DEAR FELLOW SHAREHOLDERS

2020 was an 
unprecedented year 
for HollyFrontier. In the 
face of extraordinary 
challenges, even as the 
COVID-19 pandemic and 
reduced global economic 
activity affected our 
businesses and our 
daily lives, HollyFrontier 
persevered and took 
important steps to strengthen our 
business and extend our long record of 
value creation.

We controlled what we could, focusing 
on the fundamentals of our business, 
maintaining a disciplined approach to 
capital allocation and continuing our 
efforts to further enhance reliability, 
safety and efficiency. We made key 
investments in renewable initiatives 
that will enable HollyFrontier to 
capture new opportunities as our 
industry evolves. We ended the year 
with a strong balance sheet, healthy 
liquidity and high-quality assets 
that position us to capitalize on our 
competitive advantages. Looking 
ahead to 2021 and beyond, I believe 
that HollyFrontier is well-positioned 
for long-term success as our core 
businesses rebound and we continue 
our expansion into renewables.

MEETING THE 
CHALLENGES OF 2020

Beyond the progress we are making 
with our business, I’m incredibly 
proud of how our team met the key 
challenges that defined 2020. 

In response to the COVID-19 pandemic, 
we took a number of actions to protect 
the health and safety of our employees 
while continuing safe and responsible 
operations. In addition to operating 
our facilities safely throughout the 
year, members of the HollyFrontier 
team stepped up to support first 
responders and healthcare workers by 
producing and donating hand sanitizer 
and 3D face shields. HollyFrontier 
employees also contributed their time 
and donated to many organizations, 
helping our neighbors hit hardest by 

the pandemic. I could not be more 
proud of this team as we continue to 
support these efforts today.

The impact of the COVID-19 pandemic 
on the global macro economy created 
unprecedented demand destruction 
for many of the transportation fuels, 
lubricants and specialty products 
we provide, as well as the associated 
transportation and terminal services 
we offer. As a result, volumes and 
unit margins across our businesses 
declined in 2020, resulting in lower 
gross margins and earnings. We saw 
an improvement in demand for our 
essential products in the second half of 
2020 and believe demand will recover 
to normalized levels in 2021. 

With respect to the calls for social 
justice, like many companies, 
HollyFrontier recognized the need 
to look internally and assess whether 
we as a company are providing the 
leadership and real opportunities 
that are expected of a company like 
HollyFrontier. We have prioritized our 
diversity efforts in terms of recruiting 
and hiring, and have also recently 
added new diverse members to our 
Board of Directors. HollyFrontier is 
proud of its increased diversity, from 
our boardroom to the field, and we are 
dedicated to continuous improvement 
on this front.

OPERATIONS

Despite the market environment, we 
took concrete actions to reinforce 
HollyFrontier’s already strong 
foundation across our Refining, 
Midstream, and Lubricants and 
Specialty Products business segments. 
Some highlights include: 

Refining: This segment performed well 
in safety and successfully managed 
large swings in throughput as customer 
demand was affected by the COVID-19 
pandemic. 

Looking ahead, we are prepared to 
meet demand as it rebounds and 
recapture incremental increases in 
margins. To achieve this, we will rely 
on the hallmarks of this business: the 

proximity of our four refineries to 
crude oil production basins with 
inland coastal crude discounts and 
the ability to process various crudes 
and produce a high percentage of 
gasoline, diesel fuel and other high 
value refined products. 

Midstream: HollyFrontier continues 
to benefit from Holly Energy Partners, 
L.P.’s (HEP) strong and stable cash 
flow stream. HEP’s system of crude 
pipelines, storage tanks, distribution 
terminal and loading rack facilities 
are positioned near HollyFrontier’s 
refining assets in high growth 
markets. In 2020, HEP achieved 
strong volume performance, driven 
by its oil pipeline systems in Wyoming 
and Utah, as well as its UNEV product 
pipeline. Throughout the year, HEP 
provided stability through its steady 
financial contribution and made 
progress on the expansion of its 
Frontier/SLC crude system.

Additionally, 2020 saw the 
commencement of field construction 
on a new 160,000 barrel per day 
crude oil pipeline that will connect 
the Cushing, Oklahoma crude oil hub 
to HollyFrontier’s Tulsa refinery.  The 
pipeline is owned by a joint venture 
between HEP and Plains All American 
Pipeline LP. The joint venture also 
owns and operates 1.5 million barrels 
of crude oil storage in Cushing, 
supporting HollyFrontier’s Tulsa and 
El Dorado refineries.

During the year, HEP reset its 
distribution strategy focused on 
funding all capital expenditures and 
distributions within free cash flow 
and maintaining distributable cash 
flow coverage of 1.3x or greater while 
reducing leverage to 3.0-3.5x EBITDA.

HollyFrontier Lubricants and 
Specialty Products (HFLSP): This 
segment produces base oils and 
specialty lubricants under the Petro-
Canada Lubricants, Sonneborn, Red 
Giant Oil (RGO) and HollyFrontier 
brands. It consists of “Rack Back” 
operations that capture the value 
between feedstock cost and base oil 
market prices and “Rack Forward” 

2

HOLLYFRONTIER CORPORATION  2020 ANNUAL REPORT

operations that capture the value 
between the base oil market prices 
and product sale revenues from its 
well-recognized brands and finished 
lubricants.

At the onset of the pandemic, HFLSP 
throughput was nearly halved, but 
the business bounced back quickly 
to generate strong earnings in the 
second half of the year. The strong 
second half performance has us 
excited about the growth and value 
creation prospects of the HFLSP 
business moving forward. 

Across all of our operations, safety 
continued to be our top priority 
in 2020. Despite the COVID-19 
pandemic, we achieved strong 
safety performance in 2020, with 
a 41% reduction in employee injury 
rates and 25% reduction in API Tier 
1 process safety incidents. We are 
committed to maintaining a safe work 
environment enriched by diversity 
and characterized by championing a 
culture of teamwork and ownership. 

DELIVERING SOLID  
FINANCIAL RESULTS

Resilient financial performance 
in 2020 reflected an 
emphasis on fundamentals, a 
disciplined approach to capital 
allocation, sound operational 
execution and our sustained 
concentration on safety and 
efficiency

By thoughtfully managing our balance 
sheet and liquidity position through 
the pandemic, HollyFrontier returned 
approximately $230 million to 
shareholders in 2020 through regular 
quarterly dividends. 

FOCUSING ON THE FUTURE  
WITH RENEWABLES

In 2020, we continued to advance 
HollyFrontier’s renewables strategy 
to diversify our business, meet the 
growing demand for lower carbon 
fuels and position HollyFrontier 
for sustainable, long-term success. 
Our industry is evolving, and 
there is a significant opportunity 
to enhance both the profitability 
and the environmental footprint 
of HollyFrontier through these 
investments. 

We began converting our Cheyenne 
refinery from a traditional petroleum 
fuels refinery into a renewable 
diesel facility, made major strides on 
engineering and procurement for the 
renewable diesel unit at our Navajo 
refinery in Artesia, New Mexico, and 
announced a feedstock pre-treatment 
unit in Artesia, New Mexico. Our 
investment in pre-treatment will 
enable our facilities to process a 
wider variety of feedstocks, allowing 
us to minimize feedstock risk while 
maximizing low carbon fuel standard 
value. 

When completed, our renewable 
diesel units are expected to produce 
over 200 million gallons and generate 
an expected $165 million in annual 
free cash flow excluding the blender’s 
tax credit. We expect to begin 
renewable diesel production in the 
first quarter of 2022.

In September of 2020, we successfully 
raised $750 million in a public bond 
offering, which will help support 
these projects. Looking ahead, we’re 
excited about the opportunity to 
strengthen HollyFrontier by placing 
it at the forefront of the next frontier 
in energy and will continue seeking 
opportunities to grow this area of our 
business. 

LOOKING AHEAD:  
WELL POSITIONED TO 
CAPITALIZE ON THE UP-CYCLE

We ended 2020 with solid 
operational performance and 
a strong financial foundation. 
We strategically maintain a 
conservative balance sheet, 
positioning HollyFrontier to 
withstand cyclicality while 
maintaining our strategic 
priorities. In 2021, our focus 
remains on generating high 
returns while operating safely 
and efficiently, further improving 
refinery reliability, progressing 
our transition into renewables, 
enhancing our environmental 
and sustainability performance 
and reporting, and continuing 
to prudently deploy capital to 
advance shareholders’ best 
interests.

Our resilience in 2020 was 
reflective of our team’s collective 
perseverance. Due to their 
work ethic and our collective 
commitment to safe and 
responsible operations, we were 
able to create value for our 
stakeholders. 

Our company’s prospects in 2021 
are promising as we look forward 
to better market conditions that 
will facilitate HollyFrontier’s 
continued growth, evolution and 
success. We expect to continue 
operating reliably and deliver 
exceptional performance. On 
behalf of our Board of Directors 
and our employees, thank you 
for your trust and investment in 
HollyFrontier.

Sincerely,

Michael C. Jennings

Chief Executive Officer  
and President

COMPANY OVERVIEW

References  herein  to  HollyFrontier  Corporation  (“HollyFrontier”)  include  HollyFrontier  and  its  consolidated  subsidiaries.  In 
accordance with the Securities and Exchange Commission's (“SEC”) “Plain English” guidelines, this Annual Report on Form 
10-K has been written in the first person. In 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 Holly Energy Partners, L.P. (“HEP”) and its subsidiaries 
as consolidated subsidiaries of HollyFrontier, unless when used in disclosures of transactions or obligations between HEP and 
HollyFrontier or its other subsidiaries. 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.

We are principally an independent petroleum refiner that produces high-value light products such as gasoline, diesel fuel, jet 
fuel, specialty lubricant products, and specialty and modified asphalt. We were incorporated in Delaware in 1947 and maintain 
our  principal  corporate  offices  at  2828  N.  Harwood,  Suite  1300,  Dallas,  Texas  75201-1507.  Our  telephone  number  is 
214-871-3555, and our internet website address is www.hollyfrontier.com. The information contained on our website does not 
constitute part of this Annual Report on Form 10-K. A print copy of this Annual Report on Form 10-K will be provided without 
charge upon written request to the Vice President, Investor Relations at the above address. A direct link to our SEC filings is 
available  on  our  website  under  the  Investor  Relations  tab.  Also  available  on  our  website  are  copies  of  our  Corporate 
Governance  Guidelines,  Audit  Committee  Charter,  Compensation  Committee  Charter,  Nominating  /  Corporate  Governance 
Committee Charter, Environmental, Health, Safety, and Public Policy Committee Charter and Code of Business Conduct and 
Ethics, all of which will be provided without charge upon written request to the Vice President, Investor Relations at the above 
address.  Our  Code  of  Business  Conduct  and  Ethics  applies  to  all  of  our  officers,  employees  and  directors,  including  our 
principal executive officer, principal financial officer and principal accounting officer. Our common stock is traded on the New 
York Stock Exchange under the trading symbol “HFC.”

In November 2019, we announced our plans to construct a new renewable diesel unit (“RDU”) at our Artesia facility. The RDU 
will  have  a  production  capacity  of  approximately  120  million  gallons  a  year  and  allow  us  to  process  soybean  oil  and  other 
renewable feedstocks into renewable diesel. This investment will provide us the opportunity to meet the demand for low-carbon 
fuels while covering the cost of our annual RINs purchase obligation under current market conditions.

In the third quarter of 2020, we permanently ceased petroleum refining operations at our Cheyenne Refinery and subsequently 
began  converting  certain  assets  at  our  Cheyenne  Refinery  to  renewable  diesel  production.  The  Cheyenne  RDU  will  have  a 
production capacity of approximately 90 million gallons a year. This decision was primarily based on a positive outlook in the 
market  for  renewable  diesel  and  the  expectation  that  future  free  cash  flow  generation  at  our  Cheyenne  Refinery  would  be 
challenged due to lower gross margins resulting from the economic impact of the COVID-19 pandemic and compressed crude 
differentials due to dislocations in the crude oil market. Additional factors included uncompetitive operating and maintenance 
costs forecasted for our Cheyenne Refinery and the anticipated loss of the Environmental Protection Agency’s (“EPA”) small 
refinery exemption.

Additionally, we are constructing a pre-treatment unit (“PTU”) at our Artesia facility that will provide feedstock flexibility for 
both our Artesia and Cheyenne RDUs. The RDUs and PTU, along with corresponding rail infrastructure and storage tanks, are 
estimated  to  have  a  total  capital  cost  of  $650  million  to  $750  million.  The  RDUs  are  expected  to  be  completed  in  the  first 
quarter of 2022 and the PTU in the first half of 2022. 

On November 12, 2018, we entered into an equity purchase agreement to acquire 100% of the issued and outstanding capital 
stock  of  Sonneborn  US  Holdings  Inc.  and  100%  of  the  membership  rights  in  Sonneborn  Coöperatief  U.A.  (collectively, 
“Sonneborn”).  The  acquisition  closed  on  February  1,  2019.  Cash  consideration  paid  was  $662.7  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  Company  LLC  (“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.

On October 29, 2016, we entered into a share purchase agreement with Suncor Energy Inc. (“Suncor”) to acquire 100% of the 
outstanding  capital  stock  of  Petro-Canada  Lubricants  Inc.  (“PCLI”).  The  acquisition  closed  on  February  1,  2017.  Cash 
consideration paid was $862.1 million, or $1.125 billion Canadian dollars. PCLI, located in Mississauga, Ontario, is the largest 
producer  of  base  oils  in  Canada  with  a  plant  having  15,600  BPD  of  lubricant  production  capacity  and  is  one  of  the  largest 
manufacturers of high margin Group III base oils in North America.

The El Dorado Refinery is located on 1,100 acres south of El Dorado, Kansas and is a fully integrated refinery. The principal 
processing units at the El Dorado Refinery consist of crude and vacuum distillation; hydrodesulfurization of naphtha, kerosene, 
diesel,  and  gas  oil  streams;  isomerization;  catalytic  reforming;  aromatics  recovery;  catalytic  cracking;  alkylation;  delayed 
coking; hydrogen production; and sulfur recovery.

The  Tulsa  West  facility  is  located  on  a  750-acre  site  in  Tulsa,  Oklahoma  situated  along  the  Arkansas  River.  The  principal 
processing  units  at  the  Tulsa  West  facility  consist  of  crude  and  vacuum  distillation  (with  light  ends  recovery),  naphtha 
hydrodesulfurization, propane de-asphalting, lubes extraction, MEK dewaxing, delayed coker and butane splitter units.

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

Markets and Competition
The  primary  markets  for  the  El  Dorado  Refinery's  refined  products  are  Colorado  and  the  Plains  States,  which  include  the 
Kansas City metropolitan area. The gasoline, diesel and jet fuel produced by the El Dorado Refinery are primarily shipped via 
pipeline  to  terminals  for  distribution  by  truck  or  rail.  We  ship  product  via  the  NuStar  Pipeline  Operating  Partnership  L.P. 
Pipeline  to  the  northern  Plains  States,  via  the  Magellan  Pipeline  Company,  L.P.  (“Magellan”)  mountain  pipeline  to  Denver, 
Colorado,  and  on  the  Magellan  mid-continent  pipeline  to  the  Plains  States.  Additionally,  HEP's  on-site  truck  and  rail  racks 
facilitate access to local refined product markets.

The El Dorado Refinery faces competition from other Plains States and Mid-Continent refiners, but the principal competitors 
for the El Dorado Refinery are Gulf Coast refiners. Our Gulf Coast competitors typically have lower production costs due to 
greater  economies  of  scale;  however,  they  incur  higher  refined  product  transportation  costs,  which  allows  the  El  Dorado 
Refinery to compete effectively in the Plains States and Rocky Mountain region with Gulf Coast refineries.

The Tulsa Refineries serve the Mid-Continent geographic region of the United States. Distillates and gasolines are primarily 
delivered  from  the  Tulsa  Refineries  to  market  via  pipelines  owned  and  operated  by  Magellan.  These  pipelines  connect  the 
refinery to distribution channels throughout Colorado, Oklahoma, Kansas, Missouri, Illinois, Iowa, Minnesota, Nebraska and 
Arkansas. Additionally, HEP's on-site truck and rail racks facilitate access to local refined product markets. 

The  Tulsa  Refineries’  principal  customers  for  conventional  gasoline  include  other  refiners,  convenience  store  chains, 
independent  marketers  and  retailers.  Truck  stop  operators  and  railroads  are  the  primary  diesel  customers.  Jet  fuel  is  sold 
primarily  for  commercial  use.  The  refinery's  asphalt  and  roofing  flux  products  are  sold  via  truck  or  railcar  directly  from  the 
refineries or to customers throughout the Mid-Continent geographic region primarily to paving contractors and manufacturers 
of roofing products.

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

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

Crude Oil and Feedstock Supplies
The Navajo Refinery is situated near the Permian Basin, an area that has historically, and continues to have, abundant supplies 
of crude oil available both for regional users and for export to other areas. We purchase crude oil from independent producers in 
southeastern  New  Mexico  and  west  Texas  as  well  as  from  major  oil  companies.  The  crude  oil  is  gathered  through  HEP's 
pipelines and through third-party tank trucks and crude oil pipeline systems for delivery to the Navajo Refinery.

We also purchase volumes of isobutane, natural gasoline and other feedstocks to supply the Navajo Refinery from sources in 
Texas and the Mid-Continent area that are delivered to our region on a common carrier pipeline owned by Enterprise Products, 
L.P.  Ultimately  all  volumes  of  these  products  are  shipped  to  the  Artesia  refining  facilities  on  HEP's  intermediate  pipelines 
running from Lovington to Artesia. From time to time, we purchase gas oil, naphtha and light cycle oil from other refiners for 
use as feedstock.

The Woods Cross Refinery currently obtains crude oil from suppliers in Canada, Wyoming and Utah as delivered via common 
carrier pipelines, including the SLC Pipeline and Frontier Pipeline owned by HEP. Supplies of black wax crude oil are shipped 
via truck.

Investment in Joint Venture

Cushing Connect Joint Venture
In  October  2019,  HEP  Cushing  LLC,  a  wholly-owned  subsidiary  of  HEP,  and  Plains  Marketing,  L.P.,  a  wholly-owned 
subsidiary  of  Plains  All  American  Pipeline,  L.P.  (“Plains”),  formed  a  50/50  joint  venture,  Cushing  Connect,  for  (i)  the 
development, construction, ownership and operation of a new 160,000 barrel per day common carrier crude oil pipeline (the 
“Cushing  Connect  Pipeline”)  that  will  connect  the  Cushing,  Oklahoma  crude  oil  hub  to  our  Tulsa  Refineries  and  (ii)  the 
ownership and operation of 1.5 million barrels of crude oil storage in Cushing, Oklahoma (the “Cushing Connect Terminal”). 
The Cushing Connect Terminal was fully in service beginning in April 2020, and the Cushing Connect Pipeline is expected to 
be placed in service during the second quarter of 2021. Long-term commercial agreements have been entered into to support the 
Cushing Connect assets. 

Cushing  Connect  will  contract  with  an  affiliate  of  HEP  to  manage  the  construction  and  operation  of  the  Cushing  Connect 
Pipeline  and  with  an  affiliate  of  Plains  to  manage  the  operation  of  the  Cushing  Connect  Terminal.  The  total  investment  in 
Cushing  Connect  will  be  shared  proportionately  among  the  partners,  and  HEP  estimates  its  share  of  the  cost  of  the  Cushing 
Connect  Terminal  contributed  by  Plains  and  Cushing  Connect  Pipeline  construction  costs  are  approximately  $65.0  million. 
However, any Cushing Connect Pipeline construction costs exceeding 10% of the budget are borne solely by HEP.

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  2021  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 (“FERC”) index. As of 
December  31,  2020,  these  agreements  required  minimum  annualized  payments  to  HEP  of  $351.1  million.  However,  as 
previously disclosed, subsequent to year end these agreements were modified to account for the conversion of our Cheyenne 
Refinery to renewable diesel production, and as of January 1, 2021, require minimum annualized payments to HEP of $341.9 
million.

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. 

As of December 31, 2020, HEP's assets included:

ADDITIONAL OPERATIONS AND OTHER INFORMATION

Corporate Offices
Our principal corporate offices are leased and located in Dallas, Texas. Functions performed in our Dallas office include overall 
corporate  management,  refinery  and  HEP  management,  planning  and  strategy,  corporate  finance,  crude  acquisition,  logistics, 
contract administration, marketing, investor relations, governmental affairs, accounting, tax, treasury, information technology, 
legal and human resources support functions. 

Human Capital
Our People
Our people differentiate us from our peers. Our “One HFC Culture” focuses on four key values – safety, integrity, teamwork 
and  ownership.  These  values  influence  our  decisions,  shape  our  behaviors  and  provide  the  opportunity  for  our  employees  to 
thrive. Safety is our first priority. We care about our people and have implemented policies and procedures designed to help 
make  sure  they  return  home  safely  every  day.  We  focus  on  integrity  and  doing  the  right  thing.  We  champion  a  culture  of 
teamwork  and  ownership  by  supporting  each  other  and  empowering  employees  to  take  action  where  they  see  a  need  or 
opportunity.

As  of  December  31,  2020,  we  had  3,891  employees  located  in  the  following  geographies:    2,933  employees  in  the  United 
States,  711  employees  in  Canada  and  247  employees  in  Europe  and  Asia.  As  of  December  31,  2020,  1,306  employees  were 
covered  by  collective  bargaining  agreements  with  various  expiration  dates  ranging  between  2021  and  2024.  We  have 
experienced no material interruptions of operations due to disputes with our employees and management attempts to have and 
believes that we have positive working relationships with our local unions and their members.

Oversight
Our  Board  of  Directors  and  Board  committees  provide  oversight  on  our  strategies  and  policies  related  to  human  capital 
management.  Our  Compensation  Committee  is  responsible  for  periodically  reviewing  HollyFrontier’s  strategies  and  policies 
regarding  the  promotion  of  employee  diversity,  equity  and  inclusion,  talent  and  performance  management,  pay  equity  and 
employee engagement, as well as our executive succession planning. Our Nominating, Governance and Social Responsibility 
Committee  oversees  our  policies  and  practices  regarding  human  rights  in  our  operations  and  supply  chain.  This  high  level 
oversight  is  designed  to  ensure  that  our  actions  are  well  aligned  with  our  strategies  in  attracting,  retaining  and  developing  a 
workforce that aligns with our values and strategies.

Diversity & Inclusion
Our leadership is committed to attracting, retaining and developing a highly engaged, high-performing, diverse workforce and 
cultivating an inclusive workplace where all employees feel valued and have a sense of belonging. Increasing our diversity and 
inclusion efforts is an organizational priority and strategic oversight of our efforts is provided by our Compensation Committee. 
We  have  introduced  diversity  awareness  programs  focused  on  increasing  the  number  of  underrepresented  persons  in 
engineering  roles  in  our  refineries  and  corporate  office.  Our  university  recruiting  team  has  partnered  with  historically  Black 
colleges  and  universities  to  offer  full-time  and  summer  internship  opportunities  and  various  diversity  and  inclusion 
organizations at universities to sponsor and participate in events, such as the North Texas Women’s Energy Network and the 
National  Society  of  Black  Engineers  Convention.  In  addition,  to  help  foster  a  culture  of  inclusion,  we  have  two  employee 
resource groups focused on strengthening our support of women and veterans in the workplace.

Health & Safety
The  safety  of  our  employees,  contractors  and  communities  is  an  overarching  priority  and  fundamental  to  our  operational 
success. We are grounded by our “Goal Zero” vision, which reflects our belief that safe production can be achieved each and 
every day. Our commitment to safety is embedded throughout our organization, from frontline employees and contractors to 
our  executive  leadership  and  board  of  directors.  Our  Operational  Excellence  Management  System  provides  the  framework 
through  which  we  identify,  monitor  and  reduce  risks.  Our  Environment,  Health  and  Safety  (“EHS”)  Leadership  Council, 
comprised of company executives, including our CEO, business unit leaders and corporate safety specialists, sets EHS strategy 
and reviews performance. The Environmental, Health, Safety and Public Policy Committee of our Board of Directors provides 
board-level oversight of our strategies and performance in these areas.

To achieve Goal Zero, our employee and contractor safety education and training programs are conducted on an ongoing basis. 
We set specific goals for workplace safety and measure attainment of those goals. Over the past five years ended December 31, 
2020, our OSHA total recordable incident rate (“TRIR”) declined by 35 percent. In response to the coronavirus (“COVID-19”) 
pandemic,  and  with  the  health  and  safety  of  our  employees  as  a  top  priority,  we  have  temporarily  modified  our  business 
practices  by  limiting  employee  and  contractor  presence  at  our  facilities  to  essential  operating  personnel,  using  a  work  from 
home policy, restricting travel, and quarantining employees when necessary.

Total Rewards & Development
We  believe  that  the  health  of  our  company  is  linked  to  the  performance  and  health  of  our  people.  We  want  to  inspire  and 
empower  our  employees  to  feel  confident  in  their  long-term  well-being  and  are  committed  to  offering  a  comprehensive  and 
competitive  total  rewards  programs  for  our  employees,  as  benchmarked  against  our  peers.  While  our  benefit  offerings  vary 
depending  on  each  country’s  market  practices,  they  are  designed  to  support  employee  health,  financial  and  emotional  needs. 
Our  benefits  include  comprehensive  coverage  for  health  care,  a  competitive  retirement  savings  benefit,  vacation  and  holiday 
time  and  other  income  protection  and  work  life  benefits.  We  also  provide  tools  to  help  recognize  and  reward  employee 
performance consistent with our One HFC Culture. 

Consistent with our culture of ownership and growth, we offer training, development and engagement programs across every 
level  of  our  organization  to  provide  employees  the  opportunity  to  develop  their  career  by  enhancing  skills  and  capabilities 
consistent with the needs of the business. In 2019, we launched HFC LEAD. “LEAD” stands for Leadership, Excellence and 
Development and is comprised of a number of programs focused on developing current and future leaders, including the Future 
HFC Leader Development, Front Line Leader, and Leading the HFC Way programs. We invested $6.0 million in our employee 
training and development programs in fiscal 2020.

Governmental Regulation
We are subject to numerous international, federal, state, provincial and local laws and regulations 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  and  regulations  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; the issuance of injunctive relief 
limiting or prohibiting certain operations; and reputational harm. In addition, many environmental laws provide a mechanism 
for  citizens  to  file  suit  against  regulated  facilities  for  alleged  environmental  violations.  Compliance  with  applicable 
environmental  laws,  regulations  and  permits  or  other  authorizations  will  continue  to  have  an  impact  on  our  operations,  the 
results of our operations and our capital expenditures.

Rate Regulation - Some of HEP’s existing pipelines are considered interstate common carrier pipelines subject to regulation by 
the Federal Energy Regulatory Commission (“FERC”) under the Interstate Commerce Act (the “ICA”). The ICA requires that 
tariff rates for oil pipelines, a category that includes crude oil and petroleum product pipelines, be just and reasonable and not 
unduly discriminatory. The ICA permits interested persons to challenge newly proposed or changed rates and authorizes FERC 
to suspend the effectiveness of such rates for a period of up to seven months and to investigate such rates. If, upon completion 
of an investigation, FERC finds that the new or changed rate is unlawful, it is authorized to require the carrier to refund the 
revenues  in  excess  of  the  prior  tariff  collected  during  the  pendency  of  the  investigation.  FERC  also  may  investigate,  upon 
complaint or on its own motion, rates that are already in effect and may order a carrier to change its rates prospectively. Upon 
an appropriate showing, a shipper may obtain reparations for damages sustained during the two years prior to the filing of a 
complaint.

The Energy Policy Act of 1992 deemed petroleum products pipeline tariff rates that were (i) in effect for the 365-day period 
ending on the date of enactment or (ii) in effect on the 365th day preceding enactment and had not been subject to complaint, 
protest or investigation during the 365-day period, in each case, to be just and reasonable or “grandfathered” under the ICA. 
The Energy Policy Act also limited the circumstances under which a complaint can be made against such grandfathered rates. 
Petroleum products pipelines may change their rates within prescribed ceiling levels that are tied to an inflation index. Shippers 
may  protest  rate  increases  made  within  the  ceiling  levels,  but  such  protests  must  show  that  the  portion  of  the  rate  increase 
resulting from application of the index is substantially in excess of the pipeline’s increase in costs from the previous year. A 
pipeline must, as a general rule, utilize the indexing methodology to change its rates. Cost-of-service ratemaking, market-based 
rates  and  settlement  rates  are  alternatives  to  the  indexing  approach  and  may  be  used  in  certain  specified  circumstances  to 
change rates.

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 facilities 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,  the  EPA  has  reduced  several  National  Ambient  Air  Quality  Standards  (“NAAQS”),  and  implementation  of  such 
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. The EPA 
has  not  yet  finalized  the  2021  RFS  requirements  for  any  fuel  other  than  biodiesel,  creating  some  uncertainty  regarding  our 
compliance  obligations  for  2021.    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. 
For  additional  information  regarding  risks  relating  to  our  small  refinery  exemptions,  see  Item  1A,  “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.”  Legal  challenges  of  the  EPA's  decision  are  ongoing.  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 incur 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  requirements,  other  CAA  requirements,  and  other 
presently  existing  or  future  environmental  regulations  may  cause  us  to  make  substantial  capital  expenditures  and  purchase 
sulfur credits at significant cost to enable our refineries to produce products that meet applicable requirements.

Climate Change - In recent years, various legislative and regulatory measures to address climate change and greenhouse gas 
(“GHG”) emissions (including carbon dioxide, methane and nitrous oxides) have been discussed or implemented. They include 
proposed and enacted federal regulation and state actions to develop statewide, regional or nationwide programs designed to 
control and reduce GHG emissions from fixed sources, such as our refineries, as well as power plants, mobile transportation 
sources  and  fuels.  Measures  to  date  have  included  but  are  not  limited  to  cap  and  trade  programs,  carbon  taxes,  vehicle 
efficiency standards, electric vehicle mandates, combustion engine phaseouts 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, in July 2019, the EPA issued a replacement rule titled the Affordable Clean Energy (“ACE”) Rule, which replaced 
the Clean Power Plan and is focused solely on electric generating units. However, in January 2021, the D.C. Circuit vacated the 
ACE  rule,  and  the  Biden  Administration  may  consider  reimplementing  the  Clean  Power  Plan  or  a  similar  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. There is also a risk that financial institutions will be required to adopt policies that 
have the effect of reducing the funding provided to the fossil fuel sector. Recently, the Federal Reserve announced that it has 
joined  the  Network  for  Greening  the  Financial  System,  a  consortium  of  financial  regulators  focused  on  addressing  climate-
related  risks  in  the  financial  sector.  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. 
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.

The incoming administration is proposing an “all of government” approach to climate change in which the federal government 
would use not only its regulatory and enforcement authority but also its policy and purchasing power to encourage investment 
and use of renewable energy sources and to otherwise impede and reduce fossil fuel use.  This approach may include elements 
that  could  directly  or  indirectly  result  in  decreased  demand  for  transportation  fuel  and  could  have  an  adverse  impact  on  our 
operations. For example, on January 27, 2021, President Biden issued an executive order that commits to substantial action on 
climate  change,  calling  for,  among  other  things,  the  increased  use  of  zero-emissions  vehicles  by  the  federal  government,  the 
elimination  of  subsidies  provided  to  the  fossil  fuel  industry,  and  increased  emphasis  on  climate-related  risks  across 
governmental agencies and economic sectors.

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.

20

Table of Content

The CWA also regulates filling or discharges to wetlands and other “waters of the United States.” On January 23, 2020, 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 narrowed the regulatory reach of the CWA regulations relative to a prior 2015 rulemaking. 
The final rule became effective June 22, 2020. Because the rule does not expand the scope of the CWA’s jurisdiction, it will not 
likely adversely impact our operations; however, the final rule is subject to litigation, and multiple challenges to the EPA's prior 
rulemakings  remains  pending,  both  of  which  create  uncertainty.  Additionally,  the  new  administration  may  seek  to  revise  or 
withdraw the final rule, creating further uncertainty. 

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.

Other  Environmental  Regulations  -  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, the Fisheries Act, the Greenhouse Gas Pollution Pricing Act and their 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. 
Regulatory  trends  towards  more  stringent  emission  requirements  and  operating  controls  are  expected  to  continue  at  federal, 
provincial and local levels.

Additionally, our assets and operations in the Netherlands are required to comply with Dutch regulations that are similar to, and 
in some cases more stringent than, those described above for our U.S. operations. The statutes to which our Dutch assets and 
operations are subject include the Environmental Protection Act, the Activities Decree, the Environmental Licensing (General 
Provisions) Act, the Water Act, the Soil Protection Act, the Major Accidents (Risks) Decree, the European Birds and Habitats 
Directive,  the  Economic  Offences  Act  and  other  subordinate  decrees  and  regulations  relative  to  environmental  control, 
permitting and enforcement. However, a large legislative operation is being developed that should lead to the integration of all 
environmental  laws  in  one,  being  the  Environment  and  Planning  Act,  which  is  expected  to  enter  into  force  in  January  2022. 
Generally, these regulations create a system of environmental permits covering the most significant emissions to water, air and 
soil,  as  well  as  other  environmental  impacts.  The  Netherlands  also  participates  in  certain  broader  European  legal  initiatives, 
including GHG cap and trade programs. Additionally, in December 2019, the High Council of the Netherlands upheld a court 
order for the government of the Netherlands to reduce the country's GHG emissions by 25% (compared to 1990) by 2020, and 
in January 2020,the Climate Act came into force, with the goal of significantly reducing GHG emissions by 49% (compared to 
1990)  by  2030  and  by  at  least  95%  (compared  to  1990)  by  2050.  Furthermore,  the  target  is  that  100%  of  the  electricity 
production will be CO2 neutral in 2050. The Climate Act also establishes that the government must prepare a Climate Plan. The 
first  Climate  Plan  covers  the  period  between  2021  and  2030  and  includes  measures  in  view  of  a  reduction  of  49%  of  GHG 
emissions in 2030. It is unclear what further measures the Dutch government will take to reduce GHG emissions pursuant to 
this law.

Enforcement  and  Litigation  Proceedings  -  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, 2020, we had an accrual of $115.0 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. 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”),  comparable  state  statutes,  Canadian  regulations 
applicable to our operations in Canada and Dutch regulations, including the Health and Safety Act, applicable to our operations 
in  the  Netherlands.  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 chemical accidents and 
any  resulting  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. Many of the revised requirements do not become effective until 2021, and 
the  EPA  issued  a  final  rule  in  December  2019  that  rescinded  several  of  the  requirements  of  the  2017  rule.    The  new 
administration  may  consider  reissuing  some  of  the  rescinded  requirements  or  making  other  changes.    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

Risk Factor Summary

Investing  in  us  involves  a  degree  of  risk.  You  should  carefully  consider  all  information  in  this  Form  10-K,  including  the 
Management’s Discussion & Analysis section and the financial statements and related notes, prior to investing in our common 
stock. These risks and uncertainties include, but are not limited to, the following:

Risks Related to our Business:

•

•

•

•

•

•

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.
To successfully operate our facilities, we are required to expend significant amounts for capital outlays and operating 
expenditures.  If  we  are  unable  to  complete  capital  projects  at  their  expected  costs  or  in  a  timely  manner,  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.
The COVID-19 pandemic or any other widespread outbreak of an illness or pandemic or other public health crisis, and 
actions taken in response thereto, as well as certain developments in the global oil markets, have had and may continue 
to  have  a  material  adverse  effect  on  our  operations,  business,  financial  condition  and  results  of  operations  and  cash 
flows.
Competition  in  the  refining  and  marketing  industry  and  in  our  lubricants  and  specialty  products  segment  is  highly 
competitive, an increase in competition could adversely affect our earnings and profitability.
A  disruption  to  or  proration  of  the  refined  product  distribution  systems  or  manufacturing  facilities  we  utilize  could 
negatively impact our profitability.  
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.

• 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.
Our acquisition strategy involves numerous risks, any of which could adversely affect us.
An  impairment  of  our  long-lived  assets  or  goodwill  could  reduce  our  earnings  or  negatively  impact  our  financial 
condition and results of operations.
Potential product, service or other related liability claims and litigation could adversely affect our business, reputation 
and results of operations.

• We sell many of our lubricants and specialty products through distributors, which presents risks that could adversely 

affect our operating results.
Our hedging transactions may limit our gains and expose us to other risks.

•

Risks Related to Government Regulation

•

•

There are various risks associated with greenhouse gases and climate change, including increased regulation of CO2 
emissions, that could result in increased operating costs and litigation and reduced demand for the refined products we 
produce and investment in our industry.
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.  

• We  are  subject  to  significant  regulation  and  oversight  by  governmental  agencies.  We  incur  significant  costs,  and 
expect to incur additional costs in the future, to comply with existing, new and changing environmental, energy, health 
and safety laws and regulations, and face potential exposure for environmental matters.

•

Our  business  is  subject  to  complex  and  evolving  global  laws,  regulations  and  security  standards  regarding  privacy, 
cybersecurity  and  data  protection,  which  could  result  in  claims,  increased  cost  of  operations,  or  otherwise  harm  our 
business.  

General Risk Factors

•

•

Cyberattacks, data security breaches, information technology system failures, network disruptions, terrorist attacks or 
domestic vandalism, continued global hostilities or other sustained military campaigns could have a material 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.

• 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..  Our credit facility contains certain covenants and restrictions that may constrain our business and 
financing activities.
Our business is subject to the risks of international operations, including currency fluctuations.

•
• We are exposed to the credit risks, and certain other risks, of our key customers and vendors.
• We may be unable to pay future dividends.
• We may be unable to adequately protect our intellectual property, which may increase our cost of doing business or 

•

•

•

•

otherwise hurt our ability to compete in the market.
Changes in our credit profile 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.
Our business may suffer due to a departure of any of our key employees, a shortage of skilled labor or disruptions in 
our workforce.  A portion of our workforce is unionized, and any disruptions in our labor force or adverse employee 
relations could adversely affect our business.  
The market price of our common stock may fluctuate significantly, and the value of a stockholder’s investment could 
be impacted.
Compliance  with  and  changes  in  tax  laws  could  materially  and  adversely  impact  our  financial  condition,  results  of 
operations and cash flows.

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, 
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.

RISKS RELATED TO OUR BUSINESS

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, changes in consumer preferences 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, and more recently in response to the COVID-19 pandemic, 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, global market conditions, actions by foreign nations 
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.

Table of Content

We do not produce crude oil and must purchase all our crude oil, the price of which fluctuates based upon worldwide and local 
market conditions. Our profitability depends largely on the spread between market prices for refined petroleum products and 
crude oil prices. This margin is continually changing and may fluctuate significantly from time to time. Crude oil and refined 
products are commodities whose price levels are determined by market forces beyond our control. For example, the reversal of 
certain  existing  pipelines  or  the  construction  of  certain  new  pipelines  transporting  additional  crude  oil  or  refined  products  to 
markets  that  serve  competing  refineries  could  affect  the  market  dynamic  that  has  allowed  us  to  take  advantage  of  favorable 
pricing. 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, 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 charge and increase to cost of products sold in the amount of $78.5 million 
and a non-cash decrease to cost of products sold in the amount of $119.8 million for the years ended December 31, 2020 and 
2019, respectively.

To  successfully  operate  our  facilities,  we  are  required  to  expend  significant  amounts  for  capital  outlays  and  operating 
expenditures. If we are unable to complete capital projects at their expected costs or in a timely manner, 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.

Our facilities 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  facilities  by  installing  new 
equipment and redesigning older equipment to improve refinery capacity or to address changes in consumer preferences, such 
as the growing demand for renewable diesel and other lower carbon fuels. The installation and redesign of key equipment at our 
facilities,  including  the  conversion  of  our  Cheyenne  Refinery  to  renewable  diesel  production  and  the  construction  of  the 
renewable diesel and pre-treatment units at our Artesia facility, involves significant uncertainties, including the following: our 
upgraded  equipment  may  not  perform  at  expected  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 the third quarter of 2020, we permanently ceased 
refining  operations  at  our  Cheyenne  Refinery  and  subsequently  began  converting  certain  assets  at  the  Cheyenne  Refinery  to 
renewable diesel production due, in part, to uncompetitive operating and maintenance costs for the refinery.

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 conversion or expansion of existing ones, such as the conversion of 
the Cheyenne Refinery to renewable diesel production and the connection of a new renewable diesel and a pre-treatment unit at 
the  Navajo  Refinery.  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 take 
advantage of new government incentive programs, or maintain the operations of our existing assets. Additionally, our growth 
strategy  includes  projects  that  permit  access  to  new  and/or  more  profitable  markets,  including  the  growing  demand  for 
renewable  diesel  and  other  lower  carbon  fuels.  The  construction  process  involves  numerous  regulatory,  environmental, 
political, and legal uncertainties, most of which are not fully within our control, including: 

25

•

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, terrorists or cyberattacks, domestic vandalism 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, the construction of 
our previously announced renewable diesel units and pre-treatment unit at our Cheyenne and Artesia facilities 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 or renewable diesel 
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.

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.

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, global market conditions, actions 
by foreign nations and customer demand.

The  COVID-19  pandemic  or  any  other  widespread  outbreak  of  an  illness  or  pandemic  or  other  public  health  crisis,  and 
actions taken in response thereto, as well as certain developments in the global oil markets, have had and may continue to 
have a material adverse effect on our operations, business, financial condition and results of operations and cash flows. 

Our success depends on the demand for petroleum products such as transportation fuels and finished lubricant products, which 
is  largely  driven  by  the  conditions  of  local  and  worldwide  economies,  and  the  supply  of  crude  oil  and  other  feedstocks. 
COVID-19’s  spread  across  the  globe  and  governmental  actions  in  response  thereto  have  negatively  affected  worldwide 
economic  and  commercial  activity,  significantly  reduced  global  demand  for  oil,  gas  and  refined  products,  and  created 
significant  volatility  and  disruption  of  financial  and  commodity  markets  in  the  first  half  of  2020.  Other  factors  currently 
impacting crude oil supply include production levels implemented by OPEC members, other large oil producers such as Russia 
and domestic and Canadian oil producers. The oversupply of crude oil in the market has caused certain domestic and Canadian 
oil producers from whom we source crude oil to shut-in their production, which could impact our ability to readily source crude 
oil  once  the  stored  crude  oil  is  depleted.  While  demand  for  refined  products  stabilized  in  the  second  half  of  2020,  this 
combination of events contributed to an overall drop in prices, as well as a lack of forward visibility in demand, for crude oil 
and  refined  products  in  2020.  See  “Item  7,  Management's  Discussion  and  Analysis  of  Financial  Condition  and  Results  of 
Operations - Impact of COVID-19 on Our Business” for additional discussion of the impact of COVID-19 on our business. 

In addition, the supply and demand for refined and finished lubricant products depends on many other factors outside of our 
control, some of which include:

•

•
•

changes in domestic and international demand for, and the marketability of, our refined and finished lubricant products 
due to governmental actions, including travel bans and restrictions, quarantines, shelter in place orders, and shutdowns, 
which could result in a full or partial shutdown of our facilities;
increased price volatility, including the price we receive for refined and finished lubricant products;
the health of our workforce, including contractors and subcontractors, and their access to our facilities, which could 
result in a full or partial shutdown of our facilities if a significant portion of the workforce at a facility is impacted;

26

Table of Content

the availability, distribution and effectiveness of vaccines for COVID-19;
the ability or willingness of our vendors and suppliers to provide the equipment, parts, crude oil or other raw materials 
for our operations or otherwise fulfill their contractual obligations, which could reduce our production levels or 
otherwise cause our delay or failure to deliver refined or other finished lubricant products timely or at all or cause 
delay or failure to complete projects at our facilities;
the ability or willingness of our customers to fulfill their contractual obligations or any material reduction in, or loss of, 
revenue from our customers;
increased potential for the occurrence of operational hazards, including terrorism, cyberattacks or domestic vandalism, 
as well as information system failures or communication network disruptions;
increased cost and reduced availability of capital for growth or capital expenditures;
availability and operability of terminals, tankage and pipelines that store and transport crude oil and refined and 
finished lubricant products;
delay by government authorities in issuing or maintaining permits necessary for our business or our capital projects;
shareholder activism and activities by non-governmental organizations to limit sources of funding for the energy 
sector;
increased costs of operation in relation to the COVID-19 outbreak, which costs may not be fully recoverable or 
adequately covered by insurance; and
the impact of any economic downturn, recession or other disruption of the U.S. and global economies and financial 
and commodity markets.

The  spread  of  COVID-19  has  caused  us  to  significantly  modify  our  business  practices  (including  limiting  employee  and 
contractor presence at our work locations, restricting travel unless approved by senior leadership, quarantining employees when 
necessary, reducing our expected total consolidated capital expenditures for 2020 and reducing utilization at our refineries), and 
we may take further actions as may be required by government authorities or that we determine are in the best interests of our 
employees,  contractors,  customers,  suppliers  and  communities.  There  is  no  certainty  that  such  measures  will  be  sufficient  to 
mitigate  the  risks  posed  by  the  virus,  and  our  ability  to  perform  critical  functions  could  be  adversely  impacted.  In  addition, 
deterioration in gross margins and the economic slowdown resulting from the COVID-19 pandemic was a contributing factor in 
certain  goodwill  and  long-lived  asset  impairments  we  recorded  in  2020.  See  “An  impairment  of  our  goodwill  or  long-lived 
assets could reduce our earnings or negatively impact our financial condition and results of operations” for further discussion of 
the  impairment  risk  in  our  business  and  the  impairments  we  recorded  in  2020.  A  reasonable  expectation  exists  that  further 
deterioration in gross margins or a prolonged economic slowdown due to the COVID-19 pandemic could result in an additional 
impairment of assets or of goodwill at some point in the future. Such impairment charges could be material.

The effects of COVID-19 are difficult to predict and the duration of any potential business disruption or the extent to which it 
may negatively affect our operating results is uncertain. Any additional impact will depend on future developments and new 
information that may emerge regarding the spread, severity and duration of the COVID-19 pandemic and the actions taken by 
authorities to contain it or manage its impact, all of which are beyond our control. In addition, if the volatility and seasonality in 
the oil and gas industry were to increase, the demand for our products and the prices that we will be able to charge for those 
products may decline. We continue to monitor the situation to assess further possible implications to our business and to take 
actions in an effort to mitigate adverse consequences. The effects of the COVID-19 pandemic, as well as the volatility in global 
oil markets, while uncertain, have and may continue to, materially adversely affect our business, financial condition, results of 
operations and/or cash flows, as well as our ability to pay dividends to our shareholders.

Competition in the refining and marketing industry is intense, and an increase in competition in the markets in which we 
sell our products could adversely affect our earnings and profitability.

We compete with a broad range of refining and marketing companies, including certain multinational oil companies. Because of 
their  geographic  diversity,  larger  and  more  complex  refineries,  integrated  operations  and  greater  resources,  some  of  our 
competitors may be better able to withstand volatile market conditions, to obtain crude oil in times of shortage and to bear the 
economic risks inherent in all areas of the refining industry.

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

27

Table of Content

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.

The market for our lubricants and specialty products segment is highly competitive and requires us to continuously develop 
and introduce new products and product enhancements.

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.

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  El  Dorado,  Navajo,  Woods  Cross,  and  Tulsa  Refineries  are  NuStar  Energy  and  Magellan,  SFPP  and  Plains, 
Chevron and UNEV, and Magellan, respectively. 

Our U.S. 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 insurance (including business interruption) and casualty 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.

28

Table of Content

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. There are a limited number of crude oil suppliers in certain geographic regions, and in such cases, we may be required 
to source from a single third party supplier. If we are unable to maintain or extend our existing contracts with any such crude oil 
suppliers, or enter into new agreements on similar terms, the supply of crude oil could be adversely impacted, or we may incur 
a  higher  cost.  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,  catastrophic  events  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 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,  2020,  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  third  parties,  charging  fees  for  terminalling  refined  products  and  other  hydrocarbons  and  storing  and 
providing other services at its terminals. HEP serves the El Dorado, Navajo, Woods Cross and Tulsa Refineries under several 
long-term  pipeline  and  terminal,  tankage  and  throughput  agreements  expiring  in  2022  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.

While  we  own  a  57%  limited  partner  interest  and  a  non-economic  general  partner  interest  in  HEP,  HEP  is  a  publicly-traded 
master  limited  partnership  and  is  a  legally  distinct  entity.  Conflicts  of  interest  may  arise  between  us  and  HEP,  which  may 
subject us to claims from HEP's public unitholders.

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, 
2020.

Our acquisition strategy involves numerous risks, any of which could adversely affect us.

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.

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

An impairment of our goodwill or long-lived assets 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  goodwill  or  long-lived  asset  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 goodwill and long-lived assets 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 goodwill or long-lived assets 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,  2020,  we  recorded  long-lived  asset 
impairment  charges  of  $232.2  million  that  related  to  our  Cheyenne  Refinery,  $26.5  million  for  construction-in-progress 
consisting  primarily  of  engineering  work  for  potential  upgrades  to  certain  processing  units  at  our  Tulsa  and  El  Dorado 
Refineries  and  $204.7  million  related  to  PCLI.  Also,  during  the  year  ended  December  31,  2020,  we  recorded  a  goodwill 
impairment charge of $81.9 million that related to Sonneborn. A reasonable expectation exists that further deterioration in our 
operating results or overall economic conditions could result in an impairment of goodwill and / or additional long-lived asset 
impairments at some point in the future. Future impairment charges could be material to our results of operations and financial 
condition.

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.

We sell many of our lubricants and specialty products through distributors, which presents risks that could adversely affect 
our operating results.

A  large  portion  of  our  lubricants  and  specialty  product  sales,  both  in  domestic  and  international  markets,  occur  through 
distributors.  As  a  result,  we  are  dependent  on  these  distributors  to  promote  and  create  demand  for  our  products.  We  cannot 
assure you that we will be successful in maintaining and strengthening our relationships with our distributors or establishing 
relationships with new distributors who have the ability to market, sell and support our products effectively. We may rely on 
one or more key distributors for a product or a region, and the loss of these distributors could reduce our revenue. The sales, 
business  practices  and  reputation  of  our  distributors  may  affect  our  business  and  our  reputation.  The  consolidation  of 
distributors, loss of a relationship with a distributor, significant disagreement with a distributor, or significant deterioration in 
the  financial  condition  of  a  distributor  could  also  have  an  adverse  effect  on  our  operating  results  and  may  also  result  in 
increased competition in the applicable jurisdiction.

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.

RISKS RELATED TO GOVERNMENT REGULATION

There are various risks associated with greenhouse gases and climate change that could result in increased operating costs 
and litigation and reduced demand for the refined products we produce and investment in our industry. 

Climate change continues to attract considerable attention in the United States, Canada, Europe, and other regions. Numerous 
proposals have been made and could continue to be made at the international, national, regional and state levels of government 
to monitor and limit existing emissions of greenhouse gases, or “GHGs”, to restrict or eliminate such future emissions, and to 
require or incentivize the use of lower-carbon or renewable alternatives. As a result, our operations are subject to a series of 
regulatory, political, litigation, and financial risks associated with the refining of petroleum products and emission of GHGs.

The EPA has determined that emissions of carbon dioxide, methane and other GHGs present an endangerment to public health 
and  the  environment  because  emissions  of  such  gases  are,  according  to  the  EPA,  contributing  to  warming  of  the  earth's 
atmosphere  and  other  climatic  changes.  The  U.S.  Supreme  Court  has  also  found  that  GHG  emissions  constitute  a  pollutant 
under the CAA. Accordingly, the EPA has adopted rules that, among other things, establish construction and operating permit 
reviews  for  GHG  emissions  from  certain  large  stationary  sources,  require  the  monitoring  and  annual  reporting  of  GHG 
emissions  from  certain  petroleum  and  natural  gas  sources  in  the  United  States  or  to  control  or  reduce  emissions  of  GHGs, 
including methane, from such sources. In addition, the EPA, together with the DOT, implement GHG emission and corporate 
average  fuel  economy  standards  for  vehicles  manufactured  in  the  United  States.  Moreover,  on  January  27,  2021,  President 
Biden  issued  an  executive  order  that  commits  to  substantial  action  on  climate  change,  calling  for,  among  other  things,  the 
increased  use  of  zero-emissions  vehicles  by  the  federal  government,  the  elimination  of  subsidies  provided  to  the  fossil  fuel 
industry,  and  increased  emphasis  on  climate-related  risks  across  governmental  agencies  and  economic  sectors.  Additionally, 
various  states  and  groups  of  states  have  adopted  or  are  considering  adopting  legislation,  regulations  or  other  regulatory 
initiatives  that  are  focused  on  such  areas  as  GHG  cap  and  trade  programs,  carbon  taxes,  reporting  and  tracking  programs, 
restriction  of  emissions,  electric  vehicle  mandates  and  combustion  engine  phaseouts.  Similar  such  regulations  exist  at  the 
provincial and federal levels in Canada, including a nation-wide greenhouse gas pricing initiative and regulations related to the 
control of GHGs from automobiles and light duty trucks and either cap and trade programs or carbon taxes in the provinces of 
Quebec, Ontario, and Alberta. The Netherlands also participates in certain European legal initiatives, including GHG cap and 
trade programs, and the Climate Act with the goal of significantly reducing GHG emissions by 49% (compared to 1990) by 
2030 and by at least 95% (compared to 1990) by 2050.  The Climate Act also establishes that the government must prepare a 
Climate  Plan.  The  first  Climate  Plan  covers  the  period  between  2021  and  2030.  This  plan  contains,  amongst  others,  the 
principles by which the government intends to achieve the goals set out in the Climate Act. It is unclear what further measures 
the Dutch government will take to reduce GHG emissions pursuant to this law. At the international level, the United Nations-
sponsored “Paris Agreement” calls for member nations to limit their GHG emissions through nationally-determined reduction 
goals  reevaluated  every  five  years  after  2020.  The  United  States  initially  joined  and  then  withdrew  from  such  agreement, 
effective  November  4,  2020.  Under  the  new  administration,  the  United  States  rejoined  the  agreement  effective  February  19, 
2021 and has instructed the federal government to begin formulating the United States' emissions reduction goal. EU member 
states have agreed to reduce emissions by at least 40% by 2030. The Netherlands target is 49% reduction in GHG emissions by 
2030.

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. Additionally, political, litigation and financial risks may 
result in curtailed refinery activity, incurred liability, or other adverse effects on our business, financial condition and results of 
operations.

There are also increasing risks of litigation related to climate change effects. Governments and third-parties have brought suit 
against some fossil fuel companies alleging, among other things, that such companies created public and private nuisances by 
producing  fuels  that  contributed  to  climate  change,  such  as  rising  sea  levels,  and  therefore  are  responsible  for  roadway  and 
infrastructure damages as a result, or alleging that the companies have been aware of the adverse effects of climate change for 
some time but defrauded their investors or customers by failing to adequately disclose those impacts. While we are not party to 
such suits at this time, we may become subject to such litigation in the future. Such cases could also adversely impact public 
perception and the demand for fossil fuels and petroleum products, which could subsequently result in decreased demand for 
our services and refined products and a drop in our share price.

32

Table of Content

Our share price could be adversely impacted if existing shareholders, including institutional investors, elect in the future to shift 
some  or  all  of  their  investments  into  renewable  energy  or  non-energy  related  sectors  based  on  social  and  environmental 
considerations. Additionally, in recent years institutional lenders have become more attentive to sustainable lending practices 
and  have  been  lobbied  intensively,  and  often  publicly,  by  environmental  activists,  proponents  of  the  international  Paris 
Agreement,  and  foreign  citizenry  concerned  about  climate  change  not  to  provide  funding  for  fossil  fuel  energy  companies. 
Limitation of investments in and financings for fossil fuel energy companies could result in the restriction, delay or cancellation 
of  drilling  programs  or  development  or  production  activities,  could  result  in  a  reduction  of  available  capital  funding  for 
potential development projects and could also adversely affect demand for our services and refined products, all of which could 
impact our future financial results.

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 the past, we have received small refinery exemptions under the RFS program for certain of our refineries. However, there is 
no  assurance  that  such  an  exemption  will  be  obtained  for  any  of  our  refineries  in  future  years.  For  example,  the  EPA  has 
recently  indicated  it  plans  to  more  closely  align  the  agency’s  criteria  for  granting  small  refinery  exemptions  with  the 
recommendation of the Department of Energy, which could result in fewer such exemptions being granted. The failure to obtain 
such exemptions for certain of our refineries could result in the need to purchase more RINs than we currently have estimated 
and accrued for in our consolidated financial statements. EPA recently promulgated new RFS regulations that could require the 
agency to increase the volume of renewable fuel or RINs that refiners are required to purchase if the agency anticipates it will 
grant  small  refinery  exemptions.  This  also  could  increase  the  number  of  RINs  we  need  to  purchase.  Additionally,  a  recent 
decision  by  the  U.S.  Court  of  Appeals  for  the  10th  Circuit  vacated  two  small  refinery  exemption  decisions  for  the  2016 
compliance  year  and  remanded  the  case  to  the  EPA  for  further  proceedings.  That  decision  is  before  the  Supreme  Court  for 
further review.  It is not clear at this time what steps the EPA will take with respect to our 2016 small refinery exemptions, or 
how the case will impact future small refinery exemptions.

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, but the EPA does not always do 
so by the statutory deadline. Moreover, in addition to increased price volatility in the RINs 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.

33

Table of Content

We  incur  significant  costs,  and  expect  to  incur  additional  costs  in  the  future,  to  comply  with  existing,  new  and  changing 
environmental, energy, health and safety laws and regulations, and face potential exposure for environmental matters. 

Operations of our facilities and pipelines are subject to international, foreign, 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,  ship  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,  we  have  manufacturing  and  distribution  operations  in  foreign  countries  that  are 
subject to the environmental laws and regulations of such foreign countries. Permits or other authorizations are required under 
these laws for the operation of our facilities, 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, refinery shutdowns, and reputational harm. 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  and,  in  2018,  published  attainment/nonattainment  designations.  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.  In  November  2018,  the  EPA  published  amendments  to  the  new  rules  to  clarify  and  correct  certain 
requirements. These 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  processed,  manufactured,  handled, 
used, released or disposed.

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

Our operations are also subject to various foreign and domestic 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  or  courts  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.

34

Table of Content

We  are  also  subject  to  existing,  and  may  in  the  future  be  subject  to  new  or  changing,  domestic  and  foreign  energy  policy 
legislation. For example, in the United States, the Energy Independence and Security Act mandates annually increasing levels 
for  the  use  of  renewable  fuels  such  as  ethanol  and  increasing  energy  efficiency  goals,  among  other  steps.  Dutch  law  also 
focuses on increasing the use of renewal fuels, and in Canada, fuel content legislation 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.”

We are subject to significant regulation and oversight by governmental agencies.  

New  laws,  policies,  regulations,  rulemaking  and  oversight,  as  well  as  changes  to  those  currently  in  effect,  could  adversely 
impact our earnings, cash flows and operations. Our assets and operations are subject to regulation and oversight by foreign, 
federal, state and local regulatory authorities. Legislative changes, as well as regulatory actions taken by these agencies, have 
the potential to adversely affect our profitability. In addition, a certain degree of regulatory uncertainty is created by the new 
administration because it remains unclear specifically what the new administration may do with respect to future policies and 
regulations  that  may  affect  us.  Regulation  affects  almost  every  part  of  our  business.  Furthermore,  we  could  incur  additional 
costs to comply with such statutes, rules, regulations and orders.  Should we fail to comply with any applicable statutes, rules, 
regulations, and orders of regulatory authorities, we could be subject to substantial penalties and fines. New laws, regulations or 
policy  changes  sometimes  arise  from  unexpected  sources.  New  laws  or  regulations,  unexpected  policy  changes  or 
interpretations of existing laws or regulations, applicable to our income, operations, assets or another aspect of our business, 
could have a material adverse impact on our earnings, cash flow, financial condition and results of operations.

Our  business  is  subject  to  complex  and  evolving  global  laws,  regulations  and  security  standards  regarding  privacy, 
cybersecurity  and  data  protection  (“data  protection  laws”).  Many  of  these  laws  are  subject  to  change  and  uncertain 
interpretation, and could result in claims, increased cost of operations, or otherwise harm our business.  

The  constantly  evolving  regulatory  and  legislative  environment  surrounding  data  privacy  and  protection  poses  increasingly 
complex  compliance  challenges,  and  complying  with  such  data  protection  laws  could  increase  the  costs  and  complexity  of 
compliance.  While  we  do  not  collect  significant  amounts  of  personal  information  from  consumers,  we  do  have  personal 
information from our employees, job applicants and some business partners, such as contractors and distributors. Any failure, 
whether real or perceived, by us to comply with applicable data protection laws could result in proceedings or actions against us 
by  governmental  entities  or  others,  subject  us  to  significant  fines,  penalties,  judgments,  and  negative  publicity,  require  us  to 
change  our  business  practices,  increase  the  costs  and  complexity  of  compliance,  and  adversely  affect  our  business.  Our 
compliance with recently enacted laws like the General Data Protection Regulation, and other similar privacy/security laws, as 
well  as  any  associated  inquiries  or  investigations  or  any  other  government  actions  related  to  these  laws,  may  increase  our 
operating costs.

Increases  in  required  fuel  economy  and  regulation  of  CO2  emissions  from  motor  vehicles  may  reduce  demand  for 
transportation fuels. 

The  EPA  and  the  National  Highway  Traffic  Safety  Administration  (“NHTSA”)  are  required  to  promulgate  requirements 
regarding the Corporate Average Fuel Economy (“CAFE”) of the nation's passenger fleet. On August 28, 2012, the EPA and 
NHTSA adopted standards through model year 2025 in two phases. The first phase established 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.  However,  following  the 
change  in  presidential  administrations,  there  have  been  attempts  to  modify  these  standards.  In  August  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. While the EPA issued a rule in September 2019 that seeks to preempt the ability 
of  states  to  set  stricter  standards  than  those  set  by  the  federal  government,  no  final  rule  has  yet  been  issued  regarding 
amendments to the current CAFE standards. All of these rulemakings will likely be subject to challenge by a variety of parties 
seeking stricter GHG and CAFE standards. Additionally, several states are seeking to promote zero emission vehicles, such as 
electric vehicles, and to mandate transition away from internal combustion engines. Any increases in fuel economy standards, 
along with mandated increases in use of renewable fuels discussed above, as well as electric vehicle mandates or combustion 
engine  bans,  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.

GENERAL RISK FACTORS

Cyberattacks or security breaches could have a material adverse effect on our business, financial condition and results of 
operations.  

Our  business  is  dependent  upon  information  systems  and  other  digital  technologies  for  controlling  our  plants  and  pipelines, 
processing  transactions  and  summarizing  and  reporting  results  of  operations.  The  secure  processing,  maintenance  and 
transmission  of  information  is  critical  to  our  operations.  We  monitor  our  information  systems  on  a  24/7  basis  in  an  effort  to 
detect  cyberattacks  or  security  breaches.  Preventative  and  detective  measures  we  utilize  include  independent  cybersecurity 
audits  and  penetration  tests.  We  implemented  these  efforts  along  with  other  risk  mitigation  procedures  to  detect  and  address 
unauthorized and damaging activity on our network, stay abreast of the increasing threat landscape and improve our security 
posture. Information technology system failures, communications network disruptions (whether intentional by a third party or 
due to natural disaster), and security breaches could still impact equipment and software used to control plants and pipelines, 
resulting  in  improper  operation  of  our  assets,  potentially  including  delays  in  the  delivery  or  availability  of  our  customers’ 
products, contamination or degradation of the products we transport, store or distribute, or releases of hydrocarbon products and 
other damage to our facilities for which we could be held liable.

Furthermore,  we  collect  and  store  sensitive  data  in  the  ordinary  course  of  our  business,  including  personally  identifiable 
information of our employees as well as our proprietary business information and that of our customers, suppliers, investors and 
other stakeholders. Despite our security measures, our information systems may become the target of cyberattacks or security 
breaches  (including  employee  error,  malfeasance  or  other  breaches),  which  could  result  in  the  theft  or  loss  of  the  stored 
information,  misappropriation  of  assets,  disruption  of  transactions  and  reporting  functions,  our  ability  to  protect  customer  or 
company information and our financial reporting. Even with insurance coverage, a claim could be denied or coverage delayed. 
A  cyber-attack  or  security  breach  could  result  in  liability  under  data  privacy  laws,  regulatory  penalties,  damage  to  our 
reputation or a loss of consumer confidence in our products and services, or additional costs for remediation and modification 
or enhancement of our information systems to prevent future occurrences, all of which could have a material and adverse effect 
on our business, financial condition or 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,  terror  or  cyberattacks,  domestic  vandalism,  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 commercially 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.

There can be no assurance that insurance will cover all or any damages and losses resulting from these types of hazards. We are 
not  fully  insured  against  all  risks  to  our  business  and  therefore,  we  self-insure  certain  risks.  If  any  of  our  facilities  were  to 
experience  an  interruption  in  operations,  our  earnings  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.

We may be subject to information technology system failures, communications network disruptions and data breaches. 

We  depend  on  the  efficient  and  uninterrupted  operation  of  hardware  and  software  systems  and  infrastructure,  including  our 
operating,  communications  and  financial  reporting  systems.  These  systems  are  critical  in  meeting  customer  expectations, 
effectively tracking, maintaining and operating our equipment, directing and compensating our employees, and interfacing with 
our financial reporting system. We have implemented safeguards and other preventative measures to protect our systems and 
data, including sophisticated network security and internal control measures; however, our information technology systems and 
communications network, and those of our information technology and communication service providers, remain vulnerable to 
interruption by fire, earthquake, power loss, telecommunications failure, terrorist attacks, Internet failures, computer malware, 
cyberattacks, data breaches and other events unforeseen or generally beyond our control.

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.

Our business is subject to the risks of international operations, including currency fluctuations 

We  derive  a  portion  of  our  revenue  and  earnings  from  international  operations.  Our  acquisitions  of  Petro-Canada  Lubricants 
and Sonneborn have expanded our operations and sales in foreign countries and correspondingly may increase our exposure to 
foreign exchange risks. 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 revenue, competitiveness and cost of doing business, which could have a material adverse effect 
on our business, financial condition and results of operations.

In addition, compliance with applicable U.S. and foreign laws and regulations, such as import and export requirements, anti-
corruption laws, data privacy regulations and 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,  distributors  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.

In  addition,  global  market  risks,  actions  by  foreign  nations  and  other  international  conditions,  particularly  in  a  time  of 
increasing economic and global instability, may have a material adverse effect on our results and operations. The consequences 
of such uncertainty cannot be anticipated or quantified.

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, 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  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  domestic  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 and domestic vandalism 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, vandalism or war could also affect 
our ability to raise capital including our ability to repay or refinance debt.

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 is evaluated quarterly and 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.

We  may  be  unable  to  adequately  protect  our  intellectual  property,  which  may  increase  our  cost  of  doing  business  or 
otherwise hurt our ability to compete in the market.

We use intellectual property in the ordinary course of our business, including trademarks, trade secrets, copyrighted work and 
innovations,  some  of  which  is  material  to  our  business.  We  take  measures  to  identify  and  protect  our  intellectual  property 
through practices appropriate for securing and protecting exclusive rights in and to our intellectual property, including applying 
for registrations in the United States and in various foreign countries. 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 trademarks (or other marks 
likely  to  cause  confusion  among  our  consumers),  technologies,  products  and  processes.  In  addition,  the  laws  and/or  judicial 
systems and enforcement mechanisms of foreign countries in which we create, market and sell our products may afford little or 
no effective protection of our intellectual property. We may also be subject to infringement complaints from others challenging 
our use of a technology. We cannot guarantee that our efforts to enforce our intellectual property rights against unauthorized 
use and appropriation, or our efforts to defend against third party claims of infringement would be successful. These potential 
risks  to  our  intellectual  property  could  subject  us  to  increased  competition  and  negatively  impact  our  liquidity,  financial 
position and results of operations.

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 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  person  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.

39

Table of Content

A  portion  of  our  workforce  is  unionized,  and  any  disruptions  in  our  labor  force  or  adverse  employee  relations  could 
adversely affect our business.  

We depend on unionized labor for the operation of many of our facilities. As of December 31, 2020, approximately 29% of our 
employees were represented by labor unions under collective bargaining agreements with various expiration dates. In addition, 
employees who are not currently represented by labor unions may seek union representation in the future. We may not be able 
to  renegotiate  our  collective  bargaining  agreements  when  they  expire  on  satisfactory  terms  or  at  all.  If  we  are  unable  to 
renegotiate  our  collective  bargaining  agreements  when  they  expire,  any  work  stoppages  or  other  labor  disturbances  at  these 
facilities could have an adverse effect on our business, impact our ability to make distributions to our unitholders and payments 
of  our  debt  obligations,  and  increase  our  costs.  In  addition,  our  existing  labor  agreements  may  not  prevent  a  strike  or  work 
stoppage or other adverse employee relations event 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 global 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.

Compliance  with  and  changes  in  tax  laws  could  materially  and  adversely  impact  our  financial  condition,  results  of 
operations and cash flows.

We are subject to extensive tax liabilities, including federal and state income taxes and transactional taxes such as excise, sales 
and use, payroll, franchise, withholding and property taxes. New tax laws and regulations and changes in existing tax laws and 
regulations  could  result  in  increased  expenditures  by  us  for  tax  liabilities  in  the  future  and  could  materially  and  adversely 
impact our financial condition, results of operations and cash flows.

Additionally, many tax liabilities are subject to periodic audits by taxing authorities, and such audits could subject us to interest 
and penalties.

Item 1B.  Unresolved Staff Comments

We do not have any unresolved staff comments.

Item 3. Legal Proceedings

Commitment and Contingency Reserves

In the ordinary course of business, we may become party to legal, regulatory or administrative proceedings or governmental 
investigations, including environmental and other matters. Damages or penalties may be sought from us in some matters and 
certain  matters  may  require  years  to  resolve.  While  the  outcome  and  impact  of  these  proceedings  and  investigations  on  us 
cannot be predicted with certainty, based on advice of counsel and information currently available to us, management believes 
that the resolution of these proceedings and investigations through settlement or adverse judgment will not either individually 
or in the aggregate have a material adverse effect on our financial condition, results of operations or cash flows.

The environmental proceedings are reported 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 when a governmental 
authority  is  party  to  the  proceedings  and  such  proceedings  involve  potential  monetary  sanctions  that  we  reasonably  believe 
could  exceed  $300,000  or  more.   Certain  disclosures  made  under  the  SEC’s  prior  $100,000  threshold  will  remain  until  their 
resolution.

Environmental Matters

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  in  discussions  with  the  Wyoming  Department  of  Environmental 
Quality (“WDEQ”) and the United States Environmental Protection Agency (“EPA”) relating to alleged violations of air quality 
emission limitations and requirements related to operation of certain refinery units at the Cheyenne Refinery. 

Notices of Violations were issued by the WDEQ in late 2016 and 2018. On July 18, 2019, HFCR and the WDEQ entered into a 
consent  decree,  and  on  August  9,  2019,  HFCR  paid  penalties  in  the  amount  of  $117,000  related  to  alleged  violations  of  air 
quality limits that occurred during the second quarter of 2016 through the second quarter of 2017. Separately, on October 23, 
2019, HFCR received a Notice of Violation from the WDEQ for possible violations of air quality standards during the first and 
second quarters of 2019. HFCR and WDEQ have been in discussions to resolve WDEQ’s alleged violations of air quality limits 
that occurred during the third quarter of 2017 through calendar year 2019. The WDEQ and HFCR also previously agreed that 
the discussions would also include exceedances that occurred during the first quarter of 2020 through the cessation of petroleum 
refining operations at the Cheyenne Refinery in the third quarter of 2020. During a settlement conference on November 9, 2020, 
WDEQ proposed a settlement that would impose a penalty of $95,075 to resolve the alleged violations that occurred during the 
third quarter of 2017 through the date of the refinery shutdown. As part of the settlement process, on January 15, 2021, the State 
of  Wyoming  filed  a  complaint  with  the  Wyoming  District  Court  addressing  the  alleged  violations.  The  WDEQ  and  HFCR 
agreed on the terms of a consent decree to resolve the alleged violations, and on February 18, 2021, a Joint Motion for Entry of 
Consent Decree and the Consent Decree were filed with the Wyoming District Court. HFCR expects that the Wyoming District 
Court will enter the Consent Decree during the first quarter of 2021.

El Dorado
HollyFrontier  El  Dorado  Refining  LLC  (“HFEDR”)  has  been  engaged  in  discussions  with,  and  has  responded  to  document 
requests from, the EPA, the U.S. Department of Justice (“DOJ”) and the State of Kansas regarding alleged Clean Air Act civil 
violations  relating  to  flaring  devices  and  other  equipment  at  the  refinery.  Topics  of  the  discussions  included:  (a)  three 
information requests for activities beginning in January 2009, (b) Risk Management Program compliance issues relating to a 
November 2014 inspection and subsequent events, (c) a Notice of Violation issued by the EPA in August 2017, and (d) possible 
late reporting under the Emergency Planning and Community Right-to-Know Act for the release of sulfur dioxide and visible 
emissions from October 2018.

Some  of  the  foregoing  civil  investigations  resulted  from  fires  that  occurred  at  the  El  Dorado  Refinery  in  September  2017, 
October 2018 and March 2019. An employee fatality occurred during the September 2017 event. On May 28, 2020, HFEDR 
reached a settlement in the form of a proposed consent decree with the EPA, the DOJ, and the State of Kansas regarding the 
alleged Clean Air Act civil violations relating to flaring devices and other equipment at the refinery, as well as compliance with 
the Clean Air Act’s Risk Management Program (“RMP”).

The proposed consent decree was lodged with the U.S. District Court for the District of Kansas, and the 30-day public comment 
period ended on July 18, 2020. On July 27, 2020, the EPA, the DOJ and the State of Kansas filed their Unopposed Motion to 
enter the Consent Decree with the U.S. District Court for the District of Kansas, and on August 27, 2020, the consent decree 
was  entered  by  the  district  judge  and  became  effective.  Pursuant  to  the  consent  decree,  among  other  terms  and  conditions, 
HFEDR is required to complete certain projects, implement protocols regarding the examination of its fired heaters and conduct 
a third party RMP audit of certain of its processes. In addition, HFEDR is required to pay a civil penalty of $2 million to the 
United States and $2 million to the State of Kansas in two installments, the first half within 30 days of entry of the consent 
decree and the second within six months of entry of the consent decree. The initial payment of $1 million each was paid to the 
EPA  on  September  18,  2020  and  the  State  of  Kansas  on  September  22,  2020,  and  HFEDR  has  undertaken  several  of  the 
required  projects.  The  consent  decree  resolves  the  alleged  federal  and  state  civil  Clean  Air  Act  liability  for  penalties  and 
injunctive relief, other than potential civil penalties for RMP violations. Finally, as part of the settlement, a 2009 consent decree 
applicable to the refinery was terminated.

The  Occupational  Safety  and  Health  Administration  (“OSHA”)  conducted  investigations  into  both  the  September  2017  and 
March 2019 events identified above, and HFEDR settled the OSHA claims related to those investigations in 2018 and 2019, 
respectively. In April 2019, HFEDR became aware that the EPA also initiated a criminal investigation into one or more of the 
foregoing  events.  HFEDR  has  received  a  grand  jury  subpoena  requesting  certain  documents  be  provided  to  the  EPA  with 
respect to the September 2017 event. We are cooperating with this investigation.  

Tulsa
HollyFrontier Tulsa Refining LLC (“HFTR”) operates under two Consent Decrees with the EPA and the Oklahoma Department 
of Environmental Quality (“ODEQ”) for the East and West Refineries.  On April 3, 2019, the EPA notified HFTR of potential 
violations of the Consent Decrees. On December 1, 2020, ODEQ, on behalf of ODEQ and the EPA, issued two demand letters 
alleging violations under the Consent Decrees, which stemmed from inspections conducted by the EPA at the refineries from 
May 1 through 5, 2017, as well as from a review of the refineries’ records. The alleged violations included the failure to comply 
with applicable continuous emissions monitoring system (CEMS) requirements and exceedances of the hydrogen sulfide (H2S) 
emission  limits.  During  a  follow-up  conference  call  with  ODEQ,  on  January  6,  2021,  ODEQ  shared  its  stipulated  penalty 
amounts for alleged violations pursuant to the two Consent Decrees. HFTR submitted timely responses to the ODEQ demand 
letters on February 8, 2021. It is too soon to predict the outcome of this matter.

Woods Cross
HollyFrontier  Woods  Cross  Refining  LLC  (“HFWCR”)  operates  under  a  federal  consent  decree  with  the  EPA  and  the  Utah 
Department of Environmental Quality.  On November 3, 2020, HFWCR received a letter from the EPA identifying potential 
violations of HFWCR’s federal consent decree that occurred from calendar year 2015 through the date of the letter.  HFWCR 
provided a response letter to the EPA on December 3, 2020 disputing certain of the potential violations in the EPA's November 
3, 2020 letter, and HFWCR supplemented its response letter on February 5, 2021 with additional information. It is too soon to 
predict the outcome of this matter.

Federal Trade Commission

On July 23, 2019, the Federal Trade Commission (“FTC”) issued a Civil Investigative Demand and a related Subpoena Duces 
Tecum requesting we provide specified information relating to the Sonneborn acquisition that closed on February 1, 2019. 

We  cooperated  with  the  FTC  in  its  investigation.  On  December  2,  2020,  the  FTC  notified  us  that  no  further  action  was 
warranted, and it had closed the investigation.  

Renewable Fuel Standard

Various  subsidiaries  of  HollyFrontier  are  currently  intervenors  in  three  lawsuits  brought  by  renewable  fuel  interest  groups 
against the EPA in federal courts alleging violations of the Renewable Fuel Standard under the Clean Air Act and challenging 
the  EPA’s  handling  of  small  refinery  exemptions.  We  intervened  to  vigorously  defend  the  EPA’s  position  on  small  refinery 
exemptions because we believe the EPA correctly applied applicable law to the matters at issue.

On January 24, 2020, in the first of these lawsuits, the U.S. Court of Appeals for the Tenth Circuit vacated the small refinery 
exemptions granted to two of our refineries for 2016 and remanded the case to the EPA for further proceedings. On April 15, 
2020, the Tenth Circuit entered its mandate, remanding the matter back to the EPA. On September 4, 2020, various subsidiaries 
of HollyFrontier filed a Petition for a Writ of Certiorari with the U.S. Supreme Court appealing the Tenth Circuit decision. On 

42

Table of Content

January 8, 2021, the U.S. Supreme Court granted HollyFrontier’s petition. We anticipate decision from the Supreme Court in 
June 2021. We expect that we will not know what steps the EPA will take with respect to our 2016 small refinery exemptions or 
how the case will impact future small refinery exemptions until after the Supreme Court’s decision in this matter.

The second lawsuit is before the Tenth Circuit. The matter is fully briefed and remains pending before that court.

The third lawsuit is before the DC Circuit. Briefing of the issues before the court commenced on December 7, 2020; however, 
in  light  of  the  Supreme  Court’s  decision  to  hear  HollyFrontier’s  appeal  of  the  Tenth  Circuit  decision,  this  case  was  stayed 
pending a decision from the Supreme Court.

In December 2020, various subsidiaries of HollyFrontier also filed a petition for review in the DC Circuit challenging EPA’s 
denial  of  small  refinery  exemption  petitions  for  years  prior  to  2016.  The  petition  was  consolidated  with  petitions  from  eight 
other refining companies challenging the same decision. In light of the Supreme Court’s decision to hear HollyFrontier’s appeal 
of the Tenth Circuit decision, this case was stayed pending a decision from the Supreme Court.

Other

We  are  a  party  to  various  other  litigation  and  proceedings  that  we  believe,  based  on  advice  of  counsel,  will  not  either 
individually or in the aggregate have a materially adverse impact on our financial condition, results of operations or cash flows.

Securities 

Our common stock is traded on the New York Stock Exchange under the trading symbol “HFC.” 

In November 2019, our Board of Directors approved a $1.0 billion share repurchase program, which replaced all existing share 
repurchase programs. The timing and amount of stock repurchases will depend on market conditions and corporate, regulatory 
and  other  relevant  considerations.  We  do  not  intend  to  repurchase  common  stock  under  our  $1.0  billion  share  repurchase 
program  until  commodity  prices  and  demand  for  products  normalize.  This  program  may  be  discontinued  at  any  time  by  the 
Board of Directors. The following table includes repurchases made under this program during the fourth quarter of 2020.

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,  specialty  lubricant  products  and  specialty  and  modified  asphalt.  We  own  and  operate  refineries  located  in  Kansas, 
Oklahoma,  New  Mexico  and  Utah  and  market  our  refined  products  principally  in  the  Southwest  United  States,  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 United States, 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.

In the third quarter of 2020, we permanently ceased petroleum refining operations at our Cheyenne Refinery and subsequently 
began converting certain assets at our Cheyenne Refinery to renewable diesel production. This decision was primarily based on 
a positive outlook in the market for renewable diesel and the expectation that future free cash flow generation at our Cheyenne 
Refinery would be challenged due to lower gross margins resulting from the economic impact of the COVID-19 pandemic and 
compressed crude differentials due to dislocations in the crude oil market. Additional factors included uncompetitive operating 
and maintenance costs forecasted for our Cheyenne Refinery and the anticipated loss of the EPA’s small refinery exemption. 
The renewable diesel units are expected to be completed in the first quarter of 2022 with an expected capital budget between 
$125-$175 million. 

During the second quarter of 2020, we recorded long-lived asset impairment charges of $232.2 million related to our Cheyenne 
Refinery  asset  group.  In  connection  with  the  cessation  of  petroleum  refining  operations  at  our  Cheyenne  Refinery,  we 
recognized $24.7 million in decommissioning expense for the year ended December 31, 2020. In addition, for the year ended 
December  31,  2020,  we  recorded  a  reserve  of  $9.0  million  against  our  repair  and  maintenance  supplies  inventory  and  $3.8 
million in employee severance costs related to the conversion of our Cheyenne Refinery to renewable diesel production. These 
decommissioning, inventory reserve and severance costs were recognized in operating expenses, of which $24.8 million was 
recorded in our Refining segment and $12.7 million was recorded in our Corporate and Other segment.

During  the  second  quarter  of  2020,  we  also  initiated  and  completed  a  corporate  restructuring,  which  is  expected  to  save 
approximately  $30  million  per  year  of  ongoing  cash  expenses.  As  a  result  of  this  restructuring,  we  recorded  $3.7  million  in 
employee severance costs, which were recognized primarily as operating expenses in our Refining segment and selling, general 
and administrative expenses in our Corporate and Other segment.

During the first quarter of 2021, we initiated a restructuring within our Lubricants and Specialty Products segment, which is 
expected to save approximately $15 million per year of ongoing cash expenses. Over the next twelve months, we anticipate pre-
tax costs of $8 -$10 million for severance obligations.

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 $662.7 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 and Wyoming, along with a blending and packaging facility in Texas.

For the year ended December 31, 2020, net loss attributable to HollyFrontier stockholders was $(601.4) million compared to net 
income of $772.4 million and $1,098.0 million for the years ended December 31, 2019, and 2018, respectively. Overall gross 
refining margins per produced barrel sold for 2020 decreased 54% over the year ended December 31, 2019 due to lower crack 
spreads and crude oil basis differentials. Included in our financial results for the year ended December 31, 2020 were  non-cash 
items consisting of goodwill and long-lived asset impairment charges.

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 
$148.5 million for the year ended December 31, 2020.

Impact of COVID-19 on Our Business
The  COVID-19  pandemic  caused  a  decline  in  U.S.  and  global  economic  activity  starting  in  the  first  quarter  of  2020.  This 
decrease  reduced  both  volumes  and  unit  margins  across  our  businesses,  resulting  in  lower  gross  margins  and  earnings. 
Following a rebound in the late second and third quarters, demand for transportation fuels continued to be weak compared to 
2019. In response to this level of demand, during the fourth quarter of 2020, we operated our Refining segment refineries at an 
average crude charge of 379,910 BPD.

In our Lubricants and Specialty Products segment, the Rack Forward portion saw improvement in industrial and transportation-
related  end  markets,  which  drove  higher  demand  and  unit  margins  during  the  second  half  of  2020.  Within  the  Rack  Back 
portion, demand for base oils increased to 2019 levels while supply was limited due to a number of factors, which drove higher 
margins and utilization at our facilities in the third quarter.

The  stabilization  of  demand  drove  a  broad  increase  in  commodity  prices,  resulting  in  values  for  our  inventories  held  at 
December 31, 2020 above the costs of these inventories using the last-in, first-out (“LIFO”) method and in a lower of cost or 
market valuation gain of $149.2 million for the three months ended December 31, 2020. We also drew down on our inventory 
levels  to  better  manage  working  capital  in  the  fourth  quarter  of  2020,  which  resulted  in  a  $35  million  increase  in  cost  of 
products sold for the quarter.

Our standalone (excluding HEP) liquidity was approximately $2,696.3 million at December 31, 2020, consisting of cash and 
cash equivalents of $1,346.3 million and an undrawn $1.35 billion credit facility maturing in 2022. Our standalone (excluding 
HEP) long-term debt was $1.75 billion as of December 31, 2020, which consists of $350.0 million in 2.625% senior notes due 
in 2023, $1.0 billion of 5.875% senior notes due in 2026 and $400.0 million in 4.500% senior notes due in 2030.

OUTLOOK 

The impact of the COVID-19 pandemic on the global macroeconomy created an unprecedented reduction in demand in the first 
half of 2020, as well as a lack of forward visibility, for many of the transportation fuels, lubricants and specialty products and 
the associated transportation and terminal services we provide. We have seen improvement in demand for these products and 
services since the initial wave of COVID-19 infections during the second quarter of 2020, and with the increasing availability 
of vaccines, we believe there is a path to a fulsome recovery in demand in 2021. 

In response to the COVID-19 pandemic, and with the health and safety of our employees as a top priority, we continue a range 
of  initiatives,  including  limiting  onsite  staff  at  all  of  our  facilities,  implementing  a  work-from-home  policy  for  certain 
employees and restricting travel unless approved by senior leadership. We will continue to monitor COVID-19 developments 
and the dynamic environment to properly address these policies going forward.

Within our Refining segment, for the first quarter of 2021, we expect to run between 350,000-380,000 barrels per day of crude 
oil. In addition to continued weakness in demand resulting from the COVID-19 pandemic, the crude charge in the first quarter 
of 2021 has also been adversely impacted by scheduled maintenance at our Tulsa West and Woods Cross refineries as well as 
reduced availability, and an increase in the price, of natural gas due to the recent extreme cold weather throughout the Mid-
Continent and Southwest. We expect to adjust refinery production levels commensurate with market demand.

Within  our  Lubricants  and  Specialty  Products  segment,  we  expect  a  normal  seasonal  rebound  in  the  first  quarter  of  2021. 
However, we do not have enough visibility to issue forward guidance at this time. Similar to our Refining segment, we expect 
to adjust production levels commensurate with market demand.

Table of Content

At  HEP,  we  expect  to  see  demand  for  transportation  and  terminal  services  grow  with  underlying  demand  for  transportation 
fuels and crude oil. In 2021, HEP expects to hold the quarterly distribution constant at $0.35 per unit, or $1.40 on an annualized 
basis. HEP remains committed to its distribution strategy focused on funding all capital expenditures and distributions within 
free  cash  flow  and  maintaining  distributable  cash  flow  coverage  of  1.3x  or  greater  with  the  goal  of  reducing  leverage  to 
3.0-3.5x.

During the third quarter of 2020, we increased our liquidity by $750.0 million with the issuance of $350.0 million in 2.625% 
senior  notes  due  in  2023  and  $400.0  million  in  4.500%  senior  notes  due  in  2030.  This  additional  liquidity  may  be  used  for 
general  corporate  purposes  and  is  expected  to  support  the  planned  growth  of  our  renewables  business  and  the  unexpected 
economic  impact  of  COVID-19,  as  needed.  We  do  not  intend  to  repurchase  common  stock  under  our  $1.0  billion  share 
repurchase program until demand for our products normalize.

On March 27, 2020, the U.S. government passed the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), 
an  approximately  $2  trillion  stimulus  package  that  includes  various  provisions  intended  to  provide  relief  to  individuals  and 
businesses in the form of tax changes, loans and grants, among others. At this time, we have not sought relief in the form of 
loans or grants from the CARES Act; however, we have benefited from certain tax deferrals in the CARES Act and may benefit 
from other tax provisions if we meet the requirements to do so. We anticipate $50.0 million to $60.0 million in cash tax benefit 
in 2021 from the loss carryback potential under the CARES Act. As a result of the net operating loss incurred in the year ended 
December 31, 2020, we will also file refund claims of approximately $21.0 million to recover estimated tax payments made 
during the year.

The  extent  to  which  our  future  results  are  affected  by  the  COVID-19  pandemic  will  depend  on  various  factors  and 
consequences  beyond  our  control,  such  as  the  duration  and  scope  of  the  pandemic,  additional  actions  by  businesses  and 
governments  in  response  to  the  pandemic  and  the  speed  and  effectiveness  of  responses  to  combat  the  virus.  The  COVID-19 
pandemic,  and  the  volatile  regional  and  global  economic  conditions  stemming  from  it,  could  also  exacerbate  the  risk  factors 
identified in this Form 10-K under “Risk Factors” in Item 1A. The COVID-19 pandemic may also materially adversely affect 
our results in a manner that is either not currently known or that we do not currently consider to be a significant risk to our 
business.

A more detailed discussion of our financial and operating results for the years ended December 31, 2020 and 2019 is presented 
in  the  following  sections.  Discussions  of  year-over-year  comparisons  for  2019  and  2018  can  be  found  in  “Management's 
Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of our Annual Report on Form 10-
K for the year ended December 31, 2019.

(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  and  Woods  Cross  Refineries.  The  following  tables  set  forth 
information,  including  non-GAAP  performance  measures,  about  our  consolidated  refinery  operations,  which  has  been 
retrospectively adjusted to reflect the revised regional groupings upon the Cheyenne Refinery permanently ceasing petroleum 
refining  operations  in  the  third  quarter  of  2020.  The  cost  of  products  and  refinery  gross  and  net  operating  margins  do  not 
include the non-cash effects of long-lived asset impairment charges, lower of cost or market inventory valuation adjustments 
and  depreciation  and  amortization.  Reconciliations  to  amounts  reported  under  GAAP  are  provided  under  “Reconciliations  to 
Amounts Reported Under Generally Accepted Accounting Principles” following Item 7A of Part II of this Form 10-K.

Results of Operations - Year Ended December 31, 2020 Compared to Year Ended December 31, 2019 

Summary
Net  loss  attributable  to  HollyFrontier  stockholders  for  the  year  ended  December  31,  2020  was  $(601.4)  million  ($(3.72)  per 
basic and diluted share), a $1,373.8 million decrease compared to net income of $772.4 million ($4.64 per basic and $4.61 per 
diluted share) for the year ended December 31, 2019. Net income decreased due principally to long-lived asset and goodwill 
impairment charges of $545.3 million offset by an $81.0 million gain recognized upon the settlement of a business interruption 
insurance claim. In addition, net income decreased as a result of lower gross refining margins and lower refining segment sales 
volumes.  For  the  year  ended  December  31,  2020,  lower  of  cost  or  market  inventory  reserve  adjustments  decreased  pre-tax 
earnings  by  $78.5  million  compared  to  an  increase  of  $119.8  million  for  the  year  ended  December  31,  2019.  Refinery  gross 
margins  for  the  year  ended  December  31,  2020  decreased  to  $7.29  per  produced  barrel  from  $15.92  for  the  year  ended 
December 31, 2019. The year ended December 31, 2019 included a goodwill impairment charge of $152.7 million. 

Sales and Other Revenues
Sales and other revenues decreased 36% from $17,486.6 million for the year ended December 31, 2019 to $11,183.6 million for 
the year ended December 31, 2020 due to a year-over-year decrease in sales prices and lower refined product sales volumes. 
Sales  and  other  revenues  for  the  years  ended  December  31,  2020  and  2019  include  $98.0  million  and  $121.0  million, 
respectively, in HEP revenues attributable to pipeline and transportation services provided to unaffiliated parties. Additionally, 
sales and other revenues included $1,792.7 million and $2,081.2 million in unaffiliated revenues related to our Lubricants and 
Specialty Products segment for the years ended December 31, 2020 and 2019, respectively. 

Cost of Products Sold
Total cost of products sold decreased 33% from $13,798.6 million for the year ended December 31, 2019 to $9,237.3 million 
for  the  year  ended  December  31,  2020,  due  principally  to  lower  crude  oil  costs  and  lower  refined  product  sales  volumes. 
Additionally, for the year ended December 31, 2020, we recognized a $78.5 million lower of cost or market inventory valuation 
charge compared to a benefit of $119.8 million for the same period of 2019, resulting in a new $318.9 million inventory reserve 
at December 31, 2020. The lower of cost or market reserve at December 31, 2020 is based on market conditions and prices at 
that  time.  During  the  year  ended  December  31,  2019,  we  recorded  a  $36.6  million  RINs  cost  reduction  as  a  result  of  our 
Cheyenne Refinery and Woods Cross Refinery small refinery exemptions. Also, during the year ended December 31, 2019, we 
recorded an $18.0 million reduction to cost of products sold as a result of U.S. blender's tax credit legislation that was signed in 
December 2019 and applied retroactively for the years 2019 and 2018.

Gross Refinery Margins
Gross refinery margin per barrel sold decreased 54% from $15.92 for the year ended December 31, 2019 to $7.29 for the year 
ended December 31, 2020. This was due to a decrease in the average per barrel sold sales price during the current year period, 
partially  offset  by  decreased  crude  oil  and  feedstock  prices.  Gross  refinery  margin  per  barrel  does  not  include  the  non-cash 
effects  of  lower  of  cost  or  market  inventory  valuation  adjustments,  long-lived  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  7%  from  $1,394.1  million  for  the  year  ended 
December 31, 2019 to $1,300.3 million for the year ended December 31, 2020 due principally to lower repair and maintenance 
costs primarily related to the shutdown of our Cheyenne Refinery, partially offset by decommissioning costs associated with the 
Cheyenne  Refinery  shutdown  recorded  in  the  year  ended  December  31,  2020.  Prior  year  period  operating  expenses  included 
higher repair and maintenance costs related to a February 2019 fire in an FCC unit at our El Dorado Refinery. 

Selling, General and Administrative Expenses
Selling,  general  and  administrative  expenses  decreased  11%  from  $354.2  million  for  the  year  ended  December  31,  2019  to 
$313.6  million  for  the  year  ended  December  31,  2020  due  principally  to  lower  professional  services  and  employee-related 
expenses.  We  incurred  $2.0  million  and  $24.2  million  in  direct  acquisition  and  integration  costs  for  our  Sonneborn  business 
during the years ended December 31, 2020 and 2019.

Depreciation and Amortization Expenses
Depreciation and amortization increased 2% from $509.9 million for the year ended December 31, 2019 to $520.9 million for 
the  year  ended  December  31,  2020.  This  increase  was  due  principally  to  depreciation  and  amortization  attributable  to 
capitalized  improvement  projects  and  capitalized  refinery  turnaround  costs,  partially  offset  by  lower  depreciation  expense 
resulting from the assets impaired in the current year period.

Goodwill and Long-lived Asset Impairments
During the year ended December 31, 2020, we recorded long-lived asset impairment charges of $232.2 million that related to 
our  Cheyenne  Refinery,  $26.5  million  for  construction-in-progress  consisting  primarily  of  engineering  work  for  potential 
upgrades to certain processing units at our Tulsa and El Dorado Refineries and $204.7 million related to PCLI. Also, during the 
year ended December 31, 2020, we recorded a goodwill impairment charge of $81.9 million that related to Sonneborn. During 
the year ended December 31, 2019 we recorded a goodwill impairment charge of $152.7 million that related to PCLI. See Note 
11 “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,  2020  was  $7.6  million  compared  to  $22.1  million  for  the  year  ended 
December 31, 2019. This decrease was primarily due to lower interest rates on cash investments.

Interest Expense
Interest  expense  was  $126.5  million  for  the  year  ended  December  31,  2020  compared  to  $143.3  million  for  the  year  ended 
December  31,  2019.  This  decrease  was  primarily  due  to  lower  market  interest  rates  on  HEP’s  credit  facility  and  HEP’s 
refinancing  of  its  6.0%  senior  notes  due  2024,  partially  offset  by  interest  expense  on  our  senior  notes  issued  in  2020. 
Additionally, we recorded unrealized losses on the mark-to-market change in the fair value of the embedded derivative in our 
catalyst financing arrangements of $4.3 million for the year ended December 31, 2020 and $6.4 million for the same period in 
2019.  For  the  years  ended  December  31,  2020  and  2019,  interest  expense  included  $52.9  million  and  $74.8  million, 
respectively, in interest costs attributable to HEP operations.

Gain on Business Interruption Insurance Settlement
During the year ended December 31, 2020, we recorded a gain of $81.0 million upon the settlement of our business interruption 
claim with our insurance carrier related to a loss at our Woods Cross Refinery that occurred in the first quarter of 2018.

Gain on Sales-type Leases
During the second quarter of 2020, HEP and Delek US Holdings, Inc. renewed the original throughput agreement on specific 
HEP assets. Portions of the new throughput agreement meet the definition of sales-type leases, which resulted in an accounting 
gain of $33.8 million upon the initial recognition of the sales-type lease during the year ended December 31, 2020.

Loss on Early Extinguishment of Debt
For  the  year  ended  December  31,  2020,  HEP  recorded  a  $25.9  million  loss  on  the  redemption  of  its  $500  million  aggregate 
principal amount of 6.0% senior notes maturing August 2024 at a redemption cost of $522.5 million.

Gain on Foreign Currency Transactions
Remeasurement  adjustments  resulting  from  the  foreign  currency  conversion  of  the  intercompany  financing  notes  payable  by 
PCLI  net  of  mark-to-market  valuations  on  foreign  exchange  forward  contracts  with  banks  which  hedge  the  foreign  currency 
exposure on these intercompany notes were gains of $2.2 million and $5.4 million for the years ended December 31, 2020 and 
2019, respectively. For the years ended December 31, 2020 and 2019, gain on foreign currency transactions included losses of 
$7.3 million and $17.4 million, respectively, on foreign exchange forward contracts (utilized as an economic hedge).

Income Taxes
For the year ended December 31, 2020, we recorded an income tax benefit of $232.1 million compared to income tax expense 
of $299.2 million for the year ended December 31, 2019. This decrease was due principally to a pre-tax loss during the year 
ended December 31, 2020 compared to pre-tax earnings for the year ended December 31, 2019. Our effective tax rates were 
31.1% and 25.5% for the years ended December 31, 2020 and 2019, respectively. The year-over-year increase in the effective 
tax  rate  is  due  principally  to  the  relationship  between  the  pre-tax  results  and  the  earnings  attributable  to  the  noncontrolling 
interest that is not included in income for tax purposes and benefits related to the CARES Act.

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, 2020, we were in compliance with all covenants, had 
no outstanding borrowings and had outstanding letters of credit totaling $5.7 million under the HollyFrontier Credit Agreement.

HollyFrontier Senior Notes
On  September  28,  2020,  we  completed  a  public  offering  of  $350.0  million  in  aggregate  principal  amount  of  2.625%  senior 
notes maturing October 2023 and $400.0 million in aggregate principal amount of 4.500% senior notes maturing October 2030. 
We intend to use the net proceeds for general corporate purposes, which may include capital expenditures. These 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.  The  leases  mature  on  February  1, 
2022. Upon maturity, we must either satisfy the obligation at fair market value or refinance to extend the maturity.

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, 2020, HEP received advances totaling $258.5 million and repaid $310.5 million under the 
HEP Credit Agreement. At December 31, 2020, HEP was in compliance with all of its covenants, had outstanding borrowings 
of $913.5 million and no outstanding letters of credit under the HEP Credit Agreement.

HEP Senior Notes
On  February  4,  2020,  HEP  closed  a  private  placement  of  $500.0  million  in  aggregate  principal  amount  of  5.0%  HEP  senior 
unsecured notes maturing February 2028. On February 5, 2020, HEP redeemed its existing $500.0 million aggregate principal 
amount of 6.0% senior notes maturing August 2024 at a redemption cost of $522.5 million. HEP recognized a $25.9 million 
early extinguishment loss consisting of a $22.5 million debt redemption premium and unamortized discount and financing costs 
of  $3.4  million.  HEP  funded  the  $522.5  million  redemption  with  proceeds  from  the  issuance  of  its  5.0%  senior  notes  and 
borrowings under the HEP Credit Agreement.

See Note 13 “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,  2020,  HEP  did  not  issue  any  common  units  under  this  program.  As  of  December  31,  2020,  HEP  has  issued 
2,413,153 common units under this program, providing $82.3 million in gross proceeds.

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. We expect that, to the extent necessary, we can raise additional funds from time to time through equity or 
debt  financings  in  the  public  and  private  capital  markets.  In  addition,  subject  to  our  current  cash  conservation  strategies  as 
discussed above in “Outlook,” 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. We also 
expect to use cash for payment of cash dividends, which are at the discretion of our Board of Directors, and, once commodity 
prices and demand for products normalize, for the repurchases of our common stock under our share repurchase program.

Our standalone (excluding HEP) liquidity was approximately $2.70 billion at December 31, 2020, consisting of cash and cash 
equivalents of $1.35 billion and an undrawn $1.35 billion credit facility. 

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 November 2019, our Board of Directors approved a $1.0 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, 2020, 
we had not repurchased common stock 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.  We  do  not 
intend to repurchase common stock under our $1.0 billion share repurchase program until commodity prices and demand for 
products normalize.

Cash and cash equivalents increased $483.2 million for the year ended December 31, 2020. Net cash provided by operating and 
financing  activities  of  $457.9  million  and  $353.2  million,  respectively,  exceeded  cash  used  for  investing  activities  of  $330.2 
million for the year ended December 31, 2020.

Cash Flows – Operating Activities

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019 
Net  cash  flows  provided  by  operating  activities  were  $457.9  million  for  the  year  ended  December  31,  2020  compared  to 
$1,548.6  million  for  the  year  ended  December  31,  2019,  a  decrease  of  $1,090.7  million.  Net  loss  for  the  year  ended 
December 31, 2020 was $514.9 million, a decrease of $1,387.3 million compared to net income of $872.4 million for the year 
ended December 31, 2019. Non-cash adjustments to net income / loss consisting of depreciation and amortization, goodwill and 
long-lived asset impairments, lower of cost or market inventory valuation adjustment, earnings of equity method investments, 
inclusive of distributions, loss on early extinguishment of debt, gain on sales-type leases, gain / loss on sale of assets, deferred 
income taxes, equity-based compensation expense and fair value changes to derivative instruments totaled $1,019.1 million for 
the  year  ended  December  31,  2020  compared  to  $700.5  million  for  the  same  period  in  2019.  Adjusted  for  non-cash  items, 
changes  in  working  capital  increased  operating  cash  flows  by  $43.5  million  and  $312.8  million  for  the  years  ended 
December  31,  2020  and  2019,  respectively.  Additionally,  for  the  year  ended  December  31,  2020,  turnaround  expenditures 
decreased to $94.7 million from $318.4 million for the same period of 2019.

Cash Flows – Investing Activities and Planned Capital Expenditures

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019 
Net  cash  flows  used  for  investing  activities  were  $330.2  million  for  the  year  ended  December  31,  2020  compared  to  $972.9 
million for the year ended December 31, 2019, a decrease of $642.8 million, primarily driven by prior year investing activity 
reflecting the acquisition of Sonneborn for a net cash outflow of $662.7 million. Cash expenditures for properties, plants and 
equipment for 2020 increased to $330.2 million from $293.8 million for the same period in 2019. These include HEP capital 
expenditures of $59.3 million and $30.1 million for the years ended December 31, 2020 and 2019, respectively. Additionally, 
HEP  invested  $2.4  million  and  $17.9  million  in  the  Cushing  Connect  Pipeline  &  Terminal  LLC  joint  venture  for  the  years 
ending December 31, 2020 and 2019, respectively. 

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. Refinery turnaround spending is amortized over the useful life of the turnaround.

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 renewable diesel, 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.  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.

Expected capital and turnaround cash spending for 2021 is as follows:

Cash Flows – Financing Activities

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019 
Net cash flows provided by financing activities were $353.2 million for the year ended December 31, 2020 compared to net 
cash  flows  used  for  financing  activities  of  $848.3  million  for  the  year  ended  December  31,  2019,  an  increase  of  $1,201.5 
million. During the year ended December 31, 2020, we received $742.1 million in net proceeds from the issuance of HFC’s 
2.625% and 4.500% senior notes, purchased $7.6 million of treasury stock and paid $229.5 million in dividends. Also during 
this period, HEP received $258.5 million and repaid $310.5 million under the HEP Credit Agreement, paid $522.5 million upon 
the redemption of HEP’s 6.0% senior notes and received $491.3 million in net proceeds from the issuance of HEP 5.0% senior 
notes, paid distributions of $89.0 million to noncontrolling interests and received contributions from noncontrolling interests of 
$23.9  million.  During  the  year  ended  December  31,  2019,  we  purchased  $533.1  million  of  treasury  stock  and  paid  $225.2 
million  in  dividends.  Also  during  2019,  HEP  received  $365.5  million  and  repaid  $323.0  million  under  the  HEP  Credit 
Agreement,  paid  distributions  of  $132.3  million  to  noncontrolling  interests  and  received  a  contribution  of  $3.2  million  from 
noncontrolling interests.

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, 2020 and 2019, market values had fallen 
below  historical  LIFO  inventory  costs  and,  as  a  result,  we  recorded  lower  of  cost  or  market  inventory  valuation  reserves  of 
$318.9 million and $240.4 million, respectively.

At December 31, 2020, our lower of cost or market inventory valuation reserve was $318.9 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.

Inventories consisting of process chemicals, materials and maintenance supplies and RINs are stated at the lower of weighted-
average  cost  or  net  realizable  value.  Inventories  of  our  Petro-Canada  Lubricants  and  Sonneborn  businesses  are  stated  at  the 
lower of cost, using the FIFO method, or net realizable value.

In connection with our announcement of the conversion of our Cheyenne Refinery to renewable diesel production, we recorded 
a reserve of $9.0 million for the year ended December 31, 2020 against our repair and maintenance supplies inventory.

Goodwill and Long-lived Assets
As  of  December  31,  2020,  our  goodwill  balance  was  $2.3  billion,  with  goodwill  assigned  to  our  Refining,  Lubricants  and 
Specialty  Products  and  HEP  segments  of  $1,733.5  million,  $247.6  million  and  $312.9  million,  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 either a quantitative assessment or an optional qualitative assessment to determine whether it is more likely than not that 
the fair value of a reporting unit is less than its carrying amount. If we determine that based on the qualitative factors that it is 
more likely than not that the carrying value of the reporting unit is greater than its fair value, a quantitative test is performed in 
which we estimate the fair value of the related reporting unit. If the carrying amount of a reporting unit exceeds its fair value, 
the goodwill of that reporting unit is impaired, and we measure goodwill impairment as the excess of the carrying amount of 
reporting unit over the related fair value.

For purposes of long-lived asset impairment evaluation, we have grouped our long-lived assets as follows: (i) our refinery asset 
groups, which include certain HEP logistics assets, (ii) our Lubricants and Specialty Products asset groups and (iii) our HEP 
asset groups, which comprises HEP assets not included in our refinery asset groups. These asset groups represent the lowest 
level  for  which  independent  cash  flows  can  be  identified.  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.

Goodwill and long-lived asset impairments 
During the second quarter of 2020, we determined that indicators of potential goodwill and long-lived asset impairments were 
present and performed recoverability testing for long-lived assets and an interim test for goodwill impairment as of May 31, 
2020.  Impairment  indicators  included  the  recent  economic  slowdown  caused  by  the  COVID-19  pandemic,  reductions  in  the 
prices of our finished goods and raw materials and the related decrease in our gross margins, as well as the recent decline in our 
market capitalization. Additionally, our second quarter announcement of the planned conversion of our Cheyenne Refinery to 
renewable  diesel  production  was  also  considered  a  triggering  event  requiring  assessment  of  potential  impairments  to  the 
carrying value of our Cheyenne Refinery asset group. As a result of our long-lived asset recoverability testing, we determined 
that the carrying value of the long-lived assets of our Cheyenne Refinery and PCLI asset groups were not recoverable, and thus 
recorded long-lived asset impairment charges of $232.2 million and $204.7 million, respectively, in the second quarter of 2020. 
Our interim goodwill impairment testing indicated that there was no impairment of goodwill at our Refining and Lubricants and 
Specialty  Products  reporting  units  as  of  May  31,  2020.  The  estimated  fair  values  of  the  Cheyenne  Refinery  and  PCLI  asset 
groups  were  determined  using  a  combination  of  the  income  and  cost  approaches.  The  income  approach  was  based  on 
management’s  best  estimates  of  the  expected  future  cash  flows  over  the  remaining  useful  life  of  the  asset  group.  The  cost 
approach  utilized  assumptions  for  the  current  replacement  costs  of  similar  assets  adjusted  for  estimated  depreciation  and 
economic obsolescence.

Table of Content

As  of  July  1,  2020,  we  performed  our  annual  goodwill  impairment  testing  quantitatively  and  determined  there  was  no 
impairment of goodwill attributable to our reporting units at that time. The excess of the fair values of the reporting units over 
their respective carrying values ranged from 10% to 229%. Increasing the discount rate by 1.0% or reducing the terminal cash 
flow growth rate by 1.0% would not have changed the results of our goodwill impairment testing performed in the second and 
third quarters of 2020. 

During  the  fourth  quarter  of  2020,  we  incurred  long-lived  asset  impairment  charges  of  $26.5  million  for  construction-in-
progress, consisting primarily of engineering work for potential upgrades to certain processing units at our Tulsa and El Dorado 
Refineries. During the quarter, we concluded not to pursue these projects in light of recent economic and market conditions.

Additionally,  in  the  fourth  quarter  of  2020,  our  budgeting  processes  identified  downward  forecast  revisions  specific  to  the 
Sonneborn  reporting  unit  within  our  Lubricants  and  Specialty  Products  segment  largely  from  declines  in  gross  margin  as 
compared to historic levels and an increase in forecasted capital expenditures. As such, we concluded it was more likely than 
not that the carrying value of the Sonneborn reporting unit exceeded its fair value, and we performed an interim quantitative test 
for goodwill impairment as of December 1, 2020. As a result of our impairment testing, we recognized a goodwill impairment 
charge of $81.9 million during the fourth quarter for the Sonneborn reporting unit. Our annual test performed on July 1, 2020 
indicated that the fair value of our El Dorado reporting unit exceeded its carrying value by approximately 10%. However, based 
on our reviews of updated budgets, and other factors such as economic and industry conditions we concluded that El Dorado 
and our other reporting units within our Lubricants and Specialty Products segment did not require an interim impairment test 
during the fourth quarter. 

We  continually  monitor  and  evaluate  various  factors  for  potential  indicators  of  goodwill  and  long-lived  asset  impairment.  A 
reasonable expectation exists that further deterioration in our operating results or overall economic conditions could result in an 
impairment of goodwill and / or additional long-lived asset impairments at some point in the future. Future impairment charges 
could be material to our results of operations and financial condition.

In performing our impairment tests of long-lived assets and goodwill, we developed cash flow forecasts for each of our asset 
groups and reporting units. Significant judgment is involved in performing these fair value estimates since the results are based 
on  forecasted  financial  information.  The  cash  flow  forecasts  include  significant  assumptions  such  as  planned  utilization,  end 
user demand, selling prices, gross margins, operating costs and capital expenditures. Another key assumption applied to these 
forecasts  to  determine  the  fair  value  of  an  asset  group  or  reporting  unit  is  the  discount  rate.  The  discount  rate  is  intended  to 
reflect the weighted average cost of capital for a market participant and the risks associated with the realization of the estimated 
future  cash  flows.  Assumptions  about  the  effects  of  the  COVID-19  pandemic  on  future  demand  and  market  conditions  are 
inherently subjective and difficult to forecast. Our fair value estimates are based on projected cash flows, which we believe to 
be reasonable. 

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, 2020, we have the following notional contract volumes related to all outstanding derivative contracts used 
to mitigate commodity price and foreign currency risk ( all maturing in 2021):

Interest Rate Risk Management
The market risk inherent in our fixed-rate debt is the potential change arising from increases or decreases in interest rates as 
discussed below.

For the fixed rate HollyFrontier Senior Notes and HEP Senior Notes, changes in interest rates will generally affect fair value of 
the  debt,  but  not  earnings  or  cash  flows.  The  outstanding  principal,  estimated  fair  value  and  estimated  change  in  fair  value 
(assuming a hypothetical 10% change in the yield-to-maturity rates) for this debt as of December 31, 2020 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, 2020, outstanding borrowings under the HEP Credit Agreement were $913.5 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  but  not  limited  to  fire,  explosion  and 
weather-related  perils.  We  maintain  various  insurance  coverages,  including  property  damage  and  business  interruption 
insurance,  subject  to  certain  deductibles  and  insurance  policy  terms  and  conditions.  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.

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.

Set forth below is our calculation of EBITDA.

Reconciliations of refinery operating information (non-GAAP performance measures) to amounts reported under generally 
accepted accounting principles in financial statements.

Refinery gross margin and net operating margin are non-GAAP performance measures that are used by our management and 
others to compare our refining performance to that of other companies in our industry. We believe these margin measures are 
helpful to investors in evaluating our refining performance on a relative and absolute basis. Refinery gross margin per 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 long-lived asset impairment charges, lower of cost or market inventory valuation 
adjustments or depreciation and amortization. Each of these component performance measures can be reconciled directly to our 
consolidated statements of income. Other companies in our industry may not calculate these performance measures in the same 
manner.

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, 2020 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, 2020, 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, 2020. That report is included herein.

63

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,  2020,  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, 2020, 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,  2020  and  2019,  the  related  consolidated 
statements of income, comprehensive income, cash flows, and equity for each of the three years in the period ended December 
31,  2020,  and  the  related  notes  of  the  Company  and  our  report  dated  February  24,  2021  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, 2020 and 2019, the related consolidated statements of income, comprehensive income, cash flows, and equity for each of 
the  three  years  in  the  period  ended  December  31,  2020,  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, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the 
period ended December 31, 2020, 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,  2020,  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 24, 2021 expressed an unqualified opinion thereon.

Adoption of ASU No. 2016-02 (Topic 842)

As discussed in Note 1 to the consolidated financial statements, the Company changed its method of accounting for leases in 
2019 to reflect the accounting method change due to the adoption of ASU 2016-02, Leases (Topic 842).

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.

Critical Audit Matters 

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial 
statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or 
disclosures  that  are  material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective  or  complex 
judgments.  The  communication  of  critical  audit  matters  does  not  alter  in  any  way  our  opinion  on  the  consolidated  financial 
statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on 
the critical audit matters or on the accounts or disclosures to which they relate.

Description of 
the Matter

How We 
Addressed the 
Matter in Our 
Audit

Valuation of Goodwill
At December 31, 2020, the Company’s goodwill was $2,294 million, including goodwill assigned to the 
Refining, Lubricants and Specialty Products, and HEP segments of $1,733 million, $248 million, and $313 
million, respectively. As described in Note 1 and Note 11 of the financial statements, goodwill is tested for 
impairment at least annually on July 1 at the reporting unit level or more frequently if events or changes in 
circumstances  indicate  the  asset  might  be  impaired.  During  the  fourth  quarter  of  2020,  the  Company 
performed interim goodwill impairment testing of the Sonneborn reporting unit included in the Lubricants 
and Specialty Products segment, resulting in an impairment charge of $82 million on this reporting unit.

Auditing management’s goodwill impairment tests was complex and highly judgmental for the Company’s 
Sonneborn and El Dorado Refinery reporting units due to the significant estimation required to determine 
the  fair  value  of  these  reporting  units.  In  particular,  the  fair  value  estimates  were  sensitive  to  significant 
assumptions,  such  as  revenue  growth  rates,  gross  margins,  and  discount  rates,  which  are  affected  by 
expectations about future market or economic conditions. These assumptions have a significant effect on 
the fair value estimates.

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over 
the Company's goodwill impairment testing process. For example, we tested controls over management's 
review of the significant inputs and assumptions used in determining the reporting unit fair values. 

To test the estimated fair value of the Company’s Sonneborn and El Dorado Refinery reporting units, we 
performed  audit  procedures  with  the  support  of  a  valuation  specialist  that  included,  among  others, 
assessing methodologies and testing the significant assumptions discussed above and the underlying data 
used  by  the  Company  in  its  analysis.  We  compared  the  significant  assumptions  used  by  management  to 
relevant  industry  and  economic  trends,  published  forward  prices,  third  party  analyst  reports,  historical 
operating results and other relevant factors. We performed sensitivity analyses of significant assumptions 
to  evaluate  the  changes  in  the  fair  value  of  the  reporting  units  that  would  result  from  changes  in  the 
assumptions.  We  also  tested  management’s  reconciliation  of  the  fair  value  of  the  reporting  units  to  the 
market capitalization of the Company.

Description of 
the Matter

Environmental Liabilities
At  December  31,  2020,  the  Company’s  accrual  for  environmental  liabilities  was  $115  million,  of  which 
$94  million  was  classified  as  other  long-term  liabilities.  As  described  in  Note  1  and  Note  12  of  the 
consolidated financial statements, these accruals include remediation and monitoring costs expected to be 
incurred over an extended period of time. Liabilities are recorded when site restoration and environmental 
remediation, cleanup and other obligations are either known or considered probable and can be reasonably 
estimated. 

How We 
Addressed the 
Matter in Our 
Audit

Auditing management’s estimates for environmental liabilities was challenging and highly judgmental due 
to  the  significant  judgment  required  to  develop  assumptions  related  to  future  costs  expected  for  the 
remediation  of  environmental  obligations.    In  particular,  the  liability  estimates  require  judgment  with 
respect to costs, time frame and extent of required remedial and clean-up activities.  

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over 
the Company’s accrued environmental liability cost estimate and review process.

To  test  management’s  accrued  environmental  liabilities,  we  performed  audit  procedures  that  included, 
among others, obtaining a rollforward of the environmental liabilities reflecting activity in the accruals for 
the  past  year,  performing  a  look  back  analysis  comparing  the  prior  year  short-term  accrual  estimates  to 
actual current year expenditures, and comparing actual expenditures made to supporting invoices and cash 
payments.  We also utilized an environmental specialist to assist in our evaluation of certain environmental 
site  accruals,  including  the  testing  of  a  sample  of  cost  estimates  by  inspecting  relevant  supporting 
documentation  and  performing  a  search  of  publicly  filed  records  with  environmental  agencies  to  test  the 
completeness of environmental liabilities.

Description of 
the Matter

How We 
Addressed the 
Matter in Our 
Audit

Impairment of Long-Lived Assets
As described in Note 11 of the financial statements, the Company recognized long-lived asset impairment 
charges of $204.7 million during the second quarter of 2020 related to property, plant, and equipment and 
other long-lived assets associated with the PCLI asset group. The Company evaluates long-lived assets for 
impairment by first identifying whether indicators of impairment exist. If indicators are present for an asset 
group, the Company evaluates recoverability by comparing the estimated future undiscounted cash flows to 
the carrying amount of the asset group. If the asset group's carrying amount exceeds its estimated future 
undiscounted cash flows, the fair value of the asset group is then estimated by management and compared 
to its carrying amount. An impairment charge is recognized on a long-lived asset group when the carrying 
amount exceeds fair value.

Auditing  management’s  evaluation  of  long-lived  asset  impairment  at  PCLI  involved  a  high  degree  of 
subjectivity and auditor judgment due to the estimation required to assess significant assumptions utilized 
in estimating the fair value of the asset group based on a discounted cash flow model, such as assumptions 
related to revenue growth rates, gross margins, and the discount rate. These assumptions have a significant 
effect on the fair value estimates. 

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over 
the  Company’s  long-lived  asset  impairment  evaluation  process,  including  controls  over  management’s 
review of significant assumptions used.

To test the Company’s long-lived asset impairment evaluation process, we performed audit procedures that 
included,  among  others,  assessing  the  methodologies  used,  evaluating  the  significant  assumptions 
discussed above and testing the completeness and accuracy of the underlying data used by the Company in 
its  analysis.  We  compared  the  significant  assumptions  used  by  management  to  relevant  industry  and 
economic  trends,  external  market  data,  historical  operating  results,  and  other  relevant  factors.  We  also 
performed  sensitivity  analyses  of  significant  assumptions  to  evaluate  the  changes  in  the  fair  value  of  the 
asset  group  that  would  result  from  changes  in  the  underlying  assumptions.  We  involved  our  valuation 
specialists to assist in our evaluation of certain significant assumptions used on the calculation of fair value 
estimates including the fair value of real and personal property and the discount rate.

NOTE 1:

Description of Business and Summary of Significant Accounting Policies

Description  of  Business:    References  herein  to  HollyFrontier  Corporation  (“HollyFrontier”)  include  HollyFrontier  and  its 
consolidated subsidiaries. In accordance with the Securities and Exchange Commission’s (“SEC”) “Plain English” guidelines, 
this  Annual  Report  on  Form  10-K  has  been  written  in  the  first  person.  In  these  financial  statements,  the  words  “we,”  “our,” 
“ours” and “us” refer only to HollyFrontier and its consolidated subsidiaries or to HollyFrontier or an individual subsidiary and 
not  to  any  other  person,  with  certain  exceptions.  Generally,  the  words  “we,”  “our,”  “ours”  and  “us”  include  Holly  Energy 
Partners,  L.P.  (“HEP”)  and  its  subsidiaries  as  consolidated  subsidiaries  of  HollyFrontier,  unless  when  used  in  disclosures  of 
transactions or obligations between HEP and HollyFrontier or its other subsidiaries. These financial statements contain certain 
disclosures of agreements that are specific to HEP and its consolidated subsidiaries and do not necessarily represent obligations 
of  HollyFrontier.  When  used  in  descriptions  of  agreements  and  transactions,  “HEP”  refers  to  HEP  and  its  consolidated 
subsidiaries.

We are an independent petroleum refiner and marketer that produces high-value light products such as gasoline, diesel fuel, jet 
fuel,  specialty  lubricant  products  and  specialty  and  modified  asphalt.  We  own  and  operate  petroleum  refineries  that  serve 
markets throughout the Mid-Continent, Southwest and Rocky Mountain geographic regions of the United States. In addition, 
we  produce  base  oils  and  other  specialized  lubricants  in  the  United  States,  Canada  and  the  Netherlands,  with  retail  and 
wholesale marketing of our products through a global sales network with locations in Canada, the United States, Europe, China 
and Latin America. 

As of December 31, 2020, we:

•

•

•

•

•

•

•

owned  and  operated  a  petroleum  refinery  in  El  Dorado,  Kansas  (the  “El  Dorado  Refinery”),  two  refinery  facilities 
located in Tulsa, Oklahoma (collectively, the “Tulsa Refineries”), a refinery in Artesia, New Mexico that is operated in 
conjunction with crude oil distillation and vacuum distillation and other facilities situated 65 miles away in Lovington, 
New  Mexico  (collectively,  the  “Navajo  Refinery”)  and  a  refinery  in  Woods  Cross,  Utah  (the  “Woods  Cross 
Refinery”);

owned  a  facility  in  Cheyenne,  Wyoming,  which  operated  as  a  petroleum  refinery  until  early  August  2020,  at  which 
time its assets began to be converted to renewable diesel production (the “Cheyenne Refinery”);

owned and operated Petro-Canada Lubricants Inc. (“PCLI”) located in Mississauga, Ontario, which produces base oils 
and other specialty lubricant products;

owned  and  operated  Sonneborn  (as  defined  below)  with  manufacturing  facilities  in  Petrolia,  Pennsylvania  and  the 
Netherlands, which produce specialty lubricant products, such as white oils, petrolatums and waxes;

owned and operated Red Giant Oil Company LLC (“Red Giant Oil”), which supplies locomotive engine oil and has 
storage and distribution facilities in Iowa and Wyoming, along with a blending and packaging facility in Texas;

owned and operated HollyFrontier Asphalt Company LLC (“HFC Asphalt”), which operates various asphalt terminals 
in Arizona, New Mexico and Oklahoma; and
owned  a  57%  limited  partner  interest  and  a  non-economic  general  partner  interest  in  HEP,  a  variable  interest  entity 
(“VIE”).  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 geographic regions of the United States.

In the third quarter of 2020, we permanently ceased petroleum refining operations at our Cheyenne Refinery and subsequently 
began converting certain assets at our Cheyenne Refinery to renewable diesel production. This decision was primarily based on 
a positive outlook in the market for renewable diesel and the expectation that future free cash flow generation at our Cheyenne 
Refinery would be challenged due to lower gross margins resulting from the economic impact of the COVID-19 pandemic and 
compressed crude differentials due to dislocations in the crude oil market. Additional factors included uncompetitive operating 
and maintenance costs forecasted for our Cheyenne Refinery and the anticipated loss of the Environmental Protection Agency’s 
(“EPA”) small refinery exemption.

During the second quarter of 2020, we recorded long-lived asset impairment charges of $232.2 million related to our Cheyenne 
Refinery  asset  group.  In  connection  with  the  cessation  of  petroleum  refining  operations  at  our  Cheyenne  Refinery,  we 
recognized $24.7 million in decommissioning expense for the year ended December 31, 2020. In addition, for the year ended 
December  31,  2020,  we  recorded  a  reserve  of  $9.0  million  against  our  repair  and  maintenance  supplies  inventory  and  $3.8 
million in employee severance costs related to the conversion of our Cheyenne Refinery to renewable diesel production. These 
decommissioning, inventory reserve and severance costs were recognized in operating expenses, of which $24.8 million was 
recorded in our Refining segment and $12.7 million was recorded in our Corporate and Other segment.

During the second quarter of 2020, we also initiated and completed a corporate restructuring. As a result of this restructuring, 
we recorded $3.7 million in employee severance costs, which were recognized primarily as operating expenses in our Refining 
segment and selling, general and administrative expenses in our Corporate and Other segment.

On November 12, 2018, we entered into an equity purchase agreement to acquire 100% of the issued and outstanding capital 
stock  of  Sonneborn  US  Holdings  Inc.  and  100%  of  the  membership  rights  in  Sonneborn  Coöperatief  U.A.  (collectively, 
“Sonneborn”). The acquisition closed on February 1, 2019.

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.

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. 

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.

In  2019,  HEP  Cushing  LLC,  a  wholly-owned  subsidiary  of  HEP,  and  Plains  Marketing,  L.P.,  a  wholly-owned  subsidiary  of 
Plains  All  American  Pipeline,  L.P.  (“Plains”),  formed  a  50/50  joint  venture,  Cushing  Connect  Pipeline  &  Terminal  LLC. 
Cushing Connect Pipeline & Terminal LLC and its two subsidiaries, Cushing Connect Pipeline and Cushing Connect Terminal, 
are each VIE’s because they do not have sufficient equity at risk to finance their activities without additional financial support. 
HEP is the primary beneficiary of two of these entities as HEP is constructing and will operate the Cushing Connect Pipeline, 
and HEP has more ability to direct the activities that most significantly impact the financial performance of Cushing Connect 
Pipeline  &  Terminal  LLC  and  Cushing  Connect  Pipeline.  Therefore,  HEP  consolidates  these  two  entities.  HEP  is  not  the 
primary beneficiary of Cushing Connect Terminal, which HEP accounts for using the equity method of accounting.

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.

75

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 expected credit losses from current economic conditions and management’s expectations of
future  economic  conditions.  Credit  losses  are  charged  to  the  allowance  for  doubtful  accounts  when  an  account  is  deemed 
uncollectible. Our allowance for doubtful accounts was $3.4 million at December 31, 2020 and $4.5 million at December 31, 
2019.

Accounts receivable attributable to crude oil resales generally represent the sale 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 and Sonneborn businesses are stated at the lower of cost, using the first-in, first-out 
(“FIFO”) method, or net realizable value.

Inventories consisting of process chemicals, materials and maintenance supplies and renewable identification numbers (“RINs”) 
are stated at the lower of weighted-average cost or net realizable value.

Leases:  Effective  January  1,  2019,  we  adopted  Accounting  Standards  Update  (“ASU”)  2016-02,  “Leases”  (Topic  842).  At 
inception,  we  determine  if  an  arrangement  is  or  contains  a  lease.  Right-of-use  (“ROU”)  assets  represent  our  right  to  use  an 
underlying asset for the lease term and lease liabilities represent our payment obligation under the leasing arrangement. ROU 
assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease 
term. We use our estimated incremental borrowing rate (“IBR”) to determine the present value of lease payments as most of our 
leases do not contain an implicit rate. Our IBR represents the interest rate which we would pay to borrow, on a collateralized 
basis, an amount equal to the lease payments over a similar term in a similar economic environment. We use the implicit rate 
when readily determinable. 

Operating leases are recorded in operating lease right-of-use assets and current and noncurrent operating lease liabilities on our 
consolidated  balance  sheet.  Finance  leases  are  included  in  properties,  plants  and  equipment  and  accrued  liabilities  and  other 
long-term liabilities on our consolidated balance sheet.

Our lease term includes an option to extend the lease when it is reasonably certain that we will exercise that option. Leases with 
a term of 12 months or less are not recorded on our balance sheet. For certain equipment leases, we apply a portfolio approach 
for the operating lease ROU assets and liabilities. Also, as a lessee, we separate non-lease components that are identifiable and 
exclude them from the determination of net present value of lease payment obligations. In addition, HEP, as a lessor, does not 
separate the non-lease (service) component in contracts in which the lease component is the dominant component. HEP treats 
these combined components as an operating lease.

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 14 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 $42.6 million and $35.9 million at December 31, 2020 and 2019, respectively, which are 
included in “Other long-term liabilities” in our consolidated balance sheets. Accretion expense was insignificant for the years 
ended December 31, 2020, 2019 and 2018. 

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. Our goodwill impairment 
testing first entails either a quantitative assessment or an optional qualitative assessment to determine whether it is more likely 
than  not  that  the  fair  value  of  a  reporting  unit  is  less  than  its  carrying  amount.  If  we  determine  that  based  on  the  qualitative 
factors that it is more likely than not that the carrying amount of the reporting unit is greater than its fair value, a quantitative 
test is performed in which we estimate the fair value of the related reporting unit. If the carrying amount of a reporting unit 
exceeds its fair value, the goodwill of that reporting unit is impaired, and we measure goodwill impairment as the excess of the 
carrying amount of the reporting unit over the related fair value. 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.

For purposes of long-lived asset impairment evaluation, we have grouped our long-lived assets as follows: (i) our refinery asset 
groups, which include certain HEP logistics assets, (ii) our Lubricants and Specialty Products asset groups and (iii) our HEP 
asset groups, which comprises HEP assets not included in our refinery asset groups. These asset groups represent the lowest 
level  for  which  independent  cash  flows  can  be  identified.  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  11  for  additional  information  regarding  our  goodwill  and  long-lived  assets  including  impairment  charges  recorded 
during the years ended December 31, 2020 and 2019. 

Equity  Method  Investments:    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”). HEP also accounts for Cushing Connect Terminal, a subsidiary of the Cushing 
Connect Pipeline & Terminal LLC joint venture, using the equity method of accounting, as HEP does not have the ability to 
direct the activities that most significantly impact the entity. As of December 31, 2020, HEP's underlying equity and recorded 
investment balances in the joint ventures are $93.2 million and $120.5 million respectively. The differences are being amortized 
as adjustments to HEP's pro-rata share of earnings in the joint ventures.

Revenue Recognition:  Revenues 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. 

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. Our lubricants and specialty products business also 
has agreements that create an obligation to deliver products at a future date for which consideration has already been received 
and recorded as deferred revenue. This revenue is recognized when the products are delivered to the customer.

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 $158.4 million, $141.9 million and $110.9 million for the 
years ended December 31, 2020, 2019 and 2018, 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. We accrue for contingencies when it is probable that a loss has occurred and when the amount of that 
loss is reasonably estimable. 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:  Assets  and  liabilities  recorded  in  foreign  currencies  are  translated  into  U.S.  dollars  using 
exchange rates in effect as of the balance sheet date. Revenue and expense accounts are translated using the weighted-average 
exchange  rates  during  the  period  presented.  Foreign  currency  translation  adjustments  are  recorded  as  a  component  of 
accumulated other comprehensive income.

In  connection  with  our  PCLI  acquisition,  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 inventory repurchase obligations that are subsequently reversed when the inventories are repurchased. For the 
years ended December 31, 2020, 2019 and 2018, we received proceeds of $44.9 million, $52.1 million and $51.2 million and 
subsequently repaid $46.4 million, $49.2 million and $52.5 million, respectively, under these sell / buy transactions.

Accounting Pronouncements - Recently Adopted

Income Tax Accounting
In  December  2019,  ASU  2019-12,  “Simplifying  the  Accounting  for  Income  Taxes,”  was  issued  which  eliminates  some 
exceptions to the general approach in ASC Topic 740 “Income Taxes” and also provides clarification of other aspects of ASC 
740.  We  adopted  this  standard  effective  January  1,  2020  on  a  prospective  basis,  and  it  did  not  have  a  material  affect  on  our 
financial condition, results of operations or cash flows for the periods presented.

Fair Value Measurements
In  August  2018,  ASU  2018-13,  “Changes  to  the  Disclosure  Requirements  for  Fair  Value  Measurement,”  was  issued  which 
removed, modified and added certain disclosures for fair value measurements. We adopted this standard effective January 1, 
2020, and it did not affect our financial condition, results of operations or cash flows.

Defined Benefit Plans
In  August  2018,  ASU  2018-14,  “Changes  to  the  Disclosure  Requirements  for  Defined  Benefit  Plans,”  was  issued  which 
removed disclosure requirements for (i) the amounts in accumulated other comprehensive income expected to be recognized as 
components  of  net  periodic  benefit  cost  over  the  next  fiscal  year  and  (ii)  the  effects  of  a  one-percentage-point  change  in 
assumed health care cost trend rates on the aggregate of the service and interest cost components of net periodic benefit costs 
and the benefit obligation for postretirement health care benefits. Additionally, a new disclosure required under this standard is 
an  explanation  of  the  reasons  for  significant  gains  and  losses  related  to  changes  in  the  benefit  obligation  for  the  period.  We 
adopted this standard effective December 31, 2020 with the updated disclosures in Note 18. The adoption of this standard had 
no impact on our financial condition, results of operations or cash flows.

Credit Losses Measurement
In June 2016, ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” was issued requiring measurement of 
all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based 
on  historical  experience,  current  conditions  and  reasonable  and  supportable  forecasts.  We  adopted  this  standard  effective 
January 1, 2020, at which time our review of historic and expected credit losses resulted in a decrease of $3.2 million in our 
reserve  for  doubtful  accounts.  Based  upon  our  assessment  of  the  potential  impact  of  current  and  forecasted  conditions,  we 
increased our reserve for doubtful accounts by $2.1 million during the the year ended December 31, 2020. Assumptions about 
the potential effects of the COVID-19 pandemic on our estimate of expected credit losses are inherently subjective and difficult 
to  forecast.  However,  we  believe  that  our  current  estimate  of  allowance  for  doubtful  accounts  to  be  reasonable  based  upon 
current information and forecasts.

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. Aggregate consideration totaled $701.6 million and consisted of $662.7 million in cash 
paid  at  acquisition,  net  of  cash  acquired.  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 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 Sonneborn assets and liabilities as of the February 1, 2019 acquisition date, with 
the excess purchase price recorded as goodwill. This goodwill was assigned to our Lubricants and Specialty Products segment 
and is not deductible for income tax purposes.

Fair  values  were  as  follows:  cash  and  cash  equivalents  $38.9  million,  current  assets  $139.4  million,  properties,  plants  and 
equipment $168.2 million, goodwill $282.3 million, intangibles and other noncurrent assets $231.5 million, current liabilities 
$47.9 million and deferred income tax and other long-term liabilities $110.8 million. 

Intangibles included customer relationships, trademarks, patents and technical know-how totaling $214.6 million that are being 
amortized on a straight-line basis over a 12-year period. 

Our consolidated financial and operating results reflect the Sonneborn operations beginning February 1, 2019. Our results of 
operations  include  revenue  and  income  before  income  taxes  of  $340.3  million  and  $5.1  million,  respectively,  for  the  period 
from February 1, 2019 through December 31, 2019 related to these operations.

The  following  unaudited  pro  forma  information  for  the  years  ended  December  31,  2019  and  2018  presents  the  revenues  and 
operating income for our Lubricants and Specialty Products segment assuming the acquisition of Sonneborn had occurred as of 
January 1, 2018. The proforma effects on consolidated HFC revenue and operating income are not material.

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 were 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. 

We incurred $2.0 million, $24.2 million and $3.6 million, for the years ended December 31, 2020, 2019 and 2018, respectively, 
in incremental direct integration and regulatory costs that principally relate to legal, advisory, regulatory and other professional 
fees and are presented as selling, general and administrative expenses.

NOTE 3:

Leases

Lessee

We have operating and finance leases for land, buildings, pipelines, storage tanks, transportation and other equipment for our 
operations. Our leases have remaining terms of one to 59 years, some of which include options to extend the leases for up to 10 
years.  Certain  of  our  leases  for  pipeline  assets  include  provisions  for  variable  payments  which  are  based  on  a  measure  of 
throughput and also contain a provision for the lessor to adjust the rate per barrel periodically over the life of the lease. These 
variable costs are not included in the initial measurement of ROU assets and lease liabilities.

for petroleum tank storage, with estimated future lease payments of $2.6 million, expected to commence in the first quarter of 
2021.

Lessor

Our consolidated statements of income reflect lease revenue recognized by HEP for contracts with third parties in which HEP is 
the lessor. 

Substantially all of the assets supporting contracts meeting the definition of a lease have long useful lives, and HEP believes 
these  assets  will  continue  to  have  value  when  the  current  agreements  expire  due  to  HEP's  risk  management  strategy  for 
protecting the residual fair value of the underlying assets by performing ongoing maintenance during the lease term.

One  of  HEP’s  throughput  agreements  with  Delek  US  Holdings,  Inc.  (“Delek”)  was  partially  renewed  during  the  year  ended 
December 31, 2020. Certain components of this agreement met the criteria of sales-type leases since the underlying assets are 
not  expected  to  have  an  alternative  use  at  the  end  of  the  lease  term  to  anyone  other  than  Delek.  Under  sales-type  lease 
accounting, at the commencement date, the lessor recognizes a net investment in the lease, based on the estimated fair value of 
the underlying leased assets at contract inception, and derecognizes the underlying assets with the difference recorded as selling 
profit or loss arising from the lease. Therefore, HEP recognized a gain on sales-type leases totaling $33.8 million during the 
year ended December 31, 2020. This sales-type lease transaction, including the related gain, was a non-cash transaction.

accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. HEP

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,  as  well  as  other  third-party  refineries,  in  the  Mid-Continent,  Southwest  and  Rocky  Mountain 
geographic regions of the United States. Additionally, as of December 31, 2020, HEP owned 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”);  Cheyenne  Pipeline,  LLC,  the  owner  of  a 
pipeline  running  from  Fort  Laramie,  Wyoming  to  Cheyenne,  Wyoming  (the  “Cheyenne  Pipeline”)  and  Cushing  Connect 
Pipeline & Terminal LLC (“Cushing Connect”), the owner of a crude oil storage terminal in Cushing, Oklahoma and a pipeline 
under construction that will run from Cushing, Oklahoma to our Tulsa Refineries.

At December 31, 2020, 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 by 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 80% of HEP’s total revenues for the year ended December 31, 2020. 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 13 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.

Cushing Connect Joint Venture
In  October  2019,  HEP  Cushing  LLC  (“HEP  Cushing”),  a  wholly-owned  subsidiary  of  HEP,  and  Plains  Marketing,  L.P. 
(“PMLP”), a wholly-owned subsidiary of Plains All American Pipeline, L.P. (“Plains”), formed a 50/50 joint venture, Cushing 
Connect, for (i) the development, construction, ownership and operation of a new 160,000 barrel per day common carrier crude 
oil pipeline (the “Cushing Connect Pipeline”) that will connect the Cushing, Oklahoma crude oil hub to our Tulsa Refineries 
and (ii) the ownership and operation of 1.5 million barrels of crude oil storage in Cushing, Oklahoma (the “Cushing Connect 
Terminal”). The Cushing Connect Terminal was fully in service beginning in April 2020, and the Cushing Connect Pipeline is 
expected to be placed in service during the second quarter of 2021. Long-term commercial agreements have been entered into 
to support the Cushing Connect assets. 

Cushing  Connect  will  contract  with  an  affiliate  of  HEP  to  manage  the  construction  and  operation  of  the  Cushing  Connect 
Pipeline  and  with  an  affiliate  of  Plains  to  manage  the  operation  of  the  Cushing  Connect  Terminal.  The  total  investment  in 
Cushing  Connect  will  be  shared  proportionately  among  the  partners,  and  HEP  estimates  its  share  of  the  cost  of  the  Cushing 
Connect  Terminal  contributed  by  Plains  and  Cushing  Connect  Pipeline  construction  costs  are  approximately  $65.0  million.  
However, any Cushing Connect Pipeline construction costs exceeding 10% of the budget are borne solely by HEP.

Transportation Agreements
HEP serves our refineries under long-term pipeline, terminal and tankage throughput agreements and refinery processing tolling 
agreements  expiring  from  2021  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, 
2020, these agreements required minimum annualized payments to HEP of $351.1 million. However, subsequent to year end, 
these agreements were modified to account for the conversion of our Cheyenne Refinery to renewable diesel production, and as 
of January 1, 2021, require minimum annualized payments to HEP of $341.9 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,  2020,  HEP  did  not  issue  any  common  units  under  this  program.  As  of  December  31,  2020,  HEP    has  issued 
2,413,153 common units under this program, providing $82.3 million in gross proceeds.

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 5:

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

As  of  December  31,  2020,  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 2025. 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  Codification  606-10-50-14A.  Aggregate  minimum  volumes  expected  to  be  sold  (future  performance

NOTE 6:

Fair Value Measurements

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

Fair  value  measurements  are  derived  using  inputs  (assumptions  that  market  participants  would  use  in  pricing  an  asset  or 
liability, including assumptions about risk). GAAP categorizes inputs used in fair value measurements into three broad levels as 
follows:

•

•

•

(Level 1) Quoted prices in active markets for identical assets or liabilities.

(Level 2) Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and 
liabilities  in  active  markets,  similar  assets  and  liabilities  in  markets  that  are  not  active  or  can  be  corroborated  by 
observable market data.

(Level 3) Unobservable inputs that are supported by little or no market activity and that are significant to the fair value 
of the assets or liabilities. This includes valuation techniques that involve significant unobservable inputs.

The carrying amounts of derivative instruments at December 31, 2020 and 2019 were as follows:

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. The fair value of the forward sales and purchase contracts are 
computed  using  quoted  forward  commodity  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. 

Nonrecurring Fair Value Measurements
During  the  year  ended  December  31,  2020,  we  recognized  goodwill  and  long-lived  asset  impairment  charges  based  on  fair 
value  measurements  utilized  during  our  goodwill  and  long-lived  asset  impairment  testing  (see  Note  11).  The  fair  value 
measurements  were  based  on  a  combination  of  valuation  methods  including  discounted  cash  flows,  the  guideline  public 
company and guideline transaction methods and obsolescence adjusted replacement costs, all of which are Level 3 inputs.

During the year ended December 31, 2020, HEP recognized a gain on sales-type leases (see Note 4). The estimated fair value of 
the underlying leased assets at contract inception and the present value of the estimated unguaranteed residual asset at the end 
of the lease term were used in determining the net investment in leases and related recognized gain on sales-type leases. The 
asset valuation estimates included Level 3 inputs based on a replacement cost valuation method.

Earnings Per Share

Basic earnings per share is calculated as net income (loss) attributable to HollyFrontier stockholders, adjusted for participating 
securities’ share in earnings divided by the average number of shares of common stock outstanding. Diluted earnings per share 
includes the incremental shares resulting from our restricted stock units and performance share units if the effect is dilutive. The 
following  is  a  reconciliation  of  the  denominators  of  the  basic  and  diluted  per  share  computations  for  net  income  (loss)

Stock-Based Compensation

We  have  a  principal  share-based  compensation  plan  (the  “2020  Long-Term  Incentive  Plan”),  which  allows  us  to  grant  new 
equity awards until February 12, 2030. We also have a long-term incentive compensation plan which expired pursuant to its 
terms on December 31, 2020, but it will continue to govern outstanding equity awards granted thereunder. The compensation 
cost  charged  against  income  for  these  plans  was  $29.7  million,  $41.5  million  and  $39.0  million  for  the  years  ended 
December  31,  2020,  2019  and  2018,  respectively.  Our  accounting  policy  for  the  recognition  of  compensation  expense  for 
awards with pro-rata vesting is to expense the costs ratably over the vesting periods.

Additionally, HEP maintains a share-based compensation plan for Holly Logistic Services, L.L.C.'s non-employee directors and 
certain executives and employees. Compensation cost attributable to HEP’s share-based compensation plan was $2.2 million, 
$2.5 million and $3.2 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Restricted Stock Units
Under our long-term incentive plan, we grant certain officers and other key employees restricted stock unit awards, which are 
payable in stock or cash and generally vest over a period of three years. Restricted stock unit award recipients have the right to 
receive dividends, however, restricted stock units do not have any other rights of absolute ownership. Upon vesting, restrictions 
on the 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 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.

fair value of $28.2 million, $30.9 million and $30.0 million, respectively. For the years ended December 31, 2019 and 2018, we 
granted  restricted  stock  units  having  a  weighted  average  grant  date  fair  value  of  $52.62  and  $64.96,  respectively.  As  of 
December 31, 2020, there was $40.4 million of total unrecognized compensation cost related to non-vested restricted stock unit 
grants. That cost is expected to be recognized over a weighted-average period of 1.7 years. For the years ended December 31, 
2020, 2019 and 2018, we paid $1.3 million, $1.7 million and $0.1 million, respectively, in cash equal to the value of the stock 
award on the vest date to certain employees to settle 55,222, 32,648 and 2,481, respectively, restricted stock units. 

Performance Share Units
Under  our  long-term  incentive  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. Holders of performance share units have the right to receive dividend equivalents and 
other distributions with respect to such performance share units based on the target level of payout.

A summary of performance share unit activity and changes during the year ended December 31, 2020 is presented below:

performance share units having a grant date fair value of $6.2 million. For the years ended December 31, 2019 and 2018, we 
issued common stock upon the vesting of the performance share units having a grant date fair value of $7.3 million and $8.8 
million,  respectively.  As  of  December  31,  2020,  there  was  $14.5  million  of  total  unrecognized  compensation  cost  related  to 
non-vested performance share units having a grant date fair value of $35.45 per unit. That cost is expected to be recognized 
over a weighted-average period of 2.5 years.

Our  inventories  that  are  valued  at  the  lower  of  LIFO  cost  or  market  reflect  a  valuation  reserve  of  $318.9  million  and 
$240.4 million at December 31, 2020 and 2019, respectively. The December 31, 2019 market reserve of $240.4 million was 
reversed due to the sale of inventory quantities that gave rise to the 2019 reserve. A new market reserve of $318.9 million was 
established as of December 31, 2020 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 totaling $78.5 million for the year ended December 31, 2020, a 
decrease  of  $119.8  million  for  the  year  ended  December  31,  2019  and  an  increase  of  $136.3  million  for  the  year  ended 
December 31, 2018.

At December 31, 2020, 2019 and 2018, 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, 2020, we recognized a charge of $36.9 million to cost of products sold as we 
liquidated certain quantities of LIFO inventory at our Cheyenne Refinery that were carried at historical acquisition costs above 
market prices at the time of liquidation

During the three months ended September 30, 2019, the EPA granted the Cheyenne Refinery and the Woods Cross Refinery 
each  a  one-year  small  refinery  exemption  from  the  Renewable  Fuel  Standard  (“RFS”)  program  requirements  for  the  2018 
calendar year end. As a result, the Cheyenne Refinery’s and the Woods Cross Refinery’s gasoline and diesel production are not 
subject  to  the  Renewable  Volume  Obligation  (“RVO”)  for  2018.  In  the  third  quarter  of  2019,  we  increased  our  inventory  of 
RINs and reduced our cost of products sold by $36.6 million representing the  net cost of the RINs charge to cost of products 
sold  in  2018,  less  the  loss  incurred  for  selling  2018  vintage  RINs  in  excess  of  those  which  we  can  use  subject  to  the  20% 
carryover limit.

During the three months ended June 30, 2018, the EPA granted the Woods Cross Refinery a one-year small refinery exemption 
from  the  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 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.

NOTE 11: Goodwill, Long-lived Assets and Intangibles

Goodwill and long-lived assets
As  of  December  31,  2020,  our  goodwill  balance  was  $2.3  billion.  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.

Goodwill and long-lived asset impairment testing
During the second quarter of 2020, we determined that indicators of potential goodwill and long-lived asset impairments were 
present and performed recoverability testing for long-lived assets and an interim test for goodwill impairment as of May 31, 
2020.  Impairment  indicators  included  the  recent  economic  slowdown  caused  by  the  COVID-19  pandemic,  reductions  in  the 
prices of our finished goods and raw materials and the related decrease in our gross margins, as well as the recent decline in our 
market capitalization. Additionally, our second quarter announcement of the planned conversion of our Cheyenne Refinery to 
renewable  diesel  production  was  also  considered  a  triggering  event  requiring  assessment  of  potential  impairments  to  the 
carrying value of our Cheyenne Refinery asset group. As a result of our long-lived asset recoverability testing, we determined 
that the carrying value of the long-lived assets of our Cheyenne Refinery and PCLI asset groups were not recoverable, and thus 
recorded long-lived asset impairment charges of $232.2 million and $204.7 million, respectively, in the second quarter of 2020. 
Our interim goodwill impairment testing indicated that there was no impairment of goodwill at our Refining and Lubricants and 
Specialty  Products  reporting  units  as  of  May  31,  2020.  The  estimated  fair  values  of  the  Cheyenne  Refinery  and  PCLI  asset 
groups  were  determined  using  a  combination  of  the  income  and  cost  approaches.  The  income  approach  was  based  on 
management’s  best  estimates  of  the  expected  future  cash  flows  over  the  remaining  useful  life  of  the  asset  group.  The  cost 
approach  utilized  assumptions  for  the  current  replacement  costs  of  similar  assets  adjusted  for  estimated  depreciation  and 
economic obsolescence. These fair value measurements involve significant unobservable inputs (Level 3 inputs). See Note 6 for 
further discussion of Level 3 inputs.

As  of  July  1,  2020,  we  performed  our  annual  goodwill  impairment  testing  quantitatively  and  determined  there  was  no 
impairment of goodwill attributable to our reporting units at that time.  

During  the  fourth  quarter  of  2020,  we  incurred  long-lived  asset  impairment  charges  of  $26.5  million  for  construction-in-
progress, consisting primarily of engineering work for potential upgrades to certain processing units at our Tulsa and El Dorado 
Refineries. During the quarter, we concluded not to pursue these projects in light of recent economic and market conditions.

Additionally, in the fourth quarter of 2020, our annual budgeting process identified downward forecast revisions specific to the 
Sonneborn  reporting  unit  within  our  Lubricants  and  Specialty  Products  segment;  largely  from  declines  in  gross  margin  as 
compared to historic levels and an increase in forecasted capital expenditures. As such, we concluded it was more likely than 
not that the carrying value of the Sonneborn reporting unit exceeded its fair value, and we performed an interim quantitative test 
for goodwill impairment as of December 1, 2020. As a result of our impairment testing, we recognized a goodwill impairment 
charge of $81.9 million during the fourth quarter for the Sonneborn reporting unit. No other reporting units required an interim 
impairment test during the fourth quarter.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The estimated fair values of our reporting units tested quantitatively in the current year were derived using a combination of 
income  and  market  approaches.  The  income  approach  reflects  expected  future  cash  flows  based  on  estimated  forecasted 
production levels, selling prices, gross margins, 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). See Note 6 for further discussion of Level 3 inputs.

There was no impairment of long-lived assets during the years ended December 31, 2019 and 2018.

During the year ended December 31, 2019, we recorded a goodwill impairment charge of $152.7 million to fully impair the 
goodwill of the PCLI reporting unit included in our Lubricants and Specialty Products segment. There was no impairment of 
goodwill during the year ended December 31, 2018.

A reasonable expectation exists that further deterioration in our operating results or overall economic conditions could result in 
an  impairment  of  goodwill  and  /  or  additional  long-lived  assets  impairments  at  some  point  in  the  future.  Future  impairment 
charges could be material to our results of operations and financial condition.

Amortization expense was $34.1 million, $33.8 million and $16.6 million for the years ended December 31, 2020, 2019 and 
2018, respectively and expected to approximate $34.1 million for each of the next five years.

NOTE 12: Environmental

We  expensed  $7.1  million,  $11.2  million  and  $14.8  million  for  the  years  ended  December  31,  2020,  2019  and  2018, 
respectively,  for  environmental  remediation  obligations.  The  accrued  environmental  liability  reflected  in  our  consolidated 
balance sheets was $115.0 million and $117.7 million at December 31, 2020 and 2019, respectively, of which $94.0 million and 
$95.6  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 13: 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, 2020, we were in compliance with all covenants, had 
no outstanding borrowings and had outstanding letters of credit totaling $5.7 million under the HollyFrontier Credit Agreement.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Continued

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, 2020, HEP received advances totaling $258.5 million and repaid $310.5 million under the 
HEP Credit Agreement. At December 31, 2020, HEP was in compliance with all of its covenants, had outstanding borrowings 
of $913.5 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 was 2.58%and 4.24% for December 31, 2020 and 2019, 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
On  September  28,  2020,  we  completed  a  public  offering  of  $350.0  million  in  aggregate  principal  amount  of  2.625%  senior 
notes maturing October 2023 (the “2.625% Senior Notes”) and $400.0 million in aggregate principal amount of 4.500% senior 
notes maturing October 2030 (the “4.500% Senior Notes”). We intend to use the net proceeds for general corporate purposes, 
which may include capital expenditures.

As  a  result,  as  of  December  31,  2020,  our  outstanding  senior  notes  consist  of  $1.0  billion  in  aggregate  principal  amount  of 
5.875% senior notes maturing April 2026 (the “5.875% Senior Notes”), the 2.625% Senior Notes and the 4.500% Senior Notes 
(collectively, the “HollyFrontier Senior Notes”). 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 term of each lease, and the lease payments are recorded as interest expense. The leases mature on February 1, 2022. Upon 
maturity,  we  must  either  satisfy  the  obligation  at  fair  market  value  or  refinance  to  extend  the  maturity.  These  financing 
arrangements  are  recorded  at  a  Level  2  fair  value  totaling  $43.9  million  and  $40.0  million  at  December  31,  2020  and  2019, 
respectively, and are included in “Accrued liabilities” in our consolidated balance sheets. See Note 6 for additional information 
on Level 2 inputs.

HEP Senior Notes
On  February  4,  2020,  HEP  closed  a  private  placement  of  $500.0  million  in  aggregate  principal  amount  of  5.0%  HEP  senior 
unsecured notes maturing in February 2028 (the “HEP Senior Notes”). On February 5, 2020, HEP redeemed its existing $500.0 
million aggregate principal amount of 6.0% senior notes maturing August 2024 at a redemption cost of $522.5 million. HEP 
recognized a $25.9 million early extinguishment loss consisting of a $22.5 million debt redemption premium and unamortized 
discount and financing costs of $3.4 million. HEP funded the $522.5 million redemption with proceeds from the issuance of its 
5.0% senior notes and borrowing under the HEP Credit Agreement.

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.  HEP  was  in  compliance  with  the  restrictive  covenants  for  the  HEP  Senior  Notes  as  of 
December  31,  2020.  At  any  time  when  the  HEP  Senior  Notes  are  rated  investment  grade  by  either  Moody’s  or  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.

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 14: 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.

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.  We  also 
periodically  have  swap  contracts  to  lock  in  basis  spread  differentials  on  forecasted  purchases  of  crude  oil  and  forward  sales 
contracts  that  lock  in  the  prices  of  future  sales  of  crude  oil  and  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.

The  following  table  presents  the  pre-tax  effect  on  other  comprehensive  income  (“OCI”)  and  earnings  due  to  fair  value 
adjustments and maturities of hedging instruments under hedge accounting:

Economic Hedges
We  have  commodity  contracts  including  NYMEX  futures  contracts  to  lock  in  prices  on  forecasted  purchases  and  sales  of 
inventory and forward purchase and sell contracts, as well as periodically have contracts to lock in basis spread differentials on 
forecasted purchases of crude oil and swap contracts to lock in the crack spread of WTI and 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. In addition, our catalyst financing arrangements discussed in Note 13 could require 
repayment under certain conditions based on the future pricing of platinum, which is an embedded derivative. These contracts 
are measured at fair value with offsetting adjustments (gains / losses) recorded directly to income.

At  December  31,  2020,  we  had  a  pre-tax  net  unrealized  loss  of  $0.4  million  classified  in  accumulated  other  comprehensive 
income  that  relates  to  all  accounting  hedges  having  contractual  maturities  through  2021,  which  assuming  commodity  prices 
remain unchanged 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.

At  December  31,  2020,  2019  and  2018,  there  were  $54.9  million,  $56.6  million,  and  $53.8  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. 

Approximately  $53.7  million  of  the  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 possible court rulings in favor of the IRS).

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 2015. Other than the federal claim noted above, we have materially concluded all U.S. 
federal income tax matters for tax years through December 31, 2016.

In November 2019, our Board of Directors approved a $1.0 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, 2020, we 
had  not  repurchased  common  stock  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, 2020, 2019 and 2018, we withheld shares of our common stock from certain employees 
in the amounts of $7.6 million, $21.9 million and $19.6 million, respectively. These withholdings were made under the terms of 
restricted stock unit 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.

Certain  PCLI  employees  are  participants  in  union  and  non-union  pension  plans  which  are  closed  to  new  entrants.  It  is  our 
intention  that,  effective  June  30,  2022,  no  additional  benefits  will  be  accrued  under  these  plans,  and  the  plans  will  become 
frozen and employees will be transitioned to a defined contribution plan. Accordingly, these changes have been accounted for 
as  curtailments  and  contractual  termination  benefits.  In  addition,  Sonneborn  employees  in  the  Netherlands  have  a  defined 
benefit pension plan which was frozen and all plan participants became inactive in 2016. The plan assets are in the form of a 
third-party insurance contract that is valued based on the assets held by the insurer and insures a value which approximates the 
accrued benefits related to the plan’s accumulated benefit obligation. At that time, a new plan was established to provide future 
indexation benefits to participants who had accrued benefits under the expiring arrangements.

mix of 16% Canadian equities, 75% fixed income, 5% real estate and infrastructure and 4% other.

We  expect  to  contribute  $3.5  million  to  the  PCLI  and  Sonneborn  pensions  plans  in  2021.  Benefit  payments,  which  reflect 
expected future service, are expected to be paid as follows: $2.1 million in 2021, $2.5 million in 2022, $3.0 million in 2023, 
$3.3 million in 2024, $3.8 million in 2025 and $24.5 million in 2026 to 2030.

Post-retirement Healthcare Plans
We have post-retirement healthcare and other benefits plans that are available to certain of our employees who satisfy certain

The components, other than service cost, of our net periodic post-retirement credit are recorded in Other, net in our consolidated 
statements  of  income.  Prior  service  credits  are  amortized  over  the  average  remaining  effective  period  to  obtain  full  benefit 
eligibility for participants.

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  for  each  of  the  years  ended  December  31,  2020,  2019  and  2018  in 
connection with this plan. The accrued liability reflected in the consolidated balance sheets was $2.5 million and $2.4 million at 
December 31, 2020 and 2019, respectively. As of December 31, 2020, the projected benefit obligation under this plan was $2.5 
million. Annual benefit payments of $0.2 million are expected to be paid through 2030, which reflect expected future service.

Defined Contribution Plans
We have defined contribution plans that cover substantially all qualified employees in the U.S, Canada and the Netherlands. 
Our  contributions  are  based  on  an  employee's  eligible  compensation  and  years  of  service.  We  also  partially  match  our 
employees’ contributions. We expensed $43.3 million, $30.3 million and $19.1 million for the years ended December 31, 2020, 
2019 and 2018, respectively, in connection with these plans.

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 filed a business interruption claim with our insurance carriers related to a loss at our Woods Cross Refinery that occurred in 
the  first  quarter  2018.  During  the  year  ended  December  31,  2020,  we  reached  a  final  settlement  agreement  regarding  the 
amounts  owed  to  us  pursuant  to  our  business  interruption  coverage,  and  we  recognized  a  gain  of  $81.0  million,  which  is 
reflected in our Corporate and Other segment.

During  2017,  2018  and  2019,  the  EPA  granted  the  Cheyenne  Refinery  and  Woods  Cross  Refinery  each  a  one-year  small 
refinery exemption from the RFS program requirements for the 2016, 2017 and 2018, respectively, calendar years. As a result, 
the  Cheyenne  Refinery’s  and  Woods  Cross  Refinery’s  gasoline  and  diesel  production  are  not  subject  to  the  RVO  for  the 
respective years. Upon each exemption granted, we increased our inventory of RINs and reduced our cost of products sold.

Various  subsidiaries  of  HollyFrontier  are  currently  intervenors  in  three  lawsuits  brought  by  renewable  fuel  interest  groups 
against the EPA in federal courts alleging violations of the RFS under the Clean Air Act and challenging the EPA’s handling of 
small refinery exemptions. We intervened to vigorously defend the EPA’s position on small refinery exemptions because we 
believe the EPA correctly applied applicable law to the matters at issue. On January 24, 2020, in the first of these lawsuits, the 
U.S. Court of Appeals for the Tenth Circuit vacated the small refinery exemptions granted to two of our refineries for 2016 and 
remanded the case to the EPA for further proceedings. On April 15, 2020, the Tenth Circuit entered its mandate, remanding the 
matter back to the EPA. On September 4, 2020, various subsidiaries of HollyFrontier filed a Petition for a Writ of Certiorari 
with  the  U.S.  Supreme  Court  appealing  the  Tenth  Circuit  decision.  On  January  8,  2021,  the  U.S.  Supreme  Court  granted 
HollyFrontier's petition. We anticipate a decision from the Supreme Court in June 2021. We expect that we will not know what 
steps the EPA will take with respect to our 2016 small refinery exemptions, or how the case will impact future small refinery 
exemptions until after the Supreme Court's decision in this matter. The second lawsuit is before the Tenth Circuit. The matter is 
fully briefed and remains pending before that court. The third lawsuit is before the DC Circuit. Briefing of the issues before the 
court commenced on December 7, 2020; however, in light of the Supreme Court's decision to hear HollyFrontier's appeal of the 
Tenth  Circuit  decision,  this  case  was  stayed  pending  a  decision  from  the  Supreme  Court.  In  December  2020,  various 
subsidiaries of HollyFrontier also filed a petition for review in the DC Circuit challenging the EPA's denial of small refinery 
exemption petitions for years prior to 2016. The petition was consolidated with petitions from eight other refining companies 
challenging  the  same  decision.  In  light  of  the  Supreme  Court's  decision  to  hear  HollyFrontier's  appeal  of  the  Tenth  Circuit 
decision, this case was stayed pending a decision from the Supreme Court. We are unable to estimate the costs we may incur, if 
any, at this time. It is too early to assess how the matter currently on appeal to the U.S. Supreme Court will impact future small 
refinery exemptions or whether the remaining cases are expected to have any impact on us.

We have been party to multiple proceedings before the Federal Energy Regulatory Commission (“FERC”) challenging the rates 
charged by SFPP, L.P. (“SFPP”) on its East Line pipeline facilities from El Paso, Texas to Phoenix, Arizona. In March 2018, 
FERC ruled that SFPP, as a master limited partnership, was prohibited from including an allowance for investor income taxes 
in the cost of service underlying its East Line rates. We reached a negotiated settlement with SFPP that provides for a payment 
to us of $51.5 million. FERC approved the settlement on December 31, 2020 subject to a rehearing period that resulted in a 
settlement  effective  date  of  February  2,  2021.  Under  the  terms  of  the  settlement  agreement,  SFPP  made  the  $51.5  million 
payment to us on February 10, 2021. As of December 31, 2020, we had no enforceable right to collect any of the settlement. 
Accordingly, recognition of a gain occurred when the uncertainties were resolved, and we held an enforceable right to collect 
on February 2, 2021.

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 2021 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 2021 through 2039. At December 31, 2020, the minimum 
future transportation and storage fees under transportation agreements having terms in excess of one year are as follows:

the  years  ended  December  31,  2020,  2019  and  2018,  respectively.  These  amounts  do  not  include  contractual  commitments

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 the Corporate, Other and Eliminations column.

The Refining segment represents the operations of the El Dorado, Tulsa, Navajo 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 geographic regions of the United States. HFC Asphalt operates 
various asphalt terminals in Arizona, New Mexico and Oklahoma. The Refining segment also included the operations of the 
Cheyenne Refinery until it permanently ceased petroleum refining operations during the third quarter of 2020.

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 and Red Giant Oil, one of the largest suppliers of locomotive engine 
oil in North America. Also, effective with our acquisition that closed February 1, 2019, the Lubricants and Specialty Products 
segment  includes  Sonneborn,  a  producer  of  specialty  hydrocarbon  chemicals  such  as  white  oils,  petrolatums  and  waxes  with 
manufacturing facilities in the United States and Europe..

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 refinery processing units in the Mid-
Continent,  Southwest  and  Rocky  Mountain  geographic  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, the 
Cheyenne  Pipeline  and  Cushing  Connect.  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.

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, or

processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and

disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2020.

Changes  in  internal  control  over  financial  reporting.    There  have  been  no  changes  in  our  internal  control  over  financial
