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 accounting principles generally accepted in the United States 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. /s/ Martin A.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS MDU RESOURCES GROUP, INC. 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 10. 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 is 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. Prior to the sale of the company's coal operations as discussed in Note 10, intercompany coal sales, which were made at prices approximately the same as those charged to others, and the related utility fuel purchases are not eliminated in accordance with the provisions of SFAS No. 71. All other significant intercompany balances and transactions have been eliminated in consolidation. Allowance for doubtful accounts The company's allowance for doubtful accounts as of December 31, 2001 and 2000, was $5.8 million and $4.1 million, respectively. 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 $6.6 million, $5.2 million and $1.7 million in 2001, 2000 and 1999, respectively. Generally, 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 was being amortized on a straight-line basis over estimated useful lives for recorded goodwill in place at June 30, 2001. However, Statement of Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets" (SFAS No. 142), which the company adopted as of January 1, 2002, as discussed later in Note 1, requires the discontinuance of goodwill amortization for the company's recorded goodwill at June 30, 2001, on January 1, 2002. Goodwill acquired after June 30, 2001, was subject immediately to the nonamortization provisions of SFAS No. 142. Goodwill, net of accumulated amortization, was $174.2 million and $91.4 million as of December 31, 2001 and 2000, respectively. Goodwill is included in deferred charges and other assets. Goodwill amortization expense was $4.8 million, $7.0 million and $2.0 million for 2001, 2000 and 1999, respectively. 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 and annually for goodwill as required by SFAS No. 142. 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 2000. The amount related to this impairment is included in depreciation, depletion and amortization. Excluding this impairment, no other long-lived assets or intangibles have been impaired and accordingly, no other impairment losses have been recorded in 2001, 2000 and 1999. Unforeseen events and changes in circumstances could require the recognition of other impairment losses at some future date. Impairment testing of natural gas and oil properties 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 based on single point in time spot market prices, as mandated under the rules of the Securities and Exchange Commission, and the lower of cost or fair value of unproved properties. Future net revenue is estimated based on end-of-quarter spot market 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 unless subsequent price changes eliminate or reduce an indicated write-down. Due to abnormally low spot natural gas prices that existed on the last trading day of the third quarter of 2001, the company's capitalized costs under the full-cost method of accounting exceeded the full-cost ceiling at September 30, 2001. The lower natural gas prices were largely attributable to a sharp decline in nationwide spot market prices, especially natural gas prices in the Rocky Mountain region, over a relatively short period of time following the terrorist attacks on New York and Washington, D.C. on September 11, 2001, and prior to October 1, 2001. Oil prices likewise experienced a sharp drop during this same period. The company believes the decline in natural gas prices did not reflect the economics of its production assets in that natural gas prices actually being received by the company at the end of the third quarter of 2001 were significantly higher than the spot market prices at that time. In addition, historic natural gas prices have also generally been much higher and only a small portion of the company's natural gas is sold using spot market pricing. As of September 30, 2001, the capitalized costs exceeded the full-cost ceiling and would have resulted in a write-down of the company's natural gas and oil properties in the amount of approximately $32 million after-tax. However, subsequent to September 30, 2001, natural gas prices both nationwide and in the Rocky Mountain region increased significantly, thereby eliminating the need for a write-down of the company's natural gas and oil producing properties. At December 31, 2001, the company's full-cost ceiling exceeded the company's capitalized cost. However, sustained downward movements in natural gas and oil prices subsequent to December 31, 2001, could result in a future write-down of the company's natural gas and oil properties. 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 $28.6 million and $11.0 million at December 31, 2001 and 2000, respectively. The remainder of natural gas in underground storage is included in property, plant and equipment and was $43.1 million and $43.6 million at December 31, 2001 and 2000, respectively. Inventories Inventories, other than natural gas in underground storage for the company's regulated operations, consist primarily of materials and supplies of $22.5 million and $20.4 million, aggregates held for resale of $31.1 million and $22.7 million and other inventories of $13.1 million and $9.9 million as of December 31, 2001 and 2000, respectively. These inventories are stated at the lower of average cost or market. Revenue recognition Revenue is recognized when the earnings process is complete, as evidenced by an agreement between the customer and the company, when delivery has occurred or services have been rendered, when the fee is fixed or determinable and when collection is probable. The company recognizes utility revenue each month based on the services provided to all utility customers during the month. The company recognizes construction contract revenue at its construction businesses using the percentage-of-completion method as discussed below. 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. Percentage-of-completion method The company recognizes construction contract revenue from fixed price and modified fixed price construction contracts at its construction businesses using the percentage-of-completion method, measured by the percentage of costs incurred to date to estimated total costs for each contract. Costs in excess of billings on uncompleted contracts of $29.7 million and $13.9 million for the years ending December 31, 2001 and 2000, respectively, represents revenues recognized in excess of amounts billed and is included in accounts receivable. Billings in excess of costs on uncompleted contracts of $17.3 million and $8.0 million for the years ending December 31, 2001 and 2000, respectively, represents billings in excess of revenues recognized and are included in accounts payable. Also included in accounts receivable are amounts representing balances billed but not paid by customers under retainage provisions in contracts which amounted to $20.5 million and $13.7 million as of December 31, 2001 and 2000, respectively. Advertising The company expenses advertising costs as incurred and the amount of advertising expense for the years 2001, 2000 and 1999, was $2.9 million, $2.0 million and $1.3 million, respectively. Natural gas costs recoverable or refundable 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. Natural gas costs refundable through rate adjustments amounted to $27.7 million and $8.8 million for the years ended December 31, 2001 and 2000, respectively, and are included in other accrued liabilities. 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 accrued liabilities. 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. For the years ending December 31, 2001 and 1999, 150,630 shares and 76,500 shares, respectively, with an average exercise price of $36.86 and $23.44, respectively, attributable to the exercise of outstanding options were excluded from the calculation of diluted earnings per share because their effect was antidilutive. For the year ending December 31, 2000, there were no shares excluded from the calculation of diluted earnings per share. For the years ending December 31, 2001, 2000 and 1999, no adjustments were made to reported earnings in the computation of earnings per share. Common stock outstanding includes issued shares less shares held in treasury. Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted 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 construction contracts, unbilled revenues and actuarially determined benefit costs. As additional 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, 2001 2000 1999 (In thousands) Interest, net of amount capitalized $42,267 $41,912 $30,772 Income taxes $75,284 $30,930 $32,723 The company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Reclassifications Certain reclassifications have been made in the financial statements for prior years to conform to the current presentation. Such reclassifications had no effect on net income or stockholders' equity as previously reported. New accounting pronouncements In June 2001, the Financial Accounting Standards Board (FASB) approved Statement of Financial Accounting Standards No. 141, "Business Combinations" (SFAS No. 141). SFAS No. 141 requires that all business combinations be accounted for using the purchase method of accounting. The use of the pooling-of-interest method of accounting for business combinations is prohibited. The provisions of SFAS No. 141 apply to all business combinations initiated after June 30, 2001. The company is accounting for business combinations after June 30, 2001, in accordance with SFAS No. 141. In June 2001, the FASB approved SFAS No. 142. SFAS No. 142 changes the accounting for goodwill and intangible assets and requires that goodwill no longer be amortized but be tested for impairment at least annually at the reporting unit level in accordance with SFAS No. 142. Recognized intangible assets with determinable useful lives should be amortized over their useful life and reviewed for impairment in accordance with Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" (SFAS No. 144). The provisions of SFAS No. 142 are effective for fiscal years beginning after December 15, 2001, except for provisions related to the nonamortization and amortization of goodwill and intangible assets acquired after June 30, 2001, which were subject immediately to the provisions of SFAS No. 142. The company adopted SFAS No. 142 on January 1, 2002. The company ceased amortization of its recorded goodwill at June 30, 2001, on January 1, 2002. Goodwill at each reporting unit will be tested for impairment as of January 1, 2002. The company will perform this transitional goodwill impairment test within six months of the date of adoption of SFAS No. 142. However, the amounts used in the transitional goodwill impairment test shall be measured as of January 1, 2002. The company believes the adoption of the goodwill impairment provisions of SFAS No. 142 will not have a material effect on its financial position or results of operations. In June 2001, the FASB approved Statement of Financial Accounting Standards No. 143, "Accounting for Asset Retirement Obligations" (SFAS No. 143). SFAS No. 143 requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When the liability is initially recorded, the entity capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for the recorded amount or incurs a gain or loss upon settlement. SFAS No. 143 is effective for fiscal years beginning after June 15, 2002. The company will adopt SFAS No. 143 on January 1, 2003, but has not yet quantified the effects of adopting SFAS No. 143 on its financial position or results of operations. In August 2001, the FASB approved SFAS No. 144. SFAS No. 144 supersedes Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." SFAS No. 144 addresses accounting and reporting for the impairment or disposal of long-lived assets, including the disposal of a segment of a business. SFAS No. 144 is effective for fiscal years beginning after December 15, 2001. The company adopted SFAS No. 144 on January 1, 2002. The adoption of SFAS No. 144 did not have an effect on the company's financial position or results of operations. The company adopted 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) on January 1, 2001. SFAS No. 133 establishes accounting and reporting standards requiring that every derivative instrument (including certain derivative instruments embedded in other contracts) be recorded on the balance sheet as either an asset or liability measured at its fair value. SFAS No. 133 requires that changes in the derivative instrument'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. SFAS No. 133 requires that as of the date of initial adoption, the difference between the fair market value of derivative instruments recorded on the balance sheet and the previous carrying amount of those derivative instruments be reported in net income or other comprehensive income (loss), as appropriate, as the cumulative effect of a change in accounting principle in accordance with APB 20, "Accounting Changes." On January 1, 2001, the company reported a net-of-tax cumulative-effect adjustment of $6.1 million in accumulated other comprehensive loss to recognize at fair value all derivative instruments that are designated as cash-flow hedging instruments, which the company reflected in earnings over the 12 months ended December 31, 2001. The transition to SFAS No. 133 did not have an effect on the company's net income at adoption. Comprehensive income Upon the adoption of SFAS No. 133 on January 1, 2001, the company recorded a cumulative-effect adjustment in accumulated other comprehensive income to recognize all derivative instruments designated as hedges at fair value. As of December 31, 2001, the company has recorded unrealized gains and losses on swap agreements in accordance with SFAS No. 133. These amounts are reflected in the Consolidated Statements of Common Stockholders' Equity. For additional information on the adoption of SFAS No. 133, see new accounting pronouncements in Note 1, and Note 3. For the years ended December 31, 2000 and 1999, comprehensive income equaled net income as reported. 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: 2001 2000 (In thousands) Regulatory assets: Deferred income taxes $ 13,417 $ 263 Long-term debt refinancing costs 6,829 8,125 Plant costs 2,499 2,668 Postretirement benefit costs 722 833 Other 5,929 7,052 Total regulatory assets 29,396 18,941 Regulatory liabilities: Natural gas costs refundable through rate adjustments 27,706 8,772 Taxes refundable to customers 12,318 11,656 Plant decommissioning costs 8,243 7,601 Reserves for regulatory matters 7,132 6,087 Deferred income taxes 5,661 3,554 Other 5,053 1,193 Total regulatory liabilities 66,113 38,863 Net regulatory position $(36,717) $(19,922) As of December 31, 2001, 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 one to 15 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 Derivative Instruments As of December 31, 2001, the company held derivative instruments designated as cash flow hedging instruments. All derivative instruments are recognized on the Consolidated Balance Sheets at fair value. Hedging activities The cash flow hedging instruments in place at December 31, 2001, are comprised of natural gas and oil price swap agreements. The objective for holding the natural gas and oil price swap agreements is to manage a portion of the market risk associated with fluctuations in the price of natural gas and oil on the company's forecasted sales of natural gas and oil production. The company also entered into an interest rate swap agreement which expired in the fourth quarter of 2001. The objective for holding the interest rate swap agreement was to manage a portion of the company's interest rate risk on the forecasted issuance of fixed-rate debt under Centennial Energy Holdings, Inc.'s (Centennial), a direct wholly owned subsidiary of the company, commercial paper program. The company designated each of the natural gas and oil price swap agreements as a hedge of the forecasted sale of natural gas and oil production and designated the interest rate swap agreement as a hedge of the risk of changes in interest rates on the company's forecasted issuances of fixed-rate debt under Centennial's commercial paper program. The company's policy allows the use of derivative instruments as part of an overall energy price and interest rate risk management program to efficiently manage and minimize commodity price and interest rate risk. 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 hedged derivative instruments in the event of nonperformance by counterparties. The company has policies and procedures, which management believes minimize credit-risk exposure. These policies and procedures include an evaluation of potential counterparties' credit ratings, credit exposure limitations, settlement of natural gas and oil price swap agreements monthly and settlement of interest rate swap agreements within 90 days. Accordingly, the company does not anticipate any material effect to its financial position or results of operations as a result of nonperformance by counterparties. Upon the adoption of SFAS No. 133, the company recorded the fair market value of the natural gas and oil price swap agreements on the company's Consolidated Balance Sheets. On an ongoing basis, the company adjusts its balance sheet to reflect the current fair market value of its swap agreements. The related gains or losses on these agreements are recorded in common stockholders' equity as a component of other comprehensive income (loss). At the date the underlying transaction occurs, the amounts accumulated in other comprehensive income (loss) are reported in the Consolidated Statements of Income. To the extent that the hedges are not effective, the ineffective portion of the changes in fair market value is recorded directly in earnings. For the year ended December 31, 2001, the company recognized the ineffectiveness of all cash flow hedges, which is included in operating revenues and interest expense for the natural gas and oil price swap agreements and the interest rate swap agreement, respectively. For the year ended December 31, 2001, the amount of ineffectiveness recognized was immaterial. For the year ended December 31, 2001, the company did not exclude any components of the derivative instruments' gain or loss from the assessment of hedge effectiveness and there were no reclassifications into earnings as a result of the discontinuance of hedges. Gains and losses on derivative instruments that are reclassified from accumulated other comprehensive income (loss) to current-period earnings are included in the line item in which the hedged item is recorded. As of December 31, 2001, the maximum length of time over which the company is hedging its exposure to the variability in future cash flows for forecasted transactions is 12 months and the company estimates that net gains of approximately $2.2 million will be reclassified from accumulated other comprehensive income into earnings, subject to changes in natural gas and oil market prices, within the 12 months between January 1, 2002 and December 31, 2002, as the hedged transactions affect earnings. In the event a derivative instrument does not qualify for hedge accounting because it is no longer highly effective in offsetting changes in cash flows of a hedged item; or if the derivative instrument expires or is sold, terminated, or exercised; or if management determines that designation of the derivative instrument as a hedge instrument is no longer appropriate, hedge accounting will be discontinued, and the derivative instrument would continue to be carried at fair value with changes in its fair value recognized in earnings. In these circumstances, the net gain or loss at the time of discontinuance of hedge accounting would remain in other comprehensive income (loss) until the period or periods during which the hedged forecasted transaction affects earnings, at which time the net gain or loss would be reclassified into earnings. In the event a cash flow hedge is discontinued because it is unlikely that a forecasted transaction will occur, the derivative instrument would continue to be carried on the balance sheet at its fair value, and gains and losses that were accumulated in other comprehensive income (loss) would be recognized immediately in earnings. The company's policy requires approval to terminate a hedge agreement prior to its original maturity. Energy marketing The company had entered into other derivative instruments that were not designated as hedges in its energy marketing operations. In the third quarter of 2001, the company sold the vast majority of its energy marketing operations. The derivative instruments entered into by these operations prior to the sale in the third quarter of 2001 were natural gas forward purchase and sale commitments. These commitments involved the purchase and sale of natural gas and related delivery of such commodity. These operations sought to match natural gas purchases and sales so that a margin was obtained on the transportation of such commodity as distinguished from earning a margin on changes in market prices. The net change in fair value representing unrealized gains and losses resulting from changes in market prices on these derivative instruments was reflected as operating revenues or purchased natural gas sold. Net unrealized gains and losses on these derivative instruments were not material for the years ended December 31, 2001, 2000 and 1999. NOTE 4 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: 2001 2000 Carrying Fair Carrying Fair Amount Value Amount Value (In thousands) Long-term debt $794,794 $894,652 $747,761 $772,127 Preferred stock subject to mandatory redemption $ 1,400 $ 940 $ 1,500 $ 927 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 5 Short-term Borrowings The company has unsecured short-term lines of credit from a number of banks totaling $110 million at December 31, 2001. 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. There were no amounts outstanding on the short- term lines of credit at December 31, 2001. The amount outstanding on the short-term lines of credit was $8 million at December 31, 2000. The weighted average interest rate for borrowings outstanding at December 31, 2000, was 6.6 percent. NOTE 6 Long-term Debt and Indenture Provisions Long-term debt outstanding at December 31 is as follows: 2001 2000 (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 7.34%, due on dates ranging from July 31, 2002 to October 30, 2018 405,200 294,300 Commercial paper at a weighted average rate of 2.43%, supported by a revolving credit agreement 219,700 261,350 Revolving line of credit, 4.75%, due December 31, 2003 25,000 46,302 Term credit agreements at a weighted average rate of 7.38%, due on dates ranging from February 1, 2002 through December 1, 2013 11,769 12,731 Pollution control note obligation, 6.20%, due March 1, 2004 2,500 2,800 Discount (225) (572) Total long-term debt 794,794 747,761 Less current maturities 11,085 19,595 Net long-term debt $783,709 $728,166 Centennial has a revolving credit agreement with various banks that supports Centennial's $350 million commercial paper program. There were no outstanding borrowings under the Centennial credit agreement at December 31, 2001. Under the commercial paper program, $219.7 million and $261.4 million were outstanding at December 31, 2001 and 2000, 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 and as further supported by the revolving credit agreement, which allows for subsequent borrowings up to a term of one year. Centennial intends to renew this existing credit agreement, which expires September 27, 2002, on an annual basis. Centennial has an uncommitted long-term master shelf agreement that allows for borrowings of up to $300 million. Under the master shelf agreement, $210 million was outstanding at December 31, 2001, and $150 million was outstanding at December 31, 2000. The amount outstanding is included in senior notes in the preceding long-term debt table. Under a revolving line of credit, the company has $40 million available as of December 31, 2001. The amount outstanding under the revolving line of credit was $25.0 million at December 31, 2001. At December 31, 2000, the company had $46.3 million outstanding under revolving lines of credit. The amounts of scheduled long-term debt maturities for the five years and thereafter following December 31, 2001, aggregate $11.1 million in 2002; $266.8 million in 2003; $21.9 million in 2004; $70.2 million in 2005; $85.2 million in 2006 and $339.6 million thereafter. 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 $305 million of additional first mortgage bonds at December 31, 2001. Certain other debt instruments of the company contain restrictive covenants, all of which the company is in compliance with at December 31, 2001. NOTE 7 Preferred Stocks Preferred stocks at December 31 are as follows: 2001 2000 (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 -- 14,000 shares in 2001 and 15,000 shares in 2000 $ 1,400 $ 1,500 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 16,400 16,500 Less sinking fund requirements 100 100 Net preferred stocks $16,300 $16,400 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 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 is $100,000 for each of the five years following December 31, 2001, and $900,000 thereafter. NOTE 8 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. 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 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 401(k) Retirement Plan (K-Plan), is funded with the company's common stock. Since January 1, 1999, the Stock Purchase Plan and K- Plan have been funded primarily by the purchase of shares of common stock on the open market, except from January 1, 1999 through March 31, 1999, when shares of authorized but unissued common stock were used to fund the Stock Purchase Plan. At December 31, 2001, 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, and expire 10 years after the date of grant. Options granted to directors and employees vest at date of grant and three years after date of grant, respectively, and expire 10 years after the date of grant. In addition, the company has granted restricted stock awards under a long- term incentive plan, deferred compensation agreements and a restricted stock agreement totaling 350,392 shares, 348,021 shares and 105,250 shares in 2001, 2000 and 1999, respectively. The restricted stock awards granted vest to the participants at various times ranging from two 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 $31.55, $20.81 and $22.91 in 2001, 2000 and 1999, respectively. Compensation expense recognized for restricted stock grants was $4.5 million, $1.6 million and $722,000 in 2001, 2000 and 1999, respectively. Under the stock option plans and long-term incentive plan, the company is authorized to grant options and restricted stock for up to 9.8 million shares of common stock and has granted options and restricted stock on 4.8 million shares through December 31, 2001. 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 $3.8 million in 2001, $529,000 in 2000, and $498,000 in 1999. On a pro forma basis, basic and diluted earnings per share for 2001 would have been reduced by $.06. 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 would have been reduced by $.01. A summary of the status of the stock option plans at December 31, 2001, 2000 and 1999, and changes during the years then ended are as follows: 2001 2000 1999 Weighted Weighted Weighted Average Average Average Exercise Exercise Exercise Shares Price Shares Price Shares Price Balance at beginning of year 1,224,959 $20.61 1,427,262 $19.46 1,516,808 $19.17 Granted 2,693,120 30.14 74,000 20.54 22,500 23.31 Forfeited (74,282) 27.24 (84,135) 21.18 (57,966) 20.38 Exercised (371,590) 20.23 (192,168) 11.84 (54,080) 11.95 Balance at end of year 3,472,207 27.90 1,224,959 20.61 1,427,262 19.46 Exercisable at end of year 770,142 $21.41 129,763 $18.11 301,681 $13.89 Summarized information about stock options outstanding and exercisable as of December 31, 2001, is as follows: Options Outstanding Options Exercisable Remaining Weighted Weighted Contractual Average Average Range of Number Life Exercise Number Exercise Exercisable Prices Outstanding in Years Price Exercisable Price $10.50 - 17.50 41,966 3.7 $13.36 41,966 $13.36 17.51 - 24.50 789,371 6.3 21.15 698,176 21.16 24.51 - 31.50 2,490,240 9.2 29.74 --- --- 31.51 - 38.55 150,630 9.2 36.86 30,000 38.55 3,472,207 770,142 The fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model.

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 segment generates, transmits and distributes electricity and the natural gas distribution segment distributes natural gas. These operations also supply related value-added products and services in the northern Great Plains. The utility services segment consists of a diversified infrastructure company specializing in engineering, design and build capability for electric, gas and telecommunication utility construction, as well as industrial and commercial electrical, exterior lighting and traffic signalization throughout most of the United States. Utility services provides related specialty equipment manufacturing sales and rental services. The pipeline and energy services segment provides natural gas transportation, underground storage and gathering services through regulated and nonregulated pipeline systems primarily in the Rocky Mountain and northern Great Plains regions of the United States. Energy-related marketing and management services as well as cable and pipeline locating services also are provided. The pipeline and energy services segment includes investments in domestic and international growth opportunities. The natural gas and oil production segment 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 segment mines aggregates and markets crushed stone, sand, gravel and other related construction materials, including ready-mixed concrete, cement and asphalt, as well as value-added products and services in the north central and western United States, including Alaska and Hawaii. In 2001, the company sold its coal operations to Westmoreland Coal Company for $28.2 million in cash, including final settlement cost adjustments. The sale of the coal operations was effective April 30, 2001. Included in the sale were active coal mines in North Dakota and Montana, coal sales agreements, reserves and mining equipment, and certain development rights at the former Gascoyne Mine site in North Dakota. The company retains ownership of coal reserves and leases at its former Gascoyne Mine site. Including final settlement cost adjustments, the company recorded a gain of $10.3 million ($6.2 million after-tax) included in other income - net from the sale in 2001. On August 30, 2001, MDU Resources International, Inc. (MDU International), a wholly owned subsidiary of the company, through an indirect wholly owned Brazilian subsidiary, entered into a joint venture agreement with a Brazilian firm under which the parties have formed MPX Holdings, Ltda. (MPX) to develop electric generation and transmission, steam generation, power equipment, coal mining and construction materials projects in Brazil. MDU International has a 49 percent interest in MPX. MPX is currently developing, through a wholly owned subsidiary, and has under construction a 200-megawatt natural gas- fired power plant (Project) in the Brazilian state of Ceara. The Project is expected to enter commercial operation in the second quarter of 2002. MPX expects to enter into an agreement with Petrobras, the state-controlled energy company, under which Petrobras would purchase all of the capacity and market all of the Project's energy. Petrobras would also supply natural gas to the Project when energy is dispatched. The Project has a total estimated construction cost of approximately $96 million. At December 31, 2001, MDU International's investment in the Project was approximately $23.8 million. In addition, the company's subsidiaries had guaranteed Project obligations and loans for approximately $17.3 million as of December 31, 2001.

(b) Includes, in the case of electric and natural gas distribution property, allocations of common utility property. (c) 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 2001, 2000 and 1999, related to acquisitions, in the preceding table include the following noncash transactions: issuance of the company's equity securities of $57.4 million in 2001; issuance of the company's equity securities and the conversion of a note receivable to purchase consideration of $132.1 million in 2000; and issuance of the company's equity securities of $77.5 million in 1999. NOTE 11 Acquisitions In 2001, the company acquired a number of businesses, none of which was individually material, including construction materials and mining businesses in Hawaii, Minnesota and Oregon; utility services businesses based in Missouri and Oregon; and an energy services company specializing in cable and pipeline locating and tracking systems. The total purchase consideration for these businesses, consisting of the company's common stock and cash, was $170.1 million. 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 coalbed 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, Fidelity Exploration & Production Company (Fidelity), an indirect wholly owned subsidiary of the company, purchased substantially all of the assets of Preston Reynolds & Co., Inc. (Preston), a coalbed 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 certain oil and gas leases or properties acquired and/or generated by Fidelity. The Seller's Option Interest commences April 1, 2002 and terminates six months thereafter and requires Preston to pay Fidelity 25 percent of its capital investment, during the two year period subsequent to April 1, 2000, in the oil and gas leases or properties. Fidelity 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. 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 made in 2001. 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 12 Employee Benefit Plans The company has noncontributory defined benefit pension plans and other postretirement benefit plans. Changes in benefit obligation and plan assets for the years ended December 31 are as follows: Other Pension Postretirement Benefits Benefits 2001 2000 2001 2000 (In thousands) Change in benefit obligation: Benefit obligation at beginning of year $200,880 $180,997 $69,467 $65,939 Service cost 4,716 4,561 1,376 1,307 Interest cost 14,498 14,174 4,691 4,946 Plan participants' contributions --- --- 866 677 Amendments (1,342) 7,111 --- --- Actuarial (gain) loss 8,128 9,535 (2,109) 928 Divestiture* (10,017) --- (2,871) --- Benefits paid (12,817) (15,498) (4,401) (4,330) Benefit obligation at end of year 204,046 200,880 67,019 69,467 Change in plan assets: Fair value of plan assets at beginning of year 261,864 276,459 47,046 47,147 Actual return on plan assets (13,828) 875 (2,235) (1,078) Employer contribution 337 28 3,899 4,630 Plan participants' contributions --- --- 866 677 Divestiture* (10,889) --- --- --- Benefits paid (12,817) (15,498) (4,401) (4,330) Fair value of plan assets at end of year 224,667 261,864 45,175 47,046 Funded status 20,621 60,984 (21,844) (22,421) Unrecognized actuarial gain (26,170) (76,417) (10,799) (15,228) Unrecognized prior service cost 10,278 16,271 --- --- Unrecognized net transition obligation (asset) (2,195) (3,387) 23,665 28,532 Prepaid (accrued) benefit cost $ 2,534 $(2,549) $(8,978) $(9,117) * See Note 10 for more information on the sale of the company's coal operations. 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 2001 2000 2001 2000 Discount rate 7.25% 7.50% 7.25% 7.50% 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: 2001 2000 Health care trend rate 6.00%-7.00% 6.00%-7.50% 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, 2001 2000 1999 2001 2000 1999 (In thousands) Components of net periodic benefit cost: Service cost $ 4,716 $ 4,561 $ 4,894 $ 1,376 $ 1,307 $1,451 Interest cost 14,498 14,174 12,573 4,691 4,946 4,720 Expected return on assets (20,672) (19,927) (17,489) (3,619) (3,267) (2,807) Amortization of prior service cost 1,247 1,047 842 --- --- --- Recognized net actuarial gain (2,687) (2,907) (995) (930) (799) (200) Settlement (gain) loss (884) (700) --- 15 --- --- Amortization of net transition obligation (asset) (965) (997) (997) 2,227 2,378 2,377 Net periodic benefit cost (income) (4,747) (4,749) (1,172) 3,760 4,565 5,541 Less amount capitalized (391) (397) (87) 329 369 463 Net periodic benefit expense (income) $(4,356) $(4,352) $(1,085) $ 3,431 $ 4,196 $5,078 The company's other postretirement benefit plans include health care and life insurance benefits. 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 plans 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, 2001: 1 Percentage 1 Percentage Point Increase Point Decrease (In thousands) Effect on total of service and interest cost components $ 260 $ (229) Effect on postretirement benefit obligation $ 3,326 $(2,906) In addition to company-sponsored plans, certain employees are covered under multi-employer defined benefit plans administered by a union. Amounts contributed to the multi-employer plans were $19.9 million, $10.6 million and $6.8 million in 2001, 2000 and 1999, 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 $4.3 million, $3.5 million and $3.3 million in 2001, 2000 and 1999, respectively. The company sponsors various defined contribution plans for eligible employees. Costs incurred by the company under these plans were $7.2 million in 2001, $6.1 million in 2000 and $4.4 million in 1999. The costs incurred in each year reflect additional participants as a result of business acquisitions. NOTE 13 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: 2001 2000 (In thousands) Big Stone Station: Utility plant in service $ 50,053 $ 50,029 Less accumulated depreciation 32,956 31,381 $ 17,097 $ 18,648 Coyote Station: Utility plant in service $122,436 $122,111 Less accumulated depreciation 67,414 63,741 $ 55,022 $ 58,370 NOTE 14 Regulatory Matters and Revenues Subject To Refund In December 1999, Williston Basin Interstate Pipeline Company (Williston Basin), an indirect wholly owned subsidiary of the company, filed a general natural gas rate change application with the FERC. Williston Basin began collecting such rates effective June 1, 2000, subject to refund. On May 9, 2001, the Administrative Law Judge issued an Initial Decision on Williston Basin's natural gas rate change application, which matter is currently pending before and subject to revision by the FERC. Reserves have been provided for a portion of the revenues that have been collected subject to refund with respect to the pending regulatory proceeding. Williston Basin, in the fourth quarter of 2000, determined that reserves it had previously established for certain regulatory proceedings, prior to the proceeding filed in 1999, 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 15 Commitments and Contingencies Litigation In March 1997, 11 natural gas producers filed suit in North Dakota Southwest 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 Northwest Judicial District Court in December 1993. The North Dakota Supreme Court in December 1999 affirmed the North Dakota Northwest Judicial 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 in July 2000. On March 5, 2001, the North Dakota District Court entered a final judgment on the July 2000 order granting the motions for summary judgment. On May 4, 2001, the 11 natural gas producers appealed the North Dakota District Court's decision by filing a Notice of Appeal with the North Dakota Supreme Court. Oral argument was held before the North Dakota Supreme Court on December 12, 2001. Williston Basin and the company are awaiting a decision from the North Dakota Supreme Court. 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 United States Court of Appeals for the D.C. Circuit in October 1998. In June 1997, Grynberg filed a similar Federal False Claims Act suit against Williston Basin and Montana- Dakota Utilities Co. (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 in March 2000. On May 18, 2001, the Federal District Court denied Williston Basin's and Montana-Dakota's motion to dismiss. The matter is currently pending. 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, (State District Court) 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. Upon motion of plaintiffs, the case has been remanded to State District Court. On September 12, 2001, the defendants in this suit filed a motion to dismiss with the State District Court. The matter is currently pending. 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. Operating leases The company leases certain equipment, facilities and land under operating lease agreements. The amounts of annual minimum lease payments due under these leases as of December 31, 2001, are $17.4 million in 2002, $14.3 million in 2003, $11.0 million in 2004, $8.3 million in 2005, $6.3 million in 2006 and $25.1 million thereafter. Rent expense related to operating leases was approximately $31.5 million, $23.7 million and $15.4 million for the years ended December 31, 2001, 2000 and 1999, respectively. Purchase commitments The company has entered into various commitments, largely purchased- power, coal and natural gas supply, and natural gas transportation contracts. These commitments range from one to 17 years. The commitments under these contracts as of December 31, 2001, are $108.8 million in 2002, $53.1 million in 2003, $46.9 million in 2004, $39.2 million in 2005, $33.2 million in 2006 and $126.5 million thereafter. These commitments are not reflected in the company's consolidated financial statements. Guarantees The company has certain financial guarantees largely consisting of guarantees on obligations and loans on the natural gas-fired power plant project in the Brazilian state of Ceara. For more information on the natural gas-fired power plant project see Note 10. These guarantees, as of December 31, 2001, are approximately $20.6 million for 2002. These guarantees are not reflected in the consolidated financial statements. NOTE 16 Quarterly Data (Unaudited) The following unaudited information shows selected items by quarter for the years 2001 and 2000: First Second Third Fourth Quarter Quarter Quarter Quarter (In thousands, except per share amounts) 2001 Operating revenues $641,248 $546,418 $551,680 $484,286 Operating expenses 577,727 476,071 458,441 438,125 Operating income 63,521 70,347 93,239 46,161 Net income 32,687 43,417 50,746 28,999 Earnings per common share: Basic .50 .64 .75 .42 Diluted .49 .63 .74 .42 Weighted average common shares outstanding: Basic 65,405 67,264 67,650 68,729 Diluted 65,979 68,376 68,127 69,126 2000 Operating revenues $371,989 $362,979 $530,834 $607,869 Operating expenses 342,559 321,900 454,811 537,414 Operating income 29,430 41,079 76,023 70,455 Net income 13,364 21,126 39,992 36,546 Earnings per common share: Basic .23 .35 .63 .57 Diluted .23 .35 .63 .56 Weighted average common shares outstanding: Basic 57,051 59,987 62,975 64,289 Diluted 57,188 60,212 63,345 64,817 Certain company operations are highly seasonal and revenues from and certain expenses for such operations may fluctuate significantly among quarterly periods. Accordingly, quarterly financial information may not be indicative of results for a full year. NOTE 17 Natural Gas and Oil Activities (Unaudited) Fidelity is involved in the acquisition, exploration, development and production of natural gas and oil resources. Fidelity's activities include the acquisition of producing properties with potential development opportunities, exploratory drilling and the operation and development 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, North Dakota and Wyoming.

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. 2001 2000 1999 Natural Natural Natural Gas Oil Gas Oil Gas Oil (In thousands of Mcf/barrels) Proved developed and undeveloped reserves: Balance at beginning of year 309,800 15,100 268,900 14,700 243,600 11,500 Production (40,600) (2,000)(29,200) (1,900)(24,700) (1,800) Extensions and discoveries 66,400 2,000 51,300 1,600 21,800 800 Purchases of proved reserves 1,000 100 23,200 100 38,200 700 Sales of reserves in place --- --- --- (100) (9,300) (400) Revisions to previous estimates due to improved secondary recovery techniques and/or changed economic conditions (12,500) 2,300 (4,400) 700 (700) 3,900 Balance at end of year 324,100 17,500 309,800 15,100 268,900 14,700 Proved developed reserves: January 1, 1999 193,000 10,700 December 31, 1999 213,400 13,300 December 31, 2000 263,400 14,200 December 31, 2001 291,300 17,100 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: 2001 2000 1999 (In thousands) Future net cash flows before income taxes $548,000 $2,349,500 $492,000 Future income tax expense 112,000 827,000 131,500 Future net cash flows 436,000 1,522,500 360,500 10% annual discount for estimated timing of cash flows 174,000 601,200 131,400 Discounted future net cash flows relating to proved natural gas and oil reserves $262,000 $ 921,300 $229,100 The following are the sources of change in the standardized measure of discounted future net cash flows by year: 2001 2000 1999 (In thousands) Beginning of year $ 921,300 $229,100 $125,100 Net revenues from production (153,500) (94,300) (49,900) Change in net realization (1,119,700) 861,700 123,100 Extensions, discoveries and improved recovery, net of future production-related costs 64,200 288,700 33,500 Purchases of proved reserves 2,600 93,200 57,700 Sales of reserves in place --- (1,500) (14,700) Changes in estimated future development costs, net of those incurred during the year (3,300) 3,400 (9,800) Accretion of discount 126,900 31,200 16,700 Net change in income taxes 436,500 (412,300) (59,800) Revisions of previous quantity estimates (11,700) (79,200) 7,400 Other (1,300) 1,300 (200) Net change (659,300) 692,200 104,000 End of year $ 262,000 $921,300 $229,100 The estimated discounted future cash inflows from estimated future production of proved reserves were computed using year-end natural gas prices and oil prices. 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. NOTE 18 Subsequent Event In January 2002, Fidelity Oil Co. (FOC), one of the company's natural gas and oil production subsidiaries, entered into a compromise agreement with the former operator of certain of FOC's oil production properties in southeastern Montana. The compromise agreement resolved litigation involving the interpretation and application of contractual provisions regarding net proceeds interests paid by the former operator to FOC for a number of years prior to 1998. The terms of the compromise agreement are confidential. As a result of the compromise agreement, the natural gas and oil production segment will reflect a nonrecurring gain in its financial results for the first quarter of 2002 of approximately $16.6 million after-tax. As part of the settlement, FOC gave the former operator a full and complete release, and FOC is not asserting any such claim against the former operator for periods after 1997. 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, 2001 and 2000, 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, 2001. 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, 2001 and 2000, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2001, in conformity with accounting principles generally accepted in the United States. As explained in Note 1 to the consolidated financial statements, effective January 1, 2001, the company changed its method of accounting for derivative instruments due to the adoption of a new accounting pronouncement. /s/ ARTHUR ANDERSEN LLP ARTHUR ANDERSEN LLP Minneapolis, Minnesota January 23, 2002 OPERATING STATISTICS MDU RESOURCES GROUP, INC. 2001 2000 1999 1998* 1997 1996 1991

the Audit Committee of the Board of Directors, the Board of Directors of the company approved the dismissal of Arthur Andersen LLP (Arthur Andersen) as the company's independent auditors following the 2001 audit. The company has not selected independent auditors for the 2002 fiscal year, but is currently in the process of reviewing new auditor candidates and expects to make a selection in the near future. In connection with the audits for the two most recent fiscal years and through February 20, 2002, there have been no disagreements with Arthur Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Arthur Andersen, would have caused Arthur Andersen to make reference thereto in its report on the financial statements of the company for such time periods. Also, during those time periods, there have been no "reportable events," as such term is used in Item 304 (a)(1)(v) of Regulation S-K. Arthur Andersen's reports on the financial statements of the company for the last two years neither contained an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. We have provided Arthur Andersen a copy of the company's Form 8-K prior to its filing with the Securities and Exchange Commission (Commission). Arthur Andersen has provided us with a letter, addressed to the Commission, which is filed as an Exhibit to the company's Form 8-K, as filed with the Commission on February 20, 2002. To MDU Resources Group, Inc.: We have audited in accordance with auditing standards generally accepted in the United States, the financial statements included in MDU Resources Group, Inc.'s annual report to stockholders incorporated by reference in this Form 10-K, and have issued our report thereon dated January 23, 2002. Our audit was made for the purpose of forming an opinion on those statements taken as a whole. Schedule II is the responsibility of the company's management and is presented for purposes of complying with the Securities and Exchange Commission's rules and is not part of the basic financial statements. This schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, fairly states in all material respects the financial data required to be set forth therein in relation to the basic financial statements taken as a whole. /s/ ARTHUR ANDERSEN LLP ARTHUR ANDERSEN LLP Minneapolis, Minnesota, January 23, 2002 MDU RESOURCES GROUP, INC.
