Management's Discussion and Analysis Northwestern Public Service is a diversified energy distribution company with core operations engaged in the propane, electric and natural gas industries. Northwestern generates and distributes electric energy to 56,000 customers in eastern South Dakota and purchases and distributes natural gas to 77,000 customers in eastern South Dakota and four communities in Nebraska. The Company acquired Synergy Group Incorporated, a major retail propane distributor in August 1995. In 1996, Northwestern acquired eight additional propane companies, including Empire Energy Corporation in October, then the eighth largest retail marketer of propane in the U.S., and CGI Holdings, Inc., then the eighteenth largest retail marketer of propane in the U.S. in December. Also in December 1996, Northwestern combined all of its propane businesses into Cornerstone Propane Partners, L.P., (Cornerstone) a publicly traded master limited partnership which sold 9.8 million common units to the public on December 17, 1996, at a price of $21 per unit. Net proceeds from the offering of common units, together with the concurrent sale of $220 million of senior secured notes by a subsidiary partnership, were used to redeem preferred stock of the combined propane entities and repay acquisition loans and existing debt. Northwestern's majority-owned subsidiaries hold 6.9 million subordinated units or 41.4% of Cornerstone, while public unitholders, own 58.6% of the Partnership. Cornerstone is the fifth largest retail propane marketer in the U.S., serving approximately 360,000 customers from 312 service centers in 26 states. Weather - ------- Weather patterns have a significant impact on the Company's operating performance. Because propane and natural gas are heavily used for residential and commercial heating, the demand for these products depends upon weather patterns throughout the Company's market areas. With a larger proportion of its operations related to seasonal propane and natural gas sales in 1997, the distribution of the Company's quarterly operating performance will be different than in historical periods. A greater portion of the Company's future operating income is expected to be recognized in the first and fourth quarters related to higher revenues from the winter heating season. Earnings - -------- Earnings for 1996 were $22.9 million or $2.56 per share, compared to $18.0 million or $2.21 per share for 1995. Earnings per share for 1996 included $.19 related to a one-time gain from proceeds received related to the Cornerstone refinancing transactions. Earnings from ongoing operations were $2.37 per share, up 7.2% from $2.21 per share in 1995. The earnings increase was primarily due to slightly colder weather, propane acquisitions, improved natural gas returns and increased investment income. Earnings per share in 1995 were $2.21 compared to $2.00 in 1994. The increase was primarily due to greater electric retail sales, modest gas rate relief, and increased contributions from nonregulated businesses, principally propane. Earnings for 1995 included propane operations since August 1995. Dividends - --------- In November 1995, the Company's Board of Directors elected to increase annual dividends per share from $1.70 to $1.76. Subsequently, in November 1996, the Board approved an eight cent per share increase in annual dividends from $1.76 to $1.84. The Company's financial strength, operating performance, the success of its growth strategies and competitive changes in the industry will be factors considered by the Company's Board of Directors when evaluating future dividend payments. - ------------------------- Business Segment Summary - ------------------------- Year Ended Increase Increase December 31 1996 1995 (Decrease) 1994 (Decrease) (thousands of dollars) -------- ------- --------------- -------- ------------ REVENUES Propane $175,102 $38,883 $136,219 350.3% - $38,883 - Electric 73,417 74,857 (1,440) (1.9%) $73,077 1,780 2.4% Natural Gas 72,269 64,483 7,786 12.1% 62,141 2,342 3.8% Manufacturing 23,221 26,747 (3,526)(13.2%) 22,047 4,700 21.3% OPERATING INCOME Propane $ 18,947 $ 5,604 $ 13,343 238.1% - $ 5,604 - Electric 24,475 26,003 (1,528) (5.9%) $25,662 341 1.3% Natural Gas 5,684 3,862 1,822 47.2% 2,540 1,322 52.0% Manufacturing 1,312 2,628 (1,316)(50.1%) 2,334 294 12.6% OPERATING DATA Propane sales- (000 gallons) 160,005 37,805 122,200 323.2% - 37,805 - Electric sales-retail (000 mwh) 1,083 1,071 12 1.1% 1,019 52 5.1% Natural Gas throughput (000 mmbtu) 16,321 15,204 1,117 7.3% 14,750 454 3.1% - --------------------- Results of Operations - --------------------- PROPANE (graph of information in following table) Revenue Growth (000's) Propane Electric Natural Gas Manufacturing -------- --------- ----------- ------------- 1994 - 73,077 62,141 22,047 1995 38,883 74,858 64,483 26,747 1996 175,102 73,417 72,269 23,221 (end of graph) Propane operations include revenues from Cornerstone since December 18, 1996, Empire Energy Corporation since October 7, 1996, and Synergy Group Incorporated for all of 1996. Weather throughout Synergy's propane service area was about 5% colder than normal while weather throughout Empire Energy's area was about 3% colder than normal since acquisition. Because of the heavy use of propane for heating, propane sales are extremely weather sensitive. The majority of propane revenues occur in the first and fourth quarters when propane is heavily sold for residential and commercial heating. Operating revenue from propane sales increased in 1996 to $175.1 from $38.9 million in 1995. Operating income increased in 1996 to $18.9 million from $5.6 million in 1995. The large increases in sales and operating income are primarily due to a full year of operations for Synergy which was acquired in August 1995, the acquisition of Empire Energy in October 1996 and the formation of Cornerstone in December 1996. The increases are also partly due to slightly colder than normal weather in the Company's propane market areas. In accordance with the Company's plans, substantial changes are being made in the management and operation of the acquired propane businesses in order to achieve improvement in the results of operations. Among the cost efficiency measures being put into place to reduce operating, selling and administrative expenses is the consolidation of corporate functions of all the acquired propane businesses. ELECTRIC (graph of information in following table) Electric Retail Sales (000 kwh) ------------------------------- 1994 1,018,509 1995 1,071,328 1996 1,082,704 (end of graph) In 1996, retail electric mwh sales grew by 1% even though weather during the summer was approximately 20% cooler than the previous year. Electric revenues decreased slightly due to a decline in wholesale sales. Operating income decreased due to the slight decrease in revenues combined with increases in growth-related costs in expanded energy services, marketing functions and property taxes. Property taxes increased significantly in 1996 due primarily to changes in South Dakota's tax regulations. 1995 vs. 1994. In 1995, revenue increases were related to a 5.1% increase in retail kwh sales over 1994. In 1995, the Company set a new record for peak electric demand during the summer exceeding the previous peak record set in 1991 by 8%. The increase in electric operating income reflects the higher retail sales, offset by slightly higher operating expenses. Maintenance expense declined slightly while depreciation and property taxes reflect the increase in depreciable plant. NATURAL GAS (graph of information in following table) Gas Throughput 000 mmbtu ---------------------------- 1994 14,750 1995 15,204 1996 16,321 (end of graph) One of the predominant factors affecting the Company's natural gas operations is weather patterns during the winter heating season. Because natural gas is heavily used for residential and commercial heating, the demand for this product depends upon weather conditions. In 1996, the increase in natural gas revenues over 1995 reflects the effects of cooler weather, higher market prices for natural gas supply which are passed on to customers through the purchased gas adjustment mechanism and a slight increase in customers. The increase in gas operating income reflects a 7.3% increase in throughput, offset by slightly higher operating expenses. The increase in other operating expenses was primarily due to growth-related costs in the expanded energy services and marketing functions. Maintenance expense decreased slightly while property taxes increased due to changes in South Dakota tax regulations. 1995 vs. 1994. Cooler weather patterns during the heating season resulted in a 3.8% increase in gas revenues. Natural gas revenues include an overall rate increase in South Dakota implemented on November 15, 1994, and an overall increase in Nebraska effective April 1, 1995. The increase in operating income was related to a 3.1% increase in throughput and effects of rate increases, offset by slightly higher operating expenses. Maintenance expense declined slightly while depreciation and property taxes reflect the increase in depreciable plant. MANUFACTURING Manufacturing revenues and operating income are related to the Company's ownership interest in Lucht Inc., a company that manufactures photographic processing and imaging equipment used by high-volume photo processing laboratories. Operating income in 1996 decreased when compared to 1995 due to decreased sales resulting from manufacturing delays in product development. Operating income in 1995 increased by 12.6% over 1994 due to acquisitions and an increase in sales of existing product lines. OTHER INCOME STATEMENT ITEMS Other income increased in 1996 over 1995 primarily due to a one-time gain realized by the Company related to the Cornerstone transaction. The gain is attributed to various prepayment and redemption premiums realized when propane assets and liabilities were contributed to Cornerstone. Other income also includes the gain on the sale of a portion of a common stock investment. - ------------------------------- Liquidity and Capital Resources - ------------------------------- During 1996, cash flow from operations, net of dividends paid, together with proceeds from the Cornerstone equity and debt offerings and other external financing activities, provided the funds for propane and other acquisition activities, construction expenditures and other requirements. Operating Activities - -------------------- (graph of information in following table) Cash Flows From Operating Activities ------------------------- 1994 26,268,921 1995 35,366,960 1996 60,903,017 (end of graph) Cash flow from operating activities in 1996 increased 66% from 1995 primarily due to propane acquisitions and growth in the Company's earnings. Liquidity is also provided from the availability of substantial cash and investment balances. Cash equivalents and marketable securities totaled $179.9 million, $44.7 million and $39.2 million at December 31, 1996, 1995 and 1994. Investment Activities - Financing Activities - --------------------------------------------- The Company's principal investments and capital requirements in 1996 were related to the acquisition of retail propane distributors Empire Energy Corporation and CGI Holdings, Inc. which were refinanced by the Cornerstone equity and debt offerings. The Cornerstone partnership sold 9.8 million common units to the public with net proceeds of approximately $192 million and also issued, in conjunction with the partnership public offering, $220 million of nonrecourse 7.53% series senior mortgage notes maturing in 2010 with eight equal annual installments beginning in the year 2003. Working capital and other financial resources are also provided by unused lines of credit which are generally used to support commercial paper borrowings, a primary source of short-term financing. At December 31, 1996, the Company had no outstanding borrowings under its lines of credit or commercial paper borrowings. Unused short-term lines of credit totaled $24 million at December 31, 1996. In addition, the Company's nonregulated businesses maintain credit agreements with various banks for revolving and term loans. The Company will continue to review the economics of retiring or refunding long-term debt and preferred stock to minimize long-term financing costs. The Company's financial coverages are at levels in excess of those required for the issuance of additional debt and preferred stock. - -------------------- Capital Requirements - -------------------- The Company's primary capital requirements include the funding of its energy business construction and expansion programs, the funding of debt and preferred stock retirements, sinking fund requirements and the funding of its corporate development and investment activities. The emphasis of the Company's construction activities is to undertake those projects that most efficiently serve the expanding needs of its customer base, enhance energy delivery and reliability capabilities through system replacement and provide for the reliability of energy supply. Capital expenditure plans are subject to continual review and may be revised as a result of changing economic conditions, variations in sales, environmental requirements, investment opportunities and other ongoing considerations. Expenditures for construction activities for 1996, 1995 and 1994 were $35.2 million, $29.6 million and $22.7 million. Construction expenditures during the last three years included expenditures related to an operations center expected to provide enhanced customer service capability, cost savings and operating efficiencies through consolidation of activities and the expansion of the Company's natural gas system in eastern South Dakota. In addition, 1996 and 1995 included $9.8 million and $4.7 million of capital expenditures related to propane operations. Total expenditures for 1997, excluding propane operations, are estimated to be $14.5 million. The majority of the projected expenditures will be spent on enhancements of the electric and gas distribution systems. Estimated electric and natural gas related construction expenditures for the years 1997 through 2001 are expected to be $69.1 million. Nonregulated maintenance capital expenditures for 1997 are estimated to be $4.8 million. Estimated nonregulated maintenance capital expenditures for the years 1997 through 2001 are expected to be $18.8 million. Capital requirements for the mandatory retirement of long-term debt and mandatory preferred stock sinking fund redemption totaled $400,000, $600,000, and $600,000 for the years ended 1996, 1995 and 1994, respectively. It is expected that such mandatory retirements will be $1.2 million in 1997, $21.5 million in 1998, $14.0 million in 1999, $6.5 million in 2000 and $6.5 million in 2001. The Company anticipates that future capital requirements will be met by existing investments and marketable securities, internally generated cash flows and available external financing. - ----------------------------- Competition and Business Risk - ----------------------------- The electric and natural gas industries continue to undergo numerous transformations, and the Company is operating in an increasingly competitive marketplace. The passage of the National Energy Policy Act of 1992 has accelerated competition in the electric business by promoting competition in the industry at the wholesale level. Competition in the Company's gas business was accelerated with the passage of the Federal Energy Regulatory Commission's (FERC) Order 636 which resulted in an unbundling of gas supply and services to customers, or separately-priced sale and transportation services. The changes in the electric business are expected to be similar to those experienced in the natural gas business over the last few years. The FERC, which regulates interstate and wholesale electric transactions, has opened up transmission grids and mandated that utilities must allow others equal access to utility transmission systems. Various state regulatory bodies are also supporting initiatives to redefine the electric energy market and are experimenting with retail wheeling which gives some retail customers the ability to choose their supplier of electricity. Traditionally, utilities have been vertically integrated, providing bundled energy services to customers. The potential for continued unbundling of energy services exists, allowing customers to buy their own electricity and natural gas on the open market and having it delivered by the local utility. The growing pace of competition in the energy industry has been a primary focus of management over the last few years. The Company's future financial performance will be dependent on the effective execution of operating strategies to address a more competitive and changing energy marketplace. Business strategies focus on enhancing the Company's competitive position, on expanding energy sales and markets with new products and services for customers and increasing shareholder value. The Company has realigned all areas of the business to support energy services and marketing functions. A new marketing plan, an expanded line of energy products and services, additional staff and new technologies are part of the Company's strategy for providing responsive and superior customer service. To strengthen the Company's competitive position, new technologies were added that enable employees to better serve customers. The company is centralizing activities to improve efficiency and customer responsiveness, and business processes are being reengineered to apply best-practices methodologies. Long-term supply contracts have been renegotiated to lower customers' energy costs, and new alliances help reduce expenses and add innovative work approaches. As described in Note 1 to the consolidated financial statements, the Company complies with the provisions of Statement of Financial Accounting Standards No. 71 (SFAS 71), "Accounting for the Effects of Certain Types of Regulation". SFAS 71 provides for the financial reporting requirements of the Company's regulated electric and natural gas operations which requires specific accounting treatment of certain costs and expenses that are related to the Company's regulated operations. Criteria that could give rise to the discontinuance of SFAS 71 include (1) increasing competition that restricts the Company's ability to establish prices to recover specific costs and (2) a significant change in the manner in which rates are set by regulators from cost-based regulation to another form of regulation. The Company periodically reviews these criteria to ensure the continuing application of SFAS 71 is appropriate. Based on a current evaluation of the various factors and conditions that are expected to impact future cost recovery, the Company believes that its regulatory assets, including those related to generation, are probable of future recovery. Weather conditions have a significant impact on the demand for propane for both heating and agricultural purposes. Many customers of Cornerstone rely heavily on propane as a heating fuel. Actual weather conditions can vary substantially from year to year, significantly affecting Cornerstone's financial performance. Furthermore, variations in weather in one or more regions in which Cornerstone operates can significantly affect the total volumes sold by Cornerstone and the margins realized on such sales and, consequently Cornerstone's results of operations. The retail propane business is a margin-based business in which gross profits depend on the excess of sales prices over propane supply costs. Consequently, Cornerstone's profitability will be sensitive to changes in wholesale propane prices. Propane is a commodity, the market price of which can be subject to volatile changes in response to changes in supply or other market conditions. As it may not be possible immediately to pass on to customers rapid increases in the wholesale cost of propane, such increases could reduce Cornerstone's gross profits. Cornerstone's profitability is affected by the competition for customers among all participants in the retail propane business. Some of Cornerstone's competitors are larger or have greater financial resources than Cornerstone. Should a competitor attempt to increase market share by reducing prices, Cornerstone's financial condition and results of operations could be materially adversely affected. In addition, propane competes with other sources of energy, some of which are less costly for equivalent energy value. Energy distribution growth will be increasingly important to the Company in the future. In addition to maintaining a strong competitive position in electric, natural gas and propane distribution businesses, the Company intends to seek new investments and acquisitions that have long-term growth potential. While such investments and acquisitions can involve increased risk in comparison to the Company's energy distribution businesses, they offer the potential for enhanced investment returns.

Nature of Operations: - --------------------- Northwestern Public Service Company is an investor-owned diversified energy distribution company with core operations engaged in the propane, electric and natural gas industries. The Company is engaged in the regulated utility business of production, purchase, transmission, distribution and sale of electricity and the delivery of natural gas. The Company serves 55,600 electric customers in eastern South Dakota and 77,478 natural gas customers in eastern South Dakota and central Nebraska. To provide baseload electric power, the Company jointly owns three coal-fired generating plants with other utilities. Through the acquisitions of Synergy Group Incorporated (Synergy) and Myers Propane Gas Company (Myers) in 1995 and Empire Energy Corporation (Energy) in 1996, the Company engaged in retail propane distribution business located throughout the United States. On December 17, 1996, a wholly owned subsidiary acquired CGI Holdings, Inc., (Coast) and combined the propane distribution businesses of Coast, Energy, Myers and Synergy (the Partnership Formation) into Cornerstone Propane, L.P., (the Operating Partnership), a Delaware limited partnership and a subsidiary of Cornerstone Propane Partners, L.P. (Cornerstone), a Delaware limited partnership, formed to acquire and operate these propane businesses and assets. Cornerstone and the Operating Partnership are collectively referred to herein as the Partnership. On December 17, 1996, as part of an initial public offering (IPO), Cornerstone sold a total of 9,821,000 common units (Common Units) representing limited partner interests. The Company through its majority owned subsidiaries retained an effective 2% general partner interest and a 39% limited partnership interest in the Partnership. A wholly owned subsidiary of the Company serves as the general partner (General Partner) of the Partnership and manages and operates the Partnership's business. (For a detailed description of the Partnership Formation and related transactions, see Note 2). The Company's manufacturing operations are comprised of Lucht Inc., a wholly owned subsidiary that develops, manufactures and markets multi-image photographic printers and other related equipment. Basis of Consolidation: - ----------------------- The accompanying consolidated financial statements include the accounts of Northwestern Public Service Company and all wholly and majority owned subsidiaries, including the Partnership. All significant intercompany balances and transactions have been eliminated from the consolidated financial statements. The Company's regulated businesses are subject to various state and federal agency regulation. The public unitholders' interest in Cornerstone's net assets subsequent to the Partnership Formation is reflected as a minority interest in the consolidated balance sheets. For purposes of determining the minority interest in Cornerstone, all 9,821,000 Common Units held by the public are considered to be outstanding as of December 31, 1996. Use of Estimates: - ----------------- The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Revenue Recognition and Gas Costs: - ---------------------------------- Electric and natural gas revenues are based on billings rendered to customers rather than on meters read or energy delivered. Customers are billed monthly on a cycle basis. Revenues from propane sales are recognized principally when fuel products are shipped or delivered to customers. Manufacturing revenue is recognized as equipment is shipped or delivered to customers. The commodity cost portion of natural gas purchased from wholesale suppliers but not yet billed to customers is charged to deferred gas costs. This account is subsequently credited in future periods as customers are billed for natural gas used in prior periods. This method has the approximate effect of matching costs with revenues in any financial reporting period. The demand cost portion of natural gas costs, which is comprised of numerous components, is expensed as incurred. The Company and its subsidiaries have propane and natural gas supply agreements with various suppliers for the purchase of these products in the normal course of their operations Allowance for Funds Used During Construction: - --------------------------------------------- The allowance for funds used during construction includes the costs of equity and borrowed funds used to finance construction which are capitalized in accordance with rules prescribed by the Federal Energy Regulatory Commission (FERC). In 1996, 1995 and 1994, allowance for equity funds was $95,000, $134,000 and $17,000. Allowance for borrowed funds for 1996, 1995 and 1994 was $83,000, $362,000 and $39,000. Cash Equivalents: - ----------------- The Company generally considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. Depreciation and Maintenance: - ----------------------------- Depreciation is computed using the straight-line method based on the estimated useful lives of the various classes of property. Depreciation provisions, as a percentage of the average balance of depreciable property, were 4.20% in 1996, 3.61% in 1995 and 3.39% in 1994. The percentages for 1996 and 1995 include propane related depreciation provision and depreciable property whose estimated useful lives principally range from 5 to 40 years. Depreciation rates include a provision for the Company's share of the estimated costs to decommission three coal-fired generating plants at the end of the useful life of each plant. The annual provision for such costs is included in depreciation expense, while the accumulated provisions are included in other deferred credits. The costs of maintenance, repairs and replacements of minor property items are charged to maintenance expense accounts. Costs of renewals and betterments of electric and natural gas property units are charged to property accounts. The costs of units of electric and natural gas property removed from service, net of removal costs and salvage, are charged to accumulated depreciation. No profit or loss is recognized in connection with ordinary retirements of depreciable electric and natural gas property. Goodwill and Other Intangibles: - ------------------------------- The excess of the cost of businesses acquired over the fair market value of all tangible and intangible assets acquired, net of liabilities assumed, has been recorded as goodwill which is being amortized on a straight-line basis over 40 years. Other intangibles, consisting principally of costs of covenants not to compete, are being amortized over the estimated periods benefited which do not exceed 10 years. Goodwill and other intangibles are reflected net of accumulated amortization at December 31, 1996 and 1995, of $1,199,000 and $1,188,000. It is the Company's policy to review property, goodwill, and other intangible assets for possible impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. If such review indicates that the carrying amount is not recoverable, it is the Company's policy to reduce the carrying amount of these assets to fair value. Investments and Fair Value of Financial Instruments: - ---------------------------------------------------- The Company's investments consist primarily of short maturity fixed income securities and corporate preferred and common stocks. In addition, the Company has investments in privately held entities and ventures, safe harbor leases and various money market and tax exempt investment programs. These investments are accounted for in accordance with Statement of Financial Accounting Standards No. 115 (SFAS 115), "Accounting for Certain Investments in Debt and Equity Securities". SFAS 115 requires that certain investments in debt and equity securities be reported at fair value. The Company's securities are classified under the provisions of SFAS 115. As of December 31, 1996, the fair value, cost and the gross unrealized gain of the Company's available for sale investments were $31,742,000, $31,740,000 and $2,000 for preferred stock investments and $16,264,000, $1,118,000 and $15,146,000 for marketable securities. As of December 31, 1995, the fair value, cost and the gross unrealized gain of the Company's available for sale investments were $37,746,000, $37,592,000 and $154,000 for preferred stock investments and $9,892,000, $1,271,000 and $8,621,000 for marketable equity securities. The unrealized gain, net of tax, at December 31, 1996 and 1995, was $9,846,000 and $5,704,000, respectively. Held to maturity securities are reported at cost, which approximated fair value and at December 31, 1996 and 1995 was $111,327,000 and $4,269,000. The Company uses the specific identification method for determining the cost basis of its investments in available for sale securities. Gross proceeds and realized gains and losses on sales of its available for sale securities were not material in 1996 and 1995. Based on current market rates for debt of similar credit quality and remaining maturities or quoted market prices for certain issues, the face value of the Company's long-term debt approximates its market value. Income Taxes: - ------------- Deferred income taxes relate primarily to the difference between book and tax methods of depreciating property, taxable income derived from safe harbor leases, the difference in the recognition of revenues for book and tax purposes, and natural gas costs which are deferred for book purposes but expensed currently for tax purposes. For book purposes, investment tax credits were deferred and are being amortized as a reduction of income tax expense over the useful lives of the property which generated the credits. Regulatory Assets and Liabilities - --------------------------------- The Company is subject to the provisions of Statement of Financial Accounting Standards No. 71 (SFAS 71), "Accounting for the Effects of Certain Types of Regulations". Regulatory assets represent probable future revenue to the Company associated with certain costs which will be recovered from customers through the ratemaking process. Regulatory liabilities represent probable future reductions in revenues associated with amounts that are to be credited to customers through the ratemaking process. If all or a separable portion of the Company's operations becomes no longer subject to the provisions of SFAS 71, an evaluation of future recovery from related regulatory assets and liabilities would be necessary. In addition, the Company would determine any impairment to the carrying costs of deregulated plant and inventory assets. Reclassifications: - ------------------ Certain 1995 and 1994 amounts have been reclassified to conform to the 1996 presentation. Such reclassifications had no impact on net income or common stock equity as previously reported. (2) Master Limited Partnership Offering and Business Acquisitions - Master Limited Partnership Offering: - ------------------------------------ On December 17, 1996, a wholly owned subsidiary of Northwestern Growth Corporation acquired Coast. Immediately after the acquisition the Company combined the propane distribution businesses of Coast, Energy, Myers and Synergy into Cornerstone. As part of an IPO on the same date, Cornerstone sold a total of 9,821,000 Common Units at a price to the public of $21 a unit. Cornerstone's capital consists of 9,821,000 Common Units, 6,597,619 subordinated units (Subordinated Units) representing limited partner interests and a 1% general partner interest. The Company's majority owned subsidiaries own all 6,597,619 Subordinated Units and an aggregate 2% general partner interest in the Partnership, or a combined 41.4% effective interest in the Partnership. The net proceeds of $191.8 million from the sale of 9,821,000 Common Units of Cornerstone and the net proceeds from the issuance of $220 million face value of Cornerstone Senior Notes were used to repay term and revolving debt of Coast, Energy and Synergy, including accrued interest and any prepayment premiums which were assumed by the Partnership. In addition, the preferred stock of Synergy was redeemed at a premium. As a result of these repayments, the Company recorded a one-time after tax gain of $.19 per share from the prepayment of the term debt and redemption of preferred stock investment in Synergy. The Partnership makes distributions to its partners with respect to each fiscal quarter of the Partnership in an aggregate amount equal to its Available Cash for such quarter. Available Cash generally means, with respect to any fiscal quarter of the Partnership, all cash on hand at the end of such quarter plus all additional cash on hand as of the date of determination resulting from borrowings subsequent to the end of such quarter, less the amount of cash reserves established by the General Partner in its reasonable discretion for future cash requirements. These reserves are retained for the proper conduct of the Partnership's business, for the payment of debt principal and interest and for distributions during the next four quarters. Distributions by the Partnership, in an amount equal to 100% of its Available Cash, will generally be made 98% to the Common and Subordinated unitholders and 2% to the General Partners. Distributions are subject to the payment of incentive distributions in the event Available Cash exceeds the Quarterly Distribution of $.594 on all units. To the extent there is sufficient Available Cash, the holders of Common Units have the right to receive the Minimum Quarterly Distribution, plus any arrearages, prior to the distribution of Available Cash to holders of Subordinated Units. Common Units will not accrue arrearages for any quarter after the Subordination Period (as defined below), and Subordinated Units will not accrue any arrearages with respect to distributions for any quarter. The Subordination Period will generally extend until the first day of any quarter beginning on or after December 31, 2001, in respect of which (a) distributions of Available Cash from operating surplus equal or exceed the Minimum Quarterly Distribution on each of the outstanding Common and Subordinated units for each of the three consecutive four-quarter periods immediately preceding such date, (b) the adjusted operating surplus generated during each of the three consecutive four-quarter periods immediately preceding such date equals or exceeds the Minimum Quarterly Distribution on each of the Common and Subordinated units and the related distribution on the general partner interests in the Partnership during such periods and (c) there are no outstanding Common Unit arrearages. In addition, 1,649,405 Subordinated Units will convert into Common Units for any quarter ending on or after December 31, 1999, and an additional 1,649,405 Subordinated Units will convert into Common Units for any quarter ending on or after December 31, 2000, if (a) distributions of Available Cash from operating surplus on each of the outstanding Common and Subordinated units equal or exceed the Minimum Quarterly Distribution for each of the three consecutive four-quarter periods immediately preceding such date, (b) the adjusted operating surplus generated during the immediately preceding two consecutive four-quarter periods equals or exceeds the Minimum Quarterly Distribution on all of the Common and Subordinated units outstanding during that period and (c) there are no arrearages on the Common Units. The Partnership will make distributions of its Available Cash approximately 45 days after the end of each quarter ending March, June, September and December to holders of record on the applicable record dates. Business Acquisitions: - ---------------------- On August 15, 1995, the Company completed the acquisition of Synergy, a retail distributor of propane. Synergy maintained 152 retail branches serving approximately 200,000 customers in 23 states, primarily in suburban and rural areas of the eastern and south-central regions of the United States. In conjunction with the acquisition, the Company sold certain retail property outlets to Energy, which was later acquired in October 1996. The Synergy transaction represented an initial cash investment by the Company of approximately $137.5 million, but after the sale of certain retail property outlets, the total net cash acquisition investment by the Company was $105.6 million. The Company made debt and preferred stock investments in SYN Inc., the entity created to acquire Synergy. Northwestern Growth Corporation, one of the Company's wholly owned subsidiaries, owned control of SYN Inc. common stock. The acquisition was accounted for under the purchase method of accounting. The total net purchase price was comprised of consideration paid of $105.6 million cash, issuance of $1.25 million in long-term debt and the assumption of certain liabilities and other long-term debt. The cost in excess of the fair value of the net tangible and intangible assets acquired and the costs related to arranging the debt financing for the acquisition of $31.7 million have been recorded as intangible assets and are being amortized on a straight-line method over 40 years. The allocation of the purchase price to the acquired assets and liabilities of Synergy was based on fair value of the related assets and liabilities. The Company has asserted claims under the acquisition agreement for post-closing adjustments related to the acquisition of Synergy. If these claims are successful, an adjustment in the consideration paid for the acquisition could result. The Company's investments in SYN Inc. were funded primarily by financings undertaken in 1995. During the third quarter of 1995, the Company issued $60 million of 7.10% general mortgage bonds due August 1, 2005, 1.3 million shares of 8 1/8% preferred securities of subsidiary trust and 1.2 million shares of common stock. On December 7, 1995, the Company acquired majority control of Myers through the issuance of 42,890 shares of common stock and 11,500 shares of 6 1/2% redeemable cumulative preferred stock. Myers is a retail distributor of propane serving approximately 4,500 customers in and around Sandusky, Ohio. The total purchase price of $4.8 million was comprised of the securities issued by the Company seller financing. The acquisition was accounted for under the purchase method of accounting. The cost in excess of fair value of the net assets acquired of $1.9 million has been classified as goodwill and is being amortized on a straight-line method over 40 years. On October 7, 1996, the Company completed the acquisition of Energy, a retail distributor of propane. Energy maintained 168 retail branches serving approximately 130,000 customers in 10 states, primarily in southeast and midwest regions of the United States. The total purchase price of $120 million was comprised of cash, assumption of certain liabilities including long-term debt of $94 million, and transaction related costs. The cost in excess of the fair value of the net tangible assets acquired has been classified as goodwill and is being amortized on a straight-line method over 40 years. The allocation of the purchase price to the acquired assets and liabilities of Energy was based on fair value of the related assets and liabilities. Had the acquisitions of Coast, Energy, Myers, and Synergy and the Partnership Formation occurred on January 1, 1995, combined unaudited pro forma results for the years ended December 31, 1996 and 1995, as prescribed under Accounting Principles Board Opinion No. 16 (APB 16), "Business Combinations", would have been: Revenues $770,031,000 and $620,887,000, net income $18,771,000 and $16,437,000 and earnings per share $2.10 and $1.84. The pro forma disclosures required under APB 16 are not indicative of past or future operating results. Since the acquisitions and Partnership Formation, the Company has implemented significant cost reduction measures principally related to elimination of certain employee positions, corporate administrative expenses and other specifically identified operating expenses that have not been reflected in the pro forma information under the provisions of APB 16. (3) Short-Term Borrowings - The Company may issue short-term debt in the form of bank loans and commercial paper as interim financing for general corporate purposes. The bank loans may be obtained under short-term lines of credit. The Company's aggregate lines of credit available are $24 million at December 31, 1996. The Company pays an annual fee equivalent to 1/4% of the unused lines. There were no line of credit borrowings outstanding at December 31, 1996 and 1995. At December 31, 1996, the Company had no outstanding commercial paper borrowings. At December 31, 1995, the Company had outstanding $3.5 million of commercial paper. (4) Long-Term Debt - Substantially all of the Company's electric and gas utility plant is subject to the lien of the indentures securing its general mortgage bonds and pollution control obligations. General mortgage bonds of the Company may be issued in amounts limited by property, earnings and other provisions of the mortgage indenture. The following table summarizes the Company's general mortgage bonds and pollution control obligations at December 31 (in thousands): Series Due 1996 1995 ----------------------- -------- -------- -------- General mortgage bonds - 8.824% 1998 $ 15,000 $ 15,000 8.9% 1999 7,500 7,500 6.99% 2002 25,000 25,000 7.10% 2005 60,000 60,000 7% 2023 55,000 55,000 Pollution control obligations - 5.85%, Mercer Co., ND 2023 7,550 7,550 5.90%, Salix, IA 2023 4,000 4,000 5.90%, Grant Co., SD 2023 9,800 9,800 -------- -------- $183,850 $183,850 ======== ======== In conjunction with the Partnership Formation in December 1996, the Partnership issued $220 million in First Mortgage Notes (Notes). These Notes are collateralized by substantially all of the assets of the Partnership and ranks pari passu with the Bank Credit Facility. The Notes bear interest at a fixed rate of 7.53% payable semi-annually and mature in the year 2010 with eight equal annual installments beginning in the year 2003. The Partnership may, at its options and under certain circumstances following the disposition of assets be required to offer to prepay the Notes, in whole or in part. The Note agreement contains restrictive covenants applicable to the Partnership, including (a) restrictions on the incurrence of additional indebtedness, (b) restrictions on the ratio of consolidated cash flow to consolidated interest expense of the Partnership, as defined, and (c) restrictions on certain liens, loans and investments, payments, mergers, consolidations, sales of assets and other transactions. Generally, as long as no default exists or would result, the Partnership is permitted to make cash distributions not more frequently than quarterly in an amount not to exceed available cash, as defined, for the immediately preceding calendar quarter. The Partnership also entered into a Bank Credit Facility in December 1996 with a group of commercial banks. The Bank Credit Facility consists of a $50 million Working Capital Credit Facility and a $75 million Acquisition Facility to finance propane business acquisitions. There were $10,445,000 of borrowings outstanding under Working Capital Facility at December 31, 1996. There were no outstanding borrowings on the Acquisition Facility at December 31, 1996. The Bank Credit Facility bears interest at a variable rate tied to a certain Eurodollar index or prime rate, plus a variable margin for either rate which depends upon the Partnership's ratio of consolidated debt to consolidated cash flow. The Bank Credit Facility matures in December 1999. The Bank Credit Facility is collateralized by substantially all the assets of the Partnership and ranks pari passu with the First Mortgage Notes. The Bank Credit Facility contains restrictive covenants applicable to the Partnership, including (a) restrictions on the incurrence of additional indebtedness, (b) restrictions on the ratio of consolidated cash flow to consolidated interest expense of the Partnership, as defined, and (c) restrictions on certain liens, loans and investments, payments, mergers, consolidations, sales of assets and other transactions. They also require that the Partnership maintain a ratio of total funded indebtedness to consolidated cash flow, as defined. Generally, as long as no default exists or would result, the Partnership is permitted to make cash quarterly distributions in an amount not to exceed Available Cash, as defined. Lucht Inc. has a credit agreement with a bank whereby it may borrow up to $8 million in revolving and term loans. Balances of $3,290,000 and $4,802,500 were outstanding under the revolving and term loan as of December 31, 1996 and 1995, at a weighted average interest rate of 8%. Borrowings under the agreement are collateralized by all receivables, inventories, property and other assets of Lucht, and are nonrecourse to the Company. SYN Inc. had a credit agreement with a bank whereby it could borrow up to $30 million in revolving loans. The facility was repaid in conjunction with the Partnership Formation. A balance of $21,342,320 was outstanding under the facility as of December 31, 1995.
