The preparation of our financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) and in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

We are an energy business focused on crude oil, natural gas, intermediate and refined products pipeline and storage activities and wholesale marketing, terminalling and offloading activities as well as water disposal and recycling. Management reviews operating results in four reportable segments: (i) gathering and processing; (ii) wholesale marketing and terminalling; (iii) storage and transportation; and (iv) investments in pipeline joint ventures.

•The wholesale marketing and terminalling segment provides marketing services for the refined products output of the Delek Holdings' refineries, engages in wholesale activity at our terminals and terminals owned by third parties, whereby we purchase light product for sale and exchange to third parties, and provides terminalling services at our refined products terminals to independent third parties and Delek Holdings.

During the fourth quarter 2022, we realigned our reportable segments for financial reporting purposes to reflect changes in the manner in which our chief operating decision maker ("CODM") assesses financial information for decision-making purposes. The primary change in our segmentation as compared to prior presentations is that our pipeline operations are now viewed separately from our storage and transportation segment because of the integral nature of the pipeline operations in relation to our expanded gathering operations, and certain legacy gathering activities and operations are now managed as part of the Gathering and Processing segment. Additionally, we are now segregating out certain non-segment specific costs and expenses and, when applicable, immaterial operating segments that may not fit into our existing reportable segments as Corporate and Other activities. While this reporting change did not change our consolidated results, segment data for previous years has been restated and is consistent with the current year presentation throughout the financial statements and the accompanying notes. The CODM evaluates performance based upon earnings before interest, taxes, depreciation and amortization ("EBITDA"). We define EBITDA for any period as net income (loss) to add back interest expense, income tax expense (benefit), depreciation and amortization (including amortization of customer contract intangible assets, which is included as a component of net revenues in our accompanying consolidated statements of income and comprehensive income). Segment reporting is discussed in more detail in Note 15.

Accounts receivable primarily consists of trade receivables generated in the ordinary course of business. We perform on-going credit evaluations of our customers and generally do not require collateral on accounts receivable. All accounts receivable amounts are considered to be fully collectible. Accordingly, no allowance for doubtful accounts has been established as of December 31, 2022 and 2021. Delek Holdings accounted for approximately 32.8% of the consolidated accounts receivable balance as of December 31, 2022. One third-party customer accounted for approximately 33.1% and 47.4% of the consolidated accounts receivable balance as of December 31, 2022 and December 31, 2021, respectively.

Property, plant and equipment primarily consists of crude oil pipelines, tanks, terminals and gathering systems, and trucking assets. Property and equipment is stated at the lower of historical cost less accumulated depreciation, or fair value, if impaired. Assets acquired in conjunction with business acquisitions are recorded at estimated fair market value in accordance with the purchase method of accounting as prescribed in Accounting Standards Codification ("ASC") 805, Business Combinations ("ASC 805"). Acquisitions of net assets that do not constitute a business are accounted for by allocating the cost of the acquisition to individual assets acquired and liabilities assumed on a relative fair value basis and shall not give rise to goodwill as prescribed in ASC 805.

Other intangible assets acquired in a business combination and determined to be finite-lived are amortized over their respective estimated useful lives. The finite-lived intangible assets are amortized on straight-line basis over the estimated useful lives of 8 to 35 years. The amortization expense, with the exception of the marketing contract intangible, is included in depreciation and amortization on the accompanying consolidated statements of income. The marketing contract intangible is amortized on a straight-line basis over a 20-year period as a component of net revenues from affiliates. Acquired intangible assets determined to have an indefinite useful life are not amortized, but are instead tested for impairment in connection with our evaluation of long-lived assets as events and circumstances indicate that the asset might be impaired.

Property, plant and equipment and intangibles are evaluated for impairment whenever indicators of impairment exist. In accordance with ASC 360, Property, Plant and Equipment and ASC 350, Intangibles - Goodwill and Other, we evaluate the realizability of these long-lived assets as events occur that might indicate potential impairment. In doing so, we assess whether the carrying amount of the asset is recoverable by estimating the sum of the future cash flows expected to result from the use of the asset, undiscounted and without interest charges. If the carrying amount is more than the recoverable amount, an impairment charge must be recognized based on the fair value of the asset.

Goodwill in an acquisition represents the excess of the aggregate purchase price over the fair value of the identifiable net assets. Goodwill is reviewed at least annually during the fourth quarter for impairment, or more frequently if indicators of impairment exist, such as disruptions in our business, unexpected significant declines in operating results or a sustained market capitalization decline. Goodwill is evaluated for impairment by comparing the carrying amount of the reporting unit to its estimated fair value. Goodwill impairment charge is recognized for the amount that the carrying amount of a reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. In assessing the recoverability of goodwill, assumptions are made with respect to future business conditions and estimated expected future cash flows to determine the fair value of a reporting unit.

We recognize and measure the assets acquired and liabilities assumed in a business combination based on their estimated fair values at the acquisition date in accordance with the provisions of ASC 805. Any excess or surplus of the purchase consideration when compared to the fair value of the net tangible assets acquired, if any, is recorded as goodwill or gain from a bargain purchase. The fair value of assets and liabilities as of the acquisition date are often estimated using a combination of approaches, including the income approach, which requires us to project future cash flows and apply an appropriate discount rate; the cost approach, which requires estimates of replacement costs and depreciation and obsolescence estimates; and the market approach which uses market data and adjusts for entity-specific differences. We use all available information to make these fair value determinations and engage third-party consultants for valuation assistance. The estimates used in determining fair values are based on assumptions believed to be reasonable but which are inherently uncertain. Accordingly, actual results may differ materially from the projected results used to determine fair value.

For equity investments that are not required to be consolidated under the variable or voting interest model, we evaluate the level of influence we are able to exercise over an entity’s operations to determine whether to use the equity method of accounting. Our judgment regarding the level of influence over an equity method investment includes considering key factors such as our ownership interest, participation in policy-making and other significant decisions and material intercompany transactions. Equity investments for which we determine we have significant influence

are accounted for as equity method investments. Amounts recognized for equity method investments are included in equity method investments in our consolidated balance sheets and adjusted for our share of the net earnings and losses of the investee, dividends received and cash distributions from the investee, which are separately stated in our consolidated statements of income and comprehensive income and our consolidated statements of cash flows. The carrying value of each equity method investment is evaluated for impairment when conditions exist that indicate it is more likely than not that an impairment may have occurred, which may include the loss of a key contract, lack of sustained earnings or a deterioration of market conditions, among others. When impairment triggers are present, the fair value of the equity method investment is estimated using the income approach and the market approach. The income approach utilizes a discounted cash flow model incorporating management’s expectations of the investee’s future revenue (including the throughput barrel per day sold and related reduced tariff rates), operating expenses and earnings before interest, taxes, depreciation and amortization, capital expenditures and an anticipated tax rate (“EBITDA”), the estimated long term growth rate and weighted average cost of capital (“WACC”) as the discount rate. The market approach uses estimated EBITDA multiples for guideline comparable companies to estimate the fair value of the equity method investment. An impairment loss is recorded in earnings in the current period if a decline in the value of an equity method investment is determined to be other than temporary. There were no impairment losses recorded on equity method investments for the years ended December 31, 2022, 2021 or 2020 Equity method investments are reported as part of the investments in pipeline joint ventures segment. See Note 14 for further information on our equity method investments.

It is our policy to accrue environmental and clean-up related costs of a non-capital nature when it is both probable that a liability has been incurred and the amount can be reasonably estimated. Environmental liabilities represent the current estimated costs to investigate and remediate contamination at sites where we have environmental exposure. This estimate is based on assessments of the extent of the contamination, the selected remediation technology and review of applicable environmental regulations, typically considering estimated activities and costs for 15 years, and up to 30 years if a longer period is believed reasonably necessary. Such estimates may require judgment with respect to costs, time frame and extent of required remedial and clean-up activities. Accruals for estimated costs from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study and include, but are not limited to, costs to perform remedial actions and costs of machinery and equipment that are dedicated to the remedial actions and that do not have an alternative use. Such accruals are adjusted as further information develops or circumstances change. We discount environmental liabilities to their present value if payments are fixed or reliably determinable. Expenditures for equipment necessary for environmental issues relating to ongoing operations are capitalized. Estimated recoveries of costs from other parties are recorded on an undiscounted basis as assets when their realization is deemed probable. See Note 17 for further information on crude oil releases impacting our properties and related accruals.

We recognize liabilities which represent the fair value of a legal obligation to perform asset retirement activities, including those that are conditional on a future event, when the amount can be reasonably estimated. These obligations are related to the required cleanout of our pipelines and terminal tanks and removal of certain above-grade portions of our pipelines situated on right-of-way property.

Service, Product and Lease Revenues. Revenues for products sold are generally recognized upon delivery of product, which is when title and control of the product is transferred. Transaction prices for these products are typically at market rates for the product at the time of delivery. Service revenues are recognized as crude oil, intermediate and refined products are shipped through, delivered by or stored in our pipelines, trucks, terminals and storage facility assets, as applicable. We do not recognize product revenues for these services, as the product does not represent a promised good in the context of ASC 606, Revenue from Contracts with Customers ("ASC 606"). All service revenues are based on regulated tariff rates or contractual rates. Payment terms require customers to pay shortly after delivery and do not contain significant financing components.

Certain agreements for gathering, transportation, storage, terminalling, and offloading with Delek Holdings were considered operating leases under ASC 840, Leases ("ASC 840"). As part of the adoption of ASC 842, we applied the permitted practical expedient to not separate lease and non-lease components under the predominance principle to designated asset classes associated with the provision of logistics services. We have determined that the predominant component of the related agreements currently in effect is the lease component. Therefore, the combined component is accounted for under the applicable lease accounting guidance. Refer to Note 5 for further information.

Up-Front payments to Customers. We record up-front payments to customers in accordance with ASC 606. We evaluate the nature of each payment, the rights and obligations under the related contract, and whether the payment meets the definition of an asset. When an asset is recognized for an up-front payment to a customer, the asset is amortized, as a reduction of revenue, in a manner that reflects the pattern and period over which the asset is expected to provide benefit.

Revenues Related to Reimbursements. In addition to the agreements noted above, we have cost reimbursement provisions in certain of our agreements with Delek Holdings that provide for reimbursement to the Partnership for certain costs, including certain capital expenditures. Such reimbursements are recorded in other long-term liabilities and are amortized to revenue over the life of the underlying revenue agreement corresponding to the asset.

Cost of materials and other includes (i) all costs of purchased refined products, additives and related transportation of such products, (ii) costs associated with the operation of our trucking assets, which primarily include allocated employee costs and other costs related to fuel, truck leases and repairs and maintenance, (iii) the cost of pipeline capacity leased from a third-party, and (iv) gains and losses related to our commodity hedging activities.

Operating expenses include the costs associated with the operation of owned terminals and pipelines and terminalling expense at third-party locations, excluding depreciation and amortization. These costs primarily include outside services, allocated employee costs, repairs and maintenance costs and energy and utility costs. Operating expenses related to the wholesale business are excluded from cost of sales because they primarily relate to costs associated with selling the products through our wholesale business.

Deferred financing costs are included in other non-current assets in the accompanying consolidated balance sheets and represent expenses related to issuing and amending our revolving credit facility. Deferred financing costs associated with our term loan facilities and are included as a reduction to the associated debt balance in the accompanying consolidated balance sheets. These costs represent expenses related to issuing our long-term debt and obtaining our lines of credit. These amounts are amortized ratably over the remaining term of the respective financing and are included in interest expense in the accompanying consolidated statements of income and comprehensive income.

We calculate the total lease expense for the entire noncancelable lease period, considering renewals for all periods for which it is reasonably certain to be exercised, and record lease expense on a straight-line basis in the accompanying consolidated statements of income. Accordingly, a lease liability is recognized for these leases and is calculated to be the present value of the fixed lease payments, as defined by ASC 842-20, using a discount rate based on our incremental borrowing rate. A corresponding right-of-use asset is recognized based on the lease liability and adjusted for certain costs and prepayments.

We are not a taxable entity for federal income tax purposes or the income taxes of those states that follow the federal income tax treatment of partnerships. Instead, for purposes of these income taxes, each partner of the Partnership is required to take into account its share of items of income, gain, loss and deduction in computing its federal and state income tax liabilities, regardless of whether cash distributions are made to such partner by the Partnership. The taxable income reportable to each partner takes into account differences between the tax basis and fair market value of our assets and financial reporting bases of assets and liabilities, the acquisition price of such partner's units and the taxable income allocation requirements under the Partnership's Second Amended and Restated Agreement of Limited Partnership, as amended (the "Partnership Agreement").

We are subject to income taxes in certain states that do not follow the federal tax treatment of partnerships. These taxes are accounted for under the provisions of ASC 740, Income Taxes ("ASC 740"). This statement generally requires the Partnership to record deferred income taxes for the differences between the book and tax bases of its assets and liabilities, which are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. Deferred income tax expense or benefit represents the net change during the year in our deferred income tax assets and liabilities, exclusive of the amounts held in other comprehensive income.

U.S. GAAP requires management to evaluate uncertain tax positions taken by the Partnership. The financial statement effects of a tax position are recognized when the position is more likely than not, based on the technical merits, to be sustained upon examination by the Internal Revenue Service. Management has analyzed the tax positions taken by the Partnership, and has concluded that there are no uncertain positions taken or expected to be taken. The Partnership is subject to routine audits by taxing jurisdictions.

Our general partner provides equity-based compensation to officers, directors and employees of our general partner or its affiliates, and certain consultants, affiliates of our general partner or other individuals who perform services for us, which may include unit options, restricted units, phantom units, unit appreciation rights, distribution equivalent rights, other unit-based awards and unit awards. The fair value of our phantom units is determined based on the closing market price of our common units on the grant date. The estimated fair value of our phantom units is amortized over the vesting period using the straight line method. Awards vest over one- to five-year service periods, unless such awards are amended in accordance with the 2012 Long-Term Incentive Plan (the "LTIP") (see Note 13). It is our practice to issue new units when phantom units vest.

Basic net income per unit applicable to limited partners is computed by dividing limited partners’ interest in net income by the weighted-average number of outstanding common units. Prior to August 13, 2020, we had more than one class of participating securities and used the two class method to calculate the net income per unit applicable to the limited partners. The classes of participating units prior to August 13, 2020 consisted of limited partner units, general partner units and IDRs. Pursuant to the IDR Restructuring Transaction, the IDRs were eliminated and the 2.0% general partner economic interest was converted to a non-economic general partner interest. Effective August 13, 2020, the common limited partner units are the only participating security for cash distributions. Refer to Notes 6 and 12 for further discussion.

In March 2020, the FASB issued an amendment which is intended to provide temporary optional expedients and exceptions to GAAP guidance on contracts, hedge accounting and other transactions affected by the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank rates. This guidance is effective for all entities at any time beginning on March 12, 2020 through December 31, 2022 and may be applied from the beginning of an interim period that includes the issuance date of the ASU. We adopted this guidance during 2022 and the adoption did not have a material impact on our business, financial condition or results of operations.
