DEAR FELLOW SHAREHOLDERS

HollyFrontier operates in a dynamic industry. 
Market fundamentals and participants are 
continuously changing and evolving. We remain 
focused on leveraging our assets and businesses 
to both capitalize on near-term opportunities 
and better position our company for the long-
term. As we reflect on a strong year, we were well 
prepared to benefit from continued growth in 
North American crude production and to capture 
strategic opportunities that bring synergies, 
new capabilities and a broader platform to 
HollyFrontier. 

In 2018, HollyFrontier delivered strong financial 
results and solid growth across our three business 
segments. We made significant progress by 
setting strategic initiatives into motion and 
executing them across our operations: 

Lubricants and Specialty Products:

Through the acquisition of Red Giant Oil and 
the announcement to acquire Sonneborn, we 
extended our presence in high-margin finished 
lubricants and specialty products markets. 

Refining and Marketing:

Our ability to capture favorable feedstock 
discounts in Canadian and Permian crudes 
resulted in strong financial results.

Midstream: 

Holly Energy Partner’s (HEP) strong and steady 
cash flow generation helped extend its track-
record of increasing its quarterly distribution 
every quarter since its IPO in 2004.

Returning capital to shareholders remains a 
top priority. To that end, in 2018, HollyFrontier 
returned more than $597 million to shareholders 
through regular quarterly distributions of $204 
million and share repurchases totaling $393 
million. Since the merger of Holly Corporation and 
Frontier Oil Corporation in 2011, we have returned 
more than $5 billion of capital to shareholders.

HOLLYFRONTIER CORPORATION  2018 ANNUAL REPORT

We maintained our investment grade rating from 
S&P, Moody’s, and Fitch, underpinned by the 
Company’s excellent liquidity position and strong 
balance sheet. We continue to be well positioned 
to capitalize on growth opportunities while 
investing in our businesses and returning capital 
to our shareholders. 

WELL POSITIONED FOR VALUE CREATION

We made important progress over the last year, 
capitalizing on opportunities in a favorable market 
environment and positioning our three business 
segments for continued value creation. Our core 
values of health & safety, corporate citizenship, 
environmental stewardship, honesty & respect and 
continuous improvement consistently guide us as 
we operate our facilities safely and reliably, build 
out our lubricants business and benefit from the 
expansion of our midstream segment. 

Our performance as a company extends beyond 
our financial results. We are committed to 
delivering sustainable economic, environmental 
and social benefits to our neighbors, employees 
and shareholders. We invite you to learn about our 
environmental, social and governance efforts in 
our annual Corporate Citizenship Report. 

As we move forward, our employees remain 
the driving force that enables us to achieve 
and surpass our goals. Thanks to their effort, 
teamwork, and dedication to working safely and 
reliably, we expect to continue operating reliably 
and delivering exceptional performance. We are 
grateful for everything they do for our company. 

We look forward to updating you throughout 
2019. On behalf of our Board of Directors and 
our employees, thank you for your investment in 
HollyFrontier.

Sincerely,

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.

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.

deasphalter, FCC, HF alkylation, catalytic reforming, hydrodesulfurization, isomerization, sulfur recovery and product blending 
units. The facility typically processes or blends an additional 2,000 BPSD of natural gasoline, butane and gas oil over its 45,000 
BPSD capacity. 

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. 

The Woods Cross Refinery's primary market is Utah, which is currently supplied by a number of local refiners and the Pioneer 
Pipeline. It also supplies 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 to numerous terminals, including HEP's terminal at Spokane, Washington and to third-party 
terminals at Pocatello and Boise, Idaho and Pasco, Washington as well as to Cedar City, Utah and Las Vegas, Nevada via the 
UNEV Pipeline.

HOLLY ENERGY PARTNERS, L.P. 

HEP is a Delaware limited partnership that trades on the New York Stock Exchange under the trading symbol “HEP.” HEP 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 a 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 Osage Pipe Line Company, LLC, the owner 
of a pipeline running from Cushing, Oklahoma to El Dorado, Kansas (the “Osage Pipeline”) and Cheyenne Pipeline, LLC, the 
owner of a pipeline running from Fort Laramie, Wyoming to Cheyenne, Wyoming (the “Cheyenne Pipeline”).

HEP generates revenues by charging tariffs for transporting petroleum products and crude oil through its pipelines, by leasing 
certain pipeline capacity to Delek, by charging fees for terminalling and storing refined products and other hydrocarbons and 
providing other services at its storage tanks, terminals and refinery processing units. HEP does not take ownership of products 
that it transports, terminals, stores or refines; therefore, it is not directly exposed to changes in commodity prices.

HEP's recent acquisitions (2016 through present) are summarized below:

SLC Pipeline and Frontier Aspen
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.

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.

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. 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.

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. 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. The Osage pipeline is the primary pipeline that supplies our El Dorado Refinery with crude oil. 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 operator of the Osage Pipeline.

Transportation Agreements

Agreements with HEP
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 (“PPI”) or Federal Energy Regulatory Commission index. As of December 31, 2018, 
these agreements result in minimum annualized payments to HEP of $314.2 million.

Table of Content

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

Agreement with Delek
HEP has a 15-year pipelines and terminals agreement with Delek expiring in 2020, under which Delek has agreed to transport on 
HEP's pipelines and throughput through its terminals, volumes of refined products that results in a minimum level of annual 
revenue. The agreed upon tariff rates are increased or decreased annually at a rate equal to the percentage change in PPI, but will 
not decrease below the initial tariff rate. Also, HEP has a capacity lease agreement with Delek under which Delek leases space on 
HEP's Orla to El Paso pipeline for the shipment of up to 15,000 barrels of refined product per day. The terms under this agreement 
expire in 2020 through 2022.

Employees and Labor Relations
As of December 31, 2018, we had 3,622 employees, of which 1,158 are currently covered by collective bargaining agreements 
having various expiration dates between 2019 and 2020. We consider our employee relations to be good.

Environmental Regulation
We are subject to numerous international, 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.

17

Table of Content

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 - We are subject to the EPA’s Control of Hazardous Air Pollutants from Mobile Sources (also known as 
the Mobile Source Air Toxics rule, or “MSAT2”) regulations that impose reductions in the benzene content of our produced 
gasoline. In addition to reducing benzene concentration in our gasoline, our refineries currently purchase benzene credits to meet 
these requirements. If economically justified or otherwise determined to be beneficial, we may implement additional benzene 
reduction projects to eliminate or reduce 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 2018, the EPA finalized 
the RFS targets for 2019, which maintained the volume required for conventional (i.e., corn ethanol) renewable fuel, increased 
the volume required for advanced biofuels, and increased the volume required for cellulosic biofuel compared to the 2018 RFS 
requirements. The EPA also increased the biomass-based diesel volume for 2020 compared to 2019. 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. Lawsuits have been filed by the renewable fuel industry challenging the EPA's grant of small refinery exemptions. 
Additionally, in November 2017, the EPA denied petitions requesting to change the point of obligation for compliance under the 
RFS program to the terminal rack. Legal challenges of the EPA's decision may be expected. 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 renewable fuel 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.

Table of Content

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 was challenged in various courts, and the U.S. Supreme Court has 
stayed implementation of the rule. The U.S. Court of Appeals for the District of Columbia has held the litigation in abeyance. In 
October 2017, the EPA proposed to repeal the Clean Power Plan, and on August 21, 2018, the EPA proposed a replacement rule 
titled the Affordable Clean Energy Rule. Neither the Clean Power Plan nor the Affordable Clean Energy Rule would directly affect 
our operations. To the extent the EPA fully implements a rule that imposes higher costs on electricity generating units it could 
result in increased power costs for our refineries in future years.

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 United States.” 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 United States,” 
which expanded the regulatory reach of the existing CWA regulations. The final rule is currently stayed in 28 states as a result of 
litigation, but remains in effect in the District of Columbia as well as in 22 states and the U.S. territories. On February 28, 2017, 
the President of the United States issued an Executive Order directing the EPA and the Corps to rescind or revise the rule. On 
December 11, 2018, the EPA and the Corps proposed a revised definition of “waters of the United States,” but has not finalized 
the rulemaking process. If the 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.  

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, 2018, we had an accrual of $110.2 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 laws and 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. Some of 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 of process hazard analyses and third party compliance audits. However, many of the revised 
requirements do not become effective until 2021, but the EPA is engaged in an active rulemaking to rescind or amend significant 
elements of the RMP amendments. 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. Since the EPA first began mandating biofuels in excess of the “blend 
wall” (the 10% ethanol limit prescribed by most automobile warranties), the price of RINs has been extremely volatile. 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 and finished lubricant 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  and  finished  lubricant  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 and finished lubricant products can also be reduced due to a local or national recession or other adverse economic condition, 
which results in lower spending by businesses and consumers on gasoline and diesel fuel, higher gasoline prices due to higher 
crude oil prices, a shift by consumers to more fuel-efficient vehicles or alternative fuel vehicles (such as ethanol or wider adoption 
of  gas/electric  hybrid  vehicles),  or  an  increase  in  vehicle  fuel  economy,  whether  as  a  result  of  technological  advances  by 
manufacturers, legislation mandating or encouraging higher fuel economy or the use of alternative fuel. 

We do not produce crude oil and must purchase all our crude oil, the price of which fluctuates based upon worldwide and local 
market conditions. Our profitability depends largely on the spread between market prices for refined petroleum products and crude 
oil prices. This margin is continually changing and may fluctuate significantly from time to time. Crude oil and refined products 
are commodities whose price levels are determined by market forces beyond our control. For example, the reversal of certain 
existing pipelines or the construction of certain new pipelines transporting additional crude oil or refined products to markets that 
serve competing refineries could affect the market dynamic that has allowed us to take advantage of favorable pricing. 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 increase to cost of products sold in the amount of $136.3 million and 
a decrease of $108.7 million for the years ended December 31, 2018 and 2017, respectively.

A material decrease in the supply of crude oil or other raw materials available to our refineries and other facilities 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 and other facilities, there are a limited number of suppliers and, in 
some cases, we source from a single supplier and/or suppliers in economies that have experienced instability or the supplies are 
specific to the particular geographic region in which a facility is located. Any significant disruption in supply could affect our 
ability to obtain raw materials, or increase the cost of such raw materials, which could significantly reduce our production levels 
or have a material adverse effect on our business, financial condition and results of operations. In addition, certain raw materials 
that we use are subject to various regulatory laws, and a change in the ability to legally use such raw materials may impact our 
liquidity, financial position and results of operations.

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 or inaccurate assumptions about future 
synergies or revenues;
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. 

Our ability to grow our Lubricants and Specialty Products segment depends, in part, on our ability to continuously develop, 
manufacture and introduce new products and product enhancements on a timely and cost-effective basis, in response to customers’ 
demands for higher performance process lubricants, coatings, greases and other product offerings. Our competitors may develop 
new products or enhancements to their products that offer performance, features and lower prices that may render our products 
less competitive or obsolete, and, as a consequence, we may lose business and/or significant market share. Our efforts to respond 
to changes in consumer demand in a timely and cost-efficient manner to drive growth could be adversely affected by unfavorable 
margins or difficulties or delays in product development and service innovation, including the inability to identify viable new 
products, successfully complete research and development, obtain regulatory approvals, obtain intellectual property protection or 
gain market acceptance of new products or service techniques. The development and commercialization of new products require 
significant expenditures over an extended period of time, and some products that we seek to develop may never become profitable, 
and we could be required to write-off our investments related to a new product that does not reach commercial viability.  

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. 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. 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.

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,  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 international, federal, state, provincial 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  recent  acquisitions,  we  have  manufacturing  and  distribution  operations  in  foreign  countries  that  are  subject  to 
environmental laws and regulations of such 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.” By final rulemakings published in June and July 2018, the EPA established 
ozone air quality designations for the areas not addressed in its November 2017 rulemaking. 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 final 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 for certain process units and 
equipment, as well as fence line monitoring requirements. In November 2018, the EPA published amendments to the new rules 
to clarify and correct certain requirements. 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, international 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. 

25

Table of Content

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 governments of other foreign 
countries in which we operate. 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. Similar regulations may exist or be enacted in other foreign countries in which we operate.

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 and other disruptive risks 
for which we may not be adequately insured. 

Our operations are subject to catastrophic losses, operational hazards, unforeseen interruptions and other disruptive risks 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. 

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. 

27

Table of Content

We are not engaged in petroleum exploration and production activities and do not produce any of the crude oil feedstocks used at 
our refineries. We do not have a retail business and therefore are dependent upon others for outlets for our refined products. Certain 
of  our  competitors,  however,  obtain  a  portion  of  their  feedstocks  from  company-owned  production  and  have  retail  outlets. 
Competitors that have their own production or extensive retail outlets, with brand-name recognition, are at times able to offset 
losses from refining operations with profits from producing or retailing operations, and may be better positioned to withstand 
periods of depressed refining margins or feedstock shortages. 

In recent years there have been several refining and marketing consolidations or acquisitions between entities competing in our 
geographic market. These transactions could increase the future competitive pressures on us. 

The markets in which we compete may be impacted by competitors' plans for expansion projects and refinery improvements that 
could increase the production of refined products in our areas of operation and significantly affect our profitability.

Also, the potential operation of new or expanded refined product transportation pipelines, or the conversion of existing pipelines 
into refined product transportation pipelines, could impact the supply of refined products to our existing markets and negatively 
affect our profitability.

In addition, we compete with other industries that provide alternative means to satisfy the energy and fuel requirements of our 
industrial, commercial and individual consumers. The more successful these alternatives become as a result of governmental 
regulations, technological advances, consumer demand, improved pricing or otherwise, the greater the impact on pricing and 
demand for our products and our profitability. There are presently significant governmental and consumer pressures to increase 
the use of alternative fuels in the United States.  

A disruption to or proration of the refined product distribution systems or manufacturing facilities 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 and Magellan, 
SFPP and Plains, Chevron and UNEV, 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 have manufacturing facilities in foreign countries that support the Lubricants and Specialty Products segment. If one of our 
facilities is damaged or disrupted, resulting in production being halted for an extended period, we may not be able to timely supply 
our customers. We take steps to mitigate this risk, including business continuity and contingency planning and procuring property 
and  casualty  insurance  (including  business  interruption  insurance).  Nevertheless,  the  loss  of  sales  in  any  one  region  over  an 
extended period of time could have a material adverse effect on our business, financial condition and results of operations.

We may be subject to information technology system failures, network disruptions and breaches in data security. In addition, 
our business is subject to increasingly stringent data protection requirements.

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 are subject to laws, directives, and regulations relating to the collection, use, retention, disclosure, security and transfer of 
personal  data  relating  to  our  customers  and  employees.  These  laws,  directives  and  regulations,  and  their  interpretation  and 
enforcement continue to evolve and may be inconsistent from jurisdiction to jurisdiction. For example, the General Data Protection 
Regulation, which went into effect in the European Union on May 25, 2018, applies to all of our activities conducted in the 
European  Union  and  may  also  apply  to  related  products  and  services  that  we  offer  to  customers  in  the  European  Union. 
Noncompliance with these legal obligations relating to privacy and data protection could result in penalties, legal proceedings by 
governmental entities or  others,  and  significant  legal and  financial exposure  and  could  affect  our  ability to  retain  and  attract 
customers. 

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, 2018, we owned a 57% 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 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, 2018.

We are exposed to the credit risks, and certain other risks, of our key customers and vendors. 

We are subject to risks of loss resulting from nonpayment or nonperformance by our customers. We derive a significant portion 
of our revenues from contracts with key customers.

If any of our key customers default on their obligations to us, our financial results could be adversely affected. Furthermore, some 
of our customers may be highly leveraged and subject to their own operating and regulatory risks. In addition, nonperformance 
by vendors who have committed to provide us with products or services could result in higher costs or interfere with our ability 
to successfully conduct our business.  

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. On August 2, 2018, the EPA and NHTSA proposed the Safer Affordable Fuel 
Economy Rule which amended the existing CAFE standards and proposed new standards covering model years through 2026. A 
final rule is expected in 2019. 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. 

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. 

Potential product, service or other related liability claims and litigation could adversely affect our business, reputation 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. The development, manufacture 
and sale of specialty lubricant products also involves an inherent risk of exposure to potential product liability claims. These types 
of incidents could result in product liability claims from our customers. Our Lubricants and Specialty Products segment could 
also be subject to false advertising claims, product recalls, workplace exposure, product seizures and related adverse publicity.

Any of these incidents 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, reputation or results 
of operations or our ability to maintain existing customers or retain new customers. Although we maintain product and other 
general liability insurance, there can be no assurance that the types or levels of coverage maintained are adequate to cover these 
potential risks, or that we will be able to continue to maintain existing insurance or obtain comparable insurance at a reasonable 
cost, if at all.

In addition, if any party with whom we have a sponsorship relationship were to generate adverse publicity, our company could be 
harmed. A negative public perception of our company, whether justified or not, could impair our reputation, expose us to litigation, 
damage our brand equity and have a material adverse effect on our business.

We may be unable to adequately protect our intellectual property, which may limit our ability to compete in our markets.

We have trademarks and patents issued, applied for, or acquired in the United States and in various foreign countries, some of 
which may prove to be material to our business. Despite our efforts to protect such intellectual property, it is possible that competitors 
or other unauthorized third parties may obtain, copy, use or disclose our technologies, products, and processes. In addition, the 
laws and/or judicial systems of foreign countries in which we design, manufacture, market and sell our products may afford little 
or no effective protection of our intellectual property. These potential risks to our intellectual property could subject us to increased 
competition and negatively impact our liquidity, financial position and results of operations.

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. 

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. 

32

Table of Content

As of December 31, 2018, approximately 32% 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 
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 Notices of Violations issued in late 2016 and 2018 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

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. HFEDR will continue to work with 
the EPA and DOJ to resolve these matters.

Tulsa
HollyFrontier Tulsa Refining LLC (“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 working with the ODEQ and the EPA to document a settlement agreement.

Other 

We are a party to various other litigation and proceedings that we believe, based on advice of counsel, will not either individually

During the quarter ended December 31, 2018, 102,360 shares were withheld from certain executives and employees under the 
terms of our share-based compensation agreements to provide funds for the payment of payroll and income taxes due at vesting 
of restricted stock awards.

As of February 13, 2019, we had approximately 97,419 stockholders, including beneficial owners holding shares in street name.

We intend to consider the declaration of a dividend on a quarterly basis, although there is no assurance as to future dividends since 
they are dependent upon future earnings, capital requirements, our financial condition and other factors.

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 an independent petroleum refiner and marketer that produces high-value light products such as gasoline, diesel fuel, jet 
fuel and other specialty products. We own and operate refineries located in Kansas, Oklahoma, New Mexico, Wyoming and Utah 
and market our refined products principally in the Southwest U.S., the Rocky Mountains extending into the Pacific Northwest 
and in other neighboring Plains states. In addition, we produce base oils and other specialized lubricants in the U.S., Canada and 
the Netherlands, and export products to more than 80 countries. We also own a 57% limited partner interest and a non-economic 
general  partner  interest  in  HEP,  a  master  limited  partnership  that  provides  petroleum  product  and  crude  oil  transportation, 
terminalling, storage and throughput services to the petroleum industry, including HollyFrontier Corporation subsidiaries.

On November 12, 2018, we entered into an equity purchase agreement to acquire 100% of the issued and outstanding capital stock 
of Sonneborn. The acquisition closed on February 1, 2019. Cash consideration paid was $660.0 million. Sonneborn is a producer 
of specialty hydrocarbon chemicals such as white oils, petrolatums and waxes with manufacturing facilities in the United States 
and Europe.

On July 10, 2018, we entered into a definitive agreement to acquire Red Giant Oil, a privately-owned lubricants company. The 
acquisition closed on August 1, 2018. Cash consideration paid was $54.2 million. Red Giant Oil is one of the largest suppliers of 
locomotive engine oil in North America and is headquartered in Council Bluffs, Iowa with storage and distribution facilities in 
Iowa, Kansas, Utah and Wyoming, along with a blending and packaging facility in Texas.

On October 29, 2016, we 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 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, 2018, net income attributable to HollyFrontier stockholders was $1,098.0 million compared to 
net income of $805.4 million and a net loss of $260.5 million for the years ended December 31, 2017, and 2016, respectively. 
Overall gross refining margins per produced barrel sold for 2018 increased 53% over the year ended December 31, 2017 due to 
higher crack spreads and crude oil basis differentials.

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 $184.0 
million for the year ended December 31, 2018, which is net of the $97.0 million cost reduction resulting from small refinery RINs 
waivers granted by the EPA in 2018 as described in Note 8 “Inventories” in the Notes to Consolidated Financial Statements.

OUTLOOK

Going into 2019, despite tightening crude differentials, we are optimistic that strength in the diesel markets will continue, and we 
expect to see a seasonal rebound in gasoline markets. For the first quarter 2019, we expect to run between 400,000 and 410,000 
barrels per day of crude oil, primarily driven by the scheduled turnaround in mid-February at our Tulsa refinery.

37

Table of Content

In  our  Lubricants  and  Specialty  Products  segment,  the  Rack  Forward  business  continues  to  perform  well  based  on  strong 
macroeconomic conditions that support healthy demand and pricing for finished products. We expect this to be offset somewhat 
by further cyclical weakness and oversupply in the base oil markets which will depress Rack Back earnings in 2019.

At HEP, we anticipate an annual distribution growth rate of 2% and coverage to average 1.0x for the full year of 2019 with higher 
coverage ratios expected in the second half of the year due to contractual tariff escalators.

A more detailed discussion of our financial and operating results for the years ended December 31, 2018, 2017 and 2016 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

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

Results of Operations – Year Ended December 31, 2018 Compared to Year Ended December 31, 2017 

Summary
Net income attributable to HollyFrontier stockholders for the year ended December 31, 2018 was $1,098.0 million ($6.25 per 
basic and $6.19 per diluted share), a $292.6 million increase compared to net income attributable to HollyFrontier stockholders 
of $805.4 million ($4.54 per basic and $4.52 per diluted share) for the year ended December 31, 2017. Net income increased due 
principally to an increase in gross refining margins. For the year ended December 31, 2018, lower of cost or market inventory 
reserve adjustments decreased pre-tax earnings by $136.3 million compared to an increase of $108.7 million for the year ended 
December 31, 2017. Refinery gross margins for the year ended December 31, 2018 increased to $17.71 per produced barrel from 
$11.56  for  the  year  ended  December 31,  2017.  During  2018,  our  Cheyenne  Refinery  was  granted  a  one-year  small  refinery 
exemption from the EPA for the 2015 and 2017 calendar years and our Woods Cross Refinery was granted a one-year small refinery 
exemption for 2017. As a result of these exemptions, we recorded reductions totaling $97.0 million to our cost of products sold. 
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 $57.8 million decrease to our cost of products sold, reflecting the reinstatement of RINs previously 
expensed in 2016. 

Sales and Other Revenues
Sales and other revenues increased 24% from $14,251.3 million for the year ended December 31, 2017 to $17,714.7 million for 
the year ended December 31, 2018 due to a year-over-year increase in sales prices. Sales and other revenues for the years ended 
December 31, 2018 and 2017 include $108.4 million and $77.2 million, respectively, in HEP revenues attributable to pipeline and 
transportation  services  provided  to  unaffiliated  parties. Additionally,  sales  and  other  revenues  included  $1,799.5  million  and 
$1,594.0 million in unaffiliated revenues related to our Lubricants and Specialty Products segment for the years ended December 31, 
2018 and 2017.

Cost of Products Sold
Total cost of products sold increased 24% from $11,359.2 million for the year ended December 31, 2017 to $14,077.1 million for 
the year ended December 31, 2018, due principally to higher crude oil costs. Additionally, for the year ended December 31, 2018, 
we recognized a $136.3 million lower of cost or market inventory valuation charge compared to a benefit of $108.7 million for 
the same period of 2017, resulting in a new $360.1 million inventory reserve at December 31, 2018. The reserve at December 31, 
2018 is based on market conditions and prices at that time. During the years ended December 31, 2018 and 2017, we recorded 
$97.0 million and $57.8 million, respectively, RINs cost reduction as a result of our Cheyenne Refinery and Woods Cross Refinery 
small refinery exemptions.

Gross Refinery Margins
Gross refinery margin per barrel sold increased 53% from $11.56 for the year ended December 31, 2017 to $17.71 for the year 
ended December 31, 2018. 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,  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,  decreased  1%  from  $1,296.7  million  for  the  year  ended 
December 31, 2017 to $1,285.8 million for the year ended December 31, 2018 due principally to lower purchased fuel costs, 
partially offset by higher repair and maintenance costs as a result of a fire and resulting damage at our Woods Cross Refinery in 
March 2018. 

Selling, General and Administrative Expenses
Selling, general and administrative expenses increased 9% from $265.7 million for the year ended December 31, 2017 to $290.4 
million for the year ended December 31, 2018, due principally to higher legal and professional fees, salary costs and enterprise 
system initiatives. Additionally, we incurred $3.6 million in integration costs of our Petro-Canada Lubricants business during the 
year ended December 31, 2018 compared to $27.9 million during the year ended December 31, 2017.

Depreciation and Amortization Expenses
Depreciation and amortization increased 7% from $409.9 million for the year ended December 31, 2017 to $437.3 million for the 
year ended December 31, 2018. This increase was due principally to depreciation and amortization attributable to capitalized 
improvement projects and capitalized refinery turnaround costs. 

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. See Note 10 “Goodwill, 
Long-lived Assets and Intangibles” in the Notes to Consolidated Financial Statements for additional information on this impairment.

Interest Income
Interest income for the year ended December 31, 2018 was $16.9 million compared to $3.7 million for the year ended December 31, 
2017. This increase was due to higher interest rates and higher cash balances during 2018.

Interest Expense
Interest  expense  was  $131.4  million  for  the  year  ended  December 31,  2018  compared  to  $117.6  million  for  the  year  ended 
December 31, 2017. This increase was due to interest attributable to higher debt levels and market interest rate increases during 
the current year relative to 2017. For the years ended December 31, 2018 and 2017, interest expense included $71.9 million and 
$58.4 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.

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 $6.2 million and $16.9 million gains for the years ended December 31, 2018 and 
2017, respectively. The $6.2 million gain for 2018 consists of a $41.8 million gain on foreign exchange forward contracts (utilized 
as an economic hedge), net of a $35.6 million remeasurement loss on our intercompany financing structure.

Gain on Foreign Currency Swap
During the year ended December 31, 2017, we recorded a $24.5 million gain 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.

Income Taxes
For the year ended December 31, 2018, we recorded an income tax expense of $347.2 million compared to an income tax benefit 
of $12.4 million for the year ended December 31, 2017. Our effective tax rates, before consideration of earnings attributable to 
the noncontrolling interest, were 22.8% and (1.4)% for the years ended December 31, 2018 and 2017, 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.

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 Petro-Canada Lubricants business acquired in 2017. 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 $8,474.1 million for the year ended December 31, 2016 to $11,359.2 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 in 2016. 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, respectively, small refinery exemptions.

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 2017. 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  $1,021.2  million  for  the  year  ended 
December 31, 2016 to $1,296.7 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.

Selling, General and Administrative Expenses
Selling, general and administrative expenses increased 111% from $125.9 million for the year ended December 31, 2016 to $265.7 
million for the year ended December 31, 2017, due principally to $128.3 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.

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.

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, Long-lived Assets and Intangibles” 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.

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 2017 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 arrangement, 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 arrangement.

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.

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.

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. 

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. At December 31, 2018, we were in compliance with all covenants, had no 
outstanding borrowings and had outstanding letters of credit totaling $2.2 million under the HollyFrontier Credit Agreement.

Table of Content

HollyFrontier Financing Arrangements
In December 2018, certain of our wholly-owned subsidiaries entered into financing arrangements whereby such subsidiaries sold 
a portion of their precious metals catalyst to a financial institution and then leased back the precious metals catalyst in exchange 
for total cash received of $32.5 million. The volume of the precious metals catalyst and the lease rate are fixed over the one-year 
term of each lease, and the lease payments are recorded as interest expense. At maturity, we must repurchase the precious metals 
catalyst at its then fair market value.

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, 2018, HEP received advances totaling $337.0 million and repaid $426.0 million under the HEP Credit Agreement. 
At December 31, 2018, HEP was in compliance with all of its covenants, had outstanding borrowings of $923.0 million and no 
outstanding letters of credit 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
In May 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, 2018, HEP issued 171,246 common units under this program, providing $5.2 million in gross proceeds. As of 
December 31, 2018, HEP has issued 2,413,153 common units under this program, providing $82.3 million in gross proceeds.

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.

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  the  expansion  of  existing  units  at  our  facilities  and  selective 
acquisition of complementary assets for our refining operations intended to increase earnings and cash flow.

As of December 31, 2018, our cash and cash equivalents totaled $1,154.8 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.

In September 2018, 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, 2018, we had 
remaining authorization to repurchase up to $787.6 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  increased  $524.0  million  for  the  year  ended  December 31,  2018.  Net  cash  provided  by  operating 
activities of $1,554.4 million exceeded net cash used by investing and financing activities of $360.5 million and $664.3 million, 
respectively.

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 2019, 
we expect to spend approximately $510.0 million to $560.0 million in cash for capital projects and refinery turnarounds appropriated 
in 2019 and prior years. Refinery turnaround spending is amortized over the useful life of the turnaround. Our expected capital 
and turnaround cash spending for 2019 is as follows:

Type:

Capital
Turnarounds
Total

Expected Cash Spending Range
(In millions)

$

$

275.0
235.0
510.0

$

$

300.0
260.0
560.0

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.

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 2019 HEP capital budget is comprised of 
$10.0 million for maintenance capital expenditures and $20.0 million to $25.0 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. In addition, HEP may spend funds periodically 
to perform capital upgrades or additions to its assets where a customer reimburses HEP for such costs. The upgrades or additions 
would generally benefit the customer over the remaining life of the related service agreements.

Cash Flows – Financing Activities

Year Ended December 31, 2018 Compared to Year Ended December 31, 2017 
Net cash flows used for financing activities were $664.3 million for the year ended December 31, 2018 compared to $72.6 million
for the year ended December 31, 2017, an increase of $591.7 million. During the year ended December 31, 2018, we received 
$32.5 million in proceeds from our financing arrangement related to precious metals, purchased $363.4 million of treasury stock 
and paid $233.5 million in dividends. Also during this period, HEP received $337.0 million and repaid $426.0 million under the 
HEP Credit Agreement, received $114.8 million in net proceeds from the issuance of its common units and paid distributions of 
$125.7 million to noncontrolling interests. During the year ended December 31, 2017, we received $26.0 million and repaid $26.0

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.

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, 2018 and 2017, market values had fallen below historical 
LIFO inventory costs and, as a result, we recorded lower of cost or market inventory valuation reserves of $360.1 million and 
$223.8 million, respectively.

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

At December 31, 2018, our lower of cost or market inventory valuation reserve was $360.1 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, 2018, 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 
units 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 as of July 1, 2018 and determined there was no impairment of goodwill 
attributable to our 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, forward purchase and sales and futures contracts to mitigate price exposure with 
respect to our inventory positions, natural gas purchases, sales prices of refined products and crude oil costs.

Foreign Currency Risk Management
We are exposed to market risk related to the volatility in foreign currency exchange rates. We periodically enter into derivative 
contracts in the form of foreign exchange forward and foreign exchange swap contracts to mitigate the exposure associated with 
fluctuations on intercompany notes with our foreign subsidiaries that are not denominated in the U.S. dollar.

As of December 31, 2018, we have the following notional contract volumes related to all outstanding derivative contracts used 
to mitigate commodity price and foreign currency 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.

Table of Content

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, 2018 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, 
2018, outstanding borrowings under the HEP Credit Agreement were $923.0 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 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.

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 produced 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.

Management assessed the Company's internal control over financial reporting as of December 31, 2018 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, 2018, 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, 2018. That report appears on page 55.

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, 2018, 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, 2018, based on the COSO criteria.

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, 2018 and 2017, the related consolidated statements 
of income, comprehensive income, cash flows, and equity for each of the three years in the period ended December 31, 2018, and 
the related notes of the Company and our report dated February 20, 2019 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. 

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, 
2018 and 2017, the related consolidated statements of income, comprehensive income, cash flows, and equity for each of the three 
years in the period ended December 31, 2018, 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, 
2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 
2018, 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, 2018, 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 20, 2019 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.

outstanding capital stock of PCLI. The acquisition closed on February 1, 2017.

See Note 2 for additional information on these acquisitions.

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

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 since it presents our accounts 
receivables and payables consistent with our contractual settlement provisions.

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  at  both 
December 31, 2018 and 2017.

Accounts receivable attributable to crude oil resales generally represent the sell of excess crude oil 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 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.

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 $28.7 million and $24.8 million at December 31, 2018 and 2017, respectively, which are 
included in “Other long-term liabilities” in our consolidated balance sheets. Accretion expense was insignificant for the years 
ended December 31, 2018, 2017 and 2016. 

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 that are not subject to amortization 
are tested for impairment 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. 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. The carrying amount of our intangible 
assets and goodwill may fluctuate from period to period due to the effects of foreign currency translation adjustments on goodwill 
and intangible assets assigned to our Lubricants and Specialty Products segment.

Our long-lived assets principally consist of our refining assets that are organized as refining asset groups and our lubricants and 
specialty products business. 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 additional information regarding our goodwill and long-lived assets including impairment charges recorded during 
the years ended December 31, 2017 and 2016. 

Investments in Joint Ventures:  We account for investments in which we have a noncontrolling interest, yet have significant 
influence over the entity, using the equity method of accounting, whereby 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, 2018, HEP's underlying 
equity and recorded investment balances in the joint ventures are $39.3 million and $83.8 million, respectively. The differences 
are being amortized as adjustments to HEP's pro-rata share of earnings in the joint ventures.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Revenue Recognition:  Revenue on refined product and excess crude oil sales are recognized when delivered (via pipeline, in-
tank or rack) and the customer obtains control of such inventory, which is typically when title passes and the customer is billed. 
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 as cost of products sold. Additionally, our lubricants and specialty products 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, revenues and cost of revenues are deferred until the products have been sold to 
end customers. HEP recognizes revenues as products are shipped through its pipelines and terminals and as other services are 
rendered. Additionally, HEP has certain throughput agreements that specify minimum volume requirements, whereby HEP bills 
a customer for a minimum level of shipments in the event a customer ships below their contractual requirements. If there are no 
future performance obligations, HEP recognizes these deficiency payments as revenue. In certain of these throughput agreements, 
a customer may later utilize such shortfall billings as credit towards future volume shipments in excess of its minimum levels 
within its respective contractual shortfall make-up period. Such amounts represent an obligation to perform future services, which 
may be initially deferred and later recognized as revenue based on estimated future shipping levels, including the likelihood of a 
customer’s ability to utilize such amounts prior to the end of the contractual shortfall make-up period. HEP recognizes the service 
portion  of  these  deficiency  payments  as  revenue  when  HEP  does  not  expect  it  will  be  required  to  satisfy  these  performance 
obligations in the future based on the pattern of rights exercised by the customer. Payment terms under our contracts with customers 
are consistent with industry norms and are typically payable within 30 days of the date of invoice.

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 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  $110.9  million,  $112.9  million  and  $110.6  million  for  the  years  ended 
December 31, 2018, 2017 and 2016, 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.

66

HOLLYFRONTIER CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Continued

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.

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, 2018, 2017 and 2016, we received proceeds of $51.2 million, $47.4 million and $57.0 million and subsequently repaid $52.5 
million, $49.8 million and $58.0 million, respectively, under these sell / buy transactions.

Accounting Pronouncements - Recently Adopted

Accumulated Other Comprehensive Income
In February 2018, Accounting Standard Update (“ASU”) 2018-02, “Reclassification of Certain Tax Effects from Accumulated 
Other Comprehensive Income (“AOCI”),” was issued permitting a reclassification of stranded tax effects caused by the Tax Cuts 
and Jobs Act enacted on December 22, 2017 between AOCI and retained earnings. We adopted this standard effective in the first 
quarter of 2018 and recorded a cumulative effect adjustment of $3.6 million as an increase to AOCI and a decrease to retained 
earnings. During the third quarter of 2018, we completed analysis of the accounting for the stranded tax effects on AOCI and 
recorded an additional $3.1 million as an increase to AOCI and a decrease to retained earnings.

Hedge Accounting
In August 2017, 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 eased certain documentation and assessment requirements. We adopted 
this standard effective January 1, 2018 and recorded a cumulative effect adjustment of $0.1 million as a decrease to AOCI and an 
increase to retained earnings to eliminate the separate measurement of hedge ineffectiveness existing at the date of adoption. Our 
amended presentation and disclosures have been applied prospectively in Note 13.

Stock Compensation
In May 2017, ASU 2017-09, “Stock Compensation: Scope of Modification Accounting,” was issued to provide clarity to accounting 
for share-based payment awards in the event of a modification in the terms or conditions. We adopted this standard effective 
January 1, 2018, which did not affect our financial position, 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 pension 
cost and net periodic post-retirement cost (credit). We adopted this standard effective January 1, 2018 on a retrospective basis with 
the presentation of service cost separate from the other components of net periodic costs. The interest cost, expected return on plan 
assets and amortization of prior service credit have been reclassified from cost of products sold, operating expenses and selling, 
general and administrative expenses to other, net. The adoption of this standard had no impact on our financial condition, results 
of operations or cash flows.

Business Combinations
In January 2017, ASU 2017-01, “Business Combinations: Clarifying the Definition of a Business,” was issued clarifying the 
definition of a business with the objective of providing guidance to assist entities with evaluating whether transactions should be 
accounted for as acquisitions (or disposals) of assets or businesses. We adopted this standard effective January 1, 2018, which did 
not affect our financial position, results of operations or cash flows.

Cash Flow Presentation
In August 2016, ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments,” was issued clarifying how entities 
should classify certain cash receipts and cash payments in the statements of cash flows and amends certain disclosure requirements. 
We adopted this standard effective January 1, 2018, which did not affect our financial position, 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. We adopted this standard effective January 1, 2018, which resulted in changes to our revenue recognition policies on 
certain customer contracts. We have lubricant product sales agreements with U.S. and European marketers and distributors that 
provide rights of return provisions under which we repurchase such products and sell directly to end customers. Prior to January 
1, 2018, we recognized revenues and costs, net of allowances for expected returns under such agreements when such products 
were shipped to U.S. and European distributors. Effective with the adoption of ASU 2014-09, revenues and related product costs 
are no longer recognized when products are shipped to distributors, but rather, revenues and costs are recognized in earnings only 
when such products are ultimately sold to end customers.

We adopted this standard using the modified retrospective method, whereby the cumulative effect of applying the new standard 
was recorded as an adjustment to the opening balance of retained earnings as well as the carrying amounts of assets and liabilities 
as of January 1, 2018, which had no impact on our cash flows. The following reflects the cumulative effect of adoption as of 
January 1, 2018.

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 have elected 
to adopt using the modified retrospective transition method, whereby comparative prior period financial information will not be 
restated and will continue to be reported under the lease accounting standard in effect during those periods. We have also elected 
practical expedients provided by the new standard, including the package of practical expedients and the short-term lease recognition 
practical expedient, which allows an entity to not recognize leases with a term of 12 months or less on the balance sheet.

NOTE 2:  Acquisitions

Sonneborn
On November 12, 2018, we entered into an equity purchase agreement to acquire 100% of the capital stock of Sonneborn. The 
acquisition  closed  on  February  1,  2019.  Cash  consideration  paid  was  $660.0  million.  Sonneborn  is  a  producer  of  specialty 
hydrocarbon chemicals such as white oils, petrolatums and waxes with manufacturing facilities in the United States and Europe.

This acquisition will be accounted for as a business combination, with the cash purchase price allocated to the acquisition date 
fair value of assets and liabilities acquired. Due to the short timeframe between the closing of this acquisition and filing of this 
Annual Report on Form 10-K, we have  not completed the detailed valuation studies necessary to arrive at the required fair value 
estimates of the acquired Sonneborn assets, liabilities assumed and related purchase price allocations.

Red Giant Oil
On July 10, 2018, we entered into a definitive agreement to acquire Red Giant Oil, a privately-owned lubricants company. The 
acquisition closed on August 1, 2018. Cash consideration paid was $54.2 million. Red Giant Oil is one of the largest suppliers of 
locomotive engine oil in North America and is headquartered in Council Bluffs, Iowa.

This transaction was accounted for as a business combination using the acquisition method of accounting, with the purchase price 
allocated to the fair value of the acquired Red Giant Oil assets and liabilities as of the August 1 acquisition date, with the excess 
purchase price recorded as goodwill assigned to our Lubricants and Specialty Products segment. This goodwill is deductible for 
income tax purposes. Fair values are as follows: current assets $14.4 million, properties and equipment $21.3 million, intangible 
assets $9.7 million, goodwill $10.8 million and current liabilities $2.0 million. 

Our consolidated financial and operating results reflect the operations of Red Giant Oil beginning August 1, 2018. Our results of 
operations for the year ended December 31, 2018 included revenues and income before income taxes of $26.9 million and $1.2 
million, respectively, related to these operations.

PCLI
On October 29, 2016, we 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 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 was 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. Fair values are as follows: cash and cash equivalents $21.6 million, current assets $333.4 million, properties, plants 
and equipment $438.0 million, goodwill $194.8 million, intangibles and other noncurrent assets $124.3 million, current liabilities 
$87.4 million and deferred income tax and other long-term liabilities $118.0 million.

We incurred $3.6 million and $27.9 million, for the years ended December 31, 2018 and 2017, respectively, 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 a 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 Osage Pipeline Company, LLC, the owner of a pipeline running from Cushing, Oklahoma to El Dorado, Kansas 
(the “Osage Pipeline”) and Cheyenne Pipeline, LLC, the owner of a pipeline running from Fort Laramie, Wyoming to Cheyenne, 
Wyoming (the “Cheyenne Pipeline”).

At December 31, 2018, we owned a 57% 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 79% of HEP’s total revenues for the year ended December 31, 2018. 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 LLC and Frontier Aspen LLC 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 in the fourth quarter of 2017. 
The fair value of HEP's preexisting equity method investments in SLC Pipeline LLC and Frontier Aspen LLC was estimated using 
Level 3 inputs under the income method for these entities, adjusted for lack of control and marketability.

The total consideration of $363.8 million, consisting of cash consideration of $250.0 million and the fair value of HEP's preexisting 
equity method investments in SLC Pipeline LLC and Frontier Aspen LLC of $112.0 million, and working capital adjustments of 
$1.8 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. Fair values were as follows: cash and cash equivalents $4.6 million, 
current assets $5.2 million, properties and equipment $275.0 million, intangible assets $70.2 million, goodwill $13.8 million and 
current liabilities $5.0 million.

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.

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.

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, 2018, these 
agreements result in minimum annualized payments to HEP of $314.2 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  $110.0 million, which were used to repay 
indebtedness under the HEP Credit Agreement. 

HEP Common Unit Continuous Offering Program
In May 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, 2018, HEP issued 171,246 common units under this program, providing $5.2 million in gross proceeds. As  of 
December 31, 2018, HEP has issued 2,413,153 common units under this program, providing $82.3 million in gross proceeds.

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:  Revenues

Substantially all revenue-generating activities relate to sales of refined product and excess crude oil inventories sold at market 
prices (variable consideration) under contracts with customers. Additionally, we have revenues attributable to HEP logistics services 
provided under petroleum product and crude oil pipeline transportation, processing, storage and terminalling agreements with third 
parties.

As of December 31, 2018, we have long-term contracts with customers that specify minimum volumes of gasoline, diesel, lubricants 
and specialty products to be sold ratably at market prices through 2021. Such volumes are typically nominated in the month 
preceding delivery and delivered ratably throughout the following month. Future prices are subject to market fluctuations and 
therefore, we have elected the exemption to exclude variable consideration under these contracts under Accounting Standards

NOTE 5: 

Fair Value Measurements

Our financial instruments measured at fair value on a recurring basis consist of 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.

(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.

Level 1 Financial Instruments
Our NYMEX futures contracts are exchange traded and are measured and recorded at fair value using quoted market prices, a 
Level 1 input. 

Level 2 Financial Instruments
Derivative instruments consisting of foreign currency forward contracts, commodity price swaps and forward sales and purchase 
contracts are measured and recorded at fair value using Level 2 inputs. The fair value of the commodity price swap contracts is 
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 input and quoted forward commodity prices with 
respect to our commodity price swaps. RINs credit obligations are valued based on current market RINs prices. The fair value of 
foreign currency forward contracts are based on values provided by a third party, which were derived using market quotes for 
similar type instruments, a Level 2 input.

NOTE 6:  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

Stock-Based Compensation

We have a principal share-based compensation plan (the “Long-Term Incentive Compensation Plan”). The compensation cost 
charged against income for the plan was $39.0 million, $39.8 million and $22.8 million for the years ended December 31, 2018, 
2017 and 2016, respectively. Our accounting policy for the recognition of compensation expense for awards with pro-rata vesting 
is to expense the costs ratably over the vesting periods.

Additionally, HEP maintains a share-based compensation plan for Holly Logistic Services, L.L.C.'s non-employee directors and 
certain executives and employees. Compensation cost attributable to HEP’s share-based compensation plan was $3.2 million, $2.5 
million and $2.7 million for the years ended December 31, 2018, 2017 and 2016, 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 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 stock and restricted stock units lapse at which 
time they convert to common shares or cash. 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. 
We account for forfeitures on an estimated basis.

restricted stock and restricted stock units having a weighted average grant date fair value of $35.02 and $21.66, respectively. As 
of December 31, 2018, there was $34.0 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 or cash 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 or cash paid under these awards can range from zero
to 200% of target award amounts.

common stock upon the vesting of the performance share units having a grant date fair value of $6.6 million and $7.4 million, 
respectively. As of December 31, 2018, there was $14.2 million of total unrecognized compensation cost related to non-vested 
performance share units having a grant date fair value of $38.00 per unit. That cost is expected to be recognized over a weighted-
average period of 1.6 years.

(4)  Includes RINs

Our inventories that are valued at the lower of LIFO cost or market reflect a valuation reserve of $360.1 million and $223.8 million
at December 31, 2018 and 2017, respectively. The December 31, 2017 market reserve of $223.8 million was reversed due to the 
sale of inventory quantities that gave rise to the 2017 reserve. A new market reserve of $360.1 million was established as of 
December 31, 2018 based on market conditions and prices at that time. The effect of the change in the lower of cost or market 
reserve was an increase to cost of products sold of $136.3 million for the year ended December 31, 2018 and a decrease of $108.7 
million and $291.9 million for the years ended December 31, 2017 and 2016, respectively.

At December 31, 2018, 2017 and 2016, the LIFO value of inventory, net of the lower of cost or market reserve, was equal to current 
costs. For the year ended December 31, 2018, we recognized a charge of $49.6 million to cost of products sold as we liquidated 
certain quantities of LIFO inventory that were carried at historical acquisition costs above market prices at the time of liquidation.

During the three months ended June 30, 2018, the EPA granted the Woods Cross Refinery a one-year small refinery exemption 
from the Renewable Fuel Standard (“RFS”) program requirements for the 2017 calendar year end. As a result, the Woods Cross 
Refinery’s gasoline and diesel production are not subject to the Renewable Volume Obligation (“RVO”) for 2017. In the second 
quarter of 2018, we increased our inventory of RINs and reduced our cost of products sold by $25.3 million, representing the net 
cost of the Woods Cross Refinery’s RINs charge to cost of products sold in 2017, less the loss incurred for selling 2017 vintage 
RINs in excess of those which we can use subject to the 20% carryover limit.

During the three months ended March 31, 2018, the EPA granted the Cheyenne Refinery a one-year small refinery exemption from 
the RFS program requirements for the 2015 and 2017 calendar years end. As a result, the Cheyenne Refinery’s gasoline and diesel 
production are not subject to the RVO for those years. At the date we received the 2017 Cheyenne Refinery exemption, we had 
not yet retired RINs to satisfy the 2017 RVO, which we intended to satisfy, in part, with 2016 vintage RINs subject to the 20% 
carryover limit. In the first quarter of 2018, we increased our inventory of RINs and reduced our cost of products sold by $37.9 
million, representing the net cost of the Cheyenne Refinery’s RINs charged to cost of products sold in 2017, less the loss incurred 
from selling 2016 vintage RINs prior to their expiration in 2018.

In the first quarter of 2018, the EPA provided us 2018 vintage RINs to replace the RINs previously retired to meet the Cheyenne 
Refinery’s 2015 RVO. In the first quarter of 2018, we increased our inventory of RINs and reduced our cost of products sold by 
$33.8 million representing the fair value of the 2018 replacement RINs obtained from the Cheyenne Refinery’s exemption of its 
2015 RVO.

In May 2017, the EPA granted the Cheyenne Refinery a one-year small refinery exemption from the RFS program requirements 
for the 2016 calendar year. As a result, the Cheyenne Refinery’s gasoline and diesel production are not subject to the RVO for 
2016. In September 2017, the EPA reinstated the RINs previously retired 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 reinstated as a result of the RFS exemption 
received by the Woods Cross Refinery.

During the second quarter of 2018, the Renewable Fuel Association and three other associations sought judicial review of three 
hardship waivers granted by the EPA under the RFS provisions of the Clean Air Act by filing a lawsuit in the United States Court 
of Appeals for the Tenth Circuit (“Tenth Circuit”) that alleges the EPA erred in granting the waivers. This challenge includes two 
hardship waivers granted to our subsidiaries for the 2016 compliance year. The Tenth Circuit granted our motion to intervene in 
the case, thereby making us a party to this case. It is too early to assess whether the case is expected to have any impact on us.

NOTE 10:  Goodwill, Long-lived Assets and Intangibles

Goodwill and long-lived assets
As of December 31, 2018, our goodwill balance was $2.2 billion. During 2018, we recognized $10.8 million in goodwill as a 
result of our Red Giant Oil acquisition. Also during 2018, HEP recognized $3.6 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. There was no impairment of goodwill during the years ended 
December 31, 2018 and 2017. See below for discussion of our goodwill impairment recognized during the year ended December 
31, 2016.

In  2017,  we  incurred  long-lived  asset  impairment  charges  totaling  $23.2  million,  including  $19.2  million  of  construction-in-
progress that primarily related to engineering work for a planned expansion to add lubricants production capabilities at our Woods 
Cross Refinery as we concluded to no longer pursue 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.

During the second quarter of 2016, we performed interim impairment testing of our El Dorado and Cheyenne Refinery asset groups 
(also  representing  distinct  reporting  units  for  goodwill  impairment  testing)  after  identifying  a  combination  of  events  and 
circumstances that are indicators of potential long-lived asset and goodwill impairment. The indicators included lower than typical 
gross margins, a decrease in the gross margin outlook and decrease in our market capitalization due to a decline in our common 
share price. As a result, we determined that the carrying value of the Cheyenne Refinery asset group had been impaired and recorded 
long-lived asset impairment charges of $344.8 million that principally related to properties, plant and equipment and a goodwill 
impairment charge of $309.3 million.

Testing initially entailed an assessment of the carrying values of our refining asset groups for recoverability through a comparison 
of our asset group carrying values relative to its estimated future undiscounted cash flows. This assessment indicated impairment 
of the Cheyenne Refinery asset group had occurred. The impairment loss was measured as the excess of the carrying amount of 
the asset group over its respective fair value, which was 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).Our long-lived asset impairment testing 
did not identify any impairment related to our El Dorado Refinery asset group.

There was no impairment of long-lived assets during the year ended December 31, 2018.

Amortization expense was $16.6 million, $9.1 million and $3.1 million for the years ended December 31, 2018, 2017 and 2016, 
respectively and expected to approximate $16.7 million for each of the next five years.

NOTE 11:  Environmental

We expensed $14.8 million, $13.1 million and $6.6 million for the years ended December 31, 2018, 2017 and 2016, respectively, 
for environmental remediation obligations. The accrued environmental liability reflected in our consolidated balance sheets was 
$110.2  million  and  $103.7  million  at  December 31,  2018  and  2017,  respectively,  of  which  $93.8  million  and  $89.6  million, 
respectively, were classified as other long-term liabilities. These accruals include remediation and monitoring costs expected to 
be incurred over an extended period of time (up to 30 years for certain projects). 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. At December 31, 2018, we were in compliance with all covenants, had no 
outstanding borrowings and had outstanding letters of credit totaling $2.2 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, 2018, HEP received advances totaling $337.0 million and repaid $426.0 million under the HEP Credit Agreement. 
At December 31, 2018, HEP was in compliance with all of its covenants, had outstanding borrowings of $923.0 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 4.24%
and 3.73% at December 31, 2018 and 2017, 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.

HollyFrontier Financing Arrangements
In December 2018, certain of our wholly-owned subsidiaries entered into financing arrangements whereby such subsidiaries sold 
a portion of their precious metals catalyst to a financial institution and then leased back the precious metals catalyst in exchange 
for total cash received of $32.5 million. The volume of the precious metals catalyst and the lease rate are fixed over the one-year 
term of each lease, and the lease payments are recorded as interest expense. At maturity, we must repurchase the precious metals 
catalyst at its then fair market value. These financing arrangements are recorded at a Level 2 fair value totaling $32.9 million at 
December 31, 2018 and included in “Accrued liabilities” in our consolidated balance sheets. See Note 5 for additional information 
on Level 2 inputs.

In March 2016, we extinguished a financing arrangement at a cost of $39.5 million and recognized an $8.7 million loss on the 
early termination. The financing arrangement 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, sales prices of refined products and crude oil costs.

83

 
 
HOLLYFRONTIER CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Foreign Currency Risk Management
We are exposed to market risk related to the volatility in foreign currency exchange rates. We periodically enter into derivative 
contracts in the form of foreign exchange forward and foreign exchange swap contracts to mitigate the exposure associated with 
fluctuations on intercompany notes with our foreign subsidiaries that are not denominated in the U.S. dollar.

Accounting Hedges
We have swap contracts serving as cash flow hedges against price risk on forecasted purchases of natural gas and to lock in basis 
spread differentials on forecasted purchases of crude oil. 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.

Economic Hedges
We have commodity contracts including forward purchase and sell contracts and NYMEX futures contracts to lock in prices on 
forecasted purchases and sales of inventory, as well as swap contracts to lock in the crack spread of WTI and sub-octane gasoline, 
that serve as economic hedges (derivatives used for risk management, but not designated as accounting hedges). We also have 
forward currency contracts to fix the rate of foreign currency. Additionally, our catalyst financing arrangements discussed in Note 
12 could require repayment under certain conditions based on the future pricing of precious metals, which is an embedded derivative. 
These contracts are measured at fair value with offsetting adjustments (gains/losses) recorded directly to income.

At December 31, 2018, we had a pre-tax net unrealized gain of $9.9 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 $8.5 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 reduced the U.S. federal corporate tax rate 
from  35%  to  21%,  required  companies  to  pay  a  one-time  transition  tax  on  earnings  of  certain  foreign  subsidiaries  that  were 
previously deferred and created new taxes on certain foreign sourced earnings. At December 31, 2017, we had not completed our 
accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, we 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 had been made, we recognized a provisional tax benefit amount of $307.1 million, which was included as a 
component of the income tax provision in 2017.

For the year ended December 31, 2018, we completed the analysis of the accounting for the tax effects for which provisional 
adjustments were made during the fourth quarter of 2017, resulting in our recording during 2018 of an additional tax benefit of 
$7.8 million. These adjustments to the previously recorded provisional amounts included the effects on existing deferred tax 
balances, the one-time transition tax and deferred U.S. taxes on foreign subsidiaries earnings and profits.

Deferred Tax Assets and Liabilities:  For the year ended December 31, 2017, 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%.

Foreign Tax Effects:  The one-time transition tax was 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%, as we had not yet completed 
our calculation of the total foreign E&P for these foreign subsidiaries. In the course of preparing our U.S. federal income tax return 
during 2018, this amount changed slightly upon finalizing the calculation of foreign E&P previously deferred from U.S. federal 
taxation. Additional income taxes were 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 were not considered to be indefinitely reinvested 
in foreign operations for which we provided deferred taxes of $1.4 million.

At December 31, 2018, our accounting for these provisional amounts related to foreign tax effects is complete. Our one-time 
transition tax calculation was finalized during 2018 and the resulting liability determined to be $6.6 million.

The provision for income taxes is comprised of the following:

At December 31, 2018, 2017 and 2016, there were $53.8 million, $53.8 million, and $22.1 million, respectively, of unrecognized 
tax benefits that, if recognized, would affect our effective tax rate. 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. During the next 12 months, it is reasonably possible that an ultimate resolution regarding these 
claims could reduce unrecognized tax benefits (due to a court ruling in favor of the IRS). We do not expect these reductions to 
have a significant impact on our financial statements because such reductions would not significantly affect our annual effective 
tax rate.

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 2013. 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.

In September 2018, 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, 2018, we had 
remaining authorization to repurchase up to $787.6 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, 2018, 2017 and 2016, we withheld shares of our common stock from certain employees in 
the amounts of $19.6 million, $15.9 million and $4.7 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.

We expect to contribute $3.3 million to the PCLI pensions plans in 2019. Benefit payments, which reflect expected future service, 
are expected to be paid as follows: $1.0 million in 2019, $1.3 million in 2020, $1.5 million in 2021, $1.8 million in 2022, $2.0

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, 2018. In addition, we established a post-retirement

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, 2018, 2017 and 2016, 
respectively, in connection with this plan. The accrued liability reflected in the consolidated balance sheets was $2.3 million and 
$2.7 million at December 31, 2018 and 2017, respectively. As of December 31, 2018, the projected benefit obligation under this 
plan was $2.3 million. Annual benefit payments of $0.2 million are expected to be paid through 2028, 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 $19.1 
million, $17.6 million and $17.5 million for the years ended December 31, 2018, 2017 and 2016, respectively, in connection with 
this plan.

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.

We have made claims with our insurance providers for a business interruption related to a fire at our Woods Cross Refinery that 
occurred during 2018. These claims are currently being evaluated by our insurance providers. We account for business interruption 
insurance  recoveries  as  a  gain  contingency  and  only  recognize  such  recoveries  upon  resolution  of  the  claims  with  insurance 
providers. No amounts have been recognized to date for these business interruption claims.

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 2025.

We also have long-term agreements with third parties for the transportation and storage of crude oil, natural gas and feedstocks 
to our refineries and for terminal and storage services that expire in 2019 through 2039. At December 31, 2018, the minimum 
future transportation and storage fees under transportation agreements having terms in excess of one year are as follows:

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 products 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. For the second contract year ended August 31, 2018, the actual number of barrels 
delivered to us was less than the specified barrels, and we recorded a reduction to cost of products sold and accumulated a shortfall 
fee receivable of $8.0 million during this period. We offset the receivable with payments of invoices for deliveries of crude oil 
received subsequent to August 31, 2018, which is permitted under the supply contract. The shortfall fees owed for the second 
contract year are now also part of the arbitration proceedings. 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. Calumet has also asserted 
claims related to environmental matters. We have rejected all of the currently pending claims for payment, and selected issues 
were arbitrated in July 2018. In September 2018, the arbitration panel ruled on the selected issues and held that the APA places a 
number of important limitations on claims advanced by Calumet. The remaining issues are set to be heard by the arbitration panel 
in April 2019. We have accrued appropriate costs for this matter, and we believe that any reasonably possible losses beyond the 
amounts accrued are not material. 

NOTE 20:  Segment Information

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.

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. Also, effective with our acquisition that closed August 1, 2018, the Lubricants and 
Specialty Products segment includes Red Giant Oil, one of the largest suppliers of locomotive engine oil in North 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).

Item 9.  Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

We have had no change in, or disagreement with, our independent registered public accountants on matters involving accounting 
and financial disclosure.

Item 9A.  Controls and Procedures

Evaluation of disclosure controls and procedures.  Our principal executive officer and principal financial officer have evaluated, 
as required by Rule 13a-15(b) under the Securities Exchange Act of 1934 (the “Exchange Act”), our disclosure controls and 
procedures (as defined in Rules 13a-15(e) and 15d-15(e)) under the Exchange Act as of the end of the period covered by this 
annual  report  on  Form  10-K.  Our  disclosure  controls  and  procedures  are  designed  to  provide  reasonable  assurance  that  the 
information  we  are  required  to  disclose  in  the  reports  that  we  file  or  submit  under  the  Exchange Act  is  accumulated  and 
communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to 
allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods 
specified in the Securities and Exchange Commission's rules and forms. Based upon the evaluation, our principal executive officer 
and principal financial officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance 
level as of December 31, 2018.

Changes in internal control over financial reporting.  There have been no changes in our internal control over financial reporting 
(as defined in Rule 13a-15(f) under the Exchange Act) that occurred during our last fiscal quarter that have materially affected or 
are reasonably likely to materially affect our internal control over financial reporting.

See Item 8 for “Management's Report on its Assessment of the Company's Internal Control Over Financial Reporting” and “Report 
of the Independent Registered Public Accounting Firm.” 

Item 9B.  Other Information

There have been no events that occurred in the fourth quarter of 2018 that would need to be reported on Form 8-K that have not 
previously been reported.

Item 10.  Directors, Executive Officers and Corporate Governance
