I am pleased to report that 2012 was an outstanding year 
both operationally and financially for HollyFrontier. We deliv-
ered strong operating performance at our refineries, generated 
record earnings and executed a capital return program that 
included dividends to our stockholders and stock repurchases. 
We are well positioned to continue building on the success 
of our tremendous year. 

Consistently Outstanding Financial Results
In 2012, we continued to benefit from attractive market  
conditions and structural advantages that give HollyFrontier  
a competitive edge in our industry. Our outstanding financial 
results reflect our prudent investments in our high-complexity 
refineries that resulted in our ability to process lower price 
crude feedstocks that are closer to our refineries than most 
refiners. Our performance also reflects our favorable geo-
graphic position that allows our refineries to be located near 
the markets we serve in the middle of the country. 

The numbers are terrific – in 2012 we achieved:

•  Net Income attributable to HFC stockholders of $1.7 billion

•  Gross refining margins of $24.89 per produced barrel

•  Record operating cash flow of $1.7 billion

•   One of the strongest balance sheets in our industry.  

As of December 31, 2012, we had $2.4 billion in cash  
and short-term investments, compared to $1.3 billion in  
long-term debt. 

These 2012 financial results underscore the fundamental 
strength of our business and reaffirm the benefits of the  
strategic plan we have successfully executed since completing 
the HollyFrontier merger in 2011. 

Delivering Value by Returning Capital to Stockholders 
In 2012, HollyFrontier returned over $860 million to stock-
holders through regular dividends, special dividends and 
share repurchases. During the year, the HollyFrontier Board  
of Directors increased the Company’s regular quarterly cash 
dividend by 100% – from $0.10 per share to $0.20 per share – 
and approved five special dividends of $0.50 per share each. 
On an annualized basis, the Company’s cash dividend yield 
was approximately 7% as of year end. In addition, the Board of 
Directors authorized $700 million of share repurchases during 
the year, and we completed the repurchase of $210 million 
worth of shares. Overall, since completing the HollyFrontier 
merger in July 2011, the Company has more than doubled its 
earnings and has returned over $1.1 billion in capital to stock-
holders through dividends and share repurchases.

As we look forward, we expect that the structural advantages 
that are currently increasing our operating margins will  
continue to drive strong free cash generation, allowing us  
to maintain our strategy of providing substantial cash returns  
to our stockholders.

Operational Excellence
Operations are running well across our refineries, which are 
among the most complex in the industry and have the ability to 
process domestic and Canadian crudes. We have reinvested 
over $1 billion of cash flow generated in recent years into our 
facilities, with the goal of improving our refining capabilities. 
This investment in the safety, efficiency and processing 
capacity of our facilities is a critical element of our mission 
and values.

HollyFrontier Corporation 2012 Annual Report

 
“ 2012 financial results underscore the fundamental 
strength of our business and reaffirm the benefits 
of the strategic plan we have successfully executed 
since completing the merger of HollyFrontier  
in 2011.”

  Michael C. Jennings

Operational highlights in 2012 include: 

•   Record throughput levels. Overall crude throughput  
levels increased over 2011, with our El Dorado and  
Navajo refineries reaching record annual levels of  
131,400 and 93,800 BPD, respectively. 

•   Increased processing of heavy and sour crude.  

We increased our processing of heavy and sour crude  
feedstocks from 35% of our total crude slate in 2011  
to 39% in 2012.

•   Completion of capital improvement projects. Capital 

improvement projects completed in 2012 include MSAT2/ 
liquid yield improvements at the Navajo and Woods Cross 
refineries, a new coker charge heater at El Dorado and an 
FCC flu gas scrubber at Woods Cross. 

•   Start-up of the UNEV Pipeline. In early 2012, the UNEV 
pipeline, our 400-mile, 12-inch refined products line that 
runs from Salt Lake City to Las Vegas, became fully  
operational. The UNEV pipeline enables us to supply the 
Las Vegas and Cedar City markets at a considerable cost  
advantage to our competitors.

•   Sale of 75% UNEV Pipeline interest to Holly Energy  

Partners. In July 2012, we sold our 75% interest in the 
UNEV Pipeline to Holly Energy Partners, our Master Limited  
Partnership, for $315 million. The UNEV dropdown trans-
action reflects the synergistic nature of our refining and 
related logistics operations.

•   Woods Cross refinery expansion and modernization program. 
We announced an agreement with Newfield Exploration 
Company to supply waxy crude upon completion of the 
ongoing modernization and expansion of our Woods Cross 
refinery. This will provide increased capacity to serve the 
important Las Vegas market through the UNEV Pipeline,  
as well as our traditional customers in Salt Lake City and  
the Inter-Mountain West.

Health, safety and environmental stewardship remain  
our top corporate values. We continue to execute on an 
expectation that “no one gets hurt” and “nothing gets 
harmed” as we conduct everyday operations at all of  
our facilities. 

HollyFrontier’s outstanding operational performance is 
the result of the dedication and efforts of the Company’s  
talented employees. Our 2,500 employees do a terrific  
job every day efficiently and safely running our operations.  
Their hard work has enabled HollyFrontier to deliver the  
outstanding results we achieved in 2012. We extend our  
deepest appreciation and thanks to our employees for their  
service and hard work.

In addition, we would like to thank Matthew Clifton, who retired 
as Executive Chairman of HollyFrontier on January 1, 2013.  
We are extremely appreciative of his 30 plus years of leadership 
and service to HollyFrontier and its predecessors, and we are 
pleased that he will continue as Chairman and CEO of Holly 
Energy Partners.

Looking Ahead
We are excited about where we are as a company today. 
Financially and operationally, HollyFrontier is firing on all  
cylinders, and we believe the Company is well positioned  
for the future, even when market conditions inevitably shift. 
We look forward to continuing to meet our standards of  
operational excellence, execute on our strategic goals  
and enhance value for our stockholders.

Sincerely,

Michael C. Jennings
Chairman, Chief Executive Officer and President

COMPANY OVERVIEW

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

We merged with Frontier Oil Corporation (“Frontier”) on 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. 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. This merger combined the legacy Frontier refinery operations consisting of refineries in El Dorado, Kansas (the “El 
Dorado  Refinery”)  and  Cheyenne,  Wyoming  (the  “Cheyenne  Refinery”)  with  Holly’s  legacy  refinery  operations  to  form 
HollyFrontier. 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 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 several acquisitions between 2009 and 2012. 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.”

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.

Table of Content

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 and vacuum 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 All American 
Pipeline, L.P. (“Plains”). 

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

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 year ended December 31, 2012, sales to Shell represented approximately 35% of the El Dorado Refinery's total sales and 
12% of our total consolidated sales. We have an offtake agreement with Shell Oil Products US (“Shell”) under which Shell purchases 
gasoline, diesel and jet fuel production of the El Dorado Refinery at market-based prices through December 2014. In 2012, we 
retained and marketed 76,000 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  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 in 2009, 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, 2012, sales to Sinclair 
represented approximately 36% of the Tulsa Refineries total sales and 10% of our total consolidated sales.

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

Our Tulsa West facility also produces specialty lubricant products sold in both commercial and specialty markets throughout North 
America and to customers with operations in Central America and South America. The specialty lubricant products are high value 
products that provide a significantly higher margin contribution to the refinery. Base oil customers include blender-compounders 
who  prepare  the  various  finished  lubricant  and  grease  products  sold  to  end  users. Agricultural  products  are  formulated  as 
supplemental carriers for herbicides and as Environmental Protection Agency (“EPA”) registered pesticide oils, are sold to product 
formulators. Process oil customers include rubber and chemical industry customers. Specialty waxes are sold primarily to packaging 
customers as coating material for paper and cardboard, and to non-packaging customers in the construction materials, adhesive 
and candle-making markets. Our production represents approximately 6% of paraffinic oil capacity and 13% of wax production 
capacity in the United States market and is one of four refineries of specialty aromatic oils in North America.

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 50,000 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.

Southwest Region (Navajo Refinery)

Facilities
The Navajo Refinery has a crude oil capacity of 100,000 barrels per stream day and has the ability to process sour crude oils into

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 2.0 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, 
petroleum products from the Navajo Refinery are transported 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 Phillips 66 and EnCana Corp.), Valero, Alon and 
Western Refining. Pipelines serving this market are owned by 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 from the Texas Gulf Coast to El Paso and, through interconnections with third-party 
common carrier pipelines, into the Arizona market.

New Mexico Markets

Table of Content

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, 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 as well as into southern Colorado and northern 
Arizona.

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 barrels per stream day and the Woods Cross Refinery has a crude oil 
capacity of 31,000 barrels per stream day. 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 2012, gasoline and diesel fuel (excluding volumes 
purchased for resale) represented 55% and 32%, 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 1.9 million barrels of feedstock and product tankage, of which 1.8 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 $225.0 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 a definitive agreement with Western for the purchase 
of the Bloomfield units.

14

Table of Content

In conjunction with the expansion, we signed a 10-year, 20,000 BPD crude oil supply agreement with Newfield Exploration 
Company. This agreement, which commences upon completion of the expansion, will supply black and yellow wax crude oil 
produced in the nearby Uinta Basin to the Woods Cross Refinery, 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, Wyoming refineries near Rawlins and in Casper owned by Sinclair and a refinery in Denver owned by Suncor. Five product 
pipelines also supply Denver, including three from outside the region. 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. In addition to our Woods Cross Refinery, local area refiners include Chevron, Tesoro, Big West and Silver Eagle. Other 
refiners that ship via the Pioneer Pipeline include Sinclair, ExxonMobil and Phillips 66. 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 Phillips 66. Approximately 40% - 45% of the gasoline and diesel fuel produced by our Woods Cross Refinery is sold through 
a network of Phillips 66 branded marketers under a long-term supply agreement.

Idaho, Wyoming, Eastern Washington and Nevada Markets
We supply a small percentage of the refined products consumed in the combined Idaho, Wyoming, eastern Washington and Nevada 
markets. Our Woods Cross Refinery ships refined products over 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. In 2012, we began shipping refined products to Las Vegas, Nevada via the UNEV Pipeline. The majority of the 
Las Vegas, Nevada market for refined products is supplied by various West Coast refiners and suppliers via Kinder Morgan's 
CalNev common carrier pipeline system.

HOLLY ENERGY PARTNERS, L.P. 

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

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

HEP's recent acquisitions (2009 through 2012) are summarized below: 

2012 Acquisition

UNEV Interest Transaction
On July 12, 2012, HEP acquired from us our 75% interest in UNEV. We received consideration consisting of $260.0 million in 
cash and 1.0 million HEP common units. UNEV owns the UNEV Pipeline, a 12-inch refined products pipeline running from Salt 
Lake City, Utah to Las Vegas, Nevada together with terminal facilities in Cedar City, Utah and North Las Vegas. The UNEV 
Pipeline was completed in late 2011 and became operational during the first quarter of 2012.

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 $150.0 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 $93.0 million, consisting of hydrocarbon storage tanks having 
approximately 2.0 million barrels of storage capacity, a rail loading rack and a truck unloading rack located at our Tulsa East 
facility and an asphalt loading rack facility located at our Navajo Refinery facility located in Lovington, New Mexico.

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.  

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 $35.0 million.

Transportation Agreements

Agreements with HEP
HEP serves our refineries under long-term pipeline and terminal, tankage and throughput agreements expiring in 2019 through 
2026. Under these agreements, we pay HEP fees to transport, store and throughput volumes of refined product and crude oil on 
HEP's pipeline and terminal, tankage and loading rack facilities that result in minimum annual payments to HEP including UNEV 
(a consolidated subsidiary of HEP). Under these agreements, the agreed upon tariff rates are subject to annual tariff rate adjustments 
on July 1 at a rate based upon the percentage change in Producer Price Index (“PPI”) or Federal Energy Regulatory Commission 
(“FERC”) index. As of December 31, 2012, these agreements result in minimum annualized payments to HEP of $217.2 million.

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

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

As of December 31, 2012, HEP's assets include:

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. Additionally, the EPA has the authority under the CAA to 
modify the formulation of the refined transportation fuel products we manufacture in order to limit the emissions associated with 
their final use. 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.

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 on 
January 1, 2014. Recently completed capital projects at our Tulsa, Navajo and Woods Cross Refineries and capital projects planned 
for completion at our Cheyenne Refinery in 2013 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 benzene credits. 

The Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007 prescribe certain percentages of renewable 
fuels (e.g., ethanol and biofuels) that, where required, must be blended into our produced gasoline and diesel. Additional changes 
in fuel standards to reduce vehicle emissions are expected to be proposed in 2013. 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. Litigation challenging the EPA's authority over greenhouse gas emissions also is pending in federal 
court. The U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit) decided in 2012 to uphold the rules, but 
petitions for U.S. Supreme Court review are expected.

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

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 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, 2012, we had an accrual of $88.9 million 
related to such environmental liabilities.

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

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

Health  and  environmental  legislation  and  regulations  change  frequently.  We  cannot  predict  what  additional  health  and 
environmental  legislation  or  regulations  will  be  enacted  or  become  effective  in  the  future  or  how  existing  or  future  laws  or 
regulations will be administered or interpreted with respect to our operations. Compliance with more stringent laws or regulations 
or adverse changes in the interpretation of existing laws or regulations by government agencies could have an adverse effect on 
our financial position and the results of our operations and could require substantial expenditures for the installation and operation 
of systems and equipment that we do not currently possess.

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

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

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, regional 
and grade differentials and governmental regulations and policies. 

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

We do not produce crude oil and must purchase all our crude oil, the price of which fluctuates based upon worldwide and local 
market conditions. Our profitability depends largely on the spread between market prices for refined petroleum products and crude 
oil prices. This margin is continually changing and may fluctuate significantly from time to time. Crude oil and refined products 
are commodities whose price levels are determined by market forces beyond our control. For example, the reversal of certain 
existing pipelines or the construction of certain new pipelines transporting additional crude oil or refined products to markets that 
serve competing refineries could affect the market dynamic that has allowed us to take advantage of favorable pricing. Additionally, 
due to the seasonality of refined products markets and refinery maintenance schedules, results of operations for any particular 
quarter of a fiscal year are not necessarily indicative of results for the full year. In general, prices for refined products are influenced 
by the price of crude oil. Although an increase or decrease in the price for crude oil may result in a similar increase or decrease 
in prices for refined products, there may be a time lag in the realization of the similar increase or decrease in prices for refined 
products. The effect of changes in crude oil prices on operating results therefore depends in part on how quickly refined product 
prices adjust to reflect these changes. A substantial or prolonged increase in crude oil prices without a corresponding increase in 
refined product prices, a substantial or prolonged decrease in refined product prices without a corresponding decrease in crude oil 
prices, or a substantial or prolonged decrease in demand for refined products could have a significant negative effect on our earnings 
and cash flow. Also, crude oil supply contracts are generally short-term contracts with market-responsive pricing provisions. We 
purchase our refinery feedstocks weeks before manufacturing and selling the refined products. Price level changes during the 
period between purchasing feedstocks and selling the manufactured refined products from these feedstocks could have a significant 
effect on our financial condition and results of operations.

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

One of the ways we may grow our business is through the construction of new refinery processing units (or the purchase and 
refurbishment of used units from another refinery) and the expansion of existing ones. Projects are generally initiated to increase 
the yields of higher-value products, increase the amount of lower cost crude oils that can be processed, increase refinery production 
capacity, meet new governmental requirements, or maintain the operations of our existing assets. Additionally, our growth strategy 
includes projects that permit access to new and/or more profitable markets. The construction process involves numerous regulatory, 
environmental, political, and legal uncertainties, most of which are not fully within our control, including: 

• 

denial or delay in issuing requisite regulatory approvals and/or permits;

21

Table of Content

• 
• 
• 
• 

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.

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

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

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

• 
• 

• 

• 

• 

• 
• 
• 

diversion of management time and attention from our existing business;
challenges in managing the increased scope, geographic diversity and complexity of operations and inefficiencies that 
may result therefrom;
difficulties in integrating the financial, technological and management standards, processes, procedures and controls of 
an acquired business with those of our existing operations;
liability for known or unknown environmental conditions or other contingent liabilities not covered by indemnification 
or insurance;
greater than anticipated expenditures required for compliance with environmental or other regulatory standards or for 
investments to improve operating results;
difficulties or delays in achieving anticipated operational improvements or benefits;
incurrence of additional indebtedness to finance acquisitions or capital expenditures relating to acquired assets; and
issuance of additional equity, which could result in further dilution of the ownership interest of existing stockholders.

Any acquisitions that we do consummate may have adverse effects on our business and operating results. 

22

Table of Content

We may not be able to obtain funding on acceptable terms or at all because of volatility and uncertainty in the credit and capital 
markets. This may hinder or prevent us from meeting our future capital needs.

The domestic and global financial markets and economic conditions are disrupted and volatile from time to time due to a variety 
of  factors,  including  low  consumer  confidence,  high  unemployment,  geoeconomic  and  geopolitical  issues,  weak  economic 
conditions and uncertainty in the financial services sector. In addition, the fixed-income markets have experienced periods of 
extreme volatility, which negatively impacted market liquidity conditions. As a result, the cost of raising money in the debt and 
equity  capital  markets  has  increased  substantially  at  times  while  the  availability  of  funds  from  these  markets  diminished 
significantly. In particular, as a result of concerns about the stability of financial markets generally and the solvency of lending 
counterparties specifically, the cost of obtaining money from the credit markets may increase as many lenders and institutional 
investors increase interest rates, enact tighter lending standards, refuse to refinance existing debt on similar terms or at all and 
reduce, or in some cases cease, to provide funding to borrowers. In addition, lending counterparties under 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 or we may be required to sell 
assets. Moreover, without adequate funding, we may be unable to execute our growth strategy, complete future acquisitions or 
construction projects, take advantage of other business opportunities or respond to competitive pressures, comply with regulatory 
requirements, or meet our short-term or long-term working capital requirements, any of which could have a material adverse effect 
on our revenues and results of operations. Failure to comply with regulatory requirements in a timely manner or meet our short-
term or long-term working capital requirements could subject us to regulatory action.

We 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. 

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. 
Failure to appropriately manage occupational health and safety risks associated with our business could also adversely impact 
employees, communities, stakeholders, our reputation and our results of operations.

23

Table of Content

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 demand for our products and 
our results of operations.  

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

From time to time, new federal energy policy legislation is enacted by the U.S. Congress. 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 reduction in emissions of GHGs from motor vehicles and the other of 
which may require permits for emissions of GHGs from certain large stationary sources. The EPA’s rules relating to emissions of 
GHGs from large stationary sources of emissions were upheld by the D.C. Circuit, but numerous parties are expected to seek U.S. 
Supreme Court review of that decision in 2013. The EPA has also adopted rules requiring the reporting of GHG emissions from 
specified large GHG emission sources in the United States, including petroleum refineries, on an annual basis. The EPA has also 
announced its intention to issue a New Source Performance Standard directly regulating GHG emissions from refineries.

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

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

24

Table of Content

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. 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 major 
capital investment, various environmental compliance related projects, regulatory requirements or competitive pressures could 
result in additional capital expenditures, which may not produce a return on investment. Such capital expenditures may require 
significant financial resources that may be contingent on our access to capital markets and commercial bank loans. Additionally, 
other matters, such as regulatory requirements or legal actions, may restrict our access to funds for capital expenditures. 

Our refineries consist of many processing units, a number of which have been in operation for many years. One or more of the 
units may require unscheduled downtime for unanticipated maintenance or repairs that are more frequent than our scheduled 
turnaround for such units. Scheduled and unscheduled maintenance could reduce our revenues during the period of time that the 
units  are  not  operating. We  have  taken  significant  measures  to  expand  and  upgrade  units  in  our  refineries  by  installing  new 
equipment and redesigning older equipment to improve refinery capacity. The installation and redesign of key equipment at our 
refineries  involves  significant  uncertainties,  including  the  following:  our  upgraded  equipment  may  not  perform  at  expected 
throughput levels; operating costs of the upgraded equipment may be higher than expected; the yield and product quality of new 
equipment may differ from design and/or specifications and redesign, modification or replacement of the equipment may be 
required to correct equipment that does not perform as expected, which could require facility shutdowns until the equipment has 
been redesigned or modified. Any of these risks associated with new equipment, redesigned older equipment, or repaired equipment 
could lead to lower revenues or higher costs or otherwise have a negative impact on our future financial condition and results of 
operations.

In addition, we expect to execute turnarounds at our refineries, which involve numerous risks and uncertainties. These risks include 
delays and incurrence of additional and unforeseen costs. The turnarounds allow us to perform maintenance, upgrades, overhaul 
and repair of process equipment and materials, during which time all or a portion of the refinery will be under scheduled downtime.  

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

Our operations are subject to operational hazards and unforeseen interruptions such as natural disasters, adverse weather, accidents, 
fires, explosions, hazardous materials releases, power failures, mechanical failures and other events beyond our control. These 
events might result in a loss of equipment or life, injury, or extensive property damage or destruction of property, as well as a 
curtailment or an interruption in our operations and may affect our ability to meet marketing commitments. We maintain significant 
insurance coverage, but it does not cover all potential losses, costs or liabilities, and our business interruption insurance coverage 
generally does not apply unless a business interruption exceeds 45 days. If any refinery were to experience an interruption in 
operations, earnings from the refinery could be materially adversely affected (to the extent not recoverable through insurance) 
because of lost production and repair costs.

25

Table of Content

The availability of adequate insurance may be affected by conditions in the insurance market over which we have no control, 
resulting in the inability to maintain or obtain insurance of the type and amount we desire at reasonable rates. As a result of market 
conditions, premiums and deductibles for certain of our insurance policies could increase or, in some instances, certain insurance 
could become unavailable or available only for reduced amounts of coverage. We could suffer losses for uninsurable or uninsured 
risks or in amounts in excess of our existing insurance coverage. The occurrence of an event that is not fully covered by insurance 
could have a material adverse effect on our business, financial condition and results of operations.

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

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

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

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

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

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

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

A 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. 

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

We utilize various common carrier or other third party pipeline systems to deliver our products to market. The key systems utilized 
by 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 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. 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 44% 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 
2026. Furthermore, our financial statements include the consolidated results of HEP. HEP is subject to its own operating and 
regulatory risks, including, but not limited to: 

• 
• 
• 
• 
• 
• 
• 

its reliance on its significant customers, including us;
competition from other pipelines;
environmental regulations affecting pipeline operations;
operational hazards and risks;
pipeline tariff regulations affecting the rates HEP can charge;
limitations on additional borrowings and other restrictions due to HEP's debt covenants; and
other financial, operational and legal risks.

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

For additional information about HEP, see “Holly Energy Partners, L.P.” under Items 1 and 2, “Business and Properties.” For risks 
related to HEP's business, see Item 1A of HEP's Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

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

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

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

Any substantial increase in the nonpayment and/or nonperformance by our customers or vendors could have a material adverse 
effect on our results of operations and cash flows.

Terrorist attacks, and the threat of terrorist attacks or domestic vandalism, have resulted in increased costs to our business. 
Continued global hostilities or other sustained military campaigns may adversely impact our results of operations. 

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

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

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 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. 

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

In 2010, the EPA and the National Highway Traffic Safety Administration (“NHTSA”) finalized new standards, raising the required 
Corporate Average Fuel Economy (“CAFE”) of the nation's passenger fleet by 40% to approximately 35 miles per gallon (“m.p.g.”) 
by 2016 and imposing the first-ever federal GHG emissions standards on cars and light trucks. In September 2011, the EPA and 
the Department of Transportation finalized first-time standards for fuel economy of medium and heavy duty trucks. On August 
28, 2012 the EPA and NHTSA adopted standards through model year 2025 in two phases. The first phase establishes final standards 
for 2017-2021 model year vehicles that are projected to require 40.3 - 41.0 m.p.g. in model year 2021 on an average industry fleet-
wide basis. The second phase of the CAFE program represents non-final “augural” standards for 2022-2025 model year vehicles 
that are projected to require 48.7 - 49.7 m.p.g. in model year 2025, on an average industry fleet-wide basis. Such increases in fuel 
economy standards, along with mandated increases in use of renewable fuels discussed above, could result in decreasing demand 
for petroleum fuels. Decreasing demand for petroleum fuels could have a material effect on our financial condition and results of 
operation.

We may be unable to pay future regular and/or special dividends. 

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

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

A significant portion of our operating responsibility on refined product pipelines is to insure the quality and purity of the products 
loaded at our loading racks. If our quality control measures were to fail, we may have contaminated or off-specification commingled 
pipelines and storage tanks or off-specification product could be sent to public gasoline stations. These types of incidents could 
result in product liability claims from our customers.

Product liability is a significant commercial risk. Substantial damage awards have been made in certain jurisdictions against 
manufacturers and resellers based upon claims for injuries caused by the use of or exposure to various products. There can be no 
assurance that product liability claims against us would not have a material adverse effect on our business or results of operations 
or our ability to maintain existing customers or retain new customers.

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

We periodically enter into derivative transactions as it relates to inventory levels and/or future production to manage the risks from 
changes in the prices of crude oil, refined products and other feedstocks. These transactions limit our potential gains if commodity 
prices move above or below the certain price levels established by our hedging instruments. We hedge price risk on inventories 
above our target levels to minimize the impact these price fluctuations have on our earnings and cash flows. Consequently, our 
hedging results may fluctuate significantly from one reporting period to the next depending on commodity price fluctuations and 
our relative physical inventory positions. These transactions may also expose us to risks of financial losses; for example, if our 
production is less than we anticipated at the time we entered into a hedge agreement or if a counterparty to our hedge agreements 
fails to perform its obligations under the agreements.

Changes in our credit profile, or a significant increase in the price of crude oil, may affect our relationship with our suppliers, 
which could have a material adverse effect on our liquidity and limit our ability to purchase sufficient quantities of crude oil 
to operate our refineries at desired capacity.

An unfavorable credit profile, or a significant increase in the price of crude oil, could affect the way crude oil suppliers view our 
ability to make payments and induce them to shorten the payment terms of their invoices with us or require credit enhancement. 
Due to the large dollar amounts and volume of our crude oil and other feedstock purchases, any imposition by our suppliers of 
more burdensome payment terms or credit enhancement requirements on us may have a material adverse effect on our liquidity 
and our ability to make payments to our suppliers. This in turn could cause us to be unable to operate our refineries at desired 
capacity. A failure to operate our refineries at desired capacity could adversely affect our profitability and cash flow. 

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 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, 2012, approximately 34% 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. 

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

Propane Pit - Woods Cross
In December 2011, the EPA conducted an inspection at Woods Cross and identified some alleged violations of the Chemical 
Accident Prevention and Risk Management Plan (“RMP”) requirements set forth in section 112(r)(7) of the Federal Clean Air Act 
and Part 68 of Title 40 of the Code of Federal Regulations. Following extended negotiations, Holly Refining & Marketing – Woods 
Cross LLC and the EPA on October 12, 2012 agreed to resolve this matter with a civil penalty of $115,000, subject to the parties' 
agreement on the final terms of two documents – an Administrative Compliance Order on Consent (“ACOC”) specifying the 
details of the closure of the Frozen Earth Propane Storage Pit and a Combined Complaint and Consent Agreement (“CCCA”) 
detailing the EPA allegations and resolution of those allegations. Neither of these agreements require Holly Refining & Marketing 
– Woods Cross LLC to admit or deny the EPA's allegations. As of December 14, 2012, the ACOC and CCCA were signed by all 
required parties and are now final.

Additional Environmental Matters
We are reporting the following proceedings to comply with SEC regulations which require us to disclose proceedings arising under 
federal, state or local provisions regulating the discharge of materials into the environment or protecting the environment if we 
reasonably believe that such proceedings may result in monetary sanctions of $100,000 or more. Our respective subsidiaries have 
or will develop corrective action plans regarding these disclosures that will be implemented in consultation with the respective 
federal and state agencies. It is not possible to predict the ultimate outcome of these proceedings, although none are currently 
expected to have a material effect on our consolidated financial position. 

Frontier Refining LLC (“FR”), our wholly-owned subsidiary, has undertaken environmental audits at the Cheyenne Refinery 
regarding compliance with federal and state air quality and waste requirements. By letters dated October 5, 2012, and November 
7, 2012, FR submitted reports to the EPA voluntarily disclosing non-compliance with certain emission limitations, reporting, and 
other provisions of a 2009 federal consent decree. By letter dated January 10, 2013, FR submitted to the EPA a voluntary self-
disclosure of preliminary audit findings consistent with the EPA’s Audit Policy. By letter dated October 31, 2012, FR submitted 
a preliminary report to the Wyoming Department of Environmental Quality (“WDEQ”) voluntarily disclosing non-compliance 
with certain notification, reporting, and other provisions of the refinery's state air permits and other regulatory requirements. The 
Cheyenne Refinery also has four outstanding Notices of Violations issued in 2010, 2011 and 2013 that are subject to ongoing 
settlement negotiations with the WDEQ. Additional air, water and waste audits are ongoing or planned for the Cheyenne Refinery 
for 2013.

Ethanol Management Company LLC (“EMC”), our wholly-owned subsidiary, has undertaken an environmental audit at the terminal 
located  in  Henderson,  Colorado  regarding  compliance  with  the  hazardous  waste  requirements  administered  by  the  Colorado 
Department of Public Health and Environment (“CDPHE”). By letter dated November 7, 2012, EMC notified the CDPHE of non-
compliance under hazardous waste regulations associated with waste water storage, and on February 4, 2013, the CDPHE notified 
EMC that this matter is formally closed and no action will be taken in response to the self-disclosure.

Between November 2010 and February 2012, certain of our subsidiaries submitted multiple reports to the EPA to voluntarily 
disclose non-compliance with fuels regulations at the Cheyenne, El Dorado, Navajo, Tulsa and Woods Cross refineries and at the 
Cedar City, Utah and Henderson, Colorado terminals. The EPA has requested additional information regarding certain of these 
reports, and our subsidiaries have complied with all requests received to date.

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.

In January 2012, our Board of Directors approved a $350 million stock repurchase program, and in June 2012, approved an 
additional $350 million repurchase program that authorizes us to repurchase common stock in the open market or through privately 
negotiated transactions. The timing and amount of stock repurchases will depend on market conditions, corporate, regulatory and 
other relevant considerations. These programs may be discontinued at any time by the Board of Directors. The following table

(1)  The December 2012 shares repurchased were not purchased under our approved stock repurchase program, but rather pursuant to separate 
authority from our Board of Directors. These repurchases were made in the open market.

As of February 13, 2013, we had approximately 88,000 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 “Debt” in the Notes to Consolidated Financial Statements.

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 on 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 own and operate refineries having a combined crude oil 
processing capacity of 443,000 barrels per day that serve markets throughout the Mid-Continent, Southwest and Rocky Mountain 
regions of the United States. Our refineries are located in El Dorado, Kansas (the El Dorado Refinery), Tulsa, Oklahoma (the Tulsa 
Refineries), which comprise two production facilities, the Tulsa West and East facilities, a petroleum refinery in Artesia, New 
Mexico, which operates in conjunction with crude, vacuum distillation and other facilities situated 65 miles away in Lovington, 
New Mexico (the Navajo Refinery), Cheyenne, Wyoming (the Cheyenne Refinery) and Woods Cross, Utah (the Woods Cross 
Refinery).

Our  discussion  of  financial and  operating results  for  the  years  ended December 31,  2012,  2011 and  2010  is  presented  in  the 
following section.

(1)  Earnings before interest, taxes, depreciation and amortization, which we refer to as “EBITDA,” is calculated as net income 
plus (i) interest expense, net of interest income, (ii) income tax provision, and (iii) depreciation and amortization. EBITDA 
is not a calculation provided for under GAAP; however, the amounts included in the EBITDA calculation are derived from 
amounts included in our consolidated financial statements. EBITDA should not be considered as an alternative to net income 
or operating income as an indication of our operating performance or as an alternative to operating cash flow as a measure 
of liquidity. EBITDA is not necessarily comparable to similarly titled measures of other companies. EBITDA is presented 
here because it is a widely used financial indicator used by investors and analysts to measure performance. EBITDA is also 
used by our management for internal analysis and as a basis for financial covenants. 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 organized into two reportable segments, Refining and HEP. See Note 21 “Segment Information” in the Notes 
to Consolidated Financial Statements for additional information on our reportable segments.

Refining Operating Data

Our refinery operations include the El Dorado, Tulsa, Navajo, Cheyenne and Woods Cross Refineries. The following tables set 
forth information, including non-GAAP performance measures about our consolidated refinery operations. The cost of products 
and refinery gross and net operating margins do not include the effect of depreciation and amortization. Reconciliations to amounts

Results of Operations – Year Ended December 31, 2012 Compared to Year Ended December 31, 2011 

Summary
Net income attributable to HollyFrontier stockholders for the year ended December 31, 2012 was $1,727.2 million ($8.41 per 
basic and $8.38 per diluted share), a $703.8 million increase compared to $1,023.4 million ($6.46 per basic and $6.42 per diluted 
share) for the year ended December 31, 2011. Net income increased due principally to greater operating scale following our July 
1, 2011 merger and higher refining margins in the current year. Refinery gross margins for the year ended December 31, 2012 
increased to $24.89 per produced barrel compared to $20.64 for the year ended December 31, 2011.

Sales and Other Revenues
Sales and other revenues increased 30% from $15,439.5 million for the year ended December 31, 2011 to $20,090.7 million for 
the year ended December 31, 2012, due principally to the inclusion of sales volumes and related revenues attributable to the El 
Dorado and Cheyenne Refineries for a full year period and higher sales volumes of refined products produced from the legacy 
Holly refineries. Additionally, the average sales price we received per produced barrel sold increased 1% from $118.82 for the 
year ended December 31, 2011 to $119.48 for the year ended December 31, 2012. Sales and other revenues for the years ended 
December 31, 2012 and 2011 include $47.6 million and $46.4 million, respectively, in HEP revenues attributable to pipeline and 
transportation services provided to unaffiliated parties.

Cost of Products Sold
Cost of products sold increased 25% from $12,680.1 million for the year ended December 31, 2011 to $15,840.6 million for the 
year ended December 31, 2012, due principally to the inclusion of sales volumes and related cost of products sold at the El Dorado 
and Cheyenne Refineries, partially offset by lower crude oil costs for the current year. The average price we paid per barrel for 
crude oil and feedstocks and the transportation costs of moving the finished products to the market place decreased 4% from 
$98.18 for the year ended December 31, 2011 to $94.59 for the year ended December 31, 2012.

Gross Refinery Margins
Gross refinery margin per produced barrel increased 21% from $20.64 for the year ended December 31, 2011 to $24.89 for the 
year ended December 31, 2012. This is due to the effects of a current year decrease in crude oil and feedstock prices along with 
slightly higher sales prices received on produced products sold. Gross refinery margin does not include the effects of depreciation 
and amortization. See “Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles” following Item 7A 
of Part II of this Form 10-K for a reconciliation to the income statement of prices of refined products sold and cost of products 
purchased.

Operating Expenses
Operating  expenses,  exclusive  of  depreciation  and  amortization,  increased  33%  from  $748.1  million  for  the  year  ended 
December 31, 2011 to $995.0 million for the year ended December 31, 2012, due principally to the inclusion of the legacy Frontier 
refinery operations for a full-year period and higher repair and maintenance and environmental remediation costs. For the current 
year, we increased certain environmental remediation accruals by $46.1 million to reflect revisions to certain cost estimates and 
the timeframe for which certain environmental remediation and monitoring activities are expected to occur. Also contributing to 
a  much  lesser  extent  were  increased  payroll  costs  attributable  to  the  legacy  Holly  refining  operations.  For  the  years  ended 
December 31, 2012 and 2011, operating expenses include $88.9 million and $61.1 million, respectively, in costs attributable to 
HEP operations.

General and Administrative Expenses
General and administrative expenses increased 7% from $120.1 million for the year ended December 31, 2011 to $128.1 million 
for the year ended December 31, 2012, due principally to higher employee benefit and equity-based compensation costs and 
increased corporate staffing levels as a result of our July 1, 2011 merger, net of the effects of merger related severance and integration 
costs incurred during 2011. For the years ended December 31, 2012 and 2011, general and administrative expenses include $5.3 
million and $4.3 million, respectively, in costs attributable to HEP operations.

Depreciation and Amortization Expenses
Depreciation and amortization increased 52% from $159.7 million for the year ended December 31, 2011 to $242.9 million for 
the year ended December 31, 2012. The increase was due principally to depreciation and amortization attributable to the legacy 
Frontier refinery assets, capitalized improvement projects and HEP's UNEV Pipeline. For the years ended December 31, 2012 
and 2011, depreciation and amortization expenses include $57.8 million and $33.3 million, respectively, in costs attributable to 
HEP operations.

38

Table of Content

Interest Income
Interest income for the year ended December 31, 2012 was $4.8 million compared to $1.3 million for the year ended December 31, 
2011. This increase was due to interest received on our increased cash position and investments in marketable debt securities.

Interest Expense
Interest  expense  was  $104.2  million  for  the  year  ended  December 31,  2012  compared  to  $78.3  million  for  the  year  ended 
December 31, 2011. This increase principally reflects interest on the senior notes assumed upon our merger with Frontier. For the 
years ended December 31, 2012 and 2011, interest expense included $57.2 million and $38.2 million, respectively, in interest 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 
on July 1, 2011. These costs included legal, advisory and other professional fees that were directly attributable to the merger. There 
were no such costs incurred for the year ended December 31, 2012.

Income Taxes
For the year ended December 31, 2012, we recorded income tax expense of $1,028.0 million compared to $582.0 million for the 
year ended December 31, 2011. This increase is due principally to significantly higher pre-tax earnings during the year ended 
December 31, 2012 compared to the same period of 2011. Our effective tax rates, before consideration of earnings attributable to 
the noncontrolling interest, were 36.9% and 35.5% for the years ended December 31, 2012 and 2011, respectively. 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.

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 $104.0 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 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 beginning July 1, 2011.  

Sales and Other Revenues
Sales and other revenues 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 2010. 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 $36.0 
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 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.

Table of Content

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 31, 2011 and 2010, operating expenses include 
$61.1 million and $52.7 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 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  $33.3  million  and  $28.9  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 $5.0 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 $36.2 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 
on 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 $582.0 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.

LIQUIDITY AND CAPITAL RESOURCES

HollyFrontier Credit Agreement 
We  have  a  $1  billion  senior  secured  credit  agreement  (the  “HollyFrontier  Credit Agreement”)  with  Union  Bank,  N.A.  as 
administrative agent and certain lenders from time to time party thereto. 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. At December 31, 2012, we were in compliance with all 
covenants, had no outstanding borrowings and had outstanding letters of credit totaling $29.2 million under the HollyFrontier 
Credit Agreement.

HEP Credit Agreement
HEP has a $550 million senior secured revolving credit facility that matures in June 2017 (the “HEP Credit Agreement”) and is 
available  to  fund  capital  expenditures,  investments,  acquisitions,  distribution  payments  and  working  capital  and  for  general 
partnership purposes. It is also available to fund letters of credit up to a $50 million sub-limit and to fund distributions to unitholders 
up to a $60 million sub-limit. At December 31, 2012, HEP was in compliance with all of its covenants, had outstanding borrowings 
of $421.0 million and no outstanding letters of credit under the HEP Credit Agreement.

HEP’s obligations under the HEP Credit Agreement are collateralized by substantially all of HEP’s assets (presented parenthetically 
in our consolidated balance sheets). Indebtedness under the HEP Credit Agreement involves recourse to HEP Logistics Holdings, 
L.P., its general partner, and is guaranteed by HEP’s wholly-owned subsidiaries. Any recourse to the general partner would be 
limited to the extent of HEP Logistics Holdings, L.P.’s assets, which other than its investment in HEP, are not significant. HEP’s 
creditors have no 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 ($286.8 million principal amount maturing June 2017)
6.875% senior notes ($150 million principal amount maturing November 2018) 

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.

In September 2012, we redeemed our $200 million aggregate principal amount of 8.5% senior notes maturing September 2016 at 
a redemption price of $208.5 million.

HollyFrontier Financing Obligation
We have a financing obligation that relates to a sale and lease-back of certain crude oil tankage that we sold to an affiliate of Plains 
All American Pipeline, L.P. (“Plains”) in October 2009 for $40.0 million. Monthly lease payments are recorded as a reduction in 
principal over the 15-year lease term ending in 2024.

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

• 
• 

8.25% HEP senior notes ($150 million principal amount maturing March 2018)
6.5% HEP senior notes ($300 million principal amount maturing March 2020)

In March 2012, HEP issued $300 million in an aggregate principal amount of 6.5% HEP senior notes maturing March 2020. The 
$294.8 million in net proceeds were used to repay $157.8 million aggregate principal amount of 6.25% HEP senior notes, $72.9 
million in promissory notes due to HollyFrontier, related fees, expenses and accrued interest in connection with these transactions 
and to repay borrowings under the HEP Credit Agreement. In April 2012, HEP called for redemption the remaining $27.2 million 
aggregate principal amount outstanding of 6.25% HEP senior notes.

The  8.25%  and  6.5%  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 involves recourse to HEP Logistics Holdings, L.P., its general partner, and is guaranteed 
by HEP’s wholly-owned subsidiaries. However, any recourse to the general partner would be limited to the extent of HEP Logistics 
Holdings, L.P.’s assets, which other than its investment in HEP, are not significant. HEP’s creditors have no other recourse to our 
assets. Furthermore, our creditors have no recourse to the assets of HEP and its consolidated subsidiaries.

Liquidity
We believe our current cash and cash equivalents, along with future internally generated cash flow and funds available under our 
credit facilities will provide sufficient resources to fund currently planned capital projects and our liquidity needs for the foreseeable 
future. In addition, components of our growth strategy include construction of new refinery processing units and the expansion 
of existing units at our facilities and selective acquisition of complementary assets for our refining operations intended to increase 
earnings and cash flow.

As of December 31, 2012, our cash, cash equivalents and investments in marketable securities totaled $2.4 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 financial institutions or government entities with strong credit standings.

In January 2012, our Board of Directors approved a $350 million stock repurchase program, and in June 2012, approved an 
additional $350 million repurchase program that authorizes us to repurchase common stock in the open market or through privately 
negotiated transactions. The timing and amount of stock repurchases will depend on market conditions, corporate, regulatory and 
other relevant considerations. These programs may be discontinued at any time by the Board of Directors. As of December 31, 
2012, we have repurchased 6,775,729 shares at a cost of $205.6 million, with remaining authorization to repurchase $494.4 million 
under these stock repurchase programs.

Cash and cash equivalents increased $178.8 million for the year ended December 31, 2012. Cash provided by operating activities 
of $1,662.7 million exceeded net cash used for investing and financing activities of $711.1 million and $772.8 million, respectively. 
Working capital increased by $785.8 million during the year ended December 31, 2012.

Cash Flows – Operating Activities

Year Ended December 31, 2012 Compared to Year Ended December 31, 2011 
Net cash flows provided by operating activities were $1,662.7 million for the year ended December 31, 2012 compared to $1,338.4 
million for the year ended December 31, 2011, an increase of $324.3 million. Net income for the year ended December 31, 2012 
was $1,760.0 million, an increase of $700.3 million compared to $1,059.7 million for the year ended December 31, 2011. Non-
cash adjustments consisting of depreciation and amortization, gain on sale of equity securities, deferred income taxes, equity-
based compensation expense and fair value changes to derivative instruments resulted in an increase to operating cash flows of 
$429.5 million for the year ended December 31, 2012 compared to $178.0 million for the same period in 2011. Changes in working 
capital items decreased cash flows by $398.0 million for the year ended December 31, 2012 compared to an increase of $147.3 
million for the year ended December 31, 2011. The decrease in working capital items for the year ended December 31, 2012 was 
due principally to higher inventory levels and a decrease in income taxes payable and accrued liabilities due to timing differences 
of payments during the fourth quarter of 2012 relative to 2011. Additionally, for the year ended December 31, 2012, turnaround 
expenditures increased to $159.7 million from $32.0 million for the same period of 2011.

Year Ended December 31, 2011 Compared to Year Ended December 31, 2010
Net cash flows provided by operating activities were $1,338.4 million for the year ended December 31, 2011 compared to $283.3 
million for the year ended December 31, 2010, an increase of $1,055.1 million. Net income for the year ended December 31, 2011 
was  $1,059.7  million,  an  increase  of  $926.6  million  from  $133.1  million  for  the  year  ended  December  31,  2010.  Non-cash 
adjustments consisting of depreciation and amortization, deferred income taxes, equity-based compensation expense and derivative 
instrument adjustments resulted in an increase to operating cash flows of $178.0 million for the year ended December 31, 2011 
compared to $154.3 million for the year ended December 31, 2010. Changes in working capital items increased cash flows by 
$147.3 million in 2011 compared to $24.7 million in 2010. The increase in working capital items for the year ended December 
31, 2011 was due principally to the effects of higher levels of accrued liabilities at December 31, 2011 relative to 2010 as a result 
of increased income taxes and costs supporting our recently merged company. Additionally, turnaround expenditures were $32.0 
million and $35.0 million for the years ended December 31, 2011 and 2010, respectively.

Cash Flows – Investing Activities and Planned Capital Expenditures

Year Ended December 31, 2012 Compared to Year Ended December 31, 2011 
Net cash flows used for investing activities were $711.1 million for the year ended December 31, 2012 compared to net cash flows 
provided by investing activities of $228.5 million for the year ended December 31, 2011, a decrease of $939.6 million. Investing 
activities for 2011 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, plants and equipment for 2012 decreased to $335.3 million from 
$374.2 million for the same period in 2011. These include HEP capital expenditures of $44.9 million and $216.2 million for the 
years ended December 31, 2012 and 2011, respectively, which include 2011 capital expenditures of $164.3 million to construct 
the UNEV Pipeline. Also for the years ended December 31, 2012 and 2011, we invested $671.6 million and $561.9 million, 
respectively, in marketable securities and received proceeds of $297.7 million and $301.0 million, respectively, from the sale or 
maturity of marketable securities.

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. Investing 
activities for 2011 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 $216.2 million and $109.5 million for the years ended 
December 31, 2011 and 2010, respectively. 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 $301.0 million from the sale of our marketable securities.

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 2013 is $320.0 million including both sustaining capital and major capital projects. 
We expect to spend approximately $400.0 million to $450.0 million in cash for capital projects appropriated in 2013 plus those 
appropriated in prior years but not yet completed. In addition, we expect to spend $156.0 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 2013 and expected cash spending is 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 FCC unit flue gas scrubbers and tail gas treatment units), federal 
fuels regulations (particularly, MSAT2 which mandates a reduction in the benzene content of blended gasoline), refinery waste 
water treatment improvements and other similar initiatives. Our refinery operations and related emissions are highly regulated at 
both federal and state levels, and we invest in our facilities as needed to remain in compliance with these standards. Additionally, 
when faced with new emissions or fuels standards, we seek to execute projects that facilitate compliance and also improve the 
operating costs and/or yields of associated refining processes. 

El Dorado Refinery
Newly appropriated capital projects at the El Dorado Refinery include naphtha fractionation, an additional hydrogen plant and a 
Low-Nox addition to the FCC unit flue gas scrubber. Continuing project work will include coke drum pressure reduction designed 
to improve liquid yields and a new tail gas treatment unit to reduce air emissions in compliance with the El Dorado Refinery's 
existing EPA consent decree.

Tulsa Refineries
New 2013 appropriations for the Tulsa Refineries include a gasoline-blending system and numerous infrastructure upgrades. We 
will continue spending on the conversion of our propane de-asphalt unit to ROSE technology and on our sulfur recovery project 
related to the refinery fuel gas system. This project will be completed in approximately the second quarter of 2013 and, in addition 
to facilitating compliance with our EPA consent, will also allow us to increase use of lower priced sour / heavy crude in Tulsa. 
Spending on maintenance capital items and general improvements continues at an elevated level at the Tulsa Refineries due to 
perceived opportunities.

Navajo Refinery
The  Navajo  Refinery  capital  spending  in  2013  will  be  principally  on  previously  approved  capital  appropriations  as  well  as 
maintenance capital spending. Included among previously approved capital projects is a $25.0 million upgrade to the Navajo 
Refinery's waste water treatment system.

Cheyenne Refinery
We plan to install a new hydrogen plant at the Cheyenne Refinery and have appropriated this capital project as part of our 2013 
budget. The hydrogen plant, along with a previously approved naphtha fractionation project, will allow us to reduce benzene 
content in Cheyenne gasoline production, while at the same time improving the refinery's overall liquid yields and light oils 
production. Previously appropriated projects still underway at Cheyenne include wastewater treatment plant improvements, a wet 
gas scrubber for the FCC unit to reduce air emissions, a redundant tail gas unit associated with sulfur recovery processes and 
additional investment in the waste water treatment plant to reduce selenium concentration in waste water.

Woods Cross Refinery
Newly appropriated capital for the Woods Cross Refinery consists of warehouse and office relocations to accommodate the refinery 
expansion and modernization program and of a new rail loading rack for intermediates and finished products associated with 
refining waxy crude oil. We continue to work on the $225.0 million refinery expansion project announced previously, with expected 
completion date in approximately the fourth quarter of 2014.

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

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 2013 HEP capital budget is comprised of $9.2 
million for maintenance capital expenditures and $2.3 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. HEP has a second project recently approved which consists of the reactivation and conversion to crude 
oil service of a 70-mile, 8-inch petroleum products pipeline owned by HEP. This project also includes the expansion and extension 
of several of HEP's crude gathering systems and crude mainline pipes. Once in service, this system will be capable of transporting 
crude oil from southeast New Mexico to third-party common carrier pipelines in west Texas for further transport to major crude 
oil markets. This project is estimated to cost approximately $38.0 million and could be fully operational in late 2013.

Cash Flows – Financing Activities

Year Ended December 31, 2012 Compared to Year Ended December 31, 2011 
Net cash flows used for financing activities were $772.8 million for the year ended December 31, 2012 compared to $217.1 million 
for the year ended December 31, 2011, an increase of $555.7 million. During the year ended December 31, 2012, we purchased 
$209.6 million in common stock, paid $658.1 million in dividends, paid $205.0 million in principal on our senior notes and

were $6.0 million and $33.5 million, respectively.

Year Ended December 31, 2011 Compared to Year Ended December 31, 2010
Net cash flows used for 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, 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 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 common units,

noncontrolling interests and purchased $1.6 million in HEP common units in the open market for recipients of its restricted unit 
grants. Additionally, $11.8 million in deferred financing costs were incurred in connection with the amendment of HEP's credit 
facility in February 2011 and a revision to the HollyFrontier Credit Agreement upon the merger with Frontier. During 2010, we 
received and repaid $310.0 million in advances under the HollyFrontier Credit Agreement, paid $31.9 million in dividends and 
recognized $1.1 million excess tax benefits on our equity based compensation. Also during this period, HEP received $147.5 
million in net proceeds upon the issuance of the HEP 8.25% senior notes, received $66.0 million and repaid $113.0 million under 
the HEP Credit Agreement, paid distributions of $48.5 million to noncontrolling interests and purchased $2.7 million in HEP 
common units in the open market for recipients of its restricted unit grants. Additionally, $3.1 million in deferred financing costs 
were incurred in connection with the issuance of the HEP 8.25% senior notes in March 2010 and an amendment to the HollyFrontier 
Credit Agreement. UNEV Pipeline joint venture partner contributions received during the years ended December 31, 2011 and 
2010 were $33.5 million and $23.5 million, respectively.

(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 $12.6 million as of December 31, 2012 have been excluded from 
the contractual obligations table above. For further information related to unrecognized tax benefits, see Note 15 “Income Taxes” in the Notes to 
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. 

(3)  Our long-term debt consists of the $286.8 million principal balance on our 9.875% senior notes, the $150.0 million principal balance on our 6.875% 

senior notes and a long-term financing obligation having a principal balance of $36.3 million at December 31, 2012.
Interest payments consist of interest on our 9.875% and 6.875% senior notes and on our long-term financing obligation. 

(4) 
(5)  We have long-term supply agreements to secure certain quantities of crude oil, feedstock and other resources used in the production process at 
market prices. We have estimated future payments under these fixed-quantity agreements expiring between 2014 and 2024 using current market 
rates.

(6)  Consists of contractual obligations under agreements with third parties for the transportation of crude oil, natural gas and feedstocks to our refineries 

and for terminal and storage services under contracts expiring between 2013 and 2024.

(7)  HEP's long-term debt consists of the $150.0 million and the $300.0 million principal balances on the 8.25% and 6.5% HEP senior notes and $421.0

million of outstanding borrowings under the HEP Credit Agreement. The HEP Credit Agreement was amended in June 2012 and expires in 2017.
Interest payments consist of interest on the 6.5% and 8.25% HEP senior notes and interest on long-term debt under the HEP Credit Agreement. The 
interest rate on the HEP Credit Agreement debt was 2.46% at December 31, 2012.

CRITICAL ACCOUNTING POLICIES

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, 
which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of 
these financial statements requires us to  make  estimates and judgments that affect the reported amounts of assets, liabilities, 
revenues and expenses, and related disclosure of contingent assets and liabilities as of the date of the financial statements. Actual 
results may differ from these estimates under different assumptions or conditions. We consider the following policies to be the 
most critical to understanding the judgments that are involved and the uncertainties that could impact our results of operations, 
financial condition and cash flows. For additional information, see Note 1 “Description of Business and Summary of Significant 
Accounting Policies” in the Notes to Consolidated Financial Statements.

Table of Content

In the first quarter of 2012, we changed our policy of reporting certain same-party accounts receivable and payable amounts in 
the consolidated balance sheets to reflect a net amount due under contractual netting agreements. Prior to this change, we reported 
such amounts on a gross basis with a same-party receivable and payable balance presented separately in our balance sheet. GAAP 
permits a reporting entity to elect a policy of offsetting same party receivables and payables when such amounts are net settled 
under legally enforceable contractual setoff provisions. We believe that a net presentation is preferable because it more appropriately 
presents our economic resources (accounts receivable) and claims against us (accounts payable) and the future cash flows associated 
with such assets and liabilities. Additionally, we believe a net presentation of such amounts conforms to the predominant practices 
used by others in our industry. We have applied this change in accounting principle on a retrospective basis and have recast our 
prior period financial statements. See Note 2 “Change in Accounting Policy” in the Notes to Consolidated Financial Statements 
for a summary of line items affected in our financial statements.

Variable Interest Entity
HEP is a VIE as defined under GAAP. A VIE is a legal entity whose equity owners do not have sufficient equity at risk for the 
entity to finance its activities without additional subordinated financial support or, as a group, the equity holders lack the power, 
through voting rights, to direct the activities that most significantly impact the entity's financial performance, the obligation to 
absorb the entity's expected losses or rights to expected residual returns. As the general partner of HEP, we have the sole ability 
to direct the activities of HEP that most significantly impact HEP's 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.

Derivative Instruments
We have commodity price swap, interest rate swap, physical and NYMEX futures contracts that are measured at fair value and 
recognized as other assets or liabilities in our consolidated balance sheets. Changes in fair value to derivative instruments are 
recognized in earnings unless specific hedge accounting criteria is met. Derivatives meeting certain hedge accounting criteria are 
designated as “accounting hedges” and changes in fair value are recorded directly to other comprehensive income. These gains 
or losses are reclassified to earnings as the hedging instruments mature. Also, on a quarterly basis, hedge ineffectiveness on our 
accounting hedges is measured by comparing the change in fair value of the derivative contracts against the expected future cash 
inflows/outflows on the respective transaction being hedged. Any hedge ineffectiveness is recognized in earnings. See Note 14 
“Derivative Instruments and Hedging Activities” in the Notes to Consolidated Financial Statements.

Inventory Valuation 
Our crude oil and refined product inventories are stated at the lower of cost or market. Cost is determined using the LIFO inventory 
valuation methodology and market is determined using current 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, 2012, 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, 2012, the excess of current cost over the LIFO inventory value of our crude oil and refined product inventories was 
$134.0 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 often 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.

Table of Content

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, which is generally determined under an income approach using forecasted cash flows associated with the 
underlying asset. Estimates of future cash flows require subjective assumptions with regard to future operating results and actual 
results could differ from those estimates. No impairments of long-lived assets were recorded during the years ended December 31, 
2012, 2011 and 2010.

Intangibles and Goodwill
Intangible assets are assets (other than financial assets) that lack physical substance. Goodwill represents the excess of the cost 
of an acquired entity over the fair value of the assets acquired less liabilities assumed. Goodwill acquired in a business combination 
and intangible assets with indefinite useful lives are not amortized while intangible assets with finite useful lives are amortized 
on a straight-line basis. Goodwill and intangible assets not subject to amortization are tested for impairment annually or more 
frequently if events or changes in circumstances indicate the asset might be impaired. Our analysis entails a comparison of the 
estimated fair value of these assets that are derived using a combination of both income (discounted future expected net cash 
flows) and comparable market approaches against their respective carrying values. Estimates of future cash flows and fair value 
of assets require subjective assumptions with regard to future operating results and actual results could differ from those estimates. 
There were no impairments of intangible assets or goodwill during the years ended December 31, 2012, 2011 and 2010.

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

RISK MANAGEMENT

We use certain strategies to reduce some commodity price and operational risks. We do not attempt to eliminate all market risk 
exposures when we believe that the exposure relating to such risk would not be significant to our future earnings, financial position, 
capital resources or liquidity or that the cost of eliminating the exposure would outweigh the benefit.

Commodity Price Risk Management
Our primary market risk is commodity price risk. We are exposed to market risks related to the volatility in crude oil and refined 
products, as well as volatility in the price of natural gas used in our refining operations. We periodically enter into derivative 
contracts in the form of commodity price swaps and futures contracts to mitigate price exposure with respect to:

• 
• 
• 
• 
• 

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

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

As of December 31, 2012, HEP had three interest rate swap contracts that hedge its exposure to the cash flow risk caused by the 
effects of LIBOR changes on $305.0 million in credit agreement advances. The first interest rate swap effectively converts $155.0 
million  of  LIBOR  based  debt  to  fixed  rate  debt  having  an  interest  rate  of  0.99%  plus  an  applicable  margin  of  2.25%  as  of 
December 31, 2012, which equaled an effective interest rate of 3.24%. This swap matures in February 2016. HEP has two additional 
interest rate swaps with identical terms which effectively convert $150.0 million of LIBOR based debt to fixed rate debt having 
an interest rate of 0.74% plus an applicable margin of 2.25% as of December 31, 2012, which equaled an effective interest rate 
of 2.99%. Both of these swap contracts mature in July 2017. These swap contracts have been designated as cash flow hedges.

The market risk inherent in our fixed-rate debt 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, 2012 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, 
2012, outstanding borrowings under the HEP Credit Agreement were $421.0 million. By means of its cash flow hedges, HEP has 
effectively converted the variable rate on $305.0 million of outstanding principal to a weighted average fixed rate of 3.12%.  

At  December 31,  2012,  our  marketable  securities  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 hazards of petroleum processing operations, including fire, explosion and weather-related perils. We 
maintain various insurance coverages, including business interruption insurance, subject to certain deductibles. We are not fully 
insured against certain risks because such risks are not fully insurable, coverage is unavailable, or premium costs, in our judgment, 
do not justify such expenditures.

Financial information is reviewed on the counterparties in order to review and monitor their financial stability and assess their 
ongoing ability to honor their commitments under the derivative contracts. We have not experienced, nor do we expect to experience, 
any difficulty in the counterparties honoring their commitments.

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

Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles

Reconciliations  of  earnings  before  interest,  taxes,  depreciation  and  amortization  (“EBITDA”)  to  amounts  reported  under 
generally accepted accounting principles in financial statements.

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

Set forth below is our calculation of EBITDA.

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

Refinery gross margin and net operating margin are non-GAAP performance measures that are used by our management and others 
to compare our refining performance to that of other companies in our industry. We believe these margin measures are helpful to 
investors in evaluating our refining performance on a relative and absolute basis.

Refinery gross margin per 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.

Refinery Gross and Net Operating Margins

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

Item 8.  Financial Statements and Supplementary Data

MANAGEMENT'S REPORT ON ITS ASSESSMENT OF THE COMPANY'S INTERNAL CONTROL OVER 
FINANCIAL REPORTING

Management of HollyFrontier Corporation (the “Company”) is responsible for establishing and maintaining adequate internal 
control over financial reporting.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined 
to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Management assessed the Company's internal control over financial reporting as of December 31, 2012 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, 
2012, 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, 2012. That report appears on page 55.

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, 2012, 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 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, 2012, 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,  2012  and  2011,  and  the  related  consolidated 
statements of income, comprehensive income, cash flows and equity for each of the three years in the period ended December 31, 
2012 and our report dated February 27, 2013 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, 
2012 and 2011, and the related consolidated statements of income, comprehensive income, cash flows and equity for each of the 
three years in the period ended December 31, 2012. 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, 2012 and 2011, and the consolidated results of its operations and its cash flows for 
each of the three years in the period ended December 31, 2012, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 2 to the consolidated financial statements, the Company has elected to change its method of accounting for 
accounts receivables and payables with the same counterparty where a right of setoff exists from a gross presentation to a net 
presentation in the consolidated balance sheets.

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, 2012, 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 27, 2013 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 Holly Energy Partners, L.P. 
(“HEP”) and its subsidiaries as consolidated subsidiaries of HollyFrontier, unless when used in disclosures of transactions or 
obligations between HEP and HollyFrontier or its other subsidiaries. These financial statements contain certain disclosures of 
agreements that are specific to HEP and its consolidated subsidiaries and do not necessarily represent obligations of HollyFrontier. 
When used in descriptions of agreements and transactions, “HEP” refers to HEP and its consolidated subsidiaries.

We merged with Frontier Oil Corporation (“Frontier”) on 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 3). 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 petroleum refineries that serve markets 
throughout the Mid-Continent, Southwest and Rocky Mountain regions of the United States. As of December 31, 2012, 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 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 44% interest in HEP, a consolidated variable interest entity (“VIE”), which includes our 2% general partner 
interest. HEP owns and operates logistic assets consisting of petroleum product and crude oil pipelines and terminal, 
tankage and loading rack facilities that principally support our refining and marketing operations in the Mid-Continent, 
Southwest and Rocky Mountain regions of the United States and Alon USA, Inc.'s (“Alon”) refinery in Big Spring, Texas. 
Additionally, HEP owns a 75% interest in UNEV Pipeline, L.L.C. (“UNEV”), which owns a 12-inch refined products 
pipeline from Salt Lake City, Utah to Las Vegas, Nevada, together with terminal facilities in the Cedar City, Utah and 
North Las Vegas areas (the “UNEV Pipeline”) and a 25% interest in SLC Pipeline LLC (the “SLC Pipeline”), a 95-mile 
intrastate pipeline system that serves refineries in the Salt Lake City area.

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

Variable Interest 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 for the entity to finance its activities without additional subordinated 
financial support or, as a group, the equity holders lack the power, through voting rights, to direct the activities that most significantly 
impact the entity's financial performance, the obligation to absorb the entity's expected losses or rights to expected residual returns. 
As the general partner of HEP, we have the sole ability to direct the activities of HEP that most significantly impact HEP's 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 upon reconsolidation 
in 2008 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 consist of certificates of deposit, commercial paper, corporate debt securities 
and government and municipal debt securities with the maximum maturity or put date of any individual issue generally not more 
than two years, while the maximum duration of the portfolio of investments is not greater than one year. These instruments are 
classified as available-for-sale, and as a result, are reported at fair value. Unrealized gains and losses, net of related income taxes, 
are reported as a component of accumulated other comprehensive income.

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 $2.5 million and $3.5 million at December 31, 2012 and 2011, 
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 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, which is 
generally determined under an income approach using the forecasted cash flows associated with the underlying asset. Estimates 
of future cash flows require subjective assumptions with regard to future operating results and actual results could differ from 
those estimates. No impairments of long-lived assets were recorded during the years ended December 31, 2012, 2011 and 2010.

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.

Our asset retirement obligations were $18.1 million and $14.4 million at December 31, 2012 and 2011, respectively, which are 
included in “Other long-term liabilities” in our consolidated balance sheets. Accretion expense was insignificant for the years 
ended December 31, 2012, 2011 and 2010. 

Intangibles and Goodwill:  Intangible assets are assets (other than financial assets) that lack physical substance. Goodwill represents 
the excess of the cost of an acquired entity over the fair value of the assets acquired less liabilities assumed. Goodwill acquired in 
a business combination and intangible assets with indefinite useful lives are not amortized while, intangible assets with finite useful 
lives are amortized on a straight-line basis. Goodwill and intangible assets not subject to amortization are tested for impairment 
annually or more frequently if events or changes in circumstances indicate the asset might be impaired. Our analysis entails a 
comparison of the estimated fair value of these assets that are derived using a combination of both income (discounted future 
expected net cash flows) and comparable market approaches against their respective carrying values. Estimates of future cash 
flows and fair value of assets require subjective assumptions with regard to future operating results and actual results could differ 
from those estimates.

In  addition  to  goodwill,  our  consolidated  HEP  assets  include  a  third-party  transportation  agreement  that  currently  generates 
minimum annual cash inflows of $24.4 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 $2.0 million. The balance 
of this transportation agreement was $44.5 million and $46.5 million at December 31, 2012 and 2011, respectively, and is presented 
net of accumulated amortization of $15.7 million and $13.7 million, respectively, in “Intangibles and other” in our consolidated 
balance sheets. There were no impairments of intangible assets or goodwill during the years ended December 31, 2012, 2011 and 
2010.

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, 2012, HEP's underlying equity in the SLC Pipeline was $60.0 million compared to its recorded investment balance 
of $25.0 million, a difference of $35.0 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 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.

NOTE 2:  Change in Accounting Principle

In the first quarter of 2012, we changed our policy of reporting certain same-party accounts receivable and payable balances in 
the consolidated balance sheets to reflect a net amount due under contractual netting agreements. Prior to this change, we reported 
such balances on a gross basis with a same-party receivable and payable balance presented separately in our balance sheet. GAAP 
permits a reporting entity to elect a policy of offsetting same-party receivables and payables when such amounts are net settled 
under legally enforceable contractual setoff provisions. We believe that a net presentation is preferable because it more appropriately 
presents our economic resources (accounts receivable) and claims against us (accounts payable) and the future cash flows associated 
with such assets and liabilities. Additionally, we believe a net presentation of such amounts conforms to the predominant practices 
used by other companies in our industry. We have applied this change in accounting principle on a retrospective basis and have 
recast our prior period financial statements.

The following table summarizes the line items affected in our consolidated balance sheet at December 31, 2011:

At December 31, 2012, our accounts payable balance is presented net of $723.4 million in crude oil receivables subject to contractual

earnings.

NOTE 3:  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. 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 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  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 consideration paid in connection with the merger was approximately $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. 

Our consolidated financial and operating results reflect the operations of the merged Frontier businesses beginning July 1, 2011, 
which consists of crude oil refining and the wholesale marketing of refined petroleum products produced at the El Dorado and 
Cheyenne Refineries, which serve markets in the Rocky Mountain and Plains States regions of the United States. 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:

For the year ended December 31, 2011, we 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 included $26.5 million in integration and severance costs associated 
with the merger integration.

NOTE 4:  Holly Energy Partners

HEP, a consolidated VIE, is a publicly held master limited partnership that was formed to acquire, own and operate the petroleum 
product and crude oil pipeline and terminal, tankage and loading rack facilities that support our refining and marketing operations 
in the Mid-Continent, Southwest and Rocky Mountain regions of the United States. HEP also owns and operates refined product 
pipelines and terminals, located primarily in Texas, that serve Alon's refinery in Big Spring, Texas.

As of December 31, 2012, we owned a 44% 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 accounted for 84% of HEP’s total revenues for the year ended December 31, 2012. We do not provide financial or 
equity support through any liquidity arrangements and / or debt guarantees to HEP.

HEP has outstanding debt under a senior secured revolving credit agreement and its senior notes. With the exception of the assets 
of HEP Logistics Holdings, L.P., one of our wholly-owned subsidiaries and HEP’s general partner, HEP’s creditors have no recourse 
to our 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, 2012, we have an agreement to pledge up to 6.0 million 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 customer of HEP were to terminate its contracts or fail to meet desired 
shipping or throughput levels for an extended period of time, revenue would be reduced and HEP could suffer substantial losses 
to the extent that a new customer is not found. In the event that HEP incurs a loss, our operating results will reflect HEP’s loss, 
net of intercompany eliminations, to the extent of our ownership interest in HEP at that point in time.

2012 Acquisition

UNEV Interest Transaction
On July 12, 2012, HEP acquired from us our 75% interest in UNEV. We received consideration consisting of $260.0 million in 
cash and 1.0 million HEP common units. As a result of this transaction, our ownership interest in HEP increased to 44%, which 
includes the 2% general partner interest. We have a 10-year transportation agreement with the UNEV Pipeline expiring in 2022 
that results in minimum annualized payments to UNEV of $16.9 million.

We accounted for this transaction as a business transfer between entities under common control, whereby we have retrospectively 
adjusted HEP financial information for all prior periods presented as if UNEV was a consolidated subsidiary of HEP since inception. 
This had no impact on our consolidated balances and amounts; however, it did affect certain amounts presented under the HEP 
segment in Note 21, “Segment Information” and Note 22, “Supplemental Guarantor/Non-Guarantor Financial Information.”

2011 Acquisition

HOLLYFRONTIER CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Continued

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 $150.0 million and 3.8 million HEP common units. 

2010 Acquisitions

Tulsa East / Lovington Storage Asset Transaction
On March 31, 2010, HEP acquired from us certain storage assets for $93.0 million, consisting of hydrocarbon storage tanks having 
approximately 2.0 million barrels of storage capacity, a rail loading rack and a truck unloading rack located at our Tulsa East 
facility and an asphalt loading rack facility located at our Navajo Refinery facility located in Lovington, New Mexico.

Transportation Agreements
HEP serves our refineries under long-term pipeline and terminal, tankage and throughput agreements expiring from 2019 through 
2026. Under these agreements, we pay HEP fees to transport, store and throughput volumes of refined product and crude oil on 
HEP's pipeline and terminal, tankage and loading rack facilities that result in minimum annual payments to HEP including UNEV 
(a consolidated subsidiary of HEP). Under these agreements, the agreed upon tariff rates are subject to annual tariff rate adjustments 
on July 1 at a rate based upon the percentage change in Producer Price Index (“PPI”) or Federal Energy Regulatory Commission 
(“FERC”) index. As of December 31, 2012, these agreements result in minimum annualized payments to HEP of $217.2 million.

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

HEP Common Unit Issuances

2012 Issuances
In July 2012, HEP issued 1.0 million of its common units to us as partial consideration for its purchase of our 75% interest in 
UNEV.

2011 Issuances
In December 2011, HEP issued 1.5 million 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 3.8 million 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  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.

NOTE 5: 

Financial Instruments

Our financial instruments consist of cash and cash equivalents, investments in marketable securities, accounts receivable, accounts 
payable, debt and derivative instruments. The carrying amounts of cash and cash equivalents, accounts receivable and accounts 
payable approximate fair value. HEP's outstanding credit agreement borrowings approximate fair value as interest rates are reset 
frequently at current interest rates.

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

• 

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

• 

• 

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

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

The carrying amounts and estimated fair values of our investments in marketable securities, derivative instruments and the senior 
notes at December 31, 2012 and December 31, 2011 were as follows:

Level 1 Financial Instruments

Level 2 Financial Instruments
Investments in marketable debt securities and derivative instruments consisting of commodity price swaps and HEP's interest rate 
swaps are measured and recorded at fair value using Level 2 inputs. 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 swaps. The fair value of the marketable debt securities and senior notes is based on values 
provided by a third party, which were derived using market quotes for similar type instruments, a Level 2 input. 

Level 3 Financial Instruments
We have commodity price swap contracts that relate to forecasted sales of diesel and unleaded gasoline and forecasted purchases 
of WCS 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 and grade 
differentials, a Level 3 input. 

The following table presents the changes in fair value of our Level 3 assets and liabilities (all related to commodity price swap 
contracts) for the year ended December 31, 2012:

NOTE 6:  Earnings Per Share

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

NOTE 7: 

Stock-Based Compensation

As of December 31, 2012, we have two principal share-based compensation plans including the Frontier plan that was retained 
upon the July 1, 2011 merger (collectively, the “Long-Term Incentive Compensation Plan”). 

The compensation cost charged against income for these plans was $36.3 million, $24.7 million and $9.3 million for the years 
ended December 31, 2012, 2011 and 2010, respectively. Our accounting policy for the recognition of compensation expense for 
awards with pro-rata vesting (substantially all of our awards) is to expense the costs ratably over the vesting periods.

Additionally,  HEP  maintains  a  share-based  compensation  plan  for  HEP  directors  and  select  Holly  Logistic  Services,  L.L.C. 
executives and employees. Compensation cost attributable to HEP’s share-based compensation plan was $2.7 million, $2.1 million 
and $2.2 million for the years ended December 31, 2012, 2011 and 2010, 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 most awards vesting over a period of one to three years. Although ownership of the shares does not 
transfer to the recipients until 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.

For the year ended December 31, 2012, we issued 1,035,025 shares of our common stock upon the vesting of restricted stock 
grants having a grant date fair value of $27.7 million. As of December 31, 2012, there was $17.4 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 1.7 years.

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

The fair value of performance share unit awards subject to financial performance criteria is computed using 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, 2012, estimated share payouts for outstanding non-vested performance 
share unit awards ranged approximately from 110% to 180%.

For the performance share units subject to market performance criteria, performance 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 valued using a Monte Carlo valuation 
model, which simulates future stock price movements using key inputs including grant date stock prices, expected stock price 
performance, expected rate of return and volatility. These units are payable in stock based on share price performance relative to 
the defined peer group and can range from zero to 200% of the initial target award.

A summary of performance share unit activity and changes during the year ended December 31, 2012 is presented below:

For the year ended December 31, 2012, we issued 869,231 shares of our common stock, representing a 192% payout on vested 
performance share units having a grant date fair value of $6.0 million. Based on the weighted-average grant date fair value of 
$35.38 per share, there was $26.7 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 1.8 years.

NOTE 8:  Cash and Cash Equivalents and Investments in Marketable Securities

Our investment portfolio at December 31, 2012 consisted of cash, cash equivalents and investments in marketable debt securities.

We invest in highly-rated marketable debt securities 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, which are usually held until maturity. All of these instruments are classified as available-
for-sale. As a result, they are reported at fair value using quoted market prices. Interest income is recorded as earned. Unrealized 
gains and losses, net of related income taxes, are reported as a component of accumulated other comprehensive income. Upon sale 
or maturity, realized gains on our marketable debt securities are recognized as interest income. These gains are computed based 
on the specific identification of the underlying cost of the securities, net of unrealized gains and losses previously reported in other 
comprehensive income.

The following is a summary of our available-for-sale securities:

We expensed $46.1 million, $14.0 million and $(0.6) million for the years ended December 31, 2012, 2011 and 2010, respectively, 
for environmental remediation obligations. In 2012, we increased certain environmental cost accruals to reflect revisions to certain 
cost estimates and the timeframe for which certain environmental remediation and monitoring activities are expected to occur. 
The  accrued  environmental  liability  reflected  in  our  consolidated  balance  sheets  was  $88.9  million  and  $42.2  million  at 
December 31, 2012 and 2011, respectively, of which $72.6 million and $31.7 million, respectively, were classified as other long-
term liabilities. These accruals include remediation and monitoring costs expected to be incurred over an extended period of time 
(up to 30 years for certain projects). They also include $15.6 million in environmental liabilities that were assumed upon our 
merger with Frontier in 2011. 

NOTE 13:  Debt

HollyFrontier Credit Agreement
We  have  a  $1  billion  senior  secured  credit  agreement  (the  “HollyFrontier  Credit Agreement”)  with  Union  Bank,  N.A.  as 
administrative agent and certain lenders from time to time party thereto. 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. At December 31, 2012, we were in compliance with all 
covenants, had no outstanding borrowings and had outstanding letters of credit totaling $29.2 million under the HollyFrontier 
Credit Agreement. 

HEP Credit Agreement
HEP has a $550 million senior secured revolving credit facility that matures in June 2017 (the “HEP Credit Agreement”) and is 
available  to  fund  capital  expenditures,  investments,  acquisitions,  distribution  payments  and  working  capital  and  for  general 
partnership purposes. It is also available to fund letters of credit up to a $50 million sub-limit and to fund distributions to unitholders 
up to a $60 million sub-limit. At December 31, 2012, HEP was in compliance with all its covenants, had outstanding borrowings 
of $421.0 million and no outstanding letters of credit under the HEP Credit Agreement.

HEP’s obligations under the HEP Credit Agreement are collateralized by substantially all of HEP’s assets (presented parenthetically 
in our consolidated balance sheets). Indebtedness under the HEP Credit Agreement involves recourse to HEP Logistics Holdings, 
L.P., its general partner, and is guaranteed by HEP’s wholly-owned subsidiaries. Any recourse to the general partner would be 
limited to the extent of HEP Logistics Holdings, L.P.’s assets, which other than its investment in HEP, are not significant. HEP’s 
creditors have no 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 ($286.8 million principal amount maturing June 2017)
6.875% senior notes ($150 million principal amount maturing November 2018) 

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.

In September 2012, we redeemed our $200 million aggregate principal amount of 8.5% senior notes maturing September 2016 at 
a redemption price of $208.5 million.

HollyFrontier Financing Obligation
We have a financing obligation that relates to a sale and lease-back of certain crude oil tankage that we sold to an affiliate of Plains 
All American Pipeline, L.P. (“Plains”) in October 2009 for $40.0 million. Monthly lease payments are recorded as a reduction in 
principal over the 15-year lease term ending in 2024.

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

• 
• 

8.25% HEP senior notes ($150 million principal amount maturing March 2018)
6.5% HEP senior notes ($300 million principal amount maturing March 2020)

In March 2012, HEP issued $300 million in an aggregate principal amount of 6.5% HEP senior notes maturing March 2020. The 
$294.8 million in net proceeds were used to repay $157.8 million aggregate principal amount of 6.25% HEP senior notes, $72.9 
million in promissory notes due to HollyFrontier, related fees, expenses and accrued interest in connection with these transactions 
and to repay borrowings under the HEP Credit Agreement. In April 2012, HEP called for redemption the remaining $27.2 million 
aggregate principal amount outstanding of 6.25% HEP senior notes.

The  8.25%  and  6.5%  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 involves recourse to HEP Logistics Holdings, L.P., its general partner, and is guaranteed 
by HEP’s wholly-owned subsidiaries. However, any recourse to the general partner would be limited to the extent of HEP Logistics 
Holdings, L.P.’s assets, which other than its investment in HEP, are not significant. HEP’s creditors have no 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.

Accounting Hedges
We have swap contracts serving as cash flow hedges against price risk on forecasted purchases of natural gas and WTI crude oil 
and  forecasted  sales  of  ultra-low  sulfur  diesel  and  conventional  unleaded  gasoline. 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 to earnings as the hedging instruments mature. Also on 
a quarterly basis, hedge ineffectiveness is measured by comparing the change in fair value of the swap contracts against the expected 
future cash inflows/outflows on the respective transaction being hedged. Any hedge ineffectiveness is also recognized in earnings.

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

Economic Hedges
We also have swap contracts that serve as economic hedges (derivatives used for risk management, but not designated as accounting 
hedges) to fix our purchase price on forecasted crude oil and other feedstock purchases, and to lock in the spread between WCS 
and WTI crude oil on forecasted WCS purchases. Also, we have NYMEX futures contracts to lock in prices on purchases of 
inventory. These contracts are measured quarterly at fair value with offsetting adjustments (gains/losses) recorded directly to 
income.

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

As of December 31, 2012, HEP had three interest rate swap contracts that hedge its exposure to the cash flow risk caused by the 
effects of LIBOR changes on $305.0 million in credit agreement advances. The first interest rate swap effectively converts $155.0 
million  of  LIBOR  based  debt  to  fixed  rate  debt  having  an  interest  rate  of  0.99%  plus  an  applicable  margin  of  2.25%  as  of 
December 31, 2012, which equaled an effective interest rate of 3.24%. This swap matures in February 2016. HEP has two additional 
interest rate swaps with identical terms which effectively convert $150.0 million of LIBOR based debt to fixed rate debt having 
an interest rate of 0.74% plus an applicable margin of 2.25% as of December 31, 2012, which equaled an effective interest rate of 
2.99%. Both of these swap contracts mature in July 2017. All of these swap contracts have been designated as cash flow hedges. 
To date, there has been no ineffectiveness on these cash flow hedges.

At December 31, 2012, HEP had a pre-tax unrealized loss recorded in accumulated other comprehensive income of $4.3 million 
that relates to its current and previous cash flow hedging instruments. Of this amount, $0.8 million relates to a 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.

At December 31, 2012, we had a pre-tax net unrealized loss of $23.3 million classified in accumulated other comprehensive income 
that relates to all accounting hedges. Assuming commodity prices and interest rates remain unchanged, an  unrealized loss  of 
approximately $11.7 million will be effectively transferred from accumulated other comprehensive income into the statement of 
income as the hedging instruments mature over the next twelve-month period.

At December 31, 2012, we had a net operating loss carryforward of $46.5 million in the state of Colorado that is scheduled to be 
utilized in 2013 through 2029 and a Kansas income tax credit of $15.8 million that is scheduled to be utilized in 2013 through 
2019. These amounts are reflected in other current and non-current deferred tax assets.

As of December 31, 2012, the total amount of unrecognized tax benefits was $12.6 million. A reconciliation of the beginning and 
ending amount of unrecognized tax benefits is as follows:

Balance at January 1
Additions due to merger with Frontier
Additions for tax positions of prior years

At December 31, 2012, 2011 and 2010, there are $10.2 million, $2.2 million and $1.1 million, respectively, of unrecognized tax 
benefits that, if recognized, would affect our effective tax rate. Unrecognized tax benefits are adjusted in the period in which new 
information about a tax position becomes available or the final outcome differs from the amount recorded.

We recognize interest and penalties relating to liabilities for unrecognized tax benefits as an element of tax expense. We have not 
recorded any penalties related to our uncertain tax positions as we believe that it is more likely than not that there will not be any 
assessment of penalties. We expect that unrecognized tax benefits for tax positions taken with respect to 2012 and prior years will 
change within the next 12 months and the majority of these items will be settled with taxing authorities.

We are subject to U.S. federal income tax, Oklahoma, New Mexico, Kansas, Utah, Arizona, Colorado and Iowa 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 tax years ended December 31, 2006, 2007, 2008 and 2009. We anticipate that these audits will be 
completed in 2013.

In January 2012, our Board of Directors approved a $350 million stock repurchase program, and in June 2012, approved an 
additional $350 million repurchase program that authorizes us to repurchase common stock in the open market or through privately 
negotiated transactions. The timing and amount of stock repurchases will depend on market conditions, corporate, regulatory and 
other relevant considerations. These programs may be discontinued at any time by the Board of Directors. As of December 31, 
2012, we have repurchased 6,775,729 shares at a cost of $205.6 million under these stock repurchase programs.

In May 2012, we entered into a structured share repurchase arrangement with a financial institution under which we provided an 
up-front cash payment of $100.0 million and, depending on market conditions, would either receive shares of our common stock 
or cash at the expiration of the agreement. The agreement expired in September 2012 at which time we received our up-front 
payment plus an additional $8.6 million in cash that was recorded as additional capital.

During the years ended December 31, 2012, 2011 and 2010, we withheld shares of our common stock from certain employees in 
the amounts of $22.4 million, $24.9 million and $1.2 million, respectively. These withholdings were made under the terms of 
restricted stock and performance share unit agreements, and we concurrently made cash payments to fund payroll and income 
taxes due at the vesting of restricted and performance shares in the case of officers and employees who elected to have shares 
withheld from vested amounts 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 Plan

We sponsor a non-contributory defined benefit retirement plan that covers most legacy Holly non-union employees hired prior to 
January 1, 2007 and union employees hired prior to July 1, 2010, and was closed to new entrants effective January 1, 2007 for 
non-union employees and July 1, 2010 for union employees. Effective January 1, 2012, we ceased to accrue additional benefits 
under this plan for non-union employee participants, and effective May 1, 2012, we ceased to accrue additional benefits for union 
employee participants, at which time the plan was fully frozen. The changes for union employee participants have been accounted 
for as a curtailment. Accordingly, we adjusted the projected benefit obligation and accumulated other comprehensive income by 
$7.1 million and recorded additional pension expense of $0.7 million in the second quarter of 2012. The changes related to the 
non-union employees were also accounted for as a curtailment, which was recorded in the fourth quarter of 2011. 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.

In 2012, our Compensation Committee, pursuant to authority delegated to it by the Board of Directors, approved the termination 
of the HollyFrontier Corporation Pension Plan (the “Plan”). Accordingly, our remaining liability under the Plan is expected to be 
funded in 2013. Our actual obligations under the Plan are contingent upon the timing of the pension plan termination as well as 
participant settlement obligations. We expect to record an additional expense on termination of the Plan at the date we are released 
from the liability, including the amount of actuarial loss currently recorded as accumulated other comprehensive income ($37.6 
million, $23.0 million after-tax) at December 31, 2012 plus an amount equal to any contribution we make to the Plan in excess of 
the $17.7 million accrued pension liability we have recorded at December 31, 2012.

The following table sets forth the changes in the benefit obligation and plan assets of our retirement plan for the years ended 
December 31, 2012 and 2011:

The investment policy developed for 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 Plan’s primary investment goal, rate of return objective, investment risk, investment time horizon, role of asset classes and 
asset allocation. Due to the expected termination of the Plan, the current target asset allocation is 100% cash and cash equivalents. 
The overall expected long-term rate of return on Plan assets at December 31, 2012 is 0.25% and is based on estimated returns for 
cash and cash equivalents, a Level 1 input. See Note 5, Financial Instruments, for information on Level inputs.

In 2012, we established a program for plan participants whose benefits pursuant to the defined benefit plan were frozen. The 
program provides for payments after year-end for each of the next three years provided the employee remains with us. The payments 
are based on each employee's years of service and eligible salary. For the year ended December 31, 2012, we recognized transition 
benefit costs of $15.6 million associated with transition to the new defined contribution plan.

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, we ceased to accrue benefits under this plan. We expensed $0.3 million, 
$0.6 million and $0.6 million for the years ended December 31, 2012, 2011 and 2010, respectively, in connection with this plan. 
The accrued liability reflected in the consolidated balance sheets was $7.4 million and $6.7 million at December 31, 2012 and 
2011, respectively. As of December 31, 2012, the projected benefit obligation under this plan was $7.4 million. Benefit payments, 
which reflect expected future service, are expected to be paid as follows: $0.7 million in 2013; $2.2 million in 2014; $0.5 million 
in 2015; $0.5 million in 2016; $1.5 million in 2017; and $1.4 million in 2018 through 2022.

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 $16.0 million, $9.7 million and $5.5 million for the years 
ended December 31, 2012, 2011 and 2010, respectively, in connection with these plans.

Post-retirement Healthcare Plans
We provide post-retirement medical benefits to certain eligible employees. These plans are unfunded and provide differing levels 
of  healthcare  benefits  dependent  upon  hire  date  and  work  location.  Not  all  of  our  employees  are  covered  by  these  plans  at 
December 31, 2012.

Effective December 31, 2012, we amended the post-retirement healthcare plans for participants retiring after December 31, 2012 
by eliminating post-retirement benefits after reaching age 65 and eliminating early retirement benefits for most participants who 
retire before reaching age 62. In addition, certain future retirees will receive a cash payment in lieu of post-retirement benefits 
after reaching age 65 and other changes were made generally to conform benefits. We expect to pay $8.3 million during 2013 to 
participants meeting certain requirements to receive a retiree medical transition payment.

The following table sets forth the changes in the benefit obligation and plan assets of our post-retirement healthcare plans for the 
years ended December 31, 2012 and 2011:

million and $7.1 million attributable to the HEP operations.

NOTE 20:  Contingencies and Contractual Commitments

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

Contractual Commitments
We have various long-term agreements (entered in the normal course of business) to purchase crude oil, natural gas, feedstocks 
and  other  resources  to  ensure  we  have  adequate  supplies  to  operate  our  refineries. The  substantial  majority  of  our  purchase 
obligations are based on market prices or rates. These contracts expire in 2014 through 2024.

We also have long-term agreements with third parties for the transportation and storage of crude oil, natural gas and feedstocks 
to our refineries and for terminal and storage services that expire in 2013 through 2024. At December 31, 2012, the minimum 
future transportation and storage fees under transportation agreements having terms in excess of one year are as follows:

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

The HEP segment includes all of the operations of HEP, a consolidated VIE, which owns and operates logistics assets consisting 
of petroleum product and crude oil pipelines and terminal, tankage and loading rack facilities in the Mid-Continent, Southwest 
and  Rocky  Mountain  regions  of  the  United  States. The  HEP  segment  also  includes  a  75%  interest  in  UNEV  (a  consolidated 
subsidiary of HEP) and a 25% interest in the SLC Pipeline. Revenues from the HEP segment are earned through transactions with 
unaffiliated  parties  for  pipeline  transportation,  rental  and  terminalling  operations  as  well  as  revenues  relating  to  pipeline 
transportation services provided for our refining operations. 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).

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 44% ownership interest at December 31, 2012, and its subsidiaries (collectively, “Non-Guarantor Non-
Restricted Subsidiaries”), and certain of our other subsidiaries (“Non-Guarantor Restricted Subsidiaries”) have not guaranteed 
these obligations.

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

HEP acquired our 75% interest in UNEV in July 2012. As a result, we have recast our HEP segment information to include the 
UNEV Pipeline operations as a consolidated subsidiary of HEP for all periods presented. The UNEV Pipeline was previously 
presented as a Non-Guarantor Restricted Subsidiary.

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

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

Item 9A.  Controls and Procedures

Evaluation of disclosure controls and procedures.  Our principal executive officer and principal financial officer have evaluated, 
as required by Rule 13a-15(b) under the Securities Exchange Act of 1934 (the “Exchange Act”), our disclosure controls and 
procedures (as defined in Rules 13a-15(e) and 15d-15(e)) under the Exchange Act as of the end of the period covered by this 
annual  report  on  Form  10-K.  Our  disclosure  controls  and  procedures  are  designed  to  provide  reasonable  assurance  that  the 
information  we  are  required  to  disclose  in  the  reports  that  we  file  or  submit  under  the  Exchange Act  is  accumulated  and 
communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to 
allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods 
specified in the Securities and Exchange Commission's rules and forms. Based upon the evaluation, our principal executive officer 
and principal financial officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance 
level as of December 31, 2012.

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.

of the Independent Registered Public Accounting Firm.”
