We were not immune to commodity price volatility FINANCIAL RESULTS In 2014 we achieved: • Net Income attributable to HFC stockholders of $281 million, $525 million excluding the lower of cost or market “LOCM” adjustment • Gross refining margins of $13.98 per produced barrel • Operating cash flow of $758.6 million • $1 billion in cash and short-term investments as of December 31, 2014, compared to approximately $187 million in long-term debt (exclusive of HEP debt) • Over $780 million of capital returned to shareholders in 2014, during which domestic crude prices plummeted 46% and the WTI/Brent crude differential compressed 40%. Our reported gross margin per barrel declined only 13% to $13.98 per barrel reflecting our advantaged geographic location close to inland crude production and niche product markets. 2 HollyFrontier Corporation 2014 Annual Report In 2014, HollyFrontier delivered improved operational perfor- mance across our refineries. We are seeing the benefit of past and ongoing investments being made across our refining system. Our consolidated refinery utilization rate in 2014 was 91.7%, above our five-year average utilization rate and nearly a 5% improvement relative to 2013 levels due to a combination of less planned maintenance activity and lower unplanned downtime. In 2015 and beyond, we will continue to focus on improving our operational efficiency, reliability, advantaged crude access and refinery yield improvement. STRONG TRACK RECORD OF RETURNING CAPITAL TO STOCKHOLDERS HollyFrontier remains committed to generating shareholder value by returning cash to shareholders. In 2014, HollyFrontier returned over $780 million to stockholders through regular quarterly dividends, special dividends and share repurchases. On an annualized basis, the Company’s cash dividend yield was 8.7% as of year-end 2014. In February 2015, the Board of Direc- tors authorized a new $500 million share repurchase program reflecting our renewed focus on share repurchases to augment our dividend program. Since completing the HollyFrontier merger in July 2011, the Company has returned approximately $2.8 billion in capital to stockholders. INVESTING IN OUR OPERATIONS In 2014, we invested $485 million in our facilities improving our refining capabilities, safety and refinery reliability and minimizing our environmental impact. Several of our investments are scheduled to complete in 2015 and once operational will augment HollyFrontier’s margins and drive sustainable long-term value. Our 2014 capital investment projects included: “ In 2014, HollyFrontier delivered improved operational performance across our refineries. We are seeing the benefit of past and ongoing investments being made across our refining system.” MICHAEL C. JENNINGS • Woods Cross Refinery Expansion: Our Woods Cross expansion will increase capacity at our Woods Cross facility located near Salt Lake City, Utah from 31,000 to 45,000 barrels per day while at the same time reducing emissions. As part of the expansion, we are increasing our capacity to process locally sourced black wax crude from 10,000 barrels to 24,000 barrels a day. Upon comple- tion, the refinery will have the capability of providing the Las Vegas market with refined products through the UNEV Pipeline, as well as serving our traditional Salt Lake City and other markets across the Inter-Mountain West. We are on track to complete the expansion in the fourth quarter of 2015. • El Dorado Naphtha Fractionation: Our ongoing work at our El Dorado Refinery, in El Dorado, Kansas, will improve liquid yields by reducing byproducts such as fuel gas, propane and butane and reduce the benzene content of our gasoline pool lower. We are on track for completion in the spring of 2015. • Tulsa Refinery Modernization: In 2014, we filed a permit to encompass the full 170,000 barrels per day of crude distilla- tion capacity at our Tulsa Refinery providing flexibility for future improvement projects. Currently, plans are underway to modernize the fluid catalytic cracking unit (FCCU) includ- ing the installation of updated feed nozzles, an upgraded catalyst stripper and riser termination device. The investments being made will increase FCC capacity by 4,000 barrels per day and improve conversion rates from heavy oils to gasoline and diesel a further 1%. We are on track to complete the FCC modernization project in the first quarter of 2016. • Holly Energy Partners’ Crude Gathering System Expansion: In 2014, Holly Energy Partners completed the expansion of 800 miles of pipeline in southeastern New Mexico. The expanded gathering system has capacity up to 100,000 barrels per day and provides additional delivery capacity to our Navajo Refinery while also connecting to major clearing points in Cushing, Oklahoma, Midland, Texas and Crane, Texas. In addition to these initiatives, we announced the appointment of George Damiris to serve as our new Chief Operating Officer in 2014. George has been a key member for the leadership team since joining the Company in 2007 and has more than 25 years of refining industry experience. We look forward to benefiting from his leadership as we continue to improve operational reliability and safety while also completing our slate of strategic growth projects. COMMITTED TO THE ENVIRONMENT, HEALTH, SAFETY AND OUR COMMUNITIES HollyFrontier Corporation’s core values are health, safety, corporate citizenship and environmental stewardship. We are actively investing to reduce the environmental impact of our operations. Emissions at the Woods Cross Refinery are being reduced through new investments despite a 50% increase in plant capacity. We have invested to reduce our water needs, bringing our usage to half the industry average and have an active campaign upgrading fired heaters and boilers across our refineries to reduce our carbon dioxide emissions. At HollyFrontier, we consider the communities we operate in as a part of our extended family and are committed to promoting sustainable social and economic benefits in the areas we oper- ate. We endeavor to give back both through volunteerism and charitable giving to improve the lives of those who share the community where our employees live and work. Finally, we are dedicated to providing the American consumer with a secure supply of affordable transportation fuel produced in a safe and environmentally responsible manner. In 2014, both the Tulsa and Woods Cross Refineries received the American Fuel and Petrochemical Manufacturers Association’s Meritorious Safety Performance Award. We are appreciative for the service and dedication of all of HollyFrontier’s 2,686 employees who work hard every day to ensure our business operations are conducted safely and reliably. Sincerely, MICHAEL C. JENNINGS Chairman, Chief Executive Officer and President 3 FINANCIAL HIGHLIGHTS YEAR ENDED DECEMBER 31 2013 2014 Sales and other revenues Income before income taxes Net income attributable to HFC stockholders Net income per common share attributable to HFC stockholders – diluted Cash flows from operating activities Cash flows used for capital expenditures Total assets HFC stockholders’ equity Sales of refined products – barrels per day (“BPD”) Refinery production – BPD Employees $ 20,160,560,000 $ 19,764,327,000 $ $ $ $ $ 1,159,399,000 735,842,000 3.64 869,174,000 425,127,000 $ $ $ $ $ 467,500,000 281,292,000 1.42 758,596,000 564,821,000 $ 10,056,739,000 $ 9,230,640,000 $ 5,999,620,000 $ 5,523,584,000 446,390 413,820 2,662 461,640 425,010 2,686 7 2 7 , 1 3 2 0 , 1 6 3 7 1 8 2 4 0 1 3 6 6 , 1 8 3 3 , 1 9 6 8 9 5 7 3 8 2 1 9 0 0 2 , 1 6 1 , 0 2 4 6 7 9 1 , 0 4 4 , 5 1 3 2 3 , 8 10 11 12 13 14 10 11 12 13 14 10 11 12 13 14 Net Income Attributable to HFC Stockholders $ in millions Cash Flows from Operating Activities $ in millions Revenues $ in millions 3 4 4 4 1 4 5 2 4 2 3 3 6 2 2 3 5 0 6 , 0 0 0 6 , 4 2 5 , 5 4 0 2 , 5 9 2 3 0 1 , 7 5 0 0 1 , 6 7 5 , 9 1 3 2 , 9 7 9 6 0 5 0 3 , 10 11 12 13 14 10 11 12 13 14 10 11 12 13 14 Refinery Production BPD in thousands HFC Stockholders’ Equity $ in millions Total Assets $ in millions 4 HollyFrontier Corporation 2014 Annual Report UNITED STATES SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 _________________________________________________________________ FORM 10-K _________________________________________________________________ (Mark One) ANNUAL REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 TRANSITION REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 For the fiscal year ended December 31, 2014 OR For the transition period from __________ to ____________ Commission File Number 1-3876 _________________________________________________________________ HOLLYFRONTIER CORPORATION (Exact name of registrant as specified in its charter) _________________________________________________________________ Delaware (State or other jurisdiction of incorporation or organization) 2828 N.

The hydrogen produced from the reforming process is used to desulfurize other refinery oils and is a primary source of hydrogen for the refinery. “Cracking” means the process of breaking down larger, heavier and more complex hydrocarbon molecules into simpler and lighter molecules. “Crude oil distillation” means the process of distilling vapor from liquid crudes, usually by heating, and condensing the vapor slightly above atmospheric pressure turning it back to liquid in order to purify, fractionate or form the desired products. “Ethanol” means a high octane gasoline blend stock that is used to make various grades of gasoline. “FCC,” or fluid catalytic cracking, means a refinery process that breaks down large complex hydrocarbon molecules into smaller more useful ones using a circulating bed of catalyst at relatively high temperatures. “Hydrodesulfurization” means to remove sulfur and nitrogen compounds from oil or gas in the presence of hydrogen and a catalyst at relatively high temperatures. “Hydrogen plant” means a refinery unit that converts natural gas and steam to high purity hydrogen, which is then used in the hydrodesulfurization, hydrocracking and isomerization processes. “HF alkylation” or hydrofluoric alkylation, means a refinery process which combines isobutane and C3/C4 olefins using HF acid as a catalyst to make high octane gasoline blend stock. “Isomerization” means a refinery process for rearranging the structure of C5/C6 molecules without changing their size or chemical composition and is used to improve the octane of C5/C6 gasoline blendstocks. “LPG” means liquid petroleum gases. “Lubricant” or “lube” means a solvent neutral paraffinic product used in commercial heavy duty engine oils, passenger car oils and specialty products for industrial applications such as heat transfer, metalworking, rubber and other general process oil. “MSAT2” means Control of Hazardous Air Pollutants from Mobile Sources, a rule issued by the U.S. Environmental Protection Agency to reduce hazardous emissions from motor vehicles and motor vehicle fuels. “MEK” means a lube process that separates waxy oil from non-waxy oils using methyl ethyl ketone as a solvent. “MMBTU” means one million British thermal units. 4 Table of Content “Natural gasoline” means a low octane gasoline blend stock that is purchased and used to blend with other high octane stocks produced to make various grades of gasoline. “Paraffinic oil” is a high paraffinic, high gravity oil produced by extracting aromatic oils and waxes from gas oil and is used in producing high-grade lubricating oils. “Refinery gross margin” means the difference between average net sales price and average product costs per produced barrel of refined products sold. This does not include the associated depreciation and amortization costs. “Reforming” means the process of converting gasoline type molecules into aromatic, higher octane gasoline blend stocks while producing hydrogen in the process. “Roofing flux” is produced from the bottom cut of crude oil and is the base oil used to make roofing shingles for the housing industry. “ROSE,” or “Solvent deasphalter / residuum oil supercritical extraction,” means a refinery unit that uses a light hydrocarbon like propane or butane to extract non-asphaltene heavy oils from asphalt or atmospheric reduced crude. These deasphalted oils are then further converted to gasoline and diesel in the FCC process. The remaining asphaltenes are either sold, blended to fuel oil or blended with other asphalt as a hardener. “Scanfiner” is a refinery unit that removes sulfur from gasoline to produce low sulfur gasoline blendstock. “Sour crude oil” means crude oil containing quantities of sulfur greater than 0.4 percent by weight, while “sweet crude oil” means crude oil containing quantities of sulfur equal to or less than 0.4 percent by weight. “Vacuum distillation” means the process of distilling vapor from liquid crudes, usually by heating, and condensing the vapor below atmospheric pressure turning it back to a liquid in order to purify, fractionate or form the desired products. “WCS” means Western Canada Select crude oil and is made up of Canadian heavy conventional and bitumen crude oils blended with sweet synthetic and condensate diluents. “WTI” means West Texas Intermediate and is a grade of crude oil used as a common benchmark in oil pricing. WTI is a sweet crude oil and has a relatively low density. “WTS” means West Texas Sour, a medium sour crude oil. 5 Table of Content Items 1 and 2.

Markets and Competition The primary markets for the El Dorado Refinery's refined products are Colorado and the Plains States, which include the Kansas City metropolitan area. The gasoline, diesel and jet fuel produced by the El Dorado Refinery are primarily shipped via pipeline to terminals for distribution by truck or rail. We ship product via the NuStar Pipeline Operating Partnership L.P. Pipeline to the northern Plains States, via the Magellan Pipeline Company, L.P. (“Magellan”) mountain pipeline to Denver, Colorado, and on the Magellan mid-continent pipeline to the Plains States. 9 Table of Content The El Dorado Refinery faces competition from other Plains States and Mid-Continent refiners, but the principal competitors for the El Dorado Refinery are Gulf Coast refiners. Our Gulf Coast competitors typically have lower production costs due to greater economies of scale; however, they incur higher refined product transportation costs, which allows the El Dorado Refinery to compete effectively in the Plains States and Rocky Mountain region with Gulf Coast refineries. For the year ended December 31, 2014, sales to Shell Oil represented approximately 22% of the El Dorado Refinery's total sales and 11% of our total consolidated sales. We have an offtake agreement with an affiliate of Shell Oil under which Shell Oil purchases gasoline, diesel and jet fuel production of the El Dorado Refinery at market-based prices through October 2015 primarily to support its branded and unbranded marketing network. We market gasoline and diesel primarily in Denver and throughout the Plains States. The Tulsa Refineries serve the Mid-Continent region of the United States. Distillates and gasolines are primarily delivered from the Tulsa Refineries to market via pipelines owned and operated by Magellan. These pipelines connect the refinery to distribution channels throughout Colorado, Oklahoma, Kansas, Missouri, Illinois, Iowa, Minnesota, Nebraska and Arkansas. Additionally, HEP's on-site truck and rail racks facilitate access to local refined product markets. We have an offtake agreement through November 2019 with an affiliate of Sinclair whereby Sinclair purchases 45,000 to 50,000 BPD of gasoline and distillate products at market prices from us to supply its branded and unbranded marketing network throughout the Midwest. Upon expiration, the offtake agreement can be renewed by Sinclair for an additional five-year term. For the year ended December 31, 2014, sales to Sinclair represented approximately 30% of the Tulsa Refineries' total sales and 10% of our total consolidated sales. The Tulsa Refineries' principal customers for conventional gasoline include Sinclair, other refiners, convenience store chains, independent marketers and retailers. Sinclair, truck stop operators and railroads are the primary diesel customers. Jet fuel is sold primarily for commercial use. The refinery's asphalt and roofing flux products are sold via truck or railcar directly from the refineries or to customers throughout the Mid-Continent region primarily to paving contractors and manufacturers of roofing products. Our Tulsa West facility also produces specialty lubricant products sold in both commercial and specialty markets throughout North America and to customers with operations in Central America and South America. The specialty lubricant products are high-value products that provide a significantly higher margin contribution to the refinery. Base oil customers include blender-compounders who prepare the various finished lubricant and grease products sold to end users. Agricultural products are formulated as supplemental carriers for herbicides and as Environmental Protection Agency (“EPA”) registered pesticide oils, are sold to product formulators. Process oil customers include rubber and chemical industry customers. Specialty waxes are sold primarily to packaging customers as coating material for paper and cardboard, and to non-packaging customers in the construction materials, adhesive and candle-making markets. Our production represents approximately 6% of paraffinic oil capacity and 13% of wax production capacity in the United States market and is one of four refineries of specialty aromatic oils in North America.

Supporting Infrastructure includes approximately 1.5 million barrels of feedstock and product tankage, of which 0.2 million barrels of tankage are owned by HEP. The facility typically processes or blends an additional 2,000 BPSD of natural gasoline, butane and gas oil over its 31,000 BPSD capacity. We own and operate 4 miles of hydrogen pipeline that connects the Woods Cross Refinery to a hydrogen plant located on the property of Chevron's Salt Lake City Refinery. Additionally, HEP owns and operates 12 miles of crude oil and refined products pipelines that allows us to connect our Woods Cross Refinery to common carrier pipeline systems. Engineering and construction continue on our previously announced expansion project to increase planned processing capacity to 45,000 BPSD at a cost currently expected to range between $350.0 million and $400.0 million. The expansion is expected to be completed in the fourth quarter of 2015. This project work includes a new rail loading rack for intermediates and finished products associated with refining waxy crude oil. Further discussion of this project can be found in “Management's Discussion and Analysis of Financial Condition and Results of Operations” under Liquidity and Capital Resources. In conjunction with the expansion, we signed a 10-year, 20,000 BPD crude oil supply agreement with Newfield Exploration Company. This agreement, which commences upon completion of the expansion, will supply black and yellow wax crude oil produced in the nearby Uinta Basin to the Woods Cross Refinery. Upon completion of this expansion, the Woods Cross Refinery's capacity to process waxy crude is expected to double to approximately 24,000 BPD. Markets and Competition The Cheyenne Refinery primarily markets its products in eastern Colorado, including metropolitan Denver, eastern Wyoming and western Nebraska. Because of the location of the Cheyenne Refinery, we are able to sell a significant portion of its diesel directly from the truck rack at the refinery, therefore, eliminating transportation costs. The Cheyenne Refinery ships refined products via the Magellan pipeline serving Denver and Colorado Springs, Colorado. Denver Market The most competitive market for the Cheyenne Refinery is the Denver metropolitan area. Three other refineries supply the Denver market: Wyoming refineries near Rawlins and in Casper owned by Sinclair and a refinery in Denver owned by Suncor. Five product pipelines also supply Denver, including three from outside the region. Utah Market The Woods Cross Refinery's primary market is Utah, which is currently supplied by a number of local refiners and the Pioneer Pipeline. In addition to our Woods Cross Refinery, local area refiners include Chevron, Tesoro, Big West and Silver Eagle. Other refiners that ship into the Woods Cross market via the Pioneer Pipeline include Sinclair, ExxonMobil, CHS and Phillips 66. We estimate the four local refineries that compete with our Woods Cross Refinery have a combined capacity to process approximately 150,000 BPD of crude oil. The five Utah refineries collectively supply an estimated 70% of the gasoline and distillate products consumed in the states of Utah and Idaho, with the remainder imported from refineries in Wyoming and Montana via the Pioneer Pipeline owned jointly by Sinclair and Phillips 66. Approximately 40% - 45% of the gasoline and diesel fuel produced by our Woods Cross Refinery is sold through a network of Phillips 66 branded marketers under a long-term supply agreement. Idaho, Wyoming, Eastern Washington and Nevada Markets We supply a small percentage of the refined products consumed in the combined Idaho, Wyoming, eastern Washington and Nevada markets. Our Woods Cross Refinery ships refined products over a common carrier pipeline system owned by Tesoro Logistics Northwest Pipelines LLC (“Tesoro Logistics”) to numerous terminals, including HEP's terminal at Spokane, Washington and to terminals at Pocatello and Boise, Idaho and Pasco, Washington that are owned by Tesoro Logistics. We sell to branded and unbranded customers in these markets. In 2012, we began shipping refined products to Cedar City, Utah and Las Vegas, Nevada via the UNEV Pipeline. The majority of the Las Vegas, Nevada market for refined products is supplied by various West Coast refiners and suppliers via Kinder Morgan's CalNev common carrier pipeline system. Principal Products Set forth below is information regarding the principal products produced at our Cheyenne and Woods Cross Refineries: 14 Table of Content Rocky Mountain Region (Cheyenne and Woods Cross Refineries) Sales of produced refined products: Gasolines Diesel fuels Jet fuels Fuel oil Asphalt LPG and other Total Years Ended December 31, 2013 2012 2014 56% 33% —% 1% 5% 5% 100% 56% 30% 1% 1% 5% 7% 100% 55% 32% —% 2% 5% 6% 100% Crude Oil and Feedstock Supplies Crude oil is transported to the Cheyenne Refinery from suppliers in Canada, Colorado, Nebraska, North Dakota and Montana via common carrier pipelines owned by Kinder Morgan, Plains and Suncor Energy, as well as by truck. The Woods Cross Refinery currently obtains crude oil from suppliers in Canada, Wyoming, Utah and Colorado as delivered via common carrier pipelines that originate in Canada, Wyoming and Colorado. We also receive crude oil via the SLC Pipeline, a joint venture common carrier pipeline in which HEP owns a 25% interest. Supplies of black wax crude oil are shipped via truck. NK Asphalt Partners We manufacture commodity and modified asphalt products at our manufacturing facilities located in Glendale, Arizona; Albuquerque, New Mexico; Artesia, New Mexico and Catoosa, Oklahoma. Our Albuquerque and Artesia facilities manufacture modified hot asphalt products and commodity emulsions from base asphalt materials provided by our refineries and third-party suppliers. Our Glendale facility manufactures modified hot asphalt products from base asphalt materials provided by our refineries and third-party suppliers. Our Catoosa facility manufactures specialty modified asphalt and commodity asphalt products. We market these asphalt products in Arizona, New Mexico, Oklahoma, Kansas, Missouri, Texas and northern Mexico. Our products are shipped via third-party trucking companies to commercial customers that provide asphalt based materials for commercial and government projects. Other Assets We own a 50% joint venture interest in Sabine Biofuels, a 30 million gallon per year biodiesel production facility located near Port Arthur, Texas. HOLLY ENERGY PARTNERS, L.P. HEP is a Delaware limited partnership that trades on the New York Stock Exchange under the trading symbol “HEP.” HEP was formed to acquire, own and operate substantially all of the refined product pipeline and terminalling assets that support our refining and marketing operations in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. HEP generates revenues by charging tariffs for transporting petroleum products and crude oil through its pipelines, by leasing certain pipeline capacity to Alon, by charging fees for terminalling refined products and other hydrocarbons and by storing and providing other services at its storage tanks and terminals. HEP does not take ownership of products that it transports or terminals; therefore, it is not directly exposed to changes in commodity prices. HEP's recent acquisitions (2010 through present) are summarized below: UNEV Interest Transaction On July 12, 2012, HEP acquired from us our 75% interest in UNEV. We received consideration consisting of $260.0 million in cash and 1.0 million HEP common units. UNEV owns the UNEV Pipeline, a 12-inch refined products pipeline running from Salt Lake City, Utah to Las Vegas, Nevada together with terminal facilities in Cedar City, Utah and North Las Vegas. The UNEV Pipeline was completed in late 2011 and became operational during the first quarter of 2012. 15 Table of Content Legacy Frontier Pipeline and Tankage Asset Transaction On November 9, 2011, HEP acquired from us certain tankage, loading rack and crude receiving assets located at our El Dorado and Cheyenne Refineries. We received non-cash consideration consisting of promissory notes with an aggregate principal amount of $150.0 million and 3.8 million HEP common units. Tulsa East / Lovington Storage Asset Transaction On March 31, 2010, HEP acquired from us certain storage assets for $93.0 million, consisting of hydrocarbon storage tanks having approximately 2.0 million barrels of storage capacity, a rail loading rack and a truck unloading rack located at our Tulsa East facility and an asphalt loading rack facility located at our Navajo Refinery facility located in Lovington, New Mexico. Transportation Agreements Agreements with HEP HEP serves our refineries under long-term pipeline and terminal, tankage and throughput agreements expiring in 2019 through 2026. Under these agreements, we pay HEP fees to transport, store and throughput volumes of refined product and crude oil on HEP's pipeline and terminal, tankage and loading rack facilities that result in minimum annual payments to HEP including UNEV (a consolidated subsidiary of HEP). Under these agreements, the agreed upon tariff rates are subject to annual tariff rate adjustments on July 1 at a rate based upon the percentage change in Producer Price Index (“PPI”) or Federal Energy Regulatory Commission index. As of December 31, 2014, these agreements result in minimum annualized payments to HEP of $231.6 million. Since HEP is a consolidated entity, our transactions with HEP including the transactions discussed above and fees paid under our transportation agreements with HEP and UNEV, a consolidated subsidiary of HEP, are eliminated and have no impact on our consolidated financial statements. Agreement with Alon HEP has a 15-year pipelines and terminals agreement with Alon expiring in 2020, under which Alon has agreed to transport on HEP's pipelines and throughput through its terminals, volumes of refined products that results in a minimum level of annual revenue. The agreed upon tariff rates are increased or decreased annually at a rate equal to the percentage change in PPI, but will not decrease below the initial tariff rate. Also, HEP has a capacity lease agreement with Alon under which Alon leases space on HEP's Orla to El Paso pipeline for the shipment of up to 15,000 barrels of refined product per day. The terms under this agreement expire in 2018 through 2022. As of December 31, 2014, HEP's assets include: Pipelines • approximately 810 miles of refined product pipelines, including 340 miles of leased pipelines, that transport gasoline, diesel and jet fuel principally from our Navajo Refinery in New Mexico to our customers in the metropolitan and rural areas of Texas, New Mexico, Arizona, Colorado, Utah and northern Mexico; approximately 510 miles of refined product pipelines that transport refined products from Alon's Big Spring refinery in Texas to its customers in Texas and Oklahoma; three 65-mile pipelines that transport intermediate feedstocks and crude oil from our Navajo Refinery crude oil distillation and vacuum facilities in Lovington, New Mexico to our petroleum refinery facilities in Artesia, New Mexico; approximately 910 miles of crude oil trunk, gathering and connection pipelines located in west Texas, New Mexico and Oklahoma that deliver crude oil to our Navajo Refinery; approximately 8 miles of refined product pipelines that support our Woods Cross Refinery located near Salt Lake City, Utah; gasoline and diesel connecting pipelines that support our Tulsa East facility; five intermediate product and gas pipelines between the Tulsa East and Tulsa West facilities; and crude receiving assets located at our Cheyenne Refinery. • • • • • • • Refined Product Terminals and Refinery Tankage • • • four refined product terminals located in El Paso, Texas; Moriarty and Bloomfield, New Mexico; and Tucson, Arizona, with an aggregate capacity of approximately 1,200,000 barrels, that are integrated with HEP's refined product pipeline system that serves our Navajo Refinery; one refined product terminal located in Spokane, Washington, with a capacity of approximately 400,000 barrels, that serves third-party common carrier pipelines; one refined product terminal near Mountain Home, Idaho, with a capacity of 120,000 barrels, that serves a nearby United States Air Force Base; 16 Table of Content • • • • two refined product terminals, located in Wichita Falls and Abilene, Texas, and one tank farm in Orla, Texas with aggregate capacity of approximately 500,000 barrels, that are integrated with HEP's refined product pipelines that serve Alon's Big Spring, Texas refinery; a refined product loading rack facility at each of our El Dorado, Tulsa, Navajo, Cheyenne and Woods Cross Refineries, heavy product / asphalt loading rack facilities at our Tulsa East facility, Navajo Refinery Lovington facility and Cheyenne Refinery, LPG loading rack facilities at our El Dorado Refinery, Tulsa West facility and Cheyenne Refinery, lube oil loading racks at our Tulsa West facility and crude oil Leased Automatic Custody Transfer units located at our Cheyenne Refinery; on-site crude oil tankage at our Tulsa, Navajo, Cheyenne and Woods Cross Refineries having an aggregate storage capacity of approximately 1,300,000 barrels; and on-site refined and intermediate product tankage at our El Dorado, Tulsa and Cheyenne Refineries having an aggregate storage capacity of approximately 8,100,000 barrels. Additionally, HEP owns a 75% interest in UNEV, which owns the UNEV Pipeline, a 12-inch refined products pipeline from Salt Lake City, Utah to Las Vegas, Nevada together with terminal facilities in the Cedar City, Utah and North Las Vegas areas, and a 25% interest in SLC Pipeline LLC, which owns a 95-mile intrastate pipeline system that serves refineries in the Salt Lake City area. ADDITIONAL OPERATIONS AND OTHER INFORMATION Corporate Offices We lease approximately 60,000 square feet for our principal corporate offices in Dallas, Texas. The lease for our principal corporate offices expires in 2021. Functions performed in the Dallas office include overall corporate management, refinery and HEP management, planning and strategy, corporate finance, crude acquisition, logistics, contract administration, marketing, investor relations, governmental affairs, accounting, tax, treasury, information technology, legal and human resources support functions. Employees and Labor Relations As of December 31, 2014, we had 2,686 employees, of which 899 are currently covered by collective bargaining agreements having various expiration dates between 2015 and 2018. We consider our employee relations to be good. In early February 2015, we received communications from the United Steelworkers Union representing employees at our El Dorado and Woods Cross Refineries of its intention to commence a work stoppage in early May 2015 and could receive a similar communication from the United Steelworkers Union representing employees at our Cheyenne Refinery. We have plans allowing for the continued operations of all three refineries in the event the union does commence a work stoppage and believe such plans are adequate to allow continued operations of all three refineries. Regulation Refinery and pipeline operations are subject to numerous federal, state and local laws regulating the discharge of substances into the environment or otherwise relating to the protection of the environment. Permits or other authorizations are required under these laws for the operation of our refineries, pipelines and related facilities, and these permits and authorizations are subject to revocation, modification and renewal. Over the years, there have been ongoing communications, including notices of violations, about environmental matters between us and federal and state authorities, some of which have resulted or will result in changes to operating procedures and in capital expenditures. Compliance with applicable environmental laws, regulations and permits will continue to have an impact on our operations, the results of our operations, and our capital requirements. We believe that our current operations are in substantial compliance with applicable federal, state, and local environmental laws, regulations, and permits. 17 Table of Content Our operations and many of the products we manufacture are subject to certain requirements of the Federal Clean Air Act (“CAA”) as well as related state and local laws and regulations. Certain CAA regulatory programs applicable to our refineries require capital expenditures for the installation of certain air pollution control devices. Additionally, the EPA has the authority under the CAA to modify the formulation of the refined transportation fuel products we manufacture in order to limit the emissions associated with their final use. In addition, in 2014, the EPA published a proposed rule that proposes amendments to two refinery standards already in effect: the National Emission Standards for Hazardous Air Pollutants (“NESHAP”) from Petroleum Refineries and the NESHAP for Petroleum Refineries: Catalytic Cracking Units, Catalytic Reforming Units and Sulfur Recovery Units. The proposed rule would also amend emission requirements under the existing Petroleum Refinery New Source Performance Standard. Collectively, these proposed amendments would, among other things, require monitoring of air concentrations of benzene around the fenceline perimeter of refineries to assure that emissions are controlled and these results would be available to the public. The proposed amendments could also require upgraded emission controls for storage tanks and flares. These new proposals, as well as subsequent rulemaking under the CAA or similar laws, or new agency interpretations of existing laws and regulations, may necessitate additional expenditures in future years. Also, we are subject to the EPA's Control of Hazardous Air Pollutants from Mobile Sources (“MSAT2”) regulations that impose reductions in the benzene content of our produced gasoline. Our refineries currently purchase a portion of their benzene credits to meet these requirements. If economically justified, we could implement additional benzene reduction projects to eliminate the need to purchase benzene credits. The Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007 prescribe certain percentages of renewable fuels (e.g., ethanol and biofuels) that, where required, must be blended into our produced gasoline and diesel. Additional changes in fuel standards, called Tier 3 standards, to reduce vehicle emissions were finalized in 2014. These new requirements, other requirements of the CAA, and other presently existing or future environmental regulations may cause us to make substantial capital expenditures and purchase credits at significant cost to enable our refineries to produce products that meet applicable requirements. Further regulatory requirements have emerged from concerns over the potential climate impacts of certain "greenhouse gases" such as carbon dioxide and methane. In response to a statutory directive, the EPA has promulgated rules requiring the reporting of greenhouse gas emissions. In 2010, the EPA promulgated regulations applying construction and operating permit requirements under the CAA's Prevention of Significant Deterioration and Title V programs to sources with potential greenhouse gas emissions above certain threshold levels. The EPA has also announced its intention to issue a New Source Performance Standard directly regulating greenhouse gas emissions from refineries, although recent statements from EPA Administrator McCarthy indicate that issuance of such Performance Standard is not imminent. Proposals both expanding and limiting the EPA's authority in this area continue to be considered in Congress. Litigation challenging the EPA's authority over greenhouse gas emissions also is pending in federal court. Our operations are also subject to the Federal Clean Water Act (“CWA”), the Federal Safe Drinking Water Act (“SDWA”) and comparable state and local requirements. The CWA, the SDWA and analogous laws prohibit any discharge into surface waters, ground waters, injection wells and publicly-owned treatment works except in conformance with legal authorization, such as pre- treatment permits and National Pollutant Discharge Elimination System (“NPDES”) permits, issued by federal, state and local governmental agencies. NPDES permits and analogous water discharge permits are valid for a maximum of five years and must be renewed. In 2014, the EPA, in conjunction with the Army Corps of Engineers, issued a proposed rule to define 'waters of the U.S.,' which could expand the regulatory reach of the existing clean water regulations. Finalizing this proposed rule, along with other regulatory activities the EPA is discussing, may necessitate additional expenditures in future years. We generate wastes that may be subject to the Resource Conservation and Recovery Act and comparable state and local requirements. The EPA and various state agencies have limited the approved methods of disposal for certain hazardous and non- hazardous wastes. The EPA is currently working on several rulemakings that could impact how our refineries manage various waste streams. While these rulemakings are still in development, it does not appear that these rules will significantly impact our refineries. 18 Table of Content The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), also known as “Superfund,” imposes liability, without regard to fault or the legality of the original conduct, on certain classes of persons, including the current and past owner or operator of the disposal site or sites from which there is a release of a “hazardous substance,” as well as persons that disposed of or arranged for the disposal or treatment of the hazardous substances at the site or sites. Under CERCLA, such persons may be subject to joint and several liability for such costs as the cost of cleaning up the hazardous substances that have been released into the environment and for damages to natural resources. In the course of our historical operations, as well as in our current normal operations, we have generated waste, some of which falls within the statutory definition of a “hazardous substance” and some of which may have been disposed of at sites that may be subject to cleanup and cost recovery actions under CERCLA by a government entity or other third party. Similarly, locations now owned or operated by us, where third parties have disposed such hazardous substances in the past, may also be subject to cleanup and cost recovery actions under CERCLA. Under CERCLA, liable parties may seek contribution from other liable parties to share in the costs of cleanup. Some states have enacted laws similar to CERCLA which impose similar responsibilities and liabilities on responsible parties. It is also not uncommon for neighboring landowners and other third parties to file claims under state law for personal injury and property damage allegedly caused by hazardous substances or other pollutants released into the environment. As is the case with all companies engaged in industries similar to ours, we face potential exposure to future claims and lawsuits involving environmental matters. These matters include soil and water contamination, air pollution, personal injury and property damage allegedly caused by substances that we manufactured, handled, used, released or disposed of. We currently have environmental remediation projects that relate to recovery, treatment and monitoring activities resulting from past releases of refined product and crude oil into the environment. As of December 31, 2014, we had an accrual of $104.5 million related to such environmental liabilities. We are and have been the subject of various state, federal and private proceedings and inquiries relating to compliance with environmental regulations and conditions, including those discussed above. Compliance with current and future environmental regulations is expected to require additional expenditures, including expenditures for investigation and remediation, which may be significant, at our refineries and at pipeline transportation facilities. To the extent that future expenditures for these purposes are material and can be reasonably determined, these costs are disclosed and accrued, if applicable. Our operations are also subject to various laws and regulations relating to occupational health and safety. We maintain safety, training and maintenance programs as part of our ongoing efforts to ensure compliance with applicable laws and regulations. Compliance with applicable health and safety laws and regulations has required and continues to require substantial expenditures. Health and environmental legislation and regulations change frequently. We cannot predict what additional health and environmental legislation or regulations will be enacted or become effective in the future or how existing or future laws or regulations will be administered or interpreted with respect to our operations. Compliance with more stringent laws or regulations or adverse changes in the interpretation of existing laws or regulations by government agencies could have an adverse effect on our financial position and the results of our operations and could require substantial expenditures for the installation and operation of systems and equipment that we do not currently possess. Insurance Our operations are subject to hazards of operations, including fire, explosion and weather-related perils. We maintain various insurance coverages, including business interruption insurance, subject to certain deductibles. We are not fully insured against certain risks because such risks are not fully insurable, coverage is unavailable, or premium costs, in our judgment, do not justify such expenditures. We have a risk management oversight committee that is made up of members from our senior management. This committee oversees our risk enterprise program, monitors our risk environment and provides direction for activities to mitigate identified risks that may adversely affect the achievement of our goals. 19 Table of Content Item 1A. Risk Factors Investing in us involves a degree of risk, including the risks described below. Our operating results have been, and will continue to be, affected by a wide variety of risk factors, many of which are beyond our control, that could have adverse effects on profitability during any particular period. You should carefully consider the following risk factors together with all of the other information included in this Annual Report on Form 10-K, including the financial statements and related notes, when deciding to invest in us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business operations. If any of the following risks were to actually occur, our business, financial condition or results of operations could be materially and adversely affected. The headings provided in this Item 1A. are for convenience and reference purposes only and shall not affect or limit the extent or interpretation of the risk factors. The prices of crude oil and refined products materially affect our profitability, and are dependent upon many factors that are beyond our control, including general market demand and economic conditions, seasonal and weather-related factors, regional and grade differentials and governmental regulations and policies. Among these factors is the demand for crude oil and refined products, which is largely driven by the conditions of local and worldwide economies as well as by weather patterns and the taxation of these products relative to other energy sources. Governmental regulations and policies, particularly in the areas of taxation, energy and the environment, also have a significant impact on our activities. Operating results can be affected by these industry factors, product and crude pipeline capacities, changes in transportation costs, accidents or interruptions in transportation, competition in the particular geographic areas that we serve, and factors that are specific to us, such as the success of particular marketing programs and the efficiency of our refinery operations. The demand for crude oil and refined products can also be reduced due to a local or national recession or other adverse economic condition that results in lower spending by businesses and consumers on gasoline and diesel fuel, higher gasoline prices due to higher crude oil prices, a shift by consumers to more fuel-efficient vehicles or alternative fuel vehicles (such as ethanol or wider adoption of gas/electric hybrid vehicles), or an increase in vehicle fuel economy, whether as a result of technological advances by manufacturers, legislation mandating or encouraging higher fuel economy or the use of alternative fuel. We do not produce crude oil and must purchase all our crude oil, the price of which fluctuates based upon worldwide and local market conditions. Our profitability depends largely on the spread between market prices for refined petroleum products and crude oil prices. This margin is continually changing and may fluctuate significantly from time to time. Crude oil and refined products are commodities whose price levels are determined by market forces beyond our control. For example, the reversal of certain existing pipelines or the construction of certain new pipelines transporting additional crude oil or refined products to markets that serve competing refineries could affect the market dynamic that has allowed us to take advantage of favorable pricing. Additionally, due to the seasonality of refined products markets and refinery maintenance schedules, results of operations for any particular quarter of a fiscal year are not necessarily indicative of results for the full year and can vary year to year in the event of unseasonably cool weather in the summer months and / or unseasonably warm weather in the winter months in the markets in which we sell our petroleum products. In general, prices for refined products are influenced by the price of crude oil. Although an increase or decrease in the price for crude oil may result in a similar increase or decrease in prices for refined products, there may be a time lag in the realization of the similar increase or decrease in prices for refined products. The effect of changes in crude oil prices on operating results therefore depends in part on how quickly refined product prices adjust to reflect these changes. A substantial or prolonged increase in crude oil prices without a corresponding increase in refined product prices, a substantial or prolonged decrease in refined product prices without a corresponding decrease in crude oil prices, or a substantial or prolonged decrease in demand for refined products could have a significant negative effect on our earnings and cash flow. Also, crude oil supply contracts are generally short-term contracts with market-responsive pricing provisions. We purchase our refinery feedstocks weeks before manufacturing and selling the refined products. Price level changes during the period between purchasing feedstocks and selling the manufactured refined products from these feedstocks could have a significant effect on our financial condition and results of operations. Also, our crude oil and refined products inventories are valued at the lower of cost or market under the last-in, first-out (“LIFO”) inventory valuation methodology. If the market value of our inventory were to decline to an amount less than our LIFO cost, we would record a write-down of inventory and a non-cash charge to cost of products sold even when there is no underlying economic impact at that point in time. For example, for the year ended December 31, 2014, we recorded a non-cash increase to cost of products sold in the amount of $397.5 million. Continued volatility in crude oil and refined products prices could result in additional lower of cost or market inventory charges in the future, or in reversals reducing cost of products sold in subsequent periods should prices recover. 20 Table of Content A material decrease in the supply of crude oil available to our refineries could significantly reduce our production levels. To maintain or increase production levels at our refineries, we must continually contract for crude oil supplies from third parties. A material decrease in crude oil production from the fields that supply our refineries, as a result of depressed commodity prices, lack of drilling activity, natural production declines or otherwise, could result in a decline in the volume of crude oil available to our refineries. In addition, any prolonged disruption of a significant pipeline that is used in supplying crude oil to our refineries or the potential operation of a new, converted or expanded crude oil pipeline that transports crude oil to other markets could result in a decline in the volume of crude oil available to our refineries. Such an event could result in an overall decline in volumes of refined products processed at our refineries and therefore a corresponding reduction in our cash flow. In addition, the future growth of our operations will depend in part upon whether we can contract for additional supplies of crude oil at a greater rate than the rate of natural decline in our currently connected supplies. If we are unable to secure additional crude oil supplies of sufficient quality or crude pipeline expansion to our refineries, we will be unable to take full advantage of current and future expansion of our refineries' production capacities. We may not be able to successfully execute our business strategies to grow our business. Further, if we are unable to complete capital projects at their expected costs or in a timely manner, if we are unsuccessful in integrating the operations of assets we acquire, or if the market conditions assumed in our project economics deteriorate, our financial condition, results of operations, or cash flows could be materially and adversely affected. One of the ways we may grow our business is through the construction of new refinery processing units (or the purchase and refurbishment of used units from another refinery) and the expansion of existing ones. Projects are generally initiated to increase the yields of higher-value products, increase the amount of lower cost crude oils that can be processed, increase refinery production capacity, meet new governmental requirements, or maintain the operations of our existing assets. Additionally, our growth strategy includes projects that permit access to new and/or more profitable markets. The construction process involves numerous regulatory, environmental, political, and legal uncertainties, most of which are not fully within our control, including: • • • • • denial or delay in issuing requisite regulatory approvals and/or permits; compliance with or liability under environmental regulations; unplanned increases in the cost of construction materials or labor; disruptions in transportation of modular components and/or construction materials; severe adverse weather conditions, natural disasters, or other events (such as equipment malfunctions, explosions, fires, spills) affecting our facilities, or those of vendors and suppliers; shortages of sufficiently skilled labor, or labor disagreements resulting in unplanned work stoppages; • • market-related increases in a project's debt or equity financing costs; and/or • nonperformance or force majeure by, or disputes with, vendors, suppliers, contractors, or sub-contractors involved with a project. If we are unable to complete capital projects at their expected costs or in a timely manner our financial condition, results of operations, or cash flows could be materially and adversely affected. Delays in making required changes or upgrades to our facilities could subject us to fines or penalties as well as affect our ability to supply certain products we make. In addition, our revenues may not increase immediately upon the expenditure of funds on a particular project. For instance, if we build a new refinery processing unit, the construction will occur over an extended period of time and we will not receive any material increases in revenues until after completion of the project. Moreover, we may construct facilities to capture anticipated future growth in demand for refined products in a region in which such growth does not materialize. As a result, new capital investments may not achieve our expected investment return, which could adversely affect our financial condition or results of operations. Our forecasted internal rates of return are also based upon our projections of future market fundamentals which are not within our control, including changes in general economic conditions, available alternative supply and customer demand. An additional component of our growth strategy is to selectively acquire complementary assets for our refining operations in order to increase earnings and cash flow. Our ability to do so will be dependent upon a number of factors, including our ability to identify attractive acquisition candidates, consummate acquisitions on favorable terms, successfully integrate acquired assets and obtain financing to fund acquisitions and to support our growth, and other factors beyond our control. Risks associated with acquisitions include those relating to: • • diversion of management time and attention from our existing business; challenges in managing the increased scope, geographic diversity and complexity of operations and inefficiencies that may result therefrom; 21 Table of Content • • • • • • difficulties in integrating the financial, technological and management standards, processes, procedures and controls of an acquired business with those of our existing operations; liability for known or unknown environmental conditions or other contingent liabilities not covered by indemnification or insurance; greater than anticipated expenditures required for compliance with environmental or other regulatory standards or for investments to improve operating results; difficulties or delays in achieving anticipated operational improvements or benefits; incurrence of additional indebtedness to finance acquisitions or capital expenditures relating to acquired assets; and issuance of additional equity, which could result in further dilution of the ownership interest of existing stockholders. Any acquisitions that we do consummate may have adverse effects on our business and operating results. We may incur significant costs to comply with new or changing environmental, energy, health and safety laws and regulations, and face potential exposure for environmental matters. Refinery and pipeline operations are subject to federal, state and local laws regulating, among other things, the generation, storage, handling, use and transportation of petroleum and hazardous substances by pipeline, truck, rail and barge, the emission and discharge of materials into the environment, waste management, and characteristics and composition of gasoline and diesel fuels, and other matters otherwise relating to the protection of the environment. Permits or other authorizations are required under these laws for the operation of our refineries, pipelines and related operations, and these permits and authorizations are subject to revocation, modification and renewal or may require operational changes, which may involve significant costs. Furthermore, a violation of permit conditions or other legal or regulatory requirements could result in substantial fines, criminal sanctions, permit revocations, injunctions, and/or refinery shutdowns. In addition, major modifications of our operations due to changes in the law could require changes to our existing permits or expensive upgrades to our existing pollution control equipment, which could have a material adverse effect on our business, financial condition, or results of operations. Over the years, there have been ongoing communications, including notices of violations, about environmental matters between us and federal and state authorities, some of which have resulted or will result in changes to operating procedures and in capital expenditures. Compliance with applicable environmental laws, regulations and permits will continue to have an impact on our operations, results of our operations and capital requirements. As is the case with all companies engaged in industries similar to ours, we face potential exposure to future claims and lawsuits involving environmental matters. The matters include, but are not limited to, soil, groundwater and waterway contamination, air pollution, personal injury and property damage allegedly caused by substances which we manufactured, handled, used, released or disposed. We are and have been the subject of various state, federal and private proceedings relating to environmental regulations, conditions and inquiries. Current and future environmental regulations are expected to require additional expenditures, including expenditures for investigation and remediation, which may be significant, at our facilities. To the extent that future expenditures for these purposes are material and can be reasonably determined, these costs are disclosed and accrued. Our operations are also subject to various laws and regulations relating to occupational health and safety. We maintain safety, training and maintenance programs as part of our ongoing efforts to ensure compliance with applicable laws and regulations. Compliance with applicable health and safety laws and regulations has required and continues to require substantial expenditures. Failure to appropriately manage occupational health and safety risks associated with our business could also adversely impact our employees, communities, stakeholders, reputation and results of operations. We cannot predict what additional health and environmental legislation or regulations will be enacted or become effective in the future or how existing or future laws or regulations will be administered or interpreted with respect to our operations. However, new environmental laws and regulations, including new regulations relating to alternative energy sources and the risk of global climate change, new interpretations of existing laws and regulations, increased governmental enforcement or other developments could require us to make additional unforeseen expenditures. For example, the EPA has begun regulating certain sources of greenhouse gas emissions, or “GHGs,” (including carbon dioxide, methane and nitrous oxides) from large stationary sources like refineries under the authority of the CAA, and it is possible that Congress could pass federal legislation that creates a comprehensive GHG regulatory program, either directly or indirectly, such as via a federal renewal energy standard. Also, new federal or state legislation or regulatory programs that restrict emissions of GHGs in areas where we conduct business could adversely affect demand for our products and our results of operations. 22 Table of Content The costs of environmental and safety regulations are already significant and compliance with more stringent laws or regulations or adverse changes in the interpretation of existing regulations by government agencies could have an adverse effect on the financial position and the results of our operations and could require substantial expenditures for the installation and operation of systems and equipment that we do not currently possess. From time to time, new federal energy policy legislation is enacted by the U.S. Congress. For example, in December 2007, the U.S. Congress passed the Energy Independence and Security Act, which, among other provisions, mandates annually increasing levels for the use of renewable fuels such as ethanol, commencing in 2008 and escalating for 15 years, as well as increasing energy efficiency goals, including higher fuel economy standards for motor vehicles, among other steps. These statutory mandates may have the impact over time of offsetting projected increases in the demand for refined petroleum products in certain markets, particularly gasoline. In the near term, the new renewable fuel standard presents ethanol production and logistics challenges for both the ethanol and refining industries and may require additional capital expenditures or expenses by us to accommodate increased ethanol use. Other legislative changes may similarly alter the expected demand and supply projections for refined petroleum products in ways that cannot be predicted. For additional information on regulations and related liabilities or potential liabilities affecting our business, see “Regulation” under Items 1 and 2, “Business and Properties,” and Item 3, “Legal Proceedings.” The adoption of climate change legislation by Congress could result in increased operating costs and reduced demand for the refined products we produce. In December 2009, the EPA determined that emissions of carbon dioxide, methane and other GHGs present an endangerment to public health and the environment because emissions of such gases are, according to the EPA, contributing to warming of the earth's atmosphere and other climatic changes. Based on these findings, the EPA has begun adopting and implementing regulations to restrict emissions of GHGs under existing provisions of the federal CAA. For example, the EPA adopted rules that require certain large stationary sources to obtain permits to authorize emissions of GHGs. The EPA’s rules relating to emissions of GHGs from large stationary sources of emissions were, for the most part, upheld by the U.S. Supreme Court in 2014. The EPA has also adopted rules requiring the reporting of GHG emissions from specified large GHG emission sources in the United States, including petroleum refineries, on an annual basis. The EPA has also announced its intention to issue a New Source Performance Standard directly regulating GHG emissions from refineries, although recent statements from EPA Administrator McCarthy indicate that issuance of such Performance Standard is not imminent.. In addition, the U.S. Congress has from time to time considered adopting legislation to reduce emissions of GHGs and almost one-half of the states have already taken legal measures to reduce emissions of GHGs primarily through the planned development of GHG emission inventories and/or regional GHG cap and trade programs. These cap and trade programs generally work by requiring major sources of emissions, such as electric power plants, or major producers of fuels, such as refineries and gas processing plants, to acquire and on an annual basis surrender emission allowances. The number of allowances available for purchase is reduced over time in an effort to achieve the overall GHG emission reduction goal. The adoption of legislation or regulatory programs to reduce emissions of GHGs could require us to incur increased operating costs, such as costs to purchase and operate emissions control systems, to acquire emissions allowances or comply with new regulatory or reporting requirements. Any such legislation or regulatory programs could also increase the cost of consuming, and thereby reduce demand for, the refined products that we produce. Consequently, legislation and regulatory programs to reduce emissions of GHGs could have an adverse effect on our business, financial condition and results of operations. In addition, some scientists have concluded that increasing concentrations of GHGs in the Earth's atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, floods and other climatic events. If any such events were to occur, they could have an adverse effect on our financial condition and results of operations. 23 Table of Content Our operations are subject to operational hazards and unforeseen interruptions for which we may not be adequately insured. Our operations are subject to operational hazards and unforeseen interruptions such as natural disasters, adverse weather, accidents, fires, explosions, hazardous materials releases, power failures, mechanical failures and other events beyond our control. These events might result in a loss of equipment or life, injury, or extensive property damage or destruction of property, as well as a curtailment or an interruption in our operations and may affect our ability to meet marketing commitments. We maintain significant insurance coverage, but it does not cover all potential losses, costs or liabilities, and our business interruption insurance coverage generally does not apply unless a business interruption exceeds 45 days. If any refinery were to experience an interruption in operations, earnings from the refinery could be materially adversely affected (to the extent not recoverable through insurance) because of lost production and repair costs. The availability of adequate insurance may be affected by conditions in the insurance market over which we have no control, resulting in the inability to maintain or obtain insurance of the type and amount we desire at reasonable rates. As a result of market conditions, premiums and deductibles for certain of our insurance policies could increase or, in some instances, certain insurance could become unavailable or available only for reduced amounts of coverage. We could suffer losses for uninsurable or uninsured risks or in amounts in excess of our existing insurance coverage. The occurrence of an event that is not fully covered by insurance could have a material adverse effect on our business, financial condition and results of operations. The energy industry is highly capital intensive, and the entire or partial loss of individual facilities can result in significant costs to both industry companies, such as us, and their insurance carriers. In recent years, several large energy industry claims have resulted in significant increases in the level of premium costs and deductible periods for participants in the energy industry. As a result of large energy industry claims, insurance companies that have historically participated in underwriting energy-related facilities may discontinue that practice or demand significantly higher premiums or deductible periods to cover these facilities. If significant changes in the number or financial solvency of insurance underwriters for the energy industry occur, or if other adverse conditions over which we have no control prevail in the insurance market, we may be unable to obtain and maintain adequate insurance at reasonable cost. In addition, we cannot assure you that our insurers will renew our insurance coverage on acceptable terms, if at all, or that we will be able to arrange for adequate alternative coverage in the event of non-renewal. Further, our underwriters could have credit issues that affect their ability to pay claims. The unavailability of full insurance coverage to cover events in which we suffer significant losses could have a material adverse effect on our business, financial condition and results of operations. The availability and cost of renewable identification numbers could have an adverse effect on our financial condition and results of operations. In addition, the EPA has not yet finalized the 2014 percentage standards under its Renewable Fuel Standard 2 (“RFS2”) regulations. Pursuant to the 2007 Energy Independence and Security Act, the EPA promulgated the RFS2 regulations reflecting the increased volume of renewable fuels mandated to be blended into the nation's fuel supply. The regulations, in part, require refiners to add annually increasing amounts of “renewable fuels” to their petroleum products or purchase credits, known as renewable identification numbers (“RINs”), in lieu of such blending. We currently purchase RINs for some fuel categories on the open market in order to comply with the quantity of renewable fuels we are required to blend under the RFS2. Recently, due in part to the nation's fuel supply approaching the “blend wall” (the 10% ethanol limit prescribed by most automobile warranties), the price of RINs has been extremely volatile with the price dramatically increasing in recognition of the decrease in RINs availability. While we cannot predict the future prices of RINs, the costs to obtain the necessary number of RINs could be material. If we are unable to pass the costs of compliance with the RFS2 on to our customers, if sufficient RINs are unavailable for purchase, if we have to pay a significantly higher price for RINs or if we are otherwise unable to meet the RFS2 mandates, our financial condition and results of operations could be adversely affected. Additionally, the EPA has not yet finalized the 2014 percentage standards under its RFS2 program. When the EPA ultimately finalizes the required blending percentages for 2014, such levels could be higher or lower than amounts estimated and accrued for in our consolidated financial statements as of December 31, 2014. Competition in the refining and marketing industry is intense, and an increase in competition in the markets in which we sell our products could adversely affect our earnings and profitability. We compete with a broad range of refining and marketing companies, including certain multinational oil companies. Because of their geographic diversity, larger and more complex refineries, integrated operations and greater resources, some of our competitors may be better able to withstand volatile market conditions, to obtain crude oil in times of shortage and to bear the economic risks inherent in all areas of the refining industry. 24 Table of Content We are not engaged in petroleum exploration and production activities and do not produce any of the crude oil feedstocks used at our refineries. We do not have a retail business and therefore are dependent upon others for outlets for our refined products. Certain of our competitors, however, obtain a portion of their feedstocks from company-owned production and have retail outlets. Competitors that have their own production or extensive retail outlets, with brand-name recognition, are at times able to offset losses from refining operations with profits from producing or retailing operations, and may be better positioned to withstand periods of depressed refining margins or feedstock shortages. In recent years there have been several refining and marketing consolidations or acquisitions between entities competing in our geographic market. These transactions could increase the future competitive pressures on us. The markets in which we compete may be impacted by competitors' plans for expansion projects and refinery improvements that could increase the production of refined products in our areas of operation and significantly affect our profitability. Also, the potential operation of new or expanded refined product transportation pipelines, or the conversion of existing pipelines into refined product transportation pipelines, could impact the supply of refined products to our existing markets and negatively affect our profitability. In addition, we compete with other industries that provide alternative means to satisfy the energy and fuel requirements of our industrial, commercial and individual consumers. The more successful these alternatives become as a result of governmental regulations, technological advances, consumer demand, improved pricing or otherwise, the greater the impact on pricing and demand for our products and our profitability. There are presently significant governmental and consumer pressures to increase the use of alternative fuels in the United States. A disruption to or proration of the refined product distribution systems we utilize could negatively impact our profitability. We utilize various common carrier or other third party pipeline systems to deliver our products to market. The key systems utilized by the Cheyenne, El Dorado, Navajo, Woods Cross, and Tulsa Refineries are Rocky Mountain, NuStar Energy, SFPP and Plains, Chevron, and Magellan, respectively. All five refineries also utilize systems owned by HEP. If these key pipelines or their associated tanks and terminals become inoperative or decrease the capacity available to us, we may not be able to sell our product, or we may be required to hold our product in inventory or supply products to our customers through an alternative pipeline or by rail or additional tanker trucks from the refinery, all of which could increase our costs and result in a decline in profitability. We may be subject to information technology system failures, network disruptions and breaches in data security. Information technology system failures, network disruptions (whether intentional by a third party or due to natural disaster), breaches of network or data security, or disruption or failure of the network system used to monitor and control pipeline operations could disrupt our operations by impeding our processing of transactions, our ability to protect customer or company information and our financial reporting. Our computer systems, including our back-up systems, could be damaged or interrupted by power outages, computer and telecommunications failures, computer viruses, internal or external security breaches, events such as fires, earthquakes, floods, tornadoes and hurricanes, and/or errors by our employees. There can be no assurance that a system failure or data security breach will not have a material adverse effect on our financial condition and results of operations. 25 Table of Content We may not be able to obtain funding on acceptable terms or at all because of volatility and uncertainty in the credit and capital markets. This may hinder or prevent us from meeting our future capital needs. The domestic and global financial markets and economic conditions are disrupted and volatile from time to time due to a variety of factors, including low consumer confidence, high unemployment, geoeconomic and geopolitical issues, weak economic conditions and uncertainty in the financial services sector. In addition, the fixed-income markets have experienced periods of extreme volatility, which negatively impacted market liquidity conditions. As a result, the cost of raising money in the debt and equity capital markets has increased substantially at times while the availability of funds from these markets diminished significantly. In particular, as a result of concerns about the stability of financial markets generally and the solvency of lending counterparties specifically, the cost of obtaining money from the credit markets may increase as many lenders and institutional investors increase interest rates, enact tighter lending standards, refuse to refinance existing debt on similar terms or at all and reduce, or in some cases cease, to provide funding to borrowers. In addition, lending counterparties under any existing revolving credit facility and other debt instruments may be unwilling or unable to meet their funding obligations, or we may experience a decrease in our capacity to issue debt or obtain commercial credit or a deterioration in our credit profile, including a rating agency lowering or withdrawing of our credit ratings if, in its judgment, the circumstances warrant. Due to these factors, we cannot be certain that new debt or equity financing will be available on acceptable terms. If funding is not available when needed, or is available only on unfavorable terms, we may be unable to meet our obligations as they come due or we may be required to sell assets. Moreover, without adequate funding, we may be unable to execute our growth strategy, complete future acquisitions or construction projects, take advantage of other business opportunities or respond to competitive pressures, comply with regulatory requirements, or meet our short-term or long-term working capital requirements, any of which could have a material adverse effect on our revenues and results of operations. Failure to comply with regulatory requirements in a timely manner or meet our short- term or long-term working capital requirements could subject us to regulatory action. We depend upon HEP for a substantial portion of the crude supply and distribution network that serve our refineries and we own a significant equity interest in HEP. We currently own a 39% interest in HEP, including the 2% general partner interest. HEP operates a system of crude oil and petroleum product pipelines, distribution terminals and refinery tankage in Arizona, Idaho, Kansas, New Mexico, Oklahoma, Texas, Utah, Washington and Wyoming. HEP generates revenues by charging tariffs for transporting petroleum products and crude oil through its pipelines, leasing certain pipeline capacity to Alon, charging fees for terminalling refined products and other hydrocarbons and storing and providing other services at its terminals. HEP serves the Cheyenne, El Dorado, Navajo, Woods Cross and Tulsa Refineries under several long-term pipeline and terminal, tankage and throughput agreements expiring in 2019 through 2026. Furthermore, our financial statements include the consolidated results of HEP. HEP is subject to its own operating and regulatory risks, including, but not limited to: • • • • • • • its reliance on its significant customers, including us; competition from other pipelines; environmental regulations affecting pipeline operations; operational hazards and risks; pipeline tariff regulations affecting the rates HEP can charge; limitations on additional borrowings and other restrictions due to HEP's debt covenants; and other financial, operational and legal risks. The occurrence of any of these risks could directly or indirectly affect HEP's as well as our financial condition, results of operations and cash flows as HEP is a consolidated VIE. Additionally, these risks could affect HEP's ability to continue operations which could affect their ability to serve our supply and distribution network needs. For additional information about HEP, see “Holly Energy Partners, L.P.” under Items 1 and 2, “Business and Properties.” For risks related to HEP's business, see Item 1A of HEP's Annual Report on Form 10-K for the fiscal year ended December 31, 2014. We are exposed to the credit risks, and certain other risks, of our key customers and vendors. We are subject to risks of loss resulting from nonpayment or nonperformance by our customers. We derive a significant portion of our revenues from contracts with key customers. If any of our key customers default on their obligations to us, our financial results could be adversely affected. Furthermore, some of our customers may be highly leveraged and subject to their own operating and regulatory risks. In addition, nonperformance by vendors who have committed to provide us with products or services could result in higher costs or interfere with our ability to successfully conduct our business. 26 Table of Content Any substantial increase in the nonpayment and/or nonperformance by our customers or vendors could have a material adverse effect on our results of operations and cash flows. Terrorist attacks, and the threat of terrorist attacks or domestic vandalism, have resulted in increased costs to our business. Continued global hostilities or other sustained military campaigns may adversely impact our results of operations. The long-term impacts of terrorist attacks, such as the attacks that occurred on September 11, 2001, and the threat of future terrorist attacks on the energy transportation industry in general, and on us in particular, are not known at this time. Increased security measures taken by us as a precaution against possible terrorist attacks or vandalism have resulted in increased costs to our business. Future terrorist attacks could lead to even stronger, more costly initiatives or regulatory requirements. Uncertainty surrounding continued global hostilities or other sustained military campaigns may affect our operations in unpredictable ways, including disruptions of crude oil supplies and markets for refined products, and the possibility that infrastructure facilities could be direct targets of, or indirect casualties of, an act of terror. In addition, disruption or significant increases in energy prices could result in government-imposed price controls. Any one of, or a combination of, these occurrences could have a material adverse effect on our business, financial condition and results of operations. Changes in the insurance markets attributable to terrorist attacks could make certain types of insurance more difficult for us to obtain. Moreover, the insurance that may be available to us may be significantly more expensive than our existing insurance coverage. Instability in the financial markets as a result of terrorism or war could also affect our ability to raise capital including our ability to repay or refinance debt. Increases in required fuel economy and regulation of CO2 emissions from motor vehicles may reduce demand for transportation fuels. In 2010, the EPA and the National Highway Traffic Safety Administration (“NHTSA”) finalized new standards, raising the required Corporate Average Fuel Economy (“CAFE”) of the nation's passenger fleet by 40% to approximately 35 miles per gallon (“m.p.g.”) by 2016 and imposing the first-ever federal GHG emissions standards on cars and light trucks. In September 2011, the EPA and the Department of Transportation finalized first-time standards for fuel economy of medium and heavy duty trucks. On August 28, 2012 the EPA and NHTSA adopted standards through model year 2025 in two phases. The first phase establishes final standards for 2017-2021 model year vehicles that are projected to require 40.3 - 41.0 m.p.g. in model year 2021 on an average industry fleet- wide basis. The second phase of the CAFE program represents non-final “augural” standards for 2022-2025 model year vehicles that are projected to require 48.7 - 49.7 m.p.g. in model year 2025, on an average industry fleet-wide basis. Such increases in fuel economy standards, along with mandated increases in use of renewable fuels discussed above, could result in decreasing demand for petroleum fuels. Decreasing demand for petroleum fuels could have a material effect on our financial condition and results of operation. To successfully operate our petroleum refining facilities, we are required to expend significant amounts for capital outlays and operating expenditures. The refining business is characterized by high fixed costs resulting from the significant capital outlays associated with refineries, terminals, pipelines and related facilities. We are dependent on the production and sale of quantities of refined products at refined product margins sufficient to cover operating costs, including any increases in costs resulting from future inflationary pressures or market conditions and increases in costs of fuel and power necessary in operating our facilities. Furthermore, future major capital investment, various environmental compliance related projects, regulatory requirements or competitive pressures could result in additional capital expenditures, which may not produce a return on investment. Such capital expenditures may require significant financial resources that may be contingent on our access to capital markets and commercial bank loans. Additionally, other matters, such as regulatory requirements or legal actions, may restrict our access to funds for capital expenditures. 27 Table of Content Our refineries consist of many processing units, a number of which have been in operation for many years. One or more of the units may require unscheduled downtime for unanticipated maintenance or repairs that are more frequent than our scheduled turnaround for such units. Scheduled and unscheduled maintenance could reduce our revenues during the period of time that the units are not operating. We have taken significant measures to expand and upgrade units in our refineries by installing new equipment and redesigning older equipment to improve refinery capacity. The installation and redesign of key equipment at our refineries involves significant uncertainties, including the following: our upgraded equipment may not perform at expected throughput levels; operating costs of the upgraded equipment may be higher than expected; the yield and product quality of new equipment may differ from design and/or specifications and redesign, modification or replacement of the equipment may be required to correct equipment that does not perform as expected, which could require facility shutdowns until the equipment has been redesigned or modified. Any of these risks associated with new equipment, redesigned older equipment, or repaired equipment could lead to lower revenues or higher costs or otherwise have a negative impact on our future financial condition and results of operations. In addition, we expect to execute turnarounds at our refineries, which involve numerous risks and uncertainties. These risks include delays and incurrence of additional and unforeseen costs. The turnarounds allow us to perform maintenance, upgrades, overhaul and repair of process equipment and materials, during which time all or a portion of the refinery will be under scheduled downtime. We may be unable to pay future regular and/or special dividends. We will only be able to pay dividends from our available cash on hand, cash from operations or borrowings under our credit agreement. The declaration of future regular and/or special dividends on our common stock will be at the discretion of our board of directors and will depend upon many factors, including our results of operations, financial condition, earnings, capital requirements, and restrictions in our debt agreements and legal requirements. We cannot assure you that any dividends will be paid or the frequency of such payments. Product liability claims and litigation could adversely affect our business and results of operations. A significant portion of our operating responsibility on refined product pipelines is to insure the quality and purity of the products loaded at our loading racks. If our quality control measures were to fail, we may have contaminated or off-specification commingled pipelines and storage tanks or off-specification product could be sent to public gasoline stations. These types of incidents could result in product liability claims from our customers. Product liability is a significant commercial risk. Substantial damage awards have been made in certain jurisdictions against manufacturers and resellers based upon claims for injuries caused by the use of or exposure to various products. There can be no assurance that product liability claims against us would not have a material adverse effect on our business or results of operations or our ability to maintain existing customers or retain new customers. Our hedging transactions may limit our gains and expose us to other risks. We periodically enter into derivative transactions as it relates to inventory levels and/or future production to manage the risks from changes in the prices of crude oil, refined products and other feedstocks. These transactions limit our potential gains if commodity prices move above or below the certain price levels established by our hedging instruments. We hedge price risk on inventories above our target levels to minimize the impact these price fluctuations have on our earnings and cash flows. Consequently, our hedging results may fluctuate significantly from one reporting period to the next depending on commodity price fluctuations and our relative physical inventory positions. These transactions may also expose us to risks of financial losses; for example, if our production is less than we anticipated at the time we entered into a hedge agreement or if a counterparty to our hedge agreements fails to perform its obligations under the agreements. Changes in our credit profile, or a significant increase in the price of crude oil, may affect our relationship with our suppliers, which could have a material adverse effect on our liquidity and limit our ability to purchase sufficient quantities of crude oil to operate our refineries at desired capacity. An unfavorable credit profile, or a significant increase in the price of crude oil, could affect the way crude oil suppliers view our ability to make payments and induce them to shorten the payment terms of their invoices with us or require credit enhancement. Due to the large dollar amounts and volume of our crude oil and other feedstock purchases, any imposition by our suppliers of more burdensome payment terms or credit enhancement requirements on us may have a material adverse effect on our liquidity and our ability to make payments to our suppliers. This in turn could cause us to be unable to operate our refineries at desired capacity. A failure to operate our refineries at desired capacity could adversely affect our profitability and cash flow. 28 Table of Content Our credit facility contains certain covenants and restrictions that may constrain our business and financing activities. The operating and financial restrictions and covenants in our credit facility and any future financing agreements could adversely affect our ability to finance future operations or capital needs or to engage, expand or pursue our business activities. For example, our revolving credit facility imposes usual and customary requirements for this type of credit facility, including: (i) limitations on liens and indebtedness; (ii) a prohibition on changes in control and (iii) restrictions on engaging in mergers and consolidations. If we fail to satisfy the covenants set forth in the credit facility or another event of default occurs under the credit facility, the maturity of the loan could be accelerated or we could be prohibited from borrowing for our future working capital needs and issuing letters of credit. We might not have, or be able to obtain, sufficient funds to make these immediate payments. If we desire to undertake a transaction that is prohibited by the covenants in our credit facility, we will need to obtain consent under our credit facility. Such refinancing may not be possible or may not be available on commercially acceptable terms. Our business may suffer due to a change in the composition of our Board of Directors, or by the departure of any of our key senior executives or other key employees. Furthermore, a shortage of skilled labor or disruptions in our labor force may make it difficult for us to maintain labor productivity. Our future performance depends to a significant degree upon the continued contributions of our senior management team and key technical personnel. We do not currently maintain key man life insurance, non-compete agreements, or employment agreements with respect to any member of our senior management team. The loss or unavailability to us of any member of our senior management team or a key technical employee could significantly harm us. We face competition for these professionals from our competitors, our customers and other companies operating in our industry. To the extent that the services of members of our senior management team and key technical personnel would be unavailable to us for any reason, we may be required to hire other personnel to manage and operate our company. We may not be able to locate or employ such qualified personnel on acceptable terms, or at all. Furthermore, our operations require skilled and experienced laborers with proficiency in multiple tasks. A shortage of trained workers due to retirements or otherwise could have an adverse impact on our labor productivity and costs and our ability to expand production in the event there is an increase in the demand for our products and services, which could adversely affect our operations. As of December 31, 2014, approximately 33% of our employees were represented by labor unions under collective bargaining agreements with various expiration dates. We may not be able to renegotiate our collective bargaining agreements when they expire on satisfactory terms or at all. A failure to do so may increase our costs. In addition, our existing labor agreements may not prevent a strike or work stoppage at any of our facilities in the future, and any work stoppage could negatively affect our results of operations and financial condition. The market price of our common stock may fluctuate significantly, and the value of a stockholder’s investment could be impacted. The market price of our common stock may be influenced by many factors, some of which are beyond our control, including: • • • • • • • • our quarterly or annual earnings or those of other companies in our industry; changes in accounting standards, policies, guidance, interpretations or principles; general economic and stock market conditions; the failure of securities analysts to cover our common stock or changes in financial estimates by analysts; future sales of our common stock; announcements by us or our competitors of significant contracts or acquisitions; sales of common stock by us, our senior officers or our affiliates; and/or the other factors described in these Risk Factors. In recent years, the stock market has experienced extreme price and volume fluctuations. This volatility has had a significant impact on the market price of securities issued by many companies, including companies in our industry. The price of our common stock could fluctuate based upon factors that have little or nothing to do with our company, and these fluctuations could materially reduce our stock price. Item 1B. Unresolved Staff Comments We do not have any unresolved staff comments. 29 Table of Content Item 3. Legal Proceedings Commitment and Contingency Reserves We periodically establish reserves for certain legal proceedings. The establishment of a reserve involves an estimation process that includes the advice of legal counsel and subjective judgment of management. While management believes these reserves to be adequate, future changes in the facts and circumstances could result in the actual liability exceeding the estimated ranges of loss and amounts accrued. While the outcome and impact on us cannot be predicted with certainty, based on advice of counsel, management believes that the resolution of these proceedings through settlement or adverse judgment will not either individually or in the aggregate have a materially adverse effect on our financial condition, results of operations or cash flows. Environmental Matters We are reporting the following proceedings to comply with SEC regulations which require us to disclose proceedings arising under federal, state or local provisions regulating the discharge of materials into the environment or protecting the environment if we reasonably believe that such proceedings may result in monetary sanctions of $100,000 or more. Our respective subsidiaries have or will develop corrective action plans regarding these disclosures that will be implemented in consultation with the respective federal and state agencies. It is not possible to predict the ultimate outcome of these proceedings, although none are currently expected to have a material effect on our financial condition, results of operations or cash flows. Frontier Refining LLC (“FR”), our wholly-owned subsidiary, completed certain environmental audits at the Cheyenne Refinery regarding compliance with federal and state environmental requirements. By letters dated October 5, 2012, November 7, 2012, and January 10, 2013, and pursuant to EPA's audit policy to the extent applicable, FR submitted reports to the EPA voluntarily disclosing non-compliance with certain emission limitations, reporting requirements, and provisions of a 2009 federal consent decree. By letters dated October 31, 2012, February 6, 2013, June 21, 2013, July 9, 2013 and July 25, 2013, and pursuant to applicable Wyoming audit statutes, FR submitted environmental audit reports to the Wyoming Department of Environmental Quality (“WDEQ”) voluntarily disclosing non-compliance with certain notification, reporting, and other provisions of the refinery's state air permit and other environmental regulatory requirements. Additional self-disclosures and follow-up correspondence are anticipated as the audit activities are completed. No further action has been taken by either agency at this time. The Cheyenne Refinery also has one outstanding Notice of Violations issued in January 2013 that is subject to ongoing settlement negotiations with the WDEQ. The Cheyenne Refinery received a letter from the EPA dated December 22, 2014, reviewing air emission incident reports submitted to the EPA during the period 2011 to 2013 and assessing a penalty for a number of these incidents. The Cheyenne Refinery reviewed the EPA's penalty assessment with legal counsel and has paid the penalty. Between November 2010 and February 2012, certain of our subsidiaries submitted multiple reports to the EPA to voluntarily disclose non-compliance with fuels regulations at the Cheyenne, El Dorado, Navajo, Tulsa and Woods Cross refineries and at the Cedar City, Utah and Henderson, Colorado terminals. Our subsidiaries have complied with all EPA requests for additional information regarding the voluntary disclosures. The EPA and our subsidiaries are now engaged in settlement discussions with the EPA that may resolve the voluntarily disclosed non-compliance events. On July 2, 2014, the Woods Cross Refinery received a letter issued by the U.S. EPA Region 8 dated June 26, 2014 describing certain instances where the Woods Cross Refinery may not be in compliance with the refinery's 2008 Consent Decree and calculating proposed stipulated penalties in accordance with that decree. The letter requested information and documentation setting forth Woods Cross's position on the EPA's assessment and further requested that Woods Cross provide reasons why the EPA's assessment may be incorrect. Woods Cross evaluated the EPA letter and submitted a response on July 29, 2014, explaining that many of the instances of apparent noncompliance are unwarranted and for those no penalty should be assessed. By letter dated February 10, 2015, the EPA considered the information provided by the Woods Cross Refinery and assessed a stipulated penalty that is less than $100,000. 30 Table of Content In correspondence dated December 26, 2013, the Oklahoma Department of Environmental Quality (“ODEQ”) notified our Tulsa Refinery of allegations of noncompliance with certain regulations, permit conditions and consent decree provisions at the Tulsa East and West refineries. ODEQ intends to seek penalties for allegations of failure to meet various permit or consent decree requirements, including failure to timely install monitoring equipment on a Tulsa West refinery flare. On January 21, 2015, the ODEQ notified the Tulsa Refinery that no penalty would be assessed for the Tulsa West refinery flare issue. As a result, any penalties on the remaining issues are expected to be less than $100,000. Other We are a party to various other litigation and proceedings that we believe, based on advice of counsel, will not either individually or in the aggregate have a materially adverse impact on our financial condition, results of operations or cash flows. Item 4. Mine Safety Disclosures Not Applicable. 31 Table of Content PART II Item 5. Market for the Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Our common stock is traded on the New York Stock Exchange under the trading symbol “HFC.” The following table sets forth the range of the daily high and low sales prices per share of common stock, dividends declared per share and the trading volume of common stock for the periods indicated: Years Ended December 31, High Low Dividends Trading Volume 2014 Fourth quarter Third quarter Second quarter First quarter 2013 Fourth quarter Third quarter Second quarter First quarter $ $ $ $ $ $ $ $ 46.47 51.31 53.42 50.74 50.63 47.21 52.87 59.20 $ $ $ $ $ $ $ $ 35.31 42.76 43.61 43.17 39.65 38.98 39.96 42.76 $ $ $ $ $ $ $ $ 0.82 0.82 0.82 0.80 0.80 0.80 0.80 0.80 152,657,400 139,658,000 152,909,200 174,540,200 230,186,600 174,416,900 229,246,900 217,439,700 In September 2014, our Board of Directors approved a $500 million share repurchase program authorizing us to repurchase common stock in the open market or through privately negotiated transactions. The following table includes repurchases made under this program during the fourth quarter of 2014. Period October 2014 November 2014 December 2014 Total for October to December 2014 Total Number of Shares Purchased 460,000 80,000 Average Price Paid Per Share 43.29 $ 44.35 $ — — $ 540,000 Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs Maximum Dollar Value of Shares that May Yet Be Purchased under the Plans or Programs 460,000 80,000 $ $ — $ 540,000 447,928,446 444,380,840 444,380,840 In February 2015, our Board of Directors approved a $500 million share repurchase program, which replaced all existing share repurchase programs including approximately $425 million remaining under the existing $500 million share repurchase program. The timing and amount of stock repurchases will depend on market conditions, corporate, regulatory and other relevant considerations. This program may be discontinued at any time by our Board of Directors. As of February 9, 2015, we had approximately 124,680 stockholders, including beneficial owners holding shares in street name. We intend to consider the declaration of a dividend on a quarterly basis, although there is no assurance as to future dividends since they are dependent upon future earnings, capital requirements, our financial condition and other factors. Our senior notes limit the payment of dividends at any time we are not rated investment grade by both Moody's and Standard & Poor's. See Note 11 “Debt” in the Notes to Consolidated Financial Statements. 32 Table of Content Item 6.

Management’s Discussion and Analysis of Financial Condition and Results of Operations This Item 7 contains “forward-looking” statements. See “Forward-Looking Statements” at the beginning of this Annual Report on Form 10-K. In this document, the words “we,” “our,” “ours” and “us” refer only to HollyFrontier and its consolidated subsidiaries or to HollyFrontier or an individual subsidiary and not to any other person with certain exceptions. Generally, the words “we,” “our,” “ours” and “us” include HEP and its subsidiaries as consolidated subsidiaries of HollyFrontier, unless when used in disclosures of transactions or obligations between HEP and HollyFrontier or its other subsidiaries. This document contains certain disclosures of agreements that are specific to HEP and its consolidated subsidiaries and do not necessarily represent obligations of HollyFrontier. When used in descriptions of agreements and transactions, “HEP” refers to HEP and its consolidated subsidiaries. Overview We are principally an independent petroleum refiner that produces high-value refined products such as gasoline, diesel fuel, jet fuel, specialty lubricant products, and specialty and modified asphalt. We own and operate refineries having a combined crude oil processing capacity of 443,000 barrels per day that serve markets throughout the Mid-Continent, Southwest and Rocky Mountain regions of the United States. Our refineries are located in El Dorado, Kansas (the El Dorado Refinery), Tulsa, Oklahoma (the Tulsa Refineries), which comprise two production facilities, the Tulsa West and East facilities, a petroleum refinery in Artesia, New Mexico, which operates in conjunction with crude, vacuum distillation and other facilities situated 65 miles away in Lovington, New Mexico (the Navajo Refinery), Cheyenne, Wyoming (the Cheyenne Refinery) and Woods Cross, Utah (the Woods Cross Refinery). For the year ended December 31, 2014, net income attributable to HollyFrontier stockholders was $281.3 million compared to $735.8 million and $1,727.2 million for the years ended December 31, 2013, and 2012, respectively. Overall gross refining margins per produced product sold for 2014 decreased 13% and 44% over the respective years ended December 31, 2013 and 2012, which was due principally to significant contraction in WTI to Brent crude differentials. Additionally, net income for the year ended December 31, 2014 reflects a $397.5 million ($244.0 million after-tax) non-cash charge to adjust the value of our inventory to the lower of cost or market at December 31, 2014. OUTLOOK Our profitability is affected by the spread, or differential, between the market prices for crude oil on the world market (which is based on the price for Brent, North Sea Crude) and the price for inland U.S. crude oil (which is based on the price for WTI). We expect continued volatility in the pricing relationship between inland and coastal crude. After reaching parity in early 2015, we've already recently witnessed the inland/coastal crude differential widen to more than $9.00 per barrel. We believe new inbound pipeline capacity, current storage economics and upcoming refinery maintenance activity should continue to drive Cushing inventories higher and spreads wider throughout 2015. Pursuant to the 2007 Energy Independence and Security Act, the EPA promulgated the RFS2 regulations, which increased the volume of renewable fuels mandated to be blended into the nation's fuel supply. The regulations, in part, require refiners to add annually increasing amounts of “renewable fuels” to their petroleum products or purchase credits, known as RINs, in lieu of such blending. The price of RINs may be extremely volatile as observed in 2013, when prices escalated sharply due to real or perceived future shortages in RINs. Although our RINs costs remain material, the price of RINs has decreased significantly from 2013 highs, due in part to regulatory easing of the 2014 annual Renewable Volume Obligation, or RVO. As of December 31, 2014, we are purchasing RINs in order to meet approximately half of our renewable fuel requirements. Additionally, the EPA has not yet finalized the 2014 percentage standards under its RFS2 program. We cannot predict with certainty our exposure to increased RINs costs in the future, nor can we predict the extent by which costs associated with RFS2 will impact our future results of operations. A more detailed discussion of our financial and operating results for the years ended December 31, 2014, 2013 and 2012 is presented in the following sections. 34 Table of Content Results Of Operations Financial Data 2014 Years Ended December 31, 2013 (In thousands, except per share data) 2012 Sales and other revenues Operating costs and expenses: Cost of products sold (exclusive of depreciation and amortization): Cost of products sold (exclusive of lower of cost or market inventory valuation adjustment) Lower of cost or market inventory valuation adjustment Operating expenses (exclusive of depreciation and amortization) General and administrative expenses (exclusive of depreciation and amortization) Depreciation and amortization Total operating costs and expenses Income from operations Other income (expense): Earnings (loss) of equity method investments Interest income Interest expense Loss on early extinguishment of debt Gain on sale of assets Income before income taxes Income tax provision Net income Less net income attributable to noncontrolling interest Net income attributable to HollyFrontier stockholders Earnings per share attributable to HollyFrontier stockholders: Basic Diluted Cash dividends declared per common share Average number of common shares outstanding: Basic Diluted Other Financial Data Net cash provided by operating activities Net cash used for investing activities Net cash used for financing activities Capital expenditures EBITDA (1) $ 19,764,327 $ 20,160,560 $ 20,090,724 17,228,385 397,478 17,625,863 1,144,940 114,609 363,381 19,248,793 515,534 (2,007) 4,430 (43,646) (7,677) 866 (48,034) 467,500 141,172 326,328 45,036 281,292 1.42 1.42 3.26 197,243 197,428 $ $ $ $ 17,392,227 — 17,392,227 1,090,850 127,963 303,446 18,914,486 1,246,074 (2,072) 5,556 (68,050) (22,109) — (86,675) 1,159,399 391,576 767,823 31,981 735,842 3.66 3.64 3.20 200,419 201,234 $ $ $ $ 15,840,643 — 15,840,643 994,966 128,101 242,868 17,206,578 2,884,146 2,923 4,786 (104,186) — 326 (96,151) 2,787,995 1,027,962 1,760,033 32,861 1,727,172 8.41 8.38 3.10 204,379 205,274 2014 Years Ended December 31, 2013 (In thousands) 2012 $ 758,596 (292,322) $ (838,392) $ $ 564,821 $ 832,738 $ 869,174 (526,735) $ (1,160,035) $ $ 425,127 $ 1,515,467 1,662,687 (711,104) (772,788) 335,263 3,097,402 $ $ $ $ $ $ $ $ $ (1) Earnings before interest, taxes, depreciation and amortization, which we refer to as “EBITDA,” is calculated as net income plus (i) interest expense, net of interest income, (ii) income tax provision, and (iii) depreciation and amortization. EBITDA is not a calculation provided for under GAAP; however, the amounts included in the EBITDA calculation are derived from amounts included in our consolidated financial statements. EBITDA should not be considered as an alternative to net income or operating income as an indication of our operating performance or as an alternative to operating cash flow as a measure of liquidity. EBITDA is not necessarily comparable to similarly titled measures of other companies. EBITDA is presented here because it is a widely used financial indicator used by investors and analysts to measure performance. EBITDA is also used by our management for internal analysis and as a basis for financial covenants.

Results of Operations – Year Ended December 31, 2014 Compared to Year Ended December 31, 2013 Summary Net income attributable to HollyFrontier stockholders for the year ended December 31, 2014 was $281.3 million ($1.42 per basic and diluted share), a $454.6 million decrease compared to $735.8 million ($3.66 per basic and $3.64 per diluted share) for the year ended December 31, 2013. Net income decreased due principally to a non-cash lower of cost or market inventory valuation charge of $244.0 million, net of tax, and a year-over-year decrease in refining margins. Refinery gross margins for the year ended December 31, 2014 decreased to $13.98 per produced barrel from $15.99 for the year ended December 31, 2013. 36 Table of Content Sales and Other Revenues Sales and other revenues decreased 2% from $20,160.6 million for the year ended December 31, 2013 to $19,764.3 million for the year ended December 31, 2014 due to a decrease in year-over-year sales prices, partially offset by higher refined product sales volumes. The average sales price we received per produced barrel sold decreased 5% from $115.60 for the year ended December 31, 2013 to $110.19 for the year ended December 31, 2014. Sales and other revenues for the years ended December 31, 2014 and 2013 include $57.3 million and $53.4 million, respectively, in HEP revenues attributable to pipeline and transportation services provided to unaffiliated parties. Cost of Products Sold Cost of products sold decreased 1% from $17,392.2 million for the year ended December 31, 2013 to $17,228.4 million for the year ended December 31, 2014, due principally to a decrease in year-over-year crude costs, partially offset by higher refined product sales volumes. The average price we paid per barrel for crude oil and feedstocks and the transportation costs of moving the finished products to the market place decreased 3% from $99.61 for the year ended December 31, 2013 to $96.21 for the year ended December 31, 2014. Lower of Cost or Market Inventory Valuation Adjustment For the year ended December 31, 2014, we recorded a $397.5 million non-cash charge against income from operations to adjust the value of our inventory to the lower of cost or market at December 31, 2014. This is attributable to a significant decrease in market prices for crude oil and refined products at December 31, 2014. There was no comparable inventory valuation adjustment for the year ended December 31, 2013. Gross Refinery Margins Gross refinery margin per produced barrel decreased 13% from $15.99 for the year ended December 31, 2013 to $13.98 for the year ended December 31, 2014. This was due to a decrease in average per barrel sales prices for refined products sold, partially offset by decreased crude oil and feedstock prices for the current year. Gross refinery margin per produced barrel does not include the non-cash effects of lower of cost or market inventory valuation adjustments and depreciation and amortization. See “Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles” following Item 7A of Part II of this Form 10-K for a reconciliation to the income statement of prices of refined products sold and cost of products purchased. Operating Expenses Operating expenses, exclusive of depreciation and amortization, increased 5% from $1,090.9 million for the year ended December 31, 2013 to $1,144.9 million for the year ended December 31, 2014 due principally to higher year-over-year repair and maintenance and fuel costs and increased environmental accruals, partially offset by $31.7 million in pension settlement costs incurred during 2013. For the years ended December 31, 2014 and 2013, operating expenses include $103.4 million and $95.7 million, respectively, in costs attributable to HEP operations. General and Administrative Expenses General and administrative expenses decreased 10% from $128.0 million for the year ended December 31, 2013 to $114.6 million for the year ended December 31, 2014 due principally to lower incentive compensation expense during the current year, and the effects of $4.5 million in pension settlement costs incurred in 2013. For the years ended December 31, 2014 and 2013, general and administrative expenses include $8.5 million and $9.4 million, respectively, in costs attributable to HEP operations. Depreciation and Amortization Expenses Depreciation and amortization increased 20% from $303.4 million for the year ended December 31, 2013 to $363.4 million for the year ended December 31, 2014. The increase was due principally to depreciation and amortization attributable to capitalized improvement projects, capitalized refinery turnaround costs and accelerated depreciation of assets no longer in operation. For the years ended December 31, 2014 and 2013, depreciation and amortization expenses include $60.5 million and $64.7 million, respectively, in costs attributable to HEP operations. Interest Income Interest income for the year ended December 31, 2014 was $4.4 million compared to $5.6 million for the year ended December 31, 2013. This decrease was due to lower investment levels in marketable debt securities during the current year period. Interest Expense Interest expense was $43.6 million for the year ended December 31, 2014 compared to $68.1 million for the year ended December 31, 2013. This decrease was due to lower year-over-year debt levels. For the years ended December 31, 2014 and 2013, interest expense included $36.1 million and $46.8 million, respectively, in interest costs attributable to HEP operations. 37 Table of Content Loss on Early Extinguishment of Debt In March 2014, HEP redeemed its $150.0 million aggregate principal amount of 8.25% senior notes maturing March 2018 at a redemption cost of $156.2 million, at which time it recognized a $7.7 million early extinguishment loss consisting of a $6.2 million debt redemption premium and unamortized discount and financing costs of $1.5 million. In June 2013, we redeemed our $286.8 million aggregate principal amount of 9.875% senior notes maturing June 2017 at a redemption cost of $301.0 million, at which time we recognized a $22.1 million early extinguishment loss consisting of a $14.2 million debt redemption premium and an unamortized discount of $7.9 million. Income Taxes For the year ended December 31, 2014, we recorded income tax expense of $141.2 million compared to $391.6 million for the year ended December 31, 2013. This decrease was due principally to lower pre-tax earnings during the year ended December 31, 2014 compared to 2013. Our effective tax rates, before consideration of earnings attributable to the noncontrolling interest, were 30.2% and 33.8% for the years ended December 31, 2014 and 2013, respectively. Results of Operations – Year Ended December 31, 2013 Compared to Year Ended December 31, 2012 Summary Net income attributable to HollyFrontier stockholders for the year ended December 31, 2013 was $735.8 million ($3.66 per basic and $3.64 per diluted share), a $991.4 million decrease compared to $1,727.2 million ($8.41 per basic and $8.38 per diluted share) for the year ended December 31, 2012. Net income decreased due principally to a year-over-year decrease in refining margins, refinery downtime and pension settlement and debt extinguishment charges. Refinery gross margins for the year ended December 31, 2013 decreased to $15.99 per produced barrel from $24.89 for the year ended December 31, 2012. Sales and Other Revenues Sales and other revenues increased slightly from $20,090.7 million for the year ended December 31, 2012 to $20,160.6 million for the year ended December 31, 2013 due to higher refined product sales volumes, partially offset by a decrease in year-over- year sales prices. The average sales price we received per produced barrel sold decreased 3% from $119.48 for the year ended December 31, 2012 to $115.60 for the year ended December 31, 2013. Refined product sales volumes for 2013 reflected higher volumes of purchased products, comprising 8% of total refined products sales compared to 3% for the year ended December 31, 2012 due to a decrease in refinery production and corresponding sales volumes of produced product as a result of planned turnaround and maintenance projects at our refineries and other unplanned refinery outages during 2013. Sales and other revenues for the years ended December 31, 2013 and 2012 include $53.4 million and $47.6 million, respectively, in HEP revenues attributable to pipeline and transportation services provided to unaffiliated parties. Cost of Products Sold Cost of products sold increased 10% from $15,840.6 million for the year ended December 31, 2012 to $17,392.2 million for the year ended December 31, 2013, due principally to higher refined product sales volumes and crude costs for 2013. The sales volume increase is attributable to higher sales volumes of purchased products caused in part, by planned turnaround projects and unplanned refinery outages during the year ended December 31, 2013. The average price we paid per barrel for crude oil and feedstocks and the transportation costs of moving the finished products to the market place increased 5% from $94.59 for the year ended December 31, 2012 to $99.61 for the year ended December 31, 2013. Gross Refinery Margins Gross refinery margin per produced barrel decreased 36% from $24.89 for the year ended December 31, 2012 to $15.99 for the year ended December 31, 2013. This was due to a decrease in average per barrel sales prices for refined products sold combined with increased crude oil and feedstock prices for 2013. Gross refinery margin per produced barrel does not include the effects of depreciation and amortization. Operating Expenses Operating expenses, exclusive of depreciation and amortization, increased 10% from $995.0 million for the year ended December 31, 2012 to $1,090.9 million for the year ended December 31, 2013 due principally to higher repair and maintenance and fuel costs during 2013 and $31.7 million in pension settlement costs, partially offset by a decrease in environmental remediation costs. For the years ended December 31, 2013 and 2012, operating expenses include $95.7 million and $88.9 million, respectively, in costs attributable to HEP operations. 38 Table of Content General and Administrative Expenses General and administrative expenses were $128.0 million and $128.1 million for the years ended December 31, 2013 and 2012, respectively. For the years ended December 31, 2013 and 2012, general and administrative expenses include $9.4 million and $5.3 million, respectively, in costs attributable to HEP operations. Depreciation and Amortization Expenses Depreciation and amortization increased 25% from $242.9 million for the year ended December 31, 2012 to $303.4 million for the year ended December 31, 2013. The increase was due principally to depreciation and amortization attributable to capitalized improvement projects and capitalized refinery turnaround costs. For the years ended December 31, 2013 and 2012, depreciation and amortization expenses include $64.7 million and $57.8 million, respectively, in costs attributable to HEP operations. Interest Income Interest income for the year ended December 31, 2013 was $5.6 million compared to $4.8 million for the year ended December 31, 2012. This increase was due to interest received on increased investments in marketable debt securities during 2013. Interest Expense Interest expense was $68.1 million for the year ended December 31, 2013 compared to $104.2 million for the year ended December 31, 2012. This decrease was due to lower year-over-year debt levels principally as a result of the redemption of our $286.8 million 9.875% senior notes in June 2013 and $200 million 8.5% senior notes in September 2012. For the years ended December 31, 2013 and 2012, interest expense included $46.8 million and $57.2 million, respectively, in interest costs attributable to HEP operations. Loss on Early Extinguishment of Debt In June 2013, we redeemed our $286.8 million aggregate principal amount of 9.875% senior notes maturing June 2017 at a redemption cost of $301.0 million, at which time we recognized a $22.1 million early extinguishment loss consisting of a $14.2 million debt redemption premium and an unamortized discount of $7.9 million. Income Taxes For the year ended December 31, 2013, we recorded income tax expense of $391.6 million compared to $1,028.0 million for the year ended December 31, 2012. This decrease was due principally to lower pre-tax earnings during the year ended December 31, 2013 compared to 2012. Our effective tax rates, before consideration of earnings attributable to the noncontrolling interest, were 33.8% and 36.9% for the years ended December 31, 2013 and 2012, respectively. LIQUIDITY AND CAPITAL RESOURCES HollyFrontier Credit Agreement On July 1, 2014, we entered into a new $1 billion senior unsecured revolving credit facility maturing in July 2019 (the “HollyFrontier Credit Agreement”) and contemporaneously terminated our previous $1 billion senior secured revolving credit agreement. The HollyFrontier Credit Agreement may be used for revolving credit loans and letters of credit from time to time and is available to fund general corporate purposes. Indebtedness under the HollyFrontier Credit Agreement is recourse to HollyFrontier and guaranteed by certain of our wholly-owned subsidiaries. At December 31, 2014, we were in compliance with all covenants, had no outstanding borrowings and had outstanding letters of credit totaling $4.7 million under the HollyFrontier Credit Agreement. HEP Credit Agreement HEP has a $650 million senior secured revolving credit facility that matures in November 2018 (the “HEP Credit Agreement”) and is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. It is also available to fund letters of credit up to a $50 million sub-limit. At December 31, 2014, HEP was in compliance with all of its covenants, had outstanding borrowings of $571.0 million and no outstanding letters of credit under the HEP Credit Agreement. See Note 11 "Debt" in the Notes to Consolidated Financial Statements for additional information on our debt instruments. 39 Table of Content Liquidity We believe our current cash and cash equivalents, along with future internally generated cash flow and funds available under our credit facilities will provide sufficient resources to fund currently planned capital projects and our liquidity needs for the foreseeable future. In addition, components of our growth strategy include construction of new refinery processing units and the expansion of existing units at our facilities and selective acquisition of complementary assets for our refining operations intended to increase earnings and cash flow. As of December 31, 2014, our cash, cash equivalents and investments in marketable securities totaled $1.0 billion. We consider all highly-liquid instruments with a maturity of three months or less at the time of purchase to be cash equivalents. Cash equivalents are stated at cost, which approximates market value. These primarily consist of investments in conservative, highly-rated instruments issued by financial institutions, government and corporate entities with strong credit standings and money market funds. In September 2014, our Board of Directors approved a $500 million share repurchase program authorizing us to repurchase common stock in the open market or through privately negotiated transactions. As of December 31, 2014, we had remaining authorization to repurchase up to $444.4 million under this stock repurchase program. In February 2015, our Board of Directors approved a $500 million share repurchase program, which replaced all existing share repurchase programs including approximately $425.0 million remaining under the existing $500 million share repurchase program. The timing and amount of stock repurchases will depend on market conditions, corporate, regulatory and other relevant considerations. This program may be discontinued at any time by our Board of Directors. In addition, we are authorized by our Board of Directors to repurchase shares in an amount sufficient to offset shares issued under our compensation programs. Cash and cash equivalents decreased $372.1 million for the year ended December 31, 2014. Net cash used for investing and financing activities of $292.3 million and $838.4 million, respectively, exceeded net cash provided by operating activities of $758.6 million. Working capital decreased by $690.4 million during the year ended December 31, 2014.

Cash expenditures for properties, plants and equipment for 2014 increased to $564.8 million from $425.1 million for the same period in 2013. These include HEP capital expenditures of $79.8 million and $51.9 million for the years ended December 31, 2014 and 2013, respectively. We received proceeds of $16.6 million and $7.8 million from the sale of assets during the years ended December 31, 2014 and 2013, respectively. For the year ended December 31, 2013, we acquired trucking operations for $11.3 million. Also for the years ended December 31, 2014 and 2013, we invested $1,025.6 million and $935.5 million, respectively, in marketable securities and received proceeds of $1,276.4 million and $846.1 million, respectively, from the sale or maturity of marketable securities. Year Ended December 31, 2013 Compared to Year Ended December 31, 2012 Net cash flows used for investing activities were $526.7 million for the year ended December 31, 2013 compared to $711.1 million for the year ended December 31, 2012, a decrease of $184.4 million.

In addition, for the year ended December 31, 2013, we received proceeds of $7.8 million from the sale of property and equipment and acquired trucking operations for $11.3 million. Also for the years ended December 31, 2013 and 2012, we invested $935.5 million and $671.6 million, respectively, in marketable securities and received proceeds of $846.1 million and $297.7 million, respectively, from the sale or maturity of marketable securities. Planned Capital Expenditures HollyFrontier Corporation Each year our Board of Directors approves our annual capital budget which includes specific projects that management is authorized to undertake. Additionally, when conditions warrant or as new opportunities arise, additional projects may be approved. The funds appropriated for a particular capital project may be expended over a period of several years, depending on the time required to complete the project. Therefore, our planned capital expenditures for a given year consist of expenditures appropriated in that year’s capital budget plus expenditures for projects appropriated in prior years which have not yet been completed. Our appropriated capital budget for 2015 is $137.0 million including both sustaining capital and major capital projects. We expect to spend approximately $600.0 million to $650.0 million in cash for capital projects appropriated in 2015 and prior years. In addition, we expect to spend approximately $45.0 million on refinery turnarounds and $27.0 million on tank work. Refinery turnaround spending is amortized over the useful life of the turnaround. Our new capital appropriation for 2015 and expected cash spending is as follows: New Appropriation Expected Cash Spending Range Location: El Dorado Tulsa Navajo Cheyenne Woods Cross Corporate and Other Total Type: Sustaining Reliability and Growth Compliance and Safety Total (In millions) $ 145.0 – $ 97.0 – 37.0 – 94.0 – 208.0 – 19.0 – 17.0 43.0 19.0 25.0 14.0 19.0 137.0 $ 600.0 – $ 93.0 13.0 31.0 $ 113.0 – $ 312.0 – 175.0 – 137.0 $ 600.0 – $ 157.0 105.0 40.0 102.0 225.0 21.0 650.0 123.0 338.0 189.0 650.0 $ $ $ $ 41 Table of Content A significant portion of our current capital spending is associated with compliance-oriented capital improvements. This spending is required due to existing consent decrees (for projects including FCC unit flue gas scrubbers and tail gas treatment units), federal fuels regulations (particularly, MSAT2 which mandates a reduction in the benzene content of blended gasoline), refinery waste water treatment improvements and other similar initiatives. Our refinery operations and related emissions are highly regulated at both federal and state levels, and we invest in our facilities as needed to remain in compliance with these standards. Additionally, when faced with new emissions or fuels standards, we seek to execute projects that facilitate compliance and also improve the operating costs and / or yields of associated refining processes. El Dorado Refinery Capital projects at the El Dorado Refinery include naphtha fractionation and an additional hydrogen plant. They also include the installation of an FCC gasoline hydrotreater in order to meet Tier 3 gasoline requirements. Continuing project work is planned to include upgrades to the crude unit desalter and a new tail gas treatment unit to reduce air emissions in compliance with the El Dorado Refinery's existing EPA consent decree. Tulsa Refineries Capital spending for the Tulsa Refineries in 2015 includes previously approved capital appropriations for numerous infrastructure upgrades, including a project to improve FCC yields. Spending on maintenance capital items and general improvements continues at an elevated level at the Tulsa Refineries due to lower maintenance capital expenditures made prior to HollyFrontier's purchase of the facilities. Navajo Refinery The Navajo Refinery capital spending in 2015 will be principally directed towards previously approved capital appropriations as well as maintenance capital spending. Included among previously approved capital projects is a $25.0 million upgrade to the Navajo Refinery's waste water treatment system. Cheyenne Refinery We are continuing with our previously approved plan to install a new hydrogen plant at the Cheyenne Refinery. The hydrogen plant, along with a now-completed naphtha fractionation project, is anticipated to allow us to reduce benzene content in Cheyenne gasoline production, while at the same time improving the refinery's overall liquid yields and light oils production. Previously appropriated projects still underway at Cheyenne include wastewater treatment plant improvements, a flue gas scrubber for the FCC unit to reduce air emissions and a redundant tail gas unit associated with the sulfur recovery process. Woods Cross Refinery Engineering and construction continue on our previously announced expansion project to increase planned processing capacity to 45,000 BPSD, at a cost currently expected to range between $350.0 million and $400.0 million. On November 18, 2013, the Utah Division of Air Quality issued a revised air quality permit (the “Approval Order”) authorizing the expansion. On December 18, 2013, two local environmental groups filed an administrative appeal challenging the issuance of the Approval Order and seeking a stay of the Approval Order. On March 25, 2014, the administrative law judge (“ALJ”) issued a recommendation to the Executive Director of the Utah Department of Environmental Quality (the “DEQ”) recommending that the motion to stay the Approval Order be denied. On May 8, 2014, the Executive Director of the DEQ issued an order approving the ALJ's recommendation and denying the motion to stay the Approval Order. The environmental groups did not file an appeal of this denial. The merits briefing and oral argument were completed in September 2014. On October 1, 2014, Holly Refining & Marketing Company - Woods Cross LLC, our wholly-owned subsidiary, and the State of Utah jointly submitted proposed findings of fact and conclusions of law to the ALJ. The expansion is expected to be completed in the fourth quarter of 2015. This project work includes a new rail loading rack for intermediates and finished products associated with refining waxy crude oil. The expansion, and expected completion timeline and cost, are subject to the Woods Cross refinery successfully obtaining the Approval Order. Regulatory compliance items or other presently existing or future environmental regulations / consent decrees could cause us to make additional capital investments beyond those described above and incur additional operating costs to meet applicable requirements, including those related to recently promulgated Federal Tier 3 gasoline standards. HEP Each year the Holly Logistic Services, L.L.C. board of directors approves HEP’s annual capital budget, which specifies capital projects that HEP management is authorized to undertake. Additionally, at times when conditions warrant or as new opportunities arise, special projects may be approved. The funds allocated for a particular capital project may be expended over a period of several years, depending on the time required to complete the project. Therefore, HEP’s planned capital expenditures for a given year consist of expenditures approved for capital projects included in its current year capital budget as well as, in certain cases, expenditures approved for capital projects in capital budgets for prior years. The 2015 HEP capital budget is comprised of $10.0 million for maintenance capital expenditures and $73.0 million for expansion capital expenditures. 42 Table of Content Cash Flows – Financing Activities Year Ended December 31, 2014 Compared to Year Ended December 31, 2013 Net cash flows used for financing activities were $838.4 million for the year ended December 31, 2014 compared to $1,160.0 million for the year ended December 31, 2013, a decrease of $321.6 million.

Interest on the HEP Credit Agreement debt is based on the weighted average rate of 2.15% at December 31, 2014. CRITICAL ACCOUNTING POLICIES Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities as of the date of the financial statements. Actual results may differ from these estimates under different assumptions or conditions. We consider the following policies to be the most critical to understanding the judgments that are involved and the uncertainties that could impact our results of operations, financial condition and cash flows. For additional information, see Note 1 “Description of Business and Summary of Significant Accounting Policies” in the Notes to Consolidated Financial Statements. Variable Interest Entities HEP is a VIE as defined under GAAP. A VIE is a legal entity whose equity owners do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the equity holders lack the power, through voting rights, to direct the activities that most significantly impact the entity's financial performance. As the general partner of HEP, we have the sole ability to direct the activities of HEP that most significantly impact HEP's financial performance, and therefore we consolidate HEP. Derivative Instruments We have commodity price swap, interest rate swap and NYMEX futures contracts that are measured at fair value and recognized as other assets or liabilities in our consolidated balance sheets. Changes in fair value to derivative instruments are recognized in earnings unless specific hedge accounting criteria is met. Derivatives meeting certain hedge accounting criteria are designated as “accounting hedges” and changes in fair value are recorded directly to other comprehensive income. These gains or losses are reclassified to earnings as the hedging instruments mature. Also, on a quarterly basis, hedge ineffectiveness on our accounting hedges is measured by comparing the change in fair value of the derivative contracts against the expected future cash inflows/ outflows on the respective transaction being hedged. Any hedge ineffectiveness is recognized in earnings. See Note 12 “Derivative Instruments and Hedging Activities” in the Notes to Consolidated Financial Statements. Inventory Valuation Our crude oil and refined product inventories are stated at the lower of cost or market. Cost is determined using the LIFO inventory valuation methodology and market is determined using current replacement costs. Under the LIFO method, the most recently incurred costs are charged to cost of sales and inventories are valued at the earliest acquisition costs. In periods of rapidly declining prices, LIFO inventories may have to be written down to market value due to the higher costs assigned to LIFO layers in prior periods. In addition, the use of the LIFO inventory method may result in increases or decreases to cost of sales in years when inventory volumes decline and result in charging cost of sales with LIFO inventory costs generated in prior periods. At December 31, 2014, market values had fallen below historical LIFO inventory costs and, as a result, we recognized a non-cash pretax loss of $397.5 million. Such losses are subject to reversal in subsequent periods, not to exceed historical LIFO costs, if prices recover. Deferred Maintenance Costs Our refinery units require regular major maintenance and repairs that are commonly referred to as “turnarounds.” Catalysts used in certain refinery processes also require routine “change-outs.” The required frequency of the maintenance varies by unit and by catalyst, but generally is every two to five years. In order to minimize downtime during turnarounds, we often utilize contract labor as well as our maintenance personnel on a continuous 24 hour basis. Whenever possible, turnarounds are scheduled so that 44 Table of Content some units continue to operate while others are down for maintenance. We record the costs of turnarounds as deferred charges and amortize the deferred costs over the expected periods of benefit. Long-lived Assets We calculate depreciation and amortization based on estimated useful lives of our assets. When assets are placed into service, we make estimates with respect to their useful lives that we believe are reasonable. However, factors such as competition, regulation or environmental matters could cause us to change our estimates, thus impacting the future calculation of depreciation and amortization. We evaluate long-lived assets for potential impairment by identifying whether indicators of impairment exist and, if so, assessing whether the long-lived assets are recoverable from estimated future undiscounted cash flows. The actual amount of impairment loss, if any, to be recorded is equal to the amount by which a long-lived asset's carrying value exceeds its fair value, which is generally determined under an income approach using forecasted cash flows associated with the underlying asset. Estimates of future cash flows require subjective assumptions with regard to future operating results and actual results could differ from those estimates. No impairments of long-lived assets were recorded during the years ended December 31, 2014, 2013 and 2012. Goodwill We have goodwill that primarily arose from our merger with Frontier Oil Corporation on July 1, 2011. Goodwill represents the excess of the cost of an acquired entity over the fair value of the assets acquired and liabilities assumed. Goodwill is not subject to amortization and is tested annually or more frequently if events or circumstances indicate the possibility of impairment. We performed our annual goodwill impairment testing as of July 1, 2014, which entailed an assessment of our reporting unit fair values relative to their respective carrying values that were derived using a combination of both income and market approaches. Our income approach utilizes the discounted future expected cash flows and has an 80% weighting. Our market approach, which includes both the guideline public company and guideline transaction methods, each having a 10% weighting, utilizes pricing multiples derived from historical market transactions of similar assets. Our discounted cash flows reflect estimates of future cash flows based on both historical and forward crack-spreads, forecasted production levels, operating costs and capital expenditures. Our goodwill is allocated by reporting unit as follows: El Dorado, $1.7 billion; Cheyenne, $0.3 billion; and HEP, $0.3 billion. Based on our testing as of July 1, 2014, the fair value of our Cheyenne reporting unit exceeded its carrying cost by slightly less than 20%, and the fair value of our El Dorado and HEP reporting units exceeded their respective carrying values by a much larger percentage. There were no impairments of goodwill during the years December 31, 2014, 2013 and 2012. Historically, the refining industry has experienced significant fluctuations in operating results over an extended business cycle including changes in prices of crude oil and refined products, changes in operating costs including natural gas and higher costs of complying with government regulations. It is reasonably possible that at some future downturn in refining operations that the goodwill related to our Cheyenne Refinery will be determined to be impaired. A prolonged operating margin decrease of 8% to 10% could potentially result in impairment to goodwill allocated to our Cheyenne reporting unit and such impairment charges could be significant. Environmental Costs Environmental costs are charged to operating expenses if they relate to an existing condition caused by past operations and do not contribute to current or future revenue generation. Liabilities are recorded when site restoration and environmental remediation, cleanup and other obligations are either known or considered probable and can be reasonably estimated. Such estimates are undiscounted and require judgment with respect to costs, time frame and extent of required remedial and clean-up activities and are subject to periodic adjustments based on currently available information. Recoveries of environmental costs through insurance, indemnification arrangements or other sources are included in other assets to the extent such recoveries are considered probable. Contingencies We are subject to proceedings, lawsuits and other claims related to environmental, labor, product and other matters. We are required to assess the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies is made after careful analysis of each individual issue. The required reserves may change in the future due to new developments in each matter or changes in approach such as a change in settlement strategy in dealing with these matters. Pursuant to the 2007 Energy Independence and Security Act, the EPA promulgated the RFS2 regulations reflecting the increased volume of renewable fuels mandated to be blended into the nation's fuel supply. The regulations, in part, require refiners to add annually increasing amounts of “renewable fuels” to their petroleum products or purchase credits, known as RINs, in lieu of such blending. The EPA has not yet finalized the 2014 percentage standards under its RFS2 program. The estimated quantity of renewable fuels or RINs that we are required to purchase and that have been accrued for as of and for the year ended December 31, 2014 are based on quantities proposed by the EPA in November 2013. 45 Table of Content New Accounting Pronouncements Revenue Recognition In May 2014, an accounting standard update (ASU 2014-09, “Revenue from Contracts with Customers”) was issued requiring revenue to be recognized when promised goods or services are transferred to customers in an amount that reflects the expected consideration for these goods or services. This standard is effective January 1, 2017, and we are evaluating the impact of this standard. RISK MANAGEMENT We use certain strategies to reduce some commodity price and operational risks. We do not attempt to eliminate all market risk exposures when we believe that the exposure relating to such risk would not be significant to our future earnings, financial position, capital resources or liquidity or that the cost of eliminating the exposure would outweigh the benefit. Commodity Price Risk Management Our primary market risk is commodity price risk. We are exposed to market risks related to the volatility in crude oil and refined products, as well as volatility in the price of natural gas used in our refining operations. We periodically enter into derivative contracts in the form of commodity price swaps and futures contracts to mitigate price exposure with respect to: • • • • • our inventory positions; natural gas purchases; costs of crude oil and related grade differentials; prices of refined products; and our refining margins. As of December 31, 2014, we have the following notional contract volumes related to all outstanding derivative contracts used to mitigate commodity price risk: Contract Description Natural gas price swap - long Natural gas price swap - short WTI price swap - long Ultra-low sulfur diesel price swap - short 4,380,000 4,380,000 WTI basis spread price swap - long NYMEX futures (WTI) - short 4,015,000 4,015,000 2,058,000 2,058,000 Notional Contract Volumes by Year of Maturity Total Outstanding Notional 2015 2016 2017 Unit of Measure 57,600,000 19,200,000 19,200,000 19,200,000 MMBTU 28,800,000 9,600,000 9,600,000 9,600,000 MMBTU 5,475,000 5,475,000 — — — — — Barrels — Barrels — Barrels — Barrels The following sensitivity analysis provides the hypothetical effects of market price fluctuations to the commodity positions hedged under our derivative contracts: Commodity-based Derivative Contracts 2014 2013 Hypothetical 10% change in underlying commodity prices $ (In thousands) 11,947 $ 69,228 Estimated Change in Fair Value at December 31, Interest Rate Risk Management HEP uses interest rate swaps to manage its exposure to interest rate risk. As of December 31, 2014, HEP had three interest rate swap contracts that hedge its exposure to the cash flow risk caused by the effects of LIBOR changes on $305.0 million in credit agreement advances. The first interest rate swap effectively converts $155.0 million of LIBOR based debt to fixed-rate debt having an interest rate of 0.99% plus an applicable margin of 2.00% as of December 31, 2014, which equaled an effective interest rate of 2.99%. This swap matures in February 2016. HEP has two additional interest rate swaps with identical terms which effectively convert $150.0 million of LIBOR based debt to fixed-rate debt having 46 Table of Content an interest rate of 0.74% plus an applicable margin of 2.00% as of December 31, 2014, which equaled an effective interest rate of 2.74%. Both of these swap contracts mature in July 2017. These swap contracts have been designated as cash flow hedges. The market risk inherent in our fixed-rate debt is the potential change arising from increases or decreases in interest rates as discussed below. For the fixed rate HollyFrontier Senior Notes and HEP Senior Notes, changes in interest rates will generally affect fair value of the debt, but not earnings or cash flows. The outstanding principal, estimated fair value and estimated change in fair value (assuming a hypothetical 10% change in the yield-to-maturity rates) for these debt instruments as of December 31, 2014 is presented below: HollyFrontier Senior Notes HEP Senior Notes Outstanding Principal Estimated Fair Value (In thousands) Estimated Change in Fair Value $ $ 150,000 300,000 $ $ 155,250 291,000 $ $ 3,100 8,495 For the variable rate HEP Credit Agreement, changes in interest rates would affect cash flows, but not the fair value. At December 31, 2014, outstanding borrowings under the HEP Credit Agreement were $571.0 million. By means of its cash flow hedges, HEP has effectively converted the variable rate on $305.0 million of outstanding principal to a weighted average fixed rate of 2.87%. For the remaining unhedged Credit Agreement borrowings of $266.0 million, a hypothetical 10% change in interest rates applicable to the HEP Credit Agreement would not materially affect cash flows. At December 31, 2014, our marketable securities included investments in investment grade, highly-liquid investments with maturities generally not greater than one year from the date of purchase and hence the interest rate market risk implicit in these investments is low. Due to the short-term nature of our cash and cash equivalents, a hypothetical 10% increase in interest rates would not have a material effect on the fair market value of our portfolio. Since we have the ability to liquidate this portfolio, we do not expect our operating results or cash flows to be materially affected by the effect of a sudden change in market interest rates on our investment portfolio. Our operations are subject to hazards of petroleum processing operations, including fire, explosion and weather-related perils. We maintain various insurance coverages, including business interruption insurance, subject to certain deductibles. We are not fully insured against certain risks because such risks are not fully insurable, coverage is unavailable, or premium costs, in our judgment, do not justify such expenditures. Financial information is reviewed on the counterparties in order to review and monitor their financial stability and assess their ongoing ability to honor their commitments under the derivative contracts. We have not experienced, nor do we expect to experience, any difficulty in the counterparties honoring their commitments. We have a risk management oversight committee consisting of members from our senior management. This committee oversees our risk enterprise program, monitors our risk environment and provides direction for activities to mitigate identified risks that may adversely affect the achievement of our goals. Item 7A. Quantitative and Qualitative Disclosures About Market Risk See “Risk Management” under “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles Reconciliations of earnings before interest, taxes, depreciation and amortization (“EBITDA”) to amounts reported under generally accepted accounting principles in financial statements. Earnings before interest, taxes, depreciation and amortization, which we refer to as EBITDA, is calculated as net income attributable to HollyFrontier stockholders plus (i) interest expense, net of interest income, (ii) income tax provision, and (iii) depreciation and amortization. EBITDA is not a calculation provided for under GAAP; however, the amounts included in the EBITDA calculation are derived from amounts included in our consolidated financial statements. EBITDA should not be considered as an alternative to net income or operating income as an indication of our operating performance or as an alternative to operating cash flow as a 47 Table of Content measure of liquidity. EBITDA is not necessarily comparable to similarly titled measures of other companies. EBITDA is presented here because it is a widely used financial indicator used by investors and analysts to measure performance. EBITDA is also used by our management for internal analysis and as a basis for financial covenants. Set forth below is our calculation of EBITDA.

Reconciliations of refinery operating information (non-GAAP performance measures) to amounts reported under generally accepted accounting principles in financial statements. Refinery gross margin and net operating margin are non-GAAP performance measures that are used by our management and others to compare our refining performance to that of other companies in our industry. We believe these margin measures are helpful to investors in evaluating our refining performance on a relative and absolute basis. Refinery gross margin per barrel is the difference between average net sales price and average cost of products per barrel of produced refined products. Net operating margin per barrel is the difference between refinery gross margin and refinery operating expenses per barrel of produced refined products. These two margins do not include the non-cash effects of lower of cost or market inventory valuation adjustments or depreciation and amortization. Each of these component performance measures can be reconciled directly to our consolidated statements of income. Other companies in our industry may not calculate these performance measures in the same manner. Refinery Gross and Net Operating Margins Below are reconciliations to our consolidated statements of income for (i) net sales, cost of products (exclusive of lower of cost or market inventory valuation adjustment) and operating expenses, in each case averaged per produced barrel sold, and (ii) net operating margin and refinery gross margin. Due to rounding of reported numbers, some amounts may not calculate exactly. 48 Table of Content Reconciliation of produced product sales to total sales and other revenues Consolidated Average sales

Financial Statements and Supplementary Data MANAGEMENT'S REPORT ON ITS ASSESSMENT OF THE COMPANY'S INTERNAL CONTROL OVER FINANCIAL REPORTING Management of HollyFrontier Corporation (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Management assessed the Company's internal control over financial reporting as of December 31, 2014 using the criteria for effective control over financial reporting established in “Internal Control - Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this assessment, management concludes that, as of December 31, 2014, the Company maintained effective internal control over financial reporting. The Company's independent registered public accounting firm has issued an attestation report on the effectiveness of the Company's internal control over financial reporting as of December 31, 2014. That report appears on page 53. 51 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Stockholders of HollyFrontier Corporation We have audited HollyFrontier Corporation's internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), (the “COSO criteria”). HollyFrontier Corporation's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on its Assessment of the Company's Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, HollyFrontier Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on the COSO criteria. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of HollyFrontier Corporation as of December 31, 2014 and 2013, and the related consolidated statements of income, comprehensive income, cash flows and equity for each of the three years in the period ended December 31, 2014 and our report dated February 25, 2015 expressed an unqualified opinion thereon. /s/ ERNST & YOUNG LLP Dallas, Texas February 25, 2015 52 Index to Consolidated Financial Statements Report of Independent Registered Public Accounting Firm Consolidated Balance Sheets at December 31, 2014 and 2013 Consolidated Statements of Income for the years ended December 31, 2014, 2013 and 2012 Consolidated Statements of Comprehensive Income for the years ended December 31, 2014, 2013 and 2012 Consolidated Statements of Cash Flows for the years ended December 31, 2014, 2013 and 2012 Consolidated Statements of Equity for the years ended December 31, 2014, 2013 and 2012 Notes to Consolidated Financial Statements Page Reference 54 55 56 57 58 59 60 53 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Stockholders of HollyFrontier Corporation We have audited the accompanying consolidated balance sheets of HollyFrontier Corporation (the “Company”) as of December 31, 2014 and 2013, and the related consolidated statements of income, comprehensive income, cash flows and equity for each of the three years in the period ended December 31, 2014. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of HollyFrontier Corporation at December 31, 2014 and 2013, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2014, in conformity with U.S. generally accepted accounting principles. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), HollyFrontier Corporation's internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 25, 2015 expressed an unqualified opinion thereon.

Business: References herein to HollyFrontier Corporation (“HollyFrontier”) include HollyFrontier and its consolidated subsidiaries. In accordance with the Securities and Exchange Commission’s (“SEC”) “Plain English” guidelines, this Annual Report on Form 10-K has been written in the first person. In these financial statements, the words “we,” “our,” “ours” and “us” refer only to HollyFrontier and its consolidated subsidiaries or to HollyFrontier or an individual subsidiary and not to any other person, with certain exceptions. Generally, the words “we,” “our,” “ours” and “us” include Holly Energy Partners, L.P. (“HEP”) and its subsidiaries as consolidated subsidiaries of HollyFrontier, unless when used in disclosures of transactions or obligations between HEP and HollyFrontier or its other subsidiaries. These financial statements contain certain disclosures of agreements that are specific to HEP and its consolidated subsidiaries and do not necessarily represent obligations of HollyFrontier. When used in descriptions of agreements and transactions, “HEP” refers to HEP and its consolidated subsidiaries. We are principally an independent petroleum refiner that produces high-value light products such as gasoline, diesel fuel, jet fuel, specialty lubricant products, and specialty and modified asphalt. We own and operate petroleum refineries that serve markets throughout the Mid-Continent, Southwest and Rocky Mountain regions of the United States. As of December 31, 2014, we: • • • • owned and operated a petroleum refinery in El Dorado, Kansas (the “El Dorado Refinery”), two refinery facilities located in Tulsa, Oklahoma (collectively, the “Tulsa Refineries”), a refinery in Artesia, New Mexico that is operated in conjunction with crude oil distillation and vacuum distillation and other facilities situated 65 miles away in Lovington, New Mexico (collectively, the “Navajo Refinery”), a refinery located in Cheyenne, Wyoming (the “Cheyenne Refinery”) and a refinery in Woods Cross, Utah (the “Woods Cross Refinery”); owned and operated NK Asphalt Partners (“NK Asphalt”) which operates various asphalt terminals in Arizona, New Mexico and Oklahoma; owned a 50% interest in Sabine Biofuels II, LLC (“Sabine Biofuels”), a biodiesel production facility located in Port Arthur, Texas; and owned a 39% interest in HEP, a consolidated variable interest entity (“VIE”), which includes our 2% general partner interest. HEP owns and operates logistic assets consisting of petroleum product and crude oil pipelines and terminal, tankage and loading rack facilities that principally support our refining and marketing operations in the Mid-Continent, Southwest and Rocky Mountain regions of the United States and Alon USA, Inc.'s (“Alon”) refinery in Big Spring, Texas. Additionally, HEP owns a 75% interest in UNEV Pipeline, LLC (“UNEV”), which owns a 12-inch refined products pipeline from Salt Lake City, Utah to Las Vegas, Nevada, together with terminal facilities in the Cedar City, Utah and North Las Vegas areas (the “UNEV Pipeline”) and a 25% interest in SLC Pipeline LLC (the “SLC Pipeline”), which owns a 95-mile intrastate pipeline system that serves refineries in the Salt Lake City area. Principles of Consolidation: Our consolidated financial statements include our accounts and the accounts of partnerships and joint ventures that we control through an ownership interest greater than 50% or through a controlling financial interest with respect to variable interest entities. All significant intercompany transactions and balances have been eliminated. Variable Interest Entities: HEP is a VIE as defined under U.S. generally accepted accounting principles (“GAAP”). A VIE is a legal entity whose equity owners do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the equity holders lack the power, through voting rights, to direct the activities that most significantly impact the entity's financial performance, the obligation to absorb the entity's expected losses or rights to expected residual returns. As the general partner of HEP, we have the sole ability to direct the activities of HEP that most significantly impact HEP's financial performance, and therefore we consolidate HEP. Use of Estimates: The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Cash Equivalents: We consider all highly liquid instruments with a maturity of three months or less at the date of purchase to be cash equivalents. Cash equivalents are stated at cost, which approximates market value and are primarily invested in highly-rated instruments issued by government or municipal entities with strong credit standings. 60 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued Marketable Securities: We consider all marketable debt securities with maturities greater than three months at the date of purchase to be marketable securities. Our marketable securities consist of certificates of deposit, commercial paper, corporate debt securities and government and municipal debt securities with the maximum maturity or put date of any individual issue generally not more than two years, while the maximum duration of the portfolio of investments is not greater than one year. These instruments are classified as available-for-sale, and as a result, are reported at fair value. Unrealized gains and losses, net of related income taxes, are reported as a component of accumulated other comprehensive income. Balance Sheet Offsetting: We purchase and sell inventories of crude oil with certain same-parties that are net settled in accordance with contractual net settlement provisions. Our policy is to present such balances on a net basis because it more appropriately presents our economic resources (accounts receivable) and claims against us (accounts payable) and the future cash flows associated with such assets and liabilities. Accounts Receivable: Our accounts receivable consist of amounts due from customers that are primarily companies in the petroleum industry. Credit is extended based on our evaluation of the customer's financial condition, and in certain circumstances collateral, such as letters of credit or guarantees, is required. We reserve for doubtful accounts based on our historical loss experience as well as specific accounts identified as high risk, which historically have been minimal. Credit losses are charged to the allowance for doubtful accounts when an account is deemed uncollectible. Our allowance for doubtful accounts was $2.4 million at December 31, 2014 and 2013. Accounts receivable attributable to crude oil resales generally represent the sell side of excess crude oil sales to other purchasers and / or users in cases when our crude oil supplies are in excess of our immediate needs as well as certain reciprocal buy / sell exchanges of crude oil. At times we enter into such buy / sell exchanges to facilitate the delivery of quantities to certain locations. In many cases, we enter into net settlement agreements relating to the buy/sell arrangements, which may mitigate credit risk. Inventories: Inventories are stated at the lower of cost, using the last-in, first-out (“LIFO”) method for crude oil, unfinished and finished refined products and the average cost method for materials and supplies, or market. Cost, consisting of raw material, transportation and conversion costs, is determined using the LIFO inventory valuation methodology and market is determined using current replacement costs. Under the LIFO method, the most recently incurred costs are charged to cost of sales and inventories are valued at the earliest acquisition costs. In periods of rapidly declining prices, LIFO inventories may have to be written down to market value due to the higher costs assigned to LIFO layers in prior periods. In addition, the use of the LIFO inventory method may result in increases or decreases to cost of sales in years that inventory volumes decline as the result of charging cost of sales with LIFO inventory costs generated in prior periods. An actual valuation of inventory under the LIFO method is made at the end of each year based on the inventory levels at that time. Accordingly, interim LIFO calculations are based on management's estimates of expected year-end inventory levels and are subject to the final year-end LIFO inventory valuation. At December 31, 2014, market values had fallen below historical LIFO inventory costs and, as a result, we recognized a non-cash pretax loss of of $397.5 million. Such losses are subject to reversal in subsequent periods, not to exceed historical LIFO costs, if prices recover. Derivative Instruments: All derivative instruments are recognized as either assets or liabilities in our consolidated balance sheets and are measured at fair value. Changes in the derivative instrument's fair value are recognized in earnings unless specific hedge accounting criteria are met. See Note 12 for additional information. Long-lived assets: We calculate depreciation and amortization based on estimated useful lives of our assets. We evaluate long- lived assets for potential impairment by identifying whether indicators of impairment exist and, if so, assessing whether the long- lived assets are recoverable from estimated future undiscounted cash flows. The actual amount of impairment loss, if any, to be recorded is equal to the amount by which a long-lived asset's carrying value exceeds its fair value, which is generally determined under an income approach using the forecasted cash flows associated with the underlying asset. Estimates of future cash flows require subjective assumptions with regard to future operating results and actual results could differ from those estimates. No impairments of long-lived assets were recorded during the years ended December 31, 2014, 2013 and 2012. 61 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued Asset Retirement Obligations: We record legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development and / or the normal operation of long-lived assets. The fair value of the estimated cost to retire a tangible long-lived asset is recorded as a liability with the associated retirement costs capitalized as part of the asset's carrying amount in the period in which it is incurred and when a reasonable estimate of the fair value of the liability can be made. If a reasonable estimate cannot be made at the time the liability is incurred, we record the liability when sufficient information is available to estimate the liability's fair value. Certain of our refining assets have no recorded liability for asset retirement obligations since the timing of any retirement and related costs are currently indeterminable. Our asset retirement obligations were $19.8 million and $19.1 million at December 31, 2014 and 2013, respectively, which are included in “Other long-term liabilities” in our consolidated balance sheets. Accretion expense was insignificant for the years ended December 31, 2014, 2013 and 2012. Intangibles and Goodwill: Intangible assets are assets (other than financial assets) that lack physical substance. Goodwill represents the excess of the cost of an acquired entity over the fair value of the assets acquired less liabilities assumed. Goodwill acquired in a business combination and intangible assets with indefinite useful lives are not amortized while, intangible assets with finite useful lives are amortized on a straight-line basis. Goodwill and intangible assets not subject to amortization are tested for impairment annually or more frequently if events or changes in circumstances indicate the asset might be impaired. Our analysis entails a comparison of the estimated fair value of these assets that are derived using a combination of both income (discounted future expected net cash flows) and comparable market approaches against their respective carrying values. Estimates of future cash flows and fair value of assets require subjective assumptions with regard to future operating results and actual results could differ from those estimates. In addition to goodwill, our consolidated HEP assets include a third-party transportation agreement that currently generates minimum annual cash inflows of $25.0 million and has an expected remaining term through 2035. The transportation agreement is being amortized on a straight-line basis through 2035 that results in annual amortization expense of $2.0 million. The balance of this transportation agreement was $40.5 million and $42.5 million at December 31, 2014 and 2013, respectively, and is presented net of accumulated amortization of $19.7 million and $17.7 million, respectively, in “Intangibles and other” in our consolidated balance sheets. There were no impairments of intangible assets or goodwill during the years ended December 31, 2014, 2013 and 2012. Investments in Joint Ventures: We consolidate the financial and operating results of joint ventures in which we have an ownership interest of greater than 50% and use the equity method of accounting for investments in which we have a noncontrolling interest. Under the equity method of accounting, we record our pro-rata share of earnings, and contributions to and distributions from joint ventures as adjustments to our investment balance. HEP has a 25% joint venture interest in the SLC Pipeline that is accounted for using the equity method of accounting. As of December 31, 2014, HEP's underlying equity in the SLC Pipeline was $58.9 million compared to its recorded investment balance of $24.5 million, a difference of $34.4 million. This is attributable to the difference between HEP's contributed capital and its allocated equity at formation of the SLC Pipeline. This difference is being amortized as an adjustment to HEP's pro-rata share of earnings. Additionally, we have a 50% ownership interest in Sabine Biofuels, a biofuels production facility. This equity method investment had a carrying balance of $8.5 million at December 31, 2014. Revenue Recognition: Refined product sales and related cost of sales are recognized when products are shipped and title has passed to customers. HEP recognizes pipeline transportation revenues as products are shipped through its pipelines. All revenues are reported inclusive of shipping and handling costs billed and exclusive of any taxes billed to customers. Shipping and handling costs incurred are reported in cost of products sold. Depreciation: Depreciation is provided by the straight-line method over the estimated useful lives of the assets, primarily 20 to 25 years for refining, pipeline and terminal facilities, 10 to 40 years for buildings and improvements, 5 to 30 years for other fixed assets and 5 years for vehicles. 62 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued Cost Classifications: Costs of products sold include the cost of crude oil, other feedstocks, blendstocks and purchased finished products, inclusive of transportation costs. We purchase crude oil that at times exceeds the supply needs of our refineries. Quantities in excess of our needs are sold at market prices to purchasers of crude oil that are recorded on a gross basis with the sales price recorded as revenues and the corresponding acquisition cost as cost of products sold. Additionally, we enter into buy/sell exchanges of crude oil with certain parties to facilitate the delivery of quantities to certain locations that are netted at cost. Operating expenses include direct costs of labor, maintenance materials and services, utilities, marketing expense and other direct operating costs. General and administrative expenses include compensation, professional services and other support costs. Deferred Maintenance Costs: Our refinery units require regular major maintenance and repairs which are commonly referred to as “turnarounds.” Catalysts used in certain refinery processes also require regular “change-outs.” The required frequency of the maintenance varies by unit and by catalyst, but generally is every two to five years. Turnaround costs are deferred and amortized over the period until the next scheduled turnaround. Other repairs and maintenance costs are expensed when incurred. Deferred turnaround and catalyst amortization expense was $96.9 million, $84.8 million and $54.4 million for the years ended December 31, 2014, 2013 and 2012, respectively. Environmental Costs: Environmental costs are charged to operating expenses if they relate to an existing condition caused by past operations and do not contribute to current or future revenue generation. Liabilities are recorded when site restoration and environmental remediation, cleanup and other obligations are either known or considered probable and can be reasonably estimated. Such estimates are undiscounted and require judgment with respect to costs, time frame and extent of required remedial and clean- up activities and are subject to periodic adjustments based on currently available information. Recoveries of environmental costs through insurance, indemnification arrangements or other sources are included in other assets to the extent such recoveries are considered probable. Contingencies: We are subject to proceedings, lawsuits and other claims related to environmental, labor, product and other matters. We are required to assess the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies is made after careful analysis of each individual issue. The required reserves may change in the future due to new developments in each matter or changes in approach such as a change in settlement strategy in dealing with these matters. Income Taxes: Provisions for income taxes include deferred taxes resulting from temporary differences in income for financial and tax purposes, using the liability method of accounting for income taxes. The liability method requires the effect of tax rate changes on current and accumulated deferred income taxes to be reflected in the period in which the rate change was enacted. The liability method also requires that deferred tax assets be reduced by a valuation allowance unless it is more likely than not that the assets will be realized. Potential interest and penalties related to income tax matters are recognized in income tax expense. We believe we have appropriate support for the income tax positions taken and to be taken on our income tax returns and that our accruals for tax liabilities are adequate for all open years based on an assessment of many factors, including past experience and interpretations of tax law applied to the facts of each matter. New Accounting Pronouncements Revenue Recognition In May 2014, an accounting standard update (ASU 2014-09, “Revenue from Contracts with Customers”) was issued requiring revenue to be recognized when promised goods or services are transferred to customers in an amount that reflects the expected consideration for these goods or services. This standard is effective January 1, 2017, and we are evaluating the impact of this standard. 63 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued NOTE 2: Variable Interest Entities Holly Energy Partners HEP, a consolidated VIE, is a publicly held master limited partnership that was formed to acquire, own and operate the petroleum product and crude oil pipeline and terminal, tankage and loading rack facilities that support our refining and marketing operations in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. HEP also owns and operates refined product pipelines and terminals, located primarily in Texas, that serve Alon's refinery in Big Spring, Texas. As of December 31, 2014, we owned a 39% interest in HEP, including the 2% general partner interest. As the general partner of HEP, we have the sole ability to direct the activities that most significantly impact HEP's financial performance, and therefore we consolidate HEP. See Note 20 for supplemental guarantor/non-guarantor financial information, including HEP balances included in these consolidated financial statements. HEP has two primary customers (including us) and generates revenues by charging tariffs for transporting petroleum products and crude oil though its pipelines, by charging fees for terminalling refined products and other hydrocarbons, and storing and providing other services at its storage tanks and terminals. Under our long-term transportation agreements with HEP (discussed further below), we accounted for 83% of HEP’s total revenues for the year ended December 31, 2014. We do not provide financial or equity support through any liquidity arrangements and / or debt guarantees to HEP. HEP has outstanding debt under a senior secured revolving credit agreement and its senior notes. With the exception of the assets of HEP Logistics Holdings, L.P., one of our wholly-owned subsidiaries and HEP’s general partner, HEP’s creditors have no recourse to our other assets. Any recourse to HEP’s general partner would be limited to the extent of HEP Logistics Holdings, L.P.’s assets, which other than its investment in HEP, are not significant. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries. See Note 11 for a description of HEP’s debt obligations. HEP has risk associated with its operations. If a major customer of HEP were to terminate its contracts or fail to meet desired shipping or throughput levels for an extended period of time, revenue would be reduced and HEP could suffer substantial losses to the extent that a new customer is not found. In the event that HEP incurs a loss, our operating results will reflect HEP’s loss, net of intercompany eliminations, to the extent of our ownership interest in HEP at that point in time. UNEV Interest Transaction On July 12, 2012, HEP acquired from us our 75% interest in UNEV. We received consideration consisting of $260.0 million in cash and 1.0 million HEP common units. Transportation Agreements HEP serves our refineries under long-term pipeline and terminal, tankage and throughput agreements expiring from 2019 through 2026. Under these agreements, we pay HEP fees to transport, store and throughput volumes of refined product and crude oil on HEP's pipeline and terminal, tankage and loading rack facilities that result in minimum annual payments to HEP including UNEV (a consolidated subsidiary of HEP). Under these agreements, the agreed upon tariff rates are subject to annual tariff rate adjustments on July 1 at a rate based upon the percentage change in Producer Price Index or Federal Energy Regulatory Commission index. As of December 31, 2014, these agreements result in minimum annualized payments to HEP of $231.6 million. Our transactions with HEP including the acquisition discussed above and fees paid under our transportation agreements with HEP and UNEV are eliminated and have no impact on our consolidated financial statements. HEP's recent common unit issuances (2012 through present) are summarized below: 2013 Issuances In March 2013, HEP closed on a public offering of 1,875,000 of its common units. Additionally, our wholly-owned subsidiary, HollyFrontier Holdings LLC, as a selling unitholder, closed on a public sale of 1,875,000 HEP common units held by it. HEP used net proceeds of $73.4 million to repay indebtedness incurred under its credit facility and for general partnership purposes. 2012 Issuances In July 2012, HEP issued 1.0 million of its common units to us as partial consideration for its purchase of our 75% interest in UNEV. 64 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued As a result of these transactions and resulting HEP ownership changes, we adjusted additional capital and equity attributable to HEP's noncontrolling interest holders to effectively reallocate a portion of HEP's equity among its unitholders. NOTE 3: Financial Instruments Our financial instruments consist of cash and cash equivalents, investments in marketable securities, accounts receivable, accounts payable, debt and derivative instruments. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value. HEP's outstanding credit agreement borrowings also approximate fair value as interest rates are reset frequently at current interest rates. Fair value measurements are derived using inputs (assumptions that market participants would use in pricing an asset or liability, including assumptions about risk). GAAP categorizes inputs used in fair value measurements into three broad levels as follows: • • • (Level 1) Quoted prices in active markets for identical assets or liabilities. (Level 2) Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, similar assets and liabilities in markets that are not active or can be corroborated by observable market data. (Level 3) Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes valuation techniques that involve significant unobservable inputs. The carrying amounts and estimated fair values of our investments in marketable securities, derivative instruments and senior notes at December 31, 2014 and December 31, 2013 were as follows: Financial Instrument December 31, 2014 Assets: Marketable securities NYMEX futures contracts Commodity price swaps HEP interest rate swaps Total assets Liabilities: Commodity price swaps HollyFrontier senior notes HEP senior notes HEP interest rate swaps Total liabilities Carrying Amount Fair Value Level 1 Level 2 Level 3 Fair Value by Input Level (In thousands) $ $ $ $ 474,110 17,619 208,296 1,019 701,044 196,897 154,144 296,579 1,065 648,685 $ $ $ $ 474,110 17,619 208,296 1,019 701,044 196,897 155,250 291,000 1,065 644,212 $ $ $ $ — $ 17,619 — — 17,619 $ — $ — — — — $ 474,110 — 208,296 1,019 683,425 196,897 155,250 291,000 1,065 644,212 $ $ $ $ — — — — — — — — — — 65 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued Financial Instrument December 31, 2013 Assets: Marketable securities Commodity price swaps HEP interest rate swaps Total assets Liabilities: NYMEX futures contracts Commodity price swaps HollyFrontier senior notes HEP senior notes HEP interest rate swaps Total liabilities Carrying Amount Fair Value Fair Value by Input Level Level 1 (In thousands) Level 2 Level 3 $ $ $ $ 725,160 43,284 1,670 770,114 3,569 83,349 155,054 444,630 1,814 688,416 $ $ $ $ 725,160 43,284 1,670 770,114 3,569 83,349 161,250 471,750 1,814 721,732 $ $ $ $ — $ — — — $ 725,160 36,312 1,670 763,142 $ $ 3,569 — — — — 3,569 $ $ — $ 41,059 161,250 471,750 1,814 675,873 $ — 6,972 — 6,972 — 42,290 — — — 42,290 Level 1 Financial Instruments Our NYMEX futures contracts are exchange traded and are measured and recorded at fair value using quoted market prices, a Level 1 input. Level 2 Financial Instruments Investments in marketable securities and derivative instruments consisting of commodity price swaps and HEP's interest rate swaps are measured and recorded at fair value using Level 2 inputs. The fair values of the commodity price and interest rate swap contracts are based on the net present value of expected future cash flows related to both variable and fixed rate legs of the respective swap agreements. The measurements are computed using market-based observable inputs, quoted forward commodity prices with respect to our commodity price swaps and the forward London Interbank Offered Rate (“LIBOR”) yield curve with respect to HEP's interest rate swaps. The fair value of the marketable securities and senior notes is based on values provided by a third party, which were derived using market quotes for similar type instruments, a Level 2 input. 66 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued Level 3 Financial Instruments We have commodity price swap contracts that relate to forecasted sales of diesel and forecasted purchases of WCS and WTS for which quoted forward market prices were previously not readily available. The forward rate used to value these price swaps were derived using a projected forward rate using quoted market rates for similar products, adjusted for regional pricing and grade differentials, a Level 3 input. Effective December 31, 2014, we recategorized these swap contracts to Level 2 financial instruments due to increased visibility of quoted forward pricing information. Our policy is to recognize transfers in and out of Level 3 based on the fair value of the underlying financial instruments as of the end of the reporting period during which such transfers are made. The following table presents the changes in fair value of our Level 3 assets and liabilities (all related to derivative instruments) for the years ended December 31, 2014 and 2013: Level 3 Financial Instruments Liability balance at beginning of period Change in fair value: Recognized in other comprehensive income Recognized in cost of products sold Settlement date fair value of contractual maturities: Recognized in sales and other revenues Recognized in cost of products sold Transfer out of Level 3 Liability balance at end of period NOTE 4: Earnings Per Share Years Ended December 31, 2014 2013 (In thousands) $ (35,318) $ (33,658) 304,275 14,876 (88,326) (21,848) (173,659) $ — $ (71,751) 35,236 20,060 14,795 — (35,318) Basic earnings per share is calculated as net income attributable to HollyFrontier stockholders divided by the average number of shares of common stock outstanding.

The compensation cost charged against income for these plans was $26.1 million, $32.2 million and $36.3 million for the years ended December 31, 2014, 2013 and 2012, respectively. Our accounting policy for the recognition of compensation expense for awards with pro-rata vesting is to expense the costs ratably over the vesting periods. Additionally, HEP maintains a share-based compensation plan for Holly Logistic Services, L.L.C.'s non-employee directors and certain executives and employees. Compensation cost attributable to HEP’s share-based compensation plan was $3.5 million, $3.6 million and $2.7 million for the years ended December 31, 2014, 2013 and 2012, respectively. Restricted Stock and Restricted Stock Units Under our Long-Term Incentive Compensation Plan, we grant certain officers and other key employees restricted stock and restricted stock unit awards with awards generally vesting over a period of one to three years. Restricted stock award recipients are generally entitled to all the rights of absolute ownership of the restricted shares from the date of grant including the right to vote the shares and to receive dividends. Upon vesting, restrictions on the restricted shares lapse at which time they convert to common shares. In addition, we grant non-employee directors restricted stock unit awards, which typically vest over a period of one year and are payable in stock. The fair value of each restricted stock and restricted stock unit award is measured based on the grant date market price of our common shares and is amortized over the respective vesting period. A summary of restricted stock and restricted stock unit activity and changes during the year ended December 31, 2014 is presented below: Restricted Stock and Restricted Stock Units Grants Weighted Average Grant Date Fair Value Aggregate Intrinsic Value ($000) Outstanding at January 1, 2014 (non-vested) Granted Vesting (transfer / conversion to common stock) Forfeited Outstanding at December 31, 2014 (non-vested) 737,562 464,189 (452,711) (79,263) 669,777 $ $ 39.54 42.03 40.21 42.29 40.49 $ 24,180 For the years ended December 31, 2014, 2013 and 2012, restricted stock and restricted stock units vested having a grant date fair value of $18.2 million, $16.2 million and $27.7 million, respectively. For the years ended December 31, 2013 and 2012, we granted restricted stock and restricted stock units having a weighted average grant date fair value of $42.00 and $37.27, respectively. As of December 31, 2014, there was $20.8 million of total unrecognized compensation cost related to non-vested restricted stock and restricted stock unit grants. That cost is expected to be recognized over a weighted-average period of 1.6 years. Performance Share Units Under our Long-Term Incentive Compensation Plan, we grant certain officers and other key employees performance share units, which are payable in stock upon meeting certain criteria over the service period, and generally vest over a period of three years. Under the terms of our performance share unit grants, awards are subject to “financial performance” and “market performance” criteria. Financial performance is based on our financial performance compared to a peer group of independent refining companies, while market performance is based on the relative standing of total shareholder return achieved by HollyFrontier compared to peer group companies. The number of shares ultimately issued under these awards can range from zero to 200%. As of December 31, 2014, estimated share payouts for outstanding non-vested performance share unit awards averaged approximately 65%. 68 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued A summary of performance share unit activity and changes during the year ended December 31, 2014 is presented below: Performance Share Units Outstanding at January 1, 2014 (non-vested) Granted Vesting and transfer of ownership to recipients Forfeited Outstanding at December 31, 2014 (non-vested) Grants 983,610 283,769 (425,170) (117,155) 725,054 For the year ended December 31, 2014, we issued 416,111 shares of our common stock, representing a 98% payout on vested performance share units having a grant date fair value of $14.3 million. For the years ended December 31, 2013 and 2012, we issued common stock upon the vesting of the performance share units having a grant date fair value of $11.6 million and $6.0 million, respectively. As of December 31, 2014, there was $20.2 million of total unrecognized compensation cost related to non- vested performance share units having a grant date fair value of $43.70 per unit. That cost is expected to be recognized over a weighted-average period of 2.0 years. NOTE 6: Cash and Cash Equivalents and Investments in Marketable Securities Our investment portfolio at December 31, 2014 consisted of cash, cash equivalents and investments in marketable securities. We currently invest in marketable debt securities with the maximum maturity or put date of any individual issue generally not greater than one year from the date of purchase, which are usually held until maturity. All of these instruments are classified as available-for-sale. As a result, they are reported at fair value using quoted market prices. Interest income is recorded as earned. Unrealized gains and losses, net of related income taxes, are reported as a component of accumulated other comprehensive income. Upon sale or maturity, realized gains on our marketable debt securities are recognized as interest income. These gains are computed based on the specific identification of the underlying cost of the securities, net of unrealized gains and losses previously reported in other comprehensive income. Unrealized gains and losses on our available-for-sale securities are due to changes in market prices and are considered temporary. The following is a summary of our marketable securities: December 31, 2014 Certificates of deposit Commercial paper Corporate debt securities State and political subdivisions debt securities Total marketable securities December 31, 2013 Certificates of deposit Commercial paper Corporate debt securities State and political subdivisions debt securities Total marketable securities Amortized Cost Gross Unrealized Gain Gross Unrealized Loss Fair Value (Net Carrying Amount) (In thousands) $ $ $ $ 54,000 52,297 136,181 231,819 474,297 74,802 78,216 96,889 475,235 725,142 $ $ $ $ 10 7 1 5 23 21 28 6 49 104 $ $ $ $ — $ (4) (94) (112) (210) $ (1) $ — (44) (41) (86) $ 54,010 52,300 136,088 231,712 474,110 74,822 78,244 96,851 475,243 725,160 Interest income recognized on our marketable securities was $2.2 million and $2.1 million for the years ended December 31, 2014 and 2013, respectively. 69 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued NOTE 7: Inventories Inventory consists of the following components: Crude oil Other raw materials and unfinished products(1) Finished products(2) Lower of cost or market reserve Process chemicals(3) Repairs and maintenance supplies and other Total inventory December 31, 2014 2013 (In thousands) $ 581,592 $ 204,467 531,523 (397,478) 4,028 110,999 567,281 154,534 519,633 — 3,504 109,295 $ 1,035,131 $ 1,354,247 (1) Other raw materials and unfinished products include feedstocks and blendstocks, other than crude. (2) Finished products include gasolines, jet fuels, diesels, lubricants, asphalts, LPG’s and residual fuels. (3) Process chemicals include additives and other chemicals. Crude oil, other raw materials, unfinished products and finished products are carried at the lower of cost or market. Cost is determined principally under the LIFO valuation method to reflect a better matching of cost and revenue. Ending inventory costs in excess of market values are written down to current replacement costs and charged to cost of products sold in the period recorded. In subsequent periods a new lower of cost or market reserve determination is made based on current conditions. We determine the need for a lower of cost or market inventory adjustment by evaluating inventories on an aggregate basis. At December 31, 2014, market values had fallen below historical LIFO inventory costs and, as a result, we recognized a non-cash pretax loss of $397.5 million. Such losses are subject to reversal in subsequent periods, not to exceed historical LIFO costs, if prices recover. At December 31, 2014, the LIFO value of inventory, net of the lower of cost or market reserve, was equal to current costs. The excess of current cost over the LIFO value of inventory was $273.0 million at December 31, 2013. For the year ended December 31, 2012, we recognized a reduction of $4.2 million to cost of products sold due to the liquidation of certain quantities of LIFO inventory that were carried at historical acquisition costs below market value at the time of liquidation. NOTE 8: Properties, Plants and Equipment The components of properties, plants and equipment are as follows: December 31, 2014 2013 (In thousands) Land, buildings and improvements $ 255,260 $ Refining facilities Pipelines and terminals Transportation vehicles Other fixed assets Construction in progress Accumulated depreciation 2,634,432 1,226,923 35,178 136,545 564,103 4,852,441 (1,181,902) 3,670,539 $ $ 70 235,625 2,510,750 1,158,288 41,066 116,801 281,327 4,343,857 (949,261) 3,394,596 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued We capitalized interest attributable to construction projects of $11.8 million, $12.1 million and $9.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. Depreciation expense was $261.8 million, $213.6 million and $182.9 million for the years ended December 31, 2014, 2013 and 2012, respectively. For the years ended December 31, 2014, 2013 and 2012, depreciation expense included $58.1 million, $62.3 million and $55.5 million, respectively, attributable to HEP operations. NOTE 9: Goodwill We performed our annual goodwill impairment testing as of July 1, 2014, which entailed an assessment of our reporting unit fair values relative to their respective carrying values that were derived using a combination of both income and market approaches. Our income approach utilizes the discounted future expected cash flows and has an 80% weighting. Our market approach, which includes both the guideline public company and guideline transaction methods, each having a 10% weighting, utilizes pricing multiples derived from historical market transactions of similar assets. Our discounted cash flows reflect estimates of future cash flows based on both historical and forward crack-spreads, forecasted production levels, operating costs and capital expenditures. Based on our testing as of July 1, 2014, the fair value of our Cheyenne reporting unit exceeded its carrying cost by slightly less than 20%, and the fair value of our El Dorado and HEP reporting units exceeded their respective carrying values by a much larger percentage. Historically, the refining industry has experienced significant fluctuations in operating results over an extended business cycle including changes in prices of crude oil and refined products, changes in operating costs including natural gas and higher costs of complying with government regulations. It is reasonably possible that at some future downturn in refining operations that the goodwill related to our Cheyenne Refinery will be determined to be impaired. The following table provides a summary of changes to our goodwill balance by segment for the year ended December 31, 2014. Balance at January 1, 2014 Adjustment to goodwill Balance at December 31, 2014 Refining Segment HEP (In thousands) Total $ $ 2,042,931 (141) 2,042,790 $ $ 288,991 — 288,991 $ $ 2,331,922 (141) 2,331,781 During 2014, we recorded an insignificant reduction to goodwill due to the sale of certain business assets. NOTE 10: Environmental We expensed $28.5 million, $13.2 million and $46.1 million for the years ended December 31, 2014, 2013 and 2012, respectively, for environmental remediation obligations. In 2012, we increased certain environmental cost accruals to reflect revisions to certain cost estimates and the time frame for which certain environmental remediation and monitoring activities are expected to occur. The accrued environmental liability reflected in our consolidated balance sheets was $104.5 million and $87.8 million at December 31, 2014 and 2013, respectively, of which $81.8 million and $73.6 million, respectively, were classified as other long- term liabilities. These accruals include remediation and monitoring costs expected to be incurred over an extended period of time (up to 30 years for certain projects). 71 Table of Contents NOTE 11: Debt HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued HollyFrontier Credit Agreement On July 1, 2014, we entered into a new $1 billion senior unsecured revolving credit facility maturing in July 2019 (the “HollyFrontier Credit Agreement”) and contemporaneously terminated our previous $1 billion senior secured revolving credit agreement. The HollyFrontier Credit Agreement may be used for revolving credit loans and letters of credit from time to time and is available to fund general corporate purposes. Indebtedness under the HollyFrontier Credit Agreement is recourse to HollyFrontier and guaranteed by certain of our wholly-owned subsidiaries. At December 31, 2014, we were in compliance with all covenants, had no outstanding borrowings and had outstanding letters of credit totaling $4.7 million under the HollyFrontier Credit Agreement. HEP Credit Agreement HEP has a $650 million senior secured revolving credit facility that matures in November 2018 (the “HEP Credit Agreement”) and is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. It is also available to fund letters of credit up to a $50 million sub-limit. At December 31, 2014, HEP was in compliance with all of its covenants, had outstanding borrowings of $571.0 million and no outstanding letters of credit under the HEP Credit Agreement. Indebtedness under the HEP Credit Agreement bears interest, at HEP's option, at either a reference rate announced by the administrative agent plus an applicable margin or at a rate equal to LIBOR plus an applicable margin. In each case, the applicable margin is based upon the ratio of HEP’s funded debt to earnings before interest, taxes, depreciation and amortization (as defined in the HEP Credit Agreement). The weighted average interest rates in effect on HEP’s Credit Agreement borrowings were 2.152% and 2.163% at December 31, 2014 and 2013, respectively. HEP’s obligations under the HEP Credit Agreement are collateralized by substantially all of HEP’s assets. Indebtedness under the HEP Credit Agreement involves recourse to HEP Logistics Holdings, L.P., its general partner, and is guaranteed by HEP’s wholly- owned subsidiaries. Any recourse to the general partner would be limited to the extent of HEP Logistics Holdings, L.P.’s assets, which other than its investment in HEP, are not significant. HEP’s creditors have no recourse to our other assets. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries. HollyFrontier Senior Notes Our 6.875% senior notes ($150 million aggregate principal amount maturing November 2018) (the “HollyFrontier Senior Notes”) are unsecured and impose certain restrictive covenants, including limitations on our ability to incur additional debt, incur liens, enter into sale-and-leaseback transactions, pay dividends, enter into mergers, sell assets and enter into certain transactions with affiliates. Additionally, we have certain redemption rights under the HollyFrontier Senior Notes. At any time, following notice to the trustee, that the HollyFrontier Senior Notes are rated investment grade by both Moody's and Standard & Poor's and no default or event of default exists, we are not subject to many of the foregoing covenants (a "Covenant Suspension"). As of December 31, 2014, the HollyFrontier Senior Notes were rated investment grade by both Standard & Poor's (BBB-) and Moody's (Baa3). As a result, we are under the Covenant Suspension pursuant to the terms of the indenture governing the HollyFrontier Senior Notes. In June 2013, we redeemed our $286.8 million aggregate principal amount of 9.875% senior notes maturing June 2017 at a redemption cost of $301.0 million, at which time we recognized a $22.1 million early extinguishment loss consisting of a $14.2 million debt redemption premium and an unamortized discount of $7.9 million. In September 2012, we redeemed our $200 million aggregate principal amount of 8.5% senior notes maturing September 2016 at a redemption price of $208.5 million. HollyFrontier Financing Obligation We have a financing obligation that relates to a sale and lease-back of certain crude oil tankage that we sold to an affiliate of Plains All American Pipeline, L.P. (“Plains”) in October 2009 for $40.0 million. Monthly lease payments are recorded as a reduction in principal over the 15-year lease term ending in 2024. 72 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued HEP Senior Notes In March 2012, HEP issued $300 million in an aggregate principal amount of 6.5% HEP senior notes maturing March 2020 (the “HEP Senior Notes”). The $294.8 million in net proceeds were used to repay $157.8 million aggregate principal amount of 6.25% HEP senior notes, $72.9 million in promissory notes due to HollyFrontier, related fees, expenses and accrued interest in connection with these transactions and to repay borrowings under the HEP Credit Agreement. In April 2012, HEP called for redemption the remaining $27.2 million aggregate principal amount outstanding of 6.25% HEP senior notes. The HEP Senior Notes are unsecured and impose certain restrictive covenants, including limitations on HEP’s ability to incur additional indebtedness, make investments, sell assets, incur certain liens, pay distributions, enter into transactions with affiliates, and enter into mergers. At any time when the HEP Senior Notes are rated investment grade by both Moody’s and Standard & Poor’s and no default or event of default exists, HEP will not be subject to many of the foregoing covenants. Additionally, HEP has certain redemption rights under the HEP Senior Notes. In March 2014, HEP redeemed its $150.0 million aggregate principal amount of 8.25% senior notes maturing March 2018 at a redemption cost of $156.2 million, at which time HEP recognized a $7.7 million early extinguishment loss consisting of a $6.2 million debt redemption premium and unamortized discount and financing cost of $1.5 million. HEP funded the redemption with borrowings under the HEP Credit Agreement. Indebtedness under the HEP Senior Notes involves recourse to HEP Logistics Holdings, L.P., its general partner, and is guaranteed by HEP’s wholly-owned subsidiaries. However, any recourse to the general partner would be limited to the extent of HEP Logistics Holdings, L.P.’s assets, which other than its investment in HEP, are not significant. HEP’s creditors have no recourse to our other assets. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries.

We are exposed to market risks related to the volatility in crude oil and refined products, as well as volatility in the price of natural gas used in our refining operations. We periodically enter into derivative contracts in the form of commodity price swaps and futures contracts to mitigate price exposure with respect to: • • • • • our inventory positions; natural gas purchases; costs of crude oil and related grade differentials; prices of refined products; and our refining margins. Accounting Hedges We have swap contracts serving as cash flow hedges against price risk on forecasted purchases of natural gas and WTI crude oil and forecasted sales of refined product. These contracts have been designated as accounting hedges and are measured at fair value with offsetting adjustments (gains/losses) recorded directly to other comprehensive income. These fair value adjustments are later reclassified to earnings as the hedging instruments mature. On a quarterly basis, hedge ineffectiveness is measured by comparing the change in fair value of the swap contracts against the expected future cash inflows/outflows on the respective transaction being hedged. Any hedge ineffectiveness is also recognized in earnings. 74 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued The following table presents the pre-tax effect on other comprehensive income (“OCI”) and earnings due to fair value adjustments and maturities of commodity price swaps under hedge accounting: Unrealized Gain (Loss) Recognized in OCI Gain (Loss) Recognized in Earnings Due to Settlements Amount Location Gain (Loss) Attributable to Hedge Ineffectiveness Recognized in Earnings Location Amount Year Ended December 31, 2014 Commodity price swaps Change in fair value Gain reclassified to earnings due to settlements Amortization of discontinued hedges reclassified to earnings Total Year Ended December 31, 2013 Commodity price swaps Change in fair value Gain reclassified to earnings due to settlements Amortization of discontinued hedges reclassified to earnings Total Year Ended December 31, 2012 Commodity price swaps Change in fair value Loss reclassified to earnings due to settlements Total $ $ $ $ $ $ Sales and other revenues Cost of products sold Operating expenses Sales and other revenues Cost of products sold Operating expenses 107,518 (52,884) 1,080 55,714 (8,808) (16,410) 900 (24,318) Sales and other revenues Operating expenses (248,399) 55,175 (193,224) $ $ $ $ $ $ (In thousands) Sales and other revenues Cost of products sold Operating expenses Sales and other revenues Cost of products sold Sales and other revenues Cost of products sold 88,326 (37,313) 791 51,804 (20,060) 38,949 (3,379) 15,510 (98,750) 43,575 (55,175) $ $ $ $ $ $ 274 (4,377) (547) (4,650) 45 515 560 (491) (515) (1,006) As of December 31, 2014, we have the following notional contract volumes related to outstanding derivative instruments serving as cash flow hedges against price risk on forecasted purchases of natural gas and crude oil and sales of refined products: Derivative instruments Natural gas - long WTI crude oil - long Ultra-low sulfur diesel - short Notional Contract Volumes by Year of Maturity Total Outstanding Notional 2015 2016 2017 Unit of Measure 28,800,000 9,600,000 9,600,000 9,600,000 MMBTU 4,380,000 4,380,000 4,380,000 4,380,000 — — — Barrels — Barrels In 2013, we dedesignated certain commodity price swaps (long positions) that previously received hedge accounting treatment. These contracts now serve as economic hedges against price risk on forecasted natural gas purchases totaling 28,800,000 MMBTU's to be purchased ratably through 2017. As of December 31, 2014, we have an unrealized loss of $3.2 million classified in accumulated other comprehensive income that relates to the application of hedge accounting prior to dedesignation that is amortized as a charge to operating expenses as the contracts mature. Economic Hedges We also have swap contracts that serve as economic hedges (derivatives used for risk management, but not designated as accounting hedges) to fix our purchase price on forecasted purchases of WTI crude oil, and to lock in the spread between WTI and WCS and WTS on forecasted purchases of crude oil inventory. Also, we have NYMEX futures contracts to lock in prices on forecasted purchases of inventory. These contracts are measured at fair value with offsetting adjustments (gains/losses) recorded directly to income. 75 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued The following table presents the pre-tax effect on income due to maturities and fair value adjustments of our economic hedges: Location of Gain (Loss) Recognized in Income 2014 Years Ended December 31, 2013 (In thousands) 2012 Cost of products sold Operating expenses Total $ $ 68,509 (185) 68,324 $ $ 20,751 (5,250) 15,501 $ $ 12,295 573 12,868 As of December 31, 2014, we have the following notional contract volumes related to our outstanding derivative contracts serving as economic hedges: Derivative Instrument Notional Contract Volumes by Year of Maturity Total Outstanding Notional 2015 2016 2017 Unit of Measure Commodity price swap (WTI basis spread) - long 4,015,000 4,015,000 Commodity price swap (WTI) - long 1,095,000 1,095,000 — — — Barrels — Barrels Commodity price swap (natural gas) - long 28,800,000 9,600,000 9,600,000 9,600,000 MMBTU Commodity price swap (natural gas) - short 28,800,000 9,600,000 9,600,000 9,600,000 MMBTU NYMEX futures (WTI) - short 2,058,000 2,058,000 — — Barrels Interest Rate Risk Management HEP uses interest rate swaps to manage its exposure to interest rate risk. As of December 31, 2014, HEP had three interest rate swap contracts that hedge its exposure to the cash flow risk caused by the effects of LIBOR changes on $305.0 million in credit agreement advances. The first interest rate swap effectively converts $155.0 million of LIBOR based debt to fixed rate debt having an interest rate of 0.99% plus an applicable margin of 2.00% as of December 31, 2014, which equaled an effective interest rate of 2.99%. This swap matures in February 2016. HEP has two additional interest rate swaps with identical terms which effectively convert $150.0 million of LIBOR based debt to fixed rate debt having an interest rate of 0.74% plus an applicable margin of 2.00% as of December 31, 2014, which equaled an effective interest rate of 2.74%. Both of these swap contracts mature in July 2017. All of these swap contracts have been designated as cash flow hedges. To date, there has been no ineffectiveness on these cash flow hedges. 76 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued The following table presents the pre-tax effect on other comprehensive income and earnings due to fair value adjustments and maturities of HEP's interest rate swaps under hedge accounting: Year Ended December 31, 2014 Interest rate swaps Change in fair value Loss reclassified to earnings due to settlements Total Year Ended December 31, 2013 Interest rate swaps Change in fair value Loss reclassified to earnings due to settlements Amortization of discontinued hedge reclassified to earnings Total Year Ended December 31, 2012 Interest rate swaps Change in fair value Loss reclassified to earnings due to settlements Amortization of discontinued hedge reclassified to earnings Total Unrealized Gain (Loss) Recognized in OCI Loss Recognized in Earnings Due to Settlements Location (In thousands) Amount $ $ $ $ $ $ (2,104) 2,202 98 1,194 2,092 849 4,135 (4,418) 1,508 5,095 2,185 Interest expense Interest expense Interest expense $ $ $ $ $ $ (2,202) (2,202) (2,941) (2,941) (6,603) (6,603) The following table presents the fair value and balance sheet locations of our outstanding derivative instruments.

In September 2014, our Board of Directors approved a $500 million share repurchase program authorizing us to repurchase common stock in the open market or through privately negotiated transactions. As of December 31, 2014, we had remaining authorization to repurchase up to $444.4 million under this stock repurchase program. In February 2015, our Board of Directors approved a $500 million share repurchase program, which replaced all existing share repurchase programs including approximately $425.0 million remaining under the existing $500 million share repurchase program. The timing and amount of stock repurchases will depend on market conditions, corporate, regulatory and other relevant considerations. This program may be discontinued at any time by our Board of Directors. In addition, we are authorized by our Board of Directors to repurchase shares in an amount sufficient to offset shares issued under our compensation programs. In May 2012, we entered into a structured share repurchase arrangement with a financial institution under which we provided an up-front cash payment of $100.0 million and, depending on market conditions, would either receive shares of our common stock or cash at the expiration of the agreement. The agreement expired in September 2012 at which time we received our up-front payment plus an additional $8.6 million in cash that was recorded as additional capital. During the years ended December 31, 2014, 2013 and 2012, we withheld shares of our common stock from certain employees in the amounts of $11.4 million, $11.3 million and $22.4 million, respectively. These withholdings were made under the terms of restricted stock and performance share unit agreements upon vesting, at which time, we concurrently made cash payments to fund payroll and income taxes on behalf of officers and employees who elected to have shares withheld from vested amounts to pay such taxes. 81 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued NOTE 15: Other Comprehensive Income (Loss) The components and allocated tax effects of other comprehensive income (loss) are as follows: Year Ended December 31, 2014 Net unrealized loss on marketable securities Net unrealized gain on hedging instruments Net change in pension and other post-retirement benefit obligations Other comprehensive income Less other comprehensive income attributable to noncontrolling interest Other comprehensive income attributable to HollyFrontier stockholders Year Ended December 31, 2013 Net unrealized gain on marketable securities Net unrealized loss on hedging instruments Net change in pension and other post-retirement benefit obligations Other comprehensive income Less other comprehensive income attributable to noncontrolling interest Other comprehensive income attributable to HollyFrontier stockholders Year Ended December 31, 2012 Net unrealized loss on marketable securities Net unrealized loss on hedging instruments Net change in pension and other post-retirement benefit obligations Other comprehensive loss Less other comprehensive income attributable to noncontrolling interest Other comprehensive loss attributable to HollyFrontier stockholders Before-Tax Tax Expense (Benefit) (In thousands) After-Tax $ $ $ $ $ $ (157) $ (62) $ 55,812 (11,425) 44,230 60 44,170 34 (20,183) 37,593 17,444 2,315 15,129 $ $ $ (236) $ (191,039) 51,391 (139,884) 1,364 (141,248) $ 21,583 (4,423) 17,098 — 17,098 17 (8,669) 14,534 5,882 — 5,882 $ $ $ (95) $ (74,846) 19,991 (54,950) — (54,950) $ (95) 34,229 (7,002) 27,132 60 27,072 17 (11,514) 23,059 11,562 2,315 9,247 (141) (116,193) 31,400 (84,934) 1,364 (86,298) 82 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued The following table presents the income statement line item effects for reclassifications out of accumulated other comprehensive income (“AOCI”): AOCI Component Gain (Loss) Reclassified From AOCI Income Statement Line Item Marketable securities $ Years Ended December 31, 2012 $ 2014 2013 (In thousands) 39 $ — 39 15 24 4 — 4 2 2 Interest income 59 326 Gain on sale of marketable equity securities 385 150 235 Net of tax Income tax expense Hedging instruments: Commodity price swaps Interest rate swaps Pension and other post-retirement benefit obligations: Pension obligation Post-retirement healthcare obligation Retirement restoration plan 88,326 (37,313) 791 (2,202) 49,602 19,712 29,890 1,335 31,225 — — — — — — 482 3,366 448 4,296 1,663 2,633 (920) (356) (564) (20,060) 38,949 (3,379) (2,941) 12,569 5,554 7,015 1,783 8,798 (3,226) (30,127) (4,236) (37,589) (14,547) (23,042) 646 2,868 526 4,040 1,563 2,477 (111) (43) (68) (98,750) Sales and other revenues 43,575 Cost of products sold — Operating expenses Interest expense (6,603) (61,778) (22,590) (39,188) Net of tax Income tax expense (benefit) 3,753 Noncontrolling interest (35,435) Net of tax and noncontrolling interest (226) Cost of products sold (1,486) Operating expenses (244) General and administrative expenses (1,956) (761) Income tax benefit (1,195) Net of tax — Cost of products sold 1,913 Operating expenses 39 General and administrative expenses 1,952 759 Income tax expense 1,193 Net of tax (63) General and administrative expenses (25) (38) Net of tax Income tax benefit Total reclassifications for the period $ 33,296 $ (11,811) $ (35,240) Accumulated other comprehensive income in the equity section of our consolidated balance sheets includes: December 31, 2014 2013 Unrealized gain on post-retirement benefit obligations Unrealized gain (loss) on marketable securities Unrealized gain (loss) on hedging instruments, net of noncontrolling interest Accumulated other comprehensive income $ $ 83 $ (In thousands) 20,689 (85) 7,290 27,894 $ 27,691 10 (26,879) 822 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued NOTE 16: Retirement Plans Post-retirement Healthcare Plans We provide post-retirement medical benefits to certain eligible employees.

In June 2013, we made contributions of $22.7 million to the Plan, which was sufficient for the Plan to settle its obligations to all participants including the premium paid to the non-participating annuity provider. In 2013, we recognized a pre-tax pension settlement charge of $39.5 million, of which $37.6 million was reclassified out of accumulated other comprehensive income, representing the irrevocable portion of our obligation. Net periodic pension expense was $42.6 million and $6.6 million for the years ended December 31, 2013 and 2012, respectively. The following table sets forth the changes in the benefit obligation and plan assets of our retirement plan for the year ended December 31, 2013: 85 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued Change in plan's benefit obligation Pension plan's benefit obligation - beginning of year Interest cost Benefits paid Actuarial loss Settlements paid Pension plan's benefit obligation - end of year Change in pension plan assets Fair value of plan assets - beginning of year Actual return on plan assets Benefits paid Employer contributions Settlements paid Fair value of plan assets - end of year Year Ended December 31, 2013 (In thousands) $ $ $ $ 95,485 1,797 (3,957) 2,981 (96,306) — 77,757 (219) (3,957) 22,725 (96,306) — Additionally, we had a program that provided transition benefit payments to certain employees that participated in a previously terminated defined benefit plan. The program extended through 2014 and provided payments subsequent to year-end provided the employee was employed by us on the last day of each year. The payments are based on each employee's years of service and eligible salary. Transition benefit costs under this program were $10.8 million, $12.5 million and $15.6 million for the years ended December 31, 2014, 2013 and 2012, respectively. Retirement Restoration Plan We have an unfunded retirement restoration plan that provides for additional payments from us so that total retirement plan benefits for certain executives will be maintained at the levels provided in the retirement plan before the application of Internal Revenue Code limitations. We expensed $1.2 million, $0.4 million and $0.3 million for the years ended December 31, 2014, 2013 and 2012, respectively, in connection with this plan. The accrued liability reflected in the consolidated balance sheets was $3.0 million and $6.8 million at December 31, 2014 and 2013, respectively. As of December 31, 2014, the projected benefit obligation under this plan was $3.0 million. Annual benefit payments of $0.2 million are expected to be paid through 2024, which reflect expected future service. Defined Contribution Plans We have a defined contribution “401(k)” plan that covers substantially all employees. Our contributions are based on an employee's eligible compensation and years of service. We also partially match the employee's contributions. We expensed $16.1 million, $15.5 million and $16.0 million for the years ended December 31, 2014, 2013 and 2012, respectively, in connection with these plans. 86 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued NOTE 17: Lease Commitments We lease certain office and storage facilities, rail cars and other equipment under long-term operating leases, most of which contain renewal options. At December 31, 2014, the minimum future rental commitments under operating leases having non-cancellable lease terms in excess of one year are as follows: 2015 2016 2017 2018 2019 Thereafter Total (In thousands) 29,501 27,893 19,370 12,262 8,288 8,485 105,799 $ $ Rental expense charged to operations was $58.9 million, $48.5 million and $42.6 million for the years ended December 31, 2014, 2013 and 2012, respectively. For the years ended December 31, 2014, 2013 and 2012, rental expense included $8.0 million, $8.3 million and $8.1 million, respectively, in costs attributable to the HEP operations. NOTE 18: Contingencies and Contractual Commitments We are a party to various litigation and legal proceedings which we believe, based on advice of counsel, will not either individually or in the aggregate have a materially adverse effect on our financial condition, results of operations or cash flows. In early February 2015, we received communications from the United Steelworkers Union representing employees at our El Dorado and Woods Cross Refineries of its intention to commence a work stoppage in early May 2015 and could receive a similar communication from the United Steelworkers Union representing employees at our Cheyenne Refinery. We have plans allowing for the continued operations of all three refineries in the event the union does commence a work stoppage and believe such plans are adequate to allow continued operations of all three refineries. Pursuant to the 2007 Energy Independence and Security Act, the Environmental Protection Agency (“EPA”) promulgated the Renewable Fuel Standard 2 (“RFS2”) regulations reflecting the increased volume of renewable fuels mandated to be blended into the nation's fuel supply. The regulations, in part, require refiners to add annually increasing amounts of “renewable fuels” to their petroleum products or purchase credits, known as renewable identification numbers (“RINs”), in lieu of such blending. The EPA has not yet finalized the 2014 percentage standards under its RFS2 program. The estimated quantity of renewable fuels or RINs that we are required to purchase and that have been accrued for as of and for the year ended December 31, 2014 are based on quantities proposed by the EPA in November 2013. Contractual Commitments We have various long-term agreements (entered in the normal course of business) to purchase crude oil, natural gas, feedstocks and other resources to ensure we have adequate supplies to operate our refineries. The substantial majority of our purchase obligations are based on market prices or rates. These contracts expire in 2015 through 2025. We also have long-term agreements with third parties for the transportation and storage of crude oil, natural gas and feedstocks to our refineries and for terminal and storage services that expire in 2015 through 2033. At December 31, 2014, the minimum future transportation and storage fees under transportation agreements having terms in excess of one year are as follows: 87 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued 2015 2016 2017 2018 2019 Thereafter Total $ (In thousands) 157,931 129,928 118,504 101,166 92,920 586,271 $ 1,186,720 Transportation and storage costs incurred under these agreements totaled $164.6 million, $122.0 million and 89.4 million for the years ended December 31, 2014, 2013 and 2012, respectively. These amounts do not include contractual commitments under our long-term transportation agreements with HEP, as all transactions with HEP are eliminated in these consolidated financial statements. NOTE 19: Segment Information Our operations are organized into two reportable segments, Refining and HEP. Our operations that are not included in the Refining and HEP segments are included in Corporate and Other. Intersegment transactions are eliminated in our consolidated financial statements and are included in Consolidations and Eliminations. The Refining segment represents the operations of the El Dorado, Tulsa, Navajo, Cheyenne and Woods Cross Refineries and NK Asphalt (aggregated as a reportable segment). Refining activities involve the purchase and refining of crude oil and wholesale and branded marketing of refined products, such as gasoline, diesel fuel and jet fuel. These petroleum products are primarily marketed in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. Additionally, the Refining segment includes specialty lubricant products produced at our Tulsa Refineries that are marketed throughout North America and are distributed in Central and South America. NK Asphalt operates various asphalt terminals in Arizona, New Mexico and Oklahoma. The HEP segment includes all of the operations of HEP, which owns and operates logistics assets consisting of petroleum product and crude oil pipelines and terminal, tankage and loading rack facilities in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. The HEP segment also includes a 75% interest in UNEV (a consolidated subsidiary of HEP) and a 25% interest in the SLC Pipeline. Revenues from the HEP segment are earned through transactions with unaffiliated parties for pipeline transportation, rental and terminalling operations as well as revenues relating to pipeline transportation services provided for our refining operations. Due to certain basis differences, our reported amounts for the HEP segment may not agree to amounts reported in HEP’s periodic public filings. The accounting policies for our segments are the same as those described in the summary of significant accounting policies (see Note 1). 88 Table of Contents HOLLYFRONTIER CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Continued Year Ended December 31, 2014 Sales and other revenues Depreciation and amortization Income (loss) from operations Capital expenditures Total assets Year Ended December 31, 2013 Sales and other revenues Depreciation and amortization Income (loss) from operations Capital expenditures Total assets Year Ended December 31, 2012 Sales and other revenues Depreciation and amortization Income (loss) from operations Capital expenditures Total assets Refining HEP Corporate and Other Consolidations and Eliminations Consolidated Total $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ 19,706,225 293,871 491,106 465,472 6,965,245 $ 332,626 60,548 $ $ 156,453 $ 79,819 $1,434,572 20,105,443 233,182 1,237,687 344,113 7,094,558 $ 307,053 $ 64,701 $ 133,522 $ 51,856 $1,413,907 20,042,955 181,247 2,879,383 278,705 6,702,872 $ 288,501 $ 57,789 $ 133,723 44,929 $ $1,426,800 $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ (In thousands) 2,103 $ $ 9,790 (129,874) $ $ 19,530 $ 1,150,865 $ 1,314 $ 6,391 (123,030) $ $ 29,158 $ 1,881,121 $ 1,048 $ 4,660 (126,840) $ $ 11,629 $ 2,531,967 (276,627) $ (828) $ (2,151) $ — $ (320,042) $ 19,764,327 363,381 515,534 564,821 9,230,640 (253,250) $ (828) $ (2,105) $ — $ (332,847) $ 20,160,560 303,446 1,246,074 425,127 10,056,739 (241,780) $ (828) $ (2,120) $ — $ (332,642) $ 20,090,724 242,868 2,884,146 335,263 10,328,997 HEP segment revenues from external customers were $57.3 million, $53.4 million and $47.6 million for the years ended December 31, 2014, 2013 and 2012, respectively. NOTE 20: Supplemental Guarantor/Non-Guarantor Financial Information Our obligations under the HollyFrontier Senior Notes have been jointly and severally guaranteed by the substantial majority of our existing and future restricted subsidiaries (“Guarantor Restricted Subsidiaries”). These guarantees are full and unconditional. HEP, in which we have a 39% ownership interest at December 31, 2014, and its subsidiaries (collectively, “Non-Guarantor Non- Restricted Subsidiaries”), and certain of our other subsidiaries (“Non-Guarantor Restricted Subsidiaries”) have not guaranteed these obligations. The following condensed consolidating financial information is provided for HollyFrontier Corporation (the “Parent”), the Guarantor Restricted Subsidiaries, the Non-Guarantor Restricted Subsidiaries and the Non-Guarantor Non-Restricted Subsidiaries. The information has been presented as if the Parent accounted for its ownership in the Guarantor Restricted Subsidiaries, and the Guarantor Restricted Subsidiaries accounted for the ownership of the Non-Guarantor Restricted Subsidiaries and Non-Guarantor Non-Restricted Subsidiaries, using the equity method of accounting.
