Items 1 and 2. Business and Properties

OVERVIEW

Holly Energy Partners, L.P. (“HEP”) is a Delaware limited partnership engaged principally in the business of operating a system of petroleum product and crude pipelines, storage tanks, distribution terminals, loading rack facilities and refinery processing units in Texas, New Mexico, Utah, Nevada, Oklahoma, Wyoming, Kansas, Idaho and Washington. We were formed in Delaware in 2004 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.hollyenergy.com. The information contained on our website does not constitute part of this Annual Report on Form 10-K. A copy of this Annual Report on Form 10-K will be provided without charge upon written request to the Director, Investor Relations at the above address. A direct link to our filings at the U.S. Securities and Exchange Commission (“SEC”) website is available on our website on the Investors page. Also available on our website are copies of our Governance Guidelines, Audit Committee Charter, Compensation Committee Charter, and Code of Business Conduct and Ethics, all of which will be provided without charge upon written request to the Director, Investor Relations at the above address. In this document, the words “we,” “our,” “ours” and “us” refer to HEP and its consolidated subsidiaries or to HEP or an individual subsidiary and not to any other person. “HFC” refers to HollyFrontier Corporation and its subsidiaries, other than HEP and its subsidiaries and other than Holly Logistic Services, L.L.C. (“HLS”), a subsidiary of HollyFrontier Corporation that is the general partner of the general partner of HEP and manages HEP.

Through our subsidiaries and joint ventures we own and/or operate petroleum product and crude pipelines, terminal, tankage and loading rack facilities, and refinery processing units that support the refining and marketing operations of HFC and other refineries in the Mid-Continent, Southwest and Northwest regions of the United States and Delek US Holdings, Inc.’s (“Delek”) refinery in Big Spring, Texas. At December 31, 2019, HFC owned approximately 57% of our outstanding common units as well as a non-economic general partner interest. Our assets are categorized into a Pipelines and Terminals segment and a Refinery Processing Unit segment. Segment disclosures are discussed in Note 16 to our consolidated financial statements in Part II, Item 8.

We generate revenues by charging tariffs for transporting petroleum products and crude oil through our pipelines, by charging fees for terminalling and storing refined products and other hydrocarbons, providing other services at our storage tanks and terminals and charging a tolling fee per barrel or thousand standard cubic feet of feedstock throughput in our refinery processing units. We do not take ownership of products that we transport, terminal, store or process, and therefore, we are not directly exposed to changes in commodity prices.

We have a long-term strategic relationship with HFC. Our growth plan is to continue to pursue purchases of logistic and other assets at HFC's existing refining locations in New Mexico, Utah, Oklahoma, Kansas and Wyoming. We also expect to work with HFC on logistic asset acquisitions in conjunction with HFC’s refinery acquisition strategies. Furthermore, we will continue to pursue third-party logistic asset acquisitions that are accretive to our unitholders and increase the diversity of our revenues.

On October 31, 2017, we closed on a restructuring transaction with HEP Logistics Holdings, L.P. (“HEP Logistics”), a wholly-owned subsidiary of HFC and the general partner of HEP, pursuant to which the incentive distribution rights ("IDRs") held by HEP Logistics were canceled, and HEP Logistics' 2% general partner interest in HEP was converted into a non-economic general partner interest in HEP (the "IDR Restructuring Transaction"). In consideration, we issued 37,250,000 of our common units to HEP Logistics. In addition, HEP Logistics agreed to waive $2.5 million of limited partner cash distributions for each of twelve consecutive quarters beginning with the first quarter the units issued as consideration were eligible to receive distributions. This waiver of limited partner cash distributions will expire after the cash distribution for the second quarter of 2020, which will be made during the third quarter of 2020.

PIPELINES AND TERMINALS

Pipelines

Our refined product pipelines transport light refined products from HFC’s Navajo refinery in New Mexico and Delek’s Big Spring refinery in Texas to their customers in the metropolitan and rural areas of Texas, New Mexico, Arizona, and Oklahoma and from various refineries in Utah, Wyoming, and Montana (including HFC's Woods Cross refinery in Utah) to Las Vegas, Nevada and Cedar City, Utah. The refined products transported in these pipelines include conventional gasolines, federal, state and local specification reformulated gasoline, low-octane gasoline for oxygenate blending, distillates that include high- and low-sulfur diesel and jet fuel and liquefied petroleum gases ("LPGs") (such as propane, butane and isobutane).

- 6 -

Our intermediate product pipelines consist principally of three parallel pipelines that connect the Navajo refinery, Lovington and Artesia facilities. These pipelines primarily transport intermediate feedstocks and crude oil for HFC’s refining operations in New Mexico. We also own pipelines that transport intermediate product and gas between HFC's Tulsa East and West refinery facilities.

Our crude pipelines consist of crude oil trunk, gathering and connection pipelines located in West Texas, New Mexico, Kansas, Oklahoma, Utah and Wyoming that deliver crude oil to HFC's Navajo, El Dorado and Woods Cross refineries as well as other unaffiliated refineries.

Our pipelines are regularly inspected. Generally, other than as may be provided in certain pipelines and terminal agreements, substantially all of our pipelines are unrestricted as to the direction in which product flows and the types of crude and refined products that we can transport on them. The Federal Energy Regulatory Commission ("FERC") regulates the transportation tariffs for interstate shipments on our refined product and crude oil pipelines and state regulatory agencies regulate the transportation tariffs for intrastate shipments on our pipelines.

HFC shipped an aggregate of 63% of the petroleum products transported on our refined product pipelines, 99% of the throughput volumes transported on our intermediate pipelines, and 74% of the throughput on our crude pipelines in 2019.

The following table details the average aggregate daily number of barrels of petroleum products transported on our pipelines in each of the periods set forth below for HFC and for third parties.

	Years Ended December 31,
	2019	2018	2017	2016	2015
Volumes transported for barrels per day ("bpd"):
HFC	633,270	622,088	556,516	542,762	558,027
Third parties	204,052	187,717	99,847	75,909	73,555
Total	837,322	809,805	656,363	618,671	631,582
Total barrels in thousands (“mbbls”)	305,623	295,579	239,572	226,434	230,527

Terminals, Loading Racks and Refinery Tankage

Our refined product terminals receive products from pipelines connected to HFC’s refineries and Delek’s Big Spring refinery. We then distribute them to HFC and third parties, who in turn deliver them to end-users and retail outlets. Our terminals are generally

- 10 -

complementary to our pipeline assets and serve HFC’s and Delek’s marketing activities and other customers. Terminals play a key role in moving product to the end-user market by providing the following services:

• distribution;

• blending to achieve specified grades of gasoline and diesel, including the blending of butane, ethanol and biodiesel;

• other ancillary services that include the injection of additives and filtering of jet fuel; and

• storage and inventory management.

Typically, our refined product terminal facilities consist of multiple storage tanks and are equipped with automated truck loading equipment that operates 24 hours a day. This automated system provides for control of security, allocations, and credit and carrier certification by remote input of data by our customers. In addition, nearly all of our terminals are equipped with truck loading racks capable of providing automated blending to individual customer specifications.

Our refined product terminals derive most of their revenues from terminalling fees paid by customers. We charge a fee for transferring refined products from the terminal to trucks or to pipelines connected to the terminal. In addition to terminalling fees, we generate revenues by charging our customers fees for storage, blending, injecting additives, and filtering jet fuel. HFC currently accounts for the substantial majority of our refined product terminal revenues.

Our crude terminal receives crude from Osage Pipe Line Company, LLC's ("Osage") pipeline and derives most of its revenues from throughput charges.

The table below sets forth the total average throughput for our refined product and crude terminals in each of the periods presented:

	Years Ended December 31,
	2019	2018	2017	2016	2015
Refined products and crude terminalled for (bpd):
HFC	422,119	413,525	428,001	413,487	391,292
Third parties	61,054	61,367	68,687	72,342	78,403
Total	483,173	474,892	496,688	485,829	469,695
Total (mbbls)	176,358	173,336	181,291	177,813	171,439

Our refinery tankage consists of on-site tankage at HFC’s refineries. Our refinery tankage derives its revenues from fixed fees or throughput charges in providing HFC’s refining facilities with approximately 10,454,000 barrels of storage.

Our terminals, loading racks and refinery tankage are managed by geographic region; significant assets are grouped accordingly and described below.

Mid-Continent Region

Cheyenne, Wyoming facility truck racks

The Cheyenne loading rack facilities consist of light refined product, heavy product and LPG truck racks.

CONTROL OPERATIONS OF PIPELINES AND TERMINALS

All of our pipelines are operated via satellite, microwave and radio systems from our central control room located in Artesia, New Mexico. We also monitor activity at our terminals from this control room. The control center operates with state-of-the-art Supervisory Control and Data Acquisition, or SCADA, systems. Our control center is equipped with computer systems designed to continuously monitor operational data, including refined product and crude oil throughput, flow rates, and pressures. In addition, the control center monitors alarms and throughput balances. The control center operates remote pumps, motors, engines, and valves associated with the delivery of refined products and crude oil. The computer systems are designed to enhance leak-detection capabilities, sound automatic alarms if operational conditions outside of pre-established parameters occur, and provide for remote-controlled shutdown of pump stations on the pipelines.

REFINERY PROCESSING UNITS

Our refinery processing units are integrated in HFC's El Dorado, Kansas refinery and HFC's Woods Cross, Utah refinery and are used to support their daily operations, which chemically transform crude oil into various petroleum products, including gasoline, diesel, LPGs, and asphalt.

HFC is committed to supply these units with a minimum feedstock throughput for each calendar quarter. HEP has committed that these units yield a certain level of petroleum product. The initial terms for the refinery processing units at HFC's El Dorado and Woods Cross refineries extend through 2030 and 2031, respectively.

The El Dorado units were first operational in the third and fourth quarters of 2015 and the Woods Cross units were first operational in the second quarter of 2016. These units operate on a daily basis until they are taken down for large-scale maintenance, which can be every two to four years and could last from two to four weeks. During this maintenance period (turnaround), the minimum feedstock throughput is adjusted so that HFC is not penalized for HEP's maintenance requirements.

HEP's revenue is primarily generated from the minimum throughput commitments, and HEP charges a tolling fee per barrel or thousand standard cubic feet of throughput. The tolling fee is meant to provide HEP with revenue that surpasses the amount of its expected operating costs, which include natural gas and maintenance. On any calendar month where the cost of natural gas exceeds what is included in the tolling fee, HEP will charge HFC for recovery of this additional cost. Additionally, if turnaround costs are more than expected after the first turnaround for each unit, the tolling fee will be permanently adjusted, one time, to recover these costs.

Our refinery processing units are managed by refinery personnel seconded from HFC; significant assets are grouped accordingly and described below.

El Dorado Refinery

Naphtha Fractionation Unit - El Dorado, Kansas refinery facility

The feedstock used by the naphtha fractionation unit is desulfurized naphtha, which is produced by the refinery earlier in the refining process. Desulfurized naphtha is a key component in gasoline, and this unit is used to reduce the level of benzene precursors. This allows the resulting product to be processed further to produce gasoline that meets regulatory requirements. The unit's feedstock capacity is 50,000 bpd of desulfurized naphtha.

Hydrogen Generation Unit - El Dorado, Kansas refinery facility

The hydrogen unit primarily uses natural gas as a feedstock to produce hydrogen gas that is used in HFC's operation of its El Dorado, Kansas refinery. This feedstock is supplied from purchased natural gas. The hydrogen unit's natural gas feedstock capacity is 6,100 thousand standard cubic feet per day.

Woods Cross Refinery

Crude Unit - Woods Cross, Utah refinery facility

The crude unit is comprised of several components, primarily an atmospheric distillation tower, a desalter and heat exchangers, together referred to as the crude unit. The crude unit uses black wax and other crudes as feedstock and is the first step in the refining process to separate crude into refined products. This process is accomplished by heating the crude until it is distilled into various intermediate streams. These intermediate streams are further refined downstream of the crude unit. The initial rejection of major contaminants is also performed by the crude unit. Its feedstock capacity is 15,000 bpd of crude oil.

- 15 -

Fluid Catalytic Cracking Unit - Woods Cross, Utah refinery facility

The fluid catalytic cracking unit ("FCC") is used to convert the high-boiling, high-molecular weight hydrocarbon fractions of crude oil to more valuable products like gasoline, diesel and LPGs. This conversion is performed by the cracking of petroleum hydrocarbons achieved from extremely high temperatures and fluidized catalyst. The FCC's capacity is 8,000 bpd of atmospheric tower bottoms from the crude unit, discussed above, and gas oil.

Polymerization Unit - Woods Cross, Utah refinery facility

The polymerization unit uses the LPGs, propylene and butylene, from the FCC unit and polymerizes them into high octane gasoline blendstock using heat and catalysts. This gasoline blendstock is combined with other blendstocks in the refinery to make finished gasoline. The polymerization unit's feedstock capacity is 2,500 bpd.

ACQUISITIONS

SLC Pipeline and Frontier Aspen

On October 31, 2017, we acquired the remaining 75% interest in SLC Pipeline LLC ("SLC Pipeline") and the remaining 50% interest in Frontier Aspen LLC ("Frontier Aspen") from subsidiaries of Plains, for total consideration of $250 million. Prior to this acquisition, we held noncontrolling interests of 25% of SLC Pipeline and 50% of Frontier Aspen. As a result of the acquisitions, SLC Pipeline and Frontier Aspen are wholly-owned subsidiaries of HEP.

This acquisition was accounted for as a business combination achieved in stages with the consideration allocated to the acquisition date fair value of assets and liabilities acquired. The preexisting equity interests in SLC Pipeline and Frontier Aspen were remeasured at acquisition date fair value since we have a controlling interest. We recognized a gain on the remeasurement in the fourth quarter of 2017 of $36.3 million.

SLC Pipeline is the owner of a 95-mile crude pipeline that transports crude oil into the Salt Lake City area from the Utah terminal of the Frontier Pipeline and from Wahsatch Station. Frontier Aspen is the owner of a 289-mile crude pipeline from Casper, Wyoming to Frontier Station, Utah that supplies Canadian and Rocky Mountain crudes to Salt Lake City area refiners through a connection to the SLC Pipeline.

The acquisitions above and their basis of presentation are described further in Notes 1 and 2 in notes to consolidated financial statements of HEP, and the descriptions in Notes 1 and 2 are incorporated herein by reference.

INVESTMENT IN JOINT VENTURE

On October 2, 2019, HEP Cushing LLC (“HEP Cushing”), a wholly-owned subsidiary of HEP, and Plains Marketing, L.P., a wholly-owned subsidiary of Plains, formed a 50/50 joint venture, Cushing Connect Pipeline & Terminal LLC (the “Cushing Connect Joint Venture”), for (i) the development and construction of a new 160,000 barrel per day common carrier crude oil pipeline (the “Cushing Connect Pipeline”) that will connect the Cushing, Oklahoma crude oil hub to the Tulsa, Oklahoma refining complex owned by a subsidiary of HFC and (ii) the ownership and operation of 1.5 million barrels of crude oil storage in Cushing, Oklahoma (the “Cushing Connect JV Terminal”). The Cushing Connect JV Terminal is expected to be placed in service during the second quarter of 2020, and the Cushing Connect Pipeline is expected to be placed in service during the first quarter of 2021. Long-term commercial agreements have been entered into to support the Cushing Connect Joint Venture assets.

The Cushing Connect Joint Venture has contracted with an affiliate of HEP to manage the construction and operation of the Cushing Connect Pipeline and with an affiliate of Plains to manage the operation of the Cushing Connect JV Terminal. The total Cushing Connect Joint Venture investment will generally be shared equally among HEP and Plains, and HEP estimates its share of the cost of the Cushing Connect JV Terminal contributed by Plains and Cushing Connect Pipeline construction costs are approximately $65 million. However, any Cushing Connect Pipeline construction costs exceeding 10% of the budget are borne solely by us.

The investment above and the basis of presentation is described further in Note 3 in notes to consolidated financial statements of HEP, and the description in Note 3 is incorporated herein by reference.

AGREEMENTS WITH HFC AND DELEK

We serve HFC's refineries under long-term pipeline, terminal, tankage and refinery processing unit throughput agreements expiring from 2021 to 2036. Under these agreements, HFC agrees to transport, store, and process throughput volumes of refined products, crude oil and feedstocks on our pipelines, terminal, tankage, loading rack facilities and refinery processing units that result in minimum annual payments to us. These minimum annual payments or revenues are subject to annual rate adjustments on July 1st each year based on the PPI or the FERC index. As of December 31, 2019, these agreements with HFC require minimum annualized payments to us of $348 million.

If HFC fails to meet its minimum volume commitments under the agreements in any quarter, it will be required to pay us the amount of any shortfall in cash by the last day of the month following the end of the quarter. Under certain of the agreements, a shortfall payment may be applied as a credit in the following four quarters after minimum obligations are met.

A significant reduction in revenues under these agreements could have a material adverse effect on our results of operations.

We have a pipelines and terminals agreement with Delek expiring in 2020 under which Delek has agreed to transport on our pipelines and throughput through our terminals volumes of refined products that result in a minimum level of annual revenue that also is subject to annual tariff rate adjustments. On September 30, 2019, Delek exercised its first renewal option (the “Renewal”) under the pipelines and terminals agreement for an additional five-year period beginning April 1, 2020, but only with respect to specific assets. For the refined product pipelines and refined product terminals that were not subject to the Renewal and which currently account for approximately $15 million to $16 million of HEP’s annual revenues from Delek, the agreement terminates as of March 31, 2020. In light of this development, we are exploring other potential options with respect to the pipeline and terminal assets that were not subject to the Renewal.

We also have a capacity lease agreement under which we lease space to Delek on our Orla to El Paso pipeline for the shipment of refined product. The terms for a portion of the capacity under this lease agreement expired in 2018 and were not renewed, and the remaining portions of the capacity expire in 2020 and 2022.

As of December 31, 2019, these agreements with Delek require minimum annualized payments to us of $32 million before considering the refined product pipelines and refined product terminals that were not subject to the Renewal.

Furthermore, if new laws or regulations that affect terminals or pipelines are enacted that require us to make substantial and unanticipated capital expenditures at the pipelines or terminals, we will have the right after we have made efforts to mitigate their effects to negotiate a monthly surcharge on HFC for the use of the terminals or to file for an increased tariff rate for use of the pipelines to cover HFC’s pro rata portion of the cost of complying with these laws or regulations including a reasonable rate of return. In such instances, we will negotiate in good faith with HFC to agree on the level of the monthly surcharge or increased tariff rate.

Omnibus Agreement

Under certain provisions of an omnibus agreement we have with HFC (the “Omnibus Agreement”), we pay HFC an annual administrative fee ($2.6 million in 2019) for the provision by HFC or its affiliates of various general and administrative services to us. This fee includes expenses incurred by HFC to perform centralized corporate functions, such as executive management, legal, accounting, treasury, information technology and other corporate services, including the administration of employee benefit plans. This fee does not include the salaries of personnel employed by HFC who perform services for us on behalf of HLS or the cost of their employee benefits, which are separately charged to us by HFC. We also reimburse HFC and its affiliates for direct expenses they incur on our behalf. In addition, we also pay for our own direct general and administrative costs, including costs relating to operating as a separate publicly held entity, such as costs for preparation of partners’ K-1 tax information, SEC filings, directors’ compensation, and registrar and transfer agent fees.

Under HLS’s secondment agreement with HFC (the “Secondment Agreement”), certain employees of HFC are seconded to HLS, our ultimate general partner, to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs of these employees for our benefit.

CAPITAL REQUIREMENTS

Our pipeline and terminalling operations are capital intensive, requiring investments to maintain, expand, upgrade or enhance existing operations and to meet environmental and operational regulations. Our capital requirements have consisted of, and are expected to continue to consist of, maintenance capital expenditures and expansion capital expenditures. “Maintenance capital

- 17 -

expenditures” represent capital expenditures to replace partially or fully depreciated assets to maintain the operating capacity of existing assets. Maintenance capital expenditures include expenditures required to maintain equipment reliability, tankage and pipeline integrity, safety and to address environmental regulations. “Expansion capital expenditures” represent capital expenditures to expand the operating capacity of existing or new assets, whether through construction or acquisition. Expansion capital expenditures include expenditures to acquire assets, to grow our business and to expand existing facilities, such as projects that increase throughput capacity on our pipelines and in our terminals. Repair and maintenance expenses associated with existing assets that are minor in nature and do not extend the useful life of existing assets are charged to operating expenses as incurred.

Each year the board of directors of HLS, our ultimate general partner, approves our annual capital budget, which specifies capital projects that our management is authorized to undertake. Additionally, at times when conditions warrant or as new opportunities arise, additional projects may be approved. The funds allocated for a particular capital project may be expended over a period in excess of a year, depending on the time required to complete the project. Therefore, our planned capital expenditures for a given year consist of expenditures approved for capital projects included in the current year's capital budget as well as, in certain cases, expenditures approved for capital projects in capital budgets for prior years. The 2020 capital budget is comprised of approximately $8 million to $12 million for maintenance capital expenditures, $5 million to $7 million for refinery unit turnarounds and $45 to $50 million for expansion capital expenditures and our share of Cushing Connect Joint Venture investments. We expect the majority of the 2020 expansion capital budget to be invested in our share of Cushing Connect Joint Venture investments. In addition to our capital budget, we may spend funds periodically to perform capital upgrades or additions to our assets where a customer reimburses us for such costs. The upgrades or additions would generally benefit the customer over the remaining life of the related service agreements.

We expect that our currently planned sustaining and maintenance capital expenditures, as well as expenditures for acquisitions and capital development projects, will be funded with cash generated by operations, the sale of additional limited partner common units, the issuance of debt securities and advances under our senior secured revolving credit facility (the “Credit Agreement”), or a combination thereof. With volatility and uncertainty at times in the credit and equity markets, there may be limits on our ability to issue new debt or equity financing. Additionally, due to pricing movements in the debt and equity markets, we may not be able to issue new debt and equity securities at acceptable pricing. Without additional capital beyond amounts available under the Credit Agreement, our ability to obtain funds for some of these capital projects may be limited.

Under the terms of the transaction to acquire HFC's 75% interest in UNEV, we issued to HFC a Class B unit comprising a noncontrolling equity interest in a wholly-owned subsidiary subject to redemption to the extent that HFC is entitled to a 50% interest in our share of annual UNEV earnings before interest, income taxes, depreciation and amortization above $30 million beginning July 1, 2016, and ending in June 2032, subject to certain limitations. However, to the extent earnings thresholds are not achieved, no redemption payments are required. No redemption payments have been required to date.

SAFETY AND MAINTENANCE

Many of our pipelines are subject to regulation by the Pipeline and Hazardous Materials Safety Administration (“PHMSA”) of the Department of Transportation. PHMSA has promulgated regulations governing, among other things, maximum operating pressures, pipeline patrols and leak surveys, and emergency procedures, as well as other matters intended to prevent accidents and failures. Additionally, PHMSA has promulgated regulations requiring pipeline operators to develop and implement integrity management programs for certain pipelines that, in the event of a pipeline leak or rupture, could affect “high consequence areas,” which are areas where a release could have the most significant adverse consequences, including high-population areas, certain drinking water sources and unusually sensitive ecological areas.

In addition, many states have adopted regulations, similar to, or which go above and beyond, existing PHMSA regulations, for certain intrastate pipelines. For example, Texas has developed regulatory programs that largely parallel the federal regulatory scheme and impose additional requirements for certain pipelines.

We perform preventive and normal maintenance on all of our pipeline and terminal systems and make repairs and replacements when necessary or appropriate. We also conduct routine and required inspections of our pipelines and other assets as required by regulations. We inject corrosion inhibitors as necessary into our mainlines to help control internal corrosion. External coatings and impressed current cathodic protection systems are used to protect against external corrosion. We regularly monitor, test and record the effectiveness of these corrosion-inhibiting systems. We monitor the structural integrity of covered segments of our pipeline systems through a program of periodic internal inspections using electronic “smart pigs”, hydrostatic testing, and other measures. We follow these inspections with a review of the data, and we make repairs as necessary to maintain the integrity of the pipeline. We have initiated a risk-based approach to prioritizing the pipeline segments for future smart pig runs or other appropriate integrity testing methods. This approach is intended to allow the pipelines that have the greatest risk potential to receive the highest priority in being scheduled for inspections or pressure tests for integrity. Nonetheless, the adoption of new or amended regulations or the

- 18 -

reinterpretation of existing laws and regulations by PHMSA or the states that result in more stringent or costly pipeline integrity management or safety standards could possibly have a substantial effect on us and similarly situated midstream operators.

Maintenance facilities containing equipment for pipe repairs, spare parts, and trained response personnel are located along the pipelines. Employees participate in simulated spill response exercises on a regular basis. Also they participate in actual spill response boom deployment exercises in planned spill scenarios in accordance with Oil Pollution Act of 1990 requirements.

At our terminals, tanks designed for gasoline storage are equipped with internal or external floating roofs that minimize emissions and prevent potentially flammable vapor accumulation between fluid levels and the roof of the tank. Our terminal facilities have facility response plans, spill prevention and control plans, and other plans and programs to respond to emergencies.

Many of our terminal loading racks are protected with water deluge systems activated by either heat sensors or an emergency switch. Several of our terminals are also protected by foam systems that are activated in case of fire. All of our terminals are subject to participation in a comprehensive environmental management program to assure compliance with applicable air, solid waste, and wastewater regulations.

For further information on pipeline safety and regulatory requirements related to maintenance, see our risk factor "Federal and state legislative and regulatory initiatives relating to pipeline safety that require the use of new or more stringent safety controls or result in more stringent enforcement of applicable legal requirements could subject us to increased capital costs, operational delays or costs of operation."

COMPETITION

As a result of our physical integration with HFC’s refineries, our contractual relationship with HFC under the Omnibus Agreement and the HFC pipelines and terminals, tankage and throughput agreements, we believe that we will not face significant competition for barrels of crude oil transported to or refined products transported from HFC’s refineries, particularly during the terms of our long-term transportation agreements with HFC expiring between 2021 and 2036.

However, we do face competition from other pipelines that may be able to supply the end-user markets of HFC or other customers with refined products on a more competitive basis. Additionally, if HFC’s wholesale customers reduced their purchases of refined products due to the increased availability of cheaper product from other suppliers or for other reasons, the volumes transported through our pipelines could be reduced, which, subject to the minimum revenue commitments, could cause a decrease in cash and revenues generated from our operations.

The petroleum refining business is highly competitive. Among HFC’s competitors are some of the world’s largest integrated petroleum companies, which have their own crude oil supplies and distribution and marketing systems. HFC competes with independent refiners as well. Competition in particular geographic areas is affected primarily by the amounts of refined products produced by refineries located in such areas and by the availability of refined products and the cost of transportation to such areas from refineries located outside those areas.

In addition, we face competition from trucks that deliver product in a number of areas we serve. Although their costs may not be competitive for longer hauls or large volume shipments, trucks compete effectively for incremental and marginal volumes in many areas we serve. The availability of truck transportation places some competitive constraints on us.

Our refined product terminals compete with other independent terminal operators as well as integrated oil companies based on terminal location, price, versatility and services provided. Our competition primarily comes from integrated petroleum companies, refining and marketing companies, independent terminal companies and distribution companies with marketing and trading arms. Historically, the significant majority of the throughput at our terminal facilities has come from HFC.

RATE REGULATION

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

- 19 -

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

While FERC regulates the rates for interstate shipments on our refined product pipelines, the New Mexico Public Regulation Commission regulates the rates for intrastate shipments in New Mexico, the Texas Railroad Commission regulates the rates for intrastate shipments in Texas and the Oklahoma Corporation Commission regulates the rates for intrastate shipments in Oklahoma. State commissions have generally not been aggressive in regulating common carrier pipelines and generally have not investigated the rates or practices of petroleum pipelines in the absence of shipper complaints, and we do not believe the intrastate tariffs now in effect are likely to be challenged. However, a state regulatory commission could investigate our rates if such a challenge were filed.

ENVIRONMENTAL REGULATION AND REMEDIATION

Our operation of pipelines, terminals, and associated facilities in connection with the transportation and storage of refined products and crude oil is subject to stringent and complex federal, state, and local laws and regulations governing the potential discharge of materials into the environment, or otherwise relating to the protection of the environment and natural resources. These laws and regulations may require us to obtain permits for our operations or result in the imposition of strict requirements relating to air emissions, biodiversity, wastewater discharges, waste management, spill planning and prevention and the remediation of contamination. As with the industry generally, compliance with existing, changing, and new laws, regulations, interpretations and guidance increases our overall cost of business, including our capital costs to construct, maintain, upgrade and operate equipment and facilities. These laws and regulations affect our operations, maintenance, capital expenditures and net income, as well as those of our competitors. These laws and regulations, and the interpretation or enforcement thereof, are subject to frequent change by regulatory authorities, and we are unable to predict the ongoing cost to us of complying with these laws and regulations or the future impact of these laws and regulations on our operations. Violation of environmental laws, regulations, and permits can result in the imposition of significant administrative, civil and criminal penalties, and injunctions, construction bans or delays; delays in the permitting, development or expansion of projects; limitations or prohibitions on certain operations; and reputational harm. In addition, many environmental laws contain citizen suit provisions, allowing environmental groups to bring suits to enforce compliance with environmental laws. Environmental groups frequently challenge pipeline infrastructure projects. Moreover, a major discharge of hydrocarbons or hazardous substances into the environment could, to the extent the event is not insured, subject us to substantial expense, including both the cost to comply with applicable laws and regulations and claims made by employees, neighboring landowners and other third parties for personal injury and property damage.

Contamination resulting from spills of refined products and crude oil is not unusual within the petroleum pipeline industry. Historic spills along our existing pipelines and terminals as a result of past operations have resulted in contamination of the environment, including soils and groundwater. Some environmental laws impose liability without regard to fault or the legality of the original act on certain classes of persons that contributed to the releases of hazardous substances or petroleum hydrocarbon substances into the environment. These persons include the owner or operator of the site or sites where the release occurred and companies that disposed of, or arranged for the disposal of, the hazardous substances found at the site. Such persons may be subject to strict, joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources, and for the costs of certain health studies. Site conditions, including soils and groundwater, are being evaluated at a few of our properties where operations may have resulted in releases of hydrocarbons and other wastes, none of which we believe will have a significant effect on our operations since the remediation of such releases would be covered under environmental indemnification agreements.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers.

We have an environmental agreement with Delek with respect to pre-closing environmental costs and liabilities relating to the pipelines and terminals acquired from Delek in 2005, under which Delek will indemnify us subject to certain monetary and time limitations.

- 20 -

There are environmental remediation projects that are currently in progress that relate to certain assets acquired from HFC. Certain of these projects were underway prior to our purchase and represent liabilities of HFC as the obligation for future remediation activities was retained by HFC. At December 31, 2019, we have an accrual of $5.5 million that relates to environmental clean-up projects for which we have assumed liability or for which the indemnity provided for by HFC has expired. The remaining projects, including assessment and monitoring activities, are covered under the HFC environmental indemnification discussed above and represent liabilities of HFC.

We may experience future releases into the environment from our pipelines and terminals or discover historical releases that were previously unidentified or not assessed. Although we maintain an extensive inspection and audit program designed, as applicable, to prevent, detect and address these releases promptly, damages and liabilities incurred due to any future environmental releases from our assets have the potential to substantially affect our business.

EMPLOYEES

Neither we nor our general partner has employees. Direct support for our operations is provided by HLS, which utilizes 299 people employed by HFC dedicated to performing services for us. We reimburse HFC for direct expenses that HFC or its affiliates incurs on our behalf for these employees.  HFC considers its employee relations to be good.

Under the Secondment Agreement with HFC, certain employees of HFC are seconded to HLS, our ultimate general partner, to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs of these employees for our benefit.

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 consider the following risk factors carefully 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, results of operations or treatment of unitholders could be materially and adversely affected.

The headings provided in this Item 1A. are for convenience and reference purposes only and shall not affect or limit the extent or interpretation of the risk factors.

RISKS RELATED TO OUR BUSINESS

If we are unable to generate sufficient cash flow, our ability to pay quarterly distributions to our common unitholders at current levels or to increase our quarterly distributions in the future could be impaired materially.

Our ability to pay quarterly distributions depends primarily on cash flow (including cash flow from operations, financial reserves and credit facilities) and not solely on profitability, which is affected by non-cash items. As a result, we may pay cash distributions during periods of losses and may be unable to pay cash distributions during periods of income. Our ability to generate sufficient cash from operations is largely dependent on our ability to manage our business successfully which may also be affected by economic, financial, competitive, regulatory, and other factors that are beyond our control. Because the cash we generate from operations will fluctuate from quarter to quarter, quarterly distributions may also fluctuate from quarter to quarter.

We depend on HFC (particularly its Navajo and Woods Cross refineries) for a substantial portion of our revenues; if those revenues were significantly reduced or if HFC's financial condition materially deteriorated, there would be a material adverse effect on our results of operations.

For the year ended December 31, 2019, HFC accounted for 66% of the revenues of our petroleum product and crude pipelines, 87% of the revenues of our terminals, tankage, and truck loading racks, and 100% of the revenue from our refinery processing units. We expect to continue to derive a majority of our revenues from HFC for the foreseeable future. If HFC satisfies only its minimum obligations under the long-term pipeline and terminal, tankage and throughput agreements that it has with us or is unable to meet its minimum annual payment commitment for any reason, including due to prolonged downtime or a shutdown at its refineries, our revenues and cash flow would decline.

Any significant reduction in production at HFC’s Navajo or Woods Cross refineries could reduce throughput in our pipelines, terminals and refinery processing units, resulting in materially lower levels of revenues and cash flow for the duration of the shutdown. For the year ended December 31, 2019, production from HFC's Navajo and Woods Cross refineries accounted for approximately 50% of the throughput volumes transported by our refined product, intermediate and crude pipelines. Our Woods Cross refinery processing units also accounted for 73% of our refinery processing units revenues.

Operations at any of HFC's refineries could be partially or completely shut down, temporarily or permanently, as the result of:

• competition from other refineries and pipelines that may be able to supply the refinery's end-user markets on a more cost-effective basis;

• operational problems such as catastrophic events at the refinery, terrorist or cyberattacks, domestic vandalism, labor difficulties, environmental proceedings or other litigation that cause a stoppage of all or a portion of the operations at the refinery;

• planned maintenance or capital projects;

• increasingly stringent environmental laws and regulations, such as the U.S. Environmental Protection Agency's gasoline and diesel sulfur control requirements that limit the concentration of sulfur in motor gasoline and diesel fuel for both on-road and non-road usage as well as various state and federal emission requirements that may affect the refinery itself and potential future climate change regulations;

• an inability to obtain crude oil for the refinery at competitive prices; or

• a general reduction in demand for refined products in the area 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;

- 22 -

◦ higher gasoline prices due to higher crude oil costs, higher taxes or stricter environmental laws or regulations; or

◦ a shift by consumers to more fuel-efficient or alternative fuel vehicles or an increase in fuel economy, whether as a result of technological advances by manufacturers, legislation either mandating or encouraging higher fuel economy or the use of alternative fuel or otherwise. 

The effect on us of any shutdown would depend on the length of the shutdown and the extent of the refinery operations affected by the shutdown. We have no control over the factors that may lead to a shutdown or the measures HFC may take in response to a shutdown. HFC makes all decisions at each of its refineries concerning levels of production, regulatory compliance, refinery turnarounds (planned shutdowns of individual process units within the refinery to perform major maintenance activities), labor relations, environmental remediation, emission control and capital expenditures and is responsible for all related costs. HFC is not under contractual obligation to us to maintain operations at its refineries.

Furthermore, HFC's obligations under the long-term pipeline and terminal, tankage, tolling and throughput agreements with us would be temporarily suspended during the occurrence of a force majeure event that renders performance impossible with respect to an asset for at least 30 days. If such an event were to continue for a year, we or HFC could terminate the agreements. The occurrence of any of these events could reduce our revenues and cash flows.

Due to our lack of asset and geographic diversification, adverse developments in our businesses could materially and adversely affect our financial condition, results of operations, or cash flows.

We have limited asset and geographic diversification, especially our large concentration of pipeline assets serving HFC's Navajo refinery, an adverse development in our business (including adverse developments due to catastrophic events or weather, terrorist or cyberattacks, domestic vandalism, decreased supply of crude oil and feedstocks and/or decreased demand for refined petroleum products), could have a significantly greater impact on our financial condition and results of operations than if we maintained more diverse assets in more diverse locations.

Increases in interest rates could adversely affect our business.

We use both fixed and variable rate debt, and we are exposed to market risk due to the floating interest rates on our credit facility. In addition, interest rates on future debt offerings could be higher, causing our financing costs to increase accordingly. Our results of operations, cash flows and financial position could be adversely affected by significant increases in interest rates above current levels.

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

As of December 31, 2019, the principal amount of our total outstanding debt was $1,466 million. On February 4, 2020, we closed a private placement of $500 million 5.0% senior notes due 2028 (the “5% Senior Notes”). On February 5, 2020, we redeemed our $500 million 6% Senior Notes due 2024. Various limitations in our Credit Agreement and the indenture for our 5.0% Senior Notes may reduce our ability to incur additional debt, to engage in some transactions and to capitalize on business opportunities. Any subsequent refinancing of our current indebtedness or any new indebtedness could have similar or greater restrictions.

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

The instruments governing our debt contain restrictive covenants that may prevent us from engaging in certain transactions. The agreements governing our debt generally require us to comply with various affirmative and negative covenants including the maintenance of certain financial ratios and restrictions on incurring additional debt, entering into mergers, consolidations and sales of assets, making investments and granting liens. Our leverage may affect adversely our ability to fund future working capital, capital expenditures and other general partnership requirements, future acquisitions, construction or development activities, or to otherwise realize fully the value of our assets and opportunities because of the need to dedicate a substantial portion of our cash

- 23 -

flow from operations to payments on our indebtedness or to comply with any restrictive terms of our indebtedness. Our leverage also may make our results of operations more susceptible to adverse economic and industry conditions by limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate and may place us at a competitive disadvantage as compared to our competitors that have less debt.

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

The renewal or replacement of existing contracts with our customers at rates sufficient to maintain current revenues and cash flows depends on a number of factors outside our control, including competition from other pipelines and the demand for refined products in the markets that we serve. Our long-term pipeline and terminal, tankage and refinery processing unit throughput agreements with HFC and Delek will expire beginning in 2020 through 2026. On September 30, 2019, Delek exercised its first renewal option (the “Renewal”) under this agreement for an additional five-year period beginning April 1, 2020, but only with respect to specific assets. For the refined product pipelines and refined product terminals that were not subject to the Renewal and which currently account for approximately $15 million to $16 million of our annual revenues from Delek, the agreement terminates as of March 31, 2020. In light of this development, we are exploring other potential options with respect to the pipeline and terminal assets that were not subject to the Renewal. No assurances can be given that we will be able to find new customers or that the tariff rates we achieve on the assets not contractually renewed by Delek will be similar to the tariff rates we had with Delek.

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, including U.S. government shutdowns, 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:

• continue our business as currently structured and/or conducted;

• meet our obligations as they come due;

• execute our growth strategy;

• complete future acquisitions or construction projects;

• take advantage of other business opportunities; or

• respond to competitive pressures.

Any of the above could have a material adverse effect on our revenues and results of operations.

We may not be able to fully execute our growth strategy if we encounter illiquid capital markets or increased competition for investment opportunities, if our assumptions concerning population growth are inaccurate, or if an agreement cannot be reached with HFC for the acquisition of assets on which we have a right of first offer.

Our strategy contemplates growth through the development and acquisition of crude, intermediate and refined products transportation and storage assets while maintaining a strong balance sheet. This strategy includes constructing and acquiring additional assets and businesses, either from HFC or third parties, to enhance our ability to compete effectively and diversifying our asset portfolio, thereby providing more stable cash flow. We regularly consider and enter into discussions regarding, and are currently contemplating and/or pursuing, potential joint ventures, stand-alone projects or other transactions that we believe will present opportunities to realize synergies, expand our role in our chosen businesses and increase our market position.

We will require substantial new capital to finance the future development and acquisition of assets and businesses. Any limitations on our access to capital will impair our ability to execute this strategy. If the cost of such capital becomes too expensive, or if the development or acquisition opportunities are on terms that do not allow us to obtain appropriate financing, our ability to develop or acquire accretive assets will be limited. We may not be able to raise the necessary funds on satisfactory terms, if at all. The

- 24 -

primary factors that influence our cost of equity include market conditions, fees we pay to underwriters and other offering costs, which include amounts we pay for legal and accounting services. The primary factors influencing our cost of borrowing include interest rates, credit spreads, credit ratings, covenants, underwriting or loan origination fees and similar charges we pay to lenders.

In addition, we experience competition for the types of assets and businesses we have historically purchased or acquired. High competition, particularly for a limited pool of assets, may result in higher, less attractive asset prices, and therefore, we may lose to more competitive bidders. Such occurrences limit our ability to execute our growth strategy, which may materially adversely affect our ability to maintain or pay higher distributions in the future.

Our growth strategy also depends upon:

• the accuracy of our assumptions about growth in the markets that we currently serve or have plans to serve in the Southwestern, Northwest and Mid-Continent regions of the United States;

• HFC's willingness and ability to capture a share of additional demand in its existing markets; and

• HFC's willingness and ability to identify and penetrate new markets in the Southwestern, Northwest and Mid-Continent regions of the United States.

If our assumptions about increased market demand prove incorrect, HFC may not have any incentive to increase refinery capacity and production or shift additional throughput to our pipelines, which would adversely affect our growth strategy.

Our Omnibus Agreement with HFC provides us with a right of first offer on certain of HFC’s existing or acquired logistics assets. The consummation and timing of any future acquisitions of these assets will depend upon, among other things, our ability to negotiate acceptable purchase agreements and commercial agreements with respect to the assets and our ability to obtain financing on acceptable terms. We can offer no assurance that we will be able to successfully consummate any future acquisitions pursuant to our right of first offer. In addition, certain of the assets covered by our right of first offer may require substantial capital expenditures in order to maintain compliance with applicable regulatory requirements or otherwise make them suitable for our commercial needs. For these or a variety of other reasons, we may decide not to exercise our right of first offer if and when any assets are offered for sale, and our decision will not be subject to unitholder approval. In addition, our right of first offer may be terminated upon a change of control of HFC.

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

We are subject to risks of loss resulting from nonpayment or nonperformance by our customers, vendors or other counterparties. We derive a significant portion of our revenues from contracts with key customers, particularly HFC, under its pipelines and terminals, tankage, tolling and throughput agreements. To the extent that our customers may be unable to meet the specifications of their customers, we would be adversely affected unless we were able to make comparably profitable arrangements with other customers.

Mergers among our existing customers could provide strong economic incentives for the combined entities to use systems other than ours, and we could experience difficulty in replacing lost volumes and revenues. Because a significant portion of our operating costs are fixed, a reduction in volumes would result not only in a reduction of revenues, but also a decline in net income and cash flow of a similar magnitude, which would reduce our ability to meet our financial obligations and make distributions to unitholders.

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.

In addition, in connection with the acquisition of certain of our assets, we have entered into agreements pursuant to which various counterparties, including HFC, have agreed to indemnify us, subject to certain limitations, for:

• certain pre-closing environmental liabilities discovered within specified time periods after the date of the applicable acquisition;

• certain matters arising from the pre-closing ownership and operation of assets; and

• ongoing remediation related to the assets.

- 25 -

Our business, results of operation, cash flows and our ability to make cash distributions to our unitholders could be adversely affected in the future if third parties fail to satisfy an indemnification obligation owed to us.

A material decrease in the supply, or a material increase in the price, of crude oil available to HFC's refineries, and a corresponding decrease in demand for refined products in the markets served by our pipelines and terminals, could reduce our revenues materially.

The volume of refined products we transport in our refined product pipelines depends on the level of production of refined products from HFC's refineries, which, in turn, depends on the availability of attractively-priced crude oil produced in the areas accessible to those refineries. In order to maintain or increase production levels at their refineries, our shippers must continually contract for new crude oil supplies. A material decrease in crude oil production from the fields that supply their refineries, as a result of depressed commodity prices, decreased demand, lack of drilling activity, natural production declines or otherwise, could result in a decline in the volume of crude oil our shippers refine, absent the availability of transported crude oil to offset such declines. Such an event would result in an overall decline in volumes of refined products transported through our pipelines and therefore a corresponding reduction in our cash flow. In addition, the future growth of our shippers' operations will depend in part upon whether our shippers can contract for additional supplies of crude oil at a greater rate than the rate of natural decline in their currently connected supplies.

Fluctuations in crude oil prices can greatly affect production rates and investments by third parties in the development of new oil reserves. Drilling activity generally decreases as crude oil prices decrease. We and our shippers have no control over producers or their production decisions, which are affected by, among other things, prevailing and projected energy prices, demand for hydrocarbons, geological considerations, governmental regulation, global market conditions, actions by foreign nations and the availability and cost of capital, or over the level of drilling activity in the areas of operations, the amount of reserves underlying the wells and the rate at which production from a well will decline. Similarly, a material increase in the price of crude oil supplied to our shippers' refineries without an increase in the market value of the products produced by the refineries, either temporary or permanent, which causes a reduction in the production of refined products at the refineries, would cause a reduction in the volumes of refined products we transport, and our cash flow could be adversely affected.

Finally, our business depends in large part on the demand for the various petroleum products we gather, transport and store in the markets we serve. Reductions in that demand adversely affect our business. Market demand varies based upon the different end uses of the petroleum products we gather, transport and store. We cannot predict the impact of future fuel conservation measures, alternate fuel requirements, government regulation, technological advances in fuel economy and energy-generation devices, exploration and production activities, and actions by foreign nations, any of which could reduce the demand for the petroleum products in the areas we serve.

Our operations are subject to evolving federal, state and local laws, regulations and permit/authorization requirements regarding environmental protection, health, operational safety and product quality. Potential liabilities arising from these laws, regulations and requirements could affect our operations and adversely affect our performance.

Our pipelines and terminal, tankage and loading rack operations are subject to increasingly stringent environmental and safety laws and regulations.

Environmental laws and regulations have raised operating costs for the oil and refined products industry, and compliance with such laws and regulations may cause us, and the HFC and other refineries that we support, to incur potentially material capital expenditures associated with the construction, maintenance, and upgrading of equipment and facilities. Future environmental, health and safety requirements (or changed interpretations of existing requirements) and regulatory changes generally may impose new and/or more stringent requirements on our assets and operations and require us to incur potentially material expenditures to ensure our continued compliance.

Our operations require numerous permits and authorizations under various laws and regulations, including environmental and worker health and safety laws and regulations. In May 2015, the EPA published a final rule that has the potential to greatly expand the definition of "waters of the United States" (“WOTUS”) under the federal Clean Water Act ("CWA") and the jurisdiction of the Corps, but in September 2019 the EPA and Corps rescinded the WOTUS rule. On January 23, 2020, the EPA and the Corps finalized the Navigable Waters Protection Rule, which narrows the definition of WOTUS relative to the prior 2015 rulemaking. However, legal challenges to the new rule are expected, and multiple challenges to the EPA’s prior rulemakings remain pending leaving the scope of jurisdiction under the CWA uncertain at this time. Any increase in scope could result in increased costs and delays with respect to obtaining permits for dredge and fill activities in wetland areas. These and other authorizations and permits are subject to revocation, renewal, modification, or third-party challenge, and can require operational changes that may involve significant costs to limit impacts or potential impacts on the environment and/or worker health and safety. A violation of these

- 26 -

authorization or permit conditions or other legal or regulatory requirements could result in substantial fines, criminal sanctions, permit revocations and injunctions prohibiting our operations. In addition, major modifications of our operations could require modifications to our existing permits or expensive upgrades to our existing pollution control equipment that could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We may also be required to address conditions discovered in the future that require environmental response actions or remediation. The transportation and storage of refined products produces a risk that refined products and other hydrocarbons may be suddenly or gradually released into the environment, potentially causing substantial expenditures for a response action, significant government penalties, liability to government agencies for natural resources damages, personal injury or property damages to private parties and significant business interruption. Further, we own or lease a number of properties that have been used to store or distribute refined products for many years. Many of these properties have also been operated by third parties whose handling, disposal, or release of hydrocarbons and other wastes were not under our control. Environmental laws can impose strict, joint and several liability for releases of hazardous substances into the environment, and we could find ourselves liable for past releases caused by third parties. If we were to incur a significant liability pursuant to environmental laws or regulations, it could have a material adverse effect on us.

There are various risks associated with greenhouse gases and climate change legislation or regulations that could result in increased operating costs and reduced demand for our services.

Climate change continues to attract considerable attention in the United States. Numerous proposals have been made and could continue to be made at the national, regional and state levels of government to monitor and limit existing emissions of greenhouse gases ("GHGs") as well as to restrict or eliminate such future emissions. As a result, our operations, and those of our customers, are subject to a series of regulatory, political, litigation, and financial risks associated with the transport of fossil fuels and emission of GHGs.

The EPA has determined that emissions of carbon dioxide, methane and other GHG emissions present an endangerment to public health and the environment because emissions of such gases are, according to the EPA, contributing to warming of the earth's atmosphere and other climatic changes. The U.S. Supreme Court has also found that GHG emissions constitute a pollutant under the CAA. Accordingly, the EPA has adopted rules that, among other things, establish construction and operating permit reviews for GHG emissions from certain large stationary sources, require the monitoring and annual reporting of GHG emissions from certain petroleum and natural gas sources in the United States or to control or reduce emissions of GHGs, including methane, from such sources. In addition, the EPA, together with the DOT, implement GHG emission and corporate average fuel economy standards for vehicles manufactured in the United States. Additionally, various states and groups of states have adopted or are considering adopting legislation, regulations or other regulatory initiatives that are focused on such areas as GHG cap and trade programs, carbon taxes, reporting and tracking programs, and restriction of emissions. Any such legislation or regulatory programs could also increase the cost of consuming, and thereby reduce demand for, the crude oil and refined products that we deliver. Additionally, political, litigation and financial risks related to climate change may result in curtailed refinery activity, increased regulation, or other adverse direct and indirect effects on our business, financial condition and results of operations.

We may incur significant costs and liabilities resulting from performance of pipeline integrity programs and related repairs.

We are regulated under federal pipeline safety statutes by DOT through the Pipeline and Hazardous Materials Safety Administration ("PHMSA"). PHMSA sets and enforces pipeline safety regulations. Failure to comply with PHMSA or comparable state pipeline safety regulations could result in a number of consequences which may have an adverse effect on our operations. PHMSA’s enforcement authority includes the ability to assess civil penalties for violations of pipeline safety regulations, issue orders directing compliance, and issue orders directing corrective action to abate hazardous conditions. Among other things, pipeline safety laws and regulations require pipeline operators to develop integrity management programs, including more frequent inspections and other measures for pipelines located in “high consequence areas,” which are areas where a release could have the most significant adverse consequences, including certain population areas, certain drinking water sources and unusually sensitive ecological areas. These regulations require operators of covered pipelines to perform a variety of heightened assessment, analysis, prevention and repair activities. Routine assessments under the integrity management program may result in findings that require repairs or other actions.

Moreover, changes to pipeline safety laws by Congress and regulations by PHMSA or states that result in more stringent or costly safety standards could possibly have a substantial effect on us and similarly situated midstream operators. For example, in October 2019, PHMSA published two final rules on pipeline safety. The Enhanced Emergency Order Procedures rule (effective December 2, 2019) implements an existing statutory authorization for PHMSA to issue emergency orders related to pipeline safety if unsafe conditions or practices, or a combination thereof, constitutes or causes an imminent hazard. The Safety of Hazardous Liquid Pipelines rule (effective July 1, 2020) expands PHMSA’s regulation of the safety of hazardous liquid pipelines by extending

- 27 -

reporting requirements to certain hazardous liquid gravity pipelines and rural gathering pipelines, establishing additional integrity management requirements for hazardous liquid pipelines that could affect high consequence areas, adding new assessment and integrity requirements for certain other hazardous liquid pipelines, and expanding various inspection and leak detection requirements. We are in the process of assessing the impact of these rules on our future costs of operations and revenue from operations.

These changes could result in additional requirements. Any such new and expanded requirements may result in additional capital costs, possible operational delays and increased costs of operation that, in some instances, may be significant.

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

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

In addition, 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 and terminal operations could disrupt our operations by impeding our processing of transactions, our ability to protect customer or company information and our financial reporting. Although we have taken steps to address these concerns by implementing sophisticated network security and internal control measures, a system failure or data security breach could have a material adverse effect on our financial condition and results of operations.

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

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

Despite our security measures, our information systems may become the target of cyberattacks or security breaches (including employee error, malfeasance or other breaches), which could result in the theft or loss of the stored information, misappropriation of assets, disruption of transactions and reporting functions, our ability to protect confidential information and our financial reporting. Even with insurance coverage, a claim could be denied or coverage delayed. A cyberattack or security breach could result in liability under data privacy laws, regulatory penalties, damage to our reputation, or additional costs for remediation and modification or enhancement of our information systems to prevent future occurrences, all of which could have a material and adverse effect on our business, financial condition or results of operations.

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

Our operations are subject to catastrophic losses, operational hazards and unforeseen interruptions such as natural disasters, adverse weather, tornadoes, earthquakes, accidents, fires, explosions, hazardous materials releases, terror or cyberattacks, domestic vandalism, mechanical failures and other events beyond our control. These events could result in an injury, loss of life, or property damage or destruction, as well as a curtailment or interruption in our operations. In addition, third-party damage, mechanical malfunctions, undetected leaks in pipelines, faulty measurement or other errors may result in significant costs or lost revenues.

- 28 -

We may not be able to maintain or obtain insurance of the type and amount we desire at commercially reasonable rates and exclusions from coverage may limit our ability to recover the amount of the full loss in all situations. As a result of market conditions, our premiums and deductibles for certain of our insurance policies could increase. In some instances, certain insurance could become unavailable or available only for reduced amounts of coverage.

There can be no assurance that insurance will cover all or any damages and losses resulting from these types of hazards. We are not fully insured against all risks or incidents to our business and therefore, we self-insure certain risks. We are not insured against all environmental accidents that might occur, other than limited coverage for certain third party sudden and accidental claims. Our property insurance includes business interruption coverage for lost profit arising from physical damage to our facilities. If a significant accident or event occurs that is self-insured or not fully insured, our operations could be temporarily or permanently impaired, our liabilities and expenses could be significant and it could have a material adverse effect on our financial position. Because our partnership agreement requires us to distribute all available cash (less operating surplus cash reserves) to our unitholders, we do not have the same flexibility as other legal entities to accumulate cash to protect against underinsured or uninsured losses.

Competition from other pipelines that may be able to supply our shippers' customers with refined products at a lower price could cause us to reduce our rates or could reduce our revenues.

We and our shippers could face increased competition if other pipelines are able to supply our shippers' end-user markets competitively with refined products. For example, increased supplies of refined product delivered by Kinder Morgan's El Paso to Phoenix pipeline could result in additional downward pressure on wholesale-refined product prices and refined product margins in El Paso and related markets. Additionally, further increases in products from Gulf Coast refiners entering the El Paso and Arizona markets on this and other pipelines and a resulting increase in the demand for shipping product on the interconnecting common carrier pipelines could cause a decline in the demand for refined product from HFC. This could reduce our opportunity to earn revenues from HFC in excess of its minimum volume commitment obligations.

An additional factor that could affect some of HFC's markets is excess pipeline capacity from the West Coast into our shippers' Arizona markets. Additional increases in shipments of refined products from the West Coast into our shippers' Arizona markets could result in additional downward pressure on refined product prices that, if sustained over the long term, could influence product shipments by HFC to these markets.

Any reduction in the capacity of, or the allocations to, our shippers on interconnecting, third-party pipelines could cause a reduction of volumes transported in our pipelines and through our terminals.

HFC and the other users of our pipelines and terminals are dependent upon connections to third-party pipelines to receive and deliver crude oil and refined products. Any reduction of capacities of these interconnecting pipelines due to testing, line repair, reduced operating pressures, catastrophic events, terror or cyberattacks, domestic vandalism or other causes could result in reduced volumes transported in our pipelines or through our terminals. Similarly, if additional shippers begin transporting volumes of refined products over interconnecting pipelines, the allocations to existing shippers in these pipelines would be reduced, which could also reduce volumes transported in our pipelines or through our terminals.

We could be subject to damages based on claims brought against us by our customers or lose customers as a result of the failure of products we distribute to meet certain quality specifications. In addition, we could be required to make substantial expenditures in the event of any changes in product quality specifications.

A significant portion of our operating responsibility on refined product pipelines is to ensure the quality and purity of the products loaded at our loading racks. If our quality control measures fail, off-specification product could be sent out to public gasoline stations. This type of incident could result in liability claims regarding damages caused by the off-specification fuel or could impact our ability to retain existing customers or to acquire new customers, any of which could have a material adverse impact on our results of operations and cash flows.

In addition, various federal, state and local agencies have the authority to prescribe specific product quality specifications of refined products. Changes in product quality specifications or blending requirements could reduce our throughput volume, require us to incur additional handling costs or require capital expenditures. For example, different product specifications for different markets impact the fungibility of the products in our system and could require the construction of additional storage. If we are unable to recover these costs through increased revenues, our cash flows and ability to pay cash distributions could be adversely affected. In addition, changes in the product quality of the products we receive on our petroleum products pipeline system could reduce or eliminate our ability to blend products.

Growing our business by constructing new pipelines and terminals, or expanding existing ones, subjects us to construction risks.

One of the ways we may grow our business is through the construction of new pipelines and terminals or the expansion of existing ones. The construction of a new pipeline or the expansion of an existing pipeline, by adding horsepower or pump stations or by adding a second pipeline along an existing pipeline, involves numerous regulatory, environmental, political, and legal uncertainties, most of which are beyond our control. For example, pipeline construction projects requiring federal approvals are generally subject to environmental review requirements under the National Environmental Policy Act, and must also comply with other natural resource review requirements imposed pursuant to the Endangered Species Act and the National Historic Preservation Act. These projects may not be completed on schedule (or at all) or at the budgeted cost. In addition, our revenues may not increase immediately upon the expenditure of funds on a particular project. For instance, if we build a new pipeline, 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 facilities may not be able to attract enough throughput to achieve our expected investment return, which could adversely affect our results of operations and financial condition.

Rate regulation, changes to rate-making rules, or a successful challenge to the rates we charge on our pipeline systems may reduce our revenues and the amount of cash we generate.

FERC regulates the tariff rates for interstate movements and state regulatory authorities regulate the tariff rates for intrastate movements on our pipeline systems. These regulatory agencies periodically implement new rules, regulations, and policies that may adversely affect our terms and conditions of service as well as the rates charged for our services or our costs of operation.

Additionally, these agencies have the responsibility of determining compliance with the laws they administer and orders they issue. For example, FERC has monetary penalty authority under the ICA, and failure to comply with the ICA or FERC’s regulations or orders could subject us to penalty liability. Should an agency determine our pipelines are subject to additional regulation or determine that we failed to comply with applicable law, it could adversely affect our results of operations, revenues, and profitability.

The primary oil pipeline rate-making methodology of FERC is price indexing. We use this methodology for all of our FERC-regulated interstate transportation services. The indexing method allows a pipeline to increase its rates based on a percentage change in the PPI for finished goods. If the index falls, we will be required to reduce our rates that are based on FERC's price indexing methodology if they exceed the new maximum allowable rate. If the FERC price indexing methodology permits a rate increase that is not large enough to fully reflect actual increases in our costs, we may need to file for a rate increase using an alternative method with a higher burden of proof and without the guarantee of success. These FERC rate-making methodologies may limit our ability to set rates based on our true costs or may delay the use of rates that reflect increased costs.

If a party with an economic interest were to file either a protest of our proposal for increased rates or a complaint against our existing tariff rates or terms and conditions of service, or FERC were to initiate an investigation of our existing rates or terms and conditions of service, then our rates and tariff provisions could be subject to detailed review. If our proposed rate increases were found to be in excess of levels justified by our cost of service, FERC could order us to reduce our rates, and to refund the amount by which the rate increases were determined to be excessive, plus interest. If our existing rates were found to be in excess of our cost of services, we could be ordered to refund the excess we collected for up to two years prior to the date of the filing of the complaint challenging the rates, and we could be ordered to reduce our rates prospectively. Due to the complexity of ratemaking, the lawfulness of any rate is never assured. A successful challenge of our rates could adversely affect our revenues.

In March and July of 2018, FERC issued a revised policy statement and order on rehearing in which it expressed a general policy that it will no longer permit an income tax allowance to be included in the cost-of-service rates for interstate pipelines structured as pass-through entities. FERC also indicated that it will incorporate the effects of the revised policy statement and the effects of the income tax rate reductions provided by the Tax Cuts and Jobs Act of 2017 in its review of the oil pipeline index level to be effective July 1, 2021. Depending on how FERC incorporates its most recent tax policy statement and the tax rate reduction into its next index review, which is scheduled to become effective in 2021, our ability to increase our index-based rates could be negatively impacted.

In addition, a state commission also could investigate our intrastate rates or our terms and conditions of service on its own initiative or at the urging of a shipper or other interested party. If a state commission found that our rates exceeded levels justified by our cost of service, the state commission could order us to reduce our rates. Any such reductions may result in lower revenues and cash flows if additional volumes and/or capacity are unavailable to offset such rate reductions.

- 30 -

Our pipelines that are not currently regulated by FERC or a state commission may in the future become subject to such regulation. They may become regulated through construction or acquisition of new facilities, a change in law, a change in the interpretation of existing law, or upon a shipper complaint.

HFC and Delek have agreed not to challenge, or to cause others to challenge or assist others in challenging, our tariff rates in effect during the terms of their respective pipelines and terminals agreements; however, other current or future shippers may still challenge our tariff rates.

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 impact of (and threat of future) terrorist attacks and domestic vandalism, on the energy transportation industry in general, and on us in particular, is unknown. Any attack on our facilities, those of our customers and, in some cases, those of other pipelines could have a material adverse effect on our business. Increased security measures taken by us as a precaution against possible terrorist attacks or domestic vandalism have resulted in increased costs to our business.

The U.S. government has issued public warnings that indicate that pipelines and other assets might be specific targets of terrorist organizations.  These potential targets might include our pipeline systems or operating systems and may affect our ability to operate or control our pipeline assets or our operations could be disrupted. The occurrence of one of these events could cause a substantial decrease in revenues, increased costs to respond or other financial loss, damage to reputation, increased regulation or litigation and or inaccurate information reported from our operations.  These developments may subject our operations to increased risks, as well as increased costs, and, depending on their ultimate magnitude, could have a material adverse effect on our business, results of operations and financial condition.

Uncertainty surrounding continued global hostilities or other sustained military campaigns, and the possibility that infrastructure facilities could be direct targets of, or indirect casualties of, an act of terror, may affect our operations in unpredictable ways, including disruptions of crude oil supplies and markets for refined products or instability in the financial markets that could restrict our ability to raise capital.

In addition, 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.

Adverse changes in our and/or our general partner's credit ratings and risk profile may negatively affect us.

Our ability to access capital markets is important to our ability to operate our business. Regional and national economic conditions, increased scrutiny of the energy industry and regulatory changes, as well as changes in our economic performance, could result in credit agencies reexamining our credit rating.

We are in compliance with all covenants or other requirements set forth in our Credit Agreement. Further, we do not have any rating downgrade triggers that would automatically accelerate the maturity dates of any debt.

While credit ratings reflect the opinions of the credit agencies issuing such ratings and may not necessarily reflect actual performance, a downgrade in our credit rating could affect adversely our ability to borrow on, renew existing, or obtain access to new financing arrangements, could increase the cost of such financing arrangements, could reduce our level of capital expenditures and could impact our future earnings and cash flows.

The credit and business risk profiles of our general partner, and of HFC as the indirect owner of our general partner, may be factors in credit evaluations of us as a master limited partnership due to the significant influence of our general partner and its indirect ownership over our business activities, including our cash distribution policy, acquisition strategy and business risk profile. Another factor that may be considered is the financial condition of our general partner and its owners, including the degree of their financial leverage and their dependence on cash flow from the partnership to service their indebtedness.

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

From time to time, we evaluate and acquire assets and businesses that we believe complement our existing assets and businesses. Acquisitions may require substantial capital or the incurrence of substantial indebtedness. Our capitalization and results of

- 31 -

operations may change significantly as a result of completed or future acquisitions. Acquisitions and business expansions involve numerous risks, including difficulties in the assimilation of the assets and operations of the acquired businesses, inefficiencies and difficulties that arise because of unfamiliarity with new assets and the businesses associated with them, and new geographic areas and the diversion of management's attention from other business concerns. Further, unexpected costs and challenges may arise whenever businesses with different operations or management are combined, and we may experience unanticipated delays in realizing the benefits of an acquisition. Also, following an acquisition, we may discover previously unknown liabilities associated with the acquired business or assets for which we have no recourse under applicable indemnification provisions.

We own certain of our systems through joint ventures, and our control of such systems is limited by provisions of the agreements we have entered into with our joint venture partners and by our percentage ownership in such joint ventures.

Although our subsidiary is the operator of the UNEV pipeline and we own a majority interest in the joint venture that owns the UNEV pipeline, the joint venture agreement for the UNEV pipeline generally requires consent of our joint venture partner(s) for specified extraordinary transactions, such as reversing the flow of the pipeline or increasing the fees paid to our subsidiary pursuant to the operating agreement. 

In addition, certain of our systems are operated by joint venture entities that we do not operate, or in which we do not have an ownership stake that permits us to control the business activities of the entity. We have limited ability to influence the business decisions of such joint venture entities.

Because we have partial ownership in the joint ventures, we may be unable to control the amount of cash we will receive from the operation and could be required to contribute significant cash to fund our share of their operations, which could adversely affect our ability to distribute cash to our unitholders.

If we are unable to complete capital projects at their expected costs or in a timely manner, if we incur increased maintenance or repair costs on assets, 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.

Delays or cost increases related to capital spending programs involving construction of new facilities (or improvements and increased maintenance or repair expenditures on our existing facilities) could adversely affect our ability to achieve forecasted operating results. Although we evaluate and monitor each capital spending project and try to anticipate difficulties that may arise, such delays or cost increases may arise as a result of numerous factors, such as:

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

• 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, terror or cyberattacks, domestic vandalism other events (such as equipment malfunctions, explosions, fires or 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 by, or disputes with, vendors, suppliers, contractors, or sub-contractors involved with a project.

For example, we may not be able to complete the construction of the Cushing Connect Pipeline within the approved budget.  Our joint venture partner shares in 10% of the construction cost overrun with us 50/50.  Any costs that exceed 10% of the budget are borne solely by us. 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.

We do not own all of the land on which our pipeline systems and other assets are located, which could result in disruptions to our operations. Additionally, a change in the regulations related to a state’s use of eminent domain could inhibit our ability to secure rights-of-way for future pipeline construction projects. Finally, certain of our assets are located on tribal lands.

We do not own all of the land on which our pipeline systems and other assets are located, and we are, therefore, subject to the risk of increased costs or more burdensome terms to maintain necessary land use. We obtain the right to construct and operate pipelines and other assets on land owned by third parties and government agencies for specified periods. If we were to lose these rights through an inability to renew leases, right-of-way contracts or similar agreements, we may be required to relocate our pipelines or other assets and our business could be adversely affected. Additionally, it may become more expensive for us to obtain new rights-of-way or leases or to renew existing rights-of-way or leases. If the cost of obtaining or renewing such agreements increases, it may adversely affect our operations and the cash flows available for distribution to unitholders.

- 32 -

The adoption or amendment of laws and regulations that limit or eliminate a state’s ability to exercise eminent domain over private property in a state in which we operate could make it more difficult or costly for us to secure rights-of-way for future pipeline construction and other projects.

Certain of our pipelines are located on Native American tribal lands. Various federal agencies, along with each Native American tribe, promulgate and enforce regulations, including environmental standards, regarding operations on Native American tribal lands. In addition, each Native American tribe is a sovereign nation having the right to enforce laws and regulations (including various taxes, fees, and other requirements and conditions) and to grant approvals independent from federal, state and local statutes and regulations. Following a recent decision issued in May 2017 by the federal Tenth Circuit Court of Appeals, tribal ownership of even a very small fractional interest in an allotted land, that is, tribal land owned or at one time owned by an individual Native American landowner, bars condemnation of any interest in the allotment.  Consequently, the inability to condemn such allotted lands under circumstances where existing pipeline rights-of-way may soon lapse or terminate serves as an additional impediment for pipeline operations.  These factors may increase our cost of doing business on Native American tribal lands.

In addition, our industry is subject to potentially disruptive activities by those concerned with the possible environmental impacts of pipeline routes. Activists, non-governmental organizations and others may seek to restrict the transportation of crude oil and refined products by exerting social or political pressure to influence when, and whether, such rights-of-way or permits are granted. This interference could impact future pipeline development, which could interfere with or block expansion or development projects and could have a material adverse effect on our business, financial condition, results of operations and our ability to make cash distributions to our unitholders.

Our business may suffer due to a change in the composition of our Board of Directors, if any of our key senior executives or other key employees who provide services to us discontinue employment, or if certain of our executive officers, who also allocate time to our general partner and its affiliates, do not have enough time to dedicate to our business. Furthermore, a shortage of skilled labor or disruptions in the labor force that provides services to us may make it difficult for us to maintain labor productivity.

Our future success depends to a large extent on the services of HLS's Board of Directors, key senior executives and key senior employees who provide services to us. Also, our business depends on the continuing ability to recruit, train and retain highly qualified employees in all areas of our operations, including accounting, business operations, finance and other key back-office and mid-office personnel. The competition for these employees is intense, and the loss of these executives or employees could harm our business. If any of these executives or other key personnel resign or become unable to continue in their present roles and are not adequately replaced, our business operations could be materially adversely affected. We do not maintain any “key person” life insurance for any executives. Furthermore, our operations require skilled and experienced laborers with proficiency in multiple tasks.

Our general partner shares officers and administrative personnel with HFC to operate both our business and HFC's business. These officers face conflicts regarding the allocation of their and other employees' time, which may affect adversely our results of operations, cash flows and financial condition.

A portion of HFC's employees that are seconded to us from time to time are represented by labor unions under collective bargaining agreements with various expiration dates. HFC may not be able to renegotiate the collective bargaining agreements when they expire on satisfactory terms or at all. A failure to do so may increase our costs. In addition, existing labor agreements may not prevent a future strike or work stoppage, and any work stoppage could negatively affect our results of operations and financial condition.

- 33 -

RISKS TO COMMON UNITHOLDERS

HFC and its affiliates may have conflicts of interest and limited fiduciary duties, which may permit them to favor their own interests.

Currently, HFC and certain of its subsidiaries collectively own a 57% limited partner interest and a non-economic general partner interest in us and controls HLS, the general partner of our general partner, HEP Logistics. Conflicts of interest may arise between HFC and its affiliates, including our general partner, on the one hand, and us, on the other hand. As a result of these conflicts, the general partner may favor its own interests and the interests of its other affiliates over our interests. These conflicts include, among others, the following situations:

• HFC, as a shipper on our pipelines, has an economic incentive not to cause us to seek higher tariff rates or terminalling fees, even if such higher rates or terminalling fees would reflect rates that could be obtained in arm's-length, third-party transactions;

• neither our partnership agreement nor any other agreement requires HFC to pursue a business strategy that favors us or utilizes our assets, including whether to increase or decrease refinery production, whether to shut down or reconfigure a refinery, or what markets to pursue or grow;

• HFC's directors and officers have a fiduciary duty to make business decisions in the best interests of the stockholders of HFC;

• our general partner is allowed to take into account the interests of parties other than us, such as HFC, in resolving conflicts of interest;

• our partnership agreement provides for modified or reduced fiduciary duties for our general partner, and also restricts the remedies available to our unitholders for actions that, without the limitations, might constitute breaches of fiduciary duty;

• our general partner determines which costs incurred by HFC and its affiliates are reimbursable by us;

• our partnership agreement does not restrict our general partner from causing us to pay it or its affiliates for any services rendered to us or entering into additional contractual arrangements with any of these entities on our behalf;

• our general partner may, in some circumstances, cause us to borrow funds to make cash distributions, even where the purpose or effect of the borrowing benefits our general partner or affiliates;

• our general partner determines the amount and timing of our asset purchases and sales, capital expenditures and borrowings, each of which can affect the amount of cash available to us; and

• our general partner controls the enforcement of obligations owed to us by our general partner and its affiliates, including the pipelines and terminals agreement with HFC.

Cost reimbursements, which will be determined by our general partner, and fees due to our general partner and its affiliates for services provided, are substantial.

Under our Omnibus Agreement, we are obligated to pay HFC an administrative fee of currently $2.6 million per year for the provision by HFC or its affiliates of various general and administrative services for our benefit. The administrative fee is subject to an annual upward adjustment for changes in PPI. In addition, we are required to reimburse HFC pursuant to the secondment arrangement for the wages, benefits, and other costs of HFC employees seconded to HLS to perform services at certain of our processing, refining, pipeline and tankage assets. We can neither provide assurance that HFC will continue to provide us the officers and employees that are necessary for the conduct of our business nor that such provision will be on terms that are acceptable to us. If HFC fails to provide us with adequate personnel, our operations could be adversely impacted.

The administrative fee and secondment allocations are subject to annual review and may increase if we make an acquisition that requires an increase in the level of general and administrative services that we receive from HFC or its affiliates. Our general partner will determine the amount of general and administrative expenses that will be allocated to us in accordance with the terms of our partnership agreement. In addition, our general partner and its affiliates are entitled to reimbursement for all other expenses they incur on our behalf, including the salaries of and the cost of employee benefits for employees of HLS who provide services to us.

Prior to making any distribution on the common units, we will reimburse our general partner and its affiliates, including officers and directors of the general partner, for all expenses incurred on our behalf, plus the administrative fee. The reimbursement of expenses and the payment of fees could adversely affect our ability to make distributions. The general partner has sole discretion to determine the amount of these expenses. Our general partner and its affiliates also may provide us other services for which we are charged fees as determined by our general partner.

- 34 -

Increases in interest rates could adversely impact our unit price and our ability to issue additional equity to make acquisitions, fund expansion capital expenditures, or for other purposes.

As with other yield-oriented securities, our unit price is impacted by the level of our cash distributions and implied distribution yield. The distribution yield is often used by investors to compare and rank related yield-oriented securities for investment decision-making purposes. Therefore, changes in interest rates, either positive or negative, may affect the yield requirements of investors who invest in our units and a rising interest rate environment could have an adverse impact on our unit price and our ability to issue additional equity to make acquisitions, fund expansion capital expenditures or for other purposes. If we then issue additional equity at a significantly lower price, material dilution to our existing unitholders could result.

Even if unitholders are dissatisfied, they cannot remove our general partner without its consent.

Unlike the holders of common stock in a corporation, unitholders have only limited voting rights on matters affecting our business and, therefore, limited ability to influence management's decisions regarding our business. Unitholders did not elect our general partner or the board of directors of HLS and have no right to do so on an annual or other continuing basis. The board of directors of HLS is chosen by the sole member of HLS. If unitholders are dissatisfied with the performance of our general partner, they will have little ability to remove our general partner. As a result of these limitations, the price at which the common units trade could be diminished because of the absence or reduction of a takeover premium in the trading price.

The vote of the holders of at least 66 2/3% of all outstanding units voting together as a single class is required to remove the general partner. Unitholders will be unable to remove the general partner without its consent because the general partner and its affiliates own sufficient units to prevent its removal. Unitholders' voting rights are further restricted by the partnership agreement provision providing that any units held by a person that owns 20% or more of any class of units then outstanding (other than the general partner, its affiliates, their transferees, and persons who acquired such units with the prior approval of the board of directors of the general partner's general partner) cannot vote on any matter; however, no such person currently exists. Our partnership agreement also contains provisions limiting the ability of unitholders to call meetings, acquire information about our operations, and influence the manner or direction of management.

The control of our general partner may be transferred to a third party without unitholder consent.

Our general partner may transfer its general partner interest to a third party in a merger or in a sale of all or substantially all of its assets without the consent of the unitholders. Furthermore, our partnership agreement does not restrict the ability of the partners of our general partner from transferring their respective partnership interests in our general partner to a third party. The new partners of our general partner would then be in a position to replace the board of directors and officers of the general partner of our general partner with their own choices and to control the decisions made by the board of directors and officers.

We may issue additional limited partner units without unitholder approval, which would dilute an existing unitholder's ownership interests.

Under our partnership agreement, provided there is no significant decrease in our operating performance, we may issue an unlimited number of limited partner interests of any type without the approval of our unitholders, and HEP currently has a shelf registration on file with the SEC pursuant to which it may issue up to $2.0 billion in additional common units. On May 10, 2016, HEP established a continuous offering program under the shelf registration statement pursuant to which HEP may issue and sell common units from time to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million. As of December 31, 2019, HEP has issued 2.4 million units under this program for gross consideration of $82.3 million.

The issuance by us of additional common units or other equity securities of equal or senior rank will have the following effects:

• our unitholders' proportionate ownership interest in us will decrease;

• the amount of cash available for distribution on each unit may decrease;

• the relative voting strength of each previously outstanding unit may be diminished; and

• the market price of the common units may decline.

Our partnership agreement does not give our unitholders the right to approve our issuance of equity securities ranking junior to the common units at any time.

- 35 -

In establishing cash reserves, our general partner may reduce the amount of cash available for distribution to unitholders.

Our partnership agreement requires us to distribute all available cash to our unitholders; however, it also requires our general partner to deduct from operating surplus cash reserves that it establishes are necessary to fund our future operating expenditures. In addition, our partnership agreement permits our general partner to reduce available cash by establishing cash reserves for the proper conduct of our business, to comply with applicable law or agreements to which we are a party, or to provide funds for future distributions to partners. These cash reserves will affect the amount of cash available to make the required payments to our debt holders or distributions on our common units every quarter.

HFC and its affiliates may engage in limited competition with us.

HFC and its affiliates may engage in limited competition with us. Pursuant to the Omnibus Agreement, HFC and its affiliates agreed not to engage in the business of operating intermediate or refined product pipelines or terminals, crude oil pipelines or terminals, truck racks or crude oil gathering systems in the continental United States. The Omnibus Agreement, however, does not apply to:

• any business operated by HFC or any of its subsidiaries at the closing of our initial public offering;

• any business or asset that HFC or any of its subsidiaries acquires or constructs that has a fair market value or construction cost of less than $5 million; and

• any business or asset that HFC or any of its subsidiaries acquires or constructs that has a fair market value or construction cost of $5 million or more if we have been offered the opportunity to purchase the business or asset at fair market value, and we decline to do so.

In the event that HFC or its affiliates no longer control our partnership or there is a change of control of HFC, the non-competition provisions of the Omnibus Agreement will terminate.

Our general partner has a limited call right that may require a unitholder to sell its common units at an undesirable time or price.

If at any time our general partner and its affiliates own more than 80% of the common units (which it does not presently), our general partner will have the right (which it may assign to any of its affiliates or to us) but not the obligation to acquire all, but not less than all, of the common units held by unaffiliated persons at a price not less than their then-current market price. As a result, a holder of common units may be required to sell its units at a time or price that is undesirable to it and may not receive any return on its investment. A common unitholder may also incur a tax liability upon a sale of its units.

A unitholder may not have limited liability if a court finds that unitholder actions constitute control of our business or that we have not complied with state partnership law.

Under Delaware law, a unitholder could be held liable for our obligations to the same extent as a general partner if a court determined that the right of unitholders to remove our general partner or to take other action under our partnership agreement constituted participation in the “control” of our business. Our general partner generally has unlimited liability for our obligations, such as our debts and environmental liabilities, except for those contractual obligations that are expressly made without recourse to our general partner.

In addition, Section 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act provides that under some circumstances, a unitholder may be liable to us for the amount of a distribution for a period of three years from the date of the distribution.

Further, we conduct business in a number of states. In some of those states the limitations on the liability of limited partners for the obligations of a limited partnership have not been clearly established. The unitholders might be held liable for the partnership's obligations as if they were a general partner if a court or government agency determined that we were conducting business in the state but had not complied with the state's partnership statute.

HFC may sell units in the public or private markets, and such sales could have an adverse impact on the trading price of the common units. Additionally, HFC may pledge or hypothecate its common units or its interest in us.

HFC currently holds 59,630,030 of our common units, which is approximately 57% of our outstanding common units. The sale of these units in the public or private markets could have an adverse impact on the trading price of our common units. Additionally,

- 36 -

we agreed to provide HFC registration rights with respect to our common units that it holds. HFC may pledge or hypothecate its common units, and such pledge or hypothecation may include terms and conditions that might result in an adverse impact on the trading price of our common units.

TAX RISKS TO COMMON UNITHOLDERS

Our tax treatment depends on our status as a partnership for federal income tax purposes as well as us not being subject to a material amount of entity-level taxation by individual states. If the U.S. Internal Revenue Service (the “IRS”) were to treat us as a corporation for federal income tax purposes or if we were to become subject to additional amounts of entity-level taxation for federal or state tax purposes, our cash available for distribution to our unitholders would be substantially reduced.

The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for federal income tax purposes.

Despite the fact that we are organized as a limited partnership under Delaware law, we would be treated as a corporation for federal income tax purposes unless we satisfy a "qualifying income" requirement. Based upon our current operations and current Treasury Regulations, we believe we satisfy the qualifying income requirement. Failing to meet the qualifying income requirement, or a change in current law could cause us to be treated as a corporation for federal income tax purposes or otherwise subject us to taxation as an entity.

If we were treated as a corporation for federal income tax purposes, we would pay federal income tax on our taxable income at the corporate tax rate. Distributions to unitholders would generally be taxed again as corporate distributions, and no income, gains, losses or deductions would flow through to unitholders. Because a tax would be imposed upon us as a corporation, our cash available for distribution to unitholders would be substantially reduced. Therefore, treatment of us as a corporation would result in a material reduction in the anticipated cash flow and after-tax return to unitholders, likely causing a substantial reduction in the value of our common units.

At the entity level, were we to be subject to federal income tax, we would also be subject to the income tax provisions of many states. Moreover, states are evaluating ways to independently subject partnerships to entity-level taxation through the imposition of state income taxes, franchise taxes and other forms of taxation. For example, we are required to pay Texas margin tax on any income apportioned to Texas. Imposition of any additional such taxes on us or an increase in the existing tax rates would reduce the cash available for distributions to our unitholders. Our partnership agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporation or otherwise subjects us to entity-level taxation for federal, state or local income tax purposes, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact of that law on us.

The tax treatment of publicly traded partnerships or an investment in our common units could be subject to potential legislative, judicial or administrative changes or differing interpretations, possibly applied on a retroactive basis.

The present federal income tax treatment of publicly traded partnerships, including us, or an investment in our common units may be modified by administrative, legislative or judicial changes and differing interpretations at any time. From time to time, members of Congress propose and consider similar substantive changes to the existing federal income tax laws that would affect publicly traded partnerships, including elimination of partnership tax treatment for certain publicly traded partnerships. For example, the “Clean Energy for America Act”, which is similar to legislation that was commonly proposed during the Obama Administration, was introduced in the Senate on May 2, 2019. If enacted, this proposal would, among other things, repeal the qualifying income exception within Section 7704(d)(1)(E) of the Code upon which we rely for our treatment as a partnership for federal income tax purposes.

In addition, the Treasury Department has issued, and in the future may issue, regulations interpreting those laws that affect publicly traded partnerships. There can be no assurance that there will not be further changes to U.S. federal income tax laws or the Treasury Department’s interpretation of the qualifying income rules in a manner that could impact our ability to qualify as a partnership in the future, which could also negatively impact the value of an investment in our common units. Any modification to the federal income tax laws and interpretations thereof may be applied retroactively and could make it more difficult or impossible for us to meet the qualifying income requirement to be treated as a partnership for U.S. federal income tax purposes. You are urged to consult with your own tax advisor with respect to the status of legislative, regulatory or administrative developments and proposals and their potential effect on your investment in our common units.

If the IRS contests the federal income tax positions we take, the market for our common units may be adversely impacted and the cost of any IRS contest will reduce our cash available for distribution to our unitholders.

The IRS may adopt positions that differ from the positions we have taken or may take on tax matters. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take. A court may not agree with some or all of the positions we take. Any contest with the IRS may materially and adversely impact the market for our common units and the price at which they trade. In addition, the costs of any contest with the IRS will be borne indirectly by our unitholders and our general partner because the costs will reduce our cash available for distribution.

If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us, in which case our cash available for distribution to our unitholders might be substantially reduced, and our current and former unitholders may be required to indemnify us for any taxes (including any applicable penalties and interest) resulting from such audit adjustments that were paid on their behalf.

Pursuant to the Bipartisan Budget Act of 2015, for tax years beginning after December 31, 2017, if the IRS makes audit adjustments to our income tax returns, it (and some states) may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us. Under our partnership agreement, our general partner is permitted to make elections under the new rules to either pay the taxes (including any applicable penalties and interest) directly to the IRS or, if we are eligible, issue a revised information statement to each affected current and former unitholder with respect to an audited and adjusted return. Although our general partner may elect to have our affected current and former unitholders take such audit adjustment into account and pay any resulting taxes (including any applicable penalties and interest) in accordance with their interests in us during the tax year under audit, there can be no assurance that such election will be practical, permissible or effective in all circumstances. As a result, our current unitholders may bear some or all of the tax liability resulting from such audit adjustment, even if such unitholders did not own units in us during the tax year under audit. If, as a result of any such audit adjustment, we are required to make payments of taxes, penalties or interest, our cash available for distribution to our unitholders might be substantially reduced, and our current and former unitholders may be required to indemnify us for any taxes (including any applicable penalties and interest) resulting from such audit adjustments that were paid on their behalf. These rules are not applicable for tax years beginning on or prior to December 31, 2017.

Even if unitholders do not receive any cash distributions from us, they will be required to pay taxes on their share of our taxable income.

Unitholders will be required to pay federal income taxes and, in some cases, state and local income taxes, on their share of our taxable income, whether or not they receive cash distributions from us. For example, if we sell assets and use the proceeds to repay existing debt or fund capital expenditures, unitholders may be allocated taxable income and gain resulting from the sale and our cash available for distribution would not increase. Similarly, taking advantage of opportunities to reduce our existing debt, such as debt exchanges, debt repurchases, or modifications of our existing debt, could result in “cancellation of indebtedness income” being allocated to unitholders as taxable income without any increase in our cash available for distribution. Unitholders may not receive cash distributions from us equal to their share of our taxable income or even equal to the actual tax due from the unitholder with respect to that income.

Tax gain or loss on the disposition of our common units could be more or less than expected.

If a unitholder disposes of common units, it will recognize gain or loss equal to the difference between the amount realized and its tax basis in those common units. Because distributions in excess of a unitholder's allocable share of our net taxable income result in a decrease of the unitholder's tax basis in its common units, the amount, if any, of such prior excess distributions with respect to the units sold will, in effect, become taxable income to the unitholder if it sells such units at a price greater than its tax basis in those units, even if the price the unitholder receives is less than its original cost. In addition, because the amount realized includes a unitholder's share of our nonrecourse liabilities, if unitholders sell their units, they may incur a tax liability in excess of the amount of cash they receive from the sale.

A substantial portion of the amount realized from the sale of a unitholder's common units, whether or not representing gain, may be taxed as ordinary income to the unitholder due to potential recapture items, including depreciation recapture. Thus, the unitholder may recognize both ordinary income and capital loss from the sale of such units if the amount realized on a sale of such units is less than the unitholder's adjusted basis in the units. Net capital loss may only offset capital gains and, in the case of individuals, up to $3,000 of ordinary income per year. In the taxable period in which the unitholder sells its units, the unitholder may recognize ordinary income from our allocations of income and gain to the unitholder prior to the sale and from recapture items that generally cannot be offset by any capital loss recognized upon the sale of units.

- 38 -

Unitholders may be subject to limitation on their ability to deduct interest expense incurred by us.

In general, we are entitled to a deduction for interest paid or accrued on indebtedness properly allocable to our trade or business during our taxable year. However, under the Tax Cuts and Jobs Act, for taxable years beginning after December 31, 2017, our deduction for “business interest” is limited to the sum of our business interest income and 30% of our “adjusted taxable income.” For the purposes of this limitation, our adjusted taxable income is computed without regard to any business interest expense or business interest income, and in the case of taxable years beginning before January 1, 2022, any deduction allowable for depreciation, amortization, or depletion to the extent such depreciation, amortization, or depletion is not capitalized into cost of goods sold with respect to inventory. If this limitation were to apply with respect to a taxable year, it could result in an increase in the taxable income allocable to a unitholder for such taxable year without any corresponding increase in the cash available for distribution to such unitholder.

Tax-exempt entities face unique tax issues from owning our common units that may result in adverse tax consequences to them.

Investment in our common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts (known as IRAs) raises issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from U.S. federal income tax, including IRAs and other retirement plans, will be unrelated business taxable income and will be taxable to them. With respect to taxable years beginning after December 31, 2017, subject to the proposed aggregation rules for certain similarly situated businesses or activities issued by the Treasury Department, a tax-exempt entity with more than one unrelated trade or business (including by attribution from investment in a partnership such as ours) is required to compute the unrelated business taxable income of such tax-exempt entity separately with respect to each such trade or business (including for purposes of determining any net operating loss deduction). As a result, for years beginning after December 31, 2017, it may not be possible for tax-exempt entities to utilize losses from an investment in our partnership to offset unrelated business taxable income from another unrelated trade or business and vice versa. Tax-exempt entities should consult a tax advisor before investing in our common units.

Non-U.S. unitholders will be subject to U.S. taxes and withholding with respect to their income and gain from owning our units.

Non-U.S. unitholders are generally taxed and subject to U.S. income tax filing requirements on income effectively connected with a U.S. trade or business (“effectively connected income”). Income allocated to our unitholders and any gain from the sale of our units will generally be considered to be “effectively connected” with a U.S. trade or business. As a result, distributions to a non-U.S. unitholder will be subject to withholding at the highest applicable effective tax rate, and a non-U.S. unitholder who sells or otherwise disposes of a unit will also be subject to U.S. federal income tax on the gain realized from the sale or disposition of that unit.

Moreover, the transferee of an interest in a partnership that is engaged in a U.S. trade or business is generally required to withhold 10% of the amount realized by the transferor unless the transferor certifies that it is not a foreign person, and we are required to deduct and withhold from the transferee amounts that should have been withheld by the transferees but were not withheld. Because the “amount realized” includes a partner’s share of the partnership’s liabilities, 10% of the amount realized could exceed the total cash purchase price for the units. However, pending the issuance of final regulations, the IRS has suspended the application of this withholding rule to transfers of publicly traded interests in publicly traded partnerships. If recently promulgated regulations are finalized as proposed, such regulations would provide, with respect to transfers of publicly traded interests in publicly traded partnerships effected through a broker, that the obligation to withhold is imposed on the transferor’s broker and that a partner’s “amount realized” does not include a partner’s share of a publicly traded partnership’s liabilities for purposes of determining the amount subject to withholding. However, it is not clear when such regulations will be finalized or if they will be finalized in their current form.

We treat each purchaser of common units as having the same tax benefits without regard to the actual common units purchased. The IRS may challenge this treatment, which could adversely affect the value of the common units.

Because we cannot match transferors and transferees of common units and because of other reasons, we have adopted depreciation and amortization positions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to our unitholders. It also could affect the timing of these tax benefits or the amount of gain from unitholders' sale of common units and could have a negative impact on the value of our common units or result in audit adjustments to their tax returns.

- 39 -

We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our unitholders.

We generally prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month (the "Allocation Date") based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. Similarly, we generally allocate certain deductions for depreciation of capital additions, gain or loss realized on a sale or other disposition of our assets and, in the discretion of the general partner, any other extraordinary item of income, gain, loss or deduction based upon ownership on the Allocation Date. Treasury Regulations allow a similar monthly simplifying convention, but such regulations do not specifically authorize all aspects of our proration method. If the IRS were to challenge our proration method, we may be required to change the allocation of items of income, gain, loss and deduction among our unitholders.

A unitholder whose units are the subject of a securities loan (e.g., a loan to a “short seller” to cover a short sale of units) may be considered as having disposed of those units. If so, it would no longer be treated for tax purposes as a partner with respect to those units during the period of the loan and may recognize gain or loss from the disposition.

Because there are no specific rules governing the federal income tax consequences of loaning a partnership interest, a unitholder whose units are the subject of a securities loan may be considered as having disposed of the loaned units. In that case, such unitholder may no longer be treated for tax purposes as a partner with respect to those units during the period of the loan to the short seller and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan, any of our income, gain, loss or deduction with respect to those units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those units could be fully taxable as ordinary income. Unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a securities loan are urged to modify any applicable brokerage account agreements to prohibit their brokers from borrowing their units.

We have adopted certain valuation methodologies in determining a unitholder's allocations of income, gain, loss and deduction. The IRS may challenge these methodologies or the resulting allocations, which could adversely affect the value of our common units.

In determining the items of income, gain, loss and deduction allocable to our unitholders, we must routinely determine the fair market value of our assets. Although we may, from time to time, consult with professional appraisers regarding valuation matters, we make many fair market value estimates using a methodology based on the market value of our common units as a means to measure the fair market value of our assets. The IRS may challenge these valuation methods and the resulting allocations of income, gain, loss and deduction.

A successful IRS challenge to these methods or allocations could adversely affect the amount of taxable income or loss being allocated to our unitholders. It also could affect the amount of gain recognized from our unitholders' sale of common units and could have a negative impact on the value of the common units or result in audit adjustments to our unitholders' tax returns without the benefit of additional deductions.

Unitholders likely will be subject to state and local taxes and return filing requirements as a result of investing in our common units.

In addition to federal income taxes, unitholders likely will be subject to other taxes, such as state and local income taxes, unincorporated business taxes and estate, inheritance, or intangible taxes that are imposed by the various jurisdictions in which we do business or own property now or in the future. Unitholders likely will be required to file state and local income tax returns and pay state and local income taxes in some or all of these various jurisdictions, even if they do not live in these jurisdictions. Further, unitholders may be subject to penalties for failure to comply with those requirements. We currently own property and conduct business in Texas, New Mexico, Utah, Idaho, Oklahoma, Washington, Kansas, Wyoming and Nevada. We may own property or conduct business in other states or foreign countries in the future. It is the unitholder's responsibility to file all federal, state, local and foreign tax returns.

Item 1B. Unresolved Staff Comments

We do not have any unresolved SEC staff comments.

Item 3. Legal Proceedings

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

Item 4. Mine Safety Disclosures

Not applicable.

PART II

Item 5. Market for the Registrant’s Common Units, Related Unitholder Matters and Issuer Purchases of Common Units

Our common limited partner units are traded on the New York Stock Exchange under the symbol “HEP.”

As of February 13, 2020, we had approximately 17,169 common unitholders, including beneficial owners of common units held in street name.

We consider regular cash distributions to unitholders on a quarterly basis, although there is no assurance as to the future cash distributions since they are dependent upon future earnings, cash flows, capital requirements, financial condition and other factors. See “Liquidity and Capital Resources” under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for a discussion of conditions and limitations prohibiting distributions under the Credit Agreement and indentures relating to our senior notes.

Common Unit Repurchases Made in the Quarter

The following table discloses purchases of our common units made by us or on our behalf for the periods shown below:

Period	Total Number of Units Purchased	Average Price Paid Per Unit		Total Number of Units Purchased as Part of Publicly Announced Plan or Program	Maximum Number of Units that May Yet be Purchased Under a Publicly Announced Plan or Program
October 2019	—	$	—	—	$	—
November 2019	54,106	$	22.46	—	$	—
December 2019	13,822	$	22.00	—	$	—
Total for October to December 2019	67,928			—

The units reported represent (a) purchases of 54,106 common units in the open market for delivery to the recipients of our restricted unit, phantom unit and performance unit awards under our Long-Term Incentive Plan at the time of grant or settlement, as applicable; and (b) the delivery of 13,822 common units (which units were previously issued to certain officers and other employees pursuant to restricted unit awards or phantom unit awards at the time of grant or settlement, as applicable) by such officers and employees to provide funds for the payment of payroll and income taxes due at vesting in the case of officers and employees who did not elect to satisfy such taxes by other means.

Item 6. Selected Financial Data

The following table shows selected financial information from the consolidated financial statements of HEP and from the financial statements of our Predecessor (defined below). We acquired assets from HFC, including El Dorado Operating on November 1, 2015, crude tanks at HFC's Tulsa refinery on March 31, 2016 and Woods Cross Operating on October 1, 2016. As we are a variable interest entity controlled by HFC, these acquisitions were accounted for as transfers between entities under common control. Accordingly, this financial data includes the historical results of these acquisitions for all periods presented prior to the effective dates of each acquisition. We refer to these historical results as those of our "Predecessor." See Note 2 in notes to consolidated financial statements of HEP for further discussion of these acquisitions.

This table should be read in conjunction with Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements of HEP and related notes thereto included elsewhere in this Form 10-K.

(1) Net income attributable to the partners is allocated between limited partners and the general partner interest in accordance with the provisions of the partnership agreement. HEP net income allocated to the general partner included incentive distributions that were declared subsequent to quarter end. After the amount of incentive distributions and other priority allocations are allocated to the general partner, the remaining net income attributable to the partners is allocated to the partners based on their weighted average ownership percentage during the period. As a result of the IDR Restructuring Transaction, no IDR or general partner distributions were made after October 31, 2017. See "Business and Properties - Overview."

- 44 -

(2) Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is calculated as net income attributable to Holly Energy Partners plus (i) interest expense, net of interest income, (ii) state income tax and (iii) depreciation and amortization. Adjusted EBITDA is calculated as EBITDA minus (i) gain on sales-type leases and (ii) pipeline lease payments not included in operating costs and expenses plus (iii) loss on early extinguishment of debt and (iv) pipeline tariffs not included in revenues due to impacts from lease accounting. Portions of our minimum guaranteed pipeline tariffs for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. These pipeline tariffs were previously recorded as revenues prior to the renewal of the throughput agreement, which triggered sales-type lease accounting. Similarly, certain pipeline lease payments were previously recorded as operating costs and expenses, but the underlying lease was reclassified from an operating lease to a financing lease, and these payments are now recoded as interest expense and reductions in the lease liability. EBITDA and Adjusted EBITDA are not calculations based upon generally accepted accounting principles ("GAAP"). However, the amounts included in the EBITDA and Adjusted EBITDA calculations are derived from amounts included in our consolidated financial statements. EBITDA and Adjusted EBITDA should not be considered as alternatives to net income attributable to Holly Energy Partners or operating income, as indications of our operating performance or as alternatives to operating cash flow as a measure of liquidity. EBITDA and Adjusted EBITDA are not necessarily comparable to similarly titled measures of other companies. EBITDA and Adjusted EBITDA are presented here because they are widely used financial indicators used by investors and analysts to measure performance. EBITDA and Adjusted EBITDA are also used by our management for internal analysis and as a basis for compliance with financial covenants.

Set forth below is our calculation of EBITDA.

(3) Distributable cash flow is not a calculation based upon GAAP. However, the amounts included in the calculation are derived from amounts presented in our consolidated financial statements, with the general exception of maintenance capital expenditures. Distributable cash flow should not be considered in isolation or 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. Distributable cash flow is not necessarily comparable to similarly titled measures of other companies. Distributable cash flow is presented here because it is a widely accepted financial indicator used by investors to compare partnership performance. It is also used by management for internal analysis and for our performance units. We believe that this measure provides investors an enhanced perspective of the operating performance of our assets and the cash our business is generating.

(4) Maintenance capital expenditures are capital expenditures made to replace partially or fully depreciated assets in order to maintain the existing operating capacity of our assets and to extend their useful lives. Maintenance capital expenditures include expenditures required to maintain equipment reliability, tankage and pipeline integrity, safety and to address environmental regulations.

(5) Includes $965.5 million, $923 million, $1,012 million, $553 million and $712 million in Credit Agreement advances that were classified as long-term debt at December 31, 2019, 2018, 2017, 2016 and 2015, respectively.

(6) As a master limited partnership, we distribute our available cash, which historically has exceeded our net income attributable to the partners because depreciation and amortization expense represents a non-cash charge against income. The result is a decline in partners’ equity since our regular quarterly distributions have exceeded our quarterly net income attributable to partners. Additionally, if the assets contributed and acquired from HFC while we were a consolidated variable interest entity of HFC had been acquired from third parties, our acquisition cost in excess of HFC’s basis in the transferred assets would have been recorded in our financial statements as increases to our properties and equipment and intangible assets at the time of acquisition instead of decreases to partners’ equity.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Item 7, including but not limited to the sections on “Liquidity and Capital Resources,” contains forward-looking statements. See “Forward-Looking Statements” at the beginning of Part I and Item 1A. “Risk Factors.” In this document, the words “we,” “our,” “ours” and “us” refer to HEP and its consolidated subsidiaries or to HEP or an individual subsidiary and not to any other person.

OVERVIEW

HEP is a Delaware limited partnership. Through our subsidiaries and joint ventures we own and/or operate petroleum product and crude oil pipelines, terminal, tankage and loading rack facilities and refinery processing units that support the refining and marketing operations of HFC and other refineries in the Mid-Continent, Southwest and Northwest regions of the United States and Delek’s refinery in Big Spring, Texas. HEP, through its subsidiaries and joint ventures, owns and/or operates petroleum product and crude pipelines, tankage and terminals in Texas, New Mexico, Washington, Idaho, Oklahoma, Utah, Nevada, Wyoming and Kansas as well as refinery processing units in Utah and Kansas. HFC owned 57% of our outstanding common units and the non-economic general partner interest as of December 31, 2019.

We generate revenues by charging tariffs for transporting petroleum products and crude oil through our pipelines, by charging fees for terminalling and storing refined products and other hydrocarbons, providing other services at our storage tanks and terminals and charging a tolling fee per barrel or thousand standard cubic feet of feedstock throughput in our refinery processing units. We do not take ownership of products that we transport, terminal or store, and therefore we are not directly exposed to changes in commodity prices.

We believe the long-term growth of global refined product demand and US crude production should support high utilization rates for the refineries we serve, which in turn will support volumes in our product pipelines, crude gathering system and terminals.

Acquisitions

On October 31, 2017, we acquired the remaining 75% interest in SLC Pipeline and the remaining 50% interest in Frontier Aspen from subsidiaries of Plains, for cash consideration of $250 million. Prior to this acquisition, we held noncontrolling interests of 25% of SLC Pipeline and 50% of Frontier Aspen. As a result of the acquisitions, SLC Pipeline and Frontier Aspen are wholly-owned subsidiaries of HEP.

This acquisition was accounted for as a business combination achieved in stages with the consideration allocated to the acquisition date fair value of assets and liabilities acquired. The preexisting equity interests in SLC Pipeline and Frontier Aspen were remeasured at acquisition date fair value since we will have a controlling interest, and we recognized a gain on the remeasurement in the fourth quarter of 2017 of $36.3 million.

SLC Pipeline is the owner of a 95-mile crude pipeline that transports crude oil into the Salt Lake City area from the Utah terminal of the Frontier Pipeline and from Wahsatch Station. Frontier Aspen is the owner of a 289-mile crude pipeline from Casper, Wyoming to Frontier Station, Utah that supplies Canadian and Rocky Mountain crudes to Salt Lake City area refiners through a connection to the SLC Pipeline.

Investment in Joint Venture

On October 2, 2019, HEP Cushing LLC (“HEP Cushing”), a wholly-owned subsidiary of HEP, and Plains Marketing, L.P., a wholly-owned subsidiary of Plains, formed a 50/50 joint venture, Cushing Connect Pipeline & Terminal LLC (the “Cushing Connect Joint Venture”), for (i) the development and construction of a new 160,000 barrel per day common carrier crude oil pipeline (the “Cushing Connect Pipeline”) that will connect the Cushing, Oklahoma crude oil hub to the Tulsa, Oklahoma refining complex owned by a subsidiary of HFC and (ii) the ownership and operation of 1.5 million barrels of crude oil storage in Cushing, Oklahoma (the “Cushing Connect JV Terminal”). The Cushing Connect JV Terminal is expected to be placed in service during the second quarter of 2020, and the Cushing Connect Pipeline is expected to be placed in service during the first quarter of 2021. Long-term commercial agreements have been entered into to support the Cushing Connect Joint Venture assets.

The Cushing Connect Joint Venture has contracted with an affiliate of HEP to manage the construction and operation of the Cushing Connect Pipeline and with an affiliate of Plains to manage the operation of the Cushing Connect JV Terminal. The total Cushing Connect Joint Venture investment will generally be shared equally among HEP and Plains, and HEP estimates its share of the cost of the Cushing Connect JV Terminal contributed by Plains and Cushing Connect Pipeline construction costs are approximately $65 million. However, any Cushing Connect Pipeline construction costs exceeding 10% of the budget are borne solely by us.

Agreements with HFC and Delek

We serve HFC's refineries under long-term pipeline, terminal, tankage and refinery processing unit throughput agreements expiring from 2021 to 2036. Under these agreements, HFC agrees to transport, store, and process throughput volumes of refined product, crude oil and feedstocks on our pipelines, terminal, tankage, loading rack facilities and refinery processing units that result in minimum annual payments to us. These minimum annual payments or revenues are subject to annual rate adjustments on July 1st each year based on the PPI or the FERC index. As of December 31, 2019, these agreements with HFC require minimum annualized payments to us of $348 million.

If HFC fails to meet its minimum volume commitments under the agreements in any quarter, it will be required to pay us the amount of any shortfall in cash by the last day of the month following the end of the quarter. Under certain of the agreements, a shortfall payment may be applied as a credit in the following four quarters after minimum obligations are met.

A significant reduction in revenues under the HFC agreements could have a material adverse effect on our results of operations.

We have a pipelines and terminals agreement with Delek expiring in 2020 under which Delek has agreed to transport on our pipelines and throughput through our terminals volumes of refined products that result in a minimum level of annual revenue that also is subject to annual tariff rate adjustments. On September 30, 2019, Delek exercised its first renewal option (the “Renewal”) under this agreement for an additional five year period beginning April 1, 2020, but only with respect to specific assets. For the refined product pipelines and refined product terminals that were not subject to the Renewal and which currently account for approximately $15 million to $16 million of HEP’s annual revenues from Delek, the agreement terminates as of March 31, 2020. In light of this development, we are exploring other potential options with respect to the pipeline and terminal assets that were not subject to the Renewal.

We also have a capacity lease agreement under which we lease space to Delek on our Orla to El Paso pipeline for the shipment of refined product. The terms for a portion of the capacity under this lease agreement expired in 2018 and were not renewed, and the remaining portions of the capacity expire in 2020 and 2022.

As of December 31, 2019, these agreements with Delek require minimum annualized payments to us of $32 million before considering the refined product pipelines and refined product terminals that were not subject to the Renewal.

Under certain provisions of an omnibus agreement that we have with HFC (“Omnibus Agreement”), we pay HFC an annual administrative fee ($2.6 million in 2019), for the provision by HFC or its affiliates of various general and administrative services to us. This fee does not include the salaries of personnel employed by HFC who perform services for us on behalf of HLS or the cost of their employee benefits, which are separately charged to us by HFC. We also reimburse HFC and its affiliates for direct expenses they incur on our behalf.

Under HLS’s Secondment Agreement with HFC, certain employees of HFC are seconded to HLS to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs of these employees for our benefit.

We have a long-term strategic relationship with HFC. Our current growth plan is to continue to pursue purchases of logistic and other assets at HFC's existing refining locations in New Mexico, Utah, Oklahoma, Kansas and Wyoming. We also expect to work with HFC on logistic asset acquisitions in conjunction with HFC’s refinery acquisition strategies. Furthermore, we plan to continue to pursue third-party logistic asset acquisitions that are accretive to our unitholders and increase the diversity of our revenues.

(1) Net income attributable to the partners is allocated between limited partners and the general partner interest in accordance with the provisions of the partnership agreement. HEP net income allocated to the general partner included incentive distributions that were declared subsequent to quarter end. After the amount of incentive distributions and other priority allocations are allocated to the general partner, the remaining net income attributable to the partners is allocated to the partners based on their weighted average ownership percentage during the period. As a result of the IDR Restructuring Transaction, no IDR or general partner distributions were made after October 31, 2017. See "Business and Properties - Overview."

(2) Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is calculated as net income attributable to Holly Energy Partners plus (i) interest expense, net of interest income, (ii) state income tax and (iii) depreciation and amortization. Adjusted EBITDA is calculated as EBITDA minus (i) gain on sales-type leases and (ii) pipeline lease payments not included in operating costs and expenses plus (iii) pipeline tariffs not included in revenues due to impacts from lease accounting. Portions of our minimum guaranteed pipeline tariffs for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. These pipeline tariffs were previously recorded as revenues prior to the renewal of the throughput agreement, which triggered sales-type lease accounting. Similarly, certain pipeline lease payments were previously recorded as operating costs and expenses, but the underlying lease was reclassified from an operating lease to a financing lease, and these payments are now recoded as interest expense and reductions in the lease liability. EBITDA and Adjusted EBITDA are not calculations based upon generally accepted accounting principles ("GAAP"). However, the amounts included in the EBITDA and Adjusted EBITDA calculations are derived from amounts included in our consolidated financial statements. EBITDA and Adjusted EBITDA should not be considered as alternatives to net income attributable to Holly Energy Partners or operating income, as indications of our operating performance or as alternatives to operating cash flow as a measure of liquidity. EBITDA and Adjusted EBITDA are not necessarily comparable to similarly titled measures of other companies. EBITDA and Adjusted EBITDA are presented here because they are widely used financial indicators used by investors and analysts to measure performance. EBITDA and Adjusted EBITDA are also used by our management for internal analysis and as a basis for compliance with financial covenants. See our calculation of EBITDA under Item 6, “Selected Financial Data.”

(3) Distributable cash flow is not a calculation based upon GAAP. However, the amounts included in the calculation are derived from amounts presented in our consolidated financial statements, with the general exception of maintenance capital expenditures. Distributable cash flow should not be considered in isolation or 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. Distributable cash flow is not necessarily comparable to similarly titled measures of other companies. Distributable cash flow is presented here because it is a widely accepted financial indicator used by investors to compare partnership performance. It is also used by management for internal analysis and for our performance units. We believe that this measure provides investors an enhanced perspective of the operating performance of our assets and the cash our business is generating. See our calculation of distributable cash flow under Item 6, “Selected Financial Data.”

Results of Operations — Year Ended December 31, 2019 Compared with Year Ended December 31, 2018

Summary

Net income attributable to the partners for the year ended December 31, 2019, was $224.9 million, a $46.0 million increase compared to the year ended December 31, 2018. During the third quarter of 2019, HEP and HFC renewed the original throughput agreement on specific HEP assets. Portions of the new throughput agreement met the definition of sales-type leases, which resulted in an accounting gain of $35.2 million upon the initial recognition of the sales-type leases during the third quarter. Excluding this gain, net income attributable to the partners was $189.7 million ($1.80 per basic and diluted limited partner unit), an increase of $10.9 million compared to the same period of 2018. The increase was mainly attributable to higher crude oil pipeline volumes around the Permian Basin and our crude pipeline systems in Wyoming and Utah, higher revenues on our refinery processing units and contractual tariff escalators, partially offset by higher operating costs and expenses.

Revenues

Revenues for the year ended December 31, 2019, were $532.8 million, a $26.6 million increase compared to the same period in 2018. The increase was mainly attributable to higher crude oil pipeline volumes around the Permian Basin and our crude pipeline systems in Wyoming and Utah, higher revenues on our refinery processing units and contractual tariff escalators.

Revenues from our refined product pipelines were $132.4 million, a decrease of $5.2 million, on shipments averaging 195.5 mbpd compared to 199.6 mbpd for the year ended December 31, 2018. The revenue decrease was mainly due to a reclassification of

- 51 -

some pipeline tariffs from revenue to interest income under sales-type lease accounting as well as lower volumes on pipelines servicing HollyFrontier's Navajo refinery partially offset by higher volumes on pipelines servicing HFC's Woods Cross refinery, which had lower throughput in 2018 due to operational issues, and contractual tariff escalators.

Revenues from our intermediate pipelines were $29.6 million, a decrease of $0.1 million, on shipments averaging 140.6 mbpd compared to 144.5 mbpd for the year ended December 31, 2018. The decrease in revenue was primarily attributable to a decrease in deferred revenue realized.

Revenues from our crude pipelines were $130.7 million, an increase of $14.4 million, on shipments averaging 501.2 mbpd compared to 465.6 mbpd for the year ended December 31, 2018. The increases were mainly attributable to increased volumes on our crude pipeline systems in New Mexico and Texas and on our crude pipeline systems in Wyoming and Utah as well as contractual tariff escalators.

Revenues from terminal, tankage and loading rack fees were $160.5 million, an increase of $12.9 million compared to the year ended December 31, 2018. Refined products and crude oil terminalled in the facilities averaged 483.2 mbpd compared to 474.9 mbpd for the year ended December 31, 2018. The revenue and volume increases were mainly due to volumes at our new Orla diesel rack, higher volumes at the Spokane and Catoosa terminals and contractual tariff escalators, partially offset by lower volumes at HFC's Tulsa refinery as a result of the planned turnaround in the first quarter and flooding in the second quarter.

Revenues from refinery processing units were $79.7 million, an increase of $4.5 million on throughputs averaging 68.8 mbpd compared to 62.8 mbpd for the year ended December 31, 2018. The increase in revenue was mainly due to an adjustment in revenue recognition and contractual rate increases.

Operations Expense

Operations (exclusive of depreciation and amortization) expense for the year ended December 31, 2019, increased by $15.6 million compared to the year ended December 31, 2018. The increase for the year ended December 31, 2019 was mainly due to higher maintenance costs and employee compensation expenses.

Depreciation and Amortization

Depreciation and amortization for the year ended December 31, 2019, decreased by $1.8 million compared to the year ended December 31, 2018. The decrease was primarily due to depreciation and amortization related to our normal fluctuations in business activities.

General and Administrative

General and administrative costs for the year ended December 31, 2019, decreased by $0.8 million compared to the year ended December 31, 2018, mainly due to lower employee compensation expenses.

These increases were mainly due to higher average balances outstanding under our senior secured revolving credit facility and higher finance lease liabilities outstanding. Our aggregate weighted-average interest rates were 5.4% and 5.1% for the years ended December 31, 2019 and 2018, respectively.

State Income Tax

We recorded state income tax expense of $41,000 and $26,000 for the years ended December 31, 2019 and 2018, respectively. All state income tax expense is solely attributable to the Texas margin tax.

Results of Operations—Year Ended December 31, 2018 Compared with Year Ended December 31, 2017

Summary

Net income attributable to the partners for the year ended December 31, 2018, was $178.8 million, a $16.2 million decrease compared to the year ended December 31, 2017. The decrease in earnings was primarily due to the recognition of a $36.3 million remeasurement gain related to our acquisition of the remaining interests in SLC Pipeline and Frontier Aspen in the fourth quarter of 2017. Excluding this remeasurement gain, net income attributable to the partners increased $20.1 million primarily due to higher pipeline throughputs and revenues as well as increased earnings related to our acquisition of the remaining interests in SLC Pipeline and Frontier Aspen in the fourth quarter of 2017, which were partially offset by higher interest expense.

Revenues

Revenues for the year ended December 31, 2018, were $506.2 million, a $51.9 million increase compared to the same period of 2017. The increase was primarily attributable to our acquisition of the remaining interests in SLC Pipeline and Frontier Aspen in the fourth quarter of 2017 and the turnaround at HFC's Navajo refinery in the first quarter of 2017.

Revenues from our refined product pipelines were $137.5 million, an increase of $5.1 million, on shipments averaging 199.6 mbpd compared to 211.8 mbpd for the year ended December 31, 2017. The volume decrease was mainly due to pipelines servicing HFC's Woods Cross refinery, which had lower throughput due to operational issues at the refinery beginning in the first quarter of 2018. These decreases were partially offset by higher volumes on our product pipelines in New Mexico due to the turnaround at HFC's Navajo refinery in the first quarter of 2017. Revenue increased as a result of the higher volumes on the New Mexico product pipelines and remained relatively consistent around pipelines servicing HFC's Woods Cross refinery due to contractual minimum volume commitments and tariff escalators.

Revenues from our intermediate pipelines were $29.6 million, an increase of $0.9 million, on shipments averaging 144.5 mbpd compared to 141.6 mbpd for the year ended December 31, 2017. These increases were principally due to the turnaround at HFC's Navajo refinery in the first quarter of 2017 and increased production of base oil and lubricants at HFC's Tulsa refinery.

Revenues from our crude pipelines were $116.3 million, an increase of $42.4 million, on shipments averaging 465.6 mbpd compared to 302.9 mbpd for the year ended December 31, 2017. The increases were mainly attributable to our acquisition of the remaining interests in SLC Pipeline and Frontier Aspen in the fourth quarter of 2017, as well as increased volumes on our crude pipeline systems in New Mexico and Texas.

Revenues from terminal, tankage and loading rack fees were $147.5 million, an increase of $5.1 million compared to the year ended December 31, 2017. Refined products and crude terminalled in our facilities decreased to an average of 474.9 mbpd compared to 496.7 mbpd for the year ended December 31, 2017. Despite the decrease in volume, revenue increased primarily due to tariff escalators on minimum revenue commitments.

Revenues from refinery processing units were $75.2 million, a decrease of $1.7 million on throughputs averaging 62.8 mbpd compared to 63.6 mbpd for 2017. The reduction in revenue and volume was due to an unplanned outage on our fluid catalytic cracking unit at HFC's Woods Cross refinery in the fourth quarter of 2018.

Operations Expense

Operations (exclusive of depreciation and amortization) expense for the year ended December 31, 2018, increased by $8.8 million compared to the year ended December 31, 2017. The increase was primarily due to new operating expenses related to our acquisition of the remaining interests in SLC Pipeline and Frontier Aspen in the fourth quarter of 2017.

Depreciation and Amortization

Depreciation and amortization for the year ended December 31, 2018, increased by $19.2 million compared to the year ended December 31, 2017. The increase was primarily due to new operating expenses related to our acquisition of the remaining interests in SLC Pipeline and Frontier Aspen in the fourth quarter of 2017.

General and Administrative

General and administrative costs for the year ended December 31, 2018, decreased by $3.3 million compared to the year ended December 31, 2017, mainly due to higher legal and consulting costs incurred in the year ended December 31, 2017, associated with the IDR Restructuring Transaction.

The increase was mainly due to interest expense associated with the private placement of an additional $100 million in aggregate principal amount of our 6% Senior Notes due 2024 completed in the third quarter of 2017, higher average balances outstanding under the Credit Agreement, and market interest rate increases under the Credit Agreement. Our aggregate weighted-average interest rates were 5.1% and 4.4% for the years ended December 31, 2018 and 2017, respectively.

State Income Tax

We recorded state income tax expense of $26,000 and $249,000 for the years ended December 31, 2018 and 2017, respectively. All state income tax expense is solely attributable to the Texas margin tax.

LIQUIDITY AND CAPITAL RESOURCES

Overview

We have a $1.4 billion senior secured revolving credit facility (the “Credit Agreement”) expiring in July 2022. The Credit Agreement is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. The Credit Agreement is also available to fund letters of credit up to a $50 million sub-limit, and it contains an accordion feature giving us the ability to increase the size of the facility by up to $300 million with additional lender commitments.

During the year ended December 31, 2019, we received advances totaling $365.5 million and repaid $323.0 million, resulting in a net increase of $42.5 million under the Credit Agreement and an outstanding balance of $965.5 million at December 31, 2019. As of December 31, 2019, we had no letters of credit outstanding under the Credit Agreement, and the available capacity under the Credit Agreement was $434.5 million.

If any particular lender under the Credit Agreement could not honor its commitment, we believe the unused capacity that would be available from the remaining lenders would be sufficient to meet our borrowing needs. Additionally, we review publicly available information on the lenders in order to monitor their financial stability and assess their ongoing ability to honor their commitments under the Credit Agreement. We do not expect to experience any difficulty in the lenders’ ability to honor their respective commitments, and if it were to become necessary, we believe there would be alternative lenders or options available.

On February 4, 2020, we closed a private placement of $500 million in aggregate principal amount of 5% senior unsecured notes due in 2028 (the "5% Senior Notes"). On February 5, 2020, we redeemed the existing $500 million 6% Senior Notes at a redemption cost of $522.5 million. We will record any early extinguishment losses associated with this redemption during the first quarter of 2020. We funded the $522.5 million redemption with proceeds from the issuance of our 5% Senior Notes and borrowings under our Credit Agreement.

On January 25, 2018, we entered into a common unit purchase agreement in which certain purchasers agreed to purchase in a private placement 3,700,000 common units representing limited partnership interests, at a price of $29.73 per common unit. The private placement closed on February 6, 2018, and we received proceeds of approximately $110 million, which were used to repay indebtedness under the Credit Agreement. After this common unit issuance, HFC owns a 57% limited partner interest in us.

- 54 -

We have a continuous offering program under which we may issue and sell common units from time to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million. As of December 31, 2019, HEP has issued 2,413,153 units under this program, providing $82.3 million in gross proceeds.

On October 31, 2017, we closed on an equity restructuring transaction with HEP Logistics, a wholly-owned subsidiary of HFC and the general partner of HEP, pursuant to which the incentive distribution rights held by HEP Logistics were canceled, and HEP Logistics' 2% general partner interest in HEP was converted into a non-economic general partner interest in HEP. In consideration, we issued 37,250,000 of our common units to HEP Logistics. In addition, HEP Logistics agreed to waive $2.5 million of limited partner cash distributions for each of twelve consecutive quarters beginning with the first quarter the units issued as consideration were eligible to receive distributions. This waiver of limited partner cash distributions will expire after the cash distribution for the second quarter of 2020, which will be made during the third quarter of 2020.

On September 22, 2017, we closed a private placement of an additional $100 million in aggregate principal of our 6.0% Senior Notes for a combined aggregate principal amount outstanding of $500 million maturing in 2024. The proceeds were used to repay indebtedness outstanding under the Credit Agreement.

Under our registration statement filed with the SEC using a “shelf” registration process, we currently have the authority to raise up to $2.0 billion, less amounts issued under the $200 million continuous offering program, by offering securities, through one or more prospectus supplements that would describe, among other things, the specific amounts, prices and terms of any securities offered and how the proceeds would be used. Any proceeds from the sale of securities would be used for general business purposes, which may include, among other things, funding acquisitions of assets or businesses, working capital, capital expenditures, investments in subsidiaries, the retirement of existing debt and/or the repurchase of common units or other securities.

We believe our current cash balances, future internally generated funds and funds available under the Credit Agreement will provide sufficient resources to meet our working capital liquidity needs for the foreseeable future.

In February, May, August and November 2019, we paid regular quarterly cash distributions of $0.6675, $0.6700, $0.6725 and $0.6725, on all units in an aggregate amount of $273.2 million. In February 2020, we paid a regular cash distribution of $0.6725 on all units in an aggregate amount of $68.5 million after deducting HEP Logistics' waiver of $2.5 million of limited partner cash distributions.

Cash and cash equivalents increased by $10.2 million during the year ended December 31, 2019. The cash flows provided by operating activities of $297.1 million were more than the cash flows used for investing and financing activities of $46.3 million and $240.6 million, respectively. Working capital increased by $12.2 million to a surplus of $20.8 million at December 31, 2019 from a surplus of $8.6 million at December 31, 2018.

Cash Flows—Operating Activities

Year Ended December 31, 2019 Compared with Year Ended December 31, 2018

Cash flows provided by operating activities increased by $1.8 million from $295.2 million for the year ended December 31, 2018, to $297.1 million for the year ended December 31, 2019. This increase was mainly due to higher receipts from customers partially offset by higher payments for interest and operating expenses in the year ended December 31, 2019, as compared to the prior year.

Year Ended December 31, 2018 Compared with Year Ended December 31, 2017

Cash flows from operating activities increased by $56.7 million from $238.5 million for the year ended December 31, 2017, to $295.2 million for the year ended December 31, 2018. This increase was mainly due to higher receipts from customers partially offset by higher payments for interest and operating expenses in the year ended December 31, 2018, as compared to the prior year. The increase in customer receipts was primarily attributable to our acquisition of the remaining interests in SLC Pipeline and Frontier Aspen in the fourth quarter of 2017.

Cash Flows—Investing Activities

Year Ended December 31, 2019 Compared with Year Ended December 31, 2018

Cash flows used for investing activities decreased by $6.1 million from $52.3 million for the year ended December 31, 2018, to $46.3 million for the year ended December 31, 2019. During the years ended December 31, 2019 and 2018, we invested $30.1 million and $47.3 million in additions to properties and equipment, respectively. During the year ended December 31, 2019, we acquired a 50% interest in Cushing Connect Pipeline & Terminal LLC for $17.9 million. Additionally, we acquired businesses and assets for $5.1 million during the year ended December 31, 2018.

- 55 -

Year Ended December 31, 2018 Compared with Year Ended December 31, 2017

During the years ended December 31, 2018 and 2017, we invested $47.3 million and $44.8 million in additions to properties and equipment, respectively. During the year ended December 31, 2018, we acquired businesses and assets for $5.1 million. Additionally, we acquired the remaining 75% interest in SLC Pipeline and 50% interest in Frontier Aspen for $245.4 million in October 2017.

Cash Flows—Financing Activities

Year Ended December 31, 2019 Compared with Year Ended December 31, 2018

Cash flows used for financing activities decreased by $7.0 million from $247.6 million for the year ended December 31, 2018, to $240.6 million for the year ended December 31, 2019. During the year ended December 31, 2019, we received $365.5 million and repaid $323.0 million in advances under the Credit Agreement. Additionally, we paid $273.2 million in regular quarterly cash distributions to HEP unitholders and $9.0 million to our noncontrolling interest. During the year ended December 31, 2018, we received $337.0 million and repaid $426.0 million in advances under the Credit Agreement. We also received net proceeds of $114.8 million from the issuance of common units. Additionally, we paid $265.0 million in regular quarterly cash distributions to HEP unitholders and $7.5 million to our noncontrolling interest.

Year Ended December 31, 2018 Compared with Year Ended December 31, 2017

Cash flows used for financing activities were $247.6 million for the year ended December 31, 2018, compared to cash flows provided by financing activities of $51.9 million for the year ended December 31, 2017, a decrease of $299.5 million. During the year ended December 31, 2018, we received $337.0 million and repaid $426.0 million in advances under the Credit Agreement. We also received net proceeds of $114.8 million from issuance of common units. Additionally, we paid $265.0 million in regular quarterly cash distributions to HEP unitholders and $7.5 million to our noncontrolling interest. During the year ended December 31, 2017, we received $969.0 million and repaid $510.0 million in advances under the Credit Agreement. We also received net proceeds of $101.8 million from the issuance of our 6% Senior Notes and $52.1 million from the issuance of common units. Additionally, we paid $309.8 million for the redemption of our 6.5% Senior Notes, $234.6 million in regular quarterly cash distributions to our general and limited partners and $6.5 million to our noncontrolling interest. We also paid $9.4 million in deferred financing charges to amend the Credit Agreement.

Capital Requirements

Our pipeline and terminalling operations are capital intensive, requiring investments to maintain, expand, upgrade or enhance existing operations and to meet environmental and operational regulations. Our capital requirements have consisted of, and are expected to continue to consist of, maintenance capital expenditures and expansion capital expenditures. “Maintenance capital expenditures” represent capital expenditures to replace partially or fully depreciated assets to maintain the operating capacity of existing assets. Maintenance capital expenditures include expenditures required to maintain equipment reliability, tankage and pipeline integrity, safety and to address environmental regulations. “Expansion capital expenditures” represent capital expenditures to expand the operating capacity of existing or new assets, whether through construction or acquisition. Expansion capital expenditures include expenditures to acquire assets, to grow our business and to expand existing facilities, such as projects that increase throughput capacity on our pipelines and in our terminals. Repair and maintenance expenses associated with existing assets that are minor in nature and do not extend the useful life of existing assets are charged to operating expenses as incurred.

Each year the board of directors of HLS, our ultimate general partner, approves our annual capital budget, which specifies capital projects that our management is authorized to undertake. Additionally, at times when conditions warrant or as new opportunities arise, additional projects may be approved. The funds allocated for a particular capital project may be expended over a period in excess of a year, depending on the time required to complete the project. Therefore, our planned capital expenditures for a given year consist of expenditures approved for capital projects included in the current year’s capital budget as well as, in certain cases, expenditures approved for capital projects in capital budgets for prior years. The 2020 capital budget is comprised of approximately $8 million to $12 million for maintenance capital expenditures, $5 million to $7 million for refinery unit turnarounds and $45 to $50 million for expansion capital expenditures and our share of Cushing Connect Joint Venture investments. We expect the majority of the 2020 expansion capital budget to be invested in our share of Cushing Connect Joint Venture investments. In addition to our capital budget, we may spend funds periodically to perform capital upgrades or additions to our assets where a customer reimburses us for such costs. The upgrades or additions would generally benefit the customer over the remaining life of the related service agreements.

We expect that our currently planned sustaining and maintenance capital expenditures, as well as expenditures for acquisitions and capital development projects, will be funded with cash generated by operations, the sale of additional limited partner common units, the issuance of debt securities and advances under our Credit Agreement, or a combination thereof. With volatility and uncertainty at times in the credit and equity markets, there may be limits on our ability to issue new debt or equity financing. Additionally, due to pricing movements in the debt and equity markets, we may not be able to issue new debt and equity securities

- 56 -

at acceptable pricing. Without additional capital beyond amounts available under the Credit Agreement, our ability to obtain funds for some of these capital projects may be limited.

Under the terms of the transaction to acquire HFC’s 75% interest in UNEV, we issued to HFC a Class B unit comprising a noncontrolling equity interest in a wholly-owned subsidiary subject to redemption to the extent that HFC is entitled to a 50% interest in our share of annual UNEV earnings before interest, income taxes, depreciation, and amortization above $30 million beginning July 1, 2015, and ending in June 2032, subject to certain limitations. However, to the extent earnings thresholds are not achieved, no redemption payments are required. No redemption payments have been required to date.

Credit Agreement

We have a $1.4 billion senior secured revolving credit facility (the “Credit Agreement”) expiring in July 2022. The Credit Agreement is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. The Credit Agreement is also available to fund letters of credit up to a $50 million sub-limit, and it contains an accordion feature giving us the ability to increase the size of the facility by up to $300 million with additional lender commitments. As of December 31, 2019, we had outstanding borrowings of $965.5 million under the Credit Agreement, no letters of credit outstanding, and the available capacity was $434.5 million.

Our obligations under the Credit Agreement are collateralized by substantially all of our assets, and indebtedness under the Credit Agreement is guaranteed by our material wholly-owned subsidiaries. The Credit Agreement requires us to maintain compliance with certain financial covenants consisting of total leverage, senior secured leverage and interest coverage. It also limits or restricts our ability to engage in certain activities. If, at any time prior to the expiration of the Credit Agreement, HEP obtains two investment grade credit ratings, the Credit Agreement will become unsecured and many of the covenants, limitations, and restrictions will be eliminated.

We may prepay all loans at any time without penalty, except for tranche breakage costs. If an event of default exists under the Credit Agreement, the lenders will be able to accelerate the maturity of all loans outstanding and exercise other rights and remedies. We were in compliance with all covenants as of December 31, 2019.

Indebtedness under the Credit Agreement bears interest, at our option, at either (a) the reference rate as announced by the administrative agent plus an applicable margin (ranging from 0.50% to 1.50%) or (b) at a rate equal to LIBOR plus an applicable margin (ranging from 1.50% to 2.50%). In each case, the applicable margin is based upon the ratio of our funded debt (as defined in the Credit Agreement) to EBITDA (earnings before interest, taxes, depreciation and amortization, as defined in the Credit Agreement). The weighted-average interest rates on our Credit Agreement borrowings for both the years ending December 31, 2019 and 2018, were 4.24%. We incur a commitment fee on the unused portion of the Credit Agreement at an annual rate ranging from 0.25% to 0.50% based upon the ratio of our funded debt to EBITDA for the four most recently completed fiscal quarters.

Senior Notes

On January 4, 2017, we redeemed the $300 million aggregate principal amount of our 6.5% Senior Notes at a redemption cost of $309.8 million, at which time we recognized a $12.2 million early extinguishment loss. We funded the redemption with borrowings under our Credit Agreement.

As of December 31, 2019, we had $500 million in aggregate principal amount of 6% Senior Notes due in 2024. We used the net proceeds from our offerings of the 6% Senior Notes to repay indebtedness under our Credit Agreement.

The 6% Senior Notes were unsecured and imposed certain restrictive covenants, including limitations on our ability to incur additional indebtedness, make investments, sell assets, incur certain liens, pay distributions, enter into transactions with affiliates, and enter into mergers. We were in compliance with the restrictive covenants for the 6% Senior Notes as of December 31, 2019.

Indebtedness under the 6% Senior Notes was guaranteed by our wholly-owned subsidiaries.

On February 4, 2020, we closed the private placement of $500 million in aggregate principal amount of 5.0% senior unsecured notes due in 2028 (the "5% Senior Notes"). On February 5, 2020, redeemed the existing $500 million 6% Senior Notes at a redemption cost of $522.5 million. We will record any early extinguishment losses associated with this redemption during the first quarter of 2020. We funded the $522.5 million redemption with proceeds from the issuance of our 5% Senior Notes and borrowings under our Credit Agreement.

The 5% Senior Notes are unsecured and impose certain restrictive covenants, including limitations on our 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 5% Senior Notes are rated investment grade by either Moody’s or Standard & Poor’s and no

- 57 -

default or event of default exists, we will not be subject to many of the foregoing covenants. Additionally, we have certain redemption rights at varying premiums over face value under the 5% Senior Notes.

Indebtedness under the 5% Senior Notes is guaranteed by our wholly-owned subsidiaries.

Total	$	2,007,746	$	81,163	$	1,110,609	$	573,575	$	242,400

Long-term debt consists of outstanding principal under the Credit Agreement and the Senior Notes. Interest on the Credit Agreement is calculated using the rate in effect at December 31, 2019.

Site service fees consist of site service agreements with HFC, expiring in 2058 through 2066, for the provision of certain facility services and utility costs that relate to our assets located at HFC’s refinery facilities. We are presenting obligations for the full term of these agreements; however, the agreements can be terminated with 180 day notice if we cease to operate the applicable assets.

The pipeline finance lease amounts above reflect the exercise of the second 10-year extension, expiring in 2027, on our lease agreement for the refined products pipeline between White Lakes Junction and Kuntz Station in New Mexico.

Most of our right-of-way agreements are renewable on an annual basis, and the right-of-way agreements payments above include only obligations under the remaining non-cancelable terms of these agreements at December 31, 2019. For the foreseeable future, we intend to continue renewing these agreements and expect to incur right-of-way expenses in addition to the payments listed.

Other contractual obligations include capital lease obligations related to vehicles leases, office space leases, and other.

Impact of Inflation

Inflation in the United States has been relatively moderate in recent years and did not have a material impact on our results of operations for the years ended December 31, 2019, 2018 and 2017. PPI has increased an average of 0.6% annually over the past five calendar years, including increases of 0.8% and 3.1% in 2019 and 2018, respectively.

- 58 -

The substantial majority of our revenues are generated under long-term contracts that provide for increases or decreases in our rates and minimum revenue guarantees annually for increases or decreases in the PPI. Certain of these contracts have provisions that limit the level of annual PPI percentage rate increases or decreases. A significant and prolonged period of high inflation or a significant and prolonged period of negative inflation could adversely affect our cash flows and results of operations if costs increase at a rate greater than the fees we charge our shippers.

Our operation of pipelines, terminals, and associated facilities in connection with the transportation and storage of refined products and crude oil is subject to stringent and complex federal, state, and local laws and regulations governing the discharge of materials into the environment, or otherwise relating to the protection of the environment. As with the industry generally, compliance with existing and anticipated laws and regulations increases our overall cost of business, including our capital costs to construct, maintain, and upgrade equipment and facilities. While these laws and regulations affect our maintenance capital expenditures and net income, we believe that they do not affect our competitive position given that the operations of our competitors are similarly affected. However, these laws and regulations, and the interpretation or enforcement thereof, are subject to frequent change by regulatory authorities, and we are unable to predict the ongoing cost to us of complying with these laws and regulations or the future impact of these laws and regulations on our operations. Violation of environmental laws, regulations, and permits can result in the imposition of significant administrative, civil and criminal penalties, injunctions, and construction bans or delays. A major discharge of hydrocarbons or hazardous substances into the environment could, to the extent the event is not insured, subject us to substantial expense, including both the cost to comply with applicable laws and regulations and claims made by employees, neighboring landowners and other third parties for personal injury and property damage.

Contamination resulting from spills of refined products and crude oil is not unusual within the petroleum pipeline industry. Historic spills along our existing pipelines and terminals as a result of past operations have resulted in contamination of the environment, including soils and groundwater. Site conditions, including soils and groundwater, are being evaluated at a few of our properties where operations may have resulted in releases of hydrocarbons and other wastes, none of which we believe will have a significant effect on our operations since the remediation of such releases would be covered under environmental indemnification agreements.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers.

There are environmental remediation projects in progress that relate to certain assets acquired from HFC. Certain of these projects were underway prior to our purchase and represent liabilities retained by HFC. As of December 31, 2019, we have an accrual of $5.5 million that relates to environmental clean-up projects for which we have assumed liability or for which the indemnity provided for by HFC has expired. The remaining projects, including assessment and monitoring activities, are covered under the HFC environmental indemnification discussed above and represent liabilities of HFC.

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.

Revenue Recognition

Revenues are generally recognized as products are shipped through our pipelines and terminals, feedstocks are processed through our refinery processing units or other services are rendered. The majority of our contracts with customers meet the definition of a lease since (1) performance of the contracts is dependent on specified property, plant, or equipment and (2) the possibility is remote that one or more parties other than the customer will take more than a minor amount of the output associated with the specified property, plant, or equipment. Prior to the adoption of the new lease standard (see below), we bifurcated the consideration received between lease and service revenue. The new lease standard allows the election of a practical expedient whereby a lessor does not have to separate non-lease (service) components from lease components under certain conditions. The majority of our contracts meet these conditions, and we have made this election for those contracts. Under this practical expedient, we treat the combined components as a single performance obligation in accordance with Accounting Standards Codification (“ASC”) 606, which largely codified ASU 2014-09, if the non-lease (service) component is the dominant component. If the lease component

- 59 -

is the dominant component, we treat the combined components as a lease in accordance with ASC 842, which largely codified ASU 2016-02.

Several of our contracts include incentive or reduced tariffs once a certain quarterly volume is met. Revenue from the variable element of these transactions is recognized based on the actual volumes shipped as it relates specifically to rendering the services during the applicable quarter.

The majority of our long-term transportation contracts specify minimum volume requirements, whereby, we bill a customer for a minimum level of shipments in the event a customer ships below their contractual requirements. If there are no future performance obligations, we will recognize these deficiency payments in revenue.

In certain of these throughput agreements, a customer may later utilize such shortfall billings as credit towards future volume shipments in excess of its minimum levels within its respective contractual shortfall make-up period. Such amounts represent an obligation to perform future services, which may be initially deferred and later recognized as revenue based on estimated future shipping levels, including the likelihood of a customer’s ability to utilize such amounts prior to the end of the contractual shortfall make-up period. We recognize these deficiency payments in revenue when we do not expect we will be required to satisfy these performance obligations in the future based on the pattern of rights exercised by the customer.

Prior to the adoption of ASC 606 on January 1, 2018, billings to customers for their obligations under their quarterly minimum revenue commitments were recorded as deferred revenue liabilities if the customer had the right to receive future services for these billings. The revenue was recognized at the earlier of:

• the customer receiving the future services provided by these billings,

• the period in which the customer was contractually allowed to receive the services expired, or

• our determination that we would not be required to provide services within the allowed period.

We determined that we would not be required to provide services within the allowed period when, based on current and projected shipping levels, our pipeline systems would not have the necessary capacity to enable a customer to exceed its minimum volume levels to such a degree as to utilize the shortfall credit within its respective contractual shortfall make-up period.

Goodwill and Long-Lived Assets

Goodwill represents the excess of our cost of an acquired business over the fair value of the assets acquired, less liabilities assumed. Goodwill is not amortized. We test goodwill at the reporting unit level for impairment annually and between annual tests if events or changes in circumstances indicate the carrying amount may exceed fair value. Our goodwill impairment testing first entails a comparison of our reporting unit fair values relative to their respective carrying values, including goodwill. If carrying value exceeds fair value for a reporting unit, we measure goodwill impairment as the excess of the carrying amount of reporting unit goodwill over the implied fair value of that goodwill based on estimates of the fair value of all assets and liabilities in the reporting unit.

In 2019, we assessed qualitative factors such as macroeconomic conditions, industry considerations, cost factors, and reporting unit financial performance and determined it was not more likely than not that the fair value of our reporting units were less than the respective carrying value. Therefore, in accordance with GAAP, further testing was not required. In 2018, we used the present value of the expected future net cash flows and market multiple analyses to determine the estimated fair values of the reporting units. The impairment test requires the use of projections, estimates and assumptions as to the future performance of our operations. Actual results could differ from projections resulting in revisions to our assumptions, and if required, could result in the recognition of an impairment loss.

We evaluate long-lived assets, including finite-lived intangible 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.

There have been no impairments to goodwill or our long-lived assets through December 31, 2019.

Accounting Pronouncement Adopted During the Periods Presented

Goodwill Impairment Testing

In January 2017, Accounting Standard Update (“ASU”) 2017-04, “Simplifying the Test for Goodwill Impairment,” was issued amending the testing for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under this standard, goodwill impairment is measured as the excess of the carrying amount of the reporting unit over the related fair value. We adopted this standard effective in the second quarter of 2019, and the adoption of this standard had no effect on our financial condition, results of operations or cash flows.

Leases

In February 2016, ASU 2016-02, “Leases” (“ASC 842”) was issued requiring leases to be measured and recognized as a lease liability, with a corresponding right-of-use asset on the balance sheet. We adopted this standard effective January 1, 2019, and we elected to adopt using the modified retrospective transition method, whereby comparative prior period financial information will not be restated and will continue to be reported under the lease accounting standard in effect during those periods. We also elected practical expedients provided by the new standard, including the package of practical expedients and the short-term lease recognition practical expedient, which allows an entity to not recognize on the balance sheet leases with a term of 12 months or less. Upon adoption of this standard, we recognized $78.4 million of lease liabilities and corresponding right-of-use assets on our consolidated balance sheet. Adoption of the standard did not have a material impact on our results of operations or cash flows. See Notes 4 and 5 of Notes to the Consolidated Financial Statements for additional information on our lease policies.

Revenue Recognition

In May 2014, an accounting standard update was issued requiring revenue to be recognized when promised goods or services are transferred to customers in an amount that reflects the expected consideration for these goods or services. This standard had an effective date of January 1, 2018, and we accounted for the new guidance using the modified retrospective implementation method, whereby a cumulative effect adjustment was recorded to retained earnings as of the date of initial application. In preparing for adoption, we evaluated the terms, conditions and performance obligations under our existing contracts with customers. Furthermore, we implemented policies to comply with this new standard. See above and Note 4 to the consolidated financial statements for additional information on our revenue recognition policies.

Business Combinations

In December 2014, an accounting standard update was issued to provide new guidance on the definition of a business in relation to accounting for identifiable intangible assets in business combinations. This standard had an effective date of January 1, 2018, and had no effect on our financial condition, results of operations or cash flows.

Financial Assets and Liabilities

In January 2016, an accounting standard update was issued requiring changes in the accounting and disclosures for financial instruments. This standard was effective beginning with our 2018 reporting year and had no effect on our financial condition, results of operations or cash flows.

Accounting Pronouncements Not Yet Adopted

Credit Losses Measurement

In June 2016, ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” was issued requiring measurement of all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This standard is effective January 1, 2020, and our preliminary review of historic and expected credit losses indicates the amount of expected credit losses upon adoption would not have a material impact on our financial condition, results of operations or cash flows.

RISK MANAGEMENT

The two interest rate swaps that hedged our exposure to the cash flow risk caused by the effects of LIBOR changes on $150 million of Credit Agreement matured on July 31, 2017. The swaps had effectively converted $150 million of our LIBOR based debt to fixed rate debt.

The market risk inherent in our debt positions is the potential change arising from increases or decreases in interest rates as discussed below.

- 61 -

At December 31, 2019, we had an outstanding principal balance of $500 million on our 6% Senior Notes. A change in interest rates generally would affect the fair value of the 6% Senior Notes, but not our earnings or cash flows. At December 31, 2019, the fair value of our 6% Senior Notes was $522 million. We estimate a hypothetical 10% change in the yield-to-maturity applicable to the 6% Senior Notes at December 31, 2019, would result in a change of approximately $10 million in the fair value of the underlying 6% Senior Notes.

For the variable rate Credit Agreement, changes in interest rates would affect cash flows, but not the fair value. At December 31, 2019, borrowings outstanding under the Credit Agreement were $965.5 million. A hypothetical 10% change in interest rates applicable to the Credit Agreement would not materially affect our cash flows.

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

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

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Market risk is the risk of loss arising from adverse changes in market rates and prices. See “Risk Management” under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for a discussion of market risk exposures that we have with respect to our long-term debt. We utilize derivative instruments to hedge our interest rate exposure, as discussed under “Risk Management.”

Since we do not own products shipped on our pipelines or terminalled at our terminal facilities, we do not have direct market risks associated with commodity prices.

Item 8. Financial Statements and Supplementary Data

MANAGEMENT’S REPORT ON ITS ASSESSMENT OF THE PARTNERSHIP’S INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of Holly Energy Partners, L.P. (the “Partnership”) 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 Partnership’s internal control over financial reporting as of December 31, 2019, using the criteria for effective control over financial reporting established in “Internal Control – Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this assessment, management concluded that, as of December 31, 2019, the Partnership maintained effective internal control over financial reporting.

The Partnership’s independent registered public accounting firm has issued an attestation report on the effectiveness of the Partnership’s internal control over financial reporting as of December 31, 2019. That report appears on page 64.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Unitholders of Holly Energy Partners, L.P. and the Board of Directors of Holly Logistic Services, L.L.C.

Opinion on Internal Control over Financial Reporting

We have audited Holly Energy Partners, L.P.’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Holly Energy Partners, L.P. (the Partnership) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Partnership as of December 31, 2019 and 2018, the related consolidated statements of income, comprehensive income, cash flows, and equity for each of the three years in the period ended December 31, 2019, and the related notes of the Partnership and our report dated February 20, 2020 expressed an unqualified opinion thereon.

Basis for Opinion

The Partnership’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 Partnership’s Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Partnership’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

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

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To Unitholders of Holly Energy Partners, L.P. and the Board of Directors of Holly Logistic Services, L.L.C.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Holly Energy Partners, L.P. (the Partnership) as of December 31, 2019 and 2018, the related consolidated statements of income, comprehensive income, cash flows, and equity for each of the three years in the period ended December 31, 2019, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Partnership at December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Partnership's internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 20, 2020 expressed an unqualified opinion thereon.

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

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

Basis for Opinion

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

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

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments.

	Revenue Recognition
Description of the Matter	For the year ended December 31, 2019, the Partnership’s total revenues were $532.8 million. As discussed in Note 1 and Note 4 of the financial statements, revenues are generally recognized as products are shipped through pipelines and terminals, feedstocks are processed through the refinery processing units or other services are rendered. The majority of the Partnership’s long-term throughput agreements with customers specify minimum volume requirements. In the event a customer does not fulfill minimum volume requirements during a contractual period, the Partnership can bill the customer for the minimum level. In certain contracts, a customer may later utilize these shortfall billings as credit towards future throughput volumes in excess of minimum levels within a respective contractual shortfall make-up period. Shortfall billing amounts represent an obligation to provide future capacity and may be initially deferred and later recognized as revenue. Recognition is based on estimated future throughput volumes, including the likelihood of a customer’s ability to utilize such amounts prior to the end of the contractual shortfall make-up period or when the Partnership does not expect to be required to satisfy these performance obligations in the future based on the pattern of rights exercised by the customer.
	Auditing the measurement of the Partnership’s revenue was complex and judgmental due to various contractual provisions used in customer agreements and measurement uncertainty associated with management’s estimates of deferred revenue related to the future utilization of shortfall billings.

How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Partnership’s revenue recognition process. This included testing relevant controls over the review of the accounting analysis upon execution of a customer contract, as well as controls over management’s estimates affecting deferred revenue associated with shortfall billings. Our audit procedures over the Partnership’s revenue included, among others, inspecting a sample of new and existing contracts to understand the contractual terms and assessing the completeness of deferred revenue, testing a sample of revenue transactions to evaluate whether revenue was recorded in accordance with the contract terms, performing recalculations of the deferred revenue amounts related to shortfall billings, and testing management’s estimation of deferred revenue based on historical pattern of rights exercised by the customer and expected future usage.
	Sales-Type Lease Accounting
Description of the Matter	As disclosed in Note 5 of the financial statements, one of the Partnership’s throughput agreements with HFC was renewed during 2019 and certain components of the agreement met the criteria for sales-type lease accounting since the underlying assets are not expected to have an alternative use other than to HFC. Under sales-type lease accounting, the lessor recognizes a net investment in the lease and derecognizes the underlying assets with the difference recorded as gain or loss. At the lease commencement date in 2019, the Partnership recorded net investment in leases of $122.8 million and recognized a gain on sales-type leases of $35.2 million. Auditing management’s accounting for the sales-type leases was complex and highly judgmental due to the estimation uncertainty in determining the fair values of the underlying leased assets at the renewal date. The fair values of the underlying leased assets are factored into the Partnership’s determination of the net investment in the leases. The fair value estimates were sensitive to significant assumptions and inputs used based on a replacement cost valuation method, such as estimates of the replacement cost of pipelines, the cost of right of ways, and the effective age of pipelines. These assumptions have a significant effect on the fair value estimates.
How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Partnership's evaluation of the lease classification and related accounting for sales-type leases. For example, we tested controls over management's review of the significant inputs and assumptions used in estimating the fair value of the underlying leased assets. To test the Partnership’s accounting for sales-type leases including the estimated fair value of the underlying leased assets, we performed audit procedures with the support of a valuation specialist that included, among others, assessing methodologies and testing the significant assumptions discussed above and the underlying data used by the Partnership in its analysis. We compared the significant replacement cost assumptions used by management to recent cost proposals for pipeline projects and related right of ways. We also inspected supporting documentation, such as evidence related to maintenance records, to assess the effective age of the pipeline.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2019

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

Holly Energy Partners, L.P. (“HEP”) together with its consolidated subsidiaries, is a publicly held master limited partnership. As of December 31, 2019, HollyFrontier Corporation (“HFC”) and its subsidiaries own a 57% limited partner interest and the non-economic general partner interest in HEP. We commenced operations on July 13, 2004, upon the completion of our initial public offering. In these consolidated financial statements, the words “we,” “our,” “ours” and “us” refer to HEP unless the context otherwise indicates.

On October 31, 2017, we closed on an equity restructuring transaction with HEP Logistics Holdings, L.P. (“HEP Logistics”), a wholly-owned subsidiary of HFC and the general partner of HEP, pursuant to which the incentive distribution rights ("IDRs") held by HEP Logistics were canceled, and HEP Logistics' 2% general partner interest in HEP was converted into a non-economic general partner interest in HEP. In consideration, we issued 37,250,000 of our common units to HEP Logistics. In addition, HEP Logistics agreed to waive $2.5 million of limited partner cash distributions for each of twelve consecutive quarters beginning with the first quarter the units issued as consideration were eligible to receive distributions. This waiver of limited partner cash distributions will expire after the cash distribution for the second quarter of 2020, which will be made during the third quarter of 2020. As a result of this transaction, no distributions were made on the general partner interest after October 31, 2017.

On January 25, 2018, we entered into a common unit purchase agreement in which certain purchasers agreed to purchase in a private placement 3,700,000 common units representing limited partner interests, at a price of $29.73 per common unit. The private placement closed on February 6, 2018, and we received proceeds of approximately $110 million, which were used to repay indebtedness under our revolving credit facility.

We own and operate petroleum product and crude oil pipelines, terminal, tankage and loading rack facilities and refinery processing units that support the refining and marketing operations of HFC and other refineries in the Mid-Continent, Southwest and Northwest regions of the United States and Delek US Holdings, Inc.’s (“Delek”) refinery in Big Spring, Texas. Additionally, we own a 75% interest in the UNEV Pipeline, LLC (“UNEV”), a 50% interest in Osage Pipe Line Company, LLC (“Osage”), a 50% interest in Cheyenne Pipeline LLC, and a 50% interest in Cushing Connect Pipeline & Terminal LLC.

We operate in two reportable segments, a Pipelines and Terminals segment and a Refinery Processing Unit segment. Disclosures around these segments are discussed in Note 16.

Our Pipelines and Terminals segment consists of:

• 26 main pipeline segments

• Crude gathering networks in Texas and New Mexico

• 10 refined product terminals

• 1 crude terminal

• 31,800 track feet of rail storage located at two facilities

• 7 locations with truck and/or rail racks

• Tankage at all six of HFC's refining facility locations

Our Refinery Processing Unit segment consists of five refinery processing units at two of HFC's refining facility locations.

We generate revenues by charging tariffs for transporting petroleum products and crude oil through our pipelines, by charging fees for terminalling and storing refined products and other hydrocarbons, providing other services at our storage tanks and terminals and by charging fees for processing hydrocarbon feedstocks through our refinery processing units. We do not take ownership of products that we transport, terminal, store or process, and therefore, we are not exposed directly to changes in commodity prices.

Principles of Consolidation and Common Control Transactions

The consolidated financial statements include our accounts, our Predecessor's (defined below) and those of subsidiaries and joint ventures that we control. All significant intercompany transactions and balances have been eliminated. Certain prior period balances have been reclassified for consistency with current year presentation.

Most of our acquisitions from HFC occurred while we were a consolidated variable interest entity of HFC. Therefore, as an entity under common control with HFC, we recorded these acquisitions on our balance sheets at HFC's historical basis instead of our purchase price or fair value. U.S. generally accepted accounting principles ("GAAP") require transfers of a business between entities under common control to be accounted for as though the transfer occurred as of the beginning of the period of transfer,

- 74 -

and prior period financial statements and financial information are retrospectively adjusted to include the historical results and assets of the acquisitions from HFC for all periods presented prior to the effective dates of each acquisition. We refer to the historical results of the acquisitions prior to their respective acquisition dates as those of our "Predecessor." Many of these transactions are cash purchases and do not involve the issuance of equity; however, GAAP requires the retrospective adjustment of financial statements. Therefore, in such transactions, the prior year balance sheet includes as equity the amount of cost incurred by HFC to that date.

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 and Cash Equivalents

For purposes of the statements of cash flows, we consider all highly liquid investments with maturities of three months or less at the time of purchase to be cash equivalents. The carrying amounts reported on the balance sheets approximate fair value due to the short-term maturity of these instruments.

Accounts Receivable

The majority of the accounts receivable are due from affiliates of HFC or independent 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, may be required. Credit losses are charged to income when accounts are deemed uncollectible and historically have been minimal.

Properties and Equipment

Properties and equipment are stated at cost. Properties and equipment acquired from HFC while under common control of HFC are stated at HFC's historical basis. Depreciation is provided by the straight-line method over the estimated useful lives of the assets, primarily 15 to 25 years for terminal facilities and tankage, 25 to 30 years for pipelines, 25 years for refinery processing units and 3 to 10 years for corporate and other assets. We depreciate assets acquired under capital leases over the lesser of the lease term or the economic life of the assets. Maintenance, repairs and minor replacements are expensed as incurred. Costs of replacements constituting improvements are capitalized.

Intangible Assets

Intangible assets include transportation agreements and acquired customer relationship intangible assets. Intangible assets are stated at acquisition date fair value and are being amortized over their useful lives using the straight-line method.

Goodwill and Long-Lived Assets

Goodwill represents the excess of our cost of an acquired business over the fair value of the assets acquired, less liabilities assumed. Goodwill is not amortized. We test goodwill at the reporting unit level for impairment annually and between annual tests if events or changes in circumstances indicate the carrying amount may exceed fair value. Our goodwill impairment testing first entails a comparison of our reporting unit fair values relative to their respective carrying values, including goodwill. If carrying value exceeds fair value for a reporting unit, we measure goodwill impairment as the excess of the carrying amount of reporting unit goodwill over the implied fair value of that goodwill based on estimates of the fair value of all assets and liabilities in the reporting unit.

In 2019, we assessed qualitative factors such as macroeconomic conditions, industry considerations, cost factors, and reporting unit financial performance and determined it was not more likely than not that the fair value of our reporting units were less than the respective carrying value. Therefore, in accordance with GAAP, further testing was not required. In 2018, we used the present value of the expected future net cash flows and market multiple analyses to determine the estimated fair values of the reporting units. The impairment test requires the use of projections, estimates and assumptions as to the future performance of our operations. Actual results could differ from projections resulting in revisions to our assumptions, and if required, could result in the recognition of an impairment loss.

We evaluate long-lived assets, including finite intangible 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.

- 75 -

There have been no impairments to goodwill or our long-lived assets through December 31, 2019.

Investment in Equity Method Investments

We account for our interests in noncontrolling joint venture interests using the equity method of accounting, whereby we record our pro-rata share of earnings of these companies, and contributions to and distributions from the joint ventures as adjustments to our investment balances. The difference between the cost of an investment and our proportionate share of the underlying equity in net assets recorded on the investee's books is allocated to the various assets and liabilities of the equity method investment.

The following table summarizes our recorded investments compared to our share of underlying equity for each investee. We are amortizing the differences as adjustments to our pro-rata share of earnings over the useful lives of the underlying assets of these joint ventures.

	Balance at December 31, 2019

Cheyenne Pipeline LLC	29,358		43,357		(13,999		)
Total	$	39,322	$	83,840	$	(44,518	)

Asset Retirement Obligations

We record legal obligations associated with the retirement of certain of our long-lived assets that result from the acquisition, construction, development and/or the normal operation of our long-lived assets. The fair value of the estimated cost to retire a tangible long-lived asset is recorded in the period in which the liability is incurred and when a reasonable estimate of the fair value of the liability can be made. For our pipeline assets, the right-of-way agreements typically do not require the dismantling, removal and reclamation of the right-of-way upon cessation of the pipeline service. Additionally, management is unable to predict when, or if, our pipelines and related facilities would become obsolete and require decommissioning. Accordingly, we have recorded no liability or corresponding asset related to an asset retirement obligation for the majority of our pipelines as both the amounts and timing of such potential future costs are indeterminable. For our remaining assets, at December 31, 2019 and 2018, we have asset retirement obligations of $7.7 million and $8.9 million, respectively, that are recorded under “Other long-term liabilities” in our consolidated balance sheets.

Class B Unit

Under the terms of the transaction to acquire HFC's 75% interest in UNEV, we issued HFC a Class B unit comprising a noncontrolling equity interest in a wholly-owned subsidiary subject to redemption to the extent that HFC is entitled to a 50% interest in our share of annual UNEV earnings before interest, income taxes, depreciation, and amortization above $30 million beginning July 1, 2016, and ending in June 2032, subject to certain limitations. Such contingent redemption payments are limited to the unredeemed value of the Class B Unit. However, to the extent earnings thresholds are not achieved, no redemption payments are required. No redemption payments have been required to date.

- 76 -

Contemporaneously with this transaction, HFC (our general partner) agreed to forego its right to incentive distributions of up to $1.25 million per quarter over twelve consecutive quarterly periods following the closing of the transaction and up to an additional four quarters if HFC's Woods Cross refinery expansion did not attain certain thresholds. HEP Logistics' waiver of its right to incentive distributions of $1.25 million per quarter ended with the distribution paid in the third quarter of 2016.

Pursuant to the terms of the transaction agreements, the Class B unit increases by the amount of each foregone incentive distribution and by a 7% factor compounded annually on the outstanding unredeemed balance through its expiration date. At our option, we may redeem, in whole or in part, the Class B unit at the current unredeemed value based on the calculation described. The Class B unit had a carrying value of 49.4 million at December 31, 2019, and 46.2 million at December 31, 2018.

Revenue Recognition

Revenues are generally recognized as products are shipped through our pipelines and terminals, feedstocks are processed through our refinery processing units or other services are rendered. The majority of our contracts with customers meet the definition of a lease since (1) performance of the contracts is dependent on specified property, plant, or equipment and (2) it is remote that one or more parties other than the customer will take more than a minor amount of the output associated with the specified property, plant, or equipment. Prior to the adoption of the new lease standard (see below), we bifurcated the consideration received between lease and service revenue. The new lease standard allows the election of a practical expedient whereby a lessor does not have to separate non-lease (service) components from lease components under certain conditions. The majority of our contracts meet these conditions, and we have made this election for those contracts. Under this practical expedient, we treat the combined components as a single performance obligation in accordance with Accounting Standards Codification (“ASC”) 606, which largely codified ASU 2014-09, if the non-lease (service) component is the dominant component. If the lease component is the dominant component, we treat the combined components as a lease in accordance with ASC 842, which largely codified ASU 2016-02.

See Note 4 for further discussion of revenue recognition.

Prior to the adoption of ASC 606 on January 1, 2018, billings to customers for their obligations under their quarterly minimum revenue commitments were recorded as deferred revenue liabilities if the customer had the right to receive future services for these billings. The revenue was recognized at the earlier of:

• the customer receiving the future services provided by these billings,

• the period in which the customer was contractually allowed to receive the services expired, or

• our determination that we would not be required to provide services within the allowed period.

We determined that we would not be required to provide services within the allowed period when, based on current and projected shipping levels, our pipeline systems would not have the necessary capacity to enable a customer to exceed its minimum volume levels to such a degree as to utilize the shortfall credit within its respective contractual shortfall make-up period.

We have additional revenues under an operating lease to a third party of an interest in the capacity of one of our pipelines.

We have other cost reimbursement provisions in our throughput / storage agreements providing that customers (including HFC) reimburse us for certain costs. Such reimbursements are recorded as revenue or deferred revenue depending on the nature of the cost. Deferred revenue is recognized over the remaining contractual term of the related throughput agreement.

Taxes billed and collected from our pipeline and terminal customers are recorded on a net basis with no effect on net income.

Environmental Costs

Environmental costs are expensed 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, time frame and extent of required remedial and clean-up activities and are subject to periodic adjustments based on currently available information.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC occurring or existing prior to the date of such transfers. We have an

- 77 -

environmental agreement with Delek with respect to pre-closing environmental costs and liabilities relating to the pipelines and terminals acquired from Delek in 2005, under which Delek will indemnify us subject to certain monetary and time limitations. Environmental costs recoverable through insurance, indemnification agreements or other sources are included in other assets to the extent such recoveries are considered probable.

Income Tax

We are subject to the Texas margin tax that is based on our Texas sourced taxable margin. The tax is calculated by applying a tax rate to a base that considers both revenues and expenses and therefore has the characteristics of an income tax.

We are organized as a pass-through entity for federal income tax purposes. As a result, our partners are responsible for federal income taxes based on their respective share of taxable income.

Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under the partnership agreement.

Net Income per Limited Partners' Unit

Net income per unit applicable to the limited partners was computed using the two-class method since we had more than one class of participating securities during the period from January 1, 2017 through October 31, 2017.  The classes of participating securities during this period included common units, general partner units and IDRs. Due to the equity restructuring transaction described above, as of December 31, 2017, we had one class of security outstanding, common units. To the extent net income attributable to the partners exceeds or is less than cash distributions, this difference is allocated to the partners based on their weighted-average ownership percentage during the period, after consideration of any priority allocations of earnings. Other participating securities and dilutive securities are not significant.

Accounting Pronouncement Adopted During the Periods Presented

Goodwill Impairment Testing

In January 2017, Accounting Standard Update (“ASU”) 2017-04, “Simplifying the Test for Goodwill Impairment,” was issued amending the testing for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under this standard, goodwill impairment is measured as the excess of the carrying amount of the reporting unit over the related fair value. We adopted this standard effective in the second quarter of 2019, and the adoption of this standard had no effect on our financial condition, results of operations or cash flows.

Leases

In February 2016, ASU No. 2016-02, “Leases” (“ASC 842”) was issued requiring leases to be measured and recognized as a lease liability, with a corresponding right-of-use asset on the balance sheet. We adopted this standard effective January 1, 2019, and we elected to adopt using the modified retrospective transition method, whereby comparative prior period financial information will not be restated and will continue to be reported under the lease accounting standard in effect during those periods. We also elected practical expedients provided by the new standard, including the package of practical expedients and the short-term lease recognition practical expedient, which allows an entity to not recognize on the balance sheet leases with a term of 12 months or less. Upon adoption of this standard, we recognized $78.4 million of lease liabilities and corresponding right-of-use assets on our consolidated balance sheet. See Notes 4 and 5 of Notes to the Consolidated Financial Statements for additional information on our lease policies.

Revenue Recognition

In May 2014, an accounting standard update was issued requiring revenue to be recognized when promised goods or services are transferred to customers in an amount that reflects the expected consideration for these goods or services. This standard had an effective date of January 1, 2018, and we accounted for the new guidance using the modified retrospective implementation method, whereby a cumulative effect adjustment was recorded to retained earnings as of the date of initial application. In preparing for adoption, we evaluated the terms, conditions and performance obligations under our existing contracts with customers. Furthermore, we implemented policies to comply with this new standard. See above and Note 4 for additional information on our revenue recognition policies.

- 78 -

Business Combinations

In December 2014, an accounting standard update was issued to provide new guidance on the definition of a business in relation to accounting for identifiable intangible assets in business combinations. This standard had an effective date of January 1, 2018, and had no effect on our financial condition, results of operations or cash flows.

Financial Assets and Liabilities

In January 2016, an accounting standard update was issued requiring changes in the accounting and disclosures for financial instruments. This standard was effective beginning with our 2018 reporting year and had no effect on our financial condition, results of operations or cash flows.

Accounting Pronouncements Not Yet Adopted

Credit Losses Measurement

In June 2016, ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” was issued requiring measurement of all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This standard is effective January 1, 2020, and our preliminary review of historic and expected credit losses indicates the amount of expected credit losses upon adoption would not have a material impact on our financial condition, results of operations or cash flows.

Note 2: Acquisitions

SLC Pipeline and Frontier Aspen

On October 31, 2017, we acquired the remaining 75% interest in SLC Pipeline LLC ("SLC Pipeline") and the remaining 50% interest in Frontier Aspen LLC ("Frontier Aspen") from subsidiaries of Plains All American Pipeline, L.P. (“Plains”), for cash consideration of $250 million. Prior to this acquisition, we held noncontrolling interests of 25% of SLC Pipeline and 50% of Frontier Aspen. As a result of the acquisitions, SLC Pipeline and Frontier Aspen are wholly-owned subsidiaries of HEP.

These acquisitions were accounted for as a business combination achieved in stages. Our preexisting equity method investments in SLC Pipeline and Frontier Aspen were remeasured at an acquisition date fair value of $112 million since we now have a controlling interest, and we recognized a gain on the remeasurement in the fourth quarter of 2017 of $36.3 million. The fair value of our preexisting equity method investments in SLC Pipeline and Frontier Aspen was estimated using Level 3 Inputs under the income method for these entities, adjusted for lack of control and marketability.

The total consideration of $363.8 million, consisting of cash consideration of $250 million, working capital adjustments of $1.8 million and the fair value of our preexisting equity method investments in SLC Pipeline and Frontier Aspen of $112 million, was allocated to the acquisition date fair value of assets and liabilities acquired as of the October 31, 2017 acquisition date, with the excess purchase price recorded as goodwill.

The following summarizes the final estimated value of assets and liabilities acquired:

	(in thousands)
Cash and cash equivalents	$	4,609
Accounts receivable	5,164
Prepaid and other current assets	8
Properties and equipment	275,061
Intangible assets	70,182
Goodwill	13,845
Accounts payable	(3,598		)
Accrued property taxes	(1,438		)
Net assets acquired	$	363,833

Our consolidated financial and operating results reflect the SLC Pipeline and Frontier Aspen operations beginning November 1, 2017. Our results of operations for the year ended December 31, 2017 included revenues of $7.9 million and net income of $4.1 million, excluding the $36.3 million remeasurement gain as of the acquisition date discussed above, for the period from November 1, 2017 through December 31, 2017.

SLC Pipeline is the owner of a 95-mile crude pipeline that transports crude oil into the Salt Lake City area from the Utah terminal of the Frontier Pipeline (defined below) and from Wahsatch Station. Frontier Aspen is the owner of a 289-mile crude pipeline from Casper, Wyoming to Frontier Station, Utah (the "Frontier Pipeline") that supplies Canadian and Rocky Mountain crudes to Salt Lake City area refiners through a connection to the SLC Pipeline.

The following unaudited pro forma financial information combines the historical operations of HEP, SLC Pipeline and Frontier Aspen as if the acquisition had occurred on January 1, 2017:

	Years Ended December 31,
	2017
Revenues	$	489,382
Net income attributable to the partners	$	161,900

The unaudited pro forma net income attributable to the partners reflects the following adjustments:

(1) To retrospectively reflect depreciation and amortization of intangible assets based on the preliminary fair value of the assets as if that fair value had been reflected January 1, 2017;

(2) To eliminate HEP's equity income previously recorded on its equity method investments in SLC Pipeline and Frontier Aspen; and

(3) To eliminate the remeasurement gain on preexisting equity interests in SLC Pipeline and Frontier Aspen.

Note 3: Investment in Joint Venture

On October 2, 2019, HEP Cushing LLC (“HEP Cushing”), a wholly-owned subsidiary of HEP, and Plains Marketing, L.P., a wholly-owned subsidiary of Plains, formed a 50/50 joint venture, Cushing Connect Pipeline & Terminal LLC (the “Cushing Connect Joint Venture”), for (i) the development and construction of a new 160,000 barrel per day common carrier crude oil pipeline (the “Cushing Connect Pipeline”) that will connect the Cushing, Oklahoma crude oil hub to the Tulsa, Oklahoma refining complex owned by a subsidiary of HFC and (ii) the ownership and operation of 1.5 million barrels of crude oil storage in Cushing, Oklahoma (the “Cushing Connect JV Terminal”). The Cushing Connect JV Terminal is expected to be placed in service during the second quarter of 2020, and the Cushing Connect Pipeline is expected to be placed in service during the first quarter of 2021. Long-term commercial agreements have been entered into to support the Cushing Connect Joint Venture assets.

The Cushing Connect Joint Venture has contracted with an affiliate of HEP to manage the construction and operation of the Cushing Connect Pipeline and with an affiliate of Plains to manage the operation of the Cushing Connect JV Terminal. The total Cushing Connect Joint Venture investment will generally be shared equally among HEP and Plains, and HEP estimates its share of the cost of the Cushing Connect JV Terminal contributed by Plains and Cushing Connect Pipeline construction costs are approximately $65 million. However, any Cushing Connect Pipeline construction costs exceeding 10% of the budget are borne solely by us.

The Cushing Connect Joint Venture legal entities are variable interest entities ("VIEs") as defined under GAAP. A VIE is a legal entity if it has any one of the following characteristics: (i) the entity does not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support; (ii) the at risk equity holders, as a group, lack the characteristics of a controlling financial interest; or (iii) the entity is structured with non-substantive voting rights. The Cushing Connect Joint Venture legal entities do not have sufficient equity at risk to finance their activities without additional financial support. Since HEP is constructing and will operate the Cushing Connect Pipeline, HEP has more ability to direct the activities that most significantly impact the financial performance of the Cushing Connect Joint Venture and Cushing Connect Pipeline legal entities (collectively, the "Cushing Connect VIEs"). Therefore, HEP consolidates the Cushing Connect VIEs.

We do not have the ability to direct the activities that most significantly impact the Cushing Connect JV Terminal legal entity, and therefore, we account for our interest in the Cushing Connect JV Terminal legal entity using the equity method of accounting.

- 80 -

With the exception of the assets of HEP Cushing, creditors of the Cushing Connect Joint Venture legal entities have no recourse to our assets. Any recourse to HEP Cushing would be limited to the extent of HEP Cushing's assets, which other than its investment in Cushing Connect Joint Venture, are not significant. Furthermore, our creditors have no recourse to the assets of the Cushing Connect Joint Venture legal entities.

Note 4: Revenues

We adopted the new revenue recognition standard (see Note 1) using the modified retrospective method, whereby the cumulative effect of applying the new standard was recorded as an adjustment to the opening balance of partners’ equity as well as the carrying amounts of assets and liabilities as of January 1, 2018, which had no impact on our cash flows. The following table reflects the cumulative effect of adoption as of January 1, 2018:

	Prior to Adoption		Increase (Decrease)			As Adjusted
	(In thousands)
Deferred revenue	$	9,598	$	(1,320	)	$	8,278
Partners’ equity: Common unitholders	$	393,959	$	1,320		$	395,279

Several of our contracts include incentive or reduced tariffs once a certain quarterly volume is met. Revenue from the variable element of these transactions is recognized based on the actual volumes shipped as it relates specifically to rendering the services during the applicable quarter.

The majority of our long-term transportation contracts specify minimum volume requirements, whereby, we bill a customer for a minimum level of shipments in the event a customer ships below their contractual requirements. If there are no future performance obligations, we will recognize these deficiency payments in revenue.

In certain of these throughput agreements, a customer may later utilize such shortfall billings as credit towards future volume shipments in excess of its minimum levels within its respective contractual shortfall make-up period. Such amounts represent an obligation to perform future services, which may be initially deferred and later recognized as revenue based on estimated future shipping levels, including the likelihood of a customer’s ability to utilize such amounts prior to the end of the contractual shortfall make-up period. We recognize these deficiency payments in revenue when we do not expect we will be required to satisfy these performance obligations in the future based on the pattern of rights exercised by the customer. During the twelve months ended December 31, 2019, 2018 and 2017, we recognized $16.0 million, $17.6 million and $11.9 million, respectively, of these deficiency payments in revenue, of which $0.6 million, $3.3 million and $5.6 million, respectively, related to deficiency payments billed in prior periods. As of December 31, 2019, deferred revenue reflected in our consolidated balance sheet related to shortfalls billed was $0.7 million.

A contract liability exists when an entity is obligated to perform future services to a customer for which the entity has received consideration. Since HEP may be required to perform future services for these deficiency payments received, the deferred revenues on our balance sheet as of December 31, 2019 were considered contract liabilities. A contract asset exists when an entity has a right to consideration in exchange for goods or services transferred to a customer. Our consolidated balance sheet as of December 31, 2019, included the contract assets and liabilities in the table below.

	December 31, 2019			December 31, 2018
	(In thousands)
Contract assets	$	5,675		$	1,818
Contract liabilities	$	(650	)	$	(1,821	)

The contract assets and liabilities include both lease and service components. We recognized $0.6 million of revenue that was previously included in contract liability as of December 31, 2018, during the twelve months ended December 31, 2019. During the twelve months ended December 31, 2018, we recognized $2.7 million that was previously included in contract liability as of January 1, 2018. During the twelve months ended December 31, 2019 and 2018, we also recognized $3.9 million and $1.8 million respectively, of revenue included in contract assets at December 31, 2019.

As of December 31, 2019, we expect to recognize 2.4 billion in revenue related to our unfulfilled performance obligations under the terms of our long-term throughput agreements and operating leases expiring in 2020 through 2036. These agreements provide

- 81 -

for changes in the minimum revenue guarantees annually for increases or decreases in the Producer Price Index (“PPI”) or Federal Energy Regulatory Commission (“FERC”) index, with certain contracts having provisions that limit the level of the rate increases or decreases. We expect to recognize revenue for these unfulfilled performance obligations as shown in the table below (amounts shown in table include both service and lease revenues):

Years Ending December 31,	(In millions)
2020	$	369
2021	359
2022	331
2023	294
2024	257
Thereafter	825
Total	$	2,435

Payment terms under our contracts with customers are consistent with industry norms and are typically payable within 10 to 30 days of the date of invoice.

Disaggregated revenues are as follows:

	Years Ended December 31,
	2019		2018		2017
	(In thousands)
Pipelines	$	292,631	$	283,507	$	235,040
Terminals, tanks and loading racks	160,467		147,534		142,418
Refinery processing units	79,679		75,179		76,904
	$	532,777	$	506,220	$	454,362

During the year ended December 31, 2019, lease revenues amounted to $378.3 million, and service revenues amounted to $154.5 million. Both of these revenues were recorded within affiliates and third parties revenues on our consolidated statement of income.

Note 5: Leases

We adopted ASC 842 effective January 1, 2019, and elected to adopt using the modified retrospective transition method and practical expedients, both of which are provided as options by the standard and further defined in Note 1.

Lessee Accounting

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

As a lessee, we lease land, buildings, pipelines, transportation and other equipment to support our operations. These leases can be categorized into operating and finance leases. Operating leases are recorded in operating lease right-of-use assets and current and noncurrent operating lease liabilities on our consolidated balance sheet. Finance leases are included in properties and equipment, current finance lease liabilities and noncurrent finance lease liabilities on our consolidated balance sheet.

When renewal options are defined in a lease, our lease term includes an option to extend the lease when it is reasonably certain we will exercise that option. Leases with a term of 12 months or less are not recorded on our balance sheet, and lease expense is accounted for on a straight-line basis. In addition, as a lessee, we separate non-lease components that are identifiable and exclude them from the determination of net present value of lease payment obligations.

- 82 -

Our leases have remaining terms of 1 to 25 years, some of which include options to extend the leases for up to 10 years.

Lease Obligations

We have finance lease obligations related to vehicle leases with initial terms of 33 to 48 months. The total cost of assets under finance leases was $7.0 million and $5.8 million as of December 31, 2019 and December 31, 2018, respectively, with accumulated depreciation of $4.5 million and $4.3 million as of December 31, 2019 and December 31, 2018, respectively. We include depreciation of finance leases in depreciation and amortization in our consolidated statements of income.

In addition, we have a finance lease obligation related to a pipeline lease with an initial term of 10 years with one remaining subsequent renewal option for an additional 10 years. The right of use asset associated with this obligation was derecognized as discussed under the lessor accounting disclosures below.

Supplemental balance sheet information related to leases was as follows (in thousands, except for lease term and discount rate):

Lessor Accounting

As discussed in Note 4, the majority of our contracts with customers meet the definition of a lease. See Note 4 for further discussion of the impact of adoption of this standard on our activities as a lessor.

Customer contracts that contain leases are generally classified as either operating leases, direct finance leases or sales-type leases. We consider inputs such as the lease term, fair value of the underlying asset and residual value of the underlying assets when assessing the classification.

Substantially all of the assets supporting contracts meeting the definition of a lease have long useful lives, and we believe these assets will continue to have value when the current agreements expire due to our risk management strategy for protecting the residual fair value of the underlying assets by performing ongoing maintenance during the lease term. HFC generally has the option to purchase assets located within HFC refinery boundaries, including refinery tankage, truck racks and refinery processing units, at fair market value when the related agreements expire.

One of our throughput agreements with HFC was renewed during the year ended December 31, 2019. Certain components of this agreement met the criteria of sales-type leases since the underlying assets are not expected to have an alternative use at the end of the lease term to anyone besides HFC. Under sales-type lease accounting, at the commencement date, the lessor recognizes a net investment in the lease and derecognizes the underlying assets with the difference recorded as gain or loss arising from the lease. Therefore, we recognized a gain on sales-type leases during the year ended December 31, 2019 composed of the following:

	(In thousands)
Net investment in leases	$	122,800
Properties and equipment, net	(15,031		)
Operating lease right-of-use assets, net	(72,603		)
Gain on sales-type leases	$	35,166

This sales-type lease transaction, including the related gain, was a non-cash transaction.

- 84 -

Lease income recognized was as follows:

	Years Ended December 31,
	2019		2018
	(In thousands)
Operating lease revenues	$	373,517	$	278,624
Direct financing lease interest income	$	2,082	$	2,108
Gain on sales-type leases	$	35,166	$	—
Sales-type lease interest income	$	3,340	$	—
Lease revenues relating to variable lease payments not included in measurement of the sales-type lease receivable	$	4,794	$	—

For our sales-type leases, we included customer obligations related to minimum volume requirements in guaranteed minimum lease payments. Portions of our minimum guaranteed pipeline tariffs for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. We recognized any billings for throughput volumes in excess of minimum volume requirements as variable lease payments, and these variable lease payments were recorded in lease revenues.

As discussed in Notes 1 and 4, prior to the adoption of ASC 842, contract consideration was bifurcated between operating lease and service revenues.

Annual minimum undiscounted lease payments under our leases were as follows as of December 31, 2019:

	Operating		Finance		Sales-type
Years Ending December 31,	(In thousands)
2020	$	310,941	$	2,112	$	9,501

Note 6: Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. 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:

- 85 -

• (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.

Financial Instruments

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

The carrying amounts and estimated fair values of our senior notes were as follows:

		December 31, 2019				December 31, 2018
Financial Instrument	Fair Value Input Level	Carrying Value		Fair Value		Carrying Value		Fair Value
		(In thousands)
Liabilities:
6.0% Senior Notes	Level 2	$	496,531	$	522,045	$	495,900	$	488,310

Level 2 Financial Instruments

Our senior notes are measured at fair value using Level 2 inputs. The fair value of the senior notes is based on market values provided by a third-party bank, which were derived using market quotes for similar type debt instruments. See Note 10 for additional information.

Non-Recurring Fair Value Measurements

For gains on sales-type leases recognized during the third quarter of 2019, the estimated fair value of the underlying leased assets at contract inception and the present value of the estimated unguaranteed residual asset at the end of the lease term are used in determining the net investment in leases and related gain on sales-type leases recorded.  The asset valuation estimates include Level 3 inputs based on a replacement cost valuation method.    

Note 7: Properties and Equipment 

The carrying amounts of our properties and equipment are as follows:

	December 31, 2019		December 31, 2018
	(In thousands)
Pipelines, terminals and tankage	$	1,602,231	$	1,571,338
Refinery assets	348,093		347,338
Land and right of way	86,190		86,298
Construction in progress	10,930		23,482
Other	14,110		41,250
	2,061,554		2,069,706
Less accumulated depreciation	594,455		531,051
	$	1,467,099	$	1,538,655

We capitalized $29 thousand and $0.3 million in interest related to construction projects during the years ended December 31, 2019 and 2018, respectively.

- 86 -

Depreciation expense was $82.6 million, $83.3 million, and $71.1 million for the years ended December 31, 2019, 2018 and 2017, respectively, and includes depreciation of assets acquired under capital leases. Asset abandonment charges of $1.3 million, $1.0 million and $0.3 million for assets permanently removed from service were included in depreciation expense for the years ended December 31, 2019, 2018 and 2017, respectively.

Note 8: Intangible Assets

Intangible assets include transportation agreements and customer relationships that represent a portion of the total purchase price of certain assets acquired from Delek in 2005, from HFC in 2008 prior to HEP becoming a consolidated VIE of HFC, from Plains in 2017, and from other minor acquisitions in 2018.

The carrying amounts of our intangible assets are as follows:

	Useful Life	December 31, 2019		December 31, 2018
		(In thousands)
Delek transportation agreement	30 years	$	59,933	$	59,933
HFC transportation agreements	10-15 years	75,131		75,131
Customer relationships	10 years	69,683		69,683
Other	20 years	50		50
		204,797		204,797
Less accumulated amortization		103,475		89,468
		$	101,322	$	115,329

Amortization expense was $14.0 million, $14.5 million and $7.6 million for the years ending December 31, 2019, 2018 and 2017, respectively. We estimate amortization expense to be $14.0 million for each of the next three years and $9.9 million in 2023 and $9.1 million in 2024.

We have additional transportation agreements with HFC resulting from historical transactions consisting of pipeline, terminal and tankage assets contributed to us or acquired from HFC. These transactions occurred while we were a consolidated variable interest entity of HFC; therefore, our basis in these agreements is zero and does not reflect a step-up in basis to fair value.

Note 9: Employees, Retirement and Incentive Plans

Direct support for our operations is provided by Holly Logistic Services, L.L.C., ("HLS"), an HFC subsidiary, which utilizes personnel employed by HFC who are dedicated to performing services for us. Their costs, including salaries, bonuses, payroll taxes, benefits and other direct costs, are charged to us monthly in accordance with an omnibus agreement that we have with HFC. These employees participate in the retirement and benefit plans of HFC. Our share of retirement and benefit plan costs was $7.3 million, $6.9 million and $5.9 million for the years ended December 31, 2019, 2018 and 2017, respectively. These costs include retirement costs of $3.4 million, $3.1 million and $2.7 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Under HLS’s secondment agreement with HFC (the “Secondment Agreement”), certain employees of HFC are seconded to HLS to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs related to these employees.

We have a Long-Term Incentive Plan for employees and non-employee directors who perform services for us. The Long-Term Incentive Plan consists of four components: restricted or phantom units, performance units, unit options and unit appreciation rights. Our accounting policy for the recognition of compensation expense for awards with pro-rata vesting (a significant proportion of our awards) is to expense the costs ratably over the vesting periods. We account for forfeitures on an estimated basis.

As of December 31, 2019, we have two types of incentive-based awards outstanding, which are described below. The compensation cost charged against income was $2.5 million, $3.0 million and $2.7 million for the years ended December 31, 2019, 2018 and 2017, respectively. We currently purchase units in the open market instead of issuing new units for settlement of all unit awards

- 87 -

under our Long-Term Incentive Plan. As of December 31, 2019, 2,500,000 units were authorized to be granted under our Long-Term Incentive Plan, of which 1,113,537 have not yet been granted, assuming no forfeitures of the unvested units and full achievement of goals for the unvested performance units.

Restricted and Phantom Units

Under our Long-Term Incentive Plan, we grant restricted units to non-employee directors and phantom units to selected employees who perform services for us, with most awards vesting over a period of one to three years. We previously granted restricted units to selected employees who perform services for us, which vest over a period of three years. Although full ownership of the units does not transfer to the recipients until the units vest, the recipients have distribution rights on these units from the date of grant, and the recipients of the restricted units have voting rights on the restricted units from the date of grant.

The fair value of each restricted or phantom unit award is measured at the market price as of the date of grant and is amortized on a straight-line basis over the requisite service period for each separately vesting portion of the award.

A summary of restricted and phantom unit activity and changes during the year ended December 31, 2019, is presented below: 

Restricted and Phantom Units	Units		Weighted- Average Grant-Date Fair Value
Outstanding at January 1, 2019 (nonvested)	138,016		$	31.35
Granted	95,300		23.52
Vesting and transfer of common units to recipients	(64,732	)	31.96
Forfeited	(23,379	)	29.57
Outstanding at December 31, 2019 (nonvested)	145,205		$	26.22

The grant date fair values of restricted units that were vested and transferred to recipients during the years ended December 31, 2019, 2018 and 2017 were $2.1 million, $2.5 million and $2.0 million, respectively. As of December 31, 2019, there was $2.3 million of total unrecognized compensation expense related to unvested restricted and phantom unit grants, which is expected to be recognized over a weighted-average period of 1.6 years. For the years ended December 31, 2018 and 2017, the grant date price applied to the number of restricted units awarded was $29.30 and $35.59 respectively.

Performance Units

Under our Long-Term Incentive Plan, we grant performance units to selected executives who perform services for us. Performance units granted are payable in common units at the end of a three-year performance period based upon meeting certain criteria over the performance period. Under the terms of our performance unit grants, some awards are subject to the growth in our distributable cash flow per common unit over the performance period while other awards are subject to "financial performance" and "market performance." Financial performance is based on meeting certain earnings before interest, taxes, depreciation and amortization ("EBITDA") targets, while market performance is based on the relative standing of total unitholder return achieved by HEP compared to peer group companies. The number of units ultimately issued under these awards can range from 50% to 150% or 0% to 200%. As of December 31, 2019, estimated unit payouts for outstanding nonvested performance unit awards ranged between 100% and 150% of the target number of performance units granted.

Although common units are not transferred to the recipients until the performance units vest, the recipients have distribution rights with respect to the common units from the date of grant.

A summary of performance unit activity and changes for the year ended December 31, 2019, is presented below:

Performance Units	Units
Outstanding at January 1, 2019 (nonvested)	51,748
Granted	17,010
Vesting and transfer of common units to recipients	(10,113	)
Forfeited	(5,200	)
Outstanding at December 31, 2019 (nonvested)	53,445

- 88 -

The grant date fair values of performance units vested and transferred to recipients were $0.3 million, $0.1 million and $0.1 million for the years ended December 31, 2019, 2018 and 2017, respectively. Based on the weighted average fair value of performance units outstanding at December 31, 2019, of $1.6 million, there was $0.6 million of total unrecognized compensation expense related to nonvested performance units, which is expected to be recognized over a weighted-average period of 1.6 years.

During the year ended December 31, 2019, we paid $1.5 million for the purchase of our common units in the open market for the issuance and settlement of unit awards under our Long-Term Incentive Plan.

Note 10: Debt

Credit Agreement

We have a $1.4 billion senior secured revolving credit facility (the “Credit Agreement”) expiring in July 2022. The Credit Agreement is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. The Credit Agreement is also available to fund letters of credit up to a $50 million sub-limit, and it contains an accordion feature giving us the ability to increase the size of the facility by up to $300 million with additional lender commitments.

Our obligations under the Credit Agreement are collateralized by substantially all of our assets, and indebtedness under the Credit Agreement is guaranteed by our material, wholly-owned subsidiaries. The Credit Agreement requires us to maintain compliance

with certain financial covenants consisting of total leverage, senior secured leverage, and interest coverage. It also limits or restricts our ability to engage in certain activities. If, at any time prior to the expiration of the Credit Agreement, HEP obtains two investment grade credit ratings, the Credit Agreement will become unsecured and many of the covenants, limitations, and restrictions will be eliminated.

Indebtedness under the Credit Agreement bears interest, at our option, at either (a) the reference rate as announced by the administrative agent plus an applicable margin (ranging from 0.50% to 1.50%) or (b) at a rate equal to LIBOR plus an applicable margin (ranging from 1.50% to 2.50%). In each case, the applicable margin is based upon the ratio of our funded debt (as defined in the Credit Agreement) to EBITDA (earnings before interest, taxes, depreciation and amortization, as defined in the Credit Agreement). The weighted-average interest rates on our Credit Agreement borrowings for both the years ending December 31, 2019 and 2018, were 4.24%. We incur a commitment fee on the unused portion of the Credit Agreement at an annual rate ranging from 0.25% to 0.50% based upon the ratio of our funded debt to EBITDA for the four most recently completed fiscal quarters.

We may prepay all loans at any time without penalty, except for tranche breakage costs. If an event of default exists under the Credit Agreement, the lenders will be able to accelerate the maturity of all loans outstanding and exercising other rights and remedies. We were in compliance with the covenants as of December 31, 2019.

Senior Notes

As of December 31, 2019, we had $500 million aggregate principal amount of 6% senior unsecured notes due in 2024 (the "6% Senior Notes"). The 6% Senior Notes were unsecured and imposed certain restrictive covenants, including limitations on our ability to incur additional indebtedness, make investments, sell assets, incur certain liens, pay distributions, enter into transactions with affiliates and enter into mergers. We were in compliance with the restrictive covenants for the 6% Senior Notes as of December 31, 2019.

On February 4, 2020, we closed a private placement of $500 million in aggregate principal amount of 5% senior unsecured notes due in 2028 (the "5% Senior Notes"). On February 5, 2020, we redeemed the existing $500 million 6% Senior Notes at a redemption cost of $522.5 million. We will record any early extinguishment losses associated with this redemption during the first quarter of 2020. We funded the $522.5 million redemption with proceeds from the issuance of our 5% Senior Notes and borrowings under our Credit Agreement.

The 5% Senior Notes are unsecured and impose certain restrictive covenants, including limitations on our 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 5% Senior Notes are rated investment grade by either Moody’s or 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 at varying premiums over face value under the 5% Senior Notes.

- 89 -

Indebtedness under the 5% Senior Notes is guaranteed by our wholly-owned subsidiaries (other than Holly Energy Finance Corp. and certain immaterial subsidiaries).

On January 4, 2017, we redeemed the $300 million aggregate principal amount of 6.5% senior notes due in 2020 (the "6.5% Senior Notes") at a redemption cost of $309.8 million, at which time we recognized a $12.2 million early extinguishment loss consisting of a $9.8 million debt redemption premium and unamortized discount and financing costs of $2.4 million. We funded the redemption with borrowings under our Credit Agreement.

Our purchase and contribution agreements with HFC with respect to the intermediate pipelines acquired in 2005 and the crude pipelines and tankage assets acquired in 2008, restrict us from selling these pipelines and terminals acquired from HFC.

Note 11: Commitments and Contingencies

We lease certain facilities and pipelines under operating leases and finance leases, most of which contain renewal options. These operating leases have various termination dates through 2035. See Note 5 of Notes to Consolidated Financial Statements for a schedule of annual minimum undiscounted lease payments under our leases as of December 31, 2019.

Rental expense charged to operations was $6.6 million, $9.8 million and $9.1 million for the years ended December 31, 2019, 2018 and 2017, respectively. As of December 31, 2019, we expect to receive aggregate payments totaling $1.4 million over the life of our noncancelable sublease of office space, expiring in 2026.

We also have other long-term contractual obligations consisting of long-term site service agreements with HFC, expiring in 2058 through 2066, for the provision of certain facility services and utility costs that relate to our assets located at HFC’s refinery facilities. We are presenting obligations for the full term of these agreements; however, the agreements can be terminated with 180 day notice if we cease to operate the applicable assets.

In addition, we have long-term contractual obligations associated with rights-of-way agreements, which have various termination dates through 2061. The related payments below include only obligations under the remaining non-cancelable terms of these agreements at December 31, 2019.

At December 31, 2019, these minimum future contractual obligations and other miscellaneous obligations having terms in excess of one year are as follows:

Note 12: Related Party Transactions

We serve HFC’s refineries under long-term pipeline, terminal and tankage throughput agreements, and refinery processing unit tolling agreements expiring from 2021 to 2036 and revenues from these agreements accounted for approximately 77% of our total revenues for the year ended December 31, 2019. Under these agreements, HFC agrees to transport, store, and process throughput volumes of refined product, crude oil and feedstocks on our pipelines, terminals, tankage, loading rack facilities and refinery processing units that result in minimum annual payments to us. These minimum annual payments or revenues are subject to annual rate adjustments on July 1st each year based on the Producer Price Index (“PPI”) or FERC index. As of December 31, 2019, these agreements with HFC require minimum annualized payments to us of $348.1 million.

If HFC fails to meet its minimum volume commitments under the agreements in any quarter, it will be required to pay us the amount of any shortfall in cash by the last day of the month following the end of the quarter. Under certain of these agreements, a shortfall payment may be applied as a credit in the following four quarters after its minimum obligations are met.

Under certain provisions of the Omnibus Agreement, we pay HFC an annual administrative fee (currently $2.6 million) for the provision by HFC or its affiliates of various general and administrative services to us. This fee does not include the salaries of personnel employed by HFC who perform services for us on behalf of HLS or the cost of their employee benefits, which are charged to us separately by HFC. Also, we reimburse HFC and its affiliates for direct expenses they incur on our behalf.

Related party transactions with HFC are as follows:

• Revenues received from HFC were $411.8 million, $397.8 million and $377.1 million for the years ended December 31, 2019, 2018 and 2017, respectively.

• HFC charged us general and administrative services under the Omnibus Agreement of $2.6 million for December 31, 2019 and $2.5 million for each of the years ended December 31, 2018 and 2017.

• We reimbursed HFC for costs of employees supporting our operations of $55.1 million, $51.7 million and $46.6 million for the years ended December 31, 2019, 2018 and 2017, respectively.

• HFC reimbursed us $13.9 million, $10.0 million and $7.2 million for the years ended December 31, 2019, 2018 and 2017, respectively, for expense and capital projects.

• We distributed $150.0 million and $146.8 million, in the years ended December 31, 2019 and 2018, respectively, to HFC as regular distributions on its common units and $130.7 million in the year ended December 31, 2017 to HFC as regular distributions on its common units and general partner interest, including general partner incentive distributions.

• Accounts receivable from HFC were $49.7 million and $46.8 million at December 31, 2019 and 2018, respectively.

• Accounts payable to HFC were $16.7 million and $14.2 million at December 31, 2019 and 2018, respectively.

• Revenues for the years ended December 31, 2019, 2018 and 2017 include $0.5 million, $3.1 million and $4.8 million, respectively, of shortfall payments billed to HFC in 2018, 2017 and 2016, respectively. Deferred revenue in the consolidated balance sheets at December 31, 2019 and 2018, includes $0.5 million and $1.7 million, respectively, relating to certain shortfall billings to HFC.

• We received direct financing lease payments from HFC for use of our Artesia and Tulsa railyards of $2.1 million, $2.0 million and $0.5 million for the years ended December 31, 2019, 2018 and 2017, respectively.

• We recorded a gain on sales-type leases with HFC of $35.2 million during the year ended December 31, 2019, and we received sales-type lease payments of $4.8 million from HFC that were not included in revenues for the year ended December 31, 2019.

• On October 31, 2017, we closed on an equity restructuring transaction with HEP Logistics, a wholly-owned subsidiary of HFC and the general partner of HEP, pursuant to which the incentive distribution rights held by HEP Logistics were canceled, and HEP Logistics' 2% general partner interest in HEP was converted into a non-economic general partner interest in HEP. In consideration, we issued 37,250,000 of our common units to HEP Logistics. In addition, HEP Logistics agreed to waive $2.5 million of limited partner cash distributions for each of twelve consecutive quarters beginning with the first quarter the units issued as consideration were eligible to receive distributions. This waiver of limited partner cash distributions will expire after the cash distribution for the second quarter of 2020, which will be made during the third quarter of 2020.

- 92 -

Note 13: Partners’ Equity, Income Allocations and Cash Distributions

At December 31, 2019, HFC held 59,630,030 of our common units, constituting a 57% limited partner interest in us and held the non-economic general partner interest. Additionally, HFC owned all incentive distribution rights through October 31, 2017, when an agreement was reached with HEP Logistics, our general partner, impacting its equity interest in HEP including canceling these incentive distribution rights. See Note 1 for a description of this equity restructuring transaction.

Common Unit Private Placement

On January 25, 2018, we entered into a common unit purchase agreement in which certain purchasers agreed to purchase in a private placement 3,700,000 common units representing limited partnership interests, at a price of $29.73 per common unit. The private placement closed on February 6, 2018, and we received proceeds of approximately $110 million, which were used to repay indebtedness under our Credit Agreement. After this common unit issuance, HFC owned a 57% limited partner interest in us.

Continuous Offering Program

We have a continuous offering program under which we may issue and sell common units from time to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million. As of December 31, 2019, HEP had issued 2,413,153 units under this program, providing $82.3 million in gross proceeds.

Allocations of Net Income

Net income attributable to the partners is allocated to the partners based on their weighted-average ownership percentage during the period.

Prior to the equity restructuring of the general partner interest owned by HEP Logistics described in Note 1 that occurred on October 31, 2017, net income attributable to the partners was allocated between limited partners and the general partner interest in accordance with the provisions of the partnership agreement. HEP net income allocated to the general partner included incentive distributions that were declared subsequent to quarter end. After incentive distributions and other priority allocations are allocated to the general partner, the remaining net income attributable to HEP was allocated to the partners based on their weighted-average ownership percentage during the period.

The following table presents the allocation of the general partner interest in net income for the periods presented below: 

	Years Ended December 31,
	2019		2018		2017
	(In thousands)
General partner interest in net income	$	—	$	—	$	919
General partner incentive distribution	—		—		34,128
Total general partner interest in net income	$	—	$	—	$	35,047

Cash Distributions

We consider regular cash distributions to unitholders on a quarterly basis, although there is no assurance as to the future cash distributions since they are dependent upon future earnings, cash flows, capital requirements, financial condition and other factors.

Within 45 days after the end of each quarter, we distribute all of our available cash (as defined in our partnership agreement) to unitholders of record on the applicable record date. The amount of available cash generally is all cash on hand at the end of the quarter; less the amount of cash reserves established by our general partner to provide for the proper conduct of our business, comply with applicable laws, any of our debt instruments, or other agreements; or provide funds for distributions to our unitholders and to our general partner for any one or more of the next four quarters; plus all cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter.

- 93 -

Prior to the equity restructuring transaction discussed in Note 1, we made distributions in the manner displayed in the table below. Subsequent to the financial restructuring, distributions are made equally to all common unit holders regardless of the amount of the distribution per unit.

	Total Quarterly Distribution	Marginal Percentage Interest in Distributions
	Target Amount	Unitholders	General Partner
Minimum quarterly distribution	$0.25	98%	2%
First target distribution	Up to $0.275	98%	2%
Second target distribution	above $0.275 up to $0.3125	85%	15%
Third target distribution	above $0.3125 up to $0.375	75%	25%
Thereafter	Above $0.375	50%	50%

On January 23, 2020, we announced our cash distribution for the fourth quarter of 2019 of $0.6725 per unit. The distribution was payable on all common units and was paid February 13, 2020, to all unitholders of record on February 3, 2020. However, HEP Logistics waived $2.5 million in limited partner cash distributions due to them as discussed in Note 1.

The following table presents the allocation of our regular quarterly cash distributions to the general and limited partners for the periods in which they apply. Our distributions are declared subsequent to quarter end; therefore, the amounts presented do not reflect distributions paid during the periods presented below.

	Years Ended December 31,
	2019		2018		2017
	(In thousands, except per unit data)
General partner interest in distribution	$	—	$	—	$	2,335
General partner incentive distribution	—		—		34,128
Total general partner distribution	—		—		36,463
Limited partner distribution	273,768		269,284		206,846
Total regular quarterly cash distribution	$	273,768	$	269,284	$	243,309
Cash distribution per unit applicable to limited partners	$	2.6875	$	2.6475	$	2.5475

As a master limited partnership, we distribute our available cash, which historically has exceeded our net income attributable to HEP because depreciation and amortization expense represents a non-cash charge against income. The result is a decline in our partners’ equity since our regular quarterly distributions have exceeded our quarterly net income attributable to HEP. Additionally, if the asset contributions and acquisitions from HFC had occurred while we were not a consolidated variable interest entity of HFC, our acquisition cost, in excess of HFC’s historical basis in the transferred assets, would have been recorded in our financial statements at the time of acquisition as increases to our properties and equipment and intangible assets instead of decreases to our partners’ equity.

Note 14: Net Income Per Limited Partner Unit

Net income per unit applicable to the limited partners was computed using the two-class method since we had more than one class of participating securities during the period from January 1, 2017 through October 31, 2017.  The classes of participating securities during this period included common units, general partner units and IDRs. Due to the equity restructuring transaction described in Note 1, as of November 1, 2017, we had one class of security outstanding, common units. To the extent net income attributable to the partners exceeds or is less than cash distributions, this difference is allocated to the partners based on their weighted-average ownership percentage during the period, after consideration of any priority allocations of earnings.  The dilutive securities are immaterial for all periods presented.

See Note 1 for a description of the equity restructuring of the general partner interest owned by HEP Logistics, our general partner, and its IDRs that occurred on October 31, 2017. After this equity restructuring, the general partner interest is no longer entitled

- 94 -

to any distributions and none were made on the general partner interest after October 31, 2017. In connection with this equity restructuring, HEP issued 37,250,000 of its common units to HEP Logistics on October 31, 2017.

When our financial statements are retrospectively adjusted after a dropdown transaction, the earnings of the acquired business, prior to the closing of the transaction, are allocated entirely to our general partner and presented as net income (loss) attributable to Predecessors. The earnings per unit of our limited partners prior to the close of the transaction do not change as a result of the dropdown. After the closing of a dropdown transaction, the earnings of the acquired business are allocated in accordance with our partnership agreement as previously described.

For purposes of applying the two-class method including the allocation of cash distributions in excess of earnings, net income per limited partner unit is computed as follows:

Note 15: Environmental

We expensed $0.5 million, $0.8 million and $0.5 million for the years ended December 31, 2019, 2018 and 2017, respectively, for environmental remediation obligations. The accrued environmental liability related to environmental clean-up projects for which we have assumed liability or for which indemnity provided by HFC has expired reflected in our consolidated balance sheets was $5.5 million and $6.3 million as of the years ended December 31, 2019 and 2018, respectively, of which $3.5 million and $4.3 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.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers. As of both December 31, 2019 and 2018, our consolidated balance sheets included additional accrued environmental liabilities of $0.5 million for HFC indemnified liabilities, and other assets included equal and offsetting balances representing amounts due from HFC related to indemnifications for environmental remediation liabilities.

Note 16: Operating Segments

Our operations are organized into two reportable operating segments: pipelines and terminals, and refinery processing units. These segments adhere to the accounting polices used for our consolidated financial statements. For a discussion of these accounting policies and a summary of our reportable operating segments' assets and derivation of revenue, see Note 1.

Pipelines and terminals have been aggregated as one reportable segment as both pipelines and terminals (1) have similar economic characteristics, (2) similarly provide logistics services of transportation and storage of petroleum products, (3) similarly support the petroleum refining business, including distribution of its products, (4) have principally the same customers and (5) are subject to similar regulatory requirements.

We evaluate the performance of each segment based on its respective operating income. Certain general and administrative expenses and interest and financing costs are excluded from segment operating income as they are not directly attributable to a specific reportable segment. Identifiable assets are those used by the segment, whereas other assets are principally equity method investments, cash, deposits and other assets that are not associated with a specific reportable segment.

Note 18: Supplemental Guarantor/Non-Guarantor Financial Information

Obligations of HEP (“Parent”) under the 6% Senior Notes have been jointly and severally guaranteed by each of its direct and indirect 100% owned subsidiaries (“Guarantor Subsidiaries”). These guarantees are full and unconditional, subject to certain customary release provisions. These circumstances include (i) when a Guarantor Subsidiary is sold or sells all or substantially all of its assets, (ii) when a Guarantor Subsidiary is declared “unrestricted” for covenant purposes, (iii) when a Guarantor Subsidiary's guarantee of other indebtedness is terminated or released and (iv) when the requirements for legal defeasance or covenant defeasance or to discharge the senior notes have been satisfied.

On February 4, 2020, we closed a private placement of the 5% Senior Notes, and on February 5, 2020, we redeemed the existing 6% Senior Notes (see Note 10). Obligations of HEP (“Parent”) under the 5% Senior Notes have been jointly and severally guaranteed by each of its direct and indirect 100% owned subsidiaries (“Guarantor Subsidiaries”). These guarantees are full and unconditional, subject to certain customary release provisions. These circumstances include (i) when a Guarantor Subsidiary is sold or sells all or substantially all of its assets, (ii) when a Guarantor Subsidiary is declared “unrestricted” for covenant purposes, (iii) when a Guarantor Subsidiary's guarantee of other indebtedness is terminated or released and (iv) when the requirements for legal defeasance or covenant defeasance or to discharge the senior notes have been satisfied.

Board Leadership Structure

The Board of Directors of HLS (the “Board”) is responsible for selecting the Board leadership structure that is in the best interest of HLS and HEP. Currently, Mr. Jennings serves as Chairman of the Board and as the Chief Executive Officer of HLS. Independent directors and management have different perspectives and roles in strategy development. The independent directors on the Board bring experience, oversight and expertise from outside HLS, HEP and the industry, while the Chief Executive Officer brings HLS and HEP experience and expertise. The Board believes the combined role of Chairman of the Board and Chief Executive Officer working with the lead independent director (the “Presiding Director”), is in the best interest of unitholders at this time because the combined role for HLS provides balance between strategy development and independent oversight of management, both of which are particularly useful in HLS’s role as general partner.

Chairman of the Board

Mr. Jennings was selected by the directors of HLS to serve as the Chairman of the Board. The Chairman has the following responsibilities:

• designating and calling meetings of the Board;

• presiding at all Board meetings;

• consulting with management on Board and committee meeting agendas;

• facilitating teamwork and communication between the Board and management; and

• acting as a liaison between management and the Board.

Presiding Director

Larry R. Baldwin, an independent director, was appointed by the non-management directors of HLS to serve as the Presiding Director of the Board. The Presiding Director has the following responsibilities:

• presiding at all executive sessions of the non-management directors of the Board;

• consulting with management on Board and committee meeting agendas;

• facilitating teamwork and communication between the non-management directors and management; and

• acting as a liaison in appropriate instances between management and the non-management directors, including advising the Chairman of the Board and Chief Executive Officer on the efficiency of the Board meetings

- 109 -

Persons wishing to communicate with the non-employee directors are invited to email the Presiding Director at presiding.director.HEP@hollyenergy.com or write to: Larry R. Baldwin, Presiding Director, c/o Secretary, Holly Logistic Services, L.L.C., 2828 N. Harwood, Suite 1300, Dallas, Texas 75201-1507. Communications to the Board generally may be sent certified mail to Holly Logistic Services, L.L.C., 2828 N. Harwood, Suite 1300, Dallas, Texas 75201-1507, Attention: Secretary. The Secretary will forward all communication to the appropriate director or directors, other than those communications that are merely solicitations for products or services or relate to matters that are of a type that are clearly improper or irrelevant to the functioning of the Board or the business and affairs of HLS and HEP.

Risk Management

The Board has an active role in overseeing management of the risks affecting HLS and HEP, including cyber security. The Board regularly reviews information regarding HLS and HEP’s credit, liquidity and business and operations, as well as the risks associated with each. The Board committees are also engaged in overseeing risk associated with HLS and HEP.

• The Compensation Committee oversees the management of risks relating to HLS’s compensation plans and arrangements.

• The Audit Committee oversees management of financial reporting and controls risks.

• The Conflicts Committee oversees specific matters that it or the Board believes may involve conflicts of interest with HFC.

While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is ultimately responsible for the risk management of HLS and HEP and is regularly informed on these matters through committee and senior management presentations.

The sole member of HLS manages risks associated with the independence of the Board. The Board also receives input and reports from HLS’s risk management oversight committee on management’s views of the risks facing HLS and HEP. The risk management oversight committee is made up of management personnel, none of whom serve on the Board and all of whom have a range of different backgrounds, skills and experiences with regard to the operational, financial and strategic risk profile of HLS and HEP. The risk management oversight committee supports the efforts of the Board and the Board committees to monitor and evaluate guidelines and policies governing HLS’s and HEP’s risk assessment and management.

Director Qualifications

The Board believes that it is necessary for each of HLS’s directors to possess a variety of qualities and skills. When searching for new candidates, the sole member of HLS considers the evolving needs of the Board and searches for candidates that fill any current or anticipated future needs. The Board also believes that all directors must possess a considerable amount of business management, business leadership and educational experience. When considering director candidates, the sole member of HLS first considers a candidate’s management experience and then considers issues of judgment, background, stature, conflicts of interest, integrity, ethics, industry knowledge, ability to commit adequate time to the Board, and commitment to the goal of maximizing unitholder value. The sole member of HLS also focuses on issues of diversity, such as diversity of race, gender, age, culture, thought and geography. In considering candidates for the Board, the sole member of HLS considers the entirety of each candidate’s credentials in the context of these standards. All our directors bring to the Board executive leadership experience derived from their service in many areas.

Pursuant to the Governance Guidelines of HLS and HEP, a director must submit his or her resignation to the Board in the first quarter of the calendar year in which the director will attain the age of 75 or greater. If the resignation is accepted by the Board, the resignation will be effective on December 31 of the year in which the resignation was accepted by the Board.

Director Independence

The Board has determined that Larry R. Baldwin, Christine B. LaFollete, James H. Lee and Eric L. Mattson meet the applicable criteria for independence under the currently applicable rules of the New York Stock Exchange (“NYSE”). Mr. Jennings is not independent because he is an officer of HLS and an employee of HFC. The Board previously determined that, during his service on the Board, Mr. Damiris was not independent because he was an officer of HLS and an employee of HFC.

- 110 -

Audit Committee. The Audit Committee of HLS is currently composed of three directors, Messrs. Baldwin, Lee and Mattson. The Board has determined that each member of the Audit Committee is “independent” as defined by the NYSE listing standards and Rule 10A-3 of the Securities Exchange Act of 1934 (the “Exchange Act”).

Conflicts Committee. The Conflicts Committee of HLS is currently composed of three directors, Messrs. Baldwin and Mattson and Ms. LaFollette. The Board has determined that each member of the Conflicts Committee is “independent” as defined by the NYSE listing standards and Rule 10A-3 of the Exchange Act, as required by the Conflicts Committee Charter.

Compensation Committee. The Compensation Committee of HLS is currently composed of three directors, Messrs. Jennings and Lee and Ms. LaFollette. The Board has determined that Mr. Lee and Ms. LaFollette are “independent” as defined by the NYSE listing standards. Because we are a master limited partnership, Rule 303A.05 of the NYSE Listed Company Manual, which requires a publicly traded company to have a compensation committee composed entirely of independent directors, does not apply to us.

Independence Determinations. In making its independence determinations, the Board considered certain transactions, relationships and arrangements. In determining Ms. LaFollette’s independence, the Board considered that during fiscal year 2017, Akin Gump Strauss Hauer & Feld LLP served as outside counsel to the Conflicts Committee. Ms. LaFollette did not represent the Conflicts Committee of the Board on any matters, and Akin Gump Strauss Hauer & Feld LLP no longer represents the Conflicts Committee of the Board in light of Ms. LaFollette's appointment to the Board.

Code of Ethics 

HLS has adopted a Code of Business Conduct and Ethics that applies to all of its officers, directors and employees, including HLS’s principal executive officer, principal financial officer, and principal accounting officer. The purpose of the Code of Business Conduct and Ethics is to, among other things, affirm HLS’s and HEP’s commitment to a high standard of integrity and ethics. The Code sets forth a common set of values and standards to which all of HLS’s officers, directors and employees must adhere. We will post information regarding an amendment to, or a waiver from, the Code of Business Conduct and Ethics on our website.

Copies of our Governance Guidelines, Audit Committee Charter, Compensation Committee Charter, and Code of Business Conduct and Ethics are available on our website at www.hollyenergy.com. Copies of these documents may also be obtained free of charge upon written request to Holly Energy Partners, L.P., Attention: Director, Investor Relations, 2828 N. Harwood, Suite 1300, Dallas, Texas, 75201-1507.

Each of these committees operates under a written charter adopted by the Board.

During 2019, the Audit Committee held eight meetings, the Conflicts Committee held five meetings, and the Compensation Committee held four meetings.

- 113 -

(1) Mr. Damiris served on the Compensation Committee prior to his retirement from the Board on December 31, 2019.

Audit Committee

The functions of the Audit Committee pursuant to its charter include the following:

• selecting, compensating, retaining and overseeing our independent registered public accounting firm and conducting an annual review of the independence and performance of that firm;

• reviewing the scope and the planning of the annual audit performed by the independent registered public accounting firm;

• overseeing matters related to the internal audit function;

• reviewing the audit report issued by the independent registered public accounting firm;

• reviewing HEP’s annual and quarterly financial statements with management and the independent registered public accounting firm;

• discussing with management HEP’s significant financial risk exposures and the actions management has taken to monitor and control such exposures;

• reviewing and, if appropriate, approving transactions involving conflicts of interest, including related party transactions, when required by HEP’s Code of Business Conduct and Ethics;

• reviewing and discussing HEP’s internal controls over financial reporting with management and the independent registered public accounting firm;

• establishing procedures for the receipt, retention and treatment of complaints received by HEP regarding accounting, internal accounting controls or accounting matters, potential violations of applicable laws, rules and regulations or of our codes, policies and procedures;

• reviewing the type and extent of any non-audit work to be performed by the independent registered public accounting firm and its compatibility with their continued objectivity and independence, and to the extent consistent, pre-approving all non-audit services to be performed;

• reviewing and approving the Audit Committee Report to be included in the Annual Report on Form 10-K; and

Each current member of the Audit Committee has the ability to read and understand fundamental financial statements. The Board has determined that Mr. Baldwin meets the requirements of an “audit committee financial expert” as defined by the rules of the SEC.

Conflicts Committee

The functions of the Conflicts Committee include reviewing specific matters that the Board or the Conflicts Committee believes may involve conflicts of interest with HFC. The Conflicts Committee determines if the resolution of the conflict of interest is fair and reasonable to HEP. Any matters approved by the Conflicts Committee will be conclusively deemed to be fair and reasonable to us, approved by all of our partners, and not a breach by our general partner of any duties it may owe us or our unitholders. In addition, the Conflicts Committee reviews the adequacy of the Conflicts Committee charter on an annual basis.

Compensation Committee

The functions of the Compensation Committee pursuant to its charter include:

• reviewing and approving the goals and objectives of HLS and HEP relevant to the compensation of the officers of HLS for whom the Compensation Committee determines compensation;

- 114 -

• determining compensation for the officers of HLS for whom the Compensation Committee determines compensation;

• reviewing director compensation and making recommendations to the Board regarding the same;

• overseeing the preparation of the Compensation Discussion and Analysis to be included in the Annual Report and preparing the Compensation Committee Report to be included in the Annual Report;

• reviewing the Company’s executive compensation plans with respect to behavioral, operational and other risks;

• administering and making recommendations to the Board with respect to HEP’s equity plan and HLS’s annual incentive plan; and

• reviewing the adequacy of the Compensation Committee charter on an annual basis.

Since the Compensation Committee is not comprised of all independent directors, equity awards, including performance goals applicable to such awards, if applicable, are approved by the full Board.

In January 2018, the Compensation Committee engaged Meridian Compensation Partners, LLC (“Meridian”), as the compensation consultant, to provide advice relating to executive and non-management director compensation matters for the 2019 year. At the time the Compensation Committee selected Meridian as its independent compensation consultant, and the first quarter of every year since engaging Meridian, the Compensation Committee has assessed the independence of Meridian pursuant to SEC rules and considered, among other things, whether Meridian provides any other services to HLS or us, the fees paid by us to Meridian as a percentage of Meridian’s total revenues, the policies of Meridian that are designed to prevent any conflict of interest between Meridian, the Compensation Committee, HLS and us, any personal or business relationship between Meridian and a member of the Compensation Committee or one of HLS’s executive officers and whether Meridian owned any of our common units. In addition to the foregoing, the Compensation Committee annually receives an independence letter from Meridian, as well as other documentation addressing the firm’s independence. Meridian reports exclusively to the Compensation Committee and does not provide any additional services to HLS or us. The Compensation Committee has discussed these considerations and has concluded that Meridian is independent and that neither we nor HLS have any conflicts of interest with Meridian.

Compensation Committee Interlocks and Insider Participation

The members of the Compensation Committee of the Board at year-end 2019 were Messrs. Jennings, Damiris and Lee and Ms. LaFollette. During his service as a member of the Compensation Committee, and prior to his retirement as a director and officer of HLS effective December 31, 2019, Mr. Damiris also served as the Chief Executive Officer and President of HLS. None of the members who served on the Compensation Committee at any time during 2019 had any relationship requiring disclosure under Item 13 of this annual report on Form 10-K entitled “Certain Relationships and Related Transactions, and Director Independence.” No executive officer of HLS served as a member of the compensation committee of another entity that had an executive officer serving as a member of our Board or our Compensation Committee. No executive officer of HLS served as a member of the board of another entity that had an executive officer serving as a member of our Compensation Committee, except that Mr. Damiris also served as the Chief Executive Officer and President of HFC until his retirement as a director and officer of HLS and HFC effective December 31, 2019.

Report of the Audit Committee for the Year Ended December 31, 2019

Management of Holly Logistic Services, L.L.C. is responsible for Holly Energy Partners, L.P.’s system of internal controls over financial reporting. The Audit Committee selected, and the Board approved the selection of Ernst & Young LLP as Holly Energy Partners, L.P.’s independent registered public accounting firm to audit the books, records and accounts of Holly Energy Partners, L.P. for the year ended December 31, 2019. Ernst & Young LLP is responsible for performing an independent audit of Holly Energy Partners, L.P.’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board ("PCAOB") and to issue a report thereon. The Audit Committee also is responsible for selecting, engaging and overseeing the work of the independent registered public accounting firm, which reports directly to the Audit Committee, and evaluating its qualifications and performance. Among other things, to fulfill its responsibilities, the Audit Committee:

• reviewed and discussed Holly Energy Partners, L.P.’s quarterly unaudited consolidated financial statements and its audited annual consolidated financial statements for the year ended December 31, 2019 with management and Ernst & Young LLP, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of

- 115 -

significant judgments and the clarity of disclosures in the financial statements, including those in management’s discussion and analysis thereof;

• discussed with Ernst & Young LLP the matters required to be discussed by the applicable requirements of the PCAOB, the SEC and the New York Stock Exchange;

• discussed with Ernst & Young LLP matters relating to its independence and received the written disclosures and letter from Ernst & Young LLP required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning the firm’s independence;

• discussed with Holly Energy Partners, L.P.’s internal auditors and Ernst & Young LLP the overall scope and plans for their respective audits and met with the internal auditors and Ernst & Young LLP, with and without management present, to discuss the results of their examinations, their evaluations of our internal controls and the overall quality of Holly Energy Partners, L.P.’s financial reporting; and

• considered whether Ernst & Young LLP’s provision of non-audit services to Holly Energy Partners, L.P. is compatible with the auditor’s independence.

The Audit Committee charter requires the Audit Committee to approve in advance all audit and non-audit services to be provided by our independent registered public accounting firm. All fees for audit, audit-related and tax services as well as all other fees presented under Item 14 “Principal Accountant Fees and Services” were approved by the Audit Committee in accordance with its charter.

Based on the foregoing review and discussions and such other matters the Audit Committee deemed relevant and appropriate, the Audit Committee recommended to the Board that the audited consolidated financial statements of Holly Energy Partners, L.P. for the year ended December 31, 2019 be included in Holly Energy Partners, L.P.’s Annual Report on Form 10-K for the year ended December 31, 2019 for filing with the SEC.

Members of the Audit Committee:

Larry R. Baldwin, Chairman

James H. Lee

Director Compensation

The Compensation Committee annually evaluates the compensation program for members of the Board who are not officers or employees of HLS or HFC (“non-employee directors”). Directors who also serve as officers or employees of HLS or HFC do not receive additional compensation for serving on the Board. We reimburse directors for all reasonable expenses incurred in attending Board and Board committee meetings and director continuing education sessions upon submission of appropriate documentation. No meeting fees are paid for Board or Board committee meetings.

For 2019, non-employee directors were entitled to receive a cash retainer, payable in cash, in addition to equity awards described in the following table.

In October 2019, the Board approved non-employee director compensation for 2020. The only change from 2019 was to increase the annual equity retainer from $90,000 to $105,000. In February 2020, the Board appointed Larry R. Baldwin as Presiding Director in light of Mr. Jennings becoming an officer of HFC and HLS in January 2020. In connection with his appointment, the Board approved a presiding director annual cash retainer of $25,000.

	Compensation in 2019		Compensation in 2020
Annual cash retainer	$	100,000	$	100,000
Annual cash retainer for the Presiding Director	$	—	$	25,000
Annual equity retainer of restricted units (1)	$	90,000	$	105,000
Annual cash retainer for the Chairman of the Board (2)	$	75,000	$	75,000
Annual cash retainer for Chairmen of committees (2)	$	25,000	$	25,000

__________________

- 116 -

(1)	The annual award is comprised of a number of restricted units equal to the annual equity retainer divided by the closing price of a common unit on the date of grant, with the number of restricted units rounded up in the case of fractional shares.
(2)	Beginning in 2018, no cash retainer was paid to the Chairman of the Compensation Committee since he also serves as Chairman of the Board. In light of his appointment as an officer of HFC and HLS, beginning January 1, 2020, Mr. Jennings no longer receives any compensation in his capacity as a director of HLS.

Annual Equity Awards

Non-employee directors receive an annual equity award grant under the Holly Energy Partners, L.P. Amended and Restated Long-Term Incentive Plan (the "Long-Term Incentive Plan") in the form of restricted units, with the number of restricted units calculated as described above. Continued service on the Board through the vesting date, which is approximately one year following the date of grant, is required for the restricted units to vest. Vesting of all unvested units will accelerate upon a change in control of HFC, HLS, HEP or HEP Logistics. In addition, vesting of unvested units will accelerate on a pro-rata basis upon the director’s death, total and permanent disability or retirement. Directors are entitled to receive all distributions paid with respect to outstanding restricted units. The distributions are not subject to forfeiture. The directors also have a right to vote with respect to the restricted units.

Non-Qualified Deferred Compensation

Non-employee directors are eligible to participate in the HollyFrontier Corporation Executive Nonqualified Deferred Compensation Plan, which is not tax-qualified under Section 401 of the Internal Revenue Code and allows participants to defer receipt of certain compensation (the “NQDC Plan”). The NQDC Plan allows non-employee directors the ability to defer up to 100% of their cash retainers for a calendar year. Participating directors have full discretion over how their contributions to the NQDC Plan are invested among the investment options. Earnings on amounts contributed to the NQDC Plan are calculated in the same manner and at the same rate as earnings on actual investments. Neither HLS nor HFC subsidizes a participant’s earnings under the NQDC Plan.

None of our non-employee directors participated in the NQDC Plan in 2019. For additional information on the NQDC Plan, see “Compensation Discussion and Analysis–Overview of 2019 Executive Compensation Components and Decisions–Retirement and Benefit Plans–Deferred Compensation Plan” and the narrative preceding the “Nonqualified Deferred Compensation Table.”

Unit Ownership and Retention Policy for Directors

Our directors, other than those that serve as officers of HLS, are subject to the HEP unit ownership and retention policy. Pursuant to the policy, each director is required to hold during service on the Board common units equal in value to at least three times the annual equity retainer paid to non-employee directors. Each subject director is required to meet the applicable requirements within five years of first being subject to the policy.

Directors are also required to continuously own sufficient units to meet the unit ownership and retention requirements once attained. Until directors meet the requirements, they will be required to hold 25% of the units received from any equity award. If a director attains compliance with the policy and subsequently falls below the requirement because of a decrease in the price of our common units, the director will be deemed in compliance provided that the director retains the units then held.

As of December 31, 2019, all of our then-current directors were in compliance with the unit ownership and retention policy or were within the five-year grace period provided in the policy.

Anti-Hedging and Anti-Pledging Policy

All of our directors are subject to our Insider Trading Policy, which, among other things, prohibits directors from entering into short sales or hedging or pledging our common units and HFC common stock. The anti-hedging policy contained in our Insider Trading Policy specifically prohibits directors and their designees from purchasing financial instruments or otherwise engaging in transactions that hedge or offset or are designed to hedge or offset any decrease in the market value of HEP or HFC securities (or derivatives thereof), regardless of how the securities (or derivatives thereof) were acquired.

Eric L. Mattson	$	125,000	$	105,017	$	230,017

__________________

(1) Mr. Damiris is not included in this table because he received no additional compensation for his service on the Board since, during 2019, Mr. Damiris was an executive officer of HFC and HLS. The compensation paid by HFC to Mr. Damiris in 2019 will be shown in HFC’s 2020 Proxy Statement. A portion of the compensation paid to Mr. Damiris by HFC in 2019 is allocated to the services he performed for us in his capacity as an executive officer of HLS and is disclosed in the “Summary Compensation Table” below. Mr. Damiris retired as an officer and director of HLS and HFC effective December 31, 2019.

(2) Reflects the aggregate grant date fair value of restricted units granted to non-employee directors, computed in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 (“FASB ASC Topic 718”), determined without regard to forfeitures. See Note 9 to our consolidated financial statements for the fiscal year ended December 31, 2019, for a discussion of the assumptions used in determining the FASB ASC Topic 718 grant date fair value of these awards.

On October 23, 2019, Messrs. Baldwin, Jennings, Lee and Mattson and Ms. LaFollette received an award of 4,465 restricted units that vests on December 1, 2020, subject to continued service on the Board. On December 4, 2019, Mr. Jennings forfeited his award due to his appointment as an executive officer of HFC and HLS. As of December 31, 2019, these are the only restricted units held by our current non-employee directors. For additional information regarding the annual restricted unit grants, please refer to the “Director Compensation” narrative above.

Item 11. Executive Compensation

Compensation Discussion and Analysis

This Compensation Discussion and Analysis provides information about our compensation objectives and policies for the HLS executive officers who are our “Named Executive Officers” for 2019 to the extent the Compensation Committee or our Chief Executive Officer determines the compensation of these individuals and about the compensation for our other Named Executive Officers that is allocated to us pursuant to Compensation Committee action or SEC rules. In addition, the Compensation Discussion and Analysis is intended to place in perspective the information contained in the executive compensation tables that follow this discussion and provide a description of our policies relating to reimbursement to HFC and HLS for compensation expenses.

Overview

We are managed by HLS, the general partner of HEP Logistics, our general partner. HLS is a subsidiary of HFC. The employees providing services to us are either provided by HLS, which utilizes people employed by HFC to perform services for us, or seconded to us by subsidiaries of HFC, as we do not have any employees.

- 118 -

For 2019, our “Named Executive Officers” were:

Name	Position with HLS in 2019
George J. Damiris (1)	Chief Executive Officer and President
Richard L. Voliva III (2)	Executive Vice President and Chief Financial Officer
Mark T. Cunningham	Senior Vice President, Operations and Engineering
Vaishali S. Bhatia (3)	Senior Vice President, General Counsel, Chief Compliance Officer and Secretary

(1) Mr. Damiris retired as Chief Executive Officer and President of HLS effective December 31, 2019.

(2) Mr. Voliva was appointed as President of HLS effective January 1, 2020.

(3) Ms. Bhatia was appointed as Senior Vice President and General Counsel of HLS effective November 14, 2019. She was appointed as Chief Compliance Officer and Secretary of HLS effective August 13, 2019. She resigned as Chief Compliance Officer in January 2020.         

Certain of our Named Executive Officers are also officers of HFC or provide services to HFC. During 2019:

• Mr. Cunningham spent all of his professional time managing our business and affairs and did not provide any services to HFC.

• Messrs. Damiris and Voliva and Ms. Bhatia, who we generally refer to as the “HFC Shared Officers,” also served as executive officers of HFC and devoted as much of their professional time as was necessary to oversee the management of our business and affairs. All compensation paid to such executive officers is paid and determined by HFC, without input from the Compensation Committee.

Fees and Reimbursements for Compensation of Named Executive Officers

• Administrative Fee Covers HFC Shared Officers. Under the terms of the Omnibus Agreement we pay an annual administrative fee to HFC (currently $2.6 million) for the provision of general and administrative services for our benefit, which may be increased or decreased as permitted under the Omnibus Agreement. The administrative services covered by the Omnibus Agreement include, without limitation, the costs of corporate services provided to us by HFC such as accounting, tax, information technology, human resources, in-house legal support and office space, furnishings and equipment. None of the services covered by the administrative fee are assigned any particular value individually. Although the administrative fee covers the services provided to us by the Named Executive Officers who are HFC Shared Officers, no portion of the administrative fee is specifically allocated to services provided by those Named Executive Officers to us. Rather, the administrative fee generally covers services provided to us by HFC and, except as described below, there is no reimbursement by us for the specific costs of such services. See Item 13, “Certain Relationships and Related Transactions, and Director Independence” of this Annual Report on Form 10-K for additional discussion of our relationships and transactions with HFC.

• Reimbursements for Compensation of Dedicated HLS Officers. Under the Omnibus Agreement, we also reimburse HFC for certain expenses incurred on our behalf, such as for salaries and employee benefits for certain personnel employed by HFC who perform services for us on behalf of HLS, including the dedicated HLS officers, as described in greater detail below. The partnership agreement provides that our general partner will determine the expenses that are allocable to us. In 2019, we reimbursed HFC for 100% of the compensation expenses incurred by HFC for salary, bonus, retirement and other benefits provided to Mr. Cunningham. With respect to equity compensation paid by us to Mr. Cunningham, HLS purchases the units delivered pursuant to awards under our Long-Term Incentive Plan, and we reimburse HLS for the purchase price of the units.

Compensation Decisions for Dedicated HLS Officers

• Generally. The Compensation Committee, pursuant to its charter, determines cash and bonus compensation only for HLS’s Chief Executive Officer, President or Chief Financial Officer if such officers are solely dedicated to HLS and are not HFC Shared Officers. During 2019, HLS’s Chief Executive Officer, President and Chief Financial Officer were HFC Shared Officers, and as a result, the Compensation Committee did not set cash and bonus compensation for any executive officer. For 2019, the Compensation Committee made compensation decisions for Mr. Cunningham only with respect to long-term equity incentive awards. All other compensation provided to Mr. Cunningham, other than with respect to

- 119 -

pension and retirement benefits as described below, for 2019 was determined by the Chief Executive Officer of HLS and is reported, in accordance with SEC rules, in the tables that follow.

• Pension and Retirement Benefits. The Compensation Committee does not review or approve pension or retirement benefits for any of the Named Executive Officers. Rather, all pension and retirement benefits provided to the executives are the same pension and retirement benefits that are provided to employees of HFC generally, and such benefits are sponsored and administered entirely by HFC without input from HLS or the Compensation Committee. The pension and retirement benefits provided to Mr. Cunningham in 2019 are described below and were charged to us monthly in accordance with the Omnibus Agreement.

Allocation of Compensation and Compensation Decisions for HFC Shared Officers

• Generally. HFC makes all decisions regarding the compensation paid to the HFC Shared Officers, which compensation is covered by the administrative fee under the Omnibus Agreement (and therefore not subject to reimbursement by us); however, in accordance with SEC rules, for purposes of these disclosures, a portion of the compensation paid by HFC to the HFC Shared Officers for 2019 is allocated to the services they performed for us during 2019. The allocation was made based on the assumption that each of Messrs. Damiris and Voliva and Ms. Bhatia spent, in the aggregate, the following percentage of his or her professional time on our business and affairs in 2019:

Name	Percentage of Time
George J. Damiris	20%
Richard L. Voliva III	20%
Vaishali S. Bhatia	25%

Because HFC made all decisions regarding the compensation paid to Messrs. Damiris and Voliva and Ms. Bhatia for 2019, those decisions are not discussed in this Compensation Discussion and Analysis. The total compensation paid by HFC to Messrs. Damiris and Voliva in 2019 will be disclosed in HFC’s 2020 Proxy Statement. The compensation paid by HFC to Ms. Bhatia is discussed and disclosed in the tables that follow.

Objectives of Compensation Program

Our compensation program is designed to attract and retain talented and productive executives who are motivated to protect and enhance our long-term value for the benefit of our unitholders. Our objective is to be competitive with our industry and encourage high levels of performance from our executives.

In supporting our objectives, in applicable years, the Compensation Committee considers the cash compensation to be received by the dedicated HLS officers when determining equity compensation for the dedicated HLS officers; however, the Compensation Committee has not adopted any formal policies for allocating compensation among salary, bonus and long-term equity compensation.

In the fourth quarter of 2018, the Compensation Committee, with the assistance of the Chief Executive Officer, reviewed the mix and level of cash and long-term equity incentive compensation for Mr. Cunningham with a goal of providing competitive compensation for 2019 to retain him, while at the same time providing him incentives to maximize long-term value for us and our unitholders.

Role of the Compensation Consultant and the Compensation Committee in the Compensation Setting Process

Since 2018, the Compensation Committee has retained Meridian, a consulting firm specializing in executive compensation, to advise the Compensation Committee on matters related to executive and non-employee director compensation and long-term equity incentive awards. The Compensation Consultant provided the Compensation Committee with market data, updates on related trends and developments, advice on program design, and input on compensation decisions for executive officers and non-employee directors. As discussed above under “The Board, Its Committees and Director Compensation–Board Committees–Compensation Committee,” the Compensation Committee has concluded that we do not have any conflicts of interest with Meridian.

The Compensation Committee generally makes compensation decisions for a given fiscal year in the fourth quarter of the prior year. The Compensation Consultant does not have authority to determine the ultimate compensation paid to executive officers or

- 120 -

non-employee directors, and the Compensation Committee is under no obligation to utilize the information provided by the Compensation Consultant when making compensation decisions. The Compensation Consultant provides external context and other input to the Compensation Committee prior to the Compensation Committee approving salaries and fees, awarding bonuses and equity compensation or establishing awards for the upcoming year. Meridian provided information and advice to the Compensation Committee in 2018 with respect to matters related to executive and non-management director compensation for 2019.

Beginning with 2019 compensation, the Compensation Committee, pursuant to its charter, will determine cash and annual incentive compensation for only HLS’s Chief Executive Officer, President or Chief Financial Officer, if such officers are solely dedicated to HLS and are not HFC Shared Officers. For all other dedicated HLS Officers, the Compensation Committee will only determine long-term equity incentive compensation.

Review of Market Data

Market pay levels are one of many factors considered by the Compensation Committee in setting equity compensation for the Named Executive Officers. In 2018, the Compensation Committee reviewed comparison data provided by the Compensation Consultant with respect to annual incentive levels and long-term incentive levels as one point of reference in evaluating the reasonableness and competitiveness of the incentive compensation paid to our executive officers as compared to companies with which we compete for executive talent. In addition, the Compensation Committee reviewed such data to evaluate whether our incentive compensation reflects practices of comparable companies of generally similar size and scope of operations. The Compensation Consultant obtained market information primarily from SEC filings of publicly traded companies that the Compensation Consultant and the Compensation Committee consider appropriate peer group companies and, from time to time, from published compensation surveys (such as the Liquid Pipeline Roundtable Compensation Survey). The purpose of the peer group is to provide a frame of reference with respect to executive equity compensation at companies of generally comparable size and scope of operations, rather than to set specific benchmarks for the compensation provided to the Named Executive Officers. We select peer group companies that we believe provide relevant data points for our consideration.

The peer group used in determining 2019 equity compensation included the following companies, which are representative of the companies with which we compete for talent:

American Midstream Partners, LP	Enable Midstream Partners, LP
Andeavor Logistics LP	Enbridge Energy Partners, L.P.
Archrock Partners, L.P.	EnLink Midstream Partners, LP
Black Stone Minerals, L.P.	Extraction Oil & Gas, Inc.
Boardwalk Pipeline Partners, LP	Phillips 66 Partners LP
Buckeye Partners, L.P.	SemGroup Corporation
Callon Petroleum Company	Shell Midstream Partners, L.P.
Carrizo Oil & Gas, Inc.	Summit Midstream Partners, LP
Centennial Resource Development, Inc.	TC Pipelines, LP
Crestwood Equity Partners LP	Valero Energy Partners LP

The peer group used for 2019 compensation was changed from the peer group used with respect to 2018 compensation due to merger activity and recommendations from the Compensation Consultant..

For years in which we make the compensation decisions for our executive officers, our objective generally is to position pay at levels approximately in the middle range of market practice, taking into account median levels derived from our peer group analysis. Following advice from the Compensation Consultant, we consider our salary and non-salary compensation components relative to the median compensation levels generally within the peer group rather than to an exact percentile above or below the median. For these purposes, if compensation is generally within plus or minus 20% of the market median, it is considered to be in the middle range of the market. As noted, however, this market analysis is just one of many factors considered when making overall compensation decisions for our executives.

Role of Named Executive Officers in Determining Executive Compensation

In making executive equity compensation decisions for 2019, the Compensation Committee reviewed the total compensation provided to each executive in the prior year, the executive’s overall performance and market data provided by the Compensation

- 121 -

Consultant. The Compensation Committee also considered recommendations by the Chief Executive Officer and other factors in determining the appropriate final equity compensation amounts.

Various members of management facilitated the Compensation Committee’s consideration of equity compensation for Named Executive Officers by providing data for the Compensation Committee’s review. This data includes, but is not limited to, performance evaluations, performance-based compensation provided to the Named Executive Officers in previous years, tax-related considerations and accounting-related considerations. Given the day-to-day familiarity that management has with the work performed, the Compensation Committee values management’s recommendations, although no Named Executive Officer has authority to determine or comment on compensation decisions directly related to himself or herself. As described above, the Compensation Committee made the final decision only as to the long-term equity compensation of Mr. Cunningham.

In the fourth quarter of 2019, the Chief Executive Officer reviewed information similar to that provided to the Compensation Committee for purposes of determining salary and bonus compensation for Mr. Cunningham. The Chief Executive Officer sets compensation for his direct reports who are solely dedicated to HLS and who do not serve as President or Chief Financial Officer of HLS.

Overview of 2019 Executive Compensation Components and Decisions

The components of compensation received by Mr. Cunningham in 2019 are as follows:

• base salary;

• annual incentive cash bonus compensation;

• long-term equity incentive compensation;

• severance and change in control benefits;

• health and retirement benefits; and

• perquisites.

Each of these components is described in further detail in the narratives and/or tables that follow.

Base Salary

Base salary for Mr. Cunningham for 2019 was determined by the Chief Executive Officer of HLS in the fourth quarter of 2018. The Chief Executive Officer considered Mr. Cunningham’s position, level of responsibility and performance in 2018. The Chief Executive Officer also reviewed competitive market data relevant to his position. Following a review of the various factors listed above, Mr. Cunningham’s 2019 base salary was $322,233, which was effective January 1, 2019 and which represented a 3.3% increase from Mr. Cunningham’s 2018 base salary of $312,090.

Annual Incentive Cash Bonus Compensation

Target awards and performance metrics for the 2019 annual incentive plan for Mr. Cunningham were determined by the Chief Executive Officer of HLS in the fourth quarter of 2018.

The following table sets forth the minimum, target and maximum award opportunities (as a percentage of annual base salary) for Mr. Cunningham for 2019, and the portion of Mr. Cunningham’s target award opportunity that is allocated to each performance measure (as a percentage of his annual base salary).

	Award Opportunities			Allocation Among Performance Measures (as a percentage of annual base salary)
Name	Minimum	Target	Maximum	Financial Measures	Operational Measures	Strategic and Individual Measures
Mark T. Cunningham	22.5%	45.0%	90.0%	18%	18%	9%

The financial measures are weighted equally with the operational measures. Awards are capped to avoid encouraging an excessive short-term focus, potentially at the expense of long-term performance.

- 122 -

To facilitate timely determination of award payouts, the measurement period for each of the above metrics covers four consecutive quarters starting with the fourth quarter of the preceding year (2018) and ending with the third quarter of the following year (2019).

These awards were subject to our achievement of specified levels of performance with respect to financial, operational and strategic and individual performance measures. The following table sets forth the various components for each measure.

Performance Measure (percentage of the annual bonus awards)	Components (percentage of each performance measure)	How It’s Measured (percentage of each component)
Financial (40%)	EBITDA	Cumulative EBITDA performance of HEP vs. Cumulative Target for HEP
Operational (40%)	• Environmental, Health and Safety (40%)(1) • Reliability (40%) (2) • Operating Expense vs. Budget (20%) (3)	• Recordable Injury Rate • Lost Time Injuries • Vehicle Incidents • Employee Based Environmental Releases • Solomon Liquid Pipeline Availability
Strategic and Individual (20%)	Relevant individual metrics for each named executive officer	Mark T. Cunningham  • Safety and environmental  • Maintenance capital and XO expense management  • Asset reliability  • Growth projects  • Pipeline excellence and communication

(1) The EHS metric is divided into the following four equally weighted measures:

• Recordable Injury Rate, which is based on the number of employees out of 100 that have been involved in a recordable event.

• Lost Time Injury, which is based on the number of injuries causing an employee to miss work.

• Vehicle Incidents, which is based on the number of incidents generating greater than $5,000 of property damage per 1,000,000 miles driven by HEP employees.

• Employee Based Environmental Releases, which is based on loss of containment caused by an employee that is reportable to either a state or federal agency.

(2) The reliability metric is based on the weighted average Solomon Liquid Pipeline Availability.

(3) Operating Expense includes all direct and controllable cash operating costs, which includes Selling, General and Administrative (SG&A) costs. Budgeted costs exclude asset write-downs, impairments, inventory valuation charges, unbudgeted litigation and legal settlement costs, environmental charges resulting from events which occurred prior to the beginning of the performance period, variable energy and utility costs, and unbudgeted bonus expenses and costs related to unbudgeted new capital assets brought online and acquisitions made during the period. The metric is based on the actual cash operating expense of each segment versus the budgeted cash operating expense for each segment.

Financial Measures

The table below sets forth the threshold, target and maximum performance levels for each financial measure and the actual results for the financial measures in 2019:

Metric	Threshold (50%)	Target (100%)	Maximum (200%)	Actual for 2019	Percent of Target Bonus Achievement
EBITDA (in millions)	$343,000	$361,000	$379,000	$366,000	128	%

Operational Measures

The table below sets forth the threshold, target and maximum performance levels for each operational measures and the actual results for the operational measures in 2019:

Metric	Threshold (50%)	Target (100%)	Maximum (250%)	Actual for 2019	Percent of Target Bonus Achievement
EH&S					99%
Recordable Injury Rate	1.0	0.80	0	1.64	0%
Lost Time Injuries	2	1	0	3	0%
Vehicle Incidents	1.8	1.4	0	1.02	195%
Employee Based Environmental Releases	3	2	0	1	200%

______________________

Payouts are interpolated between threshold and target and target and maximum, except that for the recordable injury rate, a rate of .60 equates to a 200% payout, for vehicle incidents, 1.0 incidents equates to a 200% payout, and for employee based environmental releases, 1 release equates to a 200% payout.

Metric	Threshold (50%)	Target (100%)	Maximum (200%)	Actual for 2019	Percent of Target Bonus Achievement
Reliability	98.0% Available	98.75% Available	≥ 99.5% Available	99.79	200%
Operating Expense	5% over Budget	Budget	5% or more under Budget	2% over Budget	79%

_________________________

Payouts are interpolated between threshold and target and target and maximum.

The total percent of target bonus achieved for the operational measures was 135.3%.

Strategic and Individual Performance Measures

In addition to the measures mentioned above, a portion of the award for Mr. Cunningham was based on the Chief Executive Officer’s evaluation of Mr. Cunningham’s strategic and individual performance during the year.

Long-Term Equity Incentive Compensation

The Long-Term Incentive Plan was adopted by the Board in August 2004 with the objective of:

• promoting our interests by providing equity incentive compensation awards to eligible individuals;

- 124 -

• enhancing our ability to attract and retain the services of individuals who are essential for our growth and profitability;

• encouraging those individuals to devote their best efforts to advancing our business; and

• aligning the interests of those individuals with the interests of our unitholders.

The Compensation Committee (and beginning in 2018, the Board) typically grants long-term equity incentive awards to dedicated HLS officers on an annual basis. Annual long-term equity incentive award grants are made in the fourth quarter of the year preceding the year to which the award relates, in order to align the timing of the long-term equity incentive award grants with the timing of the other compensation decisions made for the dedicated HLS officers. As a result, annual long-term equity incentive awards for the 2019 year were granted in November 2018 to the individuals who were dedicated HLS officers at that time. Pursuant to SEC rules, the long-term equity incentive awards granted in November 2018 for the 2019 year are disclosed as 2018 compensation in the Summary Compensation Table (with respect to those Named Executive Officers who received long-term equity incentive awards from us in November 2018) and are not included in the 2019 Grants of Plan-Based Awards table; however, because these awards relate to the 2019 year, they are described in greater detail below.

In determining the appropriate amount and type of long-term equity incentive awards to be granted each year, the Compensation Committee (and beginning in 2018, the Board) considers the executive’s position, scope of responsibility, base salary and available compensation information for executives in comparable positions in similar companies. Our goal is to reward the creation of value and strong performance with variable compensation dependent on that performance.

For the 2019 year, the Board awarded both phantom units and performance units to Mr. Cunningham. Due to SEC rules regarding the timing of disclosures, Mr. Cunningham’s awards with respect to the 2019 year are reflected in the Executive Compensation Tables below as awards granted in the 2018 year. The awards that are reflected in the Executive Compensation Tables during the 2019 year are awards that were granted in late 2019 with respect to the 2020 year, described in further detail below. It is our practice not to make long-term equity incentive award grants to the HFC Shared Officers. Any equity compensation awards granted by HFC for 2019 to any of the HFC Shared Officers will be disclosed in HFC’s 2020 Proxy Statement to the extent such individuals are “named executive officers” of HFC for the 2019 year.

Phantom Unit Awards

In November 2018, Mr. Cunningham was granted phantom units. The number of phantom units awarded was initially recommended by the Compensation Committee, and approved by the Board, in dollar amounts established according to the pay grade of the executive officer. The award is then converted to a number of units by dividing the targeted dollar amount by the closing price of our common units on the grant date of the award. The following table sets forth the number of phantom units awarded to Mr. Cunningham in November 2018 for the 2019 year:

Name	Number of Phantom Units
Mark T. Cunningham	5,220

Phantom unitholders have the right to receive distribution equivalents and other distributions paid with respect to such phantom units, and these distribution equivalents are paid at approximately the same time as distributions are paid on our common units. The distribution equivalents are not subject to forfeiture.

The phantom units granted in November 2018 were originally scheduled to vest in three equal annual installments to be fully vested and nonforfeitable after December 15, 2021. In February 2019, we determined that all outstanding equity awards with a vesting date of December 15 would be changed to a vesting date of December 1 of the applicable year. This vesting date change was deemed to be a minor administrative modification necessitated by our growth and the number of existing award holders. Therefore, the November 2018 phantom units vest in three equal annual installments according to the schedule below, subject to continued employment by the unitholder.

- 125 -

Phantom Unit Vesting Criteria
Vesting Date (1)	Cumulative Amount of Phantom Units Vested
Immediately following December 1, 2019	1/3
Immediately following December 1, 2020	2/3
Immediately following December 1, 2021	All

(1) Vesting will occur on the first business day following the vesting date set forth above if the vesting date falls on a Saturday or a Sunday. The provisions affecting the vesting of these awards upon a change in control or certain terminations of employment are described in greater detail below in the section titled “Potential Payments upon Termination and Change in Control.”

Performance Unit Awards

A performance unit is a notational phantom unit that entitles the grantee to receive a common unit upon the attainment of pre-established performance targets over a specified performance period, which may include the achievement of specified financial objectives determined by the Compensation Committee (and beginning in 2018, the Board), and satisfaction of certain continued service conditions.

In November 2018, Mr. Cunningham was granted performance units with a performance period that began on January 1, 2019 and ends on December 31, 2021. An executive officer generally must remain employed through the end of the performance period to be eligible to earn any of the performance units. The provisions affecting the vesting of these awards upon a change in control or certain terminations of employment are described below in the section titled “Potential Payments upon Termination and Change in Control.”

With respect to the performance unit awards for the 2019 year, Mr. Cunningham was granted a target number of performance units. The target number was initially recommended by the Compensation Committee, and approved by the Board, in dollar amounts established according to the pay grade of the executive officer. The target award is then converted to a number of units by dividing the targeted dollar amount by the closing price of our common units on the grant date of the award. The following table sets forth the target number of performance units granted to Mr. Cunningham in November 2018 for the 2019 year:

Name	Target Number of Performance Units
Mark T. Cunningham	5,220

The Board determined that performance metrics for the November 2018 grants would consist of (a) actual EBITDA compared to target EBITDA and (b) total unitholder return during the performance period as measured against that of the following incentive peer group:

Archrock Partners, L.P.	PBF Logistics LP
Buckeye Partners, L.P.	Philips 66 Partners LP
Crestwood Equity Partners LP	SemGroup Corporation
Delek Logistics Partners, LP	Shell Midstream Partners, L.P.
Enable Midstream Partners, LP	Summit Midstream Partners, LP
EnLink Midstream Partners, LP	TC Pipelines, LP
MPLX LP

For the performance unit awards granted in November 2018 for the 2019 fiscal year:

• “EBITDA,” which determines 50% of the shares earned at the end of the performance period, is defined as our earnings before interest, taxes, depreciation and amortization for each calendar year during the performance period. The Board believes EBITDA is an appropriate metric because it measures HEP’s profitability before the effects of items such as financings, capital expenditures and taxes.

• “total unitholder return,” which determines 50% of the shares earned at the end of the performance period, is defined as (a) the appreciation in our unit price during the performance period (in dollars) plus cumulative distributions paid during the

- 126 -

performance period plus any additional value or compensation received by unitholders such as units received from spinoffs, divided by (b) the closing price of our common units on the first business day of the performance period. The Compensation Committee believes total unitholder return is an appropriate metric because it (i) aligns the interests of management with the interests of unitholders and (ii) provides a useful means of comparing our overall performance relative to the overall performance of our incentive peer group.

The actual number of performance units earned at the end of the performance period will be equal to (a) the target number of performance units granted multiplied by (b) our average performance unit payout with respect to the performance metrics. The average performance unit payout is determined by adding our performance unit payout percentage with respect to each performance metric and dividing the sum by two.

For the EBITDA metric, actual aggregate EBITDA achieved during the performance period is compared to the aggregate Target EBITDA during the performance period and payout is determined in accordance with the following table:

EBITDA Achievement Relative to Target EBITDA	EBITDA Performance Percentage
Target EBITDA plus 2.5%	Maximum (200% of Target)
< Target EBITDA plus 2.5% but > Target EBITDA	Interpolate between 100% and 200%
Target EBITDA	Target (100%)
<Target EBITDA but > Target EBITDA minus 5%	Interpolate between 50% and 100%
Target EBITDA minus 5%	50% of Target (Minimum)
< Target EBITDA minus 5%	Zero

“Target EBITDA” is defined as the sum of the EBITDA targets established by the Compensation Committee for each calendar year during the performance period. Target EBITDA is communicated to the performance unit holder within the first quarter of each calendar year within the performance period.

For the total unitholder return metric, a percentile ranking of our total unitholder return versus the total unitholder return of each entity in our incentive peer group will be calculated at the end of the performance period and payout is determined in accordance with the following table:

Ranking of the Partnership within Peer Group	Total Unitholder Return Performance Percentage
>90th percentile	Maximum (200% of Target)
<90th percentile but > 50th percentile	Interpolate between 100% and 200%
50th percentile	Target (100%)
<50th percentile but > 25th percentile	Interpolate between 25% and 100%
25th percentile	25% of Target (Minimum)
<25th percentile	Zero

Earned performance share awards will be paid in the form of fully vested common units. Prior to vesting, distributions are paid on each outstanding performance unit, based on the target number of performance units subject to the award, at the same rate as distributions paid on our common units. The distributions are not subject to forfeiture.

Acquisition of Common Units for Long-Term Incentive Plan Awards

Common units delivered in connection with long-term equity incentive awards may be common units acquired by HLS on the open market, common units already owned by HLS, common units acquired by HLS directly from us or any other person or any combination of the foregoing. We currently do not hold treasury units. HLS is entitled to reimbursement by us for the cost of acquiring the common units utilized for the grant or settlement of long-term equity incentive awards.

Retirement and Other Benefits

Our Named Executive Officers participate in certain retirement plans sponsored and maintained by HFC. The cost of retirement benefits for dedicated HLS officers is charged monthly to us in accordance with the terms of the Omnibus Agreement. The terms of these benefit arrangements are described below.

- 127 -

Defined Contribution Plan

For 2019, Mr. Cunningham was eligible to participate in the HollyFrontier Corporation 401(k) Retirement Savings Plan, a tax qualified defined contribution plan (the “401(k) Plan”). Employees who are not eligible to participate in the NQDC Plan may contribute amounts between 0% and 75% of their eligible compensation to the 401(k) Plan, while employees who participate in the NQDC Plan may contribute amounts between 0% and 50% of their eligible compensation to the 401(k) Plan. Employee contributions that were made on a tax-deferred basis were generally limited to $19,000 for 2019, with employees 50 years of age or over able to make additional tax-deferred contributions of $6,000.

For 2019, all employees received an employer retirement contribution to the 401(k) Plan of 3% to 8% of the participating employee’s eligible compensation under the 401(k) Plan, subject to applicable Internal Revenue Code limitations, based on years of service, as follows:

Years of Service	Retirement Contribution (as percentage of eligible compensation)
Less than 5 years	3%
5 to 10 years	4%
10 to 15 years	5.25%
15 to 20 years	6.5%
20 years and over	8%

In addition to the retirement contribution, in 2019, employees received employer matching contributions to the 401(k) Plan equal to 100% of the first 6% of the employee’s eligible compensation contributed to the 401(k) plan up to compensation limits. Matching contributions vest immediately, and retirement contributions are subject to a three-year cliff-vesting period.

The 401(k) Plan benefits for Mr. Cunningham were charged to us in 2019 pursuant to the Omnibus Agreement.

Deferred Compensation Plan

In 2019, Mr. Cunningham was eligible to participate in the NQDC Plan. The NQDC Plan provides certain management and other highly compensated employees an opportunity to defer compensation in excess of qualified retirement plan limitations on a pre-tax basis and accumulate tax-deferred earnings to achieve their financial goals.

Participants in the NQDC Plan can contribute between 1% and 50% of their eligible earnings, which includes base salary and bonuses, to the NQDC Plan. Participants in the NQDC Plan may also receive certain employer-provided contributions, including, for 2019, matching restoration contributions, retirement restoration contributions, and nonqualified nonelective contributions. Matching restoration contributions and retirement restoration contributions represent contribution amounts that could not be made under the 401(k) Plan due to Internal Revenue Code limitations on tax-qualified plans. In 2019 (and prior years) participants in the NQDC Plan were required to contribute the maximum contribution allowed under the 401(k) Plan before deferrals would be permitted in the NQDC Plan. On and after January 1, 2020, participants in the NQDC Plan are entitled to make independent deferral elections to the NQDC Plan and the 401(k) Plan prior to meeting the contribution limitations under the 401(k) Plan. See the narrative preceding the “Nonqualified Deferred Compensation Table” for additional information regarding these contributions and the other terms and conditions of the NQDC Plan.

The NQDC Plan benefits for Mr. Cunningham were charged to us in 2019 pursuant to the Omnibus Agreement.

Other Benefits and Perquisites

Our Named Executive Officers are eligible to participate in the same health and welfare benefit plans, including medical, dental, life insurance, and disability programs sponsored and maintained by HFC, that are generally made available to all full-time employees of HFC. Health and welfare benefits for Mr. Cunningham were charged to us in 2019 pursuant to the Omnibus Agreement.

It is the Compensation Committee’s policy to provide only limited perquisites to our Named Executive Officers. We provided a reserved parking space for Mr. Cunningham in 2019. In addition, we may also reimburse our executive officers for limited

- 128 -

entertainment expenses that we deem to serve a business purpose and provide personal benefits to our executive officers in limited circumstances associated with executive team-building and strategy planning events.

Change in Control Agreements

Neither we nor HLS has entered into any employment agreements with any of the Named Executive Officers. On February 14, 2011, the Board adopted the Holly Energy Partners, L.P. Change in Control Policy (the “Change in Control Policy”) and the related form of Change in Control Agreement for certain officers of HLS (each, a “Change in Control Agreement”). The Change in Control Agreements contain “double-trigger” payment provisions that require not only a change in control of HFC, HLS or HEP, but also a qualifying termination of the executive’s employment within a specified period of time following the change in control in order for an officer to be entitled to benefits. We believe the Change in Control Agreements provide for management continuity in the event of a change in control and provide competitive benefits for the recruitment and retention of executives.

We entered into a Change in Control Agreement with Mr. Voliva, effective as of April 28, 2014, and Mr. Cunningham, effective as of February 14, 2011, in accordance with the Change in Control Policy. The Change in Control Agreement with Mr. Voliva was terminated effective October 31, 2016 when Mr. Voliva entered into a Change in Control Agreement with HFC. The material terms and the quantification of the potential amounts payable under the Change in Control Agreement in effect with Mr. Cunningham in 2019 are described below in the section titled “Potential Payments upon Termination or Change in Control.” We bear all costs and expenses associated with this agreement.

HFC has entered into Change in Control Agreements with Messrs. Damiris and Voliva and Ms. Bhatia, which were in effect during 2019 and the costs of which are fully borne by HFC (the “HFC Change in Control Agreements”). Mr. Damiris’s Change in Control Agreement with HFC terminated upon his retirement effective December 31, 2019. Payments and benefits under the HFC Change in Control Agreements are triggered only upon a change in control of HFC. The material terms, and the qualification, of the potential amounts payable under the HFC Change in Control Agreement with Mr. Voliva will be described in HFC’s 2020 Proxy Statement. Mr. Damiris entered into a Retirement Agreement with HFC in connection with his retirement, which is also described within HFC’s 2020 Proxy Statement.

Unit Ownership and Retention Policy for Executives

The Board, the Compensation Committee and our executive officers recognize that ownership of our common units is an effective means by which to align the interests of our officers with those of our unitholders. The dedicated HLS officers are subject to the HEP unit ownership and retention policy. The unit retention requirement for Mr. Cunningham is as follows:

Executive Officer	Value of Units
Mark T. Cunningham	1x Base Salary

Each covered officer is required to meet the applicable requirements within five years of first being subject to the policy. Officers are required to continuously own sufficient units to meet the unit ownership and retention requirements once attained. Until the officers attain compliance with the unit ownership and retention policy, the officers will be required to hold 25% of the units received from any equity award, net of any units used to pay the exercise price or tax withholdings. If an officer attains compliance with the unit ownership and retention policy and subsequently falls below the requirement because of a decrease in the price of our common units, the officer will be deemed in compliance provided that the officer retains the units then held.

As of December 31, 2019, Mr. Cunningham was in compliance with the unit ownership and retention policy.

Anti-Hedging and Anti-Pledging Policy

- 129 -

All of our employees, including our named executive officers, are subject to our Insider Trading Policy, which, among other things, prohibits employees from entering into short sales or hedging or pledging shares of our common units and HFC common stock. The anti-hedging policy contained in our Insider Trading Policy specifically prohibits employees, including our named executive officers, and their designees from purchasing financial instruments or otherwise engaging in transactions that hedge or offset or are designed to hedge or offset any decrease in the market value of HEP or HFC securities (or derivatives thereof), regardless of how the securities (or derivatives thereof) were acquired.

Tax and Accounting Implications

We account for equity compensation expenses under the rules of FASB ASC Topic 718, which requires us to estimate and record an expense for each award of equity compensation over the vesting period of the award. Accounting rules also require us to record cash compensation as an expense at the time the obligation is accrued. The Compensation Committee has taken into account the tax implications to us in its decision to grant long-term equity incentive compensation awards in the form of phantom units and performance units as opposed to options or unit appreciation rights.

Recoupment of Compensation

In October 2018, the Board adopted a formal clawback policy, which provides that upon occurrence of a material restatement of our financial results (other than due to a change in accounting policy or applicable law), the Board may recover bonus and other incentive and equity based compensation (the “Incentive Compensation”) awarded to Board appointed officers of HLS and our subsidiaries that were paid or awarded during the 24-month period preceding the restatement. In the event of such material restatement, if the Incentive Compensation would have been lower had it been calculated based on such restated results, the Compensation Committee may (as determined in its sole discretion and to the extent permitted by governing law and as appropriate under the circumstances), seek to recover for our benefit all or a portion of such Incentive Compensation awarded to any covered employee who is then currently employed by us. In determining whether to seek recovery, the Compensation Committee may take into account any considerations as it deems appropriate, including whether the error was caused by intentional misconduct or fraud. The amount of any recovery and the source of such recovery (whether from unvested equity compensation or future compensation payable to the covered employee) will be determined in the sole discretion of the Compensation Committee.

Additionally, equity awards granted to Named Executive Officers are subject to the terms of the Long-Term Incentive Plan, which states that such awards may be cancelled, repurchased and/or recouped to the extent required by applicable law or any clawback policy that we adopt. In addition, the award agreements for our outstanding long-term incentive compensation awards state that the award and amounts paid or realized with respect to the award may be subject to reduction, cancellation, forfeiture or recoupment to the extent required by applicable law or any clawback policy that we adopt.

2020 Compensation Decisions

Long-Term Equity Incentive Compensation

In October 2019, the Board approved annual grants of phantom units and performance units for Mr. Cunningham. Pursuant to SEC rules, the long-term equity incentive awards granted in October 2019 for the 2020 year are disclosed as 2019 compensation in the Summary Compensation Table and are reported in the 2019 Grants of Plan-Based Awards table below. These awards are also described in greater detail in the narrative that follows.

Phantom Unit Awards

In October 2019, Mr. Cunningham was granted phantom units. The number of phantom units awarded to Mr. Cunningham was determined in the same manner as the November 2018 phantom unit awards described above. The award is then converted to a number of units by dividing the targeted dollar amount by the closing price of our common units on the grant date of the award. The following table sets forth the number of phantom units awarded to Mr. Cunningham in October 2019 for the 2020 year:

Name	Number of Phantom Units
Mark T. Cunningham	6,378

Phantom unitholders have the right to receive distribution equivalents and other distributions paid with respect to such phantom units, and these distribution equivalents are paid at approximately the same time as distributions are paid on our common units. The distribution equivalents are not subject to forfeiture.

- 130 -

The phantom units granted in October 2019 to Mr. Cunningham vest in three equal annual installments to be fully vested and nonforfeitable after December 1, 2022, as follows:

Phantom Unit Vesting Criteria
Vesting Date (1)	Cumulative Amount of Phantom Units Vested
Immediately following December 1, 2020	1/3
Immediately following December 1, 2021	2/3
Immediately following December 1, 2022	All

(1) Vesting will occur on the first business day following December 1 if December 1 falls on a Saturday or a Sunday. The provisions affecting the vesting of these awards upon a change in control or certain terminations of employment are described in greater detail below in the section titled “Potential Payments upon Termination and Change in Control.”

Performance Unit Awards

In October 2019, Mr. Cunningham was granted performance units with a performance period that began on October 1, 2019 and ends on September 30, 2022. The target number of performance units awarded to Mr. Cunningham was determined in the same manner as the November 2018 performance unit awards described above. The following table sets forth the target number of performance units granted to Mr. Cunningham in November 2019 for the 2020 year:

Name	Target Number of Performance Units
Mark T. Cunningham	6,378

The Board determined that performance metrics for the October 2019 grants would consist of (a) actual EBITDA compared to target EBITDA and (b) total unitholder return during the performance period as measured against that of the following incentive peer group:

Archrock Partners, L.P.	PBF Logistics LP
Buckeye Partners, L.P.	Philips 66 Partners LP
Crestwood Equity Partners LP	SemGroup Corporation
Delek Logistics Partners, LP	Shell Midstream Partners, L.P.
Enable Midstream Partners, LP	Summit Midstream Partners, LP
EnLink Midstream Partners, LP	TC Pipelines, LP
MPLX LP

For the performance unit awards granted in October 2019 for the 2020 fiscal year, “EBITDA” for each 12 month period and “total unitholder return” are calculated in the same manner as they are calculated for the performance units granted in November 2018 for the 2019 fiscal year.

The actual number of performance units earned at the end of the performance period will be determined in the same manner as the performance units granted in November 2018 for the 2019 fiscal year.

For the EBITDA metric, actual aggregate EBITDA achieved during the performance period is compared to the aggregate Target EBITDA during the performance period and payout is determined in accordance with the following table:

- 131 -

EBITDA Achievement Relative to Target EBITDA	EBITDA Performance Percentage
Target EBITDA plus 2.5%	Maximum (200% of Target)
< Target EBITDA plus 2.5% but > Target EBITDA	Interpolate between 100% and 200%
Target EBITDA	Target (100%)
<Target EBITDA but > Target EBITDA minus 5%	Interpolate between 50% and 100%
Target EBITDA minus 5%	50% of Target (Minimum)
< Target EBITDA minus 5%	Zero

“Target EBITDA” is defined as the sum of the EBITDA targets established by the Compensation Committee for each 12-month period during the performance period. Target EBITDA is communicated to the performance unit holder within the fourth quarter of each year within the performance period.

For the total unitholder return metric, a percentile ranking of our total unitholder return versus the total unitholder return of each entity in our incentive peer group will be calculated at the end of the performance period and payout is determined in accordance with the following table:

Ranking of the Partnership within Peer Group	Total Unitholder Return Performance Percentage
> 90th percentile	Maximum (200% of Target)
<90th percentile but > 50th percentile	Interpolate between 100% and 200%
50th percentile	Target (100%)
<50th percentile but > 25th percentile	Interpolate between 25% and 100%
25th percentile	25% of Target (Minimum)
<25th percentile	Zero

Mr. Cunningham must be employed by us on December 1, 2022 (or the first business day thereafter if such date falls on a Saturday or Sunday) to receive payment of the earned performance unit awards, except as described below in “Executive Compensation-Potential Payments Upon Termination or Change in Control.” Earned performance share awards will be paid in the form of fully vested common units. Prior to vesting, distributions are paid on each outstanding performance unit, based on the target number of performance units subject to the award, at the same rate as distributions paid on our common units. The distributions are not subject to forfeiture.

Executive Compensation

The following executive compensation tables and related information are intended to be read together with the more detailed disclosure regarding our executive compensation program presented under the caption “Compensation Discussion and Analysis.”

Summary Compensation Table

The table below summarizes the total compensation paid or earned by each of the Named Executive Officers for the years specified to the extent such compensation is allocable to us pursuant to SEC rules.

Name and Principal Position	Year	Salary		Bonus (1)		Unit Awards (2)		Non-Equity Incentive Plan Compensation (3)		All Other Compensation (4)		Total
George J. Damiris Chief Executive Officer and President (5)	2019	$	740,052	$	—	$	—	$	—	$	—	$	740,052

	2017	303,000		60,600		275,058		66,660		48,692		754,010
Vaishali S. Bhatia Senior Vice President, General Counsel, Chief Compliance Officer and Secretary (6)	2019	$	229,987	$	—	$	—	$	—	$	—	$	229,987

(1) Represents the discretionary bonus amount, if any, paid pursuant to the individual performance metric under our Annual Incentive Plan prior to the 2019 year and any other bonus paid outside our Annual Incentive Plan. Other payments made under our Annual Incentive Plan are included in the “Non-Equity Incentive Plan Compensation” column.

(2) Represents the aggregate grant date fair value of awards of restricted units or phantom units and performance units made in the year indicated computed in accordance with FASB ASC Topic 718, determined without regard to forfeitures, and does not reflect the actual value that may be recognized by the executive. See Note 9 to our consolidated financial statements for the fiscal year ended December 31, 2019 for a discussion of the assumptions used in determining the FASB ASC Topic 718 grant date fair value of these awards.

Awards for the 2018 fiscal year granted in November 2017 are reported in the “Unit Awards” column of the Summary Compensation Table for 2017, awards for the 2019 fiscal year granted in November 2018 are reported in the “Unit Awards” column of the Summary Compensation Table for 2018, and awards for the 2020 fiscal year granted in October 2019 are reported in the “Unit Awards” column of the Summary Compensation Table for 2019, in each case, in accordance with SEC rules.

The performance share units awarded in October 2019 are subject to a “market condition” (the total unitholder return (“TUR”) performance metric) and a “performance condition” (earnings before interest, taxes, depreciation and amortization (“EBITDA”) performance metric). For purposes of determining the grant date fair value of the performance share units granted in October 2019, in accordance with SEC rules and FASB ASC Topic 718, we have assumed an aggregate settlement of 104.55%, which includes a settlement of 54.55% of the TUR portion of the award and 50% of the EBITDA portion of the award. The maximum payout of the aggregate awards, however, could be up to 200%. If the EBITDA portion of the award was settled at the maximum payout level of 200% (resulting in settlement of the aggregate award in an amount equal to 154.55%), the grant date fair value of the performance share unit awards granted to Mr. Cunningham would be $231,841. See “Compensation Discussion and Analysis–2020 Compensation Decisions–Long-Term Equity Incentive Compensation– Performance Unit Awards.”

The terms of the phantom unit and performance unit awards granted in October 2019 for the 2020 fiscal year are described under “Compensation Discussion and Analysis–2020 Compensation Decisions–Long-Term Equity Incentive Compensation.”

For additional information on outstanding phantom unit and performance unit awards, see below under “Outstanding Equity Awards at Fiscal Year End.”

(3) Represents the bonus amount, if any, paid under our Annual Incentive Plan. The 2019 bonus amounts under our Annual Incentive Plan are described above in greater detail under “Compensation Discussion and Analysis–Overview of 2019 Executive Compensation Components and Decisions–Annual Incentive Cash Bonus Compensation.”

(4) For 2019, includes the compensation as described under “All Other Compensation” below.

(5) During 2019, each of these officers split his professional time between HFC and us, and all compensation paid to him for 2019 was determined and paid by HFC. In accordance with SEC rules, for purposes of these disclosures, a portion of the total compensation paid by HFC to these officers for 2019 is allocated to the services he performed for us during 2019. The allocation was made based on the assumption that each officer spent, in the aggregate, approximately the following percentage of his professional time in 2019 on our business and affairs:

Name	Percentage of Time
George J. Damiris	20%
Richard L. Voliva III	20%

As a result, only the designated percentage of the total amount of compensation each officer received from HFC for 2019 has been reported in this table, and the allocated amount has been solely attributed in the table above to his base salary. This amount represents the aggregate dollar value of total compensation paid to the officer by HFC (including base salary, non-equity incentive plan compensation, equity awards and other compensation), calculated pursuant to SEC rules, multiplied by the percentage set forth next to his name above. For Mr. Damiris, the total amount paid to him in connection with his retirement from HFC was not included in determining the allocated amount reflected in this table. The total compensation paid by HFC to Messrs. Damiris and Voliva (including the portion of their salary reported in this table and the amounts paid to Mr. Damiris in connection with his retirement), will be disclosed in HFC’s 2020 Proxy Statement.

(6) During 2019, Ms. Bhatia split her professional time between HFC and us, and all compensation paid to her for 2019 was determined and paid by HFC. In accordance with SEC rules, for purposes of these disclosures, a portion of the total compensation paid by HFC to her for 2019 is allocated to the services she performed for us during 2019. The allocation was made based on the assumption that she spent, in the aggregate, approximately 25% of her professional time in 2019 on our business and affairs.

As a result, only the designated percentage of the total amount of compensation Ms. Bhatia received from HFC for 2019 has been reported in this table, and the allocated amount has been solely attributed in the table above to her base salary and non-equity incentive plan compensation. This amount represents the aggregate dollar value of total compensation paid to her by HFC (including base salary, non-equity incentive plan compensation, equity awards and other compensation), calculated pursuant to SEC rules, multiplied by 25%. The total compensation paid by HFC to Ms. Bhatia in 2019 (including the portion of her salary reported in this table) is as follows: (i) salary of $248,968 for the entirety of 2019, (ii) a discretionary bonus of $86,577 in 2019, (iii) stock awards of $492,972, which reflects the aggregate grant date fair value of awards of restricted stock units granted by HFC to Ms. Bhatia in September 2019 (1,956 restricted stock units based on a grant date closing price of $51.16 for HFC’s common stock) and restricted stock units and performance share units granted by HFC to Ms. Bhatia in November 2019 (3,804 restricted stock units and 3,804 performance share units (at target), based on a grant date closing price of $52.59 for HFC’s common stock), calculated in accordance with FASB ASC Topic 718, (iv) $63,423 pursuant to HFC’s 2019 annual incentive cash compensation program, and (v) $27,700 in 401(k) plan matching contributions and retirement contributions in 2019 and $306 in tax reimbursements for an employee award. For additional information regarding HFC’s compensation arrangements, please refer to HFC’s 2020 Proxy Statement.

Ms. Bhatia resigned as Chief Compliance Officer in January 2020.

(1) The value of the perquisites provided by us to our Named Executive Officers in 2019 did not exceed $10,000 in the aggregate, and therefore, in accordance with SEC rules, are not included in the table above or described in this footnote.

(2) For Mr. Cunningham, represents tax payments made on the executive’s behalf with respect to imputed income for family travel on our aircraft when the executive was traveling for business purposes and the family travel was business related.

Grants of Plan-Based Awards

The following table sets forth information about plan-based awards granted to our Named Executive Officers under our equity and non-equity incentive plans during 2019. In this table, awards are abbreviated as “AICP” for the annual incentive cash awards under our Annual Incentive Plan, as “PHUA” for phantom unit awards, and as “PUA” for performance unit awards. Messrs. Damiris and Voliva and Ms. Bhatia did not receive any plan-based awards from us during 2019.

The phantom unit and performance unit grants reported below for Mr. Cunningham were granted in October 2019 for the 2020 fiscal year and are reported in this table as 2019 compensation in accordance with SEC rules. These awards are described in greater detail above under “Compensation Discussion and Analysis–2020 Compensation Decisions–Long-Term Equity Incentive Compensation.” Annual long-term equity incentive awards are made once each year in the fourth quarter of the year preceding the year to which the award relates in order to align the timing of the long-term equity incentive award grants with the timing of the other compensation decisions made for our executive officers. In accordance with SEC rules, the annual long-term equity incentive awards granted in November 2018 for the 2019 fiscal year were previously reported as 2018 compensation in the Grants of Plan-Based Awards table contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

(1) Represents the potential payouts for awards granted under our annual incentive cash compensation program, which were subject to achieving certain performance targets with respect to financial measures, operational measures and strategic and individual measures. Amounts reported (a) in the “Threshold” column reflect 50% of the named executive officer’s target award opportunity under the annual incentive cash compensation program, which, in accordance with SEC rules, is the minimum amount payable for a certain level of performance under the award, (b) in the “Target” column reflect 100% of the named executive officer’s target award opportunity under the annual incentive cash compensation program, which is the target amount payable under the award, and (c) in the “Maximum” column reflect 200% of the named executive officer’s target award opportunity under the annual incentive cash compensation program, which is the maximum amount payable under the award. If less than minimum levels of performance, as described in the “Threshold” column, are attained with respect to the financial measures, operational measures and strategic and individual measures under the annual incentive cash compensation program, then 0% of the named executive officer’s target award opportunity will be earned. The performance targets and target awards are described under “Compensation Discussion and Analysis–Overview of 2019 Executive Compensation Components and Decisions–Annual Incentive Cash Bonus Compensation.” Although these awards were granted in the fourth quarter of 2018, they represent the 2019 Annual Incentive Plan awards and any payouts with respect to these awards are reported in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table for 2019.

- 135 -

(2) Represents the potential number of performance units payable under the Long-Term Incentive Plan. Amounts reported (a) in the “Threshold” column reflect 50% of the target number of performance units awarded to the named executive officer, which, in accordance with SEC rules, is the minimum amount payable for a certain level of performance under the performance unit awards, (b) in the “Target” column reflect 100% of the target number of performance units awarded to the named executive officer, which is the target amount payable under the performance unit awards, and (c) in the “Maximum” column reflect 200% of the target number of performance units awarded to the named executive officer, which is the maximum amount payable under the performance unit awards. If less than minimum levels of performance, as described in the “Threshold” column, are attained with respect to the EBITDA and total unitholder return performance metrics applicable to the performance unit awards, then 0% of the target number of performance units awarded will be earned. The number of units paid at the end of the performance period may vary from the target amount, based on our achievement of specified performance measures. The terms of the performance unit awards granted in October 2019 for the 2020 fiscal year are described above under “Compensation Discussion and Analysis–2020 Compensation Decisions–Long-Term Equity Incentive Compensation–Performance Unit Awards.”

(3) Represents awards of phantom units. The terms of the phantom unit awards granted in October 2019 for the 2020 fiscal year are described above under “Compensation Discussion and Analysis–2020 Compensation Decisions–Long-Term Equity Incentive Compensation–Phantom Unit Awards.”

(4) Represents the grant date fair value determined pursuant to FASB ASC Topic 718, based on a closing price of our common units of $23.52 on October 23, 2019. The value of performance units granted on October 23, 2019 reflects a probable settlement percentage of 104.55%. See note 2 to the Summary Compensation Table for additional information regarding the aggregate probable settlement percentage calculation.

Outstanding Equity Awards at Fiscal Year End

The following table sets forth information regarding outstanding phantom units and performance units held by each Named Executive Officer as of December 31, 2019, including awards that were granted prior to 2019. The value of these awards was calculated based on a price of $22.15 per unit, the closing price of our common units on December 31, 2019. Messrs. Damiris and Voliva and Ms. Bhatia do not hold any outstanding equity awards under our Long-Term Incentive Plan, and the table below does not reflect any outstanding HFC equity awards held by any of our Named Executive Officers.

Under SEC rules, the number and value of performance units reported is based on the number of units payable at the end of the performance period assuming the maximum level of performance is achieved. In this table, awards are abbreviated as “PHUA” for phantom unit awards and “PUA” for performance unit awards. The provisions applicable to these awards upon certain terminations of employment or a change in control are described below in the section titled “Potential Payments upon Termination or Change in Control.”

Option Exercises and Units Vested

The following table provides information regarding the vesting in 2019 of restricted unit, phantom unit and/or performance unit awards held by the Named Executive Officers. Messrs. Damiris and Voliva and Ms. Bhatia do not currently hold any equity awards under our Long-Term Incentive Plan, nor did they have any equity awards under our Long-Term Incentive Plan that vested during 2019. The table below does not reflect any information regarding the vesting in 2019 of any HFC equity awards held by any of our Named Executive Officers. To date, we have not granted any unit options.

The value realized from the vesting of restricted unit and phantom unit awards is generally equal to the closing price of our common units on the vesting date (or, if the vesting date is not a trading day, on the trading day immediately following the vesting date, unless provided otherwise by the applicable award agreement) multiplied by the number of units acquired on vesting. The value is calculated before payment of any applicable withholding or other income taxes.

Nonqualified Deferred Compensation

In 2019, Messrs. Damiris, Voliva and Cunningham participated in the NQDC Plan. In 2019, the NQDC Plan functioned as a pour-over plan, allowing key employees to defer tax on income in excess of Internal Revenue Code limits that apply under the 401(k) Plan. For 2019, the annual deferral contribution limit under the 401(k) Plan was $19,000, and the annual compensation limit was $280,000. Deferral elections made by eligible employees under the NQDC Plan apply to the total amount of eligible earnings the employees want to contribute across both the 401(k) Plan and the NQDC Plan. In 2019 (and prior years) participants in the NQDC Plan were required to contribute the maximum contribution allowed under the 401(k) Plan before deferrals would be permitted in the NQDC Plan. On and after January 1, 2020, participants in the NQDC Plan are entitled to make independent deferral elections to the NQDC Plan and the 401(k) Plan prior to meeting the contribution limitations under the 401(k) Plan. Federal and state income taxes are generally not payable on income deferred under the NQDC Plan until funds are withdrawn.

Eligible employees may make salary deferral contributions between 1% and 50% of eligible earnings to the NQDC Plan. Eligible earnings include base pay, bonuses and overtime, but exclude extraordinary pay such as severance, accrued vacation, equity compensation and certain other items. In 2019, eligible participants were required to make catch-up contributions to the 401(k)

- 137 -

Plan before any contributions will be deposited into the NQDC Plan. For 2019, the catch-up contribution limit was $6,000. Deferral elections are irrevocable for an entire plan year and must be made prior to December 31 of the year immediately preceding the plan year. Elections will carry over to the next plan year unless changed or otherwise revoked.

Participants in the NQDC Plan are eligible to receive a matching restoration contribution with respect to their elective deferrals made up to 6% of the participant’s eligible earnings for the plan year in excess of the limits under Section 401(k) of the Internal Revenue Code. These matching restoration contributions are fully vested at all times. In addition, participants are eligible for a retirement restoration contribution ranging from 3% to 8% of the participant’s eligible earnings for the plan year in excess of the limits under Section 401(k) of the Internal Revenue Code, based on years of service, as follows:

Years of Services	Retirement Contribution (as percentage of eligible compensation)
Less than 5 years	3%
5 to 10 years	4%
10 to 15 years	5.25%
15 to 20 years	6.5%
20 years and over	8%

Retirement restoration contributions are subject to a three-year cliff vesting period and will become fully vested in the event of the participant’s death or a change in control. Participants may also receive nonqualified nonelective contributions under the NQDC Plan, which contributions may be subject to a vesting schedule determined at the time the contributions are made.

Participating employees have full discretion over how their contributions to the NQDC Plan are invested among the offered investment options, and earnings on amounts contributed to the NQDC Plan are calculated in the same manner and at the same rate as earnings on actual investments. Neither HLS nor HFC subsidizes a participant’s earnings under the NQDC Plan. During 2019, the investment options offered under the NQDC Plan were the same as the investment options available to participants in the tax-qualified 401(k) Plan. The following table lists the investment options for the NQDC Plan in 2019 with the annual rate of return for each fund:

Benefits under the NQDC Plan may be distributed upon the earliest to occur of a separation from service (subject to a six month payment delay for certain specified employees under Section 409A of the Internal Revenue Code), the participant’s death, a change in control or a specified date selected by the participant in accordance with the terms of the NQDC Plan. Benefits are distributed from the NQDC Plan in the form of a lump sum payment or, in certain circumstances if elected by the participant, in the form of annual installments for up to a five-year period.

Nonqualified Deferred Compensation Table

The NQDC Plan benefits for Mr. Cunningham were charged to us in 2019 pursuant to the Omnibus Agreement. The following table provides information regarding all contributions to, and the year-end balance of, the NQDC Plan account for Mr. Cunningham. Even though Messrs.

Name	2019	Years Prior to 2019
Mark T. Cunningham	$209,508	$798,609

Potential Payments upon Termination or Change in Control

We have a Change in Control Agreement with Mr. Cunningham and maintain the Long-Term Incentive Plan, each of which provide for severance compensation and/or accelerated vesting of equity compensation in the event of a termination of employment following a change in control or under other specified circumstances. These arrangements are summarized below.

Change in Control Agreements

HFC has entered into a Change in Control Agreement with each of Messrs. Damiris and Voliva and Ms. Bhatia. The Change in Control Agreement with Mr. Damiris terminated pursuant to its terms upon his retirement and separation from HFC, and Mr. Damiris entered into a Retirement Agreement with HFC. Payments and benefits under the HFC Change in Control Agreements are triggered only upon certain termination events in connection with a change in control of HFC. A summary of the terms of the HFC Change in Control Agreements, and a quantification of potential benefits under the HFC Change in Control Agreement with Mr. Voliva, will be disclosed in HFC’s 2020 Proxy Statement. Payments that were made or will be made to Mr. Damiris pursuant to his Retirement Agreement with HFC will also be disclosed within HFC’s 2020 Proxy Statement.

We entered into a Change in Control Agreement with Mr. Cunningham, effective as of February 14, 2011, and bear all costs and expenses associated with such agreement. We entered into a Change in Control Agreement with Mr. Voliva, effective as of April 28, 2014, which agreement was terminated on October 31, 2016 when he entered into a Change in Control Agreement with HFC. Therefore the only Change in Control Agreement that we maintained with a Named Executive Officer during 2019 was Mr. Cunningham’s agreement.

Each Change in Control Agreement under our Change in Control Policy terminates on the day prior to the three-year anniversary of its effective date, and thereafter automatically renews for successive one-year terms (on each anniversary date thereafter) unless a cancellation notice is given by us 60 days prior to the automatic extension date. The Change in Control Agreements provide that if, in connection with or within two years after a “Change in Control” of HFC, HLS, HEP Logistics or HEP (1) the executive’s employment is terminated by HFC, HLS, HEP Logistics or HEP without “Cause,” by the employee for “Good Reason,” or as a condition of the occurrence of the transaction constituting the “Change in Control,” or (2) the executive does not remain employed by HFC, HLS, HEP Logistics or HEP or any of their respective affiliates or the executive is not offered employment with HFC, HLS, HEP, HEP Logistics or any of their affiliates on substantially the same terms in the aggregate as his previous employment within 30 days after the termination, then the executive will receive the following cash severance amounts paid by us:

• an amount equal to his accrued and unpaid salary, unreimbursed expenses and accrued vacation pay; and

• a lump sum amount equal to a designated multiplier times (i) the executive’s annual base salary as of the date of termination or the date immediately prior to the “Change in Control,” whichever is greater, and (ii) the executive’s annual bonus amount, calculated as the average annual bonus paid to him for the prior three years. The severance multiplier is 1.0 for Mr. Cunningham.

The executive will also receive continued participation by the executive and his or her dependents in medical and dental benefits for the number of years equal to the executive’s designated severance multiplier, which, in the case of Mr. Cunningham, is one year.

- 140 -

For purposes of the Change in Control Agreements, a “Change in Control” occurs if:

• a person or group of persons (other than HFC or any of its wholly-owned subsidiaries; HLS, HEP, HEP Logistics or any of their subsidiaries) becomes the beneficial owner of more than 50% of the combined voting power of the then outstanding securities of HFC, HLS, HEP or HEP Logistics or more than 50% of the outstanding common stock or membership interests, as applicable of HFC or HLS;

• the individuals who as of the date of grant constituted a majority of HFC’s Board of Directors and individuals whose election by HFC’s Board of Directors, or nomination for election by the holders of the voting securities of HFC, was approved by a vote of at least two-thirds of the directors, cease for any reason to constitute a majority of HFC’s Board of Directors;

• the consummation of a merger, consolidation or recapitalization of HFC, HLS, HEP or HEP Logistics resulting in the holders of voting securities of HFC, HLS, HEP or HEP Logistics, as applicable, prior to the merger or consolidation owning less than 50% of the combined voting power of the voting securities of HFC, HLS, HEP or HEP Logistics, as applicable, or a recapitalization of HFC, HLS, HEP or HEP Logistics in which a person or group becomes the beneficial owner of securities of HFC, HLS, HEP or HEP Logistics, as applicable, representing more than 50% of the combined voting power of the then outstanding securities of HFC, HLS, HEP or HEP Logistics, as applicable;

• the holders of voting securities of HFC or HEP approve a plan of complete liquidation or dissolution of HFC or HEP, as applicable; or

• the holders of voting securities of HFC or HEP approve the sale or disposition of all or substantially all of the assets of HFC or HEP, as applicable, other than to an entity holding at least 60% of the combined voting power of the voting securities immediately prior to such sale or disposition.

For purposes of the Change in Control Agreements, “Cause” is defined as:

• the engagement in any act of willful gross negligence or willful misconduct on a matter that is not inconsequential; or

• conviction of a felony.

For purposes of the Change in Control Agreements, “Good Reason” is defined as, without the express written consent of the executive:

• a material reduction in the executive’s (or his supervisor’s) authority, duties or responsibilities;

• a material reduction in the executive’s base compensation; or

• the relocation of the executive to an office or location more than 50 miles from the location at which the executive normally performed the executive’s services, except for travel reasonably required in the performance of the executive’s responsibilities.

All payments and benefits due under the Change in Control Agreements will be conditioned on the execution and non-revocation by the executive of a release of claims for the benefit of HFC, HLS, HEP and HEP Logistics and their related entities and agents. The Change in Control Agreements also contain confidentiality provisions pursuant to which each executive agrees not to disclose or otherwise use the confidential information of HFC, HLS, HEP or HEP Logistics. Violation of the confidentiality provisions entitles HFC, HLS, HEP or HEP Logistics to complete relief, including injunctive relief. Further, in the event of a breach of the confidentiality covenants, the executive could be terminated for Cause (provided the breach constituted willful gross negligence or misconduct on the executive’s part that is not inconsequential). The agreements do not prohibit the waiver of a breach of these covenants.

If amounts payable to an executive under a Change in Control Agreement (together with any other amounts that are payable by HFC, HLS, HEP or HEP Logistics as a result of a change in ownership or control) exceed the amount allowed under Section 280G of the Internal Revenue Code for such executive by 10% or more, we will pay the executive an amount necessary to allow the executive to retain a net amount equal to the total present value of the payments on the date they are to be paid. Conversely, if the payments exceed the 280G limit for the executive by less than 10%, the payments will be reduced to the level at which no excise tax applies.

Long-Term Equity Incentive Awards

The outstanding long-term equity incentive awards granted under the Long-Term Incentive Plan to our Named Executive Officers vest upon a “Special Involuntary Termination,” which occurs when, within 60 days prior to or at any time after a “Change in Control”:

- 141 -

• the executive’s employment is terminated, other than for “Cause,” or

• the executive resigns within 90 days following an “Adverse Change.”

All outstanding performance units granted prior to 2018 will vest at 150% in the event of a Special Involuntary Termination, and performance units granted in 2018 and 2019 will vest at 200% in the event of a Special Involuntary Termination.

In the event of an executive’s death, disability or retirement, phantom units and performance units vest as follows:

• Phantom Units: Upon death or disability, the executive will vest with respect to a pro rata number of units attributable to the period of service completed during the applicable vesting period and will forfeit any unvested units. Under the phantom units granted in November 2017 and November 2018, upon “Retirement,” the executive will fully vest in all phantom units. Under the phantom units granted in October 2019, upon “Retirement,” the executive will vest with respect to a pro rata number of units attributable to the period of service completed during the applicable vesting period and will forfeit any unvested units.

• Performance Units: Pursuant to the terms of the November 2017 and November 2018 performance unit award agreements, upon "Retirement" the award will remain outstanding and eligible to vest without proration subject to actual performance. Pursuant to the terms of the October 2019 performance unit award agreements, upon “Retirement,” the executive becomes vested in a number of performance units attributable to the period of service completed during the applicable vesting period multiplied by the target number of performance units awarded and will forfeit any unvested units. Upon death or disability, the executive will remain eligible to vest with respect to a pro-rata number of units attributable to the period of service completed during the applicable performance period (rounded up to include the month of termination) and will forfeit any unvested units. The Compensation Committee will determine the number of remaining performance units earned and the amount to be paid to the executive as soon as administratively possible after the end of the performance period based upon the performance actually attained for the entire performance period (provided that executives will earn and receive payment with respect to no less than 50% of the performance units awarded prior to 2018). The foregoing also applies if the executive separates from employment for any other reason other than a voluntary separation, Special Involuntary Separation or for “Cause.”

For purposes of the long-term equity incentive awards, a “Change in Control” occurs if:

• a person or group of persons (other than HFC or any of its wholly-owned subsidiaries or HLS, HEP, HEP Logistics or any of their subsidiaries) becomes the beneficial owner of more than 40% of the combined voting power of the then outstanding securities of HFC, HLS, HEP or HEP Logistics;

• the individuals who as of the date of grant constituted a majority of HFC’s Board of Directors cease for any reason to constitute a majority of HFC’s Board of Directors;

• the consummation of a merger, consolidation or recapitalization of HFC, HLS, HEP or HEP Logistics resulting in the holders of voting securities of HFC, HLS, HEP or HEP Logistics, as applicable, prior to the merger or consolidation owning less than 60% of the combined voting power of the voting securities of HFC, HLS, HEP or HEP Logistics, as applicable, or a recapitalization of HFC, HLS, HEP, or HEP Logistics in which a person or group becomes the beneficial owner of securities of HFC, HLS, HEP or HEP Logistics, as applicable, representing more than 40% of the combined voting power of the then outstanding securities of HFC, HLS, HEP or HEP Logistics, as applicable;

• the holders of voting securities of HFC, HLS, HEP or HEP Logistics approve a plan of complete liquidation or dissolution of HFC, HLS, HEP or HEP Logistics, as applicable; or

• the holders of voting securities of HFC, HLS, HEP or HEP Logistics approve the sale or disposition of all or substantially all of the assets of HFC, HLS, HEP or HEP Logistics, as applicable, other than to an entity holding at least 60% of the combined voting power of the voting securities immediately prior to such sale or disposition.

For purposes of the phantom unit awards and the performance units, “Retirement” is defined as a termination of employment other than for Cause on or after the date on which the executive: (i) has achieved ten years of continuous service and (ii) has attained age sixty.

For purposes of the performance unit awards, “Adverse Change” is defined as, without the consent of the executive:

• a change in the executive’s principal office of employment of more than 25 miles from the executive’s work address at the time of grant of the award;

• a material increase (without adequate consideration) or material reduction in the duties to be performed by the executive; or

- 142 -

• a material reduction in the executive’s base compensation (other than bonuses and other discretionary items of compensation) that does not apply generally to employees.

For purposes of the long-term equity incentive awards, “Cause” is defined as:

• an act of dishonesty constituting a felony or serious misdemeanor and resulting (or intended to result in) gain or personal enrichment to the executive at the expense of HLS;

• gross or willful and wanton negligence in the performance of the executive’s material and substantial duties; or

• conviction of a felony involving moral turpitude.

The long-term equity incentive awards granted in 2018 and 2019 were granted to our Named Executive Officers with certain restrictive covenants that generally mirror the release requirements and confidentiality restrictions found in our Change in Control Agreements described above. The awards were also granted with non-solicitation provisions that generally prevent the Named Executive Officers from soliciting any employee or service provider of us or our affiliates for one year following a termination of employment.

Quantification of Benefits

The following table summarizes the compensation and other benefits that would have been payable to the Named Executive Officers under the arrangements described above assuming their employment terminated under various scenarios, including in connection with a change in control, on December 31, 2019. For these purposes, our common unit price was assumed to be $22.15, which was the closing price per unit on December 31, 2019.

In reviewing the table, please note the following:

• For purposes of determining amounts under the “Cash Payments” column, accrued and unpaid salary and unreimbursed expenses were assumed to equal zero.

• Accrued vacation for a specific year is not allowed to be carried over to a subsequent year, so we assumed all accrued vacation for the 2019 year was taken prior to December 31, 2019. Because we accrue vacation in any given year for the following year, amounts reported as “Cash Payments” include vacation amounts for Mr. Cunningham of $38,481.60 accrued in 2019 for the 2020 year.

• For amounts payable to the Named Executive Officers with respect to performance units upon a termination due to death, disability, retirement or other separation (other than a voluntary separation, a for “Cause” separation or a Special Involuntary Termination), we assumed the performance units would settle at 100%. The number of units paid at the end of the performance period may vary from the amounts reflected in the following tables, based on our actual achievement compared to the performance targets.

• With respect to the treatment of phantom unit awards upon termination due to death, disability or without Cause, we have reflected accelerated vesting based on the length of employment during the vesting period for each award.

• Mr. Cunningham was eligible for retirement as of December 31, 2019. Assuming that Mr. Cunningham had retired on December 31, 2019, his retirement benefits would have consisted of accelerated vesting of phantom units valued at $246,862 and accelerated vesting of performance units valued at $642,062. We assumed that Mr. Cunningham’s performance units granted in 2019 would vest according to the pro-rata formula within his award agreements, and performance units granted prior to 2019 would settle at 100%, therefore the number of units paid upon a retirement scenario could vary from the level presented below.

• The amount shown for “Value of Welfare Benefits” represents amounts equal to the monthly premium payable pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), for medical and dental premiums, multiplied by 12 months for Mr. Cunningham.

• In calculating whether any tax reimbursements were owed to the Named Executive Officers, we used the following assumptions: (a)  no amounts will be discounted as attributable to reasonable compensation, (b) all cash severance payments are contingent upon a change in control and (c) the presumption required under applicable regulations that the equity awards granted in 2019 were contingent upon a change in control could be rebutted. Based on these assumptions, none of the Named Executive Officers would receive any tax reimbursement or “gross-up” payments with respect to any amounts reported in the table below.

- 143 -

• No amounts potentially payable pursuant to the NQDC Plan are included in the table below since neither the form nor amount of any such benefits would be enhanced nor vesting or other provisions accelerated in connection with any of the triggering events disclosed below. Please refer to the section titled “Nonqualified Deferred Compensation” for additional information regarding these benefits.

Named Executive Officer	Cash Payments		Value of Welfare Benefits		Vesting of Equity Awards		Total

Mark T. Cunningham     Termination in connection with or following a Change in Control	$	492,355	$	16,812	$	888,924	$	1,398,091

Compensation Practices as They Relate To Risk Management

Although a significant portion of the compensation provided to the Named Executive Officers is performance-based, we believe our compensation programs do not encourage excessive and unnecessary risk taking by executive officers (or other employees) because these programs are designed to encourage employees to remain focused on both our short- and long-term operational and financial goals.

While annual cash-based incentive bonus awards play an appropriate role in the executive compensation program, the Compensation Committee believes that payment determined based on an evaluation of our performance on a variety of measures, including comparing our performance over the last year to our past performance, mitigates excessive risk-taking that could produce unsustainable gains in one area of performance at the expense of our overall long-term interests. In addition, we set performance goals that we believe are reasonable in light of our past performance and market conditions.

For Named Executive Officers performing all or a majority of their services for us, an appropriate part of total compensation is fixed, while another portion is variable and linked to performance. A portion of the variable compensation we provide is comprised of long-term incentives. A portion of the long-term incentives we provide is in the form of phantom units subject to time-based vesting conditions, which retains value even in a depressed market, so executives are less likely to take unreasonable risks. With respect to our performance units, payouts result in some compensation at levels below full target achievement, in lieu of an “all or nothing” approach. Further, our unit ownership guidelines require certain of our executives to hold at least a specified level of units (in addition to unvested and unsettled equity-based awards), which aligns an appropriate portion of their personal wealth to our long-term performance and the interests of our unitholders. Also, our clawback policy requires the return of annual and long-term incentive compensation for misconduct resulting in a material financial restatement.

Based on the foregoing and our annual review of our compensation programs, we do not believe that our compensation policies and practices are reasonably likely to have a material adverse effect on us or our unitholders.

CEO Pay Ratio

The employees providing services to us are either provided by HLS, which utilizes people employed by HFC to perform services for us, or seconded to us by subsidiaries of HFC, as we do not have any employees for purposes of the pay ratio rules. Rather than providing a pay ratio disclosure that contemplates no employees, we have determined that the disclosure that would be most aligned with the spirit of the pay ratio rules and that would provide our unitholders with more meaningful information would be to provide a ratio using the median employee from the HFC employee population. As a result, we have used the same median employee that was identified by HFC following HFC’s examination of the 2019 taxable wages for all individuals who were employed by HFC in the U.S., Canada, China and the U.K. on December 16, 2019.

HFC identified the median employee by examining the 2019 taxable wages for all of its U.S., Canadian, Chinese and U.K. employees, including its CEO, who were employed by HFC on December 16, 2019. HFC included all U.S., Canadian, Chinese and U.K. employees, whether employed on a full-time, part-time, temporary or seasonal basis. As of December 16, 2019 HFC

- 144 -

employed 3,885 such persons. As permitted by the SEC rules, HFC excluded its 202 employees located in Germany, Austria and the Netherlands since those employees comprise less than 5% of HFC’s 4,087 worldwide employees. HFC did not make any assumptions, adjustments or estimates with respect to the taxable wages other than deducting stock vesting from the taxable wages, and HFC did not annualize the wages for any employees that were not employed by HFC for all of 2019. HFC believes the use of taxable wages is the most appropriate compensation measure since it allows for a consistent measurement for employees in different countries. 

After identifying the median employee based on total taxable wages, HFC calculated annual 2019 compensation for the median employee using the methodology provided in the SEC rules.  HFC’s median employee’s annual 2019 compensation was as follows:

Name	Year	Salary	Bonus	Stock Awards	Non-Equity Incentive Plan Compensation	All Other Compensation	Total
Median Employee	2019	$112,659	—	—	$4,688	$11,885	$129,232

Our 2019 ratio of chief executive officer total compensation to the HFC median employee’s total compensation is reasonably estimated to be 6:1.

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Unitholder Matters

The following table sets forth as of February 14, 2020 the beneficial ownership of common units of HEP held by:

• each person known to us to be a beneficial owner of 5% or more of the common units;

Equity Compensation Plan Table

The following table summarizes information about our equity compensation plans as of December 31, 2019:

Plan Category (1)	Number of securities to be issued upon exercise of outstanding options, warrants and rights	Weighted average exercise price of outstanding options, warrants and rights	Number of securities remaining available for future issuance under equity compensation plans
Equity compensation plans approved by security holders (2)	205,527 (3)	—	1,113,537
Equity compensation plans not approved by security holders	—	—	—
Total	205,527	—	1,113,537

(1) All stock-based compensation plans are described in Note 9 to our consolidated financial statements for the fiscal year ended December 31, 2019.

- 147 -

(2) On April 25, 2012, at a Special Meeting of the Unitholders of the Partnership, the unitholders approved the Long-Term Incentive Plan, which, among other things, provided for an increase in the maximum number of common units reserved for delivery with respect to awards under the Long-Term Incentive Plan to 2,500,000 common units (as adjusted to reflect the two-for-one common unit split that occurred on January 16, 2013). All securities reported as available for future issuances are available from the additional common units approved by unitholders under the Long-Term Incentive Plan. At the time the Long-Term Incentive Plan was originally adopted in 2004, it was not required to be approved by HEP’s unitholders.

(3) Includes 78,182 units subject to performance units granted to key individuals under the Long-Term Incentive Plan assuming the maximum payout level. If the performance units are paid at the target payout level, 41,811 units would be issued upon the vesting of such performance units. Performance units granted in November 2016 with a performance period that ended on December 31, 2019 were not settled until certification by the Board in February 2020 that a performance percentage of 148% was attained for these performance units; however, such awards are not included in this column as outstanding since they are treated for purposes of the preceding executive compensation tables as vesting during 2019 in accordance with SEC rules.

For more information about our Long-Term Incentive Plan, refer to Item 11, “Executive Compensation - Overview of 2019 Executive Compensation Components and Decisions - Long-Term Incentive Equity Compensation.”

Item 13. Certain Relationships and Related Transactions, and Director Independence

Our general partner and its affiliates own 59,630,030 of our common units representing a 57% limited partner interest in us. In addition, the general partner owns the non-economic general partner interest in us. Transactions with our general partner are discussed later in this section.

DISTRIBUTIONS AND PAYMENTS TO THE GENERAL PARTNER AND ITS AFFILIATES

The following table summarizes the distributions and payments to be made by us to our general partner and its affiliates in connection with the ongoing operation and liquidation of HEP. These distributions and payments were determined by and among affiliated entities and, consequently, are not the result of arm’s-length negotiations.

Operational stage

Distributions of available cash to our general partner and its affiliates

In connection with the IDR Restructuring Transaction, our partnership agreement was amended and restated and our general partner agreed to waive $2.5 million of limited partner cash distributions for each twelve consecutive quarters beginning with the quarter ended September 30, 2017. This waiver of limited partner cash distributions will expire after the cash distribution for the second quarter of 2020, which will be made during the third quarter of 2020.We currently distribute all of our available cash to unitholders of record on the applicable record date within 45 days after the end of each quarter, pro rata.

Payments to our general partner and its affiliates

We pay HFC or its affiliates an administrative fee, currently $2.6 million per year, for the provision of various general and administrative services for our benefit. The administrative fee may increase if we make an acquisition that requires an increase in the level of general and administrative services that we receive from HFC or its affiliates. In addition, the general partner is entitled to reimbursement for all expenses it incurs on our behalf, including other general and administrative expenses. These reimbursable expenses include the salaries and the cost of employee benefits of employees of HFC who provide services to us on behalf of HLS. Finally, HLS is required to reimburse HFC for our benefit pursuant to the secondment arrangement for the wages, benefits, and other costs of HFC employees seconded to HLS to perform services at certain of our pipelines and tankage assets. Please read “Omnibus Agreement” and “Secondment Arrangement” below. Our general partner determines the amount of these expenses.

- 148 -

Liquidation stage

Liquidation Upon our liquidation, the partners, including our general partner, will be entitled to receive liquidating distributions according to their particular capital account balances.

OMNIBUS AGREEMENT

Our Omnibus Agreement with HFC and our general partner that addresses the following matters:

• our obligation to pay HFC an annual administrative fee, in the amount of $2.6 million for 2019, for the provision by HFC of certain general and administrative services;

• HFC’s and its affiliates’ agreement not to compete with us under certain circumstances and our right to notice of, and right of first offer to purchase, certain logistics assets constructed by HFC and acquired as part of an acquisition by HFC of refining assets;

• an indemnity by HFC for certain potential environmental liabilities;

• our obligation to indemnify HFC for environmental liabilities related to our assets existing on the date of our initial public offering to the extent HFC is not required to indemnify us; and

• HFC’s right of first refusal to purchase our assets that serve HFC’s refineries.

Payment of general and administrative services fee

Under the Omnibus Agreement, we pay HFC an annual administrative fee, in the amount of $2.6 million for 2019, for the provision of various general and administrative services for our benefit. This fee is subject to annual adjustment for changes in the Producer Price Index Commodities - Finished Goods, et al.Our general partner may agree to further increases in connection with expansions of our operations through the acquisition or construction of new assets or businesses.

The administrative fee includes expenses incurred by HFC and its affiliates to perform centralized corporate functions, such as legal, accounting, treasury, information technology and other corporate services, including the administration of employee benefit plans. The fee does not include salaries of pipeline and terminal personnel or other employees of HFC who perform services for us on behalf of HLS or the cost of their employee benefits, such as 401(k), pension, and health insurance benefits, which are separately charged to us by HFC. We also reimburse HFC and its affiliates for direct general and administrative expenses they incur on our behalf.

Noncompetition

HFC and its affiliates have agreed, for so long as HFC controls our general partner, not to engage in, whether by acquisition or otherwise, the business of operating crude oil pipelines or terminals, refined product pipelines or terminals, intermediate pipelines or terminals, truck racks or crude oil gathering systems in the continental United States. This restriction will not apply to:

• any business operated by HFC or any of its affiliates at the time of the closing of our initial public offering;

• any business conducted by HFC with the approval of our general partner;

• any business or asset that HFC or any of its affiliates acquires or constructs that has a fair market value or construction cost of less than $5 million; and

• any business or asset that HFC or any of its affiliates acquires or constructs that has a fair market value or construction cost of $5 million or more if we have been offered the opportunity to purchase the business or asset at fair market value, and we decline to do so.

The limitations on the ability of HFC and its affiliates to compete with us will terminate if HFC ceases to control our general partner.

Indemnification

Under the Omnibus Agreement, certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers. The Omnibus Agreement provides environmental indemnification with respect to certain transferred assets of up to $7.5 million through 2023 and $15 million through 2026. HFC's indemnification obligations under the Omnibus Agreement do not apply to assets we acquire from third parties, assets we construct or assets we relocate after they are transferred to us from HFC. For the Tulsa loading racks acquired from HFC in August 2009 and the Tulsa logistics and storage assets acquired from Sinclair in December 2009, HFC agreed to indemnify us for environmental liabilities arising from our pre-ownership operations of these assets. Additionally, HFC agreed to indemnify us for any liabilities arising from its operation of our loading racks located at HFC's Tulsa refinery west facility.

- 149 -

We have indemnified HFC and its affiliates against environmental liabilities related to events that occur on our assets after the date we acquired such asset.

Right of first refusal to purchase our assets

The Omnibus Agreement also contains the terms under which HFC has a right of first refusal to purchase our assets that serve its refineries. Before we enter into any contract to sell pipeline and terminal assets serving HFC’s refineries, we must give written notice of the terms of such proposed sale to HFC. The notice must set forth the name of the third-party purchaser, the assets to be sold, the purchase price, all details of the payment terms and all other terms and conditions of the offer. To the extent the third-party offer consists of consideration other than cash (or in addition to cash), the purchase price shall be deemed equal to the amount of any such cash plus the fair market value of such non-cash consideration, determined as set forth in the Omnibus Agreement. HFC will then have the sole and exclusive option for a period of thirty days following receipt of the notice, to purchase the subject assets on the terms specified in the notice.

SECONDMENT ARRANGEMENT

Under HLS’s secondment arrangement with HFC, certain employees of HFC are seconded to HLS, our general partner’s general partner, to provide operational and maintenance services with respect to certain of our pipelines, terminals and refinery processing units, including routine operational and maintenance activities. During their period of secondment, the seconded employees are under the management and supervision of HLS. HLS is required to reimburse HFC for our benefit for the cost of the seconded employees, including their wages and benefits, based on the percentage of the employee’s time spent working for HLS. The secondment arrangement continues until HLS’s mutual agreement with HFC to terminate.

PIPELINE AND TERMINAL, TANKAGE AND THROUGHPUT AGREEMENTS

We serve HFC’s refineries under long-term pipeline, terminal, tankage and refinery processing unit throughput agreements expiring in 2021 to 2036. Under these agreements, HFC agrees to transport, store and process throughput volumes of refined product, crude oil and feedstocks on our pipelines, terminal, tankage and loading rack facilities and refinery processing units that result in minimum annual payments to us. These minimum annual payments or revenues are subject to annual tariff rate adjustments on July 1st each year, based on the PPI or the FERC index. As of December 31, 2019, these agreements with HFC require minimum annualized payments to us of $348.1 million.

HFC’s obligations under these agreements will not terminate if HFC and its affiliates no longer own the general partner. These agreements may be assigned by HFC only with the consent of our conflicts committee.

SUMMARY OF TRANSACTIONS WITH HFC

• On October 31, 2017, we closed on an equity restructuring transaction with HEP Logistics, a wholly-owned subsidiary of HFC and the general partner of HEP, pursuant to which the incentive distribution rights held by HEP Logistics were canceled, and HEP Logistics' 2% general partner interest in HEP was converted into a non-economic general partner interest in HEP. In consideration, we issued 37,250,000 of our common units to HEP Logistics. In addition, HEP Logistics agreed to waive $2.5 million of limited partner cash distributions for each of twelve consecutive quarters beginning with the first quarter the units issued as consideration were eligible to receive distributions. This waiver of limited partner cash distributions will expire after the cash distribution for the second quarter of 2020, which will be made during the third quarter of 2020.

• Revenues received from HFC were $411.8 million, $397.8 million and $377.1 million for the years ended December 31, 2019, 2018 and 2017, respectively.

• HFC charged us general and administrative services under the Omnibus Agreement of $2.6 million for the year ended December 31, 2019, and $2.5 million for each of the years ended December 31, 2018 and 2017.

• We reimbursed HFC for costs of employees supporting our operations of $55.1 million, $51.7 million and $46.6 million for the years ended December 31, 2019, 2018 and 2017, respectively.

• HFC reimbursed us $13.9 million, $10.0 million and $7.2 million for the years ended December 31, 2019, 2018 and 2017, respectively, for expense and capital projects.

• We distributed $150.0 million, $146.8 million and $130.7 million for the years ended December 31, 2019, 2018 and 2017, respectively, to HFC as regular distributions on its common units, subordinated units and general partner interest, including general partner incentive distributions.

• We received direct financing lease payments from HFC for use of our Artesia and Tulsa railyards of $2.1 million, $2.0 million and $0.5 million for the years ended December 31, 2019, 2018 and 2017, respectively.

• We recorded a gain on sales-type leases of $35.2 million during the year ended December 31, 2019 and we received sales-type lease payments of $4.8 million that were not included in revenues for the year ended December 31, 2019.

OTHER RELATED PARTY TRANSACTIONS

Julia Heidenreich, Vice President, Commercial Analysis and Pricing at HFC, is the wife of Richard Voliva, HFC's Executive Vice President and Chief Financial Officer and HLS's President. Ms. Heidenreich received cash and equity compensation totaling $618,329 in 2019. All the cash and equity compensation was paid to Ms. Heidenreich by HFC without any input from HLS. Ms. Heidenreich does not report to Mr. Voliva.

2018 PRIVATE PLACEMENT

As previously disclosed, on January 25, 2018, we entered into a common unit purchase agreement pursuant to which Tortoise Capital Advisors, L.L.C. (“Tortoise”) agreed to purchase in a private placement 3,700,000 common units representing limited partner interests, at a price of $29.73 per common unit (the “private placement”). The private placement closed on February 6, 2018, and we received proceeds of approximately $110 million. The private placement resulted in Tortoise owning greater than 5% of our total outstanding common units.

EXHIBIT 4.6

DESCRIPTION OF OUR COMMON UNITS

“Our,” “we,” “us” and “Holly Energy Partners” as used herein refer to Holly Energy Partners, L.P. or to Holly Energy Partners, L.P. and its subsidiaries collectively, as the context requires. References herein to our “general partner” refer to HEP Logistics Holdings, L.P. and/or Holly Logistic Services, L.L.C., the general partner of HEP Logistics Holdings, L.P., as appropriate.

General

We are a Delaware limited partnership. The rights of our common unitholders are generally covered by Delaware law and our partnership agreement (as amended and restated and in effect as of the date hereof). The terms of our common units are therefore subject to Delaware law, including the Delaware Revised Uniform Limited Partnership Act (the “Delaware Act”), and the common and constitutional law of Delaware.

This exhibit describes the general terms of our common units. Our common units represent limited partner interests that entitle the holders to participate in our cash distributions and to exercise the rights and privileges available to limited partners under our partnership agreement. For a description of the relative rights and preferences of holders of our common units and our general partner in and to cash distributions, please carefully review this section and the section titled “How We Make Cash Distributions.”

This is a summary and does not purport to be complete. Our partnership agreement as it exists on the date of this Annual Report on Form 10-K is incorporated by reference or filed as an exhibit to the Annual Report on Form 10-K of which this exhibit is a part, and amendments or restatements of such will be filed with the Securities and Exchange Commission (the “SEC”) in future periodic or current reports in accordance with the rules of the SEC. You are encouraged to read those documents. For more detailed information about the rights of our common units, you should refer to our partnership agreement and the applicable provisions of Delaware law, including the Delaware Act, for additional information.

Status as Limited Partner or Assignee

Except as described below under “—Limited Liability,” our common units will be fully paid, and unitholders will not be required to make additional capital contributions to us.

Limited Liability

Assuming that a limited partner does not participate in the control of our business within the meaning of the Delaware Act and that he otherwise acts in conformity with the provisions of our partnership agreement, his liability under the Delaware Act will be limited, subject to some possible exceptions, generally to the amount of capital he is obligated to contribute to us in respect of his units plus his share of any undistributed profits and assets wrongfully distributed to it, as described below. If it were determined, however, that the right of, or exercise of the right by, the limited partners as a group:

• to remove or replace our general partner;

• to approve some amendments to our partnership agreement; or

• to take other action under our partnership agreement;

constituted “participation in the control” of our business for the purposes of the Delaware Act, then the limited partners could be held personally liable for our obligations under the laws of Delaware to the same extent as our general partner. This liability would additionally extend to persons who transact business with us who reasonably believe that the limited partner is a general partner based on the conduct of the limited partner. Neither our partnership agreement nor the Delaware Act specifically provides for legal recourse against our general partner if a limited partner were to lose limited liability through any fault of our general partner.

Under the Delaware Act, a limited partnership may not make a distribution to a partner to the extent that at the time of the distribution, after giving effect to the distribution, all liabilities of the partnership, other than liabilities to partners on account of their partnership interests and liabilities for which the recourse of creditors is limited to specific property of the partnership, exceed the fair value of the assets of the limited partnership.

For the purposes of determining the fair value of the assets of a limited partnership, the Delaware Act provides that the fair value of the property subject to liability of which recourse of creditors is limited shall be included in the assets of the limited partnership only to the extent that the fair value of that property exceeds the nonrecourse liability. The Delaware Act provides that a limited partner who receives a distribution and knew at the time of the distribution that the distribution was in violation of the Delaware Act is liable to the limited partnership for the amount of the distribution for three years from the date of the distribution. Under the Delaware Act, an assignee who becomes a substituted limited partner of a limited partnership is liable for the obligations of its assignor to make contributions to the limited partnership, excluding any obligations of the assignor with respect to wrongful distributions, as described above, except the assignee is not obligated for liabilities unknown to it at the time it became a limited partner and that could not be ascertained from the partnership agreement.

We currently own property and conduct business in Texas, New Mexico, Utah, Nevada, Oklahoma, Wyoming, Kansas, Idaho and Washington. We may own property or conduct business in other states in the future. Maintenance of our limited liability as a limited partner of our operating partnership may require compliance with legal requirements in the jurisdictions in which our operating partnership owns property or conducts business, including qualifying our subsidiaries to do business there.

Limitations on the liability of limited partners for the obligations of a limited partnership have not been clearly established in many jurisdictions. If, by virtue of our limited partner interest in our operating partnership or otherwise, it were determined that we were conducting business in any state without compliance with the applicable limited partnership or limited liability company statute, or that the right of, or exercise of the right by, the limited partners as a group, to remove or replace our general partner, to approve some amendments to our partnership agreement, or to take other action under our partnership agreement constituted “participation in the control” of our business for purposes of the statutes of any relevant jurisdiction, then the limited partners could be held personally liable for our obligations under the law of that jurisdiction to the same extent as our general partner under the circumstances. We will operate in a manner that our general partner considers reasonable and necessary or appropriate to preserve the limited liability of the limited partners.

Voting Rights

Our general partner manages and operates us. Unlike the holders of common stock in a corporation, our unitholders have only limited voting rights on matters affecting our business and, therefore, limited ability to influence management’s decisions regarding our business. Our unitholders did not elect our general partner or the board of directors of our general partner’s general partner and have no right to elect our general partner or the board of directors of our general partner’s general partner on an annual or other continuing basis. The board of directors of our general partner’s general partner is chosen by the members of our general partner’s general partner. Furthermore, if unitholders are dissatisfied with the performance of our general partner, they will have little ability to remove our general partner. As a result of these limitations, the price at which the common units trade could be diminished because of the absence or reduction of a takeover premium in the trading price.

The vote of the holders of at least 66 ²/₃% of all outstanding units voting together as a single class is required to remove the general partner. Our unitholders will be unable to remove the general partner without its consent because the general partner and its affiliates own sufficient units to prevent its removal. Our unitholders’ voting rights are further restricted by the partnership agreement provision providing that any units held by a person or group that owns 20% or more of any class of units then outstanding, other than the general partner, its affiliates, their transferees, and persons who acquired such units with the prior approval of the board of directors of the general partner’s general partner, cannot vote on any matter. Our partnership agreement also contains provisions limiting the ability of unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting the unitholders’ ability to influence the manner or direction of management.

In voting its common units, the general partner and its affiliates will have no fiduciary duty or obligation whatsoever to us or the limited partners.

Our unitholders will not have voting rights except with respect to the following matters which require the unitholder vote specified below:

Issuance of additional units	No approval required.
Amendment of the partnership agreement	Certain amendments may be made by the general partner without the approval of the unitholders. Other amendments generally require the approval of a majority of the outstanding units.
Merger of our partnership or the sale of all or substantially all of our assets	Approval of a majority of the outstanding units.
Amendment of the partnership agreement of our operating partnership and other action taken by us as a limited partner of the operating partnership	Approval of a majority of the outstanding units if such amendment or other action would adversely affect our limited partners (or any particular class of limited partners) in any material respect.
Dissolution of our partnership	Approval of a majority of the outstanding units.

Reconstitution of our partnership upon dissolution Approval of a majority of the outstanding units.

Withdrawal of the general partner No approval right. Please read “Description of Our Partnership Agreement—Withdrawal or Removal of our General Partner.”

Removal of the general partner Not less than 66 2/3% of the outstanding units, voting as a single class, including units held by our general partner and its affiliates.

Transfer of the general partner interest No approval right. Please read “Description of Our Partnership Agreement—Transfer of General Partner Interests.”

Transfer of ownership interests in the general partner No approval required at any time.

Transfer of Common Units

The purchase of any of our common units is accomplished through the completion, execution and delivery of a transfer application. Additionally, any later transfers of our common units will not be recorded by the transfer agent or recognized by us unless the transferee executes and delivers a transfer application. By executing and delivering a transfer application, a purchaser or transferee of our common units:

• becomes the record holder of our common units and is an assignee until admitted into our partnership as a substituted limited partner;

• automatically requests admission as a substituted limited partner in our partnership;

• agrees to be bound by the terms and conditions of, and executes, our partnership agreement;

• represents and warrants that such transferee has the capacity, power and authority to enter into the partnership agreement;

• grants powers of attorney to our general partner and any liquidator of us as specified in the partnership agreement; and

• gives the consents and approvals contained in our partnership agreement.

An assignee will become a substituted limited partner of our partnership for the transferred common units upon admission by our general partner and the recording of the name of the assignee on our books and records. Our general partner intends to admit assignees as substituted limited partners on a quarterly basis.

A transferee’s broker, agent or nominee may complete, execute and deliver a transfer application. We are entitled to treat the nominee holder of a common unit as the absolute owner. In that case, the beneficial holder’s rights are limited solely to those that it has against the nominee holder as a result of any agreement between the beneficial owner and the nominee holder.

Common units are securities and are transferable according to the laws governing transfer of securities. In addition to other rights acquired upon transfer, the transferor gives the transferee the right to request admission as a substituted limited partner in our partnership for the transferred common units. A purchaser or transferee of our common units who does not execute and deliver a transfer application obtains only:

• the right to assign the common unit to a purchaser or other transferee; and

• the right to transfer the right to seek admission as a substituted limited partner in our partnership for the transferred common units.

Thus, a purchaser or transferee of our common units who does not execute and deliver a transfer application:

• will not receive cash distributions or federal income tax allocations, unless the common units are held in a nominee or “street name” account and the nominee or broker has executed and delivered a transfer application; and

• may not receive some federal income tax information or reports furnished to record holders of our common units.

The transferor of our common units has a duty to provide the transferee with all information that may be necessary to transfer the common units. The transferor does not have a duty to insure the execution of the transfer application by the transferee and has no liability or responsibility if the transferee neglects or chooses not to execute and forward the transfer application to the transfer agent. Until a common unit has been transferred on our books, we and the transfer agent may treat the record holder of the unit as the absolute owner for all purposes, except as otherwise required by law or stock exchange regulations.

Reports and Records

As soon as practicable, but in no event later than 120 days after the close of each fiscal year, our general partner will furnish or make available to each unitholder of record (as of a record date selected by our general partner) an annual report containing our audited financial statements and a report on those financial statements by our independent public accountants. These financial statements will be prepared in accordance with generally accepted accounting principles. Except for our fourth quarter, we will also furnish or make available summary financial information within 90 days after the close of each quarter.

We will also furnish each unitholder of record with information reasonably required for tax reporting purposes within 90 days after the close of each calendar year. This information is expected to be furnished in summary form so that some complex calculations normally required of partners can be avoided. Our ability to furnish this summary information to unitholders will depend on the cooperation of unitholders in supplying us with specific information. Every unitholder will receive information to assist such unitholder in determining his federal and state tax liability and filing his federal and state income tax returns, regardless of whether he supplies us with information.

A limited partner can, for a purpose reasonably related to the limited partner’s interest as a limited partner, upon reasonable demand and at his own expense, have furnished to such unitholder:

• a current list of the name and last known address of each partner;

• a copy of our tax returns;

• information as to the amount of cash and a description and statement of the agreed value of any other property or services, contributed or to be contributed by each partner and the date on which each became a partner;

• copies of our partnership agreement, our certificate of limited partnership, amendments to either of them and powers of attorney which have been executed under our partnership agreement;

• information regarding the status of our business and financial condition; and

• any other information regarding our affairs as is just and reasonable.

Our general partner may, and intends to, keep confidential from the limited partners trade secrets and other information the disclosure of which our general partner believes in good faith is not in our best interest or which we are required by law or by agreements with third parties to keep confidential.

Listing

Our outstanding common units are listed on the New York Stock Exchange (the “NYSE”) under the symbol “HEP.” Any additional common units we issue will also be listed on the NYSE.

Transfer Agent and Registrar

The transfer agent and registrar for our common units is EQ Shareowner Services.

HOW WE MAKE CASH DISTRIBUTIONS

Distributions of Available Cash

General

Our partnership agreement provides that we will distribute all of our available cash to unitholders of record on the applicable record date within 45 days after the end of each quarter.

In October 2017, our general partner agreed to waive $2.5 million of limited partner cash distributions for each of twelve consecutive quarters beginning with the quarter ending September 30, 2017. This waiver of limited partner cash distributions will expire after the cash distribution for the second quarter of 2020, which will be made during the third quarter of 2020.

Definition of Available Cash

Available cash generally means, for each fiscal quarter, all cash and cash equivalents on hand at the end of the quarter:

• less the amount of cash reserves established by our general partner to:

• provide for the proper conduct of our business;

• comply with applicable law, any of our debt instruments, or other agreements; or

• provide funds for distributions to our unitholders and to our general partner for any one or more of the next four quarters;

• plus all cash and cash equivalents on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter. Working capital borrowings are generally borrowings that are made under our credit facility and in all cases are used solely for working capital purposes or to pay distributions to partners.

Distributions of Cash upon Liquidation

General

If we dissolve in accordance with the partnership agreement, we will sell or otherwise dispose of our assets in a process called liquidation. We will first apply the proceeds of liquidation to the payment of our creditors. We will distribute any remaining proceeds to the unitholders and the general partner, in accordance with their capital account balances, as adjusted to reflect any gain or loss upon the sale or other disposition of our assets in liquidation.

Manner of Adjustments for Income

The manner of the adjustment for gain is set forth in the partnership agreement. We will allocate any gain to the partners in the following manner:

• First, to the general partner to the extent of any residual loss allocations; and

• Second, the balance, if any, to the common unitholders, pro rata.

Manner of Adjustments for Losses

We will generally allocate any loss to the general partner and the unitholders in the following manner:

• First, to the holders of common units pro rata in proportion to the positive balances in their capital accounts until the capital accounts of the common unitholders have been reduced to zero; and

• Thereafter, the balance, if any, 100% to the general partner.

Adjustments to Capital Accounts

We will make adjustments to capital accounts upon the issuance of additional units. In doing so, we will allocate any unrealized and, for tax purposes, unrecognized gain or loss resulting from the adjustments to the unitholders and the general partner in the same manner as we allocate gain or loss upon liquidation. In the event that we make positive adjustments to the capital accounts upon the issuance of additional units, we will allocate any later negative adjustments to the capital accounts resulting from the issuance of additional units or upon our liquidation in a manner which results, to the extent possible, in the general partner’s capital account balances equaling the amount which they would have been if no earlier positive adjustments to the capital accounts had been made.

DESCRIPTION OF OUR PARTNERSHIP AGREEMENT

The following is a summary of the material provisions of our partnership agreement that relate to ownership of our common units. Our second amended and restated partnership agreement, as amended, has been filed with the Commission.

Power of Attorney

Each limited partner, and each person who acquires a unit from a unitholder and executes and delivers a transfer application, grants to our general partner and, if appointed, a liquidator, a power of attorney to, among other things, execute and file documents required for our qualification, continuance or dissolution. The power of attorney also grants the authority for the amendment of, and to make consents and waivers under, our partnership agreement.

Issuance of Additional Securities

Our partnership agreement authorizes us to issue an unlimited number of additional partnership securities and rights to buy partnership securities for the consideration and on the terms and conditions determined by our general partner in its sole discretion without the approval of the unitholders. It is possible that we will fund acquisitions through the issuance of additional common units or other equity securities. Holders of any additional common units or other equity securities we issue may be entitled to share with the then-existing holders of our common units or other equity securities in our cash distributions. In addition, the issuance of additional partnership interests may dilute the value of the interests of the then-existing holders of common units in our net assets. In accordance with Delaware law and the provisions of our partnership agreement, we may also issue additional partnership interests that, in the sole discretion of our general partner, may have special voting rights to which common units are not entitled.

Moreover, the general partner will have the right, which it may from time to time assign in whole or in part to any of its affiliates, to purchase common units or other equity securities whenever, and on the same terms that, we issue those securities to persons other than the general partner and its affiliates, to the extent necessary to maintain its and its affiliates percentage interest, including its interest represented by common units, that existed immediately prior to each issuance. The holders of common units do not have preemptive rights to acquire additional common units or other partnership securities.

Amendments to Our Partnership Agreement

General. Amendments to the partnership agreement may be proposed only by or with the consent of the general partner, which consent may be given or withheld at its option, except as discussed below. In order to adopt a proposed amendment, other than the amendments discussed below, the general partner must seek written approval of the holders of the number of units required to approve the amendment or call a meeting of the limited partners to consider and vote upon the proposed amendment. Except as we describe below, an amendment must be approved by a unit majority.

Prohibited Amendments

No amendment may be made that would:

(1) enlarge the obligations of any limited partner without its consent, unless approved by at least a majority of the type or class of limited partner interests so affected;

(2) enlarge the obligations of, restrict in any way any action by or rights of, or reduce in any way the amounts distributable, reimbursable or otherwise payable by us to the general partner or any of its affiliates without the consent of the general partner, which may be given or withheld in at its option;

(3) change the term of our partnership;

(4) provide that our partnership is not dissolved upon an election to dissolve our partnership by the general partner that is approved by the holders of a unit majority; or

(5) give any person the right to dissolve our partnership other than the general partner’s right to dissolve our partnership with the approval of the holders of a unit majority.

The provision of the partnership agreement preventing the amendments having the effects described in clauses (1) through (5) above can be amended upon the approval of the holders of at least 90% of the outstanding units voting together as a single class (including units owned by our general partner and its affiliates).

No Unitholder Approval

The general partner may generally make amendments to the partnership agreement without the approval of any limited partner or assignee to reflect:

(1) a change in our name, the location of our principal place of business, our registered agent or our registered office;

(2) the admission, substitution, withdrawal, or removal of partners in accordance with the partnership agreement;

(3) a change that the general partner determines to be necessary or appropriate for us to qualify or to continue our qualification as a limited partnership or a partnership in which the limited partners have limited liability under the laws of any state or to ensure that neither we, the operating partnership, nor its subsidiaries will be treated as an association taxable as a corporation or otherwise taxed as an entity for federal income tax purposes;

(4) an amendment that is necessary, in the opinion of our counsel, to prevent us or our general partner or its directors, officers, agents, or trustees from in any manner being subjected to the provisions of the Investment Company Act of 1940, the Investment Advisors Act of 1940, or plan asset regulations adopted under the Employee Retirement Income Security Act of 1974, or the Employee Retirement Income Security Act of 1974, as amended, whether or not substantially similar to plan asset regulations currently applied or proposed;

(5) subject to the limitations on the issuance of additional partnership securities described above, an amendment that the general partner determines to be necessary or appropriate for the authorization of additional partnership securities or rights to acquire partnership securities;

(6) any amendment expressly permitted in the partnership agreement to be made by the general partner acting alone;

(7) an amendment effected, necessitated, or contemplated by a merger agreement that has been approved under the terms of the partnership agreement;

(8) any amendment that the general partner determines to be necessary or appropriate for the formation by us of, or our investment in, any corporation, partnership, or other entity, as otherwise permitted by the partnership agreement;

(9) a change in our fiscal year or taxable year and related changes;

(10) certain mergers or conveyances as set forth in our partnership agreement; or

(11) any other amendments substantially similar to any of the matters described in (1) through (10) above.

In addition, the general partner may make amendments to the partnership agreement without the approval of any limited partner or assignee if the general partner determines that those amendments:

(1) do not adversely affect the limited partners (or any particular class of limited partners) in any material respect;

(2) are necessary or appropriate to satisfy any requirements, conditions, or guidelines contained in any opinion, directive, order, ruling, or regulation of any federal or state agency or judicial authority or contained in any federal or state statute;

(3) are necessary or appropriate to facilitate the trading of limited partner interests or to comply with any rule, regulation, guideline, or requirement of any securities exchange on which the limited partner interests are or will be listed for trading;

(4) are necessary or appropriate for any action taken by the general partner relating to splits or combinations of units under the provisions of the partnership agreement; or

(5) are required to effect the intent of the provisions of the partnership agreement or are otherwise contemplated by the partnership agreement.

Opinion of Counsel and Unitholder Approval

Our general partner will not be required to obtain an opinion of counsel that an amendment will not result in a loss of limited liability to the limited partners or result in our being treated as an entity for federal income tax purposes if one of the amendments described above under “— No Unitholder Approval” should occur. No other amendments to the partnership agreement will become effective without the approval of holders of at least 90% of the outstanding units voting as a single class unless we obtain an opinion of counsel to the effect that the amendment will not affect the limited liability under applicable law of any of our limited partners.

In addition to the above restrictions, any amendment that would have a material adverse effect on the rights or preferences of any type or class of outstanding units in relation to other classes of units will require the approval of at least a majority of the type or class of units so affected. Any amendment that reduces the voting percentage required to take any action must be approved by the affirmative vote of limited partners whose aggregate outstanding units constitute not less than the voting requirement sought to be reduced.

Withdrawal or Removal of Our General Partner

Our general partner may withdraw as general partner without first obtaining approval of any unitholder by giving 90 days’ written notice, and that withdrawal will not constitute a violation of the partnership agreement.

Upon withdrawal of our general partner under any circumstances, other than as a result of a transfer by the general partner of all or a part of its general partner interest in us, the holders of a majority of the outstanding common units may select a successor to that withdrawing general partner. If a successor is not elected, or is elected but an opinion of counsel regarding limited liability and tax matters cannot be obtained, we will be dissolved, wound up, and liquidated, unless within a specified period of time after that withdrawal, the holders of a unit majority agree in writing to continue our business and to appoint a successor general partner.

Our general partner may not be removed unless that removal is approved by the vote of the holders of not less than 66 ²/₃% of our outstanding units, voting together as a single class, including units held by the general partner and its affiliates, and we receive an opinion of counsel regarding limited liability and tax matters. Any removal of our general partner is also subject to the approval of a successor general partner by the vote of the holders of a majority of the outstanding common units.

In the event of removal of our general partner under circumstances where cause exists or withdrawal of the general partner where that withdrawal violates the partnership agreement, a successor general partner will have the option to purchase the general partner interest of the departing general partner for a cash payment equal to the fair market value of such interest. Under all other circumstances where the general partner withdraws or is removed by the limited partners, the departing general partner will have the option to require the successor general partner to purchase the general partner interest of the departing general partner for its fair market value. In each case, this fair market value will be determined by agreement between the departing general partner and the successor general partner. If no agreement is reached, an independent investment banking firm or other independent expert selected by the departing general partner and the successor general partner will determine the fair market value. Or, if the departing general partner and the successor general partner cannot agree upon an independent investment banking firm or other independent expert, then an independent investment banking firm or other independent expert chosen by agreement of the firms or experts selected by each of them will determine the fair market value.

If the option described above is not exercised by either the departing general partner or the successor general partner, the departing general partner’s general partner interest will automatically convert into common units equal to the fair market value of those interests as determined by an investment banking firm or other independent expert selected in the manner described in the preceding paragraph.

In addition, we will be required to reimburse the departing general partner for all amounts due the departing general partner, including, without limitation, all employee-related liabilities, including severance liabilities, incurred for the termination of any employees employed by the departing general partner or its affiliates for our benefit.

Merger, Sale or Other Disposition of Assets

 The partnership agreement generally prohibits the general partner, without the prior approval of the holders of units representing a unit majority, from causing us to, among other things, sell, exchange, or otherwise dispose of all or substantially all of our assets in a single transaction or a series of related transactions, including by way of merger, consolidation, or other combination, or approving on our behalf the sale, exchange, or other disposition of all or substantially all of the assets of our subsidiaries. The general partner may, however, mortgage, pledge, hypothecate, or grant a security interest in all or substantially all of our assets without that approval. The general partner may also sell all or substantially all of our assets under a foreclosure or other realization upon those encumbrances without that approval.

If conditions specified in the partnership agreement are satisfied, the general partner may convert us or any of our subsidiaries into a new limited liability entity or merge us or any of our subsidiaries into, or convey some or all of our assets to, a newly formed entity if the sole purpose of that merger or conveyance is to effect a mere change in our legal form into another limited liability entity. The unitholders are not entitled to dissenters’ rights of appraisal under the partnership agreement or applicable Delaware law in the event of a conversion, merger or consolidation, a sale of substantially all of our assets, or any other transaction or event.

Termination and Dissolution

We will continue as a limited partnership until terminated under the partnership agreement. We will dissolve upon:

(1) the election of the general partner to dissolve us, if approved by the holders of units representing a unit majority;

(2) the sale, exchange, or other disposition of all or substantially all of our assets and properties and our subsidiaries;

(3) the entry of a decree of judicial dissolution of Holly Energy Partners; or

(4) the withdrawal or removal of our general partner or any other event that results in its ceasing to be the general partner other than by reason of a transfer of its general partner interest in accordance with the partnership agreement or withdrawal or removal following approval and admission of a successor.

Upon a dissolution under clause (4), the holders of a unit majority may also elect, within specific time limitations, to reconstitute us and continue our business on the same terms and conditions described in the partnership agreement by forming a new limited partnership on terms identical to those in the partnership agreement and having as general partner an entity approved by the holders of units representing a unit majority, subject to our receipt of an opinion of counsel to the effect that:

• the action would not result in the loss of limited liability of any limited partner; and

• none of Holly Energy Partners, the reconstituted limited partnership, the operating partnership nor any of our other subsidiaries would be treated as an association taxable as a corporation or otherwise be taxable as an entity for federal income tax purposes upon the exercise of that right to continue.

Liquidation and Distribution of Proceeds

Upon our dissolution, unless we are reconstituted and continued as a new limited partnership, the person authorized to wind up our affairs (the liquidator) will, acting with all the powers of our general partner that the liquidator deems necessary or desirable in its good faith judgment, liquidate our assets and apply the proceeds of the liquidation as provided in “How We Make Cash Distributions—Distributions of Cash upon Liquidation.” The liquidator may defer liquidation or distribution of our assets for a reasonable period or distribute assets to partners in kind if it determines that a sale would be impractical or would cause undue loss to the partners.

Transfer of General Partner Interests

At any time, our general partner may transfer all or any part of its general partner interest in us to another person without the approval of our common unitholders. As a condition of this transfer, the transferee must, among other things, assume the rights and duties of the general partner, agree to be bound by the provisions of the partnership agreement, and furnish an opinion of counsel regarding limited liability and tax matters.

Subject to certain exceptions, our general partner and its affiliates may at any time transfer units to one or more persons, without unitholder approval.

Transfer of Ownership Interests in Our General Partner and in Our General Partner’s General Partner

At any time, the partners of our general partner and the members of Holly Logistic Services, L.L.C., the general partner of our general partner, may sell or transfer all or part of their respective partnership or membership interests in our general partner or Holly Logistic Services, L.L.C. to an affiliate or a third party without the approval of our unitholders.

Change of Management Provisions

Our partnership agreement contains specific provisions that are intended to discourage a person or group from attempting to remove HEP Logistics Holdings, L.P. as our general partner or otherwise change management. If any person or group other than the general partner and its affiliates acquires beneficial ownership of 20% or more of any class of units, that person or group loses voting rights on all of its units. This loss of voting rights does not apply to any person or group that acquires the units from our general partner or its affiliates and any transferees of that person or group approved by our general partner or to any person or group who acquires the units with the prior approval of the board of directors.

The partnership agreement also provides that if the general partner is removed under circumstances where cause does not exist and units held by the general partner and its affiliates are not voted in favor of that removal, the general partner will have the right to convert its general partner interest into common units or to receive cash in exchange for those interests.

Limited Call Right

If at any time the general partner and its affiliates hold more than 80% of the then-issued and outstanding partnership securities of any class, the general partner will have the right, which it may assign in whole or in part to any of its affiliates or to us, to acquire all, but not less than all, of the remaining partnership securities of the class held by unaffiliated persons as of a record date to be selected by the general partner, on at least ten but not more than 60 days’ notice. The purchase price in the event of this purchase is the greater of: (1) the highest cash price paid by either of the general partner or any of its affiliates for any partnership securities of the class purchased within the 90 days preceding the date on which the general partner first mails notice of its election to purchase those partnership securities; and (2) the current market price as of the date three days before the date the notice is mailed.

As a result of the general partner’s right to purchase outstanding partnership securities, a holder of partnership securities may have his partnership securities purchased at an undesirable time or price. The tax consequences to a unitholder of the exercise of this call right are the same as a sale by that unitholder of his common units in the market.

Non-Citizen Assignees; Redemption

 If we are or become subject to federal, state or local laws or regulations that, in the reasonable determination of the general partner, create a substantial risk of cancellation or forfeiture of any property that we have an interest in because of the nationality, citizenship or other related status of any limited partner or assignee, we may redeem the units held by the limited partner or assignee at their current market price. In order to avoid any cancellation or forfeiture, the general partner may require each limited partner or assignee to furnish information about his nationality, citizenship or related status. If a limited partner or assignee fails to furnish information about this nationality, citizenship or other related status within 30 days after a request for the information or the general partner determines after receipt of the information that the limited partner or assignee is not an eligible citizen, the limited partner or assignee may be treated as a non-citizen assignee. In addition to other limitations on the rights of an assignee that is not a substituted limited partner, a non-citizen assignee does not have the right to direct the voting of his units and may not receive distributions in kind upon our liquidation.

Meetings; Voting

Except as described below regarding a person or group owning 20% or more of any class of units then outstanding, unitholders or assignees who are record holders of units on the record date will be entitled to notice of, and to vote at, meetings of our limited partners and to act upon matters for which approvals may be solicited. Common units that are owned by an assignee who is a record holder, but who has not yet been admitted as a limited partner, will be voted by the general partner at the written direction of the record holder. Absent direction of this kind, the common units will not be voted, except that, in the case of common units held by the general partner on behalf of non-citizen assignees, the general partner will distribute the votes on those common units in the same ratios as the votes of limited partners on other units are cast.

The general partner does not anticipate that any meeting of unitholders will be called in the foreseeable future. Any action that is required or permitted to be taken by the unitholders may be taken either at a meeting of the unitholders or without a meeting if consents in writing describing the action so taken are signed by holders of the number of units necessary to authorize or take that action at a meeting. Meetings of the unitholders may be called by the general partner or by unitholders owning at least 20% of the outstanding units of the class for which a meeting is proposed. Unitholders may vote either in person or by proxy at meetings. The holders of a majority of the outstanding units of the class or classes for which a meeting has been called, represented in person or by proxy, will constitute a quorum unless any action by the unitholders requires approval by holders of a greater percentage of the units, in which case the quorum will be the greater percentage.

Each record holder of a unit has a vote according to his percentage interest in us, although additional limited partner interests having special voting rights could be issued. Please read “— Issuance of Additional Securities.” However, if at any time any person or group, other than the general partner and its affiliates, or a direct or subsequently approved transferee of the general partner or its affiliates, acquires, in the aggregate, beneficial ownership of 20% or more of any class of units then outstanding, that person or group will lose voting rights on all of its units and the units may not be voted on any matter and will not be considered to be outstanding when sending notices of a meeting of unitholders, calculating required votes, determining the presence of a quorum, or for other similar purposes. Common units held in nominee or street name account will be voted by the broker or other nominee in accordance with the instruction of the beneficial owner unless the arrangement between the beneficial owner and his nominee provides otherwise.

Any notice, demand, request, report, or proxy material required or permitted to be given or made to record holders of common units under the partnership agreement will be delivered to the record holder by us or by the transfer agent.

Debt Instruments [Abstract]

Debt

Debt

Credit Agreement

We have a $1.4 billion senior secured revolving credit facility (the “Credit Agreement”) expiring in July 2022. The Credit Agreement is available to fund capital expenditures, investments, acquisitions, distribution payments and working capital and for general partnership purposes. The Credit Agreement is also available to fund letters of credit up to a $50 million sub-limit, and it contains an accordion feature giving us the ability to increase the size of the facility by up to $300 million with additional lender commitments.

Our obligations under the Credit Agreement are collateralized by substantially all of our assets, and indebtedness under the Credit Agreement is guaranteed by our material, wholly-owned subsidiaries. The Credit Agreement requires us to maintain compliance

with certain financial covenants consisting of total leverage, senior secured leverage, and interest coverage. It also limits or restricts our ability to engage in certain activities. If, at any time prior to the expiration of the Credit Agreement, HEP obtains two investment grade credit ratings, the Credit Agreement will become unsecured and many of the covenants, limitations, and restrictions will be eliminated.

Indebtedness under the Credit Agreement bears interest, at our option, at either (a) the reference rate as announced by the administrative agent plus an applicable margin (ranging from 0.50% to 1.50%) or (b) at a rate equal to LIBOR plus an applicable margin (ranging from 1.50% to 2.50%). In each case, the applicable margin is based upon the ratio of our funded debt (as defined in the Credit Agreement) to EBITDA (earnings before interest, taxes, depreciation and amortization, as defined in the Credit Agreement). The weighted-average interest rates on our Credit Agreement borrowings for both the years ending December 31, 2019 and 2018, were 4.24%. We incur a commitment fee on the unused portion of the Credit Agreement at an annual rate ranging from 0.25% to 0.50% based upon the ratio of our funded debt to EBITDA for the four most recently completed fiscal quarters.

We may prepay all loans at any time without penalty, except for tranche breakage costs. If an event of default exists under the Credit Agreement, the lenders will be able to accelerate the maturity of all loans outstanding and exercising other rights and remedies. We were in compliance with the covenants as of December 31, 2019.

Senior Notes

As of December 31, 2019, we had $500 million aggregate principal amount of 6% senior unsecured notes due in 2024 (the "6% Senior Notes"). The 6% Senior Notes were unsecured and imposed certain restrictive covenants, including limitations on our ability to incur additional indebtedness, make investments, sell assets, incur certain liens, pay distributions, enter into transactions with affiliates and enter into mergers. We were in compliance with the restrictive covenants for the 6% Senior Notes as of December 31, 2019.

On February 4, 2020, we closed a private placement of $500 million in aggregate principal amount of 5% senior unsecured notes due in 2028 (the "5% Senior Notes"). On February 5, 2020, we redeemed the existing $500 million 6% Senior Notes at a redemption cost of $522.5 million. We will record any early extinguishment losses associated with this redemption during the first quarter of 2020. We funded the $522.5 million redemption with proceeds from the issuance of our 5% Senior Notes and borrowings under our Credit Agreement.

The 5% Senior Notes are unsecured and impose certain restrictive covenants, including limitations on our 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 5% Senior Notes are rated investment grade by either Moody’s or 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 at varying premiums over face value under the 5% Senior Notes.

Indebtedness under the 5% Senior Notes is guaranteed by our wholly-owned subsidiaries (other than Holly Energy Finance Corp. and certain immaterial subsidiaries).

On January 4, 2017, we redeemed the $300 million aggregate principal amount of 6.5% senior notes due in 2020 (the "6.5% Senior Notes") at a redemption cost of $309.8 million, at which time we recognized a $12.2 million early extinguishment loss consisting of a $9.8 million debt redemption premium and unamortized discount and financing costs of $2.4 million. We funded the redemption with borrowings under our Credit Agreement.

Our purchase and contribution agreements with HFC with respect to the intermediate pipelines acquired in 2005 and the crude pipelines and tankage assets acquired in 2008, restrict us from selling these pipelines and terminals acquired from HFC.

Fair Value Disclosures [Abstract]

Financial Instruments

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. 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.

Financial Instruments

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

The carrying amounts and estimated fair values of our senior notes were as follows:

		December 31, 2019				December 31, 2018
Financial Instrument	Fair Value Input Level	Carrying Value		Fair Value		Carrying Value		Fair Value
		(In thousands)
Liabilities:
6.0% Senior Notes	Level 2	$	496,531	$	522,045	$	495,900	$	488,310

Level 2 Financial Instruments

Our senior notes are measured at fair value using Level 2 inputs. The fair value of the senior notes is based on market values provided by a third-party bank, which were derived using market quotes for similar type debt instruments. See Note 10 for additional information.

Non-Recurring Fair Value Measurements

For gains on sales-type leases recognized during the third quarter of 2019, the estimated fair value of the underlying leased assets at contract inception and the present value of the estimated unguaranteed residual asset at the end of the lease term are used in determining the net investment in leases and related gain on sales-type leases recorded.  The asset valuation estimates include Level 3 inputs based on a replacement cost valuation method.

Supplemental Guarantor / Non-Guarantor Financial Information

Supplemental Guarantor/Non-Guarantor Financial Information

Obligations of HEP (“Parent”) under the 6% Senior Notes have been jointly and severally guaranteed by each of its direct and indirect 100% owned subsidiaries (“Guarantor Subsidiaries”). These guarantees are full and unconditional, subject to certain customary release provisions. These circumstances include (i) when a Guarantor Subsidiary is sold or sells all or substantially all of its assets, (ii) when a Guarantor Subsidiary is declared “unrestricted” for covenant purposes, (iii) when a Guarantor Subsidiary's guarantee of other indebtedness is terminated or released and (iv) when the requirements for legal defeasance or covenant defeasance or to discharge the senior notes have been satisfied.

On February 4, 2020, we closed a private placement of the 5% Senior Notes, and on February 5, 2020, we redeemed the existing 6% Senior Notes (see Note 10). Obligations of HEP (“Parent”) under the 5% Senior Notes have been jointly and severally guaranteed by each of its direct and indirect 100% owned subsidiaries (“Guarantor Subsidiaries”). These guarantees are full and unconditional, subject to certain customary release provisions. These circumstances include (i) when a Guarantor Subsidiary is sold or sells all or substantially all of its assets, (ii) when a Guarantor Subsidiary is declared “unrestricted” for covenant purposes, (iii) when a Guarantor Subsidiary's guarantee of other indebtedness is terminated or released and (iv) when the requirements for legal defeasance or covenant defeasance or to discharge the senior notes have been satisfied.

The following financial information presents condensed consolidating balance sheets, statements of comprehensive income, and statements of cash flows of the Parent, the Guarantor Subsidiaries and the Non-Guarantor subsidiaries. The information has been presented as if the Parent accounted for its ownership in the Guarantor Subsidiaries and the Guarantor Restricted Subsidiaries accounted for the ownership of the Non-Guarantor Non-Restricted Subsidiaries, using the equity method of accounting.

Net Income Per Limited Partner Unit

Net Income per Limited Partner Unit [Abstract]

Net Income per Limited Partner Unit [Text Block]

Net Income Per Limited Partner Unit

Net income per unit applicable to the limited partners was computed using the two-class method since we had more than one class of participating securities during the period from January 1, 2017 through October 31, 2017.  The classes of participating securities during this period included common units, general partner units and IDRs. Due to the equity restructuring transaction described in Note 1, as of November 1, 2017, we had one class of security outstanding, common units. To the extent net income attributable to the partners exceeds or is less than cash distributions, this difference is allocated to the partners based on their weighted-average ownership percentage during the period, after consideration of any priority allocations of earnings.  The dilutive securities are immaterial for all periods presented.

See Note 1 for a description of the equity restructuring of the general partner interest owned by HEP Logistics, our general partner, and its IDRs that occurred on October 31, 2017. After this equity restructuring, the general partner interest is no longer entitled

to any distributions and none were made on the general partner interest after October 31, 2017. In connection with this equity restructuring, HEP issued 37,250,000 of its common units to HEP Logistics on October 31, 2017.

When our financial statements are retrospectively adjusted after a dropdown transaction, the earnings of the acquired business, prior to the closing of the transaction, are allocated entirely to our general partner and presented as net income (loss) attributable to Predecessors. The earnings per unit of our limited partners prior to the close of the transaction do not change as a result of the dropdown. After the closing of a dropdown transaction, the earnings of the acquired business are allocated in accordance with our partnership agreement as previously described.

For purposes of applying the two-class method including the allocation of cash distributions in excess of earnings, net income per limited partner unit is computed as follows:

Description of Business and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2019

Accounting Policies [Abstract]

Business Description and Basis of Presentation

Holly Energy Partners, L.P. (“HEP”) together with its consolidated subsidiaries, is a publicly held master limited partnership. As of December 31, 2019, HollyFrontier Corporation (“HFC”) and its subsidiaries own a 57% limited partner interest and the non-economic general partner interest in HEP. We commenced operations on July 13, 2004, upon the completion of our initial public offering. In these consolidated financial statements, the words “we,” “our,” “ours” and “us” refer to HEP unless the context otherwise indicates.

On October 31, 2017, we closed on an equity restructuring transaction with HEP Logistics Holdings, L.P. (“HEP Logistics”), a wholly-owned subsidiary of HFC and the general partner of HEP, pursuant to which the incentive distribution rights ("IDRs") held by HEP Logistics were canceled, and HEP Logistics' 2% general partner interest in HEP was converted into a non-economic general partner interest in HEP. In consideration, we issued 37,250,000 of our common units to HEP Logistics. In addition, HEP Logistics agreed to waive $2.5 million of limited partner cash distributions for each of twelve consecutive quarters beginning with the first quarter the units issued as consideration were eligible to receive distributions. This waiver of limited partner cash distributions will expire after the cash distribution for the second quarter of 2020, which will be made during the third quarter of 2020. As a result of this transaction, no distributions were made on the general partner interest after October 31, 2017.

On January 25, 2018, we entered into a common unit purchase agreement in which certain purchasers agreed to purchase in a private placement 3,700,000 common units representing limited partner interests, at a price of $29.73 per common unit. The private placement closed on February 6, 2018, and we received proceeds of approximately $110 million, which were used to repay indebtedness under our revolving credit facility.

We own and operate petroleum product and crude oil pipelines, terminal, tankage and loading rack facilities and refinery processing units that support the refining and marketing operations of HFC and other refineries in the Mid-Continent, Southwest and Northwest regions of the United States and Delek US Holdings, Inc.’s (“Delek”) refinery in Big Spring, Texas. Additionally, we own a 75% interest in the UNEV Pipeline, LLC (“UNEV”), a 50% interest in Osage Pipe Line Company, LLC (“Osage”), a 50% interest in Cheyenne Pipeline LLC, and a 50% interest in Cushing Connect Pipeline & Terminal LLC.

We operate in two reportable segments, a Pipelines and Terminals segment and a Refinery Processing Unit segment. Disclosures around these segments are discussed in Note 16.

Our Pipelines and Terminals segment consists of:

• 26 main pipeline segments

• Crude gathering networks in Texas and New Mexico

• 10 refined product terminals

• 1 crude terminal

• 31,800 track feet of rail storage located at two facilities

• 7 locations with truck and/or rail racks

• Tankage at all six of HFC's refining facility locations

Our Refinery Processing Unit segment consists of five refinery processing units at two of HFC's refining facility locations.

We generate revenues by charging tariffs for transporting petroleum products and crude oil through our pipelines, by charging fees for terminalling and storing refined products and other hydrocarbons, providing other services at our storage tanks and terminals and by charging fees for processing hydrocarbon feedstocks through our refinery processing units. We do not take ownership of products that we transport, terminal, store or process, and therefore, we are not exposed directly to changes in commodity prices.

Consolidation and Common Control Transactions, Policy

Principles of Consolidation and Common Control Transactions

The consolidated financial statements include our accounts, our Predecessor's (defined below) and those of subsidiaries and joint ventures that we control. All significant intercompany transactions and balances have been eliminated. Certain prior period balances have been reclassified for consistency with current year presentation.

Most of our acquisitions from HFC occurred while we were a consolidated variable interest entity of HFC. Therefore, as an entity under common control with HFC, we recorded these acquisitions on our balance sheets at HFC's historical basis instead of our purchase price or fair value. U.S. generally accepted accounting principles ("GAAP") require transfers of a business between entities under common control to be accounted for as though the transfer occurred as of the beginning of the period of transfer,

and prior period financial statements and financial information are retrospectively adjusted to include the historical results and assets of the acquisitions from HFC for all periods presented prior to the effective dates of each acquisition. We refer to the historical results of the acquisitions prior to their respective acquisition dates as those of our "Predecessor." Many of these transactions are cash purchases and do not involve the issuance of equity; however, GAAP requires the retrospective adjustment of financial statements. Therefore, in such transactions, the prior year balance sheet includes as equity the amount of cost incurred by HFC to that date.

Use of Estimates, Policy

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 and Cash Equivalents, Policy

Cash and Cash Equivalents

For purposes of the statements of cash flows, we consider all highly liquid investments with maturities of three months or less at the time of purchase to be cash equivalents. The carrying amounts reported on the balance sheets approximate fair value due to the short-term maturity of these instruments.

Accounts Receivable, Policy

Accounts Receivable

The majority of the accounts receivable are due from affiliates of HFC or independent 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, may be required. Credit losses are charged to income when accounts are deemed uncollectible and historically have been minimal.

Properties and Equipment, Policy

Properties and Equipment

Properties and equipment are stated at cost. Properties and equipment acquired from HFC while under common control of HFC are stated at HFC's historical basis. Depreciation is provided by the straight-line method over the estimated useful lives of the assets, primarily 15 to 25 years for terminal facilities and tankage, 25 to 30 years for pipelines, 25 years for refinery processing units and 3 to 10 years for corporate and other assets. We depreciate assets acquired under capital leases over the lesser of the lease term or the economic life of the assets. Maintenance, repairs and minor replacements are expensed as incurred. Costs of replacements constituting improvements are capitalized.

Intangible Assets, Policy

Intangible Assets

Intangible assets include transportation agreements and acquired customer relationship intangible assets. Intangible assets are stated at acquisition date fair value and are being amortized over their useful lives using the straight-line method.

Goodwill and Long-Lived Assets, Policy

Goodwill and Long-Lived Assets

Goodwill represents the excess of our cost of an acquired business over the fair value of the assets acquired, less liabilities assumed. Goodwill is not amortized. We test goodwill at the reporting unit level for impairment annually and between annual tests if events or changes in circumstances indicate the carrying amount may exceed fair value. Our goodwill impairment testing first entails a comparison of our reporting unit fair values relative to their respective carrying values, including goodwill. If carrying value exceeds fair value for a reporting unit, we measure goodwill impairment as the excess of the carrying amount of reporting unit goodwill over the implied fair value of that goodwill based on estimates of the fair value of all assets and liabilities in the reporting unit.

In 2019, we assessed qualitative factors such as macroeconomic conditions, industry considerations, cost factors, and reporting unit financial performance and determined it was not more likely than not that the fair value of our reporting units were less than the respective carrying value. Therefore, in accordance with GAAP, further testing was not required. In 2018, we used the present value of the expected future net cash flows and market multiple analyses to determine the estimated fair values of the reporting units. The impairment test requires the use of projections, estimates and assumptions as to the future performance of our operations. Actual results could differ from projections resulting in revisions to our assumptions, and if required, could result in the recognition of an impairment loss.

We evaluate long-lived assets, including finite intangible 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.

There have been no impairments to goodwill or our long-lived assets through December 31, 2019.

Investment in Equity Method Investments, Policy

Investment in Equity Method Investments

We account for our interests in noncontrolling joint venture interests using the equity method of accounting, whereby we record our pro-rata share of earnings of these companies, and contributions to and distributions from the joint ventures as adjustments to our investment balances. The difference between the cost of an investment and our proportionate share of the underlying equity in net assets recorded on the investee's books is allocated to the various assets and liabilities of the equity method investment.

The following table summarizes our recorded investments compared to our share of underlying equity for each investee. We are amortizing the differences as adjustments to our pro-rata share of earnings over the useful lives of the underlying assets of these joint ventures.

Asset Retirement Obligations, Policy

Asset Retirement Obligations

We record legal obligations associated with the retirement of certain of our long-lived assets that result from the acquisition, construction, development and/or the normal operation of our long-lived assets. The fair value of the estimated cost to retire a tangible long-lived asset is recorded in the period in which the liability is incurred and when a reasonable estimate of the fair value of the liability can be made. For our pipeline assets, the right-of-way agreements typically do not require the dismantling, removal and reclamation of the right-of-way upon cessation of the pipeline service. Additionally, management is unable to predict when, or if, our pipelines and related facilities would become obsolete and require decommissioning. Accordingly, we have recorded no liability or corresponding asset related to an asset retirement obligation for the majority of our pipelines as both the amounts and timing of such potential future costs are indeterminable. For our remaining assets, at December 31, 2019 and 2018, we have asset retirement obligations of $7.7 million and $8.9 million, respectively, that are recorded under “Other long-term liabilities” in our consolidated balance sheets.

Class B Unit, Policy

Class B Unit

Under the terms of the transaction to acquire HFC's 75% interest in UNEV, we issued HFC a Class B unit comprising a noncontrolling equity interest in a wholly-owned subsidiary subject to redemption to the extent that HFC is entitled to a 50% interest in our share of annual UNEV earnings before interest, income taxes, depreciation, and amortization above $30 million beginning July 1, 2016, and ending in June 2032, subject to certain limitations. Such contingent redemption payments are limited to the unredeemed value of the Class B Unit. However, to the extent earnings thresholds are not achieved, no redemption payments are required. No redemption payments have been required to date.

Contemporaneously with this transaction, HFC (our general partner) agreed to forego its right to incentive distributions of up to $1.25 million per quarter over twelve consecutive quarterly periods following the closing of the transaction and up to an additional four quarters if HFC's Woods Cross refinery expansion did not attain certain thresholds. HEP Logistics' waiver of its right to incentive distributions of $1.25 million per quarter ended with the distribution paid in the third quarter of 2016.

Pursuant to the terms of the transaction agreements, the Class B unit increases by the amount of each foregone incentive distribution and by a 7% factor compounded annually on the outstanding unredeemed balance through its expiration date. At our option, we may redeem, in whole or in part, the Class B unit at the current unredeemed value based on the calculation described. The Class B unit had a carrying value of 49.4 million at December 31, 2019, and 46.2 million at December 31, 2018.

Revenue Recognition, Policy

Revenue Recognition

Revenues are generally recognized as products are shipped through our pipelines and terminals, feedstocks are processed through our refinery processing units or other services are rendered. The majority of our contracts with customers meet the definition of a lease since (1) performance of the contracts is dependent on specified property, plant, or equipment and (2) it is remote that one or more parties other than the customer will take more than a minor amount of the output associated with the specified property, plant, or equipment. Prior to the adoption of the new lease standard (see below), we bifurcated the consideration received between lease and service revenue. The new lease standard allows the election of a practical expedient whereby a lessor does not have to separate non-lease (service) components from lease components under certain conditions. The majority of our contracts meet these conditions, and we have made this election for those contracts. Under this practical expedient, we treat the combined components as a single performance obligation in accordance with Accounting Standards Codification (“ASC”) 606, which largely codified ASU 2014-09, if the non-lease (service) component is the dominant component. If the lease component is the dominant component, we treat the combined components as a lease in accordance with ASC 842, which largely codified ASU 2016-02.

See Note 4 for further discussion of revenue recognition.

Prior to the adoption of ASC 606 on January 1, 2018, billings to customers for their obligations under their quarterly minimum revenue commitments were recorded as deferred revenue liabilities if the customer had the right to receive future services for these billings. The revenue was recognized at the earlier of:

• the customer receiving the future services provided by these billings,

• the period in which the customer was contractually allowed to receive the services expired, or

• our determination that we would not be required to provide services within the allowed period.

We determined that we would not be required to provide services within the allowed period when, based on current and projected shipping levels, our pipeline systems would not have the necessary capacity to enable a customer to exceed its minimum volume levels to such a degree as to utilize the shortfall credit within its respective contractual shortfall make-up period.

We have additional revenues under an operating lease to a third party of an interest in the capacity of one of our pipelines.

We have other cost reimbursement provisions in our throughput / storage agreements providing that customers (including HFC) reimburse us for certain costs. Such reimbursements are recorded as revenue or deferred revenue depending on the nature of the cost. Deferred revenue is recognized over the remaining contractual term of the related throughput agreement.

Taxes billed and collected from our pipeline and terminal customers are recorded on a net basis with no effect on net income.

Several of our contracts include incentive or reduced tariffs once a certain quarterly volume is met. Revenue from the variable element of these transactions is recognized based on the actual volumes shipped as it relates specifically to rendering the services during the applicable quarter.

The majority of our long-term transportation contracts specify minimum volume requirements, whereby, we bill a customer for a minimum level of shipments in the event a customer ships below their contractual requirements. If there are no future performance obligations, we will recognize these deficiency payments in revenue.

In certain of these throughput agreements, a customer may later utilize such shortfall billings as credit towards future volume shipments in excess of its minimum levels within its respective contractual shortfall make-up period. Such amounts represent an obligation to perform future services, which may be initially deferred and later recognized as revenue based on estimated future shipping levels, including the likelihood of a customer’s ability to utilize such amounts prior to the end of the contractual shortfall make-up period. We recognize these deficiency payments in revenue when we do not expect we will be required to satisfy these performance obligations in the future based on the pattern of rights exercised by the customer.

Environmental Costs, Policy

Environmental Costs

Environmental costs are expensed 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, time frame and extent of required remedial and clean-up activities and are subject to periodic adjustments based on currently available information.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC occurring or existing prior to the date of such transfers. We have an

environmental agreement with Delek with respect to pre-closing environmental costs and liabilities relating to the pipelines and terminals acquired from Delek in 2005, under which Delek will indemnify us subject to certain monetary and time limitations. Environmental costs recoverable through insurance, indemnification agreements or other sources are included in other assets to the extent such recoveries are considered probable.

Income Tax, Policy

Income Tax

We are subject to the Texas margin tax that is based on our Texas sourced taxable margin. The tax is calculated by applying a tax rate to a base that considers both revenues and expenses and therefore has the characteristics of an income tax.

We are organized as a pass-through entity for federal income tax purposes. As a result, our partners are responsible for federal income taxes based on their respective share of taxable income.

Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under the partnership agreement.

Net Income per Limited Partners' Unit, Policy

Net Income per Limited Partners' Unit

Net income per unit applicable to the limited partners was computed using the two-class method since we had more than one class of participating securities during the period from January 1, 2017 through October 31, 2017.  The classes of participating securities during this period included common units, general partner units and IDRs. Due to the equity restructuring transaction described above, as of December 31, 2017, we had one class of security outstanding, common units. To the extent net income attributable to the partners exceeds or is less than cash distributions, this difference is allocated to the partners based on their weighted-average ownership percentage during the period, after consideration of any priority allocations of earnings. Other participating securities and dilutive securities are not significant.

New Accounting Pronouncements, Policy

Accounting Pronouncement Adopted During the Periods Presented

Goodwill Impairment Testing

In January 2017, Accounting Standard Update (“ASU”) 2017-04, “Simplifying the Test for Goodwill Impairment,” was issued amending the testing for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under this standard, goodwill impairment is measured as the excess of the carrying amount of the reporting unit over the related fair value. We adopted this standard effective in the second quarter of 2019, and the adoption of this standard had no effect on our financial condition, results of operations or cash flows.

Leases

In February 2016, ASU No. 2016-02, “Leases” (“ASC 842”) was issued requiring leases to be measured and recognized as a lease liability, with a corresponding right-of-use asset on the balance sheet. We adopted this standard effective January 1, 2019, and we elected to adopt using the modified retrospective transition method, whereby comparative prior period financial information will not be restated and will continue to be reported under the lease accounting standard in effect during those periods. We also elected practical expedients provided by the new standard, including the package of practical expedients and the short-term lease recognition practical expedient, which allows an entity to not recognize on the balance sheet leases with a term of 12 months or less. Upon adoption of this standard, we recognized $78.4 million of lease liabilities and corresponding right-of-use assets on our consolidated balance sheet. See Notes 4 and 5 of Notes to the Consolidated Financial Statements for additional information on our lease policies.

Revenue Recognition

In May 2014, an accounting standard update was issued requiring revenue to be recognized when promised goods or services are transferred to customers in an amount that reflects the expected consideration for these goods or services. This standard had an effective date of January 1, 2018, and we accounted for the new guidance using the modified retrospective implementation method, whereby a cumulative effect adjustment was recorded to retained earnings as of the date of initial application. In preparing for adoption, we evaluated the terms, conditions and performance obligations under our existing contracts with customers. Furthermore, we implemented policies to comply with this new standard. See above and Note 4 for additional information on our revenue recognition policies.

Business Combinations

In December 2014, an accounting standard update was issued to provide new guidance on the definition of a business in relation to accounting for identifiable intangible assets in business combinations. This standard had an effective date of January 1, 2018, and had no effect on our financial condition, results of operations or cash flows.

Financial Assets and Liabilities

In January 2016, an accounting standard update was issued requiring changes in the accounting and disclosures for financial instruments. This standard was effective beginning with our 2018 reporting year and had no effect on our financial condition, results of operations or cash flows.

New Accounting Pronouncements Not yet Adopted

Accounting Pronouncements Not Yet Adopted

Credit Losses Measurement

In June 2016, ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” was issued requiring measurement of all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This standard is effective January 1, 2020, and our preliminary review of historic and expected credit losses indicates the amount of expected credit losses upon adoption would not have a material impact on our financial condition, results of operations or cash flows.

Environmental Remediation Obligations [Abstract]

Environmental

Environmental

We expensed $0.5 million, $0.8 million and $0.5 million for the years ended December 31, 2019, 2018 and 2017, respectively, for environmental remediation obligations. The accrued environmental liability related to environmental clean-up projects for which we have assumed liability or for which indemnity provided by HFC has expired reflected in our consolidated balance sheets was $5.5 million and $6.3 million as of the years ended December 31, 2019 and 2018, respectively, of which $3.5 million and $4.3 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.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC and occurring or existing prior to the date of such transfers. As of both December 31, 2019 and 2018, our consolidated balance sheets included additional accrued environmental liabilities of $0.5 million for HFC indemnified liabilities, and other assets included equal and offsetting balances representing amounts due from HFC related to indemnifications for environmental remediation liabilities.

Commitments and Contingencies

Commitments and Contingencies

We lease certain facilities and pipelines under operating leases and finance leases, most of which contain renewal options. These operating leases have various termination dates through 2035. See Note 5 of Notes to Consolidated Financial Statements for a schedule of annual minimum undiscounted lease payments under our leases as of December 31, 2019.

Rental expense charged to operations was $6.6 million, $9.8 million and $9.1 million for the years ended December 31, 2019, 2018 and 2017, respectively. As of December 31, 2019, we expect to receive aggregate payments totaling $1.4 million over the life of our noncancelable sublease of office space, expiring in 2026.

We also have other long-term contractual obligations consisting of long-term site service agreements with HFC, expiring in 2058 through 2066, for the provision of certain facility services and utility costs that relate to our assets located at HFC’s refinery facilities. We are presenting obligations for the full term of these agreements; however, the agreements can be terminated with 180 day notice if we cease to operate the applicable assets.

In addition, we have long-term contractual obligations associated with rights-of-way agreements, which have various termination dates through 2061. The related payments below include only obligations under the remaining non-cancelable terms of these agreements at December 31, 2019.

At December 31, 2019, these minimum future contractual obligations and other miscellaneous obligations having terms in excess of one year are as follows:

Employees, Retirement and Incentive Plans

Employees, Retirement and Incentive Plans

Direct support for our operations is provided by Holly Logistic Services, L.L.C., ("HLS"), an HFC subsidiary, which utilizes personnel employed by HFC who are dedicated to performing services for us. Their costs, including salaries, bonuses, payroll taxes, benefits and other direct costs, are charged to us monthly in accordance with an omnibus agreement that we have with HFC. These employees participate in the retirement and benefit plans of HFC. Our share of retirement and benefit plan costs was $7.3 million, $6.9 million and $5.9 million for the years ended December 31, 2019, 2018 and 2017, respectively. These costs include retirement costs of $3.4 million, $3.1 million and $2.7 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Under HLS’s secondment agreement with HFC (the “Secondment Agreement”), certain employees of HFC are seconded to HLS to provide operational and maintenance services for certain of our processing, refining, pipeline and tankage assets, and HLS reimburses HFC for its prorated portion of the wages, benefits, and other costs related to these employees.

We have a Long-Term Incentive Plan for employees and non-employee directors who perform services for us. The Long-Term Incentive Plan consists of four components: restricted or phantom units, performance units, unit options and unit appreciation rights. Our accounting policy for the recognition of compensation expense for awards with pro-rata vesting (a significant proportion of our awards) is to expense the costs ratably over the vesting periods. We account for forfeitures on an estimated basis.

As of December 31, 2019, we have two types of incentive-based awards outstanding, which are described below. The compensation cost charged against income was $2.5 million, $3.0 million and $2.7 million for the years ended December 31, 2019, 2018 and 2017, respectively. We currently purchase units in the open market instead of issuing new units for settlement of all unit awards

under our Long-Term Incentive Plan. As of December 31, 2019, 2,500,000 units were authorized to be granted under our Long-Term Incentive Plan, of which 1,113,537 have not yet been granted, assuming no forfeitures of the unvested units and full achievement of goals for the unvested performance units.

Restricted and Phantom Units

Under our Long-Term Incentive Plan, we grant restricted units to non-employee directors and phantom units to selected employees who perform services for us, with most awards vesting over a period of one to three years. We previously granted restricted units to selected employees who perform services for us, which vest over a period of three years. Although full ownership of the units does not transfer to the recipients until the units vest, the recipients have distribution rights on these units from the date of grant, and the recipients of the restricted units have voting rights on the restricted units from the date of grant.

The fair value of each restricted or phantom unit award is measured at the market price as of the date of grant and is amortized on a straight-line basis over the requisite service period for each separately vesting portion of the award.

A summary of restricted and phantom unit activity and changes during the year ended December 31, 2019, is presented below: 

Restricted and Phantom Units	Units		Weighted- Average Grant-Date Fair Value
Outstanding at January 1, 2019 (nonvested)	138,016		$	31.35
Granted	95,300		23.52
Vesting and transfer of common units to recipients	(64,732	)	31.96
Forfeited	(23,379	)	29.57
Outstanding at December 31, 2019 (nonvested)	145,205		$	26.22

The grant date fair values of restricted units that were vested and transferred to recipients during the years ended December 31, 2019, 2018 and 2017 were $2.1 million, $2.5 million and $2.0 million, respectively. As of December 31, 2019, there was $2.3 million of total unrecognized compensation expense related to unvested restricted and phantom unit grants, which is expected to be recognized over a weighted-average period of 1.6 years. For the years ended December 31, 2018 and 2017, the grant date price applied to the number of restricted units awarded was $29.30 and $35.59 respectively.

Performance Units

Under our Long-Term Incentive Plan, we grant performance units to selected executives who perform services for us. Performance units granted are payable in common units at the end of a three-year performance period based upon meeting certain criteria over the performance period. Under the terms of our performance unit grants, some awards are subject to the growth in our distributable cash flow per common unit over the performance period while other awards are subject to "financial performance" and "market performance." Financial performance is based on meeting certain earnings before interest, taxes, depreciation and amortization ("EBITDA") targets, while market performance is based on the relative standing of total unitholder return achieved by HEP compared to peer group companies. The number of units ultimately issued under these awards can range from 50% to 150% or 0% to 200%. As of December 31, 2019, estimated unit payouts for outstanding nonvested performance unit awards ranged between 100% and 150% of the target number of performance units granted.

Although common units are not transferred to the recipients until the performance units vest, the recipients have distribution rights with respect to the common units from the date of grant.

A summary of performance unit activity and changes for the year ended December 31, 2019, is presented below:

Performance Units	Units
Outstanding at January 1, 2019 (nonvested)	51,748
Granted	17,010
Vesting and transfer of common units to recipients	(10,113	)
Forfeited	(5,200	)
Outstanding at December 31, 2019 (nonvested)	53,445

The grant date fair values of performance units vested and transferred to recipients were $0.3 million, $0.1 million and $0.1 million for the years ended December 31, 2019, 2018 and 2017, respectively. Based on the weighted average fair value of performance units outstanding at December 31, 2019, of $1.6 million, there was $0.6 million of total unrecognized compensation expense related to nonvested performance units, which is expected to be recognized over a weighted-average period of 1.6 years.

During the year ended December 31, 2019, we paid $1.5 million for the purchase of our common units in the open market for the issuance and settlement of unit awards under our Long-Term Incentive Plan.

Leases

Leases [Abstract]

Leases

Leases

We adopted ASC 842 effective January 1, 2019, and elected to adopt using the modified retrospective transition method and practical expedients, both of which are provided as options by the standard and further defined in Note 1.

Lessee Accounting

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

As a lessee, we lease land, buildings, pipelines, transportation and other equipment to support our operations. These leases can be categorized into operating and finance leases. Operating leases are recorded in operating lease right-of-use assets and current and noncurrent operating lease liabilities on our consolidated balance sheet. Finance leases are included in properties and equipment, current finance lease liabilities and noncurrent finance lease liabilities on our consolidated balance sheet.

When renewal options are defined in a lease, our lease term includes an option to extend the lease when it is reasonably certain we will exercise that option. Leases with a term of 12 months or less are not recorded on our balance sheet, and lease expense is accounted for on a straight-line basis. In addition, as a lessee, we separate non-lease components that are identifiable and exclude them from the determination of net present value of lease payment obligations.

Our leases have remaining terms of 1 to 25 years, some of which include options to extend the leases for up to 10 years.

Lease Obligations

We have finance lease obligations related to vehicle leases with initial terms of 33 to 48 months. The total cost of assets under finance leases was $7.0 million and $5.8 million as of December 31, 2019 and December 31, 2018, respectively, with accumulated depreciation of $4.5 million and $4.3 million as of December 31, 2019 and December 31, 2018, respectively. We include depreciation of finance leases in depreciation and amortization in our consolidated statements of income.

In addition, we have a finance lease obligation related to a pipeline lease with an initial term of 10 years with one remaining subsequent renewal option for an additional 10 years. The right of use asset associated with this obligation was derecognized as discussed under the lessor accounting disclosures below.

Lessor Accounting

As discussed in Note 4, the majority of our contracts with customers meet the definition of a lease. See Note 4 for further discussion of the impact of adoption of this standard on our activities as a lessor.

Customer contracts that contain leases are generally classified as either operating leases, direct finance leases or sales-type leases. We consider inputs such as the lease term, fair value of the underlying asset and residual value of the underlying assets when assessing the classification.

Substantially all of the assets supporting contracts meeting the definition of a lease have long useful lives, and we believe these assets will continue to have value when the current agreements expire due to our risk management strategy for protecting the residual fair value of the underlying assets by performing ongoing maintenance during the lease term. HFC generally has the option to purchase assets located within HFC refinery boundaries, including refinery tankage, truck racks and refinery processing units, at fair market value when the related agreements expire.

One of our throughput agreements with HFC was renewed during the year ended December 31, 2019. Certain components of this agreement met the criteria of sales-type leases since the underlying assets are not expected to have an alternative use at the end of the lease term to anyone besides HFC. Under sales-type lease accounting, at the commencement date, the lessor recognizes a net investment in the lease and derecognizes the underlying assets with the difference recorded as gain or loss arising from the lease. Therefore, we recognized a gain on sales-type leases during the year ended December 31, 2019 composed of the following:

	(In thousands)
Net investment in leases	$	122,800
Properties and equipment, net	(15,031		)
Operating lease right-of-use assets, net	(72,603		)
Gain on sales-type leases	$	35,166

This sales-type lease transaction, including the related gain, was a non-cash transaction.

Lease income recognized was as follows:

	Years Ended December 31,
	2019		2018
	(In thousands)
Operating lease revenues	$	373,517	$	278,624
Direct financing lease interest income	$	2,082	$	2,108
Gain on sales-type leases	$	35,166	$	—
Sales-type lease interest income	$	3,340	$	—
Lease revenues relating to variable lease payments not included in measurement of the sales-type lease receivable	$	4,794	$	—

For our sales-type leases, we included customer obligations related to minimum volume requirements in guaranteed minimum lease payments. Portions of our minimum guaranteed pipeline tariffs for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. We recognized any billings for throughput volumes in excess of minimum volume requirements as variable lease payments, and these variable lease payments were recorded in lease revenues.

As discussed in Notes 1 and 4, prior to the adoption of ASC 842, contract consideration was bifurcated between operating lease and service revenues.

Annual minimum undiscounted lease payments under our leases were as follows as of December 31, 2019:

	Operating		Finance		Sales-type
Years Ending December 31,	(In thousands)
2020	$	310,941	$	2,112	$	9,501

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

When renewal options are defined in a lease, our lease term includes an option to extend the lease when it is reasonably certain we will exercise that option. Leases with a term of 12 months or less are not recorded on our balance sheet, and lease expense is accounted for on a straight-line basis. In addition, as a lessee, we separate non-lease components that are identifiable and exclude them from the determination of net present value of lease payment obligations.

Our leases have remaining terms of 1 to 25 years, some of which include options to extend the leases for up to 10 years.

Lease Obligations

We have finance lease obligations related to vehicle leases with initial terms of 33 to 48 months. The total cost of assets under finance leases was $7.0 million and $5.8 million as of December 31, 2019 and December 31, 2018, respectively, with accumulated depreciation of $4.5 million and $4.3 million as of December 31, 2019 and December 31, 2018, respectively. We include depreciation of finance leases in depreciation and amortization in our consolidated statements of income.

In addition, we have a finance lease obligation related to a pipeline lease with an initial term of 10 years with one remaining subsequent renewal option for an additional 10 years. The right of use asset associated with this obligation was derecognized as discussed under the lessor accounting disclosures below.

Lessor Accounting

As discussed in Note 4, the majority of our contracts with customers meet the definition of a lease. See Note 4 for further discussion of the impact of adoption of this standard on our activities as a lessor.

Customer contracts that contain leases are generally classified as either operating leases, direct finance leases or sales-type leases. We consider inputs such as the lease term, fair value of the underlying asset and residual value of the underlying assets when assessing the classification.

Substantially all of the assets supporting contracts meeting the definition of a lease have long useful lives, and we believe these assets will continue to have value when the current agreements expire due to our risk management strategy for protecting the residual fair value of the underlying assets by performing ongoing maintenance during the lease term. HFC generally has the option to purchase assets located within HFC refinery boundaries, including refinery tankage, truck racks and refinery processing units, at fair market value when the related agreements expire.

One of our throughput agreements with HFC was renewed during the year ended December 31, 2019. Certain components of this agreement met the criteria of sales-type leases since the underlying assets are not expected to have an alternative use at the end of the lease term to anyone besides HFC. Under sales-type lease accounting, at the commencement date, the lessor recognizes a net investment in the lease and derecognizes the underlying assets with the difference recorded as gain or loss arising from the lease. Therefore, we recognized a gain on sales-type leases during the year ended December 31, 2019 composed of the following:

	(In thousands)
Net investment in leases	$	122,800
Properties and equipment, net	(15,031		)
Operating lease right-of-use assets, net	(72,603		)
Gain on sales-type leases	$	35,166

This sales-type lease transaction, including the related gain, was a non-cash transaction.

Lease income recognized was as follows:

	Years Ended December 31,
	2019		2018
	(In thousands)
Operating lease revenues	$	373,517	$	278,624
Direct financing lease interest income	$	2,082	$	2,108
Gain on sales-type leases	$	35,166	$	—
Sales-type lease interest income	$	3,340	$	—
Lease revenues relating to variable lease payments not included in measurement of the sales-type lease receivable	$	4,794	$	—

For our sales-type leases, we included customer obligations related to minimum volume requirements in guaranteed minimum lease payments. Portions of our minimum guaranteed pipeline tariffs for assets subject to sales-type lease accounting are recorded as interest income with the remaining amounts recorded as a reduction in net investment in leases. We recognized any billings for throughput volumes in excess of minimum volume requirements as variable lease payments, and these variable lease payments were recorded in lease revenues.

As discussed in Notes 1 and 4, prior to the adoption of ASC 842, contract consideration was bifurcated between operating lease and service revenues.

Annual minimum undiscounted lease payments under our leases were as follows as of December 31, 2019:

We adopted ASC 842 effective January 1, 2019, and elected to adopt using the modified retrospective transition method and practical expedients, both of which are provided as options by the standard and further defined in Note 1.

Lessee Accounting

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

As a lessee, we lease land, buildings, pipelines, transportation and other equipment to support our operations. These leases can be categorized into operating and finance leases. Operating leases are recorded in operating lease right-of-use assets and current and noncurrent operating lease liabilities on our consolidated balance sheet. Finance leases are included in properties and equipment, current finance lease liabilities and noncurrent finance lease liabilities on our consolidated balance sheet.

When renewal options are defined in a lease, our lease term includes an option to extend the lease when it is reasonably certain we will exercise that option. Leases with a term of 12 months or less are not recorded on our balance sheet, and lease expense is accounted for on a straight-line basis.

Partners' Equity, Income Allocations and Cash Distributions

12 Months Ended

Dec. 31, 2019

Partners' Capital [Abstract]

Partners' Equity, Income Allocations and Cash Distributions

Partners’ Equity, Income Allocations and Cash Distributions

At December 31, 2019, HFC held 59,630,030 of our common units, constituting a 57% limited partner interest in us and held the non-economic general partner interest. Additionally, HFC owned all incentive distribution rights through October 31, 2017, when an agreement was reached with HEP Logistics, our general partner, impacting its equity interest in HEP including canceling these incentive distribution rights. See Note 1 for a description of this equity restructuring transaction.

Common Unit Private Placement

On January 25, 2018, we entered into a common unit purchase agreement in which certain purchasers agreed to purchase in a private placement 3,700,000 common units representing limited partnership interests, at a price of $29.73 per common unit. The private placement closed on February 6, 2018, and we received proceeds of approximately $110 million, which were used to repay indebtedness under our Credit Agreement. After this common unit issuance, HFC owned a 57% limited partner interest in us.

Continuous Offering Program

We have a continuous offering program under which we may issue and sell common units from time to time, representing limited partner interests, up to an aggregate gross sales amount of $200 million. As of December 31, 2019, HEP had issued 2,413,153 units under this program, providing $82.3 million in gross proceeds.

Allocations of Net Income

Net income attributable to the partners is allocated to the partners based on their weighted-average ownership percentage during the period.

Prior to the equity restructuring of the general partner interest owned by HEP Logistics described in Note 1 that occurred on October 31, 2017, net income attributable to the partners was allocated between limited partners and the general partner interest in accordance with the provisions of the partnership agreement. HEP net income allocated to the general partner included incentive distributions that were declared subsequent to quarter end. After incentive distributions and other priority allocations are allocated to the general partner, the remaining net income attributable to HEP was allocated to the partners based on their weighted-average ownership percentage during the period.

The following table presents the allocation of the general partner interest in net income for the periods presented below: 

	Years Ended December 31,
	2019		2018		2017
	(In thousands)
General partner interest in net income	$	—	$	—	$	919
General partner incentive distribution	—		—		34,128
Total general partner interest in net income	$	—	$	—	$	35,047

Cash Distributions

We consider regular cash distributions to unitholders on a quarterly basis, although there is no assurance as to the future cash distributions since they are dependent upon future earnings, cash flows, capital requirements, financial condition and other factors.

Within 45 days after the end of each quarter, we distribute all of our available cash (as defined in our partnership agreement) to unitholders of record on the applicable record date. The amount of available cash generally is all cash on hand at the end of the quarter; less the amount of cash reserves established by our general partner to provide for the proper conduct of our business, comply with applicable laws, any of our debt instruments, or other agreements; or provide funds for distributions to our unitholders and to our general partner for any one or more of the next four quarters; plus all cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter.

Prior to the equity restructuring transaction discussed in Note 1, we made distributions in the manner displayed in the table below. Subsequent to the financial restructuring, distributions are made equally to all common unit holders regardless of the amount of the distribution per unit.

	Total Quarterly Distribution	Marginal Percentage Interest in Distributions
	Target Amount	Unitholders	General Partner
Minimum quarterly distribution	$0.25	98%	2%
First target distribution	Up to $0.275	98%	2%
Second target distribution	above $0.275 up to $0.3125	85%	15%
Third target distribution	above $0.3125 up to $0.375	75%	25%
Thereafter	Above $0.375	50%	50%

On January 23, 2020, we announced our cash distribution for the fourth quarter of 2019 of $0.6725 per unit. The distribution was payable on all common units and was paid February 13, 2020, to all unitholders of record on February 3, 2020. However, HEP Logistics waived $2.5 million in limited partner cash distributions due to them as discussed in Note 1.

The following table presents the allocation of our regular quarterly cash distributions to the general and limited partners for the periods in which they apply. Our distributions are declared subsequent to quarter end; therefore, the amounts presented do not reflect distributions paid during the periods presented below.

	Years Ended December 31,

	(In thousands, except per unit data)
General partner interest in distribution	$	—	$	—	$	2,335

Cash distribution per unit applicable to limited partners	$	2.6875	$	2.6475	$	2.5475

As a master limited partnership, we distribute our available cash, which historically has exceeded our net income attributable to HEP because depreciation and amortization expense represents a non-cash charge against income. The result is a decline in our partners’ equity since our regular quarterly distributions have exceeded our quarterly net income attributable to HEP. Additionally, if the asset contributions and acquisitions from HFC had occurred while we were not a consolidated variable interest entity of HFC, our acquisition cost, in excess of HFC’s historical basis in the transferred assets, would have been recorded in our financial statements at the time of acquisition as increases to our properties and equipment and intangible assets instead of decreases to our partners’ equity.

Accounting Policies [Abstract]

Description of Business and Summary of Significant Accounting Policies

Description of Business and Summary of Significant Accounting Policies

Holly Energy Partners, L.P. (“HEP”) together with its consolidated subsidiaries, is a publicly held master limited partnership. As of December 31, 2019, HollyFrontier Corporation (“HFC”) and its subsidiaries own a 57% limited partner interest and the non-economic general partner interest in HEP. We commenced operations on July 13, 2004, upon the completion of our initial public offering. In these consolidated financial statements, the words “we,” “our,” “ours” and “us” refer to HEP unless the context otherwise indicates.

On October 31, 2017, we closed on an equity restructuring transaction with HEP Logistics Holdings, L.P. (“HEP Logistics”), a wholly-owned subsidiary of HFC and the general partner of HEP, pursuant to which the incentive distribution rights ("IDRs") held by HEP Logistics were canceled, and HEP Logistics' 2% general partner interest in HEP was converted into a non-economic general partner interest in HEP. In consideration, we issued 37,250,000 of our common units to HEP Logistics. In addition, HEP Logistics agreed to waive $2.5 million of limited partner cash distributions for each of twelve consecutive quarters beginning with the first quarter the units issued as consideration were eligible to receive distributions. This waiver of limited partner cash distributions will expire after the cash distribution for the second quarter of 2020, which will be made during the third quarter of 2020. As a result of this transaction, no distributions were made on the general partner interest after October 31, 2017.

On January 25, 2018, we entered into a common unit purchase agreement in which certain purchasers agreed to purchase in a private placement 3,700,000 common units representing limited partner interests, at a price of $29.73 per common unit. The private placement closed on February 6, 2018, and we received proceeds of approximately $110 million, which were used to repay indebtedness under our revolving credit facility.

We own and operate petroleum product and crude oil pipelines, terminal, tankage and loading rack facilities and refinery processing units that support the refining and marketing operations of HFC and other refineries in the Mid-Continent, Southwest and Northwest regions of the United States and Delek US Holdings, Inc.’s (“Delek”) refinery in Big Spring, Texas. Additionally, we own a 75% interest in the UNEV Pipeline, LLC (“UNEV”), a 50% interest in Osage Pipe Line Company, LLC (“Osage”), a 50% interest in Cheyenne Pipeline LLC, and a 50% interest in Cushing Connect Pipeline & Terminal LLC.

We operate in two reportable segments, a Pipelines and Terminals segment and a Refinery Processing Unit segment. Disclosures around these segments are discussed in Note 16.

Our Pipelines and Terminals segment consists of:

• 26 main pipeline segments

• Crude gathering networks in Texas and New Mexico

• 10 refined product terminals

• 1 crude terminal

• 31,800 track feet of rail storage located at two facilities

• 7 locations with truck and/or rail racks

• Tankage at all six of HFC's refining facility locations

Our Refinery Processing Unit segment consists of five refinery processing units at two of HFC's refining facility locations.

We generate revenues by charging tariffs for transporting petroleum products and crude oil through our pipelines, by charging fees for terminalling and storing refined products and other hydrocarbons, providing other services at our storage tanks and terminals and by charging fees for processing hydrocarbon feedstocks through our refinery processing units. We do not take ownership of products that we transport, terminal, store or process, and therefore, we are not exposed directly to changes in commodity prices.

Principles of Consolidation and Common Control Transactions

The consolidated financial statements include our accounts, our Predecessor's (defined below) and those of subsidiaries and joint ventures that we control. All significant intercompany transactions and balances have been eliminated. Certain prior period balances have been reclassified for consistency with current year presentation.

Most of our acquisitions from HFC occurred while we were a consolidated variable interest entity of HFC. Therefore, as an entity under common control with HFC, we recorded these acquisitions on our balance sheets at HFC's historical basis instead of our purchase price or fair value. U.S. generally accepted accounting principles ("GAAP") require transfers of a business between entities under common control to be accounted for as though the transfer occurred as of the beginning of the period of transfer,

and prior period financial statements and financial information are retrospectively adjusted to include the historical results and assets of the acquisitions from HFC for all periods presented prior to the effective dates of each acquisition. We refer to the historical results of the acquisitions prior to their respective acquisition dates as those of our "Predecessor." Many of these transactions are cash purchases and do not involve the issuance of equity; however, GAAP requires the retrospective adjustment of financial statements. Therefore, in such transactions, the prior year balance sheet includes as equity the amount of cost incurred by HFC to that date.

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 and Cash Equivalents

For purposes of the statements of cash flows, we consider all highly liquid investments with maturities of three months or less at the time of purchase to be cash equivalents. The carrying amounts reported on the balance sheets approximate fair value due to the short-term maturity of these instruments.

Accounts Receivable

The majority of the accounts receivable are due from affiliates of HFC or independent 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, may be required. Credit losses are charged to income when accounts are deemed uncollectible and historically have been minimal.

Properties and Equipment

Properties and equipment are stated at cost. Properties and equipment acquired from HFC while under common control of HFC are stated at HFC's historical basis. Depreciation is provided by the straight-line method over the estimated useful lives of the assets, primarily 15 to 25 years for terminal facilities and tankage, 25 to 30 years for pipelines, 25 years for refinery processing units and 3 to 10 years for corporate and other assets. We depreciate assets acquired under capital leases over the lesser of the lease term or the economic life of the assets. Maintenance, repairs and minor replacements are expensed as incurred. Costs of replacements constituting improvements are capitalized.

Intangible Assets

Intangible assets include transportation agreements and acquired customer relationship intangible assets. Intangible assets are stated at acquisition date fair value and are being amortized over their useful lives using the straight-line method.

Goodwill and Long-Lived Assets

Goodwill represents the excess of our cost of an acquired business over the fair value of the assets acquired, less liabilities assumed. Goodwill is not amortized. We test goodwill at the reporting unit level for impairment annually and between annual tests if events or changes in circumstances indicate the carrying amount may exceed fair value. Our goodwill impairment testing first entails a comparison of our reporting unit fair values relative to their respective carrying values, including goodwill. If carrying value exceeds fair value for a reporting unit, we measure goodwill impairment as the excess of the carrying amount of reporting unit goodwill over the implied fair value of that goodwill based on estimates of the fair value of all assets and liabilities in the reporting unit.

In 2019, we assessed qualitative factors such as macroeconomic conditions, industry considerations, cost factors, and reporting unit financial performance and determined it was not more likely than not that the fair value of our reporting units were less than the respective carrying value. Therefore, in accordance with GAAP, further testing was not required. In 2018, we used the present value of the expected future net cash flows and market multiple analyses to determine the estimated fair values of the reporting units. The impairment test requires the use of projections, estimates and assumptions as to the future performance of our operations. Actual results could differ from projections resulting in revisions to our assumptions, and if required, could result in the recognition of an impairment loss.

We evaluate long-lived assets, including finite intangible 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.

There have been no impairments to goodwill or our long-lived assets through December 31, 2019.

Investment in Equity Method Investments

We account for our interests in noncontrolling joint venture interests using the equity method of accounting, whereby we record our pro-rata share of earnings of these companies, and contributions to and distributions from the joint ventures as adjustments to our investment balances. The difference between the cost of an investment and our proportionate share of the underlying equity in net assets recorded on the investee's books is allocated to the various assets and liabilities of the equity method investment.

The following table summarizes our recorded investments compared to our share of underlying equity for each investee. We are amortizing the differences as adjustments to our pro-rata share of earnings over the useful lives of the underlying assets of these joint ventures.

	Balance at December 31, 2019
	Underlying Equity		Recorded Investment Balance		Difference
	(in thousands)
Equity Method Investments
Osage Pipe Line Company, LLC	$	9,664	$	39,277	$	(29,613	)

Cushing Connect Terminal Holdings LLC	51,019		37,084		13,935

Cheyenne Pipeline LLC	29,358		43,357		(13,999		)
Total	$	39,322	$	83,840	$	(44,518	)

Asset Retirement Obligations

We record legal obligations associated with the retirement of certain of our long-lived assets that result from the acquisition, construction, development and/or the normal operation of our long-lived assets. The fair value of the estimated cost to retire a tangible long-lived asset is recorded in the period in which the liability is incurred and when a reasonable estimate of the fair value of the liability can be made. For our pipeline assets, the right-of-way agreements typically do not require the dismantling, removal and reclamation of the right-of-way upon cessation of the pipeline service. Additionally, management is unable to predict when, or if, our pipelines and related facilities would become obsolete and require decommissioning. Accordingly, we have recorded no liability or corresponding asset related to an asset retirement obligation for the majority of our pipelines as both the amounts and timing of such potential future costs are indeterminable. For our remaining assets, at December 31, 2019 and 2018, we have asset retirement obligations of $7.7 million and $8.9 million, respectively, that are recorded under “Other long-term liabilities” in our consolidated balance sheets.

Class B Unit

Under the terms of the transaction to acquire HFC's 75% interest in UNEV, we issued HFC a Class B unit comprising a noncontrolling equity interest in a wholly-owned subsidiary subject to redemption to the extent that HFC is entitled to a 50% interest in our share of annual UNEV earnings before interest, income taxes, depreciation, and amortization above $30 million beginning July 1, 2016, and ending in June 2032, subject to certain limitations. Such contingent redemption payments are limited to the unredeemed value of the Class B Unit. However, to the extent earnings thresholds are not achieved, no redemption payments are required. No redemption payments have been required to date.

Contemporaneously with this transaction, HFC (our general partner) agreed to forego its right to incentive distributions of up to $1.25 million per quarter over twelve consecutive quarterly periods following the closing of the transaction and up to an additional four quarters if HFC's Woods Cross refinery expansion did not attain certain thresholds. HEP Logistics' waiver of its right to incentive distributions of $1.25 million per quarter ended with the distribution paid in the third quarter of 2016.

Pursuant to the terms of the transaction agreements, the Class B unit increases by the amount of each foregone incentive distribution and by a 7% factor compounded annually on the outstanding unredeemed balance through its expiration date. At our option, we may redeem, in whole or in part, the Class B unit at the current unredeemed value based on the calculation described. The Class B unit had a carrying value of 49.4 million at December 31, 2019, and 46.2 million at December 31, 2018.

Revenue Recognition

Revenues are generally recognized as products are shipped through our pipelines and terminals, feedstocks are processed through our refinery processing units or other services are rendered. The majority of our contracts with customers meet the definition of a lease since (1) performance of the contracts is dependent on specified property, plant, or equipment and (2) it is remote that one or more parties other than the customer will take more than a minor amount of the output associated with the specified property, plant, or equipment. Prior to the adoption of the new lease standard (see below), we bifurcated the consideration received between lease and service revenue. The new lease standard allows the election of a practical expedient whereby a lessor does not have to separate non-lease (service) components from lease components under certain conditions. The majority of our contracts meet these conditions, and we have made this election for those contracts. Under this practical expedient, we treat the combined components as a single performance obligation in accordance with Accounting Standards Codification (“ASC”) 606, which largely codified ASU 2014-09, if the non-lease (service) component is the dominant component. If the lease component is the dominant component, we treat the combined components as a lease in accordance with ASC 842, which largely codified ASU 2016-02.

See Note 4 for further discussion of revenue recognition.

Prior to the adoption of ASC 606 on January 1, 2018, billings to customers for their obligations under their quarterly minimum revenue commitments were recorded as deferred revenue liabilities if the customer had the right to receive future services for these billings. The revenue was recognized at the earlier of:

• the customer receiving the future services provided by these billings,

• the period in which the customer was contractually allowed to receive the services expired, or

• our determination that we would not be required to provide services within the allowed period.

We determined that we would not be required to provide services within the allowed period when, based on current and projected shipping levels, our pipeline systems would not have the necessary capacity to enable a customer to exceed its minimum volume levels to such a degree as to utilize the shortfall credit within its respective contractual shortfall make-up period.

We have additional revenues under an operating lease to a third party of an interest in the capacity of one of our pipelines.

We have other cost reimbursement provisions in our throughput / storage agreements providing that customers (including HFC) reimburse us for certain costs. Such reimbursements are recorded as revenue or deferred revenue depending on the nature of the cost. Deferred revenue is recognized over the remaining contractual term of the related throughput agreement.

Taxes billed and collected from our pipeline and terminal customers are recorded on a net basis with no effect on net income.

Environmental Costs

Environmental costs are expensed 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, time frame and extent of required remedial and clean-up activities and are subject to periodic adjustments based on currently available information.

Under the Omnibus Agreement and certain transportation agreements and purchase agreements with HFC, HFC has agreed to indemnify us, subject to certain monetary and time limitations, for environmental noncompliance and remediation liabilities associated with certain assets transferred to us from HFC occurring or existing prior to the date of such transfers. We have an

environmental agreement with Delek with respect to pre-closing environmental costs and liabilities relating to the pipelines and terminals acquired from Delek in 2005, under which Delek will indemnify us subject to certain monetary and time limitations. Environmental costs recoverable through insurance, indemnification agreements or other sources are included in other assets to the extent such recoveries are considered probable.

Income Tax

We are subject to the Texas margin tax that is based on our Texas sourced taxable margin. The tax is calculated by applying a tax rate to a base that considers both revenues and expenses and therefore has the characteristics of an income tax.

We are organized as a pass-through entity for federal income tax purposes. As a result, our partners are responsible for federal income taxes based on their respective share of taxable income.

Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under the partnership agreement.

Net Income per Limited Partners' Unit

Net income per unit applicable to the limited partners was computed using the two-class method since we had more than one class of participating securities during the period from January 1, 2017 through October 31, 2017.  The classes of participating securities during this period included common units, general partner units and IDRs. Due to the equity restructuring transaction described above, as of December 31, 2017, we had one class of security outstanding, common units. To the extent net income attributable to the partners exceeds or is less than cash distributions, this difference is allocated to the partners based on their weighted-average ownership percentage during the period, after consideration of any priority allocations of earnings. Other participating securities and dilutive securities are not significant.

Accounting Pronouncement Adopted During the Periods Presented

Goodwill Impairment Testing

In January 2017, Accounting Standard Update (“ASU”) 2017-04, “Simplifying the Test for Goodwill Impairment,” was issued amending the testing for goodwill impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under this standard, goodwill impairment is measured as the excess of the carrying amount of the reporting unit over the related fair value. We adopted this standard effective in the second quarter of 2019, and the adoption of this standard had no effect on our financial condition, results of operations or cash flows.

Leases

In February 2016, ASU No. 2016-02, “Leases” (“ASC 842”) was issued requiring leases to be measured and recognized as a lease liability, with a corresponding right-of-use asset on the balance sheet. We adopted this standard effective January 1, 2019, and we elected to adopt using the modified retrospective transition method, whereby comparative prior period financial information will not be restated and will continue to be reported under the lease accounting standard in effect during those periods. We also elected practical expedients provided by the new standard, including the package of practical expedients and the short-term lease recognition practical expedient, which allows an entity to not recognize on the balance sheet leases with a term of 12 months or less. Upon adoption of this standard, we recognized $78.4 million of lease liabilities and corresponding right-of-use assets on our consolidated balance sheet. See Notes 4 and 5 of Notes to the Consolidated Financial Statements for additional information on our lease policies.

Revenue Recognition

In May 2014, an accounting standard update was issued requiring revenue to be recognized when promised goods or services are transferred to customers in an amount that reflects the expected consideration for these goods or services. This standard had an effective date of January 1, 2018, and we accounted for the new guidance using the modified retrospective implementation method, whereby a cumulative effect adjustment was recorded to retained earnings as of the date of initial application. In preparing for adoption, we evaluated the terms, conditions and performance obligations under our existing contracts with customers. Furthermore, we implemented policies to comply with this new standard. See above and Note 4 for additional information on our revenue recognition policies.

Business Combinations

In December 2014, an accounting standard update was issued to provide new guidance on the definition of a business in relation to accounting for identifiable intangible assets in business combinations. This standard had an effective date of January 1, 2018, and had no effect on our financial condition, results of operations or cash flows.

Financial Assets and Liabilities

In January 2016, an accounting standard update was issued requiring changes in the accounting and disclosures for financial instruments. This standard was effective beginning with our 2018 reporting year and had no effect on our financial condition, results of operations or cash flows.

Accounting Pronouncements Not Yet Adopted

Credit Losses Measurement

In June 2016, ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” was issued requiring measurement of all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. This standard is effective January 1, 2020, and our preliminary review of historic and expected credit losses indicates the amount of expected credit losses upon adoption would not have a material impact on our financial condition, results of operations or cash flows.

Related Party Transactions

We serve HFC’s refineries under long-term pipeline, terminal and tankage throughput agreements, and refinery processing unit tolling agreements expiring from 2021 to 2036 and revenues from these agreements accounted for approximately 77% of our total revenues for the year ended December 31, 2019. Under these agreements, HFC agrees to transport, store, and process throughput volumes of refined product, crude oil and feedstocks on our pipelines, terminals, tankage, loading rack facilities and refinery processing units that result in minimum annual payments to us. These minimum annual payments or revenues are subject to annual rate adjustments on July 1st each year based on the Producer Price Index (“PPI”) or FERC index. As of December 31, 2019, these agreements with HFC require minimum annualized payments to us of $348.1 million.

If HFC fails to meet its minimum volume commitments under the agreements in any quarter, it will be required to pay us the amount of any shortfall in cash by the last day of the month following the end of the quarter. Under certain of these agreements, a shortfall payment may be applied as a credit in the following four quarters after its minimum obligations are met.

Under certain provisions of the Omnibus Agreement, we pay HFC an annual administrative fee (currently $2.6 million) for the provision by HFC or its affiliates of various general and administrative services to us. This fee does not include the salaries of personnel employed by HFC who perform services for us on behalf of HLS or the cost of their employee benefits, which are charged to us separately by HFC. Also, we reimburse HFC and its affiliates for direct expenses they incur on our behalf.

Related party transactions with HFC are as follows:

• Revenues received from HFC were $411.8 million, $397.8 million and $377.1 million for the years ended December 31, 2019, 2018 and 2017, respectively.

• HFC charged us general and administrative services under the Omnibus Agreement of $2.6 million for December 31, 2019 and $2.5 million for each of the years ended December 31, 2018 and 2017.

• We reimbursed HFC for costs of employees supporting our operations of $55.1 million, $51.7 million and $46.6 million for the years ended December 31, 2019, 2018 and 2017, respectively.

• HFC reimbursed us $13.9 million, $10.0 million and $7.2 million for the years ended December 31, 2019, 2018 and 2017, respectively, for expense and capital projects.

• We distributed $150.0 million and $146.8 million, in the years ended December 31, 2019 and 2018, respectively, to HFC as regular distributions on its common units and $130.7 million in the year ended December 31, 2017 to HFC as regular distributions on its common units and general partner interest, including general partner incentive distributions.

• Accounts receivable from HFC were $49.7 million and $46.8 million at December 31, 2019 and 2018, respectively.

• Accounts payable to HFC were $16.7 million and $14.2 million at December 31, 2019 and 2018, respectively.

• Revenues for the years ended December 31, 2019, 2018 and 2017 include $0.5 million, $3.1 million and $4.8 million, respectively, of shortfall payments billed to HFC in 2018, 2017 and 2016, respectively. Deferred revenue in the consolidated balance sheets at December 31, 2019 and 2018, includes $0.5 million and $1.7 million, respectively, relating to certain shortfall billings to HFC.

• We received direct financing lease payments from HFC for use of our Artesia and Tulsa railyards of $2.1 million, $2.0 million and $0.5 million for the years ended December 31, 2019, 2018 and 2017, respectively.

• We recorded a gain on sales-type leases with HFC of $35.2 million during the year ended December 31, 2019, and we received sales-type lease payments of $4.8 million from HFC that were not included in revenues for the year ended December 31, 2019.

•

On October 31, 2017, we closed on an equity restructuring transaction with HEP Logistics, a wholly-owned subsidiary of HFC and the general partner of HEP, pursuant to which the incentive distribution rights held by HEP Logistics were canceled, and HEP Logistics' 2% general partner interest in HEP was converted into a non-economic general partner interest in HEP. In consideration, we issued 37,250,000 of our common units to HEP Logistics. In addition, HEP Logistics agreed to waive $2.5 million of limited partner cash distributions for each of twelve consecutive quarters beginning with the first quarter the units issued as consideration were eligible to receive distributions. This waiver of limited partner cash distributions will expire after the cash distribution for the second quarter of 2020, which will be made during the third quarter of 2020.

Intangible Assets

Intangible Assets

Intangible assets include transportation agreements and customer relationships that represent a portion of the total purchase price of certain assets acquired from Delek in 2005, from HFC in 2008 prior to HEP becoming a consolidated VIE of HFC, from Plains in 2017, and from other minor acquisitions in 2018.

The carrying amounts of our intangible assets are as follows:

	Useful Life	December 31, 2019		December 31, 2018
		(In thousands)
Delek transportation agreement	30 years	$	59,933	$	59,933
HFC transportation agreements	10-15 years	75,131		75,131
Customer relationships	10 years	69,683		69,683
Other	20 years	50		50
		204,797		204,797
Less accumulated amortization		103,475		89,468
		$	101,322	$	115,329

Amortization expense was $14.0 million, $14.5 million and $7.6 million for the years ending December 31, 2019, 2018 and 2017, respectively. We estimate amortization expense to be $14.0 million for each of the next three years and $9.9 million in 2023 and $9.1 million in 2024.

We have additional transportation agreements with HFC resulting from historical transactions consisting of pipeline, terminal and tankage assets contributed to us or acquired from HFC. These transactions occurred while we were a consolidated variable interest entity of HFC; therefore, our basis in these agreements is zero and does not reflect a step-up in basis to fair value.

We adopted the new revenue recognition standard (see Note 1) using the modified retrospective method, whereby the cumulative effect of applying the new standard was recorded as an adjustment to the opening balance of partners’ equity as well as the carrying amounts of assets and liabilities as of January 1, 2018, which had no impact on our cash flows. The following table reflects the cumulative effect of adoption as of January 1, 2018:

Several of our contracts include incentive or reduced tariffs once a certain quarterly volume is met. Revenue from the variable element of these transactions is recognized based on the actual volumes shipped as it relates specifically to rendering the services during the applicable quarter.

The majority of our long-term transportation contracts specify minimum volume requirements, whereby, we bill a customer for a minimum level of shipments in the event a customer ships below their contractual requirements. If there are no future performance obligations, we will recognize these deficiency payments in revenue.

In certain of these throughput agreements, a customer may later utilize such shortfall billings as credit towards future volume shipments in excess of its minimum levels within its respective contractual shortfall make-up period. Such amounts represent an obligation to perform future services, which may be initially deferred and later recognized as revenue based on estimated future shipping levels, including the likelihood of a customer’s ability to utilize such amounts prior to the end of the contractual shortfall make-up period. We recognize these deficiency payments in revenue when we do not expect we will be required to satisfy these performance obligations in the future based on the pattern of rights exercised by the customer. During the twelve months ended December 31, 2019, 2018 and 2017, we recognized $16.0 million, $17.6 million and $11.9 million, respectively, of these deficiency payments in revenue, of which $0.6 million, $3.3 million and $5.6 million, respectively, related to deficiency payments billed in prior periods. As of December 31, 2019, deferred revenue reflected in our consolidated balance sheet related to shortfalls billed was $0.7 million.

A contract liability exists when an entity is obligated to perform future services to a customer for which the entity has received consideration. Since HEP may be required to perform future services for these deficiency payments received, the deferred revenues on our balance sheet as of December 31, 2019 were considered contract liabilities. A contract asset exists when an entity has a right to consideration in exchange for goods or services transferred to a customer. Our consolidated balance sheet as of December 31, 2019, included the contract assets and liabilities in the table below.

	December 31, 2019			December 31, 2018
	(In thousands)
Contract assets	$	5,675		$	1,818
Contract liabilities	$	(650	)	$	(1,821	)

The contract assets and liabilities include both lease and service components. We recognized $0.6 million of revenue that was previously included in contract liability as of December 31, 2018, during the twelve months ended December 31, 2019. During the twelve months ended December 31, 2018, we recognized $2.7 million that was previously included in contract liability as of January 1, 2018. During the twelve months ended December 31, 2019 and 2018, we also recognized $3.9 million and $1.8 million respectively, of revenue included in contract assets at December 31, 2019.

As of December 31, 2019, we expect to recognize 2.4 billion in revenue related to our unfulfilled performance obligations under the terms of our long-term throughput agreements and operating leases expiring in 2020 through 2036. These agreements provide

for changes in the minimum revenue guarantees annually for increases or decreases in the Producer Price Index (“PPI”) or Federal Energy Regulatory Commission (“FERC”) index, with certain contracts having provisions that limit the level of the rate increases or decreases. We expect to recognize revenue for these unfulfilled performance obligations as shown in the table below (amounts shown in table include both service and lease revenues):

2021	359
2022	331
2023	294

Investment in Joint Venture

On October 2, 2019, HEP Cushing LLC (“HEP Cushing”), a wholly-owned subsidiary of HEP, and Plains Marketing, L.P., a wholly-owned subsidiary of Plains, formed a 50/50 joint venture, Cushing Connect Pipeline & Terminal LLC (the “Cushing Connect Joint Venture”), for (i) the development and construction of a new 160,000 barrel per day common carrier crude oil pipeline (the “Cushing Connect Pipeline”) that will connect the Cushing, Oklahoma crude oil hub to the Tulsa, Oklahoma refining complex owned by a subsidiary of HFC and (ii) the ownership and operation of 1.5 million barrels of crude oil storage in Cushing, Oklahoma (the “Cushing Connect JV Terminal”). The Cushing Connect JV Terminal is expected to be placed in service during the second quarter of 2020, and the Cushing Connect Pipeline is expected to be placed in service during the first quarter of 2021. Long-term commercial agreements have been entered into to support the Cushing Connect Joint Venture assets.

The Cushing Connect Joint Venture has contracted with an affiliate of HEP to manage the construction and operation of the Cushing Connect Pipeline and with an affiliate of Plains to manage the operation of the Cushing Connect JV Terminal. The total Cushing Connect Joint Venture investment will generally be shared equally among HEP and Plains, and HEP estimates its share of the cost of the Cushing Connect JV Terminal contributed by Plains and Cushing Connect Pipeline construction costs are approximately $65 million. However, any Cushing Connect Pipeline construction costs exceeding 10% of the budget are borne solely by us.

The Cushing Connect Joint Venture legal entities are variable interest entities ("VIEs") as defined under GAAP. A VIE is a legal entity if it has any one of the following characteristics: (i) the entity does not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support; (ii) the at risk equity holders, as a group, lack the characteristics of a controlling financial interest; or (iii) the entity is structured with non-substantive voting rights. The Cushing Connect Joint Venture legal entities do not have sufficient equity at risk to finance their activities without additional financial support. Since HEP is constructing and will operate the Cushing Connect Pipeline, HEP has more ability to direct the activities that most significantly impact the financial performance of the Cushing Connect Joint Venture and Cushing Connect Pipeline legal entities (collectively, the "Cushing Connect VIEs"). Therefore, HEP consolidates the Cushing Connect VIEs.

We do not have the ability to direct the activities that most significantly impact the Cushing Connect JV Terminal legal entity, and therefore, we account for our interest in the Cushing Connect JV Terminal legal entity using the equity method of accounting.

With the exception of the assets of HEP Cushing, creditors of the Cushing Connect Joint Venture legal entities have no recourse to our assets. Any recourse to HEP Cushing would be limited to the extent of HEP Cushing's assets, which other than its investment in Cushing Connect Joint Venture, are not significant. Furthermore, our creditors have no recourse to the assets of the Cushing Connect Joint Venture legal entities.

Acquisitions

SLC Pipeline and Frontier Aspen

On October 31, 2017, we acquired the remaining 75% interest in SLC Pipeline LLC ("SLC Pipeline") and the remaining 50% interest in Frontier Aspen LLC ("Frontier Aspen") from subsidiaries of Plains All American Pipeline, L.P. (“Plains”), for cash consideration of $250 million. Prior to this acquisition, we held noncontrolling interests of 25% of SLC Pipeline and 50% of Frontier Aspen. As a result of the acquisitions, SLC Pipeline and Frontier Aspen are wholly-owned subsidiaries of HEP.

These acquisitions were accounted for as a business combination achieved in stages. Our preexisting equity method investments in SLC Pipeline and Frontier Aspen were remeasured at an acquisition date fair value of $112 million since we now have a controlling interest, and we recognized a gain on the remeasurement in the fourth quarter of 2017 of $36.3 million. The fair value of our preexisting equity method investments in SLC Pipeline and Frontier Aspen was estimated using Level 3 Inputs under the income method for these entities, adjusted for lack of control and marketability.

The total consideration of $363.8 million, consisting of cash consideration of $250 million, working capital adjustments of $1.8 million and the fair value of our preexisting equity method investments in SLC Pipeline and Frontier Aspen of $112 million, was allocated to the acquisition date fair value of assets and liabilities acquired as of the October 31, 2017 acquisition date, with the excess purchase price recorded as goodwill.

The following summarizes the final estimated value of assets and liabilities acquired:

	(in thousands)
Cash and cash equivalents	$	4,609
Accounts receivable	5,164
Prepaid and other current assets	8
Properties and equipment	275,061
Intangible assets	70,182
Goodwill	13,845
Accounts payable	(3,598		)
Accrued property taxes	(1,438		)
Net assets acquired	$	363,833

Our consolidated financial and operating results reflect the SLC Pipeline and Frontier Aspen operations beginning November 1, 2017. Our results of operations for the year ended December 31, 2017 included revenues of $7.9 million and net income of $4.1 million, excluding the $36.3 million remeasurement gain as of the acquisition date discussed above, for the period from November 1, 2017 through December 31, 2017.

SLC Pipeline is the owner of a 95-mile crude pipeline that transports crude oil into the Salt Lake City area from the Utah terminal of the Frontier Pipeline (defined below) and from Wahsatch Station. Frontier Aspen is the owner of a 289-mile crude pipeline from Casper, Wyoming to Frontier Station, Utah (the "Frontier Pipeline") that supplies Canadian and Rocky Mountain crudes to Salt Lake City area refiners through a connection to the SLC Pipeline.

The following unaudited pro forma financial information combines the historical operations of HEP, SLC Pipeline and Frontier Aspen as if the acquisition had occurred on January 1, 2017:

	Years Ended December 31,
	2017
Revenues	$	489,382
Net income attributable to the partners	$	161,900

The unaudited pro forma net income attributable to the partners reflects the following adjustments:

(1) To retrospectively reflect depreciation and amortization of intangible assets based on the preliminary fair value of the assets as if that fair value had been reflected January 1, 2017;

(2) To eliminate HEP's equity income previously recorded on its equity method investments in SLC Pipeline and Frontier Aspen; and

(3)

To eliminate the remeasurement gain on preexisting equity interests in SLC Pipeline and Frontier Aspen.

Segment Reporting [Abstract]

Operating Segments

Operating Segments

Our operations are organized into two reportable operating segments: pipelines and terminals, and refinery processing units. These segments adhere to the accounting polices used for our consolidated financial statements. For a discussion of these accounting policies and a summary of our reportable operating segments' assets and derivation of revenue, see Note 1.

Pipelines and terminals have been aggregated as one reportable segment as both pipelines and terminals (1) have similar economic characteristics, (2) similarly provide logistics services of transportation and storage of petroleum products, (3) similarly support the petroleum refining business, including distribution of its products, (4) have principally the same customers and (5) are subject to similar regulatory requirements.

We evaluate the performance of each segment based on its respective operating income. Certain general and administrative expenses and interest and financing costs are excluded from segment operating income as they are not directly attributable to a specific reportable segment. Identifiable assets are those used by the segment, whereas other assets are principally equity method investments, cash, deposits and other assets that are not associated with a specific reportable segment.
