Accounting Policies

Basis of Presentation

Our consolidated financial statements include the accounts of the Partnership and its subsidiaries as well as our Predecessors. All intercompany accounts and transactions have been eliminated. The financial statements of our Predecessors have been prepared from the separate records maintained by Delek and may not necessarily be indicative of the conditions that would have existed or the results of operations if our Predecessors had been operated as an unaffiliated entity. Our Predecessors did not record all revenues for intercompany gathering, pipeline transportation, terminalling and storage services. Transfers between entities under common control are accounted for as if the transfer occurred at the beginning of the period, and prior years are retrospectively adjusted to furnish comparative information. As an entity under common control with Delek, we record the assets that Delek has contributed to us on our balance sheet at Delek's historical basis instead of fair value.

We have evaluated subsequent events through the filing of this Annual Report on Form 10-K. Any material subsequent events that occurred during this time have been properly recognized or disclosed in our financial statements. The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) and in accordance with the rules and regulations of the Securities and Exchange Commission (“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.

Segment Reporting

We are an energy business focused on crude oil and refined product pipeline, storage, wholesale marketing and terminalling activities. Management reviews operating results in two reportable segments: (i) pipelines and transportation and (ii) wholesale marketing and terminalling. The pipelines and transportation segment provides crude oil gathering, transportation and storage services to Delek's refining operations and independent third parties. The wholesale marketing and terminalling segment provides marketing and terminalling services to Delek's refining operations and independent third parties. Decisions concerning the allocation of resources and assessment of operating performance are made based on this segmentation. Management measures the operating performance of each of its reportable segments based on the segment contribution margin. Segment contribution margin is defined as net sales less cost of sales and operating expenses, excluding depreciation and amortization. Segment reporting is more fully discussed in Note 13.

Cash and Cash Equivalents

We maintain cash and cash equivalents in accounts with large, national financial institutions. All highly liquid investments purchased with an original maturity of three months or less are considered to be cash equivalents. As of December 31, 2013 and 2012, any cash equivalents consisted primarily of overnight investments in U.S. Government obligations, bank repurchase obligations collateralized by U.S. Government obligations and bank money market accounts.

Accounts Receivable

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 has been established as of December 31, 2013 and 2012.

Two customers accounted for approximately 27.2% and 18.9% of the consolidated accounts receivable balance as of December 31, 2013 and 2012, respectively.

Inventory

Inventory consists of refined products, which are stated at the lower of cost or market on a FIFO basis.

Two vendors in the wholesale marketing and terminalling segment accounted for a total of 96.1%, 76.1% and 96.8% of our consolidated inventory purchases during the years ended December 31, 2013, 2012 and 2011, respectively.

Property, Plant and Equipment

Assets acquired in conjunction with acquisitions are recorded at estimated fair market value in accordance with the purchase method of accounting as prescribed in Financial Accounting Standards Board ("FASB") Statement of Financial Accounting Standards Codification ("ASC") 805, Business Combinations ("ASC 805"). Other acquisitions of property and equipment are carried at cost.

Betterments, renewals and extraordinary repairs that extend the life of an asset are capitalized. Maintenance and repairs are charged to expense as incurred.

Depreciation is computed using the straight-line method over management’s estimated useful lives of the related assets, except for automotive equipment, which is depreciated using a declining-balance method. The estimated useful lives are as follows:



	Years
Building and pipeline improvements	15-40
Pipelines and terminals	15-40
Asset retirement obligation assets	15-50
Other equipment	3-15

Intangible Assets

Intangible assets consist of long-term supply contracts and indefinite-lived rights of way. We amortize the definite-lived long-term supply contracts on a straight-line basis over the estimated useful life of 11.5 years. The amortization expense is included in depreciation and amortization in the accompanying consolidated statements.

Property, Plant and Equipment and Intangibles Impairment

Property, plant and equipment and definite life 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 unrecoverable by estimating the sum of the future cash flows expected to result from 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 and Potential Impairment

Goodwill in an acquisition represents the excess of the aggregate purchase price over the fair value of the identifiable net assets. Our goodwill is recorded at original fair value and is not amortized. Goodwill is subject to annual assessment to determine if an impairment of value has occurred and we perform this review annually in the fourth quarter. We could also be required to evaluate our goodwill if, prior to our annual assessment, we experience disruptions in our business, have unexpected significant declines in operating results, or sustain a permanent market capitalization decline. If an asset’s carrying amount exceeds its fair value, the impairment assessment leads to the testing of the implied fair value of the asset’s goodwill to its carrying amount. If the implied fair value is less than the carrying amount, a goodwill impairment charge is recorded. Our annual assessment of goodwill did not result in an impairment charge during the years ended December 31, 2013, 2012, or 2011.

Derivatives

We record all derivative financial instruments, including forward fuel contracts, at estimated fair value in accordance with the provisions of ASC 815, Derivatives and Hedging ("ASC 815"). Changes in the fair value of the derivative instruments are recognized in operations, unless we elect to apply the hedging treatment permitted under the provisions of ASC 815 allowing such changes to be classified as other comprehensive income. We validate the fair value of all derivative financial instruments on a monthly basis, utilizing valuations from third party financial and brokerage institutions. During the years ended December 31, 2013, 2012, and 2011, we did not elect to apply hedging treatment to our derivative positions and, therefore, all changes in fair value are reflected in the statements of operations.

Our policy under the guidance of ASC 815-10-45, Derivatives and Hedging—Other Presentation Matters ("ASC 815-10-45"), is to net the fair value amounts recognized for multiple derivative instruments executed with the same counterparty and offset these values against the cash collateral arising from these derivative positions.

Fair Value of Financial Instruments

The fair values of financial instruments are estimated based upon current market conditions and quoted market prices for the same or similar instruments. Management estimates that the carrying value approximates fair value for all of our assets and liabilities that fall under the scope of ASC 825, Financial Instruments ("ASC 825").

We apply the provisions of ASC 820, Fair Value Measurements and Disclosure ("ASC 820"), in our presentation and disclosures regarding fair value, which pertain to certain financial assets and liabilities measured at fair value in the statement of position on a recurring basis. ASC 820 defines fair value, establishes a framework for measuring fair value and expands disclosures about such measurements that are permitted or required under other accounting pronouncements. See Note 14 for further discussion.

We apply the provisions of ASC 825 as it pertains to the fair value option. This standard permits the election to carry financial instruments and certain other items similar to financial instruments at fair value on the balance sheet, with all changes in fair value reported in earnings. By electing the fair value option in conjunction with a derivative, an entity can achieve an accounting result similar to a fair value hedge without having to comply with complex hedge accounting rules. As of December 31, 2013 or 2012, we did not make the fair value election for any financial instruments not already carried at fair value in accordance with other standards.

Self-Insurance Reserves

We have no employees. Rather, we are managed by the directors and officers of our general partner. However, Delek employees providing services to the Partnership are covered under Delek’s insurance programs. Delek is primarily self-insured for workers' compensation and general liability costs, with varying limits of per claim and aggregate stop loss insurance coverage that management considers adequate. Delek has umbrella liability insurance in an amount determined reasonable by Delek's management.

Environmental Expenditures

We have historically accrued 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 our properties. This estimate is based on internal and third-party assessments of the extent of the contamination, the selected remediation technology and review of applicable environmental regulations, typically considering estimated activities and costs for the next 15 years, unless a specific longer range estimate is practicable. 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 does 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 and 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.

Asset Retirement Obligations

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.

The reconciliation of the beginning and ending carrying amounts of asset retirement obligations as of December 31, 2013 and 2012 is as follows (in thousands):



	December 31,
	2013			2012
Beginning balance	$	3,177		$	2,990
Liabilities settled	(400		)	—
Accretion expense	216			187
Ending balance	$	2,993		$	3,177

In order to determine fair value, management must make certain estimates and assumptions including, among other things, projected cash flows, a credit-adjusted risk-free rate and an assessment of market conditions that could significantly impact the estimated fair value of the asset retirement obligation.

Other Non-current Liabilities

We recognized in 2011 an estimated $6.0 million liability associated with a customer contract in our December 2011 acquisition of Paline. We amortized approximately $2.6 million to revenue during 2013. No amounts were remaining in other non-current liabilities as of December 31, 2013. The amount to amortize in 2014 is included in other current liabilities. We assumed in 2011 an estimated $2.9 million of non-current tank and pipeline inspection liabilities in the Lion Oil Acquisition, of which $0.8 million was outstanding as of December 31, 2013. During the fourth quarter of 2012, we recognized a liability of $4.5 million related to Delek's reimbursement of maintenance capital associated with three existing capital projects per the Omnibus Agreement (as defined below in Note 18—Related Party Transactions). This liability will be amortized to revenue over the estimated lives of the assets once placed in service. The outstanding liability as of December 31, 2013 was $4.3 million.

Revenue Recognition

Revenues for products sold are recorded at the point of sale upon delivery of product, which is the point at which title to the product is transferred, and when payment has either been received or collection is reasonably assured. Service revenues are recognized as crude oil and refined products are shipped through, delivered by or stored in our pipelines, terminals and storage facility assets, as applicable. We do not recognize product sales revenues for these services, as title on the product never passes to us. All revenues are based on regulated tariff rates or contractual rates.

Cost of Goods Sold and Operating Expenses

Cost of goods sold includes all costs of refined products, additives and related transportation. We do not recognize product cost of sales related to our shipping, delivering and storage services, as title to the product never passes to us. Operating expenses include the costs associated with the operation of owned terminals, terminalling expense at third-party locations and pipeline maintenance costs.

Sales, Use and Excise Taxes

Our policy is to exclude sales, use and excise taxes from revenue when we are an agent of the taxing authority, in accordance with ASC 605-45, Revenue Recognition—Principal Agent Considerations.

Deferred Financing Costs

Deferred financing costs are included in other non-current assets in the accompanying balance sheets and represent expenses related to issuing and amending our revolving credit facility. These amounts are amortized ratably over the remaining term of our revolving credit facility and are included in interest expense in the accompanying consolidated financial statements.

Operating Leases

We lease certain equipment and have surface leases under various operating lease arrangements, most of which provide the option, after the initial lease term, to renew the leases. None of these lease arrangements include fixed rental rate increases.

Lease expense for all operating leases, including the Tyler Predecessor, totaled $0.5 million, $0.5 million, and $0.3 million for the years ended December 31, 2013, 2012, and 2011, respectively.

Income Taxes

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 his, her or its share of items of income, gain, loss and deduction in computing his, her or 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, the acquisition price of such partner's units and the taxable income allocation requirements under our partnership agreement.

We are subject to income taxes in certain states that do not follow the federal tax treatment of Partnerships. These income taxes are accounted for under the provisions of ASC 740, Income Taxes (ASC 740). This statement generally requires DKL 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; however, there are currently no audits for any tax periods in progress.

Prior to the Offering, the Predecessor was a corporation included in its parent's consolidated tax return. As such, the Predecessor was subject to both federal and state income taxes and recorded 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.

The Partnership had total tax expense of $0.8 million in 2013. Subsequent to the Offering, the Partnership had total tax expense of $0.1 million in 2012. The majority of the change in deferred tax assets and liabilities relates to the Predecessor's conversion to a partnership and no longer being subject to federal income tax. The conversion from a taxable corporation to a passthrough resulted in a one-time tax benefit of $18.5 million in 2012.

Equity Based Compensation

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 includes unit options, restricted units, phantom units, unit appreciation rights, distribution equivalent rights, other unit-based awards and unit awards. Phantom units are measured based on the fair market value of the underlying stock on the date of grant. The fair value of our phantom units is determined based on the closing 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 a five-year service period. The phantom unit awards are settled in units.

Comprehensive Income

Comprehensive income for the years ended December 31, 2013, 2012, and 2011 was equivalent to net income.

New Accounting Pronouncements

In July 2012, the FASB issued guidance regarding testing indefinite-lived intangible assets for impairment that gives companies the option to perform a qualitative assessment before calculating the fair value of the indefinite-lived intangible asset. Under the guidance, if this option is selected, a company is not required to calculate the fair value of the indefinite-lived intangible unless the entity determines it is more likely than not that its fair value is less than its carrying amount. In October 2012, the FASB issued guidance regarding the application of the qualitative assessment permitted under the Accounting Standards Update 2012-02, issued in July. The guidance requires companies to focus on the significant inputs used to determine the fair value of indefinite-lived intangible assets when companies opt to perform the qualitative assessment. Companies must then evaluate the impact of certain events and circumstances that could have affected those inputs and weigh the identified factors prior to concluding whether the asset is impaired. As significant judgment is applied to conclude that an indefinite-lived intangible asset is not impaired based on a qualitative assessment, the analyses performed by the Company should be supported by clear documentation of the factors considered, including any necessary quantitative calculations. The guidance is effective for interim and annual reporting periods beginning January 1, 2013, but early adoption is permitted. The adoption of this guidance did not affect our business, financial position or results of operations.

In December 2011, the FASB issued guidance requiring the disclosure of information about offsetting and related arrangements to enable users of financial statements to understand the effect of these arrangements on financial position. The guidance requires the disclosure of both gross information and net information about both instruments and transactions eligible for offset in the balance sheet and instruments and transactions subject to an agreement similar to a master netting arrangement. In January 2013, the FASB issued an update limiting the scope of the offsetting disclosure requirements established by the original guidance, to certain derivatives (including bifurcated embedded derivatives), repurchase agreements and reverse repurchase agreements, and securities lending and securities borrowing transactions that are eligible for offset on the balance sheet or are subject to an agreement similar to a master netting arrangement, irrespective of whether they are offset on the balance sheet. This update amends the guidance that required companies to apply the requirements to all recognized financial instruments. The original and updated guidance is effective for interim and annual reporting periods beginning January 1, 2013 and retrospectively for all periods presented on the balance sheet. The adoption of this guidance did not affect our business, financial position or results of operations, but resulted in additional disclosures (see Note 14).
