MDU RESOURCES GROUP, INC. Report of Management The management of MDU Resources Group, Inc. is responsible for the preparation, integrity and objectivity of the financial information contained in the consolidated financial statements and elsewhere in this Annual Report. The financial statements have been prepared in conformity with generally accepted accounting principles as applied to the company's regulated and nonregulated businesses and necessarily include some amounts that are based on informed judgments and estimates of management. To meet its responsibilities with respect to financial information, management maintains and enforces a system of internal accounting controls designed to provide assurance, on a cost-effective basis, that transactions are carried out in accordance with management's authorizations and that assets are safeguarded against loss from unauthorized use or disposition. The system includes an organizational structure which provides an appropriate segregation of responsibilities, effective selection and training of personnel, written policies and procedures and periodic reviews by the Internal Auditing Department. In addition, the company has a policy which requires all employees to acknowledge their responsibility for ethical conduct. Management believes that these measures provide for a system that is effective and reasonably assures that all transactions are properly recorded for the preparation of financial statements. Management modifies and improves its system of internal accounting controls in response to changes in business conditions. The company's Internal Auditing Department is charged with the responsibility for determining compliance with company procedures. The Board of Directors, through its audit committee which is comprised entirely of outside directors, oversees management's responsibilities for financial reporting. The audit committee meets regularly with management, the internal auditors and Arthur Andersen LLP, independent public accountants, to discuss auditing and financial matters and to assure that each is carrying out its responsibilities. The internal auditors and Arthur Andersen LLP have full and free access to the audit committee, without management present, to discuss auditing, internal accounting control and financial reporting matters. Arthur Andersen LLP is engaged to express an opinion on the financial statements. Their audit is conducted in accordance with auditing standards generally accepted in the United States and includes examining, on a test basis, supporting evidence, assessing the company's accounting principles used and significant estimates made by management and evaluating the overall financial statement presentation to the extent necessary to allow them to report on the fairness, in all material respects, of the financial condition and operating results of the company. Martin A. White Warren L. Robinson Chairman of the Board, Executive Vice President, President and Chief Treasurer and Chief Executive Officer Financial Officer Report of Independent Public Accountants To MDU Resources Group, Inc. We have audited the accompanying consolidated balance sheets of MDU Resources Group, Inc. (a Delaware corporation) and Subsidiaries as of December 31, 2000 and 1999, and the related consolidated statements of income, common stockholders' equity and cash flows for each of the three years in the period ended December 31, 2000. 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 auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of MDU Resources Group, Inc. and Subsidiaries as of December 31, 2000 and 1999, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2000, in conformity with accounting principles generally accepted in the United States.

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The consolidated financial statements of MDU Resources Group, Inc. and its subsidiaries (company) include the accounts of the following segments: electric, natural gas distribution, utility services, pipeline and energy services, natural gas and oil production, and construction materials and mining. The electric and natural gas distribution segments and a portion of the pipeline and energy services segment are regulated. The company's nonregulated operations include the utility services, natural gas and oil production, and construction materials and mining segments, and a portion of the pipeline and energy services segment. For further descriptions of the company's business segments see Note 9. The statements also include the ownership interests in the assets, liabilities and expenses of two jointly owned electric generation stations. The company's regulated businesses are subject to various state and federal agency regulation. The accounting policies followed by these businesses are generally subject to the Uniform System of Accounts of the Federal Energy Regulatory Commission (FERC). These accounting policies differ in some respects from those used by the company's nonregulated businesses. The company's regulated businesses account for certain income and expense items under the provisions of Statement of Financial Accounting Standards No. 71, "Accounting for the Effects of Regulation" (SFAS No. 71). SFAS No. 71 requires these businesses to defer as regulatory assets or liabilities certain items that would have otherwise been reflected as expense or income, respectively, based on the expected regulatory treatment in future rates. The expected recovery or flowback of these deferred items are generally based on specific ratemaking decisions or precedent for each item. Regulatory assets and liabilities are being amortized consistently with the regulatory treatment established by the FERC and the applicable state public service commissions. See Note 2 for more information regarding the nature and amounts of these regulatory deferrals. In accordance with the provisions of SFAS No. 71, intercompany coal sales, which are made at prices approximately the same as those charged to others, and the related utility fuel purchases are not eliminated. All other significant intercompany balances and transactions have been eliminated in consolidation. Property, plant and equipment Additions to property, plant and equipment are recorded at cost when first placed in service. When regulated assets are retired, or otherwise disposed of in the ordinary course of business, the original cost and cost of removal, less salvage, is charged to accumulated depreciation. With respect to the retirement or disposal of all other assets, except for natural gas and oil production properties as described below, the resulting gains or losses are recognized as a component of income. The company is permitted to capitalize an allowance for funds used during construction (AFUDC) on regulated construction projects and to include such amounts in rate base when the related facilities are placed in service. In addition, the company capitalizes interest, when applicable, on certain construction projects associated with its other operations. The amount of AFUDC and interest capitalized was $5.2 million, $1.7 million and $1.4 million in 2000, 1999 and 1998, respectively. Property, plant and equipment are depreciated on a straight-line basis over the average useful lives of the assets, except for natural gas and oil production properties as described below. Goodwill and other intangible assets The excess of the cost over the fair value of net assets of purchased businesses is recorded as goodwill and is amortized on a straight-line basis over estimated useful lives. Goodwill was $91.4 million, net of accumulated amortization of $12.0 million as of December 31, 2000 and was $46.7 million, net of accumulated amortization of $5.1 million as of December 31, 1999. Goodwill amortization expense was $7.0 million, $2.0 million and $1.4 million for 2000, 1999 and 1998, respectively. The weighted average amortization period for goodwill as of December 31, 2000 was 25 years. Impairment of long-lived assets and intangibles The company reviews the carrying values of its long-lived assets, including goodwill and identifiable intangibles, whenever events or changes in circumstances indicate that such carrying values may not be recoverable. The determination of whether an impairment has occurred is based on an estimate of undiscounted future cash flows attributable to the assets, compared to the carrying value of the assets. If an impairment has occurred, the amount of the impairment recognized is determined by estimating the fair value of the assets and recording a loss if the carrying value is greater than the fair value. In 2000, the company experienced significant changes in market conditions at one of its energy marketing operations, which negatively affected the fair value of the assets at that operation. Due to the significance of the decline, the company recorded an impairment charge against goodwill of $3.9 million after tax in the fourth quarter of 2000. The amount related to this impairment is included in "Depreciation, depletion and amortization" in the company's Consolidated Statements of Income. Excluding this impairment and the write-downs of natural gas and oil properties as discussed herein, no other long-lived assets or intangibles have been impaired and accordingly no other impairment losses have been recorded in 2000, 1999 and 1998. Unforeseen events and changes in circumstances could require the recognition of other impairment losses at some future date. Natural gas and oil The company uses the full-cost method of accounting for its natural gas and oil production activities. Under this method, all costs incurred in the acquisition, exploration and development of natural gas and oil properties are capitalized and amortized on the units of production method based on total proved reserves. Any conveyances of properties, including gains or losses on abandonments of properties, are treated as adjustments to the cost of the properties with no gain or loss recognized. Capitalized costs are subject to a "ceiling test" that limits such costs to the aggregate of the present value of future net revenues of proved reserves and the lower of cost or fair value of unproved properties. Future net revenue is estimated based on end-of- quarter prices adjusted for contracted price changes. If capitalized costs exceed the full-cost ceiling at the end of any quarter, a permanent noncash write-down is required to be charged to earnings in that quarter. Due to low natural gas and oil prices, the company's capitalized costs under the full-cost method of accounting exceeded the full-cost ceiling at June 30, 1998 and December 31, 1998. Accordingly, the company was required to write down its natural gas and oil producing properties. These noncash write-downs amounted to $66.0 million ($39.9 million after tax). Natural gas in underground storage Natural gas in underground storage for the company's regulated operations is carried at cost using the last-in, first-out method. The portion of the cost of natural gas in underground storage expected to be used within one year is included in inventories and amounted to $11.0 million and $26.1 million at December 31, 2000 and 1999, respectively. The remainder of natural gas in underground storage is included in property, plant and equipment and was $43.6 million and $46.8 million at December 31, 2000 and 1999, respectively. Inventories Inventories, other than natural gas in underground storage for the company's regulated operations, consist primarily of materials and supplies of $20.4 million and $15.9 million, aggregates held for resale of $22.7 million and $15.6 million and other inventories of $9.9 million and $7.0 million as of December 31, 2000 and 1999, respectively. These inventories are stated at the lower of average cost or market. Revenue recognition The company recognizes utility revenue each month based on the services provided to all utility customers during the month. For its construction businesses, the company recognizes construction contract revenue on the percentage of completion method. The company recognizes revenue from natural gas and oil production activities only on that portion of production sold and allocable to the company's ownership interest in the related well. The company generally recognizes all other revenues when services are rendered or goods are delivered. Advertising The company expenses advertising costs as incurred and the amount of advertising expense for the years 2000, 1999 and 1998, was $2.0 million, $1.3 million and $1.0 million, respectively. Natural gas costs recoverable through rate adjustments Under the terms of certain orders of the applicable state public service commissions, the company is deferring natural gas commodity, transportation and storage costs which are greater or less than amounts presently being recovered through its existing rate schedules. Such orders generally provide that these amounts are recoverable or refundable through rate adjustments within a period ranging from 24 months to 28 months from the time such costs are paid. Income taxes The company provides deferred federal and state income taxes on all temporary differences. Excess deferred income tax balances associated with the company's rate-regulated activities resulting from the company's adoption of SFAS No. 109, "Accounting for Income Taxes," have been recorded as a regulatory liability and are included in "Other liabilities" in the company's Consolidated Balance Sheets. These regulatory liabilities are expected to be reflected as a reduction in future rates charged customers in accordance with applicable regulatory procedures. The company uses the deferral method of accounting for investment tax credits and amortizes the credits on electric and natural gas distribution plant over various periods which conform to the ratemaking treatment prescribed by the applicable state public service commissions. Earnings per common share Basic earnings per common share were computed by dividing earnings on common stock by the weighted average number of shares of common stock outstanding during the year. Diluted earnings per common share were computed by dividing earnings on common stock by the total of the weighted average number of shares of common stock outstanding during the year, plus the effect of outstanding stock options and restricted stock grants. Common stock outstanding includes issued shares less shares held in treasury. Comprehensive income For the years ended December 31, 2000, 1999 and 1998, comprehensive income equaled net income as reported. Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the company 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. Estimates are used for such items as property depreciable lives, tax provisions, uncollectible accounts, environmental and other loss contingencies, accumulated provision for revenues subject to refund, costs on long-term construction contracts, unbilled revenues and actuarially determined benefit costs. As better information becomes available, or actual amounts are determinable, the recorded estimates are revised. Consequently, operating results can be affected by revisions to prior accounting estimates. Cash flow information Cash expenditures for interest and income taxes were as follows: Years ended December 31, 2000 1999 1998 (In thousands) Interest, net of amount capitalized $41,912 $30,772 $26,394 Income taxes $30,930 $32,723 $34,498 The company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. New accounting pronouncements In June 1998, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities" (SFAS No. 133), amended by Statement of Financial Accounting Standards No. 137, "Accounting for Derivative Instruments and Hedging Activities - Deferral of the Effective Date of FASB Statement No. 133" and Statement of Financial Accounting Standards No. 138, "Accounting for Certain Derivative Instruments and Certain Hedging Activities" (all such statements hereinafter referred to as SFAS No. 133). SFAS No. 133 establishes accounting and reporting standards requiring that every derivative instrument (including certain derivative instruments embedded in other contracts) be recorded in the balance sheet as either an asset or liability measured at its fair value. SFAS No. 133 requires that changes in the derivative's fair value be recognized currently in earnings unless specific hedge accounting criteria are met. Special accounting for qualifying hedges allows derivative gains and losses to offset the related results on the hedged item in the income statement, and requires that a company must formally document, designate and assess the effectiveness of transactions that receive hedge accounting treatment. The company plans to utilize certain derivative financial instruments to manage a portion of the market risk associated with fluctuations in the price of natural gas and oil. The company intends to designate these contracts as hedges of the underlying purchases or sales and will record derivative assets and liabilities on its balance sheet based on the fair value of the contracts. Such amounts are expected to be substantially offset by an amount that will be recorded in "Accumulated other comprehensive income" on the company's Consolidated Balance Sheets. The fair values of derivative instruments will fluctuate over time due to changes in the underlying commodity prices. The company adopted SFAS No. 133 on January 1, 2001. SFAS No. 133 will likely impact the company's financial position and could increase volatility in earnings and accumulated other comprehensive income. Based on the contracts outstanding as of January 1, 2001, pretax unrealized gains on derivatives of $2.2 million and pretax unrealized losses on derivatives of $12.3 million would be recognized as assets and liabilities, respectively, on the balance sheet with the offsetting amounts being recorded as a component of accumulated other comprehensive income. In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 101, "Revenue Recognition" (SAB No. 101), which provides guidance on the recognition, presentation and disclosure of revenue in financial statements. The company adopted SAB No. 101 in the fourth quarter of 2000. The adoption of SAB No. 101 did not have a material effect on the company's financial position or results of operations. NOTE 2 REGULATORY ASSETS AND LIABILITIES The following table summarizes the individual components of unamortized regulatory assets and liabilities included in the accompanying Consolidated Balance Sheets as of December 31: 2000 1999 (In thousands) Regulatory assets: Long-term debt refinancing costs $ 8,125 $ 9,514 Plant costs 2,668 2,835 Natural gas contract settlement and restructuring costs 1,562 3,000 Postretirement benefit costs 833 1,742 Deferred income taxes 263 7,274 Other 5,490 6,789 Total regulatory assets 18,941 31,154 Regulatory liabilities: Taxes refundable to customers 11,656 11,504 Natural gas costs refundable through rate adjustments 8,772 2,579 Plant decommissioning costs 7,601 6,989 Reserves for regulatory matters 6,087 24,231 Deferred income taxes 3,554 6,785 Other 1,193 710 Total regulatory liabilities 38,863 52,798 Net regulatory position $(19,922) $(21,644) As of December 31, 2000, substantially all of the company's regulatory assets, other than certain deferred income taxes, are being reflected in rates charged to customers and are being recovered over the next 1 to 16 years. If, for any reason, the company's regulated businesses cease to meet the criteria for application of SFAS No. 71 for all or part of their operations, the regulatory assets and liabilities relating to those portions ceasing to meet such criteria would be removed from the balance sheet and included in the statement of income as an extraordinary item in the period in which the discontinuance of SFAS No. 71 occurs. NOTE 3 RISK MANAGEMENT ACTIVITIES AND FINANCIAL INSTRUMENTS Derivatives The company utilizes derivative financial instruments, including price swap and collar agreements, to manage a portion of the market risk associated with fluctuations in the price of natural gas and oil. The company's policy prohibits the use of derivative instruments for speculating to take advantage of market trends and conditions and the company has procedures in place to monitor compliance with its policies. The company is exposed to credit-related losses in relation to financial instruments in the event of nonperformance by counterparties, but does not expect any counterparties to fail to meet their obligations given their existing credit ratings. The swap and collar agreements call for the company to receive monthly payments from or make payments to counterparties based upon the difference between a fixed and a variable price as specified by the agreements. The variable price is either a quoted natural gas price on the New York Mercantile Exchange (NYMEX), Colorado Interstate Gas Index or other various indexes or an oil price quoted on the NYMEX. The company believes that there is a high degree of correlation because the timing of purchases and production and the swap and collar agreements are closely matched, and hedge prices are established in the areas of operations. For the years ending December 31, 2000, 1999 and 1998, gains or losses on the swap and collar agreements were matched and reported in operating revenues on the Consolidated Statements of Income as a component of the related commodity transaction at the time of settlement with the counterparty. The following table summarizes hedge agreements entered into by certain wholly owned subsidiaries of the company, as of December 31, 2000. These agreements call for the subsidiaries to receive fixed prices and pay variable prices. (Notional amount and fair value in thousands) Weighted Average Notional Fixed Price Amount Fair (Per MMBtu) (In MMBtu's) Value Natural gas swap agreements maturing $ 4.45 5,461 $(12,311) in 2001 Weighted Average Notional Fixed Price Amount Fair (Per barrel) (In barrels) Value Oil swap agreements maturing in 2001 $28.80 593 $ 2,261 The fair value of these derivative financial instruments reflects the estimated amounts that the company would receive or pay to terminate the contracts at the reporting date, thereby taking into account the current favorable or unfavorable position on open contracts. The favorable or unfavorable position is not recorded on the company's Consolidated Balance Sheets as of December 31, 2000 and 1999. Favorable and unfavorable positions related to commodity hedge agreements are expected to be generally offset by corresponding increases and decreases in the value of the underlying commodity transactions. In the event a derivative financial instrument does not qualify for hedge accounting or when the underlying commodity transaction matures, is sold, is extinguished, or is terminated, the current favorable or unfavorable position on the open contract would be included in results of operations. The company's policy requires approval to terminate a hedge agreement prior to its original maturity. In the event a hedge agreement is terminated, the realized gain or loss at the time of termination would be deferred until the underlying commodity transaction is sold or matures and is expected to generally offset the corresponding increases or decreases in the value of the underlying commodity transaction. Energy marketing The company has energy marketing operations that are exposed to risks, including risks relating to changes in natural gas prices and counterparty performance (credit risk), associated with natural gas forward purchase and sale commitments. These commitments involve the purchase and sale of natural gas and related delivery of such commodity. The energy marketing operations seek to match natural gas purchases and sales on specific contracts so that a margin is obtained on the transportation of such commodity as distinguished from earning a margin on changes in market prices. In addition, the energy marketing contracts are generally entered into on a seasonal basis with contracts of a duration generally not exceeding 12 months. Contracts related to these activities are valued at fair value and changes in fair value are recorded as assets or liabilities on the company's Consolidated Balance Sheets. The net change in fair value representing unrealized gains and losses resulting from changes in market prices on these contracts is reflected in earnings on the company's Consolidated Statements of Income. Net unrealized gains and losses on these contracts were not material in 2000, 1999 or 1998. In general, market risk is the risk of fluctuations in the market price of the commodity being marketed and is influenced primarily by supply and demand. The company monitors and manages its exposure to market risk through a variety of risk management techniques. Such procedures include monitoring commitments and positions, evaluating sensitivity to changes in market prices and market volatility, and reporting to senior management. Credit risk is the risk of loss from nonperformance by counterparties of their contractual obligations. The company maintains credit procedures, which management believes significantly minimize overall credit risk. The company seeks to mitigate credit risk by applying specific eligibility criteria to prospective counterparties and may require letters of credit or similar security to secure payment on such sales contracts. However, despite mitigation efforts, defaults by counterparties may occur. To date, no such defaults have had a material effect on the company's financial position or results of operations. Fair value of other financial instruments The estimated fair value of the company's long-term debt and preferred stock subject to mandatory redemption is based on quoted market prices of the same or similar issues. The estimated fair value of the company's long-term debt and preferred stock subject to mandatory redemption at December 31 is as follows: 2000 1999 Carrying Fair Carrying Fair Amount Value Amount Value (In thousands) Long-term debt $747,761 $772,127 $567,873 $555,730 Preferred stock subject to mandatory redemption $ 1,500 $ 927 $ 1,600 $ 1,418 The fair value of other financial instruments for which estimated fair value has not been presented is not materially different than the related carrying amount. NOTE 4 SHORT-TERM BORROWINGS The company and its subsidiaries had unsecured short-term lines of credit from a number of banks totaling $75 million at December 31, 2000. These line of credit agreements provide for bank borrowings against the lines and/or support for commercial paper issues. The agreements provide for commitment fees at varying rates. Amounts outstanding on the short-term lines of credit were $8 million at December 31, 2000, and $14.7 million at December 31, 1999. The weighted average interest rate for borrowings outstanding at December 31, 2000 and 1999, was 6.60 percent and 6.97 percent, respectively. The unused portions of the lines of credit are subject to withdrawal based on the occurrence of certain events. NOTE 5 LONG-TERM DEBT AND INDENTURE PROVISIONS Long-term debt outstanding at December 31 is as follows: 2000 1999 (In thousands) First mortgage bonds and notes: Pollution Control Refunding Revenue Bonds, Series 1992, 6.65%, due June 1, 2022 $ 20,850 $ 20,850 Secured Medium-Term Notes, Series A at a weighted average rate of 7.59%, due on dates ranging from October 1, 2004 to April 1, 2012 110,000 110,000 Total first mortgage bonds and notes 130,850 130,850 Senior notes at a weighted average rate of 7.65%, due on dates ranging from January 2, 2001 to October 30, 2018 294,300 151,400 Commercial paper at a weighted average rate of 6.93%, supported by a revolving credit agreement due on September 29, 2003 261,350 223,169 Revolving lines of credit at a weighted average rate of 9.36%, due on dates ranging from November 1, 2001 through December 31, 2002 46,302 45,900 Term credit agreements at a weighted average rate of 7.65%, due on dates ranging from March 15, 2001 through July 1, 2016 12,731 13,970 Pollution control note obligation, 6.20%, due March 1, 2004 2,800 3,100 Other (572) (516) Total long-term debt 747,761 567,873 Less current maturities 19,595 4,328 Net long-term debt $ 728,166 $563,545 Centennial Energy Holdings, Inc., (Centennial) a direct wholly owned subsidiary of the company, has a revolving credit agreement with various banks on behalf of its subsidiaries that supports $315 million of Centennial's $325 million commercial paper program. Under the Centennial commercial paper program, $261.4 million and $223.2 million were outstanding at December 31, 2000 and 1999, respectively. The commercial paper borrowings are classified as long term as Centennial intends to refinance these borrowings on a long-term basis through continued commercial paper borrowings supported by the revolving credit agreement due September 29, 2003. Centennial intends to renew this existing credit agreement on an annual basis. Centennial has an uncommitted long-term master shelf agreement on behalf of its subsidiaries that allows for borrowings of up to $200 million. Under the master shelf agreement, $150 million was outstanding at December 31, 2000 and none was outstanding at December 31, 1999. The amount outstanding is presented in senior notes in the preceding table. Under the revolving lines of credit, the company and certain subsidiaries have $48.2 million available as of December 31, 2000. Amounts outstanding under the revolving lines of credit were $46.3 million and $45.9 million at December 31, 2000 and 1999, respectively. The amounts of scheduled long-term debt maturities for the five years following December 31, 2000 aggregate $19.6 million in 2001; $50.4 million in 2002; $282.7 million in 2003; $21.6 million in 2004 and $69.9 million in 2005. Substantially all of the company's electric and natural gas distribution properties, with certain exceptions, are subject to the lien of its Indenture of Mortgage. Under the terms and conditions of the Indenture, the company could have issued approximately $295 million of additional first mortgage bonds at December 31, 2000. Certain other debt instruments of the company and its subsidiaries contain restrictive covenants, all of which the company and its subsidiaries are in compliance with at December 31, 2000. NOTE 6 PREFERRED STOCKS Preferred stocks at December 31 are as follows: 2000 1999 (Dollars in thousands) Authorized: Preferred -- 500,000 shares, cumulative, par value $100, issuable in series Preferred stock A -- 1,000,000 shares, cumulative, without par value, issuable in series (none outstanding) Preference -- 500,000 shares, cumulative, without par value, issuable in series (none outstanding) Outstanding: Subject to mandatory redemption -- Preferred -- 5.10% Series -- 15,000 shares in 2000 and 16,000 shares in 1999 $ 1,500 $ 1,600 Other preferred stock -- 4.50% Series -- 100,000 shares 10,000 10,000 4.70% Series -- 50,000 shares 5,000 5,000 15,000 15,000 Total preferred stocks 16,500 16,600 Less sinking fund requirements 100 100 Net preferred stocks $16,400 $16,500 The preferred stocks outstanding are subject to redemption, in whole or in part, at the option of the company with certain limitations on 30 days notice on any quarterly dividend date on certain series of preferred stock. The company is obligated to make annual sinking fund contributions to retire the 5.10% Series preferred stock. The redemption prices and sinking fund requirements, where applicable, are summarized below: Redemption Sinking Fund Series Price (a) Shares Price (a) Preferred stocks: 4.50% $105 (b) --- --- 4.70% $102 (b) --- --- 5.10% $102 1,000 (c) $100 (a) Plus accrued dividends. (b) These series are redeemable at the sole discretion of the company. (c) Annually on December 1, if tendered. In the event of a voluntary or involuntary liquidation, all preferred stock series holders are entitled to $100 per share, plus accrued dividends. The aggregate annual sinking fund amount applicable to preferred stock subject to mandatory redemption for each of the five years following December 31, 2000, is $100,000. NOTE 7 COMMON STOCK At the Annual Meeting of Stockholders held in April 1999, the company's common stockholders approved an amendment to the Certificate of Incorporation increasing the authorized number of common shares from 75 million shares to 150 million shares and reducing the par value of the common stock from $3.33 per share to $1.00 per share. In May 1998, the company's Board of Directors approved a three-for-two common stock split effected in the form of a 50 percent common stock dividend. The additional shares of common stock were distributed on July 13, 1998, to common stockholders of record on July 3, 1998. Common stock information appearing in the accompanying Consolidated Statements of Income and Notes to Consolidated Financial Statements give retroactive effect to stock split. The company's Automatic Dividend Reinvestment and Stock Purchase Plan (Stock Purchase Plan) provides participants the opportunity to invest all or a portion of their cash dividends in shares of the company's common stock and to make optional cash payments of up to $5,000 per month for the same purpose. Holders of all classes of the company's capital stock, legal residents in any of the 50 states, and beneficial owners, whose shares are held by brokers or other nominees through participation by their brokers or nominees, are eligible to participate in the Stock Purchase Plan. The company's Tax Deferred Compensation Savings Plan(s) (K-Plan(s)), which were merged effective January 1, 1999, pursuant to Section 401(k) of the Internal Revenue Code are funded with the company's common stock. Since January 1, 1989, the Stock Purchase Plan and K-Plan(s) have been funded primarily by the purchase of shares of common stock on the open market, except for a portion of 1997 where shares of authorized but unissued common stock were used to fund the Stock Purchase Plan and K-Plan(s) and from October 1, 1998 through March 31, 1999, when shares of authorized but unissued common stock were used to fund the Stock Purchase Plan. At December 31, 2000, there were 8.1 million shares of common stock reserved for original issuance under the Stock Purchase Plan and K- Plan. In November 1998, the company's Board of Directors declared, pursuant to a stockholders' rights plan, a dividend of one preference share purchase right (right) for each outstanding share of the company's common stock. Each right becomes exercisable, upon the occurrence of certain events, for one one-thousandth of a share of Series B Preference Stock of the company, without par value, at an exercise price of $125 per one one-thousandth, subject to certain adjustments. The rights are currently not exercisable and will be exercisable only if a person or group (acquiring person) either acquires ownership of 15 percent or more of the company's common stock or commences a tender or exchange offer that would result in ownership of 15 percent or more. In the event the company is acquired in a merger or other business combination transaction or 50 percent or more of its consolidated assets or earnings power are sold, each right entitles the holder to receive, upon the exercise thereof at the then current exercise price of the right multiplied by the number of one one-thousandth of a Series B Preference Stock for which a right is then exercisable, in accordance with the terms of the rights agreement, such number of shares of common stock of the acquiring person having a market value of twice the then current exercise price of the right. The rights, which expire on December 31, 2008, are redeemable in whole, but not in part, for a price of $.01 per right, at the company's option at any time until any acquiring person has acquired 15 percent or more of the company's common stock. The company has stock option plans for directors, key employees and employees, which grant options to purchase shares of the company's stock. The company accounts for these option plans in accordance with APB Opinion No. 25 under which no compensation expense has been recognized. The option exercise price is the market value of the stock on the date of grant. Options granted to the key employees automatically vest after nine years, but the plan provides for accelerated vesting based on the attainment of certain performance goals or upon a change in control of the company. Options granted to directors and employees vest at date of grant and three years after date of grant, respectively, and expire ten years after the date of grant. In addition, the company has granted restricted stock awards under a long-term incentive plan, deferred compensation agreement and a restricted stock agreement totaling 348,021 shares, 105,250 shares and 21,135 shares in 2000, 1999 and 1998, respectively. The restricted stock awards granted vest to the participants at various times ranging from three years to nine years from date of issuance but certain grants may vest early based upon the attainment of certain performance goals or upon a change in control of the company. The weighted average grant date fair value of the restricted stock grants was $20.81, $22.91 and $23.24 in 2000, 1999 and 1998, respectively. Compensation expense recognized for restricted stock grants was $1.6 million, $722,000 and $123,000 in 2000, 1999 and 1998, respectively. Under the stock option plans and long-term incentive plan, the company is authorized to grant options and restricted stock for up to 4.3 million shares of common stock and has granted options and restricted stock on 2.1 million shares through December 31, 2000. Had the company recorded compensation expense for the fair value of options granted consistent with SFAS No. 123, "Accounting for Stock- Based Compensation," net income would have been reduced on a pro forma basis by $529,000 in 2000, $498,000 in 1999, and $820,000 in 1998. On a pro forma basis, there would have been no effect on basic earnings per share for 2000, and diluted earnings per share would have been reduced by $.01. On a pro forma basis, basic and diluted earnings per share for 1999 and 1998 would have been reduced by $.01 and $.02, respectively. A summary of the status of the stock option plans at December 31, 2000, 1999 and 1998, and changes during the years then ended are as follows: 2000 1999 1998 Weighted Weighted Weighted Average Average Average Exercise Exercise Exercise Shares Price Shares Price Shares Price Balance at beginning of year 1,427,262 $19.46 1,516,808 $19.17 594,180 $12.07 Granted 74,000 20.54 22,500 23.31 1,225,920 21.12 Forfeited (84,135) 21.18 (57,966) 20.38 (37,875) 21.05 Exercised (192,168) 11.84 (54,080) 11.95 (265,417) 11.98 Balance at end of year 1,224,959 20.61 1,427,262 19.46 1,516,808 19.17 Exercisable at end of year 129,763 $18.11 301,681 $13.89 333,261 $12.94 Exercise prices on options outstanding at December 31, 2000, range from $10.50 to $23.84 with a weighted average remaining contractual life of approximately 7 years. The fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model. The weighted average fair value of the options granted and the assumptions used to estimate the fair value of options are as follows: 2000 1999 1998 Fair value of options at grant date $ 5.07 $ 4.82 $ 2.40 Weighted average risk-free interest rate 6.76% 5.98% 4.78% Weighted average expected price volatility 23.55% 22.03% 16.27% Weighted average expected dividend yield 3.84% 4.22% 5.13% Expected life in years 7 7 7 NOTE 8 INCOME TAXES Income tax expense is summarized as follows: Years ended December 31, 2000 1999 1998 (In thousands) Current: Federal $27,865 $29,574 $28,256 State 5,188 3,874 5,880 Foreign 67 158 605 33,120 33,606 34,741 Deferred: Income taxes -- Federal 29,323 12,902 (14,214) State 8,060 3,690 (2,067) Investment tax credit (853) (888) (975) 36,530 15,704 (17,256) Total income tax expense $69,650 $49,310 $17,485 Components of deferred tax assets and deferred tax liabilities recognized in the company's Consolidated Balance Sheets at December 31 are as follows: 2000 1999 (In thousands) Deferred tax assets: Accrued pension costs $ 10,325 $ 10,898 Regulatory matters 7,650 14,562 Accrued land reclamation 1,941 2,803 Deferred investment tax credit 1,697 2,028 Other 18,213 16,892 Total deferred tax assets 39,826 47,183 Deferred tax liabilities: Depreciation and basis differences on property, plant and equipment 264,635 218,355 Basis differences on natural gas and oil producing properties 36,763 17,163 Regulatory matters 3,554 6,785 Other 7,826 3,051 Total deferred tax liabilities 312,778 245,354 Net deferred income tax liability $(272,952)$(198,171) The following table reconciles the change in the net deferred income tax liability from December 31, 1999, to December 31, 2000, to the deferred income tax expense included in the Consolidated Statements of Income: 2000 (In thousands) Net change in deferred income tax liability from the preceding table $ 74,781 Change in tax effects of income tax-related regulatory assets and liabilities (150) Deferred taxes associated with acquisitions (38,101) Deferred income tax expense for the period $ 36,530 Total income tax expense differs from the amount computed by applying the statutory federal income tax rate to income before taxes.

The company's operations are conducted through six business segments. Substantially all of the company's operations are located within the United States. The electric business generates, transmits and distributes electricity and the natural gas distribution business distributes natural gas. These operations also supply related value-added products and services in the Northern Great Plains. The utility services business consists of a diversified infrastructure construction company specializing in electric, natural gas and telecommunication utility construction as well as interior industrial electrical, exterior lighting and traffic signalization. Utility services has engineering, design and build capability and provides related specialty equipment sales and rental services throughout most of the United States. The pipeline and energy services business provides natural gas transportation, underground storage and gathering services through regulated and nonregulated pipeline systems and provides energy-related marketing and management services. The natural gas and oil production business is engaged in natural gas and oil acquisition, exploration and production activities primarily in the Rocky Mountain region of the United States and in the Gulf of Mexico. The construction materials and mining business mines and markets aggregates and related value-added construction materials products and services in the western United States, including Alaska and Hawaii, and it also operates lignite coal mines in Montana and North Dakota. On September 28, 2000, the company announced an agreement to sell its coal operations to Westmoreland Coal Company for $28.8 million cash, excluding final settlement cost adjustments. The agreement is subject to various closing conditions and therefore will not be finalized unless and until the parties are satisfied that those conditions are met. Segment information follows the same accounting policies as described in the Summary of Significant Accounting Policies.

(c) Includes, in the case of electric and natural gas distribution property, allocations of common utility property. (d) Corporate assets consist of assets not directly assignable to a business segment (i.e., cash and cash equivalents, certain accounts receivable and other miscellaneous current and deferred assets). - ------------------------------------------------------------- Capital expenditures for 2000, 1999 and 1998, related to acquisitions, in the preceding table include the following noncash transactions: issuance of the company's equity securities and the conversion of a note receivable to purchase consideration of $132.1 million in 2000; the issuance of the company's equity securities of $77.5 million in 1999; and the issuance of the company's equity securities, less treasury stock acquired, in 1998 of $138.8 million. NOTE 10 ACQUISITIONS In 2000, the company acquired a number of businesses, none of which was individually material, including construction materials and mining businesses with operations in Alaska, California, Montana and Oregon; a coal bed natural gas development operation based in Colorado with related oil and gas leases and properties in Montana and Wyoming; utility services businesses based in California, Colorado, Montana and Ohio; a natural gas distribution business serving southeastern North Dakota and western Minnesota; and an energy services company based in Texas. The total purchase consideration for these businesses, consisting of the company's common stock, cash and the conversion of a note receivable to purchase consideration was $286.0 million. On April 1, 2000, WBI Production, Inc., an indirect wholly owned subsidiary of the company, purchased substantially all of the assets of Preston Reynolds & Co., Inc. (Preston), a coal bed natural gas development operation, as previously discussed. Pursuant to the asset purchase and sale agreement, Preston may, but is not obligated to purchase, acquire and own an undivided 25 percent working interest (Seller's Option Interest) in oil and gas leases or properties acquired and/or generated by Redstone Gas Partners, LLC, a limited liability company controlled by the company. The Seller's Option Interest commences April 1, 2002 and terminates six months thereafter and requires Preston to pay WBI Production 25 percent of its capital investment, during the two year period subsequent to April 1, 2000, in the oil and gas leases or properties. WBI Production has the right, but not the obligation, to purchase Seller's Option Interest from Preston for an amount as specified in the agreement. In 1999, the company acquired a number of businesses, none of which was individually material, including construction materials and mining companies with operations in California, Montana, Oregon and Wyoming; and utility services companies based in Montana and Oregon. The total purchase consideration for these businesses, consisting of the company's common stock and cash, was $81.9 million. In March 1998, the company acquired Morse Bros., Inc. and S2 - F Corp., privately held construction materials companies located in Oregon's Willamette Valley. The purchase consideration for such companies consisted of $98.2 million of the company's common stock and cash. Morse Bros., Inc. sells aggregate, ready-mixed concrete, asphalt, prestressed concrete and construction services in the Willamette Valley from Portland to Eugene. S2 - F Corp. sells aggregate and construction services. The company also acquired a number of other businesses in 1998, none of which was individually material, including construction materials and mining businesses in Oregon, utility services construction and engineering businesses in California and Montana and a natural gas marketing business in Kentucky. The total purchase consideration, consisting of the company's common stock and cash, for these businesses was $62.7 million. The above acquisitions were accounted for under the purchase method of accounting and accordingly, the acquired assets and liabilities assumed have been preliminarily recorded at their respective fair values as of the date of acquisition. Final fair market values are pending the completion of the review of the relevant assets, liabilities and issues identified as of the acquisition date on certain of the above acquisitions. The results of operations of the acquired businesses are included in the financial statements since the date of each acquisition. Pro forma financial amounts reflecting the effects of the above acquisitions are not presented as such acquisitions were not material to the company's financial position or results of operations. NOTE 11 EMPLOYEE BENEFIT PLANS The company has noncontributory defined benefit pension plans and other postretirement benefit plans. There were no additional minimum pension liabilities required to be recognized as of December 31, 2000 and 1999. Changes in benefit obligation and plan assets for the years ended December 31 are as follows: Other Pension Postretirement Benefits Benefits 2000 1999 2000 1999 (In thousands) Change in benefit obligation: Benefit obligation at beginning of year $180,997 $187,665 $65,939 $ 70,338 Service cost 4,561 4,894 1,307 1,451 Interest cost 14,174 12,573 4,946 4,720 Plan participants' contributions --- --- 677 617 Amendments 7,111 3,612 --- 3,691 Actuarial (gain) loss 9,535 (17,134) 928 (11,047) Benefits paid (15,498) (10,613) (4,330) (3,831) Benefit obligation at end of year 200,880 180,997 69,467 65,939 Change in plan assets: Fair value of plan assets at beginning of year 276,459 251,194 47,147 39,543 Actual return on plan assets 875 35,874 (1,078) 5,223 Employer contribution 28 4 4,630 5,595 Plan participants' contributions --- --- 677 617 Benefits paid (15,498) (10,613) (4,330) (3,831) Fair value of plan assets at end of year 261,864 276,459 47,046 47,147 Funded status 60,984 95,462 (22,421) (18,792) Unrecognized actuarial gain (76,417) (108,593) (15,228) (21,299) Unrecognized prior service cost 16,271 10,206 --- --- Unrecognized net transition obligation (asset) (3,387) (4,402) 28,532 30,910 Accrued benefit cost $ (2,549) $ (7,327) $(9,117) $ (9,181) Weighted average assumptions for the company's pension and other postretirement benefit plans as of December 31 are as follows: Other Pension Postretirement Benefits Benefits 2000 1999 2000 1999 Discount rate 7.50% 7.75% 7.50% 7.75% Expected return on plan assets 8.50% 8.50% 7.50% 7.50% Rate of compensation increase 5.00% 5.00% 5.00% 5.00% Health care rate assumptions for the company's other postretirement benefit plans as of December 31 are as follows: 2000 1999 Health care trend rate 6.00%-7.50% 6.00%-8.00% Health care cost trend rate - ultimate 5.00%-6.00% 5.00%-6.00% Year in which ultimate trend rate achieved 1999-2004 1999-2004 Components of net periodic benefit cost for the company's pension and other postretirement benefit plans are as follows: Other Pension Postretirement Benefits Benefits Years ended December 31, 2000 1999 1998 2000 1999 1998 (In thousands) Components of net periodic benefit cost: Service cost $ 4,561 $ 4,894 $ 4,509 $1,307 $1,451 $1,502 Interest cost 14,174 12,573 12,248 4,946 4,720 4,848 Expected return on assets (19,927) (17,489) (15,892) (3,267) (2,807) (2,395) Amortization of prior service cost 1,047 842 848 --- --- --- Recognized net actuarial gain (2,907) (995) (621) (799) (200) (169) Settlement gain (700) --- --- --- --- --- Amortization of net transition obligation (asset) (997) (997) (994) 2,378 2,377 2,458 Net periodic benefit cost (income) (4,749) (1,172) 98 4,565 5,541 6,244 Less amount capitalized (397) (87) 79 369 463 628 Net periodic benefit expense (income) $ (4,352) $(1,085) $ 19 $4,196 $5,078 $5,616 The company has other postretirement benefit plans including health care and life insurance. The plans underlying these benefits may require contributions by the employee depending on such employee's age and years of service at retirement or the date of retirement. The accounting for the health care plan anticipates future cost-sharing changes that are consistent with the company's expressed intent to generally increase retiree contributions each year by the excess of the expected health care cost trend rate over 6 percent. Assumed health care cost trend rates may have a significant effect on the amounts reported for the health care plans. A one percentage point change in the assumed health care cost trend rates would have the following effects at December 31, 2000: 1 Percentage 1 Percentage Point Increase Point Decrease (In thousands) Effect on total of service and interest cost components $ 216 $ (196) Effect on postretirement benefit obligation $ 2,716 $(2,627) In addition to company-sponsored plans, certain union employees of Hawaiian Cement, an indirect wholly owned subsidiary of the company, are covered under a multi-employer defined benefit plan administered by a union. Amounts contributed to the multi-employer plan were $947,000, $818,000 and $755,000 in 2000, 1999 and 1998, respectively. The company has an unfunded, nonqualified benefit plan for executive officers and certain key management employees that provides for defined benefit payments upon the employee's retirement or to their beneficiaries upon death for a 15-year period. Investments consist of life insurance carried on plan participants which is payable to the company upon the employee's death. The cost of these benefits was $3.5 million, $3.3 million and $2.7 million in 2000, 1999 and 1998, respectively. The company sponsors various defined contribution plans for eligible employees. Costs incurred by the company under these plans were $6.1 million in 2000, $4.4 million in 1999 and $3.1 million in 1998. The costs incurred in each year reflect additional participants as a result of business acquisitions. NOTE 12 JOINTLY OWNED FACILITIES The consolidated financial statements include the company's 22.7 percent and 25.0 percent ownership interests in the assets, liabilities and expenses of the Big Stone Station and the Coyote Station, respectively. Each owner of the Big Stone and Coyote stations is responsible for financing its investment in the jointly owned facilities. The company's share of the Big Stone Station and Coyote Station operating expenses is reflected in the appropriate categories of operating expenses in the Consolidated Statements of Income. At December 31, the company's share of the cost of utility plant in service and related accumulated depreciation for the stations was as follows: 2000 1999 (In thousands) Big Stone Station: Utility plant in service $ 50,029 $ 49,889 Less accumulated depreciation 31,381 29,611 $ 18,648 $ 20,278 Coyote Station: Utility plant in service $122,111 $121,919 Less accumulated depreciation 63,741 60,350 $ 58,370 $ 61,569 NOTE 13 REGULATORY MATTERS AND REVENUES SUBJECT TO REFUND In June 1995, Williston Basin Interstate Pipeline Company (Williston Basin), an indirect wholly owned subsidiary of the company, filed a general rate increase application with the Federal Energy Regulatory Commission (FERC). As a result of FERC orders issued after Williston Basin's application was filed, Williston Basin filed revised base rates in December 1995 with the FERC. Williston Basin began collecting such increase effective January 1, 1996, subject to refund. In July 1998, the FERC issued an order which addressed various issues including storage cost allocations, return on equity and throughput. In August 1998, Williston Basin requested rehearing of such order. In June 1999, the FERC issued an order approving and denying various issues addressed in Williston Basin's rehearing request, and also remanding the return on equity issue to an Administrative Law Judge for further proceedings. In July 1999, Williston Basin requested rehearing of certain issues which were contained in the June 1999 FERC order. In September 1999, the FERC granted Williston Basin's request for rehearing with respect to the return on equity issue but also ordered Williston Basin to issue interim refunds prior to the final determination in this proceeding. As a result, in October 1999, Williston Basin issued refunds to its customers totaling $11.3 million, all from amounts which had previously been reserved. In December 1999, a hearing was held before the FERC regarding the return on equity issue. On April 27, 2000, the Administrative Law Judge issued an Initial Decision regarding the remanded return on equity issue. On August 15, 2000, Williston Basin filed a stipulation and agreement for the purpose of resolving the rate and refund matters at issue with the FERC. On November 21, 2000, the FERC issued its order accepting the August 15, 2000 stipulation and agreement. As a result, on December 28, 2000, Williston Basin issued refunds to its customers totaling $13.0 million, all from amounts which had previously been reserved. In December 1999, Williston Basin filed a general natural gas rate change application with the FERC. Williston Basin began collecting such rates effective June 1, 2000, subject to refund. Reserves have been provided for a portion of the revenues that have been collected subject to refund with respect to pending regulatory proceedings and to reflect future resolution of certain issues with the FERC. Based on the November 21, 2000 FERC order referenced above, Williston Basin, in the fourth quarter of 2000, determined that reserves it had previously established exceeded its expected refund obligation and, accordingly, reversed reserves and recognized in income $6.7 million after tax. Williston Basin, in the second quarter of 1999, determined that reserves it had previously established in relation to a 1992 general natural gas rate change application and the 1995 general rate increase application exceeded its expected refund obligation and, accordingly, reversed reserves and recognized in income $4.4 million after tax. Williston Basin believes that its remaining reserves are adequate based on its assessment of the ultimate outcome of the application filed in December 1999. NOTE 14 COMMITMENTS AND CONTINGENCIES Litigation In March 1997, 11 natural gas producers filed suit in North Dakota Northwest Judicial District Court (North Dakota District Court) against Williston Basin and the company. The natural gas producers had processing agreements with Koch Hydrocarbon Company (Koch). Williston Basin and the company had natural gas purchase contracts with Koch. The natural gas producers alleged they were entitled to damages for the breach of Williston Basin's and the company's contracts with Koch although no specific damages were stated. A similar suit was filed by Apache Corporation (Apache) and Snyder Oil Corporation (Snyder) in North Dakota District Court in December 1993. The North Dakota Supreme Court in December 1999 affirmed the North Dakota District Court decision dismissing Apache's and Snyder's claims against Williston Basin and the company. Based in part upon the decision of the North Dakota Supreme Court affirming the dismissal of the claims brought by Apache and Snyder, Williston Basin and the company filed motions for summary judgment to dismiss the claims of the 11 natural gas producers. The motions for summary judgment were granted by the North Dakota District Court on July 3, 2000. The company is awaiting entry of a final judgment on the July 3, 2000 order granting the motions for summary judgment. In July 1996, Jack J. Grynberg (Grynberg) filed suit in United States District Court for the District of Columbia (U.S. District Court) against Williston Basin and over 70 other natural gas pipeline companies. Grynberg, acting on behalf of the United States under the Federal False Claims Act, alleged improper measurement of the heating content or volume of natural gas purchased by the defendants resulting in the underpayment of royalties to the United States. In March 1997, the U.S. District Court dismissed the suit without prejudice and the dismissal was affirmed by the D.C. Circuit Court in October 1998. In June 1997, Grynberg filed a similar Federal False Claims Act suit against Williston Basin and Montana-Dakota and filed over 70 other separate similar suits against natural gas transmission companies and producers, gatherers, and processors of natural gas. In April 1999, the United States Department of Justice decided not to intervene in these cases. In response to a motion filed by Grynberg, the Judicial Panel on Multidistrict Litigation consolidated all of these cases in the Federal District Court of Wyoming (Federal District Court). Oral argument on motions to dismiss was held before the Federal District Court on March 17, 2000. Williston Basin and Montana-Dakota are awaiting a decision from the Federal District Court. The Quinque Operating Company (Quinque), on behalf of itself and subclasses of gas producers, royalty owners and state taxing authorities, instituted a legal proceeding in State District Court for Stevens County, Kansas, against over 200 natural gas transmission companies and producers, gatherers, and processors of natural gas, including Williston Basin and Montana-Dakota. The complaint, which was served on Williston Basin and Montana-Dakota in September 1999, contains allegations of improper measurement of the heating content and volume of all natural gas measured by the defendants other than natural gas produced from federal lands. In response to a motion filed by the defendants in this suit, the Judicial Panel on Multidistrict Litigation transferred the suit to the Federal District Court for inclusion in the pretrial proceedings of the Grynberg suit. Williston Basin and Montana-Dakota believe the claims of Grynberg and Quinque are without merit and intend to vigorously contest these suits. The company is also involved in other legal actions in the ordinary course of its business. Although the outcomes of any such legal actions cannot be predicted, management believes that there is no pending legal proceeding against or involving the company, except those discussed above, for which the outcome is likely to have a material adverse effect upon the company's financial position or results of operations. Environmental matters In December 2000, Morse Bros., Inc. (MBI), an indirect wholly owned subsidiary of the company, was named by the United States Environmental Protection Agency (EPA) as a Potentially Responsible Party in connection with the cleanup of a commercial property site, now owned by MBI, and part of the Portland, Oregon, Harbor Superfund Site. Sixty- eight other parties were also named in this administrative action. The EPA wants responsible parties to share in the cleanup of sediment contamination in the Willamette River. Based upon a review of the Portland Harbor sediment contamination evaluation by the Oregon State Department of Environmental Quality and other information available, MBI does not believe it is a Responsible Party. In addition, MBI intends to seek indemnity for any and all liabilities incurred in relation to the above matters from Georgia-Pacific West, Inc., the seller of the commercial property site to MBI, pursuant to the terms of their sale agreement. Electric purchased power commitments Through October 31, 2006, Montana-Dakota has contracted to purchase 66,400 kW of participation power annually from Basin Electric Power Cooperative. In addition, Montana-Dakota, under a power supply contract through December 31, 2006, is purchasing up to 55,000 kW of capacity annually from Black Hills Power and Light Company.

Accordingly, quarterly financial information may not be indicative of results for a full year. NOTE 16 NATURAL GAS AND OIL ACTIVITIES (UNAUDITED) Fidelity Exploration & Production Company (Fidelity), an indirect wholly owned subsidiary of the company, is involved in the acquisition, exploration, development and production of natural gas and oil resources. Fidelity's operations include the acquisition of producing properties with potential development opportunities, exploratory drilling and the operation of natural gas production properties. Fidelity shares revenues and expenses from the development of specified properties located primarily in the Rocky Mountain region of the United States and in the Gulf of Mexico in proportion to its interests. Fidelity owns in fee or holds natural gas leases for the properties it operates in Colorado, Montana and North Dakota. These rights are in the Bonny Field located in eastern Colorado, the Cedar Creek Anticline in southeastern Montana and southwestern North Dakota, and in the Bowdoin area located in north-central Montana. In 2000, coal bed natural gas reserves in the Powder River Basin of Wyoming and Montana were acquired. These acquisitions include over 210,000 net acres under lease. The information that follows includes the company's proportionate share of all its natural gas and oil interests held by Fidelity. The following table sets forth capitalized costs and accumulated depreciation, depletion and amortization related to natural gas and oil producing activities at December 31: 2000 1999 1998 (In thousands) Subject to amortization $416,881 $319,448 $266,301 Not subject to amortization 94,856 23,464 22,153 Total capitalized costs 511,737 342,912 288,454 Less accumulated depreciation, depletion and amortization 155,198 129,211 111,472 Net capitalized costs $356,539 $213,701 $176,982 NOTE: Net capitalized costs as of December 31, 1998, reflect noncash write-downs of the company's natural gas and oil properties as discussed in Note 1. Capital expenditures, including those not subject to amortization, related to natural gas and oil producing activities are as follows: Years ended December 31, 2000 1999 1998 (In thousands) Acquisitions $ 68,858 $ 30,842 $ 63,419 Exploration 34,839 11,010 15,976 Development 69,051 21,822 21,148 Total capital expenditures $172,748 $ 63,674 $100,543 The following summary reflects income resulting from the company's operations of natural gas and oil producing activities, excluding corporate overhead and financing costs: Years ended December 31, 2000 1999 1998 (In thousands) Revenues $128,217 $ 75,327 $ 61,831 Production costs 33,919 25,402 19,419 Depreciation, depletion and amortization 26,739 19,136 23,050 Write-downs of natural gas and oil properties (Note 1) --- --- 66,000 Pretax income (loss) 67,559 30,789 (46,638) Income tax expense (benefit) 25,835 11,815 (19,268) Results of operations for producing activities $ 41,724 $ 18,974 $(27,370) The following table summarizes the company's estimated quantities of proved natural gas and oil reserves at December 31, 2000, 1999 and 1998, and reconciles the changes between these dates. Estimates of economically recoverable natural gas and oil reserves and future net revenues therefrom are based upon a number of variable factors and assumptions. For these reasons, estimates of economically recoverable reserves and future net revenues may vary from actual results. 2000 1999 1998 Natural Natural Natural Gas Oil Gas Oil Gas Oil (In thousands of Mcf/barrels) Proved developed and undeveloped reserves: Balance at beginning of year 268,900 14,700 243,600 11,500 184,900 14,900 Production (29,200) (1,900) (24,700) (1,800) (20,700) (1,900) Extensions and discoveries 51,300 1,600 21,800 800 21,300 200 Purchases of proved reserves 23,200 100 38,200 700 56,600 2,000 Sales of reserves in place --- (100) (9,300) (400) (100) --- Revisions to previous estimates due to improved secondary recovery techniques and/or changed economic conditions (4,400) 700 (700) 3,900 1,600 (3,700) Balance at end of year 309,800 15,100 268,900 14,700 243,600 11,500 Proved developed reserves: January 1, 1998 163,800 14,500 December 31, 1998 193,000 10,700 December 31, 1999 213,400 13,300 December 31, 2000 263,400 14,200 All of the company's interests in natural gas and oil reserves are located in the United States and in the Gulf of Mexico. The standardized measure of the company's estimated discounted future net cash flows of total proved reserves associated with its various natural gas and oil interests at December 31 is as follows: 2000 1999 1998 (In thousands) Future net cash flows before income taxes $2,349,500 $492,000 $246,700 Future income tax expense 827,000 131,500 40,500 Future net cash flows 1,522,500 360,500 206,200 10% annual discount for estimated timing of cash flows 601,200 131,400 81,100 Discounted future net cash flows relating to proved natural gas and oil reserves $ 921,300 $229,100 $125,100 The following are the sources of change in the standardized measure of discounted future net cash flows by year: 2000 1999 1998 (In thousands) Beginning of year $229,100 $125,100 $139,000 Net revenues from production (94,300) (49,900) (42,400) Change in net realization 861,700 123,100 (70,500) Extensions, discoveries and improved recovery, net of future production-related costs 288,700 33,500 18,200 Purchases of proved reserves 93,200 57,700 51,000 Sales of reserves in place (1,500) (14,700) (100) Changes in estimated future development costs, net of those incurred during the year 3,400 (9,800) (16,600) Accretion of discount 31,200 16,700 18,600 Net change in income taxes (412,300) (59,800) 30,100 Revisions of previous quantity estimates (79,200) 7,400 (1,600) Other 1,300 (200) (600) Net change 692,200 104,000 (13,900) End of year $921,300 $229,100 $125,100 The estimated discounted future cash inflows from estimated future production of proved reserves were computed using year-end natural gas prices and oil prices except in those instances where future natural gas or oil sales are covered by physical or derivative contract terms providing for higher or lower amounts. Future development and production costs attributable to proved reserves were computed by applying year-end costs to be incurred in producing and further developing the proved reserves. Future income tax expenses were computed by applying statutory tax rates (adjusted for permanent differences and tax credits) to estimated net future pretax cash flows. The standardized measure of discounted future net cash flows does not purport to represent the fair market value of natural gas and oil properties. There are significant uncertainties inherent in estimating quantities of proved reserves and in projecting rates of production and the timing and amount of future costs. In addition, future realization of natural gas and oil prices over the remaining reserve lives may vary significantly from current prices.
