Accounting Policies Business, Utility Operations and Regulation The Company is an operating public utility engaged, together with its utility subsidiaries, principally in the generation, purchase, transmission, distribution and sale of electricity and in the purchase, transmission, distribution, sale and transportation of natural gas. The Company is subject to the jurisdiction of The Public Utilities Commission of the State of Colorado ("CPUC") with respect to its retail electric and gas operations and the Federal Energy Regulatory Commission ("FERC") with respect to its wholesale electric operations and accounting policies and practices. Approximately 90% of the Company's electric and gas revenues are subject to CPUC jurisdiction. Cheyenne Light, Fuel and Power Company ("Cheyenne") is subject to the jurisdiction of the Public Service Commission of Wyoming ("WPSC"). WestGas Interstate, Inc. ("WGI") and Texas-Ohio Pipeline, Inc. are subject to the jurisdiction of the FERC. The gas marketing, power brokering and other operations of e prime, inc. and Texas-Ohio Gas, Inc. (acquired September 1, 1996) are not regulated. The Company also intends to invest in electricity systems outside the United States as discussed in Note 5. The Company's international investments will be subject to regulation in the countries in which such investments are made. Regulatory Assets and Liabilities The Company and its regulated subsidiaries prepare their financial statements in accordance with the provisions of Statement of Financial Accounting Standards No. 71 - "Accounting for the Effects of Certain Types of Regulation" ("SFAS 71"). SFAS 71 recognizes that accounting for rate regulated enterprises should reflect the relationship of costs and revenues introduced by rate regulation. A regulated utility may defer recognition of a cost (a regulatory asset) or recognize an obligation (a regulatory liability) if it is probable that, through the ratemaking process, there will be a corresponding increase or decrease in revenues. On January 1, 1996, the Company adopted Statement of Financial Accounting Standards No. 121 "Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of" which imposes stricter criteria for the continued recognition of regulatory assets on the balance sheet by requiring that such assets be probable of future recovery at each balance sheet date. The adoption of this statement did not have a material impact on the Company's results of operations, financial position or cash flows. The following regulatory assets are reflected in the Company's consolidated condensed balance sheets: 5 NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued) March 31, December 31, Recovery 1997 1996 Through ---- ---- ------- (Thousands of Dollars) Nuclear decommissioning costs, net (Note 2) $ 81,474 $ 89,731 2005 Income taxes ............................. 94,756 98,355 2006 Employees' postretirement benefits other than pensions..................... 55,836 54,449 2013 Early retirement costs.................... 13,290 15,505 1998 Employees' postemployment benefits........ 24,700 24,797 Undetermined Demand-side management costs.............. 42,416 41,462 2002 Unamortized debt reacquisition costs...... 19,408 19,914 2024 Other..................................... 3,904 4,353 1999 ----- ----- Total................................... 335,784 348,566 Classified as current..................... 44,020 44,110 ------ ------ Classified as noncurrent.................. $291,764 $304,456 ======== ======== The regulatory assets of the Company and its regulated subsidiaries as of March 31, 1997, are reflected in rates charged to customers over the recovery periods noted above. The Company believes it will continue to be subject to rate regulation to the extent necessary to recover these assets. In the event that a portion of the Company's operations is no longer subject to the provisions of SFAS 71 as a result of a change in regulation or the effects of competition, the Company could be required to write-off related regulatory assets, determine any impairment to other assets resulting from deregulation and write-down any impaired assets to their estimated fair value. On January 27, 1997, the CPUC issued its order on the Company's 1996 gas rate case. The CPUC allowed recovery of postemployment benefit costs associated with its gas operations on an accrual basis under Statement of Financial Accounting Standards No. 112 - "Employers' Accounting for Postemployment Benefits" ("SFAS 112") and denied amortization of the approximately $8.7 million regulatory asset recognized upon the adoption of SFAS 112. The Company intends to appeal the decision related to this issue and is assessing the impact of this decision on the future recovery of the electric jurisdictional portion of postemployment benefit costs totaling approximately $13.8 million. The Company believes that it will be successful on appeal and that the associated regulatory asset is realizable. If the appeal is unsuccessful, these amounts will be written off. Recovered/Recoverable Purchased Gas and Electric Energy Costs - Net The Company's and Cheyenne's tariffs contain clauses which allow recovery of certain purchased gas and electric energy costs in excess of the level of such costs included in base rates. Currently, these cost adjustment tariffs are revised periodically, as prescribed by the appropriate regulatory agencies, for any difference between the total amount collected under the clauses and the recoverable costs incurred. The cumulative effects are recognized as a current asset or liability until adjusted by refunds or collections through future billings to customers. The CPUC order related to the Company's merger rate filing modified and replaced the Company's Energy Cost Adjustment ("ECA") with an Incentive Cost Adjustment ("ICA"), which allows for a 50%/50% sharing of certain fuel and energy cost increases or decreases among customers and shareholders. As of March 31, 1997, the change did not impact cost recoveries. Other Property Property, plant and equipment includes approximately $18.4 million and $25.4 million, respectively, for costs associated with the engineering design of a planned future Pawnee 2 generating station and certain water 6 NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued) rights located in southeastern Colorado, also obtained for a future generating station. The Company is earning a return on these investments based on the Company's weighted average cost of debt and preferred stock in accordance with a CPUC rate order. Miscellaneous Income and Deductions - net Miscellaneous income and deductions - net includes items which are non-operating in nature or, in general, are not considered in the ratemaking process. Such items include, among other things, Merger related costs (see Note 3), contributions, gains and losses on the sale of property and certain litigation, severance and other accruals. Individually, these amounts did not have a material impact on the Company's results of operations. Statements of Cash Flows - Non-cash Transactions Shares of common stock (250,058 in 1997 and 274,934 in 1996), valued at the market price on date of issuance (approximately $10 million in 1997 and 1996), were issued to the Employees' Savings and Stock Ownership Plan of Public Service Company of Colorado and Participating Subsidiary Companies. The estimated issuance values were recognized in other operating expenses during the respective preceding years. Shares of common stock (6,470 in 1996), valued at the market price on the date of issuance ($0.2 million in 1996), were issued to certain executives pursuant to the applicable provisions of the executive compensation plans. The stock issuances referenced above were non-cash financing activities and are not reflected in the consolidated condensed statements of cash flows. General See Note 1. of the Notes to Consolidated Financial Statements in the Company's 1996 Annual Report on Form 10-K for a summary of the Company's significant accounting policies. Certain prior year amounts have been reclassified to conform to the current year's presentation. 2. Fort St. Vrain In 1989, the Company announced its decision to end nuclear operations at the Fort St. Vrain Nuclear Generating Station ("Fort St. Vrain") and to proceed with the defueling and decommissioning of the reactor. While the defueling of the reactor to the Independent Spent Fuel Storage Facility ("ISFSI") was completed in June 1992, several issues related to the ultimate storage/disposal of Fort St. Vrain's spent nuclear fuel remained unresolved. On February 9, 1996, the Company and the Department of Energy ("DOE") entered into an agreement resolving all the defueling issues. As part of this agreement, the Company has agreed to the following: 1) the DOE assumed title to the fuel currently stored in the ISFSI, 2) the DOE will assume title to the ISFSI and will be responsible for the future defueling and decommissioning of the facility, 3) the DOE agreed to pay the Company $16 million for the settlement of claims associated with the ISFSI, 4) ISFSI operating and maintenance costs, including licensing fees and other regulatory costs, will be the responsibility of the DOE, and 5) the Company provided to the DOE a full and complete release of claims against the DOE resolving all contractual disputes related to storage/disposal of Fort St. Vrain spent nuclear fuel. On December 17, 1996, the DOE submitted a request to the Nuclear Regulatory Commission ("NRC") to transfer the title of the ISFSI. This request is being reviewed by the NRC and the Company anticipates approval in mid-1997. On March 22, 1996, the Company and the decommissioning contractors announced that the physical decommissioning activities at the facility have been completed. The final site survey was completed in late October 1996. NRC site release activities are continuing. The Company requested the NRC to terminate the Part 50 license and 7 NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued) it is anticipated that the license will be terminated by mid-1997. Under the Price-Anderson Act, the Company remains subject to potential assessments levied in response to any nuclear incidents prior to early 1994, as disclosed in the Company's 1996 Annual Report on Form 10-K. At March 31, 1997, a remaining $7.9 million defueling and decommissioning liability was reflected on the consolidated condensed balance sheet. The Company believes this remaining decommissioning liability is adequate to complete all final decommissioning activities. As a result of the DOE settlement, coupled with a complete review of expected remaining decommissioning costs and establishment of the anticipated refund to customers, pre-tax earnings for the first quarter of 1996 were positively impacted by approximately $16 million. In accordance with the 1991 CPUC approval to recover certain decommissioning costs, 50% of any cash amounts received from the DOE as part of a settlement, net of costs incurred by the Company, including legal fees, is to be refunded or credited to customers. The Company established an $8 million refund liability in the first quarter of 1996. In early 1997, such obligation was reduced by approximately $1.1 million after amounts to be refunded were finally determined and approved by the CPUC. Such amounts will be refunded over a three year period. 3. Merger In August 1995, the Company, Southwestern Public Service Company ("SPS"), a New Mexico corporation, and New Century Energies, Inc. ("NCE"), a Delaware corporation, entered into an Agreement and Plan of Reorganization ("Merger Agreement") providing for a business combination as peer firms involving the Company and SPS in a "merger of equals" transaction (the "Merger"). Based on the outstanding common stock of the Company and SPS at March 31, 1997, the Merger would result in the common shareholders of the Company owning 63% of the common equity of NCE and the common shareholders of SPS owning 37% of the common equity of NCE. All required State and Federal regulatory agency authorizations have been received, except for the approval by the Securities and Exchange Commission ("SEC"). The Company expects that the SEC will make its ruling on the Merger in the very near term. It is currently expected that the Merger will be completed in the second quarter of 1997. It is management's intention that NCE begin realizing certain savings upon the consummation of the Merger and, accordingly, costs associated with the Merger and the transition planning and implementation are expected to negatively impact earnings during 1997. The Company recognized approximately $1.3 and $2.8 million of costs associated with the Merger during the first three months of 1997 and 1996, respectively. The Merger is expected to qualify as a tax-free reorganization and as a pooling of interests for accounting purposes. 4. Commitments and Contingencies Regulatory Matters 1995 Merger Rate Filings In connection with the Merger with SPS, in November 1995, the Company filed comprehensive proposals with the CPUC, the WPSC and the FERC to obtain approval of such Merger and the associated comprehensive proposals from such regulatory agencies. On November 29, 1996, and as modified on January 15, 1997, the CPUC issued a written decision approving the Merger as well as the major provisions of a stipulation and agreement entered into among the Company, the CPUC Staff, the Colorado Office of Consumer Counsel ("OCC"), and substantially all other parties. The decision establishes a five year performance based regulatory plan and acknowledges that the Merger is in the public interest. The major provisions of the decision include: 8 NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued) - a $6 million electric rate reduction, which was instituted October 1, 1996, followed by an additional $12 million electric rate reduction effective with the implementation of new gas rates on February 1, 1997, - an annual electric department earnings test with the sharing of earnings in excess of an 11% return on equity for the calendar years 1997-2001 as follows: Electric Department Sharing of Excess Earnings -------------------------- Return on Equity Customers Shareholders ---------------- --------- ------------ 11-12% 65% 35% 12-14% 50% 50% 14-15% 35% 65% over 15% 100% 0%; - the termination of the Qualifying Facilities Capacity Cost Adjustment ("QFCCA") earnings test which was to become effective on October 1, 1996; - a freeze in base electric rates for the period through December 31, 2001 with the flexibility to make certain other rate changes, including those necessary to allow for the recovery of DSM, Qualifying Facility ("QF") and decommissioning costs; - a replacement of the Company's ECA with an ICA to allow for a 50%/50% sharing of certain fuel and energy cost increases or decreases among customers and shareholders; and - the implementation of a Quality of Service Plan ("QSP") which provides for penalties totaling up to $5 million in year one and increasing to $11 million in year five, if the Company does not achieve certain performance measures relating to electric reliability, customer complaints and telephone response to inquiries. A new docket was opened on March 31, 1997 to address the implementation of a reward structure for performance above certain standards. The rate reductions, the earnings sharing, the QSP and the adoption of an ICA will remain in effect even if the Merger is not consummated. The freeze in base electric rates does not prohibit the Company from filing a general rate case or deny any party the opportunity to initiate a complaint or show cause proceeding. Rate Cases On June 5, 1996, the Company filed a retail rate case with the CPUC requesting an annual increase in its jurisdictional gas department revenues of approximately $34 million. In early 1997, the CPUC approved an overall increase of approximately $18 million with an 11.25% return on equity, effective February 1, 1997. The Company intends to appeal the CPUC's decision which disallowed the recovery of certain postemployment benefit costs under SFAS 112 (see Note 1) and imputed anticipated merger related cost savings related to the gas business. The Company filed a rate case with the FERC on December 29, 1995, requesting a slight overall rate increase (less than 1%) from its wholesale electric customers. This filing, among other things, requested approval for recovery of Other Postretirement Employee Benefits ("OPEB") costs under Statement of Financial Accounting Standards No. 106 - "Employers' Accounting for Postretirement Benefits Other Than Pensions", postemployment benefit costs under SFAS 112 and new depreciation rates based on the Company's most recent depreciation study. On March 29, 1996, the FERC issued an order accepting for filing and suspending certain proposed rate changes. Settlement agreements have been reached with all parties and filed with the FERC, which, overall, results in a slight decrease in rates. A final order is expected to be issued in the second quarter of 1997. Electric and Gas Cost Adjustment Mechanisms During 1994 and 1995, the CPUC conducted several proceedings to review issues related to the ECA. The CPUC opened a docket to review whether the ECA should be maintained in its present form, altered or eliminated, and 9 NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued) on January 8, 1996, combined this docket with the merger docket discussed above. The CPUC decision on the Merger modified and replaced the ECA with an ICA. The ICA, which became effective October 1, 1996, allows for a 50%/50% sharing of certain fuel and energy cost increases and decreases among customers and shareholders. The CPUC has had an on-going docket to review and prescribe a standardized GCA process to determine the prudence of gas commodity and pipeline delivery service costs incurred by gas utilities. Other issues addressed in this docket included whether the GCA should be maintained in its present form, altered or eliminated. The CPUC issued an order on April 8, 1997 which provides for the current GCA to be maintained and the adoption of certain standardized filing and gas purchase reporting requirements. Environmental Issues Environmental Site Cleanup As described below, the Company has been or is currently involved with the clean-up of contamination from certain hazardous substances. In all situations, the Company is pursuing or intends to pursue insurance claims and believes it will recover some portion of these costs through such claims. Additionally, where applicable, the Company intends to pursue recovery from other Potentially Responsible Parties ("PRPs"). To the extent such costs are not recovered, the Company currently believes it is probable that such costs will be recovered through the rate regulatory process. To the extent any costs are not recovered through the options listed above, the Company would be required to recognize an expense for such unrecoverable amounts. Under the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), the U.S. Environmental Protection Agency ("EPA") has identified, and a Phase II environmental assessment has revealed, low level, widespread contamination from hazardous substances at the Barter Metals Company ("Barter") properties located in central Denver. For an estimated 30 years, the Company sold scrap metal and electrical equipment to Barter for reprocessing. The Company has completed the cleanup of this site at a cost of approximately $9 million and has received responses from the Colorado Department of Public Health and Environment ("CDPHE") indicating that no further action is required related to these properties. On January 3, 1996, in a lawsuit by the Company against its insurance providers, the Denver District Court entered final judgment in favor of the Company in the amount of $5.6 million for certain cleanup costs at Barter. Several appeals and cross appeals have been filed by one of the insurance providers and the Company in the Colorado Court of Appeals. The insurance provider has posted supersedeas bonds in the amount of $9.7 million ($7.7 million attributable to the Barter judgment). Previously, the Company had received certain insurance settlement proceeds from other insurance providers for Barter and other contaminated sites and a portion of those funds remains to be allocated to this site by the trial court. In addition, the Company expects to recoup additional expenditures beyond insurance proceeds through the sale of the Barter property and from other PRPs. In August 1996, the Company filed a lawsuit against four PRPs seeking recovery of certain Barter related costs. Polychlorinated biphenyl ("PCB") presence was identified in the basement of an historic office building located in downtown Denver. The Company was negotiating the future cleanup with the current owners; however, on October 5, 1993, the owners filed a civil action against the Company in the Denver District Court. The action alleged that the Company was responsible for the PCB releases and additionally claimed other damages in unspecified amounts. On August 8, 1994, the Denver District Court entered a judgment approving a $5.3 million offer of settlement between the Company and the building owners resolving all claims. In December 1995, complaints were filed by the Company against all applicable insurance carriers in the Denver District Court. A trial date regarding the insurance carriers has been established for August 1997. The Ramp Industries disposal facility, located in Denver, Colorado has been designated by the EPA as a Superfund hazardous substance site pursuant to CERCLA. On November 29, 1995, the Company received from the EPA a Notice of Potential Liability and Request for Information related to such site and the Company has responded to this request. The EPA is conducting an investigation of the contamination at this site and is in the process of identifying 10 NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued) the nature and quantities of hazardous wastes delivered to, processed and currently stored at the site by PRPs. In April, 1997, the EPA informed the Company and more than 1,000 other PRPs (as well as the public) that it plans to thermally treat and dispose of RAMP hazardous substances off-site. The EPA estimates the cost of this remedy at between $900,000 and $1.4 million. In addition to these sites, the Company has identified several sites where cleanup of hazardous substances may be required. While potential liability and settlement costs are still under investigation and negotiation, the Company believes that the resolution of these matters will not have a material adverse effect on its financial position, results of operations or cash flows. The Company fully intends to pursue the recovery of all significant costs incurred for such projects through insurance claims and/or the rate regulatory process. Environmental Matters Related to Air Quality and Pollution Control Under the Clean Air Act Amendments of 1990, coal burning power plants are required to reduce sulfur dioxide ("SO2") and nitrogen oxide ("NOx") emissions to specified levels through a phased approach. The Company`s facilities must comply with the Phase II requirements which will be effective in the year 2000. The Company expects to meet the Phase II emission standards placed on SO2 through the use of low sulfur coal and the operation of pollution control equipment on certain generation facilities. The Company will be required to modify certain boilers by the year 2000 to reduce the NOx emissions in order to comply with Phase II requirements. The estimated Phase II costs for future plant modifications to meet NOx requirements is approximately $13 million. The Company is studying its options to reduce NOx and SO2 emissions and, currently does not anticipate that these regulations will significantly impact its operations. Craig Steam Electric Generating Station On October 9, 1996, a conservation organization filed a complaint in the U.S. District Court pursuant to provisions of the Federal Clean Air Act (the "Act") against the joint owners of the Craig Steam Electric Generating Station. Tri-State is the operator of the Craig station and the Company owns an undivided interest (acquired in April 1992) in each of two units at the station totaling approximately 9.7%. The plaintiff alleged that: 1) the station exceeded the 20% opacity limitations in excess of 14,000 six minute intervals during the period extending from the first quarter of 1991 through the second quarter of 1996, and 2) the owners failed to operate the station in a manner consistent with good air pollution control practices. The complaint seeks, among other things, civil monetary penalties and injunctive relief. The Act provides for penalties of up to $25,000 per day per violation, but the level of penalties imposed in any particular instance is discretionary. The Company does not believe that its potential liability or the future impact of this litigation on plant operations will have a material adverse impact on the Company's results of operations, financial position or cash flows. This litigation is similar to the Hayden Station complaint which was settled in 1996 as disclosed in the Company's 1996 Annual Report on Form 10-K. Valmont Steam Electric Generating Station On July 1, 1996, the Company received a Notice of Violation ("NOV") from the CDPHE which alleges inadequate reporting of NOx and SO2 information and excess NOx emissions at the Valmont Steam Electric Generating Station for the period January 1, 1995 through August 22, 1995. In April 1997, the Company settled the NOV with the CDPHE in a manner which did not have a material adverse impact on the Company's results of operations, financial position or cash flows. Employee Litigation Several employee lawsuits have been filed against the Company involving alleged discrimination and breach of certain fiduciary duties to employees. The Company is actively contesting all such lawsuits and believes that the ultimate outcome will not have a material adverse impact on the Company's results of operations, financial position or cash flow. 11 NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued) On August 13, 1996, eighty-eight former Information Technology and Systems ("IT&S") employees filed a lawsuit against the Company. The complaint, which was subsequently amended to add two other former IT&S employees, alleges that the Company unfairly amended its severance plan in connection with a restructuring in late 1994 to exclude the IT&S function/positions that were outsourced to IBM, effective February 1, 1995. The Company believes that the amended severance plan is lawful and enforceable and believes that the ultimate outcome of the lawsuit will not have a material adverse impact on the Company's results of operations, financial position or cash flows. On July 19, 1996, a class action complaint was filed by fourteen plaintiffs, which was subsequently amended to include three additional plaintiffs, allegedly on behalf of all non-managerial, non-clerical women in the Company's regional facilities. The complaint asserts that the Company has engaged in a company-wide pattern and practice of sexual discrimination, including sexual harassment and retaliation. A previous class complaint filed by some of these plaintiffs along with other named plaintiffs, was withdrawn after the Company filed its response. It is too early to predict the outcome of the class action complaint. The Company intends to actively contest the class action and believes the ultimate outcome of the individual plaintiffs' cases will not have a material adverse impact on the Company's results of operations, financial position or cash flows. Certain employees terminated as part of the Company's 1991/1992 organizational analysis asserted breach of contract and promissory estoppel with respect to job security and breach of the covenant of good faith and fair dealing. Of the 21 actions filed, the trial court directed verdicts in favor of the Company in 19 cases. A jury entered verdicts adverse to the Company in two cases which were subsequently appealed by the Company. On February 6, 1997, the Colorado Court of Appeals issued a decision on all issues in favor of the Company and on April 3, 1997 the employees appealed the decision of the Colorado Court of Appeals to the Colorado Supreme Court. The Company believes that the ultimate outcome of the lawsuit will not have a material adverse impact on the Company's results of operations, financial position or cash flow. During 1996, the International Brotherhood of Electrical Workers, Local 111 ("IBEW Local 111") filed several grievances before the National Labor Relations Board relating to the employment of certain non-union personnel to perform services for the Company. A decision has been entered on three of the multiple grievances, with two of those decisions requiring that the Company pay union wage rates on new construction jobs performed by outside vendors. The Company had filed suit seeking to reverse one of these decisions and challenging the subcontracting provision of the labor agreement, all of the outstanding subcontracting grievances and both of the existing adverse decisions as violations of federal law. The Company and the union have reached a settlement resolving all issues and the Company has withdrawn its' previously filed lawsuit. Approximately 45% of the Company's workforce is represented by IBEW Local 111. 5. Acquisition and Divestiture of Investments Acquisition of Yorkshire Electricity On February 24, 1997, the Company and American Electric Power ("AEP") jointly announced that they had reached agreement with the board of directors of Yorkshire Electricity Group plc ("Yorkshire Electricity"), a United Kingdom regional electricity company, on the terms of a recommended cash tender offer for all of the outstanding and to be issued ordinary shares of Yorkshire Electricity. On April 1, 1997, the Company and AEP announced that Yorkshire Holdings plc ("Yorkshire Holdings"), a joint venture among the Company and AEP, had declared the cash tender offer wholly unconditional in all respects and, thereby, committed to purchase all the outstanding shares of Yorkshire Electricity. As of April 30, 1997, valid acceptances of Yorkshire Holdings' offer to purchase shares of Yorkshire Electricity have been received representing approximately 96.25% of Yorkshire Electricity's issued share capital. Under the provisions of the United Kingdom's Companies Act 1985, Yorkshire Holdings intends to exercise its 12 NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued) rights to acquire, under the terms of the offer, the remaining shares in Yorkshire Electricity in respect of which acceptances of the offer have not yet been received. Total consideration to be paid by Yorkshire Holdings is estimated to be approximately $2.4 billion (1.5 billion pounds sterling). Yorkshire Holdings is a wholly-owned subsidiary of Yorkshire Power Group Ltd. ("Yorkshire Power"), which is equally owned by subsidiary companies of the Company and AEP. The acquisition will be financed by Yorkshire Power through a combination of approximately 25% equity and 75% debt, including the assumption of the existing debt of Yorkshire Electricity. The funds for the acquisition will be obtained from the Company's and AEP's investment in Yorkshire Power of approximately $360 million (220 million pounds sterling) each, with the remainder to be obtained by Yorkshire Power through the issuance of non-recourse debt. Yorkshire Power will, in turn, fund Yorkshire Holdings for the purpose of the acquisition. The Company initially funded its entire equity investment in Yorkshire Power through $250 million of publicly issued secured medium-term notes with varying maturities and drawings of $110 million on its short-term lines of credit pursuant to its short-term credit agreement with Bank of America as agent. At March 31, 1997, these funds were invested in temporary cash investments in anticipation of the equity investment to be made in April 1997. The Company will have an indirect 50% ownership interest in Yorkshire Electricity, which will be accounted for using the equity method of accounting. 6. Management's Representations In the opinion of the Company, the accompanying unaudited consolidated condensed financial statements include all adjustments necessary for the fair presentation of the financial position of the Company and its subsidiaries at March 31, 1997 and December 31, 1996, and the results of operations and cash flows for the three months ended March 31, 1997 and 1996. The consolidated condensed financial information and notes thereto should be read in conjunction with the consolidated financial statements and notes for the years ended December 31, 1996, 1995 and 1994 included in the Company's 1996 Annual Report on Form 10-K filed with the Securities and Exchange Commission. Because of seasonal and other factors, the results of operations for the three months ended March 31, 1997 should not be taken as an indication of earnings for all or any part of the balance of the year. 13 REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF PUBLIC SERVICE COMPANY OF COLORADO We have reviewed the accompanying consolidated condensed balance sheet of Public Service Company of Colorado (a Colorado corporation) and subsidiaries as of March 31, 1997, and the related consolidated condensed statements of income and cash flows for the three month periods ended March 31, 1997 and 1996. 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 Public Service Company of Colorado and subsidiaries as of December 31, 1996 (not presented herein), and, in our report dated February 24, 1997, we expressed an unqualified opinion on that statement. In our opinion, the information set forth in the accompanying consolidated condensed balance sheet as of December 31, 1996, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived. ARTHUR ANDERSEN LLP Denver, Colorado, May 12, 1997 14 Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations Earnings Earnings per share were $0.92 for the first quarter of 1997 as compared to $0.97 for the first quarter of 1996. While earnings were positively impacted by continued customer growth contributing to increased electric sales and gas deliveries as well as the Company's cost containment efforts, there was a decline in the 1997 first quarter earnings as compared to the same period in 1996. This decline was attributable to the favorable impact in 1996 of the February 9, 1996 settlement agreement with the DOE resolving all spent nuclear fuel storage and disposal issues at Fort St. Vrain (see Note 2. Fort St. Vrain in Item 1. FINANCIAL STATEMENTS) offset, in part, by the recognition of various non-recurring expense items during that period. Electric Operations The following table details the change in electric operating revenues and energy costs for the first quarter of 1997 as compared to the same period in 1996. Increase (Decrease) ------------------- (Thousands of Dollars) Electric operating revenues: Retail............................................... $(5,799) Wholesale............................................ 1,449 Non-regulated power marketing........................ 5,648 Other (including unbilled revenues).................. 2,538 ------- Total revenues...................................... 3,836 Fuel used in generation............................... (2,076) Purchased power....................................... 191 ------- Net increase in electric margin..................... $ 5,721 ======= The following table compares electric Kwh sales by major customer classes for the first quarter of 1997 and 1996. Millions of Kwh Sales --------------------- 1997 1996 %Change * ---- ---- --------- Residential ............................... 1,867 1,833 1.9% Commercial and Industrial ................ 3,842 3,776 1.8 Public Authority .......................... 48 51 (6.4) ----- ----- Total Retail............................. 5,757 5,660 1.7 Wholesale.................................. 850 792 7.4 Non-regulated power marketing.............. 367 - - ----- ----- Total.................................... 6,974 6,452 8.1 ===== ===== * Percentages are calculated using unrounded amounts Electric margin increased in the first quarter of 1997, when compared to the first quarter of 1996, primarily due to higher electric Kwh retail sales resulting from customer growth offset, in part, by lower fuel costs and rate reductions effective October 1, 1996 and February 1, 1997, which resulted from the settlement of the Merger proceedings in Colorado (see Note 4. Commitments and Contingencies - Merger in Item 1. FINANCIAL STATEMENTS). Power marketing activities by non-regulated subsidiaries initiated in the third quarter of 1996 have contributed to increased operating revenues, however, the margin on such sales is minimal. The Company and Cheyenne have cost adjustment mechanisms which recognize the majority of the effects of changes in fuel used in generation and purchased power costs and allow recovery of such costs on a timely basis. As a result, the changes in revenues associated with these mechanisms during the first quarters of 1997 and 1996 had little impact on net income. However, as discussed in Note 4. Commitments and 15 Contingencies - Regulatory Matters in Item 1. FINANCIAL STATEMENTS, in its decision on the Merger, the CPUC replaced the Company's ECA with an ICA, effective October 1, 1996, which allows for a 50%/50% sharing of certain fuel and energy cost increases and decreases among customers and shareholders. The change did not impact the cost recoveries for the first quarter of 1997. Fuel used in generation expense decreased approximately 4.5% during the first quarter of 1997, as compared to the same quarter in 1996, due to decreased generation levels at the Company's power plants and lower coal supply costs in the first quarter of 1997. Purchased power expense increased slightly during the first quarter of 1997, as compared to the same quarter in 1996. Costs incurred in connection with the increased non-regulated power marketing sales were partially offset by the lower costs of economy purchases from other utilities to meet customer demand. Gas Operations The following table details the change in revenues from gas sales and gas purchased for resale for the first quarter of 1997 as compared to the same period in 1996. Increase (Decrease) ------------------- (Thousands of Dollars) Revenues from gas sales (including unbilled revenues). 48,470 Gas purchased for resale.............................. 46,628 ------- Net increase in gas sales margin..................... $ 1,842 ======= The following table compares gas decatherm (Dth) deliveries by major customer classes for the first quarter of 1997 and 1996. Millions of Dth Deliveries -------------------------- 1997 1996 % Change * ---- ---- ---------- Residential................................ 39.6 39.0 1.4% Commercial................................. 21.3 22.3 (4.4) Non-regulated gas marketing................ 15.6 0.7 ** ----- ----- Total Sales.............................. 76.5 62.0 23.4 Gathering and Processing................... 0.1 0.2 ** Transportation............................. 25.1 22.3 12.6 ----- ----- Total.................................... 101.7 84.5 20.3 ===== ===== * Percentages are calculated using unrounded amounts ** Percentage change is significant, but presentation of the amount is not meaningful Gas sales margin increased in the first quarter of 1997, when compared to the first quarter of 1996, primarily due to an increase in the Company's base revenues associated with the higher rates effective February 1, 1997, resulting from the Company's 1996 rate case and higher retail gas sales resulting from annual customer growth of approximately 3.5%. In addition, gas marketing activities by non-regulated subsidiaries favorably contributed to the increase in gas sales margin. Gas costs were higher during the first quarter of 1997, as compared to the same period of 1996, as a result of higher gas prices incurred through the winter heating season. Gas transportation, gathering, processing and other revenues increased $1.1 million during the first quarter of 1997, when compared to the first quarter of 1996, primarily due to an increase in transport deliveries. The higher transport deliveries are attributable to the shifting of various Company commercial sales customers to firm transport customers. Historically, this shifting has not had an impact on gas margin and is not expected to have an impact in the future. 16 The Company and Cheyenne have in place GCA mechanisms for natural gas sales, which recognize the majority of the effects of changes in the cost of gas purchased for resale and adjust revenues to reflect such changes in cost on a timely basis. As a result, the changes in revenues associated with these mechanisms during the first quarters of 1997 and 1996 had little impact on net income. However, the fluctuations in gas sales impact the amount of gas the Company must purchase and, therefore, along with the increases and decreases in the per-unit cost of gas, affect total gas purchased for resale. Non-Fuel Operating Expenses Other operating and maintenance expenses increased $9.7 million during the first quarter of 1997, as compared to the same period in 1996, primarily due to the favorable impact on 1996 first quarter earnings of the February 9, 1996 settlement agreement with the DOE resolving all spent nuclear fuel storage and disposal issues at Fort St. Vrain (approximately $16 million) offset, in part, by costs incurred during the first quarter of 1996 associated with the settlement agreement of certain environmental issues related to the operations of the Hayden Steam Electric Generation Station. In addition, the current period results were favorably impacted by lower employee benefit costs and other general reductions resulting from the Company's cost containment efforts. Depreciation and amortization expense increased $6.0 million, or 16.3%, in the first quarter of 1997, as compared to the same period in 1996, primarily due to the depreciation of property additions and the higher amortization of software costs. The decrease in income taxes for the first quarter of 1997, as compared to the same period in 1996, is primarily due to lower pre-tax income, the tax effects of recognizing certain non-deductible environmental and Merger costs in 1996 and the prior year accrual for additional tax liabilities. Miscellaneous income and deductions - net increased $4.4 million primarily due to lower Merger costs in 1997 and higher interest income on temporary cash investments, which resulted from the borrowings in anticipation of the investment to be made in acquiring Yorkshire Electricity. See Note 5. Acquisition and Divestiture of Investments Acquisition of Yorkshire Electricity in Item 1. FINANCIAL STATEMENTS. Interest expense increased $5.4 million during the first quarter of 1997, when compared to the same quarter in 1996, primarily due to interest on borrowings utilized to finance capital expenditures and the anticipated acquisition of Yorkshire Electricity. These borrowings included the issuance of $75 million and $250 million of medium-term notes in January and March 1997, respectively. Financial Position Accounts payable decreased approximately $100 million at March 31, 1997, as compared to December 31, 1996, primarily due to the impact of seasonally lower gas purchases. This also contributed to the reduction in accounts receivable. Commitments and Contingencies Issues relating to regulatory and environmental matters are discussed in Note 4 in Item 1. FINANCIAL STATEMENTS. These matters and the future resolution thereof may impact the Company's future results of operations, financial position or cash flows. Common Stock Dividend In March 1997, the Board of Directors ("the Board") approved a common stock dividend at the rate of $0.525 per share. In anticipation of the effective date of the Merger, in April 1997 the Board approved a partial dividend payable to shareholders of the Company covering the period April 12, 1997 through the day prior to the Merger completion, based on the quarterly dividend rate of $0.525, but prorated for the number of days in the interim 17 period. This dividend is approved as long as the effective date of the Merger is not later than July 1, 1997. During the first quarter of 1996, the Company increased the quarterly common stock dividend of $0.51 per share to $0.525 per share. The Company's common stock dividend level is dependent upon the Company's results of operations, financial position, cash flows and other factors. The Board of Directors of the Company will continue to evaluate the common stock dividend level on a quarterly basis. After consummation of the Merger, dividends will be paid to NCE as the holder of all of the Company's common stock. Liquidity and Capital Resources Cash Flows - Three Months Ended March 31 1997 1996 Decrease ---- ---- -------- Net cash provided by operating activities (in millions) $68.2 $123.3 $(55.1) Cash provided by operating activities decreased in the first three months of 1997, when compared to the first three months of 1996, primarily due to the increase in payments to gas suppliers resulting from the higher gas costs in late 1996 and early 1997. A portion of these higher gas costs have been deferred through the GCA and will be recovered from customers in the future. These decreases were offset, in part, by an increase in accounts receivable which was attributable to a gas refund made late in 1995 that was applied directly to customers' accounts and served to lower cash receipts during the first quarter of 1996. 1997 1996 Decrease ---- ---- -------- Net cash used in investing activities (in millions) $(52.5) $(60.7) $(8.2) Cash used in investing activities decreased during the three months ended March 31, 1997, when compared to the same period in 1996, primarily due to lower construction expenditures. 1997 1996 Increase ---- ---- -------- Net cash provided by (used in) financing activities (in millions) $343.3 $(64.8) $408.1 Cash provided by financing activities increased (indicating that there were more borrowings) in the first three months of 1997, when compared to the first three months of 1996, primarily due to the issuance of $75 million and $250 million of medium term notes in January and March 1997, respectively. The proceeds from the $75 million financing were used to fund the Company's construction program. The Company used the proceeds from the $250 million medium term notes, together with additional borrowings of approximately $110 million on its short-term lines of credit, to fund its acquisition of Yorkshire Electricity.

ARTICLE ONE CREATION AND DESCRIPTION OF THE COLLATERAL SERIES E BONDS SECTION 1. A new series of bonds to be issued from time to time under and secured by the Indenture is hereby created, the bonds of such new series to be designated First Mortgage Bonds, Collateral Series E. The Collateral Series E Bonds shall be limited to an aggregate principal amount of One Hundred Fifty Million dollars ($150,000,000), excluding any Collateral Series E Bonds which may be authenticated and exchanged for or in lieu of or in substitution for or on transfer of other Collateral Series E Bonds pursuant to any provisions of the Indenture. The Collateral Series E Bonds shall not bear interest and each Collateral Series E Bond shall (a) be issued in such principal amount, (b) mature on such date not less than nine months nor more than thirty years from its Original Issue Date (as hereinafter defined), and (c) have such other terms and conditions as shall not be inconsistent with the provisions of the Indenture, all as shall be specified by the Company in a certificate, executed by the President, any Vice President, the Treasurer or any Assistant Treasurer of the Company, delivered to the Trustee relating to such Collateral 3 Series E Bond and referring to this Supplemental Indenture (each such certificate being deemed to constitute a part of this Supplemental Indenture and being hereinafter sometimes called an "Issuance Certificate"), such specification by such an officer of the Company in an Issuance Certificate having been heretofore authorized in a resolution of the Board of Directors of the Company. The principal of each Collateral Series E Bond shall be payable, upon presentation thereof, at the office or agency of the Company in the city in which the principal corporate trust office of the 1993 Mortgage Trustee (as hereinafter defined) is located, in any coin or currency of the United States of America which at the time of payment shall be legal tender for the payment of public and private debts. The Collateral Series E Bonds shall be issued and delivered from time to time by the Company to First Trust of New York, National Association, as successor trustee under the Indenture, dated as of October 1, 1993, as supplemented (the "1993 Mortgage"), of the Company to such trustee (the "1993 Mortgage Trustee"), as the basis for the authentication and delivery under the 1993 Mortgage of a series of securities. As provided in the 1993 Mortgage, the Collateral Series E Bonds will be registered in the name of the 1993 Mortgage Trustee or its nominee and will be owned and held by the 1993 Mortgage Trustee, subject to the provisions of the 1993 Mortgage, for the benefit of the holders of all securities from time to time outstanding under the 1993 Mortgage, and the Company shall have no interest therein. Any payment by the Company under the 1993 Mortgage of the principal of any securities which shall have been authenticated and delivered under the 1993 Mortgage on the basis of the issuance and delivery to the 1993 Mortgage Trustee of Collateral Series E Bonds (other than by the application of the proceeds of a payment in respect of such Collateral Series E Bonds) shall, to the extent thereof, be deemed to satisfy and discharge the obligation of the Company, if any, to make a payment of principal of such Collateral Series E Bonds which is then due. The Trustee may conclusively presume that the obligation of the Company to pay the principal of any Collateral Series E Bonds as the same shall become due and payable shall have been fully satisfied and discharged unless and until it shall have received a written notice from the 1993 Mortgage Trustee, signed by an authorized officer thereof, stating that the principal of specified Collateral Series E Bonds has become due and payable and has not been fully paid, and specifying the amount of funds required to make such payment. Each Collateral Series E Bond shall be dated as of the date of its authentication.

The Collateral Series E Bonds shall be registerable and exchangeable at the office or agency of the Company in the city in which the principal corporate trust office of the 1993 Mortgage Trustee is located, in the manner and upon the terms set forth in Section 5 of Article II of the Indenture; provided, however, that the Collateral Series E Bonds shall not be transferrable except to a successor trustee under the 1993 Mortgage. No service charge shall be made for any exchange or transfer of any Collateral Series E Bond. If and to the extent necessary to eliminate any apparent inconsistency between any provision of this Supplemental Indenture and any provision of the Indenture all Collateral Series E Bonds having the same Original Issue Date, Stated Maturity, interest rate, and other terms and conditions shall be deemed to be a separate series of bonds, and such Original Issue Date, Stated Maturity, interest rate, if any, and other terms and conditions shall be deemed to be a part of the designation of such series. 4 As used herein, the term "Original Issue Date" shall mean, with respect to any Collateral Series E Bond, the date of authentication and delivery hereunder of such Collateral Series E Bond, or, in the case of any particular Collateral Series E Bond which has been authenticated and delivered upon the registration of transfer or exchange of, or in substitution for, another Collateral Series E Bond, the date of the original authentication and delivery hereunder of the first Collateral Series E Bond authenticated and delivered hereunder representing all or a portion of the same obligation as that evidenced by such particular Collateral Series E Bond; the term "Stated Maturity" shall mean, with respect to any Collateral Series E Bond, the date on which the principal of such Collateral Series E Bond is stated to be due and payable (without regard to any provision for acceleration, redemption or similar provisions); and the term "Maturity" shall mean, with respect to any Collateral Series E Bond, the date on which the principal of such Collateral Series E Bond becomes due and payable, whether at Stated Maturity, by declaration of acceleration, upon call for redemption or otherwise. SECTION 2. The text of the Collateral Series E Bonds shall be substantially in the form attached hereto as Exhibit A. SECTION 3. The Collateral Series E Bonds may be executed by the Company and delivered to the Trustee and, upon compliance with all applicable provisions and requirements of the Indenture in respect thereof, shall be authenticated by the Trustee and delivered (without awaiting the filing or recording of this Supplemental Indenture), from time to time, in accordance with the written order or orders of the Company. ARTICLE TWO REDEMPTION OF THE COLLATERAL SERIES E BONDS SECTION 1. No Collateral Series E Bond shall be subject to any sinking fund or other mandatory redemption (whether at the option of the holder thereof or otherwise) unless otherwise specified in the Issuance Certificate relating to such Collateral Series E Bond. Each Collateral Series E Bond shall be redeemable at the option of the Company in whole at any time, or in part from time to time, prior to Stated Maturity, at a redemption price equal to 100% of the principal amount thereof to be redeemed. SECTION 2. The provisions of Sections 3, 4, 5, 6 and 7 of Article V of the Indenture shall be applicable to the Collateral Series E Bonds, except that (a) no publication of notice of redemption of the Collateral Series E Bonds shall be required and (b) if less than all the Collateral Series E Bonds are to be redeemed, the Collateral Series E Bonds to be redeemed shall be selected from the maturities, and in the principal amounts, designated to the Trustee by the Company, and except as such provisions may otherwise be inconsistent with the provisions of this Article Two. SECTION 3. The holder of each and every Collateral Series E Bond issued hereunder hereby agrees to accept payment thereof prior to Stated Maturity on the terms and conditions provided for in this Article Two. ARTICLE THREE. ACKNOWLEDGMENT OF RIGHT TO VOTE OR CONSENT WITH RESPECT TO CERTAIN AMENDMENTS TO INDENTURE 5 The Company hereby acknowledges the right of the holders of the Collateral Series E Bonds to vote or consent with respect to any or all of the modifications to the Indenture referred to in Article Three of the Supplemental Indenture, dated as of March 1, 1980, irrespective of the fact that the Bonds of the Second 1987 Series are no longer outstanding; provided, however, that such acknowledgment shall not impair (a) the right of the Company to make such modifications without the consent or other action of the holders of the Bonds of the 2020 Series or the bonds of any other series subsequently created under the Indenture with respect to which the Company has expressly reserved such right or (b) the right of the Company to reserve the right to make such modifications without the consent or other action of the holders of bonds of one or more, or any or all, series created subsequent to the creation of the Collateral Series E Bonds.

ARTICLE FIVE MISCELLANEOUS PROVISIONS SECTION 1.

All covenants and provisions of the Indenture shall continue in full force and effect and this Supplemental Indenture shall form part of the Indenture. SECTION 2.
