ITEMS 1 AND 2. BUSINESS AND PROPERTIES General MDU Resources Group, Inc. (Company) is a diversified natural resource company which was incorporated under the laws of the State of Delaware in 1924. Its principal executive offices are at Schuchart Building, 918 East Divide Avenue, Bismarck, North Dakota 58501, telephone (701) 222-7900. Montana-Dakota Utilities Co. (Montana-Dakota), the public utility division of the Company, provides electric and/or natural gas and propane distribution service at retail to 256 communities in North Dakota, eastern Montana, northern and western South Dakota and northern Wyoming, and owns and operates electric power generation and transmission facilities. The Company, through its wholly owned subsidiary, Centennial Energy Holdings, Inc. (Centennial), owns Williston Basin Interstate Pipeline Company (Williston Basin), Knife River Corporation (Knife River), the Fidelity Oil Group (Fidelity Oil) and Utility Services, Inc. (Utility Services). Williston Basin produces natural gas and provides underground storage, transportation and gathering services through an interstate pipeline system serving Montana, North Dakota, South Dakota and Wyoming and, through its wholly owned subsidiary, Prairielands Energy Marketing, Inc. (Prairielands), seeks new energy markets while continuing to expand present markets for natural gas and propane. Knife River, through its wholly owned subsidiary, KRC Holdings, Inc. (KRC Holdings) and its subsidiaries, surface mines and markets aggregates and related construction materials in Alaska, California, Hawaii and Oregon. In addition, Knife River surface mines and markets low sulfur lignite coal at mines located in Montana and North Dakota. Fidelity Oil is comprised of Fidelity Oil Co. and Fidelity Oil Holdings, Inc., which own oil and natural gas interests throughout the United States, the Gulf of Mexico and Canada through investments with several oil and natural gas producers. Utility Services, through its wholly owned subsidiaries, International Line Builders, Inc. and High Line Equipment, Inc., both acquired on July 1, 1997, installs and repairs electric transmission and distribution power lines in the western United States and Hawaii and provides related supplies and equipment. The significant industries within the Company's retail utility service area consist of agriculture and the related processing of agricultural products and energy-related activities such as oil and natural gas production, oil refining, coal mining and electric power generation. As of December 31, 1997, the Company had 2,218 full-time employees with 84 employed at MDU Resources Group, Inc., including Fidelity Oil, 1,011 at Montana-Dakota, 292 at Williston Basin, including Prairielands, 522 at Knife River's construction materials operations, 147 at Knife River's coal operations and 162 at Utility Services. Approximately 501 and 83 of the Montana-Dakota and Williston Basin employees, respectively, are represented by the International Brotherhood of Electrical Workers (IBEW). Labor contracts with such employees are in effect through May 1999, for both Montana-Dakota and Williston Basin. Knife River has a labor contract through August 1998, with the United Mine Workers of America, which represents its coal operation's hourly workforce aggregating 90 employees. In addition, Knife River has 14 labor contracts which represent 243 of its construction materials employees. Utility Services has 2 labor contracts representing the majority of its employees. The financial results and data applicable to each of the Company's business segments as well as their financing requirements are set forth in Item 7 -- "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Notes to Consolidated Financial Statements. Any reference to the Company's Consolidated Financial Statements and Notes thereto shall be to pages 25 through 49 in the Company's Annual Report to Stockholders for 1997 (Annual Report), which are incorporated by reference herein. ENERGY DISTRIBUTION OPERATIONS AND PROPERTY (MONTANA-DAKOTA) Electric Generation, Transmission and Distribution General -- Montana-Dakota provides electric service at retail, serving over 113,000 residential, commercial, industrial and municipal customers located in 177 communities and adjacent rural areas as of December 31, 1997. The principal properties owned by Montana- Dakota for use in its electric operations include interests in seven electric generating stations, as further described under "System Supply and System Demand," and approximately 3,100 and 3,900 miles of transmission and distribution lines, respectively. Montana-Dakota has obtained and holds valid and existing franchises authorizing it to conduct its electric operations in all of the municipalities it serves where such franchises are required. As of December 31, 1997, Montana-Dakota's net electric plant investment approximated $283.9 million. All of Montana-Dakota's electric properties, with certain exceptions, are subject to the lien of the Indenture of Mortgage dated May 1, 1939, as supplemented, amended and restated, from the Company to The Bank of New York and W. T. Cunningham, successor trustees. The electric operations of Montana-Dakota are subject to regulation by the Federal Energy Regulatory Commission (FERC) under provisions of the Federal Power Act with respect to the transmission and sale of power at wholesale in interstate commerce, interconnections with other utilities, the issuance of securities, accounting and other matters. Retail rates, service, accounting and, in certain cases, security issuances are also subject to regulation by the North Dakota Public Service Commission (NDPSC), Montana Public Service Commission (MPSC), South Dakota Public Utilities Commission (SDPUC) and Wyoming Public Service Commission (WPSC). The percentage of Montana-Dakota's 1997 electric utility operating revenues by jurisdiction is as follows: North Dakota -- 60 percent; Montana -- 22 percent; South Dakota -- 8 percent and Wyoming -- 10 percent. System Supply and System Demand -- Through an interconnected electric system, Montana-Dakota serves markets in portions of the following states and major communities -- western North Dakota, including Bismarck, Dickinson and Williston; eastern Montana, including Glendive and Miles City; and northern South Dakota, including Mobridge. The interconnected system consists of seven on-line electric generating stations which have an aggregate turbine nameplate rating attributable to Montana- Dakota's interest of 393,488 Kilowatts (kW) and a total summer net capability of 421,060 kW. Montana-Dakota's four principal generating stations are steam-turbine generating units using coal for fuel. The nameplate rating for Montana-Dakota's ownership interest in these four stations (including interests in the Big Stone Station and the Coyote Station aggregating 22.7 percent and 25.0 percent, respectively) is 327,758 kW. The balance of Montana- Dakota's interconnected system electric generating capability is supplied by three combustion turbine peaking stations. Additionally, Montana-Dakota has contracted to purchase through October 31, 2006, 66,400 kW of participation power from Basin Electric Power Cooperative (Basin) for its interconnected system. The following table sets forth details applicable to the Company's electric generating stations: 1997 Net Generation Nameplate Summer (kilowatt- Generating Rating Capability hours in Station Type (kW) (kW) thousands) North Dakota -- Coyote* Steam 103,647 106,750 507,714 Heskett Steam 86,000 102,000 369,791 Williston Combustion Turbine 7,800 8,900 (62)** South Dakota -- Big Stone* Steam 94,111 101,460 741,280 Montana -- Lewis & Clark Steam 44,000 49,150 184,408 Glendive Combustion Turbine 34,780 31,200 13,484 Miles City Combustion Turbine 23,150 21,600 10,155 393,488 421,060 1,826,770 * Reflects Montana-Dakota's ownership interest. ** Station use, to meet MAPP's accreditation requirements, exceeded generation. Virtually all of the current fuel requirements of the Coyote, Heskett and Lewis & Clark stations are met with coal supplied by Knife River under various long-term contracts. See "Construction Materials and Mining Operations and Property (Knife River) -- Coal Operations" for a discussion of a suit and arbitration filed by the Co-owners of the Coyote Station against Knife River and the Company. The majority of the Big Stone Station's fuel requirements are currently being met with coal supplied by Westmoreland Resources, Inc. under a contract which expires on December 31, 1999. During the years ended December 31, 1993, through December 31, 1997, the average cost of coal consumed, including freight, per million British thermal units (Btu) at Montana-Dakota's electric generating stations (including the Big Stone and Coyote stations) in the interconnected system and the average cost per ton, including freight, of the coal so consumed was as follows: Years Ended December 31, 1997 1996 1995 1994 1993 Average cost of coal per million Btu $.95 $.93 $.94 $.97 $.96 Average cost of coal per ton $14.22 $13.64 $12.90 $12.88 $12.78 The maximum electric peak demand experienced to date attributable to sales to retail customers on the interconnected system was 412,700 kW in August 1995. Due to a cooler than normal summer, the 1997 summer peak was only 404,566 kW. The 1997 summer peak, assuming normal weather, was previously forecasted to have been approximately 416,600 kW. Montana-Dakota's latest forecast for its interconnected system indicates that its annual peak will continue to occur during the summer and the peak demand growth rate through 2003 will approximate 1.3 percent annually. Montana- Dakota's latest forecast indicates that its kilowatt-hour (kWh) sales growth rate, on a normalized basis, through 2003 will approximate 1.0 percent annually. Montana-Dakota currently estimates that it has adequate capacity available through existing generating stations and long-term firm purchase contracts until the year 2000. If additional capacity is needed in 2000 or after, it will be met through the addition of combustion turbine peaking stations and purchases from the Mid-Continent Area Power Pool (MAPP) on an intermediate-term basis. Montana-Dakota has major interconnections with its neighboring utilities, all of which are MAPP members. Montana-Dakota considers these interconnections adequate for coordinated planning, emergency assistance, exchange of capacity and energy and power supply reliability. Through a separate electric system (Sheridan System), Montana- Dakota serves Sheridan, Wyoming and neighboring communities. The maximum peak demand experienced to date and attributable to Montana-Dakota sales to retail consumers on that system was approximately 46,600 kW and occurred in December 1983. Due to a peak shaving load management system, Montana-Dakota estimates this annual peak will not be exceeded through 1999. The Sheridan System is supplied through an interconnection with Black Hills Power and Light Company under a ten-year power supply contract which allows for the purchase of up to 55,000 kW of capacity. Regulation and Competition -- The electric utility industry can be expected to continue to become increasingly competitive due to a variety of regulatory, economic and technological changes. As a result of competition in electric generation, wholesale power markets have become increasingly competitive and evaluations are ongoing concerning retail competition. In April 1996, the FERC issued its final rules (Order No. 888 and 889) on wholesale electric transmission open access and recovery of stranded costs. Montana-Dakota filed proposed tariffs with the FERC in compliance with Order 888, which became effective in July 1996. Montana-Dakota is awaiting final approval of the proposed tariffs by the FERC. In December 1996, Montana-Dakota filed a Request for Waiver of the requirements of FERC Order No. 889 as it relates to the Standards of Conduct. The Standards of Conduct require companies to physically separate their transmission operations/reliability functions from their marketing/merchant functions. On May 29, 1997, Montana-Dakota's request was granted. In a related matter, in March 1996, the MAPP, of which Montana- Dakota is a member, filed a restated operating agreement with the FERC. The FERC approved MAPP's restated agreement, excluding MAPP's market-based rate proposal, effective November 1996. The FERC has requested additional information from the MAPP on its market-based rate proposal before it will take further action. Three of the four states which regulate the Company's electric operations continue to evaluate and/or implement utility regulations with respect to retail competition (retail wheeling). Additionally, federal legislation addressing this issue has been introduced. In April 1997, the Montana legislature passed an electric industry restructuring bill. The bill provides for full customer choice of electric supplier by July 1, 2002, stranded cost recovery and other provisions. Based on the provisions of such restructuring bill, because the Company's utility division operates in more than one state, the Company has the option of deferring its transition to full customer choice until 2006. In its 1997 legislative session, the North Dakota legislature established an Electric Industry Competition Committee to study over a six-year period the impact of competition on the generation, transmission and distribution of electric energy in the State. In 1997, the WPSC selected a consultant to perform a study on the impact of electric restructuring in Wyoming. The study found no material economic benefits; however, the WPSC is continuing to evaluate the economic impact of retail wheeling on the State of Wyoming. The SDPUC has not initiated any proceedings to date concerning retail competition or electric industry restructuring. Although Montana-Dakota is unable to predict the outcome of such regulatory proceedings or legislation, or the extent to which retail competition may occur, Montana-Dakota is continuing to take steps to effectively operate in an increasingly competitive environment. Fuel adjustment clauses contained in North Dakota and South Dakota jurisdictional electric rate schedules allow Montana-Dakota to reflect increases or decreases in fuel and purchased power costs (excluding demand charges) on a timely basis. Expedited rate filing procedures in Wyoming allow Montana-Dakota to timely reflect increases or decreases in fuel and purchased power costs as well as changes in load management costs. In Montana (22 percent of electric revenues), such cost changes are includible in general rate filings. Capital Requirements -- The following schedule (in millions of dollars) summarizes the 1997 actual and 1998 through 2000 anticipated net capital expenditures applicable to Montana-Dakota's electric operations: Actual Estimated 1997 1998 1999 2000 Production $ 4.7 $ 5.8 $ 5.5 $ 5.9 Transmission 2.6 2.8 2.7 2.9 Distribution, General and Common 11.4 9.0 8.2 8.2 $18.7 $17.6 $16.4 $17.0 Environmental Matters -- Montana-Dakota's electric operations, are subject to extensive federal, state and local laws and regulations providing for air, water and solid waste pollution control; state facility-siting regulations; zoning and planning regulations of certain state and local authorities; federal health and safety regulations and state hazard communication standards. Montana-Dakota believes it is in substantial compliance with all existing environmental regulations and permitting requirements. The U.S. Clean Air Act (Clean Air Act) requires electric generating facilities to reduce sulfur dioxide emissions by the year 2000 to a level not exceeding 1.2 pounds per million Btu. Montana-Dakota's baseload electric generating stations are coal fired. All of these stations, with the exception of the Big Stone Station, are either equipped with scrubbers or utilize an atmospheric fluidized bed combustion boiler, which permits them to operate with emission levels less than the 1.2 pounds per million Btu. The emissions requirement at the Big Stone Station is expected to be met by switching to competitively priced lower sulfur ("compliance") coal. In addition, the Clean Air Act limits the amount of nitrous oxide emissions. Montana-Dakota's generating stations, with the exception of the Big Stone Station, are within the limitations set by the United States Environmental Protection Agency (EPA). The co-owners of the Big Stone Station have determined the modifications necessary at the Big Stone Station. Montana-Dakota believes that the cost of such modifications will not have a material effect on its results of operations. Governmental regulations establishing environmental protection standards are continuously evolving and, therefore, the character, scope, cost and availability of the measures which will permit compliance with evolving laws or regulations, cannot now be accurately predicted. Montana-Dakota did not incur any significant environmental expenditures in 1997 and does not expect to incur any significant capital expenditures related to environmental compliance through 2000. Retail Natural Gas and Propane Distribution General -- Montana-Dakota sells natural gas and propane at retail, serving over 200,000 residential, commercial and industrial customers located in 141 communities and adjacent rural areas as of December 31, 1997, and provides natural gas transportation services to certain customers on its system. These services are provided through a distribution system aggregating over 4,200 miles. Montana-Dakota has obtained and holds valid and existing franchises authorizing it to conduct natural gas and propane distribution operations in all of the municipalities it serves where such franchises are required. As of December 31, 1997, Montana-Dakota's net natural gas and propane distribution plant investment approximated $79.5 million. All of Montana-Dakota's natural gas distribution properties, with certain exceptions, are subject to the lien of the Indenture of Mortgage dated May 1, 1939, as supplemented, amended and restated, from the Company to The Bank of New York and W. T. Cunningham, successor trustees. The natural gas and propane distribution operations of Montana-Dakota are subject to regulation by the NDPSC, MPSC, SDPUC and WPSC regarding retail rates, service, accounting and, in certain instances, security issuances. The percentage of Montana-Dakota's 1997 natural gas and propane utility operating revenues by jurisdiction is as follows: North Dakota -- 43 percent; Montana -- 29 percent; South Dakota -- 21 percent and Wyoming -- 7 percent. System Supply, System Demand and Competition -- Montana-Dakota serves retail natural gas markets, consisting principally of residential and firm commercial space and water heating users, in portions of the following states and major communities -- North Dakota, including Bismarck, Dickinson, Williston, Minot and Jamestown; eastern Montana, including Billings, Glendive and Miles City; western and north-central South Dakota, including Rapid City, Pierre and Mobridge; and northern Wyoming, including Sheridan. These markets are highly seasonal and sales volumes depend on the weather. The following table reflects Montana-Dakota's natural gas and propane sales and natural gas transportation volumes during the last five years: Years Ended December 31, 1997 1996 1995 1994 1993 Mdk (thousands of decatherms) Sales: Residential 20,126 22,682 20,135 19,039 19,565 Commercial 13,799 15,325 13,509 12,403 11,196 Industrial 395 276 295 398 386 Total 34,320 38,283 33,939 31,840 31,147 Transportation: Commercial 1,612 1,677 1,742 2,011 3,461 Industrial 8,455 7,746 9,349 7,267 9,243 Total 10,067 9,423 11,091 9,278 12,704 Total Throughput 44,387 47,706 45,030 41,118 43,851 The restructuring of the natural gas industry, as described under "Natural Gas Transmission Operations and Property (Williston Basin)", has resulted in additional competition in retail natural gas markets. In response to these changed market conditions Montana-Dakota has established various natural gas transportation service rates for its distribution business to retain interruptible commercial and industrial load. Certain of these services include transportation under flexible rate schedules and capacity release contracts whereby Montana-Dakota's interruptible customers can avail themselves of the advantages of open access transportation on the Williston Basin system. These services have enhanced Montana-Dakota's competitive posture with alternate fuels, although certain of Montana-Dakota's customers have the potential of bypassing Montana-Dakota's distribution system by directly accessing Williston Basin's facilities. Montana-Dakota acquires all of its system requirements directly from producers, processors and marketers. Such natural gas is supplied under firm contracts, specifying market-based pricing, and is transported under firm transportation agreements by Williston Basin and Northern Gas Company and, with respect to Montana-Dakota's north- central South Dakota and south-central North Dakota markets, by South Dakota Intrastate Pipeline Company and Northern Border Pipeline Company, respectively. Montana-Dakota has also contracted with Williston Basin to provide firm storage services which enable Montana- Dakota to purchase natural gas at more uniform daily volumes throughout the year and, thus, meet winter peak requirements as well as allow it to better manage its natural gas costs. Montana-Dakota estimates that, based on supplies of natural gas currently available through its suppliers and expected to be available, it will have adequate supplies of natural gas to meet its system requirements for the next five years. Regulatory Matters -- Montana-Dakota's retail natural gas rate schedules contain clauses permitting monthly adjustments in rates based upon changes in natural gas commodity, transportation and storage costs. Current regulatory practices allow Montana-Dakota to recover increases or refund decreases in such costs within 24 months from the time such changes occur. Capital Requirements -- Montana-Dakota's net capital expenditures aggregated $7.7 million for natural gas and propane distribution facilities in 1997 and are anticipated to be approximately $7.7 million, $8.8 million and $7.5 million in 1998, 1999 and 2000, respectively. Environmental Matters -- Montana-Dakota's natural gas and propane distribution operations are generally subject to extensive federal, state and local environmental, facility siting, zoning and planning laws and regulations. Except as set forth below, Montana-Dakota believes it is in substantial compliance with those regulations. Montana-Dakota and Williston Basin discovered polychlorinated biphenyls (PCBs) in portions of their natural gas systems and informed the 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. CENTENNIAL ENERGY HOLDINGS, INC. NATURAL GAS TRANSMISSION OPERATIONS AND PROPERTY (WILLISTON BASIN) General -- Williston Basin owns and operates over 3,600 miles of transmission, gathering and storage lines and 22 compressor stations located in the states of Montana, North Dakota, South Dakota and Wyoming. Through three underground storage fields located in Montana and Wyoming, storage services are provided to local distribution companies, producers, suppliers and others, and serve to enhance system deliverability. Williston Basin's system is strategically located near five natural gas producing basins making natural gas supplies available to Williston Basin's transportation and storage customers. In addition, Williston Basin produces natural gas from owned reserves which is sold to others or used by Williston Basin for its operating needs. Williston Basin has interconnections with seven pipelines in Wyoming, Montana and North Dakota which provide for supply and market access. Prairielands, a subsidiary of Williston Basin, seeks new energy markets while continuing to expand present markets for natural gas. Its activities include buying and selling natural gas and arranging transportation services to end users, pipelines and local distribution companies. In addition, Prairielands operates two retail propane operations in north central and southeastern North Dakota. At December 31, 1997, the net natural gas transmission plant investment, inclusive of its transmission, storage, gathering, production, marketing and propane facilities, was approximately $167.5 million. Under the Natural Gas Act (NGA), as amended, Williston Basin is subject to the jurisdiction of the FERC regarding certificate, rate and accounting matters applicable to natural gas purchases, sales, transportation, gathering and related storage operations. System Demand and Competition -- The natural gas transmission industry, although regulated, is very competitive. Beginning in the mid-1980s customers began switching their natural gas service from a bundled merchant service to transportation, and with the implementation of Order 636 which unbundled pipelines' services, this transition was accelerated. This change reflects most customers' willingness to purchase their natural gas supply from producers, processors or marketers rather than pipelines. Williston Basin competes with several pipelines for its customers' transportation business and at times will have to discount rates in an effort to retain market share. However, the strategic location of Williston Basin's system near five natural gas producing basins and the availability of underground storage and gathering services provided by Williston Basin along with interconnections with other pipelines serve to enhance Williston Basin's competitive position. Although a significant portion of Williston Basin's firm customers, including Montana-Dakota, have relatively secure residential and commercial end-users, virtually all have some price- sensitive end-users that could switch to alternate fuels. Williston Basin transports essentially all of Montana-Dakota's natural gas under firm transportation agreements, which in 1997, represented 87 percent of Williston Basin's currently subscribed firm transportation capacity. In November 1996, Montana-Dakota executed a new firm transportation agreement with Williston Basin for a term of five years which began in July 1997. In addition, in July 1995, Montana-Dakota entered a twenty-year contract with Williston Basin to provide firm storage services to facilitate meeting Montana-Dakota's winter peak requirements. For additional information regarding Williston Basin's transportation for 1995 through 1997, see Item 7 -- "Management's Discussion and Analysis of Financial Condition and Results of Operations." System Supply -- Williston Basin's underground storage facilities have a certificated storage capacity of approximately 353,300 million cubic feet (MMcf), including 28,900 MMcf and 46,300 MMcf of recoverable and nonrecoverable native gas, respectively. Williston Basin's storage facilities enable its customers to purchase natural gas at more uniform daily volumes throughout the year and, thus, facilitate meeting winter peak requirements. Natural gas supplies from traditional regional sources have declined during the past several years and such declines are anticipated to continue. As a result, Williston Basin anticipates that a potentially significant amount of the future supply needed to meet its customers' demands will come from non-traditional, off- system sources. Williston Basin expects to facilitate the movement of these supplies by making available its transportation and storage services. Opportunities may exist to increase transportation and storage services through system expansion or other pipeline interconnections or enhancements which could provide substantial future benefits to Williston Basin. Natural Gas Production -- Williston Basin owns in fee or holds natural gas leases and operating rights primarily applicable to the shallow rights (above 2,000 feet) in the Cedar Creek Anticline in southeastern Montana and to all rights in the Bowdoin area located in north-central Montana. Information on Williston Basin's natural gas production, average sales prices and production costs per Mcf related to its natural gas interests for 1997, 1996 and 1995 is as follows: 1997 1996 1995 Production (MMcf) 7,215 6,324 5,184 Average sales price $1.30 $1.11 $.91 Production costs, including taxes $.46 $.43 $.30 Williston Basin's gross and net productive well counts and gross and net developed and undeveloped acreage for its natural gas interests at December 31, 1997, are as follows: Gross Net Productive Wells 533 483 Developed Acreage (000's) 234 213 Undeveloped Acreage (000's) 45 40 The following table shows the results of natural gas development wells drilled and tested during 1997, 1996 and 1995: 1997 1996 1995 Productive 20 32 17 Dry Holes --- --- --- Total 20 32 17 At December 31, 1997, there were no wells in the process of drilling. Williston Basin's recoverable proved developed and undeveloped natural gas reserves approximated 127.3 Bcf at December 31, 1997. These amounts are supported by a report dated January 12, 1998, prepared by Ralph E. Davis Associates, Inc., an independent firm of petroleum and natural gas engineers. Since 1993, Williston Basin has engaged in a long-term developmental drilling program to enhance the performance of its investment in natural gas reserves. As a result of this effort, 1997 production levels reached 6.9 MMdk, up 79 percent from 1993. The production increases from these reserves are expected to provide additional natural gas supplies for Prairielands to enable it to enhance its marketing efforts. For additional information related to Williston Basin's natural gas interests, see Note 18 of Notes to Consolidated Financial Statements. 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 totaled approximately $19 million or, under its alternative pricing theory, approximately $39 million. On June 26, 1997, the Federal District Court issued its order awarding Moncrief damages of approximately $15.6 million. On July 25, 1997, the Federal District Court issued an order limiting Moncrief's reimbursable costs to post-judgment interest, instead of both pre- and post-judgment interest as Moncrief had sought. On August 25, 1997, Moncrief filed a notice of appeal with the United States Court of Appeals for the Tenth Circuit related to the Federal District Court's orders. On September 2, 1997, Williston Basin and the Company filed a notice of cross-appeal. Williston Basin believes that it is entitled to recover from ratepayers virtually all of the costs ultimately incurred as a result of these orders as gas supply realignment transition costs pursuant to the provisions of the FERC's Order 636. However, the amount of costs that can ultimately be recovered is subject to approval by the FERC and market conditions. In December 1993, Apache Corporation (Apache) and Snyder Oil Corporation (Snyder) filed suit in North Dakota Northwest Judicial District Court (North Dakota District Court), against Williston Basin and the Company. Apache and Snyder are oil and natural gas producers which 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 as Williston Basin, the Company and Koch have settled their disputes. Apache and Snyder have recently provided alleged damages under differing theories ranging up to $4.8 million without interest. A motion to intervene in the case by several other producers, all of which had contracts with Koch but not with Williston Basin, was denied in December 1996. The trial before the North Dakota District Court was completed on November 6, 1997. Williston Basin and the Company are awaiting a decision from the North Dakota District Court. In a related matter, on March 14, 1997, a suit was filed by nine other producers, several of which had unsuccessfully tried to intervene in the Apache and Snyder litigation, against Koch, Williston Basin and the Company. The parties to this suit are making claims similar to those in the Apache and Snyder litigation, although no specific damages have been specified. In Williston Basin's opinion, the claims of Apache and Snyder are without merit and overstated and the claims of the nine other producers are without merit. If any amounts are ultimately found to be due, Williston Basin plans to file with the FERC for recovery from ratepayers. Regulatory Matters and Revenues Subject to Refund -- Williston Basin has pending with the FERC two general natural gas rate change applications implemented in 1992 and 1996. On October 20, 1997, Williston Basin appealed to the U.S. District Court of Appeals for the D.C. Circuit certain issues decided by the FERC in prior orders concerning the 1992 proceeding. On December 10, 1997, the FERC issued an order accepting, subject to certain conditions, Williston Basin's July 25, 1997 compliance filing. On December 22, 1997, Williston Basin submitted a compliance filing pursuant to the FERC's December 10, 1997 order. On December 31, 1997, Williston Basin refunded $33.8 million to its customers, including $30.8 million to Montana-Dakota, in addition to the $6.1 million interim refund that it had previously made in November 1996. All such amounts had been previously reserved. Williston Basin is awaiting an order from the FERC on its December 22, 1997 compliance filing. In June 1995, Williston Basin filed a general rate increase application with the FERC. As a result of FERC orders issued after Williston Basin's application was filed, in December 1995, Williston Basin filed revised base rates with the FERC resulting in an increase of $8.9 million or 19.1 percent over the currently effective rates. Williston Basin began collecting such increase effective January 1, 1996, subject to refund and is awaiting a final order from the FERC. Reserves have been provided for a portion of the revenues that have been collected subject to refund with respect to pending regulatory proceedings and to reflect future resolution of certain issues with the FERC. Williston Basin believes that such reserves are adequate based on its assessment of the ultimate outcome of the various proceedings. Natural Gas Repurchase Commitment -- The Company has offered for sale since 1984 the inventoried natural gas available under a repurchase commitment with Frontier Gas Storage Company, as described in Note 3 of Notes to Consolidated Financial Statements. As a part of the corporate realignment effected January 1, 1985, the Company agreed, pursuant to the settlement approved by the FERC, to remove from rates the financing costs associated with this natural gas. In January 1986, because of the uncertainty as to when a sale would be made, Williston Basin began charging the financing costs associated with this repurchase commitment to operations as incurred. Such costs, consisting principally of interest and related financing fees, approximated $5.7 million and $6.0 million in 1996 and 1995, respectively. The costs incurred in 1997 were not material and are included in "Other income -- net" on the Consolidated Statements of Income. 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 which in December 1996 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 as to the appropriate costs to be allocated. Williston Basin sells and transports natural gas held under the repurchase commitment. 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 43.0 MMdk of this gas to its then current 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. At December 31, 1997 and 1996, natural gas held under a repurchase commitment of $14.6 million and $37.2 million, respectively, is included in the Company's Consolidated Balance Sheets under "Deferred charges and other assets". The recognition of the then current market value of this natural gas facilitated the sale by Williston Basin of 28.1 MMdk from the date of this write-down through December 31, 1997, and should allow Williston Basin to market the remaining 14.9 MMdk on a sustained basis enabling Williston Basin to liquidate this asset over approximately the next three to four years. Capital Requirements -- The following schedule (in millions of dollars) summarizes the 1997 actual and 1998 through 2000 anticipated net capital expenditures, excluding potential acquisitions, applicable to Williston Basin's consolidated operations: Actual Estimated 1997 1998 1999 2000 Production and Gathering $ 4.8 $11.4 $14.2 $12.3 Underground Storage .3 .4 .3 .8 Transmission 3.6 3.2 11.4 4.6 General and Other 1.5 6.2 1.3 1.4 Energy Marketing .2 .3 .2 1.3 $10.4 $21.5 $27.4 $20.4 Environmental Matters -- Williston Basin's interstate natural gas transmission operations are generally subject to federal, state and local environmental, facility-siting, zoning and planning laws and regulations. Except as may be found with regard to the issues described below, Williston Basin believes it is in substantial compliance with those regulations. See "Environmental Matters" under "Montana-Dakota -- Retail Natural Gas and Propane Distribution" for a discussion of PCBs contained in Montana-Dakota's and Williston Basin's natural gas systems. CONSTRUCTION MATERIALS AND MINING OPERATIONS AND PROPERTY (KNIFE RIVER) Construction Materials Operations: General -- Knife River, through KRC Holdings, operates construction materials and mining businesses in the Anchorage, Alaska area, north and north-central California, southern Oregon and the Hawaiian Islands. These operations mine, process and sell construction aggregates (crushed rock, sand and gravel) and supply ready-mixed concrete for use in most types of construction, including homes, schools, shopping centers, office buildings and industrial parks as well as roads, freeways and bridges. In addition, the Alaskan, northern California and Oregon operations produce and sell asphalt for various commercial and roadway applications. Although not common to all locations, other products include the manufacture and/or sale of cement, various finished concrete products and other building materials and related construction services. On February 14, 1997, Baldwin Contracting Company, Inc. (Baldwin), a subsidiary of KRC Holdings, purchased the physical assets of Orland Asphalt located in Orland, California, including a hot-mix plant and aggregate reserves. Orland Asphalt was combined with and operates as part of Baldwin. On July 31, 1997, Knife River purchased the 50 percent interest in Hawaiian Cement, that it did not previously own, from Adelaide Brighton Cement (Hawaii), Inc. of Adelaide, Australia. The Company's initial 50 percent partnership interest in Hawaiian Cement was acquired in September 1995. On March 5, 1998, the Company acquired Morse Bros., Inc. and S2 - F Corp., privately-held construction materials companies located in Oregon's Willamette Valley. See Item 7 -- "Management's Discussion and Analysis of Financial Condition and Results of Operations" for more information regarding these acquisitions. Knife River's construction materials business has continued to grow since its first acquisition in 1992 and now comprises the majority of Knife River's business. Knife River continues to investigate the acquisition of other surface mining properties, particularly those relating to sand and gravel aggregates and related products such as ready-mixed concrete, asphalt and various finished aggregate products. For information regarding sales volumes and revenues for the construction materials operations for 1995 through 1997, see Item 7 -- "Management's Discussion and Analysis of Financial Condition and Results of Operations." Competition -- Knife River's construction materials products are marketed under highly competitive conditions. Since there are generally no measurable product differences in the market areas in which Knife River conducts its construction materials businesses, price is the principal competitive force these products are subject to, with service, delivery time and proximity to the customer also being significant factors. The number and size of competitors varies in each of Knife River's principal market areas and product lines. The demand for construction materials products is significantly influenced by the cyclical nature of the construction industry in general. The key economic factors affecting product demand are changes in the level of local, state and federal governmental spending, general economic conditions within the market area which influence both the commercial and private sectors, and prevailing interest rates. Knife River is not dependent on any single customer or group of customers for sales of its construction materials products, the loss of which would have a materially adverse affect on its construction materials businesses. During 1997, 1996 and 1995, no single customer accounted for more than 10 percent of annual construction materials revenues. Coal Operations: General -- Knife River is engaged in lignite coal mining operations. Knife River's surface mining operations are located at Beulah, North Dakota and Savage, Montana. The average annual production from the Beulah and Savage mines approximates 2.6 million and 300,000 tons, respectively. Reserve estimates related to these mine locations are discussed herein. During the last five years, Knife River mined and sold the following amounts of lignite coal: Years Ended December 31, 1997 1996 1995 1994 1993 (In thousands) Tons sold: Montana-Dakota generating stations 530 528 453 691 624 Jointly-owned generating stations -- Montana-Dakota's share 434 565 883 1,049 1,034 Others 1,303 1,695 2,767 3,358 3,299 Industrial and other sales 108 111 115 108 109 Total 2,375 2,899 4,218 5,206 5,066 Revenues $27,906 $32,696 $39,956 $45,634 $44,230 The decrease in total tons sold in 1997 compared to 1996, reflected in the above table, is the result of lower tons sold to the Coyote Station due to a ten-week maintenance outage. See Item 7 -- "Management's Discussion and Analysis of Financial Condition and Results of Operations" for more information regarding the sales volumes and revenues for the coal operations for 1995 through 1997. In recent years, in response to competitive pressures from other mines, Knife River has limited its coal price increases to less than those allowed under its contracts. Although Knife River has contracts in place specifying the selling price of coal, these price concessions are being made in an effort to remain competitive and maximize sales. Effective January 1, 1998, Montana-Dakota and Knife River agreed to a new five year coal contract for Montana-Dakota's Lewis & Clark generating station. In 1997, Knife River supplied approximately 180,000 tons of coal to this station. 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 have 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 that 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 the Co-owners are seeking damages in an unspecified amount. In January 1996, the Company and Knife River filed separate motions with the State District Court to dismiss or stay, pending arbitration. In May 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. In September 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. By order dated April 25, 1997, the arbitration panel concluded that the claims raised by the Co-owners are arbitrable. The Co-owners have 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, of 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. By letter dated May 14, 1997, Knife River requested permission to move for summary judgment which permission was granted by the arbitration panel over objections of the Co-owners. Knife River filed its summary judgment motion on July 21, 1997, which motion was denied on October 29, 1997. 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. Knife River does not anticipate any significant growth in its lignite coal operations in the near future due to competition from coal and other alternate fuel sources. Limited growth opportunities may be available to Knife River's lignite coal operations through the continued evaluation and pursuit of niche markets such as agricultural products processing facilities. Consolidated Construction Materials and Mining Operations: Capital Requirements -- The following schedule (in millions of dollars) summarizes the 1997 actual net capital expenditures, including those expended for the acquisitions of Orland Asphalt and the 50 percent interest in Hawaiian Cement that Knife River did not previously own, and 1998 through 2000 anticipated net capital expenditures, excluding potential acquisitions, applicable to Knife River's consolidated construction materials and mining operations: Actual Estimated 1997 1998 1999 2000 Construction Materials $38.0 $22.8 $10.2 $ 7.1 Coal 2.6 5.0 1.4 3.0 $40.6 $27.8 $11.6 $10.1 Environmental Matters -- Knife River's construction materials and mining operations are subject to regulation customary for surface mining operations, including federal, state and local environmental and reclamation regulations. Except as may be found with regard to the issue described below, Knife River believes it is in substantial compliance with those regulations. In September 1995, Unitek Environmental Services, Inc. and Unitek Solvent Services, Inc. (Unitek) filed a complaint against Hawaiian Cement in the U.S. 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 Clean Air Act, constituted a continual nuisance and trespass on the plaintiff's property, and that Hawaiian Cement's conduct warranted the award of punitive damages. Hawaiian Cement is a Hawaiian general partnership whose general partners are now Knife River Hawaii, Inc. and Knife River Dakota, Inc., indirect wholly owned subsidiaries of the Company. Knife River Dakota, Inc. purchased its partnership interest from Adelaide Brighton Cement (Hawaii), Inc. on July 31, 1997. Unitek sought civil penalties under the Clean Air Act (as described below), and up to $20 million in damages for various claims (as described above). In August 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. In September 1996, Unitek and Hawaiian Cement reached a settlement which resolved all claims except as to Clean Air Act penalties. 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 continued to negotiate the remaining Clean Air Act claims. In May 1996, the EPA issued a Notice of Violation (NOV) to Hawaiian Cement. The NOV stated 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. On April 7, 1997, a settlement resolving the remaining Clean Air Act claims and the EPA's NOV issued in May 1996, was reached by Hawaiian Cement, the EPA and Unitek. On February 11, 1998, the District Court approved the April 1997 settlement. The costs relating to both the September 1996 and April 1997 settlements were not material and did not affect the Company's results of operations since reserves had previously been provided. Reserve Information -- As of December 31, 1997, the combined construction materials operations had under ownership or lease approximately 169 million tons of recoverable aggregate reserves. As of December 31, 1997, Knife River had under ownership or lease, reserves of approximately 227 million tons of recoverable lignite coal, 87 million tons of which are at present mining locations. Such reserve estimates were prepared by Weir International Mining Consultants, independent mining engineers and geologists, in a report dated May 9, 1994, and have been adjusted for 1994 through 1997 production. Knife River estimates that approximately 64 million tons of its reserves will be needed to supply Montana-Dakota's Coyote, Heskett and Lewis & Clark stations for the expected lives of those stations and to fulfill the existing commitments of Knife River for sales to third parties. OIL AND NATURAL GAS OPERATIONS AND PROPERTY (FIDELITY OIL) General -- Fidelity Oil is involved in the acquisition, exploration, development and production of oil and natural gas properties. Fidelity Oil's operations vary from the acquisition of producing properties with potential development opportunities to exploratory drilling 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. Fidelity's oil and natural gas activities have continued to expand since the mid-1980's. Fidelity continues to seek additional reserve and production opportunities through the direct acquisition of producing properties and through exploratory drilling opportunities, as well as routine development of its existing properties. Future growth is dependent upon continuing success in these endeavors. Operating Information -- Information on Fidelity Oil's oil and natural gas production, average sales prices and production costs per net equivalent barrel related to its oil and natural gas interests for 1997, 1996 and 1995, are as follows: 1997 1996 1995 Oil: Production (000's of barrels) 2,088 2,149 1,973 Average sales price $17.50 $17.91 $15.07 Natural Gas: Production (MMcf) 13,192 14,067 12,319 Average sales price $2.41 $2.09 $1.51 Production costs, including taxes, per net equivalent barrel $3.65 $3.31 $3.18 Well and Acreage Information -- Fidelity Oil's gross and net productive well counts and gross and net developed and undeveloped acreage related to its interests at December 31, 1997, are as follows: Gross Net Productive Wells: Oil 2,279 138 Natural Gas 462 26 Total 2,741 164 Developed Acreage (000's) 614 56 Undeveloped Acreage (000's) 1,085 83 Exploratory and Development Wells -- The following table shows the results of oil and natural gas wells drilled and tested during 1997, 1996 and 1995: Net Exploratory Net Development Productive Dry Holes Total Productive Dry Holes Total Total 1997 1 2 3 3 1 4 7 1996 1 2 3 4 --- 4 7 1995 3 2 5 8 1 9 14 At December 31, 1997, there were six gross wells in the process of drilling, four of which were exploratory wells and two of which were development wells. Capital Requirements -- The following summary (in millions of dollars) reflects net capital expenditures, including those not subject to amortization, related to oil and natural gas activities for the years 1997, 1996 and 1995: 1997 1996 1995 Acquisitions $ --- $23.2 $ 9.1 Exploration 13.4 8.1 7.7 Development 15.4 15.9 22.2 $28.8 $47.2 $39.0 Fidelity Oil's net capital expenditures are anticipated to be approximately $50 million for 1998 and $60 million for both 1999 and 2000. Reserve Information -- Fidelity Oil's recoverable proved developed and undeveloped oil and natural gas reserves approximated 14.9 million barrels and 57.6 Bcf, respectively, at December 31, 1997. Of these amounts, 10.2 million barrels and 2.8 Bcf, as supported by a report dated January 12, 1998, prepared by Ralph E. Davis Associates, Inc., an independent firm of petroleum and natural gas engineers, were related to its properties located in southeastern Montana and southcentral Alabama. For additional information related to Fidelity Oil's oil and natural gas interests, see Note 18 of Notes to Consolidated Financial Statements. ITEM 3. LEGAL PROCEEDINGS Williston Basin -- Williston Basin has been named as a defendant in a legal action primarily related to certain natural gas price and volume issues. Such suit was filed by Moncrief. In addition, Williston Basin has been named as a defendant in a legal action related to a natural gas purchase contract. Such suit was filed by Apache and Snyder. In a related matter, Williston Basin has been named in a suit filed by nine other producers related to a natural gas purchase contract. The above legal actions are described under Items 1 and 2 -- "Business and Properties -- Natural Gas Transmission Operations and Property (Williston Basin)." The Company's assessment of the proceedings are included in the respective descriptions of the litigation. Knife River -- The Company and Knife River have been named as defendants in a legal action primarily related to coal pricing issues at the Coyote Station. The suit has been stayed by the State District Court pending arbitration. Such suit was filed by the Co-owners of the Coyote Station. Hawaiian Cement has been named as a defendant in a legal action primarily related to dust emissions from Hawaiian Cement's cement manufacturing plant at Kapolei, Hawaii. Such suit was filed by Unitek. In addition, the EPA has issued a NOV to Hawaiian Cement. On February 11, 1998, the District Court approved the April 1997 settlement which was reached by Hawaiian Cement, the EPA and Unitek. The above legal actions are described under Items 1 and 2 -- "Business and Properties -- Construction Materials and Mining Operations and Property (Knife River)." The Company's assessment of the proceedings is included in the respective descriptions of the litigation. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS No matters were submitted to a vote of security holders during the fourth quarter of 1997. PART II ITEM 5. MARKET FOR THE REGISTRANT'S COMMON STOCK AND RELATED STOCKHOLDER MATTERS The Company's common stock is listed on the New York Stock Exchange and the Pacific Stock Exchange under the symbol "MDU".

ITEM 6. SELECTED FINANCIAL DATA Reference is made to Selected Financial Data on pages 50 and 51 of the Company's Annual Report which is incorporated herein by reference. ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS For purposes of segment financial reporting and discussion of results of operations, Electric includes the electric operations of Montana-Dakota, as well as the operations of Utility Services. Natural Gas Distribution includes Montana-Dakota's natural gas distribution operations. Natural Gas Transmission includes Williston Basin's storage, transportation, gathering and natural gas production operations, and the energy marketing operations of its subsidiary, Prairielands. Construction Materials and Mining includes the results of Knife River's operations, while Oil and Natural Gas Production includes the operations of Fidelity Oil. Overview The following table (in millions of dollars) summarizes the contribution to consolidated earnings by each of the Company's businesses. Years ended December 31, Business 1997 1996 1995 Electric $ 13.4 $ 11.4 $ 12.0 Natural gas distribution 4.5 4.9 1.6 Natural gas transmission 11.3 2.5 8.4 Construction materials and mining 10.1 11.5 10.8 Oil and natural gas production 14.5 14.4 8.0 Earnings on common stock $ 53.8 $ 44.7 $ 40.8 Earnings per common share -- basic $ 1.86 $ 1.57 $ 1.43 Earnings per common share -- diluted $ 1.86 $ 1.57 $ 1.43 Return on average common equity 14.6% 13.0% 12.3% 1997 compared to 1996 Consolidated earnings for 1997 increased $9.1 million when compared to 1996. This increase includes the effect of the one-time adjustment in the third quarter of 1996 of $3.7 million or 13 cents per common share, reflecting the write-down to market value of natural gas being held under a repurchase commitment and certain reserve adjustments. The improvement is attributable to increased earnings from the natural gas transmission, electric and oil and natural gas production businesses, partially offset by a decrease in construction materials and mining and natural gas distribution earnings. 1996 compared to 1995 Consolidated earnings for 1996 were up $3.9 million when compared to 1995 including the effect of the $3.7 million net charge, previously described. The increase was the result of higher earnings at the oil and natural gas production, natural gas distribution and construction materials and mining businesses. Decreased earnings at the electric and natural gas transmission businesses somewhat offset the earnings improvement. ________________________________ Reference should be made to Items 1 and 2 -- "Business and Properties" and Notes to Consolidated Financial Statements for information pertinent to various commitments and contingencies.

Consolidated financial results are presented for 1997. In 1996 and 1995, Prairielands' financial results were included with the natural gas distribution business. ** Includes amortization and related recovery of deferred natural gas contract buy-out/ buy-down and gas supply realignment costs $ 5.5 $ 10.6 $ 11.4 Construction Materials and Mining Operations*** Years ended December 31, 1997 1996 1995 Operating revenues: Construction materials $ 146.2 $ 99.5 $ 73.1 Coal 27.9 32.7 39.9 174.1 132.2 113.0 Operating expenses: Operation and maintenance 145.6 105.8 87.8 Depreciation, depletion and amortization 11.0 7.0 6.2 Taxes, other than income 2.9 3.3 4.5 159.5 116.1 98.5 Operating income $ 14.6 $ 16.1 $ 14.5 Sales (000's): Aggregates (tons) 5,113 3,374 2,904 Asphalt (tons) 758 694 373 Ready-mixed concrete (cubic yards) 516 340 307 Coal (tons) 2,375 2,899 4,218 *** Prior to August 1, 1997, financial results did not include information related to Knife River's ownership interest in Hawaiian Cement, 50 percent of which was acquired in September 1995, and was accounted for under the equity method. On July 31, 1997, Knife River acquired the 50 percent interest in Hawaiian Cement that it did not previously own, and subsequent to that date financial results are consolidated into Knife River's financial statements. Oil and Natural Gas Production Operations Years ended December 31, 1997 1996 1995 Operating revenues: Oil $ 36.6 $ 39.0 $ 30.1 Natural gas 31.8 29.3 18.7 68.4 68.3 48.8 Operating expenses: Operation and maintenance 15.8 15.6 13.7 Depreciation, depletion and amortization 24.4 25.0 18.6 Taxes, other than income 3.9 3.5 2.6 44.1 44.1 34.9 Operating income $ 24.3 $ 24.2 $ 13.9 Production (000's): Oil (barrels) 2,088 2,149 1,973 Natural gas (Mcf) 13,192 14,067 12,319 Average sales price: Oil (per barrel) $ 17.50 $ 17.91 $ 15.07 Natural gas (per Mcf) 2.41 2.09 1.51 Amounts presented in the above tables for natural gas operating revenues, purchased natural gas sold and operation and maintenance expenses will not agree with the Consolidated Statements of Income due to the elimination of intercompany transactions between Montana- Dakota's natural gas distribution business and Williston Basin's natural gas transmission business. The amounts relating to the elimination of intercompany transactions for natural gas operating revenues, purchased natural gas sold and operation and maintenance expenses were $49.6 million, $48.0 million and $1.6 million, respectively, for 1997, $58.2 million, $53.8 million and $4.4 million, respectively, for 1996, and $54.6 million, $49.2 million and $5.4 million, respectively, for 1995. 1997 compared to 1996 Electric Operations Operating income at the electric business increased primarily due to increased retail sales and sales for resale revenues. Retail sales revenue increased due to increased rates in Wyoming reflecting recovery of costs associated with the new power supply contract with Black Hills Power and Light Company beginning January 1, 1997. Higher average realized rates in the remaining service territory and decreased net refunding due to timing of fuel costs to customers also added to the retail sales revenue improvement. Decreased weather-related sales primarily to residential customers in the fourth quarter somewhat offset the increase in retail sales revenue. Sales for resale revenue increased due to higher average realized rates caused by favorable market conditions in the third and fourth quarters. Increases in utility services revenue and related increases in operation and maintenance expense, depreciation, depletion, and amortization and taxes other than income resulted from International Line Builders, Inc. and High Line Equipment, Inc., which were acquired on July 1, 1997. Exclusive of the above- mentioned acquisitions, operation expenses decreased due to lower payroll and benefit-related expenses, which also added to the operating income improvement. Increased maintenance expense partially offset the increase in operating income. Power generation maintenance expense increased due to $1.9 million in costs resulting from a ten-week maintenance outage at the Coyote Station in 1997; this was somewhat offset by 1996 costs resulting from maintenance work at both the Lewis and Clark Station and the Big Stone Station. Higher transmission and distribution maintenance expense, due to the repair of damages associated with the April 1997 blizzard, also added to the increase in maintenance expense. Increased fuel and purchased power costs, largely resulting from increased purchase power demand charges and changes in generation mix, partially offset the operating income increase. The increase in demand charges is related to the power supply contract with Black Hills Power and Light Company. Earnings for the electric business improved due to the operating income increase but were slightly offset by increased interest expense due to higher average short-term debt balances. Earnings attributable to the electric services companies acquired on July 1, 1997, were $947,000. Natural Gas Distribution Operations Operating income decreased at the natural gas distribution business as a result of reduced sales of 3.9 million decatherms, the result of 15% warmer weather. The pass through of higher average gas costs more than offset the revenue decline that resulted from the reduced sales volumes. A general rate increase placed into effect in Montana in May 1996, which added to the revenue improvement, partially offset the operating income decline. Decreased operations expense due to lower payroll and benefit- related costs also partially offset the decrease in operating income. The effects of higher volumes transported, primarily to large industrial customers, were offset by lower average transportation rates. Natural gas distribution earnings declined largely due to the decrease in operating income. Decreased net interest expense and increased return on gas in storage and prepaid demand balances (included in Other income -- net) slightly offset the earnings decline. The decrease in net interest expense resulted from reduced carrying costs on natural gas costs refundable through rate adjustments due to lower refundable balances. Natural Gas Transmission Operations Operating income at the natural gas transmission business decreased primarily due to a decline in transportation revenues. Transportation revenues were lower due to the reversal of certain reserves for regulatory contingencies which added $4.2 million ($2.6 million after tax) to revenue in 1996. In addition, reduced recovery of deferred natural gas contract buy-out/buy-down and gas supply realignment costs and lower average transportation rates contributed to the decrease in transportation revenue. Transportation revenues also decreased due to additional reserved revenues provided, with a corresponding reduction in depreciation expense, as a result of FERC orders relating to a 1992 general rate proceeding. Increased volumes transported to off-system markets, due to sales of natural gas held under the repurchase commitment, were partially offset by lower on-system transportation, somewhat reducing the transportation revenue decline. Sales of natural gas held under the repurchase commitment were 17.9 MMdk, primarily volumes sold to off-system markets and volumes sold in place. Taxes other than income increased due primarily to increased property and production taxes which also contributed to the operating income decline. Natural gas production revenues for 1997, excluding the effect of intercompany eliminations of $5.6 million, improved as a result of both higher volumes produced and increased prices which partially offset the decrease in operating income. The increases in energy marketing revenue, purchased gas sold and the related increase in operation and maintenance expense resulted from Prairielands becoming a wholly owned subsidiary effective January 1, 1997. Operation expenses, excluding Prairielands, decreased due to reduced amortization of deferred natural gas contract buy-out/buy- down and gas supply realignment costs offset in part by higher royalties due to both a royalty settlement with the United States Minerals Management Service and increased production and prices. Earnings for this business increased due to the September 1996 $21.1 million ($12.9 million after tax) write-down of the natural gas available under the repurchase commitment to the then current market price. Gains realized on the sale of natural gas held under the repurchase commitment and decreased carrying costs on this gas stemming from lower average borrowings also added to the earnings increase. Increased income taxes due to the reversal of certain income tax reserves aggregating $4.8 million in September 1996 and decreased operating income both partially offset the earnings improvement. Construction Materials and Mining Operations Construction Materials Operations -- Construction materials operating income increased $3.3 million due to higher revenues primarily resulting from the acquisitions of Baldwin in April 1996, Medford Ready Mix, Inc. (Medford) in June 1996, Orland Asphalt in February 1997, and the 50% interest in Hawaiian Cement that Knife River did not previously own in July 1997. Revenues at other construction materials operations increased as a result of higher aggregate and ready-mixed concrete sales volumes, increased construction revenues, and higher asphalt prices. The increase in operation and maintenance and depreciation expenses was largely due to expenses associated with such acquisitions. Operation and maintenance expenses also increased at the other construction materials operations due to higher aggregate and ready- mixed concrete volumes sold. Coal Operations -- Operating income for the coal operations decreased $4.8 million, largely due to decreased revenues resulting from lower sales of 524,000 tons to the Coyote Station, the result of the ten-week maintenance outage. Higher average sales prices at the Beulah Mine partially offset the reduced coal revenues. Increased operation and maintenance expense due to higher stripping costs at the Beulah Mine, partially offset by lower volume-related costs and decreased taxes other than income, also added to the operating income decline. Consolidated -- Earnings declined due to decreased operating income at the coal business and decreased Other income -- net. The decrease in Other income -- net was due to the purchase of the 50% interest in Hawaiian Cement that Knife River did not previously own. Prior to August 1997, Knife River's original 50 percent ownership interest in Hawaiian Cement was accounted for under the equity method. However, on July 31, 1997, Knife River acquired the 50 percent interest in Hawaiian Cement that it did not previously own and Knife River in August 1997 began consolidating Hawaiian Cement into its financial statements. In addition, higher interest expense resulting mainly from increased long-term debt due to the aforementioned acquisitions also added to the decrease in earnings. Increased construction materials operating income and gains realized from the sale of equipment, partially offset the earnings decline. Oil and Natural Gas Production Operations Operating income for the oil and natural gas production business at Fidelity Oil increased slightly as a result of higher natural gas revenues. The increase in natural gas revenue resulted from a $4.6 million improvement due to higher average prices somewhat offset by a $2.1 million decrease due to lower production. Decreased oil revenue largely offset the natural gas revenue increase. The decline in oil revenue was due to a $1.3 million decrease resulting from lower average oil prices and a $1.1 million decline due to lower production. Decreased depreciation, depletion and amortization, largely the result of lower production, also added to the increase in operating income. Increased taxes other than income partially offset the increase in operating income. Earnings for this business unit increased due to the operating income improvement and decreased interest expense due to lower average long-term debt balances. Increased income taxes somewhat offset the earnings improvement. The increase in income taxes resulted from the reversal of certain tax reserves aggregating $1.8 million in September 1996 somewhat offset by higher tax credits in 1997. 1996 compared to 1995 Electric Operations Operating income at the electric business decreased primarily due to increased fuel and purchased power costs, resulting primarily from both higher purchased power demand charges and increased net sales. The increase in demand charges, related to a participation power contract, was the result of the pass-through of periodic maintenance costs as well as the purchase of an additional five megawatts of capacity beginning in May 1996, which brought the total level of capacity available under this contract to 66 megawatts. Also contributing to the operating income decline were higher operation expenses, primarily resulting from higher transmission and payroll-related costs due to establishing certain contingency reserves, and higher depreciation expense, due to an increase in average depreciable plant. Increased revenues, primarily higher retail sales due to increased weather-related demand from residential and commercial customers in the first and fourth quarters of 1996, largely offset the operating income decline. Lower sales for resale volumes due to line capacity restrictions within the regional power pool were more than offset by higher average realized rates also partially offsetting the operating revenue increase. Earnings for the electric business decreased due to the operating income decline, and decreased service and repair income and lower investment income, both included in Other income -- net. Natural Gas Distribution Operations Operating income at the natural gas distribution business improved largely as a result of increased sales revenue. The sales revenue improvement resulted primarily from a 3.6 million decatherm increase in volumes sold due to 14% colder weather and increased sales resulting from the addition of over 3,600 customers. Also contributing to the sales revenue improvement were the effects of a general rate increase placed into effect in Montana in May 1996. However, the pass-through of lower average natural gas costs partially offset the sales revenue improvement. Decreased operations expense due to lower payroll-related costs also added to the operating income improvement. Lower transportation revenues, primarily decreased volumes transported to large industrial customers, somewhat offset the operating income improvement. Industrial transportation declined due to lower volumes transported to two agricultural processing facilities, one of which closed in September 1995, and one of which experienced lower production, and to a cement manufacturing facility due to its use of an alternate fuel. Natural gas distribution earnings increased due to the operating income improvement, decreased interest expense and higher service and repair income. The decline in interest expense resulted from lower average long-term debt and natural gas costs refundable through rate adjustment balances. Natural Gas Transmission Operations Operating income at the natural gas transmission business increased primarily due to an improvement in transportation revenues resulting from increased transportation of natural gas held under the repurchase commitment, increased volumes transported to storage and the reversal of certain reserves for regulatory contingencies of $3.9 million ($2.4 million after tax). The benefits derived from a favorable rate change implemented in January 1996, also added to the revenue improvement. The nonrecurring effect of a favorable FERC order received in April 1995, on a rehearing request relating to a 1989 general rate proceeding partially offset the transportation revenue improvement. The order allowed for the one-time billing of customers for approximately $2.7 million ($1.7 million after tax) to recover a portion of the amount previously refunded in July 1994. In addition, reduced recovery of deferred natural gas contract buy- out/buy-down and gas supply realignment costs partially offset the increase in transportation revenue. An increase in natural gas production revenue, due to both higher volumes and prices, also contributed to the operating income improvement. Decreased storage revenues, due primarily to the implementation of lower rates in January 1996, partially offset the increase in operating income. Operation expenses increased primarily due to higher payroll-related costs and production royalties but were slightly offset by reduced amortization of deferred natural gas contract buy-out/buy-down costs. Earnings for this business decreased due to the write-down to the then current market price of the natural gas available under the repurchase commitment. The effect of the write-down, which was $21.1 million, or $12.9 million after tax, was significantly offset by the reversal of certain income tax reserves aggregating $4.8 million. Decreased interest income, largely related to $583,000 (after tax) of interest on the previously discussed 1995 refund recovery combined with higher company production refunds (both included in Other income -- net), also added to the earnings decline. Increased net interest expense ($366,000 after tax), largely resulting from higher average reserved revenue balances partially offset by decreased long-term debt expense due to lower average borrowings, further reduced earnings. The earnings decrease was somewhat offset by the increase in operating income. Construction Materials and Mining Operations Construction Materials Operations -- Construction materials operating income increased $3.3 million due to higher revenues. The revenue improvement is largely due to revenues realized as a result of the Baldwin and Medford acquisitions. Revenues at most other construction materials operations decreased as a result of lower aggregate and asphalt sales due to lower demand, and lower construction sales due to the nature of work being performed this year as compared to last year, offset in part by increased building materials sales and aggregate and ready-mixed concrete prices. Operation and maintenance expenses increased due to the above acquisitions but were somewhat offset by a reduction at other construction materials operations resulting from lower volumes sold and less work involving the use of subcontractors. Coal Operations -- Operating income for coal operations decreased $1.7 million primarily due to decreased revenues, largely the result of the expiration of the coal contract with the Big Stone Station in August 1995, and the resulting closure of the Gascoyne Mine. Higher average sales prices due to price increases at the Beulah Mine partially offset the decreased coal revenues. Decreased operation and maintenance expenses, depreciation expense and taxes other than income, largely due to the mine closure, partially offset the decline in operating income. Consolidated -- Earnings increased due to the increase in construction materials operating income and income from a 50 percent interest in Hawaiian Cement acquired in September 1995 of $1.7 million as compared to $1.0 million in 1995 (included in Other income -- net). Higher interest expense ($1.4 million after tax), resulting mainly from increased long-term debt due to the acquisition of Hawaiian Cement, Baldwin and Medford, and the decline in coal operating income somewhat offset the increase in earnings. Oil and Natural Gas Production Operations Operating income for the oil and natural gas production business increased primarily as a result of higher oil and natural gas revenues. Higher oil revenue resulted from a $5.6 million increase due to higher average prices and a $3.2 million increase due to improved production. The increase in natural gas revenue was due to a $7.0 million increase arising from higher prices and a $3.6 million improvement resulting from higher production. Increased operation and maintenance expenses, largely due to higher production, and higher taxes other than income, primarily the result of higher prices, both partially offset the operating income improvement. Also reducing operating income was increased depreciation, depletion and amortization expense resulting from increased average rates and higher production. Depreciation, depletion and amortization rates increased in part due to the accrual of estimated future well abandonment costs ($515,000 after tax). Earnings for this business unit increased due to the operating income improvement and lower income taxes due to the reversal of certain tax reserves aggregating $1.8 million. Increased interest expense ($815,000 after tax), resulting mainly from higher average borrowings, and lower tax benefits somewhat offset the earnings improvement. Safe Harbor for Forward-Looking Statements The Company is including the following cautionary statement in this Form 10-K to make applicable and to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 for any forward-looking statements made by, or on behalf of, the Company. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions (many of which are based, in turn, upon further assumptions) and other statements which are other than statements of historical facts.

All such subsequent forward-looking statements, whether written or oral and whether made by or on behalf of the Company, are also expressly qualified by these cautionary statements. Forward-looking statements involve risks and uncertainties which could cause actual results or outcomes to differ materially from those expressed. The Company's expectations, beliefs and projections are expressed in good faith and are believed by the Company to have a reasonable basis, including without limitation management's examination of historical operating trends, data contained in the Company's records and other data available from third parties, but there can be no assurance that the Company's expectations, beliefs or projections will be achieved or accomplished. Furthermore, any forward-looking statement speaks only as of the date on which such statement is made, and the Company undertakes no obligation to update any forward-looking statement or statements to reflect events or circumstances that occur after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for management to predict all of such factors, nor can it assess the effect of each such factor on the Company's business or the extent to which any such factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement. Regulated Operations -- In addition to other factors and matters discussed elsewhere herein, some important factors that could cause actual results or outcomes for the Company and its regulated operations to differ materially from those discussed in forward-looking statements include prevailing governmental policies and regulatory actions with respect to allowed rates of return, financings, or industry and rate structures, weather conditions, acquisition and disposal of assets or facilities, operation and construction of plant facilities, recovery of purchased power and purchased gas costs, present or prospective generation, wholesale and retail competition (including but not limited to electric retail wheeling and transmission costs), availability of economic supplies of natural gas, and present or prospective natural gas distribution or transmission competition (including but not limited to prices of alternate fuels and system deliverability costs). Non-Regulated Operations -- Certain important factors which could cause actual results or outcomes for the Company and all or certain of its non-regulated operations to differ materially from those discussed in forward- looking statements include the level of governmental expenditures on public projects and project schedules, changes in anticipated tourism levels, competition from other suppliers, oil and natural gas commodity prices, drilling successes in oil and natural gas operations, ability to acquire oil and natural gas properties, and the availability of economic expansion or development opportunities. Factors Common to Regulated and Non-Regulated Operations -- The business and profitability of the Company are also influenced by economic and geographic factors, including political and economic risks, changes in and compliance with environmental and safety laws and policies, weather conditions, population growth rates and demographic patterns, market demand for energy from plants or facilities, changes in tax rates or policies, unanticipated project delays or changes in project costs, unanticipated changes in operating expenses or capital expenditures, labor negotiations or disputes, changes in credit ratings or capital market conditions, inflation rates, inability of the various counterparties to meet their obligations with respect to the Company's financial instruments, changes in accounting principles and/or the application of such principles to the Company, changes in technology and legal proceedings, and compliance with the year 2000 issue as discussed later. Year 2000 Compliance The year 2000 issue is the result of computer programs having been written using two digits rather than four digits to define the applicable year. The Company has recently completed an assessment of its operations to determine the costs expected to be incurred specifically related to modifications necessary for year 2000 compatibility. While the Company will continue to evaluate the potential effects of the year 2000 issue, based on its recent assessment, the Company believes that these costs will not be material to its results of operations. The Company's operations with respect to the year 2000 issue may also be affected by other entities with which the Company transacts business. The Company is currently unable to determine the potential adverse consequences, if any, that could result from such entities' failure to effectively address this issue. Liquidity and Capital Commitments The Company's net capital expenditures (in millions of dollars) for 1995 through 1997 and as anticipated for 1998 through 2000 are summarized in the following table, which also includes the Company's capital needs for the retirement of maturing long-term securities. Actual Estimated* 1995 1996 1997 Capital Expenditures -- 1998 1999 2000 Montana-Dakota: $ 19.7 $ 18.7 $ 18.4 Electric $ 17.0 $ 15.9 $ 17.0 8.9 6.3 8.8 Natural Gas Distribution 7.9 9.4 7.5 28.6 25.0 27.2 24.9 25.3 24.5 12.3 10.9 11.4 Williston Basin 21.4 26.9 20.0 36.8 25.0 41.5 Knife River 27.8 11.6 10.1 39.9 51.8 30.6 Fidelity 50.0 62.0 62.0 --- --- 11.4 Other 2.8 1.1 1.1 117.6 112.7 122.1 126.9 126.9 117.7 Net proceeds from sale or (2.8) (11.8) (4.5) disposition of property .5 (1.5) (1.6) 114.8 100.9 117.6 Net capital expenditures 127.4 125.4 116.1 Retirement of Long-term Debt/Preferred Stock -- 10.4 35.4 42.4 Montana-Dakota 5.4 5.4 5.4 10.1 8.0 .5 Williston Basin .5 .5 .8 --- --- --- Knife River 1.3 1.3 36.8 --- --- 4.8 Fidelity --- 7.9 10.8 --- --- .3 Other .7 .2 .1 20.5 43.4 48.0 7.9 15.3 53.9 $135.3 $144.3 $165.6 Total $135.3 $140.7 $170.0 * The anticipated 1998 through 2000 net capital expenditures reflected in the above table do not include potential acquisitions. To the extent that acquisitions occur, such acquisitions would be financed with existing credit facilities and the issuance of long-term debt and the Company's equity securities. In reconciling total net capital expenditures to investing activities per the Consolidated Statements of Cash Flows, the net capital expenditures for Prairielands of $800,000 and $2.6 million in 1996 and 1995, respectively, included with Williston Basin above and not considered a major business segment, are not reflected in investing activities in the Consolidated Statements of Cash Flows. In addition, the total 1997 net capital expenditures, related to acquisitions, in the above table include assumed debt and the issuance of the Company's equity securities, which were $9.9 million in total. In 1997 Montana-Dakota provided all the funds needed for its net capital expenditures and securities retirements, excluding the $20 million discussed below, from internal sources. Net capital expenditures for the years 1998 through 2000 include those for system upgrades, routine replacements and service extensions. Montana-Dakota expects to provide all of the funds required for these net capital expenditures and securities retirements for the years 1998 through 2000 from internal sources, through the use of the Company's $40 million revolving credit and term loan agreement, $18 million of which was outstanding at December 31, 1997, and through the issuance of long-term debt, the amount and timing of which will depend upon the Company's needs, internal cash generation and market conditions. In October 1997, the Company redeemed $20 million of its 9 1/8% Series first mortgage bonds, due October 1, 2016. The funds required to retire the 9 1/8% Series first mortgage bonds were provided by the issuance of $30 million in Secured Medium-Term Notes on September 30, 1997. In addition, in November 1997, the Company redeemed $5 million of its 9 1/8% Series first mortgage bonds, due May 15, 2006. On December 19, 1997, amounts available under the revolving credit and term loan agreement increased from $30 million to $40 million. Williston Basin's 1997 net capital expenditures and securities retirements were met through internally generated funds. Williston Basin's net capital expenditures for the years 1998 through 2000, excluding potential acquisitions, include those for pipeline expansion projects, routine system improvements and continued development of natural gas reserves. These expenditures are expected to be met with a combination of internally generated funds, short-term lines of credit aggregating $40.6 million, $350,000 of which was outstanding at December 31, 1997, and through the issuance of long-term debt, the amount and timing of which will depend upon Williston Basin's needs, internal cash generation and market conditions. Knife River's 1997 net capital expenditures including the acquisitions of Orland Asphalt and the 50 percent interest in Hawaiian Cement that it did not previously own were met through funds generated from internal sources and a revolving credit agreement. Knife River's 1998 through 2000 net capital expenditures, excluding potential acquisitions, include routine equipment rebuilding and replacement and the construction of aggregate materials handling facilities. It is anticipated that funds generated from internal sources, short-term lines of credit aggregating $26 million, $2 million of which was outstanding at December 31, 1997, a revolving credit agreement of $85 million, $33 million of which was outstanding at December 31, 1997, and the issuance of long-term debt and the Company's equity securities will meet the needs of this business unit for 1998 through 2000. In June 1997, amounts available under the revolving credit agreement were increased from $55 million to $85 million. In addition, in July 1997, amounts available under the short-term lines of credit increased from $11 million to $26 million. In November 1997, Knife River privately placed $35 million of notes with the proceeds used to replace other long-term debt. Fidelity Oil's 1997 net capital expenditures related to its oil and natural gas acquisition, development and exploration program were met through funds generated from internal sources. Fidelity's borrowing base, which is based on total proved reserves, is currently $65 million. This consists of $20 million of issued notes, $10 million in an uncommitted note shelf facility, and a $35 million revolving line of credit, $13 million of which was outstanding at December 31, 1997. It is anticipated that Fidelity's 1998 through 2000 net capital expenditures and debt retirements will be met from internal sources and existing long-term credit facilities. Fidelity's net capital expenditures for 1998 through 2000 will be used to further enhance production and reserve growth. Other corporate 1997 net capital expenditures, largely those expended for the acquisitions of International Line Builders, Inc. and High Line Equipment, Inc., were met through short-term lines of credit and the issuance of long-term debt and the Company's equity securities. It is anticipated that 1998 through 2000 other net capital expenditures, excluding potential acquisitions, used for routine equipment maintenance and replacements will be met from internal sources and existing short-term lines of credit aggregating $3.8 million, $997,000 of which was outstanding at December 31, 1997. The Company utilizes its short-term lines of credit aggregating $50 million, none of which was outstanding on December 31, 1997, and its $40 million revolving credit and term loan agreement, $18 million of which was outstanding at December 31, 1997, as previously described, to meet its short-term financing needs and to take advantage of market conditions when timing the placement of long- term or permanent financing. On July 31, 1997, amounts available under the short-term lines of credit were increased from $40 million to $50 million. The Company's issuance of first mortgage debt is subject to certain restrictions imposed under the terms and conditions of its Indenture of Mortgage. Generally, those restrictions require the Company to pledge $1.43 of unfunded property to the Trustee for each dollar of indebtedness incurred under the Indenture and that annual earnings (pretax and before interest charges), as defined in the Indenture, equal at least two times its annualized first mortgage bond interest costs. Under the more restrictive of the two tests, as of December 31, 1997, the Company could have issued approximately $259 million of additional first mortgage bonds. The Company's coverage of fixed charges including preferred dividends was 3.4 and 2.7 times for 1997 and 1996, respectively. Additionally, the Company's first mortgage bond interest coverage was 6.0 times in 1997 compared to 5.4 times in 1996. Common stockholders' equity as a percent of total capitalization was 55 percent and 54 percent at December 31, 1997 and 1996, respectively. Recent Development On March 5, 1998, the Company acquired Morse Bros., Inc. (MBI), and S2 - F Corp. (S2-F), privately-held construction materials companies located in Oregon's Willamette Valley. The purchase consideration for such companies consisted of approximately $96 million of the Company's common stock and cash, the assumption of certain liabilities and an adjustment based on working capital. The common stock of the Company, issued in exchange for all of the issued and outstanding stock of MBI and S2-F was unregistered and is subject to certain restrictions. The acquisition will be accounted for under the purchase method of accounting. Under this method, the consideration for the stock of MBI and S2-F will be allocated to the underlying assets acquired and liabilities assumed, based on their estimated fair market values. The Company anticipates that the effect of such acquisitions will be accretive to earnings. Financial statements of the acquired companies and proforma financial statements have not been presented as such information is not required in accordance with the rules and regulations of the Securities and Exchange Commission. MBI, the largest construction materials supplier in Oregon, sells aggregate, ready-mixed concrete, asphaltic concrete, prestress concrete and construction services in the Willamette Valley from Portland to Eugene. The products of MBI are used in the construction of streets, roads, and highways and in both building and bridge structures. Assets owned by MBI include aggregate reserves and construction materials plant and equipment. S2-F sells aggregate and construction services and their properties consist primarily of construction and aggregate mining equipment and leased aggregate reserves. In 1997, MBI and S2-F had combined net sales of $107 million and have approximately 370 million tons of aggregate reserves, of which 270 million tons are permitted. It is the intent of the Company that MBI and S2-F continue their operations and businesses. Effects of Inflation Inflation did not have a significant effect on the Company's operations in 1997, 1996 or 1995. ITEM 7A.
