ITEM 1. BUSINESS As used herein, the terms (Wainoco) and (Company) refer to Wainoco Oil Corporation and its subsidiaries. Wainoco was originally incorporated in Canada in 1949 and changed its jurisdiction of incorporation to Wyoming in 1976. The Company's Canadian assets are held by Wainoco Oil Corporation, a Wyoming corporation, its United States oil and gas operations assets are held through its subsidiary, Wainoco Oil & Gas Company, a Delaware corporation, and its refining operations assets are held through its subsidiary, Frontier Holdings Inc. (Frontier), a Delaware corporation. Wainoco explores for and produces oil and gas in North America, principally in western Canada, selected areas of the midcontinent, the Los Angeles Basin and the Gulf Coast (onshore and offshore). The oil and gas activities of the Company consist of geological and geophysical evaluation of prospective oil and gas properties, the acquisition of oil and gas leases or other interests in exploratory prospects, the drilling of test wells, the acquisition of interests in developed or partially developed properties and the development and operation of properties for the production of oil and gas. At December 31, 1993, approximately 85% of the Company's proved reserves, on a British Thermal Unit (BTU) equivalent basis, was natural gas. During 1993, oil represented 40% and gas represented 60% of oil and gas revenues. The Company's oil and gas exploration and production activities are conducted directly by the Company or through joint drilling and operating arrangements. Wainoco acts as the operator of the majority of its production and prospects. Wainoco is also engaged in the business of crude oil refining and wholesale marketing of refined petroleum products, including various grades of gasoline, diesel fuel, asphalt, natural gas liquids and petroleum coke. Wainoco owns and operates an approximately 38,000 barrel per day (BPD) crude oil refinery (the Refinery), located in Cheyenne, Wyoming. In addition, the Company purchases the crude oil to be refined and markets the refined petroleum products produced by the Refinery. The Company's products which accounted for more than 10% of consolidated revenues were as follows: gasoline at 34%, distillates at 21%, natural gas at 18% and oil at 16% in 1991, and gasoline at 53% and distillates at 28% in 1992, gasoline at 50% and distillates at 29% in 1993. The Company also owns a 25,000 BPD undivided interest in a crude oil pipeline (Pipeline) running from Guernsey Station, Wyoming to Cheyenne, Wyoming. The Company directs its activities from its corporate office in Houston, Texas and its division offices in Calgary, Alberta, Canada and Denver, Colorado. Oil and Gas Exploration and Production Operations Canada - Activities in Canada are conducted through Wainoco Oil Corporation with emphasis on exploration, development and production in the western Canadian provinces of British Columbia and Alberta. At December 31, 1993, approximately 72% of estimated proved gas reserves, approximately 33% of estimated proved oil reserves and approximately 26% of identifiable assets of the Company were located in western Canada. For the year ended December 31, 1993, Canadian operations contributed approximately 55% of the Company's oil and gas revenue. During 1993, the exchange rate of the Canadian dollar averaged approximately U.S. $.7750. The accounts of the Canadian division have been translated in accordance with generally accepted accounting principles as described in Note 1 of the Financial Statements in the 1993 Annual Report to Shareholders which is incorporated herein by reference. United States - Activities in the United States are conducted through Wainoco Oil & Gas Company with the major emphasis of exploration, development and production of properties in selected areas of the midcontinent, the Los Angeles Basin and the Gulf Coast (onshore and shallow offshore regions).
Refining Operations Wainoco's refining activities are conducted through Frontier, which was acquired in October 1991. The Refinery is located on approximately 120 acres in Cheyenne, Wyoming, all of which are owned by the Company. The Refinery has a permitted crude capacity of 41,000 BPD with an effective operating capacity of 38,000 BPD, which represents approximately 7% of the rated crude distillation capacity in the Rocky Mountain region. The Refinery can also process in excess of 4,000 BPD of purchased natural gasoline, butanes and other petroleum liquids. One of Frontier's competitive advantages relative to most other Rocky Mountain refineries is that it includes substantially all of the major refinery units that comprise a complex refinery, including a coker. Therefore, the Refinery has the capability of producing a higher yield of lighter, more valuable petroleum products such as gasoline and diesel fuel from heavier, less costly feedstocks such as heavy sour crude oil. The Refinery's units have the capacity to process a high percentage (up to 90%) of lower cost, more abundant sour crude oil. The plant's downstream unit configuration affords the Refinery gasoline octane capability equal to or higher than that of most of its competitors. Frontier owns a 25,000 BPD undivided interest in a crude oil pipeline from Guernsey, Wyoming to Cheyenne. This pipeline was constructed to help serve the Refinery's long-term strategic crude oil needs.
Industry Segments The Company's industry segment information for the three years ended December 31, 1993, is set forth in Note 7 of the Financial Statements in the 1993 Annual Report to Shareholders which is incorporated herein by reference.
Operating Hazards and Risks The Company's oil and gas exploration and production operations are subject to all of the risks normally incident to the exploration for and production of oil and gas including blow-outs, cratering, pollution and fires, each of which could result in damage to or destruction of oil and gas wells or production facilities or damage to persons and property. As is common in the oil and gas industry, the Company is not fully insured against all of these risks, either because insurance is not available or because the Company has elected not to insure due to high premium costs. The occurrence of a significant event which was not fully insured could have a material adverse effect on the Company's financial position. The Company's refinery operations are subject to significant interruption if the refinery were to experience a major accident or fire or if it were damaged by severe weather or other natural disaster. Should the crude oil pipeline become inoperative, crude oil would be supplied to the Refinery by an alternative pipeline and from additional tank trucks. A substantial portion, but not all, of such loss would be covered by business interruption, property or other insurance carried by Frontier. Frontier's safety measures substantially mitigate but do not eliminate the risk of damage to the Refinery or the environment and personal injury should a major adverse event occur. The occurrence of a significant event which was not fully insured could have a material adverse effect on the Company's financial position.
Competition Oil and gas operations - The Company encounters strong competition from other independent operators and from major oil companies in acquiring properties suitable for exploration, in contracting for drilling equipment, in securing trained personnel and in marketing oil and gas production. Many of these competitors have financial resources and staffs substantially larger than those available to the Company. The availability of a ready market for oil and gas discovered by the Company depends on numerous factors beyond its control including the extent of production and imports of oil and gas, the demand for its products, the proximity and capacity of natural gas pipelines and the effect of state, provincial or federal regulations. Competition in the acquisition of oil and gas prospects and properties has been intense and remains so for prime prospects. The Company's ability to discover reserves depends on its ability to select and acquire suitable prospects for future exploration. Although the Company generates the major portion of its oil and gas prospects internally, it depends to some extent upon prospects offered to it by independent consultants and other persons or entities in the petroleum industry.
Refining operations - Frontier's business is highly competitive and price is the principal basis of competition. The most important competitive product marketing area in the Rocky Mountain region is the Denver market, principally because it is the major population center in the Rockies. There are at least 17 refineries in the Rocky Mountain region (including those owned by several major integrated oil companies). In addition, two refineries are located in Denver and two product pipelines from outside the Rockies terminate in the area with an additional product pipeline to be completed in 1994. Frontier also serves western Nebraska and eastern Wyoming. Many of the refineries in the Rocky Mountain region are owned by companies that have significantly greater financial resources and/or refining capacity than Frontier. Certain of these competitors, as integrated oil companies, also have the advantage of owning or controlling crude oil reserves or other sources of crude oil supply, crude oil and product pipelines and service stations and other product marketing outlets. Principal Competitors. Based on proximity to the Denver and Cheyenne areas, Frontier's principal competitors in the wholesale segment are Sinclair Oil Company (Sinclair) with a 54,000 BPD refinery near Rawlins, Wyoming and a 22,000 BPD refinery in Casper, Wyoming, Total Petroleum (North America) Ltd. (Total) with a 32,000 BPD refinery in Denver, Colorado and Conoco, Inc. (Conoco) with a 50,000 BPD refinery in Denver, Colorado. Frontier sells its products exclusively at wholesale, principally to independent retailers, jobbers and major oil companies, while Sinclair, Total and Conoco service both the retail and wholesale markets. Frontier is favorably positioned to purchase its crude oil and feedstock requirements. Because many other refiners in the Rocky Mountain region have significantly lower sour crude capacity, Frontier faces less competition for regionally produced crude oil, which is predominantly sour. Regional production of crude oil still exceeds regional refining capacity. Frontier on occasion also purchases Canadian sour crude oil, which is available via pipeline into Guernsey, Wyoming. Frontier and its principal competitors all service the Denver market. Because their refineries are located in Denver, Total's and Conoco's product transportation costs in servicing that area are lower than those of Frontier. Conversely, Frontier has lower crude transportation costs due to its proximity to Guernsey, Wyoming, the major crude oil pipeline hub in the Rocky Mountain region, and further due to its ownership interest in the crude oil pipeline. Capital Improvement Program. During 1993, Frontier completed a significant capital improvement program for the refinery. The most significant projects included: (i) the construction of new sulfur recovery and amine treating units which increased sour crude processing capacity, (ii) the expansion of the capacity of the delayed coker unit from 8,200 bpd to 10,000 bpd, (iii) the upgrading and expansion of the distillate hydrotreater and construction of a hydrogen plant for adequate hydrogen supply and (iv) several projects which improve the reliability and safety of various refinery units. The capital improvement program enables the refinery to produce low sulfur diesel as required by the Clean Air Act Amendments of 1990, increases the amount of sour crude processed and improves the operating reliability of the refinery. The improvements also increased the refinery's diesel capacity. In addition, Frontier has incurred capital expenditures as a result of Occupational Safety and Health Act (OSHA) required studies and the replacement of equipment damaged in a June 1992 fire. Strategic Position. Wainoco believes that, because the Refinery includes substantially all of the major refinery units that comprise a complex refinery, it potentially has three significant advantages over its principal competitors and most other refineries in the region. First, the Refinery has the capacity to process a high percentage (up to 90%) of sour crude oil, while most refineries in the Rocky Mountain region can process only sweet crude or smaller percentages of sour crude. Refineries that have the ability to process sour crude can benefit from the significantly lower cost of sour relative to sweet crude oil, which is often referred to as the "sweet/sour spread." During 1993, Frontier's cost for sour crude oil has ranged from approximately $3.78 to $4.89 per barrel lower than its cost for sweet crude. Second, Frontier owns a 10,000 BPD coker, which, among other things, enables the Refinery to upgrade resid and other heavy feedstocks into lighter, more valuable petroleum products. Coker capacity was expanded to 10,000 BPD at the end of 1992 to accommodate a 10-year agreement to process heavy feedstocks for Conoco. There are presently only four other cokers in the region. Third, because of Frontier's combination of downstream process units, the Company believes that the Refinery has octane capability equal to or greater than most of its competitors. This capability enabled Frontier to be the first to introduce 91 octane premium unleaded gasoline to the Rocky Mountain region. (Due to different altitudes, gasoline used in the Rocky Mountain region generally has an octane rating two points lower than corresponding grades of gasoline elsewhere in the United States.) In addition, as a result of stringent environmental protection laws and the high cost of the requisite plant modifications, Wainoco believes that, in general, refiners in the Rocky Mountain region will face barriers to substantially expanding refinery capacities or sour crude processing capability. Based in part on the foregoing factors, the Company believes that, assuming Frontier continues to reduce unplanned refinery unit shutdowns and other equipment problems, Frontier is capable of competing effectively in its market. In particular, Frontier has sold and expects to continue to sell refined products at competitive prices. Markets. Frontier sells to a broad base of independent retailers, jobbers and major oil companies in the region. Its largest customer, CITGO Petroleum Products, comprises approximately 15% of Frontier's 1993 sales. Customer relations are excellent. Prices are determined by local marketing conditions and at the "terminal rack" such that the customer typically supplies his own truck transportation. Effect of Crude Oil and Refined Product Prices. Frontier's income and cash flow are derived from the margin between its costs to obtain and refine crude oil and the price for which it can sell products produced in its refining process. The price at which Frontier can sell gasoline and its other refined products will be strongly influenced by the price of crude oil. Although an increase or decrease in the price of crude oil generally results in a corresponding increase or decrease in the price of gasoline and refined products, changes in the prices of refined products generally lag behind changes in the price for crude oil, both upward and downward. Frontier maintains inventories of crude oil, intermediate products and refined products, the value of each of which is subject to rapid fluctuations in market prices. Inventories are recorded at the lower of cost on a first in, first out (FIFO) basis or market. A rapid and significant movement in the market prices for crude oil or refined products could have an adverse short-term impact on earnings and cash flow. Crude oil prices, in general, are affected by a number of factors, including domestic and international demand, domestic and foreign energy legislation, production guidelines established by the Organization of Petroleum Exporting Countries (OPEC), relative supplies of other fuels, such as natural gas, and changing international economic and political conditions. Frontier can process a high percentage of sour crude oil, enabling it to benefit from the lower cost of sour crude relative to sweet crude. Because income and cash flow from refining operations are dependent in part on this cost differential, any narrowing of the sweet/sour crude spread would likely cause a reduction in operating margin and a decrease in earnings and cash flow of the refinery. A narrowing of the sweet/sour crude spread could result from, among other things, a decrease in the supply of sour crude or an increase in sour crude refining capacity of the refinery's competitors. General - Wainoco competes with other oil and gas concerns and other investment opportunities, whether or not related to the petroleum industry, in raising capital. The Company's ability to compete successfully in the capital markets is largely dependent on the success of its oil and gas exploration activities, refining activities and the economic environment in which it operates.
Current Gas Markets The Company continues to sell the majority of its natural gas production to long-term gas contracts managed by companies (aggregators) who purchase large volumes of natural gas from many producers and resell this gas throughout North America. The price paid for this gas is a "net-back" price per unit of gas established by subtracting transportation, processing, storage and administrative costs from the total revenue generated from all the monthly sales of gas. During 1993, North America appears to have established a balance of demand and supply of natural gas. During earlier periods of lower load factors, the Company negotiated the right to market such excess volumes not taken by the primary purchaser, to other markets. Such excess volumes are sold in the spot market. Wainoco has utilized short term contracts to ensure a diversification of end-users, and optimize production. Generally, one year renewable contracts have been used for this purpose. Gas prices are normally negotiated annually as a fixed price per unit of sales or an indexed price compared to the NYMEX futures price. Firm transportation and gas processing capacity from major pipeline companies have been obtained in Canada to ensure continued ability to produce pursuant to these contracts. Prior to November 1, 1993, approximately 28% of the Canadian gas sold by the Company was supplied under contracts that provide for supplies of fixed volumes of gas. If the Company were not able to supply the gas required under these contracts (as a result of high demand, for example), it would have been required to fulfill its supply obligations by purchasing gas in the spot market, where prices may exceed the contract prices. Subsequent to November 1, 1993, the risk of such future losses was mitigated through contract expirations and other factors.
Government Regulations Oil & Gas Operations - Environmental Laws and Regulations. The Company's oil and gas exploration and production activities are subject to laws and regulations relating to environmental quality and pollution control. The Company believes that such legislation and regulations have had no material adverse effect on its present method of operation. In the future, changes in Canadian or United States federal, state, provincial and local government environmental controls could require the Company to make significant expenditures. The magnitude of such expenditures cannot be predicted. Environmental legislation in Alberta has undergone a major revision to update and consolidate the various acts now applicable to the industry into the Environmental Protection and Enhancement Act (EPEA) effective September 1, 1993. The EPEA brings a wider range of activities within the scope of environmental regulation. Environmental standards and penalties are generally stricter under the EPEA than under the environmental regulatory regime it replaces. Canadian Oil and Gas Operations. Wainoco's Canadian oil and gas production is subject to the payment to provincial governments, among others, of a specified percentage of production revenue as a royalty. Royalties paid to the province of Alberta are subject to a rebate called the Alberta Royalty Tax Credit (ARTC). The ARTC is based on a price-sensitive formula using the average West Texas Intermediate (WTI) quarterly oil price. The maximum annual ARTC limits in 1993, 1992 and 1991 were $1.4 million, $1.5 million and $1.3 million, respectively. The Company recognized ARTC's of $621,000, $590,000 and $558,000 in 1993, 1992 and 1991, respectively. The Alberta government has made changes and continues to consider further changes in its royalty structure (including royalty exemption periods) to provide incentives for exploring and developing oil and gas reserves. The government of Canada has relaxed export criteria to expand the export of natural gas and has a broad policy wherein exports to the United States will be sold at prices no lower than those prices in the adjoining Canadian market for comparable end-users. The Free Trade Agreement implemented in 1989 between Canada and the United States was intended to foster a more open North American marketplace with a minimum of direct government interference. Both countries are prohibited from imposing minimum export or import price requirements or maintaining any discriminatory export taxes, duties or charges. The agreement also provides for the elimination of the United States tariffs and the elimination of customs user fees which were previously imposed. The North American Free Trade Agreement (NAFTA) implemented in 1994 between the Governments of Canada, the United States and Mexico provides for the reduction of Mexican restrictive trade practices in the energy sector and prohibits discriminatory border restrictions and export taxes. NAFTA also provides for clearer disciplines on regulators to avoid discriminatory actions and to minimize disruption of contractual arrangements, which is important for Canadian natural gas exports. United States Oil and Gas Operations. The Company is subject to regulation with respect to various aspects of its natural gas operations under the Natural Gas Act and the Natural Gas Policy Act of 1978. Additionally, the Company is significantly affected by certain provisions of the federal income tax laws applicable to the petroleum industry.
Refinery Operations - The Company's refinery operations are subject to laws and regulations relating to environmental quality and pollution control. In 1992 and 1993, the Company incurred capital costs of approximately $34.9 million to upgrade refinery equipment for the manufacture of clean burning diesel fuel as mandated by the Clean Air Act Amendments of 1990 (the Act). Additional regulations now being developed under the Act will likely require certain additional, but lesser, expenditures in the coming years. Although these new requirements are not yet final, up to an estimated $1 million may be expended over the next two years to facilitate conventional gasoline formulation and approximately $4 million may be required over four years beginning in 1995 to improve refinery controls on emissions of certain petroleum materials designated as hazardous by the Act. Because other refineries will be required to make similar expenditures, the Company does not expect such expenditures to materially adversely impact its competitive position. Frontier is party to formal agreements with both state and federal agencies requiring the investigation and possible eventual remediation of certain areas of refinery property which may have been impacted by past operational activities. The Company has been addressing, over the past eight years, tasks required under a consent decree (Consent Decree) entered by the Wyoming State District Court on November 28, 1984 and involving the State of Wyoming, Department of Environmental Quality and the predecessor owners of the refinery. This action primarily addressed the threat of groundwater and surface water contamination at the refinery. As a result of these investigative efforts, substantial capital expenditures and remediation of conditions found to exist have already taken place or are in progress. The continuing requirement for groundwater remediation activities is the only significant task remaining in connection with the Consent Decree. Additionally, Frontier entered into a consent order with the federal Environmental Protection Agency on September 24, 1990 pursuant to the Resource Conservation and Recovery Act. The order requires the technical investigation of the refinery to determine if certain areas of the refinery have been adversely impacted by past operational activities. Based upon the results of the investigation, additional remedial action could be required. The Company has been and will be responsible for costs related to compliance with or remediations resulting from environmental regulations. There are currently no identified environmental remediation projects of which the costs can be reasonably estimated. However, the continuation of the present investigative process, other more extensive investigations over time or changes in regulatory requirements could result in future liabilities. See the Financial Review of the 1993 Annual Report to Shareholders which is incorporated herein by reference for discussion concerning the impact of compliance with environmental laws and regulations on the Company's capital expenditures and earnings.
Seasonality At the Refinery, due to seasonal increases in tourist related volume and road construction work, a higher demand exists in the Rocky Mountain region for gasoline and asphalt products during the summer months than during the winter months. Diesel demand is relatively constant throughout the year because two major east-west truck routes, and at least two railroads, extend into or through Frontier's principal marketing area. However, reduced road construction during the winter months does somewhat reduce demand for diesel. The Refinery normally schedules its maintenance turnaround work during the spring of each year. During the spring of 1994, the Refinery has scheduled turnaround work on two of its major operating units.
Employees At December 31, 1993, the Company had 417 full-time employees, down from 434 a year earlier. The Company's 97 full-time employees in oil and gas operations include 7 geologists, 3 geophysicists, 3 land men in exploration and development and 10 petroleum engineers in drilling and production. The Company employs 309 full-time people in the refining operations, 43 at the Denver office and 266 at the Refinery. The Refinery employees include 83 administrative and technical personnel and 183 union members. The union members are represented by seven bargaining units, the largest being the Oil, Chemical and Atomic Workers International Union. Six AFL-CIO affiliated unions represent the Refinery's craft workers. The Company considers relations with all of its employees to be good. The current three-year contracts expire in May 1996.
