SHAREHOLDERS

HollyFrontier had a momentous year in 2017. We completed the acquisition of Petro-Canada 
Lubricants Inc. (PCLI), which was a transformative step in helping us strengthen our earnings and 
deepen our product offerings. We also positioned our three business segments for value creation. 
We remained steadfast in our commitment to continuous improvement and safe and reliable  
operations. That is to say in 2017, we delivered an overall strong performance and advanced our 
efforts to provide exceptional returns for our shareholders, our employees and our communities.  

FINANCIAL RESULTS REFLECT INVESTMENTS AND   
OPERATIONAL IMPROVEMENTS

Our financial results for 2017 are a measure of the progress we  
have made as a company in recent years. They reflect reliability  
initiatives we set in motion and the disciplined investments we  
made to accelerate superior performance. A few highlights include: 

•  Generated operating cash flow of $951 million. 

•  Achieved net income attributable to HFC shareholders  

of $805 million.

Lubricants: The HollyFrontier Lubricants & Specialty Products  
segment (HF LSP) includes the operations of our Petro-Canada 
Lubricants business in addition to specialty lubricant products  
produced at our Tulsa Refinery.  With the addition of the Petro- 
Canada Lubricants business, we became the fourth largest lubricants 
producer in North America with a capacity of 28,000 barrels per day, 
which is approximately 10% of North American production. 

We produce all grades of high quality base oils that are used as the 
foundation in every finished lubricant and specialty product. In 2017, 
we were North America’s leading producer of Group III base oils. 

•  Realized refinery gross margins of $11.56 per produced barrel sold.

•  Ended the year with a strong balance sheet, including $631 million 

in cash and short-term investments and approximately $992 million 
in long-term debt, exclusive of Holly Energy Partners, L.P.  
(HEP) debt. 

We delivered on our commitment to return cash to shareholders 
through dividend payments totaling $235 million in 2017. We  
have returned more than $4.4 billion in payments to shareholders  
through dividends and share repurchases since the merger of  
Holly Corporation and Frontier Oil Corporation in 2011.

With a global footprint across 80 countries and more than  
350 varieties of world-class advanced lubricants, specialty fluids, 
greases and innovative products, including the Petro Canada  
Lubricants and Specialty Products brand, our HF LSP segment is 
primed for long-term expansion through strategic internal and  
external opportunities. 

Refining: We completed a number of projects and initiatives  
throughout the past few years designed to increase the operational 
capabilities, reliability and efficiency of our five U.S. refineries. In 
2017, we began to reap the benefits of these efforts: 

We also maintained our investment grade rating from S&P, Moody’s, 
and Fitch, underpinned by our strong balance sheet and excellent 
liquidity position. We are uniquely positioned to capitalize on growth 
opportunities, while continuing to invest in our businesses and return 
capital to our shareholders.

•  El Dorado completed a two-year initiative to optimize the  

configuration and utilization of a decade worth of investments, the 
last being our Naphtha Fractionation Project. This work enabled  
us to optimize the plant’s stream day capability to 160,000 barrels  
per day, up from 138,000 barrels per day.

SIGNIFICANT ADVANCEMENTS ACROSS   
OUR THREE BUSINESSES 

With the completion of the PCLI acquisition in early 2017, HollyFron-
tier continued to execute on our strategic intent to advance and grow 
each of our businesses – lubricants, refining, and midstream (through 
our holdings in HEP). Our 2017 highlights are:  

•  Tulsa continues to benefit from strategic investments, such as coker 
reliability and intermediate logistics, and continued optimization 
realized by running the two refinery sites as one facility. 

 In 2017, we also achieved a full-year’s value on our recently 
revamped fluid catalytic cracking (FCC) process.

H O L LY F R O N T I E R  CO R P O R AT I O N   2017 Annual Report

 
“ As we move forward through 2018, we  
will continue to be guided by our core values  
of safety, health, corporate citizenship,  
environmental stewardship and  
continuous improvement.”

•  Navajo completed a debottleneck project in early 2017, raising  
capability to 111,000 barrels per day while improving reliability.  
In addition, this project increased our refinery’s operational  
flexibility by enabling incremental high American Petroleum  
Institute (API) gravity crude processing and improving  
gasoline/diesel cut-point flexibility. 

 The debottleneck project was executed during the first quarter of 
2017 Navajo turnaround. We are proud of our team for completing 
this vast and complex undertaking, while remaining on budget and 
schedule. Also in 2017, Navajo completed and successfully started up 
our new FCC gasoline hydrotreater, enabling our refinery to produce 
Tier 3 gasoline.

•  Woods Cross continued to utilize the increased capacity created 
during its expansion project completed in 2016, running a record 
38,000 barrels per day in the fourth quarter of 2017. We also  
performed additional projects to substantially increase our  
diesel production.

•  Cheyenne efforts have been focused on increasing reliability,  
and we saw improved operations in 2017 versus prior years.  
This improvement, along with investments in a new hydrogen plant  
and asphalt rail loading facility, enabled higher crude rates and  
substantially more heavy crude processing capability. 

Our refining fleet is now capable of running between 450,000 and 
470,000 barrels per day on an annual average basis. We achieved  
two significant operating records in 2017 – a new best quarter in the 
second quarter of 467,000 barrels per day and a new annual record  
of 439,000 barrels per day. 

Holly Energy Partners: In 2017, we completed an incentive distribu-
tion rights (IDR) simplification transaction between HollyFrontier and 
HEP, pursuant to which HollyFrontier’s HEP incentive distribution 
rights were cancelled and our general partner interest in HEP was  
converted into a non-economic interest. In consideration, we received 

George J. Damiris  
Chief Executive Officer  
and President

37.25 million HEP units, which had a market value of approximately 
$1.9 billion at year-end 2017.  We believe this agreement provides 
more transparency on the valuation of HollyFrontier’s stake in HEP 
and will lower HEP’s cost of capital, facilitating growth. 

HollyFrontier expects to continue benefitting from HEP’s strong  
performance, stable cash flows and continued growth. HEP intends  
to leverage its existing footprint to grow organically, especially in the 
Permian Basin, and it will also continue its disciplined pursuit of  
value-enhancing acquisitions. We will also explore future dropdown 
opportunities based on HollyFrontier’s ability to acquire or build  
new assets.

DRIVING CONTINUED VALUE CREATION   
ACROSS OUR BUSINESSES IN 2018

As we move forward through 2018, HollyFrontier will continue to  
be guided by our core values of safety, health, corporate citizenship, 
environmental stewardship and continuous improvement. Our  
employees are fundamental to who we are and what we do, and we  
are grateful for their efforts. It is due to their hard work and dedication 
that we expect to continue delivering exceptional performance, while 
operating safely and reliably.

We believe HollyFrontier is ideally positioned to generate value to 
shareholders from our three strong businesses, which serve as our 
platform for growth and are supported by our strong balance  
sheet and financial position.  

We look forward to continued success in 2018 and in sharing it with 
you. On behalf of our board of directors and our employees, we thank 
you for your continued investment in HollyFrontier. 

Sincerely,

George Damiris  
Chief Executive Officer and President

REFINERY OPERATIONS 

Our refinery operations serve the Mid-Continent, Southwest and Rocky Mountain regions of the United States. We own and operate 
five complex refineries having a combined crude oil processing capacity of 457,000 barrels per stream day. Each of our refineries 
has the complexity to convert discounted, heavy and sour crude oils into a high percentage of gasoline, diesel and other high-value 
refined products.

The tables presented below and elsewhere in this discussion of our refinery operations set forth information, including non-GAAP 
performance measures, about our refinery operations. The cost of products and refinery gross and net operating margins do not 
include  the  non-cash  effects  of  lower  of  cost  or  market  inventory  valuation  adjustments  and  depreciation  and  amortization. 
Reconciliations to amounts reported under GAAP are provided under “Reconciliations to Amounts Reported Under Generally 
Accepted Accounting Principles” following Item 7A of Part II of this Form 10-K. 

During the fourth quarter of 2017, we revised the following refining segment operating data computations: refinery gross margin; 
net operating margin; and operating expenses to better align with  similar measurements provided by  other companies in our 
industry  and  to  facilitate  comparison  of  our  refining  performance  relative  to  our  peers.  Effective  with  this  change,  these 
measurements are now inclusive of all refining segment activities including HFC Asphalt operations and revenues and costs related 
to products purchased for resale and excess crude oil sales. All prior period data has been retrospectively adjusted to reflect our 
current presentation.

Footnote references are provided under our Consolidated Refinery Operating Data table on page 7.

The El Dorado Refinery is located on 1,100 acres south of El Dorado, Kansas and is a fully integrated refinery. The principal 
processing units at the El Dorado Refinery consist of crude and vacuum distillation; hydrodesulfurization of naphtha, kerosene, 
diesel, and gas oil streams; isomerization; catalytic reforming; aromatics recovery; catalytic cracking; alkylation; delayed coking; 
hydrogen production; and sulfur recovery. Refining operations began at the site in 1917 and the operating units now present include 
both newly constructed units and older units that have been upgraded over the years.

The Tulsa West facility is located on a 750-acre site in Tulsa, Oklahoma situated along the Arkansas River. The principal processing 
units at the Tulsa West facility consist of crude and vacuum distillation (with light ends recovery), naphtha hydrodesulfurization, 
propane de-asphalting, lubes extraction, MEK dewaxing, delayed coker and butane splitter units. Most of the operating units at 
the facility currently in service were built in the late 1950s and early 1960s. The refinery was reconfigured to emphasize specialty 
lubricant production in the early 1990s.

The Tulsa East facility is located on a 466-acre site also in Tulsa, Oklahoma situated along the Arkansas River. The principal 
process units at the Tulsa East facility consist of crude and vacuum distillation, naphtha hydrodesulfurization, FCC, isomerization, 
catalytic reforming, alkylation, scanfiner, diesel hydrodesulfurization and sulfur units.

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. Additionally, HEP's on-site truck and rail racks facilitate access to local 
refined product markets.

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.

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, 2017, sales to Sinclair represented approximately 21% of the Tulsa Refineries’ total sales and 8% 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.

For the year ended December 31, 2017, sales to Shell Oil represented approximately 12% of our Mid-Continent refineries’ total 
sales and 9% of our total consolidated sales. We have a sales agreement with an affiliate of Shell Oil under which Shell Oil 
purchases gasoline and diesel production of the El Dorado Refinery and Tulsa Refineries at market prices through October 2018 
primarily to support its branded marketing network.

Crude Oil and Feedstock Supplies
Both of our Mid-Continent Refineries are connected via pipeline to Cushing, Oklahoma, a significant crude oil pipeline trading 
and storage hub. The El Dorado Refinery and the Tulsa Refineries are located approximately 125 miles and 50 miles, respectively, 
from Cushing, Oklahoma. Local pipelines provide direct access to regional Oklahoma crude production as well as access to United 
States onshore and Canadian crudes. The proximity of the refineries to the Cushing pipeline and storage hub provides the flexibility 
to optimize their crude slate with a wide variety of crude oil supply options. Additionally, we have transportation service agreements 
to transport Canadian crude oil on the Spearhead and Keystone Pipelines, enabling us to transport Canadian crude oil to Cushing 
for subsequent shipment to either of our Mid-Continent Refineries. 

We also purchase isobutane, natural gasoline, butane and other feedstocks for processing at our Mid-Continent Refineries. The El 
Dorado Refinery is connected to Conway, Kansas, a major gas liquids trading and storage hub, via the Oneok Pipeline. From time 
to time, other feedstocks such gas oil, naphtha and light cycle oil are purchased from other refiners for use at our refineries.

The Navajo Refinery's Artesia, New Mexico facility is located on a 561-acre site and is a fully integrated refinery with crude 
distillation, vacuum distillation, FCC, ROSE (solvent deasphalter), HF alkylation, catalytic reforming, hydrodesulfurization, mild 
hydrocracking, isomerization, sulfur recovery and product blending units. The operating units at the Artesia facility include newly 
constructed units, older units that have been relocated from other facilities and upgraded and re-erected in Artesia, and units that 
have been operating as part of the Artesia facility (with periodic major maintenance) for many years, in some very limited cases 
since before 1970.

The Artesia facility is operated in conjunction with a refining facility located in Lovington, New Mexico, approximately 65 miles 
east of Artesia. The principal equipment at the Lovington facility consists of a crude distillation unit and associated vacuum 
distillation units that were constructed after 1970. The Lovington facility processes crude oil into intermediate products that are 
transported to Artesia by means of three intermediate pipelines owned by HEP. These products are then upgraded into finished 
products at the Artesia facility. The combined crude oil capacity of the Navajo Refinery facilities is 100,000 BPSD and it typically 
processes or blends an additional 10,000 BPSD of natural gasoline, butane, gas oil and naphtha.

Markets and Competition 
The Navajo Refinery primarily serves the southwestern United States market, including the metropolitan areas of El Paso, Texas; 
Albuquerque, Moriarty and Bloomfield, New Mexico; Phoenix and Tucson, Arizona; and portions of northern Mexico. Our products 
are shipped through HEP's pipelines from Artesia, New Mexico to El Paso, Texas and from El Paso to Albuquerque and to Mexico 
via products pipeline systems owned by Magellan and from El Paso to Tucson and Phoenix via a products pipeline system owned 
by Kinder Morgan's subsidiary, SFPP, L.P. (“SFPP”). In addition, petroleum products from the Navajo Refinery are transported 
to markets in northwest New Mexico, to Moriarty, New Mexico, near Albuquerque, via HEP's pipelines running from Artesia to 
San Juan County, New Mexico, and to Bloomfield, New Mexico. We have refined product storage through our pipelines and 
terminals agreement with HEP at terminals in Tucson, Arizona, and Artesia and Moriarty, New Mexico.

hydrogen production, sulfur recovery and product blending units. The operating units at the Cheyenne Refinery include both newly 
constructed units and older units that have been upgraded over the years.

The Woods Cross Refinery facility is located on a 200-acre site and is a fully integrated refinery with crude distillation, solvent 
deasphalter, FCC, HF alkylation, catalytic reforming, hydrodesulfurization, isomerization, sulfur recovery and product blending 
units. The operating units at the Woods Cross Refinery include newly constructed units, older units that have been relocated from 
other facilities, upgraded and re-erected in Woods Cross, and units that have been operating as part of the Woods Cross facility 
(with periodic major maintenance) for many years, in some very limited cases since before 1950. The facility typically processes 
or blends an additional 2,000 BPSD of natural gasoline, butane and gas oil over its 45,000 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.

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.

Pipeline. In addition to our Woods Cross Refinery, local area refiners include Chevron, Andeavor, 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 165,000 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 Andeavor Logistics 
Northwest Pipelines LLC (“Andeavor 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 Andeavor 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.

relations, governmental affairs, accounting, tax, treasury, information technology, legal and human resources support functions. 

Employees and Labor Relations
As of December 31, 2017, we had 3,522 employees, of which 1,139 are currently covered by collective bargaining agreements 
having various expiration dates between 2018 and 2020. We consider our employee relations to be good.

Environmental Regulation
We are subject to numerous federal, state, provincial and local laws regulating worker health and safety, the discharge of substances 
into the environment, or otherwise relating to the protection of the environment and natural resources. Permits or other authorizations 
are required under these laws for the operation of our refineries, pipelines and related facilities, which can result in the imposition 
of  costly  reporting,  installation  of  pollution  control  equipment  and  maintenance  obligations.  Moreover,  these  permits  and 
authorizations are subject to revocation, modification and renewal, as well as challenges from third parties.

Failure to comply with these laws and regulations may result in the assessment of sanctions, including administrative, civil and 
criminal  penalties;  the  imposition  of  investigatory,  remedial  or  corrective  action  obligations  or  the  incurrence  of  capital 
expenditures; the occurrence of delays in the permitting, development or expansion of projects; and the issuance of injunctive 
relief limiting or prohibiting certain operations. 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 expenditures.

Clean Air Act - Our operations 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, operational procedures to minimize emissions, and monitoring and reporting 
of  emissions. Additionally,  the  Environmental  Protection Agency  (“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. Also, in October 2015, the EPA lowered the National Ambient Air Quality Standard (“NAAQS”) for ozone from 75 to 70 
parts per billion, and state implementation of the revised NAAQS could result in stricter permitting requirements, delay or the 
inability to obtain such permits, and increased expenditures for pollution control equipment, the costs of which could be significant. 
Moreover, in February 2016, a new EPA rule became effective that requires, among other things, benzene monitoring at the refinery 
fence line beginning in January 2018 and submittal of fence line monitoring data to the EPA on a quarterly basis; upgraded storage 
tank controls requirements, including new applicability thresholds; enhanced performance requirements for flares, continuous 
monitoring of flares and pressure release devices, and analysis and remedy of flare release events; compliance with emissions 
standards for delayed coking units; and requirements related to air emissions resulting from startup, shutdown and maintenance

events. These new rules, 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 and result in increased costs on our operations.

Fuel Quality Regulation - 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 benzene 
credits to meet these requirements. If economically justified or otherwise determined to be beneficial, we could implement additional 
benzene reduction projects to eliminate the need to purchase benzene credits. 

Pursuant to the Energy Independence and Security Act of 2007 (“EISA”), and the EPA’s corresponding Renewable Fuel Standard 
(“RFS”) regulations, most refiners are required to blend increasing amounts of biofuels with refined products through 2022 or 
purchase Renewable Identification Numbers (“RINs”) in lieu of blending. Under the RFS, the percentage of renewable fuels that 
refineries are obligated to blend into their finished petroleum products is adjusted annually. In November 2017, the EPA finalized 
the RFS targets for 2018, which maintained the volume required for conventional (i.e., corn ethanol) renewable fuel, increased 
the volume required for advanced biofuels, and reduced the volume required for cellulosic biofuel compared to the 2017 RFS 
requirements. The EPA also maintained the biomass-based diesel volume for 2019 compared to 2018. Because the EISA requires 
specified volumes of biofuels, if the demand for motor fuels decreases in future years, even higher percentages of biofuels may 
be required.

The EPA has historically used its waiver authority to establish volumes lower than the statutory volumes required by EISA, but 
the EPA’s interpretation of its waiver authority, as well as its implementation of the RFS, has been subject to numerous court 
challenges. Additional lawsuits have been filed by refiners attempting to move the point of compliance for the RFS from refiners 
to importers and blenders of fuels. We cannot predict the outcome of these matters or whether they may result in increased RFS 
compliance costs. There also continues to be a shortage of advanced biofuel production resulting in increased difficulties meeting 
RFS mandates. As a result, we may be unable to blend sufficient quantities of ethanol and biodiesel to meet our requirements and, 
therefore, may have to purchase an increasing number of RINs. It is not possible at this time to predict with certainty what those 
volumes or costs may be, but given the potential increase in volumes and the volatile price of RINs, increases in renewable volume 
requirements could have an adverse impact on our results of operations.

Finally, while there is no current regulatory standard that authenticates RINs that may be purchased on the open market from third 
parties, we believe that the RINs we purchase are from reputable sources, are valid and serve to demonstrate compliance with 
applicable RFS requirements. However, if any of the RINs purchased by us on the open market are subsequently found by the 
EPA to be invalid, we could secure significant costs, penalties, or other liabilities in connection with replacing any invalid RINs 
and resolving any enforcement action brought by the EPA.

In April 2014, the EPA promulgated the Tier 3 Motor Vehicle Emission and Fuel Standards, which requires a reduction in annual 
average gasoline sulfur content from 30 ppm to 10 ppm. These new requirements, other CAA requirements, and other presently 
existing or future environmental regulations may cause us to make substantial capital expenditures and purchase sulfur credits at 
significant cost to enable our refineries to produce products that meet applicable requirements.

Climate Change - In recent years, various legislative and regulatory measures to address climate change and greenhouse gas 
(“GHG”) emissions (including carbon dioxide, methane and nitrous oxides) have been discussed or implemented. They include 
proposed and enacted federal regulation and state actions to develop statewide, regional or nationwide programs designed to 
control and reduce GHG emissions from fixed sources, such as our refineries, as well as power plants, mobile transportation 
sources and fuels. Measures to date have included cap and trade programs, carbon taxes, vehicle efficiency standards and low 
carbon fuel standards. Although it is not possible to predict the requirements of any GHG legislation that may be enacted, any 
laws or regulations that may be adopted to restrict or reduce GHG emissions will likely require us to incur increased operating 
and capital costs. In August 2015, the EPA finalized the “Clean Power Plan” requiring states to reduce carbon dioxide emissions 
from coal fired power plants that will likely result in a combination of plant closures, switching to renewable energy and natural 
gas, and demand reduction. However, the Clean Power Plan is currently being litigated in various courts, and the U.S. Supreme 
Court has stayed implementation of the rule pending the outcome of those judicial challenges. In October 2017, the EPA proposed 
to repeal the Clean Power Plan, and on December 18, 2017, the EPA issued a notice seeking comments on whether to promulgate 
a replacement rule. If upheld, this rule would not directly affect our operations, but, to the extent it or a similar rule is fully 
implemented, it could result in increased power costs for our refineries in future years.

19

EPA rules require us to report GHG emissions from our refinery operations and consumer use of fuel products produced at our 
refineries on an annual basis. While the cost of compliance with the reporting rule is not material, data gathered under the rule 
may be used in the future to support additional regulation of GHG. Moreover, the EPA directly regulates GHG emissions from 
refineries and other major sources through the Prevention of Significant Deterioration (“PSD”) and Federal Operating Permit 
programs and may require Best Available Control Technology (“BACT”) for GHG emissions above a certain threshold if emissions 
of other pollutants would otherwise require PSD permitting. While this does not impose any limits or controls on GHG emissions 
from current operations, future projects or operational changes that increase GHG emissions, such as capacity increases, may be 
subject to emission limits or technological requirements pertaining to GHG emissions, such as BACT. 

Severe limitations on GHG emissions could also adversely affect demand for the gasoline that we produce. Recently, activists 
concerned about the potential effects of climate change have directed their attention at sources of funding for fossil-fuel energy 
companies, which has resulted in certain financial institutions, funds and other sources of capital restricting or eliminating their 
investment in oil and natural gas activities. Ultimately, this could make it more difficult to secure funding for exploration and 
production activities and result in decreased production of oil, which indirectly could have an adverse impact on our operations. 
Notwithstanding potential risks related to climate change, the International Energy Agency estimates that global energy demand 
will continue to rise and will not peak until after 2040 and that oil and natural gas will continue to represent a substantial percentage 
of global energy use over that time. Finally, it should be noted that 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, floods and other extreme weather events; if any such effects were to occur, they could have an adverse 
effect on our operations.

Water Discharges - 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. The EPA commenced a study from 2015-2017 related to the discharges of metals 
and dioxin from petroleum refining operations and wastewater discharges from refineries in connection with the consideration of 
new effluent limitation guidelines that would be incorporated into refinery sector NPDES permits. To date, the EPA has not proposed 
any new effluent limitation guidelines applicable to our operations, but future rulemakings related to this issue could require us 
to incur increased costs related to the treatment of wastewater resulting from our operations.

The CWA also regulates filling or discharges to wetlands and other “Waters of the U.S.” In 2015, the EPA, in conjunction with 
the U.S. Army Corps of Engineers (the “Corps”), issued a final rule regarding the definition of “Waters of the U.S.,” which expanded 
the regulatory reach of the existing CWA regulations. The final rule is currently stayed pending litigation in various courts, and 
the EPA has expressed its intent to repeal and potentially replace the rule. If the rule or any replacement rule expands the scope 
of the CWA’s jurisdiction, we could face increased costs and delays with respect to obtaining permits for discharges resulting from 
our operations.

Hazardous Substances and Wastes - 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. Although the EPA is currently working on several rulemakings that could impact 
how our refineries manage various waste streams, it does not appear that these rules will significantly impact our refineries.

The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), also known as “Superfund,” imposes 
strict, and under certain circumstances, joint and several liability on certain classes of persons who are considered to be responsible 
for the cost of cleaning up hazardous substances that have been released into the environment and for damages to natural resources. 
These persons include current and former owners or operators of property where a release has occurred, and any persons who 
disposed of, or arranged for the transport or disposal of, hazardous substances at the property. In the course of our historical 
operations, as well as in our current 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 in the future. 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. 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.  

20

Oil Pollution Act - The Oil Pollution Act of 1990 (“OPA”) and regulations thereunder generally subject owners and operators of 
facilities  to  strict,  joint  and  several  liability  for  all  containment  and  cleanup  costs,  natural  resource  damages,  and  potential 
governmental oversight costs arising from oil spills into the waters of the U.S. The OPA also imposes ongoing requirements on a 
responsible party, including the preparation of oil spill response plans and proof of financial responsibility to cover environmental 
cleanup and restoration costs that could be incurred in connection with an oil spill.

Our Canadian assets and operations are also required to comply with various Canadian federal, provincial and municipal regulations. 
The regulations are in many cases conceptually similar to those described above for our U.S. operations. The principal legislation 
affecting our Canadian operations is the Canadian Environmental Protection Act and its regulations at a federal level and various 
provincial statutes and regulations such as the Ontario Environmental Protection Act, the Ontario Occupational Health and Safety 
Act and the Ontario Water Resources Act. All these laws contain broad prohibitions against causing harm to air, land, water, people 
or any other living organism and in many cases contain detailed prescriptive rules governing many aspects of our operations.

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, GHG emissions, personal 
injury and property damage allegedly caused by substances that we manufactured, handled, used, released or disposed. 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, 2017, we had an accrual of $103.7 million related to 
such environmental liabilities.

We are and have been the subject of various local, state, provincial, 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.

Occupational Health and Safety - Our operations are subject to various laws and regulations relating to occupational health and 
safety, including the Occupational Safety and Health Act (“OSHA”) and comparable state statutes. We maintain a comprehensive 
safety program, including mechanical integrity and safety-related maintenance programs and training, to ensure compliance with 
all applicable laws and regulations to protect the safety of our workers and the public. Our operations are also subject to OSHA 
Process Safety Management (“PSM”) regulations and EPA Risk Management Plan (“RMP”) regulations, both of which are designed 
to prevent or minimize the consequences of catastrophic releases of toxic, reactive, flammable or explosive chemicals. In January 
2017, the EPA revised the RMP requirements for incident investigation and accident history reporting, emergency preparedness, 
and the performance process hazard analyses and third party compliance audits. In June 2017, the EPA issued a stay of the revised 
RMP requirements until 2019, which was immediately challenged by environmental groups, and a final decision remains pending. 
However, many of the revised requirements do not become effective until 2021. Also in January 2017, OSHA announced changes 
to its National Emphasis Program, which specifically identified oil refineries as facilities for increased inspections and instructed 
inspectors to use data gathered from EPA RMP inspections to identify refiners for additional PSM inspections. Compliance with 
applicable state and federal occupational health and safety laws and regulations, as well as environmental regulations, has required, 
and continues to require, substantial expenditures.

Occupational health and environmental legislation, regulations and regulatory programs change frequently. We cannot predict 
what additional occupational 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 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 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 availability and cost of renewable identification numbers and other required credits could have an adverse effect on our 
financial condition and results of operations. 

Pursuant to the 2007 Energy Independence and Security Act, the EPA promulgated the RFS 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. 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 RFS regulations. 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 RFS 
regulations 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 RFS mandates, our financial condition and results of operations could be adversely 
affected.

In addition, the RFS regulations are highly complex and evolving, requiring us to periodically update our compliance systems. The 
RFS  regulations  require  the  EPA  to  determine  and  publish  the  applicable  annual  volume  and  percentage  standards  for  each 
compliance year by November 30 for the forthcoming year, and such blending percentages could be higher or lower than amounts 
estimated and accrued for in our consolidated financial statements. The future cost of RINs is difficult to estimate until such time 
as the EPA finalizes the applicable standards for the forthcoming compliance year. Moreover, in addition to increased price volatility 
in the RIN market, there have been multiple instances of RINs fraud occurring in the marketplace over the past several years. The 
EPA has initiated several enforcement actions against refiners who purchase fraudulent RINs, resulting in substantial costs to the 
refiner. 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 RFS regulations will impact our future results of operations.

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, crude 
oil  differentials  (including  regional  and  grade  differentials),  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. 

22

Table of Content

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. Also, in 
December 2015, the U.S. Congress lifted the ban on the ability of producers to export domestic crude oil. This could potentially 
impact crack spreads and price differentials between domestic and foreign crude oils. A deterioration of crack spreads or price 
differentials between domestic and foreign crude oils could have a material adverse effect on our business, financial condition, 
results of operations and cash flows. 

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. Continued volatility in crude oil and refined products prices could result 
in lower of cost or market inventory charges in the future, or in reversals reducing cost of products sold in subsequent periods 
should prices recover. For example, we recorded a non-cash decrease to cost of products sold in the amount of $108.7 million and 
$291.9 million for the years ended December 31, 2017 and 2016, respectively.

A material decrease in the supply of crude oil or other raw materials available to our refineries could significantly reduce our 
production levels and negatively affect our operations. 

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. 

For certain raw materials and utilities used by our refineries, there are a limited number of suppliers and, in some cases, the supplies 
are specific to the particular geographic region in which a facility is located. It is also common in the refining industry for a facility 
to have a sole, dedicated source for its utilities, such as steam, electricity, water and gas. Having a sole or limited number of 
suppliers may limit our negotiating power, particularly in the case of rising raw material costs. Any new supply agreements we 
enter into may not have terms as favorable as those contained in our current supply agreements.

Additionally, there is growing concern over the reliability of water sources. The decreased availability or less favorable pricing 
for water as a result of population growth, drought or regulation could negatively impact our operations.

If our raw material, utility or water supplies were disrupted, our businesses may incur increased costs to procure alternative supplies 
or incur excessive downtime, which would have a direct negative impact on our operations.

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: 

• 

• 
• 
• 
• 
• 

third party challenges to, denials, or delays with respect to the issuance of requisite regulatory approvals and/or obtaining 
or renewing permits, licenses, registrations and other authorizations;
societal and political pressures and other forms of opposition;
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 or businesses 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;
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.

Currency fluctuations or devaluations may impact our operating results.

Fluctuations or devaluations in foreign currencies relative to the U.S. dollar can impact our revenue and our costs of doing business. 
Most of our products and services are sold through contracts denominated in U.S. dollars; however, some of our revenue, local 
expenses and manufacturing costs are incurred in local currencies and, therefore, changes in the exchange rates between the U.S. 
dollar and foreign currencies can increase or decrease our revenue and expenses reported in U.S. dollars and may impact our 
results of operations. Any significant change in the value of the currencies of the countries in which we do business against the 
U.S. dollar could affect our competitiveness and control of our cost structure, which could have a material adverse effect on our 
business, financial condition and results of operations.

We are exposed to fluctuations in foreign currency exchange rates, particularly with respect to the Canadian dollar, the euro and 
the Chinese renminbi. We recognize foreign currency transaction gains and losses arising from our operations in the period incurred. 
As a result, currency fluctuations between the U.S. dollar and the currencies in which we do business have caused and will continue 
to cause foreign currency transaction and translation gains and losses, which could be material. We cannot predict the effects of 
exchange rate  fluctuations upon  our  future  operating  results  because of  the  number  of  currencies involved,  the  variability of 
currency exposures and the potential volatility of currency exchange rates

Our business is subject to the risks of international operations. 

We derive a portion of our revenue and earnings from international operations. Compliance with applicable U.S. and foreign laws 
and regulations, such as import and export requirements, anti-corruption laws, foreign exchange controls and cash repatriation 
restrictions, data privacy requirements, environmental laws, labor laws and anti-competition regulations, increases the cost of 
doing business in foreign jurisdictions. Although we have implemented policies and procedures to comply with these laws and 
regulations, a violation by any of our employees, contractors or agents could nevertheless occur. In some cases, compliance with 
the laws and regulations of one country could violate the laws and regulations of another country. Violations of these laws and 
regulations could materially adversely affect our company's brand, international growth efforts and business.

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. 

Our refinery and pipeline operations are subject to federal, state and local laws regulating, among other things, the generation, 
storage, handling, use, transportation and distribution 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. In addition, as a result of our recent 
acquisition of PCLI, we have manufacturing and distribution operations in Canada that are subject to Canadian national and 
provincial environmental laws and regulations and similar laws in other foreign countries. 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. For example, in October 
2015, the EPA lowered the NAAQS for ozone from 75 to 70 parts per billion for both the 8-hour primary and secondary standards. 
The EPA published a final rule in November 2017 that issued area designations with respect to ground level ozone for approximately 
85% of the U.S. counties as either “attainment/unclassifiable” or “unclassifiable.” In December 2017, the EPA responded to states' 
preliminary non-attainment designations, and expects to issue final non-attainment designations during the first half of 2018. State 
implementation of the revised NAAQS could result in stricter permitting requirements, delay or prohibit our ability to obtain such 
permits, and result in increased expenditures for pollution control equipment, the costs of which could be significant. Also, in 
February 2016, a new EPA rule became effective that amends three refinery standards already in effect, imposing additional or, 
in some cases, new emission control requirements on subject refineries. The final rule requires, among other things, benzene 
monitoring at the refinery fence line and submittal of fence line monitoring data to the EPA on a quarterly basis; upgraded storage 
tank controls requirements, including new applicability thresholds; enhanced performance requirements for flares, continuous 
monitoring of flares and pressure release devices and analysis and remedy of flare release events; and compliance with emissions 
standards for delayed coking units. Refineries have up to three years from the effective date of the final rule to come into compliance 
with certain requirements of the rule, such as the performance requirements for flares, while other aspects of the rule require 
compliance to be achieved at a sooner date. For example, the rule's fence line monitoring requirements became effective January 
31, 2018. In July 2016, the EPA issued a finale rule providing refiners an additional 18 months to comply with a small subset of 
the rules related to air emissions resulting from startup, shutdown and maintenance events. In December 2016, the EPA granted 
petitions for reconsideration from industry and environmental organizations on aspects of the rule related to work practice standards 
25

Table of Content

for certain process units and equipment, as well as fence line monitoring requirements. To date, EPA has not published revised 
rules. These new rules, 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 and result in increased costs on our operations. 
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 local, state, provincial, 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 but 
cannot guarantee that these efforts will always be successful. 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.

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 or the Federal or Provincial Governments 
of Canada. 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. In Canada, fuel content legislation also exists at the federal and provincial level. 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 or regulations could result in increased operating costs and reduced demand for 
the refined products we produce.

The EPA has determined that emissions of carbon dioxide, methane and other greenhouse gas emissions, or “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 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. Both the EPA and Environment and Climate Change Canada have adopted regulations 
that limit GHG emissions from automobiles and light-duty trucks, which may result in a reduction in demand for the refined 
products that we produce.

26

Table of Content

Although the U.S. Congress has previously considered legislation to reduce GHG emissions, federal legislative action appears 
unlikely at this time. Meanwhile, many states have pursued or are considering their own initiatives designed to reduce GHG 
emissions, such as cap and trade programs, carbon taxes, low carbon fuel standards, and vehicle efficiency standards. Similar 
measures are being pursued in Canada at the federal and provincial level, and the provinces of Quebec, Ontario, and Alberta have 
all implemented either cap and trade programs or levied carbon taxes.

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. 

Our operations are subject to catastrophic losses, operational hazards and unforeseen interruptions for which we may not be 
adequately insured. 

Our operations are subject to catastrophic losses, operational hazards and unforeseen interruptions such as natural disasters, adverse 
weather, accidents, maritime disasters (including those involving marine vessels/terminals), fires, explosions, hazardous 
materials releases, cyber-attacks, power failures, mechanical failures and other events beyond our control. These events could 
result in an injury, loss of life, property damage or destruction, as well as a curtailment or an interruption in our operations and 
may affect our ability to meet marketing commitments. 

We may not be able to maintain or obtain insurance of the type and amount we desire at reasonable rates and exclusions from 
coverage may limit our ability to recover the amount of the full loss in all situations. As a result of market conditions, premiums 
and deductibles for certain of our insurance policies could increase. In some instances, certain insurance could become unavailable 
or available only for reduced amounts of coverage. We are  not fully insured against all risks incident to our business and therefore, 
we self-insure certain risks. 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 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. If a significant accident or event occurs that is self-
insured or not fully insured, it could have a material adverse effect on our business, financial condition and results of operations.

An impairment of our long-lived assets or goodwill could reduce our earnings or negatively impact our financial condition 
and results of operations. 

An impairment of our long-lived assets or goodwill could reduce our earnings or negatively impact our results of operations and 
financial condition. We continually monitor our business, the business environment and the performance of our operations to 
determine if an event has occurred that indicates that a long-lived asset or goodwill may be impaired. If a triggering event occurs, 
which is a determination that involves judgment, we may be required to utilize cash flow projections to assess our ability to recover 
the carrying value based on the ability to generate future cash flows. We may also conduct impairment testing based on both the 
guideline public company and guideline transaction methods. Our long-lived assets and goodwill impairment analyses are sensitive 
to changes in key assumptions used in our analysis, estimates of future crack spreads, forecasted production levels, operating costs 
and capital expenditures. If the assumptions used in our analysis are not realized, it is possible a material impairment charge may 
need to be recorded in the future. We cannot accurately predict the amount and timing of any additional impairments of long-lived 
assets or goodwill in the future. 

27

Table of Content

As market prices for refined products and market prices for crude oil continue to fluctuate, we will need to continue to evaluate 
the carrying value of our refinery reporting units. During the year ended December 31, 2016, we recorded goodwill and long-
lived asset impairment charges of $309.3 million and $344.8 million, respectively, on the carrying value of our Cheyenne Refinery. 
A reasonable expectation exists that future deterioration in gross margins could result in an impairment of goodwill and the long-
lived assets of the El Dorado reporting unit at some point in the future. Any additional impairment charges that we may take in 
the future could be material to our results of operations and financial condition.

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. 

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.

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. Recently, the equity and debt markets for many energy 
industry companies have been adversely affected by low oil prices. 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. 

At December 31, 2017, we owned a 59% limited partner interest and a non-economic general partner interest in HEP. HEP operates 
a system of crude oil and petroleum product pipelines; distribution terminals and refinery tankage in Arizona, Idaho, Kansas, 
Nevada, New Mexico, Oklahoma, Texas, Utah, Washington and Wyoming and refinery units in Kansas and Utah. HEP generates 
revenues by charging tariffs for transporting petroleum products and crude oil through its pipelines, leasing certain pipeline capacity 
to Delek, 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 2020 through 2036, serves the El Dorado Refinery under long-term 
tolling agreements expiring in 2030 and serves the Woods Cross Refinery under long-term tolling agreements expiring in 2031. 
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, 2017.

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.

29

Table of Content

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.  

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 (including cyber-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  and  the  threat  of  future  terrorist  attacks  (including  cyber-attacks)  on  the  energy 
transportation industry in general, and on us in particular, are unknown. Increased security measures taken by us as a precaution 
against possible terrorist attacks or vandalism have resulted in increased costs to our business. Uncertainty surrounding continued 
global hostilities or other sustained military campaigns, and the possibility that infrastructure facilities could be direct targets of, 
or indirect casualties of, an act of terror, may affect our operations in unpredictable ways, including disruptions of crude oil supplies 
and markets for refined products. 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. In 2017, the EPA and 
NHTSA announced that the agencies were reconsidering the second phase CAFE standards, which could result in maintaining the 
first phase standards for the 2022-2025 model years. A final decision is expected during the first half of 2018. Any 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.

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 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 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 or amounts 
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. 

31

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 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, 2017, 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, industry 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.

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, provincial 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. 

Cheyenne
HollyFrontier  Cheyenne  Refining  LLC  (“HFCR”)  has  been  engaged  in  discussions  with  the  Wyoming  Department  of 
Environmental  Quality  (“WDEQ”)  relating  to  a  Notice  of Violation  issued  in  late  2016  for  possible  violations  of  air  quality 
standards related to operation of certain refinery units at the Cheyenne Refinery in 2016 and 2017. HFCR and the WDEQ are 
working towards a settlement of this matter.

El Dorado
The El Dorado Refinery is engaged in discussions with, and has responded to document requests from, the EPA and the U.S. 
Department of Justice (“DOJ”) regarding potential Clean Air Act violations relating to flaring devices and other equipment at the 
refinery. Topics of the discussions include (a) three information requests for activities occurring January 1, 2009 through May 31, 
2014 and a September 2017 incident, (b) Risk Management Program compliance issues relating to a November 2014 inspection 
and (c) a Notice of Violation issued by the EPA in August 2017. We will continue to work with the EPA and DOJ to resolve these 
matters.

Tulsa
HollyFrontier Tulsa Refining LLC (“HFTR”) manufactures paraffin and hydrocarbon waxes at its Tulsa West facility. On March 
11, 2014, the EPA issued a notice to HFTR of possible violations of certain provisions of the federal Toxic Substances Control 
Act in connection with the manufacture of certain of these products. HFTR and the EPA met and are working productively towards 
a settlement of this matter.

HFTR operates under two Consent Decrees with the EPA and the Oklahoma Department of Environmental Quality (“ODEQ”). 
On December 13, 2017, during a meeting between the parties, ODEQ proposed stipulated penalties related to violations of the 
two Consent Decrees. The violations relate to Clean Air Act regulated fuel gas and flare operations. HFTR is currently negotiating 
with the ODEQ and the EPA.

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 7.  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 nameplate 
crude oil processing capacity of 457,000 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, Artesia, New Mexico, which 
operates in conjunction with crude, vacuum distillation and other facilities situated 65 miles away in Lovington, New Mexico 
(collectively, the Navajo Refinery), Cheyenne, Wyoming (the Cheyenne Refinery) and Woods Cross, Utah (the Woods Cross 
Refinery).

On October 29, 2016, our wholly-owned subsidiary, 9952110 Canada Inc., entered into a share purchase agreement with Suncor 
to acquire 100% of the outstanding capital stock of PCLI. The acquisition closed on February 1, 2017. Cash consideration paid 
was $862.1 million, or $1.125 billion in Canadian dollars.

PCLI is a Canadian-based producer of base oils with a plant having 15,600 BPD of lubricant production capacity that is located 
in Mississauga, Ontario. The facility is downstream integrated from base oils to finished lubricants and produces a broad spectrum 
of specialty lubricants and white oils that are distributed to end customers worldwide through a global sales network with locations 
in Canada, the United States, Europe and China.

For the year ended December 31, 2017, net income attributable to HollyFrontier stockholders was $805.4 million compared to a 
net loss of $260.5 million and net income $740.1 million for the years ended December 31, 2016, and 2015, respectively. Overall 
gross refining margins per barrel sold for 2017 increased 42% over the year ended December 31, 2016, which was due principally 
to higher crack spreads throughout 2017. Included in our financial results for the current year was a long-lived asset impairment 
charge, offset by an inventory reserve adjustment.

Pursuant to the 2007 Energy Independence and Security Act, the EPA promulgated the RFS 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. Compliance with RFS regulations significantly increases our cost of products sold, with RINs costs totaling $288.4 
million for the year ended December 31, 2017, which is net of the $57.7 million cost reduction resulting from reinstatement of 
2016 RINs as described in Note 8 “Inventories” in the Notes to Consolidated Financial Statements.

OUTLOOK

The profitability of our refining business is largely driven by our operational reliability and crack spreads (the price difference 
between refined products and inputs such as crude oil), which are driven by the supply and demand of refined product markets. 
In 2017, crack spreads showed material improvement over 2016 as global and North American refined product market supply and 
demand tightened. Going into 2018, we are anticipating continued demand growth for refined products and are optimistic about 
margins. Additionally, we expect to benefit from widening crude differentials on some of our key inputs in the Refining segment: 
Cushing-based crude oils and Canadian heavy crude oils. 

Our lubricants business is driven by secular demand for higher quality lubricants and greases, cyclical macroeconomic factors 
and our own operational reliability. In 2017, we acquired and integrated the Petro-Canada Lubricants business into our business 
and going into 2018, we anticipate strong earnings growth based on continued economic growth as well as the execution of our 
organic growth strategy.

36

Table of Content

HEP’s business is largely driven by the operational reliability of our refineries and contractual tariff increases. Based on our volume 
forecasts, we expect HEP to be able to grow its limited partner distribution approximately 4% with a distribution coverage ratio 
of roughly 1.0x.

A more detailed discussion of our financial and operating results for the years ended December 31, 2017, 2016 and 2015 is presented 
in the following sections.

(1)  Earnings before interest, taxes, depreciation and amortization, which we refer to as “EBITDA,” is calculated as net income 
(loss) 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 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. EBITDA presented above is reconciled to net income under “Reconciliations to Amounts Reported 
Under Generally Accepted Accounting Principles” following Item 7A of Part II of this Form 10-K.

Supplemental Segment Operating Data

Effective in the fourth quarter of 2017, we revised our reportable segments to align with certain changes in how our chief operating 
decision maker manages and allocates resources to our business. Accordingly, our Tulsa Refineries lubricants operations, previously 
reported in the Refining segment, are now combined with the operations of our Petro-Canada Lubricants business and reported 
in the Lubricants and Specialty Products segment. Our prior period segment information has been retrospectively adjusted to 
reflect our current segment presentation.

Our operations are organized into three reportable segments, Refining, Lubricants and Specialty Products and HEP. See Note 20 
“Segment Information” in the Notes to Consolidated Financial Statements for additional information on our reportable segments.

Refining Segment Operating Data

Our refinery operations include the El Dorado, Tulsa, Navajo, Cheyenne and Woods Cross Refineries. The following tables set 
forth information, including non-GAAP performance measures, about our consolidated refinery operations. The cost of products 
and refinery gross and net operating margins do not include the non-cash effects of goodwill and asset impairments charges, lower 
of cost or market inventory valuation adjustments and depreciation and amortization. Reconciliations to amounts reported under 
GAAP are provided under “Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles” following 
Item 7A of Part II of this Form 10-K.

During the fourth quarter of 2017, we revised the following refining segment operating data computations: refinery gross margin; 
net operating margin; and operating expenses to better align with  similar measurements provided by  other companies in our 
industry  and  to  facilitate  comparison  of  our  refining  performance  relative  to  our  peers.  Effective  with  this  change,  these 
measurements are now inclusive of all refining segment activities including HFC asphalt operations and revenues and costs related 
to products purchased for resale and excess crude oil sales. All prior period data has been retrospectively adjusted to reflect our 
current presentation.

Results of Operations – Year Ended December 31, 2017 Compared to Year Ended December 31, 2016 

Summary
Net income attributable to HollyFrontier stockholders for the year ended December 31, 2017 was $805.4 million ($4.54 per basic 
and $4.52 per diluted share), a $1,065.8 million increase compared to a net loss attributable to HollyFrontier stockholders of $260.5 
million ($1.48 per basic and diluted share) for the year ended December 31, 2016. Net income increased due principally to an 
increase in refining segment sales volumes and gross refining margins and the inclusion of earnings attributable to the operations 
of our recently acquired Petro-Canada Lubricants business. Additionally, we recorded long-lived asset impairment charges totaling 
$23.2 million for the year ended December 31, 2017 compared to goodwill and long-lived asset impairment charges totaling $654.1 
million for the year ended December 31, 2016. For the year ended December 31, 2017, lower of cost or market inventory reserve 
adjustments increased pre-tax earnings by $108.7 million compared to $291.9 million for the year ended December 31, 2016. 
Refinery gross margins for the year ended December 31, 2017 increased to $11.56 per barrel sold from $8.16 for the year ended 
December 31, 2016. During 2017, our Cheyenne Refinery and Woods Cross Refinery were each granted a one-year small refinery 
exemption from the EPA at which time we recorded a $30.5 million and $27.3 million, respectively, decrease to our cost of products 
sold, reflecting the reinstatement of RINs previously expensed in 2016. The Tax Cut and Jobs Act was enacted on December 22, 
2017, resulting in a tax benefit of $307.1 million for the year ended December 31, 2017.

Sales and Other Revenues
Sales and other revenues increased 35% from $10,535.7 million for the year ended December 31, 2016 to $14,251.3 million for 
the year ended December 31, 2017 due to a year-over-year increase in sales prices and higher product sales volumes. Sales and 
other revenues for the years ended December 31, 2017 and 2016 include $77.2 million and $68.9 million, respectively, in HEP 
revenues attributable to pipeline and transportation services provided to unaffiliated parties. Additionally, the operations of our 
Petro-Canada Lubricants business contributed $1,125.3 million in sales and other revenues to our Lubricants and Specialty Products 
segment for the year ended December 31, 2017.

Cost of Products Sold
Total cost of products sold increased 34% from $8,474.0 million for the year ended December 31, 2016 to $11,359.1 million for 
the year ended December 31, 2017, due principally to higher crude oil costs and higher sales volumes of products. Additionally, 
cost of products sold reflects a $108.7 million benefit that is attributable to a decrease in the lower of cost or market reserve for 
the year ended December 31, 2017, a $183.3 million decrease compared to $291.9 million for the same period of last year. The 
reserve at December 31, 2017 is based on market conditions and prices at that time. Additionally, we recorded a $30.5 million and 
$27.3 million RINs cost reduction during 2017 as a result of the reinstatement of previously utilized RINs following our Cheyenne 
Refinery and Woods Cross Refinery small refinery exemptions, respectively.

Gross Refinery Margins
Gross refinery margin per barrel sold increased 42% from $8.16 for the year ended December 31, 2016 to $11.56 for the year 
ended December 31, 2017. This was due to the effects of an increase in the average per barrel sold sales price, partially offset by 
increased crude oil and feedstock prices during the current year. Gross refinery margin does not include the non-cash effects of 
lower of cost or market inventory valuation adjustments, goodwill and asset impairment charges or 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 sale prices of products sold and cost of products purchased.

Operating Expenses
Operating  expenses,  exclusive  of  depreciation  and  amortization,  increased  27%  from  $1,018.8  million  for  the  year  ended 
December 31, 2016 to $1,294.2 million for the year ended December 31, 2017 due principally to $208.7 million in costs attributable 
to the operations of our Petro-Canada Lubricants business and higher purchased fuel costs compared to 2016. For the years ended 
December 31, 2017 and 2016, operating expenses include $137.6 million and $90.4 million, respectively, in costs attributable to 
HEP operations.

Selling, General and Administrative Expenses
Selling, general and administrative expenses increased 111% from $125.6 million for the year ended December 31, 2016 to $264.9 
million for the year ended December 31, 2017, due principally to $127.7 million in costs attributable to the operations of our Petro-
Canada Lubricants business and related acquisition and integration costs. Incremental direct acquisition and integration costs of 
our Petro-Canada Lubricants business totaled $27.9 million and $13.4 million for the years ended December 31, 2017 and 2016, 
respectively. For the years ended December 31, 2017 and 2016, selling, general and administrative expenses include $11.9 million
and $10.1 million, respectively, in costs attributable to HEP operations.

Depreciation and Amortization Expenses
Depreciation and amortization increased 13% from $363.0 million for the year ended December 31, 2016 to $409.9 million for 
the year ended December 31, 2017. This increase was due principally to $30.9 million in depreciation and amortization expenses 
attributable to the operations of our Petro-Canada Lubricants business and capitalized improvement projects and capitalized refinery 
turnaround costs. For the years ended December 31, 2017 and 2016, depreciation and amortization expenses include $77.7 million 
and $68.8 million, respectively, in costs attributable to HEP operations.

Goodwill and Asset Impairment
During  the  year  ended  December 31,  2017,  we  recorded  a  $19.2  million  long-lived  asset  impairment  charge  resulting  from 
management's plan to cease further expansion of our Woods Cross Refinery to add lubricants production compared to goodwill 
and long-lived asset impairment charges of $309.3 million and $344.8 million, respectively, for the year ended December 31, 2016
that related to our Cheyenne Refinery. See Note 10 “Goodwill” in the Notes to Consolidated Financial Statements for additional 
information on these impairments.

Interest Income
Interest income for the year ended December 31, 2017 was $3.7 million compared to $2.5 million for the year ended December 31, 
2016. This increase was due to higher interest rates received on cash balances during 2017.

Table of Content

Interest Expense
Interest  expense  was  $117.6  million  for  the  year  ended  December 31,  2017  compared  to  $72.2  million  for  the  year  ended 
December 31, 2016. This increase was due to interest attributable to higher debt levels during the current year relative to 2016. 
For the years ended December 31, 2017 and 2016, interest expense included $58.4 million and $52.6 million, respectively, in 
interest costs attributable to HEP operations.

Loss on Early Extinguishment of Debt
For the year ended December 31, 2017, a $12.2 million loss was recorded upon HEP's redemption of its $300 million aggregate 
principal amount of 6.5% senior notes maturing March 2020 at a cost of $309.8 million.

For the year ended December 31, 2016, we recognized an $8.7 million loss on the early retirement of a financing obligation, a 
component of outstanding debt, upon HEP's purchase of crude oil tanks from an affiliate of Plains. See Note 12 "Debt" in the 
Notes to Consolidated Financial Statements for additional information on this financing obligation.

Gain (Loss) on Foreign Currency Swap
During the years ended December 31, 2017 and 2016, we recorded a $24.5 million gain and a $6.5 million loss, respectively, on 
currency swap contracts that effectively fixed the conversion rate on $1.125 billion Canadian dollars (the PCLI purchase price), 
which were settled on February 1, 2017, in connection with the closing of the PCLI acquisition.

Gain on Foreign Currency Transactions
Remeasurement adjustments resulting from the conversion of the intercompany financing structure on our PCLI acquisition from 
local currencies to the U.S. dollar resulted in a $16.9 million gain for the year ended December 31, 2017.

Income Taxes
For the year ended December 31, 2017, we recorded a net income tax benefit of $12.4 million compared to an income tax expense 
of $19.4 million for the year ended December 31, 2016. Our effective tax rates, before consideration of earnings attributable to 
the noncontrolling interest, were (1.4)% and (11.3)% for the years ended December 31, 2017 and 2016, respectively. During the 
year ended December 31, 2017, we recorded a tax benefit of $307.1 million as a result of the Tax Cut and Jobs Act which was 
enacted on December 22, 2017. During the year ended December 31, 2016, we recorded a $309.3 million goodwill impairment 
charge, a significant driver of our $171.5 million loss before income taxes for the year ended December 31, 2016, that is not 
deductible for income tax purposes. 

Results of Operations – Year Ended December 31, 2016 Compared to Year Ended December 31, 2015 

Summary
Net loss attributable to HollyFrontier stockholders for the year ended December 31, 2016 was $260.5 million ($1.48 per basic and 
diluted share), a $1,000.6 million decrease compared to net income attributable to HollyFrontier stockholders of $740.1 million
($3.91 per basic and $3.90 per diluted share) for the year ended December 31, 2015. Net income decreased due principally to non-
cash goodwill and long-lived asset impairment charges of $309.3 million and $344.8 million, respectively, and a year-over-year 
decrease in refining margins and sales volumes, net of the effects of a year-over-year change in lower of cost or market inventory 
reserve adjustments. For the year ended December 31, 2016, lower of cost or market inventory reserve adjustments increased pre-
tax earnings by $291.9 million compared to a pre-tax earnings decrease of $227.0 million for the year ended December 31, 2015. 
Collectively, the impairment charges, net of the lower of cost or market valuation benefit, reduced 2016 pre-tax income by $362.1 
million. Refinery gross margins for the year ended December 31, 2016 decreased to $8.16 per barrel sold from $15.88 for the year 
ended December 31, 2015.

Sales and Other Revenues
Sales and other revenues decreased 20% from $13,237.9 million for the year ended December 31, 2015 to $10,535.7 million for 
the year ended December 31, 2016 due to a year-over-year decrease in sales prices and lower product sales volumes. Sales and 
other revenues for the years ended December 31, 2016 and 2015 include $68.9 million and $66.7 million, respectively, in HEP 
revenues attributable to pipeline and transportation services provided to unaffiliated parties.

Cost of Products Sold
Total cost of products sold decreased 19% from $10,466.2 million for the year ended December 31, 2015 to $8,474.0 million for 
the year ended December 31, 2016, due principally to lower crude oil costs and lower sales volumes of products. Additionally, 
this decrease reflects a $291.9 million benefit that is attributable to a reduction in the lower of cost or market reserve for the year 
ended December 31, 2016, a $518.9 million increase compared to a charge of $227.0 million for the year ended December 31, 
2015. The reserve at December 31, 2016 is based on market conditions and prices at that time.

Gross Refinery Margins
Gross refinery margin per barrel sold decreased 49% from $15.88 for the year ended December 31, 2015 to $8.16 for the year 
ended December 31, 2016. This was due to the effects of a decrease in the average per barrel sold sales price, partially offset by 
decreased crude oil and feedstock prices during the current year. Gross refinery margin does not include the non-cash effects of 
lower of cost or market inventory valuation adjustments, goodwill and asset impairment charges or 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,  decreased  4%  from  $1,060.4  million  for  the  year  ended 
December 31,  2015  to  $1,018.8  million  for  the  year  ended  December 31,  2016  due  principally  to  lower  natural  gas  fuel  and 
maintenance costs compared to 2015. For the years ended December 31, 2016 and 2015, operating expenses include $90.4 million
and $102.3 million, respectively, in costs attributable to HEP operations.

Selling, General and Administrative Expenses
Selling, general and administrative expenses increased 4% from $120.8 million for the year ended December 31, 2015 to $125.6 
million for the year ended December 31, 2016, due principally to pre-acquisition costs of PCLI. For the years ended December 31, 
2016 and 2015, general and administrative expenses include $10.1 million and $10.2 million, respectively, in costs attributable to 
HEP operations.

Depreciation and Amortization Expenses
Depreciation and amortization increased 5% from $346.2 million for the year ended December 31, 2015 to $363.0 million for the 
year ended December 31, 2016. This increase was due principally to depreciation and amortization attributable to capitalized 
improvement projects and capitalized refinery turnaround costs. For the years ended December 31, 2016 and 2015, depreciation 
and amortization expenses include $68.8 million and $61.7 million, respectively, in costs attributable to HEP operations.

Goodwill and Asset Impairment
During the year ended December 31, 2016, we recorded goodwill and long-lived asset impairment charges of $309.3 million and 
$344.8 million, respectively, that relate to our Cheyenne Refinery. See Note 10 “Goodwill” in the Notes to Consolidated Financial 
Statements for additional information on the Cheyenne impairment.

Interest Income
Interest income for the year ended December 31, 2016 was $2.5 million compared to $3.4 million for the year ended December 31, 
2015. This decrease was due to higher investment levels in marketable debt securities during 2015.

Interest Expense
Interest  expense  was  $72.2  million  for  the  year  ended  December 31,  2016  compared  to  $43.5  million  for  the  year  ended 
December 31, 2015. This increase was due to interest attributable to higher debt levels during 2016 relative to 2015. For the years 
ended December 31, 2016 and 2015, interest expense included $52.6 million and $36.9 million, respectively, in interest costs 
attributable to HEP operations.

Loss on Early Extinguishment of Debt
In March 2016, we recognized an $8.7 million loss on the early retirement of a financing obligation, a component of outstanding 
debt, upon HEP's purchase of crude oil tanks from an affiliate of Plains. See Note 12 “Debt” in the Notes to Consolidated Financial 
Statements for additional information on this financing obligation.

In June 2015, we recognized a $1.4 million early extinguishment loss on the redemption of our $150.0 million aggregate principal 
amount of 6.875% senior notes maturing November 2018. 

Income Taxes
For the year ended December 31, 2016, we recorded income tax expense of $19.4 million compared to $406.1 million for the year 
ended December 31, 2015. This decrease was due principally to a pre-tax loss during the year ended December 31, 2016 compared 
to  pre-tax  earnings  during  the  year  ended  2015.  Our  effective  tax  rates,  before  consideration  of  earnings  attributable  to  the 
noncontrolling interest, were (11.3)% and 33.6% for the years ended December 31, 2016 and 2015, respectively. For the year 
ended December 31, 2016. the effective tax rate reflects the effects of the $309.3 million goodwill impairment charge, a significant 
driver of our $171.5 million loss before income taxes for the year ended December 31, 2016, that is not deductible for income tax 
purposes.

LIQUIDITY AND CAPITAL RESOURCES

HollyFrontier Credit Agreement 
We  have  a  $1.35  billion  senior  unsecured  revolving  credit  facility  maturing  in  February  2022  (the  “HollyFrontier  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. During the year ended December 31, 2017, we received advances totaling 
$26.0 million and repaid $26.0 million under the HollyFrontier Credit Agreement. At December 31, 2017, we were in compliance 
with all covenants, had no outstanding borrowings and had outstanding letters of credit totaling $2.8 million under the HollyFrontier 
Credit Agreement. 

HEP Credit Agreement
HEP has a $1.4 billion senior secured revolving credit facility maturing in July 2022 (the “HEP Credit Agreement”) and is available 
to fund capital expenditures, investments, acquisitions, distribution payments, working capital and for general partnership purposes. 
It is also available to fund letters of credit up to a $50 million sub-limit and has a $300 million accordion. During the year ended 
December 31, 2017, HEP received advances totaling $969.0 million and repaid $510.0 million under the HEP Credit Agreement. 
At December 31, 2017, HEP was in compliance with all of its covenants, had outstanding borrowings of $1,012.0 million and no 
outstanding letters of credit under the HEP Credit Agreement.

HEP Senior Notes
In September 2017, HEP issued an additional $100 million in aggregate principal amount of 6.0% HEP senior notes maturing in 
August 2024 in a private placement. HEP used the net proceeds of $101.8 million to repay indebtedness under the HEP Credit 
Agreement.

In January 2017, HEP redeemed its $300 million aggregate principal amount of 6.50% senior notes maturing March 2020 at a 
redemption cost of $309.8 million, at which time HEP recognized a $12.2 million early extinguishment loss consisting of a $9.8 
million debt redemption premium and unamortized discount and financing costs of $2.4 million. HEP funded the redemption with 
borrowings under the HEP Credit Agreement.

See Note 12 "Debt" in the Notes to Consolidated Financial Statements for additional information on our debt instruments.

HEP Common Unit Continuous Offering Program
On May 10, 2016, HEP established a continuous offering program under which HEP may issue and sell common units from time 
to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million. During the year ended 
December 31, 2017, HEP issued 1,538,452 common units under this program, providing $52.1 million in net proceeds. In connection 
with this program and to maintain our then economic 2% general partner interest in HEP, we made capital contributions totaling 
$1.1 million during the year ended December 31, 2017. As of December 31, 2017, HEP has issued 2,241,907 common units with 
an aggregate gross sales amount of $77.1 million.

HEP intends to use the net proceeds for general partnership purposes, which may include funding working capital, repayment of 
debt, acquisitions and capital expenditures. Amounts repaid under HEP’s credit facility may be reborrowed from time to time.

HEP Private Placement Agreement
On January 25, 2018, HEP entered into a common unit purchase agreement in which certain purchasers agreed to purchase in a 
private placement 3,700,000 HEP common units, representing limited partner interests, at a price of $29.73 per common unit. The 
private placement closed on February 6, 2018, at which time HEP received proceeds of approximately $110.0 million, which were 
used to repay indebtedness under the HEP Credit Agreement. After this common unit issuance, our limited partner interest in HEP 
is 57%.

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.

Table of Content

As of December 31, 2017, our cash and cash equivalents totaled $630.8 million. 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.

On October 29, 2016, our wholly-owned subsidiary, 9952110 Canada Inc., entered into a share purchase agreement with Suncor 
to acquire 100% of the outstanding capital stock of PCLI. The acquisition closed on February 1, 2017. Cash consideration paid 
was $862.1 million, or $1.125 billion in Canadian dollars. 

In May 2015, our Board of Directors approved a $1 billion share repurchase program, which replaced all existing share repurchase 
programs, authorizing us to repurchase common stock in the open market or through privately negotiated transactions. The timing 
and amount of stock repurchases will depend on market conditions and corporate, regulatory and other relevant considerations. 
This program may be discontinued at any time by our Board of Directors. As of  December 31, 2017, we had remaining authorization 
to repurchase up to $178.8 million under this stock repurchase program. 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 $79.8 million for the year ended December 31, 2017. Net cash used for investing and financing 
activities of $959.7 million and $72.6 million, respectively, exceeded net cash provided by operating activities of $951.4 million. 
Working capital decreased by $127.7 million during the year ended December 31, 2017.

Cash Flows – Operating Activities

Year Ended December 31, 2017 Compared to Year Ended December 31, 2016 
Net cash flows provided by operating activities were $951.4 million for the year ended December 31, 2017 compared to $606.9 
million for the year ended December 31, 2016, an increase of $344.4 million. Net income for the year ended December 31, 2017 
was $881.2 million, an increase of $1,072.2 million compared to net loss of $190.9 million for the year ended December 31, 2016. 
Non-cash adjustments to net income consisting of depreciation and amortization, goodwill and asset impairment, lower of cost or 
market inventory valuation adjustment, earnings of equity method investments, inclusive of distributions, gain on equity company 
acquisition, gain or loss on sale of assets, loss on extinguishment of debt, deferred income taxes, equity-based compensation

Cash Flows – Investing Activities and Planned Capital Expenditures

Year Ended December 31, 2017 Compared to Year Ended December 31, 2016 
Net cash flows used for investing activities were $959.7 million for the year ended December 31, 2017 compared to $801.6 million
for the year ended December 31, 2016, an increase of $158.1 million. Current year investing activities reflect a net cash outflow 
of $870.6 million upon the acquisition of PCLI. Cash expenditures for properties, plants and equipment for 2017 decreased to 
$272.3 million from $479.8 million for the same period in 2016. These include HEP capital expenditures of $44.8 million and 
$107.6 million for the years ended December 31, 2017 and 2016, respectively. In addition, in 2017, HEP purchased the remaining 
interests in SLC Pipeline and Frontier Pipeline for $245.4 million. In 2016, HEP purchased a 50% interest in Cheyenne Pipeline 
for $42.6 million. We received proceeds of $1.4 million and $0.8 million from the sale of assets during the years ended December 31, 
2017 and 2016, respectively. For the years ended December 31, 2017 and 2016, we invested $41.6 million and $546.6 million, 
respectively, in marketable securities and received proceeds of $465.7 million and $266.6 million, respectively, from the sale or 
maturity of marketable securities. 

Year Ended December 31, 2016 Compared to Year Ended December 31, 2015 
Net cash flows used for investing activities were $801.6 million for the year ended December 31, 2016 compared to $381.7 million
for the year ended December 31, 2015, an increase of $419.8 million. Cash expenditures for properties, plants and equipment for 
2016 decreased to $479.8 million from $676.2 million for the same period in 2015. These include HEP capital expenditures of 
$107.6 million and $193.1 million for the years ended December 31, 2016 and 2015, respectively. In addition, in 2016, :HEP 
purchased a 50% interest in Cheyenne Pipeline for $42.6 million, and in 2015, a 50% interest in Frontier Pipeline for $55.0 million. 
We received proceeds of $0.8 million and $19.3 million from the sale of assets during the years ended December 31, 2016 and 
2015, respectively. For the years ended December 31, 2016 and 2015, we invested $546.6 million and $509.3 million, respectively, 
in marketable securities and received proceeds of $266.6 million and $839.5 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. During 2018, 
we expect to spend approximately $425.0 million to $500.0 million in cash for capital projects and refinery turnarounds appropriated 
in 2018 and prior years. Refinery turnaround spending is amortized over the useful life of the turnaround. Our expected capital 
and turnaround cash spending for 2018 is as follows:

The  refining  industry  is  capital  intensive  and  requires  on-going  investments  to  sustain  our  refining  operations. This  includes 
replacement of, or rebuilding, refinery units and components that extend the useful life. We also invest in projects that improve 
operational reliability and profitability via enhancements that improve refinery processing capabilities as well as production yield 
and flexibility. Our capital expenditures also include projects related to environmental, health and safety compliance and include 
initiatives as a result of federal and state mandates.

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, Tier 3 which mandates a reduction in the sulfur 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.

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 in 
excess of a year, 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 2018 HEP capital budget is comprised of 
$8.0 million for maintenance capital expenditures and $40.0 million for expansion capital expenditures. HEP expects the majority 
of the expansion capital budget to be invested in refined product pipeline expansions, crude system enhancements, new storage 
tanks, and enhanced blending capabilities at our racks.

borrowings under the HEP Credit Agreement. The HEP Credit Agreement expires in 2022.

(5)  Interest payments consist of interest on the 6% HEP senior notes and interest on long-term debt under the HEP Credit Agreement. 

Interest on the HEP Credit Agreement debt is based on the weighted average rate of 3.73% at December 31, 2017.

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.

Table of Content

Inventory Valuation 
Inventories related to our refining operations are stated at the lower of cost, using the LIFO method for crude oil and unfinished 
and finished refined products, or market. 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. At December 31, 2017 and 2016, market values had fallen below historical 
LIFO inventory costs and, as a result, we recorded lower of cost or market inventory valuation reserves of $223.8 million and 
$332.5 million, respectively.

At December 31, 2017, our lower of cost or market inventory valuation reserve was $223.8 million. This amount, or a portion 
thereof, is subject to reversal as a reduction to cost of products sold in subsequent periods as inventories giving rise to the reserve 
are sold, and a new reserve is established. Such a reduction to cost of products sold could be significant if inventory values return 
to historical cost price levels. Additionally, further decreases in overall inventory values could result in additional charges to cost 
of products sold should the lower of cost or market inventory valuation reserve be increased.

Goodwill and Long-lived Assets
As of December 31, 2017, our goodwill balance was $2.2 billion, with goodwill assigned to our Refining, Lubricants and Specialty 
Products and HEP segments of $1.7 billion, $0.2 billion and $0.3 billion, respectively. 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 an event occurs or circumstances change that would more likely than not reduce the fair 
value of a reporting unit below its carrying amount. Our goodwill impairment testing first entails a comparison of our reporting 
unit fair values relative to their respective carrying values. If carrying value exceeds fair value for a reporting unit, we measure 
goodwill impairment as the excess of the carrying amount of reporting unit goodwill over the implied fair value of that goodwill 
based on estimates of the fair value of all assets and liabilities in the reporting unit.

Our long-lived assets principally consist of our refining assets that are organized as refining asset groups and the assets of our 
Lubricants and Specialty Products business. The refinery asset groups also constitute our individual refinery reporting units that 
are used for testing and measuring goodwill impairments. Our long-lived assets are evaluated for 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 measured, if any, is equal to the amount by which the asset group’s carrying 
value exceeds its fair value.

We performed our annual goodwill impairment testing at July 1, 2017 and determined that the fair value of our El Dorado reporting 
unit exceeded its carrying value by approximately 10%. A reasonable expectation exists that future deterioration in gross margins 
could result in an impairment of goodwill and the long-lived assets of the El Dorado reporting unit at some point in the future and 
such impairment charges could be material. Additionally, qualitative testing indicated no impairment of goodwill attributable to 
our other reporting units.

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.

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;

Table of Content

• 
• 
• 

costs of crude oil and related grade differentials;
prices of refined products; and
our refining margins.

As of December 31, 2017, we have the following notional contract volumes related to all outstanding derivative contracts used 
to mitigate commodity price risk:

Interest Rate Risk Management
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 this debt as of December 31, 2017 is presented below:

For the variable rate HEP Credit Agreement, changes in interest rates would affect cash flows, but not the fair value. At December 31, 
2017, outstanding borrowings under the HEP Credit Agreement were $1,012.0 million. A hypothetical 10% change in interest 
rates applicable to the HEP Credit Agreement would not materially affect cash flows. 

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.

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 (loss) 
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 is 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.

Set forth below is our calculation of EBITDA.

and 2015, respectively.

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 produced barrel sold 
is total refining segment revenues less total refining segment cost of products sold, exclusive of lower of cost or market inventory 
valuation adjustments, divided by sales volumes of produced refined products sold. Net operating margin per barrel sold is the 
difference between refinery gross margin and refinery operating expenses per barrel sold. These two margins do not include the 
non-cash effects of lower of cost or market inventory valuation adjustments, goodwill and asset impairment charges 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.

Below are reconciliations to our consolidated statements of income for refinery net operating and gross margin and operating expenses, 
in each case averaged per produced barrel sold. Due to rounding of reported numbers, some amounts may not calculate exactly.

Item 8.  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.

On February 1, 2017, we completed the acquisition of Petro-Canada Lubricants Inc. (“PCLI”). We are in the process of integrating 
operations of PCLI and affiliated entities related to this acquired business (“PCLI business”), including internal controls over 
financial reporting and, therefore, management's evaluation and conclusion as to the effectiveness of our internal control over 
financial reporting as of the end of the period covered by this Annual Report on Form 10-K excludes any evaluation of the internal 
control over financial reporting of the PCLI business. The PCLI business accounted for 12% of the Company's total assets and 
8% of total revenues of the Company as of and for the year ended December 31, 2017.

Management assessed the Company's internal control over financial reporting as of December 31, 2017 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, 2017, 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, 2017. That report appears on page 54.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Stockholders and the Board of Directors of HollyFrontier Corporation

Opinion on Internal Control over Financial Reporting

We have audited HollyFrontier Corporation’s internal control over financial reporting as of December 31, 2017, 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). In our opinion, HollyFrontier Corporation (the Company) maintained, in all 
material respects, effective internal control over financial reporting as of December 31, 2017, based on the COSO criteria.

As indicated in the accompanying Management’s Report on its Assessment of the Company’s Internal Control Over Financial 
Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not 
include the internal controls of the PCLI business acquired on February 1, 2017, which is included in the 2017 consolidated financial 
statements of the Company and constituted 12% of total assets as of December 31, 2017 and 8% of revenues for the year then 
ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal 
control over financial reporting of the PCLI business.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company Accounting  Oversight  Board  (United  States) 
(PCAOB), the consolidated balance sheets of the Company as of December 31, 2017 and 2016, the related consolidated statements 
of income, comprehensive income, cash flows, and equity for each of the three years in the period ended December 31, 2017, and 
the related notes of the Company and our report dated February 21, 2018 expressed an unqualified opinion thereon.

Basis for Opinion 

The Company’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 are a public accounting firm registered with the PCAOB 
and  are  required  to  be  independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. 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. 

Definition and Limitations of Internal Control Over Financial Reporting 

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. 

54

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of HollyFrontier Corporation

Opinion on the Financial Statements

We have audited the  accompanying consolidated balance sheets of HollyFrontier Corporation (the Company) as of December 31, 
2017 and 2016, the related consolidated statements of income, comprehensive income, cash flows, and equity for each of the three 
years in the period ended December 31, 2017, and the related notes (collectively referred to as the “financial statements”). In our 
opinion, the financial statements present fairly, in all material respects, the financial position of the Company at December 31, 
2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 
2017, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company's internal control over financial reporting as of December 31, 2017, 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 21, 2018 expressed an unqualified opinion thereon.

Basis for Opinion 

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error 
or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether 
due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, 
evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting 
principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial 
statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ Ernst & Young LLP  

We have served as the Company’s auditor since 1977.

HOLLYFRONTIER CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1:  Description of Business and Summary of Significant Accounting Policies

Description  of  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. In addition, we own and operate a 
lubricant production facility with retail and wholesale marketing of its products through a global sales network with locations in 
Canada, United States, Europe and China. As of December 31, 2017, 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 Petro-Canada Lubricants Inc. (“PCLI”) located in Mississauga, Ontario which produces base oils 
and other specialized lubricant products;

owned  and  operated  HollyFrontier Asphalt  Company  (“HFC Asphalt”)  which  operates  various  asphalt  terminals  in 
Arizona, New Mexico and Oklahoma; and

owned a 59% limited partner interest and a non-economic general partner interest in HEP, a variable interest entity (“VIE”).

On October 29, 2016, our wholly-owned subsidiary, 9952110 Canada Inc., entered into a share purchase agreement with Suncor 
Energy Inc. (“Suncor”) to acquire 100% of the outstanding capital stock of PCLI. The acquisition closed on February 1, 2017. See 
Note 2 for additional information.

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 as HEP's primary beneficiary, 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.

63

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 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 $3.6 million and $2.3 million
at December 31, 2017 and 2016, respectively.

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 related to our refining operations are stated at the lower of cost, using the last-in, first-out (“LIFO”) 
method for crude oil and unfinished and finished refined products, 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.

Inventories of our Petro-Canada Lubricants business are stated at the lower of cost, using the first-in, first-out (“FIFO”) method, 
or net realizable value.

Inventories consisting of process chemicals, materials and maintenance supplies and RINs are stated at the lower of weighted-
average cost or net realizable value.

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 13 for additional information.

Properties, plants and equipment:  Properties, plants and equipment are stated at cost. Depreciation is provided by the straight-
line method over the estimated useful lives of the assets, primarily 15 to 32 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.

64

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 $24.8 million and $22.1 million at December 31, 2017 and 2016, respectively, which are 
included in “Other long-term liabilities” in our consolidated balance sheets. Accretion expense was insignificant for the years 
ended December 31, 2017, 2016 and 2015. 

Intangibles, Goodwill and long-lived assets:  Intangible assets are assets (other than financial assets) that lack physical substance, 
and goodwill represents the excess of the cost of an acquired entity over the fair value of the assets acquired and liabilities assumed. 
Goodwill acquired in a business combination and intangibles with indefinite useful lives are not amortized, whereas 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 
goodwill impairment testing first entails a comparison of our reporting unit fair values relative to their respective carrying values. 
If carrying value exceeds fair value for a reporting unit, we measure goodwill impairment as the excess of the carrying amount of 
reporting unit goodwill over the implied fair value of that goodwill based on estimates of the fair value of all assets and liabilities 
in the reporting unit. 

Our long-lived assets principally consist of our refining assets that are organized as refining asset groups and our lubricants and 
specialty products business. The refinery asset groups also constitute our individual refinery reporting units that are used for testing 
and measuring goodwill impairments. Our long-lived assets are evaluated for 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 measured, if any, is equal to the amount by which the asset group’s carrying value exceeds 
its fair value.

See  Note  10  for  information  regarding  goodwill  and  long-lived  asset  impairment  charges  recorded  during  the  years  ended 
December 31, 2017 and 2016. 

Upon  our  acquisition  of  PCLI,  we  recognized  intangibles,  including  trademarks,  patents,  technical  know-how  and  customer 
relationships, totaling $102.1 million that are being amortized on a straight-line basis over periods ranging from 10 to 20 years. 
At December 31, 2017, the balance of these intangibles was $100.0 million, and is presented net of accumulated amortization of 
$5.9 million in “Intangibles and other” in our consolidated balance sheets.

Our  consolidated  HEP  assets  include  intangible  assets  consisting  of  third-party  transportation  agreements  and  customer 
relationships. These intangible assets are amortized on a straight-line basis over periods ranging from 10 to 30 years. Amortization 
expense  was  $2.6  million  and  $2.0  million  for  the  years  ended  December 31,  2017  and  2016,  respectively,  and  expected  to 
approximate $8.0 million annually over the next five years. The balances of these intangible assets were $95.2 million and $36.5 
million at December 31, 2017, and 2016, respectively, and are presented net of accumulated amortization of $26.3 million and 
$23.7 million, respectively, in “Intangibles and other” in our consolidated balance sheets. 

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% or a controlling interest with respect to VIE’s, and use the equity method of accounting for investments 
in which we have a noncontrolling interest, yet have significant influence over the entity. 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 50% interest in Osage Pipe Line Company, LLC, the owner of a pipeline running from Cushing, Oklahoma to El Dorado, 
Kansas (the “Osage Pipeline”) and a 50% interest in Cheyenne Pipeline, LLC, the owner of a pipeline running from Fort Laramie, 
Wyoming to Cheyenne, Wyoming (the “Cheyenne Pipeline”), that are accounted for using the equity method of accounting. As 
of December 31, 2017, HEP's underlying equity and recorded investment balances in the joint ventures are $39.3 million and $85.3 
million, respectively. The differences are being amortized as adjustments to HEP's pro-rata share of earnings in the joint ventures. 

65

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

Our Petro-Canada Lubricants business has sales agreements with marketers and distributors that provide certain rights of return 
or provisions for the repurchase of products previously sold to them. Under these agreements with Canadian marketers, revenues 
and cost of revenues are deferred until the products have been sold to end customers, and for sales to U.S. distributors, revenues 
are recognized when products are shipped to the distributors, net of allowances for returns that are expected to be repurchased 
from the distributors. In both cases, repurchased products are subsequently sold directly to end customers. 

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. 
Selling, 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  $112.9  million,  $110.6  million  and  $107.8  million  for  the  years  ended 
December 31, 2017, 2016 and 2015, 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. We have ongoing investigations of environmental 
matters at various locations and routinely assess our recorded environmental obligations, if any, with respect to such matters. 
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.

Foreign Currency Translation: The functional currency of PCLI and its affiliated non-U.S. Petro-Canada Lubricants entities 
includes the Canadian dollar, the euro and Chinese renminbi. Balance sheet accounts are translated into U.S. dollars using exchange 
rates in effect as of the balance sheet date. Revenue and expense accounts are translated using the weighted-average exchange 
rates during the period presented. Foreign currency translation adjustments are recorded as a component of accumulated other 
comprehensive income.

In connection with our PCLI acquisition on February 1, 2017, we issued intercompany notes to initially fund certain of our foreign 
businesses. Remeasurement adjustments resulting from the conversion of such intercompany financing amounts to functional 
currencies are recorded as gains and losses as a component of other income (expense) in the income statement. Such adjustments 
are not recorded to the Lubricants and Specialty Products segment operations, but to corporate and other. See Note 20 for additional 
information on our segments.

HOLLYFRONTIER CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 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.

Inventory Repurchase Obligations: We periodically enter into same-party sell / buy transactions, whereby we sell certain refined 
product inventory and subsequently repurchase the inventory in order to facilitate delivery to certain locations. Such sell / buy 
transactions are accounted for as inventory repurchase obligations under which proceeds received under the initial sell is recognized 
as an inventory repurchase obligation that is subsequently reversed when the inventory is repurchased. For the years ended December 
31, 2017, 2016 and 2015, we received proceeds of $47.4 million, $57.0 million and $115.4 million and subsequently repaid $49.8 
million, $58.0 million and $115.3 million, respectively, under these sell / buy transactions.

New Accounting Pronouncements

Hedge Accounting
In August 2017, Accounting Standard Update (“ASU”) 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting 
for Hedging Activities,” was issued amending hedge accounting recognition and presentation requirements, including elimination 
of  the  requirement  to  separately  measure  and  report  hedge  ineffectiveness,  and  eases  certain  documentation  and  assessment 
requirements. This standard has an effective date of January 1, 2019. We do not expect adoption of this standard to have a material 
impact on our financial condition, results of operations or cash flows.

Post-retirement Benefit Cost
In March 2017, ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-retirement Benefit 
Cost,” was issued amending current GAAP related to the income statement presentation of the components of net periodic post-
retirement cost (credit). This standard has an effective date of January 1, 2018. We do not expect adoption of this standard to have 
a material impact on our financial condition, results of operations or cash flows.

Share-Based Compensation
In March 2016, ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting,” was issued which simplifies the 
accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures and statutory 
tax withholding requirements, as well as classification in the statement of cash flows. We adopted this standard effective January 
1, 2017 on a prospective basis with the excess tax expense from stock-based compensation recognized as a discrete item in our 
provision for income taxes. Excess tax expense for the year ended December 31, 2017 totaled $0.7 million. The new standard also 
requires that employee taxes paid when an employer withholds shares for tax-withholding purposes be reported as financing 
activities in the statement of cash flows on a retrospective basis. Previously, this activity was included in operating activities. The 
impact of this change for the years ended December 31, 2017, 2016 and 2015 was $15.9 million, $4.7 million and $6.2 million, 
respectively. Finally, consistent with our existing policy, we have elected to account for forfeitures on an estimated basis.

Leases
In February 2016, ASU 2016-02, “Leases,” was issued requiring leases to be measured and recognized as a lease liability, with a 
corresponding right-of-use asset on the balance sheet. This standard has an effective date of January 1, 2019, and we are evaluating 
the impact of this standard. In preparing for adoption, we have identified, reviewed and evaluated contracts containing lease and 
embedded lease arrangements. Additionally, we have acquired software and are implementing systems to facilitate lease capture 
and related accounting treatment.

Inventories Measurement
In  July  2015, ASU  2015-11,  “Inventory  -  Simplifying  the  Measurement  of  Inventory,”  was  issued  requiring  measurement  of 
inventories, other than inventories accounted for using the LIFO method, to be measured at the lower of cost or net realizable 
value. Net realizable value is defined as the estimated selling price in the ordinary course of business less reasonable, predictable 
cost of completion, disposal and transportation. We adopted this standard effective January 1, 2017 for our affected inventories, 
which is primarily the inventory of our Petro-Canada Lubricants business that is valued on a FIFO basis. Adoption had no material 
effect on our financial condition, results of operations or cash flows.

Revenue Recognition
In May 2014, 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 has an effective date of January 1, 2018, and we anticipate using the modified retrospective implementation 
method, whereby a cumulative effect adjustment is recorded to retained earnings as of the date of initial application. In preparing 
for adoption, we have evaluated the terms, conditions and performance obligations under our existing contracts with customers. 
Furthermore, we have implemented policies to comply with this new standard, which we do not anticipate will have a material 
impact on our financial condition, results of operations or cash flows.

NOTE 2: 

PCLI Acquisition

On October 29, 2016, our wholly-owned subsidiary, 9952110 Canada Inc., entered into a share purchase agreement with Suncor 
to acquire 100% of the outstanding capital stock of PCLI. The acquisition closed on February 1, 2017. Cash consideration paid 
was $862.1 million, or $1.125 billion in Canadian dollars. PCLI is located in Mississauga, Ontario, Canada and is a producer of 
lubricant products such as base oils, white oils, specialty products and finished lubricants. The operations of our Petro-Canada 
Lubricants business also include marketing of these products to both retail and wholesale outlets through a global sales network 
with locations in Canada, the United States, Europe and China.

Aggregate consideration totaled $906.7 million and consists of $862.1 million in cash paid to Suncor at acquisition, a closing date 
working capital settlement of $30.6 million that was paid to Suncor in the second quarter of 2017, an accrued payable in the amount 
of $7.4 million, and $6.6 million representing a portion of the fair value of replacement restricted stock unit awards issued to PCLI 
employees that relate to pre-acquisition services.

This transaction is accounted for as a business combination using the acquisition method of accounting, with the purchase price 
allocated to the fair value of the acquired PCLI assets and liabilities as of the February 1 acquisition date, with the excess purchase 
price recorded as goodwill assigned to our Lubricants and Specialty Products segment. This goodwill is not deductible for income 
tax purposes.

Our consolidated financial and operating results reflect the operations of our Petro-Canada Lubricants business beginning February 
1, 2017. Our results of operations for the year ended December 31, 2017 included revenues and income before income taxes of 
$1,125.3 million and $71.8 million, respectively, related to these operations.

As of December 31, 2017, we have incurred $27.9 million in incremental direct acquisition and integration costs that principally 
relate to legal, advisory and other professional fees and are presented as selling, general and administrative expenses.

NOTE 3:  Holly Energy Partners

HEP is a publicly held master limited partnership that owns and operates logistic assets consisting of petroleum product and crude 
oil pipelines, terminals, tankage, loading rack facilities and refinery processing units that principally support our refining and 
marketing operations in the Mid-Continent, Southwest and Rocky Mountain regions of the United States and Delek’s refinery in 
Big Spring, Texas. Additionally, HEP owns a 75% interest in UNEV Pipeline, LLC (“UNEV”), the owner of pipeline running from 
Woods Cross, Utah to Las Vegas, Nevada (the “UNEV Pipeline”) and associated product terminals, and a 50% ownership interest 
in each of the Osage Pipeline and the Cheyenne Pipeline.

At December 31, 2017, we owned a 59% limited partner interest and a non-economic general partner interest in HEP. 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 as HEP's primary beneficiary, we consolidate HEP.

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, 2017. 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. HEP’s creditors have no recourse 
to our assets. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries. See Note 12 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.

SLC Pipeline and Frontier Pipeline
On October 31, 2017, HEP acquired the remaining 75% interest in SLC Pipeline LLC, the owner of a pipeline that serves refineries 
in the Salt Lake City, Utah area (the “SLC Pipeline”), and the remaining 50% interest in Frontier Aspen LLC, the owner of a 
pipeline running from Wyoming to Frontier Station, Utah (the “Frontier Pipeline”), from subsidiaries of Plains All American 
Pipeline, L.P. (“Plains”) for cash consideration of $250.0 million. 

These acquisitions were accounted for as a business combination achieved in stages. HEP’s preexisting equity method investments 
in SLC Pipeline and Frontier Aspen were remeasured at an acquisition date fair value of $112.0 million, since HEP acquired a 
controlling interest, and a gain was recognized on the remeasurement of $36.3 million. The fair value of HEP's preexisting equity 
method investments in SLC Pipeline and Frontier Aspen was estimated using Level 3 inputs under the income method for these 
entities, adjusted for lack of control and marketability.

The total consideration of $362.0 million, consisting of cash consideration of $250.0 million and the fair value of HEP's preexisting 
equity method investments in SLC Pipeline and Frontier Aspen of $112.0 million, was allocated to the acquisition date fair value 
of assets and liabilities acquired as of the October 31, 2017 acquisition date, with the excess purchase price recorded as goodwill. 
The fair values are preliminary, and therefore, may change once all needed information has become available and valuations are 
complete.

Woods Cross Assets
On October 3, 2016, HEP acquired from us all the membership interests of Woods Cross Operating LLC, which owns the crude 
unit, FCCU and polymerization unit of the first phase of our Woods Cross Refinery expansion project that was completed in the 
second quarter of 2016, for cash consideration of approximately $278.0 million.

In  connection  with  this  transaction,  we  entered  into  15-year  tolling  agreements  containing  minimum  quarterly  throughput 
commitments that provide minimum annualized payments to HEP of $56.7 million.

Cheyenne Pipeline
On June 3, 2016, HEP acquired a 50% interest in Cheyenne Pipeline LLC, owner of the Cheyenne Pipeline, in exchange for a 
contribution of $42.6 million in cash to Cheyenne Pipeline LLC. Cheyenne Pipeline will continue to be operated by an affiliate 
of Plains, which owns the remaining 50% interest. The 87-mile crude oil pipeline runs from Fort Laramie, Wyoming to Cheyenne, 
Wyoming and has an 80,000 BPD capacity.

Tulsa Tanks
On March 31, 2016, HEP acquired crude oil tanks located at our Tulsa Refineries from Plains for $39.5 million. Previously in 
2009, we sold these tanks to Plains and leased them back, and due to our continuing interest in the tanks, we accounted for the 
transaction as a financing arrangement. Accordingly, the tanks remained on our balance sheet and were depreciated for accounting 
purposes, and the proceeds received from Plains were recorded as a financing obligation and presented as a component of outstanding 
debt. 

In accounting for  HEP’s  March 2016 purchase from Plains, the amount paid was recorded against our outstanding financing 
obligation balance of $30.8 million, with the excess $8.7 million resulting in a loss on early extinguishment of debt.

Magellan Asset Exchange
On February 22, 2016, we obtained a 50% membership interest in Osage Pipe Line Company, LLC (“Osage”) in exchange for a 
20-year terminalling services agreement, whereby, a subsidiary of Magellan Midstream Partners (“Magellan Midstream”) will 
provide terminalling services for all of our products originating in Artesia, New Mexico that require terminalling in or through El 
Paso, Texas. Under the agreement, we will be charged tariffs based on the volumes of refined product processed. Osage is the 
owner of the Osage Pipeline, a 135-mile pipeline that transports crude oil from Cushing, Oklahoma to our El Dorado Refinery in 
Kansas and also has a connection to the Jayhawk pipeline that services the CHS refinery in McPherson, Kansas. This exchange 
was accounted for at fair value, whereby the 50% membership interest in the Osage Pipeline was recorded at fair value and an 
offsetting residual deferred credit in the amount of $38.9 million was recorded, which will be amortized to cost of products sold 
over the 20-year service period. No gain or loss was recorded for this exchange.

Also on February 22, 2016, we contributed the 50% membership interest in Osage to HEP, and in exchange received HEP's El 
Paso terminal. Pursuant to this exchange, HEP agreed to build two connections to Magellan Midstream's El Paso terminal. In 
addition, HEP agreed to become the operator of the Osage Pipeline. This exchange was accounted for at carry-over basis with no 
resulting gain or loss.

El Dorado Asset Transaction
On November 1, 2015, HEP acquired from us newly constructed naphtha fractionation and hydrogen generation units at our El 
Dorado Refinery for cash consideration of $62.0 million. In connection with this transaction, we entered into 15-year tolling 
agreements containing minimum quarterly throughput commitments that provide minimum annualized payments to HEP of $15.1 
million.

Frontier Pipeline Transaction
On August 31, 2015, HEP purchased a 50% interest in Frontier Aspen LLC (previously known as Frontier Pipeline Company), 
owner of the Frontier Pipeline, from an affiliate of Enbridge, Inc. for $55.0 million. The 289-mile crude oil pipeline runs from 
Casper, Wyoming to Frontier Station, Utah, has a 72,000 BPD capacity and supplies Canadian and Rocky Mountain crudes to Salt 
Lake City area refiners through a connection to the SLC Pipeline. As noted above, HEP acquired the remaining 50% interest on 
October 31, 2017.

Transportation Agreements
HEP serves our refineries under long-term pipeline, terminal and tankage throughput agreements and refinery processing tolling 
agreements expiring from 2020 through 2036. Under these agreements, we pay HEP fees to transport, store and process throughput 
volumes of refined products, crude oil and feedstocks on HEP's pipelines, terminals, tankage, loading rack facilities and refinery 
processing units 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, 2017, these 
agreements result in minimum annualized payments to HEP of $324.5 million.

Our transactions with HEP and fees paid under our transportation agreements with HEP and UNEV are eliminated and have no 
impact on our consolidated financial statements. 

Incentive Distribution Rights Simplification Agreement
On October 31, 2017, we closed on an equity restructuring transaction with HEP pursuant to which our incentive distribution rights 
were canceled and our 2% general partner interest in HEP was converted into a non-economic general partner interest in HEP. In 
consideration, we received 37,250,000 HEP common units. In addition, we agreed to waive $2.5 million of limited partner cash 
distributions for each of twelve consecutive quarters beginning with the first quarter the units issued were eligible to receive 
distributions as consideration.

HEP Private Placement Agreements
On January 25, 2018, HEP entered into a common unit purchase agreement in which certain purchasers agreed to purchase in a 
private placement 3,700,000 HEP common units, representing limited partner interests, at a price of $29.73 per common unit. The 
private placement closed on February 6, 2018, at which time HEP received proceeds of approximately $110.0 million, which were 
used to repay indebtedness under the HEP Credit Agreement. After this common unit issuance, our limited partner interest in HEP 
is 57%.

On October 3, 2016, HEP closed on a common unit purchase agreement in which certain purchasers agreed to purchase in a private 
placement 3,420,000 HEP common units, representing limited partnership interests, at a price of $30.18 per common unit. HEP 
received proceeds of approximately $103.0 million, which were used to finance a portion of the Woods Cross assets acquisition. 
In connection with this private placement and to maintain our then economic 2% general partner interest in HEP, we made capital 
contributions totaling $2.1 million to HEP in October 2016.

HEP Common Unit Continuous Offering Program
On May 10, 2016, HEP established a continuous offering program under which HEP may issue and sell common units from time 
to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million. During the year ended 
December 31, 2017, HEP issued 1,538,452 common units under this program, providing $52.1 million in net proceeds. In connection 
with this program and to maintain our then economic 2% general partner interest in HEP, we made capital contributions totaling 
$1.1 million during the year ended December 31, 2017. As of December 31, 2017, HEP has issued 2,241,907 common units with 
an aggregate gross sales amount of $77.1 million.

HEP intends to use the net proceeds for general partnership purposes, which may include funding working capital, repayment of 
debt, acquisitions and capital expenditures. Amounts repaid under HEP’s credit facility may be reborrowed from time to time.

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 reallocate HEP's equity among its unitholders.

NOTE 4: 

Fair Value Measurements

Our financial instruments measured at fair value on a recurring basis consist of investments in marketable securities, derivative 
instruments and RINs credit obligations. 

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.

71

HOLLYFRONTIER CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Continued

• 

• 

(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 of  marketable securities, derivative instruments and RINs credit obligations at December 31, 2017 and 
December 31, 2016 were as follows:

Level 2 Financial Instruments
Investments in marketable securities, derivative instruments consisting of commodity price swaps and forward sales and purchase 
contracts  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. RINs credit obligations are valued based on current market 
RINs prices. The fair value of the marketable securities is based on values provided by a third party, which were derived using 
market quotes for similar type instruments, a Level 2 input. 

Level 3 Financial Instruments
We at times have commodity price swap and forward contracts that relate to forecasted sales and purchases of commodities for 
which quoted forward market prices are not readily available. The forward rate used to value these price swaps and forward sales 
and purchase contracts are derived using a projected forward rate using quoted market rates for similar products, adjusted for 
regional pricing and grade differentials, a Level 3 input.

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, 2017 and 2016:

NOTE 5:  Earnings Per Share

Basic earnings per share is calculated as net income (loss) attributable to HollyFrontier stockholders divided by the average number 
of shares of common stock outstanding. Diluted earnings per share assumes, when dilutive, the issuance of the net incremental 
shares from restricted shares and performance share units. The following is a reconciliation of the denominators of the basic and 
diluted per share computations for net income (loss) attributable to HollyFrontier stockholders:

Stock-Based Compensation

As  of  December 31,  2017,  we  have  two  principal  share-based  compensation  plans  (collectively,  the  “Long-Term  Incentive 
Compensation Plan”). 

The compensation cost charged against income for these plans was $39.8 million, $22.8 million and $26.9 million for the years 
ended December 31, 2017, 2016 and 2015, 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 $2.5 million, $2.7 
million and $3.5 million for the years ended December 31, 2017, 2016 and 2015, respectively.

Restricted Stock and Restricted Stock Units
Under our Long-Term Incentive Compensation Plan, we grant certain officers and other key employees restricted stock unit awards 
with awards generally vesting over a period of two to three years. We previously granted restricted stock to certain officers and 
key employees with awards vesting over a period of three years. Certain restricted stock unit award recipients have the right to 
receive dividends, however, restricted stock units do not have any other rights of absolute ownership. 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 and restricted share units 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.

(1) Includes restricted stock units issued to employees in the PCLI acquisition.

In  connection  with  our  February  1,  2017  PCLI  acquisition,  we  issued  472,276  restricted  stock  units  to  PCLI  employees  as 
replacement units for unvested awards issued under the legacy PCLI plan. The fair value of these awards totaled $13.3 million
and is based on a February 1, 2017 grant date value of $28.12 per unit. Of this total, $6.6 million is recognized as an increase to 
our PCLI purchase price as it represents the value of the awards attributable to pre-acquisition services, and the remaining $6.7 
million is to be recognized as compensation expense over the two-year vesting period.

For the years ended December 31, 2017, 2016 and 2015, restricted stock and restricted stock units vested having a grant date fair 
value of $24.9 million, $18.4 million and $14.2 million, respectively. For the years ended December 31, 2016 and 2015, we granted 
restricted stock and restricted stock units having a weighted average grant date fair value of $21.66 and $49.92, respectively. As 
of December 31, 2017, there was $33.9 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% of target award 
amounts. As of December 31, 2017, estimated share payouts for outstanding non-vested performance share unit awards averaged 
approximately 110% of target amounts.

A summary of performance share unit activity and changes during the year ended December 31, 2017 is presented below:

NOTE 7:  Cash and Cash Equivalents and Investments in Marketable Securities

Our investment portfolio at December 31, 2017 consisted of cash and cash equivalents.

We periodically 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 and are reported at fair value. 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.

Inventories which are valued at the lower of LIFO cost or market reflect a valuation reserve of $223.8 million and $332.5 million
at December 31, 2017 and 2016, respectively. The December 31, 2016 market reserve of $332.5 million was reversed due to the 
sale of inventory quantities that gave rise to the 2016 reserve. A new market reserve of $223.8 million was established as of 
December 31, 2017 based on market conditions and prices at that time. The effect of the change in the lower of cost or market 
reserve was a decrease to cost of goods sold of $108.7 million and $291.9 million for the years ended December 31, 2017 and 
2016, respectively, and an increase of $227.0 million for the year ended December 31, 2015.

At December 31, 2017, 2016 and 2015, the LIFO value of inventory, net of the lower of cost or market reserve, was equal to current 
costs.

In May 2017, the EPA granted the Cheyenne Refinery a one-year small refinery exemption from the Renewable Fuel Standard 
(“RFS”) program requirements for the 2016 calendar year. As a result, the Cheyenne Refinery’s gasoline and diesel production 
are not subject to the percentage of production that must satisfy a Renewable Volume Obligation (“RVO”) for 2016. In September 
2017, the EPA reinstated the RINs previously submitted to meet our Cheyenne Refinery’s 2016 RVO. The cost of the RINs used 
earlier to satisfy the Cheyenne Refinery’s 2016 RVO of $30.5 million was charged to cost of products sold in 2016. In the second 
quarter of 2017, we increased our inventory of RINs and reduced our cost of products sold by this amount, representing the cost 
of the RINs that were reinstated as a result of the RFS exemption received by the Cheyenne Refinery. 

Additionally, in December 2017, the EPA granted the Woods Cross Refinery a one-year small refinery exemption from the RFS 
program requirements for the 2016 calendar year. In the fourth quarter of 2017, we increased our inventory of RINs and reduced 
our cost of products sold in the amount of $27.3 million, representing the cost of the RINs to be reinstated as a result of the RFS 
exemption received by the Woods Cross Refinery. These RINs were reinstated in January 2018.

NOTE 10:  Goodwill and Long-lived Asset Impairment

As of December 31, 2017, our goodwill balance was $2.2 billion. During 2017, we recognized $194.8 million in goodwill as a 
result of our PCLI acquisition. Also during 2017, HEP recognized $21.6 million in goodwill as a result of the acquisition of HEP's 
remaining interests in SLC Pipeline and Frontier Pipeline. See Note 20 for additional information on our segments. The carrying 
amount of our goodwill may fluctuate from period to period due to the effects of foreign currency translation adjustments on 
goodwill assigned to our Lubricants and Specialty Products segment.

We performed our annual goodwill impairment testing as of July 1, 2017 and determined the fair value of our El Dorado reporting 
unit exceeded its carrying value by approximately 10%. A reasonable expectation exists that future deterioration in gross margins 
could result in an impairment of goodwill and the long-lived assets of the El Dorado reporting unit as some point in the future and 
such impairment charges could be material. Additionally, qualitative testing indicated no impairment of goodwill attributable to 
our other reporting units.

During the second quarter of 2017, we incurred long-lived asset impairment charges totaling $23.2 million, including $19.2 million
of construction-in-progress consisting primarily of engineering work for a planned expansion of our Woods Cross refinery to add 
lubricants production capabilities. During the second quarter of 2017, we concluded to no longer pursue this expansion for various 
reasons including our recent acquisition of PCLI. The remaining $4.0 million in charges relate to property, plant and equipment 
that we expensed in the form of accelerated depreciation in the income statement. Additionally, as a result of our impairment 
testing in the second quarter of 2016, we determined that the carrying value of the long-lived assets of the Cheyenne Refinery had 
been impaired and recorded long-lived asset impairment charges of $344.8 million that principally related to properties, plant and 
equipment.

During the second quarter of 2016, we performed interim goodwill impairment and related long-lived asset impairment testing of 
our El Dorado and Cheyenne Refinery reporting units after identifying a combination of events and circumstances that are indicators 
of potential goodwill and long-lived asset impairment. The indicators included lower than typical gross margins during the summer 
driving season, a decrease in the gross margin outlook and decrease in our market capitalization due to a decline in our common 
share price. Our testing first assessed the carrying values of our refining long-lived asset groups for recoverability. This entailed 
a comparison of our reporting unit fair values relative to their respective carrying values. If carrying value exceeds fair value for 
a reporting unit, we measure goodwill impairment as the excess of the carrying amount of reporting unit goodwill over the implied 
fair value of that goodwill based on estimates of the fair value of all assets and liabilities in the reporting unit. The estimated fair 
values of our goodwill reporting units and long-lived asset groups were derived using a combination of both income and market 
approaches. The  income  approach  reflects  expected  future  cash  flows  based  on  estimates  of  future  crack  spreads,  forecasted 
production levels, operating costs and capital expenditures. Our market approaches include both the guideline public company 
and guideline transaction methods. Both methods utilize pricing multiples derived from historical market transactions of other 
like-kind  assets. These  fair  value  measurements  involve  significant  unobservable  inputs  (Level  3  inputs). As  a  result  of  our 
impairment testing during the second quarter of 2016, we determined that the carrying value of the Cheyenne Refinery’s goodwill 
was fully impaired and a goodwill impairment charge of $309.3 million was recorded, representing all of the goodwill allocated 
to our Cheyenne Refinery. Our interim testing in 2016 did not identify any impairment related to our El Dorado reporting unit.

There were no impairments of goodwill or long-lived assets during the year ended December 31, 2015.

NOTE 11:  Environmental

We expensed $13.1 million, $6.6 million and $14.7 million for the years ended December 31, 2017, 2016 and 2015, respectively, 
for environmental remediation obligations. The accrued environmental liability reflected in our consolidated balance sheets was 
$103.7  million  and  $96.4  million  at  December 31,  2017  and  2016,  respectively,  of  which  $89.6  million  and  $82.9  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). The amount of our accrued liability includes $2.9 
million of environmental obligations assumed in connection with our February 1, 2017 PCLI acquisition. Estimated liabilities 
could increase in the future when the results of ongoing investigations become known, are considered probable and can be reasonably 
estimated.

NOTE 12:  Debt

HollyFrontier Credit Agreement
We  have  a  $1.35  billion  senior  unsecured  revolving  credit  facility  maturing  in  February  2022  (the  “HollyFrontier  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. During the year ended December 31, 2017, we received advances totaling 
$26.0 million and repaid $26.0 million under the HollyFrontier Credit Agreement. At December 31, 2017, we were in compliance 
with all covenants, had no outstanding borrowings and had outstanding letters of credit totaling $2.8 million under the HollyFrontier 
Credit Agreement. 

Indebtedness under the HollyFrontier Credit Agreement bears interest, at our option at either a) an alternate base rate (as defined 
in the credit agreement) plus an applicable margin of (ranging from 0.125% - 1.000%), b) LIBOR plus an applicable margin 
(ranging from 1.125% to 2.000%), or c) Canadian Dealer Offered Rate plus an applicable margin (ranging from 1.125% to 2.000%) 
for Canadian dollar denominated borrowings.

HEP Credit Agreement
HEP has a $1.4 billion senior secured revolving credit facility maturing in July 2022  (the “HEP Credit Agreement”) and is available 
to fund capital expenditures, investments, acquisitions, distribution payments, working capital and for general partnership purposes. 
It is also available to fund letters of credit up to a $50 million sub-limit and has a $300 million accordion. During the year ended 
December 31, 2017, HEP received advances totaling $969.0 million and repaid $510.0 million under the HEP Credit Agreement. 
At December 31, 2017, HEP was in compliance with all of its covenants, had outstanding borrowings of $1,012.0 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 3.73%
and 2.98% at December 31, 2017 and 2016, respectively. 

HEP’s obligations under the HEP Credit Agreement are collateralized by substantially all of HEP’s assets and are guaranteed by 
HEP's material 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
In March 2016 and November 2016, we issued $250 million and $750 million, respectively, in aggregate principal amount of 
5.875% senior notes (the “HollyFrontier Senior Notes”) maturing April 2026. The HollyFrontier Senior Notes are unsecured and 
unsubordinated  obligations  of  ours  and  rank  equally  with  all  our  other  existing  and  future  unsecured  and  unsubordinated 
indebtedness.

In June 2015, we redeemed our $150.0 million aggregate principal amount of 6.875% senior notes maturing November 2018 at a 
redemption cost of $155.2 million at which time we recognized a $1.4 million early extinguishment loss consisting of a $5.2 million
debt redemption premium, net of an unamortized premium of $3.8 million.

HollyFrontier Financing Obligation
In March 2016, we extinguished a financing obligation at a cost of $39.5 million and recognized an $8.7 million loss on the early 
termination. The financing obligation related to a sale and lease-back of certain crude oil tankage that we sold to an affiliate of 
Plains in October 2009 for $40.0 million. 

HollyFrontier Term Loan
In April 2016, we entered into a $350 million senior unsecured term loan (the “HollyFrontier Term Loan”) maturing in April 2019. 
The HollyFrontier Term Loan was fully repaid with proceeds received upon the November 2016 issuance of the HollyFrontier 
Senior Notes.

HEP Senior Notes
In July 2016 and September 2017, HEP issued $400 million and $100 million, respectively, in aggregate principal amount of 6.0%
HEP senior notes in a private placement. HEP used the net proceeds to repay indebtedness under the HEP Credit Agreement.

HEP's 6.0% senior notes ($500 million aggregate principal amount maturing August 2024) (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 January 2017, HEP redeemed its $300 million aggregate principal amount of 6.5% senior notes maturing March 2020 at a 
redemption cost of $309.8 million, at which time HEP recognized a $12.2 million early extinguishment loss consisting of a $9.8 
million debt redemption premium and unamortized discount and financing costs of $2.4 million. HEP funded the redemption with 
borrowings under the HEP Credit Agreement.

Indebtedness under the HEP Senior Notes is guaranteed by HEP’s wholly-owned subsidiaries. HEP’s creditors have no recourse 
to our assets. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries.

NOTE 13:  Derivative Instruments and Hedging Activities

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, forward purchase and sales 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. We also periodically 
have forward sales contracts that lock in the prices of future sales of crude oil and refined product and swap contracts serving as 
cash flow hedges against price risk on forecasted purchases of 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.

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 and forward sales under hedge accounting:

At December 31, 2017, we had a pre-tax net unrealized loss of $1.3 million classified in accumulated other comprehensive income 
that relates to all accounting hedges having contractual maturities through 2021. Assuming commodity prices remain unchanged, 
an unrealized gain of $0.1 million will be effectively transferred from accumulated other comprehensive income into the statement 
of income as the hedging instruments contractually mature over the next twelve-month period.

NOTE 14:  Income Taxes 

The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. The Act reduces the U.S. federal corporate tax rate 
from  35%  to  21%,  requires  companies  to  pay  a  one-time  transition  tax  on  earnings  of  certain  foreign  subsidiaries  that  were 
previously deferred and creates new taxes on certain foreign sourced earnings. At December 31, 2017, we have not completed our 
accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, we have made a reasonable 
estimate of the effects on our existing deferred tax balances, the one-time transition tax and related matters. For the items for which 
a reasonable estimate has been made, we recognized a provisional tax benefit amount of $307.1 million, which is included as a 
component of the income tax provision in 2017.

Provisional Amounts

Deferred Tax Assets and Liabilities:  We remeasured certain deferred tax assets and liabilities based upon the rates at which they 
are expected to reverse in the future, which is generally 25%. However, we are still analyzing certain aspects of the Act and refining 
our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax 
amounts. The provisional amount recorded that related to remeasurement of our deferred tax balance was a tax benefit of $315.0 
million. Included within our net deferred liability are deferred state income tax balances, which are recorded net of federal tax 
expense. While many states have not publicly commented on the changes in the Act, we have estimated the value of our state 
deferred tax balances based upon existing law and related guidance.

HOLLYFRONTIER CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Foreign Tax Effects:  The one-time transition tax is based on our foreign subsidiaries’ earnings and profits (“E&P”) arising 
primarily from our acquisition of PCLI in 2017. This E&P was previously deferred from U.S. income taxes at 35% plus the effect 
of U.S. state income tax, or together generally 38%. We previously provided deferred U.S. taxes for the repatriation of these 
deferred amounts. At December 31, 2017, we recorded a provisional amount for our one-time transition tax liability of $6.5 million
for our foreign subsidiaries at 15.5% plus the effect of state income tax, or together generally 20%. We have not yet completed 
our calculation of the total foreign E&P for these foreign subsidiaries. This amount may change when we finalize the calculation 
of foreign E&P previously deferred from U.S. federal taxation. Additional income taxes have been provided for the remaining 
outside basis difference inherent in these entities at 21% plus the effect of U.S. state income tax, or together generally 25% as 
these amounts are not considered to be indefinitely reinvested in foreign operations for which we have provided deferred taxes of 
$1.4 million.

Our accounting for these provisional amounts related to foreign tax effects is incomplete pending the completion of our analysis 
of E&P, the related US foreign tax credits and outside basis differences.

The provision for income taxes is comprised of the following:

At December 31, 2017 and 2016, there were $53.8 million and $22.1 million, respectively, of unrecognized tax benefits that, if 
recognized, would affect our effective tax rate. We had no unrecognized benefits at December 31, 2015. Unrecognized tax benefits 
are adjusted in the period in which new information about a tax position becomes available or the final outcome differs from the 
amount recorded. 

The 2016 and 2017 additions to unrecognized tax benefits relates to claims filed with the IRS on the federal income tax treatment 
of  refundable  biodiesel/ethanol blending  tax  credits  for  certain prior  years. The  issues  related  to  the  claims  are  complex  and 
uncertain, and we cannot conclude that it is more likely than not that we will sustain the claims. Therefore, no tax benefit has been 
recognized  for  the  filed  claims. We  believe  it  is  reasonably  possible  that  the  total  amounts  of  unrecognized  tax  benefits  will 
significantly increase within 12 months of the reporting date based on additional filings.

We recognize interest and penalties relating to liabilities for unrecognized tax benefits as an element of tax expense. We have not 
recorded any penalties related to our uncertain tax positions as we believe that it is more likely than not that there will not be any 
assessment of penalties. 

We are subject to U.S. and Canadian federal income tax, Oklahoma, Kansas, New Mexico, Iowa, Arizona, Utah, Colorado and 
Nebraska income tax and to income tax of multiple other state jurisdictions. We have substantially concluded all state and local 
income tax matters for tax years through 2012. Other than the federal claim noted above, we have materially concluded all U.S. 
federal income tax matters for tax years through December 31, 2013.

provide funds for the payment of payroll and income taxes due at the vesting of share-based awards, as well as other stock repurchases 
under separate authority from our Board of Directors.

In May 2015, our Board of Directors approved a $1 billion share repurchase program, which replaced all existing share repurchase 
programs, authorizing us to repurchase common stock in the open market or through privately negotiated transactions. The timing 
and amount of stock repurchases will depend on market conditions and corporate, regulatory and other relevant considerations. 
This program may be discontinued at any time by the Board of Directors. As of December 31, 2017, we had remaining authorization 
to repurchase up to $178.8 million under this stock repurchase program. 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.

During the years ended December 31, 2017, 2016 and 2015, we withheld shares of our common stock from certain employees in 
the amounts of $15.9 million, $4.7 million and $6.2 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.

NOTE 17:  Post-retirement Plans

In connection with our PCLI acquisition, we agreed to establish employee benefit plans including union and non-union pension 
plans and a post-retirement healthcare plan for PCLI employees that were previously covered under legacy Suncor plans.

Continued

Our agreement with Suncor also provides that pension assets related to the union and non-union pension plans will be transferred 
from the Suncor plans to a pension trust established by us and will be computed in accordance with the share purchase agreement, 
subject to regulatory approval. Our purchase price allocation as of February 1, 2017 included estimates of the amount of pension 
benefit obligation and the pension assets to be transferred using actuarial estimates. The actual asset transfer to our PCLI pension 
plan trust will be a cash transfer that is expected to occur in 2018. As of December 31, 2017, the plan asset balance represents a 
receivable for the pending transfer from the Suncor plans.

ended December 31, 2017:

Post-retirement Healthcare Plans
We have a post-retirement healthcare and other benefits plan that is available to certain of our employees who satisfy certain age 
and service requirements. This plan is unfunded and provides differing levels of healthcare benefits dependent upon hire date and 
work location. Not all of our employees are covered by this plan at December 31, 2017. In addition, we established a post-retirement 
healthcare and other benefits plan for our PCLI employees.

The following table sets forth the changes in the benefit obligation and plan assets of our post-retirement healthcare plans for the 
years ended December 31, 2017 and 2016:

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 $0.1 million, $0.1 million and $0.1 million for the years ended December 31, 2017, 2016 and 2015, 
respectively, in connection with this plan. The accrued liability reflected in the consolidated balance sheets was $2.7 million and 
$2.7 million at December 31, 2017 and 2016, respectively. As of December 31, 2017, the projected benefit obligation under this 
plan was $2.7 million. Annual benefit payments of $0.2 million are expected to be paid through 2027, which reflect expected future 
service.

Defined Contribution Plan
We have a defined contribution “401(k)” plan that covers substantially all U.S. employees. Our contributions are based on an 
employee's eligible compensation and years of service. We also partially match our employees’ contributions. We expensed $17.6 
million, $17.5 million and $17.2 million for the years ended December 31, 2017, 2016 and 2015, respectively, in connection with 
this plan.

NOTE 18:  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, 2017, the minimum future rental commitments under operating leases having non-cancellable 
lease terms in excess of one year are as follows:

Rental expense charged to operations was $95.7 million, $93.2 million and $107.3 million for the years ended December 31, 2017, 
2016 and 2015, respectively.

NOTE 19:  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.

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 2019 through 2033.

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 2018 through 2033. At December 31, 2017, the minimum 
future transportation and storage fees under transportation agreements having terms in excess of one year are as follows:

Transportation and storage costs incurred under these agreements totaled $140.5 million, $135.1 million and $137.7 million for 
the years ended December 31, 2017, 2016 and 2015, 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.

We have a crude oil supply contract that requires the supplier to deliver a specified volume of crude oil or pay a shortfall fee for 
the difference in the actual barrels delivered to us less the specified barrels per the supply contract. For the contract year ended 
August 31, 2017, the actual number of barrels delivered to us was substantially less than the specified barrels, and we recorded a 
reduction to cost of goods sold and accumulated a shortfall fee receivable of $26.0 million during this period. In September 2017, 
the supplier notified us they are disputing the shortfall fee owed and in October 2017 notified us of their demand for arbitration. 
We offset the receivable with payments of invoices for deliveries of crude oil received subsequent to August 31, 2017, which is 
permitted under the supply contract. We believe the disputes and claims made by the supplier are without merit.

In March, 2006, a subsidiary of ours sold the assets of Montana Refining Company under an Asset Purchase Agreement (“APA”). 
Calumet Montana Refining LLC, the current owner of the assets, has submitted requests for reimbursement of approximately 
$20.0 million pursuant to contractual indemnity provisions under the APA for various costs incurred, as well as additional claims 
related to environmental matters. We have rejected most of the claims for payment, and this matter is scheduled for arbitration 
beginning in July 2018. We have accrued the costs we believe are owed pursuant to the APA, and we estimate that any reasonably 
possible losses beyond the amounts accrued are not material.

NOTE 20:  Segment Information

Effective fourth quarter of 2017, we revised our reportable segments to align with certain changes in how our chief operating 
decision maker manages and allocates resources to our business. Accordingly, our Tulsa Refineries’ lubricants operations, previously 
reported  in  the  Refining  segment,  are  now  combined  with  the  operations  of  our  Petro-Canada  Lubricants  business  (acquired 
February 1, 2017) and reported in the Lubricants and Specialty Products segment. Our prior period segment information has been 
retrospectively adjusted to reflect our current segment presentation.

Our operations are organized into three reportable segments, Refining, Lubricants and Specialty Products and HEP. Our operations 
that are not included in the Refining, Lubricants and Specialty Products and HEP segments are included in Corporate and Other. 
Intersegment transactions are eliminated in our consolidated financial statements and are included in Eliminations. Corporate and 
Other and Eliminations are aggregated and presented under Corporate, Other and Eliminations column.

The Refining segment represents the operations of the El Dorado, Tulsa, Navajo, Cheyenne and Woods Cross Refineries and HFC 
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. HFC Asphalt operates various asphalt terminals 
in Arizona, New Mexico and Oklahoma.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Continued

The Lubricants and Specialty Products segment involves PCLI’s production operations, located in Mississauga,  Ontario, that 
includes lubricant products such as base oils, white oils, specialty products and finished lubricants, and the operations of our Petro-
Canada Lubricants business that includes the marketing of products to both retail and wholesale outlets through a global sales 
network  with  locations  in  Canada,  the  United  States,  Europe  and  China. Additionally,  the  Lubricants  and  Specialty  Products 
segment includes specialty lubricant products produced at our Tulsa Refineries that are marketed throughout North America and 
are distributed in Central and South America. 

The HEP segment  includes all of the operations of  HEP, which owns  and operates logistics and refinery assets  consisting of 
petroleum product and crude oil pipelines, terminals, tankage, loading rack facilities and processing units in the Mid-Continent, 
Southwest and Rocky Mountain regions of the United States. The HEP segment also includes a 75% ownership interest in UNEV 
(a consolidated subsidiary of HEP) and 50% ownership interest in each of the Osage Pipeline and the Cheyenne 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).

NOTE 21:  Significant Customers

We have two significant customers (Shell Oil and Sinclair), each of which has historically accounted for  approximately 10% of 
our annual revenues. Shell Oil accounted for $1,317.9 million (9%), $1,048.2 million (10%) and $1,252.6 million (9%) for the 
years ended December 31, 2017, 2016 and 2015, respectively, and Sinclair accounted for $1,135.7 million (8%), $927.0 million
(9%) and $1,104.9 million (8%) of our revenues for the years ended December 31, 2017, 2016 and 2015, respectively.

Non-U.S. sales represented 7% of our revenues for the year ended December 31, 2017. The Canadian market represents our largest 
concentration of foreign sales and accounted for 4% of our revenues for the year ended December 31, 2017.
