Significant Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation These consolidated financial statements were prepared in accordance with U.S. GAAP. These financial statements include the consolidated accounts of CrossAmerica and subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results and outcomes could differ from those estimates and assumptions. On an ongoing basis, management reviews its estimates based on currently available information. Changes in facts and circumstances could result in revised estimates and assumptions.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all short-term investments with maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents are stated at cost, which, for cash equivalents, approximates fair value due to their short-term maturity. We are potentially subject to financial instrument concentration of credit risk through our cash and cash equivalents. We maintain cash and cash equivalents with several major financial institutions. We have not experienced any losses on our cash equivalents.
Receivables	Receivables and Financial Instrument Credit Losses In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.” This standard requires that for most financial assets, losses be based on an expected loss approach which includes estimates of losses over the life of exposure that considers historical, current and forecasted information. Expanded disclosures related to the methods used to estimate the losses as well as a specific disaggregation of balances for financial assets are also required. The impact of adopting this guidance effective January 1, 2020 was not material. The primary financial instrument within the scope of this guidance is our accounts receivable, which mainly result from the sale of motor fuels to customers. Our accounts receivable is generally considered as having a similar risk profile. Credit is extended to a customer, generally a dealer or a commission agent, based on an evaluation of the customer’s financial condition prior to entering into fuel supply and/or lease agreements. In certain circumstances, collateral may be required from the customer and fuel and lease agreements are generally cross-collateralized when applicable. Receivables are recorded at face value, without interest or discount. The allowance for credit losses is generally based upon historical experience while also factoring in any new business conditions that might impact the historical analysis, such as market conditions and bankruptcies of particular customers. Credit loss expense is included in general and administrative expenses. We review all accounts receivable balances on at least a quarterly basis.
Inventories	Inventories Motor fuel inventory consists of gasoline, diesel fuel and other petroleum products and is stated at the lower of average cost or net realizable value using the first-in, first-out method. We record inventory from the time of the purchase of motor fuels from third-party suppliers until the retail sale to the end customer. Retail site merchandise inventory is valued at the lower of average cost or net realizable value using the first-in, first-out method, written down, as necessary, for potentially obsolete or slow-moving inventory.
Asset Acquisitions and Business Combinations	Asset Acquisitions and Business Combinations When closing on an acquisition, we must first determine whether substantially all of the fair value of the set of gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set is not a business. If this threshold is not met, we determine whether the set meets the definition of a business. A business is defined as an integrated set of assets and activities that is capable of being conducted and managed for the purpose of providing a return to investors or other owners, members or participants. A business typically has inputs, processes applied to those inputs and outputs that are used to generate a return to investors, but outputs are not required for a set to be a business. A business must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. We account for asset acquisitions (i.e. transactions involving the acquisition of a set of assets that does not meet the definition of a business) in accordance with the guidance under ASC 805-50 and other applicable guidance. Asset acquisitions are generally accounted for by allocating the cost of the acquisition, including acquisition costs, to the individual assets acquired and liabilities assumed on a relative fair value basis. We account for business combinations in accordance with the guidance under ASC 805–Business Combinations. The purchase price is recorded for assets acquired and liabilities assumed based on fair value. The excess of the fair value of the consideration conveyed over the fair value of the net assets acquired is recorded as goodwill. The income statement includes the results of operations for each acquisition from their respective date of acquisition. Whether we account for a transaction as an asset acquisition or a business combination, determining the fair value of assets and liabilities requires management’s judgment, the utilization of independent valuation experts and involves the use of significant estimates and assumptions with respect to the timing and amounts of future cash inflows and outflows, discount rates, market prices and asset lives, among other items. The judgments made in the determination of the estimated fair value assigned to the assets acquired, the liabilities assumed and any noncontrolling interest in the investee, as well as the estimated useful life of each asset and the duration of each liability, can materially impact the financial statements in periods after acquisition, such as through depreciation and amortization.
Property and Equipment	Property and Equipment Property and equipment is recorded at cost, which equals fair value in the case of a business combination or generally approximates fair value in the case of an asset acquisition. Depreciation is recognized using the straight-line method over the estimated useful lives of the related assets, including: 10 to 20 years for buildings and improvements and three to 30 years for equipment. Amortization of leasehold improvements is based upon the shorter of the remaining terms of the leases including renewal periods that are reasonably assured, or the estimated useful lives, which generally range from seven to 10 years. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Maintenance and repairs are charged to operations as incurred. Gains or losses on the disposition of property and equipment are recorded in the period the sale meets the criteria for recognition.
Intangible Assets	Intangible Assets Intangible assets are recorded at fair value in the case of a business combination or at a value that generally approximates fair value in the case of an asset acquisition. Intangible assets associated with wholesale fuel supply contracts and wholesale fuel distribution rights are amortized over 10 years. Trademarks and licenses are amortized over periods from five to 15 years. Covenants not to compete are amortized over the shorter of the contract term or five years. Intangible assets associated with above and below market leases in which we are the lessor are amortized over the applicable lease term. Intangible assets with finite useful lives are amortized over their respective estimated useful lives and reviewed for impairment if we believe that changes or triggering events have occurred that could have caused the carrying value of the intangible assets to exceed its fair value. Intangible assets with indefinite lives are not amortized but are tested for impairment annually or more frequently if events and circumstances indicate that the intangible assets might be impaired.
Impairment of Assets	Impairment of Assets Long-lived assets, which include property and equipment and finite-lived intangible assets, are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. A long-lived asset is not recoverable if its carrying amount exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. If a long-lived asset is not recoverable, an impairment loss is recognized for the amount by which the carrying amount of the long-lived asset exceeds its fair value, with fair value determined based on discounted estimated net cash flows or other appropriate methods.
Goodwill	Goodwill Goodwill represents the excess of cost over the fair value of net assets of businesses acquired. Goodwill is not amortized, but instead is tested for impairment at the reporting unit level at least annually, and more frequently if events and circumstances indicate that the goodwill might be impaired. The annual impairment testing date of goodwill is October 1. In performing our annual impairment analysis, ASC 350–20, Intangibles–Goodwill and Other, allows us to use qualitative factors to determine whether it is more likely than not (likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount, including goodwill. If, after assessing the totality of events or circumstances, we determine that it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, no further testing is necessary. However, if we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we perform the goodwill impairment test. In the goodwill impairment test, the reporting unit’s carrying amount (including goodwill) and its fair value are compared. If the estimated fair value of a reporting unit is less than the carrying value, an impairment charge is recognized for the deficit up to the amount of goodwill recorded. No goodwill was impaired for any period presented.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs that are incurred in connection with the issuance of debt are deferred and amortized to interest expense using the straight-line method (which approximates the effective interest method) over the contractual term of the underlying indebtedness. Debt issuance costs are classified as a reduction of the associated liability.
Environmental Matters	Environmental Matters Liabilities for future remediation costs are recorded when environmental assessments from governmental regulatory agencies and/or remedial efforts are probable and the costs can be reasonably estimated. Other than for assessments, the timing and magnitude of these accruals generally are based on the completion of investigations or other studies or a commitment to a formal plan of action. Environmental liabilities are based on best estimates of probable undiscounted future costs using currently available technology and applying current regulations, as well as our own internal environmental policies. Environmental liabilities are difficult to assess and estimate due to uncertainties related to the magnitude of possible remediation, the timing of such remediation and the determination of our obligation in proportion to other parties. Such estimates are subject to change due to many factors, including the identification of new retail sites requiring remediation, changes in environmental laws and regulations and their interpretation, additional information related to the extent and nature of remediation efforts and potential improvements in remediation technologies. Amounts recorded for environmental liabilities have not been reduced by possible recoveries from third parties.
Asset Retirement Obligations	Asset Retirement Obligations We record a liability, which is referred to as an asset retirement obligation, at fair value for the estimated cost to remove underground storage tanks (USTs) used to store motor fuel at owned and leased retail sites at the time we incur that liability, which is generally when the UST is installed or upon entering the lease. We record a discounted liability for the fair value of an asset retirement obligation with a corresponding increase to the carrying value of the related long-lived asset. We depreciate the amount added to property and equipment and recognize accretion expense in connection with the discounted liability over the estimated remaining life of the UST. Accretion expense is reflected in depreciation, amortization and accretion expense. We base our estimates of the anticipated future costs for removal of a UST on our prior experience with removal. Removal costs include the cost to remove the USTs, soil remediation costs resulting from the spillage of small quantities of motor fuel in the normal operations of our business and other miscellaneous costs. We review our assumptions for computing the estimated liability for the removal of USTs on an annual basis. Any change in estimated cash flows is reflected as an adjustment to the liability and the associated asset.
Segment Reporting	Segment Reporting We present our segment reporting in accordance with ASC 280–Segment Reporting and engage in both the wholesale and retail distribution of motor fuels, primarily gasoline and diesel fuel. We present our results to our chief operating decision maker segregated between wholesale and retail activities. As a result, we are deemed to conduct our business in two segments: 1) the wholesale segment and 2) the retail segment. The class of customer and gross margins are sufficiently different between these two businesses to warrant two reportable segments. See Note 24 for additional information.
Revenue Recognition	Revenue Recognition We have applied ASC 606 since January 1, 2018. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. This guidance applies to over 90% of our revenues as the only primary revenue stream outside the scope of this guidance is rental income. Revenues from the delivery of motor fuel are recorded at the time of delivery to our customers, by which time the price is fixed, title to the products has transferred and payment has either been received or collection is reasonably assured, net of applicable discounts and allowances. Incremental costs incurred to obtain certain contracts with customers are deferred and amortized over the contract term and are included in other noncurrent assets on the balance sheets. Amortization of such costs are classified as a reduction of operating revenues. Revenues from the sale of convenience store products are recognized at the time of sale to the customer. Revenues from leasing arrangements for which we are the lessor are recognized ratably over the term of the underlying lease. In transactions in which we sell and lease back property, we apply guidance from ASC 606 in determining whether the transfer of the property should be accounted for as a sale. Specifically, we assess if we have satisfied a performance obligation by transferring control of the property. In 2020, we closed on tranches of the Asset Exchange Agreement and CST Fuel Supply Exchange with Circle K, both representing largely nonmonetary transactions. We apply provisions of ASC 606, ASC 845 and ASC 860 as applicable to our nonmonetary exchanges based on the individual facts and circumstances of each transaction. For these particular transactions, we estimated the fair value of the assets divested and acquired based on an income approach using discount rates commensurate with the risk inherent in the cash flows, similar to how we estimate fair value in an asset acquisition or business combination as further described below. We record gains and losses as required by the applicable guidance, in these cases representing the excess of the fair value of the assets and cash consideration received less the carrying value of the assets divested. See Notes 3 and 4 to the financial statements for additional information. See Notes 7 and 24 for additional information on our revenues and related receivables.
Cost of Sales	Cost of Sales We include in our cost of sales all costs we incur to acquire motor fuel and merchandise, including the costs of purchasing, storing and transporting inventory prior to delivery to our customers. A component of our cost of sales is the discount for prompt payment and other rebates, discounts and incentives offered by our suppliers. Prompt payment discounts from suppliers are based on a percentage of the purchase price of motor fuel and the dollar value of these discounts varies with motor fuel prices. Cost of sales does not include any depreciation of our property and equipment, as these amounts are included in depreciation, amortization and accretion expense on our statements of income.
Motor Fuel Taxes	Motor Fuel Taxes LGW collects motor fuel taxes, which consist of various pass-through taxes collected from customers on behalf of taxing authorities and remits such taxes directly to those taxing authorities. LGW’s accounting policy is to exclude the taxes collected and remitted from wholesale revenues and cost of sales and account for them as liabilities. LGWS’s retail sales and cost of sales include motor fuel taxes as the taxes are included in the cost paid for motor fuel and LGWS has no direct responsibility to collect or remit such taxes to the taxing authorities.
Lease Accounting	Lease Accounting We lease certain retail sites from third parties under long-term arrangements with various expiration dates. Through December 31, 2018, we accounted for leases in accordance with ASC 840–Leases. ASC 842–Leases requires the recognition of lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This guidance was effective for us on January 1, 2019. We elected the package of practical expedients permitted under the transition guidance within the new standard, which allows us to not reassess: 1) whether any expired or existing contracts are or contain leases; 2) lease classifications for any expired or existing leases; and 3) initial direct costs for any existing leases. We also elected the practical expedient to not assess whether existing or expired land easements that were not previously accounted for as leases under ASC 840 are or contain a lease under ASC 842. We did not elect the hindsight practical expedient and thus did not reassess the lease term for existing leases. We did not elect the practical expedient to not separate lease components from non-lease components for any classes of assets. We made an accounting policy election to not recognize lease assets and lease liabilities on the balance sheet for leases with an initial term of one year or less. We elected the current period adjustment transition method as permitted by ASU 2018-10 and recorded a cumulative effect adjustment to equity effective January 1, 2019. We are the lessee in certain sale-leaseback transactions for certain retail sites, and as we have continuing involvement in the underlying retail sites through a sublease with a lessee dealer, the sale-leaseback arrangements were accounted for as financing transactions under ASC 840. There was no impact from the adoption of this ASU on the accounting for our capital (now called finance) lease obligations. Since our previous sale-leaseback transactions were accounted for as failed sale-leasebacks, we were required to reassess these leases under the new guidance as part of adopting ASC 842. We concluded that control, including the significant risks and rewards of ownership, transferred to the buyer-lessor at the inception of each sale-leaseback transaction, and as a result these leasing transactions do not represent financing obligations under ASC 842. Therefore, these leases are accounted for as operating leases under the new guidance. In order to measure our lease liability under our leases as lessee, we are required to discount our minimum rental payments using the rate implicit in the lease, unless such rate cannot be readily determined, in which case our incremental borrowing rate is used. As we do not know the amount of our lessors’ initial direct costs, we are generally unable to determine the rate implicit in our leases. As a result, we generally use our incremental borrowing rate, which is the rate we would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term in a similar economic environment. We considered the rates we paid in previous financing and sale-leaseback transactions, the rates on our borrowings under our prior secured revolving credit facility and mortgage rates on commercial properties for various terms in developing our incremental borrowing rates. Since we did not restate prior periods as part of adopting this guidance, our results for 2019 are not directly comparable to our results for periods before January 1, 2019. Specifically, payments on our failed sale-leaseback obligations were characterized as principal and interest expense in periods prior to January 1, 2019. Beginning on January 1, 2019, these payments are characterized as rent expense and thus reduce gross profit and operating income (primarily from the Wholesale segment) relative to the results reported for periods prior to January 1, 2019. See Notes 13, 15 and 24 for additional information. ASC 842 requires leases be evaluated and classified as either operating or finance for financial reporting purposes. The lease term used for lease evaluation includes option periods only in instances in which the exercise of the option period is reasonably certain. Generally, lease payments are expensed on a straight-line basis over the term of the lease including renewal periods that are reasonably certain at the inception of the lease. In addition to these lease payments, certain leases require additional contingent payments based on sales volume or future inflation, which are expensed as incurred.
Income Taxes	Income Taxes Our wholly owned taxable subsidiaries recognize deferred income tax assets and liabilities for the expected future income tax consequences of temporary differences between financial statement carrying amounts and the related income tax basis. Income tax attributable to our earnings and losses, excluding the earnings and losses of our wholly owned taxable subsidiaries, are assessed at the individual level of the unitholder. Accordingly, we do not record a provision for income taxes other than for those earnings and losses generated or incurred by our wholly owned taxable subsidiaries. Tax positions not meeting the more-likely-than-not recognition threshold at the financial statement date may not be recognized or continue to be recognized under the accounting guidance for income taxes. Where required, we recognize interest and penalties for uncertain tax positions in income taxes. Valuation allowances are initially recorded and reevaluated each reporting period by assessing the likelihood of the ultimate realization of a deferred tax asset. Management considers a number of factors in assessing the realization of a deferred tax asset, including the reversal of temporary differences, projections of future taxable income and ongoing prudent and feasible tax planning strategies. The amount of deferred tax assets ultimately realized may differ materially from the estimates utilized in the computation of valuation allowances and may materially impact the financial statements in the future.
Earnings Per Common Unit	Earnings per Common Unit In addition to the common units, we have identified the IDRs as participating securities and compute income per unit using the two-class method under which any excess of distributions declared over net income shall be allocated to the partners based on their respective sharing of income specified in the Partnership Agreement. Net income per common unit applicable to limited partners is computed by dividing the limited partners’ interest in net income, after deducting any incentive distributions, by the weighted-average number of outstanding common units. See Note 23 for disclosure regarding the elimination of the IDRs, which closed on February 6, 2020.
Interest Rate Swap Contracts	Interest Rate Swap Contracts Commencing in March 2020, the Partnership started to use interest rate swap contracts to reduce its exposure to unfavorable changes in interest rates. The Partnership accounts for derivative contracts in accordance with ASC Topic 815, “Derivatives and Hedging,” and recognizes derivative instruments as either assets or liabilities on the balance sheet and measures those instruments at fair value. The changes in fair value of the derivative transactions are presented in accumulated other comprehensive income and reclassified to interest expense as the interest payments on our credit facility are made. The portion of derivative positions that are anticipated to settle within a year are included in other current assets and accrued expenses and other current liabilities, while the portion of derivative positions that are anticipated to settle beyond a year are recorded in other assets or other long-term liabilities. Cash inflows and outflows related to derivative instruments are included as a component of operating activities on the statements of cash flows, consistent with the classification of the hedged interest payments on our credit facility. See Note 14 for information related to our interest rate swap contracts.
New Accounting Guidance Pending Adopted	New Accounting Guidance Pending Adoption Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes.” The amendments in this Update simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC 740. The amendments also improve consistent application of and simplify GAAP for other areas of ASC 740 by clarifying and amending existing guidance, such as the accounting for a franchise tax (or similar tax) that is partially based on income. This standard was effective January 1, 2021 for the Partnership. The impact of adopting this guidance was not material.
Concentration Risks	Concentration Risks For 2019 and 2018, we distributed approximately 8% and 11% of our total wholesale distribution volume to Dunne Manning Stores LLC (DMS), an entity associated with the family of a member of the Board and DMS accounted for approximately 7% and 15% of our rental income, respectively. See Note 5 for information regarding the termination of leases with DMS in connection with the acquisition of retail and wholesale assets. For 2019 and 2018, we distributed 6% and 7% of our total wholesale distribution volume to Circle K retail sites and received 14% and 20% of our rental income from Circle K, respectively. For more information regarding transactions with DMS and its affiliates and Circle K, see Note 16. Approximately 12% of our rent income for 2020 was from one multi-site operator. In 2020, our wholesale business purchased approximately 29%, 22%, 13% and 10% of its motor fuel from ExxonMobil, BP, Motiva and Marathon, respectively. In 2019, our wholesale business purchased approximately 26%, 22%, 15% and 12% of its motor fuel from ExxonMobil, BP, Circle K and Motiva, respectively. In 2018, our wholesale business purchased approximately 26%, 26%, 13% and 10% of its motor fuel from ExxonMobil, BP, Motiva and Circle K, respectively. No other fuel suppliers accounted for 10% or more of our motor fuel purchases during 2020, 2019 or 2018. Approximately 16% of our motor fuel gallons sold was delivered by one carrier.
COVID-19 Pandemic	COVID-19 Pandemic During the first quarter of 2020, an outbreak of a novel strain of coronavirus spread worldwide, including to the U.S., posing public health risks that have reached pandemic proportions. We experienced a sharp decrease in fuel volume in mid-to-late March. Although fuel volumes recovered during the second half of 2020, they remain below historical levels. For 2020, the negative impact of the volume decrease on fuel gross profit was partially offset by the positive impact from the decline in crude prices, which increased DTW margins. As a result of the implications of COVID-19, we assessed property and equipment, other long-lived assets and goodwill for impairment and concluded no assets were impaired as of March 31, 2020. No indicators of impairment stemming from the COVID-19 Pandemic have been identified since. See Note 9 for information regarding impairment charges related primarily to classifying sites as assets held for sale. We cannot predict the scope and severity with which COVID-19 will impact our business, financial condition, results of operations and cash flows. Sustained decreases in fuel volume or erosion of margin could have a material adverse effect on our results of operations, cash flow, financial position and ultimately our ability to pay distributions.

Significant Accounting Policies [Abstract]

These consolidated financial statements were prepared in accordance with U.S. GAAP. These financial statements include the consolidated accounts of CrossAmerica and subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results and outcomes could differ from those estimates and assumptions. On an ongoing basis, management reviews its estimates based on currently available information. Changes in facts and circumstances could result in revised estimates and assumptions.

Cash and Cash Equivalents

We consider all short-term investments with maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents are stated at cost, which, for cash equivalents, approximates fair value due to their short-term maturity. We are potentially subject to financial instrument concentration of credit risk through our cash and cash equivalents. We maintain cash and cash equivalents with several major financial institutions. We have not experienced any losses on our cash equivalents.

Receivables

Receivables and Financial Instrument Credit Losses

In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.” This standard requires that for most financial assets, losses be based on an expected loss approach which includes estimates of losses over the life of exposure that considers historical, current and forecasted information. Expanded disclosures related to the methods used to estimate the losses as well as a specific disaggregation of balances for financial assets are also required. The impact of adopting this guidance effective January 1, 2020 was not material.

Our accounts receivable is generally considered as having a similar risk profile. Credit is extended to a customer, generally a dealer or a commission agent, based on an evaluation of the customer’s financial condition prior to entering into fuel supply and/or lease agreements. In certain circumstances, collateral may be required from the customer and fuel and lease agreements are generally cross-collateralized when applicable. Receivables are recorded at face value, without interest or discount.

The allowance for credit losses is generally based upon historical experience while also factoring in any new business conditions that might impact the historical analysis, such as market conditions and bankruptcies of particular customers. Credit loss expense is included in general and administrative expenses. We review all accounts receivable balances on at least a quarterly basis.

Inventories

Motor fuel inventory consists of gasoline, diesel fuel and other petroleum products and is stated at the lower of average cost or net realizable value using the first-in, first-out method. We record inventory from the time of the purchase of motor fuels from third-party suppliers until the retail sale to the end customer.

Retail site merchandise inventory is valued at the lower of average cost or net realizable value using the first-in, first-out method, written down, as necessary, for potentially obsolete or slow-moving inventory.

Asset Acquisitions and Business Combinations

When closing on an acquisition, we must first determine whether substantially all of the fair value of the set of gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set is not a business. If this threshold is not met, we determine whether the set meets the definition of a business.

A business is defined as an integrated set of assets and activities that is capable of being conducted and managed for the purpose of providing a return to investors or other owners, members or participants. A business typically has inputs, processes applied to those inputs and outputs that are used to generate a return to investors, but outputs are not required for a set to be a business. A business must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs.

We account for asset acquisitions (i.e. transactions involving the acquisition of a set of assets that does not meet the definition of a business) in accordance with the guidance under ASC 805-50 and other applicable guidance. Asset acquisitions are generally accounted for by allocating the cost of the acquisition, including acquisition costs, to the individual assets acquired and liabilities assumed on a relative fair value basis.

We account for business combinations in accordance with the guidance under ASC 805–Business Combinations. The purchase price is recorded for assets acquired and liabilities assumed based on fair value. The excess of the fair value of the consideration conveyed over the fair value of the net assets acquired is recorded as goodwill.

The income statement includes the results of operations for each acquisition from their respective date of acquisition.

Whether we account for a transaction as an asset acquisition or a business combination, determining the fair value of assets and liabilities requires management’s judgment, the utilization of independent valuation experts and involves the use of significant estimates and assumptions with respect to the timing and amounts of future cash inflows and outflows, discount rates, market prices and asset lives, among other items. The judgments made in the determination of the estimated fair value assigned to the assets acquired, the liabilities assumed and any noncontrolling interest in the investee, as well as the estimated useful life of each asset and the duration of each liability, can materially impact the financial statements in periods after acquisition, such as through depreciation and amortization.

Property and Equipment

Property and equipment is recorded at cost, which equals fair value in the case of a business combination or generally approximates fair value in the case of an asset acquisition. Depreciation is recognized using the straight-line method over the estimated useful lives of the related assets, including: 10 to 20 years for buildings and improvements and three to 30 years for equipment. Amortization of leasehold improvements is based upon the shorter of the remaining terms of the leases including renewal periods that are reasonably assured, or the estimated useful lives, which generally range from seven to 10 years.

Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized. Maintenance and repairs are charged to operations as incurred. Gains or losses on the disposition of property and equipment are recorded in the period the sale meets the criteria for recognition.

Intangible Assets

Intangible assets are recorded at fair value in the case of a business combination or at a value that generally approximates fair value in the case of an asset acquisition. Intangible assets associated with wholesale fuel supply contracts and wholesale fuel distribution rights are amortized over 10 years. Trademarks and licenses are amortized over periods from five to 15 years. Covenants not to compete are amortized over the shorter of the contract term or five years. Intangible assets associated with above and below market leases in which we are the lessor are amortized over the applicable lease term. Intangible assets with finite useful lives are amortized over their respective estimated useful lives and reviewed for impairment if we believe that changes or triggering events have occurred that could have caused the carrying value of the intangible assets to exceed its fair value. Intangible assets with indefinite lives are not amortized but are tested for impairment annually or more frequently if events and circumstances indicate that the intangible assets might be impaired.

Impairment of Assets

Long-lived assets, which include property and equipment and finite-lived intangible assets, are tested for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. A long-lived asset is not recoverable if its carrying amount exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. If a long-lived asset is not recoverable, an impairment loss is recognized for the amount by which the carrying amount of the long-lived asset exceeds its fair value, with fair value determined based on discounted estimated net cash flows or other appropriate methods.

Goodwill

Goodwill represents the excess of cost over the fair value of net assets of businesses acquired. Goodwill is not amortized, but instead is tested for impairment at the reporting unit level at least annually, and more frequently if events and circumstances indicate that the goodwill might be impaired. The annual impairment testing date of goodwill is October 1.

In performing our annual impairment analysis, ASC 350–20, Intangibles–Goodwill and Other, allows us to use qualitative factors to determine whether it is more likely than not (likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount, including goodwill.

If, after assessing the totality of events or circumstances, we determine that it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, no further testing is necessary. However, if we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we perform the goodwill impairment test.

In the goodwill impairment test, the reporting unit’s carrying amount (including goodwill) and its fair value are compared. If the estimated fair value of a reporting unit is less than the carrying value, an impairment charge is recognized for the deficit up to the amount of goodwill recorded.

No goodwill was impaired for any period presented.

Debt Issuance Costs

Debt issuance costs that are incurred in connection with the issuance of debt are deferred and amortized to interest expense using the straight-line method (which approximates the effective interest method) over the contractual term of the underlying indebtedness. Debt issuance costs are classified as a reduction of the associated liability.

Environmental Matters

Liabilities for future remediation costs are recorded when environmental assessments from governmental regulatory agencies and/or remedial efforts are probable and the costs can be reasonably estimated. Other than for assessments, the timing and magnitude of these accruals generally are based on the completion of investigations or other studies or a commitment to a formal plan of action. Environmental liabilities are based on best estimates of probable undiscounted future costs using currently available technology and applying current regulations, as well as our own internal environmental policies. Environmental liabilities are difficult to assess and estimate due to uncertainties related to the magnitude of possible remediation, the timing of such remediation and the determination of our obligation in proportion to other parties. Such estimates are subject to change due to many factors, including the identification of new retail sites requiring remediation, changes in environmental laws and regulations and their interpretation, additional information related to the extent and nature of remediation efforts and potential improvements in remediation technologies. Amounts recorded for environmental liabilities have not been reduced by possible recoveries from third parties.

Asset Retirement Obligations

We record a liability, which is referred to as an asset retirement obligation, at fair value for the estimated cost to remove underground storage tanks (USTs) used to store motor fuel at owned and leased retail sites at the time we incur that liability, which is generally when the UST is installed or upon entering the lease. We record a discounted liability for the fair value of an asset retirement obligation with a corresponding increase to the carrying value of the related long-lived asset. We depreciate the amount added to property and equipment and recognize accretion expense in connection with the discounted liability over the estimated remaining life of the UST. Accretion expense is reflected in depreciation, amortization and accretion expense. We base our estimates of the anticipated future costs for removal of a UST on our prior experience with removal. Removal costs include the cost to remove the USTs, soil remediation costs resulting from the spillage of small quantities of motor fuel in the normal operations of our business and other miscellaneous costs. We review our assumptions for computing the estimated liability for the removal of USTs on an annual basis. Any change in estimated cash flows is reflected as an adjustment to the liability and the associated asset.

Segment Reporting

We present our segment reporting in accordance with ASC 280–Segment Reporting and engage in both the wholesale and retail distribution of motor fuels, primarily gasoline and diesel fuel. We present our results to our chief operating decision maker segregated between wholesale and retail activities. As a result, we are deemed to conduct our business in two segments: 1) the wholesale segment and 2) the retail segment. The class of customer and gross margins are sufficiently different between these two businesses to warrant two reportable segments. See Note 24 for additional information.

Revenue Recognition

We have applied ASC 606 since January 1, 2018. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. This guidance applies to over 90% of our revenues as the only primary revenue stream outside the scope of this guidance is rental income.

Revenues from the delivery of motor fuel are recorded at the time of delivery to our customers, by which time the price is fixed, title to the products has transferred and payment has either been received or collection is reasonably assured, net of applicable discounts and allowances. Incremental costs incurred to obtain certain contracts with customers are deferred and amortized over the contract term and are included in other noncurrent assets on the balance sheets. Amortization of such costs are classified as a reduction of operating revenues.

Revenues from the sale of convenience store products are recognized at the time of sale to the customer.

Revenues from leasing arrangements for which we are the lessor are recognized ratably over the term of the underlying lease.

In transactions in which we sell and lease back property, we apply guidance from ASC 606 in determining whether the transfer of the property should be accounted for as a sale. Specifically, we assess if we have satisfied a performance obligation by transferring control of the property.

In 2020, we closed on tranches of the Asset Exchange Agreement and CST Fuel Supply Exchange with Circle K, both representing largely nonmonetary transactions. We apply provisions of ASC 606, ASC 845 and ASC 860 as applicable to our nonmonetary exchanges based on the individual facts and circumstances of each transaction. For these particular transactions, we estimated the fair value of the assets divested and acquired based on an income approach using discount rates commensurate with the risk inherent in the cash flows, similar to how we estimate fair value in an asset acquisition or business combination as further described below. We record gains and losses as required by the applicable guidance, in these cases representing the excess of the fair value of the assets and cash consideration received less the carrying value of the assets divested. See Notes 3 and 4 to the financial statements for additional information.

See Notes 7 and 24 for additional information on our revenues and related receivables.

Cost of Sales

We include in our cost of sales all costs we incur to acquire motor fuel and merchandise, including the costs of purchasing, storing and transporting inventory prior to delivery to our customers. A component of our cost of sales is the discount for prompt payment and other rebates, discounts and incentives offered by our suppliers. Prompt payment discounts from suppliers are based on a percentage of the purchase price of motor fuel and the dollar value of these discounts varies with motor fuel prices. Cost of sales does not include any depreciation of our property and equipment, as these amounts are included in depreciation, amortization and accretion expense on our statements of income.

Motor Fuel Taxes

LGW collects motor fuel taxes, which consist of various pass-through taxes collected from customers on behalf of taxing authorities and remits such taxes directly to those taxing authorities. LGW’s accounting policy is to exclude the taxes collected and remitted from wholesale revenues and cost of sales and account for them as liabilities. LGWS’s retail sales and cost of sales include motor fuel taxes as the taxes are included in the cost paid for motor fuel and LGWS has no direct responsibility to collect or remit such taxes to the taxing authorities.

Lease Accounting

We lease certain retail sites from third parties under long-term arrangements with various expiration dates.

Through December 31, 2018, we accounted for leases in accordance with ASC 840–Leases.

ASC 842–Leases requires the recognition of lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This guidance was effective for us on January 1, 2019.

We elected the package of practical expedients permitted under the transition guidance within the new standard, which allows us to not reassess: 1) whether any expired or existing contracts are or contain leases; 2) lease classifications for any expired or existing leases; and 3) initial direct costs for any existing leases. We also elected the practical expedient to not assess whether existing or expired land easements that were not previously accounted for as leases under ASC 840 are or contain a lease under ASC 842. We did not elect the hindsight practical expedient and thus did not reassess the lease term for existing leases. We did not elect the practical expedient to not separate lease components from non-lease components for any classes of assets. We made an accounting policy election to not recognize lease assets and lease liabilities on the balance sheet for leases with an initial term of one year or less. We elected the current period adjustment transition method as permitted by ASU 2018-10 and recorded a cumulative effect adjustment to equity effective January 1, 2019.

We are the lessee in certain sale-leaseback transactions for certain retail sites, and as we have continuing involvement in the underlying retail sites through a sublease with a lessee dealer, the sale-leaseback arrangements were accounted for as financing transactions under ASC 840.

There was no impact from the adoption of this ASU on the accounting for our capital (now called finance) lease obligations.

Since our previous sale-leaseback transactions were accounted for as failed sale-leasebacks, we were required to reassess these leases under the new guidance as part of adopting ASC 842. We concluded that control, including the significant risks and rewards of ownership, transferred to the buyer-lessor at the inception of each sale-leaseback transaction, and as a result these leasing transactions do not represent financing obligations under ASC 842. Therefore, these leases are accounted for as operating leases under the new guidance.

In order to measure our lease liability under our leases as lessee, we are required to discount our minimum rental payments using the rate implicit in the lease, unless such rate cannot be readily determined, in which case our incremental borrowing rate is used. As we do not know the amount of our lessors’ initial direct costs, we are generally unable to determine the rate implicit in our leases. As a result, we generally use our incremental borrowing rate, which is the rate we would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term in a similar economic environment. We considered the rates we paid in previous financing and sale-leaseback transactions, the rates on our borrowings under our prior secured revolving credit facility and mortgage rates on commercial properties for various terms in developing our incremental borrowing rates.

Since we did not restate prior periods as part of adopting this guidance, our results for 2019 are not directly comparable to our results for periods before January 1, 2019. Specifically, payments on our failed sale-leaseback obligations were characterized as principal and interest expense in periods prior to January 1, 2019. Beginning on January 1, 2019, these payments are characterized as rent expense and thus reduce gross profit and operating income (primarily from the Wholesale segment) relative to the results reported for periods prior to January 1, 2019.

See Notes 13, 15 and 24 for additional information.

ASC 842 requires leases be evaluated and classified as either operating or finance for financial reporting purposes. The lease term used for lease evaluation includes option periods only in instances in which the exercise of the option period is reasonably certain. Generally, lease payments are expensed on a straight-line basis over the term of the lease including renewal periods that are reasonably certain at the inception of the lease. In addition to these lease payments, certain leases require additional contingent payments based on sales volume or future inflation, which are expensed as incurred.

Income Taxes

Our wholly owned taxable subsidiaries recognize deferred income tax assets and liabilities for the expected future income tax consequences of temporary differences between financial statement carrying amounts and the related income tax basis.

Income tax attributable to our earnings and losses, excluding the earnings and losses of our wholly owned taxable subsidiaries, are assessed at the individual level of the unitholder. Accordingly, we do not record a provision for income taxes other than for those earnings and losses generated or incurred by our wholly owned taxable subsidiaries.

Tax positions not meeting the more-likely-than-not recognition threshold at the financial statement date may not be recognized or continue to be recognized under the accounting guidance for income taxes. Where required, we recognize interest and penalties for uncertain tax positions in income taxes.

Valuation allowances are initially recorded and reevaluated each reporting period by assessing the likelihood of the ultimate realization of a deferred tax asset. Management considers a number of factors in assessing the realization of a deferred tax asset, including the reversal of temporary differences, projections of future taxable income and ongoing prudent and feasible tax planning strategies. The amount of deferred tax assets ultimately realized may differ materially from the estimates utilized in the computation of valuation allowances and may materially impact the financial statements in the future.

Earnings Per Common Unit

Earnings per Common Unit

In addition to the common units, we have identified the IDRs as participating securities and compute income per unit using the two-class method under which any excess of distributions declared over net income shall be allocated to the partners based on their respective sharing of income specified in the Partnership Agreement. Net income per common unit applicable to limited partners is computed by dividing the limited partners’ interest in net income, after deducting any incentive distributions, by the weighted-average number of outstanding common units.

See Note 23 for disclosure regarding the elimination of the IDRs, which closed on February 6, 2020.

Interest Rate Swap Contracts

Commencing in March 2020, the Partnership started to use interest rate swap contracts to reduce its exposure to unfavorable changes in interest rates. The Partnership accounts for derivative contracts in accordance with ASC Topic 815, “Derivatives and Hedging,” and recognizes derivative instruments as either assets or liabilities on the balance sheet and measures those instruments at fair value. The changes in fair value of the derivative transactions are presented in accumulated other comprehensive income and reclassified to interest expense as the interest payments on our credit facility are made.

The portion of derivative positions that are anticipated to settle within a year are included in other current assets and accrued expenses and other current liabilities, while the portion of derivative positions that are anticipated to settle beyond a year are recorded in other assets or other long-term liabilities.

Cash inflows and outflows related to derivative instruments are included as a component of operating activities on the statements of cash flows, consistent with the classification of the hedged interest payments on our credit facility.

See Note 14 for information related to our interest rate swap contracts.

New Accounting Guidance Pending Adopted

New Accounting Guidance Pending Adoption

Simplifying the Accounting for Income Taxes

In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes.” The amendments in this Update simplify the accounting for income taxes by removing certain exceptions to the general principles in ASC 740. The amendments also improve consistent application of and simplify GAAP for other areas of ASC 740 by clarifying and amending existing guidance, such as the accounting for a franchise tax (or similar tax) that is partially based on income. This standard was effective January 1, 2021 for the Partnership. The impact of adopting this guidance was not material.

Concentration Risks

For 2019 and 2018, we distributed approximately 8% and 11% of our total wholesale distribution volume to Dunne Manning Stores LLC (DMS), an entity associated with the family of a member of the Board and DMS accounted for approximately 7% and 15% of our rental income, respectively. See Note 5 for information regarding the termination of leases with DMS in connection with the acquisition of retail and wholesale assets.

For 2019 and 2018, we distributed 6% and 7% of our total wholesale distribution volume to Circle K retail sites and received 14% and 20% of our rental income from Circle K, respectively.

For more information regarding transactions with DMS and its affiliates and Circle K, see Note 16.

Approximately 12% of our rent income for 2020 was from one multi-site operator.

In 2020, our wholesale business purchased approximately 29%, 22%, 13% and 10% of its motor fuel from ExxonMobil, BP, Motiva and Marathon, respectively. In 2019, our wholesale business purchased approximately 26%, 22%, 15% and 12% of its motor fuel from ExxonMobil, BP, Circle K and Motiva, respectively. In 2018, our wholesale business purchased approximately 26%, 26%, 13% and 10% of its motor fuel from ExxonMobil, BP, Motiva and Circle K, respectively. No other fuel suppliers accounted for 10% or more of our motor fuel purchases during 2020, 2019 or 2018.

Approximately 16% of our motor fuel gallons sold was delivered by one carrier.

COVID-19 Pandemic

During the first quarter of 2020, an outbreak of a novel strain of coronavirus spread worldwide, including to the U.S., posing public health risks that have reached pandemic proportions.

We experienced a sharp decrease in fuel volume in mid-to-late March. Although fuel volumes recovered during the second half of 2020, they remain below historical levels. For 2020, the negative impact of the volume decrease on fuel gross profit was partially offset by the positive impact from the decline in crude prices, which increased DTW margins.

As a result of the implications of COVID-19, we assessed property and equipment, other long-lived assets and goodwill for impairment and concluded no assets were impaired as of March 31, 2020. No indicators of impairment stemming from the COVID-19 Pandemic have been identified since. See Note 9 for information regarding impairment charges related primarily to classifying sites as assets held for sale.

We cannot predict the scope and severity with which COVID-19 will impact our business, financial condition, results of operations and cash flows. Sustained decreases in fuel volume or erosion of margin could have a material adverse effect on our results of operations, cash flow, financial position and ultimately our ability to pay distributions.
