Note 1. DESCRIPTION OF BUSINESS

Couche- Tard and CST Merger

CST entered into the Merger Agreement dated as of August 21, 2016, with Circle K and Merger Sub. On June 28, 2017, Merger Sub merged with and into CST, at which time the separate corporate existence of Merger Sub ceased, and CST survived the Merger as an indirect, wholly owned subsidiary of Circle K. Circle K is a wholly owned subsidiary of Couche-Tard.

As a result of the Merger, Circle K indirectly owns all of the membership interests in the sole member of our General Partner, as well as a 21.1% limited partner interest in the Partnership and all of the IDRs of the Partnership. Circle K, through its indirect ownership interest in the sole member of our General Partner, has the ability to appoint all of the members of the Board and to control and manage our operations and activities.

Description of Business

Our business consists of:

•

the wholesale distribution of motor fuels;

•

the retail distribution of motor fuels to end customers at retail sites operated by commission agents or us;

•

the owning or leasing of retail sites used in the retail distribution of motor fuels and, in turn, generating rental income from the lease or sublease of the retail sites; and

•

the operation of retail sites.

The financial statements reflect the consolidated results of the Partnership and its wholly owned subsidiaries. Our primary operations are conducted by the following consolidated wholly owned subsidiaries:

•

LGW, which distributes motor fuels on a wholesale basis and generates qualified income under Section 7704(d) of the Internal Revenue Code;

•

LGPR, which functions as our real estate holding company and holds assets that generate qualified rental income under Section 7704(d) of the Internal Revenue Code; and

•

LGWS, which owns and leases (or leases and sub-leases) real estate and personal property used in the retail distribution of motor fuels, as well as provides maintenance and other services to its customers. In addition, LGWS distributes motor fuels on a retail basis and sells convenience merchandise items to end customers at company operated retail sites and sells motor fuel on a retail basis at sites operated by commission agents. Income from LGWS generally is not qualifying income under Section 7704(d) of the Internal Revenue Code.

In 2015, we issued our common units as consideration in the purchase of equity interests in CST Fuel Supply and the real property associated with certain of CST’s NTI retail sites. In addition, we also issued, and may continue to issue, common units as payment to Circle K for charges and expenses incurred by us under the Amended Omnibus Agreement. There is no obligation for Circle K to accept common units representing limited partner interests in lieu of cash for amounts due under the Amended Omnibus Agreement. CST also acquired our common units through open market purchases from September 2015 through December 2015. At December 31, 2017, Circle K indirectly owned 21.1% of our limited partner interests.

Significant Accounting Policies [Abstract]
Significant Accounting Policies	Note 2. SIGNIFICANT ACCOUNTING POLICIES 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 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 Accounts receivable primarily result from the sales of motor fuels to customers and rental fees for retail sites. The majority of our accounts receivable relate to our motor fuel sales that can generally be described as high volume and low margin activities. Credit is extended to a customer based on an evaluation of the customer’s financial condition. In certain circumstances collateral may be required from the customer. Receivables are recorded at face value, without interest or discount. Receivables include amounts due from financial institutions for customer credit and debit card transactions. The provision for bad debts is generally based upon a specific analysis of aged accounts while also factoring in any new business conditions that might impact the historical analysis, such as market conditions and bankruptcies of particular customers. Bad debt provisions are included in selling, general and administrative expenses. We review all accounts receivable balances on at least a quarterly basis and provide an allowance for doubtful accounts based on historical experience and on a specific identification 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. Food and merchandise inventory is valued at the lower of average cost or net realizable value using the first-in, first-out method, net of a reserve for potentially obsolete or slow-moving inventory. 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. Asset Acquisitions and Business Combinations We early adopted ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, effective January 1, 2017. Under this guidance, we 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 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 these items 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. See Note 3 for additional information on our acquisitions. 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 five 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, wholesale fuel distribution rights and trademarks are amortized over 10 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 are amortized over the applicable lease term. Intangible assets with definite 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 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. We early adopted ASU 2017-04, Intangibles–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, effective January 1, 2017. 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. 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 21 for additional information. Revenue Recognition Revenues from the delivery of motor fuel are recorded upon 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. 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. 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 account for leases in accordance with ASC 840–Leases. We lease certain retail sites from third parties under long-term arrangements with various expiration dates. U.S. GAAP requires leases be evaluated and classified as either operating or capital 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 can be reasonably assured and failure to exercise such options would result in an economic penalty. Minimum lease payments are expensed on a straight-line basis over the term of the lease including renewal periods that are reasonably assured at the inception of the lease. In addition to minimum lease payments, certain leases require additional contingent payments based on sales volume or future inflation. 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 or the lease agreement has a repurchase feature, the sale-leaseback arrangements are accounted for as financing transactions. 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 In addition to the common and subordinated 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 (including common and subordinated unitholders) is computed by dividing the limited partners’ interest in net income, after deducting any incentive distributions, by the weighted-average number of outstanding common and subordinated units. As discussed in Note 17, all subordinated units converted to common units in the first quarter of 2016. New Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09–Revenue from Contracts with Customers (Topic 606), which results in comprehensive new revenue accounting guidance, requires enhanced disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized, and develops a common revenue standard under U.S. GAAP and International Financial Reporting Standards. Specifically, 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 was effective January 1, 2018 and we applied the modified retrospective method of adoption. We have completed our assessment and have not identified any material impact on the financial statements, although it will affect disclosures. This guidance applies to over 90% of our revenues as the only primary revenue stream outside the scope of this guidance is rental income. In February 2016, the FASB issued ASU 2016-02–Leases (Topic 842). This standard modifies existing guidance for reporting organizations that enter into leases to increase transparency by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 is effective for fiscal years and interim periods within those years beginning after December 15, 2018, and requires a modified retrospective approach to adoption. Early adoption is permitted. Management continues to evaluate the impact of this new guidance, but the adoption will have a material impact on our balance sheet as we will be required to recognize right-of-use assets and lease liabilities for operating leases. We will not adopt this guidance early. We intend to apply each of the practical expedients in adopting this new guidance. In October 2016, the FASB issued ASU 2016-16–Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. This standard requires companies to account for income tax effects of intercompany transactions other than inventory in the period in which the transfer occurs rather than when the assets are transferred outside of the consolidated entity. We have chosen to early adopt the standard effective January 1, 2017, which had no impact as of the date of adoption but could apply to future intra-entity transactions and require us to recognize the income tax effects of those transactions in the period in which the transfer occurs. In January 2017, the FASB issued ASU 2017-01–Business Combinations (Topic 805): Clarifying the Definition of a Business. This standard clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. We early adopted this standard effective January 1, 2017. Although there was no impact upon adoption, among other things, this guidance results in the capitalization rather than expensing of acquisition costs in transactions that are accounted for as asset acquisitions rather than business combinations under the new definition of a business. In January 2017, the FASB issued ASU 2017-04–Intangibles–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This standard removes Step 2 of the goodwill impairment test. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Management early adopted this guidance effective January 1, 2017, which had no impact upon adoption but could result in a change in the measurement of an impairment loss if an impairment was required to be recorded in the future. Certain other new financial accounting pronouncements have become effective for our financial statements and the adoption of these pronouncements will not affect our financial position or results of operations, nor will they require any additional disclosures. Concentration Risk For 2017, 2016 and 2015, we distributed approximately 13%, 16% and 17% of our total wholesale distribution volume to Dunne Manning Stores LLC, an entity associated with the family of a member of the Board (DMS) and DMS accounted for approximately 22%, 26% and 36% of our rental income, respectively. For 2017, 2016 and 2015, we distributed 8%, 8% and 7% of our total wholesale distribution volume to CST retail sites that are not supplied by CST Fuel Supply and received 20%, 21% and 17% of our rental income from CST, respectively. For more information regarding transactions with DMS and its affiliates and CST, see Note 12. In 2017, our wholesale business purchased approximately 28%, 27% and 16% of its motor fuel from ExxonMobil, BP and Motiva, respectively. In 2016, our wholesale business purchased approximately 30%, 25% and 24% of its motor fuel from ExxonMobil, BP and Motiva, respectively. In 2015, our wholesale business purchased approximately 30%, 26% and 26% of its motor fuel from ExxonMobil, BP and Motiva, respectively. No other fuel suppliers accounted for 10% or more of our motor fuel purchases during 2017, 2016 or 2015. Valero supplied substantially all of the motor fuel purchased by CST Fuel Supply during all periods presented. CST Fuel Supply purchased approximately 1.7 billion, 1.8 billion and 1.9 billion gallons of motor fuel from Valero for 2017, 2016 and 2015, respectively.

Acquisitions

Note 3. ACQUISITIONS

Jet-Pep Assets Acquisition

On November 28, 2017, we closed on the acquisition of the real property and the fuel supply business of 101 commission operated retail sites, including 92 fee simple sites, the leasehold interest in five real property sites and the fuel supply business to four independent commission sites, all located in Alabama, from Jet-Pep, Inc. and affiliated entities, for aggregate cash consideration of $75.6 million, including the value of the motor fuel inventory contained in the retail sites and net of the assumption of certain liabilities. On the same day, Circle K closed on the acquisition of certain related retail and terminal assets from Jet-Pep, Inc. and affiliated entities.

The set of assets acquired did not meet the definition of a business under ASU 2017-01, and as such, this transaction was accounted for as an asset acquisition. The values ascribed to the assets acquired and liabilities assumed on the date of acquisition were as follows (in thousands):

Current assets (excluding cash and inventories)	$	263
Inventories		3,294
Assets held for sale		2,030
Property and equipment		63,450
Intangible assets		11,174
Accrued expenses and other current liabilities		(59	)
Asset retirement obligations		(3,275	)
Other noncurrent liabilities		(1,250	)
Total consideration	$	75,627

The value of land was based on a market approach. The value of buildings and equipment was based on a cost approach. The buildings and equipment are being depreciated on a straight-line basis, with estimated remaining useful lives of 20 years for the buildings and five to 10 years for equipment.

The $9.2 million value of the wholesale fuel distribution rights included in intangibles was based on an income approach and management believes the level and timing of cash flows represent relevant market participant assumptions. The wholesale fuel distribution rights are being amortized on a straight-line basis over an estimated useful life of approximately 10 years.

The $0.5 million value of the wholesale fuel supply agreements was based on an income approach, and management believes the level and timing of cash flows represent relevant market participant assumptions. The wholesale fuel supply agreements are being amortized on an accelerated basis over an estimated useful life of approximately 10 years.

The $1.0 million value of the trademarks was based on an income approach using the present value of incremental after-tax cash flows attributable solely to the trademark.

The $0.5 million value of the covenant not to compete was based on an income approach using the difference between the present value of after-tax cash flows with and without the covenant not to compete in place. The covenant not to compete intangible asset is being amortized on a straight-line basis over a 5-year period.

Operating revenues since the date of acquisition were $15.5 million for the year ended December 31, 2017.

Acquisition of State Oil Assets

On September 27, 2016, we closed on the acquisition of 57 controlled retail sites (56 fee sites and one leased site) and certain other assets of State Oil Company, being operated as 55 lessee dealer accounts and two non-fuel tenant locations, as well as 25 independent dealer accounts located in the greater Chicago market for approximately $41.9 million, including working capital.

In December 2016, we sold 17 of these retail sites. See Note 10 for additional information.

Acquisition of Franchised Holiday Stores

On March 29, 2016, we closed on the acquisition of 31 Franchised Holiday Stores and three liquor stores from S/S/G Corporation for approximately $52.4 million, including working capital. Of the 34 stores, 31 are located in Wisconsin and three are located in Minnesota. The acquisition was funded by borrowings under our credit facility.

Purchase of Wholesale Fuel Supply Contracts from CST

In February 2016, we purchased 21 independent dealer contracts and 11 sub-wholesaler contracts from CST for $2.9 million. See Note 12 for additional information.

Note 4. ASSETS HELD FOR SALE

We have classified 12 and four sites as held for sale at December 31, 2017 and December 31, 2016. Of the sites held for sale at December 31, 2017, 11 are required to be divested per an FTC order in connection with Couche-Tard’s acquisition of Holiday Stationstores, Inc. and the joint acquisition of Jet-Pep Assets by Couche-Tard and us. These assets are expected to be sold in 2018. Assets held for sale were as follows (in thousands):

Total		13,216			2,638
Less accumulated depreciation		(1,508	)		(527	)
Assets held for sale	$	11,708		$	2,111

During 2017, as approved by the independent conflicts committee of our Board, we sold 29 properties to Dunne Manning Realty LP, an entity affiliated with a member of the Board (DMR), for $18.9 million, resulting in a $0.8 million gain. These sites were generally sites at which we did not supply fuel or represented vacant land. See Note 12 for additional information.

During 2017, we sold two properties as a result of the FTC’s requirements associated with the Merger for $6.7 million, resulting in a gain of $2.2 million. In addition, Circle K agreed to reimburse us for the tax liability incurred on the required sale, resulting in additional proceeds of $0.3 million, which was accounted for as a contribution to partners’ capital. See Note 12 for additional information.

During 2017, DMS renewed its contract with one of its customers, triggering a $0.8 million earn-out payment by DMS to us under a contract entered into with DMS at the time of CST acquiring our General Partner in October 2014, which was recorded as a gain. See Note 12 for additional information.

Approximately $601.3 million of property and equipment, net was used for leasing purposes at December 31, 2017.

We are the lessee in certain sale-leaseback transactions for certain retail sites, and because we have continuing involvement in the underlying retail sites, or the lease agreement has a repurchase feature, the sale-leaseback arrangements are accounted for as lease financing obligations. The table above includes these retail sites, as well as certain leases accounted for as capital leases. The total cost and accumulated amortization of property and equipment recorded by us under sale leaseback transactions and capital leases was $103.0 million and $30.6 million, respectively, at December 31, 2017 and $101.0 million and $23.9 million, respectively, at December 31, 2016.

See Note 11 for future minimum rental payments on capital lease obligations and Note 10 for future minimum rental payments on sale-leaseback obligations.

Depreciation expense, including amortization of assets recorded under sale-leasebacks and capital lease obligations, was approximately $42.5 million, $39.5 million and $33.7 million for 2017, 2016 and 2015, respectively. These amounts include impairments primarily recorded when sites were classified as assets held for sale amounting to $1.3 million, $1.1 million and $0.4 million for 2017, 2016 and 2015, respectively.

Intangible assets associated with wholesale fuel supply contracts/rights are amortized over 10 years using either an accelerated or straight-line amortization method as appropriate. Trademarks are amortized over five 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 are amortized over the applicable lease term.

Amortization expense, including amortization of above and below market lease intangible assets, which is classified as rent expense, was $13.7 million, $13.7 million and $13.4 million for the years ended December 31, 2017, 2016 and 2015, respectively. Aggregate amortization expense is expected to be $14.8 million, $12.4 million, $12.1 million, $11.5 million and $10.7 million for the years ending December 31, 2018, 2019, 2020, 2021 and 2022, respectively.

Our business strategy includes the conversion of retail sites from company operated retail sites to lessee dealers. As a result of these conversions, there is a reduction in future cash flows in the Retail segment and an expected increase in future cash flows that will be received by the Wholesale segment subsequent to the date of conversion. The effect of these conversions during 2016 was a $6.5 million reassignment of goodwill originally assigned to the Retail segment to the Wholesale segment. There was no reassignment during 2017.

Sale Leaseback Obligations

We are the lessee in certain sale-leaseback transactions for certain retail sites that expire through 2032, and as we have continuing involvement in the underlying retail sites through a sublease with a lessee dealer or the lease agreement has a repurchase feature, the sale-leaseback arrangements are accounted for as lease financing obligations. In lieu of recognizing rent expense for the lease rental payments, we record interest expense, which amounted to $3.9 million, $3.3 million and $2.4 million for 2017, 2016 and 2015, respectively.

Renegotiation of Rocky Top Purchase Obligation

In connection with the Rocky Top acquisition completed in September 2013, we entered into a deferred seller financing arrangement, which obligated us to purchase certain retail sites over a 5-year period for an average of $5.2 million per year beginning in 2016 at an approximately 7.7% capitalization rate. In June 2016, we renegotiated the terms with the sellers, eliminating the deferred seller financing obligation and agreeing to terms of a new lease of the assets for an initial term of 15 years and eight months with four renewal options of five years each. Under this triple net lease, annual rent is initially $1.8 million based on a 6.5% capitalization rate and increases 1.5% per year. However, because of the continuing involvement we have with the retail sites through the lease and sublease of the properties, we recorded the liability on our balance sheet at fair value in June 2016, which approximated its carrying value. These lease financing obligations are classified within accrued expenses and other current liabilities and other noncurrent liabilities on the consolidated balance sheet.

Sale Leaseback Transaction

In December 2016, we sold the real property at 17 retail sites acquired through the State Oil Assets acquisition for cash proceeds of $25.0 million, which were used to repay borrowings on the credit facility. We lease these properties for an initial term of 15 years with three renewal options of approximately five years each. Under the triple net lease, annual rent is initially $1.6 million based on a 6.5% capitalization rate and increases every five years based on inflation. Because of the continuing involvement we have with the retail sites through the lease and sublease of the properties, we recorded a liability for the proceeds received and are amortizing this liability over the lease term as rent payments are made.

Asset Retirement Obligations

Environmental laws in the U.S. require the permanent closure of USTs within one to two years after the USTs are no longer in service, depending on the jurisdiction in which the USTs are located. We have estimated that USTs at our owned retail sites will remain in service approximately 30 years and that we will have an obligation to remove those USTs at that time. For our leased retail sites, our lease agreements generally require that we remove certain improvements, primarily USTs and signage, upon termination of the lease, and so an asset retirement obligation is incurred upon entering the lease. There are no assets that are legally restricted for purposes of settling our asset retirement obligations.

Credit Facility

The credit facility is a senior secured revolving credit facility maturing on March 4, 2019, with a total borrowing capacity of $550.0 million, under which swing-line loans may be drawn up to $25.0 million and standby letters of credit may be issued up to an aggregate of $45.0 million. The credit facility may be increased, from time to time, upon our written request, subject to certain conditions, up to an additional $100.0 million. Letters of credit outstanding at December 31, 2017 and 2016 totaled $6.7 million and $6.5 million, respectively. The amount of availability at December 31, 2017 under the revolving credit facility, after taking into account outstanding letters of credit and debt covenant constraints, was $37.3 million. In connection with future acquisitions, the revolving credit facility requires, among other things that we have, after giving effect to such acquisition, at least $20.0 million, in the aggregate, of borrowing availability under the revolving credit facility and unrestricted cash on the balance sheet on the date of such acquisition. All obligations under the credit facility are secured by substantially all of the assets of the Partnership and its subsidiaries.

Outstanding borrowings under the revolving credit facility bear interest at LIBOR plus an applicable margin, which was 3.00% at December 31, 2017. Our borrowings had a weighted-average interest rate of 4.44% at December 31, 2017.

We are required to comply with certain financial covenants under the credit facility. We are required to maintain a total leverage ratio (as defined in the credit facility) for the most recently completed four fiscal quarters of less than or equal to 4.50 : 1.00, except for periods following a material acquisition, generally defined as an acquisition with a purchase price of at least $30.0 million. The total leverage ratio shall not exceed 5.00 : 1.00 for the quarter in which a material acquisition closes and the first three full fiscal quarters following the closing of a material acquisition. If we issued Qualified Senior Notes (as defined in the credit facility) in the aggregate principal amount of $175.0 million or greater, the ratio shall not exceed 5.50 : 1.00. If we issued Qualified Senior Notes of $175.0 million or greater, we are also required to maintain a senior leverage ratio (as defined in the credit facility) of less than or equal to 3.00 : 1.00 and a consolidated interest coverage ratio (as defined in the credit facility) of at least 2.75 : 1.00. As of December 31, 2017, we were in compliance with these financial covenants.

The credit facility prohibits us from making distributions to our unitholders if any potential default or event of default occurs or would result from the distribution, or we are not in compliance with our financial covenants. In addition, the credit facility contains various covenants which may limit, among other things, our ability to grant liens; create, incur, assume, or suffer to exist other indebtedness; or make any material change to the nature of our business, including mergers, liquidations, and dissolutions; and make certain investments, acquisitions or dispositions.

Note Payable

In connection with a June 2013 acquisition of certain retail sites in Florida, we issued a $1.0 million note payable with interest at 4.0%. The note matures July 1, 2018, at which time a balloon payment for all outstanding principal and any unpaid interest is due. The loan is secured by all the real and personal property at these retail sites.

Capital Lease Obligations

In May 2012, the Predecessor Entities entered into a 15-year master lease agreement with renewal options of up to an additional 20 years with Getty. Pursuant to the lease, the Predecessor Entities originally leased 105 retail sites in Massachusetts, New Hampshire and Maine. The lease was assigned to the Partnership. In December 2012, the agreement was amended to add an additional 25 retail sites in New Jersey. Since then, the agreement has been amended from time to time to add an insignificant number of additional retail sites. We pay fixed rent, which increases 1.5% per year. In addition, the lease requires contingent rent payments based on gallons of motor fuel sold.

Because the fair value of the land at lease inception was estimated to represent more than 25% of the total fair value of the real property subject to the lease, the land element of the lease was analyzed for operating or capital treatment separately from the rest of the property subject to the lease. The land element of the lease was classified as an operating lease and all of the other property was classified as a capital lease. As such, future minimum lease payments are included in both the capital lease obligations table above as well as the operating lease table in Notes 11 and 13.

Through December 31, 2017, certain retail sites have been terminated from the lease. Any property and equipment or capital lease obligations associated with these retail sites were removed from the balance sheet.

Transactions with Circle K

Fuel Sales and Rental Income

We sell wholesale motor fuel under a master fuel distribution agreement to 49 Circle K retail sites and lease real property on 73 retail sites to Circle K under a master lease agreement each having initial 10-year terms. The fuel distribution agreement provides us with a fixed wholesale mark-up per gallon. The master lease agreement is a triple net lease.

Revenues from wholesale fuel sales and real property rental income from CST and Circle K were as follows (in thousands):

	For the Year Ended December 31,
	2017		2016		2015
Revenues from motor fuel sales to CST and Circle K	$	136,649	$	118,745	$	135,813
Rental income from CST and Circle K		17,021		17,188		11,422

Accounts receivable from Circle K for fuel amounted to $3.9 million and $3.2 million at December 31, 2017 and December 31, 2016, respectively.

Amended Omnibus Agreement and Management Fees

We incurred $13.9 million, $15.9 million and $15.3 million for 2017, 2016 and 2015, respectively, including incentive compensation costs and non-cash stock-based compensation expense under the Amended Omnibus Agreement, which are recorded as a component of operating expenses and general and administrative expenses in the statement of income. Amounts payable to Circle K and CST were $25.3 million and $10.0 million at December 31, 2017 and December 31, 2016, respectively. The amounts payable at December 31, 2017 include separation benefits associated with the Merger and equity compensation expense associated with CST stock-based awards. See Note 24 for additional information.

Common Units Issued to CST and Circle K as Consideration for Amounts due Under the Amended Omnibus Agreement

As approved by the independent conflicts committee of the Board, the Partnership, CST and Circle K mutually agreed to settle, from time to time, some or all of the amounts due under the terms of the Amended Omnibus Agreement in newly issued common units representing limited partner interests in the Partnership. We issued the following common units to CST or Circle K as consideration for amounts due under the terms of the Amended Omnibus Agreement:

Year	Number of Common Units Issued
2015		259,312
2016		440,266
2017		550,516

Circle K will receive 136,882 common units on March 1, 2018 as a portion of the payment for the management fees for the fourth quarter of 2017.

CST Fuel Supply Equity Interests

CST Fuel Supply provides wholesale motor fuel distribution to the majority of CST’s legacy U.S. retail sites at cost plus a fixed markup per gallon. We owned a 17.5% total interest in CST Fuel Supply at December 31, 2017 and 2016. We account for the income derived from our equity interest of CST Fuel Supply as “Income from CST Fuel Supply equity interests” on our statement of income, which amounted to $14.9 million, $16.0 million and $10.5 million for 2017, 2016 and 2015, respectively. Accounts receivable from Circle K and CST related to this income amounted to $1.2 million at December 31, 2017 and December 31, 2016.

In connection with the Merger, the FTC approved a final order requiring the divestiture of certain CST retail fuel stations. As a result, in September 2017, 61 sites were sold to a third party and removed from the fuel distribution agreement between CST Marketing and Supply and CST Services. CST Marketing and Supply no longer supplies fuel to such sites. To compensate for the decrease in the amount of motor fuels sold by CST Marketing and Supply, Circle K agreed to purchase at least 114.9 million gallons annually (the “Annual Commitment”) in addition to the volumes continued to be sold under the fuel distribution agreement to retail fuel stations that remain with Circle K after the divestiture. In addition, should Circle-K fail to purchase all or a portion of the Annual Commitment, Circle K has agreed to make monthly payments to CST Marketing and Supply in the amount of the seller’s margin of $0.05 per gallon under the fuel distribution agreement multiplied by the number of gallons not physically sold pursuant to the Annual Commitment. Consequently, the Partnership, by virtue of its 17.5% ownership interest in CST Fuel Supply, the 100% owner of CST Marketing and Supply, will continue to receive its share from the volumes sold to the 61 retail sites prior to the FTC mandated divestiture. This agreement continues until the fuel distribution agreement between CST Marketing and Supply and CST Services is terminated, which had an initial term of 10 years expiring in December 2024.

In July 2016, CST provided a refund payment to us related to our 17.5% interest in CST Fuel Supply resulting from the sale by CST of 79 retail sites in California and Wyoming to 7-Eleven, Inc. and its wholly-owned subsidiary, SEI Fuel Services, Inc., to which CST Fuel Supply no longer supplies motor fuel. The purpose of the refund payment was to make us whole for the decrease in the value of our interest in CST Fuel Supply arising from sales volume decreases. The total refund payment received by us, as approved by the independent conflicts committee of the Board, was approximately $18.2 million ($17.5 million in cash with the remainder in our common units owned by CST) and was accounted for as a contribution to equity.

Purchase of Fuel from CST and Circle K

We purchase the fuel supplied to 32 retail sites from CST Fuel Supply of which we own a 17.5% interest, and resell the wholesale motor fuel to independent dealers and sub-wholesalers. We purchased $23.8 million and $20.4 million of motor fuel from CST Fuel Supply for the year ended December 31, 2017 and 2016, respectively, in connection with these retail sites.

We also purchase the fuel supplied to 101 retail sites acquired in the Jet-Pep Assets acquisition from a terminal owned and operated by Circle K. We purchased $11.3 million of motor fuel from Circle K in 2017.

Circle K acquired Holiday Stationstores, Inc. (Holiday) on December 15, 2017. Prior to that acquisition, we were a franchisee of Holiday (Franchised Holiday Stores), purchased fuel from Holiday and paid a franchise fee to Holiday. As a result of Circle K’s acquisition, we purchase fuel from Circle K to supply our Holiday-branded sites. For 2017, these purchases amounted to $1.9 million. We also pay a franchise fee to Circle K, which for 2017 was insignificant.

IDR and Common Unit Distributions

We distributed $4.3 million, $3.4 million and $1.4 million to CST or Circle K related to its ownership of our IDRs and $17.0 million, $15.5 million and $8.1 million related to its ownership of our common units during 2017, 2016 and 2015, respectively.

Income Tax Reimbursement

As discussed in Note 4, we sold two properties during the year ended December 31, 2017 as a result of the FTC’s requirements associated with Couche-Tard’s acquisition of CST. Circle K agreed to reimburse us for the tax liability incurred on the required sale, resulting in additional proceeds of $0.3 million, which was accounted for as a contribution to partners’ capital.

Wholesale Motor Fuel Sales and Real Estate Rentals

Revenues from motor fuel sales and rental income from DMS and its affiliates were as follows (in thousands):

	For the Year Ended December 31,

Revenue from rental income from Topstar Enterprises, an entity affiliated with a member of the Board, was $0.5 million for 2017, 2016 and 2015.

We lease real estate from certain entities affiliated with Joseph V. Topper, Jr., director of the Board. Rent expense paid to these entities was $0.9 million for 2017, 2016 and 2015.

As discussed in Note 4, DMS renewed its contract with one of its customers, triggering a $0.8 million earn-out payment by DMS to us under a contract entered into with DMS at the time of CST acquiring our General Partner in October 2014.

Also as discussed in Note 4, we sold 29 properties to DMR during 2017 for $18.9 million, resulting in a gain of $0.8 million.

Maintenance and Environmental Costs

Certain maintenance and environmental monitoring and remediation activities are performed by an entity affiliated with Joseph V. Topper, Jr., a member of the Board, as approved by the independent conflicts committee of the Board. We incurred charges with this related party of $1.5 million, $1.6 million and $1.3 million for 2017, 2016 and 2015, respectively. Accounts payable to this related party amounted to $0.2 million at December 31, 2017.

Aircraft Usage Costs

From time to time, we lease, on a non-exclusive basis, aircraft owned by a group of individuals that includes Joseph V. Topper, Jr. and John B. Reilly, III, members of our Board, as previously approved in August 2013 by the independent conflicts committee of the Board. We incurred $0.2 million for 2015.

Principal Executive Offices

Our principal executive offices are in Allentown, Pennsylvania. We sublease office space from Circle K that Circle K leases from an affiliate of John B. Reilly, III and Joseph V. Topper, Jr., members of our Board. The management fee charged by Circle K to us under the Amended Omnibus Agreement incorporates this rental expense, which amounted to $0.7 million, $0.6 million and $0.3 million for 2017, 2016 and 2015, respectively.

Public Relations and Website Consulting Services

We have engaged a company affiliated with a member of the Board for public relations and website consulting services. The cost of these services amounted to $0.1 million for 2017, 2016 and 2015.

Environmental Matters

Note 14. ENVIRONMENTAL MATTERS

We currently own or lease retail sites where refined petroleum products are being or have been handled. These retail sites and the refined petroleum products handled thereon may be subject to federal and state environmental laws and regulations. Under such laws and regulations, we could be required to remove or remediate containerized hazardous liquids or associated generated wastes (including wastes disposed of or abandoned by prior owners or operators), to remediate contaminated property arising from the release of liquids or wastes into the environment, including contaminated groundwater, or to implement best management practices to prevent future contamination.

We maintain insurance of various types with varying levels of coverage that is considered adequate under the circumstances to cover operations and properties. The insurance policies are subject to deductibles that are considered reasonable and not excessive. In addition, we have entered into indemnification and escrow agreements with various sellers in conjunction with several of their respective acquisitions, as further described below. Financial responsibility for environmental remediation is negotiated in connection with each acquisition transaction. In each case, an assessment is made of potential environmental liability exposure based on available information. Based on that assessment and relevant economic and risk factors, a determination is made whether to, and the extent to which we will assume liability for existing environmental conditions.

The table below presents a rollforward of our environmental liability (in thousands):

	December 31,
	2017			2016
Beginning balance	$	4,169		$	2,753
Provision for new environmental losses		1,334			199
Changes in estimates for previously incurred losses		(579	)		1,752
Payments		(1,387	)		(535	)
Total balance		3,537			4,169
Current portion, included within accrued expenses and other current liabilities		1,611			1,602
Long-term portion, included within other long-term liabilities	$	1,926		$	2,567

At December 31, 2017, we were indemnified by third-party escrow funds, state funds or insurance totaling $3.4 million, which are recorded as indemnification assets and included within other noncurrent assets on the balance sheet. State funds represent probable state reimbursement amounts. Reimbursement will depend upon the continued maintenance and solvency of the state. Insurance coverage represents amounts deemed probable of reimbursement under insurance policies.

The estimates used in these reserves are based on all known facts at the time and an assessment of the ultimate remedial action outcomes. We will adjust loss accruals as further information becomes available or circumstances change. Among the many uncertainties that impact the estimates are the necessary regulatory approvals for, and potential modifications of remediation plans, the amount of data available upon initial assessment of the impact of soil or water contamination, changes in costs associated with environmental remediation services and equipment and the possibility of existing legal claims giving rise to additional claims.

Environmental liabilities related to the sites contributed to the Partnership in connection with our IPO have not been assigned to us, and are still the responsibility of the Predecessor Entity. Under the Amended Omnibus Agreement, the Predecessor Entity must indemnify us for any costs or expenses that it incurs for environmental liabilities and third-party claims, regardless of when a claim is made, that are based on environmental conditions in existence prior to the closing of the IPO for contributed sites. As such, these environmental liabilities and indemnification assets are recorded on the balance sheet of the Predecessor Entity rather than the balance sheet of the Partnership.

Commitments And Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 15. COMMITMENTS AND CONTINGENCIES

Purchase Commitments

The future minimum volume purchase requirements under the existing supply agreements are approximate gallons, with a purchase price at prevailing market rates for wholesale distributions. We purchased approximately 928.0 million, 869.6 million and 884.6 million gallons of motor fuel under the existing supply agreements for 2017, 2016 and 2015, respectively. The following provides total annual future minimum volume purchase requirements (in thousands of gallons):

2018			346,842
2019			314,934
2020			40,729
2021			32,980
2022			32,980
Thereafter			50,000
Total			818,465

In the event for a given contract year we fail to purchase the required minimum volume, the underlying third party’s exclusive remedies (depending on the magnitude of the failure) are either termination of the supply agreement and/or a financial penalty per gallon based on the volume shortfall for the given year. We did not incur any significant penalties for the periods presented.

Litigation Matters

We are from time to time party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contract, property damages, environmental damages, employment-related claims and damages, punitive damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to all such lawsuits, claims and proceedings, we record a reserve when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. In addition, we disclose matters for which management believes a material loss is at least reasonably possible. None of these proceedings, separately or in the aggregate, are expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows. In all instances, management has assessed the matter based on current information and made a judgment concerning its potential outcome, giving due consideration to the nature of the claim, the amount and nature of damages sought and the probability of success. Management’s judgment may prove materially inaccurate, and such judgment is made subject to the known uncertainties of litigation.

We were a co-defendant, together with our General Partner, CST and CST Services, in a lawsuit brought by a former executive of CST Services who, until March 2015, provided services to us as Chief Investment Officer and Vice President of Finance (Court of Common Pleas, Lehigh County, Pennsylvania, case number 2015-1003). In connection with CST’s acquisition of our General Partner in 2014, the plaintiff alleged breach of contract and associated claims relating to his termination of employment and claimed severance benefits under the EICP. In October 2017, a jury awarded the plaintiff a total of $1.7 million. Such amount was recorded in general and administrative expenses in 2017. Under the EICP, we were also obligated to pay reasonable legal expenses incurred by the plaintiff in connection with this dispute, which we expensed as incurred. The Partnership incurred total legal fees related to this case of $0.8 million for the year ended December 31, 2017.

Fair Value Measurements	12 Months Ended
Fair Value Measurements	Dec. 31, 2017
Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 16. FAIR VALUE MEASUREMENTS General We measure and report certain financial and non-financial assets and liabilities on a fair value basis. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). U.S. GAAP specifies a three-level hierarchy that is used when measuring and disclosing fair value. The fair value hierarchy gives the highest priority to quoted prices available in active markets (i.e., observable inputs) and the lowest priority to data lacking transparency (i.e., unobservable inputs). An instrument’s categorization within the fair value hierarchy is based on the lowest level of significant input to its valuation. The following is a description of the three hierarchy levels. Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Active markets are considered to be those in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2—Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability. This category includes quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in inactive markets. Level 3—Unobservable inputs are not corroborated by market data. This category is comprised of financial and non-financial assets and liabilities whose fair value is estimated based on internally developed models or methodologies using significant inputs that are generally less readily observable from objective sources. Transfers into or out of any hierarchy level are recognized at the end of the reporting period in which the transfers occurred. There were no transfers between any levels in 2017 or 2016. As further discussed in Note 18, we have accrued for unvested phantom units and vested and unvested profits interests as a liability and adjust that liability on a recurring basis based on the market price of our common units each balance sheet date. Such fair value measurements are deemed Level 1 measurements. Financial Instruments The fair value of our accounts receivable, notes receivable, and accounts payable approximated their carrying values as of December 31, 2017 and 2016 due to the short-term maturity of these instruments. The fair value of the revolving credit facility approximated its carrying values of $506.0 million as of December 31, 2017 and $441.5 million as of December 31, 2016, due to the frequency with which interest rates are reset and the consistency of the market spread.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

We issued common units (net of units withheld for income taxes) as a result of the vesting of phantom units and conversion of profits interests previously issued primarily to CST employees who provide services principally to CrossAmerica totaling 35,993 common units in 2017, 107,227 common units in 2016 and 90,671 common units in 2015. See Note 18 for additional information.

In January 2015, we issued 1,497,946 common units to a subsidiary of CST in connection with the acquisition of a 5% interest in CST Fuel Supply. See Note 12 for additional information.

On June 19, 2015, we closed on the sale of 4.6 million common units for net proceeds of approximately $138.5 million. On July 16, 2015, we closed on the sale of an additional 0.2 million common units for net proceeds of approximately $6.4 million in accordance with the underwriters’ option to purchase additional common units associated with the June offering. We used the net proceeds from this offering to reduce indebtedness outstanding under its revolving credit facility.

On July 1, 2015, we issued 3,303,208 of our common units to a subsidiary of CST in connection with the acquisition of an additional 12.5% equity interest in CST Fuel Supply. See Note 12 for additional information.

See Note 12 for information regarding the issuance of common units to CST and Circle K as payment of a portion of the amounts due under the terms of the Amended Omnibus Agreement.

Common Unit Repurchase Program

In November 2015, the Board approved a common unit repurchase program under Rule 10b-18 of the Exchange Act authorizing us to repurchase up to an aggregate of $25.0 million of the common units representing limited partner interests in the Partnership. Under the program, we may make purchases in the open market in accordance with Rule 10b-18 of the Exchange Act, or in privately negotiated transactions, pursuant to a trading plan under Rule 10b5-1 of the Exchange Act or otherwise. Any purchases will be funded from available cash on hand. The common unit repurchase program does not require us to acquire any specific number of our common units and may be suspended or terminated by us at any time without prior notice. The purchases will not be made from any officer, director or control person of the Partnership or CST. The following table shows the purchases made through December 31, 2016. No purchases were made in 2017.

Period	Total Number of Units Purchased		Average Price Paid per Unit		Total Cost of Units Purchased		Amount Remaining under the Program

CST Purchases of Common Units

On September 21, 2015, CST announced that the independent executive committee of its board of directors approved a common unit purchase program under Rule 10b-18 of the Exchange Act, authorizing CST to purchase up to an aggregate of $50 million of the common units representing limited partner interests in us. The common unit purchase program does not have a fixed expiration date and may be modified, suspended or terminated at any time at CST’s discretion.

CST made no purchases under the unit purchase program in 2016 or 2017. From inception until December 31, 2015, CST had purchased $19.8 million, or 804,667 common units, at an average price of $24.64 per common unit, which units cannot be transferred absent registration with the SEC or an available exemption from the SEC’s registration requirements.

Conversion of Subordinated Units

On February 25, 2016, the first business day after the payment of the distribution of $0.5925 per unit for the fourth quarter of 2015, the subordination period under the Partnership Agreement ended. At that time, each outstanding subordinated unit converted into one common unit and participates pro rata with the other common units in cash distributions.

Equity Based Compensation [Abstract]
Equity-Based Compensation	Note 18. EQUITY-BASED COMPENSATION Partnership Equity-Based Awards The maximum number of common units that may be delivered with respect to awards under the Plan is 1,505,000. Generally, the Plan provides for grants of restricted units, unit options, performance awards, phantom units, unit awards, unit appreciation rights, distribution equivalent rights, and other unit-based awards, with various limits and restrictions attached to these awards on a grant-by-grant basis. The Plan is administered by the Board or a committee thereof. The Board may terminate or amend the Plan at any time with respect to any common units for which a grant has not yet been made. The Board also has the right to alter or amend the Plan or any part of the Plan from time to time, including increasing the number of common units that may be granted, subject to unitholder approval as required by the exchange upon which common units are listed at that time; however, no change in any outstanding grant may be made that would adversely affect the rights of a participant with respect to awards granted to a participant prior to the effective date of such amendment or termination, except that the Board may amend any award to satisfy the requirements of Section 409A of the Internal Revenue Code. The Plan will expire on the tenth anniversary of its approval, when common units are no longer available under the Plan for grants or upon its termination by the Board, whichever occurs first. In March 2014, we contributed our investments in our operating subsidiaries and certain other assets and liabilities to LGP Operations. Since March 2014, LGP Operations granted profits interests, which are represented by Class B Units in LGP Operations. Upon vesting, Class B Unitholders will be entitled to receive cash distributions proportionate to those received by common unitholders. Class B Units are redeemable two years after they were granted, subject to certain limitations, for cash or common units at the discretion of the Board. Because the Class B Units are an interest in the equity of LGP Operations, they represent a noncontrolling interest from our perspective. As such, the Class B Units are presented as a noncontrolling interest on the balance sheet and the Class B Unitholders’ interest in the net income of LGP Operations is presented as net income attributable to noncontrolling interests on the statement of income. It is our intent to settle the phantom units upon vesting by issuing common units and to settle the profits interests upon conversion by the grantee by issuing common units. However, the awards may be settled in cash at the discretion of the Board. Under the Plan, the Partnership granted 1,233 phantom units in June 2017 to an employee of Circle K who provides services to the Partnership; such phantom units will vest in equal annual installments on the first, second and third anniversaries of the date of grant and this award was accompanied by tandem distribution equivalent rights that entitle the holder to cash payments equal to the amount of unit distributions authorized to be paid to the holders of our common units. There were no grants of equity-based awards in 2016 to employees. There are 2,620 nonvested phantom units outstanding at December 31, 2017. Since we grant awards to employees of CST who provide services to us under the Amended Omnibus Agreement, and since the grants may be settled in cash, unvested phantom units and vested and unvested profits interests receive fair value variable accounting treatment. As such, they are measured at fair value at each balance sheet reporting date and the cumulative compensation cost recognized is classified as a liability, which is included in accrued expenses and other current liabilities on the consolidated balance sheet. The balance of the accrual at December 31, 2017 and December 31, 2016 totaled $0.7 million and $1.8 million, respectively. We record equity-based compensation as a component of general and administrative expenses in the statements of income. Compensation expense for the years ended December 31, 2017, 2016 and 2015 was $0.1 million, $1.3 million and $3.0 million, respectively. The weighted average period over which compensation expense related to nonvested awards will be recognized was approximately 1.2 years as of December 31, 2017. CST Awards Before the Merger was completed, CST granted equity-based awards of approximately 47,000, 102,000 and 163,000 in the form of time vested restricted stock units of CST, stock options of CST and market share units of CST in 2017, 2016 and 2015, respectively, which were granted to certain employees of CST for services rendered on our behalf. Certain expenses associated with these awards that were charged to us under the Amended Omnibus Agreement amounted to $1.7 million, $2.3 million and $2.2 million for 2017, 2016 and 2015, respectively. At the completion of the Merger, each CST stock option, restricted stock unit and market share unit that was outstanding immediately prior to the completion of the Merger, excluding the CST restricted stock units granted in February 2017, whether vested or unvested, became fully vested and converted into the right to receive a cash payment as defined in the Merger Agreement. The Partnership was allocated a $0.4 million charge upon the accelerated vesting of these awards, included in the expense amounts for the year ended December 31, 2017 set forth above. At the completion of the Merger, each award of CST restricted stock units that was granted in February 2017 converted into the right to receive a cash payment as defined in the Merger Agreement, but such award will remain subject to the same vesting terms and payment schedule as those set forth in the original restricted stock unit award agreement; provided that such award will vest in full upon an involuntary termination of employment without cause, or termination for “Good Reason,” or termination due to death, “Disability” or “Retirement.” Unrecognized compensation expense associated with CST restricted stock units granted in February 2017 amounted to $0.7 million as of December 31, 2017, which will be recognized over the vesting term through January 2020. Awards to Members of the Board In November 2016, the Partnership granted 5,364 phantom units to non-employee directors of the Board as a portion of director compensation. Such awards vested upon the Merger. In August 2017, the Partnership granted 10,539 phantom units to non-employee directors of the Board as a portion of director compensation. Such awards vest over one year and this award was accompanied by tandem distribution equivalent rights that entitle the holder to cash payments equal to the amount of unit distributions authorized to be paid to the holders of our common units. The liability for these awards at December 31, 2017 and December 31, 2016 was not significant. The associated compensation expense was $0.2 million and $0.3 million for 2017 and 2016, respectively. The expense for 2015 was not significant.

Income Tax Disclosure [Abstract]

Income Taxes

Note 19. INCOME TAXES

As a limited partnership, we are not subject to federal and state income taxes, however our corporate subsidiaries are subject to income taxes. Income tax attributable to our taxable income, which may differ significantly from income for financial statement purposes, is assessed at the individual limited partner unit holder level. We are subject to a statutory requirement that non-qualifying income, as defined by the Internal Revenue Code, cannot exceed 10% of total gross income for the calendar year. If non-qualifying income exceeds this statutory limit, we would be taxed as a corporation. The non-qualifying income did not exceed the statutory limit in any period presented. The reported balance of our net liabilities was greater than the related tax basis of net liabilities by $3.4 million at December 31, 2017 and $9.1 million at December 31, 2016.

Certain activities that generate non-qualifying income are conducted through LGWS. LGWS is a tax paying corporate subsidiary of ours that is subject to federal and state income taxes. Current and deferred income taxes are recognized on the earnings of LGWS. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and are measured using enacted tax rates.

The Tax Cuts and Jobs Act made changes that affect us including (1) reducing the federal corporate income tax rate to 21 percent beginning January 1, 2018, and (2) providing for the immediate expensing for tax purposes for certain qualified depreciable assets placed in service after September 27, 2017. As a result of the rate change, we recognized a net tax benefit of $13.2 million due to the reduction of our net deferred tax liability.

The Tax cuts and Jobs Act also includes certain limitations on deductions effective for the tax year 2018 and forward, related to deductions for interest expense, employee compensation, and meals and entertainment. These limitations are being evaluated and may impact us. We anticipate that U.S. regulatory agencies and state governments will issue further guidance regarding the changes in deductibility which we will incorporate in our future estimates.

A valuation allowance is required when it is more likely than not that all or a portion of a deferred tax asset will not be realized. All available evidence, both positive and negative, must be considered in determining the need for a valuation allowance. The valuation allowance at December 31, 2016 related primarily to the uncertainty of the availability of future profits to realize the tax benefit of the existing deductible temporary differences. Positive evidence considered in our 2017 assessment included: 1) reversals of taxable temporary differences in future tax years; 2) an observable history of reporting taxable income; 3) projections of future taxable income; 4) feasible and prudent tax planning strategies; and 5) the impact of recently enacted tax reform. Under the Tax Cuts and Jobs Act, among other provisions, any net operating losses generated after 2017 can be carried forward indefinitely. This change, in part, allows for the consideration as a future source of taxable income, reversals of deferred tax liabilities related to indefinite lived liabilities. This income is sufficient to offset the indefinite lived asset generated by the reversals and provides additional positive evidence of future income allowing for the release of the valuation allowance. The release resulted in a tax benefit of $3.7 million.

Changes in the valuation allowance account consisted of the following (in thousands):

	For the Year Ended December 31,
	2017			2016		2015
Balance at beginning of period	$	5,495		$	5,428	$	5,675
Charged to costs and expenses (a)		(5,495	)		67		(247	)
Balance at end of period	$	—		$	5,495	$	5,428

(a)	Of the 2017 amount charged to costs and expenses, $1.8 million primarily relates to the reduction in the tax rate used to compute the valuation allowance as a result of the Tax Cuts and Jobs Act.

We provide tax reserves for federal, state and local and uncertain tax positions. The development of these tax positions requires subjective, critical estimates and judgments about tax matters, potential outcomes and timing. Although the outcome of potential tax examinations is uncertain, in management’s opinion, adequate provisions for income taxes have been made for potential liabilities resulting from these reviews. If actual outcomes differ materially from these estimates, they could have a material impact on our financial condition and results of operations. Differences between actual results and assumptions, or changes in assumptions in future periods, are recorded in the period they become known. To the extent additional information becomes available prior to resolution, such accruals are adjusted to reflect probable outcomes.

As of December 31, 2017 and 2016, we did not have unrecognized tax benefits. Our practice is to recognize interest and penalties related to income tax matters in income tax expense. We had no material interest and penalties for the years ended December 31, 2017, 2016 and 2015.

We file income tax returns with the U.S. federal government as well as the many state jurisdictions in which we operate. The statute remains open for tax years 2014 through 2017; therefore, these years remain subject to examination by federal, state and local jurisdiction authorities.

Earnings Per Share [Abstract]

Net Income Per Limited Partner Unit

Note 20. NET INCOME PER LIMITED PARTNER UNIT

Under the Partnership Agreement, a subsidiary of Circle K, as the holder of our IDRs, has an interest in distributions from us that are increasing percentages starting at 15% of quarterly distributions out of the operating surplus (as defined in our Partnership Agreement) in excess of $0.5031 per limited partner 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 as specified in the Partnership Agreement. Net income per unit applicable to limited partners is computed by dividing the limited partners’ interest in net income, after deducting the IDRs, by the weighted-average number of outstanding common units.

As discussed in Note 17, on February 25, 2016, the subordinated units converted into common units and participates pro-rata with the other common units in cash distributions.

The following tables provide a reconciliation of net income and weighted-average units used in computing basic and diluted net income per limited partner unit for the following periods (in thousands, except unit and per unit amounts):

Segment Reporting [Abstract]

Segment Reporting

Note 21. SEGMENT REPORTING

We conduct our business in two segments: 1) the Wholesale segment and 2) the Retail segment. The wholesale segment includes the wholesale distribution of motor fuel to lessee dealers, independent dealers, commission agents, DMS, Circle K and company operated retail sites. We have exclusive motor fuel distribution contracts with lessee dealers who lease the property from us. We also have exclusive distribution contracts with independent dealers to distribute motor fuel but do not collect rent from the independent dealers. Similar to lessee dealers, we have motor fuel distribution agreements with DMS and Circle K and collect rent from both. The Retail segment includes the sale of convenience merchandise items, the retail sale of motor fuel at company operated retail sites and the retail sale of motor fuel at retail sites operated by commission agents. A commission agent is a retail site where we retain title to the motor fuel inventory and sell it directly to our end user customers. At commission agent retail sites, we manage motor fuel inventory pricing and retain the gross profit on motor fuel sales, less a commission to the agent who operates the retail site. Similar to our Wholesale segment, we also generate revenues through leasing or subleasing real estate in our Retail segment.

As part of our evaluation of the economic performance of our retail sites, we will from time to time convert company owned retail sites from our Retail segment to lessee dealers in our Wholesale segment. As a result, we no longer generate revenues from the retail sale of motor fuel or merchandise at these stores subsequent to the date of conversion and we no longer incur retail operating expenses related to these retail sites. However, we continue to supply these retail sites with motor fuel on a wholesale basis pursuant to the fuel supply contract with the lessee dealer. Further, we continue to own/lease the property and earn rental income under lease/sublease agreements with the lessee dealers under triple net leases. The lessee dealer owns all motor fuel and convenience merchandise and retains all gross profit on such operating activities.

Unallocated items consist primarily of general and administrative expenses, depreciation, amortization and accretion expense, gains on sales of assets, net, and the elimination of the Retail segment’s intersegment cost of revenues from motor fuel sales against the Wholesale segment’s intersegment revenues from motor fuel sales. The profit in ending inventory generated by the intersegment motor fuel sales is also eliminated. Total assets by segment are not presented as management does not currently assess performance or allocate resources based on that data.

Separation Benefits

Note 24. SEPARATION BENEFITS

During the second quarter of 2017, the Partnership recognized a $5.4 million charge for severance and benefit costs associated with certain officers and other employees of CST Services who provided services to the Partnership and who terminated employment upon the consummation of the Merger, which constituted a change in control, as defined in the EICP and CST’s severance plans. Such costs are included in general and administrative expenses and were paid by Circle K in 2017. Accounts payable to related parties includes these costs as we will reimburse Circle K.

In addition, certain participants in the EICP received retention bonuses that will be paid in annual installments that began in July 2017 and will continue through July 2019. The Partnership recorded a $1.0 million charge during 2017 in connection with the payments made by Circle K in July 2017, which were included in general and administrative expenses. In addition, the Partnership recognized a $0.7 million charge in 2017 for the payments expected to be made in July 2018 and July 2019. The Partnership anticipates recognizing future charges totaling $0.9 million over the remaining retention period, of which $0.8 million is anticipated to be recognized in 2018.

See Note 15 for information regarding a $1.7 million charge recorded in 2017 for EICP severance payments to a former executive.

Significant Accounting Policies (Policies)	12 Months Ended
Significant Accounting Policies (Policies)	Dec. 31, 2017
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 Accounts receivable primarily result from the sales of motor fuels to customers and rental fees for retail sites. The majority of our accounts receivable relate to our motor fuel sales that can generally be described as high volume and low margin activities. Credit is extended to a customer based on an evaluation of the customer’s financial condition. In certain circumstances collateral may be required from the customer. Receivables are recorded at face value, without interest or discount. Receivables include amounts due from financial institutions for customer credit and debit card transactions. The provision for bad debts is generally based upon a specific analysis of aged accounts while also factoring in any new business conditions that might impact the historical analysis, such as market conditions and bankruptcies of particular customers. Bad debt provisions are included in selling, general and administrative expenses. We review all accounts receivable balances on at least a quarterly basis and provide an allowance for doubtful accounts based on historical experience and on a specific identification 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. Food and merchandise inventory is valued at the lower of average cost or net realizable value using the first-in, first-out method, net of a reserve for potentially obsolete or slow-moving inventory.
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.
Asset Acquisitions and Business Combinations	Asset Acquisitions and Business Combinations We early adopted ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, effective January 1, 2017. Under this guidance, we 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 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 these items 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. See Note 3 for additional information on our acquisitions.
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 five 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, wholesale fuel distribution rights and trademarks are amortized over 10 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 are amortized over the applicable lease term. Intangible assets with definite 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 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. We early adopted ASU 2017-04, Intangibles–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, effective January 1, 2017. 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.
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 21 for additional information.
Revenue Recognition	Revenue Recognition Revenues from the delivery of motor fuel are recorded upon 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. 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.
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 account for leases in accordance with ASC 840–Leases. We lease certain retail sites from third parties under long-term arrangements with various expiration dates. U.S. GAAP requires leases be evaluated and classified as either operating or capital 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 can be reasonably assured and failure to exercise such options would result in an economic penalty. Minimum lease payments are expensed on a straight-line basis over the term of the lease including renewal periods that are reasonably assured at the inception of the lease. In addition to minimum lease payments, certain leases require additional contingent payments based on sales volume or future inflation. 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 or the lease agreement has a repurchase feature, the sale-leaseback arrangements are accounted for as financing transactions.
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 and subordinated 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 (including common and subordinated unitholders) is computed by dividing the limited partners’ interest in net income, after deducting any incentive distributions, by the weighted-average number of outstanding common and subordinated units. As discussed in Note 17, all subordinated units converted to common units in the first quarter of 2016.
New Accounting Pronouncements	New Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09–Revenue from Contracts with Customers (Topic 606), which results in comprehensive new revenue accounting guidance, requires enhanced disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized, and develops a common revenue standard under U.S. GAAP and International Financial Reporting Standards. Specifically, 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 was effective January 1, 2018 and we applied the modified retrospective method of adoption. We have completed our assessment and have not identified any material impact on the financial statements, although it will affect disclosures. This guidance applies to over 90% of our revenues as the only primary revenue stream outside the scope of this guidance is rental income. In February 2016, the FASB issued ASU 2016-02–Leases (Topic 842). This standard modifies existing guidance for reporting organizations that enter into leases to increase transparency by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 is effective for fiscal years and interim periods within those years beginning after December 15, 2018, and requires a modified retrospective approach to adoption. Early adoption is permitted. Management continues to evaluate the impact of this new guidance, but the adoption will have a material impact on our balance sheet as we will be required to recognize right-of-use assets and lease liabilities for operating leases. We will not adopt this guidance early. We intend to apply each of the practical expedients in adopting this new guidance. In October 2016, the FASB issued ASU 2016-16–Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. This standard requires companies to account for income tax effects of intercompany transactions other than inventory in the period in which the transfer occurs rather than when the assets are transferred outside of the consolidated entity. We have chosen to early adopt the standard effective January 1, 2017, which had no impact as of the date of adoption but could apply to future intra-entity transactions and require us to recognize the income tax effects of those transactions in the period in which the transfer occurs. In January 2017, the FASB issued ASU 2017-01–Business Combinations (Topic 805): Clarifying the Definition of a Business. This standard clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. We early adopted this standard effective January 1, 2017. Although there was no impact upon adoption, among other things, this guidance results in the capitalization rather than expensing of acquisition costs in transactions that are accounted for as asset acquisitions rather than business combinations under the new definition of a business. In January 2017, the FASB issued ASU 2017-04–Intangibles–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This standard removes Step 2 of the goodwill impairment test. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Management early adopted this guidance effective January 1, 2017, which had no impact upon adoption but could result in a change in the measurement of an impairment loss if an impairment was required to be recorded in the future. Certain other new financial accounting pronouncements have become effective for our financial statements and the adoption of these pronouncements will not affect our financial position or results of operations, nor will they require any additional disclosures.
Concentration Risk	Concentration Risk For 2017, 2016 and 2015, we distributed approximately 13%, 16% and 17% of our total wholesale distribution volume to Dunne Manning Stores LLC, an entity associated with the family of a member of the Board (DMS) and DMS accounted for approximately 22%, 26% and 36% of our rental income, respectively. For 2017, 2016 and 2015, we distributed 8%, 8% and 7% of our total wholesale distribution volume to CST retail sites that are not supplied by CST Fuel Supply and received 20%, 21% and 17% of our rental income from CST, respectively. For more information regarding transactions with DMS and its affiliates and CST, see Note 12. In 2017, our wholesale business purchased approximately 28%, 27% and 16% of its motor fuel from ExxonMobil, BP and Motiva, respectively. In 2016, our wholesale business purchased approximately 30%, 25% and 24% of its motor fuel from ExxonMobil, BP and Motiva, respectively. In 2015, our wholesale business purchased approximately 30%, 26% and 26% of its motor fuel from ExxonMobil, BP and Motiva, respectively. No other fuel suppliers accounted for 10% or more of our motor fuel purchases during 2017, 2016 or 2015. Valero supplied substantially all of the motor fuel purchased by CST Fuel Supply during all periods presented. CST Fuel Supply purchased approximately 1.7 billion, 1.8 billion and 1.9 billion gallons of motor fuel from Valero for 2017, 2016 and 2015, respectively.

- Definition

The increases or decreases in lease payments that result from changes occurring after the inception of the lease in the factors (other than the passage of time) on which lease payments are based, except that any escalation of minimum lease payments relating to increases in construction or acquisition cost of the leased property or for increases in some measure of cost or value during the construction or preconstruction period, are excluded from contingent rentals. Contingent rentals also may include amounts for which the triggering events have not yet occurred or the specified targets for which have not yet been achieved (such as sales based percentage rent), but which events are considered probable of occurring or which specified targets are considered probable of being achieved.
