DeAr StockholDerS

2011 was a year of exceptional achievement at HollyFrontier. We completed our merger, generated record earnings, delivered 
strong operating performance at our refineries and significantly increased dividends paid to stockholders. 

HollyFrontier was created through the highly strategic and synergistic merger of Holly Corporation and Frontier Oil Corporation, 
which was completed on July 1, 2011. The transaction combined two of the most profitable and highest return-on-capital refiners 
in the independent refining sector, establishing HollyFrontier as a stronger and more geographically diversified refining company. 
Today, with our outstanding and complementary assets in the Mid-Continent, Southwest and Rocky Mountain Regions, the 
Company is well-positioned for continued growth and shareholder value creation.  

we have set our sights on being “the premier u.S. petroleum refining, pipeline and terminal company.” this objective 
spans a variety of important areas, including:

•   operating our assets safely, reliably and in an environmentally responsible way

•	 Leveraging	our	existing	assets	to	create	value

•	 Providing	our	customers	with	superior	products	and	service

•	 Seeking	to	grow	our	business	in	a	way	that	builds	long-term	shareholder	value	while	also	generating	near-term	returns

In addition to completing our merger during 2011, we capitalized on the very attractive market opportunity that resulted from 
depressed inland crude prices associated with higher oil production in the U.S. and Canada. Our record financial results in 2011 
included total net income of $1,023 million, earnings per share of $6.42 and free cash flow per share of $6.05. 

The Company’s outstanding financial performance reflects two fundamental attributes that differentiate HollyFrontier: First, 
our focused investment in Mid-Continent, Southwest and Rocky Mountain refining capacity paid off as higher crude production 
in these regions created advantaged pricing for local refiners. Second, because of our facility upgrade and expansion projects 
and commitment to operational excellence, our refining system delivered very strong throughput and product yields through 
many months of high-margin opportunity.

Following the merger, an initial key activity was to develop and articulate a business strategy that would help focus our attention 
and resources. This process benefitted greatly from the experiences gained at the legacy companies, which both had lengthy 
track records of managing through business cycles, investing capital in disciplined but productive manners and generating 
solid returns for shareholders. 

looking forward, we have a conservative bias, an opportunistic outlook and a business strategy that involves:

•	 	Exploiting	our	geographic	position	relative	to	increasing	crude	supplies	and	niche	product	markets

•	 	Investing	in	our	refineries	and	logistics	assets	to	further	enhance	our	competitive	position	and	improve	our	overall	 

refining margins

•	 	Maintaining	disciplined	capital	spending	and	emphasizing	the	return	of	capital	to	shareholders

•	 	Creating	even	stronger	operations	by	linking	our	refineries	logistically	and	sharing	best	practices

•	 	Partnering	with	Holly	Energy	Partners	(our	MLP	affiliate)	to	create	additional	value	by	connecting	our	refineries,	 

crude supply points and product market opportunities

HollyFrontier’s capital structure is a differentiating strength, and at December 31, 2011 we were the sole U.S. independent 
refiner with cash in excess of debt outstanding. This is due to two factors. First, we maintain a strong and liquid balance sheet  
to provide flexibility to address industry cyclicality, volatile working capital needs and strategic opportunities. Second, we  
participated in an outstanding margin environment during 2011 and generated substantial cash, most of which remained  
on our balance sheet at year end.

Quantitatively (and including Frontier Oil free cash flow for Q1 and Q2), our operating cash flow for the year exceeded capital 
expenditures by $1.3 billion. Our year-ending balance sheet reflected cash of $1.8 billion, and debt (excluding non-recourse 
HEP debt) of $689 million. We also held 11.1 million limited partnership units of Holly Energy Partners, which closed the year 
with a $53.78 value per unit, and our HEP General Partner interest, which received distributions of $16 million during 2011. 

HollyFrontier is well positioned and is committed to returning value to shareholders, while investing in our business and managing 
through the business cycles we encounter in the downstream petroleum sector. Distributions to stockholders during 2011 included 
two special dividends and a 33% increase in our regular dividend rate. In addition, we repurchased 1.3 million shares and 
affected a two-for-one split of HollyFrontier common stock. The Board of Directors has established a new policy for the combined 
Company regarding the return of capital to shareholders, under which we plan to grow our regular dividends progressively  
and pay special cash dividends as we deem appropriate based on available liquidity and other investment opportunities. We 
will also repurchase shares opportunistically and to offset dilution from our stock-based compensation programs. We believe 
this combination of tools, used in differing quantities as dictated by the business environment, will allow us to maximize shareholder 
returns, both in the form of price appreciation and cash yield.

We are proud of HollyFrontier and all that we achieved in 2011. The headline event, from a corporate standpoint, was completion 
of our merger. This transaction went far beyond a change of name and ticker symbol; it created a stronger company that faces 
new and exciting opportunities as we work to rationalize, improve and grow. 

In addition, we have taken a number of initiatives to improve and expand our operations. Our recently-announced expansion  
of our Woods Cross Refinery and associated Utah Black Wax crude supply arrangement showcases the type of organic growth 
we are successfully achieving. The Woods Cross project capitalizes on our existing capabilities and infrastructure while facili-
tating volume growth that will develop in parallel with Utah crude oil production, effectively displacing foreign imported crude 
with cost effective domestic Utah crude oil. We believe opportunities like this will further bolster our competitive position, 
grow our business and generate attractive cash returns. 

Our UNEV pipeline, which connects the Wood Cross Refinery to the Las Vegas market, is now fully operational. We expect  
the access afforded by this pipeline to offer an attractive outlet for current and expanding Woods Cross Refinery production 
and other Rocky Mountain refiners at economic transportation costs, driving profits in years to come.

HollyFrontier’s outstanding operational performance and value creating potential are built on the dedication of the Company’s  
talented employees. Their efforts have enabled HollyFrontier to maintain and improve our operations across our asset base 
and to execute on our growth strategy. We extend our deepest appreciation and thanks to our employees for their service and 
continued hard work. 

We also extend heartfelt thanks to our stockholders for their investment and confidence in HollyFrontier Corporation, to our 
trading partners for relationships that sustain our business, and to the communities that host our operations, enabling the 
development of our Company and the careers of our people. 

This is an exciting time for HollyFrontier, and we are optimistic about the Company’s future. We look forward to meeting and  
exceeding our operational goals and executing on our business strategy to continue enhancing value for HollyFrontier stockholders.

FORWARD-LOOKING STATEMENTS 

PART I 

This Annual Report on Form 10-K contains certain “forward-looking statements” within the meaning of the federal 
securities laws.  All statements, other than statements of historical fact included in this Form 10-K, including, but 
not  limited  to,  those  under  “Business  and  Properties”  in  Items  1  and  2,  “Risk  Factors”  in  Item  1A,  “Legal 
Proceedings”  in  Item  3  and  “Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of 
Operations”  in  Item  7,  are  forward-looking statements.    These  statements  are  based on  management’s  beliefs  and 
assumptions  using  currently  available  information  and  expectations  as  of  the  date  hereof,  are  not  guarantees  of 
future performance and involve certain risks and uncertainties.  Although we believe that the expectations reflected 
in  these  forward-looking  statements  are  reasonable,  we  cannot  assure  you  that  our  expectations  will  prove  to  be 
correct.  Therefore, actual outcomes and results could materially differ from what is expressed, implied or forecast

• 
• 
•  our efficiency in carrying out construction projects; 
•  our  ability  to  acquire  refined  product  operations  or pipeline  and  terminal  operations  on  acceptable  terms 

and to integrate any existing or future acquired operations; 
the possibility of terrorist attacks and the consequences of any such attacks; 

• 
•  general economic conditions;  
•  our ability to realize fully or at all the anticipated benefits of our “merger of equals” with Frontier; and 
•  other financial, operational and legal risks and uncertainties detailed from time to time in our Securities and 

Exchange Commission filings. 

Cautionary  statements  identifying  important  factors  that  could  cause  actual  results  to  differ  materially  from  our 
expectations  are  set  forth  in  this  Form  10-K,  including without  limitation  the  forward-looking  statements  that  are 
referred to above.  When considering forward-looking statements, you should keep in mind the risk factors and other 
cautionary  statements  set  forth  in  this  Form  10-K  under  “Risk  Factors”  in  Item  1A  and  in  conjunction  with  the 
discussion  in  this  Form  10-K  in  “Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of 
Operations” under the heading “Liquidity and Capital Resources.”  All forward-looking statements included in this 
Form 10-K and all subsequent written or oral forward-looking statements attributable to us or persons acting on our 
behalf  are  expressly  qualified  in  their  entirety  by  these  cautionary  statements.    The  forward-looking  statements 
speak only as of the date made and, other than as required by law, we undertake no obligation to publicly update or 
revise any forward-looking statements, whether as a result of new information, future events or otherwise.

high octane stocks produced to make various grades of gasoline. 

“PPM” means parts-per-million. 

“Paraffinic oil” is a high paraffinic, high gravity oil produced by extracting aromatic oils and waxes from gas 

oil and is used in producing high-grade lubricating oils. 

“Refinery gross margin” means the difference between average net sales price and average product costs per 

produced barrel of refined products sold.  This does not include the associated depreciation and amortization costs. 

“Reforming”  means  the  process  of  converting  gasoline  type  molecules  into  aromatic,  higher  octane  gasoline 

blend stocks while producing hydrogen in the process. 

“Roofing flux” is produced from the bottom cut of crude oil and is the base oil used to make roofing shingles 

for the housing industry. 

“RFS2” or advanced renewable fuel standard is a regulatory mandate required by the Energy Independence and 
Security  Act  of  2007  that  requires  36  billion  gallons  of  renewable  fuel  to  be  blended  into  transportation  fuels  by 
2022.  New mandated blending requirements for this standard became effective July 1, 2010.  

“ROSE,” or “Solvent deasphalter / residuum oil supercritical extraction,” means a refinery unit that uses a 
light hydrocarbon like propane or butane to extract non-asphaltene heavy oils from asphalt or atmospheric reduced 
crude.  These deasphalted oils are then further converted to gasoline and diesel in the FCC process.  The remaining

Items 1 and 2.  Business and Properties 

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  (“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  merged  with  Frontier  Oil  Corporation  (“Frontier”)  effective  July  1,  2011.    Concurrent  with  the  merger,  we 
changed  our  name  from  Holly  Corporation  (“Holly”)  to  HollyFrontier  and  changed  the  ticker  symbol  for  our 
common stock traded on the New York Stock Exchange to “HFC.”  Accordingly, this document includes Frontier, 
its  consolidated  subsidiaries  and  the  operations  of  the  merged  Frontier  businesses  effective  July  1,  2011,  but  not 
prior to this date. 

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 filings at the SEC website is available on our website on the Investors 
page.  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.”  

On February 21, 2011, we entered into a merger agreement providing for a “merger of equals” business combination 
between  us  and  Frontier  for  purposes  of  creating  a  more  diversified  company  having  a  broader  geographic  sales 
footprint, stronger financial position and to create a more efficient corporate overhead structure, while also realizing 
synergies and promoting accretion to earnings per share. The legacy Frontier business operations consist of crude oil 
refining  and  the  wholesale  marketing  of  refined  petroleum  products.  Frontier  operated  refineries  in  Cheyenne, 
Wyoming (the “Cheyenne Refinery”) and El Dorado, Kansas (the “El Dorado Refinery”) that serve markets in the 
Rocky Mountain and Plains States regions of the United States. The combined annual average crude oil capacity of 
these refineries is approximately 187,000 barrels per day. On July 1, 2011, North Acquisition, Inc., a direct wholly-
owned subsidiary of Holly, merged with and into Frontier, with Frontier surviving as a wholly-owned subsidiary of 
Holly.  Subsequent to the merger and following approval by HollyFrontier’s post-closing board of directors, Frontier 
merged with and into HollyFrontier, and HollyFrontier continued as the surviving corporation. The aggregate equity 
consideration paid in connection with the merger was $3.7 billion.   

On June 1, 2009, we acquired an 85,000 BPSD refinery located in Tulsa, Oklahoma (the “Tulsa West facility”) from 
an affiliate of Sunoco, Inc. (“Sunoco”) for $157.8 million.  On October 20, 2009, we sold a portion of the acquired 
crude oil petroleum storage tanks and certain refining-related crude oil receiving pipeline facilities to an affiliate of 
Plains All American Pipeline, L.P. (“Plains”) for $40 million.

On December 1, 2009, we acquired a 75,000 BPSD refinery from an affiliate of Sinclair Oil Company (“Sinclair”) 
also  located  in  Tulsa,  Oklahoma  (the  “Tulsa  East  facility”)  for  $183.3  million.    We  have  integrated  certain 
operations  of  the  Tulsa  West  and  East  facilities  (collectively,  the  “Tulsa  Refineries”).    This  resulted  in  the  Tulsa 
Refineries having an integrated crude processing rate of 125,000 BPSD.  

On February 29, 2008, we sold certain assets to HEP consisting of crude oil pipelines, tankage and terminal facilities 
supporting our Navajo and Woods Cross Refineries.   HEP is a variable interest entity (“VIE”) as defined under U.S. 
generally accepted accounting principles (“GAAP”).  Under GAAP, HEP’s acquisition of these assets qualified as a 
reconsideration  event  whereby  we  reassessed  our  beneficial  interest  in  HEP.    Following  this  transaction,  we 
determined that our beneficial interest in HEP exceeded 50%.  Therefore, we reconsolidated HEP effective March 1, 
2008.  Intercompany transactions with HEP are eliminated in our consolidated financial statements.   

HEP made a number of acquisitions in 2009 through 2011.  Information on these acquisitions can be found under 
the  “Holly  Energy  Partners,  L.P.”  section  provided  later  in  this  discussion  of  Items  1  and  2,  “Business  and 
Properties.”  

As of December 31, 2011, we: 

• 

• 

• 

• 

• 

owned and operated the El Dorado Refinery located in El Dorado, Kansas, two refinery facilities located in 
Tulsa, Oklahoma (collectively, the “Tulsa Refineries”), a refinery in Artesia, New Mexico that is operated 
in conjunction with crude oil distillation and vacuum distillation and other facilities situated 65 miles away 
in  Lovington,  New  Mexico  (collectively,  the  “Navajo  Refinery”),  a  refinery  located  in  Cheyenne, 
Wyoming (“the Cheyenne Refinery”) and a refinery in Woods Cross, Utah (the “Woods Cross Refinery”); 
owned  and  operated  NK  Asphalt  Partners  (“NK  Asphalt”)  which  operates  various  asphalt  terminals  in 
Arizona and New Mexico; 
owned  a  75%  interest  in  a  12-inch  refined  products  pipeline  from  Salt  Lake  City,  Utah  to  Las  Vegas, 
Nevada, together with terminal facilities in the Cedar City, Utah and North Las Vegas areas (the “UNEV 
Pipeline”); 
owned  Ethanol  Management  Company  (“EMC”),  a  products  terminal  and  blending  facility  near  Denver, 
Colorado and a 50% interest in Sabine Biofuels II, LLC (“Sabine Biofuels”), a development stage biodiesel 
production facility located in Port Arthur, Texas; and 
owned  a  42%  interest  in  HEP  which  includes  our  2%  general  partner  interest.    HEP  owns  and  operates 
logistic  assets  consisting  of  petroleum  product  and  crude  oil  pipelines  and  terminal,  tankage  and  loading 
rack  facilities  that  principally  support  our  refining  and  marketing  operations  in  the  Mid-Continent, 
Southwest and Rocky Mountain regions of the United States and Alon USA, Inc.’s (“Alon”) refinery in Big 
Spring, Texas.  Additionally, HEP owns a 25% interest in SLC Pipeline LLC (“SLC Pipeline”), a 95-mile 
intrastate pipeline system that serves refineries in the Salt Lake City area. 

Our  operations  are  currently  organized  into  two  reportable  segments,  Refining  and  HEP.    The  Refining  segment 
includes the operations of our El Dorado, Tulsa, Navajo, Cheyenne and Woods Cross Refineries and NK Asphalt.  
The HEP segment involves all of the operations of HEP effective March 1, 2008 (date of reconsolidation).  

REFINERY OPERATIONS  

Our refinery operations serve the Mid-Continent, Southwest and Rocky Mountain regions of the United States. We 
own and operate five complex refineries having an aggregate crude capacity of 443,000 barrels per day.  Each of our 
refineries has the complexity to convert discounted, heavy and sour crude oils into a high percentage of gasoline, 
diesel  and  other  high-value  refined  products.    For  2011,  gasoline,  diesel  fuel,  jet  fuel  and  specialty  lubricants 
(excluding  volumes  purchased  for  resale)  represented  48%,  32%,  5%  and  3%,  respectively,  of  our  total  refinery 
sales volumes. 

The  following  tables  below  and  elsewhere  in  this  discussion  of  our  refinery  operations  set  forth  information, 
including non-GAAP performance measures, about our refinery operations.  The cost of products and refinery gross 
margin do not include the effect of 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.

Mid-Continent Region (Tulsa and El Dorado Refineries) 

Facilities 
On June 1, 2009, we acquired the Tulsa West facility, an 85,000 BPSD refinery in Tulsa, Oklahoma from Sunoco.  
On  December  1,  2009,  we  acquired  the  Tulsa  East  facility,  a  75,000  BSPD  refinery  that  is  also  located  in  Tulsa, 
Oklahoma from Sinclair.  We have integrated certain refining processes between our Tulsa West and East facilities.  
In September 2011, HEP completed the Tulsa interconnecting pipeline project which facilitated a combined crude 
processing rate of 125,000 BPSD.  On July 1, 2011, the merger with Frontier added the El Dorado Refinery with a 
135,000 BSPD capacity.   The El Dorado Refinery is a high-complexity coking refinery with the ability to process 
significant  volumes  of  heavy  and  sour  crudes.    For  2011,  gasoline,  diesel  fuel,  jet  fuel  and  specialty  lubricants 
(excluding  volumes  purchased for resale) represented 44%, 32%, 7%  and  6%, respectively,  of our Mid-Continent 
sales volumes.

The El Dorado Refinery is located on 1,100 acres south of El Dorado, Kansas and is a fully integrated refinery. The 
principal process units at the El Dorado Refinery consist of crude and vacuum distillation; hydrodesulfurization of 
naphtha,  kerosene,  diesel,  and  gas  oil  streams;  isomerization;  catalytic  reforming;  aromatics  recovery;  catalytic 
cracking;  alkylation;  delayed  coking;  hydrogen  production;  and  sulfur  recovery.  Refining  operations  began  at  the 
site in 1917 and the operating units now present include both newly constructed units and older units that have been 
upgraded  over  the  years.    Supporting  infrastructure  includes  maintenance  shops,  warehouses,  office  buildings,  a 
laboratory, utility facilities, and a wastewater plant (“Supporting Infrastructure”) and logistics assets owned by HEP, 
which includes approximately 3.7 million barrels of tankage, a truck sales terminal, and a propane terminal.  The 
facility  typically  processes  approximately  135,000  BPSD  of  crude  oil  with  the  capability  to  handle  a  significant 
volume of heavy sour crudes. 

The Tulsa West facility is located on a 750-acre site in Tulsa, Oklahoma situated along the Arkansas River.  The 
principal  process  units  at  the  Tulsa  West  facility  consist  of  crude  distillation  (with  light  ends  recovery),  naphtha 
hydrodesulfurization,  catalytic  reforming,  propane  de-asphalting,  lubes  extraction,  MEK  dewaxing,  delayed  coker 
and butane splitter units.  Most of the operating units at the facility currently in service were built in the late 1950s 
and  early  1960s.    The  refinery  was  reconfigured  to  emphasize  specialty  lubricant  production  in  the  early  1990s.  
Tulsa West facility’s Supporting Infrastructure includes approximately 3.2 million barrels of feedstock and product 
tankage, of which 0.4 million barrels of tankage is owned by Plains, and an additional 1.2 million barrels of tank 
capacity is currently out of service but could be made available for future use.  

The Tulsa East facility is located on a 466-acre site also in Tulsa, Oklahoma situated along the Arkansas River.  The 
principal  process  units  at  the  Tulsa  East  facility  consist  of  crude  distillation,  naphtha  hydrodesulfurization,  FCC, 
isomerization,  catalytic  reforming,  alkylation,  scanfiner,  diesel  hydrodesulfurization  and  sulfur  units.    The  Tulsa 
East  facility’s  Supporting  Infrastructure  includes  approximately  3.75 million  barrels  of  tankage  capacity  on  the 
refinery’s premises, of which approximately 3.4 million barrels of tankage is owned by HEP.  

In  2011,  we  integrated  certain  Tulsa  refining  operations  and  through  this  process  now  have  a  highly  complex 
refining operation with a combined crude processing rate of approximately 125,000 BPSD.   

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.

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.  Although our Gulf Coast competitors typically have 
lower  production  costs  because  of  economies  of  scale,  we  believe  that  our  competitors’  higher  refined  product 
transportation costs allow our El Dorado Refinery to compete effectively in the Plains States and Rocky Mountain 
region with the Gulf Coast refineries.   

For the period July 1, 2011 to December 31, 2011, sales to Shell represented approximately 50% of the El Dorado 
Refinery’s  total  sales  and  10%  of  our  total  consolidated  sales.  We  have  an  offtake  agreement  with  Shell  Oil 
Products  US  (“Shell”)  under  which  Shell  purchases  gasoline  and  diesel  production  of  the  El  Dorado  Refinery  at 
market-based prices through December 2014.  Shell also has agreed to purchase all jet fuel production until the end 
of the product offtake agreement.   In aggregate during 2011, we retained and marketed  60,000 bpd of the refinery’s 
gasoline and diesel production while the remaining production was sold to Shell.  We market gasoline and diesel in 
the  same  markets  where  Shell  sells  the  refinery’s  products,  primarily  in  Denver  and  throughout  the Plains  States. 
Upon  expiration  of  the  offtake  agreement,  we  intend  to  sell  the  gasoline  and  diesel  produced  by  the  El  Dorado 
Refinery in the same general markets served by Shell. 

The Tulsa Refineries primarily serve the Mid-Continent region of the United States.  Distillates and gasolines are 
primarily delivered from the Tulsa Refineries to market via two 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.  

In conjunction with our acquisition of the Tulsa East facility, we entered a five-year offtake agreement through 2014 
with  an  affiliate  of  Sinclair  whereby  Sinclair  agreed  to  purchase  45,000  to  50,000  BPD  of  gasoline  and  distillate 
products at market prices from us to supply its branded and unbranded marketing network throughout the Midwest.  
Upon expiration, the offtake agreement can be renewed by Sinclair for an additional five-year term.  For the year 
ended December 31, 2011, sales to Sinclair represented approximately 40% of the Tulsa Refineries total sales and 
13% of our total consolidated sales. 

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

Our Tulsa West facility also produces specialty lubricant products sold in both commercial and specialty  markets 
throughout  the  United  States  and  to  customers  with  operations  in  Central  America  and  South  America.    The 
specialty  lubricant  products are  high  value  products  that  provide  a  significantly  higher  margin  contribution  to  the 
refinery.    Base  oil  customers  include  blender-compounders  who  prepare  the  various  finished  lubricant  and  grease 
products sold to end users.  Agricultural oils, primarily formulated as supplemental carriers for herbicides, are sold 
to product formulators.  Process oil customers include rubber and chemical industry customers.  Specialty waxes are 
sold primarily to packaging customers as coating material for paper and cardboard, and to non-packaging customers 
in the construction materials, adhesive and candle-making markets.  Our production represents approximately 6% of 
paraffinic oil capacity and 9% of wax production capacity in the United States market and is one of four refineries of 
specialty aromatic oils in North America.

Crude Oil and Feedstock Supplies 
The  El  Dorado  Refinery  is  located  about  125  miles,  and  the  Tulsa  Refineries  are  located  approximately  50 miles 
from Cushing, Oklahoma, a significant crude oil pipeline trading and storage hub.  Local pipelines provide direct 
access to regional Oklahoma crude production as well as access to United States onshore, Gulf of Mexico, Canadian 
and  other  foreign  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.  

Both  our  Mid-Continent  Refineries  are  connected  via  pipeline  to  Cushing,  Oklahoma.    In  addition,  we  have  a 
transportation  services  agreement  to  transport  up  to  38,000  bpd  of  crude  oil  on  the  Spearhead  Pipeline  from 
Flanagan,  Illinois  to  Cushing,  Oklahoma,  enabling  us  to  transport  Canadian  crude  oil  to  Cushing  for  subsequent 
shipment  to  either of our  Mid-Continent  Refineries  or  to our Navajo  Refinery.  The  initial  term  of  this  agreement 
expires in 2016.  We have the right to extend the agreement for an additional ten years and to increase the volume 
transported under a preferential tariff to 50,000 bpd. 

Southwest Region (Navajo Refinery) 

Facilities 
The Navajo Refinery has a crude oil capacity of 100,000 BPSD and has the ability to process sour crude oils into 
high  value  light  products  such  as  gasoline,  diesel  fuel  and  jet  fuel.    For  2011,  gasoline,  diesel  fuel  and  jet  fuel 
(excluding  volumes  purchased  for  resale)  represented  52%,  34%  and  1%,  respectively,  of  our  Southwest  sales

The Navajo Refinery’s Artesia, New Mexico facility is located on a 561-acre site and is a fully integrated refinery 
with  crude  distillation,  vacuum  distillation,  FCC,  ROSE  (solvent  deasphalter),  HF  alkylation,  catalytic  reforming, 
hydrodesulfurization, mild hydrocracking, isomerization, sulfur recovery and product blending units.  The operating 
units at the Artesia facility include newly constructed units, older units that have been relocated from other facilities 
and  upgraded  and  re-erected  in  Artesia,  and  units  that  have  been  operating  as  part  of  the  Artesia  facility  (with 
periodic  major  maintenance)  for  many  years,  in  some  very  limited  cases  since  before  1970.    Supporting 
Infrastructure  includes  approximately  2  million  barrels  of  feedstock  and  product  tankage,  of  which  0.2  million 
barrels of tankage are owned by HEP.   

 The  Artesia  facility  is  operated  in  conjunction  with  a  refining  facility  located  in  Lovington,  New  Mexico, 
approximately  65  miles  east  of  Artesia.    The  principal  equipment  at  the  Lovington  facility  consists  of  a  crude 
distillation unit and associated vacuum distillation units that were constructed after 1970.  Supporting Infrastructure 
includes 1.1 million barrels of feedstock and product tankage of which 0.2 million barrels of tankage are owned by 
HEP.  The Lovington facility processes crude oil into intermediate products that are transported to Artesia by means 
of  three  intermediate  pipelines  owned  by  HEP.    These  products  are  then  upgraded  into  finished  products  at  the 
Artesia facility.  The combined crude oil capacity of the Navajo Refinery facilities is 100,000 BPSD and it typically 
processes or blends an additional 10,000 BPSD of natural gasoline, butane, gas oil and naphtha.  

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

El Paso Market 
The  El  Paso  market  for  refined  products  is  currently  supplied  by  a  number  of  area  and  gulf  coast  refiners  and 
pipelines.    Area  refiners  include  Navajo,  WRB  Refining,  LLC  (“WRB”)  (a  joint  venture  between  ConocoPhillips 
and  EnCana  Corp.),  Valero,  Alon  (“Alon”),  and  Western  Refining.    Pipelines  serving  this  market  are  owned  by 
Magellan  Midstream  Partners,  L.P. (“Magellan”),  NuStar Energy  L.P.  and HEP.    Refined products  from  the  Gulf 
Coast are transported via Magellan pipelines, including Magellan’s Longhorn Pipeline acquired in 2009.   

Arizona Market 
The  Arizona  market  for  refined  products  is  currently  supplied  by  a  number  of  refiners  via  pipelines  and  trucks.  
Refiners include companies located in west Texas, eastern New Mexico, northern New Mexico, the Gulf Coast and 
the West Coast.  Magellan’s Longhorn Pipeline delivers refined products utilizing a direct route from the Texas Gulf 
Coast to El Paso and, through interconnections with third-party common carrier pipelines, into the Arizona market.

New Mexico Markets 
The Artesia, Albuquerque, Moriarty and Bloomfield markets are supplied by a number of refiners via pipelines and 
trucks.  Refiners include Navajo, Valero, Western Refining, Alon and WRB.  

We use a common carrier pipeline out of El Paso to serve the Albuquerque market.  In addition, HEP leases from 
Mid-America  Pipeline  Company,  L.L.C.,  a  pipeline  between  White  Lakes,  New  Mexico  and  the  Albuquerque 
vicinity and Bloomfield, New Mexico.  The lease agreement currently runs through 2017, and HEP has options to 
renew for two ten-year periods.  HEP owns and operates a 12-inch pipeline from the Navajo Refinery to the leased 
pipeline as well as terminalling facilities in Bloomfield, New Mexico, which is located in the northwest corner of 
New  Mexico,  and  in  Moriarty,  which  is  40  miles  east  of  Albuquerque.    These  facilities  permit  us  to  ship  light 
products  to  the  Albuquerque  and  Santa  Fe,  New  Mexico  areas,  which  have  historically  experienced  high  growth 
rates.  If needed, additional pump stations could further increase the pipeline’s capabilities.

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,  our  tank  trucks  and  through  third-party  crude  oil  pipeline  systems  for 
delivery to the Navajo Refinery.     

The  Navajo  Refinery  also  has  access  to  a  wide  variety  of  crude  oils  available  at  Cushing,  Oklahoma  via  HEP’s 
Roadrunner  Pipeline  that  connects  to  Centurion  Pipeline  L.P.  and  Spearhead  Pipeline  at  Cushing  Oklahoma.    In 
2010, the Navajo Refinery began processing heavy sour crude oil transported from Cushing through these pipelines.   

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 oil companies for use as feedstock. 

Rocky Mountain Region (Cheyenne and Woods Cross Refineries) 

Facilities 
The  Cheyenne  Refinery  has  a  crude  oil  capacity  of  52,000  BPSD  and  the  Woods  Cross  Refinery  has  a  crude  oil 
capacity of 31,000 BPSD.  The Cheyenne Refinery processes heavy Canadian crudes as well as local sweet crudes 
such as that produced from the Bakken shale and similar resources.  The Woods Cross Refinery processes regional 
sweet and black wax crude as well as Canadian sour crude oils into high value light products.  For 2011, gasoline, 
diesel fuel and jet fuel (excluding volumes purchased for resale) represented 56%, 31% and 1%, respectively, of our 
Rocky Mountain sales volumes.

The Cheyenne Refinery facility is located on a 255- acre site and is a fully integrated refinery with crude distillation, 
vacuum  distillation,  coking,  FCCU,  HF  alkylation,  catalytic  reforming,  hydrodesulfurization  of  naphtha  and 
distillates,  butane  isomerization,  hydrogen  production,  sulfur  recovery  and  product  blending  units.   The  operating 
units at the Cheyenne Refinery include both newly constructed units and older units that have been upgraded over 
the years.  Supporting Infrastructure includes approximately 1.6 million barrels of feedstock and product tankage, of 
which 1.5 million barrels of tankage are owned by HEP.  

The  Woods  Cross  Refinery  facility  is  located  on  a  200-acre  site  and  is  a  fully  integrated  refinery  with  crude 
distillation, solvent deasphalter, FCC, HF alkylation, catalytic reforming, hydrodesulfurization, isomerization, sulfur 
recovery and product blending units.  The operating units at the Woods Cross Refinery include newly constructed 
units, older units that have been relocated from other facilities, upgraded and re-erected in Woods Cross, and units 
that have been operating as part of the Woods Cross facility (with periodic major maintenance) for many years, in 
some very limited cases since before 1950.  Supporting Infrastructure includes approximately 1.5 million barrels of 
feedstock and product tankage, of which 0.2 million barrels of tankage are owned by HEP.  The facility typically 
processes or blends an additional 2,000 BPSD of natural gasoline, butane and gas oil over its 31,000 BPSD capacity.  

We  own  and  operate  4  miles  of  hydrogen  pipeline  that  connects  the  Woods  Cross  Refinery  to  a  hydrogen  plant 
located  at  Chevron’s  Salt  Lake  City  Refinery.    Additionally,  HEP  owns  and  operates  12  miles  of  crude  oil  and 
refined products pipelines that allows us to connect our Woods Cross Refinery to common carrier pipeline systems. 

We plan to expand the Woods Cross refinery capacity to 45,000 BPSD at a cost of approximately $225 million. The 
expansion is expected to be completed in late 2014.  The expansion scope includes the relocation / revamp of crude, 
fluid  catalytic  cracking,  and  polymerization  units  from  a  subsidiary  of Western  Refining  Inc.'s (“Western”) 
Bloomfield,  New  Mexico  refinery  to  Woods  Cross  as  well  an  expansion  of  the  Woods  Cross  diesel  hydrotreater.  
We have signed a definitive agreement with Western for the purchase of the Bloomfield units.

In  conjunction  with  the  expansion,  we  signed  a  10-year,  20,000  bpd  crude  oil  supply  agreement  with  Newfield 
Exploration Company.  This agreement, which commences upon completion of the expansion, will supply black and 
yellow wax crude oil produced in the nearby Uinta Basin region to the Woods Cross Refinery, which currently has 
capacity to process approximately 10,000 bpd of these crudes.  Upon completion of this expansion, the Woods Cross 
Refinery  will  be  able  to  process  approximately  24,000  bpd  of  waxy  Utah  crudes.   This  expansion  and  crude  oil 
supply  agreement,  and  expected  completion  timeline,  are  subject  to  HollyFrontier  successfully  obtaining  the 
necessary permits and regulatory approvals.  

Markets and Competition  
The Cheyenne Refinery primarily markets its products in eastern Colorado, including metropolitan Denver, eastern 
Wyoming and western Nebraska. Because of the location of the Cheyenne Refinery, we are able to sell a significant 
portion  of  its  diesel  from  the  truck  rack  at  the  refinery,  thus  eliminating  transportation  costs.  Pipeline  shipments 
from the Cheyenne Refinery are on the Plains pipeline serving Denver and Colorado Springs, Colorado and HEP’s 
pipeline to Sidney Nebraska.  

Denver Market 
The  most  competitive  market  for  the  Cheyenne  Refinery  is  the  Denver  metropolitan  area.  Three  other  refineries 
supply the Denver market, a refinery near Rawlins and one in Casper, both in Wyoming and owned by Sinclair and 
a refinery in Denver owned by Suncor. Five product pipelines also supply Denver, including three from outside the 
region. Typically products shipped in from other regions bear higher transportation costs. The Suncor refinery has 
lower product transportation costs than we do; however, we have lower crude oil transportation costs because the 
Cheyenne Refinery is located 88 miles south of Guernsey, Wyoming, the main hub and crude oil trading center for 
the  Rocky  Mountain  region.  Moreover,  unlike  Sinclair  and  Suncor,  we  only  sell  our  products  to  the  wholesale 
market. We believe this gives us an advantage because all of the Cheyenne Refinery’s principal competitors have 
retail outlets and we do not directly compete with independent retailers of gasoline and diesel. 

Utah Market 
The Woods Cross Refinery’s primary market is Utah, which is  currently supplied  by a number of local refiners and 
the Pioneer Pipeline.  Local area refiners include Woods Cross, Chevron, Tesoro, Big West and Silver Eagle.  Other 
refiners that ship via the Pioneer Pipeline include Sinclair, ExxonMobil and ConocoPhillips.  We estimate that the 
four  refineries  that  compete  with  our  Woods  Cross  Refinery  have  a  combined  capacity  to  process  approximately 
150,000  BPD  of  crude  oil.    The  five  Utah  refineries  collectively  supply  an  estimated  70%  of  the  gasoline  and 
distillate  products  consumed  in  the  states  of  Utah  and  Idaho,  with  the  remainder  imported  from  refineries  in 
Wyoming and Montana via the Pioneer Pipeline owned jointly by Sinclair and ConocoPhillips.  Approximately 40% 
- 45% of the gasoline and diesel fuel produced by our Woods Cross Refinery is sold through a network of Phillips 
66 branded marketers under a long-term supply agreement. 

Idaho, Wyoming, Eastern Washington and Nevada Markets 
We  supply  a  small  percentage  of  the  refined  products  consumed  in  the  combined  Idaho,  Wyoming,  eastern 
Washington  and  Nevada  markets.    Our  Woods  Cross  Refinery  ships  refined  products  over  Chevron’s  common 
carrier pipeline system to numerous terminals, including HEP’s terminals at Boise and Burley, Idaho and Spokane, 
Washington  and  to  terminals  at  Pocatello  and  Boise,  Idaho  and  Pasco,  Washington  that  are  owned  by  Northwest 
Terminalling Pipeline Company.  We sell to branded and unbranded customers in these markets.   

We  have  historically  trucked  refined  products  to  Las  Vegas,  Nevada.    The  majority  of  the  Las  Vegas,  Nevada 
market for refined products is supplied by various West Coast refiners and suppliers via Kinder Morgan’s CalNev 
common carrier pipeline system.  See our discussion of the UNEV Pipeline below that will permit our Woods Cross 
Refinery  to  ship  significant volumes  of refined product  to  Cedar  City,  Utah  and  Las Vegas, Nevada  beginning  in 
2012.

Crude Oil and Feedstock Supplies 
Crude oil is transported to the Cheyenne Refinery from suppliers in Canada, Nebraska, North Dakota and Montana 
via common carrier pipelines owned by Kinder Morgan, Plains All American Pipeline and Suncor Energy, as well as 
by truck.  The Woods Cross Refinery currently obtains its supply of crude oil from suppliers in Canada, Wyoming, 
Utah and Colorado as delivered via common carrier pipelines that originate in Canada, Wyoming and Colorado.  In 
2009, we also began receiving crude oil via the SLC Pipeline, a joint venture common carrier pipeline in which HEP 
owns a 25% interest.  Supplies of black wax crude oil are shipped via truck.  

NK Asphalt Partners 

We  manufacture  and  market  commodity  and  modified  asphalt  products  in  Arizona,  New  Mexico,  Oklahoma, 
Kansas, Missouri, Texas and northern Mexico.  We have three manufacturing facilities located in Glendale, Arizona; 
Albuquerque,  New  Mexico;  and  Artesia,  New  Mexico.    Our  Albuquerque  and  Artesia  facilities  manufacture 
modified hot asphalt products and commodity emulsions from base asphalt materials provided by our refineries and 
third-party suppliers.  Our Glendale facility manufactures modified hot asphalt products from base asphalt materials 
provided by our refineries and third-party suppliers.  Our products are shipped via third-party trucking companies to 
commercial customers that provide asphalt based materials for commercial and government projects.  

Other Assets 

We own Ethanol Management Company, a 25,000 bpd products terminal and blending facility located near Denver, 
Colorado.    We  also  own  a  50%  joint  venture  interest  in  Sabine  Biofuels  II,  LLC,  a  30  million  gallon  per  year 
biodiesel production facility located near Port Arthur, Texas. 

UNEV Pipeline 

We own a 75% joint venture interest in the recently completed UNEV Pipeline, a 400 mile 12-inch refined products 
pipeline from Salt Lake City, Utah to Las Vegas, Nevada, together with terminal and ethanol blending facilities in 
the Cedar City, Utah and North Las Vegas areas and storage facilities at the Cedar City terminal with Sinclair, our 
joint  venture  partner,  owning  the  remaining  25%  interest.    The  pipeline  has  a  capacity  of  62,000  BPD  (based  on 
gasoline  equivalents),  and  has  the  capacity  for  further  expansion  to  120,000  BPD.    The  cost  of  constructing  this 
pipeline  including  terminals  and  ethanol  blending  and  storage  facilities  was  approximately  $410  million.    The 
pipeline  was  mechanically  complete  in  November  2011,  and  initial  start-up  activities  commenced  in  December 
2011. 

We have entered into a 10-year minimum annual revenue guaranty of $15.4 million per year per year on the UNEV 
Pipeline.  This entitles us to ship approximately 15,500 BPD of refined product at a lower incentive tariff rate.  We 
have  an  option  agreement  with  HEP  granting  them  an  option  to  purchase  all  of  our  equity  interests  in  this  joint 
venture  pipeline  at  a  purchase  price  equal  to  our  investment  in  this  joint  venture  pipeline  plus  interest  at  7%  per 
annum.

HOLLY ENERGY PARTNERS, L.P.  

In July 2004, we completed the initial public offering of limited partnership interests in HEP, a Delaware limited 
partnership that also trades on the New York Stock Exchange under the trading symbol “HEP.”  HEP was formed to 
acquire,  own  and  operate  substantially  all  of  the  refined  product  pipeline  and  terminalling  assets  that  support  our 
refining  and  marketing  operations  in  the  Mid-Continent,  Southwest  and  Rocky  Mountain  regions  of  the  United 
States.   

HEP owns and operates a system of petroleum product and crude oil pipelines in New Mexico, Oklahoma, Texas 
and Utah and distribution terminals and refinery tankage in Arizona, Idaho, Kansas, New Mexico, Oklahoma, Texas, 
Utah, Washington and Wyoming.  HEP generates revenues by charging tariffs for transporting petroleum products 
and  crude  oil  through  its  pipelines,  by  leasing  certain  pipeline  capacity  to  Alon  by  charging  fees  for  terminalling 
refined products and other hydrocarbons and storing and providing other services at its storage tanks and terminals.  
HEP  does  not  take  ownership  of  products  that  it  transports  or  terminals;  therefore,  it  is  not  directly  exposed  to 
changes in commodity prices.   

HEP’s recent acquisitions (2009 through 2011) are summarized below:  

2011 Acquisition 

Legacy Frontier Pipeline and Tankage Asset Transaction 
On November 9, 2011, HEP acquired from us certain tankage, loading rack and crude receiving assets located at our 
El Dorado and Cheyenne Refineries.  We received non-cash consideration consisting of promissory notes with an 
aggregate principal amount of $150 million and 3.8 million HEP common units.  

2010 Acquisition 

Tulsa East / Lovington Storage Asset Transaction 
On March 31, 2010, HEP acquired from us certain storage assets for $93 million, consisting of hydrocarbon storage 
tanks  having  approximately  2  million  barrels  of  storage  capacity,  a  rail  loading  rack  and  a  truck  unloading  rack 
located at our Tulsa East facility and an asphalt loading rack facility located at our Navajo Refinery facility located 
in Lovington, New Mexico. 

2009 Acquisitions 

Sinclair Logistics and Storage Assets Transaction 
On December 1, 2009, HEP acquired from Sinclair storage tanks having approximately 1.4 million barrels of storage 
capacity and loading racks at what is now our Tulsa East facility for $79.2 million.   

Roadrunner / Beeson Pipelines Transaction 
Also on December 1, 2009, HEP acquired our two newly constructed pipelines for $46.5 million, consisting of a 65-
mile, 16-inch crude oil pipeline (the “Roadrunner Pipeline”) that connects our Navajo Refinery Lovington facility  
to a terminus of Centurion Pipeline L.P.’s pipeline extending between west Texas and Cushing, Oklahoma and a 37-
mile, 8-inch crude oil pipeline that connects HEP’s New Mexico crude oil gathering system to our Navajo Refinery 
Lovington facility (the “Beeson Pipeline”). 

Tulsa West Loading Racks Transaction 
On August 1, 2009, HEP acquired from us, certain truck and rail loading/unloading facilities located at our Tulsa 
West facility for $17.5 million.  The racks load refined products and lube oils produced at the Tulsa West facility 
onto rail cars and/or tanker trucks.   

Lovington-Artesia Pipeline Transaction 
On June 1, 2009, HEP acquired our newly constructed, 16-inch intermediate pipeline for $34.2 million that runs 65 
miles  from  our  Navajo  Refinery’s  crude  oil  distillation  and  vacuum  facilities  in  Lovington,  New  Mexico  to  our 
petroleum refinery located in Artesia, New Mexico.   

-18-

 
 
 
 
 
 
 
 
 
 
 
 
 
 
SLC Pipeline Joint Venture Interest 
On March 1, 2009, HEP acquired a 25% joint venture interest in the SLC Pipeline, a new 95-mile intrastate pipeline 
system jointly owned with Plains.  HEP’s capitalized joint venture contribution was $25.5 million.  

Rio Grande Pipeline Sale 

On December 1, 2009, HEP sold its 70% interest in Rio Grande Pipeline Company (“Rio Grande”) to a subsidiary of 
Enterprise Products Partners LP for $35 million. Results of operations of Rio Grande are presented in discontinued 
operations. 

Transportation Agreements 

Agreements with HEP 
HEP  serves  our  refineries  under  long-term  pipeline  and  terminal,  tankage  and  throughput  agreements  expiring  in 
2019 through 2026.  Under these agreements, we pay HEP fees to transport, store and throughput volumes of refined 
product  and  crude oil  on  HEP’s  pipeline  and  terminal,  tankage  and  loading  rack  facilities  that  result  in  minimum 
annual  payments  to  HEP.    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,  2011,  these  agreements  result  in  minimum 
annualized payments to HEP of $192 million. 

We  reconsolidated  HEP  effective  March  1,  2008.    Following  our  reconsolidation,  our  transactions  with  HEP 
including  fees  that  we  pay  under  our  HEP  transportation  agreements  are  eliminated  and  have  no  impact  on  our 
consolidated financial statements since HEP is a consolidated VIE.  

Agreement with Alon 
HEP has a 15-year pipelines and terminals agreement with Alon expiring in 2020, under which Alon has agreed to 
transport  on  HEP’s  pipelines  and  throughput  through  its  terminals,  volumes  of  refined  products  that  results  in  a 
minimum level of annual revenue.  The agreed upon tariff rates are increased or decreased annually at a rate equal to 
the  percentage  change  in  PPI,  but  will  not  decrease  below  the  initial  tariff  rate.    Also,  HEP  has  a  capacity  lease 
agreement with Alon under which Alon leases space on HEP’s Orla to El Paso pipeline for the shipment of up to 
15,000 barrels of refined product per day.  The terms under this agreement expire in 2018 through 2022.  

As of December 31, 2011, HEP’s assets include: 

Pipelines 
• 

approximately 820 miles of refined product pipelines, including 340 miles of leased pipelines, that transport 
gasoline, diesel and jet fuel principally from our Navajo Refinery in New Mexico to our customers in the 
metropolitan and rural areas of Texas, New Mexico, Arizona, Colorado, Utah and northern Mexico; 
approximately 510 miles of refined product pipelines that transport refined products from Alon’s Big Spring 
refinery in Texas to its customers in Texas and Oklahoma;

ADDITIONAL OPERATIONS AND OTHER INFORMATION 

Corporate Offices 
We lease approximately 46,000 square feet for our principal corporate offices in Dallas, Texas.  The lease for our 
principal  corporate  offices  expires  in  2021.    Functions  performed  in  the  Dallas  office  include  overall  corporate 
management, refinery and HEP management, planning and strategy, corporate finance, crude acquisition, logistics, 
contract  administration,  marketing,  investor  relations,  governmental  affairs,  accounting,  tax,  treasury,  information 
technology, legal and human resources support functions.  

Employees and Labor Relations 
As of December 31, 2011, we had 2,382 employees, of which 797 are currently covered by collective bargaining 
agreements  having  various  expiration  dates  between  2012  and  2016.    We  consider  our  employee  relations  to  be 
good.   

Regulation 
Refinery  and pipeline operations  are  subject  to  numerous  federal,  state  and  local  laws  regulating  the  discharge of 
substances  into  the  environment  or  otherwise  relating  to  the  protection  of  the  environment.    Permits  are  required 
under these laws for the operation of our refineries, pipelines and related facilities, and these permits are subject to 
revocation, modification and renewal.  Over the years, there have been and continue to be ongoing communications, 
including  notices  of  violations,  and  discussions  about  environmental  matters  between  us  and  federal  and  state 
authorities,  some  of  which  have  resulted  or  will  result  in  changes  to  operating  procedures  and  in  capital 
expenditures.    Compliance  with  applicable  environmental  laws,  regulations  and  permits  will  continue  to  have  an 
impact  on  our  operations,  the  results  of  operations,  and  our  capital  requirements.    We  believe  that  our  current 
operations  are  in  substantial  compliance  with  applicable  federal,  state,  and  local  environmental  laws,  regulations, 
and permits. 

Our operations and many of the products we manufacture are subject to certain requirements of the Federal Clean 
Air  Act  (“CAA”)  as  well  as  related  state  and  local  laws  and  regulations.    Certain  CAA  regulatory  programs 
applicable to our refineries require capital expenditures for the installation of certain air pollution control devices.  

-20-

 
 
 
 
 
 
 
 
Subsequent rulemaking authorized by the CAA or similar laws, or new agency interpretations of existing laws and 
regulations, may necessitate additional expenditures in future years. 

Under the CAA, the Environmental Protection Agency (“EPA”) has the authority to modify the formulation of the 
refined transportation fuel products we manufacture in order to limit the emissions associated with their final use.  In 
June 2004, the EPA issued new regulations limiting emissions from diesel fuel powered engines used in non-road 
activities such as mining, construction, agriculture, rail transport, and marine operations and simultaneously limiting 
the sulfur content of diesel fuel used in these engines to facilitate compliance with the new emission standards.  As 
of December 31, 2011, all of our refineries produce non-road and highway diesel that meets the ultimate 15 ppm 
sulfur standard.   

Our  refineries  are  subject  to  another  EPA  regulation  limiting  the  annual  average  sulfur  content  in  gasoline  to  30 
ppm.    Currently,  our  refineries  either  meet  this  standard  and  balance  annual  average  requirements  by  purchasing 
from third parties or using internally generated sulfur credits.   

Also,  we  are  subject  to  the  EPA’s  new  Control  of  Hazardous  Air  Pollutants  from  Mobile  Sources  (“MSAT2”) 
regulations on gasoline that impose reductions in the benzene content of our produced gasoline.  Our Tulsa, Navajo 
and  Woods  Cross  Refineries  currently  purchase  benzene  credits  to  meet  these  requirements.    Our  remaining 
refineries become subject to the regulation in 2013.  Our planned capital projects will reduce the amount of benzene 
credits  that  we  need  to  purchase.    If  economically  justified,  we  could  implement  additional  benzene  reduction 
projects to eliminate the need to purchase any benzene credits.  

The Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007 prescribe certain percentages 
of renewable fuels (e.g., ethanol and biofuels) that, where required, must be blended into our produced gasoline and 
diesel.    These  new  requirements,  other  requirements  of  the  CAA,  and  other  presently  existing  or  future 
environmental  regulations  may,  where  required,  cause  us  to  make  substantial  capital  expenditures  and  purchase 
credits at significant cost to enable our refineries to produce products that meet applicable requirements. 

Further  regulatory  requirements  have  emerged  from  concerns  over  the  potential  climate  impacts  of  certain 
"greenhouse  gases"  such  as  carbon  dioxide  and  methane.    In  response  to  a  statutory  directive,  the  EPA  has 
promulgated rules requiring the reporting of greenhouse gas emissions.  In 2010, the EPA promulgated regulations 
applying construction and operating permit requirements under the CAA’s Prevention of Significant Deterioration 
and Title V programs to sources with potential greenhouse gas emissions above certain threshold levels. The EPA 
has  also  announced  its  intention  to  issue  a  New  Source  Performance  Standard  directly  regulating  greenhouse  gas 
emissions  from  refineries.    Proposals  both  expanding  and  limiting  the  EPA's  authority  in  this  area  continue  to  be 
considered in Congress, and litigation challenging the EPA’s authority over greenhouse gas emissions is currently 
pending in federal court.  

Our  operations  are  also  subject  to  the  Federal  Clean  Water  Act  (“CWA”),  the  Federal  Safe  Drinking  Water  Act 
(“SDWA”) and comparable state and local requirements.  The CWA, the SDWA and analogous laws prohibit any 
discharge  into  surface  waters,  ground  waters,  injection  wells  and  publicly-owned  treatment  works  except  in 
conformance  with  permits,  such  as  pre-treatment  permits  and  National  Pollutant  Discharge  Elimination  System 
(“NPDES”) permits, issued by federal, state and local governmental agencies.  NPDES permits and analogous water 
discharge permits are valid for a maximum of five years and must be renewed. 

We generate wastes that may be subject to the Resource Conservation and Recovery Act (“RCRA”) and comparable 
state and local requirements.  The EPA and various state agencies have limited the approved methods of disposal for 
certain hazardous and non-hazardous wastes. 

The  Comprehensive  Environmental  Response,  Compensation  and  Liability  Act  (“CERCLA”),  also  known  as 
“Superfund,” imposes liability, without regard to fault or the legality of the original conduct, on certain classes of 
persons, including the current and past owner or operator of the disposal site or sites from which there is a release of 
a  “hazardous  substance,”  as  well  as  persons  that  disposed  of  or  arranged  for  the  disposal  or  treatment  of  the 
hazardous substances at the site or sites.  Under CERCLA, such persons may be subject to joint and several liability 
for such costs as the cost of cleaning up the hazardous substances that have been released into the environment and 
for  damages  to  natural  resources.    In  the  course  of  our  historical  operations,  as  well  as  in  our  current  normal 

-21-

 
 
 
 
 
 
 
 
 
operations, we have generated waste, some of which falls within the statutory definition of a “hazardous substance” 
and  some  of  which  may  have  been  disposed  of  at  sites  that  may  be  subject  to  cleanup  and  cost  recovery  actions 
under  CERCLA  by  a  government  entity  or  other  third  party.    Similarly,  locations  now  owned  or  operated  by  us, 
where  third  parties  have disposed  such  hazardous  substances  in  the past,  may  also  be subject  to  cleanup  and  cost 
recovery actions under CERCLA.  Under CERCLA, liable parties may seek contribution from other liable parties to 
share  in  the  costs  of  cleanup.    Some  states  have  enacted  laws  similar  to  CERCLA  which  impose  similar 
responsibilities and liabilities on responsible parties.  It is also not uncommon for neighboring landowners and other 
third parties to file claims under state law for personal injury and property damage allegedly caused by hazardous 
substances or other pollutants released into the environment.   

As is the case with all companies engaged in industries similar to ours, we face potential exposure to future claims 
and  lawsuits  involving  environmental  matters.    These  matters  include  soil  and  water  contamination,  air  pollution, 
personal  injury  and  property  damage  allegedly  caused  by  substances  which  we  manufactured,  handled,  used, 
released or disposed of. 

We  currently  have  environmental  remediation  projects  that  relate  to  recovery,  treatment  and  monitoring  activities 
resulting from past releases of refined product and crude oil into the environment.  As of December 31, 2011, we 
had an accrual of $42.2 million related to such environmental liabilities. 

We  are  and  have  been  the  subject  of  various  state,  federal  and  private  proceedings  and  inquiries  relating  to 
compliance  with  environmental  regulations  and  conditions,  including  those  discussed  above.    Compliance  with 
current and future environmental regulations is expected to require additional expenditures, including expenditures 
for investigation and remediation, which may be significant, at our refineries and at pipeline transportation facilities.  
To the extent that future expenditures for these purposes are material and can be reasonably determined, these costs 
are disclosed and accrued, if applicable. 

Our  operations  are  also  subject  to  various  laws  and  regulations  relating  to  occupational  health  and  safety.    We 
maintain  safety,  training  and  maintenance  programs  as  part  of  our  ongoing  efforts  to  ensure  compliance  with 
applicable  laws  and  regulations.    Compliance  with  applicable  health  and  safety  laws  and regulations  has  required 
and continues to require substantial expenditures. 

Health and environmental legislation and regulations change frequently.  We cannot predict what additional health 
and  environmental  legislation  or  regulations  will  be  enacted  or  become  effective  in  the  future  or  how  existing  or 
future laws or regulations will be administered or interpreted with respect to our operations.  Compliance with more 
stringent laws or regulations or adverse changes in the interpretation of existing laws or regulations by government 
agencies could have an adverse effect on 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. 

Insurance 
Our operations are subject to normal hazards of operations, including fire, explosion and weather-related perils.  We 
maintain various insurance coverages, including business interruption insurance, subject to certain deductibles.  We 
are  not  fully  insured  against  certain  risks  because  such  risks  are  not  fully  insurable,  coverage  is  unavailable,  or 
premium costs, in our judgment, do not justify such expenditures. 

We have a risk management oversight committee that is made up of members from our senior management.  This 
committee oversees our risk enterprise program, monitors our risk environment and provides direction for activities 
to mitigate identified risks that may adversely affect the achievement of our goals.

Item 1A.  Risk Factors 

Investing in us involves a degree of risk, including the risks described below. Our operating results have been, and 
will continue to be, affected by a wide variety of risk factors, many of which are beyond our control, that could have 
adverse effects on profitability during any particular period. You should carefully consider the following risk factors 
together  with  all  of  the  other  information  included  in  this  Annual  Report  on  Form  10-K,  including  the  financial 
statements and related notes, when deciding to invest in us. Additional risks and uncertainties not currently known to 
us or that we currently deem to be immaterial may also materially and adversely affect our business operations. If 
any of the following risks were to actually occur, our business, financial condition or results of operations could be 
materially and adversely affected.  

The  prices  of  crude  oil  and  refined  products  materially  affect  our  profitability,  and  are  dependent  upon  many 
factors  that  are  beyond  our  control,  including  general  market  demand  and  economic  conditions,  seasonal  and 
weather-related factors and governmental regulations and policies.  

Among these factors is the demand for crude oil and refined products, which is largely driven by the conditions of 
local and worldwide economies as well as by weather patterns and the taxation of these products relative to other 
energy  sources.  Governmental  regulations  and  policies,  particularly  in  the  areas  of  taxation,  energy  and  the 
environment,  also  have  a  significant  impact  on  our  activities.  Operating  results  can  be  affected  by  these  industry 
factors,  product  and  crude  pipeline  capacities,  changes  in  transportation  costs,  accidents  or  interruptions  in 
transportation, competition in the particular geographic areas that we serve, and factors that are specific to us, such 
as the success of particular marketing programs and the efficiency of our refinery operations. The demand for crude 
oil and refined products can also be reduced due to a local or national recession or other adverse economic condition 
that results in lower spending by businesses and consumers on gasoline and diesel fuel, higher gasoline prices due to 
higher  crude  oil  prices,  a  shift  by  consumers  to  more  fuel-efficient  vehicles  or  alternative  fuel  vehicles  (such  as 
ethanol  or  wider  adoption  of  gas/electric  hybrid  vehicles),  or  an  increase  in  vehicle  fuel  economy,  whether  as  a 
result of technological advances by manufacturers, legislation mandating or encouraging higher fuel economy or the 
use of alternative fuel.  

We  do  not  produce  crude  oil  and  must  purchase  all  our  crude  oil,  the  price  of  which  fluctuates  based  upon 
worldwide and local market conditions.  Our profitability depends largely on the spread between market prices for 
refined petroleum products and crude oil prices. This margin is continually changing and may fluctuate significantly 
from  time  to  time.  Crude  oil  and  refined  products  are  commodities  whose  price  levels  are  determined  by  market 
forces beyond our control. 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. 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  flows.    Also,  crude  oil  supply  contracts  are 
generally  short-term  contracts  with  market-responsive  pricing  provisions.    We  purchase  our  refinery  feedstocks 
weeks  before  manufacturing  and  selling  the  refined  products.    Price  level  changes  during  the  period  between 
purchasing feedstocks and selling the manufactured refined products from these feedstocks could have a significant 
effect on our financial results.   

We  may  not  be  able  to  successfully  execute  our  business  strategies  to  grow  our  business.     Further,  if  we  are 
unable  to  complete  capital  projects  at  their  expected  costs  or  in  a  timely  manner,  or  if  the  market  conditions 
assumed in our project economics deteriorate, our financial condition, results of operations, or cash flows could 
be materially and adversely affected.   

One  of  the  ways  we  may  grow  our  business  is  through  the  construction  of  new  refinery  processing  units  (or  the 
purchase  and  refurbishment  of  used  units  from  another  refinery)  and  the  expansion  of  existing  ones.  Projects  are 
generally initiated to increase the yields of higher-value products, increase the amount of lower cost crude oils that 

-23-

 
 
 
 
 
 
 
can  be  processed,  increase  refinery  production  capacity,  meet  new  governmental  requirements,  or  maintain  the 
operations  of  our  existing  assets.    Additionally,  our  growth  strategy  includes  projects  that  permit  access  to  new 
and/or  more  profitable  markets  such  as  our  UNEV  Pipeline  joint  venture,  a  12-inch  refined  products  pipeline 
running  from  Salt  Lake  City,  Utah  to  Las  Vegas,  Nevada  in  which  our  subsidiary  owns  a  75%  interest.    The 
construction process involves numerous regulatory, environmental, political, and legal uncertainties, most of which 
are not fully within our control, including:  

 •  denial or delay in issuing requisite regulatory approvals and/or permits; 
 •  compliance with or liability under environmental regulations;  
 •  unplanned increases in the cost of construction materials or labor; 
 •  disruptions in transportation of modular components and/or construction materials;  
 •  severe  adverse  weather  conditions,  natural  disasters,  or  other  events  (such  as  equipment  malfunctions 

explosions, fires, spills) affecting our facilities, or those of vendors and suppliers; 

 •  shortages of sufficiently skilled labor, or labor disagreements resulting in unplanned work stoppages; 
 •  market-related increases in a project’s debt or equity financing costs; and/or 
 •  nonperformance  or  force  majeure  by,  or  disputes  with,  vendors,  suppliers,  contractors,  or  sub-contractors 

involved with a project. 

If we are unable to complete capital projects at their expected costs or in a timely manner our financial condition, 
results of operations, or cash flows could be materially and adversely affected.  Delays in making required changes 
or  upgrades  to  our  facilities  could  subject  us  to  fines  or  penalties  as  well  as  affect  our  ability  to  supply  certain 
products  we  make.  In  addition,  our  revenues  may  not  increase  immediately  upon  the  expenditure  of  funds  on  a 
particular  project.  For  instance,  if  we  build  a  new  refinery  processing  unit,  the  construction  will  occur  over  an 
extended  period  of  time  and  we  will  not  receive  any  material  increases  in  revenues  until  after  completion  of  the 
project. Moreover, we may construct facilities to capture anticipated future growth in demand for refined products in 
a  region  in  which  such  growth  does  not  materialize.  As  a  result,  new  capital  investments  may  not  achieve  our 
expected investment return, which could adversely affect our results of operations and financial condition.  

Our forecasted internal rates of return are also based upon our projections of future market fundamentals which are 
not within our control, including changes in general economic conditions, available alternative supply and customer 
demand. 

In  addition,  a  component  of  our  growth  strategy  is  to  selectively  acquire  complementary  assets  for  our  refining 
operations  in  order  to  increase  earnings  and  cash  flow.  Our  ability  to  do  so  will  be  dependent  upon  a  number  of 
factors,  including  our  ability  to  identify  attractive  acquisition  candidates,  consummate  acquisitions  on  favorable 
terms,  successfully  integrate  acquired  assets  and  obtain  financing  to  fund  acquisitions  and  to  support  our  growth, 
and other factors beyond our control. Risks associated with acquisitions include those relating to:  

 •  diversion of management time and attention from our existing business;  
 •  challenges in managing the increased scope, geographic diversity and complexity of operations;  
 •  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 in achieving anticipated operational improvements;  
 •  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.  

We  may  not  be  successful  in  acquiring  additional  assets,  and  any  acquisitions  that  we  do  consummate  may  not 
produce the anticipated benefits or may have adverse effects on our business and operating results.  

-24-

 
  
 
 
 
 
 
 
Our  leverage  may  limit  our  ability  to  borrow  additional  funds,  comply  with  the  terms  of  our  indebtedness  or 
capitalize on business opportunities.      

As  of  December  31,  2011,  the  principal  amount  of  our  total  consolidated  outstanding  debt  was  $1,214.4  million, 
including $535 million of HEP debt.  

Our leverage could have important consequences. We require substantial cash flow to meet our payment obligations 
with respect to our indebtedness. Our ability to make scheduled payments, to refinance our obligations with respect 
to  our  indebtedness  or  our  ability  to  obtain  additional  financing  in  the  future  will  depend  on  our  financial  and 
operating performance, which, in turn, is subject to prevailing economic conditions and to financial, business and 
other  factors.  We  believe  that  we  will  have  sufficient  cash  flow  from  operations,  available  cash  on  hand,  and 
available borrowings under our Credit Agreement to service our indebtedness. However, a significant downturn in 
our business or other development adversely affecting our cash flow could materially impair our ability to service 
our indebtedness. If our cash flow and capital resources are insufficient to fund our debt service obligations, we may 
be  forced  to  refinance  all  or  a  portion  of  our  debt  or  sell  assets.  We  cannot  assure  you  that  we  would  be  able  to 
refinance our existing indebtedness at maturity or otherwise or sell assets on terms that are commercially reasonable. 

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  most  recently,  low  consumer  confidence,  continued  high  unemployment, 
geoeconomic and geopolitical issues, weak economic conditions and uncertainty in the financial services sector. In 
addition,  the  fixed-income  markets  have  experienced  periods  of  extreme  volatility,  which  negatively  impacted 
market  liquidity  conditions.  As  a  result,  the  cost  of  raising  money  in  the  debt  and  equity  capital  markets  has 
increased  substantially  at  times  while  the  availability  of  funds  from  these  markets  diminished  significantly.  In 
particular,  as  a  result  of  concerns  about  the  stability  of  financial  markets  generally  and  the  solvency  of  lending 
counterparties specifically, the cost of obtaining money from the credit markets may increase as many lenders and 
institutional  investors  increase  interest  rates,  enact  tighter  lending  standards,  refuse  to  refinance  existing  debt  on 
similar  terms  or  at  all  and  reduce,  or  in  some  cases  cease,  to  provide  funding  to  borrowers.  In  addition,  lending 
counterparties  under  existing  revolving  credit  facilities  and  other  debt  instruments  may  be  unwilling  or  unable  to 
meet their funding obligations. 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. Moreover, without adequate funding, we may be unable to 
execute  our  growth  strategy,  complete  future  acquisitions  or  announced  and  future  pipeline  construction  projects, 
take  advantage  of  other  business  opportunities  or  respond  to  competitive  pressures,  any  of  which  could  have  a 
material adverse effect on our revenues and results of operations. 

We may incur significant costs to comply with new or changing environmental, energy, health and safety laws 
and regulations, and face potential exposure for environmental matters.  

Refinery  and  pipeline  operations  are  subject  to  federal,  state  and  local  laws  regulating,  among  other  things,  the 
generation,  storage,  handling,  use  and  transportation  of  petroleum  and  hazardous  substances,  the  emission  and 
discharge of materials into the environment, waste management, and characteristics and composition of gasoline and 
diesel fuels, and other matters otherwise relating to the protection of the environment. Permits are required under 
these  laws  for  the  operation  of  our  refineries,  pipelines  and  related  operations,  and  these  permits  are  subject  to 
revocation,  modification  and  renewal  or  may  require  operational  changes,  which  may  involve  significant  costs.  
Furthermore,  a  violation  of  permit  conditions  or  other  legal  or  regulatory  requirements  could  result  in  substantial 
fines,  criminal  sanctions,  permit  revocations,  injunctions,  and/or  refinery  shutdowns.    In  addition,  major 
modifications of our operations due to changes in the law could require changes to our existing permits or expensive 
upgrades to our existing pollution control equipment, which could have a material adverse effect on our business, 
financial  condition,  or  results  of  operations.  Over  the  years,  there  have  been  and  continue  to  be  ongoing 
communications,  including  notices  of  violations,  and  discussions  about  environmental  matters  between  us  and 
federal and state authorities, some of which have resulted or will result in changes to operating procedures and in 
capital expenditures. Compliance with applicable environmental laws, regulations and permits will continue to have 
an impact on our operations, results of operations and capital requirements.  

-25-

 
 
 
 
 
 
 
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  soil  and  water  contamination,  air  pollution, 
personal  injury  and  property  damage  allegedly  caused  by  substances  which  we  manufactured,  handled,  used, 
released or disposed.  

We  are  and  have  been  the  subject  of  various  state,  federal  and  private  proceedings  relating  to  environmental 
regulations, conditions and inquiries. Current and future environmental regulations are expected to require additional 
expenditures, including expenditures for investigation and remediation, which may be significant, at our facilities. 
To the extent that future expenditures for these purposes are material and can be reasonably determined, these costs 
are disclosed and accrued.  

Our  operations  are  also  subject  to  various  laws  and  regulations  relating  to  occupational  health  and  safety.  We 
maintain  safety,  training  and  maintenance  programs  as  part  of  our  ongoing  efforts  to  ensure  compliance  with 
applicable laws and regulations. Compliance with applicable health and safety laws and regulations has required and 
continues to require substantial expenditures.  

We  cannot  predict  what  additional  health  and  environmental  legislation  or  regulations  will  be  enacted  or  become 
effective in the future or how existing or future laws or regulations will be administered or interpreted with respect 
to  our  operations.  However,  new  environmental  laws  and  regulations,  including  new  regulations  relating  to 
alternative  energy  sources  and  the  risk  of  global  climate  change,  new  interpretations  of  existing  laws  and 
regulations,  increased  governmental  enforcement  or  other  developments  could  require  us  to  make  additional 
unforeseen  expenditures.  The  EPA  has  begun  regulating  certain  emissions  of  greenhouse  gases,  or  “GHGs,” 
(including  carbon  dioxide,  methane  and  nitrous  oxides)  from  large  stationary  sources  like  refineries  under  the 
authority of the CAA, and it is possible that Congress could pass federal legislation that creates a comprehensive 
GHG  regulatory  program,  either  directly  or  indirectly,  such  as  via  a  federal  renewal  energy  standard.    Also,  new 
federal  or  state  legislation  or  regulatory  programs  that  restrict  emissions  of  GHGs  in  areas  where  we  conduct 
business could adversely affect our operations and demand for our products.   

The costs of environmental and safety regulations are already significant and compliance with more stringent laws 
or regulations or adverse changes in the interpretation of existing regulations by government agencies could have an 
adverse effect on the financial position and the results of our operations and could require substantial expenditures 
for the installation and operation of systems and equipment that we do not currently possess.  

From time to time, new federal energy policy legislation is enacted by the U.S. Congress. For example, in December 
2007,  the  U.S.  Congress  passed  the  Energy  Independence  and  Security  Act,  which,  among  other  provisions, 
mandates  annually  increasing  levels  for  the  use  of  renewable  fuels  such  as  ethanol,  commencing  in  2008  and 
escalating for 15 years, as well as increasing energy efficiency goals, including higher fuel economy standards for 
motor vehicles, among other steps. These statutory mandates may have the impact over time of offsetting projected 
increases in the demand for refined petroleum products in certain markets, particularly gasoline.  In the near term, 
the  new  renewable  fuel  standard  presents  ethanol  production  and  logistics  challenges  for  both  the  ethanol  and 
refining  industries  and  may  require  additional  capital  expenditures  or  expenses  by  us  to  accommodate  increased 
ethanol use.  Other legislative changes may similarly alter the expected demand and supply projections for refined 
petroleum products in ways that cannot be predicted. 

For  additional  information  on  regulations  and  related  liabilities  or  potential  liabilities  affecting  our  business,  see 
“Regulation” under Items 1 and 2, “Business and Properties,” and Item 3, “Legal Proceedings.”  

The  adoption  of  climate  change  legislation  by  Congress  could  result  in  increased  operating  costs  and  reduced 
demand for the refined products we produce. 

 In  December  2009,  the  EPA  determined  that  emissions  of  carbon  dioxide,  methane  and  other  GHGs  present  an 
endangerment  to  public  health  and  the  environment  because  emissions  of  such  gases  are,  according  to  the  EPA, 
contributing to warming of the earth’s atmosphere and other climatic changes.  Based on these findings, the EPA has 
begun adopting and implementing regulations to restrict emissions of GHGs under existing provisions of the federal 
CAA.  The EPA also adopted two sets of rules regulating GHG emissions under the CAA, one of which requires a 

-26-

 
 
 
 
 
 
 
 
 
 
reduction  in  emissions  of  GHGs  from  motor  vehicles  and  the  other  of  which  regulates  emissions  of  GHGs  from 
certain large stationary sources.  The EPA’s rules relating to emissions of GHGs from large stationary sources of 
emissions are currently subject to a number of legal challenges, but the federal courts have thus far declined to issue 
any injunctions to prevent the EPA from implementing or requiring state environmental agencies to implement the 
rules.    The  EPA  has  also  adopted  rules  requiring  the  reporting  of  GHG  emissions  from  specified  large  GHG 
emission sources in the United States, including petroleum refineries, on an annual basis. 

In addition, the United States Congress has from time to time considered adopting legislation to reduce emissions of 
GHGs and almost one-half of the states have already taken legal measures to reduce emissions of GHGs primarily 
through  the  planned  development  of  GHG  emission  inventories  and/or  regional  GHG  cap  and  trade  programs.  
These cap and trade programs generally work by requiring major sources of emissions, such as electric power plants, 
or major producers of fuels, such as refineries and gas processing plants, to acquire and on an annual basis surrender 
emission allowances. The number of allowances available for purchase is reduced over time in an effort to achieve 
the overall GHG emission reduction goal. 

The adoption of legislation or regulatory programs to reduce emissions of GHGs could require us to incur increased 
operating costs, such as costs to purchase and operate emissions control systems, to acquire emissions allowances or 
comply  with  new  regulatory  or  reporting  requirements.  Any  such  legislation  or  regulatory  programs  could  also 
increase  the  cost  of  consuming,  and  thereby  reduce  demand  for,  the  refined  products  that  we  produce.  
Consequently, legislation and regulatory programs to reduce emissions of GHGs could have an adverse effect on our 
business, financial condition and results of operations.  

In addition, some scientists have concluded that increasing concentrations of GHGs in the Earth’s atmosphere may 
produce climate changes that have significant physical effects, such as increased frequency and severity of storms, 
droughts, floods and other climatic events. If any such events were to occur, they could have an adverse effect on 
our financial condition and results of operations.  

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

Information technology system failures, network disruptions (whether intentional by a third party or due to natural 
disaster), breaches of network or data security, or disruption or failure of the network system used to monitor and 
control pipeline operations could disrupt our operations by impeding our processing of transactions, our ability to 
protect customer or company information and our financial reporting. Our computer systems, including our back-up 
systems, could be damaged or interrupted by power outages, computer and telecommunications failures, computer 
viruses,  internal  or  external security  breaches,  events  such  as  fires,  earthquakes, floods,  tornadoes and  hurricanes, 
and/or  errors  by  our  employees.  Although  we  have  taken  steps  to  address  these  concerns  by  implementing 
sophisticated network security and internal control measures, there can be no assurance that a system failure or data 
security breach will not have a material adverse effect on our financial condition and results of operations. 

To  successfully  operate  our  petroleum  refining  facilities,  we  are  required  to  expend  significant  amounts  for 
capital outlays and operating expenditures.  

The  refining business  is  characterized  by high fixed  costs  resulting  from  the  significant  capital  outlays  associated 
with refineries, terminals, pipelines and related facilities. We are dependent on the production and sale of quantities 
of refined products at refined product margins sufficient to cover operating costs, including any increases in costs 
resulting from future inflationary pressures or market conditions and increases in costs of fuel and power necessary 
in  operating  our  facilities.  Furthermore,  future  regulatory  requirements  or  competitive  pressures  could  result  in 
additional  capital  expenditures,  which  may  not  produce  a  return  on  investment.  Such  capital  expenditures  may 
require significant financial resources that may be contingent on our access to capital markets and commercial bank 
loans. Additionally, other matters, such as regulatory requirements or legal actions, may restrict our access to funds 
for capital expenditures.  

Our refineries consist of many processing units, a number of which have been in operation for many years.  One or 
more  of  the  units  may  require  unscheduled  downtime  for  unanticipated  maintenance  or  repairs  that  are  more 
frequent than our scheduled turnaround for such units.  Scheduled and unscheduled maintenance could reduce our 
revenues during the period of time that the units are not operating.  We have taken significant measures to expand 

-27-

 
  
 
 
 
 
 
 
 
and upgrade units in our refineries by installing new equipment and redesigning older equipment to improve refinery 
capacity.    The  installation  and  redesign  of  key  equipment  at  our  refineries  involves  significant  uncertainties, 
including  the  following:  our  upgraded  equipment  may  not  perform  at  expected  throughput  levels;  the  yield  and 
product quality of new equipment may differ from design and/or specifications and redesign or modification 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 results of operations and financial condition. 

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

Our  operations  are  subject  to  operational  hazards  and  unforeseen  interruptions  such  as  natural  disasters,  adverse 
weather,  accidents,  fires,  explosions,  hazardous  materials  releases,  power  failures,  mechanical  failures  and  other 
events beyond our control. These events might result in a loss of equipment or life or destruction of property, injury, 
or extensive property damage, as well as a curtailment or an interruption in our operations and may affect our ability 
to meet marketing commitments. Furthermore, we may not be able to maintain or obtain insurance of the type and 
amount we desire at reasonable rates. As a result of market conditions, premiums and deductibles for certain of our 
insurance policies could increase. In some instances, certain insurance could become unavailable or available only 
for reduced amounts of coverage. If we were to incur a significant liability for which we were not fully insured, it 
could have a material adverse effect on our financial position.  If any refinery were to experience an interruption in 
operations, earnings from the refinery could be materially adversely affected (to the extent not recoverable through 
insurance) because of lost production and repair costs.    

We  maintain  significant  insurance  coverage,  but  it  does  not  cover  all  potential  losses,  costs  or  liabilities,  and  our 
business interruption insurance coverage generally does not apply unless a business interruption exceeds 45 days. 
We could suffer losses for uninsurable or uninsured risks or in amounts in excess of our existing insurance coverage. 
Our ability to obtain and maintain adequate insurance may be affected by conditions in the insurance market over 
which we have no control. The occurrence of an event that is not fully covered by insurance could have a material 
adverse effect on our business, financial condition and results of operations.    

The  energy  industry  is  highly  capital  intensive,  and  the  entire  or  partial  loss  of  individual  facilities  can  result  in 
significant costs to both industry companies, such as us, and their insurance carriers. In recent years, several large 
energy industry claims have resulted in significant increases in the level of premium costs and deductible periods for 
participants  in  the  energy  industry.  As  a  result  of  large  energy  industry  claims,  insurance  companies  that  have 
historically  participated  in  underwriting  energy-related  facilities  may  discontinue  that  practice  or  demand 
significantly higher premiums or deductible periods to cover these facilities. If significant changes in the number or 
financial solvency of insurance underwriters for the energy industry occur, or if other adverse conditions over which 
we have no control prevail in the insurance market, we may be unable to obtain and maintain adequate insurance at 
reasonable  cost.    In  addition,  we  cannot  assure  you  that  our  insurers  will  renew  our  insurance  coverage  on 
acceptable terms, if at all, or that we will be able to arrange for adequate alternative coverage in the event of non-
renewal.  Further, our underwriters could have credit issues that affect their ability to pay claims.  The unavailability 
of full insurance coverage to cover events in which we suffer significant losses could have a material adverse effect 
on our business, financial condition and results of operations. 

Insufficient  ethanol,  biodiesel,  and  other  advanced  biofuel  supplies,  or  disruption  in  supply,  may  disrupt  our 
ability  to  meet  RFS2  regulations mandated  by  the  federal government or  required  in  the  fuels  markets  that  we 
serve. 

If  we  are  unable  to  obtain  or  maintain  sufficient  quantities  of  ethanol  for  our  blending  needs,  our  sale  of  ethanol 
gasoline (required in several of our markets) could be interrupted or suspended which could result in lower profits. 

-28-

 
 
 
 
 
 
 
  
Likewise, if we are unable to purchase renewable identification numbers (“RINs”), or if our supply of RINs is such 
that  we  have  to  pay a  significantly  higher  price  for  RINs to  meet  our  mandated  blending  volumes  of  biofuels  per 
the RFS2 regulation, our profits would be significantly lower. If we are unable to pass the costs of compliance with 
RFS2 on to our customers, our profits would be significantly lower.   

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

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

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

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

Portions of our operations in the areas we operate 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. 

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.   

We may be unsuccessful in integrating the operations of the assets we have recently acquired or of any future 
acquisitions  with  our  operations,  and  in  realizing  all  or  any  part  of  the  anticipated  benefits  of  any  such 
acquisitions.  

From time to time, we evaluate and acquire assets and businesses that we believe complement our existing assets 
and businesses.  For example, we face certain challenges as we continue to integrate the operations of Frontier Oil 
Corporation, with whom we merged in 2011, into our business. Acquisitions may require substantial capital or the 
incurrence of substantial indebtedness.  Our capitalization and results of operations may change significantly as a 
result  of  the  acquisitions  we  recently  completed  or  as  a  result  of  future  acquisitions.  Acquisitions  and  business 
expansions  involve  numerous  risks,  including  difficulties  in  the  assimilation  of  the  assets  and  operations  of  the 
acquired  businesses,  inefficiencies  and  difficulties  that  arise  because  of  unfamiliarity  with  new  assets  and  the 
businesses associated with them and new geographic areas and the diversion of management’s attention from other 
business  concerns.  Further,  unexpected  costs  and  challenges  may  arise  whenever  businesses  with  different 
operations or management are combined, and we may experience unanticipated delays in realizing the benefits of an 
acquisition,  including  the  merger  in  2011.  Also,  following  an  acquisition,  we  may  discover  previously  unknown 
liabilities  associated  with  the  acquired  business  or  assets  for  which  we  have  no  recourse  under  applicable 
indemnification provisions. 

The new and revamped equipment in our facilities may not perform according to expectations which may cause 
unexpected maintenance and downtime and could have a negative effect on our future results of operations and 
financial condition. 

-29-

 
 
 
 
 
 
 
 
 
 
 
From time to time, we have major capital investment and various environmental compliance related projects at our 
refineries.    The  installation of new  equipment  and  the  revamp  of key  existing  equipment  involve significant risks 
and uncertainties, including the following: 

•  Equipment may not perform at expected throughput levels; 
•  Actual yields or product quality may differ from design; 
•  Actual operating costs may be higher than expected; 
•  Equipment may need to be redesigned, revamped, or replaced for the new units to perform as expected. 

A  material  decrease  in  the  supply  of  crude  oil  available  to  our  refineries  could  significantly  reduce  our 
production levels.  

To maintain or increase production levels at our refineries, we must continually contract for crude oil supplies from 
third  parties.  A  material  decrease  in  crude  oil  production  from  the  fields  that  supply  our  refineries,  as  a  result  of 
depressed  commodity  prices,  lack  of  drilling  activity,  natural  production  declines  or  otherwise,  could  result  in  a 
decline in the volume of crude oil available to our refineries. In addition, any prolonged disruption of a significant 
pipeline  that  is  used  in  supplying  crude  oil  to  our  refineries  or  the  potential  operation  of  a  new,  converted  or 
expanded crude oil pipeline that transports crude oil to other markets could result in a decline in the volume of crude 
oil  available  to  our  refineries.  Such  an  event  could  result  in  an  overall  decline  in  volumes  of  refined  products 
processed at our refineries and therefore a corresponding reduction in our cash flow. In addition, the future growth 
of our operations will depend in part upon whether we can contract for additional supplies of crude oil at a greater 
rate than the rate of natural decline in our currently connected supplies. If we are unable to secure additional crude 
oil  supplies  of  sufficient  quality  or  crude  pipeline  expansion  to  our  refineries,  we  will  be  unable  to  take  full 
advantage of current and future expansion of our refineries’ production capacities.  

The  disruption  or  proration  of  the  refined  product  distribution  systems  we  utilize  could  negatively  impact  our 
profitability. 

We utilize various common carrier or other third party pipeline systems to deliver our products to market.  The key 
systems utilized by Cheyenne, El Dorado, Navajo, Woods Cross, and Tulsa are Rocky Mountain, NuStar Energy, 
SFPP and Plains, Chevron, and Magellan, respectively.  All five refineries also utilize systems owned by HEP.  If 
these key pipelines or their associated tanks and terminals become inoperative or decrease the capacity available to 
us,  we  may  not  be  able  to  sell  our  product,  or  we  may  be  required  to  hold  our  product  in  inventory  or  supply 
products to our customers through an alternative pipeline or by rail or additional tanker trucks from the refinery, all 
of which could increase our costs and result in a decline in profitability. 

The proposed reversal of the Seaway Pipeline is expected to increase demand for crude oil from the Northwestern 
United States and Canada, which we expect to affect price advantages that have been in our favor and which may 
adversely affect our profit margins. 

On November 16, 2011, Enbridge Inc. and Enterprise Products Partners L.P. announced that they had agreed with 
ConocoPhillips  to  acquire  the  Seaway  Crude  Pipeline  System.   The  670-mile  Seaway  Crude  Pipeline  System 
includes  the  500-mile,  30-inch  diameter  Freeport,  Texas  to  Cushing,  Oklahoma  long-haul  system.   This  pipeline 
currently  transports  crude  oil  to  the  Cushing  facility  from  the  U.S.  Gulf  Coast;  however,  Enbridge,  Inc.  and 
Enterprise Products Partners L.P. announced their intention to reverse the direction of crude oil flows on the Seaway 
pipeline such that it will transport crude from Cushing, Oklahoma to the U.S. Gulf Coast. 

Our  profit  margins  depend  primarily  on  the  spread  between  the  price  of  crude  oil  and  the  price  of  the  refined 
product.   We  were  generally  able  to  purchase  crude  oil  at  favorable  prices  due  to  a  bottleneck  of  crude  oil  at  the 
Cushing,  Oklahoma  transport  hub.   This  bottleneck  prevented  crude  from  the  Northwestern  United  States  and 
Canada  from  reaching  many  competing  refineries.   The  reversal  of  the  Seaway  Crude  Pipeline  is  expected  to 
alleviate  this  bottleneck,  and  therefore  could  eliminate  the  market  dynamic  that  allowed  us  to  enjoy  favorable 
pricing.  This may adversely affect our profit margins. 

-30-

 
 
 
 
 
 
 
 
 
 
 
The potential operation of new or expanded refined product transportation pipelines could impact the supply of 
refined products to our existing markets.   

The refined product transportation pipelines that also supply the markets supplied by the Navajo Refinery include 
Longhorn, Kinder Morgan, Plains, HEP, and NuStar Energy.  The Longhorn Pipeline is a common carrier pipeline 
that  supplies  the  El  Paso  market  with  refined  products  from  refineries  as  distant  as  the  Texas  Gulf  Coast.    The 
Longhorn  Pipeline  is  a  converted  crude  oil  pipeline  with  an  approximate  capacity  of  72,000  BPD  of  refined 
products.    Magellan  purchased  the  Longhorn  Pipeline  out  of  bankruptcy  in  2009.    Flying  J  formerly  owned  the 
Longhorn Pipeline prior to its bankruptcy in 2008.  In addition to supplying Arizona markets from El Paso, Kinder 
Morgan also supplies Arizona  markets from the West Coast.  The Plains pipeline currently supplies New Mexico 
markets from El Paso.  In addition, NuStar Energy LP and HEP own pipelines into the El Paso and New Mexico 
markets.   

The  refined  product  transportation  pipelines  that  also  supply  the  markets  supplied  by  the  Woods  Cross  Refinery 
include Chevron, Pioneer, and Yellowstone Pipelines.  The Chevron system transports products from Salt Lake City 
to Idaho and eastern Washington.  The Pioneer Pipeline transports products from Wyoming and Montana refineries 
into  Salt  Lake  City.    The  Yellowstone  Pipeline  transports  products  from  Montana  refineries  into  eastern 
Washington. 

The  refined  product  transportation  pipelines  that  also  supply  the  markets  supplied  by  the  Tulsa  and  El  Dorado 
Refineries include Magellan, Explorer, and Kaneb Pipelines.  The Explorer Pipeline transports refined products from 
Gulf Coast refineries to Tulsa where it interconnects with Magellan prior to proceeding to the Chicago area.  The 
Kaneb  Pipeline  transports  refined  products  from  northern  Texas,  Oklahoma,  and  Kansas  refineries  to  markets  in 
Kansas,  Nebraska,  Iowa,  North  Dakota,  and  South  Dakota.    These  markets  are  in  close  proximity  to  markets 
supplied by the Magellan system. 

The refined product transportation pipelines that also supply the markets supplied by the Cheyenne Refinery include 
Rocky Mountain, Magellan Mountain, Conoco, Medicine Bow, and Nustar Pipelines.  The Rocky Mountain Pipeline 
System  which  transports  the  Cheyenne  Refinery’s  products  to  Denver  also  transports  refined  products  from 
Wyoming and further north to Cheyenne and Denver.  The Medicine Bow pipeline delivers refined products from 
Sinclair  Wyoming.  The  Magellan  Mountain  pipeline  delivers  refined  products  directly  from  Kansas  but  those 
products may be supplied all the way from the Gulf Coast.  The Conoco and Nustar pipelines bring products in from 
the Texas panhandle. 

The  expansion  of  any  of  these  pipelines,  the  conversion  of  existing  pipelines  into  refined  products,  or  the 
construction  of  a  new  pipeline  into  our  markets  could  negatively  impact  the  supply  of  refined  products  in  our 
markets and our profitability. 

 We  depend  upon  HEP  for  a  substantial  portion  of  the  crude  supply  and  distribution  network  that  serve  our 
refineries and we own a significant equity interest in HEP.  

We currently own a 42% interest in HEP, including the 2% general partner interest. HEP operates a system of crude 
oil  and  petroleum  product  pipelines,  distribution  terminals  and  refinery  tankage  in  Arizona,  Idaho,  Kansas,  New 
Mexico,  Oklahoma,  Texas,  Utah,  Washington  and  Wyoming.  HEP  generates  revenues  by  charging  tariffs  for 
transporting petroleum products and crude oil through its pipelines, by leasing certain pipeline capacity to Alon, by 
charging fees for terminalling refined products and other hydrocarbons and storing and providing other services at 
its terminals.  HEP serves our refineries in New Mexico, Utah, Wyoming, Kansas and Oklahoma under several long-
term pipeline and terminal, tankage and throughput agreements expiring in 2019 through 2025.  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; 

-31-

 
 
 
 
 
 
 
 
 
   • 
   • 

  limitations on additional borrowings and other restrictions due to HEP’s debt covenants; and 
  other financial, operational and legal risks. 

The  occurrence  of  any  of  these  risks  could  directly  or  indirectly  affect  HEP’s  as  well  as  our  financial  condition, 
results  of  operations  and  cash  flows  as  HEP  is  a  consolidated  VIE.    Additionally,  these  risks  could  affect  HEP’s 
ability to continue operations which could affect their ability to serve our supply and distribution network needs.  

For  additional  information  about  HEP,  see  “Holly  Energy  Partners,  L.P.”  under  Items  1  and  2,  “Business  and 
Properties.”  

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  hostilities  in  the  Middle  East  or  other  sustained  military  campaigns  may  adversely  impact 
our results of operations.  

The long-term impacts of terrorist attacks, such as the attacks that occurred on September 11, 2001, and the threat of 
future terrorist attacks on the energy transportation industry in general, and on us in particular, are not known at this 
time.  Increased  security  measures  taken by  us  as  a  precaution  against possible  terrorist  attacks or  vandalism  have 
resulted in increased costs to our business. Future terrorist attacks could lead to even stronger, more costly initiatives 
or  regulatory  requirements.    Uncertainty  surrounding  continued  hostilities  in  the  Middle  East  or  other  sustained 
military campaigns may affect our operations in unpredictable ways, including disruptions of crude oil supplies and 
markets  for  refined  products,  and  the  possibility  that  infrastructure  facilities  could  be  direct  targets of,  or  indirect 
casualties  of,  an  act  of  terror.  In  addition,  disruption  or  significant  increases  in  energy  prices  could  result  in 
government-imposed  price  controls.    Any  one  of,  or  a  combination  of,  these  occurrences  could  have  a  material 
adverse effect on our business, financial condition and results of operations. 

Changes  in  the  insurance  markets  attributable  to  terrorist  attacks  could  make  certain  types  of  insurance  more 
difficult for us to obtain. Moreover, the insurance that may be available to us may be significantly more expensive 
than our existing insurance coverage.  Instability in the financial markets as a result of terrorism or war could also 
affect our ability to raise capital including our ability to repay or refinance debt. 

We may not be able to retain existing customers or acquire new customers.  

The renewal or replacement of existing contracts with our customers at rates sufficient to maintain current revenues 
and cash flows depends on a number of factors outside our control, including competition from other refiners and 
the demand for refined products in the markets that we serve. Loss of, or reduction in, amounts purchased by our 
major customers could have an adverse effect on us to the extent that, because of market limitations or transportation 
constraints, we are not able to correspondingly increase sales to other purchasers.  

Our petroleum business’ financial results are seasonal and generally lower in the first and fourth quarters of the 
year, which may cause volatility in the price of our common stock. 

Demand for gasoline products is generally higher during the summer months than during the winter months due to 
seasonal increases in highway traffic and road construction work. As a result, our results of operations for the first 

-32-

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
and  fourth  calendar  quarters  are  generally  lower  than  for  those  for  the  second  and  third  quarters.    The  effects  of 
seasonal demand for gasoline are partially offset by seasonality in demand for diesel fuel, which in the Southwest 
region of the United States is generally higher in winter months as east-west trucking traffic moves south to avoid 
winter  conditions  on  northern  routes.    However,  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 could have 
the effect of reducing demand for gasoline and diesel fuel which could result in lower prices and reduce operating 
margins.  

We may be unable to pay future dividends.  

We will only be able to pay dividends from our available cash on hand, cash from operations or borrowings under our 
credit agreement. The declaration of future dividends on our common stock will be at the discretion of our board of 
directors and will depend upon many factors, including our results of operations, financial condition, earnings, capital 
requirements, and restrictions in our debt agreements and legal requirements. We cannot assure you that any dividends 
will be paid or the frequency of such payments.  

Ongoing  maintenance  of  effective  internal  controls  in  accordance  with  Section  404  of  the  Sarbanes-Oxley  Act 
could cause us to incur additional expenditures of time and financial resources.   

We regularly document and test our internal control procedures in order to satisfy the requirements of Section 404 of 
the Sarbanes-Oxley Act, which requires annual management assessments of the effectiveness of our internal controls 
over  financial  reporting  and  a  report  by  our  independent  registered  public  accounting  firm  on  our  controls  over 
financial reporting.  If, in the future, we fail to maintain the adequacy of our internal controls and, as such standards 
are modified, supplemented or amended from time to time, we may not be able to ensure that we can conclude on an 
ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404 of the 
Sarbanes-Oxley  Act.  Failure  to  achieve  and  maintain  an  effective  internal  control  environment  could  cause  us  to 
incur substantial expenditures of management time and financial resources to identify and correct any such failure.    

Additionally,  the  failure  to  comply  with  Section  404  or  the  report  by  us  of  a  “material  weakness”  may  cause 
investors to lose confidence in our financial statements and our stock price may be adversely affected.  A “material 
weakness” is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there 
is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will 
not be prevented or detected on a timely basis.  If we fail to remedy any material weakness, our financial statements 
may be inaccurate, we may face restricted access to the capital markets, and our stock price may decline.   

Product liability claims and litigation could adversely affect our business and results of operations.  

Product liability is a significant commercial risk. Substantial damage awards have been made in certain jurisdictions 
against  manufacturers  and  resellers  based  upon  claims  for  injuries  caused  by  the  use  of  or  exposure  to  various 
products.  There can be no assurance that product liability claims against us would not have a material adverse effect 
on  our  business  or  results  of  operations.    Failure  of  our  products  to  meet  required  specifications  could  result  in 
product liability claims from our shippers and customers arising from contaminated or off-specification commingled 
pipelines and storage tanks and/or defective quality fuels. 

If the market value of our inventory declines to an amount less than our LIFO basis, we would record a write-
down of inventory and a non-cash charge to cost of sales, which would adversely affect our earnings. 

The nature of our business requires us to maintain substantial quantities of crude oil, refined petroleum product and 
blendstock inventories. Because crude oil and refined petroleum products are commodities, we have no control over 
the changing market value of these inventories. Because certain of our refining inventory is valued at the lower of 
cost or market value under the last-in, first-out (“LIFO”) inventory valuation methodology, we would record a write-
down of inventory and a non-cash charge to cost of sales if the market value of our inventory were to decline to an 
amount less than our LIFO basis.  A material write-down could affect our operating income and profitability. 

From  time  to  time,  our  cash  needs  may  exceed  our  internally  generated  cash  flow,  and  our  business  could  be 
materially and adversely affected if we are not able to obtain the necessary funds from financing activities. 

-33-

 
 
  
 
 
 
 
 
 
 
 
We have significant short-term cash needs to satisfy working capital requirements such as crude oil purchases which 
fluctuate with the pricing and sourcing of crude oil.  

We generally purchase crude oil for our refineries with cash generated from our operations.  If the price of crude oil 
increases  significantly,  we  may  not  have  sufficient  cash  flow,  available  cash  on  hand  or  borrowing  capacity,  and 
may not be able to sufficiently increase borrowing capacity, under our existing credit facilities to purchase enough 
crude oil to operate our refineries at desired capacity. Our failure to operate our refineries at desired capacity could 
have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of  operations.  We  also  have 
significant  long-term  needs  for  cash,  including  those  to  support  our  expansion  and  upgrade  plans,  as  well  as  for 
regulatory  compliance.  If  credit  markets  tighten,  it  may  become  more  difficult  to  obtain  cash  from  third  party 
sources. If we cannot generate cash flow or otherwise secure sufficient liquidity to support our short-term and long-
term capital requirements, we may not be able to comply with regulatory deadlines or pursue our business strategies, 
in which case our operations may not perform as well as we currently expect, and we could be subject to regulatory 
action. 

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 
enough 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  debt  agreements  contain  operating  and  financial  restrictions  that  might  constrain  our  business  and 
financing activities. 

The operating and financial restrictions and covenants in our credit facilities 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) maintenance of certain levels of the fixed charge coverage ratio; (ii) limitations 
on liens, investments, indebtedness and dividends; (iii) a prohibition on changes in control and (iv) restrictions on 
engaging in mergers, consolidations and sales of assets, entering into certain lease obligations, and making certain 
investments or capital expenditures. If we fail to satisfy the covenants set forth in the credit facility or another event 
of default  occurs under  the 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.  Should we desire to undertake a transaction that is prohibited 
by the covenants in our credit facilities, we will need to obtain consent under our credit facilities. Such refinancing 
may not be possible or may not be available on commercially acceptable terms.  In addition, our obligations under 
our  credit  facilities  are  secured  by  inventory,  receivables and  pledged  cash  assets.    If  we  are  unable  to  repay  our 
indebtedness  under our  credit  facilities  when due,  the  lenders  could  seek  to  foreclose on  the  assets or we  may  be 
required to contribute additional capital to our subsidiaries.  Any of these outcomes could have a material adverse 
effect on our business, financial condition and results of operations.  

Our business may suffer due to a change in the composition of our Board of Directors, or if any of our key senior 
executives or other key employees discontinue employment with us.  Furthermore, a shortage of skilled labor or 
disruptions in our labor force may make it difficult for us to maintain labor productivity.   

Our future performance depends to a significant degree upon the continued contributions of our senior management 
team and key technical personnel. We do not currently maintain key man life insurance, non-compete agreements, or 
employment agreements with respect to any member of our senior management team. The loss or unavailability to 
us of any member of our senior management team or a key technical employee could significantly harm us. We face 

-34-

 
 
 
 
 
 
 
 
 
competition  for  these  professionals  from  our  competitors,  our  customers  and  other  companies  operating  in  our 
industry.  To  the  extent  that  the  services of members  of our  senior  management  team  and key  technical  personnel 
would be unavailable to us for any reason, we may be required to hire other personnel to manage and operate our 
company. We may not be able to locate or employ such qualified personnel on acceptable terms, or at all.  

Furthermore, our operations require skilled and experienced laborers with proficiency in multiple tasks.  A shortage 
of trained workers due to retirements or otherwise could have an adverse impact on our labor productivity and costs 
and our ability to expand production in the event there is an increase in the demand for our products and services, 
which could adversely affect our operations.  

As of December 31, 2011, approximately 33% of our employees were represented by labor unions under collective 
bargaining agreements with various expiration dates.  We may not be able to renegotiate our collective bargaining 
agreements when they expire on satisfactory terms or at all. A failure to do so may increase our costs. In addition, 
our existing labor agreements may not prevent a strike or work stoppage at any of our facilities in the future, and any 
work stoppage could negatively affect our results of operations and financial condition.  

We  may  need to  use  current  cash  flow  to fund  our  postretirement  health  care  obligations,  which could have a 
significant adverse effect on our financial position.  

We  also  have  benefit  obligations  in  connection  with  our  unfunded  postretirement  health  care  plans  that  provide 
health care benefits as part of the voluntary early retirement program offered to eligible employees. As part of the 
early retirement program, we allow qualified retiring employees to continue coverage at a reduced cost under our 
group  medical  plans  until  normal  retirement  age.  Additionally,  we  maintain  an  unfunded  postretirement  medical 
plan whereby certain retirees between the ages of 62 and 65 can receive benefits paid by us. As of December 31, 
2011,  the  total  accumulated  postretirement  benefit  obligation  under  our  postretirement  medical  plans  was  $77.3 
million.    Increased  participation  in  this  program  and/or  increasing  medical  costs  may  affect  our  ability  to  pay 
required health care benefits causing us to have to divert funds away from other areas of the business to pay their 
costs. 

We  could  be  subject  to  damages  based  on  claims  brought  against  us  by  our  customers  or  lose  customers  as  a 
result of the failure of our products to meet certain quality specifications.  

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, off specification product could 
be  sent  out  to  public  gasoline  stations.    This  type  of  incident  could  result  in  liability  claims  regarding  damages 
caused  by  the  off  specification  fuel  or  could  impact  our  ability  to  retain  existing  customers  or  to  acquire  new 
customers, any of which could have a material adverse impact on our results of operations and cash flows. 

Item 1B.  Unresolved Staff Comments 

We do not have any unresolved staff comments.  

Item 3.  Legal Proceedings 

Commitment and Contingency Reserves  

We  periodically  establish  reserves  for  certain  legal  proceedings.  The  establishment  of  a  reserve  involves  an 
estimation  process  that  includes  the  advice  of  legal  counsel  and  subjective  judgment  of  management.  While 
management believes these reserves to be adequate, future changes in the facts and circumstances could result in the 
actual liability exceeding the estimated ranges of loss and amounts accrued.  

While the outcome and impact on us cannot be predicted with certainty, management believes that the resolution of 
these  proceedings  through  settlement  or  adverse  judgment  will  not  have  a  material  adverse  effect  on  our 

-35-

 
 
 
 
 
 
 
 
 
 
 
 
 
consolidated  financial  position  or  cash  flow.  Operating  results,  however,  could  be  significantly  impacted  in  the 
reporting periods in which such matters are resolved.  

Cut Bank Hill Environmental Claims   

Prior  to  the  sale  by  Holly  Corporation  of  the  Montana  Refining  Company  (“MRC”)  assets  in  2006,  MRC  (along 
with other companies) was the subject of several environmental claims at the Cut Bank Hill site in Montana. These 
claims include: (1) a U.S. Environmental Protection Agency (“EPA”) administrative order requiring MRC and other 
companies  to  undertake  cleanup  actions;  (2) a  U.S.  Coast  Guard  claim  against  MRC  and  other  companies  for 
response costs of $0.3 million in connection with its cleanup efforts at the Cut Bank Hill site; and (3) a unilateral 
order  by  the  Montana  Department  of  Environmental  Quality  (“MDEQ”)  directing  MRC  and  other  companies  to 
complete a remedial investigation and a request by the MDEQ that MRC and other companies pay $0.2 million to 
reimburse the State’s costs for remedial actions. MRC has denied responsibility for the requested EPA order and the 
MDEQ cleanup actions and the MDEQ and Coast Guard response costs, but has accepted an invitation by the other 
companies to participate in the group based on an allocation of approximately 10 percent of the group’s past and 
ongoing  investigation  and  other  costs.  This  matter  is  no  longer  considered  to  be  material  based  upon  information 
currently available to the Company and will not be disclosed in future SEC filings. 

Navajo Tank Fire   

On March 2, 2010, a tank caught fire while under construction. At the time of the incident, four individuals were 
working  on  top  of  the  tank.  These  individuals  were  all  employees  of  a  third-party  contractor  who  was  placing 
insulation on the tank. Two individuals sustained injuries and two individuals died as a result of the incident. Two 
wrongful death lawsuits and two personal injury lawsuits seeking damages, including punitive damages, were filed 
on  behalf  of  the  estates  of  the  two  deceased  workers  and  on  behalf  of  the  two  survivors  in  state  court  in  Dallas 
County, Texas (two lawsuits) and state court in Eddy County, New Mexico (two lawsuits). A confidential settlement 
was  reached  in  the  two  Texas  cases,  and  the  cases  have  been  dismissed.  Agreements  have  been  reached  for  the 
settlement  of  the  New  Mexico  cases,  and  those  agreements  are  being  documented.  It  is  anticipated  that  the  New 
Mexico cases will be dismissed shortly. These cases will no longer be reported in our SEC filings since they are not 
expected to be material due to our insurance coverage. 

New Mexico OHSB Complaint – Navajo Tank Fire   

On March 3, 2010, the New Mexico Occupational Health and Safety Bureau (“OHSB”), the New Mexico regulatory 
agency  responsible  for  enforcing  certain  state  occupational  health  and  safety  regulations,  which  are  identical  to 
Federal Occupational Safety and Health Administration (“OSHA”) regulations, commenced an inspection in relation 
to the tank fire that took place on March 2, 2010 at the Navajo facility in Artesia, New Mexico. On August 31, 2010, 
OHSB issued two citations to Navajo, alleging 10 willful violations and one serious violation of various construction 
safety  standards.  OHSB  proposed  penalties  in  the  amount  of  $0.7 million.  Navajo  filed  a  notice  of  contest, 
challenging  the  citations.  The  parties  commenced  settlement  negotiations  but  were  unable  to  reach  an  agreement, 
thus  OHSB  filed  an  administrative  complaint  with  New  Mexico  Occupational  Health  and  Safety  Review 
Commission (“OHSRC”) on December 20, 2010. Discovery is under way at this time.   Due to the complexity of the 
case and a recent substitution of counsel for New Mexico, OHSRC recently extended the schedule in this matter, 
setting the hearing to begin no sooner than January 2013. 

Discharge Permit Appeal – Tulsa West Facility   

HRM-Tulsa is party to parallel Oklahoma administrative and state district court proceedings involving a challenge to 
the terms of the Oklahoma Department of Environmental Quality (“ODEQ”) permit that governs the discharge of 
industrial  wastewater from  our Tulsa West  facility.  Pursuant  to  a  settlement  agreement  between  HRM  -Tulsa  and 
ODEQ,  both  proceedings  have  been  stayed  to  allow  ODEQ  to  issue  a  revised  permit  that  modifies  the  existing 
permit’s  requirements  for  toxicity  testing  and  for  managing  storm  flows.  The  parties  are  now  in  discussions 
regarding  the  appropriate  changes  in  the  permit  language  to  accomplish  these  modifications.  Once  agreed-upon 
revisions are made and become effective, both proceedings will be dismissed.  This matter is no longer considered to 
be  material  based  upon  information  currently  available  to  the  Company  and  will  not  be  disclosed  in  future  SEC 
filings.

Benzene Waste Operations Regulatory Proceedings – Tulsa East and West Facilities    

On July 13, 2011, the EPA issued a determination that HRM - Tulsa’s two refineries should be considered a single 
facility for purposes of a particular Clean Air Act regulation, the Benzene Waste Operations NESHAP. As a single 
facility,  the  refineries’  emissions  would  be  combined  for  purposes  of  assessing  whether  they  were  exceeding  the 
relevant regulatory threshold. We disagreed with this interpretation, however, and appealed the matter to the U.S. 
Court of Appeals for the Tenth Circuit. Shortly thereafter, the EPA withdrew its letter. In response, we dismissed the 
appeal.  At this time, no further proceedings are expected.   

Litigation Related to the Merger with Frontier Oil Corporation   

Twelve  substantially  similar  shareholder  lawsuits  styled  as  class  actions  were  filed  by  purported  Frontier 
shareholders  challenging  our  proposed  “merger  of  equals”  with  Frontier  and  naming  as  defendants  Frontier,  its 
board  of  directors  and,  in  certain  instances,  Holly  and  our  wholly  owned  subsidiary,  North  Acquisition,  Inc.,  as 
aiders  and  abettors.  To  date,  such  shareholder  actions  remain  pending  in  the  U.S.  District  Court  for  the  Northern 
District of Texas, and the U.S. District Court for the Southern District of Texas. One case filed in Laramie County, 
Wyoming  was  dismissed  without  prejudice.    Final  judgment  was  entered  by  the  Court  in  the  consolidated  Harris 
County, Texas cases on January 6, 2012, dismissing with prejudice all claims made by the class members.   

These  lawsuits  generally  allege  that  (1) the  consideration  received  by  Frontier’s  shareholders  in  the  merger  was 
inadequate, (2) the Frontier directors breached their fiduciary duties by, among other things, approving the merger at 
an  inadequate  price  under  circumstances  involving  certain  alleged  conflicts  of  interest,  (3) the  merger  agreement 
includes preclusive deal protection provisions, and (4) Frontier, and in some cases we and North Acquisition, Inc., 
aided  and  abetted  Frontier’s  directors  in  breaching  their  fiduciary  duties  to  Frontier’s  shareholders.  In  the  three 
federal court cases discussed more fully below, we and/or North Acquisition, Inc. were also alleged to have violated 
Section 14(a) and Section 20(a) of the Exchange Act of 1934 by soliciting proxies based on an allegedly false and/or 
misleading proxy statement concerning the merger.  

The  eight  lawsuits  filed  in  the  District  Courts  of  Harris  County,  Texas  (the  “Texas  State  Court  Lawsuits”)  were 
consolidated on March 25, 2011, under the caption: In re Frontier Oil Corporation, Cause No. 2011-11451 (first case 
filed February 22, 2011), and Interim Class Counsel was appointed on April 12, 2011. On September 12, 2011, the 
lead  plaintiff  and  the  defendants  in  the  Texas  State  Court  Lawsuits  submitted  a  Stipulation  and  Agreement  of 
Settlement  to  the  Court  for  preliminary  approval.  Pursuant  to  that  agreement,  the  actions  were  stayed  and  certain 
additional disclosures were made to Frontier’s shareholders on June 20, 2011. After a hearing on October 7, 2011, 
the  Court  granted  preliminary  approval  of  the  settlement  and  scheduled  a  final  settlement  hearing  for  January 6, 
2012.   On January 6, 2012, the Court approved a settlement and certified an opt-out class action, dismissed with 
prejudice all claims released by the terms of the settlement, and awarded attorneys’ fees and costs in the amount of 
$612,500 to counsel for the lead plaintiffs.   Shareholders who objected to the settlement  may appeal the Court’s 
decision to overrule their objections.  On January 19, 2012, one shareholder, whose objection related solely to the 
award  of  attorneys’  fees,  filed  a  request  for  findings  of  fact  and  conclusions  of  law  and  a  motion  for  new  trial.  
Generally, in the event that the order is reversed or modified on appeal, counsel for the lead plaintiffs shall refund 
the fee award consistent with such reversal or modification. 

The  lawsuit  filed  in  the U.S. District  Court for  the Northern District  of Texas  is  styled  Angelo  Chiarelli  v.  Holly 
Corporation, et al. (filed on March 2, 2011). On June 29, 2011, the plaintiff filed an amended complaint, and one 
month later, the parties filed an agreed motion to stay the case so that the proposed settlement in the Texas State 
Court Lawsuits could be considered and resolved by the state court. The motion to stay was granted on August 8, 
2011. On January 30, 2012, the parties filed a joint report informing the Court that the settlement in the Texas State 
Court  Lawsuits  had  been  approved  and  entered,  that  all  claims  in  the  Texas  State  Court  Lawsuits  had  been 
dismissed, and that Chiarelli neither objected to the settlement nor opted out of the class. 

The two remaining lawsuits filed in the U.S. District Court for the Southern District of Texas are consolidated under 
the caption: Tim Wilcox v. Frontier Oil Corporation, et al. (first case filed on March 7, 2011). We and our wholly 
owned subsidiary moved to dismiss the amended complaint on April 21, 2011, and the other defendants moved for 
dismissal  in  July  after  they  were  served.  On  June 24,  2011,  the  court  denied  plaintiffs’  motion  for  a  temporary 
restraining order and preliminary injunction to enjoin the proposed merger and prevent Frontier’s shareholders from 
voting on it. On August 9, 2011, the defendants filed an unopposed motion to stay the consolidated case in light of 
the proposed settlement of the Texas State Court Lawsuits.  On November 29, 2011, the court granted defendants’ 

-37-

 
 
unopposed  motion  to  stay  and  ordered  the  parties  to  file  a  report  on  the  status  of  the  proposed  settlement  of  the 
Texas State Court Lawsuits by January 13, 2012.  That same day, the court denied defendants’ motions to dismiss 
without  prejudice  to  refile.    On  January  13,  2012,  the  parties  filed  a  joint  report  informing  the  Court  that  the 
settlement in the Texas State Court Lawsuits had been approved and entered and that all claims in the Texas State 
Court Lawsuits had been dismissed. 

Due  to  recent  developments  we  no  longer  believe  these  matters  are  material  and,  accordingly,  they  will  not  be 
disclosed in future SEC filings. 

Unclaimed Property Audits  

A multi-state audit of legacy Holly Corporation’s unclaimed property compliance and reporting is being conducted 
by Kelmar Associates, LLC on behalf of eleven states. We are currently in the fourth year of this ongoing audit that 
covers the period 1981 – 2004. It is not yet possible to accurately estimate the amount, if any, that is owed to each of 
the states.  

A similar multi-state audit of legacy Frontier Oil Corporation’s unclaimed property compliance and reporting is also 
being conducted by Kelmar Associates, LLC on behalf of five states. The audit work began in December 2011.  It is 
not yet possible to accurately estimate the amount, if any, that might be owed to each of the states participating in 
this audit.  

We have determined that these audits are not material to the Company so they will no longer be reported in our SEC 
filings. 

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.

On  August  3,  2011,  our  Board  of  Directors  declared  a  two-for-one  stock  split,  payable  in  the  form  of  a  common 
stock dividend for each issued and outstanding share of our common stock.  The stock dividend was paid August 31, 
2011  to  all  shareholders  of  record  on  August  24,  2011.    All  references  to  share  and  per  share  amounts  in  this 
document and related disclosures have been adjusted to reflect the effect of the stock split for all periods presented.  

Under our common stock repurchase program repurchases are being made from time to time in the open market or 
privately  negotiated  transactions  based  on  market  conditions,  securities  law  limitations  and  other  factors.    The 
following table includes repurchases made under this program during the fourth quarter of 2011.

Additionally during the three months ended December 31, 2011, we withheld 18,322 shares of our common stock 
from  certain  executives  and  employees  in  the  amount  of  $0.5  million.    These  withholdings  were  made  under  the 
terms  of  our  share-based  compensation  unit  agreements  to  provide  funds  for  the  payment  of  payroll  and  income 
taxes due at vesting in the case of officers and employees who did not elect to satisfy such taxes by other means. 

As of February 16, 2012, we had approximately 48,000 stockholders, including beneficial owners holding shares in 
street name. 

We intend to consider the declaration of a dividend on a quarterly basis, although there is no assurance as to future 
dividends  since  they  are  dependent  upon  future  earnings,  capital  requirements,  our  financial  condition  and  other 
factors.    Our  credit  agreement  and  senior  notes  limit  the  payment  of  dividends.    See  Note  13  in  the  “Notes  to 
Consolidated Financial Statements” under Item 8, “Financial Statements and Supplementary Data.”

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. 

We  merged  with  Frontier  effective  July  1,  2011.    Accordingly,  this  document  includes  Frontier,  its  consolidated 
subsidiaries and the operations of the merged Frontier businesses effective July 1, 2011, but not prior to this date.  

OVERVIEW 

We  are  principally  an  independent  petroleum  refiner  that  produces  high-value  refined  products  such  as  gasoline, 
diesel  fuel,  jet  fuel,  specialty  lubricant  products,  and  specialty  and  modified  asphalt.    We  operate  five  refineries 
having a combined crude oil processing capacity of 443,000 barrels per day that serve markets throughout the Mid-
Continent, Southwest and Rocky Mountain regions of the United States.  Our refineries are located in El Dorado, 
Kansas, (the El Dorado Refinery), Tulsa, Oklahoma (the Tulsa Refineries) which comprise two production facilities, 
the Tulsa West and East facilities, a petroleum refinery in Artesia, New Mexico, which operates in conjunction with 
crude,  vacuum  distillation  and  other  facilities  situated  65  miles  away  in  Lovington,  New  Mexico  (the  Navajo 
Refinery), Cheyenne, Wyoming (the Cheyenne Refinery) and Woods Cross, Utah (the Woods Cross Refinery).    

On February 21, 2011, we entered into a merger agreement providing for a “merger of equals” business combination 
between  us  and  Frontier.    On  July  1,  2011,  North  Acquisition,  Inc.  a  direct  wholly-owned  subsidiary  of  Holly 
merged with and into Frontier, with Frontier surviving as a wholly-owned subsidiary of Holly.  Concurrent with the 
merger, we changed our name to HollyFrontier Corporation and changed the ticker symbol for our common stock 
traded on the New York Stock Exchange to “HFC.”  Subsequent to the merger and following approval by the post-
closing  board  of  directors  of  HollyFrontier,  Frontier  merged  with  and  into  HollyFrontier,  with  HollyFrontier 
continuing  as  the  surviving  corporation.    This  merger  combined  the  legacy  Frontier  refinery  operations,  the  El 
Dorado and Cheyenne Refineries, with Holly’s legacy refinery operations to form HollyFrontier. 

In accordance with the merger agreement, we issued approximately 102.8 million shares of HollyFrontier common 
stock  in  exchange  for  outstanding  shares  of  Frontier  common  stock  to  former  Frontier  stockholders.    Each 
outstanding share of Frontier common stock was converted into 0.4811 shares of HollyFrontier common stock with 
any fractional shares paid in cash.  The aggregate equity consideration paid in connection with the merger was $3.7 
billion.  This is based on our July 1, 2011 market closing price of $35.93 and includes a portion of the fair value of 
the outstanding equity-based awards assumed from Frontier that relates to pre-merger services.  

On  August  3,  2011,  our  Board  of  Directors  declared  a  two-for-one  stock  split,  payable  in  the  form  of  a  common 
stock dividend for each issued and outstanding share of our common stock.  The stock dividend was paid August 31, 
2011  to  all  shareholders  of  record  on  August  24,  2011.    All  references  to  share  and  per  share  amounts  in  this 
document and related disclosures have been adjusted to reflect the effect of the stock split for all periods presented.  

In  June  2009,  we  acquired  the  Tulsa  West  facility,  an  85,000  BPSD  refinery  located  in  Tulsa,  Oklahoma  from 
Sunoco and in December 2009, acquired the Tulsa East facility, a 75,000 BPSD refinery from Sinclair also located 
in Tulsa, Oklahoma.  We have integrated certain operations of the Tulsa Refineries, resulting in a combined crude 
processing rate of 125,000 BPSD. 

Sales  and  other  revenues  and  net  income  attributable  to  HollyFrontier  stockholders  were  $15,439.5  million  and 
$1,023.4  million,  $8,322.9  million  and  $104  million,  and  $4,834.3  million  and  $19.5  million  for  the  years  ended 
December 31, 2011, 2010 and 2009, respectively.  Our principal expenses are costs of products sold and operating 
expenses.  Our total operating costs and expenses were $13,708 million, $8,059.9 million and $4,754 million for the 
years ended December 31, 2011, 2010 and 2009, respectively.

income  plus  (i)  interest  expense,  net  of  interest  income,  (ii)  income  tax  provision,  and  (iii)  depreciation  and 
amortization.  EBITDA is not a calculation provided for under GAAP; however, the amounts included in the EBITDA 
calculation  are  derived  from  amounts  included  in  our  consolidated  financial  statements.    EBITDA  should  not  be 
considered as an alternative to net income or operating income as an indication of our operating performance or as an 
alternative to operating cash flow as a measure of liquidity.  EBITDA is not necessarily comparable to similarly titled 
measures  of  other  companies.    EBITDA  is  presented  here  because  it  is  a  widely  used  financial  indicator  used  by 
investors and analysts to measure performance.  EBITDA is also used by our management for internal analysis and as a 
basis for financial covenants.  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. 

Our operations are currently organized into two reportable segments, Refining and HEP.  Our operations that are not 
included  in  the  Refining  and  HEP  segments  are  included  in  Corporate  and  Other.    Intersegment  transactions  are 
eliminated in our consolidated financial statements and are included in Eliminations.

markets  asphalt  and  asphalt  products  in  Arizona,  New  Mexico,  Oklahoma,  Kansas,  Missouri,  Texas  and  northern 
Mexico. 

(2)  The HEP segment involves all of the operations of HEP effective March 1, 2008 (date of reconsolidation).  HEP owns 
and operates logistic assets consisting of petroleum product and crude oil pipelines and terminal, tankage and loading 
rack  facilities  in  the  Mid-Continent,  Southwest  and  Rocky  Mountain  regions  of  the  United  States.    Revenues  are 
generated by charging tariffs for transporting petroleum products and crude oil through its pipelines and by charging 
fees for terminalling petroleum products and other hydrocarbons, and storing and providing other services at its storage 
tanks and terminals.  Additionally, HEP owns a 25% interest in the SLC Pipeline that serves refineries in the Salt Lake 
City, Utah area.  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.

(10) Refining operating data for the year ended December 31, 2011 includes crude oil processed and products yielded from 
the El Dorado and Cheyenne Refineries for the period from July 1, 2011 through December 31, 2011 only, and averaged 
over the 365 days for the year ended December 31, 2011.  

(11) Refining operating data for the year ended December 31, 2009 includes crude oil processed and products yielded from 
the Tulsa Refineries for the period from June 1, 2009 through December 31, 2009 only, and averaged over the 365 days 
for the year ended December 31, 2009.   

Results of Operations – Year Ended December 31, 2011 Compared to Year Ended December 31, 2010 

Summary 
Net  income  attributable  to  HollyFrontier  Corporation  stockholders  for  the  year  ended  December  31,  2011  was 
$1,023.4 million ($6.46 per basic and $6.42 per diluted share) a $919.4 million increase compared to $104 million 
($0.98  per  basic  and  $0.97  per  diluted  share)  for  the  year  ended  December 31,  2010.    Net  income  increased  due 
principally to earnings attributable to the merged Frontier business operations (principally, El Dorado and Cheyenne 
Refineries) which are included in our results beginning July 1, 2011, and due to significantly higher refinery gross 
margins  during  2011.    Overall  refinery  gross  margins  for  the  year  ended  December  31,  2011  were  $20.64  per 
produced barrel compared to $8.79 for the year ended December 31, 2010. 

Overall production levels for the year ended December 31, 2011 increased by 47% over 2010 due to the inclusion of 
the El Dorado and Cheyenne Refinery operations following our merger with Frontier effective July 1, 2011.   

Sales and Other Revenues 
Sales  and  other  revenues  from  continuing  operations  increased  86%  from  $8,322.9  million  for  the  year  ended 
December 31, 2010 to $15,439.5 million for the year ended December 31, 2011, due principally to the inclusion of 
$4,183.8    million  in  revenues  attributable  to  the  El  Dorado  and  Cheyenne  Refinery  operations  and  the  effects  of 
increased refined product sales prices over the prior year.  The average sales price we received per produced barrel 
sold increased 30% from $91.06 for the year ended December 31, 2010 to $118.82 for the year ended December 31, 
2011.  Sales and other revenues for the years ended December 31, 2011 and 2010, include $46.4 million and $36 
million,  respectively,  in  HEP  revenues  attributable  to  pipeline  and  transportation  services  provided  to  unaffiliated 
parties.  

Cost of Products Sold 
Cost  of  products  sold  increased  72%  from  $7,367.1  million  for  the  year  ended  December  31,  2010  to  $12,680.1 
million for the year ended December 31, 2011, due principally to the inclusion of results from the El Dorado and 
Cheyenne Refinery operations, and due to higher crude oil costs.  The average price we paid per barrel of crude oil 
and feedstocks used in production and the transportation costs of moving the finished products to the market place 
increased 19% from $82.27 for the year ended December 31, 2010 to $98.18 for the year ended December 31, 2011.  

Gross Refinery Margins 
Gross  refining  margin  per  produced  barrel  increased  135%  from  $8.79  for  the  year  ended  December  31,  2010  to 
$20.64  for  the  year  ended  December  31,  2011,  due  to  an  increase  in  the  average  sales  price  we  received  per 
produced barrel sold, partially offset by an increase in the average price we paid per produced barrel of crude oil and 
feedstocks.  Gross refining margin does not include the effects of depreciation or amortization.  See “Reconciliations 
to Amounts Reported Under Generally Accepted Accounting Principles” following Item 7A of Part II of this Form 
10-K for a reconciliation to the income statement of prices of refined products sold and costs of products purchased. 

Operating Expenses 
Operating  expenses,  exclusive  of  depreciation  and  amortization  increased  48%  from  $504.4  million  for  the  year 
ended  December  31,  2010  to  $748.1  million  for  the  year  ended  December  31,  2011,  due  principally  to  costs 
attributable  to  the  El  Dorado  and  Cheyenne  Refinery  operations.    Also  contributing  to  a  much  lesser  extent  were 
increased payroll and maintenance costs attributable to the legacy Holly refining operations.  For the years ended 
December  2011  and  2010,  operating  expenses  include  $61.7  million  and  $52.4  million,  respectively,  in  costs 
attributable to HEP operations. 

General and Administrative Expenses 
General and administrative expenses increased 70% from $70.8 million for the year ended December 31, 2010 to 
$120.1 million for the year ended December 31, 2011. This includes $26.5 million in integration and severance costs 

-45-

 
 
 
 
 
 
 
 
 
associated with the merger integration. It also reflects higher payroll, equity based compensation costs and support 
costs  for  our  larger  organization.    For  the  years  ended  December  31,  2011  and  2010,  general  and  administrative 
expenses include $4.3 million and $5.4 million, respectively, in costs attributable to HEP operations.   

Depreciation and Amortization Expenses 
Depreciation and amortization increased 36% from $117.5 million for the year ended December 31, 2010 to $159.7 
million for the year ended December 31, 2011.  The increase was due principally to depreciation and amortization 
attributable to the El Dorado and Cheyenne Refinery operations and capitalized improvement projects.  For the years 
ended  December  31,  2011  and  2010,  depreciation  and  amortization  expenses  include  $31.5  million  and  $29.1 
million, respectively, in costs attributable to HEP operations. 

Interest Income 
Interest income for the year ended December 31, 2011 was $1.3 million compared to $1.2 million for the year ended 
December 31, 2010.  For the year ended December 31, 2011, interest income reflects higher cash investment levels 
in 2011.  Additionally, interest income for the year ended December 31, 2010 reflects interest received on income 
tax refunds. 

Interest Expense 
Interest expense was $78.3 million for the year ended December 31, 2011 compared to $74.2 million for the year 
ended December 31, 2010.  This increase reflects the write-off of $5 million of previously deferred financing costs 
due to the July 1, 2011 termination of our previous credit agreement and the inclusion of interest attributable to the 
senior  notes  assumed  upon  our  merger  with  Frontier.  Additionally,  during  2011  we  capitalized  $17.2  million  in 
interest  attributable  to  construction  projects.    For  the  years  ended  December  31,  2011  and  2010,  interest  expense 
included $38.2 million and $36.3 million, respectively, in costs attributable to HEP operations.  

Merger Transaction Costs 
For  the  year  ended  December  31,  2011,  we  recognized  merger  transaction  costs  of  $15.1  million  related  to  our 
merger with Frontier effective July 1, 2011.  These costs relate to legal, advisory and other professional fees that are 
directly attributable to the merger.  

Income Taxes 
Income taxes increased from $59.3 million for the year ended December 31, 2010 to $582 million for the year ended 
December 31, 2011 due to significantly higher pre-tax earnings for the year ended December 31, 2011 compared to 
2010.  Our effective tax rate, before consideration of earnings attributable to noncontrolling interests was 35.5% for 
the year ended December 31, 2011 compared to 30.8% for the year ended December 31, 2010.  Our effective tax 
rate  for  GAAP  disclosure  purposes  reflects  the  inclusion  of  non-taxable  earnings  attributable  to  noncontrolling 
interest  holders  in  the  denominator  of  our  effective  tax  rate  computation.    Our  actual  tax  rate  for  income  tax 
purposes did not increase. 

Results of Operations – Year Ended December 31, 2010 Compared to Year Ended December 31, 2009 

Summary 
Net income attributable to HollyFrontier Corporation stockholders for the year ended December 31, 2010 was $104 
million ($0.98 per basic and $0.97 per diluted share) an $84.4 million increase compared to $19.5 million ($0.20 per 
basic and diluted share) for the year ended December 31, 2009.  Net income increased due principally to increased 
sales  volumes  of  produced  refined  products  combined  with  higher  refinery  gross  margins  during  2010.    Overall 
refinery gross margins for the year ended December 31, 2010 were $8.79 per produced barrel compared to $7.21 for 
the year ended December 31, 2009. 

Overall  production  levels  for  the  year  ended  December  31,  2010  increased  by  49%  over  2009  due  to  production 
from our Tulsa Refineries acquired in June and December 2009 combined with production increases at our Navajo 
and Woods Cross Refineries.  Additionally, 2009 levels reflect lower production during the first quarter of 2009 due 
to scheduled downtime during a planned major maintenance turnaround at our Navajo Refinery.

Sales and Other Revenues 
Sales  and  other  revenues  from  continuing  operations  increased  72%  from  $4,834.3  million  for  the  year  ended 
December 31, 2009 to $8,322.9 million for the year ended December 31, 2010, due principally to the effects of a 
51% increase in year-over-year volumes of produced refined products sold combined with increased sales prices of 
produced  refined  products.    The  average  sales  price  we  received  per  produced  barrel  sold  increased  23%  from 
$74.06 for the year ended December 31, 2009 to $91.06 for the year ended December 31, 2010.  Sales and other 
revenues for the years ended December 31, 2010 and 2009, include $35.7 million and $45.2 million, respectively, in 
HEP revenues attributable to pipeline and transportation services provided to unaffiliated parties.  

Cost of Products Sold 
Cost of products sold increased 74% from $4,238 million for the year ended December 31, 2009 to $7,367.1 million 
for the year ended December 31, 2010, due principally to higher crude oil costs combined with a 51% increase in 
volumes of produced refined products sold.  The average price we paid per barrel of crude oil and feedstocks used in 
production  and  the  transportation  costs  of  moving  the  finished  products  to  the  market  place  increased  23%  from 
$66.85 for the year ended December 31, 2009 to $82.27 for the year ended December 31, 2010.  

Gross Refinery Margins 
Gross  refining  margin  per  produced  barrel  increased  22%  from  $7.21  for  the  year  ended  December  31,  2009  to 
$8.79 for the year ended December 31, 2010, due to an increase in the average sales price we received per produced 
barrel  sold,  partially  offset  by  an  increase  in  the  average  price  we  paid  per  produced  barrel  of  crude  oil  and 
feedstocks.  Gross refining margin does not include the effects of depreciation or amortization.  

Operating Expenses 
Operating  expenses,  exclusive  of  depreciation  and  amortization  increased  41%  from  $356.9  million  for  the  year 
ended  December  31,  2009  to  $504.4  million  for  the  year  ended  December  31,  2010,  due  principally  to  costs 
attributable to the operations of our Tulsa Refineries acquired in June and December 2009 and higher refinery utility 
costs.  For the years ended December 2010 and 2009, operating expenses include $52.4 million and $43.5 million, 
respectively, in costs attributable to HEP operations. 

General and Administrative Expenses 
General and administrative expenses increased 17% from $60.3 million for the year ended December 31, 2009 to 
$70.8  million  for  the  year  ended  December  31,  2010,  due  principally  to  costs  associated  with  the  support  and 
integration of our Tulsa operations and increased payroll costs.  For the years ended December 31, 2010 and 2009, 
general and administrative expenses include $5.4 million and $5.3 million, respectively, in costs attributable to HEP 
operations. 

Depreciation and Amortization Expenses 
Depreciation and amortization increased 19% from $98.8 million for the year ended December 31, 2009 to $117.5 
million for the year ended December 31, 2010.  The increase was due principally to depreciation and amortization 
attributable to our Tulsa facilities and capitalized refinery improvement projects in 2009 and 2010.  For the years 
ended  December  31,  2010  and  2009,  depreciation  and  amortization  expenses  include  $29.1  million  and  $26.5 
million, respectively, in costs attributable to HEP operations. 

Interest Income 
Interest income for the year ended December 31, 2010 was $1.2 million compared to $5 million for the year ended 
December 31, 2009.  Interest income was higher for the year ended December 31, 2009 due to interest received on 
income tax refunds and investments in higher yield marketable debt securities.  

Interest Expense 
Interest expense was $74.2 million for the year ended December 31, 2010 compared to $40.3 million for the year 
ended December 31, 2009.  The increase was due principally to interest incurred on our $300 million 9.875% senior 
notes issued in 2009 and HEP’s 8.25% senior notes issued in March 2010.  For the years ended December 31, 2010 
and  2009,  interest  expense  included  $36.3  million  and  $23.8  million,  respectively,  in  costs  attributable  to  HEP 
operations.

Income Taxes 
Income taxes increased from $7.5 million for the year ended December 31, 2009 to $59.3 million for the year ended 
December 31, 2010 due to significantly higher pre-tax earnings for the year ended December 31, 2010 compared to 
2009.  Our effective tax rate, before consideration of earnings attributable to noncontrolling interests was 30.8% for 
the year ended December 31, 2010 compared to 17% for the year ended December 31, 2009.  Our effective tax rate 
for GAAP disclosure purposes reflects the inclusion of non-taxable earnings attributable to noncontrolling interest 
holders in the denominator of our effective tax rate computation.  Our actual tax rate for income tax purposes did not 
increase. 

Discontinued Operations 
On  December  1,  2009,  HEP  sold  its  70%  interest  in  Rio  Grande  resulting  in  a  $14.5  million  gain.    Rio  Grande 
operations generated net earnings of $4.4 million for the year ended December 31, 2009 before taking into account 
HEP’s noncontrolling interest in the discontinued operations.  

LIQUIDITY AND CAPITAL RESOURCES 

HollyFrontier Credit Agreement 
On  July  1,  2011,  we  entered  into  a  $1  billion  senior  secured  credit  agreement  (the  “HollyFrontier  Credit 
Agreement”)  with  Union  Bank,  N.A.  as  administrative  agent  and  BNP  Paribas  as  syndication  agent,  and  certain 
lenders from time to time party thereto, and terminated our previous $400 million credit agreement.  Additionally, 
Frontier terminated its previous $500 million credit agreement. The HollyFrontier Credit Agreement matures in July 
2016 and may be used to fund working capital requirements, capital expenditures, acquisitions and general corporate 
purposes.  Obligations  under  the  HollyFrontier  Credit  Agreement  are  collateralized  by  our  inventory,  accounts 
receivables and certain deposit accounts and guaranteed by our material, wholly-owned subsidiaries.   

We were in compliance with all covenants at December 31, 2011.  At December 31, 2011, we had no outstanding 
borrowings  and  outstanding  letters  of  credit  totaled  $6.1  million  under  the  HollyFrontier  Credit  Agreement.    The 
unused commitment available under this credit agreement was $993.9 million at December 31, 2011.  

HEP Credit Agreement 
At December 31, 2011, HEP had a $275 million senior secured revolving credit facility expiring in February 2016 
(the “HEP Credit Agreement”) with an outstanding balance of $200 million.  On February 3, 2012, the HEP Credit 
Agreement  was  amended,  increasing  the  size  of  the  credit  facility  from  $275  million  to  $375  million  (the  “HEP 
Amended Credit Agreement”) and is available to fund capital expenditures, investments, acquisitions, distribution 
payments and working capital and for general partnership purposes.  It is also available to fund letters of credit up to 
a $50 million sub-limit and to fund distributions to unitholders up to a $30 million sub-limit.  The HEP Amended 
Credit  Agreement  expires  in  February  2016;  however,  in  the  event  that  the  6.25%  HEP  Senior  Notes  (discussed 
later) are not repurchased, defeased, refinanced, extended or repaid prior to September 1, 2014, the HEP Amended 
Credit Agreement will expire on that date. 

HEP’s obligations under the HEP Amended Credit Agreement are collateralized by substantially all of HEP’s assets 
(presented  parenthetically  in  our  Consolidated  Balance  Sheets).    Indebtedness  under  the  HEP  Amended  Credit 
Agreement is recourse to HEP Logistics Holdings, L.P., its general partner, and guaranteed by HEP’s wholly-owned 
subsidiaries.  Any recourse to the general partner would be limited to the extent of HEP Logistics Holdings, L.P.’s 
assets, which other than its investment in HEP, are not significant.  HEP’s creditors have no other recourse to our 
assets.  Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries.   

HollyFrontier Senior Notes  
Our senior notes consist of the following:  

• 
• 
• 

9.875% Senior Notes ($291.8 million principal amount maturing June 2017) 
6.875% Senior Notes ($150 million principal amount maturing November 2018)(1) 
8.5% Senior Notes ($200 million principal amount maturing September 2016)(1) 
(1) Represent senior notes assumed upon our July 1, 2011 merger with Frontier.

In June 2009, we issued $200 million in aggregate principal amount of the 9.875% Senior Notes maturing June 15, 
2017.  In October 2009, we issued an additional $100 million aggregate principal amount as an add-on offering to 
the 9.875% Senior Notes.   

We have additional senior notes that we assumed as a result of our July 1, 2011 merger with Frontier; the 6.875% 
Senior  Notes  having  an  aggregate  principal  amount  of  $150  million  maturing  November  15,  2018  and  the  8.5% 
Senior Notes  having an aggregate principal amount of $200 million maturing September 15, 2016. 

These  senior  notes  (collectively,  the  “HollyFrontier  Senior  Notes”)  are  unsecured  and  impose  certain  restrictive 
covenants,  including  limitations  on  our  ability  to  incur  additional  debt,  incur  liens,  enter  into  sale-and-leaseback 
transactions, pay dividends, enter into mergers, sell assets and enter into certain transactions with affiliates.  At any 
time when the HollyFrontier Senior Notes are rated investment grade by both Moody’s and Standard & Poor’s and 
no default or event of default exists, we will not be subject to many of the foregoing covenants.  Additionally, we 
have certain redemption rights under the HollyFrontier Senior Notes. 

HollyFrontier Financing Obligation 
In October 2009, we sold approximately 400,000 barrels of crude oil tankage at our Tulsa West facility as well as 
certain crude oil pipeline receiving facilities to an affiliate of Plains for $40 million in cash.  In connection with this 
transaction, we entered into a 15-year lease agreement with Plains, whereby we agreed to pay a fixed monthly fee 
for the exclusive use of this tankage as well as a fee for volumes received at the receiving facilities purchased by 
Plains.  Additionally, we have a margin sharing agreement with Plains under which we will equally share contango 
profits with Plains for crude oil purchased by them and delivered to our Tulsa West facility for storage.  Due to our 
continuing  involvement  in  these  assets,  this  sales  and  lease  transaction  has  been  accounted  for  as  a  financing 
obligation.  As a result, we retained these assets on our books and recorded a liability representing the $40 million in 
proceeds received.  

HEP Senior Notes 
HEP’s senior notes consist of the following:  

• 
• 

6.25% HEP Senior Notes ($185 million principal amount maturing March 2015) 
8.25% HEP Senior Notes ($150 million principal amount maturing March 2018) 

In  March  2010,  HEP  issued  $150  million  in  aggregate  principal  amount  of  8.25%  HEP  Senior  Notes  maturing 
March  15,  2018.    A  portion  of  the  $147.5  million  in  net  proceeds  received  was  used  to  fund  HEP’s  $93  million 
purchase of certain storage assets at our Tulsa East facility and Navajo Refinery Lovington facility  on March 31, 
2010.    Additionally,  HEP  used  a  portion  to  repay  $42  million  in  outstanding  HEP  Credit  Agreement  borrowings, 
with  the  remaining  proceeds  available  for  general  partnership  purposes,  including  working  capital  and  capital 
expenditures.  

HEP also has $185 million in aggregate principal amount of 6.25% HEP Senior Notes maturing March 1, 2015 that 
are registered with the SEC.   

These  HEP  senior  notes  (collectively,  the  “HEP  Senior  Notes”)  are  unsecured  and  impose  certain  restrictive 
covenants,  including  limitations  on  HEP’s  ability  to  incur  additional  indebtedness,  make  investments,  sell  assets, 
incur  certain  liens,  pay  distributions,  enter  into  transactions  with  affiliates,  and  enter  into  mergers.    At  any  time 
when the HEP Senior Notes are rated investment grade by both Moody’s and Standard & Poor’s and no default or 
event of default exists, HEP will not be subject to many of the foregoing covenants.  Additionally, HEP has certain 
redemption rights under the HEP Senior Notes.   

Indebtedness  under  the  HEP  Senior  Notes  is  recourse  to  HEP  Logistics  Holdings,  L.P.,  its  general  partner,  and 
guaranteed by HEP’s wholly-owned subsidiaries.  However, any recourse to the general partner would be limited to 
the  extent  of  HEP  Logistics  Holdings,  L.P.’s  assets,  which  other  than  its  investment  in  HEP,  are  not  significant.  
HEP’s creditors have no other recourse to our assets.  Furthermore, our creditors have no recourse to the assets of 
HEP and its consolidated subsidiaries.

HEP Common Unit Issuances 

2011 Issuances 
In December 2011, HEP issued 1,475,000 of its common units priced at $53.50 per unit.  Aggregate net proceeds of 
$75.8 million were used to repay a portion of the $150 million in promissory notes issued to us in connection with 
HEP’s November 9, 2011 asset acquisition from us.  This repayment to us is eliminated in our consolidated financial 
statements. 

In November 2011, HEP issued 3,807,615 of its common units to us as partial consideration for its purchase from us 
of certain tankage, loading rack and crude receiving assets located at our El Dorado and Cheyenne Refineries.    

2009 Issuances 
In December 2009, HEP issued 1,373,609 of its common units having a value of $53.5 million to Sinclair as partial 
consideration of its purchase of Sinclair’s Tulsa logistics assets.  

In November 2009, HEP issued 2,185,000 of its common units priced at $35.78 per unit. Aggregate net proceeds of 
$74.9  million  were  used  to  fund  the  cash  portion  of  HEP’s  December  1,  2009  asset  acquisitions,  to  repay 
outstanding borrowings under HEP’s credit agreement and for general partnership purposes.   

Additionally in May 2009, HEP issued 2,192,400 of its common units priced at $27.80 per unit.  Net proceeds of 
$58.4 million were used to repay outstanding borrowings under HEP’s credit agreement and for general partnership 
purposes. 

Liquidity  
We believe our current available cash on hand, along with future internally generated cash flow and funds available 
under  our  credit  facilities  will  provide  sufficient  resources  to  fund  currently  planned  capital  projects  and  our 
liquidity needs for the foreseeable future.  In addition, components of our growth strategy include construction of 
new  refinery  processing  units  and  the  expansion  of  existing  units  at  our  facilities  and  selective  acquisition  of 
complementary assets for our refining operations intended to increase earnings and cash flow.  Our ability to acquire 
complementary assets will be dependent upon several 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 many other factors beyond our control. 

As of December 31, 2011, our cash, cash equivalents and investments in marketable securities totaled $1.8 billion. 
We consider all highly-liquid instruments with a maturity of three months or less at the time of purchase to be cash 
equivalents.    Cash  equivalents  are  stated  at  cost,  which  approximates  market  value,  and  are  invested  primarily  in 
conservative, highly-rated instruments issued by government or municipal entities with strong credit standings. 

In September 2011, our Board of Directors approved a stock repurchase program of up to $100 million to repurchase 
common stock in the open market or through privately negotiated transactions. As of December 31, 2011, we had 
repurchased 586,123 shares at a cost of $17.8 million under this stock repurchase program. 

In  January  2012,  our  Board  of  Directors  approved  a  $350  million  stock  repurchase  program,  which  replaced  the 
existing  $100  million  stock  repurchase  program.    The  timing  and  amount  of  stock  repurchases  will  depend  on 
market  conditions,  corporate,  regulatory  and  other  relevant  considerations.  The  stock  repurchase  program  may  be 
discontinued at any time by the Board of Directors. 

Cash  and  cash  equivalents  increased  by  $1,349.8  million  during  the  year  ended  December  31,  2011.    Net  cash 
provided  by  operating  activities  and  investing  activities  of  $1,338.4  million  and  $228.5  million,  respectively, 
exceeded cash used for financing activities of $217.1 million.  Working capital increased by $1,716.5 million during 
2011.

Additionally, turnaround expenditures were $35 million and $33.5 million for the years ended December 31, 2010 
and 2009, respectively. 

Cash Flows - Investing Activities and Planned Capital Expenditures 

Year Ended December 31, 2011 Compared to Year Ended December 31, 2010 
Net  cash  flows  provided  by  investing  activities  were  $228.5  million  for  the  year  ended  December  31,  2011 
compared to net cash flows used for investing activities $213.2 million for the year ended December 31, 2010, an 
increase  of  $441.7  million.    Current  year  investing  activities  reflect  a  net  cash  inflow  due  to  an  $872.7  million 
increase in cash and cash equivalents as a result of our July 1, 2011 merger with Frontier.  Cash expenditures for 
properties, plant and equipment for 2011 increased to $374.2 million compared to $213.2 million for 2010.  These 
include HEP capital expenditures of $39.3 million and $25.1 million for the years ended December 31, 2011 and 
2010,  respectively.    Current  year  capital  expenditures  include  $164.3  million  in  costs  to  construct  the  UNEV 
Pipeline,  which  was  mechanically  complete  in  November  2011.  During  the  year  ended  December  31,  2011,  we 
invested $9.1 million in Sabine Biofuels, a development stage biodiesel production facility. Additionally for the year 
ended  December  31,  2011,  we  invested  $561.9  million  in  marketable  securities  and  received  proceeds  of  $301 
million from the sale of our marketable securities. 

Year Ended December 31, 2010 Compared to Year Ended December 31, 2009 
Net cash flows used for investing activities were $213.2 million for the year ended December 31, 2010 compared to 
$534.6  million  for  the  year  ended  December  31,  2009,  a  decrease  of  $321.4  million.    Cash  expenditures  for 
properties, plant and equipment for 2010 decreased to $213.2 million compared to $302.6 million for 2009.  These 
include  HEP  capital  expenditures  of  $25.1  million  and  $33  million  for  the  years  ended  December  31,  2010  and 
2009,  respectively.    Capital  expenditures were  significantly  lower  in 2010  due  to  a higher  level of  capital  project 
initiatives in 2009 including refinery expansion projects.  During the year ended December 31, 2009, we paid cash

consideration  of  $267.1  million  in  connection  with  the  Tulsa  West  and  East  facility  acquisitions,  invested  $175.9 
million  in  marketable  securities  and  received  proceeds  of  $230.3  million  from  the  sale  or  maturity  of  marketable 
securities.  Additionally, HEP acquired logistics and storage assets from an affiliate of Sinclair for $25.7 million and 
made a $25.5 million joint venture contribution to the SLC Pipeline.  In December 2009, HEP sold its 70% interest 
in Rio Grande for $35 million.  The cash proceeds received are presented net of Rio Grande’s December 1, 2009 
cash balance of $3.1 million.  

Planned Capital Expenditures 

HollyFrontier Corporation   

Each  year  our  Board  of  Directors  approves  our  annual  capital  budget  which  includes  specific  projects  that  our 
management  is  authorized  to  undertake.   Additionally,  when  conditions  warrant  or  as  new  opportunities  arise, 
additional projects may be approved.  The funds appropriated for a particular capital project may be expended over a 
period  of  several  years,  depending  on  the  time  required  to  complete  the  project.   Therefore,  our  planned  capital 
expenditures for a given year consist of expenditures appropriated in that year’s capital budget plus expenditures for 
projects appropriated in prior years which have not yet been completed.  Our appropriated capital budget for 2012 is 
$257 million including both sustaining capital and major capital projects.  We expect to spend approximately $350 
million  in  cash  for  capital  projects  in  2012,  including  projects  approved  in  prior  years. In  addition,  we  expect  to 
spend $120 million on refinery turnarounds and tank maintenance.  Refinery turnaround spending is amortized over 
the useful life of the turnaround while tank maintenance is expensed as incurred.  Our new capital appropriation for 
2012 and expected cash spending are as follows:

A significant portion of our current capital spending is associated with compliance-oriented capital improvements.  
This spending is required due to existing consent decrees (for projects including FCCU flu gas scrubbers and tail gas 
treatment units), federal fuels regulations (particularly, MSAT2 which mandates a reduction in the benzene content 
of  blended  gasoline),  refinery  waste  water  treatment  improvements  and  other  similar  initiatives.    Our  refinery 
operations and related emissions are highly regulated at both federal and state levels, and we invest in our facilities 
as  needed  to  remain  in  compliance  with  these  standards.    Additionally,  when  faced  with  new  emissions  or  fuels 
standards, we seek to execute projects that facilitate compliance and also improve the operating costs and/or yields 
of associated refining processes.  

El Dorado Refinery 
Newly appropriated capital projects at the El Dorado Refinery include naphtha splitting and aromatics recovery unit 
revamps to reduce benzene in gasoline (MSAT2 compliance) and installation of a new tail gas treatment unit with 
our sulfur recovery facilities as required under an existing EPA consent decree.  Also included in the 2012 capital 
budget are yield improvement projects that address both the FCC Unit and the Coker.  A previously appropriated 
project which we expect to complete during 2012 is the replacement of an existing Coker furnace with more current 
furnace technology.  This project is expected to improve Coker on-stream factor and reduce fuel consumption. We 
expect to complete this project in late 2012.

Tulsa Refineries 
The  most  significant  newly  appropriated  capital  project  for  our  Tulsa  Refineries  is  conversion  of  a  propane  de-
asphalt  unit  to  ROSE  technology.    This  project  is  expected  to  cost  $25  million  and  will  increase  processing  of 
vacuum  tower  bottoms,  increase  the  production  of  bright  stock  lube,  reduce  energy  consumption,  and  allow  the 
shutdown of a low-pressure steam boiler.   Projects still underway from prior appropriations include a $58 million 
project to recover sulfur from the refinery fuel gas system and to shut down another low pressure steam boiler by 
electrification of turbine drivers.   The sulfur recovery project is required to comply with our EPA consent decree 
but is being enhanced so as to increase our capacity to run lower priced sour / heavy crude in Tulsa.  We are also 
executing  an  LPG  recovery  project  in  Tulsa  at  an  estimated  total  cost  of  $28  million.    This  project  will  improve 
overall  liquid  yields  and  enable  us  to  substitute  lower-priced  natural  gas  for  LPG’s  currently  being  consumed  as 
refinery fuel.  Other projects underway in Tulsa involve replacement of an existing vacuum tower and improvements 
to our wastewater treatment plants and storm water retention systems.   

Navajo Refinery 
We have approved a new project for the Navajo Refinery to remove sulfur and other contaminants from the crude 
unit off-gas stream; this will improve liquid yields and reduce refinery fuel costs.  Current spending on previously 
appropriated projects includes an MSAT2 project (naphtha splitting and benzene saturation) to reduce reliance on 
benzene  credits  purchases,  as  well  as  expenditures  to  improve  the  Artesia  waste  water  handling  and  processing 
facilities. 

Cheyenne Refinery 
We have approved four new compliance projects for the Cheyenne Refinery including wastewater treatment plant 
improvements,  a  wet  gas  scrubber  for  the  FCC  unit  to  reduce  particulate  and  other  emissions,  MSAT2  related 
investments  to  reduced  benzene  in  gasoline,  and  spending  for  additional  tail  gas  unit  associated  with  our  sulfur 
recovery facilities.  We also plan to improve metallurgy on portions of the Cheyenne Refinery’s delayed coking unit. 
These new major capital appropriations total approximately $60 million, and we expect to spend approximately 30% 
of this amount on these projects during 2012.  Expenditures for MSAT2 compliance projects were accelerated by 
approximately  one  year  at  each  of  the  Cheyenne  and  El Dorado  Refineries  due  to  the  Holly-Frontier  merger,  this 
followed our loss of a small refiner exemption that previously provided for delayed compliance with this standard.  

Woods Cross Refinery 
We plan to significantly expand our Woods Cross Refinery in response to increased availability of locally-produced 
black wax crude oil.  We have announced a 10-year crude supply agreement with Newfield Exploration Company 
under  which  we  will  purchase  20,000  bpd  of  waxy  crudes  (black  and  yellow  wax).    Our  expansion  project  will 
increase crude processing capacity of Woods Cross from 31,000 bpd to 45,000 bpd.  Most of the incremental crude 
supply  is  expected  to  be  waxy  crude,  and  the  expansion  is  being  configured  to  create  high  liquid  yields  and 
relatively large proportions of additional gasoline and diesel fuel in comparison to the increased crude charge.  We 
expect  this  $225  million  project  to  have  a  pre-tax  payback  period  of  approximately  two  years,  and  we  expect  to 
complete  the  expansion  in  approximately  the  fourth  quarter  of  2014.    Our  execution  of  this  project  is  subject  to 
certain contingencies, including our receipt of required emissions and other permits.  Also at Woods Cross, we have 
two significant compliance projects authorized in prior year appropriations.  The first of these involves installation 
of a wet gas scrubber on the FCC unit to reduce particulate and other emissions and the second relates to MSAT2 
compliance which will require naphtha fractionation and benzene saturation.  

UNEV 
The  UNEV  Pipeline,  in  which  we  own  a  75%  equity  interest,  was  mechanically  completed  in  November  2011.  
Linefill  and  startup  procedures  commenced  thereafter,  and  the pipeline and  associated  product  terminals  in  Cedar 
City, Utah and Las Vegas, Nevada were operational during the first quarter of 2012.  We believe that the UNEV 
Pipeline will play an important role in offsetting seasonal declines in product demand, characteristic of the Salt Lake 
City refined products market.  We also believe that UNEV will facilitate a growing north-to-south flow of refined 
products  which  we  expect  will  result  from  the  advantaged  crude  oil  economics  enjoyed  by  PADD  IV  (Rocky 
Mountain)  refiners.    We  plan  to  spend  an  additional  $16  million  in  2012  on  capital  items  associated  with  the 
completion and startup of UNEV, and our estimate of total installed cost is now $308 million for our 75% interest in 
this pipeline.

Regulatory compliance items or other presently existing or future environmental regulations / consent decrees could 
cause us to make additional capital investments beyond those described above and incur additional operating costs 
in order to meet applicable requirements. 

HEP 

Each  year  the  Holly  Logistic  Services,  L.L.C.  board  of  directors  approves  HEP’s  annual  capital  budget,  which 
specifies capital projects that HEP management is authorized to undertake.  Additionally, at times when conditions 
warrant or as new opportunities arise, special projects may be approved.  The funds allocated for a particular capital 
project  may  be  expended  over  a  period  of  several  years,  depending  on  the  time  required  to  complete  the  project.  
Therefore, HEP’s planned capital expenditures for a given year consist of expenditures approved for capital projects 
included in its current year capital budget as well as, in certain cases, expenditures approved for capital projects in 
capital budgets for prior years.  The 2012 HEP capital budget is comprised of $8.9 million for maintenance capital 
expenditures and $25.8 million for expansion capital expenditures.  

HEP has recently made certain modifications to its crude oil gathering and trunk line system that have effectively 
increased HEP’s ability to gather and transport an additional 10,000 bpd of Delaware Basin crude oil in response to 
increased drilling activity in southeast New Mexico.  Furthermore, HEP has developed a project to replace a 5-mile 
section  of  this  pipeline  system  that  will  allow  for  an  additional  15,000  bpd  of  capacity  that  will  be  executed  as 
needed if Delaware Basin crude volumes continue to increase.  This project is estimated to cost approximately $2 
million.  HEP has a second project which consists of the reactivation and conversion to crude oil service of a 70-
mile, 8-inch petroleum products pipeline owned by HEP.  Once in service, this pipeline will initially be capable of 
transporting up to 35,000 bpd of crude oil from southeast New Mexico to third-party common carrier pipelines in 
west Texas for further transport to major crude oil markets.  The scope of this project is being finalized.  Subject to 
receipt of acceptable shipper support and board approval, this project could be operational in early 2013. 

Cash Flows - Financing Activities 

Year Ended December 31, 2011 Compared to Year Ended December 31, 2010 
Net cash flows used by financing activities were $217.1 million for the year ended December 31, 2011 compared to 
cash flows provided by financing activities of $34.5 million for the year ended December 31, 2010, a decrease of 
$251.6  million.    During  2011,  we  paid  $8.2  million  principal  on  our  senior  notes,  paid  $1.2  million  under  our 
financing obligation to Plains, purchased $42.8 million in common stock from employees to provide funds for the 
payment of payroll and income taxes due upon the vesting of certain share-based incentive awards and also under 
the  stock  repurchase  program,  paid  $252.1  million  in  dividends,  received  a  $33.5  million  contribution  from  our 
UNEV  Pipeline  joint  venture  partner  and  recognized  $1.8  million  excess  tax  benefits  on  our  equity  based 
compensation.    Also  during  this  period,  HEP  received  $75.8  million  in  net  proceeds  upon  the  issuance  of  HEP

(1)  We may be required to make cash outlays related to our unrecognized tax benefits.  However, due to the uncertainty of the 
timing  of  future  cash  flows  associated  with  our  unrecognized  tax  benefits,  we  are  unable  to  make  reasonably  reliable 
estimates  of  the  period  of  cash  settlement,  if  any,  with  the  respective  taxing  authorities.    Accordingly,  unrecognized  tax 
benefits  of  $2.4 million  as  of  December  31,  2011 have  been excluded  from  the  contractual  obligations  table  above.   For 
further information related to unrecognized tax benefits, see Note 15 to the Consolidated Financial Statements. 

(2)  Amounts  shown  do  not  include  commitments  to  deliver  barrels  of  crude  oil  held  for  other  parties  at  our  refineries.   We 
periodically  hold  crude  oil owned  by  third  parties  in  the  storage  tanks  at  our  refineries,  which  may  be  run  through 
production.  We will be obligated to deliver these stored barrels of crude oil upon the other party’s request.

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  to  the  Consolidated  Financial  Statements  “Description  of 
Business and Summary of Significant Accounting Policies.” 

Inventory Valuation  
Our crude oil and refined product inventories are stated at the lower of cost or market.  Cost is determined using the 
LIFO inventory valuation methodology and market is determined using current estimated selling prices.  Under the 
LIFO method, the most recently incurred costs are charged to cost of sales and inventories are valued at the earliest 
acquisition costs.  In periods of rapidly declining prices, LIFO inventories may have to be written down to market 
value due to the higher costs assigned to LIFO layers in prior periods.  In addition, the use of the LIFO inventory 
method may result in increases or decreases to cost of sales in years when inventory volumes decline and result in 
charging cost of sales with LIFO inventory costs generated in prior periods.  As of December 31, 2011, many of our 
LIFO inventory layers were valued at historical costs that were established in years when price levels were generally 
lower; therefore, our results of operation are less sensitive to current market price reductions.  As of December 31, 
2011, the excess of current cost over the LIFO inventory value of our crude oil and refined product inventories was 
$378 million.  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. 

Deferred Maintenance Costs 
Our refinery units require regular major maintenance and repairs that are commonly referred to as “turnarounds.”  
Catalysts  used  in  certain  refinery  processes  also  require  routine  “change-outs.”    The  required  frequency  of  the 
maintenance varies by unit and by catalyst, but generally is every two to five years.  In order to minimize downtime 
during turnarounds, we utilize contract labor as well as our maintenance personnel on a continuous 24 hour basis.  
Whenever  possible,  turnarounds  are  scheduled  so  that  some  units  continue  to  operate  while  others  are  down  for 
maintenance.    We  record  the  costs  of  turnarounds  as  deferred  charges  and  amortize  the  deferred  costs  over  the 
expected periods of benefit.

Long-lived Assets 
We calculate depreciation and amortization based on estimated useful lives and salvage values of our assets.  When 
assets are placed into service, we make estimates with respect to their useful lives that we believe are reasonable.  
However, factors such as competition, regulation or environmental matters could cause us to change our estimates, 
thus impacting the future calculation of depreciation and amortization.  We evaluate long-lived assets for potential 
impairment by identifying whether indicators of impairment exist and, if so, assessing whether the long-lived assets 
are recoverable from estimated future undiscounted cash flows.  The actual amount of impairment loss, if any, to be 
recorded  is  equal  to  the amount by which a  long-lived  asset’s  carrying value  exceeds its  fair value.   Estimates  of 
future discounted cash flows and fair values of assets require subjective assumptions with regard to future operating 
results  and  actual  results  could  differ  from  those  estimates.    No  impairments  of  long-lived  assets  were  recorded 
during the years ended December 31, 2011, 2010 and 2009. 

Intangibles and Goodwill 
Intangible assets are assets (other than financial assets) that lack physical substance.  Goodwill represents the excess 
of the cost of an acquired entity over the fair value of the assets acquired less liabilities assumed.  Goodwill acquired 
in a business combination and intangible assets with indefinite useful lives are not amortized while intangible assets 
with  finite  useful  lives  are  amortized  on  a  straight-line  basis.    Goodwill  and  intangible  assets  not  subject  to 
amortization are tested for impairment annually or more frequently if events or changes in circumstances indicate 
the  asset  might  be  impaired.   There were no  impairments  of  intangible  assets  or goodwill  during  the  years  ended 
December 31, 2011, 2010 and 2009. 

Variable Interest Entity 
HEP is a VIE as defined under GAAP.  A VIE is legal entity whose equity owners do not have sufficient equity at 
risk or a controlling interest in the entity, or have voting rights that are not proportionate to their economic interest.  
As the general partner of HEP, we have the sole ability to direct the activities of HEP that most significantly impact 
HEP’s economic performance.  Additionally, since our obligation to absorb losses and receive benefits from HEP 
are significant to HEP, we are HEP’s primary beneficiary and therefore we consolidate HEP.   

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. 

New Accounting Pronouncements 

Presentation of Comprehensive Income 
In  June  2011,  an  accounting  standard  update  was  issued  that  requires  the  presentation  of  net  income  and  other 
comprehensive income in one continuous statement or in two separate, but consecutive, statements and eliminates 
the option to present the components of other comprehensive income in the statement of stockholders’ equity.  This 
standard is effective January 1, 2012 and will be applied retrospectively.  This update will not have an impact on our 
financial condition, results of operations and cash flows. 

Intangibles — Goodwill and Other: Testing Goodwill for Impairment 
In September 2011, an accounting standard update was issued that allows entities an option to first assess qualitative 
factors  to  determine  whether  it  is  necessary  to  perform  the  two-step  quantitative  goodwill  impairment  test.    This 
standard is effective for annual and interim goodwill impairment testing beginning January 1, 2012.  This standard 
will not have an impact on our financial condition, results of operations and cash flows. 

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 

-57-

 
 
 
 
 
 
 
 
 
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 to mitigate price exposure with 
respect to: 

• 
• 
• 
• 
• 

our inventory positions; 
natural gas purchases; 
costs of crude oil;   
prices of refined products; and 
our refining margins. 

As  of December  31, 2011, we  have  outstanding  swap  contracts  serving as cash flow  hedges  against price  risk on 
forecasted 2012 purchases of 14,640,000 barrels of WTI crude oil and forecasted sales of 7,320,000 barrels of ultra-
low sulfur diesel and 7,320,000 barrels of conventional unleaded gasoline.  In the aggregate, these cash flow hedges 
effectively hedge our gross margin on forecasted gasoline and diesel sales, totaling 40,000 BPD in 2012. 

We  also  have  swap  contracts  that  lock  in  the  spread  between  gasoline  and  butane  on  forecasted  sales  (112,500 
barrels of gasoline through January 2012) and NYMEX futures contracts to lock in prices on forecasted sales and 
purchases of inventory (292,000 barrels and 411,000 barrels, respectively, through 2013). 

Interest Rate Risk Management 
HEP uses interest rate swaps to manage its exposure to interest rate risk.  

As of December 31, 2011 HEP has an interest rate swap contract that hedges HEP’s exposure to the cash flow risk 
caused by the effects of LIBOR changes on a $155 million HEP Credit Agreement advance.  This interest rate swap 
effectively converts $155 million of LIBOR based debt to fixed rate debt having an interest rate of 0.99% plus an 
applicable margin, currently 2.50%, which equaled an effective interest rate of 3.49% as of December 31, 2011. This 
swap matures in February 2016. 

The following table presents balance sheet locations and related fair values of outstanding derivative instruments. 
These amounts are presented on a gross basis in accordance with GAAP disclosure requirements and do not reflect 
the netting of asset or liability positions permitted under the terms of master netting arrangements.  Therefore, they 
are not equal to amounts presented in our consolidated balance sheets.  Additionally, we held $30 million of cash on 
margin  at  December  31,  2011  to  collateralize  certain  counterparty  positions.    These  deposits  have  an  offsetting 
current liability on our balance sheet and are not included in the amounts below.

Publicly  available  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 swap contracts.  These counterparties 
are  large  financial  institutions.    We  have  not  experienced,  nor  do  we  expect  to  experience,  any  difficulty  in  the 
counterparties honoring their commitments. 

The  market  risk  inherent  in  our  fixed-rate  debt  and  positions  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  our  earnings  or  cash  flows.    The  outstanding  principal,  estimated  fair  value  and 
estimated  change  in  fair  value  assuming  a  hypothetical  10%  change  in  the  yield-to-maturity  rates  for  these  debt 
instruments as of December 31, 2011 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, 2011, borrowings outstanding under the HEP Credit Agreement were $200 million.  By means of 
its cash flow hedge, HEP has effectively converted the variable rate on $155 million of outstanding principal to a 
fixed rate of 3.49 %.  For the unhedged $45 million portion, a hypothetical 10% change in interest rates applicable to 
the HEP Credit Agreement would not materially affect cash flows. 

At  December  31,  2011,  cash  and  cash  equivalents  included  investments  in  investment  grade,  highly  liquid 
investments with maturities of three months or less at the time of purchase and hence the interest rate market risk 
implicit  in  these  cash  investments  is  low.    Due  to  the  short-term  nature  of  our  cash  and  cash  equivalents,  a 
hypothetical 10% increase in interest rates would not have a material effect on the fair market value of our portfolio.

Since  we  have  the  ability  to  liquidate  this  portfolio,  we  do  not  expect  our  operating  results  or  cash  flows  to  be 
materially affected by the effect of a sudden change in market interest rates on our investment portfolio. 

Our operations are subject to normal hazards of operations, including fire, explosion and weather-related perils.  We 
maintain various insurance coverages, including business interruption insurance, subject to certain deductibles.  We 
are  not  fully  insured  against  certain  risks  because  such  risks  are  not  fully  insurable,  coverage  is  unavailable,  or 
premium costs, in our judgment, do not justify such expenditures. 

We have a risk management oversight committee that is made up of members from our senior management.  This 
committee oversees our risk enterprise program, monitors our risk environment and provides direction for activities 
to mitigate identified risks that may adversely affect the achievement of our goals.

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 
income from continuing operations 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 from continuing operations.

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 an absolute 
basis. 

Refinery gross margin per barrel is the difference between average net sales price and average cost of products per 
barrel of produced refined products.  Net operating margin per barrel is the difference between refinery gross margin 
and  refinery  operating  expenses  per  barrel  of  produced  refined  products.    These  two  margins  do  not  include  the 
effect of 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.

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, 2011 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.  Based  on  this  assessment, 
management  concludes  that,  as  of  December  31,  2011,  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, 2011.  That report appears on page 
65.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  

The Board of Directors 
and Stockholders of HollyFrontier Corporation 

We  have  audited  HollyFrontier  Corporation’s  internal  control  over  financial  reporting  as  of  December  31,  2011, 
based  on  criteria  established  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring 
Organizations  of  the  Treadway  Commission,  (the  “COSO  criteria”).    HollyFrontier  Corporation’s  management  is 
responsible  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its  assessment  of  the 
effectiveness of internal control over financial reporting included in the accompanying Management’s Report on its 
Assessment of the Company’s Internal Control over Financial Reporting.  Our responsibility is to express an opinion 
on the effectiveness of the Company’s internal control over financial reporting based on our audit. 

We  conducted  our  audit  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether  effective  internal  control  over  financial  reporting  was  maintained  in  all  material  respects.    Our  audit 
included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk  that  a  material 
weakness  exists,  testing  and  evaluating  the  design  and  operating  effectiveness  of  internal  control  based  on  the 
assessed risk, and performing such other procedures as we considered necessary in the circumstances.  We believe 
that our audit provides a reasonable basis for our opinion. 

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable  assurance 
regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in 
accordance  with  generally  accepted  accounting  principles.    A  company’s  internal  control  over  financial  reporting 
includes  those  policies  and  procedures  that  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable 
assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance 
with  generally  accepted  accounting  principles  and  that  receipts  and  expenditures  of  the  company  are  being  made 
only  in  accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (3)  provide  reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s 
assets that could have a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate. 

In  our  opinion,  HollyFrontier  Corporation  maintained,  in  all  material  respects,  effective  internal  control  over 
financial reporting as of December 31, 2011, based on the COSO criteria. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), the consolidated balance sheets of HollyFrontier Corporation as of December 31, 2011 and 2010, and the 
related consolidated statements of income, cash flows, equity and comprehensive income for each of the three years 
in the period ended December 31, 2011 and our report dated February 28, 2012 expressed an unqualified opinion 
thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

The Board of Directors 
and Stockholders of HollyFrontier Corporation 

We have audited the accompanying consolidated balance sheets of HollyFrontier Corporation (the “Company”) as 
of  December  31,  2011  and  2010,  and  the  related  consolidated  statements  of  income,  cash  flows,  equity  and 
comprehensive  income  for  each  of  the  three  years  in  the  period  ended  December  31,  2011.    These  financial 
statements  are  the  responsibility  of  the  Company’s  management.    Our  responsibility  is  to  express  an  opinion  on 
these financial statements based on our audits. 

We  conducted  our  audits  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether  the  financial  statements  are  free  of  material  misstatement.    An  audit  includes  examining,  on  a  test  basis, 
evidence supporting the amounts and disclosures in the financial statements.  An audit also includes assessing the 
accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall 
financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion. 

In  our  opinion,  the  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the  consolidated 
financial position of HollyFrontier Corporation at December 31, 2011 and 2010, and the consolidated results of its 
operations and its cash flows for each of the three years in the period ended December 31, 2011, in conformity with 
U.S. generally accepted accounting principles. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States),  HollyFrontier  Corporation’s  internal  control  over  financial  reporting  as  of  December  31,  2011,  based  on 
criteria  established  in  Internal  Control  –  Integrated  Framework  issued  by  the  Committee  of  Sponsoring 
Organizations  of  the  Treadway  Commission,  and  our  report  dated  February  28,  2012  expressed  an  unqualified 
opinion thereon.

HOLLYFRONTIER CORPORATION 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

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

Description of Business:  References herein to HollyFrontier Corporation (“HollyFrontier”) include HollyFrontier 
and  its  consolidated  subsidiaries.    In  accordance  with  the  Securities  and  Exchange  Commission’s  (“SEC”)  “Plain 
English”  guidelines,  this  Annual  Report  on  Form  10-K  has  been  written  in  the  first  person.    In  these  financial 
statements, the words “we,” “our,” “ours” and “us” refer only to HollyFrontier and its consolidated subsidiaries or to 
HollyFrontier or an individual subsidiary and not to any other person with certain exceptions.  Generally, the words 
“we,” “our,” “ours” and “us” include 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  merged  with  Frontier  Oil  Corporation  (“Frontier”)  effective  July  1,  2011.    Concurrent  with  the  merger,  we 
changed  our  name  from  Holly  Corporation  (“Holly”)  to  HollyFrontier  and  changed  the  ticker  symbol  for  our 
common  stock  traded  on  the  New  York  Stock  Exchange  to  “HFC”  (see  Note  2).    Accordingly,  these  financial 
statements  include  Frontier,  its  consolidated  subsidiaries  and  the  operations  of  the  merged  Frontier  businesses 
effective July 1, 2011, but not prior to this date.   

We are principally an independent petroleum refiner that produces high-value light products such as gasoline, diesel 
fuel, jet fuel, specialty lubricant products, and specialty and modified asphalt.  We own and operate five petroleum 
refineries that serve markets throughout the Mid-Continent, Southwest and Rocky Mountain regions of the United 
States.  As of December 31, 2011, we: 

• 

• 

• 

• 

• 

owned and operated a petroleum refinery in El Dorado, Kansas (the “El Dorado Refinery”), two refinery 
facilities  located  in  Tulsa,  Oklahoma  (collectively,  the  “Tulsa  Refineries”),  a  refinery  in  Artesia,  New 
Mexico that is operated in conjunction with crude oil distillation and vacuum distillation and other facilities 
situated 65 miles away in Lovington, New Mexico (collectively, the “Navajo Refinery”), a refinery located 
in  Cheyenne,  Wyoming  (the  “Cheyenne  Refinery”)  and  a  refinery  in  Woods  Cross,  Utah  (the  “Woods 
Cross Refinery”); 
owned  and  operated  NK  Asphalt  Partners  (“NK  Asphalt”)  which  operates  various  asphalt  terminals  in 
Arizona and New Mexico; 
owned  a  75%  interest  in  a  12-inch  refined  products  pipeline  from  Salt  Lake  City,  Utah  to  Las  Vegas, 
Nevada, together with terminal facilities in the Cedar City, Utah and North Las Vegas areas (the “UNEV 
Pipeline”); 
owned  Ethanol  Management  Company  (“EMC”),  a  products  terminal  and  blending  facility  near  Denver, 
Colorado and a 50% interest in Sabine Biofuels II, LLC (“Sabine Biofuels”), a biodiesel production facility 
located in Port Arthur, Texas; and 
owned  a  42%  interest  in  HEP,  a  consolidated  variable  interest  entity  (“VIE”),  which  includes  our  2% 
general partner interest.  HEP owns and operates logistic assets consisting of petroleum product and crude 
oil  pipelines  and  terminal,  tankage  and  loading  rack  facilities  that  principally  support  our  refining  and 
marketing  operations  in  the Mid-Continent,  Southwest  and  Rocky  Mountain regions of  the United States 
and Alon USA, Inc.’s (“Alon”) refinery in Big Spring, Texas.  Additionally, HEP owns a 25% interest in 
SLC Pipeline LLC (the “SLC Pipeline”), a 95-mile intrastate pipeline system that serves refineries in the 
Salt Lake City area. 

On  August  3,  2011,  our  Board  of  Directors  declared  a  two-for-one  stock  split,  payable  in  the  form  of  a  common 
stock dividend for each issued and outstanding share of our common stock.  The stock dividend was paid August 31, 
2011 to all shareholders of record on August 24, 2011.  We have retained the current par value of $0.01 per share for 
all shares of our common stock and have reclassified $763,000 (the amount equal to the par value of the additional 
stock  issued)  from  additional  capital  to  common  stock  to  reflect  this  stock  split  at  December  31,  2010.    All 
references  to  share  and  per  share  amounts  in  these  consolidated  financial  statements  and  related  disclosures  have 
been adjusted to reflect the effect of the stock split for all periods presented. 

-73-

 
 
 
 
 
 
 
 
Principles  of  Consolidation:    Our  consolidated  financial  statements  include  our  accounts  and  the  accounts  of 
partnerships and joint ventures that we control through a 50% or more ownership interest or through a controlling 
financial  interest  with  respect  to  variable  interest  entities.    All  significant  intercompany  transactions  and  balances 
have been eliminated.  

Variable Interest Entity:  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  or  a  controlling  interest  in  the 
entity, or have voting rights that are not proportionate to their economic interest.  As the general partner of HEP, we 
have  the  sole  ability  to  direct  the  activities  of  HEP  that  most  significantly  impact  HEP’s  economic  performance.  
Additionally,  since  our  obligation  to  absorb  losses  and  receive  benefits  from  HEP  are  significant  to  HEP,  we  are 
HEP’s primary  beneficiary  and  therefore, we  consolidate  HEP.   Our revaluation of HEP’s  assets  and  liabilities  at 
March 1, 2008 (date of reconsolidation) resulted in basis adjustments to our consolidated HEP balances.  Therefore, 
our reported amounts for HEP may not agree to amounts reported in HEP’s periodic public filings. 

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. 

Marketable Securities:  We consider all marketable debt securities with maturities greater than three months at the 
date  of  purchase  to  be  marketable  securities.    Our  marketable  securities  are  primarily  issued  by  government  and 
municipal entities with the maximum maturity or put date of any individual issue not more than two years, while the 
maximum duration of the portfolio of investments is not greater than one year.  These instruments are classified as 
available-for-sale,  and  as  a  result,  are  reported  at  fair  value.    Unrealized  gains  and  losses,  net  of  related  income 
taxes, are reported as a component of accumulated other comprehensive income. 

Accounts Receivable:  The majority of our accounts receivable are due from companies in the petroleum industry.  
Credit is extended based on 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 current sales levels as 
well as specific accounts identified as high risk, which historically have been minimal.   Credit losses are charged to 
the allowance for doubtful accounts when an account is deemed uncollectible.  Our allowance for doubtful accounts 
was $3.5 million and $2.1 million at December 31, 2011 and 2010, respectively.   

Accounts  receivable  attributable  to  crude  oil  resales  generally  represent  the  sell  side  of  excess  crude  oil  sales  to 
other purchasers and / or users in cases when our crude oil supplies are in excess of our immediate needs as well as 
certain reciprocal buy /sell exchanges of crude oil.  At times we enter into such buy / sell exchanges to facilitate the 
delivery of quantities  to  certain  locations.   In  many  cases,  we  enter  into  net  settlement  agreements  relating  to  the 
buy/sell arrangements, which may mitigate credit risk. 

Inventories:  Inventories are stated at the lower of cost, using the last-in, first-out (“LIFO”) method for crude oil 
unfinished and finished refined products and the average cost method for materials and supplies, or market.  Cost, 
consisting of raw material, transportation and conversion costs,  is determined using the LIFO inventory valuation 
methodology  and  market  is  determined using  current  estimated  selling prices.    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.

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,  Derivative  Instruments  and  Hedging 
Activities, for additional information. 

Long-lived assets:  We calculate depreciation and amortization based on estimated useful lives and salvage values 
of  our  assets.    We  evaluate  long-lived  assets  for  potential  impairment  by  identifying  whether  indicators  of 
impairment  exist  and,  if  so,  assessing  whether  the  long-lived  assets  are  recoverable  from  estimated  future 
undiscounted cash flows.  The actual amount of impairment loss, if any, to be recorded is equal to the amount by 
which a long-lived asset’s carrying value exceeds its fair value.  No impairments of long-lived assets were recorded 
during the years ended December 31, 2011, 2010 and 2009. 

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. 

At December 31, 2011, we have an asset retirement obligations of $14.4 million, which are included in “Other long-
term  liabilities”  in  our  consolidated  balance  sheets.    We  acquired  asset  retirement  obligations  of  $6.2  million  in 
connection  with  our  “merger  of  equals”  with  Frontier  on  July  1,  2011  and  $5.8  million  with  our  Tulsa  refinery 
facility acquisitions in 2009 (see Note 2).  Accretion expense was insignificant for the years ended December 31, 
2011, 2010 and 2009.  

Intangibles  and  Goodwill:    Intangible  assets  are  assets  (other  than  financial  assets)  that  lack  physical  substance.  
Goodwill  represents  the  excess  of  the  cost  of  an  acquired  entity  over  the  fair  value  of  the  assets  acquired  less 
liabilities assumed.  Goodwill acquired in a business combination and intangible assets with indefinite useful lives 
are not amortized while, intangible assets with finite useful lives are amortized on a straight-line basis.  Goodwill 
and intangible assets not subject to amortization are tested for impairment annually or more frequently if events or 
changes in circumstances indicate the asset might be impaired.   

In  addition  to  goodwill,  our  consolidated  HEP  assets  include  a  third-party  transportation  agreement  that  currently 
generates minimum annual cash inflows of $23.4 million and has an expected remaining term through 2035.  The 
transportation agreement is being amortized on a straight-line basis through 2035 that results in annual amortization 
expense of $2 million.  At December 31, 2011, the balance of this transportation agreement was $46.5 million, net 
of  accumulated  amortization  of  $13.7  million,  which  is  included  in  “Intangibles  and  other”  in  our  consolidated 
balance sheets.  There were no impairments of intangible assets or goodwill during the years ended December 31, 
2011, 2010 and 2009. 

Investments in Joint Ventures:  We consolidate the financial and operating results of joint ventures in which we 
have an ownership interest of greater than 50% and use the equity method of accounting for investments in which 
we have a 50% or less ownership interest.  Under the equity method of accounting, we record our pro-rata share of 
earnings, and contributions to and distributions from joint ventures as adjustments to our investment balance. 

HEP  has  a  25%  joint  venture  interest  in  the  SLC  Pipeline  that  is  accounted  for  using  the  equity  method  of 
accounting.  As of December 31, 2011, HEP’s underlying equity in the SLC Pipeline was $60.9 million compared to 
its recorded investment balance of $25.3 million, a difference of $35.6 million.  This is attributable to the difference 
between  HEP’s  contributed  capital  and  its  allocated  equity  at  formation  of  the  SLC  Pipeline.    This  difference  is 
being amortized as an adjustment to HEP’s pro-rata share of earnings.    

Revenue  Recognition:    Refined  product  sales  and  related  cost of  sales are  recognized  when products  are  shipped 
and title has passed to customers.  HEP recognizes pipeline transportation revenues as products are shipped through 

-75-

 
 
 
 
 
 
 
 
 
 
 
its pipelines.  All revenues are reported inclusive of shipping and handling costs billed and exclusive of any taxes 
billed to customers.  Shipping and handling costs incurred are reported in cost of products sold. 

Depreciation:    Depreciation  is  provided  by  the  straight-line  method  over  the  estimated  useful  lives  of  the  assets, 
primarily 20 to 25 years for refining, pipeline and terminal facilities, 10 to 40 years for buildings and improvements, 
5 to 30 years for other fixed assets and 5 years for vehicles. 

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 carryover cost.  Operating expenses include direct costs 
of labor, maintenance materials and services, utilities, marketing expense and other direct operating costs.  General 
and administrative expenses include compensation, professional services and other support costs. 

Deferred  Maintenance  Costs:    Our  refinery  units  require  regular  major  maintenance  and  repairs  which  are 
commonly referred to as “turnarounds.”  Catalysts used in certain refinery processes also require regular “change-
outs.”  The required frequency of the maintenance varies by unit and by catalyst, but generally is every two to five 
years.    Turnaround  costs  are  deferred  and  amortized  over  the  period  until  the  next  scheduled  turnaround.    Other 
repairs and maintenance costs are expensed when incurred. 

Environmental Costs:  Environmental costs are charged to operating expenses if they relate to an existing condition 
caused  by  past  operations  and  do  not  contribute  to  current  or  future  revenue  generation.    Liabilities  are  recorded 
when site restoration and environmental remediation, cleanup and other obligations are either known or considered 
probable and can be reasonably estimated.   Such estimates require judgment with respect to costs, timeframe and 
extent  of  required  remedial  and  clean-up  activities  and  are  subject  to  periodic  adjustments  based  on  currently 
available information.  Recoveries of environmental costs through insurance, indemnification arrangements or other 
sources are included in other assets to the extent such recoveries are considered probable.  

Contingencies:  We are subject to proceedings, lawsuits and other claims related to environmental, labor, product 
and other matters.  We are required to assess the likelihood of any adverse judgments or outcomes to these matters 
as well as potential ranges of probable losses.  A determination of the amount of reserves required, if any, for these 
contingencies is made after careful analysis of each individual issue.  The required reserves may change in the future 
due to new developments in each matter or changes in approach such as a change in settlement strategy in dealing 
with these matters. 

Income Taxes:  Provisions for income taxes include deferred taxes resulting from temporary differences in income 
for  financial  and  tax  purposes,  using  the  liability  method  of  accounting  for  income  taxes.    The  liability  method 
requires the effect of tax rate changes on current and accumulated deferred income taxes to be reflected in the period 
in which the rate change was enacted.  The liability method also requires that deferred tax assets be reduced by a 
valuation allowance unless it is more likely than not that the assets will be realized. 

Potential interest and penalties related to income tax matters are recognized in income tax expense.  We believe we 
have appropriate support for the income tax positions taken and to be taken on our income tax returns and that our 
accruals for  tax  liabilities  are  adequate for  all  open  years  based on  an  assessment  of many  factors, including  past 
experience and interpretations of tax law applied to the facts of each matter. 

New Accounting Pronouncements 

Presentation of Comprehensive Income 
In  June  2011,  an  accounting  standard  update  was  issued  that  requires  the  presentation  of  net  income  and  other 
comprehensive income in one continuous statement or in two separate, but consecutive, statements and eliminates 
the option to present the components of other comprehensive income in the statement of stockholders’ equity.  This 
standard is effective January 1, 2012 and will be applied retrospectively.  This standard will not have an impact on 
our financial condition, results of operations and cash flows.

Intangibles — Goodwill and Other: Testing Goodwill for Impairment 
In September 2011, an accounting standard update was issued that allows entities an option to first assess qualitative 
factors  to  determine  whether  it  is  necessary  to  perform  the  two-step  quantitative  goodwill  impairment  test.    This 
standard is effective for annual and interim goodwill impairment testing beginning January 1, 2012.  This standard 
will not have an impact on our financial condition, results of operations and cash flows. 

NOTE 2:  Merger and Acquisitions 

Holly - Frontier Merger 

On February 21, 2011, we entered into a merger agreement providing for a “merger of equals” business combination 
between  us  and  Frontier  for  purposes  of  creating  a  more  diversified  company  having  a  broader  geographic  sales 
footprint, stronger financial position and to create a more efficient corporate overhead structure, while also realizing 
synergies and promoting accretion to earnings per share. The legacy Frontier business operations consist of crude oil 
refining  and  the  wholesale  marketing  of  refined  petroleum  products  produced  at  the  El  Dorado  and  Cheyenne 
Refineries  and  serve  markets  in  the  Rocky  Mountain  and  Plains  States  regions  of  the  United  States.    On  July  1, 
2011,  North  Acquisition,  Inc.,  a  direct  wholly-owned  subsidiary  of  Holly,  merged  with  and  into  Frontier,  with 
Frontier surviving as a wholly-owned subsidiary of Holly.  Concurrent with the merger, we changed our name to 
HollyFrontier  Corporation  and  changed  the  ticker  symbol  for  our  common  stock  traded  on  the  New  York  Stock 
Exchange  to  “HFC.”    Subsequent  to  the  merger  and  following  approval  by  the  post-closing  board  of  directors  of 
HollyFrontier,  Frontier  merged  with  and  into  HollyFrontier,  with  HollyFrontier  continuing  as  the  surviving 
corporation. 

In  accordance  with  the  merger  agreement,  we  issued  102.8  million  shares  of  HollyFrontier  common  stock  in 
exchange for outstanding shares of Frontier common stock to former Frontier stockholders.  Each outstanding share 
of  Frontier  common  stock  was  converted  into  0.4811  shares  of  HollyFrontier  common  stock  with  any  fractional 
shares paid in cash.  The aggregate consideration paid in stock in connection with the merger was $3.7 billion.  This 
is  based  on  our  July  1,  2011  market  closing  price  of  $35.93  and  includes  a  portion  of  the  fair  value  of  the 
outstanding equity-based awards assumed from Frontier that relates to pre-merger services.  The number of shares 
issued  in  connection  with  our  merger  with  Frontier  and  the  closing  market  price  of  our  common  stock  at  July  1, 
2011 have been adjusted to reflect the two-for-one stock split on August 31, 2011.   

The  merger  has  been  accounted  for  using  the  acquisition  method  of  accounting  with  Holly  being  considered  the 
acquirer  of  Frontier  for  accounting  purposes.  Therefore,  the  purchase  price  was  allocated  to  the  fair  value  of  the 
acquired  assets  and  assumed  liabilities  at  the  acquisition  date,  with  the  excess  purchase  price  being  recorded  as 
goodwill. The goodwill resulting from the merger is primarily due to the favorable location of the acquired refining 
facilities and the expected synergies to be gained from our combined business operations. Goodwill related to this 
merger is not deductible for income tax purposes. 

The following table summarizes our fair value estimates of the Frontier assets and liabilities recognized upon our 
merger on July 1, 2011:

Our valuations of the acquired Frontier assets and liabilities are not final as of December 31, 2011. These fair value 
estimates, including the value of goodwill and the allocation thereof to our reporting units, are preliminary in nature 
and therefore, may change upon the completion of such valuations. 

Beginning  July  1,  2011,  HollyFrontier’s  consolidated  financial  and  operating  results  reflect  the  operations  of  the 
merged  Frontier  businesses.    Our  consolidated  statements  of  income  include  revenues  and  income  before  income 
taxes of $4,183.8 million and $575.8 million, respectively, for the period from July 1, 2011 through December 31, 
2011 that are attributable to the operations of the legacy Frontier refineries.   

Assuming  the  merger  had  been  consummated  on  January 1,  2010,  pro  forma  revenues,  net  income  and  basic  and 
diluted earnings per share are as follows: 

Years Ended December 31,

The  pro  forma  financial  information  above  reflects  our  fair  value  estimates  of  the  acquired  Frontier  assets  and 
liabilities.    Adjustments  made  to  derive  pro  forma  net  income  primarily  relate  to  depreciation  and  amortization 
expense in order to reflect our new basis in the acquired legacy Frontier refining facilities.   

As  of  December  31,  2011,  we  have  recognized  $15.1  million  in  merger  transaction  costs  that  are  presented 
separately in our income statements and primarily relate to legal, advisory and other professional fees incurred since 
the  announcement  of  our  merger  agreement  in  February  2011.    This  does  not  include  costs  to  integrate  the 
operations of the combined company.  For the year ended December 31, 2011, general and administrative expenses 
include $26.5 million in integration and severance costs associated with the merger integration. 

Tulsa Refinery Acquisitions 

On June 1, 2009, we acquired an 85,000 BPSD refinery located in Tulsa, Oklahoma (the “Tulsa West facility”) from 
Sunoco for $157.8 million in cash, including crude oil, refined product and other inventories valued at $92.8 million.  
In October 2009, we sold to an affiliate of Plains All American Pipeline, L.P. (“Plains”) a portion of the crude oil 
petroleum storage, and certain refining-related crude oil receiving pipeline facilities that were acquired as part of the 
refinery  assets.    Due  to  our  continuing  involvement  in  these  assets,  this  transaction  has  been  accounted  for  as  a 
financing transaction (see Note 13). 

On December 1, 2009, we acquired a 75,000 BPSD refinery from an affiliate of Sinclair Oil Company (“Sinclair”) 
also located in Tulsa, Oklahoma (the “Tulsa East facility”) for $183.3 million, including crude oil, refined product 
and  other  inventories  valued  at  $46.4  million.    The  total  purchase  price  consisted  of  $109.3  million  in  cash  and 
2,789,155  shares  of  our  common  stock  having  a  value  of  $74  million.    We  operate  the  Tulsa  Refineries  in  an 
integrated manner, with both complexes having a combined crude processing rate of 125,000 BPSD.   

In  accounting  for  the  Tulsa  acquisitions,  we  recorded  $20.6  million  in  materials  and  supplies,  $139.2  million  in 
crude  oil  and  refined  products  inventory,  $203.8  million  in  properties,  plants  and  equipment,  $8.2  million  in 
prepayments  and  other,  $6.3  million  in  accrued  liabilities  and  $24.4  million  in  other  long-term  liabilities.    The 
acquired  liabilities  primarily  relate  to  environmental  and  asset  retirement  obligations.    Additionally,  we  incurred 
$3.1 million in costs directly related to these acquisitions that were expensed as acquisition costs in 2009.  

NOTE 3:  Holly Energy Partners 

HEP, a consolidated VIE, is a publicly held master limited partnership that was formed to acquire, own and operate 
the  petroleum  product  and  crude  oil  pipeline  and  terminal,  tankage  and  loading  rack  facilities  that  support  our 
refining  and  marketing  operations  in  the  Mid-Continent,  Southwest  and  Rocky  Mountain  regions  of  the  United 

-78-

 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
States.  HEP also owns and operates refined product pipelines and terminals, located primarily in Texas, that serve 
Alon USA, Inc.’s (“Alon”) refinery in Big Spring, Texas. 

As of December 31, 2011, we owned a 42% interest in HEP, including the 2% general partner interest.  We are the 
primary  beneficiary  of  HEP’s  earnings  and  cash  flows  and  therefore  we  consolidate  HEP.    See  Note  22  for 
supplemental guarantor/non-guarantor financial information, including HEP balances included in these consolidated 
financial  statements.    All  intercompany  transactions  with  HEP  are  eliminated  in  our  consolidated  financial 
statements. 

HEP has two primary customers (including us) and generates revenues by charging tariffs for transporting petroleum 
products  and  crude  oil  though  its  pipelines,  by  charging  fees  for  terminalling  refined  products  and  other 
hydrocarbons,  and  storing  and  providing  other  services  at  its  storage  tanks  and  terminals.    Under  our  long-term 
transportation agreements with HEP (discussed further below), we represented 78% of HEP’s total revenues for the 
year ended December 31, 2011.  We do not provide financial or equity support through any liquidity arrangements 
and /or guarantees to HEP. 

HEP  has  outstanding  debt  under  a  senior  secured  revolving  credit  agreement  and  its  senior  notes.    With  the 
exception of the assets of HEP Logistics Holdings, L.P., one of our wholly-owned subsidiaries and HEP’s general 
partner, HEP’s creditors have no recourse to our assets.  Any recourse to HEP’s general partner would be limited to 
the  extent  of  HEP  Logistics  Holdings,  L.P.’s  assets,  which  other  than  its  investment  in  HEP,  are  not  significant.  
Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries.  See Note 13 for 
a description of HEP’s debt obligations.    

At December 31, 2011, we have an agreement to pledge up to 6,000,000 of our HEP common units to collateralize 
certain crude oil purchases.  These units represent a 21% ownership interest in HEP. 

HEP has risk associated with its operations.  If a major shipper of HEP were to terminate its contracts or fail to meet 
desired shipping or throughput levels for an extended period 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. 

2011 Acquisition 

Legacy Frontier Tankage and Terminal Asset Transaction 
On November 9, 2011, HEP acquired from us certain tankage, loading rack and crude receiving assets located at our 
El Dorado and Cheyenne Refineries.  We received non-cash consideration consisting of promissory notes with an 
aggregate principal amount of $150 million and 3,807,615 HEP common units.  

Since  HEP  is  a  consolidated  VIE,  our  transactions  with  HEP  including  fees  paid  under  our  transportation 
agreements with HEP are eliminated and have no impact on our consolidated financial statements.  

2010 Acquisitions 

Tulsa East / Lovington Storage Asset Transaction 
On March 31, 2010, HEP acquired from us certain storage assets for $93 million, consisting of hydrocarbon storage 
tanks  having  approximately  2  million  barrels  of  storage  capacity,  a  rail  loading  rack  and  a  truck  unloading  rack 
located at our Tulsa East facility and an asphalt loading rack facility located at our Navajo Refinery facility located 
in Lovington, New Mexico. 

2009 Acquisitions 

Sinclair Logistics and Storage Assets Transaction 
On December 1, 2009, HEP acquired from Sinclair storage tanks having approximately 1.4 million barrels of storage 
capacity and loading racks at what is now our Tulsa East facility for $79.2 million.  The purchase price consisted of

$25.7 million in cash, including $4.2 million in taxes and 1,373,609 of HEP’s common units having a fair value of 
$53.5 million.   

Roadrunner / Beeson Pipelines Transaction 
Also on December 1, 2009, HEP acquired our two newly constructed pipelines for $46.5 million, consisting of a 65-
mile, 16-inch crude oil pipeline (the “Roadrunner Pipeline”) that connects our Navajo Refinery Lovington facility to 
a terminus of Centurion Pipeline L.P.’s pipeline extending between west Texas and Cushing, Oklahoma and a 37-
mile, 8-inch crude oil pipeline that connects HEP’s New Mexico crude oil gathering system to our Navajo Refinery 
Lovington facility (the “Beeson Pipeline”). 

Tulsa West Loading Racks Transaction 
On August 1, 2009, HEP acquired from us, certain truck and rail loading/unloading facilities located at our Tulsa 
West facility for $17.5 million.  The racks load refined products and lube oils produced at the Tulsa West facility 
onto rail cars and/or tanker trucks.   

Lovington-Artesia Pipeline Transaction 
On June 1, 2009, HEP acquired our newly constructed, 16-inch intermediate pipeline for $34.2 million that runs 65 
miles  from  our  Navajo  Refinery’s  crude  oil  distillation  and  vacuum  facilities  in  Lovington,  New  Mexico  to  its 
petroleum refinery located in Artesia, New Mexico.   

SLC Pipeline Joint Venture Interest 
On March 1, 2009, HEP acquired a 25% joint venture interest in the SLC Pipeline, a new 95-mile intrastate pipeline 
system  jointly  owned  with  Plains.    The  SLC  Pipeline  commenced  operations  effective  March  2009  and  allows 
various  refineries  in  the  Salt  Lake  City  area,  including  our  Woods  Cross  Refinery,  to  ship  crude  oil  into  the  Salt 
Lake City area from the Utah terminus of the Frontier Pipeline as well as crude oil flowing from Wyoming and Utah 
via Plains’ Rocky Mountain Pipeline.  HEP’s capitalized joint venture contribution was $25.5 million.  

Rio Grande Pipeline Sale 
On December 1, 2009, HEP sold its 70% interest in Rio Grande Pipeline Company (“Rio Grande”) to a subsidiary of 
Enterprise Products Partners LP for $35 million.  Results of operations of Rio Grande are presented in discontinued 
operations.  

In accounting for this sale, HEP recorded a gain of $14.5 million and a receivable of $2.2 million representing its 
final distribution from Rio Grande.  The recorded net asset balance of Rio Grande at December 1, 2009, was $22.7 
million,  consisting  of  cash  of  $3.1  million,  $29.9  million  in  properties  and  equipment,  net  and  $10.3  million  in 
equity, representing BP, Plc’s 30% noncontrolling interest.

Transportation Agreements 

HEP  serves  our  refineries  under  long-term  pipeline  and  terminal,  tankage  and  throughput  agreements  expiring  in 
2019 through 2026.  Under these agreements, we pay HEP fees to transport, store and throughput volumes of refined 
product  and  crude oil  on  HEP’s  pipeline  and  terminal,  tankage  and  loading  rack  facilities  that  result  in  minimum 
annual  payments  to  HEP.    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 

-80-

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Regulatory  Commission  (“FERC”)  index.  As  of  December  31,  2011,  these  agreements  result  in  minimum 
annualized payments to HEP of $192 million. 

HEP Common Unit Issuances 

2011 Issuances 
In December 2011, HEP issued 1,475,000 of its common units priced at $53.50 per unit.  Aggregate net proceeds of 
$75.8 million were used to repay a portion of the $150 million in promissory notes issued to us in connection with 
HEP’s November 9, 2011 asset acquisition from us.  This repayment to us is eliminated in our consolidated financial 
statements. 

In November 2011, HEP issued 3,807,615 of its common units to us as partial consideration for its purchase from us 
of certain tankage, loading rack and crude receiving assets located at our El Dorado and Cheyenne Refineries.    

As a result of these 2011 HEP common unit issuances, we adjusted additional capital, other comprehensive income 
and equity attributable to HEP’s noncontrolling interest holders to effectively reallocate a portion of HEP’s equity 
among its unitholders. Additionally, we recorded a reduction of $80.7 million to additional capital that relates to a 
deferred  tax  liability  that  was  recorded  as  a  result  of  the  goodwill  transferred  to  HEP  upon  its  acquisition  of  our 
tankage and terminal assets in November 2011. 

2009 Issuances 
In December 2009, HEP issued 1,373,609 of its common units having a value of $53.5 million to Sinclair as partial 
consideration of its purchase of Sinclair’s Tulsa logistics assets.  

In November 2009, HEP issued 2,185,000 of its common units priced at $35.78 per unit. Aggregate net proceeds of 
$74.9  million  were  used  to  fund  the  cash  portion  of  HEP’s  December  1,  2009  asset  acquisitions,  to  repay 
outstanding borrowings under HEP’s credit agreement and for general partnership purposes.   

Additionally in May 2009, HEP issued 2,192,400 of its common units priced at $27.80 per unit.  Net proceeds of 
$58.4 million were used to repay outstanding borrowings under HEP’s credit agreement and for general partnership 
purposes.  

Note 4: Financial Instruments 

Our  financial  instruments  consist  of  cash  and  cash  equivalents,  investments  in  marketable  securities,  accounts 
receivable, accounts payable, debt and derivative instruments.  The carrying amounts of cash and cash equivalents, 
accounts receivable and accounts payable approximate fair value due to the short-term maturity of these instruments.   
Debt  consists of  outstanding  principal under HEP’s revolving  credit  agreement  (which  approximates  fair  value  as 
interest rates are reset frequently at current interest rates) and senior notes. 

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

• 

• 

• 

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

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

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

The  carrying  amounts  and  related  estimated  fair  values  of  our  investments  in  marketable  securities,  derivative 
instruments and the senior notes at December 31, 2011 and December 31, 2010 are as follows:

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

Level 2 Financial Instruments 
Investments  in  marketable  debt  securities  and  derivative  instruments  consisting  of  commodity  price  swaps  and 
HEP’s  interest  rate  swap  are  measured  and  recorded  at  fair  value  using  Level  2  inputs.    With  respect  to  the 
commodity price and interest rate swap contracts, fair value 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 inputs, quoted forward commodity prices with respect to our commodity 
price swaps and the forward London Interbank Offered Rate (“LIBOR”) yield curve with respect to HEP’s interest 
rate swap.  The fair value of the marketable debt securities and senior notes is based on values provided by a third-
party bank, which were derived using market quotes for similar type instruments, a Level 2 input.  

Level 3 Financial Instruments 
During  2011,  we  entered  into  certain  commodity  price  swap  contracts  related  to  forecasted  sales  of  14,640,000 
barrels  of  diesel  and  unleaded  gasoline  for  which  quoted  forward  market  prices  are  not  readily  available.    The 
forward rate used to value these price swaps was derived using a projected forward rate using quoted market rates 
for similar products, adjusted for regional pricing differentials, a Level 3 input.  At December 31, 2011, we had a 
pre-tax  unrealized  gain  in  accumulated  other  comprehensive  income  related  to  these  contracts.    Our  Level  3 
commodity price swaps had no effect on earnings during the year ended December 31, 2011. 

NOTE 5:  Earnings Per Share 

Basic earnings per share from continuing operations is calculated as income from continuing operations divided by 
the average number of shares of common stock outstanding.  Diluted earnings per share assumes, when dilutive, the 
issuance of the net incremental shares from stock options, variable restricted shares and variable performance shares.  
The average number of shares of common stock and per share amounts have been adjusted to reflect the two-for-one 
stock split effective August 31, 2011. The following is a reconciliation of the denominators of the basic and diluted 
per share computations for income from continuing operations:

NOTE 6: 

Stock-Based Compensation 

As of December 31, 2011, we have two principal share-based compensation plans including the Frontier plan that 
was retained upon the July 1, 2011 merger (the “Long-Term Incentive Compensation Plan”).  All outstanding and 
unvested  restricted  stock  and  performance  share  grants  under  the  legacy  Frontier  plan  were  converted  into 
equivalent HollyFrontier units based on the July 1, 2011 common stock conversion ratio of 0.4811.  A portion of the 
fair value of these awards (based on our July 1, 2011 closing stock price of $35.93) relative to the remaining vesting 
period of the awards will be expensed over the remaining terms of these grants. 

The compensation cost charged against income for these plans was $24.7 million, $9.3 million and $6.8 million for 
the years ended December 31, 2011, 2010 and 2009, respectively.  The total income tax benefit recognized in the 
statements of income for share-based compensation arrangements was $9.6 million, $3.6 million and $2.6 million 
for the years ended December 31, 2011, 2010 and 2009, respectively.  Our current accounting policy for recognizing 
compensation  expense  for  awards  with  pro-rata  vesting  (substantially  all  of  our  awards)  is  to  expense  the  costs 
ratably over the vesting periods.  At December 31, 2011, 8,430,045 shares of common stock were reserved for future 
grants  under  the  current  Long-Term  Incentive  Compensation  Plan,  which  allows  for  awards  of  common  stock, 
options, restricted stock, or other performance awards. 

Additionally, HEP maintains share-based compensation plans for HEP directors and select Holly Logistic Services, 
L.L.C. executives and employees.  Compensation cost attributable to HEP’s share-based compensation plans for the 
years ended December 31, 2011, 2010 and 2009 was $2.1 million, $2.2 million and $1.2 million, respectively. 

Restricted Stock 
Under  our  Long-Term  Incentive  Compensation  Plan,  we  grant  certain  officers,  other  key  employees  and  non-
employee  directors restricted  stock  awards with  substantially  all  awards vesting  generally  over  a period  of one  to 
five years.  Although ownership of the shares does not transfer to the recipients until after the shares vest, recipients 
generally  have  dividend  rights  on  these  shares  from  the  date  of  grant.    The  vesting  for  certain  key  executives  is 
contingent upon certain performance targets being realized.  The fair value of each share of restricted stock awarded, 
including the shares issued to the key executives, is measured based on the market price as of the date of grant and is 
amortized over the respective vesting period.   

A summary of restricted stock activity and changes during the year ended December 31, 2011 is presented below:

(1)  Includes  425,554  non-vested  restricted  stock  grants  under  the  legacy  Frontier  plan  that  were  outstanding  and  retained  by 

HollyFrontier at July 1, 2011. 

The  total  fair  value  of  restricted  stock  vested  and  transferred  to  recipients  during  the  years  ended  December  31, 
2011, 2010 and 2009 was $9.1 million, $4.2 million and $3.4 million, respectively.  As of December 31, 2011, there 
was $13.9 million of total unrecognized compensation cost related to non-vested restricted stock grants.  That cost is 
expected to be recognized over a weighted-average period of 1.2 years.  

Performance Share Units 
Under our Long-Term Incentive Compensation Plan, we grant certain officers and other key employees performance 
share units, which are payable in stock upon meeting certain criteria over the service period, and generally vest over 
a period of one to three years.  Under the terms of our performance share unit grants, awards are subject to either a 
“financial performance” or “market performance” criteria.

During the year ended December 31, 2011, we granted 354,660 performance share units having a fair value based on 
our grant date closing stock price of $28.79.  These units are payable in stock and are subject to certain financial 
performance criteria.  The fair value of these performance share unit awards is based on the grant date closing stock 
price  of  each  respective  award  grant  and  will  apply  to  the  number  of  units  ultimately  awarded.    The  number  of 
shares  ultimately  issued  for  each  award  will  be  based  on  our  financial  performance  as  compared  to  peer  group 
companies  over  the  performance  period  and  can  range  from  zero  to  200%.    As  of  December  31,  2011,  estimated 
share payouts for outstanding non-vested performance share unit awards ranged from 150% to 195%. 

For  the  legacy  Frontier  performance  share  units  assumed  at  July  1,  2011,  performance  is  based  on  market 
performance  criteria,  which  is  calculated  as  the  total  shareholder  return  achieved  by  HollyFrontier  stockholders 
compared with the average shareholder return achieved by an equally-weighted peer group of independent refining 
companies over a three-year period.  These share unit awards are payable in stock based on share price performance 
relative to the defined peer group and can range from zero to 125% of the initial target award.  These performance 
share units  were  valued  at  July  1,  2011 using  a  Monte  Carlo valuation model,  which simulates  future  stock price 
movements  using  key  inputs  including  grant  date  and  measurement  date  stock  prices,  expected  stock  price 
performance, expected rate of return and volatility of our stock price relative to the peer group over the three-year 
performance  period.    The  fair  value  of  these  performance  share  units  at  July  1,  2011  was  $8.6  million.    Of  this 
amount,  $7.3  million  relates  to  post-merger  services  and  will  be  recognized  ratably  over  the  remaining  service 
period through 2013. 

A summary of performance share unit activity and changes during the year ended December 31, 2011 is presented 
below:

For the year ended December 31, 2011 we issued 178,148 shares of our common stock having a fair value of $2.6 
million related to vested performance share units.  Based on the weighted average grant date fair value of $20.71 
there  was  $11.7  million  of  total  unrecognized  compensation  cost  related  to  non-vested  performance  share  units.  
That cost is expected to be recognized over a weighted-average period of 1.1 years. 

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

Our  investment  portfolio  at  December  31,  2011  consisted  of  cash,  cash  equivalents  and  investments  in  debt 
securities primarily issued by government and municipal entities.  We also hold 1,000,000 shares of Connacher Oil 
and Gas Limited common stock that was received as partial consideration upon the sale of our Montana refinery in 
2006. 

We  invest  in  highly-rated  marketable  debt  securities,  primarily  issued  by  government  and  municipal  entities  that 
have  maturities  at  the  date  of  purchase  of  greater  than  three  months.    We  also  invest  in  other  marketable  debt 
securities with the maximum maturity or put date of any individual issue generally not greater than two years from 
the date of purchase.  All of these instruments, including investments in equity securities, are classified as available-
for-sale.    As  a  result,  they  are  reported  at  fair  value  using  quoted  market  prices.    Interest  income  is  recorded  as 
earned.  Unrealized gains and losses, net of related income taxes, are reported as a component of accumulated other 
comprehensive  income.    Upon  sale,  realized  gains  and  losses  on  the  sale  of  marketable  securities  are  computed 
based on the specific identification of the underlying cost of the securities sold and the unrealized gains and losses 
previously reported in other comprehensive income are reclassified to current earnings.

have been no impairments to our goodwill balances. 

NOTE 11:  UNEV Pipeline Joint Venture 

We own a 75% joint venture interest in the recently completed UNEV Pipeline, a 400 mile 12-inch refined products 
pipeline from Salt Lake City, Utah to Las Vegas, Nevada, together with terminal and ethanol blending facilities in 
the Cedar City, Utah and North Las Vegas areas and storage facilities at the Cedar City terminal with Sinclair, our 
joint  venture  partner,  owning  the  remaining  25%  interest.    The  pipeline  has  a  capacity  of  62,000  BPD  (based  on 
gasoline  equivalents),  and  has  the  capacity  for  further  expansion  to  120,000  BPD.    The  cost  of  constructing  this 
pipeline including terminals and ethanol blending and storage facilities was approximately $410 million, which is 
included  under  “Properties,  plants  and  equipment”  in  our  consolidated  balance  sheets.    The  pipeline  was 
mechanically complete in November 2011 and initial start-up activities commenced in December 2011.  We have an 
option  agreement  with  HEP  granting  them  an  option  to  purchase  all  of  our  equity  interests  in  this  joint  venture 
pipeline at a purchase price equal to our investment in this joint venture pipeline plus interest at 7% per annum.   

NOTE 12:  Environmental Costs 

Consistent with our accounting policy for environmental remediation costs, we expensed $14 million, ($0.6) million 
and  $4.2  million  for  the  years  ended  December  31,  2011,  2010  and  2009,  respectively,  for  environmental 
remediation obligations.  The accrued environmental liability reflected in the consolidated balance sheets was $42.2 
million and $26.2 million at December 31, 2011 and 2010, respectively, of which $31.7 million and $20.4 million, 
respectively,  was  classified  as  other  long-term  liabilities.  These  amounts  include  $7.3  million  in  environmental 
liabilities  that  we  assumed  in  connection  with  our  merger  with  Frontier  in  July  2011.    Future  expenditures  for 
environmental remediation that are expected to be incurred over the next several years are not discounted to their 
present value.  

NOTE 13:  Debt 

HollyFrontier Credit Agreement 
On  July  1,  2011,  we  entered  into  a  $1  billion  senior  secured  credit  agreement  (the  “HollyFrontier  Credit 
Agreement”)  with  Union  Bank,  N.A.  as  administrative  agent  and  BNP  Paribas  as  syndication  agent,  and  certain 
lenders from time to time party thereto, and terminated our previous $400 million credit agreement.  Additionally, 
Frontier terminated its previous $500 million credit agreement. The HollyFrontier Credit Agreement matures in July 
2016 and may be used to fund working capital requirements, capital expenditures, acquisitions and general corporate 
purposes.  Obligations  under  the  HollyFrontier  Credit  Agreement  are  collateralized  by  our  inventory,  accounts 
receivables and certain deposit accounts and guaranteed by our material, wholly-owned subsidiaries.   

We were in compliance with all covenants at December 31, 2011.  At December 31, 2011, we had no outstanding 
borrowings and outstanding letters of credit totaling $6.1 million under the HollyFrontier Credit Agreement.  At that 
level of usage, the unused commitment was $993.9 million at December 31, 2011.

HEP Credit Agreement 
At December 31, 2011, HEP had a $275 million senior secured revolving credit facility expiring in February 2016 
(the “HEP Credit Agreement”) with an outstanding balance of $200 million.  On February 3, 2012, the HEP Credit 
Agreement  was  amended,  increasing  the  size  of  the  credit  facility  from  $275  million  to  $375  million  (the  “HEP 
Amended Credit Agreement”) and is available to fund capital expenditures, investments, acquisitions, distribution 
payments and working capital and for general partnership purposes.  It is also available to fund letters of credit up to 
a $50 million sub-limit and to fund distributions to unitholders up to a $30 million sub-limit.  The HEP Amended 
Credit Agreement expires in February 2016; however, in the event that the 6.25% HEP senior notes (discussed later) 
are not repurchased, defeased, refinanced, extended or repaid prior to September 1, 2014, the HEP Amended Credit 
Agreement will expire on that date. 

HEP’s obligations under the HEP Amended Credit Agreement are collateralized by substantially all of HEP’s assets 
(presented  parenthetically  in  our  consolidated  balance  sheets).    Indebtedness  under  the  HEP  Amended  Credit 
Agreement is recourse to HEP Logistics Holdings, L.P., its general partner, and guaranteed by HEP’s wholly-owned 
subsidiaries.  Any recourse to the general partner would be limited to the extent of HEP Logistics Holdings, L.P.’s 
assets, which other than its investment in HEP, are not significant.  HEP’s creditors have no other recourse to our 
assets.  Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries.   

HollyFrontier Senior Notes  
Our senior notes consist of the following:

9.875% Senior Notes ($291.8 million principal amount maturing June 2017) 
6.875% Senior Notes ($150 million principal amount maturing November 2018)(1) 
8.5% Senior Notes ($200 million principal amount maturing September 2016)(1) 
(1) Represent senior notes assumed upon our July 1, 2011 merger with Frontier.  

In June 2009, we issued $200 million in aggregate principal amount of the 9.875% Senior Notes maturing June 15, 
2017.  A portion of the $187.9 million in net proceeds received was used for post-closing payments for inventories 
of crude oil and refined products acquired from Sunoco following the closing of the Tulsa West facility purchase on 
June  1,  2009.    In  October  2009,  we  issued  an  additional  $100  million  aggregate  principal  amount  as  an  add-on 
offering  to  the  9.875%  Senior  Notes  that  was  used  to  fund  the  cash  portion  of  our  acquisition  of  the  Tulsa  East 
facility.   

We have additional senior notes that we assumed as a result of our July 1, 2011 merger with Frontier; the 6.875% 
Senior  Notes  having  an  aggregate  principal  amount  of  $150  million  maturing  November  15,  2018  and  the  8.5% 
Senior Notes  having an aggregate principal amount of $200 million maturing September 15, 2016.   

These  senior  notes  (collectively,  the  “HollyFrontier  Senior  Notes”)  are  unsecured  and  impose  certain  restrictive 
covenants,  including  limitations  on  our  ability  to  incur  additional  debt,  incur  liens,  enter  into  sale-and-leaseback 
transactions, pay dividends, enter into mergers, sell assets and enter into certain transactions with affiliates.  At any 
time when the HollyFrontier Senior Notes are rated investment grade by both Moody’s and Standard & Poor’s and 
no default or event of default exists, we will not be subject to many of the foregoing covenants.  Additionally, we 
have certain redemption rights under each of the HollyFrontier Senior Notes. 

HollyFrontier Financing Obligation 
In October 2009, we sold approximately 400,000 barrels of crude oil tankage at our Tulsa West facility as well as 
certain crude oil pipeline receiving facilities to an affiliate of Plains for $40 million in cash.  In connection with this 
transaction, we entered into a 15-year lease agreement with Plains, whereby we agreed to pay a fixed monthly fee 
for the exclusive use of this tankage as well as a fee for volumes received at the receiving facilities purchased by 
Plains.  Additionally, we have a margin sharing agreement with Plains under which we will equally share contango 
profits with Plains for crude oil purchased by them and delivered to our Tulsa West facility for storage.  Due to our 
continuing  involvement  in  these  assets,  this  sale  and  lease  transaction  has  been  accounted  for  as  a  financing 
obligation.  As a result, we retained these assets on our books and recorded a liability representing the $40 million in 
proceeds received.

HEP Senior Notes 
HEP’s senior notes consist of the following:  

• 
• 

6.25% HEP Senior Notes ($185 million principal amount maturing March 2015) 
8.25% HEP Senior Notes ($150 million principal amount maturing March 2018) 

In  March  2010,  HEP  issued  $150  million  in  aggregate  principal  amount  of  8.25%  HEP  Senior  Notes  maturing 
March  15,  2018.    A  portion  of  the  $147.5  million  in  net  proceeds  received  was  used  to  fund  HEP’s  $93  million 
purchase of certain storage assets at our Tulsa East facility and Navajo Refinery Lovington facility  on March 31, 
2010.    Additionally,  HEP  used  a  portion  to  repay  $42  million  in  outstanding  HEP  Credit  Agreement  borrowings, 
with  the  remaining  proceeds  available  for  general  partnership  purposes,  including  working  capital  and  capital 
expenditures.  

HEP also has $185 million in aggregate principal amount of 6.25% HEP Senior Notes maturing March 1, 2015 that 
are registered with the SEC.   

These  HEP  senior  notes  (collectively,  the  “HEP  Senior  Notes”)  are  unsecured  and  impose  certain  restrictive 
covenants,  including  limitations  on  HEP’s  ability  to  incur  additional  indebtedness,  make  investments,  sell  assets, 
incur  certain  liens,  pay  distributions,  enter  into  transactions  with  affiliates,  and  enter  into  mergers.    At  any  time 
when the HEP Senior Notes are rated investment grade by both Moody’s and Standard & Poor’s and no default or 
event of default exists, HEP will not be subject to many of the foregoing covenants.  Additionally, HEP has certain 
redemption rights under the HEP Senior Notes.   

Indebtedness  under  the  HEP  Senior  Notes  is  recourse  to  HEP  Logistics  Holdings,  L.P.,  its  general  partner,  and 
guaranteed by HEP’s wholly-owned subsidiaries.  However, any recourse to the general partner would be limited to 
the  extent  of  HEP  Logistics  Holdings,  L.P.’s  assets,  which  other  than  its  investment  in  HEP,  are  not  significant.  
HEP’s creditors have no other 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  and  futures  contracts  to 
mitigate price exposure with respect to: 

• 
• 
• 
• 
• 

our inventory positions; 
natural gas purchases; 
costs of crude oil and related grade differentials;  
prices of refined products; and 
our refining margins. 

As  of December  31, 2011, we  have  outstanding  swap  contracts  serving as cash flow  hedges  against price  risk on 
forecasted 2012 purchases of 14,640,000 barrels of WTI crude oil and forecasted sales of 7,320,000 barrels of ultra-
low sulfur diesel and 7,320,000 barrels of conventional unleaded gasoline.  In the aggregate, these cash flow hedges 
effectively  hedge  our  gross  margin  on  forecasted  gasoline  and  diesel  sales,  totaling  40,000  BPD  in  2012.    These 
contracts  have  been  designated  as  accounting  hedges  and  are  measured  quarterly  at  fair  value  with  offsetting 
adjustments (gains/losses) recorded directly to other comprehensive income.  These fair value adjustments are later 
reclassified  in  the  income  statement  as  the  hedging  instruments  mature.    Also  on  a  quarterly  basis,  hedge 
effectiveness is measured by comparing the change in fair value of the swap contracts against the expected future 
cash  inflows/outflows  on  the  respective  transaction  being  hedged.    Any  ineffectiveness  is  recorded  to  cost  of 
products sold.  To date, ineffectiveness on these cash flow hedges have been insignificant.

We  also  have  swap  contracts  that  lock  in  the  spread  between  gasoline  and  butane  on  forecasted  sales  (112,500 
barrels of gasoline through January 2012) and NYMEX futures contracts to lock in prices on forecasted sales and 
purchases  of  inventory  (292,000  barrels  and  411,000  barrels,  respectively,  through  2013).    These  contracts  are 
measured quarterly at fair value with offsetting adjustments (gains/losses) recorded directly to cost of products sold. 

Interest Rate Risk Management 
HEP uses interest rate swaps to manage its exposure to interest rate risk.  

As  of  December  31,  2011  HEP  has  an  interest  rate  swap  contract  that  hedges  its  exposure  to  the  cash  flow  risk 
caused  by  the  effects  of  LIBOR  changes  on  a  $155  million  credit  agreement  advance.    This  interest  rate  swap 
effectively converts $155 million of LIBOR based debt to fixed rate debt having an interest rate of 0.99% plus an 
applicable margin, currently 2.50%, which equaled an effective interest rate of 3.49% as of December 31, 2011. This 
swap  matures  in  February  2016.    HEP  has  designated  this  interest  rate  swap  as  a  cash  flow  hedge.    To  date, 
ineffectiveness on this cash flow hedge has been insignificant. 

Prior to entering into the swap contract in December 2011 (discussed above), HEP terminated its previous interest 
rate swap that prior to settlement also served to hedge HEP’s exposure to the effects of LIBOR changes on the same 
$155  million  credit  agreement  advance.    HEP  terminated  this  swap  at  a  cost  of  $6  million,  to  lock  in  a  lower 
effective interest rate on this $155 million advance, which by means of the previous swap contract was effectively 
fixed at 6.24% at the time of termination.  

At December 31, 2011, HEP had a pre-tax accumulated other comprehensive loss of $6.5 million that relates to its 
current  and  previous  cash  flow  hedging  instruments.    Of  this  amount,  $6  million  relates  to  the  cash  flow  hedge 
terminated in December 2011 and represents the application of hedge accounting prior to termination.  This amount 
will be amortized as a charge to interest expense through February 2013, the remaining term of the terminated swap 
contract.  

The following table presents balance sheet locations and related fair values of outstanding derivative instruments. 
These amounts are presented on a gross basis in accordance with GAAP disclosure requirements and do not reflect 
the netting of asset or liability positions permitted under the terms of master netting arrangements.  Therefore, they 
are not equal to amounts presented in our consolidated balance sheets.  Additionally, we held $30 million of cash on 
margin  at  December  31,  2011  to  collateralize  certain  counterparty  positions.    These  deposits  have  an  offsetting 
current liability on our balance sheet and are not included in the amounts below.

At  December  31,  2011,  there  was  a  pre-tax  net  unrealized  gain  of  $172.8  million  classified  in  accumulated  other 
comprehensive  income  that  relates  to  our  commodity  cash  flow  hedges  and  HEP’s  cash  flow  hedge  of  interest.  
Assuming commodity prices and interest rates remain unchanged, an unrealized gain of approximately $173 million 
will  be  effectively  transferred  from  accumulated  other  comprehensive  income  into  the  income  statement  as  the 
hedging instruments mature over the next twelve-month period.   

For the year ended December 31, 2011, maturities and fair value adjustments attributable to our economic hedges 
resulted in decreases of $3.2 million to cost of products sold.  For the year ended December 31, 2010, we recognized 
a $1.3 million charge to cost of products sold and a $0.4 million charge to operating expenses that are attributable to 
losses resulting from fair value changes to our commodity price swap contracts. 

HEP  previously  had  interest  rate  swap  contracts  that  served  as  economic  hedges  on  interest  attributable  to 
outstanding debt. For the years ended December 31, 2010 and 2009, HEP recognized $1.5 million and $0.2 million, 
respectively, in non-cash charges to interest expense as a result of fair value changes to these swap contracts.

Included in the unrecognized tax benefits at December 31, 2011 are $2.2 million of 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. 

We recognize interest and penalties relating to liabilities for unrecognized tax benefits as an element of tax expense.  
During  the  year  ended  December  31,  2011,  we  recognized  a  $12.1  million  tax  benefit  (net  of  interest)  as  a 
component 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 do not expect that unrecognized 
tax  benefits  for  tax  positions  taken  with  respect  to  2011  and  prior  years  will  significantly  change  over  the  next 
twelve months. 

We  are  subject  to  U.S.  federal  income  tax,  Arizona,  Iowa,  New  Mexico,  Utah,  Oklahoma,  Kansas  and  Colorado 
income tax and to income tax of multiple other state jurisdictions.  We have substantially concluded all U.S. federal, 
state  and  local  income  tax  matters  for  tax  years  through  December  31,  2005.  In  late  2010,  the  Internal  Revenue 
Service  commenced  an  examination  of  our  U.S.  federal  tax  returns  for  the  tax  years  ended  December  31,  2006, 
2007, 2008 and 2009.  We anticipate that these audits will be completed by the end of 2012.

compensation agreements to provide funds for the payment of payroll and income taxes due at the vesting of share-based awards. 

On  August  3,  2011,  our  Board  of  Directors  declared  a  two-for-one  stock  split,  payable  in  the  form  of  a  common 
stock dividend for each issued and outstanding share of our common stock.  The stock dividend was paid August 31, 
2011  to  all  shareholders  of  record  on  August  24,  2011.    All  references  to  share  and  per  share  amounts  in  these 
consolidated financial statements and related disclosures have been adjusted to reflect the effect of the stock split for 
all periods presented. 

In September 2011, our Board of Directors approved a stock repurchase program of up to $100 million to repurchase 
common stock in the open market or through privately negotiated transactions. As of December 31, 2011, we had 
repurchased 586,123 shares at a cost of $17.8 million under this stock repurchase program. 

In  January  2012,  our  Board  of  Directors  approved  a  $350  million  stock  repurchase  program,  which  replaced  the 
existing  $100  million  stock  repurchase  program.    The  timing  and  amount  of  stock  repurchases  will  depend  on 
market  conditions,  corporate,  regulatory  and  other  relevant  considerations.  The  stock  repurchase  program  may  be 
discontinued at any time by the Board of Directors.   

During the years ended December 31, 2011, 2010 and 2009, we withheld shares of our common stock from certain 
employees in the amounts of $24.9 million, $1.2 million and $1.2 million, respectively.  These withholdings were

employees  who  elected  to  have  shares  withheld  from  vested  amounts  in  order  to  pay  such  taxes.    The  amounts 
withheld  in  2011  also  reflect  withholdings  associated  with  “change  in  control”  instant  vesting  provisions  of  the 
legacy Frontier stock awards.

NOTE 18:  Retirement Plans 

Retirement Plan 
We  sponsored  a  non-contributory  defined  benefit  retirement  plan  that  covered  most  legacy  Holly  non-union 
employees hired prior to January 1, 2007 and union employees hired prior to July 1, 2010.  This retirement plan was 
closed  to  new  entrants  effective  either  January  1,  2007  (for  non-union  employees)  or  July  1,  2010  (for  union 
employees).    Effective  January  1,  2012,  no  additional  benefits  will  be  accrued  under  this  plan  for  non-union 
employees participants. There will be a transition benefit over the next three years for active employees who have 
been 
the 
employer contribution feature of our defined contribution plan for all non-union employees.  

to  a  new  defined  contribution  plan.   Additionally, 

there will  be  changes 

transitioned 

in 

Our  funding  policy  for  this  defined  benefit  retirement  plan  is  to  make  annual  contributions  of  not  less  than  the 
minimum funding requirements of the Employee Retirement Income Security Act of 1974.  Benefits are based on 
the employee’s years of service and compensation. 

The  following  table  sets  forth  the  changes  in  the  benefit  obligation  and  plan  assets  of  our  retirement  plan  for  the

The  investment  policy  developed  for  the  HollyFrontier  Corporation  Pension  Plan  (the  “Plan”)  has  been  designed 
exclusively  for  the  purpose  of  providing  the  highest  probabilities  of  delivering  benefits  to  Plan  members  and 
beneficiaries.  Among the factors considered in developing the investment policy are: the Plans’ primary investment 
goal, rate of return objective, investment risk, investment time horizon, role of asset classes and asset allocation. 

The  most  important  component  of  the  investment  strategy  is  the  asset  allocation  between  the  various  classes  of 
securities  available  to  the  Plan  for  investment  purposes.    The  current  target  asset  allocation  is  32%  equity 
investments, 60% fixed income investments and 8% alternative investments.  Equity investments include a blend of 
domestic  growth  and  value  stocks  of  various  sizes  of  capitalization  and  international  stocks.    Debt  investments 
include  a  blend  of domestic  and global  debt  instruments.    Alternative  investments  include  a  single  fund  that  may 
invest  in  hedge  funds,  private  equity,  debt  or  real  estate  funds  or  other  investments.    The  equity  investments  are 
valued using quoted market prices, a Level 1 input and debt investments are valued using quoted market prices for 
similar  type  investments,  a  Level  2  input.    The  alternative  investments  may  be  valued  using  significant  other 
observable or unobservable inputs, Level 2 or 3 inputs.  See Note 4, Financial Instruments, for information on Level 
1, 2 and 3 inputs.

The overall expected long-term rate of return on Plan assets is 6.5% and is estimated using a financial simulation 
model  of  asset  returns.    Model  assumptions  are  derived  using  historical  data  given  the  assumption  that  capital 
markets are informationally efficient. 

We  expect  to  contribute  between  zero  and  $20  million  to  the  retirement  plan  in  2012.    Benefit  payments,  which 
reflect expected future service, are expected to be paid as follows: $5.9 million in 2012; $7.6 million in 2013; $7.2 
million in 2014; $6.4 million in 2015, $6.7 million in 2016 and $38.4 million in 2017-2021.  

Retirement Restoration Plan 
We  adopted  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.    Effective  January  1,  2012,  no  additional  benefits  will  be 
accrued under this plan. We expensed $0.6 million, $0.6 million and $0.7 million for the years ended December 31, 
2011, 2010 and 2009, respectively, in connection with this plan.  The accrued liability reflected in the consolidated 
balance sheets was $6.7 million and $6.2 million at December 31, 2011 and 2010, respectively.  As of December 31, 
2011, the projected benefit obligation under this plan was $6.7 million.  Benefit payments, which reflect expected 
future service, are expected to be paid as follows: $1.4 million in 2012; $0.5 million in 2013; $1.5 million in 2014; 
$0.4 million in 2015; $0.4 million in 2016; and $2.2 million in 2017-2021. 

Defined Contribution Plans 
We have defined contribution “401(k)” plans that cover substantially all employees.  Our contributions are based on 
employee’s compensation and partially match employee contributions.  We expensed $9.7 million, $5.5 million and 
$5 million for the years ended December 31, 2011, 2010 and 2009, respectively, in connection with these plans. 

Postretirement Medical Plans 
We provide postretirement  medical benefits to certain eligible employees.  These plans are unfunded and provide 
differing levels of benefits dependent upon hire date and work location.  Not all of our employees are covered by 
these plans at December 31, 2011. 

The following table sets forth the changes in the benefit obligation and plan assets of our postretirement plans for the 
years ended December 31, 2011 and 2010:

The  accumulated  benefit  obligation  was  $77.3  million  and  $7.9  million  at  December  31,  2011  and  2010, 
respectively.  The measurement dates used for our postretirement plans were December 31, 2011 and 2010. Benefit 
payments, which reflect expected future service, are expected to be paid as follows: $1.6 million in 2012; $2 million 
in 2013; $2.3 million in 2014; $2.6 million in 2015; $3 million in 2016; and $21.4 million in 2017 through 2021.

Rental  expense  charged  to  operations  was  $27  million,  $13.3  million  and  $11.8  million  for  the  years  ended 
December 31, 2011, 2010 and 2009, respectively.  Rental expense for the years ended December 31, 2011, 2010 and 
2009  includes  $7.4  million,  $7.1  million  and  $7.1  million,  respectively,  of  rental  expense  attributable  to  the 
operations of HEP. 

NOTE 20:  Contingencies and Contractual Obligations  

We are a party to various litigation and proceedings which 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. 

Contractual Obligations 
We have various long-term purchase obligations under certain crude oil and feedstock arrangements to ensure we 
have an adequate supply of crude oil and certain resources used to operate our refineries. The substantial majority of 
our purchase obligations are based on market prices or rates. These contracts expire in 2012 through 2023. 

We also have contractual obligations under agreements with third parties for the transportation and storage of crude 
oil, natural gas and feedstocks to our refineries under contracts expiring in 2016 through 2024.    

NOTE 21:  Segment Information  

Our operations are organized into two reportable segments, Refining and HEP.  Our operations that are not included 
in the Refining and HEP segments are included in Corporate and Other.  Intersegment transactions are eliminated in 
our consolidated financial statements and are included in Consolidations and Eliminations.  

The Refining segment represents the aggregate operations of El Dorado, Tulsa, Navajo, Cheyenne and Woods Cross 
Refineries and NK Asphalt.  Refining activities involve the purchase and refining of crude oil and wholesale and 
branded  marketing  of  refined  products,  such  as  gasoline,  diesel  fuel  and  jet  fuel.    These  petroleum  products  are 
primarily  marketed  in  the  Mid-Continent,  Southwest  and  Rocky  Mountain  regions  of  the  United  States.  
Additionally, the Refining segment includes specialty lubricant products produced at our Tulsa Refineries that are 
marketed  throughout  North  America  and  are  distributed  in  Central  and  South  America.    NK  Asphalt  operates 
various asphalt terminals in Arizona and New Mexico. 

The  HEP  segment  includes  all  of  the  operations  of  HEP,  a  consolidated  VIE,  which  owns  and  operates  logistic 
assets consisting of petroleum product and crude oil pipelines and terminal, tankage and loading rack facilities in the 
Mid-Continent, Southwest and Rocky Mountain regions of the United States.  Revenues are generated by charging 
tariffs for transporting petroleum products and crude oil through its pipelines, by leasing certain pipeline capacity to 
Alon  USA,  Inc.,  by  charging  fees  for  terminalling  refined  products  and  other  hydrocarbons  and  storing  and 
providing other services at its storage tanks and terminals. The HEP segment also includes a 25% interest in SLC 
Pipeline that serves refineries in the Salt Lake City, Utah area.  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.  Our revaluation of HEP’s 
assets  and  liabilities  at  March  1,  2008  (date  of  reconsolidation)  resulted  in  basis  adjustments  to  our  consolidated 
HEP balances.  Therefore, our reported amounts for the HEP segment may not agree to amounts reported in HEP’s 
periodic public filings. 

The accounting policies for our segments are the same as those described in the summary of significant accounting 
policies (see Note 1).

(1)  The Refining segment reflects the operations of the El Dorado and Cheyenne Refineries beginning July 1, 2011 (date of 
Holly-Frontier merger) and the operations of our Tulsa West and East facilities beginning June 1, 2009 and December 
1, 2009, respectively (dates of acquisition). 

HEP  segment  revenues  from  external  customers  were  $46.4  million,  $36  million  and  $45.5  million  for  the  years 
ended December 31, 2011, 2010 and 2009, respectively.   

NOTE 22:  Supplemental Guarantor/Non-Guarantor Financial Information 

Our obligations under the HollyFrontier Senior Notes have been jointly and severally guaranteed by the substantial 
majority of our existing and future restricted subsidiaries (“Guarantor Restricted Subsidiaries”).  These guarantees 
are  full  and  unconditional.    HEP,  in  which  we  have  a  42%  ownership  interest,  and  its  subsidiaries  (collectively, 
“Non-Guarantor  Non-Restricted  Subsidiaries”),  and  certain  of  our  other  subsidiaries  (“Non-Guarantor  Restricted 
Subsidiaries”) have not guaranteed these obligations. 

The  following  financial  information  presents  condensed  consolidating  balance  sheets,  statements  of  income,  and 
statements  of  cash  flows  of  HollyFrontier  Corporation  (the  “Parent”),  the  Guarantor  Restricted  Subsidiaries,  the 
Non-Guarantor  Restricted  Subsidiaries  and  the  Non-Guarantor  Non-Restricted  Subsidiaries.    The  information  has 
been  presented  as  if  the  Parent  accounted  for  its  ownership  in  the  Guarantor  Restricted  Subsidiaries,  and  the 
Guarantor  Restricted  Subsidiaries  accounted  for  the  ownership  of  the  Non-Guarantor  Restricted  Subsidiaries  and 
Non-Guarantor  Non-Restricted  Subsidiaries,  using  the  equity  method  of  accounting.    The  Guarantor  Restricted 
Subsidiaries and the Non-Guarantor Restricted Subsidiaries are collectively the “Restricted Subsidiaries.”   

Our  revaluation  of  HEP’s  assets  and  liabilities  at  March  1,  2008  (date  of  reconsolidation)  resulted  in  basis 
adjustments to our consolidated HEP balances.  Therefore, our reported amounts for the HEP segment may not agree 
to amounts reported in HEP’s periodic public filings.

annual revenues.  Sinclair accounted for $2,035.1 million (13%) and $1,616 million (19%) of our revenues for the 
years ended December 31, 2011 and 2010, respectively, and Shell Oil accounted for $1,540.6 million (10%) of our 
revenues for the year ended December 31, 2011.  We had no significant customers accounting for 10% or more of 
our annual revenues in 2009. Our export sales were to an affiliate of PEMEX and accounted for $370 million (2%), 
$323.2 million (4%) and $188.6 million (4%) of our revenues for the years ended December 31, 2011, 2010 and

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

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

Item 9A.  Controls and Procedures 

Evaluation of disclosure controls and procedures.  Our principal executive officer and principal financial officer 
have evaluated, as required by Rule 13a-15(b) under the Securities Exchange Act of 1934 (the “Exchange Act”), our 
disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e)) under the Exchange Act as of the 
end of the period covered by this annual report on Form 10-K.  Our disclosure controls and procedures are designed 
to provide reasonable assurance that the information we are required to disclose in the reports that we file or submit 
under the Exchange Act is accumulated and communicated to our management, including our principal executive 
officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is 
recorded,  processed,  summarized  and  reported  within  the  time  periods  specified  in  the  Securities  and  Exchange 
Commission’s rules and forms.  Based upon the evaluation, our principal executive officer and principal financial 
officer have concluded that our disclosure controls and procedures were effective as of December 31, 2011. 

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

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

Item 9B.  Other Information

that have not previously been reported.
