YANKEE ENERGY SYSTEM, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 1)	GENERAL The accompanying unaudited consolidated financial statements should be read in conjunction with the Annual Report of Yankee Energy System, Inc. (the Company) on Form 10-K for the fiscal year ended September 30, 1998 (1998 Form 10-K), including the audited financial statements (and notes thereto) incorporated by reference therein and the Company's quarterly report on Form 10-Q for the quarter ended December 31, 1998. In the opinion of the Company, the accompanying unaudited consolidated financial statements contain all adjustments (consisting only of normal recurring accruals) necessary to present fairly the financial position of the Company as of March 31, 1999, and its results of operations for the three and six months ended March 31, 1999 and 1998 and cash flows for the six months ended March 31, 1999 and 1998. The results of operations for the three and six months ended March 31, 1999 and 1998 are not necessarily indicative of the results expected for a full year, due mainly to the highly seasonal nature of the gas business. 2)	ACCOUNTING FOR THE EFFECTS OF REGULATION The Company's wholly-owned subsidiary, Yankee Gas Services Company (Yankee Gas), is subject to regulation by the Connecticut Department of Public Utility Control (DPUC). The Company prepares its financial statements in accordance with generally accepted accounting principles which includes 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, Yankee Gas 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 benefit costs. The specific amounts related to these items are disclosed in the consolidated balance sheets. For additional information about these items see the 1998 Form 10-K. Yankee Gas continues to be subject to cost-of-service based rate regulation by the DPUC. Based upon current regulation and recent regulatory decisions, Yankee Gas believes that its use of regulatory accounting in accordance with the provisions of FAS 71 is appropriate and its regulatory assets are probable of recovery. 3) 	EARNINGS PER SHARE The Company computes and presents basic and diluted earnings per share. The basic weighted average shares outstanding for the three months ended March 31, 1999 and 1998 were 10,608,406 and 10,483,265, respectively, and for the six months ended March 31, 1999 and 1998 were 10,587,947 and 10,472,510, respectively. The diluted weighted average shares outstanding for the three months ended March 31, 1999 and 1998 were 10,616,244 and 10,492,271, respectively, and for the six months ended March 31, 1999 and 1998 were 10,601,952 and 10,479,491, respectively. As such, there is no difference between basic and diluted earnings per share. 4) 	COMMITMENTS AND CONTINGENCIES The Company faces a number of contingencies which arise during the normal course of business and which have been discussed in Note 9 (entitled "Commitments and Contingencies") to the Consolidated Financial Statements included in the Company's 1998 Form 10-K Report. Except as disclosed below, for the six months ended March 31, 1999, there have been no material changes in the matters discussed in Note 9 to the Company's 1998 Form 10-K Report. YESCo Power Division: The Company's wholly-owned subsidiary, Yankee Energy Services Company (YESCo), is currently negotiating the sale of its more significant Power division investments with several interested parties. These investments include an operating land fill gas (LFG) fueled generating facility in Brookhaven, NY, interests in two operating cogeneration facilities, development stage projects and other less significant assets. The total investment at March 31, 1999 is approximately $15.5 million. Management expects that the sale of the Power division assets will have no material effect on the Company's consolidated balance sheets. One of Yankee Gas' largest customers was the Foxwoods Hotel and Casino (Foxwoods) operated by the Mashantucket Pequot Indian Tribe (Pequots). The City of Norwich, Connecticut, pursuant to an agreement with the Pequots, became the sole provider of gas transportation service to the Pequots. Yankee Gas has made a claim against the Pequots for payment for distribution facilities, which Yankee Gas constructed pursuant to agreement with the Pequots, which claim seeks to compensate Yankee Gas for its investment. Yankee Gas has on- reservation distribution facilities totaling approximately $0.4 million and off-reservation distribution facilities totaling approximately $4.9 million. Yankee Gas is evaluating the Pequots' response to the claim in an effort to resolve the dispute consensually before any legal action is taken. 5)	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 Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. When used in this report, the words "anticipate," "plan," "believe," "estimate," "expect," and similar expressions as they relate to the Company or its management are intended to identify forward-looking statements. All forward-looking statements involve risks and uncertainties. Actual results may differ materially from those discussed in, or implied by, the 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, certain environmental matters and internal and/or third party delays or failures in achieving Year 2000 compliance, as well as such other factors as set forth in the Company's Form 10-K for the year ended September 30, 1998 and in other filings with the Securities and Exchange Commission. 6)	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. 7)	RECLASSIFICATIONS Certain prior year amounts have been reclassified to conform with current year presentation. REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Board of Directors and Shareholders of Yankee Energy System, Inc.: We have reviewed the accompanying consolidated balance sheet of Yankee Energy System, Inc. (a Connecticut corporation) and subsidiaries (the Company) as of March 31, 1999, and the related consolidated statements of income for the three- and six-month period then ended and cash flows for the six-month period then ended. These financial statements are the responsibility of the Company's management. We conducted our review in accordance with standards established by the American Institute of Certified Public Accountants. A review of interim financial information consists principally of applying analytical procedures to financial data and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with generally accepted auditing standards, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion. Based on our review, we are not aware of any material modifications that should be made to the financial statements referred to above for them to be in conformity with generally accepted accounting principles. We have previously audited, in accordance with generally accepted auditing standards, the consolidated balance sheet of Yankee Energy System, Inc. as of September 30, 1998 (not presented herein), and, in our report dated November 16, 1998, we expressed an unqualified opinion on that statement. In our opinion, the information set forth in the accompanying consolidated balance sheet as of September 30, 1998 is fairly stated, in all material respects, in relation to the balance sheet from which it has been derived. 	 Arthur Andersen LLP Hartford, Connecticut April 26, 1999 ITEM 2.	Management's Discussion and Analysis of Financial Condition and Results of Operations RESULTS OF OPERATIONS Consolidated net income was $11.5 million for the three months ended March 31, 1999, compared to $10.8 million for the same period a year earlier. The corresponding basic and diluted earnings per share were $1.08 and $1.03 for the three months ended March 31, 1999 and 1998, respectively. Earnings for the second quarter of fiscal year 1999 increased approximately five percent due to weather that was 15 percent colder than the same period last year. Operating income increased 14 percent over the same period last year, partially offset by an increase in income taxes due to a higher effective tax rate. This quarter's overall earnings were negatively impacted by two items. First, weather again played a role by virtue of a seven percent warmer-than-normal quarter. Management estimates that warmer weather reduced earnings by $1.4 million, or $0.13 per share. The prior year's quarter experienced even warmer than normal weather with management estimating a weather- related reduction to earnings of $3.9 million, or $0.38 per share. Second, a metering problem with an industrial customer resulted in approximately $0.4 million in lost margin during the second quarter. The prior year's quarter was also negatively impacted by customer bill credits of $0.9 million, or $0.09 per share, as part of a rate review settlement reached with the Connecticut Department of Public Utility Control. A favorable impact to this quarter's results was the continuing operations from nonutility subsidiaries, which performed at a break even level. The recent financial performance at Yankee Energy Services Company (YESCo) reflects the cost reduction initiatives that have now been fully implemented. R. M. Services (RMS), our receivables management company, again positively contributed to quarterly results. As a result of continuing growth for its collection services, RMS is completing a new call center in East Hartford, Connecticut, which is expected to be operational in the third quarter. COMPARISON OF THE SECOND QUARTER OF FISCAL 1999 WITH THE SECOND QUARTER OF FISCAL 1998 OPERATING REVENUES Utility revenues increased $4.5 million, or 4 percent, in the second quarter of fiscal 1999 compared with the same period in the prior fiscal year. This increase was partially offset by a $0.3 million decrease in operating revenues from nonutility operations. The components of the change in operating revenues are as follows: Three Months Ended March 31, Increase/ 1999 1998 (Decrease) (In thousands) Firm sales $ 94,766 $ 92,853 $ 1,913 Firm transportation 8,801 5,419 3,382 Interruptible/off-system sales 4,923 5,409 (486) Interruptible transportation 700 943 (243) Other utility revenues 1,681 1,701 (20) _______ _______ _______ Total Utility revenues 110,871 106,325 4,546 Nonutility revenues 6,573 6,868 (295) _______ _______ _______ Total operating revenues $117,444 $113,193 $ 4,251 _______ _______ _______ _______ _______ _______ The corresponding changes in Yankee Gas' throughput were as follows: Three Months Ended March 31, Increase/ (Mcf - thousands) 1999 1998 (Decrease) Firm sales 10,229 9,902 327 Firm transportation 4,116 3,008 1,108 Interruptible/ off-system sales 1,468 1,228 240 Interruptible transportation 955 1,889 (934) _______ ______ _____ Total throughput 16,768 16,027 741 _______ ______ _____ _______ ______ _____ The change in utility revenues was due primarily to weather that was 15 percent colder than the prior year. The colder weather in the second quarter of the fiscal 1999 heating season directly increased sales to firm sales customers. However, this increase was partially offset by interruptible customers switching to alternative fuels as a result of continued lower oil prices. The slight decrease in nonutility revenues in the second quarter of fiscal 1999 compared to the same period in fiscal 1998 is primarily due to the reorganization of YESCo's operations, offset by an increase in RMS' revenues due to expansion of its collection business. OPERATING EXPENSES Total operating expenses increased $1.0 million in the second quarter of fiscal 1999 compared to the same period in the prior year as a result of the following items: - -	Cost of gas decreased $1.3 million, or 2 percent, for the three months ended March 31, 1999 compared to the three months ended March 31, 1998 due primarily to the continued shift of customers to transportation service, partially offset by an increase in costs due to additional firm sales. - -	Cost of goods sold increased slightly in the second quarter of fiscal 1999 compared to the second quarter of fiscal 1998 due to increased nonutility activity resulting primarily from an expansion of RMS'collection business, partially offset by the corresponding decrease in YESCo's revenues due to management's reorganization of YESCo. - -	Operations and maintenance expenses increased $1.5 million, primarily due to increases in Yankee Gas expenses for pension, uncollectible accounts, and data center operations. These increases were offset by a slight decrease in nonutility expenses due to cost reduction initiatives implemented by YESCo. - -	Depreciation and amortization expense increased $0.2 million, primarily due to additions in plant, property and investments. - -	Taxes other than income taxes increased $0.6 million, primarily due to higher Connecticut gross earnings taxes as a result of the increase in revenues. INTEREST EXPENSE Interest expense decreased $0.2 million primarily due to lower short-term debt outstanding. This decrease was partially offset by an increase in long-term debt interest expense, primarily due to a $50 million new long-term debt financing completed in January 1999. INCOME TAXES Federal and state income taxes increased $2.6 million primarily due to higher pre-tax income and a higher effective tax rate for the three months ended March 31, 1999 compared to the three months ended March 31, 1998. The second quarter effective tax rate reflects a retroactive adjustment to the effective tax rate for the six months ended March 31, 1999. COMPARISON OF THE FIRST SIX MONTHS OF FISCAL 1999 WITH THE FIRST SIX MONTHS OF FISCAL 1998 OPERATING REVENUES Utility revenues decreased $15.4 million, or 8 percent, in the first six months of fiscal 1999 compared with the same period in the prior fiscal year. This decrease was offset by a $2.0 million increase in operating revenues from nonutility operations. The components of the change in operating revenues are as follows: 	 Six Months Ended March 31, Increase/ 1999 1998 (Decrease) (In thousands) Firm sales $158,596 $175,358 $(16,762) Firm transportation 15,799 9,938 5,861 Interruptible/off-system sales 9,613 13,459 (3,846) Interruptible transportation 1,605 1,488 117 Other utility revenues 2,440 3,200 (760) _______ _______ _______ Total utility revenues 188,053 203,443 (15,390) Nonutility revenues 14,392 12,345 2,047 _______ _______ _______ Total operating revenues $202,445 $215,788 $(13,343) _______ _______ _______ _______ _______ _______ The corresponding changes in Yankee Gas' throughput were as follows: Six Months Ended March 31, Increase/ (Mcf - thousands) 1999 1998 (Decrease) Firm sales 17,322 19,254 (1,932) Firm transportation 7,298 5,257 2,041 Interruptible/ off-system sales 2,801 2,994 (193) Interruptible transportation 2,329 3,216 (887) ______ ______ ______ Total throughput 29,750 30,721 (971) ______ ______ ______ ______ ______ ______ The change in utility revenues was due to a combination of items directly related to warmer than normal weather experienced over the past two heating seasons. Firm sales continue to decrease as an increasing number of commercial and industrial customers continued to shift from gas sales to transportation service resulting in a decrease in utility revenues. The switch to transportation has no effect on margin because the cost of gas has traditionally been a pass through item. Interruptible revenues decreased primarily as a result of lower oil prices in the first six months of fiscal 1999 compared to the same period in the prior year, which enabled these customers to use a less costly alternative fuel. These decreases were partially offset by an increase in nonutility revenues in the second quarter of fiscal 1999 compared to the same period in fiscal 1998. This increase was primarily due to an increase in R.M. Services' revenues due to expansion of its collection business, offset by a slight decrease in YESCo's revenues due to management's reorganization of YESCo. OPERATING EXPENSES Total operating expenses decreased $12.3 million in the first six months of fiscal 1999 compared with the same period in the prior year as a result of the following items: - -	Cost of gas decreased $16.6 million, or 15 percent, for the six months ended March 31, 1999 compared to the six months ended March 31, 1998 due primarily to the weather impact on firm sales customers and the continued increase in transportation customers. - -	Cost of goods sold increased $1.8 million in the first six months of fiscal 1999 compared to the first six months of fiscal 1998 due to expansion of R.M. Services' collection business, partially offset by the corresponding decrease in YESCo's revenues due to management's reorganization of YESCo. - -	Operations and maintenance expenses increased $1.2 million, primarily due to increases in data center operation expense, expenses related to nonutility activity, uncollectible expense and pension expenses. - -	Depreciation and amortization expense increased $0.6 million, primarily due to additions in plant, property and investments.	 	 - -	Taxes other than income taxes increased $0.8 million, primarily due to increases in Connecticut unemployment taxes and municipal taxes in fiscal 1999. INTEREST EXPENSE Interest expense increased $0.3 million mainly due to higher short-term debt outstanding during the six months ended March 31, 1999 and higher interest on long-term debt, primarily due to a $50 million new long-term debt financing completed in January 1999. INCOME TAXES Federal and state income taxes decreased $1.0 million primarily due to lower pre-tax income for the six months ended March 31, 1999 compared to the six months ended March 31, 1998, partially offset by a slight increase in the effective tax rate. LIQUIDITY AND CAPITAL RESOURCES Cash and temporary cash investments at March 31, 1999 totaled $11.0 million. Cash provided by operating activities was $38.9 million in the second quarter of fiscal 1999. The increase in cash provided by operating activities was primarily due to a decrease in working capital requirements. The Company also generated cash through financing activities, primarily by the issuance of new common stock and issuance of long-term debt. Cash from operating activities and financing activities was used primarily for repayments of short-term debt, dividend payments and capital expenditures in the first six months of fiscal 1999. Expenditures for investment in plant, property and investments totaled $13.8 million for the first six months of fiscal 1999. The seasonal nature of gas revenues, inventory purchases and construction expenditures creates a need for short-term borrowing to supplement internally generated funds. As of March 31, 1999, Yankee Gas had a revolving line of credit of $60 million with a group of four banks. Under the agreement, funds may be borrowed on a short-term revolving basis using either fixed or variable rate loans. Yankee Gas also had uncommitted credit lines of $20 million as of March 31, 1999. At March 31, 1999, Yankee Gas had no amounts outstanding under its agreements. Yankee Energy had $16.5 million outstanding at March 31, 1999 under its $25 million committed line of credit, which is used to fund development of the Company's nonutilty businesses. In January 1999, Yankee Gas completed a $50 million new long-term debt financing at 6.2 percent, for the purposes of replacing a portion of the existing outstanding short-term debt. Yankee Gas plans to redeem its Series A Tranche D First Mortgage Bonds in August 1999, with cash on hand and short-term debt available at that time. Series A Trance D First Mortgage Bonds become eligible for early redemption in August 1999. The long-term credit needs of Yankee Gas are being met by a first mortgage bond indenture which provides for the issuance of bonds from time to time, subject to certain issuance tests. At March 31, 1999, indenture requirements, including the required coverage ratio, would allow for the issuance of an additional $174 million of bonds at an assumed interest rate of 6.6 percent. Yankee Gas has entered into fixed revenue-rate contracts with two customers for the delivery of natural gas. Yankee Gas has hedged these commitments with the purchase of natural gas swaps. In order to satisfy certain provisions of the arrangement, Yankee Gas has provided a letter of credit for $1.75 million, as of March 31, 1999. The Company's 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. The Company entered into an interest rate swap transaction in February 1999. The $49,000,000 (notional amount) agreement had the effect of converting the interest obligations on Yankee Gas' $19,000,000, 10.07% Bonds and $30,000,000, 7.19% Bonds to variable rates. Under the agreement, the Company receives the stated fixed rate and pays a floating rate based on a "basket" of interest rate indices, as determined in six month intervals. Net receipts or payments under the agreement are recognized as adjustments to interest expense. YEAR 2000 The Company is currently implementing new information systems and enhancing existing information systems to address Year 2000 issues, which could have significant adverse effects on the Company if not properly resolved. In fiscal 1995, the Company began testing and remediation for Year 2000 problems and has assigned dedicated personnel to its Year 2000 project. Remediated programs are being tested prior to being declared compliant. As of March 31, 1999, YES has completed the inventory and the assessment of risk phases of the Year 2000 project for all mainframe systems. The Company is currently in the remediation and testing phases. As part of the process, a detailed inventory of all hardware and software currently utilized by the Company has been prepared, and a timetable has been established to ensure testing of all applications. The scope of the assessment phase also included the Company's interface systems with significant suppliers, government agencies and other third parties. However, there can be no guarantee that the systems of these third parties will be converted on a timely basis and will not have an adverse effect on the Company's operations or systems. All mainframe systems that are being remediated are now in the implementation phase, which as of March 31, 1999 was approximately 98 percent complete. In addition to remediating existing systems, the Company purchased a new human resource information system (HRIS) and a new customer service (CS) system. These systems were purchased to improve functionality of the application software and to improve efficiency and customer service. In addition, any Year 2000 issues associated with these systems will be eliminated. The new HRIS system became operational January 1, 1999 and the new CS system is expected to be operational in July 1999. For non-mainframe systems, the Company has developed a test environment to carry out the remainder of the remediation program. The inventory and risk assessment phase of all non- mainframe systems has been completed. The completion of the remediation/replacement and testing phases is expected by September 1999. As of March 31, 1999, the Company installed a new supervisory control and data acquisition system (SCADA system), which monitors gas flows and pressures within the gas distribution system. This eliminated any Year 2000 issues associated within that system. The Company currently estimates that total cost to update all of the Company's systems for Year 2000 compliance will be approximately $21.8 million, including approximately $0.6 million for the new HRIS system, $19.4 million for the new CS system and $1.3 million for the new SCADA system. All such costs associated with system enhancements have and will continue to be expensed as incurred and the costs of new systems will be capitalized as appropriate. As of March 31, 1999, the Company expensed approximately $0.5 million and capitalized approximately $19.0 million, of these costs. The remaining costs will be incurred during fiscal 1999. These costs have been financed through short-term borrowing and internally generated funds. The primary business risk associated with Year 2000 is the Company's ability to continue to transport and distribute gas to its customers without interruption. In the event the Company and/or its suppliers and vendors are unable to remediate the Year 2000 problem prior to January 1, 2000, operations of the Company could be significantly impacted. In order to mitigate this risk, the Company is developing contingency plans to continue operations through manual intervention and other procedures should it become necessary to do so. Such procedures are expected to include back-up power supply for its critical pipeline and storage operations and, if necessary, curtailment of supply. The Company expects to complete its operational contingency plans by the end of fiscal 1999. Although the Company expects its systems to be Year 2000 compliant on or before December 31, 1999, it cannot predict the outcome or the success of its Year 2000 program, or that the costs required to address the Year 2000 issue, or that the impact of a failure to achieve substantial Year 2000 compliance, will not have a material adverse effect on the Company's business, financial condition or results of operations. ITEM 3. Quantitative and Qualitative Disclosures About Market Risk Commodity Market Risk Yankee Gas is subject to market risk due to fluctuations in the price of natural gas. All of Yankee Gas' sales are designed to fully recover the cost of gas. Yankee Gas passes on to its firm customers changes in gas costs from those reflected in its tariffs under purchased gas adjustment provisions allowed by the Connecticut Department of Public Utility Control. Interruptible and off-system sales are priced competitively at not less than the cost of gas associated with those sales plus applicable taxes and margin. Yankee Gas has entered into fixed revenue-rate contracts with two customers for the delivery of natural gas. Yankee Gas has hedged these commitments with the purchase of natural gas swaps. In order to satisfy certain provisions of the arrangement, Yankee Gas has provided a letter of credit for $1.75 million, as of March 31, 1999. The Company's 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. Interest Rate Risk The Company entered into an interest rate swap transaction in February 1999. The $49,000,000 (notional amount) agreement had the effect of converting the interest obligations on Yankee Gas' $19,000,000, 10.07% Bonds and $30,000,000, 7.19% Bonds to variable rates. Under the agreement, the Company receives the stated fixed rate and pays a floating rate based on a "basket" of interest rate indices, as determined in six month intervals. Net receipts or payments under the agreement are recognized as adjustments to interest expense. The maximum exposure to the Company is $250,000 per year. In addition, both Yankee Energy and Yankee Gas have committed and uncommitted lines of credit with variable interest rates. PART 	II	OTHER INFORMATION Item 4.
