciation rates for the several classes of plant in service are equivalent to an overall composite rate of 3.3 percent in fiscal year 1997, 3.3 percent in fiscal year 1996 and 3.4 percent in fiscal year 1995. Purchased Gas Adjustment Clause (PGA): The DPUC-approved rates include an adjustment clause under which gas costs above or below base rate levels are charged or credited to customers. As prescribed by the DPUC, differences between the actual purchased gas costs and the current cost recovery are deferred and recovered or refunded over future periods. Equity Accounting: The Company accounts for YESCo's investments in energy production facilities using the equity method, recording their proportionate share of earnings (losses) with corresponding increases (decreases) in their investment. Distributions received reduce the carrying amount of these investments. Income Taxes: Differences exist between the periods in which transactions affect income in the financial statements and the periods in which they affect the determination of income subject to tax. The tax effect of such timing differences is accounted for in accordance with the ratemaking treatment required by the DPUC. Additionally, in accordance with FAS 71, as of September 30, 1997, the Company has a deferred tax liability and a corresponding regulatory asset of approximately $11.0 million, due to the effect of Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes". Reclassifications: Certain prior year amounts have been reclassified to conform with current year classifications. Use of Estimates: 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. Impairment of Long-Lived Assets: Yankee Energy adopted Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" (FAS 121), in fiscal 1997. The implementation of FAS 121 did not have a material adverse effect on the consolidated financial statements of Yankee Energy. Earnings per Share: Earnings per share is computed based on the weighted average number of common shares outstanding during each year. The Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 128, "Earnings per Share" (FAS 128). FAS 128 specifies the computation, presentation and disclosure requirements for basic and diluted earnings per share. Yankee Energy will adopt FAS 128 in fiscal 1998, and the Company expects that this statement will have no material effect on earnings per share. Note 2) Income Tax Expense The components of the federal and state income tax provisions are: Years Ended September 30, 1997 1996 1995 (Thousands of Dollars) Charged to income: Current income taxes: Federal $ 4,509 $ 5,297 $ 8,733 State 1,979 894 3,090 ________ _______ _______ Total current 6,488 6,191 11,823 ________ _______ _______ Deferred income taxes, net: Investment tax credits (377) (377) (377) Federal 6,004 8,158 (108) State 1,308 1,479 (1,060) ________ _______ _______ Total deferred 6,935 9,260 (1,545) ________ _______ _______ Total income tax expense $13,423 $15,451 $10,278 _______ _______ _______ _______ _______ _______ Deferred income tax liabilities (assets) are comprised of the following: At September 30, 1997 1996 Depreciation $70,428 $70,118 Other (2,223) (5,696) _______ ______ Net deferred income tax liability $68,205 $64,422 _______ _______ _______ _______ In accordance with required regulatory treatment, deferred income taxes are not provided for certain timing differences. This treatment, along with other items, causes differences between the statutory income tax rate and the effective income tax rate. The differences between the effective income tax rate recorded by the Company and the statutory federal tax rate are as follows: 1997 1996 1995 Federal statutory income tax rate 35.0% 35.0% 35.0% Tax effect of differences: Depreciation 5.1 3.7 5.6 State income taxes net of federal benefit 6.9 3.9 6.1 Effective tax rate adjustment (0.5) (3.0) (1.8) Federal tax credits (1.5) (1.0) (1.7) Bad debt reserve and amortization 0.3 1.7 (1.9) Litigation reserve - (2.0) 3.3 Remediation costs - 1.4 - Miscellaneous (1.1) 1.6 0.8 ____ ____ ____ Effective income tax rate 44.2% 41.3% 45.4% ____ ____ ____ ____ ____ ____ Note 3) Leases Yankee Gas has entered into operating lease agreements for the use of office equipment, vehicles and buildings. For fiscal 1997, 1996 and 1995, these rental payments were $2,064,000, $1,939,000 and $1,751,000, respectively. Future minimum rental payments, excluding associated costs such as property taxes, state use taxes, insurance and maintenance, under long-term noncancelable leases as of September 30, 1997, are approximately: Year (Thousands of Dollars) 1998 $1,791 1999 1,615 2000 1,343 2001 1,056 2002 637 After 2002 586 ______ Future minimum lease payments $7,028 ______ ______ Note 4) Postretirement Benefits The Company has a noncontributory defined benefit retirement plan covering employees of Yankee Gas, YESCo, and RMS. Benefits are based on years of service and employees' highest consecutive 60 months of compensation during the last 120 months of employment. It is the Company's policy to fund annually an amount at least equal to that which will satisfy the requirements of the Employee Retirement Income Security Act and the Internal Revenue Code. No contributions were required or made in fiscal 1997 and fiscal 1996. Pension assets are invested primarily in equity securities and investment grade bonds. The components of net pension cost (credit) were: Years Ended September 30, 1997 1996 1995 (Thousands of Dollars) Service cost $1,992 $1,890 $1,817 Interest cost 4,522 4,216 3,715 Net amortization 13,128 4,373 4,969 Less: Return on plan assets 20,147 10,577 10,524 ______ ______ ______ Net pension credit $ (505) $ (98) $ (23) ______ ______ ______ ______ ______ ______ In addition, in fiscal 1995 a cost of $2,734,000 was recognized as a result of special termination benefits under the pension plan and is included in the Company's 1995 Statement of Income under the Operations category. Total pension cost resulted in income of $420,000 for the year ended September 30, 1997, income of $13,000 for the year ended September 30, 1996 and expense of $62,000 for the year ended September 30, 1995. Pension cost for 1997, 1996, and 1995 includes $85,000 in cost of living increases each year for Northeast Utilities (NU) retirees who were previously employed in the gas business operated by The Connecticut Light and Power Company (CL&P), a subsidiary of NU. These payments were agreed to at the time of divestiture from NU. For calculating the plan's cost and year-end funded status, the following assumptions were used: Years Ended September 30, 1997 1996 1995 Discount rate 7.50% 7.75% 7.75% Expected long-term rate of return 9.00% 9.00% 9.00% Compensation/progression rate 4.50% 4.50% 4.50% The following table represents the plan's funded status reconciled to the consolidated balance sheets: At September 30, 1997 1996 (Thousands of Dollars) Accumulated benefit obligation, including $50,045 of vested benefits at September 30, 1997 and $46,113 at September 30, 1996 $51,210 $47,220 _______ _______ _______ _______ Projected benefit obligation $64,845 $60,053 Less: Market value of plan assets 89,966 72,969 _______ _______ Plan surplus 25,121 12,916 Unrecognized transition amount (703) (789) Unrecognized prior service costs (26) (28) Unrecognized net gain (27,728) (15,940) ________ ________ Accrued pension liability $(3,336) $(3,841) ________ ________ ________ ________ During fiscal 1994, the Company adopted an Excess Benefit Plan (EBP) that provides retirement benefits to executive officers and other key management staff. The EBP recognizes total compensation and service that would otherwise be disregarded due to Internal Revenue Code limitations on compensation in determining benefits under the regular retirement plan. The EBP is not funded and benefits are paid when due from general corporate assets. Note 5) Postretirement Benefits Other Than Pensions The Company provides certain health care and life insurance benefits to its retired Yankee Gas, YESCo, and RMS employees. On July 1, 1990, in accordance with terms of the divestiture, Yankee Gas began compensating the NU System for a portion of the NU System's liability for certain health care and life insurance expenses of retirees or surviving spouses. Yankee Gas and the NU System will share costs in a defined manner until June 30, 2005. The cost of providing those benefits for NU retirees was approximately $1,103,000 for the fiscal year ended September 30, 1997 and $1,104,000 and $1,070,000 for the comparable periods in 1996 and 1995, respectively. Yankee Gas has established two Internal Revenue Code Section 501(c)(9) Voluntary Employee Beneficiary Association (VEBA) Trusts, one for union employees and one for non-union employees, to fund its future liabilities for retiree health care and life insurance benefits. Contributions to the VEBA Trusts totaled $1.728 million for both fiscal 1997 and fiscal 1996. Assets of the VEBA Trusts are invested primarily in equity securities and investment grade bonds. The Company recognizes the cost of postretirement benefits over the employment period that encompasses eligibility to receive such benefits. The components of net postretirement benefits costs were: Years Ended September 30, 1997 1996 (Thousands of Dollars) Service cost $ 913 $ 937 Interest cost 1,685 1,644 Net transition amortization 875 875 Net other deferrals 1,055 (28) Less: Return on assets 1,646 729 ______ ______ Net postretirement benefits costs $2,882 $2,699 ______ ______ ______ ______ For Yankee Gas, the DPUC is allowing $1.728 million of associated expenses to be recovered in rates and up to an additional $1.5 million annually which is being collected through the rate settlement process further described under Note 9, as part of the DPUC re-opened Docket No. 92-02-19. For calculating the plan's year-end funded status, as well as the ensuing year's postretirement benefits costs, the following assumptions were used: Years Ended September 30, 1997 1996 Discount rate 7.50% 7.75% Expected long-term rate of return 9.00% 9.00% Health care cost trend rate - First year 8.00% 9.00% - Ultimate 5.00% 5.00% Trend rates are assumed to decrease one percent per year until they reach the ultimate rate. A one percent increase in the weighted average trend rate assumption of health care claims would result in a 16 percent increase in accumulated benefit obligations and a 35 percent increase in net periodic postretirement benefits costs. The following table represents the postretirement benefit plan's funded status reconciled to the consolidated balance sheets: At September 30, 1997 1996 (Thousands of Dollars) Accumulated benefit obligation $21,803 $22,156 Less: Market value of assets 10,790 6,613 ______ ______ Accumulated benefit obligation (greater than) plan assets (11,013) (15,543) Unrecognized transition amount 13,607 14,483 Unrecognized net gain (6,730) (3,597) ______ ______ Accrued postretirement benefit liability $(4,136) $(4,657) ________ ________ ________ ________ Note 6) Stock-Based Compensation Yankee Energy established Long-term Incentive Compensation Plans, in 1991 and 1996. Options on 65,600 shares of common stock were granted under the 1991 plan and options on 63,800 shares of common stock were granted under the 1996 plan. Under the terms of the options granted, the exercise price of any option may not be less than 100 percent of the fair market value of the common stock on the date of grant. The stock options vest over a five year period, with 20 percent becoming exercisable on each of the first five anniversaries of the grant. All stock options expire ten years from the date of grant. The Company accounts for stock options in accordance with Accounting Principles Board Opinion No. 25, under which no compensation costs have been recognized for stock option awards. Had compensation costs of option awards been determined under a fair value alternative method as stated in Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation", the Company would have been required to value such options and record such amount in the financial statements as compensation expense. Proforma net income and net income per share for fiscal 1997 and fiscal 1996 would have been $16,919,000 and $1.62 and $21,881,000 and $2.10, respectively. Yankee Gas arrived at the fair value of the stock grants at the date of the grant by using the Black Scholes option pricing model with the following weighted average assumptions: risk-free interest rate of 5.375 percent, expected life of 5.0 years, expected volatility of 18.0 percent and a dividend yield of 5.7 percent. The following summarizes stock option transactions for the fiscal years ended September 30, 1997 and 1996: Weighted Number Option Prices Average Price of Shares Outstanding Options September 30, 1995 $21.375-$21.63 $21.59 61,120 Granted $23.69 $23.69 63,800 Exercised $21.63 $21.63 (820) Canceled $21.63 -$23.69 $21.92 (9,100) ______ Outstanding Options September 30, 1996 $21.375-$23.69 $22.73 115,000 Exercised $21.63 -$23.69 $21.73 (4,860) Canceled $21.63 -$23.69 $22.97 (8,980) _______ Outstanding Options September 30, 1997 $21.375-$23.69 $22.75 101,160 At September 30, 1997 and 1996 there were exercisable 38,136 options and 21,000 options, respectively, which have weighted average exercise prices of $22.20 per share and $21.58 per share, respectively. Note 7) Short-Term Debt Yankee Gas has arranged a $60 million revolving line of credit with a group of four banks whereby funds may be borrowed on a short-term revolving basis using either fixed or variable rate loans. Yankee Gas also has an additional $27 million of credit lines available on an uncommitted basis. Yankee Gas had $36.3 million and $20.3 million outstanding under its agreements at September 30, 1997 and 1996, respectively. In addition, Yankee Energy had $2.7 million outstanding at September 30, 1997 and no amounts outstanding at September 30, 1996 on a $15 million line of credit. The weighted average interest rates on short-term debt at September 30, 1997 and 1996 were 6.0 percent and 5.6 percent, respectively. Note 8) Fair Value of Financial Instruments The following methods and assumptions were used to estimate the fair value of each of the following financial instruments: Cash and Temporary Cash Investments: The carrying amount approximates fair value. First Mortgage Bonds: The fair value of the Company's fixed rate long-term debt is based upon borrowing rates currently available to the Company. Adjustable rate securities are assumed to have a fair value equal to their carrying value. The carrying amount of the Company's financial instruments and the estimated fair value at September 30, 1997 and 1996 are as follows: September 30, 1997 1996 Carrying Estimated Carrying Estimated Amount Fair Value Amount Fair Value (Thousands of Dollars) First mortgage bonds $132,532 $142,896 $135,899 $146,663 ________ ________ ________ ________ The fair values shown above have been reported to meet the disclosure requirements of Statement of Financial Accounting Standards No. 107, "Disclosures About Fair Values of Financial Instruments," and do not purport to represent the amounts at which those obligations would be settled. Note 9) Commitments and Contingencies Construction Program: The Company's estimated capital expenditures for the fiscal years 1998 through 2002 are $194 million, including $55 million for fiscal 1998. The Company intends to use $140 million over this period, including $39 million for fiscal 1998, of these estimated expenditures to maintain the reliability of the distribution system and in projects that will generate or support gas sales and transportation activities, including the installation of a new customer information system. The remaining $54 million, including $15 million for fiscal 1998, is expected to be invested in energy related projects and businesses. Environmental Matters: Fourteen sites containing coal tar became the property of Yankee Gas at divestiture from Northeast Utilities. Contamination at these sites was caused by operations of former manufactured gas plants at those locations. Yankee Gas has reported the results of its environmental studies to the Connecticut Department of Environmental Protection (DEP). The DEP has not required that any remedial action be undertaken to date. However, of the fourteen, eight sites are presently listed on the Connecticut Inventory of Hazardous Waste Sites. Inclusion of a site on this list indicates that remediation may be required in the future. Remediation has been conducted at three of these properties. In addition, Yankee Gas has developed a cost estimate for the remaining sites based on various factors including the probability of clean-up. As a result of this effort, Yankee Gas recorded a liability of $35 million in fiscal 1993 for future environmental clean-up. Recovery of remediation costs has been specifically allowed by Yankee Gas' 1992 rate case decision. Presently, $325,000 is allowed annually in rates. If costs are expected to exceed $2.5 million on an annual basis, Yankee Gas is required to go to the DPUC for review. The DPUC has stated that "to the extent that coal tar remediation expenses are prudently incurred, they should be allowed as proper operating expenses." Yankee Gas has received funds 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. The terms of the aforementioned settlements are subject to confidentiality provisions in agreements between Yankee Gas and its insurance carriers. The proceeds are being reflected as reductions in the regulatory asset associated with recoverable environmental clean-up costs, as shown in the accompanying balance sheets. Transition Costs-Order No. 636: On April 8, 1992, the FERC issued Order No. 636 on pipeline restructuring. In essence, the FERC found that absent the unbundling of traditional merchant services, pipelines would not be able to achieve the FERC's long- term goal of open access and provide transportation services that are indifferent to the seller of the gas. Order No. 636, therefore, required all pipelines to implement restructuring of their services by the winter of 1993-94. The three major pipeline systems serving Yankee Gas (Iroquois, Tennessee Gas Pipeline Company and Algonquin Gas Transmission Company and its affiliate, Texas Eastern Transmission Company), have all restructured pursuant to the FERC directive. Yankee Gas has concurrently replaced the gas supply traditionally obtained from the pipeline companies' merchant services with firm purchases directly from producers and/or marketing companies. Yankee Gas present annual capacity commitment is approximately $82.7 million. Order No. 636 acknowledges that the restructuring of the pipelines' traditional services will cause pipelines to incur transition costs in several areas and provides mechanisms for the pipelines to fully recover prudently incurred transition costs attributable to the implementation of Order No. 636. On July 8, 1994, the DPUC issued a decision on the implementation of FERC Order No. 636 by the Connecticut Local Distribution Companies (LDCs). The DPUC is allowing the LDCs to offset the transition costs billed by pipelines under Order No. 636 with recoveries from capacity release activity, refunds of deferred gas costs for the 1992-93 period and all subsequent annual deferred gas costs, gas supplier refunds, off-system sales margin and interruptible margin earned in excess of target amounts. Through September 30, 1997, Yankee Gas has paid approximately $19.5 million of transition costs and an additional $3.5 million are anticipated. To date, Yankee Gas has collected $44.2 million through a combination of credits received from gas supplier refunds, deferred gas costs, excess interruptible margin, off- system sales margin, and capacity release agreements. On January 3, 1996, the DPUC issued a Final Decision in reopened Docket No. 92-02-19. The Docket allows for recovery of certain deferred regulatory assets with the stipulation that Yankee Gas would not increase its rates before October 1, 1998, except in the event of certain circumstances which would adversely affect Yankee Gas' financial condition. Yankee Gas may apply a portion of excess transition credits received from pipeline refunds, interruptible excess margin, deferred gas costs, capacity release activity, and off-system sales margin to certain regulatory assets. As of September 30, 1997, excess collections of approximately $24.7 million were applied against the deferred regulatory assets specified in the decision. Firm Transportation: On August 2, 1995, the DPUC issued a Final Decision in Docket No. 94-11-12, DPUC Review of Connecticut Local Distribution Companies' Cost of Service Study Methodologies. The docket was intended to investigate the issues surrounding the development of firm transportation (FT) rates at the state level in response to FERC Order No. 636. The Decision provides guidelines for the development of FT rates to be offered by the State's three LDCs, one of which is Yankee Gas. On January 24, 1996, the DPUC issued a Final Decision on Docket No. 92-02-19 Reopen I. This decision enabled Yankee Gas to implement FT rates and services as contemplated in the August 2, 1995 decision referenced above. The Decision allows Yankee Gas to offer a broad array of service options to commercial and industrial FT customers. Yankee Gas implemented these new FT rates and services on April 1, 1996, and as of September 30, 1997 had approximately 1,460 customers under the new FT service. A switch by existing sales customers to transportation tariffs will result in decreased revenues for Yankee Gas as the portion of revenues representing gas costs will now be borne directly by those customers. 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. This Decision did not address Yankee Gas' revenue requirement; Yankee Gas has maintained the existing margin recovery and rates of return established in the last rate case decision issued for Yankee Gas in 1992. Rate Review: On August 25, 1996, Yankee Gas filed an application with the DPUC for a Financial and Operational Review (Review). This Review was required under Connecticut statute since Yankee Gas had not undergone a rate proceeding within the last four years. Yankee Gas' last rate application was approved on August 26, 1992, and this Review was necessary to comply with the statute. On July 9, 1997, the DPUC issued its decision in Docket No. 96-08-05. The DPUC decision, which is not a rate order, called for a lowering of Yankee Gas' authorized Return on Equity (ROE) from 12.43 percent to 11.15 percent. The DPUC believed that lower current interest rates and recently allowed rates of return for other Connecticut utilities justified a lower ROE for Yankee Gas. On October 1, 1997, the DPUC approved a settlement whereby Yankee Gas will credit approximately $3.2 million to firm sales customers through the PGA during the period November 1997 through March 1998. The settlement also allows Yankee Gas to maintain its base rates until the end of fiscal year 2000, resulting in an eight-year period in which Yankee Gas will have gone without an increase in its base rates. Gas Supply Hedging Activities: Yankee Gas has gas service agreements with two customers to supply gas at fixed prices. Because Yankee Gas purchases gas on a variable price basis, it has found it necessary to hedge gas prices with derivatives to respond to customers' needs for fixed pricing. Both agreements are similar in structure in that Yankee Gas executed a commodity swap contract with a commodity trading firm. Under a master commodity swap agreement, the price of a specified quantity of gas is fixed over the term of the gas service agreement with the customer. In both cases, Yankee Gas is acting as an agent using its credit to provide fixed pricing to its customers using a commodity swap. Yankee Gas' results of operations are unaffected by the hedge transaction given that it passes through the cost of the hedge to either the commodity trading firm or its customer depending on the difference in the fixed and floating prices for gas. Also, the customers are accountable for all costs incurred by Yankee Gas to execute and maintain the commodity swap contract. Of the two gas service hedging agreements currently in force, only one is material relative to the significance of gas volumes being hedged. This agreement has a ten-year term and requires Yankee Gas to supply approximately one BCF of gas per year, with relatively low margin, at a fixed price beginning August 1, 1995. The price is allowed to escalate by a predetermined rate every year after the first year. The commodity swap contract for this hedging agreement was executed August 17, 1994. Yankee Gas is responsible for margin calls collateralizing the commodity swap contract from August 17, 1994 through the term of the gas service agreement. Currently, Yankee Gas has a letter of credit in the amount of $2.0 million issued to the commodity trading firm collateralizing the commodity contract. Tax/Legal Issues: 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 approximately $5.0 million for 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 accepted by the City. Yankee Gas is currently in the process of litigating this retroactive reassessment. Although it is anticipated that the outcome of this 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. In November 1995, a class action suit was filed against Yankee Gas and the state's two other LDCs by the Connecticut Heating and Cooling Contractors' Association, Inc., claiming the LDCs engaged in unfair trade practices. The action alleges that the LDCs unfairly competed with licensed plumbers and contractors by performing customer service work using customer service employees who did not possess state trade licenses. 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, on a going-forward basis, a separate procedure for state certification of gas service employees. While the ultimate results of the class action suit cannot be determined, management does not expect that it will have a material adverse effect on the Company's consolidated results of operations or financial position.
