1996 FINANCIAL REPORT REPORT OF MANAGEMENT The management of MDU Resource 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 non-regulated 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, careful selection and training of personnel, written policies and procedures and periodic reviews by the Internal Audit 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 Audit 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 generally accepted auditing standards 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.

NOTE 1 Statement of Principal Accounting Policies Basis of Presentation The consolidated financial statements of MDU Resources Group, Inc. (the "company") include the accounts of two regulated businesses -- retail and wholesale sales of electricity and retail sales and/or transportation of natural gas and propane, and natural gas transmission and storage -- and two non-regulated businesses -- construction materials and mining operations, and oil and natural gas production. The statements also include the ownership interests in the assets, liabilities and expenses of two jointly owned electric generating 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 non-regulated 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 allows 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 6 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. 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 oil and natural gas 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 amounts of AFUDC and interest capitalized were not material in 1996, 1995 and 1994. Property, plant and equipment are depreciated on a straight-line basis over the average useful lives of the assets, except for oil and natural gas production properties as described below. Investments Investments consist principally of the company's partnership investment in Hawaiian Cement. The company accounts for its partnership investment in Hawaiian Cement by the equity method. See Note 16 for more information on this partnership investment. Oil and Natural Gas The company uses the full-cost method of accounting for its oil and natural gas production activities. Under this method, all costs incurred in the acquisition, exploration and development of oil and natural gas properties are capitalized and amortized on the units of production method based on total proved reserves. Cost centers for amortization purposes are determined on a country-by-country basis. 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. 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 realized. Natural Gas in Underground Storage and Available Under Repurchase Commitment Natural gas in underground storage is carried at cost using the last-in, first-out (LIFO) method. That portion of the cost of natural gas in underground storage expected to be used within one year is included in inventories. Natural gas available under a repurchase commitment with Frontier Gas Storage Company (Frontier) is carried at Frontier's cost of purchased natural gas, less an allowance to reflect changed market conditions. See Note 3 for more information on a write-down of the natural gas available under the repurchase commitment with Frontier which occurred in 1996. Inventories Inventories, other than natural gas in underground storage, consist primarily of materials and supplies and inventory held for resale. 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. In addition, the company recognizes revenue for its construction business on the percentage of completion method. 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 24 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 Montana-Dakota's and Williston Basin'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 deferred credits" in the company's Consolidated Balance Sheets. This regulatory liability is 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. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles 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 plant depreciable lives, tax provisions, uncollectible accounts, environmental and other loss contingencies, 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, 1996 1995 1994 (In thousands) Interest, net of amount capitalized $25,449 $24,436 $22,775 Income taxes $28,163 $18,330 $13,539 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 1995 and 1994 to conform to the 1996 presentation. Such reclassifications had no effect on net income or common stockholders' investment as previously reported. New Accounting Standard In October 1996, the American Institute of Certified Public Accountants issued Statement of Position 96-1, "Environmental Remediation Liabilities" (SOP 96-1). SOP 96-1 provides authoritative guidance for the recognition, measurement, display and disclosure of environmental remediation liabilities in financial statements. The company will adopt SOP 96-1 on January 1, 1997, and the adoption is not expected to have a material effect on the company's financial position or results of operations. NOTE 2 Regulatory Matters and Revenues Subject to Refund General Rate Proceedings Williston Basin has pending with the FERC a general natural gas rate change application implemented in 1992. In July 1995, the FERC issued an order relating to Williston Basin's rate change application. In August 1995, Williston Basin filed, under protest, tariff sheets in compliance with the FERC's order, with rates which went into effect on September 1, 1995. Williston Basin requested rehearing of certain issues addressed in the order. On July 19, 1996, the FERC issued an order granting in part and denying in part Williston Basin's rehearing request. A hearing was held on August 29, 1996, and this matter is currently pending before the FERC. In addition, Williston Basin has appealed certain issues contained in the FERC's orders to the U.S. Court of Appeals for the D.C. Circuit (D.C. Circuit Court). Williston Basin anticipates filing briefs with the D.C. Circuit Court on February 3, 1997, related to its appeal of orders which had been received from the FERC beginning in May 1993, regarding the appropriate selling price of certain natural gas in underground storage which was determined to be excess upon Williston Basin's implementation of Order 636. The FERC ordered that the gas be offered for sale to Williston Basin's customers at its original cost. Williston Basin requested rehearing of this matter on the grounds that the FERC's order constituted a confiscation of its assets, which request was subsequently denied by the FERC. Williston Basin believes that it should be allowed to sell this natural gas at its fair value and retain any profits resulting from such sales since its ratepayers had never paid for the natural gas. Oral arguments on this matter before the D.C. Circuit Court are scheduled for May 9, 1997. Reserves have been provided for a portion of the revenues that have been collected subject to refund with respect to pending regulatory proceedings and for the recovery of certain producer settlement buy- out/buy-down costs to reflect future resolution of certain issues with the FERC. Williston Basin believes that such reserves are adequate based on its assessment of the ultimate outcome of the various proceedings. NOTE 3 Natural Gas Repurchase Commitment The company has offered for sale since 1984 the inventoried natural gas owned by Frontier, a special purpose, non-affiliated corporation. Through an agreement, Williston Basin is obligated to repurchase all of the natural gas at Frontier's original cost and reimburse Frontier for all of its financing and general administrative costs. Frontier has financed the purchase of the natural gas under a term loan agreement with several banks. At December 31, 1996, borrowings totalled $84.0 million at a weighted average interest rate of 6.13 percent of which $66.3 million is reflected on the company's Consolidated Balance Sheets under "Natural gas repurchase commitment" and $17.7 million is included in "Other accrued liabilities" and relates to current amounts owed as a result of recent sales of a portion of this natural gas. The term loan agreement will terminate on October 2, 1999, subject to an option to renew this agreement upon the lenders' consent for up to five years, unless terminated earlier by the occurrence of certain events. The FERC has issued orders that have held that storage costs should be allocated to this gas, prospectively beginning May 1992, as opposed to being included in rates applicable to Williston Basin's customers. These storage costs, as initially allocated to the Frontier gas, approximated $2.1 million annually, for which Williston Basin has provided reserves. Williston Basin appealed these orders to the D.C. Circuit Court. On December 26, 1996, the D.C. Circuit Court issued its order ruling that the FERC's actions in allocating costs to the Frontier gas were appropriate. Williston Basin is awaiting a final order from the FERC. Beginning in October 1992, as a result of prevailing natural gas prices, Williston Basin began to sell and transport a portion of the natural gas held under the repurchase commitment. Through the second quarter of 1996, 17.8 MMdk of this natural gas had been sold. However, in the third quarter of 1996, Williston Basin, based on a number of factors including differences in regional natural gas prices and natural gas sales occurring at that time, wrote down the remaining 43.0 MMdk of this gas to its then current market value. The value of this gas was determined using the sum of discounted cash flows of expected future sales occurring at then current regional natural gas prices as adjusted for anticipated future price increases. This resulted in a write-down aggregating $18.6 million ($11.4 million after tax). In addition, Williston Basin wrote off certain other costs related to this natural gas of approximately $2.5 million ($1.5 million after tax). The amounts related to this write-down are included in "Costs on natural gas repurchase commitment" in the Consolidated Statements of Income. The recognition of the then current market value of this natural gas facilitated the sale by Williston Basin of 10.5 MMdk from the date of this write-down through December 31, 1996, and should allow Williston Basin to market the remaining 32.5 MMdk on a sustained basis enabling Williston Basin to liquidate this asset over approximately the next five years. NOTE 4 Commitments and Contingencies Pending Litigation In November 1993, the estate of W.A. Moncrief (Moncrief), a producer from whom Williston Basin purchased a portion of its natural gas supply, filed suit in Federal District Court for the District of Wyoming (Federal District Court) against Williston Basin and the company disputing certain price and volume issues under the contract. Through the course of this action Moncrief submitted damage calculations which totalled approximately $19 million or, under its alternative pricing theory, approximately $39 million. On August 16, 1996, the Federal District Court issued its decision finding that Moncrief is entitled to damages for the difference between the price Moncrief would have received under the geographic favored-nations price clause of the contract for the period from August 13, 1993, through July 7, 1996, and the actual price received for the gas. The favored-nations price is the highest price paid from time to time under contracts in the same geographic region for natural gas of similar quantity and quality. The Federal District Court reopened the record until October 15, 1996, to receive additional briefs and exhibits on this issue. On October 15, 1996, Moncrief submitted its brief claiming damages ranging as high as $22 million under the geographic favored-nations price theory. Williston Basin, in its brief, contended that Moncrief waived its claim for a favored-nations price under an agreement with Williston Basin, and Moncrief's damage claims were calculated utilizing non-comparable contracts. Williston Basin's exhibits show Moncrief's damages should be limited to approximately $800,000 under the geographic favored-nations price theory. A hearing on all pending matters is currently scheduled for April 3, 1997. Williston Basin plans to file for recovery from ratepayers of amounts which may be ultimately due to Moncrief, if any. In December 1993, Apache Corporation (Apache) and Snyder Oil Corporation (Snyder) filed suit in North Dakota District Court, Northwest Judicial District, against Williston Basin and the company. Apache and Snyder are oil and natural gas producers who had processing agreements with Koch Hydrocarbon Company (Koch). Williston Basin and the company had a natural gas purchase contract with Koch. Apache and Snyder have alleged they are entitled to damages for the breach of Williston Basin's and the company's contract with Koch. Williston Basin and the company believe that if Apache and Snyder have any legal claims, such claims are with Koch, not with Williston Basin or the company. Williston Basin, the company and Koch have settled their disputes. Apache and Snyder have recently provided alleged damages under differing theories ranging up to $8.2 million without interest. A motion to intervene in the case by several other producers, all of whom had contracts with Koch but not with Williston Basin, was denied on December 13, 1996. Trial on this matter is scheduled for September 8, 1997. The claims of Apache and Snyder, in Williston Basin's opinion, are without merit and overstated. If any amounts are ultimately found to be due Apache and Snyder, Williston Basin plans to file for recovery from ratepayers. On July 18, 1996, Jack J. Grynberg (Grynberg) filed suit in United States District Court for the District of Columbia against Williston Basin and over 70 other natural gas pipeline companies. Grynberg, acting on behalf of the United States under the False Claims Act, is alleging 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. The United States government, particularly officials from the Departments of Justice and Interior, reviewed the complaint and the evidence presented by Grynberg and declined to intervene in the action, permitting Grynberg to proceed on his own. Williston Basin believes Grynberg's claims are without merit and intends to vigorously contest this suit. In November 1995, a suit was filed in District Court, County of Burleigh, State of North Dakota (State District Court) by Minnkota Power Cooperative, Inc., Otter Tail Power Company, Northwestern Public Service Company and Northern Municipal Power Agency (Co-owners), the owners of an aggregate 75 percent interest in the Coyote electrical generating station (Coyote Station), against the company (an owner of a 25 percent interest in the Coyote Station) and Knife River. In its complaint, the Co-owners alleged a breach of contract against Knife River of the long-term coal supply agreement (Agreement) between the owners of the Coyote Station and Knife River. The Co-owners have requested a determination by the State District Court of the pricing mechanism to be applied to the Agreement and have further requested damages during the term of such alleged breach on the difference between the prices charged by Knife River and the prices as may ultimately be determined by the State District Court. The Co-owners also alleged a breach of fiduciary duties by the company as operating agent of the Coyote Station, asserting essentially that the company was unable to cause Knife River to reduce its coal price sufficiently under the Agreement, and are seeking damages in an unspecified amount. On January 8, 1996, the company and Knife River filed separate motions with the State District Court to dismiss or stay pending arbitration. On May 6, 1996, the State District Court granted the company's and Knife River's motions and stayed the suit filed by the Co-owners pending arbitration, as provided for in the Agreement. On September 12, 1996, the Co-owners notified the company and Knife River of their demand for arbitration of the pricing dispute that had arisen under the Agreement. The demand for arbitration, filed with the American Arbitration Association (AAA), did not make any direct claim against the company in its capacity as operator of the Coyote Station. The Co-owners requested that the arbitrators make a determination that the pricing dispute is not a proper subject for arbitration. In the alternative, the Co-owners requested the arbitrators to make a determination that the prices charged by Knife River were excessive and that the Co-owners should be awarded damages based upon the difference between the prices that Knife River charged and a "fair and equitable" price, approximately $50 million or more. Upon application by the company and Knife River, the AAA administratively determined that the company was not a proper party defendant to the arbitration, and the arbitration is proceeding against Knife River. Although unable to predict the outcome of the arbitration, Knife River and the company believe that the Co-owners claims are without merit and intend to vigorously defend the prices charged pursuant to the Agreement. For a description of litigation filed by Unitek Environmental Services, Inc. against Hawaiian Cement, see Environmental Matters. 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 Montana-Dakota and Williston Basin discovered polychlorinated biphenyls (PCBs) in portions of their natural gas systems and informed the United States Environmental Protection Agency (EPA) in January 1991. Montana-Dakota and Williston Basin believe the PCBs entered the system from a valve sealant. In January 1994, Montana- Dakota, Williston Basin and Rockwell International Corporation (Rockwell), manufacturer of the valve sealant, reached an agreement under which Rockwell has and will continue to reimburse Montana-Dakota and Williston Basin for a portion of certain remediation costs. On the basis of findings to date, Montana-Dakota and Williston Basin estimate future environmental assessment and remediation costs will aggregate $3 million to $15 million. Based on such estimated cost, the expected recovery from Rockwell and the ability of Montana-Dakota and Williston Basin to recover their portions of such costs from ratepayers, Montana-Dakota and Williston Basin believe that the ultimate costs related to these matters will not be material to each of their respective financial positions or results of operations. In September 1995, Unitek Environmental Services, Inc. and Unitek Solvent Services, Inc. (Unitek) filed a complaint against Hawaiian Cement in the United States District Court for the District of Hawaii (District Court) alleging that dust emissions from Hawaiian Cement's cement manufacturing plant at Kapolei, Hawaii (Plant) violated the Hawaii State Implementation Plan (SIP) of the U.S. Clean Air Act (Clean Air Act), constituted a continual nuisance and trespass on the plaintiff's property, and that Hawaiian Cement's conduct warranted the payment of punitive damages. Hawaiian Cement is a Hawaiian general partnership whose general partners (with joint and several liability) are Knife River Hawaii, Inc., an indirect wholly owned subsidiary of the company, and Adelaide Brighton Cement (Hawaii), Inc. Unitek is seeking civil penalties under the Clean Air Act (as described below), and had sought damages for various claims (as described above) of up to $20 million in the aggregate. On August 7, 1996, the District Court issued an order granting Plaintiffs' motion for partial summary judgment relating to the Clean Air Act, indicating that it would issue an injunction shortly. The issue of civil penalties under the Clean Air Act was reserved for further hearing at a later date, and Unitek's claims for damages were not addressed by the District Court at such time. On September 16, 1996, Unitek and Hawaiian Cement reached a settlement which resolved all claims relating to the $20 million in damages that Unitek had previously sought. However, the settlement did not resolve the matter regarding the civil penalties sought by Unitek relating to the alleged violations by Hawaiian Cement of the Clean Air Act nor did it affect the EPA's Notice of Violation (NOV) as discussed below. Based on a joint petition filed by Unitek and Hawaiian Cement, the District Court stayed the proceeding and the issuance of an injunction while the parties continue to negotiate the remaining Clean Air Act claims. On May 7, 1996, the EPA issued a NOV to Hawaiian Cement. The NOV states that dust emissions from the Plant violated the SIP. Under the Clean Air Act, the EPA has the authority to issue an order requiring compliance with the SIP, issue an administrative order requiring the payment of penalties of up to $25,000 per day per violation (not to exceed $200,000), or bring a civil action for penalties of not more than $25,000 per day per violation and/or bring a civil action for injunctive relief. It is also possible that the EPA could elect to join the suit filed by Unitek. Depending upon the specific actions that may ultimately be taken by either the EPA or the District Court, Hawaiian Cement is likely to have to modify its operations at its cement manufacturing facility. Hawaiian Cement has met with the EPA and settlement discussions are currently ongoing. Although no assurance can be provided, the company does not believe that the total cost of any modifications to the facility, the level of civil penalties which may ultimately be assessed or settlement costs, will have a material effect on the company's results of operations. Electric Purchased Power Commitments Montana-Dakota has contracted to purchase through October 31, 2006, up to 66,400 kW of participation power 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 from Black Hills Power and Light Company. NOTE 5 Natural Gas in Underground Storage Natural gas in underground storage included in natural gas transmission and natural gas distribution property, plant and equipment amounted to approximately $42.3 million at December 31, 1996, $42.1 million at December 31, 1995, and $45.2 million at December 31, 1994. In addition, $7.2 million, $6.6 million and $6.9 million at December 31, 1996, 1995 and 1994, respectively, of natural gas in underground storage is included in inventories. NOTE 6 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: 1996 1995 1994 (In thousands) Regulatory assets: Natural gas contract settlement and restructuring costs $ 4,960 $ 15,275 $ 24,069 Long-term debt refinancing costs 13,520 11,082 12,228 Postretirement benefit costs 3,849 4,833 4,551 Plant costs 3,341 3,509 3,678 Other 7,890 7,091 4,664 Total regulatory assets 33,560 41,790 49,190 Regulatory liabilities: Reserves for regulatory matters 59,277 58,277 49,427 Natural gas costs refundable through rate adjustments 1,499 21,192 14,878 Taxes refundable to customers 12,868 12,531 12,229 Plant decommissioning costs 5,301 4,777 4,290 Other 2,433 7,205 9,883 Total regulatory liabilities 81,378 103,982 90,707 Net regulatory position $(47,818) $(62,192) $(41,517) As of December 31, 1996, substantially all of the company's regulatory assets are being reflected in rates charged to customers and are being recovered over the next 1 to 20 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 7 Financial Instruments Derivatives The company, in connection with the operations of Montana-Dakota, Williston Basin and Fidelity Oil, has entered into certain price swap and collar agreements (hedge agreements) to manage a portion of the market risk associated with fluctuations in the price of oil and natural gas. These hedge agreements are not held for trading purposes. The hedge 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 hedge agreements. The variable price is either an oil price quoted on the New York Mercantile Exchange (NYMEX) or a quoted natural gas price on the NYMEX or Colorado Interstate Gas Index. The company believes that there is a high degree of correlation because the timing of purchases and production and the hedge agreements are closely matched, and hedge prices are established in the areas of the company's operations. Amounts payable or receivable on hedge agreements are 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 amounts payable or receivable are offset by corresponding increases and decreases in the value of the underlying commodity transactions. Williston Basin and Knife River have entered into interest rate swap agreements to manage a portion of their interest rate exposure on a natural gas repurchase commitment and long-term debt, respectively. These interest rate swap agreements are not held for trading purposes. The interest rate swap agreements call for the company to receive quarterly payments from or make payments to counterparties based upon the difference between fixed and variable rates as specified by the interest rate swap agreements. The variable prices are based on the three-month floating London Interbank Offered Rate. Settlement amounts payable or receivable under these interest rate swap agreements are recorded in "Interest expense" for Knife River and "Costs on natural gas repurchase commitment" for Williston Basin on the Consolidated Statements of Income in the accounting period they are incurred. The amounts payable or receivable are offset by interest on the related debt instruments. The company's policy prohibits the use of derivative instruments for trading purposes and the company has procedures in place to monitor their use. The company is exposed to credit-related losses in the event of nonperformance by counterparties to these financial instruments, but does not expect any counterparties to fail to meet their obligations given their existing credit ratings. The following table summarizes the company's hedging activity for 1996, 1995 and 1994: 1996 1995 1994 (Notional amounts in thousands) Oil swap/collar agreements:* Range of fixed prices per barrel $18.74-$19.07 $17.75-$20.75 $17.00-$21.05 Notional amount (in barrels) 635 260 242 Natural gas swap/collar agreements:* Range of fixed prices per MMBtu $1.40-$2.05 $1.70-$1.85 $1.85-$2.32 Notional amount (in MMBtu's) 5,331 644 3,130 Natural gas collar agreement:** Fixed price per MMBtu $1.22-$1.52 $1.22-$1.52 --- Notional amount (in MMBtu's) 910 2,750 --- Interest rate swap agreements:** Range of fixed interest rates 5.50%-6.50% 5.97% --- Notional amount (in dollars) $30,000 $20,000 --- * Receive fixed -- pay variable ** Receive variable -- pay fixed The following table summarizes swap agreements outstanding at December 31, 1996 (notional amounts in thousands): Range of Notional Fixed Prices Amount Year (Per barrel) (In barrels) Oil swap agreements* 1997 $19.77-$21.36 730 Range of Notional Fixed Prices Amount Year (Per MMBtu) (In MMBtu's) Natural gas swap agreements* 1997 $1.30-$2.25 7,737 Notional Range of Fixed Amount Year Interest Rates (In dollars) Interest rate swap agreements:** 1997 5.50%-6.50% $30,000 1998 5.50%-6.50% $10,000 * Receive fixed -- pay variable ** Receive variable -- pay fixed 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 currently not recorded on the company's financial statements. Favorable and unfavorable positions related to oil and natural gas hedge agreements will be offset by corresponding increases and decreases in the value of the underlying commodity transactions. Favorable and unfavorable positions on interest rate swap agreements will be offset by interest on the related debt instruments. The company's net unfavorable position on all swap and collar agreements outstanding at December 31, 1996, was $4.2 million. Fair Value of Other Financial Instruments The estimated fair value of the company's long-term debt and preferred stocks are based on quoted market prices of the same or similar issues. The estimated fair value of the company's long-term debt and preferred stocks at December 31 are as follows: 1996 1995 1994 Carrying Fair Carrying Fair Carrying Fair Amount Value Amount Value Amount Value (In thousands) Long-term debt $292,420 $298,592 $254,339 $ 274,320 $ 238,043 $ 233,196 Preferred stocks $ 16,900 $ 10,762 $ 17,000 $ 10,500 $ 17,100 $ 10,486 The fair value of other financial instruments for which estimated fair values have not been presented is not materially different than the related book value. NOTE 8 Short-term Borrowings The company and its subsidiaries had unsecured lines of credit from several banks totalling $91.4 million at December 31, 1996. 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 under the lines of credit were $4.0 million at December 31, 1996, $600,000 at December 31, 1995, and $680,000 at December 31, 1994. The weighted average interest rate for borrowings outstanding at December 31, 1996, 1995 and 1994, was 7.25 percent, 8.50 percent and 8.50 percent, respectively. The unused portions of the lines of credit are subject to withdrawal based on the occurrence of certain events. NOTE 9 Common Stock At the Annual Meeting of Stockholders held in April 1994, the company's common stockholders approved an amendment to the Certificate of Incorporation increasing the authorized number of common shares from 50 million shares to 75 million shares and reducing the par value of the common stock from $5.00 per share to $3.33 per share. In August 1995, the company's Board of Directors approved a three-for- two common stock split to be effected in the form of a 50 percent common stock dividend. The additional shares of common stock were distributed on October 13, 1995, to common stockholders of record on September 27, 1995. Common stock information appearing in the accompanying consolidated financial statements and notes thereto has been restated to give retroactive effect to the stock split, except for shares outstanding in 1994 as set forth in the table below. Changes in common stock and other paid in capital during the years ended December 31, 1996, 1995 and 1994 are summarized below: Shares Par Other Paid Outstanding Value In Capital (In thousands) Balance at December 31, 1994 18,984,654 $63,219 $ 95,914 Three-for-two common stock split 9,492,327 31,609 (31,609) Balance at December 31, 1995 and 1996 28,476,981 $94,828 $ 64,305 The company's Automatic Dividend Reinvestment and Stock Purchase Plan (DRIP) provides participants in the DRIP the opportunity to invest all or a portion of their cash dividends in shares of the company's common stock and/or 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 and other investors who are domiciled in the states of North Dakota, South Dakota, Montana or Wyoming, are eligible to participate in the DRIP. The company's Tax Deferred Compensation Savings Plans (K-Plans) pursuant to Section 401(k) of the Internal Revenue Code are funded with the company's common stock. Shares held in the K-Plans also participate in the DRIP. Since January 1, 1989, the DRIP and K- Plans have been funded by the purchase of shares of common stock on the open market. However, beginning January 1, 1997, shares of authorized but unissued common stock are being used to fund the DRIP. At December 31, 1996, there were 5,830,345 shares of common stock reserved for issuance under the DRIP and K-Plans. In November 1988, the company's Board of Directors declared, pursuant to a stockholders' rights plan, a dividend of one preference share purchase right (right) on each outstanding share of the company's common stock. Each right becomes exercisable, upon the occurrence of certain events, for one one-hundred and fiftieth of a share of Series A preference stock, without par value, at an exercise price of $33.33 per one one-hundred and fiftieth, 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 20 percent or more of the company's common stock or commences a tender or exchange offer that would result in ownership of 30 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-hundredths of a Series A preference share 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 in November 1998, are redeemable in whole, but not in part, for a price of $.01333 per right, at the company's option at any time until any acquiring person has acquired 20 percent or more of the company's common stock. Preference share purchase rights have been appropriately adjusted to reflect the effects of the common stock split discussed above. NOTE 10 Retained Earnings Changes in retained earnings for the years ended December 31, 1996, 1995 and 1994 are as follows: 1996 1995 1994 (In thousands) Balance at beginning of year $178,184 $168,050 $158,998 Net income 45,470 41,633 39,845 223,654 209,683 198,843 Deduct: Dividends declared -- Preferred stocks at required annual rates 787 792 797 Common stock 31,326 30,707 29,996 32,113 31,499 30,793 Balance at end of year $191,541 $178,184 $168,050 NOTE 11 Preferred Stocks 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. 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 stock: 4.50% $105.00 (b) --- --- 4.70% $102.00 (b) --- --- 5.10% $102.00 1,000 (c) $100.00 (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 requirements for each of the five years following December 31, 1996, is $100,000. NOTE 12 Long-term Debt and Indenture Provisions Long-term debt outstanding at December 31 is as follows: 1996 1995 1994 (In thousands) First mortgage bonds and notes: 9 1/8% Series, due May 15, 2006 $ 25,000 $ 50,000 $ 50,000 9 1/8% Series, due October 1, 2016 20,000 20,000 20,000 Pollution Control Refunding Revenue Bonds, Series 1992: Mercer County, North Dakota, 6.65%, due June 1, 2022 15,000 15,000 15,000 Morton County, North Dakota, 6.65%, due June 1, 2022 2,600 2,600 2,600 Richland County, Montana, 6.65%, due June 1, 2022 3,250 3,250 3,250 Secured Medium-Term Notes, Series A: 6.30%, due April 1, 1995 --- --- 10,000 6.95%, due April 1, 1996 --- 10,000 10,000 7.20%, due April 1, 1997 5,000 5,000 5,000 8.25%, due April 1, 2007 30,000 30,000 30,000 8.60%, due April 1, 2012 35,000 35,000 35,000 Total first mortgage bonds and notes 135,850 170,850 180,850 Pollution control lease and note obligation, 6.20%, due March 1, 2004 4,000 4,300 4,600 Senior notes: 7.35%, due July 31, 2002 5,000 5,000 --- 8.43%, due December 31, 2000 15,000 15,000 15,000 7.51%, expires October 9, 2003 3,000 --- --- 7.45%, due May 31, 2006 20,000 --- --- 7.60%, due November 3, 2008 15,000 --- --- Revolving lines of credit: 8.25%, expires December 31, 1998 30,000 21,500 17,000 Other revolving lines of credit at rates ranging from 6.03% to 8.50%, expiring at various dates ranging from October 6, 2001, through April 30, 2002 61,800 27,000 3,000 Term credit facilities: 5.95%, due March 31, 1997 --- 7,500 17,500 7.70%, due December 1, 2003 1,556 1,800 --- Other term credit facilities at rates ranging from 8.00% to 9.00%, due from June 30, 1999, through December 1, 2000 1,308 1,527 250 Other (94) (138) (157) Total long-term debt 292,420 254,339 238,043 Less current maturities and sinking fund requirements 11,754 16,987 20,350 Net long-term debt $280,666 $237,352 $217,693 Under the revolving lines of credit, the company has $120 million available, $91.8 million of which was outstanding at December 31, 1996. The amounts of scheduled long-term debt maturities and sinking fund requirements for the five years following December 31, 1996, aggregate $11.8 million in 1997; $44.5 million in 1998; $15.1 million in 1999; $18.4 million in 2000 and $10.9 million in 2001. 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 such Indenture, the company could have issued approximately $247 million of additional first mortgage bonds at December 31, 1996. Certain of the company's other debt instruments contain restrictive covenants all of which the company is in compliance with at December 31, 1996. NOTE 13 Income Taxes Income tax expense is summarized as follows: 1996 1995 1994 (In thousands) Current: Federal $12,617 $20,259 $11,995 State 3,272 3,801 2,644 Foreign 60 369 210 15,949 24,429 14,849 Deferred: Investment tax credit -- net (1,099) (1,028) (1,137) Income taxes -- Federal 1,139 (564) 4,589 State 120 220 532 Foreign (22) --- --- 138 (1,372) 3,984 Total income tax expense $16,087 $23,057 $18,833 Components of deferred tax assets and deferred tax liabilities recognized in the company's Consolidated Balance Sheets at December 31 are as follows: 1996 1995 1994 (In thousands) Deferred tax assets: Reserves for regulatory matters $ 38,404 $ 36,894 $ 33,076 Natural gas available under repurchase commitment 10,521 6,762 6,778 Accrued pension costs 7,814 7,039 5,646 Deferred investment tax credits 3,160 3,623 4,022 Accrued land reclamation 3,604 4,033 4,256 Natural gas costs refundable through rate adjustments --- 6,125 4,034 Other 13,499 11,321 10,220 Total deferred tax assets 77,002 75,797 68,032 Deferred tax liabilities: Depreciation and basis differences on property, plant and equipment 121,763 119,078 115,966 Basis differences on oil and natural gas producing properties 30,361 28,113 21,049 Natural gas contract settlement and restructuring costs 1,926 5,413 9,327 Long-term debt refinancing costs 4,688 4,524 4,745 Other 8,461 5,465 4,592 Total deferred tax liabilities 167,199 162,593 155,679 Net deferred income tax liability $(90,197) $(86,796) $(87,647) The following table reconciles the change in the net deferred income tax liability to the deferred income tax expense included in the Consolidated Statements of Income: 1996 1995 (In thousands) Net change in deferred income tax liability from the preceding table $ 3,401 $(851) Change in tax effects of income tax-related regulatory assets and liabilities 1,155 507 Deferred taxes associated with acquisitions (3,319) --- Deferred income tax expense for the period $ 1,237 $(344) Total income tax expense differs from the amount computed by applying the statutory federal income tax rate to income before taxes.

In 1991, the company received a notice of proposed deficiency from the IRS for the tax years 1983 through 1985 which proposed substantial additional income taxes, plus interest. In an alternative position contained in the notice of proposed deficiency, the IRS had claimed a lower level of taxes due, plus interest as well as penalties. In 1992 and 1995, similar notices of proposed deficiency were received for the years 1986 through 1988 and 1989 through 1991, respectively. Although the notices of proposed deficiency encompass a number of separate issues, the principal issue was related to the tax treatment of deductions claimed in connection with certain investments made by Knife River and Fidelity Oil. The company timely filed protests for the 1983 through 1991 tax years contesting the treatment proposed in the notices of proposed deficiency. In April 1996, the company and the IRS reached a settlement for the tax years 1983 through 1988, which should also result in settlement of related issues for the years 1989 through 1991. The company reflected the effect of the settlement in the third quarter of 1996 and, in addition, reversed reserves previously provided which were deemed to be no longer required. NOTE 14 Business Segment Data The company's operations are conducted through five business segments. The electric, natural gas distribution, natural gas transmission, construction materials and mining, and oil and natural gas production businesses are substantially all located within the United States. A description of these segments and their primary operations is presented on the inside front cover. Segment operating information at December 31, 1996, 1995 and 1994, is presented in the Consolidated Statements of Income.

Approximately 4 percent of construction materials and mining revenues in 1996 (4 percent in 1995 and 6 percent in 1994) represent Knife River's direct sales of lignite coal to the company. The company's share of Knife River's 1996 sales for use at the Coyote Station, a generating station jointly owned by the company and other utilities, was approximately 5 percent of construction materials and mining revenues in 1996. In 1995 and 1994, the company's share of Knife River's sales for use at the Coyote Station and the Big Stone Station, another generating station jointly owned by the company and other utilities, was 7 percent and 8 percent, respectively, of construction materials and mining revenues. In April 1996, KRC Holdings, Inc.(KRC Holdings), a wholly owned subsidiary of Knife River, purchased Baldwin Contracting Company, Inc. (Baldwin) of Chico, California. Baldwin is a major supplier of aggregate, asphalt and construction services in the northern Sacramento Valley and adjacent Sierra Nevada Mountains of northern California. Baldwin also provides a variety of construction services, primarily earth moving, grading, road and highway construction and maintenance. In June 1996, KRC Holdings purchased the assets of Medford Ready-Mix Concrete, Inc. located in Medford, Oregon. The acquired company serves the residential and small commercial construction market with ready-mixed concrete and aggregates. 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 15 Employee Benefit Plans The company has noncontributory defined benefit pension plans covering substantially all full-time employees. Pension benefits are based on employee's years of service and earnings. The company makes annual contributions to the plans consistent with the funding requirements of federal law and regulations. Pension expense is summarized as follows: 1996 1995 1994 (In thousands) Service cost/benefits earned during the year $ 3,852 $ 3,538 $ 4,035 Interest cost on projected benefit obligation 10,823 10,784 9,912 Loss (return) on plan assets (24,972) (37,185) 3,154 Net amortization and deferral 11,494 24,407 (15,410) Special termination benefit cost --- 853 --- Total pension costs 1,197 2,397 1,691 Less amounts capitalized 131 184 198 Total pension expense $ 1,066 $ 2,213 $ 1,493 The funded status of the company's plans at December 31 is summarized as follows: 1996 1995 1994 (In thousands) Projected benefit obligation: Vested $122,119 $121,879 $105,561 Nonvested 3,923 4,731 4,124 Accumulated benefit obligation 126,042 126,610 109,685 Provision for future pay increases 24,787 28,114 25,084 Projected benefit obligation 150,829 154,724 134,769 Plan assets at market value 185,872 170,793 139,332 (35,043) (16,069) (4,563) Plus: Unrecognized transition asset 7,336 8,326 9,315 Unrecognized net gains and prior service costs 35,848 14,686 2,466 Accrued pension costs $ 8,141 $ 6,943 $ 7,218 The projected benefit obligation was determined using an assumed discount rate of 7.50 percent (7.25 percent in 1995 and 8 percent in 1994) and assumed long-term rates for estimated compensation increases of 4.50 percent (4.50 percent in 1995 and 5 percent in 1994). The change in these assumptions had the effect of decreasing the projected benefit obligation at December 31, 1996, by $5 million but increasing the projected benefit obligation at December 31, 1995, by $12 million. The assumed long-term rate of return on plan assets is 8.50 percent. Plan assets consist primarily of debt and equity securities. In addition to providing pension benefits, the company has a policy of providing all eligible employees and dependents certain other postretirement benefits which include health care and life insurance upon their retirement. 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 increase retiree contributions each year by the excess of the expected health care cost trend rate over 6 percent. Postretirement benefits expense is summarized as follows: 1996 1995 1994 (In thousands) Service cost/benefits earned during the year $ 1,333 $1,226 $1,454 Interest cost on accumulated postretirement benefit obligation 4,701 4,777 4,584 Return on plan assets (2,491) (183) (176) Amortization of transition obligation 2,458 2,458 2,458 Net amortization and deferral 1,260 (719) 76 Total postretirement benefits cost 7,261 7,559 8,396 Less amounts capitalized 735 442 419 Total postretirement benefits expense $ 6,526 $7,117 $7,977 The funded status of the company's plans at December 31 is summarized as follows: 1996 1995 1994 (In thousands) Accumulated postretirement benefit obligation: Retirees eligible for benefits $40,775 $43,543 $36,985 Active employees fully eligible for benefits --- 66 22 Active employees not fully eligible 24,833 26,229 22,898 Total 65,608 69,838 59,905 Plan assets at market value 21,712 15,095 9,938 43,896 54,743 49,967 Less: Unrecognized transition obligation 39,322 41,779 44,237 Unrecognized net losses 3,693 12,066 4,896 Accrued postretirement benefits cost $ 881 $ 898 $ 834 The health plan cost trend rate assumed in determining the accumulated postretirement benefit obligation at December 31, 1996, was 9 percent decreasing by 1 percent per year until an ultimate rate of 6 percent is reached in 1999 and remaining level thereafter. The health plan cost trend rate assumption has a significant effect on the amounts reported. To illustrate, increasing the assumed health plan cost trend rates by 1 percent each year would increase the accumulated postretirement benefit obligation as of December 31, 1996, by $3.1 million and the aggregate of the service and interest cost components of postretirement benefits expense by $233,000. The accumulated postretirement benefit obligation was determined using an assumed discount rate of 7.50 percent at December 31, 1996, 7.25 percent at December 31, 1995, and 8 percent at December 31, 1994, and assumed long-term rates for estimated compensation increases, as they apply to life insurance benefits, of 4.50 percent at December 31, 1996 and 1995, and 5 percent at December 31, 1994. The change in these assumptions had the effect of decreasing the accumulated postretirement benefit obligation at December 31, 1996, by $2 million but increasing the accumulated postretirement benefit obligation at December 31, 1995, by $7 million. The assumed long-term rate of return on assets is 7.50 percent. Plan assets consist primarily of certain life insurance products of which the return depends on the performance of underlying debt and equity securities. 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 $2.2 million in 1996, $1.9 million in 1995 and $1.7 million in 1994. The company has a Key Employee Stock Option Plan (KESOP). The company accounts for the KESOP in accordance with APB Opinion No. 25 under which no compensation expense has been recognized. The company is authorized to grant options for up to 1.2 million shares of common stock and has granted options on 484,540 shares through December 31, 1996. Under the KESOP the option price equals the stock's market value on the date of grant. Options automatically vest after nine years, but the KESOP provides for accelerated vesting based upon the attainment of certain performance goals or upon change in control and expire 10 years after the date of grant. The company has contributed $5.7 million to a trust established to fund its commitment under the KESOP. Pro forma net income and earnings per common share calculated using the provisions of SFAS No. 123, "Accounting for Stock-Based Compensation" have not been presented because such amounts are not materially different than actual amounts reported. A summary of the status of the KESOP at December 31, 1996, 1995 and 1994, and changes during the years then ended are as follows: 1996 1995 1994 Weighted Weighted Weighted Average Average Average Exercise Exercise Exercise Shares Price Shares Price Shares Price Balance at 468,737 $17.48 192,284 $15.82 265,964 $15.82 beginning of year Granted --- --- 294,956 18.50 --- --- Forfeited --- --- (2,700) 20.83 (73,680) 15.80 Exercised (44,760) 15.75 (15,803) 15.75 --- --- Balance at end of year 423,977 17.66 468,737 17.48 192,284 15.82 Exercisable at end of year 93,764 $15.75 138,524 $15.75 --- --- Exercise prices on options outstanding at December 31, 1996, range from $15.75 to $18.50 with a weighted average remaining contractual life of approximately 7 years. The weighted average fair value of each option granted in 1995 is $2.67. The fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model. The assumptions used to estimate the fair value of options granted in 1995 were a risk-free interest rate of 7.80 percent, an expected dividend yield of 5.80 percent, an expected life of 10 years and expected volatility of 15.80 percent. The company has Tax Deferred Compensation Savings Plans for eligible employees. Each participant may contribute amounts up to 15 percent of eligible compensation, subject to certain limitations. The company contributes an amount equal to 50 percent of the participant's savings contribution up to a maximum of 6 percent of such participant's contribution. Company contributions were $1.9 million in 1996, 1995 and 1994. NOTE 16 Partnership Investment In September 1995, KRC Holdings through its wholly owned subsidiary, Knife River Hawaii, Inc., acquired a 50 percent interest in Hawaiian Cement, which was previously owned by Lone Star Industries, Inc. Hawaiian Cement is one of the largest construction materials suppliers in Hawaii serving four of the islands. Hawaiian Cement's operations include construction aggregate mining, ready-mixed concrete and cement manufacturing and distribution. Hawaiian Cement, headquartered in Honolulu, Hawaii, is a partnership which is also 50 percent owned by Adelaide Brighton Ltd. of Adelaide, Australia. The company's net investment in Hawaiian Cement is included in "Investments" in the accompanying Consolidated Balance Sheets at December 31, 1996 and 1995, while its share of operating results is included in "Other income -- net" in the accompanying Consolidated Statements of Income for the years ended December 31, 1996 and 1995. Summarized financial information for Hawaiian Cement, which is not consolidated and is accounted for by the equity method, as of and for the year ended December 31, 1996, and as of and for the four months ended December 31, 1995, as applicable, is as follows: 1996 1995 (In thousands) Current assets $17,316 $19,531 Property, plant and equipment, net 52,316 70,544 Current liabilities 10,128 14,209 Other liabilities 14,954 15,736 Net sales 70,059 24,433 Operating margin 9,900 5,096 Income before income taxes 5,373 2,757 The company's investment in Hawaiian Cement exceeds the underlying net assets by $13.2 million. The excess is being amortized over 30 years. NOTE 17 Jointly Owned Facilities The consolidated financial statements include the company's 22.70 percent and 25 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 providing its own financing of 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: 1996 1995 1994 (In thousands) Big Stone Station: Utility plant in service $ 48,907 $ 47,687 $ 46,923 Accumulated depreciation 26,676 27,026 25,505 $ 22,231 $ 20,661 $ 21,418 Coyote Station: Utility plant in service $122,320 $122,126 $ 121,784 Accumulated depreciation 52,721 49,296 45,546 $ 69,599 $ 72,830 $ 76,238 NOTE 18 Quarterly Data (Unaudited) The following unaudited information shows selected items by quarter for the years 1996 and 1995: First Second Third Fourth Quarter Quarter Quarter Quarter (In thousands, except per share amounts) 1996 Operating revenues $126,529 $110,213 $133,759 $144,200 Operating expenses 98,447 90,012 103,038 111,679 Operating income 28,082 20,201 30,721 32,521 Net income 13,135 8,600 8,495 15,240 Earnings per common share .45 .30 .29 .53 Average common shares outstanding 28,477 28,477 28,477 28,477 1995 Operating revenues $116,518 $111,267 $113,945 $122,516 Operating expenses 94,047 91,690 91,606 96,327 Operating income 22,471 19,577 22,339 26,189 Net income 10,272 8,662 10,472 12,227 Earnings per common share .35 .30 .36 .42 Average common shares outstanding 28,477 28,477 28,477 28,477 Some of the company's 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 19 Oil and Natural Gas Activities (Unaudited) Fidelity Oil is involved in the acquisition, exploration, development and production of oil and natural gas properties. Fidelity's operations vary from the acquisition of producing properties with potential development opportunities to exploration and are located throughout the United States, the Gulf of Mexico and Canada. Fidelity Oil shares revenues and expenses from the development of specified properties in proportion to its interests. In 1994, Williston Basin undertook a drilling program designed to increase production and to gain updated data from which to assess the future production capabilities of natural gas reserves held primarily in Montana. In late 1994, upon analysis of the results of this program, it was determined that the future production related to these properties can be accelerated and, as a result, the economic value of these reserves has become material to the company's consolidated oil and natural gas production operations. Therefore, beginning in 1994, the tables set forth below include information related to Williston Basin's natural gas production activities. The following information includes the company's proportionate share of all its oil and natural gas interests. The following table sets forth capitalized costs and related accumulated depreciation, depletion and amortization related to oil and natural gas producing activities at December 31: 1996 1995 1994 (In thousands) Subject to amortization $223,409 $173,501 $155,303 Not subject to amortization 6,792 8,831 8,530 Total capitalized costs 230,201 182,332 163,833 Accumulated depreciation, depletion and amortization 71,554 49,498 54,376 Net capitalized costs $158,647 $132,834 $109,457 Net capital expenditures, including those not subject to amortization, related to oil and natural gas producing activities for the 12 months ended December 31 are as follows: 1996 1995 1994 (In thousands) Acquisitions $23,284 $ 9,159 $ 3,182 Exploration 8,101 7,678 12,656 Development 19,979 24,955 20,247 Net capital expenditures $51,364 $41,792 $36,085 The following summary reflects income resulting from the company's operations of oil and natural gas producing activities, excluding corporate overhead and financing costs, for the 12 months ended December 31: 1996 1995 1994 (In thousands) Revenues* $75,335 $53,484 $45,053 Production costs 21,296 16,888 18,463 Depreciation, depletion and amortization 25,629 19,058 13,926 Pretax income 28,410 17,538 12,664 Income tax expense 10,875 6,397 4,257 Results of operations for producing activities $17,535 $11,141 $ 8,407 * Includes $7.0 million, $4.7 million and $7.1 million of revenues for 1996, 1995 and 1994, respectively, related to Williston Basin's natural gas production activities which are included in "Natural gas" operating revenues on the Consolidated Statements of Income. The following table summarizes the company's estimated quantities of proved developed oil and natural gas reserves at December 31, 1996, 1995 and 1994, and reconciles the changes between these dates. Estimates of economically recoverable oil and natural gas 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. 1996 1995 1994 Natural Natural Natural Oil Gas Oil Gas Oil Gas (In thousands of barrels/Mcf) Proved developed and undeveloped reserves: Balance at beginning of year 14,200 179,000 12,500 154,200 11,200 50,300 Production (2,100) (20,400) (2,000) (17,500) (1,600) (9,200) Extensions and discoveries 600 27,000 1,800 23,800 1,300 17,800 Purchases of proved reserves 2,900 9,900 1,100 6,700 600 2,900 Sales of reserves in place (700) (3,700) (300) (200) (400) (2,700) Revisions to previous estimates due to improved secondary recovery techniques and/or changed economic conditions 1,200 8,400 1,100 12,000 1,400 95,100* Balance at end of year 16,100 200,200 14,200 179,000 12,500 154,200 *Includes 99,300 MMcf of Williston Basin's natural gas reserves.

Virtually all of the company's interests in oil and natural gas reserves are located in the continental United States. Reserve interests at December 31, 1996, applicable to the company's $2.0 million net investment in oil and natural gas properties located in Canada comprise approximately 2 percent of the total reserves. The standardized measure of the company's estimated discounted future net cash flows of total proved reserves associated with its various oil and natural gas interests at December 31 is as follows: 1996 1995 1994 (In thousands) Future net cash flows before income taxes $580,300 $267,300 $197,900 Future income tax expenses 194,200 76,100 48,800 Future net cash flows 386,100 191,200 149,100 10% annual discount for estimated timing of cash flows 152,100 70,300 54,200 Discounted future net cash flows relating to proved oil and natural gas reserves $234,000 $120,900 $ 94,900 The following are the sources of change in the standardized measure of discounted future net cash flows by year: 1996 1995 1994 (In thousands) Beginning of year $120,900 $ 94,900 $ 71,600 Net revenues from production (54,000) (36,400) (23,800) Change in net realization 125,800 26,300 (4,100) Extensions, discoveries and improved recovery, net of future production-related costs 43,500 31,200 31,700 Purchases of proved reserves 49,600 10,900 5,800 Sales of reserves in place (6,700) (1,000) (3,700) Changes in estimated future development costs -- net of those incurred during the year (2,400) (8,900) (2,900) Accretion of discount 16,900 12,300 8,300 Net change in income taxes (69,200) (17,100) (4,000) Revisions of previous quantity estimates 8,700 8,900 16,500* Other 900 (200) (500) Net change 113,100 26,000 23,300 End of year $234,000 $120,900 $ 94,900 *Includes $19.1 million related to Williston Basin's natural gas reserves. The estimated discounted future cash inflows from estimated future production of proved reserves were computed using year-end oil and natural gas 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. To MDU Resources Group, Inc.
