Organization and Basis of Presentation
Organization and Basis of Presentation	Note 1. Organization and Basis of Presentation Organization Global Partners LP (the “Partnership”) is a master limited partnership formed in March 2005. The Partnership owns, controls or has access to one of the largest terminal networks of refined petroleum products and renewable fuels in Massachusetts, Maine, Connecticut, Vermont, New Hampshire, Rhode Island, New York, New Jersey and Pennsylvania (collectively, the “Northeast”). The Partnership is one of the region’s largest independent owners, suppliers and operators of gasoline stations and convenience stores. As of December 31, 2019, the Partnership had a portfolio of 1,551 owned, leased and/or supplied gasoline stations, including 289 directly operated convenience stores, primarily in the Northeast. The Partnership is also one of the largest distributors of gasoline, distillates, residual oil and renewable fuels to wholesalers, retailers and commercial customers in the New England states and New York. The Partnership engages in the purchasing, selling, gathering, blending, storing and logistics of transporting petroleum and related products, including gasoline and gasoline blendstocks (such as ethanol), distillates (such as home heating oil, diesel and kerosene), residual oil, renewable fuels, crude oil and propane and in the transportation of petroleum products and renewable fuels by rail from the mid‑continent region of the United States and Canada. Global GP LLC, the Partnership’s general partner (the “General Partner”), manages the Partnership’s operations and activities and employs its officers and substantially all of its personnel, except for most of its gasoline station and convenience store employees who are employed by Global Montello Group Corp. (“GMG”), a wholly owned subsidiary of the Partnership. The General Partner, which holds a 0.67% general partner interest in the Partnership, is owned by affiliates of the Slifka family. As of December 31, 2019, affiliates of the General Partner, including its directors and executive officers and their affiliates, owned 7,402,198 common units, representing a 21.8% limited partner interest. 2019 and Recent Events 2027 Notes Offering and 2022 Notes Tender Offer and Redemption — On July 31, 2019, the Partnership and GLP Finance Corp. (the “Issuers”) issued $400.0 million aggregate principal amount of 7.00% senior notes due 2027 (the “2027 Notes”) to several initial purchasers (the “2027 Notes Initial Purchasers”) in a private placement exempt from the registration requirements under the Securities Act of 1933, as amended (the “Securities Act”). The Partnership used the net proceeds from the offering to fund the repurchase of its 6.25% senior notes due 2022 (the “2022 Notes”) in a tender offer and to repay a portion of the borrowings outstanding under its credit agreement. The redemption of the 2022 Notes occurred on August 30, 2019. See Note 8, “Debt and Financing Obligations—Senior Notes” for additional information on the 2027 Notes. On February 18, 2020, the Partnership completed an exchange offer whereby holders of the 2027 Notes exchanged all of the 2027 Notes for an equivalent amount of senior notes registered under the Securities Act. The exchange notes are substantially identical to the 2027 Notes, except that the exchange notes are not subject to the restrictions on transfers or to any increase in annual interest rates for failure to comply with the 2027 Notes Registration Rights Agreement (defined below). Amended Credit Agreement — On April 19, 2019, the Partnership and certain of its subsidiaries entered into the third amendment to third amended and restated credit agreement which, among other things, extended the maturity date from April 30, 2020 to April 29, 2022 and reduced by 0.25% the applicable rate under the existing revolving credit facility for borrowings of base rate loans, Eurocurrency rate loans and cost of funds rate loans and for issuances of letters of credit. See Note 8 for additional information on the credit agreement.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Consolidation and Presentation On July 24, 2018, the Partnership acquired the assets of company-operated gasoline stations and convenience stores from New Hampshire-based Cheshire Oil Company, LLC (“Cheshire”). On July 17, 2018, the Partnership acquired retail fuel and convenience store assets from Vermont-based Champlain Oil Company, Inc. (“Champlain”). On October 18, 2017, the Partnership acquired retail gasoline and convenience store assets from Honey Farms, Inc. (“Honey Farms”). The financial results of Cheshire, Champlain and Honey Farms since the respective acquisition date are included in the accompanying consolidated statements of operations. See Note 20, “Business Combinations,” for additional information on the Partnership’s acquisitions. The accompanying consolidated financial statements as of December 31, 2019 and 2018 and for the years ended December 31, 2019, 2018 and 2017 reflect the accounts of the Partnership. Upon consolidation, all intercompany balances and transactions have been eliminated. Noncontrolling Interest These financial statements reflect the application of Accounting Standards Codification (“ASC”) Topic 810, “Consolidations” (“ASC 810”) which establishes accounting and reporting standards that require: (i) the ownership interest in subsidiaries held by parties other than the parent to be clearly identified and presented in the consolidated balance sheet within shareholder’s equity, but separate from the parent’s equity, (ii) the amount of consolidated net income attributable to the parent and the noncontrolling interest to be clearly identified and presented on the face of the consolidated statements of operations, and (iii) changes in a parent’s ownership interest while the parent retains its controlling financial interest in its subsidiary to be accounted for consistently. The Partnership acquired a 60% interest in Basin Transload LLC (“Basin Transload”) on February 1, 2013. After evaluating ASC 810, the Partnership concluded it is appropriate to consolidate the balance sheet and statements of operations of Basin Transload based on an evaluation of the outstanding voting interests. Amounts pertaining to the noncontrolling ownership interest held by third parties in the financial position and operating results of the Partnership are reported as a noncontrolling interest in the accompanying consolidated balance sheets and statements of operations. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates under different assumptions or conditions. Among the estimates made by management are (i) estimated fair value of assets and liabilities acquired in a business combination and identification of associated goodwill and intangible assets, (ii) fair value of derivative instruments, (iii) accruals and contingent liabilities, (iv) allowance for doubtful accounts, (v) assumptions used to evaluate goodwill, property and equipment and intangibles for impairment, (vi) environmental and asset retirement obligation provisions, (vii) cost of sales accrual, and (viii) weighted average discount rate used in lease accounting. Although the Partnership believes these estimates are reasonable, actual results could differ from these estimates. Cash and Cash Equivalents The Partnership considers highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. The carrying value of cash and cash equivalents, including broker margin accounts, approximates fair value. Accounts Receivable The Partnership’s accounts receivable primarily results from sales of refined petroleum products, gasoline blendstocks, renewable fuels, crude oil and propane to its customers. The majority of the Partnership’s accounts receivable relates to its petroleum marketing activities that can generally be described as high volume and low margin activities. The Partnership makes a determination of the amount, if any, of a line of credit it may extend to a customer based on the form and amount of financial performance assurances the Partnership requires. Such financial assurances are commonly provided to the Partnership in the form of standby letters of credit, personal guarantees or corporate guarantees. The Partnership reviews all accounts receivable balances on a monthly basis and records a reserve for estimated amounts it expects will not be fully recovered. At December 31, 2019 and 2018, substantially all of the Partnership’s accounts receivable were classified as current assets and there were no non-standard payment terms. Inventories The Partnership hedges substantially all of its petroleum and ethanol inventory using a variety of instruments, primarily exchange-traded futures contracts. These futures contracts are entered into when inventory is purchased and are either designated as fair value hedges against the inventory on a specific barrel basis for inventories qualifying for fair value hedge accounting or not designated and maintained as economic hedges against certain inventory of the Partnership on a specific barrel basis. Changes in fair value of these futures contracts, as well as the offsetting change in fair value on the hedged inventory, are recognized in earnings as an increase or decrease in cost of sales. All hedged inventory designated in a fair value hedge relationship is valued using the lower of cost, as determined by specific identification, or net realizable value, as determined at the product level. All petroleum and ethanol inventory not designated in a fair value hedging relationship is carried at the lower of historical cost, on a first-in, first-out basis, or net realizable value. Renewable Identification Numbers (“RINs”) inventory is carried at the lower of historical cost, on a first-in, first-out basis, or net realizable value. Convenience store inventory is carried at the lower of historical cost, based on a weighted average cost method, or net realizable value. Inventories consisted of the following at December 31 (in thousands): 2019 2018 Distillates: home heating oil, diesel and kerosene $ 222,202 $ 173,403 Gasoline 120,958 93,534 Gasoline blendstocks 39,702 52,195 Crude oil 16,018 21,325 Residual oil 26,521 21,054 Propane and other 1,356 1,447 Renewable identification numbers (RINs) 1,329 1,034 Convenience store inventory 22,396 22,450 Total $ 450,482 $ 386,442 In addition to its own inventory, the Partnership has exchange agreements for petroleum products and ethanol with unrelated third‑party suppliers, whereby it may draw inventory from these other suppliers (see Revenue Recognition ) and suppliers may draw inventory from the Partnership. Positive exchange balances are accounted for as accounts receivable and amounted to $9.2 million and $3.8 million at December 31, 2019 and 2018, respectively. Negative exchange balances are accounted for as accounts payable and amounted to $17.6 million and $14.9 million at December 31, 2019 and 2018, respectively. Exchange transactions are valued using current carrying costs. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Minor expenditures for routine maintenance, repairs and renewals are charged to expense as incurred, and major improvements that extend the useful lives of the related assets are capitalized. Depreciation related to the Partnership’s terminal assets and gasoline stations is charged to cost of sales and all other depreciation is charged to selling, general and administrative expenses. Depreciation is charged over the estimated useful lives of the applicable assets using straight‑line methods, and accelerated methods are used for income tax purposes. When applicable and based on policy, which considers the construction period and project cost, the Partnership capitalizes interest on qualified long‑term projects and depreciates it over the life of the related asset. The estimated useful lives are as follows: Gasoline station buildings, improvements and storage tanks 15-25 years Buildings, docks, terminal facilities and improvements 5-25 years Gasoline station equipment 7 years Fixtures, equipment and capitalized internal use software 3-7 years The Partnership capitalizes certain costs, including internal payroll and external direct project costs incurred in connection with developing or obtaining software designated for internal use. These costs are included in property and equipment and are amortized over the estimated useful lives of the related software. Intangibles Intangibles are carried at cost less accumulated amortization. For assets with determinable useful lives, amortization is computed over the estimated economic useful lives of the respective intangible assets, ranging from 3 to 20 years. Goodwill and Long-Lived Asset Impairment Goodwill Goodwill represents the future economic benefits arising from assets acquired in a business combination that are not individually identified and separately recognized. The Partnership has concluded that its operating segments are also its reporting units. Goodwill is tested for impairment annually as of October 1 or when events or changes in circumstances indicate that the carrying amount of goodwill may not be recoverable. Derecognized goodwill associated with the Partnership’s disposition activities of Gasoline Distribution and Station Operation (“GDSO”) sites is included in the carrying value of assets sold in determining the gain or loss on disposal, to the extent the disposition of assets qualifies as a disposition of a business under ASC 805. The GDSO reporting unit’s goodwill that was derecognized related to the disposition of sites that met the definition of a business was $2.9 million, $3.9 million and $4.0 million for the years ended December 31, 2019, 2018 and 2017, respectively (see Note 7). All of the Partnership’s goodwill is allocated to the GDSO segment. During 2019, 2018 and 2017, the Partnership completed a quantitative assessment for the GDSO reporting unit. Factors included in the assessment included both macro‑economic conditions and industry specific conditions, and the fair value of the GDSO reporting unit was estimated using a weighted average of a discounted cash flow approach and a market comparables approach. Based on the Partnership’s assessment, no impairment was identified. Evaluation of Long-Lived Asset Impairment Accounting and reporting guidance for long‑lived assets requires that a long‑lived asset (group) be reviewed for impairment when events or changes in circumstances indicate that the carrying amount might not be recoverable. Accordingly, the Partnership evaluates long-lived assets for impairment whenever indicators of impairment are identified. If indicators of impairment are present, the Partnership assesses impairment by comparing the undiscounted projected future cash flows from the long‑lived assets to their carrying value. If the undiscounted cash flows are less than the carrying value, the long‑lived assets will be reduced to their fair value. The Partnership recognized an impairment charge of $2.0 million, $0.4 million and $0.8 million for the years ended December 31, 2019, 2018 and 2017, respectively, relating to long-lived assets at certain gasoline stations and convenience stores. These assets are allocated to the GDSO segment, and the respective impairment is included in goodwill and long-lived asset impairment in the accompanying consolidated statements of operations for the years ended December 31, 2019, 2018 and 2017. Environmental and Other Liabilities The Partnership accrues for all direct costs associated with the estimated resolution of contingencies at the earliest date at which it is deemed probable that a liability has been incurred and the amount of such liability can be reasonably estimated. Costs accrued are estimated based upon an analysis of potential results, assuming a combination of litigation and settlement strategies and outcomes. Estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study. Loss accruals are adjusted as further information becomes available or circumstances change. Costs of future expenditures for environmental remediation obligations are not discounted to their present value. Recoveries of environmental remediation costs from other parties are recognized when related contingencies are resolved, generally upon cash receipt. The Partnership is subject to other contingencies, including legal proceedings and claims arising out of its businesses that cover a wide range of matters, including environmental matters and contract and employment claims. Environmental and other legal proceedings may also include matters with respect to businesses previously owned. Further, due to the lack of adequate information and the potential impact of present regulations and any future regulations, there are certain circumstances in which no range of potential exposure may be reasonably estimated. See Notes 14 and 23. . Asset Retirement Obligations The Partnership is required to account for the legal obligations associated with the long‑lived assets that result from the acquisition, construction, development or operation of long‑lived assets. Such asset retirement obligations specifically pertain to the treatment of underground gasoline storage tanks (“USTs”) that exist in those states which statutorily require removal of the USTs at a certain point in time. Specifically, the Partnership’s retirement obligations consist of the estimated costs of removal and disposals of USTs. The liability for an asset retirement obligation is recognized on a discounted basis in the year in which it is incurred, and the discount period applied is based on statutory requirements for UST removal or policy. The associated asset retirement costs are capitalized as part of the carrying cost of the asset. The Partnership had approximately $8.0 million and $8.8 million in total asset retirement obligations at December 31, 2019 and 2018, respectively, which are included in other long‑term liabilities in the accompanying consolidated balance sheets. Leases The Partnership has gasoline station and convenience store leases, primarily of land and buildings. The Partnership has terminal and dedicated storage facility lease arrangements with various petroleum terminals and third parties, of which certain arrangements have minimum usage requirements. The Partnership leases barges through various time charter lease arrangements and railcars through various lease arrangements. The Partnership also has leases for office space, computer and convenience store equipment and automobiles. The Partnership’s lease arrangements have various expiration dates with options to extend. The Partnership is also the lessor party to various lease arrangements with various expiration dates, including the leasing of gasoline stations and certain equipment to third-party station operators and cobranding lease agreements for certain space within the Partnership’s gasoline stations and convenience stores. In addition, the Partnership is party to three master unitary lease agreements in connection with (i) the June 2015 acquisition of retail gasoline stations from Capitol Petroleum Group (“Capitol”) related to properties previously sold by Capitol within two sale-leaseback transactions; and (ii) the June 2016 sale of real property assets at 30 gasoline stations and convenience stores that did not meet the criteria for sale accounting. These transactions continue to be accounted for as financing obligations (see Note 8) upon transition to ASC 842, “Leases,” which the Partnership adopted on January 1, 2019. Accounting and reporting guidance for leases requires that leases be evaluated and classified as either operating or finance leases by the lessee and as either operating, sales-type or direct financing leases by the lessor. The Partnership’s operating leases are included in right-of-use (“ROU”) assets, lease liability-current portion and long-term lease liability-less current portion in the accompanying consolidated balance sheets. ROU assets represent the Partnership’s right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Partnership’s variable lease payments consist of payments that depend on an index or rate (such as the Consumer Price Index) as well as those payments that depend on the Partnership’s performance or use of the underlying asset related to the lease. Variable lease payments are excluded from the ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. As most of the Partnership’s leases do not provide an implicit rate in determining the net present value of lease payments, the Partnership uses its incremental borrowing rate based on the information available at the lease commencement date. ROU assets also include any lease payments made and exclude lease incentives. Many of the Partnership’s lessee agreements include options to extend the lease, which are not included in the minimum lease terms unless they are reasonably certain to be exercised. Rental expense for lease payments related to operating leases is recognized on a straight-line basis over the lease term. Rental income for lease payments received related to operating leases is recognized on a straight-line basis over the lease term. The Partnership has elected the package of practical expedients permitted under the transition guidance within the new standard which, among other things, allows the Partnership to carry forward the historical accounting relating to lease identification and classification for existing leases upon adoption. Leases with an initial term of 12 months or less are not recorded on the balance sheet as the Partnership recognizes lease expense for these leases on a straight-line basis over the lease term. The Partnership’s leases have contracted terms as follows: Gasoline station and convenience store leases 1-20 years Terminal lease arrangements 1-5 years Dedicated storage facility leases 1-5 years Barge and railcar equipment leases 1-10 years Office space leases 1-12 years Computer equipment, convenience store equipment and automobile leases 1-5 years The above table excludes the Partnership’s West Coast facility land lease arrangement which contract term is subject to expiration through July 2066. Some of the above leases include options to extend the leases for up to an additional 30 years. The Partnership does not include renewal options in its lease terms for calculating the lease liability unless the Partnership is reasonably certain the renewal options are to be exercised. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Lease Exit Termination Gain In December 2016, the Partnership voluntarily terminated early a sublease with a counterparty for 1,610 railcars that were underutilized due to unfavorable market conditions in the crude oil by rail market. Separately, the Partnership entered into a fleet management services agreement (effective January 1, 2017) (the “Services Agreement”) with the counterparty, pursuant to which the Partnership would provide railcar storage, freight, insurance and other services on behalf of the counterparty. During each of 2019 and 2018, the Partnership was released from certain of its obligations under the Services Agreement, which resulted in a reduction of the remaining accrued incremental costs of $0.5 million and $3.5 million for the years ended December 31, 2019 and 2018, respectively, which benefit is included in lease exit and termination gain in the accompanying statements of operations. The remaining accrued incremental costs were $1.3 million at December 31, 2019. Revenue Recognition The Partnership’s sales relate primarily to the sale of refined petroleum products, gasoline blendstocks, renewable fuels, crude oil and propane and are recognized along with the related receivable upon delivery, net of applicable provisions for discounts and allowances. The Partnership may also provide for shipping costs at the time of sale, which are included in cost of sales. Contracts with customers typically contain pricing provisions that are tied to a market index, with certain adjustments based on quality and freight due to location differences and prevailing supply and demand conditions, as well as other factors. As a result, the price of the products fluctuates to remain competitive with other available product supplies. The revenue associated with such arrangements is recognized upon delivery. In addition, the Partnership generates revenue from its logistics activities when it stores, transloads and ships products owned by others. Revenue from logistics services is recognized as services are provided. Logistics agreements may require counterparties to throughput a minimum volume over an agreed-upon period and may include make-up rights if the minimum volume is not met. The Partnership recognizes revenue associated with make-up rights at the earlier of when the make-up volume is shipped, the make-up right expires or when it is determined that the likelihood that the shipper will utilize the make-up right is remote. The Partnership also recognizes convenience store sales of gasoline, grocery and other merchandise and sundries at the time of the sale to the customer. Gasoline station rental income is recognized on a straight‑line basis over the term of the lease. Product revenue is not recognized on exchange agreements, which are entered into primarily to acquire various refined petroleum products, gasoline blendstocks, renewable fuels and crude oil of a desired quality or to reduce transportation costs by taking delivery of products closer to the Partnership’s end markets. The Partnership recognizes net exchange differentials due from exchange partners in sales upon delivery of product to an exchange partner. The Partnership recognizes net exchange differentials due to exchange partners in cost of sales upon receipt of product from an exchange partner. The amounts recorded for bad debts are 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. Trustee Taxes The Partnership collects trustee taxes, which consist of various pass through taxes collected on behalf of taxing authorities, and remits such taxes directly to those taxing authorities. Examples of trustee taxes include, among other things, motor fuel excise tax and sales and use tax. As such, it is the Partnership’s policy to exclude trustee taxes from revenues and cost of sales and account for them as current liabilities. See Note 12 for additional information. The Partnership may be subject to audits of its state and federal tax returns prepared for trustee taxes. Historically, any tax adjustments from such audits have been deemed immaterial by the Partnership and have been included in cost of sales. In November of 2017, the Partnership received an assessment from a state taxing authority in connection with its audit of the Partnership’s fuel and sales tax returns for the periods from December 2008 through August 2013 (the “Audit”). In February of 2018, the Partnership agreed to administratively close the Audit, and, as a result, recognized a loss on trustee taxes of $16.2 million during the fourth quarter of 2017, which is included in (gain) loss on trustee taxes in the accompanying consolidated statements of operations for the year ended December 31, 2017. The loss on trustee taxes consists of both tax and interest, with no penalties being assessed. Although the Audit has been administratively closed, the Partnership has the right to seek recovery of the payment of the trustee tax. While the Partnership believes it has meritorious arguments and defenses to recover a majority of the tax and interest assessed, the Partnership cannot be certain of such outcome. Volumetric Ethanol Excise Tax Credit— In the first quarter of 2018, the Partnership recognized a one-time income item of approximately $52.6 million as a result of the extinguishment of a contingent liability related to the Volumetric Ethanol Excise Tax Credit, which tax credit program expired in 2011. Based upon the significant passage of time from that 2011 expiration date, including underlying statutes of limitation, as of January 31, 2018 the Partnership determined that the liability was no longer required. The liability had historically been included in trustee taxes in the accompanying consolidated balance sheets. The recognition of this one-time income item, which is included in (gain) loss on trustee taxes in the accompanying consolidated statements of operations for the year ended December 31, 2018, did not impact cash flows from operations for the year ended December 31, 2018. Income Taxes Section 7704 of the Internal Revenue Code provides that publicly‑traded partnerships are, as a general rule, taxed as corporations. However, an exception, referred to as the “Qualifying Income Exception,” exists under Section 7704(c) with respect to publicly‑traded partnerships of which 90% or more of the gross income for every taxable year consists of “qualifying income.” Qualifying income includes income and gains derived from the transportation, storage and marketing of refined petroleum products, gasoline blendstocks, crude oil and ethanol to resellers and refiners. Other types of qualifying income include interest (other than from a financial business), dividends, gains from the sale of real property and gains from the sale or other disposition of capital assets held for the production of income that otherwise constitutes qualifying income. Substantially all of the Partnership’s income is “qualifying income” for federal income tax purposes and, therefore, is not subject to federal income taxes at the partnership level. Accordingly, no provision has been made for income taxes on the qualifying income in the Partnership’s financial statements. Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under the Partnership’s agreement of limited partnership. Individual unitholders have different investment basis depending upon the timing and price at which they acquired their common units. Further, each unitholder’s tax accounting, which is partially dependent upon the unitholder’s tax position, differs from the accounting followed in the Partnership’s consolidated financial statements. Accordingly, the aggregate difference in the basis of the Partnership’s net assets for financial and tax reporting purposes cannot be readily determined because information regarding each unitholder’s tax attributes in the Partnership is not available to the Partnership. One of the Partnership’s wholly owned subsidiaries, GMG, is a taxable entity for federal and state income tax purposes. Current and deferred income taxes are recognized on the separate earnings of GMG. The after‑tax earnings of GMG are included in the earnings of the Partnership. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes for GMG. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Partnership calculates its current and deferred tax provision based on estimates and assumptions that could differ from actual results reflected in income tax returns filed in subsequent years. Adjustments based on filed returns are recorded when identified. See Note 13. Concentration of Risk Financial instruments that potentially subject the Partnership to concentration of credit risk consist primarily of cash, cash equivalents, accounts receivable, firm commitments and, under certain circumstances, futures contracts, forward fixed price contracts, options and swap agreements which may be used to hedge commodity and interest rate risks. The Partnership provides credit in the normal course of its business. The Partnership performs ongoing credit evaluations of its customers and provides for credit losses based on specific information and historical trends. Credit risk on trade receivables is minimized as a result of the Partnership’s large customer base. Losses have historically been within management’s expectations. See Note 9 for a discussion regarding risk of credit loss related to futures contracts, forward fixed price contracts, options and swap agreements. The Partnership’s wholesale and commercial customers of refined petroleum products, gasoline blendstocks, renewable fuels, crude oil and propane are located primarily in the Northeast. The Partnership’s retail gasoline stations and directly operated convenience stores are also located primarily in the Northeast. Due to the nature of the Partnership’s businesses and its reliance, in part, on consumer travel and spending patterns, the Partnership may experience more demand for gasoline during the late spring and summer months than during the fall and winter. Travel and recreational activities are typically higher in these months in the geographic areas in which the Partnership operates, increasing the demand for gasoline. Therefore, the Partnership’s volumes in gasoline are typically higher in the second and third quarters of the calendar year. As demand for some of the Partnership’s refined petroleum products, specifically home heating oil and residual oil for space heating purposes, is generally greater during the winter months, heating oil and residual oil volumes are generally higher during the first and fourth quarters of the calendar year. These factors may result in fluctuations in the Partnership’s quarterly operating results. The following table presents the Partnership’s product sales and other revenues as a percentage of the consolidated sales for the years ended December 31: 2019 2018 2017 Gasoline sales: gasoline and gasoline blendstocks (such as ethanol) 75 % 74 % 65 % Distillates (home heating oil, diesel and kerosene), residual oil and propane sales 21 % 22 % 26 % Crude oil sales and crude oil logistics revenue 1 % 1 % 5 % Convenience store sales, rental income and sundries 3 % 3 % 4 % Total 100 % 100 % 100 % The following table presents the Partnership’s product margin (product sales minus product costs) by segment as a percentage of the consolidated product margin for the years ended December 31: 2019 2018 2017 Wholesale segment 16 % 19 % 23 % Gasoline Distribution and Station Operations segment 80 % 78 % 74 % Commercial segment 4 % 3 % 3 % Total 100 % 100 % 100 % See Note 21, “Segment Reporting,” for additional information on the Partnership’s operating segments. The Partnership is dependent on a number of suppliers of fuel‑related products, both domestically and internationally. The Partnership is dependent on the suppliers being able to source product on a timely basis and at favorable pricing terms. The loss of certain principal suppliers or a sign

Leases [Abstract]
Leases	Note 3. Leases On January 1, 2019, the Partnership adopted ASC 842 using the prospective transition approach, which applies the provisions of the new guidance at the effective date without adjusting the comparative periods presented. The adoption of the lease standard did not result in a cumulative-effect adjustment to opening equity. Results for reporting periods beginning after January 1, 2019 are presented under ASC 842 while prior period amounts are not adjusted and continue to be reported in accordance with the Partnership’s historic accounting under ASC 840, “Leases,” (“ASC 840”). The adoption of ASC 842 resulted in the recognition of ROU assets and lease liabilities of approximately $330.8 million and $340.8 million, respectively, as of January 1, 2019. The difference between ROU asset and lease liabilities of $10.0 million is primarily associated with amounts previously recognized on the Partnership’s consolidated balance sheet under ASC 840 and is recognized net within ROU assets under ASC 842. The standard did not materially impact the Partnership’s consolidated statement of operations or its consolidated statement of cash flows for the year ended December 31, 2019. See Note 2 for the Partnership’s lease policy and below for the required disclosures under ASC 842. The following table presents supplemental balance sheet information related to leases at December 31, 2019 (in thousands): Assets: Balance Sheet Location ROU assets - operating Right-of-use assets, net $ 296,746 Liabilities: Current lease liability - operating Lease liability - current portion $ 68,160 Noncurrent lease liability - operating Lease liability - less current portion 239,349 Total lease liability $ 307,509 Lessee Lease Arrangements The following table presents the components of lease cost for the year ended December 31, 2019 (in thousands): Statement of operations location: Cost of sales (a) $ 57,369 Selling, general and administrative expenses 3,094 Operating expenses (b) 50,904 Total lease cost $ 111,367 (a) Includes short-term lease costs of $2.5 million. (b) Includes variable lease cost of $6.7 million and short-term leases costs which were immaterial. Operating lease costs included in cost of sales are primarily associated with leases of barges and railcars and dedicated storage facility lease arrangements. Operating lease costs included in operating expenses are primarily associated with the leases of gasoline station and convenience stores and terminal lease arrangements where the Partnership is responsible for operating the terminal facility. Operating lease costs included in selling, general and administrative expenses are primarily associated with the leases of office space, computers and automobiles. The future minimum lease payments to be paid under operating leases in effect and included in the calculation of lease liabilities at December 31, 2019 were as follows (in thousands): 2020 $ 86,156 2021 78,729 2022 54,672 2023 43,501 2024 31,983 Thereafter 85,788 Total lease payments 380,829 Less imputed interest 73,320 Total lease liabilities $ 307,509 Current portion $ 68,160 Long-term portion 239,349 Total lease liabilities $ 307,509 The future minimum lease payments include $19.7 million related to options to extend lease terms that are reasonably certain of being exercised and exclude $2.3 million in lease payments that were not fixed at lease commencement or lease modification and $1.3 million related to minimum lease payments for leases that are less than one year. Lessor Lease Arrangements The following table presents the components of lease revenue for the year ended December 31, 2019 (in thousands): Statement of operations location: Sales (a)(b) $ 74,184 (a) Lease revenue includes sub-lessor rental income from leased properties of $38.3 million for the year ended December 31, 2019, where the Partnership is the lessee of the property. (b) Includes variable lease revenue of $6.4 million for the year ended December 31, 2019 and short-term lease revenue which was immaterial for the year ended December 31, 2019. The future minimum lease payments to be received under operating leases in effect at December 31, 2019 were as follows (in thousands): 2020 $ 63,012 2021 35,984 2022 19,787 2023 6,547 2024 4,445 Thereafter 11,114 Total $ 140,889 Supplemental Information Related to Lease Arrangements The following table presents supplemental information related to leases as of and for the year ended December 31, 2019 (in thousands): Cash paid for amounts included in the measurement of lease liabilities $ 105,366 Right-of-use assets obtained in exchange for new lease liabilities $ 54,313 Weighted average remaining non-cancellable lease term 6.0 years Weighted average discount rate as of December 31, 2019

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Note 4. Revenue from Contracts with Customers On January 1, 2018, the Partnership adopted ASC 606, “Revenue from Contracts with Customers” (“ASC 606”) using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning January 1, 2018 are presented under ASC 606 while prior period amounts are not adjusted and continue to be reported in accordance with the Partnership’s historic accounting under ASC 605, “Revenue Recognition,” (“ASC 605”). See Note 2 for the Partnership’s revenue recognition policy and below for the required disclosures under ASC 606. Disaggregation of Revenue The following table provides the disaggregation of revenue from contracts with customers and other sales by segment for the periods presented (in thousands): Year Ended December 31, 2019 Revenue from contracts with customers: Wholesale GDSO Commercial Total Refined petroleum products, renewable fuels, crude oil and propane $ 1,681,426 $ 3,806,892 $ 794,082 $ 6,282,400 Station operations — 394,679 — 394,679 Total revenue from contracts with customers 1,681,426 4,201,571 794,082 6,677,079 Other sales: Revenue originating as physical forward contracts and exchanges 5,746,338 — 584,129 6,330,467 Revenue from leases 2,102 72,082 — 74,184 Total other sales 5,748,440 72,082 584,129 6,404,651 Total sales $ 7,429,866 $ 4,273,653 $ 1,378,211 $ 13,081,730 Year Ended December 31, 2018 Revenue from contracts with customers: Wholesale GDSO Commercial Total Refined petroleum products, renewable fuels, crude oil and propane $ 1,580,156 $ 4,081,498 $ 769,271 $ 6,430,925 Station operations — 355,656 — 355,656 Total revenue from contracts with customers 1,580,156 4,437,154 769,271 6,786,581 Other sales: Revenue originating as physical forward contracts and exchanges 5,308,613 — 503,832 5,812,445 Revenue from leases 2,021 71,555 — 73,576 Total other sales 5,310,634 71,555 503,832 5,886,021 Total sales $ 6,890,790 $ 4,508,709 $ 1,273,103 $ 12,672,602 Nature of Goods and Services Revenue from Contracts with Customers (ASC 606) : · Refined petroleum products, renewable fuels, crude oil and propane sales —Under the Partnership’s Wholesale, GDSO and Commercial segments, revenue is recognized at the point where control of the product is transferred to the customer and collectability is reasonably assured. · Station operations —Revenue from convenience store sales of grocery and other merchandise and sundries (such as car wash sales and lottery and ATM commissions) is recognized at the time of the sale to the customer. Other Revenue : · Revenue Originating as Physical Forward Contracts and Exchanges —The Partnership’s commodity contracts and derivative instrument activity include physical forward commodity sale contracts. The Partnership does not take the normal purchase and sale exemption available under ASC 815, “Derivatives and Hedging,” for any of its physical forward contracts. This income is recognized under ASC 815 and is included in sales at the contract value at the point where control of the product is transferred to the customer. Income from net exchange differentials included in sales is recognized under ASC 845, “Nonmonetary Transactions,” upon delivery of product to exchange partners. · Revenue from Leases —The Partnership has rental income from gasoline stations and cobranding arrangements and lease income from space leased to several unrelated third parties at several of the Partnership’s terminals. This income was recognized under ASC 842 for the year ended December 31, 2019 and under ASC 840, “Leases,” for the years ended December 31, 2018 and 2017. Transaction Price Allocated to Remaining Performance Obligations The Partnership has elected certain of the optional exemptions from the disclosure requirement for remaining performance obligations for specific situations in which an entity need not estimate variable consideration to recognize revenue. Accordingly, the Partnership applies the practical expedient in paragraph ASC 606-10-50-14 to its contracts with customers where revenue is tied to a market-index and does not disclose information about variable consideration from remaining performance obligations for which the Partnership recognizes revenue. The fixed component of estimated revenues expected to be recognized in the future related to performance obligations tied to a market index that are unsatisfied (or partially unsatisfied) at the end of the reporting period are not significant. Contract Balances A receivable, which is included in accounts receivable, net in the accompanying consolidated balance sheets, is recognized in the period the Partnership provides services when its right to consideration is unconditional. In contrast, a contract asset will be recognized when the Partnership has fulfilled a contract obligation but must perform other obligations before being entitled to payment. The nature of the receivables related to revenue from contracts with customers and other revenue, as well as contract assets, are the same, given they are related to the same customers and have the same risk profile and securitization. The Partnership had no significant contract liabilities at both December 31, 2019 and 2018. Payment terms on invoiced amounts are typically 2 to 30 days. A contract liability is recognized when the Partnership has an obligation to transfer goods or services to a customer for which the Partnership has received consideration (or the amount is due) from the customer.

Property and Equipment	Note 6. Property and Equipment Property and equipment consisted of the following at December 31 (in thousands): 2019 2018 Buildings and improvements $ 1,196,502 $ 1,126,645 Land 452,104 456,334 Fixtures and equipment 46,848 44,479 Idle plant assets 30,500 30,500 Construction in process 27,951 37,636 Capitalized internal use software 33,502 32,127 Total property and equipment 1,787,407 1,727,721 Less accumulated depreciation 682,544 595,089 Total $ 1,104,863 $ 1,132,632 Property and equipment includes assets held for sale of $4.6 million and $8.1 million at December 31, 2019 and 2018, respectively. At December 31, 2019, the Partnership had a $44.5 million remaining net book value of long-lived assets at its West Coast facility, including $30.5 million related to the Partnership’s ethanol plant acquired in 2013. In 2016, the Partnership shifted the facility from crude oil to ethanol transloading and began transloading ethanol. The Partnership would need to take certain measures to prepare the facility for ethanol production in order to place the plant into service and commence depreciation. Therefore, the $30.5 million related to the ethanol plant was included in property and equipment and classified as idle plant assets at December 31, 2019 and 2018. If the Partnership is unable to generate cash flows to support the recoverability of the plant and facility assets, this may become an indicator of potential impairment of the West Coast facility. The Partnership believes these assets are recoverable but continues to monitor the market for ethanol, the continued business development of this facility for ethanol or other product transloading, and the related impact this may have on the facility’s operating cash flows and whether this would constitute an impairment indicator. Construction in process in 2019 included $23.1 million in costs related to the Partnership’s gasoline stations and $4.8 million in costs related to the Partnership’s terminals. Construction in process in 2018 included $28.0 million in costs related to the Partnership’s gasoline stations and $9.6 million in costs related to the Partnership’s terminals. Depreciation Depreciation expense allocated to cost of sales was approximately $87.9 million, $86.9 million and $88.5 million for the years ended December 31, 2019, 2018 and 2017, respectively. Depreciation expense allocated to selling, general and administrative expenses was approximately $8.8 million, $9.0 million and $7.9 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Debt and Financing Obligations
Debt and Financing Obligations	Note 8. Debt and Financing Obligations Credit Agreement Certain subsidiaries of the Partnership, as borrowers, and the Partnership and certain of its subsidiaries, as guarantors, have a $1.3 billion senior secured credit facility (the “Credit Agreement”). The Credit Agreement matures on April 29, 2022. There are two facilities under the Credit Agreement: · a working capital revolving credit facility to be used for working capital purposes and letters of credit in the principal amount equal to the lesser of the Partnership’s borrowing base and $850.0 million; and · a $450.0 million revolving credit facility to be used for general corporate purposes. In addition, the Credit Agreement has an accordion feature whereby the Partnership may request on the same terms and conditions then applicable to the Credit Agreement, provided no Event of Default (as defined in the Credit Agreement) then exists, an increase to the working capital revolving credit facility, the revolving credit facility, or both, by up to another $300.0 million, in the aggregate, for a total credit facility of up to $1.6 billion. Any such request for an increase must be in a minimum amount of $25.0 million. The Partnership cannot provide assurance, however, that its lending group will agree to fund any request by the Partnership for additional amounts in excess of the total available commitments of $1.3 billion. In addition, the Credit Agreement includes a swing line pursuant to which Bank of America, N.A., as the swing line lender, may make swing line loans in U.S. dollars in an aggregate amount equal to the lesser of (a) $75.0 million and (b) the Aggregate WC Commitments (as defined in the Credit Agreement). Swing line loans will bear interest at the Base Rate (as defined in the Credit Agreement). The swing line is a sub-portion of the working capital revolving credit facility and is not an addition to the total available commitments of $1.3 billion. Availability under the working capital revolving credit facility is subject to a borrowing base which is redetermined from time to time and based on specific advance rates on eligible current assets. Under the Credit Agreement, borrowings under the working capital revolving credit facility cannot exceed the then current borrowing base. Availability under the borrowing base may be affected by events beyond the Partnership’s control, such as changes in petroleum product prices, collection cycles, counterparty performance, advance rates and limits and general economic conditions. These and other events could require the Partnership to seek waivers or amendments of covenants or alternative sources of financing or to reduce expenditures. The Partnership can provide no assurance that such waivers, amendments or alternative financing could be obtained or, if obtained, would be on terms acceptable to the Partnership. Borrowings under the working capital revolving credit facility bear interest at (1) the Eurocurrency rate plus 2.00% to 2.50%, (2) the cost of funds rate plus 2.00% to 2.50%, or (3) the base rate plus 1.00% to 1.50%, each depending on the Utilization Amount (as defined in the Credit Agreement). Borrowings under the revolving credit facility bear interest at (1) the Eurocurrency rate plus The average interest rates for the Credit Agreement were 4.3%, 4.0% and 3.7% for the years ended December 31, 2019, 2018 and 2017, respectively. The Credit Agreement provides for a letter of credit fee equal to the then applicable working capital rate or then applicable revolver rate (each such rate as defined in the Credit Agreement) per annum for each letter of credit issued. In addition, the Partnership incurs a commitment fee on the unused portion of each facility under the Credit Agreement, ranging from 0.35% to 0.50% per annum. The Partnership classifies a portion of its working capital revolving credit facility as a current liability and a portion as a long-term liability. The portion classified as a long-term liability represents the amounts expected to be outstanding during the entire year based on an analysis of historical daily borrowings under the working capital revolving credit facility, the seasonality of borrowings, forecasted future working capital requirements and forward product curves, and because the Partnership has a multi-year, long-term commitment from its bank group. Accordingly, at December 31, 2019, the Partnership estimated working capital revolving credit facility borrowings will equal or exceed $175.0 million over the next twelve months and, therefore, classified $148.9 million as the current portion at December 31, 2019, representing the amount the Partnership expects to pay down over the next twelve months. The long-term portion of the working capital revolving credit facility was $175.0 million and $150.0 million at December 31, 2019 and 2018, respectively, and the current portion was $148.9 million and $103.3 million at December 31, 2019 and 2018, respectively. The increase in total borrowings under the working capital revolving credit facility of $70.6 million from December 31, 2018 was primarily due to higher prices. As of December 31, 2019, the Partnership had total borrowings outstanding under the Credit Agreement of $516.6 million, including $192.7 million outstanding on the revolving credit facility. In addition, the Partnership had outstanding letters of credit of $123.2 million. Subject to borrowing base limitations, the total remaining availability for borrowings and letters of credit was $660.2 million and $770.7 million at December 31, 2019 and 2018, respectively. The Credit Agreement is secured by substantially all of the assets of the Partnership and the Partnership’s wholly-owned subsidiaries and is guaranteed by the Partnership and its subsidiaries, Bursaw Oil LLC, Global Partners Energy Canada ULC, Warex Terminals Corporation, Drake Petroleum Company, Inc., Puritan Oil Company, Inc. and Maryland Oil Company, Inc. The Credit Agreement imposes certain requirements on the borrowers including, for example, a prohibition against distributions if any potential default or Event of Default (as defined in the Credit Agreement) would occur as a result thereof, and certain limitations on the Partnership’s ability to grant liens, make certain loans or investments, incur additional indebtedness or guarantee other indebtedness, make any material change to the nature of the Partnership’s businesses or undergo a fundamental change, make any material dispositions, acquire another company, enter into a merger, consolidation, or sale-leaseback transaction or purchase of assets. The Credit Agreement also includes certain baskets, including: (i) a $25.0 million general secured indebtedness basket, (ii) a $25.0 million general investment basket, (iii) a $75.0 million secured indebtedness basket to permit the borrowers to enter into a Contango Facility (as defined in the Credit Agreement), (iv) a Sale/Leaseback Transaction (as defined in the Credit Agreement) basket of $100.0 million, and (v) a basket of $50.0 million in an aggregate amount for the purchase of common units of the Partnership, provided that no Event of Default exists or would occur immediately following such purchase(s). In addition, the Credit Agreement provides the ability for the borrowers to repay certain junior indebtedness, subject to a $100.0 million cap, so long as no Event of Default has occurred or will exist immediately after making such repayment. The Credit Agreement imposes financial covenants that require the Partnership to maintain certain minimum working capital amounts, a minimum combined interest coverage ratio, a maximum senior secured leverage ratio and a maximum total leverage ratio. The Partnership was in compliance with the foregoing covenants at December 31, 2019. The Credit Agreement also contains a representation whereby there can be no event or circumstance, either individually or in the aggregate, that has had or could reasonably be expected to have a Material Adverse Effect (as defined in the Credit Agreement). In addition, the Credit Agreement limits distributions by the Partnership to its unitholders to the amount of Available Cash (as defined in the Partnership’s partnership agreement). Deferred Financing Fees The Partnership incurs bank fees related to its Credit Agreement and other financing arrangements. These deferred financing fees are capitalized and amortized over the life of the Credit Agreement or other financing arrangements. In 2019, the Partnership capitalized additional financing fees of $13.5 million, consisting of $7.4 million in connection with the issuance of the 2027 Notes and $6.1 million in connection with the amendment to the Credit Agreement (discussed below). The Partnership had unamortized deferred financing fees of $18.0 million and $10.5 million at December 31, 2019 and 2018, respectively. Unamortized fees related to the Credit Agreement are included in other current assets and other long-term assets and amounted to $7.8 million and $5.5 million at December 31, 2019 and 2018, respectively. Unamortized fees related to the senior notes are presented as a direct deduction from the carrying amount of that debt liability and amounted to $9.5 million and $4.2 million at December 31, 2019 and 2018, respectively. Unamortized fees related to the Sale-Leaseback Transaction are presented as a direct deduction from the carrying amount of the financing obligation and amounted to $0.7 million and $0.8 million at December 31, 2019 and 2018, respectively. On April 19, 2019, the Partnership entered into the Third Amendment to Third Amended and Restated Credit Agreement which, among other things, extended the maturity date from April 30, 2020 to April 29, 2022 and reduced by 0.25% the applicable rate under the existing revolving credit facility for borrowings of base rate loans, Eurocurrency rate loans and cost of funds rate loans and for issuances of letters of credit. As a result, the Partnership incurred expenses of approximately $0.2 million associated with the write-off of a portion of the related deferred financing fees. These expenses are included in interest expense in the accompanying consolidated statement of operations for year ended December 31, 2019. On April 25, 2017, the Partnership entered into a Third Amended and Restated Credit Agreement, a facility that extended the maturity date and reduced the total commitment. As a result, the Partnership incurred expenses of approximately $0.6 million associated with the write-off of a portion of the related deferred financing fees. These expenses are included in interest expense in the accompanying consolidated statement of operations for the year ended December 31, 2017. Amortization expense of approximately $5.0 million, $5.4 million and $5.6 million for the years ended December 31, 2019, 2018 and 2017, respectively, is included in interest expense in the accompanying consolidated statements of operations. Supplemental cash flow information The following table presents supplemental cash flow information related to the Credit Agreement for the years ended December 31 (in thousands): 2019 2018 2017 Borrowings from working capital revolving credit facility $ 1,758,700 $ 2,002,700 $ 1,311,700 Payments on working capital revolving credit facility (1,688,100) (1,976,100) (1,509,600) Net borrowings from (payments on) working capital revolving credit facility $ 70,600 $ 26,600 $ (197,900) Borrowings from revolving credit facility $ — $ 166,000 $ 36,300 Payments on revolving credit facility (27,300) (142,000) (57,000) Net (payments on) borrowings from revolving credit facility $ (27,300) $ 24,000 $ (20,700) Senior Notes 7.00% Senior Notes Due 2027 On July 31, 2019, the Issuers issued $400.0 million aggregate principal amount of 7.00% senior notes due 2027 to the 2027 Notes Initial Purchasers in a private placement exempt from the registration requirements under the Securities Act. The Partnership used the net proceeds from the offering to fund the repurchase of the 2022 Notes in a tender offer and to repay a portion of the borrowings outstanding under its Credit Agreement. The redemption of the 2022 Notes occurred on August 30, 2019. As a result of the repurchase of the 2022 Notes, the Partnership recorded a $13.1 million loss from early extinguishment of debt for the year ended December 31, 2019, consisting of a $6.9 million cash call premium and a $6.2 million non-cash write-off of remaining unamortized original issue discount and deferred financing fees. 2027 Notes Indenture In connection with the private placement of the 2027 Notes on July 31, 2019, the Issuers and the subsidiary guarantors and Deutsche Bank Trust Company Americas, as trustee, entered into an indenture (the “2027 Notes Indenture”). The 2027 Notes will mature on August 1, 2027 with interest accruing at a rate of 7.00% per annum and payable semi-annually in arrears on February 1 and August 1 of each year, commencing February 1, 2020.

The 2027 Notes Indenture contains covenants that will limit the Partnership’s ability to, among other things, incur additional indebtedness and issue preferred securities, make certain dividends and distributions, make certain investments and other restricted payments, restrict distributions by its subsidiaries, create liens, sell assets or merge with other entities. Events of default under the 2027 Notes Indenture include (i) a default in payment of principal of, or interest or premium, if any, on, the 2027 Notes, (ii) breach of the Partnership’s covenants under the 2027 Notes Indenture, (iii) certain events of bankruptcy and insolvency, (iv) any payment default or acceleration of indebtedness of the Partnership or certain subsidiaries if the total amount of such indebtedness unpaid or accelerated exceeds $50.0 million and (v) failure to pay within 60 days uninsured final judgments exceeding $50.0 million. 2027 Notes Registration Rights Agreement On July 31, 2019, the Issuers and the subsidiary guarantors entered into a registration rights agreement (the “2027 Notes Registration Rights Agreement”) with the 2027 Notes Initial Purchasers in connection with the Issuers’ private placement of the 2027 Notes. Under the 2027 Notes Registration Rights Agreement, the Issuers and the subsidiary guarantors agreed to file and use commercially reasonable efforts to cause to become effective a registration statement relating to an offer to exchange the 2027 Notes for an issue of notes with terms identical to the 2027 Notes (except that the exchange notes will not be subject to restrictions on transfer or to any increase in annual interest rate for failure to comply with the 2027 Notes Registration Rights Agreement) that are registered under the Securities Act so as to permit the exchange offer to be consummated by September 23, 2020. The exchange offer was completed on February 18, 2020, and 100% of the 2027 Notes were exchanged for SEC-registered notes. 7.00% Senior Notes Due 2023 On June 1, 2015, the Issuers entered into a Purchase Agreement with the Initial Purchasers (as defined therein) (the “2023 Notes Initial Purchasers”) pursuant to which the Issuers agreed to sell $300.0 million aggregate principal amount of the Issuers’ 7.00% senior notes due 2023 (the “2023 Notes”) to the 2023 Notes Initial Purchasers in a private placement exempt from the registration requirements under the Securities Act. The 2023 Notes were resold by the 2023 Notes Initial Purchasers to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the United States pursuant to Regulation S under the Securities Act. 2023 Notes Indenture In connection with the private placement of the 2023 Notes on June 4, 2015 the Issuers and the subsidiary guarantors and Deutsche Bank Trust Company Americas, as trustee, entered into an indenture (the “2023 Notes Indenture”).

Upon a continuing event of default, the trustee or the holders of at least 25% in principal amount of the 2023 Notes may declare the 2023 Notes immediately due and payable, except that an event of default resulting from entry into a bankruptcy, insolvency or reorganization with respect to the Issuers, any restricted subsidiary of the Partnership that is a significant subsidiary or any group of its restricted subsidiaries that, taken together, would constitute a significant subsidiary of the Partnership, will automatically cause the 2023 Notes to become due and payable. The Issuers have the option to redeem the 2023 Notes, in whole or in part, at the redemption prices of 103.500% for the twelve-month period beginning June 15, 2019, 101.750% for the twelve-month period beginning June 15, 2020, and 100.0% beginning June 15, 2021 and at any time thereafter, together with any accrued and unpaid interest to the date of redemption.

Events of default under the 2023 Notes Indenture include (i) a default in payment of principal of, or interest or premium, if any, on, the 2023 Notes, (ii) breach of the Partnership’s covenants under the 2023 Notes Indenture, (iii) certain events of bankruptcy and insolvency, (iv) any payment default or acceleration of indebtedness of the Partnership or certain subsidiaries if the total amount of such indebtedness unpaid or accelerated exceeds $50.0 million and (v) failure to pay within 60 days uninsured final judgments exceeding $50.0 million. Financing Obligations Capitol Acquisition On June 1, 2015, the Partnership acquired retail gasoline stations and dealer supply contracts from Capitol Petroleum Group (“Capitol”). In connection with the acquisition, the Partnership assumed a financing obligation of $89.6 million associated with two sale-leaseback transactions by Capitol for 53 leased sites that did not meet the criteria for sale accounting. During the terms of these leases, which expire in May 2028 and September 2029, in lieu of recognizing lease expense for the lease rental payments, the Partnership incurs interest expense associated with the financing obligation. Interest expense of approximately $9.3 million, $9.4 million and $9.6 million was recorded for the years ended December 31, 2019, 2018 and 2017, respectively, and is included in interest expense in the accompanying consolidated statements of operations. The financing obligation will amortize through expiration of the leases based upon the lease rental payments which were $9.9 million, $9.7 million and $9.7 million for the years ended December 31, 2019, 2018 and 2017, respectively. The financing obligation balance outstanding at December 31, 2019 was $87.0 million associated with the Capitol acquisition. Sale-Leaseback Transaction On June 29, 2016, the Partnership sold to a premier institutional real estate investor (the “Buyer”) real property assets, including the buildings, improvements and appurtenances thereto, at 30 gasoline stations and convenience stores located in Connecticut, Maine, Massachusetts, New Hampshire and Rhode Island (the “Sale-Leaseback Sites”) for a purchase price of approximately $63.5 million. In connection with the sale, the Partnership entered into a Master Unitary Lease Agreement with the Buyer to lease back the real property assets sold with respect to the Sale-Leaseback Sites (such Master Lease Agreement, together with the Sale-Leaseback Sites, the “Sale-Leaseback Transaction”). The Master Unitary Lease Agreement provides for an initial term of fifteen years that expires in 2031. The Partnership has one successive option to renew the lease for a ten-year period followed by two successive options to renew the lease for five-year periods on the same terms, covenants, conditions and rental as the primary non-revocable lease term. The Partnership does not have any residual interest nor the option to repurchase any of the sites at the end of the lease term. The proceeds from the Sale-Leaseback Transaction were used to reduce indebtedness outstanding under the Partnership’s revolving credit facility. The sale did not meet the criteria for sale accounting as of December 31, 2019 due to prohibited continuing involvement. Specifically, the sale is considered a partial-sale transaction, which is a form of continuing involvement as the Partnership did not transfer to the Buyer the storage tank systems which are considered integral equipment of the Sale-Leaseback Sites. Additionally, a portion of the sold sites have material sub-lease arrangements, which is also a form of continuing involvement. As the sale of the Sale-Leaseback Sites did not meet the criteria for sale accounting, the Partnership did not recognize a gain or loss on the sale of the Sale-Leaseback Sites for the year ended December 31, 2019. As a result of not meeting the criteria for sale accounting for these sites, the Sale-Leaseback Transaction is accounted for as a financing arrangement. As such, the property and equipment sold and leased back by the Partnership has not been derecognized and continues to be depreciated. The Partnership recognized a corresponding financing obligation of $62.5 million equal to the $63.5 million cash proceeds received for the sale of these sites, net of $1.0 million financing fees. During the term of the lease, which expires in June 2031, in lieu of recognizing lease expense for the lease rental payments, the Partnership incurs interest expense associated with the financing obligation. Lease rental payments are recognized as both interest expense and a reduction of the principal balance associated with the financing obligation. Interest expense was $4.4 million for each of the years ended December 31, 2019, 2018 and 2017, and lease rental payments were $4.6 million, $4.5 million and $4.5 million for the years ended December 31, 2019, 2018 and 2017, respectively. The financing obligation balance outstanding at December 31, 2019 was $62.3 million associated with the Sale-Leaseback Transaction.

Derivative Financial Instruments	Note 9. Derivative Financial Instruments The following table summarizes the notional values related to the Partnership’s derivative instruments outstanding at December 31, 2019: Units (1) Unit of Measure Exchange-Traded Derivatives Long 51,838 Thousands of barrels Short (55,869) Thousands of barrels OTC Derivatives (Petroleum/Ethanol) Long 9,237 Thousands of barrels Short (6,934) Thousands of barrels (1) Number of open positions and gross notional values do not measure the Partnership’s risk of loss, quantify risk or represent assets or liabilities of the Partnership, but rather indicate the relative size of the derivative instruments and are used in the calculation of the amounts to be exchanged between counterparties upon settlements. Derivatives Accounted for as Hedges Fair Value Hedges The Partnership’s fair value hedges include exchange-traded futures contracts and OTC derivative contracts that are hedges against inventory with specific futures contracts matched to specific barrels. The change in fair value of these futures contracts and the change in fair value of the underlying inventory generally provide an offset to each other in the consolidated statement of operations. The following table presents the gains and losses from the Partnership’s derivative instruments involved in fair value hedging relationships recognized in the consolidated statements of operations for the years ended December 31 (in thousands): Statement of Gain (Loss) Recognized in Income on Derivatives 2019 2018 2017 Derivatives in fair value hedging relationship Exchange-traded futures contracts and OTC derivative contracts for petroleum commodity products Cost of sales $ 10,640 $ 5,566 $ 26,118 Hedged items in fair value hedge relationship Physical inventory Cost of sales $ (10,532) $ (9,686) $ (23,247) Cash Flow Hedges The Partnership had no cash flow hedges in 2019. The Partnership’s cash flow hedges in 2018 and 2017 primarily included one interest rate swap which became effective on October 2, 2013 and expired on October 2, 2018 and was used to hedge the variability in cash flows in monthly interest payments due to changes in the one month LIBOR swap curve with respect to $100.0 million of one month LIBOR based borrowings on the credit facility at a fixed rate of 1.819%. The amount of gain (loss) recognized in other comprehensive income as effective for derivatives designated in cash flow hedging relationships was $0.1 million and $1.0 million for the years ended December 31, 2018 and 2017. The amount of gain (loss) recognized in income as ineffectiveness for derivatives designated in cash flow hedging relationships was $0 for each of the years ended December 31, 2018 and 2017. Derivatives Not Accounted for as Hedges The following table presents the gains and losses from the Partnership’s derivative instruments not involved in a hedging relationship recognized in the consolidated statements of operations for the years ended December 31 (in thousands): Statement of Gain (Loss) Derivatives not designated as Recognized in hedging instruments Income on Derivatives 2019 2018 2017 Commodity contracts Cost of sales $ 14,528 $ 3,783 $ 9,502 Commodity Contracts and Other Derivative Activity The Partnership’s commodity contracts and other derivative activity include: (i) exchange-traded derivative contracts that are hedges against inventory and either do not qualify for hedge accounting or are not designated in a hedge accounting relationship, (ii) exchange-traded derivative contracts used to economically hedge physical forward contracts, (iii) financial forward and OTC swap agreements used to economically hedge physical forward contracts and (iv) the derivative instruments under the Partnership’s controlled trading program. The Partnership does not take the normal purchase and sale exemption available under ASC 815 for any of its physical forward contracts. The following table presents the fair value of each classification of the Partnership’s derivative instruments and its location in the consolidated balance sheets at December 31, 2019 and 2018 (in thousands): December 31, 2019 Derivatives Derivatives Not Designated as Designated as Hedging Hedging Balance Sheet Location Instruments Instruments Total Asset Derivatives: Exchange-traded derivative contracts Broker margin deposits $ — $ 31,645 $ 31,645 Forward derivative contracts (1) Derivative assets — 4,564 4,564 Total asset derivatives $ — $ 36,209 $ 36,209 Liability Derivatives: Exchange-traded derivative contracts Broker margin deposits $ (3,838) $ (26,354) $ (30,192) Forward derivative contracts (1) Derivative liabilities — (12,698) (12,698) Total liability derivatives $ (3,838) $ (39,052) $ (42,890) December 31, 2018 Derivatives Derivatives Not Designated as Designated as Hedging Hedging Balance Sheet Location Instruments Instruments Total Asset Derivatives: Exchange-traded derivative contracts Broker margin deposits $ 5,121 $ 120,992 $ 126,113 Forward derivative contracts (1) Derivative assets — 26,390 26,390 Total asset derivatives $ 5,121 $ 147,382 $ 152,503 Liability Derivatives: Exchange-traded derivative contracts Broker margin deposits $ — $ (42,496) $ (42,496) Forward derivative contracts (1) Derivative liabilities — (4,494) (4,494) Total liability derivatives $ — $ (46,990) $ (46,990) (1) Forward derivative contracts include the Partnership’s petroleum and ethanol physical and financial forwards and OTC swaps. Credit Risk The Partnership’s derivative financial instruments do not contain credit risk related to other contingent features that could cause accelerated payments when these financial instruments are in net liability positions. The Partnership is exposed to credit loss in the event of nonperformance by counterparties to the Partnership’s exchange-traded and OTC derivative contracts, but the Partnership has no current reason to expect any material nonperformance by any of these counterparties. Exchange-traded derivative contracts, the primary derivative instrument utilized by the Partnership, are traded on regulated exchanges, greatly reducing potential credit risks. The Partnership utilizes major financial institutions as its clearing brokers for all New York Mercantile Exchange (“NYMEX”), Chicago Mercantile Exchange (“CME”) and Intercontinental Exchange (“ICE”) derivative transactions and the right of offset exists with these financial institutions under master netting agreements. Accordingly, the fair value of the Partnership’s exchange-traded derivative instruments is presented on a net basis in the consolidated balance sheets. Exposure on OTC derivatives is limited to the amount of the recorded fair value as of the balance sheet dates.

Fair Value Measurements
Fair Value Measurements	Note 10. Fair Value Measurements Recurring Fair Value Measures Assets and liabilities are classified in the entirety based on the lowest level of input that is significant to the fair value measurement. The Partnership’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of the fair value assets and liabilities and their placement within the fair value hierarchy levels. The following tables present, by level within the fair value hierarchy, the Partnership’s financial assets and liabilities that were measured at fair value on a recurring basis as of December 31, 2019 and 2018 (in thousands): Fair Value at December 31, 2019 Cash Collateral Level 1 Level 2 Level 3 Netting Total Assets: Forward derivative contracts (1) $ — $ 4,002 $ 562 $ — $ 4,564 Exchange-traded/cleared derivative instruments (2) 1,453 — — 33,013 34,466 Pension plans 17,099 — — — 17,099 Total assets $ 18,552 $ 4,002 $ 562 $ 33,013 $ 56,129 Liabilities: Forward derivative contracts (1) $ — $ (12,112) $ (586) $ — $ (12,698) Fair Value at December 31, 2018 Cash Collateral Level 1 Level 2 Level 3 Netting Total Assets: Forward derivative contracts (1) $ — $ 25,504 $ 886 $ — $ 26,390 Exchange-traded/cleared derivative instruments (2) 83,617 — — (68,851) 14,766 Pension plans 15,800 — — — 15,800 Total assets $ 99,417 $ 25,504 $ 886 $ (68,851) $ 56,956 Liabilities: Forward derivative contracts (1) $ — $ (3,878) $ (616) $ — $ (4,494) (1) Forward derivative contracts include the Partnership’s petroleum and ethanol physical and financial forwards and OTC swaps (2) Amount includes the effect of cash balances on deposit with clearing brokers. This table excludes cash on hand and assets and liabilities that are measured at historical cost or any basis other than fair value. The carrying amounts of certain of the Partnership’s financial instruments, including cash equivalents, accounts receivable, accounts payable and other accrued liabilities approximate fair value due to their short maturities. The carrying value of the credit facility approximates fair value due to the variable rate nature of these financial instruments. The carrying value of the inventory qualifying for fair value hedge accounting approximates fair value due to adjustments for changes in fair value of the hedged item. The fair values of the derivatives used by the Partnership are disclosed in Note 9. The determination of the fair values above incorporates factors including not only the credit standing of the counterparties involved, but also the impact of the Partnership’s nonperformance risks on its liabilities. The values of the Level 1 exchange-traded/cleared derivative instruments and pension plan assets were determined using quoted prices in active markets for identical assets. Specifically, the fair values of the Level 1 exchange-traded/cleared derivative instruments were based on quoted process obtained from the NYMEX, CME and ICE. The fair values of the Level 1 pension plan assets were based on quoted prices for identical assets which primarily consisted of fixed income securities, equity securities and cash and cash equivalents. The values of the Level 2 derivative contracts were calculated using expected cash flow models and market approaches based on observable market inputs, including published and quoted commodity pricing data, which is verified against other available market data. Specifically, the fair values of the Level 2 derivative commodity contracts were derived from published and quoted NYMEX, CME, ICE, New York Harbor and third-party pricing information for the underlying instruments using market approaches. The fair value of the Level 2 interest rate instruments was derived from the implied forward LIBOR yield curve for the sale period as the future interest rate swap settlements using expected cash flow models. The Partnership has not changed its valuation techniques or Level 2 inputs during the years ended December 31, 2019 and 2018. The Partnership estimates the fair values of its senior notes using a combination of quoted market prices for similar financing arrangements and expected future payments discounted at risk-adjusted rates, which are considered Level 2 inputs. The fair values of the senior notes, estimated by observing market trading prices of the respective senior notes, were as follows at December 31 (in thousands): 2019 2018 Face Fair Face Fair Value Value Value Value 6.25% senior notes due 2022 $ — $ — $ 375,000 $ 363,750 7.00% senior notes due 2023 $ 300,000 $ 309,000 $ 300,000 $ 294,000 7.00% senior notes due 2027 $ 400,000 $ 423,000 $ — $ — Level 3 Information The values of the Level 3 derivative contracts were calculated using market approaches based on a combination of observable and unobservable market inputs, including published and quoted NYMEX, CME, ICE, New York Harbor and third-party pricing information for a component of the underlying instruments as well as internally developed assumptions where there is little, if any, published or quoted prices or market activity. The unobservable inputs used in the measurement of the Level 3 derivative contracts include estimates for location basis, transportation and throughput costs net of an estimated margin for current market participants. The estimates for these inputs for crude oil were ($4.95) to ($3.25) per barrel and ($3.25) to $2.00 per barrel as of December 31, 2019 and 2018, respectively. The estimates for these inputs for propane were $0.84 to $15.54 per barrel and $0.84 to $10.50 per barrel as of December 31, 2019 and 2018, respectively. Gains and losses recognized in earnings (or changes in net assets) are disclosed in Note 9. Sensitivity of the fair value measurement to changes in the significant unobservable inputs is as follows: Significant Impact on Fair Value Unobservable Input Position Change to Input Measurement Location basis Long Increase (decrease) Gain (loss) Location basis Short Increase (decrease) Loss (gain) Transportation Long Increase (decrease) Gain (loss) Transportation Short Increase (decrease) Loss (gain) Throughput costs Long Increase (decrease) Gain (loss) Throughput costs Short Increase (decrease) Loss (gain) The following table presents a reconciliation of changes in fair value of the Partnership’s derivative contracts classified as Level 3 in the fair value hierarchy at December 31 (in thousands): Fair value at December 31, 2018 $ 270 Derivatives entered into during the period 502 Derivatives sold during the period (467) Realized gains (losses) recorded in cost of sales (241) Unrealized gains (losses) recorded in cost of sales (88) Fair value at December 31, 2019 $ (24) The Partnership’s policy is to recognize transfers between levels with the fair value hierarchy as of the beginning of the reporting period. The Partnership also excludes any activity for derivative instruments that were not classified as Level 3 at either the beginning or end of the reporting period. Non-Recurring Fair Value Measures Certain nonfinancial assets and liabilities are measured at fair value on a non-recurring basis and are subject to fair value adjustments in certain circumstances, such as acquired assets and liabilities, losses related to firm non-cancellable purchase commitments or long-lived assets subject to impairment. For assets and liabilities measured on a non-recurring basis during the year, accounting guidance requires quantitative disclosures about the fair value measurements separately for each major category. See Note 2 for a discussion of the Partnership’s losses on impairment of assets, Note 7 for assets held for sale and Note 20 for acquired assets and liabilities measured on a non-recurring basis.

The following provides total future minimum payments under the agreement with non‑cancellable terms of one year or more at December 31, 2019 (in thousands): 2020 $ 9,000 2021 9,000 2022 9,000 2023 9,000 2024 9,000 Thereafter 4,500 Total $ 49,500 Total expenses reflected in cost of sales related to this agreement were approximately $9.0 million for each of the years ended December 31, 2019, 2018 and 2017. Other Commitments In June 2014, the Partnership entered into a pipeline connection agreement with Meadowlark Midstream Company, LLC (“Meadowlark”) whereby Meadowlark would construct, own, operate and maintain a crude oil pipeline from its Divide County, North Dakota crude oil station to the Partnership’s Basin Transload crude oil storage facility in Columbus, North Dakota. In connection with the agreement, the Partnership was committed to a minimum take-or-pay throughput commitment of approximately $55.0 million over a seven–year period beginning after the commissioning of the pipeline which occurred in December of 2015. At December 31, 2019, the remaining commitment on the take-or-pay commitment was approximately $25.0 million. In May 2014, the Partnership entered into a pipeline connection agreement with Tesoro High Plains Pipeline Company (“Tesoro High Plains”) whereby Tesoro High Plains would design, engineer, construct and place in service improvements on its pipeline system that will expand its capacity to ship crude oil from points in Dunn and McKenzie Counties, North Dakota to Ramberg Station/Beaver Lodge destination point in Williams County, North Dakota. In connection with this agreement, the Partnership was committed to a minimum take-or-pay throughput commitment of approximately $36.4 million over a seven–year period beginning September 1, 2014. At December 31, 2019, the remaining commitment on the take-or-pay commitment, including a quarterly take-or-pay of $1.5 million, was approximately $9.9 million. In April 2014, Basin Transload, of which the Partnership owns a 60% membership interest, entered into a pipeline connection agreement with Tesoro Logistics (“Tesoro”) whereby Tesoro would build, own and operate a four‑mile pipeline lateral from its existing block gate valve in Mercer Country, North Dakota to the Partnership’s Beulah Rail Facility near Beulah, North Dakota. In connection with this agreement, Basin Transload was committed to a minimum take-or-pay throughput commitment of approximately $14.6 million over a five‑year period beginning after the commissioning of the pipeline, which occurred in January 2015. During the third quarter of 2017, this agreement was accelerated by Tesoro due to a lack of crude oil movement through the pipeline, and the Partnership recorded a $13.1 million expense. In October 2017, the Partnership paid the $13.1 million to Tesoro associated with the acceleration and corresponding termination of this agreement. At December 31, 2019, the remaining commitment on the take-or-pay commitment was $0. In February 2013, the Partnership assumed natural gas transportation and reservation agreements, which have various expiration dates, with Northwest Natural Gas Company (“NW Natural Gas”) and the Northwest Pipeline system (“NW Pipeline”) whereby NW Natural Gas and NW Pipeline provide the Partnership with the transportation and reservation of firm natural gas delivered to the Partnership’s Oregon facility.

Income Taxes	Note 13 Income Taxes GMG, a wholly owned subsidiary of the Partnership, is a taxable entity for federal and state income tax purposes. Current and deferred income taxes are recognized on the separate earnings of GMG, and the after‑tax earnings of GMG are included in the consolidated earnings of the Partnership. The following table presents a reconciliation of the difference between the statutory federal income tax rate and the effective income tax rate for the years ended December 31: 2019 2018 2017 Federal statutory income tax rate 21.0 % 21.0 % 35.0 % State income tax rate, net of federal tax benefit 2.9 % 2.8 % 1.2 % Derecognition of goodwill 0.5 % 0.3 % 1.6 % Federal deferred rate change — % — % (65.5) % Partnership income not subject to tax (21.4) % (18.9) % (42.5) % Effective income tax rate 3.0 % 5.2 % (70.2) % The following table presents the components of the provision for income taxes for the years ended December 31 (in thousands): 2019 2018 2017 Current: Federal $ 35 $ 162 $ 1,371 State 1,036 2,706 1,011 Foreign — 4 4 Total current 1,071 2,872 2,386 Deferred: Federal 815 1,961 (25,217) State (792) 790 (732) Total deferred 23 2,751 (25,949) Total $ 1,094 $ 5,623 $ (23,563) Significant components of long‑term deferred taxes were as follows at December 31 (in thousands): 2019 2018 Deferred Income Tax Assets Accounts receivable allowances $ 751 $ 760 Environmental liability 9,414 9,943 Asset retirement obligation 2,146 2,344 Deferred financing obligation 11,394 11,405 UNICAP 8 56 Lease liability 44,578 — Other 1,471 1,384 Federal net operating loss carryforwards 18,505 14,811 State net operating loss carryforwards 1,134 1,087 Tax credit carryforward 691 284 Total deferred tax assets, gross 90,092 42,074 Valuation allowance (3,299) (3,138) Total deferred tax assets, net $ 86,793 $ 38,936 Deferred Income Tax Liabilities Property and equipment $ (74,031) $ (69,356) Land (12,353) (12,189) Other deferred tax liabilities (748) — Right of use assets (42,536) — Intangible assets (4) (247) Total deferred tax liabilities $ (129,672) $ (81,792) Net deferred tax liabilities $ (42,879) $ (42,856) The Partnership’s net deferred tax liabilities are primarily comprised of the differences in the historical tax basis and fair value book basis of property, equipment and land that were acquired in connection with the 2015 acquisition of Warren Equities, Inc. (“Warren”). At December 31, 2019, GMG had federal and state net operating loss carryforwards of approximately $8.9 million and $18.9 million, respectively, which will begin to expire in 2034 and 2026, respectively. In addition, GMG had federal and state net operating loss carryforwards of approximately $66.8 and $0.2 million, respectively, which can be carried forward indefinitely. Utilization of the net operating loss carryforwards may be subject to annual limitations due to the ownership percentage change limitations provided by the Internal Revenue Code Section 382 and similar state provisions. In the event of a deemed change in control under Internal Revenue Code Section 382, an annual limitation imposed on the utilization of net operating losses may result in the expiration of all or a portion of the net operating loss carryforwards. At December 31, 2019, the Partnership had $30.5 million of net deferred tax liabilities (consisting of the $42.9 million total net deferred tax liability less the $12.4 million deferred tax liability relating to land discussed below) relating to property and equipment, net operating loss carryforwards, tax credit carryforwards and other temporary differences, certain of which are available to reduce income taxes in future years. The Partnership recognizes deferred tax assets to the extent that the recoverability of these assets satisfies the “more likely than not” criteria in accordance with the FASB’s guidance regarding income taxes. A valuation allowance must be established when it is “more likely than not” that all or a portion of deferred tax assets will not be realized. A review of all available positive and negative evidence needs to be considered, including a company’s performance, the market environment in which the company operates, length of carryback and carryforward periods and projections of future operating results. The Partnership concluded, based on an evaluation of future operating results and reversal of existing taxable temporary differences, that a portion of these assets will not be realized in a future period. The valuation allowance increased by approximately $0.2 million as of December 31, 2019. At December 31, 2019, the Partnership also had a $12.4 million deferred tax liability relating to land. Land is an asset with an indefinite useful life and would not ordinarily serve as a source of income for the realization of deferred tax assets. This deferred tax liability will not reverse until some indefinite future period when the asset is either sold or written down due to impairment. Such taxable temporary differences generally cannot be used as a source of taxable income to support the realization of deferred tax assets relating to reversing deductible temporary differences, including loss carryforwards with expiration periods. It can be used as a source of income to benefit other indefinite lived assets. The following presents a reconciliation of the differences between income before income tax (expense) benefit and (loss) income subject to income tax expense for the years ended December 31 (in thousands): 2019 2018 2017 Income before income tax (expense) benefit $ 36,272 $ 108,026 $ 33,554 Less non—taxable income 37,001 97,561 40,904 (Loss) income subject to income tax expense $ (729) $ 10,465 $ (7,350) The Partnership made approximately ($5.2 million), $0.7 million and $7.4 million in income tax payments, net of refunds received, during 2019, 2018 and 2017, respectively. The ($5.2 million) in 2019 consists of tax refunds of ($7.6 million) received associated with the Warren amended returns for periods prior to the acquisition of Warren on January 27, 2015 and ($0.2 million) of other tax refunds, offset by $2.6 million in income tax payments. In accordance with the stock purchase agreement between the Partnership and Warren, the Partnership is ultimately not responsible for federal income tax obligations for tax periods prior to and through January 6, 2015. Any tax obligations will be funded by the selling shareholders, and any tax refunds will be remitted to the selling shareholders. GMG files income tax returns in the United States and various state jurisdictions. With few exceptions, the Partnership is subject to income tax examinations by tax authorities for all years dated back to 2016. The following presents the changes in gross unrealized tax benefits for the years ended December 31 (in thousands): 2019 2018 2017 Balance at beginning of year $ 994 $ 994 $ 1,433 Increases for tax positions taken in prior years — — 28 Settlements of tax positions taken in prior years — — (467) Income subject to income tax expense $ 994 $ 994 $ 994 Unrecognized tax benefits represent uncertain tax positions for which reserves have been established. The Partnership had gross-tax effected unrecognized tax benefits of $1.0 million for each of the years ended December 31, 2019, 2018 and 2017, all of which would favorably impact the effective tax rate if recognized. The FASB’s accounting guidance for income taxes clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements by prescribing a minimum recognition threshold and measurement of a tax position taken or expected to be taken in a tax return. The Partnership performed an evaluation of all material tax positions for the tax years that remain subject to examination by major tax jurisdictions as of December 31, 2019 (tax years ended December 31, 2019, 2018 and 2017). Tax positions that do not meet 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. The Partnership classifies interest and penalties related to income taxes as components of its provision for income taxes. The amount of interest and penalties recorded in the accompanying statements of operations was $0.1 million, $0.1 million and $0 for the years ended December 31, 2019, 2018 and 2017, respectively. The amount of interest and penalties recorded in the accompanying consolidated balance sheets was $0.2 million as of both December 31, 2019 and 2018. The Partnership anticipates that the liability for unrecognized tax benefits for uncertain tax positions could change by up to $1.0 million in the next twelve months as a result of closure of various statutes of limitations.

Environmental Liabilities and Renewable Identification Numbers (RINs)
Environmental Liabilities and Renewable Identification Numbers (RINs)	Note 14. Environmental Liabilities and Renewable Identification Numbers (RINs) Environmental Liabilities The Partnership owns or leases properties where refined petroleum products, gasoline blendstocks, renewable fuels and crude oil are being or may have been handled. These properties and the refined petroleum products, gasoline blendstocks, renewable fuels and crude oil handled thereon may be subject to federal and state environmental laws and regulations. Under such laws and regulations, the Partnership 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 clean up contaminated property arising from the release of liquids, pollutants or wastes into the environment, including contaminated groundwater, or to implement best management practices to prevent future contamination. The Partnership maintains insurance of various types with varying levels of coverage that it considers adequate under the circumstances to cover its operations and properties. The insurance policies are subject to deductibles that the Partnership considers reasonable and not excessive. In addition, the Partnership has entered into indemnification agreements with various sellers in conjunction with several of its acquisitions. Certain environmental remediation obligations at several acquired retail gasoline station assets from Capitol in June 2015 and Alliance Energy LLC (“Alliance”) in March 2012 are being funded by third parties who assumed certain liabilities in connection with Capitol’s acquisition of these assets from ExxonMobil in 2009 and 2010 and Alliance’s acquisition of these assets from ExxonMobil in 2011 and, therefore, cost estimates for such obligations at these stations are not included in this estimate of liability to the Partnership. Allocation of a known environmental liability is an issue negotiated in connection with each of the Partnership’s acquisition transactions. In each case, the Partnership makes an assessment of potential environmental liability exposure based on available information. Based on that assessment and relevant economic and risk factors, the Partnership determines whether to, and the extent to which it will, assume liability for existing environmental conditions. The following table presents a summary roll forward of the Partnership’s environmental liabilities, which were recorded on an undiscounted basis, at December 31, 2019 (in thousands): Balance at Other Balance at December 31, Payments Dispositions Adjustments December 31, Environmental Liability Related to: 2018 2019 2019 2019 2019 Retail gasoline stations $ 59,133 $ (3,129) $ (1,425) $ 914 $ 55,493 Terminals 4,091 (313) — — 3,778 Total environmental liabilities $ 63,224 $ (3,442) $ (1,425) $ 914 $ 59,271 Current portion $ 6,092 $ 5,009 Long-term portion 57,132 54,262 Total environmental liabilities $ 63,224 $ 59,271 In addition to environmental liabilities related to the Partnership’s retail gasoline stations, the Partnership retains some of the environmental obligations associated with certain gasoline stations that the Partnership has sold. The Partnership’s estimates used in these environmental liabilities are based on all known facts at the time and its assessment of the ultimate remedial action outcomes. Among the many uncertainties that impact the Partnership’s estimates are the necessary regulatory approvals for, and potential modification of, its 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, relief of obligations through divestitures of sites and the possibility of existing legal claims giving rise to additional claims. Dispositions generally represent relief of legal obligations through the sale of the related property with no retained obligation. Other adjustments generally represent changes in estimates for existing obligations or obligations associated with new sites. Therefore, although the Partnership believes that these environmental liabilities are adequate, no assurances can be made that any costs incurred in excess of these environmental liabilities or outside of indemnifications or not otherwise covered by insurance would not have a material adverse effect on the Partnership’s financial condition, results of operations or cash flows. Renewable Identification Numbers (RINs) A RIN is a serial number assigned to a batch of renewable fuel for the purpose of tracking its production, use, and trading as required by the U.S. Environmental Protection Agency’s (“EPA”) Renewable Fuel Standard that originated with the Energy Policy Act of 2005 and modified by the Energy Independence and Security Act of 2007. To evidence that the required volume of renewable fuel is blended with gasoline and diesel motor vehicle fuels, obligated parties must retire sufficient RINs to cover their Renewable Volume Obligation (“RVO”). The Partnership’s EPA obligations relative to renewable fuel reporting are comprised of foreign gasoline and diesel that the Partnership may import and blending operations at certain facilities. As a wholesaler of transportation fuels through its terminals, the Partnership separates RINs from renewable fuel through blending with gasoline and can use those separated RINs to settle its RVO. While the annual compliance period for the RVO is a calendar year and the settlement of the RVO typically occurs by March 31 of the following year, the settlement of the RVO can occur, under certain EPA deferral actions, more than one year after the close of the compliance period. The Partnership’s Wholesale segment’s operating results may be sensitive to the timing associated with its RIN position relative to its RVO at a point in time, and the Partnership may recognize a mark‑to‑market liability for a shortfall in RINs at the end of each reporting period. To the extent that the Partnership does not have a sufficient number of RINs to satisfy the RVO as of the balance sheet date, the Partnership charges cost of sales for such deficiency based on the market price of the RINs as of the balance sheet date and records a liability representing the Partnership’s obligation to purchase RINs. The Partnership’s RVO deficiency was $0.9 million and $0.6 million at December 31, 2019 and 2018, respectively. The Partnership may enter into RIN forward purchase and sales commitments. Total losses from firm non-cancellable commitments were immaterial at both December 31, 2019 and 2018.

Employee Benefit Plans
Employee Benefit Plans	Note 15. Employee Benefit Plans The Partnership sponsors and maintains the Global Partners LP 401(k) Savings and Profit Sharing Plan (the “Global 401(k) Plan”), a qualified defined contribution plan. Eligible employees may elect to contribute up to 100% of their eligible compensation to the Global 401(k) Plan for each payroll period, subject to annual dollar limitations which are periodically adjusted by the IRS. The General Partner makes safe harbor matching contributions to the Global Partners 401(k) Plan equal to 100% of the participant’s elective contributions that do not exceed 3% of the participant’s eligible compensation and 50% of the participant’s elective contributions that exceed 3% but do not exceed 5% of the participant’s eligible compensation. The General Partner also makes discretionary non‑matching contributions for certain groups of employees in amounts up to 2% of eligible compensation. Profit‑sharing contributions may also be made at the sole discretion of the General Partner’s board of directors. GMG sponsors and maintains the Global Montello Group Corp. 401(k) Savings and Profit Sharing Plan (the “GMG 401(k) Plan”), a qualified defined contribution plan. Eligible employees may elect to contribute up to 100% of their eligible compensation to the GMG 401(k) Savings and Profit Sharing Plan for each payroll period, subject to annual dollar limitations which are periodically adjusted by the IRS. GMG makes safe harbor matching contributions to the 401(k) Savings and Profit Sharing Plan equal to 100% of the participant’s elective contributions that do not exceed 3% of the participant’s eligible compensation and 50% of the participant’s elective contributions that exceed 3% but do not exceed 5% of the participant’s eligible compensation. Profit‑sharing contributions may also be made at the sole discretion of GMG’s board of directors. The Global 401(k) Plan and the GMG 401(k) Plan collectively had expenses of approximately $3.5 million, $3.1 million and $3.0 million for the years ended December 31, 2019, 2018 and 2017, respectively. In addition, the General Partner sponsors and maintains the Global Partners LP Pension Plan (the “Global Pension Plan),” and GMG sponsors and maintains the Global Montello Group Corp. Pension Plan (the “GMG Pension Plan”), each being a qualified defined benefit pension plan. The Global Pension Plan and the GMG Pension Plan were amended to freeze participation and benefit accruals effective in 2009 and 2012, respectively. The following table presents each plan’s funded status and the total amounts recognized in the consolidated balance sheets at December 31 (in thousands): December 31, 2019 Global GMG Pension Plan Pension Plan Total Projected benefit obligation $ 17,030 $ 4,459 $ 21,489 Fair value of plan assets 14,267 2,832 17,099 Net unfunded pension liability $ 2,763 $ 1,627 $ 4,390 December 31, 2018 Global GMG Pension Plan Pension Plan Total Projected benefit obligation $ 16,213 $ 3,873 $ 20,086 Fair value of plan assets 13,372 2,428 15,800 Net unfunded pension liability $ 2,841 $ 1,445 $ 4,286 Total actual return on plan assets was $3.9 million and ($0.7 million) in 2019 and 2018, respectively. The following presents the components of the net periodic change in benefit obligation for the Pension Plans for the years ended December 31 (in thousands): 2019 2018 2017 Benefit obligation at beginning of year $ 20,086 $ 22,217 $ 20,631 Interest cost 767 714 724 Actuarial (gain) loss 3,839 (1,347) 2,392 Benefits paid (3,203) (1,498) (1,530) Benefit obligation at end of year $ 21,489 $ 20,086 $ 22,217 The following presents the weighted-average actuarial assumptions used in determining each plan’s annual pension expense for the years ended December 31: Global Pension Plan GMG Pension Plan 2019 2018 2017 2019 2018 2017 Discount rate 3.0% 4.1% 3.4% 3.2% 4.2% 3.6% Expected return on plan assets 7.0% 7.0% 7.0% 7.0% 7.0% 7.0% The discount rates were selected by performing a cash flow/bond matching analysis based on the FTSE Above Median Double-A Pension Discount Curve for December 2019. The discount rates for 2019 include updated mortality assumptions to reflect the most recently available mortality improvement scale released by the Society of Actuaries. The expected long-term rate of return on plan assets is determined by using each plan’s respective target allocation and historical returns for each asset class. The fundamental investment objective of each of the Pension Plans is to provide a rate of return sufficient to fund the retirement benefits under the applicable Pension Plan at a reasonable cost to the applicable plan sponsor. At a minimum, the rate of return should equal or exceed the discount rate assumed by the Pension Plan’s actuaries in projecting the funding cost of the Pension Plan under the applicable Employee Retirement Income Security Act (“ERISA”) standards. To do so, the General Partner’s Pension Committee may appoint one or more investment managers to invest all or portions of the assets of the Pension Plans in accordance with specific investment guidelines, objectives, standards and benchmarks. The following presents the Pension Plans’ benefits as of December 31, 2019 expected to be paid in each of the next five fiscal years and in the aggregate for the next five fiscal years thereafter (in thousands): 2020 $ 1,647 2021 1,072 2022 1,281 2023 920 2024 942 2025—2029 7,782 Total $ 13,644 The cost of annual contributions to the Pension Plans is not significant to the General Partner, the Partnership or its subsidiaries. Total contributions made by the General Partner, the Partnership and its subsidiaries to the Pension Plans were approximately $0.6 million, $0.4 million and $0.4 million in 2019, 2018 and 2017, respectively.

Related Party Transactions	Note 16. Related‑Party Transactions The Partnership is a party to a Second Amended and Restated Services Agreement with Global Petroleum Corp. (“GPC”), an affiliate of the Partnership that is 100% owned by members of the Slifka family, pursuant to which the Partnership provides GPC with certain tax, accounting, treasury, legal, information technology, human resources and financial operations support services for which GPC pays the Partnership a monthly services fee at an agreed amount subject to the approval by the Conflicts Committee of the board of directors of the General Partner. The Second Amended and Restated Services Agreement is for an indefinite term and any party may terminate some or all of the services upon ninety (90) days’ advanced written notice. As of December 31, 2019, no such notice of termination was given by GPC or the Partnership. The General Partner employs substantially all of the Partnership’s employees, except for most of its gasoline station and convenience store employees, who are employed by GMG. The Partnership reimburses the General Partner for expenses incurred in connection with these employees. These expenses, including bonus, payroll and payroll taxes, were $118.5 million, $104.8 million and $106.0 million for the years ended December 31, 2019, 2018 and 2017, respectively. The Partnership also reimburses the General Partner for its contributions under the General Partner’s 401(k) Savings and Profit Sharing Plans (see Note 15) and the General Partner’s qualified and non‑qualified pension plans. The table below presents receivables from GPC and the General Partner at December 31 (in thousands): 2019 2018 Receivables from GPC $ 53 $ 23 Receivables from the General Partner (1) 7,770 5,412 Total $ 7,823 $ 5,435 (1) Receivables from the General Partner reflect the Partnership’s prepayment of payroll taxes and payroll accruals to the General Partner and are due to the timing of the payroll obligations. In addition, for the years ended December 31, 2019, 2018 and 2017, the Partnership paid certain costs in connection with a compensation funding agreement with the General Partner. See Note 17, “Long-Term Incentive Plan–Repurchase Program.”

Long-Term Incentive Plan

Long-Term Incentive Plan
Long-Term Incentive Plan	Note 17. Long-Term Incentive Plans The Partnership has a Long Term Incentive Plan, as amended (the “LTIP”), whereby a total of 4,300,000 common units were authorized for delivery with respect to awards under the LTIP. The LTIP provides for awards to employees, consultants and directors of the General Partner and employees and consultants of affiliates of the Partnership who perform services for the Partnership. The LTIP allows for the award of options, unit appreciation rights, restricted units, phantom units, distribution equivalent rights, unit awards and substitute awards. Awards granted pursuant to the LTIP vest pursuant to the terms of the grant agreements. A total of 3,016,234 units were available for issuance under the LTIP as of December 31, 2019. Awards granted under the LTIP are authorized by the Compensation Committee of the board of directors of the General Partner (the “Committee”) from time to time. Additionally, and in accordance with the LTIP, the Committee established a “CEO Authorized LTIP” program pursuant to which the Chief Executive Officer (“CEO”) could grant awards of phantom units without distribution equivalent rights to employees of the General Partner and the Partnership’s subsidiaries, other than named executive officers. The CEO Authorized LTIP program was approved for three consecutive calendar years and expired on December 31, 2017. During each calendar year of the program, the CEO was authorized to grant awards of up to an aggregate amount of $2.0 million of phantom units payable in common units upon vesting, with unused dollar amounts carrying over in the next year, and no individual grant could be made for an award valued at the time of grant of more than $550,000, unless otherwise previously approved by the Committee. Awards granted pursuant to the CEO Authorized LTIP generally were for a term of six years and vest in equal tranches at the end of each of the fourth, fifth and sixth anniversary dates of the particular award. The following table presents a summary of the non‑vested phantom units granted under the LTIP: Weighted Number of Average Non-vested Grant Date Units Fair Value ($) Outstanding non—vested units at December 31, 2017 912,564 15.99 Vested (153,966) 27.93 Forfeited (28,457) 13.40 Outstanding non—vested phantom units at December 31, 2018 730,141 13.57 Vested (148,842) 27.41 Forfeited (18,393) 18.66 Outstanding non—vested phantom units at December 31, 2019 562,906 9.74 Accounting guidance for share‑based compensation requires that a non‑vested equity share unit awarded to an employee is to be measured at its fair value as if it were vested and issued on the grant date. Compensation cost for an award of share-based employee compensation classified as equity is recognized over the requisite service period. The requisite service period for the Partnership is from the grant date through the vesting dates described in the grant agreement. The Partnership recognizes as compensation expense for the awards granted to employees and non-employee directors the value of the portion of the award that is ultimately expected to vest over the requisite service period on a straight-line basis. The Partnership recognizes forfeitures as they occur. The Partnership recorded total compensation expense related to the outstanding LTIP awards of $2.0 million, $3.1 million and $3.9 million for the years ended December 31, 2019, 2018 and 2017, respectively, which is included in selling, general and administrative expenses in the accompanying consolidated statements of operations. The total compensation cost related to the non-vested awards not yet recognized at December 31, 2019 was approximately $2.7 million and is expected to be recognized ratably over the remaining requisite service periods. Repurchase Program In May 2009, the board of directors of the General Partner authorized the repurchase of the Partnership’s common units (the “Repurchase Program”) for the purpose of meeting the General Partner’s anticipated obligations to deliver common units under the LTIP and meeting the General Partner’s obligations under existing employment agreements and other employment related obligations of the General Partner (collectively, the “General Partner’s Obligations”). The General Partner is authorized to acquire up to 1,242,427 of its common units in the aggregate over an extended period of time, consistent with the General Partner’s Obligations. Common units may be repurchased from time to time in open market transactions, including block purchases, or in privately negotiated transactions. Such authorized unit repurchases may be modified, suspended or terminated at any time and are subject to price and economic and market conditions, applicable legal requirements and available liquidity. Since the Repurchase Program was implemented, the General Partner repurchased 838,505 common units pursuant to the Repurchase Program for approximately $24.8 million, none of which were repurchased in 2019. In June 2009, the Partnership and the General Partner entered into the Global GP LLC Compensation Funding Agreement (the “Agreement”) whereby the Partnership and the General Partner established obligations and protocol for (i) the funding, management and administration of a compensation funding account and underlying General Partner’s Obligations, and (ii) the holding and disposition by the General Partner of common units acquired in accordance with the Agreement for such purposes as otherwise set forth in the Agreement. The Agreement requires the Partnership to fund costs that the General Partner incurs in connection with performance of the Agreement. In accordance with the Agreement, the Partnership paid members of the General Partner approximately $0.3 million and $0.4 million of these costs for the years ended December 31, 2019 and 2018, respectively.

Partners' Equity, Allocations and Cash Distributions	Note 18. Partners’ Equity, Allocations and Cash Distributions Partners’ Equity Common Units and General Partner Units At December 31, 2019 there were 33,995,563 common units issued, including 7,402,198 common units held by affiliates of the General Partner, including directors and executive officers, collectively representing a 99.33% limited partner interest in the Partnership, and 230,303 general partner units representing a 0.67% general partner interest in the Partnership. There have been no changes to common units or the general partner interest during the years ended December 31, 2019, 2018 and 2017. Series A Preferred Units On August 7, 2018, the Partnership issued 2,760,000 9.75% Series A Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units representing limited partner interests (the “Series A Preferred Units”) for $25.00 per Series A Preferred Unit. The Partnership used the proceeds, net of underwriting discount and expenses, of $66.4 million to reduce indebtedness under its Credit Agreement. There have been no changes to the Series A Preferred Units during the year ended December 31, 2019. Common Units The common units have limited voting rights as set forth in the Partnership’s partnership agreement. General Partner Units and Incentive Distribution Rights The Partnership’s general partner interest is represented by general partner units. The General Partner is entitled to a percentage (equal to the general partner interest) of all cash distributions of available cash on all common units. The Partnership’s partnership agreement sets forth the calculation to be used to determine the amount and priority of cash distributions that the common unitholders, holders of the incentive distribution rights and the General Partner will receive. The Partnership’s general partner interest has the management rights as set forth in the Partnership’s partnership agreement. Incentive distribution rights represent the right to receive an increasing percentage of quarterly distributions of available cash from distributable cash flow after the target distribution levels have been achieved, as defined in the Partnership’s partnership agreement. The General Partner holds all of the incentive distribution rights, but may transfer these rights separately from its general partner interest, subject to restrictions in the Partnership’s partnership agreement. Series A Preferred Units The Series A Preferred Units is a class of equity security that ranks senior to the common units, the incentive distribution rights and each other class or series of the Partnership’s equity securities established after August 7, 2018, the original issue date of the Series A Preferred Units (the “Original Issue Date”), that is not expressly made senior to or on parity with the Series A Preferred Units as to the payment of distributions and amounts payable on a liquidation event. Allocations of Net Income Net income is allocated between the General Partner and the common unitholders in accordance with the provisions of the Partnership’s partnership agreement. Net income is generally allocated first to the General Partner and the common unitholders in an amount equal to the net losses allocated to the General Partner and the common unitholders in the current and prior tax years under the Partnership’s partnership agreement. The remaining net income is allocated to the General Partner and the common unitholders in accordance with their respective percentage interests of the general partner units and common units. Cash Distributions Common Units The Partnership intends to make cash distributions to common unitholders on a quarterly basis, although there is no assurance as to the future cash distributions since they are dependent upon future earnings, capital requirements, financial condition and other factors. The Credit Agreement prohibits the Partnership from making cash distributions if any potential default or Event of Default, as defined in the Credit Agreement, occurs or would result from the cash distribution. The indentures governing the Partnership’s outstanding senior notes also limit the Partnership’s ability to make distributions to its common unitholders in certain circumstances. Within 45 days after the end of each quarter, the Partnership will distribute all of its Available Cash (as defined in its partnership agreement) to common unitholders of record on the applicable record date. The amount of Available Cash is all cash on hand on the date of determination of Available Cash for the quarter; less the amount of cash reserves established by the General Partner to provide for the proper conduct of the Partnership’s businesses, to comply with applicable law, any of the Partnership’s debt instruments or other agreements or to provide funds for distributions to unitholders and the General Partner for any one or more of the next four quarters. The Partnership will make distributions of Available Cash from distributable cash flow for any quarter in the following manner: 99.33% to the common unitholders, pro rata, and 0.67% to the General Partner, until the Partnership distributes for each outstanding common unit an amount equal to the minimum quarterly distribution for that quarter; and thereafter, cash in excess of the minimum quarterly distribution is distributed to the common unitholders and the General Partner based on the percentages as provided below. As holder of the IDRs, the General Partner is entitled to incentive distributions if the amount that the Partnership distributes with respect to any quarter exceeds specified target levels shown below: Marginal Percentage Total Quarterly Distribution Interest in Distributions Target Amount Unitholders General Partner First Target Distribution up to $0.4625 99.33 % 0.67 % Second Target Distribution above $0.4625 up to $0.5375 86.33 % 13.67 % Third Target Distribution above $0.5375 up to $0.6625 76.33 % 23.67 % Thereafter above $0.6625 51.33 % 48.67 % The Partnership paid the following cash distributions to common unitholders during 2019, 2018 and 2017 (in thousands, except per unit data): Earned for the Per Unit Cash Distribution Quarter Cash Common General Incentive Total Cash Payment Date Ended Distribution Units Partner Distribution Distribution 2017 2/14/2017 12/31/16 $ $ 15,723 $ 106 $ — $ 15,829 5/15/2017 03/31/17 15,723 106 — 15,829 8/14/2017 06/30/17 15,723 106 — 15,829 11/14/2017 09/30/17 15,723 106 — 15,829 2018 2/14/2018 12/31/17 $ $ 15,723 $ 106 $ — $ 15,829 5/15/2018 03/31/18 15,723 106 — 15,829 8/14/2018 (1) 06/30/18 16,149 109 67 16,325 11/14/2018 (1) 09/30/18 16,149 109 67 16,325 2019 2/14/2019 (1) 12/31/18 $ $ 16,998 $ 115 $ 202 $ 17,315 5/15/2019 (1) 03/31/19 17,338 117 256 17,711 8/14/2019 (1) 06/30/19 17,508 118 269 17,895 11/14/2019 (1) 09/30/19 17,678 119 294 18,091 (1) This distribution resulted in the Partnership reaching its second target level distribution for the respective quarter. As a result, the General Partner, as the holder of the IDRs, received an incentive distribution. In addition, on January 27, 2020, the board of directors of the General Partner declared a quarterly cash distribution of $0.5250 per unit ($2.10 per unit on an annualized basis) on all of its outstanding common units for the period from October 1, 2019 through December 31, 2019 to the Partnership’s common unitholders of record as of the close of business February 10, 2020. On February 14, 2020, the Partnership paid the total cash distribution of approximately $18.3 million. Series A Preferred Units Distributions on the Series A Preferred Units are cumulative from the Original Issue Date and payable quarterly in arrears on February 15, May 15, August 15 and November 15 of each year, commencing on November 15, 2018 (each, a “Distribution Payment Date”), to holders of record as of the opening of business on the February 1, May 1, August 1 or November 1 next preceding the Distribution Payment Date, in each case, when, as, and if declared by the General Partner out of legally available funds for such purpose. Distributions on the Series A Preferred Units will be paid out of Available Cash with respect to the quarter immediately preceding the applicable Distribution Payment Date. On November 15, 2018, the Partnership paid the initial quarterly cash distribution of $0.6635 per unit on the Series A Preferred Units, covering the period from the Original Issue Date through November 14, 2018, totaling $1.8 million. The initial distribution rate for the Series A Preferred Units from and including the Original Issue Date, but excluding, August 15, 2023 is 9.75% per annum of the $25.00 liquidation preference per Series A Preferred Unit (equal to $2.4375 per Series A Preferred Unit per annum). On and after August 15, 2023, distributions on the Series A Preferred Units will accumulate for each distribution period at a percentage of the $25.00 liquidation preference equal to an annual floating rate of the three-month LIBOR plus a spread of 6.774% per annum. The Partnership paid the following cash distributions on the Series A Preferred Units during 2019 (in thousands, except per unit data): Earned for the Per Unit Cash Distribution Quarterly Period Cash Total Cash Payment Date Covering Distribution Distribution 2/15/2019 11/15/18 - 2/14/19 $ 0.609375 $ 1,682 5/15/2019 2/15/19 - 5/14/19 0.609375 1,682 8/15/2019 5/15/19 - 8/14/19 0.609375 1,682 11/15/2019 8/15/19 - 11/14/19 0.609375 1,682 In addition, on January 21, 2020, the board of directors of the General Partner declared a quarterly cash distribution of $0.609375 per unit ($2.4375 per unit on an annualized basis) on the Series A Preferred Units for the period from November 15, 2019 through February 14, 2020 to the Partnership’s preferred unitholders of record as of the opening of business on February 3, 2020. On February 18, 2020, the Partnership paid the total cash distribution of approximately $1.7 million.

Business Combinations	Note 20. Business Combinations 2018 Acquisitions Acquisition from Cheshire Oil Company, LLC — On July 24, 2018, the Partnership acquired the assets of ten company-operated gasoline stations and convenience stores from Cheshire in a cash transaction. The portfolio consists of nine stores in New Hampshire and one in Brattleboro, Vermont. All of the locations are branded T-Bird Mini Marts and market Citgo fuel. The purchase price was approximately $33.4 million, including inventory. The acquisition was financed with borrowings under the Partnership’s revolving credit facility. The acquisition was accounted for using the purchase method of accounting in accordance with the FASB’s guidance regarding business combinations. The Partnership’s financial statements include the results of operations of Cheshire subsequent to the acquisition date. In connection with the acquisition of Cheshire, the Partnership incurred acquisition costs of approximately $0.4 million for the year ended December 31, 2018, which are included in selling, general and administrative expenses in the accompanying consolidated statements of operations. Acquisition from Champlain Oil Company, Inc .— On July 17, 2018, the Partnership acquired retail fuel and convenience store assets from Champlain in a cash transaction. The acquisition included 37 company-operated gasoline stations with Jiffy Mart-branded convenience stores in Vermont and New Hampshire and approximately 24 fuel sites that were either owned or leased, including lessee dealer and commission agent locations. The transaction also included fuel supply agreements for approximately 65 gasoline stations, primarily in Vermont and New Hampshire. The stations primarily market major fuel brands such as Mobil, Shell, Citgo, Sunoco and Irving. The purchase price was approximately $138.2 million, including inventory. The acquisition was financed with borrowings under the Partnership’s revolving credit facility. The acquisition was accounted for using the purchase method of accounting in accordance with the FASB’s guidance regarding business combinations. The Partnership’s financial statements include the results of operations of Champlain subsequent to the acquisition date. The following table presents the final allocation of the purchase price to the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition (in thousands): Assets purchased: Inventory $ 5,450 Prepaid expenses and other current assets 270 Property and equipment 112,871 Intangibles 12,936 Total identifiable assets purchased 131,527 Liabilities assumed: Accrued expenses and other current liabilities (131) Environmental liabilities (10,757) Other non-current liabilities (938) Total liabilities assumed (11,826) Net identifiable assets acquired 119,701 Goodwill 18,478 Net assets acquired $ 138,179 The Partnership’s third-party valuation firm considered the income, market and cost approaches in estimating the fair value of the property and equipment and intangible assets. The market and cost approaches were used to value the property and equipment based on the underlying asset class components of the property and equipment. The income approach was used to value the dealer supply contracts, in-place leases and franchise rights. The purchase price for the acquisition was allocated to assets acquired and liabilities assumed based on their estimated fair values. The Partnership then allocated the purchase price in excess of net tangible assets acquired to identifiable intangible assets, based on the valuation from the Partnership’s third-party valuation firm. Any excess purchase price over the fair value of the net tangible and intangible assets acquired was allocated to goodwill and assigned to the GDSO reporting unit. The $18.5 million of goodwill was recognized as the transaction expanded the Partnership’s retail portfolio and geographic footprint in New England and provides additional volume to the Partnership’s terminals in New York and Vermont. The goodwill is expected to be tax deductible. The operations of Champlain have been integrated into the GDSO reporting segment. The fair value of $10.7 million assigned to the assumption of environmental liabilities was developed by management based on their estimates, assumptions and acquisition history. The fair values of the remaining Champlain assets and liabilities noted above approximate their carrying values as of the acquisition date. The Partnership utilized accounting guidance related to intangible assets which lists the pertinent factors to be considered when estimating the useful life of an intangible asset. These factors include, in part, a review of the expected use by the Partnership of the assets acquired, the expected useful life of another asset (or group of assets) related to the acquired assets and legal, regulatory or other contractual provisions that may limit the useful life of an acquired asset. The Partnership amortizes these intangible assets over their estimated useful lives which is consistent with the estimated undiscounted future cash flows of these assets. As part of the purchase price allocation, identifiable intangible assets include dealer supply contracts, in-place leases and franchise rights that are being amortized between one and ten years. Amortization expense related to these intangible assets was $2.3 million and $1.2 million for the years ended December 31, 2019 and 2018, respectively. In connection with the acquisition of Champlain, the Partnership incurred acquisition costs of approximately $3.5 million for the year ended December 31, 2018 which are included in selling, general and administrative expenses in the accompanying consolidated statements of operations. Champlain’s revenues and net income included in the Partnership’s consolidated operating results from July 17, 2018, the acquisition date, through December 31, 2018 were immaterial. 2017 Acquisition Honey Farms, Inc. —On October 18, 2017, the Partnership completed the acquisition of retail gasoline and convenience store assets from Honey Farms in a cash transaction. The acquisition included 11 company-operated retail sites with gasoline and convenience stores and 22 company-operated stand-alone convenience stores. All of the sites are located in and around the greater Worcester, Massachusetts area. The purchase price was approximately $38.5 million, including inventory. The acquisition was financed with borrowings under the Partnership’s revolving credit facility. The acquisition was accounted for using the purchase method of accounting in accordance with the FASB’s guidance regarding business combinations. The Partnership’s financial statements include the results of operations of Honey Farms subsequent to the acquisition date. In connection with the acquisition of Honey Farms, the Partnership incurred acquisition costs of approximately $0.7 million which are included in selling, general and administrative expenses in the accompanying consolidated statements of operations for the year ended December 31, 2017.

Segment Reporting
Segment Reporting	Note 21. Segment Reporting The Partnership engages in the purchasing, selling, gathering, blending, storing and logistics of transporting petroleum and related products, including gasoline and gasoline blendstocks (such as ethanol), distillates (such as home heating oil, diesel and kerosene), residual oil, renewable fuels, crude oil and propane. The Partnership also receives revenue from convenience store sales, rental income and sundries. The Partnership’s three operating segments are based upon the revenue sources for which discrete financial information is reviewed by the chief operating decision maker (the “CODM”) to make key operating decisions and assess performance and include Wholesale, GDSO and Commercial. These operating segments are also the Partnership’s reporting segments. Prior to 2019, the Commercial operating segment has not met the quantitative metrics for disclosure as a reportable segment on a stand‑alone basis as defined in accounting guidance related to segment reporting. However, the Partnership has elected to present segment disclosures for the Commercial operating segment as management believes such disclosures are helpful to the user of the Partnership’s financial information. The accounting policies of the segments are the same as those described in Note 2, “Summary of Significant Accounting Policies.” In the Wholesale reporting segment, the Partnership sells branded and unbranded gasoline and gasoline blendstocks and diesel to wholesale distributors. The Partnership transports these products by railcars, barges, trucks and/or pipelines pursuant to spot or long‑term contracts. From time to time, the Partnership aggregates crude oil by truck or pipeline in the mid-continent region of the United States and Canada, transports it by rail and ships it by barge to refiners. The Partnership sells home heating oil, branded and unbranded gasoline and gasoline blendstocks, diesel, kerosene, residual oil and propane to home heating oil and propane retailers and wholesale distributors. Generally, customers use their own vehicles or contract carriers to take delivery of the gasoline, distillates and propane at bulk terminals and inland storage facilities that the Partnership owns or controls or at which it has throughput or exchange arrangements. Ethanol is shipped primarily by rail and by barge. In the GDSO reporting segment, gasoline distribution includes sales of branded and unbranded gasoline to gasoline station operators and sub jobbers. Station operations include (i) convenience stores, (ii) rental income from gasoline stations leased to dealers, from commissioned agents and from cobranding arrangements and (iii) sundries (such as car wash sales and lottery and ATM commissions). In the Commercial segment, the Partnership includes sales and deliveries to end user customers in the public sector and to large commercial and industrial end users of unbranded gasoline, home heating oil, diesel, kerosene, residual oil and bunker fuel. In the case of public sector commercial and industrial end user customers, the Partnership sells products primarily either through a competitive bidding process or through contracts of various terms. The Partnership responds to publicly issued requests for product proposals and quotes. The Partnership generally arranges for the delivery of the product to the customer’s designated location. The Commercial segment also includes sales of custom blended fuels delivered by barges or from a terminal dock to ships through bunkering activity. An important measure used by the Partnership and the CODM to evaluate segment performance is product margin, which the Partnership defines as product sales minus product costs. Based on the way the business is managed, components of indirect operating costs and corporate expenses are not allocated to the reportable segments. Summarized financial information for the Partnership’s reportable segments for the years ended December 31 is presented in the table below (in thousands): 2019 2018 2017 Wholesale Segment: Sales Gasoline and gasoline blendstocks $ 5,358,550 $ 4,732,028 $ 2,097,811 Crude oil (1) 96,419 109,719 464,234 Other oils and related products (2) 1,974,897 2,049,043 1,725,537 Total $ 7,429,866 $ 6,890,790 $ 4,287,582 Product margin Gasoline and gasoline blendstocks $ 83,982 $ 76,741 $ 82,124 Crude oil (1) (13,047) 7,159 7,279 Other oils and related products (2) 51,584 53,389 62,799 Total $ 122,519 $ 137,289 $ 152,202 Gasoline Distribution and Station Operations Segment: Sales Gasoline $ 3,806,892 $ 4,081,498 $ 3,434,581 Station operations (3) 466,761 427,211 351,876 Total $ 4,273,653 $ 4,508,709 $ 3,786,457 Product margin Gasoline $ 374,550 $ 373,303 $ 326,536 Station operations (3) 225,078 203,098 174,986 Total $ 599,628 $ 576,401 $ 501,522 Commercial Segment: Sales $ 1,378,211 $ 1,273,103 $ 846,513 Product margin $ 28,540 $ 23,611 $ 17,858 Combined sales and Product margin: Sales $ 13,081,730 $ 12,672,602 $ 8,920,552 Product margin (4) $ 750,687 $ 737,301 $ 671,582 Depreciation allocated to cost of sales (87,930) (86,892) (88,530) Combined gross profit $ 662,757 $ 650,409 $ 583,052 (1) Crude oil consists of the Partnership’s crude oil sales and revenue from its logistics activities. (2) Other oils and related products primarily consist of distillates, residual oil and propane. (3) Station operations consist of convenience store sales, rental income and sundries. (4) Product margin is a non-GAAP financial measure used by management and external users of the Partnership’s consolidated financial statements to assess its business. The table above includes a reconciliation of product margin on a combined basis to gross profit, a directly comparable GAAP measure. Approximately 500 million gallons, 500 million gallons and 480 million gallons of the GDSO segment’s sales for the years ended December 31, 2019, 2018 and 2017, respectively, were supplied from petroleum products and renewable fuels sourced by the Wholesale segment. The Commercial segment’s sales were predominantly sourced by the Wholesale segment. These intra-segment sales are not reflected as sales in the Wholesale segment as they are eliminated. None of the Partnership’s customers accounted for greater than 10% of total sales for years ended December 31, 2019, 2018 and 2017. A reconciliation of the totals reported for the reportable segments to the applicable line items in the consolidated financial statements for the years ended December 31 is as follows (in thousands): Year Ended December 31, 2019 2018 2017 Combined gross profit $ 662,757 $ 650,409 $ 583,052 Operating costs and expenses not allocated to operating segments: Selling, general and administrative expenses 170,937 171,002 155,033 Operating expenses 342,382 321,115 283,650 (Gain) loss on trustee taxes — (52,627) 16,194 Lease exit and termination gain (493) (3,506) — Amortization expense 11,431 10,960 9,206 Net (gain) loss on sale and disposition of assets (2,730) 5,880 (1,624) Goodwill and long-lived asset impairment 2,022 414 809 Total operating costs and expenses 523,549 453,238 463,268 Operating income 139,208 197,171 119,784 Interest expense (89,856) (89,145) (86,230) Loss on early extinguishment of debt (13,080) — — Income tax (expense) benefit (1,094) (5,623) 23,563 Net income 35,178 102,403 57,117 Net loss attributable to noncontrolling interest 689 1,502 1,635 Net income attributable to Global Partners LP $ 35,867 $ 103,905 $ 58,752 The Partnership’s foreign assets and foreign sales were immaterial as of and for the years ended December 31, 2019, 2018 and 2017. Segment Assets The Partnership’s terminal assets are allocated to the Wholesale and Commercial segments, and its retail gasoline stations are allocated to the GDSO segment. Due to the commingled nature and uses of the remainder of the Partnership’s assets, it is not reasonably possible for the Partnership to allocate these assets among its reportable segments. The table below presents total assets by reportable segment at December 31, (in thousands): Wholesale Commercial GDSO Unallocated Total December 31, 2019 $ 773,696 $ — $ 1,576,655 $ 458,076 $ 2,808,427 December 31, 2018 $ 615,795 $ — $ 1,415,501 $ 392,995 $ 2,424,291 The increase in total assets from December 31, 2018 is largely due to the adoption of ASC 842 and the associated recording of right of use assets.

Legal Proceedings
Legal Proceedings	Note 23. Legal Proceedings General Although the Partnership may, from time to time, be involved in litigation and claims arising out of its operations in the normal course of business, the Partnership does not believe that it is a party to any litigation that will have a material adverse impact on its financial condition or results of operations. Except as described below and in Note 14 included herein, the Partnership is not aware of any significant legal or governmental proceedings against it or contemplated to be brought against it. The Partnership maintains insurance policies with insurers in amounts and with coverage and deductibles as its general partner believes are reasonable and prudent. However, the Partnership can provide no assurance that this insurance will be adequate to protect it from all material expenses related to potential future claims or that these levels of insurance will be available in the future at economically acceptable prices. Other On January 31, 2020, the Partnership and Global Operating LLC (“Global Operating”) received a notice of arbitration filed against them by the minority members of Basin Transload alleging, among other things, mismanagement by the Partnership and Global Operating of certain business arrangements of Basin Transload. The Partnership and Global Operating deny the allegations set forth in the notice of arbitration and believe they have meritorious defenses to the filing. On February 20, 2020, the Partnership filed a breach of contract claim against the minority members of Basin Transload in the United States District Court of Massachusetts, demanding damages in excess of $5.0 million. The Partnership’s claim arises in connection with the Partnership’s payment in October 2017 of approximately $13.1 million to Tesoro in accordance with the Partnership’s guaranty of a pipeline connection agreement between Basin Transload and Tesoro. In breach of a separate agreement among the Partnership and the minority members, each of the minority members of Basin Transload failed to reimburse the Partnership for 20% of any payments made by the Partnership to Tesoro in connection with the pipeline connection agreement. During the second quarter ended June 30, 2016, the Partnership determined that gasoline loaded from certain loading bays at one of its terminals did not contain the necessary additives as a result of an IT-related configuration error. The error was corrected and all gasoline being sold at the terminal now contains the appropriate additives. Based upon current information, the Partnership believes approximately 14 million gallons of gasoline were impacted. The Partnership has notified the EPA of this error. As a result of this error, the Partnership could be subject to fines, penalties and other related claims, including customer claims. On August 2, 2016, the Partnership received a Notice of Violation (“NOV”) from the EPA, alleging that permits for the Partnership’s petroleum product transloading facility in Albany, New York (the “Albany Terminal”), issued by the New York State Department of Environmental Conservation (“NYSDEC”) between August 9, 2011 and November 7, 2012, violated the Clean Air Act (the “CAA”) and the federally enforceable New York State Implementation Plan (“SIP”) by increasing throughput of crude oil at the Albany Terminal without complying with the New Source Review (“NSR”) requirements of the SIP. The Albany Terminal is a 63-acre licensed, permitted and operational stationary bulk petroleum storage and transfer terminal that currently consists of petroleum product storage tanks, along with truck, rail and marine loading facilities, for the storage, blending and distribution of various petroleum and related products, including gasoline, ethanol, distillates, heating and crude oils. The applicable permits issued by the NYSDEC to the Partnership in 2011 and 2012 specifically authorize the Partnership to increase the throughput of crude oil at the Albany Terminal. According to the allegations in the NOV, the NYSDEC permit actions should have been treated as a major modification under the NSR program, requiring additional emission control measures and compliance with other NSR requirements. The NYSDEC has not alleged that the Partnership’s permits were subject to the NSR program and the NYSDEC never issued an NOV in the matter. The CAA authorizes the EPA to take enforcement action in response to violations of the New York SIP seeking compliance and penalties. The Partnership believes that the permits issued by the NYSDEC comply with the CAA and applicable state air permitting requirements and that no material violation of law has occurred. The Partnership disputed the claims alleged in the NOV and first responded to the EPA in September 2016. The Partnership met with the EPA and provided additional information at the agency’s request. On December 16, 2016, the EPA proposed a Settlement Agreement in a letter to the Partnership relating to the allegations in the NOV. On January 17, 2017, the Partnership responded to the EPA indicating that the EPA had failed to explain or provide support for its allegations and that the EPA needed to better explain its positions and the evidence on which it was relying. The EPA did not respond with such evidence, but instead has requested that the Partnership enter into a series of tolling agreements. The Partnership has signed the tolling agreements with respect to this matter, as requested by the EPA, and such agreements currently extend through June 30, 2020. To date, the EPA has not taken any further formal action with respect to the NOV. By letter dated January 25, 2017, the Partnership received a notice of intent to sue (the “2017 NOI”) from Earthjustice related to alleged violations of the CAA; specifically alleging that the Partnership was operating the Albany Terminal without a valid CAA Title V Permit. On February 9, 2017, the Partnership responded to Earthjustice advising that the 2017 NOI was without factual or legal merit and that the Partnership would move to dismiss any action commenced by Earthjustice. No action was taken by either the EPA or the NYSDEC with regard to the Earthjustice allegations. At this time, there has been no further action taken by Earthjustice. Neither the EPA nor the NYSDEC has followed up on the 2017 NOI. The Albany Terminal is currently operating pursuant to its Title V Permit, which has been extended in accordance with the State Administrative Procedures Act. The Partnership believes that it has meritorious defenses against all allegations. On March 26, 2015, the Partnership received a Notice of Non-Compliance (“NON”) from the Massachusetts Department of Environmental Protection (“DEP”) with respect to the Revere terminal (the “Revere Terminal”) located in Boston Harbor in Revere, Massachusetts, alleging certain violations of the National Pollutant Discharge Elimination System Permit (“NPDES Permit”) related to storm water discharges. The NON required the Partnership to submit a plan to remedy the reported violations of the NPDES Permit. The Partnership has responded to the NON with a plan and has implemented modifications to the storm water management system at the Revere Terminal in accordance with the plan. The Partnership has requested that the DEP acknowledge completion of the required modifications to the storm water management system in satisfaction of the NON. While no response has yet been received, the Partnership believes that compliance with the NON has been achieved, and implementation of the plan will have no material impact on its operations. The Partnership received letters from the EPA dated November 2, 2011 and March 29, 2012, containing requirements and testing orders (collectively, the “Requests for Information”) for information under the CAA. The Requests for Information were part of an EPA investigation to determine whether the Partnership has violated sections of the CAA at certain of its terminal locations in New England with respect to residual oil and asphalt. On June 6, 2014, a NOV was received from the EPA, alleging certain violations of its Air Emissions License issued by the Maine Department of Environmental Protection, based upon the test results at the South Portland, Maine terminal. The Partnership met with and provided additional information to the EPA with respect to the alleged violations. On April 7, 2015, the EPA issued a Supplemental Notice of Violation modifying the allegations of violations of the terminal’s Air Emissions License. The Partnership has entered into a consent decree (the “Consent Decree”) with the EPA and the United States Department of Justice (the “Department of Justice”), which was filed in the U.S. District Court for the District of Maine (the “Court”) on March

Summary of Significant Accounting Policies
Basis of Consolidation and Presentation	Basis of Consolidation and Presentation On July 24, 2018, the Partnership acquired the assets of company-operated gasoline stations and convenience stores from New Hampshire-based Cheshire Oil Company, LLC (“Cheshire”). On July 17, 2018, the Partnership acquired retail fuel and convenience store assets from Vermont-based Champlain Oil Company, Inc. (“Champlain”). On October 18, 2017, the Partnership acquired retail gasoline and convenience store assets from Honey Farms, Inc. (“Honey Farms”). The financial results of Cheshire, Champlain and Honey Farms since the respective acquisition date are included in the accompanying consolidated statements of operations. See Note 20, “Business Combinations,” for additional information on the Partnership’s acquisitions. The accompanying consolidated financial statements as of December 31, 2019 and 2018 and for the years ended December 31, 2019, 2018 and 2017 reflect the accounts of the Partnership. Upon consolidation, all intercompany balances and transactions have been eliminated.
Noncontrolling Interest	Noncontrolling Interest These financial statements reflect the application of Accounting Standards Codification (“ASC”) Topic 810, “Consolidations” (“ASC 810”) which establishes accounting and reporting standards that require: (i) the ownership interest in subsidiaries held by parties other than the parent to be clearly identified and presented in the consolidated balance sheet within shareholder’s equity, but separate from the parent’s equity, (ii) the amount of consolidated net income attributable to the parent and the noncontrolling interest to be clearly identified and presented on the face of the consolidated statements of operations, and (iii) changes in a parent’s ownership interest while the parent retains its controlling financial interest in its subsidiary to be accounted for consistently. The Partnership acquired a 60% interest in Basin Transload LLC (“Basin Transload”) on February 1, 2013. After evaluating ASC 810, the Partnership concluded it is appropriate to consolidate the balance sheet and statements of operations of Basin Transload based on an evaluation of the outstanding voting interests. Amounts pertaining to the noncontrolling ownership interest held by third parties in the financial position and operating results of the Partnership are reported as a noncontrolling interest in the accompanying consolidated balance sheets and statements of operations.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates under different assumptions or conditions. Among the estimates made by management are (i) estimated fair value of assets and liabilities acquired in a business combination and identification of associated goodwill and intangible assets, (ii) fair value of derivative instruments, (iii) accruals and contingent liabilities, (iv) allowance for doubtful accounts, (v) assumptions used to evaluate goodwill, property and equipment and intangibles for impairment, (vi) environmental and asset retirement obligation provisions, (vii) cost of sales accrual, and (viii) weighted average discount rate used in lease accounting. Although the Partnership believes these estimates are reasonable, actual results could differ from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents The Partnership considers highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. The carrying value of cash and cash equivalents, including broker margin accounts, approximates fair value.
Accounts Receivable	Accounts Receivable The Partnership’s accounts receivable primarily results from sales of refined petroleum products, gasoline blendstocks, renewable fuels, crude oil and propane to its customers. The majority of the Partnership’s accounts receivable relates to its petroleum marketing activities that can generally be described as high volume and low margin activities. The Partnership makes a determination of the amount, if any, of a line of credit it may extend to a customer based on the form and amount of financial performance assurances the Partnership requires. Such financial assurances are commonly provided to the Partnership in the form of standby letters of credit, personal guarantees or corporate guarantees. The Partnership reviews all accounts receivable balances on a monthly basis and records a reserve for estimated amounts it expects will not be fully recovered. At December 31, 2019 and 2018, substantially all of the Partnership’s accounts receivable were classified as current assets and there were no non-standard payment terms.
Inventories	Inventories The Partnership hedges substantially all of its petroleum and ethanol inventory using a variety of instruments, primarily exchange-traded futures contracts. These futures contracts are entered into when inventory is purchased and are either designated as fair value hedges against the inventory on a specific barrel basis for inventories qualifying for fair value hedge accounting or not designated and maintained as economic hedges against certain inventory of the Partnership on a specific barrel basis. Changes in fair value of these futures contracts, as well as the offsetting change in fair value on the hedged inventory, are recognized in earnings as an increase or decrease in cost of sales. All hedged inventory designated in a fair value hedge relationship is valued using the lower of cost, as determined by specific identification, or net realizable value, as determined at the product level. All petroleum and ethanol inventory not designated in a fair value hedging relationship is carried at the lower of historical cost, on a first-in, first-out basis, or net realizable value. Renewable Identification Numbers (“RINs”) inventory is carried at the lower of historical cost, on a first-in, first-out basis, or net realizable value. Convenience store inventory is carried at the lower of historical cost, based on a weighted average cost method, or net realizable value. Inventories consisted of the following at December 31 (in thousands): 2019 2018 Distillates: home heating oil, diesel and kerosene $ 222,202 $ 173,403 Gasoline 120,958 93,534 Gasoline blendstocks 39,702 52,195 Crude oil 16,018 21,325 Residual oil 26,521 21,054 Propane and other 1,356 1,447 Renewable identification numbers (RINs) 1,329 1,034 Convenience store inventory 22,396 22,450 Total $ 450,482 $ 386,442 In addition to its own inventory, the Partnership has exchange agreements for petroleum products and ethanol with unrelated third‑party suppliers, whereby it may draw inventory from these other suppliers (see Revenue Recognition ) and suppliers may draw inventory from the Partnership. Positive exchange balances are accounted for as accounts receivable and amounted to $9.2 million and $3.8 million at December 31, 2019 and 2018, respectively. Negative exchange balances are accounted for as accounts payable and amounted to $17.6 million and $14.9 million at December 31, 2019 and 2018, respectively. Exchange transactions are valued using current carrying costs.
Property and Equipment	Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Minor expenditures for routine maintenance, repairs and renewals are charged to expense as incurred, and major improvements that extend the useful lives of the related assets are capitalized. Depreciation related to the Partnership’s terminal assets and gasoline stations is charged to cost of sales and all other depreciation is charged to selling, general and administrative expenses. Depreciation is charged over the estimated useful lives of the applicable assets using straight‑line methods, and accelerated methods are used for income tax purposes. When applicable and based on policy, which considers the construction period and project cost, the Partnership capitalizes interest on qualified long‑term projects and depreciates it over the life of the related asset. The estimated useful lives are as follows: Gasoline station buildings, improvements and storage tanks 15-25 years Buildings, docks, terminal facilities and improvements 5-25 years Gasoline station equipment 7 years Fixtures, equipment and capitalized internal use software 3-7 years The Partnership capitalizes certain costs, including internal payroll and external direct project costs incurred in connection with developing or obtaining software designated for internal use. These costs are included in property and equipment and are amortized over the estimated useful lives of the related software.
Intangibles	Intangibles Intangibles are carried at cost less accumulated amortization. For assets with determinable useful lives, amortization is computed over the estimated economic useful lives of the respective intangible assets, ranging from 3 to 20 years.
Goodwill and Long-Lived Asset Impairment	Goodwill and Long-Lived Asset Impairment Goodwill Goodwill represents the future economic benefits arising from assets acquired in a business combination that are not individually identified and separately recognized. The Partnership has concluded that its operating segments are also its reporting units. Goodwill is tested for impairment annually as of October 1 or when events or changes in circumstances indicate that the carrying amount of goodwill may not be recoverable. Derecognized goodwill associated with the Partnership’s disposition activities of Gasoline Distribution and Station Operation (“GDSO”) sites is included in the carrying value of assets sold in determining the gain or loss on disposal, to the extent the disposition of assets qualifies as a disposition of a business under ASC 805. The GDSO reporting unit’s goodwill that was derecognized related to the disposition of sites that met the definition of a business was $2.9 million, $3.9 million and $4.0 million for the years ended December 31, 2019, 2018 and 2017, respectively (see Note 7). All of the Partnership’s goodwill is allocated to the GDSO segment. During 2019, 2018 and 2017, the Partnership completed a quantitative assessment for the GDSO reporting unit. Factors included in the assessment included both macro‑economic conditions and industry specific conditions, and the fair value of the GDSO reporting unit was estimated using a weighted average of a discounted cash flow approach and a market comparables approach. Based on the Partnership’s assessment, no impairment was identified. Evaluation of Long-Lived Asset Impairment Accounting and reporting guidance for long‑lived assets requires that a long‑lived asset (group) be reviewed for impairment when events or changes in circumstances indicate that the carrying amount might not be recoverable. Accordingly, the Partnership evaluates long-lived assets for impairment whenever indicators of impairment are identified. If indicators of impairment are present, the Partnership assesses impairment by comparing the undiscounted projected future cash flows from the long‑lived assets to their carrying value. If the undiscounted cash flows are less than the carrying value, the long‑lived assets will be reduced to their fair value. The Partnership recognized an impairment charge of $2.0 million, $0.4 million and $0.8 million for the years ended December 31, 2019, 2018 and 2017, respectively, relating to long-lived assets at certain gasoline stations and convenience stores. These assets are allocated to the GDSO segment, and the respective impairment is included in goodwill and long-lived asset impairment in the accompanying consolidated statements of operations for the years ended December 31, 2019, 2018 and 2017.
Environmental and Other Liabilities	Environmental and Other Liabilities The Partnership accrues for all direct costs associated with the estimated resolution of contingencies at the earliest date at which it is deemed probable that a liability has been incurred and the amount of such liability can be reasonably estimated. Costs accrued are estimated based upon an analysis of potential results, assuming a combination of litigation and settlement strategies and outcomes. Estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study. Loss accruals are adjusted as further information becomes available or circumstances change. Costs of future expenditures for environmental remediation obligations are not discounted to their present value. Recoveries of environmental remediation costs from other parties are recognized when related contingencies are resolved, generally upon cash receipt. The Partnership is subject to other contingencies, including legal proceedings and claims arising out of its businesses that cover a wide range of matters, including environmental matters and contract and employment claims. Environmental and other legal proceedings may also include matters with respect to businesses previously owned. Further, due to the lack of adequate information and the potential impact of present regulations and any future regulations, there are certain circumstances in which no range of potential exposure may be reasonably estimated. See Notes 14 and 23. .
Asset Retirement Obligations	Asset Retirement Obligations The Partnership is required to account for the legal obligations associated with the long‑lived assets that result from the acquisition, construction, development or operation of long‑lived assets. Such asset retirement obligations specifically pertain to the treatment of underground gasoline storage tanks (“USTs”) that exist in those states which statutorily require removal of the USTs at a certain point in time. Specifically, the Partnership’s retirement obligations consist of the estimated costs of removal and disposals of USTs. The liability for an asset retirement obligation is recognized on a discounted basis in the year in which it is incurred, and the discount period applied is based on statutory requirements for UST removal or policy. The associated asset retirement costs are capitalized as part of the carrying cost of the asset. The Partnership had approximately $8.0 million and $8.8 million in total asset retirement obligations at December 31, 2019 and 2018, respectively, which are included in other long‑term liabilities in the accompanying consolidated balance sheets.
Leases	Leases The Partnership has gasoline station and convenience store leases, primarily of land and buildings. The Partnership has terminal and dedicated storage facility lease arrangements with various petroleum terminals and third parties, of which certain arrangements have minimum usage requirements. The Partnership leases barges through various time charter lease arrangements and railcars through various lease arrangements. The Partnership also has leases for office space, computer and convenience store equipment and automobiles. The Partnership’s lease arrangements have various expiration dates with options to extend. The Partnership is also the lessor party to various lease arrangements with various expiration dates, including the leasing of gasoline stations and certain equipment to third-party station operators and cobranding lease agreements for certain space within the Partnership’s gasoline stations and convenience stores. In addition, the Partnership is party to three master unitary lease agreements in connection with (i) the June 2015 acquisition of retail gasoline stations from Capitol Petroleum Group (“Capitol”) related to properties previously sold by Capitol within two sale-leaseback transactions; and (ii) the June 2016 sale of real property assets at 30 gasoline stations and convenience stores that did not meet the criteria for sale accounting. These transactions continue to be accounted for as financing obligations (see Note 8) upon transition to ASC 842, “Leases,” which the Partnership adopted on January 1, 2019. Accounting and reporting guidance for leases requires that leases be evaluated and classified as either operating or finance leases by the lessee and as either operating, sales-type or direct financing leases by the lessor. The Partnership’s operating leases are included in right-of-use (“ROU”) assets, lease liability-current portion and long-term lease liability-less current portion in the accompanying consolidated balance sheets. ROU assets represent the Partnership’s right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Partnership’s variable lease payments consist of payments that depend on an index or rate (such as the Consumer Price Index) as well as those payments that depend on the Partnership’s performance or use of the underlying asset related to the lease. Variable lease payments are excluded from the ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. As most of the Partnership’s leases do not provide an implicit rate in determining the net present value of lease payments, the Partnership uses its incremental borrowing rate based on the information available at the lease commencement date. ROU assets also include any lease payments made and exclude lease incentives. Many of the Partnership’s lessee agreements include options to extend the lease, which are not included in the minimum lease terms unless they are reasonably certain to be exercised. Rental expense for lease payments related to operating leases is recognized on a straight-line basis over the lease term. Rental income for lease payments received related to operating leases is recognized on a straight-line basis over the lease term. The Partnership has elected the package of practical expedients permitted under the transition guidance within the new standard which, among other things, allows the Partnership to carry forward the historical accounting relating to lease identification and classification for existing leases upon adoption. Leases with an initial term of 12 months or less are not recorded on the balance sheet as the Partnership recognizes lease expense for these leases on a straight-line basis over the lease term. The Partnership’s leases have contracted terms as follows: Gasoline station and convenience store leases 1-20 years Terminal lease arrangements 1-5 years Dedicated storage facility leases 1-5 years Barge and railcar equipment leases 1-10 years Office space leases 1-12 years Computer equipment, convenience store equipment and automobile leases 1-5 years The above table excludes the Partnership’s West Coast facility land lease arrangement which contract term is subject to expiration through July 2066. Some of the above leases include options to extend the leases for up to an additional 30 years. The Partnership does not include renewal options in its lease terms for calculating the lease liability unless the Partnership is reasonably certain the renewal options are to be exercised. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Lease Exit Termination Gain In December 2016, the Partnership voluntarily terminated early a sublease with a counterparty for 1,610 railcars that were underutilized due to unfavorable market conditions in the crude oil by rail market. Separately, the Partnership entered into a fleet management services agreement (effective January 1, 2017) (the “Services Agreement”) with the counterparty, pursuant to which the Partnership would provide railcar storage, freight, insurance and other services on behalf of the counterparty. During each of 2019 and 2018, the Partnership was released from certain of its obligations under the Services Agreement, which resulted in a reduction of the remaining accrued incremental costs of $0.5 million and $3.5 million for the years ended December 31, 2019 and 2018, respectively, which benefit is included in lease exit and termination gain in the accompanying statements of operations. The remaining accrued incremental costs were $1.3 million at December 31, 2019.
Revenue Recognition	Revenue Recognition The Partnership’s sales relate primarily to the sale of refined petroleum products, gasoline blendstocks, renewable fuels, crude oil and propane and are recognized along with the related receivable upon delivery, net of applicable provisions for discounts and allowances. The Partnership may also provide for shipping costs at the time of sale, which are included in cost of sales. Contracts with customers typically contain pricing provisions that are tied to a market index, with certain adjustments based on quality and freight due to location differences and prevailing supply and demand conditions, as well as other factors. As a result, the price of the products fluctuates to remain competitive with other available product supplies. The revenue associated with such arrangements is recognized upon delivery. In addition, the Partnership generates revenue from its logistics activities when it stores, transloads and ships products owned by others. Revenue from logistics services is recognized as services are provided. Logistics agreements may require counterparties to throughput a minimum volume over an agreed-upon period and may include make-up rights if the minimum volume is not met. The Partnership recognizes revenue associated with make-up rights at the earlier of when the make-up volume is shipped, the make-up right expires or when it is determined that the likelihood that the shipper will utilize the make-up right is remote. The Partnership also recognizes convenience store sales of gasoline, grocery and other merchandise and sundries at the time of the sale to the customer. Gasoline station rental income is recognized on a straight‑line basis over the term of the lease. Product revenue is not recognized on exchange agreements, which are entered into primarily to acquire various refined petroleum products, gasoline blendstocks, renewable fuels and crude oil of a desired quality or to reduce transportation costs by taking delivery of products closer to the Partnership’s end markets. The Partnership recognizes net exchange differentials due from exchange partners in sales upon delivery of product to an exchange partner. The Partnership recognizes net exchange differentials due to exchange partners in cost of sales upon receipt of product from an exchange partner. The amounts recorded for bad debts are 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.
Trustee Taxes	Trustee Taxes The Partnership collects trustee taxes, which consist of various pass through taxes collected on behalf of taxing authorities, and remits such taxes directly to those taxing authorities. Examples of trustee taxes include, among other things, motor fuel excise tax and sales and use tax. As such, it is the Partnership’s policy to exclude trustee taxes from revenues and cost of sales and account for them as current liabilities. See Note 12 for additional information. The Partnership may be subject to audits of its state and federal tax returns prepared for trustee taxes. Historically, any tax adjustments from such audits have been deemed immaterial by the Partnership and have been included in cost of sales. In November of 2017, the Partnership received an assessment from a state taxing authority in connection with its audit of the Partnership’s fuel and sales tax returns for the periods from December 2008 through August 2013 (the “Audit”). In February of 2018, the Partnership agreed to administratively close the Audit, and, as a result, recognized a loss on trustee taxes of $16.2 million during the fourth quarter of 2017, which is included in (gain) loss on trustee taxes in the accompanying consolidated statements of operations for the year ended December 31, 2017. The loss on trustee taxes consists of both tax and interest, with no penalties being assessed. Although the Audit has been administratively closed, the Partnership has the right to seek recovery of the payment of the trustee tax. While the Partnership believes it has meritorious arguments and defenses to recover a majority of the tax and interest assessed, the Partnership cannot be certain of such outcome. Volumetric Ethanol Excise Tax Credit— In the first quarter of 2018, the Partnership recognized a one-time income item of approximately $52.6 million as a result of the extinguishment of a contingent liability related to the Volumetric Ethanol Excise Tax Credit, which tax credit program expired in 2011. Based upon the significant passage of time from that 2011 expiration date, including underlying statutes of limitation, as of January 31, 2018 the Partnership determined that the liability was no longer required. The liability had historically been included in trustee taxes in the accompanying consolidated balance sheets. The recognition of this one-time income item, which is included in (gain) loss on trustee taxes in the accompanying consolidated statements of operations for the year ended December 31, 2018, did not impact cash flows from operations for the year ended December 31, 2018.
Income Taxes	Income Taxes Section 7704 of the Internal Revenue Code provides that publicly‑traded partnerships are, as a general rule, taxed as corporations. However, an exception, referred to as the “Qualifying Income Exception,” exists under Section 7704(c) with respect to publicly‑traded partnerships of which 90% or more of the gross income for every taxable year consists of “qualifying income.” Qualifying income includes income and gains derived from the transportation, storage and marketing of refined petroleum products, gasoline blendstocks, crude oil and ethanol to resellers and refiners. Other types of qualifying income include interest (other than from a financial business), dividends, gains from the sale of real property and gains from the sale or other disposition of capital assets held for the production of income that otherwise constitutes qualifying income. Substantially all of the Partnership’s income is “qualifying income” for federal income tax purposes and, therefore, is not subject to federal income taxes at the partnership level. Accordingly, no provision has been made for income taxes on the qualifying income in the Partnership’s financial statements. Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under the Partnership’s agreement of limited partnership. Individual unitholders have different investment basis depending upon the timing and price at which they acquired their common units. Further, each unitholder’s tax accounting, which is partially dependent upon the unitholder’s tax position, differs from the accounting followed in the Partnership’s consolidated financial statements. Accordingly, the aggregate difference in the basis of the Partnership’s net assets for financial and tax reporting purposes cannot be readily determined because information regarding each unitholder’s tax attributes in the Partnership is not available to the Partnership. One of the Partnership’s wholly owned subsidiaries, GMG, is a taxable entity for federal and state income tax purposes. Current and deferred income taxes are recognized on the separate earnings of GMG. The after‑tax earnings of GMG are included in the earnings of the Partnership. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes for GMG. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Partnership calculates its current and deferred tax provision based on estimates and assumptions that could differ from actual results reflected in income tax returns filed in subsequent years. Adjustments based on filed returns are recorded when identified. See Note 13.
Concentration of Risk	Concentration of Risk Financial instruments that potentially subject the Partnership to concentration of credit risk consist primarily of cash, cash equivalents, accounts receivable, firm commitments and, under certain circumstances, futures contracts, forward fixed price contracts, options and swap agreements which may be used to hedge commodity and interest rate risks. The Partnership provides credit in the normal course of its business. The Partnership performs ongoing credit evaluations of its customers and provides for credit losses based on specific information and historical trends. Credit risk on trade receivables is minimized as a result of the Partnership’s large customer base. Losses have historically been within management’s expectations. See Note 9 for a discussion regarding risk of credit loss related to futures contracts, forward fixed price contracts, options and swap agreements. The Partnership’s wholesale and commercial customers of refined petroleum products, gasoline blendstocks, renewable fuels, crude oil and propane are located primarily in the Northeast. The Partnership’s retail gasoline stations and directly operated convenience stores are also located primarily in the Northeast. Due to the nature of the Partnership’s businesses and its reliance, in part, on consumer travel and spending patterns, the Partnership may experience more demand for gasoline during the late spring and summer months than during the fall and winter. Travel and recreational activities are typically higher in these months in the geographic areas in which the Partnership operates, increasing the demand for gasoline. Therefore, the Partnership’s volumes in gasoline are typically higher in the second and third quarters of the calendar year. As demand for some of the Partnership’s refined petroleum products, specifically home heating oil and residual oil for space heating purposes, is generally greater during the winter months, heating oil and residual oil volumes are generally higher during the first and fourth quarters of the calendar year. These factors may result in fluctuations in the Partnership’s quarterly operating results. The following table presents the Partnership’s product sales and other revenues as a percentage of the consolidated sales for the years ended December 31: 2019 2018 2017 Gasoline sales: gasoline and gasoline blendstocks (such as ethanol) 75 % 74 % 65 % Distillates (home heating oil, diesel and kerosene), residual oil and propane sales 21 % 22 % 26 % Crude oil sales and crude oil logistics revenue 1 % 1 % 5 % Convenience store sales, rental income and sundries 3 % 3 % 4 % Total 100 % 100 % 100 % The following table presents the Partnership’s product margin (product sales minus product costs) by segment as a percentage of the consolidated product margin for the years ended December 31: 2019 2018 2017 Wholesale segment 16 % 19 % 23 % Gasoline Distribution and Station Operations segment 80 % 78 % 74 % Commercial segment 4 % 3 % 3 % Total 100 % 100 % 100 % See Note 21, “Segment Reporting,” for additional information on the Partnership’s operating segments. The Partnership is dependent on a number of suppliers of fuel‑related products, both domestically and internationally. The Partnership is dependent on the suppliers being able to source product on a timely basis and at favorable pricing terms. The loss of certain principal suppliers or a significant reduction in product availability from principal suppliers could have a material adverse effect on the Partnership, at least in the near term. The Partnership believes that its relationships with its suppliers are satisfactory and that the loss of any principal supplier could be replaced by new or existing suppliers.
Derivative Financial Instruments	Derivative Financial Instruments The Partnership principally uses derivative instruments, which include regulated exchange-traded futures and options contracts (collectively, “exchange-traded derivatives”) and physical and financial forwards and over-the counter (“OTC”) swaps (collectively, “OTC derivatives”), to reduce its exposure to unfavorable changes in commodity market prices and interest rates. The Partnership uses these exchange-traded and OTC derivatives to hedge commodity price risk associated with its inventory and undelivered forward commodity purchases and sales (“physical forward contracts”). The Partnership accounts for derivative transactions in accordance with ASC Topic 815, “Derivatives and Hedging,” and recognizes derivatives instruments as either assets or liabilities in the consolidated balance sheet and measures those instruments at fair value. The changes in fair value of the derivative transactions are presented currently in earnings, unless specific hedge accounting criteria are met. The fair value of exchange-traded derivative transactions reflects amounts that would be received from or paid to the Partnership’s brokers upon liquidation of these contracts. The fair value of these exchange-traded derivative transactions is presented on a net basis, offset by the cash balances on deposit with the Partnership’s brokers, presented as brokerage margin deposits in the consolidated balance sheets. The fair value of OTC derivative transactions reflects amounts that would be received from or paid to a third party upon liquidation of these contracts under current market conditions. The fair value of these OTC derivative transactions is presented on a gross basis as derivative assets or derivative liabilities in the consolidated balance sheets, unless a legal right of offset exists. The presentation of the change in fair value of the Partnership’s exchange-traded derivatives and OTC derivative transactions depends on the intended use of the derivative and the resulting designation. Derivatives Accounted for as Hedges – The Partnership utilizes fair value hedges to hedge commodity price risk and interest rate risk. Derivatives designated as fair value hedges are used to hedge price risk in commodity inventories and principally include exchange-traded futures contracts that are entered into in the ordinary course of business. For a derivative instrument designated as a fair value hedge, the gain or loss is recognized in earnings in the period of change together with the offsetting change in fair value on the hedged item of the risk being hedged. Gains and losses related to fair value hedges are recognized in the consolidated statements of operations through cost of sales. These futures contracts are settled on a daily basis by the Partnership through brokerage margin accounts.
Derivatives Not Accounted for as Hedges	Derivatives Not Accounted for as Hedges – The Partnership utilizes petroleum and ethanol commodity contracts and foreign currency derivatives to hedge price and currency risk in certain commodity inventories and physical forward contracts. Petroleum and Ethanol Commodity Contracts The Partnership uses exchange-traded derivative contracts to hedge price risk in certain commodity inventories which do not qualify for fair value hedge accounting or are not designated by the Partnership as fair value hedges. Additionally, the Partnership uses exchange-traded derivative contracts, and occasionally financial forward and OTC swap agreements, to hedge commodity price exposure associated with its physical forward contracts which are not designated by the Partnership as cash flow hedges. These physical forward contracts, to the extent they meet the definition of a derivative, are considered OTC physical forwards and are reflected as derivative assets or derivative liabilities in the consolidated balance sheet. The related exchange-traded derivative contracts (and financial forward and OTC swaps, if applicable) are also reflected as brokerage margin deposits (and derivative assets or derivative liabilities, if applicable) in the consolidated balance sheet, thereby creating an economic hedge. Changes in fair value of these derivative instruments are recognized in the consolidated statement of operations through cost of sales. These exchange-traded derivatives are settled on a daily basis by the Partnership through brokerage margin accounts. While the Partnership seeks to maintain a position that is substantially balanced within its commodity product purchase and sale activities, it may experience net unbalanced positions for short periods of time as a result of variances in daily purchases and sales and transportation and delivery schedules as well as other logistical issues inherent in the businesses, such as weather conditions. In connection with managing these positions, the Partnership is aided by maintaining a constant presence in the marketplace. The Partnership also engages in a controlled trading program for up to an aggregate of 250,000 barrels of commodity products at any one point in time. Changes in fair value of these derivative instruments are recognized in the consolidated statement of operations through cost of sales. Foreign Currency Contracts The Partnership may use forward foreign currency contracts to hedge certain foreign denominated (Canadian) commodity product purchases. These forward foreign currency contracts are not designated by the Partnership as hedges and are reflected as prepaid expenses and other current assets or accrued expenses and other current liabilities in the consolidated balance sheets. Changes in fair values of these forward foreign currency contracts are reflected in cost of sales. Margin Deposits All of the Partnership’s exchange-traded derivative contracts (designated and not designated) are transacted through clearing brokers. The Partnership deposits initial margin with the clearing brokers, along with variation margin, which is paid or received on a daily basis, based upon the changes in fair value of open futures contracts and settlement of closed futures contracts. Cash balances on deposit with clearing brokers and open equity are presented on a net basis within brokerage margin deposits in the consolidated balance sheets. See Note 9, “Derivative Financial Instruments,” for additional information.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The Partnership utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. The Partnership primarily applies the market approach for recurring fair value measurements and endeavors to utilize the best available information. Accordingly, the Partnership utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The Partnership is able to classify fair value balances based on the observability of those inputs. The fair value hierarchy that prioritizes the inputs used to measure fair value, giving the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). At each balance sheet reporting date, the Partnership categorizes its financial assets and liabilities using the three levels of the fair value hierarchy defined as follows: Level 1 —Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 primarily consists of financial instruments such as the Partnership’s exchange-traded derivative instruments and pension plan assets. Level 2 —Quoted prices in active markets are not available; however, pricing inputs are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. Level 2 primarily consists of non-exchange-traded derivatives such as OTC derivatives. Level 3 —Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value. Level 3 includes certain OTC forward derivative instruments related to crude oil and propane. Please see Note 10, “Fair Value Measurements,” for additional information.
Net Income Per Limited Partner Unit	Net Income Per Limited Partner Unit Under the Partnership’s partnership agreement, for any quarterly period, the incentive distribution rights (“IDRs”) participate in net income only to the extent of the amount of cash distributions actually declared, thereby excluding the IDRs from participating in the Partnership’s undistributed net income or losses. Accordingly, the Partnership’s undistributed net income or losses is assumed to be allocated to the common unitholders and to the General Partner’s general partner interest. Common units outstanding as reported in the accompanying consolidated financial statements at December 31, 2019 and 2018 excludes 128,170 and 244,128 common units, respectively, held on behalf of the Partnership pursuant to its repurchase program ( see Note 17). These units are not deemed outstanding for purposes of calculating net income per common limited partner unit (basic and diluted).

Accounting Standards or Updates Recently Adopted or Not Yet Effective	Accounting Standards or Updates Recently Adopted In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities.” This standard expands and refines hedge accounting for both financial and non-financial risk components, aligns the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The Partnership adopted this standard on January 1, 2019 with no material impact on the Partnership’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases,” and has modified the standard thereafter through a series of amendments, now codified as ASC 842. ASC 842 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting, however lessor accounting under the new standard is substantially unchanged. The Partnership adopted this standard on January 1, 2019 using a prospective transition approach, which applies the provisions of the new guidance at the effective date without adjusting the comparative periods presented. The Partnership has elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the Partnership to carry forward the historical accounting relating to lease identification and classification for existing leases upon adoption. The Partnership made an accounting policy election to keep leases with an initial term of 12 months or less off of the consolidated balance sheet. The Partnership has conducted analyses, conducted detailed contract reviews, considered expanded disclosure requirements, assessed internal control impacts and implemented a new lease accounting system as part of evaluating the impacts of ASU 2016-02 and adopting the accounting guidance. See above for the Partnership’s policy on leases and Note 3 for the required disclosures under ASC 842. Accounting Standards or Updates Not Yet Effective In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This standard aligns the requirements for capitalizing implementation costs in a cloud computing arrangement with the requirements for capitalizing implementation costs incurred for an internal-use software license. This standard is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. This guidance may be adopted either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Partnership is assessing the impact this standard will have on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Changes to the Disclosure Requirements for Fair Value Measurement,” which amends existing guidance on disclosure requirements for fair value measurements. This standard requires prospective application on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty. The effects of other amendments must be applied retrospectively to all periods presented. This standard is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted. The Partnership is assessing the impact this standard will have on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.” This standard requires that for most financial assets, losses be based on an expected loss approach which includes estimates of losses over the life of exposure that considers historical, current and forecasted information. Expanded disclosures related to the methods used to estimate the losses as well as a specific disaggregation of balances for financial assets are also required. This standard is effective for annual periods beginning after December 15, 2019 and interim periods within those annual periods. The Partnership does not expect this standard will have a material effect on its consolidated financial statements.
